Experimental methods for studying microbial survival in extraterrestrial environments.

PubMed

Olsson-Francis, Karen; Cockell, Charles S

2010-01-01

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.

Sterile Neutrino Searches in MiniBooNE and MicroBooNE

DOE Office of Scientific and Technical Information (OSTI.GOV)

Ignarra, Christina M.

Tension among recent short baseline neutrino experiments has pointed toward the possible need for the addition of one or more sterile (non-interacting) neutrino states into the existing neutrino oscillation framework. This thesis fi rst presents the motivation for sterile neutrino models by describing the short-baseline anomalies that can be addressed with them. This is followed by a discussion of the phenomenology of these models. The MiniBooNE experiment and results are then described in detail, particularly the most recent antineutrino analysis. This will be followed by a discussion of global fits to world data, including the anomalous data sets. Lastly, futuremore » experiments will be addressed, especially focusing on the MicroBooNE experiment and light collection studies. In particular, understanding the degradation source of TPB, designing the TPB-coated plates for MicroBooNE and developing lightguide collection systems will be discussed. We find an excess of events in the MiniBooNE antineutrino mode results consistent with the LSND anomaly, but one that has a di fferent energy dependence than the low-energy excess reported in neutrino mode. This disagreement creates tension within global fi ts which include up to three sterile neutrinos. The low-energy excess will be addressed by the MicroBooNE experiment, which is expected to start taking data in early 2015. Tension among existing experiments calls for additional, more decisive future experiments.« less

de Melo, Lucas Pereira; Stofel, Natália Sevilha; Gualda, Dulce Maria Rosa; de Campos, Edemilson Antunes

2014-09-01

To reflect on the experiences of nurses performing ethnographic fieldwork in three studies. The application of ethnography to nursing research requires discussion about nurses' experiences of ethnographic fieldwork. This article examines some of the dilemmas that arise during the research process. Three ethnographic studies conducted by the authors in the south and southeast of Brazil. Excerpts from field diaries created during each research are presented at the end of each topic discussed. This is a reflexive paper that explores the nurses' experience in ethnographic fieldwork. This article discusses the main tasks involved in ethnographic research, including defining the study aim, reading and understanding anthropological theoretical bases, and setting a timeframe for the study. The article also discusses the idiosyncrasies of the cultural contexts studied, the bureaucracy that may be confronted when gaining access to the field, the difficulty of transforming the familiar into the strange, why ethnocentric perspectives should be avoided, and the anthropological doubt that places the ethnographer in the position of apprentice. It also discusses the importance of listening to others, reflexivity and strategies to stay in the field. For researchers, ethnographic fieldwork can be a rite of passage, but one that provides invaluable experiences that emphasise the value of relationships based on dialogue, reflexivity and negotiation. The main tasks undertaken in ethnographic research discussed in this article could contribute to the nurse' experience of conducting ethnographic fieldwork.

2015-03-06

More than 90,000 patients with ESRD die annually in the United States, yet advance care planning (ACP) is underutilized. Understanding patients' and families' diverse needs can strengthen systematic efforts to improve ACP. In-depth interviews were conducted with a purposive sample of patients and family/friends from dialysis units at two study sites. Applying grounded theory, interviews were audiotaped, professionally transcribed, and analyzed in an iterative process. Emergent themes were identified, discussed, and organized into major themes and subthemes. Thirteen patients and nine family/friends participated in interviews. The mean patient age was 63 years (SD 14) and five patients were women. Participants identified as black (n=1), Hispanic (n=4), Native American (n=4), Pacific Islander (n=1), white (n=11), and mixed (n=1). Three major themes with associated subthemes were identified. The first theme, "Prior experiences with ACP," revealed that these discussions rarely occur, yet most patients desire them. A potential role for the primary care physician was broached. The second theme, "Factors that may affect perspectives on ACP," included a desire for more of a connection with the nephrologist, positive and negative experiences with the dialysis team, disenfranchisement, life experiences, personality traits, patient-family/friend relationships, and power differentials. The third theme, "Recommendations for discussing ACP," included thoughts on who should lead discussions, where and when discussions should take place, what should be discussed and how. Many participants desired better communication with their nephrologist and/or their dialysis team. A number expressed feelings of disenfranchisement that could negatively impact ACP discussions through diminished trust. Life experiences, personality traits, and relationships with family and friends may affect patient perspectives regarding ACP. This study's findings may inform clinical practice and will be useful in designing prospective intervention studies to improve patient and family experiences at the end of life.

Participant supervision: supervisor and supervisee experiences of cotherapy.

PubMed

Falke, Stephanie I; Lawson, Lindsey; Pandit, Mayuri L; Patrick, Elizabeth A

2015-04-01

Participant supervision is a unique application of live supervision in which a supervisor and supervisee see clients conjointly. Although minimally discussed in the family therapy literature, it has notable advantages, chief among them being a shared clinical experience that increases attunement to supervisee skill and development, the modeling of skillful intervention, and a higher degree of collegiality. However, it is not without its challenges, including supervisee vulnerability and anxiety, diffusion of responsibility, and limited time for case discussion. This article highlights the experience of one supervisor and three doctoral-level supervisees engaging in participant supervision over the course of a 2-year period. Using illustrative examples, we discuss our experience of the advantages and challenges of participant supervision, and provide recommendations for establishing a collaborative relational context within which supervisory benefits can be maximized. © 2013 American Association for Marriage and Family Therapy.

The effects of individual- and network-level factors on discussion of cancer experiences: Survivors of childhood cancer in Korea.

PubMed

Kim, Min Ah; Yi, Jaehee; Prince, Kort C; Nagelhout, Elizabeth; Wu, Yelena P

2018-01-01

This study aimed to identify young adult Korean cancer survivors' individual- (psychological distress, stigma, sociodemographic variables, and cancer-related variables) and network-level factors (relationship type, social support type) that influence discussion of their cancer experiences. Sixty-eight survivors of childhood cancer who were recruited using snowball sampling nominated 245 individuals from their networks, including family and intimate partners (40%) and friends and acquaintances (60%), as people with whom they most frequently interacted. Results of multilevel modeling analysis indicated that higher levels of internalized shame were a prominent individual-level factor associated with a lack of discussion of cancer experiences. Relationship type and support type at the network-level were also significant correlates of discussion of cancer experiences. Programs for reducing the survivors' shame, improving illness identity, and providing professional training for building social relationships that are intimate and in which they could exchange reciprocal support may help Korean childhood cancer survivors to openly share their cancer experiences with others in their social network and to be successful in the journey of cancer survivorship.

From problem people to addictive products: a qualitative study on rethinking gambling policy from the perspective of lived experience.

PubMed

Miller, Helen E; Thomas, Samantha L; Robinson, Priscilla

2018-04-06

Previous research has shown that government and industry discussions of gambling may focus on personal responsibility for gambling harm. In Australia, these discussions have largely excluded people with lived experience of problem gambling, including those involved in peer support and advocacy. We conducted 26 in-depth interviews with people with current or previous problem gambling on electronic gaming machines (EGMs) involved in peer support and advocacy activities, using an approach informed by Interpretive Policy Analysis and Constructivist Grounded Theory. Participants perceived that government and industry discussed gambling as safe and entertaining with a focus on personal responsibility for problem gambling. This focus on personal responsibility was perceived to increase stigma associated with problem gambling. In contrast, they described gambling as risky, addictive and harmful, with problem gambling resulting from the design of EGMs. As a result of their different perspectives, participants proposed different interventions to reduce gambling harm, including reducing accessibility and making products safer. Challenging the discourses used by governments and industry to describe gambling, using the lived experience of people with experience of gambling harm, may result in reduced stigma associated with problem gambling, and more effective public policy approaches to reducing harm.

PubMed

Chapman, Phillip L; Seidel, George E

2008-01-01

The present paper concerns statistical issues in the design of animal reproduction experiments, with emphasis on the problems of sample size determination and power calculations. We include examples and non-technical discussions aimed at helping researchers avoid serious errors that may invalidate or seriously impair the validity of conclusions from experiments. Screen shots from interactive power calculation programs and basic SAS power calculation programs are presented to aid in understanding statistical power and computing power in some common experimental situations. Practical issues that are common to most statistical design problems are briefly discussed. These include one-sided hypothesis tests, power level criteria, equality of within-group variances, transformations of response variables to achieve variance equality, optimal specification of treatment group sizes, 'post hoc' power analysis and arguments for the increased use of confidence intervals in place of hypothesis tests.

The problem of creating habits: establishing health-protective dental behaviors.

PubMed

McCaul, K D; Glasgow, R E; O'Neill, H K

1992-01-01

We describe three experiments testing treatments to promote the performance of health-protective dental behaviors. Subjects included 55 women from an introductory psychology course (Experiment 1), 45 men and women (Experiment 2), and 81 older-than-average students identified as at risk for gum disease (Experiment 3). The interventions, derived from social cognitive theory, included health education, skills training, and self-monitoring. In each study, we examined the contribution of additional treatment components, including social support (Experiment 1), intensive contact (Experiment 2), and flexible goal setting (Experiment 3). Across experiments, the behavioral results were remarkably similar: Subjects exhibited excellent adherence while in the study but, at follow-up, reported behavior that differed little from baseline. We discuss parallels between attempts to promote health-protective dental behaviors and other health-promotion programs, and we describe different perspectives from which to address the problem of creating healthy habits.

PubMed

Rutter, Michael

2016-11-01

Translational research focuses on innovation in healthcare settings, but this is a two-way process that may have implications for either treatment or prevention. Smoking and lung cancer and the fetal alcohol syndrome are used as examples. Experimental medicine that budges basic and clinical science often constitutes a key way forward. Areas of scientific progress and challenge are discussed in relation to drug action, social cognition, cognitive neuroscience, molecular genetics, gene-environment interaction, and epigenetics. Key concepts and challenges in relation to stress include toxicity, allostatic load, the hypothalamus-pituitary-adrenal axis, and objectives versus subjective stress. The reasons for the need to test causal inferences are discussed. Various kinds of "natural experiments" are discussed in illustration using the assisted conception design, the discordant monozygotic twin design, and the study of universal exposure. Animal models are discussed in relation to enrichment and deprivation effects and the effects of infant separation experiences, epigenetic effects, and the biological embedding of experiences. Translational issues are discussed in relation to the hypothalamic-pituitary-adrenal axis, epigenetics, and inflammation. In conclusion, it is suggested that there are immediate possibilities for experimental medicine but caution is needed with respect to moving into translation too quickly.

García-Mangas, José Alberto; Viniegra-Velázquez, Leonardo

2008-01-01

The teachers' formation program at IMSS includes the methodological diplomate in teaching level I (DMDI) and level II (DMDII). This program is based in educational strategies that promote the participation (guide towards knowledge elaboration). The importance of discussion in small groups (subgroups) to increase learning has been showed as part of such strategies. To evaluate the influence in learning of the professors' experience in coordinating the subgroup discussion. Three groups of students were included (professors in teaching formation) that had consecutively studied the DMDI: DMDIa, DMDIb, and DMDIc. There was also included a group of DMDII whose students had participated in DMDI as coordinators of the subgroup discussion of DMDIb and DMDIc (DMDIa did not count with coordinators). Two instruments previously validated were used to evaluate the development of a position about education and scientific work (indicator of both: % of consequence). Evaluations were made at the beginning and end of each DMDI. Position in education: at the beginning DMDIa = 36; DMDIb = 30, DMDIc = 31, without differences among them (p 0.65). After the interventions the increases were: DMDIa from 36 to 75 (p < 0.01), DMDIb from 30 to 91 (p < 0.01), DMDIc from 31 to 90 (p < 0.01). When comparing the groups among themselves, differences were found between DMDIa and DMDIb, DMDIa and DMDIc, and no differences were found between DMDIb and DMDIc. Position about scientific work: at the beginning DMDIa = 20; DMDIb = 14; DMDIc = 15 (p. 0.35). After the interventions the increases were: DMDIa from 20 to 35 (p < 0.05); DMDIb from 14 to 53 (p < 0.02), DMDIc from 15 to 79 (p < 0.001). When comparing the groups among themselves, difference was found between DMDIb and DMDIc (p < 0.02) and from these two and DMDIa. The results support the hypothesis that the professor's experience in the coordination of subgroup discussion has a notorious influence in learning. The DMDIa group that did not have this support showed lower advances with both instruments. The DMDIb group that had coordinating professors with little experience had equivalent advances to DMDIc in position about education, and lower advances in the position about scientific work. The DMDIc group whose coordinating professors had a previous experience with the DMDIb group showed the greatest increases. Features of educational strategy promoting the participation are described as well as the importance of the experience of the professor in coordinating the discussion, to increase learning.

Using co-teaching as a means of facilitating interprofessional collaboration in health and social care.

PubMed

Crow, Jayne; Smith, Lesley

2003-02-01

In this paper we report the findings of a collaborative enquiry on our experience as tutors co-teaching interprofessional collaboration to a multidisciplinary group of undergraduates. We have different professional/academic backgrounds and the student group included health and social work professionals alongside a number of non-professionals. Our data included our perceptions of the co-teaching experience collected by means of our reflective diaries and reflective conversations during planning and after teaching sessions. We also collected data on student perceptions elicited by means of student evaluations and a student focus group discussion. The data illuminate the process of using co-teaching to role model shared learning and collaborative working within the classroom and highlight the importance of carefully planning co-teaching interaction, including the use of humour, tension, different knowledge bases and styles of debate. The deliberate use of the interactions made possible by coteaching enabled us to create an active learning environment that facilitated the teaching of collaboration. Drawing on our experience, we discuss the considerable potential of using co-teaching to role model collaborative working for multidisciplinary student groups.

Examining Theory-Based Behavior-Change Constructs, Social Interaction, and Sociability Features of the Weight Watchers' Online Community.

PubMed

Wang, Ye; Willis, Erin

2016-12-01

Objective To examine whether and to what extent relevant and meaningful discussions of weight loss occurred in the Weight Watchers' online community, and whether and to what extent the online community is designed for fostering such discussions. A multimethod approach was used here. First, a quantitative content analysis was conducted on 320 posts from 64 threads sampled from WeightWatchers.com's message boards between December 1, 2011, and January 31, 2012. The coding categories included constructs from the health belief model, the planned behavior theory, and the theory of self-efficacy. An acceptable level of intercoder reliability was reached; frequencies, cluster analysis, and t test were reported. Second, a conventional content analysis of the posts was conducted. The posts were examined for themes and patterns within the discussion. Finally, the researchers examined the sociability features of the message boards. The qualitative review followed established procedures and was conducted independently by four researchers. Mastery experience occurred in 46% of the posts. Threads focusing on physical activities contained more perceived barriers, mastery experiences, and verbal persuasion than other types of threads. Posts focusing on diet included unanswered questions about dieting practices with certain medical conditions. Posts focusing on mastery experience celebrated any small step toward success. Posts irrelevant to weight loss mostly contained events and happenings in members' lives. The sociability review revealed a lack of moderation. The Weight Watchers' online community included much discussion about weight loss. Findings suggest that physical activities require more encouragement than dieting. Health educators have an opportunity to interject and moderate meaningful discussions. For example, dieting with certain medical conditions, opinions on various diets, and the relationship between dieting and being healthy are opportunities to facilitate learning. Discussion posts irrelevant to weight loss help build social relationships. © 2016 Society for Public Health Education.

Space Shuttle Program (SSP) Shock Test and Specification Experience for Reusable Flight Hardware Equipment

Larsen, Curtis E.

2012-01-01

As commercial companies are nearing a preliminary design review level of design maturity, several companies are identifying the process for qualifying their multi-use electrical and mechanical components for various shock environments, including pyrotechnic, mortar firing, and water impact. The experience in quantifying the environments consists primarily of recommendations from Military Standard-1540, Product Verification Requirement for Launch, Upper Stage, and Space Vehicles. Therefore, the NASA Engineering and Safety Center (NESC) formed a team of NASA shock experts to share the NASA experience with qualifying hardware for the Space Shuttle Program (SSP) and other applicable programs and projects. Several team teleconferences were held to discuss past experience and to share ideas of possible methods for qualifying components for multiple missions. This document contains the information compiled from the discussions

PubMed

Corona, Rosalie; Yaros, Anna; Pope, Michell; Velazquez, Efren; Augustin, Divinda

2016-01-01

Parents play a critical role in shaping their children's substance use behaviors, yet few studies have examined the messages that caregivers give their adolescents about tobacco. In this study, we identify tobacco-related messages discussed by African American maternal caregivers and their adolescent daughters. Twenty-five African American maternal caregivers and their adolescent daughters participated in a video-taped discussion about tobacco. Discussions were transcribed and coded thematically. Seven themes emerged, which were grouped into tobacco-messages and communication strategies. Messages included health risks, non-health-related reasons to stop smoking, reasons people smoke, and tobacco products and marijuana. Strategies caregivers used to communicate their tobacco-related messages included sharing personal or their families' experience with smoking, using humor, and role-playing. Finally, embedded within all of the themes, participants expressed their disapproval of tobacco use, whether it was directed at their own use, their adolescents' use, a family members' use, or peers' use. African American maternal caregivers and their daughters openly talk about a variety of tobacco-related topics, and caregivers are open to sharing their own and their families' experience with substance use. Findings also suggest that having caregivers and their adolescents participate in discussions tasks could be potentially beneficial in facilitating discussions and could identify areas in which caregivers could use help in discussing sensitive topics.

Lab- and space-based researchers discuss plasma experiments

NASA Astrophysics Data System (ADS)

Baker, D. N.; Yamada, M.

Plasma physics provides a common language and set of approaches that tie together all scientists who study the acceleration, transport, and loss processes of the plasma state. Some years ago, researchers from the laboratory and space research communities suggested a workshop to bring together the diverse researchers in the respective fields. A series of workshops on the “Interrelationship between Plasma Experiments in the Laboratory and Space” (IPELS) was established, and the third meeting was held July 24-28, 1995, in the beautiful and historic town of Pitlochry in the Scottish Highlands.The conference reestablished the critical point that plasma physics is an important but surprisingly diversified research discipline. Meetings attendees discussed a number of new approaches to plasma research, including novel diagnostic techniques for use in space, such as active antennas and electric field sounding devices. Detailed discussions covered spacecraft-plasma environment interactions, including vehicle charging and neutral gas release; fundamental aspects of industrial application of dusty plasmas and waves in dusty plasmas; a very distinctive phase transition of coulomb crystals (from solid state to liquid state) in dusty plasmas; and terrella experiments to simulate and study chaotic transport in the ionosphere.

2001-01-01

This systems report describes how the Optical Properties Monitor (OPM) experiment was developed. Pertinent design parameters are discussed, along with mission information and system requirements to successfully complete the mission. Environmental testing was performed on the OPM to certify it for spaceflight. This testing included vibration, thermal vacuum, electromagnetic interference and conductance, and toxicity tests. Instrument and monitor subsystem performances, including the reflectometer, vacuum ultraviolet, total integrated scatter, atomic oxygen monitor, irradiance monitor, and molecular contamination monitor during the mission are discussed. The OPM experiment was launched aboard the Space Shuttle on mission STS-81 in January 1997 and transferred to the Mir space station. An extravehicular activity (EVA) was performed in April 1997 to attach the OPM experiment to the outside of the Mir/Shuttle Docking Module for space environment exposure. The OPM conducted in situ measurements of a number of material samples. These data may be found in the OPM Science Report. OPM was retrieved during an EVA in January 1998 and was returned to Earth on board the Space Shuttle on mission STS-89.

Maas, Lillian; Ezeobele, I Ezebuiro; Tetteroo, Marieke

2012-07-01

The purpose of this article is to discuss the challenges and rewards of developing and nurturing an international clinical psychiatric mental health advanced nursing practice exchange between the Netherlands and the United States. Since 1997, Rotterdam University of Applied Sciences in the Netherlands has been participating in international clinical experiences for their psychiatric mental health (PMH) advanced practice nursing students. The international experience is mandatory prior to graduation and is the first of its kind in Europe to mandate such a unique experience. This study sample included eight Dutch PMH advanced practice nursing students enrolled in a full-time master's in advanced nursing practice program. The descriptive study included reflective reports and one-on-one discussions over a 3-year period. With proper planning, an international nursing experience provides a unique opportunity for nurses to think beyond their own culture and healthcare system. Solving problems together through different perspectives creates opportunities for creative solutions. International partnerships within PMH advanced practice nursing promotes sharing of knowledge and solutions as patients and diseases have no border. © 2011 Wiley Periodicals, Inc.

Autonomy and dependence: a discussion paper on decision-making in teenagers and young adults undergoing cancer treatment.

PubMed

Davies, Jane; Kelly, Daniel; Hannigan, Ben

2015-09-01

A discussion which aims to explore the diversity of decision-making during teenage and young adult cancer treatment. The discussion will be related to the concepts of autonomy, dependence and decision-making in this age group. The experience of cancer involves a significant series of treatment decisions. However, other non-treatment decisions also have to be made which can relate to any aspect of everyday life. These decisions occur against the backdrop of young people's disease experience. Discussion paper. A literature search for the period 1990-2013 was undertaken. This included searching the following databases: Cumulative Index for Nursing and Allied Health Literature (CINAHL), SCOPUS, Medline, DARE, Applied Social Sciences Index and Abstracts (ASSIA), (Psych Info) and The Cochrane Library. There is a lack of evidence into the experience of everyday decisions made by young people during cancer treatment. This may affect them in the form of unmet needs that nurses, or other professionals, fail to appreciate. Further exploration of how teenagers and young adults experience the range and process of decision-making during cancer treatment could be useful in helping to provide effective supportive care for this age group. © 2015 John Wiley & Sons Ltd.

Ionizing radiation exposure of LDEF (pre-recovery estimates)

Benton, E. V.; Heinrich, W.; Parnell, T. A.; Armstrong, T. W.; Derrickson, J. H.; Fishman, G. J.; Frank, A. L.; Watts, J. W. Jr; Wiegel, B.

1992-01-01

The long duration exposure facility (LDEF), launched into a 258 nautical mile orbit with an inclination of 28.5 degrees, remained in space for nearly 6 yr. The 21,500 lb NASA satellite was one of the largest payloads ever deployed by the Space Shuttle. LDEF completed 32,422 orbits and carried 57 major experiments representing more than 200 investigators from 33 private companies, 21 universities and nine countries. The experiments covered a wide range of disciplines including basic science, electronics, optics, materials, structures and power and propulsion. A number of the experiments were specifically designed to measure the radiation environment. These experiments are of specific interest, since the LDEF orbit is essentially the same as that of the Space Station Freedom. Consequently, the radiation measurements on LDEF will play a significant role in the design of radiation shielding of the space station. The contributions of the various authors presented here attempt to predict the major aspects of the radiation exposure received by the various LDEF experiments and therefore should be helpful to investigators who are in the process of analyzing experiments which may have been affected by exposure to ionizing radiation. The paper discusses the various types and sources of ionizing radiation including cosmic rays, trapped particles (both protons and electrons) and secondary particles (including neutrons, spallation products and high-LET recoils), as well as doses and LET spectra as a function of shielding. Projections of the induced radioactivity of LDEF are also discussed.

Relationships and Betrayal among Young Women: Theoretical Perspectives on Adolescent Dating Abuse

Burton, Candace W.; Halpern-Felsher, Bonnie; Rankin, Sally H.; Rehm, Roberta S.; Humphreys, Janice C.

2010-01-01

AIMS Adolescent dating abuse is not specifically described by any current nursing theory, and this paper presents discussion of some existing theories that could inform a nursing theory of adolescent dating abuse. To account for the effects of gender, this discussion is limited to young women. BACKGROUND Adolescent dating abuse is an important and understudied international issue for nursing. Theoretical frameworks can support development of nursing scholarship for such issues. No single theory yet exists within nursing to explain the experiences and health ramifications of dating abuse among young women. DATA SOURCES A summary table of theories is provided. Literature was gathered via database search and bibliographic snowballing from reference lists of relevant articles. Included literature dates from 1982 through 2010. DISCUSSION Theories of relationship formation and function are discussed, including attachment, investment, feminist and gender role conflict theories. Betrayal trauma theory is considered as a mechanism of injury following an abusive dating experience. IMPLICATIONS FOR NURSING Gender, relationship, and adolescence combine in a complex developmental moment for young women. To improve nursing care for those at risk for or in the throes of abusive relationships, it is critical to develop specific nursing approaches to understanding these relationships. CONCLUSION Existing theories related to relationship and traumatic experiences can be combined in the development of a nursing theory of adolescent dating abuse among young women. PMID:21261691

The Cryogenic Test Bed experiments: Cryogenic heat pipe flight experiment CRYOHP (STS-53). Cryogenic two phase flight experiment CRYOTP (STS-62). Cryogenic flexible diode flight experiment CRYOFD

NASA Astrophysics Data System (ADS)

Thienel, Lee; Stouffer, Chuck

1995-09-01

This paper presents an overview of the Cryogenic Test Bed (CTB) experiments including experiment results, integration techniques used, and lessons learned during integration, test and flight phases of the Cryogenic Heat Pipe Flight Experiment (STS-53) and the Cryogenic Two Phase Flight Experiment (OAST-2, STS-62). We will also discuss the Cryogenic Flexible Diode Heat Pipe (CRYOFD) experiment which will fly in the 1996/97 time frame and the fourth flight of the CTB which will fly in the 1997/98 time frame. The two missions tested two oxygen axially grooved heat pipes, a nitrogen fibrous wick heat pipe and a 2-methylpentane phase change material thermal storage unit. Techniques were found for solving problems with vibration from the cryo-collers transmitted through the compressors and the cold heads, and mounting the heat pipe without introducing parasitic heat leaks. A thermally conductive interface material was selected that would meet the requirements and perform over the temperature range of 55 to 300 K. Problems are discussed with the bi-metallic thermostats used for heater circuit protection and the S-Glass suspension straps originally used to secure the BETSU PCM in the CRYOTP mission. Flight results will be compared to 1-g test results and differences will be discussed.

Self-reported experiences of discrimination and health: scientific advances, ongoing controversies, and emerging issues.

PubMed

Lewis, Tené T; Cogburn, Courtney D; Williams, David R

2015-01-01

Over the past two decades, research examining the impact of self-reported experiences of discrimination on mental and physical health has increased dramatically. Studies have found consistent associations between exposure to discrimination and a wide range of Diagnostic and Statistical Manual of Mental Disorders (DSM)-diagnosed mental disorders as well as objective physical health outcomes. Associations are seen in cross-sectional as well as longitudinal studies and persist even after adjustment for confounding variables, including personality characteristics and other threats to validity. However, controversies remain, particularly around the best approach to measuring experiences of discrimination, the significance of racial/ethnic discrimination versus overall mistreatment, the need to account for "intersectionalities," and the importance of comprehensive assessments. These issues are discussed in detail, along with emerging areas of emphasis including cyber discrimination, anticipatory stress or vigilance around discrimination, and interventions with potential to reduce the negative effects of discrimination on health. We also discuss priorities for future research and implications for interventions and policy.

Beresford, B; Stuttard, L

2014-08-01

Awareness is growing that young adults may have distinctive experiences of adult healthcare and that their needs may differ from those of other adult users. In addition, the role of adult health teams in supporting positive transitions from paediatrics is increasingly under discussion. This paper contributes to these debates. It reports a qualitative study of the experiences of young adults - all with complex chronic health conditions - as users of adult health services. Key findings from the study are reported, including an exploration of factors that help to explain interviewees' experiences. Study findings are discussed in the context of existing evidence from young adults in adult healthcare settings and theories of 'young adulthood'. Implications for training and practice are considered, and priorities for future research are identified. © 2014 Royal College of Physicians.

Genetic Counselors' Experiences Regarding Communication of Reproductive Risks with Autosomal Recessive Conditions found on Cancer Panels.

PubMed

Mets, Sarah; Tryon, Rebecca; Veach, Patricia McCarthy; Zierhut, Heather A

2016-04-01

The development of hereditary cancer genetic testing panels has altered genetic counseling practice. Mutations within certain genes on cancer panels pose not only a cancer risk, but also a reproductive risk for autosomal recessive conditions such as Fanconi anemia, constitutional mismatch repair deficiency syndrome, and ataxia telangiectasia. This study aimed to determine if genetic counselors discuss reproductive risks for autosomal recessive conditions associated with genes included on cancer panels, and if so, under what circumstances these risks are discussed. An on-line survey was emailed through the NSGC list-serv. The survey assessed 189 cancer genetic counselors' experiences discussing reproductive risks with patients at risk to carry a mutation or variant of uncertain significance (VUS) in a gene associated with both an autosomal dominant cancer risk and an autosomal recessive syndrome. Over half (n = 82, 55 %) reported having discussed reproductive risks; the remainder (n = 66, 45 %) had not. Genetic counselors who reported discussing reproductive risks primarily did so when patients had a positive result and were of reproductive age. Reasons for not discussing these risks included when a patient had completed childbearing or when a VUS was identified. Most counselors discussed reproductive risk after obtaining results and not during the informed consent process. There is inconsistency as to if and when the discussion of reproductive risks is taking place. The wide variation in responses suggests a need to develop professional guidelines for when and how discussions of reproductive risk for autosomal recessive conditions identified through cancer panels should occur with patients.

Unravelling current sexual care in chronic kidney disease: perspective of social workers.

Fifty to eighty percent of patients suffering from chronic kidney disease (CKD) experience a form of sexual dysfunction (SD), even after renal transplantation. Despite this, inquiring about SD is often not included in the daily practice of renal care providers. This paper explores the perspectives of renal social workers regarding sexual care for patients and evaluates their practice, attitude towards responsibility and knowledge of SD. A cross-sectional study was conducted using a 41-item online survey. Seventy-nine members of the Dutch Federation of Social Workers Nephrology. It was revealed that 60% of respondents discussed SD with a fifth of their patients. Frequency of discussion was associated with experience (p = 0.049), knowledge (p = 0.001), supplementary education (p = 0.006), and the availability of protocols on sexual care (p = 0.007). Main barriers towards discussing SD consisted of 'culture and religion' (51.9%), 'language and ethnicity' (49.4%), and 'presence of a third person' (45.6%). Sufficient knowledge of SD was present in 28% of respondents. The responsibility for discussion was 96% nephrologists and 81% social workers. This study provides evidence that a part of Dutch nephrology social workers do not provide sexual care regularly, due to insufficient experience and sexual knowledge, absence of privacy and protocols and barriers based on cultural diversity. According to the respondents the responsibility for this aspect of care should be multidisciplinary.

Medical Education to Enhance Critical Consciousness: Facilitators' Experiences.

PubMed

Zaidi, Zareen; Vyas, Rashmi; Verstegen, Danielle; Morahan, Page; Dornan, Tim

2017-11-01

To analyze educators' experiences of facilitating cultural discussions in two global health professions education programs and what these experiences had taught them about critical consciousness. A multicultural research team conducted in-depth interviews with 16 faculty who had extensive experience facilitating cultural discussions. They analyzed transcripts of the interviews thematically, drawing sensitizing insights from Gramsci's theory of cultural hegemony. Collaboration and conversation helped the team self-consciously examine their positions toward the data set and be critically reflexive. Participant faculty used their prior experience facilitating cultural discussions to create a "safe space" in which learners could develop critical consciousness. During multicultural interactions they recognized and explicitly addressed issues related to power differentials, racism, implicit bias, and gender bias. They noted the need to be "facile in attending to pain" as learners brought up traumatic experiences and other sensitive issues including racism and the impact of power dynamics. They built relationships with learners by juxtaposing and exploring the sometimes-conflicting norms of different cultures. Participants were reflective about their own understanding and tendency to be biased. They aimed to break free of such biases while role modeling how to have the courage to speak up. Experience had given facilitators in multicultural programs an understanding of their responsibility to promote critical consciousness and social justice. How faculty without prior experience or expertise could develop those values and skills is a topic for future research.

Lutchyn, R. M.; Bakkers, E. P. A. M.; Kouwenhoven, L. P.; Krogstrup, P.; Marcus, C. M.; Oreg, Y.

2018-05-01

Realizing topological superconductivity and Majorana zero modes in the laboratory is a major goal in condensed-matter physics. In this Review, we survey the current status of this rapidly developing field, focusing on proposals for the realization of topological superconductivity in semiconductor-superconductor heterostructures. We examine materials science progress in growing InAs and InSb semiconductor nanowires and characterizing these systems. We then discuss the observation of robust signatures of Majorana zero modes in recent experiments, paying particular attention to zero-bias tunnelling conduction measurements and Coulomb blockade experiments. We also outline several next-generation experiments probing exotic properties of Majorana zero modes, including fusion rules and non-Abelian exchange statistics. Finally, we discuss prospects for implementing Majorana-based topological quantum computation.

Simulation of Physical Experiments in Immersive Virtual Environments

NASA Technical Reports Server (NTRS)

Noor, Ahmed K.; Wasfy, Tamer M.

2001-01-01

An object-oriented event-driven immersive Virtual environment is described for the creation of virtual labs (VLs) for simulating physical experiments. Discussion focuses on a number of aspects of the VLs, including interface devices, software objects, and various applications. The VLs interface with output devices, including immersive stereoscopic screed(s) and stereo speakers; and a variety of input devices, including body tracking (head and hands), haptic gloves, wand, joystick, mouse, microphone, and keyboard. The VL incorporates the following types of primitive software objects: interface objects, support objects, geometric entities, and finite elements. Each object encapsulates a set of properties, methods, and events that define its behavior, appearance, and functions. A container object allows grouping of several objects. Applications of the VLs include viewing the results of the physical experiment, viewing a computer simulation of the physical experiment, simulation of the experiments procedure, computational steering, and remote control of the physical experiment. In addition, the VL can be used as a risk-free (safe) environment for training. The implementation of virtual structures testing machines, virtual wind tunnels, and a virtual acoustic testing facility is described.

Experience-based Learning in Acadia National Park: a Successful, Long-running, Model Field Course

NASA Astrophysics Data System (ADS)

Connaughton, M.

2015-12-01

This two-week field course has been offered alternate summers since 2000 in Acadia National Park on Mount Desert Island, Maine and addresses the geological history, physical and biological oceanography and principles of community ecology applicable to terrestrial and/or marine communities of coastal Maine. The course is often transformative and deeply meaningful to the students, many of whom have limited travel experience. The essential components of experience-based learning are well represented in this class with multiple opportunities for abstract conceptualization, active experimentation, concrete hands-on experiences and reflective observation built into the course. Each day begins with a lecture introducing concepts, which are then made concrete though daily field trips (4-8 hours in duration) into the park that include rigorous hiking, some kayaking and one commercial nature cruise. Field trips include hands-on experience with lecture concepts, on-site lessons in field methods, and data collection for independent projects. Each field trip is tied to a specific independent project, which are generated by the instructor, but self-selected by the students. Every student is actively involved in data collection during each field trip, with one student in charge of the collection each day. Daily guided journaling in three parts (scientific, personal and creative) and evening discussions provide ample opportunity for the student to reflect on the scientific content of the course, examine their personal reactions to what they have experienced and to be creative, sharing prior experiences, prior learning and their personalities. The course includes two exams, each following a week of lecture and field experiences. Independent research projects include the production of a manuscript-formatted report complete with statistical analysis of the data and a literature-based discussion of the conclusions. The combination of experiential reinforcement of concepts, abundant opportunity for written and spoken reflection, the beauty of the setting, the challenges of working in the field and the resultant bonding of the students and instructors provide a highly effective and unforgettable learning experience.

Neutrino Oscillations: Eighty Years in Review

NASA Astrophysics Data System (ADS)

Bowers, Rebecca Lyn

In order to discuss neutrino oscillations, it is necessary to have knowledge of the developments in the field spanning the last eighty years. The existence of the neutrino was posited by Wolfgang Pauli in 1930 to account for the mass defect in beta decay, and to this day physicists are still endeavoring to answer fundamental questions about this enigmatic particle. The scope of this thesis includes a historical background of neutrino physics and a discussion of neutrinos and the Standard Model; subsequent to this is a discussion of the Solar Neutrino Problem, which provided the impetus for the proposal of neutrino oscillations. Bolstering the theory of neutrino oscillations (which is developed in the body of this thesis) are neutrino detector experiments and their results; these include the Homestake experiment, SNO, Kamiokande and Super-Kamiokande, MINOS, and Double-Chooz. We also include relevant derivations, most particularly of the quantum mechanics of neutrino oscillations as treated in the wave packet formalism. We have amassed here the principle theories and experimental results -- a mere tip of the iceberg -- that have brought us to our current understanding of neutrino oscillations. We have also studied the quantum mechanics of neutrino oscillations and developed for ourselves the wave packet formalism describing the phenomenon.

Solar array module plasma interactions experiment (SAMPIE) - Science and technology objectives

NASA Technical Reports Server (NTRS)

Hillard, G. B.; Ferguson, Dale C.

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.

Workshop on active learning: two examples

NASA Astrophysics Data System (ADS)

Ben Lakhdar, Zohra; Lahmar, Souad; Lakshminarayanan, Vasudevan

2014-07-01

Optics is an enabling science that has far ranging importance in many diverse fields. However, many students do not find it to be of great interest. A solution to this problem is to train teachers in active learning methodologies so that the subject matter can be presented to generate student interest. We describe a workshop to present an example of an active learning process in Optics developed for training of teachers in developing countries (a UNESCO project) and will focus on 2 two different activities: 1. Interference and diffraction is considered by students as being very hard to understand and is taught in most developing countries as purely theoretical with almost no experiments. Simple experiments to enhance the conceptual understanding of these wave phenomena will be presented and 2. Image formation by the eye. Here we will discuss myopia, hyperopia and astigmatism as well as accommodation. In this module we will discuss image. The objective of the workshop will be to provide an experience of the use of the active learning method in optics including the use of experiments, mind's on and hands-on exercises, group and class discussions

Jervaeus, Anna; Nilsson, Jenny; Eriksson, Lars E; Lampic, Claudia; Widmark, Catarina; Wettergren, Lena

2016-02-01

To explore childhood cancer survivors' views about sex and sexual experiences and, as an additional aim, their possible needs for care and support from health care professionals regarding sexual life. Written online focus group discussions were performed with survivors of childhood cancer, identified through the Swedish Childhood Cancer Registry; 133 (36%; aged 16-25) participated. Written text was analysed using qualitative content analysis. The analysis resulted in one main category: Could my cancer experience have an impact on my sexual life? with four generic categories: Sex considered to be good, Feeling insecure and falling behind, Relating sex to a stable relationship and Concerns related to the physical body. In general, participants had not reflected on the possibility that their cancer experience could impact on sexual life. Sex was often considered to be something natural, important and taken for granted. However, thoughts and worries were expressed including being shy, feeling insecure and falling behind peers. Physical concerns included vaginal dryness and difficulties related to erection and reaching orgasm. Many participants stated that sexual issues had not been discussed with health care professionals, however, the need for such support differed. Many of the childhood cancer survivors' did not relate their sexual experiences to previous cancer treatment. However, problems were expressed, both of emotional and physical nature. Many participants stated that they had not received any information or support regarding sexual issues from health care professionals, why it is recommended to be regularly addressed in follow-up care.

Metzger, Maureen; Song, Mi-Kyung; Devane-Johnson, Stephanie

2016-01-01

To describe LVAD patients' and surrogates' experiences with, and perspectives on SPIRIT-HF, an advance care planning (ACP) intervention. ACP is important for patients with LVAD, yet little is known about their experiences or those of their surrogates who have participated in ACP discussions. We used qualitative content analysis techniques to conduct a secondary analysis of 28 interviews with patients with LVAD (n = 14) and their surrogates (n = 14) who had participated in an RCT pilot study of SPIRIT-HF. Main themes from the data include: 1) sharing their HF stories was very beneficial; 2) participating in SPIRIT-HF led to greater peace of mind for patients and surrogates; 3) "one size does not fit all" when it comes to timing of ACP discussions. An understanding patient and surrogate perspectives may inform clinicians' approach to ACP discussions. Copyright © 2016 Elsevier Inc. All rights reserved.

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.

1992-01-01

Potential space missions of the nineties and the next century require that we look at the broad category of remote systems as an important means to achieve cost-effective operations, exploration and colonization objectives. This paper addresses such missions, which can use remote systems technology as the basis for identifying required capabilities which must be provided. The relationship of the space-based tasks to similar tasks required for terrestrial applications is discussed. The development status of the required technology is assessed and major issues which must be addressed to meet future requirements are identified. This includes the proper mix of humans and machines, from pure teleoperation to full autonomy; the degree of worksite compatibility for a robotic system; and the required design parameters, such as degrees-of-freedom. Methods for resolution are discussed including analysis, graphical simulation and the use of laboratory test beds. Grumman experience in the application of these techniques to a variety of design issues are presented utilizing the Telerobotics Development Laboratory which includes a 17-DOF robot system, a variety of sensing elements, Deneb/IRIS graphics workstations and control stations. The use of task/worksite mockups, remote system development test beds and graphical analysis are discussed with examples of typical results such as estimates of task times, task feasibility and resulting recommendations for design changes. The relationship of this experience and lessons-learned to future development of remote systems is also discussed.

Our communication activities included: our own field blog (www.arcticmethane.wordpress.com), which was syndicated to the Scientific American Expeditions blog; writing articles for other blogs with a wider audience than our own; use of twitter; and podcasting our field work. The grand finale to our communications work was a live event at a science festival, in which we took the audience along with us on a recreated research flight, complete with a life-size mock up of a section of our research aircraft. I will discuss my experiences of these forms of communication, and give an evaluation of their successes and failures.

Research exploring the needs of families of childhood cancer survivors is critical to improving the experiences of future families faced by this disease. However, there are numerous challenges in conducting research with this unique population, including a relatively high mortality rate. In recognition that research with cancer survivors is a relational activity, this article presents a series of cases of parents bereaved by childhood cancer who unintentionally received invitations to participate in survivorship research. We explore six ethical considerations, and compare our experiences with that described previously. Our considerations include the sharing of confidential information with external parties to confirm past patients' vital status and appropriate researcher responses to bereaved parents. The management of researchers' emotional safety when working with illness populations and the fact that study invitations can elicit grief responses in non-bereaved families are discussed. To conclude, we argue for the benefits of inviting bereaved parents whose children died after treatment completion in survivorship research. Such parents' early survivorship experiences will otherwise be systemically neglected. We argue that discussing complex cases can assist researchers to protect participants' and researchers' emotional well-being. We hope to contribute to the dearth of discussion about research operating procedures to address these issues.

As experience is gained with toxicology testing and as new assays and technologies are developed, it is critical for stakeholders to discuss opportunities to advance our overall testing strategies. To facilitate these discussions, a workshop on practices for assessing immunotoxicity for environmental chemicals was held with the goal of sharing perspectives on immunotoxicity testing strategies and experiences, developmental immunotoxicity (DIT), and integrated and alternative approaches to immunotoxicity testing. Experiences across the chemical and pharmaceutical industries suggested that standard toxicity studies, combined with triggered-based testing approaches, represent an effective and efficient approach to evaluate immunotoxic potential. Additionally, discussions on study design, critical windows, and new guideline approaches and experiences identified important factors to consider before initiating DIT evaluations including assay choice and timing and the impact of existing adult data. Participants agreed that integrating endpoints into standard repeat-dose studies should be considered for fulfilling any immunotoxicity testing requirements, while also maximizing information and reducing animal use. Participants also acknowledged that in vitro evaluation of immunosuppression is complex and may require the use of multiple assays that are still being developed. These workshop discussions should contribute to developing an effective but more resource and animal efficient approach for evaluating chemical immunotoxicity. Copyright © 2013 Elsevier Inc.

Examining the Professional Development Experiences and Non-Technical Skills Desired for Geoscience Employment

NASA Astrophysics Data System (ADS)

Houlton, H. R.; Ricci, J.; Wilson, C. E.; Keane, C.

2014-12-01

Professional development experiences, such as internships, research presentations and professional network building, are becoming increasingly important to enhance students' employability post-graduation. The practical, non-technical skills that are important for succeeding during these professional development experiences, such as public speaking, project management, ethical practices and writing, transition well and are imperative to the workplace. Thereby, graduates who have honed these skills are more competitive candidates for geoscience employment. Fortunately, the geoscience community recognizes the importance of these professional development opportunities and the skills required to successfully complete them, and are giving students the chance to practice non-technical skills while they are still enrolled in academic programs. The American Geosciences Institute has collected data regarding students' professional development experiences, including the preparation they receive in the corresponding non-technical skills. This talk will discuss the findings of two of AGI's survey efforts - the Geoscience Student Exit Survey and the Geoscience Careers Master's Preparation Survey (NSF: 1202707). Specifically, data highlighting the role played by internships, career opportunities and the complimentary non-technical skills will be discussed. As a practical guide, events informed by this research, such as AGI's professional development opportunities, networking luncheons and internships, will also be included.

2011-01-01

Context The use of peer facilitators in health-programs has great potential. One important application is prevention and control of type 2 diabetes among American Indians. Purpose To explore the experience of American Indian facilitators in a culturally appropriate intervention (Talking Circles) on 2 Northern Plains reservations. The Talking Circles offered a forum for educational dialogue on diabetes risk factors and the management of type 2 diabetes. Methods Phenomenology, a qualitative research approach, was used to answer the research question: “What did Native Talking Circle facilitators-experience?” Participants were 4 lay health workers from the intervention reservations who had been trained to present a diabetes curriculum while coordinating and guiding the group discussion. During open-ended, taped interviews, the facilitators shared their experiences conducting the Talking Circles. Analysis categorized the experiences into common themes to explain the phenomena and cultural construction of oral discussions (Talking Circles) of diabetes. Findings Themes included the concept of “a calling” to do the work, which included a self-growth process, a blending of 2 worldviews as a diabetes intervention strategy, the importance of translating educational materials in a liaison role, and commitment to tribal people and communities. Conclusions The experience of the facilitators was positive because they were knowledgeable about American Indian culture arid worldview arid were trained in both Talking Circle facilitation and type 2 diabetes.

Scintillation Detector for the Measurement of Ultra-Heavy Cosmic Rays on the Super-TIGER Experiment

NASA Technical Reports Server (NTRS)

Link, Jason

2011-01-01

We discuss the design and construction of the scintillation detectors for the Super-TIGER experiment. Super-TIGER is a large-area (5.4sq m) balloon-borne experiment designed to measure the abundances of cosmic-ray nuclei between Z= 10 and Z=56. It is based on the successful TIGER experiment that flew in Antarctica in 2001 and 2003. Super-TIGER has three layers of scintillation detectors, two Cherenkov detectors and a scintillating fiber hodoscope. The scintillation detector employs four wavelength shifter bars surrounding the edges of the scintillator to collect the light from particles traversing the detector. PMTs are optically coupled at both ends of the bars for light collection. We report on laboratory performance of the scintillation counters using muons. In addition we discuss the design challenges and detector response over this broad charge range including the effect of scintilator saturation.

Inclusion of quasi-experimental studies in systematic reviews of health systems research.

PubMed

Rockers, Peter C; Røttingen, John-Arne; Shemilt, Ian; Tugwell, Peter; Bärnighausen, Till

2015-04-01

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.

1991-01-01

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.

Computation and Experiment: A Powerful Combination to Understand and Predict Reactivities.

PubMed

Sperger, Theresa; Sanhueza, Italo A; Schoenebeck, Franziska

2016-06-21

Computational chemistry has become an established tool for the study of the origins of chemical phenomena and examination of molecular properties. Because of major advances in theory, hardware and software, calculations of molecular processes can nowadays be done with reasonable accuracy on a time-scale that is competitive or even faster than experiments. This overview will highlight broad applications of computational chemistry in the study of organic and organometallic reactivities, including catalytic (NHC-, Cu-, Pd-, Ni-catalyzed) and noncatalytic examples of relevance to organic synthesis. The selected examples showcase the ability of computational chemistry to rationalize and also predict reactivities of broad significance. A particular emphasis is placed on the synergistic interplay of computations and experiments. It is discussed how this approach allows one to (i) gain greater insight than the isolated techniques, (ii) inspire novel chemistry avenues, and (iii) assist in reaction development. Examples of successful rationalizations of reactivities are discussed, including the elucidation of mechanistic features (radical versus polar) and origins of stereoselectivity in NHC-catalyzed reactions as well as the rationalization of ligand effects on ligation states and selectivity in Pd- and Ni-catalyzed transformations. Beyond explaining, the synergistic interplay of computation and experiments is then discussed, showcasing the identification of the likely catalytically active species as a function of ligand, additive, and solvent in Pd-catalyzed cross-coupling reactions. These may vary between mono- or bisphosphine-bound or even anionic Pd complexes in polar media in the presence of coordinating additives. These fundamental studies also inspired avenues in catalysis via dinuclear Pd(I) cycles. Detailed mechanistic studies supporting the direct reactivity of Pd(I)-Pd(I) with aryl halides as well as applications of air-stable dinuclear Pd(I) catalysts are discussed. Additional combined experimental and computational studies are described for alternative metals, these include the discussion of the factors that control C-H versus C-C activation in the aerobic Cu-catalyzed oxidation of ketones, and ligand and additive effects on the nature and favored oxidation state of the active catalyst in Ni-catalyzed trifluoromethylthiolations of aryl chlorides. Examples of successful computational reactivity predictions along with experimental verifications are then presented. This includes the design of a fluorinated ligand [(CF3)2P(CH2)2P(CF3)2] for the challenging reductive elimination of ArCF3 from Pd(II) as well as the guidance of substrate scope (functional group tolerance and suitable leaving group) in the Ni-catalyzed trifluoromethylthiolation of C(sp(2))-O bonds. In summary, this account aims to convey the benefits of integrating computational studies in experimental research to increase understanding of observed phenomena and guide future experiments.

PubMed

Reddy, Madhavi K; Polusny, Melissa A; Murdoch, Maureen

2009-12-01

Some traumatic stress research surveys are potentially subject to context effects, such as priming, because they include questions about traumatic experiences and trauma-related symptoms within the same survey. In this study, asking about traumatic experiences before or after asking about PTSD influenced symptom reporting was investigated in a sample of 424 National Guard soldiers. Results indicate ordering of symptom measures immediately before or after reports of combat experiences did not influence reports of PTSD symptoms. Implications of results are discussed.

Psychosocial experiences and needs of Australian caregivers of people with stroke: prognosis messages, caregiver resilience, and relationships.

PubMed

El Masry, Yasmeen; Mullan, Barbara; Hackett, Maree

2013-01-01

Despite stroke being the most common form of cerebrovascular disease, there has been relatively little attention paid to the psychosocial experiences and needs of Australian caregivers of people who have had a stroke. Twenty Australian informal caregivers and 10 stroke survivors participated in individual semi-structured qualitative interviews covering all aspects of caregiving, including stroke survivors' views on their caregiver's experiences. The 5 interrelated topics most discussed were changes in relationships and support services, including being told to expect a poor outcome; caregiver attributes and coping strategies; stroke survivor limitations; external employment and financial stressors; and unexpected positive changes in relationships and priorities. Caring for a stroke survivor involves a complex interaction of these factors that appear to be moderated by the quality of the pre-existing stroke survivor-caregiver relationship and the poststroke coping strategies used. Particular attention should be paid to how prognosis is conveyed and whether appropriate outpatient services are available. Clinicians should also consider discussing appropriate caregiver coping strategies and the quality of the relationship between the stroke survivor and caregiver.

Comparison of Commercial EMI Test Techniques to NASA EMI Test Techniques

NASA Astrophysics Data System (ADS)

Smith, Valerie

2000-11-01

This systems report describes how the Optical Properties Monitor (OPM) experiment was developed. Pertinent design parameters are discussed, along with mission information and system requirements to successfully complete the mission. Environmental testing was performed on the OPM to certify it for spaceflight. This testing included vibration, thermal vacuum, electromagnetic interference and conductance, and toxicity tests. Instrument and monitor subsystem performances, including the reflectometer, vacuum ultraviolet, total integrated scatter, atomic oxygen monitor, irradiance monitor, and molecular contamination monitor during the mission are discussed. The OPM experiment was launched aboard the Space Shuttle on mission STS-81 in January 1997 and transferred to the Mir space station. An extravehicular activity (EVA) was performed in April 1997 to attach the OPM experiment to the outside of the Mir/Shuttle Docking Module for space environment exposure. The OPM conducted in situ measurements of a number of material samples. These data may be found in the OPM Science Report. OPM was retrieved during an EVA in January 1998 and was returned to Earth on board the Space Shuttle on mission STS-89.

End-of-life experiences and expectations of Africans in Australia: cultural implications for palliative and hospice care.

PubMed

Hiruy, Kiros; Mwanri, Lillian

2014-03-01

The ageing and frail migrants who are at the end of life are an increasing share of migrants living in Australia. However, within such populations, information about end-of-life experiences is limited, particularly among Africans. This article provides some insights into the sociocultural end-of-life experiences of Africans in Australia and their interaction with the health services in general and end-of-life care in particular. It provides points for discussion to consider an ethical framework that include Afro-communitarian ethical principles to enhance the capacity of current health services to provide culturally appropriate and ethical care. This article contributes to our knowledge regarding the provision of culturally appropriate and ethical care to African patients and their families by enabling the learning of health service providers to improve the competence of palliative care systems and professionals in Australia. Additionally, it initiates the discussion to highlight the importance of paying sufficient attention to a diverse range of factors including the migration history when providing palliative and hospice care for patients from African migrant populations.

Disclosure of Parental HIV Status to Children: Experiences of Adults Receiving Antiretroviral Treatment at an Urban Clinic in Kampala, Uganda

PubMed Central

Okuga, Monica; Nabirye, Rose Chalo; Sewankambo, Nelson Kaulukusi; Nakanjako, Damalie

2017-01-01

Limited data are available on the experiences of parental HIV disclosure to children in Uganda. We conducted a qualitative study comprising sixteen in-depth interviews and four focus group discussions with parents receiving highly active antiretroviral therapy. Analysis was done using Atlas.ti qualitative research software. Back-and-forth triangulation was done between transcripts of the in-depth interviews and focus group discussions, and themes and subthemes were developed. Barriers to parents' disclosure included perceptions that children are too young to understand what HIV infection means and fears of secondary disclosure by the children. Immediate outcomes of disclosure included children getting scared and crying, although such instances often gave way to more enduring positive experiences for the parents, such as support in adherence to medical care, help in household chores, and a decrease in financial demands from the children. Country-specific interventions are needed to improve the process of parental HIV disclosure to children and this should encompass preparation on how to deal with the immediate psychological challenges associated with the parent's disclosure.

This lesson explores the use of different management leadership styles and methods that are applied to disaster management situations. Leadership and command are differentiated. Mechanisms that can be used to influence others developed include: 1) coercion; 2) reward; 3) position; 4) knowledge; and 5) admiration. Factors that affect leadership include: 1) individual characteristics; 2) competence; 3) experience; 4) self-confidence; 5) judgment; 6) decision-making; and 8) style. Experience and understanding the task are important factors for leadership. Four styles of leadership are developed: 1) directive; 2) supportive; 3) participative; and 4) achievement oriented. Application of each of these styles is discussed. The styles are discussed further as they relate to the various stages of a disaster. The effects of interpersonal relationships and the effects of the environment are stressed. Lastly, leadership does not just happen because a person is appointed as a manager--it must be earned.

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.

Miller, David C.; Kempe, Michael D.; Muller, Matthew T.

We examined the durability of polymeric encapsulation materials using outdoor exposure at the nominal geometric concentration of 500 suns. The results for 36-month cumulative field deployment are presented for materials including: poly(ethylene-co-vinyl acetate), (EVA); polyvinyl butyral (PVB); ionomer; polyethylene/polyoctene copolymer (PO); thermoplastic polyurethane (TPU); poly(dimethylsiloxane) (PDMS); poly(diphenyl dimethyl siloxane) (PDPDMS); and poly(phenyl-methyl siloxane) (PPMS). Measurements of the field conditions including ambient temperature and ultraviolet (UV) dose were recorded at the test site during the experiment. Our measurements for the experiment included optical transmittance (with subsequent analysis of solar-weighted transmittance, UV cut-off wavelength, and yellowness index), mass, visual photography, photoelastic imaging,more » and fluorescence spectroscopy. While the results to date for EVA are presented and discussed, examination here focuses more on the siloxane materials. A specimen recently observed to fail by thermal decomposition is discussed in terms of the implementation of the experiment as well as its fluorescence signature, which was observed to become more pronounced with age. Modulated thermogravimetry (allowing determination of the activation energy of thermal decomposition) was performed on a subset of the siloxanes to quantify the propensity for decomposition at elevated temperatures. Supplemental, Pt-catalyst- and primer-solutions as well as peroxide-cured PDMS specimens were examined to assess the source of the luminescence. Furthermore, our results, including the change in optical transmittance, observed failure modes, and subsequent analyses of the failure modes are described in the conclusions.« less

Fossey, Ellie; Farhall, John; Foley, Fiona; Thomas, Neil

2018-01-01

Background Digital interventions offer an innovative way to make the experiences of people living with mental illness available to others. As part of the Self-Management And Recovery Technology (SMART) research program on the use of digital resources in mental health services, an interactive website was developed including videos of people with lived experience of mental illness discussing their recovery. These peer videos were designed to be watched on a tablet device with a mental health worker, or independently. Objective Our aim was to explore how service users experienced viewing the lived experience videos on this interactive website, as well as its influence on their recovery journey. Methods In total, 36 service users with experience of using the website participated in individual semistructured qualitative interviews. All participants had experience of psychosis. Data analysis occurred alongside data collection, following principles of constructivist grounded theory methodology. Results According to participants, engaging with lived experience videos was a pivotal experience of using the website. Participants engaged with peers through choosing and watching the videos and reflecting on their own experience in discussions that opened up with a mental health worker. Benefits of seeing others talking about their experience included “being inspired,” “knowing I’m not alone,” and “believing recovery is possible.” Experiences of watching the videos were influenced by the participants’ intrapersonal context, particularly their ways of coping with life and use of technology. The interpersonal context of watching the videos with a worker, who guided website use and facilitated reflection, enriched the experience. Conclusions Engaging with lived experience videos was powerful for participants, contributing to their feeling connected and hopeful. Making websites with lived experience video content available to service users and mental health workers demonstrates strong potential to support service users’ recovery. PMID:29739737

When the globe is your classroom: teaching and learning about large-scale environmental change online

NASA Astrophysics Data System (ADS)

Howard, E. A.; Coleman, K. J.; Barford, C. L.; Kucharik, C.; Foley, J. A.

2005-12-01

Understanding environmental problems that cross physical and disciplinary boundaries requires a more holistic view of the world - a "systems" approach. Yet it is a challenge for many learners to start thinking this way, particularly when the problems are large in scale and not easily visible. We will describe our online university course, "Humans and the Changing Biosphere," which takes a whole-systems perspective for teaching regional to global-scale environmental science concepts, including climate, hydrology, ecology, and human demographics. We will share our syllabus and learning objectives and summarize our efforts to incorporate "best" practices for online teaching. We will describe challenges we have faced, and our efforts to reach different learner types. Our goals for this presentation are: (1) to communicate how a systems approach ties together environmental sciences (including climate, hydrology, ecology, biogeochemistry, and demography) that are often taught as separate disciplines; (2) to generate discussion about challenges of teaching large-scale environmental processes; (3) to share our experiences in teaching these topics online; (4) to receive ideas and feedback on future teaching strategies. We will explain why we developed this course online, and share our experiences about benefits and challenges of teaching over the web - including some suggestions about how to use technology to supplement face-to-face learning experiences (and vice versa). We will summarize assessment data about what students learned during the course, and discuss key misconceptions and barriers to learning. We will highlight the role of an online discussion board in creating classroom community, identifying misconceptions, and engaging different types of learners.

Burton, Candace W; Halpern-Felsher, Bonnie; Rankin, Sally H; Rehm, Roberta S; Humphreys, Janice C

2011-06-01

Adolescent dating abuse is not specifically described by any current nursing theory, and this article presents discussion of some existing theories that could inform a nursing theory of adolescent dating abuse. To account for the effects of gender, this discussion is limited to young women. Adolescent dating abuse is an important and understudied international issue for nursing. Theoretical frameworks can support development of nursing scholarship for such issues. No single theory yet exists in nursing to explain the experiences and health ramifications of dating abuse among young women. A summary table of theories is provided. Literature was gathered via database search and bibliographic snowballing from reference lists of relevant articles. Included literature dates from 1982 through 2010. Theories of relationship formation and function are discussed, including attachment, investment, feminist and gender role conflict theories. Betrayal trauma theory is considered as a mechanism of injury following an abusive dating experience. Gender, relationship and adolescence combine in a complex developmental moment for young women. To improve nursing care for those at risk for or in the throes of abusive relationships, it is critical to develop specific nursing approaches to understanding these relationships. Existing theories related to relationship and traumatic experiences can be combined in the development of a nursing theory of adolescent dating abuse among young women. © 2011 The Authors.

Statistical analysis of microgravity experiment performance using the degrees of success scale

NASA Technical Reports Server (NTRS)

Upshaw, Bernadette; Liou, Ying-Hsin Andrew; Morilak, Daniel P.

1994-01-01

This paper describes an approach to identify factors that significantly influence microgravity experiment performance. Investigators developed the 'degrees of success' scale to provide a numerical representation of success. A degree of success was assigned to 293 microgravity experiments. Experiment information including the degree of success rankings and factors for analysis was compiled into a database. Through an analysis of variance, nine significant factors in microgravity experiment performance were identified. The frequencies of these factors are presented along with the average degree of success at each level. A preliminary discussion of the relationship between the significant factors and the degree of success is presented.

Retrospective North American CFL Experience Curve Analysis and Correlation to Deployment Programs

DOE Office of Scientific and Technical Information (OSTI.GOV)

Smith, Sarah J.; Wei, Max; Sohn, Michael D.

Retrospective experience curves are a useful tool for understanding historic technology development, and can contribute to investment program analysis and future cost estimation efforts. This work documents our development of an analysis approach for deriving retrospective experience curves with a variable learning rate, and its application to develop an experience curve for compact fluorescent lamps for the global and North American markets over the years 1990-2007. Uncertainties and assumptions involved in interpreting data for our experience curve development are discussed, including the processing and transformation of empirical data, the selection of system boundaries, and the identification of historical changes inmore » the learning rate over the course of 15 years. In the results that follow, we find that that the learning rate has changed at least once from 1990-2007. We also explore if, and to what degree, public deployment programs may have contributed to an increased technology learning rate in North America. We observe correlations between the changes in the learning rate and the initiation of new policies, abrupt technological advances, including improvements to ballast technology, and economic and political events such as trade tariffs and electricity prices. Finally, we discuss how the findings of this work (1) support the use of segmented experience curves for retrospective and prospective analysis and (2) may imply that investments in technological research and development have contributed to a change in market adoption and penetration.« less

PubMed Central

Vose, Alicia; Nonnenmacher, Jodi; Singer, Michele L.; González-Fernández, Marlís

2014-01-01

Swallowing dysfunction is common after stroke. More than 50% of the 665 thousand stroke survivors will experience dysphagia acutely of which approximately 80 thousand will experience persistent dysphagia at 6 months. The physiologic impairments that result in post-stroke dysphagia are varied. This review focuses primarily on well-established dysphagia treatments in the context of the physiologic impairments they treat. Traditional dysphagia therapies including volume and texture modifications, strategies such as chin tuck, head tilt, head turn, effortful swallow, supraglottic swallow, super-supraglottic swallow, Mendelsohn maneuver and exercises such as the Shaker exercise and Masako (tongue hold) maneuver are discussed. Other more recent treatment interventions are discussed in the context of the evidence available. PMID:26484001

Lorelle, Sonya; Grothaus, Tim

2015-10-01

While numerous programs aim to mediate the risks for children experiencing homelessness, there is a lack of research representing the children's and parents' perspectives in supportive housing programs. With this phenomenological qualitative study, the authors share the voices of 22 participants, including children and their families, regarding their experiences while receiving services from a homeless agency. Participating parents perceived that the program provided resources to the children that they could not provide themselves, opportunities for exposure to positive new experiences, and improved psychosocial outcomes for their children. Participants also discussed desired program changes and the responsiveness of agency staff regarding unmet needs of the children. Implications for policies and programs are discussed.

Osborn, D. E.; Lynch, D. C.; Fozzolari, R.

1991-01-01

A technique for photo generation of radicals is discussed that can be used in the recovery of oxygen and metals from extraterrestrial resources. The concept behind this work was to examine methods whereby radicals can be generated and used in the processing of refractory materials. In that regard, the focus is on the use of sunlight. Sunlight provides useful energy for processing in the forms of both thermal and quantum energy. A number of experiments were conducted in the chlorination of metals with and without the aid of UV and near UV light. The results of some of those experiments are discussed.

Reflections of Educators in Pursuit of Inclusive Science Classrooms

NASA Astrophysics Data System (ADS)

Kirch, Susan A.; Bargerhuff, Mary Ellen; Cowan, Heidi; Wheatly, Michele

2007-08-01

General education science teachers are meeting increasingly diverse classrooms of students that include students with disabilities. A one-week, summer, residential workshop was offered to interested science and special educators who worked through lab experiments one-on-one with students with physical or sensory disabilities (grades 7-12). To determine how effective this professional development workshop was at raising disability awareness and providing teacher training in inclusive science teaching practices, a combination of survey and reflective journal entries was used to monitor participants’ experience. Here we discuss the findings from this benchmark study and discuss how others might adapt this professional development model for use by schools interested in moving toward inclusive practices.

The generation and amplification of intergalactic magnetic fields in analogue laboratory experiments with high power lasers

NASA Astrophysics Data System (ADS)

Gregori, G.; Reville, B.; Miniati, F.

2015-11-01

The advent of high-power laser facilities has, in the past two decades, opened a new field of research where astrophysical environments can be scaled down to laboratory dimensions, while preserving the essential physics. This is due to the invariance of the equations of magneto-hydrodynamics to a class of similarity transformations. Here we review the relevant scaling relations and their application in laboratory astrophysics experiments with a focus on the generation and amplification of magnetic fields in cosmic environment. The standard model for the origin of magnetic fields is a multi stage process whereby a vanishing magnetic seed is first generated by a rotational electric field and is then amplified by turbulent dynamo action to the characteristic values observed in astronomical bodies. We thus discuss the relevant seed generation mechanisms in cosmic environment including resistive mechanism, collision-less and fluid instabilities, as well as novel laboratory experiments using high power laser systems aimed at investigating the amplification of magnetic energy by magneto-hydrodynamic (MHD) turbulence. Future directions, including efforts to model in the laboratory the process of diffusive shock acceleration are also discussed, with an emphasis on the potential of laboratory experiments to further our understanding of plasma physics on cosmic scales.

How information about other people's personal experiences can help with healthcare decision-making: a qualitative study.

PubMed

Entwistle, Vikki Ann; France, Emma F; Wyke, Sally; Jepson, Ruth; Hunt, Kate; Ziebland, Sue; Thompson, Andrew

2011-12-01

To investigate people's views of using 'general facts' and information about other people's 'personal experiences' for health-related decision-making. Sixty-two people, who between them had experience of five different focal health issues, participated in 12 focus groups and 9 interviews. Exploration of uses of the two types of information was supported by discussion of illustrative excerpts. There was less discussion of 'general facts'; participants thought it obvious that good decisions required these. Participants reported having used 'personal experiences' information to: recognise decisions that needed consideration; identify options; appraise options and make selections (including by developing and reflecting on their reasoning about possible choices); and support coping strategies. Their inclination to use 'personal experiences' information was apparently moderated by assessments of personal relevance, the motives of information providers and the 'balance' of experiences presented. People can use 'personal experiences' information in various ways to support their decision-making, and exercise some discrimination as they do. 'Personal experiences' information may help people in a number of ways in relation to decision-making. However, 'personal experiences' information does not replace the need for 'general facts' and care should be taken when it is used in resources for patients. Copyright © 2011 Elsevier Ireland Ltd.

CO2 cycle

USGS Publications Warehouse

Titus, Timothy N.; Byrne, Shane; Colaprete, Anthony; Forget, Francois; Michaels, Timothy I.; Prettyman, Thomas H.

2017-01-01

This chapter discusses the use of models, observations, and laboratory experiments to understand the cycling of CO2 between the atmosphere and seasonal Martian polar caps. This cycle is primarily controlled by the polar heat budget, and thus the emphasis here is on its components, including solar and infrared radiation, the effect of clouds (water- and CO2-ice), atmospheric transport, and subsurface heat conduction. There is a discussion about cap properties including growth and regression rates, albedos and emissivities, grain sizes and dust and/or water-ice contamination, and curious features like cold gas jets and araneiform (spider-shaped) terrain. The nature of the residual south polar cap is discussed as well as its long-term stability and ability to buffer atmospheric pressures. There is also a discussion of the consequences of the CO2 cycle as revealed by the non-condensable gas enrichment observed by Odyssey and modeled by various groups.

Gas-grain simulation experiment module conceptual design and gas-grain simulation facility breadboard development

NASA Technical Reports Server (NTRS)

Zamel, James M.; Petach, Michael; Gat, Nahum; Kropp, Jack; Luong, Christina; Wolff, Michael

1993-01-01

This report delineates the Option portion of the Phase A Gas-Grain Simulation Facility study. The conceptual design of a Gas-Grain Simulation Experiment Module (GGSEM) for Space Shuttle Middeck is discussed. In addition, a laboratory breadboard was developed during this study to develop a key function for the GGSEM and the GGSF, specifically, a solid particle cloud generating device. The breadboard design and test results are discussed and recommendations for further studies are included. The GGSEM is intended to fly on board a low earth orbit (LEO), manned platform. It will be used to perform a subset of the experiments planned for the GGSF for Space Station Freedom, as it can partially accommodate a number of the science experiments. The outcome of the experiments performed will provide an increased understanding of the operational requirements for the GGSF. The GGSEM will also act as a platform to accomplish technology development and proof-of-principle experiments for GGSF hardware, and to verify concepts and designs of hardware for GGSF. The GGSEM will allow assembled subsystems to be tested to verify facility level operation. The technology development that can be accommodated by the GGSEM includes: GGSF sample generation techniques, GGSF on-line diagnostics techniques, sample collection techniques, performance of various types of sensors for environmental monitoring, and some off-line diagnostics. Advantages and disadvantages of several LEO platforms available for GGSEM applications are identified and discussed. Several of the anticipated GGSF experiments require the deagglomeration and dispensing of dry solid particles into an experiment chamber. During the GGSF Phase A study, various techniques and devices available for the solid particle aerosol generator were reviewed. As a result of this review, solid particle deagglomeration and dispensing were identified as key undeveloped technologies in the GGSF design. A laboratory breadboard version of a solid particle generation system was developed and characterization tests performed. The breadboard hardware emulates the functions of the GGSF solid particle cloud generator in a ground laboratory environment, but with some modifications, can be used on other platforms.

McGuire, Thomas

2017-10-01

The Lockheed Martin Compact Fusion Reactor (CFR) Program endeavors to quickly develop a compact fusion power plant with favorable commercial economics and military utility. The CFR uses a diamagnetic, high beta, magnetically encapsulated, linear ring cusp plasma confinement scheme. Major project activities will be reviewed, including the T4B and T5 plasma heating experiments. The goal of the experiments is to demonstrate a suitable plasma target for heating experiments, to characterize the behavior of plasma sources in the CFR configuration and to then heat the plasma with neutral beams, with the plasma transitioning into the high Beta confinement regime. The design and preliminary results of the experiments will be presented, including discussion of predicted behavior, plasma sources, heating mechanisms, diagnostics suite and relevant numerical modeling. ©2017 Lockheed Martin Corporation.

Working with LGBT Individuals: Incorporating Positive Psychology into Training and Practice.

PubMed

Lytle, Megan C; Vaughan, Michelle D; Rodriguez, Eric M; Shmerler, David L

2014-10-01

This paper examines how positive psychology principles can be incorporated into clinical training and practice to work with lesbian, gay, bisexual and transgender (LGBT) clients. LGBT psychology literature has all too often relied on heterosexual and cisgender reference groups as the norm with respect to psychological health, primarily framing the experiences of LGBT individuals through the lens of psychopathology. As a result, strengths that could be ascribed to the LGBT experience have been overlooked within training and practice. While positive psychology is actively being incorporated into clinical and counseling psychology curricula, broadening the paradigm to include LGBT individuals has generally not been included in the discussion. Specific recommendations for training psychologists to incorporate and foster positive social institutions, positive subjective experiences and character strengths when working with LGBT clients and celebrating their unique experiences are provided.

Mars Pathfinder flight system integration and test.

NASA Astrophysics Data System (ADS)

Muirhead, B. K.

This paper describes the system integration and test experiences, problems and lessons learned during the assembly, test and launch operations (ATLO) phase of the Mars Pathfinder flight system scheduled to land on the surface of Mars on July 4, 1997. The Mars Pathfinder spacecraft consists of three spacecraft systems: cruise stage, entry vehicle and lander. The cruise stage carries the entry and lander vehicles to Mars and is jettisoned prior to entry. The entry vehicle, including aeroshell, parachute and deceleration rockets, protects the lander during the direct entry and reduces its velocity from 7.6 to 0 km/s in stages during the 5 min entry sequence. The lander's touchdown is softened by airbags which are retracted once stopped on the surface. The lander then uprights itself, opens up fully and begins surface operations including deploying its camera and rover. This paper overviews the system design and the results of the system integration and test activities, including the entry, descent and landing subsystem elements. System test experiences including science instruments, the microrover, Sojourner, and software are discussed. The final qualification of the entry, descent and landing subsystems during this period is also discussed.

LGBTQ Youth's Perceptions of Primary Care.

Snyder, Barbara K; Burack, Gail D; Petrova, Anna

2017-05-01

Despite published guidelines on the need to provide comprehensive care to lesbian, gay, bisexual, transgender, and questioning/queer (LGBTQ) youth, there has been limited research related to the deliverance of primary health care to this population. The goals of this study were to learn about LGBTQ youth's experiences with their primary care physicians and to identify areas for improvement. Youth attending 1 of 5 community-based programs completed a written questionnaire and participated in a focus group discussion regarding experiences at primary care visits, including topics discussed, counselling received, and physician communication. Most of the youth did not feel their health care needs were well met. The majority acknowledged poor patient-provider communication, disrespect, and lack of discussions about important topics such as sexual and emotional health. Participants cited concerns about confidentiality and inappropriate comments as barriers to care. Youth expressed a strong desire to have physicians be more aware of their needs and concerns.

Galileo Attitude Determination: Experiences with a Rotating Star Scanner

NASA Technical Reports Server (NTRS)

Merken, L.; Singh, G.

1991-01-01

The Galileo experience with a rotating star scanner is discussed in terms of problems encountered in flight, solutions implemented, and lessons learned. An overview of the Galileo project and the attitude and articulation control subsystem is given and the star scanner hardware and relevant software algorithms are detailed. The star scanner is the sole source of inertial attitude reference for this spacecraft. Problem symptoms observed in flight are discussed in terms of effects on spacecraft performance and safety. Sources of thse problems include contributions from flight software idiosyncrasies and inadequate validation of the ground procedures used to identify target stars for use by the autonomous on-board star identification algorithm. Problem fixes (some already implemented and some only proposed) are discussed. A general conclusion is drawn regarding the inherent difficulty of performing simulation tests to validate algorithms which are highly sensitive to external inputs of statistically 'rare' events.

Psychosocial experiences associated with confirmed and self-identified dyslexia: a participant-driven concept map of adult perspectives.

PubMed

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.

Usta, Jinan; Makarem, Nisrine N; Habib, Rima R

2013-03-01

This article explores the experiences and perceptions of Lebanese women and men with economic abuse. Data were drawn from focus group discussions and face-to-face interviews with men, women and social workers. The findings reveal that Lebanese women experience many forms of economic abuse, including the withholding of earnings, restricted involvement in the labor force, and limited purchasing decisions. Inheritance laws and practices still favor men over women. Women tolerate economic abuse to avoid more serious forms of abuse and ensure family stability. Practical implications of the findings are presented.

Mixed valent metals

Riseborough, P. S.; Lawrence, J. M.

2016-08-01

We review the theory of mixed-valent metals and make comparison with experiments. A single-impurity description of the mixed-valent state is discussed alongside the description of the nearly-integer valent or Kondo limit. The degeneracy N of the f-shell plays an important role in the description of the low-temperature Fermi-liquid state. In particular, for large N, there is a rapid cross-over between the mixed-valent and the Kondo limit when the number of f electrons is changed. We discuss the limitations on the application of the single-impurity description to concentrated compounds such as those caused by the saturation of the Kondo effect and those due to the presence of magnetic interactions between the impurities. This discussion is followed by a description of a periodic lattice of mixed-valent ions, including the role of the degeneracy N. The article concludes with a comparison of theory and experiment. Topics covered include the single-impurity Anderson model, Luttinger’s theorem, the Friedel sum rule, the Schrieffer-Wolff transformation, the single-impurity Kondo model, Kondo screening, the Wilson ratio, local Fermi-liquids, Fermi-liquid sum rules, the Noziéres exhaustion principle, Doniach’s diagram, the Anderson lattice model, the Slave-Boson method, etc.

Patient views on smoking, lung cancer, and stigma: a focus group perspective.

PubMed

Lehto, Rebecca H

2014-06-01

Patients with lung cancer, the leading cause of cancer death, are shown to have high levels of psychological distress and poorer quality of life as compared to patients with other cancer types. The purpose of this paper is to describe patient focus group discussions about the lung cancer experience in relation to perceived stigmatization, smoking behaviors, and illness causes; and to discuss implications of these findings relative to the role of the nurse as a patient advocate. Eleven adult lung cancer patients participated in audio taped focus group sessions. Discussion questions probed patient perceptions of lung cancer challenges and adaptation issues. Six primary themes from the qualitative analysis included: 1) societal attitudes; 2) institutional practices and experiences; 3) negative thoughts and emotions such as guilt, self-blame and self-deprecation, regret, and anger; 4) actual stigmatization experiences; 5) smoking cessation: personal choices versus addiction; and 6) causal attributions. Patients with lung cancer uniquely experience an added burden from developing an illness that the public recognizes is directly associated with smoking behaviors. Stigmatization and smoking related concerns are of high importance. Oncology nurses must be at the forefront in ensuring that patients with lung cancer do not experience additional burden from perceptions that they somehow deserve and need to defend why they have the illness that they are facing.

The experiment contained Data Matrix symbols applied using laser bonding, vacuum arc vapor deposition, gas assisted laser etch, chemical etch, mechanical dot peening, laser shot peening, and laser induced surface improvement. The effects of ultraviolet radiation on nickel acetate seal versus hot water seal on sulfuric acid anodized aluminum are discussed. These samples were exposed on the International Space Station to the low Earth orbital environment of atomic oxygen, ultraviolet radiation, thermal cycling, and hard vacuum, though atomic oxygen exposure was very limited for some samples. Results from the one-year exposure on MISSE-3 and MISSE-4 are compared to those from MISSE-1 and MISSE-2, which were exposed for four years. Part marking and identification materials on the current MISSE -6 experiment are also discussed.

Numerous arthropod species represent potential targets for gene-drive-based population suppression or replacement, including those that transmit diseases, damage crops, or act as deleterious invasive species. Containment measures for gene drive research in arthropods have been discussed in the literature, but the importance of developing safe and effective standard operating procedures (SOPs) for these types of experiments has not been adequately addressed. Concisely written SOPs link safe work practices, containment measures, institutional training, and research-specific protocols. Here we discuss information to be considered by principal investigators, biosafety officers, and institutional biosafety committees as they work together to develop SOPs for experiments involving gene drive in arthropods, and describe various courses of action that can be used to maintain the effectiveness of SOPs through evaluation and revision. The information provided herein will be especially useful to investigators and regulatory personnel who may lack extensive experience working with arthropods under containment conditions.

The Mpemba effect: When can hot water freeze faster than cold?

NASA Astrophysics Data System (ADS)

Jeng, Monwhea

2006-06-01

We review the Mpemba effect, where initially hot water freezes faster than initially cold water. Although the effect might appear impossible, it has been observed in numerous experiments and was discussed by Aristotle, Francis Bacon, Roger Bacon, and Descartes. It has a rich and fascinating history, including the story of the secondary school student, Erasto Mpemba, who reintroduced the effect to the twentieth century scientific community. The phenomenon is simple to describe and illustrates numerous important issues about the scientific method: the role of skepticism in scientific inquiry, the influence of theory on experiment and observation, the need for precision in the statement of a scientific hypothesis, and the nature of falsifiability. Proposed theoretical mechanisms for the Mpemba effect and the results of contemporary experiments on the phenomenon are surveyed. The observation that hot water pipes are more likely to burst than cold water pipes is also discussed.

Responsibility after the apparent end: 'following-up' in clinical ethics consultation.

PubMed

Finder, Stuart G; Bliton, Mark J

2011-09-01

Clinical ethics literature typically presents ethics consultations as having clear beginnings and clear ends. Experience in actual clinical ethics practice, however, reflects a different characterization, particularly when the moral experiences of ethics consultants are included in the discussion. In response, this article emphasizes listening and learning about moral experience as core activities associated with clinical ethics consultation. This focus reveals that responsibility in actual clinical ethics practice is generated within the moral scope of an ethics consultant's activities as she or he encounters the unique and specific features that emerge from interactions with a specific patient, or family, or practitioner within a given situation and over time. A long-form narrative about an ethics consultant's interactions is interwoven with a more didactic discussion to highlight the theme of responsibility and to probe questions that arise regarding follow-up within the practice of clinical ethics consultation. © 2011 Blackwell Publishing Ltd.

The durability of polymeric encapsulation materials was examined using outdoor exposure at the nominal geometric concentration of 500 suns. The results for 36 months cumulative field deployment are presented for materials including: poly(ethylene-co-vinyl acetate), (EVA); polyvinyl butyral (PVB); ionomer; polyethylene/ polyoctene copolymer (PO); thermoplastic polyurethane (TPU); poly(dimethylsiloxane) (PDMS); poly(diphenyl dimethyl siloxane) (PDPDMS); and poly(phenyl-methyl siloxane) (PPMS). Measurements of the field conditions including ambient temperature and ultraviolet (UV) dose were recorded at the test site during the experiment. Measurements for the experiment included optical transmittance (with subsequent analysis of solar-weighted transmittance, UV cut-off wavelength, and yellowness index), mass, visual photography, photoelasticmore » imaging, and fluorescence spectroscopy. While the results to date for EVA are presented and discussed, examination here focuses more on the siloxane materials. A specimen recently observed to fail by thermal decomposition is discussed in terms of the implementation of the experiment as well as its fluorescence signature, which was observed to become more pronounced with age. Modulated thermogravimetry (allowing determination of the activation energy of thermal decomposition) was performed on a subset of the siloxanes to quantify the propensity for decomposition at elevated temperatures. Supplemental, Pt-catalyst- and primer-solutions as well as peroxide-cured PDMS specimens were examined to assess the source of the luminescence. The results of the study including the change in optical transmittance, observed failure modes, and subsequent analyses of the failure modes are described in the conclusions.« less

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.

Flavored tobacco products have been shown to appeal to youth, however tobacco control strategies have traditionally not focused on these products. To inform the adaptation of an existing videogame to focus on the prevention of flavored tobacco product use, this study explored adolescents' perceptions, beliefs, and social norms surrounding these products, including flavored e-cigarettes. We conducted and analyzed transcripts from seven focus groups with 11-17-year-old adolescents (n = 33) from after-school programs in CT and CA in 2016. Participants discussed flavored tobacco product beliefs and experiences, and how these compared to traditional cigarettes. Thematic analysis of transcripts revealed that participants could name flavors in tobacco products, even though few discussed first-hand experience with the products. Most groups perceived that flavored tobacco product and flavored e-cigarette use facilitated peer approval and acceptance. All groups discussed how youth could easily access flavored tobacco products, including e-cigarettes. Flavoring was a salient aspect of e-cigarette advertisements; however the groups did not recall exposure to other types of flavored tobacco product counter-marketing. These data can help inform the development of tobacco control strategies, novel interventions (such as videogames), and future FDA efforts to prevent adolescent tobacco product use through education and risk communication.

2016-01-01

The NASA Juncture Flow experiment is a new effort whose focus is attaining validation data in the juncture region of a wing-body configuration. The experiment is designed specifically for the purpose of CFD validation. Current turbulence models routinely employed by Reynolds-averaged Navier-Stokes CFD are inconsistent in their prediction of corner flow separation in aircraft juncture regions, so experimental data in the near-wall region of such a configuration will be useful both for assessment as well as for turbulence model improvement. This paper summarizes the Juncture Flow effort to date, including preliminary risk-reduction experiments already conducted and planned future experiments. The requirements and challenges associated with conducting a quality validation test are discussed.

Migrant Sexual Health Help-Seeking and Experiences of Stigmatization and Discrimination in Perth, Western Australia: Exploring Barriers and Enablers

2016-01-01

Increasing HIV notifications amongst migrant and mobile populations to Australia is a significant public health issue. Generalizations about migrant health needs and delayed or deterred help-seeking behaviors can result from disregarding the variation between and within cultures including factors, such as drivers for migration and country of birth. This study explored barriers and enablers to accessing sexual health services, including experiences of stigma and discrimination, within a purposive sample of sub-Saharan African, Southeast Asian, and East Asian migrants. A qualitative design was employed using key informant interviews and focus group discussions. A total of 45 people with ages ranging from 18 to 50 years, participated in focus group discussions. Common barriers and enablers to help seeking behaviors were sociocultural and religious influence, financial constraints, and knowledge dissemination to reduce stigma. Additionally, common experiences of stigma and discrimination were related to employment and the social and self-isolation of people living with HIV. Overcoming barriers to accessing sexual health services, imparting sexual health knowledge, recognizing variations within cultures, and a reduction in stigma and discrimination will simultaneously accelerate help-seeking and result in better sexual health outcomes in migrant populations.

Perceptual Anomalies in Schizophrenia: Integrating Phenomenology and Cognitive Neuroscience

PubMed Central

Uhlhaas, Peter J.; Mishara, Aaron L.

2007-01-01

From phenomenological and experimental perspectives, research in schizophrenia has emphasized deficits in “higher” cognitive functions, including attention, executive function, as well as memory. In contrast, general consensus has viewed dysfunctions in basic perceptual processes to be relatively unimportant in the explanation of more complex aspects of the disorder, including changes in self-experience and the development of symptoms such as delusions. We present evidence from phenomenology and cognitive neuroscience that changes in the perceptual field in schizophrenia may represent a core impairment. After introducing the phenomenological approach to perception (Husserl, the Gestalt School), we discuss the views of Paul Matussek, Klaus Conrad, Ludwig Binswanger, and Wolfgang Blankenburg on perception in schizophrenia. These 4 psychiatrists describe changes in perception and automatic processes that are related to the altered experience of self. The altered self-experience, in turn, may be responsible for the emergence of delusions. The phenomenological data are compatible with current research that conceptualizes dysfunctions in perceptual processing as a deficit in the ability to combine stimulus elements into coherent object representations. Relationships of deficits in perceptual organization to cognitive and social dysfunction as well as the possible neurobiological mechanisms are discussed. PMID:17118973

Curriculum reform in medical schools continues to be an ever-present and challenging activity in medical education. This paper describes one school's experiences with specific curricular innovations that were developed or adapted and targeted to meet a clear set of curricular goals during the curriculum reform process. Those goals included: (a) promoting active learning and learner engagement; (b) establishing early professional identity; and (c) developing physician competencies in an integrated and contextual manner while allowing for individualized learning experiences for the millennial student. Six specific innovations championed by the school are described in detail. These included Themes in Medical Education, Translational Pillars, Stony Brook Teaching Families, Transition Courses, Educational Continuous Quality Improvement Processes, and our Career Advising Program. Development of the ideas and design of the innovations were done by faculty and student teams. We discuss successes and ongoing challenges with these innovations which are currently in the fourth year of implementation. Our curriculum reform has emphasized the iterative process of curriculum building. Based on our experience, we discuss general and practical guidelines for curriculum innovation in its three phases: setting the stage, implementation, and monitoring for the achievement of intended goals.

To examine providers' perspectives on the care environment and patient-centered care (PCC) through the eyes of the veteran patient, using guided tours qualitative methodology. Environmental factors, such as attractiveness and function, have the potential to improve patients' experiences. Participatory qualitative methods allow researchers to explore the environment and facilitate discussion. Guided tours were conducted with 25 health care providers/employees at two Veterans Affairs (VA) health care facilities. In guided tours, participants lead the researcher through an environment, commenting on their surroundings, thoughts, and feelings. The researcher walks along with the participant, asking open-ended questions as needed to foster discussion and gain an understanding of the participant's view. Participants were asked to walk through the facility as though they were a veteran. Tours were audio recorded, with participant permission, and transcribed verbatim by research assistants. Three qualitative researchers were responsible for codebook development and coding transcripts and used data-driven coding approaches. Participants discussed physical appearance of the environment and how that influences perceptions about care. Overall, participants highlighted the need to shed the "institutional" appearance. Differences between VA and non-VA health care facilities were discussed, including availability of private rooms and staff to assist with navigating the facility. They reviewed resources in the facility, such as the information desk to assist patients and families. Finally, they offered suggestions for future improvements, including improvements to waiting areas and quiet areas for patients to relax and "get away" from their rooms. Participants highlighted many small changes to the care environment that could enhance the patient experience. Additionally, they examined the environment from the patient's perspective, to identify elements that enhance, or detract from, the patient's care experience. © The Author(s) 2015.

Geriatric education is an important component of the dental hygiene curriculum because, in it, students acquire skills and attitudes to help provide quality care to older adults. The purpose of this study was to determine if off-site exposure to nursing home residents with supervised oversight had the potential to improve dental hygiene students' attitudes toward older adults. Senior dental hygiene students at one school completed a pre-nursing home experience questionnaire. A series of geriatric lectures and discussions, which included discussions about students' anxieties of working with institutionalized older adults, were held prior to the nursing home experience. The students then participated in two supervised four-hour nursing home experiences, were debriefed after the experiences, and completed a second questionnaire. Of thirty-nine potential participants in the study, thirty-two took part in the pre-nursing home experience questionnaire (82.1 percent). They had a mean split Fabroni score of 34.2 (95 percent confidence interval: 32.2, 36.3). The thirty participants in the post-experience questionnaire (76.9 percent of total) had a mean split score of 32.7 (95 percent confidence interval: 30.1, 35.3). This study failed to reject the null hypothesis of no mean difference between the pre- and post-nursing home experience; however, the post-experience mean score was lower than the pre-nursing home experience mean score, indicating a more positive attitude toward older adults after the experience.

1995-01-01

A study of various aspects of Adjustable Speed Drives (ASD) is presented. A summary of the relative merits of different ASD systems presently in vogue is discussed. The advantages of using microcomputer based ASDs is now widely understood and accepted. Of the three most popular drive systems, namely the Induction Motor Drive, Switched Reluctance Motor Drive and Brushless DC Motor Drive, any one may be chosen. The choice would depend on the nature of the application and its requirements. The suitability of the above mentioned drive systems for a photovoltaic array driven ASD for an aerospace application are discussed. The discussion is based on the experience of the authors, various researchers and industry. In chapter 2 a PV array power supply scheme has been proposed, this scheme will have an enhanced reliability in addition to the other known advantages of the case where a stand alone PV array is feeding the heat pump. In chapter 3 the results of computer simulation of PV array driven induction motor drive system have been included. A discussion on these preliminary simulation results have also been included in this chapter. Chapter 4 includes a brief discussion on various control techniques for three phase induction motors. A discussion on different power devices and their various performance characteristics is given in Chapter 5.

Silicon carbide is one of the promising materials for the fabrication of various one- and two-dimensional nanostructures. In this chapter, we discuss experimental and theoretical studies of the plasma-enabled fabrication of silicon carbide quantum dots, nanowires, and nanorods. The discussed fabrication methods include plasma-assisted growth with and without anodic aluminium oxide membranes and with or without silane as a source of silicon. In the silane-free experiments, quartz was used as a source of silicon to synthesize the silicon carbide nanostructures in an environmentally friendly process. The mechanism of the formation of nanowires and nanorods is also discussed.

To discuss the representation and organization of information describing persons' lived experience of health from a personal factors perspective in the light of the International Classification of Functioning, Disability and Health, using spinal cord injury as a case in point for disability. The scientific literature was reviewed, discussion rounds conducted, and qualitative secondary analyses of data carried out using an iterative inductive-deductive approach. Conceptual considerations are explicated that distinguish the personal factors perspective from other components of the International Classification of Functioning, Disability and Health. A representation structure is developed that organizes health-related concepts describing the internal context of functioning. Concepts are organized as individual facts, subjective experiences, and recurrent patterns of experience and behavior specifying 7 areas and 211 concept groups. The article calls for further scientific debate on the perspective of personal factors in the light of the International Classification of Functioning, Disability and Health. A structure that organizes concepts in relation to a personal factors perspective can enhance the comprehensiveness, transparency and standardization of health information, and contribute to the empowerment of persons with disabilities. Implications for rehabilitation The present study collected data from scientific literature reviews, discussion rounds and qualitative secondary analyses in order to develop a representation and organization of information describing persons' lived experience of health from a personal factors perspective in the light of the International Classification of Functioning, Disability and Health. The following representation structure for health-related information from a personal factors perspective was developed: (i) Individuals facts (i.e., socio-demographical factors, position in the immediate social and physical context, personal history and biography), (ii) subjective experience (i.e., feelings, thoughts and beliefs, motives), and (iii) recurrent patterns of experience (i.e., feelings, thoughts and beliefs) and behavior. With this study, we aim to stimulate further scientific discussion about the personal factors component in the International Classification of Functioning, Disability and Health, including its application and subsequent validation for potential implementation into clinical practice.

Effect of time span and task load on pilot mental workload

Berg, S. L.; Sheridan, T. B.

1985-01-01

Two sets of experiments were run to examine how the mental workload of a pilot might be measured. The effects of continuous manual control activity versus discrete assigned mental tasks (including the length of time between receiving an assignment and executing it) were examined. The first experiment evaluated the strengths and weaknesses of measuring mental workload with an objective perforamance (altitude deviations) and five subjective ratings (activity level, complexity, difficulty, stress, and workload). The second set of experiments built upon the first set by increasing workload intensities and adding another performance measure: airspeed deviation. The results are discussed for both low and high experience pilots.

Although they look as common optical components at first glance, their behaviour remains somewhat mysterious since they apparently exhibit stand-alone particle-like features, and then wave-like characteristics when inserted into a Mach-Zehnder interferometer. In this communication are examined and discussed some basic properties of these beamssplitters, both from a classical optics and quantum physics point of view. Herein the most evident convergences and contradictions are highlighted, and the results of a few emblematic experiments demonstrating photon existence are discussed. Alternative empirical models are also proposed in order to shed light on some remaining issues.

The confrontation between general relativity and experiment

Experiments that test the foundations of gravitation theory in terms of the Einstein equivalence principle are discussed along with solar system tests of general relativity at the post-Newtonian level. These include classical (light-deflection, time delay and perihelion shift) tests as well as tests of the strong equivalence principle. The binary pulsar is discussed as an extra-solar-system gravitational testing ground, and attention is given to the multipolarity of the waves and the amount of radiation damping. The mass function, periastron shift, redshift-Doppler parameter and rate of change of the orbit period (Pb) of the binary pulsar are also considered, and it is suggested that the measurement of Pb represents the first observation of the effects of gravitational radiation.

This technical report records and discusses the Second Workshop on Sustainable Software for Science: Practice and Experiences (WSSSPE2). The report includes a description of the alternative, experimental submission and review process, two workshop keynote presentations, a series of lightning talks, a discussion on sustainability, and five discussions from the topic areas of exploring sustainability; software development experiences; credit & incentives; reproducibility & reuse & sharing; and code testing & code review. For each topic, the report includes a list of tangible actions that were proposed and that would lead to potential change. The workshop recognized that reliance on scientific software is pervasive in all areas of world-leading research today. The workshop participants then proceeded to explore different perspectives on the concept of sustainability. Key enablers and barriers of sustainable scientific software were identified from their experiences. In addition, recommendations with new requirements such as software credit files and software prize frameworks were outlined for improving practices in sustainable software engineering. There was also broad consensus that formal training in software development or engineering was rare among the practitioners. Significant strides need to be made in building a sense of community via training in software and technical practices, on increasing their size and scope, and on better integrating them directly into graduate education programs. Finally, journals can define and publish policies to improve reproducibility, whereas reviewers can insist that authors provide sufficient information and access to data and software to allow them reproduce the results in the paper. Hence a list of criteria is compiled for journals to provide to reviewers so as to make it easier to review software submitted for publication as a "Software Paper."

Improving communication training for primary palliative care using a required palliative care rotation for internal medicine (IM) residents has not been assessed. To assess skills acquisition and acceptability for IM residents not selecting an elective. A consecutive, single-arm cohort underwent preobjective structured clinical examination (OSCE) with learner-centric feedback, two weeks of clinical experience, and finally a post-OSCE to crystallize learner-centric take home points. IM second year residents from Dartmouth-Hitchcock were exposed to a required experiential palliative care rotation. Pre- and post-OSCE using a standardized score card for behavioral skills, including patient-centered interviewing, discussing goals of care/code status, and responding to emotion, as well as a confidential mixed qualitative and quantitative evaluation of the experience. Twelve residents were included in the educational program (two were excluded because of shortened experiences) and showed statistically significant improvements in overall communication and more specifically in discussing code status and responding to emotions. General patient-centered interviewing skills were not significantly improved, but prerotation scores reflected pre-existing competency in this domain. Residents viewed the observed simulated clinical experience (OSCE) and required rotation as positive experiences, but wished for more opportunities to practice communication skills in real clinical encounters. A required palliative care experiential rotation flanked by OSCEs at our institution improved the acquisition of primary palliative care communication skills similarly to other nonclinical educational platforms, but may better meet the needs of the resident and faculty as well as address all required ACGME milestones.
