The use of qualitative methodologies in speech and language therapy has grown over the past two decades, and there is now a body of literature, both generally describing qualitative research, and detailing its applicability to health practice(s). However, there has been only limited profession-specific discussion of qualitative methodologies and their potential application to speech and language therapy. To describe the methodology of grounded theory, and to explain how it might usefully be applied to areas of speech and language research where theoretical frameworks or models are lacking. Grounded theory as a methodology for inductive theory-building from qualitative data is explained and discussed. Some differences between 'modes' of grounded theory are clarified and areas of controversy within the literature are highlighted. The past application of grounded theory to speech and language therapy, and its potential for informing research and clinical practice, are examined. This paper provides an in-depth critique of a qualitative research methodology, including an overview of the main difference between two major 'modes'. The article supports the application of a theory-building approach in the profession, which is sometimes complex to learn and apply, but worthwhile in its results. Grounded theory as a methodology has much to offer speech and language therapists and researchers. Although the majority of research and discussion around this methodology has rested within sociology and nursing, grounded theory can be applied by researchers in any field, including speech and language therapists. The benefit of the grounded theory method to researchers and practitioners lies in its application to social processes and human interactions. The resulting theory may support further research in the speech and language therapy profession.

IT is getting an increasing importance in hospitals. In this context, major IT decisions are often made by CEOs who are not necessarily IT experts. Therefore, this study aimed at a) exploring different types of IT decision makers at CEO level, b) identifying hypotheses if trust exists between these different types of CEOs and their CIOs and c) building hypotheses on potential consequences regarding risk taking and innovation. To this end, 14 qualitative interviews with German hospital CEOs were conducted to explore the research questions. The study revealed three major types: IT savvy CEOs, IT enthusiastic CEOs and IT indifferent CEOs. Depending on these types, their relationship with the CIO varied in terms of trust and common language. In case of IT indifferent CEOs, a potential vicious circle of lack of IT knowledge, missing trust, low willingness to take risks and low innovation power could be identified. In order to break of this circle, CEOs seem to need more IT knowledge and/or greater trust in their CIO.

Living in a material world: Development and evaluation of a new materials science course for non-science majors

Brust, Gregory John

This study was designed to discover if there is a difference in the scientific attitudes and process skills between a group of students who were instructed with Living in a Material World and groups of students in non-science majors sections of introductory biology, chemistry, and geology courses at the University of Southern Mississippi (USM). Each of the four courses utilized different instructional techniques. Students' scientific attitudes were measured with the Scientific Attitudes Inventory (SAI II) and their knowledge of science process skills were measured with the Test of Integrated Process Skills (TIPS II). The Group Assessment of Logical Thinking (GALT) was also administered to determine if the cognitive levels of students are comparable. A series of four questionnaires called Qualitative Course Assessments (QCA) were also administered to students in the experimental course to evaluate subtle changes in their understanding of the nature and processes of science and attitudes towards science. Student responses to the QCA questionnaires were triangulated with results of the qualitative instruments, and students' work on the final project. Results of the GALT found a significant difference in the cognitive levels of students in the experimental course (PSC 190) and in one of the control group, the introductory biology (BSC 107). Results of the SAI II and the TIPS II found no significant difference between the experimental group and the control groups. Qualitative analyses of students' responses to selected questions from the TIPS II, selected items on the SAI II, QCA questionnaires, and Materials that Fly project reports demonstrate an improvement in the understanding of the nature and processes of science and a change to positive attitude toward science of students in the experimental group. Students indicated that hands-on, inquiry-based labs and performance assessment were the most effective methods for their learning. These results indicate that science courses for non-science majors should focus on connections to students' daily lives while utilizing an STS curriculum and inquiry-based activities. Future research could focus on long term effects of this type of course as well as the effectiveness of these teaching methods for science majors.

To provide theoretical basis for breeding good variety of Dendrobium denneanum, agronomic and qualitative characters of 4 different lines and relationships among them were studied. The stem length, stem diameter, leaf length, leaf width, length/ width ratio and leaf area were measured. The single fresh and dry stem was weighed and drying rate was calculated. The contents of polysaccharides and total alkaloids were determined by sulfuric acid-phenol colorimetry and acid-dye colorimetry, respectively. The correlations between characters were analyzed. The results showed that differences in major agronomic characters between four lines were significant. The plant types of dq-1 and dq-2 were higher, dq-3 was medium and dq-4 was lower. The fresh weigh of stem and content of polysaccharides were the highest in dq-2, 7.81 g and 14.33%. While the highest content of total alkaloids and was 0. 486% in dq-3. There were significant correlations between agronomic characters, but these characters had low or non correlations with qualitative characters such as polysaccharides and total alkaloids. It was shown that the content of polysaccharides and total alkaloids were significantly different among 4 lines of D. denneanum, which could be selected for different uses.

The collagen phase in bone is known to undergo major changes during growth and maturation. The objective of this study is to clarify whether Fourier transform infrared (FTIR) microspectroscopy, coupled with cluster analysis, can detect quantitative and qualitative changes in the collagen matrix of subchondral bone in horses during maturation and growth. Equine subchondral bone samples (n = 29) from the proximal joint surface of the first phalanx are prepared from two sites subjected to different loading conditions. Three age groups are studied: newborn (0 days old), immature (5 to 11 months old), and adult (6 to 10 years old) horses. Spatial collagen content and collagen cross-link ratio are quantified from the spectra. Additionally, normalized second derivative spectra of samples are clustered using the k-means clustering algorithm. In quantitative analysis, collagen content in the subchondral bone increases rapidly between the newborn and immature horses. The collagen cross-link ratio increases significantly with age. In qualitative analysis, clustering is able to separate newborn and adult samples into two different groups. The immature samples display some nonhomogeneity. In conclusion, this is the first study showing that FTIR spectral imaging combined with clustering techniques can detect quantitative and qualitative changes in the collagen matrix of subchondral bone during growth and maturation.

Occupations at Risk and Organizational Well-Being: An Empirical Test of a Job Insecurity Integrated Model

One of the more visible effects of the societal changes is the increased feelings of uncertainty in the workforce. In fact, job insecurity represents a crucial occupational risk factor and a major job stressor that has negative consequences on both organizational well-being and individual health. Many studies have focused on the consequences about the fear and the perception of losing the job as a whole (called quantitative job insecurity), while more recently research has begun to examine more extensively the worries and the perceptions of losing valued job features (called qualitative job insecurity). The vast majority of the studies, however, have investigated the effects of quantitative and qualitative job insecurity separately. In this paper, we proposed the Job Insecurity Integrated Model aimed to examine the effects of quantitative job insecurity and qualitative job insecurity on their short-term and long-term outcomes. This model was empirically tested in two independent studies, hypothesizing that qualitative job insecurity mediated the effects of quantitative job insecurity on different outcomes, such as work engagement and organizational identification (Study 1), and job satisfaction, commitment, psychological stress and turnover intention (Study 2). Study 1 was conducted on 329 employees in private firms, while Study 2 on 278 employees in both public sector and private firms. Results robustly showed that qualitative job insecurity totally mediated the effects of quantitative on all the considered outcomes. By showing that the effects of quantitative job insecurity on its outcomes passed through qualitative job insecurity, the Job Insecurity Integrated Model contributes to clarifying previous findings in job insecurity research and puts forward a framework that could profitably produce new investigations with important theoretical and practical implications.

Can We Integrate Qualitative and Quantitative Research in Science Education?

NASA Astrophysics Data System (ADS)

Niaz, Mansoor

The main objective of this paper is to emphasize the importance of integrating qualitative and quantitative research methodologies in science education. It is argued that the Kuhnian in commensurability thesis (a major source of inspiration for qualitative researchers) represents an obstacle for this integration. A major thesis of the paper is that qualitative researchers have interpreted the increased popularity of their paradigm (research programme) as a revolutionary break through in the Kuhnian sense. A review of the literature in areas relevant to science education shows that researchers are far from advocating qualitative research as the only methodology. It is concluded that competition between divergent approaches to research in science education (cf. Lakatos, 1970) would provide a better forum for a productive sharing of research experiences.

OBJECTIVE: To discuss the value of promoting coexistent and complementary relationships between qualitative and quantitative research methods as illustrated by presentations made by four respected health services researchers who described their experiences in multi-method projects. DATA SOURCES: Presentations and publications related to the four research projects, which described key substantive and methodological areas that had been addressed with qualitative techniques. PRINCIPAL FINDINGS: Sponsor interest in timely, insightful, and reality-anchored evidence has provided a strong base of support for the incorporation of qualitative methods into major contemporary policy research studies. In addition, many issues may be suitable for study only with qualitative methods because of their complexity, their emergent nature, or because of the need to revisit and reexamine previously untested assumptions. CONCLUSION: Experiences from the four projects, as well as from other recent health services studies with major qualitative components, support the assertion that the interests of sponsors in the policy realm and pressure from them suppress some of the traditional tensions and antagonisms between qualitative and quantitative methods.

Qualitative research methods are increasingly being used across disciplines because of their ability to help investigators understand the perspectives of participants in their own words. However, qualitative analysis is a laborious and resource-intensive process. To achieve depth, researchers are limited to smaller sample sizes when analyzing text data. One potential method to address this concern is natural language processing (NLP). Qualitative text analysis involves researchers reading data, assigning code labels, and iteratively developing findings; NLP has the potential to automate part of this process. Unfortunately, little methodological research has been done to compare automatic coding using NLP techniques and qualitative coding, which is critical to establish the viability of NLP as a useful, rigorous analysis procedure. The purpose of this study was to compare the utility of a traditional qualitative text analysis, an NLP analysis, and an augmented approach that combines qualitative and NLP methods. We conducted a 2-arm cross-over experiment to compare qualitative and NLP approaches to analyze data generated through 2 text (short message service) message survey questions, one about prescription drugs and the other about police interactions, sent to youth aged 14-24 years. We randomly assigned a question to each of the 2 experienced qualitative analysis teams for independent coding and analysis before receiving NLP results. A third team separately conducted NLP analysis of the same 2 questions. We examined the results of our analyses to compare (1) the similarity of findings derived, (2) the quality of inferences generated, and (3) the time spent in analysis. The qualitative-only analysis for the drug question (n=58) yielded 4 major findings, whereas the NLP analysis yielded 3 findings that missed contextual elements. The qualitative and NLP-augmented analysis was the most comprehensive. For the police question (n=68), the qualitative-only analysis yielded 4 primary findings and the NLP-only analysis yielded 4 slightly different findings. Again, the augmented qualitative and NLP analysis was the most comprehensive and produced the highest quality inferences, increasing our depth of understanding (ie, details and frequencies). In terms of time, the NLP-only approach was quicker than the qualitative-only approach for the drug (120 vs 270 minutes) and police (40 vs 270 minutes) questions. An approach beginning with qualitative analysis followed by qualitative- or NLP-augmented analysis took longer time than that beginning with NLP for both drug (450 vs 240 minutes) and police (390 vs 220 minutes) questions. NLP provides both a foundation to code qualitatively more quickly and a method to validate qualitative findings. NLP methods were able to identify major themes found with traditional qualitative analysis but were not useful in identifying nuances. Traditional qualitative text analysis added important details and context. ©Timothy C Guetterman, Tammy Chang, Melissa DeJonckheere, Tanmay Basu, Elizabeth Scruggs, VG Vinod Vydiswaran.

2003-01-01

Two CD-ROMs from a series dealing with various major aspects of cell biology are evaluated in this paper using quantitative and qualitative approaches. The findings delimit similarities and differences of the two CD-ROMs and shed light on how the programs could be used in the learning process and how they should not be. The overall impression, as well as the graphical and technical features, received a predominantly good rating. The defined target groups were reached (e.g., students in secondary schools), different learning approaches were supported (e.g., discovery and autonomous learning), the CD-ROMs' usability was assessed as being easy and intuitive, and the majority of the evaluators were satisfied with the level of interactivity. Navigational problems encountered in CD-ROM 1 were overcome by a successful implementation of new navigational functions in CD-ROM 2. Most students found the CD-ROM to be a suitable complement to, or an extension of, their lessons. We conclude that many, but not all of the requirements for the various stages of the learning process could be satisfied with the existing CD-ROMs. The requirements not met are discussed to obtain insights that could help to improve the production of multimedia learning material. The use of quantitative and qualitative approaches in the evaluation of learning modules is discussed, as the study began by collecting and analyzing anecdotal reviews and was then extended to include a qualitative evaluation.

2010-01-01

Background Little is known about how culture influences menopausal symptom experience, and few comparative qualitative studies have been conducted among multiethnic groups of midlife women in the United States. Objectives To explore commonalities and differences in menopausal symptom experience among four major ethnic groups in the US (Whites, Hispanics, African Americans, and Asians). Methods This was a secondary analysis of qualitative data from a larger national Internet-based study. The qualitative data from 90 middle-aged women in the US who attended four ethnic-specific online forums of the larger study were examined using thematic analysis. Results The themes reflecting commonalities across the ethnic groups were: just a part of life, trying to be optimistic, getting support, and more information needed. The themes reflecting the differences among the ethnic groups were: open and closed, universal and unique, and controlling and minimizing. Overall, the findings indicated positive changes in women’s menopausal symptom experience, and supported the existence of cultural influences on women’s menopausal symptom experience across the ethnic groups. Discussion Systematic efforts need to be made to empower midlife women in their management of menopausal symptoms. PMID:20010042

2017-08-01

Understanding public priorities for biobanks is vital for maximising utility and efficiency of genetic research and maintaining respect for donors. This research directly assessed the relative importance the public place on different expectations of biobanks. Quantitative and qualitative results from a national sample of 800 Australians revealed that the majority attributed more importance to protecting privacy and ethical conduct than maximising new healthcare benefits, which was in turn viewed as more important than obtaining specific consent, benefit sharing, collaborating and sharing data. A latent class analysis identified two distinct classes displaying different patterns of expectations. One placed higher priority on behaviours that respect the donor ( n = 623), the other on accelerating science ( n = 278). Additional expectations derived from qualitative data included the need for biobanks to be transparent and to prioritise their research focus, educate the public and address commercialisation.

DeBeck, George; Demaree, Dedra

2012-02-01

In the spring term of 2010, Oregon State University (OSU) began using a SCALE-UP style classroom in the instruction of the introductory calculus-based physics series. Instruction in this classroom was conducted in weekly two-hour sessions facilitated by the primary professor and either two graduate teaching assistants (GTAs) or a graduate teaching assistant and an undergraduate learning assistant (LA). During the course of instruction, two of the eight tables in the room were audio and video recorded. We examine the practices of the GTAs in interacting with the students through both qualitative and quantitative analyses of these recordings. Quantitatively, significant differences are seen between the most experienced GTA and the rest. A major difference in confidence is also observed in the qualitative analysis of this GTA compared to a less experienced GTA.

DESIGN Cross-sectional survey. SETTING Four colleges of pharmacy in midwestern United States. PARTICIPANTS 516 graduating student pharmacists. INTERVENTIONS Online survey with open-ended questions. MAIN OUTCOME MEASURES Qualitative analysis of responses and themes. RESULTS A total of 212 student pharmacists completed surveys (41% response rate). Mean (± SD) age was 25.2 ± 4.6 years, and 72% of respondents were women. Major overarching themes identified in the qualitative analysis were separation of personal and professional lives, how accountability for actions should vary by severity, and the extent of representation of the students' character on social media. CONCLUSION Identified themes provided important insights into the ways in which student pharmacists view social media and use this widely accessible means of personal communication.

Gender in the Geosciences: Factors Supporting the Recruitment and Retention of Women in the Undergraduate Major

The proportion of women earning undergraduate geoscience degrees has remained about 40% for over a decade. Little research has investigated why women select and persist in a geoscience major. This study addresses why students major in the geosciences and why some programs are more successful at recruiting and retaining female students. We collected interview and survey data from faculty and students at six public US universities. Four sites had a low proportion of female degree recipients (< 38%) and two sites had a high proportion of female degree recipients (> 48%). 408 students (64% female) completed surveys. Interviews were conducted with 49 faculty members and 151 students. Survey data analysis showed that interest/identity and transformative experiences were significant predictors of students' decision to major in geoscience. Institutional barriers and supports were significant predictors of confidence in the major while connection to instructor predicted students' intent to major. Analysis of pre- and post-course surveys show that students with a greater connection to instructors and students whose instructors expressed more passion for the content also reported higher levels of transformative experiences. This effect was especially pronounced for women and was a significant predictor of persistence in the major. Qualitative data show differences in departmental practices and climate between low and high female graduation sites. High sites used many student-centered approaches to teaching, had extensive opportunities for and a high number of undergraduate students involved in research, and had many opportunities for faculty-student interaction outside of class. Low sites had few of these practices. Qualitative data also showed differences in the gendered equity climate between high and low sites. High sites had more positive gender equity climates and low sites had more negative gender equity climates. At this time, we do not fully understand the causal relationships among all of these findings and higher female graduation rates, but this research is ongoing and these relationships are a focus of our final year of this research project.

The major goal of the research was to develop flexible, effective methods for representing the qualitative knowledge necessary for solving large problems that require symbolic reasoning as well as numerical computation. The research focused on integrating different representation methods to describe different kinds of knowledge more effectively than any one method can alone. In particular, emphasis was placed on representing and using spatial information about three dimensional objects and constraints on the arrangement of these objects in space. Another major theme is the development of robust machine learning programs that can be integrated with a variety of intelligent systems. To achieve this goal, learning methods were designed, implemented and experimented within several different problem solving environments.

A series of 376 cotton-polyester (PET) blend fabrics were studied by a portable near-infrared (NIR) spectrometer. A NIR semi-quantitative-qualitative calibration model was established by Partial Least Squares (PLS) method combined with qualitative identification coefficient. In this process, PLS method in a quantitative analysis was used as a correction method, and the qualitative identification coefficient was set by the content of cotton and polyester in blend fabrics. Cotton-polyester blend fabrics were identified qualitatively by the model and their relative contents were obtained quantitatively, the model can be used for semi-quantitative identification analysis. In the course of establishing the model, the noise and baseline drift of the spectra were eliminated by Savitzky-Golay(S-G) derivative. The influence of waveband selection and different pre-processing method was also studied in the qualitative calibration model. The major absorption bands of 100% cotton samples were in the 1400~1600 nm region, and the one for 100% polyester were around 1600~1800 nm, the absorption intensity was enhancing with the content increasing of cotton or polyester. Therefore, the cotton-polyester's major absorption region was selected as the base waveband, the optimal waveband (1100~2500 nm) was found by expanding the waveband in two directions (the correlation coefficient was 0.6, and wave-point number was 934). The validation samples were predicted by the calibration model, the results showed that the model evaluation parameters was optimum in the 1100~2500 nm region, and the combination of S-G derivative, multiplicative scatter correction (MSC) and mean centering was used as the pre-processing method. RC (relational coefficient of calibration) value was 0.978, RP (relational coefficient of prediction) value was 0.940, SEC (standard error of calibration) value was 1.264, SEP (standard error of prediction) value was 1.590, and the sample's recognition accuracy was up to 93.4%. It showed that the cotton-polyester blend fabrics could be predicted by the semi-quantitative-qualitative calibration model.

Biology teachers' dissection practices and the influences that lead to their adoption: An exploratory research

NASA Astrophysics Data System (ADS)

Milano, Regina Nicole

The lack of resolution in the on-going animal dissection debate inspired this mixed methods study to identify Connecticut secondary biology teachers' dissection practices and the influences that lead to their adoption. Qualitative findings indicate past experiences, managing objections to dissection, school culture, goals of biology teaching and ethics as major influences on dissection practices with 58.4% (n=7) of the sample dissecting and 41.6% not dissecting (n=5). Quantitative findings reveal gender, standards and curriculum, advantages of dissection and experiences as a student as major influences on dissection practices with 71.9% (n=92) of the sample dissecting and 28.1% (n=36) not dissecting. The study concludes that dissection policies are necessary and imminent in Connecticut school districts. Furthermore, it advises teacher-initiated, qualitative and quantitative assessments to expose disparities between student dissection perspectives and their own, prior to conducting dissection. Finally, it provides suggestions for addressing potential differences including administrative involvement.

Mhc supertypes confer both qualitative and quantitative resistance to avian malaria infections in a wild bird population

Major histocompatibility complex (Mhc) genes are believed to play a key role in the genetic basis of disease control. Although numerous studies have sought links between Mhc and disease prevalence, many have ignored the ecological and epidemiological aspects of the host–parasite interaction. Consequently, interpreting associations between prevalence and Mhc has been difficult, whereas discriminating alleles for qualitative resistance, quantitative resistance and susceptibility remains challenging. Moreover, most studies to date have quantified associations between genotypes and disease status, overlooking the complex relationship between genotype and the properties of the Mhc molecule that interacts with parasites. Here, we address these problems and demonstrate avian malaria (Plasmodium) parasite species-specific associations with functional properties of Mhc molecules (Mhc supertypes) in a wild great tit (Parus major) population. We further show that correctly interpreting these associations depends crucially on understanding the spatial variation in risk of infection and the fitness effects of infection. We report that a single Mhc supertype confers qualitative resistance to Plasmodium relictum, whereas a different Mhc supertype confers quantitative resistance to Plasmodium circumflexum infections. Furthermore, we demonstrate common functional properties of Plasmodium-resistance alleles in passerine birds, suggesting this is a model system for parasite–Mhc associations in the wild.

There has been limited research on physicians' perceptions of the specialty characteristics that are needed to sustain a successful career in medical specialties in Korea. Medical Specialty Preference Inventory in the United States or SCI59 (specialty choice inventory) in the United Kingdom are implemented to help medical students plan their careers. The purpose of this study was to explore the characteristics of the major specialties in Korea. Twelve physicians from different specialties participated in an exploratory study consisting of qualitative interviews about the personal ability and emotional characteristics and job attributes of each specialty. The collected data were analysed with content analysis methods. Twelve codes were extracted for ability & skill attributes, 23 codes for emotion & attitude attributes, and 12 codes for job attributes. Each specialty shows a different profile in terms of its characteristic attributes. The findings have implications for the design of career planning programs for medical students.

Effect of rational and irrational statements on intensity and 'inappropriateness' of emotional distress and irrational beliefs in psychotherapy patients.

PubMed

Cramer, D; Kupshik, G

1993-09-01

Ellis's rational-emotive theory postulates that since irrational statements augment emotional distress, replacing irrational with rational statements should lessen distress. This hypothesis was tested in the initial stages of psychotherapy by having 13 and 14 clinical out-patients respectively repeat for one minute either rational or irrational statements about their major presenting psychological problem. The distinction by Ellis & Harper (1975) that 'inappropriate' emotions differ qualitatively from 'appropriate' emotions was also examined. Although the experimental intervention had no effect on a post-test measure of irrational beliefs, patients repeating rational statements had significantly lower appropriate and inappropriate negative emotions at post-test, suggesting that inappropriate emotions do not differ qualitatively from appropriate emotions and that making rational statements may lower emotional distress in patients. Patients reiterating irrational statements showed no change in emotions, implying that these kinds of irrational cognitions may have already been present.

Implementing major system change in healthcare is not well understood. This gap may be addressed by analysing change in terms of interrelated components identified in the implementation literature, including decision to change, intervention selection, implementation approaches, implementation outcomes, and intervention outcomes. We conducted a qualitative study of two cases of major system change: the centralisation of acute stroke services in Manchester and London, which were associated with significantly different implementation outcomes (fidelity to referral pathway) and intervention outcomes (provision of evidence-based care, patient mortality). We interviewed stakeholders at national, pan-regional, and service-levels (n = 125) and analysed 653 documents. Using a framework developed for this study from the implementation science literature, we examined factors influencing implementation approaches; how these approaches interacted with the models selected to influence implementation outcomes; and their relationship to intervention outcomes. London and Manchester's differing implementation outcomes were influenced by the different service models selected and implementation approaches used. Fidelity to the referral pathway was higher in London, where a 'simpler', more inclusive model was used, implemented with a 'big bang' launch and 'hands-on' facilitation by stroke clinical networks. In contrast, a phased approach of a more complex pathway was used in Manchester, and the network acted more as a platform to share learning. Service development occurred more uniformly in London, where service specifications were linked to financial incentives, and achieving standards was a condition of service launch, in contrast to Manchester. 'Hands-on' network facilitation, in the form of dedicated project management support, contributed to achievement of these standards in London; such facilitation processes were less evident in Manchester. Using acute stroke service centralisation in London and Manchester as an example, interaction between model selected and implementation approaches significantly influenced fidelity to the model. The contrasting implementation outcomes may have affected differences in provision of evidence-based care and patient mortality. The framework used in this analysis may support planning and evaluating major system changes, but would benefit from application in different healthcare contexts.

The role of qualitative research in psychological journals.

Kidd, Sean A

2002-03-01

The acceptance of qualitative research in 15 journals published and distributed by the American Psychological Association (APA) was investigated. This investigation included a PsycINFO search using the keyword qualitative, an analysis of 15 APA journals for frequency of qualitative publication, a content analysis of the journal descriptions, and the results of qualitative interviews with 10 of the chief editors of those journals. The results indicate that there exists a substantial amount of interest in the potential contribution of qualitative methods in major psychological journals, although this interest is not ubiquitous, well defined, or communicated. These findings highlight the need for APA to state its position regarding the applicability of qualitative methods in the study of psychology.

We studied some aspects of the quantitative and qualitative features of heterologous recombinant (re) virus-vector-induced, antigen-specific CD8(+) T cells against Trypanosoma cruzi. We used three different, highly attenuated re-viruses, i.e., influenza virus, adenovirus and vaccinia virus, which all expressed a single, T. cruzi antigen-derived CD8(+) T-cell epitope. The use of two out of three vectors or the triple virus-vector vaccination regimen not only confirmed that the re-vaccinia virus, which was placed last in order for sequential immunisation, was an effective booster for the CD8(+) T-cell immunity in terms of the number of antigen-specific CD8(+) T cells, but also demonstrated that (i) the majority of cells exhibit the effector memory (T(EM)) phenotype, (ii) robustly secrete IFN-γ, (iii) express higher intensity of the CD122 molecule and (iv) present protective activity against T. cruzi infection. In contrast, placing the re-influenza virus last in sequential immunisation had a detrimental effect on the quantitative and qualitative features of CD8(+) T cells. The triple virus-vector vaccination was more effective at inducing a stronger CD8(+) T-cell immunity than using two re-viruses. The different quantitative and qualitative features of CD8(+) T cells induced by different immunisation regimens support the notion that the refinement of the best choice of multiple virus-vector combinations is indispensable for the induction of a maximum number of CD8(+) T cells of high quality.

Sedation for electroencephalography in uncooperative patients is a controversial issue because majority of sedatives, hypnotics, and general anesthetics interfere with the brain's electrical activity. Chloral hydrate (CH) is typically used for this sedation, and dexmedetomidine (DEX) was recently tested because preliminary data suggest that this drug does not affect the electroencephalogram (EEG). The aim of the present study was to compare the EEG pattern during DEX or CH sedation to test the hypothesis that both drugs exert similar effects on the EEG. A total of 17 patients underwent 2 EEGs on 2 separate occasions, one with DEX and the other with CH. The EEG qualitative variables included the phases of sleep and the background activity. The EEG quantitative analysis was performed during the first 2 minutes of the second stage of sleep. The EEG quantitative variables included density, duration, and amplitude of the sleep spindles and absolute spectral power. The results showed that the qualitative analysis, density, duration, and amplitude of sleep spindles did not differ between DEX and CH sedation. The power of the slow-frequency bands (δ and θ) was higher with DEX, but the power of the faster-frequency bands (α and β) was higher with CH. The total power was lower with DEX than with CH. The differences of DEX and CH in EEG power did not change the EEG qualitative interpretation, which was similar with the 2 drugs. Other studies comparing natural sleep and sleep induced by these drugs are needed to clarify the clinical relevance of the observed EEG quantitative differences.

Polyporus umbellatus is a widely used diuretic herbal medicine. In this study, a high-performance liquid chromatography coupled with atmospheric pressure chemical ionization-mass spectrometric detection (HPLC-APCI-MS) method was developed for qualitative and quantitative analysis of steroids, as well as for the quality control of Polyporus umbellatus. The selectivity, reproducibility and sensitivity were compared with HPLC with photodiode array detection and evaporative light scattering detection (ELSD). Selective ion monitoring in positive mode was used for qualitative and quantitative analysis of eight major components and beta-ecdysterone was used as the internal standard. Limits of detection and quantification fell in the ranges 7-21 and 18-63 ng/mL for the eight analytes with an injection of 10 microL samples, and all calibration curves showed good linear regression (r(2) > 0.9919) within the test range. The quantitative results demonstrated that samples from different localities showed different qualities. Advantages, in comparison with conventional HPLC-diode array detection and HPLC-ELSD, are that reliable identification of target compounds could be achieved by accurate mass measurements along with characteristic retention time, and the great enhancement in selectivity and sensitivity allows identification and quantification of low levels of constituents in complex Polyporus umbellatus matrixes.

Qualitative research designs are being used increasingly in dental research. This paper describes the extent and range of dental research in which qualitative methods have been employed as well as the techniques of data collection and analysis preferred by dental researchers. A scoping review was conducted to locate studies published in dental journals, which reported the use of qualitative methods. Data concerning the focus of the research and the reported qualitative techniques were extracted. Studies included in the review totalled 197. The majority of qualitative research captured in this scoping study focussed on three main areas: dental education, professional dental and dental educators' activities and experiences and the patient/public perceptions. Interviews and focus group discussions were the most commonly selected techniques for data collection. The majority of the studies included in the scoping review had a focus on education of dental professionals the activities of dental professionals or the reported perceptions of or experiences with dental services by patients or members of the public. Little research was located, which explored peoples' personal experience of dental conditions. Research reported in dental publications has a heavy bias towards the use of focus groups and interview data collection techniques. © 2012 John Wiley & Sons A/S.

Individuals with ADHD appear to respond differently to incentives than their peers. This could be due to a general altered sensitivity to reinforcers. However, apart from differences in the degree of motivation, individuals with ADHD might also be motivated by qualitatively different factors. This study aimed to harvest a range of motivational factors and identify ADHD-related qualitative differences in motivation, from the adolescent's point of view. Semi-structured interviews allowing participants to describe what motivates them in daily life were conducted with young adolescents (9-16 years) with and without ADHD. Thematic analysis was undertaken using NVivo software. Major themes relating to motivation were identified from the interview data. These were: (1) achieving a sense of togetherness; (2) feeling competent; (3) fulfilling a need for variation; (4) gaining pleasure from applying effort to achieve a goal; (5) valuing social reinforcement; (6) desiring to be absorbed/forget problems; (7) feeling free and independent, (8) attaining material reinforcement; and (9) an enjoyment of bodily stimulation. The theme structure was very similar for both groups. However, individuals with ADHD differed in some specifics: their focus on the passing of time, the absence of preference for predictable and familiar tasks, and their less elaborate description of the togetherness theme. A broad range of motivational themes was identified, stretching beyond the current focus of ADHD research and motivational theories. Similarities and differences in motivational values of individuals with and without ADHD should be taken into account in reward sensitivity research, and in psychological treatment.

Elbow joint adductor moment arm as an indicator of forelimb posture in extinct quadrupedal tetrapods

Fujiwara, Shin-ichi; Hutchinson, John R.

2012-01-01

Forelimb posture has been a controversial aspect of reconstructing locomotor behaviour in extinct quadrupedal tetrapods. This is partly owing to the qualitative and subjective nature of typical methods, which focus on bony articulations that are often ambiguous and unvalidated postural indicators. Here we outline a new, quantitatively based forelimb posture index that is applicable to a majority of extant tetrapods. By determining the degree of elbow joint adduction/abduction mobility in several tetrapods, the carpal flexor muscles were determined to also play a role as elbow adductors. Such adduction may play a major role during the stance phase in sprawling postures. This role is different from those of upright/sagittal and sloth-like creeping postures, which, respectively, depend more on elbow extensors and flexors. Our measurements of elbow muscle moment arms in 318 extant tetrapod skeletons (Lissamphibia, Synapsida and Reptilia: 33 major clades and 263 genera) revealed that sprawling, sagittal and creeping tetrapods, respectively, emphasize elbow adductor, extensor and flexor muscles. Furthermore, scansorial and non-scansorial taxa, respectively, emphasize flexors and extensors. Thus, forelimb postures of extinct tetrapods can be qualitatively classified based on our quantitative index. Using this method, we find that Triceratops (Ceratopsidae), Anhanguera (Pterosauria) and desmostylian mammals are categorized as upright/sagittally locomoting taxa. PMID:22357261

Model for understanding consumer textural food choice

2015-01-01

The current paradigm for developing products that will match the marketing messaging is flawed because the drivers of product choice and satisfaction based on texture are misunderstood. Qualitative research across 10 years has led to the thesis explored in this research that individuals have a preferred way to manipulate food in their mouths (i.e., mouth behavior) and that this behavior is a major driver of food choice, satisfaction, and the desire to repurchase. Texture, which is currently thought to be a major driver of product choice, is a secondary factor, and is important only in that it supports the primary driver—mouth behavior. A model for mouth behavior is proposed and the qualitative research supporting the identification of different mouth behaviors is presented. The development of a trademarked typing tool for characterizing mouth behavior is described along with quantitative substantiation of the tool's ability to group individuals by mouth behavior. The use of these four groups to understand textural preferences and the implications for a variety of areas including product design and weight management are explored. PMID:25987995

Introduction Anaemia continues to be a major hurdle to achieve optimum health in Indian population context. Although government continues to promote Iron Folic Acid (IFA) supplementation as one of the key strategies to combat with burden of anaemia, the expected level of IFA consumption and subsequent anaemia reduction could not be achieved. This study tries to investigate those influences, concerns, experiences and behaviour from an end user perspective through a qualitative methodology which may affect the IFA consumption ambi-directionally. Aim To explore and understand the several aspects related with anaemia and IFA supplementation with special emphasis to reveal the contributory factors behind low level of IFA consumption at consumer end. Materials and Methods A community based qualitative study was conducted in clusters identified through multileveled stratification from a state of central India. A conceptual construct was made in priory for this study. As the research question was related with policy, this study adapted a framework technique for making interview topic guides. Two consumers and two non consumers from each identified cluster were interviewed in depth. The data obtained through 160 in depth interviews (from 80 consumers and 80 non consumers) was utilized for thematic framework, linkage association and to typify the phenomenon. Results Ignorance, difficult intake, meaninglessness, misconceptions and discontentment with the system were the major dimensions (sub themes) associated with discontinuation. All these sub themes were further converged into major theme of informational discontinuity. Investigators further typified the users/non users into persistent user, potential defaulters, impending defaulters and absolute non users. Conclusion Informational gap seems to be the fundamental factor behind sub optimum IFA consumption. On a policy perspective, all the attempts should be done to instigate arise felt need’ among target groups for IFA consumption. PMID:28658813

Mixed methods research, the use of both qualitative and quantitative methods within 1 program of study, is becoming increasingly popular to allow investigators to explore patient experiences (qualitative) and also measure outcomes (quantitative). Coronary artery disease and its risk factors are some of the most studied conditions; however, the extent to which mixed methods studies are being conducted in these content areas is unknown. We sought to comprehensively describe the characteristics of published mixed methods studies on coronary artery disease and major risk factors (diabetes mellitus and hypertension). We conducted a scoping review of the literature indexed in PubMed, Medline, EMBASE, and CINAHL. We identified 811 abstracts for screening, of which 254 articles underwent full-text review and 97 reports of 81 studies met criteria for inclusion. The majority of studies in this area were conducted in the past 10 years by nurse researchers from the United States and United Kingdom. Diabetes mellitus was the most common content area for mixed methods investigation (compared with coronary artery disease and hypertension). Most authors described their rationale for using mixed methods as complementarity and did not describe study priority or how they reconciled differences in methodological paradigms. Some mixed methods study designs were more commonly used than others, including concurrent timing and integration at the interpretation stage. Qualitative strands were most commonly descriptive studies using interviews for data collection. Quantitative strands were most commonly cross-sectional observational studies, which relied heavily on self-report data such as surveys and scales. Although mixed methods research is becoming increasingly popular in the area of coronary artery disease and its risk factors, many of the more advanced mixed methods, qualitative, and quantitative techniques have not been commonly used in these areas. © 2016 American Heart Association, Inc.

Conceptual model of a coastal hydrosystem in a semi-arid environment subjected to the climate change: the case of Lavrion, Greece

Groundwater management in arid areas has become a major issue worldwide, and it is expected to be exacerbated due to climate change. Low annual precipitation and high evaporation potential are the key features of these areas, with additional pressure added to the system due to abstractions for irrigation and water supply purposes. Typical example of such scenarios exist in the Mediterranean area, where drought and water scarcity, especially in the warm period of the hydrological year, give rise to major management issues in coastal areas. Among the different solutions, the implementation of Managed Aquifer Recharge (MAR) schemes have been suggested in the EU FP7 project MARSOL (Demonstrating Managed Aquifer Recharge as a Solution to Water Scarcity and Drought). In the project, different sites across the Mediterranean are tested for investigating the viability of various MAR techniques in different hydrological systems facing qualitative and quantitative deterioration of their groundwater resources. The coastal hydrosystem of Lavrion was selected due to its typical Mediterranean characteristics (climatic, hydrologic, hydrogeological, geological etc.); all within a rather small area of extent ( < 50km2), that render it as a reference site for hydrologic modeling applications. It consists of a set of aquifer layers (karstified limestone and alluvial) which are hydraulically connected to the sea and an ephemeral torrent (wadi) that flows through a typical small Mediterranean alluvial valley. The major water resources problems of the area are mainly qualitative issues of the groundwaters; in specific: (i) seawater intrusion, (ii) nitrate contamination and (iii) heavy metal pollution due to past and recent mining and metallurgical activities The modelling approach will include the development of three distinct models that will be integrated. The aim is to depict how systems with characteristics like the ones mentioned above perform and, which different scenarios can be applied, aiming at identifying the most viable (with respect to water budget) MAR strategy for the specific area. Meteorological data, field data and site investigations provide the input data for all the different models. The field activities already conducted included: an inventory of all existing pumping wells; the development of a monitoring network for qualitative and quantitative environmental data acquisition at different scales and hydrologic zones; installation of multi-level piezometers for tailored monitoring of the seawater wedge; and geophysical surveys of subsurface characterization. The combination of literature review and field investigations led to the development of the conceptual model of the area along with the realization of the spatial distribution of each model. The hydraulic connections of the two aquifers, the surface water system and the sea have been identified and the upcoming activities aim in quantifying them and include them in the models being under development. The groundwater chemical characteristics have been examined, with results showing the major influence from seawater intrusion. All the data mentioned above are used for the development of the integrated hydrological model of the Lavrion area.

To document the organisational response of Furness General Hospital to the large outbreak of legionnaire's disease in April 2002 and assess the contribution made by the hospital's major incident plan. Qualitative analysis of interview transcripts and written comments from some staff involved in the management of the incident. Documentary analysis of major incident plan and other written materials. The incident posed considerable managerial and clinical problems and this paper describes how they were overcome. In particular, strategies for dealing with supply (of staff, beds, and resources) and managing demand (by liaising with primary care and the public) seem to have been successful. Many functions necessary for managing the incident were poorly dealt with in the plan, especially procedures for handling the news media and liaison with agencies outside the hospital. Lack of explicit guidance appeared not to hinder the organisational response. There may have been an unspoken high level decision to allow staff to draw on their skills and experience in improvising a response to the initial challenge and learning adaptively as the incident unfolded.

Objective: To document the organisational response of Furness General Hospital to the large outbreak of legionnaire's disease in April 2002 and assess the contribution made by the hospital's major incident plan. Method: Qualitative analysis of interview transcripts and written comments from some staff involved in the management of the incident. Documentary analysis of major incident plan and other written materials. Results: The incident posed considerable managerial and clinical problems and this paper describes how they were overcome. In particular, strategies for dealing with supply (of staff, beds, and resources) and managing demand (by liaising with primary care and the public) seem to have been successful. Many functions necessary for managing the incident were poorly dealt with in the plan, especially procedures for handling the news media and liaison with agencies outside the hospital.

There was also evidence that staff disregarded existing job and role boundaries and focused instead on tasks, working flexibly to ensure that these tasks were completed. Conclusions: Protracted major incidents pose particular management challenges and may benefit from an approach different from that set out in typical major incident plans.

Lee, Janet Lok Chun; Lo, Temmy Lee Ting

2018-01-01

(1) Background: An outdoor gym (OG) is environmental infrastructure built in a public open space to promote structured physical activity. The provision of OGs is increasingly seen as an important strategy to realize public health agendas promoting habitual physical activity. A systematic review was conducted to synthesize characteristics of OG and OG users’ experiences and perceptions in different cultural contexts; (2) Methods: Online searches of multidisciplinary databases were conducted in health, sport and recreation, and urban planning disciplines. Characteristics of OGs were synthesized by integrating evidence from quantitative, qualitative, and mix-methods studies. The experiences and perceptions of OG users from both qualitative data and survey responses were synthesized through framework analysis; (3) Results: Nine studies met the inclusion criteria (three quantitative studies, four mixed-methods studies, and two pure qualitative studies). None were excluded on the basis of quality. OGs mainly serve adult and older adult population groups. Their size, design, and instructional support vary across studies. The inclusion of functional types of equipment did not have a unified standard. Regarding experiences and perceptions of OGs, five major themes emerged: “health”, “social connectedness”, “affordable”, “support”, and “design and promotion”; (4) Conclusions: The OG characteristics synthesis guides the direction in further studies regarding exploration of design parameters. The qualitative and quantitative synthesis revealed that health was a central theme of users’ experiences. OGs are also spaces where community-dwellers can find social connectedness while participating in structured physical activity at no cost. Findings from this review create knowledge support for OG as environmental infrastructure for further research and facilitate the understanding of users’ experiences and perceptions of OGs in different cultural contexts.

A qualitative exploration of Malaysian cancer patients’ perceptions of cancer screening

PubMed Central

2013-01-01

Background Despite the existence of different screening methods, the response to cancer screening is poor among Malaysians. The current study aims to examine cancer patients’ perceptions of cancer screening and early diagnosis. Methods A qualitative methodology was used to collect in-depth information from cancer patients. After obtaining institutional ethical approval, patients with different types and stages of cancer from the three major ethnic groups (Malay, Chinese and Indian) were approached. Twenty semi-structured interviews were conducted. All interviews were audiotaped, transcribed verbatim, and translated into English for thematic content analysis. Results Thematic content analysis yielded four major themes: awareness of cancer screening, perceived benefits of cancer screening, perceived barriers to cancer screening, and cues to action. The majority of respondents had never heard of cancer screening before their diagnosis. Some participants reported hearing about mammogram and Pap smear tests but did not undergo screening due to a lack of belief in personal susceptibility. Those who had negative results from screening prior to diagnosis perceived such tests as untrustworthy. Lack of knowledge and financial constraints were reported as barriers to cancer screening. Finally, numerous suggestions were given to improve screening behaviour among healthy individuals, including the role of mass media in disseminating the message ‘prevention is better than cure’. Conclusions Patients’ narratives revealed some significant issues that were in line with the Health Belief Model which could explain negative health behaviour. The description of the personal experiences of people with cancer could provide many cues to action for those who have never encountered this potentially deadly disease, if incorporated into health promotion activities.

Weiner, Bryan J; Amick, Halle R; Lund, Jennifer L; Lee, Shoou-Yih Daniel; Hoff, Timothy J

2011-02-01

Over the past 10 years, the field of health services and management research has seen renewed interest in the use of qualitative research methods. This article examines the volume and characteristics of qualitative research articles published in nine major health services and management journals between 1998 and 2008. Qualitative research articles comprise 9% of research articles published in these journals. Although the publication rate of qualitative research articles has not kept pace with that of quantitative research articles, citation analysis suggests that qualitative research articles contribute comparably to the field's knowledge base. A wide range of policy and management topics has been examined using qualitative methods. Case study designs, interviews, and documentary sources were the most frequently used methods. Half of qualitative research articles provided little or no detail about key aspects the study's methods. Implications are discussed and recommendations are offered for promoting the publication of qualitative research.

This article reports and discusses how quantitative (physiological and behavioral) and qualitative methods are being combined in an open-label pilot feasibility study. The study evaluates safety, tolerability, and acceptability of a protocol to treat depression in HIV-infected individuals, using a 2-week block of transcranial direct current stimulation (tDCS) over the dorsolateral prefrontal cortex. Major depressive disorder (MDD) is the second most prevalent psychiatric disorder after substance abuse among HIV-positive adults, and novel antidepressant treatments are needed for this vulnerable population. The authors describe the challenges and contributions derived from different research perspectives and methodological approaches and provide a philosophical framework for combining quantitative and qualitative measurements for a fuller examination of the disorder. Four methodological points are presented: (1) the value of combining quantitative and qualitative approaches; (2) the need for context-specific measures when studying patients with medical and psychiatric comorbidities; (3) the importance of research designs that integrate physiological, behavioral, and qualitative approaches when evaluating novel treatments; and (4) the need to explore the relationships between biomarkers, clinical symptom assessments, patient self-evaluations, and patient experiences when developing new, patient-centered protocols. The authors conclude that the complexity of studying novel treatments in complex and new patient populations requires complex research designs to capture the richness of data that inform translational research.

Qualitative Study of Functional Groups and Antioxidant Properties of Soy-Based Beverages Compared to Cow Milk

2015-01-01

Soy-based beverages are a source of high quality proteins and balanced nutrients; they thus represent an alternative to milk in case of allergy to cow milk proteins or intolerance to lactose. In this research, antioxidant properties of soy-based beverages and UHT cow milk were studied. In addition, color parameters, by a quick and non-destructive methodology, were studied in order to verify a possible correlation with antioxidant properties and a qualitative analysis of the major functional groups undertaken by Fourier Transformed Infrared Spectroscopy (FTIR) on Attenuated Total Reflectance (ATR) was carried out. Extractable and hydrolysable polyphenols were studied in soy-based beverages. However, only the extractable fraction was studied in UHT milk, which was characterized by a small amount of polyphenols. All color parameters showed highly significant differences among soy-based beverages and between soy-based beverages and cow milk. FTIR-ATR spectra of soy-based beverages and cow milk showed several differences in the various regions depending on both the specific contribution of molecular groups and different food items.

Men appear to interpret people’s behaviors more sexually than do women. This finding, which has been replicated in scores of studies using a variety of methodological approaches, has been linked to important social concerns, including sexual assault and sexual harassment. This article provides a critical review of the published literature on gender differences in sexual intent perception, using selective examples to illustrate and summarize the field’s major constructs, methodologies, and empirical findings. Theoretical explanations for gender differences in sexual intent perceptions are reviewed. Finally, we highlight the field’s remaining issues and make several recommendations for future research directions. PMID:19763282

What motivates women to breastfeed in Lebanon: An exploratory qualitative analysis.

PubMed

BouDiab, Sarah; Werle, Carolina

2018-04-01

This exploratory qualitative study examined the influence of injunctive and descriptive norms on breastfeeding, a health-improving behaviour related to a highly committed personal decision. The research explores the different mechanisms through which social norms impact breastfeeding behaviour pre or post-adoption of breastfeeding practice. A qualitative approach was used by performing in-depth analysis of cross-sectional accounts of women in Lebanon contemplating adoption of breastfeeding practice and women who already breastfed. Interviews were also conducted with medical professionals, lactation specialists, and breastfeeding activists. On one hand, the attitude of the medical professionals and the government efforts are two mechanisms that stimulate the injunctive norms. On the other hand, the descriptive norms are defined by community attitude aggregated with societal beliefs and expectations on women's image and role in society. Both types of social norms are in constant interplay with personal norms and each type becomes more salient at different periods over time. The findings suggest that social norms are major determinants of breastfeeding behaviour. The influence of the type of social norm-descriptive or injunctive-on the decision to breastfeed varies according to the moment of life the mother is living. Theoretical and practical implications are discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

Meeting psychosocial needs for persons with dementia in home care services - a qualitative study of different perceptions and practices among health care providers.

PubMed

Hansen, Anette; Hauge, Solveig; Bergland, Ådel

2017-09-11

The majority of persons with dementia are home-dwelling. To enable these persons to stay in their own homes as long as possible, a holistic, individual and flexible care is recommended. Despite a requirement for meeting psychological, social and physical needs, home care services seem to focus on patients' physical needs. Accordingly, the aim of this study was to explore how the psychosocial needs of home-dwelling, older persons with dementia were perceived, emphasized and met by home care services. A descriptive, qualitative approach was used. Data were collected through semi-structured focus group interviews with 24 health care providers in home care services from four municipalities. Data were analysed using systematic text condensation. This study showed major differences in how health care providers perceived the psychosocial needs of older home-dwelling persons with dementia and how they perceived their responsibilities for meeting those psychosocial needs. The differences in the health care providers' perceptions seemed to significantly influence the provided care. Three co-existing logics of care were identified: the physical need-oriented logic, the renouncement logic and the integrated logic. The differences in how health care providers perceived the psychosocial needs of persons with dementia and their responsibilities for meeting those needs, influenced how the psychosocial needs were met. These differences indicates a need for a clarification of how psychosocial needs should be conceptualized and who should be responsible for meeting these needs. Further, increased competence and increased consciousness of psychosocial needs and how those needs can be met, are essential for delivering high-quality holistic care that enables persons with dementia to live in their own home for as long as possible.

Sex and gender differences in pain and analgesia.

PubMed

Mogil, Jeffrey S; Bailey, Andrea L

2010-01-01

It is a clinical reality that women make up the large majority of chronic pain patients, and there is now consensus from laboratory experiments that when differences are seen, women are more sensitive to pain than men. Research in this field has now begun to concentrate on finding explanations for this sex difference. Although sex differences in sociocultural, psychological, and experiential factors likely play important roles, evidence largely from animal studies has revealed surprisingly robust and often qualitative sex differences at low levels of the neuraxis. Although not yet able to affect clinical practice, the continued study of sex differences in pain may have important implications for the development of new analgesic strategies.

While vast opportunities for using qualitative methods exist within palliative care research, few studies provide practical advice for researchers and clinicians as a roadmap to identify and utilize such opportunities. To provide palliative care clinicians and researchers descriptions of qualitative methodology applied to innovative research questions relative to palliative care research and define basic concepts in qualitative research. Body: We describe three qualitative projects as exemplars to describe major concepts in qualitative analysis of early palliative care: (1) a descriptive analysis of clinician documentation in the electronic health record, (2) a thematic content analysis of palliative care clinician focus groups, and (3) a framework analysis of audio-recorded encounters between patients and clinicians as part of a clinical trial. This study provides a foundation for undertaking qualitative research within palliative care and serves as a framework for use by other palliative care researchers interested in qualitative methodologies.

A simple mathematical model of the carbon nanofiber catalytic growth process is presented. Two major types of the fiber-catalyst interface shapes have been identified and described having qualitatively different structure in the center of a nanofiber. Presently, we discuss that the appearance of the irregular structure in the nanofiber central area is a result of curved-interface-growth kinematics. We suggest the method to determine the phenomenological parameters of the developed model from experimental data.

Trauma affects children from all ethnicities, nationalities and socioeconomic backgrounds. However, indigenous children may experience trauma differently than their majority population peers due to traumatic histories of colonization and marginalization. This article reports on an exploratory qualitative study of how service providers in Western Montana and Northern Norway conceptualize Native American and Sámi children's experiences of trauma today. Findings reveal that participants relate current trauma experiences of indigenous youth to historical and intergenerational traumas.

2003-09-01

Assessment of livestock production constraints in the smallholder dairy systems in the western Kenya highlands was carried out using both qualitative and quantitative epidemiological methods. Rapid rural appraisals (qualitative) were conducted in rural and peri-urban areas. A cross-sectional survey (quantitative) was then conducted on a random sample of farms in the study area. Diseases, poor communication, lack of marketing of livestock produce, lack of artificial insemination services, and feed and water shortages during the dry season were identified as the major constraints to cattle production in both areas. Tick borne diseases (especially East Coast fever) were identified as the major constraint to cattle production. Qualitative methods were found to be more flexible and cheaper than the quantitative methods by a ratio of between 2.19-2.0. The two methods were found to complement each other. Qualitative studies could be applied in preliminary studies before initiating more specific follow up quantitative studies.

Patients’ subjective concepts about primary healthcare utilisation: the study protocol of a qualitative comparative study between Norway and Germany

PubMed Central

Herrmann, Wolfram J; Haarmann, Alexander; Flick, Uwe; Bærheim, Anders; Lichte, Thomas; Herrmann, Markus

2013-01-01

Background In Germany, utilisation of ambulatory healthcare services is high compared with other countries: While a study based on the process data of German statutory health insurances showed an average of 17.1 physician-patient-contacts per year, the comparable figure for Norway is about five. The usual models of healthcare utilisation, such as Rosenstock's Health Belief Model and Andersen's Behavioural Model, cannot explain these differences adequately. Organisational factors of the healthcare system, such as gatekeeping, do not explain the magnitude of the differences. Our hypothesis is that patients’ subjective concepts about primary healthcare utilisation play a major role in explaining different healthcare utilisation behaviour in different countries. Hence, the aim of this study is to explore these subjective concepts comparatively, between Germany and Norway. Methods/design With that aim in mind, we chose a comparative qualitative study design. In Norway and Germany, we are going to interview 20 patients each with qualitative episodic interviews. In addition, we are going to conduct participant observation in four German and four Norwegian primary care practices. The data will be analysed by thematic coding. Using selected categories, we are going to conduct comparative case and group analyses. Ethics and dissemination The study adheres to the Declaration of Helsinki. All interviewees will sign informed consent forms and all patients will be observed during consultation. Strict rules for data security will apply. Developed theory and policy implications are going to be disseminated by a workshop, presentations for experts and laypersons and publications. PMID:23794555

Determinants of energy efficiency across countries

NASA Astrophysics Data System (ADS)

Yao, Guolin

With economic development, environmental concerns become more important. Economies cannot be developed without energy consumption, which is the major source of greenhouse gas emissions. Higher energy efficiency is one means of reducing emissions, but what determines energy efficiency? In this research we attempt to find answers to this question by using cross-sectional country data; that is, we examine a wide range of possible determinants of energy efficiency at the country level in an attempt to find the most important causal factors. All countries are divided into three income groups: high-income countries, middle-income countries, and low-income countries. Energy intensity is used as a measurement of energy efficiency. All independent variables belong to two categories: quantitative and qualitative. Quantitative variables are measures of the economic conditions, development indicators and energy usage situations. Qualitative variables mainly measure political, societal and economic strengths of a country. The three income groups have different economic and energy attributes. Each group has different sets of variables to explain energy efficiency. Energy prices and winter temperature are both important in high-income and middle-income countries. No qualitative variables appear in the model of high-income countries. Basic economic factors, such as institutions, political stability, urbanization level, population density, are important in low-income countries. Besides similar variables, such as macroeconomic stability and index of rule of law, the hydroelectricity share in total electric generation is also a driver of energy efficiency in middle-income countries. These variables have different policy implications for each group of countries.

2014-01-01

Background: Infertility is a major life event that brings about social and psychological problems. The type and rate these problems in the context of socio-cultural of different geographical areas and sex of people is different. Objective: The aim of this qualitative study was to explain the psychological consequences of infertility in Iranian infertile women seeking treatment. Materials and Methods: This qualitative study was done using qualitative content analysis on 25 women affected by primary and secondary infertility with no surviving children in 2012. They were purposefully selected with maximum sample variation from a large Fertility Health Research Center in Tehran, Iran. Data were collected using 32 semi-structured interviews and analyzed by the conventional content analysis method. Results: The findings of this study include four main themes: 1. Cognitive reactions of infertility (mental engagement; psychological turmoil). 2. Cognitive reactions to therapy process (psychological turmoil; being difficult to control in some situations; reduced self-esteem; feelings of failure). 3. Emotional-affective reactions of infertility (fear, anxiety and worry; loneliness and guilt; grief and depression; regret). 4. Emotional-affective reactions to therapy process (fear, anxiety and worry; fatigue and helplessness; grief and depression; hopelessness). Conclusion: This study revealed that Iranian infertile women seeking treatment face several psychological-emotional problems with devastating effects on the mental health and well-being of the infertile individuals and couples, while the infertility is often treated as a biomedical issue in Iranian context with less attention on the mental-emotional, social and cultural aspects.

Women from different backgrounds and cultures are at risk of domestic violence. Disclosing the abusive experience and seeking help is not straightforward and easy and might be a complicated and long-term process. Muslim women, like other groups of women, may face various barriers to disclose abusive relationships and for seeking help. Some of the barriers may be common for the majority of Muslim women in different contexts, while others might be related to women's situations and the wider society they live. To identify these barriers and make recommendations for future studies, this article reviews related papers conducted in both Muslim-majority and non-Muslim-majority countries. A critical systematic review of the literature was conducted for identifying Muslim women's barriers in disclosing abuse and seeking help. Twenty-one studies met the inclusion criteria. The main identified barriers are discussed into under four themes: social context, family context, individual factors, and expectations of service providers. Although the researchers tried to investigate various barriers in seeking help, many of them have not focused on structural obstacles. Besides, in many Muslim-majority countries, the issue has not been explored. Therefore, the results of the current article will not apply to those countries. Recommendation for future research comprises more qualitative research compatible with the women's cultures and backgrounds in different societies, focusing more on structural and cultural factors to explore and find women's barriers to seek help.

Harmonic dissection versus electrocautery in breast surgery in regional Victoria.

Harmonic instruments are an alternative tool for surgical dissection. The aim of this study is to evaluate differences in clinical outcomes relating to harmonic dissection when compared with electrocautery in patients undergoing major breast surgery in a regional centre over a 3-year period. Retrospective chart analysis was conducted of 52 patients undergoing major breast surgery for carcinoma or ductal carcinoma in situ by a single surgeon in a regional centre from May 2008 to January 2011. Analysis involved the extraction of qualitative data relating to patient demographics, surgery type and specimen histopathology. Quantitative data were extracted relating to duration of surgery, duration of patient-controlled analgesia (PCA) use, length of hospital admission, drainage output and presence of infection, haematoma or seroma. Fifty-two patients underwent major breast surgery; harmonic dissection n = 32 and electrocautery n = 20. The two groups were comparable. There was no significant difference identified relating the outcome measures. The median operative duration was shorter in the harmonic dissection group, however, was not of statistical significance. No significant difference was identified between groups relating to length of inpatient stay, duration of PCA use and total volume wound drainage and total days of drainage. Incidence of seroma and infection in the groups was not significantly different. The harmonic dissection is safe and effective in major breast surgery. The study did not demonstrate any clinical advantage from the use of harmonic dissection in major breast surgery compared with electrocautery, nor was there any difference in the complication rates measured. © 2014 Royal Australasian College of Surgeons.

With growing interest in promoting skills related to the scientific process, we studied performance in solving ill-defined problems demonstrated by graduating biochemistry majors at a public, minority-serving university. As adoption of techniques for facilitating the attainment of higher-order learning objectives broadens, so too does the need to appropriately measure and understand student performance. We extended previous validation of the Individual Problem Solving Assessment (IPSA) and administered multiple versions of the IPSA across two semesters of biochemistry courses. A final version was taken by majors just before program exit, and student responses on that version were analyzed both quantitatively and qualitatively. This mixed-methods study quantifies student performance in scientific problem solving, while probing the qualitative nature of unsatisfactory solutions. Of the five domains measured by the IPSA, we found that average graduates were only successful in two areas: evaluating given experimental data to state results and reflecting on performance after the solution to the problem was provided. The primary difficulties in each domain were quite different. The most widespread challenge for students was to design an investigation that rationally aligned with a given hypothesis. We also extend the findings into pedagogical recommendations. PMID:29180350

Previous studies indicated that HC Blue 1 induced heptocellular carcinomas in B6C3F1 mice whereas the structurally similar nitroaromatic amine HC Blue 2 did not. In an attempt to elucidate the biochemical mechanisms responsible for their different carcinogenic potencies, comparative metabolism and genetic toxicity studies were undertaken. Eighteen-hour urinary recovery of administered radioactivity was equivalent for both compounds following oral gavage (100 mg/kg) in female B6C3F1 mice. By HPLC analysis, HC Blue 1 yielded 3 major polar metabolite peaks, one of which was susceptible to glucuronidase. In vivo metabolism of HC Blue 2 yielded a single major metabolite peak which was not hydrolyzed by glucuronidase. Metabolism by B6C3F1 mouse hepatocytes yielded metabolite profiles which were qualitatively similar to the profiles observed after in vivo metabolism. HC Blue 1 was metabolized by hepatocytes at approximately twice the rate of HC Blue 2. Cytogenetic evaluations of mouse hepatocytes after in vitro treatment indicated HC Blue 1 was more potent than HC Blue 2 in inducing chromosomal aberrations while both chemicals showed weak activity for inducing sister-chromatid exchanges. Furthermore, in the V79 cell metabolic cooperation assay, HC Blue 1, but not HC Blue 2, inhibited cell-to-cell communication suggesting a non-genotoxic activity may be present for HC Blue 1. It is concluded that qualitative and quantitative differences exist in the metabolism of these compounds and that genotoxic as well as nongenotoxic effects may contribute to their different carcinogenic potencies.

Undernutrition and low women's status persist as major development obstacles in South Asia and specifically, Nepal. Multi-sectoral approaches, including nutrition-sensitive agriculture, are potential avenues for further reductions in undernutrition. Although evidence is growing, many questions remain regarding how gender mediates the translation of agricultural production activities into nutritional benefit. In this study, we examined how gender influences the pathway from agricultural production to improved income and control of income, with a focus on five domains of empowerment: decision-making power, freedom of mobility, social support, workload and time, and self-efficacy. For this, we conducted a qualitative retrospective assessment (N = 10 FGDs) among 73 beneficiary women of a nutrition-sensitive agriculture programme implemented from 2008 to 2012 in two districts of Nepal-Baitadi and Kailali. We found that women reported increased decision-making power, new knowledge and skills, increased recognition by their family members of their new knowledge and contributions, and self-efficacy as farmers and sellers, whereas workload and time were the most consistent constraints noted. We also found that each empowerment domain operated differently at different stages of the pathway, sometimes representing barriers and at other times, opportunities and that the interconnectedness of the domains made them difficult to disentangle in practice. Finally, there were major contextual differences for some domains (e.g., freedom of mobility) between the two districts. Future policies and programmes need to include in-depth formative research to ensure that interventions address context-specific gender and social norms to maximise programmatic opportunities to achieve desired results. © 2018 John Wiley & Sons Ltd.

Participation in introductory biology laboratories: An integrated assessment based on surveys, behavioral observations, and qualitative interviews

NASA Astrophysics Data System (ADS)

Russell, Connie Adelle

Scope and method of study. The purpose of this study was to evaluate the effect of gender, major, and prior knowledge of and attitude toward biology on participation in introductory biology laboratories. Subjects for this study were 3,527 students enrolled in college-level introductory biology courses. During the study, three introductory courses were replaced with one mixed-majors course. The new course adopted a different pedagological approach from the previous courses in that an inquiry-based approach was used in lectures and laboratories. All subjects completed a survey that measured content knowledge using the NABT/NSTA High School Biology Examination Version 1990 and attitude using Russell and Hollander's Biology Attitude Scale. I used and discuss the merits of using ethological methods and data collection software, EthoScribeTM (Tima Scientific) to collect behavioral data from 145 students. I also evaluated participation using qualitative interviews of 30 students. I analyzed content knowledge and attitude data using ANOVA and Pearson correlation, and behavioral data using Contingency Table Analysis. I analyzed interviews following methods outlined by Rubin and Rubin. Findings. Course style and gender were the most useful variables in distinguishing differences among groups of students with regard to attitude, content knowledge, and participation in laboratories. Attitude toward biology and achievement measured by the surveys were found to be positively correlated; however, gender, major, class standing, course style and interactions between these variables also had effects on these variables. I found a positive association among attitude, achievement and participation in hands-on activities in laboratories. Differences in participation also were associated group type. In a traditional introductory biology course, females in single-gender groups, gender-equal, or groups in which females were the majority spent more time performing hands-on science-related activities than did females in groups in which they were the minority. Conversely, males in mixed-gender groups spent more time performing hands-on activities than did males in single-gender groups. Both sexes participated equally in laboratories taught in an inquiry-based style.

Owens, T.; Ungers, L.; Briggs, T.

1980-08-01

The purpose of this study is to estimate both quantitatively and qualitatively, the worker and societal risks attributable to four photovoltaic cell (solar cell) production processes. Quantitative risk values were determined by use of statistics from the California semiconductor industry. The qualitative risk assessment was performed using a variety of both governmental and private sources of data. The occupational health statistics derived from the semiconductor industry were used to predict injury and fatality levels associated with photovoltaic cell manufacturing. The use of these statistics to characterize the two silicon processes described herein is defensible from the standpoint that many ofmore » the same process steps and materials are used in both the semiconductor and photovoltaic industries. These health statistics are less applicable to the gallium arsenide and cadmium sulfide manufacturing processes, primarily because of differences in the materials utilized. Although such differences tend to discourage any absolute comparisons among the four photovoltaic cell production processes, certain relative comparisons are warranted. To facilitate a risk comparison of the four processes, the number and severity of process-related chemical hazards were assessed. This qualitative hazard assessment addresses both the relative toxicity and the exposure potential of substances in the workplace. In addition to the worker-related hazards, estimates of process-related emissions and wastes are also provided.« less

Tobin, Kenneth; Fraser, Barry J.

In order to provide a refreshing alternative to the majority of research reports, which malign science education and highlight its major problems and shortcomings, a series of case studies of exemplary practice was initiated to provide a focus on the successful and positive facets of schooling. The major data-collection approach was qualitative and involved 13 researchers in hundreds of hours of intensive classroom observation involving 20 exemplary teachers and a comparison group of nonexemplary teachers. A distinctive feature of the methodology was that the qualitative information was complemented by quantitative information obtained from the administration of questionnaires assessing student perceptions of classroom psychosocial environment. The major trends were that exemplary science teachers (1) used management strategies that facilitated sustained student engagement, (2) used strategies designed to increase student understanding of science, (3) utilized strategies that encouraged students to participate in learning activities, and (4) maintained a favorable classroom learning environment.

Clinical methods to identify responders to oral appliance (OA) therapy for obstructive sleep apnoea (OSA) are needed. Awake nasopharyngoscopy during mandibular advancement, with image capture and subsequent processing and analysis, may predict treatment response. A qualitative assessment of awake nasopharyngoscopy would be simpler for clinical practice. We aimed to determine if a qualitative classification system of nasopharyngoscopic observations reflects treatment response. OSA patients were recruited for treatment with a customised two-piece OA. A custom scoring sheet was used to record observations of the pharyngeal airway (velopharynx, oropharynx, hypopharynx) during supine nasopharyngoscopy in response to mandibular advancement and performance of the Müller manoeuvre. Qualitative scores for degree (< 25%, 25-50%, 50-75%, > 75%), collapse pattern (concentric, anteroposterior, lateral) and diameter change (uniform, anteroposterior, lateral) were recorded. Treatment outcome was confirmed by polysomnography after a titration period of 14.6 ± 9.8 weeks. Treatment response was defined as (1) Treatment AHI < 5, (2) Treatment AHI < 10 plus > 50% AHI reduction and (3) > 50% AHI reduction. Eighty OSA patients (53.8% male) underwent nasopharyngoscopy. The most common naspharyngoscopic observation with mandibular advancement was a small (< 50%) increase in velopharyngeal lateral diameter (37.5%). The majority of subjects (72.5%) were recorded as having > 75% velopharyngeal collapse on performance of the Müller manoeuvre. Mandibular advancement reduced the observed level of pharyngeal collapse at all three pharyngeal regions (p < 0.001). None of the nasopharyngoscopic qualitative scores differed between responder and non-responder groups. Qualitative assessment of awake nasopharyngoscopy appears useful for assessing the effect of mandibular advancement on upper airway collapsibility. However, it is not sensitive enough to predict oral appliance treatment outcome.

A Systematic Review of Patients’ Experiences in Communicating with Primary Care Physicians: Intercultural Encounters and a Balance between Vulnerability and Integrity

Communication difficulties persist between patients and physicians. In order to improve care, patients’ experiences of this communication must be understood. The main objective of this study is to synthesize qualitative studies exploring patients’ experiences in communicating with a primary care physician. A secondary objective is to explore specific factors pertaining to ethnic minority or majority patients and their influence on patients’ experiences of communication. Pertinent health and social sciences electronic databases were searched systematically (PubMed, Cinahl, PsychNet, and IBSS). Fifty-seven articles were included in the review on the basis of being qualitative studies targeting patients’ experiences of communication with a primary care physician. The meta-ethnography method for qualitative studies was used to interpret data and the COREQ checklist was used to evaluate the quality of included studies. Three concepts emerged from analyses: negative experiences, positive experiences, and outcomes of communication. Negative experiences related to being treated with disrespect, experiencing pressure due to time constraints, and feeling helpless due to the dominance of biomedical culture in the medical encounter. Positive experiences are attributed to certain relational skills, technical skills, as well as certain approaches to care privileged by the physician. Outcomes of communication depend on patients’ evaluation of the consultation. Four categories of specific factors exerted mainly a negative influence on consultations for ethnic minorities: language barriers, discrimination, differing values, and acculturation. Ethnic majorities also raised specific factors influencing their experience: differing values and discrimination. Findings of this review are limited by the fact that more than half of the studies did not explore cultural aspects relating to this experience. Future research should address these aspects in more detail. In conclusion, all patients seemed to face additional cultural challenges. Findings provide a foundation for the development of tailored interventions to patients’ preferences, thus ensuring more satisfactory experiences. Health care providers should be sensitive to specific factors (cultural and micro-cultural) during all medical encounters. PMID:26440647

Military fathers endure repeated separations from their children. In this qualitative study we describe military fathers' range of involvement with their children, paying special attention to the implications of deployment separation and reintegration. We discuss father involvement using three overlapping major domains of functioning: cognitive, affective, and behavioral. Additionally, we consider how types of father involvement differ vis-à-vis child age. Data were gathered via focus groups conducted with 71 fathers at 14 U.S. military installations. Descriptions of involvement were rich and varied. Involvement with children was a major concern for fathers, despite or perhaps because of the challenges of military careers. We discuss factors that help explain variations in involvement and offer insights about the conceptualization of father involvement for occupations requiring prolonged absences from home.

BACKGROUND Leishmania major is an Old World species causing cutaneous leishmaniasis and is transmitted by Phlebotomus papatasi and Phlebotomus duboscqi. In Brazil, two isolates from patients who never left the country were characterised as L. major-like (BH49 and BH121). Using molecular techniques, these isolates were indistinguishable from the L. major reference strain (FV1). OBJECTIVES We evaluated the lipophosphoglycans (LPGs) of the strains and their behaviour in Old and New World sand fly vectors. METHODS LPGs were purified, and repeat units were qualitatively evaluated by immunoblotting. Experimental in vivo infection with L. major-like strains was performed in Lutzomyia longipalpis (New World, permissive vector) and Ph. papatasi (Old World, restrictive or specific vector). FINDINGS The LPGs of both strains were devoid of arabinosylated side chains, whereas the LPG of strain BH49 was more galactosylated than that of strain BH121. All strains with different levels of galactosylation in their LPGs were able to infect both vectors, exhibiting colonisation of the stomodeal valve and metacyclogenesis. The BH121 strain (less galactosylated) exhibited lower infection intensity compared to BH49 and FV1 in both vectors. MAIN CONCLUSIONS Intraspecific variation in the LPG of L. major-like strains occur, and the different galactosylation levels affected interactions with the invertebrate host.

African-American males in computer science---Examining the pipeline for clogs

NASA Astrophysics Data System (ADS)

Stone, Daryl Bryant

The literature on African-American males (AAM) begins with a statement to the effect that "Today young Black men are more likely to be killed or sent to prison than to graduate from college." Why are the numbers of African-American male college graduates decreasing? Why are those enrolled in college not majoring in the science, technology, engineering, and mathematics (STEM) disciplines? This research explored why African-American males are not filling the well-recognized industry need for Computer Scientist/Technologists by choosing college tracks to these careers. The literature on STEM disciplines focuses largely on women in STEM, as opposed to minorities, and within minorities, there is a noticeable research gap in addressing the needs and opportunities available to African-American males. The primary goal of this study was therefore to examine the computer science "pipeline" from the African-American male perspective. The method included a "Computer Science Degree Self-Efficacy Scale" be distributed to five groups of African-American male students, to include: (1) fourth graders, (2) eighth graders, (3) eleventh graders, (4) underclass undergraduate computer science majors, and (5) upperclass undergraduate computer science majors. In addition to a 30-question self-efficacy test, subjects from each group were asked to participate in a group discussion about "African-American males in computer science." The audio record of each group meeting provides qualitative data for the study. The hypotheses include the following: (1) There is no significant difference in "Computer Science Degree" self-efficacy between fourth and eighth graders. (2) There is no significant difference in "Computer Science Degree" self-efficacy between eighth and eleventh graders. (3) There is no significant difference in "Computer Science Degree" self-efficacy between eleventh graders and lower-level computer science majors. (4) There is no significant difference in "Computer Science Degree" self-efficacy between lower-level computer science majors and upper-level computer science majors. (5) There is no significant difference in "Computer Science Degree" self-efficacy between each of the five groups of students. Finally, the researcher selected African-American male students attending six primary schools, including the predominately African-American elementary, middle and high school that the researcher attended during his own academic career. Additionally, a racially mixed elementary, middle and high school was selected from the same county in Maryland. Bowie State University provided both the underclass and upperclass computer science majors surveyed in this study. Of the five hypotheses, the sample provided enough evidence to support the claim that there are significant differences in the "Computer Science Degree" self-efficacy between each of the five groups of students. ANOVA analysis by question and total self-efficacy scores provided more results of statistical significance. Additionally, factor analysis and review of the qualitative data provide more insightful results. Overall, the data suggest 'a clog' may exist in the middle school level and students attending racially mixed schools were more confident in their computer, math and science skills. African-American males admit to spending lots of time on social networking websites and emailing, but are 'dis-aware' of the skills and knowledge needed to study in the computing disciplines. The majority of the subjects knew little, if any, AAMs in the 'computing discipline pipeline'. The collegian African-American males, in this study, agree that computer programming is a difficult area and serves as a 'major clog in the pipeline'.

Low physical activity is a major health issue among Chinese Americans. This study explored Chinese-American children's physical activity behaviors and influencing factors. Twenty-five children of Chinese or Taiwanese descent were interviewed to understand their favorite sports or physical activities, physical activity environments, and influences on their physical activity. All were between the ages of 9 and 13. Interviews were transcribed and coded using thematic data analysis procedures. Major themes included: (1) team sports, particularly basketball, were commonly listed as favorite sports or activities; (2) physical activity occurred mostly at school or an after-school setting; and (3) family played a major role in physical activity. Some trends/differences were detected based on age, sex, and socioeconomic status. Interventions to promote physical activity among Chinese-American children should emphasize team sports and encourage physical activity in schools, but also explore ways to involves families outside of school.

Identifying mediating factors of moral reasoning in science education

NASA Astrophysics Data System (ADS)

Zeidler, Dana L.; Schafer, Larry E.

The purpose of this research was to examine how science content knowledge, moral reasoning ability, attitudes, and past experiences mediate the formation of moral judgments on environmental dilemmas. The study was conducted in two phases using environmental science majors and nonscience majors of college age. Phase One determined if environmental science majors exhibited higher levels of moral reasoning on nontechnical environmental social issues than on general social issues and examined the extent to which possible mediating factors accounted for differences in moral reasoning. Phase Two was qualitative in nature, the purpose of which was to observe and identify trends in conversations between subjects as to how certain mediating factors are revealed as people form moral judgments. The framework on which this study was constructed incorporates a progressive educational position; a position that views science education as being interdisciplinary, and a social means to a social end.

How Has Living with Intimate Partner Violence Affected the Work Situation? A Qualitative Study among Abused Women in Norway.

PubMed

Alsaker, Kjersti; Moen, Bente E; Baste, Valborg; Morken, Tone

A qualitative study was conducted among 18 abused women from different parts of Norway to explore what paid work means for women exposed to partner violence and how living with an abusive partner affected their working life. Based on systematic text condensation analyses of their experiences as described in individual and focus group interviews, the study's findings reveal two major themes. The first is about recovery and survival, and the other about the spillover of problems caused by a violent partner into paid work. Work was important to the women, as it represented time off from violence, contact with others who cared for them, and maintenance of self-esteem and self-confidence. Having their own money provided security and strengthened the belief that they could manage on their own. The spillover of intimate partner violence problems appeared through feelings of fear, shame and guilt at work.

Old Ideals and New Realities: The Changing Context of Adolescent Partnerships in Cebu, Philippines

The Philippines has experienced rapid sociodemographic changes in recent years, with implications for adolescents. This study combines quantitative and qualitative data from Metro Cebu to assess the timing and predictors of adolescent partnerships, as well as the context in which these partnerships are occurring. The majority of adolescents (54%) had premarital sex, though this pattern varied by gender. Wealthier, urban men, and women with less education and lower reported religiosity, were more likely to have premarital sex. Engagement in risk behaviors was predictive of premarital sex for both males and females. The qualitative data contextualize the circumstances under which adolescents engage in sex and form partnerships, and illustrate how sociocultural norms contribute to gender differences in partnership patterns. Given the ‘new’ realities of young Filipinos’ lives, targeted efforts to support adolescents’ transition to adulthood are needed to avert potentially adverse lifeevents. PMID:22587636

Recent epidemiological research on firefighters indicates an increased incidence of specific types of cancer. Intervention is needed in the fire service yet little is known about how firefighters perceive their cancer risk. Participant observation (150 h, n = 100) and focus group (n = 17) data were collected from 15 fire stations in South Florida. Firefighters had at least 3 years of experience, ranks included drivers, captains, lieutenants, and specialty captains, with a median age of 51 years. From the qualitative analysis, two major categories (direct and indirect factors) for cancer risks emerged based on participant notions of cancer risk and cancer prevention behaviors as they relate to firefighting. Firefighters perceive cancer risks as the result of performing essential job tasks and from indirect job factors related to being a firefighter. The two categories of cancer risks suggest different points of entry for intervention. © 2017 Wiley Periodicals, Inc.

Adult attention-deficit/hyperactivity disorder and nicotine use: a qualitative study of patient perceptions

PubMed Central

2014-01-01

Background Adult Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with high rates of comorbid substance use disorders, and cigarette smoking has a particularly high prevalence in this population. However, there is an ongoing debate as to whether this tobacco use is an attempt at “self-medication” or due to behavioral disinhibition. There is a surprising lack of qualitative studies that investigate the subjective perceptions of adults with ADHD regarding cigarette smoking. The present study was designed to fill this gap in the literature. Methods We recruited twelve adult patients with ADHD and comorbid tobacco use from our ADHD consultation service, an outpatient facility of the Zurich University Psychiatric Hospital. Subjects were interviewed using qualitative methodology, and Mayring's qualitative content analysis was used to evaluate findings. Results We identified two explanatory models linking ADHD and tobacco use: smoking as an attempt at self-medication and “smoking as a social behavior”. On one hand, subjects considered tobacco a therapeutic aid, reporting positive effects on “inner tension” and cognitive function, and noted possible antidepressant properties as well. On the other hand, subjects considered smoking to enhance social functioning and to have a positive impact on interpersonal relationships. The majority believed that stimulant medications offered only a transient decrease in patterns of tobacco use because their ability to reduce nicotine cravings wore off quickly. Others believed that stimulants had no effect or even reinforced cigarette use. Conclusions Participants had different views about the link between cigarette smoking and ADHD. While the majority thought of nicotine as a sort of therapy, viewing smoking as a way to self-medicate symptoms of ADHD, motivations for nicotine use were also related to self-image, desire to belong to a peer-group, and a drive to undermine perceived social norms. Ultimately, these findings can be used by clinicians to improve treatment alliance and collaboration. PMID:24885526

Today, postgraduate students experience a variety of stresses and anxiety in different situations of academic cycle. Stress and anxiety have been defined as a syndrome shown by emotional exhaustion and reduced personal goal achievement. This article addresses the causes and different strategies of coping with this phenomena by PhD students at Iranian Universities of Medical Sciences. The study was conducted by a qualitative method using conventional content analysis approach. Through purposive sampling, 16 postgraduate medical sciences PhD students were selected on the basis of theoretical sampling. Data were gathered through semistructured interviews and field observations. Six hundred fifty-four initial codes were summarized and classified into 4 main categories and 11 subcategories on the thematic coding stage dependent on conceptual similarities and differences. The obtained codes were categorized under 4 themes including "thesis as a major source of stress," "supervisor relationship," "socioeconomic problem," and "coping with stress and anxiety." It was concluded that PhD students experience stress and anxiety from a variety of sources and apply different methods of coping in effective and ineffective ways. Purposeful supervision and guidance can reduce the cause of stress and anxiety; in addition, coping strategy must be in a thoughtful approach, as recommended in this study.

Mequindox, 3-methyl-2-quinoxalinacetyl-1,4-dioxide, is a quinoxaline-N,N-dioxide used in veterinary medicine as a antibacterial in China. To gain an understanding of the interspecies differences in the metabolism of mequindox, comparative metabolite profiles were qualitatively and quantitatively carried out for the first time in rat, chicken and pig liver microsomes by high-performance liquid chromatography combined with hybrid ion trap/time-of-flight mass spectrometry. A total of 14 metabolites were characterized based on their accurate MS(2) spectra and known structure of mequindox. The in vitro metabolic pathways of mequindox in three species were proposed as N-->O group reduction, carbonyl reduction, N-->O group reduction followed by carbonyl reduction or methyl mono-hydroxylation. A metabolic pathway involving N-->O group reduction followed by acetyl group mono-hydroxylation in only chicken was also proposed. There was also quantitative species difference for mequindox metabolism in three species. 1-Desoxymequindox was the main metabolite in all species, but otherwise there were some qualitative interspecies differences in mequindox major metabolites. This work has revealed biotransformation characteristics of mequindox among different species, and moreover will further facilitate the explanations of the biological activities of mequindox in animals. 2010 John Wiley & Sons, Ltd.

Selective pressures imposed by herbivores are often positively correlated with investments that plants make in defense. Research based on the framework of an evolutionary arms race has improved our understanding of why the amount and types of defenses differ between plant species. However, plant species are exposed to different selective pressures during the life of a leaf, such that expanding leaves suffer more damage from herbivores and pathogens than mature leaves. We hypothesize that this differential selective pressure may result in contrasting quantitative and qualitative defense investment in plants exposed to natural selective pressures in the field. To characterize shifts in chemical defenses, we chose six species of Inga, a speciose Neotropical tree genus. Focal species represent diverse chemical, morphological, and developmental defense traits and were collected from a single site in the Amazonian rainforest. Chemical defenses were measured gravimetrically and by characterizing the metabolome of expanding and mature leaves. Quantitative investment in phenolics plus saponins, the major classes of chemical defenses identified in Inga, was greater for expanding than mature leaves (46% and 24% of dry weight, respectively). This supports the theory that, because expanding leaves are under greater selective pressure from herbivores, they rely more upon chemical defense as an antiherbivore strategy than do mature leaves. Qualitatively, mature and expanding leaves were distinct and mature leaves contained more total and unique metabolites. Intraspecific variation was greater for mature leaves than expanding leaves, suggesting that leaf development is canalized. This study provides a snapshot of chemical defense investment in a speciose genus of tropical trees during the short, few-week period of leaf development. Exploring the metabolome through quantitative and qualitative profiling enables a more comprehensive examination of foliar chemical defense investment.

An exploratory study examining the influence of translation on the validity and reliability of qualitative data in nursing research.

Although the complexity of undertaking qualitative research with non-English speaking informants has become increasingly recognized, few empirical studies exist which explore the influence of translation on the findings of the study. The aim of this exploratory study was therefore to examine the influence of translation on the reliability and validity of the findings of a qualitative research study. In-depth interviews were undertaken in Cantonese with a convenience sample of six women to explore their perceptions of factors influencing their uptake of Pap smears. Data analysis involved three stages. The first stage involved the translation and transcription of all the interviews into English independently by two translators as well as transcription into Chinese by a third researcher. The second stage involved content analysis of the three data sets to develop categories and themes and the third stage involved a comparison of the categories and themes generated from the Chinese and English data sets. Despite no significant differences in the major categories generated from the Chinese and English data, some minor differences were identified in the themes generated from the data. More significantly the results of the study demonstrated some important issues to consider when using translation in qualitative research, in particular the complexity of managing data when no equivalent word exists in the target language and the influence of the grammatical style on the analysis. In addition the findings raise questions about the significance of the conceptual framework of the research design and sampling to the validity of the study. The importance of using only one translator to maximize the reliability of the study was also demonstrated. In addition the author suggests the findings demonstrate particular problems in using translation in phenomenological research designs.

Access to and support for continuing professional education amongst Queensland nurses: 2004 and 2007.

PubMed

Hegney, Desley; Tuckett, Anthony; Parker, Deborah; Robert, Eley

2010-02-01

This paper reports on the findings of a prospective exploratory study related to nurses' self-reports of continuing professional education access and support. The data were gathered by two postal surveys undertaken in 2004 and 2007 each which sampled 3000 nurses of the 30,000 nurse members of the industrial body - Queensland Nurses' Union. The response rates were 44.9% and 39.7% for 2004 and 2007, respectively. Over 85% of the nurses reported they had access to continuing professional education activities. However, it is apparent that the majority of these activities are either partially or completely self-funded. Further, between 2004 and 2007 the amount of financial support provided by employers for continuing education and training activities has decreased significantly. While there were differences between 2004 and 2007, the major barrier to be able to attend continuing professional education were financial (could not afford the fee involved; could not afford to take unpaid leave to attend). Another major barrier in both 2004 and 2007 was having the time to undertake the activity. Analysis for differences between nurses in different geographical locations indicated that distance remains a major barrier for nurses in rural and remote areas. These quantitative findings were supported by the qualitative findings on nurses' work where 'education and training' was, overall, the fifth highest ranked issue requiring further attention.

Xie, Yan-ming; Liao, Xing

2008-07-01

It is not finally concluded how to standardize the use of qualitative research in the world. Qualitative researchers disagree with each other about this issue. As we know, there have been a large number of articles written in different ways about qualitative research due to the "flexibility", one of its features. Qualitative research is quite different from quantitative research which is easy to control its quality and quality assessment. A series of criteria has been set up for quantitative research. However qualitative research needs to be improved in these aspects, in which qualitative interviews are mostly used at home and abroad at present. Hence, it becomes an important and urgent issue for qualitative researchers to standardly control and assess the quality of qualitative interview.

Comparing the epistemological underpinnings of students' and scientists' reasoning about conclusions

NASA Astrophysics Data System (ADS)

Hogan, Kathleen; Maglienti, Mark

2001-08-01

This study examined the criteria that middle school students, nonscientist adults, technicians, and scientists used to rate the validity of conclusions drawn by hypothetical students from a set of evidence. The groups' criteria for evaluating conclusions were considered to be dimensions of their epistemological frameworks regarding how knowledge claims are justified, and as such are integral to their scientific reasoning. Quantitative and qualitative analyses revealed that the responses of students and nonscientists differed from the responses of technicians and scientists, with the major difference being the groups' relative emphasis on criteria of empirical consistency or plausibility of the conclusions. We argue that the sources of the groups' differing epistemic criteria rest in their different spheres of cultural practice, and explore implications of this perspective for science teaching and learning.

2009-07-01

In this article, as two researchers from different traditions in qualitative research (consensual qualitative research and grounded theory), the authors present their shared views on the critical elements of trustworthiness in qualitative data. In addition to making specific recommendations about the integrity of data, the balance between participant meaning and researcher interpretation, and clear communication and application of the findings, they identify ways in which these issues are difficult to negotiate within and across different qualitative approaches. The authors present examples from various qualitative studies, emphasize the need for a shared language to reduce confusion between qualitative traditions and with researchers from a more strictly quantitative orientation, and recommend particular approaches to establishing trustworthiness in qualitative research.

Impact of paediatric human immunodeficiency virus infection on children's and caregivers' daily functioning and well-being: a qualitative study.

2012-09-01

Human immunodeficiency virus (HIV) infection impacts not only upon the physical health of affected children, but also their psychosocial functions, family relationships and economical status. Caregivers are confronted with complex challenges related to the physical, emotional and financial demands of raising these children. The purpose of this study was to enhance our understanding of the impact of HIV disease on both children's and caregivers' well-being, using a qualitative inquiry approach. A total of 35 primary caregivers of HIV-infected children participated in in-depth interviews. The issues discussed included the major negative impacts on children's daily functioning and well-being, and the perceived caregiver/parental burden. Participants included parents (40%), grandparents (22.8%), other relatives (e.g. uncles, aunts) (34.3%) and one foster parent (2.8%). Qualitative analysis revealed that the major negative impacts of HIV/AIDS included physical symptoms, school performance and relationship changes. The major negative impacts on caregivers' well-being included acceptance of the diagnosis, dealing with the financial burden and keeping the diagnosis private. Approaches are needed to address these challenges by enhancing families' coping skills and building supportive networks. © 2011 Blackwell Publishing Ltd.

Childhood epilepsy is common in Africa. However, there are little data on the developmental and behavioral problems experienced by children living with epilepsy, especially qualitative data that capture community perceptions of the challenges faced by these children. Identifying these perceptions using qualitative approaches is important not only to help design appropriate interventions but also to help adapt behavioral tools that are culturally appropriate. We documented the description of these problems as perceived by parents and teachers of children with or without epilepsy. The study involved 70 participants. Data were collected using in-depth interviews and focus group discussions and were analyzed using NVIVO to identify major themes. Our analysis identified four major areas that are perceived to be adversely affected among children with epilepsy. These included internalizing and externalizing problems such as aggression, temper tantrums, and excessive crying. Additionally, developmental delay, especially cognitive deficits and academic underachievement, was also identified as a major problematic area. There is a need to supplement these findings with quantitative estimates and to develop psychosocial and educational interventions to rehabilitate children with epilepsy who have these difficulties.

Integrated care is the combination of different healthcare services with the goal to provide comprehensive, seamless, effective and efficient patient care. Assessing the experiences of healthcare professionals (HCPs) is an important aspect when evaluating integrated care strategies. The aim of this rapid review was to investigate if quantitative surveys used to assess HCPs' experiences with integrated care capture all the aspects highlighted as being important in qualitative research, with a view to informing future survey development. The review considered all types of health professionals in primary care, and hospital and specialist services, with a specific focus on the provision of integrated care aimed at improving the patient journey. PubMed, CINAHL and grey literature sources were searched for relevant surveys/program evaluations and qualitative research studies. Full text articles deemed to be of relevance to the review were appraised for methodological quality using abridged critical appraisal instruments from the Joanna Briggs Institute. Data were extracted from included studies using standardized data extraction templates. Findings from included studies were grouped into domains based on similarity of meaning. Similarities and differences in the domains covered in quantitative surveys and those identified as being important in qualitative research were explored. A total of 37 studies (19 quantitative surveys, 14 qualitative studies and four mixed-method studies) were included in the review. A range of healthcare professions participated in the included studies, the majority being primary care providers. Common domains identified from quantitative surveys and qualitative studies included Communication, Agreement on Clear Roles and Responsibilities, Facilities, Information Systems, and Coordination of Care and Access. Qualitative research highlighted domains identified by HCPs as being relevant to their experiences with integrated care that have not routinely being surveyed, including Workload, Clear Leadership/Decision-Making, Management, Flexibility of Integrated Care Model, Engagement, Usefulness of Integrated Care and Collaboration, and Positive Impact/Clinical Benefits/Practice Level Benefits. There were several domains identified from qualitative research that are not routinely included in quantitative surveys to assess health professionals' experiences of integrated care. In addition, the qualitative findings suggest that the experiences of HCPs are often impacted by deeper aspects than those measured by existing surveys. Incorporation of targeted items within these domains in the design of surveys should enhance the capture of data that are relevant to the experiences of HCPs with integrated care, which may assist in more comprehensive evaluation and subsequent improvement of integrated care programs.

Background Methamphetamine use has grown considerably in China in recent years. Information about perceptions of risk on methamphetamine is important to facilitate health promotion efforts. Methods Using both survey data and qualitative interview data, the authors evaluate the perceived risk of methamphetamine use among Chinese users using a mixed-methods approach. Through Respondent Driven Sampling, the authors recruited a sample of 303 methamphetamine users in Changsha, China. Results A majority (59.1%) perceive that infrequent methamphetamine use poses no risk to the user, while 11.2% perceive at least moderate risk for light use. A majority (56.7%) perceived at least moderate risk associated with regular methamphetamine use. Most (82.2%) also perceive methamphetamine to be easily obtainable. A path model indicates that perceived risk shapes intentions to use and expectations of future use, as does perceived availability. Qualitatively, while addiction was the most common risk discussed by users, they differed on whether they perceived the drug addictive. Other concerns raised by interviewees included impaired cognition, mental health problems, physical harm, and social dysfunction. Discussion While some users identify significant risks with methamphetamine, others do not perceive its use to be problematic. Collectively, these findings indicate that intervening upon perceptions of risk among Chinese methamphetamine users may be a means to influence intentions to use. PMID:24925820

2008-01-01

On observing how qualitative and quantitative studies are reported in the biomedical literature it becomes evident that, besides the virtual absence of the former, they are presented in different ways. Authors of qualitative studies seem to need almost invariably to explain why they choose a qualitative approach whereas that does not occur in quantitative studies. This paper takes Ludwik Fleck's comparative epistemology as a means of exploring those differences empirically, illustrating on the basis of two studies dealing with different aspects of biomedical practices how qualitative methods can elucidate a variety of questions pertaining to this field. The paper concludes presenting some structural characteristics of the biomedical field which on one hand, would not be explored properly without employing qualitative methods and, on the other hand, can help understanding the little value given to qualitative techniques in this area.

Principles of Quantitative MR Imaging with Illustrated Review of Applicable Modular Pulse Diagrams.

Mills, Andrew F; Sakai, Osamu; Anderson, Stephan W; Jara, Hernan

2017-01-01

Continued improvements in diagnostic accuracy using magnetic resonance (MR) imaging will require development of methods for tissue analysis that complement traditional qualitative MR imaging studies. Quantitative MR imaging is based on measurement and interpretation of tissue-specific parameters independent of experimental design, compared with qualitative MR imaging, which relies on interpretation of tissue contrast that results from experimental pulse sequence parameters. Quantitative MR imaging represents a natural next step in the evolution of MR imaging practice, since quantitative MR imaging data can be acquired using currently available qualitative imaging pulse sequences without modifications to imaging equipment. The article presents a review of the basic physical concepts used in MR imaging and how quantitative MR imaging is distinct from qualitative MR imaging. Subsequently, the article reviews the hierarchical organization of major applicable pulse sequences used in this article, with the sequences organized into conventional, hybrid, and multispectral sequences capable of calculating the main tissue parameters of T1, T2, and proton density. While this new concept offers the potential for improved diagnostic accuracy and workflow, awareness of this extension to qualitative imaging is generally low. This article reviews the basic physical concepts in MR imaging, describes commonly measured tissue parameters in quantitative MR imaging, and presents the major available pulse sequences used for quantitative MR imaging, with a focus on the hierarchical organization of these sequences. © RSNA, 2017.

Cochrane systematic reviews have proven to be beneficial for decision making processes, both on a practitioner and a policy level, and there are current initiatives to extend the types of evidence used by them, including qualitative research. In this article we outline the major achievements of the Cochrane Qualitative and Implementation Methods Group. Although the Group has encountered numerous challenges in dealing with the evolution of qualitative evidence synthesis, both outside and within the Cochrane Collaboration, it has successfully responded to the challenges posed in terms of incorporating qualitative evidence in systematic reviews. The Methods Group will continue to advocate for more flexible and inclusive approaches to evidence synthesis in order to meet the exciting challenges and opportunities presented by mixed methods systematic reviews and reviews of complex interventions.

An important question for understanding the neural basis of problem solving is whether the regions of human prefrontal cortices play qualitatively different roles in the major cognitive restructuring required to solve difficult problems. However, investigating this question using neuroimaging faces a major dilemma: either the problems do not require major cognitive restructuring, or if they do, the restructuring typically happens once, rendering repeated measurements of the critical mental process impossible. To circumvent these problems, young adult participants were challenged with a one-dimensional Subtraction (or Nim) problem [Bouton, C. L. Nim, a game with a complete mathematical theory. The Annals of Mathematics, 3, 35-39, 1901] that can be tackled using two possible strategies. One, often used initially, is effortful, slow, and error-prone, whereas the abstract solution, once achieved, is easier, quicker, and more accurate. Behaviorally, success was strongly correlated with sex. Using voxel-based morphometry analysis controlling for sex, we found that participants who found the more abstract strategy (i.e., Solvers) had more gray matter volume in the anterior medial, ventrolateral prefrontal, and parietal cortices compared with those who never switched from the initial effortful strategy (i.e., Explorers). Removing the sex covariate showed higher gray matter volume in Solvers (vs. Explorers) in the right ventrolateral prefrontal and left parietal cortex.

Barriers and facilitators of adherence to antidepressants among outpatients with major depressive disorder: A qualitative study.

2017-01-01

One of the major challenges in treating major depressive disorder (MDD) is patients' non-adherence to medication. This study aimed to explore the barriers and facilitators of patients' adherence to antidepressants among outpatients with MDD. Semi-structured and individual in-depth interviews were conducted among patients with MDD who were taking antidepressants, in the psychiatric clinic of a government-run hospital in Malaysia. Participants were purposively sampled from different genders and ethnicities. Interviews were conducted using a validated topic guide, and responses were audio-recorded, transcribed verbatim, checked, and analyzed using the grounded theory approach. A total of 30 patients were interviewed. Forty different themes and sub-themes were identified which were conceptually divided into two distinct categories related to barriers and facilitators to adherence. The barriers were: patient-specific, medication-specific, healthcare provision and system, social-cultural, and logistics. The facilitators were: having insight, perceived health benefits, regular activities, patient-provider relationship, reminders, and social support networks. Patient-specific barriers and medication side effects were the major challenges for adhering to treatment. Perceived health benefits and having insight on the need for treatment were the most frequently cited facilitators. Targeted interventions should be developed to address the key barriers, and promote measures to facilitate adherence in this group of patients.

There is considerable evidence for cognitive dysfunction in schizophrenia and affective disorders, but the pattern of potential similarities or differences between diagnostic groups remains uncertain. The objective of this study was to conduct a quantitative review of studies on cognitive performance in schizophrenia and affective disorders. Relevant articles were identified through literature search in major databases for the period between January 1980 and December 2005. Meta-analytic treatment of the original studies revealed widespread cognitive deficits in patients with schizophrenia and affective disorders in intellectual ability and speed of information processing, in encoding and retrieval, rule discovery and in response generation and response inhibition. Differences between diagnostic groups were quantitative rather than qualitative.

Behavioural interventions for weight management in pregnancy: a systematic review of quantitative and qualitative data.

2011-06-22

There is a rising prevalence of excessive weight gain in pregnancy and an increasing number of pregnant women who are overweight or obese at the start of the pregnancy. Excessive weight gain during pregnancy is associated with adverse maternal and neonatal consequences and increases the risk of long-term obesity. Pregnancy therefore may be a key time to prevent excessive weight gain and improve the health of women and their unborn child. This systematic review sought to assess the effectiveness of behavioural interventions to prevent excessive weight gain in pregnancy and explore the factors that influence intervention effectiveness. We undertook a systematic review of quantitative and qualitative evidence. This included a meta-analysis of controlled trials of diet and physical activity interventions to prevent excessive weight gain during pregnancy and a thematic synthesis of qualitative studies that investigated the views of women on weight management during pregnancy. A thorough search of eleven electronic bibliographic databases, reference lists of included studies, relevant review articles and experts in the field were contacted to identify potentially relevant studies.Two independent reviewers extracted data. RevMan software was used to perform the meta-analyses. Qualitative data was subject to thematic analysis. Both quantitative and qualitative data were aligned using a matrix framework. Five controlled trials and eight qualitative studies were included. The overall pooled effect size found no significant difference in gestational weight gain amongst participants in the intervention group compared with the control group (mean difference -0.28 95% CI -0.64 to 0.09). The study designs, participants and interventions all varied markedly and there was significant heterogeneity within this comparison in the meta-analysis (I2 67%). Subgroup and sensitivity analysis did not identify contextual elements that influenced the effectiveness of the intervention.In a thematic analysis of the qualitative studies, three major themes emerged relating to women's views of weight management in pregnancy: pregnancy as a time of transition and change, conflicting and contradictory messages and a perceived lack of control. When the results of both quantitative and qualitative data were aligned it was clear that some of the barriers that women described in achieving healthy weight gain in pregnancy were not addressed by the interventions evaluated. This may have contributed to the limited effectiveness of the interventions. Despite intense and often tailored interventions there was no statistically significant effect on weight gain during pregnancy. Inadequate and often contradictory information regarding healthy weight management was reported by women in qualitative studies and this was addressed in the interventions but this in itself was insufficient to lead to reduced weight gain. Multiple types of interventions, including community based strategies are needed to address this complex health problem.

Guidelines about palliative sedation typically include recommendations to protect the well-being of relatives. The aim of this study was to systematically review evidence on the experiences of relatives with the practice of palliative sedation. PubMed, Embase, Web of Science, PsycINFO, and CINAHL were searched for empirical studies on relatives' experiences with palliative sedation. We investigated relatives' involvement in the decision-making and sedation processes, whether they received adequate information and support, and relatives' emotions. Of the 564 studies identified, 39 were included. The studies (30 quantitative, six qualitative, and three mixed methods) were conducted in 16 countries; three studies were based on relatives' reports, 26 on physicians' and nurses' proxy reports, seven on medical records, and three combined different sources. The 39 studies yielded a combined total of 8791 respondents or studied cases. Caregivers involved relatives in the decision making in 69%-100% of all cases (19 quantitative studies), and in 60%-100% of all cases, relatives were reported to have received adequate information (five quantitative studies). Only two quantitative studies reported on relatives' involvement in the provision of sedation. Despite the fact that the majority of relatives were reported to be comfortable with the use of palliative sedation (seven quantitative studies, four qualitative studies), several studies found that relatives were distressed by the use of sedation (five quantitative studies, five qualitative studies). No studies reported specifically about the support provided to the relatives. Relatives' experiences with palliative sedation are mainly studied from the perspective of proxies, mostly professional caregivers. The majority of relatives seems to be comfortable with the use of palliative sedation; however, they may experience substantial distress by the use of sedation.

Objective To describe the knowledge and beliefs of public policymakers on social inequalities in health and policies to reduce them in cities from different parts of Europe during 2010 and 2011. Design Phenomenological qualitative study. Setting 13 European cities. Participants 19 elected politicians and officers with a directive status from 13 European cities. Main outcome Policymaker's knowledge and beliefs. Results Three emerging discourses were identified among the interviewees, depending on the city of the interviewee. Health inequalities were perceived by most policymakers as differences in life-expectancy between population with economic, social and geographical differences. Reducing health inequalities was a priority for the majority of cities which use surveys as sources of information to analyse these. Bureaucracy, funding and population beliefs were the main barriers. Conclusions The majority of the interviewed policymakers gave an account of interventions focusing on the immediate determinants and aimed at modifying lifestyles and behaviours in the more disadvantaged classes. More funding should be put towards academic research on effective universal policies, evaluation of their impact and training policymakers and officers on health inequalities in city governments.

Much qualitative research is interview based, and this paper provides an outline of qualitative interview techniques and their application in medical settings. It explains the rationale for these techniques and shows how they can be used to research kinds of questions that are different from those dealt with by quantitative methods. Different types of qualitative interviews are described, and the way in which they differ from clinical consultations is emphasised. Practical guidance for conducting such interviews is given.

The aim of this study was to explore cultural differences in causal attributions and beliefs about heritability of major depressive disorder (MDD). Face-to-face interviews with Anglo-Celtic- and Chinese-Australians community members with a family history of MDD were conducted and subjected to a rigorous qualitative analysis, using the computer software NVivo. Sixteen Anglo-Celtic-Australians and 16 Chinese-Australians were interviewed. Both groups believed that a combination of genetic and environmental factors contributed to MDD, that stress was an important cause of MDD, and that coping factors were significant moderators of the impact of stress on MDD. Both cultural groups believed that the causes of MDD affecting multiple family members included a shared family environment and a "contagion effect", in addition to genetics. Unique to the Chinese-Australian group was the beliefs that parental pressures to exceed academically contributed to MDD; this cultural group also reported beliefs that depression was due to God's will or alternatively fate, which in turn was related to attributions to feng shui and auspicious dates. This study documented key culture-specific differences in beliefs about causes and inheritance of MDD; such differences have major implications for clinician-patient communication about genetic risk associated with having a family history of MDD.

The most widespread method for the treatment of donor milk is the Holder pasteurization (HoP). The available literature data show that HoP may cause degradation of some bioactive components. The aim of this study was to determine the effect of HoP on the protein profile of human milk (HM) using a GeLC-MS method, a proteomic approach and a promising technique able to offer a qualitative HM protein profile. HM samples were collected by standardized methods from 20 mothers carrying both preterm and term newborns. A aliquot of each sample was immediately frozen at -80 °C, whilst another one was Holder pasteurized and then frozen. All samples were then analyzed by GeLC-MS. The protein bands of interest were excised from the gel, digested with trypsin and identified by nano-HPLC-MS/MS analysis. The protein profile before and after HoP showed qualitative differences only in 6 samples out of 20, while in the remaining 14 no detectable differences were found. The differences interested only colostrums and transitional milk samples and regarded the decrease of the electrophoretic bands corresponding to alpha and beta-casein, tenascin, lactoferrin and immunoglobulin. In the majority of samples, HoP did not cause any modification, thereby preserving the biological activity of HM proteins.

Serum amyloid A (SAA) is a major acute phase protein in dogs. However, knowledge of qualitative properties of canine SAA and extent of its synthesis in extrahepatic tissues is limited. The aim of the study was to investigate expression of different SAA isoforms in serum and synovial fluid in samples obtained from dogs (n=16) suffering from different inflammatory or non-inflammatory conditions, which were either related or unrelated to joints. Expression of SAA isoforms was visualized by denaturing isoelectric focusing and Western blotting. Serum amyloid A was present in serum from all dogs with systemic inflammatory activity, and up to four major isoforms with apparent isoelectric points between 6.1 and 7.9 were identified. In synovial fluid from inflamed joints one or more highly alkaline SAA isoforms (with apparent isoelectric points above 9.3) were identified, with data suggesting local production of these isoforms in the canine inflamed joint.

Distinct gender roles influence gender inequality and build the foundation for gender-based violence. Violence against women is a major public health problem in all societies, and a violation of human rights. Prevalence surveys on gender-based violence have been published from Sri Lanka, but qualitative studies on men's perceptions are lacking. The aim of this study was to explore young educated Sri Lankan men's perceptions of violence against women. Seven focus-group discussions were held. Men at the end of their university studies were purposefully selected. A topic guide was used, covering various scenarios of violence against women. Qualitative content analysis was carried out. Four categories were developed through the analytic process: fixed gender roles - patriarchal values are accepted in society, female mobility control, and slowly changing attitudes; violence not accepted but still exists - sexual harassment exists everywhere, different laws for different people, female tolerance of violence, and men's right to punish; multiple factors cause violence - alcohol, violent behavior is inherited, violence culturally accepted, low education, and lack of communication; and prevention of violence against women - both parents must engage and socialize girls and boys equally, life skills education, premarital counselling, working places value clarification, and more women in politics and boards are suggested. Medical and management students, possible future male leaders of the country, have suggestions of prevention strategies in life skills to reduce gender-based violence and to increase knowledge of health consequences with the aim of changing attitudes.

``Physics with a Smile''-Explaining Phenomena with a Qualitative Problem-Solving Strategy

Various studies indicate that high school physics students and even college students majoring in physics have difficulties in qualitative understanding of basic concepts and principles of physics.1-5 For example, studies carried out with the Force Concept Inventory (FCI)1,6 illustrate that qualitative tasks are not easy to solve even at the college level. Consequently, "conceptual physics" courses have been designed to foster qualitative understanding, and advanced high school physics courses as well as introductory college-level courses strive to develop qualitative understanding. Many physics education researchers emphasize the importance of acquiring some qualitative understanding of basic concepts in physics as early as middle school or in the context of courses that offer "Physics First" in the ninth grade before biology or chemistry.7 This trend is consistent with the call to focus the science curriculum on a small number of basic concepts and ideas, and to instruct students in a more "meaningful way" leading to better understanding. Studies7-10 suggest that familiar everyday contexts (see Fig. 1) are useful in fostering qualitative understanding.

HIV and violence are two major public health problems increasingly shown to be connected and relevant to international mental health issues and HIV-related services. Qualitative research is important due to the dearth of literature on this association in developing countries, cultural influences on mental health syndromes and presentations, and the sensitive nature of the topic. The study presented in this paper sought to investigate the mental health issues of an HIV-affected population of women and children in Lusaka, Zambia, through a systematic qualitative study. Two qualitative methods resulted in the identification of three major problems for women: domestic violence (DV), depression-like syndrome, and alcohol abuse; and children: defilement, DV, and behavior problems. DV and sexual abuse were found to be closely linked to HIV and alcohol abuse. This study shows the local perspective of the overlap between violence and HIV. Results are discussed in relation to the need for violence and abuse to be addressed as HIV services are implemented in sub-Saharan Africa. PMID:16909070

Context A better understanding of why students leave an undergraduate athletic training education program (ATEP), as well as why they persist, is critical in determining the future membership of our profession. Objective To better understand how clinical experiences affect student retention in undergraduate ATEPs. Design Survey-based research using a quantitative and qualitative mixed-methods approach. Setting Three-year undergraduate ATEPs across District 4 of the National Athletic Trainers' Association. Patients or Other Participants Seventy-one persistent students and 23 students who left the ATEP prematurely. Data Collection and Analysis Data were collected using a modified version of the Athletic Training Education Program Student Retention Questionnaire. Multivariate analysis of variance was performed on the quantitative data, followed by a univariate analysis of variance on any significant findings. The qualitative data were analyzed through inductive content analysis. Results A difference was identified between the persister and dropout groups (Pillai trace = 0.42, F1,92 = 12.95, P = .01). The follow-up analysis of variance revealed that the persister and dropout groups differed on the anticipatory factors (F1,92 = 4.29, P = .04), clinical integration (F1,92 = 6.99, P = .01), and motivation (F1,92 = 43.12, P = .01) scales. Several themes emerged in the qualitative data, including networks of support, authentic experiential learning, role identity, time commitment, and major or career change. Conclusions A perceived difference exists in how athletic training students are integrated into their clinical experiences between those students who leave an ATEP and those who stay. Educators may improve retention by emphasizing authentic experiential learning opportunities rather than hours worked, by allowing students to take on more responsibility, and by facilitating networks of support within clinical education experiences.

Mental health literacy is the beliefs and knowledge about mental health issues and their remedies. Attitudes and beliefs of lay individuals about mental illness are shaped by personal knowledge about mental illness, knowing and interacting with someone living with mental illness, and cultural stereotypes. Mental health issues are increasing and are alarming in almost every part of the world, and hence compiling this review provides an opportunity to understand the different views regarding mental disorders and problems as well as to fill the gap in the published literature by focusing only on the belief system and perception of mental health problems among general population. The methodology involved a systematic review and the meta-synthesis method, which includes synthesizing published qualitative studies on mental health perception and beliefs. Fifteen relevant published qualitative and mixed-method studies, regarding the concept of mental health, were identified for meta-synthesis. All the themes of the selected studies were further analyzed to give a broader picture of mental health problems and their perceived causes and management. Only qualitative studies, not older than 2010, focusing on beliefs about, attitudes toward, and perceptions of mental health problems, causes, and treatments were included in this review. The findings are divided into four major categories, namely, 1) symptoms of mental health issues, 2) description of mental health issues, 3) perceived causes, and 4) preferred treatment and help-seeking behavior. Each category contains themes and subthemes based on published studies. The findings reveal multiple causes of, descriptions of, and treatment options for mental health problems, thereby providing insight into different help-seeking behaviors. Clarity is offered by highlighting cultural differences and similarities in mental health beliefs and perceptions about the causes of mental health problems. The implications of the studies and recommendations based on current findings are also discussed.

Cyclic polyalcohol composition of 80 natural wood samples from different botanical species, with the majority of them used in the oenology industry for aging purposes, has been studied by gas chromatography-mass spectrometry (GC-MS) after its conversion into their trimethylsilyloxime derivatives. Each botanical species showed a different and specific cyclic polyalcohol profile. Oak wood samples were characterized by the richness in deoxyinositols, especially proto-quercitol. Meanwhile, other botanical species showed a very low content of cyclic polyalcohols. The qualitative and quantitative study of cyclic polyalcohols was a useful tool to characterize and differentiate woods of different botanical origin to guarantee the authenticity of chips used in the wine-aging process. Monosaccharide composition was also analyzed, showing some quantitative differences among species, but cyclic polyalcohols were the compounds that revealed the main differentiation power.

Contextual Factors Related to Stereotype Threat and Student Success in Science Technology Engineering Mathematics Education: A Mixed Methods Study

NASA Astrophysics Data System (ADS)

Leker, Lindsey Beth

Stereotype threat is a widely researched phenomenon shown to impact performance in testing and evaluation situations (Katz, Roberts, & Robinson, 1965; Steele & Aronson, 1995). When related to gender, stereotype threat can lead women to score lower than men on standardized math exams (Spencer, Steele, & Quinn, 1999). Stereotype threat may be one reason women have lower enrollment in most science, technology, engineering, and mathematics (STEM) majors, hold a smaller number of STEM careers than men, and have a higher attrition rate in STEM professions (Hill, Corbet, & Rose, 2010; Picho & Brown 2011; Sorby & Baartmans, 2000). Most research has investigated stereotype threat using experiments yielding mixed results (Stoet & Geary, 2012). Thus, there is a need to explore stereotype threat using quantitative surveys and qualitative methods to examine other contextual factors that contribute to gender difference in STEM fields. This dissertation outlined a mixed methods study designed to, first, qualitatively explore stereotype threat and contextual factors related to high achieving women in STEM fields, as well as women who have failed and/or avoided STEM fields. Then, the quantitative portion of the study used the themes from the qualitative phase to create a survey that measured stereotype threat and other contextual variables related to STEM success and failure/avoidance. Fifteen participants were interviewed for the qualitative phase of the study and six themes emerged. The quantitative survey was completed 242 undergraduate participants. T-tests, correlations, regressions, and mediation analyses were used to analyze the data. There were significant relationships between stereotype threat and STEM confidence, STEM anxiety, giving up in STEM, and STEM achievement. Overall, this mixed methods study advanced qualitative research on stereotype threat, developed a much-needed scale for the measurement of stereotype threat, and tested the developed scale.

Objective Little is known about parent feeding practices with siblings. Because this is a new area of research, qualitative research is needed to understand parents’ perspectives about how they make decisions about feeding siblings and whether they adapt their feeding practices dependent on sibling characteristics such as weight status. The main objective of the current study was to describe parent feeding practices with siblings. Design Qualitative cross-sectional study with 88 parents with at least two siblings. Setting Parents were interviewed in their homes in Minneapolis/St. Paul Minnesota. Participants Parents were from racially/ethnically diverse (64% African American) and low-income households (77% earned < $35,000/yr.). Main Outcome Measure Parents’ perceptions of feeding practices with siblings. Analysis Qualitative interviews were coded using a hybrid deductive and inductive content analysis approach. Results Parents indicated that they used child food preferences, in-the-moment decisions, and planned meals when deciding how to feed siblings. Additionally, the majority of parents indicated that they managed picky eating by making one meal or giving some flexibility/leeway to siblings about having other food options. Furthermore, parents endorsed using different feeding practices (e.g., food restriction, portion control, pressure-to-eat, opportunities for healthful eating) with siblings dependent on child weight status or age/developmental stage. Conclusions and Implications Findings from the current study may inform future research regarding how to measure parent feeding practices with siblings in the home environment and the development of interventions tailored for families with multiple children in the home. Future quantitative research is needed to confirm these qualitative findings. PMID:27373864

The objective of this systematic review was to understand the current state of Ergonomics/Human Factors (E/HF) qualitative research in health care and to draw implications for future efforts. This systematic review identified 98 qualitative research papers published between January 2005 and August 2015 in the seven journals endorsed by the International Ergonomics Association with an impact factor over 1.0. The majority of the studies were conducted in hospitals and outpatient clinics, were focused on the work of formal health care professionals, and were classified as cognitive or organizational ergonomics. Interviews, focus groups, and observations were the most prevalent forms of data collection. Triangulation and data archiving were the dominant approaches to ensuring rigor. Few studies employed a formal approach to qualitative inquiry. Significant opportunities remain to enhance the use of qualitative research to advance systems thinking within health care.

Objectives To elicit sources of waste as viewed by hospital workers Design Qualitative study using photo-elicitation, an ethnographic technique for prompting in-depth discussion Setting U.S. academic tertiary care hospital Participants Physicians, nurses, pharmacists, administrative support personnel, administrators and respiratory therapists Methods A purposive sample of personnel at an academic tertiary care hospital was invited to take up to 10 photos of waste. Participants discussed their selections using photos as prompts during in-depth interviews. Transcripts were analyzed in an iterative process using grounded theory; open and axial coding was performed, followed by selective and thematic coding to develop major themes and sub-themes. Results Twenty-one participants (9 women, average number of years in field=19.3) took 159 photos. Major themes included types of waste and recommendations to reduce waste. Types of waste comprised four major categories: Time, Materials, Energy and Talent. Participants emphasized time wastage (50% of photos) over other types of waste such as excess utilization (2.5%). Energy and Talent were novel categories of waste. Recommendations to reduce waste included interventions at the micro-level (e.g. individual/ward), meso-level (e.g. institution) and macro-level (e.g., payor/public policy). Conclusions The waste hospital workers identified differed from previously described waste both in the types of waste described and the emphasis placed on wasted time. The findings of this study represent a possible need for education of hospital workers about known types of waste, an opportunity to assess the impact of novel types of waste described and an opportunity to intervene to reduce the waste identified.

Objective To explore how survey respondents perceived their experiences and the impact of participating in a survey, and to assess adverse consequences resulting from participation. Design Qualitative study involving purposefully selected participants who had participated in a household-based survey. Methods This qualitative study was nested within a survey that investigated the prevalence of gender-based violence perpetration and victimization with adult men and women in South Africa. 13 male- and 10 female-in-depth interviews were conducted with survey respondents. Results A majority of informants, without gender-differences, perceived the survey interview as a rare opportunity to share their adverse and or personal experiences in a 'safe' space. Gender-differences were noted in reporting perceptions of risks involved with survey participation. Some women remained fearful after completing the survey, that should breach of confidentiality or full survey content disclosure occur, they may be victimized by partners as a punishment for survey participation without men's approval. A number of informants generally discussed their survey participation with others. However, among women with interpersonal violence history or currently in abusive relationships, full survey content disclosure was done with fear; the partner responses were negative, and few women reported receiving threatening remarks but none reported being assaulted. In contrast no man reported adverse reaction by others. Informants with major life adversities reported that the survey had made them to relive the experiences causing them sadness and pain at the time. No informant perceived the survey as emotionally harmful or needed professional support because of survey questions. Rather the vast majority perceived benefit from survey participation. Conclusion Whilst no informant felt answering the survey questions had caused them emotional or physical harm, some were distressed and anxious, albeit temporarily. Research protocols need to put in place safeguards where appropriate so that this group receives support and protection. PMID:22558160

Defining drug use: a model for the integration of measures through the census tract.

1986-07-01

The nature and severity of drug use has been measured both directly and indirectly by various studies employing different indicators, although the majority of studies still tend to use single measures of drug use. The need to employ multiple measures in examining drug abuse is constrained by the fact that available data may have been collected through diverse methodologies and measured on different levels or units. The purpose of this study was to develop and test in Philadelphia a model using qualitatively different types of data integrated by the common geographic unit of a census tract. The types of data used included: archival data, key informant data, and survey data. Using this approach the paper examines the relationships of drug use measures to each other, to the social environment, and to drug market factors. Major findings of the analysis indicate that there are several independent measures of drug use as reflected in five composite indicators which differentiate behavioral activities or consequences of drug use. Moreover, heroin use indicators exhibit relationships with social-environmental characteristics and drug market factors which are different from those existing with amphetamine or synthetic drug use.

In this work, a self-made microplasma jet system was used to conduct the qualitation and quantitation of inactivation with Escherichia coli as the target bacteria. The logarithmic concentration and the size of antimicrobial rings served as the evaluation parameters, respectively. The effect of various parameters on inactivation effect was studied. The results showed that the majority of bacteria had been inactivated in 30 s. The inactivation effect enhanced and then weakened with the increase of air flow rate, and receded as the extension of treatment distance. The effect with different carrier gases showed as follows: oxygen > air > nitrogen > argon. Meanwhile, the effect of different components of microplasma was studied in the optimum conditions (The flow rate was 5 L/min; inactivation distance was 2 cm). The results showed that electrically neutral active species was the main factor of inactivation rather than heating effect, ultraviolet radiation and charged particles. Finally the experiments of thallus change proved that microplasma jet had etching effect on cell membrane. It also found that microplasma could degrade organic material like protein. Furthermore, the images of scanning electron microscope (SEM) revealed the change of cell morphology step by step in the whole process of inactivation.

[Recovery: systematic review of a concept].

2015-01-01

The concept of recovery has been described in papers as a state of psychic, physical and social recuperation of day-to-day functions. The scope of this article is to analyze the concepts of the term in different research methodologies and the paradigmatic evolution of the recovery concept. Systematic bibliographical research was conducted in the Pubmed database using the words "recovery + schizophrenia" limited to freely available full papers published in the previous two years. Nineteen papers were analyzed. The majority of the papers sought associations between characteristic data and recovery; few papers discussed the concept in a way to distinguish it from other words like cure or rehabilitation. Recovery as a state in which people with severe mental illness can feel like the creators of their own itinerary tend to be found in qualitative studies and in bibliographic reviews in which the meaning of recovery is not related to the lack of symptoms and tends to prioritize how participative the life of an individual can be despite the disease. Some quantitative studies detect this conceptual difference. In qualitative research there is an increase in the concept of recovery and in ways of promoting it.

The logarithmic concentration and the size of antimicrobial rings served as the evaluation parameters, respectively. The effect of various parameters on inactivation effect was studied. The results showed that the majority of bacteria had been inactivated in 30 s. The inactivation effect enhanced and then weakened with the increase of air flow rate, and receded as the extension of treatment distance. The effect with different carrier gases showed as follows: oxygen > air > nitrogen > argon. Meanwhile, the effect of different components of microplasma was studied in the optimum conditions (The flow rate was 5 L/min inactivation distance was 2 cm). The results showed that electrically neutral active species was the main factor of inactivation rather than heating effect, ultraviolet radiation and charged particles. Finally the experiments of thallus change proved that microplasma jet had etching effect on cell membrane. It also found that microplasma could degrade organic material like protein. Furthermore, the images of scanning electron microscope (SEM) revealed the change of cell morphology step by step in the whole process of inactivation.

Titration and hysteresis in epigenetic chromatin silencing

Epigenetic mechanisms of silencing via heritable chromatin modifications play a major role in gene regulation and cell fate specification. We consider a model of epigenetic chromatin silencing in budding yeast and study the bifurcation diagram and characterize the bistable and the monostable regimes. The main focus of this paper is to examine how the perturbations altering the activity of histone modifying enzymes affect the epigenetic states. We analyze the implications of having the total number of silencing proteins, given by the sum of proteins bound to the nucleosomes and the ones available in the ambient, to be constant. This constraint couples different regions of chromatin through the shared reservoir of ambient silencing proteins. We show that the response of the system to perturbations depends dramatically on the titration effect caused by the above constraint. In particular, for a certain range of overall abundance of silencing proteins, the hysteresis loop changes qualitatively with certain jump replaced by continuous merger of different states. In addition, we find a nonmonotonic dependence of gene expression on the rate of histone deacetylation activity of Sir2. We discuss how these qualitative predictions of our model could be compared with experimental studies of the yeast system under anti-silencing drugs.

Beck, Cheryl Tatano

2009-10-01

The ability to critique research is a valuable skill that is fundamental to a perioperative nurse's ability to base his or her clinical practice on evidence derived from research. Criteria differ for critiquing a quantitative versus a qualitative study (ie, statistics are evaluated in a quantitative study, but not in a qualitative study). This article provides on guidelines for assessing qualitative research. Excerpts from a published qualitative research report are summarized and then critiqued. Questions are provided that help evaluate different sections of a research study (eg, sample, data collection methods, data analysis).

How will we know "good" qualitative research when we see it? Beginning the dialogue in health services research.

PubMed

Devers, K J

1999-12-01

To lay the foundation for an explicit review and dialogue concerning the criteria that should be used to evaluate qualitative health services research. Clear criteria are critical for the discipline because they provide a benchmark against which research can be assessed. Existing literature in the social sciences and health services research, particularly in primary care and medicine. Traditional criteria for evaluating qualitative research are rooted in the philosophical perspective (positivism) most closely associated with quantitative research and methods. As a result, qualitative research and methods may not be used as frequently as they can be and research results generated from qualitative studies may not be disseminated as widely as possible. However, alternative criteria for evaluating qualitative research have been proposed that reflect a different philosophical perspective (post-positivism). Moreover, these criteria are tailored to the unique purposes for which qualitative research is used and the research designs traditionally employed. While criteria based on these two different philosophical perspectives have much in common, some important differences exist. The field of health services research must engage in a collective, "qualitative" process to determine which criteria to adopt (positivist or post-positivist), or whether some combination of the two is most appropriate. Greater clarity about the criteria used to evaluate qualitative research will strengthen the discipline by fostering a more appropriate and improved use of qualitative methods, a greater willingness to fund and publish "good" qualitative research, and the development of more informed consumers of qualitative research results.

Exploring the post-genomic world: differing explanatory and manipulatory functions of post-genomic sciences

Richard Lewontin proposed that the ability of a scientific field to create a narrative for public understanding garners it social relevance. This article applies Lewontin's conceptual framework of the functions of science (manipulatory and explanatory) to compare and explain the current differences in perceived societal relevance of genetics/genomics and proteomics. We provide three examples to illustrate the social relevance and strong cultural narrative of genetics/genomics for which no counterpart exists for proteomics. We argue that the major difference between genetics/genomics and proteomics is that genomics has a strong explanatory function, due to the strong cultural narrative of heredity. Based on qualitative interviews and observations of proteomics conferences, we suggest that the nature of proteins, lack of public understanding, and theoretical complexity exacerbates this difference for proteomics. Lewontin's framework suggests that social scientists may find that omics sciences affect social relations in different ways than past analyses of genetics. PMID:27134568

The use of purposeful sampling in a qualitative evidence synthesis: A worked example on sexual adjustment to a cancer trajectory.

PubMed

Benoot, Charlotte; Hannes, Karin; Bilsen, Johan

2016-02-18

An increasing number of qualitative evidence syntheses papers are found in health care literature. Many of these syntheses use a strictly exhaustive search strategy to collect articles, mirroring the standard template developed by major review organizations such as the Cochrane and Campbell Collaboration. The hegemonic idea behind it is that non-comprehensive samples in systematic reviews may introduce selection bias. However, exhaustive sampling in a qualitative evidence synthesis has been questioned, and a more purposeful way of sampling papers has been proposed as an alternative, although there is a lack of transparency on how these purposeful sampling strategies might be applied to a qualitative evidence synthesis. We discuss in our paper why and how we used purposeful sampling in a qualitative evidence synthesis about 'sexual adjustment to a cancer trajectory', by giving a worked example. We have chosen a mixed purposeful sampling, combining three different strategies that we considered the most consistent with our research purpose: intensity sampling, maximum variation sampling and confirming/disconfirming case sampling. The concept of purposeful sampling on the meta-level could not readily been borrowed from the logic applied in basic research projects. It also demands a considerable amount of flexibility, and is labour-intensive, which goes against the argument of many authors that using purposeful sampling provides a pragmatic solution or a short cut for researchers, compared with exhaustive sampling. Opportunities of purposeful sampling were the possible inclusion of new perspectives to the line-of-argument and the enhancement of the theoretical diversity of the papers being included, which could make the results more conceptually aligned with the synthesis purpose. This paper helps researchers to make decisions related to purposeful sampling in a more systematic and transparent way. Future research could confirm or disconfirm the hypothesis of conceptual enhancement by comparing the findings of a purposefully sampled qualitative evidence synthesis with those drawing on an exhaustive sample of the literature.

An evidence-based HIV prevention intervention was adapted for Botswana youth with qualitative interviews, input from an adolescent panel, and social validation. Qualitative interviews were conducted with 40 boys and girls ages 13-19. An adolescent panel then drafted scenarios reflecting social situations described in the interviews that posed risk for HIV. A social validation sample (N = 65) then indicated the prevalence and difficulty of each situation. Youth described informational needs, pressures to use alcohol and drugs, peer pressure for unprotected sex, and intergenerational sex initiations as risk-priming situations. From 17% to 57% of the social validation sample had personally experienced the situations drafted by the adolescent panel. There were no differences in the ratings of boys versus girls, but youth over age 16 more often reported that they had experienced these risky situations. The results were embedded into the intervention. Major changes to the intervention resulted from this three-phase process.

2014-05-01

Social responsibility is intertwined with nursing; however, perceptions of Iranian nurses about social responsibility has not been explored yet. This study, as part of a larger qualitative grounded theory approach study, aims to explore Iranian nurses' perception of social responsibility. The study participants included 10 nurses with different job levels. The study data were generated through semi-structured interviews. The participants were selected through purposeful sampling approach, which was then followed by theoretical sampling until reaching the point of data saturation. All the interviews were recorded, transcribed, and analyzed through constant comparative analysis. Positive human characteristics, professional competencies, professional values, solution-focused nursing care, and deployment of professional performance are five categories obtained from the study. The participants believed socially responsible nurses to have positive personality characteristics as well as the necessary skills to do their duties accurately. Such nurses also respect the values, observe the professional principles, and take major steps toward promotion and deployment of the nursing profession in the society.

Postpartum depression and culture: Pesado Corazon.

Callister, Lynn Clark; Beckstrand, Renea L; Corbett, Cheryl

2010-01-01

The purpose of this article is to describe what the literature has shown about postpartum depression (PPD) in culturally diverse women. The majority of qualitative studies done with women identified as having PPD have been conducted with Western women, with the second largest group focusing on Chinese women. This article reviews the qualitative studies in the literature and discusses how the management of PPD in technocentric and ethnokinship cultures differs. Social support has been shown to be significantly related to fewer symptoms of PPD, and culturally prescribed practices may or may not be cultural mediators in decreasing the incidence of PPD. Nurses should be sensitive to the varied ways in which culturally diverse women perceive, explain, and report symptoms of PPD. Exemplary interventions for culturally diverse women suffering from PPD are examined in this article as well, although it is clear that additional research is needed to develop models for culturally competent interventions for PPD in culturally diverse women and to document the outcomes of such interventions.

This qualitative study at Mashhad University of Medical Sciences aimed to elucidate the views of medical faculty staff on the components of cross-cultural competence and compare these with similar studies published in English. Using a combination of archival studies, semi-structured interviews and focus group discussions among faculty members 3 major domains (knowledge, attitude and behaviour) and 21 components were identified to describe the cross-cultural competence of faculty members in medical schools. Participants expressed the importance of knowledge as a precursor to changing attitudes and the 6 knowledge components related to knowledge and awareness of values, beliefs and norms of different ethnic, racial and cultural groups. Experts mostly emphasized the importance of interaction between faculty members and clients (students and patients).

To respond efficiently to the increasing and new needs of people in health issues, it is necessary for nurses to develop their knowledge from hospital to society and to be equipped to play entrepreneur role in different levels of care. The present study was conducted to describe Iranian entrepreneur nurses' perceived barriers to entrepreneurship, in order to identify the existing barriers. This is a qualitative study in which Graneheim and Lundman's content analysis method was employed. Thirteen entrepreneur nurses were chosen purposively, and data were gathered by unstructured interviews. As a result of the data analysis, five major themes were extracted: Traditional nursing structure, legal limitations, traditional attitudes of governmental managers, unprofessional behaviors of colleagues, and immoral business. The findings of the present study show that Iranian nurses are confronted with various problems and barriers to enter entrepreneur nursing and keep going in this area. By focusing on such barriers and applying appropriate changes, policymakers and planners in health can facilitate nurses entering into this activity.

An emerging challenge in plant biology is to develop qualitative and quantitative measures to describe the appearance of plants through the integration of mathematics and biology. A major hurdle in developing these metrics is finding common terminology across fields. In this review, we define approaches for analyzing plant geometry, topology, and shape, and provide examples for how these terms have been and can be applied to plants. In leaf morphological quantifications both geometry and shape have been used to gain insight into leaf function and evolution. For the analysis of cell growth and expansion, we highlight the utility of geometric descriptors for understanding sepal and hypocotyl development. For branched structures, we describe how topology has been applied to quantify root system architecture to lend insight into root function. Lastly, we discuss the importance of using morphological descriptors in ecology to assess how communities interact, function, and respond within different environments. This review aims to provide a basic description of the mathematical principles underlying morphological quantifications. PMID:28217137

An internationalized curriculum in nursing education was created in response to the rise of globalization and the need to provide nursing care to people of diverse cultures. Through technology, internationalization at home can facilitate intercultural experiences for more nursing students. The aim of this study is to explore and describe how a virtual course in intercultural communication between students of two universities, through internationalization at home, can support the development of cultural competence. Qualitative research Junior year nursing students Qualitative content analysis of transcribed written and oral presentations during a course on intercultural communication. Four major themes, which are not mutually exclusive, were identified. Through this intercultural experience, without leaving home, students uncovered their cultural selves and others based on their own reflective understanding and collaborative discourse with each other and the use of social media for communication. Through experiential intercultural encounters beyond textbook and online materials, they learned to appreciate each other as people with cultural differences yet with much in common, and to recognize their assumptions and the value of subtleties and nuances. They were able to explore solutions within an unfamiliar context through their own efforts and with the support of peers and teachers. This led to a deeper understanding of cultural sensitivity and competence. Copyright © 2015 Elsevier Ltd. All rights reserved.

Hypnosis is recognised in medicine as an effective complementary therapy. However, few qualitative data are available concerning the benefits it may bring. This qualitative exploratory study aimed to examine the contribution of hypnosis to the care of advanced cancer patients. Results demonstrate that hypnosis is an effective and efficient means of developing the resources of people suffering from serious illness. After an average of four hypnotherapy sessions, patients said they were able to locate previously unexploited resources within themselves and were able to become autonomous in the use of self-hypnosis. The major benefit reported concerned a reduction in anxiety. For patients experiencing anxiety about death, hypnosis allowed them, within a therapeutic environment perceived as safe, to explore different facets of their fears and to develop adaptive strategies. Aside from slight fatigue experienced during the sessions, no adverse side-effects were reported. In conclusion, this study exploring the effects of hypnosis allowed us to identify important benefits for patients suffering from advanced cancer. Consequently, replication on a larger scale is recommended in order to ascertain the extent to which it is possible to generalise from these results and in order better to define the characteristics of patients most likely to benefit from this therapy.

Continuing professional development and education is vital to the provision of better health services and outcomes. The aim of this study is to contribute to the evidence base by performing a systematic review of qualitative data from studies reporting health professionals' experience of e-learning. No such previous review has been published. A systematic review of qualitative data reporting UK health professionals' experiences of the ways in which on-line learning is delivered by higher education and other relevant institutions. Evidence synthesis was performed with the use of thematic analysis grounded in the data. Literature searches identified 19 relevant studies. The subjects of the studies were nurses, midwives, and allied professions (8 studies), general practitioners and hospital doctors (6 studies), and a range of different health practitioners (5 studies). The majority of courses were stand-alone continuing professional development modules. Five key themes emerged from the data: peer communication, flexibility, support, knowledge validation, and course presentation and design. The effectiveness of on-line learning is mediated by the learning experience. If they are to enhance health professionals' experience of e-learning, courses need to address presentation and course design; they must be flexible, offer mechanisms for both support and rapid assessment, and develop effective and efficient means of communication, especially among the students themselves.

Blended cognitive behavioural therapy (bCBT), which combines face-to-face (FtF), and internet-based cognitive behavioural therapy (iCBT), may be a particularly promising approach, but little is known about the effectiveness and patients' subjective evaluations of the bCBT format. The aim of this qualitative study is to explore perceived advantages and disadvantages of bCBT from the patients' perspective in specialized mental health care. Semi-structured interviews were conducted with 15 patients suffering from major depression who underwent treatment in a bCBT format. The interview data were processed by means of a qualitative content analysis. The content analysis generated 18 advantages and 15 disadvantages which were grouped into 6 main topics. In general, bCBT was perceived as purposive and effective for treating depression. The patients perceived the combined treatment as complementary and emphasized the advantage of the constant availability of the online programme. Furthermore, a segment analysis revealed that patients reported different advantages and disadvantages of bCBT as a function of the severity of their depressive episode. The findings of the present study reveal advantages and disadvantages of bCBT, which should be taken into account in the further implementation of this new treatment format.

Yogurts, fermented milk beverages, and fermented milks have great similarity and are widely accepted by Brazilian population, but the factors that influence their choice and consumption are unknown. In this sense, the present study aimed to identify the main aspects involved in consumers' perception of 3 different products, comparing the findings by using the 2 fast qualitative methods, word association and projective mapping, and a standard method, focus group. The tasks were performed by different participants through graphic stimuli (word association and projective mapping) and focus interviews (focus group). Results showed that all the 3 methodologies identified numerous intrinsic and extrinsic factors that influence the consumer choices regarding fermented dairy products. Major dimensions were closely related to the sensory aspects, emotional factors, perception of benefits, and composition, among others. It is noteworthy that the stimuli related to fermented milk beverages evoked rejecting responses, possibly due to the dissociation between information and consumers' expectation. Although minor differences were observed between the number and type of dimensions that were obtained, similar conclusions can be drawn from all 3 sensory methods, which shows the relevance of qualitative and projective methods for investigation of consumers' perception. These findings can help dairy companies to provide subsidies and guidelines for the reformulation of their products, marketing strategies, and improvement in the communication between producers and consumers from different fermented dairy products.

Circular motion and Polish Doughnuts in NUT spacetime

NASA Astrophysics Data System (ADS)

Jefremov, Paul I.

The astrophysical relevance of the NUT spacetime(s) is a matter of debate due to pathological properties exhibited by this solution. However, if it is realised in nature, then we should look for the characteristic imprints of it on possible observations. One of the major sources of data on black hole astrophysics is the accretion process. Using a simple but fully analytical ``Polish Doughnuts'' model of accretion disk one gets both qualitative and quantitative differences from the Kerr spacetime produced by the presence of the gravitomagnetic charge. The present paper is based on our work Jefremov & Perlick (2016).

Research developing targeted treatment focused on coping with children's long-term pain after surgery is needed because of the high prevalence of chronic pain after surgery. This qualitative study aimed to: 1) understand the child's and family's experiences of pain over the course of their surgical experience, and 2) gather stakeholder input regarding potential barriers and facilitators of perioperative intervention delivery. Fifteen children ages 10 to 18 years who underwent recent major surgery, their primary caregivers, and 17 perioperative health care providers were interviewed. Interviews were coded using semantic thematic analysis. The perioperative period presented emotional challenges for families. Families felt unprepared for surgery and pain. Recovery and regaining physical functioning at home was challenging. Families struggled to return to valued activities. Families reported interest in a perioperative psychosocial intervention. Providers endorsed that families would benefit from enhanced coping skills. They emphasized that families would benefit from more detailed preparatory information. Providers suggested that flexible intervention delivery at home would be ideal. Research developing interventions addressing pain and anxiety in children undergoing major surgery is critically needed. The findings of the present study can inform intervention development with the aim of improving short- as well as long-term recovery in children undergoing major surgery. This qualitative study examined children and their parents' experience of long-term pain and recovery after major surgery, identifying barriers and facilitators of perioperative intervention delivery. Families experienced surgery as stressful, and felt underprepared for pain and recovery. Families and health care providers expressed interest in a preoperative intervention teaching coping skills.

A Computational Approach to Qualitative Analysis in Large Textual Datasets

PubMed Central

Evans, Michael S.

2014-01-01

In this paper I introduce computational techniques to extend qualitative analysis into the study of large textual datasets. I demonstrate these techniques by using probabilistic topic modeling to analyze a broad sample of 14,952 documents published in major American newspapers from 1980 through 2012. I show how computational data mining techniques can identify and evaluate the significance of qualitatively distinct subjects of discussion across a wide range of public discourse. I also show how examining large textual datasets with computational methods can overcome methodological limitations of conventional qualitative methods, such as how to measure the impact of particular cases on broader discourse, how to validate substantive inferences from small samples of textual data, and how to determine if identified cases are part of a consistent temporal pattern.

2015-01-01

Currently, we lack a clear picture of the evolution of major depressive disorder (MDD) in adolescents. The period of disturbance preceding MDD can be conceptualised as the prodrome. The aim of the study was to explore the prodrome of first-episode MDD retrospectively in a group of help-seeking adolescents using qualitative methodologies. Consecutively referred adolescents (15-18 years of age) with first-episode MDD were recruited for this study from Orygen Youth Health, Melbourne, Vic., Australia. After using quantitative methodologies to confirm the index episode of MDD and measure the extent of recovery, the prodrome was investigated in depth using qualitative techniques. Twenty-nine adolescents (20 females and 9 males) and 7 informants (6 mothers and 1 grandmother) participated. All 29 participants had a prodrome of varying lengths (between 6 days and 4 years). The most noticeable symptoms initially were perplexity and confusion and, thereafter, sadness and irritability. A common pattern was a reduction in their ability to fulfil their role accompanied by guilt, self-blame and reduced self-esteem. Around half of the participants had increased thoughts of suicide and increased anxiety. There were gender differences in the patterns of symptoms noticed, with males more commonly noticing a change in how they related to the world and females more commonly noticing a change in the way that they related to others. All informants noticed a prodrome of varying lengths; in 2 cases longer, in 2 cases shorter and in 3 cases around the same time period as that noticed by the participant. The changes most commonly noticed by informants were sadness, upset, irritability and reduced self-esteem. The symptoms were fewer in number and sometimes varied from those noticed by the adolescents themselves. Whilst we recognise that this study is vulnerable to autobiographical bias, we took all reasonable measures to minimise this. Symptoms not included in the diagnostic criteria for depression were the earliest changes noticed by the adolescents themselves and are, therefore, potentially important in informing prevention strategies, as is the finding that there are gender differences in the patterns of changes noticed. In addition, parents may provide an additional avenue to help seeking.

To compare the contribution of "trial-sibling" and "unrelated" qualitative studies in complex intervention reviews. Researchers are using qualitative "trial-sibling" studies undertaken alongside trials to provide explanations to understand complex interventions. In the absence of qualitative "trial-sibling" studies, it is not known if qualitative studies "unrelated" to trials are helpful. Trials, "trial-sibling," and "unrelated" qualitative studies looking at three health system interventions were identified. We looked for similarities and differences between the two types of qualitative studies, such as participants, intervention delivery, context, study quality and reporting, and contribution to understanding trial results. Reporting was generally poor in both qualitative study types. We detected no substantial differences in participant characteristics. Interventions in qualitative "trial-sibling" studies were delivered using standardized protocols, whereas interventions in "unrelated" qualitative studies were delivered in routine care. Qualitative "trial-sibling" studies alone provided insufficient data to develop meaningful transferrable explanations beyond the trial context, and their limited focus on immediate implementation did not address all phenomena of interest. Together, "trial-sibling" and "unrelated" qualitative studies provided larger, richer data sets across contexts to better understand the phenomena of interest. Findings support inclusion of "trial-sibling" and "unrelated" qualitative studies to explore complexity in complex intervention reviews. Copyright © 2016 Elsevier Inc. All rights reserved.

Teaching science in a technology rich environment: Probeware's effect on student attitude and achievement

NASA Astrophysics Data System (ADS)

Zelmanowicz, Marc

Purpose The use of technology in the science classroom has been a major part of the initiative toward increasing student attitude and achievement in Science, Technology, Education and Math [STEM] education in the United States. The purpose of this study was to determine the extent to which the use of probeware in a high school science living environment classroom impacts student attitude towards science and/or student achievement on standards-based assessments. This study sought to answer the following quantitative questions with a qualitative component: To what extent does the use of probeware in a high school level living environment course influence student attitudes toward science compared to students who are not using probeware? What is the impact, if any, on student achievement in a living environment course, as measured by New York State Living Environment Regents [NYSLER] exam grades, between students who use probeware and students who do not? Is there a significant difference between the two groups with regard to achieving mastery on the NYSLER exam? Sample The participants in the study were Living Environment students of a suburban high school outside of New York City. Methods The quasiexperimental study examined the effects of the replacement of traditional scientific equipment with probeware on student attitude and achievement in a living environment classroom. Student attitude was measured by the modified Attitude Toward Science Inventory [mATSI] and student achievement was measured by the New York State Living Environment Regents [NSLER] Exam. Descriptive statistics, ANCOVA and hierarchical regression analysis were conducted to answer the research questions in this study. A qualitative component was included to enhance the understanding of the quantitative analysis. Major Findings Through this study, results demonstrated a statistically significant impact of probeware on student attitude, but did not show a statistically significant impact of probeware on student achievement or achievement of mastery; The qualitative component confirmed that probeware positively impact student attitude and achievement. With regards to achievement, the qualitative interviews contradicted the quantitative analysis. Significance Results from this study add to the body of research that probeware can impact student attitude towards science education.

Qualitative and quantitative prediction of volatile compounds from initial amino acid profiles in Korean rice wine (makgeolli) model.

In Korean rice wine (makgeolli) model, we tried to develop a prediction model capable of eliciting a quantitative relationship between initial amino acids in makgeolli mash and major aromatic compounds, such as fusel alcohols, their acetate esters, and ethyl esters of fatty acids, in makgeolli brewed. Mass-spectrometry-based electronic nose (MS-EN) was used to qualitatively discriminate between makgeollis made from makgeolli mashes with different amino acid compositions. Following this measurement, headspace solid-phase microextraction coupled to gas chromatography-mass spectrometry (GC-MS) combined with partial least-squares regression (PLSR) method was employed to quantitatively correlate amino acid composition of makgeolli mash with major aromatic compounds evolved during makgeolli fermentation. In qualitative prediction with MS-EN analysis, the makgeollis were well discriminated according to the volatile compounds derived from amino acids of makgeolli mash. Twenty-seven ion fragments with mass-to-charge ratio (m/z) of 55 to 98 amu were responsible for the discrimination. In GC-MS combined with PLSR method, a quantitative approach between the initial amino acids of makgeolli mash and the fusel compounds of makgeolli demonstrated that coefficient of determination (R(2)) of most of the fusel compounds ranged from 0.77 to 0.94 in good correlation, except for 2-phenylethanol (R(2) = 0.21), whereas R(2) for ethyl esters of MCFAs including ethyl caproate, ethyl caprylate, and ethyl caprate was 0.17 to 0.40 in poor correlation. The amino acids have been known to affect the aroma in alcoholic beverages. In this study, we demonstrated that an electronic nose qualitatively differentiated Korean rice wines (makgeollis) by their volatile compounds evolved from amino acids with rapidity and reproducibility and successively, a quantitative correlation with acceptable R2 between amino acids and fusel compounds could be established via HS-SPME GC-MS combined with partial least-squares regression. Our approach for predicting the quantities of volatile compounds in the finished product from initial condition of fermentation will give an insight to food researchers to modify and optimize the qualities of the corresponding products. © 2014 Institute of Food Technologists®

Qualitative data analysis: conceptual and practical considerations.

PubMed

Liamputtong, Pranee

2009-08-01

Qualitative inquiry requires that collected data is organised in a meaningful way, and this is referred to as data analysis. Through analytic processes, researchers turn what can be voluminous data into understandable and insightful analysis. This paper sets out the different approaches that qualitative researchers can use to make sense of their data including thematic analysis, narrative analysis, discourse analysis and semiotic analysis and discusses the ways that qualitative researchers can analyse their data. I first discuss salient issues in performing qualitative data analysis, and then proceed to provide some suggestions on different methods of data analysis in qualitative research. Finally, I provide some discussion on the use of computer-assisted data analysis.

Sampling in Qualitative Research

2011-01-01

In gerontology the most recognized and elaborate discourse about sampling is generally thought to be in quantitative research associated with survey research and medical research. But sampling has long been a central concern in the social and humanistic inquiry, albeit in a different guise suited to the different goals. There is a need for more explicit discussion of qualitative sampling issues. This article will outline the guiding principles and rationales, features, and practices of sampling in qualitative research. It then describes common questions about sampling in qualitative research. In conclusion it proposes the concept of qualitative clarity as a set of principles (analogous to statistical power) to guide assessments of qualitative sampling in a particular study or proposal.

Western music has two classifications that are highly familiar to all Western listeners: the dichotomy between the major and minor modalities and consonance vs. dissonance. We aimed at determining whether these classifications already take place at the level of the elicitation of the change-related mismatch negativity (MMN) component of the event-related potential (ERP). To this end, we constructed an oddball-paradigm with root minor, dissonant and inverted major chords in a context of root major chords. These stimuli were composed so that the standard and deviant chords did not include a physically deviant frequency which could cause the MMN. The standard chords were transposed into 12 different keys (=pitch levels) and delivered to the participants while they were watching a silent movie (ignore condition) or detecting softer target sounds (detection condition). In the ignore condition, the MMN was significant for all but inverted major chords. In the detection condition, the MMN was significant for dissonant chords and soft target chords. Our results indicate that the processes underlying MMN are able to make discriminations which are qualitative by nature. Whether the classifications between major and minor modalities and consonance vs. dissonance are innate or based on implicit learning remains a question for the future.

2012-03-01

This paper will start from focusing on the limitations of quantitative approach in psychology from three viewpoints. First--data collection, especially experiments and questionnaires as two major methods of quantitative approach. The second limitation is data aggregation, followed by the third--statistical significance testing. After that, recent spread of qualitative approach as another option for one of psychological methods will be introduced and a controversy surrounding epistemology of qualitative approach will be also introduced. Finally, it will be discussed that accumulation of faithful descriptions on reality, especially from qualitative approach, would be needed for producing creative research.

Perspectives of speech-language pathologists on the use of telepractice in schools: the qualitative view.

PubMed

Tucker, Janice K

2012-01-01

Telepractice in speech-language pathology shows the potential to mitigate the current shortage of speech-language pathologists (SLPs) available to serve a growing number of persons with communication disorders. Since a majority of American Speech-Language-Hearing Association (ASHA) certified SLPs work in schools and the population of communicatively impaired clients in schools continues to grow, research into the use of telepractice in the educational setting is warranted. This article reports upon the perspectives of SLPs regarding the use of telepractice in school settings. In-depth qualitative interviews were conducted with five SLPs experienced in the delivery of telepractice. Four major themes emerged: barriers, benefits, reasons for acceptance and use of telepractice, and suggestions to resolve telepractice professional issues.

How will we know "good" qualitative research when we see it? Beginning the dialogue in health services research.

PubMed Central

Devers, K J

1999-01-01

OBJECTIVE: To lay the foundation for an explicit review and dialogue concerning the criteria that should be used to evaluate qualitative health services research. Clear criteria are critical for the discipline because they provide a benchmark against which research can be assessed. DATA SOURCES: Existing literature in the social sciences and health services research, particularly in primary care and medicine. PRINCIPAL FINDING: Traditional criteria for evaluating qualitative research are rooted in the philosophical perspective (positivism) most closely associated with quantitative research and methods. As a result, qualitative research and methods may not be used as frequently as they can be and research results generated from qualitative studies may not be disseminated as widely as possible. However, alternative criteria for evaluating qualitative research have been proposed that reflect a different philosophical perspective (post-positivism). Moreover, these criteria are tailored to the unique purposes for which qualitative research is used and the research designs traditionally employed. While criteria based on these two different philosophical perspectives have much in common, some important differences exist. CONCLUSION: The field of health services research must engage in a collective, "qualitative" process to determine which criteria to adopt (positivist or post-positivist), or whether some combination of the two is most appropriate. Greater clarity about the criteria used to evaluate qualitative research will strengthen the discipline by fostering a more appropriate and improved use of qualitative methods, a greater willingness to fund and publish "good" qualitative research, and the development of more informed consumers of qualitative research results.

Barriers and facilitators of adherence to antidepressants among outpatients with major depressive disorder: A qualitative study

PubMed Central

Jacob, Sabrina Anne; Tangiisuran, Balamurugan

2017-01-01

Background One of the major challenges in treating major depressive disorder (MDD) is patients’ non-adherence to medication. This study aimed to explore the barriers and facilitators of patients’ adherence to antidepressants among outpatients with MDD. Methods Semi-structured and individual in-depth interviews were conducted among patients with MDD who were taking antidepressants, in the psychiatric clinic of a government-run hospital in Malaysia. Participants were purposively sampled from different genders and ethnicities. Interviews were conducted using a validated topic guide, and responses were audio-recorded, transcribed verbatim, checked, and analyzed using the grounded theory approach. Results A total of 30 patients were interviewed. Forty different themes and sub-themes were identified which were conceptually divided into two distinct categories related to barriers and facilitators to adherence. The barriers were: patient-specific, medication-specific, healthcare provision and system, social-cultural, and logistics. The facilitators were: having insight, perceived health benefits, regular activities, patient-provider relationship, reminders, and social support networks. Conclusions Patient-specific barriers and medication side effects were the major challenges for adhering to treatment. Perceived health benefits and having insight on the need for treatment were the most frequently cited facilitators. Targeted interventions should be developed to address the key barriers, and promote measures to facilitate adherence in this group of patients. PMID:28614368

Objective: Food choice is a process through which people think, feel, and eat food. It does not only influence individuals' health and well-being, families and communities, but also it has an effect on regional, national, and global levels. This qualitative study was conducted to explore perceptions and lived experiences of Tehran adult residents on psychological, social and cultural determinants of food choice. Method: In this qualitative design, we recruited 33 adults aged 30 to 64 years from various districts of Tehran, capital of Iran, and we explored how people make decisions about food choice in practice and shape their perception, attitude, and eating practices. An individual in-depth semi-structured interview guide included major questions with follow-up probes was used to explore participants’ current and past eating habits from childhood to adulthood, dietary change at different life courses, and effective psychological state on food selection in different seasons. Results: This study revealed that food choice in the studied adults (30-64 years old) was widely influenced by psychological, social, and cultural determinants, which can be categorized into 5 main themes: cultural context and patterns; social Structure and norms; information resources and media; household and family structure; and nutrition transition. Conclusion: The findings clarified the importance of social and cultural contexts, which influence the food choice of adults in a metropolis like Tehran. Many of these concepts are contextualized from childhood. These findings could serve as guideline to design socio-culturally appropriate strategies and improve dietary behaviors of Iranians.

2017-02-01

We aimed to describe how qualitative methods are used in global research on diabetes and identify opportunities whereby qualitative methods could further benefit our understanding of the human experience of diabetes and interventions to address it. We conducted a systematic review of National Library of Medicine, EMBASE, and Web of Science electronic databases to identify original research articles that used qualitative methods to study diabetes between 1980 and 2011. We identified 554 eligible articles and categorised these by geographic region, year of publication, study population, study design, research question, qualitative data collection methods, and journal type. Results show low use of qualitative methods in diabetes research over the past 30 years. The majority of articles (75%) reported using substantive qualitative research, while mixed-methods research has remained underutilised. Eighty-five per cent of articles reported studies conducted in North America or Europe, with few studies in developing countries. Most articles reported recruiting clinic-based populations (58%). Over half (54%) of research questions focused on patient experience and 24% on diabetes management. Qualitative methods can provide important insights about socio-cultural aspects of disease to improve disease management. However, they remain underutilised for understanding the diabetes experience, especially in Africa and Asia and amongst non-clinic populations.

Reporting Qualitative Research: Standards, Challenges, and Implications for Health Design.

PubMed

Peditto, Kathryn

2018-04-01

This Methods column describes the existing reporting standards for qualitative research, their application to health design research, and the challenges to implementation. Intended for both researchers and practitioners, this article provides multiple perspectives on both reporting and evaluating high-quality qualitative research. Two popular reporting standards exist for reporting qualitative research-the Consolidated Criteria for Reporting Qualitative Research (COREQ) and the Standards for Reporting Qualitative Research (SRQR). Though compiled using similar procedures, they differ in their criteria and the methods to which they apply. Creating and applying reporting criteria is inherently difficult due to the undefined and fluctuating nature of qualitative research when compared to quantitative studies. Qualitative research is expansive and occasionally controversial, spanning many different methods of inquiry and epistemological approaches. A "one-size-fits-all" standard for reporting qualitative research can be restrictive, but COREQ and SRQR both serve as valuable tools for developing responsible qualitative research proposals, effectively communicating research decisions, and evaluating submissions. Ultimately, tailoring a set of standards specific to health design research and its frequently used methods would ensure quality research and aid reviewers in their evaluations.

Integrating qualitative research into evidence based practice.

Greenhalgh, Trisha

2002-09-01

This article attempts to provide an overview of qualitative tools and methods using mainly examples from diabetes research. The other articles in this issue of the Endocrinology and Metabolism Clinics of North America have demonstrated the enormous contribution made in the past 15 years or so by rigorous quantitative studies of prevalence, diagnosis, prognosis, and therapy to clinical decision-making in endocrinology. In the early 21st century, the state of qualitative research into such topics as the illness experience of diabetes; the barriers to effective self care and positive health choices; the design of complex educational interventions; the design of appropriate, acceptable and responsive health services; and the decision-making behavior of health professionals, is such that there remain many more questions than answers. But qualitative research is increasingly recognized as an important, legitimate and expanding dimension of evidence-based health care (18;19). It is highly likely that the major landmark studies in diabetes care over the next decade will build on an exploratory qualitative study or incorporate an explanatory or evaluative dimension based on qualitative methods.

Locating qualitative studies in dementia on MEDLINE, EMBASE, CINAHL, and PsycINFO: A comparison of search strategies.

Qualitative research in dementia improves understanding of the experience of people affected by dementia. Searching databases for qualitative studies is problematic. Qualitative-specific search strategies might help with locating studies. To examine the effectiveness (sensitivity and precision) of 5 qualitative strategies on locating qualitative research studies in dementia in 4 major databases (MEDLINE, EMBASE, PsycINFO, and CINAHL). Qualitative dementia studies were checked for inclusion on MEDLINE, EMBASE, PsycINFO, and CINAHL. Five qualitative search strategies (subject headings, simple free-text terms, complex free-text terms, and 2 broad-based strategies) were tested for study retrieval. Specificity, precision and number needed to read were calculated. Two hundred fourteen qualitative studies in dementia were included. PsycINFO and CINAHL held the most qualitative studies out the 4 databases studied (N = 171 and 166, respectively) and both held unique records (N = 14 and 7, respectively). The controlled vocabulary strategy in CINAHL returned 96% (N = 192) of studies held; by contrast, controlled vocabulary in PsycINFO returned 7% (N = 13) of studies held. The broad-based strategies returned more studies (93-99%) than the other free-text strategies (22-82%). Precision ranged from 0.061 to 0.004 resulting in a number needed to read to obtain 1 relevant study ranging from 16 (simple free-text search in CINAHL) to 239 (broad-based search in EMBASE). Qualitative search strategies using 3 broad terms were more sensitive than long complex searches. The controlled vocabulary for qualitative research in CINAHL was particularly effective. Furthermore, results indicate that MEDLINE and EMBASE offer little benefit for locating qualitative dementia research if CINAHL and PSYCINFO are also searched.

The perpetual search for parsimony: enhancing the epistemological and practical utility of qualitative research findings.

PubMed

Cutcliffe, John R; Harder, Henry G

2009-10-01

While it appears that the term parsimony has been used in the context of qualitative research and qualitative research methodology, there is a distinct absence of writing that actually explores, seeks to define, understand, critique, apply and/or evaluate the concept in qualitative research literature. This paper explores a number of issues pertaining to parsimony in qualitative research. It is the hope of the authors that this paper might raise awareness of the hitherto unexplored issues, stimulate some further interest in these and prompt other qualitative researchers to contribute to the ensuing debate. While there are currently no definitive criteria for determining the parsimony of qualitative research findings, it would be epistemologically inappropriate and philosophically incongruent to import and translate quantitative notions of parsimony. However, the ideas, principles and epistemological functions that parsimony serves can and should be applied to the qualitative paradigm. The authors suggest that more than one type of qualitative parsimony is required. The authors advance the argument that there is a relationship between the degree of parsimony and the elegance, ease of accessibility and straightforwardness (some might say - beauty) of the writing/findings; the level of expertise of the researcher; and the quality of the data collection interview. The authors also assert that there are a number of practices which, when adhered to, can enhance the parsimony of the findings and that here are a number of major implications arising from qualitative findings that lack parsimony.

‘Even though a man takes the major role, he has no right to abuse’: future male leaders’ views on gender-based violence in Sri Lanka

ABSTRACT Background: Distinct gender roles influence gender inequality and build the foundation for gender-based violence. Violence against women is a major public health problem in all societies, and a violation of human rights. Prevalence surveys on gender-based violence have been published from Sri Lanka, but qualitative studies on men’s perceptions are lacking. Objectives: The aim of this study was to explore young educated Sri Lankan men’s perceptions of violence against women. Methods: Seven focus-group discussions were held. Men at the end of their university studies were purposefully selected. A topic guide was used, covering various scenarios of violence against women. Qualitative content analysis was carried out. Results: Four categories were developed through the analytic process: fixed gender roles – patriarchal values are accepted in society, female mobility control, and slowly changing attitudes; violence not accepted but still exists – sexual harassment exists everywhere, different laws for different people, female tolerance of violence, and men’s right to punish; multiple factors cause violence – alcohol, violent behavior is inherited, violence culturally accepted, low education, and lack of communication; and prevention of violence against women – both parents must engage and socialize girls and boys equally, life skills education, premarital counselling, working places value clarification, and more women in politics and boards are suggested. Conclusions: Medical and management students, possible future male leaders of the country, have suggestions of prevention strategies in life skills to reduce gender-based violence and to increase knowledge of health consequences with the aim of changing attitudes.

Background Despite the availability of evidence-based guidance, many patients with type 2 diabetes do not achieve treatment goals. Aim To guide quality improvement strategies for type 2 diabetes by synthesising qualitative evidence on primary care physicians’ and nurses’ perceived influences on care. Design and setting Systematic review of qualitative studies with findings organised using the Theoretical Domains Framework. Method Databases searched were MEDLINE, Embase, CINAHL, PsycInfo, and ASSIA from 1980 until March 2014. Studies included were English-language qualitative studies in primary care of physicians’ or nurses’ perceived influences on treatment goals for type 2 diabetes. Results A total of 32 studies were included: 17 address general diabetes care, 11 glycaemic control, three blood pressure, and one cholesterol control. Clinicians struggle to meet evolving treatment targets within limited time and resources, and are frustrated with resulting compromises. They lack confidence in knowledge of guidelines and skills, notably initiating insulin and facilitating patient behaviour change. Changing professional boundaries have resulted in uncertainty about where clinical responsibility resides. Accounts are often couched in emotional terms, especially frustrations over patient compliance and anxieties about treatment intensification. Conclusion Although resources are important, many barriers to improving care are amenable to behaviour change strategies. Improvement strategies need to account for differences between clinical targets and consider tailored rather than ‘one size fits all’ approaches. Training targeting knowledge is necessary but insufficient to bring about major change; approaches to improve diabetes care need to delineate roles and responsibilities, and address clinicians’ skills and emotions around treatment intensification and facilitation of patient behaviour change.

Posttraumatic stress disorder (PTSD) is the most prevalent compensable mental disorder within the U.S. Department of Veterans Affairs disability system and the number of veterans with PTSD service-connected disability has increased steadily over the past decade. An understanding of the reasons veterans apply for PTSD disability status may inform interpretation of this increase and policies and interventions to assist veterans with military-related PTSD. The authors conducted an exploratory qualitative study to describe the reasons veterans seek PTSD disability benefits and explored differences between those who served in different military service eras. They gathered data through in-depth interviews with 44 purposefully selected U.S. veterans, and conducted content analysis of transcribed interviews using inductive and deductive analysis with constant comparison. Participants described 5 interrelated categories of reasons for seeking PTSD disability benefits, including 3 internal factors (tangible need, need for problem identification or clarification, beliefs that justify/legitimize PTSD disability status) and 2 external factors (encouragement from trusted others and professional assistance). There were no major differences by service era. Findings may help policy makers, providers, and researchers understand what veterans hope to achieve through PTSD disability and the instrumental role of social networks and government systems in promoting the pursuit of PTSD disability status.

Arthrospira platensis , better known as Spirulina, is one of the most important microalgae species. This cyanobacterium possesses a rich metabolite pattern, including high amounts of natural pigments. In this study, we applied a combined strategy based on Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (FT-ICR-MS) and Ultra High-Performance Liquid Chromatography (UHPLC) for the qualitative/quantitative characterization of Spirulina pigments in three different commercial dietary supplements. FT-ICR was employed to elucidate the qualitative profile of Spirulina pigments, in both direct infusion mode (DIMS) and coupled to UHPLC. DIMS showed to be a very fast (4 min) and accurate (mass accuracy ≤ 0.01 ppm) tool. 51 pigments were tentatively identified. The profile revealed different classes, such as carotenes, xanthophylls and chlorophylls. Moreover, the antioxidant evaluation of the major compounds was assessed by pre-column reaction with the DPPH radical followed by fast UHPLC-PDA separation, highlighting the contribution of single analytes to the antioxidant potential of the entire pigment fraction. β-carotene, diadinoxanthin and diatoxanthin showed the highest scavenging activity. The method took 40 min per sample, comprising reaction. This strategy could represent a valid tool for the fast and comprehensive characterization of Spirulina pigments in dietary supplements, as well as in other microalgae-based products.

The composition of the essential oil from ripe and unripe berries and leaves of Juniperus oxycedrus L. ssp. oxycedrus, Juniperus phoenicea ssp. turbinata and Juniperus communis ssp. communis was analyzed by GC-MS, and microbiological assays were carried out. Samples were collected in different localities (Sardinia, Italy) and hydro distilled. The yields ranged between 2.54% +/- 0.21 (v\\w dried weight) and 0.04% +/- 0.00. A total of 36 components were identified. The major compounds in the essential oils were alpha-pinene, beta-pinene, delta-3-carene, sabinene, myrcene, beta-phellandrene, limonene, and D-germacrene. Both qualitative and quantitative differences between species and between different parts of the plant were observed. The essential oils and their major compounds were tested against Candida albicans, Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, and the minimum inhibitory concentration and minimum bactericidal concentration were determined. The results obtained led to a nonsignificant inhibitory effect, although all the essential oils from Juniperus phoenicea ssp. turbinata and the essential oil from leaves of Juniperus oxycedrus ssp. oxycedrus exhibited rather good or weak activity against Candida albicans and Staphylococcus aureus.

Public Health Dental Hygienists in Massachusetts: A Qualitative Study.

PubMed

Rainchuso, Lori; Salisbury, Helen

2017-06-01

Purpose: The aim of this qualitative, phenomenological study was to explore the attitudes and perceptions of public health dental hygienists on providing preventive care to underserved populations in Massachusetts. Methods: Non-probability purposive sampling was used for initial participant recruitment, and snowball sampling occurred thereafter. Data collection occurred through semi-structured interviews. Qualitative analysis was conducted using Pitney and Parker's eight-step CREATIVE process. Results: Data saturation occurred with 10 participants (n=10), one-third of the public health dental hygienists who are practicing in Massachusetts. The majority of practice settings included school-based programs (70%), while programs for children with special needs (10%) were the least common. Two major themes emerged from the data; (a) the opportunity to be an oral health change agent and (b) barriers to practice. Six subcategories emerged from the data and are reviewed within the context of their associated themes. Additionally, career satisfaction emerged as an unintended theme, and was reported as the driving force for the majority of participants. Conclusion: This study revealed a better understanding of the public health dental hygiene workforce model in Massachusetts. Public health dental hygienists in Massachusetts perceive themselves as change agents within the health care profession, and although barriers to practice are plentiful, these oral health care professionals are committed to improving access to dental care.

Examination of coating failure by acoustic emission

NASA Technical Reports Server (NTRS)

Berndt, Christopher C.

1985-01-01

Coatings of NiCrAlY bond coat with a zirconia - 12 wt percent yttria overlay were applied to disc-shaped specimens of U-700 alloy. A waveguide of 1 mm diameter platinum was TIG welded to the specimen and allowed it to be suspended in a tubular furnace. The specimen was thermally cycled to 1150 C, and the acoustic emission (AE) monitored. The weight gain per thermal cycle was also measured. A computer system based on the IBM-XT microcomputer was used extensively to acquire the AE data with respect to temperature. This system also controlled the temperature by using a PD software loop. Several different types of AE analyses were performed. A major feature of these tests, not addressed by previous work in this area, was that the coatings covered 100 percent of the specimen and also that the AE was amplified at two different levels. It is believed that this latter feature allows a qualitative appraisal of the relative number of cracks per AE event. The difference in AE counts between the two channels is proportional to the number of cracks per AE event, and this parameter may be thought of as the crack density. The ratio of the AE count difference to the AE count magnitude of one channel is inversely proportional to the crack growth. Both of these parameters allow the crack distribution and crack growth within each specimen to be qualitatively followed during the thermal cycling operation. Recent results which used these principles will be presented.

2013-01-01

This qualitative study examines help-seeking pathways to depression care of low-income Latinos with diabetes and major depression. A purposive sample (N = 19) of Spanish-speaking, immigrant, low-income Latinos was selected from a randomized clinical trial targeting Latinos with diabetes and major depression. Four focus groups followed by 10 in-depth qualitative interviews were conducted. Narratives were analyzed using the constant comparative method informed by grounded theory. Need for formal care was described in relation to acute somatic symptoms, functional impairment, and mood changes. Treatment initiation occurred through family members and primary care physicians who encouraged or inhibited help-seeking. Adherence to depression care focused on interpersonal aspects of care, evaluated symptom relief, and improved functioning. Help-seeking barriers included self-reliance, language barriers, stigma, competing health demands, and structural barriers. Findings from this study highlight potential points of intervention for developing culturally-appropriate collaborative care approaches for low-income Latinos with diabetes and major depression.

Ellagitannins and ellagic acid conjugates are polyphenols present in the human diet, in particular strawberries (Fragaria spp.). The first aim of this study was isolation and structural characterization of casuarictin and 3-O-methyl ellagic acid 3'-O-α-rhamnopyranoside, which were found to be abundant in Fragaria spp., along with agrimoniin. The second aim was accurate profiling and quantification of 26 ellagitannins and ellagic acid conjugates in six Fragaria x ananassa cultivars and two Fragaria vesca species. The third aim was to describe the ellagitannins behavior during fruit ripening from the green stage to over-ripeness. It was shown that there are major qualitative and quantitative differences in the amount and profile of ellagitannins and ellagic acid conjugates between Fragaria spp. Genotype is a major factor in defining ellagitannin concentration and patterns between strawberries, and variable behavior of the genotypes was observed, in the context of a significant drop in ellagitannins during ripening.

to explore the nature of leadership styles used by the nursing management team, as perceived by nurses working at the bedside. leadership style is related to job satisfaction, staff retention, costs, and quality of care. The leadership styles of managers can be crucial in the healthcare setting, but very few studies have focused on them. the study employed qualitative methodology, involving 35 nurses working in different specialties of a medical city in Saudi Arabia. Data collection consisted of completing demographic and professional information and a semi-structured interview using open-ended questions. a phenomenologic-hermeneutic approach was used to identify major themes. the findings showed that participants described four types of leadership styles: relational leadership, preferential leadership, communication chain leadership, and ineffectual leadership. the leadership style employed by nurse managers has a major impact on nurses' satisfaction, turnover, and the quality of patient care they deliver.

From brain passage to cell adaptation: the road of human rabies vaccine development.

PubMed

Wu, Xianfu; Smith, Todd G; Rupprecht, Charles E

2011-11-01

A major challenge for global rabies prevention and control is the lack of sufficient and affordable high quality vaccines. Such candidates should be pure, potent, safe, effective and economical to produce, with broad cross-reactivity against viral variants of public health and veterinary importance. The history of licensed human vaccines reviewed herein demonstrates clearly how the field has evolved to the current state of more passive development and postexposure management. Modern cell culture techniques provide adequate viral substrates for production of representative verified virus seeds. In contrast to outdated nervous tissue-based rabies vaccines, once a suitable substrate is identified, production of high titer virus results in a major qualitative and quantitative difference. Given the current scenario of only inactivated vaccines for humans, highly cell-adapted and stable, attenuated rabies viruses are ideal candidates for consideration to meet the need for seed viruses in the future.

"Retirement lost"-the new role of the elderly as caretakers for orphans in Western Kenya.

Nyambedha, Erick O; Wandibba, Simiyu; Aagaard-Hansen, Jens

2003-03-01

A study on the new role of the elderly as caretakers of orphans was conducted in a rural part of Kenya applying a combination of qualitative and quantitative methods. One out of three children had lost at least one biological parent and one of nine had lost both. These figures are increasing exponentially. Most orphans were cared for by relatives, and about one out of five caretakers was 55 years of age or above. These elderly caretakers faced major difficulties in caring for the orphans in terms of schooling, food and medical care. There is a major difference between the present hardships of these caretakers and the traditional position of the elderly in the past. This dramatic deterioration in the situation of the elderly should be seen in the context of the rampant HIV/AIDS epidemic, population growth, changing socio-cultural values, and unfavourable macroeconomic trends.

Glenton, Claire; Oxman, Andrew D

2009-01-01

Objective To examine the use of qualitative approaches alongside randomised trials of complex healthcare interventions. Design Review of randomised controlled trials of interventions to change professional practice or the organisation of care. Data sources Systematic sample of 100 trials published in English from the register of the Cochrane Effective Practice and Organisation of Care Review Group. Methods Published and unpublished qualitative studies linked to the randomised controlled trials were identified through database searches and contact with authors. Data were extracted from each study by two reviewers using a standard form. We extracted data describing the randomised controlled trials and qualitative studies, the quality of these studies, and how, if at all, the qualitative and quantitative findings were combined. A narrative synthesis of the findings was done. Results 30 of the 100 trials had associated qualitative work and 19 of these were published studies. 14 qualitative studies were done before the trial, nine during the trial, and four after the trial. 13 studies reported an explicit theoretical basis and 11 specified their methodological approach. Approaches to sampling and data analysis were poorly described. For most cases (n=20) we found no indication of integration of qualitative and quantitative findings at the level of either analysis or interpretation. The quality of the qualitative studies was highly variable. Conclusions Qualitative studies alongside randomised controlled trials remain uncommon, even where relatively complex interventions are being evaluated. Most of the qualitative studies were carried out before or during the trials with few studies used to explain trial results. The findings of the qualitative studies seemed to be poorly integrated with those of the trials and often had major methodological shortcomings. PMID:19744976

Submegabase Clusters of Unstable Tandem Repeats Unique to the Tla Region of Mouse T Haplotypes

We describe here the identification and genomic organization of mouse t haplotype-specific elements (TSEs) 7.8 and 5.8 kb in length. The TSEs exist as submegabase-long clusters of tandem repeats localized in the Tla region of the major histocompatibility complex of all t haplotype chromosomes examined. In contrast, no such clusters were detected among 12 inbred strains of Mus musculus and other Mus species; thus, clusters of TSEs represent the first absolutely qualitative difference between t haplotypes and wild-type chromosomes. Pulsed field gel electrophoresis shows that the number of clusters, and the number of repeats in each cluster are extremely variable. Dramatic quantitative differences of TSEs uniquely distinguish every independent t haplotype from any other. The complete nucleotide sequence of one 7.8-kb TSE reveals significant homology to the ETn (a major transcript in the early embryo of the mouse), and some homologies to intracisternal A-particles and the mammary tumor virus env gene. Apart from the diagnostic relevance to t haplotypes, evolutionary and functional significances are discussed with respect to chromosome structure and genetic recombination. PMID:2076812

The essential-oil compositions of leaves, flowers, and rhizomes of Alpinia galanga (L.) Willd., Alpinia calcarata Rosc., Alpinia speciosa K. Schum., and Alpinia allughas Rosc. were examined and compared by capillary GC and GC/MS. Monoterpenoids were the major oil constituents identified. 1,8-Cineole, alpha-terpineol, (E)-methyl cinnamate, camphor, terpinen-4-ol, and alpha- and beta-pinenes were the major constituents commonly distributed in leaf and flower essential oils. The presence of endo-fenchyl acetate, exo-fenchyl acetate, and endo-fenchol was the unique feature of rhizome essential oils of A. galanga, A. calcarata, and A. speciosa. On contrary, the rhizome oil of A. allughas was dominated by beta-pinene. Significant qualitative and quantitative variations were observed in essential-oil compositions of different parts of Alpinia species growing in subtemperate and subtropical regions of Northern India. Cluster analysis was performed to find similarities and differences in essential-oil compositions based on representative molecular skeletons. Monoterpenoids, viz., 1,8-cineole, terpinen-4-ol, camphor, pinenes, (E)-methyl cinnamate, and fenchyl derivatives, were used as chemotaxonomic markers.

Red cotton bug, Dysdercus koenigii (Hemiptera: Pyrrhocoridae), has become the major insect pest of various crops, including cotton, and thereby reducing the yield qualitatively and quantitatively and synthetic insecticides belonging to different groups are the major control agents for such insect pests. A laboratory experiment was carried out to evaluate the effect of different conventional insecticides, i.e., imidacloprid, deltamethrin, lambda cyhalothrin, gamma cyhalothrin and cyfluthirn on haemocytes of D. koenigii. The individuals were exposed to insecticides separately and data was recorded after 30 and 60 min of the exposure. The findings of current study depicted chlorpyrifos to be more effective and significant alterations in total haemocyte counts and differential haemocyte counts were observed in the cyfluthirn treated D. koenigii. In addition to this, cell structure was also disrupted as an immune response. Similar studies would also be helpful to understand the defence mechanisms of insects against the xenobiotics which will help to device efficient management tools for D. koenigii.

In this cross-sectional study, the qualitative and quantitative throwing performance of male and female athletes (6 to 16 years of age) was analyzed. The goal of this study was to assess whether there were gender based qualitative and quantitative differences in throwing performance of young athletes, throughout three different age bands (childhood, pubescence, and adolescence). Furthermore, we explored whether all components of the throwing movement are equally affected by gender differences. Focus was placed on five essential components of action: trunk, forearm, humerus, stepping, and backswing. Therefore, children and adolescents (N = 96) were invited to throw three times from three different distances, while aiming at a target placed at shoulder height. The participants were aspiring athletes, competitive in the sport handball. For analyzing the quality of movement the component approach of Halverson and Roberton (1984) was used. The throwing accuracy was noted and used to evaluate the quantitative performance of the throwing movement. Throughout three different age bands, no statistically significant difference was found between genders in throwing accuracy, i.e., quantitative performance. Regarding the qualitative evaluation of the throwing movement, male and female athletes differed significantly. The component approach yielded higher scores for male than for female participants. As expected, with increasing age qualitative and quantitative performance of male and female athletes improved. These results suggest that there are gender-specific differences in qualitative throwing performance, but not necessarily in quantitative throwing performance. Exploration shows that differences in the qualitative throwing performance were seen in specific components of action. Male and female athletes demonstrated similar movement patterns in humerus and forearm actions, but differed in trunk, stepping, and backswing actions. PMID:28261142

Medical and business are one of the most popular majors among students, and both fields require intensive training to reach certain level of expertise. During the development of professionalism, goal can become a crucial role in psychological impetus. The purpose of this study is to compare goal contents, goal characteristics, and effect of goal characteristics on student's major satisfaction between medical and business. A total of 193 undergraduate students (97 medical students, 96 business students) answered survey questions including goal contents, goal characteristics (goal autonomy, goal attainability, social value of goal) and satisfaction on their majors. Qualitative analysis of goal contents and quantitative analysis of goal characteristics, and their effects on student major satisfaction were performed. Goal content analysis showed percentage of social concern goal was higher in medical students (25.8%) than business students (6.3%), whereas percentage of wealth goal was higher business students (24.0%) than medical students (3.1%). Among goal characteristics, goal attainability and social value of goal were higher in medical students than business students. In both groups, social value of goal was significantly predict major satisfaction. Goal contents and goal characteristics are different between medical and business students. Curriculum and educational interventions that concerning students' goal and developing programs to enhance students' social value of goal is necessary.

A threshold model of content knowledge transfer for socioscientific argumentation

Sadler, Troy D.; Fowler, Samantha R.

2006-11-01

This study explores how individuals make use of scientific content knowledge for socioscientific argumentation. More specifically, this mixed-methods study investigates how learners apply genetics content knowledge as they justify claims relative to genetic engineering. Interviews are conducted with 45 participants, representing three distinct groups: high school students with variable genetics knowledge, college nonscience majors with little genetics knowledge, and college science majors with advanced genetics knowledge. During the interviews, participants advance positions concerning three scenarios dealing with gene therapy and cloning. Arguments are assessed in terms of the number of justifications offered as well as justification quality, based on a five-point rubric. Multivariate analysis of variance results indicate that college science majors outperformed the other groups in terms of justification quality and frequency. Argumentation does not differ among nonscience majors or high school students. Follow-up qualitative analyses of interview responses suggest that all three groups tend to focus on similar, sociomoral themes as they negotiate socially complex, genetic engineering issues, but that the science majors frequently reference specific science content knowledge in the justification of their claims. Results support the Threshold Model of Content Knowledge Transfer, which proposes two knowledge thresholds around which argumentation quality can reasonably be expected to increase. Research and educational implications of these findings are discussed.

Racism at the intersections: Gender and socioeconomic differences in the experience of racism among African Americans.

PubMed

Kwate, Naa Oyo A; Goodman, Melody S

2015-09-01

Several studies investigating the health effects of racism have reported gender and socioeconomic differences in exposures to racism, with women typically reporting lower frequencies, and individuals with greater resources reporting higher frequencies. This study used diverse measures of socioeconomic position and multiple measures and methods to assess experienced racism. Socioeconomic position included education and financial and employment status. Quantitative racism measures assessed individual experiences with day-to-day and with major lifetime incidents and perceptions of the extent to which African Americans as a group experience racism. A brief qualitative question asked respondents to describe a racist incident that stood out in recent memory. Participants comprised a probability sample of N = 144 African American adults aged 19 to 87 residing in New York City. Results suggested that women reported fewer lifetime incidents but did not differ from men on everyday racism. These differences appear to be partly because of scale content. Socioeconomic position as measured by years of education was positively associated with reported racism in the total sample but differently patterned across gender; subjective social status showed a negative association. Qualitative responses describing memorable incidents fell into 5 key categories: resources/opportunity structures, criminal profiling, racial aggression/assault, interpersonal incivilities, and stereotyping. In these narratives, men were more likely to offer accounts involving criminal profiling, and women encountered incivilities more often. The findings highlight the need for closer attention to the intersection of gender and socioeconomic factors in investigations of the health effects of racism. (c) 2015 APA, all rights reserved).

Women's racial/ethnic-specific attitudes toward physical activity have been pointed out as a plausible reason for their low participation rates in physical activity. However, very little is actually known about racial/ethnic commonalities and differences in midlife women's attitudes toward physical activity. The purpose of this study was to explore commonalities and differences in midlife women's attitudes toward physical activity among 4 major racial/ethnic groups in the United States (whites, Hispanics, African Americans, and Asians). This was a secondary analysis of the qualitative data from a larger study that explored midlife women's attitudes toward physical activity. Qualitative data from 4 racial/ethnic-specific online forums among 90 midlife women were used for this study. The data were analyzed using thematic analysis, and themes reflecting commonalties and differences in the women's attitudes toward physical activity across the racial/ethnic groups were extracted. The themes reflecting the commonalities were: 1) physical activity is good for health, 2) not as active as I could be, 3) physical activity was not encouraged, 4) inherited diseases motivated participation in physical activity, and 5) lack of accessibility to physical activity. The themes reflecting the differences were: 1) physical activity as necessity or luxury, 2) organized versus natural physical activity, 3) individual versus family-oriented physical activity, and 4) beauty ideal or culturally accepted physical appearance. Developing an intervention that could change the social influences and environmental factors and address the women's racial/ethnic-specific attitudes would be a priority in increasing physical activity of racial/ethnic minority midlife women. © 2013 by the American College of Nurse-Midwives.

Implementation of a novel taxonomy based on cognitive work analysis in the assessment of safety performance.

Niskanen, Toivo

2017-12-12

The aim of this study was to examine how the developed taxonomy of cognitive work analysis (CWA) can be applied in combination with statistical analysis regarding different sociotechnical categories. This study applied a combination of quantitative and qualitative methodologies. Workers (n = 120) and managers (n = 85) in the chemical industry were asked in a questionnaire how different occupational safety and health (OSH) measures were being implemented. The exploration of the qualitative CWA taxonomy consisted of an analysis of the following topics: (a) work domain; (b) control task; (c) strategies; (d) social organization and cooperation; (e) worker competencies. The following hypotheses were supported - activities of the management had positive impacts on the aggregated variables: near-accident investigation and instructions (H 1 ); OSH training (H 2 ); operations, technical processes and safe use of chemicals (H 3 ); use of personal protective equipment (H 4 ); measuring, follow-up and prevention of major accidents (H 5 ). The CWA taxonomy was applied in mixed methods when testing H 1 -H 5 . A special approach is to analyze the work demands of complex sociotechnical systems with the taxonomy of CWA. In problem-solving, the CWA taxonomy should seek to capitalize on the strengths and minimize the limitations of safety performance.

Evaluating the Effects of Gamma-Irradiation for Decontamination of Medicinal Cannabis.

PubMed

Hazekamp, Arno

2016-01-01

In several countries with a National medicinal cannabis program, pharmaceutical regulations specify that herbal cannabis products must adhere to strict safety standards regarding microbial contamination. Treatment by gamma irradiation currently seems the only method available to meet these requirements. We evaluated the effects of irradiation treatment of four different cannabis varieties covering different chemical compositions. Samples were compared before and after standard gamma-irradiation treatment by performing quantitative UPLC analysis of major cannabinoids, as well as qualitative GC analysis of full cannabinoid and terpene profiles. In addition, water content and microscopic appearance of the cannabis flowers was evaluated. This study found that treatment did not cause changes in the content of THC and CBD, generally considered as the most important therapeutically active components of medicinal cannabis. Likewise, the water content and the microscopic structure of the dried cannabis flowers were not altered by standard irradiation protocol in the cannabis varieties studied. The effect of gamma-irradiation was limited to a reduction of some terpenes present in the cannabis, but keeping the terpene profile qualitatively the same. Based on the results presented in this report, gamma irradiation of herbal cannabis remains the recommended method of decontamination, at least until other more generally accepted methods have been developed and validated.

The effect of gamma-irradiation was limited to a reduction of some terpenes present in the cannabis, but keeping the terpene profile qualitatively the same. Based on the results presented in this report, gamma irradiation of herbal cannabis remains the recommended method of decontamination, at least until other more generally accepted methods have been developed and validated.

With the shift towards interprofessional education to promote collaborative practice, clinical preceptors are increasingly working with trainees from various professions to provide patient care. It is unclear whether and how preceptors modify their existing precepting approach when working with trainees from other professions. There is little information on strategies for this type of precepting, and how preceptors may foster or impede interprofessional collaboration. The purpose of this qualitative description pilot study was to identify current methods preceptors use to teach trainees from other professions in the clinical setting, particularly advanced practice nursing and medical trainees, and to identify factors that support or impede this type of precepting. Data collected through observations and interviews were analyzed by the research team using thematic analysis procedures. Three major themes were identified: 1) a variety of teaching approaches and levels of engagement with trainees of different professions, 2) preceptor knowledge gaps related to curricula, goals, and scope of practice of trainees from other professions, and 3) administrative, structural and logistical elements that impact the success of precepting trainees from different professions in the clinical setting. This study has implications for faculty development and evaluation of current precepting practices in clinical settings. Copyright © 2016 The Authors. Published by Elsevier Ltd..

We have investigated the basis of androgen resistance in seven unrelated individuals with complete testicular feminization or Reifenstein syndrome caused by single amino acid substitutions in the hormone-binding domain of the androgen receptor. Monolayer-binding assays of cultured genital skin fibroblasts demonstrated absent ligand binding, qualitative abnormalities of androgen binding, or a decreased amount of qualitatively normal receptor. The consequences of these mutations were examined by introducing the mutations by site-directed mutagenesis into the androgen receptor cDNA sequence and expressing the mutant cDNAs in mammalian cells. The effects of the amino acid substitutions on the binding of different androgens and on the capacity of the ligand-bound receptors to activate a reporter gene were investigated. Substantial differences were found in the responses of the mutant androgen receptors to incubation with testosterone, 5 alpha-dihydrotestosterone, and mibolerone. In several instances, increased doses of hormone or increased frequency of hormone addition to the incubation medium resulted in normal or near normal activation of a reporter gene by cells expressing the mutant androgen receptors. These studies suggest that the stability of the hormone receptor complex is a major determinant of receptor function in vivo. Images PMID:7929841

A comparison between findings from the DREEM questionnaire and that from qualitative interviews.

The Rural Clinical School of Western Australia educates one quarter of all Western Australian medical students in their first clinical year in rural settings. As part of a comprehensive evaluation programme students give feedback regularly. To identify if the Dundee Ready Education Environment Measurement (DREEM) data could be used qualitatively and descriptively to determine specific problems from the data alone despite the small numbers at some sites. The DREEM questionnaire was administered on the same day as qualitative interviews were undertaken. The qualitative interviews were analysed thematically first and then compared with findings from DREEM. Each major (student related) evaluation issue identified by the qualitative interviews was also identified by the DREEM questionnaire analysis. When the DREEM study was undertaken in the Rural Clinical School of Western Australia there was no real expectation that it would provide sufficient information to identify issues picked up in the extensive and time consuming qualitative study. About half of the work undertaken by the qualitative evaluation, that of the experiences of the students at the site, was picked up by the DREEM questionnaire in a much shorter time frame and at less cost of staff time and resources. The DREEM questionnaire can be used qualitatively to assess very specific issues relating to each of the subscales. These findings extend the use of DREEM from quantitative and statistically significant research to qualitative meaning-filled interpretations. The issues then need to be addressed sensitively.

Computerized PET/CT image analysis in the evaluation of tumour response to therapy

Wang, J; Zhang, H H

2015-01-01

Current cancer therapy strategy is mostly population based, however, there are large differences in tumour response among patients. It is therefore important for treating physicians to know individual tumour response. In recent years, many studies proposed the use of computerized positron emission tomography/CT image analysis in the evaluation of tumour response. Results showed that computerized analysis overcame some major limitations of current qualitative and semiquantitative analysis and led to improved accuracy. In this review, we summarize these studies in four steps of the analysis: image registration, tumour segmentation, image feature extraction and response evaluation. Future works are proposed and challenges described. PMID:25723599

This qualitative phenomenological study explores the lived experiences of perceived support by Iranian mothers who have children with learning disability. Twelve open interviews with six mothers of learning-disabled children (7-12 years of age) were audiotape-recorded with participants' consent. The interviews were transcribed and data were analyzed using Van Manen methodology. Two major themes emerged from 138 thematic sentences. The mothers'experiences could be interpreted as a sense of being in the light or being in the shade of support, with variations for different participants. The results indicate a need for more specialized and individually adjusted support for mothers in Iran.

Proton impact charge transfer on hydantoin - Prebiotic implications

2016-11-01

Formation and destruction of prebiotic compounds in astrophysical environments is a major issue in reactions concerning the origin of life. Detection of hydantoin in laboratory irradiation of interstellar ice analogues has confirmed evidence of this prebiotic compound and its stability to UV radiation or collisions may be crucial. Considering the different astrophysical environments, we have investigated theoretically proton-induced collisions with hydantoin in a wide energy range, from eV in the interstellar medium, up to keV for processes involving solar wind or supernovae shock-waves protons. Results are compared to previous investigations and qualitative trends on damage under spatial radiations are suggested.

We examined and contrasted 129 Canadian-born and immigrant women's experiences of violence and associated structural and interpersonal factors within indoor commercial sex venues. The majority experienced at least one form of structural, interpersonal, or both types of violence, with the attempted removal of a condom during sexual services being cited most frequently. Canadian-born women reported more frequent violent assaults in the survey data. The women's qualitative narratives illustrated that perceptions of violence differed significantly among Canadian versus non-Canadian born women. Findings concerning racialization and gendered relations of power have important implications for prevention and interventions to support victims of abuse.

Assessing the durability and efficiency of landscape-based strategies to deploy plant resistance to pathogens

PubMed Central

Rey, Jean-François; Barrett, Luke G.; Thrall, Peter H.

2018-01-01

Genetically-controlled plant resistance can reduce the damage caused by pathogens. However, pathogens have the ability to evolve and overcome such resistance. This often occurs quickly after resistance is deployed, resulting in significant crop losses and a continuing need to develop new resistant cultivars. To tackle this issue, several strategies have been proposed to constrain the evolution of pathogen populations and thus increase genetic resistance durability. These strategies mainly rely on varying different combinations of resistance sources across time (crop rotations) and space. The spatial scale of deployment can vary from multiple resistance sources occurring in a single cultivar (pyramiding), in different cultivars within the same field (cultivar mixtures) or in different fields (mosaics). However, experimental comparison of the efficiency (i.e. ability to reduce disease impact) and durability (i.e. ability to limit pathogen evolution and delay resistance breakdown) of landscape-scale deployment strategies presents major logistical challenges. Therefore, we developed a spatially explicit stochastic model able to assess the epidemiological and evolutionary outcomes of the four major deployment options described above, including both qualitative resistance (i.e. major genes) and quantitative resistance traits against several components of pathogen aggressiveness: infection rate, latent period duration, propagule production rate, and infectious period duration. This model, implemented in the R package landsepi, provides a new and useful tool to assess the performance of a wide range of deployment options, and helps investigate the effect of landscape, epidemiological and evolutionary parameters. This article describes the model and its parameterisation for rust diseases of cereal crops, caused by fungi of the genus Puccinia. To illustrate the model, we use it to assess the epidemiological and evolutionary potential of the combination of a major gene and different traits of quantitative resistance. The comparison of the four major deployment strategies described above will be the objective of future studies. PMID:29649208

Strangers in strange lands: a metasynthesis of lived experiences of immigrant asian nurses working in Western countries.

Nurses from Asian countries make up the majority of immigrant nurses globally. Although there are a limited number of studies on the lived experiences of Asian nurses working in Western countries, the development of nursing science will be impeded if the rich understanding gleaned from these studies is not synthesized. Using Noblit and Hare's (Meta-ethnography: Synthesizing Qualitative Studies. Newbury Park, Calif: Sage; 1988) procedures, a metasynthesis was conducted on 14 studies that met preset selection criteria. Four overarching themes emerged: (a) communication as a daunting challenge; (b) differences in nursing practice; (c) marginalization, discrimination, and exploitation; and (d) cultural differences. Based on the metasynthesis, a large narrative and expanded interpretation was constructed and implications for nursing knowledge development, clinical practice, and policy making are elaborated.

Qualitative research methods are increasingly used by nurse scientists to explore a wide variety of topics relevant to practice and/or health policy issues. The purpose of this chapter is to review the contributions of nurse scientists to the field of tobacco control through the use of qualitative research methods. A systematic literature search strategy was used to identify 51 articles published between 1980 and 2008. The majority (84%) of reviewed articles were authored by North American nurse scientists. Cessation was the most commonly (85%) studied aspect of tobacco control. Six qualitative research approaches were used: qualitative descriptive (55%), narrative analysis (8%), phenomenology (6%), grounded theory (14%), ethnography (12%), and case study (6%). Qualitative descriptive methods were primarily one-off studies to address practical problems or issues encountered in practice, and often validated current understandings related to tobacco. Researchers who used other types of qualitative methods and who conducted qualitative studies as part of programs of research were more likely to make more substantive contributions to the evolving field of tobacco control. These contributions related to how smoking intertwines with personal and social identities, the influence of social context on tobacco use, and nurses' involvement in tobacco control (both of their own tobacco use and in assisting others). Nurse scientists interested in exploring tobacco-related issues are encouraged to consider the full range of qualitative research approaches. Qualitative research methods contribute to our understanding of tobacco use arising from nursing practice, health care and policy, along with the field of tobacco control in general.

African-American professionals are underrepresented in the profession of dietetics. This preliminary qualitative study identified African-American students' perceptions of their majors, future professions, and the dietetics major/profession to understand why they did or did not enter dietetics. It was hypothesized that dietetics students chose dietetics primarily for altruistic reasons, whereas students in other fields of study did not choose dietetics due to lack of awareness of dietetics. To learn students' views, African-American college students engaged in elicitation interviews or focus group discussions. Twenty-eight women and 12 men participated. Phenomenologic analysis identified common themes and meanings: African-American students selected their majors for a variety of reasons, including desire to help people, interest in the field, recommendation from an adult, and family influence. African-American students in fields of study other than dietetics believed that the dietetics major was not selected due to lack of awareness about dietetics. Both dietetics students and students in other fields of study perceived versatility, ability to work with/help people, and to have an influence as positive qualities about their future professions. Advanced degree and training requirements, lack of diversity, and low salary were identified as negative qualities about future professions. African-American students in fields of study other than dietetics had not been exposed to the dietetics major, careers, and profession. Recruitment efforts should begin early to increase the number of African-American students in dietetics.

The experience of puberty in Iranian adolescent girls: a qualitative content analysis

2012-01-01

Background Adolescence is an important stage in human life span. Physiologic changes associated with puberty manifest themselves in often complex and bizarre ways to which girls show different reactions. This study aims to explore to puberty experiences in adolescent girls who live in the city of Sari in Iran. Methods The present study is a qualitative study of content analysis. Sampling took place in the city of Sari, Iran and was objective focused in accordance with qualitative studies. Participants were 38 girls of 12–20 years old who had at least experienced 3 menstrual cycles. Data was collected by means of focus group and in-depth interviews. Results As follows, Seven main themes were extracted from the interviews are follows: Menarche as the most unpleasant event in puberty, getting nervous about and ashamed of bodily changes, psychological changes, discordance with parents, sexual orientation and the need for education on this issue, scholastic dysfunction and religious considerations. Conclusion The results showed that for the majority of the participants puberty was an unpleasant experience. Most of them were in need of education on how to go about the issues surrounding puberty. The society, families and of course the adolescents themselves are responsible to work together in order to create an atmosphere in which correct information on puberty and the associated issues are readily accessible.

The Effect of Concept Mapping on Student Understanding and Correlation with Student Learning Styles

NASA Astrophysics Data System (ADS)

Mosley, William G.

This study investigated the use of concept mapping as a pedagogical strategy to promote change in the learning styles of pre-nursing students. Students' individual learning styles revealed two subsets of students; those who demonstrated a learning style that favors abstract conceptualization and those who demonstrated a learning style that favors concrete experience. Students in the experimental groups performed concept mapping activities designed to facilitate an integrative understanding of interactions between various organ systems of the body while the control group received a traditional didactic instruction without performing concept mapping activities. Both qualitative and quantitative data were collected in order to measure differences in student achievement. Analysis of the quantitative data revealed no significant change in the learning styles of students in either the control or experimental groups. Learning style groups were analyzed qualitatively for recurring or emergent themes that students identified as facilitating their learning. An analysis of qualitative data revealed that most students in the pre-nursing program were able to identify concepts within the class based upon visual cues, and a majority of these students exhibited the learning style of abstract conceptualization. As the laboratory experience for the course involves an examination of the anatomical structures of the human body, a visual identification of these structures seemed to be the most logical method to measure students' ability to identify anatomical structures.

A clinical diagnosis of epilepsy often carries a silent social stigma and is associated with metaphysical forces. This qualitative study aimed to explore the Iranian patients' perception of epilepsy where clinical aspects are more benign than the social implications with long-term psychological consequences. Historically, epilepsy has been known as a form of insanity, madness, sorcery, and possession by evil spirits. Thirty participants consisting of 21 patients with epilepsy, 5 family members, and 4 medical staff were selected from urban and rural medical and health care centers, hospitals, physician offices, outpatient clinics, and the Iranian Epilepsy Association. Unstructured and semistructured interviews were applied to obtain data. Transcribed interviews and field notes were analyzed using qualitative content analysis method. Categories and subcategories emerged from the participants' perceptions of epilepsy and its disruptive effects on their self-identity. The main categories derived from data were 1) a different perspective about epilepsy, 2) self-debasement, and 3) being a burden. The major theme found in this study was "identity loss". Our study results highlight the importance of public awareness among community members and healthcare professionals on how patients with epilepsy experience their disease with psychosocial implications. Understanding patients' perspectives can be essential to developing a comprehensive and holistic care plan for patients with epilepsy and addressing their multidimensional needs.

Qualitative research and the epidemiological imagination: a vital relationship.

PubMed

Popay, J

2003-01-01

This paper takes as its starting point the assumption that the 'Epidemiological Imagination' has a central role to play in the future development of policies and practice to improve population health and reduce health inequalities within and between states but suggests that by neglecting the contribution that qualitative research can make epidemiology is failing to deliver this potential. The paper briefly considers what qualitative research is, touching on epistemological questions--what type of "knowledge" is generated--and questions of methods--what approaches to data collection, analysis and interpretation are involved). Following this the paper presents two different models of the relationship between qualitative and quantitative research. The enhancement model (which assumes that qualitative research findings add something extra to the findings of quantitative research) suggests three related "roles" for qualitative research: generating hypothesis to be tested by quantitative research, helping to construct more sophisticated measures of social phenomena and explaining unexpected research from quantitative research. In contrast, the Epistemological Model suggests that qualitative research is equal but different from quantitative research making a unique contribution through: researching parts other research approaches can't reach, increasing understanding by adding conceptual and theoretical depth to knowledge, shifting the balance of power between researchers and researched and challenging traditional epidemiological ways of "knowing" the social world. The paper illustrates these different types of contributions with examples of qualitative research and finally discusses ways in which the "trustworthiness" of qualitative research can be assessed.

This paper proposes a qualitative model for the origin of the Utopia-Elysium northern lowlands on eastern Mars in terms of the long-term evolution of two large overlapping impact basins. The model, which is consistent with both the observed geologic constraints and more quantitative results obtained by numerical modeling of smaller (Orientale-size) impact basins, is shown to qualitatively account for the major topographic variation seen in the Utopia-Elysium region, including the overall 'lowness' of the area and localized depressions.

Complicating causality: patient and professional perspectives on obstetric fistula in Nigeria.

Phillips, Beth S; Ononokpono, Dorothy N; Udofia, Nsikanabasi W

2016-09-01

Obstetric fistula, a preventable maternal morbidity characterised by chronic bladder and/or bowel incontinence, is widespread in Nigeria. This qualitative, multi-site study examined the competing narratives on obstetric fistula causality in Nigeria. Research methods were participant observation and in-depth interviews with 86 fistula patients and 43 healthcare professionals. The study found that both patient and professional narratives identified limited access to medical facilities as a major factor leading to obstetric fistula. Patients and professionals beliefs regarding the access problem, however, differed significantly. The majority of fistula patients reported either delivering or attempting to deliver in medical facilities and most patients attributed fistula to a lack of trained medical staff and mismanagement at medical facilities. Conversely, a majority of health professionals believed that women developed obstetric fistula because they chose to deliver at home due to women's traditional beliefs about womanhood and childbirth. Both groups described financial constraints and inadequate transport to medical facilities during complicated labour as related to obstetric fistula onset. Programmatic insights derived from these findings should inform fistula prevention interventions both with healthcare professionals and with Nigerian women.

Studies have shown that research participants fail to appreciate the difference between research and medical care, labeling such phenomenon as a "therapeutic misconception" (TM). Since research activity involving human participants is increasing in the Middle East, qualitative research investigating aspects of TM is warranted. Our objective was to assess for the existence of therapeutic misconception amongst Egyptians. Study Tool: We developed a semi-structured interview guide to elicit the knowledge, attitudes, and perspectives of Egyptians regarding medical research. We recruited individuals from the outpatient settings (public and private) at Ain Shams University in Cairo, Egypt. Interviews were taped, transcribed, and translated. We analyzed the content of the transcribed text to identify the presence of a TM, defined in one of two ways: TM1 = inaccurate beliefs about how individualized care can be compromised by the procedures in the research and TM2 = inaccurate appraisal of benefit obtained from the research study. Our findings showed that a majority of participants (11/15) expressed inaccurate beliefs regarding the degree with which individualized care will be maintained in the research setting (TM1) and a smaller number of participants (5/15) manifested an unreasonable belief in the likelihood of benefits to be obtained from a research study (TM2). A total of 12 of the 15 participants were judged to have expressed a TM on either one of these bases. The presence of TM is not uncommon amongst Egyptian individuals. We recommend further qualitative studies investigating aspects of TM involving a larger sample size distinguished by different types of illnesses and socio-economic variables, as well as those who have and have not participated in clinical research.

Barriers and facilitators of help-seeking among unemployed persons with mental health problems: a qualitative study.

2017-01-17

Unemployed people with mental health problems often do not use mental health services and therefore do not benefit from available therapies. As unemployed individuals outside the healthcare system are a hard-to-reach group, barriers to and facilitators of mental health service use are poorly understood. The purpose of this study was to identify barriers to and facilitators of help-seeking and service use based on experiences of unemployed people with mental health problems. Fifteen qualitative semi-structured individual interviews were conducted with unemployed persons who reported mental health problems. Interview topics included individual experience with help-seeking and mental health service use with a focus on barriers and facilitators. Transcripts were analysed using qualitative content analysis and major themes were identified. Participants reported being treated as "different" within their social environment as well as by health care professionals because of their mental health problems, which resulted in a lack of self-esteem and avoidance of help-seeking. Interviewees associated negative attributes with help-seeking such as helplessness and weakness. They equated psychiatric medication with illegal drugs and worried about the risk of addiction. However, social support and a desire for change on the other hand increased the motivation to search for help. Employment agency staff were mostly perceived as supportive by individuals seeking mental health services. Unemployed individuals with mental health problems faced barriers and facilitators when seeking help on three different levels: (1) mental health literacy; (2) stigma and discrimination; and (3) structures and conditions of health care. Awareness and attitudes of health care professionals concerning mental health issues should be improved. Stigmatisation of people with mental illnesses should be reduced in health care settings. Training for employment agency staff concerning mental health problems and services is recommended.

The orbital evolution of NEA 30825 1900 TG1

Timoshkova, E. I.

2008-02-01

The orbital evolution of the near-Earth asteroid (NEA) 30825 1990 TG1 has been studied by numerical integration of the equations of its motion over the 100 000-year time interval with allowance for perturbations from eight major planets and Pluto, and the variations in its osculating orbit over this time interval were determined. The numerical integrations were performed using two methods: the Bulirsch-Stoer method and the Everhart method. The comparative analysis of the two resulting orbital evolutions of motion is presented for the time interval examined. The evolution of the asteroid motion is qualitatively the same for both variants, but the rate of evolution of the orbital elements is different. Our research confirms the known fact that the application of different integrators to the study of the long-term evolution of the NEA orbit may lead to different evolution tracks.

What Are the Lived Challenges Experienced by Black Females in a STEM Doctoral Program at a Majority White Institution?

Cleare, Sharlane S.

The purpose of this study is to explore the challenges experienced by Black female STEM doctoral students at a Majority White Institution. This study examined how, and to what extent did the Majority White Institution's STEM environment influenced such challenges. The qualitative phenomenological approach to this investigation utilized the lenses of Black Feminist Thought and Critical Race Feminism Theoretical Frameworks as interconnected lenses by which to conceptualize this phenomenon. This study answered the following question: What are the lived challenges experienced by Black female in a STEM doctoral program at a Majority White Institution? Purposeful and snowball sampling were employed to recruit participants for this investigation. Both sampling methods were selected because of their wide use in qualitative investigations, as well as their proven ability to precisely source quality participants (Biernacki, & Waldorf,1981; Palinkas, Horwitz, Green, Wisdom, Duan, & Hoagwood, (2015). Observations, in-depth semi-structured interviews, and focus groups were conducted with eleven (11) Black females STEM doctoral students currently studying at a large Majority White Institution in the Midwest. The findings from this study suggest that this is a phenomenon worthy of considerable attention. Research in the area of Black females in STEM doctoral programs at Majority White Institutions can be further expanded and updated. Therefore, this study will contribute and supplement existing literature on Black females in STEM doctoral programs at Majority White Institutions. Most importantly, the results obtained from this study can assist Majority White Institutions in the development and enhancement of programs and policies specifically geared towards addressing the needs of this underrepresented minority population segment.

Generational affinities and discourses of difference: a case study of highly skilled information technology workers.

2007-06-01

Sociologists theorizing the concept of 'generation' have traditionally looked to birth cohorts sharing major social upheavals such as war or decolonization to explain issues of generational solidarity and identity affiliation. More recently, theorists have drawn attention to the cultural elements where generations are thought to be formed through affinities with music or other types of popular culture during the 'coming of age' stage of life. In this paper, we ask whether developments in computer technology, which have both productive and cultural components, provide a basis for generational formation and identity and whether generational discourse is invoked to create cultures of difference in the workplace. Qualitative data from a sample of Information Technology workers show that these professionals mobilize 'generational' discourse and draw upon notions of 'generational affinity' with computing technology (e.g. the fact that people of different ages were immersed to varying degrees in different computing technologies) in explaining the youthful profile of IT workers and employees' differing levels of technological expertise.

Background: To respond efficiently to the increasing and new needs of people in health issues, it is necessary for nurses to develop their knowledge from hospital to society and to be equipped to play entrepreneur role in different levels of care. The present study was conducted to describe Iranian entrepreneur nurses’ perceived barriers to entrepreneurship, in order to identify the existing barriers. Materials and Methods: This is a qualitative study in which Graneheim and Lundman's content analysis method was employed. Thirteen entrepreneur nurses were chosen purposively, and data were gathered by unstructured interviews. Results: As a result of the data analysis, five major themes were extracted: Traditional nursing structure, legal limitations, traditional attitudes of governmental managers, unprofessional behaviors of colleagues, and immoral business. Conclusions: The findings of the present study show that Iranian nurses are confronted with various problems and barriers to enter entrepreneur nursing and keep going in this area. By focusing on such barriers and applying appropriate changes, policymakers and planners in health can facilitate nurses entering into this activity. PMID:26985222

Qualitative results are presented from analysis of volatile and semi-volatile organic compounds (VOCs/SVOCs) obtained through sampling of gaseous effluent and condensed particulates during a series of experimental house fires conducted in a real house. Particular emphasis is given to the 16 polycyclic aromatic hydrocarbons (PAHs) listed by the Environmental Protection Agency due to their potentially carcinogenic effects. The initial fuel packages were either cooking oil or a single sofa; these were burned both alone, and in furnished surroundings. Experiments were performed at different ventilation conditions. Qualitative Gas Chromatography-Mass Spectrometry (GC-MS) analysis found VOC/SVOC releases in the developing stages of the fires, and benzo(a)pyrene - the most carcinogenic PAH - was found in at least one sampling interval in the majority of fires. A number of phosphorus fire retardants were detected, in both the gaseous effluent and particulates, from fires where the initial fuel source was a sofa. Their release during the fire is significant as they pose toxicological concerns separate from those presented by the PAHs. Copyright © 2016. Published by Elsevier Ltd.

Healthcare quality improvement (QI) is a global priority, and understanding the perspectives of frontline healthcare workers can help guide sustainable and meaningful change. We report a qualitative investigation of emergency department (ED) staff priorities for QI at a tertiary care hospital in Ghana. The aims of the study were to educate staff about the World Health Organization's (WHO) definition of quality in healthcare, and to identify an initial focus for building a departmental QI program. Semi-structured interviews were conducted with ED staff using open-ended questions to probe their understanding and valuation of the six dimensions of quality defined by the WHO. Participants were then asked to rank the dimensions in order of importance for QI. Qualitative responses were thematically analyzed, and ordinal rank-order was determined for quantitative data regarding QI priorities. Twenty (20) members of staff of different cadres participated, including ED physicians, nurses, orderlies, a security officer, and an accountant. A majority of participants (61%) ranked access to emergency healthcare as high priority for QI. Two recurrent themes - financial accessibility and hospital bed availability - accounted for the majority of discussions, each linked to all the dimensions of healthcare quality. ED staff related all of the WHO quality dimensions to their work, and prioritized access to emergency care as the most important area for improvement. Participants expressed a high degree of motivation to improve healthcare quality, and the study helped with the development of a departmental QI program focused on the broad topic of access to ED services.

Breast cancer has become the most common cancer among Yazdi women in Iran. Thus, it is necessary to encourage these women to participate in breast health-seeking behaviors. In this regard, husbands can play an effective role. The aim of this study was to explore women's perceptions about the effect of their husband's role on breast health-seeking protection motivation. This study used a directed qualitative content analysis approach based on the Protection Motivation Theory. Participants were selected using purposive sampling; in-depth semistructured interviews with 14 Yazdi women were completed. One major category named "motivator role of husband" emerged from the analysis. The following subcategories underlying this category were "indifference and a lack of support as long as the women can continue with expected duties," "what women want for support," "facilitating and restrictive factors of husband's supportive role," "public health education needed," and "husband's agreement with preventive actions." Voluntary participation in breast health-seeking behaviors is a culturally sensitive topic. The qualitative methodology allowed this sensitive topic and its different aspects to be explored. The findings indicated that the major source of support for women was their husband's behavior toward breast health-seeking actions. Family cohesion and love among couples were identified as strong determinant factors pertaining to husband's supportive behaviors. The study findings provided deeper understanding about the effective factors related to a husband's role in motivating a wife to practice breast cancer prevention. These new findings are relevant for health educators and practitioners to develop culturally based interventions.

The authors aimed to map and explicate what surgeons perceive they learn in the operating room. The researchers used a grounded theory method in which data were iteratively collected through semistructured one-to-one interviews in 2010 and 2011 at four participating hospital sites. A four-person data analysis team from differing academic backgrounds qualitatively analyzed the content of the transcripts employing an immersion/crystallization approach. Participants were 22 UK surgeons, some of whom were in training at the time of the study and some of whom were attending surgeons. Major themes of learning in the operating room were perceived to be factual knowledge, motor skills, sensory semiosis, adaptive strategies, team working and management, and attitudes and behaviors. The analysis team classified 277 data points (short paragraphs or groups of sentences conveying meaning) under these major themes and subthemes. A key component of learning in the operating room that emerged from these data was sensory semiosis, defined as learning to make sense of visual and haptic cues. Although the authors found that learning in the operating room occurred across a wide range of domains, sensory semiosis was found to be an important theme that has not previously been fully acknowledged or discussed in the surgical literature. The discussion draws on the wider literature from the social sciences and cognitive psychology literature to examine how professionals learn to make meaning from "signs" making parallels with other medical specialties.

This article is a report of a systematic review and meta-ethnography of women's experience of menarche. Adolescents may experience menarche at different ages, but menarche remains an important milestone in the female maturation process, representing the transition from childhood to womanhood. Systematic review and meta-ethnography. Electronic databases were systematically searched and supplemented with reference lists searching. Qualitative studies of women's experience of menarche were purposely selected and questions proposed by the critical appraisal skills programme was adapted and used to assess papers prior to synthesis. Key themes and concepts were extracted and synthesised using meta-ethnography. Fourteen studies on menarche experience were identified. The majority of studies were descriptive. Five key concepts were identified from all 14 papers as being descriptive of women's experience of menarche. These included: menarche preparation, significant others' response to menarche, physical experience of menarche, psychological experience of menarche and social-cultural perspective of menarche. Menarche experience had a major impact on women. Women went through physical, psychological and social-culture changes when their first menstrual flow came. Menarche preparation has been shown to have a beneficial impact on the menarcheal woman. School nurses have accurate knowledge about sexual health; they can and should provide appropriate menstrual education. The findings can be used by school nurses working with adolescents as the basis for a framework of intervention strategies directed towards helping adolescents to better accept their menarche and transition into womanhood.

In cheese, lactic acid bacteria are immobilized at the coagulation step and grow as colonies. The spatial distribution of bacterial colonies is characterized by the size and number of colonies for a given bacterial population within cheese. Our objective was to demonstrate that different spatial distributions, which lead to differences in the exchange surface between the colonies and the cheese matrix, can influence the ripening process. The strategy was to generate cheeses with the same growth and acidification of a Lactococcus lactis strain with two different spatial distributions, big and small colonies, to monitor the production of the major ripening metabolites, including sugars, organic acids, peptides, free amino acids, and volatile metabolites, over 1 month of ripening. The monitored metabolites were qualitatively the same for both cheeses, but many of them were more abundant in the small-colony cheeses than in the big-colony cheeses over 1 month of ripening. Therefore, the results obtained showed that two different spatial distributions of L. lactis modulated the ripening time course by generating moderate but significant differences in the rates of production or consumption for many of the metabolites commonly monitored throughout ripening. The present work further explores the immobilization of bacteria as colonies within cheese and highlights the consequences of this immobilization on cheese ripening.

Beliefs and perception about mental health issues: a meta-synthesis

PubMed Central

Choudhry, Fahad Riaz; Mani, Vasudevan; Ming, Long Chiau; Khan, Tahir Mehmood

2016-01-01

Background Mental health literacy is the beliefs and knowledge about mental health issues and their remedies. Attitudes and beliefs of lay individuals about mental illness are shaped by personal knowledge about mental illness, knowing and interacting with someone living with mental illness, and cultural stereotypes. Mental health issues are increasing and are alarming in almost every part of the world, and hence compiling this review provides an opportunity to understand the different views regarding mental disorders and problems as well as to fill the gap in the published literature by focusing only on the belief system and perception of mental health problems among general population. Method The methodology involved a systematic review and the meta-synthesis method, which includes synthesizing published qualitative studies on mental health perception and beliefs. Sample Fifteen relevant published qualitative and mixed-method studies, regarding the concept of mental health, were identified for meta-synthesis. Analysis All the themes of the selected studies were further analyzed to give a broader picture of mental health problems and their perceived causes and management. Only qualitative studies, not older than 2010, focusing on beliefs about, attitudes toward, and perceptions of mental health problems, causes, and treatments were included in this review. Results The findings are divided into four major categories, namely, 1) symptoms of mental health issues, 2) description of mental health issues, 3) perceived causes, and 4) preferred treatment and help-seeking behavior. Each category contains themes and subthemes based on published studies. Conclusion The findings reveal multiple causes of, descriptions of, and treatment options for mental health problems, thereby providing insight into different help-seeking behaviors. Clarity is offered by highlighting cultural differences and similarities in mental health beliefs and perceptions about the causes of mental health problems. The implications of the studies and recommendations based on current findings are also discussed. PMID:27826193

The authors conducted validity testing of the 5 major reported indices for radiosurgically treated brain metastases- the original Radiation Therapy Oncology Group's Recursive Partitioning Analysis (RPA), the Score Index for Radiosurgery in Brain Metastases (SIR), the Basic Score for Brain Metastases (BSBM), the Graded Prognostic Assessment (GPA), and the subclassification of RPA Class II proposed by Yamamoto-in nearly 2500 cases treated with Gamma Knife surgery (GKS), focusing on the preservation of neurological function as well as the traditional endpoint of overall survival. The authors analyzed data from 2445 cases treated with GKS by the first author (T.S.), the primary surgeon. The patient group consisted of 1716 patients treated between January 1998 and March 2008 (the Chiba series) and 729 patients treated between April 2008 and December 2011 (the Tokyo series). The interval from the date of GKS until the date of the patient's death (overall survival) and impaired activities of daily living (qualitative survival) were calculated using the Kaplan-Meier method, while the absolute risk for two adjacent classes of each grading system and both hazard ratios and 95% confidence intervals were estimated using the Cox proportional hazards model. For overall survival, there were highly statistically significant differences between each two adjacent patient groups characterized by class or score (all p values < 0.001), except for GPA Scores 3.5-4.0 and 3.0. The SIR showed the best statistical results for predicting preservation of neurological function. Although no other grading systems yielded statistically significant differences in qualitative survival, the BSBM and the modified RPA appeared to be better than the original RPA and GPA. The modified RPA subclassification, proposed by Yamamoto, is well balanced in scoring simplicity with respect to case number distribution and statistical results for overall survival. However, a new or revised grading system is necessary for predicting qualitative survival and for selecting the optimal treatment for patients with brain metastasis treated by GKS.

The occurrence of 'what', 'where', 'what house' and other repair initiations in the home environment of hearing-impaired individuals.

Even though research has increasingly focused on the qualitative features of natural conversations, which have improved the communication therapy for hearing-impaired individuals (HI) and familiar partners (FP), very little is known about the interactions that occur outside clinical settings. This study investigated qualitatively how both HI and FP initiated repair due to misperceptions or to a difficulty in understanding during conversations conducted at home. The HI participant's multimodal production style was adopted in the present analysis, and the frequencies were calculated for the different types of verbal repair initiations. Participants with acquired hearing loss (43-69 years) and their familiar partners (24-67 years) were video recorded (total time approximately 9 h) in their homes. The data consisted of eight conversational dyads. The transcription and analysis utilized Conversation Analysis. A total of 209 (HI 164/FP 45) verbal repair initiations were identified. The five major types of initiations found in the data (used by both HI and FP) were: open repair initiation, targeting question word, question word with repetition, repetition, and candidate understanding. HI participants rarely explicitly verbalized their difficulty to hear, but the production style, which included a fast speech rate and 'trouble posture', indicated a sensitive routine that was visible particularly in clear misperceptions. Furthermore, the alerting action of overlapping turn taking with the FP participant's turn could be seen to reveal the depth of misperception. The individual differences between HI participants were found predominantly in the frequency of their repair initiations, but also in how they used the different types of repair initiation. Through a deeper qualitative analysis, conversational research can provide extended knowledge of the occurrence and style of ordinary repair initiations and highlight their relationship in certain conversational environments. A robust starting point in communication therapy is increasing the awareness of HI individuals' existing skills. © 2012 Royal College of Speech and Language Therapists.

Smoking is a major cardiovascular risk factor, and smoking cessation is imperative for patients hospitalized with a cardiovascular event. This study aimed to evaluate a systems-based approach to helping hospitalized smokers quit and to identify implementation barriers. Prospective intervention study followed by qualitative analysis of staff interviews. The prospective intervention study assessed the effects of implementing standard operating procedures (SOPs) for the provision of counselling and pharmacotherapy to smokers admitted to cardiology wards on counselling frequency. In addition, a qualitative analysis of staff interviews was undertaken to examine determinants of physician and nurse behaviour; this sought to understand barriers in terms of motivation, capability, and/or opportunity. A total of 150 smoking patients were included in the study (75 before and 75 after SOP implementation). Before the implementation of SOPs, the proportion of patients reporting to have received cessation counselling from physicians and nurses was 6.7% and 1.3%, respectively. Following SOP implementation, these proportions increased to 38.7% (p < 0.001) and 2.7% (p = 0.56), respectively. Qualitative analysis revealed that lack of motivation, e.g. role incongruence, appeared to be a major barrier. Introduction of a set of standard operating procedures for smoking cessation advice was effective with physicians but not nurses. Analysis of barriers to implementation highlighted lack of motivation rather than capability or opportunity as a major factor that would need to be addressed. © The European Society of Cardiology 2012.

This qualitative investigation explored a relatively understudied aspect of cultural diversity: feminism and religion in the lives of religiously diverse women. More specifically, structured interviews were used to investigate views of religion, women's issues, gender roles, culture, and feminism for a small group of Muslim and Christian women living in the United States. The data were analyzed using consensual qualitative research methods (Hill, Thompson, & Williams, 1997). Findings indicated a complex relationship between feminism, gender roles, culture, and religion for these women with the majority of the Muslim women reporting that their religion supports feminist principles and identifying themselves as feminist. Christian women were less willing to endorse the feminist label. Implications for multicultural feminist practice are discussed. 2008 APA

In their comments on Hall, Yip, and Zárate (2016), Dvorakova (2016) addresses cultural psychology methods and Yakushko, Hoffman, Consoli, and Lee (2016) address qualitative research methods. We provide evidence of the neglect of underrepresented groups in the publications of major journals in cultural psychology and qualitative psychology. We do not view any particular research method as inherently contributing to "epistemological violence" (Yakushko et al., 2016, p. 5), but it is the misguided application and/or interpretation of data generated from such methods that perpetuate oppression. We contend that best practices for representing ethnocultural diversity in research will require a diverse toolbox containing quantitative, qualitative, biological, and behavioral approaches.

In this substudy of the Measurement and Treatment Research to Improve Cognition in Schizophrenia we examined qualitative feedback on the cross-cultural adaptability of four intermediate measures of functional outcome (Independent Living Scales, UCSD Performance-Based Skills Assessment, Test of Adaptive Behavior in Schizophrenia, and Cognitive Assessment Interview). Feedback was provided by experienced English-fluent clinical researchers at 31 sites in eight countries familiar with medication trials. Researchers provided feedback on test subscales and items which were rated as having adaptation challenges. They noted the specific concern and made suggestions for adaptation to their culture. We analyzed the qualitative data using a modified Grounded Theory approach guided by the International Testing Commission Guidelines model for test adaptation. For each measure except the Cognitive Assessment Interview (CAI), the majority of subscales were reported to require major adaptations in terms of content and concepts contained in the subscale. In particular, social, financial, transportation and health care systems varied widely across countries-systems which are often used to assess performance capacity in the U.S. We provide suggestions for how to address future international test development and adaptation.

To discuss issues in the theorization and study of gender observed during a qualitative meta-synthesis of influences on uptake of secondary prevention and cardiac rehabilitation services. Women and men can equally benefit from secondary prevention/cardiac rehabilitation and there is a need to understand gender barriers to uptake. Meta-method analysis secondary to meta-synthesis. For the meta-synthesis, a systematic search was performed to identify and retrieve studies published as full papers during or after 1995 and contained: a qualitative research component wholly or in a mixed method design, extractable population specific data or themes for referral to secondary prevention programmes and adults ≥18 years. Databases searched between January 1995-31 October 2011 included: CSA Sociological Abstracts, EBSCOhost CINAHL, EBSCOhost Gender Studies, EBSCOhost Health Source Nursing: Academic Edition, EBSCOhost SPORTDiscus, EBSCOhost SocINDEX. Studies were reviewed against inclusion/exclusion criteria. Included studies were subject to quality appraisal and standardized data extraction. Of 2264 screened articles, 69 were included in the meta-method analysis. Only four studies defined gender or used gender theories. Findings were mostly presented as inherently the characteristic of gendered worldviews of participants. The major themes suggest a mismatch between secondary prevention/cardiac rehabilitation services and consumers' needs, which are usually portrayed as differing according to gender but may also be subject to intersecting influences such as age or socioeconomic status. There is a persistent lack of theoretically informed gender analysis in qualitative literature in this field. Theory-driven gender analysis will improve the conceptual clarity of the evidence base for gender-sensitive cardiac rehabilitation programme development. © 2015 John Wiley & Sons Ltd.

A Qualitative Study of Violence Against Women after the Recent Disasters of Iran.

2016-08-01

Introduction Violence against women (VAW) is one of the most widespread violations of human rights and a major barrier to achieving gender equality. Violence against women is increased in disaster-stricken communities. Violence experiences, cases, and lessons-learned concerning Iran's disasters have not been investigated, documented, or shared so far. To fill this knowledge gap, this qualitative study aimed to explore types of VAW and girls after the recent quakes and floods in Iran. Problem The objective for this study was exploring the manifestations of VAW after the natural disasters in Iran. A qualitative approach was used for this study. Data were collected by in-depth, unstructured interviews and field observations in three affected regions of Iran, including East Azerbaijan, Bushehr, and Mazandaran. A total of 15 participants, eight damaged women as well as seven key informants, were interviewed. A content analysis using Graneheim approach was performed for analyzing transcribed interviews. Two main themes were extracted from data, including domestic violence and violence within community. The first theme included three categories: physical, psychological, and sexual violence. Psychological violence and sexual harassment were two categories of violence within the community concept. Different types of violence emerged from the present research that can be anticipated and integrated into future disaster medicine plans, public health reforms, and national rules of Iran. Improving women's knowledge on their rights to have a life without violence, and participation of both women and men in violence reduction projects, can be considered in all disaster management phases.

Background The period of hospital stay and the first month after discharge have been found to be the most problematic stages for family caregivers of stroke survivors. It is just at home that patients and caregivers actually understand the whole consequences of the stroke. The adult offspring often have more different needs and concerns than spousal caregivers. However, relatively little attention has been paid to the needs of this particular group of caregivers. Therefore, this qualitative content analysis study aimed to explore the supportive needs and coping behaviors of daughter and daughter in-law caregivers (DILs) of stroke survivors one month after the patient’s discharge from the hospital in Shiraz, Southern of Iran. Methods This is a qualitative content analysis study using semi-structured and in-depth interviews with a purposive sampling of seventeen daughter and daughter in-law caregivers. Results The data revealed seven major themes including information and training, financial support, home health care assistance need, self-care support need, adjusting with the cultural obligation in providing care for a parent in-law, and need for improving quality of hospital care. Also, data from the interview showed that daughter and daughter in-law caregivers mostly used emotional-oriented coping strategies, specially religiosity, to cope with their needs and problems in their care-giving role. Conclusion The results of this qualitative study revealed that family caregivers have several unmet needs in their care-giving role. By providing individualized information and support, we can prepare these family caregivers to better cope with the home care needs of stroke survivors and regain control over aspects of life.

Observations on positivism and pseudoscience in qualitative nursing research.

PubMed

Johnson, M

1999-07-01

In this paper I will examine the boundaries between positivism, interpretivism and pseudoscience, arguing that some qualitative researchers may risk the credibility of nursing research by utilizing concepts from the margins of science. There are two major threats to the perceived rigour and credibility of qualitative research in its many forms. First is a trend in some work towards a mystical view of both the methods and the content of the qualitative enterprise. This can be detected, I will argue, in the work of Rosemary Parse in particular. The second potentially damaging trend is almost its epistemological opposite, towards excessive reliance on precise procedures, strict definitions and verification exemplified by Juliet Corbin and others. I will suggest that this is nothing to fear, but something to be clear about. This is not social constructionism or interpretivism but a 'qualitative' version of positivism. The paper concludes that students and researchers should be cautious in the uncritical acceptance of theories and 'research' which approach the boundaries of pseudoscience on the one hand, and 'hard' science on the other.

The purpose of this study was to explore variations in how contemporary couples from five different Asian regions negotiate disagreements. Video recordings of 50 couples (10 each from Japan, Korea, Mainland China, Taiwan, and Hong Kong) discussing unresolved disagreements provided raw data for quantitative and qualitative analyses. First, teams of coders from each region used a common protocol to make quantitative ratings of content themes and interaction patterns for couples from their own region. An interregional panel of investigators then performed in-depth qualitative reviews for half of these cases, noting cultural differences not only in observed patterns of couple behavior but also in their own perceptions of these patterns. Both quantitative and qualitative analyses revealed clear regional differences on dimensions such as overt negativity, demand-withdraw interaction, and collaboration. The qualitative results also provided a richer, more nuanced view of other (e.g., gender-linked) conflict management patterns that the quantitative analyses did not capture. Inconsistencies between qualitative and quantitative data and between the qualitative observations of investigators from different regions were most pronounced for couples from Korea and Japan, whose conflict styles were subtler and less direct than those of couples from the other regions. © FPI, Inc.

Methods for assessing geodiversity

NASA Astrophysics Data System (ADS)

Zwoliński, Zbigniew; Najwer, Alicja; Giardino, Marco

2017-04-01

The accepted systematics of geodiversity assessment methods will be presented in three categories: qualitative, quantitative and qualitative-quantitative. Qualitative methods are usually descriptive methods that are suited to nominal and ordinal data. Quantitative methods use a different set of parameters and indicators to determine the characteristics of geodiversity in the area being researched. Qualitative-quantitative methods are a good combination of the collection of quantitative data (i.e. digital) and cause-effect data (i.e. relational and explanatory). It seems that at the current stage of the development of geodiversity research methods, qualitative-quantitative methods are the most advanced and best assess the geodiversity of the study area. Their particular advantage is the integration of data from different sources and with different substantive content. Among the distinguishing features of the quantitative and qualitative-quantitative methods for assessing geodiversity are their wide use within geographic information systems, both at the stage of data collection and data integration, as well as numerical processing and their presentation. The unresolved problem for these methods, however, is the possibility of their validation. It seems that currently the best method of validation is direct filed confrontation. Looking to the next few years, the development of qualitative-quantitative methods connected with cognitive issues should be expected, oriented towards ontology and the Semantic Web.

Social phobia and avoidant personality disorder: similar but different?

PubMed

Lampe, Lisa; Sunderland, Matthew

2015-02-01

Avoidant personality disorder (AvPD) is regarded as a severe variant of social phobia (SP), consistent with a dimensional model. However, these conclusions are largely drawn from studies based on individuals with SP, with or without comorbid AvPD. The present study hypothesized that there are qualitative differences between AvPD and SP that are undermined by limiting research to participants with SP. The authors sought to test this hypothesis by comparing three groups-SP only, AvPD only, and SP+AvPD-using data extracted from an epidemiological sample of 10,641 adults aged 18 years and over. Screening questions were used in the epidemiological survey to identify ICD-10 personality disorders; from this the author developed a proxy measure for DSM-IV AvPD. Axis I diagnoses, including DSM-IV SP, were identified using the Composite International Diagnostic Interview (CIDI). In this sample, the majority of those with AvPD did not also have SP: The authors found 116 persons with AvPD only, 196 with SP only, and 69 with SP+AvPD. There was little difference between any of the groups on sex, marital status, employment, education, or impairment variables. The SP+AvPD group reported more distress and comorbidity than the SP only and AvPD only groups, which did not differentiate from each other. More feared social situations were endorsed in the SP only group compared to the AvPD only group. Although the finding of few differences between SP only and AvPD only groups among the variables measured in this epidemiological survey fails to provide support for the hypothesis of qualitative differences, the finding that the AvPD only group appears more similar to the SP only group than to the SP+AvPD group also fails to provide support for the alternative continuity hypothesis. The greater distress and additional comorbidity with depression associated with SP+AvPD may be due to the additional symptom load of a second disorder rather than simply representing a more severe variant of social phobia. The use of a proxy for AvPD is a limitation of the study. Future studies should focus on broader clinical variables that have been proposed as qualitatively different between these disorders, and on the possible genetic and environmental factors that might help explain such differences.

The majority of schools in the Asia-Pacific region have adopted medical curricula based on western pedagogy. However to date there has been minimal exploration of the influence of the culture of learning on the teaching and learning process. This paper explores this issue in relation to clinical reasoning. A comparative case study was conducted in 2 medical schools in Australia (University of Melbourne) and Asia (Universitas Indonesia). It involved assessment of medical students' attitudes to clinical reasoning through administration of the Diagnostic Thinking Inventory (DTI), followed by qualitative interviews which explored related cultural issues. A total of 11 student focus group discussions (45 students) and 24 individual medical teacher interviews were conducted, followed by thematic analysis. Students from Universitas Indonesia were found to score lower on the Flexibility in Thinking subscale of the DTI. Qualitative data analysis based on Hofstede's theoretical constructs concerning the culture of learning also highlighted clear differences in relation to attitudes to authority and uncertainty avoidance, with potential impacts on attitudes to teaching and learning of clinical reasoning in undergraduate medical education. Different attitudes to teaching and learning clinical reasoning reflecting western and Asian cultures of learning were identified in this study. The potential impact of cultural differences should be understood when planning how clinical reasoning can be best taught and learned in the changing global contexts of medical education, especially when the western medical education approach is implemented in Asian contexts.

It's All in the Lens: Differences in Views on Obesity Prevention between Advocates and Policy Makers

Abstract Background: Intervention strategies to reduce obesity include policy and environmental changes that are designed to provide opportunities, support, and cues to help people develop healthier behaviors. Policy changes at the state level are one way to influence access, social norms, and opportunities for better nutrition and increased physical activity among the population. Methods: Ten states were selected for a broad variance in obesity rates and number of enacted obesity prevention policies during the years of 2006–2009. Within the selected states, a purely qualitative study of attitudes of childhood obesity policy using semistructured telephone interviews was conducted. Interviews were conducted with state policy makers who serve on public health committees. A set of six states that had more than eight childhood obesity policies enacted were selected for subsequent qualitative interviews with a convenience sample of well-established advocates. Results: Policy makers in states where there was more childhood obesity policy action believed in the evidence behind obesity policy proposals. Policy makers also varied in the perception of obesity as a constituent priority. The major differences between advocates and policy makers included a disconnect in information dissemination, opposition, and effectiveness of these policies. Conclusions: The findings from this study show differences in perceptions among policy makers in states with a greater number of obesity prevention bills enacted. There are differences among policy makers and advocates regarding the role and effectiveness of state policy on obesity prevention. This presents an opportunity for researchers and practitioners to improve communication and translation of evidence to policy makers, particularly in states with low legislation. PMID:22799551

Assigning poetry reading as a way of introducing students to qualitative data analysis.

PubMed

Raingruber, Bonnie

2009-08-01

The aim of the paper is to explain how poetry reading can be used to teach interpretive analysis of qualitative data. A number of studies were located in the nursing literature that focused on using poetry to help students develop empathy for patients, to teach students to reflect on their own practice, and to assist them in developing self-understanding. No studies were found that described the use of poetry reading as a way of teaching the skill of interpretive analysis. There are, however, a number of parallels between the principles of poetry reading and qualitative analysis that suggest that this method of teaching would be successful. International papers published on PubMed, Medline, and CINAHL were reviewed to identify challenges facing educators and ways of teaching the process of qualitative data analysis using poetry reading. Using poetry reading to teach skills of qualitative data analysis helps motivate students, cultivates a reflective mindset, and develops the skill of working as a member of an interpretive group. Framing interpretive work as being like reading poetry helps students pick up more quickly on the art that is a major component of the work. This approach also helps students learn the importance of cultural and contextual particulars as they begin analyzing qualitative data. Using poetry reading to introduce students to the complex skill of qualitative data analysis is an effective pedagogical strategy.

Natural enamel caries in polarized light microscopy: differences in histopathological features derived from a qualitative versus a quantitative approach to interpret enamel birefringence.

2012-05-01

Lesion area measurement of enamel caries using polarized light microscopy (PLM) is currently performed in a large number of studies, but measurements are based mainly on a mislead qualitative interpretation of enamel birefringence in a single immersion medium. Here, five natural enamel caries lesions are analysed by microradiography and in PLM, and the differences in their histopathological features derived from a qualitative versus a quantitative interpretation of enamel birefringence are described. Enamel birefringence in different immersion media (air, water and quinoline) is interpreted by both qualitative and quantitative approaches, the former leading to an underestimation of the depth of enamel caries mainly when the criterion of validating sound enamel as a negatively birefringent area in immersion in water is used (a current common practice in dental research). Procedures to avoid the shortcomings of a qualitative interpretation of enamel birefringence are presented and discussed. © 2012 The Authors Journal of Microscopy © 2012 Royal Microscopical Society.

Work environment is believed to be a major factor for better performance of human resource for health in any organization. This study concentrated on multiple factors involved in job satisfaction was appraised to critique their efficient significance in calculation of the health professional liking. Factors included job matched with workers' skills/experience, incentives, supervision, administrator support; convenient work load, training, appreciation, low pay and job protection were major contributors in job satisfaction. A mix method study was done in 2014; an initial descriptive cross sectional survey was done followed by qualitative approach. Eighteen in-depth interviews with health care providers were conducted after taking written consent. Nodes, sub-nodes and final themes were generated during qualitative data analysis. Main findings and themes were, generated after making the nodes and sub-nodes from the most frequent responses. These themes were; absence of work pressure, work place safety, social support, learning opportunities, and employee influence on conditions and recognition individual or team efforts. Work environment is a major contributing factor towards job satisfaction among the health workers.

When mixed methods produce mixed results: integrating disparate findings about miscarriage and women's wellbeing.

PubMed

Lee, Christina; Rowlands, Ingrid J

2015-02-01

To discuss an example of mixed methods in health psychology, involving separate quantitative and qualitative studies of women's mental health in relation to miscarriage, in which the two methods produced different but complementary results, and to consider ways in which the findings can be integrated. We describe two quantitative projects involving statistical analysis of data from 998 young women who had had miscarriages, and 8,083 who had not, across three waves of the Australian Longitudinal Study on Women's Health. We also describe a qualitative project involving thematic analysis of interviews with nine Australian women who had had miscarriages. The quantitative analyses indicate that the main differences between young women who do and do not experience miscarriage relate to social disadvantage (and thus likelihood of relatively early pregnancy) and to a lifestyle that makes pregnancy likely: Once these factors are accounted for, there are no differences in mental health. Further, longitudinal modelling demonstrates that women who have had miscarriages show a gradual increase in mental health over time, with the exception of women with prior diagnoses of anxiety, depression, or both. By contrast, qualitative analysis of the interviews indicates that women who have had miscarriages experience deep emotional responses and a long and difficult process of coming to terms with their loss. A contextual model of resilience provides a possible framework for understanding these apparently disparate results. Considering positive mental health as including the ability to deal constructively with negative life events, and consequent emotional distress, offers a model that distinguishes between poor mental health and the processes of coping with major life events. In the context of miscarriage, women's efforts to struggle with difficult emotions, and search for meaning, can be viewed as pathways to resilience rather than to psychological distress. Statement of contribution What is already known on this subject? Quantitative research shows that women who miscarry usually experience moderate depression and anxiety, which persists for around 6 months. Qualitative research shows that women who miscarry frequently experience deep grief, which can last for years. What does this study add? We consider ways in which these disparate findings might triangulate. The results suggest a need to distinguish between poor mental health and the experience of loss and grief. Adjusting to miscarriage is often emotionally challenging but not always associated with poor mental health. © 2014 The British Psychological Society.

Major depressive disorder (MDD) is one the most common mental disorders; it affects about 5-10% of the world population. This study explores the experiences of people with major depressive disorder in Zanjan, Iran. In order to identify recurring themes and patterns in individuals' experiences of major depressive disorder, semi-structured interviews with 18 patients were recorded and transcribed verbatim. The transcripts were then analyzed based on conventional qualitative content analysis. Five main categories emerged. The first category was called emotional paralysis and included the subcategories feeling severely depressed; feeling anxious; feeling impatient and irritable; and having dyshedonia. The second category was disturbance of thinking and was comprised of the subcategories of preoccupation, instable spiritual beliefs, and guilt. Cognitive decline was the third identified category and was further divided into subcategories of frustration, unawareness of the disorder, negative evaluation, indecisiveness, and loss of focus and loss of memory. Another major category was physical illnesses with the subcategories of physical discomfort, sleep problems, appetite disturbance, facial changes, sexual dysfunction, and medical conditions. The final category was failure in life, which had failure in personal affairs, jeopardized interpersonal relations, and unstable work life as subcategories. These findings provide a base for further research in this area. They also have clinical relevance for health care providers working with patients with MDD. Related cultural issues also are discussed.

From F = ma to Flying Squirrels: Curricular Change in an Introductory Physics Course

2013-01-01

We present outcomes from curricular changes made to an introductory calculus-based physics course whose audience is primarily life sciences majors, the majority of whom plan to pursue postbaccalaureate studies in medical and scientific fields. During the 2011–2012 academic year, we implemented a Physics of the Life Sciences curriculum centered on a draft textbook that takes a novel approach to teaching physics to life sciences majors. In addition, substantial revisions were made to the homework and hands-on components of the course to emphasize the relationship between physics and the life sciences and to help the students learn to apply physical intuition to life sciences–oriented problems. Student learning and attitudinal outcomes were assessed both quantitatively, using standard physics education research instruments, and qualitatively, using student surveys and a series of postsemester interviews. Students experienced high conceptual learning gains, comparable to other active learning–based physics courses. Qualitatively, a substantial fraction of interviewed students reported an increased interest in physics relative to the beginning of the semester. Furthermore, more than half of students self-reported that they could now relate physics topics to their majors and future careers, with interviewed subjects demonstrating a high level of ability to come up with examples of how physics affects living organisms and how it helped them to better understand content presented in courses in their major.

Theory and interpretation in qualitative studies from general practice: Why and how?

PubMed

Malterud, Kirsti

2016-03-01

In this article, I want to promote theoretical awareness and commitment among qualitative researchers in general practice and suggest adequate and feasible theoretical approaches. I discuss different theoretical aspects of qualitative research and present the basic foundations of the interpretative paradigm. Associations between paradigms, philosophies, methodologies and methods are examined and different strategies for theoretical commitment presented. Finally, I discuss the impact of theory for interpretation and the development of general practice knowledge. A scientific theory is a consistent and soundly based set of assumptions about a specific aspect of the world, predicting or explaining a phenomenon. Qualitative research is situated in an interpretative paradigm where notions about particular human experiences in context are recognized from different subject positions. Basic theoretical features from the philosophy of science explain why and how this is different from positivism. Reflexivity, including theoretical awareness and consistency, demonstrates interpretative assumptions, accounting for situated knowledge. Different types of theoretical commitment in qualitative analysis are presented, emphasizing substantive theories to sharpen the interpretative focus. Such approaches are clearly within reach for a general practice researcher contributing to clinical practice by doing more than summarizing what the participants talked about, without trying to become a philosopher. Qualitative studies from general practice deserve stronger theoretical awareness and commitment than what is currently established. Persistent attention to and respect for the distinctive domain of knowledge and practice where the research deliveries are targeted is necessary to choose adequate theoretical endeavours. © 2015 the Nordic Societies of Public Health.

Seasonal changes and effect of harvest on glucosinolates in Isatis leaves.

2008-04-01

The seasonal fluctuation of glucosinolates in five defined Isatis tinctoria and one Isatis indigotica accessions (first year, rosette stage), grown on field plots under identical conditions, was investigated. Analysis of the intact glucosinolates was carried out with shock frozen, freeze dried leaf samples using a recently developed and validated PLE (pressurized liquid extraction) protocol and ion-pair HPLC coupled with ESI-MS in the negative mode. When comparing the two Isatis species, significant qualitative and quantitative differences in the glucosinolate patterns were observed. Differences among the various Isatis tinctoria accessions were much smaller. We studied the effects of repeated harvesting during the growth season on glucosinolate concentrations and found that repeated harvest did not have a major effect on glucosinolate concentrations of newly grown leaves. Glucosinolates could not be detected in woad leaves submitted to conventional drying.

Perceptions of Successful Aging: Intergenerational Voices Value Well-Being.

Kelly, Gina Aalgaard; Lazarus, Jennie

2015-03-01

This study explored the perceptions of successful aging from intergenerational perspectives. A total of 66 participants were interviewed from three different generations including college students, parents, and grandparents. After qualitative data collection and analyses were used, five conceptual categories emerged from the data that related to perceptions of successful aging. The five concepts include wisdom, health, financial stability, staying active, and well-being. Conceptual categories emerged from the participants of different generations, and some were interconnected across generations. Each category is representative of major thematic patterns. Well-being was the primary concept which emerged because all three generations perceived and explicitly discussed well-being as the most valued aspect of successful aging. Previous successful aging research informed the use of a bio-psycho-social theoretical lens to frame the study findings and discussion. © The Author(s) 2015.

The role of observer bias in the North American Breeding Bird Survey

USGS Publications Warehouse

Faanes, C.A.; Bystrak, D.

1981-01-01

Ornithologists sampling breeding bird populations are subject to a number of biases in bird recognition and identification. Using Breeding Bird Survey data, these biases are examined qualitatively and quantitatively, and their effects on counts are evaluated. Differences in hearing ability and degree of expertise are the major observer biases considered. Other, more subtle influences are also discussed, including unfamiliar species, resolution, imagination, similar songs and attitude and condition of observers. In most cases, welltrained observers are comparable in ability and their differences contribute little beyond sampling error. However, just as hearing loss can affect results, so can an unprepared observer. These biases are important because they can reduce the credibility of any bird population sampling effort. Care is advised in choosing observers and in interpreting and using results when observers of variable competence are involved.

Introduction Women’s racial/ethnic-specific attitudes toward physical activity have been pointed out as a plausible reason for their low participation rates in physical activity. However, very little is actually known about racial/ethnic commonalties and differences in midlife women’s attitudes toward physical activity. The purpose of this study was to explore commonalities and differences in midlife women’s attitudes toward physical activity among four major racial/ethnic groups in the United States (whites, Hispanics, African Americans, and Asians). Methods This was a secondary analysis of the qualitative data from a larger study that explored midlife women’s attitudes toward physical activity. Qualitative data from four racial/ethnic-specific online forums among 90 midlife women were used for this study. The data were analyzed using thematic analysis, and themes reflecting commonalties and differences in the women’s attitudes toward physical activity across the racial/ethnic groups were extracted. Results The themes reflecting the commonalities were: (a) “physical activity is good for health”; (b) “not as active as I could be”; (c) “physical activity was not encouraged”; (d) “inherited diseases motivated participation in physical activity”; and (e) “lack of accessibility to physical activity.” The themes reflecting the differences were: (a) “physical activity as necessity or luxury”; (b) “organized versus natural physical activity”; (c) “individual versus family-oriented physical activity”; and (d) “beauty ideal or culturally accepted physical appearance.” Discussion Developing an intervention that could change the social influences and environmental factors and that could incorporate the women’s racial/ethnic-specific attitudes would be a priority in increasing physical activity of racial/ethnic minority midlife women.

QATT, a natural language interface developed for the Qualitative Process Engine (QPE) system is presented. The major goal was to evaluate the use of a preexisting natural language understanding system designed to be tailored for query processing in multiple domains of application. The other goal of QATT is to provide a comfortable environment in which to query envisionments in order to gain insight into the qualitative behavior of physical systems. It is shown that the use of the preexisting system made possible the development of a reasonably useful interface in a few months.

Moore, Rod; Brødsgaard, Inger; Rosenberg, Nicole

2004-04-19

Embarrassment is emphasized, yet scantily described as a factor in extreme dental anxiety or phobia. Present study aimed to describe details of social aspects of anxiety in dental situations, especially focusing on embarrassment phenomena. Subjects (Ss) were consecutive specialist clinic patients, 16 men, 14 women, 20-65 yr, who avoided treatment mean 12.7 yr due to anxiety. Electronic patient records and transcribed initial assessment and exit interviews were analyzed using QSR"N4" software to aid in exploring contexts related to social aspects of dental anxiety and embarrassment phenomena. Qualitative findings were co-validated with tests of association between embarrassment intensity ratings, years of treatment avoidance, and mouth-hiding behavioral ratings. Embarrassment was a complaint in all but three cases. Chief complaints in the sample: 30% had fear of pain; 47% cited powerlessness in relation to dental social situations, some specific to embarrassment and 23% named co-morbid psychosocial dysfunction due to effects of sexual abuse, general anxiety, gagging, fainting or panic attacks. Intense embarrassment was manifested in both clinical and non-clinical situations due to poor dental status or perceived neglect, often (n = 9) with fear of negative social evaluation as chief complaint. These nine cases were qualitatively different from other cases with chief complaints of social powerlessness associated with conditioned distrust of dentists and their negative behaviors. The majority of embarrassed Ss to some degree inhibited smiling/laughing by hiding with lips, hands or changed head position. Secrecy, taboo-thinking, and mouth-hiding were associated with intense embarrassment. Especially after many years of avoidance, embarrassment phenomena lead to feelings of self-punishment, poor self-image/esteem and in some cases personality changes in a vicious circle of anxiety and avoidance. Embarrassment intensity ratings were positively correlated with years of avoidance and degree of mouth-hiding behaviors. Embarrassment is a complex dental anxiety manifestation with qualitative differences by complaint characteristics and perceived intensity. Some cases exhibited manifestations similar to psychiatric criteria for social anxiety disorder as chief complaint, while most manifested embarrassment as a side effect.

The use of patient reported outcome measures (PROMs) in trauma is limited. The aim of this pilot study is to evaluate qualitative responses and factors affecting planned return to work following significant trauma, for which there is currently a poor evidence base. National ethical approval was obtained for routine prospective PROMs data collection, including EQ-5D, between Sept 2013 and March 2015 for trauma patients admitted to the Sussex Major Trauma Centre (n=92). 84 trauma patients disclosed their intended return to work at discharge. Additional open questions asked 'things done well' and 'things to be improved'. EQ-5D responses were valued using the time trade-off method. Statistical analysis between multiple variables was completed by ANOVA, and with categorical categories by Chi squared analysis. Only 18/68 of patients working at admission anticipated returning to work within 14days post-discharge. The injury severity scores (ISS) of those predicting return to work within two weeks and those predicting return to work longer than two weeks were 14.17 and 13.59, respectively. Increased physicality of work showed a trend towards poorer return to work outcomes, although non-significant in Chi-squared test in groups predicting return in less than or greater than two weeks (4.621, p=0.2017ns). No significant difference was demonstrated in the comparative incomes of patients with different estimated return to work outcomes (ANOVA r 2 =0.001, P=0.9590ns). EQ-5D scores were higher in those predicting return to work within two weeks when compared to greater than two weeks. Qualitative thematic content analysis of open responses was possible for 66/92 of respondents. Prominent positive themes were: care, staff, professionalism, and communication. Prominent negative themes were: food, ward response time, and communication. This pilot study highlights the importance of qualitative PROMs analysis in leading patient-driven improvements in trauma care. We provide standard deviations for ISS scores and EQ-5D scores in our general trauma cohort, for use in sample size calculations for further studies analysing factors affecting return to work after trauma.

Purpose: Medical and business are one of the most popular majors among students, and both fields require intensive training to reach certain level of expertise. During the development of professionalism, goal can become a crucial role in psychological impetus. The purpose of this study is to compare goal contents, goal characteristics, and effect of goal characteristics on student’s major satisfaction between medical and business. Methods: A total of 193 undergraduate students (97 medical students, 96 business students) answered survey questions including goal contents, goal characteristics (goal autonomy, goal attainability, social value of goal) and satisfaction on their majors. Qualitative analysis of goal contents and quantitative analysis of goal characteristics, and their effects on student major satisfaction were performed. Results: Goal content analysis showed percentage of social concern goal was higher in medical students (25.8%) than business students (6.3%), whereas percentage of wealth goal was higher business students (24.0%) than medical students (3.1%). Among goal characteristics, goal attainability and social value of goal were higher in medical students than business students. In both groups, social value of goal was significantly predict major satisfaction. Conclusion: Goal contents and goal characteristics are different between medical and business students. Curriculum and educational interventions that concerning students’ goal and developing programs to enhance students’ social value of goal is necessary. PMID:26838564

To understand the stigma perspective of siblings of children with major burn injury. A mixed method, qualitative-dominant study was conducted. The life story method was used for the qualitative portion. Only narratives from those family members describing the sibling's appearance change were used (N = 18 participants). Stigma experienced by siblings was first described by parents or noninjured siblings; they described how the sibling with changed appearance was stared at, ridiculed, or teased when they entered a new social situation. Only when specifically asked did the children with burn injury talk about their problems, saying, "This always happens when I go somewhere new." Children with changed appearance focused on normalizing their lives in a positive way. Oftentimes, it was a parent or noninjured sibling who would describe manifestations of stigma and ways they tried to protect the child with burn injury. ©2013 The Author(s) ©2013 American Association of Nurse Practitioners.

This article presents the state of the art of qualitative analysis in the framework of the chromatographic analysis. After establishing the differences between two main classes of qualitative analysis (analyte identification and sample classification/qualification) the particularities of instrumental qualitative analysis are commented on. Qualitative chromatographic analysis for sample classification/qualification through the so-called chromatographic fingerprint (for complex samples) or the volatiles profile (through the direct coupling headspace-mass spectrometry using the chromatograph as interface) is discussed. Next, more technical exposition of the qualitative chromatographic information is presented supported by a variety of representative examples.

Qualitative Secondary Analysis: A Case Exemplar.

Tate, Judith Ann; Happ, Mary Beth

Qualitative secondary analysis (QSA) is the use of qualitative data that was collected by someone else or was collected to answer a different research question. Secondary analysis of qualitative data provides an opportunity to maximize data utility, particularly with difficult-to-reach patient populations. However, qualitative secondary analysis methods require careful consideration and explicit description to best understand, contextualize, and evaluate the research results. In this article, we describe methodologic considerations using a case exemplar to illustrate challenges specific to qualitative secondary analysis and strategies to overcome them.

High school and college introductory science education experiences: A study regarding perceptions of university students persisting in science as a major area of study

NASA Astrophysics Data System (ADS)

Fredrick, L. Denise

The focus of this study was to investigate college students' perception of high school and college introductory science learning experiences related to persistence in science as a major area of study in college. The study included students' perceptions of the following areas of science education: (1) teacher interpersonal relationship with students, (2) teacher personality styles, (3) teacher knowledge of the content, (4) instructional methods, and (5) science course content. A survey research design was employed in the investigative study to collect and analyze data. One hundred ninety two students participated in the research study. A survey instrument entitled Science Education Perception Survey was used to collect data. The researcher sought to reject or support three null hypotheses as related to participants' perceptions of high school and college introductory science education experiences. Using binomial regression analysis, this study analyzed differences between students persisting in science and students not persisting in science as a major. The quantitative research indicated that significant differences exist between persistence in science as a major and high school science teacher traits and college introductory science instructional methods. Although these variables were found to be significant predictors, the percent variance was low and should be considered closely before concluded these as strong predictors of persistence. Major findings of the qualitative component indicated that students perceived that: (a) interest in high school science course content and high school science teacher personality and interpersonal relationships had the greatest effect on students' choice of major area of study; (b) interest in college introductory science course content had the greatest effect on students' choice of major area of study; (c) students recalled laboratory activities and overall good teaching as most meaningful to their high school science educational experiences and (d) students recalled laboratory activities and lectures linking practical application of science knowledge as meaningful to their college introductory science education experiences.

The meaning of body image experiences during the perinatal period: A systematic review of the qualitative literature.

2015-06-01

Literature reporting body image disturbances across the perinatal period has produced inconsistent findings, owing to the complexity of body image experiences during pregnancy and the first year postpartum. Existing qualitative data might provide potential avenues to advance understanding of pregnancy-related body image experiences and guide future quantitative research. The present systematic review synthesised the findings of 10 qualitative studies exploring the body image experiences of women through the perinatal period, albeit the majority focused only on pregnancy. Themes emerging included malleability of body image ideals across pregnancy (including the shift from aesthetic to functional concerns about one's appearance), the salience of stomach and breasts for self-rated body satisfaction, and perceived pressure to limit weight gain across pregnancy in order to return quickly to pre-pregnancy figure following birth. These qualitative findings suggest greater complexity of body image experiences during perinatal period than can be captured by typically used self-report measures. Crown Copyright © 2015.

Reported credibility techniques in higher education evaluation studies that use qualitative methods: A research synthesis.

PubMed

Liao, Hongjing; Hitchcock, John

2018-06-01

This synthesis study examined the reported use of credibility techniques in higher education evaluation articles that use qualitative methods. The sample included 118 articles published in six leading higher education evaluation journals from 2003 to 2012. Mixed methods approaches were used to identify key credibility techniques reported across the articles, document the frequency of these techniques, and describe their use and properties. Two broad sets of techniques were of interest: primary design techniques (i.e., basic), such as sampling/participant recruitment strategies, data collection methods, analytic details, and additional qualitative credibility techniques (e.g., member checking, negative case analyses, peer debriefing). The majority of evaluation articles reported use of primary techniques although there was wide variation in the amount of supporting detail; most of the articles did not describe the use of additional credibility techniques. This suggests that editors of evaluation journals should encourage the reporting of qualitative design details and authors should develop strategies yielding fuller methodological description.

Background: Student-teacher relationship is a salient issue in nursing education and has long-lasting implication in professional development of nursing students. Nowadays, this relationship in clinical settings is different from the past due to changing in nursing education paradigm. The purpose of this qualitative study was to explore the experiences of students and teachers about student-teacher relationship in the context of clinical nursing education in Iran. Materials and Methods: In this qualitative study that has been carried out adopting conventional qualitative content analysis approach, six bachelor nursing students and six clinical teachers in school of Nursing and Midwifery, were selected through purposive sampling. Semi-structured interview and participant observation were used for data collection. Interviews transcribed verbatim and analyzed using conventional content analysis through the process of data reduction and condensation, coding and also generating the categories and themes. Results: Results of the study showed the existence of a type of relationship in clinical education in which supportive actions of clinical teachers were prominent. These supportive actions appeared as three major categories including educational support, emotional support and social support which emerged from data. Conclusion: The results of this study explicit the ways that support could be provided for students in their relationship with clinical teachers. It also determines the teachers’ need to know more about the influence of their supportive relationship on students’ learning and the best possible outcomes of their education in clinical settings.

The delivery of bad news by oncologists to their patients is a key moment in the physician-patient relationship. We performed a systematic review of qualitative studies (a metasynthesis) that focused on the experiences and points of view of oncologists about breaking bad news to patients. We searched international publications to identify relevant qualitative research exploring oncologists' perspectives about this topic. Thematic analysis, which compensates for the potential lack of generalizability of the primary studies by their conjoint interpretation, was used to identify key themes and synthesize them. NVivo qualitative analysis software was used. We identified 40 articles (> 600 oncologists) from 12 countries and assessed their quality as good according to the Critical Appraisal Skills Programme (CASP). Two main themes emerged: the patient-oncologist encounter during the breaking of bad news, comprising essential aspects of the communication, including the process of dealing with emotions; and external factors shaping the patient-oncologist encounter, composed of factors that influence the announcement beyond the physician-patient relationship: the family, systemic and institutional factors, and cultural factors. Breaking bad news is a balancing act that requires oncologists to adapt continually to different factors: their individual relationships with the patient, the patient's family, the institutional and systemic environment, and the cultural milieu. Extending the development of the ability to personalize and adapt therapeutic treatment to this realm of communications would be a major step forward from the stereotyped way that oncologists are currently trained in communication skills. © 2015 by American Society of Clinical Oncology.

We study evoked calcium dynamics in astrocytes, a major cell type in the mammalian brain. Experimental evidence has shown that such dynamics are highly variable between different trials, cells, and cell subcompartments. Here we present a qualitative analysis of a recent mathematical model of astrocyte calcium responses. We show how the major response types are generated in the model as a result of the underlying bifurcation structure. By varying key channel parameters, mimicking blockers used by experimentalists, we manipulate this underlying bifurcation structure and predict how the distributions of responses can change. We find that store-operated calcium channels, plasma membrane bound channels with little activity during calcium transients, have a surprisingly strong effect, underscoring the importance of considering these channels in both experiments and mathematical settings. Variation in the maximum flow in different calcium channels is also shown to determine the range of stable oscillations, as well as set the range of frequencies of the oscillations. Further, by conducting a randomized search through the parameter space and recording the resulting calcium responses, we create a database that can be used by experimentalists to help estimate the underlying channel distribution of their cells.

Scaling of Device Variability and Subthreshold Swing in Ballistic Carbon Nanotube Transistors

Cao, Qing; Tersoff, Jerry; Han, Shu-Jen; Penumatcha, Ashish V.

2015-08-01

In field-effect transistors, the inherent randomness of dopants and other charges is a major cause of device-to-device variability. For a quasi-one-dimensional device such as carbon nanotube transistors, even a single charge can drastically change the performance, making this a critical issue for their adoption as a practical technology. Here we calculate the effect of the random charges at the gate-oxide surface in ballistic carbon nanotube transistors, finding good agreement with the variability statistics in recent experiments. A combination of experimental and simulation results further reveals that these random charges are also a major factor limiting the subthreshold swing for nanotube transistors fabricated on thin gate dielectrics. We then establish that the scaling of the nanotube device uniformity with the gate dielectric, fixed-charge density, and device dimension is qualitatively different from conventional silicon transistors, reflecting the very different device physics of a ballistic transistor with a quasi-one-dimensional channel. The combination of gate-oxide scaling and improved control of fixed-charge density should provide the uniformity needed for large-scale integration of such novel one-dimensional transistors even at extremely scaled device dimensions.

Orographic Flow over an Active Volcano

NASA Astrophysics Data System (ADS)

Poulidis, Alexandros-Panagiotis; Renfrew, Ian; Matthews, Adrian

2014-05-01

Orographic flows over and around an isolated volcano are studied through a series of numerical model experiments. The volcano top has a heated surface, so can be thought of as "active" but not erupting. A series of simulations with different atmospheric conditions and using both idealised and realistic configurations of the Weather Research and Forecast (WRF) model have been carried out. The study is based on the Soufriere Hills volcano, located on the island of Montserrat in the Caribbean. This is a dome-building volcano, leading to a sharp increase in the surface skin temperature at the top of the volcano - up to tens of degrees higher than ambient values. The majority of the simulations use an idealised topography, in order for the results to have general applicability to similar-sized volcanoes located in the tropics. The model is initialised with idealised atmospheric soundings, representative of qualitatively different atmospheric conditions from the rainy season in the tropics. The simulations reveal significant changes to the orographic flow response, depending upon the size of the temperature anomaly and the atmospheric conditions. The flow regime and characteristic features such as gravity waves, orographic clouds and orographic rainfall patterns can all be qualitatively changed by the surface heating anomaly. Orographic rainfall over the volcano can be significantly enhanced with increased temperature anomaly. The implications for the eruptive behaviour of the volcano and resulting secondary volcanic hazards will also be discussed.

Rehabilitation between institutional and non-institutional forensic psychiatric care: important influences on the transition process.

All patients cared for in forensic psychiatric care (FPC) have some kind of psychiatric disorder and most of them have committed one or more criminal acts. One part of the patient's rehabilitation is the transition from institutional to non-institutional FPC, but a number of patients do not succeed. The aim of this study was to elucidate different caregivers' experiences of aspects that influence the patients' ability to manage this rehabilitation. A qualitative approach was chosen. Data were collected by interviews in two focus groups, each group comprising of six caregivers representing both institutional and non-institutional FPC. The transcribed interviews were analysed using a qualitative content analysis. Important aspects influencing the patients' transition described were a well-planned care plan, together with a suitable non-institutional dwelling and a tailored occupation. Other important areas were having a well-functioning and trusting social network and a good relationship with a contact person/advocate. A major barrier to a successful transition was whether the patients managed their own finances or not. It was stated that it is important that the patients participate in the care and that different authorities create individual conditions and flexible solutions. All of these factors are important to focus on when caring for patients during their stay in the institutional FPC. © 2011 Blackwell Publishing.

Disease heterogeneity is a major issue in multiple sclerosis (MS). Classification of MS patients is usually based on clinical characteristics. More recently, a pathological classification has been presented. While clinical subtypes differ by magnetic resonance imaging (MRI) signature on a group level, a classification of individual MS patients based purely on MRI characteristics has not been presented so far. To investigate whether a restricted classification of MS patients can be made based on a combination of quantitative and qualitative MRI characteristics and to test whether the resulting subgroups are associated with clinical and laboratory characteristics. MRI examinations of the brain and spinal cord of 50 patients were scored for 21 quantitative and qualitative characteristics. Using latent class analysis, subgroups were identified, for whom disease characteristics and laboratory measures were compared. Latent class analysis revealed two subgroups that mainly differed in the extent of lesion confluency and MRI correlates of neuronal loss in the brain. Demographics and disease characteristics were comparable except for cognitive deficits. No correlations with laboratory measures were found. Latent class analysis offers a feasible approach for classifying subgroups of MS patients based on the presence of MRI characteristics. The reproducibility, longitudinal evolution and further clinical or prognostic relevance of the observed classification will have to be explored in a larger and independent sample of patients.

Qualitative approaches to use of the RE-AIM framework: rationale and methods.

PubMed

Holtrop, Jodi Summers; Rabin, Borsika A; Glasgow, Russell E

2018-03-13

There have been over 430 publications using the RE-AIM model for planning and evaluation of health programs and policies, as well as numerous applications of the model in grant proposals and national programs. Full use of the model includes use of qualitative methods to understand why and how results were obtained on different RE-AIM dimensions, however, recent reviews have revealed that qualitative methods have been used infrequently. Having quantitative and qualitative methods and results iteratively inform each other should enhance understanding and lessons learned. Because there have been few published examples of qualitative approaches and methods using RE-AIM for planning or assessment and no guidance on how qualitative approaches can inform these processes, we provide guidance on qualitative methods to address the RE-AIM model and its various dimensions. The intended audience is researchers interested in applying RE-AIM or similar implementation models, but the methods discussed should also be relevant to those in community or clinical settings. We present directions for, examples of, and guidance on how qualitative methods can be used to address each of the five RE-AIM dimensions. Formative qualitative methods can be helpful in planning interventions and designing for dissemination. Summative qualitative methods are useful when used in an iterative, mixed methods approach for understanding how and why different patterns of results occur. In summary, qualitative and mixed methods approaches to RE-AIM help understand complex situations and results, why and how outcomes were obtained, and contextual factors not easily assessed using quantitative measures.

The chemical composition and radical-scavenging activity of wood samples from 10 main Spanish olive cultivars were studied. The wood samples were collected during the pruning works from trees growing under the same agronomical and environmental conditions. The 10 ethyl acetate extracts were submitted to HPLC-DAD/ESI-MS analysis to determine the phenolic constituents. Seventeen compounds were identified (10 secoiridoids, 3 lignans, 2 phenol alcohols, 1 iridoid, and 1 flavonoid) by comparison with authentic samples. Significant quantitative and qualitative differences were found among olive cultivars. The lignan (+)-1-hydroxypinoresinol 1-O-β-d-glucopyranoside was the major compound in all olive cultivars, except in cultivars 'Farga' and 'Picual'. The multivariate analysis of all data revealed three sets of cultivars with similar compositions. Cultivars 'Gordal sevillana' and 'Picual' had the most distinct chemical profiles. With regard to the radical-scavenging activity, cultivar 'Picual', with oleuropein as the major phenolic, showed the highest activity (91.4 versus 18.6-32.7%).

The purpose of this study was to discover the care expressions, practices, and patterns of elderly Anglo- and African American elders. The domain of inquiry was the cultural care of elderly residents within the environmental context of a long-term care institution. The ethnonursing qualitative research method was used to conduct the study which was conceptualized within Leininger's theory of culture care diversity and universality. Four major themes were discovered: (a) Residents expressed and lived generic care to maintain their preadmission lifeways; (b) The nursing staff provided aspects of professional care to support satisfying lifeways for residents; (c) Institutional care patterns and expressions were viewed as a continuing life experience but with major differences between the apartment section and nursing home units; and (d) An institutional culture of the retirement home was discovered which reflected unique lifeways and shared care and health expressions and practices. These themes substantiated the culture care theory and revealed new modes of care for the elderly in an institutional setting.

Measuring post-secondary stem majors' engagement in sustainability: The creation, assessment, and validation of an instrument for sustainability curricula evaluation

NASA Astrophysics Data System (ADS)

Little, David L., II

Ongoing changes in values, pedagogy, and curriculum concerning sustainability education necessitate that strong curricular elements are identified in sustainability education. However, quantitative research in sustainability education is largely undeveloped or relies on outdated instruments. In part, this is because no widespread quantitative instrument for measuring related educational outcomes has been developed for the field, though their development is pivotal for future efforts in sustainability education related to STEM majors. This research study details the creation, evaluation, and validation of an instrument -- the STEM Sustainability Engagement Instrument (STEMSEI) -- designed to measure sustainability engagement in post-secondary STEM majors. The study was conducted in three phases, using qualitative methods in phase 1, a concurrent mixed methods design in phase 2, and a sequential mixed methods design in phase 3. The STEMSEI was able to successfully predict statistically significant differences in the sample (n= 1017) that were predicted by prior research in environmental education. The STEMSEI also revealed statistically significant differences between STEM majors' sustainability engagement with a large effect size (.203 ≤ eta2 ≤ .211). As hypothesized, statistically significant differences were found on the environmental scales across gender and present religion. With respect to gender, self-perceived measures of emotional engagement with environmental sustainability was higher with females while males had higher measures in cognitive engagement with respect to knowing information related to environmental sustainability. With respect to present religion, self-perceived measures of general engagement and emotional engagement in environmental sustainability were higher for non-Christians as compared to Christians. On the economic scales, statistically significant differences were found across gender. Specifically, measures of males' self-perceived cognitive engagement in knowing information related to economic sustainability were greater than those of females. Future research should establish the generalizability of these results and further test the validity of the STEMSEI.

"Phenomenology" and qualitative research methods.

PubMed

Nakayama, Y

1994-01-01

Phenomenology is generally based on phenomenological tradition from Husserl to Heidegger and Merleau-Ponty. As philosophical stances provide the assumptions in research methods, different philosophical stances produce different methods. However, the term "phenomenology" is used in various ways without the definition being given, such as phenomenological approach, phenomenological method, phenomenological research, etc. The term "phenomenology" is sometimes used as a paradigm and it is sometimes even viewed as synonymous with qualitative methods. As a result, the term "phenomenology" leads to conceptual confusions in qualitative research methods. The purpose of this paper is to examine the term "phenomenology" and explore philosophical assumptions, and discuss the relationship between philosophical stance and phenomenology as a qualitative research method in nursing.

Revisiting the Quantitative-Qualitative Debate: Implications for Mixed-Methods Research

Health care research includes many studies that combine quantitative and qualitative methods. In this paper, we revisit the quantitative-qualitative debate and review the arguments for and against using mixed-methods. In addition, we discuss the implications stemming from our view, that the paradigms upon which the methods are based have a different view of reality and therefore a different view of the phenomenon under study. Because the two paradigms do not study the same phenomena, quantitative and qualitative methods cannot be combined for cross-validation or triangulation purposes. However, they can be combined for complementary purposes. Future standards for mixed-methods research should clearly reflect this recommendation. PMID:26523073

Patient adherence to tuberculosis treatment: a systematic review of qualitative research.

Tuberculosis (TB) is a major contributor to the global burden of disease and has received considerable attention in recent years, particularly in low- and middle-income countries where it is closely associated with HIV/AIDS. Poor adherence to treatment is common despite various interventions aimed at improving treatment completion. Lack of a comprehensive and holistic understanding of barriers to and facilitators of, treatment adherence is currently a major obstacle to finding effective solutions. The aim of this systematic review of qualitative studies was to understand the factors considered important by patients, caregivers and health care providers in contributing to TB medication adherence. We searched 19 electronic databases (1966-February 2005) for qualitative studies on patients', caregivers', or health care providers' perceptions of adherence to preventive or curative TB treatment with the free text terms "Tuberculosis AND (adherence OR compliance OR concordance)". We supplemented our search with citation searches and by consulting experts. For included studies, study quality was assessed using a predetermined checklist and data were extracted independently onto a standard form. We then followed Noblit and Hare's method of meta-ethnography to synthesize the findings, using both reciprocal translation and line-of-argument synthesis. We screened 7,814 citations and selected 44 articles that met the prespecified inclusion criteria. The synthesis offers an overview of qualitative evidence derived from these multiple international studies. We identified eight major themes across the studies: organisation of treatment and care; interpretations of illness and wellness; the financial burden of treatment; knowledge, attitudes, and beliefs about treatment; law and immigration; personal characteristics and adherence behaviour; side effects; and family, community, and household support. Our interpretation of the themes across all studies produced a line-of-argument synthesis describing how four major factors interact to affect adherence to TB treatment: structural factors, including poverty and gender discrimination; the social context; health service factors; and personal factors. The findings of this study are limited by the quality and foci of the included studies. Adherence to the long course of TB treatment is a complex, dynamic phenomenon with a wide range of factors impacting on treatment-taking behaviour. Patients' adherence to their medication regimens was influenced by the interaction of a number of these factors. The findings of our review could help inform the development of patient-centred interventions and of interventions to address structural barriers to treatment adherence.

Sharing injection equipment remains an important rout of transmission of HIV and HCV infections in the region of Eastern Europe and Central Asia. Tajikistan is one of the most affected countries with high rates of injection drug use and related epidemics.The aim of this qualitative study was to describe drug use practices and related behaviors in two Tajik cities - Kulob and Khorog. Twelve focus group discussions (6 per city) with 100 people who inject drugs recruited through needle and syringe program (NSP) outreach in May 2014. Topics covered included specific drugs injected, drug prices and purity, access to sterile equipment, safe injection practices and types of syringes and needles used. Qualitative thematic analysis was performed using NVivo 10 software. All participants were male and ranged in age from 20 to 78 years. Thematic analysis showed that cheap Afghan heroin, often adulterated by dealers with other admixtures, was the only drug injected. Drug injectors often added Dimedrol (Diphenhydramine) to increase the potency of "low quality" heroin. NSPs were a major source of sterile equipment. Very few participants report direct sharing of needles and syringes. Conversely, many participants reported preparing drugs jointly and sharing injection paraphernalia. Using drugs in an outdoor setting and experiencing withdrawal were major contributors to sharing equipment, using non-sterile water, not boiling and not filtering the drug solution. Qualitative research can provide insights into risk behaviors that may be missed in quantitative studies. These finding have important implications for planning risk reduction interventions in Tajikistan. Prevention should specifically focus on indirect sharing practices.

Shields, Ryan Y

2016-01-01

Context Minimal research has examined the recent exportation of medical curricula to international settings. Johns Hopkins University School of Medicine in Baltimore, USA partnered with Perdana University Graduate School of Medicine in Kuala Lumpur, Malaysia and implemented the same curriculum currently used at Johns Hopkins University to teach medical students at Perdana University. This study aimed to explore the perspectives of first-year medical students at Perdana University, focusing on issues of cultural dissonance during adaptation to a US curriculum. Methods In-depth semi-structured interviews with the inaugural class of first-year students (n=24) were conducted, audio-recorded, and transcribed. Two reviewers independently coded and analyzed the qualitative data for major themes. Results The most prominent themes identified were the transition from a “passive” to an “active” learning environment and the friendliness and openness of the professors. Students noted that “[Perdana University] is a whole new, different culture and now we are adapting to the culture.” Being vocal during classes and taking exams based on conceptual understanding and knowledge application/integration proved to be more challenging for students than having classes taught entirely in English or the amount of material covered. Discussion This study reinforced many cultural education theories as it revealed the major issues of Malaysian graduate students adapting to a US-style medical curriculum. Despite coming from a collectivistic, Confucian-based cultural learning background, the Malaysian students at Perdana University adopted and adapted to, and subsequently supported, the US learning expectations.

Examining Medical Student Specialty Choice Through a Gender Lens: An Orientational Qualitative Study.

Smith, Victoria; Bethune, Cheri; Hurley, Katrina F

2018-01-01

Phenomenon: A growing number of women are entering the medical workforce, yet their distribution across medical specialties remains nonuniform. We sought to describe how culture, bias, and socialization shape gendered thinking regarding specialty choice at a Canadian undergraduate medical institution. We analyzed transcripts from the Career Choices Project: 16 semistructured focus group discussions with 70 students graduating from Memorial University of Newfoundland in 2003, 2006, 2007, and 2008. The questions and prompts were designed to explore factors influencing specialty choice and did not specifically probe gender-based experiences. Focus groups were audio-recorded, transcribed, and deidentified before analysis. Analysis was inductive and guided by principles of orientational qualitative inquiry using a gender-specific lens. The pursuits of personal and professional goals, as well as contextual factors, were the major themes that influenced decision-making for women and men. Composition of these major themes varied between genders. Influence of a partner, consideration of familial commitments (both present and future), feeling a sense of connectedness with the field in question, and social accountability were described by women as important. Both genders hoped to pursue careers that would afford "flexibility" in order to balance work with their personal lives, though the construct of work-life balance differed between genders. Women did not explicitly identify gender bias or sexism as influencing factors, but their narratives suggest that these elements were at play. Insights: Our findings suggest that unlike men, women's decision-making is informed by tension between personal and professional goals, likely related to the context of gendered personal and societal expectations.

The secondary metabolites in the roots, leaves and flowers of the common dandelion (Taraxacum officinale agg.) have been studied in detail. However, little is known about the specific constituents of the plant's highly specialized laticifer cells. Using a combination of liquid and gas chromatography, mass spectrometry and nuclear magnetic resonance spectrometry, we identified and quantified the major secondary metabolites in the latex of different organs across different growth stages in three genotypes, and tested the activity of the metabolites against the generalist root herbivore Diabrotica balteata. We found that common dandelion latex is dominated by three classes of secondary metabolites: phenolic inositol esters (PIEs), triterpene acetates (TritAc) and the sesquiterpene lactone taraxinic acid β-D-glucopyranosyl ester (TA-G). Purification and absolute quantification revealed concentrations in the upper mgg(-1) range for all compound classes with up to 6% PIEs, 5% TritAc and 7% TA-G per gram latex fresh weight. Contrary to typical secondary metabolite patterns, concentrations of all three classes increased with plant age. The highest concentrations were measured in the main root. PIE profiles differed both quantitatively and qualitatively between plant genotypes, whereas TritAc and TA-G differed only quantitatively. Metabolite concentrations were positively correlated within and between the different compound classes, indicating tight biosynthetic co-regulation. Latex metabolite extracts strongly repelled D. balteata larvae, suggesting that the latex constituents are biologically active. Copyright © 2015 Elsevier Ltd. All rights reserved.

To investigate reasons behind strong opposition to water fluoridation in regional New South Wales, Australia, and to make recommendations to improve community engagement. Few studies have used qualitative methodologies to understand the reasons for strong antifluoridation views. An understanding of these reasons could be useful when designing public campaigns to combat the strong antifluoridation message. The qualitative study used semistructured interviewing and thematic analysis. Ten participants were recruited using purposive and snowball sampling methods until data saturation was reached. Thematic analysis and graphical representation of themes assisted in analysing the data for logical connections and relationships. Six dominant themes and numerous subthemes were identified. Five of the major themes were reasons for opposition: scepticism, health effects, ethics, environmental impacts and economics. Each of these was inextricably linked to a sixth major theme: alternatives to fluoridation. All participants had strongly held antifluoridation views, and provided a unique insight into their perceptions and reasons for opposing water fluoridation. Concerns about 'fraudulent research' and the influence of industry on government bodies were novel themes. The concerns raised could be used to inform future population health campaigns, research, public education and resource-allocation decisions. Open community consultation may be able to address the issues raised in a nonjudgemental and collaborative manner.

Climate change and vulnerability are major challenges in ensuring household food security. Climate information services have the potential to cushion rural households from extreme climate risks. However, most the probabilistic nature of climate information products is not easily understood by majority of smallholder farmers. Despite the probabilistic nature, climate information have proved to be a valuable climate risk adaptation strategy at the farm level. This calls for innovative ways to help farmers understand and apply climate information services to inform their farm level decisions. The study endeavored to co-design and test appropriate innovation systems for climate information services uptake and scale up necessary for achieving climate risk development. In addition it also determined the conditions necessary to support the effective performance of the proposed innovation system. Data and information sources included systematic literature review, secondary sources, government statistics, focused group discussions, household surveys and semi-structured interviews. Data wasanalyzed using both quantitative and qualitative data analysis techniques. Quantitative data was analyzed using the Statistical Package for Social Sciences (SPSS) software. Qualitative data was analyzed using qualitative techniques, which involved establishing the categories and themes, relationships/patterns and conclusions in line with the study objectives. Sustainable livelihood, reduced household poverty and climate change resilience were the impact that resulted from the study.

Rapid, clear and efficient communication of neuropsychological results is essential to benefit patient care. Errors in communication are a lead cause of medical errors; nevertheless, there remains a lack of consistency in how neuropsychological scores are communicated. A major limitation in the communication of neuropsychological results is the inconsistent use of qualitative descriptors for standardized test scores and the use of vague terminology. PubMed search from 1 Jan 2007 to 1 Aug 2016 to identify guidelines or consensus statements for the description and reporting of qualitative terms to communicate neuropsychological test scores was conducted. The review found the use of confusing and overlapping terms to describe various ranges of percentile standardized test scores. In response, we propose a simplified set of qualitative descriptors for normalized test scores (Q-Simple) as a means to reduce errors in communicating test results. The Q-Simple qualitative terms are: 'very superior', 'superior', 'high average', 'average', 'low average', 'borderline' and 'abnormal/impaired'. A case example illustrates the proposed Q-Simple qualitative classification system to communicate neuropsychological results for neurosurgical planning. The Q-Simple qualitative descriptor system is aimed as a means to improve and standardize communication of standardized neuropsychological test scores. Research are needed to further evaluate neuropsychological communication errors. Conveying the clinical implications of neuropsychological results in a manner that minimizes risk for communication errors is a quintessential component of evidence-based practice.

The reliability and validity of qualitative research findings are viewed with scepticism by some scientists. This scepticism is derived from the belief that qualitative researchers give insufficient attention to estimating reliability and validity of data, and the differences between quantitative and qualitative methods in assessing data. The danger of this scepticism is that relevant and applicable research findings will not be used. Our purpose is to describe an evaluative strategy for use with qualitative data, a strategy that is a synthesis of quantitative and qualitative assessment methods. Results of the strategy and factors that influence its use are also described.

A hot debate exists in our country as to the models of home care which must be developed. This study is aimed at ascertaining how the family caregivers of terminal cancer patients, of the elderly suffering from dementia and of individuals having undergone major operations in outpatient surgery programs rate the quality of the home care provided. A phenomenological type qualitative study based on discussion groups (9), triangular groups (5) and in-depth interviews (22). This study was conducted in Andalusia throughout the 1999-2000 period. The subjects of the study were the main caregivers of patients provided with home care through the healthcare centers. The information must be analyzed by means of a Nudist-4 software-aided content analysis. The analysis variables were those of the Servqual model. For the caregivers of cancer patients, the most important aspects of the quality of the home care provided were the Response Capacity and Accessibility. This analysis revealed that the patients suffered pain but the pain was not controlled. Negative aspects hindering accessibility were the lack of home care coverage outside of regular working hours, the difficulty of getting in touch by phone, the length of time it takes for someone to come and the visits solely on request. The caregivers of patients having undergone major outpatient surgery want Security and Reliability. They complain of the short length of time within which the patients are released from the hospital and of the home care provided by the health care center. The caregivers of the elderly with dementia place top priority on being provided with the materials they need to take care of these patients. Caregivers' and patients' expectations differ, depending on health problems, therefore, the type of home care provided should vary, according to the health problems involved. It is necessary to develop a flexible model, capable of adapting to different patient needs and the diverse circumstances that affect family caregivers.

Objective To explore existential meaning-making in an ethnic-majority subgroup with mental ill health and to increase knowledge about the importance of gaining access to such information in mental healthcare. Design Qualitative study using in-depth interviews and systematic text condensation analysis. Participants 17 devote Christians with an ethnic-Swedish background, 12 women and 5 men, 30–73 years old, from different congregations across Sweden, having sought medical care for mental ill health of any kind. Setting The secular Swedish society. Results A living, although asymmetric, relationship with God often was seen as the most important relationship, giving hope and support when ill, but creating feelings of abandonment and fear if perceived as threatened. Symptoms were interpreted through an existential framework influenced by their view of God. A perceived judging God increased feelings of guilt, sinfulness and shame. A perceived merciful God soothed symptoms and promoted recovery. Existential consequences, such as being unable to pray or participate in congregational rituals, caused feelings of ‘spiritual homelessness’. Participants gave biopsychosocial explanations of their mental ill health, consonant with and sometimes painfully conflicting with existential explanations, such as being attacked by demons. Three different patterns of interaction among biopsychosocial and existential dimensions in their explanatory systems of illness causation were identified: (a) comprehensive thinking and consensus; (b) division and parallel functions and (c) division and competitive functions. Conclusions Prevailing medical models for understanding mental ill health do not include the individual's existential experiences, which are important for identifying risk and protective factors as well as possible resources for recovery. The various expressions of existential meaning-making identified in this devout religious subgroup illustrate that existential information cannot be generalised, even within a small, seemingly homogenous group. The three identified patterns of interactions formed a typology that may be of use in clinical settings. PMID:27797991

Institutional review boards (IRBs) are responsible for weighing the risks and benefits of research participation. Qualitative researchers note numerous instances where IRB ethical frameworks fail to align with the ethics of their research projects and point out that IRB understandings of the benefits and risks of research often differ from those of the participants they seek to protect. This qualitative cross-case research investigates participants' interview experiences in six qualitative studies that differed in their methods, subject of focus, and populations. Our findings indicate that contemporary IRBs' use of population "vulnerability" and topic "sensitivity" to assess project risk does not adequately determine the benefits, risks, or ethicality of research. We recommend that IRBs treat as real the evidence for benefits in qualitative research, recognize that sensitivity and vulnerability do not predict risk, and encourage researchers to attend to relationships in their projects. © The Author(s) 2015.

Conducting qualitative research in mental health: Thematic and content analyses.

Crowe, Marie; Inder, Maree; Porter, Richard

2015-07-01

The objective of this paper is to describe two methods of qualitative analysis - thematic analysis and content analysis - and to examine their use in a mental health context. A description of the processes of thematic analysis and content analysis is provided. These processes are then illustrated by conducting two analyses of the same qualitative data. Transcripts of qualitative interviews are analysed using each method to illustrate these processes. The illustration of the processes highlights the different outcomes from the same set of data. Thematic and content analyses are qualitative methods that serve different research purposes. Thematic analysis provides an interpretation of participants' meanings, while content analysis is a direct representation of participants' responses. These methods provide two ways of understanding meanings and experiences and provide important knowledge in a mental health context. © The Royal Australian and New Zealand College of Psychiatrists 2015.

Power relations in qualitative research.

2009-02-01

This article focuses on the tensions between the commitment to power redistribution of the qualitative paradigm and the ethical and methodological complexity inherent in clinical research. Qualitative inquiry, in general, though there are significant variations between its different paradigms and traditions, proposes to reduce power differences and encourages disclosure and authenticity between researchers and participants. It clearly departs from the traditional conception of quantitative research, whereby the researcher is the ultimate source of authority and promotes the participants' equal participation in the research process. But it is precisely this admirable desire to democratize the research process, and the tendency to question traditional role boundaries, that raises multiple ethical dilemmas and serious methodological challenges. In this article, we offer a conceptual frame for addressing questions of power distribution in qualitative research through a developmental analysis of power relations across the different stages of the research process. We discuss ethical and methodological issues.

The Biological Big Bang model for the major transitions in evolution.

PubMed

Koonin, Eugene V

2007-08-20

Major transitions in biological evolution show the same pattern of sudden emergence of diverse forms at a new level of complexity. The relationships between major groups within an emergent new class of biological entities are hard to decipher and do not seem to fit the tree pattern that, following Darwin's original proposal, remains the dominant description of biological evolution. The cases in point include the origin of complex RNA molecules and protein folds; major groups of viruses; archaea and bacteria, and the principal lineages within each of these prokaryotic domains; eukaryotic supergroups; and animal phyla. In each of these pivotal nexuses in life's history, the principal "types" seem to appear rapidly and fully equipped with the signature features of the respective new level of biological organization. No intermediate "grades" or intermediate forms between different types are detectable. Usually, this pattern is attributed to cladogenesis compressed in time, combined with the inevitable erosion of the phylogenetic signal. I propose that most or all major evolutionary transitions that show the "explosive" pattern of emergence of new types of biological entities correspond to a boundary between two qualitatively distinct evolutionary phases. The first, inflationary phase is characterized by extremely rapid evolution driven by various processes of genetic information exchange, such as horizontal gene transfer, recombination, fusion, fission, and spread of mobile elements. These processes give rise to a vast diversity of forms from which the main classes of entities at the new level of complexity emerge independently, through a sampling process. In the second phase, evolution dramatically slows down, the respective process of genetic information exchange tapers off, and multiple lineages of the new type of entities emerge, each of them evolving in a tree-like fashion from that point on. This biphasic model of evolution incorporates the previously developed concepts of the emergence of protein folds by recombination of small structural units and origin of viruses and cells from a pre-cellular compartmentalized pool of recombining genetic elements. The model is extended to encompass other major transitions. It is proposed that bacterial and archaeal phyla emerged independently from two distinct populations of primordial cells that, originally, possessed leaky membranes, which made the cells prone to rampant gene exchange; and that the eukaryotic supergroups emerged through distinct, secondary endosymbiotic events (as opposed to the primary, mitochondrial endosymbiosis). This biphasic model of evolution is substantially analogous to the scenario of the origin of universes in the eternal inflation version of modern cosmology. Under this model, universes like ours emerge in the infinite multiverse when the eternal process of exponential expansion, known as inflation, ceases in a particular region as a result of false vacuum decay, a first order phase transition process. The result is the nucleation of a new universe, which is traditionally denoted Big Bang, although this scenario is radically different from the Big Bang of the traditional model of an expanding universe. Hence I denote the phase transitions at the end of each inflationary epoch in the history of life Biological Big Bangs (BBB). A Biological Big Bang (BBB) model is proposed for the major transitions in life's evolution. According to this model, each transition is a BBB such that new classes of biological entities emerge at the end of a rapid phase of evolution (inflation) that is characterized by extensive exchange of genetic information which takes distinct forms for different BBBs. The major types of new forms emerge independently, via a sampling process, from the pool of recombining entities of the preceding generation. This process is envisaged as being qualitatively different from tree-pattern cladogenesis.

2016-01-01

Global literature has suggested a negative impact of acculturative stress on both physical and mental health among international migrants. In China, approximately 20 percent of its population is rural-to-urban migrant workers and there are significant cultural differences between rural and urban societies, but no data are available regarding the acculturative stress of Chinese migrant workers. This study aimed to explore the forms and contexts of acculturative stress among Chinese migrant workers. Qualitative data were collected from four focus group discussions with 17 Chinese rural-to-urban migrant workers and three individual interviews with three medical professionals who provided mental health services for factory-workers in Shenzhen, China. The data in the current study showed that rural-to-urban migrant workers in China had experienced various forms of acculturative stress including difficulties in adapting to the environment, work-related stress, family-related stress, financial hardship, and lack of sense of belonging to cities. Rural-to-urban migration in China is a challenging transition with significant acculturative stress and demands for major adjustments among migrant workers. The assessment and management of acculturative stress is a necessary first step in providing mental health services to migrant workers.

What we talk about when we talk about recovery: a systematic review and best-fit framework synthesis of qualitative literature.

2017-06-01

The recovery approach is increasingly popular among mental-health services, but there is a lack of consensus about its applicability and it has been criticised for imposing professionalised ideas onto what was originally a service-user concept. To carry out a review and synthesis of qualitative research to answer the question: "What do we know about how service users with severe and enduring mental illness experience the process of recovery?" It was hoped that this would improve clarity and increase understanding. A systematic review identified 15 peer-reviewed articles examining experiences of recovery. Twelve of these were analysed using best-fit framework synthesis, with the CHIME model of recovery providing the exploratory framework. The optimistic themes of CHIME accounted for the majority of people's experiences, but more than 30% of data were not felt to be encapsulated. An expanded conceptualisation of recovery is proposed, in which difficulties are more prominently considered. An overly optimistic, professionally imposed view of recovery might homogenise or even blame individuals rather than empower them. Further understanding is needed of different experiences of recovery, and of people's struggles to recover.

2017-11-01

The aims of this study were to (1) describe the practices that school-based physical therapists use in developing student goals, and (2) identify facilitators and barriers to development of goals that are specific to participation in the context of the school setting. 46 school-based physical therapists who participated in a previous study on school-based physical therapy practice (PT COUNTS) completed a questionnaire on goal development. Frequencies and cross tabulations were generated for quantitative data. Open-ended questions were analyzed using an iterative qualitative analysis process. A majority of therapists reported that they frequently develop goals collaboratively with other educational team members. Input from teachers, related services personnel, and parents has the most influence on goal development. Qualitative analysis identified five themes that influence development of participation-based goals: (1) school-based philosophy and practice; (2) the educational environment, settings, and routines; (3) student strengths, needs, and personal characteristics; (4) support from and collaboration with members of the educational team; and (5) therapist practice and motivation. Goal development is a complex process that involves multiple members of the educational team and is influenced by many different aspects of practice, the school environment, and student characteristics.

Qualitative and quantitative composition of essential oils: A literature-based database on contact allergens used for safety assessment.

Dornic, N; Ficheux, A S; Roudot, A C

2016-10-01

The risks related to the use of essential oils are difficult to ascertain at present, due in part to the large number of different oils available on the market, making it difficult for the risk assessor. Essential oils may contain skin allergens in significant amounts, and could thus pose a risk to the consumer. The aim of our study was to collect as much qualitative and quantitative data as possible on allergens present in essential oils. 11 types of essential oils, with 25 respective subspecies, were taken into account based on a previous survey. Based on the literature, 517 dosages were recorded from 112 publications, providing precious information for probabilistic exposure assessment purposes. 22 substances recognized as established allergens were found in the essential oils we included. Of these, 11 are also found in cosmetics as fragrance components. These results are of major importance regarding co-exposure to fragrance allergens. Moreover, this could lead to regulatory measures for essential oils in the future, as it is the case for cosmetic products, in order to better protect consumers against skin allergy.

Engagement of nurses in their profession. Qualitative study on engagement.

PubMed

García-Sierra, Rosa; Fernández-Castro, Jordi; Martínez-Zaragoza, Fermín

To identify common issues of nurses with high engagement to enable us to develop the construct as it applies to nursing in more depth. Based on the constructivist paradigm and with a phenomenological approach, a qualitative content analysis was conducted using an inductive approach. Participants were nurses working in direct care in different healthcare areas. The sample size was determined by data saturation and 15 participants were interviewed. The units of meaning were grouped into 11 subcategories, and then into 7 categories termed vigour, dedication, reward, autonomy, social support, conciliation and attributes of nurses. Then these categories were grouped into 3 major themes: job characteristics, characteristics of organizations, and individual characteristics. Having high engagement does not mean ignoring the negative aspects of work and organizations. Nurses who maintain high engagement are also affected by the negative aspects, however the assessment of positive aspects such as enjoying the work, the meaning of being a nurse, reward and autonomy enable the process of depletion of engagement to be overcome. In view of the findings, we propose reconceptualising the construct, taking the features of nursing into account. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

Dying cancer patients' own opinions on euthanasia: an expression of autonomy? A qualitative study.

PubMed

Karlsson, Marit; Milberg, Anna; Strang, Peter

2012-01-01

Deliberations on euthanasia are mostly theoretical, and often lack first-hand perspectives of the affected persons. Sixty-six patients suffering from cancer in a palliative phase were interviewed about their perspectives of euthanasia in relation to autonomy. The interviews were transcribed verbatim and analysed using qualitative content analysis with no predetermined categories. The informants expressed different positions on euthanasia, ranging from support to opposition, but the majority were undecided due to the complexity of the problem. The informants' perspectives on euthanasia in relation to autonomy focused on decision making, being affected by (1) power and (2) trust. Legalization of euthanasia was perceived as either (a) increasing patient autonomy by patient empowerment, or (b) decreasing patient autonomy by increasing the medical power of the health care staff, which could be frightening. The informants experienced dependence on others, and expressed various levels of trust in others' intentions, ranging from full trust to complete mistrust. Dying cancer patients perceive that they cannot feel completely independent, which affects true autonomous decision making. Further, when considering legalization of euthanasia, the perspectives of patients fearing the effects of legalization should also be taken into account, not only those of patients opting for it.

Knowledge of the complete nucleotide sequence of the mouse TCRAD locus allows an accurate determination V-J rearrangement status. Using multiplex genomic PCR assays and real time PCR analysis, we report a comprehensive and systematic analysis of the V-J recombination of TCR α chain in normal mouse thymocytes during development. These respective qualitative and quantitative approaches give rise to four major points describing the control of gene rearrangements. (a) The V-J recombination pattern is not random during ontogeny and generates a limited TCR α repertoire; (b) V-J rearrangement control is intrinsic to the thymus; (c) each V gene rearranges to a set of contiguous J segments with a gaussian-like frequency; (d) there are more rearrangements involving V genes at the 3′ side than 5′ end of V region. Taken together, this reflects a preferential association of V and J gene segments according to their respective positions in the locus, indicating that accessibility of both V and J regions is coordinately regulated, but in different ways. These results provide a new insight into TCR α repertoire size and suggest a scenario for V usage during differentiation. PMID:12417627

A new qualitative acoustic emission parameter based on Shannon's entropy for damage monitoring

NASA Astrophysics Data System (ADS)

Chai, Mengyu; Zhang, Zaoxiao; Duan, Quan

2018-02-01

An important objective of acoustic emission (AE) non-destructive monitoring is to accurately identify approaching critical damage and to avoid premature failure by means of the evolutions of AE parameters. One major drawback of most parameters such as count and rise time is that they are strongly dependent on the threshold and other settings employed in AE data acquisition system. This may hinder the correct reflection of original waveform generated from AE sources and consequently bring difficulty for the accurate identification of the critical damage and early failure. In this investigation, a new qualitative AE parameter based on Shannon's entropy, i.e. AE entropy is proposed for damage monitoring. Since it derives from the uncertainty of amplitude distribution of each AE waveform, it is independent of the threshold and other time-driven parameters and can characterize the original micro-structural deformations. Fatigue crack growth test on CrMoV steel and three point bending test on a ductile material are conducted to validate the feasibility and effectiveness of the proposed parameter. The results show that the new parameter, compared to AE amplitude, is more effective in discriminating the different damage stages and identifying the critical damage.

To provide an in-depth account of the experience of pre-implantation genetic diagnosis (PGD). Exploratory qualitative interview study. Participants were recruited from one major in vitro fertilization (IVF) clinic in Sydney, Australia. Data were collected through 14 in-depth interviews with women at different stages of PGD, utilized a thematic approach and facilitated by NVivo software. Women reported using PGD as empowering and led them to feel in control of their reproductive futures. Health professionals who did not tell women about PGD were seen as a barrier to accessing treatment. The ability to select embryos free from the genetic condition (for which it was at risk) alleviated stress. Despite this, stress experienced with PGD was significant for women, and often related to past experiences of reproductive trauma and grief. The outcome of embryos was also the cause of stress for women. Women undergoing PGD have a diverse range of reproductive and genetic histories, psychosocial circumstances and world views that all interact and impact their experience of PGD. Successful support and care of these women should address all of these factors and tailor the support provided for women using this physically and emotionally complex form of reproductive technology.

Fingerprints of carbon, nitrogen, and silicon isotopes in small interstellar SiC grains from the Murchison meteorite

We report ion microprobe determinations of the carbon, nitrogen, and silicon isotopic compositions of small SiC grains from the Murchison CM2 chondrite. Analyses were made on samples containing variable numbers of grains and on 14 individual grains. In some cases the multiple-grain sample compositions were probably dominated by only one or two grains. Total ranges observed are given. Only a few grains show values near the range limits. Both the total ranges of carbon and nitrogen isotopic compositions, and even the narrower ranges typical for the majority of the grains, are similar to those observed for larger SiC grains. Two rare components appear to be present in the smaller-size fraction, one characterized by C-12/C-13 about 12-16 and the other by very heavy nitrogen. The carbon and nitrogen isotopic compositions qualitatively may reflect hydrostatic H-burning via the CNO cycle and He-burning in red giants, as well as explosive H-burning in novae. The silicon isotopic compositions of most grains qualitatively show what is the signature of He-burning. The silicon isotopic composition of one grain, however, suggests a different process.

To describe the experiences and perspectives of children and adolescents on dialysis. A systematic review of qualitative studies was conducted that explored the experiences of children on dialysis. Electronic databases and reference lists of relevant articles were searched to October Week 2, 2010. A total of 17 studies, which reported the experiences of 143 children receiving dialysis, were included. Five major themes were identified: loss of control (high reliance on carers, parental overprotectiveness, unrelenting dependence on a machine, impaired body integrity), restricted lifestyle (limited socialisation opportunities, academic struggle), coping strategies (hope for kidney transplant and medical advances, social support, positive determination and self-awareness, engaging in activities, denial), managing treatment (ownership, proactive involvement, adherence to fluid and diet restrictions) and feeling different (abnormal physical appearance, injustice, being a burden). Children undergoing dialysis experience impaired growth, invasive procedures, school and social constraints. They often have poor self-esteem and a pervasive sense of losing their identity, body integrity, control, independence and opportunity. Interventions are needed to equip children with the capacity to manage their health, participate in community, engage in 'permissible' recreational activities, progress in their studies, and remain vigilant in dialysis and treatment responsibilities, for improved health and treatment outcomes.

Revision of the Malagasy Camponotus edmondi species group (Hymenoptera, Formicidae, Formicinae): integrating qualitative morphology and multivariate morphometric analysis.

Rakotonirina, Jean Claude; Csősz, Sándor; Fisher, Brian L

2016-01-01

The Malagasy Camponotus edmondi species group is revised based on both qualitative morphological traits and multivariate analysis of continuous morphometric data. To minimize the effect of the scaling properties of diverse traits due to worker caste polymorphism, and to achieve the desired near-linearity of data, morphometric analyses were done only on minor workers. The majority of traits exhibit broken scaling on head size, dividing Camponotus workers into two discrete subcastes, minors and majors. This broken scaling prevents the application of algorithms that uses linear combination of data to the entire dataset, hence only minor workers were analyzed statistically. The elimination of major workers resulted in linearity and the data meet required assumptions. However, morphometric ratios for the subsets of minor and major workers were used in species descriptions and redefinitions. Prior species hypotheses and the goodness of clusters were tested on raw data by confirmatory linear discriminant analysis. Due to the small sample size available for some species, a factor known to reduce statistical reliability, hypotheses generated by exploratory analyses were tested with extreme care and species delimitations were inferred via the combined evidence of both qualitative (morphology and biology) and quantitative data. Altogether, fifteen species are recognized, of which 11 are new to science: Camponotus alamaina sp. n. , Camponotus androy sp. n. , Camponotus bevohitra sp. n. , Camponotus galoko sp. n. , Camponotus matsilo sp. n. , Camponotus mifaka sp. n. , Camponotus orombe sp. n. , Camponotus tafo sp. n. , Camponotus tratra sp. n. , Camponotus varatra sp. n. , and Camponotus zavo sp. n. Four species are redescribed: Camponotus echinoploides Forel, Camponotus edmondi André, Camponotus ethicus Forel, and Camponotus robustus Roger. Camponotus edmondi ernesti Forel, syn. n. is synonymized under Camponotus edmondi . This revision also includes an identification key to species for both minor and major castes, information on geographic distribution and biology, taxonomic discussions, and descriptions of intraspecific variation. Traditional taxonomy and multivariate morphometric analysis are independent sources of information which, in combination, allow more precise species delimitation. Moreover, quantitative characters included in identification keys improve accuracy of determination in difficult cases.

Abstract The Malagasy Camponotus edmondi species group is revised based on both qualitative morphological traits and multivariate analysis of continuous morphometric data. To minimize the effect of the scaling properties of diverse traits due to worker caste polymorphism, and to achieve the desired near-linearity of data, morphometric analyses were done only on minor workers. The majority of traits exhibit broken scaling on head size, dividing Camponotus workers into two discrete subcastes, minors and majors. This broken scaling prevents the application of algorithms that uses linear combination of data to the entire dataset, hence only minor workers were analyzed statistically. The elimination of major workers resulted in linearity and the data meet required assumptions. However, morphometric ratios for the subsets of minor and major workers were used in species descriptions and redefinitions. Prior species hypotheses and the goodness of clusters were tested on raw data by confirmatory linear discriminant analysis. Due to the small sample size available for some species, a factor known to reduce statistical reliability, hypotheses generated by exploratory analyses were tested with extreme care and species delimitations were inferred via the combined evidence of both qualitative (morphology and biology) and quantitative data. Altogether, fifteen species are recognized, of which 11 are new to science: Camponotus alamaina sp. n., Camponotus androy sp. n., Camponotus bevohitra sp. n., Camponotus galoko sp. n., Camponotus matsilo sp. n., Camponotus mifaka sp. n., Camponotus orombe sp. n., Camponotus tafo sp. n., Camponotus tratra sp. n., Camponotus varatra sp. n., and Camponotus zavo sp. n. Four species are redescribed: Camponotus echinoploides Forel, Camponotus edmondi André, Camponotus ethicus Forel, and Camponotus robustus Roger.

2016-06-01

In this paper we reflect on current trends and anticipate future prospects regarding qualitative research in Psychology. We highlight various institutional and disciplinary obstacles to qualitative research diversity, complexity and quality. At the same time, we note some causes for optimism, including publication breakthroughs and vitality within the field. The paper is structured into three main sections which consider: 1) the positioning of qualitative research within Psychology; 2) celebrating the different kinds of knowledge produced by qualitative research; and 3) implementing high quality qualitative research. In general we accentuate the positive, recognising and illustrating innovative qualitative research practices which generate new insights and propel the field forward. We conclude by emphasising the importance of research training: for qualitative research to flourish within Psychology (and beyond), students and early career researchers require more sophisticated, in-depth instruction than is currently offered.

Scholars who research phenomena of concern to the discipline of nursing are challenged with making wise choices about different qualitative research approaches. Ultimately, they want to choose an approach that is best suited to answer their research questions. Such choices are predicated on having made distinctions between qualitative methodology, methods, and analytic frames. In this article, we distinguish two qualitative research approaches widely used for descriptive studies: descriptive phenomenological and qualitative description. Providing a clear basis that highlights the distinguishing features and similarities between descriptive phenomenological and qualitative description research will help students and researchers make more informed choices in deciding upon the most appropriate methodology in qualitative research. We orient the reader to distinguishing features and similarities associated with each approach and the kinds of research questions descriptive phenomenological and qualitative description research address. © The Author(s) 2016.

2015-06-01

This paper originates from a panel discussion on the evaluation of "Ethics Educational Program in Health Sciences" held during the IAEE Conference 2014 Ankara, Turkey. The participants of the panel had consultations to solidify the concepts about the topic. The qualitative data out of these antecedent discussions became mature with the contributions in the panel. The outcome of this qualitative study mainly focuses on the examples of two current curricula; one from PhD on History of Medicine and Medical Ethics, the other one from an elective course on medical ethics as a part of a PhD program on Pharmacy Management and History, followed by the major challenges the trainees face during their education, their expectations and whether the program was satisfactory, the aspects of the programs which are prone to improvement and their overall evaluations of the programs.

Is the worldview of qualitative inquiry a proper guide for psychological research?

PubMed

Capaldi, E J; Proctor, Robert W

2005-01-01

Qualitative methods are becoming increasingly popular in psychology. Although the distinction between qualitative and quantitative often is stated in terms of methods, the real distinction is between worldviews: that favored by most qualitative methodologists, which emphasizes subjective experience and multiple realities, and that commonly accepted in science. The worldview accepted by most adherents of qualitative inquiry suggests the exclusive use of methods that include verbal reports of lived experience. Qualitative methods serve an important function in psychology, but their use as recommended by their adherents is limited in 2 respects: The adherents use a narrow and unconventional approach to qualitative methods that differs from that normally understood, and they favor use of a restricted range of qualitative methods over other qualitative methods and quantitative methods. If qualitative inquiry is to make a greater contribution to psychology, researchers in that tradition must acquire a better understanding of contemporary science, correct their misunderstandings of the rationale for quantitative methods, and address the apparent limitations of their methods emphasizing reported experience.

The synthesis of nanosized particles of Ag-doped hydroxyapatite with antibacterial properties is of great interest for the development of new biomedical applications. The aim of this study was the evaluation of Ca10−xAgx(PO4)6(OH)2 nanoparticles (Ag:HAp-NPs) for their antibacterial and antifungal activity. Resistance to antimicrobial agents by pathogenic bacteria has emerged in the recent years and became a major health problem. Here, we report a method for synthesizing Ag doped nanocrystalline hydroxyapatite. A silver-doped nanocrystalline hydroxyapatite was synthesized at 100°C in deionised water. Also, in this paper Ag:HAp-NPs are evaluated for their antimicrobial activity against Gram-positive and Gram-negative bacteria and fungal strains. The specific antimicrobial activity revealed by the qualitative assay is demonstrating that our compounds are interacting differently with the microbial targets, probably due to the differences in the microbial wall structures.

To explore the differences in perception of the medical response to the victims of the 2013 Boston Marathon bombings between laypeople and healthcare professionals. Commentary accessible and available on Internet discussion websites by non-medically trained persons and in the academic literature by healthcare professionals was analysed qualitatively. Major themes were found relating to both the pre-hospital and hospital-based phases of the medical response to the disaster. Laypeople focused more on pre-hospital care and the actions of specific bystanders, while healthcare professionals focused on hospital care, the importance of a disaster plan, and frequent training for the success of the response. Laypeople and healthcare professionals have positive but differing perceptions of the medical response to the victims of the bombings. This may have implications for future funding and implementation of disaster preparedness. © Royal Society for Public Health 2016.

The characterization of biological systems with respect to their behavior and functionality based on versatile biochemical interactions is a major challenge. To understand these complex mechanisms at systems level modeling approaches are investigated. Different modeling formalisms allow metabolic models to be analyzed depending on the question to be solved, the biochemical knowledge and the availability of experimental data. Here, we describe a method for an integrative analysis of the structure and dynamics represented by qualitative and quantitative metabolic models. Using various formalisms, the metabolic model is analyzed from different perspectives. Determined structural and dynamic properties are visualized in the contextmore » of the metabolic model. Interaction techniques allow the exploration and visual analysis thereby leading to a broader understanding of the behavior and functionality of the underlying biological system. The System Biology Metabolic Model Framework (SBM{sup 2} – Framework) implements the developed method and, as an example, is applied for the integrative analysis of the crop plant potato.« less

Phenomenal and access consciousness in olfaction.

PubMed

Stevenson, Richard J

2009-12-01

Contemporary literature on consciousness, with some exceptions, rarely considers the olfactory system. In this article the characteristics of olfactory consciousness, viewed from the standpoint of the phenomenal (P)/access (A) distinction, are examined relative to the major senses. The review details several qualitative differences in both olfactory P consciousness (shifts in the felt location, universal synesthesia-like and affect-rich experiences, and misperceptions) and A consciousness (recovery from habituation, capacity for conscious processing, access to semantic and episodic memory, learning, attention, and in the serial-unitary nature of olfactory percepts). The basis for these differences is argued to arise from the functions that the olfactory system performs and from the unique neural architecture needed to instantiate them. These data suggest, at a minimum, that P and A consciousness are uniquely configured in olfaction and an argument can be made that the P and A distinction may not hold for this sensory system.

Shaping LGBTQ Identities: Western Media Representations and LGBTQ People's Perceptions in Rural Spain.

PubMed

Sanz López, Josep Maria

2017-10-09

A growing academic discussion has focused on how, in a globalized world, LGBTQ identities are shaped and influenced by different and international actors, such as the media. This article analyzes how LGBTQ people from a rural region of a Western country-Spain-feel toward their representations on TV series from English-speaking countries. Employing a qualitative approach, this research aims to depict whether the academic conceptualizations to analyze these identity conformation processes are accurate. In addition, it explores how dominating media representations are being adapted in a region that, although within the West, can serve a context of a very different nature. The results found that a major rejection of the TV series representations among participants can suggest both an inaccuracy of the conceptualizations used by some scholars to understand LGBTQ flows and a problematic LGBTQ representation in media products that goes beyond regions and spaces.

Students' Ideas about How and Why Chemical Reactions Happen: Mapping the conceptual landscape

NASA Astrophysics Data System (ADS)

Yan, Fan; Talanquer, Vicente

2015-12-01

Research in science education has revealed that many students struggle to understand chemical reactions. Improving teaching and learning about chemical processes demands that we develop a clearer understanding of student reasoning in this area and of how this reasoning evolves with training in the domain. Thus, we have carried out a qualitative study to explore students reasoning about chemical causality and mechanism. Study participants included individuals at different educational levels, from college to graduate school. We identified diverse conceptual modes expressed by students when engaged in the analysis of different types of reactions. Main findings indicate that student reasoning about chemical reactions is influenced by the nature of the process. More advanced students tended to express conceptual modes that were more normative and had more explanatory power, but major conceptual difficulties persisted in their reasoning. The results of our study are relevant to educators interested in conceptual development, learning progressions, and assessment.

2009-01-01

Accompanying the rise in the number of mental health agency personnel tasked with quality assurance and improvement (QA/I) responsibilities is an increased need to understand the nature of the work these professionals undertake. Four aspects of the work of quality assurance and improvement (QA/I) professionals in mental health were explored in this qualitative study: their perceived roles, their major activities, their QA/I targets, and their contributions. In-person interviews were conducted with QA/I professionals at 16 mental health agencies. Respondents perceived their roles at varying levels of complexity, focused on different targets, and used different methods to conduct their work. Few targets of QA/I work served as indicators of high quality care. Most QA/I professionals provided concrete descriptions of how they had improved agency services, while others could describe none. Accreditation framed much of agency QA/I work, perhaps to its detriment. PMID:18688707

The implementation of accountable care organizations (ACOs), a new health care payment and delivery model designed to improve care and lower costs, is proceeding rapidly. We build on our experience tracking early ACOs to identify the major factors-such as contract characteristics; structure, capabilities, and activities; and local context-that would be likely to influence ACO formation, implementation, and performance. We then propose how an ACO evaluation program could be structured to guide policy makers and payers in improving the design of ACO contracts, while providing insights for providers on approaches to care transformation that are most likely to be successful in different contexts. We also propose key activities to support evaluation of ACOs in the near term, including tracking their formation, developing a set of performance measures across all ACOs and payers, aggregating those performance data, conducting qualitative and quantitative research, and coordinating different evaluation activities.

Background Qualitative research findings are increasingly used to inform decision-making. Research has indicated that not all quantitative research on the effects of interventions is disseminated or published. The extent to which qualitative researchers also systematically underreport or fail to publish certain types of research findings, and the impact this may have, has received little attention. Methods A survey was delivered online to gather data regarding non-dissemination and dissemination bias in qualitative research. We invited relevant stakeholders through our professional networks, authors of qualitative research identified through a systematic literature search, and further via snowball sampling. Results 1032 people took part in the survey of whom 859 participants identified as researchers, 133 as editors and 682 as peer reviewers. 68.1% of the researchers said that they had conducted at least one qualitative study that they had not published in a peer-reviewed journal. The main reasons for non-dissemination were that a publication was still intended (35.7%), resource constraints (35.4%), and that the authors gave up after the paper was rejected by one or more journals (32.5%). A majority of the editors and peer reviewers “(strongly) agreed” that the main reasons for rejecting a manuscript of a qualitative study were inadequate study quality (59.5%; 68.5%) and inadequate reporting quality (59.1%; 57.5%). Of 800 respondents, 83.1% “(strongly) agreed” that non-dissemination and possible resulting dissemination bias might undermine the willingness of funders to support qualitative research. 72.6% and 71.2%, respectively, “(strongly) agreed” that non-dissemination might lead to inappropriate health policy and health care. Conclusions The proportion of non-dissemination in qualitative research is substantial. Researchers, editors and peer reviewers play an important role in this. Non-dissemination and resulting dissemination bias may impact on health care research, practice and policy. More detailed investigations on patterns and causes of the non-dissemination of qualitative research are needed. PMID:27487090

2012-03-01

Data analysis is a complex and contested part of the qualitative research process, which has received limited theoretical attention. Researchers are often in need of useful instructions or guidelines on how to analyze the mass of qualitative data, but face the lack of clear guidance for using particular analytic methods. The aim of this paper is to propose and discuss the Qualitative Analysis Guide of Leuven (QUAGOL), a guide that was developed in order to be able to truly capture the rich insights of qualitative interview data. The article describes six major problems researchers are often struggling with during the process of qualitative data analysis. Consequently, the QUAGOL is proposed as a guide to facilitate the process of analysis. Challenges emerged and lessons learned from own extensive experiences with qualitative data analysis within the Grounded Theory Approach, as well as from those of other researchers (as described in the literature), were discussed and recommendations were presented. Strengths and pitfalls of the proposed method were discussed in detail. The Qualitative Analysis Guide of Leuven (QUAGOL) offers a comprehensive method to guide the process of qualitative data analysis. The process consists of two parts, each consisting of five stages. The method is systematic but not rigid. It is characterized by iterative processes of digging deeper, constantly moving between the various stages of the process. As such, it aims to stimulate the researcher's intuition and creativity as optimal as possible. The QUAGOL guide is a theory and practice-based guide that supports and facilitates the process of analysis of qualitative interview data. Although the method can facilitate the process of analysis, it cannot guarantee automatic quality. The skills of the researcher and the quality of the research team remain the most crucial components of a successful process of analysis. Additionally, the importance of constantly moving between the various stages throughout the research process cannot be overstated. Copyright © 2011 Elsevier Ltd. All rights reserved.

Telemedicine holds promise in bridging the gap between homebound patients and high quality health care, but uptake of such technology remains limited. Qualitative interviews conducted with 17 homebound patients found two major barriers to telemedicine. First, participants who lack familiarity with technology are hesitant about telemedicine, as baseline use of technology in the home is limited, participants did not feel capable of learning, and the advantages of telemedicine were unclear. Second, homebound patients place a high value on in-office visits due to therapeutic benefit, face-to-face communication, and the social aspect of medical appointments.

To analyze the contents of "bath salt" products purchased from California stores and the Internet qualitatively and quantitatively in a comprehensive manner. A convenience sample of "bath salt" products were purchased in person by multiple authors at retail stores in six California cities and over the Internet (U.S. sites only), between August 11, 2011 and December 15, 2011. Liquid chromatography-time-of-flight mass spectrometry was utilized to identify and quantify all substances in the purchased products. Thirty-five "bath salt" products were purchased and analyzed. Prices ranged from $9.95 to 49.99 (U.S. dollars). Most products had a warning against use. The majority (32/35, 91%) had one (n = 15) or multiple cathinones (n = 17) present. Fourteen different cathinones were identified, 3,4-methylenedioxypyrovalerone (MDPV) being the most common. Multiple drugs found including cathinones (buphedrone, ethcathinone, ethylone, MDPBP, and PBP), other designer amines (ethylamphetamine, fluoramphetamine, and 5-IAI), and the antihistamine doxylamine had not been previously identified in U.S. "bath salt" products. Quantification revealed high stimulant content and in some cases dramatic differences in either total cathinone or synthetic stimulant content between products with the same declared weight and even between identically named and outwardly appearing products. Comprehensive analysis of "bath salts" purchased from California stores and the Internet revealed the products to consistently contain cathinones, alone, or in different combinations, sometimes in high quantity. Multiple cathinones and other drugs found had not been previously identified in U.S. "bath salt" products. High total stimulant content in some products and variable qualitative and quantitative composition amongst products were demonstrated.

Neutering of cats and dogs in Ireland; pet owner self-reported perceptions of enabling and disabling factors in the decision to neuter

Devitt, Catherine; Downes, Marie T.; More, Simon J.

Background. Failure among pet owners to neuter their pets results in increased straying and overpopulation problems. Variations in neutering levels can be explained by cultural differences, differences in economic status in rural and urban locations, and owner perceptions about their pet. There are also differences between male and female pet owners. There is no research pertaining to Irish pet owner attitudes towards neutering their pets. This paper identified the perceptions of a sample of Irish cat and dog owners that influenced their decisions on pet neutering. Methods. This study was conducted using social science (qualitative) methods, including an interview-administered survey questionnaire and focus group discussions. Data was coded and managed using Nvivo 8 qualitative data analysis software. Results. Focus groups were conducted with 43 pet (cats and dogs) owners. Two major categories relating to the decision to neuter were identified: (1) enabling perceptions in the decision to neuter (subcategories were: controlling unwanted pet behaviour; positive perceptions regarding pet health and welfare outcomes; perceived owner responsibility; pet function; and the influence of veterinary advice), and (2) disabling perceptions in the decision to neuter (subcategories were: perceived financial cost of neutering; perceived adequacy of existing controls; and negative perceptions regarding pet health and welfare outcomes). Discussion. Pet owner sense of responsibility and control are two central issues to the decision to neuter their pets. Understanding how pet owners feel about topics such as pet neutering, can help improve initiatives aimed at emphasising the responsibility of population control of cats and dogs. PMID:26312187

Synthesis of qualitative studies is an emerging area that has been gaining more interest as an important source of evidence for improving health care policy and practice. In the last decade there have been numerous attempts to develop methods of aggregating and synthesizing qualitative data. Although numerous empirical qualitative studies have been published about different aspects of health care research, to date, the aggregation and syntheses of these data has not been commonly reported, particularly in pharmacy practice related research. This paper describes different methods of conducting meta-synthesis and provides an overview of selected common methods. The paper also emphasizes the challenges and opportunities associated with conducting meta-synthesis and highlights the importance of meta-synthesis in informing practice, policy and research.

Trans people's experiences with assisted reproduction services: a qualitative study.

What are the experiences of trans persons (i.e. those whose gender identity does not match the gender assigned to them at birth) who sought or accessed assisted reproduction (AR) services in Ontario, Canada, between 2007 and 2010? The majority of trans persons report negative experiences with AR service providers. Apart from research examining desire to have children among trans people, most of the literature on this topic has debated the ethics of assisting trans persons to become parents. To-date, all of the published research concerning trans persons' experiences with AR services is solely from the perspective of service providers; no studies have examined the experiences of trans people themselves. Secondary qualitative research study of data from nine trans-identified people and their partners (total n = 11) collected as part of a community-based study of access to AR services for sexual and gender minority people between 2010 and 2012. Trans-identified volunteers (and their partners, when applicable) who had used or attempted to access AR services since 2007 from across Ontario, Canada, participated in a 60-90 minute, semi-structured qualitative interview. Qualitative analysis was performed using a descriptive phenomenological approach. Emerging themes were continually checked against the data as part of an iterative process. The data highlight barriers to accessing AR services for trans people. Participant recommendations for improving AR service provision to better meet the needs of this population are presented. These recommendations address the following areas: (i) AR service provider education and training; (ii) service provider and clinic practices and (iii) clinic environment. The majority of study participants were trans people who identified as men and who resided in major urban areas; those living in smaller communities may have different experiences that were not adequately captured in this analysis. While existing literature debates the ethics of assisting trans people to become parents through the use of AR, our study demonstrates that they are already accessing or attempting to access these services. This reality necessitates a shift toward exploring the ways in which AR services can be improved to better meet the needs of this population, from the perspectives of both service users and service providers.

2014-07-01

Past studies investigating university level students' views of nature of science (NOS) were relatively few and most of them were conducted in Western countries. This paper focuses upon comparing the quantitative patterns in Western (US Caucasian and African-American) and non-Western (Taiwanese) students' views of NOS (VNOS) by adopting a survey instrument. This analysis combined with qualitative data begin to uncover details of potential cultural differences in patterns specifically in the US educational context by comparing Caucasian and African-American student responses to a question from a commonly used assessment of VNOS. Results show different patterns of views along the four dimensions of NOS (social negotiation, invented/creative NOS, cultural impacts, and changing/tentative feature of science) according to student major, student gender, and student ethnicity. These differences and similarities have the potential to impact undergraduate education and underrepresentation of cultural minorities in science careers and call for further research into NOS views in the context of diverse student groups.

In this study, a method of metabolite profiling based on UPLC-QTOF/MS was developed to analyze Platycodon grandiflorum. In the optimal UPLC, various metabolites, including major platycosides, were separated well in 15 min. The metabolite extraction protocols were also optimized by selecting a solvent for use in the study, the ratio of solvent to sample and sonication time. This method was used to profile two different parts of P. grandiflorum, i.e., the roots of P. grandiflorum (PR) and the stems and leaves of P. grandiflorum (PS), in the positive and negative ion modes. As a result, PR and PS showed qualitatively and quantitatively different metabolite profiles. Furthermore, their metabolite compositions differed according to individual plant samples. These results indicate that the UPLC-QTOF/MS-based profiling method is a good tool to analyze various metabolites in P. grandiflorum. This metabolomics approach can also be applied to evaluate the overall quality of P. grandiflorum, as well as to discriminate the cultivars for the medicinal plant industry.

In this study, a method of metabolite profiling based on UPLC-QTOF/MS was developed to analyze Platycodon grandiflorum. In the optimal UPLC, various metabolites, including major platycosides, were separated well in 15 min. The metabolite extraction protocols were also optimized by selecting a solvent for use in the study, the ratio of solvent to sample and sonication time. This method was used to profile two different parts of P. grandiflorum, i.e., the roots of P. grandiflorum (PR) and the stems and leaves of P. grandiflorum (PS), in the positive and negative ion modes. As a result, PR and PS showed qualitatively and quantitatively different metabolite profiles. Furthermore, their metabolite compositions differed according to individual plant samples.

Andean potatoes are gaining popularity not only for their appealing colors and culinary uses but also for their potential higher content of polyphenolic compounds. The objective of this study was to identify potato varieties with increased phenolic content. This was achieved through characterization and quantitation of the phenolic composition in 20 varieties of native Andean potatoes from 4 different Solanum species with different colors. Major quantitative and qualitative differences among evaluated samples were more dependent on the coloration of the extracted sample rather than on the species. The most predominant anthocyanidins were petunidin-3-coumaroylrutinoside-5-glucoside and pelargonidin-3-coumaroylrutinoside-5-glucoside in purple and red potato extracts, respectively, while chlorogenic acid and its isomers were the main phenolic compund (43% of the total phenolic content). Our study suggested that the appropriate selection of native potatoes could provide new sources of polyphenolics with health promoting properties and natural pigments with increased stability for food applications.

2005-06-01

The importance of attitudes toward science has risen from widely accepted assumptions that achievement and attitude are positively interdependent and that affective variables are as important as cognitive variables in molding student learning. This report examines the effect on student attitudes toward learning chemistry in an active learning environment that has incorporated elements believed to positively influence student attitudes toward science including cooperative learning, hands-on activities, real-world applications, and engaging technology. These elements were considered for synergetic effects and not as individual contributors to the overall results. Two different sections of the same general chemistry course participated. The lecture setting was used as the control. Residualized gain scores were used to compare net changes in student attitudes. Data were analyzed for possible differences in gain for different academic majors. Anxiety in chemistry was monitored for the two class settings in three areas, learning in chemistry, chemistry evaluation, and chemical handling. Qualitative student feedback was also collected and is summarized in this report on the attitudinal aspects of instruction.

Trace chemical contaminants generated by human metabolism is a major source of contamination in spacecraft crew module. In this research, types and generation rates of pollutants from human metabolism were determined in the Chinese diets. Expired air, skin gas, and sweat of 20 subjects were analyzed at different exercise states in a simulated module. The exercise states were designed according to the basic activities in the orbit of astronauts. Qualitative and quantitative analyses of contaminants generated by human metabolic were performed with gas chromatography/mass spectrometry, gas chromatography and UV spectrophotometer. Sixteen chemical compounds from metabolic sources were found. With the increase in physical load, the concentrations of chemical compounds from human skin and expired air correspondingly increased. The species and the offgassing rates of pollutants from human metabolism are different among the Chinese, Americans and the Russians due to differences in ethnicity and dietary customs. This research provides data to aid in the design, development and operation of China's long duration space mission.

Interprofessional relationship plays a major role in effective patient care. Specialized units such as critical care require multidisciplinary care where perception about every members role may affect the delivery of patient care. The objective of this study was to find out nurses' perceptions of the role of physiotherapists in the critical care team. Qualitative study by using semi-structured interview was conducted among the qualified nurses working in the Intensive Care Unit of a tertiary care hospital. The interview consisted of 19 questions divided into 3 sections. Interviews were audio recorded and transcribed. In-depth content analysis was carried out to identify major themes in relation to the research question. Analysis identified five major issues which included role and image of a physiotherapist, effectiveness of treatment, communications, teamwork, and interprofessional relations. Physiotherapists were perceived to be an important member of the critical team with the role of mobilizing the patients. The respondents admitted that there existed limitations in interprofessional relationship. Nurses perceived the role of physiotherapist in the critical care unit as an integral part and agreed on the need for inclusion of therapist multidisciplinary critical care team.

The volatile components of 20 mango cultivars were investigated by means of simultaneous distillation-extraction, GC, and GC-MS. Three hundred and seventy-two compounds were identified, of which 180 were found for the first time in mango fruit. The total concentration of volatiles was approximately 18-123 mg/kg of fresh fruit. Terpene hydrocarbons were the major volatiles of all cultivars, the dominant terpenes being delta-3-carene (cvs. Haden, Manga amarilla, Macho, Manga blanca, San Diego, Manzano, Smith, Florida, Keitt, and Kent), limonene (cvs. Delicioso, Super Haden, Ordonez, Filipino, and La Paz), both terpenes (cv. Delicia), terpinolene (cvs. Obispo, Corazon, and Huevo de toro), and alpha-phellandrene (cv. Minin). Other qualitative and quantitative differences among the cultivars could be demonstrated.

Being Accountable or Filling in Forms: Managers and Clinicians' Views About Communicating Risk.

2017-01-01

Assessment, documentation, and prevention of risk are central to mental health services. However, there is a paucity of research examining how risk is perceived by key stakeholders including managers and clinicians. Qualitative, exploratory design. In-depth interviews were held with 22 senior managers and 21 clinicians. Communicating risk was a major theme to emerge. For managers, accountability was a primary consideration in communicating risk and therefore influential over nursing practice. Clinicians were more likely to view the organizational processes of communicating risk as a bureaucratic exercise. The significant difference between managers and clinicians is problematic for achieving consumer-focused mental health service delivery, a more critical approach to risk is essential in preserving the therapeutic relationship. © 2015 Wiley Periodicals, Inc.

Although social networks are essential for explaining protective and risk factors among homeless youth, little is known about the formation and composition of these groups. In this study, we utilized 19 in-depth interviews with homeless youth to investigate their social network formation, role relationships, housing status, and network member functions. Our findings reveal that the formation of these networks occurred in different ways including meeting network members through others or in specific social situations. The majority of social network members were currently housed and provided various functions including instrumental and social support and protection. Responses from participants provide valuable insight into the formation of social networks and potentially explain their subsequent involvement in risky behaviors. PMID:22121330

A qualitative study was conducted to understand college students’ experiences and perceptions of sexual communication and sexual goals, and how they were affected by the transition from high school to college. Participants were heterosexual college students (N = 29). Single-sex focus groups were conducted and analyzed for themes. Major themes included gender differences in communication of sexual interest, with men reportedly perceiving more sexualized intentions than women intended to communicate. Gender similarities were observed related to preferring indirect and nonverbal communication and to having more freedom to pursue sexual goals in college. Men focused more intently on casual sex goals, whereas women reported more relationship goals and concerns about reputation. PMID:20502624

Traditional biomass has been the major source of cooking energy for major segment of Ethiopian population for thousands of years. Cognizant of this energy poverty, the Government of Ethiopia has been spending huge sum of money to increase hydroelectric power generating stations. To assess current levels and correlates of traditional cooking energy sources utilization. A community based cross-sectional study was conducted employing both quantitative and qualitative approaches on systematically selected 423 households for quantitative and purposively selected 20 people for qualitative parts. SPSS version 16 for windows was used to analyze the quantitative data. Logistic regression was fitted to assess possible associations and its strength was measured using odds ratio at 95% CI. Qualitative data were analyzed thematically. The study indicated that 95% of households still use traditional biomass for cooking. Those who were less knowledgeable about negative health and environmental effects of traditional cooking energy sources were seven and six times more likely to utilize them compared with those who were knowledgeable (AOR (95% CI) = 7.56 (1.635, 34.926), AOR (95% CI) = 6.68 (1.80, 24.385), resp.). The most outstanding finding of this study was that people use traditional energy for cooking mainly due to lack of the knowledge and their beliefs about food prepared using traditional energy. That means "...people still believe that food cooked with charcoal is believed to taste delicious than cooked with other means."  The majority of households use traditional biomass for cooking due to lack of knowledge and belief. Therefore, mechanisms should be designed to promote electric energy and to teach the public about health effects of traditional cooking energy source.

To determine patient perceptions of joint teleconsultations (JTC), with particular reference to reasons underlying, and factors contributing to, patient satisfaction and dissatisfaction with this mode of health delivery. Telemedicine has been welcomed as one way of improving health-care delivery, by improving patient access to secondary care and specialist services hence widening patient choice, particularly for patients outside major conurbations. However, a recent systematic review found currently available data on patient satisfaction with telemedicine to be methodologically flawed. Qualitative evaluations offer the opportunity to elucidate the details of patient satisfaction with this mode of health-care delivery. Qualitative study using semi-structured interviews. Purposive sample of 28 participants of a major randomized controlled trial (Virtual Outreach study) of JTC conducted in one urban and one rural area in Britain. Joint teleconferenced consultations with the patient, patient's general practitioner (GP), and a hospital specialist. The patient and GP were sited in the local practice, while the hospital specialist was in the hospital outpatient department, and the two parties were connected by an ISDN2 link and video-conferencing software. Patient experiences of JTC, with particular reference to reasons underlying, and factors contributing to, overall satisfaction or dissatisfaction. Two major themes were identified: customer care and doctor-patient interaction. Patients appreciated the customer care aspects of JTC, particularly the enhanced convenience, reduced costs and improved punctuality associated with JTC. However, there were divergent views about the doctor-patient interactions with some patients expressing a sense of alienation arising from the use of technology, and problems with doctor-patient communication. These data add significantly to the existing literature on patient satisfaction with telemedicine, by elucidating the factors underlying overall satisfaction scores and hence have implications for future service delivery and implementation of telemedicine.

Knowledge of the 3D structure of the binding groove of major histocompatibility (MHC) molecules, which play a central role in the immune response, is crucial to shed light into the details of peptide recognition and polymorphism. This work reports molecular modeling studies aimed at providing 3D models for two class I and two class II MHC alleles from Salmo salar (Sasa), as the lack of experimental structures of fish MHC molecules represents a serious limitation to understand the specific preferences for peptide binding. The reliability of the structural models built up using bioinformatic tools was explored by means of molecular dynamics simulations of their complexes with representative peptides, and the energetics of the MHC-peptide interaction was determined by combining molecular mechanics interaction energies and implicit continuum solvation calculations. The structural models revealed the occurrence of notable differences in the nature of residues at specific positions in the binding groove not only between human and Sasa MHC proteins, but also between different Sasa alleles. Those differences lead to distinct trends in the structural features that mediate the binding of peptides to both class I and II MHC molecules, which are qualitatively reflected in the relative binding affinities. Overall, the structural models presented here are a valuable starting point to explore the interactions between MHC receptors and pathogen-specific interactions and to design vaccines against viral pathogens.

Evaluating a multi-criteria model for hazard assessment in urban design. The Porto Marghera case study

The aim of this paper is to describe a new approach to major industrial hazard assessment, which has been recently studied by the authors in conjunction with the Italian Environmental Protection Agency ('ARPAV'). The real opportunity for developing a different approach arose from the need of the Italian EPA to provide the Venice Port Authority with an appropriate estimation of major industrial hazards in Porto Marghera, an industrial estate near Venice (Italy). However, the standard model, the quantitative risk analysis (QRA), only provided a list of individual quantitative risk values, related to single locations. The experimental model is based onmore » a multi-criteria approach--the Analytic Hierarchy Process--which introduces the use of expert opinions, complementary skills and expertise from different disciplines in conjunction with quantitative traditional analysis. This permitted the generation of quantitative data on risk assessment from a series of qualitative assessments, on the present situation and on three other future scenarios, and use of this information as indirect quantitative measures, which could be aggregated for obtaining the global risk rate. This approach is in line with the main concepts proposed by the last European directive on Major Hazard Accidents, which recommends increasing the participation of operators, taking the other players into account and, moreover, paying more attention to the concepts of 'urban control', 'subjective risk' (risk perception) and intangible factors (factors not directly quantifiable)« less

This study implements qualitative and quantitative methodologies in the development of a culturally appropriate instrument of stress for Mexican immigrant farmworkers. Focus groups were used to uncover culturally based perspectives on life stressors, definitions of stress, and stress mediators. Qualitative data were analyzed using QSR NVivo and then used to develop a 23-item stress scale. The scale was tested for reliability and validity in an independent sample and demonstrates excellent reliability (α = 0.9123). Test-retest coefficients of the stress scale are also strong (r = 0.8344, p = 0.0000). Qualitative analyses indicated three major sources of stress: work, family, and community. Emotional aspects of stress also emerged, demonstrating a cultural perspective of stress closely related to feelings of despair and not being able to find a way out of despairing situations. This paper reveals themes gathered from the qualitative data and identifies reliability and validity constructs associated with the scale. The stress scale developed as part of this investigation is a reliable and culturally appropriate instrument for assessing stress among Mexican immigrant farmworkers. PMID:17955350

Qualitative biomechanical principles for application in coaching.

2007-01-01

Many aspects of human movements in sport can be readily understood by Newtonian rigid-body mechanics. Many of these laws and biomechanical principles, however, are counterintuitive to a lot of people. There are also several problems in the application of biomechanics to sports, so the application of biomechanics in the qualitative analysis of sport skills by many coaches has been limited. Biomechanics scholars have long been interested in developing principles that facilitate the qualitative application of biomechanics to improve movement performance and reduce the risk of injury. This paper summarizes the major North American efforts to establish a set of general biomechanical principles of movement, and illustrates how principles can be used to improve the application of biomechanics in the qualitative analysis of sport technique. A coach helping a player with a tennis serve is presented as an example. The standardization of terminology for biomechanical principles is proposed as an important first step in improving the application ofbiomechanics in sport. There is also a need for international cooperation and research on the effectiveness of applying biomechanical principles in the coaching of sport techniques.

Hadi, Muhammad Abdul; José Closs, S

2016-06-01

The use of qualitative research methodology is well established for data generation within healthcare research generally and clinical pharmacy research specifically. In the past, qualitative research methodology has been criticized for lacking rigour, transparency, justification of data collection and analysis methods being used, and hence the integrity of findings. Demonstrating rigour in qualitative studies is essential so that the research findings have the "integrity" to make an impact on practice, policy or both. Unlike other healthcare disciplines, the issue of "quality" of qualitative research has not been discussed much in the clinical pharmacy discipline. The aim of this paper is to highlight the importance of rigour in qualitative research, present different philosophical standpoints on the issue of quality in qualitative research and to discuss briefly strategies to ensure rigour in qualitative research. Finally, a mini review of recent research is presented to illustrate the strategies reported by clinical pharmacy researchers to ensure rigour in their qualitative research studies.

How does reviewing the evidence change veterinary surgeons' beliefs regarding the treatment of ovine footrot? A quantitative and qualitative study.

Footrot is a widespread, infectious cause of lameness in sheep, with major economic and welfare costs. The aims of this research were: (i) to quantify how veterinary surgeons' beliefs regarding the efficacy of two treatments for footrot changed following a review of the evidence (ii) to obtain a consensus opinion following group discussions (iii) to capture complementary qualitative data to place their beliefs within a broader clinical context. Grounded in a Bayesian statistical framework, probabilistic elicitation (roulette method) was used to quantify the beliefs of eleven veterinary surgeons during two one-day workshops. There was considerable heterogeneity in veterinary surgeons' beliefs before they listened to a review of the evidence. After hearing the evidence, seven participants quantifiably changed their beliefs. In particular, two participants who initially believed that foot trimming with topical oxytetracycline was the better treatment, changed to entirely favour systemic and topical oxytetracycline instead. The results suggest that a substantial amount of the variation in beliefs related to differences in veterinary surgeons' knowledge of the evidence. Although considerable differences in opinion still remained after the evidence review, with several participants having non-overlapping 95% credible intervals, both groups did achieve a consensus opinion. Two key findings from the qualitative data were: (i) veterinary surgeons believed that farmers are unlikely to actively seek advice on lameness, suggesting a proactive veterinary approach is required (ii) more attention could be given to improving the way in which veterinary advice is delivered to farmers. In summary this study has: (i) demonstrated a practical method for probabilistically quantifying how veterinary surgeons' beliefs change (ii) revealed that the evidence that currently exists is capable of changing veterinary opinion (iii) suggested that improved transfer of research knowledge into veterinary practice is needed (iv) identified some potential obstacles to the implementation of veterinary advice by farmers.

Background Miscarriage affects around one in six pregnancies. Much research has taken place identifying the consequences of this for parents but is mainly quantitative. Of the limited qualitative studies, none have explored women's experiences of the methods of miscarriage management received. Aim To assess the social and personal impact of different management methods (expectant, medical and surgical) on women's experience of first trimester miscarriage. Design of study Qualitative interviews using a topic guide with a purposive cohort of four categories of women (each management method plus non-participants) 6 months to 1 year after first trimester miscarriage. Focus groups with both research participants and health workers. Setting Women from three hospitals in the South West of England that participated in the Miscarriage Treatment (MIST) trial. Method Seventy-two interviews were undertaken between September 1999 and June 2000. There were also five focus groups (47 participants) and two feedback sessions (8 participants) with written feedback from 12 women. Interviews lasted 0.5–2.5 hours generating over 2000 A4 pages of transcripts. The transcripts were analysed for common themes, using standard proformas, which were filled in by individual team members and then discussed by the whole research team. Iterative readings in the light of new emerging issues ensured that new themes could be identified throughout the analytical process. All transcripts were then encoded for the identified themes using NUDIST. Results Common themes emerged across all management options although some were specific to just one or two management options. The five major themes arising out of the data analysis were: intervention; experiences of care; finality; the ‘baby’; and pain and bleeding. Conclusions Women's experiences and beliefs vary widely and their preferences need to be considered in their early miscarriage management. The three methods have different benefits and problems from the women's point of view. Competence and caring from professionals are especially important. PMID:16536960

In this study, a systematic method was established for the holistic quality control of Ilex kudingcha C. J. Tseng, a popular functional drink for adjuvant treatment of diabetes, hypertension, obesity and hyperlipidemia. Both qualitative and quantitative analyses were conducted. For qualitative analysis, an ultra high performance liquid chromatography (UHPLC) coupled with an electrospray ionization quadrupole time-of-flight mass spectrometry (ESI-qTOF-MS) method was established for rapid separation and structural identification of the constituents in Ilex kudingcha. Samples were separated on an ACQUITY UPLC HSS T3C 18 column (2.1 mm × 100 mm, 1.8 μm) by gradient elution using 0.1% (v/v) formic acid (solvent A) and acetonitrile (solvent B) as mobile phases at a flow rate of 0.25 mL min -1 . The chromatographic profiling of Ilex kudingcha by UHPLC-qTOF-MS/MS resulted in the characterization of 53 compounds, comprising 18 compounds that were unambiguously identified by comparison with reference standards. For quantitative analysis, 18 major compounds from 15 batches of Ilex kudingcha samples were simultaneously detected by UPLC-DAD at wavelengths of 210 nm, 260 nm, and 326 nm. The method was validated with respect to precision, linearity, repeatability, stability, accuracy, and so on. The contents of the 18 target compounds were applied for hierarchical clustering analysis (HCA) and principal component analysis (PCA) to differentiate between the samples. The results of HCA and PCA were consistent with each other. Sample No. 1 differed significantly based on HCA and PCA, and the differentiating components were confirmed to originate from different batches of samples. Phenolic acids and triterpenes were found to be the main ingredients in Ilex kudingcha. This strategy was effective and straightforward, and provided a potential approach for holistic quality control of Ilex kudingcha. Copyright © 2018. Published by Elsevier B.V.

There may be features of depression in non-Western populations which are not captured in current diagnostic criteria or measurement tools, as well as criteria for depression that are not relevant in other regions. We investigated this possibility through a systematic review of qualitative studies of depression worldwide. Nine online databases were searched for records that used qualitative methods to study depression. Initial searches were conducted between August 2012 and December 2012; an updated search was repeated in June of 2015 to include relevant literature published between December 30, 2012 and May 30, 2015. No date limits were set for inclusion of articles. A total of 16,130 records were identified and 138 met full inclusion criteria. Included studies were published between 1976 and 2015. These 138 studies represented data on 170 different study populations (some reported on multiple samples) and 77 different nationalities/ethnicities. Variation in results by geographical region, gender, and study context were examined to determine the consistency of descriptions across populations. Fisher’s exact tests were used to compare frequencies of features across region, gender and context. Seven of the 15 features with the highest relative frequency form part of the DSM-5 diagnosis of Major Depressive Disorder (MDD). However, many of the other features with relatively high frequencies across the studies are associated features in the DSM, but are not prioritized as diagnostic criteria and therefore not included in standard instruments. The DSM-5 diagnostic criteria of problems with concentration and psychomotor agitation or slowing were infrequently mentioned. This research suggests that the DSM model and standard instruments currently based on the DSM may not adequately reflect the experience of depression at the worldwide or regional levels.

Footrot is a widespread, infectious cause of lameness in sheep, with major economic and welfare costs. The aims of this research were: (i) to quantify how veterinary surgeons’ beliefs regarding the efficacy of two treatments for footrot changed following a review of the evidence (ii) to obtain a consensus opinion following group discussions (iii) to capture complementary qualitative data to place their beliefs within a broader clinical context. Grounded in a Bayesian statistical framework, probabilistic elicitation (roulette method) was used to quantify the beliefs of eleven veterinary surgeons during two one-day workshops. There was considerable heterogeneity in veterinary surgeons’ beliefs before they listened to a review of the evidence. After hearing the evidence, seven participants quantifiably changed their beliefs. In particular, two participants who initially believed that foot trimming with topical oxytetracycline was the better treatment, changed to entirely favour systemic and topical oxytetracycline instead. The results suggest that a substantial amount of the variation in beliefs related to differences in veterinary surgeons’ knowledge of the evidence. Although considerable differences in opinion still remained after the evidence review, with several participants having non-overlapping 95% credible intervals, both groups did achieve a consensus opinion. Two key findings from the qualitative data were: (i) veterinary surgeons believed that farmers are unlikely to actively seek advice on lameness, suggesting a proactive veterinary approach is required (ii) more attention could be given to improving the way in which veterinary advice is delivered to farmers. In summary this study has: (i) demonstrated a practical method for probabilistically quantifying how veterinary surgeons’ beliefs change (ii) revealed that the evidence that currently exists is capable of changing veterinary opinion (iii) suggested that improved transfer of research knowledge into veterinary practice is needed (iv) identified some potential obstacles to the implementation of veterinary advice by farmers.

2013-01-01

A systematic review and synthesis of quantitative and qualitative research were undertaken to examine attitudes to deceased donation and registration as an organ donor among ethnic minorities in the U.K. and North America. A systematic search and assessments of relevance and quality were conducted. Parallel syntheses were then undertaken of 14 quantitative and 12 qualitative papers followed by their integration. The synthesis was organised around five barriers that emerged as key issues: (1) knowledge regarding deceased donation and registration as a donor; (2) discussion of donation/registration with family members; (3) faith and cultural beliefs; (4) bodily concerns including disfigurement and intactness; and (5) trust in doctors and the health care system. In all countries, knowledge of organ donation and registration remained low despite public campaigns, with African-Americans and Black African and Black Caribbean populations in the U.K. often regarding organ donation as a 'white' issue. Each of the four attitudinal barriers was also more prevalent among ethnic minorities compared with the majority population. However, the significance of trust and uncertainties regarding religion/faith differed between groups, reflecting salient aspects of ethnic identity and experiences. Differences were also identified within ethnic groups associated with age and generation, although respect for the views of elders often influenced younger peoples' willingness to donate. There is a need for a more nuanced understanding of ethnicity and of variations in attitudes associated with country of origin, age/generation, socio-economic status and area of residence, to inform public campaigns and promote sensitive discussions with bereaved ethnic minority families. The traditional focus on knowledge and attitudes also requires to be complemented by a greater emphasis on organisational and service-related barriers and changes required to enhance ethnic minorities' access to registration as a donor and consent to deceased donation.

Background Successful point-of-care testing, namely ensuring the completion of the test and treat cycle in the same encounter, has immense potential to reduce diagnostic and treatment delays, and impact patient outcomes. However, having rapid tests is not enough, as many barriers may prevent their successful implementation in point-of-care testing programs. Qualitative research on diagnostic practices may help identify such barriers across different points of care in health systems. Methods In this exploratory qualitative study, we conducted 78 semi-structured interviews and 13 focus group discussions in an urban and rural area of Karnataka, India, with healthcare providers (doctors, nurses, specialists, traditional healers, and informal providers), patients, community health workers, test manufacturers, laboratory technicians, program managers and policy-makers. Participants were purposively sampled to represent settings of hospitals, peripheral labs, clinics, communities and homes, in both the public and private sectors. Results In the Indian context, the onus is on the patient to ensure successful point-of-care testing across homes, clinics, labs and hospitals, amidst uncoordinated providers with divergent and often competing practices, in settings lacking material, money and human resources. We identified three overarching themes affecting point-of-care testing: the main theme is ‘relationships’ among providers and between providers and patients, influenced by the cross-cutting theme of ‘infrastructure’. Challenges with both result in ‘modified practices’ often favouring empirical (symptomatic) treatment over treatment guided by testing. Conclusions Even if tests can be conducted on the spot and infrastructure challenges have been resolved, relationships among providers and between patients and providers are crucial for successful point-of-care testing. Furthermore, these barriers do not act in isolation, but are interlinked and need to be examined as such. Also, a test alone has only limited power to overcome those difficulties. Test developers, policy-makers, healthcare providers and funders need to use these insights in overcoming barriers to point-of-care testing programs. PMID:26275231

Teaching of evolution in public schools: A cross-cultural examination

NASA Astrophysics Data System (ADS)

Stewart, Joshua M.

The current study sought to examine how the cultural settings of Colorado, United States, and Baden-Wurttemberg, Germany, influenced perspectives, understandings, and acceptance of college students who want to become teachers (i.e., prospective teachers) in regard to the theory of evolution, creationism, and intelligent design with both quantitative and qualitative components. The quantitative sample for the study consisted of 221 German prospective teachers from Baden-Wurttemberg and 231 United States prospective teachers from Colorado. The quantitative component consisted of a 42-item survey with both Likert and true/false items to examine how (1) country of origin, (2) religious participation, and (3) educational background influence students' views and understandings of the theory of evolution and alternative conceptions. Additionally, in a Likert 6-item motivated reasoning task (a theoretical construct), prospective teachers were asked to read and critique arguments supporting and opposing the theory of evolution; differences in how students critiqued arguments were hypothesized to demonstrate biases. For a separate sample from the same locations (8 German and 11 United States students), a qualitative component examined prospective teachers' positions on teaching the theory of evolution in public schools. Prospective teachers were asked to provide support for their position, anticipate opposing arguments, and implications that both positions would have for students. Lastly, prospective teachers were also asked to explain and define the theory of evolution. The current study aided in examining how teachers' perspectives, understandings, and acceptance impacted what was taught in the science classroom. The researcher found that country of origin, religious behavior, and educational background predicted prospective teachers' responses to numerous criterion variables used in the current study. Further, qualitative results expressed major differences between prospective teachers' views regarding the inclusion of evolution or alternative conceptions in public schools, between Colorado and Baden-Wurttemberg. As a potential indicator, findings from the current study may be useful in understanding potential differences between these two countries, in regard to perceptions of the theory of evolution and alternative conceptions. Further, findings from the current study might also inform how these topics might be covered in educational settings with a lowered risk of conflict.

Physical activity and sedentary behaviour are associated with health and wellbeing. Studies indicate that ethnic minority groups are both less active and more sedentary than the majority population and that factors influencing these behaviours may differ. Mapping the factors influencing physical activity and sedentary behaviour among ethnic minority groups living in Europe can help to identify determinants of physical activity and sedentary behaviour, research gaps and guide future research. A systematic mapping review was conducted to map the factors associated with physical activity and sedentary behaviour among ethnic minority groups living in Europe (protocol PROSPERO ID = CRD42014014575). Six databases were searched for quantitative and qualitative research published between 1999 and 2014. In synthesizing the findings, all factors were sorted and structured into clusters following a data driven approach and concept mapping. Sixty-three articles were identified out of 7794 returned by the systematic search. These included 41 quantitative and 22 qualitative studies. Of these 58 focused on physical activity, 5 on both physical activity and sedentary behaviour and none focused on sedentary behaviour. The factors associated with physical activity and sedentary behaviour were grouped into eight clusters. Social & cultural environment (n = 55) and Psychosocial (39) were the clusters containing most factors, followed by Physical environment & accessibility (33), Migration context (15), Institutional environment (14), Social & material resources (12), Health and health communication (12), Political environment (3). An important finding was that cultural and religious issues, in particular those related to gender issues, were recurring factors across the clusters. Physical activity and sedentary behaviour among ethnic minority groups living in Europe are influenced by a wide variety of factors, especially informed by qualitative studies. More comparative studies are needed as well as inclusion of a wider spectrum of the diverse ethnic minority groups resettled in different European countries. Few studies have investigated factors influencing sedentary behaviour. It is important in the future to address specific factors influencing physical activity and sedentary behaviour among different ethnic minority groups in order to plan and implement effective interventions.

To avoid false negative results, hepatitis B surface antigen (HBsAg) assays need to detect samples with mutations in the immunodominant 'a' determinant region, which vary by ethnographic region. We evaluated the prevalence and type of HBsAg mutations in a hepatitis B virus (HBV)-infected East- and Southeast Asian population, and the diagnostic performance of the Elecsys ® HBsAg II Qualitative assay. We analyzed 898 samples from patients with HBV infection from four sites (China [Beijing and Guangzhou], Korea and Vietnam). HBsAg mutations were detected and sequenced using highly sensitive ultra-deep sequencing and compared between the first (amino acids 124-137) and second (amino acids 139-147) loops of the 'a' determinant region using the Elecsys ® HBsAg II Qualitative assay. Overall, 237 distinct amino acid mutations in the major hydrophilic region were identified; mutations were present in 660 of 898 HBV-infected patient samples (73.5%). Within the pool of 237 distinct mutations, the majority of the amino acid mutations were found in HBV genotype C (64.8%). We identified 25 previously unknown distinct mutations, mostly prevalent in genotype C-infected Korean patients (n = 18) followed by Chinese (n = 12) patients. All 898 samples were correctly identified by the Elecsys ® HBsAg II Qualitative assay. We observed 237 distinct (including 25 novel) mutations, demonstrating the complexity of HBsAg variants in HBV-infected East- and Southeast Asian patients. The Elecsys ® HBsAg II Qualitative assay can reliably detect HBV-positive samples and is suitable for routine diagnostic use in East and Southeast Asia.

2010-02-01

The aim of this paper is to provide a descriptive review of published qualitative research studies on first episode psychosis (FEP). A review was undertaken to describe the findings of qualitative studies in early psychosis. Keyword searches in Medline, CINAHL, ASSIA, PsychINFO databases, as well as manual searches of other relevant journals and reference lists of primary papers, were conducted. Thirty-one qualitative papers (representing 27 discrete studies) were identified. The majority reported research concerning young people based in community settings. The research studies were organized according to the following generic social processes: (i) achieving identity; (ii) acquiring perspectives; (iii) doing activity; and, (iv) experiencing relationships. The papers reviewed are based on first-person accounts obtained from individuals who have experienced FEP, their family members and service providers. This descriptive review contributes to our understanding of the complex social processes of achieving identity, acquiring perspectives, doing activities and developing relationships as experienced by young people and the significant others in their world. The cumulative findings highlight the contextually rich and detailed information made possible through qualitative studies of FEP. They begin to account for the active engagement of individuals affected by psychosis in making sense of their experience and suggest that this experience should be understood from within young people's own framework of meaning.

Over 5 million children attend the Emergency Department (ED) annually in England with an ever-increasing paediatric emergency caseload echoed globally. Approximately 60% of children present with illness and the majority have non-urgent illness creating burgeoning pressures on children's ED and this crisis resonates globally. To date no qualitative systematic review exists that focuses on the parental reasons for childhood attendance at the ED in this sub-group. To identify parental reasons for attending ED for their children presenting with minor illness. A qualitative systematic review was conducted against inclusion/exclusion criteria. Five electronic databases and key journals were searched in June 2015. 471 studies were identified and following study selection, 4 qualitative studies were included. Nine themes were identified e.g. dissatisfaction with family medical services, perceived advantages of ED and 'child suffering' with novel and insightful sub-themes of 'hereditary anxiety', 'taking it off our hands', ED as a 'magical place'. This novel qualitative systematic review examined parental attendance presenting with childhood minor illness of interest to emergency care reformers and clinicians. ED attendance is complex and multifactorial but parents provide vital insight to ED reformers on parental reasons for ED attendance in this sub-group. Copyright © 2017 Elsevier Ltd.

Qualitative research on trainee well-being can add nuance to the understanding of propagators of burnout, and the role for interventions aimed at supporting well-being. This qualitative study was conducted to identify (i) situations and environments that cause stress for trainees, (ii) stress-reducing activities that trainees utilize, and (iii) whether trainees who report distress (high burnout and depression scores) describe different stressors and relaxation factors than those who do not. The study was conducted with a convenience sample of first-year medicine and psychiatry residents at a large urban teaching hospital. Participants were asked to complete electronic stress and relaxation diaries daily for 1 week. Diary entries were coded for recurrent themes. Participants were screened for burnout and depression. Codes were compared by subgroup based on baseline burnout and depression status to elucidate if specific themes emerged in these subgroups. Study sample included 51 interns. Sixteen (16/50, 32%) screened positive for burnout and three (3/50, 14%) had a positive depression screen. The most common stressors related to aspects of the learning environment, compounded by feeling under-equipped, overwhelmed, or out of time. The majority of relaxation activities involved social connection, food, other comforts, and occurred outside of the hospital environment. This study reveals that interns (regardless of burnout or depression screen) identify stressors that derive primarily from organizational, interpersonal, and cultural experiences of the learning environment; whereas relaxation themes are diversely represented across realms (home, leisure, social, health), though emphasize activities that occur outside of the work place.

Development and weighting of a life cycle assessment screening model

Bates, Wayne E.; O'Shaughnessy, James; Johnson, Sharon A.; Sisson, Richard

2004-02-01

Nearly all life cycle assessment tools available today are high priced, comprehensive and quantitative models requiring a significant amount of data collection and data input. In addition, most of the available software packages require a great deal of training time to learn how to operate the model software. Even after this time investment, results are not guaranteed because of the number of estimations and assumptions often necessary to run the model. As a result, product development, design teams and environmental specialists need a simplified tool that will allow for the qualitative evaluation and "screening" of various design options. This paper presents the development and design of a generic, qualitative life cycle screening model and demonstrates its applicability and ease of use. The model uses qualitative environmental, health and safety factors, based on site or product-specific issues, to sensitize the overall results for a given set of conditions. The paper also evaluates the impact of different population input ranking values on model output. The final analysis is based on site or product-specific variables. The user can then evaluate various design changes and the apparent impact or improvement on the environment, health and safety, compliance cost and overall corporate liability. Major input parameters can be varied, and factors such as materials use, pollution prevention, waste minimization, worker safety, product life, environmental impacts, return of investment, and recycle are evaluated. The flexibility of the model format will be discussed in order to demonstrate the applicability and usefulness within nearly any industry sector. Finally, an example using audience input value scores will be compared to other population input results.

We aimed to investigate the factors contributing to poor recruitment to the EaStER trial "Early Stage glottic cancer: Endoscopic excision or Radiotherapy" feasibility study. We performed a prospective qualitative assessment of the EaStER trial at three centres to investigate barriers to recruitment and implement changes. Methods used included semi-structured interviews, focus groups and audio-recordings of recruitment encounters. First, surgeons and recruiters did not all accept the primary outcome as the rationale for the trial. Surgeons did not always adhere to the trial eligibility criteria leading to variations between centres in the numbers of "eligible" patients. Second, as both treatments were considered equally successful, recruiters and patients focused on the pragmatics of the different trial arms, favouring surgery over radiotherapy. The lack of equipoise was reflected in the way recruiters presented trial information. Third, patient views, beliefs and preferences were not fully elicited or addressed by recruiters. Fourth, in some centres, logistical issues made trial participation difficult. This qualitative research identified several major issues that explained recruitment difficulties. While there was insufficient time to address these in the EaStER trial, several factors would need to be addressed to launch further RCTs in head and neck cancer. These include the need for clear ongoing agreement among recruiting clinicians regarding details in the study protocol; an understanding of the logistical issues hindering recruitment at individual centres; and training recruiters to enable them to explain the need for randomisation and the rationale for the RCT to patients.

Objective To identify major concerns associated with implantable cardioverter-defibrillators (ICDs) and to provide recommendations to adult and pediatric physicians involved in the care of patients with ICDs. Background Cardiac ion channelopathies are a well-recognized cause of sudden cardiac death in infants, children, adolescents, and young adults. ICDs are effective in preventing sudden death from fatal arrhythmias in patients with known cardiac channelopathies. There is a paucity of research on the effect of ICDs on quality of life in patients with cardiac channelopathy diagnoses, especially young patients. Methods A qualitative study interviewing patients and families affected by inherited arrhythmias was conducted. Fifty participants with personal or family histories of cardiac events or sudden death were interviewed individually or in focus groups by clinical psychologists. All interviews were transcribed verbatim and then analyzed and coded based on current qualitative research theory to identify themes related to the research question. Twenty-four participants discussed ICDs in their interviews. Results Participants reported concerns about ICDs, and these concerns were categorized into six themes: (1) comprehension and physician-patient communication; (2) anxiety; (3) restrictions and fallacies; (4) complications; (5) utility; and (6) alternative therapy. Participants noted communication breakdowns between providers and their colleagues, and between providers and their patients. Participants and their families experienced many different forms of anxiety, including worry about the aesthetics of the ICDs and fears of being shocked. Multiple restrictions, fallacies, and complications were also cited. Conclusion Interview themes were used to formulate recommendations for counseling and educating patients with ICDs. PMID:25383067

Background Cancer patients widely seek integrative oncology which embraces a wide variety of treatments and system approaches. Objective To investigate the concepts, therapeutic goals, procedures, and working conditions of integrative oncology doctors in the field of anthroposophic medicine. Methods This qualitative study was based on in-depth interviews with 35 highly experienced doctors working in hospitals and office-based practices in Germany and other countries. Structured qualitative content analysis was applied to examine the data. Results The doctors integrated conventional and holistic cancer concepts. Their treatments aimed at both tumor and symptom control and at strengthening the patient on different levels: living with the disease, overcoming the disease, enabling emotional and cognitive development, and addressing spiritual or transcendental issues according to the patient's wishes and initiatives. Therapeutic procedures were conventional anticancer and symptom-relieving treatments, herbal and mineral remedies, mistletoe therapy, art therapies, massages and other external applications, nutrition and lifestyle advice, psychological support, and multiple forms of empowerment. The approach emphasised good patient-doctor relationships and sufficient time for patient encounters and decision-making. Individualization appeared in several dimensions and was interwoven with standards and mindlines. The doctors often worked in teams and cooperated with other cancer care-related specialists. Conclusion Integrative cancer care pursues an individualized and patient-centered approach, encompassing conventional and multimodal complementary interventions, and addressing, along with physical and functional needs, the emotional and spiritual needs of patients. This seems to be important for tumor and symptom control, and addresses major challenges and important goals of modern cancer care. © The Author(s) 2016.

Balancing research interests and patient interests: a qualitative study into the intertwinement of care and research in paediatric oncology.

Traditionally, in ethical guidelines and in research ethics literature, care and research are clearly separated based on their different objectives. In contrast, in paediatric oncology, research and care are closely combined. Currently, it is unknown how relevant actors in paediatric oncology perceive this combination of research and care. We conducted a qualitative study into the experiences of those involved in Dutch paediatric oncology with the intertwinement of research and care and the dual role of paediatric oncologists as researchers and treating physicians. A qualitative study approach, using two focus groups and 19 semi-structured, in-depth interviews with paediatric oncologists, research coordinators, parents of children with cancer, and adolescents with cancer. Four themes characterize how actors experience the intertwinement of research and care in paediatric oncology. First, research is considered of major importance, and paediatric oncology professionals convey this message to patients and their parents. Second, there is ambiguity about categorization of studies into cancer therapy as either research or treatment. Third, role conflicts appear within the work of the paediatric oncologists. Finally, the various benefits of combining treatment with research are emphasized. Research is regarded as a fundamental and indispensable characteristic of paediatric oncology practice. Paediatric oncology professionals, parents, and patients have a very positive outlook on combining research and care, but they may not be sufficiently critical with respect to potential conflicts. Increased reflection on how to optimally combine research and care could serve as an important protection of the interests of children with cancer and their parents. © 2015 Wiley Periodicals, Inc.

Relevance of community structures and neighbourhood characteristics for participation of older adults: a qualitative study.

2016-01-01

Community and neighbourhood structures contribute not only to the health and well-being, but also to the participation of older adults. The degree of participation depends on both the living environment and the individual's personal characteristics, preferences and perception. However, there is still limited empirical evidence on how community and neighbourhood structures are linked to participation and health in the aged population. A qualitative exploratory approach was chosen with a series of problem-centred, semi-structured focus group discussions. Study participants were selected from within the city of Augsburg, Southern Germany, and from two municipalities in surrounding rural districts. The interviews took place in 2013. Structuring content analysis was used to identify key concepts. We conducted 11 focus group discussions with a total of 78 different study participants. The study participants (33 men and 45 women) had a mean age of 74 years (range 65-92 years). Only two study participants lived in an assisted living facility. Of all study participants, 77% lived in urban and 23% in rural areas. We extracted four metacodes ('Usual activities', 'Requirements for participation', 'Barriers to participation' and 'Facilitators for participation') and 15 subcodes. Health and poorly designed infrastructure were mentioned as important barriers to participation, and friendship and neighbourhood cohesion as important facilitators. This qualitative study revealed that poor design and accessibility of municipal infrastructure are major barriers to participation in old age in Germany. Community and neighbourhood structures can be part of the problem but also part of the solution when accessibility and social networks are taken into account.

The promotion of positive mental health is a becoming priority worldwide. Despite all the efforts invested in preventive and curative work, it is estimated that one in four persons will experience a mental health condition at some point in their lives. Even more worrying is the fact that up to a half of all mental health problems have their onset before the age of 14. Recent statistics (national and international surveys, meta-analyses, international reports) point out to the fact that child and adolescent mental health problems are on the rise. The present study will try to corroborate these results and further explore their meaning, by employing a sequential mixed methods research design (quantitative–qualitative). The quantitative part will analyze time trends using Health Behaviors in School-aged Children data (four survey cycles: 2002, 2006, 2010, 2014) on mental well-being from four European countries (the Czechia, Germany, Italy, and United Kingdom). The qualitative part will rely on focus groups to explore the perspectives of 13- and 15-year-old boys and girls on gender differences and on the changes in adolescent mental well-being over time, as well as measures through which these issues could be addressed. Thematic analysis will be employed to analyze qualitative data. The results of this study could make a major contribution to our understanding of the current trends in adolescent mental well-being, as well as the ways in which existing data could be linked to international and national health policies.

To explore nurse managers' behaviours, attitudes, perceived social norms, and behavioural control in the prevention and management of patient and visitor aggression in general hospitals. Patient and visitor aggression in general hospitals is a global problem that incurs substantial human suffering and organizational cost. Managers are key persons for creating low-aggression environments, yet their role and behaviours in reducing patient and visitor aggression remains unexplored. A qualitative descriptive study underpinned by the Reasoned Action Approach. Between October 2015-January 2016, we conducted five focus groups and 13 individual interviews with nurse leaders in Switzerland. The semi-structured interviews and focus groups were recorded, transcribed, and analysed in a qualitative content analysis. We identified three main themes: (i) Background factors: "Patient and visitor aggression is perceived through different lenses"; (ii) Determinants and intention: "Good intentions competing with harsh organizational reality"; (iii) Behaviours: "Preventing and managing aggressive behaviour and relentlessly striving to create low-aggression work environments". Addressing patient and visitor aggression is difficult for nurse managers due to a lack of effective communication, organizational feedback loops, protocols, and procedures that connect the situational and organizational management of aggressive incidents. Furthermore, tackling aggression at an organizational level is a major challenge for nurse managers due to scant financial resources and lack of interest. Treating patient and visitor aggression as a business case may increase organizational awareness and interest. Furthermore, clear communication of expectations, needs and resources could optimize support provision for staff. © 2017 John Wiley & Sons Ltd.

This qualitative study explored barriers to implementing evidence-based practices (EBPs) in community-based addiction treatment organizations (CBOs) by comparing staff descriptions of barriers for four EBPs: Motivational Interviewing (MI), Adolescent Community Reinforcement Approach (A-CRA), Assertive Community Treatment (ACT), and Cognitive-behavioral Therapy (CBT). The CBOs received CSAT/SAMHSA funding from 2003 to 2008 to deliver services using EBPs. Phone interview responses from 172 CBO staff directly involved in EBP implementation were analyzed using content analysis, a method for making inferences and developing themes from the systematic review of participant narratives (Berelson, 1952). Staff described different types of barriers to implementing each EBP. For MI, the majority of barriers involved staff resistance or organizational setting. For A-CRA, the majority of barriers involved specific characteristics of the EBP or client resistance. For CBT, the majority of barriers were associated with client resistance, and for ACT, the majority of barriers were associated with resources. EBP designers, policy makers who support EBP dissemination and funders should include explicit strategies to address such barriers. Addiction programs proposing to use specific EBPs must consider whether their programs have the organizational capacity and community capacity to meet the demands of the EBP selected.
