Objectives: To determine the impact of pharmacist-provided educational seminars on the participant’s perception of the pharmacist’s role in providing women’s health education. Secondary objectives include the participant’s level of perceived benefit from the information provided during each presentation, as well as determining characteristics of participants who are interested in attending seminars. Methods: This is a prospective study conducted within a homeless women’s shelter in Phoenix, Arizona. Pharmacists and pharmacy students provided 10 monthly educational seminars on topics related to women’s health. Participants completed a pre- and post-seminar survey regarding their perceptions of the presentations and pharmacists. Results: Fifty-six participants attended at least one of 10 seminars from January to November 2014. The average age was 46 years old, taking approximately 3 medications, and 66% completed a high school degree or lower. Prior to the presentations, 30% of participants agreed or strongly agreed that they would seek advice from a pharmacist on the topic presented, which increased significantly to 82% of participants after the presentation (p<0.001). Similarly, 55% of participants rated themselves as agreeing or strongly agreeing with being knowledgeable on the topic presented prior to the presentation, and this increased significantly to 77% after the presentation (p=0.001). After attending the educational session, 70% of participants agreed or strongly agreed that they would make changes to their health, and that they would attend an additional session. The participants noted their increased learning about the topic, the clarity of visual aids and presentation, and knowledge of the presenters as the best parts of the presentation. Conclusion: Pharmacist’s participation in providing educational seminars in the homeless women’s population increases the participant’s knowledge and perception of the pharmacist’s role within the population. Future studies can further investigate an evolving role of pharmacists in optimizing healthcare in the homeless population. PMID:26759620

Neef, N A; Trachtenberg, S; Loeb, J; Sterner, K

1991-01-01

We conducted two studies to evaluate a video-based instructional package for training respite care providers and the role of presentation format (viewing the videotapes alone, with a partner, and with structured group training) as a contextual variable. In Study 1, the results of a within-subjects Latin square design nested within a multiple baseline showed that performance during simulated (role-played) respite care situations improved in five of the six skill areas for the 12 trainees following presentation of the videotape, with no differences between presentation formats. Correct responding generalized to respite care situations involving a developmentally disabled child, and in most cases, acquired skills were maintained for up to 6 months. In Study 2, we conducted a clinical replication of Study 1 under conditions more closely approximating those in which the training program would be implemented by respite care agencies. Results of the between-groups analysis were consistent with the findings of Study 1. PMID:1836458

Visits to emergency departments for substance use/abuse are common worldwide. However, emergency department health care providers perceive substance-using patients as a challenging group to manage which can lead to negative attitudes. Providing education or experience-based exercises may impact positively on behaviors towards this patient population. Whether staff attitudes are similarly impacted by knowledge acquired through educational interventions remains unknown. To synthesize available evidence on the relationship between new knowledge gained through substance use educational interventions and emergency department health care providers' attitudes towards patients with substance-related presentations. Health care providers working in urban and rural emergency departments of healthcare facilities worldwide providing care to adult patients with substance-related presentations. Quantitative papers examining the impact of substance use educational interventions on health care providers' attitudes towards substance using patients. Experimental and non-experimental study designs. Emergency department staff attitudes towards patients presenting with substance use/abuse. A three-step search strategy was conducted in August 2015 with a search update in March 2017. Studies published since 1995 in English, French or Spanish were considered for inclusion. Two reviewers assessed studies for methodological quality using critical appraisal checklists from the Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI). Reviewers agreed on JBI-MAStARI methodological criteria a study must meet in order to be included in the review (e.g. appropriate use of statistical analysis). The data extraction instrument from JBI-MAStARI was used. As statistical pooling of the data was not possible, the findings are presented in narrative form. A total of 900 articles were identified as relevant for this review. Following abstract and full text screening, four articles were selected and assessed for methodological quality. One article met methodological criteria for inclusion in the review: use of random assignment and comparable study groups and measurement outcomes in a reliable and consistent manner. The included study was a cluster randomized controlled trial. Participants were emergency medicine residents with a mean age of 30 years. The study assessed the impact of a skills-based educational intervention on residents' attitudes, knowledge and practice towards patients with alcohol problems. While knowledge and practice behaviors improved one year following the intervention, there were no significant differences between groups on attitudinal measures. Employing educational interventions to improve the attitudes of emergency department staff towards individuals with drug and alcohol related presentations is not supported by evidence.

To analyze different ways of presenting medical information to older adults, tailoring the information and its presentation to the characteristics of memory function in old age. Experimental study. We took into account the following variables: amount of information, type of information and mode of presentation, and time delay. The greater the number of recommendations, the lower the recall; visual presentation does not enhance verbal presentation; lifestyle information is recalled better than medication information; after ten minutes the percentage of memory decreases significantly; the first and last recommendations are better remembered. As a whole, these findings show that older adults remember more medical information when very few recommendations are provided in each session. It is inadvisable to overload older adults with a large amount of information: It is better to program more consultations and provide less information. Copyright © 2016 Elsevier Ireland Ltd.

Structure and stability of clusters of β-alanine in the gas phase: importance of the nature of intermolecular interactions.

PubMed

Piekarski, Dariusz Grzegorz; Díaz-Tendero, Sergio

2017-02-15

We present a theoretical study of neutral clusters of β-alanine molecules in the gas phase, (β-ala) n n ≤ 5. Classical molecular dynamics simulations carried out with different internal excitation energies provide information on the clusters formation and their thermal decomposition limits. We also present an assessment study performed with different families of density functionals using the dimer, (β-ala) 2 , as a benchmark system. The M06-2X functional provides the best agreement in geometries and relative energies in comparison with the reference values computed with the MP2 and CCSD(T) methods. The structure, stability, dissociation energies and vertical ionization potentials of the studied clusters have been investigated using this functional in combination with the 6-311++G(d,p) basis set. An exhaustive analysis of intermolecular interactions is also presented. These results provide new insights into the stability, interaction nature and formation mechanisms of clusters of amino acids in the gas phase.

Geologic studies in Alaska by the U.S. Geological Survey, 1997

USGS Publications Warehouse

Kelley, Karen D.

1999-01-01

Geologic Framework studies provide background information that is the scientific basis for present and future studies of the environment, mineral and energy resources, paleoclimate, and hazards in Alaska. One paper presents the results of sedimentologic and paleontologic comparisons of lower Paleozoic, deep-water-facies rock units in central Alaska (Dumoulin and others). The authors show which of these units are likely to correlate with one another, suggest likely source regions, and provide a structural restoration of units that have been fragmented by large fault motions. A second framework paper provides a map, rock descriptions, and chemical compositions of volcanic rocks in a newly recognized, geologically young volcanic center in the Aleutian volcanic arc (Hildreth and others). A third paper presents an interesting summary of gravity changes that occurred in south-central Alaska during the great earthquake of 1964 and for the following 25 years (Barnes). Gravity changes correlate with land-elevation changes in some cases, but not in others, which means that different processes are responsible for the gravity changes.

Breast cancer patients are presenting at advanced stages for oncological treatment in Nigeria and World Health Organization predicted developing countries' breast cancer incidence and mortality to increase by year 2020. Prospective observational hospital based study that enrolled breast cancer patients from catchment area of an oncology service hospital in Nigeria between 2007 and 2013. Patients' demographics, breast cancer burden and health care giver presentation variables were analysed for causal factors of seeking medical help and what determines commencement of effective oncological treatment. Forty-six patients were enrolled, 19.6% of them presented primarily to oncologist while 80.4% presented secondarily for oncological treatment. There is a significant difference in presentation time for oncological treatment (t = -3.56, df = 42.90, p = 0.001) between primary (M =11.56 ± 5.21 weeks) and secondary presentation (M= 52.56 ± 10.27weeks). Tumor burden of those that presented secondarily were significantly more advanced (U = 78.5, p = 0.011) and, univariate analysis reveals that: patients' matrimonial setting, breast cancer awareness and mode of discovery of breast symptoms are patient related factors that determines their choice of health care providers and, determinant of effective oncological treatment is patient first contact health care provider. Patients' bio-characteristics that determine their choice of health care provider should be incorporated into community breast cancer sensitization drives. Additionally, there is a need for a government agency assign the task of accrediting and defining scope of enterprise of health care institutions and their health care providers in our pluralist health system.

Azh, Nezal; Ozgoli, Giti; Ardalan, Gelayol

2017-01-01

Introduction Providing health services for adolescents requires exploration of hidden factors from the perspective of adolescents, providers, and key individuals. Understanding the process of providing health services from adolescents point of view will help receiving and continuation of services. Although many studies have been conducted in Iran on adolescents health needs, few studies have dealt with provision of these services to adolescents. Aim The present study aimed to explain the adolescents and key informants’ perception of healthcare provision. Materials and Methods The present qualitative study was conducted according to grounded theory. Data were collected using deep semi-structured individual interviews and group discussion. Participants were selected through purposive sampling followed by theoretical sampling. Participants in present study were 65 adolescents, nine youths (19-24-year-old), and 19 parents and key people involved in providing health services. Adolescents and their parents were selected from different parts of Tehran. Data collection continued until data saturation, and was analysed using Corbin-Strauss (2008) method. Results Issues relating to adolescents perception of the process of providing services included health concerns, society’s inappropriate behaviours, and weakness of the health services system in responding to adolescents needs, which as underlying factors contributed to adolescents confusion in receiving services and their proper coping with puberty. Conclusion Due to lack of education on how to manage puberty by parents, schools, society, and the health system, participating adolescents from Tehran were confused about receiving information and unable to manage puberty problems. Solving this problem requires continuity of services and interaction of family, school and community. PMID:28658809

Empirical development of brief smoking prevention videotapes which target African-American adolescents.

PubMed

Sussman, S; Parker, V C; Lopes, C; Crippens, D L; Elder, P; Scholl, D

1995-07-01

Two studies are described which provide evaluations for two brief videotapes developed as supplemental materials in the prevention of tobacco use among African-American adolescents. One videotape (the "soap opera") provides a more general audience-oriented presentation of prevention material and it was filmed primarily at a shopping mall, whereas the other videotape (the "rap") provides a "hip-hop generation" presentation, and it was filmed primarily at an outdoor hangout. The first study compared the two videotapes against each other. The second study compared the two videotapes combined in the same presentation, controlling for order of presentation, against a discussion group control. The results of the two studies indicated few differences in receptivity to the two videotapes among primarily African-American and Latino young adolescents. The rap videotape was rated as more accurate in its depiction of the African-American lifestyle, although both videotapes were equally liked. When shown together, the videotapes were not found to be superior in decreasing behavioral intention to smoke compared to a discussion group control. No change in trial of smoking was observed within or across conditions measured over a pre-post summer interval. These data suggest that "culturally sensitive" videotapes have no more of a short-term effect on youth than do other types of brief interventions which involve minority implementers.

Stellar Rotation: New Insight from CoRoT

NASA Astrophysics Data System (ADS)

Catala, C.; Goupil, M. J.; Michel, E.; Baglin, A.; de Medeiros, J. Renan; Gondoin, Ph.

2009-02-01

We present an overview of the new insight provided by the CoRoT satellite on stellar rotation. Thanks to its ultra-high precision, high duty cycle, long photometric monitoring of thousands of stars, CoRoT gives us a powerful tool to study stellar rotational modulation, and therefore to measure stellar rotational periods and to study active structures at the surface of stars. This paper presents preliminary results concerning this type of study. CoRoT will also provide us with an insight of internal stellar rotation via the measurement and exploitation of rotational splittings of oscillation modes. This approach to stellar rotation with CoRoT will require a careful analysis of the oscillation power spectra, which is in progress, but prospects for such measurements are presented.

The chemical preparation of high purity potassium and barium ferrates for alkaline electrochemical storage are presented. The synthesized salts are used to demonstrate a variety of high capacity super-iron (Zn anode) alkaline AAA cell configurations which utilize these Fe(V) salts. Results of 500 days, full stability, of the synthesized K 2FeO 4 are presented. Synthetic pathways yielding 80-100 g of 96.5-99.5% pure K 2FeO 4 and BaFeO 4 are presented, and the products of these syntheses are demonstrated to provide a high energy electrochemical discharge in a variety of AAA alkaline cells. BaFeO 4 super-iron alkaline AAA cells provide over 0.8 W h during 2.8 Ω discharge, yielding over 200% higher capacity than conventional alkaline batteries. The barium super-iron cell configurations studied provide higher capacity than the potassium super-iron alkaline cell configurations studied.

Patients with acute aneurysmal subarachnoid hemorrhage (SAH) often present with more than just neurological compromise. A wide spectrum of complicating cardiopulmonary abnormalities have been documented in patients with acute SAH, presenting additional challenges to the healthcare providers who attempt to treat and stabilize these patients. The patients described in this article presented with both acute aneurysmal SAH and cardiopulmonary compromise. Education and further research on this connection is needed to provide optimal care and outcomes for this vulnerable population. Nurses play a key role in balancing the critical and diverse needs of patients presenting with these symptoms. PMID:18856247

Summary of papers presented at the 2012 seventh international cough symposium

PubMed Central

2013-01-01

Twenty six papers were presented as posters in the Seventh International Symposium on Cough; 12 papers were presented in the Basic Science of Cough session, and 14 papers presented in the Clinical Science of Cough session. These papers explored a wide spectrum of cough-related areas including pathophysiological mechanisms, treatment and detection of cough, and symptom assessment and perception, and were grouped into several general themes for facilitate the discussion. Studies presented in these posters have provided new information that should improve our knowledge on the basic physiology and pharmacology of cough, and the peripheral and central neural mechanisms involved in the generation of the cough motor pattern. In addition, in the clinical science section, studies reporting potential new anti-tussive agents and further characterisation of cough symptoms and perception have provided a base for the fruitful strategies for the development of novel anti-tussive therapies and cough management.

2003-06-01

The European Physical Activity Surveillance System (EUPASS) research project compared several physical activity (PA) measures (including the International Physical Activity Questionnaire (IPAQ)) in a time series survey in eight countries of the European Union. The present paper describes first results provided by the different instruments regarding PA participation, frequency and duration, both at the European and national levels. The purpose of the present study is to explore and compare the specific quality and usefulness of different indicators rather than to provide valid and reliable prevalence data. Thus, the main focus is on discussion of the methodological implications of the results presented. A time series survey based on computer-aided telephone interviewing (CATI) was carried out in eight European countries over a six-month period. The study provided for about 100 realised interviews per month in each country (i.e. approximately 600 per country). Descriptive statistical analysis was used to: (1) report IPAQ results on vigorous, moderate and light PA and sitting, as well as on the overall measure of calories expenditure (MET min-1), in the different countries; (2) compare these results with national PA indicators tested in EUPASS; and (3) compare IPAQ results with other European studies. First, the scores for the different PA categories as well as for the overall measure of calories expenditure provided by the IPAQ appeared rather high compared with previous studies and public health recommendations. Second, the different PA measurements used in EUPASS provided completely different results. For example, national indicators used in Germany and The Netherlands to date neither corresponded in absolute values (e.g. means of PA or sitting) nor correlated with the IPAQ in any significant way. Third, comparing EU countries, the ranking for vigorous, moderate and light activities by use of the IPAQ differed from that of other European studies. For example, in the present analysis, German respondents generally showed higher scores for PA than the Finns and the Dutch, while, in contrast, findings from other studies ranked Finland before The Netherlands and Germany. The present analysis highlights some methodological implications of the IPAQ instrument. Among other things, differences in overall scores for PA as well as in the ranking of nations between the present results using IPAQ and other measures and studies may partly be due to the concepts of PA behind the measurements. Further analysis should investigate if the range of PA-related categories provided by the IPAQ is fully appropriate to measure all relevant daily activities; it may also consider the public health implications of mixing up different contexts of PA (e.g. work, leisure-time, transportation) in the IPAQ short version.

Medicines information provided by pharmaceutical representatives: a comparative study in Australia and Malaysia

PubMed Central

2010-01-01

Background Pharmaceutical representatives provide medicines information on their promoted products to doctors. However, studies have shown that the quality of this information is often low. No study has assessed the medicines information provided by pharmaceutical representatives to doctors in Malaysia and no recent evidence in Australia is present. We aimed to compare the provision of medicines information by pharmaceutical representatives to doctors in Australia and Malaysia. Methods Following a pharmaceutical representative's visit, general practitioners in Australia and Malaysia who had agreed to participate, were asked to fill out a questionnaire on the main product and claims discussed during the encounter. The questionnaire focused on provision of product information including indications, adverse effects, precautions, contraindications and the provision of information on the Pharmaceutical Benefit Scheme (PBS) listings and restrictions (in Australia only). Descriptive statistics were produced. Chi-square analysis and clustered linear regression were used to assess differences in Australia and Malaysia. Results Significantly more approved product information sheets were provided in Malaysia (78%) than in Australia (53%) (P < 0.001). In both countries, general practitioners reported that indications (Australia, 90%, Malaysia, 93%) and dosages (Australia, 76%, Malaysia, 82%) were frequently provided by pharmaceutical representatives. Contraindications, precautions, drug interactions and adverse effects were often omitted in the presentations (range 25% - 41%). General practitioners in Australia and Malaysia indicated that in more than 90% of presentations, pharmaceutical representatives partly or fully answered their questions on contraindications, precautions, drug interactions and adverse effects. More general practitioners in Malaysia (85%) than in Australia (60%) reported that pharmaceutical representatives should have mentioned contraindications, precautions for use, drug interaction or adverse effects spontaneously (P < 0.001). In 48% of the Australian presentations, general practitioners reported the pharmaceutical representatives failed to mention information on PBS listings to general practitioners. Conclusions Information on indications and dosages were usually provided by pharmaceutical representatives in Australia and Malaysia. However, risk and harmful effects of medicines were often missing in their presentations. Effective control of medicines information provided by pharmaceutical representatives is needed.

The detailed study of arm ossicles, particularly the lateral arm plates, is providing valuable information in the elucidation of ophiuroid taxonomy. The present study describes in detail 16 species of brittle stars from Araçá Bay, Brazil. This information is used to construct the first interactive electronic key, providing a valuable resource for a broad range of researchers. Brittle stars families were divided into three groups based on their spatial distribution: i) infaunal species of intertidal and shallow subtidal belonging to Amphiuridae and Ophiactidae, ii) epizoic species belonging to Amphiuridae, Ophiactidae, and Ophiotrichidae and, iii) epifaunal species of the subtidal belonging to Ophiodermatidae and Hemieuryalidae. In the global context of recent revisions of ophiuroid taxonomy, the present work provides additional characters for use in future phylogenetic studies.

2011-07-01

The aim of the present study was to compare the benefit of monaural versus binaural ear-level frequency modulated (FM) fitting on speech perception in noise in children with normal hearing. Reception threshold for sentences (RTS) was measured in no-FM, monaural FM, and binaural FM conditions in 22 normally developing children with bilateral normal hearing, aged 8 to 9 years old. Data were gathered using the Pediatric Malay Hearing in Noise Test (P-MyHINT) with speech presented from front and multi-talker babble presented from 90°, 180°, 270° azimuths in a sound treated booth. The results revealed that the use of either monaural or binaural ear level FM receivers provided significantly better mean RTSs than the no-FM condition (P<0.001). However, binaural FM did not produce a significantly greater benefit in mean RTS than monaural fitting. The benefit of binaural over monaural FM varies across individuals; while binaural fitting provided better RTSs in about 50% of study subjects, there were those in whom binaural fitting resulted in either deterioration or no additional improvement compared to monaural FM fitting. The present study suggests that the use of monaural ear-level FM receivers in children with normal hearing might provide similar benefit as binaural use. Individual subjects' variations of binaural FM benefit over monaural FM suggests that the decision to employ monaural or binaural fitting should be individualized. It should be noted however, that the current study recruits typically developing normal hearing children. Future studies involving normal hearing children with high risk of having difficulty listening in noise is indicated to see if similar findings are obtained.

Clinical audits have emerged as a potential tool to summarize the clinical performance of healthcare over a specified period of time. However, the effectiveness of audit and feedback has shown inconsistent results and the impact of audit and feedback on clinical performance has not been evaluated for COPD exacerbations. In the present study, we analyzed the results of two consecutive nationwide clinical audits performed in Spain to evaluate both the in-hospital clinical care provided and the feedback strategy. The present study is an analysis of two clinical audits performed in Spain that evaluated the clinical care provided to COPD patients who were admitted to the hospital for a COPD exacerbation. The first audit was performed from November-December 2008. The feedback strategy consisted of personalized reports for each participant center, the presentation and discussion of the results at regional, national and international meetings and the creation of health-care quality standards for COPD. The second audit was part of a European study during January and February 2011. The impact of the feedback strategy was evaluated in term of clinical care provided and in-hospital survival. A total of 94 centers participated in the two audits, recruiting 8,143 admissions (audit 1∶3,493 and audit 2∶4,650). The initially provided clinical care was reasonably acceptable even though there was considerable variability. Several diagnostic and therapeutic procedures improved in the second audit. Although the differences were significant, the degree of improvement was small to moderate. We found no impact on in-hospital mortality. The present study describes COPD hospital care in Spanish hospitals and evaluates the impact of peer-benchmarked, individually written and group-oral feedback strategy on the clinical outcomes for treating COPD exacerbations. It describes small to moderate improvements in the clinical care provided to COPD patients with no impact on in-hospital mortality.

Exploring dynamics of abusive lesbian relationships: preliminary analysis of a multisite, qualitative study.

PubMed

Ristock, Janice L

2003-06-01

This paper presents preliminary results from a multisite, qualitative study on violence in lesbian relationships. A framework for conducting community-based, empowerment research that draws on theories of community psychology, feminism, and postmodernism is presented. The study was designed to understand the dynamics of abusive lesbian relationships and social service providers' responses to the abuse. Results from 80 in-depth interviews with lesbians who have experienced relationship violence are examined with a particular focus on a pattern of first relationships being abusive and a theme of shifting power dynamics. Analysis of focus group discussions with 45 feminist service providers (e.g., counselors, shelter workers, social workers, healthcare providers) reveals the difficulties in assessing the power dynamics of abusive same-sex relationships and in developing appropriate responses when relying on heterosexually gendered models developed to address men's violence against women. The preliminary results present implications both for how we theorize and research this form of violence, and for improving the practices and policies of social services that work with lesbian, gay, bisexual, and transgendered communities.

The first does the work, but the third time's the charm: the effects of massed repetition on episodic encoding of multimodal face-name associations.

PubMed

Mangels, Jennifer A; Manzi, Alberto; Summerfield, Christopher

2010-03-01

In social interactions, it is often necessary to rapidly encode the association between visually presented faces and auditorily presented names. The present study used event-related potentials to examine the neural correlates of associative encoding for multimodal face-name pairs. We assessed study-phase processes leading to high-confidence recognition of correct pairs (and consistent rejection of recombined foils) as compared to lower-confidence recognition of correct pairs (with inconsistent rejection of recombined foils) and recognition failures (misses). Both high- and low-confidence retrieval of face-name pairs were associated with study-phase activity suggestive of item-specific processing of the face (posterior inferior temporal negativity) and name (fronto-central negativity). However, only those pairs later retrieved with high confidence recruited a sustained centro-parietal positivity that an ancillary localizer task suggested may index an association-unique process. Additionally, we examined how these processes were influenced by massed repetition, a mnemonic strategy commonly employed in everyday situations to improve face-name memory. Differences in subsequent memory effects across repetitions suggested that associative encoding was strongest at the initial presentation, and thus, that the initial presentation has the greatest impact on memory formation. Yet, exploratory analyses suggested that the third presentation may have benefited later memory by providing an opportunity for extended processing of the name. Thus, although encoding of the initial presentation was critical for establishing a strong association, the extent to which processing was sustained across subsequent immediate (massed) presentations may provide additional encoding support that serves to differentiate face-name pairs from similar (recombined) pairs by providing additional encoding opportunities for the less dominant stimulus dimension (i.e., name).

2015-01-01

Breast cancer is the most common cancer among women in Malaysia. Therefore, it is highly important for the public to be educated on breast cancer and to know the steps to detect it early on. Healthcare providers are in the prime position to provide such education to the public due to their high knowledge regarding health and their roles in healthcare. The present systematic review involved studies conducted in recent years to analyze the knowledge, attitudes and behavior of Malaysian healthcare providers regarding breast cancer, in attempts to obtain an overall picture of how well equipped our healthcare providers are to provide optimal breast cancer education, and to see their perceptions and actual involvement in said education. The systematic review was conducted via a primary search of various databases and journal websites, and a secondary search of references used by eligible studies. Criteria for eligibility included being published from the year 2008 till present, being conducted in Malaysia, and being written in the English language. A total of two studies were eligible for this review. Findings show that Malaysian future and current healthcare providers have moderate knowledge on breast cancer, have a positive towards involvement of breast cancer education, but have poor actual involvement.

Testing an Attribution Model of Caregiving in a Latino Sample: The Roles of Familismo and the Caregiver-Care Recipient Relationship.

PubMed

Villalobos, Bianca T; Bridges, Ana J

2016-07-01

This study tests the parameters of Weiner's attribution model of caregiving, which describes how attributions of controllability relate to emotional reactions, which in turn influence willingness to provide support to stigmatized individuals. To date, the model has not been explored in the context of cultural variables, the caregiver-recipient relationship, or types of support. The present study examined the attribution model using a Latino community sample (N = 96) that was presented with vignettes describing an individual with depression. Support was found for the basic attribution model. Familismo was predictive of attributions of controllability and the basic model was predictive of emotional support, but not instrumental support. Participants were more willing to provide instrumental support to a partner, but had more positive affective reactions toward a sibling. The findings provide important information about contextual factors that may motivate Latino caregivers to provide support. © The Author(s) 2015.

Recognizing the clinical manifestations of acromegaly: case studies.

PubMed

Iuliano, Sherry L; Laws, Edward R

2014-03-01

To present case studies of a 36-year-old woman and a 73-year-old man who presented with the syndrome of acromegaly, and to provide primary care nurse practitioners (NPs) with the understanding of the clinical and laboratory features needed for early recognition and treatment of this fascinating disease. A comprehensive review of published literature on acromegaly is presented. The findings discussed include the history, physical examination, and diagnostic studies of two patients presenting in different ways. They both saw multiple healthcare providers, and had symptoms and signs eventually leading to the diagnosis of acromegaly. Acromegaly is the result of excessive amounts of growth hormone (GH) and insulin-like growth factor type 1 (IGF-1), almost always caused by a benign adenoma of the pituitary gland. This leads to coarse facial features, soft tissue swelling (including the tongue), enlargement of the hands and feet, respiratory problems, hypertension, diabetes mellitus, carpal tunnel syndrome, and osteoarthritis. Early recognition and appropriate referral can reverse some of the signs and symptoms over time, and lead to decreased mortality and a markedly improved quality of life. These cases exemplify the challenges faced by NPs and other healthcare providers in diagnosing patients with acromegaly. ©2013 The Author(s) ©2013 American Association of Nurse Practitioners.

Zwijnenberg, Nicolien C; Bloemendal, Evelien; Damman, Olga C; de Jong, Judith D; Delnoij, Diana MJ; Rademakers, Jany JD

Background The Internet is increasingly being used to provide patients with information about the quality of care of different health care providers. Although online comparative health care information is widely available internationally, and patients have been shown to be interested in this information, its effect on patients’ decision making is still limited. Objective This study aimed to explore patients’ preferences regarding information presentation and their values concerning tailored comparative health care information. Meeting patients’ information presentation needs might increase the perceived relevance and use of the information. Methods A total of 38 people participated in 4 focus groups. Comparative health care information about hip and knee replacement surgery was used as a case example. One part of the interview focused on patients’ information presentation preferences, whereas the other part focused on patients’ values of tailored information (ie, showing reviews of patients with comparable demographics). The qualitative data were transcribed verbatim and analyzed using the constant comparative method. Results The following themes were deduced from the transcripts: number of health care providers to be presented, order in which providers are presented, relevancy of tailoring patient reviews, and concerns about tailoring. Participants’ preferences differed concerning how many and in which order health care providers must be presented. Most participants had no interest in patient reviews that were shown for specific subgroups based on age, gender, or ethnicity. Concerns of tailoring were related to the representativeness of results and the complexity of information. A need for information about the medical specialist when choosing a hospital was stressed by several participants. Conclusions The preferences for how comparative health care information should be presented differ between people. “Information on demand” and information about the medical specialist might be promising ways to increase the relevancy and use of online comparative health care information. Future research should focus on how different groups of people use comparative health care information for different health care choices in real life. PMID:27895006

An explorative study of experiences of healthcare providers posing as simulated care receivers in a 'care-ethical' lab.

PubMed

Vanlaere, Linus; Timmermann, Madeleine; Stevens, Marleen; Gastmans, Chris

2012-01-01

In recent approaches to ethics, the personal involvement of health care providers and their empathy are perceived as important elements of an overall ethical ability. Experiential working methods are used in ethics education to foster, inter alia, empathy. In 2008, the care-ethics lab 'sTimul' was founded in Flanders, Belgium, to provide training that focuses on improving care providers' ethical abilities through experiential working simulations. The curriculum of sTimul focuses on empathy sessions, aimed at care providers' empathic skills. The present study provides better insight into how experiential learning specifically targets the empathic abilities of care providers. Providing contrasting experiences that affect the care providers' self-reflection seems a crucial element in this study. Further research is needed to provide more insight into how empathy leads to long-term changes in behaviour.

Seal Technology for Hypersonic Vehicle and Propulsion: An Overview

NASA Technical Reports Server (NTRS)

Steinetz, Bruce M.

2008-01-01

Hypersonic vehicles and propulsion systems pose an extraordinary challenge for structures and materials. Airframes and engines require lightweight, high-temperature materials and structural configurations that can withstand the extreme environment of hypersonic flight. Some of the challenges posed include very high temperatures, heating of the whole vehicle, steady-state and transient localized heating from shock waves, high aerodynamic loads, high fluctuating pressure loads, potential for severe flutter, vibration, and acoustic loads and erosion. Correspondingly high temperature seals are required to meet these aggressive requirements. This presentation reviews relevant seal technology for both heritage (e.g. Space Shuttle, X-15, and X-38) vehicles and presents several seal case studies aimed at providing lessons learned for future hypersonic vehicle seal development. This presentation also reviews seal technology developed for the National Aerospace Plane propulsion systems and presents several seal case studies aimed at providing lessons learned for future hypersonic propulsion seal development.

2011-10-01

The aim of the present study was to investigate the feasibility of using a store-and-forward Skin Emergency Telemedicine Service (SETS) to provide rapid specialist diagnostic and management advice for dermatological cases in an ED. This pilot study was conducted at the Princess Alexandra Hospital between August 2008 and August 2009. Study subjects were consenting patients over 18 years of age who presented with a dermatological condition to the ED. The ED doctor sent the patient's history, examination findings and the digital images of the skin conditions to a secure email address, which automatically forwarded this to the teledermatologist. The teledermatologist reviewed the cases and sent advice on diagnosis and management to the referring ED doctor via email and/or telephone. Face-to-face follow-up consultations with the patients were conducted within 2 weeks. The diagnostic and management concordance between ED doctors, teledermatologists and reviewing dermatologists were analysed. A total of 60 patients participated in the present study. SETS provided a rapid response with 56 (93%) of ED consultations receiving a dermatology opinion within 2 h. Face-to-face follow up occurred in 50 patients (83%). Statistical analysis showed significant levels of agreement between tele-diagnosis and ED diagnosis of 71.2% (Kappa 0.42) and tele-diagnosis and final clinical diagnosis of 98% (Kappa: 0.93). The clinical management concordance was 96% in complete agreement and 4% in relative agreement between the teledermatologists and reviewing dermatologists, based on chart review. The present study has shown that SETS can provide rapid and accurate diagnostic and treatment advice from a specialist for dermatological presentations to the ED. © 2011 The Authors.

Finding the breech: Influence of breech presentation on mode of delivery based on timing of diagnosis, attempt at external cephalic version, and provider success with version.

PubMed

Andrews, Suzanne; Leeman, Lawrence; Yonke, Nicole

2017-09-01

Breech presentation affects 3-4% of pregnancies at term and malpresentation is the primary indication for 10-15% of cesarean deliveries. External cephalic version is an effective intervention that can decrease the need for cesarean delivery; however, timely identification of breech presentation is required. We hypothesized that women with a fetus in a breech presentation that is diagnosed after 38 weeks' estimated gestational age have a decreased likelihood of external cephalic version attempted and an increased likelihood of cesarean delivery. This was a retrospective cohort study. A chart review was performed for 251 women with breech presentation at term presenting to our tertiary referral university hospital for external cephalic version, cesarean for breech presentation, or vaginal breech delivery. Vaginal delivery was significantly more likely (31.1% vs 12.5%; P<.01) in women with breech presentation diagnosed before 38 weeks' estimated gestational age as external cephalic version was offered, and subsequently attempted in a greater proportion of women diagnosed before 38 weeks. External cephalic version was more successful when performed by physicians with greater procedural volume during the 3.5 year period of the study (59.1% for providers performing at least 10 procedures vs 31.3% if performing fewer than 10 procedures, P<.01). Results support the need for interventions to increase timely diagnosis of breech presentation as well as improved patient counseling and use of experienced providers for external cephalic version. © 2017 Wiley Periodicals, Inc.

The impact of pediatric neuropsychological consultation in mild traumatic brain injury: a model for providing feedback after invalid performance.

PubMed

Connery, Amy K; Peterson, Robin L; Baker, David A; Kirkwood, Michael W

2016-05-01

In recent years, pediatric practitioners have increasingly recognized the importance of objectively measuring performance validity during clinical assessments. Yet, no studies have examined the impact of neuropsychological consultation when invalid performance has been identified in pediatric populations and little published guidance exists for clinical management. Here we provide a conceptual model for providing feedback after noncredible performance has been detected. In a pilot study, we examine caregiver satisfaction and postconcussive symptoms following provision of this feedback for patients seen through our concussion program. Participants (N = 70) were 8-17-year-olds with a history of mild traumatic brain injury who underwent an abbreviated neuropsychological evaluation between 2 and 12 months post-injury. We examined postconcussive symptom reduction and caregiver satisfaction after neuropsychological evaluation between groups of patients who were determined to have provided noncredible effort (n = 9) and those for whom no validity concerns were present (n = 61). We found similarly high levels of caregiver satisfaction between groups and greater reduction in self-reported symptoms after feedback was provided using the model with children with noncredible presentations compared to those with credible presentations. The current study lends preliminary support to the idea that the identification and communication of invalid performance can be a beneficial clinical intervention that promotes high levels of caregiver satisfaction and a reduction in self-reported and caregiver-reported symptoms.

Steps toward a CONUS-wide reanalysis with archived NEXRAD data using National Mosaic and Multisensor Quantitative Precipitation Estimation (NMQ/Q2) algorithms

NASA Astrophysics Data System (ADS)

Stevens, S. E.; Nelson, B. R.; Langston, C.; Qi, Y.

2012-12-01

The National Mosaic and Multisensor QPE (NMQ/Q2) software suite, developed at NOAA's National Severe Storms Laboratory (NSSL) in Norman, OK, addresses a large deficiency in the resolution of currently archived precipitation datasets. Current standards, both radar- and satellite-based, provide for nationwide precipitation data with a spatial resolution of up to 4-5 km, with a temporal resolution as fine as one hour. Efforts are ongoing to process archived NEXRAD data for the period of record (1996 - present), producing a continuous dataset providing precipitation data at a spatial resolution of 1 km, on a timescale of only five minutes. In addition, radar-derived precipitation data are adjusted hourly using a wide variety of automated gauge networks spanning the United States. Applications for such a product range widely, from emergency management and flash flood guidance, to hydrological studies and drought monitoring. Results are presented from a subset of the NEXRAD dataset, providing basic statistics on the distribution of rainrates, relative frequency of precipitation types, and several other variables which demonstrate the variety of output provided by the software. Precipitation data from select case studies are also presented to highlight the increased resolution provided by this reanalysis and the possibilities that arise from the availability of data on such fine scales. A previously completed pilot project and steps toward a nationwide implementation are presented along with proposed strategies for managing and processing such a large dataset. Reprocessing efforts span several institutions in both North Carolina and Oklahoma, and data/software coordination are key in producing a homogeneous record of precipitation to be archived alongside NOAA's other Climate Data Records. Methods are presented for utilizing supercomputing capability in expediting processing, to allow for the iterative nature of a reanalysis effort.

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

This study aims to elucidate relations between provider perceptions of aspects of the consolidated framework for implementation research (Damschroder et al., 2009) and provider attitudes toward the implementation of evidence-based treatments (EBTs) in an ethnically diverse community health setting. Guided by directed content analysis, we analyzed 28 semistructured interviews that were conducted with providers during the pre-implementation phase of a larger implementation study for cognitive processing therapy for posttraumatic stress disorder (Resick et al., 2008). Our findings extend the existing literature by also presenting provider-identified client-level factors that contribute to providers' positive and negative attitudes toward EBTs. Provider-identified client-level factors include the following: client motivation to engage in treatment, client openness to EBTs, support networks of family and friends, client use of community and government resources, the connection and relationship with their therapist, client treatment adherence, client immediate needs or crises, low literacy or illiteracy, low levels of education, client cognitive limitations, and misconceptions about therapy. These results highlight the relations between provider perceptions of their clients, provider engagement in EBT training, and subsequent adoption of EBTs. We present suggestions for future implementation research in this area. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

2014-12-01

In the present article, we introduce the quadratic vagal activity-prosociality hypothesis, a theoretical framework for understanding the vagus nerve's involvement in prosociality. We argue that vagus nerve activity supports prosocial behavior by regulating physiological systems that enable emotional expression, empathy for others' mental and emotional states, the regulation of one's own distress, and the experience of positive emotions. However, we contend that extremely high levels of vagal activity can be detrimental to prosociality. We present 3 studies providing support for our model, finding consistent evidence of a quadratic relationship between respiratory sinus arrhythmia--the degree to which the vagus nerve modulates the heart rate--and prosociality. Individual differences in vagal activity were quadratically related to prosocial traits (Study 1), prosocial emotions (Study 2), and outside ratings of prosociality by complete strangers (Study 3). Thus, too much or too little vagal activity appears to be detrimental to prosociality. The present article provides the 1st theoretical and empirical account of the nonlinear relationship between vagal activity and prosociality.

Using Toulmin analysis to analyse an instructor's proof presentation in abstract algebra

NASA Astrophysics Data System (ADS)

Fukawa-connelly, Timothy

2014-01-01

This paper provides a method for analysing undergraduate teaching of proof-based courses using Toulmin's model (1969) of argumentation. It presents a case study of one instructor's presentation of proofs. The analysis shows that the instructor presents different levels of detail in different proofs; thus, the students have an inconsistent set of written models for their work. Similarly, the analysis shows that the details the instructor says aloud differ from what she writes down. Although her verbal commentary provides additional detail and appears to have pedagogical value, for instance, by modelling thinking that supports proof writing, this value might be better realized if she were to change her teaching practices.

Objective To develop methods to reliably capture structural and dynamic temporal features of clinical interactions. Methods Observational study of 50 audio-recorded routine outpatient visits to HIV specialty clinics, using innovative analytic methods. The Comprehensive Analysis of the Structure of Encounters System (CASES) uses transcripts coded for speech acts, then imposes larger-scale structural elements: threads – the problems or issues addressed; and processes within threads –basic tasks of clinical care labeled Presentation, Information, Resolution (decision making) and Engagement (interpersonal exchange). Threads are also coded for the nature of resolution. Results 61% of utterances are in presentation processes. Provider verbal dominance is greatest in information and resolution processes, which also contain a high proportion of provider directives. About half of threads result in no action or decision. Information flows predominantly from patient to provider in presentation processes, and from provider to patient in information processes. Engagement is rare. Conclusions In this data, resolution is provider centered; more time for patient participation in resolution, or interpersonal engagement, would have to come from presentation. Practice Implications Awareness of the use of time in clinical encounters, and the interaction processes associated with various tasks, may help make clinical communication more efficient and effective.

Manned Mars System Study (MMSS): Mars transportation and facility infrastructure study. Volume 2: Technical report

NASA Technical Reports Server (NTRS)

1990-01-01

The Manned Mars System Study (MMSS) was conducted for the Marshall Space Flight Center (MSFC) over the 35 month period between May 15, 1987 and April 30, 1990. During the course of the study, the NASA Office of Exploration (OEXP; Code Z) was created and MSFC was subsequently designated the Transportation Integration Agent (TIA) for support of the OEXP Mission Analysis and Systems Engineering (MASE) team. As a result of this action, modifications to the contract redirected the efforts to be consistent with NASA's overall objectives, including lunar transportation system design. A large number of written submittals were required in order to provide TIA support to MASE. A list summarizing the documents which have been prepared and delivered by Martin Marietta under this contract during the course of this work is presented. In nearly all cases, full sets of view-graphs were also provided to the MSFC COTR, and in several cases magnetic media were provided as well. To incorporate all of these materials (more than 2,000 pages) into the present report would obviously produce an extremely unwieldy and confusing document. Therefore, a summary of key findings are presented in this final report, supplemented by other material produced under this contract but not already available in the widespread literature.

Benchmarking Controlled Trial—a novel concept covering all observational effectiveness studies

PubMed Central

Malmivaara, Antti

2015-01-01

Abstract The Benchmarking Controlled Trial (BCT) is a novel concept which covers all observational studies aiming to assess effectiveness. BCTs provide evidence of the comparative effectiveness between health service providers, and of effectiveness due to particular features of the health and social care systems. BCTs complement randomized controlled trials (RCTs) as the sources of evidence on effectiveness. This paper presents a definition of the BCT; compares the position of BCTs in assessing effectiveness with that of RCTs; presents a checklist for assessing methodological validity of a BCT; and pilot-tests the checklist with BCTs published recently in the leading medical journals.

2008-10-01

The Indian subcontinent is characterized by the ancestral and cultural diversity of its people. Genetic input from several unique source populations and from the unique social architecture provided by the caste system has shaped the current genetic landscape of India. In the present study 200 individuals each from three upper-caste and four middle-caste Hindu groups and from two Muslim populations in North India were examined for 10 polymorphic Alu insertions (PAIs). The investigated PAIs exhibit high levels of polymorphism and average heterozygosity. Limited interpopulation variance and genetic flow in the present study suggest admixture. The results of this study demonstrate that, contrary to common belief, the caste system has not provided an impermeable barrier to genetic exchange among Indian groups.

2016-05-01

Disparities in health care associated with patients' gender, race, and age are well documented. Previous studies using virtual human (VH) technology have demonstrated that provider characteristics may play an important role in pain management decisions. However, these studies have largely emphasized group differences. The aims of this study were to examine dentists' and physicians' use of VH characteristics when making clinical judgments (i.e., cue use) and to identify provider characteristics associated with the magnitude of the impact of these cues (β-weights). Providers (N=152; 76 physicians, 76 dentists) viewed video vignettes of VH patients varying in gender (male/female), race (white/black), and age (younger/older). Participants rated VH patients' pain intensity and unpleasantness and then rated their own likelihood of administering non-opioid and opioid analgesics. Compared to physicians, dentists had significantly lower β-weights associated with VH age cues for all ratings (p<0.001; d>0.69). These effects varied by provider race and gender. For pain intensity, professional differences were present only among non-white providers. White providers had greater β-weights than non-white providers for pain unpleasantness but only among men. Provider differences regarding the use of VH age cues in non-opioid analgesic administration were present among all providers except non-white males. These findings highlight the interaction of patient and provider factors in driving clinical decision making. Although profession was related to use of VH age cues in pain-related clinical judgments, this relationship was modified by providers' personal characteristics. Additional research is needed to understand what aspects of professional training or practice may account for differences between physicians and dentists and what forms of continuing education may help to mitigate the disparities.

2013-08-01

To present a case study of a 34-year-old woman with Cushing's disease and provide nurse practitioners (NPs) with the understanding of the clinical presentation needed for early recognition and treatment of the disease. A comprehensive review of published literature on Cushing's disease. Findings from history, physical examination, and diagnostic studies of a woman presenting to primary care NPs, physicians and other healthcare providers with multiple symptoms of Cushing's disease. Cushing's disease is the result of the pituitary gland producing excess amounts of adrenocorticotropic hormone (ACTH) causing the overproduction of cortisol. The disease is fairly rare and is seen mostly in women. Common chief complaints include increased facial hair, weight gain, amenorrhea, changes in the face, neck, and abdomen, with muscle wasting of the lower extremities. Untreated, diabetes mellitus and hypertension can occur and increase the patient's morbidity and mortality. Early recognition and appropriate referral can reverse the signs and symptoms over time and lead to a significantly improved quality of life. This case presented the challenges faced by NPs and physicians in diagnosing patients with Cushing's disease. ©2013 The Author(s) ©2013 American Association of Nurse Practitioners.

Maternal Depressive Symptomatology and Child Behavior: Transactional Relationship with Simultaneous Bidirectional Coupling

PubMed Central

Nicholson, Jody S.; Deboeck, Pascal; Farris, Jaelyn R.; Boker, Steven M.; Borkowski, John G.

2011-01-01

The present study investigated reciprocal relationships between adolescent mothers and their children’s well-being through an analysis of the coupling relationship of mothers’ depressive symptomatology and children’s internalizing and externalizing behaviors. Unlike studies using discrete time analyses, the present study used dynamical systems to model time continuously, which allowed for the study of dynamic, transactional effects between members of each dyad. Findings provided evidence of coupling between maternal depressive symptoms and children’s behaviors. The most robust finding was that as maternal depressive symptoms became more or less severe, children’s behavior problems increased or decreased in a reciprocal manner. Results from this study extended upon theoretical contributions of authors such as Richters (1997) and Granic and Hollenstein (2003), providing empirical validation from a longitudinal study for understanding the ongoing, dynamic relationships between at-risk mothers and their children.

Stiffness Characteristics of Composite Rotor Blades With Elastic Couplings

NASA Technical Reports Server (NTRS)

Piatak, David J.; Nixon, Mark W.; Kosmatka, John B.

1997-01-01

Recent studies on rotor aeroelastic response and stability have shown the beneficial effects of incorporating elastic couplings in composite rotor blades. However, none of these studies have clearly identified elastic coupling limits and the effects of elastic couplings on classical beam stiffnesses of representative rotor blades. Knowledge of these limits and effects would greatly enhance future aeroelastic studies involving composite rotor blades. The present study addresses these voids and provides a preliminary design database for investigators who may wish to study the effects of elastic couplings on representative blade designs. The results of the present study should provide a basis for estimating the potential benefits associated with incorporating elastic couplings without the need for first designing a blade cross section and then performing a cross-section analysis to obtain the required beam section properties as is customary in the usual one-dimensional beam-type approach.

Control-Structure-Interaction (CSI) technologies and trends to future NASA missions

NASA Technical Reports Server (NTRS)

1990-01-01

Control-structure-interaction (CSI) issues which are relevant for future NASA missions are reviewed. This goal was achieved by: (1) reviewing large space structures (LSS) technologies to provide a background and survey of the current state of the art (SOA); (2) analytically studying a focus mission to identify opportunities where CSI technology may be applied to enhance or enable future NASA spacecraft; and (3) expanding a portion of the focus mission, the large antenna, to provide in-depth trade studies, scaling laws, and methodologies which may be applied to other NASA missions. Several sections are presented. Section 1 defines CSI issues and presents an overview of the relevant modeling and control issues for LLS. Section 2 presents the results of the three phases of the CSI study. Section 2.1 gives the results of a CSI study conducted with the Geostationary Platform (Geoplat) as the focus mission. Section 2.2 contains an overview of the CSI control design methodology available in the technical community. Included is a survey of the CSI ground-based experiments which were conducted to verify theoretical performance predictions. Section 2.3 presents and demonstrates a new CSI scaling law methodology for assessing potential CSI with large antenna systems.

Determinants of late presentation for induced abortion care.

PubMed

Waddington, Ashley; Hahn, Philip M; Reid, Robert

2015-01-01

To determine whether demographic or patient factors contribute to later presentation (10 to 12 weeks' gestational age) for induced abortion in a Canadian abortion clinic. Women attending a hospital-based abortion clinic between April and September 2012 were asked to complete a survey. The characteristics of women who presented early (EPs; gestational age < 10 weeks) were compared with those of late presenters (LPs; gestational age ≥ 10 weeks) using t tests for means and Fisher exact tests for rates. Among women referred to the clinic by a primary care provider, LPs were more likely than EPs to report "a delay in obtaining a referral" (20.8% vs. 6.1%; P = 0.007). While there was no significant difference between the groups in reporting that "someone tried to discourage [them] from having an abortion" (26.45% for EPs, 32.4% for LPs; P = 0.421), LPs were more likely to report that discouragement "caused a delay in making arrangements" (45.5% vs. 16.7%; P = 0.019). Of women who had access to a primary care provider, it was more common for the primary care provider to be aware of the pregnancy among LPs than among EPs (80.6% vs. 63.1%; P = 0.015). Some women delay presenting for abortion because of discouragement from friends and family. It is unclear whether there are educational or policy interventions that can have an impact on this delay, and this warrants further study. There may be ways of addressing the delay in referral by primary care providers. Further study into the causes for delay in referral for abortion is warranted.

Economic Valuation of Ecosystem Goods and Services in a Melting Arctic

NASA Astrophysics Data System (ADS)

O'Garra, T.

2014-12-01

The Arctic region is composed of unique ecosystems that provide a range of goods and services to local and global populations. However, Arctic sea-ice is melting at an unprecedented rate, threatening many of these ecosystems and the services they provide. Yet as the ice melts and certain goods and services are lost, other resources such as oil and minerals will become accessible. The question is: how do the losses compare with the opportunities? And how are the losses and potential gains likely to be distributed? To address these questions, this study provides a preliminary assessment of the quantity, distribution and economic value of the ecosystem services (ES) provided by Arctic ecosystems, both now and in the future given a scenario of sure climate change. Using biophysical and economic data from existing studies (and some primary data), preliminary estimates indicate that the Arctic currently provides 357m/yr (in 2014 US) in subsistence hunting value to local communities, of which reindeer/caribou comprise 83%. Reindeer herding provides 110m/yr to Arctic communities. Interestingly, 'non-use (existence/cultural) values' associated with Arctic species are very high at 11bn/yr to members of Arctic states. The Arctic also provides ES that accrue to the global community: oil resources (North Slope; 5bn profits in 2013), commercial fisheries ( 515mn/yr) and most importantly, climate regulation services. Recent models (Whiteman; Euskirchen) estimate that the loss of climate regulation services provided by Arctic ice will cost 200 - 500bn/yr, a value which dwarfs all others. Assuming no change in atmospheric temperature compared to 2014, the net present value of the Arctic by 2050 (1.4% discount rate) comes to over $9 trillion. However, given Wang and Overland (2009) predictions of ice-free summers by 2037, we expect many of these benefits will be lost. For example, it is fairly well-established that endemic species, such as polar bears, will decline with sea-ice melt. Estimation of such losses is ongoing for the present study. Increased opportunities include oil and mineral extraction, and increased shipping. The economic values associated with these potential opportunities (including environmental and social costs) are currently being assessed for the present study.

Provider communication about HPV vaccination: A systematic review

PubMed Central

Gilkey, Melissa B.; McRee, Annie-Laurie

2016-01-01

abstract Background. Improving HPV vaccination coverage in the US will require healthcare providers to recommend the vaccine more effectively. To inform quality improvement efforts, we systematically reviewed studies of provider communication about HPV vaccination. Methods. We searched MEDLINE, CINAHL, EMBASE, and POPLINE in August 2015 to identify studies of provider communication about HPV vaccination. Results. We identified 101 qualitative and quantitative studies. Providers less often recommended HPV vaccine if they were uncomfortable discussing sex, perceived parents as hesitant, or believed patients to be low risk. Patients less often received recommendations if they were younger, male, or from racial/ethnic minorities. Despite parents' preference for unambiguous recommendations, providers often sent mixed messages by failing to endorse HPV vaccine strongly, differentiating it from other vaccines, and presenting it as an “optional” vaccine that could be delayed. Conclusion. Interventions are needed to help providers deliver effective recommendations in the complex communication environment surrounding HPV vaccination. PMID:26838681

In recent years, built-operate-transfer (BOT) projects have profoundly been accepted under project financing for infrastructure developments in many countries. It requires high financing and involves complex mutual risk. The assessment of the risks is vital to avert huge financial loss. Net present value is widely applied to BOT project where the uncertainties in cash flows are deemed to be deterministic values. This study proposed a fuzzy net present value model taking consideration the assessment of risks from the BOT project. The proposed model is adopted to provide more flexible net present valuation of the project. It is shown and proven that the improved fuzzy cash flow model will provide a valuation that is closed to the real value of the project.

The resuscitation principles of securing the airway and stabilizing hemodynamics remain the same in any neonatal emergency. However, stabilizing endocrine disorders may prove especially challenging. Several organ systems are affected simultaneously and the clinical presentation can be subtle. Although not all-inclusive, the implementation of newborn screening tests has significantly reduced morbidity and mortality in neonates. Implementing routine screening tests worldwide and improving the accuracy of present tests remains the challenge for healthcare providers. With further study of these disorders and best treatment practices we can provide neonates presenting to the emergency department with the best possible outcomes. Copyright © 2014 Elsevier Inc.

2013-07-01

Job satisfaction is determined by a discrepancy between what one wants in a job and what one has in a job. The core components of information necessary for what satisfies and motivates the health work force in our country are missing at policy level. Therefore present study will help us to know the factors for job satisfaction among primary health care providers in public sector. Present study is descriptive in nature conducted in public sector dispensaries/primary urban health centers in Delhi among health care providers. Pretested structured questionnaire was administered to 227 health care providers. Data was analyzed using SPSS and relevant statistical test were applied. Analysis of study reveals that ANMs are more satisfied than MOs, Pharmacist and Lab assistants/Lab technicians; and the difference is significant (P < 0.01). Age and education level of health care providers don't show any significant difference in job satisfaction. All the health care providers are dissatisfied from the training policies and practices, salaries and opportunities for career growth in the organization. Majority of variables studied for job satisfaction have low scores. Five factor were identified concerned with job satisfaction in factor analysis. Job satisfaction is poor for all the four groups of health care providers in dispensaries/primary urban health centers and it is not possible to assign a single factor as a sole determinant of dissatisfaction in the job. Therefore it is recommended that appropriate changes are required at the policy as well as at the dispensary/PUHC level to keep the health work force motivated under public sector in Delhi.

This qualitative study was guided by Rogers' Theory of Diffusion of Innovations [NY: Free Press; 1995], and involved focus group and individual interviews of service providers (n = 31) and family caregivers (n = 4). Interview transcriptions were analyzed using descriptive, topic, and analytic coding, followed by thematic analysis. The network was identified as presenting an opportunity to fill communication gaps presented by other modes of communication and further enhance engagement with families. Barriers included time limitations and policy-related restrictions, privacy, security, and information ownership. Online networks may help address longstanding home-care issues around communication and information-sharing. The success of online networks in home care requires support from care partners. Future research should pilot the use of online networks in home care using barrier and facilitator considerations from this study.

The Electron Diffusion Region: Forces and Currents

NASA Technical Reports Server (NTRS)

Hesse, Michael

2008-01-01

The dissipation mechanism of magnetic reconnection remains a subject of intense scientific interest. On one hand, one set of recent studies have shown that particle inertia-based processes, which include thermal and bulk inertial effects, provide the reconnection electric field in the diffusion region. On the other hand, a second set of studies emphasizes the role of wave-particle interactions in providing anomalous resistivity in the diffusion region. In this presentation, we present analytical theory results, as well as PIC simulations of guide-field magnetic reconnection. We will show that the thermal electron inertia-based dissipation mechanism, expressed through nongyrotropic electron pressure tensors, remains viable in three dimensions. We will demonstrate the thermal inertia effect through studies of electron distribution functions. Furthermore, we will show that the reconnection electric field provides a transient acceleration on particles traversing the inner reconnection region. This inertia1 effect can be described as a diffusion-like term of the current density, which matches key features of electron distribution functions.

2017-05-01

To provide a brief presentation of preliminary data on rehabilitation services provided by clinical neuropsychologists within the United States. This survey utilized data extracted from a larger international research study conducted in 39 countries including N = 173 professionals who reported to engage in neuropsychological rehabilitative services within the past year (63.6% female, 44.36 ± 11.83 years of age) took part in the study. Neuropsychologists providing rehabilitation services in the United States in the past year were more likely to provide individual versus group therapy, likely to employ technology (e.g., personal computers, mobile phones/smartphones) as part of treatment services, see a range of diagnostic groups most prominently traumatic brain injury and stroke/vascular conditions, and work to address a range of both cognitive (e.g., memory, attention/concentration, and executive functioning) and psychological (e.g., emotional/behavioral adjustment and well-being, awareness of disability/disease) issues. Prior published surveys suggest that clinical neuropsychologists have a growing involvement in rehabilitation services within the United States but with little clarity as to the actual characteristics of actual professional activities and practices. The present study aimed to provide such information and hopefully will be helpful in promoting additional systematic studies in this area. © The Author 2017. Published by Oxford University Press.

The Internet is increasingly being used to provide patients with information about the quality of care of different health care providers. Although online comparative health care information is widely available internationally, and patients have been shown to be interested in this information, its effect on patients' decision making is still limited. This study aimed to explore patients' preferences regarding information presentation and their values concerning tailored comparative health care information. Meeting patients' information presentation needs might increase the perceived relevance and use of the information. A total of 38 people participated in 4 focus groups. Comparative health care information about hip and knee replacement surgery was used as a case example. One part of the interview focused on patients' information presentation preferences, whereas the other part focused on patients' values of tailored information (ie, showing reviews of patients with comparable demographics). The qualitative data were transcribed verbatim and analyzed using the constant comparative method. The following themes were deduced from the transcripts: number of health care providers to be presented, order in which providers are presented, relevancy of tailoring patient reviews, and concerns about tailoring. Participants' preferences differed concerning how many and in which order health care providers must be presented. Most participants had no interest in patient reviews that were shown for specific subgroups based on age, gender, or ethnicity. Concerns of tailoring were related to the representativeness of results and the complexity of information. A need for information about the medical specialist when choosing a hospital was stressed by several participants. The preferences for how comparative health care information should be presented differ between people. "Information on demand" and information about the medical specialist might be promising ways to increase the relevancy and use of online comparative health care information. Future research should focus on how different groups of people use comparative health care information for different health care choices in real life. ©Nicolien C Zwijnenberg, Michelle Hendriks, Evelien Bloemendal, Olga C Damman, Judith D de Jong, Diana MJ Delnoij, Jany JD Rademakers.

2014-11-01

This study determined the percentage of presentations at the annual conference of the Association for Behavior Analysis in 2005 with the autism (AUT) and developmental disabilities (DDA) codes (N=880) that (a) provided continuing education credits (CEs) for Board Certified Behavior Analysts (BCBAs) and Board Certified Assistant Behavior Analysts (BCaBAs) and (b) included content that was published in a peer-reviewed outlet. Results indicate that only 77 (8.8%) presentations were ultimately published. Although posters were not eligible for CEs, posters accounted for 57.1% of the published presentations. Specifically, posters presented by a university-affiliated presenter accounted for 44.2% of presentations with published content. As a whole, only 10.4% of AUT and DDA presentations offering CEs contained data sets that were published. Considered together, these results suggest that the content provided to BCBAs and BCaBAs for CEs may not be adequately measured or sufficiently rigorous to guide clinical practices.

Selecting healthcare information systems provided by third-party vendors: a mind map beyond the manuals.

PubMed

Gortzis, Lefteris G

2010-01-01

The selection of a new healthcare information system (HIS) has always been a daunting process for clinicians, health care providers and policy makers. The objective of this study is to present the lessons learned and the main findings from several relevant case studies to support this process. Data were collected by retrospectively reviewing the summative results of three well-established systems, acquiring feedback from two E.U. projects, and conducting semi-structured interviews with a number of collaborators involved in electronic healthcare interventions. Selection issues were identified and classified into the following five categories: (i) data creation, (ii) data management, (iii) data sharing, (iv) data presentation and (v) modules management. A mind map was also structured to provide a more manageable list of issues concerning the most common electronic clinical technologies (e-CT). The vendor manual is intended as an overview of the merchandise e-CT and therefore has limited potential in supporting effectively the selection process of a new HIS. The present classification and the mind map - based on lessons learned - provide a ready-to-use toolkit for supporting the HIS selection process when healthcare organisations are unable to employ research development groups to lay the groundwork for building a new HIS from scratch.

Andrews, R M; Curbow, B A; Owen, E; Burke, A

1989-01-01

Marketing strategies are critical for enhancing HMO enrollments among Medicaid beneficiaries when they are provided a choice of health plans. This study examined one component of marketing HMOs--the method of communicating the HMO's attributes. The purpose of the analysis was to determine if characteristics of Medicaid beneficiaries who enroll in HMOs vary by method of communicating information about health plan options. Data were analyzed from the marketing component of California's Prepaid Health Research, Evaluation, and Demonstration (PHRED) project. Five communication methods are examined in the article: brochure, film, county eligibility worker presentation, state representative presentation, and HMO representative presentation. The analysis reveals that each communication method is most effective with a different type of beneficiary. No single consumer characteristic is related to HMO enrollment across all five methods, although lack of a private physician and dissatisfaction with a current provider are associated with choice in four methods. Film is the best method for attracting persons who have an ongoing relationship with a provider. PMID:2668236

Rock climbing: A local-global algorithm to compute minimum energy and minimum free energy pathways.

Templeton, Clark; Chen, Szu-Hua; Fathizadeh, Arman; Elber, Ron

2017-10-21

The calculation of minimum energy or minimum free energy paths is an important step in the quantitative and qualitative studies of chemical and physical processes. The computations of these coordinates present a significant challenge and have attracted considerable theoretical and computational interest. Here we present a new local-global approach to study reaction coordinates, based on a gradual optimization of an action. Like other global algorithms, it provides a path between known reactants and products, but it uses a local algorithm to extend the current path in small steps. The local-global approach does not require an initial guess to the path, a major challenge for global pathway finders. Finally, it provides an exact answer (the steepest descent path) at the end of the calculations. Numerical examples are provided for the Mueller potential and for a conformational transition in a solvated ring system.

2014-01-01

Schizophrenia Research: Cognition will serve an important function – a place where interests converge and investigators can learn about the recent developments in this area. This new journal will provide rapid dissemination of information to people who will make good use of it. In this initial article, we comment globally on the study of cognition in schizophrenia: how we got here, where we are, and where we are going. The goal of this first article is to place the study of cognition in schizophrenia within a historical and scientific context. In a field as richly textured as ours it is impossible to hit all the important areas, and we hope the reader will forgive our omissions. Phrased in cognitive terms, our limited presentation of the past is a matter of selective memory, the present is a matter of selective attention, and the future is a matter of selective prospection. This broad introduction emphasizes that cognition in schizophrenia provides clues to pathophysiology, treatment, and outcome. In fact, the study of cognitive impairment in schizophrenia has become wholly intertwined with the study of schizophrenia itself. PMID:25254156

No longer 'flying blind': how access has changed emergency mental health care in rural and remote emergency departments, a qualitative study.

PubMed

Saurman, Emily; Kirby, Sue E; Lyle, David

2015-04-14

Mental health presentations are considered to be a difficult aspect of emergency care. Although emergency department (ED) staff is qualified to provide emergency mental health care, for some, such presentations pose a challenge to their training, confidence, and time. Providing access to relevant and responsive specialist mental health care can influence care and management for these patients. The Mental Health Emergency Care-Rural Access Program (MHEC-RAP) is a telepsychiatry program that was established to improve access to specialist emergency mental health care across rural and remote western NSW, Australia. This study uses interviews with ED providers to understand their experience of managing emergency mental health patients and their use of MHEC-RAP. The lens of access was applied to assess program impact and inform continuing program development. With MHEC-RAP, these ED providers are no longer 'flying blind'. They are also more confident to manage and care for emergency mental health patients locally. For these providers, access to specialists who are able to conduct assessments and provide relevant and responsive advice for emergency mental health presentations was valued. Assessing the fit between the consumer and service as a requirement for the development, evaluation, and ongoing management of the service should result in decisions about design and delivery that achieve improved access to care and meet the needs of their consumers. The experience of these providers prior to MHEC-RAP is consistent with that reported in other rural and remote populations suggesting that MHEC-RAP could address limitations in access to specialist care and change the provision of emergency mental health care elsewhere. MHEC-RAP has not only provided access to specialist mental health care for local ED providers, but it has changed their practice and perspective. MHEC-RAP could be adapted for implementation elsewhere. Provider experience confirms that the program is accessible and offers insights to those considering how to establish an emergency telepyschiatry service in other settings.

General fuel cell hybrid synergies and hybrid system testing status

NASA Astrophysics Data System (ADS)

Winkler, Wolfgang; Nehter, Pedro; Williams, Mark C.; Tucker, David; Gemmen, Randy

FCT hybrid power systems offer the highest efficiency and the cleanest emissions of all fossil fuelled power. The engineering for the highest possible efficiency at lowest cost and weight depends on general system architecture issues and the performance of the components. Presented in this paper are system studies which provide direction for the most efficient path toward achieving the most beneficial result for this technology. Ultimately, fuel cell-turbine (FCT) hybrid systems applicable to integrated gasification combined cycle power systems will form the basis for reaching the goals for advanced coal-based power generation. The FCT hybrid power island will also be important for the FutureGen plant and will provide new options for carbon dioxide capture and sequestration as well as power and hydrogen generation. The system studies presented in this paper provide insight to current technology 'benchmarks' versus expected benefits from hybrid applications. Discussion is also presented on the effects of different balance of plant arrangements and approaches. Finally, we discuss the status of US DOE is sponsored projects that are looking to help understand the unique requirements for these systems. One of these projects, Hyper, will provide information on FCT dynamics and will help identify technical needs and opportunities for cycle advancement. The methods studied show promise for effective control of a hybrid system without the direct intervention of isolation valves or check valves in the main pressure loop of the system, which introduce substantial pressure losses, allowing for realization of the full potential efficiency of the hybrid system.

Current diagnosis and management of infectious mononucleosis.

PubMed

Vouloumanou, Evridiki K; Rafailidis, Petros I; Falagas, Matthew E

2012-01-01

Infectious mononucleosis is a common, usually self-limited disease. However, infectious mononucleosis may present with severe manifestations. Complications may also occur. Consequently, diagnostic and treatment issues regarding infectious mononucleosis are of major importance. In this review, we focus on the evaluation of articles providing diagnosis and treatment data for infectious mononucleosis, published during the past 2 years. Twelve studies, deriving from extended search in PubMed, were included. Nine studies provided diagnosis data. The evaluated diagnostic methods were real-time PCR (RT-PCR), IgM/IgG antibodies measured with different assays [measurement of Epstein-Barr virus viral load (EBV-VL) in peripheral blood, neutrophil/lymphocyte/monocyte counts, C-reactive protein values, and monospot test]. The sensitivities reported for RT-PCR were high. The available treatment data were scarce (three studies). Two of them suggested that antivirals (mainly acyclovir and valacyclovir) may have a role in the treatment of infectious mononucleosis with complications, whereas the remaining study presented novel potential therapeutic patents including 5-substituted uracyle, azacytosine derivatives, and peptides inhibiting EBV-mediated membrane fusion. RT-PCR and measurement of EBV-VL may provide useful tools for the early diagnosis of infectious mononucleosis in cases with inconclusive serological results. Antiviral agents may provide a useful treatment option in patients with severe infectious mononucleosis.

Adams, C.E.; Berger, T.J.; Boicourt, W.C.

The present study is part of a sequence of programs designed to provide the MMS with a basis for evaluating the potential environmental impacts of oil and gas production off of the Cape Hatteras region. The primary objective of this review is to summarize and critique the present state of knowledge of the physical oceanography of the complex region offshore of Cape Hatteras, North Carolina, within the context of understanding the regional circulation and its relation to the fate of any discharges resulting from offshore oil and gas activity. The two other related objectives are to produce an annotated bibliographymore » of the pertinent literature, primarily from 1970 to the present, and to identify relevant oceanographic data sets which can provide a basis for an improved understanding of circulation patterns and physical oceanographic conditions in the study area.« less

How the bimodal format of presentation affects working memory: an overview.

2008-03-01

The best format in which information that has to be recalled is presented has been investigated in several studies, which focused on the impact of bimodal stimulation on working memory performance. An enhancement of participant's performance in terms of correct recall has been repeatedly found, when bimodal formats of presentation (i.e., audiovisual) were compared to unimodal formats (i.e, either visual or auditory), in providing implications for multimedial learning. Several theoretical frameworks have been suggested in order to account for the bimodal advantage, ranging from those emphasizing early stages of processing (such as automatic alerting effects or multisensory integration processes) to those centred on late stages of processing (as postulated by the dual coding theory). The aim of this paper is to review previous contributions to this topic, providing a comprehensive theoretical framework, which is updated by the latest empirical studies.

Community pharmacies in the United Kingdom (UK) provide sexual and reproductive health (SRH) services such as emergency contraception (EC), although there is scope for provision of additional services. We conducted a pilot study of pharmacy based interventions for initiating effective contraception after EC. By determining the views of participating women and pharmacists we aimed to identify barriers and facilitators to providing interventions from pharmacies routinely. In the pilot study, women presenting for levonorgestrel EC to community pharmacies, were provided with either standard care or one of two interventions: one packet of progestogen-only pills (POPs); or an invitation to present the empty EC packet to a local family planning clinic for contraception. A sample of women participating were asked to undergo a further interview. Operational difficulties with research in the community pharmacy were also documented by the research team. Semi-structured interviews were conducted with 12 women, four from each arm of the pilot study, using a standardised topic guide. Pre- and post-study interviews were conducted with the pharmacists involved. All women welcomed the interventions indicating the benefit of having different options available. They also identified possible advantages and disadvantages of each intervention. All pharmacists were positive about their involvement in the study. Methodological problems included difficulty in retention of participating pharmacists, slow recruitment and failure to accurately complete study paperwork. Women welcomed the interventions offered. Pharmacists viewed their participation in the study positively. The problems encountered provide valuable feedback to inform the development larger scale studies of such interventions.

Airway growth and development: a computerized 3-dimensional analysis.

PubMed

Schendel, Stephen A; Jacobson, Richard; Khalessi, Sadri

2012-09-01

The present study was undertaken to investigate the changes in the normal upper airway during growth and development using 3-dimensional computer analysis from cone-beam computed tomography (CBCT) data to provide a normative reference. The airway size and respiratory mode are known to have a relationship to facial morphology and the development of a malocclusion. The use of CBCT, 3-dimensional imaging, and automated computer analysis in treatment planning allows the upper airway to be precisely evaluated. In the present study, we evaluated the growth of the airway using 3-dimensional analysis and CBCT data from age 6 through old age, in 1300 normal individuals. The airway size and length increase until age 20 at which time a variable period of stability occurs. Next, the airway at first decreases slowly in size and then, after age 40, more rapidly. Normative data are provided in the present study for age groups from 6 to 60 years in relation to the airway total volume, smallest cross-sectional area and vertical length of the airway. This 3-dimensional data of the upper airway will provide a normative reference as an aid in the early understanding of respiration and dentofacial anatomy, which will help in early treatment planning.

The three dimensional-quantitative structure activity relationship (3D-QSAR) study was performed on a series of 4-hydroxyamino α-pyranone carboxamide analogues using comparative molecular similarity indices analysis (COMSIA). The purpose of the present study was to develop a satisfactory model providing a reliable prediction based on 4-hydroxyamino α-pyranone carboxamide analogues as anti-HCV (hepatitis C virus) inhibitors. The statistical results and the results of validation of this optimum COMSIA model were satisfactory. Furthermore, analysis of the contour maps helped to provide guidelines for finding structural requirement. Therefore, the satisfactory results from this study may provide useful guidelines for drug development of anti-HCV inhibitors.

Discrete Molecular Dynamics Approach to the Study of Disordered and Aggregating Proteins.

PubMed

Emperador, Agustí; Orozco, Modesto

2017-03-14

We present a refinement of the Coarse Grained PACSAB force field for Discrete Molecular Dynamics (DMD) simulations of proteins in aqueous conditions. As the original version, the refined method provides good representation of the structure and dynamics of folded proteins but provides much better representations of a variety of unfolded proteins, including some very large, impossible to analyze by atomistic simulation methods. The PACSAB/DMD method also reproduces accurately aggregation properties, providing good pictures of the structural ensembles of proteins showing a folded core and an intrinsically disordered region. The combination of accuracy and speed makes the method presented here a good alternative for the exploration of unstructured protein systems.

Introduction One in five patients with sepsis deteriorates within 48 hours after hospital admission. Regrettably, a clear tool for the early detection of deterioration is still lacking. The SepsiVit study aims to determine whether continuous heart rate variability (HRV) measurement can provide an early warning for deterioration in patients presenting with suspected infection or sepsis to the emergency department (ED). Methods and analysis The protocol of a prospective observational study in the ED. We will include 171 adult medical patients presenting with suspected infection or sepsis and at least two systemic inflammatory response syndrome criteria. Patients with known pregnancy, cardiac transplantation or not admitted to our hospital are excluded. High sample frequency ECG signals (500 Hz), respiratory rate, blood pressure and peripheral oxygen saturation will be recorded continuously during the first 48 hours of hospitalisation using a bedside patient monitor (Philips IntelliVue MP70). Primary endpoint is patient deterioration, defined as the development of organ dysfunction, unplanned intensive care unit admission or in-hospital mortality. The ECG data will be used for offline HRV analysis. We will compare the HRV between two groups (deterioration/no deterioration) and analyse whether HRV provides an early warning for deterioration. Furthermore, we will create a multivariate predictive model for deterioration based on heart rate, respiratory rate and HRV. As planned secondary analyses, we (1) perform a subgroup analysis for patients with pneumosepsis and urosepsis and (2) determine whether HRV using lower sample frequencies (1 Hz or less) suffices to predict deterioration. Ethics and dissemination The Institutional Review Board of the University Medical Center Groningen granted a waiver for the study (METc 2015/164). Results will be disseminated through international peer-reviewed publications and conference presentations. A lay summary of the results will be provided to the study participants.

In support of natural resource and ecosystem service policy, monetary value estimates are often presented to decision makers along with other types of information. There is some evidence that, presented with such 'mixed' information, people prioritise monetary over non-monetary information. We conduct a discrete choice experiment among New Zealand decision makers in which we manipulate the information presented to participants. We find that providing explicit monetary information strengthens the pursuit of economic benefits as well as the avoidance of environmental damage. Cultural impacts, of which we provided only qualitative descriptions, did not affect respondents' choices. Our study provides further evidence that concerns regarding the use of monetary information in decisions with complex, multi-value impacts are valid. Further research is needed to validate our results and find ways to reduce any bias in monetary and non-market information.

Optimal shaping of aerospace trajectories has provided the motivation for much modern study of optimization theory and algorithms. Current industrial practice favors approaches where the continuous-time optimal control problem is transcribed to a finite-dimensional nonlinear programming problem (NLP) by a discretization process. Two such formulations are implemented in the POST and the OTIS codes. In the present paper we use a discretization that is specially adapted to the flight problem of interest. Among the unique aspects of the present discretization are: a least-squares formulation for certain kinematic constraints; the use of an energy ideas to enforce Newton`s Laws; and, themore » inclusion of large magnitude horizontal winds. In the next section we shall provide a description of the flight problem and its NLP representation. Following this we provide some details of the constraint formulation.

Government of India in 2008, launched its flagship health insurance scheme for the poor. The Rashtriya Swasthya Bima Yojana (RSBY) combines cutting edge technology with an unusual reliance on incentives to provide inpatient insurance coverage. The scheme allows for cashless hospitalization services at any of the empaneled hospitals. Stakeholders in RSBY include members of the community, Insurance Company and the service provider. The study manuscript is an attempt to get an insight to understand the bottle necks in faced by the service providers with an overall goal to understand issues in complete roll out of RSBY and its successful implementation across country. It was conducted to undertake the stakeholder analysis and understand the service providers' perspective to RSBY. The present study was conducted in the Patan district of Gujarat state. Qualitative tool mainly in-depth interview of service providers of RSBY in Patan district of Gujarat state was utilized for the data collection. Service providers opined an ineffective IEC around the utility of the RSBY service in the community. In spite of the claim that scheme relies heavily on technology to ensure paperless cashless services, on field, it was observed in the present study that the claim settlements are done through physical documents. The service providers had a perceived threat of being suspended from the list/de-empanelment of the provider by the insurance company. There is an urgent need for improved and effective IEC for the service and possibilities of an arrangement for to settle the case of grievances around suspensions ao that genuine hospitals can have fair deal as well. There definitely remains a greater and more serious role of government, which ranges from ownership to larger issue of governance.

Autonomous aerial observations to extend and complement the Earth Observing System: a science-driven systems-oriented approach

The current Earth observing capability depends primarily on spacecraft missions and ground-based networks to provide the critical on-going observations necessary for improved understanding of the Earth system. Aircraft missions play an important role in process studies but are limited to relatively short-duration flights. Suborbital observations have contributed to global environmental knowledge by providing in-depth, high-resolution observations that space-based and in-situ systems are challenged to provide; however, the limitations of aerial platforms - e.g., limited observing envelope, restrictions associated with crew safety and high cost of operations have restricted the suborbital program to a supporting role. For over a decade, it has been recognized that autonomous aerial observations could potentially be important. Advances in several technologies now enable autonomous aerial observation systems (AAOS) that can provide fundamentally new observational capability for Earth science and applications and thus lead scientists and engineers to rethink how suborbital assets can best contribute to Earth system science. Properly developed and integrated, these technologies will enable new Earth science and operational mission scenarios with long term persistence, higher-spatial and higher-temporal resolution at lower cost than space or ground based approaches. This paper presents the results of a science driven, systems oriented study of broad Earth science measurement needs. These needs identify aerial mission scenarios that complement and extend the current Earth Observing System. These aerial missions are analogous to space missions in their complexity and potential for providing significant data sets for Earth scientists. Mission classes are identified and presented based on science driven measurement needs in atmospheric, ocean and land studies. Also presented is a nominal concept of operations for an AAOS: an innovative set of suborbital assets that complements and augments current and planned space-based observing systems.

Mental illness stigma and engagement in an implementation trial for Cognitive Processing Therapy at a diverse community health center: a qualitative investigation.

PubMed

Valentine, Sarah E; Dixon, Louise; Borba, Christina P C; Shtasel, Derri L; Marques, Luana

The present study aimed to describe associations between various types of mental health stigma and help-seeking behaviors among ethnically diverse clients with posttraumatic stress disorder (PTSD) served by an urban community health clinic. The present study draws qualitative data from a parent National Institute of Mental Health Study that aims to identify barriers and facilitators of implementing Cognitive Processing Therapy (CPT) for PTSD. A total of 24 participants from the initial phase of the trial were included in the present study. Mental health stigma emerged as one notable barrier to seeking mental health treatment, as participants described how experiences of environment-level stigma, internalized (self-)stigma and perceived (felt) stigma from their family, friends and previous healthcare providers influenced their decisions to seek care. Despite these barriers to help seeking, many clients also reported that positive interactions with informal and formal support systems, and encouragement from study therapists, helped to combat mental health stigma and facilitate decisions to participate in an implementation trial for CPT. Findings suggest that providers in community health settings may need to attend directly to stigma at the initiation of mental health treatment.

Job Satisfaction of Primary Health-Care Providers (Public Sector) in Urban Setting

PubMed Central

Kumar, Pawan; Khan, Abdul Majeed; Inder, Deep; Sharma, Nandini

2013-01-01

Introduction: Job satisfaction is determined by a discrepancy between what one wants in a job and what one has in a job. The core components of information necessary for what satisfies and motivates the health work force in our country are missing at policy level. Therefore present study will help us to know the factors for job satisfaction among primary health care providers in public sector. Materials and Methods: Present study is descriptive in nature conducted in public sector dispensaries/primary urban health centers in Delhi among health care providers. Pretested structured questionnaire was administered to 227 health care providers. Data was analyzed using SPSS and relevant statistical test were applied. Results: Analysis of study reveals that ANMs are more satisfied than MOs, Pharmacist and Lab assistants/Lab technicians; and the difference is significant (P < 0.01). Age and education level of health care providers don’t show any significant difference in job satisfaction. All the health care providers are dissatisfied from the training policies and practices, salaries and opportunities for career growth in the organization. Majority of variables studied for job satisfaction have low scores. Five factor were identified concerned with job satisfaction in factor analysis. Conclusion: Job satisfaction is poor for all the four groups of health care providers in dispensaries/primary urban health centers and it is not possible to assign a single factor as a sole determinant of dissatisfaction in the job. Therefore it is recommended that appropriate changes are required at the policy as well as at the dispensary/PUHC level to keep the health work force motivated under public sector in Delhi.

Guidance for deriving and presenting percentage study weights in meta-analysis of test accuracy studies.

PubMed

Burke, Danielle L; Ensor, Joie; Snell, Kym I E; van der Windt, Danielle; Riley, Richard D

2018-06-01

Percentage study weights in meta-analysis reveal the contribution of each study toward the overall summary results and are especially important when some studies are considered outliers or at high risk of bias. In meta-analyses of test accuracy reviews, such as a bivariate meta-analysis of sensitivity and specificity, the percentage study weights are not currently derived. Rather, the focus is on representing the precision of study estimates on receiver operating characteristic plots by scaling the points relative to the study sample size or to their standard error. In this article, we recommend that researchers should also provide the percentage study weights directly, and we propose a method to derive them based on a decomposition of Fisher information matrix. This method also generalises to a bivariate meta-regression so that percentage study weights can also be derived for estimates of study-level modifiers of test accuracy. Application is made to two meta-analyses examining test accuracy: one of ear temperature for diagnosis of fever in children and the other of positron emission tomography for diagnosis of Alzheimer's disease. These highlight that the percentage study weights provide important information that is otherwise hidden if the presentation only focuses on precision based on sample size or standard errors. Software code is provided for Stata, and we suggest that our proposed percentage weights should be routinely added on forest and receiver operating characteristic plots for sensitivity and specificity, to provide transparency of the contribution of each study toward the results. This has implications for the PRISMA-diagnostic test accuracy guidelines that are currently being produced. Copyright © 2017 John Wiley & Sons, Ltd.

Culture and social support provision: who gives what and why.

Chen, Jacqueline M; Kim, Heejung S; Mojaverian, Taraneh; Morling, Beth

2012-01-01

The present research examined cultural differences in the type and frequency of support provided as well as the motivations underlying these behaviors. Study 1, an open-ended survey, asked participants about their social interactions in the past 24 hours and found that European Americans reported providing emotion-focused support more frequently than problem-focused support, whereas Japanese exhibited the opposite pattern. Study 2, a closed-ended questionnaire study, found that, in response to the close other's big stressor, European Americans provided more emotion-focused support whereas Japanese provided equivalent amounts of emotion-focused and problem-focused support. In addition, Study 2 examined motivational explanations for these differences. Social support provision was motivated by the goal of closeness and increasing recipient self-esteem among European Americans, but only associated with the motive for closeness among Japanese. These studies illustrate the importance of considering cultural context and its role in determining the meaning and function of various support behaviors.

A Global Meta-Analysis of the Value of Ecosystem Services Provided by Lakes.

PubMed

Reynaud, Arnaud; Lanzanova, Denis

2017-07-01

This study presents the first meta-analysis on the economic value of ecosystem services delivered by lakes. A worldwide data set of 699 observations drawn from 133 studies combines information reported in primary studies with geospatial data. The meta-analysis explores antagonisms and synergies between ecosystem services. This is the first meta-analysis to incorporate simultaneously external geospatial data and ecosystem service interactions. We first show that it is possible to reliably predict the value of ecosystem services provided by lakes based on their physical and geographic characteristics. Second, we demonstrate that interactions between ecosystem services appear to be significant for explaining lake ecosystem service values. Third, we provide an estimation of the average value of ecosystem services provided by lakes: between 106 and 140 USD$2010 per respondent per year for non-hedonic price studies and between 169 and 403 USD$2010 per property per year for hedonic price studies.

Information presentation features and comprehensibility of hospital report cards: design analysis and online survey among users.

2015-03-16

Improving the transparency of information about the quality of health care providers is one way to improve health care quality. It is assumed that Internet information steers patients toward better-performing health care providers and will motivate providers to improve quality. However, the effect of public reporting on hospital quality is still small. One of the reasons is that users find it difficult to understand the formats in which information is presented. We analyzed the presentation of risk-adjusted mortality rate (RAMR) for coronary angiography in the 10 most commonly used German public report cards to analyze the impact of information presentation features on their comprehensibility. We wanted to determine which information presentation features were utilized, were preferred by users, led to better comprehension, and had similar effects to those reported in evidence-based recommendations described in the literature. The study consisted of 5 steps: (1) identification of best-practice evidence about the presentation of information on hospital report cards; (2) selection of a single risk-adjusted quality indicator; (3) selection of a sample of designs adopted by German public report cards; (4) identification of the information presentation elements used in public reporting initiatives in Germany; and (5) an online panel completed an online questionnaire that was conducted to determine if respondents were able to identify the hospital with the lowest RAMR and if respondents' hospital choices were associated with particular information design elements. Evidence-based recommendations were made relating to the following information presentation features relevant to report cards: evaluative table with symbols, tables without symbols, bar charts, bar charts without symbols, bar charts with symbols, symbols, evaluative word labels, highlighting, order of providers, high values to indicate good performance, explicit statements of whether high or low values indicate good performance, and incomplete data ("N/A" as a value). When investigating the RAMR in a sample of 10 hospitals' report cards, 7 of these information presentation features were identified. Of these, 5 information presentation features improved comprehensibility in a manner reported previously in literature. To our knowledge, this is the first study to systematically analyze the most commonly used public reporting card designs used in Germany. Best-practice evidence identified in international literature was in agreement with 5 findings about German report card designs: (1) avoid tables without symbols, (2) include bar charts with symbols, (3) state explicitly whether high or low values indicate good performance or provide a "good quality" range, (4) avoid incomplete data (N/A given as a value), and (5) rank hospitals by performance. However, these findings are preliminary and should be subject of further evaluation. The implementation of 4 of these recommendations should not present insurmountable obstacles. However, ranking hospitals by performance may present substantial difficulties.

NASA Technical Reports Server (NTRS)

Gregory, G. L.; Mcdougal, D. S.; Mathis, J. J., Jr.

1980-01-01

Ozone data from the 1979 Southeastern Virginia Urban Study (SEV-UPS) field program are presented. The SEV-UPS was conducted for evaluation of an ozone remote sensor, the Laser Absorption Spectrometer. During the measurement program, remote-sensor evaluation was in two areas; (1) determination of the remote sensor's accuracy, repeatability, and operational characteristics, and (2) demonstration of the application of remotely sensed ozone data in air-quality studies. Data from six experiments designed to provide in situ ozone data for evaluation of the sensor in area 1, above, are presented. Experiments consisted of overflights of a test area with the remote sensor aircraft while in situ measurements with a second aircraft and selected surface stations provided correlative ozone data within the viewing area of the remote sensor.

Workload and casemix in Cape Town emergency departments.

Wallis, Lee A; Twomey, Michele

2007-12-01

Little is known about the nature of patients presenting to emergency departments (EDs) in South Africa. This study aimed to provide evidence on ED usage in Cape Town by studying patients at four community health centre (CHC) EDs, with details of the severity of their presentation and their disposal. A total of 16,392 patients presented in this 8-week prospective observational study, and 15,681 were included in the descriptive data analysis. One-quarter were children. There were clear and predictable peaks in attendance after 1600 hr and at weekends, with a steady stream of patients presenting overnight. Case severity was evenly distributed between emergency, urgent and routine care. Nearly 10% of patients were referred on to a higher level of care. The data from this study present a model for staffing and resource allocation. It has implications for the provision of emergency care in CHC EDs.

Reliability associated with the Roter Interaction Analysis System (RIAS) adapted for the telemedicine context.

Nelson, Eve-Lynn; Miller, Edward Alan; Larson, Kiley A

2010-01-01

This study's purpose was to adapt the Roter Interaction Analysis System (RIAS) for telemedicine clinics and to investigate the adapted measure's reliability. The study also sought to better understand the volume of technology-related utterance in established telemedicine clinics and the feasibility of using the measure within the telemedicine setting. This initial evaluation is a first step before broadly using the adapted measure across technologies and raters. An expert panel adapted the RIAS for the telemedicine context. This involved accounting for all consultation participants (patient, provider, presenter, family) and adding technology-specific subcategories. Ten new and 36 follow-up telemedicine encounters were videotaped and double coded using the adapted RIAS. These consisted primarily of follow-up visits (78.0%) involving patients, providers, presenters, and other parties. Reliability was calculated for those categories with 15 or more utterances. Traditional RIAS categories related to socioemotional and task-focused clusters had fair to excellent levels of reliability in the telemedicine setting. Although there were too few utterances to calculate the reliability of the specific technology-related subcategories, the summary technology-related category proved reliable for patients, providers, and presenters. Overall patterns seen in traditional patient-provider interactions were observed, with the number of provider utterances far exceeding patient, presenter, and family utterances, and few technology-specific utterances. The traditional RIAS is reliable when applied across multiple participants in the telemedicine context. Reliability of technology-related subcategories could not be evaluated; however, the aggregate technology-related cluster was found to be reliable and may be especially relevant in understanding communication patterns with patients new to the telemedicine setting. Use of the RIAS instrument is encouraged to facilitate comparison between traditional, face-to-face clinics and telemedicine; among diverse consultation mediums and technologies; and across different specialties. Future research is necessary to further investigate the reliability and validity of adding technology-related subcategories to the RIAS. The limited number of technology-related utterances, however, implies a certain degree of comfort with two-way interactive video consultation among study participants. Telemedicine continues to increase access to healthcare. The technology-related categories of the adapted RIAS were reliable when aggregated, thereby providing a tool to better understand how telemedicine affects provider-patient communication and outcomes.

Projection of wave conditions in response to climate change: A community approach to global and regional wave downscaling

USGS Publications Warehouse

Erikson, Li H.; Hemer, M.; Lionello, Piero; Mendez, Fernando J.; Mori, Nobuhito; Semedo, Alvaro; Wang, Xiaolan; Wolf, Judith

2015-01-01

Future changes in wind-wave climate have broad implications for coastal geomorphology and management. General circulation models (GCM) are now routinely used for assessing climatological parameters, but generally do not provide parameterizations of ocean wind-waves. To fill this information gap, a growing number of studies use GCM outputs to independently downscale wave conditions to global and regional levels. To consolidate these efforts and provide a robust picture of projected changes, we present strategies from the community-derived multi-model ensemble of wave climate projections (COWCLIP) and an overview of regional contributions. Results and strategies from one contributing regional study concerning changes along the eastern North Pacific coast are presented.

Cognition and Behaviour in Sotos Syndrome: A Systematic Review

PubMed Central

Lane, Chloe; Milne, Elizabeth; Freeth, Megan

2016-01-01

Background Research investigating cognition and behaviour in Sotos syndrome has been sporadic and to date, there is no published overview of study findings. Method A systematic review of all published literature (1964–2015) presenting empirical data on cognition and behaviour in Sotos syndrome. Thirty four journal articles met inclusion criteria. Within this literature, data relating to cognition and/or behaviour in 247 individuals with a diagnosis of Sotos syndrome were reported. Ten papers reported group data on cognition and/or behaviour. The remaining papers employed a case study design. Results Intelligence quotient (IQ) scores were reported in twenty five studies. Intellectual disability (IQ < 70) or borderline intellectual functioning (IQ 70–84) was present in the vast majority of individuals with Sotos syndrome. Seven studies reported performance on subscales of intelligence tests. Data from these studies indicate that verbal IQ scores are consistently higher than performance IQ scores. Fourteen papers provided data on behavioural features of individuals with Sotos syndrome. Key themes that emerged in the behavioural literature were overlap with ASD, ADHD, anxiety and high prevalence of aggression/tantrums. Conclusion Although a range of studies have provided insight into cognition and behaviour in Sotos syndrome, specific profiles have not yet been fully specified. Recommendations for future research are provided. PMID:26872390

The Mechanisms of Manual Therapy in the Treatment of Musculoskeletal Pain: A Comprehensive Model

PubMed Central

Bialosky, Joel E; Bishop, Mark D; Price, Don D; Robinson, Michael E; George, Steven Z

2009-01-01

Prior studies suggest manual therapy (MT) as effective in the treatment of musculoskeletal pain; however, the mechanisms through which MT exerts its effects are not established. In this paper we present a comprehensive model to direct future studies in MT. This model provides visualization of potential individual mechanisms of MT that the current literature suggests as pertinent and provides a framework for the consideration of the potential interaction between these individual mechanisms. Specifically, this model suggests that a mechanical force from MT initiates a cascade of neurophysiological responses from the peripheral and central nervous system which are then responsible for the clinical outcomes. This model provides clear direction so that future studies may provide appropriate methodology to account for multiple potential pertinent mechanisms. PMID:19027342

2009-04-01

Staff retention is an ongoing challenge in mental health and community-based service organizations. Little is known about the impact of evidence-based practice implementation on the mental health and social service workforce. The present study examined the effect of evidence-based practice implementation and ongoing fidelity monitoring on staff retention in a children's services system. The study took place in the context of a statewide, regionally randomized effectiveness trial of an evidence-based intervention designed to reduce child neglect. In the study 21 teams consisting of 153 home-based service providers were followed over a 29-month period. Survival analyses revealed greater staff retention in the condition where the evidence-based practice was implemented along with ongoing fidelity monitoring presented to staff as supportive consultation. These results should help to allay concerns about staff retention when implementing evidence-based practices where there is good values-innovation fit and when fidelity monitoring is designed as an aid and support to service providers in providing a high standard of care for children and families.

FFQ, food diaries and 24 h recall methods represent the most commonly used dietary assessment tools in human studies on nutrition and health, but food intake biomarkers are assumed to provide a more objective reflection of intake. Unfortunately, very few of these biomarkers are sufficiently validated. This review provides an overview of food intake biomarker research and highlights present research efforts of the Joint Programming Initiative 'A Healthy Diet for a Healthy Life' (JPI-HDHL) Food Biomarkers Alliance (FoodBAll). In order to identify novel food intake biomarkers, the focus is on new food metabolomics techniques that allow the quantification of up to thousands of metabolites simultaneously, which may be applied in intervention and observational studies. As biomarkers are often influenced by various other factors than the food under investigation, FoodBAll developed a food intake biomarker quality and validity score aiming to assist the systematic evaluation of novel biomarkers. Moreover, to evaluate the applicability of nutritional biomarkers, studies are presently also focusing on associations between food intake biomarkers and diet-related disease risk. In order to be successful in these metabolomics studies, knowledge about available electronic metabolomics resources is necessary and further developments of these resources are essential. Ultimately, present efforts in this research area aim to advance quality control of traditional dietary assessment methods, advance compliance evaluation in nutritional intervention studies, and increase the significance of observational studies by investigating associations between nutrition and health.

Providing information about a flavor to preschoolers: effects on liking and memory for having tasted it.

Lumeng, Julie C; Cardinal, Tiffany M

2007-07-01

This study sought to determine if providing affectively positive information about a flavor to preschool-aged children during tasting will increase recognition of and liking for the flavor and if the recognition and liking are associated. Forty-six 3- to 6-year-old children tasted 10 flavors: 5 presented with affectively positive information and 5 without. The 10 flavors were then presented again interspersed with 10 distracter flavors. Children reported whether they had tasted the flavor previously and provided hedonic ratings for each flavor. Children's ability to remember having tasted a flavor was greater when the flavor was presented with affectively positive information than without in children throughout the age range of 3-6 years. In children younger than 4.5 years, the provision of information had no effect on hedonic rating, whereas in older children, the provision of information was associated with greater hedonic ratings. We conclude that providing affectively positive information to children about a flavor can increase their ability to recognize the flavor as previously tasted and increases hedonic rating of the flavor in children older than 4.5 years.

Israel has provided immediate healthcare to Syrian children, civilians and fighters since early 2013 despite being in an official state of war with Syria since 1973. We present qualitative findings from a larger mixed-methods phenomenological study to understand how the geopolitical and social history of Israel and Syria influences healthcare providers and Syrian patient caregivers in northern Israel. Theories of humanization and cognitive dissonance guided this study and frame the beliefs and experiences of healthcare providers who treated wounded Syrians in Israeli hospitals. Findings indicate healthcare providers and Syrian caregivers adjusted their beliefs to allow for positive healthcare experiences. Qualitative analysis revealed two major themes: supportive and hindering systemic elements contributing to the healthcare provider-patient-caregiver relationship. Internal psychological developments, contextual factors, and relational processes influenced humanization of the other within the relationship. This study illuminates unique ethical and humanitarian demands relevant for healthcare workers and those with whom they interact. PMID:28508018

Combined Volatolomics for Monitoring of Human Body Chemistry

Analysis of volatile organic compounds (VOCs) is a promising approach for non-invasive, fast and potentially inexpensive diagnostics. Here, we present a new methodology for profiling the body chemistry by using the volatile fraction of molecules in various body fluids. Using mass spectrometry and cross-reactive nanomaterial-based sensors array, we demonstrate that simultaneous VOC detection from breath and skin would provide complementary, non-correlated information of the body's volatile metabolites profile. Eventually with further wide population validation studies, such a methodology could provide more accurate monitoring of pathological changes compared to the information provided by a single body fluid. The qualitative and quantitative methods presented here offers a variety of options for novel mapping of the metabolic properties of complex organisms, including humans. PMID:24714440

Project Career is an interprofessional five-year development project designed to improve the employment success of undergraduate college and university students with traumatic brain injury (TBI). The case study information was collected and synthesized by the project's Technology and Employment Coordinators (TECs) at each of the project's three university sites. The project's evaluation is occurring independently through JBS International, Inc. Five case studies are presented to provide an understanding of student participants' experiences within Project Career. Each case study includes background on the student, engagement with technology, vocational supports, and interactions with his/her respective TEC. A qualitative analysis from the student's case notes is provided within each case study, along with a discussion of the overall qualitative analysis. Across all five students, the theme Positive Outcomes was mentioned most often in the case notes. Of all the different type of challenges, Cognitive Challenges were most often mentioned during meetings with the TECs, followed by Psychological Challenges, Physical Challenges, Other Challenges, and Academic Challenges, respectively. Project Career is providing academic enrichment and career enhancement that may substantially improve the unsatisfactory employment outcomes that presently await students with TBI following graduation.

Subject recruitment for medical research is challenging. Slow patient accrual leads to increased costs and delays in treatment advances. Researchers need reliable tools to manage and predict the accrual rate. The previously developed Bayesian method integrates researchers' experience on former trials and data from an ongoing study, providing a reliable prediction of accrual rate for clinical studies. In this paper, we present a user-friendly graphical user interface program developed in R. A closed-form solution for the total subjects that can be recruited within a fixed time is derived. We also present a built-in Android system using Java for web browsers and mobile devices. Using the accrual software, we re-evaluated the Veteran Affairs Cooperative Studies Program 558- ROBOTICS study. The application of the software in monitoring and management of recruitment is illustrated for different stages of the trial. This developed accrual software provides a more convenient platform for estimation and prediction of the accrual process.

Abstract This study provides a comprehensive review of historical morphological nomenclature used for praying mantis (Mantodea) morphology, which includes citations, original use, and assignment of homology. All referenced structures across historical works correspond to a proposed standard term for use in all subsequent works pertaining to praying mantis morphology and systematics. The new standards are presented with a verbal description in a glossary as well as indicated on illustrations and images. In the vast majority of cases, originally used terms were adopted as the new standard. In addition, historical morphological topographical homology conjectures are considered with discussion on modern interpretations. A new standardized formulation to present foreleg femoral and tibial spines is proposed for clarity based on previous works. In addition, descriptions for methods of collection, curation, genital complex dissection, and labeling are provided to aid in the proper preservation and storage of specimens for longevity and ease of study. Due to the lack of consistent linear morphometric measurement practices in the literature, we have proposed a series of measurements for taxonomic and morphological research. These measurements are presented with figures to provide visual aids with homologous landmarks to ensure compatibility and comparability across the Order. Finally, our proposed method of pinning mantises is presented with a photographical example as well as a video tutorial available at http://mantodearesearch.com. PMID:29200926

Distribution and habitat use of the Missouri River and Lower Yellowstone River benthic fishes from 1996 to 1998: A baseline for fish community recovery

Wildhaber, M.L.; Gladish, D.W.; Arab, A.

2011-01-01

Past and present Missouri River management practices have resulted in native fishes being identified as in jeopardy. In 1995, the Missouri River Benthic Fishes Study was initiated to provide improved information on Missouri River fish populations and how alterations might affect them. The study produced a baseline against which to evaluate future changes in Missouri River operating criteria. The objective was to evaluate population structure and habitat use of benthic fishes along the entire mainstem Missouri River, exclusive of reservoirs. Here we use the data from this study to provide a recent-past baseline for on-going Missouri River fish population monitoring programmes along with a more powerful method for analysing data containing large percentages of zero values. This is carried out by describing the distribution and habitat use of 21 species of Missouri River benthic fishes based on catch-per-unit area data from multiple gears. We employ a Bayesian zero-inflated Poisson model expanded to include continuous measures of habitat quality (i.e. substrate composition, depth, velocity, temperature, turbidity and conductivity). Along with presenting the method, we provide a relatively complete picture of the Missouri River benthic fish community and the relationship between their relative population numbers and habitat conditions. We demonstrate that our single model provides all the information that is often obtained by a myriad of analytical techniques. An important advantage of the present approach is reliable inference for patterns of relative abundance using multiple gears without using gear efficiencies.

Breech presentation occurs in 3 to 4% of all term pregnancies. External cephalic version (ECV) is proven effective to prevent vaginal breech deliveries and therefore it is recommended by clinical guidelines of the Royal Dutch Organisation for Midwives (KNOV) and the Dutch Society for Obstetrics and Gynaecology (NVOG). Implementation of ECV does not exceed 50 to 60% and probably less.We aim to improve the implementation of ECV to decrease maternal and neonatal morbidity and mortality due to breech presentations. This will be done by defining barriers and facilitators of implementation of ECV in the Netherlands. An innovative implementation strategy will be developed based on improved patient counselling and thorough instructions of health care providers for counselling. The ultimate purpose of this implementation study is to improve counselling of pregnant women and information of clinicians to realize a better implementation of ECV.The first phase of the project is to detect the barriers and facilitators of ECV. The next step is to develop an implementation strategy to inform and counsel pregnant women with a breech presentation, and to inform and educate care providers. In the third phase, the effectiveness of the developed implementation strategy will be evaluated in a randomised trial. The study population is a random selection of midwives and gynaecologists from 60 to 100 hospitals and practices. Primary endpoints are number of counselled women. Secondary endpoints are process indicators, the amount of fetes in cephalic presentation at birth, complications due to ECV, the number of caesarean sections and perinatal condition of mother and child. Cost effectiveness of the implementation strategy will be measured. This study will provide evidence for the cost effectiveness of a structural implementation of external cephalic versions to reduce the number of breech presentations at term.

Caring is a fundamental issue in the rehabilitation of a person with mental illness and more so for people with severe mental illness. The lack of adequate manpower resources in the country is adding and enlisting the responsibility of providing care on the families to provide physical, medical, social and psychological care for their severely unwell mentally ill people. To examine the load of caregiving with reference to the types of care during the symptomatic and remission phases of severe mental illness and the various ways in which caregivers adapt their lives to meet the needs of people with severe mental illness. The present research draws its data from the 200 families with mental illness in Andra Pradesh and Karnataka in India. The data presented in the study was collected from interviews using an interview schedule with open-ended questions. The study diffuses the notion of 'care' as 'physical', 'medical, 'psychological' and 'social' care. The present article focuses on the caregiving roles of the caregivers of people with schizophrenia, affective disorders and psychosis not otherwise specified (NOS) and found that the caregiving does not differ much between the different diagnosis, but caregiving roles changes from active involvement in physical and medical care to more of social and psychological care during the remission. The study records the incredulous gratitude of caregivers at being acknowledged for the work they do. In that regard, the study itself provides a boost to the morale of tired, unacknowledged caregivers.

The Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) is a multi-component epidemiological and neurobiological study designed to generate actionable evidence-based recommendations to reduce U.S. Army suicides and increase basic knowledge about the determinants of suicidality. This report presents an overview of the designs of the six component Army STARRS studies. These include: an integrated study of historical administrative data systems (HADS) designed to provide data on significant administrative predictors of suicides among the more than 1.6 million soldiers on active duty in 2004–2009; retrospective case-control studies of suicide attempts and fatalities; separate large-scale cross-sectional studies of new soldiers (i.e., those just beginning Basic Combat Training [BCT], who completed self-administered questionnaires [SAQ] and neurocognitive tests and provided blood samples) and soldiers exclusive of those in BCT (who completed SAQs); a pre-post deployment study of soldiers in three Brigade Combat Teams about to deploy to Afghanistan (who completed SAQs and provided blood samples) followed multiple times after returning from deployment; and a platform for following up Army STARRS participants who have returned to civilian life. DoD/Army administrative data records are linked with SAQ data to examine prospective associations between self-reports and subsequent suicidality. The presentation closes with a discussion of the methodological advantages of cross-component coordination. PMID:24318217

Why Do Pictures, but Not Visual Words, Reduce Older Adults’ False Memories?

PubMed Central

Smith, Rebekah E.; Hunt, R. Reed; Dunlap, Kathryn R.

2015-01-01

Prior work shows that false memories resulting from the study of associatively related lists are reduced for both young and older adults when the auditory presentation of study list words is accompanied by related pictures relative to when auditory word presentation is combined with visual presentation of the word. In contrast, young adults, but not older adults, show a reduction in false memories when presented with the visual word along with the auditory word relative to hearing the word only. In both the case of pictures relative to visual words and visual words relative to auditory words alone, the benefit of picture and visual words in reducing false memories has been explained in terms of monitoring for perceptual information. In our first experiment we provide the first simultaneous comparison of all three study presentation modalities (auditory only, auditory plus visual word, and auditory plus picture). Young and older adults show a reduction in false memories in the auditory plus picture condition, but only young adults show a reduction in the visual word condition relative to the auditory only condition. A second experiment investigates whether older adults fail to show a reduction in false memory in the visual word condition because they do not encode perceptual information in the visual word condition. In addition, the second experiment provides evidence that the failure of older adults to show the benefits of visual word presentation is related to reduced cognitive resources. PMID:26213799

This paper presents the results of an experimental investigation of two rotary-wing UAV designs. The primary goal of the investigation was to provide a set of interactional aerodynamic data for an emerging class of rotorcraft. The present paper provides an overview of the test and an introduction to the test articles, and instrumentation. Sample data in the form of a parametric study of fixed system lift and drag coefficient response to changes in configuration and flight condition for both rotor off and on conditions are presented. The presence of the rotor is seen to greatly affect both the character and magnitude of the response. The affect of scaled stores on body drag is observed to be dependent on body shape.

For undergraduate students, involvement in authentic research represents scholarship that is consistent with disciplinary quality standards and provides an integrative learning experience. In conjunction with performing research, the communication of the results via presentations or publications is a measure of the level of scientific engagement. The empirical study presented here uses generalized linear mixed models with hierarchical bootstrapping to examine the factors that impact the means of dissemination of undergraduate research results. Focusing on the research experiences in physics and chemistry of undergraduates at four Primarily Undergraduate Institutions (PUIs) from 2004-2013, statistical analysis indicates that the gender of the student does not impact the number and type of research products. However, in chemistry, the rank of the faculty advisor and the venue of the presentation do impact the number of research products by undergraduate student, whereas in physics, gender match between student and advisor has an effect on the number of undergraduate research products. This study provides a baseline for future studies of discipline-based bibliometrics and factors that affect the number of research products of undergraduate students.

2015-01-01

Background: Caring is a fundamental issue in the rehabilitation of a person with mental illness and more so for people with severe mental illness. The lack of adequate manpower resources in the country is adding and enlisting the responsibility of providing care on the families to provide physical, medical, social and psychological care for their severely unwell mentally ill people. Aim of the Study: To examine the load of caregiving with reference to the types of care during the symptomatic and remission phases of severe mental illness and the various ways in which caregivers adapt their lives to meet the needs of people with severe mental illness. Materials and Methods: The present research draws its data from the 200 families with mental illness in Andra Pradesh and Karnataka in India. The data presented in the study was collected from interviews using an interview schedule with open-ended questions. Results: The study diffuses the notion of ‘care’ as ‘physical’, ‘medical, ‘psychological’ and ‘social’ care. The present article focuses on the caregiving roles of the caregivers of people with schizophrenia, affective disorders and psychosis not otherwise specified (NOS) and found that the caregiving does not differ much between the different diagnosis, but caregiving roles changes from active involvement in physical and medical care to more of social and psychological care during the remission. Conclusion: The study records the incredulous gratitude of caregivers at being acknowledged for the work they do. In that regard, the study itself provides a boost to the morale of tired, unacknowledged caregivers. PMID:25969605

Patients hospitalized with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) engage in low levels of activity, putting them at risk for relapse and future readmissions. There is little direction for health care providers regarding the parameters for safe exercise during an AECOPD that is effective for increasing activity tolerance before discharge from hospital, especially for patients with associated comorbid conditions. To report the rationale for and methods of a study to develop evidence-informed care recommendations that guide health care providers in the assessment, prescription, monitoring and progression of exercise for patients hospitalized with AECOPD. The present study was a multicomponent knowledge translation project incorporating evidence from systematic reviews of exercise involving populations with chronic obstructive pulmonary disease and⁄or common comorbidities. A Delphi process was then used to obtain expert opinion from clinicians, academics and patients to identify the parameters of safe and effective exercise for patients with AECOPD. Clinical decision-making tool(s) for patients and practitioners supported by a detailed knowledge dissemination, implementation and evaluation framework. The present study addressed an important knowledge gap: the lack of availability of parameters to guide safe and effective exercise prescription for hospitalized patients with AECOPD, with or without comorbid conditions. In the absence of such parameters, health care professionals may adopt an 'activity as tolerated' approach, which may not improve physical activity levels in their patients. The present study synthesizes the best available evidence and expert opinion, and will generate decision-making tools for use by patients and their health care providers.

Leachables from pharmaceutical container closure systems can present potential safety risks to patients. Extractables studies may be performed as a risk mitigation activity to identify potential leachables for dosage forms with a high degree of concern associated with the route of administration. To address safety concerns, approaches to toxicological safety evaluation of extractables and leachables have been developed and applied by pharmaceutical and biologics manufacturers. Details of these approaches may differ depending on the nature of the final drug product. These may include application, the formulation, route of administration and length of use. Current regulatory guidelines and industry standards provide general guidance on compound specific safety assessments but do not provide a comprehensive approach to safety evaluations of leachables and/or extractables. This paper provides a perspective on approaches to safety evaluations by reviewing and applying general concepts and integrating key steps in the toxicological evaluation of individual extractables or leachables. These include application of structure activity relationship studies, development of permitted daily exposure (PDE) values, and use of safety threshold concepts. Case studies are provided. The concepts presented seek to encourage discussion in the scientific community, and are not intended to represent a final opinion or "guidelines." Copyright © 2016 Elsevier Inc.

Evolution as represented through argumentation: A qualitative study on reasoning and argumentation in high school biology teaching practices

NASA Astrophysics Data System (ADS)

Yalcinoglu, Pelin

This study aimed to explore high school biology teachers' epistemological criteria and their attention to reasoning and argumentation within their instructional practices. This study investigated: (1) what epistemological criteria do high school biology teachers use when justifying the validity of conclusions, (2) what is the frequency of the explicit use of reasoning and argumentation, if any, in high school biology teachers' instructional practices, and to what extend are reasoning and argumentation skills reflected, if at all, in high school biology teachers' modes of assessment. Three different data collection methods were employed in this study; face-to-face interviews, classroom observations, and document collections. Teachers' epistemological criteria were investigated to provide insight about their reasoning structures. This investigation was made possible by having teachers provide an argument about the validity of hypothetical conclusions drawn by the students based on two different scenarios related to evolution. Toulmin's Argument Pattern used to create rubric to analyze high school biology teachers' levels of reasoning through argumentation. Results of the data analysis suggested following findings. First, high school biology teachers participated in this study presented variety of epistemological criteria which were presented as high, moderate and low levels of reasoning through the argumentations. Second, elements of Toulmin's Argument Pattern were visible in the participants teaching practices, however students were not explicitly introduced to a well structured argument in those classrooms. High level of reasoning was not evident in the instructional practices of the observed teachers. High school biology classrooms which were observed in this study do not provide opportunities for students to practice high level of reasoning or improve their argumentation skills. Third, Interview Protocols designed for this study were found useful to identify the epistemological criteria and level of reasoning individuals presented through argumentation. Toulmin's Argument Pattern provides a practical method to analyze the structure of arguments. Results of this study suggest the following implications for improving science education. These implications might be helpful in increasing teacher awareness of the importance of explicit teaching of reasoning and argumentation in science classrooms. Toulmin's Argument Model should be introduced to teachers through teacher education or professional development programs to increase the use of reasoning and argumentation skills in instructional practices. Toulmin's Argument Pattern may be used to design lessons or unit plans which present science as argumentation. Therefore, by engaging students in argumentation, teachers may help students to improve their content knowledge along with reasoning and argumentation skills in science classrooms. The results of this study suggest that use of Toulmin's Argument Pattern to evaluate high school biology teachers' presented levels of reasoning is a promising approach to understanding the structure of reasoning and argumentation that biology teachers use when providing judgments about the validity of hypothetical conclusions. The interview protocols and the rubrics used in this study should be tested in different subject areas in order to enhance and validate the use of Toulmin's Argument Pattern in measuring individuals' epistemological criteria and level of reasoning.

Asking the difficult questions: message strategies used by organ procurement coordinators in requesting familial consent to organ donation.

PubMed

Anker, Ashley E; Feeley, Thomas Hugh

2011-07-01

The present study provides an in-depth examination of the messages used by organ procurement coordinators (OPCs) in shaping familial requests for organ donation. OPCs (N = 102), recruited from a national sample of 16 organ procurement organizations, participated in a structured interview designed to uncover the communication strategies used in obtaining familial consent for donation. Analysis of interviews indicates OPCs' messages cover 4 domain areas. Specifically, OPCs report use of messages intended to (a) provide education, (b) discuss the benefits to donation, (c) learn about potential donor families, and (d) persuade families to engage in donation. Within the 4 domain areas, OPCs report use of 15 specific messages (e.g., "positively framing the donor," "social proof," "discuss the benefit of donation to grieving") in requesting consent. The present study provides a detailed examination of strategies and offers recommendations for using message strategies to explore the effectiveness of the consent process from the perspective of OPCs in approaching donor families.

The study of ankylosing spondylitis (AS) has made significant progress over the last decade. Genome-wide association studies have identified and further substantiated the role of susceptibility genes outside the major histocompatibility complex locus. However, human leukocyte antigen (HLA)-B27 has been suggested to be important in the pathogenesis of AS, contributing to ~20.1% of AS heritability. The current review will present the classical and non-classical forms of HLA-B27, as well as their pathogenic roles, and further discuss the hypotheses regarding the potential pathogenesis of AS. In addition, the association between the pathogenic role of HLA-B27 and inflammatory indexes, including the interleukin-23/−17 axis will be investigated to provide novel insights into the pathogenesis of AS. The aim of the present review is to provide an update of the current research into the pathogenesis of AS, and provide a comprehensive description of the pathogenic role of HLA-B27 in AS.

Recently, integrated passive devices have become increasingly popular; inductor realization, in particular, offers interesting high performance for RF modules and systems. In this paper, a development of differential inductor fabricated by integrated passive devices technology using a double air-bridge structure is presented. A study of the model development of the differential inductor is first demonstrated. In this model section, a segment box analysis method is applied to provide a clear presentation of the differential inductor. Compared with other work that only shows a brief description of the process, the integrated passive devices process used to fabricate the inductor in this study is elaborated on. Finally, a characterization of differential inductors with different physical layout parameters is illustrated based on inductance and quality factors, which provides a valuable reference for realizing high performance. The proposed work provides a good solution for the design, fabrication and practical application of RF modules and systems.

2013-01-01

Behavioral economics is an emerging cross-disciplinary field that is providing an exciting new contextual framework for researchers to study addictive processes. New initiatives to study addiction under a behavioral economic rubric have yielded variable terminology and differing methods and theoretical approaches that are consistent with the multidimensional nature of addiction. The present article is intended to provide an integrative overview of the behavioral economic nomenclature and to describe relevant theoretical models, principles and concepts. Additionally, we present measures derived from behavioral economic theories that quantify demand for substances and assess decision making processes surrounding substance use. The sensitivity of these measures to different contextual elements (e.g., drug use status, acute drug effects, deprivation) is also addressed. The review concludes with discussion of the validity of these approaches and their potential for clinical application and highlights areas that warrant further research. Overall, behavioral economics offers a compelling framework to help explicate complex addictive processes and it is likely to provide a translational platform for clinical intervention.

Genital malodor in women: a modern reappraisal.

PubMed

Subramanian, Chithra; Nyirjesy, Paul; Sobel, Jack D

2012-01-01

Genital malodor is a common distressing complaint that brings a woman to her physician's office. Vaginal infections, primarily bacterial vaginosis and trichomoniasis, still remain the commonest causes and are relatively easy to diagnose and treat. However, in approximately one third of women who present with malodor, no cause is identified. Although data on the management of vaginal discharge are extensive, the management of genital odor beyond common vaginal infections remains poorly studied. This presents a frustrating situation for both the patient and her physician. Often, patients resort to home remedies and over-the-counter preparations, which, while providing short-term relief for some women, almost never address the cause and, in some cases, can exacerbate symptoms. In this review, we have attempted to consolidate the known and documented causes of genital malodor including the nonvaginal causes and provide case studies that will help clinicians understand the possible settings for the various causes. We also provide an algorithm for the management of this symptom beyond vaginal infections.

Prediction is Production: The missing link between language production and comprehension.

PubMed

Martin, Clara D; Branzi, Francesca M; Bar, Moshe

2018-01-18

Language comprehension often involves the generation of predictions. It has been hypothesized that such prediction-for-comprehension entails actual language production. Recent studies provided evidence that the production system is recruited during language comprehension, but the link between production and prediction during comprehension remains hypothetical. Here, we tested this hypothesis by comparing prediction during sentence comprehension (primary task) in participants having the production system either available or not (non-verbal versus verbal secondary task). In the primary task, sentences containing an expected or unexpected target noun-phrase were presented during electroencephalography recording. Prediction, measured as the magnitude of the N400 effect elicited by the article (expected versus unexpected), was hindered only when the production system was taxed during sentence context reading. The present study provides the first direct evidence that the availability of the speech production system is necessary for generating lexical prediction during sentence comprehension. Furthermore, these important results provide an explanation for the recruitment of language production during comprehension.

Increased capacity in future satellite systems can be achieved through antenna systems which provide multiplicity of frequency reuses at K sub a band. A number of antenna configurations which can provide multiple fixed spot beams and multiple independent spot scanning beams at 20 GHz are addressed. Each design incorporates a phased array with distributed MMIC amplifiers and phasesifters feeding a two reflector optical system. The tradeoffs required for the design of these systems and the corresponding performances are presented. Five final designs are studied. In so doing, a type of MMIC/waveguide transition is described, and measured results of the breadboard model are presented. Other hardware components developed are described. This includes a square orthomode transducer, a subarray fed with a beamforming network to measure scanning performance, and another subarray used to study mutual coupling considerations. Discussions of the advantages and disadvantages of the final design are included.

Columbus payload requirements in human physiology

NASA Astrophysics Data System (ADS)

Stegemann, Juergen

1993-03-01

Most of the biological feedback loops in the human body are interrelated. This means that several different parameters have to be recorded simultaneously to understand the interrelationship of different subsystems within the body when fast and slow adaptation processes are to be studied. This determines the requirements for the payload in the Columbus module. In 1988 ESA asked some European scientists in different fields of physiology to provide a 'science study' for the Columbus payload requirements. Their report was the basis of a phase A study completed in December 1991, concerning the 'ANTHROLAB', a laboratory that covers all presently known research challenges in this area. Anthrolab is more or less an improvement of the Anthrorack to be flown on the German Spacelab mission D-2 and on the Columbus precursor flight E-1. Beside the present Anthrorack design, Anthrolab will also provide subelements for vestibular, neurophysiological, and biomechanical research.

Information presentation format moderates the unconscious-thought effect: The role of recollection.

PubMed

Abadie, Marlène; Waroquier, Laurent; Terrier, Patrice

2016-09-01

The unconscious-thought effect occurs when distraction improves complex decision-making. In two experiments using the unconscious-thought paradigm, we investigated the effect of presentation format of decision information (i) on memory for decision-relevant information and (ii) on the quality of decisions made after distraction, conscious deliberation or immediately. We used the process-dissociation procedure to measure recollection and familiarity. The two studies showed that presenting information blocked per criterion led participants to recollect more decision-relevant details compared to a presentation by option. Moreover, a Bayesian meta-analysis of the two studies provided strong evidence that conscious deliberation resulted in better decisions when the information was presented blocked per criterion and substantial evidence that distraction improved decision quality when the information was presented blocked per option. Finally, Study 2 revealed that the recollection of decision-relevant details mediated the effect of presentation format on decision quality in the deliberation condition. This suggests that recollection contributes to conscious deliberation efficacy.

The Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) is a multi-component epidemiological and neurobiological study designed to generate actionable evidence-based recommendations to reduce US Army suicides and increase basic knowledge about the determinants of suicidality. This report presents an overview of the designs of the six components of the Army STARRS. These include: an integrated analysis of the Historical Administrative Data Study (HADS) designed to provide data on significant administrative predictors of suicides among the more than 1.6 million soldiers on active duty in 2004-2009; retrospective case-control studies of suicide attempts and fatalities; separate large-scale cross-sectional studies of new soldiers (i.e. those just beginning Basic Combat Training [BCT], who completed self-administered questionnaires [SAQs] and neurocognitive tests and provided blood samples) and soldiers exclusive of those in BCT (who completed SAQs); a pre-post deployment study of soldiers in three Brigade Combat Teams about to deploy to Afghanistan (who completed SAQs and provided blood samples) followed multiple times after returning from deployment; and a platform for following up Army STARRS participants who have returned to civilian life. Department of Defense/Army administrative data records are linked with SAQ data to examine prospective associations between self-reports and subsequent suicidality. The presentation closes with a discussion of the methodological advantages of cross-component coordination. Copyright © 2013 John Wiley & Sons, Ltd.

Privacy in image and video data has become an important subject since cameras are being installed in an increasing number of public and private spaces. Specifically, in assisted living, intelligent monitoring based on computer vision can allow one to provide risk detection and support services that increase people's autonomy at home. In the present work, a level-based visualisation scheme is proposed to provide visual privacy when human intervention is necessary, such as at telerehabilitation and safety assessment applications. Visualisation levels are dynamically selected based on the previously modelled context. In this way, different levels of protection can be provided, maintaining the necessary intelligibility required for the applications. Furthermore, a case study of a living room, where a top-view camera is installed, is presented. Finally, the performed survey-based evaluation indicates the degree of protection provided by the different visualisation models, as well as the personal privacy preferences and valuations of the users.

Encryption method based on pseudo random spatial light modulation for single-fibre data transmission

NASA Astrophysics Data System (ADS)

Kowalski, Marcin; Zyczkowski, Marek

2017-11-01

Optical cryptosystems can provide encryption and sometimes compression simultaneously. They are increasingly attractive for information securing especially for image encryption. Our studies shown that the optical cryptosystems can be used to encrypt optical data transmission. We propose and study a new method for securing fibre data communication. The paper presents a method for optical encryption of data transmitted with a single optical fibre. The encryption process relies on pseudo-random spatial light modulation, combination of two encryption keys and the Compressed Sensing framework. A linear combination of light pulses with pseudo-random patterns provides a required encryption performance. We propose an architecture to transmit the encrypted data through the optical fibre. The paper describes the method, presents the theoretical analysis, design of physical model and results of experiment.

Duke, J. C., Jr.; Henneke, E. G., II; Kiernan, M. T.; Grosskopf, P. P.

1989-01-01

The acousto-ultrasonic approach for nondestructive evaluation provides a measurement procedure for quantifying the integrated effect of globally distributed damage characteristic of fiber reinforced composite materials. The evaluation procedure provides a stress wave factor that correlates closely with several material performance parameters. The procedure was investigated for a variety of materials including advanced composites, hybrid structure bonds, adhesive bonds, wood products, and wire rope. The research program focused primarily on development of fundamental understanding and applications advancements of acousto-ultrasonics for materials characterization. This involves characterization of materials for which detection, location, and identification of imperfections cannot at present be analyzed satisfactorily with mechanical performance prediction models. In addition to presenting definitive studies on application potentials, the understanding of the acousto-ultrasonic method as applied to advanced composites is reviewed.

In an effort to improve the physiologic relevance of existing in vitro models for alveolar cells, we present a microfluidic platform which provides an air-interface in a dynamic system combining microfluidic and suspended membrane culture systems. Such a system provides the ability to manipulate multiple parameters on a single platform along with ease in cell seeding and manipulation. The current study presents a comparison of the efficacy of the hybrid system with conventional platforms using assays analyzing the maintenance of function and integrity of A549 alveolar epithelial cell monolayer cultures. The hybrid system incorporates bio-mimetic nourishment on the basal side of the epithelial cells along with an open system on the apical side of the cells exposed to air allowing for easy access for assays.

Many features of auditory perception are positively altered in musicians. Traditionally auditory mechanisms in musicians are investigated using the Western-classical musician model. The objective of the present study was to adopt an alternative model-Indian-classical music-to further investigate auditory temporal processing in musicians. This study presents that musicians have significantly lower across-channel gap detection thresholds compared to nonmusicians. Use of the South Indian musician model provides an increased external validity for the prediction, from studies on Western-classical musicians, that auditory temporal coding is enhanced in musicians.

Vocal reaction times to unilaterally presented concrete and abstract words: towards a theory of differential right hemispheric semantic processing.

PubMed

Rastatter, M; Dell, C W; McGuire, R A; Loren, C

1987-03-01

Previous studies investigating hemispheric organization for processing concrete and abstract nouns have provided conflicting results. Using manual reaction time tasks some studies have shown that the right hemisphere is capable of analyzing concrete words but not abstract. Others, however, have inferred that the left hemisphere is the sole analyzer of both types of lexicon. The present study tested these issues further by measuring vocal reaction times of normal subjects to unilaterally presented concrete and abstract items. Results were consistent with a model of functional localization which suggests that the minor hemisphere is capable of differentially processing both types of lexicon in the presence of a dominant left hemisphere.

Which instructor qualities do students consider most important? The answer likely depends on the student. This study attempted to trace beliefs about the most essential instructor qualities to students' academic achievement goals. The present study tested the hypothesis that students pursuing mastery goals favour instructors who stimulate and challenge them intellectually, whereas those pursuing performance goals favour instructors who present material clearly and provide clear cues about how to succeed. Participants were 157 students at a 4-year public university. Participants designed the ideal professor through a hypothetical combination of nine widely valued instructor qualities, such as enthusiasm, presentation clarity, and an interactive teaching style. The more they acquired of any one instructor quality, the less they could acquire of the others, thus compelling students to distinguish necessary qualities from desirable luxury qualities. Students' achievement goals corresponded to their views about the most essential instructor qualities. Mastery goals predicted greater demand for professors who intellectually challenge students and possess topic expertise, whereas performance goals predicted high demand for professors who present material clearly and provide cues about how to succeed in the course. The findings support emerging theorizing about how mastery and performance goals nudge students to pursue different learning agendas, with distinct consequences to their learning experience. ©2011 The British Psychological Society.

Heuristics for connectivity-based brain parcellation of SMA/pre-SMA through force-directed graph layout.

PubMed

Crippa, Alessandro; Cerliani, Leonardo; Nanetti, Luca; Roerdink, Jos B T M

2011-02-01

We propose the use of force-directed graph layout as an explorative tool for connectivity-based brain parcellation studies. The method can be used as a heuristic to find the number of clusters intrinsically present in the data (if any) and to investigate their organisation. It provides an intuitive representation of the structure of the data and facilitates interactive exploration of properties of single seed voxels as well as relations among (groups of) voxels. We validate the method on synthetic data sets and we investigate the changes in connectivity in the supplementary motor cortex, a brain region whose parcellation has been previously investigated via connectivity studies. This region is supposed to present two easily distinguishable connectivity patterns, putatively denoted by SMA (supplementary motor area) and pre-SMA. Our method provides insights with respect to the connectivity patterns of the premotor cortex. These present a substantial variation among subjects, and their subdivision into two well-separated clusters is not always straightforward. Copyright © 2010 Elsevier Inc. All rights reserved.

Glaciological studies in the central Andes using AIRSAR/TOPSAR

Forster, Richard R.; Klein, Andrew G.; Blodgett, Troy A.; Isacks, Bryan L.

1993-01-01

The interaction of climate and topography in mountainous regions is dramatically expressed in the spatial distribution of glaciers and snowcover. Monitoring existing alpine glaciers and snow extent provides insight into the present mountain climate system and how it is changing, while mapping the positions of former glaciers as recorded in landforms such as cirques and moraines provide a record of the large past climate change associated with the last glacial maximum. The Andes are an ideal mountain range in which to study the response of snow and ice to past and present climate change. Their expansive latitudinal extent offers the opportunity to study glaciers in diverse climate settings from the tropical glaciers of Peru and Bolivia to the ice caps and tide-water glaciers of sub-polar Patagonia. SAR has advantages over traditional passive remote sensing instruments for monitoring present snow and ice and differentiating moraine relative ages. The cloud penetrating ability of SAR is indispensable for perennially cloud covered mountains. Snow and ice facies can be distinguished from SAR's response to surface roughness, liquid water content and grain size distribution. The combination of SAR with a coregestered high-resolution DEM (TOPSAR) provides a promising tool for measuring glacier change in three dimensions, thus allowing ice volume change to be measured directly. The change in moraine surface roughness over time enables SAR to differentiate older from younger moraines. Polarimetric SAR data have been used to distinguish snow and ice facies and relatively date moraines. However, both algorithms are still experimental and require ground truth verification. We plan to extend the SAR classification of snow and ice facies and moraine age beyond the ground truth sites to throughout the Cordillera Real to provide a regional view of past and present snow and ice. The high resolution DEM will enhance the SAR moraine dating technique by discriminating relative ages based on moraine slope degradation.

To (a) identify post-concussion symptom scales appropriate for children and adolescents in sports; (b) review evidence for reliability and validity; and (c) recommend future directions for scale development. Quantitative and qualitative literature review of symptom rating scales appropriate for children and adolescents aged 5 to 22 years. Literature identified via search of Medline, Ovid-Medline and PsycInfo databases; review of reference lists in identified articles; querying sports concussion specialists. 29 articles met study inclusion criteria. 5 symptom scales examined in 11 studies for ages 5-12 years and in 25 studies for ages 13-22. 10 of 11 studies for 5-12-year-olds presented validity evidence for three scales; 7 studies provided reliability evidence for two scales; 7 studies used serial administrations but no reliable change metrics. Two scales included parent-reports and one included a teacher report. 24 of 25 studies for 13-22 year-olds presented validity evidence for five measures; seven studies provided reliability evidence for four measures with 18 studies including serial administrations and two examining Reliable Change. Psychometric evidence for symptom scales is stronger for adolescents than for younger children. Most scales provide evidence of concurrent validity, discriminating concussed and non-concussed groups. Few report reliability and evidence for validity is narrow. Two measures include parent/teacher reports. Few scales examine reliable change statistics, limiting interpretability of temporal changes. Future studies are needed to fully define symptom scale psychometric properties with the greatest need in younger student-athletes.

Endothelial progenitor cells (EPCs) are currently being studied as candidate cell sources for revascularization strategies. Significant advances have been made in understanding the biology of EPCs, and preclinical studies have demonstrated the vasculogenic, angiogenic, and beneficial paracrine effects of transplanted EPCs in the treatment of ischemic diseases. Despite these promising results, widespread clinical acceptance of EPCs for clinical therapies remains hampered by several challenges. The present study provides a concise summary of the different EPC populations being studied for ischemic therapies and their known roles in the healing of ischemic tissues. The challenges and issues surrounding the use of EPCs and the current strategies being developed to improve the harvest efficiency and functionality of EPCs for application in regenerative medicine are discussed. Significance Endothelial progenitor cells (EPCs) have immense clinical value for cardiovascular therapies. The present study provides a concise description of the EPC subpopulations being evaluated for clinical applications. The current major lines of investigation involving preclinical and clinical evaluations of EPCs are discussed, and significant gaps limiting the translation of EPCs are highlighted. The present report could be useful for clinicians and clinical researchers with interests in ischemic therapy and for basic scientists working in the related fields of tissue engineering and regenerative medicine.

Usability Evaluation of a Flight-Deck Airflow Hazard Visualization System

NASA Technical Reports Server (NTRS)

Aragon, Cecilia R.

2004-01-01

Many aircraft accidents each year are caused by encounters with unseen airflow hazards near the ground, such as vortices, downdrafts, low level wind shear, microbursts, or turbulence from surrounding vegetation or structures near the landing site. These hazards can be dangerous even to airliners; there have been hundreds of fatalities in the United States in the last two decades attributable to airliner encounters with microbursts and low level wind shear alone. However, helicopters are especially vulnerable to airflow hazards because they often have to operate in confined spaces and under operationally stressful conditions (such as emergency search and rescue, military or shipboard operations). Providing helicopter pilots with an augmented-reality display visualizing local airflow hazards may be of significant benefit. However, the form such a visualization might take, and whether it does indeed provide a benefit, had not been studied before our experiment. We recruited experienced military and civilian helicopter pilots for a preliminary usability study to evaluate a prototype augmented-reality visualization system. The study had two goals: first, to assess the efficacy of presenting airflow data in flight; and second, to obtain expert feedback on sample presentations of hazard indicators to refine our design choices. The study addressed the optimal way to provide critical safety information to the pilot, what level of detail to provide, whether to display specific aerodynamic causes or potential effects only, and how to safely and effectively shift the locus of attention during a high-workload task. Three-dimensional visual cues, with varying shape, color, transparency, texture, depth cueing, and use of motion, depicting regions of hazardous airflow, were developed and presented to the pilots. The study results indicated that such a visualization system could be of significant value in improving safety during critical takeoff and landing operations, and also gave clear indications of the best design choices in producing the hazard visual cues.

2013-07-01

The aim of this study is supporting the conceptual discussions of architectural restoration with three dimensional modeling of monuments based on photogrammetric survey. In this study, a 16th century village bath in Ulamış, Seferihisar, and Izmir is modeled for documentation. Ulamış is one of the historical villages within which Turkish population first settled in the region of Seferihisar - Urla. The methodology was tested on an antique monument; a bath with a cubical form. Within the limits of this study, only the exterior of the bath was modeled. The presentation scale for the bath was determined as 1 / 50, considering the necessities of designing structural interventions and architectural ones within the scope of a restoration project. The three dimensional model produced is a realistic document presenting the present situation of the ruin. Traditional plan, elevation and perspective drawings may be produced from the model, in addition to the realistic textured renderings and wireframe representations. The model developed in this study provides opportunity for presenting photorealistic details of historical morphologies in scale. Compared to conventional drawings, the renders based on the 3d models provide an opportunity for conceiving architectural details such as color, material and texture. From these documents, relatively more detailed restitution hypothesis can be developed and intervention decisions can be taken. Finally, the principles derived from the case study can be used for 3d documentation of historical structures with irregular surfaces.

The present study evaluated a Swiss internet provider of Evidence-based Medicine (EBM) with regard to its utilization and function for medical practitioners. The internet provider under study (www.evimed.ch) primarily provides abstracts of original articles relevant to medical practice that are presented according to the criteria of EBM and includes information about EBM itself. In March 1999 a survey was conducted to better appraise the benefits gained from the information provided from the website visitors' point of view. Around 400 persons who had entered their names in the homepage guest book were informed about the survey by e-mail. A total of 167 questionnaires were filled in online, which is equivalent to the reply rate of close to 42%. The majority of the replies (63.5%) were from private-practice physicians, 22.2% from hospital-based physicians. The average age ranged between 40 and 49 years. 67.7% of the 167 respondents had internet access at their workplace, 72.5% had private internet access. For their own practical work, 61.1% of the respondents rated the information provided by www.evimed.ch as generally useful. The clinical relevance of the studies presented in the Journal Club was rated as good by 55.7% and as very good by 26.9%. The reliability of the information provided was rated as good by 56.3% and as very good by 35.3%. The majority regarded the following homepage sites as personally important: Journal Club (55.7%), articles about EBM (46.1%), MEDLINE access (37.7%) and article citations/links (41.3%). The homepage was visited at an average frequency of 1-3 times a month. 50.3% preferred electronic media (40.1% using various internet providers, 10.2% www.evimed.ch) and 44.3% preferred print media to search for specialist information on a specific medical subject. With regard to new medical findings, 44.9% of the respondents stated that they used print media, 17.4% the www.evimed.ch homepage and 28.7% other internet sources as their primary information medium. Based on this survey, the majority of the respondents gave a positive rating of the www.evimed.ch homepage. Information about EBM and critically appraised studies were evaluated as particularly useful.

Nakanishi, Miharu; Niimura, Junko; Nishida, Atsushi

2017-06-01

Home-visit nursing-care services in Japan are expected to provide home hospice services for older patients with non-cancer diseases. The aim of the present study was to examine factors that contribute to the provision of end-of-life care by home-visit nursing-care providers in Japan. The present retrospective study was carried out using nationally representative cross-sectional data from the 2007, 2010, and 2013 Survey of Institutions and Establishments for Long-Term Care. A total of 138 008 randomly sampled home-visit nursing-care service users were included in this analysis. End-of-life care (study outcome) was defined as the provision of nursing-care within the last month of life. Of the 138 008 patients at home, 2280 (1.7%) received home-based nursing care within the last month of life, and end-of-life care was offered primarily to cancer patients (n = 1651; 72.4%). After accounting for patient characteristics, patients were more likely to receive end-of-life care when they used home-visit nursing-care providers that had a greater number of nursing staff or were located in a region with fewer hospital beds. Among home-visit nursing-care providers, the nursing staff ratio and the availability of hospital beds were related to the provision of end-of-life care. Home-visit nursing-care providers should establish specialist hospice care teams with enhanced staffing ratios to allow for the adequate provision of home-based end-of-life care. A community-based network between home-visit nursing-care providers and hospitals should also be established to attain an integrated end-of-life care system for elderly populations in regions with more hospital beds.

PubMed

Sandoval-Rincón, Maritza; Sáenz-Farret, Michel; Miguel-Puga, Adán; Micheli, Federico; Arias-Carrión, Oscar

2015-01-01

Parkinson's disease (PD) is not a single entity but rather a heterogeneous neurodegenerative disorder. The present study aims to conduct a critical systematic review of the literature to describe the main pharmacological strategies to treat cognitive dysfunction and major depressive disorder in PD patients. We performed a search of articles cited in PubMed from 2004 to 2014 using the following MeSH terms (Medical subject headings) "Parkinson disease"; "Delirium," "Dementia," "Amnestic," "Cognitive disorders," and "Parkinson disease"; "depression," "major depressive disorder," "drug therapy." We found a total of 71 studies related to pharmacological treatment in cognitive dysfunction and 279 studies for pharmacological treatment in major depressive disorder. After fulfillment of all the inclusion and exclusion criteria, 13 articles remained for cognitive dysfunction and 11 for major depressive disorder, which are presented and discussed in this study. Further research into non-motor symptoms of PD may provide insights into mechanisms of neurodegeneration, and provide better quality of life by using rational drugs.

2015-12-01

Satellite remote sensing of the environment offers a unique vantage point that can fill in the gaps of environmental, spatial, and temporal data for tracking disease. Health and Air Quality providers and researchers are effective by the global environmental changes that are occurring and they need environmental data to study and understand the geographic, environmental, and meteorological differences in disease. This presentation maintains a diverse constellation of Earth observing research satellites and sponsors research in developing satellite data applications across a wide spectrum of areas including environmental health; infectious disease; air quality standards, policies, and regulations; and the impact of climate change on health and air quality. Successfully providing predictions with the accuracy and specificity required by decision makers will require advancements over current capabilities in a number of interrelated areas. These areas include observations, modeling systems, forecast development, application integration, and the research to operations transition process. This presentation will highlight many projects on which NASA satellites have been a primary partner with local, state, Federal, and international operational agencies over the past twelve years in these areas. Domestic and International officials have increasingly recognized links between environment and health. Health providers and researchers need environmental data to study and understand the geographic, environmental, and meteorological differences in disease. The presentation is directly related to Earth Observing systems and Global Health Surveillance and will present research results of the remote sensing environmental observations of earth and health applications, which can contribute to the health research. As part of NASA approach and methodology they have used Earth Observation Systems and Applications for Health Models to provide a method for bridging gaps of environmental, spatial, and temporal data for tracking disease.

Hemer, Mark; Dobrynin, Mikhail; Erikson, Li; Lionello, Piero; Mori, Nobuhito; Semedo, Alvaro; Wang, Xiaolan

2016-04-01

Future 21st Century changes in wind-wave climate have broad implications for marine and coastal infrastructure and ecosystems. Atmosphere-ocean general circulation models (GCM) are now routinely used for assessing and providing future projections of climatological parameters such as temperature and precipitation, but generally these provide no information on ocean wind-waves. To fill this information gap a growing number of studies are using GCM outputs and independently producing global and regional scale wind-wave climate projections. Furthermore, additional studies are actively coupling wind-wave dependent atmosphere-ocean exchanges into GCMs, to improve physical representation and quantify the impact of waves in the coupled climate system, and can also deliver wave characteristics as another variable in the climate system. To consolidate these efforts, understand the sources of variance between projections generated by different methodologies and International groups, and ultimately provide a robust picture of the role of wind-waves in the climate system and their projected changes, we present outcomes of the JCOMM supported Coordinated Ocean Wave Climate Project (COWCLIP). The objective of COWCLIP is twofold: to make community based ensembles of wave climate projections openly accessible, to provide the necessary information to support diligent marine and coastal impacts of climate change studies; and to understand the effects and feedback influences of wind-waves in the coupled ocean-atmosphere climate system. We will present the current status of COWCLIP, providing an overview of the objectives, analysis and results of the initial phase - now complete - and the progress of ongoing phases of the project.

Insect-inspired wing actuation structures based on ring-type resonators

NASA Astrophysics Data System (ADS)

Bolsman, Caspar T.; Goosen, Johannes F. L.; van Keulen, Fred

2008-03-01

In this paper, we illustrate and study the opportunities of resonant ring type structures as wing actuation mechanisms for a flapping wing Micro Air Vehicle (MAV). Various design alternatives are presented and studied based on computational and physical models. Insects provide an excellent source of inspiration for the development of the wing actuation mechanisms for flapping wing MAVs. The insect thorax is a structure which in essence provides a mechanism to couple the wing muscles to the wings while offering weight reduction through application of resonance, using tailored elasticity. The resonant properties of the thorax are a very effective way to reducing the power expenditure of wing movement. The wing movement itself is fairly complex and is guided by a set of control muscles and thoracic structures which are present in proximity of the wing root. The development of flapping wing MAVs requires a move away from classical structures and actuators. The use of gears and rotational electric motors is hard to justify at the small scale. Resonant structures provide a large design freedom whilst also providing various options for actuation. The move away from deterministic mechanisms offers possibilities for mass reduction.

Cell refractive index for cell biology and disease diagnosis: past, present and future.

Cell refractive index is a key biophysical parameter, which has been extensively studied. It is correlated with other cell biophysical properties including mechanical, electrical and optical properties, and not only represents the intracellular mass and concentration of a cell, but also provides important insight for various biological models. Measurement techniques developed earlier only measure the effective refractive index of a cell or a cell suspension, providing only limited information on cell refractive index and hence hindering its in-depth analysis and correlation. Recently, the emergence of microfluidic, photonic and imaging technologies has enabled the manipulation of a single cell and the 3D refractive index of a single cell down to sub-micron resolution, providing powerful tools to study cells based on refractive index. In this review, we provide an overview of cell refractive index models and measurement techniques including microfluidic chip-based techniques for the last 50 years, present the applications and significance of cell refractive index in cell biology, hematology, and pathology, and discuss future research trends in the field, including 3D imaging methods, integration with microfluidics and potential applications in new and breakthrough research areas.

According to the World Health Organization, up to 90% of population in developing countries use plants and its products as traditional medicine for primary health care. There are about 800 plants which have been reported to show antidiabetic potential. The present review is aimed at providing in-depth information about the antidiabetic potential and bioactive compounds present in Ficus religiosa, Pterocarpus marsupium, Gymnema sylvestre, Allium sativum, Eugenia jambolana, Momordica charantia, and Trigonella foenum-graecum. The review provides a starting point for future studies aimed at isolation, purification, and characterization of bioactive antidiabetic compounds present in these plants. PMID:23841105

Nonequilibrium Stagnation-Line Radiative Heating for Fire II

NASA Technical Reports Server (NTRS)

Johnston, Christopher O.; Hollis, Brian R.; Sutton, Kenneth

2007-01-01

This paper presents a detailed analysis of the shock-layer radiative heating to the Fire II vehicle using a new air radiation model and a viscous shock-layer flowfield model. This new air radiation model contains the most up-to-date properties for modeling the atomic-line, atomic photoionization, molecular band, and non-Boltzmann processes. The applied viscous shock-layer flowfield analysis contains the same thermophysical properties and nonequilibrium models as the LAURA Navier-Stokes code. Radiation-flowfield coupling, or radiation cooling, is accounted for in detail in this study. It is shown to reduce the radiative heating by about 30% for the peak radiative heating points, while reducing the convective heating only slightly. A detailed review of past Fire II radiative heating studies is presented. It is observed that the scatter in the radiation predicted by these past studies is mostly a result of the different flowfield chemistry models and the treatment of the electronic state populations. The present predictions provide, on average throughout the trajectory, a better comparison with Fire II flight data than any previous study. The magnitude of the vacuum ultraviolet (VUV) contribution to the radiative flux is estimated from the calorimeter measurements. This is achieved using the radiometer measurements and the predicted convective heating. The VUV radiation predicted by the present model agrees well with the VUV contribution inferred from the Fire II calorimeter measurement, although only when radiation-flowfield coupling is accounted for. This agreement provides evidence that the present model accurately models the VUV radiation, which is shown to contribute significantly to the Fire II radiative heating.

Multiscale Documentation and Monitoring of L'aquila Historical Centre Using Uav Photogrammetry

NASA Astrophysics Data System (ADS)

Dominici, D.; Alicandro, M.; Rosciano, E.; Massimi, V.

2017-05-01

Nowadays geomatic techniques can guarantee not only a precise and accurate survey for the documentation of our historical heritage but also a solution to monitor its behaviour over time after, for example, a catastrophic event (earthquakes, landslides, ecc). Europe is trying to move towards harmonized actions to store information on cultural heritage (MIBAC with the ICCS forms, English heritage with the MIDAS scheme, etc) but it would be important to provide standardized methods in order to perform measuring operations to collect certified metric data. The final result could be a database to support the entire management of the cultural heritage and also a checklist of "what to do" and "when to do it". The wide range of geomatic techniques provides many solutions to acquire, to organize and to manage data at a multiscale level: high resolution satellite images can provide information in a short time during the "early emergency" while UAV photogrammetry and laser scanning can provide digital high resolution 3D models of buildings, ortophotos of roofs and facades and so on. This paper presents some multiscale survey case studies using UAV photogrammetry: from a minor historical village (Aielli) to the centre of L'Aquila (Santa Maria di Collemaggio Church) from the post-emergency to now. This choice has been taken not only to present how geomatics is an effective science for modelling but also to present a complete and reliable way to perform conservation and/or restoration through precise monitoring techniques, as shown in the third case study.

2018-01-01

Domestic violence (DV) can threaten women's health. Healthcare providers (HCPs) may be the first to come into contact with a victim of DV. Their appropriate performance regarding a DV victim can decrease its complications. The aim of the present study was to investigate HCPs' performance regarding women experiencing DV in emergency and maternity wards of hospitals in Isfahan, Iran. The present descriptive, cross-sectional study was conducted among 300 HCPs working in emergency and maternity wards in hospitals in Isfahan. The participants were selected using quota random sampling from February to May 2016. A researcher-made questionnaire containing the five items of HCPs performance regarding DV (assessment, intervention, documentation, reference, and follow-up) was used to collect data. The reliability and validity of the questionnaire were confirmed, and the collected data were analyzed using SPSS software. Cronbach's alpha was used to assess the reliability of the questionnaires. To present a general description of the data (variables, mean, and standard deviation), the table of frequencies was designed. The performance of the participants regarding DV in the assessment (mean = 64.22), intervention (mean = 68.55), and reference stages (mean = 68.32) were average. However, in the documentation (mean = 72.55) and follow-up stages (mean = 23.10), their performance was good and weak respectively (criterion from 100). Based on the results, because of defects in providing services for women experiencing DV, a practical indigenous guideline should be provided to treat and support these women.

Faster, cheaper sequencing technologies and the ability to sequence uncultured microbes sampled directly from their habitats are expanding and transforming our view of the microbial world. Distilling meaningful information from the millions of new genomic sequences presents a serious challenge to bioinformaticians. In cultured microbes, the genomic data come from a single clone, making sequence assembly and annotation tractable. In metagenomics, the data come from heterogeneous microbial communities, sometimes containing more than 10,000 species, with the sequence data being noisy and partial. From sampling, to assembly, to gene calling and function prediction, bioinformatics faces new demands in interpreting voluminous, noisy, and often partial sequence data. Although metagenomics is a relative newcomer to science, the past few years have seen an explosion in computational methods applied to metagenomic-based research. It is therefore not within the scope of this article to provide an exhaustive review. Rather, we provide here a concise yet comprehensive introduction to the current computational requirements presented by metagenomics, and review the recent progress made. We also note whether there is software that implements any of the methods presented here, and briefly review its utility. Nevertheless, it would be useful if readers of this article would avail themselves of the comment section provided by this journal, and relate their own experiences. Finally, the last section of this article provides a few representative studies illustrating different facets of recent scientific discoveries made using metagenomics. PMID:20195499

A study conducted as part of the development of the Eleventh International Classification of Mental Disorders for Primary Health Care (ICD-11 PHC) provided an opportunity to test the relationships among depressive, anxious and somatic symptoms in PHC. Primary care physicians participating in the ICD-11 PHC field studies in five countries selected patients who presented with somatic symptoms not explained by known physical pathology by applying a 29-item screening on somatic complaints that were under study for bodily stress disorder. Patients were interviewed using the Clinical Interview Schedule-Revised and assessed using two five-item scales that measure depressive and anxious symptoms. Structural models of anxious-depressive symptoms and somatic complaints were tested using a bi-factor approach. A total of 797 patients completed the study procedures. Two bi-factor models fit the data well: Model 1 had all symptoms loaded on a general factor, along with one of three specific depression, anxiety and somatic factors [x2 (627) = 741.016, p < 0.0011, RMSEA = 0.015, CFI = 0.911, TLI = 0.9]. Model 2 had a general factor and two specific anxious depression and somatic factors [x2 (627) = 663.065, p = 0.1543, RMSEA = 0.008, CFI = 0.954, TLI = 0.948]. These data along with those of previous studies suggest that depressive, anxious and somatic symptoms are largely different presentations of a common latent phenomenon. This study provides support for the ICD-11 PHC conceptualization of mood disturbance, especially anxious depression, as central among patients who present multiple somatic symptoms.

There is growing interest in the effect of sound on visual motion perception. One model involves the illusion created when two identical objects moving towards each other on a two-dimensional visual display can be seen to either bounce off or stream through each other. Previous studies show that the large bias normally seen toward the streaming percept can be modulated by the presentation of an auditory event at the moment of coincidence. However, no reports to date provide sufficient evidence to indicate whether the sound bounce-inducing effect is due to a perceptual binding process or merely to an explicit inference resulting from the transient auditory stimulus resembling a physical collision of two objects. In the present study, we used a novel experimental design in which a subliminal sound was presented either 150 ms before, at, or 150 ms after the moment of coincidence of two disks moving towards each other. The results showed that there was an increased perception of bouncing (rather than streaming) when the subliminal sound was presented at or 150 ms after the moment of coincidence compared to when no sound was presented. These findings provide the first empirical demonstration that activation of the human auditory system without reaching consciousness affects the perception of an ambiguous visual motion display.

This paper aims to present a method of volumetric verification in machine tools with linear and rotary axes using a laser tracker. Beyond a method for a particular machine, it presents a methodology that can be used in any machine type. Along this paper, the schema and kinematic model of a machine with three axes of movement, two linear and one rotational axes, including the measurement system and the nominal rotation matrix of the rotational axis are presented. Using this, the machine tool volumetric error is obtained and nonlinear optimization techniques are employed to improve the accuracy of the machine tool. The verification provides a mathematical, not physical, compensation, in less time than other methods of verification by means of the indirect measurement of geometric errors of the machine from the linear and rotary axes. This paper presents an extensive study about the appropriateness and drawbacks of the regression function employed depending on the types of movement of the axes of any machine. In the same way, strengths and weaknesses of measurement methods and optimization techniques depending on the space available to place the measurement system are presented. These studies provide the most appropriate strategies to verify each machine tool taking into consideration its configuration and its available work space. PMID:25202744

After several years of proof-of-principle measurements and focus on technological development, it is timely to make full use of the capabilities of CARS microscopy within the biosciences. We have here identified an urgent biological problem, to which CARS microscopy provides unique insights and consequently may become a widely accepted experimental procedure. In order to improve present understanding of mechanisms underlying dysfunctional metabolism regulation reported for many of our most wide-spread diseases (obesity, diabetes, cardio-vascular diseases etc.), we have monitored genetic and environmental impacts on cellular lipid storage in the model organism C. elegans in vivo in a full-scale biological study. Important advantages of CARS microscopy could be demonstrated compared to present technology, i.e. fluorescence microscopy of labelled lipid stores. The fluorescence signal varies not only with the presence of lipids, but also with the systemic distribution of the fluorophore and the chemical properties of the surrounding medium. By instead probing high-density regions of CH bonds naturally occurring in the sample, the CARS process was shown to provide a consistent representation of the lipid stores. The increased accumulation of lipid stores in mutants with deficiencies in the insulin and transforming growth factor signalling pathways could hereby be visualized and quantified. Furthermore, spectral CARS microscopy measurements in the C-H bond region of 2780-2930 cm -1 provided the interesting observation that this accumulation comes with a shift in the ordering of the lipids from gel- to liquid phase. The present study illustrates that CARS microscopy has a strong potential to become an important instrument for systemic studies of lipid storage mechanisms in living organisms, providing new insights into the phenomena underlying metabolic disorders.

Understanding volcanic geomorphology from derivatives and wavelet analysis: A case study at Miyakejima Volcano, Izu Islands, Japan

From feature recognition to multiscale analysis, the human brain does this computation almost instantaneously, but reproducing this process for effective computation is still a challenge. Although it is a growing field in computational geomorphology, there has been only limited investigation of those issues on volcanoes. For the present study, we investigated Miyakejima, a volcanic island in the Izu archipelago, located 200 km south of Tokyo City (Japan). The island has experienced numerous Quaternary and historical eruptions, which have been recorded in details and therefore provide a solid foundation to experiment remote-sensing methods and compare the results to existing data. In the present study, the author examines the use of DEM derivatives and wavelet decomposition 5 m DEM available from the Geographic Authority of Japan was used. It was pre-processed to generate grid data with QGIS. The data was then analyzed with remote sensing techniques and wavelet analysis in ENVI and Matlab. Results have shown that the combination of 'Elevation' with 'Local Data Range Variation' and 'Relief Mapping' as a RGB image composite provides a powerful visual interpretation tool, but the feature separation remains a subjective analysis provided a more appropriate dataset for computer-based analysis and information extraction and understanding of topographic features at different scales. In order to confirm the usefulness of these topographic derivatives, the results were compared to known geological features and it was found to be in accordance with the data provided by geological, topographic maps and field research at Miyakejima. The protocol presented in the discussion can therefore be re-used at other volcanoes worldwide where less information is available on past-eruption and geology, in order to explain the volcanic geomorphology.

Development of FEA Models to Study Contusion Patterning in Layered Tissue and the Shaft Loaded Blister Test

Giuffre, Christopher James

In the natural world there is no such thing as a perfectly sharp edge, either thru wear or machining imprecation at the macroscopic scale all edges have curvature. This curvature can have significant impact when comparing results with theory. Both numerical and analytic models for the contact of an object with a sharp edge predict infinite stresses which are not present in the physical world. It is for this reason that the influence of rounded edges must be studied to better understand how they affect model response. Using a commercial available finite element package this influence will be studied in two different problems; how this edge geometry effects the shape of a contusion (bruise) and the accuracy of analytic models for the shaft loaded blister test (SLBT). The contusion study presents work that can be used to enable medical examiners to better determine if the object in question was capable of causing the contusions present. Using a simple layered tissue model which represents a generic location on the human body, a sweep of objects with different edges properties is studied using a simple strain based injury metric. This analysis aims to examine the role that contact area and energy have on the formation, location, and shape of the resulting contusion. In studying the SLBT with finite element analysis and cohesive zone modeling, the assessment of various analytic models will provide insight into how to accurately measure the fracture energy for both the simulation and experiment. This provides insight into the interactions between a film, the substrate it is bonded to and the loading plug. In addition, parametric studies are used to examine potential experimental designs and enable future work in this field. The final product of this project provides tools and insight into future study of the effect rounded edges have on contact and this work enables for more focused studies within desired regimes of interest.

This article describes how service providers use a set of practical strategies to create an inclusive leisure space in Spiral Garden, an arts-mediated outdoor summer day program for children with and without disabilities. This study was guided by an interpretive qualitative approach. Fourteen Spiral Garden service providers participated in semi-structured interviews. Nine had extensive experience with the program and had been present during key phases of program development spanning over a 26-year period and five were service providers during the summer of 2013. Transcript data were analyzed using inductive thematic analysis. The analysis produced eight strategies organized under three larger categories that service providers perceived to be essential in creating an inclusive leisure space: (1) engaging children in collective experiences; (2) encouraging peer interactions and friendships; and (3) facilitating collaborative child-directed experiences. Service providers working across different inclusive settings can use findings from this study to contribute to program design and implementation. Presented strategies enable children to experience opportunities for spontaneous free play, individualized structured support, and meaningful social participation. Overall, service providers are encouraged to enhance supportive child and service provider relationships and reciprocal child and environment relationships in group-based programs. Implications for Rehabilitation Exploring and facilitating reciprocal relationships between children and their environment is essential to creating inclusive leisure spaces. Transforming program intentions of meaningful social participation into practice requires learning about and affecting change in children's individual social contexts. Service providers can engage themselves as full participants in inclusive leisure spaces through playful negotiations, internal reflections, and artistic expressions.

Most research on transitions of care has focused on the transition from acute to outpatient care. Little is known about the transition from outpatient to acute care. We conducted a systematic review of the literature on the transition from outpatient to acute care, focusing on provider-to-provider communication and its impact on quality of care. We searched the MEDLINE, CINAHL, Scopus, EMBASE, and Cochrane databases for English-language articles describing direct communication between outpatient providers and acute care providers around patients presenting to the emergency department or admitted to the hospital. We conducted double, independent review of titles, abstracts, and full text articles. Conflicts were resolved by consensus. Included articles were abstracted using standardized forms. We maintained search results via Refworks (ProQuest, Bethesda, MD). Risk of bias was assessed using a modified version of the Downs' and Black's tool. Of 4009 citations, twenty articles evaluated direct provider-to-provider communication around the outpatient to acute care transition. Most studies were cross-sectional (65%), conducted in the US (55%), and studied communication between primary care and inpatient providers (62%). Of three studies reporting on the association between communication and 30-day readmissions, none found a significant association; of these studies, only one reported a measure of association (adjusted OR for communication vs. no communication, 1.08; 95% CI 0.92-1.26). The literature on provider-to-provider communication at the transition from outpatient to acute care is sparse and heterogeneous. Given the known importance of communication for other transitions of care, future studies are needed on provider-to-provider communication during this transition. Studies evaluating ideal methods for communication to reduce medical errors, utilization, and optimize patient satisfaction at this transition are especially needed.
