Hitting the Reset Button: Using Formative Assessment to Guide Instruction

ERIC Educational Resources Information Center

Dirksen, Debra J.

2011-01-01

Using formative assessment gives students a second chance to learn material they didn't master the first time around. It lets failure become a learning experience rather than something to fear. Several types of formative assessment are discussed, including how to use summative assessments formatively. (Contains 2 figures.)

Development and Validation of the Caring Loneliness Scale.

PubMed

Karhe, Liisa; Kaunonen, Marja; Koivisto, Anna-Maija

2016-12-01

The Caring Loneliness Scale (CARLOS) includes 5 categories derived from earlier qualitative research. This article assesses the reliability and construct validity of a scale designed to measure patient experiences of loneliness in a professional caring relationship. Statistical analysis with 4 different sample sizes included Cronbach's alpha and exploratory factor analysis with principal axis factoring extraction. The sample size of 250 gave the most useful and comprehensible structure, but all 4 samples yielded underlying content of loneliness experiences. The initial 5 categories were reduced to 4 factors with 24 items and Cronbach's alpha ranging from .77 to .90. The findings support the reliability and validity of CARLOS for the assessment of Finnish breast cancer and heart surgery patients' experiences but as all instruments, further validation is needed.

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

To compare student academic performance and the student experience in the first-year doctor of pharmacy (PharmD) program between the main and newly opened satellite campuses of the University of Maryland. Student performance indicators including graded assessments, course averages, cumulative first-year grade point average (GPA), and introductory pharmacy practice experience (IPPE) evaluations were analyzed retrospectively. Student experience indicators were obtained via an online survey instrument and included involvement in student organizations; time-budgeting practices; and stress levels and their perceived effect on performance. Graded assessments, course averages, GPA, and IPPE evaluations were indistinguishable between campuses. Students' time allocation was not different between campuses, except for time spent attending class and watching lecture videos. There was no difference between students' stress levels at each campus. The implementation of a satellite campus to expand pharmacy education yielded academic performance and student engagement comparable to those from traditional delivery methods.

Does Assessing Suicidality Frequently and Repeatedly Cause Harm? A Randomized Control Study

2015-01-01

Assessing suicidality is common in mental health practice and is fundamental to suicide research. Although necessary, there is significant concern that such assessments have unintended harmful consequences. Using a longitudinal randomized control design, we evaluated whether repeated and frequent assessments of suicide-related thoughts and behaviors negatively affected individuals, including those at-risk for suicide-related outcomes. Adults (N = 282), including many diagnosed with Borderline Personality Disorder (BPD), were recruited through psychiatric outpatient clinics and from the community at large, and were randomly assigned to assessment groups. A Control Assessment group responded to questions regarding negative psychological experiences several times each day during a 2-week Main Observation phase. During the same observation period, an Intensive Suicide Assessment group responded to the same questions, along with questions regarding suicidal behavior and ideation. Negative psychological outcomes were measured during the Main Observation phase (for BPD symptoms unrelated to suicide and for BPD-relevant emotions) and/or at the end of each week during the Main Observation phase and monthly for 6 months thereafter (for all outcomes, including suicidal ideation and behavior). Results revealed little evidence that intensive suicide assessment triggered negative outcomes, including suicidal ideation or behavior, even among people with BPD. A handful of effects did reach or approach significance, though these were temporary and non-robust. However, given the seriousness of some outcomes, we recommend that researchers or clinicians who implement experience sampling methods including suicide-related items carefully consider the benefits of asking about suicide and to inform participants about possible risks.

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

PubMed

Delsignore, Aba

2008-08-01

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

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

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

Human Reliability Assessments: Using the Past (Shuttle) to Predict the Future (ORION)

NASA Technical Reports Server (NTRS)

Mott, Diana L.; Bigler, Mark A.

2017-01-01

NASA uses two HRA assessment methodologies. The first is a simplified method which is based on how much time is available to complete the action, with consideration included for environmental and personal factors that could influence the human's reliability. This method is expected to provide a conservative value or placeholder as a preliminary estimate. This preliminary estimate is used to determine which placeholder needs a more detailed assessment. The second methodology is used to develop a more detailed human reliability assessment on the performance of critical human actions. This assessment needs to consider more than the time available, this would include factors such as: the importance of the action, the context, environmental factors, potential human stresses, previous experience, training, physical design interfaces, available procedures/checklists and internal human stresses. The more detailed assessment is still expected to be more realistic than that based primarily on time available. When performing an HRA on a system or process that has an operational history, we have information specific to the task based on this history and experience. In the case of a PRA model that is based on a new design and has no operational history, providing a "reasonable" assessment of potential crew actions becomes more problematic. In order to determine what is expected of future operational parameters, the experience from individuals who had relevant experience and were familiar with the system and process previously implemented by NASA was used to provide the "best" available data. Personnel from Flight Operations, Flight Directors, Launch Test Directors, Control Room Console Operators and Astronauts were all interviewed to provide a comprehensive picture of previous NASA operations. Verification of the assumptions and expectations expressed in the assessments will be needed when the procedures, flight rules and operational requirements are developed and then finalized.

validated questionnaire assessment of fathers' experiences during childbirth is lacking in routine clinical practice. Salmon's Item List is a short, validated method used for the assessment of birth experience in mothers in both English- and German-speaking communities. With little to no validated data available for fathers, this pilot study aimed to assess the applicability of the German version of Salmon's Item List, including a multidimensional birth experience concept, in fathers. longitudinal study. Data were collected by questionnaires. University hospital in Germany. the birth experiences of 102 fathers were assessed four to six weeks post partum using the German version of Salmon's Item List. construct validity testing with exploratory factor analysis using principal component analysis with varimax rotation was performed to identify the dimensions of childbirth experiences. Internal consistency was also analysed. factor analysis yielded a four-factor solution comprising 17 items that accounted for 54.5% of the variance. The main domain was 'fulfilment', and the secondary domains were 'emotional distress', 'physical discomfort' and 'emotional adaption'. For fulfilment, Cronbach's α met conventional reliability standards (0.87). Salmon's Item List is an appropriate instrument to assess birth experience in fathers in terms of fulfilment. Larger samples need to be examined in order to prove the stability of the factor structure before this can be extended to routine clinical assessment. a reduced version of Salmon's Item List may be useful as a screening tool for general assessment.

National Institutes of Health Pathways to Prevention Workshop: Methods for Evaluating Natural Experiments in Obesity.

PubMed

Emmons, Karen M; Doubeni, Chyke A; Fernandez, Maria E; Miglioretti, Diana L; Samet, Jonathan M

2018-06-05

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

2018-03-01

Psychotic experiences are associated with a number of poor clinical outcomes, including multimorbid psychopathology, suicidal behavior, and poor treatment response. We wished to investigate the relationship between psychotic experiences and disability, including the following domains: cognition, mobility, self-care, social interaction, role functioning, and days out of role. We used three nationally representative and racially/ethnically diverse samples of the general US adult population: the National Comorbidity Survey Replication (NCS-R), the National Latino and Asian American Survey (NLAAS), and the National Survey of American Life (NSAL). Multi-variable logistic regression analyses were used to assess the associations between lifetime psychotic experiences (visual and auditory hallucinatory experiences and delusional ideation; WHO Composite International Diagnostic Interview psychosis screen) and 30-day impairments in functioning across disability domains (using the WHO Disability Assessment Schedule II). In all three samples, models were adjusted for socio-demographics and co-occurring psychiatric disorders. In the NCS-R, models were also adjusted for chronic health conditions. Across all three studies, our adjusted models showed that people with disability had anywhere from about 1.5 to over 3 times the odds of reporting lifetime psychotic experiences, depending on the domain. This was true for each disability domain, except self-care in the NLAAS and in the NSAL. Psychotic experiences are markers of risk for disability across a wide range of domains. This may explain the elevated rates of service utilization among individuals who report psychotic experiences and supports the need to assess for and respond to psychotic experiences even in the absence of psychotic disorder.

2018-05-18

Providing safe and realistic virtual simulations could be an effective way to facilitate the transition from the classroom to clinical practice. As nursing programs begin to include virtual simulations as a learning strategy; it is critical to first assess the technology for ease of use and usefulness. A virtual gaming simulation was developed, and a usability study was conducted to assess its ease of use and usefulness for students and faculty. The Technology Acceptance Model provided the framework for the study, which included expert review and testing by nursing faculty and nursing students. This study highlighted the importance of assessing ease of use and usefulness in a virtual game simulation and provided feedback for the development of an effective virtual gaming simulation. The study participants said the virtual gaming simulation was engaging, realistic and similar to a clinical experience. Participants found the game easy to use and useful. Testing provided the development team with ideas to improve the user interface. The usability methodology provided is a replicable approach to testing virtual experiences before a research study or before implementing virtual experiences into curriculum.

Internalised HIV-stigma, loneliness, depressive symptoms and sleep quality in people living with HIV.

PubMed

Fekete, Erin M; Williams, Stacey L; Skinta, Matthew D

2018-03-01

People living with HIV (PLWH) commonly report sleep disturbances which are associated with long-term health consequences, including disease progression. PLWH also experience internalised stigma as a result of their HIV status, which can be associated with increased loneliness and depression. Little attention focuses on the impact of these factors on sleep. Therefore, we examined whether internalised HIV-stigma was indirectly related to poorer sleep quality through higher levels of loneliness and depressive symptoms. 181 PLWH from across the United States completed an online survey. Main Study Measures: Internalised HIV-stigma was assessed using the HIV-Stigma Scale, loneliness was assessed using the UCLA-Loneliness Scale-Short Form, depressive symptoms were assessed with the Center for Epidemiologic Studies-Depression Index, and Sleep Quality was assessed using the Pittsburgh Sleep Quality Index. Internalised HIV-stigma was indirectly associated with poorer global sleep quality and daytime sleep dysfunction through both loneliness and depressive symptoms. PLWH who experience HIV-related stigma may experience greater feelings of loneliness, which are related to increased depressive symptoms and poorer sleep quality. Interventions focused on improving sleep in PLWH should focus on multiple factors that influence sleep, including psychosocial factors such as stigma, social isolation and depressive symptoms.

Planning the Unplanned Experiment: Assessing the Efficacy of Standards for Safety Critical Software

Graydon, Patrick J.; Holloway, C. Michael

2015-01-01

We need well-founded means of determining whether software is t for use in safety-critical applications. While software in industries such as aviation has an excellent safety record, the fact that software aws have contributed to deaths illustrates the need for justi ably high con dence in software. It is often argued that software is t for safety-critical use because it conforms to a standard for software in safety-critical systems. But little is known about whether such standards `work.' Reliance upon a standard without knowing whether it works is an experiment; without collecting data to assess the standard, this experiment is unplanned. This paper reports on a workshop intended to explore how standards could practicably be assessed. Planning the Unplanned Experiment: Assessing the Ecacy of Standards for Safety Critical Software (AESSCS) was held on 13 May 2014 in conjunction with the European Dependable Computing Conference (EDCC). We summarize and elaborate on the workshop's discussion of the topic, including both the presented positions and the dialogue that ensued.

Although awareness of the importance of the research capacity of community-based organizations (CBOs) is growing, a uniform framework of the research capacity domains within CBOs has not yet been developed. To develop a framework and instrument (the Community REsearch Activity assessment Tool [CREAT]) for assessing the research activity and capacity of CBOs that incorporates awareness of the different data collection and analysis priorities of CBOs. We conducted a review of existing tools for assessing research capacity to identify key capacity domains. Instrument items were developed through an iterative process with CBO representatives and community researchers. The CREAT was then pilot tested with 30 CBOs. The four primary domains of the CREAT framework include 1) organizational support for research, 2) generalizable experiences, 3) research specific experiences, and 4) funding. Organizations reported a high prevalence of activities in the research-specific experiences domain, including conducting literature reviews (70%), use of research terminology (83%), and primary data collection (100%). Respondents see research findings as important to improve program and service delivery, and to seek funds for new programs and services. Funders, board members, and policymakers are the most important dissemination audiences. The work reported herein advances the field of CBO research capacity by developing a systematic framework for assessing research activity and capacity relevant to the work of CBOs, and by developing and piloting an instrument to assess activity in these domains.

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

PubMed

Munn, Zachary; Jordan, Zoe

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

Women's childbirth experience can have immediate as well as long-term positive or negative effects on their life, well-being and health. When evaluating and drawing conclusions from research results, women's experiences of childbirth should be one aspect to consider. Researchers and clinicians need help in finding and selecting the most suitable instrument for their purpose. The aim of this study was therefore to systematically identify and present validated instruments measuring women's childbirth experience. A systematic review was conducted in January 2016 with a comprehensive search in the bibliographic databases PubMed, CINAHL, Scopus, The Cochrane Library and PsycINFO. Included instruments measured women's childbirth experiences. Papers were assessed independently by two reviewers for inclusion, and quality assessment of included instruments was made by two reviewers independently and in pairs using Terwee et al's criteria for evaluation of psychometric properties. In total 5189 citations were screened, of which 5106 were excluded by title and abstract. Eighty-three full-text papers were reviewed, and 37 papers were excluded, resulting in 46 included papers representing 36 instruments. These instruments demonstrated a wide range in purpose and content as well as in the quality of psychometric properties. This systematic review provides an overview of existing instruments measuring women's childbirth experiences and can support researchers to identify appropriate instruments to be used, and maybe adapted, in their specific contexts and research purpose.

Designing Effective Undergraduate Research Experiences

Severson, S.

2010-12-01

I present a model for designing student research internships that is informed by the best practices of the Center for Adaptive Optics (CfAO) Professional Development Program. The dual strands of the CfAO education program include: the preparation of early-career scientists and engineers in effective teaching; and changing the learning experiences of students (e.g., undergraduate interns) through inquiry-based "teaching laboratories." This paper will focus on the carry-over of these ideas into the design of laboratory research internships such as the CfAO Mainland internship program as well as NSF REU (Research Experiences for Undergraduates) and senior-thesis or "capstone" research programs. Key ideas in maximizing student learning outcomes and generating productive research during internships include: defining explicit content, scientific process, and attitudinal goals for the project; assessment of student prior knowledge and experience, then following up with formative assessment throughout the project; setting reasonable goals with timetables and addressing motivation; and giving students ownership of the research by implementing aspects of the inquiry process within the internship.

Adverse Childhood Experiences and the Mental Health of Veterans.

2015-06-01

Many U.S. Veterans have experienced the burdens of mental illness and suicide. The current article focuses on Veterans who served from 2001-2015. Although combat exposure and suicidal ideation are linked, approximately one half of all suicides among Active Duty service members (who have served since 2001) occurred among those who never deployed. Researchers who sought additional risks for suicide found that Veterans have greater odds of adversities in childhood than the general population. Adverse childhood experiences are stressful and traumatic experiences, including abuse and neglect, as well as witnessing household dysfunction, or growing up with individuals with mental illness or substance abuse. Further, childhood physical abuse has been shown to be a significant predictor for posttraumatic stress disorder and suicide. Adverse childhood experiences confer additional risk for the mental health of service members. Psychiatric nursing implications include the importance of assessing early childhood adversity during psychosocial assessments. Providing trauma-informed strategies for treatment is an essential element of psychiatric nursing care. Copyright 2015, SLACK Incorporated.

Objectives To compare student academic performance and the student experience in the first-year doctor of pharmacy (PharmD) program between the main and newly opened satellite campuses of the University of Maryland. Methods Student performance indicators including graded assessments, course averages, cumulative first-year grade point average (GPA), and introductory pharmacy practice experience (IPPE) evaluations were analyzed retrospectively. Student experience indicators were obtained via an online survey instrument and included involvement in student organizations; time-budgeting practices; and stress levels and their perceived effect on performance. Results Graded assessments, course averages, GPA, and IPPE evaluations were indistinguishable between campuses. Students' time allocation was not different between campuses, except for time spent attending class and watching lecture videos. There was no difference between students' stress levels at each campus. Conclusions The implementation of a satellite campus to expand pharmacy education yielded academic performance and student engagement comparable to those from traditional delivery methods.

The experiments selected for the database are either 2D or axisymmetric, and include both compression corner and impinging type SWTBL interactions. The strength of the interactions range from attached to incipient separation to fully separated flows. The experiments were chosen based on criterion to ensure quality of the datasets, to be relevant to NASA's missions and to be useful for validation and uncertainty assessment of CFD Navier-Stokes predictive methods, both now and in the future. An emphasis on datasets selected was on surface pressures and surface heating throughout the interaction, but include some wall shear stress distributions and flowfield profiles. Included, for selected cases, are example CFD grids and setup information, along with surface pressure and wall heating results from simulations using current NASA real-gas Navier-Stokes codes by which future CFD investigators can compare and evaluate physics modeling improvements and validation and uncertainty assessments of future CFD code developments. The experimental database is presented tabulated in the Appendices describing each experiment. The database is also provided in computer-readable ASCII files located on a companion DVD.

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

Interprofessional care teams are the backbone of intensive care units (ICUs) where severity of illness is high and care requires varied skills and experience. Despite this care model, longitudinal educational programmes for such workplace teams rarely include all professions. In this article, we report findings on the initial assessment and evaluation of an ongoing, longitudinal simulation-based curriculum for interprofessional workplace critical care teams. The study had two independent components, quantitative learner assessment and qualitative curricular evaluation. To assess curriculum effectiveness at meeting learning objectives, participant-reported key learning points identified using a self-assessment tool administered immediately following curricular participation were mapped to session learning objectives. To evaluate the curriculum, we conducted a qualitative study using a phenomenology approach involving purposeful sampling of nine curricular participants undergoing recorded semi-structured interviews. Verbatim transcripts were reviewed by two independent readers to derive themes further subdivided into successes and barriers. Learner self-assessment demonstrated that the majority of learners, across all professions, achieved at least one intended learning objective with senior learners more likely to report team-based objectives and junior learners more likely to report knowledge/practice objectives. Successes identified by curricular evaluation included authentic critical care curricular content, safe learning environment, and team comradery from shared experience. Barriers included unfamiliarity with the simulation environment and clinical coverage for curricular participation. This study suggests that a sustainable interprofessional curriculum for workplace ICU critical care teams can achieve the desired educational impact and effectively deliver authentic simulated work experiences if barriers to educational engagement and participation can be overcome.

Psychotic-like experiences (PLEs) or subclinical psychotic experiences have received increased attention as some studies have suggested continuity between PLEs and psychotic disorders. However, epidemiological and correlational studies of PLEs showed mixed findings - it is observed that different studies use a wide variety of definitions of PLEs, as well as different assessment tools that are designed to capture such described experiences. The differences in definitions and assessment tools adopted could contribute to the discrepancy of findings. The current review aims to examine the definitions and assessment tools adopted in the studies of PLEs. Literature search was conducted between October 2013 and February 2014 using three search engines: Medline, Web of Science and PubMed. A total of 76 papers met the selection criteria and were included in the current review. It is found that the majority of papers reviewed defined PLEs quantitatively using assessment tools and do not have a specific phenomenological definition, whereas assessment tools adopted have a wide variety. Furthermore, phenomenological studies of PLEs were rare. The variations in definitions and assessment tools of PLEs might contribute to mixed findings in researches. Reaching to a consensus through the study of phenomenology of PLEs is essential to further advancement of the research in this area. © 2015 Wiley Publishing Asia Pty Ltd.

Effects of diet and behavior therapy on social and motor behavior of retarded phenylketonuric adults: an experimental analysis.

1978-03-01

The effects of a low phenylalanine diet on six retarded phenylketonuric adults were assessed. An ABA individual-subject design was used in experiment I to assess the effects of a low phenylalanine diet on social and motor behavior. Following a baseline during which the subjects ingested a normal phenylalanine diet (phase A), a low phenylalanine diet (phase B) was administered in a double blind fashion. Finally, the baseline condition (phase A) was reinstated (normal diet). The low phenylalanine diet resulted in few significant behavioral changes for those subjects with which proper methodologic controls were employed. However, for two of six subjects motor behavior, including stereotypy and tremor, seem to have ameliorated. In experiment II, applied behavior analysis techniques, including differential reinforcement of other behavior and time out, were combined to radically reduce the frequency of stereotypy and self-abuse exhibited by one of the six subjects of experiment I.

Take-Home Experiments in Undergraduate Fluid Mechanics Education

NASA Astrophysics Data System (ADS)

Cimbala, John

2007-11-01

Hands-on take-home experiments, assigned as homework, are useful as supplements to traditional in-class demonstrations and laboratories. Students borrow the equipment from the department's equipment room, and perform the experiment either at home or in the student lounge or student shop work area. Advantages include: (1) easy implementation, especially for large classes, (2) low cost and easy duplication of multiple units, (3) no loss of lecture time since the take-home experiment is self-contained with all necessary instructions, and (4) negligible increase in student or teaching assistant work load since the experiment is assigned as a homework problem in place of a traditional pen and paper problem. As an example, a pump flow take-home experiment was developed, implemented, and assessed in our introductory junior-level fluid mechanics course at Penn State. The experimental apparatus consists of a bucket, tape measure, submersible aquarium pump, tubing, measuring cup, and extension cord. We put together twenty sets at a total cost of less than 20 dollars per set. Students connect the tube to the pump outlet, submerge the pump in water, and measure the volume flow rate produced at various outflow elevations. They record and plot volume flow rate as a function of outlet elevation, and compare with predictions based on the manufacturer's pump performance curve (head versus volume flow rate) and flow losses. The homework assignment includes an online pre-test and post-test to assess the change in students' understanding of the principles of pump performance. The results of the assessment support a significant learning gain following the completion of the take-home experiment.

2016-01-01

Medical students have limited exposure to Geriatrics in their traditional training. Service-learning offers students the opportunity to engage with older adult communities and become more comfortable interacting with this population. A preclinical elective course was developed to expand medical students' experiences in Geriatrics through service-learning. In this course, students conducted needs assessments in diverse older adult communities, created health education projects to address community-identified needs, and reflected on their experiences through written assignments and presentations. The course instructor presented lectures on special topics in Geriatrics, including ageism and health literacy. The curriculum aimed to familiarize students with older adults' needs in a variety of settings. Over 3 years, 74 students participated in the service-learning course. Students were assigned to older adult community sites, where they conducted needs assessments and designed and implemented original educational projects targeting community concerns. Program evaluation methods included a validated survey assessing students' attitudes toward older adults, course evaluations, review of student assignments and projects, and feedback from older adult participants and site coordinators. Students gained hands-on experience working with older adults and designing appropriate health education projects. Analysis of attitude surveys demonstrated students' increased interest in Geriatrics as a career. Both students and older adult participants described enjoyable, valuable experiences gained from service-learning activities. Students appreciated the combination of community and classroom learning about Geriatrics. Service-learning was most constructive at sites with responsive coordinators, engaged older adults, and a need for health education resources. The course challenged students to assess health needs in communities that included cognitively impaired elders and to design educational projects tailored to older adults.

To examine the impact of not blinding outcome assessors on estimates of intervention effects in animal experiments modeling human clinical conditions. We searched PubMed, Biosis, Google Scholar, and HighWire Press and included animal model experiments with both blinded and nonblinded outcome assessors. For each experiment, we calculated the ratio of odds ratios (ROR), that is, the odds ratio (OR) from nonblinded assessments relative to the corresponding OR from blinded assessments. We standardized the ORs according to the experimental hypothesis, such that an ROR <1 indicates that nonblinded assessor exaggerated intervention effect, that is, exaggerated benefit in experiments investigating possible benefit or exaggerated harm in experiments investigating possible harm. We pooled RORs with inverse variance random-effects meta-analysis. We included 10 (2,450 animals) experiments in the main meta-analysis. Outcomes were subjective in most experiments. The pooled ROR was 0.41 (95% confidence interval [CI], 0.20, 0.82; I(2) = 75%; P < 0.001), indicating an average exaggeration of the nonblinded ORs by 59%. The heterogeneity was quantitative and caused by three pesticides experiments with very large observer bias, pooled ROR was 0.20 (95% CI, 0.07, 0.59) in contrast to the pooled ROR in the other seven experiments, 0.82 (95% CI, 0.57, 1.17). Lack of blinding of outcome assessors in animal model experiments with subjective outcomes implies a considerable risk of observer bias. Copyright © 2014 Elsevier Inc. All rights reserved.

Benchmarking computational fluid dynamics models of lava flow simulation for hazard assessment, forecasting, and risk management

2017-01-01

Numerical simulations of lava flow emplacement are valuable for assessing lava flow hazards, forecasting active flows, designing flow mitigation measures, interpreting past eruptions, and understanding the controls on lava flow behavior. Existing lava flow models vary in simplifying assumptions, physics, dimensionality, and the degree to which they have been validated against analytical solutions, experiments, and natural observations. In order to assess existing models and guide the development of new codes, we conduct a benchmarking study of computational fluid dynamics (CFD) models for lava flow emplacement, including VolcFlow, OpenFOAM, FLOW-3D, COMSOL, and MOLASSES. We model viscous, cooling, and solidifying flows over horizontal planes, sloping surfaces, and into topographic obstacles. We compare model results to physical observations made during well-controlled analogue and molten basalt experiments, and to analytical theory when available. Overall, the models accurately simulate viscous flow with some variability in flow thickness where flows intersect obstacles. OpenFOAM, COMSOL, and FLOW-3D can each reproduce experimental measurements of cooling viscous flows, and OpenFOAM and FLOW-3D simulations with temperature-dependent rheology match results from molten basalt experiments. We assess the goodness-of-fit of the simulation results and the computational cost. Our results guide the selection of numerical simulation codes for different applications, including inferring emplacement conditions of past lava flows, modeling the temporal evolution of ongoing flows during eruption, and probabilistic assessment of lava flow hazard prior to eruption. Finally, we outline potential experiments and desired key observational data from future flows that would extend existing benchmarking data sets.

Survey Instruments to Assess Patient Experiences With Access and Coordination Across Health Care Settings: Available and Needed Measures.

Improving access can increase the providers a patient sees, and cause coordination challenges. For initiatives that increase care across health care settings, measuring patient experiences with access and care coordination will be crucial. Map existing survey measures of patient experiences with access and care coordination expected to be relevant to patients accessing care across settings. Preliminarily examine whether aspects of access and care coordination important to patients are represented by existing measures. Structured literature review of domains and existing survey measures related to access and care coordination across settings. Survey measures, and preliminary themes from semistructured interviews of 10 patients offered VA-purchased Community Care, were mapped to identified domains. We identified 31 existing survey instruments with 279 items representing 6 access and 5 care coordination domains relevant to cross-system care. Domains frequently assessed by existing measures included follow-up coordination, primary care access, cross-setting coordination, and continuity. Preliminary issues identified in interviews, but not commonly assessed by existing measures included: (1) acceptability of distance to care site given patient's clinical situation; (2) burden on patients to access and coordinate care and billing; (3) provider familiarity with Veteran culture and VA processes. Existing survey instruments assess many aspects of patient experiences with access and care coordination in cross-system care. Systems assessing cross-system care should consider whether patient surveys accurately reflect the level of patients' concerns with burden to access and coordinate care, and adequately reflect the impact of clinical severity and cultural familiarity on patient preferences.

The role of patient experience and its influence on adherence to antidepressant treatment.

Johnston, Brenda J

2013-12-01

Major depression can be a very challenging illness and although antidepressant agents are shown to provide benefit, many patients do not adhere to antidepressant treatment guidelines. Multiple factors contribute to adherence, including the influence of patient experience. The purpose of this article is to conduct a systematic review on the influence of patient experience with depression and antidepressant agents on treatment adherence. Thirteen research articles were selected for the review and revealed that patient past experience with depression and antidepressant agents, vicarious experiences, beliefs and attitudes, and the treatment experience itself can impact adherence. It is important for providers to be vigilant with assessment and include patient experience when developing a plan of care. This approach encourages shared decision making and a patient-centered focus for improved management of depression. Copyright 2013, SLACK Incorporated.

Surgeons play a significant role in the treatment of patients with many types of cancer, including the management of advanced and recurrent disease after long periods of apparent remission. The recently introduced Victorian Voluntary Assisted Dying (VAD) Act represents a shift in paradigm in Australian medical practice. To be eligible for VAD, the new legislation requires patient assessment by a physician with at least 5 years post-fellowship experience and relevant expertise in the patient's condition. Given many specialist surgeons' experience in managing advanced and often incurable malignancy, it is likely that many will receive referrals for assessment for VAD. It is foreseeable that other states and territories in Australia will follow suit with similar legislation. It is imperative that surgeons receiving referrals to assess patients seeking access to VAD are familiar with the legislation and assessment process. This article summarizes the current regulation of VAD in Australia, including the patient application and assessment process, briefly reviews world-wide assisted dying practices and discusses the relevance to surgeons practicing in Australia. © 2018 Royal Australasian College of Surgeons.

To assess the extent to which US colleges and schools of pharmacy are incorporating interprofessional education into their introductory pharmacy practice experiences (IPPEs), and to identify barriers to implementation; characterize the format, structure, and assessment; and identify factors associated with incorporating interprofessional education in IPPEs. An electronic survey of 116 US colleges and schools of pharmacy was conducted from March 2011 through May 2011. Interprofessional education is a stated curricular goal in 78% of colleges and schools and consistently occurred in IPPEs in 55%. Most colleges and schools that included interprofessional education in IPPEs (70%) used subjective measures to assess competencies, while 17.5% used standardized outcomes assessment instruments. Barriers cited by respondents from colleges and schools that had not implemented interprofessional education in IPPEs included a lack of access to sufficient healthcare facilities with interprofessional education opportunities (57%) and a lack of required personnel resources (52%). Many US colleges and schools of pharmacy have incorporated interprofessional education into their IPPEs, but there is a need for further expansion of interprofessional education and better assessment related to achievement of interprofessional education competencies in IPPEs.

We investigated the relation between déjà vu and dissociative experiences in nonclinical subjects. In 227 adult volunteers, déjà vu and dissociative experiences were evaluated by means of the inventory of déjà vu experiences assessment and dissociative experiences scale (DES). Déjà vu experiences occurred in 162 (71.4%) individuals. In univariate correlation analysis, the frequency of déjà vu experiences, as well as 5 other inventory of déjà vu experiences assessment symptoms and age at the time of evaluation, correlated significantly with the DES score. After exclusion of intercorrelative effects using multiple regression analysis, déjà vu experiences did not remain in the model. The DES score was best correlated with a model that included age, jamais vu, depersonalization, and precognitive dreams. Two indices for pathological dissociation (DES-taxon and DES > or = 30) were not associated with déjà vu experiences. Our findings suggest that déjà vu experiences are unlikely to be core pathological dissociative experiences.

One of the challenges in the numerical weather models is the adequate representation of soil-vegetation-atmosphere interaction at different spatial scales, including scenarios with heterogeneous land cover and complex mountainous terrain. The interaction determines the energy, mass and momentum exchange at the surface and could affect different variables including precipitation, temperature and wind. In order to quantify the long-term climate impact of changes in local land use and to assess the role of topography, two numerical experiments were examined. The first experiment allows assessing the continuous growth of urban areas within the Aburrá Valley, a complex terrain region located in Colombian Andes. The Weather Research Forecast model (WRF) is used as the basis of the experiment. The basic setup involves two nested domains, one representing the continental scale (18 km) and the other the regional scale (2 km). The second experiment allows drastic topography modification, including changing the valley configuration to a plateau. The control run for both experiments corresponds to a climatological scenario. In both experiments the boundary conditions correspond to the climatological continental domain output. Surface temperature, surface winds and precipitation are used as the main variables to compare both experiments relative to the control run. The results of the first experiment show a strong relationship between land cover and the variables, specially for surface temperature and wind speed, due to the strong forcing land cover imposes on the albedo, heat capacity and surface roughness, changing temperature and wind speed magnitudes. The second experiment removes the winds spatial variability related with hill slopes, the direction and magnitude are modulated only by the trade winds and roughness of land cover.

Human Reliability Assessments: Using the Past (Shuttle) to Predict the Future (Orion)

NASA (National Aeronautics and Space Administration) Johnson Space Center (JSC) Safety and Mission Assurance (S&MA) uses two human reliability analysis (HRA) methodologies. The first is a simplified method which is based on how much time is available to complete the action, with consideration included for environmental and personal factors that could influence the human's reliability. This method is expected to provide a conservative value or placeholder as a preliminary estimate. This preliminary estimate or screening value is used to determine which placeholder needs a more detailed assessment. The second methodology is used to develop a more detailed human reliability assessment on the performance of critical human actions. This assessment needs to consider more than the time available, this would include factors such as: the importance of the action, the context, environmental factors, potential human stresses, previous experience, training, physical design interfaces, available procedures/checklists and internal human stresses. The more detailed assessment is expected to be more realistic than that based primarily on time available. When performing an HRA on a system or process that has an operational history, we have information specific to the task based on this history and experience. In the case of a Probabilistic Risk Assessment (PRA) that is based on a new design and has no operational history, providing a "reasonable" assessment of potential crew actions becomes more challenging. To determine what is expected of future operational parameters, the experience from individuals who had relevant experience and were familiar with the system and process previously implemented by NASA was used to provide the "best" available data. Personnel from Flight Operations, Flight Directors, Launch Test Directors, Control Room Console Operators, and Astronauts were all interviewed to provide a comprehensive picture of previous NASA operations. Verification of the assumptions and expectations expressed in the assessments will be needed when the procedures, flight rules, and operational requirements are developed and then finalized.

Graduate medical education (GME) programs may struggle to provide the knowledge, skills, and experiences necessary to meet trainee career interests and goals beyond a clinical focus. Sponsoring institutions can partner with programs to deliver content not included in typical clinical experiences of GME programs. To perform a needs assessment and to develop, implement, and measure acceptability and feasibility of an institution-wide GME Concentrations curriculum. In response to the needs assessment, GME leadership developed 4 concentrations: (1) Resident-as-Teacher; (2) Patient Safety and Quality Improvement; (3) Law, Ethics, and Health Policy; and (4) Leaders in Medicine. We formed advisory committees that developed curricula for each concentration, including didactics, experiential learning, and individual project mentoring. Participants completed pre- and postassessments. We assessed feasibility and evaluated participant presentations and final projects. Over the course of 3 years, 91 trainees (of approximately 1000 trainees each year) from 36 GME programs (of 82 accredited programs) have participated in the program. The number of participants has increased each year, and 22 participants have completed the program overall. Cost for each participant is estimated at $500. Participant projects addressed a variety of education and health care areas, including curriculum development, quality improvement, and national needs assessments. Participants reported that their GME Concentrations experience enhanced their training and fostered career interests. The GME Concentrations program provides a feasible, institutionally based approach for educating trainees in additional interest areas. Institutional resources are leveraged to provide and customize content important to participants' career interests beyond their specialty.

Practitioners' experiences of adolescent suicidal behaviour in peer groups.

PubMed

Briggs, S; Slater, T; Bowley, J

2017-06-01

WHAT IS KNOWN ON THE SUBJECT?: Group suicidal behaviour can be devastating for all concerned. There is an absence of research on adolescent suicidal group behaviour. The perspectives of practitioners' experiences of these groups are largely lacking from research literature. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Practitioners work regularly with suicidal behaviour in adolescent peer groups. Practitioners identify peer relationships in groups as complex, including elements that are both suicide encouraging and preventing. Practitioners identify a range of ways in which young people become involved in suicidal behaviour in groups, including indirectly through risk taking and care-seeking as well as directly suicidal or self-harming. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Assessments of young people should routinely include a focus on the qualities of peer relations, including those in the online/digital realm. Assessments and interventions need to consider the complexity of group relationships and roles, and the multiplicity of factors that can contribute to suicidal behaviour in groups. Interventions that sustain therapeutic connectedness are helpful for taking dynamic/fluctuating risks into account. Introduction Group suicidal behaviour by young people can have harmful effects; it may be increasing, influenced by online media and reported increasing self-harm rates; new knowledge and understanding to inform interventions is required. Aim To explore how practitioners experience group suicidal behaviour amongst adolescents, how they assess risks/needs, and how these insights inform understanding about these groups. Method Ten practitioners, including Mental Health Nurses, were interviewed in one multidisciplinary CAMHS, in England. Data analysis was by Thematic Analysis (Braun & Clarke 2006). Results Participants described frequently working with suicidal groups. Roles in groups include suicide encouraging and preventing. Practitioners identify risky and protective connections between young people, online and offline. Clinical tensions include living with suicidal risks, emotional and positional challenges, and getting to grips with digital media. Discussion Peer groups appear to have a larger role in adolescent suicide than recognized to date. Practitioners need to assess young people's roles in groups, their diverse motivations and to understand constantly changing digital media. Implications for practice Assessments of suicide risk for young people should routinely include focus on peer relations including the online/digital realm. Maintaining relationships with vulnerable young people facilitates managing fluctuating risks and understanding different group dynamics. © 2017 John Wiley & Sons Ltd.

Assessing the effect of adding interactive modeling to the geoscience curriculum

Technology and computer models enhance the learning experience when appropriately utilized. Moreover, learning is significantly improved when effective visualization is combined with models of processes allowing for inquiry-based problem solving. Still, hands-on experiences in real scenarios result in better contextualization of related problems compared to virtual laboratories. Therefore, the role of scientific visualization, technology, and computer modeling is to enhance, not displace, the learning experience by supplementing real-world problem solving and experiences, although in some circumstances, they can adequately serve to take the place of reality. The key to improving scientific education is to embrace an inquiry-based approach that favorably uses technology. This study will attempt to evaluate the effect of adding interactive modeling to the geological sciences curriculum. An assessment tool, designed to assess student understanding of physical hydrology, was used to evaluate a curriculum intervention based on student learning with a data- and modeling-driven approach using COMSOL Multiphysics software. This intervention was implemented in an upper division and graduate physical hydrology course in fall 2012. Students enrolled in the course in fall 2011 served as the control group. Interactive modeling was added to the curriculum in fall 2012 to replace the analogous mathematical modeling done by hand in fall 2011. Pre- and post-test results were used to assess and report its effectiveness. Student interviews were also used to probe student reactions to both the experimental and control curricula. The pre- and post-tests asked students to describe the significant processes in the hydrological cycle and describe the laws governing these processes. Their ability to apply their knowledge in a real-world problem was also assessed. Since the pre- and post-test data failed to meet the assumption of normality, a non-parametric Kruskal-Wallis test was run to determine if there were differences in pre- and post-test scores among the 2011 and 2012 groups. Results reveal significant differences in pretest and posttest scores among the 2011 and 2012 groups. Interview data revealed that students experience both affordances and barriers to using geoscience learning tools. Important affordances included COMSOL's modeling capabilities, the visualizations it offers, as well as the opportunity to use the software in the course. Barriers included lack of COMSOL experience, difficulty with COMSOL instructions, and lack of instruction with the software. Results from this study revealed that a well-designed pre- and post-assessment can be used to infer whether a given instructional intervention has caused a change in understanding in a given group of students, but the results are not necessarily generalizable. However, the student interviews, which were used to probe student reactions to both the experimental and control curricula, revealed that students experience both affordances and barriers to geoscience learning tools. This result has limitations including the number of participants, all from one institution, but the assessment tool was useful to assess the effect of adding interactive modeling to the geoscience curriculum.

2015-12-01

To evaluate the accuracy of different methods used to identify individuals with increased risk of developing dental coronal caries. Studies on following methods were included: previous caries experience, tests using microbiota, buffering capacity, salivary flow rate, oral hygiene, dietary habits and sociodemographic variables. QUADAS-2 was used to assess risk of bias. Sensitivity, specificity, predictive values, and likelihood ratios (LR) were calculated. Quality of evidence based on ≥3 studies of a method was rated according to GRADE. PubMed, Cochrane Library, Web of Science and reference lists of included publications were searched up to January 2015. From 5776 identified articles, 18 were included. Assessment of study quality identified methodological limitations concerning study design, test technology and reporting. No study presented low risk of bias in all domains. Three or more studies were found only for previous caries experience and salivary mutans streptococci and quality of evidence for these methods was low. Evidence regarding other methods was lacking. For previous caries experience, sensitivity ranged between 0.21 and 0.94 and specificity between 0.20 and 1. Tests using salivary mutans streptococci resulted in low sensitivity and high specificity. For children with primary teeth at baseline, pooled LR for a positive test was 3 for previous caries experience and 4 for salivary mutans streptococci, given a threshold ≥10(5) CFU/ml. Evidence on the validity of analysed methods used for caries risk assessment is limited. As methodological quality was low, there is a need to improve study design. Low validity for the analysed methods may lead to patients with increased risk not being identified, whereas some are falsely identified as being at risk. As caries risk assessment guides individualized decisions on interventions and intervals for patient recall, improved performance based on best evidence is greatly needed.

Parenting experiences of living with a child with attention deficit hyperactivity disorder: a systematic review of qualitative evidence.

PubMed

Laugesen, Britt; Groenkjaer, Mette

2015-11-01

Attention deficit hyperactivity disorder is the most prevalent mental disorder among children and adolescents worldwide. Parenting a child with attention deficit hyperactivity disorder is challenging and parents find it difficult to raise the child and struggle to get professional support. Research has shown how living with a child with Attention Deficit Hyperactivity Disorder influences the families' daily life. This includes how the parents manage to maintain a bearable family life, supportive or not supportive factors as well as parents' experiences of collaboration with professionals in diverse settings. The objective of this systematic review was to identify and synthesize the best available evidence on parenting experiences of living with a child with attention deficit hyperactivity disorder, including their experiences of health care and other services. This review considered research articles with qualitative data examining the experiences of parents of children with attention deficit hyperactivity disorder. The phenomena of interest were parenting experiences of living with a child with attention deficit hyperactivity disorder, including their experiences of health care and other services, and collaboration with professionals. Retrospective and prospective searches were conducted in MedNar, ProQuest Dissertations and Theses, PubMed, Embase, PsycINFO and CINAHL. The reference lists of the included research articles were searched for additional studies, and a search for cited citations in Web of Science was conducted. Two independent reviewers assessed articles selected for retrieval for methodological validity prior to inclusion in the review using the standardized critical appraisal instrument from the Joanna Briggs Institute, the Qualitative Assessment and Review Instrument. Data were extracted from research articles included in the review using the standardized data extraction tool from the Qualitative Assessment and Review Instrument. Qualitative research findings were pooled using the Qualitative Assessment and Review Instrument. This involved aggregation and synthesis of findings. A total of 21 research articles were included in the review. The review process resulted in 129 study findings that were aggregated into 15 categories. The categories generated six synthesized findings: 1) An emotional roller coaster between hope and hopelessness, 2) Mothers as advocates in a battlefield within the system and family, 3) Parental experiences in a crossfire of blame, self-blame and stigmatization, 4) Shuttling between supportive and non-supportive services and professionals, 5) Routines, structures and strategies within everyday life, and 6) Despite multiple challenges, it is not all bad. The findings illustrate the complexity of parental experiences that are influenced by guilt, hope, blame, stigmatization, exhaustion, reconciliation and professional collaboration. The findings address the impact attention deficit hyperactivity disorder has on the everyday family, and how parents seem to adapt to their life situation in the process of accepting their child's disorder. Health care systems and other professionals need to provide support and understanding to families of children with ADHD. Further research is needed to examine how professionals in health care settings can address the individual needs of the families and how future interventions may support the families and improve competences of health professionals.

The purpose of this study was to develop a valid measure for assessing clinical teaching effectiveness within the field of physical therapy. The Clinical Teaching Effectiveness Questionnaire (CTEQ) was developed via a 4-stage process, including (1) initial content development, (2) content analysis with 8 clinical instructors with over 5 years of clinical teaching experience, (3) pilot testing with 205 clinical instructors from 2 universities in the Northeast of the United States, and (4) psychometric evaluation, including principal component analysis. The scale development process resulted in a 30-item questionnaire with 4 sections that relate to clinical teaching: learning experiences, learning environment, communication, and evaluation. The CTEQ provides a preliminary valid measure for assessing clinical teaching effectiveness in physical therapy practice.

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

PubMed

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

2017-06-01

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

Intimate partner violence and psychotic experiences in four U.S. cities.

2018-05-01

A large body of research has established a relationship between trauma exposure, particularly during childhood, and psychotic experiences. Yet, there remains a general lack of research on adult trauma exposure, including intimate partner violence (IPV), as a risk factor for psychotic experiences. The purpose of this study is to investigate the association between IPV and psychotic experiences in U.S. cities. Data were collected from 1615 participants in four U.S. cities. Psychotic experiences were assessed through the World Health Organization (WHO) Composite International Diagnostic Interview (CIDI) psychosis screen along with adapted IPV measures. Findings revealed that experiencing at least one form of IPV was significantly associated with each of the four psychotic experiences assessed for both men and women. The strongest associations were found for threatening and sexual IPV; physical IPV was not significantly associated with psychotic experiences. Exposure to IPV was associated with more than a tripling of the odds of reporting at least one psychotic experience as opposed to none. Among those exposed to IPV there was between three- to five times the odds of reporting specific subtypes of psychotic experiences. The results expand on prior findings linking psychotic experiences and childhood trauma exposure to include intimate adult exposures. Emotional and sexual IPV appear to be associated with elevated risk for psychotic experiences in adulthood. Even though IPV is more commonly reported by women in the U.S., such victimization appears to have similar associations with psychotic experiences regardless of gender. Copyright © 2017 Elsevier B.V.

A global experimental dataset for assessing grain legume production

PubMed Central

Cernay, Charles; Pelzer, Elise; Makowski, David

2016-01-01

Grain legume crops are a significant component of the human diet and animal feed and have an important role in the environment, but the global diversity of agricultural legume species is currently underexploited. Experimental assessments of grain legume performances are required, to identify potential species with high yields. Here, we introduce a dataset including results of field experiments published in 173 articles. The selected experiments were carried out over five continents on 39 grain legume species. The dataset includes measurements of grain yield, aerial biomass, crop nitrogen content, residual soil nitrogen content and water use. When available, yields for cereals and oilseeds grown after grain legumes in the crop sequence are also included. The dataset is arranged into a relational database with nine structured tables and 198 standardized attributes. Tillage, fertilization, pest and irrigation management are systematically recorded for each of the 8,581 crop*field site*growing season*treatment combinations. The dataset is freely reusable and easy to update. We anticipate that it will provide valuable information for assessing grain legume production worldwide. PMID:27676125

Applying the ROBINS-I tool to natural experiments: an example from public health.

PubMed

Thomson, Hilary; Craig, Peter; Hilton-Boon, Michele; Campbell, Mhairi; Katikireddi, Srinivasa Vittal

2018-01-24

A new tool to assess Risk of Bias In Non-randomised Studies of Interventions (ROBINS-I) was published in Autumn 2016. ROBINS-I uses the Cochrane-approved risk of bias (RoB) approach and focusses on internal validity. As such, ROBINS-I represents an important development for those conducting systematic reviews which include non-randomised studies (NRS), including public health researchers. We aimed to establish the applicability of ROBINS-I using a group of NRS which have evaluated non-clinical public health natural experiments. Five researchers, all experienced in critical appraisal of non-randomised studies, used ROBINS-I to independently assess risk of bias in five studies which had assessed the health impacts of a domestic energy efficiency intervention. ROBINS-I assessments for each study were entered into a database and checked for consensus across the group. Group discussions were used to identify reasons underpinning lack of consensus for specific questions and bias domains. ROBINS-I helped to systematically articulate sources of bias in NRS. However, the lack of consensus in assessments for all seven bias domains raised questions about ROBINS-I's reliability and applicability for natural experiment studies. The two RoB domains with least consensus were selection (Domain 2) and performance (Domain 4). Underlying the lack of consensus were difficulties in applying an intention to treat or per protocol effect of interest to the studies. This was linked to difficulties in determining whether the intervention status was classified retrospectively at follow-up, i.e. post hoc. The overall risk of bias ranged from moderate to critical; this was most closely linked to the assessment of confounders. The ROBINS-I tool is a conceptually rigorous tool which focusses on risk of bias due to the counterfactual. Difficulties in applying ROBINS-I may be due to poor design and reporting of evaluations of natural experiments. While the quality of reporting may improve in the future, improved guidance on applying ROBINS-I is needed to enable existing evidence from natural experiments to be assessed appropriately and consistently. We hope future refinements to ROBINS-I will address some of the issues raised here to allow wider use of the tool.

PCMH characteristics were measured with surveys of randomly selected providers and staff; surveys generated 0 (worst) to 100 (best) scores for 5 subscales, and a total score. Patient experience was measured through surveying parents of pediatric patients. Questions from the Consumer Assessment of Healthcare Providers and Systems-Clinician and Group instrument produced 4 patient experience measures: timeliness, physician communication, staff helpfulness, and overall rating. To investigate the relationship between PCMH characteristics and patient experience, we used generalized estimating equations with an exchangeable correlation structure. We included 440 parents and 214 providers and staff in the analysis. Total PCMH score was not associated with parents' assessment of patient experience; however, PCMH subscales were associated with patient experience in different directions. In particular, quality improvement activities undertaken by clinics were strongly associated with positive ratings of patient experience, whereas patient care management activities were associated with more negative reports of patient experience. Future work should bolster features of the PCMH that work well for patients while investigating which PCMH features negatively impact patient experience, to yield a better patient experience overall.

to examine the effects of early skin-to-skin contact between mother and baby on the initiation and duration of breast feeding. electronic databases--the Cochrane Library, MEDLINE,CINAHL and EMBASE. References of studies were examined to identify additional trials and contact was made with researchers in the field. Study selection criteria: randomised or quasi-randomised controlled trials in any language in which skin-to-skin contact between mothers and their healthy full-term newborn babies was compared to routine contact. Primary outcomes were success of first breast feed and duration of breast feeding. Secondary outcomes included, baby temperature and behaviour. STUDY-QUALITY ASSESSMENT: validity of included studies was assessed using criteria defined by the Cochrane Collaboration. Application of inclusion criteria, validity assessment and data extraction were carried out independently by two reviewers with a third reviewer to resolve differences. seven randomised controlled trials were identified. Five studies assessed duration of breast feeding with mixed results. None of the studies assessed the success of the first breast-feeding experience. Study quality was variable with methods of randomisation and blinding of assessment unclear in four of the five studies providing relevant results. the findings of this systematic review fail to support the current initiatives to implement changes in clinical practice to include skin-to-skin contact. Methodological flaws within the included studies prohibit firm conclusions being reached with regard to the effect of skin-to-skin contact on the duration of breast feeding, timing of first breast feed or baby physiological factors. The review highlights the need for further primary research to assess the effect of skin-to-skin contact on the breast-feeding experience.

NASA Astronauts on Soyuz: Experience and Lessons for the Future

NASA Technical Reports Server (NTRS)

2010-01-01

The U. S., Russia, and, China have each addressed the question of human-rating spacecraft. NASA's operational experience with human-rating primarily resides with Mercury, Gemini, Apollo, Space Shuttle, and International Space Station. NASA s latest developmental experience includes Constellation, X38, X33, and the Orbital Space Plane. If domestic commercial crew vehicles are used to transport astronauts to and from space, Soyuz is another example of methods that could be used to human-rate a spacecraft and to work with commercial spacecraft providers. For Soyuz, NASA's normal assurance practices were adapted. Building on NASA's Soyuz experience, this report contends all past, present, and future vehicles rely on a range of methods and techniques for human-rating assurance, the components of which include: requirements, conceptual development, prototype evaluations, configuration management, formal development reviews (safety, design, operations), component/system ground-testing, integrated flight tests, independent assessments, and launch readiness reviews. When constraints (cost, schedule, international) limit the depth/breadth of one or more preferred assurance means, ways are found to bolster the remaining areas. This report provides information exemplifying the above safety assurance model for consideration with commercial or foreign-government-designed spacecraft. Topics addressed include: U.S./Soviet-Russian government/agency agreements and engineering/safety assessments performed with lessons learned in historic U.S./Russian joint space ventures

Measuring patient experience in dialysis: a new paradigm of quality assessment.

Rhee, Connie M; Brunelli, Steven M; Subramanian, Lalita; Tentori, Francesca

2018-04-01

Patients' experience of care (PEC) is as an important dimension in quality of care. As a distinct entity from patient satisfaction and patient health-related quality of life, PEC is defined as patients' perceptions of the range of interactions they have with the health care system, including care from providers, facilities, and health plans. While traditionally PEC may be ascertained via informal assessments, in recent years, especially in the United States, there has been a shift towards standardized surveillance of PEC amongst dialysis patients in order to: (1) set a normative expectation regarding the importance of PEC; (2) standardize the components of patients' experience that are assessed to minimize potential "blind spots"; (3) provide a direct "voice" to the patient in communicating perceptions of their care; (4) facilitate comparisons of quality across facilities; and (5) broaden accountability for PEC to the entire multidisciplinary dialysis care team. In this review, we will discuss the significance of PEC as a quality of care metric in dialysis patients; the history of PEC assessment across other health care arenas; the development of the In-Center Hemodialysis Consumer Assessment of Healthcare Provider and Systems survey as a means to standardize PEC assessment among US dialysis patients; experiences in PEC assessment across international dialysis populations; and future areas of research needed to refine the ascertainment of PEC and its impact upon patient outcomes.

Assessing signal-to-noise in quantitative proteomics: multivariate statistical analysis in DIGE experiments.

PubMed

Friedman, David B

2012-01-01

All quantitative proteomics experiments measure variation between samples. When performing large-scale experiments that involve multiple conditions or treatments, the experimental design should include the appropriate number of individual biological replicates from each condition to enable the distinction between a relevant biological signal from technical noise. Multivariate statistical analyses, such as principal component analysis (PCA), provide a global perspective on experimental variation, thereby enabling the assessment of whether the variation describes the expected biological signal or the unanticipated technical/biological noise inherent in the system. Examples will be shown from high-resolution multivariable DIGE experiments where PCA was instrumental in demonstrating biologically significant variation as well as sample outliers, fouled samples, and overriding technical variation that would not be readily observed using standard univariate tests.

Daily stress interacts with trait dissociation to predict sleep-related experiences in young adults.

2011-08-01

Building on the previously documented effects of stress and dissociation on sleep and dreaming, we examined their interactive role in general sleep-related experiences (GSEs; e.g., nightmares, falling dreams, hypnagogic hallucinations; see Watson, 2001). Stress, sleep quality, and GSEs were assessed daily for 14 days among young adults. Baseline assessment included life stress, sleep quality, psychopathology, dissociation, and related dimensions. Multilevel analyses indicated that daily stress brings about GSEs among highly dissociative young adults. Additionally, baseline trait dissociation predicted within-subject elevation in GSEs when daily stress was high. Flawed sleep-wake transitions, previously linked to dissociation and sleep-related experiences, might account for this effect. © 2011 American Psychological Association

Computer-based surgical simulators capture a multitude of metrics based on different aspects of performance, such as speed, accuracy, and movement efficiency. However, without rigorous assessment, it may be unclear whether all, some, or none of these metrics actually reflect technical skill, which can compromise educational efforts on these simulators. We assessed the construct validity of individual performance metrics on the LapVR simulator (Immersion Medical, San Jose, CA, USA) and used these data to create task-specific summary metrics. Medical students with no prior laparoscopic experience (novices, N = 12), junior surgical residents with some laparoscopic experience (intermediates, N = 12), and experienced surgeons (experts, N = 11) all completed three repetitions of four LapVR simulator tasks. The tasks included three basic skills (peg transfer, cutting, clipping) and one procedural skill (adhesiolysis). We selected 36 individual metrics on the four tasks that assessed six different aspects of performance, including speed, motion path length, respect for tissue, accuracy, task-specific errors, and successful task completion. Four of seven individual metrics assessed for peg transfer, six of ten metrics for cutting, four of nine metrics for clipping, and three of ten metrics for adhesiolysis discriminated between experience levels. Time and motion path length were significant on all four tasks. We used the validated individual metrics to create summary equations for each task, which successfully distinguished between the different experience levels. Educators should maintain some skepticism when reviewing the plethora of metrics captured by computer-based simulators, as some but not all are valid. We showed the construct validity of a limited number of individual metrics and developed summary metrics for the LapVR. The summary metrics provide a succinct way of assessing skill with a single metric for each task, but require further validation.

Reliability, validity and sensitivity of a computerized visual analog scale measuring state anxiety.

Assessment of state anxiety is frequently required in clinical and research settings, but its measurement using standard multi-item inventories entails practical challenges. Such inventories are increasingly complemented by paper-and-pencil, single-item visual analog scales measuring state anxiety (VAS-A), which allow rapid assessment of current anxiety states. Computerized versions of VAS-A offer additional advantages, including facilitated and accurate data collection and analysis, and applicability to computer-based protocols. Here, we establish the psychometric properties of a computerized VAS-A. Experiment 1 assessed the reliability, convergent validity, and discriminant validity of the computerized VAS-A in a non-selected sample. Experiment 2 assessed its sensitivity to increase in state anxiety following social stress induction, in participants with high levels of social anxiety. Experiment 1 demonstrated the computerized VAS-A's test-retest reliability (r = .44, p < .001); convergent validity with the State-Trait Anxiety Inventory's state subscale (STAI-State; r = .60, p < .001); and discriminant validity as indicated by significantly lower correlations between VAS-A and different psychological measures relative to the correlation between VAS-A and STAI-State. Experiment 2 demonstrated the VAS-A's sensitivity to changes in state anxiety via a significant pre- to during-stressor rise in VAS-A scores (F(1,48) = 25.13, p < .001). Set-order administration of measures, absence of clinically-anxious population, and gender-unbalanced samples. The adequate psychometric characteristics, combined with simple and rapid administration, make the computerized VAS-A a valuable self-rating tool for state anxiety. It may prove particularly useful for clinical and research settings where multi-item inventories are less applicable, including computer-based treatment and assessment protocols.

2013-05-01

The purpose of this descriptive study was to identify specific information related to U.S. dental hygiene baccalaureate degree completion programs. Learning experiences, assessment methods, and baccalaureate institutional partnerships were assessed. Of the sixty dental hygiene programs that offer a degree completion program, the forty-two that met the inclusion criteria (including having operated for at least three years) were invited to participate in a thirty-eight item online survey. A 62 percent (n=26) response rate was obtained. Learning experiences in responding programs included core dental hygiene courses, general education courses, and elective dental hygiene courses. Emphasis areas offered by various programs were in the specialty areas of education, public or community health, and research. Respondents reported that their graduates were employed in multiple settings (65 percent; n=17), with 19 percent (n=5) reporting employment in the combined grouping of private practice, education, and public health. Institutional partnerships included articulation agreements (88 percent; n=21), community college baccalaureate (8 percent; n=2), and university extension (4 percent; n=1) models. The findings of this study provide a baseline for assessing the educational composition and design of U.S. dental hygiene degree completion programs. However, results of this study showed inconsistencies among learning experiences that might raise concerns when considering students' level of preparation for graduate education and future leadership roles in the profession.

To determine the extent of correlation between stroke patients' experiences of hospital care with the quality of services assessed in a national audit. Patients' assessments of their care derived from survey data were linked to data obtained in the National Sentinel Stroke Audit 2004 for 670 patients in 51 English NHS trusts. A measure of patients' experience of hospital stroke care was derived by summing responses to 31 survey items and grouping these into three broad concept domains: quality of care; information; and relationships with staff. Audit data were extracted from hospital admissions data and management information to assess the organisation of services, and obtained retrospectively from patient records to evaluate the delivery of care. Patient survey responses were compared with audit measures of organisation of care and compliance with clinical process standards. Patient experience scores were positively correlated with clinicians' assessment of the organisational quality of stroke care, but were largely unrelated to clinical process standards. Responses to individual questions regarding communication about diagnosis revealed a discrepancy between clinicians' and patients' reports. Better organised stroke care is associated with more positive patient experiences. Examining areas of disparity between patients' and clinicians' reports is important for understanding the complex nature of healthcare and for identifying areas for quality improvement. Future evaluations of the quality of stroke services should include a validated patient experience survey in addition to audit of clinical records.

The Personal Experiences Checklist (PECK) was developed to provide a multidimensional assessment of a young person's personal experience of being bullied that covered the full range of bullying behaviors, including covert relational forms of bullying and cyber bullying. A sample of 647 school children were used to develop the scale, and a 2nd sample of 218 children completed the PECK and a battery of measures of bullying (including peer nomination), anxiety, depression, and self-esteem, to provide validity evidence. Test-retest reliability was assessed in a further sample of 78 students. Four factors emerged from a principal axis factoring consistent with the domains of relational-verbal bullying, cyber bullying, physical bullying, and bullying based on culture and were confirmed with confirmatory factor analysis. The data also supported a higher order bullying factor with direct effects on these 4 factors. All PECK scales showed good to excellent internal consistency (Cronbach's α range = .78-.91) and adequate test-retest reliability (range r = .61-.86). Most, but not all, expected relations were found with alternative methods of assessing bullying and measures of psychopathology. Taken together, the PECK provides a promising comprehensive and behaviorally focused dimensional measure of bullying.

Background Graduate medical education (GME) programs may struggle to provide the knowledge, skills, and experiences necessary to meet trainee career interests and goals beyond a clinical focus. Sponsoring institutions can partner with programs to deliver content not included in typical clinical experiences of GME programs. Objective To perform a needs assessment and to develop, implement, and measure acceptability and feasibility of an institution-wide GME Concentrations curriculum. Methods In response to the needs assessment, GME leadership developed 4 concentrations: (1) Resident-as-Teacher; (2) Patient Safety and Quality Improvement; (3) Law, Ethics, and Health Policy; and (4) Leaders in Medicine. We formed advisory committees that developed curricula for each concentration, including didactics, experiential learning, and individual project mentoring. Participants completed pre- and postassessments. We assessed feasibility and evaluated participant presentations and final projects. Results Over the course of 3 years, 91 trainees (of approximately 1000 trainees each year) from 36 GME programs (of 82 accredited programs) have participated in the program. The number of participants has increased each year, and 22 participants have completed the program overall. Cost for each participant is estimated at $500. Participant projects addressed a variety of education and health care areas, including curriculum development, quality improvement, and national needs assessments. Participants reported that their GME Concentrations experience enhanced their training and fostered career interests. Conclusions The GME Concentrations program provides a feasible, institutionally based approach for educating trainees in additional interest areas. Institutional resources are leveraged to provide and customize content important to participants' career interests beyond their specialty. PMID:26457150

We conducted detailed 2-dimensional hydrodynamics calculations to assess the quality of simulations commonly used to design and analyze simple shock compression experiments. Such simple shock experiments also contain data where dynamic properties of materials are integrated together. We wished to assess how well the chosen computer hydrodynamic code could do at capturing both the simple parts of the experiments and the integral parts. We began with very simple shock experiments, in which we examined the effects of the equation of state and the compressional and tensile strength models. We increased complexity to include spallation in copper and iron and amore » solid-solid phase transformation in iron to assess the quality of the damage and phase transformation simulations. For experiments with a window, the response of both the sample and the window are integrated together, providing a good test of the material models. While CTH physics models are not perfect and do not reproduce all experimental details well, we find the models are useful; the simulations are adequate for understanding much of the dynamic process and for planning experiments. However, higher complexity in the simulations, such as adding in spall, led to greater differences between simulation and experiment. Lastly, this comparison of simulation to experiment may help guide future development of hydrodynamics codes so that they better capture the underlying physics.« less

Cardiovascular disease (CVD) is a leading cause of mortality, and South Asian groups experience worse outcomes than the general population in the UK. Regular screening for CVD risk factors is recommended, but we do not know the best settings in which to deliver this for ethnically diverse populations. Health promotion in religious and community settings may reduce inequalities in access to cardiovascular preventative health care. To use stakeholders' and attendees' experiences to explore the feasibility and potential impact of cardiovascular risk assessment targeting South Asian groups at religious and community venues and how health checks in these settings might compare with general practice assessments. Qualitative semi-structured interviews were used. The settings were two Hindu temples, one mosque and one Bangladeshi community centre in central and north-west London. Twenty-four participants (12 stakeholders and 12 attendees) were purposively selected for interview. Interviews were recorded and transcribed verbatim. Themes from the data were generated using thematic framework analysis. All attendees reported positive experiences of the assessments. All reported making lifestyle changes after the check, particularly to diet and exercise. Barriers to lifestyle change, e.g. resistance to change from family members, were identified. Advantages of implementing assessments in religious and community settings compared with general practice included accessibility and community encouragement. Disadvantages included reduced privacy, organizational difficulties and lack of follow-up care. Cardiovascular risk assessment in religious and community settings has the potential to trigger lifestyle change in younger participants. These venues should be considered for future health promotional activities.

Multi-jurisdictional environmental impact assessment: Canadian experiences

Fitzpatrick, Patricia, E-mail: p.fitzpatrick@uwinnipeg.c; Sinclair, A. John, E-mail: Jsincla@ms.umanitoba.c

This research examines complexities surrounding environmental impact assessment (EIA) in a multi-jurisdictional environment, with a specific focus on opportunities for public participation. With almost universal adoption of EIA, projects are increasingly subject to more than one assessment process. Thus there is demand to facilitate inter-jurisdictional coordination of EIAs. Canada has growing expertise with multijuristictional EIA that serves to illustrate the costs and opportunities associated with three different approaches to coordination: standardization, harmonization and substitution. Findings suggest that, although fraught with issues, harmonization is the most realistic approach for coordinating efforts. Harmonization has the potential to minimize duplication, avoid process uncertaintymore » and increase efficiency and effectiveness in EIA. Furthermore, the analysis demonstrates that a bilateral agreement between jurisdictions is the best approach to harmonization, so long as negotiation of the agreement includes opportunities for meaningful participation, and implementation includes activities designed to communicate the assessment responsibilities of each jurisdiction, activities and schedules to the public. The experience of participants of different coordinated EIAs in Canada serves as counsel for on-going and future efforts to facilitate inter-jurisdictional coordination.« less

Objective. To assess the extent to which US colleges and schools of pharmacy are incorporating interprofessional education into their introductory pharmacy practice experiences (IPPEs), and to identify barriers to implementation; characterize the format, structure, and assessment; and identify factors associated with incorporating interprofessional education in IPPEs. Methods. An electronic survey of 116 US colleges and schools of pharmacy was conducted from March 2011 through May 2011. Results. Interprofessional education is a stated curricular goal in 78% of colleges and schools and consistently occurred in IPPEs in 55%. Most colleges and schools that included interprofessional education in IPPEs (70%) used subjective measures to assess competencies, while 17.5% used standardized outcomes assessment instruments. Barriers cited by respondents from colleges and schools that had not implemented interprofessional education in IPPEs included a lack of access to sufficient healthcare facilities with interprofessional education opportunities (57%) and a lack of required personnel resources (52%). Conclusions. Many US colleges and schools of pharmacy have incorporated interprofessional education into their IPPEs, but there is a need for further expansion of interprofessional education and better assessment related to achievement of interprofessional education competencies in IPPEs.

Single-Case Experimental Designs to Evaluate Novel Technology-Based Health Interventions

PubMed Central

Cassidy, Rachel N; Raiff, Bethany R

2013-01-01

Technology-based interventions to promote health are expanding rapidly. Assessing the preliminary efficacy of these interventions can be achieved by employing single-case experiments (sometimes referred to as n-of-1 studies). Although single-case experiments are often misunderstood, they offer excellent solutions to address the challenges associated with testing new technology-based interventions. This paper provides an introduction to single-case techniques and highlights advances in developing and evaluating single-case experiments, which help ensure that treatment outcomes are reliable, replicable, and generalizable. These advances include quality control standards, heuristics to guide visual analysis of time-series data, effect size calculations, and statistical analyses. They also include experimental designs to isolate the active elements in a treatment package and to assess the mechanisms of behavior change. The paper concludes with a discussion of issues related to the generality of findings derived from single-case research and how generality can be established through replication and through analysis of behavioral mechanisms.

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

Integration of classroom science performance assessment tasks by participants of the Wisconsin Performance Assessment Development Project (WPADP)

NASA Astrophysics Data System (ADS)

Tonnis, Dorothy Ann

The goals of this interpretive study were to examine selected Wisconsin science teachers' perceptions of teaching and learning science, to describe the scope of classroom performance assessment practices, and to gain an understanding of teachers' personal and professional experiences that influenced their belief systems of teaching, learning and assessment. The study was designed to answer the research questions: (1) How does the integration of performance assessment relate to the teachers' views of teaching and learning? (2) How are the selected teachers integrating performance assessment in their teaching? (3) What past personal and professional experiences have influenced teachers' attitudes and beliefs related to their classroom performance assessment practices? Purposeful sampling was used to select seven Wisconsin elementary, middle and high school science teachers who participated in the WPADP initiative from 1993-1995. Data collection methods included a Teaching Practices Inventory (TPI), semi-structured interviews, teacher developed portfolios, portfolio conferences, and classroom observations. Four themes and multiple categories emerged through data analysis to answer the research questions and to describe the results. Several conclusions were drawn from this research. First, science teachers who appeared to effectively integrate performance assessment, demonstrated transformational thinking in their attitudes and beliefs about teaching and learning science. In addition, these teachers viewed assessment and instructional practices as interdependent. Third, transformational teachers generally used well defined criteria to judge student work and made it public to the students. Transformational teachers provided students with real-world performance assessment tasks that were also learning events. Furthermore, student task responses informed the transformational teachers about effectiveness of instruction, students' complex thinking skills, quality of assessment instruments, students' creativity, and students' self-assessment skills. Finally, transformational teachers maintained integration of performance assessment practices through sustaining teacher support networks, engaging in professional development programs, and reflecting upon past personal and professional experiences related to teaching, learning and assessment. Salient conflicts overcome or minimized by transformational teachers include the conflict between assessment scoring and grading issues, validity and reliability concerns about the performance assessment tasks used, and the difficulty for teachers to consistently provide public criteria to students before task administration.

An assessment of antecedent events influencing noncompliance in an outpatient clinic.

2004-01-01

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

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

In tele-operation systems, damping is often injected to guarantee system stability during contact with hard objects. In this study, we used psychophysical experiments to assess the effect of adding damping on the user's perception of object hardness. In Experiments 1 and 2, combinations of stiffness and damping were tested to assess their effect on perceived hardness. In both experiments, two tasks were used: an in-contact task, starting at the object's surface, and a contact-transition task, including a free-air movement. In Experiment 3, the difference between inserting damping globally (equally throughout the workspace) and locally (inside the object only) was tested. In all experiments, the correlation between the participant's perceptual decision and force and position data was also investigated. Experiments 1 and 2 show that when injecting damping globally, perceived hardness slightly increased for an in-contact task, while it decreased considerably for a contact-transition task. Experiment 3 shows that this effect was mainly due to inserting damping globally, since there was a large perceptual difference between inserting damping globally and locally. The force and position parameters suggest that participants used the same force profile during the two movements of one trial and assessed the system's reaction to this force to perceive hardness.

Measurement of participant experience and satisfaction of exercise programs for low back pain: a structured literature review.

PubMed

Slade, Susan C; Keating, Jennifer L

2010-10-01

The objective of this review was to identify measuring instruments that might be suitable for assessment of satisfaction and experience of exercise programs designed to help people with persistent, recurrent low back pain. The review was designed as a structured literature review adapted from the Cochrane Collaboration Systematic Review and the Quality of Reporting of Meta-analyses and Preferred Reporting Items for Systematic Reviews and Meta-analyses Guidelines. A priori inclusion and exclusion criteria were established and electronic databases were searched without limits until February 2009. Data extraction guidelines were developed to extract the same information from each included article. Thematic analysis, conducted by two independent reviewers, was applied to identify emergent codes and themes from the questionnaires. The relevant questions were then evaluated for applicability to the back pain population. Ten potentially useful instruments were described in the 11 included articles. The following domains of experience were common to the included instruments: care-provider qualities, support staff, governance, access, and facilities. The answers to questions based on these themes may give valuable insights into the experience of exercise programs in general and for low back pain. Important information that would inform researchers and clinicians regarding the components of successful exercise programs may be gained from the development of an instrument that assesses experience of exercise program participation. Research into the experience of people who have participated in exercise programs may be a key to understanding their motivation, engagement, compliance or noncompliance and success or failure.

Cognitive impairment is a serious, often distressing aspect of schizophrenia that affects patients' day-to-day lives. Although several interview-based instruments exist to assess cognitive functioning, a reliable measure developed based on the experiences of patients facing cognitive difficulties is needed to complement the objective performance-based assessments. The present article describes the initial development of a patient-reported outcome (PRO) measure to assess the subjective experience of cognitive impairment among patients with schizophrenia, the Patient-Reported Experience of Cognitive Impairment in Schizophrenia (PRECIS). The phases of development included the construction of a conceptual model based on the existing knowledge and two sets of qualitative interviews with patients: 1) concept elicitation interviews to ensure face and content validity from the perspective of people with schizophrenia and 2) cognitive debriefing of the initial item pool. Input from experts was elicited throughout the process. The initial conceptual model included seven domains. The results from concept elicitation interviews (n=80) supported these domains but yielded substantive changes to concepts within domains and to terminology. Based on these results, an initial pool of 53 items was developed to reflect the most common descriptions and languages used by the study participants. Cognitive debriefing interviews (n=22) resulted in the removal of 18 items and modification of 22 other items. The remaining 35 items represented 23 concepts within six domains plus two items assessing bother. The draft PRO measure is currently undergoing psychometric testing as a precursor to broad-based clinical and research use.

Examining ethics - developing a comprehensive exam for a bioethics master's program.

Assessing mastery of bioethics in a graduate program requires careful attention not simply to the content knowledge and skill development of students but also to the principles of sound assessment processes. In this article, we describe the rationale, development process, and features of the comprehensive exam we created as a culminating experience of a master's program in bioethics. The exam became the students' opportunity to demonstrate the way they were able to integrate course, textual, and practical knowledge gained throughout the experience of the program. Additionally, the exam assessed students' proficiency in the field of bioethics and their ability to critically and constructively analyze bioethical issues. In this article, we offer tips to other exam creators regarding our experiences with question and answer development, scoring of the exam, and relationships between coursework and exam preparation and completion. We also include a sample rubric for others to see how we determined which student answers were satisfactory.

2012-10-01

Aetiological mechanisms underlying ethnic density associations with psychosis remain unclear. To assess potential mechanisms underlying the observation that minority ethnic groups experience an increased risk of psychosis when living in neighbourhoods of lower own-group density. Multilevel analysis of nationally representative community-level data (from the Ethnic Minorities Psychiatric Illness Rates in the Community survey), which included the main minority ethnic groups living in England, and a White British group. Structured instruments assessed discrimination, chronic strains and social support. The Psychosis Screening Questionnaire ascertained psychotic experiences. For every ten percentage point reduction in own-group density, the relative odds of reporting psychotic experiences increased 1.07 times (95% CI 1.01-1.14, P = 0.03 (trend)) for the total minority ethnic sample. In general, people living in areas of lower own-group density experienced greater social adversity that was in turn associated with reporting psychotic experiences. People resident in neighbourhoods of higher own-group density experience 'buffering' effects from the social risk factors for psychosis.

Boiling Experiment Facility for Heat Transfer Studies in Microgravity

NASA Technical Reports Server (NTRS)

Delombard, Richard; McQuillen, John; Chao, David

2008-01-01

Pool boiling in microgravity is an area of both scientific and practical interest. By conducting tests in microgravity, it is possible to assess the effect of buoyancy on the overall boiling process and assess the relative magnitude of effects with regards to other "forces" and phenomena such as Marangoni forces, liquid momentum forces, and microlayer evaporation. The Boiling eXperiment Facility is now being built for the Microgravity Science Glovebox that will use normal perfluorohexane as a test fluid to extend the range of test conditions to include longer test durations and less liquid subcooling. Two experiments, the Microheater Array Boiling Experiment and the Nucleate Pool Boiling eXperiment will use the Boiling eXperiment Facility. The objectives of these studies are to determine the differences in local boiling heat transfer mechanisms in microgravity and normal gravity from nucleate boiling, through critical heat flux and into the transition boiling regime and to examine the bubble nucleation, growth, departure and coalescence processes. Custom-designed heaters will be utilized to achieve these objectives.

Bazley, C; Vink, P; Montgomery, J; Hedge, A

2016-07-21

This study compared the effects of pre-experience and expectations on participant comfort upon waking, arrival to, and after an appointment, as well as the assessment of properly placed Feng Shui elements in three healthcare waiting rooms. Participants assessed comfort levels using self-report surveys. The researcher conducted 'intention interviews' with each doctor to assess the goals of each waiting area design, and conducted a Feng Shui assessment of each waiting area for properly placed Feng Shui elements. The waiting area designed by the Feng Shui expert rated 'most comfortable', followed by the waiting area design by a doctor, and the lowest comfort rating for the conventional waiting room design. Results show a sufficiently strong effect to warrant further research. Awareness of the external environment, paired with pre-experience and expectation, influences comfort for people over time. Fostering and encouraging a holistic approach to comfort utilizing eastern and western concepts and ergonomic principles creates a sense of "placeness" and balance in the design for comfort in built environments. This is new research information on the influences of the comfort experience over time, to include pre-experience, expectations and the placement of elements in the external environment.

Young women's experiences of psychotic illness: a systematic review of qualitative research.

2017-03-01

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

Culturally diverse health care students' experiences with teaching strategies in Finland: a national survey.

Pitkajarvi, Marianne; Eriksson, Elina; Pitkala, Kaisu

2013-06-01

All over the world, current health care students come from a variety of cultural, linguistic and educational backgrounds. Their expectations and learning needs vary, yet little is known about how our current education system meets their needs. The purpose of this study was to explore culturally diverse health care students' experiences of teaching strategies in polytechnic faculties of health care in Finland. Specifically, we aimed to compare how international students and Finnish students experience the same curriculum. A cross sectional survey. Ten polytechnic faculties of health care in Finland offering English-Language-Taught Degree Programmess (ELTDPs). 283 students studying nursing, public health nursing, or physiotherapy in English. Of these, 166 were international students and 112 were Finnish students. The data were collected using a questionnaire designed specifically for this study. The survey included items grouped into seven dimensions: 1. concreteness of theoretical instruction, 2. encouragement of student activity, 3. use of skills labs, 4. variation among teaching strategies, 5. assessment, 6. interaction in the English-Language-Taught Degree Programmes, and 7. approach to diversity in the English-Language-Taught Degree Programmes. The most positive experiences for all students were with the approach to cultural diversity and the concreteness of theoretical instruction, whereas the most negative experiences were with assessment. International students' experiences were more positive than Finnish students' in the following dimensions: encouragement of student activity (p=0.005), variation among teaching strategies (p<0.001), and assessment (p<0.001). Compared to the Finnish students, more than double the number of international students were dissatisfied with their lives (p<0.001). The implications for education include the strengthening teachers' leadership role in small group activities, providing individual and detailed feedback, and ensuring appropriate support mechanisms for all students.

2018-04-25

We assess the utility of the Public Involvement Impact Assessment Framework (PiiAF) as a resource to support research teams in assessing the impact of Public Involvement across diverse research and public involvement (PI) contexts. PiiAF was developed in response to a well-documented growth in Public Involvement in health research in the United Kingdom that demands a more sophisticated evidence base to demonstrate its impact. We used a reflective case study approach drawing on contemporaneous meeting notes, PiiAF website resources and retrospective reflections to describe how PiiAF helped us to develop an impact assessment plan of the PI in a university-based mental health research centre. We consider key aspects of our experiences of using PiiAF as a tool to help us design an impact assessment of PI, interpret these experiences with reference to relevant theory and research and share insights that may be useful to other teams considering using PiiAF. These insights include understanding the commitment of time and effort required to develop effective PI impact assessment plans; the flexibility of PiiAF and its ability to be used in a range of research and PI contexts; and the advantages of involving all stakeholders (including the public) in the development of an PI assessment plan. © 2018 The Authors.

2016-09-23

The aim of this project was to analyze and compare the educational experience in rheumatology specialty training programs across European countries, with a focus on self-reported ability. An electronic survey was designed to assess the training experience in terms of self-reported ability, existence of formal education, number of patients managed and assessments performed during rheumatology training in 21 core competences including managing specific diseases, generic competences and procedures. The target population consisted of rheumatology trainees and recently certified rheumatologists across Europe. The relationship between the country of training and the self-reported ability or training methods for each competence was analyzed through linear or logistic regression, as appropriate. In total 1079 questionnaires from 41 countries were gathered. Self-reported ability was high for most competences, range 7.5-9.4 (0-10 scale) for clinical competences, 5.8-9.0 for technical procedures and 7.8-8.9 for generic competences. Competences with lower self-reported ability included managing patients with vasculitis, identifying crystals and performing an ultrasound. Between 53 and 91 % of the trainees received formal education and between 7 and 61 % of the trainees reported limited practical experience (managing ≤10 patients) in each competence. Evaluation of each competence was reported by 29-60 % of the respondents. In adjusted multivariable analysis, the country of training was associated with significant differences in self-reported ability for all individual competences. Even though self-reported ability is generally high, there are significant differences amongst European countries, including differences in the learning structure and assessment of competences. This suggests that educational outcomes may also differ. Efforts to promote European harmonization in rheumatology training should be encouraged and supported.

Stratospheric controlled perturbation experiment: a small-scale experiment to improve understanding of the risks of solar geoengineering.

PubMed

Dykema, John A; Keith, David W; Anderson, James G; Weisenstein, Debra

2014-12-28

Although solar radiation management (SRM) through stratospheric aerosol methods has the potential to mitigate impacts of climate change, our current knowledge of stratospheric processes suggests that these methods may entail significant risks. In addition to the risks associated with current knowledge, the possibility of 'unknown unknowns' exists that could significantly alter the risk assessment relative to our current understanding. While laboratory experimentation can improve the current state of knowledge and atmospheric models can assess large-scale climate response, they cannot capture possible unknown chemistry or represent the full range of interactive atmospheric chemical physics. Small-scale, in situ experimentation under well-regulated circumstances can begin to remove some of these uncertainties. This experiment-provisionally titled the stratospheric controlled perturbation experiment-is under development and will only proceed with transparent and predominantly governmental funding and independent risk assessment. We describe the scientific and technical foundation for performing, under external oversight, small-scale experiments to quantify the risks posed by SRM to activation of halogen species and subsequent erosion of stratospheric ozone. The paper's scope includes selection of the measurement platform, relevant aspects of stratospheric meteorology, operational considerations and instrument design and engineering.

This report summarizes the state of salt repository science, reviews many of the technical issues pertaining to disposal of heat-generating nuclear waste in salt, and proposes several avenues for future science-based activities to further the technical basis for disposal in salt. There are extensive salt formations in the forty-eight contiguous states, and many of them may be worthy of consideration for nuclear waste disposal. The United States has extensive experience in salt repository sciences, including an operating facility for disposal of transuranic wastes. The scientific background for salt disposal including laboratory and field tests at ambient and elevated temperature, principlesmore » of salt behavior, potential for fracture damage and its mitigation, seal systems, chemical conditions, advanced modeling capabilities and near-future developments, performance assessment processes, and international collaboration are all discussed. The discussion of salt disposal issues is brought current, including a summary of recent international workshops dedicated to high-level waste disposal in salt. Lessons learned from Sandia National Laboratories' experience on the Waste Isolation Pilot Plant and the Yucca Mountain Project as well as related salt experience with the Strategic Petroleum Reserve are applied in this assessment. Disposal of heat-generating nuclear waste in a suitable salt formation is attractive because the material is essentially impermeable, self-sealing, and thermally conductive. Conditions are chemically beneficial, and a significant experience base exists in understanding this environment. Within the period of institutional control, overburden pressure will seal fractures and provide a repository setting that limits radionuclide movement. A salt repository could potentially achieve total containment, with no releases to the environment in undisturbed scenarios for as long as the region is geologically stable. Much of the experience gained from United States repository development, such as seal system design, coupled process simulation, and application of performance assessment methodology, helps define a clear strategy for a heat-generating nuclear waste repository in salt.« less

Understanding the role of culture in pain: Māori practitioner perspectives of pain descriptors.

PubMed

Magnusson, Jane E; Fennell, Joyce A

2011-01-21

There is growing interest in the role of cultural diversity within healthcare settings yet minority ethnic groups are underrepresented in the healthcare literature, including the literature on pain. To better assess and treat pain in different cultures the perspectives and experiences of that culture must be taken into consideration and therefore the present study was undertaken to better understand Māori perspectives of pain. Māori healthcare providers and kaumātua (tribal leaders/elders) completed questionnaires relating to the experience of pain and were asked to provide feedback regarding the suitability of words and phrases typically used to describe symptoms of pain and pain-related disability. Participants were also asked to provide words, or phrases (in te reo Māori or English) representing characteristics of pain which had not been provided but would be useful in the assessment of pain in a Māori population. All of the pain descriptors, and 92% of the phrases regarding the experience of pain, provided were endorsed by the majority of participants demonstrating that, as in many cultures, Māori perceive pain as a multidimensional experience impacting them on physiological, psychological, and social dimensions and that the terms and phrases of measures commonly used to assess pain appropriately capture their pain experiences. The implications of these findings are that established measures can be used when assessing pain in Māori. However, it is beneficial to confirm that the descriptors used in those measures accurately capture the experiences being measured.

Study to perform preliminary experiments to evaluate particle generation and characterization techniques for zero-gravity cloud physics experiments

NASA Technical Reports Server (NTRS)

Katz, U.

1982-01-01

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

Book Club Elective to Facilitate Student Learning of the Patient Experience With Chronic Disease

PubMed Central

2010-01-01

Objectives To evaluate the impact of a book club experience on pharmacy students' learning about chronic illness. Design Students read autobiographies/biographies regarding the patient experience of chronic illness. Similar to a traditional book club, small group discussions were held based on questions submitted by students. Other activities included written reflections, a final paper, and an oral presentation. Assessment A retrospective pretest and posttest were administered at the end of the course. Students indicated improvement in the key aspects of the course with significant differences (p < 0.01) between retrospective pretest and posttest scores for all course objectives assessed. Students also indicated that the course contributed to their development as pharmacists, motivated them to learn about new topics, and helped them reconsider their attitudes. Conclusion A book club elective course was successful in helping students understand the patient experience. PMID:20498730

PubMed

Sato, Takahiro; Haegele, Justin A; Foot, Rachel

2017-04-01

The purpose of this study was to investigate in-service physical education (PE) teachers' experiences during online adapted physical education (APE) graduate courses. Based on andragogy theory (adult learning theory) we employed a descriptive qualitative methodology using an explanatory case study design. The participants (6 female and 3 male) were in-service PE teachers enrolled in an online graduate APE endorsement program. Data collection included journal reflection reports and face-to-face interviews. A constant comparative method was used to interpret the data. Three interrelated themes emerged from the participants' narratives. The first theme, instructor communication, exposes the advantages and disadvantages the participants perceived regarding communication while enrolled in the online APE graduate courses. The second theme, bulletin board discussion experiences, described participants' perceptions of the use of the bulletin board discussion forum. Lastly, the final theme, assessment experiences, described how the participants learned knowledge and skills through online courses related to assessment and evaluation.

2006-01-01

Objectives To determine the usefulness of a teaching and learning tool used to create structure for advanced pharmacy practice experiences (APPEs) in community pharmacy settings, and to identify differences between respondents' perspectives on the relevance and practicality of implementing specific community pharmacy-related topics during the experience. Design Community practice faculty members designed a manual that outlined a week-by-week schedule of student activities, consistent with the Center for the Advancement of Pharmaceutical Education (CAPE) outcome-based goals, and included associated teaching, documentation, and assessment tools. The manual was distributed to site preceptors and students. Assessment Eighty-six PharmD students responded to a questionnaire upon completion of their community APPE. Student feedback concerning the impact of the manual relative to interactions with site preceptors and their overall learning experience was relatively positive. Conclusion The manual was an effective teaching and learning tool for students completing a community APPE. PMID:17149421

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

PubMed

Wahlheim, Christopher N; DeSoto, K Andrew

2017-02-01

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

Chlorine is a significant source of corrosion and deposition, both from coal and from biomass, and in PF boilers. This investigation was designed to highlight the potential for corrosion risks associated with once-through units and advanced cycles. The research took the form of a detailed literature investigation to evaluate chlorine in solid fuels: coals of various ranks and origins, biomass fuels of a variety of types, petroleum cokes, and blends of the above. The investigation focused upon an extensive literature review of documents dating back to 1991. The focus is strictly corrosion and deposition. To address the deposition and corrosionmore » issues, this review evaluates the following considerations: concentrations of chlorine in available solid fuels including various coals and biomass fuels, forms of chlorine in those fuels, and reactions - including reactivities - of chlorine in such fuels. The assessment includes consideration of alkali metals and alkali earth elements as they react with, and to, the chlorine and other elements (e.g., sulfur) in the fuel and in the gaseous products of combustion. The assessment also includes other factors of combustion: for example, combustion conditions including excess O{sub 2} and combustion temperatures. It also considers analyses conducted at all levels: theoretical calculations, bench scale laboratory data and experiments, pilot plant experiments, and full scale plant experience. Case studies and plant surveys form a significant consideration in this review. The result of this investigation focuses upon the concentrations of chlorine acceptable in coals burned exclusively, in coals burned with biomass, and in biomass cofired with coal. Values are posited based upon type of fuel and combustion technology. Values are also posited based upon both first principles and field experience. 86 refs., 8 figs., 7 tabs.« less

Do surgeon interviewers have human factor-related issues during the long day UK National Trauma and Orthopaedic specialty recruitment process?

2018-03-05

The role that human factors (HF) play in contributing to medical error is increasingly being recognised by healthcare professionals. Surprisingly, much less is known about the possible effects of HF including boredom, fatigue and organisational influences, on performance outside of the clinical environment such as examining or assessing candidates in other high stakes situations. The authors used a validated 38 response questionnaire based around the HF analysis and classification system (HFACS) to assess factors including stress and pressure, care and support and working within the rules for surgeon interviewers at the UK national trainee selection process in Trauma and Orthopaedic surgery. 121 completed questionnaires were analysed (86% response rate). No statistically significant differences were found between interviewer experience, grade or role at the interview and the mean scores obtained for all four factor items. Overall interviewers had a positive experience during national selection with mean factor scores ranging from 3.80 to 3.98 (out of a maximum satisfaction score of 5). Careful planning by organisations and recognising the importance of the human element are essential to ensure assessors are looked after properly during high stakes assessment processes. Our data suggests that a positive experience for examiners is likely to benefit candidate performance and contribute to a fair and reliable recruitment process. The relationship between examiner experience and candidate performance merits further investigation. Crown Copyright © 2018. Published by Elsevier Ltd. All rights reserved.

Dental pulp stem cells for in vivo bone regeneration: a systematic review of literature.

Morad, Golnaz; Kheiri, Lida; Khojasteh, Arash

2013-12-01

This review of literature was aimed to assess in vivo experiments which have evaluated the efficacy of dental pulp stem cells (DPSCs) for bone regeneration. An electronic search of English-language papers was conducted on PubMed database. Studies that assessed the use of DPSCs in bone regeneration in vivo were included and experiments evaluating regeneration of hard tissues other than bone were excluded. The retrieved articles were thoroughly reviewed according to the source of stem cell, cell carrier, the in vivo experimental model, defect type, method of evaluating bone regeneration, and the obtained results. Further assessment of the results was conducted by classifying the studies based on the defect type. Seventeen papers formed the basis of this systematic review. Sixteen out of 17 experiments were performed on animal models with mouse and rat being the most frequently used animal models. Seven out of 17 animal studies, contained subcutaneous pockets on back of the animal for stem cell implantation. In only one study hard tissue formation was not observed. Other types of defects used in the retrieved studies, included cranial defects and mandibular bone defects, in all of which bone formation was reported. When applied in actual bone defects, DPSCs were capable of regenerating bone. Nevertheless, a precise conclusion regarding the efficiency of DPSCs for bone regeneration is yet to be made, considering the limited number of the in vivo experiments and the heterogeneity within their methods.

2010-03-01

To assess wheelchair users' perceptions of and experiences with power assist wheels using qualitative interview methods. Qualitative evaluations were conducted in a laboratory setting with a focus on users' experiences using power assist wheel in their naturalistic environments. Participants consisted of seven women and 13 men (M(age) = 42.75, SD = 14.68) that included one African American, one Hispanic, 17 whites, and one individual from Zambia. Qualitative interviews were conducted before, during, and after use of a power assist wheel. Main outcome measures included the wheelchair users' evaluations and experiences related to the use of power assist wheels. The primary evaluations included wheeling on challenging terrains, performance of novel activities, social/family aspects, fatigue, and pain. These descriptions indicated that most participants perceived positive experiences with the power assist wheels, including access to new and different activities. Secondary evaluations indicated that the unit was cumbersome and prohibitive for some participants because of difficulties with transport in and out of a vehicle and battery life. Most participants felt that power assist wheels provided more independence and social opportunities. The power assist wheel seems to offer physical and social benefits for most wheelers. Clinicians should consider users' home environment and overall life circumstances before prescribing.

2016-09-01

Objective The aim of the present study was to develop and pilot a measure of patient satisfaction that encompasses themes, activities, settings and interactions specific to the neuropsychological assessment process. Methods A focus group of out-patients (n=15) was surveyed to identify the factors commonly associated with a satisfactory neuropsychological experience. Responses informed a purposely designed 14-item patient satisfaction scale (α=0.88) that was completed by 66 hospital out-patients with mild to moderate cognitive impairment. Results Satisfaction with the neuropsychological assessment process was generally reported, with the testing phase (85%) rated significantly more favourably than the pre-assessment (79%) and feedback (70%) phases. Commentaries provided by 32 respondents identified interpersonal facilitators to a satisfactory neuropsychological assessment experience, but also dissatisfaction with physical aspects of the testing environment in addition to service availability. Conclusions The patient satisfaction scale can be used as a quality assurance tool to evaluate neuropsychological service delivery. Large-scale research is needed to confirm the scale's psychometric properties. Further research may also include a broader perspective on the consumers' experience of neuropsychological services.

Considerations that will determine if competency-based assessment is a sustainable innovation.

PubMed

Dauphinee, W Dale; Boulet, John R; Norcini, John J

2018-05-18

Educational assessment for the health professions has seen a major attempt to introduce competency based frameworks. As high level policy developments, the changes were intended to improve outcomes by supporting learning and skills development. However, we argue that previous experiences with major innovations in assessment offer an important road map for developing and refining assessment innovations, including careful piloting and analyses of their measurement qualities and impacts. Based on the literature, numerous assessment workshops, personal interactions with potential users, and our 40 years of experience in implementing assessment change, we lament the lack of a coordinated approach to clarify and improve measurement qualities and functionality of competency based assessment (CBA). To address this worrisome situation, we offer two roadmaps to guide CBA's further development. Initially, reframe and address CBA as a measurement development opportunity. Secondly, using a roadmap adapted from the management literature on sustainable innovation, the medical assessment community needs to initiate an integrated plan to implement CBA as a sustainable innovation within existing educational programs and self-regulatory enterprises. Further examples of down-stream opportunities to refocus CBA at the implementation level within faculties and within the regulatory framework of the profession are offered. In closing, we challenge the broader assessment community in medicine to step forward and own the challenge and opportunities to reframe CBA as an innovation to improve the quality of the clinical educational experience. The goal is to optimize assessment in health education and ultimately improve the public's health.

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

Nalubega, Sylivia; Evans, Catrin

2015-06-12

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

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

2015-09-01

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

The present study was aimed at testing the ability of a rheumatologist without experience in ultrasound (US) who attended an intensive 4-week training programme focused on US assessing bone erosions in the hands and feet in patients with RA. Twenty patients diagnosed with RA according to the ACR criteria were included in the study. All US examinations were performed bilaterally by two investigators (with different experience in the field of musculoskeletal US) at the following sites: the dorsal, lateral and volar aspect of the second metacarpal, ulnar and fifth metatarsal head; and the dorsal and volar aspect of the third metacarpal and second proximal heads. Each quadrant was scanning in longitudinal and transverse scans for assessing the qualitative, semiquantitative and quantitative US findings indicative of bone erosions according the OMERACT preliminary definition. Both κ-values and overall agreement percentages of qualitative and semiquantitative assessments showed moderate to excellent agreement between the two investigators. Similar results were obtained for the quantitative assessment with the concordance correlation coefficient value always significant. The only exception was the volar aspects, in particular those of the fifth metatarsal head. Our study suggests that after a 4-week dedicated training programme, a rheumatologist without experience in US is able to detect and score bone erosions in the hands and feet of patients with RA.

This study assessed the efficacy of Second Life (SL) in delivering lectures and demonstrating clinical procedures. Sixteen students in a dental school in Alexandria, Egypt, volunteered to participate in SL to learn about topical fluoride through lectures and YouTube videos demonstrating the application of fluoride gel. This was followed by face to face (F2F) sessions about pits and fissures sealant including lectures and F2F demonstration. Knowledge improvement was assessed by pre- and posttests; practical skills were assessed by a checklist; and percent scores were calculated. The relation between these scores and some background variables was assessed. Students' satisfaction with and perceptions of SL were also assessed. Knowledge improved significantly after both SL and F2F experiences (p<0.0001 for both). There were no significant differences between SL and F2F in knowledge improvement or skills percent scores (p=0.16 and 0.26, respectively). Knowledge improvement was significantly related to previous experience with SL and previous year grade (p=0.02 and 0.007, respectively) but not to gender. Practical skills scores were not related to any of these three variables. Satisfaction with SL experience was high and not affected by any of the three variables, and the experience was perceived positively. This study suggests that SL can complement traditional F2F teaching, especially for underachieving students and in higher education institutions with problems of increasing numbers of students and limited space.

BACKGROUND American Indian/Alaska Native (AI/AN) women have lower breast cancer (BCA) screening and 5-year survival rates than non-Hispanic Whites. Understanding reasons for low screening rates is important to combat later stage diagnoses. The purpose of this study was to assess mammography experiences and satisfaction among AI/AN women. METHODS Nine focus groups were held with rural (N=15) and urban (N=38) AI/AN women 40 years and older in Kansas and Kansas City, Missouri, living both near and far from Indian Health Service (IHS) and tribal facilities, to examine experiences and satisfaction with mammography. Transcripts were coded and themes identified using a community-based participatory research approach. FINDINGS Themes were classified under knowledge, communication, and awareness of breast cancer, barriers to mammography, mammogram facility size, impressions of mammogram technologist, motivations to getting a mammogram, and how to improve the mammogram experience. Participants had knowledge of prevention, but described cultural reasons for not discussing it and described better experiences in smaller facilities. Participants indicated having a mammogram technologist who was friendly, knowledgeable, respectful, competent, and explained the test was a determining factor in satisfaction. Other factors included family history, physician recommendation, and financial incentives. Barriers included transportation, cost, perceptions of prejudice, and time constraints. Participants on reservations or near IHS facilities preferred IHS over mainstream providers. Suggestions for improvement included caring technologists, better machines with less discomfort, and education. CONCLUSIONS Interventions to enhance the professionalism, empathy, and cultural awareness of mammogram technologists, reduce barriers, and provide positive expectations and incentives could improve satisfaction and compliance with screening mammography.

Svarre, Tanja; Lunn, Tine Bieber Kirkegaard; Helle, Tina

2017-11-01

The aim of this paper is to provide the reader with an overall impression of the stepwise user-centred design approach including the specific methods used and lessons learned when transforming paper-based assessment forms into a prototype app, taking the Housing Enabler as an example. Four design iterations were performed, building on a domain study, workshops, expert evaluation and controlled and realistic usability tests. The user-centred design process involved purposefully selected participants with different Housing Enabler knowledge and housing adaptation experience. The design iterations resulted in the development of a Housing Enabler prototype app. The prototype app has several features and options that are new compared with the original paper-based Housing Enabler assessment form. These new features include a user friendly overview of the assessment form; easy navigation by swiping back and forth between items; onsite data analysis; and ranking of the accessibility score, photo documentation and a data export facility. Based on the presented stepwise approach, a high-fidelity Housing Enabler prototype app was successfully developed. The development process has emphasized the importance of combining design participants' knowledge and experiences, and has shown that methods should seem relevant to participants to increase their engagement.

To assess Canadian obstetrics and gynaecology residents' knowledge of and experience in Indigenous women's health (IWH), including a self-assessment of competency, and to assess the ability of residency program directors to provide a curriculum in IWH and to assess the resources available to support this initiative. Surveys for residents and for program directors were distributed to all accredited obstetrics and gynaecology residency programs in Canada. The resident survey consisted of 20 multiple choice questions in four key areas: general knowledge regarding Indigenous peoples in Canada; the impact of the residential school system; clinical experience in IWH; and a self-assessment of competency in IWH. The program director survey included an assessment of the content of the curriculum in IWH and of the resources available to support this curriculum. Residents have little background knowledge of IWH and the determinants of health, and are aware of their knowledge gap. Residents are interested in IWH and recognize the importance of IWH training for their future practice. Program directors support the development of an IWH curriculum, but they lack the resources to provide a comprehensive IWH curriculum and would benefit from having a standardized curriculum available. A nationwide curriculum initiative may be an effective way to facilitate the provision of education in IWH while decreasing the need for resources in individual programs.

Patient experience and hospital profitability: Is there a link?

PubMed

Richter, Jason P; Muhlestein, David B

Patient experience has had a direct financial impact on hospitals since value-based purchasing was instituted by the Centers for Medicare & Medicaid Services in 2013 as a method to reward or punish hospitals based on performance on various measures, including patient experience. Although other industries have shown an indirect impact of customer experience on overall profitability, that link has not been well established in the health care industry. Return-to-provider rate and perceptions of health quality have been associated with profitability in the health care industry. Our aims were to assess whether, independent of a direct financial impact, a more positive patient experience is associated with increased profitability and whether a more negative patient experience is associated with decreased profitability. We used a sample of 19,792 observations from 3767 hospitals over the 6-year period 2007-2012. The data were sourced from Centers for Medicare & Medicaid Services and Hospital Consumer Assessment of Healthcare Providers and Systems. Using generalized estimating equations to account for repeated measures, we fit four separate models for three dependent variables: net patient revenue, net income, and operating margin. Each model included one of the following independent variables of interest: percentage of patients who definitely recommend the hospital, percentage of patients who definitely would not recommend the hospital, percentage of patients who rated the hospital 9 or 10, and percentage of patients who rated the hospital 6 or lower. We identified that a positive patient experience is associated with increased profitability and a negative patient experience is even more strongly associated with decreased profitability. Management should have greater justification for incurring costs associated with bolstering patient experience programs. Improvements in training, technology, and staffing can be justified as a way to improve not only quality but now profitability as well.

Diabetes incidence is rising among vulnerable population subgroups including minorities and individuals with limited education. Many diabetes-related programs and public policies are unevaluated while others are analyzed with research designs highly susceptible to bias which can result in flawed conclusions. The Natural Experiments for Translation in Diabetes 2.0 (NEXT-D2) Network includes eight research centers and three funding agencies using rigorous methods to evaluate natural experiments in health policy and program delivery. NEXT-D2 research studies use quasi-experimental methods to assess three major areas as they relate to diabetes: health insurance expansion; healthcare financing and payment models; and innovations in care coordination. The studies will report on preventive processes, achievement of diabetes care goals, and incidence of complications. Some studies assess healthcare utilization while others focus on patient-reported outcomes. NEXT-D2 examines the effect of public and private policies on diabetes care and prevention at a critical time, given ongoing and rapid shifts in the US health policy landscape.

While a growing body of evidence suggest that social capital including interpersonal trust and reciprocity might be associated with mental health outcomes, few studies have explored the relationship with suicidal behaviors. This research examined the prospective association between interpersonal trust and reciprocity and suicidal behaviors using the Korea Welfare Panel Study, a nationally representative longitudinal cohort dataset in South Korea. Interpersonal trust and reciprocity were assessed at the 7th wave of the survey (2012), and each measure was classified into two categories (low vs. high). Experience of suicidal ideation, planning, and attempt was assessed between the 8th (2013) and 10th wave (2015) of the surveys. After adjusting for confounders including lifetime experience of suicidal behaviors at the 7th wave of the survey (2012) as well as socio-demographic information, the low interpersonal trust group was more likely to experience suicidal ideation (OR: 1.30, 95% CI: 1.11-1.53) compared to the high interpersonal trust group whereas no statistically significant association was observed in the reciprocity analysis.

Objectives. We examined the relationship between parents’ experiences of racism and children’s well-being and the influence of the residential neighborhood characteristics on this relationship. Methods. African American families were recruited from Baltimore neighborhoods. Parental measures included racism experiences and coping. Neighborhood measures included demographic characteristics, social cohesion, and social climate. Children’s mental health was assessed with the Child Behavior Checklist. Analysis was performed with multilevel modeling. Results. Parents who denied experiences of racism also reported higher rates of behavior problems among their preschool-aged children. For families living in neighborhoods characterized by fear of victimization, parents who actively coped with racism experiences by confronting the person involved or taking some sort of action in response to racism reported lower rates of anxiety and depression for their preschool-aged children. Conclusions. Experiences of and responses to racism among African American parents have important effects on the well-being of their young children. PMID:15569963

2014-02-01

Low-cost, objective systems to assess and train endoscopy skills are needed. The aim of this study was to evaluate the ability of Simulated Colonoscopy Objective Performance Evaluation to assess the skills required to perform endoscopy. Thirty-eight subjects were included in this study, all of whom performed 4 tasks. The scoring system measured performance by calculating precision and efficiency. Data analysis assessed the relationship between colonoscopy experience and performance on each task and the overall score. Endoscopic trainees' Simulated Colonoscopy Objective Performance Evaluation scores correlated significantly with total colonoscopy experience (r = .61, P = .003) and experience in the past 12 months (r = .63, P = .002). Significant differences were seen among practicing endoscopists, nonendoscopic surgeons, and trainees (P < .0001). When the 4 tasks were analyzed, each showed significant correlation with colonoscopy experience (scope manipulation, r = .44, P = .044; tool targeting, r = .45, P = .04; loop management, r = .47, P = .032; mucosal inspection, r = .65, P = .001) and significant differences in performance between the endoscopist groups, except for mucosal inspection (scope manipulation, P < .0001; tool targeting, P = .002; loop management, P = .0008; mucosal inspection, P = .27). Simulated Colonoscopy Objective Performance Evaluation objectively assesses the technical skills required to perform endoscopy and shows promise as a platform for proficiency-based skills training.

Reid, Brian J; Papanikolaou, Niki D; Wilcox, Ronah K

2005-02-01

The catabolic activity with respect to the systemic herbicide isoproturon was determined in soil samples by (14)C-radiorespirometry. The first experiment assessed levels of intrinsic catabolic activity in soil samples that represented three dissimilar soil series under arable cultivation. Results showed average extents of isoproturon mineralisation (after 240 h assay time) in the three soil series to be low. A second experiment assessed the impact of addition of isoproturon (0.05 microg kg(-1)) into these soils on the levels of catabolic activity following 28 days of incubation. Increased catabolic activity was observed in all three soils. A third experiment assessed levels of intrinsic catabolic activity in soil samples representing a single soil series managed under either conventional agricultural practice (including the use of isoproturon) or organic farming practice (with no use of isoproturon). Results showed higher (and more consistent) levels of isoproturon mineralisation in the soil samples collected from conventional land use. The final experiment assessed the impact of isoproturon addition on the levels of inducible catabolic activity in these soils. The results showed no significant difference in the case of the conventional farm soil samples while the induction of catabolic activity in the organic farm soil samples was significant.

2010-01-01

Based on a recent patient survey from Taiwan, where there is universal health insurance coverage and unrestricted physician choice, this study examined the relationship between physician specialty and the quality of primary medical care experiences. We assessed ambulatory patients' experiences with medical care using the Primary Care Assessment Tool, representing 7 primary care domains: first contact (ie, accessibility and utilization); longitudinality (ie, ongoing care); coordination (ie, referrals and information systems); comprehensiveness (ie, services available and provided); family centeredness; community orientation; and cultural competence. Having a primary care physician was significantly associated with patients reporting higher quality of primary care experiences. Specifically, relative to specialty care physicians, primary care physicians enhanced accessibility, achieved better community orientation and cultural competence, and provided more comprehensive services. In an area with universal health insurance and unrestricted physician choice, ambulatory patients of primary care physicians rated their medical care experiences as superior to those of patients of specialists. In addition to providing health insurance coverage, promoting primary care should be included as a health policy to improve patients' quality of ambulatory medical care experiences.

Background Aetiological mechanisms underlying ethnic density associations with psychosis remain unclear. Aims To assess potential mechanisms underlying the observation that minority ethnic groups experience an increased risk of psychosis when living in neighbourhoods of lower own-group density. Method Multilevel analysis of nationally representative community-level data (from the Ethnic Minorities Psychiatric Illness Rates in the Community survey), which included the main minority ethnic groups living in England, and a White British group. Structured instruments assessed discrimination, chronic strains and social support. The Psychosis Screening Questionnaire ascertained psychotic experiences. Results For every ten percentage point reduction in own-group density, the relative odds of reporting psychotic experiences increased 1.07 times (95% CI 1.01–1.14, P = 0.03 (trend)) for the total minority ethnic sample. In general, people living in areas of lower own-group density experienced greater social adversity that was in turn associated with reporting psychotic experiences. Conclusions People resident in neighbourhoods of higher own-group density experience ‘buffering’ effects from the social risk factors for psychosis. PMID:22844021

Scientific assessment of animal welfare.

Hemsworth, P H; Mellor, D J; Cronin, G M; Tilbrook, A J

Animal welfare is a state within the animal and a scientific perspective provides methodologies for evidence-based assessment of an animal's welfare. A simplistic definition of animal welfare might be how the animal feels now. Affective experiences including emotions, are subjective states so cannot be measured directly in animals, but there are informative indirect physiological and behavioural indices that can be cautiously used to interpret such experiences. This review enunciates several key science-based frameworks for understanding animal welfare. The biological functioning and affective state frameworks were initially seen as competing, but a recent more unified approach is that biological functioning is taken to include affective experiences and affective experiences are recognised as products of biological functioning, and knowledge of the dynamic interactions between the two is considered to be fundamental to managing and improving animal welfare. The value of these two frameworks in understanding the welfare of group-housed sows is reviewed. The majority of studies of the welfare of group-housed sows have employed the biological functioning framework to infer compromised sow welfare, on the basis that suboptimal biological functioning accompanies negative affective states such as sow hunger, pain, fear, helplessness, frustration and anger. Group housing facilitates social living, but group housing of gestating sows raises different welfare considerations to stall housing, such as high levels of aggression, injuries and stress, at least for several days after mixing, as well as subordinate sows being underfed due to competition at feeding. This paper highlights the challenges and potential opportunities for the continued improvement in sow management through well-focused research and multidisciplinary assessment of animal welfare. In future the management of sentient animals will require the promotion of positive affective experiences in animals and this is likely to be a major focus for animal welfare science activity in the early twenty-first century.

Automated verbal credibility assessment of intentions: The model statement technique and predictive modeling

PubMed Central

van der Toolen, Yaloe; Vrij, Aldert; Arntz, Arnoud; Verschuere, Bruno

2018-01-01

Summary Recently, verbal credibility assessment has been extended to the detection of deceptive intentions, the use of a model statement, and predictive modeling. The current investigation combines these 3 elements to detect deceptive intentions on a large scale. Participants read a model statement and wrote a truthful or deceptive statement about their planned weekend activities (Experiment 1). With the use of linguistic features for machine learning, more than 80% of the participants were classified correctly. Exploratory analyses suggested that liars included more person and location references than truth‐tellers. Experiment 2 examined whether these findings replicated on independent‐sample data. The classification accuracies remained well above chance level but dropped to 63%. Experiment 2 corroborated the finding that liars' statements are richer in location and person references than truth‐tellers' statements. Together, these findings suggest that liars may over‐prepare their statements. Predictive modeling shows promise as an automated veracity assessment approach but needs validation on independent data.

Six rapid assessments of alcohol and other substance use in populations displaced by conflict

PubMed Central

2011-01-01

Background Substance use among populations displaced by conflict is a neglected area of public health. Alcohol, khat, benzodiazepine, opiate, and other substance use have been documented among a range of displaced populations, with wide-reaching health and social impacts. Changing agendas in humanitarian response-including increased prominence of mental health and chronic illness-have so far failed to be translated into meaningful interventions for substance use. Methods Studies were conducted from 2006 to 2008 in six different settings of protracted displacement, three in Africa (Kenya, Liberia, northern Uganda) and three in Asia (Iran, Pakistan, and Thailand). We used intervention-oriented qualitative Rapid Assessment and Response methods, adapted from two decades of experience among non-displaced populations. The main sources of data were individual and group interviews conducted with a culturally representative (non-probabilistic) sample of community members and service providers. Results Widespread use of alcohol, particularly artisanally-produced alcohol, in Kenya, Liberia, Uganda, and Thailand, and opiates in Iran and Pakistan was believed by participants to be linked to a range of health, social and protection problems, including illness, injury (intentional and unintentional), gender-based violence, risky behaviour for HIV and other sexually transmitted infection and blood-borne virus transmission, as well as detrimental effects to household economy. Displacement experiences, including dispossession, livelihood restriction, hopelessness and uncertain future may make communities particularly vulnerable to substance use and its impact, and changing social norms and networks (including the surrounding population) may result in changed - and potentially more harmful-patterns of use. Limited access to services, including health services, and exclusion from relevant host population programmes, may exacerbate the harmful consequences. Conclusions The six studies show the feasibility and value of conducting rapid assessments in displaced populations. One outcome of these studies is the development of a UNHCR/WHO field guide on rapid assessment of alcohol and other substance use among conflict-affected populations. More work is required on gathering population-based epidemiological data, and much more experience is required on delivering effective interventions. Presentation of these findings should contribute to increased awareness, improved response, and more vigorous debate around this important but neglected area. PMID:21310092

Experiences of intervertebral motion palpation in osteopathic practice - A qualitative interview study among Swedish osteopaths.

Sposato, Niklas S; Bjerså, Kristofer

2017-01-01

Assessment in manual therapy includes quantitative and qualitative procedures, and intervertebral motion palpation (IMP) is one of the core assessment methods in osteopathic practice. The aim of this study was to explore osteopathic practitioners' experiences of clinical decision-making and IMP as a diagnostic tool for planning and evaluation of osteopathic interventions. The study was conducted with semi-structured interviews that included eight informants. Content analysis was used as the analytical procedure. In total, three categories emerged from the analysis: strategic decision-making, diagnostic usability of IMP, and treatment applicability of IMP. The study indicated that IMP was considered relevant and was given particular importance in cases where IMP findings confirmed clinical information attained from other stages in the diagnostic process as a whole. However, IMP findings were experienced as less important if they were not correlated to other findings. Copyright © 2016 Elsevier Ltd. All rights reserved.

Compton, J. M.

1988-01-01

The results of the Independent Orbiter Assessment (IOA) of the Failure Modes and Effects Analysis (FMEA) and Critical Items List (CIL) are presented. The IOA effort first completed an analysis of the Orbiter Experiments (OEX) hardware, generating draft failure modes and potential critical items. To preserve independence, this analysis was accomplished without reliance upon the results contained within the NASA FMEA/CIL documentation. The IOA results were then compared to the NASA FMEA/CIL baseline with proposed Post 51-L updates included. A resolution of each discrepancy from the comparison is provided through additional analysis as required. The results of that comparison for the Orbiter OEX hardware are documented. The IOA product for the OEX analysis consisted of 82 failure mode worksheets that resulted in two potential critical items being identified.

A content analysis of peripheral arterial disease patient-reported outcome measures using the International Classification of Functioning, Disability and Health.

The purpose of this study was to link, classify and describe the content of peripheral arterial disease (PAD)-specific patient-reported outcome measures using the International Classification of Functioning. The results were then analyzed to determine if these assessments provide clinicians and researchers with a comprehensive understanding of the lived experience of patients with PAD. Each meaningful concept in identified PAD assessments was linked to the International Classification of Functioning, Disability and Health to determine included and excluded content areas. An overall perspective was assigned to each assessment item. Inter-rater reliability was established using a kappa statistic. The body functions component is most frequently addressed overall followed by the activities and participation component. International Classification of Functioning chapter and category distribution vary greatly between assessments and no assessment comprehensively examines community participation and relationships. The majority of the assessment items are of the health status-disability and quality of life perspectives. The results of this study suggest the need for the development of a comprehensive PAD assessment that includes a more even distribution of International Classification of Functioning topics and subtopics. A more comprehensive assessment would better capture the lived experience of this patient population. Implications for Rehabilitation A better understanding of the data collected using the current peripheral arterial disease-specific patient-reported outcome measures may contribute to the development of more comprehensive assessment tools that will ultimately lead to improved patient care. This study contributes to the preliminary foundation for the development of a peripheral arterial disease International Classification of Functioning, Disability and Health Core Set. Clinicians and researchers interested in using peripheral arterial disease-specific patient-reported outcome measures for clinical and research purposes can better understand what topics are included and excluded in the collection and what perspectives are addressed.

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

The aim of the study was to assess schizotypy by using the Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE), in the groups of patients with schizophrenia, bipolar disorder (BD) and unipolar (recurrent) depression (UD). An important element of the study was to compare - in terms of similarity - the results obtained in schizophrenia and BD, and - in terms of differences - the results obtained in BD and UD. The study involved 58 patients with schizophrenia (35 men, 23 women, mean age = 34.0, SD = 9.8), 52 patients with BD (22 men, 30 women, mean age = 40.3, SD = 13.6) and 57 UD patients (24 men, 33 women, mean age = 50.2, SD = 11.9), treated in the Department of Adult Psychiatry, Poznan University of Medical Sciences. For the assessment of schizotypy, the full version of the O-LIFE questionnaire (104 questions) was used, including such dimensions as: unusual experiences, cognitive disorganization, introvertive anhedonia and impulsive nonconformity. The biggest differences between diagnostic groups were found in the dimensions of unusual experiences and impulsive nonconformity. Similarities between schizophrenia and BD were found for unusual experiences, cognitive disorganization and introvertive anhedonia. Differences between BD and UD were obtained for unusual experiences and impulsive nonconformity. The assessment of schizotypy in three diagnostic groups (it was the first study in patients with UD), allowed to address contemporary pathogenic and clinical concepts pertaining to similarities between schizophrenia and BD as well as to differences between two types of affective disorders.

2014-04-01

Genetic modification of plants may result in unintended effects causing potentially adverse effects on the environment. A comparative safety assessment is therefore required by authorities, such as the European Food Safety Authority, in which the genetically modified plant is compared with its conventional counterpart. Part of the environmental risk assessment is a comparative field experiment in which the effect on non-target organisms is compared. Statistical analysis of such trials come in two flavors: difference testing and equivalence testing. It is important to know the statistical properties of these, for example, the power to detect environmental change of a given magnitude, before the start of an experiment. Such prospective power analysis can best be studied by means of a statistical simulation model. This paper describes a general framework for simulating data typically encountered in environmental risk assessment of genetically modified plants. The simulation model, available as Supplementary Material, can be used to generate count data having different statistical distributions possibly with excess-zeros. In addition the model employs completely randomized or randomized block experiments, can be used to simulate single or multiple trials across environments, enables genotype by environment interaction by adding random variety effects, and finally includes repeated measures in time following a constant, linear or quadratic pattern in time possibly with some form of autocorrelation. The model also allows to add a set of reference varieties to the GM plants and its comparator to assess the natural variation which can then be used to set limits of concern for equivalence testing. The different count distributions are described in some detail and some examples of how to use the simulation model to study various aspects, including a prospective power analysis, are provided.

Adverse childhood experiences in children with autism spectrum disorder.

PubMed

Hoover, Daniel W; Kaufman, Joan

2018-03-01

Recent years have shown an uptick in studies assessing bullying and other adverse childhood experiences (ACEs) in children with autism spectrum disorder (ASD). This article reviews extant findings, and points to gaps in the literature. Children with ASD are bullied by peers at a rate three to four times that of nondisabled peers with negative impacts on academic functioning and mental health symptoms, including increased risk for suicidality. Children with ASD are also at enhanced risk for other ACES, particularly parental divorce and income insufficiency, and as observed in the general population, children with ASD who experience an increased number of ACES are at elevated risk for comorbid psychiatric and medical health problems. Children with ASD with an elevated number of ACES also experience a delay in ASD diagnosis and treatment initiation. There is no evidence of increased risk of child maltreatment within the ASD population. As bullying and other adverse experiences are common and associated with deleterious outcomes in children with ASD, there is a need for additional research on intervention strategies to prevent and mitigate the impact of these experiences. Ongoing work on the assessment of trauma experiences and PTSD symptoms in children on the spectrum is also needed.

Results are presented from the experiments conducted by the first Shuttle/Spacelab mission dedicated entirely to the life sciences, the Spacelab Life Sciences 1, launched on June 5, 1991. The experiments carried out during the 9-day flight included investigations of changes in the human cardiovascular, pulmonary, renal/endocrine, blood, and vestibular systems that were brought about by microgravity. Results were also obtained from the preflight and postflight complementary experiments performed on rats, which assessed the suitability of rodents as animal models for humans. Most results verified, or expanded on, the accepted theories of adaptation to zero gravity.

Not that neglected! Base rates influence related and unrelated judgments.

Białek, Michał

2017-06-01

It is claimed that people are unable (or unwilling) to incorporate prior probabilities into posterior assessments, such as their estimation of the likelihood of a person with characteristics typical of an engineer actually being an engineer given that they are drawn from a sample including a very small number of engineers. This paper shows that base rates are incorporated in classifications (Experiment 1) and, moreover, that base rates also affect unrelated judgments, such as how well a provided description of a person fits a stereotypical engineer (Experiment 2). Finally, Experiment 3 shows that individuals who make both types of assessments - though using base rates to the same extent in the former judgments - are able to decrease the extent to which they incorporate base rates in the latter judgments.

This study examined whether childhood bullying victimization was associated with psychosocial and academic functioning at college. The sample consisted of 413 first-year students from a large northeastern university. Students completed an online survey in February 2012 that included items assessing past bullying involvement, current psychosocial and academic functioning, and victimization experiences since arriving at college. Regression analyses indicated that reports of past bullying and other peer victimization were associated with lower mental health functioning and perceptions of physical and mental health, but were not associated with perceptions of social life at college, overall college experience, or academic performance. Childhood bullying victimization is associated with poorer mental and physical health among first-year college students. Colleges should consider assessing histories of bullying victimization, along with other past victimization exposures, in their service provision to students.

Recent examples of high-impact teaching practices in the undergraduate chemistry laboratory that include course-based undergraduate research experiences and inquiry-based experiments require new approaches to assessing individual student learning outcomes. Instructors require tools and strategies that can provide them with insight into individual student contributions to collaborative group/teamwork throughout the processes of experimental design, data analysis, display and communication of their outcomes in relation to their research question(s). Traditional assessments in the form of laboratory notebooks or experimental reports provide limited insight into the processes of collaborative inquiry-based activities. A wiki environment offers a collaborative domain that can potentially support collaborative laboratory processes and scientific record keeping. In this study, the effectiveness of the wiki in supporting laboratory learning and assessment has been evaluated through analysis of the content and histories for three consenting, participating groups of students. The conversational framework has been applied to map the relationships between the instructor, tutor, students and laboratory activities. Analytics that have been applied to the wiki platform include: character counts, page views, edits, timelines and the extent and nature of the contribution by each student to the wiki. Student perceptions of both the role and the impact of the wiki on their experiences and processes have also been collected. Evidence has emerged from this study that the wiki environment has enhanced co-construction of understanding of both the experimental process and subsequent communication of outcomes and data. A number of features are identified to support success in the use of the wiki platform for laboratory notebooks.

A research program to assess the impact of the electromagnetic pulse on electric power systems

NASA Astrophysics Data System (ADS)

McConnell, B. W.; Barnes, P. R.

A strong electromagnetic pulse (EMP) with an electric-field component on the order of tens of kilovolts per meter is produced by a nuclear detonation in or above the atmosphere. This paper presents an overview and a summary of the results to date of a program formulated to address the research and development of technologies and systems required to assess and reduce the impact of EMP on electric power systems. The technologies and systems being considered include simulation models, methods of assessment, definition of required experiments and data, development of protective hardware, and the creation or revision of operating and control procedures. Results to date include the development of relatively simple unclassified EMP environment models, the development of methods for extending EMP coupling models to the large transmission and distribution network associated with the electric power system, and the performance of a parametric study of HEMP induced surges using an appropriate EMP environment. An experiment to investigate the effect of corona on the coupling of EMP to conductors has been defined and has been performed in an EMP simulator. Experiments to determine the response of key components to simulated EMP surges and an investigation of the impact of steep-front, short-duration impulse on a selected number of the insulation systems used in electric power systems apparatus are being performed.

The analysis of similarities and differences of parental experience of observing preterm versus full term babies assessed with the Neonatal Behavioural Assessment Scale (NBAS). 95 pairs of parents participated in the study, including 33 mothers and fathers of babies born before 29th gestational week, 31 - between 29th and 34th week and 31 - at term. All infants were assessed with the NBAS in the first month of life (or corrected age) in the presence of both parents. Semi-structured clinical interviews were conducted with each parental pair and the qualitative analysis of the obtained co-constructed narratives was carried out. Seven common categories of parental experience related to the NBAS were empirically discerned in all groups of parents. There were also two categories of experience related to the NBAS that were different in the group of parents of preterm versus full term babies. Apart from that, three specific categories characteristic of the parental narratives in the two preterm groups were identified: parental tendency to compare NBAS assessment with medical examination, hope for having the child's health confirmed and parental tendency to compare preterm with full term babies. Mothers and fathers of preterm vs full term babies experience the observation of NBAS assessment differently. Parents of preterm babies are extremely sensitive to any information regarding their child. Therefore specialists should pay a special attention to the process of communicating with the family. Effective support of any family in the perinatal period requires special appreciation of the individual parental needs.

Objectives. We assessed whether adequate sleep is linked to more healthful eating behaviors among motor freight workers and whether it mediates the effects of workplace experiences. Methods. Data were derived from a baseline survey and assessment of permanent employees at 8 trucking terminals. Bivariate and multivariate regression models were used to examine relationships between work environment, sleep adequacy, and dietary choices. Results. The sample (n = 542) was 83% White, with a mean age of 49 years and a mean body mass index of 30 kg/m2. Most of the participants were satisfied with their job (87.5%) and reported adequate sleep (51%); 30% reported job strain. In our first model, lack of job strain and greater supervisor support were significantly associated with adequate sleep. In our second model, educational level, age, and adequate sleep were significantly associated with at least 2 of the 3 healthful eating choices assessed (P < .05). However, work experiences were not significant predictors of healthful food choices when adequate sleep was included. Conclusions. Adequate sleep is associated with more healthful food choices and may mediate the effects of workplace experiences. Thus, workplace health programs should be responsive to workers' sleep patterns.

The objective of this study is to determine the ability of the GEARS scale (Global Evaluative Assessment of Robotic Skills) to differentiate individuals with different levels of experience in robotic surgery, as a fundamental validation. This is a cross-sectional study that included three groups of individuals with different levels of experience in robotic surgery (expert, intermediate, novice) their performance were assessed by GEARS applied by two reviewers. The difference between groups was determined by Mann-Whitney test and the consistency between the reviewers was studied by Kendall W coefficient. The agreement between the reviewers of the scale GEARS was 0.96. The score was 29.8 ± 0.4 to experts, 24 ± 2.8 to intermediates and 16 ± 3 to novices, with a statistically significant difference between all of them (p < 0.05). All parameters from the scale allow discriminating between different levels of experience, with exception of the depth perception item. We conclude that the scale GEARS was able to differentiate between individuals with different levels of experience in robotic surgery and, therefore, is a validated and useful tool to evaluate surgeons in training.

Goals and Status of the NASA Juncture Flow Experiment

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.

2006-01-01

SUMMARY In order to characterize undesirable behavior (drug use, fighting, criminal activity) among Haitian youth at risk and determine the relationship between traumatic experience and that kind of behavior, investigators recruited 291 Haitian youths via networks of informal social relations in two zones of Miami/Dade County strongly idenitified with Haitian ethnicity. Each recruit responded to an interview schedule eliciting sociodemographic information and self-reported activities, including involvement in youth-dominated groups. They also reported traumatic experience. Clinicians administered CAPS to a subset of those respondents who self-reported traumatic experience. Staff ethnographers selected respondents for in-depth interviews and family studies to provide contextual depth for findings of the interview schedule and the CAPS assessments. Although traumatic experience may still play a role in mental health outcomes among children, childhood victimization among Haitian children does not appear to be related to the drug use and undesirable behaviors associated with unsupervised youth, including formation of gangs.

Keeler, Amanda R; Siegel, Jason T

2016-09-15

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

2016-06-21

Stress assessments are due to be conducted in December 2015. It is expected that there will be an increase in the number of private health agencies that provide stress assessment services and mental health care. This study aimed to clarify the current situation of and the factors related to stress assessments conducted by nurses in occupational health agencies. Nurses working full time were randomly selected from 60 organizations that were members of the National Federation of Industrial Health Organization. Self-administered questionnaires were sent out between November 2013 and January 2014. The questionnaire included the personal attributes of the participants, training programs, job contents, and how practical mental health care, including stress assessment, is. The study was approved by the ethics committees in the respective organizations. Out of the 162 questionnaires that were distributed, 89 (54.9%) were returned and 85 (53.1%) were valid for analysis. Stress assessments were conducted by 38.8% of the participants. With reference to their confidence in conducting stress assessments, "confidence and" 70.6%, respectively. The groups that conducted and did not conduct the stress assessments did not show any differences in the findings or other attributes. Further, the implementation of stress assessment was not associated with occupational health nurse (OHN) training, education, position, age, years of experience, attendance of lectures on mental health, etc. However, the confidence in conducting the assessment was related to age when dealing with cases on confidence stress assessment consultation in follow-up to the implementation of screening, such as stress, persons at high risk, and so on. Approximately 40% of the nurses were already conducting stress assessments, but most of them conducted such assessments about once a year and were not deeply involved in them. Approximately 70% of the nurses were confident in implementing stress assessments. Further, they reported that they were confident to do so even if OHNs were not involved. We found that to encourage OHNs in occupational health agencies to provide mental health care and stress assessments, practical training programs are required. Such programs should include a series of stress assessments and help foster cooperation with superiors, colleagues, and occupational health staff such that the OHNs obtain experience and confidence.

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

The ecological risks of genetically engineered organisms

NASA Astrophysics Data System (ADS)

Wolfenbarger, Lareesa

2001-03-01

Highly publicized studies have suggested environmental risks of releasing genetically engineered organisms (GEOs) and have renewed concerns over the evaluation and regulation of these products in domestic and international arenas. I present an overview of the risks of GEOs and the available evidence addressing these and discuss the challenges for risk assessment. Main categories of risk include non-target effects from GEOs, emergence of new viral diseases, and the spread of invasive (weedy) characteristics. Studies have detected non-target effects in some cases but not all; however, much less information exists on other risks, in part due to a lack of conceptual knowledge. For example, general models for predicting invasiveness are not well developed for any introduced organism. The risks of GEOs appear comparable to those for any introduced species or organism, but the magnitude of the risk or the pathway of exposure to the risk can differ among introduced organisms. Therefore, assessing the risks requires a case-by-case analysis so that any differences can be identified. Challenges to assessing risks to valued ecosystems include variability in effects and ecosystem complexity. Ecosystems are a dynamic and complex network of biological and physical interactions. Introducing a new biological entity, such as a GEO, may potentially alter any of these interactions, but evaluating all of these is unrealistic. Effects on a valued ecosystem could vary greatly depending on the geographical location of the experimental site, the GEO used, the plot size of the experiment (scaling effects), and the biological and physical parameters used in the experiment. Experiments that address these sources of variability will provide the most useful information for risk assessments.

This article shares the experiences, observations, and discussions that occurred during the completing of an ecosystem services (ES) indicator framework to be used at European Union (EU) and Member States' level. The experience base was drawn from 3 European research projects and 14 associated case study sites that include 13 transitional-water bodies (specifically 8 coastal lagoons, 4 riverine estuaries, and 1 fjord) and 1 coastal-water ecosystem. The ES pertinent to each case study site were identified along with indicators of these ES and data sources that could be used for mapping. During the process, several questions and uncertainties arose, followed by discussion, leading to these main lessons learned: 1) ES identification: Some ES that do not seem important at the European scale emerge as relevant at regional or local scales; 2) ES indicators: When direct indicators are not available, proxies for indicators (indirect indicators) might be used, including combined data on monitoring requirements imposed by EU legislation and international agreements; 3) ES mapping: Boundaries and appropriate data spatial resolution must be established because ES can be mapped at different temporal and spatial scales. We also acknowledge that mapping and assessment of ES supports the dialogue between human well-being and ecological status. From an evidence-based marine planning-process point of view, mapping and assessment of marine ES are of paramount importance to sustainable use of marine natural capital and to halt the loss of marine biodiversity.

Assessing yourself as an emotional eater: mission impossible?

PubMed

Evers, Catharine; de Ridder, Denise T D; Adriaanse, Marieke A

2009-11-01

The extent to which individuals are emotional eaters has typically been assessed by people's self-reported desire to eat when they experience negative emotions. Elevated scores on these emotional eater scales have been associated with eating pathology and obesity. However, evidence that individuals scoring high on these scales truly increase their food intake during emotional encounters is inconclusive. The current studies tested whether emotional eater scales capture the proposed tendency to eat when feeling emotional. In four experiments with different emotion induction procedures, female participants were randomly assigned to negative emotion or control conditions. In the control conditions positive or no emotions were induced. Next, food consumption was assessed by bogus taste tests. Emotional eater status, emotional experience, and actual consumption of different food types. Individuals describing themselves as emotional eaters did not increase food intake during emotional encounters as compared to control conditions or individuals not judging themselves as emotional eaters. The results suggest that self-reported emotional eaters do not increase food intake during emotional encounters in the laboratory. Implications of these findings are discussed, including the idea that it may be complex to adequately assess one's own emotional eating behavior.

Grieving experiences amongst adolescents orphaned by AIDS: Analysis from event history calendars.

PubMed

Thupayagale-Tshweneagae, Gloria

2012-09-07

Mental health is an essential component of adolescent health and wellbeing. Mental health practitioners assess adolescents' mental health status to identify possible issues that may lead to mental health problems. However, very few of the tools used to assess the mental health status of adolescents include assessment for grieving and coping patterns. The current tools used for assessing an individual's mental health are lengthy and not comprehensive. The purpose of this study was to assess grieving patterns of adolescents orphaned by AIDS and to appraise the usefulness of an event history calendar as an assessment tool for identifying grieving experiences, in order to guide and support these adolescents through the grieving process. One hundred and two adolescents aged 14-18 years, who had been orphaned by AIDS, completed an event history calendar, reviewed it with the researcher and reported their perceptions of it. Thematic analysis of the event history calendar content revealed that it is an effective, time-efficient, adolescent-friendly tool that facilitated identification and discussion of the orphaned adolescents' grieving patterns. Crying, isolation, silence and violent outbursts were the main grieving patterns reported by adolescents orphaned by AIDS. The researcher recommends use of the event history calendar for identification of orphaned adolescents' grieving experiences. Early identification would enable mental health practitioners to support them in order to prevent the occurrence of mental illness due to maladaptive grieving.

Geologic signatures of atmospheric effects on impact cratering on Venus

NASA Technical Reports Server (NTRS)

1996-01-01

Highlights of the research include geologic signatures of impact energy and atmospheric response to crater formation. Laboratory experiments were performed at the NASA Ames Vertical Gun Range (AVGR) to assess the interaction between disrupted impactor and atmosphere during entry, and to assess the energy coupling between impacts and the surrounding atmosphere. The Schlieren imaging at the AVGR was used in combination with Magellan imaging and theoretical studies to study the evolution of the impactor following impact. The Schlieren imaging documented the downrange blast front created by vaporization during oblique impacts. Laboratory experiments allowed assessing the effect of impact angle on coupling efficiency with an atmosphere. And the impact angle's effect on surface blasts and run-out flows allowed the distinction of crater clusters created by simultaneous impacts from those created by isolated regions of older age.

Arbour, Richard

2003-01-01

Practice concerns associated with the medical prescription and nurses' administration and monitoring of sedatives, analgesics, and neuromuscular blocking agents were identified by the clinical nurse specialist within a surgical intensive care unit of a large, tertiary-care referral center. These concerns were identified using a variety of needs assessment strategies. Results of the needs assessment were used to develop a program of care, including a teaching initiative, specific to these practice areas. The teaching initiative incorporated principles of andragogy, the theory of adult learning. Educational techniques included inservice education, bedside instruction using "teaching moments," competency-based education modules, and integration of instruction into critical care orientation. Content and approach were based on the background and level of experience of participants. Educational program outcomes included increased consistency in monitoring neuromuscular blockade by clinical assessment and peripheral nerve stimulation. A second outcome was more accurate patient assessment leading to the provision of drug therapy specific to the patients' clinical states, including anxiety or pain. The continuous quality improvement approach offers a model for improving patient care using individualized needs assessment, focused educational interventions, and program evaluation strategies.

2017-08-01

Laser cutting of various materials including Ti-6Al-4V alloy, steel 304, Inconel 625, and alumina is carried out to assess the kerf width size variation along the cut section. The life cycle assessment is carried out to determine the environmental impact of the laser cutting in terms of the material waste during the cutting process. The kerf width size is formulated and predicted using the lump parameter analysis and it is measured from the experiments. The influence of laser output power and laser cutting speed on the kerf width size variation is analyzed using the analytical tools including scanning electron and optical microscopes. In the experiments, high pressure nitrogen assisting gas is used to prevent oxidation reactions in the cutting section. It is found that the kerf width size predicted from the lump parameter analysis agrees well with the experimental data. The kerf width size variation increases with increasing laser output power. However, this behavior reverses with increasing laser cutting speed. The life cycle assessment reveals that material selection for laser cutting is critical for the environmental protection point of view. Inconel 625 contributes the most to the environmental damages; however, recycling of the waste of the laser cutting reduces this contribution.

Cumulative stress in research animals: Telomere attrition as a biomarker in a welfare context?

PubMed

Bateson, Melissa

2016-02-01

Progress in improving animal welfare is currently limited by the lack of objective methods for assessing lifetime experience. I propose that telomere attrition, a cellular biomarker of biological age, provides a molecular measure of cumulative experience that could be used to assess the welfare impact of husbandry regimes and/or experimental procedures on non-human animals. I review evidence from humans that telomere attrition is accelerated by negative experiences in a cumulative and dose-dependent manner, but that this attrition can be mitigated or even reversed by positive life-style interventions. Evidence from non-human animals suggests that despite some specific differences in telomere biology, stress-induced telomere attrition is a robust phenomenon, occurring in a range of species including mice and chickens. I conclude that telomere attrition apparently integrates positive and negative experience in an accessible common currency that translates readily to novel species--the Holy Grail of a cumulative welfare indicator. © 2015 The Author.

Biomass burning, including wildfires and prescribed burns, strongly impact the global carbon cycle and are of increasing concern due to the potential impacts on ambient air quality. This modelling study focuses on the evolution of carbonaceous compounds during a prescribed burning experiment and assesses the impacts of burning on local to regional air quality. The Community Multiscale Air Quality (CMAQ) model is used to conduct 4 and 2 km grid resolution simulations of prescribed burning experiments in southeast Washington state and western Idaho state in summer 2013. The ground and airborne measurements from the field experiment are used to evaluate the model performance in capturing surface and aloft impacts from the burning events. Phase partitioning of organic compounds in the plume are studied as it is a crucial step towards understanding the fate of carbonaceous compounds. The sensitivities of ambient concentrations and deposition to emissions are conducted for organic carbon, elemental carbon and ozone to estimate the impacts of fire on air quality.

Assessing the relationship between latent inhibition and the partial reinforcement extinction effect in autoshaping with rats.

PubMed

Boughner, Robert L; Papini, Mauricio R

2008-05-01

Results from a variety of independently run experiments suggest that latent inhibition (LI) and the partial reinforcement extinction effect (PREE) share underlying mechanisms. Experiment 1 tested this LI=PREE hypothesis by training the same set of rats in situations involving both nonreinforced preexposure to the conditioned stimulus (LI stage) and partial reinforcement training (PREE stage). Control groups were also included to assess both LI and the PREE. The results demonstrated a significant, but negative correlation between the size of the LI effect and that of the PREE. Experiment 2 extended this analysis to the effects on LI and the PREE of the anxiolytic benzodiazepine chlordiazepoxide (5 mg/kg, i.p.). Whereas chlordiazepoxide had no effect on LI, it delayed the onset of the PREE. No evidence in support of the LI=PREE hypothesis was obtained when these two learning phenomena were compared within the same experiment and under the same general conditions of training.

Neurofibromatosis Type 1 (NF1) may have many psychosocial consequences for affected adults. More knowledge is needed about the experience of psychosocial aspects in different stages of adulthood. This qualitative study aims to describe the experiences and concerns of persons living with NF1 in the early stages of adulthood. In semi-structured interviews, Norwegian adults with NF1 (n = 15) between 18 and 37 years of age described their experiences and concerns. Interview transcripts were analysed in a both concept and data driven way. Severity of NF1 was assessed from interview data. Our data indicate that many informants have more friends than in childhood, including friends with NF1. An important topic is whether or not to inform others about the NF1 diagnosis . Low self-confidence is common, often related to early school failure and bullying or to visible neurofibromas. The unpredictable development of NF1 causes much concern. The experience of NF1's impact seems less associated with the assessed severity than with social network, relation to the labour market, and psychological factors.

Refugees can suffer many experiences that threaten their trust in others. Although models of refugee mental health have postulated that attachment securities may be damaged by refugee experiences, this has yet to be empirically tested. This study aimed to understand the relationship between the nature of traumatic experiences sustained by refugees and attachment styles. In a cross-sectional study, treatment-seeking refugees (N = 134) were assessed for traumatic exposure using the Harvard Trauma Questionnaire and Posttraumatic Diagnostic Scale. Attachment style was assessed using the Experiences in Close Relationship Scale. Whereas gender and severity of interpersonal traumatic events predicted avoidant attachment style (accounting for 11% of the variance), neither these factors nor non-interpersonal trauma predicted anxious attachment. Exposure to interpersonal traumatic events, including torture, is associated with enduring avoidant attachment tendencies in refugees. This finding accords with attachment theories that prior adverse interpersonal experiences can undermine secure attachment systems, and may promote avoidance of attachment seeking. This finding may point to an important process maintaining poor psychological health in refugees affected by interpersonal trauma. © The Royal Australian and New Zealand College of Psychiatrists 2016.

Overcoming future difficulties in searching for ore deposits deeper in the earth's crust will require closer attention to the collection and analysis of more diverse types of data and to more efficient use of current computer technologies. Computer technologies of greatest interest include methods of storage and retrieval of resource information, methods for integrating geologic, geochemical, and geophysical data, and the introduction of advanced computer technologies such as expert systems, multivariate techniques, and neural networks. Much experience has been gained in the past few years in applying these technologies. More experience is needed if they are to be implemented for everyday use in future assessments and exploration.

The goal of this research was to define a measure of situation awareness (SA) in an air traffic control (ATC) task and to assess the influence of adaptive automation (AA) of various information processing functions on controller perception, comprehension and projection. The measure was also to serve as a basis for defining and developing an approach to triggering dynamic control allocations, as part of AA, based on controller SA. To achieve these objectives, an enhanced version of an ATC simulation (Multitask (copyright)) was developed for use in two human factors experiments. The simulation captured the basic functions of Terminal Radar Approach Control (TRACON) and was capable of presenting to operators four different modes of control, including information acquisition, information analysis, decision making and action implementation automation, as well as a completely manual control mode. The SA measure that was developed as part of the research was based on the Situation Awareness Global Assessment Technique (SAGAT), previous goal-directed task analyses of enroute control and TRACON, and a separate cognitive task analysis on the ATC simulation. The results of the analysis on Multitask were used as a basis for formulating SA queries as part of the SAGAT-based approach to measuring controller SA, which was used in the experiments. A total of 16 subjects were recruited for both experiments. Half the subjects were used in Experiment #1, which focused on assessing the sensitivity and reliability of the SA measurement approach in the ATC simulation. Comparisons were made of manual versus automated control. The remaining subjects were used in the second experiment, which was intended to more completely describe the SA implications of AA applied to specific controller information processing functions, and to describe how the measure could ultimately serve as a trigger of dynamic function allocations in the application of AA to ATC. Comparisons were made of the sensitivity of the SA measure to automation manipulations impacting both higher-order information processing functions, such as information analysis and decision making, versus lower-order functions, including information acquisition and action implementation. All subjects were exposed to all forms of AA of the ATC task and the manual control condition. The approach to AA used in both experiments was to match operator workload, assessed using a secondary task, to dynamic control allocations in the primary task. In total, the subjects in each experiment participated in 10 trials with each lasting between 45 minutes and 1 hour. In both experiments, ATC performance was measured in terms of aircraft cleared, conflicting, and collided. Secondary task (gauge monitoring) performance was assessed in terms of a hit-to-signal ratio. As part of the SA measure, three simulation freezes were conducted during each trial to administer queries on Level 1, 2, and 3 SA.

The skills and experience of GRADE methodologists can be assessed with a simple tool.

To suggest approaches for guideline developers on how to assess a methodologist's expertise with Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods and tasks and to provide a set of minimum skills and experience required to perform specific tasks related to guideline development using GRADE. We used an iterative and consensus-based process involving individuals with in-depth experience with GRADE. We considered four main tasks: (1) development of key questions; (2) assessment of the certainty of effect estimates; (3) development of recommendations; and (4) teaching GRADE. There are three basic approaches to determine a methodologist's skill set. First, self-report of knowledge, skills, and experience with a standardized "GRADE curriculum vitae (CV)" focused on each of the GRADE-related tasks; second, demonstration of skills using worked examples; third, a formal evaluation using a written or oral test. We suggest that the GRADE CV is likely to be useful and feasible to implement. We also suggest minimum training including attendance at one or more full-day workshops and familiarity with the main GRADE publications and the GRADE handbook. The selection of a GRADE methodologist must be a thoughtful, reasoned decision, informed by the criteria suggested in this article and tailored to the specific project. Our suggested approaches need further pilot testing and validation. Copyright © 2016 Elsevier Inc. All rights reserved.

Parental involvement in their school-aged children's post-operative pain management in the hospital setting: a comprehensive systematic review.

PubMed

Hoon, Lim Siew; Hong-Gu, He; Mackey, Sandra

Paediatric pain management remains a challenge in clinical settings. Parents can contribute to the effective and accurate pain assessment and management of their child. No systematic reviews regarding the parental involvement in their child's post-operative pain management have been published. To determine the best available evidence regarding parental involvement in managing their children's post-operative pain in the hospital setting. The review considered studies that included parents of all ethnic groups with children aged between 6 to 12 years old who were hospitalised and undergone surgery of any kind with post-operative surgical or incision site pain where care was provided in acute hospital settings. The phenomena of interest were the experiences of parents in managing their children's post-operative pain. A three-step search strategy was utilised in each component of this review. Major databases searched included: MEDLINE, CINAHL, Scopus, ScienceDirect, the Cochrane library, PubMed as well as Google Scholar. The search included published studies and papers in English from 1990 to 2009. Each included study was assessed by two independent reviewers using the appropriate appraisal checklists developed by the Joanna Briggs Institute (JBI). Quantitative and qualitative data were extracted from the included papers using standardised data extraction tools from the JBI, Meta-analysis Statistics Assessment and Review Instrument data extraction tool for descriptive/case series and the JBI-Qualitative Assessment and Review Instrument data extraction tool for interpretive and critical research. The five quantitative studies included in this review were not suitable for meta-analysis due to clinical and methodological heterogeneity and therefore the findings are presented in a narrative form. The two qualitative studies were from the same study, therefore meta-synthesis was not possible. Hence the results of the studies were presented in a narrative format. Seven papers were included in this review. The evidence identified topics including: pharmacological and non-pharmacological interventions carried out by parents; the experience of concern, fear, helplessness, anxiety, depression, frustration and lack of support felt by parents during their child's hospitalisation; communication issues and knowledge deficits; need for information by parents to promote effective participation in managing their child's post-operative pain. This review revealed pharmacological and non-pharmacological interventions carried out by parents to alleviate their children's post-operative pain. Obstacles and promoting factors influencing parents' experiences as well as their needs in the process of caring were identified. Parents' roles in their child's surgical pain management should be clarified and their efforts acknowledged, which will encourage parents' active participation in their child's caring process. Nurses should provide guidance, education and support to parents. More studies are needed to examine parents' experiences in caring for their child, investigate the effectiveness of education and guidance provided to parents by the nurses and explore the influence of parents' cultural values and nurses' perceptions of parental participation in their child's care.

Group therapies are routinely provided for patients with severe mental illness. The factors important to the group experience of patients are still poorly understood and are rarely measured. To support further research and practice, we aimed to develop a questionnaire that captures how patients experience groups within a community mental health context. An initial pool of 39 items was conceptually generated to assess different aspects of group experiences. Items were completed by 166 patients with severe mental illness attending group therapies in community mental health services in Italy. Patients with different psychiatric diagnoses who attended at least 5 group sessions were included. An exploratory factor analysis was used to identify different dimensions of group experiences and to reduce the number of items for each dimension. The resulting questionnaire has five subscales: 1) sharing of emotions and experiences, 2) cognitive improvement, 3) group learning, 4) difficulties in open expression and 5) relationships. Each subscale has 4 items. The scale and sub-scales have good internal consistency. The Ferrara Group Experiences Scale is conceptually derived and assesses dimensions of group experience that are theoretically and practically relevant. It is brief, easy to use and has good psychometric properties. After further validation, the scale may be used for research into patient experiences across different group therapy modalities and for evaluation in routine care.

Abstract Background: Wellness retreats use many complementary and alternative therapies within a holistic residential setting, yet few studies have evaluated the effect of retreat experiences on multiple dimensions of health and well-being, and no published studies have reported health outcomes in wellness tourists. Objectives: To assess the effect of a week-long wellness-retreat experience in wellness tourists. Design: A longitudinal observational study with outcomes assessed upon arrival and departure and 6 weeks after the retreat. Setting: A rural health retreat in Queensland, Australia. Interventions: A holistic, 1-week, residential, retreat experience that included many educational, therapeutic, and leisure activities and an organic, mostly plant-based diet. Outcome measures: Multiple outcome measures were performed upon arrival and departure and 6 weeks after the retreat. These included anthropometric measures, urinary pesticide metabolites, a food and health symptom questionnaire, the Five Factor Wellness Inventory, the General Self Efficacy questionnaire, the Pittsburgh Insomnia Rating Scale, the Depression Anxiety Stress Scale, the Profile of Mood States, and the Cogstate cognitive function test battery. Results: Statistically significant improvements (p < 0.05) were seen in almost all measures (n = 37) after 1 week and were sustained at 6 weeks (n = 17). There were statistically significant improvements (p < 0.001) in all anthropometric measures after 1 week, with reductions in abdominal girth (2.7 cm), weight (1.6 kg), and average systolic and diastolic pressure (−16.1 mmHg and −9.3 mmHg, respectively). Statistically significant improvements (p < 0.05) were also seen in psychological and health symptom measures. Urinary pesticide metabolites were detected in pooled urine samples before the retreat and were undetectable after the retreat. Conclusion: Retreat experiences can lead to substantial improvements in multiple dimensions of health and well-being that are maintained for 6 weeks. Further research that includes objective biomarkers and economic measures in different populations is required to determine the mechanisms of these effects and assess the value and relevance of retreat experiences to clinicians and health insurers.

Although law is established on a strong presumption that persons younger than a certain age are not competent to consent, statutory age limits for asking children's consent to clinical research differ widely internationally. From a clinical perspective, competence is assumed to involve many factors including the developmental stage, the influence of parents and peers, and life experience. We examined potential determining factors for children's competence to consent to clinical research and to what extent they explain the variation in competence judgments. From January 1, 2012 through January 1, 2014, pediatric patients aged 6 to 18 years, eligible for clinical research studies were enrolled prospectively at various in- and outpatient pediatric departments. Children's competence to consent was assessed by MacArthur Competence Assessment Tool for Clinical Research. Potential determining child variables included age, gender, intelligence, disease experience, ethnicity and socio-economic status (SES). We used logistic regression analysis and change in explained variance in competence judgments to quantify the contribution of a child variable to the total explained variance. Contextual factors included risk and complexity of the decision to participate, parental competence judgment and the child's or parents decision to participate. Out of 209 eligible patients, 161 were included (mean age, 10.6 years, 47.2 % male). Age, SES, intelligence, ethnicity, complexity, parental competence judgment and trial participation were univariately associated with competence (P < 0.05). Total explained variance in competence judgments was 71.5 %. Only age and intelligence significantly and independently explained the variance in competence judgments, explaining 56.6 % and 12.7 % of the total variance respectively. SES, male gender, disease experience and ethnicity each explained less than 1 % of the variance in competence judgments. Contextual factors together explained an extra 2.8 % (P > 0.05). Age is the factor that explaines most of to the variance in children's competence to consent, followed by intelligence. Experience with disease did not affect competence in this study, nor did other variables.

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.

Experience sampling and ecological momentary assessment studies in psychopharmacology: A systematic review.

Experience sampling methods (ESM) and ecological momentary assessment (EMA) offer insight into daily life experiences, including symptoms of mental disorders. The application of ESM/EMA in psychopharmacology can be a valuable addition to more traditional measures such as retrospective self-report questionnaires because they may help reveal the impact of psychotropic medication on patients' actual experiences. In this paper we systematically review the existing literature on the use of ESM/EMA in psychopharmacology research. To this end, we searched the PsycInfo and Medline databases for all available ESM/EMA studies on the use of psychotropic medication in patients with DSM-III-R and DSM-IV disorders. Dissertations were excluded. We included 18 studies that applied ESM/EMA to study the effects of medication on patients with major depressive disorder, substance use disorder, attention-deficit hyperactivity disorder, psychotic disorder, and anxiety disorder. We found that ESM/EMA may allow researchers and clinicians to track patients during different phases of treatment: before treatment to predict outcome, during treatment to examine the effects of treatment on symptoms and different aspects of daily life experience, and after treatment to detect vulnerability for relapse. Moreover, ESM/EMA can potentially help determine how long and in what contexts medications are effective. Thus, ESM/EMA may benefit both researchers and clinicians and might prove to be an effective tool for improving the treatment of psychiatric patients. Copyright © 2015 Elsevier B.V. and ECNP.

Critical interdisciplinary research skills include effective communication with diverse disciplines and cultivating collaborative relationships. Acquiring these skills during graduate education may foster future interdisciplinary research quality and productivity. The project aim was to develop and evaluate an interactive Toolbox workshop approach within an interprofessional graduate level course to enhance student learning and skill in interdisciplinary research. We sought to examine the student experience of integrating the Toolbox workshop in modular format over the duration of a 14-week course. The Toolbox Health Sciences Instrument includes six modules that were introduced in a 110-minute dialogue session during the first class and then integrated into the course in a series of six individual workshops in three phases over the course of the semester. Seventeen students participated; the majority were nursing students. Three measures were used to assess project outcomes: pre-post intervention Toolbox survey, competency self-assessment, and a postcourse survey. All measures indicated the objectives were met by a change in survey responses, improved competencies, and favorable experience of the Toolbox modular intervention. Our experience indicates that incorporating this Toolbox modular approach into research curricula can enhance individual level scientific capacity, future interdisciplinary research project success, and ultimately impact on practice and policy. © 2015 Wiley Periodicals, Inc.

To compare and contrast experiential education perceptions of pharmacy residency program directors (RPDs) and doctor of pharmacy students in their last year of the curriculum for residency application considerations. The New England Regional Departments of Experiential Education (NERDEE) consortium developed a 17-question survey to assess residency factors, including those related to experiential education. The survey was dispersed to advanced pharmacy practice experience (APPE) students from six colleges/schools of pharmacy and RPDs nationwide. Students have different values on experiential preferences compared to RPDs. Sample findings include internal medicine and specialty clinical elective experiences prior to American Society of Health-System Pharmacists (ASHP) Midyear were extremely important to important for students, while RPDs viewed these experiences as somewhat important at best (p < 0.02). The majority of RPDs (67%) have no APPE schedule preference, while most students (77%) feel that certain APPE schedules may influence acceptance into residency. Based on findings, information outlined can be used to dispel and/or validate common beliefs held by students regarding experiential factors that help or hinder a successful postgraduate year 1 (PGY1) residency match.

Background Adolescents’ health is greatly influenced by social determinants, including gender norms. Although research has shown that there is an association between gender attitudes and adolescents’ sexual behaviour, few studies have assessed this relationship carefully. The Attitudes toward Women Scale for Adolescents (AWSA) is widely used to assess gender attitudes among adolescents; however, to our knowledge it has not been applied in Latin America. Objective To apply AWSA in Latin America for the first time, to perform a factorial validation of this scale and to assess the relationship of gender attitudes and sexual behaviour in Bolivian and Ecuadorian adolescents. Design This cross-sectional study was carried out in 2011 among 14–18 year olds in 20 high schools in Cochabamba (Bolivia) and six in Cuenca (Ecuador) as a part of a larger project. Schools were purposively selected. A Spanish version of the 12-item AWSA was employed for this study. The assessed aspects of adolescent sexual behaviour were: reported sexual intercourse, reported positive experience during last sexual intercourse and reported current use of contraception. The psychometric properties of AWSA were investigated, and both explanatory and confirmatory factorial analyses were performed. Results The number of questionnaires included in the analysis was 3,518 in Bolivia and 2,401 in Ecuador. A factorial analysis of AWSA resulted in three factors: power dimension (PD), equality dimension (ED) and behavioural dimension (BD). ED showed the highest correlates with adolescent sexual behaviour. Higher scores of this dimension were associated with a more positive experience of sexual relationships, a higher current use of modern contraception and greater sexual activity among girls. Conclusions This study revealed a three-factorial structure of AWSA and demonstrated that by employing factors, the sensitivity of AWSA increases as compared to using the scale as a whole to assess sexual behaviour. This could have important implications for future research on gender and the sexual experiences of adolescents. PMID:24461355

The Climate Change Impacts and Responses: Societal Indicators for the National Climate Assessment workshop, sponsored by the National Aeronautics and Space Administration (NASA) for the National Climate Assessment (NCA), was held on April 28-29, 2011 at The Madison Hotel in Washington, DC. A group of 56 experts (see list in Appendix B) convened to share their experiences. Participants brought to bear a wide range of disciplinary expertise in the social and natural sciences, sector experience, and knowledge about developing and implementing indicators for a range of purposes. Participants included representatives from federal and state government, non-governmental organizations, tribes, universities, and communities. The purpose of the workshop was to assist the NCA in developing a strategic framework for climate-related physical, ecological, and socioeconomic indicators that can be easily communicated with the U.S. population and that will support monitoring, assessment, prediction, evaluation, and decision-making. The NCA indicators are envisioned as a relatively small number of policy-relevant integrated indicators designed to provide a consistent, objective, and transparent overview of major variations in climate impacts, vulnerabilities, adaptation, and mitigation activities across sectors, regions, and timeframes. The workshop participants were asked to provide input on a number of topics, including: (1) categories of societal indicators for the NCA; (2) alternative approaches to constructing indicators and the better approaches for NCA to consider; (3) specific requirements and criteria for implementing the indicators; and (4) sources of data for and creators of such indicators. Socioeconomic indicators could include demographic, cultural, behavioral, economic, public health, and policy components relevant to impacts, vulnerabilities, and adaptation to climate change as well as both proactive and reactive responses to climate change. Participants provided inputs through in-depth discussion in breakout sessions, plenary sessions on break-out results, and several panels that provided key insights about indicators, lessons learned through experience with developing and implementing indicators, and thoughts on how the NCA could proceed to develop indicators for the NCA.

Small Gas Bubble Experiment for Mitigation of Cavitation Damage and Pressure Waves in Short-pulse Mercury Spallation Targets

Populations of small helium gas bubbles were introduced into a flowing mercury experiment test loop to evaluate mitigation of beam-pulse induced cavitation damage and pressure waves. The test loop was developed and thoroughly tested at the Spallation Neutron Source (SNS) prior to irradiations at the Los Alamos Neutron Science Center - Weapons Neutron Research Center (LANSCE-WNR) facility. Twelve candidate bubblers were evaluated over a range of mercury flow and gas injection rates by use of a novel optical measurement technique that accurately assessed the generated bubble size distributions. Final selection for irradiation testing included two variations of a swirl bubblermore » provided by Japan Proton Accelerator Research Complex (J-PARC) collaborators and one orifice bubbler developed at SNS. Bubble populations of interest consisted of sizes up to 150 m in radius with achieved gas void fractions in the 10^-5 to 10^-4 range. The nominal WNR beam pulse used for the experiment created energy deposition in the mercury comparable to SNS pulses operating at 2.5 MW. Nineteen test conditions were completed each with 100 pulses, including variations on mercury flow, gas injection and protons per pulse. The principal measure of cavitation damage mitigation was surface damage assessment on test specimens that were manually replaced for each test condition. Damage assessment was done after radiation decay and decontamination by optical and laser profiling microscopy with damaged area fraction and maximum pit depth being the more valued results. Damage was reduced by flow alone; the best mitigation from bubble injection was between half and a quarter that of flow alone. Other data collected included surface motion tracking by three laser Doppler vibrometers (LDV), loop wall dynamic strain, beam diagnostics for charge and beam profile assessment, embedded hydrophones and pressure sensors, and sound measurement by a suite of conventional and contact microphones.« less

Patient engagement is a transformative strategy for improving value assessment. US value framework developers have increased engagement activities, but more needs to be learned about how to best achieve meaningful patient engagement in value assessment. The objective was to glean good practices in patient engagement emerging from patient community experiences, to be used in value assessment. The National Health Council Value Workgroup conducted a survey and held a focus group with its member advocacy organizations to gather experiences with value framework developers and views on emerging good practices. Ten of 13 organizations completed the survey; reporting 13 interactions with four framework developers. Most rated experiences as "good" to "very good." Emerging good practices included (1) engage early; (2) engage a range of patients; (3) leverage patient-provided information, data resources, and outreach mechanisms; (4) be transparent; and (5) appreciate and accommodate resource constraints. Twelve of 13 organizations participated in the focus group, and this produced 30 emerging good practices in four areas: (1) timing; (2) methodology and data; (3) partnering; and (4) characterizing engagement. Patient engagement was limited in early development of value frameworks but has increased in the past few years. Patient groups report positive experiences that can serve as emerging good practices. These groups also reported experienced challenges in their interactions and recommended good practices to mitigate those challenges. The growing pool of patient engagement experiences can be translated into good practices to advance a patient-centered, value-driven health care ecosystem. Lessons learned from these early experiences can help establish recommend emerging good practices that can eventually result in best practices and standards in the field.

Burke, Shanna L; Burgess, Aaron; Cadet, Tamara

2017-01-01

Objective The purpose of this study was to examine the most effective and available English and Spanish language caregiver assessments for providers and caregivers. Methods Assessments were included if they screened for caregiving-related concerns, including stress, depression, and caregiving burden and could be administered directly to caregivers in person or online. Results Eighteen assessments are designed to assess caregiver burden, distress, depression, and grief. Six did not have psychometric data to support efficacy but are widely used in clinical and research settings. Six were validated in Spanish, and one other is available in Spanish but not validated. Conclusion As many as 80% of care recipients are cared for in the home by family members who act as informal caregivers. Caregivers of persons with dementia may experience depression symptoms, high caregiver burden, and feelings of being constrained. Due to the lack of psychometric evidence available, the validity of some assessments is questionable.

Self-evaluation of assessment programs: a cross-case analysis.

2011-08-01

The goal of this article is to contribute to the validation of a self-evaluation method, which can be used by schools to evaluate the quality of their Competence Assessment Program (CAP). The outcomes of the self-evaluations of two schools are systematically compared: a novice school with little experience in competence-based education and assessment, and an innovative school with extensive experience. The self-evaluation was based on 12 quality criteria for CAPs, including both validity and reliability, and criteria stressing the importance of the formative function of assessment, such as meaningfulness and educational consequences. In each school, teachers, management and examination board participated. Results show that the two schools use different approaches to assure assessment quality. The innovative school seems to be more aware of its own strengths and weaknesses, to have a more positive attitude towards teachers, students, and educational innovations, and to explicitly involve stakeholders (i.e., teachers, students, and the work field) in their assessments. This school also had a more explicit vision of the goal of competence-based education and could design its assessments in accordance with these goals. Copyright © 2011 Elsevier Ltd.

2017-05-01

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

Assess 2: Spacelab simulation. Executive summary

NASA Technical Reports Server (NTRS)

1977-01-01

An Airborne Science/Spacelab Experiments System Simulation (ASSESS II) mission, was conducted with the CV-990 airborne laboratory in May 1977. The project studied the full range of Spacelab-type activities including management interactions, experiment selection and funding, hardware development, payload integration and checkout, mission specialist and payload specialist selection and training, mission control center payload operations control center arrangements and interactions, real time interaction during flight between principal investigators and the flight crew, and retrieval of scientific flight data. ESA established an integration and coordination center for the ESA portion of the payload as planned for Spacelab. A strongly realistic Spacelab mission was conducted on the CV-990 aircraft. U.S. and ESA scientific experiments were integrated into a payload and flown over a 10 day period, with the payload flight crew fully-confined to represent a Spacelab mission. Specific conclusions for Spacelab planning are presented along with a brief explanation of each.

In two studies, we explored the frequency and phenomenology of musical imagery. Study 1 used retrospective reports of musical imagery to assess the contribution of individual differences to imagery characteristics. Study 2 used an experience sampling design to assess the phenomenology of musical imagery over the course of one week in a sample of musicians and non-musicians. Both studies found episodes of musical imagery to be common and positive: people rarely wanted such experiences to end and often heard music that was personally meaningful. Several variables predicted musical imagery, including personality, musical preferences, and positive mood. Musicians tended to hear musical imagery more often, but they reported less frequent episodes of deliberately-generated imagery. Taken together, the present research provides new insights into individual differences in musical imagery, and it supports the emerging view that such experiences are common, positive, and more voluntary than previously recognized.

2014-01-01

The purpose of our study was to explore the experiences of marriage and family therapists in working with violent couples. In particular, we focused on therapists’ questions and feelings of competency pertaining to violence assessment and treatment, the difficulties they face during their practices, and the factors that affect their practice. Data for this study was collected via a focus group that lasted approximately an hour. The participants included five marriage and family therapists. A set of questions were used to explore experiences of therapists who were working with clients who are experiencing domestic violence. The research team recorded the answers to these questions as well as associated discussion. A grounded theory approach was used to analyze the data. Six themes were derived from the coded data: acknowledgment and reliance on systemic foundations, therapist factors, assessment, treatment considerations, sex of batterers, and training in Marriage and Family Therapy programs.

Understanding the Impact of Childhood Sexual Abuse on Men’s Risk Behavior: Protocol for a Mixed-Methods Study

PubMed Central

2018-01-01

Background Childhood sexual abuse (CSA) remains a critical public health issue among black and Latino men who have sex with men (MSM), as it is associated with multiple negative outcomes including substance misuse, poor mental health, revictimization, and high-risk sexual behavior. Most CSA research with MSM relies on quantitative assessment that often precludes consideration of cultural variations in how formative sexual experiences are understood and is based on inconsistent or overly restrictive definitions of abuse, and therefore may fail to detect certain abusive experiences (eg, those involving female perpetrators), which can have harmful health consequences if they remain unrecognized. Objective The objective of this study is to overcome existing limitations in the literature by drawing on perspectives of black and Latino MSM and men who have sex with men and women (MSMW), as well as relevant service providers to better understand the role of, and the need to include, sexual abuse histories (eg, CSA) in treatment and counseling settings, with the long-term goal of improving assessment and health outcomes. Methods We will conduct mixed-methods interviews, framed by an intersectionality approach, with 80 black and Latino men (40 MSM and 40 MSMW) in New York City (NYC), exploring appraisals of their formative sexual experiences, including those described as consensual but meeting criteria for CSA. We will also interview 30 local service providers representing substance abuse treatment, mental health care, and HIV prevention and outreach. Results The study was launched in May 2017. Conclusions This formative research will inform testable approaches to assessing and incorporating sexual abuse history into substance abuse treatment and other health and mental health services used by men with such histories.

Despite growing interest in engaging patients and families (P/F) in patient safety education, little is known about how P/F can best contribute. We assessed the feasibility and acceptability of a patient-teacher medical error disclosure and prevention training model. We developed an educational intervention bringing together interprofessional clinicians with P/F from hospital advisory councils to discuss error disclosure and prevention. Patient focus groups and orientation sessions informed curriculum and assessment design. A pre-post survey with qualitative and quantitative questions was used to assess P/F and clinician experiences and attitudes about collaborative safety education including participant hopes, fears, perceived value of learning experience and challenges. Responses to open-ended questions were coded according to principles of content analysis. P/F and clinicians hoped to learn about each other's perspectives, communication skills and patient empowerment strategies. Before the intervention, both groups worried about power dynamics dampening effective interaction. Clinicians worried that P/F would learn about their fallibility, while P/F were concerned about clinicians' jargon and defensive posturing. Following workshops, clinicians valued patients' direct feedback, communication strategies for error disclosure and a 'real' learning experience. P/F appreciated clinicians' accountability, and insights into how medical errors affect clinicians. Half of participants found nothing challenging, the remainder clinicians cited emotions and enormity of 'culture change', while P/F commented on medical jargon and desire for more time. Patients and clinicians found the experience valuable. Recommendations about how to develop a patient-teacher programme in patient safety are provided. An educational paradigm that includes patients as teachers and collaborative learners with clinicians in patient safety is feasible, valued by clinicians and P/F and promising for P/F-centred medical error disclosure and prevention training.

Beard, Steven D.; Reardon, Scott E.; Tobias, Eric L.; Aponso, Bimal L.

2013-01-01

Fidelity is a word that is often used but rarely understood when talking about groundbased simulation. Assessing the cueing fidelity of a ground based flight simulator requires a comparison to actual flight data either directly or indirectly. Two experiments were conducted at the Vertical Motion Simulator using the GenHel UH-60A Black Hawk helicopter math model that was directly compared to flight data. Prior to the experiment the simulator s motion and visual system frequency responses were measured, the aircraft math model was adjusted to account for the simulator motion system delays, and the motion system gains and washouts were tuned for the individual tasks. The tuned motion system fidelity was then assessed against the modified Sinacori criteria. The first experiments showed similar handling qualities ratings (HQRs) to actual flight for a bob-up and sidestep maneuvers. The second experiment showed equivalent HQRs between flight and simulation for the ADS33 slalom maneuver for the two pilot participants. The ADS33 vertical maneuver HQRs were mixed with one pilot rating the flight and simulation the same while the second pilot rated the simulation worse. In addition to recording HQRs on the second experiment, an experimental Simulation Fidelity Rating (SFR) scale developed by the University of Liverpool was tested for applicability to engineering simulators. A discussion of the SFR scale for use on the Vertical Motion Simulator is included in this paper.

Within this paper we present an autonomic Computing resources management system, used by LHCb for assessing the status of their Grid resources. Virtual Organizations Grids include heterogeneous resources. For example, LHC experiments very often use resources not provided by WLCG, and Cloud Computing resources will soon provide a non-negligible fraction of their computing power. The lack of standards and procedures across experiments and sites generated the appearance of multiple information systems, monitoring tools, ticket portals, etc... which nowadays coexist and represent a very precious source of information for running HEP experiments Computing systems as well as sites. These two facts lead to many particular solutions for a general problem: managing the experiment resources. In this paper we present how LHCb, via the DIRAC interware, addressed such issues. With a renewed Central Information Schema hosting all resources metadata and a Status System (Resource Status System) delivering real time information, the system controls the resources topology, independently of the resource types. The Resource Status System applies data mining techniques against all possible information sources available and assesses the status changes, that are then propagated to the topology description. Obviously, giving full control to such an automated system is not risk-free. Therefore, in order to minimise the probability of misbehavior, a battery of tests has been developed in order to certify the correctness of its assessments. We will demonstrate the performance and efficiency of such a system in terms of cost reduction and reliability.

Pandemic risk prevention in European countries: role of the ECDC in preparing for pandemics. Development and experience with a national self-assessment procedure, 2005-2008.

PubMed

Nicoll, A

2010-12-01

To be effective risk prevention work takes place well before pandemics through the three Ps: Planning, Preparedness and Practise. Between 2005 and 2008 the European Centre for Disease Prevention and Control (ECDC) worked with the European Commission (EC) and the WHO Regional Office for Europe (WHO-Euro) to assist European countries in preparing themselves for a future influenza pandemic. All eligible countries in the European Union and European Economic Area participated with energy and commitment. Indicators of preparedness were developed based on WHO planning guidance and these were set within a simple assessment which included a formal country visit. The procedure evolved considerably with field experience. As the complexity of pandemic preparedness was appreciated it changed from being a classical short external assessment to longer national self-assessments with demonstrable impact, especially when self-assessments were published. There were essential supporting activities undertaken including a series of pan-European pandemic preparedness workshops organised by EC, WHO-Euro, ECDC and countries holding the European Union Presidency. The self-assessments highlighted additional work and documentation that was needed by national authorities from the ECDC. This work was undertaken and the document produced. The benefits of the self-assessments were seen in the 2009 pandemic in that EU/EEA countries performed better than some others. A number of the guidance documents were updated to fit the specific features of the pandemic. However the pandemic revealed many weaknesses and brought new challenges for European countries, notably over communication and vaccines, the need to prepare for a variety of scenarios and to factor severity estimates into preparedness, to improve surveillance for severe disease and to deliver seroepidemiology. Any revised self-assessment procedure will need to respond to these challenges.

Therapeutic Assessment of Complex Trauma: A Single-Case Time-Series Study.

Tarocchi, Anna; Aschieri, Filippo; Fantini, Francesca; Smith, Justin D

2013-06-01

The cumulative effect of repeated traumatic experiences in early childhood incrementally increases the risk of adjustment problems later in life. Surviving traumatic environments can lead to the development of an interrelated constellation of emotional and interpersonal symptoms termed complex posttraumatic stress disorder (CPTSD). Effective treatment of trauma begins with a multimethod psychological assessment and requires the use of several evidence-based therapeutic processes, including establishing a safe therapeutic environment, reprocessing the trauma, constructing a new narrative, and managing emotional dysregulation. Therapeutic Assessment (TA) is a semistructured, brief intervention that uses psychological testing to promote positive change. The case study of Kelly, a middle-aged woman with a history of repeated interpersonal trauma, illustrates delivery of the TA model for CPTSD. Results of this single-case time-series experiment indicate statistically significant symptom improvement as a result of participating in TA. We discuss the implications of these findings for assessing and treating trauma-related concerns, such as CPTSD.

Preferences of newborn mice for odours indicating closer genetic relatedness: is experience necessary?

PubMed

Todrank, Josephine; Busquet, Nicolas; Baudoin, Claude; Heth, Giora

2005-10-07

Evidence from studies with adult rodents indicates that individual recognition enables distinctions between familiar individuals irrespective of relatedness (but including close kin) and a separate mechanism enables discriminations based on genetic relatedness without prior familiarity. For example, adult mice could assess the extent of their genetic relatedness to unfamiliar individuals using perceptual similarities between their individual odours. The ontogeny of this genetic relatedness assessment mechanism, however, had not been investigated. Here, in two-choice tests, newborn mice differentially preferred odours of more genetically similar lactating females (paternal aunts to unrelated conspecific and conspecific to heterospecific) even without prior direct exposure to adults with the tested genotypes. The results provide a direct demonstration of genetic relatedness assessment abilities in newborns and show that experience with parental odours is not necessary for genetic relatedness distinctions. Future studies will be necessary to determine whether exposure to odours of other foetuses in the womb or littermates shortly after birth affects this genetic relatedness assessment process.

2009-10-01

The purpose of this study was to describe final year undergraduate nurses' experiences of assessment through the use of a learning contract. Using a qualitative descriptive design, data was collected from a purposive sample of final (fourth) year undergraduate student nurses. Two approaches were taken for data collection, anonymous evaluative questionnaires and interviews. The study was approved by the local university research and ethics committee. Data was thematically analysed. This article presents and discusses the findings from the interviews. Findings suggest that students' approach to the assessment strategy influenced engagement with the learning contract. Three themes were identified: skills, perceptions, and actions. Within these themes three types of learner were identified: happy, pragmatic and fearful. Factors found to influence successful completion of the learning contract were: support, relevant skills, prior experiential learning and required theoretical knowledge. Recommendations include the need for educators to consider module assessments that recognise the learning needs and preferences of the student within a supportive environment.

Conducting mental status examination and suicide risk assessment is an important skill required of nurses when they are in the clinical setting. With nursing students often expressing the anxiety and lack of confidence in doing so, the use of standardized patients provide an excellent opportunity to practice and become proficient with this skill in a simulated environment. To explore the learning experience of undergraduate nursing students using standardized patients while practising their mental status examination and suicide risk assessment skills in mental health nursing module. A pre- and post-test, single group quasi experimental design was used in this study. A standard didactic tutorial session and a standardized patient session was conducted to evaluate the learning experience of undergraduate nursing students learning mental status examination and suicide risk assessment. Outcome measures for this study include Student Satisfaction and Self-Confidence in learning scale. Qualitative comments in the form of open-ended questions were also collected in this study. A University offering nursing program from undergraduate to postgraduate level. A convenience sample of Year 2 undergraduate nursing students undertaking the mental health nursing module was included in this study. The use of standardized patient session had significantly increased students' satisfaction and confidence level before they are posted to a mental health setting for their clinical attachment. There was a significant difference on students' self-confidence level for those who have taken care of a patient with mental illness after adjusting for pre-test on score in learning. Qualitative feedback obtained from students showed a positive outlook towards the use of standardized patient as an effective tool in augmenting didactic learning into practical skills. Using standardized patient in mental health nursing education enhanced the integration of didactic content into clinical setting allowing students to practice their assessment skills learned in classroom and transfer it to the clinical area. The benefits of using standardized patient include allowing students to practice their communication skills and improving their confidence level in conducting mental status examination and suicide risk assessment by reducing anxiety as compared with traditional classroom and textbook-based pedagogy.

Analysis of the correlation between the assessment of current family relations in families of patients diagnosed with eating disorders and the assessment of the relations in the family of origin of their parents. 54 female patients with restrictive anorexia nervosa, 22 female patients with binge-purge anorexia, 36 female patients with bulimia. Two control groups were included: 36 female patients with depressive disorders and 85 schoolgirls from Krakow. The study also covered the girls' parents. Family of Origin Scale and FAM Family Assessment Measure (Polish version). In the families of schoolgirls from Krakow better evaluation of the experience of intimacy and autonomy in the family of origin of parents of the investigated girls was associated with their and their children more favourable perception of relations in the present nuclear family. What proved particularly significant were perception of transgenerational experiences of the fathers. Only a few statistically significant correlations were observed in all clinical groups. In the parents of the investigated patients a weak correlation was observed between the current marital relations perception and transgenerational experiences evaluation and a significant correlation between parents' transgenerational experience evaluation and the assessment of the relations with their daughters. No specific correlations were found between the perception of the transgenerational experience of parents and evaluation of current relations in the nuclear family of their children with eating disorders. The results in the group with eating disorders suggest that the relations between parents and daughters are more intense than marital relations.

Objectives Patient-reported experience measures are increasingly being used to routinely monitor the quality of care. With the increasing attention on such measures, hospital managers seek ways to systematically improve patient experience across hospital departments, in particular where outcomes are used for public reporting or reimbursement. However, it is currently unclear whether hospitals with more mature quality management systems or stronger focus on patient involvement and patient-centered care strategies perform better on patient-reported experience. We assessed the effect of such strategies on a range of patient-reported experience measures. Materials and Methods We employed a cross-sectional, multi-level study design randomly recruiting hospitals from the Czech Republic, France, Germany, Poland, Portugal, Spain, and Turkey between May 2011 and January 2012. Each hospital contributed patient level data for four conditions/pathways: acute myocardial infarction, stroke, hip fracture and deliveries. The outcome variables in this study were a set of patient-reported experience measures including a generic 6-item measure of patient experience (NORPEQ), a 3-item measure of patient-perceived discharge preparation (Health Care Transition Measure) and two single item measures of perceived involvement in care and hospital recommendation. Predictor variables included three hospital management strategies: maturity of the hospital quality management system, patient involvement in quality management functions and patient-centered care strategies. We used directed acyclic graphs to detail and guide the modeling of the complex relationships between predictor variables and outcome variables, and fitted multivariable linear mixed models with random intercept by hospital, and adjusted for fixed effects at the country level, hospital level and patient level. Results Overall, 74 hospitals and 276 hospital departments contributed data on 6,536 patients to this study (acute myocardial infarction n = 1,379, hip fracture n = 1,503, deliveries n = 2,088, stroke n = 1,566). Patients admitted for hip fracture and stroke had the lowest scores across the four patient-reported experience measures throughout. Patients admitted after acute myocardial infarction reported highest scores on patient experience and hospital recommendation; women after delivery reported highest scores for patient involvement and health care transition. We found no substantial associations between hospital-wide quality management strategies, patient involvement in quality management, or patient-centered care strategies with any of the patient-reported experience measures. Conclusion This is the largest study so far to assess the complex relationship between quality management strategies and patient experience with care. Our findings suggest absence of and wide variations in the institutionalization of strategies to engage patients in quality management, or implement strategies to improve patient-centeredness of care. Seemingly counterintuitive inverse associations could be capturing a scenario where hospitals with poorer quality management were beginning to improve their patient experience. The former suggests that patient-centered care is not yet sufficiently integrated in quality management, while the latter warrants a nuanced assessment of the motivation and impact of involving patients in the design and assessment of services.

Patient-reported experience measures are increasingly being used to routinely monitor the quality of care. With the increasing attention on such measures, hospital managers seek ways to systematically improve patient experience across hospital departments, in particular where outcomes are used for public reporting or reimbursement. However, it is currently unclear whether hospitals with more mature quality management systems or stronger focus on patient involvement and patient-centered care strategies perform better on patient-reported experience. We assessed the effect of such strategies on a range of patient-reported experience measures. We employed a cross-sectional, multi-level study design randomly recruiting hospitals from the Czech Republic, France, Germany, Poland, Portugal, Spain, and Turkey between May 2011 and January 2012.

2018-07-15

A Health Impact Assessment (HIA) is an evidence-based methodology that includes health promotion and protection goals in decision-making. HIA has been introduced and/or institutionalized to various extents in different countries. In order to promote HIA and preventive health assessments in Italy, a research methodology was followed to identify specific obstacles or facilitators. The experiences of various countries reported in the literature were analyzed in terms of facilitating or hindering the introduction and institutionalization of HIA. A consultation with the proponents of projects and plans in Italy was carried out with a multi-approach methodology in order to characterize the national context. A general implementation plan was drawn up from the international experiences. In Italy this is not yet in place. Specific areas of intervention need to be addressed, including: 1) data availability; 2) tools and methods; 3) engagement of stakeholders; 4) capacity building. The research suggests that the institutionalization of HIA in Italy rests on the government's commitment to providing specific legislation regarding HIA so that skills, intersectoral coordination and dedicated budgets can be built and maintained.

Yi, Steven; Lu, Minta; Yee, Adam; Harmon, John; Meng, Frank; Hinduja, Saurabh

2018-03-01

In this paper, we present a thermal imaging based app to augment traditional appearance based wound growth monitoring. Accurate diagnose and track of wound healing enables physicians to effectively assess, document, and individualize the treatment plan given to each wound patient. Currently, wounds are primarily examined by physicians through visual appearance and wound area. However, visual information alone cannot present a complete picture on a wound's condition. In this paper, we use a smartphone attached thermal imager and evaluate its effectiveness on augmenting visual appearance based wound diagnosis. Instead of only monitoring wound temperature changes on a wound, our app presents physicians a comprehensive measurements including relative temperature, wound healing thermal index, and wound blood flow. Through the rat wound experiments and by monitoring the integrated thermal measurements over 3 weeks of time frame, our app is able to show the underlying healing process through the blood flow. The implied significance of our app design and experiment includes: (a) It is possible to use a low cost smartphone attached thermal imager for added value on wound assessment, tracking, and treatment; and (b) Thermal mobile app can be used for remote wound healing assessment for mobile health based solution.

Blending technology in teaching advanced health assessment in a family nurse practitioner program: using personal digital assistants in a simulation laboratory.

Elliott, Lydia; DeCristofaro, Claire; Carpenter, Alesia

2012-09-01

This article describes the development and implementation of integrated use of personal handheld devices (personal digital assistants, PDAs) and high-fidelity simulation in an advanced health assessment course in a graduate family nurse practitioner (NP) program. A teaching tool was developed that can be utilized as a template for clinical case scenarios blending these separate technologies. Review of the evidence-based literature, including peer-reviewed articles and reviews. Blending the technologies of high-fidelity simulation and handheld devices (PDAs) provided a positive learning experience for graduate NP students in a teaching laboratory setting. Combining both technologies in clinical case scenarios offered a more real-world learning experience, with a focus on point-of-care service and integration of interview and physical assessment skills with existing standards of care and external clinical resources. Faculty modeling and advance training with PDA technology was crucial to success. Faculty developed a general template tool and systems-based clinical scenarios integrating PDA and high-fidelity simulation. Faculty observations, the general template tool, and one scenario example are included in this article. ©2012 The Author(s) Journal compilation ©2012 American Academy of Nurse Practitioners.

1992-01-01

The Solar Array Module Plasma Interaction Experiment (SAMPIE) has two key instruments at the heart of its data acquisition capability. One of these, the electrometer, is designed to measure both ion and electron current from most of the samples included in the experiment. The accuracy requirement, specified by the project's Principal Investigator, is for agreement within 10 percent with a calibrated laboratory instrument. Plasma chamber testing was performed to assess the capabilities of the prototype design. Agreement was determined to be within 2 percent for electron collection and within 3 percent for ion collection.

Inclusion of policies on ethical standards in animal experiments in biomedical science journals.

PubMed

Rands, Sean A

2011-11-01

Most published biomedical research involving animal models is evaluated carefully to ensure that appropriate ethical standards are met. In the current study, 500 journals randomly selected from MedLine were assessed for whether they presented animal research. Of the 138 journals that did, the instructions to authors of 85 (61.6%) included a requirement for author assurance of adherence to ethical standards during experiments involving animals. In comparison to a wider range of biologic journals, biomedical science journals were more likely to have some sort of ethical policy concerning the reporting and presentation of animal experiments.

Resident continuity of care experience in a Canadian general surgery training program

PubMed Central

Sidhu, Ravindar S.; Walker, G. Ross

Objectives To provide baseline data on resident continuity of care experience, to describe the effect of ambulatory centre surgery on continuity of care, to analyse continuity of care by level of resident training and to assess a resident-run preadmission clinic’s effect on continuity of care. Design Data were prospectively collected for 4 weeks. All patients who underwent a general surgical procedure were included if a resident was present at operation. Setting The Division of General Surgery, Queen’s University, Kingston, Ont. Outcome measures Preoperative, operative and inhospital postoperative involvement of each resident with each case was recorded. Results Residents assessed preoperatively (before entering the operating room) 52% of patients overall, 20% of patients at the ambulatory centre and 83% of patients who required emergency surgery. Of patients assessed by the chief resident, 94% were assessed preoperatively compared with 32% of patients assessed by other residents ( p < 0.001). Of the admitted patients, 40% had complete resident continuity of care (preoperative, operative and postoperative). There was no statistical difference between this rate and that for emergency, chief-resident and non-chief-resident subgroups. Of the eligible patients, 58% were seen preoperatively by the resident on the preadmission clinic service compared with 54% on other services ( p > 0.1). Conclusions This study serves as a reference for the continuity of care experience in Canadian surgical programs. Residents assessed only 52% of patients preoperatively, and only 40% of patients had complete continuity of care. Factors such as ambulatory surgery and junior level of training negatively affected continuity experience. Such factors must be taken into account in planning surgical education. PMID:10526519

To survey the opinion about various curricular components of Doctor of Medicine (MD) pharmacology curriculum in India by stakeholders, including faculty and students. An online survey was done to evaluate the various curricular components of MD pharmacology curriculum being used in India. A total of 393 respondents including faculty, MD students, and other stakeholders completed the survey. The survey was developed using SurveyMonkey platform and link to survey was E-mailed to stakeholders. The results were expressed as percentages. There was a balanced representation of respondents from various designations, teaching experience, regions, and age groups. Most of the respondents (83%) were aware of the MD pharmacology curriculum. However, they reported that it is more inclined to knowledge domain. About half of respondents (53%) said that animal experiments are being used. The most common teaching methods mentioned are seminars (98.5%), journal clubs (95%), and practical exercises by postgraduates (73%), but there is less use of newer methods (25%) in theory and less of clinical pharmacology exercise (39%) in practical classes. The log books are maintained but not assessed regularly. Internal assessment is sparingly used. The MD pharmacology curriculum needs to be made uniform at the national level and updated to include the newer methods in teaching-learning and assessment. There should be sharing of newer methods at a common platform implemented at the national level.

2016-01-01

Although public health degree programs typically require practica and other field experiences, service-learning courses, with a focus on civic engagement and the application of classroom learning in real world settings, can go beyond these requirements and provide benefits to students and community-based practice partners. The goal of this paper is to assess potential benefits of service-learning programs for both graduate-level public health students and state and local public health agency partners. EpiAssist is a new service-learning program developed at the School of Public Health of the Texas A and M University Health Science Center, USA, in January 2015. EpiAssist was integrated into a new course, Methods in Field Epidemiology. The integration of service-learning was guided by a partnership with the Texas A and M Center for Teaching Excellence. State, regional, and local public health partners requested EpiAssist via email or telephone. A listserv was used to recruit student volunteers to meet requests. 54 of 86 registered EpiAssist students (63%) participated in at least one of ten service-learning and three training activities between January and June, 2015. Service-learning activities included questionnaire development, in-person and telephone data collection, and data analysis. Training topics for students included the Epi Info™ software, community assessment and communicable disease reporting. Students and partner organizations provided generally positive assessments of this service learning program through an online evaluation. Service-learning provides students with enhanced classroom learning through applied public health experience in state, regional and local health departments. These experiences provide both needed surge capacity to public health departments and valuable hands-on field experience to students.

Space Shuttle Projects

In this photograph, astronaut Carl Walz performs the Performance Assessment Workstation (PAWS) experiment at the flight deck of the Space Shuttle Orbiter Columbia during the STS-65 mission. Present day astronauts are subject to a variety of stresses during spaceflight. These include microgravity, physical isolation, confinement, lack of privacy, fatigue, and changing work/rest cycles. The purpose of this experiment is to determine the effects of microgravity upon thinking skills critical to the success of operational tasks in space. The principle objective is to distinguish between the effects of microgravity on specific information-processing skills affecting performance and those of fatigue caused by long work periods. To measure these skills, the investigators use a set of computerized performance tests called the Performance Assessment Workstation, which is based on current theoretical models of human performance. The tests were selected by analyzing tasks related to space missions and their hypothesized sensitivity to microgravity. Multiple subjective measures of cumulative fatigue and changing mood states are also included for interpreting performance data.

2014-11-02

This paper describes the process, our experience and the lessons learnt in doing document reviews of health science curricula. Since we could not find relevant literature to guide us on how to approach these reviews, we feel that sharing our experience would benefit researchers embarking on similar projects. We followed a rigorous, transparent, pre-specified approach that included the preparation of a protocol, a pre-piloted data extraction form and coding schedule. Data were extracted, analysed and synthesised. Quality checks were included at all stages of the process. The main lessons we learnt related to time and project management, continuous quality assurance, selecting the software that meets the needs of the project, involving experts as needed and disseminating the findings to relevant stakeholders. A complete curriculum evaluation comprises, apart from a document review, interviews with students and lecturers to assess the learnt and taught curricula respectively. Rigorous methods must be used to ensure an objective assessment.

The goal of this statement is to review available literature and to put forth a scientific statement on the current practice of fetal cardiac medicine, including the diagnosis and management of fetal cardiovascular disease. A writing group appointed by the American Heart Association reviewed the available literature pertaining to topics relevant to fetal cardiac medicine, including the diagnosis of congenital heart disease and arrhythmias, assessment of cardiac function and the cardiovascular system, and available treatment options. The American College of Cardiology/American Heart Association classification of recommendations and level of evidence for practice guidelines were applied to the current practice of fetal cardiac medicine. Recommendations relating to the specifics of fetal diagnosis, including the timing of referral for study, indications for referral, and experience suggested for performance and interpretation of studies, are presented. The components of a fetal echocardiogram are described in detail, including descriptions of the assessment of cardiac anatomy, cardiac function, and rhythm. Complementary modalities for fetal cardiac assessment are reviewed, including the use of advanced ultrasound techniques, fetal magnetic resonance imaging, and fetal magnetocardiography and electrocardiography for rhythm assessment. Models for parental counseling and a discussion of parental stress and depression assessments are reviewed. Available fetal therapies, including medical management for arrhythmias or heart failure and closed or open intervention for diseases affecting the cardiovascular system such as twin-twin transfusion syndrome, lung masses, and vascular tumors, are highlighted. Catheter-based intervention strategies to prevent the progression of disease in utero are also discussed. Recommendations for delivery planning strategies for fetuses with congenital heart disease including models based on classification of disease severity and delivery room treatment will be highlighted. Outcome assessment is reviewed to show the benefit of prenatal diagnosis and management as they affect outcome for babies with congenital heart disease. Fetal cardiac medicine has evolved considerably over the past 2 decades, predominantly in response to advances in imaging technology and innovations in therapies. The diagnosis of cardiac disease in the fetus is mostly made with ultrasound; however, new technologies, including 3- and 4-dimensional echocardiography, magnetic resonance imaging, and fetal electrocardiography and magnetocardiography, are available. Medical and interventional treatments for select diseases and strategies for delivery room care enable stabilization of high-risk fetuses and contribute to improved outcomes. This statement highlights what is currently known and recommended on the basis of evidence and experience in the rapidly advancing and highly specialized field of fetal cardiac care. © 2014 American Heart Association, Inc.

Cross-cultural psychiatric residency training: the Oregon experience.

PubMed

Boehnlein, James K; Leung, Paul K; Kinzie, John David

2008-01-01

The purpose of this article is to describe the goals and structure of cross-cultural psychiatric training at Oregon Health and Science University (OHSU). This training in core knowledge, skills, and attitudes of cultural psychiatry over the past three decades has included medical students, residents, and fellows, along with allied mental health personnel. The curriculum includes both didactic sessions devoted to core topics in the field and varied clinical experiences in community settings and the Intercultural Psychiatric Program under the supervision of experienced academic faculty. The authors review the central elements of the training experiences and include a detailed description of the core clinical settings and experiences. At the conclusion of their clinical experiences, trainees have specialized cross-cultural psychiatric knowledge and skills, including treatment of refugees and immigrants, sociocultural variables that influence the assessment and treatment of a wide range of psychiatric conditions, and comfort with cultural dynamics that influence both the doctor/patient relationship and collaboration with a wide range of mental health professionals. Because of rapid demographic changes in the U.S. population, providing cross-cultural training for students, residents, and fellows is an essential foundation for the education of the next generation of clinicians and health care leaders. OHSU has provided a long-term model for this training in a busy clinical and academic setting that places an emphasis on multidisciplinary and multicultural collaboration.

Performance-based comparison of neonatal intubation training outcomes: simulator and live animal.

2015-02-01

The purpose of this article was to establish psychometric validity evidence for competency assessment instruments and to evaluate the impact of 2 forms of training on the abilities of clinicians to perform neonatal intubation. To inform the development of assessment instruments, we conducted comprehensive task analyses including each performance domain associated with neonatal intubation. Expert review confirmed content validity. Construct validity was established using the instruments to differentiate between the intubation performance abilities of practitioners (N = 294) with variable experience (novice through expert). Training outcomes were evaluated using a quasi-experimental design to evaluate performance differences between 294 subjects randomly assigned to 1 of 2 training groups. The training intervention followed American Heart Association Pediatric Advanced Life Support and Neonatal Resuscitation Program protocols with hands-on practice using either (1) live feline or (2) simulated feline models. Performance assessment data were captured before and directly following the training. All data were analyzed using analysis of variance with repeated measures and statistical significance set at P < .05. Content validity, reliability, and consistency evidence were established for each assessment instrument. Construct validity for each assessment instrument was supported by significantly higher scores for subjects with greater levels of experience, as compared with those with less experience (P = .000). Overall, subjects performed significantly better in each assessment domain, following the training intervention (P = .000). After controlling for experience level, there were no significant differences among the cognitive, performance, and self-efficacy outcomes between clinicians trained with live animal model or simulator model. Analysis of retention scores showed that simulator trained subjects had significantly higher performance scores after 18 weeks (P = .01) and 52 weeks (P = .001) and cognitive scores after 52 weeks (P = .001). The results of this study demonstrate the feasibility of using valid, reliable assessment instruments to assess clinician competency and self-efficacy in the performance of neonatal intubation. We demonstrated the relative equivalency of live animal and simulation-based models as tools to support acquisition of neonatal intubation skills. Retention of performance abilities was greater for subjects trained using the simulator, likely because it afforded greater opportunity for repeated practice. Outcomes in each assessment area were influenced by the previous intubation experience of participants. This suggests that neonatal intubation training programs could be tailored to the level of provider experience to make efficient use of time and educational resources. Future research focusing on the uses of assessment in the applied clinical environment, as well as identification of optimal training cycles for performance retention, is merited.

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

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

Chinese medicine (CM) is major form of traditional and complementary medicine used by Chinese populations. Evaluation on patients' experience on CM service is essential for improving service quality. This cross sectional study aims (i) to assess how CM clinics with different administrative model differ in terms of quality from patients' perspective; and (ii) to investigate how quality varies with patients' demographic and health characteristics. Five hundred and sixteen patients were sampled from charity and semi-public CM clinics in Hong Kong, and were invited to assess their experience using the Primary Care Assessment Tool (PCAT). Results indicated that overall mean PCAT scoring is satisfactory, achieving 70.7% (91.26/129) of total score. Ratings were lower in areas of "coordination of patient information", "continuity of care", and "range of service provided". Impact of administrative models, including involvement of tax-funded healthcare system and outreach delivery, were minimal after adjusting for patient characteristics. Demographic and health characteristics of patients did not contribute to substantial variations in scoring. To improve patient experience, policy makers should consider strengthening care coordination, continuity and comprehensiveness in CM primary care services. Sharing of electronic records and establishing referral system are potential solutions for linking CM and conventional healthcare services.

During the last decade, teamwork has been addressed under the rationale of interprofessional practice or collaboration, highlighted by the attributes of this practice such as: interdependence of professional actions, focus on user needs, negotiation between professionals, shared decision making, mutual respect and trust among professionals, and acknowledgment of the role and work of the different professional groups. Teamwork and interprofessional collaboration have been pointed out as astrategy for effective organization of health care services as the complexity of healthcare requires integration of knowledge and practices from differente professional groups. This integration has a qualitative dimension that can be identified through the experiences of health professionals and to the meaning they give to teamwork. The objective of this systematic review was to synthesize the best available evidence on the experiences of health professionals regarding teamwork and interprofessional collaboration in primary health care settings. The populations included were all officially regulated health professionals that work in primary health settings: dentistry, medicine, midwifery, nursing, nutrition, occupational therapy, pharmacy, physical education, physiotherapy, psychology, social work and speech therapy. In addition to these professionals, community health workers, nursing assistants, licensed practical nurses and other allied health workers were also included. The phenomena of interest were experiences of health professionals regarding teamwork and interprofessional collaboration in primary health care settings. The context was primary health care settings that included health care centers, health maintenance organizations, integrative medicine practices, integrative health care, family practices, primary care organizations and family medical clinics. National health surgery as a setting was excluded. The qualitative component of the review considered studies that focused on qualitative data including designs such as phenomenology, grounded theory, ethnography, action research and feminist research. A three-step search strategy was utilized. Ten databases were searched for papers published from 1980 to June 2015. Studies published in English, Portuguese and Spanish were considered. Methodological quality was assessed using the Qualitative Assessment and Review Instrument developed by the Joanna Briggs Institute. All included studies received a score of at least 70% the questions in the instrument, 11 studies did not address the influence of the researcher on the research or vice-versa, and six studies did not present a statement locating the researcher culturally or theoretically. Qualitative findings were extracted using the Joanna Briggs Institute Qualitative Assessment and Review Instrument. Qualitative research findings were pooled using a pragmatic meta-aggregative approach and the Joanna Briggs Institute Qualitative Assessment and Review Instrument software. This review included 21 research studies, representing various countries and healthcare settings. There were 223 findings, which were aggregated into 15 categories, and three synthesized findings: CONCLUSIONS: This review shows that health professionals experience teamwork and interprofessional collaboration as a process in primary health care settings; its conditions, consequences (benefits and barriers), and finally shows its determinants. Health providers face enormous ideological, organizational, structural and relational challenges while promoting teamwork and interprofessional collaboration in primary health care settings. This review has identified possible actions that could improve implementation of teamwork and interprofessional collaboration in primary health care.

National guidelines in the United Kingdom recommend training Clinical Nurse Specialists in psychological skills to improve the assessment and intervention with psychological problems experienced by people with a cancer diagnosis (National Institute for Health and Clinical Excellence, 2004). This pilot study evaluated a three-day training program combined with supervision sessions from Clinical Psychologists that focused on developing skills in psychological assessment and intervention for common problems experienced by people with cancer. Questionnaires were developed to measure participants' levels of confidence in 15 competencies of psychological skills. Participants completed these prior to the program and on completion of the program. Summative evaluation was undertaken and results were compared. In addition, a focus group interview provided qualitative data of participants' experiences of the structure, process, and outcomes of the program. Following the program, participants rated their confidence in psychological assessment and skills associated with providing psychological support as having increased in all areas. This included improved knowledge of psychological theories, skills in assessment and intervention and accessing and using supervision appropriately. The largest increase was in providing psycho-education to support the coping strategies of patients and carers. Thematic analysis of interview data identified two main themes including learning experiences and program enhancements. The significance of the clinical supervision sessions as key learning opportunities, achieved through the development of a community of practice, emerged. Although this pilot study has limitations, the results suggest that a combined teaching and supervision program is effective in improving Clinical Nurse Specialists' confidence level in specific psychological skills. Participants' experiences highlighted suggestions for refinement and development of the program. Opportunities for further research and developments in this area are discussed.

Psychotic-like experiences (PLEs) have been associated with a variety of adverse outcomes but how they affect happiness in individuals with PLE is unknown. Thus, the aim of the study was to assess the association between PLEs and happiness, and the factors that may influence this association. Nationally representative data from the 2007 Adult Psychiatric Morbidity Survey including adults aged ≥ 16 years was analyzed. The Psychosis Screening Questionnaire was used to assess past 12-month PLE. Individuals who endorsed at least one of the following were considered to have any PLE: thought control, paranoia, strange experiences, auditory hallucinations. Happiness (3-point scale) was assessed with a validated question with higher scores indicating lower levels of happiness. The association between PLE and happiness was assessed by multivariable ordinal logistic regression. Mediation analysis was also performed. Among the 7363 individuals included in the analysis, the prevalence of any PLE increased with decreasing levels of happiness [very happy (2.3%), fairly happy (5.4%), not too happy (14.9%)]. This was also shown in the multivariable analysis adjusted for sociodemographic factors and stressful life events (from very happy to not too happy: OR = 2.41; 95%CI = 1.86-3.12). Mediation analysis showed that anxiety disorders explained the largest proportion of the association (38.8%) followed by depressive episode (28.5%), insomnia (21.9%), disability (16.5%), pain (12.5%), social support (10.0%), and physical health conditions (6.0%). The cross-sectional design limits causal inference. Interventions to identify and address conditions that may have a negative impact on happiness in individuals with PLE may be important to improve their well-being. Copyright © 2017 Elsevier B.V.

We are reporting summary of preliminary safety assessment for Multi Purpose Small Payload Rack(MSPR), which is one of the micro gravity experiment facilities that are being developed for the 2nd phase JEM utilization(JEM: Japanese Experiment Module) that will be launched on H-II Transfer Vehicle(HTV) 2nd flight in 2011. MSPR is used for multi-purpose micro-g experiment providing experimental spaces and work stations. MSPR has three experimental spaces; first, there is a space called Work Volume(WV) with capacity volume of approximately 350 litters, in which multiple resources including electricity, communication, and moving image functions can be used. Within this space, installation of devices can be done by simple, prompt attachment by Velcro and pins with high degree of flexibility. Second, there is Small Experiment Area(SEA), with capacity volume of approximately 70 litters, in which electricity, communication, and moving image functions can also be used in the same way as WV. These spaces protect experiment devices and specimens from contingent loads by the crewmembers. Third, there is Work Bench with area of 0.5 square meters, on which can be used for maintenance, inspection and data operations of installed devices, etc. This bench can be stored in the rack during contingency. Chamber for Combustion Experiment(CCE) that is planned to be installed in WV is a pressure-resistant experimental container that can be used to seal hazardous materials from combustion experiments. This CCE has double sealing design in chamber itself, which resist gas leakage under normal the temperature and pressure. Electricity, communication, moving image function can be used in the same way as WV. JAXA Phase 2 Safety Review Panel(SRP) has been held in April, 2010. For safety analysis of MSPR, hazards were identified based on Fault Tree Analysis methodology and then these hazards were classified into either eight ISS standard-type hazards or eight unique-type hazards that requires special controls based on ISS common safety assessment methodology. Safety evaluation results are reported in the Safety Assessment Report(SAR) 1). Regarding structural failure, unique hazards are especially evaluated considering not only the tolerance for launch load but also load by crewmembers or orbital loads. Regarding electrical shock, electricity design up to secondary power is evaluated in unique hazard from a view point of Electrical design suitable for high voltage(32VDC or more) circuit. Regarding rupture/leakage of pressure system, hazards of fuel supply line, waste line for combustion gas, and pressure system including CCE are evaluated. Also evaluation for contamination due to hazardous gas leakage from CCE is conducted. External propagation of fire from CCE is also evaluated. In this report, we will show the overview of the result of safety assessment and future plan toward critical design phase activity.

The focus of this work is the development of a statistical model for a bioinformatics database whose distinctive structure makes model assessment an interesting and challenging problem. The key components of the statistical methodology, including a fast approximation to the singular value decomposition and the use of adaptive spline modeling and tree-based methods, are described, and preliminary results are presented. These results are shown to compare favorably to selected results achieved using comparitive methods. An attempt to determine the predictive ability of the model through the use of cross-validation experiments is discussed. In conclusion a synopsis of the results of these experiments and their implications for the analysis of bioinformatic databases in general is presented.

Stratospheric Controlled Perturbation Experiment (SCoPEx), is a scientific experiment to advance understanding of stratospheric aerosols. It aims to make quantitative measurements of aerosol microphysics and atmospheric chemistry to improve large-scale models used to assess the risks and benefits of solar geoengineering. A perturbative experiment requires: (a) means to create a well-mixed, small perturbed volume, and (b) observation of time evolution of chemistry and aerosols in the volume. SCoPEx will used a propelled balloon gondola containing all instruments and drive system. The propeller wake forms a well-mixed volume (roughly 1 km long and 100 meters in diameter) that serves as an experimental `beaker' into which aerosols (e.g., < 1 kg of 0.3 µm radius CaCO3 particles) at can be injected; while, the propellers allow the gondola to move at speeds up to 3 m/sec relative to the local air mass driving the gondola back forth through the volume to measure properties of the perturbed air mass. This presentation will provide an overview of the experiment including (a) a systems engineering perspective from high-level scientific questions through instrument selection, mission design, and proposed operations and data analysis; (b) instruments, include current status of integration testing; (c) payload engineering including structure, power and mass budget, etc; (d) results from CFD simulation of propeller wake and simulation of chemistry and aerosol microphysics; and finally (e) proposed concept of operations and schedule. We will also provide an overview of the plans for governance including management of health safety and environmental risks, transparency, public engagement, and larger questions about governance of solar geoengineering experiments. Finally, we will briefly present results of laboratory experiments of the interaction of chemical such as ClONO2 and HCl on particle surfaces relevant for stratospheric solar geoengineering.

FRAMEWORK FOR ASSESSING RISKS OF ...

EPA Pesticide Factsheets

The Framework for Children's Health Risk Assessment report can serve as a resource on children's health risk assessment and it addresses the need to provide a comprehensive and consistent framework for considering children in risk assessments at EPA. This framework lays out the process, points to existing published sources for more detailed information on life stage-specific considerations, and includes web links to specific online publications and relevant Agency science policy papers, guidelines and guidance. The document emphasizes the need to take into account the potential exposures to environmental agents during preconception and all stages of development and focuses on the relevant adverse health outcomes that may occur as a result of such exposures. This framework is not an Agency guideline, but rather describes the overall structure and the components considered important for children's health risk assessment. The document describes an approach that includes problem formulation, analysis, and risk characterization, and also builds on Agency experience assessing risk to susceptible populations. The problem formulation step focuses on the life stage-specific nature of the analysis to include scoping and screening level questions for hazard characterization, dose response and exposure assessment. The risk characterization step recognizes the need to consider life stage-specific risks and explicitly describes the uncertainties and variability in the d

Variability in individual assessment behaviour and its implications for collective decision-making.

Self-organized systems of collective behaviour have been demonstrated in a number of group-living organisms. There is, however, less research relating to how variation in individual assessments may facilitate group decision-making. Here, we investigate this using the decentralized system of collective nest choice behaviour employed by the ant Temnothorax albipennis, combining experimental results with computational modelling. In experiments, isolated workers of this species were allowed to investigate new nest sites of differing quality, and it was found that for any given nest quality, there was wide variation among individuals in the durations that they spent within each nest site. Additionally, individual workers were consistent in spending more time in nest sites of higher quality, and less time in those of lower quality. Hence, the time spent in a new nest site must have included an assessment of nest quality. As nest site visit durations (henceforth termed assessment durations) are linked to recruitment, it is possible that the variability we observed may influence the collective decision-making process of colonies. Thus, we explored this further using a computational model of nest site selection, and found that heterogeneous nest assessments conferred a number of potential benefits. Furthermore, our experiments showed that nest quality assessments were flexible, being influenced by experience of prior options. Our findings help to elucidate the potential mechanisms underlying group behaviour, and highlight the importance of heterogeneity among individuals, rather than precise calibration, in shaping collective decision-making. © 2017 The Author(s).

In selecting a dietary assessment method, several aspects such as the aim of the study and the characteristics of the target population should be taken into account. In elderly people, diminished functionality and cognitive decline may hamper dietary assessment and require tailored approaches to assess dietary intake. The objective of this paper is to summarize our experience in dietary assessment in a number of different studies in population groups over 65 years of age in the Netherlands, and to discuss this experience in the perspective of other nutrition surveys in the elderly. In longitudinal studies, we applied a modified dietary history; in clinical nursing home studies, trained staff observed and recorded food consumption; and in a controlled trial in healthy elderly men, we used a food frequency questionnaire (FFQ). For all methods applied in the community-dwelling elderly people, validation studies showed a similar underestimation of intake of 10-15% compared with the reference value. In the care-depending elderly, the underestimation was less: 5% according to an observational method. The methods varied widely in the resources required, including burden to the participants, field staff and finances. For effective dietary assessment in older adults, the major challenge will be to distinguish between those elderly who are able to respond correctly to the less intensive methods, such as 24-h recalls or FFQ, and those who are not able to respond to these methods and require adapted techniques, for example, observational records.

A significant effort was made to assess the metabolic expenditure for extravehicular activity on the lunar surface. After evaluation of the real-time data available to the flight controller during extravehicular activity, three independent methods of metabolic assessment were chosen based on the relationship between heart rate and metabolic production, between oxygen consumption and metabolic production, and between the thermodynamics of the liquid-cooled garment and metabolic production. The metabolic assessment procedure is analyzed and discussed. Real-time use of this information by the Apollo flight surgeon is discussed. Results and analyses of the Apollo missions and comments concerning future applications are included.

The understandings and meanings eight seventh and eighth grade Latinas gave to science

NASA Astrophysics Data System (ADS)

Parker, Carolyn Ann

My study examined the experiences of eight seventh and eighth grade girls of Central American descent, in and out of the science classroom. The study was interpretive in design and explored the question, "How did the eight participants understand and make meaning of science?" Guided by a sociocultural perspective and a socially critical stance, I explored issues of educational access, particularly to science, mediated by the relationships and experiences formed by families, peers, science classrooms, schools, and society. Data sources included monthly individual interviews, regular focus group meetings, school observations, and interviews with teachers and family members. Findings include the importance of school science experiences that emphasize hands-on activities and the study of topics relevant to students' everyday lives. School influences that I discuss include English-as-a-Second Language learning, English language ability and its effect on classroom interactions, ability grouping, standardized testing, and teachers' instructional practices. Out-of-school influences I examine include the national science education reform movement, familial expectations, and society and the media's portrayal of science and the scientist. The implications and recommendations of the study are particularly germane to practice. Recommendations for the science classroom include a continued emphasis on hands-on science experiences that incorporate high academic expectations for all students, including second-language learners. Moreover, curriculum should be connected and relevant to students' everyday experiences. Recommendations for outside-the-science classroom include a thoughtful examination of the educational environment created by a school's tracking policy and continued support of meaningful professional development experiences for teachers. Future research and the subsequent development of theory should include a further analysis of the influence of gender, ethnicity, science, and recently immigrated students. A study of the influence of English-language ability on students' educational experiences would be especially informative. Studies like this can assist the science education community to implement gender and culturally-equitable curricula, instructional materials, and assessment strategies that could better meet the needs of students who have historically been underrepresented in the discipline, including, but not limited to, second-language learners and recent immigrants to the United States.

Patient experience, 1 of 3 aims for improving health care, is rarely included in studies of patient-centered medical home (PCMH) transformation. This study examines the association between patient experience and National Committee on Quality Assurance (NCQA) PCMH transformation. This was a cross-sectional study of parent-reported child patient experience from PCMH and non-PCMH practices. It used randomly sampled experience surveys completed by 2599 patients at 29 pediatric and family medicine PCMH (n = 21) and non-PCMH (n = 8) practices in Vermont from 2011 to 2013. Patient experiences related to child development and prevention were assessed using the Consumer Assessment of Health care Providers and Systems (CAHPS). A 10-point increase in NCQA score at PCMH practices is associated with a 3.1% higher CAHPS child prevention score (P = .004). Among pediatric practices, PCMH recognition is associated with 7.7% (P < .0005) and 7.2% (P < .0005) higher CAHPS child development and prevention composite scores, respectively. Among family medicine practices, PCMH recognition is associated with 7.4% (P = .001) and 11.0% (P < .0005) lower CAHPS child development and prevention composite scores, respectively. Our results suggest that PCMH recognition may improve child patient experience at pediatric practices and worsen experience at family medicine practices. These findings warrant further investigation into the differential influence of NCQA PCMH transformation on family medicine and pediatric practices. © Copyright 2016 by the American Board of Family Medicine.

Nutritional Biochemistry of Space Flight

Adequate nutrition is critical for maintenance of crew health during and after extended-duration space flight. The impact of weightlessness on human physiology is profound, with effects on many systems related to nutrition, including bone, muscle, hematology, fluid and electrolyte regulation. Additionally, we have much to learn regarding the impact of weightlessness on absorption, mtabolism , and excretion of nutrients, and this will ultimately determine the nutrient requirements for extended-duration space flight. Existing nutritional requirements for extended-duration space flight have been formulated based on limited flight research, and extrapolation from ground-based research. NASA's Nutritional Biochemistry Laboratory is charged with defining the nutritional requirements for space flight. This is accomplished through both operational and research projects. A nutritional status assessment program is included operationally for all International Space Station astronauts. This medical requirement includes biochemical and dietary assessments, and is completed before, during, and after the missions. This program will provide information about crew health and nutritional status, and will also provide assessments of countermeasure efficacy. Ongoing research projects include studies of calcium and bone metabolism, and iron absorption and metabolism. The calcium studies include measurements of endocrine regulation of calcium homeostasis, biochemical marker of bone metabolism, and tracer kinetic studies of calcium movement in the body. These calcium kinetic studies allow for estimation of intestinal absorption, urinary excretion, and perhaps most importantly - deposition and resorption of calcium from bone. The Calcium Kinetics experiment is currently being prepared for flight on the Space Shuttle in 2001, and potentially for subsequent Shuttle and International Space Station missions. The iron study is intended to assess whether iron absorption is down-regulated dUl1ng space flight. This is critical due to the red blood cell changes which occur, and the increase in iron storage that has been observed after space flight. The Iron Absorption and Metabolism experiment is currently planned for long-term flights on the International Space Station.

Bethell, Christina D; Newacheck, Paul; Hawes, Eva; Halfon, Neal

2014-12-01

The ongoing longitudinal Adverse Childhood Experiences Study of adults has found significant associations between chronic conditions; quality of life and life expectancy in adulthood; and the trauma and stress associated with adverse childhood experiences, including physical or emotional abuse or neglect, deprivation, or exposure to violence. Less is known about the population-based epidemiology of adverse childhood experiences among US children. Using the 2011-12 National Survey of Children's Health, we assessed the prevalence of adverse childhood experiences and associations between them and factors affecting children's development and lifelong health. After we adjusted for confounding factors, we found lower rates of school engagement and higher rates of chronic disease among children with adverse childhood experiences. Our findings suggest that building resilience-defined in the survey as "staying calm and in control when faced with a challenge," for children ages 6-17-can ameliorate the negative impact of adverse childhood experiences. We found higher rates of school engagement among children with adverse childhood experiences who demonstrated resilience, as well as higher rates of resilience among children with such experiences who received care in a family-centered medical home. We recommend a coordinated effort to fill knowledge gaps and translate existing knowledge about adverse childhood experiences and resilience into national, state, and local policies, with a focus on addressing childhood trauma in health systems as they evolve during ongoing reform.

2015-12-01

Patients with OCD are impaired in multiple domains of functioning and quality of life. While associated psychopathology complaints and neuropsychological deficits were reported, the subjective experience of general fatigue and mental fatigue was scarcely investigated. In this single-center case-control study we compared 50 non-depressed OCD outpatients consecutively recruited and 50 panic disorder (PD) outpatients, to determine whether they experienced fatigue differently. Assessment consisted of structured clinical interview for DSM-IV criteria by using the SCID-I and the SCID-II. Symptom severity was assessed using the Yale-Brown Obsessive-Compulsive Scale, the Hamilton Anxiety Rating Scale, the Hamilton Depression Rating Scale, the Clinical Global Impressions Scale, severity and the Global Assessment of Functioning Scale. Fatigue was assessed by using the Multidimensional Fatigue Inventory (MFI). Regarding MFI physical fatigue, an OR of 0.196 (95 % CI 0.080-0.478) was found, suggesting that its presence is associated with lower odds of OCD compared to PD. The same can be said for MFI mental fatigue, as an OR of 0.138 (95 % CI 0.049-0.326) was found, suggesting that its presence is associated with lower odds of OCD. Notably, OCD patients with OCDP co-morbidity reported higher scores of mental fatigue. In this study fatigue, including mental fatigue, seems not to be a prominent experience among adult non-depressed OCD patients.

An improved methodology for quantitatively evaluating failure risk of spaceflight systems to assess flight readiness and identify risk control measures is presented. This methodology, called Probabilistic Failure Assessment (PFA), combines operating experience from tests and flights with engineering analysis to estimate failure risk. The PFA methodology is of particular value when information on which to base an assessment of failure risk, including test experience and knowledge of parameters used in engineering analyses of failure phenomena, is expensive or difficult to acquire. The PFA methodology is a prescribed statistical structure in which engineering analysis models that characterize failure phenomena are used conjointly with uncertainties about analysis parameters and/or modeling accuracy to estimate failure probability distributions for specific failure modes, These distributions can then be modified, by means of statistical procedures of the PFA methodology, to reflect any test or flight experience. Conventional engineering analysis models currently employed for design of failure prediction are used in this methodology. The PFA methodology is described and examples of its application are presented. Conventional approaches to failure risk evaluation for spaceflight systems are discussed, and the rationale for the approach taken in the PFA methodology is presented. The statistical methods, engineering models, and computer software used in fatigue failure mode applications are thoroughly documented.

A recent hypothesis is that suicidality in schizophrenia may be linked to the patients' altered basic self-awareness or sense of self, termed self-disorders (SDs). The aim of the study was to investigate whether SDs in first-episode schizophrenia spectrum disorders are related to suicidality and whether this relationship is independent of or mediated by depression or other standard clinical measures. Self-disorders were assessed in 49 patients with first-episode schizophrenia by means of the Examination of Anomalous Self-Experience (EASE) instrument. Symptoms severity and functioning were assessed using the Structured Clinical Interview for the Positive and Negative Syndrome Scale, Calgary Depression Scale for Schizophrenia, and Global Assessment of Functioning-Split Version. Suicidality was measured by the Calgary Depression Scale for Schizophrenia item 8. Analyses detected a significant association between current suicidality, current depression, and SDs as measured by the EASE. The effect of SDs on suicidal ideation appeared to be mediated by depression. The interaction between anomalous self-experiences and depression could be a rational clinical target for the prevention of suicidality in the early phases of schizophrenia and supports the rationale for including assessment of SDs in early intervention efforts.

Immunotherapy represents a promising area of therapy among neuro-oncology patients. However, early phase studies reveal unique challenges associated with assessment of radiological changes reflecting delayed responses or therapy-induced inflammation. Clinical benefit, including long-term survival and tumor regression, can still occur following initial apparent progression or appearance of new lesions. Refinement of response assessment criteria for neuro-oncology patients undergoing immunotherapy is therefore warranted. A multinational and multidisciplinary panel of neuro-oncology immunotherapy experts describes immunotherapy response assessment for neuro-oncology (iRANO) criteria that are based on guidance for determination of tumor progression outlined by the immune-related response criteria (irRC) and the response assessment in neuro-oncology (RANO) working group. Among patients who demonstrate imaging findings meeting RANO criteria for progressive disease (PD) within six months of initiating immunotherapy including the development of new lesions, confirmation of radiographic progression on follow-up imaging is recommended provided that the patient is not significantly worse clinically. The proposed criteria also include guidelines for use of corticosteroids. The role of advanced imaging techniques and measurement of clinical benefit endpoints including neurologic and immunologic functions are reviewed. The iRANO guidelines put forth herein will evolve successively to improve their utility as further experience from immunotherapy trials in neuro-oncology accumulate. PMID:26545842

Although medical colleges in Iraq started recently to increasingly use small group teaching approach, there is limited research on the challenges, opportunities and needs of small group teaching in Iraq particularly in Kurdistan Region. Therefore, this study was aimed to assess the small group teaching experience in the 4(th) and 5(th) year of study in Hawler College of Medicine with a focus on characterizing the impressions of faculty members about how small group teaching is proceeding in the college. A qualitative study based on semi-structured interviews with 20 purposively selected faculty members was conducted. An interview guide was used for data collection that was around different issues related to small group teaching in medical education including planning, preparation, positive aspects, problems facing its implementation, factors related to it and recommendations for improvement. Qualitative data analysis comprised identifying themes that emerged from the review of transcribed interviews. Participants reported some positive experience and a number of positive outcomes related to this experience including better controlling the class, enhancing students' understanding of the subject, increasing interaction in the class, increasing the students' confidence, enhancing more contact between teachers and students, improving the presentation skills of the students and improving the teacher performance. The participants emphasized poor preparation and planning for application of this system and highlighted a number of problems and challenges facing this experience particularly in terms of poor infrastructure and teaching facilities, poor orientation of students and teachers, inadequate course time for some subjects and shortage of faculty members in a number of departments. The main suggestions to improve this experience included improving the infrastructure and teaching facilities, using more interactive teaching methods and better organization and management of the system. Despite what the faculty perceived as the college's failure to provide physical settings or training for small group learning to the faculty and the students, the faculty members were able to articulate positive experiences and outcomes associated with their college's efforts to introduce teaching in smaller group sessions.

This study aimed to explore the relationship between traumatic history, dissociative phenomena, absorption and quality of life among a population of channelers, in comparison with a population of non-channelers with similar traumatic history. The study sample included 150 women. The measures included Traumatic Experiences Scale, Dissociative Experience Scale, Absorption Scale, Brief Symptom Inventory and Quality of Life (QOL) Assessment. Channelers presented significantly higher levels of dissociation, absorption and psychological health compared to the other group. Dissociation and absorption were trauma-related only among the comparison group. Hence, dissociation has different qualities among different people, and spiritual practice contributes to QOL.

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

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

Background Colorectal cancer (CRC) incidence and mortality rates are increased and CRC screening rates are lower among Appalachia Ohio residents. Objectives We sought to describe 1) a partnership of cancer researchers and community members that developed county-specific media campaigns to improve CRC screening rates (intervention) and fruit and vegetable consumption (control) and 2) the experience of community members featured in the campaigns. Methods Community members assisted with campaign-development, were featured in campaigns, identified locations for materials, and promoted the campaigns. Campaigns included billboards, posters, and information in local newspapers. A mailed survey assessed featured community members’ experiences in the campaigns. Lessons Learned Ongoing communication among members of the partnership was critical to successful community-level campaigns. Featured community members had mostly positive experiences about being included in the campaigns. Conclusions Having a shared vision, ongoing trust, and good communication are essential elements to maintaining a viable academic-community partnership. PMID:26412757

Competency to stand trial relates directly to legal rights of the appraised individual as well as whether criminal procedure can be carried out smoothly. Foreign scholars have conducted a large number of theoretical researches, and developed a series of standardized evaluation tools. However, the assessment on competency to stand trial has mainly focused on medical criteria in China for a long time, and most cases were judged by forensic psychiatrists' experience. Recently, Chinese scholars have started the initial research on standardized evaluation. This paper reviews the notion of competency to stand trial, the evaluation criteria, and the assessment tools domestically and abroad. The main focus is on foreign assessment tools, which included three categories. First category includes checklist, self-report questionnaires and sentence-completion tasks. Second category is the interview-based instruments without criterion-based scoring. Last category is the interview-based instruments with criterion-based scoring. This literature may be helpful for further research and standardization on assessment tools of competency to stand trial of mentally disordered offenders.

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

Purpose A 2-arm, double-blinded, randomized trial to evaluate the effect of 0.1% mometasone furoate (MMF) on acute skin-related toxicity in patients undergoing breast or chest wall radiotherapy. Methods and Materials Patients with ductal carcinoma in situ or invasive breast carcinoma receiving external beam radiotherapy to breast or chest wall were randomly assigned to daily apply 0.1% MMF or placebo cream. Primary study end point was provider-assessed maximum grade of Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 radiation dermatitis. Secondary end points included provider-assessed CTCAE grade 3 or greater radiation dermatitis and adverse-event monitoring. Patient-reported outcome (PRO) measures included the Skindex-16, the Skin Toxicity Assessment Tool, a Symptom Experience Diary, and quality of life self-assessment. Assessment was performed at baseline, weekly during radiotherapy, and for 2 weeks after radiotherapy. Results In total, 176 patients were enrolled from September 21, 2007 through December 7, 2007. The provider-assessed primary end point showed no difference in mean maximum grade of radiation dermatitis by treatment arm (1.2 for MMF vs 1.3 for placebo; P=.18). CTCAE toxicity was greater in placebo group (P=.04), primarily from pruritus. For PRO measures, the maximum Skindex-16 score for MMF group showed less itching (P=.008), less irritation (P=.01), less symptom persistence or recurrence (P=.02), and less annoyance with skin problems (P=.04); the group's maximum Skin Toxicity Assessment Tool score showed less burning sensation (P=.02) and less itching (P=.002). Conclusion Patients receiving daily MMF during radiotherapy may experience reduced acute skin toxicity in comparison to placebo. PMID:20800381

NASA Astrophysics Data System (ADS)

Joyce, Alexander Augusto

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

Atmospheric stability and complex terrain: comparing measurements and CFD

For wind resource assessment, the wind industry is increasingly relying on Computational Fluid Dynamics models that focus on modeling the airflow in a neutrally stratified surface layer. So far, physical processes that are specific to the atmospheric boundary layer, for example the Coriolis force, buoyancy forces and heat transport, are mostly ignored in state-of-the-art flow solvers. In order to decrease the uncertainty of wind resource assessment, the effect of thermal stratification on the atmospheric boundary layer should be included in such models. The present work focuses on non-neutral atmospheric flow over complex terrain including physical processes like stability and Coriolis force. We examine the influence of these effects on the whole atmospheric boundary layer using the DTU Wind Energy flow solver EllipSys3D. To validate the flow solver, measurements from Benakanahalli hill, a field experiment that took place in India in early 2010, are used. The experiment was specifically designed to address the combined effects of stability and Coriolis force over complex terrain, and provides a dataset to validate flow solvers. Including those effects into EllipSys3D significantly improves the predicted flow field when compared against the measurements.

Development and Testing of Neutron Cross Section Covariance Data for SCALE 6.2

Marshall, William BJ J; Williams, Mark L; Wiarda, Dorothea

2015-01-01

Neutron cross-section covariance data are essential for many sensitivity/uncertainty and uncertainty quantification assessments performed both within the TSUNAMI suite and more broadly throughout the SCALE code system. The release of ENDF/B-VII.1 included a more complete set of neutron cross-section covariance data: these data form the basis for a new cross-section covariance library to be released in SCALE 6.2. A range of testing is conducted to investigate the properties of these covariance data and ensure that the data are reasonable. These tests include examination of the uncertainty in critical experiment benchmark model k eff values due to nuclear data uncertainties, asmore » well as similarity assessments of irradiated pressurized water reactor (PWR) and boiling water reactor (BWR) fuel with suites of critical experiments. The contents of the new covariance library, the testing performed, and the behavior of the new covariance data are described in this paper. The neutron cross-section covariances can be combined with a sensitivity data file generated using the TSUNAMI suite of codes within SCALE to determine the uncertainty in system k eff caused by nuclear data uncertainties. The Verified, Archived Library of Inputs and Data (VALID) maintained at Oak Ridge National Laboratory (ORNL) contains over 400 critical experiment benchmark models, and sensitivity data are generated for each of these models. The nuclear data uncertainty in k eff is generated for each experiment, and the resulting uncertainties are tabulated and compared to the differences in measured and calculated results. The magnitude of the uncertainty for categories of nuclides (such as actinides, fission products, and structural materials) is calculated for irradiated PWR and BWR fuel to quantify the effect of covariance library changes between the SCALE 6.1 and 6.2 libraries. One of the primary applications of sensitivity/uncertainty methods within SCALE is the assessment of similarities between benchmark experiments and safety applications. This is described by a c k value for each experiment with each application. Several studies have analyzed typical c k values for a range of critical experiments compared with hypothetical irradiated fuel applications. The c k value is sensitive to the cross-section covariance data because the contribution of each nuclide is influenced by its uncertainty; large uncertainties indicate more likely bias sources and are thus given more weight. Changes in c k values resulting from different covariance data can be used to examine and assess underlying data changes. These comparisons are performed for PWR and BWR fuel in storage and transportation systems.« less

The majority of research examining Undergraduate Research Experiences focuses singularly on student-reported outcomes, often overlooking assessment of the mentor role in student learning and outcomes following these experiences. The goal of the current study was to examine the student-mentor dyad at the beginning and end of a 10-week summer research experience for American Indian undergraduates utilizing a series of actor-partner interdependence models within SEM. Participants included 26 undergraduate interns (50% American Indian; 50% American Indian and White; M age = 24) and 27 mentors (89% White; M age = 47). Findings indicated that in accounting for all potential paths between students and mentors, the partner path between mentor beliefs at the beginning of the program and students’ skills related to autonomy (β =.59, p = .01) and academic resilience (β =.44, p = .03) at the end of the program were significant. These findings suggest the important impact of mentor beliefs on student outcomes, a relationship that should be adequately assessed and continue to be important focus of undergraduate research experiences. Findings further indicate the important role of mentors for American Indian undergraduates. PMID:28289486

Evaluation of results of cell electrophoresis experiments on space shuttle STS-3 including pre-flight and post-flight laboratory experiments

The objectives of the red blood cell experiments were to provide a visual check on the electrophoretic process and especially electroosmotic flow in space as well as to provide test separations of non-degradable standard particles for comparison with the separations of the three viable cell types studied on the Apollo-Soyuz Test Project. Determination of the maximum concentrations of cells that can be separated in column electrophore was a significant goal. Two of the eight columns were available for red cell experiments, so two concentrations of human and rabbit RBC mixtures were used. The objectives of another experiment were to evaluate the reproducibility of microgravity electrophoretic separation of living kidney cells, to separate cells with highly viability despite two freeze-thaw cycles, and to optimize the physical conditions of cell separation. Owing to the uncertain heterogeneity of the starting material, the experimental design does not assess resolution in microgravity, but improved separability was sought in comparison to density-gradient electrophoresis or continuous-flow electrophoresis. Efforts were made to increase cell yield and cell viability and to assess reproducibility directly.

Purpose To understand racial/ethnic minority adolescent females’ experiences with the vaginal ring. Methods We conducted in-depth interviews with a clinic-based sample of 32 young women aged 15–24 years who had used the vaginal ring. Results Qualitative analysis using grounded theory revealed that adolescents undergo a multi-stage process when trying the ring and adopting ring use. These stages include hearing about the ring, initial reactions, first experiences with insertion and removal, and first sexual experiences. Adolescents subsequently enter an assessment and adjustment stage in which they decide whether to adopt or discontinue ring use. Ultimately they share their experiences with friends. Conclusions The model developed provides a context within which providers may advise adolescents as they begin use of the ring. Some specific recommendations are offered. PMID:18565439

To systematically review the measurement properties of instruments assessing participation in young people with autism spectrum disorder (ASD). A search was performed in MEDLINE, PsycINFO, and PubMed combining three constructs ('ASD', 'test of participation', 'measurement properties'). Results were restricted to articles including people aged 6 to 29 years. The 2539 identified articles were independently screened by two reviewers. For the included articles, data were extracted using standard forms and their risk of bias was assessed. Nine studies (8 cross-sectional) met the inclusion criteria, providing information on seven different instruments. The total sample included 634 participants, with sex available for 600 (males=494; females=106) and age available for 570, with mean age for these participants 140.58 months (SD=9.11; range=36-624). Included instruments were the school function assessment, vocational index, children's assessment of participation and enjoyment/preferences for activities of children, experience sampling method, Pediatric Evaluation of Disability Inventory, Computer Adaptive Test, adolescent and young adult activity card sort, and Patient-Reported Outcomes Measurement Information System parent-proxy peer relationships. Seven studies assessed reliability and validity; good properties were reported for half of the instruments considered. Most studies (n=6) had high risk of bias. Overall the quality of the evidence for each tool was limited. Validation of these instruments, or others that comprehensively assess participation, is needed. Future studies should follow recommended methodological standards. Seven instruments have been used to assess participation in young people with autism. One instrument, with excellent measurement properties in one study, does not comprehensively assess participation. Studies of three instruments that incorporate a more comprehensive assessment of participation have methodological limitations. Overall, limited evidence exists regarding measurement properties of participation assessments for young people with autism. © 2017 Mac Keith Press.

Capsule modeling of high foot implosion experiments on the National Ignition Facility

Clark, D. S.; Kritcher, A. L.; Milovich, J. L.

This study summarizes the results of detailed, capsule-only simulations of a set of high foot implosion experiments conducted on the National Ignition Facility (NIF). These experiments span a range of ablator thicknesses, laser powers, and laser energies, and modeling these experiments as a set is important to assess whether the simulation model can reproduce the trends seen experimentally as the implosion parameters were varied. Two-dimensional (2D) simulations have been run including a number of effects—both nominal and off-nominal—such as hohlraum radiation asymmetries, surface roughness, the capsule support tent, and hot electron pre-heat. Selected three-dimensional simulations have also been run tomore » assess the validity of the 2D axisymmetric approximation. As a composite, these simulations represent the current state of understanding of NIF high foot implosion performance using the best and most detailed computational model available. While the most detailed simulations show approximate agreement with the experimental data, it is evident that the model remains incomplete and further refinements are needed. Nevertheless, avenues for improved performance are clearly indicated.« less

Background In this study, we explored the ability of the Dissociative Experiences Scale (DES) to catch detachment and compartmentalization symptoms. Participants and methods The DES factor structure was evaluated in 768 psychiatric patients (546 women and 222 men) and in 2,403 subjects enrolled in nonpsychiatric settings (1,857 women and 546 men). All participants were administered the Italian version of DES. Twenty senior psychiatric experts in the treatment of dissociative symptoms independently assessed the DES items and categorized each of them as follows: “C” for compartmentalization, “D” for detachment, and “NC” for noncongruence with either C or D. Results Confirmatory factor analysis supported the three-factor structure of DES in both clinical and nonclinical samples and its invariance across the two groups. Moreover, factor analyses results overlapped with those from the expert classification procedure. Conclusion Our results showed that DES can be used as a valid instrument for clinicians to assess the frequency of different types of dissociative experiences including detachment and compartmentalization.

Halle, J W; Baer, D M; Spradlin, J E

1981-01-01

In Experiment 1, classroom teachers were taught to delay their offers of help in naturally occurring situations, and thereby to provide additional opportunities for language use by six moderately retarded language-delayed children. The teachers introduced this delay technique in a multiple-baseline design across the six children. As delays were used, child verbal initiations increased. Follow-up assessment showed that teachers were maintaining greater than baseline levels of the delay technique after 10 weeks. Experiment 2 replicated the findings of Experiment 1, and included a more thorough maintenance assessment, while focusing on teachers' generalization of the delay technique. Teachers were found to generalize their use of delay to 56% of their monitored untaught opportunities. The two experiments show that (a) the delay technique is quick to teach and simple to implement, (b) delays do provide opportunities for children to initiate, (c) teachers can generalize their use of delay to novel self-selected situations, and (d) teachers can maintain their use of delays over time.

This study summarizes the results of detailed, capsule-only simulations of a set of high foot implosion experiments conducted on the National Ignition Facility (NIF). These experiments span a range of ablator thicknesses, laser powers, and laser energies, and modeling these experiments as a set is important to assess whether the simulation model can reproduce the trends seen experimentally as the implosion parameters were varied. Two-dimensional (2D) simulations have been run including a number of effects—both nominal and off-nominal—such as hohlraum radiation asymmetries, surface roughness, the capsule support tent, and hot electron pre-heat. Selected three-dimensional simulations have also been run tomore » assess the validity of the 2D axisymmetric approximation. As a composite, these simulations represent the current state of understanding of NIF high foot implosion performance using the best and most detailed computational model available. While the most detailed simulations show approximate agreement with the experimental data, it is evident that the model remains incomplete and further refinements are needed. Nevertheless, avenues for improved performance are clearly indicated.« less

Global bias reliability in dogs (Canis familiaris).

Dogs enrolled in a previous study were assessed two years later for reliability of their local/global preference in a discrimination test with the same hierarchical stimuli used in the previous study (Experiment 1) and with a novel stimulus (Experiment 2). In Experiment 1, dogs easily re-learned to discriminate the positive stimulus; their individual global/local choices were stable compared to the previous study; and an overall clear global bias was found. In Experiment 2, dogs were slower in acquiring the initial discrimination task; the overall global bias disappeared; and, individually, dogs tended to make inverse choices compared to the original study. Spontaneous attention toward the test stimulus resembling the global features of the probe stimulus was the main factor affecting the likeliness of a global choice of our dogs, regardless of the type of experiment. However, attention to task-irrelevant elements increased at the expense of attention to the stimuli in the test phase of Experiment 2. Overall, the results suggest that the stability of global bias in dogs depends on the characteristics of the assessment contingencies, likely including the learning requirements of the tasks. Our results also clearly indicate that attention processes have a prominent role on dogs' global bias, in agreement with previous findings in humans and other species.

To compare patient experiences and disparities for older adults with depressive symptoms in managed care (Medicare Advantage [MA]) versus Medicare Fee-for-Service (FFS). Data came from the 2010 Medicare CAHPS survey, to which 220,040 MA and 135,874 FFS enrollees aged 65 and older responded. Multivariate linear regression was used to test whether case-mix-adjusted associations between depressive symptoms and patient experience differed for beneficiaries in MA versus FFS. Dependent measures included four measures of beneficiaries' experiences with doctors (e.g., reports of doctor communication) and seven measures of beneficiaries' experiences with plans (e.g., customer service). Beneficiaries with depressive symptoms reported worse experiences than those without depressive symptoms regardless of coverage type. For measures assessing interactions with the plan (but not for measures assessing interactions with doctors), the disadvantage for beneficiaries with versus without depressive symptoms was larger in MA than in FFS. Disparities in care experienced by older Medicare beneficiaries with depressive symptoms tend to be more negative in managed care than in FFS. Efforts are needed to identify and address the barriers these beneficiaries encounter to help them better traverse the managed care environment. © Health Research and Educational Trust.

Models and Measurement Intercomparison II (MM II) summarizes the intercomparison of results from model simulations and observations of stratospheric species. Representatives from twenty-three modeling groups using twenty-nine models participated in these MM II exercises between 1996 and 1999. Twelve of the models were two- dimensional zonal-mean models while seventeen were three-dimensional models. This was an international effort as seven were from outside the United States. Six transport experiments and five chemistry experiments were designed for various models. Models participating in the transport experiments performed simulations of chemically inert tracers providing diagnostics for transport. The chemistry experiments involved simulating the distributions of chemically active trace cases including ozone. The model run conditions for dynamics and chemistry were prescribed in order to minimize the factors that caused differences in the models. The report includes a critical review of the results by the participants and a discussion of the causes of differences between modeled and measured results as well as between results from different models, A sizable effort went into preparation of the database of the observations. This included a new climatology for ozone. The report should help in evaluating the results from various predictive models for assessing humankind perturbations of the stratosphere.

Preliminary Development of a Multidimensional Semantic Patient Experience Measurement Questionnaire.

PubMed

Kleiss, James A

2016-10-01

The purpose of this research was to assess the utility and reliability of a multidimensional patient experience measurement questionnaire in a clinical setting. Patient experience has emerged as an important metric for quality of healthcare. A number of separate concepts have been used to measure patient experience, but psychological research suggests that subjective experience is actually a composite of several independent concepts including: (a) evaluation/valence, (b) potency/control, (c) activity/arousal, and (d) novelty. The present research evaluates the reliability of a multidimensional patient experience measurement questionnaire in a clinical setting. A multidimensional semantic differential questionnaire was developed to measure the four underlying semantic dimensions of patient experience mentioned above. A group of 60 patients used the questionnaire to assess prescan expectations and postscan experience of a magnetic resonance scan. Data for one patient were deleted because their scan was interrupted. Results revealed more positive evaluation/valence, higher potency/control, and lower activity/arousal for postscan ratings compared to prescan expectations. Ratings of novelty were neutral in both the prescan and the postscan conditions. Subsequent analysis suggested that internal consistency for some concepts could be improved by replacing several specific rating scales. Present results provide evidence of the utility and reliability of a multidimensional semantic questionnaire for measuring patient experience in an actual clinical setting. Recommendations to improve internal consistency for the concepts potency/control, activity/arousal, and novelty were also provided. © The Author(s) 2016.

Radio-ecological characterization and radiological assessment in support of regulatory supervision of legacy sites in northwest Russia.

PubMed

Sneve, M K; Kiselev, M; Shandala, N K

2014-05-01

The Norwegian Radiation Protection Authority has been implementing a regulatory cooperation program in the Russian Federation for over 10 years, as part of the Norwegian government's Plan of Action for enhancing nuclear and radiation safety in northwest Russia. The overall long-term objective has been the enhancement of safety culture and includes a special focus on regulatory supervision of nuclear legacy sites. The initial project outputs included appropriate regulatory threat assessments, to determine the hazardous situations and activities which are most in need of enhanced regulatory supervision. In turn, this has led to the development of new and updated norms and standards, and related regulatory procedures, necessary to address the often abnormal conditions at legacy sites. This paper presents the experience gained within the above program with regard to radio-ecological characterization of Sites of Temporary Storage for spent nuclear fuel and radioactive waste at Andreeva Bay and Gremikha in the Kola Peninsula in northwest Russia. Such characterization is necessary to support assessments of the current radiological situation and to support prospective assessments of its evolution. Both types of assessments contribute to regulatory supervision of the sites. Accordingly, they include assessments to support development of regulatory standards and guidance concerning: control of radiation exposures to workers during remediation operations; emergency preparedness and response; planned radionuclide releases to the environment; development of site restoration plans, and waste treatment and disposal. Examples of characterization work are presented which relate to terrestrial and marine environments at Andreeva Bay. The use of this data in assessments is illustrated by means of the visualization and assessment tool (DATAMAP) developed as part of the regulatory cooperation program, specifically to help control radiation exposure in operations and to support regulatory analysis of management options. For assessments of the current radiological situation, the types of data needed include information about the distribution of radionuclides in environmental media. For prognostic assessments, additional data are needed about the landscape features, on-shore and off-shore hydrology, geochemical properties of soils and sediments, and possible continuing source terms from continuing operations and on-site disposal. It is anticipated that shared international experience in legacy site characterization can be useful in the next steps. Although the output has been designed to support regulatory evaluation of these particular sites in northwest Russia, the methods and techniques are considered useful examples for application elsewhere, as well as providing relevant input to the International Atomic Energy Agency's international Working Forum for the Regulatory Supervision of Legacy Sites.

ISOGAME is designed and developed to assess quantitatively the impact of new observation systems on the capability of imaging and modeling the ionosphere. With ISOGAME, one can perform observation system simulation experiments (OSSEs). A typical OSSE using ISOGAME would involve: (1) simulating various ionospheric conditions on global scales; (2) simulating ionospheric measurements made from a constellation of low-Earth-orbiters (LEOs), particularly Global Navigation Satellite System (GNSS) radio occultation data, and from ground-based global GNSS networks; (3) conducting ionospheric data assimilation experiments with the Global Assimilative Ionospheric Model (GAIM); and (4) analyzing modeling results with visualization tools. ISOGAME can provide quantitative assessment of the accuracy of assimilative modeling with the interested observation system. Other observation systems besides those based on GNSS are also possible to analyze. The system is composed of a suite of software that combines the GAIM, including a 4D first-principles ionospheric model and data assimilation modules, an Internal Reference Ionosphere (IRI) model that has been developed by international ionospheric research communities, observation simulator, visualization software, and orbit design, simulation, and optimization software. The core GAIM model used in ISOGAME is based on the GAIM++ code (written in C++) that includes a new high-fidelity geomagnetic field representation (multi-dipole). New visualization tools and analysis algorithms for the OSSEs are now part of ISOGAME.

Objective The current study considered protective strategy use at various points in time for divorcing mothers with a range of marital violence experiences (including no history of violence and different types of violence). Method Divorcing mothers (N = 170) from one Midwestern county participated in two in-person interviews that included structured assessments of intimate partner violence (IPV) during the last year of marriage and use of protective strategies at three time points – last year of marriage and at separation (both assessed at Time 1) and since the first interview (at a three month follow-up). Results Divorcing mothers, regardless of marital violence experience, used an array of private and public protective strategies during the last year of marriage, at separation, and at the three-month follow up interview. In general, mothers who experienced coercive controlling violence reported using more protective strategies than mothers who experienced situational couple violence or no violence. Strategy use peaked at separation with an increase in public strategy use. Conclusions All divorcing mothers use a range of active coping strategies over time, yet findings emphasize the importance of making distinctions between types of IPV so that divorcing mothers receive individualized resources and support that best meet their needs and minimize potentials risks and losses as they navigate the divorce process.

The purpose of this study was to assess the prevalence of childhood victimization experiences in a sample of young adults in St. Petersburg, Russia. The study sample included 743 students aged 19 to 25 from 15 universities in St. Petersburg, Russia. All of the study participants completed a reliable questionnaire assessing the following types of childhood victimization: conventional crime, child maltreatment, peer victimization, sexual victimization, and witnessing violence. Participation in the study was anonymous. High rates of victimization and exposure to violence were reported by the study participants. The majority of the sample experienced at least one type of victimization during childhood or adolescence, and poly-victimization was reported frequently. The most common type of victimization reported was peer or sibling assault (66.94%), followed by witnessing an assault without weapon (63.91%), personal theft (56.19%), vandalism (56.06%), and emotional bullying (49.99%). Sexual assault by a known adult was reported by 1.45% males and 5.16% of females. This study provides new information on the scope of childhood victimization experiences in Russia. Further research is warranted, including epidemiological research with representative data across the country and studies of the impact of trauma and victimization on mental health and well-being of Russian adults and children. © The Author(s) 2014.

The potential of natural laminar flow for significant drag reduction and improved efficiency for aircraft is assessed. Past experience with natural laminar flow as reported in published and unpublished data and personal observations of various researchers is summarized. Aspects discussed include surface contour, waviness, and smoothness requirements; noise and vibration effects on boundary layer transition, boundary layer stability criteria; flight experience with natural laminar flow and suction stabilized boundary layers; and propeller slipstream, rain, frost, ice and insect contamination effects on boundary layer transition. The resilient leading edge appears to be a very promising method to prevent leading edge insect contamination.

2017-01-01

Understanding factors associated with burnout among HIV/AIDS volunteers has long-ranging implications for community organizations and prevention. Using a cross-sectional sample of Latino gay/bisexual men and transgender people (N=309), we assess potential correlates of burnout identified by multiple theories, including factors associated with volunteering (experiences, motives) and contextual factors (stigma, sense of community). Reporting negative volunteering experiences was positively associated with burnout, while being motivated by personal HIV/AIDS experiences and having a greater sense of GLBT community was negatively related to burnout. The study highlights central challenges and opportunities to retain volunteers from marginalized communities. PMID:29422719

2015-01-01

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

The emergence of coherence over the course of decision making.

PubMed

Simon, D; Pham, L B; Le, Q A; Holyoak, K J

2001-09-01

Previous research has indicated that decision making is accompanied by an increase in the coherence of assessments of the factors related to the decision alternatives. In the present study, the authors investigated whether this coherence shift is obtained before people commit to a decision, and whether it is obtained in the course of a number of other processing tasks. College students were presented with a complex legal case involving multiple conflicting arguments. Participants rated agreement with the individual arguments in isolation before seeing the case and after processing it under various initial sets, including playing the role of a judge assigned to decide the case. Coherence shifts were observed when participants were instructed to delay making the decision (Experiment 1), to memorize the case (Experiment 2), and to comprehend the case (Experiment 3). The findings support the hypothesis that a coherence-generating mechanism operates in a variety of processing tasks, including decision making.

Pre-flight sensorimotor adaptation protocols for suborbital flight.

PubMed

Shelhamer, Mark; Beaton, Kara

2012-01-01

Commercial suborbital flights, which include 3-5 minutes of 0 g between hyper-g launch and landing phases, will present suborbital passengers with a challenging sensorimotor experience. Based on the results of neurovestibular research in parabolic and orbital flight, and the anticipated wide range of fitness and experience levels of suborbital passengers, neurovestibular disturbances are likely to be problematic in this environment. Pre-flight adaptation protocols might alleviate some of these issues. Therefore, we describe a set of sensorimotor tests to evaluate passengers before suborbital flight, including assessment of the angular vestibulo-ocular reflex (VOR), ocular skew and disconjugate torsion, subjective visual vertical, and roll vection. Performance on these tests can be examined for correlations with in-flight experience, such as motion sickness, disorientation, and visual disturbances, based on questionnaires and cabin video recordings. Through an understanding of sensorimotor adaptation to parabolic and orbital flight, obtained from many previous studies, we can then suggest appropriate pre-flight adaptation procedures.

Paternity leave experiences of NHS doctors.

Gordon, Hannah; Szram, Joanna

2013-10-01

This study assesses NHS doctors' experiences of paternity leave and evaluates whether practices have changed since the introduction of additional paternity leave (APL) in April 2011. An anonymised online survey designed to discover experiences and uptake of APL and ordinary paternity leave (OPL) was distributed to all members of the London Deanery Synapse® network. In total, 364 fathers responded. Their seniority ranged from foundation trainees to consultants. Following the formal introduction of OPL in 2003, the number of fathers taking any paternity leave increased (from 50% to 95.6%). The majority of respondents (76.7%) felt well supported by their employer. Since the introduction of APL, 3% of respondents took additional leave. Reasons for the low uptake of APL included the impracticalities of the law, poor awareness and perceived attitudes and implications for training. Problems with OPL included the inadequate provision of cover and difficulties in timing the leave appropriately.

2017-07-04

Transcatheter aortic valve replacement (TAVR) has been introduced into U.S. clinical practice with efforts to optimize outcomes and minimize the learning curve. The goal of this study was to assess the degree to which increasing experience during the introduction of this procedure, separated from other outcome determinants including patient and procedural characteristics, is associated with outcomes. The authors evaluated the association of hospital TAVR volume and patient outcomes for TAVR by using data from 42,988 commercial procedures conducted at 395 hospitals submitting to the Transcatheter Valve Therapy Registry from 2011 through 2015. Outcomes assessed included adjusted and unadjusted in-hospital major adverse events. Increasing site volume was associated with lower in-hospital risk-adjusted outcomes, including mortality (p < 0.02), vascular complications (p < 0.003), and bleeding (p < 0.001) but was not associated with stroke (p = 0.14). From the first case to the 400th case in the volume-outcome model, risk-adjusted adverse outcomes declined, including mortality (3.57% to 2.15%), bleeding (9.56% to 5.08%), vascular complications (6.11% to 4.20%), and stroke (2.03% to 1.66%). Vascular and bleeding volume-outcome associations were nonlinear with a higher risk of adverse outcomes in the first 100 cases. An association of procedure volume with risk-adjusted outcomes was also seen in the subgroup having transfemoral access. The initial adoption of TAVR into practice in the United States showed that increasing experience was associated with better outcomes. This association, whether deemed a prolonged learning curve or a manifestation of a volume-outcome relationship, suggested that concentrating experience in higher volume heart valve centers might be a means of improving outcomes.

Organizational readiness for change: Preceptor perceptions regarding early immersion of student pharmacists in health-system practice.

PubMed

Sanders, Kimberly A; Wolcott, Michael D; McLaughlin, Jacqueline E; D'Ostroph, Amanda; Shea, Christopher M; Pinelli, Nicole R

To examine preceptors' perceptions regarding readiness for change pre- and post-implementation of a pilot early immersion program engaging student pharmacists in direct patient care. Student pharmacists enrolled in the second professional year of a Doctor of Pharmacy degree program completed a four-week health-system introductory pharmacy practice experience (IPPE) which was modified to include direct patient care roles in operational (drug preparation and dispensing) and clinical (comprehensive medication management) pharmacy environments. Pharmacy preceptors with direct oversight for program implementation completed a pre/post Organizational Readiness for Implementing Change (ORIC) survey and a 50-min interview or focus group post-experience. The ORIC survey evaluates two dimensions of organizational readiness for change - change commitment and change efficacy. Additional items assessed included implementation needs, support, and perceived value of the change. ORIC survey constructs were compared before and after the experience. Interviews and focus groups were audio recorded, transcribed, and evaluated by constant comparative analysis. A mixed methods approach was used to triangulate findings and develop greater understanding of the ORIC survey results. Twenty pharmacy preceptors (37 ± 8 years of age, 60% female, 65% clinical pharmacist position, 70% prior preceptor experience) participated in the study. There were no significant changes in pre/post survey constructs, except for a decline in the perception of organizational change commitment (p < 0.001). Sub-analyses indicated the decline was associated with items assessing individual dedication and individual commitment to the change (p < 0.05 for both). Primary emerging themes from interviews included concerns about implementation requirements, contextual factors of the experience that affected implementation, and varying perceptions about the value of early immersion across preceptor roles. As pharmacy curricula immerse student pharmacists in practice earlier in their education, pharmacy departments can utilize the ORIC survey to identify preceptors' commitment and concerns to support the necessary changes for student pharmacist engagement.

Objective. To develop and apply a stepwise process to assess achievement of course learning objectives related to advanced pharmacy practice experiences (APPEs) preparedness and inform redesign of sequential skills-based courses. Design. Four steps comprised the assessment and redesign process: (1) identify skills critical for APPE preparedness; (2) utilize focus groups and course evaluations to determine student competence in skill performance; (3) apply course mapping to identify course deficits contributing to suboptimal skill performance; and (4) initiate course redesign to target exposed deficits. Assessment. Focus group participants perceived students were least prepared for skills within the Accreditation Council for Pharmacy Education's pre-APPE core domains of Identification and Assessment of Drug-related Problems and General Communication Abilities. Course mapping identified gaps in instruction, performance, and assessment of skills within aforementioned domains. Conclusions. A stepwise process that identified strengths and weaknesses of a course, was used to facilitate structured course redesign. Strengths of the process included input and corroboration from both preceptors and students. Limitations included feedback from a small number of pharmacy preceptors and increased workload on course coordinators.

Assessment of complex dissociative disorder patients and simulated dissociation in forensic contexts.

Brand, Bethany L; Webermann, Aliya R; Frankel, A Steven

Few assessors receive training in assessing dissociation and complex dissociative disorders (DDs). Potential differential diagnoses include anxiety, mood, psychotic, substance use, and personality disorders, as well as exaggeration and malingering. Individuals with DDs typically elevate on many clinical and validity scales on psychological tests, yet research indicates that they can be distinguished from DD simulators. Becoming informed about the testing profiles of DD individuals and DD simulators can improve the accuracy of differential diagnoses in forensic settings. In this paper, we first review the testing profiles of individuals with complex DDs and contrast them with DD simulators on assessment measures used in forensic contexts, including the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), Personality Assessment Inventory (PAI), and the Structured Inventory of Reported Symptoms (SIRS), as well as dissociation-specific measures such as the Dissociative Experiences Scale (DES) and Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D-R). We then provide recommendations for assessing complex trauma and dissociation through the aforementioned assessments. Copyright © 2016 Elsevier Ltd. All rights reserved.

Systems analysis develops and documents candidate mission and architectures, associated system concepts, enabling capabilities and investment strategies to achieve NASA s strategic objectives. The technology assessment process connects the mission and architectures to the investment strategies. In order to successfully implement a technology assessment, there is a need to collect, manipulate, analyze, document, and disseminate technology-related information. Information must be collected and organized on the wide variety of potentially applicable technologies, including: previous research results, key technical parameters and characteristics, technology readiness levels, relationships to other technologies, costs, and potential barriers and risks. This information must be manipulated to facilitate planning and documentation. An assessment is included of the programmatic and technical risks associated with each technology task as well as potential risk mitigation plans. Risks are assessed and tracked in terms of likelihood of the risk occurring and consequences of the risk if it does occur. The risk assessments take into account cost, schedule, and technical risk dimensions. Assessment data must be simplified for presentation to decision makers. The Systems Analysis and Concepts Directorate (SACD) at NASA Langley Research Center has a wealth of experience in performing Technology Assessment and Portfolio Analysis as this has been a business line since 1978.

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

Holos: A collaborative environment for similarity-based holistic approaches.

PubMed

Lê, Tâm Minh; Brard, Margot; Lê, Sébastien

2017-10-01

Through this article, we aim to introduce Holos-a new collaborative environment that allows researchers to carry out experiments based on similarity assessments between stimuli, such as in projective-mapping and sorting tasks. An important feature of Holos is its capacity to assess real-time individual processes during the task. Within the Holos environment, researchers can design experiments on its platform, which can handle four kinds of stimuli: concepts, images, sounds, and videos. In addition, researchers can share their study resources within the scientific community, including stimuli, experimental protocols, and/or the data collected. With a dedicated Android application combined with a tactile human-machine interface, subjects can perform experiments using a tablet to obtain similarity measures between stimuli. On the tablet, the stimuli are displayed as icons that can be dragged with one finger to position them, depending on the ways they are perceived. By recording the x,y coordinates of the stimuli while subjects move the icons, the obtained data can reveal the cognitive processes of the subjects during the experiment. Such data, named digit-tracking data, can be analyzed with the SensoMineR package. In this article, we describe how researchers can design an experiment, how subjects can perform the experiment, and how digit-tracking data can be statistically analyzed within the Holos environment. At the end of the article, a short exemplary experiment is presented.

Stratospheric controlled perturbation experiment: a small-scale experiment to improve understanding of the risks of solar geoengineering

2014-01-01

Although solar radiation management (SRM) through stratospheric aerosol methods has the potential to mitigate impacts of climate change, our current knowledge of stratospheric processes suggests that these methods may entail significant risks. In addition to the risks associated with current knowledge, the possibility of ‘unknown unknowns’ exists that could significantly alter the risk assessment relative to our current understanding. While laboratory experimentation can improve the current state of knowledge and atmospheric models can assess large-scale climate response, they cannot capture possible unknown chemistry or represent the full range of interactive atmospheric chemical physics. Small-scale, in situ experimentation under well-regulated circumstances can begin to remove some of these uncertainties. This experiment—provisionally titled the stratospheric controlled perturbation experiment—is under development and will only proceed with transparent and predominantly governmental funding and independent risk assessment. We describe the scientific and technical foundation for performing, under external oversight, small-scale experiments to quantify the risks posed by SRM to activation of halogen species and subsequent erosion of stratospheric ozone. The paper's scope includes selection of the measurement platform, relevant aspects of stratospheric meteorology, operational considerations and instrument design and engineering. PMID:25404681

Consolidated clinical practicum prepares pre-registration nursing students to function as beginning practitioners. The clinical competencies of final-year nursing students provide a key indication of professional standards of practice and patient safety. Thus, clinical assessment of nursing students is a crucial issue for educators and administrators. The aim of this systematic review was to explore the clinical competency assessment for undergraduate nursing students. PubMed, CINAHL, ScienceDirect, Web of Science, and EBSCO were systematically searched from January 2000 to December 2013. The systematic review was in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Published quantitative and qualitative studies that examined clinical assessment practices and tools used in clinical nursing education were retrieved. Quality assessment, data extraction, and analysis were completed on all included studies. This review screened 2073 titles, abstracts and full-text records, resulting in 33 included studies. Two reviewers assessed the quality of the included studies. Fourteen quantitative and qualitative studies were identified for this evaluation. The evidence was ordered into emergent themes; the overarching themes were current practices in clinical assessment, issues of learning and assessment, development of assessment tools, and reliability and validity of assessment tools. There is a need to develop a holistic clinical assessment tool with reasonable level of validity and reliability. Clinical assessment is a robust activity and requires collaboration between clinical partners and academia to enhance the clinical experiences of students, the professional development of preceptors, and the clinical credibility of academics.

Facial resurfacing with a CO 2 laser has been used for treatment of pathologic lesions and for cosmetic purposes. Postoperative complications and problems after laser resurfacing include infections, acneiform lesions, and pigment changes. This retrospective study describes the most common problems and complications in 105 patients and assesses postoperative pain in 38 patients. All patients received CO 2 laser resurfacing for treatment of malignant/premalignant lesions and had postoperative follow-up to assess problems and complications. Some had follow-up to assess postoperative pain. All patients had Fitzpatrick I-III skin types and underwent the same perioperative care regimen. There were 11 problems and 2 complications. Problems included infection, acneiform lesion/milia, and uncontrolled postoperative pain. Complications included hyperpigmentation. Among the postoperative pain group, 53% reported no pain and the rest had mild or moderate pain. Complications are rare. Infection and acneiform lesions/milia were the most common problems, as previously reported. Most patients do not experience postoperative pain. Copyright © 2016 Elsevier Inc. All rights reserved.

Pre-registration education programmes provide nursing students with the skills and knowledge to become safe and proficient practitioners. Assessment of students' competence is a fundamental part of these programmes and mentors play a crucial role. Mentors are registered nurses who have completed an appropriate mentorship programme in an approved higher education institution, and their main role includes teaching, supervising and assessing students' clinical competence. The role can be demanding and stressful, and mentors must maintain their workloads while supporting students. This article reports the results of the qualitative findings of a survey of mentorship practices ( Brown et al 2012 ). The findings suggest that mentors value support from link lecturers and practice education facilitators, especially when they experience difficulties with nursing students who do not have the required competencies to pass their placement.

Implementation of the IHR Joint External Evaluation: Taiwan's Experiences.

PubMed

Lo, Yi-Chun

In February 2016, the World Health Organization developed the Joint External Evaluation (JEE) tool to independently assess country capacity to prevent, detect, and respond to public health threats as part of the International Health Regulations (IHR) (2005) monitoring and evaluation framework. In light of this, the Taiwan government actively engaged at least 19 government agencies or institutions and voluntarily implemented the JEE. An External Assessment Team consisting of 6 US subject matter experts conducted the external evaluation, including site visits, from June 21 to July 1, 2016. The results, published on October 18, 2016, are useful and will be translated into actions and change in the system. Based on Taiwan's experiences, early stakeholder engagement and an experts' pre-JEE pilot visit would contribute to a successful JEE process.

The inadequate management of pain continues to be a significant problem for persons with cancer. Experts suggest that contributing factors include discrepancies in pain assessment, inadequate administration of opiate therapy, and insufficient documentation of the patient's pain experience. This study, part of a multidepartmental investigation into the adequacy of pain management in hospitalized patients, describes the pain experience of surgical oncology patients. Its correlational ex post facto design (n = 34) was guided by Loeser's model of pain. Randomly selected surgical oncology patients were interviewed using a structured format. The patient's primary nurse and physician simultaneously completed brief assessments of their perceptions of the patient's pain intensity. Data were analyzed using descriptive and correlational statistics, and implications for nursing practice and future nursing research are discussed.

Our team has developed an experimental platform to evaluate the x-ray-generated stress and impulse in materials. Experimental activities include x-ray source development, design of the sample mounting hardware and sensors interfaced to the National Ignition Facility's diagnostics insertion system, and system integration into the facility. This paper focuses on the X-ray Transport and Radiation Response Assessment (XTRRA) test cassettes built for these experiments. The test cassette is designed to position six samples at three predetermined distances from the source, each known to within ±1% accuracy. Built-in calorimeters give in situ measurements of the x-ray environment along the sample lines of sight. The measured accuracy of sample responses as well as planned modifications to the XTRRA cassette is discussed.

A new contrast-assisted method in microcirculation volumetric flow assessment

NASA Astrophysics Data System (ADS)

Lu, Sheng-Yi; Chen, Yung-Sheng; Yeh, Chih-Kuang

2007-03-01

Microcirculation volumetric flow rate is a significant index in diseases diagnosis and treatment such as diabetes and cancer. In this study, we propose an integrated algorithm to assess microcirculation volumetric flow rate including estimation of blood perfused area and corresponding flow velocity maps based on high frequency destruction/contrast replenishment imaging technique. The perfused area indicates the blood flow regions including capillaries, arterioles and venules. Due to the echo variance changes between ultrasonic contrast agents (UCAs) pre- and post-destruction two images, the perfused area can be estimated by the correlation-based approach. The flow velocity distribution within the perfused area can be estimated by refilling time-intensity curves (TICs) after UCAs destruction. Most studies introduced the rising exponential model proposed by Wei (1998) to fit the TICs. Nevertheless, we found the TICs profile has a great resemblance to sigmoid function in simulations and in vitro experiments results. Good fitting correlation reveals that sigmoid model was more close to actual fact in describing destruction/contrast replenishment phenomenon. We derived that the saddle point of sigmoid model is proportional to blood flow velocity. A strong linear relationship (R = 0.97) between the actual flow velocities (0.4-2.1 mm/s) and the estimated saddle constants was found in M-mode and B-mode flow phantom experiments. Potential applications of this technique include high-resolution volumetric flow rate assessment in small animal tumor and the evaluation of superficial vasculature in clinical studies.

To assess the effects of predeployment and deployment-related factors on dimensions of wellness following deployment. Prospective longitudinal study. The dependent variable was dimensions of wellness. Independent variables were measured in terms of modifiable, nonmodifiable, and military factors, such as sex, race/ethnicity, service branch, smoking status, and combat experience. A large military cohort participating in the Millennium Cohort Study. Included 10,228 participants who deployed in support of the operations in Iraq and Afghanistan. Dimensions of wellness were measured by using standardized instruments assessing self-reported physical health, mental health, and stress. Covariates were measured by using self-reported and electronic data. Factors of postdeployment wellness were assessed by using ordinal logistic regression. Most participants (78.7%) were categorized as "moderately well" post deployment. Significant modifiable predeployment predictors of postdeployment wellness included normal/underweight body mass index (odds ratio [OR] = 1.72, p < .05). Military factors significantly associated with wellness included not experiencing combat (OR = .56, p < .05), member of Air Force (OR = 2.02, p < .05) or Navy/Coast Guard (OR = 1.47, p < .05), and combat specialist occupation (OR = 1.22, p < .05). Multiple modifiable factors associated with postdeployment wellness were identified, which may help inform medical and military leadership on potential strategies to ensure a well force. Those trained in combat roles were more likely to be well post deployment though this apparent benefit was not conferred onto those reporting combat experiences.

In a longitudinal prospective study on 38 couples and their first child, we examined the influence of prenatally assessed psychological factors of the parents on somatic and psychic aspects of birth, the quality of the newly established parent-child relationship and the early development of the baby. Half-standardized psychoanalytic interviews with the couple (pre- and postnatally conducted, video-recorded), the Giessen test for couples, an evaluation of the parents' birth narratives and a parent questionnaire about functional symptoms of the baby were used. We found a high continuity between the pre- and the postnatal measurements of the partnership and the emotional experiences of the parents. Somatic complications of the birth event were not correlated with prenatally assessed psychological factors. But there exists a highly significant correlation between the mental representations and the relationships of the parents and the emotional experiences of birth, the early relationship between the parents and their baby and manifestations of functional disorders of the newborn. Relevant psychological and psychosocial aspects should be included in the medical care of pregnant women. One should listen to the imaginations and expectations of the parents about the future parentship, including ambivalent feelings. The father should also be seen for psychological assessment.

Hand hygiene (HH) prevents harmful contaminants spreading in settings including domestic, health care and food handling. Strategies to improve HH range from behavioural techniques through to automated sinks that ensure hand surface cleaning. This study aimed to assess user experience and acceptance towards a new automated sink, compared to a normal sink. An adapted version of the technology acceptance model (TAM) assessed each mode of handwashing. A within-subjects design enabled N = 46 participants to evaluate both sinks. Perceived Ease of Use and Satisfaction of Use were significantly lower for the automated sink, compared to the conventional sink (p < 0.005). Across the remaining TAM factors, there was no significant difference. Participants suggested design features including jet strength, water temperature and device affordance may improve HH technology. We provide recommendations for future HH technology development to contribute a positive user experience, relevant to technology developers, ergonomists and those involved in HH across all sectors. Practitioner Summary: The need to facilitate timely, effective hand hygiene to prevent illness has led to a rise in automated handwashing systems across different contexts. User acceptance is a key factor in system uptake. This paper applies the technology acceptance model as a means to explore and optimise the design of such systems.

To determine from the health care professionals perspective the impact on clinical practice of incorporating an assessment tool for primary care paediatric emergency. Qualitative study based on the collection of written documents. Twenty-four wide and detailed documents were collected. Thematic analysis was used. Participants were 9 nurses and 7 paediatricians, all with experience in the Paediatric Emergency Department. The results are grouped into three areas: perception of previous situation; benefits perceived; difficulties of the change process related to the triage instrument. The benefits perceived include the achievement of the objectives related to triage as well as collateral benefits for the organization and distribution of structural resources, adequacy of human resources, self-assessment and professional recognition, improvement of team communication and users service perception. The difficulties identified are related to the feasibility of using this instrument when patient flow is high and to the need of specialized training. All participants perceived more benefits than disadvantages, and both nurses and paediatricians experienced the process as a positive experience. The introduction of the assessment tool had a broader impact than expected.

Surveys indicate that practice and training in psychological assessment, and personality assessment (PA) to a lesser degree, has been stable or increasing over the past quarter-century. However, its future arguably remains threatened due to changes in doctoral training programs and beliefs in the field concerning the utility of PA for treatment success. To increase interest in and use of PA, studies of training methods that include trainees' perspectives are needed. This study evaluated the experiences of 10 graduate trainees and their clients who were trained in and conducted a brief Therapeutic Assessment (TA). Qualitative responses to a self-evaluation administered post-TA were coded using directed content analysis. Results indicated that trainees viewed TA/PA as having clinical utility; they had positive feelings about TA/PA, and they desired or intended to use or continue learning about TA/PA. Clients' responses reflected positive feelings about the TA, having gained new self-awareness or understanding, and having a positive relationship with the assessor. The findings suggest that teaching PA from a TA perspective could produce positive benefits for psychology trainees.

Surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI) are increasingly performed in octogenarian patients with severe aortic stenosis (AS), including those with high surgical risk. Postoperative delirium (PD) is a common and serious complication in older patients, characterised by reduced awareness, change in consciousness, disturbance in logical thinking and hallucinations. To explore how octogenarian patients experienced PD, a qualitative study was conducted including five women and five men between 81 and 88 years. The incidence of PD was assessed for five days using the Confusion Assessment Method. Cognitive function was assessed preoperatively and at a 6-month follow-up using the Mini-Mental State Examination. In-depth interviews were conducted 6-12 months post-discharge, transcribed, and analysed using Giorgi's phenomenological method. Postoperative delirium experiences were grouped into six themes: "Like dreaming while awake", "Disturbed experiences of time", "Existing in a twilight zone", "Trapped in medical tubes", "Moving between different surroundings" and "Meeting with death and the deceased". For the first time, we show that octogenarian patients who undergo SAVR or TAVI have strong and distressing memories of their delirious state that can persist for up to 12 months later. These findings provide valuable new information that will likely improve delivery of health services and enhance professional and empathic care of octogenarians after SAVR and TAVI.

Webster, Anthony J.; CCFE, Culham Science Centre, Abingdon OX14 3DB

2014-11-15

The generic question is considered: How can we determine the probability of an otherwise quasi-random event, having been triggered by an external influence? A specific problem is the quantification of the success of techniques to trigger, and hence control, edge-localised plasma instabilities (ELMs) in magnetically confined fusion (MCF) experiments. The development of such techniques is essential to ensure tolerable heat loads on components in large MCF fusion devices, and is necessary for their development into economically successful power plants. Bayesian probability theory is used to rigorously formulate the problem and to provide a formal solution. Accurate but pragmatic methods aremore » developed to estimate triggering probabilities, and are illustrated with experimental data. These allow results from experiments to be quantitatively assessed, and rigorously quantified conclusions to be formed. Example applications include assessing whether triggering of ELMs is a statistical or deterministic process, and the establishment of thresholds to ensure that ELMs are reliably triggered.« less

[Carl Arthur Scheunert's experiments on human nutrition, 1938-1943: boundary transgressions of a scientist under national socialism].

Joost, Hans-Georg

2012-01-01

Carl Arthur Scheunert (1879-1957) was a German scientist who supervised several studies with prisoners that were designed to assess the optimal vitamin and nutrient supply, and were conducted by his associate Karl-Heinz Wagner (1911-2007) from 1938 to 1943. This contribution describes the aims, results and conclusions of Scheunert's research 1923 to 1945 in comparison with the national and international vitamin research and its consequences for public health measures. Conditions and results of the human experiments are reconstructed and compared with similar studies performed in other countries. Burden as well as health risks for the study participants are assessed. In addition, it is discussed whether general rules for human experimentation were followed (e.g. informed consent and minimizing of health risks). Although the available documents support the conclusion that no deaths or lasting injuries were caused, the experiments violated ethical standards, in particular because of the conditions in the Waldheim prison including progressive deterioration of nutrition and health.

In 2030, when baby boomers reach 65 years of age and represent 18% of the population, it is anticipated that 67 million adults will have a diagnosis of arthritis increasing the demand for total hip and knee arthroplasty. With the growing emphasis on patient- and family-centered care, the aim of this project was to assess the patient experience of patients and families throughout the entire spectrum of the total joint replacement service line care at a university regional trauma hospital. A shadowing methodology as defined by the Institute for Health Improvement was utilized. Eight patient/family groups undergoing total joint replacements were shadowed. The mapped care experience included time, caregiver, activity, shadower observations, and impressions. Findings revealed inconsistencies in the delivery of patient- and family-centered care. Communication and interactions were predominantly provider-centric, with a focus on care routines versus the patient and family, and anticipation that care would be medically directed.

Risk management of biosimilars in oncology: each medicine is a work in progress.

2012-03-01

Drug licensing and drug safety monitoring for standard chemical entities have been established and are routinely used. These have resulted in a solid foundation of knowledge from which confident therapeutic decisions can be made. For many chemical entities, this advanced level of experience is also present for the generic products. The expertise surrounding the development of biosimilar competitor versions is increasing and progress is encouraging. To address the re-engineering and comparability complexities of biosimilars, the European Union imposed a requirement that risk management plans be included in the medications' marketing applications. This paper summarizes and discusses the circumstances complicating the public's view of drug safety, historical incidents during the transition from innovative to competitor products, as well as retrospective assessments of the development and post-marketing experiences thus far with two biosimilars. Through assessing the market entries and post-marketing experiences of biosimilars used in oncology, the healthcare field can better prepare for the next wave of comparator-products: biosimilar monoclonal antibodies.

A series of external contamination measurements were made on the Russian Mir Space Station. The Mir external contamination observations summarized in this paper were essential in assessing the system level impact of Russian Segment induced contamination on the International Space Station (ISS). Mir contamination observations include results from a series of flight experiments: CNES Comes-Aragatz, retrieved NASA camera bracket, Euro-Mir '95 ICA, retrieved NASA Trek blanket, Russian Astra-II, Mir Solar Array Return Experiment (SARE), etc. Results from these experiments were studied in detail to characterize Mir induced contamination. In conjunction with Mir contamination observations, Russian materials samples were tested for condensable outgassing rates in the U.S. These test results were essential in the characterization of Mir contamination sources. Once Mir contamination sources were identified and characterized, activities to assess the implications to ISS were implemented. As a result, modifications in Russian materials selection and/or usage were implemented to control contamination and mitigate risk to ISS.

In order to better understand academic achievement among deaf and hard-of-hearing students in different educational placements, an exploratory study examined the experiences of postsecondary students enrolled in mainstream programs (with hearing students) versus separate programs (without hearing students) at the same institution. The Course Experience Questionnaire, the Revised Approaches to Studying Inventory, and the Classroom Participation Questionnaire were utilized to obtain information concerning their perceptions, participation, and access to information in the classroom. Both groups were concerned with good teaching and the acquisition of generic skills. Both were motivated by the demands of their assessments and by a fear of failure while being alert to both positive and negative affect in their classroom interactions. Overall, students in separate classes were more positive about workload expectations, instructor feedback, and the choices they had in coursework. Students in mainstream classes were more positive about their acquisition of analytic skills (rather than rote memorization) and about their instructors' interest in them, including flexibility in methods of assessment.

An Experimental Comparison of Similarity Assessment Measures for 3D Models on Constrained Surface Deformation

2010-05-01

To address the issues in the area of design customization, this paper expressed the specification and application of the constrained surface deformation, and reported the experimental performance comparison of three prevail effective similarity assessment algorithms on constrained surface deformation domain. Constrained surface deformation becomes a promising method that supports for various downstream applications of customized design. Similarity assessment is regarded as the key technology for inspecting the success of new design via measuring the difference level between the deformed new design and the initial sample model, and indicating whether the difference level is within the limitation. According to our theoretical analysis and pre-experiments, three similarity assessment algorithms are suitable for this domain, including shape histogram based method, skeleton based method, and U system moment based method. We analyze their basic functions and implementation methodologies in detail, and do a series of experiments on various situations to test their accuracy and efficiency using precision-recall diagram. Shoe model is chosen as an industrial example for the experiments. It shows that shape histogram based method gained an optimal performance in comparison. Based on the result, we proposed a novel approach that integrating surface constrains and shape histogram description with adaptive weighting method, which emphasize the role of constrains during the assessment. The limited initial experimental result demonstrated that our algorithm outperforms other three algorithms. A clear direction for future development is also drawn at the end of the paper.

The present paper provides the background of a focused effort to assess uncertainties in predictions of heat flux and pressure in hypersonic flight (airbreathing or atmospheric entry) using state-of-the-art aerothermodynamics codes. The assessment is performed for four mission relevant problems: (1) shock turbulent boundary layer interaction on a compression corner, (2) shock turbulent boundary layer interaction due a impinging shock, (3) high-mass Mars entry and aerocapture, and (4) high speed return to Earth. A validation based uncertainty assessment approach with reliance on subject matter expertise is used. A code verification exercise with code-to-code comparisons and comparisons against well established correlations is also included in this effort. A thorough review of the literature in search of validation experiments is performed, which identified a scarcity of ground based validation experiments at hypersonic conditions. In particular, a shortage of useable experimental data at flight like enthalpies and Reynolds numbers is found. The uncertainty was quantified using metrics that measured discrepancy between model predictions and experimental data. The discrepancy data is statistically analyzed and investigated for physics based trends in order to define a meaningful quantified uncertainty. The detailed uncertainty assessment of each mission relevant problem is found in the four companion papers.

To investigate speech pathologists' current practice with adults who are in post-traumatic amnesia (PTA). Speech pathologists with experience of adults in PTA were invited to take part in an online survey through Australian professional email/internet-based interest groups. Forty-five speech pathologists responded to the online survey. The majority of respondents (78%) reported using informal, observational assessment methods commencing at initial contact with people in PTA or when patients' level of alertness allowed and initiating formal assessment on emergence from PTA. Seven respondents (19%) reported undertaking no assessment during PTA. Clinicians described using a range of techniques to monitor cognitive-communication during PTA, including static, dynamic, functional and impairment-based methods. The study confirmed that speech pathologists have a key role in the multidisciplinary team caring for the person in PTA, especially with family education and facilitating interactions with the rehabilitation team and family. Decision-making around timing and means of assessment of cognitive-communication during PTA appeared primarily reliant on speech pathologists' professional experience and the culture of their workplace. The findings support the need for further research into the nature of cognitive-communication disorder and resolution over this period.

Patient acceptance is one of the major barriers toward widespread use of mHealth systems. The aim of this study was to assess system operability and whole trial feasibility, including patients' experience with their use of COMMODITY12 mHealth system under. Secondary study aims included assessment of several metabolic parameters as well as patient adherence to the treatment. This was a prospective parallel-arm randomized controlled trial in outpatients diagnosed with DM2, being treated in the primary care settings in Lodz region, Poland, with 6 weeks period of follow-up. Patients opinions were collected with 7-item questionnaire, assessing different aspects of system use, as well as EuroQol-5D-5 L questionnaire, assessing health-related quality of life. Sixty patients (female, 24, male, 36, mean age +/- SD 59.5 +/- 6.8) completed study. All four layers of the COMMODITY12 system proved to work smooth under real-life conditions, without major problems. All dimensions of experience with system use were assessed well, with maximum values for clearness of instructions, and ease of use (4.80, and 4.63, respectively). Health related quality of life, as assessed with cumulative utility measure, improved significantly in COMMODITY12 system users (P < 0.05). mHealth system modestly improved glycaemic and blood pressure control, assuring high level of patient adherence with overall adherence reaching 92.9 %. Study proved that the COMODITY12 system is well accepted by type 2 diabetes patients taking part in clinical trial, leading to several clinical benefits, and improved quality of life. Nevertheless, before future commercialisation of the system, several minor problems identified during the study need to be addressed.

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

The New York University College of Dentistry has introduced a clinical rotation for fourth-year dental students that focuses on treating people with special health care needs (PSN). The aim of this study was to investigate the hypothesis that clinical experience in treating patients with special health care needs during predoctoral education is associated with increased self-assessed student ability and comfort and therefore self-efficacy. The study also investigated whether other characteristics, such as prior personal or volunteer experience with this population, service-mindedness, and/or the inclination to treat underserved populations, were associated with comfort in treating PSN. A survey was used to assess changes in students' perceived knowledge, beliefs, and attitudes regarding treating PSN before and after the clinical experience for July 2012-June 2013. The survey included questions about students' service-mindedness, comfort, perceptions of abilities of PSN and educational importance of learning to treat PSN, desire for clinical experience, and future intent or interest in treating PSN. Out of 364 students invited to participate, 127 surveys were returned, for a response rate of 34.9%. The results showed statistically significant increases on six items following training: impressions about the importance of oral health among PSN, comfort in treating people with cognitive disabilities and with medical complexities, intent to treat PSN in future practice, interest in including PSN in postgraduate training, and belief that PSN could be treated in the private practice setting. These students reported preferring to learn in the clinical setting over didactic instruction. This clinical experience was associated with improved self-efficacy in treating PSN and increased intentions to treat this population in future practice. Improvements were particularly evident among those with the least prior experience with PSN and were independent of other aspects of the students' past experience, future goals, or personality characteristics.

We evaluated 255 African (Loxodonta africana) and Asian (Elephas maximus) elephants living in 68 North American zoos over one year to quantify housing and social variables. All parameters were quantified for the both the day and the night and comparisons were made across these time periods as well as by species and sex. To assess housing, we evaluated not only total exhibit size, but also individual animals’ experiences based on the time they spent in the unique environments into which the exhibits were subdivided. Variables developed to assess housing included measurements of area as a function of time (Total Space Experience), environment type (Indoor, Outdoor, In/Out Choice) and time spent on hard and soft flooring. Over the year, Total Space Experience values ranged from 1,273 square feet to 169,692 square feet, with Day values significantly greater than Night values (p<0.001). Elephants spent an average of 55.1% of their time outdoors, 28.9% indoors, and 16% in areas with a choice between being in or out. Time spent on hard flooring substrate ranged from 0% to 66.7%, with Night values significantly greater than Day (p<0.001). Social factors included number of animals functionally housed together (Social Experience) and social group characteristics such as time spent with juveniles and in mixed-sex groups. Overall Social Experience scores ranged from 1 to 11.2 and were significantly greater during the Day than at Night (p<0.001). There were few significant social or housing differences between African (N = 138) and Asian (N = 117) species or between males (N = 54) and females (N = 201). The most notable exception was Total Space Experience, with African and male elephants having larger Total Space Experience than Asian and female elephants, respectively (P-value<0.05). The housing and social variables evaluated herein have been used in a series of subsequent epidemiological analyses relating to various elephant welfare outcomes. PMID:27414034

After the recent development of residential units for the execution of security measures managed by the National Health Service and the closing down of forensic psychiatric hospitals, no study has been conducted to investigate the individual experience of aging patients and to assess whether the new service is adequately meeting their needs. We aimed to explore the experience of the service of a sample of patients aged 50 years and above living in one of the Italian residential units for the execution of security measures. We adopted a case study design and included a sample of five patients. We collected their basic demographic data, administered the Camberwell Assessment Needs Forensic Short Version and carried out in-depth qualitative semi-structured interviews. Results from the Camberwell Assessment Needs Forensic Short Version evidenced that met needs were more prevalent than unmet needs. The qualitative interviews demonstrated high levels of satisfaction around accommodation, healthcare provision, activities, availability of benefits and company, and lower levels of satisfaction around psychological and practical support. This study gave voice to aging forensic psychiatric patients and provided through personal accounts, based on their lived experience, preliminary evidence around the benefits and limitations of the Italian residential forensic psychiatric system for this age group. Implications for clinical nursing forensic practitioners operating within different service frameworks are discussed.

There is increasing recognition of the need to identify risk factors for poor mental health in pregnancy and following birth. In New South Wales, Australia, health policy mandates psychosocial assessment and depression screening for all women at the antenatal booking visit and at six to eight weeks after birth. Few studies have explored in-depth women's experience of assessment and how disclosures of sensitive information are managed by midwives and nurses. This paper describes women's experience of psychosocial assessment and depression screening examining the meaning they attribute to assessment and how this influences their response. This qualitative ethnographic study included 34 women who were observed antenatally in the clinic with 18 midwives and 20 of the same women who were observed during their interaction with 13 child and family health nurses after birth in the home or the clinic environment. An observational tool, 4D&4R, together with field notes was used to record observations and were analysed descriptively using frequencies. Women also participated in face to face interviews. Field note and interview data was analysed thematically and similarities and differences across different time points were identified. Most participants reported that it was acceptable to them to be asked the psychosocial questions however they felt unprepared for the sensitive nature of the questions asked. Women with a history of trauma or loss were distressed by retelling their experiences. Five key themes emerged. Three themes; 'Unexpected: a bit out of the blue', 'Intrusive: very personal questions' and 'Uncomfortable: digging over that old ground', describe the impact that assessment had on women. Women also emphasised that the approach taken by the midwife or nurse during assessment influenced their experience and in some cases what they reported. This is reflected in the themes titled: 'sensitivity and care' and 'being watched'. The findings emphasise the need for health services to better prepare women for this assessment prior to and after birth. It is crucial that health professionals are educationally prepared for this work and receive ongoing training and support in order to always deliver care that is empathetic and sensitive to women who are disclosing personal information.

2018-01-01

Background: This study examined influences on the decisions of administrators of youth-serving organizations to initiate and proceed with implementation of an evidence-based practice (EBP). Methods: Semi-structured interviews, developed using the Stages of Implementation Completion (SIC) as a framework, were conducted with 19 agency chief executive officers and program directors of 15 organizations serving children and adolescents. Results: Agency leaders' self-assessments of implementation feasibility and desirability prior to implementation (Pre-implementation) were influenced by intervention affordability, feasibility, requirements, validity, reliability, relevance, cost savings, positive outcomes, and adequacy of information; availability of funding, support from sources external to the agency, and adequacy of technical assistance; and staff availability and attitudes toward innovation in general and EBPs in particular, organizational capacity, fit between the EBP and agency mission and capacity, prior experience with implementation, experience with seeking evidence, and developing consensus. Assessments during the Implementation phase included intervention flexibility and requirements; availability of funding, adequacy of training and technical assistance, and getting sufficient and appropriate referrals; and staffing and implementing with fidelity. Assessments during the Sustainment phase included intervention costs and benefits; availability of funding, support from sources outside of the agency, and need for the EBP; and the fit between the EBP and the agency mission. Discussion: The results point to opportunities for using agency leader models to develop strategies to facilitate implementation of evidence-based and innovative practices for children and adolescents. The SIC provides a standardized framework for guiding agency leader self-assessments of implementation.

Education in the ambulatory setting should be an integral part of undergraduate medical education. However, previous studies have shown education in this setting has been lacking in medical school. Ambulatory education occurs on some internal medicine clerkships. The extent of this education is unclear. The purpose of this survey was to assess the structure, curriculum, assessment methods, and barriers to implementation of ambulatory education on the internal medicine clerkship. An annual survey of institutional members of the Clerkship Directors in Internal Medicine (CDIM) was done in April 2010. The data were anonymous and descriptive statistics were used to summarize responses. Free text results were analyzed using qualitative techniques. The response rate was 75%. The majority of respondents had a required ambulatory component to the clerkship. Ambulatory experiences distinct from the inpatient internal medicine experience were common (46%). Integration with either the inpatient experiences or other departmental clerkships also occurred. The majority of ambulatory educational experiences were with generalists (74%) and/or subspecialists (45%). The most common assessment tool was the National Board of Medical Examiners (NBME) ambulatory shelf exam. Thematic analysis of the question about how practice based learning was taught elicited four major themes: Not taught; taught in the context of learning evidence based medicine; taught while learning chronic disease management with quality improvement; taught while learning about health care finance. Barriers to implementation included lack of faculty and financial resources. There have been significant increases in the amount of time dedicated to ambulatory internal medicine. The numbers of medical schools with ambulatory internal medicine education has increased. Integration of the ambulatory experiences with other clerkships such as family medicine occurs. Curriculum was varied but difficulties with dissemination and assessment in these disparate settings was noted. Overall, the results of this study demonstrate increased implementation and recognition of the importance of ambulatory education in internal medicine.

Piecewise exponential models to assess the influence of job-specific experience on the hazard of acute injury for hourly factory workers

PubMed Central

2013-01-01

Background An inverse relationship between experience and risk of injury has been observed in many occupations. Due to statistical challenges, however, it has been difficult to characterize the role of experience on the hazard of injury. In particular, because the time observed up to injury is equivalent to the amount of experience accumulated, the baseline hazard of injury becomes the main parameter of interest, excluding Cox proportional hazards models as applicable methods for consideration. Methods Using a data set of 81,301 hourly production workers of a global aluminum company at 207 US facilities, we compared competing parametric models for the baseline hazard to assess whether experience affected the hazard of injury at hire and after later job changes. Specific models considered included the exponential, Weibull, and two (a hypothesis-driven and a data-driven) two-piece exponential models to formally test the null hypothesis that experience does not impact the hazard of injury. Results We highlighted the advantages of our comparative approach and the interpretability of our selected model: a two-piece exponential model that allowed the baseline hazard of injury to change with experience. Our findings suggested a 30% increase in the hazard in the first year after job initiation and/or change. Conclusions Piecewise exponential models may be particularly useful in modeling risk of injury as a function of experience and have the additional benefit of interpretability over other similarly flexible models.

A study of flying quality requirements for air breathing aerospacecraft gives special emphasis to the unusual operational requirements and characteristics of these aircraft, including operation at hypersonic speed. The report considers distinguishing characteristics of these vehicles, including dynamic deficiencies and their implications for control. Particular emphasis is given to the interaction of the airframe and propulsion system, and the requirements for dynamic systems integration. Past operational missions are reviewed to define tasks and maneuvers to be considered for this class of aircraft. Areas of special concern with respect to vehicle dynamics and control are identified. Experience with the space shuttle orbiter is reviewed with respect to flight control system mechanization and flight experience in approach and landing flying qualities for the National Aerospace Plane (NASP).

The purpose of this study was to explore the experiences of Chinese parents of children diagnosed with acute lymphocytic leukemia (ALL). Respondents consisted of a convenience sample of nine mothers and eight fathers. Data were collected through in-depth interviews and were scheduled to coincide with the disease trajectory, and were analyzed using the matrix system described by Miles and Huberman. Major categories identified include parental reactions, methods used by the parents to disclose the child's diagnosis to others, changes in the family routine, and the preferred sources of parental support. Implications for health professionals include a need for thorough psychosocial assessment of the affected children, parents, and siblings. Limitations of the study and recommendations for future research are also discussed.

Dental caries is the most prevalent disease worldwide, with the majority of caries lesions being concentrated in few, often disadvantaged social groups. We aimed to systematically assess current evidence for the association between socioeconomic position (SEP) and caries. We included studies investigating the association between social position (determined by own or parental educational or occupational background, or income) and caries prevalence, experience, or incidence. Risk of bias was assessed using the Newcastle-Ottawa Scale for observational studies. Reported differences between the lowest and highest SEP were assessed and data not missing at random imputed. Random-effects inverse-generic meta-analyses were performed, and subgroup and meta-regression analyses were used to control for possible confounding. Publication bias was assessed via funnel plot analysis and the Egger test. From 5539 screened records, 155 studies with mostly low or moderate quality evaluating a total of 329,798 individuals were included. Studies used various designs, SEP measures, and outcome parameters. Eighty-three studies found at least one measure of caries to be significantly higher in low-SEP compared with high-SEP individuals, while only 3 studies found the opposite. The odds of having any caries lesions or caries experience (decayed missing filled teeth [DMFT]/dmft > 0) were significantly greater in those with low own or parental educational or occupational background or income (between odds ratio [95% confidence interval] = 1.21 [1.03-1.41] and 1.48 [1.34-1.63]. The association between low educational background and having DMFT/dmft > 0 was significantly increased in highly developed countries (R (2) = 1.32 [0.53-2.13]. Publication bias was present but did not significantly affect our estimates. Due to risk of bias in included studies, the available evidence was graded as low or very low. Low SEP is associated with a higher risk of having caries lesions or experience. This association might be stronger in developed countries. Established diagnostic and treatment concepts might not account for the unequal distribution of caries (registered with PROSPERO [CRD42013005947]). © International & American Associations for Dental Research 2014.

Study Design: Prospective survey-based study. Objectives: The AO Spine thoracolumbar injury classification has been shown to have good reproducibility among clinicians. However, the influence of spine surgeons’ clinical experience on fracture classification, stability assessment, and decision on management based on this classification has not been studied. Furthermore, the usefulness of varying imaging modalities including radiographs, computed tomography (CT) and magnetic resonance imaging (MRI) in the decision process was also studied. Methods: Forty-one spine surgeons from different regions, acquainted with the AOSpine classification system, were provided with 30 thoracolumbar fractures in a 3-step assessment: first radiographs, followed by CT and MRI. Surgeons classified the fracture, evaluated stability, chose management, and identified reasons for any changes. The surgeons were divided into 2 groups based on years of clinical experience as <10 years (n = 12) and >10 years (n = 29). Results: There were no significant differences between the 2 groups in correctly classifying A1, B2, and C type fractures. Surgeons with less experience had more correct diagnosis in classifying A3 (47.2% vs 38.5% in step 1, 73.6% vs 60.3% in step 2 and 77.8% vs 65.5% in step 3), A4 (16.7% vs 24.1% in step 1, 72.9% vs 57.8% in step 2 and 70.8% vs 56.0% in step3) and B1 injuries (31.9% vs 20.7% in step 1, 41.7% vs 36.8% in step 2 and 38.9% vs 33.9% in step 3). In the assessment of fracture stability and decision on treatment, the less and more experienced surgeons performed equally. The selection of a particular treatment plan varied in all subtypes except in A1 and C type injuries. Conclusion: Surgeons’ experience did not significantly affect overall fracture classification, evaluating stability and planning the treatment. Surgeons with less experience had a higher percentage of correct classification in A3 and A4 injuries. Despite variations between them in classification, the assessment of overall stability and management decisions were similar between the 2 groups. PMID:28815158

Prospective survey-based study. The AO Spine thoracolumbar injury classification has been shown to have good reproducibility among clinicians. However, the influence of spine surgeons' clinical experience on fracture classification, stability assessment, and decision on management based on this classification has not been studied. Furthermore, the usefulness of varying imaging modalities including radiographs, computed tomography (CT) and magnetic resonance imaging (MRI) in the decision process was also studied. Forty-one spine surgeons from different regions, acquainted with the AOSpine classification system, were provided with 30 thoracolumbar fractures in a 3-step assessment: first radiographs, followed by CT and MRI. Surgeons classified the fracture, evaluated stability, chose management, and identified reasons for any changes. The surgeons were divided into 2 groups based on years of clinical experience as <10 years (n = 12) and >10 years (n = 29). There were no significant differences between the 2 groups in correctly classifying A1, B2, and C type fractures. Surgeons with less experience had more correct diagnosis in classifying A3 (47.2% vs 38.5% in step 1, 73.6% vs 60.3% in step 2 and 77.8% vs 65.5% in step 3), A4 (16.7% vs 24.1% in step 1, 72.9% vs 57.8% in step 2 and 70.8% vs 56.0% in step3) and B1 injuries (31.9% vs 20.7% in step 1, 41.7% vs 36.8% in step 2 and 38.9% vs 33.9% in step 3). In the assessment of fracture stability and decision on treatment, the less and more experienced surgeons performed equally. The selection of a particular treatment plan varied in all subtypes except in A1 and C type injuries. Surgeons' experience did not significantly affect overall fracture classification, evaluating stability and planning the treatment.
