Factors influencing European consumer uptake of personalised nutrition. Results of a qualitative analysis.  

PubMed

The aim of this research was to explore consumer perceptions of personalised nutrition and to compare these across three different levels of "medicalization": lifestyle assessment (no blood sampling); phenotypic assessment (blood sampling); genomic assessment (blood and buccal sampling). The protocol was developed from two pilot focus groups conducted in the UK. Two focus groups (one comprising only "older" individuals between 30 and 60 years old, the other of adults 18-65 yrs of age) were run in the UK, Spain, the Netherlands, Poland, Portugal, Ireland, Greece and Germany (N=16). The analysis (guided using grounded theory) suggested that personalised nutrition was perceived in terms of benefit to health and fitness and that convenience was an important driver of uptake. Negative attitudes were associated with internet delivery but not with personalised nutrition per se. Barriers to uptake were linked to broader technological issues associated with data protection, trust in regulator and service providers. Services that required a fee were expected to be of better quality and more secure. An efficacious, transparent and trustworthy regulatory framework for personalised nutrition is required to alleviate consumer concern. In addition, developing trust in service providers is important if such services to be successful. PMID:23500415

Qualitative analysis of soft inflation  

NASA Astrophysics Data System (ADS)

In this paper we perform a qualitative analysis of the dynamical system resulting from the soft inflation scenario. This allows us to examine the various types of asymptotic behavior displayed by the system; we pay particular attention to the inflationary solutions given by Berkin, Maeda, and Yokoyama [Phys. Rev. Lett. 65, 141 (1990)]. We find that as ?-->?, no unique attracting critical point exists, but rather there exists a higher-dimensional set of critical points. It is shown that the solution given by Berkin, Maeda, and Yokoyama is representative of a class of solutions which asymptotically undergoes power-law inflation. Under the assumption that new inflation occurs, we show that, asymptotically, there exists a global attractor. Under the assumption that chaotic inflation occurs, we show that there exists an attractor for finite values of the field ? and that solutions which inflate will experience infinitely many inflationary eras.

Qualitative data analysis: conceptual and practical considerations.  

PubMed

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. PMID:19642962

Qualitative of analysis of MOS circuits  

NASA Astrophysics Data System (ADS)

With the push towards sub-micron technology, transistor models have become increasingly complex. The number of components in integrated circuits has forced designers' efforts and skills towards higher levels of design. This has created a gap between design expertise and the performance demands increasingly imposed by the technology. To alleviate this problem, software tools must be developed that provide the designer with expert advice on circuit performance and design. This requires a theory that links the intuitions of an expert circuit analyst with the corresponding principles of formal theory (i.e., algebra, calculus, feedback analysis, network theory, and electrodynamics), and that makes each underlying assumption explicit. Temporal Qualitative Analysis is a technique for analyzing the qualitative large signal behavior of MOS circuits that straddle the line between the digital and analog domains. Temporal Qualitative Analysis is based on the following four components: First, a qualitative representation is composed of a set of open regions separated by boundaries. These boundaries are chosen at the appropriate level of detail for the analysis. This concept is used in modeling time, space, circuit state variables, and device operating regions. Second, constraints between circuit state variables are established by circuit theory. At a finer time scale, the designer's intuition of electrodynamics is used to impose a casual relationship among these constraints. Third, large signal behavior is modeled by Transition Analysis, using continuity and theorems of calculus to determine how quantities pass between regions over time.

Blogging medical students: a qualitative analysis.  

PubMed

Purpose: Blogging is an increasingly popular method of sharing and reflecting on experiences of medical students in the World Wide Web with a potentially global learning community. The authors are not aware of studies that specifically examined blogs by medical students and thus for the first time investigated the type of experiences and impressions that emerged from these blogs with relevance for medical students and medical educators. Method: This was a qualitative study. Initially 75 blogs were identified. 33 blogs with a total of 1228 English and 337 German blog entries met the inclusion criteria and were analyzed. We started with line-by-line coding and switched to focused coding using constant comparative analysis to create a categorical framework for blogs. Results: Medical students use blogs to write and reflect about a large variety of issues related to medical school. Major emerging themes included the preparation for written and oral high-stakes exams, experiences during clinical rotations, dealing with distressing situations during medical school, and social life of students beyond medical school. Conclusions: Our findings suggest that blogs are a potentially useful tool for medical students to reflect on their experiences during medical school as well as for medical educators to better understand how students perceive their time in medical school. The educational benefit of blogging might even be increased if trained medical educators would help to facilitate meaningful and targeted discussions emerging from blog entries and comment on students' learning challenges with the chance to reach a large community of learners.

[Qualitative analysis: theory, steps and reliability].  

PubMed

This essay seeks to conduct in-depth analysis of qualitative research, based on benchmark authors and the author's own experience. The hypothesis is that in order for an analysis to be considered reliable, it needs to be based on structuring terms of qualitative research, namely the verbs 'comprehend' and 'interpret', and the nouns 'experience', 'common sense' and 'social action'. The 10 steps begin with the construction of the scientific object by its inclusion on the national and international agenda; the development of tools that make the theoretical concepts tangible; conducting field work that involves the researcher empathetically with the participants in the use of various techniques and approaches, making it possible to build relationships, observations and a narrative with perspective. Finally, the author deals with the analysis proper, showing how the object, which has already been studied in all the previous steps, should become a second-order construct, in which the logic of the actors in their diversity and not merely their speech predominates. The final report must be a theoretic, contextual, concise and clear narrative. PMID:22450402

How are patient characteristics relevant for physicians' clinical decision making in diabetes? An analysis of qualitative results from a cross-national factorial experiment.  

PubMed

Variations in medical practice have been widely documented and are a linchpin in explanations of health disparities. Evidence shows that clinical decision making varies according to patient, provider and health system characteristics. However, less is known about the processes underlying these aggregate associations and how physicians interpret various patient attributes. Verbal protocol analysis (otherwise known as 'think-aloud') techniques were used to analyze open-ended data from 244 physicians to examine which patient characteristics physicians identify as relevant for their decision making. Data are from a vignette-based factorial experiment measuring the effects of: (a) patient attributes (age, gender, race and socioeconomic status); (b) physician characteristics (gender and years of clinical experience); and (c) features of the healthcare system in two countries (USA, United Kingdom) on clinical decision making for diabetes. We find that physicians used patients' demographic characteristics only as a starting point in their assessments, and proceeded to make detailed assessments about cognitive ability, motivation, social support and other factors they consider predictive of adherence with medical recommendations and therefore relevant to treatment decisions. These non-medical characteristics of patients were mentioned with much greater consistency than traditional biophysiologic markers of risk such as race, gender, and age. Types of explanations identified varied somewhat according to patient characteristics and to the country in which the interview took place. Results show that basic demographic characteristics are inadequate to the task of capturing information physicians draw from doctor-patient encounters, and that in order to fully understand differential clinical decision making there is a need to move beyond documentation of aggregate associations and further explore the mental and social processes at work.

Qualitative content analysis of suicidal ideation in Korean college students.  

PubMed

The suicide rate for ages 15-24 increased recently in South Korea. The purpose of this study was to understand the suicidal ideation using the qualitative content analysis in South Korean college students. The data were collected with non-structured open questions in 134 college students and were analyzed with qualitative content analysis. The collected materials were classified 2 categories, 6 themes, and 21 theme clusters. Two categories are emerged: (1) facilitators of suicidal ideation, and (2) inhibitors of suicidal ideation. This study identified that the facilitators of suicidal ideation are physical, psychological and societal concerns, and suggested that the inhibitors of suicidal ideation are influenced by religious and cultural context. These results presented that Buddhism and Confucianism had influence on reasons to not attempting suicide behavior as the inhibitor of suicidal ideation. In conclusion, cultural context should be considered to develop strategies for the suicide prevention in South Korean college student. PMID:21706996

Correlation of qualitative and quantitative results from testing respirator fit  

SciTech Connect

Three qualitative respirator fit tests were evaluated for their ability to measure respiratory protection adequately. The methods were the negative pressure test, the isoamyl acetate test, and the irritant smoke test. Each test was performed concurrently with a single qualitative fit test, the dioctylphthalate (DOP) test, during 274 half-mask and 274 full face piece wearings. Most (95%) of the tested study had adequately fitting respirators as determined by quantitative testing. Of these subjects, 96-100% passed the qualitative fit tests. Of the 5% of the study subjects with inadequately fitting half-mask respirators, 93-100% of the inadequate fits were detected by qualitative methods. Twenty-three to 46% of the poorly fitting full face masks were detected by qualitative methods. The probability of passing or failing a qualitative test with an inadequately fitting respirator can be estimated; however, the uncertainty associated with each estimate is largely due to the small number of study subjects with poorly fitting respirators.

How to Use Qualitative Analysis to Support a DSA  

SciTech Connect

The use of judgement-based analyses that produces qualitative results can be a very effective method to demonstrate the safety posture of a nuclear facility. Such methodologies are recognized as appropriate through the graded approach established by the 10 CFR 830, Nuclear Safety Management and DOE-STD-3009. To successfully implement judgement-based analysis requires recognition of the uncertainties and biases that may be inherent with this approach. This paper will summarize the common errors that can occur when conducting judgement-based analyses and recommend techniques to improve the reproducibility and accuracy of such qualitative analyses. This paper will examine some of the Apparent and Not-So-Apparent Weaknesses associated with expert judgement and how to minimize these weaknesses. Examples related to the development of Documented Safety Analyses will be presented.

Qualitative research creates mountains of words. U.S. federal funding supports mostly structured qualitative research, which is designed to test hypotheses using semi-quantitative coding and analysis. The authors have 30 years of experience in designing and completing major qualitative research projects, mainly funded by the US National Institute on Drug Abuse [NIDA]. This article reports on strategies for planning, organizing, collecting, managing, storing, retrieving, analyzing, and writing about qualitative data so as to most efficiently manage the mountains of words collected in large-scale ethnographic projects. Multiple benefits accrue from this approach. Several different staff members can contribute to the data collection, even when working from remote locations. Field expenditures are linked to units of work so productivity is measured, many staff in various locations have access to use and analyze the data, quantitative data can be derived from data that is primarily qualitative, and improved efficiencies of resources are developed. The major difficulties involve a need for staff who can program and manage large databases, and who can be skillful analysts of both qualitative and quantitative data.

Enhancing the quality and credibility of qualitative analysis.  

PubMed Central

Varying philosophical and theoretical orientations to qualitative inquiry remind us that issues of quality and credibility intersect with audience and intended research purposes. This overview examines ways of enhancing the quality and credibility of qualitative analysis by dealing with three distinct but related inquiry concerns: rigorous techniques and methods for gathering and analyzing qualitative data, including attention to validity, reliability, and triangulation; the credibility, competence, and perceived trustworthiness of the qualitative researcher; and the philosophical beliefs of evaluation users about such paradigm-based preferences as objectivity versus subjectivity, truth versus perspective, and generalizations versus extrapolations. Although this overview examines some general approaches to issues of credibility and data quality in qualitative analysis, it is important to acknowledge that particular philosophical underpinnings, specific paradigms, and special purposes for qualitative inquiry will typically include additional or substitute criteria for assuring and judging quality, validity, and credibility. Moreover, the context for these considerations has evolved. In early literature on evaluation methods the debate between qualitative and quantitative methodologists was often strident. In recent years the debate has softened. A consensus has gradually emerged that the important challenge is to match appropriately the methods to empirical questions and issues, and not to universally advocate any single methodological approach for all problems.

Qualitative and quantitative analysis of probabilistic and deterministic fiber tracking  

NASA Astrophysics Data System (ADS)

Fiber tracking (FT) and quantification algorithms are approximations of reality due to limited spatial resolution, model assumptions, user-defined parameter settings, and physical imaging artifacts resulting from diffusion sequences. Until now, correctness, plausibility, and reliability of both FT and quantification techniques have mainly been verified using histologic knowledge and software or hardware phantoms. Probabilistic FT approaches aim at visualizing the uncertainty present in the data by incorporating models of the acquisition process and noise. The uncertainty is assessed by tracking many possible paths originating from a single seed point, thereby taking the tensor uncertainty into account. Based on the tracked paths, maps of connectivity probabilities can be produced, which may be used to delineate risk structures for presurgical planning. In this paper, we explore the advantages and disadvantages of probabilistic approaches compared to deterministic algorithms and give both qualitative and quantitative comparisons based on clinical data. We focus on two important clinical applications, namely, on the reconstruction of fiber bundles within the proximity of tumors and on the quantitative analysis of diffusion parameters along fiber bundles. Our results show that probabilistic FT is superior and suitable for a better reconstruction at the borders of anatomical structures and is significantly more sensitive than the deterministic approach for quantification purposes. Furthermore, we demonstrate that an alternative tracking approach, called variational noise tracking, is qualitatively comparable with a standard probabilistic method, but is computationally less expensive, thus, enhancing its appeal for clinical applications.

Using qualitative evidence on patients' views to help understand variation in effectiveness of complex interventions: a qualitative comparative analysis  

PubMed Central

Background Complex healthcare interventions consist of multiple components which may vary in trials conducted in different populations and contexts. Pooling evidence from trials in a systematic review is challenging because it is unclear which components are needed for effectiveness. The potential is recognised for using recipients’ views to explore why some complex interventions are effective and others are not. Methods to maximise this potential are poorly developed. Methods We used a novel approach to explore how patients’ views may explain the disparity in effectiveness of complex interventions. We used qualitative comparative analysis to explore agreement between qualitative syntheses of data on patients’ views and evidence from trialed interventions to increase adherence to treatments. We first populated data matrices to reflect whether the content of each trialed intervention could be matched with suggestions arising from patients’ views. We then used qualitative comparative analysis software to identify, by a process of elimination, the smallest number of configurations (patterns) of components that corresponded with patients’ suggestions and accounted for whether each intervention was effective or ineffective. Results We found suggestions by patients were poorly represented in interventions. Qualitative comparative analysis identified particular combinations of components corresponding with patients’ suggestions and with whether an intervention was effective or ineffective. Six patterns were identified for an effective and four for an ineffective intervention. Two types of patterns arose for the effective interventions, one being didactic (providing clear information or instruction) and the other interactive (focusing on personal risk factors). Conclusions Our analysis highlights how data on patients’ views has the potential to identify key components across trials of complex interventions or inform the content of new interventions to be trialed.

Qualitative Measurement of Landscape Structure in an Urbanizing Region: A New Method and Preliminary Results  

NASA Astrophysics Data System (ADS)

Landscape pattern analysis typically involves the mathematical derivation of quantitative metrics from classified rasterized aerial images and/or maps. Recent work by architect Christopher Alexander, however, suggests a new holistic approach to the measurement of landscape structure, based on properties of the relationships between coherent wholes. Measurement of these properties and relationships relies upon qualitative judgment and aesthetic perception, but can be quantified using ordinal scaling and tests of intersubject agreement. I demonstrate how these qualitative pattern measures can be assessed through the use of aerial orthophotographs, and describe preliminary results relating them to an indicator of biodiversity in the urbanizing Pacific Northwest (USA) landscape. I conducted a double-blind survey in which subjects used Alexander's properties to compare aerial photographs of 1 km2 landscapes along an urban to rural gradient in the vicinity of Seattle, Washington. The photographs were of locations with measured avian biodiversity, and represent a range of land-cover types and development patterns. Subjects compared 23 pairs of images, using aesthetic judgement to choose the one in each pair that they felt expresses Alexander's properties to a greater degree. Preliminary results indicate that intersubjective agreement is significantly better than chance for most image pairs (p <= 0.05), and that for most subjects the photographs judged higher in Alexander's properties correspond to the locations with higher bird species richness, at a frequency significantly greater than would be expected by chance (p <= 0.05).

[Qualitative analysis of Raman spectra based on pulse coupled neural network].  

PubMed

By studying on pulse coupled neural network (PCNN) and Raman spectra qualitative analysis, a method based on PCNN for Raman spectra qualitative analysis was proposed. After encoding the Raman spectra by using PCNN neurons' characteristics of fatigue and refractory period, the improved Horspool algorithm was used to match the code corresponding to the detected sample with all of the base code in the database one by one, and then their matching similarity was acquired to determine the sample type. Experimental results and analysis of data proved that the method proposed in this paper is accurate and effective for Raman spectra qualitative analysis. Meanwhile, traditional qualitative analysis method based on spectral template has some deficiencies, like that it is difficult to determine the characteristic peak of the detected sample and the matching analysis process has a high degree of redundancy. While our proposed method not only can avoid these deficiencies very well, but also needs a small amount of data storage. The requirement of the storage space was only 5.8% of that used in the traditional qualitative analysis method based on spectral template. PMID:21105407

To date, no systematic data have been collected on the strategies they use to resolve such difficulties when they do so without the help of ethics consultation. Thus, our understanding of ethical decision making in day to day medical practice is poor. We report findings from the qualitative analysis of 310 ethically difficult situations described to us by physicians who encountered them in their practice. When facing such situations, the physicians sought to avoid conflict, obtain assistance, and protect the integrity of their conscience and reputation, as well as the integrity of the group of people who participated in the decisions. These goals could conflict with each other, or with ethical goals, in problematic ways. Being aware of these potentially conflicting goals may help physicians to resolve ethical difficulties more effectively. This awareness should also contribute to informing the practice of ethics consultation. Objective: To identify strategies used by physicians in dealing with ethical difficulties in their practice. Design, setting, and participants: National survey of internists, oncologists, and intensive care specialists by computer assisted telephone interviews (n = 344, response rate = 64%). As part of this survey, we asked physicians to tell us about a recent ethical dilemma they had encountered in their medical practice. Transcripts of their open-ended responses were analysed using coding and analytical elements of the grounded theory approach. Main measurements: Strategies and approaches reported by respondents as part of their account of a recent ethical difficulty they had encountered in their practice. Results: When faced with ethical difficulties, the physicians avoided conflict and looked for assistance, which contributed to protecting, or attempting to protect, the integrity of their conscience and reputation, as well as the integrity of the group of people who participated in the decisions. These efforts sometimes reinforced ethical goals, such as following patients' wishes or their best interests, but they sometimes competed with them. The goals of avoiding conflict, obtaining assistance, and protecting the respondent's integrity and that of the group of decision makers could also compete with each other. Conclusion: In resolving ethical difficulties in medical practice, internists entertained competing goals that they did not always successfully achieve. Additionally, the means employed were not always the most likely to achieve those aims. Understanding these aspects of ethical decision making in medical practice is important both for physicians themselves as they struggle with ethical difficulties and for the ethics consultants who wish to help them in this process.

Common understandings of women's mental illness in Ghana: results from a qualitative study.  

PubMed

Despite the high rates of depression and anxiety disorders amongst women, the mental health of women is a neglected area, particularly in Africa. This study sought to explore what key stakeholders perceive as the main causes of mental illness in women in Ghana. Using qualitative methods, 81 semi-structured interviews and seven focus group discussions were conducted with 120 key stakeholders drawn from 5 of the 10 regions in Ghana. The analysis was undertaken using a grounded theory approach. Respondents attributed mental illness in women to a number of causes. These included women being the weaker sex, hormones, witchcraft, adultery, abuse and poverty. Explanations could be clustered under three broad categories: women's inherent vulnerability, witchcraft, and gender disadvantage. The way in which women's subordinate position within society may underpin their mental distress needs to be recognized and addressed. The results from this study offer opportunities to identify how policy can better recognize, accommodate and address the mental health needs of women in Ghana and other low-income African countries.

Qualitative and quantitative analysis of DNA fragmentation using digital imaging.  

PubMed

Apoptosis is an important and common pathway of cellular death. Differentiation from cellular necrosis and quantitation of apoptosis within the milieu of necrosis are analytical challenges. We describe the use of the RIT120 digital imaging software package for quantitative and qualitative analysis of apoptotic DNA ladders induced by a variety of agents, such as serum, tumor necrosis factor-alpha, transforming growth factor-beta1, and nitric oxide. Autoradiographs of DNA ladders are densitometrically scanned to yield a set of curves with peaks corresponding to specific DNA fragments, thereby allowing quantitative subtraction of concurrent DNA degradation from necrotic death. Integration of the areas specifically under the peaks yields a quantitative measure of apoptosis. We provide a useful, rapid, and objective means to quantitate apoptosis, using relatively inexpensive hardware and software. PMID:9245431

A Qualitative Analysis of EHR Clinical Document Synthesis by Clinicians  

PubMed Central

Clinicians utilize electronic health record (EHR) systems during time-constrained patient encounters where large amounts of clinical text must be synthesized at the point of care. Qualitative methods may be an effective approach for uncovering cognitive processes associated with the synthesis of clinical documents within EHR systems. We utilized a think-aloud protocol and content analysis with the goal of understanding cognitive processes and barriers involved as medical interns synthesized patient clinical documents in an EHR system to accomplish routine clinical tasks. Overall, interns established correlations of significance and meaning between problem, symptom and treatment concepts to inform hypotheses generation and clinical decision-making. Barriers identified with synthesizing EHR documents include difficulty searching for patient data, poor readability, redundancy, and unfamiliar specialized terms. Our study can inform recommendations for future designs of EHR clinical document user interfaces to aid clinicians in providing improved patient care.

Quantitative end qualitative analysis of the electrical activity of rectus abdominis muscle portions.  

PubMed

The purpose of this study was to investigate the electrical behavior pattern of the Rectus abdominis muscle by qualitative and quantitative analysis of the electromyographic signal obtained from its superior, medium and inferior portions during dynamic and static activities. Ten voluntaries (aged X = 17.8 years, SD = 1.6) athletic males were studied without history of muscle skeletal disfunction. For the quantitative analysis the RMS (Root Mean Square) values obtained in the electromyographic signal during the isometric exercises were normalized and expressed in maximum voluntary isometric contraction percentages. For the qualitative analysis of the dynamic activity the electromyographic signal was processed by full-wave rectification, linear envelope and normalization (amplitude and time), so that the resulting curve of the processed signal was submitted to descriptive graphic analysis. The results of the quantitative study show that there is not a statistically significant difference among the portions of the muscle. Qualitative analysis demonstrated two aspects: the presence of a common activation electric pattern in the portions of Rectus abdominis muscle and the absence of significant difference in the inclination angles in the electrical activity curve during the isotonic exercises.

Calibration transfer based on maximum margin criterion for qualitative analysis using Fourier transform infrared spectroscopy.  

PubMed

A traditional multivariate calibration transfer method such as piecewise direct standardization (PDS) is usually applied to quantitative analysis. To make the method apply to qualitative analysis of Fourier Transform Infrared spectroscopy (FTIR), we propose an improved calibration transfer method based on the maximum margin criterion (CTMMC). The new method not only considers the spectral changes under different conditions, but also takes into account the geometric characteristics of spectra from different classes, so the transformed spectra from different classes will be separated as far as possible, and this will improve the performance of the follow-up qualitative analysis. A comparative study is provided between the proposed method CTMMC and other traditional calibration transfer methods on two data sets. Experimental results show that the proposed method can achieve better performance than previous methods. PMID:23114366

Qualitative analysis in gay men's health research: comparing thematic, critical discourse, and conversation analysis.  

PubMed

Gay men's health typically relies on traditional forms of qualitative analysis, such as thematic analysis, and would benefit from a diversity of analytic approaches. Such diversity offers public health researchers a breadth of tools to address different kinds of research questions and, thus, substantiate different types of social phenomenon relevant to the health and wellbeing of gay men. In this article, I compare and contrast three qualitative analytic approaches: thematic, critical discourse, and conversation analysis. I demonstrate and distinguish their key analytic assumptions by applying each approach to a single data excerpt taken from a public health interview conducted for a broader study on gay men's health. I engage in a discussion of each approach in relation to three themes: its utility for gay men's health, its approach to dilemmas of voice, and its capacity for reflexivity. I advocate that qualitative researchers should capitalise on the full range of qualitative analytic approaches to achieve the goals of gay men's health. However, I specifically encourage qualitative researchers to engage with conversation analysis, not only because of its capacity to resolve dilemmas of voice and to achieve reflexivity, but also for its ability to capture forms of social life hitherto undocumented through thematic and critical discourse analysis.

Bridging the gap between qualitative and quantitative colocalization results in fluorescence microscopy studies  

PubMed Central

Quantitative colocalization studies suffer from the lack of unified approach to interpret obtained results. We developed a tool to characterize the results of colocalization experiments in a way so that they are understandable and comparable both qualitatively and quantitatively. Employing a fuzzy system model and computer simulation, we produced a set of just five linguistic variables tied to the values of popular colocalization coefficients: “Very Weak”, “Weak”, “Moderate”, “Strong”, and “Very Strong”. The use of the variables ensures that the results of colocalization studies are properly reported, easily shared, and universally understood by all researchers working in the field. When new coefficients are introduced, their values can be readily fitted into the set.

Qualitative and quantitative analysis of synapses in Hirschsprung's disease.  

PubMed

In Hirschsprung's disease (HD), certain intestinal nervous plexuses are absent. Sprouting nerve endings contain different amounts of synaptophysin (SY), a protein and main constituent of acetylcholinesterase (AChE) storage compartments. Due to the lack of specific markers for synapses, a qualitative analysis of nerve endings of intestinal segments affected by HD has not yet been undertaken. For this study, resected colorectal specimens from patients with HD (n = 8, mean age 2.1 years) were investigated in parallel for AChE, SY, and content of small synaptic vesicles by biochemical, immunohistochemical, and electronmicroscopic means. In the microdissected muscular layer, reduced SY (1.4 microgram/mg total protein, normal 24 +/- 0.3) was observed. Immunohistochemistry showed in affected tissues reduced numbers of SY-positive nerve fibers and nerve endings, which in turn were thickened and distorted, in both the muscle proper and the muscularis mucosae. Combining both morphologic and biochemical findings, in HD the number of cholinergic vesicles in the remaining nerve endings seems to be increased as measured by SY, a marker molecule specific for synaptic vesicles. Our data also suggest that nerve endings in HD may contain high concentrations of cholinergic vesicles, paralleling the known high amounts of acetylcholine and AChE found in intestinal segments of patients with HD.

Qualitative analysis of mycotoxins using micellar electrokinetic capillary chromatography  

SciTech Connect

Naturally occurring mycotoxins are separated using micellar electrokinetic capillary chromatography. Trends in the retention of these toxins, resulting from changes in mobile-phase composition and pH, are reported and presented as a means of alleviating coelution problems. Two sets of mobile-phase conditions are determined that provide unique separation selectivity. The facile manner by which mobile-phase conditions can be altered, without changes in instrumental configuration, allowed the acquisition of two distinctive, fully resolved chromatograms of 10 mycotoxins in a period of approximately 45 min. By adjusting retention times, using indigenous or added components in mycotoxin samples as normalization standards, it is possible to obtain coefficients of variation in retention time that average less than 1%. The qualitative capabilities of this methodology are evaluated by separating randomly generated mycotoxin-interferent mixtures. In this study, the utilization of normalized retention times applied to separations obtained with two sets of mobile-phase conditions permitted the identification of all the mycotoxins in five unknown samples without any misidentifications. 24 refs., 3 figs., 2 tabs.

Paucity of qualitative research in general medical and health services and policy research journals: analysis of publication rates  

PubMed Central

Background Qualitative research has the potential to inform and improve health care decisions but a study based on one year of publications suggests that it is not published in prominent health care journals. A more detailed, longitudinal analysis of its availability is needed. The purpose of this study was to identify, count and compare the number of qualitative and non-qualitative research studies published in high impact health care journals, and explore trends in these data over the last decade. Methods A bibliometric approach was used to identify and quantify qualitative articles published in 20 top general medical and health services and policy research journals from 1999 to 2008. Eligible journals were selected based on performance in four different ranking systems reported in the 2008 ISI Journal Citation Reports. Qualitative and non-qualitative research published in these journals were identified by searching MEDLINE, and validated by hand-searching tables of contents for four journals. Results The total number of qualitative research articles published during 1999 to 2008 in ten general medical journals ranged from 0 to 41, and in ten health services and policy research journals from 0 to 39. Over this period the percentage of empirical research articles that were qualitative ranged from 0% to 0.6% for the general medical journals, and 0% to 6.4% for the health services and policy research journals. Conclusions This analysis suggests that qualitative research it is rarely published in high impact general medical and health services and policy research journals. The factors that contribute to this persistent marginalization need to be better understood.

Physicians' communicative strategies in interacting with Internet-informed patients: results from a qualitative study.  

PubMed

This article describes the strategies used by physicians to interact with Internet-informed patients, alongside illustrating the motives underlying such strategies. Semistructured interviews were conducted with a sample of 17 physicians from primary care and medical specialist practices in the Italian part of Switzerland. The sample was diversified in terms of specialty, age, and gender. Data collection and analysis were driven by grounded theory and supported by a computer-assisted qualitative analysis program. A typology of four communicative strategies has been outlined. The adoption of these strategies is shaped by physicians' general attitude toward Internet-informed patients, based on their conception of medical information for lay people through the Internet. However, this general attitude is mediated by doctors' interpretation of the specific communicative context, that is, their appraisal of three aspects: the patient's health literacy, the relevance of the online information to be discussed, and their own communicative efficacy. At the end, the process of interpretation underlying the strategies is discussed to expand on it and to identify implications for practice and research. PMID:22260422

The aim of this study is to investigate psychosocial factors related to the diagnosis and treatment of patients with restless legs syndrome. Fifteen patients were interviewed at the Neuro-Sono Outpatient Clinic, Universidade Federal de São Paulo. The results were submitted to a qualitative analysis. We identified four content categories: illness description, illness history, illness experience, and relationships. Lack of control over the body and lack of recognition by professionals produce stigma and lead patients to suffering. The research underscores the relevance of psychosocial factors to the diagnosis and treatment of patients with restless legs syndrome and the importance of having interdisciplinary teams when attending patients with restless legs syndrome.

Factors Affecting Antenatal Care Attendance: Results from Qualitative Studies in Ghana, Kenya and Malawi  

PubMed Central

Background Antenatal care (ANC) is a key strategy to improve maternal and infant health. However, survey data from sub-Saharan Africa indicate that women often only initiate ANC after the first trimester and do not achieve the recommended number of ANC visits. Drawing on qualitative data, this article comparatively explores the factors that influence ANC attendance across four sub-Saharan African sites in three countries (Ghana, Kenya and Malawi) with varying levels of ANC attendance. Methods Data were collected as part of a programme of qualitative research investigating the social and cultural context of malaria in pregnancy. A range of methods was employed interviews, focus groups with diverse respondents and observations in local communities and health facilities. Results Across the sites, women attended ANC at least once. However, their descriptions of ANC were often vague. General ideas about pregnancy care – checking the foetus’ position or monitoring its progress – motivated women to attend ANC; as did, especially in Kenya, obtaining the ANC card to avoid reprimands from health workers. Women’s timing of ANC initiation was influenced by reproductive concerns and pregnancy uncertainties, particularly during the first trimester, and how ANC services responded to this uncertainty; age, parity and the associated implications for pregnancy disclosure; interactions with healthcare workers, particularly messages about timing of ANC; and the cost of ANC, including charges levied for ANC procedures – in spite of policies of free ANC – combined with ideas about the compulsory nature of follow-up appointments. Conclusion In these socially and culturally diverse sites, the findings suggest that ‘supply’ side factors have an important influence on ANC attendance: the design of ANC and particularly how ANC deals with the needs and concerns of women during the first trimester has implications for timing of initiation.

Qualitative and quantitative analysis of volatile constituents from latrines.  

PubMed

More than 2.5 billion people defecate in the open. The increased commitment of private and public organizations to improving this situation is driving the research and development of new technologies for toilets and latrines. Although key technical aspects are considered by researchers when designing new technologies for developing countries, the basic aspect of offending malodors from human waste is often neglected. With the objective of contributing to technical solutions that are acceptable to global consumers, we investigated the chemical composition of latrine malodors sampled in Africa and India. Field latrines in four countries were evaluated olfactively and the odors qualitatively and quantitatively characterized with three analytical techniques. Sulfur compounds including H2S, methyl mercaptan, and dimethyl-mono-(di;tri) sulfide are important in sewage-like odors of pit latrines under anaerobic conditions. Under aerobic conditions, in Nairobi for example, paracresol and indole reached concentrations of 89 and 65 ?g/g, respectively, which, along with short chain fatty acids such as butyric acid (13 mg/g) explained the strong rancid, manure and farm yard odor. This work represents the first qualitative and quantitative study of volatile compounds sampled from seven pit latrines in a variety of geographic, technical, and economic contexts in addition to three single stools from India and a pit latrine model system.

Exploring spirituality in Iranian healthy elderly people: A qualitative content analysis  

PubMed Central

Background: Spirituality is recognized as a personally important matter to the elderly, and there are evidences of its impact on their health. The aim of this study was to explore the concept of spirituality from the perspectives of Iranian healthy elderly individuals. Materials and Methods: A conventional qualitative content analysis of carried out with 21 healthy elderly people from both male and female genders were chosen using a purposive sampling method in Tehran in 2010-2011. Data collection was done through semi structured interviews. A qualitative content analysis was used to analyze the participants’ experiences and perceptions on spirituality, using a central question ‘what characterizes the spirituality in the Iranian healthy elderly people?’ Results: The following categories emerged from the data analysis: (1) Spiritual health, with four sub categories including saying prayer as a calming factor; beneficence as a way to God; loss of psychological and spiritual support; faith as a way to happiness; (2) spiritual beliefs, with three sub categories including seeking help from God in difficulties; God's power over life and death; doing good deeds is the God's will; and (3) religious practice with three sub categories including saying prayer; reading Quran; and going to mosque, religious ceremonies and pilgrimage. Conclusions: In this study was found that spirituality was a fundamental element in elderly individuals’ lives that help them to adapt with daily living conditions.

Twenty-Year Survey of Scientific Literacy and Attitudes Toward Science_Qualitative Analysis  

NASA Astrophysics Data System (ADS)

This poster presents findings from the qualitative analysis of data from a long-term investigation into the science literacy and attitudes toward science of University of Arizona non-science major undergraduates (see Impey et al., this meeting). The qualitative analysis centered on student responses to four open-ended questions probing science process and content knowledge, derived from measures of adults’ science literacy as defined and assessed by the National Science Foundation in its biannual Science and Engineering Indicators reports to the National Science Board. The four questions asked students to briefly describe (1) DNA; (2) radiation; (3) software; and (4) the nature of scientific study. Data was coded thematically both for students’ depth of understanding of each concept as well as for common and uncommon beliefs and reasoning difficulties. Analysis included investigations into changes in students’ understandings of the different concepts over time. The data suggest trends in students’ conceptions and influences on those conceptions. In addition, the results of this study are being used to develop a survey instrument designed specifically for use with Astro 101 students to evaluate the effectiveness of instruction on their scientific attitudes and beliefs as a Collaboration of Astronomy Teaching Scholars (CATS) research project. We acknowledge the NSF for funding under Award No. 0715517, a CCLI Phase III Grant for the Collaboration of Astronomy Teaching Scholars (CATS).

Simulations and qualitative analysis of the AMPTE experiments  

SciTech Connect

This paper summarizes simulations and qualitative analyses of artificial plasma releases into the solar wind done as part of the AMPTE experimental program. Lithium and barium were released during different parts of this program. Observations were made both by instrumentation on the satellites doing the releases, as well as from ground based instruments. The satellites observed particle energies, as well as energetic electrons. They also made wave measurements of phenomena within and in front of the expanding cloud. The clouds were observed from the ground to sense their motion, growth, and topological changes. Following the release of experimental information from these tests, there has been an extensive effort to model the observations, and thereby shed light on the physics hidden in these observations. They provide a glimpse of the time development of auroral phenomena in a controlled manner.

Quantitative and qualitative analysis of rhinovirus infection in bronchial tissues.  

PubMed

Although rhinovirus (RV) infections can cause asthma exacerbations and alter lower airway inflammation and physiology, it is unclear how important bronchial infection is to these processes. To study the kinetics, location, and frequency of RV appearance in lower airway tissues during an acute infection, immunohistochemistry and quantitative polymerase chain reaction analysis were used to analyze the presence of virus in cells from nasal lavage, sputum, bronchoalveolar lavage, bronchial brushings, and biopsy specimens from 19 subjects with an experimental RV serotype 16 (RV16) cold. RV was detected by polymerase chain reaction analysis on cells from nasal lavage and induced sputum samples from all subjects after RV16 inoculation, as well as in 5 of 19 bronchoalveolar lavage cell samples and in 5 of 18 bronchial biopsy specimens taken 4 days after virus inoculation. Immunohistochemistry detected RV16 in 39 and 36% of all biopsy and brushing samples taken 4 and 15 days, respectively, after inoculation. Infected cells were primarily distributed in discrete patches on the epithelium. These results confirm that infection of lower airway tissues is a frequent finding during a cold and further demonstrate a patchy distribution of infected cells, a pattern similar to that reported in upper airway tissues.

Qualitative Analysis of an Educational Intervention with HIV-Discordant Heterosexual Latino Couples  

PubMed Central

Objective This qualitative analysis elucidates the potential elements of the intervention that may be effective in terms of a) increasing knowledge about HIV/AIDS in the members of this population; b) increasing the use of male condoms and the practice of mutual masturbation; and c) changing opinions toward male condom use and mutual masturbation. Methods Five heterosexual HIV-discordant couples participated in the adapted intervention, which consisted of four three-hour-long sessions. One month after the intervention, we conducted a qualitative semi-structured interview with every participant to evaluate issues related to the process and content of the activities comprising the intervention, the impact of the intervention, logistics, and recruitment and retention as well as to make a more general evaluation. The information was submitted to qualitative content analysis. Results After the intervention, participants reported having better attitudes regarding safer sex, particularly in terms of condom use. A reason given by the participants to feel more positive toward condom use and mutual masturbation was that these practices could prevent the infection of the HIV-negative partner. Conclusion This study provides important evidence of an intervention that promises to be efficacious in preventing some high-risk sexual behaviors among Latino HIV-discordant heterosexual couples. The evidence presented seems to suggest that an intervention that includes basic relevant information about HIV/AIDS, that explains the benefits of condom use and other safer sex options, and that provides effective negotiation and communication strategies could significantly reduce HIV transmission among these couples.

Qualitative environmental analysis for industrial districts implantation using geoprocessing techniques.  

PubMed

Industrial districts became important instruments which are used by the Public Power to induce economic decentralization and create new development poles. For this reason the legislative process is an indispensable means to define the priorities in the uses of soil, also to conduct and follow the process of industrial registration. However, the industrial district establishment shall not be analyzed by taking into account just the economic factor, but also the environmental issue of the enterprise. Thus, this research has the objective of determining adequate places for industrial districts implantation, having as a pilot area the city of São Leopoldo, Rio Grande do Sul State, Brazil. A Geographic Information System for execution of spatial analysis and criteria creation on a large volume of environmental information will be used as a tool, which will be guided by the Municipal, State and Federal legislation and a Quickbird satellite image that covers the interest area. The main information used on this research are: altimeter, hydrography, soil use, pedology, geology and infrastructure. The results are visualized in scenarios modeled in accordance with the restrictions imposed upon the information, allowing at the end, to combine all scenarios and create through the multiple criteria method a map that indicates adequate places for implantation of industrial districts.

Geysers of Enceladus: Quantitative analysis of qualitative models  

NASA Astrophysics Data System (ADS)

Aspects of two qualitative models of Enceladus’ dust plume—the so-called “Cold Faithful” [Porco, C.C., et al., 2006. Cassini observes the active south pole of Enceladus. Science 311, 1393 1401; Ingersoll, A.P., et al., 2006. Models of the Enceladus plumes. In: Bulletin of the American Astronomical Society, vol. 38, p. 508] and “Frigid Faithful” [Kieffer, S.W., et al., 2006. A clathrate reservoir hypothesis for Enceladus’ south polar plume. Science 314, 1764; Gioia, G., et al., 2007. Unified model of tectonics and heat transport in a Frigid Enceladus. Proc. Natl. Acad. Sci. 104, 13578 13591] models—are analyzed quantitatively. The former model assumes an explosive boiling of subsurface liquid water, when pressure exerted by the ice crust is suddenly released due to an opening crack. In the latter model the existence of a deep shell of clathrates below Enceladus’ south pole is conjectured; clathrates can decompose explosively when exposed to vacuum through a fracture in the outer icy shell. For the Cold Faithful model we estimate the maximal velocity of ice grains, originating from water splashing in explosive boiling. We find that for water near the triple point this velocity is far too small to explain the observed plume properties. For the Frigid Faithful model we consider the problem of momentum transfer from gas to ice particles. It arises since any change in the direction of the gas flow in the cracks of the shell requires re-acceleration of the entrained grains. While this effect may explain the observed speed difference of gas and grains if the gas evaporates from triple point temperature (273.15 K) [Schmidt, J., et al., 2008. Formation of Enceladus dust plume. Nature 451, 685], the low temperatures of the Frigid Faithful model (˜140 170K) imply a too dilute vapor to support the observed high particle fluxes in Enceladus’ plume.

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.

Software Safety Analysis of Digital Protection System Requirements Using a Qualitative Formal Method  

SciTech Connect

The safety analysis of requirements is a key problem area in the development of software for the digital protection systems of a nuclear power plant. When specifying requirements for software of the digital protection systems and conducting safety analysis, engineers find that requirements are often known only in qualitative terms and that existing fault-tree analysis techniques provide little guidance on formulating and evaluating potential failure modes. A framework for the requirements engineering process is proposed that consists of a qualitative method for requirements specification, called the qualitative formal method (QFM), and a safety analysis method for the requirements based on causality information, called the causal requirements safety analysis (CRSA). CRSA is a technique that qualitatively evaluates causal relationships between software faults and physical hazards. This technique, extending the qualitative formal method process and utilizing information captured in the state trajectory, provides specific guidelines on how to identify failure modes and the relationship among them. The QFM and CRSA processes are described using shutdown system 2 of the Wolsong nuclear power plants as the digital protection system example.

"What is Found There"1: Qualitative Analysis of Physician-Nurse Collaboration Stories  

PubMed Central

Background Effective physician–nurse collaboration is an important, but incompletely understood determinant of patient and nurse satisfaction, and patient safety. Its impact on physicians has not been described. This study was undertaken to develop a fuller understanding of the collaboration experience and its outcomes. Methods Twenty-five medical residents, 32 staff nurses, 5 physician and 5 nurse faculty wrote narratives about successful collaboration; the narratives were then qualitatively analyzed. Narrative analysis was the initial qualitative method iteratively employed to identfy themes. A phenomenological approach was subsequently used to develop a framework for collaborative competence. Results Collaboration triggers, facilitative behaviors, outcomes and collaborative competence were the themes identified. Affect was identified in the triggers leading to collaboration and in its outcomes. Practioners typically entered a care episode feeling worrried, uncertain or inadequate and finished the interaction feeling satisfied, understood and grateful to their colleagues. The frequency of affective experience was not altered by gender, profession, or ethnicity. These experiences were particularly powerful for novice practioners of both disciplines and appear to have both formative and transformative potential. Collaborative competence was characterized by a series of graduated skills in clinical and relational domains. Many stories took place in the ICU and afterhours settings. Conclusions Despite the prevailing wisdom that nursing and medicine are qualitatively different, the stories from this study illuminate surprising commonalities in the collaboration experience, regardless of gender, age, experience, or profession. Collaborative competence can be defined and its component skills identified. Contexts of care can be identified that offer particularly rich opportunities to foster interprofessional collaboration.

The aims of this paper are as follows: to analyse any possible implications of family organisation in the health practices of the immigrant population; to ascertain social practices relating to illness; to understand the significances of sexual and reproductive health practices; and to ascertain the ideas and perceptions of immigrants, local people and professionals regarding health and the health system. Methods Qualitative research based on discursive analysis. Data gathering techniques consisted of discussion groups with health system users and semi-structured individual interviews with healthcare professionals. The sample was taken from the Basic Healthcare Areas of Salt and Banyoles (belonging to the Girona Healthcare Region), the discussion groups being comprised of (a) 6 immigrant Moroccan women, (b) 7 immigrant sub-Saharan African women and (c) 6 immigrant and native population men (2 native men, 2 Moroccan men and 2 sub-Saharan men); and the semi-structured interviews being conducted with the following healthcare professionals: (a) 3 gynaecologists, (b) 3 nurses and 1 administrative staff. Results Use of the healthcare system is linked to the perception of not being well, knowledge of the healthcare system, length of time resident in Spain and interiorization of traditional Western medicine as a cure mechanism. The divergences found among the groups of immigrants, local people and healthcare professionals with regard to healthcare education, use of the healthcare service, sexual and reproductive healthcare and reticence with regard to being attended by healthcare personnel of the opposite sex demonstrate a need to work with the immigrant population as a heterogeneous group. Conclusions The results we have obtained support the idea that feeling unwell is a psycho-social process, as it takes place within a specific socio-cultural situation and spans a range of beliefs, perceptions and ideas regarding symptomology and how to treat it.

Female adolescents' experiences and perceptions regarding sexual health education in Iranian schools: A qualitative content analysis  

PubMed Central

Background: Despite so many unmet sexual health education (SHE) needs of adolescents, socio-cultural challenges have caused this issue to be ignored in different scoieties. This study investigated Iranian female adolescents’ experiences and perceptions with respect to SHE that they received at schools, and what they really needed, expected, and preferred. Materials and Methods: In this qualitative study, seven focus group discussions (44 adolescents) and 13 individual in-depth interviews were conducted among female adolescents aged 14-18 in Mashhad and Ahvaz, Iran, to explore adolescents’ experiences and perceptions towards SHE in Iranian schools. Data were analyzed using qualitative content analysis. Results: Analyzing adolescents’ perspectives and experiences revealed their great dissatisfaction with SHE in schools. Emerged categories included: lack of obligation and priority for SHE, sexual reticence and evading, making adolescents frightened of sexual issues, inconsistency of SHE with adolescents’ needs, unqualified educators, and lack of appropriate educational materials. Conclusion: This study found some similarities between expectations of Iranian adolescents and those of adolescents from other cultures about an SHE program. Adolescents showed great abilities to appraise health services delivered for them, and so any program for sexual health promotion in adolescents ought to address adolescents’ needs, demands, and aspirations. Their contribution can provide insights for tailoring SHE programs for adolescents.

A new method for robust quantitative and qualitative analysis of real-time PCR.  

PubMed

An automated data analysis method for real-time PCR needs to exhibit robustness to the factors that routinely impact the measurement and analysis of real-time PCR data. Robust analysis is paramount to providing the same interpretation for results regardless of the skill of the operator performing or reviewing the work. We present a new method for analysis of real-time PCR data, the maxRatio method, which identifies a consistent point within or very near the exponential region of the PCR signal without requiring user intervention. Compared to other analytical techniques that generate only a cycle number, maxRatio generates several measurements of amplification including cycle numbers and relative measures of amplification efficiency and curve shape. By using these values, the maxRatio method can make highly reliable reactive/nonreactive determination along with quantitative evaluation. Application of the maxRatio method to the analysis of quantitative and qualitative real-time PCR assays is shown along with examples of method robustness to, and detection of, amplification response anomalies.

Qualitative analysis of systems with an ideal boundary constraint  

NASA Astrophysics Data System (ADS)

The use of Hamiltonian equations of motion for systems with an ideal boundary constraint is discussed with particular reference to difficulties associated with the nonanaliticity of the Hamiltonian function. In particular, an algorithm is proposed whereby classical mechanics and Poincare's theory of periodic motions can be used for the analysis of systems with a Hamiltonian that is nonanalytic with respect to one phase variable. The dynamics of a rigid body colliding with an absolutely smooth stationary horizontal plane is examined as an example.

Thematic Analysis of Iranian Female Adolescents' Perceptions About HIV/AIDS: A Qualitative Study  

PubMed Central

Background: HIV/AIDS continues to be a major global health problem. The aim of this study was to evaluate common opinions and beliefs about HIV/AIDS among Iranian teenager girls. Methods: This Qualitative study (face-to-face interviews with tape recording) was conducted among fifty female teenager school students in Urmia-Iran. Results: The thematic analysis indicated the main information sources for HIV/AIDS among teenage girls to be their mother and teachers. The participants had little concern about the dissemination of HIV/AIDS in Iran. Using a common syringe is mentioned as the main risk factor for HIV transmission. There were some misconceptions about the at-risk group among teenage girls. Conclusions: Considering the misconceptions among the teenage girls, their beliefs should be reformed and reorganized in order to reduce the risk of exposure to HIV. The best practice is training life skills in the school level.

Voices of the self in psychotherapy: a qualitative analysis.  

PubMed

Approaches that view the self as constituted by socio-cultural processes and as plural, consisting of a multiplicity of states, positions, functions, etc., have flourished in the last decades. This paper explores the multi-voiced nature of the self, drawing upon Lacan's theory of subjectivity and Bakhtin's concept of dialogism. Subjectivity is seen as constituted through language as expressed in the speech of the subject's important early others. The psychoanalytic concept of transference, understood as a semiotic process of enacting early interpersonal patterns in the subject's present relations, provides a link between the unfolding of subjectivity in the present and its historical continuity. The articulation of subjectivity is discussed through a micro-analysis of extracts from sessions of a long-term psychoanalytic psychotherapy. The analysis demonstrates the enactment of transferential dialogical positions at the beginning of the therapy and traces their recognition by the client through the gradual development of increasingly reflexive subject positions towards the end of therapy. It is argued that the aim of therapy should be the facilitation of a complex subjectivity, whereby the different subject positions can be fluently articulated within an overall reflexive frame.

Maritime shipping as a high reliability industry: A qualitative analysis  

SciTech Connect

The maritime oil shipping industry has great public demands for safe and reliable organizational performance. Researchers have identified a set of organizations and industries that operate at extremely high levels of reliability, and have labelled them High Reliability Organizations (HRO). Following the Exxon Valdez oil spill disaster of 1989, public demands for HRO-level operations were placed on the oil industry. It will be demonstrated that, despite enormous improvements in safety and reliability, maritime shipping is not operating as an HRO industry. An analysis of the organizational, environmental, and cultural history of the oil industry will help to provide justification and explanation. The oil industry will be contrasted with other HRO industries and the differences will inform the shortfalls maritime shipping experiences with regard to maximizing reliability. Finally, possible solutions for the achievement of HRO status will be offered.

Qualitative analysis of algal secretions with multiple mass spectrometric platforms.  

PubMed

Lipid secretions from algae pose a great opportunity for engineering biofueler feedstocks. The lipid exudates could be interesting from a process engineering perspective because lipids could be collected directly from the medium without harvesting and disrupting cells. We here report on the extracellular secretions of algal metabolites from the strain UTEX 2341 (Chlorella minutissima) into the culture medium. No detailed analysis of these lipid secretions has been performed to date. Using multiple mass spectrometric platforms, we observed around 1000 compounds and were able to annotate 50 lipids by means of liquid chromatography coupled to accurate mass quadrupole time-of-flight mass spectrometry (LC-QTOF), direct infusion with positive and negative electrospray ion trap mass spectrometry and gas chromatography coupled to mass spectrometry (GC-MS). These compounds were annotated by tandem mass spectral (MS/MS) database matching and retention time range filtering. We observed a series of triacylglycerols (TG), sulfoquinovosyldiacylglycerols (SQDG), phosphatidylinositols and phosphatidylglycerols, as well as betaine lipids diacylglyceryl-N,N,N-trimethylhomoserines (DGTS).

Using multiple PCR and CE with chemiluminescence detection for simultaneous qualitative and quantitative analysis of genetically modified organism.  

PubMed

In this paper, an ultrasensitive CE-CL detection system coupled with a novel double-on-column coaxial flow detection interface was developed for the detection of PCR products. A reliable procedure based on this system had been demonstrated for qualitative and quantitative analysis of genetically modified organism-the detection of Roundup Ready Soy (RRS) samples was presented as an example. The promoter, terminator, function and two reference genes of RRS were amplified with multiplex PCR simultaneously. After that, the multiplex PCR products were labeled with acridinium ester at the 5'-terminal through an amino modification and then analyzed by the proposed CE-CL system. Reproducibility of analysis times and peak heights for the CE-CL analysis were determined to be better than 0.91 and 3.07% (RSD, n=15), respectively, for three consecutive days. It was shown that this method could accurately and qualitatively detect RRS standards and the simulative samples. The evaluation in terms of quantitative analysis of RRS provided by this new method was confirmed by comparing our assay results with those of the standard real-time quantitative PCR (RT-QPCR) using SYBR Green I dyes. The results showed a good coherence between the two methods. This approach demonstrated the possibility for accurate qualitative and quantitative detection of GM plants in a single run.

Suggestions for preparing itinerant teachers: a qualitative analysis.  

PubMed

Increasing numbers of students who are deaf or hard of hearing receive educational services in general education classrooms. This placement shift has altered the way teachers of students who are deaf or hard of hearing work, causing an increase in the number of itinerant teachers. As placement trends for students who are deaf or hard of hearing and teachers' job responsibilities have changed, the field of deaf education has only slightly modified professional standards for licensed teachers of students who are deaf or hard of hearing. Most teacher preparation programs continue training preservice teachers to work in self-contained classrooms, leaving itinerant teachers feeling underprepared. Interviews were conducted with 25 experienced itinerant teachers to determine which content and experiences should be included in preparation programs for preservice teachers of students who are deaf or hard of hearing who plan to become itinerant teachers. Results indicate that changes in course work and practical are necessary to best prepare these teachers. PMID:12448133

Quantitative and qualitative analysis of urine component in the toilet set using Raman spectroscopy  

NASA Astrophysics Data System (ADS)

As a part of non-invasive and unaware measurement of physiological signal in the house of live-alone person, Raman spectroscopy was applied for urine component analysis in the toilet set. 785nm, 250-300mW output solid state diode laser and 2048 element linear silicon TE cooled CCD array were incorporated for this system. Several tests were performed for setting up Raman spectroscopy in non-constrained situation: toilet set in the house. The effect of dark current, integration time, warming up time of laser, property of probe and interference of water in the toilet were tested and controlled for appropriate measurement in this environment. The spectra were obtained immediately when the subject uses the toilet set, and they can be transmitted to the server though Bluetooth. Those spectra were pre-processed for removing or correcting the effect of undesired light scattering, sample path-length difference and baseline-effect. The preprocessed data were enhanced for more exact result of multivariate analysis. The training data was prepared for predicting unknown component and its concentration by using multivariate methods. Several kinds of multivariate methods: PCA, PCR, PLS were performed to validate what is the fittest method in this environment. Through quantitative and qualitative analysis of Raman spectroscopy"s spectra obtained in the house's toilet set, we could know the component and its concentration of urine which can be index of disease.

Background Spirituality is a subjective and multi-dimensional concept. The ambiguity in its meaning can create barriers in its application in both education and medicine. The present study aimed to explore the Iranian cancer patients’ perception of spirituality. Methods A qualitative study, using the content analysis approach, was conducted. Semi-structured interviews were held with 11 cancer patients and six members of their families in one of Tehran’s hospitals and a charity institute. The data generated were transcribed verbatim and content analysis approach was used for data reduction, naming data, obtaining analytical code and determining categories and themes. Results Three themes (and seven sub-themes) emerged from the data analysis: 1) God as the spiritual truth (relationship with God and trust in God), 2) Moralities as a spiritual sign (considering personal and social moral codes) and 3) Spiritual resources as the source of hope (religious, personal and social resources). Conclusions Overall, in the view of cancer patients, spirituality can be defined in a religious context. However, some of them believe in morality beside religiosity, so health care staff must pay due attention to these aspects, to provide them with the opportunity to use spiritual resources.

Consumer perceptions of beef healthiness: results from a qualitative study in four European countries  

PubMed Central

Background Consumer perception of the healthiness of beef is an important determinant of beef consumption. However, little is known about how consumers perceive the healthiness of beef. The aim of this study is to shed light on the associations between beef and health. Methods Eight focus group discussions were conducted in four European countries (France, UK, Germany, Spain), each consisting of seven to nine participants. A content analysis was performed on the transcripts of these discussions. Results Although beef was generally perceived as healthful, focus group participants expected positive as well as negative effects of beef consumption on their health. Labelled, branded, fresh and lean beef were perceived as signalling healthful beef, in contrast with further processed and packaged beef. Consumers felt that their individual choices could make a difference with respect to the healthiness of beef consumed. Focus group participants were not in favour of improving beef healthiness during processing, but rather focussed on appropriate consumption behaviour and preparation methods. Conclusions The individual responsibility for health implies that consumers should be able to make correct judgements about how healthful their food is. However, the results of this study indicate that an accurate assessment of beef healthiness is not always straightforward. The presented results on consumer perceptions of beef healthiness provide insights into consumer decision making processes, which are important for the innovation and product differentiation in the European beef sector, as well as for public health policy decisions related to meat consumption in general and beef consumption in particular.

Researchers' perceptions of ethical challenges in cluster randomized trials: a qualitative analysis  

PubMed Central

Background Cluster randomized trials (CRTs) pose ethical challenges for investigators and ethics committees. This study describes the views and experiences of CRT researchers with respect to: (1) ethical challenges in CRTs; (2) the ethics review process for CRTs; and (3) the need for comprehensive ethics guidelines for CRTs. Methods Descriptive qualitative analysis of interviews conducted with a purposive sample of 20 experienced CRT researchers. Results Informants expressed concern over the potential for bias that may result from requirements to obtain informed consent from research participants in CRTs. Informants suggested that the need for informed consent ought to be related to the type of intervention under study in a CRT. Informants rarely expressed concern regarding risks to research participants in CRTs, other than risks to privacy. Important issues identified in the research ethics literature, including fair subject selection and other justice issues, were not mentioned by informants. The ethics review process has had positive and negative impacts on CRT conduct. Informants stated that variability in ethics review between jurisdictions, and increasingly stringent ethics review in recent years, have hampered their ability to conduct CRTs. Many informants said that comprehensive ethics guidelines for CRTs would be helpful to researchers and research ethics committees. Conclusions Informants identified key ethical challenges in the conduct of CRTs, specifically relating to identifying subjects, seeking informed consent, and the use of gatekeepers. These data have since been used to identify topics for in-depth ethical analysis and to guide the development of comprehensive ethics guidelines for CRTs.

Qualitative femur bone tensile strength analysis in radiographic images using wavelets - biomed 2011.  

PubMed

In this work, the tensile strength of femur bone is qualitatively analyzed using radiographic images. The sub anatomic tensile regions were delineated from conventional planar radiographic femur images using digital image processing algorithms. The normal and abnormal images are then subjected to Daubechies5, coiflet5 and Haar wavelets decomposed at three levels to derive approximation and detail coefficients. The qualitative analyses were also performed on the delineated images to derive apparent mineralization and total area. The values of higher order energy parameter are derived for both approximation and detail coefficients in each level of decomposition and are correlated with apparent mineralization for analysis. Results show that the low values of energy correlates well with abnormalities in all levels of decomposition for all the three wavelets. Among all, the values of energy derived out of approximation coefficient using Haar wavelets show higher degrees of correlations in both primary tensile and secondary tensile regional strength. The variations between normal and abnormal were also found to be statistically significant. Poor correlation was observed in the case of detailed coefficients for all the wavelets irrespective of levels. Among all wavelets, the parameters decomposed at level one approximation coefficient of Haar wavelet appear to be a useful predictor for classifying normal and abnormal samples. This could be attributed to sensitivity of adopted wavelets to the architectural changes and discontinuities in regional distribution of trabecular pattern in tensile region. It appears that this methodology could be used for gross abnormality detection, micro-damage studies and modeling the mechanics of soft tissue in diseases. Thus wavelet extracted feature on tensile trabeculae regions of radiographic femur images could be a used as an index for automated screening of bone strength. PMID:21525609

Simple optical method of qualitative assessment of sperm motility: preliminary results  

NASA Astrophysics Data System (ADS)

The examination of quality of the sperm ejaculate is one of the most important steps in artificial fertilization procedure. The main aim of semen storage centres is to characterise the best semen quality for fertilization. Reliable information about sperm motility is also one the most important parameters for in vitro laboratory procedures. There exist very expensive automated methods for semen analysis but they are unachievable for most of laboratories and semen storage centres. Motivation for this study is to elaborate a simple, cheap, objective and repeatable method for semen motility assessment. The method enables to detect even small changes in motility introduced by medical, physical or chemical factors. To test the reliability of the method we used cryopreserved bull semen from Lowicz Semen Storage Centre. The examined sperm specimen was warmed in water bath and then centrifuged. The best semen was collected by the swim-up technique and diluted to a proper concentration. Several semen concentrations and dilutions were tested in order to find the best probe parameters giving repeatable results. For semen visualization we used the phase-contrast microscope with a CCD camera. A PC computer was used to acquire and to analyse the data. The microscope table equipped with a microscope glass pool 0.7mm deep instead of some conventional plane microscope slides was stabilised at the temperature of 37°C. The main idea of our method is based on a numerical processing of the optical contrast of the sperm images which illustrates the dynamics of the sperm cells movement and on appropriate analysis of a grey scale level of the superimposed images. An elaborated numerical algorithm allows us to find the relative amount of motile sperm cells. The proposed method of sperm motility assessment seems to be objective and repeatable.

Race and Older Mothers' Differentiation: A Sequential Quantitative and Qualitative Analysis  

PubMed Central

The goal of this paper is to demonstrate a process by which qualitative and quantitative approaches are combined to reveal patterns in the data that are unlikely to be detected and confirmed by either method alone. Specifically, we take a sequential approach to combining qualitative and quantitative data to explore race differences in how mothers differentiate among their adult children. We began with a standard multivariate analysis examining race differences in mothers’ differentiation among their adult children regarding emotional closeness and confiding. Finding no race differences in this analysis, we conducted an in-depth comparison of the Black and White mothers’ narratives to determine whether there were underlying patterns that we had been unable to detect in our first analysis. Using this method, we found that Black mothers were substantially more likely than White mothers to emphasize interpersonal relationships within the family when describing differences among their children. In our final step, we developed a measure of familism based on the qualitative data and conducted a multivariate analysis to confirm the patterns revealed by the in-depth comparison of the mother’s narratives. We conclude that using such a sequential mixed methods approach to data analysis has the potential to shed new light on complex family relations.

Assessing parameter importance of the Common Land Model based on qualitative and quantitative sensitivity analysis  

NASA Astrophysics Data System (ADS)

Proper specification of model parameters is critical to the performance of land surface models (LSMs). Due to high dimensionality and parameter interaction, estimating parameters of an LSM is a challenging task. Sensitivity analysis (SA) is a tool that can screen out the most influential parameters on model outputs. In this study, we conducted parameter screening for six output fluxes for the Common Land Model: sensible heat, latent heat, upward longwave radiation, net radiation, soil temperature and soil moisture. A total of 40 adjustable parameters were considered. Five qualitative SA methods, including local, sum-of-trees, multivariate adaptive regression splines, delta test and Morris methods, were compared. The proper sampling design and sufficient sample size necessary to effectively screen out the sensitive parameters were examined. We found that there are 2-8 sensitive parameters, depending on the output type, and about 400 samples are adequate to reliably identify the most sensitive parameters. We also employed a revised Sobol' sensitivity method to quantify the importance of all parameters. The total effects of the parameters were used to assess the contribution of each parameter to the total variances of the model outputs. The results confirmed that global SA methods can generally identify the most sensitive parameters effectively, while local SA methods result in type I errors (i.e., sensitive parameters labeled as insensitive) or type II errors (i.e., insensitive parameters labeled as sensitive). Finally, we evaluated and confirmed the screening results for their consistency with the physical interpretation of the model parameters.

Shifted Excitation Raman Difference Spectroscopy (SERDS) implemented with two wavelength-stabilized laser diodes with fixed wavelength separation is discussed as an effective method for dealing with the effects of fluorescence in Raman spectroscopic analysis. In this presentation we discuss the results of both qualitative and quantitative SERDS analysis of a variety of strongly fluorescing samples, including binary liquid mixtures. This application is enabled by the Volume Bragg Grating® (VBG®) technology, which allows manufacturing of compact low-cost high-power laser sources, suitable for extending the SERDS methodology to portable Raman spectrometers.

A Qualitative Analysis of Health Literacy Issues among Women with Visual Impairments  

PubMed Central

The purpose of this secondary analysis using qualitative description was to explore health literacy from the healthcare experiences of women with permanent visual impairments. Interviews from a sample of 15 community-residing women age 44 to 79 years with permanent visual impairments who had participated in a larger grounded theory study were analyzed. The 15 women were interviewed twice, with each interview lasting up to three hours. The audio-taped interviews were transcribed verbatim and analyzed using qualitative content analysis. Using the Institute of Medicine’s definition of health literacy, the women’s experiences were categorized into their ability to obtain, process, and understand health information. Their perceptions of the factors that influenced their health literacy were also explored. The women voiced that barriers to their ability to gain information in a format amenable to their processing skills, combined with barriers arising from healthcare providers’ attitudes, undermined their ability to build health literacy capacity.

Qualitative analysis using Raman spectroscopy and chemometrics: a comprehensive model system for narcotics analysis.  

PubMed

The rapid, on-site identification of illicit narcotics, such as cocaine, is hindered by the diverse nature of the samples, which can contain a large variety of materials in a wide concentration range. This sample variance has a very strong influence on the analytical methodologies that can be utilized and in general prevents the widespread use of quantitative analysis of illicit narcotics on a routine basis. Raman spectroscopy, coupled with chemometric methods, can be used for in situ qualitative and quantitative analysis of illicit narcotics; however, careful consideration must be given to dealing with the extensive variety of sample types. To assess the efficacy of combining Raman spectroscopy and chemometrics for the identification of a target analyte under real-world conditions, a large-scale model sample system (633 samples) using a target (acetaminophen) mixed with a wide variety of excipients was created. Materials that exhibit problematic factors such as fluorescence, variable Raman scattering intensities, and extensive peak overlap were included to challenge the efficacy of chemometric data preprocessing and classification methods. In contrast to spectral matching analyte identification approaches, we have taken a chemometric classification model-based approach to account for the wide variances in spectral data. The first derivative of the Raman spectra from the fingerprint region (750-1900 cm(-1)) yielded the best classifications. Using a robust segmented cross-validation method, correct classification rates of better than ?90% could be attained with regression-based classification, compared to ?35% for SIMCA. This study demonstrates that even with very high degrees of sample variance, as evidenced by dramatic changes in Raman spectra, it is possible to obtain reasonably reliable identification using a combination of Raman spectroscopy and chemometrics. The model sample set can now be used to validate more advanced chemometric or machine learning algorithms being developed for the identification of analytes such as illicit narcotics. PMID:20925980

HPTLC Hyphenated with FTIR: Principles, Instrumentation and Qualitative Analysis and Quantitation  

NASA Astrophysics Data System (ADS)

In recent years, much effort has been devoted to the coupling of high-performance thin-layer chromatography (HPTLC) with spectrometric methods because of the robustness and simplicity of HPTLC and the need for detection techniques that provide identification and determination of sample constituents. IR is one of the spectroscopic methods that have been coupled with HPTLC. IR spectroscopy has a high potential for the elucidation of molecular structures, and the characteristic absorption bands can be used for compound-specific detection. HPTLC-FTIR coupled method has been widely used in the modern laboratories for the qualitative and quantitative analysis. The potential of this method is demonstrated by its application in different fields of analysis such as drug analysis, forensic analysis, food analysis, environmental analysis, biological analysis, etc. The hyphenated HPTLC-FTIR technique will be developed in the future with the aim of taking full advantage of this method.

Silent loss and the clinical encounter: Parents' and physicians' experiences of stillbirth-a qualitative analysis  

PubMed Central

Background In the United States, an estimated 70 stillbirths occur each day, on average 25,000 each year. Research into the prevalence and causes of stillbirth is ongoing, but meanwhile, many parents suffer this devastating loss, largely in silence, due to persistent stigma and taboo; and many health providers report feeling ill equipped to support grieving parents. Interventions to address bereavement after neonatal death are increasingly common in U.S. hospitals, and there is growing data on the nature of parent bereavement after a stillbirth. However, further research is needed to evaluate supportive interventions and to investigate the parent-clinician encounter during hospitalization following a stillbirth. Qualitative inquiry offers opportunities to better understand the lived experience of parents against the backdrop of clinicians’ beliefs, intentions, and well-meaning efforts to support grieving parents. Methods We present a secondary qualitative analysis of transcript data from 3 semi-structured focus groups conducted with parents who had experienced a stillbirth and delivered in a hospital, and 2 focus groups with obstetrician-gynecologists. Participants were drawn from the greater Seattle region in Washington State. We examine parents’ and physicians’ experiences and beliefs surrounding stillbirth during the clinical encounter using iterative discourse analysis. Results Women reported that the cheery, bustling environment of the labor and delivery setting was a painful place for parents who had had a stillbirth, and that the well-meaning attempts of physicians to offer comfort often had the opposite effect. Parents also reported that their grief is deeply felt but not socially recognized. While physicians recognized patients’ grief, they did not grasp its depth or duration. Physicians viewed stillbirth as an unexpected clinical tragedy, though several considered stillbirth less traumatic than the death of a neonate. In the months and years following a stillbirth, these parents continue to memorialize their children as part of their family. Conclusions Hospitals need to examine the physical environment for deliveries and, wherever possible, offer designated private areas with staff trained in stillbirth care. Training programs in obstetrics need to better address the bereavement needs of parents following a stillbirth, and research is needed to evaluate effective bereavement interventions, accounting for cultural variation. Critical improvements are also needed for mental health support beyond hospitalization. Finally, medical professionals and parents can play an important role in reversing the stigma that surrounds stillbirth.

Scoring methods and results for qualitative evaluation of public health impacts from the Hanford high-level waste tanks. Integrated Risk Assessment Program  

SciTech Connect

The objective of this analysis is to qualitatively rank the Hanford Site high-level waste (HLW) tanks according to their potential public health impacts through various (groundwater, surface water, and atmospheric) exposure pathways. Data from all 149 single-shell tanks (SSTs) and 23 of the 28 double-shell tanks (DSTs) in the Tank Waste Remediation System (TWRS) Program were analyzed for chemical and radiological carcinogenic as well as chemical noncarcinogenic health impacts. The preliminary aggregate score (PAS) ranking system was used to generate information from various release scenarios. Results based on the PAS ranking values should be considered relative health impacts rather than absolute risk values.

Qualitative analysis of controlled release ciprofloxacin/carbopol 934 mucoadhesive suspension  

PubMed Central

Mucoadhesive polymeric (carbopol 934) suspension of ciprofloxacin was prepared by ultrasonication and optimized with the aim of developing an oral controlled release gastro-retentive dosage form. The qualitative analysis of the formulation was performed by fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray powder diffraction (XRD), and scanning electron microscopy (SEM) analyses. FTIR (400 cm-1 to 4000 cm-1 region) and Raman (140 to 2400 cm-1 region) Spectroscopic studies were carried out and the spectra were used for interpretation. XRD data of pure drug, polymer and the formulation were obtained using a powder diffractometer scanned from a Bragg's angle (2?) of 10° to 70°. The dispersion of the particle was observed using SEM techniques. The particle size distribution and aspect ratio of particles in the polymeric suspension were obtained from SEM image analysis. The results from FTIR and Raman spectroscopic analyses suggested that, in formulation, the carboxylic groups of ciprofloxacin and hydroxyl groups of C934 undergo a chemical interaction leading to esterification and hydrogen bonding. The XRD data suggested that the retention of crystalline nature of ciprofloxacin in the formulation would lead to increase in stability and drug loading; decrease in solubility; and delay in release of the drug from polymeric suspension with better bioavailability and penetration capacity. The SEM image analysis indicated that, in the formulation maximum particles were having aspect ratio from 2 to 4 and standard deviation was very less which provided supporting evidences for homogeneous, uniformly dispersed, stable controlled release ciprofloxacin suspension which would be pharmaceutically acceptable.

Qualitative data analysis for an exploratory sensory study of Grechetto wine.  

PubMed

Grechetto is a traditional white-grape vine, widespread in Umbria and Lazio regions in central Italy. Despite the wine commercial diffusion, little literature on its sensory characteristics is available. The present study is an exploratory research conducted with the aim of identifying the sensory markers of Grechetto wine and of evaluating the effect of clone, geographical area, vintage and producer on sensory attributes. A qualitative sensory study was conducted on 16 wines, differing for vintage, Typical Geographic Indication, and clone, collected from 7 wineries, using a trained panel in isolation who referred to a glossary of 133 white wine descriptors. Sixty-five attributes identified by a minimum of 50% of the respondents were submitted to a correspondence analysis to link wine samples to the sensory attributes. Seventeen terms identified as common to all samples are considered as characteristics of Grechetto wine, 10 of which olfactory: fruity, apple, acacia flower, pineapple, banana, floral, herbaceous, honey, apricot and peach. In order to interpret the relationship between design variables and sensory attributes data on 2005 and 2006 wines, the 28 most discriminating descriptors were projected in a principal component analysis. The first principal component was best described by olfactory terms and the second by gustative attributes. Good reproducibility of results was obtained for the two vintages. For one winery, vintage effect (2002-2006) was described in a new principal component analysis model applied on 39 most discriminating descriptors, which globally explained about 84% of the variance. In the young wines the notes of sulphur, yeast, dried fruit, butter, combined with herbaceous fresh and tropical fruity notes (melon, grapefruit) were dominant. During wine aging, sweeter notes, like honey, caramel, jam, become more dominant as well as some mineral notes, such as tuff and flint. PMID:20103144

Between-sex differences in romantic jealousy: substance or spin? A qualitative analysis.  

PubMed

An influential evolutionary account of romantic jealousy proposes that natural selection shaped a specific sexually-dimorphic psychological mechanism in response to relationship threat. However, this account has faced considerable theoretical and methodological criticism and it remains unclear whether putative sex differences in romantic jealousy actually exist and, if they do, whether they are consistent with its predictions. Given the multidimensional nature of romantic jealousy, the current study employed a qualitative design to examine these issues. We report the results of sixteen semi-structured interviews that were conducted with heterosexual men and women with the purpose of exploring the emotions, cognitions and behaviors that formed their subjective, lived experience in response to relationship threat. Interpretative phenomenological analysis revealed four super-ordinate themes ("threat appraisal", "emotional episodes", "sex-specific threat" and "forgive and forget") and unequivocal sex differences in romantic jealousy consistent with the evolutionary account. Self-esteem, particularly when conceptualized as an index of mate value, emerged as an important proximal mediator for both sexes. However, specific outcomes were dependent upon domains central to the individual's self concept that were primarily sex-specific. The findings are integrated within the context of existing self-esteem and evolutionary theory and future directions for romantic jealousy research are suggested. PMID:22833855

A qualitative analysis of case managers' use of harm reduction in practice.  

PubMed

The harm reduction approach has become a viable framework within the field of addictions, yet there is limited understanding about how this approach is implemented in practice. For people who are homeless and have co-occurring psychiatric and substance use disorders, the Housing First model has shown promising results in employing such an approach. This qualitative study utilizes ethnographic methods to explore case managers' use of harm reduction within Housing First with a specific focus on the consumer-provider relationship. Analysis of observational data and in-depth interviews with providers and consumers revealed how communication between the two regarding the consumer's substance use interacted with the consumer-provider relationship. From these findings emerged a heuristic model of harm reduction practice that highlighted the profound influence of relationship quality on the paths of communication regarding substance use. This study provides valuable insight into how harm reduction is implemented in clinical practice that ultimately has public health implications in terms of more effectively addressing high rates of addiction that contribute to homelessness and health disparities.

Personal Growth During Internship: A Qualitative Analysis of Interns' Responses to Key Questions  

PubMed Central

BACKGROUND During clinical training, house officers frequently encounter intense experiences that may affect their personal growth. The purpose of this study was to explore processes related to personal growth during internship. DESIGN Prospective qualitative study conducted over the course of internship. PARTICIPANTS Thirty-two postgraduate year (PGY)-1 residents from 9 U.S. internal medicine training programs. APPROACH Every 8 weeks, interns responded by e-mail to an open-ended question related to personal growth. Content analysis methods were used to analyze the interns' writings to identify triggers, facilitators, and barriers related to personal growth. RESULTS Triggers for personal growth included caring for critically ill or dying patients, receiving feedback, witnessing unprofessional behavior, experiencing personal problems, and dealing with the increased responsibility of internship. Facilitators of personal growth included supportive relationships, reflection, and commitment to core values. Fatigue, lack of personal time, and overwhelming work were barriers to personal growth. The balance between facilitators and barriers may dictate the extent to which personal growth occurs. CONCLUSIONS Efforts to support personal growth during residency training include fostering supportive relationships, encouraging reflection, and recognizing interns' core values especially in association with powerful triggers.

Nonlinear spinor fields in an anisotropic universe filled with viscous fluid: Exact solutions and qualitative analysis  

NASA Astrophysics Data System (ADS)

A self-consistent system containing a nonlinear spinor field and a Bianchi type-I (BI) gravitational field is considered in the presence of a viscous fluid and the cosmological constant. Nonlinear terms in the Lagrangian spinor-field appear either due to a self-action, or as a result of interaction with a scalar field. They are given by power functions of the invariants I and J, constructed from the bilinear spinor forms S and P. As far as the viscosity is concerned, it is a function of the energy density ? exhibiting a power-law behavior. Self-consistent solutions of the spinor, scalar, and gravitational field equations are derived. The obtained solutions are expressed in terms of the function ?( t), where ? is the volume scale in the BI-type Universe. A system of equations for ?, H, and ? is derived, where H is the Hubble constant, and ? is the viscous-flow energy. Exact solutions of the system are found for some special choices of the nonlinearity and viscosity. A complete qualitative analysis of the evolution at the boundaries is performed, and numerical solutions are obtained in the most interesting cases. In particular, it is shown that the system has Big Rip type solutions, which is typical for systems containing a phantom matter.

Pathologic Analysis of Control Plans for Air Pollution Management in Tehran Metropolis: A Qualitative Study  

PubMed Central

Background: Regarding the importance of air pollution issue for large cities, as Tehran metropolis, many plans, programs, projects and regulations have been developed to manage urban air pollution. However, most of them failed to decline the pollution. The purpose of this study is to pathologically analyze air-pollution control plans in order to offer effective solutions for Tehran metropolis. Methods: A qualitative content analysis and a semi-structured interview with 14 practicing professionals were used to identify key causes and sources of Tehran's air pollution, to recognize challenges and obstacles towards effective performance of air-pollution control plans in this metropolitan area, and to suggest the most effective controlling solutions. Results: Challenges related to air-pollution control plans can be divided into two major categories: Firstly lack of integrated and organized stewardship and secondly those related to political, economical, social and technical environmental abbreviated as PEST, challenges. For effective control of the Tehran air pollution, the following eight controlling alternatives were identified: Systematization of plan preparation process, organizing the stewardship, standardization and utilization of new technologies and professional experts, cultural and infrastructural development, realization of social justice, developing coordination and controlling mechanisms, improving citizen's participatory capacity, and focusing on effective management of fuel and energy. Conclusions: Controlling air pollution in Tehran should be considered as a priority for policymakers to make enforcements through applying a systemic cycle of preparation effective and comprehensive plans. Further, implement the enforcements and evaluate the environmental impact of the plans through involving all stakeholders.

Learning effects of thematic peer-review: a qualitative analysis of reflective journals on spiritual care.  

PubMed

This study describes the learning effects of thematic peer-review discussion groups (Hendriksen, 2000. Begeleid intervisie model, Collegiale advisering en probleemoplossing, Nelissen, Baarn.) on developing nursing students' competence in providing spiritual care. It also discusses the factors that might influence the learning process. The method of peer-review is a form of reflective learning based on the theory of experiential learning (Kolb, 1984. Experiential learning, Experience as the source of learning development. Englewoods Cliffs, New Jersey, Prentice Hill). It was part of an educational programme on spiritual care in nursing for third-year undergraduate nursing students from two nursing schools in the Netherlands. Reflective journals (n=203) kept by students throughout the peer-review process were analysed qualitatively The analysis shows that students reflect on spirituality in the context of personal experiences in nursing practice. In addition, they discuss the nursing process and organizational aspects of spiritual care. The results show that the first two phases in the experiential learning cycle appear prominently; these are 'inclusion of actual experience' and 'reflecting on this experience'. The phases of 'abstraction of experience' and 'experimenting with new behaviour' are less evident. We will discuss possible explanations for these findings according to factors related to education, the students and the tutors and make recommendations for follow-up research. PMID:19027200

Rapid qualitative phase analysis in highly textured thin films by x-ray diffraction.  

PubMed

Phase analysis of highly out-of-plane textured specimens using x-ray diffraction is usually complicated due to the disappearance of most of the x-ray peaks in a common theta/2 theta diffraction geometry. In this paper, we propose a technique, where powderlike spectra of textured samples are obtained by multiaxial x-ray diffraction scans. This technique is a simple, yet powerful method which allows for significant improvement in thin film characterization and provides several types of information about the samples, such as the rapid qualitative identification of phases using common powder x-ray diffraction spectra databases, texture distribution, and quantitative residual stress analysis.

A qualitative analysis of the information needs of informal carers of terminally ill cancer patients.  

PubMed

This article discusses issues relating to information arising from a qualitative study of the experiences of informal carers of terminally ill cancer patients. Qualitative data analysis, drawing on methods of literary criticism, revealed that information was a key area in carers' experience. The findings are presented in the context of needing to provide individualized care to every family and deal with information needs relating to the illness and prognosis. The question of who is in possession of what information is raised, and the effect that this can have on couples is discussed, together with the issue of false information which carers may receive. The discussion centres on the complexity of understanding carers' information needs and considers how these are affected by the context within which carers operate. The work of Glaser and Strauss on awareness contexts is discussed in this respect. Finally, the importance of the nurse's role as a sensitive mediator of information is considered. PMID:10214173

Object orientated automated image analysis: quantitative and qualitative estimation of inflammation in mouse lung  

PubMed Central

Historically, histopathology evaluation is performed by a pathologist generating a qualitative assessment on thin tissue sections on glass slides. In the past decade, there has been a growing interest for tools able to reduce human subjectivity and improve workload. Whole slide scanning technology combined with object orientated image analysis can offer the capacity of generating fast and reliable results. In the present study, we combined the use of these emerging technologies to characterise a mouse model for chronic asthma. We monitored the inflammatory changes over five weeks by measuring the number of neutrophils and eosinophils present in the tissue, as well as, the bronchiolar associated lymphoid tissue (BALT) area on whole lungs sections. We showed that inflammation assessment could be automated efficiently and reliably. In comparison to human evaluation performed on the same set of sections, computer generated data was more descriptive and fully quantitative. Moreover optimisation of our detection parameters allowed us to be to more sensitive and to generate data in a larger dynamic range to traditional experimental evaluation, such as bronchiolar lavage (BAL) inflammatory cell counts obtained by flow cytometry. We also took advantage of the fact that we could increase the number of samples to be analysed within a day. Such optimisation allowed us to determine the best study design and experimental conditions in order to increase statistical significance between groups. In conclusion, we showed that combination of whole slide digital scanning and image analysis could be fully automated and deliver more descriptive and biologically relevant data over traditional methods evaluating histopathological pulmonary changes observed in this mouse model of chronic asthma.

Factors affecting adherence to antihypertensive medication in Greece: results from a qualitative study  

PubMed Central

Introduction: Although hypertension constitutes a major risk factor for cardiovascular morbidity and mortality, research on adherence to antihypertensive treatment has shown that at least 75% of patients are not adherent because of the combined demographic, organizational, psychological, and disease- and medication-related factors. This study aimed to elicit hypertensive patients’ beliefs on hypertension and antihypertensive treatment, and their role to adherence. Methods: Transcripts from semistructured interviews and focus groups were content analyzed to extract participants’ beliefs about hypertension and antihypertensive treatment, and attitudes toward patient–physician and patient–pharmacist relationships. Results: Hypertension was considered a very serious disease, responsible for stroke and myocardial infarction. Participants expressed concerns regarding the use of medicines and the adverse drug reactions. Previous experience with hypertension, fear of complications, systematic disease management, acceptance of hypertension as a chronic disease, incorporation of the role of the patient and a more personal relationship with the doctor facilitated adherence to the treatment. On the other hand, some patients discontinued treatment when they believed that they had controlled their blood pressure. Conclusion: Cognitive and communication factors affect medication adherence. Results could be used to develop intervention techniques to improve medication adherence.

A Qualitative Analysis of Acute Skin Toxicity among Breast Cancer Radiotherapy Patients  

PubMed Central

Objectives One of the most common acute side effects of breast cancer radiotherapy is treatment induced skin changes, referred to as skin toxicity. Yet no research to date has focused expressly on skin toxicity-related quality of life in breast cancer radiotherapy patients. Therefore, our aim was to use qualitative approaches to better understand the impact of skin toxicity on quality of life. Methods Semi-structured interviews were conducted with 20 women (Stage 0-III breast cancer), during their last week of external beam radiotherapy. Each interview was transcribed verbatim, and thematic analysis was performed. Results Three themes were identified based on the interview responses: First, skin changes affect multiple dimensions of quality of life. They cause physical discomfort, body image disturbance, emotional distress, and impair both day-to-day functioning and satisfaction with radiation treatment. Second, individual differences affect women’s experiences. Generally African-American women, younger women, women who are not currently in a relationship, women who are being treated during the summer, and women who are more invested in their appearance are more distressed by skin toxicity. Third, women use a variety of symptom management strategies including self-medication, complementary/alternative medicine approaches, and psychological strategies. Conclusions Implications of results are: 1) Skin toxicity affects numerous dimensions of quality of life, and assessment approaches and psychosocial interventions should address this; 2) individual differences may affect the experience of skin toxicity, and should be considered in treatment and education approaches; and 3) participants’ own creativity and problem-solving should be used to improve the treatment experience.

Netto shinju, or Internet group suicide, is a contemporary form of Japanese suicide where strangers connect on the Internet and make plans to commit suicide together. In the past decade, numerous incidents have occurred whereby young Japanese make contact on the Internet, exchange tips on suicide methods, and make plans to meet offline for group/individual suicide. A systematic qualitative content/thematic analysis of online communications posted on a popular Japanese suicide bulletin board yielded a textured, thematic understanding of this phenomenon. Themes identified reflected Shneidman's theory of suicide but with an emphasis on interpersonal concerns that are embedded in Japanese culture. PMID:23666942

Qualitative and quantitative analysis of stability and instability dynamics of positive lattice solitons.

We present a unified approach for qualitative and quantitative analysis of stability and instability dynamics of positive bright solitons in multidimensional focusing nonlinear media with a potential (lattice), which can be periodic, periodic with defects, quasiperiodic, single waveguide, etc. We show that when the soliton is unstable, the type of instability dynamic that develops depends on which of two stability conditions is violated. Specifically, violation of the slope condition leads to a focusing instability, whereas violation of the spectral condition leads to a drift instability. We also present a quantitative approach that allows one to predict the stability and instability strength. PMID:18999546

What Leads Indians to Participate in Clinical Trials? A Meta-Analysis of Qualitative Studies  

PubMed Central

Background With the globalization of clinical trials, large developing nations have substantially increased their participation in multi-site studies. This participation has raised ethical concerns, among them the fear that local customs, habits and culture are not respected while asking potential participants to take part in study. This knowledge gap is particularly noticeable among Indian subjects, since despite the large number of participants, little is known regarding what factors affect their willingness to participate in clinical trials. Methods We conducted a meta-analysis of all studies evaluating the factors and barriers, from the perspective of potential Indian participants, contributing to their participation in clinical trials. We searched both international as well as Indian-specific bibliographic databases, including Pubmed, Cochrane, Openjgate, MedInd, Scirus and Medknow, also performing hand searches and communicating with authors to obtain additional references. We enrolled studies dealing exclusively with the participation of Indians in clinical trials. Data extraction was conducted by three researchers, with disagreement being resolved by consensus. Results Six qualitative studies and one survey were found evaluating the main themes affecting the participation of Indian subjects. Themes included Personal health benefits, Altruism, Trust in physicians, Source of extra income, Detailed knowledge, Methods for motivating participants as factors favoring, while Mistrust on trial organizations, Concerns about efficacy and safety of trials, Psychological reasons, Trial burden, Loss of confidentiality, Dependency issues, Language as the barriers. Conclusion We identified factors that facilitated and barriers that have negative implications on trial participation decisions in Indian subjects. Due consideration and weightage should be assigned to these factors while planning future trials in India.

Online support for parents of preterm infants: a qualitative and content analysis of Facebook 'preemie' groups.  

PubMed

OBJECTIVE: To qualitatively evaluate the content of communication in Facebook communities dedicated to preterm infants. DESIGN: The 25 largest public English-language Facebook groups focusing on preterm infants were identified. For each group, the 20 most recent wallposts and a maximum of the 15 first comments to these wallposts, and the 15 most recent discussion topics were analysed according to a thematic coding scheme. The purpose of each group was determined and personal characteristics of administrators and active posters were analysed. RESULTS: 1497 individual Facebook groups focusing on preterm infants were found, wherein the 25 largest had between 391 and 14 986 members. Non-profit fundraising groups comprised 48% of analysed groups and had the greatest number of members (median 1450, IQR 548-5435), followed by general awareness (24% of all groups, members: median 1183, IQR 658-2116) and interpersonal support groups (28% of all groups, members: median 823, IQR 484-1022). 85.0% of administrators and 91.5% of posters were women, and two-thirds of posts had been written by mothers of preterm infants. The analysis of posts, comments and discussion topics (n=1054) showed that 'information sharing' (31%) and 'interpersonal support' (53%) were the most common purposes. CONCLUSIONS: Facebook groups related to preterm birth have become a popular tool for fundraising and awareness-raising. However, most group members use these forums for information sharing and interpersonal support. Given their popularity and reach, further research is warranted to understand the motivations, implications and risks of dynamic online communication among parents of preterm infants. PMID:23759520

The use of linear ion trap for qualitative analysis of phytochemicals in Korean ginseng tea.  

PubMed

A new approach to qualitative analysis of ginsenosides in challenging matrices was developed on the basis of high-performance liquid chromatography/tandem mass spectrometry. Using the extracts from samples of ginseng tea, the approach was validated. Analysis of extracts was carried out using a reversed-phase chromatography with SB-C18 sorbent. For compound identification, electrospray ionization and a quadrupole/linear ion trap mass-spectrometer in different modes were used. A meticulous study of the fragmentation of ginsenosides in the linear ion trap and its application for analysis of these compounds was performed in this work. The accuracy of the identification was proven with standards of ginsenosides Rb1, Rg1, Re, Rf, Rd, Rb2, Rb3 and Rc. PMID:23280398

A Qualitative Secondary Evaluation of Statewide Follow-Up Interviews for Abnormal Newborn Screening Results for Cystic Fibrosis and Sickle Cell Hemoglobinopathy  

PubMed Central

Purpose The purpose of this qualitative analysis was to assess parental acceptability of large-scale, telephone follow-up regarding their infants' newborn screening (NBS) results indicating carrier status for sickle cell hemoglobinopathy (SCH) and cystic fibrosis (CF). Methods Analysis of 195 interview transcripts focused on parents' responses to two open-ended questions “What was your reaction to being called by me?” and “What do you think of the state newborn screening program having follow-up people calling parents like you?” Responses were coded using conventional content analysis procedures and non-parametric tests were performed to analyze quantitative data. Results Most parents reported favorable opinions about the follow-up. Favorable opinions were associated with several emotional reactions to receiving follow-up (p<0.001), and three reasons why parents found the interview beneficial (p<0.05): it provided information, clarified NBS results, and answered questions. Seventeen parents of SCH carriers reportedly had not been told their infant's NBS results and received them for the first time during the follow-up interview. Conclusion Parents of CF and SCH carrier infants had favorable opinions and identified specific benefits to receiving follow-up contact. This analysis demonstrates an information deficit among carrier parents and illustrates the importance of NBS follow-up and need for comprehensive communication and counseling.

There have been few qualitative investigations evaluating Mindfulness-Based Stress Reduction (MBSR) in breast cancer populations. The nested qualitative analysis reported here explores the acceptability and the perceived effect of MBSR. As part of a larger randomised controlled evaluative trial, 92 participants with stages 0 to III breast cancer completed a short proforma following week 8 of a MBSR programme conducted at The Haven, an integrated cancer support centre in London, UK in 2005-2006. Following thematic analysis, the most positive experiences from participants (n = 92) were reported to be; 1) being calmer, centred, at peace, connected and more confident; 2) the value of mindfulness practice; 3) being more aware; 4) coping with stress, anxiety and panic; 5) accepting things as they are, being less judgemental of myself and others; 6) improved communication and personal relationships and 7) making time and creating space for myself. All participants asked (n = 39) said that following MBSR training they had become more mindful. These understandings will be able to help shape the future teaching of MBSR in breast cancer.

Iranian nurses' perception of spirituality and spiritual care: a qualitative content analysis study  

PubMed Central

The purpose of the present study was to explore nurses’ perception about spirituality and spiritual care. A qualitative content analysis approach was conducted on 20 registered nurses interviewed using unstructured strategy in 2009. Three themes emerged from the data analysis: 1) “meaning and purpose of work and life” including ‘spiritualistic view to profession’, ‘commitment and professional responsibility’, and ‘positive attitude’; 2) “religious attitude” including ‘God approval’, ‘spiritual reward’, ‘taking advice’, ‘inner belief in the Supreme Being’, ‘faith-based interactions and altruism’; 3) “transcendence-seeking” including ‘need for respect’ and ‘personal–professional transcendence’. Therefore, the spirituality produces maintenance, harmony and balance in nurses in relation to God. Spiritual care focuses on respecting patients, friendly and sympathetic interactions, sharing in rituals and strengthening patients and nurses’ inner energy. This type of spirituality gives a positive perspective to life and profession, peaceful interactions, a harmonious state of mind, and acts as a motivator among nurses to promote nursing care and spirituality.

A simple apparatus for quick qualitative analysis of CR39 nuclear track detectors  

SciTech Connect

Quantifying the ion pits in Columbia Resin 39 (CR39) nuclear track detector from Thomson parabolas is a time consuming and tedious process using conventional microscope based techniques. A simple inventive apparatus for fast screening and qualitative analysis of CR39 detectors has been developed, enabling efficient selection of data for a more detailed analysis. The system consists simply of a green He-Ne laser and a high-resolution digital single-lens reflex camera. The laser illuminates the edge of the CR39 at grazing incidence and couples into the plastic, acting as a light pipe. Subsequently, the laser illuminates all ion tracks on the surface. A high-resolution digital camera is used to photograph the scattered light from the ion tracks, enabling one to quickly determine charge states and energies measured by the Thomson parabola.

The experience of implementing evidence-based practice change: a qualitative analysis.  

PubMed

The Oncology Nursing Society (ONS) and ONS Foundation worked together to develop the Institute for Evidence-Based Practice Change (IEBPC) program to facilitate the implementation of evidence-based practice (EBP) change in nursing. This analysis describes the experience of 19 teams of nurses from various healthcare settings who participated in the IEBPC program. Qualitative analysis of verbatim narratives of activities and observations during the process of implementing an EBP project was used to identify key themes in the experience. EBP implementation enabled participants to learn about their own practice and to experience empowerment through the evidence, and it ignited the spirit of inquiry, team work, and multidisciplinary collaboration. Experiences and lessons learned from nurses implementing EBP can be useful to others in planning EBP implementation. PMID:24080054

Temporal Patterns of Subjective Experiences and Self-Regulation during Ramadan Fasting among Elite Archers: A Qualitative Analysis  

PubMed Central

Purpose Some major competitions (e.g. London Olympics, 2012) are scheduled during the Ramadan fasting month. Little attention has been given to explore the archers’ performance related subjective experiences with a qualitative method. Therefore, this study addressed individual archers’ subjective experiences within the framework of self-regulation during Ramadan. Methods Eleven elite Malaysian Muslim fasting archers volunteered to participate in the study. Grounded theory was the qualitative approach used to examine the subjective experiences of athletes during Ramadan. Interviews were conducted and inductive content analysis was adopted to identify the temporal patterns of self-regulation of subjective experiences across the fasting period. Results Inductive content analysis identified (a) physical, (b) mental,(c) emotional, (d) behavioral, and (e) spiritual experiences. Overall patterns revealed that experiences associated with physical, emotional, behavioral, and spiritual dimensions dominated in the first phase of fasting, while the mental dimension surfaced increasingly in the latter phase of fasting. Conclusions The trend showed changes in the patterns of experiences among the major domains across the temporal dimension. Athletes reported increased subjective experiences in mental factors toward the latter half of the fasting period. Practitioners should emphasize on mental aspects of training, as these appear to be salient in archery performance.

Adherence with oral chemotherapy: results from a qualitative study of the behaviour and representations of patients and oncologists.  

PubMed

Oral chemotherapy is increasingly used in oncology. Poor adherence, that is, non-respect of medical advice about taking the therapy and surveillance of adverse effects, is the main risk associated with this administration route. Poor adherence may be explained by non-adherence by the patient to the treatment, misunderstanding the advice or it could also reflect the poor adaptation of the healthcare team to a new administration route. Here we report the results from a qualitative study that aimed to describe and understand existing practice for capecitabine, an oral chemotherapy, which is used for the treatment of metastatic breast and colon cancer. We interviewed 42 patients who were receiving oral capecitabine in groups and individually as well as 10 prescribers. This study was carried out in two specialist cancer centres. The results showed a wide diversity in the prescribers' practices, who make decisions based on their experience of practice guidelines for intravenous chemotherapies. Although the results for the patients do not suggest deliberate non-adherence, they show poor observance of the dose schedule. The most important result of this study is the patient's inability to identify and to report important signs of harmful toxicity. PMID:20649809

A study of expert problem-solving in qualitative organic analysis using a computer simulation  

NASA Astrophysics Data System (ADS)

A qualitative case study of eight doctoral level organic chemists from academia (6) and industry (2) solved eleven qualitative organic analysis problems using the Identification of Organic CompoundsRTM software computer simulation. Think-aloud protocols were analyzed for content knowledge and strategic knowledge to account for expert performance. Each of the eleven qualitative organic analysis problems included a variety of functional groups and structures and was solved in a computer-simulated environment to allow for extensive problem-solving by the experts and to evaluate the simulation's ability to model the problem-solving environment. The data provided consisted of the typical instrumentation available to university undergraduate students, including infrared, proton nuclear magnetic resonance, carbon-13 nuclear magnetic resonance, and mass spectral data. Traditional wet chemistry data were also provided in the software, including solubility tests, fusion tests, classification tests, and derivatives. The subjects from industry did not effectively utilize the wet chemistry techniques, whereas the subjects from academia emphasized spectrometric techniques but also used wet chemistry techniques. Only two of the subjects made the determination of an empirical formula an initial part of their problem-solving strategy. This strategy was used on 24 percent of the problems. On 16 percent of the problems the subjects reverted to calculating an empirical formula when the problem became difficult to solve. The most effective strategy for utilizing the percent composition was to check the answer's percent composition with the elemental analysis. This was 100 percent successful and was used on 15 percent of problems. The elemental analysis was not used quantitatively by these experts on 45 percent of the problems. Problem-solving was idiosyncratic in that subjects utilized a particular experimental method that they were the most comfortable interpreting as their initial experimental space search. Then subsequent problem-solving largely consisted of a series of explorations of the experimental space with subsequent searches for confirmation of model-building conclusions drawn from the data. Derivatives were used exclusively by the academic chemists both to search for solutions and to confirm proposed solutions.

The impact of vascular comorbidities on qualitative error analysis of executive impairment in Alzheimer's disease.  

PubMed

Recent evidence suggests that patients with Alzheimer's disease (AD) and vascular comorbidities (VC) perform worse across measures of verbal reasoning and abstraction when compared to patients with AD alone. We performed a qualitative error analysis of Wechsler Adult Intelligence Scale-III Similarities zero-point responses in 45 AD patients with varying numbers of VC, including diabetes, hypertension, and hypercholesterolemia. Errors were scored in set if the answer was vaguely related to how the word pair was alike (e.g., dog-lion: "they can be trained") and out of set if the response was unrelated ("a lion can eat a dog"). AD patients with 2-3 VC did not differ on Similarities total score or qualitative errors from AD patients with 0-1 VC. When analyzing the group as a whole, we found that increasing numbers of VC were significantly associated with increasing out of set errors and decreasing in set errors in AD. Of the vascular diseases investigated, it was only the severity of diastolic blood pressure that significantly correlated with out of set responses. Understanding the contribution of VC to patterns of impairment in AD may provide support for directed patient and caregiver education concerning the presentation of a more severe pattern of cognitive impairment in affected individuals.

Self-rated assessment of needs for mental health care: a qualitative analysis.  

PubMed

This study explored perceived mental health-related needs and barriers to meeting them in primary and mental health care settings. Fifty-one participants completed the Perceived Need for Care Questionnaire and an interview to qualitatively explore the meanings behind self-identified needs for medication, information, counselling, practical help, and skills development. Qualitative content analysis indicated perceived needs for care are multifaceted. Dissatisfaction with taking medication may coexist with perceiving medication needs as met; information needs predominantly concerned wanting to better understand one's illness; and communication was the main perceived barrier to meeting these needs. Counselling-related needs included being listened to, supported or assisted with problem-solving, with service attitudes, staff expertise or cost seen as limiting access. Needs for practical help and skills development were described as unmet or addressed by family, and help-seeking for these needs constrained by efforts to self-manage, insufficient information, and affordability. Collaborative care and information-sharing appear important to better meet mental health-related perceived needs. PMID:21691820

A qualitative analysis of a randomized controlled trial comparing a cognitive-behavioral treatment with education  

PubMed Central

Cognitive Behavioral Therapy (CBT) is a widely accepted psychosocial treatment for chronic pain. However, the efficacy of CBT has not been investigated within a rural setting. Furthermore, few studies have utilized first-person accounts to qualitatively investigate the key treatment elements and processes of change underlying the well-documented quantitative improvements associated with CBT. To address these gaps, we conducted a randomized controlled trial (RCT) investigating the efficacy of group CBT compared to an active education condition (EDU) within a rural, low-literacy population. Post-treatment semi-structured interviews of 28 CBT and 24 EDU treatment completers were qualitatively analyzed. Emerging themes were collated to depict a set of finalized thematic maps to visually represent the patterns inherent in the data. Patterns were separated into procedural elements and presumed change processes of treatment. Key themes, subthemes, and example extracts for CBT and EDU are presented; unique and shared aspects pertaining to the thematic maps are discussed. Results indicate that while both groups benefited from the program, the CBT group described more breadth and depth of change as compared to the EDU group. Importantly, this study identified key treatment elements and explored possible processes of change from the patients’ perspective. Perspective This qualitative article describes patient-identified key procedural elements and change process factors associated with psychosocial approaches for chronic pain management. Results may guide further adaptations to existing treatment protocols for use within unique, underserved chronic pain populations. Continued development of patient-centered approaches may help reduce health, treatment and ethnicity disparities.

Quantitative and Qualitative Analysis of Bacteria in Er(III) Solution by Thin-Film Magnetopheresis.  

PubMed

Magnetic deposition, quantitation, and identification of bacteria reacting with the paramagnetic trivalent lanthanide ion, Er, was evaluated. The magnetic deposition method was dubbed thin-film magnetopheresis. The optimization of the magnetic deposition protocol was accomplished with Escherichia coli as a model organism in 150 mM NaCl and 5 mM ErCl(3) solution. Three gram-positive bacteria, Staphylococcus epidermidis, Staphylococcus saprophyticus, and Enterococcus faecalis, and four gram-negative bacteria, E. coli, Pseudomonas aeruginosa, Proteus mirabilis, and Klebsiella pneumoniae, were subsequently investigated. Quantitative analysis consisted of the microscopic cell count and a scattered-light scanning of the magnetically deposited material aided by the computer data acquisition system. Qualitative analysis consisted of Gram stain differentiation and fluorescein isothiocyanate staining in combination with selected antisera against specific types of bacteria on the solid substrate. The magnetic deposition protocol allowed quantitative detection of E. coli down to the concentration of 10 CFU ml, significant in clinical diagnosis applications such as urinary tract infections. Er did not interfere with the typical appearance of the Gram-stained bacteria nor with the antigen recognition by the antibody in the immunohistological evaluations. Indirect antiserum-fluorescein isothiocyanate labelling correctly revealed the presence of E. faecalis and P. aeruginosa in the magnetically deposited material obtained from the mixture of these two bacterial species. On average, the reaction of gram-positive organisms was significantly stronger to the magnetic field in the presence of Er than the reaction of gram-negative organisms. The thin-film magnetophoresis offers promise as a rapid method for quantitative and qualitative analysis of bacteria in solutions such as urine or environmental water. PMID:16348916

Diabetes Portrayals in North American Print Media: A Qualitative and Quantitative Analysis  

PubMed Central

Objectives. This study investigated how media coverage has portrayed diabetes as newsworthy. Methods. The quantitative component involved tabulating diabetes coverage in 2 major Canadian newspapers, 1988–2001 and 1991–2001. The qualitative component focused on high-profile coverage in 2 major US magazines and 2 major Canadian newspapers, 1998–2000. Results. Although coverage did not consistently increase, the quantitative results suggest an emphasis on linking diabetes with heart disease and mortality to convey its seriousness. The qualitative component identified 3 main ways of portraying type 2 diabetes: as an insidious problem, as a problem associated with particular populations, and as a medical problem. Conclusions. Overall, the results suggest that when communicating with journalists, researchers and advocates have stressed that diabetes maims and kills. Yet even when media coverage acknowledged societal forces and circumstances as causes, the proposed remedies did not always include or stress modifications to social contexts. Neither the societal causes of public health problems nor possible societal remedies automatically received attention from researchers or from journalists. Skilled advocacy is needed to put societal causes and solutions on public agendas.

A qualitative analysis of job burnout in eating disorder treatment providers.

Although job burnout is common in mental health care settings, almost no research has examined burnout in eating disorder treatment providers. Using qualitative methodology, this study examined a) perceived contributors of burnout, b) efforts to manage burnout, and c) recommendations for avoiding burnout in a sample of professional eating disorder treatment providers. Recruited via professional organizations, 298 participants completed an online questionnaire designed by the authors. Qualitative responses were coded and grouped into themes. Results indicated that almost all participants worried about their patients' health, which frequently resulted in negative affect (e.g., anxiety, sadness). The most frequently cited contributors to burnout were common characteristics of eating pathology (e.g., chronicity, relapse, symptom severity); patient characteristics (e.g., personality conflict); work-related factors (e.g., time demands); and, financial issues (e.g., inadequate compensation). To avoid burnout, over 90% of participants engaged in self-care behaviors (e.g., exercise, social support). Early-career practitioners were encouraged to utilize supervision, create a work/life balance, engage in self-care, and limit caseloads. These results suggest that supervision and training of eating disorder treatment providers should include burnout management. PMID:22519896

Impact of a general practice based group parenting programme: quantitative and qualitative results from a controlled trial at 12 months  

PubMed Central

Aims: To test the effectiveness at one year of the Webster Stratton Parents and Children Series group parenting programme in a population sample of parents. Methods: In a multicentre block randomised controlled trial, parents of children aged 2–8 years in 116 families who scored in the upper 50% on a validated behaviour inventory, took part in Webster-Stratton's 10 week parenting programme led by trained and supervised health visitors. The following outcome measures were used: Eyberg Child Behaviour Inventory, Goodman Strengths and Difficulties Questionnaire, General Health Questionnaire, Parenting Stress Index, Rosenberg Self Esteem Scale. Results: The intervention significantly reduced child behaviour problems and improved mental health at immediate and 6 month follow ups. One year differences between control and intervention groups were not significant. Qualitative results suggest that these findings might be attributable in part to either Hawthorne effects or contamination of control group. At interview parents described ways in which the programme had improved their mental health. They reported gains in confidence and feeling less stressed. Some also reported beneficial changes in their own and their children's behaviour and improved relationships with their children. Some spoke of a need for further sessions to support the behaviour changes they had managed to make, and some the desire for attendance by both parents. Conclusions: Parenting programmes have the potential to promote mental health and reduce social inequalities, but further work is needed to improve long term effectiveness.

Domestic microwave versus conventional tissue processing: a quantitative and qualitative analysis.  

PubMed

Background: Microwave irradiation has been tried as a replacement for the conventional tissue processing technique in histopathology laboratories for quite some time. Studies have shown that Domestic Microwave Tissue Processing (DMWTP) provides a faster delivery of the tissue sections with a morphology which is similar to that which is seen Conventional Tissue Processing (CTP). But many laboratories still confine the domestic microwave tissue processing method only to the handle selected specimens, for which urgent reports are needed. One of the probable reasons is that, understanding about the number of tissue sections which can be processed using a microwave oven at a time, with the appropriate quality, still remains unclear. Aim: The aim of this study was to quantitatively analyze the optimum number of samples that a domestic microwave could process at a time, as well as to qualitatively analyze the morphological outcome of those tissue sections with that of conventional processing. Materials and Methods: This study was approved by the research and ethical committee of Sree Balaji Medical College and Hospital. A total of 135 paired tissue sections were included in the study. Ten tissue sections (which are mentioned hereafter as A10) were processed in a domestic microwave and their paired 10 tissues were processed by a conventional method. Subsequently, the number of tissues which was to be processed was increased to B15, C20, D25, E30 and F35, after ascertaining that the morphological qualities of the previously processed tissue sections were satisfactory. Sections of 4 ?m thickness were taken and they were stained by the Haematoxylin and Eosin method. The slides of the tissues which were processed by the microwave method and the conventional method were randomly numbered, for a blind study, which were independently evaluated by two observers. The qualities of slides were assessed, based on 4 parameters: the cytoplasmic details, the nuclear details, the tissue architecture and the staining characteristics. The statistical analysis was done by using SPSS 15.0. Results: The morphological outcomes (quality) of the DMWTPs were comparable to that of the CTPs, when the sample load (quantity) in the microwave oven was up to 25 samples. Conclusion: Domestic microwave processing can be effectively used in laboratories with a maximum sample size of 25 samples per load. This has the advantage of being rapid, with its morphological quality being identical to that of conventional processing. PMID:23814723

Exploring interactions of improvers and deteriorators in the group therapy process: a qualitative analysis.  

PubMed

This study examined the interactions of individuals who showed symptom improvement and those who showed deterioration during the course of short-term group psychotherapy. A qualitative hermeneutic analysis was used to identify and describe themes from the group interactions. Both broad group themes, as well as themes specific to improvers and deteriorators, were found. Findings suggest that the differences in group behavior between those who get worse and those who improve are subtle and thus difficult for group leaders to detect. Although the differences were not immediately apparent, a deeper examination of group process did reveal distinct patterns for deteriorators that were different from those of improvers. These patterns of interaction are discussed as well as variables related to client, leader, and group as a whole that may have contributed to the outcome of group members. PMID:19441966

Qualitative Analysis and Travelling Wave Solutions for the Chaffee-Infante Equation  

NASA Astrophysics Data System (ADS)

This paper employs the theory of planar dynamical systems and undetermined coefficient method to study travelling wave solutions to the Chaffee-Infante equation. By qualitative analysis, global phase portraits of the dynamic system corresponding to the equation are obtained for different parameter conditions. Furthermore, the relations between the properties of travelling wave solutions and the diffusion coefficient ? of the equation are investigated. In addition, all possible kink profile solitary wave solutions and approximate damped oscillatory solutions to the equation are obtained by using undetermined coefficient method. Error estimates indicate that the approximate solutions are meaningful. Based on these studies, the main contribution in this paper is to reveal the diffusion effect on travelling wave solutions to the Chaffee-Infante equation.

Requirements for Computer Based-Procedures for Nuclear Power Plant Field Operators Results from a Qualitative Study  

SciTech Connect

Although computer-based procedures (CBPs) have been investigated as a way to enhance operator performance on procedural tasks in the nuclear industry for almost thirty years, they are not currently widely deployed at United States utilities. One of the barriers to the wide scale deployment of CBPs is the lack of operational experience with CBPs that could serve as a sound basis for justifying the use of CBPs for nuclear utilities. Utilities are hesitant to adopt CBPs because of concern over potential costs of implementation, and concern over regulatory approval. Regulators require a sound technical basis for the use of any procedure at the utilities; without operating experience to support the use CBPs, it is difficult to establish such a technical basis. In an effort to begin the process of developing a technical basis for CBPs, researchers at Idaho National Laboratory are partnering with industry to explore CBPs with the objective of defining requirements for CBPs and developing an industry-wide vision and path forward for the use of CBPs. This paper describes the results from a qualitative study aimed at defining requirements for CBPs to be used by field operators and maintenance technicians.

What do physicians gain (and lose) with experience? Qualitative results from a cross-national study of diabetes  

PubMed Central

An empirical puzzle has emerged over the last several decades of research on variation in clinical decision making involving mixed effects of physician experience. There is some evidence that physicians with greater experience may provide poorer quality care than their less experienced counterparts, as captured by various quality assurance measures. Physician experience is traditionally narrowly defined as years in practice or age, and there is a need for investigation into precisely what happens to physicians as they gain experience, including the reasoning and clinical skills acquired over time and the ways in which physicians consciously implement those skills into their work. In this study, we are concerned with 1) how physicians conceptualize and describe the meaning of their clinical experience, and 2) how they use their experience in clinical practice. To address these questions, we analyzed qualitative data drawn from in-depth interviews with physicians from the United States, United Kingdom, and Germany as a part of a larger factorial experiment of medical decision making for diabetes. Our results show that common measures of physician experience do not fully capture the skills physicians acquire over time or how they implement those skills in their clinical work. We found that what physicians actually gain over time is complex social, behavioral and intuitive wisdom as well as the ability to compare the present day patient against similar past patients. These active cognitive reasoning processes are essential components of a forward-looking research agenda in the area of physician experience and decision making. Guideline-based outcome measures, accompanied by underdeveloped age- and years-based definitions of experience, may prematurely conclude that more experienced physicians are providing deficient care while overlooking the ways in which they are providing more and better care than their less experienced counterparts.

Relativity concept inventory: Development, analysis, and results

We report on a concept inventory for special relativity: the development process, data analysis methods, and results from an introductory relativity class. The Relativity Concept Inventory tests understanding of relativistic concepts. An unusual feature is confidence testing for each question. This can provide additional information; for example, high confidence correlated with incorrect answers suggests a misconception. A novel aspect of our data analysis is the use of Monte Carlo simulations to determine the significance of correlations. This approach is particularly useful for small sample sizes, such as ours. Our results show a gender bias that was not present in course assessment, similar to that reported for the Force Concept Inventory.

Patient reported determinants of health: a qualitative analysis of veterans with chronic obstructive pulmonary disease.  

PubMed

Although COPD is a common disorder of veterans who receive care from the Veterans Healthcare Administration (VHA), the perceptions of veterans with COPD about their disease, its effects on their lives, and their interactions with the VHA have not been determined. Utilizing qualitative methodology, we conducted focus groups of veterans with COPD at the Cincinnati VA Medical Center. Participants were selected by systematic sampling from the top quintile of veterans stratified by the cost of healthcare utilization related to a primary diagnosis of COPD and grouped by age and use of supplemental oxygen. All 42 participants were male and had a mean age of 65 years. Analysis of the focus group transcripts demonstrated five major themes: 1) Physical and Functional Limitations: work and employment constraints, recreation restrictions, limits on activities of daily living, reduced sexuality, concerns about housing and finances, and physical symptoms; 2) Restricted Social Interactions/Altered Social Networks: altered relationships with friends and family and reliance upon family and care givers; 3) Emotional Effects: reduced self-worth, vulnerability, depression, perseverance and adaptation, hopelessness, fear, pride, and lack of control; 4) Limitations in the Understanding of COPD: unawareness of diagnosis, triggers and reaction to disease manifestations, COPD management; and 5) Complex Healthcare Interactions. COPD pervasively and extensively affects all aspects of veterans' lives and causes significant consequences for their care and management. PMID:23537003

Content of health status reports of people seeking assisted suicide: a qualitative analysis.  

PubMed

Two right-to-die organisations offer assisted suicide in Switzerland. The specific legal situation allows assistance to Swiss and foreign citizens. Both organisations require a report of the person's health status before considering assistance. This qualitative study explored these reports filed to legal authorities after the deaths of individuals in the area of Zurich. Health status reports in the legal medical dossiers of the deceased were analysed using content analysis and Grounded Theory. From 421 cases of assisted suicide (2001-2004), 350 reports on health status were filed. Many cases contained diagnosis lists only. Other reports had more elaborate reports revealing that some physicians were aware about the patient's death wish and the intention to solicit assisted suicide. Physicians' attitudes ranged from neutral to rather depreciative. Few physicians openly referred the patient to the organisations and supported the patient's request by highlighting a history of suffering as well as reporting understanding and agreement with the patient's wish to hasten death. In the health status reports five categories could be identified. Some files revealed that physicians were aware of the death wish. The knowledge and recognition of the patient's death wish varied from no apparent awareness to strongly supportive. This variety might be due to difficulties to discuss the death wish with patients, but might also reflect the challenge to avoid legal prosecution in the country of origin. To require comparable health status reports as requirements for the right-to-die organisations might be difficult to pursue. PMID:21246400

Qualitative and quantitative analysis of surface-acoustic-wave-based ultraviolet photodetectors  

NASA Astrophysics Data System (ADS)

Surface-acoustic-wave (SAW) based ultraviolet (UV) photodetectors with multiple optical sensing areas is presented by depositing patterned ZnO films on a LiNbO3 substrate. Two different types of electrodes, uniform interdigital transducer (IDT) and slanted finger interdigital transducer (SFIT), are designed and fabricated to analyze the performances of SAW array UV photodetectors. By tuning ultraviolet wavelengths, qualitative characteristics of SAW UV photodetectors are observed through the measurements of SAW attenuation. Quantitative analyses of the photodetectors are presented by varying light intensities. Moreover, dynamic responses of SAW array UV photodetectors under the illumination of different optical wavelengths are also demonstrated. Ultraviolet light of 350 nm with power densities of 8.46 and 18.34 ?W/cm2 is detectable from a UV photodetector with uniform IDT and SFIT, respectively. This study not only indicates that a SAW-based UV sensor is a potential candidate of array UV photodetectors but also provides a comprehensive analysis of SAW UV photodetectors.

Qualitative analysis of Pb liquid sample using laser-induced breakdown spectroscopy (LIBS)  

NASA Astrophysics Data System (ADS)

Qualitative analysis of liquid sample containing 1,000 ppm of Pb was performed by using LIBS technique. In order to avoid splashing off of the liquid sample during laser irradiation, a sample pretreatment was done, namely the liquid sample was absorbed by using commercial available stomach medicine. Two kinds of absorbent materials were chosen in this experiment, first containing 125 mg activated carbon and second 600 mg activated attapulgite. These absorbent materials were used since carbon sample gives better absorption of infrared laser irradiation used in this experiment. In order to characterize the absorption process, three treatments were conducted in this experiment; first, without heating the sample but varying the absorption time before laser irradiation; second by varying the heating temperature after certain time of absorption process and third by varying the temperature only. The maximum emission intensity of Pb I 405.7 nm was found in the second treatment of heating the sample till 85°C after 30 minutes absorption of the liquid sample in both absorbent materials.

Qualitative analysis of macro-environmental factors affecting soil venting efficiency  

SciTech Connect

The efficiency of any soil vapor extraction operation has always been related to micro-environmental factors such as vapor flow rate, vapor flow path, and contaminant distribution and composition. However, it is not clear to what extent macroenvironmental factors such as barometric pressure, rainfall, temperature, and water table affect the operation of soil venting systems. The majority of research conducted to this date involves short term tests (less than one week), and the analysis assumes that the macro-environmental factors are constant over time. To assess the importance of macro-environmental factors, long term tests are necessary. Field tests using air extraction in vertical wells are evaluated in conjunction with the macro-environmental factors. Seven venting wells were installed at an uncontaminated sandy site. An automatic data acquisition system was set up to record the change of those macro-environmental factors and the pressures in the venting wells. The primary method of this qualitative study is to conduct long term tests (weeks or months duration) such that the effect of the environmental change can be characterized during the test.

Perceptions of heatwave risks to health: results of an qualitative interview study with older people and their carers in Freiburg, Germany.  

PubMed

Aims and objectives: Heatwaves can pose a severe threat to health, especially to older people. However, warnings do not necessarily lead to preventive action. This study aims at exploring individual risk perception and adaptive measures of older people and their carers. Their views are explored, taking into account personal backgrounds. Methods: Questionnaire-based interviews were administered to 20 men and women (64-94 years, living in their own homes or nursing homes) and 13 carers. A qualitative analysis following a framework approach was performed. Results: The majority of respondents stated that older people might be compromised by heatwaves; however, a large proportion of respondents saw themselves as less affected than the average population. Most respondents adopted preventive measures during heatwaves and a majority received warnings or pieces of information. The role of general practitioners in direct warning situations was judged controversial. Survey respondents displayed resistance to the use of technical devices to monitor potentially dangerous situations. In addition, the results support many previous findings. In particular, the relative concepts of ageing, variety of information channels used, and control orientations could be confirmed. Conclusions: General practitioners hold a position of trust and play a central role in the promotion of preventive action, but there are also limitations to their outreach. Many respondents could be classified as socially active, which has implications for preventive information campaigns. Information campaigns using different channels and targeting a larger audience should be considered. The degree of information of carers can partly be improved. PMID:23082104

Effect of Households' Social Networks on Lice Infestation among Vulnerable Mexican Children: a Qualitative Comparative Analysis.  

PubMed

The prevalence of pediculosis is high among elementary and secondary school children, which favors the belief that infestation occurs more often in schools than in homes. This study explored the role of households' social networks in the transmission of head lice. Seventeen school children and their social networks (n = 22) from Acatlipa (Morelos, Mexico) participated in a prospective observational study during school vacation. The hair of all the school children was washed with shampoo containing permethrin at the beginning of the study and the incidence of pediculosis (O) was evaluated at the beginning of the school term (follow-up at 1.5 months). The sets included in the qualitative comparative analysis were sex (S), length of hair (H), baseline diagnostic of pediculosis (I) and degree (D) and infestation index (N) obtained through the analysis of social networks. The prevalence of pediculosis was the same at the beginning and the end of follow-up (17.6%). The degree of the school children's networks ranged between 2 and 14. There were 8 configurations, the most frequent being F*i*d*n*h. The most parsimonious configuration associated with the incidence of pediculosis was F*I*d*H (female, previous infestation, low degree and long hair), with a coverage of 0.344 and a consistency of 0.941. Indicators of social networks made it possible to identify the role of households' social networks in the transmission of lice. Individual actions such as the use of shampoo containing insecticides are temporary and, therefore, structural actions should be favored. PMID:23751254

A Qualitative Meta-Analysis Reveals Consistent Effects of Atrazine on Freshwater Fish and Amphibians  

PubMed Central

Objective The biological effects of the herbicide atrazine on freshwater vertebrates are highly controversial. In an effort to resolve the controversy, we conducted a qualitative meta-analysis on the effects of ecologically relevant atrazine concentrations on amphibian and fish survival, behavior, metamorphic traits, infections, and immune, endocrine, and reproductive systems. Data sources We used published, peer-reviewed research and applied strict quality criteria for inclusion of studies in the meta-analysis. Data synthesis We found little evidence that atrazine consistently caused direct mortality of fish or amphibians, but we found evidence that it can have indirect and sublethal effects. The relationship between atrazine concentration and timing of amphibian metamorphosis was regularly nonmonotonic, indicating that atrazine can both accelerate and delay metamorphosis. Atrazine reduced size at or near metamorphosis in 15 of 17 studies and 14 of 14 species. Atrazine elevated amphibian and fish activity in 12 of 13 studies, reduced antipredator behaviors in 6 of 7 studies, and reduced olfactory abilities for fish but not for amphibians. Atrazine was associated with a reduction in 33 of 43 immune function end points and with an increase in 13 of 16 infection end points. Atrazine altered at least one aspect of gonadal morphology in 7 of 10 studies and consistently affected gonadal function, altering spermatogenesis in 2 of 2 studies and sex hormone concentrations in 6 of 7 studies. Atrazine did not affect vitellogenin in 5 studies and increased aromatase in only 1 of 6 studies. Effects of atrazine on fish and amphibian reproductive success, sex ratios, gene frequencies, populations, and communities remain uncertain. Conclusions Although there is much left to learn about the effects of atrazine, we identified several consistent effects of atrazine that must be weighed against any of its benefits and the costs and benefits of alternatives to atrazine use.

Manufacturing quality from electronic failure analysis results  

NASA Astrophysics Data System (ADS)

The Electronic Failure Analysis Group of the AFWAL/Materials Laboratory Systems Support Division has investigated numerous electronic device failures that resulted from manufacturing process defects. The electronic failure analysis program that verifies the device failure, locates the failure site, establishes the cause of failure and recommends corrective actions is discussed in relation to improving the quality of electronic devices; performing electronic failure analysis is a high-payoff activity. Corrective actions usually involve very small costs to the manufacturer and provide the user with a large return on investment. Brief case histories are presented in regard to packaging, die attachment, solder flux removal, package moisture content, IC metallization processes, potted modules, and handling procedures affecting device cleanliness. Situations are identified where better quality control could eliminate many device defects that lead to premature part failure.

Facilitators and barriers for eating behaviour changes in obstructive sleep apnoea and obesity - a qualitative content analysis.  

PubMed

Abstract Purpose: Obesity is a major risk factor for obstructive sleep apnoea syndrome, a condition known causing lack of sleep continuity and daytime sleepiness. Weight loss interventions are recommended, however knowledge on what facilitate and impede eating behaviour change is lacking for this particular population. The aim of this study was to identify personal conceptions of prerequisites for eating behaviour change. Method: A qualitative study on 15 patients with obstructive sleep apnoea syndrome (OSAS; apnoea-hypopnoea index >15) and obesity (Mean body mass index 38.2). Semi-structured interviews were conducted and data were transcribed and analysed using qualitative content analysis with researcher triangulation for trustworthiness. Results: Data were organised according to barriers and facilitators for changing eating behaviour. Identified barriers were desire and reward, cravings and emotional control, low self-confidence, insufficient support, taxing behaviours, cost, lack of knowledge about healthy eating strategies, perceived helplessness and low susceptibility. Identified facilitators were positive expectations, fear of negative consequences, experience of success, support and follow-up, accessibility, applied skills for healthy eating, personal involvement and challenged self-image. Conclusion: This study adds knowledge on important barriers and facilitators of eating behaviour change according to individuals with obesity and OSAS. Information used to inform a tailored behavioural medicine intervention targeting eating behaviours. Implications for Rehabilitation Patients with obstructive sleep apnoea syndrome (OSAS) benefit from weight loss and eating behaviour changes are recommended. Patients' views on prerequisites for eating behaviour change are important to plan, conduct and tailor behaviour change interventions. These aspects have hitherto not been elaborated in patients with OSAS. Considerations on patient's self-image and perceived susceptibility along with providing strategies for controlling the desire and rewarding feeling associated with eating are emphasised.

While the literature on male sex work has increased significantly over the past decade, few studies examine the influence of relational dynamics in the lives of those engaged in male sex work. This qualitative study, conducted with a sample of male street sex workers in Sydney, Australia, explores how relationships color their involvement with sex work. The findings reveal the complexity of their relationships and how their interactions with others shape their engagement in sex work. The data also offer insight into how exit pathways are influenced by money and relationships that occur within this particular male sex work setting. Implications for health policy and intervention are considered. PMID:18019070

A qualitative analysis of the elements used by palliative care clinicians when formulating a survival estimate  

PubMed Central

Objective For patients with advanced and/or incurable disease, clinicians are often called upon to formulate and communicate an estimate of likely survival duration. The objective of this study was to gain a deeper appreciation of this process by identifying and exploring the specific elements that may inform and/or impact a clinician's estimate of survival (CES). Methods Semistructured interviews were conducted among a group of palliative care clinicians in the setting of a tertiary academic health sciences centre. Qualitative data were subsequently analysed using a grounded theory approach. Results Five major themes were identified as being central to the process of CES formulation: use of objective patient-specific elements, strength of the patient-clinician relationship, purpose and context of an individual CES, perceived role of hope and the overall likelihood of CES inaccuracy. Conclusions For any given patient, several elements have the potential to inform and/or impact the process of CES formulation. Study participants were aware of objective clinical factors known to correlate with actual survival duration and likely integrate this information when formulating a CES. Formulation occurs within a larger context comprised of a number of elements that may influence individual estimates. These elements exist against a background of awareness of the overall likelihood of CES inaccuracy. Clinicians are encouraged to develop a personalised and standardised approach to CES formulation whereby an awareness of the menu of potentially impacting elements is consciously integrated into an individual process.

Complex mixture analysis using protein expression as a qualitative and quantitative tool  

SciTech Connect

Some proteins in organisms exposed to chemicals in stressful amounts or toxic concentrations show increased expression; others show decreased expression. These inducible and repressible proteins together potentially provide qualitative and quantitative diagnoses of components in complex mixtures of chemicals. The authors examined sets of proteins synthesized by Daphnia magna after exposure to mixtures of a cationic polyamide epichlorhydrin adduct (Kymene) and a combined assortment of water-extractable substances from chemi-thermal-mechanical pulp (CTMP) in lab water. Proteins were identified, after extracting from Daphnia magna, by gel filtration and silver staining, or by radiolabeling and then gel separation. Patterns of proteins induced by Kymene[reg sign] and by CTMP extracts were distinguishable in lab water, but there was interaction between them. The method of identifying and quantifying Kymene, however, was successful using lab simulations of mixtures. The method was tested using wastewater samples from a paper manufacturing plant. Kymene could be detected against variable levels and types of additional substances. But, again, there was interference, perhaps due to Kymene binding to other anionic polymers sometimes present in the samples. Interpretation from analyses of protein expression were consistent with results from sublethal Ceriodaphnia dubia assays.

Qualitative analysis of Brans-Dicke universes with a cosmological constant  

SciTech Connect

Solutions to flat space Friedmann-Robertson-Walker cosmologies in Brans-Dicke theory with a cosmological constant are investigated. The matter is modeled as a {gamma}-law perfect fluid. The field equations are reduced from fourth order to second order through a change of variables, and the resulting two-dimensional system is analyzed using dynamical system theory. When the Brans-Dicke coupling constant is positive ({omega}>0), all initially expanding models approach exponential expansion at late times, regardless of the type of matter present. If ({omega} < 0), then a wide variety of qualitatively distinct models are present, including nonsingular {open_quotes}bounce{close_quotes} universes, {open_quotes}vacillating{close_quotes} universes, and, in the special case of {omega} = -1, models which approach stable Minkowski spacetime with an exponentially increasing scalar field at late times. Since power-law solutions do not exist, none of the models appears to offer any advantage over the standard deSitter solution of general relativity in achieving a graceful exit from inflation. 17 refs., 4 figs., 2 tabs.

Current (re-)Distribution inside an ITER Full-Size Conductor: a Qualitative Analysis  

NASA Astrophysics Data System (ADS)

The comprehension of the current re-distribution phenomenon inside multi-filamentary conductors is a crucial point for the design of ITER-relevant coils, as it is by now assessed that current non-uniformity among cable sub-stages may strongly deteriorate Cable-in-Conduit Conductors (CICC) performances. The only feasible way to get information about the current flowing inside CICC sub-stages is an indirect evaluation by self-field measurements in regions very close to conductor surface. A 7m full-size NbTi conductor (Bus-Bar III) has been used as short-circuit during the test of an ITER Toroidal Field Coil HTS current lead at FzK. Its relatively simple shape and the absence of any other magnetic field source (background coils, etc.), made BBIII one of the most desirable candidate for a reliable measurement of the current distribution under controlled conditions. This is why it has been ad hoc instrumented with different arrangements of Hall-probes (rings and arrays), as well as with transverse and longitudinal voltage taps. This paper gives a qualitative interpretation of the current (re-)distribution events inside the conductor as derived from the analysis of the Hall sensors and the voltage taps signals, during Tcs measurements and as a function of different dI/dt. It has been shown that Hall probes represent a very reliable tool to investigate this issue. In fact, re-distribution phenomena have been clearly observed during transition, and even far before reaching Tcs, when voltage transverse signals had not yet showed any appreciable onset.

Hypertension management initiative: qualitative results from implementing clinical practice guidelines in primary care through a facilitated practice program.  

PubMed

The goal of the Hypertension Management Initiative (HMI) is to improve the management and control of hypertension by both primary care providers and patients. The HMI was in effect in 11 primary care sites across the province of Ontario, Canada. This was a qualitative study. Focus groups and a lobby survey were completed with a total of 199 of the 3934 patients enrolled in the study. Interviews with 41 participating health care providers from all sites were performed. A qualitative description approach was used to give a rich description of each informant's experiences. Patients expressed motivation and engagement in their own health care and became more knowledgeable about hypertension and how to manage it with their health care providers. Most reported satisfaction with the discipline of regular appointments and ongoing monitoring and counseling of the program including identifying and working on goals for their modifiable risk factors. Their health care providers felt the HMI program had a positive impact on the treatment and management of hypertension and also that it improved the functioning of the interprofessional team. The HMI helped to improve patient self-empowerment and self-management and also improved physicians' and nurses' confidence in diagnosing accurately and in hypertension management. Physician buy-in is key to maintaining clinical hypertension management. Interprofessional collaboration was improved for physicians and nurses but less so for pharmacists. Greater confidence among the nurses to manage hypertension more independently reduced demands on physician time. PMID:23523109

Life impact of ankle fractures: Qualitative analysis of patient and clinician experiences  

PubMed Central

Background Ankle fractures are one of the more commonly occurring forms of trauma managed by orthopaedic teams worldwide. The impacts of these injuries are not restricted to pain and disability caused at the time of the incident, but may also result in long term physical, psychological, and social consequences. There are currently no ankle fracture specific patient-reported outcome measures with a robust content foundation. This investigation aimed to develop a thematic conceptual framework of life impacts following ankle fracture from the experiences of people who have suffered ankle fractures as well as the health professionals who treat them. Methods A qualitative investigation was undertaken using in-depth semi-structured interviews with people (n=12) who had previously sustained an ankle fracture (patients) and health professionals (n=6) that treat people with ankle fractures. Interviews were audio-recorded and transcribed. Each phrase was individually coded and grouped in categories and aligned under emerging themes by two independent researchers. Results Saturation occurred after 10 in-depth patient interviews. Time since injury for patients ranged from 6 weeks to more than 2 years. Experience of health professionals ranged from 1 year to 16 years working with people with ankle fractures. Health professionals included an Orthopaedic surgeon (1), physiotherapists (3), a podiatrist (1) and an occupational therapist (1). The emerging framework derived from patient data included eight themes (Physical, Psychological, Daily Living, Social, Occupational and Domestic, Financial, Aesthetic and Medication Taking). Health professional responses did not reveal any additional themes, but tended to focus on physical and occupational themes. Conclusions The nature of life impact following ankle fractures can extend beyond short term pain and discomfort into many areas of life. The findings from this research have provided an empirically derived framework from which a condition-specific patient-reported outcome measure can be developed.

A Qualitative Analysis of Career Transitions Made by Internal Medicine-Pediatrics Residency Training Graduates  

PubMed Central

BACKGROUND Physicians who complete combined residency training in internal medicine and pediatrics (med-peds) have a variety of career options after training. Little is known about career transitions among this group or among other broadly trained physicians. METHODS To better understand these career transitions, we conducted semistructured, in-depth, telephone interviews of graduates of the University of North Carolina–Chapel Hill School of Medicine med-peds program who self-identified as having had a career transition since completing training. We qualitatively analyzed interview transcripts, to develop themes describing their career transitions. RESULTS Of 106 physicians who graduated during 1980–2007, 20 participated in interviews. Participants identified factors such as personality, work environment, lifestyle, family, and finances as important to career transition. Five other themes emerged from the data; the following 4 were confirmed by follow-up interviews: (1) experiences during residency were not sufficient to predict future job satisfaction; work after the completion of training was necessary to discover career preferences; (2) a major factor motivating job change was a perceived lack of control in the workplace; (3) participants described a sense of regret if they did not continue to see both adult and pediatric patients as a result of their career change; (4) participants appreciated their broad training and, regardless of career path, would choose to pursue combined residency training again. LIMITATIONS We included only a small number of graduates from a single institution. We did not interview graduates who had no career transitions after training. CONCLUSIONS There are many professional opportunities for physicians trained in med-peds. Four consistent themes surfaced during interviews about med-peds career transitions. Future research should explore how to use these themes to help physicians make career choices and employers retain physicians.

Recent advances on multidimensional liquid chromatography-mass spectrometry for proteomics: from qualitative to quantitative analysis--a review.  

PubMed

With the acceleration of proteome research, increasing attention has been paid to multidimensional liquid chromatography-mass spectrometry (MDLC-MS) due to its high peak capacity and separation efficiency. Recently, many efforts have been put to improve MDLC-based strategies including "top-down" and "bottom-up" to enable highly sensitive qualitative and quantitative analysis of proteins, as well as accelerate the whole analytical procedure. Integrated platforms with combination of sample pretreatment, multidimensional separations and identification were also developed to achieve high throughput and sensitive detection of proteomes, facilitating highly accurate and reproducible quantification. This review summarized the recent advances of such techniques and their applications in qualitative and quantitative analysis of proteomes. PMID:22652259

Towards an empowerment approach in tuberculosis treatment in Cape Town, South Africa: a qualitative analysis of programmatic change  

PubMed Central

Background Tuberculosis rates in the world remain high, especially in low- and middle-income countries. International tuberculosis (TB) policy generally recommends the use of directly observed therapy (DOT) to ensure treatment adherence. Objective This article examines a change in TB treatment support that occurred in 2005 in South Africa, from DOT to the enhanced TB adherence programme (ETA). Design Seven key individuals representing academics, policy makers and service providers involved in the development of the ETA programme or knowledgeable about the issue were purposively sampled and interviewed, and participant observation was conducted at ETA programme steering group meetings. Qualitative content analysis was used to analyse the data, drawing on the Kingdon model of agenda setting. This model suggests that three independent streams – problem, policy and politics – come together at a certain point, often facilitated by policy entrepreneurs, to provide an opportunity for an issue to enter the policy agenda. Results The results suggest the empowerment-oriented programme emerged through the presence of policy entrepreneurs with access to resources. Policy entrepreneurs were influenced by a number of simultaneously occurring challenges including problems within the existing programme; a perceived mismatch between patient needs and the existing TB treatment model; and the TB-HIV co-epidemic. Policy entrepreneurs saw the ART approach as a possible solution to these challenges. Conclusions The Kingdon model contributed to describing the process of policy change. Research evidence seemed to influence this change diffusely, through the interaction of policy entrepreneurs and academics.

Who should decide? Qualitative analysis of panel data from public, patients, healthcare professionals, and insurers on priorities in health care.  

PubMed Central

OBJECTIVE: To explore the arguments underlying the choices of patients, the public, general practitioners, specialists, and health insurers regarding priorities in health care. DESIGN: A qualitative analysis of data gathered in a series of panels. Members were asked to economise on the publicly funded healthcare budget, exemplified by 10 services. RESULTS: From a medical point of view, both panels of healthcare professionals thought most services were necessary. The general practitioners tried to achieve the budget cuts by limiting access to services to those most in need of them or those who cannot afford to pay for them. The specialists emphasised the possibilities of reducing costs by increasing the efficiency within services and preventing inappropriate utilisation. The patients mainly economised by limiting universal access to preventive and acute services. The "public" panels excluded services that are relatively inexpensive for individual patients. Moreover, they emphasised the individual's own responsibility for health behaviour and the costs of health care, resulting in the choice for copayments. The health insurers emphasised the importance of including services that relate to a risk only, as well as feasibility aspects. CONCLUSIONS: There were substantial differences in the way the different groups approached the issue of what should be included in the basic package. Healthcare professionals seem to be most aware of the importance of maintaining equal access for everyone in need of health care.

Influences of organizational features of healthcare settings on clinical decision making: Qualitative results from a cross-national factorial experiment*  

PubMed Central

A proliferating literature documents cross-national variation in medical practice and seeks to explain observed differences in terms of the presence of certain kinds of healthcare systems, economic, and cultural differences between countries. Less is known about how providers themselves understand these influences and perceive them as relevant to their clinical work. Using qualitative data from a cross-national factorial experiment in the United States and United Kingdom, we analyze 244 primary care physicians’ explanations of how organizational features of their respective healthcare settings influence the treatment decisions they made for a vignette patient, including affordability of care; within-system quality deficits; and constraints due to patient behavior. While many differences are attributed to financial constraints deriving from two very differently structured healthcare systems, in other ways they are reflections of cultural and historical expectations regarding medical care, or interactions between the two. Implications, including possible challenges to the implementation of universal care in the US, are discussed.

Conflicts and conflict regulation in hospices: nurses' perspectives : Results of a qualitative study in three German hospices.  

PubMed

The present article considers conflicts and conflict regulation in hospices. The authors carried out a qualitative study in three hospices in North Rhine-Westphalia, Germany, to explore how conflicts arise and how conflict regulation proceeds. Hospice nurses should act according to a set of ethical codes, to mission statements of the institution and to professional standards of care. In practice the subjective interpretations of codes and/or models concerning questions of care are causes of conflicts among nurses, with doctors, patients and family members. The management has two choices to react to these conflicts. It can either tolerate the conflicts, as long as they do not disturb the daily routine. Or it can increase the degree of organisation by integrating the different viewpoints into its own program and/or by restructuring its organisational units. PMID:23264046

Primary care nurses struggle with lifestyle counseling in diabetes care: a qualitative analysis  

PubMed Central

Background Patient outcomes are poorly affected by lifestyle advice in general practice. Promoting lifestyle behavior change require that nurses shift from simple advice giving to a more counseling-based approach. The current study examines which barriers nurses encounter in lifestyle counseling to patients with type 2 diabetes. Based on this information we will develop an implementation strategy to improve lifestyle behavior change in general practice. Method In a qualitative semi-structured study, twelve in-depth interviews took place with nurses in Dutch general practices involved in diabetes care. Specific barriers in counseling patients with type 2 diabetes about diet, physical activity, and smoking cessation were addressed. The nurses were invited to reflect on barriers at the patient and practice levels, but mainly on their own roles as counselors. All interviews were audio-recorded and transcribed. The data were analyzed with the aid of a predetermined framework. Results Nurses felt most barriers on the level of the patient; patients had limited knowledge of a healthy lifestyle and limited insight into their own behavior, and they lacked the motivation to modify their lifestyles or the discipline to maintain an improved lifestyle. Furthermore, nurses reported lack of counseling skills and insufficient time as barriers in effective lifestyle counseling. Conclusions The traditional health education approach is still predominant in primary care of patients with type 2 diabetes. An implementation strategy based on motivational interviewing can help to overcome 'jumping ahead of the patient' and promotes skills in lifestyle behavioral change. We will train our nurses in agenda setting to structure the consultation based on prioritizing the behavior change and will help them to develop social maps that contain information on local exercise programs.

Developmental Challenges, Stressors, and Coping in Medical Residents: A Qualitative Analysis of Support Groups  

PubMed Central

Introduction Stress and burnout are endemic to post-graduate medical training but little research is available to guide supportive interventions. The identification of longitudinal emotional and developmental coping needs of internal medicine residents could assist in better designing and implementing supportive interventions. Methods In this retrospective, exploratory study, six internal medicine resident support groups (n = 62 PGY1-3 residents) were followed for a period of two years. Qualitative data were extracted from monthly support group process notes to identify common themes, stressors, emotions, coping strategies, and developmental challenges faced during training. Quantitative questionnaire data were collected on burnout, group attendance, and resident satisfaction. Results Using professional identity development models and classic stress and coping theory as a starting point, a derivation of Grounded Theory was used to identify common themes and emotions contained in support group process notes. The most common themes included understanding resident roles and responsibilities, developing an identity as a resident and physician, building professional confidence, cognitive and behavioral responses to stress, and concerns about flaws in local and national health care training and delivery systems. Anxiety and guilt were the most commonly reported emotions, followed by positive emotions and anger. Burnout scores were highest for the second half of the PGY1 year, but improved over subsequent training years. Support group attendance and satisfaction were both high. Residents overwhelmingly pointed to peer relationships as the most critical source of support throughout postgraduate training. Conclusions Developmentally-informed programmatic adaptations could better support the emotional growth and personal/professional development of postgraduate medical trainees. Future directions should include a controlled trial of resident support groups, assessments of “active ingredients” (i.e. what supportive interventions are most effective), and/or evaluations of programmatic adaptations.

Geothermal industry employment: Survey results & analysis  

SciTech Connect

The Geothermal Energy Association (GEA) is ofteh asked about the socioeconomic and employment impact of the industry. Since available literature dealing with employment involved in the geothermal sector appeared relatively outdated, unduly focused on certain activities of the industry (e.g. operation and maintenance of geothermal power plants) or poorly reliable, GEA, in consultation with the DOE, decided to conduct a new employment survey to provide better answers to these questions. The main objective of this survey is to assess and characterize the current workforce involved in geothermal activities in the US. Several initiatives have therefore been undertaken to reach as many organizations involved in geothermal activities as possible and assess their current workforce. The first section of this document describes the methodology used to contact the companies involved in the geothermal sector. The second section presents the survey results and analyzes them. This analysis includes two major parts. The first part analyzes the survey responses, presents employment numbers that were captured and describes the major characteristics of the industry that have been identified. The second part of the analysis estimates the number of workers involved in companies that are active in the geothermal business but did not respond to the survey or could not be reached. Preliminary conclusions and the study limits and restrictions are then presented. The third section addresses the potential employment impact related to manufacturing and construction of new geothermal power facilities. Indirect and induced economic impacts related with such investment are also investigated.

Feeling labeled, judged, lectured, and rejected by family and friends over depression: Cautionary results for primary care clinicians from a multi-centered, qualitative study  

PubMed Central

Background Family and friends may help patients seek out and engage in depression care. However, patients’ social networks can also undermine depression treatment and recovery. In an effort to improve depression care in primary care settings, we sought to identify, categorize, and alert primary care clinicians to depression-related messages that patients hear from friends and family that patients perceive as unhelpful or detrimental. Methods We conducted 15 focus groups in 3 cities. Participants (n?=?116) with a personal history or knowledge of depression responded to open-ended questions about depression, including self-perceived barriers to care-seeking. Focus group conversations were audio-recorded and analyzed using iterative qualitative analysis. Results Four themes emerged related to negatively-received depression messages delivered by family and friends. Specifically, participants perceived these messages as making them feel labeled, judged, lectured to, and rejected by family and friends when discussing depression. Some participants also expressed their interpretation of their families’ motivations for delivering the messages and described how hearing these messages affected depression care. Conclusions The richness of our results reflects the complexity of communication within depression sufferers’ social networks around this stigmatized issue. To leverage patients’ social support networks effectively in depression care, primary care clinicians should be aware of both the potentially beneficial and detrimental aspects of social support. Specifically, clinicians should consider using open-ended queries into patients’ experiences with discussing depression with family and friends as an initial step in the process. An open-ended approach may avoid future emotional trauma or stigmatization and assist patients in overcoming self-imposed barriers to depression discussion, symptom disclosure, treatment adherence and follow-up care.

Linking Data to Decision-Making: Applying Qualitative Data Analysis Methods and Software to Identify Mechanisms for Using Outcomes Data  

PubMed Central

A multiple case study was conducted to examine how staff in child out-of-home care programs used data from an Outcomes Management System (OMS) and other sources to inform decision-making. Data collection consisted of thirty-seven semi-structured interviews with clinicians, managers, and directors from two treatment foster care programs and two residential treatment centers, and individuals involved with developing the OMS; and observations of clinical and quality management meetings. Case study and grounded theory methodology guided analyses. The application of qualitative data analysis software is described. Results show that although staff rarely used data from the OMS, they did rely on other sources of systematically collected information to inform clinical, quality management, and program decisions. Analyses of how staff used these data suggest that improving the utility of OMS will involve encouraging staff to participate in data-based decision-making, and designing and implementing OMS in a manner that reflects how decision-making processes operate.

Could We Have Known? A Qualitative Analysis of Data from Women Who Survived an Attempted Homicide by an Intimate Partner  

PubMed Central

OBJECTIVE To examine in-depth the lives of women whose partners attempted to kill them, and to identify patterns that may aid in the clinician's ability to predict, prevent, or counsel about femicide or attempted femicide. DESIGN Qualitative analysis of 30 in-depth interviews. SETTING Six U.S. cities. PARTICIPANTS Thirty women, aged 17–54 years, who survived an attempted homicide by an intimate partner. RESULTS All but 2 of the participants had previously experienced physical violence, controlling behavior, or both from the partner who attempted to kill them. The intensity of the violence, control, and threats varied greatly, as did the number of risk factors measured by the Danger Assessment, defining a wide spectrum of prior abuse. Approximately half (14/30) of the participants did not recognize that their lives were in danger. Women often focused more on relationship problems involving money, alcohol, drugs, possessiveness, or infidelity, than on the risk to themselves from the violence. The majority of the attempts (22/30) happened around the time of a relationship change, but the relationship was often ending because of problems other than violence. CONCLUSIONS Clinicians should not be falsely reassured by a woman's sense of safety, by the lack of a history of severe violence, or by the presence of few classic risk factors for homicide. Efforts to reduce femicide risk that are targeted only at those women seeking help for violence-related problems may miss potential victims.

Background The Veterans Health Administration (VA) has invested significant resources in designing and implementing a comprehensive electronic health record (EHR) that supports clinical priorities. EHRs in general have been difficult to implement, with unclear cost-effectiveness. We describe VA clinical personnel interactions with and evaluations of the EHR. Methods As part of an evaluation of a quality improvement initiative, we interviewed 72 VA clinicians and managers using a semi-structured interview format. We conducted a qualitative analysis of interview transcripts, examining themes relating to participants' interactions with and evaluations of the VA EHR. Results Participants described their perceptions of the positive and negative effects of the EHR on their clinical workflow. Although they appreciated the speed and ease of documentation that the EHR afforded, they were concerned about the time cost of using the technology and the technology's potential for detracting from interpersonal interactions. Conclusions VA personnel value EHRs' contributions to supporting communication, education, and documentation. However, participants are concerned about EHRs' potential interference with other important aspects of healthcare, such as time for clinical care and interpersonal communication with patients and colleagues. We propose that initial implementation of an EHR is one step in an iterative process of ongoing quality improvement.

Fluorescence lifetime selectivity in excitation-emission matrices for qualitative analysis of a two-component system  

SciTech Connect

Steady-state fluorescence excitation-emission matrices (EEMs), and phase-resolved EEMs (PREEMs) collected at modulation frequencies of 6, 18, and 30 MHz, were used for qualitative analysis of mixtures of benzo(k)fluoranthene ({tau} = 8 ns) and benzo(b)fluoranthene ({tau} = 29 ns) in ethanol. The EEMs of the individual components were extracted from mixture EEMs by means of wavelength component vector-gram (WCV) analysis. Phase resolution was found to be superior to steady-state measurements for extraction of the component spectra, for mixtures in which the intensity contributions from the two components are unequal.

Device-oriented qualitative reasoning for dynamic physical systems  

SciTech Connect

There are few tools to assist the engineer in the initial phase of a design and analysis of a dynamic system. This paper illustrates the utility of a device-oriented qualitative reasoning system as a tool for generating generalized system behavior information which is invaluable information to the designer. For the first time, a qualitative model is presented in terms of its underlying continuous representation. A phase plane analysis, an analysis tool which can only be automated if specific parameter information is defined, is presented for the continuous representation and a qualitative analysis is presented for the qualitative model. The phase plane and state transition diagram, the result of the qualitative analysis, are shown to capture equivalent information. This comparison highlights the ability of qualitative reasoning techniques to provide an automated approach to deriving general system behavior in the absence of specific parameter information. 9 refs., 5 figs., 5 tabs.

A qualitative analysis of general receptive vocabulary of adolescents with Down syndrome.  

PubMed

This study aimed to discover whether general receptive vocabulary is qualitatively phenotypical in Down syndrome. Sixty-two participants with Down syndrome (M age=16.74 years, SD=3.28) were individually matched on general vocabulary raw total score with 62 participants with intellectual disability of undifferentiated etiology (M age=16.20 years, SD=3.08) and 62 typical children (M age=5.32 years, SD=0.82). Item analyses using the transformed item difficulties method to detect differential item functioning across groups showed that the groups' rank orders of item difficulty were highly similar. It was concluded that the general receptive vocabulary of older children and adolescents with Down syndrome is not qualitatively distinguished when its overall size is held constant. Methodological and theoretical implications of this finding are discussed. PMID:22716266

Qualitative and quantitative analysis in systematic dialectics: Marx vs. Hegel and Arthur vs. Smith  

Microsoft Academic Search

Whether capitalism is best studied using qualitative or quantitative methods is a standing issue. A key determinant in answering this is whether numerical measures can be meaningfully imposed on it epistemologically or even be said to constitute it ontologically. Reflecting on Smith’s and Arthur’s accounts of Hegel’s influence on Marx, it is concluded that both caveats are true for capitalism.

Results and analysis of the GLONASS measurements  

NASA Astrophysics Data System (ADS)

With the purpose of improving the national geodetic reference frame an establishment of the new Fundamental Astro-Geodetic network (FAGN), based mainly on the combined use of GPS and GLONASS measurements, is now carried out in Russia. From the geodetic point of view, the advantages of combining both systems are numerous, especially in the urban, mountain and near polar areas. More than 30 permanent core sites of this network are provided with the dual GPS/GLONASS receivers. Several core sites of the FAGN network are collocated with the existing IERS stations, equipped with the SLR, VLBI and DORIS instruments. Now the constellation of the GLONASS consists of 24 satellites at three orbital planes, 8 satellites in each. Inclination of the orbit is 64.80, height 19100 km and revolution time 11h 15min. Analysis of the GLONASS data, obtained at the IGS sites, including most of the Russian sites, have been made with the use of GIPSY-OASIS 2 software. Results of estimation of GLONASS orbital parameters and station coordinates were compared with the GPS estimations at the collocated sites. Both solutions are related to the ITRF2005 coordinate system. Differences between solutions are in the limit of a few cm. The means of improvement of the GLONASS solution and adjustment of the GLONASS coordinate system with the ITRF are considered.

Assessment accommodations on tests of academic achievement for students who are deaf or hard of hearing: a qualitative meta-analysis of the research literature.  

PubMed

The authors conducted a qualitative meta-analysis of the research on assessment accommodations for students who are deaf or hard of hearing. There were 16 identified studies that analyzed the impact of factors related to student performance on academic assessments across different educational settings, content areas, and types of assessment accommodations. The meta-analysis found that the results of analyses of group effects of accommodated versus unaccommodated test formats are often not significant, test-level factors exist that can affect how students perceive the assessments, and differences exist in how test items function across different conditions. Student-level factors, including educational context and academic proficiency, influence accommodations' role in assessment processes. The results of this analysis highlight the complexity of and intersections between student-level factors, test-level factors, and larger policy contexts. Findings are discussed within the context of larger changes in academic assessment, including computer-based administration and high-stakes testing. PMID:24133960

Resilience of refugees displaced in the developing world: a qualitative analysis of strengths and struggles of urban refugees in Nepal  

PubMed Central

Background Mental health and psychosocial wellbeing are key concerns in displaced populations. Despite urban refugees constituting more than half of the world's refugees, minimal attention has been paid to their psychosocial wellbeing. The purpose of this study was to assess coping behaviour and aspects of resilience amongst refugees in Kathmandu, Nepal. Methods This study examined the experiences of 16 Pakistani and 8 Somali urban refugees in Kathmandu, Nepal through in-depth individual interviews, focus groups, and Photovoice methodology. Such qualitative approaches enabled us to broadly discuss themes such as personal experiences of being a refugee in Kathmandu, perceived causes of psychosocial distress, and strategies and resources for coping. Thematic network analysis was used in this study to systematically interpret and code the data. Results Our findings highlight that urban refugees' active coping efforts, notwithstanding significant adversity and resulting distress, are most frequently through primary relationships. Informed by Axel Honneth's theory on the struggle for recognition, findings suggest that coping is a function beyond the individual and involves the ability to negotiate recognition. This negotiation involves not only primary relationships, but also the legal order and other social networks such as family and friends. Honneth's work was used because of its emphasis on the importance of legal recognition and larger structural factors in facilitating daily coping. Conclusions Understanding how urban refugees cope by negotiating access to various forms of recognition in the absence of legal-recognition will enable organisations working with them to leverage such strengths and develop relevant programmes. In particular, building on these existing resources will lead to culturally compelling and sustainable care for these populations.

Being a qualitative researcher.  

PubMed

This article, from a keynote address, is the result of some of the things which I learned about qualitative research during my many years of doing and teaching it. The main point I make is that qualitative researchers should present a good story which is based on evidence but focused on meaning rather than measurement. In qualitative inquiry, the researchers' selves are involved, their experiences become a resource. Researchers cannot distance themselves from the other participants, although they cannot fully present their meaning and experience. I also discuss voice, paradigm, and innovation as potentially problematic issues in qualitative research. These are terms often used but not always examined for their meaning in qualitative inquiry. If researchers are aware and sensitive, rather than overemotional or self-absorbed, qualitative research can be enlightening, person-centered, and humanistic. PMID:21266705

Effect of mobile phase additives on qualitative and quantitative analysis of ginsenosides by liquid chromatography hybrid quadrupole-time of flight mass spectrometry.  

PubMed

This study was to systematically investigate the effect of mobile phase additives, including ammonia water, formic acid, acetic acid, ammonium chloride and water (as a control), on qualitative and quantitative analysis of fifteen representative ginsenosides based on liquid chromatography hybrid quadrupole-time of flight mass spectrometry (LC-Q-TOF/MS). To evaluate the influence of mobile phase additives on qualitative performance, the quality of the negative mode MS/MS spectra of ginsenosides produced by online LC-Q-TOF/MS analyses, particularly the numbers and intensities of fragment ions, were compared under different adduct ion states, and found to be strongly affected by the mobile phase additives. When 0.02% acetic acid was added in the mobile phase, the deprotonated ginsenosides ions produced the most abundant product ions, while almost no product ion was observed for the chlorinated ginsenoside ions when 0.1mM ammonium chloride was used as the mobile phase additive. On the other hand, sensitivity, linear range and precision were adopted to investigate the quantitative performance affected by different mobile phase additives. Validation results of the LC-Q-TOF/MS-based quantitative performance for ginsenosides showed that ammonium chloride not only provided the highest sensitivity for all the target analytes, but also dramatically improved the linear ranges, the intra-day and inter-day precisions comparing to the results obtained using other mobile phase additives. Importantly, the validated method, using 0.1mM ammonium chloride as the mobile phase additive, was successfully applied to the quantitative analysis of ginsenosides in rat plasma after intragastric administration of Ginsenoside Extract at 200mg/kg. In conclusion, 0.02% acetic acid was deemed to be the most suitable mobile phase additive for qualitative analysis of ginsenosides, and 0.1mM ammonium chloride in mobile phase could lead to the best quantitative performance. Our results reveal that choosing the appropriate mobile phase additive is an important step in optimizing the analytical conditions, and the best quantitative method may not be suitable for the qualitative analysis.

Public opinions toward social concerns are worth to be noticed for decision makers to undertake any policies and their outcomes. Social psychologists usually undertake a series of investigations to access the interaction underneath the common thinking or actions. The design and statistic processing of the questionnaires always require a lot of manpower.

Analysis of Water Conflicts across Natural and Societal Boundaries: Integration of Quantitative Modeling and Qualitative Reasoning  

NASA Astrophysics Data System (ADS)

Water issues and problems have bewildered humankind for a long time yet a systematic approach for understanding such issues remain elusive. This is partly because many water-related problems are framed from a contested terrain in which many actors (individuals, communities, businesses, NGOs, states, and countries) compete to protect their own and often conflicting interests. We argue that origin of many water problems may be understood as a dynamic consequence of competition, interconnections, and feedback among variables in the Natural and Societal Systems (NSSs). Within the natural system, we recognize that triple constraints on water- water quantity (Q), water quality (P), and ecosystem (E)- and their interdependencies and feedback may lead to conflicts. Such inherent and multifaceted constraints of the natural water system are exacerbated often at the societal boundaries. Within the societal system, interdependencies and feedback among values and norms (V), economy (C), and governance (G) interact in various ways to create intractable contextual differences. The observation that natural and societal systems are linked is not novel. Our argument here, however, is that rigid disciplinary boundaries between these two domains will not produce solutions to the water problems we are facing today. The knowledge needed to address water problems need to go beyond scientific assessment in which societal variables (C, G, and V) are treated as exogenous or largely ignored, and policy research that does not consider the impact of natural variables (E, P, and Q) and that coupling among them. Consequently, traditional quantitative methods alone are not appropriate to address the dynamics of water conflicts, because we cannot quantify the societal variables and the exact mathematical relationships among the variables are not fully known. On the other hand, conventional qualitative study in societal domain has mainly been in the form of individual case studies and therefore, the knowledge generated from these studies cannot be easily generalized or transferred to other basins. Here, we present an approach to integrate the quantitative and qualitative methods to study water issues and capture the contextual knowledge of water management- by combining the NSSs framework and an area of artificial intelligence called qualitative reasoning. Using the Apalachicola-Chattahoochee-Flint (ACF) River Basin dispute as an example, we demonstrate how quantitative modeling and qualitative reasoning can be integrated to examine the impact of over abstraction of water from the river on the ecosystem and the role of governance in shaping the evolution of the ACF water dispute.

Participant experiences from chronic administration of a multivitamin versus placebo on subjective health and wellbeing: a double-blind qualitative analysis of a randomised controlled trial  

PubMed Central

Background While many randomised controlled trials have been conducted on multivitamins, to our knowledge no qualitative research exploring the subjective experience of taking a multivitamin during a clinical trial has been reported. Methods Semi-structured and open-ended written questions were incorporated into a 16-week double-blind, randomised, placebo-controlled, parallel groups trial of once-daily multivitamin administration. At the final study visit (week 16), three open-ended questions were posed to elucidate any positive, negative or unusual experiences from taking either the multivitamin or matched placebo. Qualitative thematic analysis was undertaken by researchers who were blind as to treatment condition of participants, and triangulation (independent analysis from three researchers) was employed to ensure methodological rigour. Participant’s experiences were categorised as “positive” or “negative” and a Chi Square analysis was then applied to each of the experiential themes, to compare experiences between the multivitamin and placebo groups, (subdividing the groups by gender). Usual experiences were categorised and discussed separately. Results Of the 182 participants enrolled, 116 completed the study and qualitative data were available from 114 participants. Thematic analysis revealed significant effects in favour of the multivitamin over placebo for participants experiencing increased energy levels (p=.022) and enhanced mood (p=.027). The beneficial effect on energy levels was particularly evident among female participants. A trend was found for participants reporting better sleep in the multivitamin over placebo. The multivitamin and placebo groups did not significantly differ in perceived positive or negative effects in areas relating to other aspects of mental function or physical health. No significant negative effects were revealed, although there was a non-significant trend for more people in the multivitamin group having minor digestive complaints. Conclusion This represents the first documented qualitative investigation of participants’ experience of chronic administration of a multivitamin. Results uncovered a range of subjective beneficial effects that are consistent with quantitative data from previously published randomised controlled trials examining the effects of multivitamins and B vitamin complexes on mood and well-being.

Leaf Dimorphism Of Microgramma Squamulosa (Polypodiaceae): a qualitative and quantitative analysis focusing on adaptations to epiphytism.  

PubMed

The epiphytic fern Microgramma squamulosa occurs in the Neotropics and shows dimorphic sterile and fertile leaves. The present study aimed to describe and compare qualitatively and quantitatively macroscopic and microscopic structural characteristics of the dimorphic leaves of M. squamulosa, to point more precisely those characteristics which may contribute to epiphytic adaptations. In June 2009, six isolated host trees covered by M squamulosa were selected close to the edge of a semi-deciduous seasonal forest fragment in the municipality of Novo Hamburgo, State of Rio Grande do Sul, Brazil. Macroscopic and microscopic analyzes were performed from 192 samples for each leaf type, and permanent and semi-permanent slides were prepared. Sections were observed under light microscopy using image capture software to produce illustrations and scales, as well as to perform quantitative analyses. Fertile and sterile leaves had no qualitative structural differences, being hypostomatous and presenting uniseriate epidermis, homogeneous chlorenchyma, amphicribal vascular bundle, and hypodermis. The presence of hypodermal tissue and the occurrence of stomata at the abaxial face are typical characteristics ofxeromorphic leaves. Sterile leaves showed significantly larger areas (14.80cm2), higher sclerophylly index (0.13g/cm2) and higher stomatal density (27.75stomata/mm2) than fertile leaves. The higher sclerophylly index and the higher stomatal density observed in sterile leaves are features that make these leaves more xeromorphic, enhancing their efficiency to deal with limited water availability in the epiphytic environment, compared to fertile leaves.

Patient Navigation from the Paired Perspectives of Cancer Patients and Navigators: A Qualitative Analysis  

PubMed Central

Objective Patient navigation for cancer care assesses and alleviates barriers to health care services. We examined paired perspectives of cancer patients and their navigators to examine the process of patient navigation. We explored the strengths, limitations, and our own lessons learned about adopting the novel methodology of multiperspective analysis. Methods As part of a larger RCT, patients and navigators were interviewed separately. We reviewed interviews with 18 patient-navigator dyads. Dyad summaries were created that explicitly incorporated both patient and navigator perspectives. Emerging themes and verbatim quotations were reflected in the summaries. Results Paired perspectives were valuable in identifying struggles that arose during navigation. These were represented as imbalanced investment and relational amelioration. Patients and navigators had general consensus about important patient needs for cancer care, but characterized these needs differently. Conclusion Our experience with multiperspective analysis revealed a methodology that delivers novel relational findings, but is best conducted de novo rather than as part of a larger study. Practice Implications Multiperspective analysis should be more widely adopted with clear aims and analytic strategy that strengthen the ability to reveal relational dynamics. Navigation training programs should anticipate navigator struggles and provide navigators with tools to manage them.

Mortality as an indicator of patient safety in orthopaedics: lessons from qualitative analysis of a database of medical errors  

PubMed Central

Background Orthopaedic surgery is a high-risk specialty in which errors will undoubtedly occur. Patient safety incidents can yield valuable information to generate solutions and prevent future cases of avoidable harm. The aim of this study was to understand the causative factors leading to all unnecessary deaths in orthopaedics and trauma surgery reported to the National Patient Safety Agency (NPSA) over a four-year period (2005–2009), using a qualitative approach. Methods Reports made to the NPSA are categorised and stored in the database as free-text data. A search was undertaken to identify the cases of all-cause mortality in orthopaedic and trauma surgery, and the free-text elements were used for thematic analysis. Descriptive statistics were calculated based on the incidents reported. This included presenting the number of times categories of incidents had the same or similar response. Superordinate and subordinate categories were created. Results A total of 257 incident reports were analysed. Four main thematic categories emerged. These were: (1) stages of the surgical journey – 118/191 (62%) of deaths occurred in the post-operative phase; (2) causes of patient deaths – 32% were related to severe infections; (3) reported quality of medical interventions – 65% of patients experienced minimal or delayed treatment; (4) skills of healthcare professionals – 44% of deaths had a failure in non-technical skills. Conclusions Most complications in orthopaedic surgery can be dealt with adequately, provided they are anticipated and that risk-reduction strategies are instituted. Surgeons take pride in the precision of operative techniques; perhaps it is time to enshrine the multimodal tools available to ensure safer patient care.

A Qualitative Analysis of Factors Influencing HPV Vaccine Uptake in Soweto, South Africa among Adolescents and Their Caregivers  

PubMed Central

Background In South Africa, the prevalence of oncogenic Human Papillomavirus (HPV) may be as high as 64%, and cervical cancer is the leading cause of cancer-related death among women. The development of efficacious prophylactic vaccines has provided an opportunity for primary prevention. Given the importance of psycho-social forces in vaccine uptake, we sought to elucidate factors influencing HPV vaccination among a sample of low-income South African adolescents receiving the vaccine for the first time in Soweto. Methods The HPV vaccine was introduced to adolescents in low-income townships throughout South Africa as part of a nationwide trial to understand adolescent involvement in future vaccine research targeting human immunodeficiency virus (HIV). We performed in-depth semi-structured interviews with purposively-sampled adolescents and their care providers to understand what forces shaped HPV vaccine uptake. Interviews were recorded, transcribed, translated, and examined using thematic analysis. Results Of 224 adolescents recruited, 201 initiated the vaccine; 192 (95.5%) received a second immunization; and 164 (81.6%) completed three doses. In our qualitative study of 39 adolescent-caregiver dyads, we found that factors driving vaccine uptake reflected a socio-cultural backdrop of high HIV endemnicity, sexual violence, poverty, and an abundance of female-headed households. Adolescents exercised a high level of autonomy and often initiated decision-making. Healthcare providers and peers provided support and guidance that was absent at home. The impact of the HIV epidemic on decision-making was substantial, leading participants to mistakenly conflate HPV and HIV. Conclusions In a setting of perceived rampant sexual violence and epidemic levels of HIV, adolescents and caregivers sought to decrease harm by seeking a vaccine targeting a sexually transmitted infection (STI). Despite careful consenting, there was confusion regarding the vaccine’s target. Future interventions promoting STI vaccines will need to provide substantial information for participants, particularly adolescents who may exercise a significant level of autonomy in decision-making.

Qualitative and quantitative analysis of vorticity, strain and area change in general non-isochoric 2D deformation  

NASA Astrophysics Data System (ADS)

A scale free representation of a general non-isochoric 2D deformation is presented which is amenable to mathematical analysis. By describing deformation in 2D in terms of polar coordinates the stretching and rotational histories of linear elements separate and are easily analysed both qualitatively and quantitatively. An analysis of finite strain combined with dynamical considerations allows the derivation of equations which may be used to estimate finite strain, area change and kinematic vorticity number. Numerical investigation of method developed here was carried out and it was found to perform well unless large area changes occur in combination with large components of simple shear. A re-analysis of natural data indicates the method is consistent.

There are a number of forms of creatine available that attempt to improve the solubility and permeability, with the anticipation this will result in an improved pharmacokinetic profile and ultimately an enhanced ergogenic response. Previous research has shown that the different salt forms can improve solubility resulting in slightly altered pharmacokinetic profiles, however specific data exploring the conversion of esterified derivatives to creatine is lacking. The purpose of this study was to examine the assertion that creatine ethyl ester undergoes enzymatic conversion to creatine in human tissues. The IN VITRO response of creatine ethyl ester to incubation in human plasma was examined by H-NMR analysis. Lyophilized human plasma was reconstituted in D2O and phosphate-buffered saline and 1.5 mg of the analyte was added. Following incubation at 37 degrees C for 4 h and subsequent protein precipitation, the supernatant was analyzed by NMR, utilizing the diagnostic chemical shift of the methylene signal to determine the species present in solution, I.E. creatine ethyl ester, creatine, or creatinine. Both creatine and creatinine were run in parallel as control experiments and each assay was run in triplicate. As expected both creatine and creatinine remained unchanged. However, conversion of creatine ethyl ester to creatine by the esterases in human plasma was not observed to any detectable extent and the only species detected after the incubation period was creatinine. While not a definitive characterization of the IN VIVO behavior, these results strongly warrant a complete IN VIVO pharmacokinetic analysis of creatine ethyl ester since it appears these "pronutrients" may actually provide large exogenous sources of pharmacologically inactive creatinine rather than ergogenic creatine.

A Website to Improve Asthma Care by Suggesting Patient Questions for Physicians: Qualitative Analysis of User Experiences  

PubMed Central

Background Asthma is one of the most prevalent chronic conditions in the United Sates, yet despite the existence of national guidelines, nearly three fourths of patients with asthma do not have adequate control and clinical adherence to guidelines is low. While there are many reasons for this, physician inertia with respect to treatment change is partly to blame. Research suggests that patients who ask for specific tests and treatments are more likely to receive them. Objectives This study investigated the impact and experience of using an interactive patient website designed to give patients individual feedback about their condition and to suggest tailored questions for patients to ask their physician. The website was designed to be used prior to a physician visit, to increase the likelihood that patients would receive recommended tests and treatments. Methods A total of 37 adult patients with asthma participated in semi-structured telephone interviews aimed at eliciting information about their experiences with the website. Transcripts were coded using qualitative data analysis techniques and software. Themes were developed from subsets of codes generated through the analysis. In addition, 26 physicians were surveyed regarding their impressions of the website. Results Opportunities exist for improving website feedback, although the majority of both patient and physician respondents held favorable opinions about the site. Two major themes emerged regarding patients’ experiences with the website. First, many patients who used the website had a positive shift in their attitudes regarding interactions with their physicians. Second, use of the website prompted patients to become more actively involved in their asthma care. No patient reported any negative experiences as a result of using the website. Physicians rated the website positively. Conclusions Patients perceived that the interactive website intervention improved communication and interaction with their physicians, suggesting that patients can play a role in overcoming the clinical inertia of providers. Although the design and content of the website can be improved upon, the main findings suggest that use of the website is well accepted and is perceived to improve the quality of care that patients receive.

Qualitative analysis and traveling wave solutions for the perturbed nonlinear Schrödinger's equation with Kerr law nonlinearity  

NASA Astrophysics Data System (ADS)

In this Letter, we investigate the perturbed nonlinear Schrödinger's equation (NLSE) with Kerr law nonlinearity. All explicit expressions of the bounded traveling wave solutions for the equation are obtained by using the bifurcation method and qualitative theory of dynamical systems. These solutions contain bell-shaped solitary wave solutions, kink-shaped solitary wave solutions and Jacobi elliptic function periodic solutions. Moreover, we point out the region which these periodic wave solutions lie in. We present the relation between the bounded traveling wave solution and the energy level h. We find that these periodic wave solutions tend to the corresponding solitary wave solutions as h increases or decreases. Finally, for some special selections of the energy level h, it is shown that the exact periodic solutions evolute into solitary wave solution.

The Relationship between Housing Status and HIV Risk among Active Drug Users: A Qualitative Analysis  

PubMed Central

This paper examines the relationship between housing status and HIV risk using longitudinal, qualitative data collected in 2004-2005, from a purposeful sample of 65 active drug users in a variety of housed and homeless situations in Hartford, Connecticut. These data were supplemented with observations and in-depth interviews regarding drug use behavior collected in 2001-2005 to evaluate a peer-led HIV prevention intervention. Data reveal differences in social context within and among different housing statuses that affect HIV risky or protective behaviors including the ability to carry drug paraphernalia and HIV prevention materials, the amount of drugs in the immediate environment, access to subsidized and supportive housing, and relationships with others with whom drug users live. Policy implications of the findings, limitations to the data and future research are discussed.

Usability of geographic information - Factors identified from qualitative analysis of task-focused user interviews.  

PubMed

Understanding user needs for geographic information and the factors which influence the usability of such information in diverse user contexts is an essential part of user centred development of information products. There is relatively little existing research focused on the design and usability of information products in general. This paper presents a research approach based on semi structured interviews with people working with geographic information on a day to day basis, to establish a reference base of qualitative data on user needs for geographic information with respect to context of use. From this reference data nine key categories of geographic information usability are identified and discussed in the context of limited existing research concerned with geographic information usability.

Conversations between carers and people with schizophrenia: a qualitative analysis using leximancer.  

PubMed

We examined conversations between people with schizophrenia (PwS) and family or professional carers with whom they interacted frequently. We allocated PwS to one of two communication profiles: Low-activity communicators talked much less than their conversational partners, whereas high-activity communicators talked much more. We used Leximancer text analytics software to analyze the conversations. We found that carers used different strategies to accommodate to the PwS's behavior, depending on the PwS's communication profile and their relationship. These findings indicate that optimal communication strategies depend on the PwS's conversational tendencies and the relationship context. They also suggest new opportunities for qualitative assessment via intelligent text analytics technologies. PMID:20675536

High hepatitis C seroprevalence in Thai intravenous drug abusers and qualitative risk analysis.  

PubMed

One of the high risk groups of hepatitis C virus infection is intravenous drug abusers (IVDAs). The study of HCV seroprevalence and some qualitative risk factors in this target group can be valuable for prevention of the infection. During June to October 1992, a cross-sectional study of 150 intravenous male drug abusers seeking medical treatment at Phranangkhlao and Rajavithi Hospitals was conducted. Blood specimens were collected for determining anti-HCV antibody by EIA. An in-depth interview was carried out searching for some qualitative risk factors in anti-HCV positive and negative IVDAs. It was found that 95.33% of studied IVDAs were positive for anti-HCV antibody. There was no significant difference between the prevalence of anti-HCV and their ages (p > 0.05). The antibody prevalence trended to be higher with the longer duration of drug use. The positive rate of IVDAs who had injected more than 8 years was significantly higher than that of IVDAs who had injected less than 2 years (100% and 85.71), p = 0.004. Alanine amino-transferase (ALT) levels and anti-HIV antibodies were determined. IVDAs with higher levels of anti-HCV had higher percentages of ALT abnormality and anti-HIV positive rates. Data from in-depth interview showed that the longer duration of imprisonment, tattoo/ear piercing, extramarital relations without using condoms, the longer duration of drug use and needle/syringe sharing were potential risk factors for HCV infection in this target group.

Perceived challenges to public health in Central and Eastern Europe: a qualitative analysis  

PubMed Central

Background There is a major gradient in burden of disease between Central and Eastern Europe compared to Western Europe. Many of the underlying causes and risk factors are amenable to public health interventions. The purpose of the study was to explore perceptions of public health experts from Central and Eastern European countries on public health challenges in their countries. Methods We invited 179 public health experts from Central and Eastern European countries to a 2-day workshop in Berlin, Germany. A total of 25 public health experts from 14 countries participated in May 2008. The workshop was structured into 8 sessions of 1.5 hours each, with the topic areas covering coronary heart disease, stroke, prevention, obesity, alcohol, tobacco, tuberculosis, and HIV/AIDS. The workshop was recorded and the proceedings transcribed verbatim. The transcripts were entered into atlas.ti for content analysis and coded according to the session headings. After analysis of the content of each session discussion, a re-coding of the discussions took place based on the themes that emerged from the analysis. Results Themes discussed recurred across disease entities and sessions. Major themes were the relationship between clinical medicine and public health, the need for public health funding, and the problems of proving the effectiveness of disease prevention. Areas for action identified included the need to engage with the public, to create a better scientific basis for public health interventions, to identify “best practices” of disease prevention, and to implement registries/surveillance instruments. The need for improved data collection was seen throughout all areas discussed, as was the need to harmonize data across countries. Conclusions To reduce the burden of disease across Europe, closer collaboration of countries across Europe seems important in order to learn from each other. A more credible scientific basis for effective public health interventions is urgently needed. The monitoring of health trends is crucial to evaluate the impact of public health programmes.

Perceptions and Experiences of Women in Karachi, Pakistan Regarding Secondary Infertility: Results from a Community-Based Qualitative Study  

PubMed Central

Background. The prevalence of infertility in Pakistan is 22% with primary infertility at 4% and secondary infertility at 18%. This study explored perceptions and experiences of women in Karachi, Pakistan regarding the causes, treatment-seeking behavior for and consequences of secondary infertility. Methods. Focus group discussions and in-depth interviews with married women explored their perceptions and experiences for issues related to secondary infertility. Results. The knowledge of women about the causes and scientific treatment options for infertility was limited resulting in inclination for traditional unsafe health care. Infertility was stated to result in marital instability, stigmatization and abuse specially for women with no live child. Conclusions. Since infertility can have a serious effect on both the psychological well-being and the social status of women in Pakistan, effective interventions are the need of the day. There is a dire need for health education and counseling to be integrated into infertility management plans.

Qualitative and Quantitative Analysis of Andrographis paniculata by Rapid Resolution Liquid Chromatography/Time-of-Flight Mass Spectrometry.  

PubMed

A rapid resolution liquid chromatography/time-of-flight tandem mass spectrometry (RRLC-TOF/MS) method was developed for qualitative and quantitative analysis of the major chemical constituents in Andrographis paniculata. Fifteen compounds, including flavonoids and diterpenoid lactones, were unambiguously or tentatively identified in 10 min by comparing their retention times and accurate masses with standards or literature data. The characteristic fragmentation patterns of flavonoids and diterpenoid lactones were summarized, and the structures of the unknown compounds were predicted. Andrographolide, dehydroandrographolide and neoandrographolide were further quantified as marker substances. It was found that the calibration curves for all analytes showed good linearity (R2 > 0.9995) within the test ranges. The overall limits of detection (LODs) and limits of quantification (LOQs) were 0.02 ?g/mL to 0.06 ?g/mL and 0.06 ?g/mL to 0.2 ?g/mL, respectively. The relative standard deviations (RSDs) for intra- and inter-day precisions were below 3.3% and 4.2%, respectively. The mean recovery rates ranged from 96.7% to 104.5% with the relative standard deviations (RSDs) less than 2.72%. It is concluded that RRLC-TOF/MS is powerful and practical in qualitative and quantitative analysis of complex plant samples due to time savings, sensitivity, precision, accuracy and lowering solvent consumption.

Precursors and Trajectories of Sensory Features: Qualitative Analysis of Infant Home Videos  

PubMed Central

Objectives This study explored precursors and trajectories of extreme sensory patterns in children with ASD compared to DD. Methods A retrospective analysis of infant home videos was conducted with 12 cases that displayed extreme presence or absence of three sensory patterns at preschool and school age. Results In ASD, hyporesponsiveness was most evident in infancy, followed by sensory repetitions. Hypo-responsiveness appeared stable over time and also as a precursor of sensory seeking. Infants with DD had few sensory precursors. Conclusions Precursors of extreme sensory features emerge early in children with ASD, and appear relatively stable over time for a pattern of hyporesponsiveness, but less so for patterns of hyperresponsiveness and sensory seeking. These findings highlight the emergent nature of sensory features that may inform early identification and intervention.

A qualitative analysis of the meaning of aging for women with disabilities with policy implications.  

PubMed

This is a report of a hermeneutic phenomenological study of the meaning of aging for women with childhood-onset disabilities due to the effects of paralytic polio. Twenty-five women aged 55-65 years were interviewed 2 to 4 times regarding their life course experiences and the meaning they assigned to aging. Field notes, audiotaped interviews, life course charts, and demographics were used in thethematic analysis that produced 5 themes: Bodies Change, Disrupted Meaning, The Unpredictibility of Aging, Slowing Down, and Changing Perspective. Overall, the findings indicate that the experiences of disability due to the result of paralytic polio could not be separated from the experiences of aging, which ultimately led the author to question policies that distribute and fund benefits based on age and disability status without an understanding of the varied experiences of women with disabilities.

Comparison of face-to-face and telephone consultations in primary care: qualitative analysis  

PubMed Central

Background There is evidence that telephone consultations in general practice are typically shorter than face-to-face consultations and that fewer problems are presented in them. Aim To compare the communicative practices of doctors and patients in face-to-face and telephone consultations, in order to understand the contrasts between the two consulting modes. Design of study Conversation analysis. Setting Eight NHS GP surgeries in Scotland. Method Transcription and conversation analysis of 32 face-to-face and 33 telephone consultations. Participants Eighteen GPs and 65 patients. Results There are no underlying contrasts between the communicative practices used in face-to-face and telephone consultations. Telephone consultations are typically used by patients to deal with a limited range of single-issue concerns, whereas a wide range of different problem types is dealt with in face-to-face consultations. Most telephone consultations for new problems lead to a face-to-face meeting rather than a diagnosis, making them shorter than equivalent face-to-face consultations. Interaction in telephone consultations is continuous and orderly, but in face-to-face consultations there are periods of silence that facilitate the introduction of additional topics, including social speech and rapport building. Doctors on the telephone are less likely to elicit additional concerns than in face-to-face consultations, and ask fewer questions when patients present self-diagnosed problems or describe problems with treatment. Conclusion Doctors in general practice do not substantially change their communicative behaviour on the telephone. Telephone consultations are shorter and include less problem disclosure than face-to-face meetings, partly because they are typically mono-topical and partly because of intrinsic differences between the two channels.

Qualitative analysis of sequence specific binding of flavones to DNA using restriction endonuclease activity assays.  

PubMed

Flavones, found in nature as secondary plant metabolites, have shown efficacy as anti-cancer agents. We have examined the binding of two flavones, 5,7-dihydroxy-3,6,8-trimethoxy-2-phenyl-4H-chromen-4-one (5,7-dihydroxy-3,6,8-trimethoxy flavone; FlavA) and 3,5-dihydroxy-6,7,8-trimethoxy-2-phenyl-4H-chromen-4-one (3,5-dihydroxy-6,7,8-trimethoxy flavone; FlavB), to phiX174 RF DNA using restriction enzyme activity assays employing the restriction enzymes Alw44, AvaII, BssHII, DraI, MluI, NarI, NciI, NruI, PstI, and XhoI. These enzymes possess differing target and flanking sequences allowing for observation of sequence specificity analysis. Using restriction enzymes that cleave once with a mixture of supercoiled and relaxed DNA substrates provides for observation of topological effects on binding. FlavA and FlavB show differing sequence specificities in their respective binding to phiX. For example, with relaxed DNA, FlavA shows inhibition of cleavage with DraI (reaction site (5') TTTAAA) but not BssHII ((5') GCGCGC) while FlavB shows the opposite results. Evidence for tolological specificity is also observed, Molecular modeling and conformational analysis of the flavones suggests that the phenyl ring of FlavB is coplanar with the flavonoid ring while the phenyl ring of FlavA is at an angle relative to the flavonoid ring. This may account for aspects of the observed sequence and topological specificities in the effects on restriction enzyme activity. © 2013 Wiley Periodicals, Inc. Biopolymers 99: 530-537, 2013.

Equity in public health standards: a qualitative document analysis of policies from two Canadian provinces  

PubMed Central

Introduction Promoting health equity is a key goal of many public health systems. However, little is known about how equity is conceptualized in such systems, particularly as standards of public health practice are established. As part of a larger study examining the renewal of public health in two Canadian provinces, Ontario and British Columbia (BC), we undertook an analysis of relevant public health documents related to equity. The aim of this paper is to discuss how equity is considered within documents that outline standards for public health. Methods A research team consisting of policymakers and academics identified key documents related to the public health renewal process in each province. The documents were analyzed using constant comparative analysis to identify key themes related to the conceptualization and integration of health equity as part of public health renewal in Ontario and BC. Documents were coded inductively with higher levels of abstraction achieved through multiple readings. Sets of questions were developed to guide the analysis throughout the process. Results In both sets of provincial documents health inequities were defined in a similar fashion, as the consequence of unfair or unjust structural conditions. Reducing health inequities was an explicit goal of the public health renewal process. In Ontario, addressing “priority populations” was used as a proxy term for health equity and the focus was on existing programs. In BC, the incorporation of an equity lens enhanced the identification of health inequities, with a particular emphasis on the social determinants of health. In both, priority was given to reducing barriers to public health services and to forming partnerships with other sectors to reduce health inequities. Limits to the accountability of public health to reduce health inequities were identified in both provinces. Conclusion This study contributes to understanding how health equity is conceptualized and incorporated into standards for local public health. As reflected in their policies, both provinces have embraced the importance of reducing health inequities. Both concepualized this process as rooted in structural injustices and the social determinants of health. Differences in the conceptualization of health equity likely reflect contextual influences on the public health renewal processes in each jurisdiction.

Online Pediatric Information Seeking Among Mothers of Young Children: Results From a Qualitative Study Using Focus Groups  

PubMed Central

Background Pre-natal and post-natal periods are times when many women actively seek health information from multiple sources, including the Internet. However, little is known about how pregnant women and mothers of young children seek and process online pediatric health information. Objective To explore why and where mothers of young children look for online health information and how they determine if the information they receive is trustworthy. Methods Focus groups were conducted in a Southeastern US city to provide an in-depth exploration of web-related behaviors and beliefs among mothers who work inside and outside of the home. Data from the focus groups were coded using deductive and inductive coding schemes and content was analyzed for the existence of themes. Results Twenty mothers of young children participated in four focus groups. Most participants sought information on the Internet during pregnancy and nearly all sought online information after their child was born, primarily to diagnose or treat pediatric conditions and to seek advice on parenting and development. Participants mainly used commercial information websites for health information and many expressed disdain for commercial product websites. Many also expressed concerns about the reliability of health information on the web and described strategies for determining how much they trust each website. Conclusions Women appear to be high information seekers during pregnancy and the first few years following delivery, and this period represents an important window of time for providing online health information. Participants suggested that online information sources and motives for providing online information should be clear in order to increase perceptions of trust. Participants expressed preference for online clinical health information that is presented by clinical professionals, and online parenting advice that is presented from other parents.

Organizational and Physician Perspectives about Facilitating Handheld Computer Use in Clinical Practice: Results of a Cross-Site Qualitative Study  

PubMed Central

Objective: To describe strategies that organizations select to support physicians' use of handheld computers (HHCs) in clinical practice and to explore issues about facilitating HHC use. Design: A multidisciplinary team used focus groups and interviews with clinical, administrative, and information technology (IT) staff to gather data from 161 informants at seven sites. Transcripts were coded using a combination of deductive and inductive approaches to both answer research questions and identify patterns and themes that emerged in the data. Measurements: Answers to questions about strategies for HHC support and themes about (1) how to facilitate physician adoption and use and (2) organizational concerns. Results: Three main organizational strategies for HHC support were characterized among sites: (1) active support for broad-based use, (2) active support for niche use, and (3) basic support for individual physician users. Three high-level themes emerged around how to best facilitate physician adoption and use of HHCs: (1) improving usability and usefulness, (2) promoting HHCs and device use, and (3) providing training and support. However, four major themes also emerged related to organizations' concerns about HHC use: (1) security-related concerns, (2) economic concerns, (3) technical concerns, and (4) strategic concerns. Conclusion: An organizational approach to HHC support that involves individualized attention to existing and potential physician users rather than one-size-fits-all, organization-wide implementation efforts was an important facilitator promoting physician use of HHCs. Health care organizations interested in supporting HHC use must consider issues related to security, economics, and IT strategy that may not be prominent concerns for physician users.

Negotiating uncertain terrain: a qualitative analysis of clinicians' experiences of refractory suffering.  

PubMed

In palliative care, the witnessing of unrelieved (refractory) suffering takes its toll on all concerned; however, the effect on experienced palliative clinicians of witnessing such suffering has largely been unexplored. The aim of this study was to examine health care professionals' (nurses, doctors, and allied health workers) experiences of working with a patient's refractory suffering, together with their clinical management strategies. A qualitative research design involving semistructured interviews and an online questionnaire was used to collect the data. Seventeen experienced palliative care clinicians participated; 13 with face-to-face interviews and a further 4 by an online questionnaire. The overarching theme of negotiating uncertain terrain was common across all clinician narratives. In order for them to work successfully with a patient's refractory suffering, the clinicians had to negotiate areas of practice characterized by uncertainty, with no clear directions and with few expert guides. In reviewing their experiences, they identified within an overarching theme of negotiating uncertain terrain four subthemes: Changing Approach from "Fixing" to "Being With," Maintaining Perspective, Negotiating and Maintaining Boundaries, and Living the Paradoxes. This study highlights that dealing with patients' refractory suffering involves clinicians moving into uncertain and unexplored territory. For them to work effectively in this terrain the clinicians need wisdom, courage, and a commitment to journeying alongside the suffering person. PMID:22621305

The Incredible Years parenting program in Ireland: a qualitative analysis of the experience of disadvantaged parents.  

PubMed

Controlled trials demonstrate that parenting programs work, but less is known about the processes of change, contextual factors or intervention characteristics that influence trial outcomes. This qualitative study assessed the experiences of Irish parents involved in a randomized controlled trial of the Incredible Years BASIC parenting program, with a view to understanding how and why the program works, or does not work, within disadvantaged settings. Data from 33 parents of young children (aged 3-7 years) with conduct problems were collected by semi-structured interviews and analysed using constructivist grounded theory. Emerging themes indicated that parents perceived the program to have produced positive changes through learning key parenting skills (e.g. positive attention, empathy and problem-solving skills) and through enhanced parental mood/confidence, derived primarily from gaining non-judgmental support from the group. Parents also experienced cultural, personal and environmental challenges in learning the new skills, including discomfort with praise and positive attention, conflict with their partner and parenting within an antisocial environment. Parents dropped out of the course for largely circumstantial reasons. These findings should help to inform the future implementation of this well-known parenting program both in Ireland and elsewhere. PMID:22104366

A qualitative approach to signal mining in pharmacovigilance using formal concept analysis.  

PubMed

"Pharmacovigilance is the process and science of monitoring the safety of medicines, consisting in (i) collecting and managing data on the safety of medicines (ii) looking at the data to detect 'signals' (any new or changing safety issue)" [1]. Pharmacovigilance is mainly based on spontaneous reports: when suspecting an adverse drug reaction, health care practitioners send a report to a spontaneous reporting system (SRS). This produces huge databases containing numerous reports and their manual exploration is both cost and time prohibitive. Existing techniques that automatically extract relevant signals rely on statistics or Bayesian models but do not provide information to the experts about possible biases lying in the data, nor about the specificity of a signal to a particular patient profile. Our extraction method combines numerical methods from the state of the art with a qualitative approach that helps interpretation. We build a synthetic representation of the database that is used to (i) identify unexpected patterns and biases (ii) extract potentially relevant signals w.r.t. patient profiles (iii) provide traceability facilities between extracted signals and raw data.

Parent-Child Collaborative Decision Making for the Management of Chronic Illness: A Qualitative Analysis  

PubMed Central

Parent-child collaborative decision making (CDM) is a potentially important precursor to full decision making independence and may be particularly significant for the management of childhood chronic illnesses. The primary aim of this qualitative study was to explore the concept of CDM from the perspective of children and parents. Children (ages 8-19 years) with asthma, type 1 diabetes, or cystic fibrosis and parents of children with these illnesses participated in focus groups and individual interviews. Participants described various ways they collaborate with one another (e.g., asking for the other's opinion; providing information). Participants viewed collaboration as beneficial, regardless of who ultimately makes the decision. Several factors emerged as potential predictors of CDM, including parent/family factors (e.g., parental time; parent-child conflict), child factors (e.g., maturity; emotional/behavioral functioning), and decision/situation factors (e.g., seriousness of the decision; extent to which the child is experiencing symptoms). These data suggest ways to enhance collaborative decision making interactions between children with a chronic illness and their parents, as well as several areas for future quantitative research.

A qualitative and quantitative analysis of the characteristics of gout patient education resources.  

PubMed

Patient education is an important aspect of gout management, but there is evidence that many patients lack adequate knowledge of their condition. Our aim was to examine the characteristics of gout patient education resources. Ten gout patient information resources were examined for readability (Flesch-Kincaid reading level, the Simple Measure of Gobbledygook measure and the Flesch Reading Ease Score), qualitative characteristics such as figure and jargon use and whether they included information on the major points of gout. The median readability grade level of the examined resources was 8.5. The difference in readability grade level between the highest and the lowest education resource was 6.3 grade levels. The information content of the resources was high with an average of only 3.9 proposed criteria of 19 (19 %) absent from the resources. Jargon use was low and concepts were usually explained. However, important information regarding acute flare prophylaxis during urate-lowering therapy initiation and titration and treating serum uric acid to target was absent from 60 % of the patient education resources. There was poor use of key messages at the start. Gout patient resources have a wide range of readability. Thirty percent of resources were above the average reading level of rheumatology outpatients reported in previous studies. Sixty percent of gout patient resources omit education items that could impact on patient adherence and in turn patient outcomes. Further research is needed into the literacy levels and education requirements of patients with gout. PMID:23322247

HIV testing and disclosure: a qualitative analysis of TB patients in South Africa.  

PubMed

In South Africa, more than 60% of TB patients have HIV co-infection. Voluntary counseling and testing (VCT) is critical to effective HIV prevention, and TB facilities are optimal venues for delivery of these services. This study employed qualitative research methods to explore the decision-making processes for HIV testing and serostatus disclosure by 21 patients hospitalized with multi/extensively-drug resistant TB (M/XDR-TB) in Durban, KwaZulu Natal. Data collected from in-depth interviews characterized 3 broad themes: HIV testing history, experiences and perceptions of stigma and disclosure, and the relationship between TB and HIV/AIDS. Fear of AIDS-related stigma, the singular stress of TB infection, the absence of partner's consent, asymptomatic or incurable disease, and uncertainty about subsequent eligibility for antiretroviral treatment while still receiving TB treatment were identified as potential barriers to the uptake of VCT. HIV serostatus disclosure was impeded by the felt stigma of a 'discreditable' infection, manifested by social rejection and discrimination. The public disclosure of TB illness helped relieve some co-infected patients' overall burden of stigma through a process of 'covering'. HIV prevention [corrected] measures such as VCTare likely to be more effective within TB facilities if greater sensitivity is paid to TB patients' specific social issues and perceptions. These patients are not only at greater risk for HIV co-infection but also for experiencing the double stigma of TB and HIV/AIDS. PMID:17453600

Danish and Finnish PISA Results in a Comparative, Qualitative Perspective: How Can the Stable and Distinct Differences between the Danish and Finnish PISA Results Be Explained?  

ERIC Educational Resources Information Center

|The research project presented in this article was designed to provide a better understanding of the stable and significant differences in the PISA results between two otherwise very similar Nordic welfare states, Denmark and Finland.

Cultural beliefs that may discourage breastfeeding among Lebanese women: a qualitative analysis  

PubMed Central

Background Although the health benefits of breastfeeding are well established, early introduction of formula remains a common practice. Cultural beliefs and practices can have an important impact on breastfeeding. This paper describes some common beliefs that may discourage breastfeeding in Lebanon. Methods Participants were healthy first-time mothers recruited from hospitals throughout Lebanon to participate in a study on usage patterns of a telephone hotline for postpartum support. The hotline was available to mothers for the first four months postpartum and patterns of usage, as well as questions asked were recorded. Thematic analysis of the content of questions which referred to cultural beliefs and practices related to breastfeeding was conducted. Results Twenty four percent of the 353 women enrolled in the study called the hotline, and 50% of the calls included questions about breastfeeding. Mothers expressed concern about having adequate amounts of breast milk or the quality of their breast milk. Concerns that the mother could potentially harm her infant though breastfeeding were rooted in a number of cultural beliefs. Having an inherited inability to produce milk, having "bad milk", and transmission of abdominal cramps to infants through breast milk were among the beliefs that were expressed. Although the researchers live and work in Lebanon, they were not aware of many of the beliefs that are reported in this study. Conclusion There are a number of cultural beliefs that could potentially discourage breastfeeding among Lebanese women. Understanding and addressing local beliefs and customs can help clinicians to provide more culturally appropriate counselling about breastfeeding.

Politics and its intersection with coverage with evidence development: a qualitative analysis from expert interviews  

PubMed Central

Background Pressures on health care budgets have led policy makers to discuss how to balance the provision of costly technologies to populations in need and making coverage decisions under uncertainty. Coverage with evidence development (CED) is being employed to meet these challenges. Methods Twenty-four interviews were carried out between June 2009 and December 2010 with researchers, decision makers and policy makers from Australia, Canada, United Kingdom and United States. Three phases of coding occurred, the first being manual coding where the interviews were read and notes were taken and nodes were extracted and imputed. NVIVO coding was applied to the interview transcripts, with both broad general searches for word usages and imputed nodes. Results Four overarching thematic areas emerged out of contextual analysis of the interviews – (1) what constitutes CED; (2) the lack of a systematic approach/governance structure; (3) the role of the pharmaceutical industry and overt political considerations in CED; and (4) alternatives and barriers to CED. We explore these themes and then use concrete examples of CED projects in each of the four countries to illustrate the political issues that our interviewees raised. Conclusion Until the underlying political nature of CED is recognized then fundamental questions about its usefulness and operation will remain unresolved.
