A study has been completed to define a Shuttle experiment that solves the most crucial scientific and engineering problems involved in building a satellite Doppler wind profiler for making global wind measurements. The study includes: (1) a laser study to determine the feasibility of using the existing NOAA Windvan laser in the Space Shuttle spacecraft; (2) a preliminary optics and telescope design; (3) an accommodations study including power, weight, thermal, and control system requirements; and (4) a flight trajectory and operations plan designed to accomplish the required scientific and engineering goals. The experiment will provide much-needed data on the global distribution of atmospheric aerosols and demonstrate the technique of making wind measurements from space, including scanning the laser beam and interpreting the data. Engineering accomplishments will include space qualification of the laser, development of signal processing and lag angle compensation hardware and software, and telescope and optics design. All of the results of this limited Spacelab experiment will be directly applicable to a complete satellite wind profiler for the Earth Observation System/Space Station or other free-flying satellite.

For cancer patients, uncertainty is a pervasive experience and a major psychological stressor that affects many aspects of their lives. Uncertainty is a multifaceted concept, and its understanding for patients depends on many factors, including factors associated with various sociocultural contexts. Unfortunately, little is known about the concept of uncertainty in Iranian society and culture. This study aimed to clarify the concept and explain lived experiences of illness uncertainty in Iranian cancer patients. In this hermeneutic phenomenological study, 8 cancer patients participated in semistructured in-depth interviews about their experiences of uncertainty in illness. Interviews continued until data saturation was reached. All interviews were recorded, transcribed, analyzed, and interpreted using 6 stages of the van Manen phenomenological approach. Seven main themes emerged from patients' experiences of illness uncertainty of cancer. Four themes contributed to uncertainty including "Complexity of Cancer," "Confusion About Cancer," "Contradictory Information," and "Unknown Future." Two themes facilitated coping with uncertainty including "Seeking Knowledge" and "Need for Spiritual Peace." One theme, "Knowledge Ambivalence," revealed the struggle between wanting to know and not wanting to know, especially if bad news was delivered. Uncertainty experience for cancer patients in different societies is largely similar. However, some experiences (eg, ambiguity in access to medical resources) seemed unique to Iranian patients. This study provided an outlook of cancer patients' experiences of illness uncertainty in Iran. Cancer patients' coping ability to deal with uncertainty can be improved.

Longitudinal effects of disaster-related experiences on mental health among Fukushima nuclear plant workers: The Fukushima NEWS Project Study.

The Fukushima Nuclear Energy Workers' Support (NEWS) Project Study previously showed that experiences related to the Fukushima nuclear disaster on 11 March 2011 had a great impact on psychological states, including post-traumatic stress response (PTSR) and general psychological distress (GPD), among the Fukushima nuclear plant workers. To determine the causal relationship between disaster-related experiences and levels of psychological states, we conducted a 3-year longitudinal study from 2011 to 2014. PTSR and GPD of the nuclear plant workers were assessed by annual questionnaires conducted from 2011 to 2014. The present study included a total of 1417 workers who provided an assessment at baseline (2011). A total of 4160 observations were used in the present analysis. The relationship between disaster-related experiences and psychological states over time was analysed using mixed-effects logistic regression models. A declining influence of disaster-related experiences on PTSR over time was found. However, the impact on PTSR remained significantly elevated even 3 years after the disaster in several categories of exposure including the experience of life-threatening danger, experiences of discrimination, the witnessing of plant explosion, the death of a colleague and home evacuation. The associations between GPD and disaster-related experiences showed similar effects. The effects of disaster-related experiences on psychological states among the nuclear plant workers reduced over time, but remained significantly high even 3 years after the event.

Study abroad programs have increased dramatically. Most programs are short-term and include a cultural immersion as well as classroom and/or service learning. In this article, the authors discuss a study abroad program to China that included cultural immersion and classroom learning specific to traditional Chinese medicine. Participants kept journals with specific writing assignments and reflections about their experiences during the trip. At the conclusion of the trip, a qualitative survey was administered to the participants. Outcomes included the benefits of cultural immersion and a greater appreciation of cultural diversity, complementary and alternative medicine and holistic health care. Participants were able to describe transformational experiences of living in and learning from the Chinese culture and peoples. They intended to incorporate their experiences and enhanced understanding of traditional Chinese medicine and complementary and alternative therapies to provide culturally competent holistic health care in their nursing practice. © The Author(s) 2015.

A preliminary study of a cryogenic equivalence principle experiment on Shuttle

NASA Technical Reports Server (NTRS)

Everitt, C. W. F.; Worden, P. W., Jr.

1985-01-01

The Weak Equivalence Principle is the hypothesis that all test bodies fall with the same acceleration in the same gravitational field. The current limit on violations of the Weak Equivalence Principle, measured by the ratio of the difference in acceleration of two test masses to their average acceleration, is about 3 parts in one-hundred billion. It is anticipated that this can be improved in a shuttle experiment to a part in one quadrillion. Topics covered include: (1) studies of the shuttle environment, including interference with the experiment, interfacing to the experiment, and possible alternatives; (2) numerical simulations of the proposed experiment, including analytic solutions for special cases of the mass motion and preliminary estimates of sensitivity and time required; (3) error analysis of several noise sources such as thermal distortion, gas and radiation pressure effects, and mechanical distortion; and (4) development and performance tests of a laboratory version of the instrument.

Influencing attitudes toward science through field experiences in biology

NASA Astrophysics Data System (ADS)

Carpenter, Deborah Mcintyre

The purpose of this study was to determine how student attitudes toward science are influenced by field experiences in undergraduate biology courses. The study was conducted using two institutions of higher education including a 2-year lower-level and a 2-year upper-level institution. Data were collected through interviews with student participants, focus group discussions, students' journal entries, and field notes recorded by the researcher during the field activities. Photographs and video recordings were also used as documentation sources. Data were collected over a period of 34 weeks. Themes that emerged from the qualitative data included students' beliefs that field experiences (a) positively influence student motivation to learn, (b) increase student ability to learn the concepts being taught, and (c) provide opportunities for building relationships and for personal growth. The findings of the study reinforce the importance of offering field-study programs at the undergraduate level to allow undergraduate students the opportunity to experience science activities in a field setting. The research study was framed by the behavioral and developmental theories of attitude and experience including the Theory of Planned Behavior (Ajzen, 1991) and the Theory of Experiential Learning (Kolb, 1984).

Microorganisms can be used as model systems for studying biological responses to extraterrestrial conditions; however, the methods for studying their response are extremely challenging. Since the first high altitude microbiological experiment in 1935 a large number of facilities have been developed for short- and long-term microbial exposure experiments. Examples are the BIOPAN facility, used for short-term exposure, and the EXPOSE facility aboard the International Space Station, used for long-term exposure. Furthermore, simulation facilities have been developed to conduct microbiological experiments in the laboratory environment. A large number of microorganisms have been used for exposure experiments; these include pure cultures and microbial communities. Analyses of these experiments have involved both culture-dependent and independent methods. This review highlights and discusses the facilities available for microbiology experiments, both in space and in simulation environments. A description of the microorganisms and the techniques used to analyse survival is included. Finally we discuss the implications of microbiological studies for future missions and for space applications. Copyright 2009 Elsevier B.V. All rights reserved.

Assessing healthcare professionals' experiences of integrated care: do surveys tell the full story?

PubMed

Stephenson, Matthew D; Campbell, Jared M; Lisy, Karolina; Aromataris, Edoardo C

2017-09-01

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

The experiences of midwives and nurses collaborating to provide birthing care: a systematic review.

Collaboration has been associated with improved health outcomes in maternity care. Collaborative relationships between midwives and physicians have been a focus of literature regarding collaboration in maternity care. However despite the front line role of nurses in the provision of maternity care, there has not yet been a systematic review conducted about the experiences of midwives and nurses collaborating to provide birthing care. The objective of this review was to identify, appraise and synthesize qualitative evidence on the experiences of midwives and nurses collaborating to provide birthing care.Specifically, the review question was: what are the experiences of midwives and nurses collaborating to provide birthing care? This review considered studies that included educated and licensed midwives and nurses with any length of practice. Nurses who work in labor and delivery, postpartum care, prenatal care, public health and community health were included in this systematic review.This review considered studies that investigated the experiences of midwives and nurses collaborating during the provision of birthing care. Experiences, of any duration, included any interactions between midwives and nurses working in collaboration to provide birthing care.Birthing care referred to: (a) supportive care throughout the pregnancy, labor, delivery and postpartum, (b) administrative tasks throughout the pregnancy, labor, delivery and postpartum, and (c) clinical skills throughout the pregnancy, labor, delivery and postpartum. The postpartum period included the six weeks after delivery.The review considered English language studies that focused on qualitative data including, but not limited to, designs such as phenomenology, grounded theory, ethnography, action research and feminist research.This review considered qualitative studies that explored the experiences of collaboration in areas where midwives and nurses work together. Examples of these areas included: hospitals, birth centers, client homes, health clinics and other public or community health settings. These settings were located in any country, cultural context, or geographical location. A three-step search strategy was used to identify relevant published and unpublished studies. English papers from 1981 onwards were considered. The following databases were searched: Anthrosource, CENTRAL (The Cochrane Library), CINAHL, EMBASE, PsycINFO, PubMed, Social Services Abstracts and Sociological Abstracts. In addition to the databases, several grey literature sources were searched. Papers that were selected for retrieval were independently assessed for inclusion in the review by two JBI-trained reviewers. The two reviewers used a standardized critical appraisal instrument from the Joanna Briggs Institute Qualitative Assessment and Review Instrument. Qualitative data were extracted from papers included in the review using the standardized data extraction tool from the Joanna Briggs Institute Qualitative Assessment and Review Instrument. Once qualitative studies were assessed using the the Joanna Briggs Institute Qualitative Assessment and Review Instrument critical appraisal tool, findings of the included studies were extracted. These findings were aggregated into categories according to their similarity in meaning. These categories were then subjected to a meta-synthesis to produce a comprehensive set of synthesized findings. Five studies were included in the review. Thirty-eight findings were extracted from the included studies and were aggregated into five categories. The five categories were synthesized into two synthesized findings. The two synthesized findings were:Synthesized finding1: Negative experiences of collaboration between nurses and midwives may be influenced by distrust, lack of clear roles, or unprofessional or inconsiderate behavior.Synthesized finding 2: If midwives and nurses have positive experiences collaborating thenthere is hope that the challenges of collaboration can be overcome. Qualitative evidence about the experiences of midwives and nurses collaborating to provide birthing care was identified, appraised and synthesized. Two synthesized findings were created from the findings of the five included studies. Midwives and nurses had negative experiences of collaboration which may be influenced by: distrust, unclear roles, or a lack of professionalism or consideration. Midwives and nurses had positive experiences of teamwork which can be a source of hope for overcoming the challenges of sharing care.There is clearly a gap in the literature about the collaborative experiences of midwives and nurses, given that only five studies were located for inclusion in the systematic review. More qualitative research exploring collaboration as a process and the interactional dynamics of midwives and nurses in a variety of practice and professional contexts is required.Distrust, unclear roles, and lack of professionalism and consideration must all be addressed. Strategies that address and minimize the occurrences of these three elements need to be developed and implemented in an effort to reduce negative collaborative experiences for midwives and nurses. Postive experiences of teamwork must be acknowleged and celebrated, and the challenges that sharing care present must be understood as a part of the collaborative process.More qualitative research is required to explore the collaborative process between midwives and nurses. Further exploration of their interactional dynamics, their relationship between power and collaboration, and the experiences of collaboration in a variety of professional and practice contexts is recommended.

Pain is a universal and complex phenomenon that is personal, subjective and specific. Despite growing knowledge in pediatric pain, management of children's pain remains sub-optimal and is linked to negative behavioral and physiological consequences later in life. As there is no synthesis of these studies, it was timely to undertake a systematic review. To identify, evaluate and synthesize the existing qualitative evidence on children's experiences of acute pain, including pain management, within a healthcare facility. Children aged four to 18 years (inclusive) attending a healthcare facility who experienced acute pain associated with any injury, medical condition or treatment. Children's experiences and perceptions of their acute pain, pain management and expectations of others in managing their pain. Studies on children's experiences of pain in the postoperative context were excluded as a systematic review exploring this phenomenon had previously been published. Studies reporting on children's experiences of chronic pain were also excluded. Any healthcare facility including general practitioners' surgeries, hospitals, emergency departments and outpatient clinics. Qualitative studies including phenomenology, grounded theory, ethnography, action research and feminist research designs. Using a three-step search strategy, databases were searched in December 2015 to identify both published and unpublished articles from 2000 to 2015. Studies published in languages other than English were excluded. All studies that met the inclusion criteria were assessed by at least two independent reviewers for methodological quality using a standardized critical appraisal tool from the Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI). Data were extracted from the papers included in the review using standardized data extraction tool from JBI-QARI. Findings were pooled using JBI-QARI. Findings were rated according to their level of credibility and categorized based on similarity in meaning and then were subjected to a meta-synthesis. Four studies were included in this review. Two meta-syntheses were generated from five categories based on 21 findings: first, children can express their pain experiences in terms of cause, location, meaning and quality. Children's pain experiences include both physical and psychological dimensions. Children's pain experiences are influenced by their previous pain experiences, pain expectations and sociocultural factors. Second, children use a range of cognitive/behavioral and sensory/physical self-soothing strategies not only to help manage their pain, but also rely on the actions and presence of others as helpers when they are in pain. Children's pain is a multi-dimensional complex phenomenon relying upon a multi-modal approach to management. Children as young as four years are capable of articulating their pain in terms of location, intensity and depth. The way children perceive, express and respond to pain is shaped by sociocultural factors, previous pain experiences and their expectations of pain. Children, parents and healthcare professionals play an important role in managing children's pain experiences.

1993-01-01

The solar array module plasma interactions experiment (SAMPIE) is an approved NASA flight experiment manifested for Shuttle deployment in early 1994. The SAMPIE experiment is designed to investigate the interaction of high voltage space power systems with ionospheric plasma. To study the behavior of solar cells, a number of solar cell coupons (representing design technologies of current interest) will be biased to high voltages to measure both arcing and current collection. Various theories of arc suppression will be tested by including several specially modified cell coupons. Finally, SAMPIE will include experiments to study the basic nature of arcing and current collection. This paper describes the rationale for a space flight experiment, the measurements to be made, and the significance of the expected results. A future paper will present a detailed discussion of the engineering design.

Call, Nathan A; Wacker, David P; Ringdahl, Joel E; Cooper-Brown, Linda J; Boeiter, Eric W

2004-01-01

Several studies have shown that various factors can influence noncompliance, including task novelty, rate of presentation, and task preference. This study examined the impact of selected antecedent variables on noncompliance in an outpatient clinic setting. In two experiments involving 6 typically developing children, the consequences for noncompliance remained constant. During Experiment 1, demands that included noncontingent access to adult attention were contrasted with the same demands that did not include attention within a multielement design. In Experiment 2, demands were altered by decreasing the difficulty or amount of work or providing access to attention. In both experiments, results indicated idiosyncratic responses to the manipulated variables, with decreases in noncompliance observed following introduction of one or more antecedent variables with 5 of the 6 participants. These results suggested that noncompliance can be reduced via changes in antecedent variables, including adding potential positive reinforcers to the task situation, and that it is possible to probe variables that alter noncompliance in an outpatient clinic setting.

To review the qualitative literature on experiences of and preferences for end-of-life care of people with cancer aged 16-40 years (young adults) and their informal carers. A systematic review using narrative synthesis of qualitative studies using the 2006 UK Economic and Social Research Council research methods program guidance. Seven electronic bibliographic databases, two clinical trials databases, and three relevant theses databases were searched from January 2004 to October 2015. Eighteen articles were included from twelve countries. The selected studies included at least 5% of their patient sample within the age range 16-40 years. The studies were heterogeneous in their aims, focus, and sample, but described different aspects of end-of-life care for people with cancer. Positive experiences included facilitating adaptive coping and receiving palliative home care, while negative experiences were loss of "self" and nonfacilitative services and environment. Preferences included a family-centered approach to care, honest conversations about end of life, and facilitating normality. There is little evidence focused on the end-of-life needs of young adults. Analysis of reports including some young adults does not explore experience or preferences by age; therefore, it is difficult to identify age-specific issues clearly. From this review, we suggest that supportive interventions and education are needed to facilitate open and honest communication at an appropriate level with young people. Future research should focus on age-specific evidence about the end-of-life experiences and preferences for young adults with cancer and their informal carers.

Possession experiences in dissociative identity disorder: a preliminary study.

PubMed

Ross, Colin A

2011-01-01

Dissociative trance disorder, which includes possession experiences, was introduced as a provisional diagnosis requiring further study in the Diagnostic and Statistical Manual of Mental Disorders (4th ed.). Consideration is now being given to including possession experiences within dissociative identity disorder (DID) in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.), which is due to be published in 2013. In order to provide empirical data relevant to the relationship between DID and possession states, I analyzed data on the prevalence of trance, possession states, sleepwalking, and paranormal experiences in 3 large samples: patients with DID from North America; psychiatric outpatients from Shanghai, China; and a general population sample from Winnipeg, Canada. Trance, sleepwalking, paranormal, and possession experiences were much more common in the DID patients than in the 2 comparison samples. The study is preliminary and exploratory in nature because the samples were not matched in any way.

2007-01-01

A growing number of studies have been conducted that explore the breast cancer experiences of women from diverse ethnocultural groups. To advance knowledge and provide a foundation for future research, a synthesis was conducted of 15 qualitative research studies focusing on women from ethnocultural groups diagnosed with breast cancer. A qualitative meta-study approach was used that included analysis of the theoretical orientations and methodological approaches underlying the research, and an interpretive synthesis of research findings. Ethnocultural groups represented in the studies included Asian American, Aboriginal, Hispanic, and African American women. The synthesis revealed diverse experiences within and among these ethnocultural groups represented in 5 major themes: (a) the "othered" experience of a breast cancer diagnosis, (b) the treatment experience as "other," (c) losses associated with breast cancer, (d) the family context of breast cancer experiences, and (e) coping with cancer through spirituality and community involvement. The integration of findings from the 15 studies also revealed how methodological and theoretical approaches to conducting this research influenced understandings of the experiences of breast cancer. Further experiential breast cancer research with ethnocultural groups is needed, as well as the use of research methods that illuminate the ways that ethnicity, class, age, and gender relations are played out in healthcare settings.

The relationship between young adulthood, women and psychosis was the focus for this systematic review. Age and gender are factors that can influence responses to illness. Research indicates that there are differences in how young men and women are affected biologically and psychosocially, including the presentation of a constellation of symptoms, response to anti-psychotic medications and how they assess their life circumstances. Yet in literature that examines experiences of young people with psychosis, the specific needs of young women are usually not presented separately. To better understand and address young adult women's healthcare and social service needs, a synthesis of evidence addressing the relationship between young adulthood, women and psychosis is needed. The aim of this systematic review was to synthesize the best available evidence on the experiences of young adult women (aged 18-35 years) living with a psychotic illness in the community. Specifically, the review question was:What are the experiences of young adult women living with a psychotic illness? Participants were young women between 18 and 35 years of age who were living with a psychotic illness in the community. The phenomenon of interest was the experiences of living with a psychotic illness of women aged 18-35 years in the community. Experiences were defined broadly as and inclusive of perceptions and experiences with health and social systems. The context for this review was the community setting. The current review included studies that focused on qualitative data including, but not limited to, designs such as phenomenology, grounded theory, ethnography, action research, feminist research and the qualitative component of mixed methods studies. A three-step search strategy was used to locate both published and unpublished studies. The search was limited to studies published from 1995 to the search date of May 13, 2015. Two reviewers independently appraised the nine included studies using the Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI) assessment tool. Data were extracted from included papers using the standardized data extraction tool from JBI-QARI. Two reviewers independently reviewed the extracted findings to identify potential categories to pool similar findings. A third member of the team met with the reviewers to collaboratively review these derived categories to create a meta-synthesis that reflected a comprehensive set of synthesized findings. Based on the thematic findings from nine qualitative studies, two synthesized findings were identified: (1) the complexity of living with psychosis and finding health, and (2) the presence of harming and healing relationships in young women's lives. The included studies explored a range of experiences relevant for women within the broader phenomenon of experiences of living with a psychotic illness, including experiences within healthcare and social systems. The systematic exploration of the literature resulted in identification of nine studies of moderate-to-high methodological quality that met the inclusion criteria. The ConQual evaluation of the level of evidence resulted in synthesized finding 1 (the complexity of living with psychosis and finding health) rated as moderate and synthesized finding 2 (the presence of harming and healing relationships in young women's lives) rated as low. Practitioners can use these findings to guide practice. Further research exploring other experiences relevant for this population is needed.

Critical interpretive synthesis of barriers and facilitators to TB treatment in immigrant populations.

To systematically review studies of TB treatment experiences in immigrant populations, using Critical Interpretive Synthesis (CIS). On 26 October 2014, MEDLINE, CINAHL, Embase, LILACS, and PsycINFO were systematically searched. Grey literature and reference lists were hand-searched. Initial papers included were restricted to studies of immigrant patient perspectives; after a model was developed, a second set of papers was included to test the emerging theory. Of 1761 studies identified in the search, a total of 29 were included in the synthesis. Using those studies, we developed a model that suggested treatment experiences were strongly related to the way both individuals and societies adjusted to immigration ('acculturation strategies'). Relationships with healthcare workers and immigration policies played particularly significant roles in TB treatment. This review emphasised the roles of repatriation policy and healthcare workers in forming experiences of TB treatment in immigrant populations. © 2017 John Wiley & Sons Ltd.

The impact of negative childbirth experience on future reproductive decisions: A quantitative systematic review.

The aim of this study was to systematically retrieve, critique and synthesize available evidence regarding the association between negative childbirth experiences and future reproductive decisions. A child's birth is often a joyous event; however, there is a proportion of women who undergo negative childbirth experiences that have long-term implications on their reproductive decisions. A systematic review of quantitative studies was undertaken using Joanna Briggs Institute's methods. A search was carried out in CINAHL Plus with Full Text, Embase, PsycINFO, PubMed, Scopus and Web of Science from January 1996 - July 2016. Studies that fulfilled the inclusion criteria were assessed by two independent reviewers using the Joanna Briggs Institute's Critical Appraisal Tools. Data were extracted under subheadings adapted from the institute's data extraction forms. Twelve studies, which examined either one or more influences of negative childbirth experiences, were identified. The included studies were either cohort or cross-sectional designs. Five studies observed positive associations between prior negative childbirth experiences and decisions to not have another child, three studies found positive associations between negative childbirth experiences and decisions to delay a subsequent birth and six studies concluded positive associations between negative childbirth experiences and maternal requests for caesarean section in subsequent pregnancies. To receive a holistic understanding on negative childbirth experiences, a suitable definition and validated measuring tools should be used to understand this phenomenon. Future studies or reviews should include a qualitative component and/or the exploration of specific factors such as cultural and regional differences that influence childbirth experiences. © 2018 John Wiley & Sons Ltd.

Gas-Grain Simulation Facility (GGSF). Volume 1: Stage 1 facility definition studies

Gat, Nahum

1993-01-01

The Gas-Grain Simulation Facility (GGSF) is a facility-type payload to be included in the Space Station Freedom (SSF). The GGSF is a multidisciplinary facility that will accommodate several classes of experiments, including exobiology, planetary science, atmospheric science, and astrophysics. The physical mechanisms envisioned to be investigated include crystal growth, aggregation, nucleation, coagulation, condensation, collisions, fractal growth, cycles of freezing and evaporation, scavenging, longevity of bacteria, and more. TRW performed a Phase A study that included analyses of the science and technical (S&T) requirements, the development of facility functional requirements, and a conceptual design of the facility. The work that was performed under Stage 1 of the Phase A study and the results to date are summarized. In this stage, facility definition studies were conducted in sufficient detail to establish the technical feasibility of the candidate strawman experiments. The studies identified technical difficulties, identified required facility subsystems, surveyed existing technology studies and established preliminary facility weight, volume, power consumption, data systems, interface definition, and crew time requirements. The results of this study served as the basis for Stage 2 of the Phase A study in which a conceptual design and a reference design were performed. The results also served as a basis for a related study for a Gas-Grain Simulation Experiment Module (GGSEM), which is an apparatus intended to perform a subset of the GGSF experiments on board a low-Earth-orbiting platform.

Science and engineering students' classroom experiences: An analysis by gender and discipline

NASA Astrophysics Data System (ADS)

Barrett, Martha Cohen

Based on a concern about the persistence of women in science-related disciplines, this study sought to determine whether science and engineering students' classroom experiences and the importance students attributed to their experiences differed by gender and discipline. Using Chickering & Gamson's (1987) "Seven Principles for Good Practice in Undergraduate Education" as a framework, students' classroom experiences were separated into eight broad categories: Student Preparation, Feedback to Students, Instructor's Expectations of Students, Active Learning, Student Interaction, Instructor's Response to Differences Among Students, Student-Faculty Contact, and Learning Experiences. A survey instrument that included questions related to the eight broad classroom experience dimensions was used to collect data on students' classroom experiences and values in 22 undergraduate biology, chemistry, and mechanical engineering classrooms in a total of three institutions. Most of the classes were sophomore/junior level, and the number of students in each of the classes varied. 896 surveys met the study criteria and were included in the analyses. A total of 23 indices were created using the data collected in the study. Although there were no significant differences in how men and women perceived instructors' classroom behaviors, there were differences in the extent to which men and women reported that they valued particular classroom experiences. For each of these differences (importance of preparation, importance of requirements, importance of cooperative environment, importance of diversity flexibility, and importance of familiarity and respect), women valued the experience more highly than did men. There were also differences in classroom experiences and in the extent to which students valued their experiences across the three disciplines, with more disciplinary differences in students' classroom experiences than in the value they attached to their experiences. While some of the variables included in the study, such as size of class, encouragement from teachers, and expected grade, accounted for a portion of the reported differences in students' experiences and the importance they attached to their experiences, gender and discipline did not add much to the overall understanding of differences in experiences and values.

Adverse childhood experiences are significant risk factors for physical and mental illnesses in adulthood. Traumatic brain injury/concussion is a challenging condition where pre-injury factors may affect recovery. The association between childhood adversity and traumatic brain injury/concussion has not been previously reviewed. The research question addressed is: What is known from the existing literature about the association between adverse childhood experiences and traumatic brain injury/concussion in adults? All original studies of any type published in English since 2007 on adverse childhood experiences and traumatic brain injury/concussion outcomes were included. The literature search was conducted in multiple electronic databases. Arksey and O'Malley and Levac et al.'s scoping review frameworks were used. Two reviewers independently completed screening and data abstraction. The review yielded six observational studies. Included studies were limited to incarcerated or homeless samples, and individuals at high-risk of or with mental illnesses. Across studies, methods for childhood adversity and traumatic brain injury/concussion assessment were heterogeneous. A positive association between adverse childhood experiences and traumatic brain injury occurrence was identified. The review highlights the importance of screening and treatment of adverse childhood experiences. Future research should extend to the general population and implications on injury recovery. Implications for rehabilitation Exposure to adverse childhood experiences is associated with increased risk of traumatic brain injury. Specific types of adverse childhood experiences associated with risk of traumatic brain injury include childhood physical abuse, psychological abuse, household member incarceration, and household member drug abuse. Clinicians and researchers should inquire about adverse childhood experiences in all people with traumatic brain injury as pre-injury health conditions can affect recovery.

Predictions of Cockpit Simulator Experimental Outcome Using System Models

Sorensen, J. A.; Goka, T.

1984-01-01

This study involved predicting the outcome of a cockpit simulator experiment where pilots used cockpit displays of traffic information (CDTI) to establish and maintain in-trail spacing behind a lead aircraft during approach. The experiments were run on the NASA Ames Research Center multicab cockpit simulator facility. Prior to the experiments, a mathematical model of the pilot/aircraft/CDTI flight system was developed which included relative in-trail and vertical dynamics between aircraft in the approach string. This model was used to construct a digital simulation of the string dynamics including response to initial position errors. The model was then used to predict the outcome of the in-trail following cockpit simulator experiments. Outcome included performance and sensitivity to different separation criteria. The experimental results were then used to evaluate the model and its prediction accuracy. Lessons learned in this modeling and prediction study are noted.

The Contradictions of Telehealth User Experience in Chronic Obstructive Pulmonary Disease (COPD): A Qualitative Meta-Synthesis.

2015-01-01

As the global burden of chronic disease rises, policy makers are showing a strong interest in adopting telehealth technologies for use in long term condition management, including COPD. However, there remain barriers to its implementation and sustained use. To date, there has been limited qualitative investigation into how users (both patients/carers and staff) perceive and experience the technology. We aimed to systematically review and synthesise the findings from qualitative studies that investigated user perspectives and experiences of telehealth in COPD management, in order to identify factors which may impact on uptake. Systematic review and meta-synthesis of published qualitative studies of user (patients, their carers and clinicians) experience of telehealth technologies for the management of Chronic Obstructive Pulmonary Disease. ASSIA, CINAHL, Embase, Medline, PsychInfo and Web of Knowledge databases were searched up to October 2014. Reference lists of included studies and reference lists of key papers were also searched. Quality appraisal was guided by an adapted version of the CASP qualitative appraisal tool. 705 references (after duplicates removed) were identified and 10 papers, relating to 7 studies were included in the review. Most authors of included studies had identified both positive and negative experiences of telehealth use in the management of COPD. Through a line of argument synthesis we were able to derive new insights from the data to identify three overarching themes that have the ability to either impede or promote positive user experience of telehealth in COPD: the influence on moral dilemmas of help seeking-(enables dependency or self-care); transforming interactions (increases risk or reassurance) and reconfiguration of 'work' practices (causes burden or empowerment). Findings from this meta-synthesis have implications for the future design and implementation of telehealth services. Future research needs to include potential users at an earlier stage of telehealth/service development.

Scientific thinking is a predicate for scientific inquiry, and thus important to develop early in psychology students as potential future researchers. The present research is aimed at fathoming the contributions of formal and informal learning experiences to psychology students’ development of scientific thinking during their 1st-year of study. We hypothesize that informal experiences are relevant beyond formal experiences. First-year psychology student cohorts from various European countries will be assessed at the beginning and again at the end of the second semester. Assessments of scientific thinking will include scientific reasoning skills, the understanding of basic statistics concepts, and epistemic cognition. Formal learning experiences will include engagement in academic activities which are guided by university authorities. Informal learning experiences will include non-compulsory, self-guided learning experiences. Formal and informal experiences will be assessed with a newly developed survey. As dispositional predictors, students’ need for cognition and self-efficacy in psychological science will be assessed. In a structural equation model, students’ learning experiences and personal dispositions will be examined as predictors of their development of scientific thinking. Commonalities and differences in predictive weights across universities will be tested. The project is aimed at contributing information for designing university environments to optimize the development of students’ scientific thinking. PMID:28239363

Unhealthy lifestyles are a major factor in the development and exacerbation of many chronic diseases. Improving lifestyles though immersive residential experiences that promote healthy behaviours is a focus of the health retreat industry. This systematic review aims to identify and explore published studies on the health, wellbeing and economic impact of retreat experiences. MEDLINE, CINAHL and PsychINFO databases were searched for residential retreat studies in English published prior to February 2017. Studies were included if they were written in English, involved an intervention program in a residential setting of one or more nights, and included before-and-after data related to the health of participants. Studies that did not meet the above criteria or contained only descriptive data from interviews or case studies were excluded. A total of 23 studies including eight randomised controlled trials, six non-randomised controlled trials and nine longitudinal cohort studies met the inclusion criteria. These studies included a total of 2592 participants from diverse geographical and demographic populations and a great heterogeneity of outcome measures, with seven studies examining objective outcomes such as blood pressure or biological makers of disease, and 16 studies examining subjective outcomes that mostly involved self-reported questionnaires on psychological and spiritual measures. All studies reported post-retreat health benefits ranging from immediately after to five-years post-retreat. Study populations varied widely and most studies had small sample sizes, poorly described methodology and little follow-up data, and no studies reported on health economic outcomes or adverse effects, making it difficult to make definite conclusions about specific conditions, safety or return on investment. Health retreat experiences appear to have health benefits that include benefits for people with chronic diseases such as multiple sclerosis, various cancers, HIV/AIDS, heart conditions and mental health. Future research with larger numbers of subjects and longer follow-up periods are needed to investigate the health impact of different retreat experiences and the clinical populations most likely to benefit. Further studies are also needed to determine the economic benefits of retreat experiences for individuals, as well as for businesses, health insurers and policy makers.

Sensory experiences of children with autism spectrum disorder: In their own words

Kirby, Anne V; Dickie, Virginia A; Baranek, Grace T

2015-01-01

First-person perspectives of children with autism spectrum disorder (ASD) are rarely included in research, yet their voices may help more clearly illuminate their needs. This study involved phenomenological interviews with children with ASD (n=12, ages 4-13) used to gain insights about their sensory experiences. This article addresses two study aims: determining the feasibility of interviewing children with ASD and exploring how they share information about their sensory experiences during the qualitative interview process. With the described methods, children as young as four and across a broad range of autism severity scores successfully participated in the interviews. The manner with which children shared information about their sensory experiences included themes of normalizing, storytelling, and describing responses. The interviews also revealed the importance of context and the multisensory nature of children's experiences. These findings contribute strategies for understanding the sensory experiences of children with ASD with implications for practice and future research. PMID:24519585

Current assessments of adverse childhood experiences (ACEs) may not adequately encompass the breadth of adversity to which low-income urban children are exposed. The purpose of this study was to identify and characterize the range of adverse childhood experiences faced by young adults who grew up in a low-income urban area. Focus groups were conducted with young adults who grew up in low-income Philadelphia neighborhoods. Using the nominal group technique, participants generated a list of adverse childhood experiences and then identified the 5 most stressful experiences on the group list. The most stressful experiences identified by participants were grouped into a ranked list of domains and subdomains. Participants identified a range of experiences, grouped into 10 domains: family relationships, community stressors, personal victimization, economic hardship, peer relationships, discrimination, school, health, child welfare/juvenile justice, and media/technology. Included in these domains were many but not all of the experiences from the initial ACEs studies; parental divorce/separation and mental illness were absent. Additional experiences not included in the initial ACEs but endorsed by our participants included single-parent homes; exposure to violence, adult themes, and criminal behavior; personal victimization; bullying; economic hardship; and discrimination. Gathering youth perspectives on childhood adversity broadens our understanding of the experience of stress and trauma in childhood. Future work is needed to determine the significance of this broader set of adverse experiences in predisposing children to poor health outcomes as adults.

Kashbour, W A; Rousseau, N S; Ellis, J S; Thomason, J M

2015-07-01

To identify and summarise the findings of previous qualitative studies relating to patients' experience of dental implant treatment (DIT) at various stages of their implant treatment, by means of textual narrative synthesis. Original articles reporting patients' experience with dental implant were included. A two-stage search of the literature, electronic and hand search identified relevant qualitative studies up to July 2014. An extensive electronic search was conducted of databases including PubMed, Embase, Scopus, Web of Knowledge, Cochrane Database and Google Scholar. Included primary studies (n=10) used qualitative research methods and qualitative analysis to investigate patients' experiences with dental implants treatment. While the growing interest in implant treatment for the replacement of missing dentition is evident, it is essential to investigate patients' perceptions of different aspects of implant treatment. This textual narrative synthesis conducted to review qualitative studies which provided insight into patients' experience of two types of implant prostheses namely ISOD (implant-supported overdenture) and FISP (fixed implant supported prostheses). Primary reviewed studies tended to include samples of older patients with more extensive tooth loss, and to focus on experiences prior to and post-treatment rather than on the treatment period itself. Findings across reviewed studies (n=10) suggested that patients with FISP thought of implant treatment as a process of 'normalisation'(1) and believed that such implant restorations could be similar to natural teeth, whereas patients with ISOD focused more on the functional and social advantages of their implant treatment. The growing interest in qualitative research is evident in several branches of clinical dentistry and dental implantology is not an exception. Qualitative studies concerning the patients account of their experience of dental implants is however limited. The aim of this review is to firstly identify recent work within this field and to subsequently categorise it more consistently by means of textural narrative synthesis, thus highlighting similarities and differences and enabling identification of gaps in research knowledge thereby setting the direction of further research.

The experience of patients with ABI and their families during the hospital stay: A systematic review of qualitative literature.

PubMed

Oyesanya, Tolu

2017-01-01

Patients with acquired brain injury (ABI) and their families have unique experiences and needs during the hospital stay; yet, limited literature exists on this topic. The purpose of this systematic review was to compile and synthesize literature on the experience of patients with ABI and their families during the hospital stay. A systematic review of qualitative studies was conducted by searching for studies from seven databases. Content analysis was used to analyse and synthesize studies' findings separately for the patient and family experience. The initial search provided 2871 records. Ultimately, 11 studies relevant to the research question were included in this review. No studies were excluded based on critical quality appraisal. Findings on the patient experience showed patients had negative perceptions of the rehabilitation environment and a perceived need for information. Findings on the family experience included difficulty adjusting after the patient's injury, a desire to be involved in the patient's care, mixed feelings about staff support and a high perceived need for information. Findings provide awareness for healthcare providers on the multifaceted experiences of patients with ABI and their families during the hospital stay, strategies to make care more patient- and family-centred and directions for future research.

2017-08-01

The stigma of non-communicable respiratory diseases (NCRDs), whether perceived or otherwise, can be an important element of a patient's experience of his/her illness and a contributing factor to poor psychosocial, treatment and clinical outcomes. This systematic review examines the evidence regarding the associations between stigma-related experiences and patient outcomes, comparing findings across a range of common NCRDs. Electronic databases and manual searches were conducted to identify original quantitative research published to December 2015. Articles focussing on adult patient samples diagnosed with asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis, lung cancer or mesothelioma, and included a measurement of stigma-related experience (i.e. perceived stigma, shame, blame or guilt), were eligible for inclusion. Included articles were described for study characteristics, outcome scores, correlates between stigma-related experiences and patient outcomes and methodological rigor. Twenty-five articles were eligible for this review, with most ( n = 20) related to lung cancer. No articles for cystic fibrosis were identified. Twenty unique scales were used, with low to moderate stigma-related experiences reported overall. The stigma-related experiences significantly correlated with all six patient-related domains explored (psychosocial, quality of life, behavioral, physical, treatment and work), which were investigated more widely in COPD and lung cancer samples. No studies adequately met all criteria for methodological rigor. The inter-connectedness of stigma-related experiences to other aspects of patient experiences highlight that an integrated approach is needed to address this important issue. Future studies should adopt more rigorous methodology, including streamlining measures, to provide robust evidence.

Systematic reviews of health systems research commonly limit studies for evidence synthesis to randomized controlled trials. However, well-conducted quasi-experimental studies can provide strong evidence for causal inference. With this article, we aim to stimulate and inform discussions on including quasi-experiments in systematic reviews of health systems research. We define quasi-experimental studies as those that estimate causal effect sizes using exogenous variation in the exposure of interest that is not directly controlled by the researcher. We incorporate this definition into a non-hierarchical three-class taxonomy of study designs - experiments, quasi-experiments, and non-experiments. Based on a review of practice in three disciplines related to health systems research (epidemiology, economics, and political science), we discuss five commonly used study designs that fit our definition of quasi-experiments: natural experiments, instrumental variable analyses, regression discontinuity analyses, interrupted times series studies, and difference studies including controlled before-and-after designs, difference-in-difference designs and fixed effects analyses of panel data. We further review current practices regarding quasi-experimental studies in three non-health fields that utilize systematic reviews (education, development, and environment studies) to inform the design of approaches for synthesizing quasi-experimental evidence in health systems research. Ultimately, the aim of any review is practical: to provide useful information for policymakers, practitioners, and researchers. Future work should focus on building a consensus among users and producers of systematic reviews regarding the inclusion of quasi-experiments. Copyright © 2015 Elsevier Ireland Ltd.

Medical education experiences, particularly in clinical years, are reported determinants of career choice. Less is known about features of clinical education experiences including length, discipline, setting and choice, which may serve as landmarks in career choice decisions. This study's purpose was to explore the benefits of a free choice clerkship elective, and more specifically, its role in clarifying career choice. Using framework and content analysis methodology, we analysed University of British Columbia, third-year medical student anonymised assignments regarding free choice and 2-week clerkship elective experiences. This clerkship was designed to provide students with clerkship experiences outside the conventional curricular model, while encouraging student choice of ambulatory and community settings. Assignment questions included: reasons for choosing elective; whether learning objectives were met; influence of elective on career choice; and unique elective experiences. Iterative review, coding, analysis and indexing of assignments were carried out to identify themes and corroborate findings. Emergent themes included: positive views of experience; transferable knowledge and skills; and influencer of future education and career choices. Although students were encouraged to choose clerkship experiences outside the conventional curricular model, most students chose the elective to clarify future career decisions. This qualitative descriptive study highlights the influence of highly regarded, free choice clerkship elective experiences in the career decision making process in medical education. Further examination of the details of clerkship elective experiences which influence career choice is recommended.

Luker, Julie; Lynch, Elizabeth; Bernhardsson, Susanne; Bennett, Leanne; Bernhardt, Julie

2015-09-01

To report and synthesize the perspectives, experiences, and preferences of stroke survivors undertaking inpatient physical rehabilitation through a systematic review of qualitative studies. MEDLINE, CINAHL, Embase, and PsycINFO were searched from database inception to February 2014. Reference lists of relevant publications were searched. All languages were included. Qualitative studies reporting stroke survivors' experiences of inpatient stroke rehabilitation were selected independently by 2 reviewers. The search yielded 3039 records; 95 full-text publications were assessed for eligibility, and 32 documents (31 studies) were finally included. Comprehensiveness and explicit reporting were assessed independently by 2 reviewers using the consolidated criteria for reporting qualitative research framework. Discrepancies were resolved by consensus. Data regarding characteristics of the included studies were extracted by 1 reviewer, tabled, and checked for accuracy by another reviewer. All text reported in studies' results sections were entered into qualitative data management software for analysis. Extracted texts were inductively coded and analyzed in 3 phases using thematic synthesis. Nine interrelated analytical themes, with descriptive subthemes, were identified that related to issues of importance to stroke survivors: (1) physical activity is valued; (2) bored and alone; (3) patient-centered therapy; (4) recreation is also rehabilitation; (5) dependency and lack of control; (6) fostering autonomy; (7) power of communication and information; (8) motivation needs nurturing; and (9) fatigue can overwhelm. The thematic synthesis provides new insights into stroke survivors' experiences of inpatient rehabilitation. Negative experiences were reported in all studies and include disempowerment, boredom, and frustration. Rehabilitation could be improved by increasing activity within formal therapy and in free time, fostering patients' autonomy through genuinely patient-centered care, and more effective communication and information. Future stroke rehabilitation research should take into account the experiences and preferences of stroke survivors. Copyright © 2015 American Congress of Rehabilitation Medicine.

Some Recent Observations on the Burning of Isolated N-Heptane and Alcohol Droplets

NASA Technical Reports Server (NTRS)

Dryer, F. L.

1999-01-01

In a joint program involving Prof F.A. Williams of the University of California, San Diego and Dr. Vedha Nayagam of the National Center for Microgravity Research on Fluid and Combustion, the combustion of liquid fuel droplets having initial diameters between about 1 mm and 6 mm is being studied. The objectives of the work are to improve fundamental knowledge of droplet combustion dynamics through microgravity experiments and theoretical analyses. The Princeton contributions to the collaborative program supports the engineering design, data analysis, and data interpretation requirements for the study of initially single component, spherically symmetric, isolated droplet combustion studies through experiments and numerical modeling. The complementary UCSD contributions apply asymptotic theoretical analyses and are described in the published literature and in a companion communication in this volume. Emphases of the Princeton work are on the study of simple alcohols (methanol, ethanol), alcohol/water mixtures, and pure alkanes (n-heptane, n-decane) as fuels, with time dependent measurements of drop size, flame-stand-off, liquid-phase composition, and finally, extinction. Ground based experiments have included bench-scale studies at Princeton and collaborative experimental studies in the 2.2 and 5.18 second drop towers at NASA-Glenn Research Center. Spacelab studies have included fiber-supported droplet combustion (FSDC) experiments in the Glovebox facility with accompanying numerical analyses. Experiments include FSDC-1, performed on the USML-2 mission in October, 1995 (STS-73) and FSDC-2, on the second flight of the MSL-1 mission in July, 1997 (STS-94).

“I can’t tell whether it’s my hand”: a pilot study of the neurophenomenology of body representation during the rubber hand illusion in trauma-related disorders

PubMed Central

Rabellino, Daniela; Harricharan, Sherain; Frewen, Paul A.; Burin, Dalila; McKinnon, Margaret C.; Lanius, Ruth A.

2016-01-01

Background Early traumatic experiences are thought to be causal factors in the development of trauma-related dissociative experiences, including depersonalization and derealization. The rubber hand illusion (RHI), a well-known paradigm that measures multi-sensorial integration of a rubber hand into one’s own body representation, has been used to investigate alterations in the experience of body ownership and of body representation. Critically, however, it has never been studied in individuals with trauma-related disorders. Objective To investigate body representation distortions occurring in trauma-related disorders in response to the RHI. Method The RHI was administered to three individuals with the dissociative subtype of posttraumatic stress disorder (PTSD), and subjective, behavioral, cardiovascular and skin conductance responses were recorded. Results Participants’ subjective experiences of the RHI were differentiated and complex. The illusion was induced following both synchronous and asynchronous brushing and variably evoked subjective distress, depersonalization and derealization experiences, tonic immobility, increased physiological arousal and flashbacks. Conclusions The present findings point towards the RHI as a strong provocation stimulus that elicits individual patterns of symptom presentation, including experiences of distress and dissociation, in individuals with trauma-related disorders, including the dissociative subtype of PTSD. Highlights of the article The rubber hand illusion (RHI) elicits distress, tonic immobility, depersonalization and derealization, and autonomic responses in individuals with trauma-related disorders, including the dissociative subtype of posttraumatic stress disorder (PTSD). RHI effects related to body misrepresentation may trigger altered experiences related to body ownership. The RHI represents a promising paradigm for studying the neurophenomenology of body distortion in individuals experiencing trauma-related altered states of consciousness (TRASC). PMID:27876453

Experiences of Physical Therapists Working in the Acute Hospital Setting: Systematic Review.

PubMed

Lau, Bonnie; Skinner, Elizabeth H; Lo, Kristin; Bearman, Margaret

2016-09-01

Physical therapists working in acute care hospitals require unique skills to adapt to the challenging environment and short patient length of stay. Previous literature has reported burnout of clinicians and difficulty with staff retention; however, no systematic reviews have investigated qualitative literature in the area. The purpose of this study was to investigate the experiences of physical therapists working in acute hospitals. Six databases (MEDLINE, CINAHL Plus, EMBASE, AMED, PsycINFO, and Sociological Abstracts) were searched up to and including September 30, 2015, using relevant terms. Studies in English were selected if they included physical therapists working in an acute hospital setting, used qualitative methods, and contained themes or descriptive data relating to physical therapists' experiences. Data extraction included the study authors and year, settings, participant characteristics, aims, and methods. Key themes, explanatory models/theories, and implications for policy and practice were extracted, and quality assessment was conducted. Thematic analysis was used to conduct qualitative synthesis. Eight articles were included. Overall, study quality was high. Four main themes were identified describing factors that influence physical therapists' experience and clinical decision making: environmental/contextual factors, communication/relationships, the physical therapist as a person, and professional identity/role. Qualitative synthesis may be difficult to replicate. The majority of articles were from North America and Australia, limiting transferability of the findings. The identified factors, which interact to influence the experiences of acute care physical therapists, should be considered by therapists and their managers to optimize the physical therapy role in acute care. Potential strategies include promotion of interprofessional and collegial relationships, clear delineation of the physical therapy role, multidisciplinary team member education, additional support staff, and innovative models of care to address funding and staff shortages. © 2016 American Physical Therapy Association.

Naumann, Robert J. (Compiler)

1999-01-01

Some of the 36 Spacelab missions were more or less dedicated to specific scientific disciplines, while other carried a eclectic mixture of experiments ranging from astrophysics to life sciences. However, the experiments can be logically classified into two general categories; those that make use of the Shuttle as an observing platform for external phenomena (including those which use the Shuttle in an interactive mode) and those which use the Shuttle as a microgravity laboratory. This first volume of this Spacelab Science Results study will be devoted to experiments of the first category. The disciplines included are Astrophysics, Solar Physics, Space Plasma Physics, Atmospheric Sciences, and Earth Sciences. Because of the large number of microgravity investigations, Volume 2 will be devoted to Microgravity Sciences, which includes Fluid Physics, Combustion Science, Materials Science, and Biotechnology, and Volume 3 will be devoted to Space Life Sciences, which studies the response and adaptability of living organisms to the microgravity environment.

Student Reflection Papers on a Global Clinical Experience: A Qualitative Study.

PubMed

Margolis, Carmi Z; Rohrbaugh, Robert M; Tsang, Luisa; Fleischer, Jennifer; Graham, Mark J; Kellett, Anne; Hafler, Janet P

Many of the 70,000 graduating US medical students [per year] have reported participating in a global health activity at some stage of medical school. This case study design provided a method for understanding the student's experience that included student's learning about culture, health disparities, exposure and reaction to a range of diseases actually encountered. The broad diversity of themes among students indicated that the GCE provided a flexible, personalized experience. We need to understand the student's experience in order to help design appropriate curricular experiences [and valid student assessment]. Our research aim was to analyze medical student reflection papers to understand how they viewed their Global Clinical Experience (GCE). A qualitative case study design was used to analyze student reflection papers. All 28 students who participated in a GCE from 2008-2010 and in 2014-2015 and submitted a reflection paper on completion of the GCE were eligible to participate in the study. One student did not submit a reflection paper and was not included in the study. All 27 papers were coded by paragraph for reflection and for themes. System of Care/Range of Care was mentioned most often, Aids to Adjustment Process was mentioned least. The theme, "Diseases," referred to any mention of a disease in the reflection papers, and 44 diseases were mentioned in the papers. The analysis for depth of reflection yielded the following data: Observation, 81/248 paragraphs; Observation and Interpretation, 130/248 paragraphs; and Observation, Interpretation, and Suggestions for change, 36/248 paragraphs; 9 reflection papers contained 27 separate accounts of a transformational experience. This study provided a method for understanding the student's experience that included student's learning about culture, health disparities, and exposure and reaction to a range of diseases actually encountered. The broad diversity of themes among students indicated that the GCE provided a flexible, personalized experience. How we might design a curriculum to facilitate transformational learning experiences needs further research. Copyright © 2017 Icahn School of Medicine at Mount Sinai. Published by Elsevier Inc.

Gazza, Elizabeth A; Shellenbarger, Teresa

2010-01-01

Hiring part-time nursing faculty may impact students, faculty careers, and the institution. Yet, little has been studied, particularly in nursing, regarding the experiences of these faculty. This hermeneutic phenomenological study seeks to understand the lived experience of being a part-time faculty member in a baccalaureate nursing program. Through purposive and snowball sampling, nine nursing faculty in part-time positions in northeastern baccalaureate nursing programs participated in in-depth personal interviews. Four themes were uncovered during data analysis, including achieving the dream, a group divided, for the love of the students, and jump in and figure it out. Results of the study seem to indicate that the experience of being a part-time faculty differs in several ways from being a full-time faculty. Understanding part-time faculty experiences provides insight into faculty needs, issues, and concerns while facilitating the development of research-based recruitment and retention strategies. Recommendations for those involved in nursing education, including nursing faculty and administrators, are provided. Copyright © 2010 Elsevier Inc. All rights reserved.

2018-06-05

On 5 and 6 December 2017, the National Institutes of Health (NIH) convened the Pathways to Prevention Workshop: Methods for Evaluating Natural Experiments in Obesity to identify the status of methods for assessing natural experiments to reduce obesity, areas in which these methods could be improved, and research needs for advancing the field. This article considers findings from a systematic evidence review on methods for evaluating natural experiments in obesity, workshop presentations by experts and stakeholders, and public comment. Research gaps are identified, and recommendations related to 4 key issues are provided. Recommendations on population-based data sources and data integration include maximizing use and sharing of existing surveillance and research databases and ensuring significant effort to integrate and link databases. Recommendations on measurement include use of standardized and validated measures of obesity-related outcomes and exposures, systematic measurement of co-benefits and unintended consequences, and expanded use of validated technologies for measurement. Study design recommendations include improving guidance, documentation, and communication about methods used; increasing use of designs that minimize bias in natural experiments; and more carefully selecting control groups. Cross-cutting recommendations target activities that the NIH and other funders might undertake to improve the rigor of natural experiments in obesity, including training and collaboration on modeling and causal inference, promoting the importance of community engagement in the conduct of natural experiments, ensuring maintenance of relevant surveillance systems, and supporting extended follow-up assessments for exemplar natural experiments. To combat the significant public health threat posed by obesity, researchers should continue to take advantage of natural experiments. The recommendations in this report aim to strengthen evidence from such studies.

The experience of patients with ABI and their families during the hospital stay: A systematic review of qualitative literature

Oyesanya, Tolu

2017-01-01

Background Patients with acquired brain injury (ABI) and their families have unique experiences and needs during the hospital stay; yet, limited literature exists on this topic. The purpose of this systematic review was to compile and synthesize literature on the experience of patients with ABI and their families during the hospital stay. Methods A systematic review of qualitative studies was conducted by searching for studies from seven databases. Content analysis was used to analyze and synthesize studies’ findings separately for the patient and family experience. Results The initial search provided 2,871 records. Ultimately, eleven studies relevant to the research question were included in this review. No studies were excluded based on critical quality appraisal. Findings on the patient experience showed patients had negative perceptions of the rehabilitation environment and a perceived need for information. Findings on the family experience included difficulty adjusting after the patient’s injury, desire to be involved in the patient’s care, mixed feelings about staff support, and high perceived need for information. Conclusions Findings provide awareness for healthcare providers on the multifaceted experiences of patients with ABI and their families during the hospital stay, strategies to make care more patient- and family-centered, and directions for future research.

Experiences and perceptions of sexual harassment in the Canadian forces combat arms.

PubMed

Gill, Ritu; Febbraro, Angela R

2013-02-01

Recent studies examining sexual harassment in the military indicate a decrease in reports of harassment, which may be attributed to several factors, including zero-tolerance policies or anti-harassment programs. However, the decrease may also be attributed to fears of losing one's job or of being derogated by colleagues if harassment is reported. This qualitative study of women employed in the Canadian combat arms examined spontaneously shared perceptions and experiences of sexual harassment. Six of the 26 women interviewed shared their experiences or perceptions of harassment, including concerns about potential repercussions of reporting. Implications for gender integration in military organizations are discussed.

Systematic searches for literature published between January 2000 and December 2015 using the databases: SCOPUS, Web of Science, Medline, PsychINFO, Social Policy and Practice and CINAHL. Studies were included if they were published in the English language and were qualitative in design, focussing on the motivations and experiences of staff engaged in part-time, accredited, higher education study. Three reviewers appraised the quality of the selected studies. Thirteen qualitative studies were identified for the review. Motivating factors for staff to engage in part-time, accredited, continuing professional development study included: personal and professional drivers, influence of workplace/management and funding and availability. Key themes in relation to how staff experienced study included: the demands of adjusting to the academic requirements of higher education study; the experience of juggling competing demands of study, work and family; and the presence or absence of support for part-time study in the personal and professional arenas. Health and social care professionals experience a number of challenges when engaging in part-time, continuing professional education in higher education institutions. A significant challenge is the juggling of competing demands of study, work and family, and this may have a negative impact on learning. Research is needed to inform how higher education can address the specific learning needs of this population and develop pedagogic approaches that are both responsive to need and support of effective learning.

NASA Technical Reports Server (NTRS)

Cole, Kevin D.

2003-01-01

The purpose of the project was to investigate methods to accurately verify that designed , materials meet thermal specifications. The project involved heat transfer calculations and optimization studies, and no laboratory experiments were performed. One part of the research involved study of materials in which conduction heat transfer predominates. Results include techniques to choose among several experimental designs, and protocols for determining the optimum experimental conditions for determination of thermal properties. Metal foam materials were also studied in which both conduction and radiation heat transfer are present. Results of this work include procedures to optimize the design of experiments to accurately measure both conductive and radiative thermal properties. Detailed results in the form of three journal papers have been appended to this report.

The EAWE (Examination of Anomalous World Experience) is a newly developed, semi-structured interview that aims to capture anomalies of subjectivity, common in schizophrenia spectrum disorders, that pertain to experiences of the lived world, including space, time, people, language, atmosphere, and certain existential attitudes. By contrast, previous empirical studies of subjective experience in schizophrenia have focused largely on disturbances in self-experience. To assess the reliability of the EAWE, including internal consistency and interrater reliability. In the course of developing the EAWE, two distinct studies were conducted, one in the United States and the other in Slovenia. Thirteen patients diagnosed with schizophrenia spectrum or mood disorders were recruited for the US study. Fifteen such patients were recruited for the Slovenian study. Two live interviewers conducted the EAWE in the US. The Slovenian interviews were completed by one live interviewer with a second rater reviewing audiorecordings of the interview. Internal consistency and interrater reliability were calculated independently for each study, utilizing Cronbach's α, Spearman's ρ, and Cohen's κ. Each study yielded high internal consistency (Cronbach's α >0.82) and high interrater reliability for total EAWE scores (ρ > 0.83; average κ values were at least 0.78 for each study, with EAWE domain-specific κ not lower than 0.73). The EAWE, containing world-oriented inquiries into anomalies in subjective experience, has adequate reliability for use in a clinical or research setting. © 2017 S. Karger AG, Basel.

Nalavany, Blace Arthur; Carawan, Lena Williams; Rennick, Robyn A

2011-01-01

Concept mapping (a mixed qualitative-quantitative methodology) was used to describe and understand the psychosocial experiences of adults with confirmed and self-identified dyslexia. Using innovative processes of art and photography, Phase 1 of the study included 15 adults who participated in focus groups and in-depth interviews and were asked to elucidate their experiences with dyslexia. On index cards, 75 statements and experiences with dyslexia were recorded. The second phase of the study included 39 participants who sorted these statements into self-defined categories and rated each statement to reflect their personal experiences to produce a visual representation, or concept map, of their experience. The final concept map generated nine distinct cluster themes: Organization Skills for Success; Finding Success; A Good Support System Makes the Difference; On Being Overwhelmed; Emotional Downside; Why Can't They See It?; Pain, Hurt, and Embarrassment From Past to Present; Fear of Disclosure; and Moving Forward. Implications of these findings are discussed.

Cimino, Jo Bea; Holt, Benjamin; Richardson, Annie

1988-01-01

The primary objective of the SIR-B experiment was to acquire multiple-incidence-angle radar imagery of a variety of Earth's surfaces to better understand the effects of imaging geometry on radar backscatter. A complementary objective was to map extensive regions of particular interest. Under these broad objectives, many specific scientific experiments were defined by the 43 SIR-B Science Team members, including studies in the area of geology, vegetation, radar penetration, oceanography, image analysis, and calibration technique development. Approximately 20 percent of the planned digital data were collected, meeting 40 percent of the scientific objectives. This report is an overview of the SIR-B experiment and includes the science investigations, hardware design, mission scenario, mission operations, events of the actual missions, astronaut participation, data products (including auxiliary data), calibrations, and a summary of the actual coverage. Also included are several image samples.

Adolescent Perspectives Following Ostomy Surgery: A Grounded Theory Study.

PubMed

Mohr, Lynn D; Hamilton, Rebekah J

2016-01-01

This purpose of this study was to provide a theoretical account of how adolescents aged 13 to 18 years process the experience of having an ostomy. Qualitative study using grounded theory design. The sample comprised of 12 English-speaking adolescents aged 13-18 years: 10 with an ostomy and 2 with medical management of their disease. Respondents completed audio-recorded interviews that were transcribed verbatim. Data were analyzed using the constant comparative method until data saturation occurred. Dedoose, a Web-based qualitative methods management tool, was used to capture major themes arising from the data. Study results indicate that for adolescents between 13 and 18 years of age, processing the experience of having an ostomy includes concepts of the "physical self" and "social self" with the goal of "normalizing." Subcategories of physical self include (a) changing reality, (b) learning, and (c) adapting. Subcategories of social self include (a) reentering and (b) disclosing. This study sheds light on how adolescents process the experience of having an ostomy and how health care providers can assist adolescents to move through the process to get back to their desired "normal" state. Health care providers can facilitate the adolescent through the ostomy experience by being proactive in conversations not only about care issues but also about school and family concerns and spirituality. Further research is needed in understanding how parents process their adolescents' ostomy surgery experience and how spirituality assists adolescents in coping and adjustment with body-altering events.

Scoping studies (or reviews) are a method used to comprehensively map evidence across a range of study designs in an area, with the aim of informing future research practice, programs and policy. However, no universal agreement exists on terminology, definition or methodological steps. Our aim was to understand the experiences of, and considerations for conducting scoping studies from the perspective of academic and community partners. Primary objectives were to 1) describe experiences conducting scoping studies including strengths and challenges; and 2) describe perspectives on terminology, definition, and methodological steps. We conducted a cross-sectional web-based survey with clinicians, educators, researchers, knowledge users, representatives from community-based organizations, graduate students, and policy stakeholders with experience and/or interest in conducting scoping studies to gain an understanding of experiences and perspectives on the conduct and reporting of scoping studies. We administered an electronic self-reported questionnaire comprised of 22 items related to experiences with scoping studies, strengths and challenges, opinions on terminology, and methodological steps. We analyzed questionnaire data using descriptive statistics and content analytical techniques. Survey results were discussed during a multi-stakeholder consultation to identify key considerations in the conduct and reporting of scoping studies. Of the 83 invitations, 54 individuals (65 %) completed the scoping questionnaire, and 48 (58 %) attended the scoping study meeting from Canada, the United Kingdom and United States. Many scoping study strengths were dually identified as challenges including breadth of scope, and iterative process. No consensus on terminology emerged, however key defining features that comprised a working definition of scoping studies included the exploratory mapping of literature in a field; iterative process, inclusion of grey literature; no quality assessment of included studies, and an optional consultation phase. We offer considerations for the conduct and reporting of scoping studies for researchers, clinicians and knowledge users engaging in this methodology. Lack of consensus on scoping terminology, definition and methodological steps persists. Reasons for this may be attributed to diversity of disciplines adopting this methodology for differing purposes. Further work is needed to establish guidelines on the reporting and methodological quality assessment of scoping studies.

Dental hygiene student experiences in external placements in Australia.

Taylor, Jane A; Hayes, Melanie J; Wallace, Linda

2012-05-01

While placements in external locations are being increasingly used in dental education globally, few studies have explored the student learning experience at such placements. The purpose of this study was to investigate student experiences while on external placement in a baccalaureate dental hygiene program. A self-reporting questionnaire was distributed to final-year dental hygiene students (n=77) at the University of Newcastle, Australia, in 2010. The questionnaire included questions regarding the type of placement, experiences offered, supervision, resources available, and lasting impressions. Responding students were generally positive about their external placement experience and indicated that the majority of facilities provided them with the opportunity to provide direct patient care and perform clinical tasks typical of a practicing hygienist. However, there was a statistically significant difference in their opinions about discipline-focused and community placements. Students indicated that their external placement experience provided opportunities to learn more about time and patient management, including hands-on experience with specific clinical tasks. Ongoing evaluations are necessary to ensure that external placements meet both student needs and intended learning outcomes within dental hygiene programs.

"I don't care about you as a person": Sexual minority women objectified.

Tebbe, Elliot A; Moradi, Bonnie; Connelly, Kathleen E; Lenzen, Alexandra L; Flores, Mirella

2018-01-01

This study investigates sexual minority women's experiences of objectification in the United States. Data from 5 focus groups with 33 sexual minority women were analyzed using thematic analysis (Braun & Clarke, 2006, 2012). Results revealed 6 themes and 34 subthemes grouped into "manifestations of objectification: general and explicit intersections," "immediate context of relational and situational characteristics," and "broader context of oppression and privilege along gender and sexualities." First, sexual minority women's experiences of objectification included both general manifestations described in prior research with heterosexual women and manifestations of objectification that reflected intersections of systems of inequality based on sexual orientation, gender identity, race, ethnicity, culture, and age. Second, participants identified novel relational and situational characteristics of objectification. Finally, participants included experiences of stereotyping, discrimination, and dehumanization in their conceptualizations of objectification, connecting their experiences of objectification with broader dynamics of power related to gender and sexuality. Centralizing sexual minority women's experiences, this study produced a fuller understanding of objectification experiences in general and of sexual minority women's experiences in particular.

Rocque, Rhea; Leanza, Yvan

2015-01-01

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

This article describes the roles and experiences of rehabilitation therapists involved in disaster relief work (DRW) in Haiti after the 2010 earthquake. The results of a pilot study and phenomenological study are presented. A phenomenological study of rehabilitation providers' experiences in post-disaster relief care is presented along with preliminary pilot study results. The phenomenological study explored the experiences of therapists from a lived experience perspective through the roles they played in DRW. Participants provided disaster relief through direct patient care, adaptive equipment sourcing and allocation, education and training, community outreach and logistic or administrative duties. Barriers and challenges included: (1) emotions: ups and downs; (2) challenges: working at the edge of practice; (3) education: key to success and sustainability; (4) lessons learned: social responsibility is why we go; and (5) difficulty coming home: no one understands. Therapists play a key role in disaster relief situations. Data presented should encourage organizations to include therapists from early planning to implementation of relief services. Further studies are needed to evaluate the impact of rehabilitation interventions in disaster settings. Understanding the roles and experiences of therapists in disaster relief setting is important Certain barriers to providing care in post-disaster settings exist Those participating in disaster response should be well prepared and aware of that they might be asked to do.

Adults surviving lung cancer two or more years: A systematic review.

PubMed

Rhea, Deborah J; Lockwood, Suzy

Lung cancer has had a low survival rate throughout the years. Some studies have shown that psychological variables such as hardiness and resiliency may play a role in the meaningfulness of survival among lung cancer patients. The objective of this systematic review was to synthesize the best available evidence on the experiences of surviving lung cancer (including psychological/affective well-being dimensions such as resiliency, optimism, quality of life, and coping strategies) in adults over the age of 18, two or more years after diagnosis. The review considered adults (18 years and older) who have survived lung cancer two or more years post diagnosis.The review included studies that examined the experiences (including psychological/affective well-being dimensions such as resiliency, optimism, quality of life, and coping strategies) of surviving lung cancer two or more years post diagnosis.The review considered patients' experiences of surviving lung cancer post two years diagnosis, including the examination of specific psychological/affective well-being aspects such as resiliency, optimism, quality of life and coping strategies.The review included quantitative descriptive studies and qualitative studies. A search for published and unpublished studies in English language from January 1999 through December 2010 was undertaken in multiple databases including MEDLINE, CINAHL, ProQuest and Psyc INFO. Assessment of methodological quality of studies was undertaken using critical appraisal tools from the Joanna Briggs Institute. Data was extracted using the Joanna Briggs Institute Data Extraction forms. Results were presented in a narrative format as the synthesis of qualitative or quantitative data was not appropriate. 13 studies were included in the review: one mixed methods study (including a qualitative research component) and 12 quantitative studies.The qualitative component of the included mixed methods study identified five findings related to the meaningfulness of surviving lung cancer post two years. The central themes that emerged were existential issues, health and self-care, physical ability, adjustment, and support.Quantitative studies identified that distressed groups had less meaningful experiences related to lung cancer survival than not distressed groups. The studies also found that emotional states and style of coping were related to the meaningfulness of lung cancer survival. With less emotional distress, seeing the good in everything, adjusting life to fit the changes from lung cancer, and adding physical activity to the daily routine, the life of a lung cancer survivor can be more meaningful. Healthcare providers must assess lung cancer survivors for potential symptom clusters affecting key patient outcomes such as quality of life. Consider introducing interventions to promote light to moderate physical activity in older patients and moderate to vigorous physical activity in younger patients, and ceasing smoking. Teach active coping strategies. There is a need for qualitative research studies exploring the experiences of lung cancer survivors. Further research is recommended on symptom clusters that might impact outcomes such as quality of life.

2017-09-19

To synthesize the recent qualitative literature and identify the integrative themes describing the parenthood experiences of refugees, asylum-seekers and undocumented migrants. We searched seven online databases for the period January 2006 to February 2017. We included English and French published peer-reviewed articles and graduate-level dissertations, which qualitatively examined the parenthood experiences of refugees, asylum-seekers and undocumented migrants. We summarized study characteristics and performed a thematic analysis across the studies. One hundred thirty eight studies met inclusion criteria. All but three were conducted in high-income countries, mainly in the US. Migrants studied were mostly undocumented from Latin America and refugees from Sub-Saharan Africa. Almost all studies (93%) included mothers; about half (47%) included fathers; very few (5%) included extended family members. We identified three integrative themes: 1) experiencing hardship and/or loss in the context of precarious migration and past traumas; 2) building resilience and strength by bridging language, norms and expectations; and 3) living transnationally: obligations, challenges and resources. Each theme contributed to shaping the parenthood experience; the transnationalism theme intersected with the themes on hardship and loss and resilience and strength. More research is needed with fathers, extended family members, asylum-seekers and in the LMIC context. A transnational lens needs to be applied to programs, policies and future research for refugee, asylum-seeker and undocumented migrant parents. Addressing transnational concerns (family separation and reunification), acknowledging transnational resources, fostering a transnational family identity and conducting transnational and longitudinal studies are potentially pivotal approaches for this sub-population of parents.

A focus group study of chiropractic students following international service learning experiences

Boysen, James C.; Salsbury, Stacie A.; Derby, Dustin; Lawrence, Dana J.

2016-01-01

Objective: One objective of chiropractic education is to cultivate clinical confidence in novice practitioners. The purpose of this qualitative study was to describe how participation in a short-term international service learning experience changed perceptions of clinical confidence in senior chiropractic students. Methods: Seventeen senior chiropractic students participated in 4 moderated focus group sessions within 4 months after a clinical educational opportunity held in international settings. Participants answered standard questions on how this educational experience may have changed their clinical confidence. Two investigators performed qualitative thematic analysis of the verbatim transcripts to identify core concepts and supporting themes. Results: The core concept was transformation from an unsure student to a confident doctor. The service learning experience allowed students to deliver chiropractic treatment to patients in a real-world setting, engage in frequent repetitions of technical skills, perform clinical decision-making and care coordination, and communicate with patients and other health professionals. Students described increased clinical confidence in 9 competency areas organized within 3 domains: (1) chiropractic competencies including observation, palpation, and manipulation; (2) clinical competencies including problem solving, clinic flow, and decision-making; and (3) communication competencies, including patient communication, interprofessional communication, and doctor–patient relationship. Students recommended that future service learning programs include debriefing sessions similar to the experience offered by these focus groups to enhance student learning. Conclusion: Senior chiropractic students who participated in an international service learning program gained confidence and valuable practical experience in integrating their chiropractic, clinical, and communication skills for their future practices.

Stroke patients' involvement in the rehabilitation process including decision making has made significant advances clinically over the past two decades. However, development of patient-focused interventions in stroke rehabilitation is a relatively under developed area of research. The aim of this study was to interpret the explanations that patients gave of their experience after stroke and how these may validate an already established patient-focused intervention framework - the Quest for quality and improved performance (QQUIP) (2006) that includes seven quality improvement goals. A random purposive sample of eight stroke patients was interviewed between 3 and 6 months following discharge. Patients' reports of their experience after stroke were obtained using in-dept semi-structured interviews and analysed using Qualitative Content Analysis. Explanations given by patients included both positive and negative reports of the stroke experience. Regardless of consequences as a result of physical, psychological and social impairments, there were other life style disruptions that were reported by all patients such as taking new medication and adverse effects of these, experiencing increasing fatigue, difficulties with social activities and situations and having to make changes in health behaviours and lifestyle. Some of the core themes that emerged reflected the aims of QQUIP improvement goals that include improving health literacy, clinical decision-making, self-care, patient safety, access to health advice, care experience and service development. Further recommendations based on the findings from this study would be to consider using the QQUIP framework for developing intervention studies in stroke rehabilitation care that are person-centred. This framework provides a template that is equipped to address some of the main concerns that people have following the experience of stroke and also focuses on improving quality of care.

Optimizing the User Experience: Identifying Opportunities to Improve Use of an Inpatient Portal.

PubMed

Walker, Daniel M; Menser, Terri; Yen, Po-Yin; McAlearney, Ann Scheck

2018-01-01

Patient portals specifically designed for the inpatient setting have significant potential to improve patient care. However, little is known about how the users of this technology, the patients, may interact with the inpatient portals. As a result, hospitals have limited ability to design approaches that support patient use of the portal. This study aims to evaluate the user experience associated with an inpatient portal. We used a Think-Aloud protocol to study user interactions with a commercially available inpatient portal-MyChart Bedside (MCB). Study participants included 19 English-speaking adults over the age of 18 years. In one-on-one sessions, participants narrated their experience using the MCB application and completing eight specific tasks. Recordings were transcribed and coded into three dimensions of the user experience: physical, cognitive, and sociobehavioral. Our analysis of the physical experience highlighted the navigational errors and technical challenges associated with the use of MCB. We also found that issues associated with the cognitive experience included comprehension problems that spurred anxiety and uncertainty. Analysis of the sociobehavioral experience suggested that users have different learning styles and preferences for learning including self-guided, handouts, and in-person training. Inpatient portals may be an effective tool to improve the patient experience in the hospital. Moreover, making this technology available to inpatients may help to foster ongoing use of technology across the care continuum. However, deriving the benefits from the technology requires appropriate support. We identified multiple opportunities for hospital management to intervene. In particular, teaching patients to use the application by making a variety of instructional materials available could help to reduce several identified barriers to use. Additionally, hospitals should be prepared to manage patient anxiety and increased questioning arising from the availability of information in the inpatient portal application.

Pharmacist prescribing: A scoping review about the views and experiences of patients and the public.

PubMed

Famiyeh, Ida-Maisie; McCarthy, Lisa

Policy-makers and health professionals' views about pharmacist prescribing have been well studied, but less is known about the views of the public and patients. To describe from existing literature the views and experiences of patients as well as the views of the public about pharmacist prescribing. Sources: Medline, EMBASE, and International Pharmaceutical Abstracts from inception to November 2015; reference lists of included studies. English-language studies describing the views and experiences of patients and the views of the public about pharmacist prescribing. Two reviewers independently screened titles and abstracts and one reviewer charted data. The University of British Columbia Patient Experience Framework was used to categorize and synthesize findings about patients' experience. Views were described using a descriptive thematic synthesis approach. Out of 2377 unique records, 35 articles were reviewed in full for eligibility. Three studies were excluded because participants were not patients or the public, eight studies were not about prescribing, and four studies were abstracts. Two articles were identified from the bibliographies of included studies. In total, twenty-two studies met inclusion criteria. Fourteen studies were quantitative (63.6%), six were qualitative (27.3%) and two were mixed design (9.1%) studies. Four studies (18.2%) were conducted in Canada (Saskatchewan, Newfoundland and Labrador, Nova Scotia), one (4.5%) in Australia, one (4.5%) in the United States (Washington) and the remaining in the United Kingdom (n = 16, 72.7%). The most commonly explored dimensions of patient experiences were access, interpersonal communication, and patient-reported impacts of care. Patients reported high satisfaction with appointment times, communication with the pharmacist prescriber and the services received. The public supported pharmacist prescribing in limited situations (chronic conditions, minor ailments, repeat medications). The public were concerned about privacy during consultations but patients were less so. Both patients and the public shared concerns regarding lack of adequate resources to ensure safe prescribing by pharmacists (e.g., lack of pharmacists' access to medical records, lack of additional staff support to fulfill prescribing responsibilities). Patients' experiences with pharmacist prescribing were generally positive. There were shared concerns between patients and the public about pharmacist prescribing. Opportunities for further research include strategies for building public experience with pharmacist prescribing and methods for addressing concerns identified by patients and the public.

The Continuity of Care Experience in Australian midwifery education-What have we achieved?

PubMed

Tierney, Olivia; Sweet, Linda; Houston, Don; Ebert, Lyn

2017-06-01

The Continuity of Care Experience is a mandated workplace based component of midwifery education in Australia. Since its inclusion in midwifery clinical education, the pedagogical approaches used across Australia have varied. The purpose of this integrative review is to determine the outcomes of the Continuity of Care Experience as an educational model. A search for relevant research literature was undertaken in 2015 using a range of databases and by examining relevant bibliographies. Articles published in English, which provided information about the outcomes of Continuity of Care Experiences for midwifery education were included. A total of 20 studies were selected. The included studies were primarily exploratory and descriptive. Studies reported the value that both students and women place on the relationship they developed. This relationship resulted in opportunities that enhanced student learning by providing a context in which clinical practice learning was optimized. Challenges identified included managing time and workload pressures for students in relation to the CCE, inconsistencies in academic use of the experience, and variations in how the healthcare system influences the continuity experience. No research was found that reports on the educational model in terms of defining learning objectives and assessment of outcomes. This represents an important omission in mandating this clinical practice model in midwifery curricula without sufficient guidance to unify and maximize learning for students. Research is required to explore the educational intent and assessment methods of the Continuity of Care Experience as an educational model. Copyright © 2016 Australian College of Midwives.

2013-12-01

International exchange training in genetic counseling is increasing, but research examining these experiences is lacking. In this study 309 genetic counseling students and genetic counselors completed an anonymous survey investigating six major research questions: (1) How prevalent are international genetic counseling experiences? (2) What types are pursued and why? (3) What supports and barriers exist? 3) What are the demographic characteristics of individuals accruing international experience? (5) Does international experience promote professional development? and (6) Do genetic counseling students and professionals perceive international experiences as beneficial? Most respondents were Caucasian females born in one of 25 countries. The most prevalent experiences involved either clinical observation or clinical training. Common motivations for pursuing international experience were personal growth, exposure to a different healthcare system, and travel opportunities. Outcomes included professionally-relevant experience and personal growth. Barriers included finances, limited availability of opportunities, and for those without international experience, family responsibilities. Additional findings, practice and training implications, and research recommendations are provided.

Recovery in Psychosis from a Service User Perspective: A Systematic Review and Thematic Synthesis of Current Qualitative Evidence.

PubMed

Wood, L; Alsawy, S

2017-11-29

There is a growing number of qualitative accounts regarding recovery from psychosis from a service user perspective. The aim of this study was to conduct a systematic review of these qualitative accounts. A thematic synthesis was utilised to synthesise and analyse seventeen studies included in the review. Studies were included if they used a qualitative methodology to explore service users' experiences of recovery from psychosis as a primary research question. All included studies were subjected to a quality assessment. The analysis outlined three subordinate themes: the recovery journey, facilitators of recovery (e.g. faith and spirituality, personal agency and hope), and barriers to recovery (e.g. stigma and discrimination, negative effects of mental health services and medication). Recovery is an idiosyncratic process but includes key components which are important to people who experience psychosis. These should be explored within clinical practice.

Sexual Experience in Female Rodents: Cellular Mechanisms and Functional Consequences

PubMed Central

Meisel, Robert L.; Mullins, Amanda J.

2007-01-01

The neurobiology of female sexual behavior has largely focused on mechanisms of hormone action on nerve cells and how these effects translate into the display of copulatory motor patterns. Of equal importance, though less studied, are some of the consequences of engaging in sexual behavior, including the rewarding properties of sexual interactions and how sexual experience alters copulatory efficiency. This review summarizes the effects of sexual experience on reward processes and copulation in female Syrian hamsters. Neural correlates of these sexual interactions include long-term cellular changes in dopamine transmission and postsynaptic signaling pathways related to neuronal plasticity (e.g., dendritic spine formation). Taken together, these studies suggest that sexual experience enhances the reinforcing properties of sexual behavior, which has the coincident outcome of increasing copulatory efficiency in a way that can increase reproductive success.

Family caregivers (broadly defined as family and friends) experience multiple concurrent transitions when caring for a person with advanced cancer. To (a) explore the transition experience of family caregivers caring for persons with advanced cancer living in the community, (b) describe potential triggers for transitions, (c) identify what influences this experience, and (d) develop a conceptual framework of their transition experience. Sandelowski and Barroso's methodology for synthesizing qualitative research included (a) a comprehensive search of empirical literature, (b) quality appraisal of qualitative studies, (c) classification of studies, and (d) synthesis of the findings. Literature was sourced from six electronic data bases. Inclusion criteria were as follows: (a) published qualitative studies (and mixed-method designs) of the caregiving experience of family caregivers of community-living persons with advanced cancer at the end of life, (b) participants (caregivers and care recipients) of 18 years of age and above, (c) studies published in English in any country, and (d) studies published between 2004 and 2014. A total of 72 studies were included in the metasynthesis. Family caregivers experience a "life transition" whereby their lives are permanently altered. The participants described the process of redefining normal which consisted of coming to terms with their situation and connecting with others. Outcomes of these processes were as follows: (a) maintaining a sense of personhood, (b) reframing hope, (c) maintaining self-efficacy, (d) finding meaning, and (e) preparing for the death of their care recipient. The findings provide a framework to guide the development of supportive programs and future research.

Patient experience is an essential component of quality care. Few studies have comprehensively evaluated patient experiences of abortion care. The objectives of this study were to describe women's experiences of abortion care in their own words, and to determine themes across patient experiences. Data for this thematic analysis, a qualitative method that allows for the identification, analysis, and report of patterns or themes within data, come from a larger study of safety and quality of aspiration abortion care across 22 clinical sites. Participants completed an abortion experience survey including fixed choice questions and an open-ended question: "Is there anything you would like to tell us about your experience?" The data were then categorized by responses to another survey question: "Overall, was your experience about, better, or worse than you expected?" A total of 5,214 responses were analyzed. Women reported positive abortion care experiences with the majority of women rating their experience as better than expected (n = 3,600). Two major themes that emerged from the data include clinic- and patient-level factors that impact how patients rate their experiences. Analysis of the responses categorized in the worse than expected group (n = 136) found that women primarily faulted clinic-level factors for their negative experiences, such as pain control and management, and wait time for appointments and in clinic. This analysis highlights specific areas of abortion care that influence patients' experience. The few women who were disappointed by care in the clinic tended to fault readily modifiable clinical factors, and provided suggested areas of improvement to enhance positive experiences related to their abortion care.

Given the obesity pandemic, rigorous methodological approaches, including natural experiments, are needed. To identify studies that report effects of programs, policies, or built environment changes on obesity prevention and control and to describe their methods. PubMed, CINAHL, PsycINFO, and EconLit (January 2000 to August 2017). Natural experiments and experimental studies evaluating a program, policy, or built environment change in U.S. or non-U.S. populations by using measures of obesity or obesity-related health behaviors. 2 reviewers serially extracted data on study design, population characteristics, data sources and linkages, measures, and analytic methods and independently evaluated risk of bias. 294 studies (188 U.S., 106 non-U.S.) were identified, including 156 natural experiments (53%), 118 experimental studies (40%), and 20 (7%) with unclear study design. Studies used 106 (71 U.S., 35 non-U.S.) data systems; 37% of the U.S. data systems were linked to another data source. For outcomes, 112 studies reported childhood weight and 32 adult weight; 152 had physical activity and 148 had dietary measures. For analysis, natural experiments most commonly used cross-sectional comparisons of exposed and unexposed groups (n = 55 [35%]). Most natural experiments had a high risk of bias, and 63% had weak handling of withdrawals and dropouts. Outcomes restricted to obesity measures and health behaviors; inconsistent or unclear descriptions of natural experiment designs; and imperfect methods for assessing risk of bias in natural experiments. Many methodologically diverse natural experiments and experimental studies were identified that reported effects of U.S. and non-U.S. programs, policies, or built environment changes on obesity prevention and control. The findings reinforce the need for methodological and analytic advances that would strengthen evaluations of obesity prevention and control initiatives.

The objective of this study was to identify student, clinical instructor (CI), and environmental characteristics and behaviors that make for positive clinical experiences as perceived by physical therapy students. Nine third-year physical therapist students from entry-level physial therapist education programs around the United States participated in this study. In this phenomenologic study, participants were interviewed using open-ended questions designed to facilitate rich description. Interviews were recorded, transcribed, validated, and analyzed. Themes were identified through collaborative analysis using constant comparative coding. Students described student, CI, and environmental factors and behaviors that contribute to a quality clinical experience, including: the students' demonstration of initiative to prepare for the clinical experience and preparation after clinic hours; the importance of the CI's insight, allowing CIs to ascertain how much guidance to give in order to foster independence in the student; and the clinical environment's ability to welcome a student and provide the student with novel learning experiences. The student descriptions, including positive and negative examples shared by the interviewees, demonstrate essential characteristics that contribute to a positive clinical experience. Many of the factors identified by students can be influenced by student and CI training and preparation prior to the clinical experience.

There is increased clinical and political attention towards integrating general and psychiatric emergency departments (ED). However, research into psychiatric service users' experiences regarding general EDs is limited. To identify and summarize current, qualitative evidence regarding service users' experiences attending EDs. A secondary aim is to apply and test the newly developed CERQual approach to summarizing qualitative review findings. A systematic literature review of five databases based on PRISMA guidelines yielded 3334 unique entries. Screening by title/abstract identified 57 studies and, after full text assessment, nine studies were included. The included studies were critically appraised using CASP. Thematic synthesis was applied for data extraction and identification of findings. The CERQual approach was utilized to assess the confidence of the findings. The results of the review showed moderate confidence in the findings that service users experience meeting caring and judgmental ED staff, and that waiting times and a stressful environment are integral to their ED experiences. In contrast, low-to-very low confidence was seen in the findings that service users experience having their symptoms ignored and that EDs are used due to a lack of alternatives. A companion may improve service users experience and outcome of ED visits. Service users experience stress and discomfort in the ED. Service users highly appreciate knowing staff who can ease the discomfort. Overall, the results of this review speak in favour of integrated EDs where service users' needs are more likely to be recognized and accommodated.

To better understand the experience of venous thromboembolism (VTE) from the points of view of patients with cancer during various stages of the cancer experience. Qualitative, descriptive. Various inpatient and outpatient units of a large urban university-affiliated hospital in Montreal, Quebec, Canada. Purposive sample of 10 participants who were anticipating, had recently undergone, or were currently undergoing cancer treatment and who had received a VTE diagnosis within the past year. Semistructured interviews were transcribed verbatim. Thematic analysis of data revealed themes contributing to understanding the lived experience of VTE during cancer care. The experience of patients with cancer who develop VTE. Patients' initial reaction to VTE included VTE as a life-threat, past experience with VTE, and VTE as the "cherry on the sundae" in light of other cancer-related health issues. Patients' coping with VTE also included three themes: VTE being overshadowed by unresolved cancer-related concerns, VTE as a setback in cancer care, and attitudes about VTE treatment. This study contributes new insight into the experience of patients with cancer who develop VTE. The most salient finding was that patients having no prior VTE knowledge experienced VTE as more challenging. Future studies comparing experiences with VTE across the various stages of cancer care are needed. Study findings suggest that patient education about VTE would be useful for the initial reaction and subsequent coping phases of VTE, thus representing an important target area for nursing intervention.

To analyse rural patients' and their families' experiences of open disclosure and offer recommendations to improve disclosure in rural areas. Retrospective qualitative study based on a subset of 13 semistructured, in-depth interviews with rural patients from a larger dataset. The larger data set form a nationwide, multisite, retrospective-qualitative study that included 100 semistructured, in-depth interviews with 119 patients and family members who were involved in high-severity health care incidents and incident disclosure. The larger study is known as the '100 Patient Stories' study. Interviews were transcribed verbatim and analysed by one analyst (D.P.) for recurrent experiences and concerns. Acute care. A sub-set of 13 of the 100 participants from the '100 Patient Stories' study who identified as experiencing an adverse incident in a rural or regional area. Patients' and family members' perceptions and experiences of health care incident disclosure, as expressed in interviews. Rural patients and clinicians experience additional challenges to metropolitan patients and clinicians in their experiences of health care incidents. These additional barriers include: a lack of resources at small hospitals; delays in diagnosis and transfer; distance between services; and a lack of communication between providers. These challenges impact not only upon how patients and their families experience incidents, but also how open disclosure is implemented. This analysis of 13 of the 100 Patient Stories interviews provides guidance to rural health services on how to conduct open disclosure. © 2014 National Rural Health Alliance Inc.

Patient death is an emotional and demanding experience for nurses, especially for new graduate nurses who are unprepared to deliver end-of-life care. Understanding new graduate nurses' experience of death and dying will inform the design of training programs and interventions for improvements in the quality of care and support of new graduates. To summarize new graduate nurses' experience with patient death by examining the findings of existing qualitative studies. Systematic review methods incorporating meta-synthesis were used. A comprehensive search was conducted in 12 databases from January 1990 to December 2014. All qualitative and mixed-method studies in English and Chinese that explored new graduate nurses' experience of patient death were included. Two independent reviewers selected the studies for inclusion and assessed each study quality. Meta-aggregation was performed to synthesize the findings of the included studies. Five primary qualitative studies and one mix-method study met inclusion and quality criteria. Six key themes were identified from the original findings: emotional experiences, facilitating a good death, support for family, inadequacy on end-of-life care issues, personal and professional growth and coping strategies. New graduate nurses expressed a variety of feelings when faced with patient death, but still they tried to facilitate a good death for dying patients and provide support for their families. The nurses benefited from this challenging encounter though they lacked of coping strategies. Copyright © 2015. Published by Elsevier Ltd.

Mantle P wave travel time tomography of Eastern and Southern Africa: New images of mantle upwellings

NASA Astrophysics Data System (ADS)

Benoit, M. H.; Li, C.; van der Hilst, R.

2006-12-01

Much of Eastern Africa, including Ethiopia, Kenya, and Tanzania, has undergone extensive tectonism, including rifting, uplift, and volcanism during the Cenozoic. The cause of this tectonism is often attributed to the presence of one or more mantle upwellings, including starting thermal plumes and superplumes. Previous regional seismic studies and global tomographic models show conflicting results regarding the spatial and thermal characteristics of these upwellings. Additionally, there are questions concerning the extent to which the Archean and Proterozoic lithosphere has been altered by possible thermal upwellings in the mantle. To further constrain the mantle structure beneath Southern and Eastern Africa and to investigate the origin of the tectonism in Eastern Africa, we present preliminary results of a large-scale P wave travel time tomographic study of the region. We invert travel time measurements from the EHB database with travel time measurements taken from regional PASSCAL datasets including the Ethiopia Broadband Seismic Experiment (2000-2002); Kenya Broadband Seismic Experiment (2000-2002); Southern Africa Seismic Experiment (1997- 1999); Tanzania Broadband Seismic Experiment (1995-1997), and the Saudi Arabia PASSCAL Experiment (1995-1997). The tomographic inversion uses 3-D sensitivity kernels to combine different datasets and is parameterized with an irregular grid so that high spatial resolution can be obtained in areas of dense data coverage. It uses an adaptive least-squares context using the LSQR method with norm and gradient damping.

The patient experience of high technology medical imaging: a systematic review of the qualitative evidence.

PubMed

Munn, Zachary; Jordan, Zoe

When presenting to an imaging department, the person who is to be imaged is often in a vulnerable state, and out of their comfort zone. It is the role of the medical imaging technician to produce a high quality image and facilitate patient care throughout the imaging process. Qualitative research is necessary to better inform the medical imaging technician and to help them to understand the experience of the person being imaged. Some issues that have been identified in the literature include fear, claustrophobia, dehumanisation, and an uncomfortable or unusual experience. There is now a small but worthwhile qualitative literature base focusing on the patient experience in high technology imaging. There is no current qualitative synthesis of the literature on the patient experience in high technology imaging. It is therefore timely and worthwhile to produce a systematic review to identify and summarise the existent literature exploring the patient experience of high technology imaging. To identify the patient experience of high technology medical imaging. Studies that were of a qualitative design that explored the phenomenon of interest, the patient experience of high technology medical imaging. Participants included anyone who had undergone one of these procedures. The search strategy aimed to find both published and unpublished studies, and was conducted over a period from June - September 2010. No time limits were imposed on this search strategy. A three-step search strategy was utilised in this review. All studies that met the criteria were selected for retrieval. They were then assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardised critical appraisal instruments from the Joanna Briggs Institute Qualitative Assessment and Review Instrument. Data was extracted from papers included in the review using the standardised data extraction tool from the Joanna Briggs Institute Qualitative Assessment and Review Instrument. Research findings were pooled using the Qualitative Assessment and Review Instrument. Following the search and critical appraisal processes, 15 studies were identified that were deemed of suitable quality to be included in the review. From these 15 studies, 127 findings were extracted, forming 33 categories and 11 synthesised findings. These synthesised findings related to the patient experience, the emotions they felt (whether negative or positive), the need for support and information, and highlighted the importance of imaging to the patient. The synthesised findings in this review highlight the diverse, unique and challenging ways in which people experience imaging with MRI and CT scanners. All health professionals involved in imaging need to be aware of the different ways each patient may experience imaging, and provide them with ongoing support and information. The implications for practice are derived directly from the results of the meta-synthesis, and each of the 11 synthesised findings. There is still scope for further high methodological qualitative studies to be conducted in this field, particularly in the field of nuclear medicine imaging and Positron Emission Tomography. Further studies may be conducted in certain patient groups, and in certain age ranges. No studies were found assessing the experience of children undergoing high technology imaging.

Schreiber, R

2001-01-01

In North America, rates of depression for women are consistently higher than for men. This phenomenon is poorly understood; nonetheless, the use of grounded theory to investigate women's experiences with depression, treatment, and recovery revealed some unexpected findings. In this article I discuss findings resulting from examination of data from three grounded theory studies of women and depression. In all, data were collected through participant observation and more than 70 interviews and the study sample included participants varying in race, marital status, cultural background, and sexual orientation between 18 to 69 years of age, and included both mothers and nonmothers. Findings included the presence in women of an internal dialogue, reinforcing the philosophical origins of the method in symbolic interactionism; oppression and marginalization of women's experiences; the impact of violence in women's lives; the roles of treatment and learning; and the hope of recovery. I will finish by identifying some questions arising from the findings.

The experience of critically ill children: A phenomenological study of discomfort and comfort.

Emerging evidence indicates that critically ill children are particularly at risk for incurring significant psychological harm. Little is known about these children's actual experiences. The aim of the study was to examine children's experience of critical illness. The research question was: What are a critically ill child's sources of discomfort and comfort? Interpretive phenomenology was selected as the study's method. Children's accounts were examined to identify what they considered meaningful, in terms of their experienced discomfort and comfort. Data sources included formal and informal interviews with child-participants, drawings provided by some participants, and field-notes documenting observed non-verbal data. Twelve children were enrolled in the study, ranging from 3 to 17years of age; including four girls and eight boys. Although all participants were able to discuss the discomfort and comfort they experienced, they reported difficulties in remembering part or most of their experience. Some participants characterized their Pediatric Intensive Care Unit stay quite favourably or as "not that bad", while some described their experience unfavourably. Diverse types of discomforts were reported, including fears and worries, hurt and pain, invasive interventions, missing significant people, noise, food or eating problems, boredom, physical symptoms, as well as four additional discomforts reported by individual participants. Several sources of comfort were described, including parents, visitors and friends, hospital staff (principally nurses), stuffed animal/favourite blanket, entertainment and play, food, selected medical interventions, thinking of going home, being able to walk or run, sleep, waking up, gifts, along with two other comforts reported by individual participants. Embodiment and a tension between aloneness and being with were identified as the principal phenomena underlying these children's experiences. The findings complement existing knowledge regarding the psychological impact of critical illness by highlighting how children regard specific phenomena as discomforting or comforting. This sheds light on future directions for practice and research development in pediatric critical care.

Barriers to recruitment for research on mental illness include participant distrust of researchers and social stigma. Though these issues may be acutely important in perinatal mental health research, they remain unexplored in this context. In order to inform strategies to more fully engage women in perinatal mental health research, we explored the motivations and experiences of women with a history of major depressive disorder who participated in a prospective longitudinal research study on postpartum depression (PPD). Sixteen women with a history of depression who had either completed or recently made a decision about participation in a longitudinal research study about PPD were interviewed by telephone. Qualitative, semi-structured interviews explored participants' decision-making about, and experiences of, participation. Interviews were audio-recorded, transcribed, and qualitatively analyzed using elements of grounded theory methodology. Follow-up interviews were conducted with four participants to refine and clarify preliminary results. Foundational elements necessary for women to consider participating in PPD research included personal acceptance of illness and trust in the research team/institution. Other main motivators included perceived personal relevance, anticipated benefits (including access to support/resources, learning opportunities, and improved self-worth), altruism, and accessible study procedures. Our data suggest that participating in perinatal mental health research may help women make meaning of their mental illness experience and is perceived as providing support. The findings-particularly around the importance of participant-researcher rapport and accessibility of study design-may inform strategies that improve participation rates, decrease attrition, and maximize participant benefits in perinatal mental health research.

Global engineering education programs: More than just international experiences

NASA Astrophysics Data System (ADS)

McNeill, Nathan J.

Engineers in both industry and academia recognize the global nature of the profession. This has lead to calls for engineering students to develop knowledge, skills, and attitudes necessary for success within a global profession. Many institutions are developing globally oriented programs specifically for their engineering students and are eager to know if these programs are helping their students to develop attributes that meet their program objectives, accreditation requirements, and the needs and desires of prospective employers. Administrators of such programs currently lack research data to support the learning objectives they are setting for their programs. This study documented the individual experiences and learning outcomes of students involved in three global education programs for engineering students. The first program provided a portfolio of experiences including foreign language instruction, one semester of study abroad, internships in the U.S. and abroad, and a two-semester global team design project. The second program was a one semester study abroad program in China, and the third was a global service project whose purpose was to design an irrigation system for two small farms in Rwanda. The research questions guiding this study were: 1. What specific knowledge, skills, and attitudes are students gaining from participation in their respective global engineering programs? 2. What kinds of experiences are resulting in these learning outcomes? Interviews were used to elicit the experiences and learning outcomes of participants in this study. Program administrators were also interviewed for their perspectives on the experiences and learning outcomes of participants for the purpose of triangulation. The study identified more than 50 outcomes that resulted from students' experiences in these three programs. The most prevalent outcomes across all three programs included knowledge of culture, openness to new experiences and other cultures, and communication skills.

Beginning with OSTA-1 in November 1981 and ending with Neurolab in March 1998, a total of 36 Shuttle missions carried various Spacelab components such as the Spacelab module, pallet, instrument pointing system, or mission peculiar experiment support structure. The experiments carried out during these flights included astrophysics, solar physics, plasma physics, atmospheric science, Earth observations, and a wide range of microgravity experiments in life sciences, biotechnology, materials science, and fluid physics which includes combustion and critical point phenomena. In all, some 764 experiments were conducted by investigators from the U.S., Europe, and Japan. The purpose of this Spacelab Science Results Study is to document the contributions made in each of the major research areas by giving a brief synopsis of the more significant experiments and an extensive list of the publications that were produced. We have also endeavored to show how these results impacted the existing body of knowledge, where they have spawned new fields, and if appropriate, where the knowledge they produced has been applied.

The Defense Department and NASA have joined in a program to study the space environment which surrounds the earth and the effects of space radiation on modern satellite electronic systems. The Combined Release and Radiation Effects Satellite (CRRES) will carry an array of active experiments including chemical releases and a complement of sophisticated scientific instruments to accomplish these objectives. Other chemical release active experiments will be performed with sub-orbital rocket probes. The chemical releases will 'paint' the magnetic and electric fields of earthspace with clouds of glowing ions. Earthspace will be a laboratory, and the releases will be studied with an extensive network of ground-, aircraft-, and satellite-based diagnostic instruments. Some of the topics discussed include the following: the effects of earthspace; the need for active experiments; types of chemical releases; the CRRES program schedule; international support and coordinated studies; photographing chemical releases; information on locating chemical releases for observation by the amateur; and CRRES as a program.

A systematic review of the experiences of undergraduate nursing students choosing to study at an English speaking university outside their homeland.

PubMed

Terwijn, Ruth; Pearce, Susanne; Rogers-Clark, Catherine

Increasingly overseas students are attending university nursing programs in English-speaking countries to gain additional tertiary qualifications that may not be available in their homeland and also to fill the international nursing shortfall. For these students, some common issues identified and affirmed in qualitative research papers include loneliness, discriminatory experiences, developing communication, and academic skills. This systematic review will help identify and synthesise current issues through exploring the existing literature, giving an insight into the lives of international nursing students. Given the large and increasing number of these students, it is important to acknowledge and improve learning and other outcomes for them. The objective of this systematic review was to determine the best available evidence in relation to the experiences of undergraduate nursing students choosing to study at an English speaking university outside their homeland. This review sought high quality studies aimed at exploring the experience of undergraduate nursing students studying outside their homeland at an English speaking university. Both qualitative research studies and opinion-based text were considered for this review. An extensive search of the literature was conducted to identify research studies published between January 1990 and April 2011 in English and indexed in 37 major databases. All included articles were assessed independently by two reviewers (RT and SP), using the appropriate critical appraisal tool from the Joanna Briggs Institute. Data were extracted from included papers using appropriate standardised data extraction tools developed by the Joanna Briggs Institute. Data from qualitative studies and textual and opinion papers were meta-synthesised separately using standardised instruments. Data synthesis of all included studies involved the pooling of findings and then grouping into categories on a basis of similarity of meaning. The categories were further aggregated into a set of statements representing synthesised findings as a coherent whole. A total of 19 studies were identified as of high quality and meeting the inclusion criteria. From these studies, 254 findings were extracted which were grouped into 13 categories and further aggregated into four synthesised findings. The four major areas identified in this review in relation to the experiences of undergraduate nursing students studying outside their homeland at an English-speaking university include the need for support and encouragement, valuing and respecting difference, and the desire to succeed despite challenges and inclusion. Recognising the unique needs of international nursing students, in the clinical, academic and social context, is critical to improve the experiences of this student cohort. Educational and support strategies and programs are needed to respond to these needs. The implications for research are substantial. Given the outcomes of this review, action and evaluative research is needed to explore, implement and evaluate support strategies for students from non-English speaking backgrounds studying nursing. Research in the areas of curriculum development, supporting students' clinical experiences, and university social and academic support programs is recommended.

2011-01-01

The completion of International Space Station Assembly and transition to a full six person crew has created the opportunity to create and implement flight experiments that will drive down the ultimate risks and cost for human space exploration by maturing exploration technologies in realistic space environments that are impossible or incredibly costly to duplicate in terrestrial laboratories. An early opportunity for such a technology maturation experiment was recognized in the amine swingbed technology baselined for carbon dioxide and humidity control on the Orion spacecraft and Constellation Spacesuit System. An experiment concept using an existing high fidelity laboratory swing bed prototype has been evaluated in a feasibility and concept definition study leading to the conclusion that the envisioned flight experiment can be both feasible and of significant value for NASA s space exploration technology development efforts. Based on the results of that study NASA has proceeded with detailed design and implementation for the flight experiment. The study effort included the evaluation of technology risks, the extent to which ISS provided unique opportunities to understand them, and the implications of the resulting targeted risks for the experiment design and operational parameters. Based on those objectives and characteristics, ISS safety and integration requirements were examined, experiment concepts developed to address them and their feasibility assessed. This paper will describe the analysis effort and conclusions and present the resulting flight experiment concept. The flight experiment, implemented by NASA and launched in two packages in January and August 2011, integrates the swing bed with supporting elements including electrical power and controls, sensors, cooling, heating, fans, air- and water-conserving functionality, and mechanical packaging structure. It is now on board the ISS awaiting installation and activation.

Objective To explore men’s lived experience of advanced prostate cancer (PCa) and preferences for support. Design Cross-sectional qualitative study applying open-ended surveys and interviews conducted between June and November 2016. Interviews audio-recorded and transcribed verbatim and analysed from an interpretive phenomenological perspective. Setting Australia, nation-wide. Participants 39 men diagnosed with advanced PCa (metastatic or castration-resistant biochemical progression) were surveyed with 28 men subsequently completing a semistructured in depth telephone interview. Results Thematic analysis of interviews identified two organising themes: lived experience and supportive care. Lived experience included six superordinate themes: regret about late diagnosis and treatment decisions, being discounted in the health system, fear/uncertainty about the future, acceptance of their situation, masculinity and treatment effects. Supportive care included five superordinate themes: communication, care coordination, accessible care, shared experience/peer support and involvement of their partner/family. Conclusions Life course and the health and social context of PCa influence men’s experiences of advanced disease. Multimodal interventions integrating peer support and specialist nurses are needed that more closely articulate with men’s expressed needs. PMID:29455168

Out-of-body experiences associated with seizures

Greyson, Bruce; Fountain, Nathan B.; Derr, Lori L.; Broshek, Donna K.

2014-01-01

Alterations of consciousness are critical factors in the diagnosis of epileptic seizures. With these alterations in consciousness, some persons report sensations of separating from the physical body, experiences that may in rare cases resemble spontaneous out-of-body experiences. This study was designed to identify and characterize these out-of-body-like subjective experiences associated with seizure activity. Fifty-five percent of the patients in this study recalled some subjective experience in association with their seizures. Among our sample of 100 patients, 7 reported out-of-body experiences associated with their seizures. We found no differentiating traits that were associated with patients' reports of out-of-body experiences, in terms of either demographics; medical history, including age of onset and duration of seizure disorder, and seizure frequency; seizure characteristics, including localization, lateralization, etiology, and type of seizure, and epilepsy syndrome; or ability to recall any subjective experiences associated with their seizures. Reporting out-of-body experiences in association with seizures did not affect epilepsy-related quality of life. It should be noted that even in those patients who report out-of-body experiences, such sensations are extremely rare events that do not occur routinely with their seizures. Most patients who reported out-of-body experiences described one or two experiences that occurred an indeterminate number of years ago, which precludes the possibility of associating the experience with the particular characteristics of that one seizure or with medications taken or other conditions at the time.

Smoking is a well-known public health problem in women as well as men. In many countries including Iran, there is an increase in tobacco use among women. Exploring the experience of smoking by educated women in order to develop effective tobacco prevention programs in these women is necessary. This study aimed to explore the experiences of smoking among Iranian educated women. This study used a method of qualitative content analysis with the deep individual, semi-structured interviews on a sample of 14 educated female smokers, selected purposefully. Data were analyzed using qualitative content analysis with conventional approach while being collected. The data analysis led to 16 subcategories which were divided into four main categories: (1) Personal factors including subcategories of imitation, show-off and independence, inexperience and curiosity, personal interest and desire, improved mood, and social defiance; (2) family factors including smokers in the family, intrafamily conflicts, and family strictures and limitations; (3) social factors including subcategories of effects of work and school environment, gender equality symbols, peer pressure, and acceptance among friends; and (4) negative consequences of smoking including subcategories of a sense of being physically hurt, psychological and emotional stress, and being looked upon in a negative and judgmental manner. The findings of this study showed that smoking among Iranian educated women is a multifactorial problem. Thus, it is necessary to address smoking among educated women in a holistic approach that focuses on different determinants including personal, family, and social factors particularly the gender roles and stereotypes.

From in vivo to in vitro: How the Guatemala STD Experiments Transformed Bodies Into Biospecimens.

PubMed

Spector-Bagdady, Kayte; Lombardo, Paul A

2018-06-01

Policy Points: While most scholarship regarding the US Public Health Service's STD experiments in Guatemala during the 1940s has focused on the intentional exposure experiments, secondary research was also conducted on biospecimens collected from these subjects. These biospecimen experiments continued after the Guatemala grant ended, and the specimens were used in conjunction with those from the Tuskegee syphilis experiments for ongoing research. We argue there should be a public accounting of whether there are still biospecimens from the Guatemala and Tuskegee experiments held in US government biorepositories today. If such specimens exist, they should be retired from US government research archives because they were collected unethically as understood at the time. The US Public Health Service's Guatemala STD experiments (1946-1948) included intentional exposure to pathogens and testing of postexposure prophylaxis methods for syphilis, gonorrhea, and chancroid in over 1,300 soldiers, commercial sex workers, prison inmates, and psychiatric patients. Though the experiments had officially ended, the biospecimens collected from these subjects continued to be used for research at least into the 1950s. We analyzed historical documents-including clinical and laboratory records, correspondence, final reports, and medical records-for information relevant to these biospecimen experiments from the US National Archives. In addition, we researched material from past governmental investigations into the Guatemala STD experiments, including those of the US Presidential Commission for the Study of Bioethical Issues and the Guatemalan Comisión Presidencial para el Esclarecimiento de los Experimentos Practicados con Humanos en Guatemala. Identified spinal fluid, blood specimens, and tissue collected during the Guatemala diagnostic methodology and intentional exposure experiments were subsequently distributed to laboratories throughout the United States for use in ongoing research until at least 1957. Five psychiatric patient subjects involved in these biospecimen experiments died soon after experimental exposure to STDs. The same US government researchers working with the Guatemala biospecimens after the exposure experiments ended were also working with specimens taken from the Tuskegee syphilis study. There should be a complete public accounting of whether biospecimens from the Guatemala and Tuskegee experiments are held in US government biorepositories today. If they still exist, these specimens should be retired from such biorepositories and their future disposition determined by stakeholders, including representatives from the communities from which they were derived. © 2018 Milbank Memorial Fund.

Mental models at work: cognitive causes and consequences of conflict in organizations.

PubMed

Halevy, Nir; Cohen, Taya R; Chou, Eileen Y; Katz, James J; Panter, A T

2014-01-01

This research investigated the reciprocal relationship between mental models of conflict and various forms of dysfunctional social relations in organizations, including experiences of task and relationship conflicts, interpersonal hostility, workplace ostracism, and abusive supervision. We conceptualize individual differences in conflict construals as reflecting variation in people's belief structures about conflict and explore how different elements in people's associative networks-in particular, their beliefs about their best and worst strategy in conflict-relate to their personality, shape their experiences of workplace conflict, and influence others' behavioral intentions toward them. Five studies using a variety of methods (including cross-sectional surveys, a 12-week longitudinal diary study, and an experiment) show that the best strategy beliefs relate in theoretically meaningful ways to individuals' personality, shape social interactions and relationships significantly more than the worst strategy beliefs, and are updated over time as a result of individuals' ongoing experiences of conflict.

Meanings of Falls and Prevention of Falls According to Rehabilitation Nurses: A Qualitative Descriptive Study.

PubMed

Bok, Amy; Pierce, Linda L; Gies, Cheryl; Steiner, Victoria

2016-01-01

Guided by Friedemann's theoretical framework, this survey explored the meaning of a fall of an institutionalized older adult or fall prevention to rehabilitation registered nurses and whether the experience changed the nurse's practice. Qualitative, descriptive survey. A convenience sample of 742 rehabilitation nurses was asked to describe these experiences and the impact on their practice. Themes discovered related to the meaning of a fall include negative feelings (incongruence) and positive feelings (congruence). Themes related to the meaning of preventing a fall include positive feelings (congruence). Practice change themes emerged from both the experience of a fall and fall prevention. Practice change themes were drawn to Friedemann's (1995) process dimensions. Nurses' experiences and meanings of falls uncovered negative and positive feelings about these falls. New findings of this study were the positive feelings expressed by nurses, when there was no injury or when a fall was prevented. © 2015 Association of Rehabilitation Nurses.

McLemore, Monica R; Altman, Molly R; Cooper, Norlissa; Williams, Shanell; Rand, Larry; Franck, Linda

2018-03-01

Chronic stress is a known risk factor for preterm birth, yet little is known about how healthcare experiences add to or mitigate perceived stress. In this study, we described the pregnancy-related healthcare experiences of 54 women of color from Fresno, Oakland, and San Francisco, California, with social and/or medical risk factors for preterm birth. This study was a secondary analysis of focus group data generated as part of a larger project focused on patient and community involvement in preterm birth research. English and Spanish speaking women, age 18 or greater with social and/or medical risk factors for preterm birth participated in two focus groups, six weeks apart. Data from the first focus groups are included in this analysis. Five themes emerged from thematic analysis of the transcripts. Participants described disrespect during healthcare encounters, including experiences of racism and discrimination; stressful interactions with all levels of staff; unmet information needs; and inconsistent social support. Despite these adverse experiences, women felt confidence in parenting and newborn care. Participant recommendations for healthcare systems improvement included: greater attention to birth plans, better communication among multiple healthcare providers, more careful listening to patients during clinical encounters, increased support for social programs such as California's Black Infant Health, and less reliance on past carceral history and/or child protective services involvement. The women in this study perceived their prenatal healthcare as a largely disrespectful and stressful experience. Our findings add to the growing literature that women of color experience discrimination, racism and disrespect in healthcare encounters and that they believe this affects their health and that of their infants.

Wilkes, Donald R.; Zwiener, James M.

1999-01-01

Long term stability of spacecraft materials when exposed to the space environment continues to be a major area of investigation. The natural and induced environment surrounding a spacecraft can decrease material performance and limit useful lifetimes. The Optical Properties Monitor (OPM) experiment provided the capability to perform the important flight testing of materials and was flown on the Russian Mir Station to study the long term effects of the natural and induced space environment on materials. The core of the OPM in-flight analysis was three independent optical instruments. These instruments included an integrating sphere spectral reflectometer, a vacuum ultraviolet spectrometer, and a Total Integrated Scatter instrument. The OPM also monitored selected components of the environment including molecular contamination. The OPM was exposed on the exterior of the Mir Docking Module for approximately 8-1/2 months. This report describes the OPM experiment, a brief background of its development, program organization, experiment description, mission overview including space environment definition, performance overview, materials data including flight and ground data, in-depth post flight analysis including ground analysis measurements and a summary discussion of the findings and results.

2016-01-01

Objectives In countries with ageing populations, home care (HC) aides are among the fastest growing jobs. There are few quantitative studies of HC occupational safety and health (OSH) conditions. The objectives of this study were to: (1) assess quantitatively the OSH hazards and benefits for a wide range of HC working conditions, and (2) compare OSH experiences of HC aides who are employed via different medical and social services systems in Massachusetts, USA. Methods HC aides were recruited for a survey via agencies that employ aides and schedule their visits with clients, and through a labour union of aides employed directly by clients or their families. The questionnaire included detailed questions about the most recent HC visits, as well as about individual aides’ OSH experiences. Results The study population included 1249 HC aides (634 agency-employed, 615 client-employed) contributing information on 3484 HC visits. Hazards occurring most frequently related to musculoskeletal strain, exposure to potentially infectious agents and cleaning chemicals for infection prevention and experience of violence. Client-hired and agency-hired aides had similar OSH experiences with a few exceptions, including use of sharps and experience of verbal violence. Conclusions The OSH experience of HC aides is similar to that of aides in institutional healthcare settings. Despite OSH challenges, HC aides enjoy caring for others and the benefits of HC work should be enhanced. Quantification of HC hazards and benefits is useful to prioritise resources for the development of preventive interventions and to provide an evidence base for policy-setting. PMID:26209318

A summary of measured hydraulic data for the series of steady and unsteady flow experiments over patterned roughness

USGS Publications Warehouse

Collins, Dannie L.; Flynn, Kathleen M.

1979-01-01

This report summarizes and makes available to other investigators the measured hydraulic data collected during a series of experiments designed to study the effect of patterned bed roughness on steady and unsteady open-channel flow. The patterned effect of the roughness was obtained by clear-cut mowing of designated areas of an otherwise fairly dense coverage of coastal Bermuda grass approximately 250 mm high. All experiments were conducted in the Flood Plain Simulation Facility during the period of October 7 through December 12, 1974. Data from 18 steady flow experiments and 10 unsteady flow experiments are summarized. Measured data included are ground-surface elevations, grass heights and densities, water-surface elevations and point velocities for all experiments. Additional tables of water-surface elevations and measured point velocities are included for the clear-cut areas for most experiments. One complete set of average water-surface elevations and one complete set of measured point velocities are tabulated for each steady flow experiment. Time series data, on a 2-minute time interval, are tabulated for both water-surface elevations and point velocities for each unsteady flow experiment. All data collected, including individual records of water-surface elevations for the steady flow experiments, have been stored on computer disk storage and can be retrieved using the computer programs listed in the attachment to this report.

The psychology of volition.

PubMed

Frith, Chris

2013-09-01

Volition can be studied from two perspectives. From the third-person view, volitional behaviour is internally generated, rather than being determined by the immediate environmental context, and is therefore, to some extent, unpredictable. Such behaviour is not unique to humans, since it is seen in many other species including invertebrates. From the first-person view, our experience of volitional behaviour includes a vivid sense of agency. We feel that, through our intentions, we can cause things to happen and we can choose between different actions. Our experience of agency is not direct. It depends on sub-personal inferences derived from prior expectations and sensations associated with movement. As a result, our experiences and intuitions about volition can be unreliable and uncertain. Nevertheless, our experience of agency is not a mere epiphenomenon. Anticipation of the regret we might feel after making the wrong choice can alter behaviour. Furthermore, the strong sense of responsibility, associated with agency, has a critical role in creating social cohesion and group benefits. We can only study the experience of agency in humans who can describe their experiences. The discussion of the experience of volition, that introspection and communication make possible, can change our experience of volitional actions. As a result, agency, regret and responsibility are cultural phenomena that are unique to humans.

The experience of a community characterized by violence: implications for nursing.

PubMed

Madela, E N; Poggenpoel, M

1993-05-01

Social situations make a person vulnerable to mental illness. These situations include circumstances such as poverty, family instability and inadequate nutrition. A combination of these circumstances predisposes exposed people to developing unhealthy ways of coping with stress. Violence is seen as a way of managing stress, but also as a factor causing stress. An example of unhealthy ways of stress management in the current South African society is the violence that leads to unrest which has affected different communities in a short space of time. The aim of this study was to explore the experience of a community exposed to violence and to identify implications for nursing. An exploratory contextual study was undertaken with the purpose of generating meaning regarding the experience of a community characterized by violence. The phenomenological method of interviewing was used to gather data. The target population consisted of a township community of 228,000. Ten respondents were interviewed in total, selected by the convenience purposive sampling method through intermediaries. The interviews were recorded on tape and later transcribed verbatim. Data were analysed by the method of content analysis. The results were centred on the respondents' and their families' experiences of violence since March 1990. The results indicated four types of experiences for all people exposed to violence: psychological, spiritual, physical and behavioural experiences. The experiences of interactions with the internal environment (psychological, spiritual and physical experience) were predominantly negative, except for only two positive spiritual experiences (improvements in the people's faith and in the employer-employee relationships). On the other hand, experiences of interactions between the internal and external environments, namely behavioural experiences, were both negative and positive. The negative experiences included pretence, thuggery, scapegoating and harassment. The positive experiences included solidarity, bravery and increased appreciation. The presence of positive experiences in both environments brought about new insights; that is, that even though most of their internal environment and part of their external environment is bleak and hopeless, the victims of violence still have the will to survive and live a normal life like other people. This positive attitude supplies the psychiatric nurse with a point of entry to bring about positive change that acts as a support for the community exposed to violence. Possibilities of applying the results of this study in education, practice and research in the health field became evident.

Teaching caring and competence: Student transformation during an older adult focused service-learning course.

PubMed

Brown, Karen M; Bright, Leslie M

2017-11-01

Innovative teaching strategies develop nurses' knowledge, skills, and attitudes while simultaneously integrating the art of caring and transforming attitudes toward adults over age 65. The study's purpose was to explore students' experiences and attitudes toward older adults with cognitive and/or physical limitations as well as the effects on students' knowledge and skills during a baccalaureate nursing, course which included a service-learning experience. Service-learning synthesizes meaningful community service, academic instruction, and reflection. Participants included baccalaureate students enrolled in a service-learning nursing course focused on older adults. This retrospective, qualitative, phenomenological study used reflective journals and an online survey to explore baccalaureate nursing students' experiences toward older adults with cognitive and/or physical limitations. Themes included initial attitudes of anticipation, apprehension, anxiety, and ageist stereotypes. Final attitudes included a "completely changed perspective" of caring, compassion, and respect indicative of a rewarding, "life-changing" experience. Participants cited enhanced learning, especially in the areas of patient-centered care, collaboration, communication, advocacy, empathy, assessment skills, and evidence-based practice. This innovative teaching strategy led to transformed attitudes toward older adults, reduced fear of older adult populations, an increased desire to work with older adults, and the ability to form a transpersonal, caring relationship while enhancing nursing knowledge and skills.

Leininger's Ethnonursing Research Methodology and Studies of Cancer Survivors: A Review.

PubMed

Farren, Arlene T

2015-09-01

The purpose of this article is to present the findings of a literature review regarding the use of Leininger's ethnonursing research methodology (ENRM) in studies addressing adult cancer survivors. It is important to learn about differences and similarities among cancer survivors' experiences so that patient-centered, culturally congruent care can be provided. A review of the literature was conducted using databases such as CINAHL and MEDLINE. Search terms included variations on ENRM and cancer survivors. The results were a small number of published studies that used the ENRM examining breast cancer survivors' perceptions and experiences. A review instrument was developed to estimate study quality based on established criteria. The studies are critiqued in relation to the theory-based methodology, evaluation criteria for qualitative research, and study findings are summarized. The author concludes that although there is a paucity of research using ENRM with adult cancer survivors, the preliminary findings of the included studies contribute to what is known about breast cancer survivors. Implications for research include recommendations to increase the use of ENRM to discover the universal and diverse experiences of care practices in adult cancer survivors and use the evidence to develop patient-centered, culturally congruent, quality care for cancer survivors. © The Author(s) 2014.

1986-01-01

Current plans for the Earth Observing System (EOS) include development of a lidar facility to conduct scientific experiments from a polar orbiting platforms. A recommended set of experiments were scoped, which includes techniques of atmospheric backscatter (Lidar), Differential Absorption Lidar (DIAL), altimetry, and retroranging. Preliminary assessments of the resources (power, weight, volume) required by the Eos Lidar Facility were conducted. A research program in tunable solid state laser technology was developed, which includes laser materials development, modeling and experiments on the physics of solid state laser materials, and development of solid state laser transmitters with a strong focus on Eos scientific investigations. Some of the system studies that were conducted which highlight the payoff of solid state laser technology for the Eos scientific investigations will be discussed. Additionally, a summary of some promising research results which have recently emerged from the research program will be presented.

Negotiating the integration of new literacies in math and science content: The lived experience of classroom teachers

NASA Astrophysics Data System (ADS)

Wimmer, Jennifer Joy

The purpose of this phenomenological study was to investigate the lived experience of integrating new literacies in math and science content by upper elementary and middle school teachers. This study highlights the lived experience of six teachers including two elementary math teachers, two middle school math teachers, and two middle school science teachers. Data sources included five in-depth interviews, teachers' weekly reflection journals, weekly classroom observations, and one principal interview at each of the three high-needs schools. Data were analyzed through an analytic and thematic approach. A reconstructed story was created for each teacher which provides insight into the teacher as an individual. Additionally, a thematic analysis resulted in the identification of five essential themes across all six stories which included: technology exclusively, rethinking who they are as teachers, stabilizing rather than challenging content, rethinking student learning, circumstances, and futures, and serving official context and discourse. The findings indicate that the teachers' lived experience of integrating new literacies in math and science content was filled with uncertainty and a search for stability. A key implication of this study is the need for quality professional development that provides teachers with the opportunity to learn about, question, and rethink the intersection of new literacies, content area literacy, and teacher knowledge.

PubMed

Ferguson, Kristin M

2009-11-01

This qualitative study used data from the Social Enterprise Intervention (SEI) pilot study, a comprehensive vocational training program with integrated clinical services for homeless youth. In-depth interviews were conducted with 28 homeless youth participating in the SEI study to explore their perceptions of family environment characteristics and abuse experiences. The constant comparative method was used to analyze transcripts from in-depth interviews with the youth participants. Emergent themes related to family characteristics include home instability, abandonment, and caregiver substance abuse. Abuse-related subthemes include intrafamilial abuse, caregiver abuse, rejection, and deprecation by caregivers. Grounded theory is used to interpret findings and develop working hypotheses to guide future studies of multitype maltreatment among homeless youth.

The purpose of this study is to support Russian space flight experiments carried out on rats flown aboard Space Shuttle Mission SLS-2. The Russian experiments were designed to determine the effects of space flight on immunological parameters. The Russian experiment included the first in-flight dissection of rodents that allowed the determination of kinetics of when space flight affected immune responses. The support given the Russians by this laboratory was to carry out assays for immunologically important cytokines that could not readily be carried out in their home laboratories. These included essays of interleukin-1, interleukin-6, interferon-gamma and possibly other cytokines.

The situation-specific theory of pain experience for Asian American cancer patients.

PubMed

Im, Eun-Ok

2008-01-01

Studies have indicated the need for theories that explain and target ethnic-specific cancer pain experiences, including those of Asian Americans. In this article, I present a situation-specific theory that explains the unique cancer pain experience of Asian Americans. Unlike other existing theories, this situation-specific theory was developed on the basis of evidence, including a systematic literature review and research findings, making it comprehensive and highly applicable to research and practice with Asian American patients with cancer. Thus, this theory would strengthen the interconnections among theory, evidence, and practice in pain management for Asian American cancer patients.

2017-07-01

African American (AA) adults are disproportionally affected by type 2 diabetes and are diagnosed at an earlier age, but are less adherent to diabetes medications compared with the general population. This qualitative study sought to describe the experiences of taking diabetes medications among midlife AA men and women with type 2 diabetes and to identify factors that influence these experiences. Fifteen AAs completed semistructured interviews. Using the Roy adaptation model, thematic analysis coded for both adaptive and ineffective experiences. Adaptive experiences included self-confidence in one's ability to control diabetes, a belief in the value of diabetes medication, assuming responsibility for one's health, developing a routine for taking medication, and positive relationships with the care team. Ineffective experiences for medication taking included: feeling powerless over diabetes, self-blame, and fear. One's self-concept as a person with diabetes, as well as assuming the role of "medication taker," were prominent themes.

Women living with epilepsy, experiences of pregnancy and reproductive health: a review of the literature.

PubMed

Weckesser, Annalise; Denny, Elaine

2013-03-01

This study aimed to investigate the experiences of pregnancy in women living with epilepsy through a review and synthesis of existing literature. A comprehensive search of the literature was conducted in medical and social science databases to identify qualitative research, and questionnaires that included open-ended questions, which reported on the impact of epilepsy on the lives of pregnant women from preconception to post-delivery. The search was widened to include qualitative studies on pregnancy and issues of reproduction with women living with chronic illness that had at least one woman with epilepsy in the sample. The systematic search, carried out from April to June 2012, identified 17 publications that met the inclusion criteria, and 24 publications that did not. Qualitative results from these studies were categorised into: stage of pregnancy (preconception, pregnancy, and postnatal); case studies of patients' experiences; and the reproductive health experiences of women living with chronic illness. One qualitative study was identified that directly investigated women's experiences of epilepsy during pregnancy. Many of the findings from the 16 remaining publications were found to be limited in generalisability due to small sample sizes and/or the poor quality of data. Qualitative research on women's experiences of pregnancy whilst living with epilepsy is needed to address this critical gap in knowledge. This paper calls for improved preconception, pregnancy and postnatal supports and information for women living with this condition. Copyright © 2012 British Epilepsy Association.

Alsawy, Sarah; Mansell, Warren; McEvoy, Phil; Tai, Sara

2017-11-01

Many strategies have been recommended to support caregivers in communicating with people who live with dementia. However, less is known about what makes communication a good and meaningful experience from the perspective of people with dementia. Understanding this may enhance the person with dementia's sense of connectedness, strengthen their relationships, and facilitate person-centered care. The current review aimed to evaluate research that examined experiences of communication in people living with dementia. Studies that examined reports provided by people with dementia, healthcare professionals, and family caregivers were included. A mixed-methods systematic review was conducted using PsychINFO, MEDLINE, and EMBASE databases. After applying the eligibility criteria, 15 studies were included. Although eight of these recruited people with dementia, only one focused on their perspectives of communication experiences and the remaining studies focused on the perspectives of family caregivers and healthcare professionals. These studies either explored experiences without suggestions of communication methods, "open exploration," or through examining experiences of strategies, "exploration of strategies." A significant theme was around communication difficulties that affected interpersonal relationships and activities of daily living. Conversely, personhood strategies and a strong underlying relationship were believed to facilitate communication. The one study that examined the perspectives of people with dementia emphasized the importance of retaining valued relationships and feeling respected during communication. The need to involve people with dementia in research, particularly around their experiences of communication, is evident. Such research would be imperative for facilitating person-centered care, strengthening social relationships, and informing training programs.

Lorentz and CPT Tests with Atoms

NASA Astrophysics Data System (ADS)

Vargas Silva, Arnaldo J.

The prospects for using atomic-spectroscopy experiments to test Lorentz and CPT symmetry are investigated. Phenomenological models for Lorentz violation studied in this work include ones with contributions from all quadratic operators for a Dirac fermion in the Lagrange density of the Standard-Model Extension (SME), without restriction on the operator mass dimension. The systems considered include atoms composed of conventional matter, antimatter, and second-generation particles. Generic expressions for the Lorentz-violating energy shifts applicable to a broad range of atomic transitions are obtained. Signals for Lorentz violation that can in principle be studied in spectroscopic experiments are identified from the theoretical corrections to the spectrum. Some of these signals include sidereal and annual variations of atomic transition frequencies measured in a laboratory on the surface of the Earth. Other possibilities include effects produced by changing the orientation of the applied magnetic field or by realizing space-based experiments. Discrepancies in the experimental values for fundamental constants and energy levels based on self-consistent predictions from the Standard Model also offer potential signals for Lorentz violation. The sensitivities of different experiments to distinct sets of coefficients for Lorentz violation are considered. Using atoms composed of different particle species allows measurements of coefficients for Lorentz violation in different fermion sectors of the SME. Experiments comparing hydrogen and antihydrogen can discriminate between coefficients for Lorentz violation that are associated with CPT-odd or CPT-even operators. Additionally, certain systems and transitions are more sensitive to nonminimal operators, while others are particularly sensitive to minimal ones.

Influence of Clinical Experience and Productivity on Emergency Medicine Faculty Teaching Scores

PubMed Central

Clyne, Brian; Smith, Jessica L.; Napoli, Anthony M.

2012-01-01

Background Commonly cited barriers to effective teaching in emergency medicine include lack of time, competing demands for patient care, and a lack of formal teaching experience. Teaching may be negatively affected by demands for increased clinical productivity, or positively influenced by clinical experience. Objective To examine the association between faculty teaching scores and clinical productivity, years of clinical experience, and amount of clinical contact with resident physicians. Methods We conducted a retrospective, observational study with existing data on full-time faculty at a high-volume, urban emergency medicine residency training program for academic year 2008–2009. Residents rated faculty on 9 domains of teaching, including willingness to teach, enthusiasm for teaching, medical knowledge, preparation, and communication. Clinical productivity data for relative value units per hour and number of patients per hour, years of clinical experience, and annual clinical hours were obtained from existing databases. Results For the 25 core faculty members included in the study, there was no relationship between faculty teaching scores and clinical productivity measures (relative value units per hour: r2  =  0.01, P  =  .96, patients per hour: r2  =  0.00, P  =  .76), or between teaching scores and total clinical hours with residents (r2  =  0.07, P  =  .19). There was a significant negative relationship between years of experience and teaching scores (r2  =  0.27, P < .01). Conclusions Our study demonstrated that teaching scores for core emergency medicine faculty did not correlate with clinical productivity or amount of clinical contact with residents. Teaching scores were inversely related to number of years of clinical experience, with more experienced faculty earning the lowest teaching scores. Further study is necessary to determine if there are clinical measures that identify good educators. PMID:24294418

Provocative work experiences predict the acquired capability for suicide in physicians.

PubMed

Fink-Miller, Erin L

2015-09-30

The interpersonal psychological theory of suicidal behavior (IPTS) offers a potential means to explain suicide in physicians. The IPTS posits three necessary and sufficient precursors to death by suicide: thwarted belongingness, perceived burdensomeness, and acquired capability. The present study sought to examine whether provocative work experiences unique to physicians (e.g., placing sutures, withdrawing life support) would predict levels of acquired capability, while controlling for gender and painful and provocative experiences outside the work environment. Data were obtained from 376 of 7723 recruited physicians. Study measures included the Acquired Capability for Suicide Scale, the Interpersonal Needs Questionnaire, the Painful and Provocative Events Scale, and the Life Events Scale-Medical Doctors Version. Painful and provocative events outside of work predicted acquired capability (β=0.23, t=3.82, p<0.001, f(2)=0.09) as did provocative work experiences (β=0.12, t=2.05, p<0.05, f(2)=0.07). This represents the first study assessing the potential impact of unique work experiences on suicidality in physicians. Limitations include over-representation of Caucasian participants, limited representation from various specialties of medicine, and lack of information regarding individual differences.

Exploring the views and experiences of HIV positive patients treated for cancer: a systematic review of the literature.

PubMed

Hainsworth, Emma G; Shahmanesh, Maryam; Stevenson, Fiona

2018-05-01

A systematic review of the literature was conducted to find out what is known about patients' experiences of a dual diagnosis of HIV and cancer. We systematically searched the following databases; MEDLINE (Ovid Version); CINAHL Plus; PsycINFO and EMBASE from inception to June 2016 for studies that included patients with a dual diagnosis of cancer and HIV and focused on patient experiences. Studies with a focus on one illness rather than a dual diagnosis, those that focused on treatment strategies and medical management, epidemiology and pathology studies and comparison studies were all excluded. The full text of the included studies were reviewed. Information on location, sample size, study design and a narrative summary of findings were extracted using a standardised format. Studies were combined thematically. 1777 records were screened by title and abstract using the selection criteria described in the methods. Eight records were reviewed in depth in full text and seven selected as eligible. The selected studies suggest that a dual diagnosis of HIV and cancer has a powerful impact on individuals' behaviour. The experience of stigma was a consistent factor in all patient accounts and the strategy of selective disclosure to access support reveals how patient agency can interplay with stigma. This is an area largely unexplored in the published literature; further research into patients' experiences of a dual diagnosis of HIV and cancer will provide relevant knowledge in order to tailor and improve services.

Adverse Childhood Experiences in a Post-bariatric Surgery Psychiatric Inpatient Sample.

PubMed

Fink, Kathryn; Ross, Colin A

2017-12-01

Sixty-three inpatients in a psychiatric hospital who had previously undergone bariatric surgery were interviewed by the hospital dietitian. The purpose of the study was to determine the frequency of adverse childhood experiences in this population. Participants completed the Adverse Childhood Experiences (ACE) Scale. The average score on the ACE was 5.4 (3.3); 76% of participants reported childhood emotional neglect, 70% childhood verbal abuse, and 64% childhood sexual abuse; only two participants reported no adverse childhood experiences. The participants in the study reported high levels of adverse childhood experiences compared to the general population, which is consistent with prior literature on rates of childhood trauma in post-bariatric surgery patients. The role of adverse childhood experiences in post-bariatric surgery adaptation should be investigated in future research, including in prospective studies.

A Thematic Inquiry into the Burnout Experience of Australian Solo-Practicing Clinical Psychologists.

PubMed

Hammond, Trent E; Crowther, Andrew; Drummond, Sally

2017-01-01

Objective: Burnout is conceptualized as a syndrome that consists of emotional exhaustion, depersonalization, and decreased personal accomplishment. Despite the increased frequency and severity of burnout in the Western world, there is limited published research regarding the experiences of clinical psychologists who have had burnout. The present study examines clinical psychologists' different experiences of burnout in Australia. Design and Methods: In the year 2015, six privately practicing and solo-employed clinical psychologists provided rich qualitative data by participating in semi-structured interviews. Thematic analysis was the method used to analyze clinical psychologists' natural accounts of their burnout experiences. Using NVivo, emerging themes were identified through coding 'first order constructs' and then axial code 'second order constructs.' Findings: Clinical psychologists indicated that their roles are demanding and a diverse range of symptoms, including the enduring effects of burnout, mental stress, fatigue, decreased personal accomplishment, negative affect, depersonalization, reduced productivity and motivation, and insomnia. They identified precursors of burnout, including excessive workload and hours of work, life stresses, mismanaged workload, and transference. Clinical psychologists suggested that protective factors of burnout include knowledge and years worked in direct care, and trusting and long-term relationships. They indicated that the barriers to overcoming burnout include the fallacy that their clients' expectations and needs are more important than their own, the financial cost of working in private practice, contemporary knowledge and inadequate education regarding self-care, and time constraints. Discussion and Conclusion: The findings presented in this study provide psychologists and other health professionals with an insight about the burnout experience and inform professionals of the mental shortcomings of working as a solo-practicing clinical psychologist. Findings from this study should lead to an increased understanding of the complexities of burnout, and ultimately reduced cases of burnout, absenteeism, and staff disengagement.

Microgravity is an environment with very weak gravitational effects. The Fluids and Combustion Facility (FCF) on the International Space Station (ISS) will support the study of fluid physics and combustion science in a long-duration microgravity environment. The Fluid Combustion Facility's design will permit both independent and remote control operations from the Telescience Support Center. The crew of the International Space Station will continue to insert and remove the experiment module, store and reload removable data storage and media data tapes, and reconfigure diagnostics on either side of the optics benches. Upon completion of the Fluids Combustion Facility, about ten experiments will be conducted within a ten-year period. Several different areas of fluid physics will be studied in the Fluids Combustion Facility. These areas include complex fluids, interfacial phenomena, dynamics and instabilities, and multiphase flows and phase change. Recently, emphasis has been placed in areas that relate directly to NASA missions including life support, power, propulsion, and thermal control systems. By 2006 or 2007, a Fluids Integrated Rack (FIR) and a Combustion Integrated Rack (CIR) will be installed inside the International Space Station. The Fluids Integrated Rack will contain all the hardware and software necessary to perform experiments in fluid physics. A wide range of experiments that meet the requirements of the international space station, including research from other specialties, will be considered. Experiments will be contained in subsystems such as the international standard payload rack, the active rack isolation system, the optics bench, environmental subsystem, electrical power control unit, the gas interface subsystem, and the command and data management subsystem. In conclusion, the Fluids and Combustion Facility will allow researchers to study fluid physics and combustion science in a long-duration microgravity environment. Additional information is included in the original extended abstract.

Socio-Cultural Factors and Experience of Chronic Low Back Pain: a Spanish and Brazilian Patients’ Perspective. A Qualitative Study

PubMed Central

2016-01-01

Background Low back pain (LBP) could be influenced by socio-cultural factors. Pain narratives are important to understand the influence of environment on patients with chronic LBP. There are few studies that have explored the experience of patients with chronic LBP in different socio-cultural environments. The aim of this study was to describe the experience of patients with chronic LBP in Spain and Brazil. Methods A qualitative phenomenology approach was implemented. Chronic LBP patients from the University Hospital of Salamanca (Spain), and/or Federal University of São Carlos (Brazil) were included, using purposeful sampling. Data were collected from 22 Spanish and 26 Brazilian patients during in-depth interviews and using researchers’ field notes and patients' personal diaries and letters. A thematic analysis was performed and the guidelines for reporting qualitative research were applied. Results Forty-eight patients with a mean age of 50.7 years (SD: ± 13.1 years) were included in the study. The themes identified included: a) ways of perceiving and expressing pain—the participants focused constantly on their pain and anything outside it was considered secondary; b) the socio-familial environment as a modulator of pain—most participants stated that no one was able to understand the pain they were experiencing; c) religion as a modulator of pain—all Brazilian patients stated that religious belief affected the experience of pain; and d) socio-economic and educational status as a modulator of pain—the study reported that economic factors influenced the experience of pain. Conclusions The influences of LBP can be determined based on the how a patient defines pain. Religion can be considered as a possible mechanism for patients to manage pain and as a form of solace.

Bax, A C; Shawler, P M; Blackmon, D L; DeGrace, E W; Wolraich, M L

2016-09-01

Factors surrounding pediatricians' parenting advice and training on parenting during residency have not been well studied. The primary purpose of this study was to examine pediatric residents' self-reported experiences giving parenting advice and explore the relationship between parenting advice given and types of parenting residents received as children. Thirteen OUHSC pediatric residents were individually interviewed to examine experiences being parented and giving parenting advice. Phenomenological methods were used to explicate themes and secondary analyses explored relationships of findings based upon Baumrind's parenting styles (authoritative, authoritarian, permissive). While childhood experiences were not specifically correlated to the parenting advice style of pediatric residents interviewed, virtually all reported relying upon childhood experiences to generate their advice. Those describing authoritative parents reported giving more authoritative advice while others reported more variable advice. Core interview themes related to residents' parenting advice included anxiety about not being a parent, varying advice based on families' needs, and emphasis of positive interactions and consistency. Themes related to how residents were parented included discipline being a learning process for their parents and recalling that their parents always had expectations, yet always loved them. Pediatric residents interviewed reported giving family centered parenting advice with elements of positive interactions and consistency, but interviews highlighted many areas of apprehension residents have around giving parenting advice. Our study suggests that pediatric residents may benefit from more general educational opportunities to develop the content of their parenting advice, including reflecting on any impact from their own upbringing.

Summarized are the results of a thorough performance study of Get Away Special (GAS) payloads conducted in 1986. During the study, a complete list of standard and non-standard GAS payloads vs. Shuttle mission was constructed, including specific titles for the experiments in each canister. A broad data base for each canister and each experiment was then compiled. Performance results were then obtained for all but a few experiments. The canisters and experiments were subsequently categorized according to the degree of experiment success. For those experiments experiencing failures or anomalies, several correlations and generalizations were extracted from individual subsystem performance data. Recommendations are made which may enhance the success and performance of future GAS payloads.

Lapidus-Graham, Joanne

2012-01-01

The purpose of this qualitative phenomenological research study was to obtain vivid descriptions of the lived experience of nurses who participated in a student nursing association (SNA) as students. Nursing graduates from five nursing programs in Long Island, New York were identified using a purposive sampling strategy. During individual interviews, the themes of the lived experiences of the participants emerged: (1) leadership: communication, collaboration and resolving conflict, (2) mentoring and mutual support, (3) empowerment and ability to change practice, (4) professionalism, (5) sense of teamwork, and (6) accountability and responsibility. Recommendations from the study included an orientation and mentoring of new students to the SNA by senior students and faculty. Additionally, nursing faculty could integrate SNA activities within the classroom and clinical settings to increase the awareness of the benefits of participation in a student nursing organization. Recommendations for future research include a different sample and use of different research designs.

Methods of particle generation and characterization with regard to their applicability for experiments requiring cloud condensation nuclei (CCN) of specified properties were investigated. Since aerosol characterization is a prerequisite to assessing performance of particle generation equipment, techniques for characterizing aerosol were evaluated. Aerosol generation is discussed, and atomizer and photolytic generators including preparation of hydrosols (used with atomizers) and the evaluation of a flight version of an atomizer are studied.

A history of traumatic and/or stressful experiences is prevalent among HIV-infected individuals and has been consistently associated with poorer health outcomes. However, little is known about incident stressful experiences and the factors that predict these experiences among HIV-infected individuals. Data from a longitudinal study of 611 HIV-infected individuals in the Southeastern US were used to examine the frequency and types of incident stress reported in a 27-month period and to determine predictors associated with 3 incident stress measures (all stressful events, severe stressful events, and traumatic events such as physical assault). Incident stressful experiences frequently occurred among study participants, as 91% reported at least one stressful experience (median= 3.5 experiences) and 10% of study participants reported traumatic stress in any given 9-month reporting period. Financial stressors were the most frequently reported by study participants. Greater emotional distress, substance use, and number of baseline stressful experiences were significantly associated with reporting a greater number of incident stressful experiences and any traumatic experiences. Study results indicate that efforts are needed to identify individuals at risk for traumatic events and/or substantial stressors and to address the factors, including mental health and substance abuse that contribute to these experiences.

2017-04-01

Inter-professional initiatives are prevalent in the healthcare landscape, requiring professionals to collaborate effectively to provide quality patient care. Little attention has been given to intra-professional relationships, where professionals within one disciplinary domain (such as degree and diploma nursing students) collaborate to provide care. New care models are being introduced where baccalaureate and diploma students of a particular discipline (such as nursing, occupational therapy, dentistry or physiotherapy) work closely together in teams to deliver care. Questions thus arise as to how students and educators learn to work on intra-professional teams. To identify and synthesize evidence regarding experiences of pre-licensure health professional students and their educators on intra-professional teams and to draw recommendations to enhance policy and/or curriculum development. Pre-licensure students and educators, focusing on regulated health professions that have had more than one point of entry into practice. Experiences of intra-professional team learning or teaching within various entry-to-practice categories of a particular health-related discipline. Eight qualitative studies were included in the review. Seven studies were descriptive in nature; one study was a critical analysis. A comprehensive search of various databases was conducted between June 2, 2015 and August 16, 2015, and repeated in March 2016. The search considered all studies reported and published from January 1, 2001 to March 7, 2016. Only studies published in English were included in this review. Included papers were of low-to-moderate quality; however, it is important to consider that post-positivist assumptions underpinned much of the primary research, which could explain why researcher positionality and/or influence on the research would not be addressed. Data were extracted using the standardized data extraction tool from the Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI). The data extracted included descriptive details about the phenomenon of interest, populations and study methods. Research findings were pooled using the JBI-QARI. Sixty-eight findings were organized into nine categories based on similarity in meaning. Four synthesized findings reveal how students value intra-professional learning experiences. These experiences build positive collaborative relationships (including trust and respect); however, educator and staff attitudes and conversations create hierarchies in academic and clinical contexts resulting in tension between student groups. Despite its challenges, shared learning experiences assist students to understand each other's roles, develop communication and collaborative competencies, develop comprehensive care plans, provide more efficient care and help prepare them for their future roles as healthcare professionals. Various contextual elements could either hinder or facilitate shared learning experiences.

Most healthcare professionals at some time will experience having a significant other admitted to an acute care hospital. The knowledge and understanding that these individuals possess because of their professional practice can potentially alter this experience. Expectations of staff and other family members (FMs) can potentially increase the burden on these health professionals. All FMs of patients should have their needs and expectations considered; however, this review specifically addresses what may be unique for healthcare professionals. To synthesize the qualitative evidence on the experiences of healthcare professionals when their significant others are admitted to an acute care hospital. The current review considered studies reporting the experiences of healthcare professionals, specifically registered nurses (RNs) and physicians. The experiences of RNs and physicians when a significant other is admitted to an acute care facility. Qualitative studies that have examined the phenomenon of interest including, but not limited to, designs such as phenomenology and grounded theory. The search strategy aimed to find both published and unpublished studies with no date restrictions. Only studies published in English were considered for inclusion in this review. Qualitative papers selected for retrieval were assessed using the standardized critical appraisal instrument from the Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI). Data were extracted from the seven included papers using the standardized data extraction tool from JBI-QARI. The data were synthesized using the JBI approach to meta-synthesis by meta-aggregation using the JBI-QARI software and methods. Seven studies of moderate quality were included in the review. Forty findings were extracted and aggregated to create 10 categories, from which five synthesized findings were derived: CONCLUSION: In contrast to "lay" FMs, health professionals possess additional knowledge and understanding that alter their perceptions and expectations, and the expectations others have of them. This knowledge and understanding can be an advantage in navigating a complex health system but may also result in an additional burden such as role conflict.

2012-09-01

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

Clear: Composition of Likelihoods for Evolve and Resequence Experiments.

Iranmehr, Arya; Akbari, Ali; Schlötterer, Christian; Bafna, Vineet

2017-06-01

The advent of next generation sequencing technologies has made whole-genome and whole-population sampling possible, even for eukaryotes with large genomes. With this development, experimental evolution studies can be designed to observe molecular evolution "in action" via evolve-and-resequence (E&R) experiments. Among other applications, E&R studies can be used to locate the genes and variants responsible for genetic adaptation. Most existing literature on time-series data analysis often assumes large population size, accurate allele frequency estimates, or wide time spans. These assumptions do not hold in many E&R studies. In this article, we propose a method-composition of likelihoods for evolve-and-resequence experiments (Clear)-to identify signatures of selection in small population E&R experiments. Clear takes whole-genome sequences of pools of individuals as input, and properly addresses heterogeneous ascertainment bias resulting from uneven coverage. Clear also provides unbiased estimates of model parameters, including population size, selection strength, and dominance, while being computationally efficient. Extensive simulations show that Clear achieves higher power in detecting and localizing selection over a wide range of parameters, and is robust to variation of coverage. We applied the Clear statistic to multiple E&R experiments, including data from a study of adaptation of Drosophila melanogaster to alternating temperatures and a study of outcrossing yeast populations, and identified multiple regions under selection with genome-wide significance.

Cancer is associated with disease-related and treatment-related symptoms. Little is known about the symptom experience of black individuals with advanced cancer especially those with limited financial resources. Therefore, the purpose of this study was to explore the symptom experience of black adults with advanced cancer living in poverty. This qualitative descriptive study focused on the perspectives of the participants experiencing at least two symptoms related to cancer. A purposive sample of 27 individuals receiving care at a public hospital in a southeastern city participated in the study. Semi-structured audiotaped interviews were conducted by two research interviewers. Content analysis was used to develop themes to describe the symptom experience. Two main themes emerged in terms of the participants' symptom experiences: (1) "living in pain," which included the overwhelming experience of pain, both physical and emotional, and (2) "symptoms associated with functioning in everyday life." Participants frequently used the context of activities in their daily lives to explain symptoms, including the effect of symptoms on the activities of eating, moving and doing, and communicating. People with advanced cancer work to negotiate a high frequency of multiple distressful symptoms of severe-to-moderate severity. Information gained from this study can help guide research in symptom science and provide direction for clinicians working with this minority group.

Use of animal models for space flight physiology studies, with special focus on the immune system

NASA Technical Reports Server (NTRS)

Sonnenfeld, Gerald

2005-01-01

Animal models have been used to study the effects of space flight on physiological systems. The animal models have been used because of the limited availability of human subjects for studies to be carried out in space as well as because of the need to carry out experiments requiring samples and experimental conditions that cannot be performed using humans. Experiments have been carried out in space using a variety of species, and included developmental biology studies. These species included rats, mice, non-human primates, fish, invertebrates, amphibians and insects. The species were chosen because they best fit the experimental conditions required for the experiments. Experiments with animals have also been carried out utilizing ground-based models that simulate some of the effects of exposure to space flight conditions. Most of the animal studies have generated results that parallel the effects of space flight on human physiological systems. Systems studied have included the neurovestibular system, the musculoskeletal system, the immune system, the neurological system, the hematological system, and the cardiovascular system. Hindlimb unloading, a ground-based model of some of the effects of space flight on the immune system, has been used to study the effects of space flight conditions on physiological parameters. For the immune system, exposure to hindlimb unloading has been shown to results in alterations of the immune system similar to those observed after space flight. This has permitted the development of experiments that demonstrated compromised resistance to infection in rodents maintained in the hindlimb unloading model as well as the beginning of studies to develop countermeasures to ameliorate or prevent such occurrences. Although there are limitations to the use of animal models for the effects of space flight on physiological systems, the animal models should prove very valuable in designing countermeasures for exploration class missions of the future.

2017-01-01

Objectives We aimed to explore healthcare professionals’ experience of treating chronic non-malignant pain by conducting a qualitative evidence synthesis. Understanding this experience from the perspective of healthcare professionals will contribute to improvements in the provision of care. Design Qualitative evidence synthesis using meta-ethnography. We searched five electronic bibliographic databases from inception to November 2016. We included studies that explore healthcare professionals’ experience of treating adults with chronic non-malignant pain. We used the GRADE-CERQual framework to rate confidence in review findings. Results We screened the 954 abstracts and 184 full texts and included 77 published studies reporting the experiences of over 1551 international healthcare professionals including doctors, nurses and other health professionals. We abstracted six themes: (1) a sceptical cultural lens, (2) navigating juxtaposed models of medicine, (3) navigating the geography between patient and clinician, (4) challenge of dual advocacy, (5) personal costs and (6) the craft of pain management. We rated confidence in review findings as moderate to high. Conclusions This is the first qualitative evidence synthesis of healthcare professionals’ experiences of treating people with chronic non-malignant pain. We have presented a model that we developed to help healthcare professionals to understand, think about and modify their experiences of treating patients with chronic pain. Our findings highlight scepticism about chronic pain that might explain why patients feel they are not believed. Findings also indicate a dualism in the biopsychosocial model and the complexity of navigating therapeutic relationships. Our model may be transferable to other patient groups or situations.

Beginning with OSTA-1 in November 1981, and ending with Neurolab n March 1998, thirty-six shuttle missions are considered Spacelab missions because they carried various Spacelab components such as the Spacelab module, the pallet, the Instrument Pointing System (IPS), or the MPESS (Mission Peculiar Experiment Support Structure). The experiments carried out during these flights included astrophysics, solar physics, plasma physics, atmospheric science, Earth observations, and a wide range of microgravity experiments in life sciences, biotechnology, materials science, and fluid physics which includes combustion and critical point phenomena. In all, some 764 experiments were conducted by investigators from the United States, Europe, and Japan. These experiments resulted in several thousand papers published in refereed journals, and thousands more in conference proceedings, chapters in books, and other publications. The purpose of this Spacelab Science Results Study is to document the contributions made in each of the major research areas by giving a brief synopsis of the more significant experiments and an extensive list of the publications that were produced. We have also endeavored to show how these results impacted the existing body of knowledge, where they have spawned new fields, and, if appropriate, where the knowledge they produced has been applied.

Why Older Adults May Decline Offers of Post-Acute Care Services: A Qualitative Descriptive Study

2016-01-01

The most common post-acute care (PAC) services available to patients after hospital discharge include home care, skilled nursing facilities, nursing homes, inpatient rehabilitation, and hospice. Patients who need PAC and receive services have better outcomes, however almost one-third of those offered services decline. Little research exists on PAC decision-making and why patients may decline services. This qualitative descriptive study explored the responses of thirty older adults to the question: “Can you, from the patient point of view, tell me why someone would not want post hospital care?” Three themes emerged. Participants may decline due to 1) previous negative experiences with PAC, or 2) a preference to be home. Some participants stated, “I'd be there” and would not decline services. Participants also discussed 3) why other patients might decline PAC which included patients’ past experiences, fear of the unknown, and preferences. Clinical implications include assessing patients’ knowledge and experience before providing recommendations. PMID:27964972

2008-03-01

The aim of this article is to review the scientific literature on making sense of war and peacekeeping experiences, and it includes an analysis of empirical studies that examine appraisals of military deployment experiences among veterans. Veterans reported more positive than negative effects in the studies of this review. Furthermore, construing positive meaning from war and peacekeeping experiences, especially related to combat exposure or high perceived threat, is associated with better psychological adjustment. More insight on "normal" psychological processing of stressful and traumatic experiences is obtained when the concept of meaning is used in research. This perspective emphasizes the perception of individuals and focuses on beliefs and attitudes in making sense of threatening events instead of pathologizing the response to trauma.

Background: Lesbian, gay, bisexual and/or trans (LGBT) people have higher risk of certain life-limiting illnesses and unmet needs in advanced illness and bereavement. ACCESSCare is the first national study to examine in depth the experiences of LGBT people facing advanced illness. Aim: To explore health-care experiences of LGBT people facing advanced illness to elicit views regarding sharing identity (sexual orientation/gender history), accessing services, discrimination/exclusion and best-practice examples. Design: Semi-structured in-depth qualitative interviews analysed using thematic analysis. Setting/participants: In total, 40 LGBT people from across the United Kingdom facing advanced illness: cancer (n = 21), non-cancer (n = 16) and both a cancer and a non-cancer conditions (n = 3). Results: In total, five main themes emerged: (1) person-centred care needs that may require additional/different consideration for LGBT people (including different social support structures and additional legal concerns), (2) service level or interactional (created in the consultation) barriers/stressors (including heteronormative assumptions and homophobic/transphobic behaviours), (3) invisible barriers/stressors (including the historical context of pathology/criminalisation, fears and experiences of discrimination) and (4) service level or interactional facilitators (including acknowledging and including partners in critical discussions). These all shape (5) individuals’ preferences for disclosing identity. Prior experiences of discrimination or violence, in response to disclosure, were carried into future care interactions and heightened with the frailty of advanced illness. Conclusion: Despite recent legislative change, experiences of discrimination and exclusion in health care persist for LGBT people. Ten recommendations, for health-care professionals and services/institutions, are made from the data. These are simple, low cost and offer potential gains in access to, and outcomes of, care for LGBT people. PMID:28502218

Natuculture Systems: Addressing Students' STEM and Agriculture Knowledge

NASA Astrophysics Data System (ADS)

Joyce, Alexander Augusto

The purpose of this study was to assess the inclusion of a Natuculture systems learning experience into selected high school STEM courses to determine high school students' interests in majoring in STEM and for pursuing careers in agricultural sciences. Natuculture is defined as "any human-made system that mimics nature in human-disturbed landscapes". The research occurred at an urban area high school located in the Piedmont region of North Carolina. Fifty-three students in grades 9-12 participated during an academic semester learning experience which included planting, maintenance, & harvesting for an oasissofa. Data was collected using a questionnaire and reflective journals to gather students' attitudes towards agriculture and science and knowledge towards agriculture. Results showed that while the experiences did not improve students' interest in pursuing careers in agricultural sciences, overall, they did increase their knowledge of concepts related to agriculture. It was concluded that students benefit from experiential learning experiences. Based on the study, it is recommended that future research follow up with students to learn of their educational and career choices in agriculture and future learning experiences include curricula that integrates agricultural topics with STEM courses.

2002-01-01

In order to support humans for long-duration missions to Mars, bioregenerative Advanced Life Support (ALS) systems have been proposed that would use higher plants as the primary candidates for photosynthesis. Hydroponic technologies have been suggested as the primary method of plant production in ALS systems, but the use of Mars regolith as a plant growth medium may have several advantages over hydroponic systems. The advantages for using Mars regolith include the likely bioavailability of plant-essential ions, mechanical support for plants, and easy access of the material once on the surface. We propose that plant biology experiments must be included in near-term Mars lander missions in order to begin defining the optimum approach for growing plants on Mars. Second, we discuss a range of soil chemistry and soil physics tests that must be conducted prior to, or in concert with, a plant biology experiment in order to properly interpret the results of plant growth studies in Mars regolith. The recommended chemical tests include measurements on soil pH, electrical conductivity and soluble salts, redox potential, bioavailability of essential plant nutrients, and bioavailability of phytotoxic elements. In addition, a future plant growth experiment should include procedures for determining the buffering and leaching requirements of Mars regolith prior to planting. Soil physical tests useful for plant biology studies in Mars regolith include bulk density, particle size distribution, porosity, water retention, and hydraulic conductivity.

Animal experiments remain essential to understand the fundamental mechanisms underpinning malignancy and to discover improved methods to prevent, diagnose and treat cancer. Excellent standards of animal care are fully consistent with the conduct of high quality cancer research. Here we provide updated guidelines on the welfare and use of animals in cancer research. All experiments should incorporate the 3Rs: replacement, reduction and refinement. Focusing on animal welfare, we present recommendations on all aspects of cancer research, including: study design, statistics and pilot studies; choice of tumour models (e.g., genetically engineered, orthotopic and metastatic); therapy (including drugs and radiation); imaging (covering techniques, anaesthesia and restraint); humane endpoints (including tumour burden and site); and publication of best practice.

The experience of art offers an emerging field in healthcare staff development, much of which is appropriate to the practice of palliative care. The workings of aesthetic learning interventions such as interactive theatre in relation to palliative and end-of-life care staff development programmes are widely uncharted. To investigate the use of aesthetic learning interventions used in palliative and end-of-life care staff development programmes. Scoping review. Published literature from 1997 to 2015, MEDLINE, CINAHL and Applied Social Sciences Index and Abstracts, key journals and citation tracking. The review included 138 studies containing 60 types of art. Studies explored palliative care scenarios from a safe distance. Learning from art as experience involved the amalgamation of action, emotion and meaning. Art forms were used to transport healthcare professionals into an aesthetic learning experience that could be reflected in the lived experience of healthcare practice. The proposed learning included the development of practical and technical skills; empathy and compassion; awareness of self; awareness of others and the wider narrative of illness; and personal development. Aesthetic learning interventions might be helpful in the delivery of palliative care staff development programmes by offering another dimension to the learning experience. As researchers continue to find solutions to understanding the efficacy of such interventions, we argue that evaluating the contextual factors, including the interplay between the experience of the programme and its impact on the healthcare professional, will help identify how the programmes work and thus how they can contribute to improvements in palliative care.

Ethics and quality care in nursing homes: Relatives' experiences.

2017-01-01

A total of 71,000 people in Norway suffer from some form of dementia in 2013, of whom approximately 30,000 are in nursing homes. Several studies focus on the experiences of those who have close relatives and who are staying in a nursing home. Results show that a greater focus on cooperation between nursing staff and relatives is a central prerequisite for an increased level of care. Benefits of developing systematic collaboration practices include relief for nursing staff, less stress, and greater mutual understanding. Going through studies focusing on the experiences of nursing home patients' relatives, negative experiences are in the majority. In this study, relatives are invited to share positive experiences regarding the care of their loved ones; a slightly different perspective, in other words. The aim of the study is to investigate relatives of persons with dementia's experiences with quality care in nursing homes. The study is a part of a larger project called Hospice values in the care for persons with dementia and is based on a qualitative design where data are generated through narrative interviews. The chosen method of analysis is the phenomenological-hermeneutical method for the study of lived experiences. Participants and research context: Participants in the project were eight relatives of persons with dementia who were living in nursing homes, long-term residences. The sampling was targeted, enrolment happened through collective invitation. All relatives interested were included. Ethical considerations: The Norwegian Regional Ethics Committee and the Norwegian Social Science Data Services approve the study. Findings show that relatives have certain expectations as to how their loved ones ought to be met and looked after at the nursing home. The results show that in those cases where the expectations were met, the relatives' experiences were associated with engagement, inclusion and a good atmosphere. When the expectations were not met, the relatives experienced powerlessness, distrust and guilt. The results are discussed considering the concepts of trust, power and asymmetry. When asked about experiences with quality care, the relatives spoke both of expectations met and of expectations not met. Results in this study are important knowledge for developing units where performing quality care is the overall aim.

Face-to-face instruction, paper-based case-studies and clinical placements remain the most commonly used teaching methods for therapeutics curricula. Presenting clinical content in a didactic manner presents challenges in engaging learners and developing their clinical reasoning skills which may be overcome by inclusion of the virtual patient (VP). Currently there is limited literature examining the use of the VP in therapeutics teaching and learning. This review aimed to determine the role of VPs in therapeutics education, specifically the impact on student experiences, performance, and clinical skills. A search of primary literature was conducted with search terms including virtual patient, education, health, AND learning. Boolean operators were applied to include studies from health relevant fields with article titles and abstracts vetted. Nine of the 21 included studies were control-matched, and all but one compared VPs to traditional teaching. VPs enhanced the learning experience in all 17 studies that measured this outcome. Fourteen studies measured performance and clinical skills and 12 found VPs were beneficial, while two did not. The VP was not superior to traditional teaching in all studies, but the VP appeared beneficial to the student learning experience. Discrepancy was found between the impact of VPs on short- and long-term knowledge. The VP appears to enhance the student learning experience and has a role in therapeutics education, however a blended-learning (BL) approach may be required to account for individual learning styles. Additional investigation is required to clarify the efficacy of the VP, particularly as a component of BL, on longer-term knowledge retention. Copyright © 2017 Elsevier Inc. All rights reserved.

Health care professionals have advocated for educating culturally competent practitioners. Immersion in international experiences has an impact on student cultural competency and interprofessional development. The China Honors Interprofessional Program (CHIP) at a university in the Midwest is designed to increase students' cultural competency and interprofessional development. From 2009 to 2013, a total of 25 professional students including twelve occupational therapy students, ten physical therapy students and three nursing students were enrolled in the programme. Using a one group pre and posttest research design, this study evaluated the impact of CHIP on the participating students. Both quantitative and qualitative data were collected in the study. Findings of the study revealed that CHIP has impact on students' cultural competency and professional development including gaining appreciation and understanding of the contributions of other healthcare professionals and knowledge and skills in team work. The findings of the study suggested that international immersion experience such as CHIP is an important way to increase students' cultural competency and interprofessional knowledge and skills. Limitations of the study included the small sample in the study, indirect outcome measures and the possible celling effect of the instruments of the study. Future research studies should include a larger and more representative sample, direct outcome measures such as behaviour observation and more rigorous design such as prospective experimental comparison group design. Future research should also examine the long-term effects of international experience on the professional development of occupational therapy students. Copyright © 2016 John Wiley & Sons, Ltd.

2017-06-02

Few studies have explored patients' experiences of treatment for CFS/ME. This study aims to fill this gap by capturing the perspective of patients who have been treated by NHS specialist CFS/ME services in England. Semi-structured interviews were conducted during the period June-September 2014 with 16 adults who were completing treatment at one of three outpatient NHS specialist CFS/ME services. Interviews were analysed thematically using constant comparison techniques, with particular attention paid to contrasting views. Three themes were identified: 'Journey to specialist services'; 'Things that help or hinder treatment'; and 'Support systems'. Within these themes nine sub-themes were identified. A wide range of factors was evident in forming participants' experiences, including personal characteristics such as perseverance and optimism, and service factors such as flexibility and positive, supportive relationships with clinicians. Participants described how specialist services played a unique role, which was related to the contested nature of the condition. Many participants had experienced a lack of validation and medical and social support before attending a specialist service. Patients' experiences of life before referral, and the concerns that they expressed about being discharged, highlighted the hardship and obstacles which people living with CFS/ME continue to experience in our society. The experiences of CFS/ME patients in our study showed that NHS specialist CFS/ME services played a vital role in patients' journeys towards an improved quality of life. This improvement came about through a process which included validation of patients' experiences, acceptance of change, practical advice and support, and therapeutic outcomes.

The many faces of amnesia.

PubMed

Gold, Paul E

2006-01-01

Results from studies of retrograde amnesia provide much of the evidence for theories of memory consolidation. Retrograde amnesia gradients are often interpreted as revealing the time needed for the formation of long-term memories. The rapid forgetting observed after many amnestic treatments, including protein synthesis inhibitors, and the parallel decay seen in long-term potentiation experiments are presumed to reveal the duration of short-term memory processing. However, there is clear and consistent evidence that the time courses obtained in these amnesia experiments are highly variable within and across experiments and treatments. The evidence is inconsistent with identification of basic temporal properties of memory consolidation. Alternative views include modulation of memory and emphasize the roles that hormones and neurotransmitters have in regulating memory formation. Of related interest, converging lines of evidence suggest that inhibitors of protein synthesis and of other biochemical processes act on modulators of memory formation rather than on mechanisms of memory formation. Based on these findings, memory consolidation and reconsolidation studies might better be identified as memory modulation and "remodulation" studies. Beyond a missing and perhaps unattainable time constant of memory consolidation, some current views of memory consolidation assume that memories, once formed, are generally unmodifiable. It is this perspective that appears to have led to the recent interest in memory reconsolidation. But the view adopted here is that memories are continually malleable, being updated by new experiences and, at the same time, altering the memories of later experiences. Studies of memory remodulation offer promise of understanding the neurobiological bases by which new memories are altered by prior experiences and by which old memories are altered by new experiences.

The Potential to use Publication of Undergraduate Research as a Teaching Tool

NASA Astrophysics Data System (ADS)

Brevik, Eric C.; Lindbo, David L.; Belcher, Christopher

2015-04-01

Several studies crossing numerous disciplinary boundaries have demonstrated that undergraduate students benefit from research experiences. These benefits include personal and intellectual development, more and closer contact with faculty, the use of active learning techniques, the creation of high expectations, the development of creative and problem-solving skills, and the development of greater independence and intrinsic motivation to learn. The discipline also gains in that studies show undergraduates who engage in research experiences are more likely to remain science majors and finish their degree program. Research experiences come as close as possible to allowing undergraduates to experience what it is like to be an academic or research member of their profession working to advance their discipline, therefore enhancing their professional socialization into their chosen field. If the goals achieved by undergraduate research include introducing these students to the advancement of their chosen field, it stands to reason the ultimate ending to this experience would be the publication of a peer-reviewed paper. While not all undergraduate projects will end with a product worthy of peer-reviewed publication, some definitely do, and the personal experience of the authors indicates that undergraduate students who achieve publication get great satisfaction and a sense of personal achievement from that publication. While a top-tier international journal probably isn't going to be the ultimate destination for many of these projects, there are several appropriate outlets. The SSSA journal Soil Horizons has published several undergraduate projects in recent years, and good undergraduate projects can often be published in state academy of science journals. Journals focused expressly on publishing undergraduate research include the Journal of Undergraduate Research and Scholarly Excellence, Reinvention, and the American Journal of Undergraduate Research. Case studies of students who have published undergraduate research will be discussed.

Parental, child, and adolescent experience of chronic skin conditions: A meta-ethnography and review of the qualitative literature.

PubMed

Ablett, Kate; Thompson, Andrew R

2016-12-01

Childhood skin conditions can affect the quality of life of children, adolescents, and families. As such, paediatric dermatological conditions have been the focus of a number of qualitative studies and there is now a need to integrate the findings. A meta-ethnography was carried out with the existing 12 studies, which included nine studies examining parental experiences and three studies of child experiences. Meta-ethnographic analysis of the studies identified themes focused on the child's sense of stigmatisation and the challenges for families that arose from this. Common experiences across studies were feelings of difference relating to the appearance of the skin. The results highlight that children and adolescents can experience negative social reactions and that parents may struggle with some aspects of the physical management of the condition. The studies indicate the need to examine in more detail the psychosocial aspects of childhood skin conditions and the role played by stigmatisation. Copyright © 2016 Elsevier Ltd.

Vaginal birth after Caesarean section (VBAC) is a relevant question for a large number of women due to the internationally rising Caesarean section (CS) rate. There is a great deal of research based on quantitative studies but few qualitative studies about women's experiences. A metasynthesis based on the interpretative meta ethnography method was conducted. The inclusion criterion was peer-review qualitative articles from different disciplines about women's experiences of VBAC. Eleven articles were checked for quality, and eight articles were included in the synthesis. The included studies were from Australia (four), UK (three), and US (one), and studied women's experience in relation to different aspects of VBAC; decision-making whether to give birth vaginally, the influence of health professionals on decision-making, reason for trying a vaginal birth, experiences when choosing VBAC, experiences of giving birth vaginally, and giving birth with CS when preferring VBAC. The main results are presented with the metaphor groping through the fog; for the women the issue of VBAC is like being in a fog, where decision-making and information from the health care system and professionals, both during pregnancy and the birth, is unclear and contrasting. The results are further presented with four themes: 'to be involved in decision about mode of delivery is difficult but important,' 'vaginal birth has several positive aspects mainly described by women,' 'vaginal birth after CS is a risky project,' and 'own strong responsibility for giving birth vaginally'. In order to promote VBAC, more studies are needed from different maternity settings and countries about women's experiences. Women need evidence-based information not only about the risks involved but also positive aspects of VBAC.

Former inmates are at high risk for death from drug overdose, especially in the immediate post-release period. The purpose of the study is to understand the drug use experiences, perceptions of overdose risk, and experiences with overdose among former prisoners. This qualitative study included former prison inmates (N=29) who were recruited within two months after their release. Interviewers conducted in-person, semi-structured interviews which explored participants' experiences and perceptions. Transcripts were analyzed utilizing a team-based method of inductive analysis. The following themes emerged: 1) Relapse to drugs and alcohol occurred in a context of poor social support, medical co-morbidity and inadequate economic resources; 2) former inmates experienced ubiquitous exposure to drugs in their living environments; 3) intentional overdose was considered "a way out" given situational stressors, and accidental overdose was perceived as related to decreased tolerance; and 4) protective factors included structured drug treatment programs, spirituality/religion, community-based resources (including self-help groups), and family. Former inmates return to environments that strongly trigger relapse to drug use and put them at risk for overdose. Interventions to prevent overdose after release from prison may benefit from including structured treatment with gradual transition to the community, enhanced protective factors, and reductions of environmental triggers to use drugs.

Padmanabhanunni, Anita; Jaffer, Labeeqah; Steenkamp, Jeanette

2017-09-15

A growing body of research has emphasised the salience of cultural beliefs and traditional practices to women's experiences of menstruation. Relatively less research has, however, been undertaken in South Africa. This study explored the experience of menstruation among women from the ama-Xhosa ethnic group, one of the largest ethnic groups in the country. Among the ama-Xhosa, there are distinct cultural practices associated with menstruation, including the female rite of passage (intonjane) and virginity testing (inkciyo). However, few studies have explored the experience of menstruation for women from this cultural group. This study involved the synthesis of data from individual interviews and focus group discussions conducted among a sample of ama-Xhosa women. The data were analysed using thematic analysis. Distinctive findings included women's participation in traditional cultural practices of intonjane and inkciyo and the presence of cultural taboos associated with menstruation. Women's narratives revealed strong ambivalence regarding these practices. On the one hand, they wanted to adhere to traditional practices but experienced these customs as evoking discomfort and shame. The study confirmed the prevalence of negative constructions of menstruation. Positive appraisals of menstruation as evoking joy and happiness were also encountered.

Following the Long Duration Exposure Facility (LDEF) retrieval, the Systems Special Investigation Group (SIG) participated in an extensive series of tests of various electronic systems, including the NASA provided data and initiate systems, and some experiment systems. Overall, these were found to have performed remarkably well, even though most were designed and tested under limited budgets and used at least some nonspace qualified components. However, several anomalies were observed, including a few which resulted in some loss of data. The postflight test program objectives, observations, and lessons learned from these examinations are discussed. All analyses are not yet complete, but observations to date will be summarized, including the Boeing experiment component studies and failure analysis results related to the Interstellar Gas Experiment. Based upon these observations, suggestions for avoiding similar problems on future programs are presented.

Race differences in the relationship between role experiences and well-being.

PubMed

Marcussen, Kristen; Piatt, Liz

2005-07-01

Theory and research generally support the notion that social roles benefit subjective well-being. These conclusions, however, are largely based on studies examining Whites. Studies that have included Blacks have found race differences in the influence of social roles on well-being, yet most of these studies focus on role occupancy. With few exceptions, little attention has been paid to whether there are race differences in how individuals experience their roles, and the extent to which race differences in role experiences relate to differences in well-being. In this article we examine racial variation in the experience of work and family roles. We find that Blacks and Whites are similar in their experiences of role conflict and perceptions of role success and balance, but the association between these experiences and well-being varies, to some extent, by race and gender. The implications of these findings as well as suggestions for future research are discussed.

Older adult's experience of chronic low back pain and its implications on their daily life: Study protocol of a systematic review of qualitative research.

2018-05-24

Of various chronic diseases, low back pain (LBP) is the most common and debilitating musculoskeletal condition among older adults aged 65 years or older. While more than 17 million older adults in the USA suffer from at least one episode of LBP annually, approximately six million of them experience chronic LBP that significantly affects their quality of life and physical function. Since many older adults with chronic LBP may also have comorbidities and are more sensitive to pain than younger counterparts, these older individuals may face unique age-related physical and psychosocial problems. While some qualitative research studies have investigated the life experiences of older adults with chronic LBP, no systematic review has integrated and synthesized the scientific knowledge regarding the influence of chronic LBP on the physical, psychological, and social aspects of lives in older adults. Without such information, it may result in unmet care needs and ineffective interventions for this vulnerable group. Therefore, the objective of this systematic review is to synthesize knowledge regarding older adults' experiences of living with chronic LBP and the implications on their daily lives. Candidate publications will be sought from databases: PubMed, CINAHL, and PsycINFO. Qualitative research studies will be included if they are related to the experiences of older adults with chronic LBP. Two independent reviewers will screen the titles, abstracts, and full-text articles for eligibility. The reference lists of the included studies will be checked for additional relevant studies. Forward citation tracking will be conducted. Meta-ethnography will be chosen to synthesize the data from the included studies. Specifically, the second-order concepts that are deemed to be translatable by two independent reviewers will be included and synthesized to capture the core of the idiomatic translations (i.e., a translation focusing on salient categories of meaning rather than the literal translation of words or phrases). This systematic review of qualitative evidence will enable researchers to identify potential unmet care needs, as well as to facilitate the development of effective, appropriate, person-centered health care interventions targeting this group of individuals.

Study preferences for exemplar variability in self-regulated category learning.

PubMed

Wahlheim, Christopher N; DeSoto, K Andrew

2017-02-01

Increasing exemplar variability during category learning can enhance classification of novel exemplars from studied categories. Four experiments examined whether participants preferred variability when making study choices with the goal of later classifying novel exemplars. In Experiments 1-3, participants were familiarised with exemplars of birds from multiple categories prior to making category-level assessments of learning and subsequent choices about whether to receive more variability or repetitions of exemplars during study. After study, participants classified novel exemplars from studied categories. The majority of participants showed a consistent preference for variability in their study, but choices were not related to category-level assessments of learning. Experiment 4 provided evidence that study preferences were based primarily on theoretical beliefs in that most participants indicated a preference for variability on questionnaires that did not include prior experience with exemplars. Potential directions for theoretical development and applications to education are discussed.

Menstruation across time: menarche, menstrual attitudes, experiences, and behaviors.

PubMed

McPherson, Marianne E; Korfine, Lauren

2004-01-01

This study explored the relationship between early and current menstrual experiences. The primary hypothesis was that women who reported positive menarcheal experiences (including menstrual education and menarche) would tend to report positive current menstrual attitudes, experiences, and/or behaviors, and vice versa for women who reported negative menarcheal experiences. In this survey-based study, college-aged women (n = 327) were screened by completing a questionnaire concerning their menarcheal experiences. Women who had extremely negative ("negative group," n = 46) or extremely positive ("positive group," n = 38) early menstrual experiences returned to complete questionnaires concerning current menstrual attitudes, experiences, and behaviors. Early and current menstrual experiences were most strongly associated in the domain of menstrual attitudes. Women in the negative group reported more negative menstrual attitudes than did women in the positive group. There were additional associations between early menstrual experiences and measures of body image and health behaviors. Positive group participants reported more positive body image and better general health behaviors. Results suggest that early menstrual experiences may be related to menstrual experiences later in life. This study invites further investigation of the psychology of menstruation and suggests connecting menstruation with other women's health issues.

This study explored patient experiences in home health care through a literature review, focus groups, and interviews. Our goal was to develop a conceptual map of home health care patient experience domains. The conceptual map identifies technical and personal spheres of care, relating prior studies to new focus group and interview findings and identifying the most important domains of care. Study participants (n = 35) most frequently reported the most important domain as staff who are caring, supportive, patient, empathetic, respectful, and considerate (endorsed by 29% of participants). The conceptual map includes 114 discrete domains.

Microplate-Based Method for High-Throughput Screening (HTS) of Chromatographic Conditions Studies for Recombinant Protein Purification.

PubMed

Carvalho, Rimenys J; Cruz, Thayana A

2018-01-01

High-throughput screening (HTS) systems have emerged as important tools to provide fast and low cost evaluation of several conditions at once since it requires small quantities of material and sample volumes. These characteristics are extremely valuable for experiments with large number of variables enabling the application of design of experiments (DoE) strategies or simple experimental planning approaches. Once, the capacity of HTS systems to mimic chromatographic purification steps was established, several studies were performed successfully including scale down purification. Here, we propose a method for studying different purification conditions that can be used for any recombinant protein, including complex and glycosylated proteins, using low binding filter microplates.

A Phenomenological Research Study of the Experience of Teachers in the Virgin Islands Teacher Enhancement in Mathematics and Science Project

NASA Astrophysics Data System (ADS)

Thurland, Karen C.

The purpose of conducting this study was to describe the experience of elementary teachers in a mathematics and science staff development project in the U.S. Virgin Islands. The focus of this study was to describe the meaning teachers attribute to their experience in this three year project, in which many of the national mathematics and science reform efforts were implemented. A phenomenological approach was used in order to develop a complete picture of the teachers' experiences. Data collection consisted of interviews with seven elementary teachers. The data were subjective descriptions of the teachers pertaining to the initial summer institute, the follow-up sessions, and the new innovative methods. The transcendental phenomenological model was used. The textural and structural themes included enhanced learning and changes in teaching practice, and interactions with colleagues. From these themes, individual and composite textual descriptions of the experience of the teacher participants were developed. The synthesis of those descriptions illuminated the meanings and essence of their lived experience. The findings indicate that the essence of the experience was the development of a positive attitude towards the teaching of math and science. The teachers gained confidence in their ability to motivate students with the inquiry method and taught more math and science. The implications for the Virgin Islands Department of Education include establishing a partnership with the local university to offer staff development training in mathematics and science and to conduct evaluations of its training efforts.

The impact of international experience on student nurses' personal and professional development.

PubMed

Lee, N-J

2004-06-01

Many student nurses undertake international clinical experience during their education programmes, which raises the question 'How do these experiences impact on students nurses' personal and professional development?' A case study was conducted in one School of Nursing in the United Kingdom. Student nurses participating in a new module, International Nursing and Health Care, which included clinical experience overseas, gave qualitative accounts of their international experiences and subsequent learning. Their accounts were also compared with the perceptions and expectations of the module facilitators. While there were some similarities in student experience and facilitator expectations, there were also notable differences. The students believed that their international experiences had a deep impact on their personal development, helping them make the transition from student to qualified nurse. The case study raised further questions about the acquisition of cultural knowledge and the facilitation and provision of learning from experience.

Libet’s clock is a well-known procedure in experiments in psychology and neuroscience. Examples of its use include experiments exploring the subjective sense of agency, action-effect binding, and subjective timing of conscious decisions and perceptions. However, the technical details of the apparatus used to conduct these types of experiments are complex, and are rarely explained in sufficient detail as to guarantee an exact replication of the procedure. With this in mind, we developed Labclock Web, a web tool designed to conduct online and offline experiments using Libet’s clock. After describing its technical features, we explain how to configure specific experiments using this tool. Its degree of accuracy and precision in the presentation of stimuli has been technically validated, including the use of two cognitive experiments conducted with voluntary participants who performed the experiment both in our laboratory and via the Internet. Labclock Web is distributed without charge under a free software license (GPLv3) since one of our main objectives is to facilitate the replication of experiments and hence the advancement of knowledge in this area.

2016-01-01

This study examines the emotional experiences and perceptions of librarians embedded into clinical care teams and how those perceptions affect their training and preparation needs. Qualitative research methodologies were applied to textual data drawn from focus groups (n=21), interviews (n=2), and an online survey (n=167), supplemented by quantitative survey data. Phenomenological results show librarians experience strongly effective responses to clinical rounding. Important factors include personal confidence; relationships with team members, patients, and families; and the stressful environment. Analysis of librarians’ perceived educational needs indicates that training must address specialized subjects including medical knowledge, clinical culture, and institutional politics. PMID:26211792

1989-01-01

Risk methodology is used to define experiments to be conducted in space which will help to construct and test the models required for accident sequence identification. The development of accident scenarios is based on the realization that whether damage occurs depends on the time competition of two processes: the ignition and creation of an adverse environment, and the detection and suppression activities. If the fire grows and causes damage faster than it is detected and suppressed, then an accident occurred. The proposed integrated experiments will provide information on individual models that apply to each of the above processes, as well as previously unidentified interactions and processes, if any. Initially, models that are used in terrestrial fire risk assessments are considered. These include heat and smoke release models, detection and suppression models, as well as damage models. In cases where the absence of gravity substantially invalidates a model, alternate models will be developed. Models that depend on buoyancy effects, such as the multizone compartment fire models, are included in these cases. The experiments will be performed in a variety of geometries simulating habitable areas, racks, and other spaces. These simulations will necessitate theoretical studies of scaling effects. Sensitivity studies will also be carried out including the effects of varying oxygen concentrations, pressures, fuel orientation and geometry, and air flow rates. The experimental apparatus described herein includes three major modules: the combustion, the fluids, and the command and power modules.

Unusual Sleep Experiences, Dissociation, and Schizotypy: Evidence for a Common Domain

PubMed Central

Koffel, Erin; Watson, David

2009-01-01

This paper reviews studies that have examined associations between unusual sleep experiences (including nightmares, vivid dreaming, narcolepsy symptoms, and complex nighttime behaviors) and dissociation and schizotypy. Using correlational studies and structural analyses, evidence is provided that unusual sleep experiences, dissociation, and schizotypy belong to a common domain. It is demonstrated that unusual sleep experiences show specificity to dissociation and schizotypy compared to other daytime symptoms (e.g., anxiety, depression, substance use) and other sleep disturbances (e.g., insomnia, lassitude/fatigue). The paper also outlines the methodological limitations of the existing evidence and makes suggestions for future research. Finally, three models for the overlap of daytime and nighttime symptoms are reviewed, including biological abnormalities, trauma, and personality traits. Although further research is needed, it is suggested that daytime and nighttime symptoms result from problems with sleep-wake state boundaries, which may be precipitated by stress or trauma. In addition, association between daytime and nighttime symptoms can be attributed to the higher order personality trait of Oddity. PMID:19581031

Understanding Graduate Teaching Assistants as Tutorial Instructors

Scherr, Rachel E.; Elby, A.

2006-12-01

Physics graduate teaching assistants are essential to the implementation of many collaborative active-learning environments, including tutorials. However, many TAs have trouble teaching effectively in these formats. Anecdotal evidence suggests that the problems may include inappropriate models of physics students, unproductive theories of learning, lack of experience with modern pedagogical methods, and weaknesses in understanding basic physics topics. A new research project at the University of Maryland is investigating the specific nature of TAs' experience with reform instruction using in-depth studies of TAs in course preparation sessions, in the tutorial classroom, in a weekly teaching seminar, and in reflective interviews. We find that all TAs studied recognize the insufficiency of traditional instruction to at least some extent, citing as evidence their own learning experiences, prior teaching experiences, and exposure to FCI-type data. We also observe great variability in views of the nature of physics knowledge and learning (both professed and enacted). These results are informing the development of the professional development program for physics teaching assistants at the University of Maryland.

War-traumatized refugee children and adolescents have been overlooked in research on trauma-related dissociation, and whatever research has been conducted has relied almost exclusively on questionnaires. The present study was an exploration of dissociative experiences in multitraumatized war-refugee youth. In this study, we used a mixed-method approach by grouping participants according to a Western-based dissociation measure (the Adolescent Dissociative Experiences Scale; Armstrong, Putnam, Carlson, Libero, & Smith, 1997), and conducting qualitative and quantitative analyses of their verbal descriptions of mental experiences related to dissociation in the aftermath of war and resettlement. The sample included 40 refugee youth, ages 13 to 21, 19 girls and 21 boys resettled in Sweden because of war and persecution. Severe trauma-related dissociation was a problem for a considerable subgroup of the sample. Some dissociative experiences were present in all the sample; others were restricted to the most dissociative group. The correlates of severe dissociation included high frequency and severity of emotional dysregulation and intensity, negative self- and body-perception, depressive mood, and experiences of detachment. Clinicians are urged to be aware of and assess trauma-related dissociation in war-refugee youth, and consider not only dissociative phenomena, but also other important processes such as emotional dysregulation.

The Auburn Linear EXperiment for Instability Studies (ALEXIS) is a laboratory plasma physics experiment used to study spatially inhomogeneous flows in a magnetized cylindrical plasma column that are driven by crossed electric (E) and magnetic (B) fields. ALEXIS was recently upgraded to include a small, secondary plasma source for a new dual source, interpenetrating plasma experiment. Using two plasma sources allows for highly localized electric fields to be made at the boundary of the two plasmas, inducing strong E × B velocity shear in the plasma, which can give rise to a regime of instabilities that have not previously been studied in ALEXIS. The dual plasma configuration makes it possible to have independent control over the velocity shear and the density gradient. This paper discusses the recent addition of the secondary plasma source to ALEXIS, as well as the plasma diagnostics used to measure electric fields and electron densities.

Graduate Students' Experiences: Developing Self-efficacy.

Laurencelle, Francine; Scanlan, Judith

2018-01-09

The nurse educator shortage continues without an increase in the numbers of graduate prepared nurses. Studies identified challenges in recruitment of nursing graduate students. No studies explore the experiences of nurses during graduate education. The framework used was Bandura's self-efficacy theory. The population for this study included 15 nurse educators with a master's or doctoral degree currently teaching in an undergraduate or graduate program in a western Canadian city. In semi-structured interviews, participants shared their experiences. Two themes emerged from the data: i) the hurdles of learning and ii) being a graduate student. The purpose of this article is to report the findings of faculty members' experiences as graduate students. Understanding these experiences will help graduate faculty understand how graduate students develop self-efficacy throughout their graduate programs. Moreover, findings of this study will help graduate students succeed in a graduate program. Finally, issues related to recruitment and retention are addressed.

Motion capture setups are used in numerous fields. Studies based on motion capture data can be found in biomechanical, sport or animal science. Clinical science studies include gait analysis as well as balance, posture and motor control. Robotic applications encompass object tracking. Today's life applications includes entertainment or augmented reality. Still, few studies investigate the positioning performance of motion capture setups. In this paper, we study the positioning performance of one player in the optoelectronic motion capture based on markers: Vicon system. Our protocol includes evaluations of static and dynamic performances. Mean error as well as positioning variabilities are studied with calibrated ground truth setups that are not based on other motion capture modalities. We introduce a new setup that enables directly estimating the absolute positioning accuracy for dynamic experiments contrary to state-of-the art works that rely on inter-marker distances. The system performs well on static experiments with a mean absolute error of 0.15 mm and a variability lower than 0.025 mm. Our dynamic experiments were carried out at speeds found in real applications. Our work suggests that the system error is less than 2 mm. We also found that marker size and Vicon sampling rate must be carefully chosen with respect to the speed encountered in the application in order to reach optimal positioning performance that can go to 0.3 mm for our dynamic study.

Depression, help-seeking perceptions, and perceived family functioning among Spanish-Dominant Hispanics and Non-Hispanic Whites.

PubMed

Keeler, Amanda R; Siegel, Jason T

2016-09-15

Guided by Beck's (1967) cognitive theory of depression, we assessed whether perceived family functioning (PFF) mediated the relationship between depressive symptomatology and help-seeking inclinations. Study 1 included 130 Spanish-Dominant Hispanics and Study 2 included 124 Non-Hispanic Whites obtained using online crowd sourcing. Participants completed measures of depressive symptomatology, PFF, and several scales measuring aspects of help seeking inclinations and self-stigma. Study 2 also included an experiment. With an eye toward potential future interventions, we assessed the malleability of PFF. Specifically, participants were randomly assigned to recall positive or negative family experiences and then PFF was measures for a second time. Both studies found PFF mediates the relationship between depressive symptomatology and the help seeking scales. Among non-depressed people, the positive manipulation improved PFF; however, among participants with elevated depressive symptomatology, writing about a positive family experience worsened PFF. With the exception of the experiment, most of the data were cross-sectional. For the experiment, it is possible that different manipulations or primes could have different effects. Whether investigating responses from Spanish-Dominant Hispanics or Non-Hispanic Whites, PFF mediates the negative relationship between heightened depressive symptomatology and familial help-seeking beliefs, as well as self-stigma. However, even though the mediation analysis offers preliminary support that increasing PFF can potentially increase help-seeking behaviors of Hispanic and Non-Hispanic White people with depression, the results of the interaction analysis, specifically the negative impact of writing about positive family memories on people with elevated depression, illustrates the challenges of persuading people with depression.

Presently, the worldwide experience with robotic pancreatic surgery (RPS) is increasing although widespread adoption remains limited. In this study, we report our initial experience with RPS. This is a retrospective review of a single institution prospective database of 72 consecutive robotic hepatopancreatobiliary surgeries performed between 2013 and 2017. Of these, 30 patients who underwent RPS were included in this study of which 25 were performed by a single surgeon. The most common procedure was robotic distal pancreatectomy (RDP) which was performed in 20 patients. This included eight subtotal pancreatectomies, two extended pancreatecto-splenectomies (en bloc gastric resection) and 10 spleen-saving-RDP. Splenic preservation was successful in 10/11 attempted spleen-saving-RDP. Eight patients underwent pancreaticoduodenectomies (five hybrid with open reconstruction), one patient underwent a modified Puestow procedure and one enucleation of uncinate tumour. Four patients had extended resections including two RDP with gastric resection and two pancreaticoduodenectomies with vascular resection. There was one (3.3%) open conversion and seven (23.3%) major (>Grade II) morbidities. Overall, there were four (13.3%) clinically significant (Grade B) pancreatic fistulas of which three required percutaneous drainage. These occurred after three RDP and one robotic enucleation. There was one reoperation for port-site hernia and no 30-day/in-hospital mortalities. The median post-operative stay was 6.5 (range: 3-36) days and there were six (20%) 30-day readmissions. Our initial experience showed that RPS can be adopted safely with a low open conversion rate for a wide variety of procedures including pancreaticoduodenectomy. © 2018 Royal Australasian College of Surgeons.

Studies examining recovery through the service users' perspectives have mainly included persons with schizophrenia or bipolar disorder. Giving voice to those with borderline personality disorder (BPD) would enrich our understanding of recovery, as their specific experiences may bring new dimensions, obstacles and facilitators. The objective of this study was to qualitatively capture the experience of recovery in women with BPD. Participants were women between 18 and 65 years old who had a diagnosis of BPD and completed at least 2 years in a program for persons with BPD. During the first meeting, they produced a picture collage, followed by an interview on their experience of recovery. The second meeting was a phone interview to discuss new thoughts. In addition, their medical records were reviewed. A thematic analysis of the interviews was conducted and organized with the Person-Environment-Occupation model. Although recovery was not the best term to name their experience, they all talked about a process towards stability and wellbeing (n = 12). Dimensions of recovery included, for example, letting go of the past (person), being involved in meaningful activities (occupation) and having healthy relationships (environment). Facilitators included social support and participation in a specialized therapy program. The main obstacle was unstable family relationships. The findings from this study showed similar dimensions to previous recovery studies, new perspectives on certain dimensions, as well as new ones. They also reinforced the importance to incorporate intervention outcomes that target the person with BPD, their social environment and meaningful occupations.

Antarctic station life: The first 15 years of mixed expeditions to the Antarctic

2017-02-01

This study examined the experiences of women who lived and worked on remote and isolated Antarctic stations for up to 15 months at a time. The study employed purposeful sampling and a longitudinal - processual approach to study women's experiences over the first 15 years of mixed gender Antarctic expeditions. The retrospective analysis was based on a semi-structured interview administered to 14 women upon their return to Australia. The results showed that women referred to the natural physical Antarctic environment as one of the best aspects of their experience and the reason they would recommend the Antarctic to their friends as a good place to work. In describing the worst aspect of their experience, women referred to aspects of Antarctic station life, including: (i) the male dominated nature of station culture; (ii) the impact of interpersonal conflict, including gender based conflict and friction between scientists and trades workers; and (iii) the lack of anonymity associated with living and working with the same group of individuals, mainly men, for up to 12 months or more. The results are discussed within the context of the evolution of Antarctic station culture and recommendations are made in terms of the demography of expeditions, expeditioner selection and recruitment and the ongoing monitoring of Antarctic station culture. The study presents a framework that can be applied to groups and teams living and working in analogous isolated, confined and extreme work environments, including outer space missions.

Participant views and experiences of participating in HIV research in sub-Saharan Africa: a qualitative systematic review.

PubMed

Nalubega, Sylivia; Evans, Catrin

2015-06-12

Human immunodeficiency virus clinical trials are increasingly being conducted in sub-Saharan Africa. There is a tension between the pressure to increase levels of research participation and the need to ensure informed consent and protection of participants' rights. Researchers need to be aware of the particular ethical issues that underpin Human immunodeficiency virus research conduct in low income settings. This necessitates hearing from those who have participated in research and who have direct experience of the research process. This review aimed to synthesize and present the best available evidence in relation to Human immunodeficiency virus research participation in sub-Saharan Africa, based on the views and experiences of research participants. The review included studies whose participants were current or former adult Human immunodeficiency virus research participants from sub-Saharan African countries. Views, experiences, attitudes, understandings, perceptions and perspectives of Human immunodeficiency virus research participants in sub-Saharan Africa. Types of studies: This review considered studies that focused on qualitative data, including, but not limited to, designs such as phenomenology, ethnography, grounded theory, action research and feminist research. A three-step search strategy was utilized. Seven databases (CINAHL, Ovid MEDLINE (R) 1946, ASSIA, PsychInfo, Web of Science, EMBASE, and African Index Medicus) were searched with no limitation to years of publication, followed by hand searching of reference lists. Only studies published in the English language were considered. Methodological quality was assessed using the Qualitative Assessment and Review Instrument developed by the Joanna Briggs Institute. Qualitative findings were extracted using the Joanna Briggs Institute Qualitative Assessment and Review Instrument. Qualitative research findings were pooled using a pragmatic meta-aggregative approach and the Joanna Briggs Institute Qualitative Assessment and Review Instrument software. Twenty-one studies were included in the review. One hundred and thirty-six findings were extracted from included studies and clustered into 14 categories based on similarities in meaning. These were further synthesized into five synthesized findings, set out below; i) Individuals are motivated to participate in Human immunodeficiency virus research due to a range of perceived benefits for themselves and others. ii) Participation in research can be associated with considerable fear and uncertainty. iii) Participation in Human immunodeficiency virus research is strongly influenced by social relationships (e.g. support or disapproval of family or friends) and social-economic and domestic factors (such as time or finances). iv). The meanings of research programs and processes are constructed within a context of existing lay beliefs, experiences and social relations associated with Human immunodeficiency virus and biomedical interventions in general. This means that local people may understand research and its processes very differently to health professionals. v) Participants' research experiences and their continued participation in Human immunodeficiency virus research are influenced by the research clinic context and the nature of their interactions with research staff. Individuals are generally willing to participate in Human immunodeficiency virus research. However their understanding of the process can be limited, and the experience may may cause anxiety or have negative consequences. Furthermore longer-term participation may become problematic due to socio-economic pressure or social commitments. The review suggests a need to develop better ways to explain research processes and to support participants, when/if they encounter problems. There is also a need to engage better with communities in order to educate them about HIV research programs. All the included studies focused on experiences around research enrolment and participation (retention); however there is a complete evidence gap on experiences of trial closure.

The effectiveness and experience of self-management following acute coronary syndrome: A review of the literature.

PubMed

Guo, Ping; Harris, Ruth

2016-09-01

To evaluate the effectiveness of interventions used to support self-management, and to explore patients' experiences after acute coronary syndrome in relation to self-management. Scoping review. Keyword search of CINAHL Plus, Medline, the Cochrane Library, and PsycINFO databases for studies conducted with adult population and published in English between 1993 and 2014. From title and abstract review, duplicated articles and obviously irrelevant studies were removed. The full texts of the remaining articles were assessed against the selection criteria. Studies were included if they were original research on: (1) effectiveness of self-management interventions among individuals following acute coronary syndrome; or (2) patients' experience of self-managing recovery from acute coronary syndrome. 44 articles (19 quantitative and 25 qualitative) were included. Most studies were conducted in western countries and quantitative studies were UK centric. Self-management interventions tended to be complex and include several components, including education and counselling, goal setting and problem solving skills which were mainly professional-led rather than patient-led. The review demonstrated variation in the effectiveness of self-management interventions in main outcomes assessed - anxiety and depression, quality of life and health behavioural outcomes. For most participants in the qualitative studies, acute coronary syndrome was unexpected and the recovery trajectory was a complex process. Experiences of making adjustment and adopting lifestyle changes following acute coronary syndrome were influenced by subjective life experiences and individual, sociocultural and environmental contexts. Participants' misunderstandings, misconceptions and confusion about disease processes and management were another influential factor. They emphasised a need for ongoing input and continued support from health professionals in their self-management of rehabilitation and recovery, particularly during the initial recovery period following hospital discharge. Evidence of the effectiveness of self-management interventions among people with acute coronary syndrome remains inconclusive. Findings from the patients' experiences in relation to self-management following acute coronary syndrome provided important insights into what problems patients might have encountered during self-managing recovery and what support they might need, which can be used to inform the development of self-management interventions. Theoretical or conceptual frameworks have been minimally employed in these studies and should be incorporated in future development and evaluation of self-management interventions as a way of ensuring clarity and consistency related to how interventions are conceptualised, operationalised and empirically studied. Further research is needed to evaluate self-management interventions among people following acute coronary syndrome for sustained effect and within different health care contexts.

Clinical practice frequently involves the practitioner touching patients' bodies in areas that are highly personal. If inappropriately performed, such intimate touch may result in much anxiety, confusion and misinterpretation. Examination of evidence is necessary to guide practice in this area to mitigate risks and foster optimal clinician-patient relations and care. The objective of this qualitative systematic review was to identify and synthesize findings on the perceptions, experiences and preferences of patients receiving a clinician's touch during intimate care and procedures INCLUSION CRITERIA TYPES OF PARTICIPANTS: The current review considered studies that included patients who had received a clinician's touch during intimate care and procedures. The current review considered qualitative studies that evaluated patients' perceptions, experiences and preferences of a clinician's touch during intimate care and procedures. The current review considered studies that collected qualitative data and included studies using designs such as phenomenology, grounded theory, ethnography, action research, qualitative description, focus group methodology and feminist research. In the absence of research studies, other text such as opinion papers and reports were considered. The current review considered studies that included patients' perceptions, experiences and preferences of a clinician's touch during intimate care and procedures. Intimate care is likely to occur in any clinical setting where patients need assistance with personal care, where physical examinations occur, or in settings were gynecologic, genitourinary, lower intestinal, dermatologic, cardiac or other procedures involving highly personal areas of the body are performed. A three-step search strategy was used to find published and unpublished studies in English from 1970 to 2016, searching various databases which included searches of reference lists of studies selected for appraisal. Included studies were assessed for methodological quality independently by two reviewers using the Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI) prior to inclusion. Of the two studies included in the review, one did not discuss ontological and epistemological assumptions, and the other did not include the personal assumptions and role of the researcher. Data were extracted using the data extraction tool from the JBI-QARI. The data extracted included details about the phenomenon of interest, populations and study methods. Qualitative findings were synthesized using JBI-QARI. Two studies were included in this review. Seven findings were organized into three categories and one synthesized finding, "clinician respect". The finding suggests that clients prefer engaged and meaningful communication prior to and during an intimate touch encounter, expect autonomy over their bodies and desire shared decision making relative to how and by whom intimate touch is provided. The synthesized finding from this review suggests that:More research is needed to explore the perceptions and preferences for intimate touch among diverse populations, generations, cultures and contexts. Particular exploration is needed for populations with additional vulnerabilities to misunderstandings, anxiety and abuse, such as pediatric and geriatric patients, and patients with physical, mental and cognitive impairments.

Objective To explore evidence on the links between patient experience and clinical safety and effectiveness outcomes. Design Systematic review. Setting A wide range of settings within primary and secondary care including hospitals and primary care centres. Participants A wide range of demographic groups and age groups. Primary and secondary outcome measures A broad range of patient safety and clinical effectiveness outcomes including mortality, physical symptoms, length of stay and adherence to treatment. Results This study, summarising evidence from 55 studies, indicates consistent positive associations between patient experience, patient safety and clinical effectiveness for a wide range of disease areas, settings, outcome measures and study designs. It demonstrates positive associations between patient experience and self-rated and objectively measured health outcomes; adherence to recommended clinical practice and medication; preventive care (such as health-promoting behaviour, use of screening services and immunisation); and resource use (such as hospitalisation, length of stay and primary-care visits). There is some evidence of positive associations between patient experience and measures of the technical quality of care and adverse events. Overall, it was more common to find positive associations between patient experience and patient safety and clinical effectiveness than no associations. Conclusions The data presented display that patient experience is positively associated with clinical effectiveness and patient safety, and support the case for the inclusion of patient experience as one of the central pillars of quality in healthcare. It supports the argument that the three dimensions of quality should be looked at as a group and not in isolation. Clinicians should resist sidelining patient experience as too subjective or mood-oriented, divorced from the ‘real’ clinical work of measuring safety and effectiveness. PMID:23293244

Application of membrane and ozonation technologies to remove color from agro-industry effluents.

2001-01-01

The results of membrane and ozonation experiments carried out on various agro-industry effluents including fermentation (baker's yeast), corrugated board, opium alkaloid and textile dying industries are presented. The experiments were performed using lab-scale membrane and ozonation reactors. Color removals were in the range of 80 to 99% for the membrane treatment studies. Ozonation experiments have shown that color removals in the range of 83 to 98% are possible for the investigated wastewaters. Final color levels were lower than 100 Pt-Co unit, which is quite acceptable aesthetically. The relative unit treatment costs of ozonation were about two times higher than membrane systems especially for very strong colored effluents including fermentation and opium alkaloid industries. The study has demonstrated that both membrane and ozonation technologies are viable options for color removal.

Women's experiences of continuous support during childbirth: a meta-synthesis.

Despite the known benefits of continuous support during childbirth, the practice is still not routinely implemented in all maternity settings and women's views and experiences might not be considered. The purpose of the study was to integrate individual studies' findings related to women's experiences of continuous support during childbirth in order to expand the understanding of the phenomenon. The review question was: What were the views and experiences of women regarding continuous support during childbirth as reported in studies that adopted qualitative or mixed research methods (with a qualitative component) using semi-structured, in-depth or focus group interviews or case studies? A detailed search was executed on electronic data bases: EBSCOhost: Medline, CINAHL, PsychINFO, SocINDEX, OAlster, Scopus, SciELO, Science Direct, PubMED and Google Scholar, using a predetermined search strategy. Reference lists of included studies were analysed to identify possible studies that were missing from electronic data bases. Pre-determined inclusion and exclusion criteria were applied during the selection of eligible sources. After critical appraisal, a total of 12 studies were included for data-extraction and meta-synthesis. Two themes were identified, namely the roles and attributes of the support persons and the type of support provided. Women's perceptions about continuous support during childbirth were influenced by the characteristics and attributes of the support person as well as the types of supportive care rendered. Women preferred someone with whom they were familiar and comfortable. Continuous support during childbirth was valued by most women. Their perceptions were influenced by the type of support person: a health professional or a lay support person. Health care institutions should include continuous support during childbirth in their policies and guidelines.

No epidemiological studies have targeted the association between experience of orthodontic treatment and symptoms of temporomandibular joint (TMJ) in a large adult population. In this study, we investigated whether experience of orthodontic treatment is associated with symptoms of TMJ in adults. We used data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V), conducted in 2011. Trained dentists asked subjects to report their experience of orthodontic treatment and symptoms of TMJ. Overall, 5936 subjects aged over 19 yr were included in this study (2528 males). The data were analyzed using the chi-square test and multiple logistic regression tests. The group with experience of orthodontic treatment had more symptoms of TMJ than the group without orthodontic experience. After adjusting for all covariates (i.e., age, sex, marital status, income, education, stress, teeth injury, and occupation), the adjusted odds ratio was 2.53 (95%CI 1.74-3.67). Experience of orthodontic treatment could be related to increased symptoms of TMJ.

Pregnancy after perinatal death is characterised by elevated stress and anxiety, increasing the risk of adverse short-term and long-term outcomes. This metasynthesis aimed to improve understanding of parents' experiences of maternity care in pregnancy after stillbirth or neonatal death. Six electronic databases were searched using predefined search terms. English language studies using qualitative methods to explore the experiences of parents in pregnancy after perinatal loss, were included subject to quality appraisal framework. Searches were initiated in December 2011 and finalised in March 2013. Studies were synthesised using an interpretive approach derived from meta-ethnography. Fourteen studies were included in the synthesis, graded A (no or few flaws, high trustworthiness; n = 5), B (some flaws, unlikely to affect trustworthiness; n = 5) and C (some flaws, possible impact on trustworthiness; n = 4). Three main themes were identified; co-existence of emotions, helpful and unhelpful coping activities and seeking reasssurance through interactions. Parents' experiences of pregnancy are profoundly altered by previous perinatal death; conflicted emotions, extreme anxiety, isolation and a lack of trust in a good outcome are commonly reported. Emotional and psychological support improves parents' experiences of subsequent pregnancy, but the absence of an evidence base may limit consistent delivery of optimal care within current services. © 2014 Royal College of Obstetricians and Gynaecologists.

Polar-Drive--Implosion Physics on OMEGA and the NIF

NASA Astrophysics Data System (ADS)

Radha, P. B.

2012-10-01

Polar drive (PD) permits the execution of direct-drive--ignition experiments on facilities that are configured for x-ray drive such as the National Ignition Facility (NIF) and Laser M'egajoule. Experiments on the OMEGA laser are used to develop and validate models of PD implosions. Results from OMEGA PD shock-timing and warm implosions are presented. Experiments are simulated with the 2-D hydrodynamic code DRACO including full 3-D ray trace to model oblique beams. Excellent agreement is obtained in shock velocity and catch-up in PD geometry in warm, plastic shells. Predicted areal densities are measured in PD implosion experiments. Good agreement between simulation and experiments is obtained in the overall shape of the compressing shell when observed through x-ray backlighting. Simulated images of the hot core, including the effect of magnetic fields, are compared with experiments. Comparisons of simulated and observed scattered light and bang time in PD geometry are presented. Several techniques to increase implosion velocity are presented including beam profile variations and different ablator materials. Results from shimmed-target PD experiments will also be presented. Designs for future PD OMEGA experiments at ignition-relevant intensities will be presented. The implication of these results for NIF-scale plasmas is discussed. Experiments for the NIF in its current configuration, with indirect-drive phase plates, are proposed to study implosion energetics and shell asymmetries.

Towards successful user interaction with systems: focusing on user-derived gestures for smart home systems.

PubMed

Choi, Eunjung; Kwon, Sunghyuk; Lee, Donghun; Lee, Hogin; Chung, Min K

2014-07-01

Various studies that derived gesture commands from users have used the frequency ratio to select popular gestures among the users. However, the users select only one gesture from a limited number of gestures that they could imagine during an experiment, and thus, the selected gesture may not always be the best gesture. Therefore, two experiments including the same participants were conducted to identify whether the participants maintain their own gestures after observing other gestures. As a result, 66% of the top gestures were different between the two experiments. Thus, to verify the changed gestures between the two experiments, a third experiment including another set of participants was conducted, which showed that the selected gestures were similar to those from the second experiment. This finding implies that the method of using the frequency in the first step does not necessarily guarantee the popularity of the gestures. Copyright © 2014 Elsevier Ltd and The Ergonomics Society.

Many products used in daily life are made by blending two or more components. The properties of such products typically depend on the relative proportions of the components. Experimental design, modeling, and data analysis methods for mixture experiments provide for efficiently determining the component proportions that will yield a product with desired properties. This article presents a case study of the work performed to develop a new rubber formulation for an o-ring (a circular gasket) with requirements specified on 10 product properties. Each step of the study is discussed, including: 1) identifying the objective of the study and requirements formore » properties of the o-ring, 2) selecting the components to vary and specifying the component constraints, 3) constructing a mixture experiment design, 4) measuring the responses and assessing the data, 5) developing property-composition models, 6) selecting the new product formulation, and 7) confirming the selected formulation in manufacturing. The case study includes some challenging and new aspects, which are discussed in the article.« less

People reporting experiences of mediumship have higher dissociation symptom scores than non-mediums, but below thresholds for pathological dissociation

PubMed Central

Wahbeh, Helané; Radin, Dean

2018-01-01

Background: Dissociative states exist on a continuum from nonpathological forms, such as highway hypnosis and day-dreaming, to pathological states of derealization and depersonalization. Claims of communication with deceased individuals, known as mediumship, were once regarded as a pathological form of dissociation, but current definitions recognize the continuum and include distress and functional disability as symptoms of pathology. This study examined the relationship between dissociative symptoms and mediumship in a large convenience sample. Methods: Secondary analyses of cross-sectional survey data were conducted. The survey included demographics, the Dissociation Experience Scale Taxon (DES-T, score range 0-100), as well as questions about instances of mediumship experiences. Summary statistics and linear and logistic regressions explored the relationship between dissociative symptoms and mediumship endorsement. Results: 3,023 participants were included and were mostly middle-aged (51 years ± 16; range 17-96), female (70%), Caucasian (85%), college educated (88%), had an annual income over $50,000 (55%), and were raised Christian (71%) but were presently described as Spiritual but not Religious (60%). Mediumship experiences were endorsed by 42% of participants, the experiences usually began in childhood (81%), and 53% had family members who reported similar experiences. The mean DES-T score across all participants was 14.4 ± 17.3, with a mean of 18.2 ± 19.3 for those claiming mediumship experiences and 11.8 ± 15.2 for those who did not (t = -10.3, p < 0.0005). The DES-T threshold score for pathological dissociation is 30. Conclusions: On average, individuals claiming mediumship experiences had higher dissociation scores than non-claimants, but neither group exceeded the DES-T threshold for pathology. Future studies exploring dissociative differences between these groups may benefit from using more comprehensive measures of dissociative symptoms as well as assessments of functional impairment, which would help in discerning between pathological and non-pathological aspects of these experiences.

Is there Complex Trauma Experience typology for Australian's experiencing extreme social disadvantage and low housing stability?

PubMed

Keane, Carol A; Magee, Christopher A; Kelly, Peter J

2016-11-01

Traumatic childhood experiences predict many adverse outcomes in adulthood including Complex-PTSD. Understanding complex trauma within socially disadvantaged populations has important implications for policy development and intervention implementation. This paper examined the nature of complex trauma experienced by disadvantaged individuals using a latent class analysis (LCA) approach. Data were collected through the large-scale Journeys Home Study (N=1682), utilising a representative sample of individuals experiencing low housing stability. Data on adverse childhood experiences, adulthood interpersonal trauma and relevant covariates were collected through interviews at baseline (Wave 1). Latent class analysis (LCA) was conducted to identify distinct classes of childhood trauma history, which included physical assault, neglect, and sexual abuse. Multinomial logistic regression investigated childhood relevant factors associated with class membership such as biological relationship of primary carer at age 14 years and number of times in foster care. Of the total sample (N=1682), 99% reported traumatic adverse childhood experiences. The most common included witnessing of violence, threat/experience of physical abuse, and sexual assault. LCA identified six distinct childhood trauma history classes including high violence and multiple traumas. Significant covariate differences between classes included: gender, biological relationship of primary carer at age 14 years, and time in foster care. Identification of six distinct childhood trauma history profiles suggests there might be unique treatment implications for individuals living in extreme social disadvantage. Further research is required to examine the relationship between these classes of experience, consequent impact on adulthood engagement, and future transitions though homelessness.

Postsecondary study and mental ill-health: a meta-synthesis of qualitative research exploring students' lived experiences.

PubMed

Ennals, Priscilla; Fossey, Ellie; Howie, Linsey

2015-04-01

The postsecondary educational experiences of students living with mental health issues are not well understood. Existing studies are generally qualitative, small and context-specific in nature, and individually have limited influence on policy and practice. To identify and synthesise the findings of qualitative studies exploring student views of studying while living with mental ill-health. A systematic search of six electronic databases including CINAHL, ERIC, PsycINFO and Medline up to March 2013 was conducted. Findings were extracted from included studies and combined using qualitative meta-synthesis to identify core processes. The search identified 16 studies from five countries, with a total of 231 participants. Meta-synthesis of the findings revealed three common core processes: (1) knowing oneself and managing one's mental illness, (2) negotiating the social space, and (3) doing the academic work required for successful postsecondary participation. Beyond the learning processes that underpin studying, these findings suggest knowing oneself and negotiating social spaces of educational settings are key processes for students living with mental ill-health seeking to survive and thrive in postsecondary education. With increased awareness of these processes, students and policy makers may conceive new ways to optimise student experiences of postsecondary study.

Human transgenerational responses to early-life experience: potential impact on development, health and biomedical research

PubMed Central

Pembrey, Marcus; Saffery, Richard; Bygren, Lars Olov

2014-01-01

Mammalian experiments provide clear evidence of male line transgenerational effects on health and development from paternal or ancestral early-life exposures such as diet or stress. The few human observational studies to date suggest (male line) transgenerational effects exist that cannot easily be attributed to cultural and/or genetic inheritance. Here we summarise relevant studies, drawing attention to exposure sensitive periods in early life and sex differences in transmission and offspring outcomes. Thus, variation, or changes, in the parental/ancestral environment may influence phenotypic variation for better or worse in the next generation(s), and so contribute to common, non-communicable disease risk including sex differences. We argue that life-course epidemiology should be reframed to include exposures from previous generations, keeping an open mind as to the mechanisms that transmit this information to offspring. Finally, we discuss animal experiments, including the role of epigenetic inheritance and non-coding RNAs, in terms of what lessons can be learnt for designing and interpreting human studies. This review was developed initially as a position paper by the multidisciplinary Network in Epigenetic Epidemiology to encourage transgenerational research in human cohorts. PMID:25062846

Trede, Franziska; McEwen, Celina; Kenny, Amanda; O'Meara, Peter

2014-05-01

We present our findings from a scoping review that sought to identify what is known about nursing and paramedic clinical supervisors' experiences of their supervision practices in rural settings. Our interest in these two groups is based on the central role that nurses and paramedics play in rural health care. Scoping reviews support identification of a broad range of literature, including all types of study designs. We adopted Arksey and O'Malley's five-stage approach: identifying the research question; identifying relevant studies; study selection; charting the data; and collating, summarising and reporting results. Databases searched included Academic Search Complete, Springer, Factiva, ProQuest, Ebsco, Informit, VOCEDplus and Scopus. Based on our research question and inclusion and exclusion criteria we selected relevant literature and summarised and reported it using Arksey and O'Malley's framework. The review yielded five articles from four countries: Sweden, Belgium, Malaysia and Australia. From this scoping review, we identified key themes related to supervisors' experiences, including clarification of expectations, support from managers and colleagues, the need for shared understanding between university, students and supervisors and required skills and competence in supervising students. © 2013.

The developmental adaptation model (Martin & Martin, 2002) provides insights into how current experiences and resources (proximal variables) and past experiences (distal variables) are correlated with outcomes (e.g., well-being) in later life. Applying this model, the current study examined proximal and distal variables associated with positive and negative affect in oldest-old adults, investigating age differences. Data from 306 octogenarians and centenarians who participated in Phase III of the Georgia Centenarian Study were used. Proximal variables included physical functioning, cognitive functioning, self-rated health, number of chronic conditions, social resources, and perceived economic status; distal variables included education, social productive activities, management of personal assets, and other learning experiences. Analysis of variance and block-wise regression analyses were conducted. Octogenarians showed significantly higher levels of positive emotion than centenarians. Cognitive functioning was significantly associated with positive affect, and number of health problems was significantly associated with negative affect after controlling for gender, ethnicity, residence, and marital status. Furthermore, four significant interaction effects suggested that positive affect significantly depended on the levels of cognitive and physical functioning among centenarians, whereas positive affect was dependent on the levels of physical health problems and learning experiences among octogenarians. Findings of this study addressed the importance of current and past experiences and resources in subjective well-being among oldest-old adults as a life-long process. Mechanisms connecting aging processes at the end of a long life to subjective well-being should be explored in future studies.

Life adverse experiences in relation with obesity and binge eating disorder: A systematic review

Palmisano, Giovanni Luca; Innamorati, Marco; Vanderlinden, Johan

2016-01-01

Background and aims Several studies report a positive association between adverse life experiences and adult obesity. Despite the high comorbidity between binge eating disorder (BED) and obesity, few authors have studied the link between trauma and BED. In this review the association between exposure to adverse life experiences and a risk for the development of obesity and BED in adulthood is explored. Methods Based on a scientific literature review in Medline, PubMed and PsycInfo databases, the results of 70 studies (N = 306,583 participants) were evaluated including 53 studies on relationship between adverse life experiences and obesity, 7 studies on post-traumatic stress disorder (PTSD) symptoms in relation to obesity, and 10 studies on the association between adverse life experiences and BED. In addition, mediating factors between the association of adverse life experiences, obesity and BED were examined. Results The majority of studies (87%) report that adverse life experiences are a risk factor for developing obesity and BED. More precisely a positive association between traumatic experiences and obesity and PTSD and obesity were found, respectively, in 85% and 86% of studies. Finally, the great majority of studies (90%) between trauma and the development of BED in adulthood strongly support this association.

2013-01-01

Current research on supercritical water processes on board the International Space Station (ISS) focuses on salt precipitation and transport in a test cell designed for supercritical water. This study, known as the Supercritical Water Mixture Experiment (SCWM) serves as a precursor experiment for developing a better understanding of inorganic salt precipitation and transport during supercritical water oxidation (SCWO) processes for the eventual application of this technology for waste management and resource reclamation in microgravity conditions. During typical SCWO reactions any inorganic salts present in the reactant stream will precipitate and begin to coat reactor surfaces and control mechanisms (e.g., valves) often severely impacting the systems performance. The SCWM experiment employs a Sample Cell Unit (SCU) filled with an aqueous solution of Na2SO4 0.5-w at the critical density and uses a refurbished High Temperature Insert, which was used in an earlier ISS experiment designed to study pure water at near-critical conditions. The insert, designated as the HTI-Reflight (HTI-R) will be deployed in the DECLIC (Device for the Study of Critical Liquids and Crystallization) Facility on the International Space Station (ISS). Objectives of the study include measurement of the shift in critical temperature due to the presence of the inorganic salt, assessment of the predominant mode of precipitation (i.e., heterogeneously on SCU surfaces or homogeneously in the bulk fluid), determination of the salt morphology including size and shapes of particulate clusters, and the determination of the dominant mode of transport of salt particles in the presence of an imposed temperature gradient. Initial results from the ISS experiments will be presented and compared to findings from laboratory experiments on the ground.

Introduction Death anxiety is a concept with greater importance among the elderly as they approach inevitability of death. Identifying the correlates of death anxiety among old people is important in order to reduce the burden of this problem. Therefore, the present study was performed with the aim to examine the association between spiritual experiences and life satisfaction with death anxiety in this stage of life. Method This cross-sectional study with descriptive-analytical design included 190 elderly people visiting the health and medical centers of Neyshabur city, Iran, during fall and winter, 2016. Participants were asked to complete three questionnaires including a 16-item spiritual experiences scale, life satisfaction index proposed by Wood and Shifor with 13 items, and a 27-item death anxiety scale developed by Aminpour. Analytical statistics (Spearman’s correlation coefficient, Pearson’s correlation coefficient) were conducted using SPSS software version 22. Results Fifty-eight percent of participants were in younger elderly age group with mean age of 68.18±7.13 years and the number of men and women was the same (95). A significant positive association between spiritual experiences and life satisfaction (r=0.2, p<0.05), a significant negative association between spiritual experiences and death anxiety (r=−0.184, p< 0.05) and a significant negative relationship between life satisfaction and death anxiety (r=−0.2, p<0.05) was found. Conclusion Based on results, it seems that reducing stressors in this stage of life including reduction of death anxiety, is possible through use of spiritual experiences and increasing life satisfaction.

Giesler, Jürgen M; Keller, Bettina; Repke, Tim; Leonhart, Rainer; Weis, Joachim; Muckelbauer, Rebecca; Rieckmann, Nina; Müller-Nordhorn, Jacqueline; Lucius-Hoene, Gabriele

2017-01-01

Background Patients often seek other patients’ experiences with the disease. The Internet provides a wide range of opportunities to share and learn about other people’s health and illness experiences via blogs or patient-initiated online discussion groups. There also exists a range of medical information devices that include experiential patient information. However, there are serious concerns about the use of such experiential information because narratives of others may be powerful and pervasive tools that may hinder informed decision making. The international research network DIPEx (Database of Individual Patients’ Experiences) aims to provide scientifically based online information on people’s experiences with health and illness to fulfill patients’ needs for experiential information, while ensuring that the presented information includes a wide variety of possible experiences. Objective The aim is to evaluate the colorectal cancer module of the German DIPEx website krankheitserfahrungen.de with regard to self-efficacy for coping with cancer and patient competence. Methods In 2015, a Web-based randomized controlled trial was conducted using a two-group between-subjects design and repeated measures. The study sample consisted of individuals who had been diagnosed with colorectal cancer within the past 3 years or who had metastasis or recurrent disease. Outcome measures included self-efficacy for coping with cancer and patient competence. Participants were randomly assigned to either an intervention group that had immediate access to the colorectal cancer module for 2 weeks or to a waiting list control group. Outcome criteria were measured at baseline before randomization and at 2 weeks and 6 weeks Results The study randomized 212 persons. On average, participants were 54 (SD 11.1) years old, 58.8% (124/211) were female, and 73.6% (156/212) had read or heard stories of other patients online before entering the study, thus excluding any influence of the colorectal cancer module on krankheitserfahrungen.de. No intervention effects were found at 2 and 6 weeks after baseline. Conclusions The results of this study do not support the hypothesis that the website studied may increase self-efficacy for coping with cancer or patient competencies such as self-regulation or managing emotional distress. Possible explanations may involve characteristics of the website itself, its use by participants, or methodological reasons. Future studies aimed at evaluating potential effects of websites providing patient experiences on the basis of methodological principles such as those of DIPEx might profit from extending the range of outcome measures, from including additional measures of website usage behavior and users’ motivation, and from expanding concepts, such as patient competency to include items that more directly reflect patients’ perceived effects of using such a website.

The experiences of acute non-surgical pain of children who present to a healthcare facility for treatment: a systematic review protocol.

PubMed

Pope, Nicole; Tallon, Mary; McConigley, Ruth; Wilson, Sally

2015-10-01

The qualitative objective of this systematic review is to identify and synthesize the best available evidence on experiences of acute non-surgical pain, including pain management, of children (between four to 18 years) when they present to a healthcare facility for treatment.The specific objectives are to identify: The International Association for the Study of Pain defines pain as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage". The pain experience is multifaceted and complex, extending beyond the physiological interpretation of a noxious stimulus, encompassing other dimensions, including; psychological, cognitive, sociocultural, affective and emotional factors. Pain can be described as chronic (persisting for three months or more) or acute (a time limited response to a noxious stimuli). Over the past 50 years clinical research has made revolutionary contributions to better understanding pediatric pain. The once pervasive erroneous notion that infants do not experience pain the same way as adults has been firmly dispelled. We now know that nervous system structures associated with the physiological interpretation of pain are functional as early as fetal development. Despite this critical knowledge and the growing global commitment to improving pediatric pain management in clinical practice, evidence repeatedly suggests that pain management remains suboptimal and inconsistent, a phenomenon commonly referred to as oligoanalgesia. Research evidence has linked poorly managed pain in the pediatric population to negative behavioral and physiological consequences later in life. Effective pain management is therefore a priority area for health care professionals. Improved understanding of children's experiences of acute non-surgical pain may lead to improved pain management and a reduction in oligoanalgesia.In the 1970s and 1980s, studies began exploring the subjective experiences of pediatric pain and discovered children's abilities to articulate their pain experiences, and to link causes and consequences of their pain. Developmental trends or age related patterns with regards to children's expressions and experiences of pain were identified. Recent studies have also recognized apparent trends in children's understanding and expressions of pain; these follow an age and cognitive development trajectory in line with Piaget's theories of development.For many children psychosocial aspects of pain, including emotions like fear, stress and anxiety, are often more unpleasant than the painful experience itself. Emotional responses such as distress and anxiety are commonly associated with the anticipation of pain, can exacerbate and intensify the pain experience, and can significantly lower a child's pain threshold. One study utilized an observational pain assessment tool to explore children's pain experiences. The findings indicated that children who underwent "non-painful" procedures (such as restraint) had equal, and in some cases higher, pain scores than those who underwent painful procedures (such as intravenous cannulation).Several studies exploring pediatric pain within health care settings (including, but not limited to, general practitioners, hospitals, emergency departments and outpatient clinics) have adopted quantitative methods, some examined parents' perspectives, and others explored nurses' perceptions. While results of such studies have added to the existing body of knowledge that supports the need to focus on improving pediatric pain management, it has been suggested that failing to ask children directly risks not capturing subjective experiences of pain from the children's perspectives in their entirety. Seeking the children's perspectives could provide a more reliable and adequate means of gaining insight into their needs and expectations when they are in pain.A single centered study in Singapore used semi-structured face-to-face interviews (n=15) to explore children's experiences of pain management postoperatively. While the children, aged between six and 12 years, identified the role of analgesia in managing their pain, they also placed significant emphasis on the role of parents and health care professionals in implementing non-pharmacological interventions in pain management. These results are relevant as they provide insights into how children experience and express pain, and their expectations of health care professionals in managing their pain. These findings draw attention to effective pain management approaches when caring for children. Similarly, a UK study adopted a cross sectional descriptive design using the draw and write technique aimed at investigating children's views on what helped when they were in pain. The children (n=71) were aged between four and 16 years. Findings revealed that children viewed themselves as active agents in pain management, while also placing significant emphasis on the importance of parents and nurses in managing their pain. In both studies, children valued nurses for social interactions, such as kindness and humor, rather than the provision of clinical care, including analgesia administration. Adjunct therapies such as distraction, visualization and music have also been shown to be effective in managing the pain experience in children.Not only do these findings demonstrate the complexity of the pain experience for the child, they also support the notion that improved pain management may come from research that is designed to better understand the entire pain experience from the child's perspective. While there are systematic reviews on interventions for managing children's pain, and one explored children's experiences in the postoperative context, none have considered children's experiences of acute non-surgical pain when they present for treatment. This qualitative systematic review aims to identify and synthesize results of studies exploring children's experiences of pain and pain management.

Although a few countries have banned flavored cigarettes (except menthol), flavors in most tobacco products remain unregulated across the globe. We conducted a systematic review of qualitative studies examining perceptions of and experiences with flavored non-menthol tobacco products. Of 20 studies on flavored tobacco products included in our qualitative systematic review, 10 examined hookah, six examined e-cigarettes, two examined little cigars and cigarillos (LCCs), and three examined other tobacco products, including cigarettes. The majority of studies, regardless of product type, reported positive perceptions of flavored tobacco products, particularly among young adults and adolescents. In six studies that assessed perceptions of harm (including hookah, LCCs, and other flavored tobacco products), participants believed flavored tobacco products to be less harmful than cigarettes. In studies that examined the role of flavors in experimentation and/or initiation (including three studies on e-cigarettes, one hookah study and one LCC study), participants mentioned flavors as specifically leading to their experimentation and/or initiation of flavored tobacco products. Given that many countries have not yet banned flavors in tobacco products, these findings add to existing research on why individuals use flavored tobacco products and how they perceive harm in flavored tobacco products, providing further support for banning non-menthol flavors in most tobacco products.

Soundy, Andrew

2014-01-01

There has been little attempt to summarise and synthesise qualitative studies concerning the experience and perception of living with Parkinson's disease. Bringing this information together would provide a background to understand the importance of an individual's social identity on their well-being and hope. Three primary aims were identified (a) understanding the importance of social identity and meaningful activities on individuals' well-being, (b) identifying factors and strategies that influence well-being and hope, and (c) establishing a model that relates to an individual's hope and well-being. Three stages were undertaken including a traditional electronic search, a critical appraisal of articles, and a synthesis of studies. Qualitative articles were included that considered the experience of living with Parkinson's disease. Thirty seven articles were located and included in the review. Five themes were identified and the themes were used to inform development of a new model of hope enablement. The current review furthered understanding of how physical symptoms and the experience of Parkinson's disease affect the individual's well-being and hope. Social identity was established as a key factor that influenced an individual's well-being. Being able to maintain, retain, or develop social identities was essential for the well-being and hope of individuals with Parkinson's disease. Understanding the factors which prevent or can facilitate this is essential. PMID:25525623

The earth's ionosphere in the altitude range of 50 to 200 km was investigated by rocket-borne sensors, supplemented by ground-based measurement. The rocket payloads included mass spectrometers, energetic particle detectors, Langmuir probes and radio propagation experiments. Where possible, rocket flights were included in studies of specific phenomena, and the availability of data from other experiments greatly increased the significance of the results. The principal ionospheric phenomena studied were: winter anomaly in radiowave absorption, ozone and molecular oxygen densities, mid-latitude sporadic-E layers, energetic particle precipitation at middle and low latitudes, ionospheric instabilities and turbulence, and solar eclipse effects in the D and E regions. This document lists personnel who worked on the project, and provides a bibliography of resultant publications.

Beginning with OSTA-1 in November 1981, and ending with Neurolab in March 1998, thirty-six shuttle missions are considered Spacelab missions because they carried various Spacelab components such as the Spacelab module, the pallet, the Instrument Pointing System (IPS), or the MPESS. The experiments carried out during these flights included astrophysics, solar physics, plasma physics, atmospheric science, Earth observations, and a wide range of microgravity experiments in life sciences, biotechnology, materials science, and fluid physics which includes combustion and critical point phenomena. In all, some 764 experiments were conducted by investigators from the United States, Europe, and Japan. These experiments resulted in several thousand papers published in refereed journals, and thousands more in conference proceedings, chapters in books, and other publications. The purpose of this Spacelab Science Results Study is to document the contributions made in each of the major research areas by giving a brief synopsis of the more significant experiments and an extensive list of the publications that were produced. We have also endeavored to show how these results impacted the existing body of knowledge, where they have spawned new fields, and, if appropriate, where the knowledge they produced has been applied.

These experiments resulted in several thousand papers published In refereed journals, and thousands more in conference proceedings, chapters in books, and other publications. The purpose of this Spacelab Science Results Study is to document the contributions made in each of the major research areas by giving a brief synopsis of the more significant experiments and an extensive list of the publications that were produced. We have also endeavored to show how these results impacted the existing body of knowledge, where they have spawned new fields, and, if appropriate, where the knowledge they produced has been applied.

Transformative practices in secondary school science classrooms: Life histories of Black South African teachers

1999-11-01

This study investigated the construction of teaching practices that are aimed at including all students in learning the key ideas of science and helping them to develop a voice for participating in the discourses in and outside of the science classroom. Such practices define what in this study is referred to as transformative practice. The study tells the stories of three Black secondary school teachers in South Africa who have worked to construct a transformative practice in their biology and physical science classrooms. Using a life history perspective, the study explored the relationships between teachers' identities and the changes in their classroom practices. Data were collected mainly through periodic interviews with the teachers and observations of their teaching practices over a period of 18 months. An important finding of the study was that the classroom practices of all three teachers were defined by three similar themes of: (1) "covering the content" and preparing their students to succeed in the national examinations, (2) developing deep conceptual understandings of the subject matter, and (3) including all students in their teaching by constructing what other researchers have called a "culturally-relevant" pedagogy. This finding was consistent despite the observed variations of context and personal histories. A major finding of this study on the question of the relationship between identity and teaching practice was that despite the importance of context, subject matter, material and social resources, another category of resources---the "resources of biography"---proved to be crucial for each of the teachers in crafting a transformative pedagogy. These "resources of biography" included such things as the teachers' own experiences of marginalization, the experiences of growing up or living in a particular culture, and the experiences of participating in certain kinds of social, political, religious or professional activities. The study suggests that it is not only the experiences that provide a person with the resources for crafting a transformative practice, but a conscious reflection on and willingness to learn from these experiences that makes them available as resources for crafting such a practice. Further research is needed to better understand what the rubric of "resources of biography" includes and to explore the interactions between these kinds of resources and the material, human, and social resources that teachers need to reform their classroom practices.

Studies on sexual trajectories of lesbian, gay, and bisexual (LGB) people generally focus on the first same-sex attraction and sexual experience, and their relation to self-identification and coming out as LGB. Relational and opposite-sex experiences are generally not taken into account. The aim of this study was to provide a more comprehensive overview of LGBs' sexual trajectories and to distinguish subsamples with different trajectories. A sample of same-sex attracted members of an online research panel (N = 3054) completed a sexual health questionnaire, including items about the timing of sexual and relational milestones. Results showed that the majority of gay men and lesbian women had same-sex sexual and relational experiences, whereas most bisexual men and women had had experiences with the opposite sex. Among gay men and lesbian women, two trajectories emerged, differing mainly on whether people had been sexually or romantically involved with opposite-sex partners, and on age of first same-sex attraction. Among those who were not exclusively attracted to the same sex, six patterns emerged, which differed especially with regard to the nature and comprehensiveness of their same-sex experiences. Within the exclusively same-sex attracted group, the trajectory with no heterosexual experiences related to higher levels of psychological adjustment. For non-exclusive sexually attracted people, trajectories including experience of same-sex relationships seem to be most beneficial. In conclusion, both relational and opposite-sex experiences proved to be important elements of LGB men and women's sexual trajectories.

Does prior psychotherapy experience affect the course of cognitive-behavioural group therapy for social anxiety disorder?

To examine whether and how different patterns of psychotherapy history (no prior therapy, successful therapy experience, and unsuccessful therapy experience) affect the outcome of future treatment among patients undergoing cognitive-behavioural group therapy for social anxiety disorder. Fifty-seven patients with varying histories of psychotherapy participating in cognitive-behavioural group treatment for social anxiety disorder were included in the study. Symptom severity (including anxiety, depression, self-efficacy, and global symptom severity) was assessed at pre- and posttreatment. A therapist-rated measure of patient therapy engagement was included as a process variable. First-time therapy patients showed more favourable pretreatment variables and achieved greater benefit from group therapy. Among patients with unsuccessful therapy experience, substantial gains were attained by those who were able to actively engage in the therapy process. Patients rating previous therapies as successful could benefit the least and tended to stagnate. Possible explanations for group differences and clinical implications are discussed. Prior psychotherapy experience affects the course of cognitive-behavioural group therapy in patients with social phobias. While patients with negative therapy experience may need extensive support in being and remaining actively engaged, those rating previous therapies as successful should be assessed very carefully and may benefit from a major focus on relational aspects.

Contextualizing mental health: gendered experiences in a Mumbai slum.

Urban mental health programmes in developing countries remain in their infancy. To serve low-income communities, research needs to consider the impact of common life experience in slums, including poverty, bad living conditions, unemployment, and crowding. Our study in the Malavani slum of Mumbai examines afflictions of the city affecting the emotional well-being and mental health of women and men with respect to gender. This is a topic for which mental health studies have been lacking, and for which psychiatric assumptions based on middle-class clinical experience may be most tenuous. This study employs ethnographic methods to show how environmental and social contexts interact in shaping local experience with reference to common mental health problems. Focusing on the social and environmental context of the mental health of communities, rather than psychiatric disorders affecting individuals, findings are broadly applicable and sorely needed to guide the development of locally appropriate community mental health programmes. Identified afflictions affecting mental health include not only access to health care, but also sanitation, addictions, criminality, domestic violence, and the so-called bar-girl culture. Although effective clinical interventions are required for mental health services to treat psychiatric disorders, they cannot directly affect the conditions of urban slums that impair mental health.

The second Control Of Flexible Structures Flight Experiment (COFS-2) includes a long mast as in the first flight experiment, but with the Langley 15-m hoop column antenna attached via a gimbal system to the top of the mast. The mast is to be mounted in the Space Shuttle cargo bay. The servo-driven gimbal system could be used to point the antenna relative to the mast. The dynamic interaction of the Shuttle Orbiter/COFS-2 system with the Orbiter on-orbit Flight Control System (FCS) and the gimbal pointing control system has been studied using analysis and simulation. The Orbiter pointing requirements have been assessed for their impact on allowable free drift time for COFS experiments. Three fixed antenna configurations were investigated. Also simulated was Orbiter attitude control behavior with active vernier jets during antenna slewing. The effect of experiment mast dampers was included. Control system stability and performance and loads on various portions of the COFS-2 structure were investigated. The study indicates possible undesirable interaction between the Orbiter FCS and the flexible, articulated COFS-2 mast/antenna system, even when restricted to vernier reaction jets.

The study aims to explore the effects of receiving active videogame (AVG) feedback and playing experience on individuals' moderate-to-vigorous physical activity (MVPA) and perceived enjoyment. This was a within-subject design study. The participants included 36 (n = 15 and 21 for boys and girls, respectively) fourth graders enrolled in a rural elementary school in southern Georgia area. The experiment lasted for 6 weeks with each week including three sessions. The participants were assigned in either front row (sensor feedback) or back row (no sensor feedback) during practice, which was alternated in different sessions. Two different dance games were played during the study with each game implemented for 3 weeks. The MVPA was measured with GT3X+ accelerometers. Physical activity (PA) enjoyment was assessed after the completion of the first two and last two sessions of each game. A repeated one-way ANOVA (analysis of variance) was used to examine the effects of AVG feedback and game on MVPA. A repeated one-way MANOVA (multivariate analysis of variance) was conducted for each game to examine the effects of experience and AVG feedback on enjoyment and MVPA. No effects of AVG feedback were found for MVPA or enjoyment (P > 0.05). The effects of experience on MVPA were found for Just Dance Kids 2014 with experience decreased MVPA (P < 0.05). Students who practiced dance AVG without receiving feedback still demonstrated positive affection and accumulated similar MVPA than when practicing while receiving feedback. Experience for certain dance games tends to decrease PA intensity.

This phenomenological qualitative study explored the experience of living with loneliness and multiple chronic conditions for rural older women in Appalachia. The study took place in 2012 in Northern West Virginia. Participants were 14 older women who were chronically ill, community dwelling, and lonely (Score of 40 or higher on the Revised 20-item UCLA Loneliness Scale). Thematic content analysis revealed four categories that contained thirteen themes: (a) negative emotions of loneliness, which included themes of sadness, disconnection, fear, anger, and worry; (b) positive emotions when not lonely, which included themes of joy with others and pride in self; (c) loss of independence and loneliness, which included themes of functional decline contributes to loneliness, burden, and gratitude for help; and (d) ways of managing loneliness, which included remembering holidays and happier moments, staying busy, and getting out. The study contributes new knowledge about the experience of anger, fear, and worry when lonely. These emotions have not extensively been identified as significant to loneliness. Future studies exploring the links between loneliness and anger, fear, worry, and negative physical health outcomes could enhance knowledge of mechanisms by which loneliness contributes to health decline. Additionally, knowing that positive emotions such as joy are described as being linked to less lonely times could inform future work that aims to diminish loneliness and enhance positive emotional states. Finally, understanding that functional impairment is described as contributing to loneliness in this population reinforces the need to assess for and address functional limitations. PMID:26594267

Optimal Design for Informative Protocols in Xenograft Tumor Growth Inhibition Experiments in Mice.

2016-09-01

Tumor growth inhibition (TGI) models are increasingly used during preclinical drug development in oncology for the in vivo evaluation of antitumor effect. Tumor sizes are measured in xenografted mice, often only during and shortly after treatment, thus preventing correct identification of some TGI model parameters. Our aims were (i) to evaluate the importance of including measurements during tumor regrowth and (ii) to investigate the proportions of mice included in each arm. For these purposes, optimal design theory based on the Fisher information matrix implemented in PFIM4.0 was applied. Published xenograft experiments, involving different drugs, schedules, and cell lines, were used to help optimize experimental settings and parameters using the Simeoni TGI model. For each experiment, a two-arm design, i.e., control versus treatment, was optimized with or without the constraint of not sampling during tumor regrowth, i.e., "short" and "long" studies, respectively. In long studies, measurements could be taken up to 6 g of tumor weight, whereas in short studies the experiment was stopped 3 days after the end of treatment. Predicted relative standard errors were smaller in long studies than in corresponding short studies. Some optimal measurement times were located in the regrowth phase, highlighting the importance of continuing the experiment after the end of treatment. In the four-arm designs, the results showed that the proportions of control and treated mice can differ. To conclude, making measurements during tumor regrowth should become a general rule for informative preclinical studies in oncology, especially when a delayed drug effect is suspected.

Domestic violence is one of the most prevalent problems linked to HIV. Domestic violence in HIV-infected women has not been sufficiently explored, particularly in developing countries including Iran. This study aimed to explore the lived experience of domestic violence in Iranian HIV-infected women. A qualitative approach was used to conduct the study. Data were collected through semi-structured, in-depth interviews with ten HIV-infected women and were analyzed using content analysis. During the data analysis, four main themes emerged including, “regretful past”, “disappointing future”, “loneliness”, and “no other option”, which refer to the condition that the participants experienced in their lives due to challenges that mainly stem from the experience of HIV-related domestic violence. HIV infection can be a risk factor for domestic violence. Health care providers need to address domestic violence during the assessment of HIV-infected women and make appropriate referrals for abused women. PMID:26156897

This study examined roles and experiences of fathers of children with chronic kidney disease (CKD). Based on interpretive description, semistructured interviews were conducted with 22 fathers of children receiving a range of treatments (transplant, peritoneal dialysis, hemodialysis, and CKD not requiring renal replacement therapy). Fathers described various experiences and means of adjusting to shifts associated with pediatric CKD. These included loss of personal control, a sense of personal isolation, and a stance of remaining strong amidst personal suffering. Nuanced differences according to modality of CKD care were identified. Fathers engaged in strategies that fostered coping, such as remaining positive and taking charge. They conveyed deep love for their child, and demonstrated ingenuity and persistence in care. Few resources of support were accessed by fathers. Study recommendations invite holistic approaches to health care, with improved resources for families—including fathers—in addressing the needs of this population. PMID:28508021

Studies from rockets directed toward establishing the solar X-ray fluxes during the 7 March 1970 total eclipse over the North American continent are reported. A map of the eclipse path is presented. The measured absorption profiles for the residual X-rays are useful in establishing their contribution to the D and E region ionization during the eclipse. The studies were performed with two Nike-Apache payloads launched over Wallops Island, Virginia. In addition to three X-ray detectors in the 1 to 8A, 8 to 20A and 44 to 60A bands, there was included in the payloads two additional experiments. These were an electric field experiment and an epithermal photoelectron experiment. The X-ray instrumentation, payload description, flight circumstances and finally, the X-ray results obtained are described. The various computer codes employed for the purpose of reducing the telemetered data as well as the eclipse codes are included.

As part of the internationalization of higher education, increasing numbers of international doctoral students are coming to study in British nursing schools. This paper reports on a small-scale exploratory survey that sought to investigate the educational experiences of these students and their supervisors in one British School of Nursing. Both staff and students saw great value in international education. However both groups identified the need for greater support to facilitate adjustment in a number of areas, including: understanding the PhD process, studying in a second language, working within a different academic culture, managing the supervision relationship, and finding a sense of community. This was a small study, but the findings confirm key issues identified in the limited available literature. Recommendations include staff training and the development of additional in-puts for students. Future research should include qualitative, longitudinal and multi-site studies to more thoroughly assess the process and outcomes of international doctoral education in nursing.

Background Cultural competency is now a core requirement for mental health professionals working with culturally diverse patient groups. Cultural competency training may improve the quality of mental health care for ethnic groups. Methods A systematic review that included evaluated models of professional education or service delivery. Results Of 109 potential papers, only 9 included an evaluation of the model to improve the cultural competency practice and service delivery. All 9 studies were located in North America. Cultural competency included modification of clinical practice and organizational performance. Few studies published their teaching and learning methods. Only three studies used quantitative outcomes. One of these showed a change in attitudes and skills of staff following training. The cultural consultation model showed evidence of significant satisfaction by clinicians using the service. No studies investigated service user experiences and outcomes. Conclusion There is limited evidence on the effectiveness of cultural competency training and service delivery. Further work is required to evaluate improvement in service users' experiences and outcomes. PMID:17266765

To explore the men's beliefs, values, attitudes and experiences towards contraceptives. The promotion of male participation in contraceptive practices requires the knowledge and consideration of the beliefs, values, attitudes and experiences involved. The systematic review of the literature focusing on these themes can be useful for the evidence-based health care. A systematic review of qualitative studies. Studies published between 1994 until 2011 (inclusive) were included. The participants included men from all cultures, ethnic backgrounds and religions who have expressed their beliefs, values, attitudes and experiences regarding male contraceptives. The databases CINAHL, PubMed, PsycINFO, SciELO, LILACS and MedCarib were explored. The appraisal of primary studies, carried out through the JBI-QARI (Qualitative Assessment and Review Instrument) resulted in the inclusion of 16 studies in this systematic review. The set of statements of beliefs, values, attitudes and experiences regarding contraceptives resulted in five synthesis: (1) contraceptive behaviour is influenced by religious, family and social backgrounds; (2) gendered, male-centred values predominate in contraceptive behaviours; (3) the sense of invulnerability influences contraceptive behaviours; (4) strong obstacles should be overcome to use contraceptives; (5) behaviours, decision-making and experiences regarding male contraceptives. The male beliefs and values regarding contraceptives are strongly influenced by religious, family and social backgrounds, and their attitudes in this scope are male centred. A deeper male consciousness regarding contraceptive responsibility should be promoted. It requires the knowledge of the men's personal backgrounds regarding contraceptives because they can be diverse according to family, social and cultural contexts. The consideration of the men's personal perspective is essential in the planning and implementation of reproductive health care. These aspects are essential for the concretisation of the evidence-based health care, a current challenge worldwide. © 2013 John Wiley & Sons Ltd.

A case study of collaboration in science education: Integrating informal learning experiences into the school curriculum

NASA Astrophysics Data System (ADS)

Robertson, Amy Michelle

This is a study of a collaboration between multiple stakeholders in science education for the purpose of creating educational field trip experiences. The collaboration involves four major facets of science education: formal education at the elementary and university levels, informal education, and educational research. The primary participants in the collaboration include two elementary school teachers, a scientist from a local university, an informal educator from an environmental education site, and the researcher acting as a participant observer. The coming together of these different sides of science education provided a unique opportunity to explore the issues and experiences that emerged as such a partnership was formed and developed. Strongly influenced by action research, this study is a qualitative case study. The data was collected by means of observation, semi-structured interviews, and written document review, in order to provide both a descriptive and an interpretive account of this collaboration. The final analysis integrates a description of the participants' experiences as evidenced in the data with the issues that arose from these experiences. The evolution of the collaborators' roles was examined, as was the development of shared vision. In this study, there were several factors that significantly affected the progress towards a shared vision and a successful collaboration. These factors include time, communication, understanding others' perspectives, dedication and ownership, as well as the collaborative environment. Each collaborator benefited both professionally and personally from their participation in the collaboration. In addition, the students gained cognitively, affectively, and socially from the educational experiences created through the collaboration. Steps, such as working towards communication and understanding others' perspectives, should continue to be taken to ensure the collaboration continues beyond the term of the current key participants.

Clinical literature on incest trauma assumes a homogeneity of experience of all incest survivors including women of color. Experiences relating to community, culture, and family need to be acknowledged as salient aspects of the experiences of women of color who are also incest survivors. Twelve participants were interviewed regarding their experiences related to disclosure and coping. Participants described value systems, community mindedness, social attitudes, negative consequences amongst other social and cultural issues as factors affecting incest disclosure. Participants described cognitive reframing, determination and separation from the perpetrator as ways of coping with incest.

2013-09-01

Addressing gaps in the research, the current study assesses the impact of a community-based child sexual abuse prevention program on known survivor knowledge/skills, disclosures, and subjective experience. Methodologically, novel measures of program fidelity and implementation cost are applied. A pre- posttest wait-list control design was utilized with intervention (n = 10) and comparison groups (n = 10). Measures included a standardized knowledge/skill questionnaire, coding of disclosures, subjective experience questionnaires, in-depth interviews, video analysis of program adherence, and a measure of cost. Analysis involved nonparametric tests and thematic analysis of interview and video data. Cost was calculated for the group and per survivor. Survivors achieved significant gains in knowledge/skills, made further disclosures, and were positive about their program experience. No gains were identified in the control group. Costs were small. Future studies need to explore survivor experience of programs delivered in classrooms.

A Thematic Inquiry into the Burnout Experience of Australian Solo-Practicing Clinical Psychologists

PubMed Central

Hammond, Trent E.; Crowther, Andrew; Drummond, Sally

2018-01-01

Objective: Burnout is conceptualized as a syndrome that consists of emotional exhaustion, depersonalization, and decreased personal accomplishment. Despite the increased frequency and severity of burnout in the Western world, there is limited published research regarding the experiences of clinical psychologists who have had burnout. The present study examines clinical psychologists’ different experiences of burnout in Australia. Design and Methods: In the year 2015, six privately practicing and solo-employed clinical psychologists provided rich qualitative data by participating in semi-structured interviews. Thematic analysis was the method used to analyze clinical psychologists’ natural accounts of their burnout experiences. Using NVivo, emerging themes were identified through coding ‘first order constructs’ and then axial code ‘second order constructs.’ Findings: Clinical psychologists indicated that their roles are demanding and a diverse range of symptoms, including the enduring effects of burnout, mental stress, fatigue, decreased personal accomplishment, negative affect, depersonalization, reduced productivity and motivation, and insomnia. They identified precursors of burnout, including excessive workload and hours of work, life stresses, mismanaged workload, and transference. Clinical psychologists suggested that protective factors of burnout include knowledge and years worked in direct care, and trusting and long-term relationships. They indicated that the barriers to overcoming burnout include the fallacy that their clients’ expectations and needs are more important than their own, the financial cost of working in private practice, contemporary knowledge and inadequate education regarding self-care, and time constraints. Discussion and Conclusion: The findings presented in this study provide psychologists and other health professionals with an insight about the burnout experience and inform professionals of the mental shortcomings of working as a solo-practicing clinical psychologist. Findings from this study should lead to an increased understanding of the complexities of burnout, and ultimately reduced cases of burnout, absenteeism, and staff disengagement. PMID:29403402

Fall-related experiences of stroke survivors: a meta-ethnography.

2017-04-01

Health professionals view falls after stroke as common adverse events with both physical and psychological consequences. Stroke survivors' experiences are less well understood. The aim of this systematic review was to explore the perception of falls-risk within the stroke recovery experience from the perspective of people with stroke. A systematic literature search was conducted. Papers that used qualitative methods to explore the experiences of individuals with stroke around falls, falls-risk and fear of falling were included. Two reviewers independently assessed the methodological quality of papers. Meta-ethnography was conducted. Concepts from each study were translated into each other to form theories that were combined through a "lines-of-argument" synthesis. Four themes emerged from the six included qualitative studies: (i) Fall circumstances, (ii) perception of fall consequences, (iii) barriers to community participation and (iv) coping strategies. The synthesis revealed that stroke survivors' perceived consequences of falls exist on a continuum. Cognitive and emotional adjustment may be required in the successful adoption of coping strategies to overcome fall-related barriers to participation. Stroke survivors' fall-related experiences appear to exist within the context of activity and community participation. Further research is warranted due to the small number of substantive studies available for synthesis. Implications for Rehabilitation Health care professionals should recognize that cognitive and emotional adjustment may berequired for stroke survivors to accept strategies for overcoming falls-risk, including dependenceon carers and assistive devices. Several factors in addition to physical interventions may be needed to minimize falls-risk whileincreasing activity participation. These factors could include increasing public awareness about the effects of stroke and falls-risk,and ensuring access to psychological services for stroke survivors. Rehabilitation professionals should reflect on whether they perceive there to be an appropriatelevel of fear of falling post-stroke. They should understand that stroke survivors might not conceptualize falls-risk in this way.

The care needs of women with gynecological cancer are complex and change over the course of their cancer journey. Specialist nurses are well positioned to play a role in meeting the needs of women with gynecological cancer although their role and scope of practice have not been well defined. As patients are a key stakeholder, understanding their experience of care is an important step in better defining the role and scope of practice of specialist nurses in gynecological oncology in Australia and New Zealand. This review sought to consider gynecological cancer patients' experiences of specialist nursing care. Exploring the patient's experience of care by a specialist nurse is one step in the process of better defining the role and scope of practice of specialist gynecological-oncology nurses in Australia and New Zealand. This review included studies with a focus on women with gynecological cancer who had been cared for by a specialist nurse. Studies of women with gynecological cancer at any point on the continuum of care from pre-diagnosis to survivorship or end of life, including those with a recurrence of the disease, were included, with no limit to the duration of care received for inclusion in the review. Studies that explored how women with gynecological cancer experience the care and interventions of specialist nurses were included. Qualitative studies including, but not limited to, designs such as phenomenology, grounded theory, ethnography, action research and feminist research were considered for review. This review also considered the qualitative components of mixed method studies. Research conducted in any country was considered for inclusion in this review providing that the study was reported in English. Studies conducted in any setting including, but not limited to, acute hospitals, outpatient/ambulatory clinics, chemotherapy or radiotherapy units, support groups, palliative care units or the patient's home were included. A three-step search strategy was utilized in this review. An initial limited search of MEDLINE and CINAHL was undertaken followed by a comprehensive search using all identified keywords and index terms across all included databases. The reference lists of all identified reports and articles were hand searched for additional studies. Each paper was independently assessed by two independent reviewers for methodological validity prior to inclusion in the review using the standardized critical appraisal instrument from the Joanna Briggs Institute the Qualitative Assessment and Review Instrument. When disagreement arose between the reviewers, the given paper was independently appraised by a third reviewer. Data were extracted from papers included in the review using the standardized data extraction tool from Joanna Briggs Institute the Qualitative Assessment and Review Instrument. Data extraction was completed independently by two reviewers. Extracted findings from seven included papers were grouped according to similarity in meaning from which 11 categories were developed. These categories were then subjected to a meta-synthesis that produced a set of three synthesized findings. Key findings were extracted from six included papers and classified as unequivocal (U) or credible (C). A total of 30 findings were extracted and aggregated into 11 categories based on similarity in meaning. From the 11 categories, three synthesized findings were developed: i) Tailored care: specialist nurses play a role in understanding and meeting the individual needs of women with gynecological cancer; ii) Accessible care: specialist nurses guide women with gynecological cancer along the continuum of care and are an easily accessed source of knowledge and support; iii) Dependable expertise: women with gynecological cancer express trust and reassurance in the experience and expertise of the specialist nurse. This systematic review synthesized the findings of seven studies that captured the experiences of women with gynecological cancer who received care from a specialist nurse. The specialist nurse offers tailored, accessible and expert care to women with gynecological cancer. From the synthesis it is recommended that women with gynecological cancer have access to the services of a specialist nurse at key points on the continuum of care, that specialist nurses provide information to patients on their disease and treatment in the form preferred by the patient and ensure that this information has been understood, and that specialist nurses are afforded time to spend with patients to enable greater exploration and identification of patient needs and the provision of personalized care. Further study that considers other key stakeholders in the specialist nurse role in gynecological oncology is recommended in order to gain a full understanding of specialist nurses' contribution to the care of women with gynecological cancer. Additionally, it is recommended that further studies be conducted to seek the perspectives of women with gynecological cancer from culturally and linguistically diverse backgrounds and Indigenous populations on specialist nursing care as they appear to be under-represented in current research.

Learning and understanding physics requires more than studying physics texts. It requires doing physics. Doing research is a key opportunity for students to connect physical principles with their everyday experience. A powerful way to introduce students to research and technique is through subjects in which they might find interest. Presented is an experiment that serves to introduce an advanced undergraduate or high school student to conducting research in acoustics via an experiment involving a standard dreadnought acoustic guitar, recording industry-related equipment, and relevant industrial analysis software. This experimental process is applicable to a wide range of acoustical topics including both acoustic and electric instruments. Also, the student has a hands-on experience with relevant audio engineering technology to study physical principles.

Requirements for spaceflight experments which involve higher plants were determined. The plants are studied for use in controlled ecological life support systems (CELSS). Two categories of research requirements are discussed: (1) the physical needs which include nutrient, water and gas exchange requirements; (2) the biological and physiological functions which affect plants in zero gravity environments. Physical problems studies are given the priority since they affect all biological experiments.

Consumers' view on determinants to food satisfaction. A qualitative approach.

PubMed

Andersen, Barbara Vad; Hyldig, Grethe

2015-12-01

The objective of this study was to gain a better understanding of the multiple determinants to food satisfaction from a consumer perspective. The study includes two focus groups with a total of 20 consumers varying in gender, age, employment and food interest. The results were divided into sections based on the main themes that arose from analysing the focus groups; i) sensory properties, ii) physical wellbeing, iii) expectations and desires, iv) the food context and v) comparison of the importance of the various determinants to satisfaction. Factors important for food satisfaction appear before as well as during and after intake. Before intake, the important factors are; expectations and desires based on memories about previous food experiences and the context in which the food is perceived. Physical wellbeing was mentioned important for the feeling of satisfaction, included in physical wellbeing is the experience of an appropriate energy level after intake. In general the sensory experience seems to be the primary determinant to satisfaction. The hedonic experience of eating could be enhanced by the social company and knowledge about the food inclusive health value and origin. Findings from the study will prospectively be used to develop a questionnaire. The questionnaire will be applied in case studies to measure factors influential in food satisfaction.

The experience of living with advanced-stage cancer: a thematic synthesis of the literature.

PubMed

García-Rueda, N; Carvajal Valcárcel, A; Saracíbar-Razquin, M; Arantzamendi Solabarrieta, M

2016-07-01

The aim of the study was to understand the experience of people living with advanced-stage cancer through literature. The search included The Cochrane Library, PubMed, PsycInfo, CINAHL and Cuiden. Thirteen studies were included. A qualitative meta-synthesis was conducted. One thread emerged from the thematic synthesis: the desire to live as normally as possible, despite being aware of the proximity of death. Three themes also emerged: "a process that is unique" with its four sub-themes; "support network" and "health context," each of them having two sub-themes. This study concludes that living with advanced-stage cancer is a unique and complex process which has both positive and negative aspects. The review provides a comprehensive view of the experience, which considers the importance of the support network and the health context in which the person lives. In this study, "normalcy" is the adjustment to the new reality and living as closely as possible to the way one lived before the disease, while developing a new relationship with being finite and death. A better understanding of the experience of living with advanced-stage cancer will help health professionals to identify the needs of the patients in order to plan individual, high-quality care. © 2016 John Wiley & Sons Ltd.

The impact of residents' training in Electronic Medical Record (EMR) use on their competence: report of a pragmatic trial.

Even though Electronic Medical Records (EMRs) are increasingly used in healthcare organizations there is surprisingly little theoretical work or educational programs in this field. This study is aimed at comparing two training programs for doctor-patient-computer communication (DPCC). 36 Family Medicine Residents (FMRs) participated in this study. All FMRs went through twelve identical simulated encounters, six pre and six post training. The experiment group received simulation based training (SBT) while the control group received traditional lecture based training. Performance, attitude and sense of competence of all FMRs improved, but no difference was found between the experiment and control groups. FMRs from the experiment group evaluated the contribution of the training phase higher than control group, and showed higher satisfaction. We assume that the mere exposure to simulation served as a learning experience and enabled deliberate practice that was more powerful than training. Because DPCC is a new field, all participants in such studies, including instructors and raters, should receive basic training of DPCC skills. Simulation enhances DPCC skills. Future studies of this kind should control the exposure to simulation prior to the training phase. Training and assessment of clinical communication should include EMR related skills.

Harrison, Tracie

2013-01-01

Purpose The objective of this study was to examine disablement as experienced by young adult African American men and women with permanent mobility impairment. Methods This study included a sample of 5 male and 5 female participants ranging in age from 22 to 39. An exploratory descriptive design and qualitative methods, including interviews and fieldnotes, were used. Interview data was analyzed using the process of inductive qualitative content analysis. Results Basic desires for independence, shared intimacy, and psychological and physical health were not diminished by physical limitations. The disablement experience of this group is reflected in the themes of “Cumulative Losses” and “Sustained Desires.” The findings of this study describe the high level of motivation that young adult African American men and women with disabilities have to improve levels of health and well-being within the context of their impairments. Conclusion This study provides a better understanding of the contextual factors and experiences that may contribute to the development of further disability and subsequent health-related problems over time. Increased knowledge of the disablement experience of these young men and women may assist health care entities and social service providers in improving health care and rehabilitation efforts targeting this group.

The contraceptive efficacy of Implanon: a review of clinical trials and marketing experience.

PubMed

Graesslin, Olivier; Korver, Tjeerd

2008-06-01

To evaluate the contraceptive efficacy of the etonogestrel-releasing implant Implanon as assessed in international studies and during nine years of marketing experience. The analysis included 11 international studies and data collected during nine years of marketing experience (1998--2007). Seven of these studies were noncomparative; the four other studies included the 6-rod levonorgestrel implant system or an intrauterine device as a comparator. All studies except one were of at least two years in duration, and all had contraceptive efficacy as the objective. Market data were provided unsolicited to Organon, part of Schering Plough. The integrated efficacy analysis included 923 non-breastfeeding women who were exposed to the implant for 24,100 cycles. No in-treatment or pretreatment pregnancies were reported. Fifty posttreatment pregnancies were reported, six of which occurred within 14 days of implant removal, indicating that fertility had quickly returned. Over a nine-year marketing period an overall pregnancy rate of 0.049 per 100 implants sold (estimated Pearl Index = 0.031 based on all pregnancies reported) was calculated. When only counting contraceptive method failures the pregnancy rate amounts to 0.010 per 100 implants sold (estimated Pearl Index = 0.006). Implanon is a highly effective and quickly reversible subdermal method of long-acting hormonal contraception for women. Typical use of this implant achieves a contraceptive protection exceeding 99%.

Objects and events as determinants of parallel processing in dual tasks: evidence from the backward compatibility effect.

PubMed

Ellenbogen, Ravid; Meiran, Nachshon

2011-02-01

The backward-compatibility effect (BCE) is a major index of parallel processing in dual tasks and is related to the dependency of Task 1 performance on Task 2 response codes (Hommel, 1998). The results of four dual-task experiments showed that a BCE occurs when the stimuli of both tasks are included in the same visual object (Experiments 1 and 2) or belong to the same perceptual event (Experiments 3 and 4). Thus, the BCE may be modulated by factors that influence whether both task stimuli are included in the same perceptual event (objects, as studied in cognitive experiments, being special cases of events). As with objects, drawing attention to a (selected) event results in the processing of its irrelevant features and may interfere with task execution. (c) 2010 APA, all rights reserved.

Every year, 14 % of patients in Norwegian hospitals experience adverse events, which often have health-damaging consequences. The government, hospital management and health personnel attempt to minimize such events. Limited research on the first-hand experience of the patients affected is available. The aim of this study is to present patients' perspectives of the occurrence of, disclosure of, and healthcare organizations' responses to adverse events. Findings are discussed within a social constructivist framework and with reference to principles of open disclosure policy. This qualitative study with an explorative descriptive design included fifteen in-depth interviews with former patients recruited by the Health and Social Services ombudsmen in the two northernmost counties of Norway. Inclusion criteria were as follows: 1) experience of adverse events in connection with surgical, orthopedic or medical treatment in general hospitals; 2) men and women; 3) aged 20-70; and 4) a minimum of one year since the event occurred. Transcribed audio-recorded interviews were analyzed through qualitative content analysis. The analysis revealed three main topics regarding patients' experiences of adverse events: 1) ignored concerns or signs of complications; 2) lack of responsibility and error correction; and 3) lack of support, loyalty and learning opportunities. Patients had to struggle to demonstrate the error that had occurred and to receive the necessary treatment and monitoring in the aftermath of the events. Patient narratives reveal a lack of openness, care and responsibility in connection with adverse events. Conflicting power structures, attitudes and established procedures may inhibit prevention, learning and patient safety work in spite of major efforts and good intentions. Attitudes in day-to-day patient care and organizational procedures should be challenged to invite patients into open disclosure processes and include them in health and safety work to a greater extent. The study's small sample of self-selected participants limits the generalizability of the findings, and future studies should include a larger number of patients as well as professional perspectives.

The prevalence of dementia is increasing, especially in Asia. Caregivers of people with dementia are at greater risk of psychological morbidity; however, most studies on caregiving have been conducted in Western populations. As a caregiver's experience can be influenced by cultural factors, this needs exploring further. This study explored the lived experience of caregivers of dementia patients in Singapore and the impact of caring on their sense of self. Six Chinese female spousal caregivers were interviewed and their experiences were analyzed using interpretative phenomenological analysis (IPA). Four super-ordinate themes were identified: impact of caregiving, acceptance of destiny, taking control, and view of self. The findings reflected the influence of Confucian values. Clinical implications are discussed, including more culturally sensitive services.

Spaceflight experiments since 1981 have demonstrated that certain cell functions are altered by micro-g. Biophysical models suggest that cell membranes and organelles should not be affected directly by gravity, however, the chemical microenvironment surrounding the cell and molecular transport could be altered by reduced gravity. Most experiments have used suspended live cells in small chambers without stirring or medium exchange. Flight results include increased attachment of anchorage-dependent human cells to collagen coated microcarriers, reduced secretion of growth hormone from pituitary cells, decreased mitogenic response of lymphocytes, increased Interferon-alpha by lymphocytes, increased Interleukin-1 and Tumor Necrosis Factor secretion by macrophages. Related experiments on cells immediately postflight and on procaryotic cells have shown significant changes in secretory capacity, cell proliferation, differentiation and development. Postulated mechanism include altered cell-cell interactions, altered calcium ion transport, effects on cell cytoskeleton, transport of transmitters and interactions with receptors. The discussion includes use of new molecular methods, considerations for cell environmental control and a preview of several experiments planned for the Shuttle and Spacelab flights to study the basic effects of microgravity on cellular physiology and potential interactions of spaceflight with radiation damage and cellular repair mechanisms.

The Century Experiment at the Russell Ranch Sustainable Agriculture Facility at the University of California, Davis provides long-term agroecological data from row crop systems in California's Central Valley starting in 1993. The Century Experiment was initially designed to study the effects of a gradient of water and nitrogen availability on soil properties and crop performance in ten different cropping systems to measure tradeoffs and synergies between agricultural productivity and sustainability. Currently systems include 11 different cropping systems-consisting of four different crops and a cover crop mixture-and one native grass system. This paper describes the long-term core data from the Century Experiment from 1993-2014, including crop yields and biomass, crop elemental contents, aerial-photo-based Normalized Difference Vegetation Index data, soil properties, weather, chemical constituents in irrigation water, winter weed populations, and operational data including fertilizer and pesticide application amounts and dates, planting dates, planting quantity and crop variety, and harvest dates. This data set represents the only known long-term set of data characterizing food production and sustainability in irrigated and rainfed Mediterranean annual cropping systems.

Doctors, especially doctors-in-training such as residents, make errors. They have to face the consequences even though today's approach to errors emphasizes systemic factors. Doctors' individual characteristics play a role in how medical errors are experienced and dealt with. The role of gender has previously been examined in a few quantitative studies that have yielded conflicting results. In the present study, we sought to qualitatively explore the experience of female residents with respect to medical errors. In particular, we explored the coping mechanisms displayed after an error. This study took place in the internal medicine department of a Swiss university hospital. Within a phenomenological framework, semi-structured interviews were conducted with eight female residents in general internal medicine. All interviews were audiotaped, fully transcribed, and thereafter analyzed. Seven main themes emerged from the interviews: (1) A perception that there is an insufficient culture of safety and error; (2) The perceived main causes of errors, which included fatigue, work overload, inadequate level of competences in relation to assigned tasks, and dysfunctional communication; (3) Negative feelings in response to errors, which included different forms of psychological distress; (4) Variable attitudes of the hierarchy toward residents involved in an error; (5) Talking about the error, as the core coping mechanism; (6) Defensive and constructive attitudes toward one's own errors; and (7) Gender-specific experiences in relation to errors. Such experiences consisted in (a) perceptions that male residents were more confident and therefore less affected by errors than their female counterparts and (b) perceptions that sexist attitudes among male supervisors can occur and worsen an already painful experience. This study offers an in-depth account of how female residents specifically experience and cope with medical errors. Our interviews with female residents convey the sense that gender possibly influences the experience with errors, including the kind of coping mechanisms displayed. However, we acknowledge that the lack of a direct comparison between female and male participants represents a limitation while aiming to explore the role of gender.

Older men's experiences of sleep in the hospital.

Lee, Chau Yuen; Low, Lisa Pau Le; Twinn, Sheila

2007-02-01

The aim of this study was to examine the sleep experiences of older patients during a period of hospitalization on an extended care ward. Hospital wards have been demonstrated as environments that are not conducive to sleep for patients. Findings highlight the difficulties of falling asleep and getting insufficient sleep as the major causes of sleep disturbances. Such studies limit themselves to patients of Intensive Care Units and acute care settings. Relatively little is known about understanding the sleep experiences of older patients whilst hospitalized on extended care wards. An exploratory qualitative design was used with a convenience sample of six Chinese male informants, recruited from an extended care ward of a Rehabilitation Hospital in Hong Kong. Multiple data collection methods were used, including repeated semi-structured interviews and a one-week sleep diary. The findings demonstrated that all informants experienced dynamic changes in their sleeping patterns during hospitalization, resulting in sleep disruption and deprivation. The public nature of the ward environment and perceived sense of helplessness significantly interfered with sleep. Some cultural beliefs and practices were perceived by older patients to be associated with the quality of their sleep experiences. The findings contributed to an understanding of the sleep experiences of older patients during hospitalization. Implications for nursing practice indicate the significance of including focused sleep assessment of patients during admission into the ward, so strategies perceived by older patients as being able to improve sleep would be included as part of the usual ward routine and nursing practice, where possible.

Field Research in the Teaching of Undergraduate Soil Science

Several studies have demonstrated that undergraduate students benefit from research experiences. Benefits of undergraduate research include 1) personal and intellectual development, 2) more and closer contact with faculty, 3) the use of active learning techniques, 4) creation of high expectations, 5) development of creative and problem-solving skills, 6) greater independence and intrinsic motivation to learn, and 7) exposure to practical skills. The scientific discipline also benefits, as studies have shown that undergraduates who engage in research experiences are more likely to remain science majors and finish their degree program (Lopatto, 2007). Research experiences come as close as possible to allowing undergraduates to experience what it is like to be an academic or research member of their profession working to advance their discipline. Soils form in the field, therefore, field experiences are very important in developing a complete and holistic understanding of soil science. Combining undergraduate research with field experiences can provide extremely beneficial outcomes to the undergraduate student, including increased understanding of and appreciation for detailed descriptions and data analysis as well as an enhanced ability to see how various parts of their undergraduate education come together to understand a complex problem. The experiences of the authors in working with undergraduate students on field-based research projects will be discussed, along with examples of some of the undergraduate research projects that have been undertaken. In addition, student impressions of their research experiences will be presented. Reference Lopatto, D. 2007. Undergraduate research experiences support science career decisions and active learning.

The Susan G. Komen for the Cure Tissue Bank at the IU Simon Cancer Center (KTB) was established in 2007 with funding from Susan G. Komen for the Cure to provide scientists with a resource for normal breast tissue. To date, nearly 3,500 women have donated their healthy breast tissue to the bank, but little is known about their perspectives. This study was designed to examine their motivations, concerns, and experiences. We conducted brief interviews with donors (n = 221) to investigate their donation-related motivations, concerns, and experiences. Donor responses were coded and quantitatively analyzed (descriptive statistics and χ(2)). The most frequent motivation to donate (48% of donors) was personal connection to a breast cancer patient/survivor. A majority of donors (60%) were unconcerned about donation before the event; reported concerns included pain, fear, and dislike of surgical procedures. The most frequent positive experiences were minimal pain and positive behavior by KTB staff and volunteers. A majority of donors (61%) reported no negative experience, but reported negative experiences included the biopsy machine and anesthetic. Younger donors (ages 18-24) reported more concerns and negative experiences than older donors (25+). Donors of healthy breast tissue are motivated by survivor connections and the ability to help by donating. Their concerns and experiences are relatively positive and consistent with undergoing a minor surgical procedure. Younger donors have more concerns and negative experiences. Findings from this study can inform recruitment campaigns and donation procedures for banking of healthy tissue. ©2014 American Association for Cancer Research.
