This in vitro study aimed at comparing the effect of agitating the final irrigant solutions of root canal by ultrasonic or using 808 nm Diode laser on the apical seal of canal. A total of 90 extracted human maxillary central incisors were prepared up to size #45 and were randomly assigned to 4 experimental groups ( n =20) and two control groups ( n =5) respectively, as follows: I ): 3 mL of 5.25% NaOCl was agitated as final irrigant solution with ultrasonic for 30 sec. The ultrasonic tip was 1 mm shorter than the working length, II ): 3 mL of 5.25% NaOCl was agitated as final irrigant with 808 nm Diode laser for 30 sec. Fiber tip, placed in 1 mm shorter from working length was spirally moved coronally, III ): 3 mL of 17% EDTA was agitated as final irrigant with 808 nm Diode laser for 30 sec and was applied similar to group II, IV ): 3 mL of 17% EDTA was stimulated as final irrigant with ultrasonic for 30 sec and was applied similar to I. Apical seal was assessed by Dual Chamber technique using Bovine Serum Albumin protein. Kruskal-Wallis and Mann Whitney tests were used with significance level lower than 0.05% for statistical analysis. The average leakage in the negative control, positive control, and groups I, II, III, IV were: 0.00, 13.5±5.1, 1.72±2.9, 5.12±5.6, 3.36±3.7, 2.4±4.2, respectively. Statistical analysis showed significant difference between groups ( P <0.05). There was a significant difference between groups 1 and 2 in terms of protein leakage . Agitating 5.25% sodium hypochlorite solution as the final irrigant with ultrasonic is more effective in apical leakage reduction compared to other groups.

In Balint groups, (para)medical professionals explore difficult interactions with patients by means of case presentations and discussions. As the process of Balint group work is not well understood, this article investigates Balint group meetings by making use of Lacan's theory of the four discourses. Five Balint group case presentations and their subsequent group discussion were studied, resulting in the observation of five crucial aspects of Balint group work. First, Balint group participants brought puzzlement to the group, which is indicative of the structural impossibility Lacan situates at the basis of all discourse (1). As for the group discussion, we emphasize 'hysterization' as a crucial process in Balint group work (2), the supporting role of the discourse of the analyst (3) and the centrality of discourse interactions (4). Finally, the potential transformation of the initial puzzlement is discussed (5). We conclude by putting forth the uniqueness of Balint group work as well as the potential usefulness of our analysis as a framework for Balint group leaders and professionals in charge of continuing medical education. © The Author(s) 2016.

Occupational injury and illness recording and reporting requirements--NAICS update and reporting revisions. Final rule.

PubMed

2014-09-18

OSHA is issuing a final rule to update the appendix to its Injury and Illness Recording and Reporting regulation. The appendix contains a list of industries that are partially exempt from requirements to keep records of work-related injuries and illnesses due to relatively low occupational injury and illness rates. The updated appendix is based on more recent injury and illness data and lists industry groups classified by the North American Industry Classification System (NAICS). The current appendix lists industries classified by Standard Industrial Classification (SIC). The final rule also revises the requirements for reporting work-related fatality, injury, and illness information to OSHA. The current regulation requires employers to report work-related fatalities and in-patient hospitalizations of three or more employees within eight hours of the event. The final rule retains the requirement for employers to report work-related fatalities to OSHA within eight hours of the event but amends the regulation to require employers to report all work-related in-patient hospitalizations, as well as amputations and losses of an eye, to OSHA within 24 hours of the event.

Fries, Rainer; Ko, Che-Ming

This final report summarizes the work done by PIs at Texas A&M University within the JET Topical Collaboration. The main focus of the group at Texas A&M has been the development and implementation of a hadronization model suitable to calculate hadronization of jet showers in heavy ion collisions event by event. The group successfully developed a hybrid model of parton recombination and remnant string fragmentation including recombination with thermal partons. A code realizing this model was developed and shared with other JET members. In addition, the group at Texas A&M worked on both open and hidden heavy flavor probes. Inmore » particular, they developed a description of heavy flavor hadronization based on recombination, and consistent with in-medium scattering rates of heavy quarks, and suggested the D s meson as a precise probe of the hadronization mechanism. Another noteworthy focus of their work was electromagnetic probes, in particular, dileptons and photons from interactions of jets with the medium. In the soft sector the group has made several contributions to modern topics, e.g. the splitting of elliptic flow between isospin partners and the role of the initial strong gluon fields.« less

In honor of his 75th birthday, we review the prominent works of Professor Julien Clinton Sprott in chaos and nonlinear dynamics. We categorize his works into three important groups. The first and most important group is identifying new dynamical systems with special properties. He has proposed different chaotic maps, flows, complex variable systems, nonautonomous systems, partial differential equations, fractional-order systems, delay differential systems, spatiotemporal systems, artificial neural networks, and chaotic electrical circuits. He has also studied dynamical properties of complex systems such as bifurcations and basins of attraction. He has done work on generating fractal art. He has examined models of real-world systems that exhibit chaos. The second group of his works comprise control and synchronization of chaos. Finally, the third group is extracting dynamical properties of systems using time-series analysis. This paper highlights the impact of Sprott’s work on the promotion of nonlinear dynamics.

1984-08-15

A prospective, randomized, masked clinical trial to assess the value of limited physical activity after scleral buckling surgery included 108 consecutive patients with rhegmatogenous retinal detachment randomly divided into two groups. The first group was encouraged to resume full physical activity immediately after hospital discharge. In the second group, bending, lifting, straining at stool, driving, sexual activity, lawnmowing, gardening, athletics, and returning to work were strictly forbidden for six weeks. A thorough evaluation of patient compliance was performed after six weeks. Six months after surgery the rates of reoperation and final reattachment percentages of the active and inactive groups showed no statistically significant difference (P greater than .05). Final visual acuity, measured one year after surgery, also identified no statistically significant difference between the groups (P greater than .05).

Group Work Tests for Context-Rich Problems

NASA Astrophysics Data System (ADS)

Meyer, Chris

2016-05-01

The group work test is an assessment strategy that promotes higher-order thinking skills for solving context-rich problems. With this format, teachers are able to pose challenging, nuanced questions on a test, while providing the support weaker students need to get started and show their understanding. The test begins with a group discussion phase, when students are given a "number-free" version of the problem. This phase allows students to digest the story-like problem, explore solution ideas, and alleviate some test anxiety. After 10-15 minutes of discussion, students inform the instructor of their readiness for the individual part of the test. What follows next is a pedagogical phase change from lively group discussion to quiet individual work. The group work test is a natural continuation of the group work in our daily physics classes and helps reinforce the importance of collaboration. This method has met with success at York Mills Collegiate Institute, in Toronto, Ontario, where it has been used consistently for unit tests and the final exam of the grade 12 university preparation physics course.

Expediting rotator cuff surgery is expected to facilitate recovery and return to work in injured workers. This case-control study examined the effect of expedited rotator cuff surgery on recovery and work status in injured workers. Injured workers who had undergone an expedited rotator cuff surgery funded by parallel-pay insurance (study group) were compared with workers who had used the public health insurance (control group) while adjusting for sex, age, severity of pathology, and follow-up period. Disability was measured by the American Shoulder and Elbow Surgeons (ASES) Standardized Assessment Form score. The percentage of patients who exceeded the minimal clinically important difference of 17 points in the ASES was calculated. The study group waited less time to have surgery than the control group (P < .0001), reported less disability after surgery, and had a higher number of patients whose improvement exceeded the minimal clinically important difference (119 vs. 65, P < .0001). The study group was more likely to be working at the time of the final follow-up (P < .0001). The final multivariable regressions, which adjusted for unmatched variables, such as dominant side involvement, mechanism of injury, and associated operations that were different between groups, were consistent with univariable analyses indicating superior results in the study group. Injured workers who underwent expedited rotator cuff surgery reported less disability and had a more successful return to work after surgery than injured workers who waited longer for specialist assessment and surgery within the public health system.

Women in medicine continue to experience disparities in earnings, promotion, and leadership roles. There are few guidelines in place defining organization-level factors that promote a supportive workplace environment beneficial to women in emergency medicine (EM). We assembled a working group with the goal of developing specific and feasible recommendations to support women's professional development in both community and academic EM settings. We formed a working group from the leadership of two EM women's organizations, the Academy of Women in Academic Emergency Medicine (AWAEM) and the American Association of Women Emergency Physicians (AAWEP). Through a literature search and discussion, working group members identified four domains where organizational policies and practices supportive of women were needed: 1) global approaches to supporting the recruitment, retention, and advancement of women in EM; 2) recruitment, hiring, and compensation of women emergency physicians; 3) supporting development and advancement of women in EM; and 4) physician health and wellness (in the context of pregnancy, childbirth, and maternity leave). Within each of these domains, the working group created an initial set of specific recommendations. The working group then recruited a stakeholder group of EM physician leaders across the country, selecting for diversity in practice setting, geographic location, age, race, and gender. Stakeholders were asked to score and provide feedback on each of the recommendations. Specific recommendations were retained by the working group if they achieved high rates of approval from the stakeholder group for importance and perceived feasibility. Those with >80% agreement on importance and >50% agreement on feasibility were retained. Finally, recommendations were posted in an open online forum (blog) and invited public commentary. An initial set of 29 potential recommendations was created by the working group. After stakeholder voting and feedback, 16 final recommendations were retained. Recommendations were refined through qualitative comments from stakeholders and blog respondents. Using a consensus building process that included male and female stakeholders from both academic and community EM settings, we developed recommendations for organizations to implement to create a workplace environment supportive of women in EM that were perceived as acceptable and feasible. This process may serve as a model for other medical specialties to establish clear, discrete organization-level practices aimed at supporting women physicians. © 2016 by the Society for Academic Emergency Medicine.

Interference control in working memory: comparing groups of children with atypical development.

PubMed

Palladino, Paola; Ferrari, Marcella

2013-01-01

The study aimed to test whether working memory deficits in children at risk of Learning Disabilities (LD) and/or attention deficit/hyperactivity disorder (ADHD) can be attributed to deficits in interference control, thereby implicating prefrontal systems. Two groups of children known for showing poor working memory (i.e., children with poor comprehension and children with ADHD) were compared to a group of children with specific reading decoding problems (i.e., having severe problems in phonological rather than working memory) and to a control group. All children were tested with a verbal working memory task. Interference control of irrelevant items was examined by a lexical decision task presented immediately after the final recall in about half the trials, selected at random. The interference control measure was therefore directly related to working memory performance. Results confirmed deficient working memory performance in poor comprehenders and children at risk of ADHD + LD. More interestingly, this working memory deficit was associated with greater activation of irrelevant information than in the control group. Poor decoders showed more efficient interference control, in contrast to poor comprehenders and ADHD + LD children. These results indicated that interfering items were still highly accessible to working memory in children who fail the working memory task. In turn, these findings strengthen and clarify the role of interference control, one of the most critical prefrontal functions, in working memory.

Using student motivation to design groups in a non-majors biology course for team-based collaborative learning: Impacts on knowledge, views, attitudes, and perceptions

NASA Astrophysics Data System (ADS)

Walters, Kristi L.

The importance of student motivation and its connection to other learning variables (i.e., attitudes, knowledge, persistence, attendance) is well established. Collaborative work at the undergraduate level has been recognized as a valuable tool in large courses. However, motivation and collaborative group work have rarely been combined. This project utilized student motivation to learn biology to place non-major biology undergraduates in collaborative learning groups at East Carolina University, a mid-sized southeastern American university, to determine the effects of this construct on student learning. A pre-test measuring motivation to learn biology, attitudes toward biology, perceptions of biology and biologists, views of science, and content knowledge was administered. A similar post-test followed as part of the final exam. Two sections of the same introductory biology course (n = 312) were used and students were divided into homogeneous and heterogeneous groups (based on their motivation score). The heterogeneous groups (n = 32) consisted of a mixture of different motivation levels, while the homogeneous groups (n = 32) were organized into teams with similar motivation scores using tiers of high-, middle-, and low-level participants. Data analysis determined mixed perceptions of biology and biologists. These include the perceptions biology was less intriguing, less relevant, less practical, less ethical, and less understandable. Biologists were perceived as being neat and slightly intelligent, but not very altruistic, humane, ethical, logical, honest, or moral. Content knowledge scores more than doubled from pre- to post-test. Half of the items measuring views of science were not statistically significantly different from pre- to post-test. Many of the factors for attitudes toward biology became more agreeable from pre- to post-test. Correlations between motivation scores, participation levels, attendance rates, and final course grades were examined at both the individual and group level. Motivation had low correlations with the other variables. Changes in group membership (i.e., attrition) were evaluated at the group level and showed the highest rates with the heterogeneous groups and the lowest with the homogeneous middle groups. Group gender ratios were examined, but showed no correlation with final course grade. Linear regression was utilized to identify any variables that might be useful in predicting the final course grade of each student. Only participation, attendance, and final exam grade were predictive, but as they were components of the final course grade, they were not useful for the model. Differences between the groups were also examined to determine if the group type was predictive of final course grade, but no significant difference was found. Results of the study are discussed in the context of the literature on student motivation to learn science. Implications of the study are discussed through the lens of the Millennial generation's perspectives on teaching and learning. Millennials often consider an education to be a commodity and may expect results with less effort. Millennials may be expressing a pseudo-intrinsic motivation in order to impress peers and instructors, while they may actually be more extrinsically motivated to succeed

(2) To identify work environment factors potentially contributing to burnout. Two groups were examined. The psychiatric group comprised 525 PHNs primarily engaged in public mental health services at public health centres (PHCs) that had adopted the job specific work system. The control group comprised 525 PHNs primarily engaged in other health services. Pines' Burnout Scale was used to measure burnout. Respondents were classified by burnout score into three groups: A (mentally stable, no burnout); B (positive signs, risk of burnout); and C (burnout present, action required). Groups B and C were considered representative of "burnout". A questionnaire was also prepared to investigate systems for supporting PHNs working at PHCs and to define emergency mental health service factors contributing to burnout. Final respondents comprised 785 PHNs. Prevalence of burnout was significantly higher in the psychiatric group (59.2%) than in the control group (51.5%). Responses indicating lack of job control and increased annual frequency of emergency overtime services were significantly correlated with prevalence of burnout in the psychiatric group, but not in the control group. Prevalence of burnout is significantly higher for community psychiatric nurses than for PHNs engaged in other services. Overwork in emergency services and lack of job control appear to represent work environment factors contributing to burnout.

The Job Demands-Resources model (JD-R model) was used as the theoretical basis of a tailormade questionnaire to measure the psychosocial work environment and personal resources of recently graduated veterinary professionals. According to the JD-R model, two broad categories of work characteristics that determine employee wellbeing can be distinguished: job demands and job resources. Recently, the JD-R model has been expanded by integrating personal resource measures into the model. Three semistructured group interviews with veterinarians active in different work domains were conducted to identify relevant job demands, job resources and personal resources. These demands and resources were organised in themes (constructs). For measurement purposes, a set of questions ('a priori scale') was selected from the literature for each theme. The full set of a priori scales was included in a questionnaire that was administered to 1760 veterinary professionals. Exploratory factor analysis and reliability analysis were conducted to arrive at the final set of validated scales (final scales). 860 veterinarians (73 per cent females) participated. The final set of scales consisted of seven job demands scales (32 items), nine job resources scales (41 items), and six personal resources scales (26 items) which were considered to represent the most relevant potential predictors of work-related wellbeing in this occupational group. The procedure resulted in a tailormade questionnaire: the Veterinary Job Demands and Resources Questionnaire (Vet-DRQ). The use of valid theory and validated scales enhances opportunities for comparative national and international research.

A hypersonic transport aircraft design project was selected as a result of interactions with NASA Lewis Research Center personnel and fits the Presidential concept of the Orient Express. The Graduate Teaching Assistant (GTA) and an undergraduate student worked at the NASA Lewis Research Center during the 1986 summer conducting a literature survey, and relevant literature and useful software were collected. The computer software was implemented in the Computer Aided Design Laboratory of the Mechanical and Aerospace Engineering Department. In addition to the lectures by the three instructors, a series of guest lectures was conducted. The first of these lectures 'Anywhere in the World in Two Hours' was delivered by R. Luidens of NASA Lewis Center. In addition, videotaped copies of relevant seminars obtained from NASA Lewis were also featured. The first assignment was to individually research and develop the mission requirements and to discuss the findings with the class. The class in consultation with the instructors then developed a set of unified mission requirements. Then the class was divided into three design groups (1) Aerodynamics Group, (2) Propulsion Group, and (3) Structures and Thermal Analyses Group. The groups worked on their respective design areas and interacted with each other to finally come up with an integrated conceptual design. The three faculty members and the GTA acted as the resource persons for the three groups and aided in the integration of the individual group designs into the final design of a hypersonic aircraft.

OSIRIS-REx and mission sample science: The return of at least 60 g of pristine regolith from asteroid Bennu

NASA Astrophysics Data System (ADS)

Connolly, H. C., Jr.; Lauretta, D. S.

2014-07-01

Introduction: The Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) asteroid sample return mission was selected by NASA in May 2011 as the third New Frontiers mission. The target, (101955) Bennu, is a B-type near-Earth asteroid (NEA), hypothesized to be similar to CI or CM carbonaceous chondrites. The key science objectives of the mission are summarized in [1]. To meet these science objectives, the science team is coordinated and governed by the Science Executive Council (SEC): A group of six persons that run various elements of mission science. Mission Sample Science (MSS) is charged with analysis of the returned sample. Mission Sample Science: MSS is run by a Mission Scientist and composed of the following working groups: Carbonaceous Meteorite Working Group (CMWG), Dynamical Evolution Working Group (DEWG), Regolith Development Working Group (RDWG), Sample Analysis Working Group (SampleWG), Sample Site Science Working Group (SSSWG), and TAGSAM Working Group (TAGSAMWG). CMWG works to define and create well-characterized test samples, both natural and synthetic, for the development of spectral test data. These data are used to verify the depth and accuracy of spectral analysis techniques for processing data collected by the OSIRIS-REx spectrometers (OVIRS and OTES). The DEWG is charged with constraining the history of asteroid Bennu from main-belt asteroid to NEA. They also work closely with the SampleWG to define the hypotheses for the dynamical evolution of Bennu through the analysis of the returned sample. The RDWG is focused on developing constraints on the origin and evolution of regolith on Bennu through investigations of the surface geology and, working with the SampleWG, test these hypotheses through sample analysis. RDWG is also focused on the analysis of the sampling event and reconstructing what occurred during the event. SampleWG is focused on documenting Contamination Knowledge, which is distinct but related to mission Contamination Control. The main deliverable for this working group is the Sample Analysis Plan, due in 2019. Furthermore, it is this working group that is responsible for constituting the Preliminary Examination Team (PET) and performing the analyses of the returned sample during the first six months after return. SSSWG has the main deliverable of providing to the project the Science Value Maps (SVMs), which are part of the sample site selection process. If we can deliver the spacecraft to candidate sample sites, if it is safe to sample at them, and if there is material that can be ingested, SVMs will be a semi-quantitative aid in picking the optimum site to meet mission science goals. Finally, TAGSAM (Touch And Go Sample Acquisition Mechanism) is the sampler for the mission and this working group is concerned primarily with characterizing TAGSAM capabilities against a range of regolith types. Mission Sample Science provides an over-arching structure to reconstruct the pre- and post-accretion history of Bennu from the formation of pre-solar grains, chondrules, up to geological activity within the asteroid to its final dynamical evolution through analysis of the returned sample using a wide range of disciplines and expertise.

Purpose Employer policies and practices have been shown to impact workplace disability, but research in this area has waned in recent years despite an aging workforce, a growing prevalence of chronic health conditions, and a larger proportion of working-age adults on permanent work disability in many jurisdictions. The purpose of this article is to describe the background rationale and methodology for an invited conference designed to improve research of employer strategies to curtail work disability. Methods A multidisciplinary team of 26 international researchers with published research in employer-based disability management or related fields were invited to attend a 3-day conference in Hopkinton, Massachusetts, USA. The overall goal was to review the status of current research of workplace disability management and prevention, examine its relevance for employer decision-making, compare conceptual frameworks or theoretical perspectives, and recommend future research directions. Working groups were organized and draft manuscripts were prepared in advance. Conference activities included working group presentations and critiques, discussions with a panel of industry consultants and advisors, group interaction and debate, generation of final recommendations, and manuscript revision. Results/Conclusion Six principal domains were established with respect to future research: (a) further elucidation of the key workplace factors that buffer the disabling effects of injury and illness; (b) more innovative and feasible options for workplace intervention; (c) measurement of workplace-relevant disability outcomes; (d) a stronger theoretical framework for understanding the factors behind employer uptake and implementation; (e) a focus on special clinical populations and occupations where disability risk is most troubling; and (f) better representation of workers and employers that reflect the diverse and changing nature of work. Final comments and recommendations of the working groups are presented in the following six articles in this special issue of the Journal of Occupational Rehabilitation. Conference attendees recommended changes in methodology, collaboration strategies, and theoretical perspectives to improve the practical and scientific impact of future research of employer practices.

Active learning in college classes and participation in the workforce frequently hinge on small group work. However, group dynamics vary, ranging from equitable collaboration to dysfunctional groups dominated by one individual. To explore how group dynamics impact student learning, we asked students in a large-enrollment university biology class to self-report their experience during in-class group work. Specifically, we asked students whether there was a friend in their group, whether they were comfortable in their group, and whether someone dominated their group. Surveys were administered after students participated in two different types of intentionally constructed group activities: 1) a loosely-structured activity wherein students worked together for an entire class period (termed the ‘single-group’ activity), or 2) a highly-structured ‘jigsaw’ activity wherein students first independently mastered different subtopics, then formed new groups to peer-teach their respective subtopics. We measured content mastery by the change in score on identical pre-/post-tests. We then investigated whether activity type or student demographics predicted the likelihood of reporting working with a dominator, being comfortable in their group, or working with a friend. We found that students who more strongly agreed that they worked with a dominator were 17.8% less likely to answer an additional question correct on the 8-question post-test. Similarly, when students were comfortable in their group, content mastery increased by 27.5%. Working with a friend was the single biggest predictor of student comfort, although working with a friend did not impact performance. Finally, we found that students were 67% less likely to agree that someone dominated their group during the jigsaw activities than during the single group activities. We conclude that group activities that rely on positive interdependence, and include turn-taking and have explicit prompts for students to explain their reasoning, such as our jigsaw, can help reduce the negative impact of inequitable groups.

The evidence underpinning the developmental origins of health and disease (DOHaD) is overwhelming. As the emphasis shifts more towards interventions and the translational strategies for disease prevention, it is important to capitalize on collaboration and knowledge sharing to maximize opportunities for discovery and replication. DOHaD meetings are facilitating this interaction. However, strategies to perpetuate focussed discussions and collaborations around and between conferences are more likely to facilitate the development of DOHaD research. For this reason, the DOHaD Society of Australia and New Zealand (DOHaD ANZ) has initiated themed Working Groups, which convened at the 2014-2015 conferences. This report introduces the DOHaD ANZ Working Groups and summarizes their plans and activities. One of the first Working Groups to form was the ActEarly birth cohort group, which is moving towards more translational goals. Reflecting growing emphasis on the impact of early life biodiversity - even before birth - we also have a Working Group titled Infection, inflammation and the microbiome. We have several Working Groups exploring other major non-cancerous disease outcomes over the lifespan, including Brain, behaviour and development and Obesity, cardiovascular and metabolic health. The Epigenetics and Animal Models Working Groups cut across all these areas and seeks to ensure interaction between researchers. Finally, we have a group focussed on 'Translation, policy and communication' which focusses on how we can best take the evidence we produce into the community to effect change. By coordinating and perpetuating DOHaD discussions in this way we aim to enhance DOHaD research in our region.

In the present work we study the different dimensions of satisfaction and the way of constitution of satisfaction of an important sample of the employees in the Regional administration of Crete and in their connection with the variable of the previous employment. We found statistically important differences for the components of satisfaction from the life, collaboration in and outside from the department, in the social satisfaction and the variable of the years in the service (labour group with <5 years in the service, group with 5-9 years in the service and labour group with 10-15 years in the service). The group with total few years in the work <5, presented smaller social and labour satisfaction than the other previous employment groups. In the other hand the group with many years in the service presents bigger satisfaction than the other groups. Finally, is important to note that the sample present some interesting characteristics.

Progress report of the IAU Commission 4 Working Group on Ephemeris Access and the comparison of high accuracy planetary ephemerides

NASA Astrophysics Data System (ADS)

Hilton, J. L.

2012-12-01

In September 2010 IAU Commission 4, Ephemerides, organized a working group to provide a recommendation for a preferred format for solar system ephemerides. The purpose of this recommendation is to provide easy access to a wide range of solar system ephemerides for users. The working group, chaired by Hilton, includes representatives from each of the major planetary ephemeris groups and representatives from the satellite and asteroid ephemeris communities. The working group has tentatively decided to recommend the SPK format developed by the Jet Propulsion Laboratory's Navigation and Ancillary Information Facility for use with its SPICE Toolkit. Certain details, however, must still be resolved before a final recommendation is made by the working group. An update is also provided to ongoing analysis comparing the three high accuracy planetary ephemerides, DE421, EPM2008, and INPOP10a. The principal topics of this update are: replacing the INPOP08 ephemeris with the INPOP10a ephemeris, making the comparisons with respect to DE421 rather than DE405, and comparing the TT - TDB values determined in EPM2008 and INPOP10a with the Fairhead & Bretagnon (1990, A&A, 229, 240) model used in DE421 as T_eph.

Since long ago the nurse has become more concerned about the delivery of care for patients with chronic and degeneratives diseases. Nevertheless, the accomplishment of this task is not an easy one. Moreover, when the patient reaches the final stage. Usually this patient experiences emotional and physical alteration. The family is deeply involved in this process and generally they seek nurses help because they are the closest ones to the patient and his/her family. When the patient go trough this dramatic acute change in health condition or in face of chronic degenerative or final stage disease is made, the relationship with the family becomes more difficult demanding nursing intervention. The objective of this study is to report the experience of nurse's participation in the implantation and development of multidisciplinary group for treatment of chronical and final stage patients. This group has been working for two years and has had good results. This group has worked treatment schemes for treatment used by all members of multidisciplinary team. From previous experiences, we knew that there is always a discrepancy between the information given by professional and friends and relatives ones. Which could increase fear and anxiety the reassurance given by the health team, a fair distribution of tasks and the information delivery to the patient proved to be successful.

To determine the preparedness levels of final-year Turkish nursing students starting their careers as professional nurses. The transition from nursing student to professional nurse is challenging. One of the ways to help facilitate this transition is to determine how well students are prepared to start work. There are limited, but conflicting, results on this topic. Mixed-methods study. Undergraduate nursing students (n = 4490) in their final year of study from 74 Turkish universities were eligible to participate in this study. Of these, 1804 total students participated from 38 randomly selected universities. Data were collected through an investigator-developed questionnaire (n = 1804) and focus group interviews (n = 57). Students felt highly prepared to start work (57·6%). Those who were older, male, graduates of a vocational high school or already working as a nurse felt most prepared. Students who felt that their education preparation and resources were adequate felt more prepared. Focus group interviews revealed that students felt confident in their knowledge of educational theory, but not in clinical skills. Students may have felt prepared to start work, but insufficient clinical experience probably contributed to a lack of confidence in their skills. The resources of the school, the quality of the education, and the clinical practice environments were considered most important for the students' perceived preparedness levels. An undergraduate education provides the foundation for successful nurse preparation. A good clinical environment along with a high-quality education programme can help give students more confidence in their skills when they join the nursing workforce. Internship or residency programmes may also facilitate this learning. This is extremely important for safe, high-quality patient care. © 2014 John Wiley & Sons Ltd.

Absence of back disorders in adults and work-related predictive factors in a 5-year perspective.

Reigo, T; Tropp, H; Timpka, T

2001-06-01

Factors important for avoiding back disorders in different age-groups have seldom been compared and studied over time. We therefore set out to study age-related differences in socio-economic and work-related factors associated with the absence of back disorders in a 5-year comparative cohort study using a mailed questionnaire. Two subgroups (aged 25-34 and 54-59 years) derived from a representative sample of the Swedish population were followed at baseline, 1 year and 5 years. Questions were asked about the duration of back pain episodes, relapses, work changes and work satisfaction. A work adaptability, partnership, growth, affection, resolve (APGAR) score was included in the final questionnaire. Multivariate logistic regression was used to identify factors predicting the absence of back disorders. Absence of physically heavy work predicted an absence of back disorders [odds ratio (OR), 2.86; 95% confidence interval (CI), 1.3-6.3] in the older group. In the younger age-group, the absence of stressful work predicted absence of back disorders (OR, 2.0; 95% CI, 1.1-3.6). Thirty-seven per cent of the younger age-group and 43% of the older age-group did not experience any back pain episodes during the study period. The exploratory work APGAR scores indicated that back disorders were only associated with lower work satisfaction in the older group. The analyses point out the importance of avoiding perceived psychological stress in the young and avoiding perceived physically heavy work in the older age-group for avoiding back disorders. The results suggest a need for different programmes at workplaces to avoid back disorders depending on the age of the employees concerned.

With the goal of generate uniform criteria among centers dealing with pituitary tumors and to enhance patient care, the Pituitary Society decided to generate criteria for developing Pituitary Tumors Centers of Excellence (PTCOE). To develop that task, a group of ten experts served as a Task Force and through two years of iterative work an initial draft was elaborated. This draft was discussed, modified and finally approved by the Board of Directors of the Pituitary Society. Such document was presented and debated at a specific session of the Congress of the Pituitary Society, Orlando 2017, and suggestions were incorporated. Finally the document was distributed to a large group of global experts that introduced further modifications with final endorsement. After five years of iterative work a document with the ideal criteria for a PTCOE is presented. Acknowledging that very few centers in the world, if any, likely fulfill the requirements here presented, the document may be a tool to guide improvements of care delivery to patients with pituitary disorders. All these criteria must be accommodated to the regulations and organization of Health of a given country.

Background Dental graduates are joining a profession experiencing changes in systems of care, funding and skill mix. Research into the motivation and expectations of the emerging workforce is vital to inform professional and policy decisions. The objective of this research was to investigate final year dental students' perceived motivation for their choice of career in relation to sex, ethnicity and mode of entry. Methods Self-administered questionnaire survey of all final year dental students at King's College London. Data were entered into SPSS; statistical analysis included Chi Squared tests for linear association, multiple regression, factor analysis and logistic regression. Results A response of 90% (n = 126) was achieved. The majority were aged 23 years (59%), female (58%) and Asian (70%). One in 10 were mature students. Eighty per cent identified 11 or more 'important' or 'very important' influences, the most common of which were related to features of the job: 'regular working hours' (91%), 'degree leading to recognised job' (90%) and 'job security' (90%). There were significant differences in important influences by sex (males > females: 'able to run own business'; females > males: 'a desire to work with people'), ethnic group (Asians > white: 'wish to provide public service', 'influence of friends', 'desire to work in healthcare', having 'tried an alternative career/course' and 'work experience') and mode of entry (mature > early entry: 'a desire to work with people'). Multivariate analysis suggested 61% of the variation in influences is explained by five factors: the 'professional job' (31%), 'healthcare-people' (11%), 'academic-scientific' (8%), 'careers-advising' (6%), and 'family/friends' (6%). The single major influence on choice of career was a 'desire to work with people'; Indian students were twice as likely to report this as white or other ethnic groups. Conclusion Final year dental students report a wide range of important influences on their choice of dentistry, with variation by sex, ethnicity and mode of entry in relation to individual influences. Features of the 'professional job', followed by 'healthcare and people' were the most important underlying factors influencing choice of career. PMID:17573967

The International Dermatology Outcome Measures (IDEOM) psoriasis working group was established to develop core domains and measurements sets for psoriasis clinical trials and ultimately clinical practice. At the 2016 annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis, the IDEOM psoriasis group presented an overview of its progress toward developing this psoriasis core domain set. First, it summarized the February 2016 meeting of all involved with the IDEOM, highlighting patient and payer perspectives on outcome measures. Second, the group presented an overview of the consensus process for developing the core domain set for psoriasis, including previous literature reviews, nominal group exercises, and meeting discussions. Future plans include the development of working groups to review candidate measures for at least 2 of the domains, including primary pathophysiologic manifestations and patient-reported outcomes, and Delphi surveys to gain consensus on the final psoriasis core domain set.

Krohn, Wolfgang

2014-01-01

In the Starnberg Max-Planck Institute one of the working groups was concerned with science as the formative condition--or "hard core"--of societal modernity, and with science as potential resource for solving social problems and addressing future goals. More precisely, the group intended to differentiate between phases in which scientific disciplines predominantly care for their own paradigmatic completion and those allowing their theoretical potential resonate with external needs. The conceptual model was coined "finalization in science". It soon provoked a heated controversy on the dangers of social control of science. The paper analyses Carl Friedrich von Weizsäcker's views on the relation between philosophy and policy of science including his interpretation of Thomas Kuhn and reconstructs the impact of his ideas on the finalization model. It finally reflects on the relationship between science development and change of consciousness in the context of scientific responsibility for (the use of) research outcomes.

Global health systems are shifting toward value-based care in an effort to drive better outcomes in the setting of rising health care costs. This shift requires a common definition of value, starting with the outcomes that matter most to patients. The International Consortium for Health Outcomes Measurement (ICHOM), a nonprofit initiative, was formed to define standard sets of outcomes by medical condition. In this article, we report the efforts of ICHOM's working group in colorectal cancer. The working group was composed of multidisciplinary oncology specialists in medicine, surgery, radiation therapy, palliative care, nursing, and pathology, along with patient representatives. Through a modified Delphi process during 8 months (July 8, 2015 to February 29, 2016), ICHOM led the working group to a consensus on a final recommended standard set. The process was supported by a systematic PubMed literature review (1042 randomized clinical trials and guidelines from June 3, 2005, to June 3, 2015), a patient focus group (11 patients with early and metastatic colorectal cancer convened during a teleconference in August 2015), and a patient validation survey (among 276 patients with and survivors of colorectal cancer between October 15, 2015, and November 4, 2015). After consolidating findings of the literature review and focus group meeting, a list of 40 outcomes was presented to the WG and underwent voting. The final recommendation includes outcomes in the following categories: survival and disease control, disutility of care, degree of health, and quality of death. Selected case-mix factors were recommended to be collected at baseline to facilitate comparison of results across treatments and health care professionals. A standardized set of patient-centered outcome measures to inform value-based health care in colorectal cancer was developed. Pilot efforts are under way to measure the standard set among members of the working group.

To compare outcomes of 3 patient groups undergoing hip arthroscopy. This study included 138 consecutive hip arthroscopies (106 analyzed) for femoral-acetabular impingement (FAI) with or without labral tear in patients with a minimum 1-year follow-up. Inclusion criteria included patients older than 18 with clinical or radiologic manifestation of FAI with or without labral tear. Exclusion criteria included previous hip surgery and various hip pathologies. Patients were classified into 3 study groups. Group 1 included work-related injuries with active claims ACs (n = 33); mean age, 32 (range, 19 to 63); group 2 included sports injuries with no ACs (n = 35); mean age, 32 (range, 18 to 69); and group 3 included non-sports-related injuries without pending ACs (NAS; n = 38); mean age, 45 (range, 20 to 68). Outcomes were assessed using modified Harris hip scores (mHHS) and hip outcome scores (HOS) preoperatively and during the final evaluation. Baseline score for all groups did not significantly differ (P = .210 for mHHS, P = .176 for HOS). All groups significantly improved from preoperative to final evaluation (group 1: mHHS P = .42, HOS P = .001; group 2: mHHS P < .001, HOS P < .001; group 3 NAS: mHHS P = .001, HOS P = .007). AC patients had the lowest final evaluation scores, while the sports group had the highest. The NAS group did not differ from either group at final evaluation. Preoperative and final evaluation scores inversely correlated with age (r range, -24 to -28; P < .05). This study has shown that patients may benefit from arthroscopic repair of FAI and labral tears regardless of ACs. The level of improvement, however, is not constant across patients with different characteristics. Moreover, it appears that age may impact perceived improvement after hip arthroscopy. Hip arthroscopy as an intervention in patients with ACs provided positive outcomes, corroborating that an AC is not a contraindication for this procedure. Level III, retrospective comparative study.

[A Group Cognitive-Behavioural Intervention to Prevent Depression Relapse in Individuals Having Recently Returned to Work: Protocol and Feasibility].

PubMed

Lecomte, Tania; Corbière, Marc

Workplace depression is one of the major causes for sick leave and loss of productivity at work. Many studies have investigated factors predicting return to work for people with depression, including studies evaluating return to work programs and organizational factors. Yet, a paucity of studies have targeted the prevention of depressive relapses at work, even though more than half of those having had a depression will have a depressive relapse in the near future.Objectives This article describes a research protocol involving a novel group intervention based on cognitive behavioural principles with the aim to optimize return to work and diminish risk of depressive relapses.Method This pilot study follows a randomized controlled trial design, with half the participants (N=25) receiving the group intervention and the other half (N=25) receiving usual services. The theoretical and empirical underpinnings of the intervention are described, along with a detailed presentation of the intervention and of the study's objectives. The group intervention consists of 8 sessions whereby Cognitive behavioural therapy (CBT) principles and techniques are applied to the following themes: (1) Coping with stress at work; (2) Recognizing and modifying my dysfunctional beliefs linked to work; (3) Overcoming obstacles linked to work functioning and maintaining work; (4) Negotiating needed work adjustments with the support of the immediate supervisor; (5) Finding my strengths and competencies related to work; (6) Accepting criticism and asserting myself appropriately at work; (7) Uncovering my best coping strategies for work.Results Qualitative information pertaining to the first two cohorts' participants' subjective appreciation of the group experience revealed that the intervention was perceived as very useful by all, with group support, namely harmony and interpersonal support, as well as CBT strategies being mentioned specifically.Conclusion Finally, the potential relevance of the group intervention will be brought forward.

Objective The Work Role Functioning Questionnaire v2.0 (WRFQ) is an outcome measure linking a persons' health to the ability to meet work demands in the twenty-first century. We aimed to examine the construct validity of the WRFQ in a heterogeneous set of working samples in the Netherlands with mixed clinical conditions and job types to evaluate the comparability of the scale structure. Methods Confirmatory factor and multi-group analyses were conducted in six cross-sectional working samples (total N = 2433) to evaluate and compare a five-factor model structure of the WRFQ (work scheduling demands, output demands, physical demands, mental and social demands, and flexibility demands). Model fit indices were calculated based on RMSEA ≤ 0.08 and CFI ≥ 0.95. After fitting the five-factor model, the multidimensional structure of the instrument was evaluated across samples using a second order factor model. Results The factor structure was robust across samples and a multi-group model had adequate fit (RMSEA = 0.63, CFI = 0.972). In sample specific analyses, minor modifications were necessary in three samples (final RMSEA 0.055-0.080, final CFI between 0.955 and 0.989). Applying the previous first order specifications, a second order factor model had adequate fit in all samples. Conclusion A five-factor model of the WRFQ showed consistent structural validity across samples. A second order factor model showed adequate fit, but the second order factor loadings varied across samples. Therefore subscale scores are recommended to compare across different clinical and working samples.

For lung cancer surgery, a narrative operative report is the standard reporting procedure, whereas a synoptic-style report is increasingly utilized by healthcare professionals in various specialties with great success. A synoptic operative report more succinctly and accurately captures vital information and is rapidly generated with good intraobserver reliability. The objective of this study was to systematically develop a synoptic operative report for lung cancer surgery following a modified Delphi consensus model with the support of the Canadian thoracic surgery community. Using online survey software, thoracic surgeons and related physicians were asked to suggest and rate data elements for a synoptic report following the modified Delphi consensus model. The consensus exercise-derived template was forwarded to a small working group, who further refined the definition and priority designation of elements until the working group had reached a satisfactory consensus. In all, 139 physicians were invited to participate in the consensus exercise, with 36.7%, 44.6%, and 19.5% response rates, respectively, in the three rounds. Eighty-nine elements were agreed upon at the conclusion of the exercise, but 141 elements were forwarded to the working group. The working group agreed upon a final data set of 180 independently defined data elements, with 72 mandatory and 108 optional elements for implementation in the final report. This study demonstrates the process involved in developing a multidisciplinary, consensus-based synoptic lung cancer operative report. This novel report style is a quality improvement initiative to improve the capture, dissemination, readability, and potential utility of critical surgical information.

Intertrial correlations and intertrial periods of rest.

PubMed

Jones, M B

1969-03-01

Eight groups of 40 basic airmen each worked the Manual Crank for an initial period of 5 min., rested, and then worked for a final period of 3 min. The eight groups were distinguished according to the load (heavy or light) against which they worked in the two periods and the rest interval (30 sec. or 4 min.) between them. Response was scored in revolutions of the crank handle in each 20 sec. interval (trial). None of the main effects had any bearing on the intertrial correlations within or between the periods of cranking. The results lend further support to the proposition that intertrial correlations are invariant under rest interval (distribution of practice) and the force required to make a response.

Hypothetical biotechnology companies: A role-playing student centered activity for undergraduate science students.

PubMed

Chuck, Jo-Anne

2011-01-01

Science students leaving undergraduate programs are entering the biotechnology industry where they are presented with issues which require integration of science content. Students find this difficult as through-out their studies, most content is limited to a single subdiscipline (e.g., biochemistry, immunology). In addition, students need knowledge of the ethical, economic, and legal frame work in which the industry operates. This article presents an approach to deliver these outcomes in a collaborative and active learning modality which promotes deep learning. In the model, groups of final year undergraduate students form hypothetical biotechnology companies and identify real issues of interest to industry, make integrative team decisions, use professional level technology, and develop appropriate communication skills. The final successful teaching paradigm was based on self reflection, observation, and student feedback to ensure appropriate attainment of content, group work skills and increased confidence in professional decision-making. It is these outcomes which will facilitate life long learning skills, a major outcome applicable for all tertiary education. Copyright © 2011 Wiley Periodicals, Inc.

This research aimed to investigate the effect that rational-emotive behavior therapy had on the symptoms of burnout among undergraduate electronics work students in Southeast Nigeria. This study utilized a pretest-posttest design involving a no-intervention group versus an intervention group. Participants were 124 undergraduate electronics work students who met the inclusion criteria of the study. The intervention consisted of 12 weeks of rational-emotive behavior therapy treatment and 2 weeks of follow-up meetings conducted at 6 months. Self-report questionnaire was used for data collection. Repeated measures analysis of variance and t test were used for data analysis. The results show that rational-emotive behavior therapy had a significant effect on the symptoms of burnout syndrome among the electronics work students in the treatment group compared to their counterparts in the no-intervention group. Finally, the positive gains were significantly maintained by the treatment group at the follow-up. The current study suggests that rational-emotive behavior therapy program can be effective for dealing with burnout syndrome among the population of undergraduates in Nigeria. Further clinical evaluation is needed.

The Canadian Consensus Working Group has updated its evaluation of the literature pertaining to statin intolerance and adverse effects. This overview introduces a pragmatic definition of statin intolerance (goal-inhibiting statin intolerance) that emphasizes the effects of symptoms on achieving nationally vetted goals in patients fulfilling indications for lipid-lowering therapy and cardiovascular risk reduction. The Canadian Consensus Working Group provides a structured framework for avoiding, evaluating and managing goal-inhibiting statin intolerance. Particularly difficult practice situations are reviewed, including management in young and elderly individuals, and in athletes and labourers. Finally, targeted at specialty practitioners, more detailed analyses of specific but more unusual adverse effects ascribed to statins are updated including evidence regarding new-onset diabetes, cognitive dysfunction, cataracts, and the rare but important immune-mediated necrotizing myopathy.

This study examined the effectiveness of rational emotive behavior coaching (REBC) on occupational stress and work ability in a sample of electronics workshop instructors in Nigeria. A pretest-posttest control group design was used. The participants were 108 electronics workshop instructors in technical colleges in the south-east of Nigeria who met the study inclusion criteria. Data were collected using 3 questionnaires and analyzed using a repeated measure analysis of variance and Mann-Whitney U test. REBC led to a significant reduction in occupational stress experienced by the electronics workshop instructors in the REBC group compared to their counterparts in the waitlist control group. Furthermore, the scores for occupation-related irrational beliefs of the instructors in the REBC group were significantly lower than those in the waitlist control group at the end of the coaching intervention. The work ability of the REBC group was significantly better than that of the waitlist control group. Finally, the effects in the REBC group were significantly sustained at 3-month follow-up. REBC is a time-efficient and solution-focused therapeutic modality for assisting occupationally stressed employees in a Nigerian setting. REBC can be used for improving and maintaining work ability of workers. The researchers hope that occupational health professionals and health counselors would extend this approach to tackle psychological issues limiting employees' effectiveness and performance in the Nigerian work environment and in other countries.

How to work with dreams in psychodrama: developmental therapy from an existential-dialectical viewpoint.

PubMed

Verhofstadt-Denève, L M

1995-07-01

As Moreno has shown, the method of psychodrama can be effectively used to work on dreams. The first part of this article describes the theoretical framework. Special reference is made to a personality model based on self-reflection in relation to dialectic processes, existential questions, self-evaluations, and personality development. The theoretical introduction is followed by a description of the basic elements, techniques, and stages associated with classic psychodrama and psychodramatic dream work. After situating this approach in the wider context of dream analysis in the field of group therapy, the different stages of the working model are illustrated by means of a "dream session" conducted with an adolescent therapy group. Finally the session is analyzed from the perspective of a number of basic Morenian tenets and from the point of view of developmental therapy.

Defensive Practice as ‘Fear-Based’ Practice: Social Work's Open Secret?

PubMed Central

Whittaker, Andrew; Havard, Tirion

2016-01-01

Defensive practice has received attention through the Munro review of child protection, which has identified that current organisational cultures increase the likelihood of defensive practice. Whilst the wider socio-political climate that gives rise to defensive practice has been explored within the literature, little attention has been paid to the everyday realities of defensive practice. This paper reports the findings of a study into final year social work students' attitudes towards defensive practice within social work. Three focus groups were completed with a total of ninety final-year students that collected qualitative and quantitative data using interactive software. This paper examines how participants perceived defensive practice, both in general and when faced with real-life vignettes. Participants distinguished between pro-active behaviour (sins of commission) and passive behaviour (sins of omission), generally regarding the latter as less serious because it was less tangible and easier to attribute to more positive motives. Whilst the literature identifies defensive practice as deliberate behaviour, the focus group discussions suggest that it is a subtler and less conscious process. Whilst there was there was a general consensus about the nature of defensive practice, there was considerable disagreement about specific vignettes and several competing explanations are explored.

OBJECTIVE/PARTICIPANTS: This report describes a project undertaken by three final (4th) year occupational therapy undergraduate students from the University of Sydney, Australia, in their final fieldwork placement. The project involved women from a Chinese background who worked on market gardens across the Sydney Basin. Its purpose was to identify musculoskeletal risks in the work environment and work practices of a selected group of seven Cantonese-speaking women working on market gardens in the Western Sydney region. The approaches used in the project reflected a risk management approach, and involved background research, initial interviews, task analysis, hazard identification, risk assessment, data analysis, identification of key issues, and developing recommendations, in collaboration with participants and consultation with professionals. The key issues identified as contributing factors to musculoskeletal pain and injuries were: (1) work practices (long work hours, repetitive work); (2) biomechanical factors (repetitive and sustained work postures, poor manual handling practices) and limited training; (3) ergonomics of the equipment used; (4) fatigue. Two priority areas for intervention were identified: (1) pain management, and (2) preventative strategies (improving both the work environment and work practices). Recommendations were made in collaboration with the women, and in consultation with health professionals.

The purpose of this study was to evaluate the canal isthmus debridement efficacy of a new modified EndoVac (Discus Dental, Culver City, CA) irrigation protocol in comparison with EndoVac, passive ultrasonic irrigation (PUI), and conventional needle irrigation in mesial roots of mandibular molars. The mesial roots of 64 extracted mandibular molars mounted in resin using Kuttler's endodontic cube, sectioned at 2 and 4 mm from the working length, were randomly divided into 4 groups (n = 16): group 1: Max-I-Probe (Dentsply Tulsa Dental, York, PA), group 2: EndoVac (EVI), group 3: modified EndoVac, and group 4: PUI. The specimens were reassembled and instrumented. A standard irrigation protocol was used during cleaning and shaping and final irrigation with the 4 irrigation/agitation techniques. Images of the isthmus region were taken before and after cleaning and shaping and after final irrigation. The percentage reduction of debris in the isthmus region was calculated by using the software program Image J (v1.43; National Institutes of Health, Bethesda, MD). Intergroup analysis was performed using the Kruskal Wallis and Mann-Whitney U tests. Intragroup analysis was performed using Friedman and Wilcoxon signed rank tests. The level of significance was set at P < .05. Intragroup analysis revealed a statistically significant difference in the percentage reduction of debris after cleaning and shaping and after final irrigation protocol in all the groups (P < .001). The final irrigation protocol produced significantly cleaner canal isthmuses in all the groups (P < .001). On intergroup analysis, the modified EVI group performed significantly better than the other groups. The EVI and PUI groups performed better than the Max-I-Probe group. There was no statistical significance between the EVI and PUI groups. Canal isthmuses were significantly cleaner with the modified EndoVac irrigation technique when compared with the cleanliness seen with the other irrigation systems.

NASA's Earth Science Data Systems Working Groups (ESDSWG) was created over 10 years ago. The role of the ESDSWG is to make recommendations relevant to NASA's Earth science data systems from users' experiences. Each group works independently focusing on a unique topic. Participation in ESDSWG groups comes from a variety of NASA-funded science and technology projects, including MEaSUREs and ROSS. Participants include NASA information technology experts, affiliated contractor staff and other interested community members from academia and industry. Recommendations from the ESDSWG groups will enhance NASA's efforts to develop long term data products. The Airborne Metadata Working Group is evaluating the suitability of the current Common Metadata Repository (CMR) and Unified Metadata Model (UMM) for airborne data sets and to develop new recommendations as necessary. The overarching goal is to enhance the usability, interoperability, discovery and distribution of airborne observational data sets. This will be done by assessing the suitability (gaps) of the current UMM model for airborne data using lessons learned from current and past field campaigns, listening to user needs and community recommendations and assessing the suitability of ISO metadata and other standards to fill the gaps. The Time Series Working Group (TSWG) is a continuation of the 2015 Time Series/WaterML2 Working Group. The TSWG is using a case study-driven approach to test the new Open Geospatial Consortium (OGC) TimeseriesML standard to determine any deficiencies with respect to its ability to fully describe and encode NASA earth observation-derived time series data. To do this, the time series working group is engaging with the OGC TimeseriesML Standards Working Group (SWG) regarding unsatisfied needs and possible solutions. The effort will end with the drafting of an OGC Engineering Report based on the use cases and interactions with the OGC TimeseriesML SWG. Progress towards finalizing recommendations will be presented at the meeting.

To demonstrate the effectiveness of medical-grade stainless steel Water Works Douching Device for treating abnormal vaginal odor in comparison with a commercially available over-the-counter plastic douching device. In a multicenter study, 140 women with perceived vaginal odor with no vaginal infection were randomized to either Water Works or control group in a 1:1 ratio and were douched daily for 4 weeks. A visual analog scale (VAS) was used to assess the intensity of vaginal odor. Primary outcome included subject assessment of odor improvement and Nugent Gram stain score of vaginal secretions. Secondary outcome compared the efficacy and safety of Water Works with control douching device. Each patient underwent baseline, week 2, and week 4 visits. The final analytic sample consisted of 96 women. Success score at 4 weeks was 78% for the Water Works group and 38.5% for the control group. Mean VAS was significantly reduced, and Nugent and Lactobacillus scores were maintained in both groups. In the Water Works group, VAS was reduced from 7.3 ± 0.3 to 1.8 ± 0.6 (p < .001) after 4 weeks. In the control group, baseline versus 4 weeks VAS was 7.2 ± 0.3 and 3.4 ± 0.8 (p < .003). Women reported significant reduction of vaginal odor after douching with water for 4 weeks without any alteration of vaginal flora. The Water Works Douching Device was superior to over- the-counter device in reducing vaginal odor.

Physical samples are integral to much of the research conducted by geoscientists. The samples used in this research are often obtained at significant cost and represent an important investment for future research. However, making information about samples - whether considered data or metadata - available for researchers to enable discovery is difficult: a number of key elements related to samples are difficult to characterize in common ways, such as classification, location, sample type, sampling method, repository information, subsample distribution, and instrumentation, because these differ from one domain to the next. Unifying these elements or developing metadata crosswalks is needed. The iSamples (Internet of Samples) NSF-funded Research Coordination Network (RCN) is investigating ways to develop these types of interoperability and crosswalks. Within the iSamples RCN, one of its working groups, WG1, has focused on the metadata related to physical samples. This includes identifying existing metadata standards and systems, and how they might interoperate with the International Geo Sample Number (IGSN) schema (schema.igsn.org) in order to help inform leading practices for metadata. For example, we are examining lifecycle metadata beyond the IGSN `birth certificate.' As a first step, this working group is developing a list of relevant standards and comparing their various attributes. In addition, the working group is looking toward technical solutions to facilitate developing a linked set of registries to build the web of samples. Finally, the group is also developing a comparison of sample identifiers and locators. This paper will provide an overview and comparison of the standards identified thus far, as well as an update on the technical solutions examined for integration. We will discuss how various sample identifiers might work in complementary fashion with the IGSN to more completely describe samples, facilitate retrieval of contextual information, and access research work on related samples. Finally, we welcome suggestions and community input to move physical sample unique identifiers forward.

Assessment of a novel group-centered testing schema in an upper-level undergraduate molecular biotechnology course.

Providing students with assignments that focus on critical thinking is an important part of their scientific and intellectual development. However, as class sizes increase, so does the grading burden, prohibiting many faculty from incorporating critical thinking assignments in the classroom. In an effort to continue to provide our students with meaningful critical thinking exercises, we implemented a novel group-centered, problem-based testing scheme. We wanted to assess how performing critical thinking problem sets as group work compares to performing the sets as individual work, in terms of student attitudes and learning outcomes. During two semesters of our recombinant DNA course, students had the same lecture material and similar assessments. In the Fall semester, student learning was assessed by two collaborative take-home exams, followed immediately by individual, closed-book in-class exams on the same content, as well as a final cumulative exam. Student teams on the take-home exams were instructor-assigned, and each team turned in one collaborative exam. In the Spring semester, the control group of students were required to turn in their own individual take-home exams, followed by the in-class exams and final cumulative exam. For the majority of students, learning outcomes were met, regardless of whether they worked in teams. In addition, collaborative learning was favorably received by students and grading was reduced for instructors. These data suggest that group-centered, problem-based learning is a useful model for achievement of student learning outcomes in courses where it would be infeasible to provide feedback on individual critical thinking assignments due to grading volume.

Cognitive overload can inhibit learning, and cognitive load theory-based instructional design principles can be used to optimize learning situations. This study aims to investigate the effect of implementing cognitive load theory-based design principles in virtual reality simulation training of mastoidectomy. Eighteen novice medical students received 1 h of self-directed virtual reality simulation training of the mastoidectomy procedure randomized for standard instructions (control) or cognitive load theory-based instructions with a worked example followed by a problem completion exercise (intervention). Participants then completed two post-training virtual procedures for assessment and comparison. Cognitive load during the post-training procedures was estimated by reaction time testing on an integrated secondary task. Final-product analysis by two blinded expert raters was used to assess the virtual mastoidectomy performances. Participants in the intervention group had a significantly increased cognitive load during the post-training procedures compared with the control group (52 vs. 41 %, p  = 0.02). This was also reflected in the final-product performance: the intervention group had a significantly lower final-product score than the control group (13.0 vs. 15.4, p  < 0.005). Initial instruction using worked examples followed by a problem completion exercise did not reduce the cognitive load or improve the performance of the following procedures in novices. Increased cognitive load when part tasks needed to be integrated in the post-training procedures could be a possible explanation for this. Other instructional designs and methods are needed to lower the cognitive load and improve the performance in virtual reality surgical simulation training of novices.

This white paper represents a summary of work intended to lay the foundation for development of a climatological/agent model of climate-induced conflict. The paper combines several loosely-coupled efforts and is the final report for a four-month late-start Laboratory Directed Research and Development (LDRD) project funded by the Advanced Concepts Group (ACG). The project involved contributions by many participants having diverse areas of expertise, with the common goal of learning how to tie together the physical and human causes and consequences of climate change. We performed a review of relevant literature on conflict arising from environmental scarcity. Rather than simply reviewingmore » the previous work, we actively collected data from the referenced sources, reproduced some of the work, and explored alternative models. We used the unfolding crisis in Darfur (western Sudan) as a case study of conflict related to or triggered by climate change, and as an exercise for developing a preliminary concept map. We also outlined a plan for implementing agents in a climate model and defined a logical progression toward the ultimate goal of running both types of models simultaneously in a two-way feedback mode, where the behavior of agents influences the climate and climate change affects the agents. Finally, we offer some ''lessons learned'' in attempting to keep a diverse and geographically dispersed group working together by using Web-based collaborative tools.« less

An increasing number of retirees continue to work beyond retirement despite being eligible to retire. As the prevalence of chronic disease increases with age, working beyond retirement may go along with having a chronic disease. Working beyond retirement may be different for retirees with and without chronic disease. We aim to investigate whether demographic, socioeconomic and work characteristics, health and social factors predict working beyond retirement, in workers with and without a chronic disease. Employees aged 56-64 years were selected from the Study on Transitions in Employment, Ability and Motivation (N = 1125). Questionnaire data on demographic and work characteristics, health, social factors, and working beyond retirement were linked to registry data from Statistics Netherlands on socioeconomic characteristics. Separate prediction models were built for retirees with and without chronic disease using multivariate logistic regression analyses. Workers without chronic disease were more likely to work beyond retirement compared to workers with chronic disease (27% vs 23%). In retirees with chronic disease, work and health factors predicted working beyond retirement, while in retirees without a chronic disease, work, health and social factors predicted working beyond retirement. In the final model for workers with chronic disease, healthcare work, better physical health, higher body height, lower physical load and no permanent contract were positively predictive of working beyond retirement. In the final model for workers without chronic disease, feeling full of life and being intensively physically active for > = 2 days per week were positively predictive of working beyond retirement; while manual labor, better recovery, and a partner who did not support working until the statutory retirement age, were negatively predictive of working beyond retirement. Work and health factors independently predicted working beyond retirement in workers with and without chronic disease, whereas social factors only did so among workers without chronic disease. Demographic and socioeconomic characteristics did not independently contribute to prediction of working beyond retirement in any group. As prediction of working beyond retirement was more difficult among workers with a chronic disease, future research is needed in this group.

The capacity to work productively is a key component of health and emotional well-being. People who work in health care can be exposed to the fatigue of care. Compassion fatigue has been described as an occupational hazard specific to clinical work related severe emotional distress. In our study, we have evaluated compassion fatigue in a mental health group (47 psychiatric staff) and its relationship with inpatients (237 inpatients) affected by some psychiatric disorders. At baseline, the more significant data indicate a high percentage of Job Burnout and Compassion Fatigue in psychiatric nurses (respectively, 39.28%, 28.57%). Significant Compassion Fatigue percentage is present also in psychologist group (36.36%). Finally, in psychiatrists, the exposure to patients increased vicarious trauma (28.57%), but not job burnout. After a year of participation in Balint Groups, the psychiatric staff presented an overall reduction in total mean score in any administered scale (CBI: p<0.0000045; sCFs: (Vicarious Trauma: p<0.0288; Job Burnout: p<0.000001)). Thus, compassion fatigue causes concern among mental health professionals, and Balint Groups may represent a therapeutic strategy to help health professionals to face difficulties in challenging work environments.

Eighty-eight job titles were analyzed with the "ergonomic job analysis procedure" [Arbeitswissenschaftliche Erhebungsverfahren zur Tätigkeits-analyse abbreviated (AET) in German]. The objective was to classify the wide range of municipal jobs into homogeneous groups according to job demand and to provide better possibilities to study the relationships between work and health among the aging municipal working population. Altogether 216 items were classified. First, a hierarchical cluster analysis was made, and a dendrogram of the analyzed job titles was drawn. Second, a profile analysis was done in which the single items were grouped into 39 sum items, and a graphic profile was drawn. Finally, the stress factors were listed and drawn in ranking order. The cluster analysis formed 13 groups. Groups exposed to the highest stress factor level were kitchen supervisors, dentists, and physicians. More than 10 stress factors (greater than 50% of the maximum) were found in nursing, administration, installation, transport, and technical supervision.

Examining Exposure Assessment in Shift Work Research: A Study on Depression Among Nurses.

PubMed

Hall, Amy L; Franche, Renée-Louise; Koehoorn, Mieke

2018-02-13

Coarse exposure assessment and assignment is a common issue facing epidemiological studies of shift work. Such measures ignore a number of exposure characteristics that may impact on health, increasing the likelihood of biased effect estimates and masked exposure-response relationships. To demonstrate the impacts of exposure assessment precision in shift work research, this study investigated relationships between work schedule and depression in a large survey of Canadian nurses. The Canadian 2005 National Survey of the Work and Health of Nurses provided the analytic sample (n = 11450). Relationships between work schedule and depression were assessed using logistic regression models with high, moderate, and low-precision exposure groupings. The high-precision grouping described shift timing and rotation frequency, the moderate-precision grouping described shift timing, and the low-precision grouping described the presence/absence of shift work. Final model estimates were adjusted for the potential confounding effects of demographic and work variables, and bootstrap weights were used to generate sampling variances that accounted for the survey sample design. The high-precision exposure grouping model showed the strongest relationships between work schedule and depression, with increased odds ratios [ORs] for rapidly rotating (OR = 1.51, 95% confidence interval [CI] = 0.91-2.51) and undefined rotating (OR = 1.67, 95% CI = 0.92-3.02) shift workers, and a decreased OR for depression in slow rotating (OR = 0.79, 95% CI = 0.57-1.08) shift workers. For the low- and moderate-precision exposure grouping models, weak relationships were observed for all work schedule categories (OR range 0.95 to 0.99). Findings from this study support the need to consider and collect the data required for precise and conceptually driven exposure assessment and assignment in future studies of shift work and health. Further research into the effects of shift rotation frequency on depression is also recommended. © The Author(s) 2018.

The requirement for an allied health workforce is expanding as the global burden of disease increases internationally. To safely meet the demand for an expanded workforce of orthotist/prosthetists in Australia, competency based standards, which are up-to-date and evidence-based, are required. The aims of this study were to determine the minimum level for entry into the orthotic/prosthetic profession; to develop entry level competency standards for the profession; and to validate the developed entry-level competency standards within the profession nationally, using an evidence-based approach. A mixed-methods research design was applied, using a three-step sequential exploratory design, where step 1 involved collecting and analyzing qualitative data from two focus groups; step 2 involved exploratory instrument development and testing, developing the draft competency standards; and step 3 involved quantitative data collection and analysis - a Delphi survey. In stage 1 (steps 1 and 2), the two focus groups - an expert and a recent graduate group of Australian orthotist/prosthetists - were led by an experienced facilitator, to identify gaps in the current competency standards and then to outline a key purpose, and work roles and tasks for the profession. The resulting domains and activities of the first draft of the competency standards were synthesized using thematic analysis. In stage 2 (step 3), the draft-competency standards were circulated to a purposive sample of the membership of the Australian Orthotic Prosthetic Association, using three rounds of Delphi survey. A project reference group of orthotist/prosthetists reviewed the results of both stages. In stage 1, the expert (n = 10) and the new graduate (n = 8) groups separately identified work roles and tasks, which formed the initial draft of the competency standards. Further drafts were refined and performance criteria added by the project reference group, resulting in the final draft-competency standards. In stage 2, the final draft-competency standards were circulated to 56 members (n = 44 final round) of the Association, who agreed on the key purpose, 6 domains, 18 activities, and 68 performance criteria of the final competency standards. This study outlines a rigorous and evidence-based mixed-methods approach for developing and endorsing professional competency standards, which is representative of the views of the profession of orthotist/prosthetists.

Our research assessed the prevalence of secondary traumatic stress (STS) among mental health providers working with military patients. We also investigated personal, work-related, and exposure-related correlates of STS. Finally, using meta-analysis, the mean level of STS symptoms in this population was compared with the mean level of these symptoms in other groups. Participants (N = 224) completed measures of indirect exposure to trauma (i.e., diversity, volume, frequency, ratio), appraisal of secondary exposure impact, direct exposure to trauma, STS, and work characteristics. The prevalence of STS was 19.2%. Personal history of trauma, complaints about having too many patients, and more negative appraisals of the impact caused by an indirect exposure to trauma were associated with higher frequency of STS symptoms. A meta-analysis showed that the severity of intrusion, avoidance, and arousal symptoms of STS was similar across various groups of professionals indirectly exposed to trauma (e.g., mental health providers, rescue workers, social workers).

Camacho, Angela

2015-03-01

Physics in Colombia started to develop in the 70's as a research part of basic sciences with the acquisition, at that time, of large research equipments such as x-rays and EPR. Experimental work was soon supplemented by theoretical investigations, which led to the formation of research groups in condensed matter. In the early 80's existed such groups in five universities. In this report we present, after a short history of the main steps that guided the initial research subjects, the major areas already developed and the minor research groups that are in the stage of consolidation. Currently this type of work is done at least in 20 universities. We also show the actual numbers of researchers, publications, PhD students and laboratories discriminated in gender to complete an overview of Condensed Matter Physics in Colombia. Finally, we present a short review of the main theoretical issues that have been worked in the last decade focusing on low dimensional systems, their structural and optical properties

Peer-assisted learning (PAL) has become a well-accepted teaching method within medical education. However, descriptions of on-ward PAL programs are rare. A focus group analysis of a newly established PAL program on an internal medicine ward was conducted to provide insights into PAL teaching from a student perspective. To provide insights into students' experiences regarding their on-ward training with and without accompanying PAL tutors. A total of N=168 medical students in their sixth semester participated in the investigation (intervention group: N=88; control group: N=80). The intervention group took part in the PAL program, while the control group received standard on-ward training. There were seven focus groups with N=43 participants (intervention group: four focus groups, N=28 participants; control group: three focus groups, N=15 participants). The discussions were analyzed using content analysis. The intervention group emphasized the role of the tutors as competent and well-trained teachers, most beneficial in supervising clinical skills. Tutors motivate students, help them to integrate into the ward team, and provide a non-fear-based working relationship whereby students' anxiety regarding working on ward decreases. The control group had to rely on autodidactic learning strategies when neither supervising physicians nor final-year students were available. On-ward PAL programs represent a particularly valuable tool for students' support in training clinical competencies on ward. The tutor-student working alliance acts through its flat hierarchy. Nevertheless, tutors cannot represent an adequate substitute for experienced physicians.

These cases provide a good basis for discussions of scientific ethics, particularly with respect to the responsibilities of colleagues in collaborative projects. With increasing numbers of students working in cooperative or collaborative groups, there may be opportunities for more than just discussion—similar issues of responsibility apply to the members of such groups. Further, this is an area where, “no clear, widely accepted standards of behavior exist” (1). Thus there is an opportunity to point out to students that scientific ethics, like science itself, is incomplete and needs constant attention to issues that result from new paradigms such as collaborative research. Finally, each of us can resolve to pay more attention to the contributions we and our colleagues make to collaborative projects, applying to our own work no less critical an eye than we would cast on the work of those we don’t know at all.

Molecular dynamics simulation on adsorption of pyrene-polyethylene onto ultrathin single-walled carbon nanotube

NASA Astrophysics Data System (ADS)

Cai, Lu; Lv, Wenzhen; Zhu, Hong; Xu, Qun

2016-07-01

The mechanism of the adsorption of pyrene-polyethylene (Py-PE) onto ultrathin single-walled carbon nanotube (SWNT) was studied by using all-atom molecular dynamics (MD) simulations. We found that solvent polarity and pyrene group are two critical factors in the Py-PE decoration on ultrathin SWNT. Combined MD simulations with free energy calculations, our results indicate that larger solvent polarity can decrease the contribution of conformation entropy, but contributes little to the interaction energy, moreover, larger SWNT diameter can decrease the contribution of conformation entropy but lead to the increasing of the interaction energy. In polar organic solvent (N, N-Dimethylacetamide), the pyrene group plays a key role in the adsorption of Py-PE onto ultrathin SWNT, not only facilitates the spontaneous adsorption of Py-PE onto ultrathin SWNT, but also helps to form compact structure between themselves in the final adsorption states. While in aqueous solution, pyrene group no longer works as an anchor, but still affects a lot to the final adsorption conformation. Our present work provides detailed theoretical clue to understand the noncovalent interaction between aromatic segment appended polymer and ultrathin SWNT, and helps to explore the potential application of ultrathin SWNT in the fields of hybrid material, biomedical and electronic materials.

Working memory contributes to elevated motor activity in adults with ADHD: an examination of the role of central executive and storage/rehearsal processes.

Hudec, Kristen L; Alderson, R Matt; Kasper, Lisa J; Patros, Connor H G

2014-05-01

The relationship between working memory (WM) and objectively measured motor activity was examined in adults with ADHD and healthy controls (HCs). Thirty-five adults (ADHD = 20, HC = 15) were grouped using self-report and collateral-report measures in addition to a semistructured clinical interview. All participants completed control conditions with minimal WM demands, and separate phonological (PH) and visuospatial (VS) WM tasks with recall demands ranging from four to seven stimuli. The ADHD group exhibited significantly more motor activity relative to the HC group, and both groups exhibited greater activity during PH and VS WM tasks, relative to control conditions. Finally, the central executive (CE) and PH storage/rehearsal subsystems were associated with large-magnitude between-group differences in activity. Findings suggest that increased demands on WM, particularly the CE and PH storage/rehearsal, contribute to ADHD-related hyperactivity, though a portion of excessive motor activity in adults with ADHD may occur independently of WM demands.

Objective: Since 2011, the new national final examination in human medicine has been implemented in Switzerland, with a structured clinical-practical part in the OSCE format. From the perspective of the national Working Group, the current article describes the essential steps in the development, implementation and evaluation of the Federal Licensing Examination Clinical Skills (FLE CS) as well as the applied quality assurance measures. Finally, central insights gained from the last years are presented. Methods: Based on the principles of action research, the FLE CS is in a constant state of further development. On the foundation of systematically documented experiences from previous years, in the Working Group, unresolved questions are discussed and resulting solution approaches are substantiated (planning), implemented in the examination (implementation) and subsequently evaluated (reflection). The presented results are the product of this iterative procedure. Results: The FLE CS is created by experts from all faculties and subject areas in a multistage process. The examination is administered in German and French on a decentralised basis and consists of twelve interdisciplinary stations per candidate. As important quality assurance measures, the national Review Board (content validation) and the meetings of the standardised patient trainers (standardisation) have proven worthwhile. The statistical analyses show good measurement reliability and support the construct validity of the examination. Among the central insights of the past years, it has been established that the consistent implementation of the principles of action research contributes to the successful further development of the examination. Conclusion: The centrally coordinated, collaborative-iterative process, incorporating experts from all faculties, makes a fundamental contribution to the quality of the FLE CS. The processes and insights presented here can be useful for others planning a similar undertaking. PMID:26483853

Studies evaluating the return to sports and work after shoulder arthroplasty are rare, and there are no studies evaluating return to work after total shoulder arthroplasty (TSA). Patients undergoing TSA will be able to return to their preoperative sports levels and occupations. Case series; Level of evidence, 4. A total of 154 patients with 170 TSAs for primary glenohumeral arthritis were included. Two subgroups were formed: patients who had participated in sports during the 5 years before surgery (group 1; n = 105 [68%]) and patients who had never participated in sports (group 2; n = 49 [32%]). The return-to-work rate in patients who had not retired after surgery were also analyzed, as were responses to a survey. The mean age at the time of surgery was 71 years (range, 33-88 years) in group 1 and 76 years (range, 54-88 years) in group 2. Mean follow-up time was 6.2 years (range, 2.5-12.6 years). Fifty-seven patients (54%) in group 1 participated in sports right up to the time of surgery. All 57 (100%) returned to sports after surgery. A further 3 patients (3%) from group 1 resumed sporting activity after surgery; swimming was the most popular sport. No patient in group 2 started sports activity after shoulder replacement surgery. Many of the patients, 14% of the entire group, had retired by final follow-up because of TSA. Fourteen percent of patients in group 1 and group 2 were pursuing their work at the time of most recent follow-up. Thirty patients of the entire cohort (19.5%) had to change their occupations because of surgery. Patients who participated in sports before TSA were successfully able to return to sports activities after surgery. Patients who did not participate in sports just before surgery were unlikely to start sports after surgery. Fourteen percent of the entire cohort was able to return to work after surgery. © 2014 The Author(s).

To explore the attitudes of Australian medical students to the balance between work, family and other aspects of lifestyle, within a broader exploration of the issues that they regard as important to their decisions about future career. Qualitative study using semistructured focus groups and individual interviews. The three medical schools in New South Wales and a national conference for students interested in rural practice. First- and final-year medical students who volunteered for focus groups held between March and August 2002 (82 students in 10 groups) or for individual interviews held between July and December 2003 (48 students). Emergent themes relating to the balance of work, family and other aspects of lifestyle. Most students referred to a balance of work, family and lifestyle as an important factor in their career decisions. While indicating they were committed to medicine, they were unwilling to work to the exclusion of all else. Most saw family commitments as a high priority, and many saw "time out" as important in maintaining their health. Female students spoke of part-time work as essential for future happiness, while some male students expressed a preference for working part-time. They would seek to achieve balance by choosing to work in disciplines, locations and structures where limited-hours work is available, and would negotiate support from their partners and parents in caring for children. It is important that the medical profession continue to develop working and training structures that allow a balance of work, family and lifestyle.

Nuclear Forensics: Report of the AAAS/APS Working Group

NASA Astrophysics Data System (ADS)

Tannenbaum, Benn

2008-04-01

This report was produced by a Working Group of the American Physical Society's Program on Public Affairs in conjunction with the American Association for the Advancement of Science Center for Science, Technology and Security Policy. The primary purpose of this report is to provide the Congress, U.S. government agencies and other institutions involved in nuclear forensics with a clear unclassified statement of the state of the art of nuclear forensics; an assessment of its potential for preventing and identifying unattributed nuclear attacks; and identification of the policies, resources and human talent to fulfill that potential. In the course of its work, the Working Group observed that nuclear forensics was an essential part of the overall nuclear attribution process, which aims at identifying the origin of unidentified nuclear weapon material and, in the event, an unidentified nuclear explosion. A credible nuclear attribution capability and in particular nuclear forensics capability could deter essential participants in the chain of actors needed to smuggle nuclear weapon material or carry out a nuclear terrorist act and could also encourage states to better secure such materials and weapons. The Working Group also noted that nuclear forensics result would take some time to obtain and that neither internal coordination, nor international arrangements, nor the state of qualified personnel and needed equipment were currently enough to minimize the time needed to reach reliable results in an emergency such as would be caused by a nuclear detonation or the intercept of a weapon-size quantity of material. The Working Group assesses international cooperation to be crucial for forensics to work, since the material would likely come from inadequately documented foreign sources. In addition, international participation, if properly managed, could enhance the credibility of the deterrent effect of attribution. Finally the Working Group notes that the U.S. forensics capability involved a number of agencies and other groups that would have to cooperate rapidly in an emergency and that suitable exercises to ensure such cooperation were needed.

Working time use and division of labour among nurses and health-care workers in hospitals - a systematic review.

2016-11-01

This systematic review aimed to synthesise the existing evidence of working time use and the division of labour among nurses and health-care workers in hospital wards. The environment of nursing work is changing. Health systems are becoming more complex and costly, and highly skilled health-care professionals are transferring to new, more demanding tasks. Changes require a division of labour that is based on the efficient use of working time. Sixteen studies were identified for the final analysis through a systematic search. The use of working time was examined mainly through six categories: direct care, indirect care, documentation, unit-related work, personal time and non-nursing duties. The division of labour was examined from the perspective of different occupational groups. Despite nurses' different educational backgrounds, certain similarities could be observed. All working groups seem to spend less than half of their working time in direct patient care. Nurse managers could influence the increasing nursing workload by supporting the right division of labour and focusing the nurses' working time use so that it benefits the patient. © 2016 John Wiley & Sons Ltd.

2014-01-01

This study compared elderly hearing aid (EHA) users and elderly normal-hearing (ENH) individuals on identification of auditory speech stimuli (consonants, words, and final word in sentences) that were different when considering their linguistic properties. We measured the accuracy with which the target speech stimuli were identified, as well as the isolation points (IPs: the shortest duration, from onset, required to correctly identify the speech target). The relationships between working memory capacity, the IPs, and speech accuracy were also measured. Twenty-four EHA users (with mild to moderate hearing impairment) and 24 ENH individuals participated in the present study. Despite the use of their regular hearing aids, the EHA users had delayed IPs and were less accurate in identifying consonants and words compared with the ENH individuals. The EHA users also had delayed IPs for final word identification in sentences with lower predictability; however, no significant between-group difference in accuracy was observed. Finally, there were no significant between-group differences in terms of IPs or accuracy for final word identification in highly predictable sentences. Our results also showed that, among EHA users, greater working memory capacity was associated with earlier IPs and improved accuracy in consonant and word identification. Together, our findings demonstrate that the gated speech perception ability of EHA users was not at the level of ENH individuals, in terms of IPs and accuracy. In addition, gated speech perception was more cognitively demanding for EHA users than for ENH individuals in the absence of semantic context. PMID:25085610

Evaluation of a Final Year Work-shadowing Attachment

McKavanagh, Peter; Boohan, Mairead; Savage, Maurice; McCluskey, David; McKeown, Pascal

2012-01-01

The transition from medical student to junior doctor is well recognised to be a difficult and stressful period. To ease this transition, most UK universities have a work-shadowing period (WSP), during which students can learn practical skills needed for forthcoming employment. The aim of this study was to evaluate the WSP at Queen’s University Belfast, and gain the views of both students and Foundation Programme Supervisors and Directors (FPSDs). The study utilised both qualitative (focus groups) and quantitative (questionnaires) approaches. The FPSDs completed a specific questionnaire designed for this study, while the students completed the university’s internal quality assurance questionnaire. Twenty-eight of the 37 (76%) FPSDs and 106 / 196 (54%) students completed the questionnaires. Focus groups were conducted with up to 10 students in each group in both a regional centre and a district general hospital at the start and the end of the WSP as well as 8 weeks into working life. The transcripts of the focus groups were analysed and themes identified. A number of deficiencies with the current WSP were identified, including concerns about the use of log books, the timing of the attachment and relatively low levels of supervision provided by senior hospital staff members. As a result, students felt unprepared for commencing work, with particular mention given to medical emergencies, prescribing, and the emotional aspects of the job. A number of recommendations are made, including the need for more senior input to ensure better student attendance, participation and clinical interaction. Furthermore, students should be offered additional supervised responsibility for delivery of patient care and more experiential learning with respect to drug prescribing and administration. The study also suggests that more needs to be done to help ease the emotional and psychological stresses of the early FY1 period. These issues have been resolved to a large extent with the introduction of the new final year Student Assistantship module in the academic year 2010-2011. PMID:23526851

Mother's home healthcare: emotion work when a child has cancer.

PubMed

Clarke, Juanne N

2006-01-01

Home healthcare work, involving physical labor, nursing care, medical monitoring, administrative, planning and accounting, advocacy and emotion work, is unpaid and largely invisible. This article, based on focus group interviews with mothers whose children have had cancer, describes one part of their home healthcare labor, their emotion work. Specifically, it examines how mothers: manage the moral imperatives of mothering; think about and try to manage the strong feelings, particularly of fear and uncertainty that they often have when their children are ill with cancer; work to understand and maintain their marital relationships; the strategies that seemed to help; and finally, the self-transformation that many mothers experience. The article concludes with a discussion of the substantive, theoretical, research, and policy implications of emotion work in the provision of home healthcare work.

Working memory deficits in boys with attention deficit/hyperactivity disorder (ADHD): An examination of orthographic coding and episodic buffer processes.

Alderson, R Matt; Kasper, Lisa J; Patros, Connor H G; Hudec, Kristen L; Tarle, Stephanie J; Lea, Sarah E

2015-01-01

The episodic buffer component of working memory was examined in children with attention deficit/hyperactivity disorder (ADHD) and typically developing peers (TD). Thirty-two children (ADHD = 16, TD = 16) completed three versions of a phonological working memory task that varied with regard to stimulus presentation modality (auditory, visual, or dual auditory and visual), as well as a visuospatial task. Children with ADHD experienced the largest magnitude working memory deficits when phonological stimuli were presented via a unimodal, auditory format. Their performance improved during visual and dual modality conditions but remained significantly below the performance of children in the TD group. In contrast, the TD group did not exhibit performance differences between the auditory- and visual-phonological conditions but recalled significantly more stimuli during the dual-phonological condition. Furthermore, relative to TD children, children with ADHD recalled disproportionately fewer phonological stimuli as set sizes increased, regardless of presentation modality. Finally, an examination of working memory components indicated that the largest magnitude between-group difference was associated with the central executive. Collectively, these findings suggest that ADHD-related working memory deficits reflect a combination of impaired central executive and phonological storage/rehearsal processes, as well as an impaired ability to benefit from bound multimodal information processed by the episodic buffer.

An integrator final exam at the end of the engineering degrees to evaluate the acquired competences

Perdigones, A.; Sánchez, E.; Valiño, V.; Tarquis, A. M.

2010-05-01

In the last decade strong changes in the design of university degrees have occurred in Spain, affecting real competences acquired by graduates. The new degrees often provide students greater freedom in shaping their curriculum which results in many cases in a problem for their training. In engineering degrees of Spain, the final project, that allows to know the integrated skills of the students in engineering subjects, is not compulsory anymore; it can be substituted for other specific types of work that often do not involve skills valued by the companies of the industrial sector. This situation may create doubts about the real competences of the graduates. In the present study, a final exam (voluntary) has been carried out during three years to assess competences in engineering students in the last course of the degree in agricultural engineering (diploma of five years) and agricultural technical engineering (diploma of three years) at the Polytechnic University of Madrid (Spain). They took part 132 students in the years 2006, 2007 and 2008. The exam had a common format, with three parts assessing skills in construction, machinery and electrical installations. The results showed the evolution in the training of students, and the relationship between skills acquired and late differences in the learning process. The most important conclusions were that the attainment levels was lower than expected, but generally consistent with the training received by each group of students. In particular, the low number of hours of subjects in electrical installations in certain groups of students was evident when evaluating the skills acquired. The results indicated that they aim to increase the number of hours in certain subjects and groups of students, if a graduate is to get qualified. The authors recommend an examination similar to the raised, integrator type, in all programs that do not have any overall final assessment in order to conduct a quality control of graduates; this approach has the advantage that graduates may also obtain an additional final certificate with their level of competences towards their future professional work.

The goal of this document is to update the original OARSI recommendations specifically for the design, conduct, and reporting of clinical trials that target symptom or structure modification among individuals with knee osteoarthritis (OA). To develop recommendations for the design, conduct, and reporting of clinical trials for knee OA we initially drafted recommendations through an iterative process. Members of the working group included representatives from industry and academia. After the working group members reviewed a final draft, they scored the appropriateness for recommendations. After the members voted we calculated the median score among the nine members of the working group who completed the score. The document includes 25 recommendations regarding randomization, blocking and stratification, blinding, enhancing accuracy of patient-reported outcomes (PRO), selecting a study population and index knee, describing interventions, patient-reported and physical performance measures, structural outcome measures, biochemical biomarkers, and reporting recommendations. In summary, the working group identified 25 recommendations that represent the current best practices regarding clinical trials that target symptom or structure modification among individuals with knee OA. These updated recommendations incorporate novel technologies (e.g., magnetic resonance imaging (MRI)) and strategies to address the heterogeneity of knee OA.

As access to antiretroviral therapy (ART) has grown in Africa, attention has turned to evaluating the socio-economic impacts of ART. One key issue is the extent to which improvements in health resulting from ART allows individuals to return to work and earn income. Improvements in health from ART may also be associated with reduced impaired presenteeism, which is the loss of productivity when an ill or disabled individual attends work but accomplishes less at his or her usual tasks or shifts to other, possibly less valuable, tasks. Longitudinal data for this analysis come from company payroll records for 97 HIV-infected tea estate workers (the index group, 56 women, 41 men) and a comparison group of all workers assigned to the same work teams (n = 2485, 1691 men, 794 women) for a 37-month period covering two years before and one year after initiating ART. We used nearest neighbour matching methods to estimate the impacts of HIV/AIDS and ART on three monthly employment outcomes for tea estate workers in Kenya--days plucking tea, days assigned to non-plucking assignments, and kilograms harvested when plucking. The female index group worked 30% fewer days plucking tea monthly than the matched female comparison group during the final 9 months pre-ART. They also worked 87% more days on non-plucking assignments. While the monthly gap between the two groups narrowed after beginning ART, the female index group worked 30% fewer days plucking tea and about 100% more days on non-plucking tasks than the comparison group after one year on ART. The male index group was able to maintain a similar pattern of work as their comparison group except during the initial five months on therapy. Significant impaired presenteeism continued to exist among the female index group after one year on ART. Future research needs to explore further the socio-economic implications of HIV-infected female workers on ART being less productive than the general female workforce over sustained periods of time.

The aim of this research was to identify short-term career aspirations and goals of final-year dental students at a London dental school and the perceived factors that influenced these aspirations. Two methods were used to collect data on final-year students' short-term career plans and influences. Qualitative data were collected through focus groups and analysed using 'framework methodology'. These findings informed a questionnaire survey of all students at the end of their final undergraduate year. Data were entered into and analysed using a statistical software package. Thirty-five students participated in focus groups, with recruitment continuing until data were saturated. Ninety per cent (n=126) of the total population (140) responded to the questionnaire survey; the majority were Asian (70%), female (58%), and aged 23 years (59%). Short-term professional expectations focused around 'achieving professional status within a social context', 'gaining professional experience', 'developing independence' and 'achieving financial stability'. 'Achieving financial stability' was ranked as the most important influence in decision-making about their career in the short term (77%), followed by 'balance of work and other aspects of life' (75%) and 'good lifestyle' (75%). Four out of ten intended to work towards membership of a Royal College and/or becoming a specialist. Proximity to family (81%) and friends (79%) was an important or very important influence on location in the short term. Asian students were significantly more likely to rate 'proximity to family' (p=0.042), working in an 'urban area' (p=0.001) and 'opportunities for private care' (p=0.043) of greater importance than their White counterparts. Short-term aspirations involve 'achieving professional status within a social context', and personal, social, professional and financial goals. Location of future practice was significantly associated with ethnicity.

This article aimed to present a basic questionnaire and minimum methodological criteria for consideration in future Surveys on Working Conditions, Employment, and Health in Latin America and the Caribbean. A virtual and face-to-face consensus process was conducted with participation by a group of international experts who used the surveys available up until 2013 as the point of departure for defining the proposal. The final questionnaire included 77 questions grouped in six dimensions: socio-demographic characteristics of workers and companies; employment conditions; working conditions; health status; resources and preventive activities; and family characteristics. The minimum methodological criteria feature the interviewee's home as the place for the interview and aspects related to the quality of the fieldwork. These results can help improve the comparability of future surveys in Latin America and the Caribbean, which would in turn help improve information on workers' heath in the region.

2012-12-01

This study prospectively evaluated compliance and outcomes after rotator cuff repair in patients with and without Workers' Compensation claims. From December 2007 to January 2010, 42 consecutive patients with Workers' Compensation claims (Work Comp group), and 50 consecutive patients without a Workers' Compensation claim (non-Work Comp group) underwent arthroscopic rotator cuff repair and were enrolled in this study. Compliance with a postoperative protocol of shoulder immobilization and physical therapy was documented. Patients were monitored clinically for a minimum of 12 months. Noncompliance with protocol was documented in 22 of 42 patients (52%) in the Work Comp group compared with 2 of 50 (4%) in the non-Work Comp group (P < .001). The Work Comp group had less improvement in preoperative to postoperative outcome scores for the American Shoulder and Elbow Surgeons (ASES) score (40.4 to 60.1), Simple Shoulder Test (SST) score (3.9 to 6.0) and visual analog scale (VAS) for pain (7.0 to 3.5) compared with the non-Work Comp group (ASES, 41.7 to 89.2; SST, 4.3 to 10.7; VAS, 6.2 to 0.35; P < .0001). The compliant Work Comp patients had more favorable results in final outcome scores (ASES, 73.1; SST, 7.9; VAS, 1.5) than noncompliant Work Comp patients (ASES, 48.4; SST, 4.3; VAS, 5.3; P < .0001). Patients with Workers' Compensation claims demonstrated a high rate of postoperative noncompliance (52%) compared with patients without Workers' Compensation claims (4%) after rotator cuff repair. Those Workers' Compensation patients who had no evidence of noncompliance had significant improvements and more favorable outcomes than the noncompliant Workers' Compensation patients.

2002-09-01

The purpose of this semester-long study was to investigate the effect of replacing traditional lecture with cooperative group problem-solving sessions in a junior-level quantitative analysis course. The control and treatment groups had the same instructor, met on the same day, had the same reading assignments, and had common exams. The instructor worked sample problems for the control group. In the treatment group, students were assigned to heterogeneous cooperative groups of 4. The groups solved problems presented on an overhead that were the same or equivalent in content and number to those used in the control group. Students were responsible for making sure that all members of the group could work each problem. The students' reasoning abilities were measured by the Test of Logical Thinking (TOLT). Groups were compared on quiz, exam, final, and course grades. Other data included attitudinal surveys, observations, field notes, interviews, and open-response evaluations. No significant differences were found in content measures. Differences were found in the number of students dropping the course and in the attitudes and perceptions of the two groups. Qualitative measures support a number of assertions concerning more positive attitudes and lower withdrawal rates in the treatment group, and a case for mixed delivery modes.

Harriet Brooks: Canada's First Woman Physicist

2004-03-01

During those early halcyon days of the study of radioactivity, one young Canadian woman, Harriet Brooks, joined Ernest Rutherford's group as his first research student. Later, she joined J.J. Thomson's group in Cambridge and, finally, Marie Curie's group in Paris. During her short research career, she made several important contributions to science. She investigated the nature of 'emanation' from radium; discovered that radioactive substances could undergo successive decay; and first reported the recoil of the radioactive atom. Much of this research was published under her name alone though Rutherford made extensive reference to her discoveries in his Bakerian lecture of 1904. Brooks life is of interest not only in what she accomplished, but also in the challenges she faced as a pioneering woman scientist in the early part of the twentieth century. In the presentation we will blend the account of her life and work with the societal context. This work was accomplished jointly with Marelene F. Rayner-Canham.

The world is rapidly running out of IPv4 addresses; the number of IPv6 end systems connected to the internet is increasing; WLCG and the LHC experiments may soon have access to worker nodes and/or virtual machines (VMs) possessing only an IPv6 routable address. The HEPiX IPv6 Working Group has been investigating, testing and planning for dual-stack services on WLCG for several years. Following feedback from our working group, many of the storage technologies in use on WLCG have recently been made IPv6-capable. This paper presents the IPv6 requirements, tests and plans of the LHC experiments together with the tests performed on the group's IPv6 test-bed. This is primarily aimed at IPv6-only worker nodes or VMs accessing several different implementations of a global dual-stack federated storage service. Finally the plans for deployment of production dual-stack WLCG services are presented.

2014-01-01

Object segmentation of unknown objects with arbitrary shape in cluttered scenes is an ambitious goal in computer vision and became a great impulse with the introduction of cheap and powerful RGB-D sensors. We introduce a framework for segmenting RGB-D images where data is processed in a hierarchical fashion. After pre-clustering on pixel level parametric surface patches are estimated. Different relations between patch-pairs are calculated, which we derive from perceptual grouping principles, and support vector machine classification is employed to learn Perceptual Grouping. Finally, we show that object hypotheses generation with Graph-Cut finds a globally optimal solution and prevents wrong grouping. Our framework is able to segment objects, even if they are stacked or jumbled in cluttered scenes. We also tackle the problem of segmenting objects when they are partially occluded. The work is evaluated on publicly available object segmentation databases and also compared with state-of-the-art work of object segmentation. PMID:24478571

Support groups for suicide survivors (those individuals bereaved following a suicide) are widely used, but little research evidence is available to determine their efficacy. This paper outlines the pressing public health need to conduct research and determine effective ways to identify and meet the needs of suicide survivors, particularly through survivor support groups. After describing the various approaches to survivor support groups, we explain the need for further research, despite the inherent challenges. Finally, we pose several questions for researchers to consider as they work with survivors to develop a research agenda that sheds more light on the experiences of survivors and the help provided by survivor support groups.

A comparison of hospital- and community-based mental health nurses: perceptions of their work environment and psychological health.

PubMed

Fielding, J; Weaver, S M

1994-06-01

This study compares hospital- (n = 67) and community-based (n = 55) mental health nurses in relation to their perceptions of the work environment and also their psychological health. Measures include: the General Health Questionnaire, the Maslach Burnout Inventory and the Work Environment Scale. The data, obtained from self-returned questionnaires, show that community nurses rated their work environments higher for the dimensions of Involvement, Supervisor Support, Autonomy, Innovation and Work Pressure. Hospital nurses saw their environments as being higher in (managerial) Control. There were no differences between the groups for the dimensions of Peer Cohesion, Task Orientation, Clarity or (physical) Comfort. Furthermore, there were no overall differences between the two groups in relation to psychological health, although the pattern of factors associated with emotional well-being differed. Finally, analyses of the community data revealed that those nurses with 'flexitime' arrangements evaluated their work environments less positively and showed higher levels of psychological strain than did those working 'fixed-time' schedules. The findings suggest that the hospital and community environments make different demands on nursing staff, and that this should be considered when organizing nursing services if stress is to be avoided.

International Standardization of the Clinical Dosimetry of Beta Radiation Brachytherapy Sources: Progress of an ISO Standard

NASA Astrophysics Data System (ADS)

Soares, Christopher

2006-03-01

In 2004 a new work item proposal (NWIP) was accepted by the International Organization for Standardization (ISO) Technical Committee 85 (TC85 -- Nuclear Energy), Subcommittee 2 (Radiation Protection) for the development of a standard for the clinical dosimetry of beta radiation sources used for brachytherapy. To develop this standard, a new Working Group (WG 22 - Ionizing Radiation Dosimetry and Protocols in Medical Applications) was formed. The standard is based on the work of an ad-hoc working group initiated by the Dosimetry task group of the Deutsches Insitiut für Normung (DIN). Initially the work was geared mainly towards the needs of intravascular brachytherapy, but with the decline of this application, more focus has been placed on the challenges of accurate dosimetry for the concave eye plaques used to treat ocular melanoma. Guidance is given for dosimetry formalisms, reference data to be used, calibrations, measurement methods, modeling, uncertainty determinations, treatment planning and reporting, and clinical quality control. The document is currently undergoing review by the ISO member bodies for acceptance as a Committee Draft (CD) with publication of the final standard expected by 2007. There are opportunities for other ISO standards for medical dosimetry within the framework of WG22.

This paper relates to the first phase one of a three-phase study. Phase 1 investigated and identified risk factors for work-related musculoskeletal disorders (WMSDs) in 26 'One Tambon One Product' (OTOP) groups working in the informal sector. Data was collected from 93 participants in Khangkoi District, Saraburi Province, Thailand during 2009-2010. Results of inspections and direct observations of work places and interviews of managers and workers showed risk factors related to posture, repetition, force and duration in the workers' operations and the application of a checklist revealed that the OTOP groups had simple work processes. A knowledge-attitude-practice survey of managers and workers indicated that there was a moderate to high awareness regarding ergonomics and occupational safety and health principles and approximately 15% of workers reported WMSDs at a moderate level, mainly associated with lower back and shoulder pains, due to protracted periods of sitting. Specific recommendations in response to OTOP conditions and needs were made. The second phase of the study involves a participatory ergonomics worksite intervention by a number of stakeholders and the final phase deals with an evaluation of the intervention and an establishment of guidelines for ergonomics programs for OTOP groups.

It has been well-established that discussion groups enhance student learning in large lecture courses. The goal of this study was to determine the impact of a discussion group program on the development of conceptual reasoning skills of students enrolled in a large lecture-format introductory biology course. In the discussion group, students worked on problems based on topics discussed in lecture. The program was evaluated using three assessment tools. First, student responses to pre- and posttests were analyzed. The test question asked the students to demonstrate the relationships between 10 different but related terms. Use of a concept map to link the terms indicated an advanced level of conceptual reasoning skills. There was a 13.8% increase in the use of concept maps from pre- to posttest. Second, the students took a Likert-type survey to determine the perceived impact of the program on their conceptual reasoning skills. Many of the students felt that the program helped them understand and use the main course concepts to logically solve problems. Finally, average exam grades increased as the semester progressed. The average final grade in the course was 75%. Students enrolled in the course the previous year (where the lecture component of the course did not assess or reflect student learning in the discussion group) had an average final grade of 69%. The results of this study demonstrate that the discussion group program improves the conceptual reasoning skills of students enrolled in a large lecture-format introductory biology course.

Final Report for DOE Grant DE-FG02-03ER25579; Development of High-Order Accurate Interface Tracking Algorithms and Improved Constitutive Models for Problems in Continuum Mechanics with Applications to Jetting

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

Puckett, Elbridge Gerry; Miller, Gregory Hale

Much of the work conducted under the auspices of DE-FG02-03ER25579 was characterized by an exceptionally close collaboration with researchers at the Lawrence Berkeley National Laboratory (LBNL). For example, Andy Nonaka, one of Professor Miller's graduate students in the Department of Applied Science at U. C. Davis (UCD) wrote his PhD thesis in an area of interest to researchers in the Applied Numerical Algorithms Group (ANAG), which is a part of the National Energy Research Supercomputer Center (NERSC) at LBNL. Dr. Nonaka collaborated closely with these researchers and subsequently published the results of this collaboration jointly with them, one article inmore » a peer reviewed journal article and one paper in the proceedings of a conference. Dr. Nonaka is now a research scientist in the Center for Computational Sciences and Engineering (CCSE), which is also part of the National Energy Research Supercomputer Center (NERSC) at LBNL. This collaboration with researchers at LBNL also included having one of Professor Puckett's graduate students in the Graduate Group in Applied Mathematics (GGAM) at UCD, Sarah Williams, spend the summer working with Dr. Ann Almgren, who is a staff scientist in CCSE. As a result of this visit Sarah decided work on a problem suggested by the head of CCSE, Dr. John Bell, for her PhD thesis. Having finished all of the coursework and examinations required for a PhD, Sarah stayed at LBNL to work on her thesis under the guidance of Dr. Bell. Sarah finished her PhD thesis in June of 2007. Writing a PhD thesis while working at one of the University of California (UC) managed DOE laboratories is long established tradition at UC and Professor Puckett has always encouraged his students to consider doing this. Another one of Professor Puckett's graduate students in the GGAM at UCD, Christopher Algieri, was partially supported with funds from DE-FG02-03ER25579 while he wrote his MS thesis in which he analyzed and extended work originally published by Dr. Phillip Colella, the head of ANAG, and some of his colleagues. Chris Algieri is now employed as a staff member in Dr. Bill Collins' Climate Science Department in the Earth Sciences Division at LBNL working with computational models of climate change. Finally, it should be noted that the work conducted by Professor Puckett and his students Sarah Williams and Chris Algieri and described in this final report for DOE grant # DE-FC02-03ER25579 is closely related to work performed by Professor Puckett and his students under the auspices of Professor Puckett's DOE SciDAC grant DE-FC02-01ER25473 An Algorithmic and Software Framework for Applied Partial Differential Equations: A DOE SciDAC Integrated Software Infrastructure Center (ISIC). Dr. Colella was the lead PI for this SciDAC grant, which was comprised of several research groups from DOE national laboratories and five university PI's from five different universities. In theory Professor Puckett tried to use funds from the SciDAC grant to support work directly involved in implementing algorithms developed by members of his research group at UCD as software that might be of use to Puckett's SciDAC CoPIs. (For example, see the work reported in Section 2.2.2 of this final report.) However, since there is considerable lead time spent developing such algorithms before they are ready to become `software' and research plans and goals change as the research progresses, Professor Puckett supported each member of his research group partially with funds from the SciDAC APDEC ISIC DE-FC02-01ER25473 and partially with funds from this DOE MICS grant DE-FC02-03ER25579. This has necessarily resulted in a significant overlap of project areas that were funded by both grants. In particular, both Sarah Williams and Chris Algieri were supported partially with funds from grant # DE-FG02-03ER25579, for which this is the final report, and in part with funds from Professor Puckett's DOE SciDAC grant # DE-FC02-01ER25473. For example, Sarah Williams received support from DE-FC02- 01ER25473 and DE-FC02-03ER25579, both while at UCD taking classes and writing her MS thesis and during the first year she was living in Berkeley and working at LBNL on her PhD thesis. In Chris Algieri's case he was at UCD during the entire time he received support from both grants. More specific details of their work are included in the report.« less

Can labour contract differences in health and work-related attitudes be explained by quality of working life and job insecurity?

PubMed

Wagenaar, Alfred F; Kompier, Michiel A J; Houtman, Irene L D; van den Bossche, Seth; Smulders, Peter; Taris, Toon W

We hypothesise that due to a lower quality of working life and higher job insecurity, the health and work-related attitudes of temporary workers may be less positive compared to permanent workers. Therefore, we aimed to (1) examine differences between contract groups (i.e. permanent contract, temporary contract with prospect of permanent work, fixed-term contract, temporary agency contract and on-call contract) in the quality of working life, job insecurity, health and work-related attitudes and (2) investigate whether these latter contract group differences in health and work-related attitudes can be explained by differences in the quality of working life and/or job insecurity. Data were collected from the Netherlands Working Conditions Survey 2008 (N = 21,639), and Hypotheses were tested using analysis of variance and cross-table analysis. Temporary work was associated with fewer task demands and lower autonomy and was more often passive or high-strain work, while permanent work was more often active work. Except for on-call work, temporary work was more insecure and associated with worse health and work-related attitude scores than permanent work. Finally, the quality of working life and job insecurity partly accounted for most contract differences in work-related attitudes but not in health. Especially agency workers have a lower health status and worse work-related attitudes. Job redesign measures regarding their quality of working life and job insecurity are recommended.

To improve science learning, science educators' teaching tools need to address two major criteria: teaching practice should mirror our current understanding of the learning process; and science teaching should reflect scientific practice. We designed a small-group learning (SGL) model for a fourth year university neurobiology course using these criteria and studied student achievement and attitude in five course sections encompassing the transition from individual work-based to SGL course design. All students completed daily quizzes/assignments involving analysis of scientific data and the development of scientific models. Students in individual work-based (Individualistic) sections usually worked independently on these assignments, whereas SGL students completed assignments in permanent groups of six. SGL students had significantly higher final exam grades than Individualistic students. The transition to the SGL model was marked by a notable increase in 10th percentile exam grade (Individualistic: 47.5%; Initial SGL: 60%; Refined SGL: 65%), suggesting SGL enhanced achievement among the least prepared students. We also studied student achievement on paired quizzes: quizzes were first completed individually and submitted, and then completed as a group and submitted. The group quiz grade was higher than the individual quiz grade of the highest achiever in each group over the term. All students – even term high achievers –could benefit from the SGL environment. Additionally, entrance and exit surveys demonstrated student attitudes toward SGL were more positive at the end of the Refined SGL course. We assert that SGL is uniquely-positioned to promote effective learning in the science classroom. PMID:21209910

Full recovery after gynecological surgery takes much longer than expected regardless of surgical technique or the level of invasiveness. After discharge, detailed convalescence recommendations are not provided to patients typically, and postoperative care is fragmented, poorly coordinated, and given only on demand. For patients, this contributes to irrational beliefs and avoidance of resumption of activities and can result in a prolonged sick leave. To develop an eHealth intervention that empowers gynecological patients during the perioperative period to obtain timely return to work (RTW) and prevent work disability. The intervention mapping (IM) protocol was used to develop the eHealth intervention. A literature search about behavioral and environmental conditions of prolonged sick leave and delayed RTW in patients was performed. Patients' needs, attitudes, and beliefs regarding postoperative recovery and resumption of work were identified through focus group discussions. Additionally, a literature search was performed to obtain determinants, methods, and strategies for the development of a suitable interactive eHealth intervention to empower patients to return to normal activities after gynecological surgery, including work. Finally, the eHealth intervention was evaluated by focus group participants, medical doctors, and eHealth specialists through questionnaires. Twenty-one patients participated in the focus group discussions. Sufficient, uniform, and tailored information regarding surgical procedures, complications, and resumption of activities and work were considered most essential. Knowing who to contact in case of mental or physical complaints, and counseling and tools for work reintegration were also considered important. Finally, opportunities to exchange experiences with other patients were a major issue. Considering the determinants of the Attitude-Social influence-self-Efficacy (ASE) model, various strategies based on a combination of theory and evidence were used, resulting in an eHealth intervention with different interactive functionalities including tailored convalescence recommendations and a video to communicate the most common pitfalls during the perioperative period to patients and employers. Fifteen patients in the focus groups, 11 physicians, and 3 eHealth specialists suggested points for improvement to optimize the usability of the eHealth intervention and judged it an approachable, appropriate, and attractive eHealth intervention to empower gynecological patients. The IM protocol was a useful method to develop an eHealth intervention based on both theory and evidence. All patients and stakeholders judged the eHealth intervention to be a promising tool to empower gynecological patients during the perioperative period and to help them to return to normal activities and work.

To describe, from the patient's point of view, the factors influencing the occupational trajectory of patients with systemic sclerosis (SSc). This was a qualitative study designed using grounded theory with constant comparison. Data were collected through semi-structured interviews with 14 patients who fulfilled the American College of Rheumatology or Leroy-Medsger criteria for SSc. Based on our interviews, we found that the occupational trajectory of patients with SSc is influenced by the continuous interplay between four groups of factors. The first group concerns the values patients attribute to work, including identity, normality, financial value, social contact, and structure. The meaning of these values and how they relate to each other underlies the desire to work. A second group of factors is those influencing the balance between daily life, work participation, and medical condition (e.g. job content, flexibility in organising work, and the willingness to ask for accommodations at work). The occupational trajectory is also influenced by external factors, including availability of support, know-ledge of the disease, pressure to work, contact with medical professionals, and existing regulations and the patient's knowledge about them. Finally, the occupational trajectory is influenced by personal factors, including socio-demographics, psychological assets, and disease- and work-related personal factors. The decisions patients with SSc take concerning work depend on an interplay between many factors and, especially, on the patients' personal interpretation of these factors. These need to be taken into account when helping patients with SSc determine their occupational trajectory.

Optical parametric amplifiers using chirped quasi-phase-matching (QPM) gratings offer the possibility of engineering the gain and group delay spectra. We give practical formulas for the design of such amplifiers. We consider linearly chirped QPM gratings providing constant gain over a broad bandwidth, sinusoidally modulated profiles for selective frequency amplification and a pair of QPM gratings working in tandem to ensure constant gain and constant group delay at the same time across the spectrum. Finally, the analysis is carried out in the frequency domain using Wentzel–Kramers–Brillouin analysis.

VLBI2010: An Overview

2010-01-01

The first concrete actions toward a next generation system for geodetic VLBI began in 2003 when the IVS initiated Working Group 3 to investigate requirements for a new system. The working group set out ambitious performance goals and sketched out initial recommendations for the system. Starting in 2006, developments continued under the leadership of the VLBI2010 Committee (V2C) in two main areas: Monte Carlo simulators were developed to evaluate proposed system changes according to their impact on IVS final products, and a proof-of-concept effort sponsored by NASA was initiated to develop next generation systems and verify the concepts behind VLBI2010. In 2009, the V2C produced a progress report that summarized the conclusions of the Monte Carlo work and outlined recommendations for the next generation system in terms of systems, analysis, operations, and network configuration. At the time of writing: two complete VLBI2010 signal paths have been completed and data is being produced; a number of VLBI2010 antenna projects are under way; and a VLBI2010 Project Executive Group (V2PEG) has been initiated to provide strategic leadership.

Consensus recommendations for the postmortem diagnosis of Alzheimer's disease. The National Institute on Aging, and Reagan Institute Working Group on Diagnostic Criteria for the Neuropathological Assessment of Alzheimer's Disease.

PubMed

1997-01-01

This report summarizes the consensus recommendations of a panel of neuropathologists from the United States and Europe to improve the postmortem diagnostic criteria for Alzheimer's disease. The recommendations followed from a two-day workshop sponsored by the National Institute on Aging (NIA) and the Ronald and Nancy Reagan Institute of the Alzheimer's Association to reassess the original NIA criteria for the postmortem diagnosis of Alzheimer's disease published in 1985. The consensus recommendations for improving the neuropathological criteria for the postmortem diagnosis of Alzheimer's disease are reported here, and the "position papers" by members of the Working Group that accompany this report elaborate on the research findings and concepts upon which these recommendations were based. Further, commentaries by other experts in the field also are included here to provide additional perspectives on these recommendations. Finally, it is anticipated that future meetings of the Working Group will reassess these recommendations and the implementation of postmortem diagnostic criteria for Alzheimer's disease.

Developing a professional identity: student nurses in the workplace.

This analysis of the academic and student discourse about learning in the practicum in one Australian pre-registration Bachelor of Nursing course is part of a larger study examining the professional identity of undergraduate students in three professional groups: nursing, teaching and engineering. The focus group discussion of six student nurses reveals that the theories learned in the classroom are only partially useful preparation for the relationships required to work as a nurse in a people-laden workplace; students struggle to create meaning about practices that are not consistent with classroom theory; and students require support as they develop an identity of a nurse through the embodiment of practice work. The findings from this group support the view that the traditional approach to learning, as expressed in the documentation for the final practicum experience, where knowledge is certain, context-free, and disciplinary or subject focused, is insufficient to assist student readiness for the world of work. Recommendations emerging from this analysis are related to the university and provides some evidence for others teaching in nursing programs to reconsider their practices.

Teaching Students How to Study: A Workshop on Information Processing and Self-Testing Helps Students Learn

Stanger-Hall, Kathrin F.; Shockley, Floyd W.; Wilson, Rachel E.

2011-01-01

We implemented a “how to study” workshop for small groups of students (6–12) for N = 93 consenting students, randomly assigned from a large introductory biology class. The goal of this workshop was to teach students self-regulating techniques with visualization-based exercises as a foundation for learning and critical thinking in two areas: information processing and self-testing. During the workshop, students worked individually or in groups and received immediate feedback on their progress. Here, we describe two individual workshop exercises, report their immediate results, describe students’ reactions (based on the workshop instructors’ experience and student feedback), and report student performance on workshop-related questions on the final exam. Students rated the workshop activities highly and performed significantly better on workshop-related final exam questions than the control groups. This was the case for both lower- and higher-order thinking questions. Student achievement (i.e., grade point average) was significantly correlated with overall final exam performance but not with workshop outcomes. This long-term (10 wk) retention of a self-testing effect across question levels and student achievement is a promising endorsement for future large-scale implementation and further evaluation of this “how to study” workshop as a study support for introductory biology (and other science) students.

Eight techniques used by the author in teaching an introductory applied behavior analysis course are described: (a) a detailed study guide, (b) frequent tests, (c) composition of practice test questions, (d) in-class study groups, (e) fluency building with a computerized flash-card program, (f) bonus marks for participation during question-and-answer sessions, (g) student presentations that summarize and analyze recently published research, and (h) in-class behavior analysis of comic strips. Together, these techniques require an extensive amount of work by students. Nevertheless, students overwhelmingly prefer this approach to the traditional lecture-midterm-final format, and most earn an A as their final course grade. PMID:22478226

The present study investigated the accuracy of root canal preparation with regard to the integrity of the apical constriction (AC) using two different working length determination approaches: (1) the electronic method of working length determination (EWLD), and (2) the radiologic "gold standard" method (GS). Simulation models were constructed by arranging extracted human teeth by means of silicon bolstered gingiva masks, along with a conductive medium (alginate). Electronic working length determination (group 1; EWLD) and radiologic plus initial electronic working length determination for posterior comparability (group 2; GS) preceded manual root canal preparation of teeth in both groups. Master cones were inserted according to working lengths obtained from the group specific method. Subsequently, root apices (n=36) were longitudinally sectioned using a diamond-coated bur. The distance between the achieved apical endpoint of the endodontic preparation and the apical constriction (AC) was measured using digital photography. Then, distances between radiologically identified apical endpoints and AC (GS-AC) were compared with the corresponding distances EWLD-AC. Moreover, the postoperative status of the AC was examined with regard to both preparation approaches. Differences between distances GS-AC and EWLD-AC were not statistically significant (p >0.401) (Mann-Whitney-U). Among EWLD samples, 83% of the master cones exhibiting tugback at final insertion terminated close to the apical constriction (±0.5 mm), and no impairment of the minor diameter's integrity was observed. The sole use of EWLD allowed for a high accuracy of measurements and granted precise preparation of the apical regions. Copyright © 2017 Elsevier Ltd. All rights reserved.

Using an integrated approach to the assessment of the psychosocial work environment: the case of a major hospital in northern Italy.

In 2010, Italian regulatory guidelines have been issued consisting of a stepwise procedure for the assessment and management of work-related stress. However, research that empirically examines whether this procedure proves effective in accurately identifying critical psychosocial factors and informing risk management is scarce. To examine the differential sensitivity of two approaches to risk assessment, the first based on objective instruments only, the second consisting of an integrated approach combining different methods and theoretical perspectives. We examined a sample of 306 healthcare employees in a large-size hospital in northern Italy, using a series of tools, both quantitative (an observational checklist and the HSE-IT and MOHQ questionnaires) and qualitative (Focus Groups). Through instrument-specific reference values, we then compared risk profiles between different homogeneous groups within the institution. The psychosocial work environment resulted to be far more positive when adopting the first compared to the second approach to risk assessment. The latter approach was also more sensitive in detecting between-groups differences in risk profiles. Furthermore, the Focus Groups returned a more context-specific picture of the psychosocial work environment. Finally, going beyond the emphasis on negative working conditions inherent in the other quantitative instruments, the MOHQ allowed for also identifying health-promoting factors in need for improvement. Although more research is needed to confirm our findings, the present study suggests that using an integrated approach to assess the psychosocial work environment may be the most effective way to accurately identify risk factors and support the management process.

Final technical report for Conjugated ionomers for photovoltaic applications, electric field driven charge separation in organic photovoltaics. The central goal of the work we completed was been to understand the photochemical and photovoltaic properties of ionically functionalized conjugated polymers (conjugated ionomers or polyelectrolytes) and energy conversion systems based on them. We primarily studied two classes of conjugated polymer interfaces that we developed based either upon undoped conjugated polymers with an asymmetry in ionic composition (the ionic junction) or doped conjugated polymers with an asymmetry in doping type (the p-n junction). The materials used for these studies have primarily been themore » polyacetylene ionomers. We completed a detailed study of p-n junctions with systematically varying dopant density, photochemical creation of doped junctions, and experimental and theoretical work on charge transport and injection in polyacetylene ionomers. We have also completed related work on the use of conjugated ionomers as interlayers that improve the efficiency or organic photovoltaic systems and studied several important aspects of the chemistry of ionically functionalized semiconductors, including mechanisms of so-called "anion-doping", the formation of charge transfer complexes with oxygen, and the synthesis of new polyfluorene polyelectrolytes. We also worked worked with the Haley group at the University of Oregon on new indenofluorene-based organic acceptors.« less

The objective of this study was to undertake a research priority setting exercise with the aim of maximizing efficiency and impact in research activity undertaken by nurses at one children's tertiary healthcare institution by ensuring the clinical staff directly shaped a coherent, transparent and consensus driven nurse-led research agenda. In Round 1, the research topics of 147 nurses were elicited using a modified nominal group technique as the consensus method. The number of participants in the 24 separate discussions ranged from 3 to 21, generating lists of between 6 and 23 topics. In Round 2, nurses from the clinical areas ranked topics of importance resulting in a set of four to five priorities. In Round 3, the divisional heads of nursing consulted with staff in all of their clinical areas to each finalize their five divisional priorities. The Nursing Research Working Group discussed and refined the divisions' priorities and voted on the final list to agree the top five research priorities for the organization. A total of 269 research topics were initially generated. Following three rounds of ranking and prioritizing, five priorities were agreed at Divisional level, and from these, the five top organizational priorities were selected. These were (i) understanding and improving all aspects of the patient journey through the hospital system; (ii) play; (iii) staff wellbeing, patient care and productivity; (iv) team work - linking to a more efficient service; and (v) supporting parents/parent pathway. Divisional priorities have been disseminated widely to clinical teams to inform a patient-specific nurse-led research agenda. Organizational priorities agreed upon have been disseminated through management structures and processes to ensure engagement at all levels. A subgroup of the Nursing Research Working Group has been delegated to take this work forward so that the agreed priorities continue to contribute towards shaping nurse-led research activity, thereby going some way to inform and embed an evidence-based culture of inquiry. © 2016 John Wiley & Sons Ltd.

Peer Grading in Astronomy Massive Open Online Course

Formanek, Martin; Wenger, Matthew; Impey, Christopher; Buxner, Sanlyn

In this work we thoroughly investigate the peer grading process as it happened in the University of Arizona session based MOOC ``Astronomy: Exploring Time and Space'' offered during Spring 2015 through Coursera. Overall, 25400 learners from over 100 countries registered for this course. Of those, 14900 accessed at least one part of the course and 1332 users engaged in the peer grading. First of all we provide description of the peer graded assignments and we identify trends in behavior of people who participated in these exercises. E.g. time they spent on grading, number of assignments graded and patterns arising from comparing all three assignments. Furthermore, for the second assignment, we graded random sample of 300 essays by a group of trained undergraduate students and a group consisting of one of the course instructors together with graduate TAs and we compared results with grades from the peer grading. Specifically we look on Intraclass Correlation Coefficients for all three groups of graders to determine reliability of each group and correlations between final grades. Finally we assess factors influencing reliability of the peer graders participating in the MOOC based on the difference from our grades. This research was supported by Howard Hughes Medical Institute Grant No. 415580.

Developing physician pay arrangements: the cash and care equation.

PubMed

Levitch, J H

1998-11-01

Developing physician compensation packages that help a healthcare organization meet its business objectives while satisfying physician pay expectations requires new ways of linking pay to physician performance. Such compensation arrangements specifically should include pay tied to defined performance standards, compensation linked to group performance, performance incentives based on realistic, achievable goals, work performance measured by common criteria, and similar pay ensured for similar work. Final pay arrangements also should include items that are sometimes overlooked, such as fully delineated job responsibilities, performance measures aligned correctly with performance areas, and the value of benefits considered in the cash compensation levels.

Decent work is positioned as the centerpiece of the recently developed Psychology of Working Theory (PWT; Duffy, Blustein, Diemer, & Autin, 2016). However, to date, no instrument exists which assesses all 5 components of decent work from a psychological perspective. In the current study, we developed the Decent Work Scale (DWS) and demonstrated several aspects of validity with 2 samples of working adults. In Study 1 (N = 275), a large pool of items were developed and exploratory factor analysis was conducted resulting in a final 15-item scale with 5 factors/subscales corresponding to the 5 components of decent work: (a) physically and interpersonally safe working conditions, (b) access to health care, (c) adequate compensation, (d) hours that allow for free time and rest, and (e) organizational values that complement family and social values. In Study 2 (N = 589), confirmatory factor analysis demonstrated that a 5-factor, bifactor model offered the strongest and most parsimonious fit to the data. Configural, metric, and scalar invariance models were tested demonstrating that the structure of the instrument did not differ across gender, income, social class, and majority/minority racial/ethnic groups. Finally, the overall scale score and 5 subscale scores correlated in the expected directions with similar constructs supporting convergent and discriminant evidence of validity, and subscale scores evidenced predictive validity in the prediction of job satisfaction, work meaning, and withdrawal intentions. The development of this scale provides a useful tool for researchers and practitioners seeking to assess the attainment of decent work among employed adults.

Computer technology applications in industrial and organizational psychology.

PubMed

Crespin, Timothy R; Austin, James T

2002-08-01

This article reviews computer applications developed and utilized by industrial-organizational (I-O) psychologists, both in practice and in research. A primary emphasis is on applications developed for Internet usage, because this "network of networks" changes the way I-O psychologists work. The review focuses on traditional and emerging topics in I-O psychology. The first topic involves information technology applications in measurement, defined broadly across levels of analysis (persons, groups, organizations) and domains (abilities, personality, attitudes). Discussion then focuses on individual learning at work, both in formal training and in coping with continual automation of work. A section on job analysis follows, illustrating the role of computers and the Internet in studying jobs. Shifting focus to the group level of analysis, we briefly review how information technology is being used to understand and support cooperative work. Finally, special emphasis is given to the emerging "third discipline" in I-O psychology research-computational modeling of behavioral events in organizations. Throughout this review, themes of innovation and dissemination underlie a continuum between research and practice. The review concludes by setting a framework for I-O psychology in a computerized and networked world.

Working memory and reward association learning impairments in obesity.

2014-12-01

Obesity has been associated with impaired executive functions including working memory. Less explored is the influence of obesity on learning and memory. In the current study we assessed stimulus reward association learning, explicit learning and memory and working memory in healthy weight, overweight and obese individuals. Explicit learning and memory did not differ as a function of group. In contrast, working memory was significantly and similarly impaired in both overweight and obese individuals compared to the healthy weight group. In the first reward association learning task the obese, but not healthy weight or overweight participants consistently formed paradoxical preferences for a pattern associated with a negative outcome (fewer food rewards). To determine if the deficit was specific to food reward a second experiment was conducted using money. Consistent with Experiment 1, obese individuals selected the pattern associated with a negative outcome (fewer monetary rewards) more frequently than healthy weight individuals and thus failed to develop a significant preference for the most rewarded patterns as was observed in the healthy weight group. Finally, on a probabilistic learning task, obese compared to healthy weight individuals showed deficits in negative, but not positive outcome learning. Taken together, our results demonstrate deficits in working memory and stimulus reward learning in obesity and suggest that obese individuals are impaired in learning to avoid negative outcomes.

Dogs have become the focus of cognitive studies looking at both their physical and social problem-solving abilities (Bensky et al. in Adv Stud Behav, 45:209-387, 2013), but very little is known about the environmental and inherited factors that may affect these abilities. In the current study, we presented a manipulation task (a puzzle box) and a spatial task (the detour) to 128 dogs belonging to four different breed groups: Herding, Mastiff-like, Working and Retrievers (von Holdt et al. in Nature 464:898-902, 2010). Within each group, we tested highly trained and non-trained dogs. Results showed that trained dogs were faster at obtaining the reward in the detour task. In the manipulation task, trained dogs approached the apparatus sooner in the first familiarization trial, but no effect of breed emerged on this variable. Furthermore, regardless of breed, dogs in the trained group spent proportionally more time interacting with the apparatus and were more likely to succeed in the test trial than dogs in the non-trained group, whereas regardless of training, dogs in the working breed group were more likely to succeed than dogs in the retriever and herding breed groups (but not the mastiff-like group). Finally, trained dogs were less likely to look at a person than non-trained dogs during testing, but dogs in the herding group more likely to do so than dogs in the retriever and working but not the mastiff-like breed groups. Overall, results reveal a strong influence of training experience but less consistent differences between breed groups on different components thought to affect problem solving.

There is no commonly accepted standardized terminology for oral diagnoses. The purpose of this article is to report the development of a standardized dental diagnostic terminology by a work group of dental faculty members. The work group developed guiding principles for decision making and adhered to principles of terminology development. The members used an iterative process to develop a terminology incorporating concepts represented in the Toronto/University of California, San Francisco/Creighton University and International Classification of Diseases (ICD)-9/10 codes and periodontal and endodontic diagnoses. Domain experts were consulted to develop a final list of diagnostic terms. A structure was developed, consisting of thirteen categories, seventy-eight subcategories, and 1,158 diagnostic terms, hierarchically organized and mappable to other terminologies and ontologies. Use of this standardized diagnostic terminology will reinforce the diagnosis-treatment link and will facilitate clinical research, quality assurance, and patient communication. Future work will focus on implementation and approaches to enhance the validity and reliability of diagnostic term utilization. PMID:21205730

Personality Trait Development and Social Investment in Work

2012-01-01

A longitudinal study of employed individuals was used to test the relationship between social investment at work—the act of cognitively and emotionally committing to one’s job—and longitudinal and cross-sectional personality trait development. Participants provided ratings of personality traits and social investment at work at two time-points, separated by approximately three years. Data were analyzed using latent change models. Cross-sectional results showed that extraversion, agreeableness, conscientiousness and emotional stability were related to social investment at work. Additionally, a positive association was found between longitudinal change in social investment in work and change in personality traits—especially conscientiousness. Finally, the correlated changes in social investment and personality traits were invariant across age groups, suggesting that personality traits remain malleable across the lifespan. PMID:22822278

2013-01-01

Background Radar transmitters emit high-power radiofrequency radiation by creation of a high-voltage and high-frequency alternating electrical current. Methods: Health effects of occupational exposure to military radar were investigated. Visual reaction time was recorded with a simple blind computer-assisted-visual reaction time test. To assess the short-term memory, modified Wechsler Memory Scale test was performed. Results: The mean +/- SD reaction time in radar works (N=100) and the control group (N=57) were 238.58 +/− 23.47 milliseconds and 291.86 +/− 28.26 milliseconds (P<0.0001), respectively. The scores of forward digit span in radar works and the control group were 3.56 +/− 0.77 and 4.29 +/− 1.06 (P<0.0001), while the scores of backward digit span in radar works and the control group were 2.70 +/− 0.69 and 3.62 +/− 0.95 (P<0.0001). The scores of word recognition in radar works and the control group were 3.37 +/− 1.13 and 5.86 +/− 1.11 (P<0.0001). Finally, the scores of paired words in radar works and the control group were 13.56 +/− 1.78 and 15.21 +/− 2.20 (P<0.0001). It can be concluded that occupational exposures to radar radiations decreases reaction time, which may lead to a better response to different hazards. Conclusion: To the best of our knowledge, this is the first study to show that occupational exposure to radar microwave radiation leads to decreased reaction time and the lower performance of short-term memory. Altogether, these results indicate that occupational exposure to radar microwave radiations may be linked to some non-detrimental and detrimental health effects. PMID:23785684

Disturbed sleep is one of the most common complaints following traumatic brain injury (TBI) and worsens morbidity and long-term sequelae. Further, sleep and TBI share neurophysiologic underpinnings with direct relevance to recovery from TBI. As such, disturbed sleep and clinical sleep disorders represent modifiable treatment targets to improve outcomes in TBI. This paper presents key findings from a national working group on sleep and TBI, with a specific focus on the testing and development of sleep-related therapeutic interventions for mild TBI (mTBI). First, mTBI and sleep physiology are briefly reviewed. Next, essential empirical and clinical questions and knowledge gaps are addressed. Finally, actionable recommendations are offered to guide active and efficient collaboration between academic, industry, and governmental stakeholders.

The National Cancer Institute (NCI) Symptom Management and Health-Related Quality of Life Steering Committee convened four working groups to recommend core sets of patient-reported outcomes to be routinely incorporated in clinical trials. The Prostate Cancer Working Group included physicians, researchers, and a patient advocate. The group's process included 1) a systematic literature review to determine the prevalence and severity of symptoms, 2) a multistakeholder meeting sponsored by the NCI to review the evidence and build consensus, and 3) a postmeeting expert panel synthesis of findings to finalize recommendations. Five domains were recommended for localized prostate cancer: urinary incontinence, urinary obstruction and irritation, bowel-related symptoms, sexual dysfunction, and hormonal symptoms. Four domains were recommended for advanced prostate cancer: pain, fatigue, mental well-being, and physical well-being. Additional domains for consideration include decisional regret, satisfaction with care, and anxiety related to prostate cancer. These recommendations have been endorsed by the NCI for implementation. © The Author 2014. Published by Oxford University Press. All rights reserved.

Approximately 25% of working-aged Americans with disabilities work full or part time, yet still face discrimination despite the passing of the American's with Disabilities Act (ADA) over 20 years ago. To determine if the proportion of allegations of ADA Title I workplace discrimination with merit closed at any year between 1993 and 2008 differs among Whites, African Americans, Hispanics, and Asians; to determine if there was a change over time from 1993 to 2008 in merit closure rate within each race/ethnicity group; and to determine whether changes over time between 1993 and 2008 in the merit closure rate differ among the race/ethnicity groups. Logistic regression was used for this cross-sectional panel study to model the merit closure rate for each ethnic group from 1993 to 2008 using 318,587 charging parties from the EEOC database. All ethnic groups exhibited significant changes over time in the merit closure rate. There were significant differences in the closure rates among the race/ethnicity groups specifically at closure years 1995-2000, 2002, 2003, and 2006. Finally, there was evidence that the trends in merit closure rates over time differed significantly among the race/ethnicity groups. There was significant evidence that the proportion of claims closed with merit was significantly different among the racial/ethnicity groups.

The Outcome Measures in Rheumatology (OMERACT) Shoulder Core Outcome Set Special Interest Group (SIG) was established to develop a core outcome set (COS) for clinical trials of shoulder disorders. In preparation for OMERACT 2016, we systematically examined all outcome domains and measurement instruments reported in 409 randomized trials of interventions for shoulder disorders published between 1954 and 2015. Informed by these data, we conducted an international Delphi consensus study including shoulder trial experts, clinicians, and patients to identify key domains that should be included in a shoulder disorder COS. Findings were discussed at a stakeholder premeeting of OMERACT. At OMERACT 2016, we sought consensus on a preliminary core domain set and input into next steps. There were 13 and 15 participants at the premeeting and the OMERACT 2016 SIG meeting, respectively (9 attended both meetings). Consensus was reached on a preliminary core domain set consisting of an inner core of 4 domains: pain, physical function/activity, global perceived effect, and adverse events including death. A middle core consisted of 3 domains: emotional well-being, sleep, and participation (recreation and work). An outer core of research required to inform the final COS was also formulated. Our next steps are to (1) analyze whether participation (recreation and work) should be in the inner core, (2) conduct a third Delphi round to finalize definitions and wording of domains and reach final endorsement for the domains, and (3) determine which instruments fulfill the OMERACT criteria for measuring each domain.

The field of genomics is rapidly impacting medical care across specialties. To help guide test utilization and interpretation, pathologists must be knowledgeable about genomic techniques and their clinical utility. The technology allowing timely generation of genomic data is relatively new to patient care and the clinical laboratory, and therefore, many currently practicing pathologists have been trained without any molecular or genomics exposure. Furthermore, the exposure that current and recent trainees receive in this field remains inconsistent. To assess pathologists' learning needs in genomics and to develop a curriculum to address these educational needs. A working group formed by the College of American Pathologists developed an initial list of genomics competencies (knowledge and skills statements) that a practicing pathologist needs to be successful. Experts in genomics were then surveyed to rate the importance of each competency. These data were used to create a final list of prioritized competencies. A subset of the working group defined subtopics and tasks for each competency. Appropriate delivery methods for the educational material were also proposed. A final list of 32 genomics competency statements was developed. A prioritized curriculum was created with designated subtopics and tasks associated with each competency. We present a genomics curriculum designed as a first step toward providing practicing pathologists with the competencies needed to practice successfully.

Is it better to be average? High and low performance as predictors of employee victimization.

PubMed

Jensen, Jaclyn M; Patel, Pankaj C; Raver, Jana L

2014-03-01

Given increased interest in whether targets' behaviors at work are related to their victimization, we investigated employees' job performance level as a precipitating factor for being victimized by peers in one's work group. Drawing on rational choice theory and the victim precipitation model, we argue that perpetrators take into consideration the risks of aggressing against particular targets, such that high performers tend to experience covert forms of victimization from peers, whereas low performers tend to experience overt forms of victimization. We further contend that the motivation to punish performance deviants will be higher when performance differentials are salient, such that the effects of job performance on covert and overt victimization will be exacerbated by group performance polarization, yet mitigated when the target has high equity sensitivity (benevolence). Finally, we investigate whether victimization is associated with future performance impairments. Results from data collected at 3 time points from 576 individuals in 62 work groups largely support the proposed model. The findings suggest that job performance is a precipitating factor to covert victimization for high performers and overt victimization for low performers in the workplace with implications for subsequent performance.

Knowledge on the role of Helicobacter pylori (HP) infection is continually evolving, and treatment is becoming more challenging due to increasing bacterial resistance. Since the management of HP infection is changing, an update of the national Italian guidelines delivered in 2007 was needed. In the III Working Group Consensus Report 2015, a panel of 17 experts from several Italian regions reviewed current evidence on different topics relating to HP infection. Four working groups examined the following topics: (1) "open questions" on HP diagnosis and treatment (focusing on dyspepsia, gastro-oesophageal reflux disease, non-steroidal anti-inflammatory drugs or aspirin use and extra-gastric diseases); (2) non-invasive and invasive diagnostic tests; (3) treatment of HP infection; (4) role of HP in the prevention of gastric cancer. Statements and recommendations were discussed and a consensus reached in a final plenary session held in February 2015 in Bologna. Recommendations are based on the best current evidence to help physicians manage HP infection in Italy. The guidelines have been endorsed by the Italian Society of Gastroenterology and the Italian Society of Digestive Endoscopy. Copyright © 2015 Editrice Gastroenterologica Italiana S.r.l.

Cardiovascular control during whole body exercise

2016-01-01

It has been considered whether during whole body exercise the increase in cardiac output is large enough to support skeletal muscle blood flow. This review addresses four lines of evidence for a flow limitation to skeletal muscles during whole body exercise. First, even though during exercise the blood flow achieved by the arms is lower than that achieved by the legs (∼160 vs. ∼385 ml·min−1·100 g−1), the muscle mass that can be perfused with such flow is limited by the capacity to increase cardiac output (42 l/min, highest recorded value). Secondly, activation of the exercise pressor reflex during fatiguing work with one muscle group limits flow to other muscle groups. Another line of evidence comes from evaluation of regional blood flow during exercise where there is a discrepancy between flow to a muscle group when it is working exclusively and when it works together with other muscles. Finally, regulation of peripheral resistance by sympathetic vasoconstriction in active muscles by the arterial baroreflex is critical for blood pressure regulation during exercise. Together, these findings indicate that during whole body exercise muscle blood flow is subordinate to the control of blood pressure. PMID:27311439

On February 10, 2010, the official proposals for the personality disorders section of the fifth edition of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM-5) were posted (see www.dsm5.org ). The posting by the DSM-5 Personality and Personality Disorders Work Group has been helpful in informing the field of the possible changes that may occur with DSM-5. Their presence allows for and encourages persons to provide their suggestions and concerns. The extent of the proposals is considerable. As expressed on the website, "the work group recommends a major reconceptualization of personality psychopathology" (Skodol, 2010, "Reformulation of personality disorders in DSM-5," para. 1). The proposals have generated some controversy. The Journal of Personality Disorders has always sought to be a participant in the crucial debates in our field. The purpose of this special issue is to provide members of the Work Group the opportunity to further articulate the rationale for the proposals, and to provide others an opportunity to articulate their concerns. Copies of this special issue were distributed to interested persons when the complete set of final papers were received (October of 2010).

Sporting activity is becoming a common practice in patients with diabetes mellitus (DM). This situation requires both a preliminary medical assessment and a wide range of changes in treatment which have scarcely been addressed in medical literature. To prepare a clinical guideline on the medical approach to patients with diabetes who practice sport regularly. An expert panel from the Diabetes Mellitus Working Group of the Spanish Society of Endocrinology and Nutrition (SEEN) reviewed the most relevant literature in each of the sections. Based both on this review and on data from the experience of a number of athletes with DM, a number of recommendations were agreed within each section. Finally, the Working Group and representatives of the SEEN jointly discussed all these recommendations. The guideline provides recommendations ranging from medical assessment before patients with DM start to practice sport to actions during and after physical activity. Recommendations are also given on aspects such as the impact of sport on blood glucose control, training schemes, or special risk situations. Copyright © 2015 SEEN.

This project is responsive to the premise that the successful analysis of equipment reliability and system adequacy in bulk transmission system planning and system operations requires data on equipment failure rates, maintenance outage rates and repair times. The objective of the project is to develop a system of consistent definitions, formats and procedures which can be used in the collection of such data in a well designed outage data bank. The project consisted of four interrelated phases, beginning with a review of related work and problem definition and ending with a discussion of data base organization and management. The reviewmore » of related work quickly pointed out that two schools of thought exist on data collection. One group contends that data should be collected on bulk transmission system physical equipments, such as transformers, circuit breakers, etc., and the other group supports data collection on functional transmission lines, including the terminal equipment, which have been defined as transmission units in this report. A compromise between these two approaches was imperative for successful completion of the work. The second phase investigated the data needed for reliability evaluation. The applications of the data bank were enumerated leading to a list of basic data needed when recording an incident. Phase 3 concentrated on developing procedures for data collection using forms to collect data both on outages and on the equipment design. Finally, the aspects of data base organization and management were explored and general recommendations made appropriate to this specific application. The project did not succeed in completely defining the procedures, particularly for multiple outages, but the ground work has been laid for a pilot data collection effort to refine the procedures before wide scale implementation by the utility industry.« less

The aim of this study was to assess the use of local interprofessional or audit groups as a tool of quality enhancement. Fifty-six doctors, physiotherapists and nurses attended nine local interprofessional groups. The aim was to improve the quality of each professional's practice and to improve communication between the professions. The groups had a total of 62 meetings with each professional attending on average 5.7 meetings. All groups initiated quality enhancement projects. Initially the groups were very active and showed great initiative, but there were few final results. However, many groups reported improved communication and cooperation between the participating professionals. The experience from this project may be summarised as follows: The professionals within one and the same group should have more or less the same background and specialty. We recommend caution with organising interprofessional groups unless their participants work in the same practice. Interprofessional groups should spend adequate time for the members to get to know each other, and they should be guided by an experienced leader.

2008-04-01

The objective of this study was to determine what makes men and women with musculoskeletal complaints decide to call in sick for work. Qualitative, face-to-face interviews were used with employees (16 men and 14 women) who had called in sick due to a musculoskeletal complaint and who expected to be absent from work for at least 2 weeks on sick leave. The participants fell into the following two main groups: those who were off sick because of a diagnosed medical condition, such as a fracture, and those who were off sick because of an unidentifiable complaint, such as low-back pain. Employees in the former group called in sick because they were in the hospital or because they reckoned that their condition was too serious to warrant a continuation of work. Employees in the latter group felt hesitant and insecure and found it hard to judge whether absenteeism was justified. They decided either to "play it safe" and stay off work to prevent the complaints from worsening or to seek advice from medical professionals. Their advice did not include explicit instructions to stay at home, but were usually interpreted as such. Finally, women, but not men, were likely to call in sick if they felt that their home situation was being negatively affected by attempts to keep working while suffering physical complaints. The decision to call in sick is not taken lightly. Employees with nonspecific disorders base their decision on several factors, including advice from medical professionals. A factor found only among women was work-home interference.

The objective of the North American Spine Society (NASS) Evidence-Based Clinical Guideline on antithrombotic therapies in spine surgery was to provide evidence-based recommendations to address key clinical questions surrounding the use of antithrombotic therapies in spine surgery. The guideline is intended to address these questions based on the highest quality clinical literature available on this subject as of February 2008. The goal of the guideline recommendations was to assist in delivering optimum, efficacious treatment with the goal of preventing thromboembolic events. To provide an evidence-based, educational tool to assist spine surgeons in minimizing the risk of deep venous thrombosis (DVT) and pulmonary embolism (PE). Systematic review and evidence-based clinical guideline. This report is from the Antithrombotic Therapies Work Group of the NASS Evidence-Based Guideline Development Committee. The work group was composed of multidisciplinary spine care specialists, all of whom were trained in the principles of evidence-based analysis. Each member of the group was involved in formatting a series of clinical questions to be addressed by the group. The final questions agreed on by the group are the subject of this report. A literature search addressing each question and using a specific search protocol was performed on English language references found in MEDLINE, EMBASE (Drugs and Pharmacology), and four additional, evidence-based databases. The relevant literature was then independently rated by at least three reviewers using the NASS-adopted standardized levels of evidence. An evidentiary table was created for each of the questions. Final grades of recommendation for the answers to each clinical question were arrived at via Web casts among members of the work group using standardized grades of recommendation. When Level I to IV evidence was insufficient to support a recommendation to answer a specific clinical question, expert consensus was arrived at by the work group through the modified nominal group technique and is clearly identified as such in the guideline. Fourteen clinical questions were formulated, addressing issues of incidence of DVT and PE in spine surgery and recommendations regarding utilization of mechanical prophylaxis and chemoprophylaxis in spine surgery. The answers to these 14 clinical questions are summarized in this article. The respective recommendations were graded by the strength of the supporting literature that was stratified by levels of evidence. A clinical guideline addressing the use of antithrombotic therapies in spine surgery has been created using the techniques of evidence-based medicine and using the best available evidence as a tool to assist spine surgeons in minimizing the risk of DVT and PE. The entire guideline document, including the evidentiary tables, suggestions for future research, and all references, is available electronically at the NASS Web site (www.spine.org) and will remain updated on a timely schedule.

Obtaining a correct working length is necessary for successful root canal treatment. The aim of this study was to compare conventional and digital radiography in measuring root canal working length. In this in vitro study 20 mesio buccal canal from maxillary first molars with moderate and severe curvature and 20 canal form anterior teeth with mild curvature were chosen and their working length were measured with number 15 k file (Maillefer, DENTSPLY, Germany). Then for each canal five radiographies were taken, three conventional radiographies using three methods of processing: Manual, automatic, and monobath solution; in addition to two other digital radiographies using CCD and PSP receptors. Two independent observers measured working length in each technique. Finally, the mean of working length in each group was compared with real working length using a paired T-test. Also a one-way ANOVA test was used for comparing the two groups. The level of statistical significance was P < 0.05. The results have shown that there was a high interobserver agreement on the measurements of the working length in conventional and digital radiography (P ≤ 0.001). Also there was no significant difference between conventional and digital radiography in measuring working length (P > 0.05). Therefore it was concluded that the accuracy of digital radiography is comparable with conventional radiography in measuring working length, so considering the advantages of the digital radiography, it can be used for working length determination.

Due to a new legislation, the assessment of work stress has become compulsory in Italy for all the enterprise. Work stress is become a leading health problem in work settings all over Europe. The two major approaches, the expert-based direct observations and the measurements of the perceived job strain, are briefly introduced emphasizing on strengthens and weaknesses. Among the methods to assess perceived job stress, the Karasek's Job Content Questionnaire has been extensively used in Italy, and the available results support its use because reliable and able to pick up major constrictiveness at work. In addition, because it is now possible to have reference levels, comparisons are possible for either public or private enterprises. Acknowledging the complexity of carrying out reliable assessment of work stress, a multiphase approach is emphasised: first an analysis or current data can be used to estimate the levels of turnover, down-sizing, outsourcing, extra hours, shift work, sickness absenteeism, changes of job titles, work accidents and work-related diseases. At a second step, on groups of workers selected because recognised at risk at the first phase and on control groups, the JCQ can be used to assess workers stress perception. Finally, when constrain conditions emerge,further investigations are required, including: intervention of experts in work organisation analysis, clinical psychological examinations of selected workers, to separate between work-related and personal psychological problems and health consequences.

The aim was to identify differences in self-reported symptoms among working (W) and non-working (NW) women, and to determine the most important biopsychosocial variables in differentiating one group from the other. A questionnaire was mailed to 524 members of a local chapter of the Swedish Rheumatology Association. A total of 362 persons responded (69%); 96% of which were women. Women older than 64 years and all men were excluded. The final study group consisted of 95 W, and 227 NW women. The questionnaire included data on demographics, employment, support, exercise, daily activities and symptoms. Data were analysed using univariate statistics and a partial least squares discriminant analysis (PLS-DA). The results showed that 41% of the W and 42% of the NW women were/had been employed in service,care or business. The NW women reported a significantly higher severity of symptoms compared with the W women. The most important variable when differentiating the W from the NW women was social support from colleagues and employers. To change prevailing attitudes and values towards persons with a work disability, a process of active intervention involving staff is needed. Educating employers as to how a disability may influence a work situation, and the importance of social support, can be improved.

The American Society for Colposcopy and Cervical Pathology (ASCCP) Colposcopy Standards recommendations address the role of and approach to colposcopy and biopsy for cervical cancer prevention in the United States. The recommendations were developed by an expert working group appointed by ASCCP's Board of Directors. Working group 3 defined colposcopy procedure guidelines for minimum and comprehensive colposcopy practice and evaluated the use of colposcopy adjuncts. The working group performed a systematic literature review to identify best practices in colposcopy methodology and to evaluate the use of available colposcopy adjuncts. The literature provided little evidence to support specific elements of the procedure. The working group, therefore, implemented a national survey of current and recent ASCCP members to evaluate common elements of the colposcopy examination. The findings of this survey were modified by expert consensus from the ASCCP Colposcopy Standards Committee members to create guidelines for performing colposcopy. The draft recommendations were posted online for public comment and presented at an open session of the International Federation for Cervical Pathology and Colposcopy 2017 World Congress for further comment. All comments were considered in the development of final recommendations. Minimum and comprehensive colposcopy practice guidelines were developed. These guidelines represent recommended practice in all parts of the examination including the following: precolposcopy evaluation, performing the procedure, documentation of findings, biopsy practice, and postprocedure follow-up. These guidelines are intended to serve as a guide to standardize colposcopy across the United States.

Video game training with older adults potentially enhances aspects of cognition that decline with aging and could therefore offer a promising training approach. Although, previous published studies suggest that training can produce transfer, many of them have certain shortcomings. This randomized controlled trial (RCT; Clinicaltrials.gov ID: NCT02796508) tried to overcome some of these limitations by incorporating an active control group and the assessment of motivation and expectations. Seventy-five older volunteers were randomly assigned to the experimental group trained for 16 sessions with non-action video games from Lumosity , a commercial platform (http://www.lumosity.com/) or to an active control group trained for the same number of sessions with simulation strategy games. The final sample included 55 older adults (30 in the experimental group and 25 in the active control group). Participants were tested individually before and after training to assess working memory (WM) and selective attention and also reported their perceived improvement, motivation and engagement. The results showed improved performance across the training sessions. The main results were: (1) the experimental group did not show greater improvements in measures of selective attention and working memory than the active control group (the opposite occurred in the oddball task); (2) a marginal training effect was observed for the N -back task, but not for the Stroop task while both groups improved in the Corsi Blocks task. Based on these results, one can conclude that training with non-action games provide modest benefits for untrained tasks. The effect is not specific for that kind of training as a similar effect was observed for strategy video games. Groups did not differ in motivation, engagement or expectations.

Interprofessional education (IPE) is a process through which students are provided with learning opportunities with other professions aiming to improve client care. The need to include effective IPE in preregistration programmes for health professionals is increasingly being recognised. The overall aim of the present study was to explore the perceptions and experiences of final-year dietetics students of IPE delivered through interactive online learning groups. A questionnaire was developed to evaluate the students' satisfaction with the IPE modules, including importance to their clinical placements, and their understanding of the roles of other professions. Six dietetics students took part in a focus group that addressed the impact of participating in the IPE modules. The focus group discussion was recorded, transcribed and subjected to content analysis. Twenty students completed the questionnaire (77% of the cohort). Satisfaction with the IPE modules increased as the programme progressed, with 65%, 90% and 95% of the respondents, respectively, being satisfied with the content, assessment and access of the final module. Participating in the programme enhanced the students' opinions on the value of the roles of other professionals (80%) and enhanced their awareness of interprofessional issues (75%). Four key areas of interest emerged from the focus group analysis: key impressions; understanding the role of the dietitian and other professionals; the advantages and disadvantages of online delivery; and interprofessional working in the work environment. The most important outcome of participating in IPE was that students' knowledge of other professions was enhanced, which had a positive impact on placements. An effective information technology infrastructure and appropriate scenarios are key requirements for the online delivery of IPE. © 2011 The Authors.

Animal models of alcohol-seeking are useful for understanding alcohol addiction and for treatment development, but throughput in these models is limited by the extensive pretraining required to overcome the aversive taste of ethanol. Work by Augier et al. (Psychopharmacology 231: 4561-4568, 2014) indicates that Wistar rats will self-administer alcohol without water deprivation, exposure to sweetened ethanol solutions or intermittent access to ethanol. We sought to replicate and extend the work of Augier et al. by comparing the acquisition of instrumental self-administration of ethanol in Lister-Hooded rats that had been previously saccharin faded (SF group) or not (NSF group). We also aimed to determine whether NMDA receptor antagonism with MK-801, given at memory reactivation, reduced subsequent ethanol-seeking behaviour in both groups of animals. Finally, we assessed the ethanol preference of SF and NSF rats using the two-bottle choice procedure. Both SF and NSF groups acquired instrumental self-administration of ethanol, though SF rats consumed fewer of the earned reinforcers. MK-801, given at memory reactivation, had different effects on NSF and SF rats: impairing the capacity of an ethanol-paired conditioned stimulus (CS) to support reinstatement in NSF rats, and enhancing it in SF rats. Finally, neither SF nor NSF rats showed a preference for ethanol. Our data support those of Augier et al. (Psychopharmacology 231: 4561-4568, 2014) that pretraining is unnecessary for rats to acquire instrumental self-administration of ethanol. Indeed, saccharin fading may produce a weaker memory that extinguishes more readily, thus accounting for the different effects of MK-801 on SF and NSF rats.

This study focuses on the relationship between the work process in a food and nutrition unit and workers' health, in the words of the participants themselves. Direct observation, a semi-structured interview, and focus groups were used to collect the data. The reference was the dialogue between human ergonomics and work psychodynamics. The results showed that work organization in the study unit represents a routine activity, the requirements of which in terms of the work situation are based on criteria set by the institution. Variability in the activities is influenced mainly by the available equipment, instruments, and materials, thereby generating improvisation in meal production that produces both a physical and psychological cost for workers. Dissatisfaction during the performance of tasks results mainly from the supervisory style and relationship to immediate superiors. Workers themselves proposed changes in the work organization, based on greater dialogue and trust between supervisors and the workforce. Finally, the study identifies the need for an intervention that encourages workers' participation as agents of change.

This study is aimed at finding out the relationship between long working hours, one of major job stress elements, and hearing impairment in unexposed workers to occupational and environmental noise. This study was performed on 1628 regular, full-time wage workers between the age of 25-64 who indicated in the survey of having no experience of exposure to noise, normal otoscopic findings, and not suffering from diabetes based on the data from the fifth Korea National Health and Nutrition Examination Survey (KNHANES 2010-2012). The average working hours per week was categorized into 40 h and lower group, more than 40 to 48 h group, more than 48 to 60 h group, and more than 60 h group. The groups were defined as suffering from low or high frequencies hearing impairment if the average hearing threshold for 0.5, 1, 2 kHz or 3, 4, 6 kHz in both ears exceeds 25 dB based on the pure tone audiometry. The association between average weekly working hours and hearing impairment was analyzed using logistic regression after gender stratification. The prevalences of low and high frequencies hearing impairment in male workers were 4.3 and 28.6 %, respectively, which were much higher than female's prevalence of 2.7 and 11.1 %. For male workers, no significant association was found between average weekly working hours and low and high frequencies hearing impairment. For female workers, odds ratios (OR) of low and high frequencies hearing impairment were 4.22 (95 % confidence interval (CI) 1.09-16.27) and 4.49 (95 % CI 1.73-11.67), respectively, after controlling for several related factors, such as, age, Body Mass Index (BMI), socio-economic status, health-related behavioral, and occupational characteristics variables, in the final model in the group working more than 60 h compared to the group working 40 h and lower. In addition, a dose-response relationship was observed that ORs of low and high frequencies hearing impairment were increased according to increasing average weekly working hours. The association between long working hours and hearing impairment in both low and high frequencies was significant in Korean female workers with a dose-response relationship. Therefore, the law to change the culture of long working hours should be enacted in order to protect the workers' health and improve the quality of life in Korean workers.

Supervising the uncanny: the play within the play.

PubMed

Leader, Carol

2015-11-01

The writer offers a combined experience in analysis and the performing arts to explore uncanny aspects of the unconscious subtext of the patient's inner drama; subtext which can remain hidden from view in supervision. Freud and Jung's understanding of uncanny experience is considered together with a painting from medieval alchemy and Matte Blanco's conceptions concerning the symmetrical nature of unconscious process. Theatre and the work of the theatre director and actor in approaching the multidimensional aspects of a play are then introduced. Finally clinical case material from group supervision demonstrates how the 'theatre of therapy' and the work of the supervisory couple and group promote the emergence of a more authentic conscious asymmetrical response to the patient's 'script' that can break the 'spell' of the transference/countertransference relationship. This in turn brings meaning to the underlying and implicit 'stage directions' that the patient has been unconsciously communicating. © 2015, The Society of Analytical Psychology.

To address these threats, conservation actions are proposed that focus on increased legal protection for the species and on the conservation of key sites and important habitats. Conservation could include implementing beneficial management practices, such as restoration of nest and roost sites, controlling predation, and reducing disturbance. Education and outreach programs are needed throughout the species’ range, especially for beach users and urban planners. Training programs will be necessary to ensure successful implementation of many of the priority conservation actions. Finally, a key first step in conserving this species across its range is the creation of a H. palliatus Working Group. Modelled after the U.S. American Oystercatcher Working Group this organization could unite researchers, conservationists, and educators from across the hemisphere to foster coordinated research, conservation action, and monitoring as outlined in this assessment.

The results of a workshop of 50 representatives from the public and private sector which investigated the potential joint development of the key technologies and mechanisms that will enable the permanent habitation of space are presented. The workshop is an initial step to develop a joint public/private assessment of new technology requirements of future space options, to share knowledge on required technologies that may exist in the private sector, and to investigate potential joint technology development opportunities. The majority of the material was produced in 5 working groups: (1) Construction, Assembly, Automation and Robotics; (2) Prospecting, Mining, and Surface Transportation; (3) Biosystems and Life Support; (4) Materials Processing; and (5) Innovative Ventures. In addition to the results of the working groups, preliminary technology development recommendations to assist in near-term development priority decisions are presented. Finally, steps are outlined for potential new future activities and relationships among the public, private, and academic sectors.

Recent work has studied multiple addictions using a matrix measure, which taps multiple addictions through single responses for each type. The present study investigated use of a matrix measure approach among former alternative high school youth (average age = 19.8 years) at risk for addictions. Lifetime and last 30-day prevalence of one or more of 11 addictions reviewed in other work (Sussman, Lisha & Griffiths, 2011) was the primary focus (i.e., cigarettes, alcohol, other/hard drugs, eating, gambling, Internet, shopping, love, sex, exercise, and work). Also, the co-occurrence of two or more of these 11 addictive behaviors was investigated. Finally, the latent class structure of these addictions, and their associations with other measures, was examined. We found that ever and last 30-day prevalence of one or more of these addictions was 79.2% and 61.5%, respectively. Ever and last 30-day co-occurrence of two or more of these addictions was 61.5% and 37.7%, respectively. Latent Class Analysis suggested two groups: a generally Non-addicted Group (67.2% of the sample) and a "Work Hard, Play Hard"-addicted Group that was particularly invested in addiction to love, sex, exercise, the Internet, and work. Supplementary analyses suggested that the single-response type self-reports may be measuring the addictions they intend to measure. We suggest implications of these results for future studies and the development of prevention and treatment programs, though much more validation research is needed on the use of this type of measure.

Background With Canada’s senior population increasing, there is greater demand for family physicians with enhanced skills in Care of the Elderly (COE). The College of Family Physicians Canada (CFPC) has introduced Certificates of Added Competence (CACs), one being in COE. Our objective is to summarize the process used to determine the Priority Topics for the assessment of competence in COE. Methods A modified Delphi technique was used, with online surveys and face-to-face meetings. The Working Group (WG) of six physicians acted as the nominal group, and a larger group of randomly selected practitioners from across Canada acted as the Validation Group (VG). The WG, and then the VG, completed electronic write-in surveys that asked them to identify the Priority Topics. Responses were compiled, coded, and tabulated to identify the topics and to calculate the frequencies of their selection. The WG used face-to-face meetings and iterative discussion to decide on the final topic names. Results The correlation between the initial Priority Topic list identified by the VG and that identified by the WG is 0.6793. The final list has 18 Priority Topics. Conclusion Defining the required competencies is a first step to establishing national standards in COE. PMID:29581816

Aim: to compare the bactericidal efficiency of conventional method and LAI for root canal decontamination. Material and method: 22 human single root teeth, extracted for periodontal problems, mechanically prepared up to ISO 25 at the working lenght were divided in 2 groups: after sterilization, the teeth were infected with enterococcus faecalis and incubated for 4 weeks. Group A: 10 teeth were irrigated with conventional hand technique (CI): 3ml of 5% NaClO were used for two times of 30s each and after washing with sterile bi-distilled water for 20s, a final irrigation was performed with 3ml of 17% EDTA. Group B: 10 teeth were irrigated with 3ml of NaClO and activated by erbium laser, two cycles of 30s; also the final irrigation with 3ml of 17% EDTA was activated by erbium laser. In both the groups a resting time of 30s was used between the two sessions to allow the reaction rate of NaClO. The Erbium laser 2940 nm (LightWalker AT, Fotona; Lublijana, Slovenia) was used with 50microsecond pulse duration, at 15Hz, 20mJ, with a 600micron PIPS tip. Two samples were used as positive and negative control.

Talking Science: The research evidence on the use of small group discussions in science teaching

2010-01-01

This paper reports the findings of two systematic reviews of the use and effects of small group discussions in high school science teaching. Ninety-four studies were included in an overview (systematic map) of work in the area, and 24 studies formed the basis of the in-depth reviews. The reviews indicate that there is considerable diversity in the topics used to promote small group discussions. They also demonstrate that students often struggle to formulate and express coherent arguments, and demonstrate a low level of engagement with tasks. The reviews suggest that groups function more purposefully, and understanding improves most, when specifically constituted such that differing views are represented, when some form of training is provided for students on effective group work, and when help in structuring discussions is provided in the form of "cues". Single-sex groups function more purposefully than mixed-sex groups, though improvements in understanding are independent of gender composition of groups. Finally, the reviews demonstrate very clearly that, for small group discussions to be effective, teachers and students need to be given explicit teaching in the skills associated with the development of arguments and the characteristics associated with effective group discussions. In addition to the substantive findings, the paper also reports on key features of the methods employed to gather and analyse data. Of particular note are the two contrasting approaches to data analysis, one adopting a grounded theory approach and the other drawing on established methods of discourse analysis.

To provide practical recommendations for evaluation and treatment of osteoporosis associated to endocrine diseases and nutritional conditions. Members of the Bone Metabolism Working Group of the Spanish Society of Endocrinology, a methodologist, and a documentalist. Recommendations were formulated according to the GRADE system (Grading of Recommendations, Assessment, Development, and Evaluation) to describe both the strength of recommendations and the quality of evidence. A systematic search was made in MEDLINE (Pubmed), using the following terms associated to the name of each condition: AND "osteoporosis", "fractures", "bone mineral density", and "treatment". Papers in English with publication date before 18 October 2011 were included. Current evidence for each disease was reviewed by two group members, and doubts related to the review process or development of recommendations were resolved by the methodologist. Finally, recommendations were discussed in a meeting of the Working Group. The document provides evidence-based practical recommendations for evaluation and management of endocrine and nutritional diseases associated to low bone mass or an increased risk of fracture. For each disease, the associated risk of low bone mass and fragility fractures is given, recommendations for bone mass assessment are provided, and treatment options that have shown to be effective for increasing bone mass and/or to decreasing fragility fractures are listed.

Behavior genetics of personality disorders: informing classification and conceptualization in DSM-5.

PubMed

South, Susan C; DeYoung, Nathaniel J

2013-07-01

Personality pathology is currently captured in the Diagnostic and Statistical Manual through 10 categorical personality disorder (PD) diagnoses grouped into three descriptive clusters. This classification system has been criticized by many for using discrete categories and arbitrary thresholds when making clinical decisions. To address these critiques, the DSM-5 Personality and Personality Disorders Work Group has put forth a proposal that significantly alters the structure and content of the DSM-IV PD section. If this DSM-5 Work Group has conducted its own systematic review of the empirical literature, this review has not been released or made widely available. As such, it is up to the psychology community at large to determine how well the suggested changes align with findings from extant PD research. The current article joins this effort by addressing the contribution of behavior genetic findings to the revision process for classification of PDs in DSM-5. First, we provide a brief review of the history of PD classification in the DSM. Next, we present an overview and rationale for each of the five major suggested changes to PD diagnoses. For each suggested change, we outline the available evidence from behavior genetics and interpretations of these findings. Finally, we offer a summary of considerations for PD classification as the DSM-5 moves forward. Review of the behavior genetics literature suggests that several features of the DSM-5 proposal, including the elimination of 4 PDs, merging clinical disorders and PDs on a single axis, and the implementation of a trait rating system, require significantly greater explication before a product is finalized.

Using project life-cycles as guide for timing the archival of scientific data and supporting documentation

The NASA Earth Science Data Systems Working Groups (ESDSWG) focuses on improving technologies and processes related to science discovery and preservation. One particular group, the Data Preservation Practices, is defining a set of guidelines to aid data providers in planning both what to submit for archival, and when to submit artifacts, so that the archival process can begin early in the project's life cycle. This has the benefit of leveraging knowledge within the project before staff roll off to other work. In this poster we describe various project archival use cases and identify possible archival life cycles that map closely to the pace and flow of work. To understand "archival life cycles", i.e., distinct project phases that produce archival artifacts such as instrument capabilities, calibration reports, and science data products, the workig group initially mapped the archival requirements defined in the Preservation Content Specification to the typical NASA project life cycle. As described in the poster, this work resulted in a well-defined archival life cycle, but only for some types of projects; it did not fit well for condensed project life cycles experienced within airborne and balloon campaigns. To understand the archival process for projects with compressed cycles, the working group gathered use cases from various communities. This poster will describe selected uses cases that provided insight into the unique flow of these projects, as well as proposing archival life cycles that map artifacts to projects with compressed timelines. Finally, the poster will conclude with some early recommendations for data providers, which will be captured in a formal Guidelines document - to be published in 2015.

US DOE-EM On-Site Disposal Cell Working Group - Fostering Communication On Performance Assessment Challenges

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

Seitz, Roger R.; Suttora, Linda C.; Phifer, Mark

On-site disposal cells are in use and being considered at several U.S. Department of Energy (USDOE) sites as the final disposition for large amounts of waste associated with cleanup of contaminated areas and facilities. These facilities are typically developed with regulatory oversight from States and/or the US Environmental Protection Agency (USEPA) in addition to USDOE. The facilities are developed to meet design standards for disposal of hazardous waste as well as the USDOE performance based standards for disposal of radioactive waste. The involvement of multiple and different regulators for facilities across separate sites has resulted in some differences in expectationsmore » for performance assessments and risk assessments (PA/RA) that are developed for the disposal facilities. The USDOE-EM Office of Site Restoration formed a working group to foster improved communication and sharing of information for personnel associated with these Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) disposal cells and work towards more consistent assumptions, as appropriate, for technical and policy considerations related to performance and risk assessments in support of a Record of Decision and Disposal Authorization Statement. The working group holds teleconferences, as needed, focusing on specific topics of interest. The topics addressed to date include an assessment of the assumptions used for performance assessments and risk assessments (PA/RAs) for on-site disposal cells, requirements and assumptions related to assessment of inadvertent intrusion, DOE Manual 435.1-1 requirements, and approaches for consideration of the long-term performance of liners and covers in the context of PAs. The working group has improved communication among the staff and oversight personnel responsible for onsite disposal cells and has provided a forum to identify and resolve common concerns.« less

The development of European standard (CEN) methods in support of European Directives for plastics materials and articles intended to come into contact with foodstuff.

PubMed

Ashby, R

1994-01-01

CEC Directives have been implemented for plastics materials and articles intended to come into contact with foodstuffs. These introduce limits upon the overall migration from plastics into food and food simulants. In addition, specific migration limits or composition limits for free monomer in the final article, have been set for some monomers. Agreed test methods are required to allow these Directives to be respected. CEN, the European Committee for Standardization, has created a working group to develop suitable test methods. This is 'Working Group 5, Chemical Methods of Test', of CEN Technical Committee TC 194, Utensils in contact with food. This group has drafted a ten part standard for determining overall migration into aqueous and fatty food simulants by total immersion, by standard cell, by standard pouch and by filling. This draft standard has been approved by CEN TC 194 for circulation for public comment as a provisional standard, i.e. as an ENV. Further parts of this standard are in preparation for determining overall migration at high temperatures, etc. Simultaneously, Working Group 5 is cooperating with the BCR (Community Bureau of Reference) to produce reference materials with certified values of overall migration. CEN TC 194 Working Group 5 is also drafting methods for monomers subject to limitation in Directive 90/128/EEC. Good progress is being made on the monomers of highest priority but it is recognized that developing methods for all the monomers subject to limitation would take many years. Therefore, collaboration with the BCR, the Council of Europe and others is taking place to accelerate method development.

Proteomics Standards Initiative: Fifteen Years of Progress and Future Work

PubMed Central

2017-01-01

The Proteomics Standards Initiative (PSI) of the Human Proteome Organization (HUPO) has now been developing and promoting open community standards and software tools in the field of proteomics for 15 years. Under the guidance of the chair, cochairs, and other leadership positions, the PSI working groups are tasked with the development and maintenance of community standards via special workshops and ongoing work.

The Proteomics Standards Initiative (PSI) of the Human Proteome Organization (HUPO) has now been developing and promoting open community standards and software tools in the field of proteomics for 15 years. Under the guidance of the chair, cochairs, and other leadership positions, the PSI working groups are tasked with the development and maintenance of community standards via special workshops and ongoing work. Among the existing ratified standards, the PSI working groups continue to update PSI-MI XML, MITAB, mzML, mzIdentML, mzQuantML, mzTab, and the MIAPE (Minimum Information About a Proteomics Experiment) guidelines with the advance of new technologies and techniques.

A diary study on work-related smartphone use, psychological detachment and exhaustion: examining the role of the perceived segmentation norm.

In this diary study, we examined the associations between daily work-related smartphone use and daily psychological detachment and daily work-related exhaustion within a group of smartphone owners. In addition, we studied the role of the perceived segmentation norm at the workplace as a moderator of the link between work-related smartphone use and detachment. A total of 70 employees using smartphones on initiative of their employer completed a diary questionnaire on 4 successive workdays (N = 268 data points). We hypothesized that work-related smartphone use is negatively related to psychological detachment and that psychological detachment, in turn, is negatively related to work-related exhaustion. Finally, we expected that especially employees who perceive a high segmentation norm at their workplace have difficulties to psychologically detach from work on days that they use their smartphone more intensively. Overall, the results of multilevel analyses supported these hypotheses. The findings emphasize the importance of a clear organizational policy regarding work-related smartphone use outside of work hours. PsycINFO Database Record (c) 2014 APA, all rights reserved.

Flippin' Fluid Mechanics - Using Online Technology to Enhance the In-Class Learning Experience

Webster, D. R.; Majerich, D. M.

2013-11-01

This study provides an empirical analysis of using online technologies and team problem solving sessions to shift an undergraduate fluid mechanics course from a traditional lecture format to a collaborative learning environment. Students were from two consecutive semesters of the same course taught by the same professor. One group used online technologies and solved problems in class and the other did not. Out of class, the treatment group watched 72 short (11 minutes, average) video lectures covering course topics and example problems being solved. Three times a week students worked in teams of two to solve problems on desktop whiteboard tablets while the instructor and graduate assistants provided ``just-in-time'' tutoring. The number of team problems assigned during the semester exceeded 100. Weekly online homework was assigned to reinforce topics. The WileyPlus online system generated unique problem parameters for each student. The control group received three-50 minute weekly lectures. Data include three midterms and a final exam. Regression results indicate that controlling for all of the entered variables, for every one more problem solving session the student attended, the final grade was raised by 0.327 points. Thus, if a student participated in all 25 of the team problem solving sessions, the final grade would have been 8.2 points higher, a difference of nearly a grade. Using online technologies and teamwork appeared to result in improved achievement, but more research is needed to support these findings.

Specific sublingual immunotherapy (SLIT) has been proved to be a safe and effective approach in respiratory allergy. However, further research is required on aspects such as patient selection, use of optimal dosing, effects on asthma, long-term effects, and management of adverse reactions. In addition, the widely heterogeneous nature of studies on SLIT performed to date and the application of the criteria for subcutaneous immunotherapy make it difficult for the prescribing clinician to draw accurate and useful conclusions. Therefore, the QUASAR Group (QUality in the Administration of SLIT in Allergic Rhinitis), which comprises allergologists with broad clinical experience in SLIT, investigated the latest research findings and available data on this approach. Working parties were formed in 3 different categories: selection of candidates for SLIT, treatment efficacy, and adverse reactions. We performed a PubMed search for articles that were representative of each category and found 850. From these, we finally selected 266 articles, which were reviewed to retrieve data on SLIT. Evidence for each clinical question was graded according to the Oxford classification. The resulting text was evaluated on 3 occasions by all the members of the group until the final version was agreed upon. In this version, we review available evidence on SLIT, particularly with pollens, which is the subject of most articles. In areas where evidence is insufficient, an alternative agreed upon by the members of the QUASAR group is presented. Finally, we propose algorithms for selecting candidates for SLIT and for management of adverse events.

Previous work from our group demonstrated the use of multiple input atlases to a modified multi-atlas framework (MAGeT-Brain) to improve subject-based segmentation accuracy. Currently, segmentation of the striatum, globus pallidus and thalamus are generated from a single high-resolution and -contrast MRI atlas derived from annotated serial histological sections. Here, we warp this atlas to five high-resolution MRI templates to create five de novo atlases. The overall goal of this work is to use these newly warped atlases as input to MAGeT-Brain in an effort to consolidate and improve the workflow presented in previous manuscripts from our group, allowing for simultaneous multi-structure segmentation. The work presented details the methodology used for the creation of the atlases using a technique previously proposed, where atlas labels are modified to mimic the intensity and contrast profile of MRI to facilitate atlas-to-template nonlinear transformation estimation. Dice's Kappa metric was used to demonstrate high quality registration and segmentation accuracy of the atlases. The final atlases are available at https://github.com/CobraLab/atlases/tree/master/5-atlas-subcortical.

In Asia, the healthcare system, populations and patterns of disease differ from Western countries. The current reports on the criteria for cardiac CT scans, provided by Western professional societies, are not appropriate for Asian cultures. The Asian Society of Cardiovascular Imaging, the only society dedicated to cardiovascular imaging in Asia, formed a Working Group and invited 23 Technical Panel members representing a variety of Asian countries to rate the 51 indications for cardiac CT in clinical practice in Asia. The indications were rated as 'appropriate' (7-9), 'uncertain' (4-6), or 'inappropriate' (1-3) on a scale of 1-9. The median score was used for the final result if there was no disagreement. The final ratings for indications were 33 appropriate, 14 uncertain and 4 inappropriate. And 20 of them are highly agreed (19 appropriate and 1 inappropriate). Specifically, the Asian representatives considered cardiac CT as an appropriate modality for Kawasaki disease and congenital heart diseases in follow up and in symptomatic patients. In addition, except for some specified conditions, cardiac CT was considered to be an appropriate modality for one-stop shop ischemic heart disease evaluation due to its general appropriateness in coronary, structure and function evaluation. This report is expected to have a significant impact on the clinical practice, research and reimbursement policy in Asia.

[Technical report on the 2009 influenza A (H1N1) pandemic].

PubMed

2010-01-01

Since its appearance in April 2009, the influenza A (H1N1) pandemic has been a subject of continued attention by national and international health authorities, as well as in the communication media. It has been six months since the first cases were published and the winter season has just ended in the southern hemisphere. Therefore, we now have quite extensive knowledge on the behaviour of the disease, its severity and the way it manifests itself in the child/adolescent population. The Spanish Paediatric Association commissioned its Evidence Based Medicine Working Group to prepare a technical report on the influenza pandemic. This report has been prepared following the highly structured working methodology proposed by the so-called Evidence Based Medicine (EBM). This methodology requires formulating clinical questions, carrying out a systematic review of the literature looking for research works that could answer them, the critical reading of these, evaluating their methodology quality and clinical importance and finally, establishing recommendations based on those studies considered valid and important as well as on good clinical judgement. The present report approaches all aspects of the influenza pandemic considered to be of interest: extent of the disease, clinical and laboratory diagnosis, physical prevention measures, vaccination and pharmacological treatment. The target population of the report are children and adolescents. Many of the considerations made may also be applied to other age groups. The primary objective of this report is to establish a group of recommendations which may serve as a generic framework for the prevention, diagnosis and treatment of the pandemic influenza in children and adolescents. The final targets of the report are paediatricians and also general/family doctors and nurses who look after children and adolescents. Copyright (c) 2009 Asociación Española de Pediatría.

Update of an occupational asthma-specific job exposure matrix to assess exposure to 30 specific agents.

We aimed to update an asthmagen job exposure matrix (JEM) developed in the late 1990s. Main reasons were: the number of suspected and recognised asthmagens has since tripled; understanding of the aetiological role of irritants in asthma and methodological insights in application of JEMs have emerged in the period. For each agent of the new occupational asthma-specific JEM (OAsJEM), a working group of three experts out of eight evaluated exposure for each International Standard Classification of Occupations, 1988 (ISCO-88) job code into three categories: 'high' (high probability of exposure and moderate-to-high intensity), 'medium' (low-to-moderate probability or low intensity) and 'unexposed'. Within a working group, experts evaluated exposures independently from each other. If expert assessments were inconsistent the final decision was taken by consensus. Specificity was favoured over sensitivity, that is, jobs were classified with high exposure only if the probability of exposure was high and the intensity moderate-to-high. In the final review, all experts checked assigned exposures and proposed/improved recommendations for expert re-evaluation after default application of the JEM. The OAsJEM covers exposures to 30 sensitisers/irritants, including 12 newly recognised, classified into seven broad groups. Initial agreement between the three experts was mostly fair to moderate (κ values 0.2-0.5). Out of 506 ISCO-88 codes, the majority was classified as unexposed (from 82.6% (organic solvents) to 99.8% (persulfates)) and a minority as 'high-exposed' (0.2% (persulfates) to 2.6% (organic solvents)). The OAsJEM developed to improve occupational exposure assessment may improve evaluations of associations with asthma in epidemiological studies and contribute to assessment of the burden of work-related asthma. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

2016-01-01

Abstract The aim of this study was to determine differences in glycolytic metabolite concentrations and work output in response to an all-out interval training session in 23 cyclists with at least 2 years of interval training experience (E) and those inexperienced (IE) in this form of training. The intervention involved subsequent sets of maximal intensity exercise on a cycle ergometer. Each set comprised four 30 s repetitions interspersed with 90 s recovery periods; sets were repeated when blood pH returned to 7.3. Measurements of post-exercise hydrogen (H+) and lactate ion (LA-) concentrations and work output were taken. The experienced cyclists performed significantly more sets of maximal efforts than the inexperienced athletes (5.8 ± 1.2 vs. 4.3 ± 0.9 sets, respectively). Work output decreased in each subsequent set in the IE group and only in the last set in the E group. Distribution of power output changed only in the E group; power decreased in the initial repetitions of set only to increase in the final repetitions. H+ concentration decreased in the third, penultimate, and last sets in the E group and in each subsequent set in the IE group. LA- decreased in the last set in both groups. In conclusion, the experienced cyclists were able to repeatedly induce elevated levels of lactic acidosis. Power output distribution changed with decreased acid–base imbalance. In this way, this group could compensate for a decreased anaerobic metabolism. The above factors allowed cyclists experienced in interval training to perform more sets of maximal exercise without a decrease in power output compared with inexperienced cyclists. PMID:28149346

Neck/shoulder and back pain in new graduate nurses: A growth mixture modeling analysis.

Although it is well known that musculoskeletal disorders are common among registered nurses, little longitudinal research has been conducted to examine this problem from nursing education to working life. The aim was to investigate the prevalence and incidence of neck/shoulder and back pain in nursing students in their final semester, and one and two years after graduation. Furthermore, to identify common trajectories of neck/shoulder and back pain, and explore sociodemographic and lifestyle-related factors, contextual factors and health outcome that might be characteristic of individuals in the various trajectories. Longitudinal study following nursing students from their final year of studies, with follow-ups one and two years after graduation. Nursing students who graduated from the 26 universities providing undergraduate nursing education in Sweden 2002 were invited to participate (N=1700). Of those asked, 1153 gave their informed consent. The participants answered postal surveys at yearly intervals. Descriptive statistics were used to analyze prevalence and incidence of pain, and growth mixture modeling was applied to identify different homogeneous clusters of individuals following similar trajectories in pain development across time. The prevalence of neck/shoulder and back pain remained constant over time (around 50% for neck/shoulder pain and just over 40% for back pain). Six different development trajectories for each symptom were found, reflecting patterns of stable pain levels or variation in levels over time: one symptom-free group, two decreasing pain groups, two increasing pain groups, and one chronic pain group. With few exceptions, the same factors (sex, children, chronic disease, working overtime, work absence, sickness presence, physical load, depression, self-rated health, sleep quality and muscular tension) were associated with neck/shoulder and back pain trajectories. Different types of physical load characterized new nurses with neck/shoulder pain and back pain respectively. The high prevalence of pain among nursing students and among new graduate nurses, suggests that it would be effective to implement preventive strategies already during nursing education, but they should also preferably continue after graduation. Many factors associated with pain in the neck/shoulder and back seem to be modifiable, and thereby constitute targets for preventive strategies. Copyright © 2013 Elsevier Ltd. All rights reserved.

As part of international efforts to develop and implement national models including the specification of ICF-based clinical data collection tools, the Italian rehabilitation community initiated a project to develop simple, intuitive descriptions of the ICF Rehabilitation Set, highlighting the core concept of each category in user-friendly language. This paper outlines the Italian experience in developing simple, intuitive descriptions of the ICF Rehabilitation Set as an ICF-based clinical data collection tool for Italy. Consensus process. Expert conference. Multidisciplinary group of rehabilitation professionals. The first of a two-stage consensus process involved developing an initial proposal for simple, intuitive descriptions of each ICF Rehabilitation Set category based on descriptions generated in a similar process in China. Stage two involved a consensus conference. Divided into three working groups, participants discussed and voted (vote A) whether the initially proposed descriptions of each ICF Rehabilitation Set category was simple and intuitive enough for use in daily practice. Afterwards the categories with descriptions considered ambiguous i.e. not simple and intuitive enough, were divided among the working groups, who were asked to propose a new description for the allocated categories. These proposals were then voted (vote B) on in a plenary session. The last step of the consensus conference required each working group to develop a new proposal for each and the same categories with descriptions still considered ambiguous. Participants then voted (final vote) for which of the three proposed descriptions they preferred. Nineteen clinicians from diverse rehabilitation disciplines from various regions of Italy participated in the consensus process. Three ICF categories already achieved consensus in vote A, while 20 ICF categories were accepted in vote B. The remaining 7 categories were decided in the final vote. The findings were discussed in light of current efforts toward developing strategies for ICF implementation, specifically for the application of an ICF-based clinical data collection tool, not only for Italy but also for the rest of Europe. Promising as minimal standards for monitoring the impact of interventions and for standardized reporting of functioning as a relevant outcome in rehabilitation.

The Tower of London (TOL) is a widely used instrument for assessing planning ability. Inhibition and (spatial) working memory are assumed to contribute to performance on the TOL, but findings about the relationship between these cognitive processes are often inconsistent. Moreover, the influence of specific properties of TOL problems on cognitive processes and difficulty level is often not taken into account. Furthermore, it may be expected that several planning strategies can be distinguished that cannot be extracted from the total score. In this study, a factor analysis and a latent class regression analysis were performed to address these issues. The results showed that 4 strategy groups that differed with respect to preplanning time could be distinguished. The effect of problem properties also differed for the 4 groups. Additional analyses showed that the groups differed on average planning performance but that there were no significant differences between inhibition and spatial working memory performance. Finally, it seemed that multiple factors influence performance on the TOL, the most important ones being the score measurements, the problem properties, and strategy use.

Large structures and tethers working group

The Large Structures and Tethers Working Group sought to clarify the meaning of large structures and tethers as they related to space systems. Large was assumed to mean that the characteristic length of the structure was greater than one of such relevant plasma characteristics as ion gyroradius or debey length. Typically, anything greater than or equal to the Shuttle dimensions was considered large. It was agreed that most large space systems that the tether could be better categorized as extended length, area, or volume structures. The key environmental interactions were then identified in terms of these three categories. In the following Working Group summary, these categories and the related interactions are defined in detail. The emphasis is on how increases in each of the three spatial dimensions uniquely determine the interactions with the near-Earth space environment. Interactions with the environments around the other planets and the solar wind were assumed to be similar or capable of being extrapolated from the near-Earth results. It should be remembered in the following that the effects on large systems do not just affect specific technologies but will quite likely impact whole missions. Finally, the possible effects of large systems on the plasma environment, although only briefly discussed, were felt to be of potentially great concern.

To examine the effect of authentic leadership and structural empowerment on the emotional exhaustion and cynicism of new graduates and experienced acute-care nurses. Employee empowerment is a fundamental component of healthy work environments that promote nurse health and retention, and nursing leadership is key to creating these environments. In a secondary analysis of data from two studies we compared the pattern of relationships among study variables in two Ontario groups: 342 new graduates with <2 years of experience and 273 nurses with more than 2 years of experience. A multi-group path analysis using Structural Equation Modelling indicated an acceptable fit of the final model (χ(2) = 17.52, df = 2, P < 0.001, CFI = 0.97, IFI = 0.97 and RMSEA = 0.11). Authentic leadership significantly and negatively influenced emotional exhaustion and cynicism through workplace empowerment in both groups. The authentic behaviour of nursing leaders was important to nurses' perceptions of structurally empowering conditions in their work environments, regardless of experience level, and ultimately contributed to lower levels of emotional exhaustion and cynicism. Leadership training for nurse managers may help develop the empowering work environments required in today's health-care organizations in order to attract and retain nurses. © 2012 Blackwell Publishing Ltd.

Although the prevalence of tobacco use is decreasing in many high-income countries, it is increasing in many low- and middle-income countries. The health and economic burden of increasing tobacco use and dependence is predictable and will have devastating effects in countries with limited resources, particularly for vulnerable populations such as pregnant women. We sought to review effective tobacco prevention and intervention strategies for decreasing tobacco use and secondhand smoke exposure before and during pregnancy in high-, middle-, and low-income countries. We reviewed several types of interventions, including population-level efforts (increasing tobacco prices, implementing tobacco control policies), community interventions, clinical interventions, and pharmacological treatments. A second purpose of this report is to present findings of an international expert working group that was convened to review the evidence and to establish research priorities in the following areas: (a) preventing the uptake and reducing tobacco use among girls and women of reproductive age; and (b) reducing tobacco use and secondhand smoke exposure among pregnant women. The working group considered the evidence on existing interventions in terms of burden of disease, intervention impact, intervention costs, feasibility of integration into existing services, uniqueness of the contribution, and overall feasibility. Finally, we present the working group's recommendations for intervention research priorities.

The American Society for Colposcopy and Cervical Pathology (ASCCP) Colposcopy Standards recommendations address the role of and approach to colposcopy and biopsy for cervical cancer prevention in the United States. The recommendations were developed by an expert working group appointed by ASCCP's Board of Directors. The ASCCP Quality Improvement Working Group developed evidence-based guidelines to promote best practices and reduce errors in colposcopy and recommended indicators to measure colposcopy quality. The working group performed a systematic review of existing major society and national guidelines and quality indicators. An initial list of potential quality indicators was developed and refined through successive iterative discussions, and draft quality indicators were proposed. The draft recommendations were then reviewed and commented on by the entire Colposcopy Standards Committee, posted online for public comment, and presented at the International Federation for Cervical Pathology and Colposcopy 2017 World Congress for further comment. All comments were considered, additional adjustments made, and the final recommendations approved by the entire Task Force. Eleven quality indicators were selected spanning documentation, biopsy protocols, and time intervals between index screening tests and completion of diagnostic evaluation. The proposed quality indicators are intended to serve as a starting point for quality improvement in colposcopy at a time when colposcopy volume is decreasing and individual procedures are becoming technically more difficult to perform.

In recent years, with socioeconomic changes in the society, the presence of women in the workplace is inevitable. The differences in working condition, especially for pregnant women, has adverse consequences like low birth weight. This study was conducted with the aim to model the relationship between working conditions, socioeconomic factors, and birth weight. This study was conducted in case-control design. The control group consisted of 500 women with normal weight babies, and the case group, 250 women with low weight babies from selected hospitals in Tehran. Data were collected using a researcher-made questionnaire to determine mothers' lifestyle during pregnancy with low birth weight with health-affecting social determinants approach. This questionnaire investigated women's occupational lifestyle in terms of working conditions, activities, and job satisfaction. Data were analyzed with SPSS-16 and Lisrel-8.8 software using statistical path analysis. The final path model fitted well (CFI =1, RMSEA=0.00) and showed that among direct paths, working condition (β=-0.032), among indirect paths, household income (β=-0.42), and in the overall effect, unemployed spouse (β=-0.1828) had the most effects on the low birth weight. Negative coefficients indicate decreasing effect on birth weight. Based on the path analysis model, working condition and socioeconomic status directly and indirectly influence birth weight. Thus, as well as attention to treatment and health care (biological aspect), special attention must also be paid to mothers' socioeconomic factors.

To determine the workplace needs of Western Australian midwives working in public metropolitan secondary hospitals. Using a three-round Delphi approach, Round 1 incorporated focus groups and a questionnaire. Fifteen focus groups were conducted with midwives also having the option of contributing through an open-ended questionnaire. During Round 2, 38 items reflecting seven themes were prioritised with a final ranking performed in Round 3. In total, 114 midwives participated in Round 1, 72 in Round 2 and 89 in Round 3. During Round 1, workplace needs identified as being met included: working across all areas of midwifery; ability to work in areas of interest; opportunity to work with low to moderate risk women; supportive colleagues; accessible parking; hospital close to home and friendly work atmosphere. Round 2 items revealed the five top unmet needs as: adequate midwifery staff coverage; access to maintained equipment; competitive pay scales; patient safety issues and opportunities to implement midwifery models. The top ranked needs from Round 3 included: recognising the unpredictable nature of midwifery services; provision of competent medical coverage, and adequate midwifery staff coverage. Demand for maternity services is unpredictable; however, in order to maintain a sustainable maternity workforce, WA midwives' prioritised needs would suggest health management focus upon expanding the availability of midwifery models of care, fostering flexible working conditions and ensuring collaboration between maternity health professionals occurs within clinically safe staffing levels.

The food industry regulates various aspects of food handler activities, according to legislation and customer expectations. The purpose of this paper is to provide a code of practice which delineates a set of working standards for food handler hygiene, handwashing, use of protective equipment, wearing of jewellery and body piercing. The code was developed by a working group of occupational physicians with expertise in both food manufacturing and retail, using a risk assessment approach. Views were also obtained from other occupational physicians working within the food industry and the relevant regulatory bodies. The final version of the code (available in full as Supplementary data in Occupational Medicine Online) therefore represents a broad consensus of opinion. The code of practice represents a set of minimum standards for food handler suitability and activities, based on a practical assessment of risk, for application in food businesses. It aims to provide useful working advice to food businesses of all sizes.

OBJECTIVE—To study the effectiveness of luteinising hormone releasing hormone (LHRH) analogues in improving final height in girls affected by early puberty.
PATIENTS—Forty six consecutive girls with onset of puberty aged 7.5-8.5 years randomly divided into two groups: one treated with 3.75 mg triptorelin intramuscularly every four weeks (group 1); and the other with no treatment (group 2).
RESULTS—Mean (SD) chronological age at onset of menarche was significantly higher in group 1 than in group 2 (11.9 (1.0) v 10.8 (0.7) years). However, mean (SD) height at menarche (152.7 (7.2) v 152.5(5.7) cm) and mean (SD) growth after menarche (4.9 (3.0) v 5.4(2.2) cm) were similar in both groups. The mean (SD) final height was similar in the two groups (group 1, 158.1 (6.2) cm; group 2, 158.6 (6.0) cm) and not significantly different from target height. Fourteen of 20 patients in group 1 and 12 of 18 patients in group 2 showed final height equal to or higher than target height. Final heights of girls with poor initial height prognosis were significantly lower than those of girls with good prognosis, but in patients with the same initial height prognosis, both groups showed final heights similar and not significantly different from their target heights.
CONCLUSIONS—LHRH analogue has no apparent effect on final height in subjects with onset of puberty between 7.5 and 8.5years.

To assess recurrence and complications in children with radial longitudinal deficiency treated with or without external fixator soft tissue distraction prior to centralization. Thirteen upper extremities treated with centralization alone were compared with 13 treated with ring fixator distraction followed by centralization. Resting wrist position between the 2 groups was compared before surgery, approximately 2 years after surgery (midterm), and at final follow-up, which was at a mean of 10 years for the centralization-alone group and 6 years for the distraction group. Radiographs were reviewed for hand-forearm angle, hand-forearm position, volar carpal subluxation, ulnar length, and physeal integrity. The clinical resting wrist position was improved significantly after surgery and at final follow-up in both groups, but recurrence was worse at final follow-up in the distraction group patients. Radiographically, in the centralization alone group, the hand-forearm angle improved from 53° before surgery to 13° at midterm but worsened to 27° at final follow-up. In the distraction group, the hand-forearm angle improved from 53° before surgery to 21° at midterm but worsened to 36° at final follow-up. The hand-forearm position improved between preoperative and final assessment in both groups, but at final follow-up, the centralization-alone group had a significantly better position. Volar subluxation was 4 mm improved in the centralization alone group and 2 mm worse in the distraction group at final follow-up. Centralization, with or without distraction with an external fixator, resulted in improved alignment of the wrist. Distraction facilitated centralization, but it did not prevent deformity recurrence and was associated with a worse final radial deviation and volar subluxation position compared with wrists treated with centralization alone.

To implement an antimicrobial stewardship (AS) elective course for second-year and third-year pharmacy students and to assess its impact on students' perceptions regarding the application of AS principles. A 2-credit elective course focusing on principles of AS incorporated prelecture didactic recordings with primary literature and guideline-based reading assignments, in-class active-learning group work and student-led presentations, and student-generated examination items. Perceptions were assessed by precourse and postcourse survey items. Graded course assessments included completion of preclass assignments (readings, prerecorded lecture and writing assessment items), in-class active participation and group presentations, a midpoint examination, and a final examination. An AS-themed elective course in a doctor of pharmacy curriculum incorporating preclass, self-directed learning and in-class group-based active-learning strategies positively impacted students' perceived understanding of AS strategies.

Because a traditionally instructed dental radiology lecture course is very time-consuming and labour-intensive, online courseware, including an interactive-learning module, was implemented to support the lectures. The purpose of this study was to evaluate the perceptions of students who have worked with web-based courseware as well as the effect on their results in final examinations. Users (n(3+4)=138) had access to the e-program from any networked computer at any time. Two groups (n(3)=71, n(4)=67) had to pass a final exam after using the e-course. Results were compared with two groups (n(1)=42, n(2)=48) who had studied the same content by attending traditional lectures. In addition a survey of the students was statistically evaluated. Most of the respondents reported a positive attitude towards e-learning and would have appreciated more access to computer-assisted instruction. Two years after initiating the e-course the failure rate in the final examination dropped significantly, from 40% to less than 2%. The very positive response to the e-program and improved test scores demonstrated the effectiveness of our e-course as a learning aid. Interactive modules in step with clinical practice provided learning that is not achieved by traditional teaching methods alone. To what extent staff savings are possible is part of a further study.

Many women suffer from health problems after giving birth, which can lead to sick leave. About 30% of Dutch workers are on sick leave after maternity leave. Structural contact of supervisors with employees on maternity leave, supported by early medical advice of occupational physicians, may increase the chances of return-to-work after maternity leave. In addition, to understand the process of sick leave and return-to-work after childbirth it is important to gain insight into which factors hinder return-to-work after childbirth, as well, as which prognostic factors lead to the development of postpartum health complaints. In this paper, the design of the Mom@Work study is described. The Mom@Work study is simultaneously a randomised controlled trial and a cohort study. Pregnant women working for at least 12 hours a week at one of the 15 participating companies are eligible to participate. The supervisors of these pregnant employees are randomised at 35 weeks pregnancy into the intervention group or control group. During maternity leave, supervisors in the intervention group contact their employee six weeks after delivery using a structured interview. When employees do not expect to return to their jobs at the end of their scheduled maternity leave due to health problems, the supervisor offers early support of the occupational physician. Supervisors in the control group have no structural contact with their employees during maternity leave. Measurements take place at 30 weeks pregnancy and at 6, 12, 24 and 52 weeks postpartum. In addition, cost data are collected. For the RCT, primary outcome measures are sick leave and return-to-work, and secondary outcome measures are costs, health, satisfaction with intervention and global feelings of recovery. Outcome measures for the cohort are pregnancy-related pelvic girdle pain, fatigue and depression. Finally, a number of prognostic factors for return-to-work and for the development of complaints will be measured. The Mom@Work study will provide important information about return-to-work of employees after giving birth. Results will give insight in prognosis of postpartum sick leave and complaints. Also, the role of supervisors and occupational physicians in successful return-to-work after childbirth will be clarified.

To develop system for students training in laparoscopic surgery by using of Wet-lab educational operating theatre. We have launched laparoscopic surgery teaching program for students of Ryazan State Medical University. This system includes several stages. At the first stage professional selection was carried out on 'dry' laparoscopic simulators among III-IV-year students of medical faculty. So, 10 people were selected. The second stage included theoretical and practical parts consisting of development of basic laparoscopic skills on 'dry' simulators. 5 students who scored the maximum points were admitted to the next stage. The third stage is working in Wet-lab operating theatre with a mentor. There were 10 sessions on 10 laboratory pigs. Final stage of our study compares two groups of participants: main group - 5 students who underwent above-described program and control group of 5 residents without experience for laparoscopic operations. The participants of the main group had significantly higher OSATS score compared with another group (20 vs. 10; p<0.05). Movements effectiveness estimated by measuring of movements trajectory total length was also higher in main group than in control group (6 vs. 20; p<0.05). Experts' subjective assessment according to 10-point scale was also higher for students than for interns (9 vs. 5, p<0.05). Participants in the main group required significantly less time to complete the task compared with the control group (40 vs. 90 minutes, p<0.05). Our experience has shown that training system with Wet-lab operating theatre is effective for quick and efficient training of medical students in main laparoscopic procedures. In our opinion, introduction of students into 'advanced' surgery from early age will make it possible to get finally highly professional specialists.

Does voltage predict return to work and neuropsychiatric sequelae following electrical burn injury?

Voltage has historically guided the acute management and long-term prognosis of physical morbidity in electrical injury patients; however, few large studies exist that include neuropsychiatric morbidity in final outcome analysis. This review compares high (>1000 V) to low (<1000 V) voltage injuries, focusing on return to work and neuropsychiatric sequelae following electrical burn injury. Patients with electrical injuries admitted to the University of North Carolina Jaycee Burn Center between 2000 and 2005 were prospectively entered into a trauma database, then retrospectively reviewed. Patients were divided into 4 cohorts: high voltage (>1000 V), low voltage (<1000 V), flash arc, and lightning. Demographics, hospital course, and follow-up were recorded to determine physical and neuropsychiatric morbidity. Differences among cohorts were tested for statistical significance. Over 5 years, 2548 patients were admitted to the burn center, including 115 patients with electrical injuries. There were 110 males and 5 females, with a mean age of 35 years (range, 0.75-65 years). The cause of the electrical injury was high voltage in 60 cases, low voltage in 25 cases, flash arc in 29 cases and lightning in 1 case. The mean total body surface area burn was 8% (range, 0%-52%). The etiology was work-related electrical injury in 85 patients. Mean follow-up period was 352 days with 13 (11%) patients lost to follow-up. Patients with high voltage injuries had significantly larger total body surface area burn, longer ICU stays, longer hospitalizations, and significantly higher rates of fasciotomy, amputation, nerve decompression and outpatient reconstruction, with 4 cases of renal failure and 2 deaths. In spite of these differences, high and low voltage groups experienced similar rates of neuropsychiatric sequelae, limited return to work and delays in return to work. Final impairment ratings for the high and low voltage groups were 17.5% and 5.3%, respectively. Electrical injuries often incur severe morbidity despite relatively small burn size and/or low voltage. When comparing high and low voltage injuries, similarities in endpoints such as neuropsychiatric sequelae, the need for late reconstruction, and failure to return to work challenge previous notions that voltage predicts outcome.

The perceptual chunking of speech: a demonstration using ERPs.

PubMed

Gilbert, Annie C; Boucher, Victor J; Jemel, Boutheina

2015-04-07

In tasks involving the learning of verbal or non-verbal sequences, groupings are spontaneously produced. These groupings are generally marked by a lengthening of final elements and have been attributed to a domain-general perceptual chunking linked to working memory. Yet, no study has shown how this domain-general chunking applies to speech processing, partly because of the traditional view that chunking involves a conceptual recoding of meaningful verbal items like words (Miller, 1956). The present study provides a demonstration of the perceptual chunking of speech by way of two experiments using evoked Positive Shifts (PSs), which capture on-line neural responses to marks of various groups. We observed listeners׳ response to utterances (Experiment 1) and meaningless series of syllables (Experiment 2) containing changing intonation and temporal marks, while also examining how these marks affect the recognition of heard items. The results show that, across conditions - and irrespective of the presence of meaningful items - PSs are specifically evoked by groups marked by lengthening. Moreover, this on-line detection of marks corresponds to characteristic grouping effects on listeners' immediate recognition of heard items, which suggests chunking effects linked to working memory. These findings bear out a perceptual chunking of speech input in terms of groups marked by lengthening, which constitute the defining marks of a domain-general chunking.

Background Weight management constitutes a substantial problem particularly among groups of low socio-economic status. Interventions at work places may be a solution, but high quality worksite interventions documenting prolonged weight loss are lacking. This paper presents results of an intervention aimed to achieve a 12 months weight loss among overweight health care workers. Methods Ninety-eight overweight female health care workers were randomized into an intervention or a reference group. The intervention consisted of diet, physical exercise and cognitive behavioral training during working hours 1 hour/week. The reference group was offered monthly oral presentations. Several anthropometric measures, blood pressure, cardiorespiratory fitness, maximal muscle strength, and musculoskeletal pain were measured before and after the 12-months intervention period. Data were analyzed by intention-to-treat analysis. Results The intervention group significantly reduced body weight by 6 kg (p < 0.001), BMI by 2.2 (p < 0.001) and body fat percentage by 2.8 (p < 0.001). There were no statistical reductions in the control group, resulting in significant differences between the two groups over time. Conclusions The intervention generated substantial reductions in body weight, BMI and body fat percentage among overweight female health care workers over 12 months. The positive results support the workplace as an efficient arena for weight loss among overweight females. Trial registration NCT01015716. PMID:22871173

There is much research about those who exit the labour market prematurely, however, comparatively little is known about people working longer and about their employment and working conditions. In this paper, we describe the employment and working conditions of men and women working between 65 and 80 years, and compare them with previous conditions of those retired in the same age group. Analyses are based on wave 4 data from the Survey of Health, Ageing and Retirement in Europe (SHARE) with information collected between 2009 and 2011 from 17,625 older men and women across 16 European countries. Besides socio-demographic and health-related factors (physical and mental health), the focus lies on employment conditions (e.g. employment status, occupational position and working hours) and on stressful working conditions, measured in terms of low control at work and effort-reward imbalance. In case of retired people, information on working conditions refer to the last job before retirement. Following descriptive analyses, we then conduct multivariable analyses and investigate how working conditions and poor health are related to labour market participation (i.e. random intercept models accounting for country affiliation and adjusted for potential confounders). Results illustrate that people working between the ages of 65 and 80 are more likely to be self-employed (either with or without employees) and work in advantaged occupational positions. Furthermore, findings reveal that psychosocial working conditions are generally better than the conditions retired respondents had in their last job. Finally, in contrast to those who work, health tends to be worse among retired people. In conclusion, findings deliver empirical evidence that paid employment beyond age 65 is more common among self-employed workers throughout Europe, in advantaged occupations and under-favourable psychosocial circumstances, and that this group of workers are in considerably good mental and physical health. This highlights that policies aimed at increasing the state pension age beyond the age of 65 years put pressure on specific disadvantaged groups of men and women.

Background and Aims: Recent work has studied multiple addictions using a matrix measure, which taps multiple addictions through single responses for each type. Methods: The present study investigated use of a matrix measure approach among former alternative high school youth (average age = 19.8 years) at risk for addictions. Lifetime and last 30-day prevalence of one or more of 11 addictions reviewed in other work (Sussman, Lisha & Griffiths, 2011) was the primary focus (i.e., cigarettes, alcohol, other/hard drugs, eating, gambling, Internet, shopping, love, sex, exercise, and work). Also, the co-occurrence of two or more of these 11 addictive behaviors was investigated. Finally, the latent class structure of these addictions, and their associations with other measures, was examined. Results: We found that ever and last 30-day prevalence of one or more of these addictions was 79.2% and 61.5%, respectively. Ever and last 30-day co-occurrence of two or more of these addictions was 61.5% and 37.7%, respectively. Latent Class Analysis suggested two groups: a generally Non-addicted Group (67.2% of the sample) and a “Work Hard, Play Hard”-addicted Group that was particularly invested in addiction to love, sex, exercise, the Internet, and work. Supplementary analyses suggested that the single-response type self-reports may be measuring the addictions they intend to measure. Discussion and Conclusions: We suggest implications of these results for future studies and the development of prevention and treatment programs, though much more validation research is needed on the use of this type of measure.

Orthodontics is the most widely practised form of specialist dentistry in New Zealand. To date, no known qualitative research has been published examining the work-life balance of practitioners. The aim of this study was to investigate the working lives and work-life balance of NZ orthodontists in order to generate an understanding of the reality of orthodontic specialist practice and its effects on orthodontists' professional and personal lives. Semi-structured interviews were conducted involving 19 practising orthodontists (four females, 15 males; mean age 50 years) from throughout New Zealand and selected for maximum variation in the sample. Transcribed interviews were analysed for themes using an applied grounded theory approach. A core category of 'practising orthodontist' was derived, and related themes were grouped under the sub-categories of: (a) NZ orthodontic specialist practice; (b) NZ specialist orthodontists; and (c) Work-life balance. The present paper reports on the final sub-category. Themes emerging from the work-life sub-category were further divided into two sub-themes of 'work' and 'life'. Themes in the 'work' subgroup included time off, injuries and illness, regrets, personality traits, job stress and criticism, establishing a practice, peer support and contact, and success in orthodontics. Themes in the 'life' sub-group were personal development, family life, life balance and interests outside work, and financial security. This was the first qualitative investigation of the orthodontic profession in New Zealand. The findings provided a valuable insight into the working lives of New Zealand orthodontists and effects on their day-today lives. It will be revealing and interesting to observe how the modernisation of orthodontic practice will affect the work-life balance of New Zealand orthodontists in the future.

Using the International Classification of Functioning, Disability and Health as a framework, this study investigates the impact of depression and diabetes mellitus on older workers' functioning (problems with concentration, physical functioning, need for recovery and work and social participation restrictions). The study focuses on how these chronic conditions, in their interaction with the work context, affect older workers' functioning, which may be an important precursor of early retirement. Older workers (≥ 45years) with depression (n=127) or diabetes mellitus (n=107) enrolled in the prospective Maastricht Cohort Study (MCS) were followed between October 2008 and October 2012. Linear, logistic and Cox regression analyses were performed to investigate the effect of these health conditions on workers' functioning compared to a reference group of older workers without a chronic condition (n=1612). The interaction with participants' working conditions (psychological job demands, decision latitude and strenuous work) was also analysed. Compared to the reference group, depression and diabetes mellitus were (over time) positively related with need for recovery caseness and restrictions in social participation but not with restrictions in work participation. Depression was positively related with concentration problems and need for recovery, whereas diabetes mellitus was negatively related with physical functioning. Finally, the relationship between functioning and depression and diabetes mellitus depends on working conditions. Older workers with depression or diabetes mellitus are vulnerable to losses in specific domains of functioning. The impact on functioning varies across working conditions, providing insight for disease-tailored preventive measures. Copyright © 2015 Elsevier Inc. All rights reserved.

2014-01-01

Biochemistry and molecular biology (BMB) students should demonstrate proficiency in the foundational concepts of the discipline and possess the skills needed to practice as professionals. To ascertain the skills that should be required, groups of BMB educators met in several focused workshops to discuss the expectations with the ultimate goal of clearly articulating the skills required. The results of these discussions highlight the critical importance of experimental, mathematical, and interpersonal skills including collaboration, teamwork, safety, and ethics. The groups also found experimental design, data interpretation and analysiand the ability to communicate findings to diverse audience to be essential skills. To aid in the development of appropriate assessments these skills are grouped into three categories, 1) Process of Science, 2) Communication and Comprehension of Science, and 3) Community of Practice Aspects of Science. Finally, the groups worked to align these competencies with the best practices in both teaching and in skills assessment. PMID:24019246

The effects of practice on movement distance and final position reproduction: implications for the equilibrium-point control of movements.

Predictions of two views on single-joint motor control, namely programming of muscle force patterns and equilibrium-point control, were compared with the results of experiments with reproduction of movement distance and final location during fast unidirectional elbow flexions. Two groups of subjects were tested. The first group practiced movements over a fixed distance (36 degrees), starting from seven different initial positions (distance group, DG). The second group practiced movements from the same seven initial positions to a fixed final location (location group, LG). Later, all the subjects were tested at the practiced task with their eyes closed, and then, unexpectedly for the subjects, they were tested at the other, unpracticed task. In both groups, the task to reproduce final position had lower indices of final position variability than the task to reproduce movement distance. Analysis of the linear regression lines between initial position and final position (or movement distance) also demonstrated a better (more accurate) performance during final position reproduction than during distance reproduction. The data are in a good correspondence with the predictions of the equilibrium-point hypothesis, but not with the predictions of the force-pattern control approach.

The farmer, the hunter, and the census taker: three distinct views of animal behavior.

2010-01-01

The purpose of this paper is to explore the relationship between evolutionary theory and ethology in the work of Konrad Lorenz, Niko Tinbergen and V.C. Wynne-Edwards, the farmer, hunter, and census taker of the title respectively. I am especially interested in the idea of the ethologists Lorenz and Tinbergen that animal behavior and human behavior were equally appropriated subjects of biological analysis. Their approach is contrasted with Wynne-Edwards's group selective account of the evolution of social behavior. Finally, I argue that Wynne-Edwards's dogged commitment to group selection theory helped create the theoretical space within which subsequent researchers could develop more careful analyses.

Development of highly porous crystalline titania photocatalysts

NASA Astrophysics Data System (ADS)

Marszewski, Michal

The objectives of this dissertation are the design, synthesis, and characterization of titania materials with surface area, porosity, crystallinity and doping tailored toward photocatalytic applications. Ultimately, the research should result in a strategy allowing the synthesis of titania with all these important features. The synthetic methods investigated in this research will include: i) soft-templating, ii) hard-templating, and iii) modified precursor strategy. Soft-templating strategy uses organic templates--either block copolymers or surfactants--that under specific conditions assemble into micelles, and later, these micelles are used to template the desired material around them. The resulting organic-inorganic composite is then calcined in air to remove the organic template and recover the final material with high surface area and large pore volume. This work explores 1) synthesis of titania materials in the presence of polymer templates, and the effects of different synthetic conditions on the structure of the resulting materials. Hard-templating, in contrast to soft-templating, uses inorganic templates. The hard template is introduced during the synthesis to cast its shape onto the fabricated material and removed afterwards, when the material has formed. The final material is an inverse replica of the hard template used, typically with a well-developed mesostructure. This work explores 1) hard templating synthesis of titania materials using silica and alumina, and 2) the effects of the template amount and type. The modified precursor strategy is a novel synthetic method, developed in this research, and designed specifically to achieve titania material with high surface area, large pore volume, high crystallinity, and possibly doping. The modified precursors are prepared by reacting generic titania precursors, such as titanium isopropoxide (TIPO), with organic acids, which results in substitution of some or all alkoxide groups in TIPO structure. The goal is to introduce new, easily carbonizable groups in TIPO structure so that the modified precursor can serve as titania and carbon precursor simultaneously. Subsequently, during carbonization in inert atmosphere, a carbon framework is formed that works as a scaffold, protecting titania during its crystallization. Afterwards, the carbon scaffold is removed by calcination in air. This work explores the modified precursor strategy by 1) preparing titania materials from TIPO modified with different carboxylic acids and 2) investigating the effect of the modifying acid on the properties of the carbon-titania composites and the final titania materials.

Cataplexy is the pathognomonic symptom of narcolepsy type 1 (NT1). Since it is considered difficult to be directly observed or documented by clinicians, its diagnosis relies mainly on history taking. Our study aimed at testing the feasibility of a standardized video recording procedure under emotional stimulation to document cataplexy in the diagnostic work-up of suspected hypersomnia of central origin. Two-hundred-eight consecutive patients underwent the diagnostic work-up and reached the final diagnosis of NT1 (n = 133), idiopathic hypersomnia or narcolepsy type 2 (IH/NT2 group, n = 33), or subjective excessive daytime sleepiness (sEDS group, n = 42). All subjects underwent a standardized video recording procedure while watching funny movies selected according to individual preferences, and a technician blind to clinical features reviewed the recordings to identify hypotonic phenomena that were finally confirmed by patients. The video recording under emotional stimulation captured hypotonic phenomena in 72.2%, 9.1% and 4.8% of NT1, IH/NT2, and sEDS subjects (p < 0.0001), respectively. When tested against CSF hypocretin deficiency, the documentation of a hypotonic episode at the test showed an area under the ROC curve of 0.823 ± 0.033 (p < 0.0001). NT1 patients under anticataplectic medications showed less frequently hypotonic episodes than untreated ones (48.0% vs 77.8%, p = 0.003). A standardized video recording procedure under emotional stimulation can help in the characterization of suspected hypersomnia of central origin. Further multi-center studies are warranted to extend the present findings and integrate a shared procedure for the laboratory work-up of narcolepsy. Copyright © 2017 Elsevier B.V.

Interprofessional education (IPE) is increasingly called upon to improve health care systems and patient safety. Our institution is engaged in a campus-wide IPE initiative. As a component of this initiative, a required online interprofessional patient-safety-focused course for a large group (300) of first-year medical, dental, and nursing students was developed and implemented. We describe our efforts with developing the course, including the use of constructivist and adult learning theories and IPE competencies to structure students' learning in a meaningful fashion. The course was conducted online to address obstacles of academic calendars and provide flexibility for faculty participation. Students worked in small groups online with a faculty facilitator. Thematic modules were created with associated objectives, online learning materials, and assignments. Students posted completed assignments online and responded to group members' assignments for purposes of group discussion. Students worked in interprofessional groups on a project requiring them to complete a root cause analysis and develop recommendations based on a fictional sentinel event case. Through project work, students applied concepts learned in the course related to improving patient safety and demonstrated interprofessional collaboration skills. Projects were presented during a final in-class session. Student course evaluation results suggest that learning objectives and content goals were achieved. Faculty course evaluation results indicate that the course was perceived to be a worthwhile learning experience for students. We offer the following recommendations to others interested in developing an in-depth interprofessional learning experience for a large group of learners: 1) consider a hybrid format (inclusion of some face-to-face sessions), 2) address IPE and broader curricular needs, 3) create interactive opportunities for shared learning and working together, 4) provide support to faculty facilitators, and 5) recognize your learners' educational level. The course has expanded to include students from additional programs for the current academic year.

Arthroscopic decompression not recommended in the treatment of rotator cuff tendinopathy: a final review of a randomised controlled trial at a minimum follow-up of ten years.

Ketola, S; Lehtinen, J T; Arnala, I

2017-06-01

Rotator cuff tendinopathy has a multifactorial origin. Rejecting the mechanistic theory has also led to abandoning operative treatment at initial presentation in the first line. Physiotherapy exercise programmes are the accepted first line treatment. The aim of this study was to assess the long-term additional benefits of subacromial decompression in the treatment of rotator cuff tendinopathy. This randomised controlled trial of 140 patients (52 men, 88 women, mean age 47.1 years; 18 to 60) with rotator cuff tendinopathy extended previous work up to a maximum of 13 years. The patients were randomised into two treatment groups: arthroscopic acromioplasty and a supervised exercise treatment and a similar supervised exercise treatment alone. Self-reported pain on a visual analogue scale (VAS) was the primary outcome measure. Secondary measures were disability, working ability, pain at night, Shoulder Disability Questionnaire score and the number of painful days during the three months preceding the final assessment. A total of 90 patients (64%) returned questionnaires at a mean 12 years after randomisation. On an intention-to-treat basis, both treatment groups reached statistically significant improvement compared with the initial VAS for pain, but there was no significant difference between groups. The same was true in the secondary outcome measures. Due to group changes, the results were also analysed per protocol: operated or not. No significant differences between the groups were found. The natural history of rotator cuff tendinopathy probably plays a significant role in the results in the long-term. Even though the patients who underwent operative treatment had a stronger belief in recovery, which is likely to be surgical and the effect of placebo, the exercise group obtained similar results. In the future, an optimum exercise regime should be searched for, as the most clinically and cost-effective conservative treatment for rotator cuff tendinopathy.

All of the work conducted under the auspices of DE-FC02-01ER25473 was characterized by exceptionally close collaboration with researchers at the Lawrence Berkeley National Laboratory (LBNL). This included having one of my graduate students - Sarah Williams - spend the summer working with Dr. Ann Almgren a staff scientist in the Center for Computational Sciences and Engineering (CCSE) which is a part of the National Energy Research Supercomputer Center (NERSC) at LBNL. As a result of this visit Sarah decided to work on a problem suggested by Dr. John Bell the head of CCSE for her PhD thesis, which she finishedmore » in June 2007. Writing a PhD thesis while working at one of the University of California (UC) managed DOE laboratories is a long established tradition at the University of California and I have always encouraged my students to consider doing this. For example, in 2000 one of my graduate students - Matthew Williams - finished his PhD thesis while working with Dr. Douglas Kothe at the Los Alamos National Laboratory (LANL). Matt is now a staff scientist in the Diagnostic Applications Group in the Applied Physics Division at LANL. Another one of my graduate students - Christopher Algieri - who was partially supported with funds from DE-FC02-01ER25473 wrote am MS Thesis that analyzed and extended work published by Dr. Phil Colella and his colleagues in 1998. Dr. Colella is the head of the Applied Numerical Algorithms Group (ANAG) in the National Energy Research Supercomputer Center at LBNL and is the lead PI for the APDEC ISIC which was comprised of several National Laboratory research groups and at least five University PI's at five different universities. Chris Algieri is now employed as a staff member in Dr. Bill Collins' research group at LBNL developing computational models for climate change research. Bill Collins was recently hired at LBNL to start and be the Head of the Climate Science Department in the Earth Sciences Division at LBNL. Prior to this he had been a Deputy Section Head at the National Center for Atmospheric Research in Colorado. My understanding is that Chris Algieri is the first person that Bill hired after coming to LBNL. The plan is that Chris Algieri will finish his PhD thesis while employed as a staff scientist in Bill's group. Both Sarah and Chris were supported in part with funds from DE-FC02-01ER25473. In Sarah's case she received support both while at U.C. Davis (UCD) taking classes and writing an MS thesis and during some of the time she was living in Berkeley, working at LBNL and finishing her PhD thesis. In Chris' case he was at U.C. Davis during the entire time he received support from DE-FC02-01ER25473. More specific details of their work are included in the report below. Finally my own research conducted under the auspices of DE-FC02-01ER25473 either involved direct collaboration with researchers at LBNL - Phil Colella and Peter Schwartz who is a member of Phil's Applied Numerical Algorithms Group - or was on problems that are closely related to research that has been and continues to be conducted by researchers at LBNL. Specific details of this work can be found below. Finally, I would like to note that the work conducted by my students and me under the auspices of this contract is closely related to work that I have performed with funding from my DOE MICS contract DE-FC02-03ER25579 'Development of High-Order Accurate Interface Tracking Algorithms and Improved Constitutive Models for Problems in Continuum Mechanics with Applications to Jetting' and with my CoPI on that grant Professor Greg Miller of the Department of Applied Science at UCD. In theory I tried to use funds from the SciDAC grant DE-FC02-01ER25473 to support work that directly involved implementing algorithms developed by my research group at U.C. Davis in software that was developed and is maintained by my SciDAC CoPI's at LBNL.« less

To explore the impact of at-work productivity loss on the total productivity cost by different instruments in patients recently diagnosed with RA and controls without RA. Cross-sectional data were collected from outpatients with RA between December 2007 and February 2008. The control group was formed by subjects without RA matched on age and gender. Absenteeism and presenteeism were estimated by the Quantity and Quality (QQ) Questionnaire, Work Productivity and Activity Impairment Questionnaire General Health V2.0 (WPAI-GH) and Health and Labor Questionnaire (HLQ) questionnaires. Differences between groups were tested by Mann-Whitney U-test. Costs were valued by the human capital approach. Data were available from 62 patients with a paid job and 61 controls. QQ- and WPAI-GH scores of presenteeism were moderately correlated (r = 0.61) while the HLQ presenteeism score correlated poorly with the other instruments (r = 0.34). The contribution of presenteeism on total productivity costs was estimated at ∼70% in the RA group. The mean costs per person per week due to presenteeism varied between €79 and €318 per week in the RA group, dependent on the instrument used. The costs due to presenteeism were about two to four times higher in the RA group compared with the control group. This study indicates that the impact of presenteeism on the total productivity costs in patients with RA is high. However, work productivity in individuals without RA was not optimal either, which implies a risk of overestimation of cost when a normal score is not taken into account. Finally, different presenteeism instruments lead to different results.

Modifying behaviour to reduce over-speeding in work-related drivers: an objective approach.

2014-03-01

The goal of this study was to utilise an objective measurement tool, via an on-board Diagnostic tool (OBDII), to explore the effectiveness of a behaviour modification intervention designed to reduce over-speed violations in a group of work-related drivers. It was predicted that over-speed violations would be decreased following participation in a behaviour modification intervention where drivers received weekly feedback on their speeding performance and goal setting exercises. The final analysis included the on-road behaviour of 16 drivers, all of whom completed each stage of the intervention programme. As predicted, over-speed violations significantly decreased from pre-test to post-test, after controlling for kilometres driven. These findings offer practical guidance for industry in developing interventions designed to improve work-related driving behaviour. Copyright © 2013 Elsevier Ltd. All rights reserved.

As we enter the 21st century, the sustainability of the biosphere is a global challenge that can best be met with a global response. This includes how we train and promote our next generation of research scientists in the emerging arenas of genome-enabled biology and a bio-based economy. It is this fundamental issue that formed the motivation for designing and conducting a shortcourse entitled “FACILIS 2014: Microbially-driven facilitation systems in environmental biotechnology” (hereafter “FACILIS”) presented here by the European Commission (EC)-United States (US) Task Force on Biotechnology Research. This WG was established in 1994 under the umbrella of the US-ECmore » Task Force on Biotechnology Research, a transatlantic collaborative group overseen by the US Office of Science and Technology Policy (OSTP) and the EC. The Environmental Biotechnology Working Group maintains several goals, including establishing research links between scientists in EU countries and the US and fostering the careers of junior scientists from both sides of the Atlantic to the global nature of scientific cooperation. To that end, a shortcourse was held at the University of Milan in Italy on July 12-25 2014 organized around cross-cutting themes of genomic science and designed to attract a stellar group of interdisciplinary early carrier researchers. A total of 22 students, 10 from the US and 12 from the EU participated. The course provided them with hands-on experience with the latest scientific methods in genomics and bioinformatics; using a format that combines lectures, laboratory research and field work with the final goal to enable researchers to finally turn data into knowledge.« less

Ocular trauma is a worldwide cause of visual morbidity, a significant proportion of which occurs in the industrial workplace and includes a spectrum of simple ocular surface foreign bodies, abrasions to devastating perforating injuries causing blindness. Being preventable is of social and medical concern. A prospective case series study, to know the profile of ocular trauma at a hospital caters exclusively to factory employees and their families, to co-relate their demographic and clinical profile and to identify the risk factors. Patients with ocular trauma who presented at ESIC Model hospital, Rajajinagar, Bangalore, from June 2010 to May 2011 were taken a detailed demographic data, nature and cause of injury, time interval between the time of injury and presentation along with any treatment received. Ocular evaluation including visual acuity, anterior and posterior segment findings, intra-ocular pressure and gonio-scopy in closed globe injuries, X-rays for intraocular foreign body, B-scan and CT scan were done. Data analyzed as per the ocular trauma classification group. The rehabilitation undertaken medically or surgically was analyzed. At follow-up, the final best corrected visual acuity was noted. A total of 306 cases of ocular trauma were reported; predominantly in 20-40 year age group (72.2%) and in men (75%). The work place related cases were 50.7%and of these, fall of foreign bodies led the list. Visual prognosis was poorer in road traffic accidents rather than work place injuries owing to higher occurrence of open globe injuries and optic neuropathy. Finally, 11% of injured cases ended up with poor vision. Targeting groups most at risk, providing effective eye protection, and developing workplace safety cultures may together reduce occupational eye injuries.

This study aimed at assessing effect of the four dimensions of work-family conflicts (strain and time-based work interference into family and family interference into work) on sleep disturbance in Malaysian working women. This cross-sectional study was conducted among 325 Malaysian married working women. Multiple-stage simple random sampling method was used to recruit women from public service departments of Malaysia. Self-administrated questionnaires were used to measure the study variables and data were analyzed using SPSS version 21. We found that high level of the four dimensions of work-family conflicts significantly increase sleep disturbance. Our analyses also revealed an age-dependent effect of the work-family conflict on sleep disturbance. Women in their 20 to 30 yr old suffer from sleep disturbance due to high level of time-based and strain-based work-interference into family. However, the quality of sleep among women aged 30-39 were affected by strain-based family-interference into work. Finally, women older than 40 yr had significantly disturbed sleep due to strain-based work-interference into family as well as time-based family interference into work. Our findings showed that sleep quality of working women might be disturbed by experiencing high level of work-family conflict. However, the effects of inter-role conflicts on sleep varied among different age groups.

A large body of research that has investigated substance dependence and working memory (WM) resources, yet no prior study has used a comprehensive test battery to examine the impact of chronic drug dependence on WM as a multi-component system. This study examined the efficiency of several WM components in participants who were chronic drug dependents. In addition, the functioning of the four WM components was compared among dependents of various types of drugs. In total, 128 chronic drug dependents participated in this study. Their average age was 38.48 years, and they were classified into four drug-dependence groups. Chronic drug dependents were compared with a 36-participant control group that had a mean age of 37.6 years. A WM test battery that comprised eight tests and that assessed each of four WM components was administered to each participant. Compared with the control group, all four groups of drug dependents had significantly poorer test performance on all of the WM tasks. Among the four groups of drug users, the polydrug group had the poorest performance scores on each of the eight tasks, and the performance scores of the marijuana group were the least affected. Finally, the forward digit span task and the logical memory tasks were less sensitive than other tasks when differentiating between marijuana users and the normal participants. The four components of WM are impaired among chronic drug dependents. These results have implications for the development of tools, classification methods and therapeutic strategies for drug dependents.

Assess the national prevalence of current workplace exposure to potential skin hazards, secondhand smoke (SHS), and outdoor work among various industry and occupation groups. Also, assess the national prevalence of chronic workplace exposure to vapors, gas, dust, and fumes (VGDF) among these groups. Data were obtained from the 2010 National Health Interview Survey (NHIS). NHIS is a multistage probability sample survey of the civilian non-institutionalized population of the US. Prevalence rates and their variances were calculated using SUDAAN to account for the complex NHIS sample design. The data for 2010 were available for 17,524 adults who worked in the 12 months that preceded interview. The highest prevalence rates of hazardous workplace exposures were typically in agriculture, mining, and construction. The prevalence rate of frequent handling of or skin contact with chemicals, and of non-smokers frequently exposed to SHS at work was highest in mining and construction. Outdoor work was most common in agriculture (85%), construction (73%), and mining (65%). Finally, frequent occupational exposure to VGDF was most common among mining (67%), agriculture (53%), and construction workers (51%). We identified industries and occupations with the highest prevalence of potentially hazardous workplace exposures, and provided targets for investigation and intervention activities.

Critical Thinking through Writing: Expressing Scientific Thought and Process in a Deaf Classroom

NASA Astrophysics Data System (ADS)

Manjarrez, Leslie

Within Deaf classrooms there is often a disconnect between academic areas and writing curriculums that develop in both common and academic language, where often classrooms focus solely on writing as a skill rather than as a method for producing language through an academic area. This work focuses on the development of academic language in ASL and English print of science. The curriculum is written to be implemented as a bilingual academic curriculum to support Deaf and Hard of Hearing students in various self contained classroom settings. Lessons are conducted in three Units, A B and C. Unit A focuses on research, thought and writing of preparatory materials in small groups. Unit B is comprised of procedural lessons on conducting x experiments and the evaluation of those experiments through mathematics. Unit C is a group of lessons that ties together Units A and B through writing and peer teaching as a method of concluding the work and presenting information in an effective manner. The success of the project was evaluated on the basis of student work, rubrics, and final works from the students. The results showed promise in aspects of Critical Thinking, writing development, and expression of new concepts in both ASL and English.

Gender differences in episodic memory and visual working memory including the effects of age.

2013-01-01

Analysing the relationship between gender and memory, and examining the effects of age on the overall memory-related functioning, are the ongoing goals of psychological research. The present study examined gender and age group differences in episodic memory with respect to the type of task. In addition, these subgroup differences were also analysed in visual working memory. A sample of 366 women and 330 men, aged between 16 and 69 years of age, participated in the current study. Results indicate that women outperformed men on auditory memory tasks, whereas male adolescents and older male adults showed higher level performances on visual episodic and visual working memory measures. However, the size of gender-linked effects varied somewhat across age groups. Furthermore, results partly support a declining performance on episodic memory and visual working memory measures with increasing age. Although age-related losses in episodic memory could not be explained by a decreasing verbal and visuospatial ability with age, women's advantage in auditory episodic memory could be explained by their advantage in verbal ability. Men's higher level visual episodic memory performance was found to result from their advantage in visuospatial ability. Finally, possible methodological, biological, and cognitive explanations for the current findings are discussed.

In intergroup conflict, self-sacrifice is stronger among pro-social individuals, and parochial altruism emerges especially among cognitively taxed individuals

Parochial altruism is decomposed in a tendency to benefit the in-group along with a tendency to ignore, derogate, and harm rivaling out-groups. Building off recent work suggesting that decisions to cooperate can be relatively fast and intuitive, we examine parochial altruism in intergroup conflict when cognitive deliberation is rendered difficult or not. Predictions were tested in an experiment using an incentivized Intergroup Prisoner’s Dilemma–Maximizing Differences Game with 95 subjects classified as either pro-social or pro-self being randomly allocated to high vs. low impulse-control conditions. Results showed, first of all, that self-sacrificial decisions to contribute were made faster than decisions not to contribute, and that faster decision time associated with more positive expectations of in-group members. Second, we observed that lowering impulse control with a difficult rather than easy Stroop Task increased the amount contributed to a pool that benefited in-group members while harming out-group members; thus reducing deliberation increased parochial altruism. Finally, results replicated earlier work showing that especially pro-social (vs. pro-self) individuals contributed more to the in-group and did not lower their contributions to the between-group pool that benefitted their in-group and, simultaneously, hurt the out-group. This pattern emerged independent of their impulse control. Thus, (in-group bounded) cooperation is more prominent among individuals with strong rather than weak other-regarding preferences. Moreover, the intuitive tendency to cooperate may have evolved in the context of intergroup conflict and therefore is sharp-edged—in-group bounded and including willingness to aggress out-groups.

Evidence suggests that cooperative learning and peer-assessment fosters students' ability to work with others and may lead to better cognitive outcomes and higher achievement. This work aimed to assess the use of an online collaborative tool for the teaching/learning and assessment of Microbiology. A total of 144 students were grouped and assigned to create wiki entries as well as to peer review wikis created by colleagues (peer-assessment process) using the Wiki module from Moodle Virtual Learning Environment (MVLE). MVLE actions log was used for tracking students' activity. The number of student's actions within wiki did not present a strong correlation with wiki scores, so it should not be used as a heavy evaluation parameter. The amount of work developed between members of the same group differed significantly, suggesting that final scores should be attributed individually. When peer-assessment process was implemented, the number of editing actions increased, suggesting that the peer-assessment strategy encourages the development of a better work. The vast majority of students execute the work in the last 10% of the period assigned for task development, which can be counter-productive for a truly collaborative work. Wiki revealed to be a useful tool for Microbiology teaching/learning and assessment, promoting collaborative work, promoting virtual mobility and facilitating the real-time monitoring of the students' work. This pedagogical project promoted also the involvement of students in their assessment process, encouraging their critical sense and quest for Excellency. © 2013 John Wiley & Sons A/S.

Limited Near and Far Transfer Effects of Jungle Memory Working Memory Training on Learning Mathematics in Children with Attentional and Mathematical Difficulties.

PubMed

Nelwan, Michel; Kroesbergen, Evelyn H

2016-01-01

The goal of this randomized controlled trial was to investigate whether Jungle Memory working memory training (JM) affects performance on working memory tasks, performance in mathematics and gains made on a mathematics training (MT) in school aged children between 9-12 years old ( N = 64) with both difficulties in mathematics, as well as attention and working memory. Children were randomly assigned to three groups and were trained in two periods: (1) JM first, followed by MT, (2) MT first, followed by JM, and (3) a control group that received MT only. Bayesian analyses showed possible short term effects of JM on near transfer measures of verbal working memory, but none on visual working memory. Furthermore, support was found for the hypothesis that children that received JM first, performed better after MT than children who did not follow JM first or did not train with JM at all. However, these effects could be explained at least partly by frequency of training effects, possibly due to motivational issues, and training-specific factors. Furthermore, it remains unclear whether the effects found on improving mathematics were actually mediated by gains in working memory. It is argued that JM might not train the components of working memory involved in mathematics sufficiently. Another possible explanation can be found in the training's lack of adaptivity, therefore failing to provide the children with tailored instruction and feedback. Finally, it was hypothesized that, since effect sizes are generally small, training effects are bound to a critical period in development.

Hemodynamic monitoring offers valuable information on cardiovascular performance in the critically ill, and has become a fundamental tool in the diagnostic approach and in the therapy guidance of those patients presenting with tissue hypoperfusion. From introduction of the pulmonary artery catheter to the latest less invasive technologies, hemodynamic monitoring has been surrounded by many questions regarding its usefulness and its ultimate impact on patient prognosis. The Cardiological Intensive Care and CPR Working Group (GTCIC-RCP) of the Spanish Society of Intensive Care and Coronary Units (SEMICYUC) has recently impulsed the development of an updating series in hemodynamic monitoring. Now, a final series of recommendations are presented in order to analyze essential issues in hemodynamics, with the purpose of becoming a useful tool for residents and critical care practitioners involved in the daily management of critically ill patients.

The American Society for Colposcopy and Cervical Pathology (ASCCP) Colposcopy Standards recommendations address the role of colposcopy and directed biopsy for cervical cancer prevention in the United States (US). The recommendations were developed by an expert working group appointed by ASCCP's Board of Directors. An extensive literature review was conducted and supplemented by a systematic review and meta-analysis of unpublished data. In addition, a survey of practicing colposcopists was conducted to assess current colposcopy practice in the US. Recommendations were approved by the working group members, and the final revisions were made based on comments received from the public. The recommendations cover terminology, risk-based colposcopy, colposcopy procedures, and colposcopy adjuncts. The ASCCP Colposcopy Standards recommendations are an important step toward raising the standard of colposcopy services delivered to women in the US. Because cervical cancer screening programs are currently undergoing important changes that may affect colposcopy performance, updates to some of the current recommendations may be necessary in the future.

Artuso, M.; et al.,

Sensors play a key role in detecting both charged particles and photons for all three frontiers in Particle Physics. The signals from an individual sensor that can be used include ionization deposited, phonons created, or light emitted from excitations of the material. The individual sensors are then typically arrayed for detection of individual particles or groups of particles. Mounting of new, ever higher performance experiments, often depend on advances in sensors in a range of performance characteristics. These performance metrics can include position resolution for passing particles, time resolution on particles impacting the sensor, and overall rate capabilities. In additionmore » the feasible detector area and cost frequently provides a limit to what can be built and therefore is often another area where improvements are important. Finally, radiation tolerance is becoming a requirement in a broad array of devices. We present a status report on a broad category of sensors, including challenges for the future and work in progress to solve those challenges.« less

Using the immediate release of the Working Group 1 Summary for Policymakers of the Intergovernmental Panel on Climate Change Fifth Assessment Report as a case study, this article seeks to describe what type of actors were most active during the summary release, the substance of the most propagated tweets during the summary release, and the media sources that attracted the most attention during the summary release. The results from the study suggest that non-elite actors, such as individual bloggers and concerned citizens, accounted for the majority of the most propagated tweets in the sample. This study also finds that the majority of the most propagated tweets in the sample focused on public understanding of the report. Finally, while mainstream media sources were the most frequently discussed media sources, a number of new media and science news and information sources compete for audience attention.

In Croatia, a new European Union (EU) member state since July 2013, there is already a shortage of around 3280 doctors to reach the European average. To investigate the emigration intentions of the current cohort of final year medical students at Zabreb School of Medicine. An electronic questionnaire was used in June 2013 to assess the attitudes of 232 final year medical students towards working conditions abroad and expectations for career opportunities in Croatia following accession to the EU. With an overall response rate of 87%, more than half of the surveyed students (106/202, 53%) intended to travel abroad, either for specialty (52/202, 26%) or subspecialty (54/202, 27%) training. More female students (58/135, 43%) than male students (17/62, 27%) indicated they would not emigrate. Most attractive emigration destinations were: Germany (34/121, 28%), USA (19/121, 16%), the UK (19/121, 16%), Switzerland (16/121, 13%) and Canada (11/121, 9%). The most important goals that respondents aimed to achieve through training abroad were to excel professionally (45/120, 38%), to prosper financially (20/120, 17%) and to acquire new experiences and international exposure (31/120, 26%). Students' motivating factors, goals for and positive beliefs about training abroad, as well as negative expectations regarding career opportunities in Croatia, may point towards actions that could be taken to help make Croatia a country that facilitates medical education and professional career development of young doctors.

Research on the mal-distribution of health care workers has focused mainly on physicians and nurses. To meet the Millennium Development Goal Five and the reproductive needs of all women, it is predicted that an additional 334,000 midwives are needed. Despite the on-going efforts to increase this cadre of health workers there are still glaring gaps and inequities in distribution. The objectives of this study are to determine the perceived barriers and motivators influencing final year midwifery students' acceptance of rural postings in Ghana, West Africa. An exploratory qualitative study using focus group interviews as the data collection strategy was conducted in two of the largest midwifery training schools in Ghana. All final year midwifery students from the two training schools were invited to participate in the focus groups. A purposive sample of 49 final year midwifery students participated in 6 focus groups. All students were women. Average age was 23.2 years. Glaser's constant comparative method of analysis was used to identify patterns or themes from the data. Three themes were identified through a broad inductive process: 1) social amenities; 2) professional life; and 3) further education/career advancement. Together they create the overarching theme, quality of life, we use to describe the influences on midwifery students' decision to accept a rural posting following graduation. In countries where there are too few health workers, deployment of midwives to rural postings is a continuing challenge. Until more midwives are attracted to work in rural, remote areas health inequities will exist and the targeted reduction for maternal mortality will remain elusive.

Introducing quality improvement to pre-qualification nursing students: evaluation of an experiential programme.

To evaluate a programme introducing quality improvement (QI) in nursing education. Betanien College of Nursing and clinical practices at hospitals in Bergen. 52 nursing students from a second year class working in 16 groups undertaking hospital based practical studies. Second year nursing students were assigned to follow a patient during a day's work and to record the processes of care from the patient's perspective. Data collected included waiting times, patient information, people in contact with the patient, investigations, and procedures performed. Students also identified aspects of practice that could be improved. They then attended a 2 day theoretical introductory course in QI and each group produced flow charts, cause/effect diagrams, and outlines of quality goals using structure, process, and results criteria to describe potential improvements. Each group produced a report of their findings. Main measures-A two-part questionnaire completed by the students before and after the intervention was used to assess the development of their understanding of QI. Evidence that students could apply a range of QI tools and techniques in the specific setting of a hospital ward was assessed from the final reports of their clinical attachments. The students had a significantly better knowledge of QI after the introductory course and group work than before it, and most students indicated that they considered the topic highly relevant for their later career. They reported that it was quite useful to observe one patient throughout one shift and, to some extent, they learned something new. Students found the introductory course and working in groups useful, and most thought the programme should be included in the curriculum for other nursing students. They considered it important for nurses in general to have knowledge about QI, indicating a high perceived relevance of the course. All 16 groups delivered reports of their group work which were approved by the tutors. Through the reports, all the groups demonstrated knowledge and ability to apply tools and techniques in their practical studies in a hospital setting. The introduction of a short experience-based programme into the practical studies of second year nursing students enabled them to learn about the concepts, tools, and techniques of continuous QI in a way that should provide them with the skills to undertake it as part of routine practice.

Since 2009 at Boston College, we have been offering a Research in Neuroscience course using cultured neurons in an in vitro model of stroke. The students work in groups to learn how to perform sterile animal cell culture and run several basic bioassays to assess cell viability. They are then tasked with analyzing the scientific literature in an attempt to identify and predict the intracellular pathways involved in neuronal death, and identify dietary antioxidant compounds that may provide protection based on their known effects in other cells. After each group constructs a hypothesis pertaining to the potential neuroprotection, we purchase one compound per group and the students test their hypotheses using a commonly performed viability assay.

2013-01-01

Since 2009 at Boston College, we have been offering a Research in Neuroscience course using cultured neurons in an in vitro model of stroke. The students work in groups to learn how to perform sterile animal cell culture and run several basic bioassays to assess cell viability. They are then tasked with analyzing the scientific literature in an attempt to identify and predict the intracellular pathways involved in neuronal death, and identify dietary antioxidant compounds that may provide protection based on their known effects in other cells. After each group constructs a hypothesis pertaining to the potential neuroprotection, we purchase one compound per group and the students test their hypotheses using a commonly performed viability assay. The groups generate quantitative data and perform basic statistics on that data to analyze it for statistical significance. Finally, the groups compile their data and other elements of their research experience into a poster for our departmental research celebration at the end of the spring semester. PMID:23805059

Objective. To implement an antimicrobial stewardship (AS) elective course for second-year and third-year pharmacy students and to assess its impact on students’ perceptions regarding the application of AS principles. Design. A 2-credit elective course focusing on principles of AS incorporated prelecture didactic recordings with primary literature and guideline-based reading assignments, in-class active-learning group work and student-led presentations, and student-generated examination items. Assessment. Perceptions were assessed by precourse and postcourse survey items. Graded course assessments included completion of preclass assignments (readings, prerecorded lecture and writing assessment items), in-class active participation and group presentations, a midpoint examination, and a final examination. Conclusion. An AS-themed elective course in a doctor of pharmacy curriculum incorporating preclass, self-directed learning and in-class group-based active-learning strategies positively impacted students’ perceived understanding of AS strategies.

The present work studies the molecular investigation of 40 thalassemic carriers using polymerase chain reaction. Forty thalassemic carriers who were registered and treated at Erbil thalassemic center and twenty apparently healthy children have been included in the present study. Ages of both groups ranged between 1-18 years. Four primers used to detect four different beta thalassemia mutations they were codon 8/9, codon 8, codon 41/42 and IVS-1-5. The two most common mutations detected among thalassemia group were Cd8/9 with 8 cases (20%) and Cd-8 with 6 cases (15%) followed by codon 41/42 with 4 cases (10%) which investigated and detected for the first time in Erbil governorate through the present study and finally IVS-1-5 with 3 cases (7.5%), while no any cases detected among control group.

Quantization of the nonlinear sigma model revisited

NASA Astrophysics Data System (ADS)

Nguyen, Timothy

2016-08-01

We revisit the subject of perturbatively quantizing the nonlinear sigma model in two dimensions from a rigorous, mathematical point of view. Our main contribution is to make precise the cohomological problem of eliminating potential anomalies that may arise when trying to preserve symmetries under quantization. The symmetries we consider are twofold: (i) diffeomorphism covariance for a general target manifold; (ii) a transitive group of isometries when the target manifold is a homogeneous space. We show that there are no anomalies in case (i) and that (ii) is also anomaly-free under additional assumptions on the target homogeneous space, in agreement with the work of Friedan. We carry out some explicit computations for the O(N)-model. Finally, we show how a suitable notion of the renormalization group establishes the Ricci flow as the one loop renormalization group flow of the nonlinear sigma model.

Peer support groups, also known as "self-help groups," provide a unique tool for helping veterans working through the military-to-civilian transition to achieve higher levels of social support and community integration. The number and variety of community-based peer support groups has grown to the point that there are now more visits to these groups each year than to mental health professionals. The focus of these groups on the provision of social support, the number and variety of groups, the lack of cost, and their availability in the community make them a natural transition tool for building community-based social support. A growing literature suggests that these groups are associated with measurable improvements in social support, clinical symptoms, self-efficacy and coping. For clinical populations, the combination of peer support groups and clinical care results in better outcomes than either alone. Given this evidence, we suggest clinical services use active referral strategies to help veterans engage in peer support groups as a means of improving community reintegration and clinical outcomes. Finally, suggestions for identifying appropriate peer support groups and assisting with active referrals are provided. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

2016-01-01

Ward rounds are an essential activity for interprofessional teams in hospital settings and represent complex tasks requiring not only medical knowledge but also communication skills, clinical technical skills, patient management skills and team-work skills. The present study aimed to analyse final year students', nurses' as well as physiotherapists' views on a simulation-based interprofessional ward round training. In two successive passes a total number of 29 final year students, nursing students and physiotherapy students (16 in the first run, 13 in the second) volunteered to participate in two standardized patient ward round scenarios: (1) patient with myocardial infarction, and (2) patient with poorly controlled diabetes. Views on the interprofessional ward round training were assessed using focus groups. Focus group based feedback contained two main categories (A) ward round training benefits and (B) difficulties. Positive aspects enfolded course preparation, setting of the training, the involvement of the participants during training and the positive learning atmosphere. Difficulties were seen in the flawed atmosphere and realization of ward rounds in the daily clinical setting with respect to inter-professional aspects, and course benefit for the different professional groups. The presented inter-professional ward round training represents a well received and valuable model of interprofessional learning. Further research should assess its effectiveness, processes of interprofessional interplay and transfer into clinical practice.

The aim of this study was to develop an appropriate definition for vaginal cuff and paracolpium clinical target volume (CTV) for postoperative intensity modulated radiation therapy in patients with uterine cervical cancer. A working subgroup was organized within the Radiation Therapy Study Group of the Japan Clinical Oncology Group to develop a definition for the postoperative vaginal cuff and paracolpium CTV in December 2013. The group consisted of 5 radiation oncologists who specialized in gynecologic oncology and a gynecologic oncologist. A comprehensive literature review that included anatomy, surgery, and imaging fields was performed and was followed by multiple discreet face-to-face discussions and e-mail messages before a final consensus was reached. Definitions for the landmark structures in all directions that demarcate the vaginal cuff and paracolpium CTV were decided by consensus agreement of the working group. A table was created that showed boundary structures of the vaginal cuff and paracolpium CTV in each direction. A definition of the postoperative cervical cancer vaginal cuff and paracolpium CTV was developed. It is expected that this definition guideline will serve as a template for future radiation therapy clinical trial protocols, especially protocols involving intensity modulated radiation therapy.

Aim: As part of the MaReCuM model curriculum at Medical Faculty Mannheim Heidelberg University, a final year rotation in ambulatory care was implemented and augmented to include ambulatory care simulation. In this paper we describe this ambulatory care simulation, the designated competency-based learning objectives, and evaluate the educational effect of the ambulatory care simulation training. Method: Seventy-five final year medical students participated in the survey (response rate: 83%). The control group completed the ambulatory rotation prior to the implementation of the ambulatory care simulation. The experimental group was required to participate in the simulation at the beginning of the final year rotation in ambulatory care. A survey of both groups was conducted at the beginning and at the end of the rotation. The learning objectives were taken from the National Competency-based Catalogue of Learning Objectives for Undergraduate Medical Education (NKLM). Results: The ambulatory care simulation had no measurable influence on students' subjectively perceived learning progress, the evaluation of the ambulatory care rotation, or working in an ambulatory care setting. At the end of the rotation participants in both groups reported having gained better insight into treating outpatients. At the beginning of the rotation members of both groups assessed their competencies to be at the same level. The simulated ambulatory scenarios were evaluated by the participating students as being well structured and easy to understand. The scenarios successfully created a sense of time pressure for those confronted with them. The ability to correctly fill out a narcotic prescription form as required was rated significantly higher by those who participated in the simulation. Participation in the ambulatory care simulation had no effect on the other competencies covered by the survey. Discussion: The effect of the four instructional units comprising the ambulatory care simulation was not measurable due to the current form or the measurement point at the end of the 12-week rotation. The reasons for this could be the many and statistically elusive factors relevant to the individual and the wide variety among final year rotation placements, the late point in time of the final survey, and the selection of simulated scenarios. The course is slated to undergo specific further development and should be supplemented with additional learning opportunities to ensure that the main learning objectives are covered. The description of the teaching format is meant to contribute to the ongoing development of medical education with an emphasis on competency in the areas of ambulatory care, communication, prevention and health promotion.

Background In recent years, with socioeconomic changes in the society, the presence of women in the workplace is inevitable. The differences in working condition, especially for pregnant women, has adverse consequences like low birth weight. Objectives This study was conducted with the aim to model the relationship between working conditions, socioeconomic factors, and birth weight. Patients and Methods This study was conducted in case-control design. The control group consisted of 500 women with normal weight babies, and the case group, 250 women with low weight babies from selected hospitals in Tehran. Data were collected using a researcher-made questionnaire to determine mothers’ lifestyle during pregnancy with low birth weight with health-affecting social determinants approach. This questionnaire investigated women’s occupational lifestyle in terms of working conditions, activities, and job satisfaction. Data were analyzed with SPSS-16 and Lisrel-8.8 software using statistical path analysis. Results The final path model fitted well (CFI =1, RMSEA=0.00) and showed that among direct paths, working condition (β=-0.032), among indirect paths, household income (β=-0.42), and in the overall effect, unemployed spouse (β=-0.1828) had the most effects on the low birth weight. Negative coefficients indicate decreasing effect on birth weight. Conclusions Based on the path analysis model, working condition and socioeconomic status directly and indirectly influence birth weight. Thus, as well as attention to treatment and health care (biological aspect), special attention must also be paid to mothers’ socioeconomic factors. PMID:24616796

NASA advanced design program. Design and analysis of a radio-controlled flying wing aircraft

NASA Technical Reports Server (NTRS)

1993-01-01

The main challenge of this project was to design an aircraft that will achieve stability while flying without a horizontal tail. The project focused on both the design, analysis and construction of a remotely piloted, elliptical shaped flying wing. The design team was composed of four sub-groups each of which dealt with the different aspects of the design, namely aerodynamics, stability and control, propulsion, and structures. Each member of the team initially researched the background information pertaining to specific facets of the project. Since previous work on this topic was limited, most of the focus of the project was directed towards developing an understanding of the natural instability of the aircraft. Once the design team entered the conceptual stage of the project, a series of compromises had to be made to satisfy the unique requirements of each sub-group. As a result of the numerous calculations and iterations necessary, computers were utilized extensively. In order to visualize the design and layout of the wing, engines and control surfaces, a solid modeling package was used to evaluate optimum design placements. When the design was finalized, construction began with the help of all the members of the project team. The nature of the carbon composite construction process demanded long hours of manual labor. The assembly of the engine systems also required precision hand work. The final product of this project is the Elang, a one-of-a-kind remotely piloted aircraft of composite construction powered by two ducted fan engines.

In Iran, inpatient group psychotherapy has been limited to transient practices for research purposes or fulfilling personal interest of therapists. The goal of this paper is to share and explain the experience of developing an inpatient group psychotherapy program in Roozbeh Psychiatric Hospital, Tehran, Iran. After theoretical delineation and preparation of a draft of the program guideline, two pilot sessions were held. Based on this initial experience a final treatment guideline was prepared. Afterwards, the program was continued for more than 1 year in a female ward at Roozbeh Psychiatric Hospital. The output of this exercise was a guideline that covers important topics in development of inpatient group psychotherapy. It is concluded that inpatient group psychotherapy has its unique challenges. Of the most important challenges that can be mentioned in this regard are the participation of patients with significant differences in levels of psychopathology and psychiatric signs and symptoms, and high comorbidity with specific personality traits or disorders. Other challenges relevant to the structure of the group include items such as very limited time for working through and inevitable out-of-group contacts. PMID:26576176

Impact of small groups with heterogeneous preference on behavioral evolution in population evacuation.

2015-01-01

Up to now, there have been a great number of mechanisms to explain the individual behavior and population traits, which seem of particular significance in evolutionary biology and social behavior analysis. Among them, small groups and heterogeneity are two useful frameworks to the above issue. However, vast majority of existing works separately consider both scenarios, which is inconsistent with realistic cases in our life. Here we propose the evolutionary games of heterogeneous small groups (namely, different small groups possess different preferences to dilemma) to study the collective behavior in population evacuation. Importantly, players usually face completely different dilemmas inside and outside the small groups. By means of numerous computation simulations, it is unveiled that the ratio of players in one certain small group directly decides the final behavior of the whole population. Moreover, it can also be concluded that heterogeneous degree of preference for different small groups plays a key role in the behavior traits of the system, which may validate some realistic social observations. The proposed framework is thus universally applicable and may shed new light into the solution of social dilemmas.

Electromyography Biofeedback Exergames to Enhance Grip Strength and Motivation.

Hand strength weakness affects the performance of most activities of daily living. This study aims to design, develop, and test an electromyography (EMG) biofeedback training system based on serious games to promote motivation and synchronization and proper work intensity in grip exercises for improving hand strength. An EMG surface sensor, soft balls with different stiffness and three exergames, conforms the system to drive videogame clues in response to EMG-inferred grip strength, while overseeing motivation. An experiment was designed to study the effect of performing handgrip (HG) exercises with the proposed system versus traditional exercises. Participants, organized into two groups, followed a training program for each hand. One group followed a HG exergame training (ET) with the dominant hand and traditional HG training with the nondominant hand and inverse sequence by the second group. Initial and final grip forces were measured using a digital dynamometer. Questionnaires evaluated motivation and user experience, and exercise performance was evaluated in terms of work and rest time percentage and maximal voluntary contraction percentage over contraction periods. Data were analyzed for statistically significant differences and increase of means. Participants showed significantly better exercise performance and higher grip forces, with sustained intrinsic motivation and user experience, with the ET. Improvement in force level arises evidently from the synchronized work-rest time pattern and appropriated intensity of the muscle activity. This leads to support that EMG biofeedback exergames improve motor neurons firing and resting.

Breaking the taboo: an interpretative phenomenological analysis of healthcare professionals' experience of caring for palliative patients with disgusting symptoms.

Disgusting symptoms are common in healthcare settings. Previous research has identified that healthcare professionals systematically avoid contact with patients with disgusting symptoms, potentially compromising patient care. Furthermore, research has highlighted disgust in healthcare professionals as a possible contributory factor to dehumanisation and abuse of patients. Given that healthcare professionals often feel that disgust is unprofessional, they may also feel unable to express or process disgust in their work, potentially impacting their emotional health, and contributing to burning out. Given the ubiquity of disgust in palliative care, we investigated how palliative healthcare professionals' experience and cope with disgust in their work, and how they are supported in doing so. We interviewed six palliative healthcare professionals and analysed their transcripts using Interpretative Phenomenological Analysis, from which four themes are discussed. Three key findings emerged. Firstly, participants were uncomfortable talking about disgust at work, reducing their access to support for disgust. Secondly, participants often neglected their own emotional needs, and as a result, sometimes become emotionally entangled with patients. Finally, participants were at risk of reducing vital socio-emotional support for patients with disgusting symptoms. Based on our analysis, we suggest interventions to counteract these effects.

To develop and implement an objective, reliable approach to surveillance for ventilator-associated events in adult patients. The Centers for Disease Control and Prevention (CDC) convened a Ventilator-Associated Pneumonia (VAP) Surveillance Definition Working Group in September 2011. Working Group members included representatives of stakeholder societies and organizations and federal partners. The Working Group finalized a three-tier, adult surveillance definition algorithm for ventilator-associated events. The algorithm uses objective, readily available data elements and can identify a broad range of conditions and complications occurring in mechanically ventilated adult patients, including but not limited to VAP. The first tier definition, ventilator-associated condition (VAC), identifies patients with a period of sustained respiratory deterioration following a sustained period of stability or improvement on the ventilator, defined by changes in the daily minimum fraction of inspired oxygen or positive end-expiratory pressure. The second tier definition, infection-related ventilator-associated complication (IVAC), requires that patients with VAC also have an abnormal temperature or white blood cell count, and be started on a new antimicrobial agent. The third tier definitions, possible and probable VAP, require that patients with IVAC also have laboratory and/or microbiological evidence of respiratory infection. Ventilator-associated events surveillance was implemented in January 2013 in the CDC's National Healthcare Safety Network. Modifications to improve surveillance may be made as additional data become available and users gain experience with the new definitions.

External exercise information provides no immediate additional performance benefit to untrained individuals in time trial cycling.

To determine the importance of the provision of external exercise information to the setting of the pacing strategy, in subjects unfamiliar with a cycling task. Twenty-two healthy, untrained cyclists (VO(2max), 50 ± 9 mL-(1)·kg-(1)·min-(1)) were randomly assigned to a control (CON) group or an experimental (EXP) group and two successive 4 km time trials (TT) were performed, separated by a 17 min recovery. The CON group received distance knowledge and distance feedback; the EXP group received neither, but knew that each TT was to be of the same distance. No significant difference in completion time (p>0.05) was observed between the groups for either time to complete TT one (TT1) (CON=443 ± 33 s versus EXP=471 ± 63 s) or time to complete TT two (time trial 2) (CON=461 ± 37 s versus EXP=501 ± 94 s). No significant difference in the final RPE was observed between groups. However, a significant interaction for RPE (rating of perceived exertion)×TT in the CON was observed (F7,70=5.32, p<0.05), with significantly higher RPE values in the final kilometre of TT2 (p<0.05). The lack of any performance improvement in either group, despite the differences in exercise information received, indicates both a reliance on the afferent feedback for setting a pacing strategy and slow learning effect from practice in subjects unfamiliar with the task. The modification in RPE profile observed in the CON, despite no performance improvement, suggests exercise perception based changes may pre-empt work rate based changes and thus not immediately translate to improved performance.

The objective of this paper is to present the distance education's contribution to developing health promotion in Chile, through evaluation of a postgraduate certificate program for professionals, and a training course for nurse technicians working in primary healthcare, with an 8-month follow-up after program completion. The program methodology was participatory, interactive and reflective, with mentoring support, exercises, group work and discussions as well as content pertinent to the needs of practice. The evaluation was quali-quantitative with an analysis of the student profile, the implementation process, outcomes at the end of the training and impacts on workplace changes. The results showed a high rate of student approval (87 and 76%), good academic performance and a high level of satisfaction with the methodology and knowledge delivered. The participants' final projects were adapted to local work places realities and were implemented by 62.6% of technicians and 43% of professionals, in addition to changes in work practices that favor health promotion. The level of fulfillment of participants' expectations was very high and the most frequent barriers to implementing the final project were lack of time and personnel, along with minimal support from management and low prioritization of health promotion. This study shows the effectiveness of a distance training model for professionals and technicians that can reach the most remote parts of the country, where there is no access to presencial training, with an educational program centered on work activities and current health challenges. © The Author 2016.

The authors present a new method of recognizing different human facial gestures through their neural activities and muscle movements, which can be used in machine-interfacing applications. Human-machine interface (HMI) technology utilizes human neural activities as input controllers for the machine. Recently, much work has been done on the specific application of facial electromyography (EMG)-based HMI, which have used limited and fixed numbers of facial gestures. In this work, a multipurpose interface is suggested that can support 2-11 control commands that can be applied to various HMI systems. The significance of this work is finding the most accurate facial gestures for any application with a maximum of eleven control commands. Eleven facial gesture EMGs are recorded from ten volunteers. Detected EMGs are passed through a band-pass filter and root mean square features are extracted. Various combinations of gestures with a different number of gestures in each group are made from the existing facial gestures. Finally, all combinations are trained and classified by a Fuzzy c-means classifier. In conclusion, combinations with the highest recognition accuracy in each group are chosen. An average accuracy >90% of chosen combinations proved their ability to be used as command controllers.

Role of methyl group number on SOA formation from aromatic hydrocarbons photooxidation under low NOx conditions

Li, L.; Tang, P.; Nakao, S.; Chen, C.-L.; Cocker, D. R., III

2015-11-01

Substitution of methyl groups onto the aromatic ring determines the SOA formation from the aromatic hydrocarbon precursor. This study links the number of methyl groups on the aromatic ring to SOA formation from aromatic hydrocarbons photooxidation under low NOx conditions (HC / NO > 10 ppb C : ppb). Aromatic hydrocarbons with increasing numbers of methyl groups are systematically studied. SOA formation from pentamethylbenzene and hexamethylbenzene are reported for the first time. A decreasing SOA yield with increasing number of methyl groups is observed. Linear trends are found in both f44 vs. f43 and O / C vs. H / C for SOA from aromatic hydrocarbons with zero to six methyl groups. An SOA oxidation state predictive method based on benzene is used to examine the effect of added methyl groups on aromatic oxidation under low NOx conditions. Further, the impact of methyl group number on density and volatility of SOA from aromatic hydrocarbons is explored. Finally, a mechanism for methyl group impact on SOA formation is suggested. Overall, this work suggests as more methyl groups are attached on the aromatic ring, SOA products from these aromatic hydrocarbons become less oxidized per mass/carbon.

["Vocational perspective" - concept and acceptance of a group treatment for patients with extensive work-related problems].

PubMed

Dorn, M; Bönisch, A; Ehlebracht-König, I

2011-02-01

The treatment programme "Vocational Perspective" was developed for patients with health-related social problems, e. g. long-term sick leave, job loss due to disability, job insecurity and psychosocial disabilities. It intends the patient-oriented imparting of information referring to social system, legal rights, earning capacity and occupational reintegration as well as an early feedback of the sociomedical assessment by the physicians. Participants during in-patient rehabilitation are supported to deal with their occupational situation; motivation to stay employed is strengthened. The group programme contains five psychoeducative modules and an additional sociomedical "ward round". The aim of the study was to examine the acceptance of the newly developed sociomedical vocational therapy module. A total of 179 patients participated in 21 "vocational perspective" seminars within the scope of a controlled quasi-experimental trial. In the experimental group the data on acceptance of the treatment was assessed by questionnaire at the end of the intervention. Experiences with implementation of the programme are described in order to complete the patient-related perspective. The identification of a demand for work-related interventions in medical rehabilitation seemed successful: Sociodemographic and socioeconomical parameters of the sample proved high risk in view of the social-medical perspective (poor education, high unemployment rates and long-term sick leave). Self-estimations revealed high suffering of the participants, e. g. due to the occupational situation, anxiety and depression, and confirmed high interest in work-related issues. The patients showed quite high acceptance of the programme (regarding importance of seminar, comprehensibility, usefulness of information, atmosphere of the group, mode and extent of the programme). 82.7% of the participants would recommend the programme to other people with work-related problems. Altogether, the experiences during the implementation of the programme can be described as positive. Nevertheless, organizing took much effort and the treatment was very demanding for the therapists. Finally, it is also necessary that the physicians agree to realize high transparency in the process of sociomedical assessment. The sociomedical programme "Vocational Perspective" helps patients to deal with relevant information referring to social system and occupational reintegration. Problematical sociomedical issues can be handled in a therapeutic way during rehabilitation process. Therefore, the programme can be used as meaningful supplement in regular medical rehabilitation. For final conclusions, the results of short-term and follow-up evaluations described elsewhere have to be considered. © Georg Thieme Verlag KG Stuttgart · New York.

Background: Pharmacists and medical doctors are two professional groups that very often receive their education and practice in the same environment. However, their approach to patient care and collaboration tends to be different and this may lead to both frustration and conflict which may adversely affect patient care. Personality has been identified as a psychological issue that could contribute to conflict in a work situation. Objective: To study the personality traits of a cohort of students studying pharmacy and medicine at the University of Malta in their first and final year. Methods: The Gordon Personal Profile – Inventory was administered to a cohort of pharmacy and medical students in their first year and once again administered to the same cohort who completed their course of study in their final year. Basic demographic data was also collected. Results: In first year the most pronounced traits for both student groups were those of Emotional Stability and Personal Relations. Over a period of five years, there were shifts in personality traits. In their final year pharmacy students were characterized by high scores for Cautiousness and Personal Relations while medical students exhibited medium scores in Cautiousness and Emotional Stability. Conclusion: The changes in personality traits over the duration of the course were not radical changes but rather that of traits becoming more pronounced. PMID:26759618

Collaborative testing: assessing teamwork and critical thinking behaviors in baccalaureate nursing students.

Wiggs, Carol M

2011-04-01

The purpose of this study was to foster teamwork and critical thinking behaviors in baccalaureate nursing students using a collaborative testing environment. Collaborative testing affords the nurse educator a unique opportunity to actively influence the development of critical thinking skills directly influencing the nursing student's ability to solve complex patient problems. Using a quasi-experimental approach exam scores from students in prior semesters were compared to students in several semesters using collaborative testing in one undergraduate course taught by the same faculty. In the experimental group collaborative testing was used in the two unit examinations, while the final examination remained individual. For collaborative testing the students were grouped by random assignment. They were not allowed the use of notes, textbooks, or other resource materials. Any student who wished to work alone was allowed do so and any student coming late (within 15 min of examination beginning) was required to work alone. Each student submitted individual examination answer forms, and groups were not required to reach consensus. Collaborative testing is one means to foster critical thinking by allowing students to solve complex patient problems within an examination environment. This better prepares them for national certification exams. Copyright © 2010 Elsevier Ltd. All rights reserved.

2010-01-30

Concern that underfunded and weak health systems are impeding the achievement of the health Millennium Development Goals in low-income countries led to the creation of a High Level Taskforce on Innovative International Financing for Health Systems in September, 2008. This report summarises the key challenges faced by the Taskforce and its Working Groups. Working Group 1 examined the constraints to scaling up and costs. Challenges included: difficulty in generalisation because of scarce and context-specific health-systems knowledge; no consensus for optimum service-delivery approaches, leading to wide cost differences; no consensus for health benefits; difficulty in quantification of likely efficiency gains; and challenges in quantification of the financing gap owing to uncertainties about financial commitments for health. Working Group 2 reviewed the different innovative mechanisms for raising and channelling funds. Challenges included: variable definitions of innovative finance; small evidence base for many innovative finance mechanisms; insufficient experience in harmonisation of global health initiatives; and inadequate experience in use of international investments to improve maternal, newborn, and child health. The various mechanisms reviewed and finally recommended all had different characteristics, some focusing on specific problems and some on raising resources generally. Contentious issues included the potential role of the private sector, the rights-based approach to health, and the move to results-based aid. The challenges and disagreements that arose during the work of the Taskforce draw attention to the many issues facing decision makers in low-income countries. International donors and recipient governments should work together to improve the evidence base for strengthening health systems, increase long-term commitments, and improve accountability through transparent and inclusive national approaches.

The experiences of new graduate midwives working in midwifery continuity of care models in Australia.

PubMed

Cummins, Allison M; Denney-Wilson, E; Homer, C S E

2015-04-01

midwifery continuity of care has been shown to be beneficial to women through reducing interventions and other maternal and neonatal morbidity. In Australia, numerous government reports recognise the importance of midwifery models of care that provide continuity. Given the benefits, midwives, including new graduate midwives, should have the opportunity to work in these models of care. Historically, new graduates have been required to have a number of years׳ experience before they are able to work in these models of care although a small number have been able to move into these models as new graduates. to explore the experiences of the new graduate midwives who have worked in midwifery continuity of care, in particular, the support they received; and, to establish the facilitators and barriers to the expansion of new graduate positions in midwifery continuity of care models. a qualitative descriptive study was undertaken framed by the concept of continuity of care. the new graduate midwives valued the relationship with the women and with the group of midwives they worked alongside. The ability to develop trusting relationships, consolidate skills and knowledge, be supported by the group and finally feeling prepared to work in midwifery continuity of care from their degree were all sub-themes. All of these factors led to the participants feeling as though they were 'becoming a real midwife'. this is the first study to demonstrate that new graduate midwives value working in midwifery continuity of care - they felt well prepared to work in this way from their degree and were supported by midwives they worked alongside. The participants reported having more confidence to practice when they have a relationship with the woman, as occurs in these models. Copyright © 2015 Elsevier Ltd. All rights reserved.

The impact of a disease management programme for type 2 diabetes on health-related quality of life: multilevel analysis of a cluster-randomised controlled trial.

Type 2 diabetes is a chronic disease associated with poorer health outcomes and decreased health related quality of life (HRQoL). The aim of this analysis was to explore the impact of a disease management programme (DMP) in type 2 diabetes on HRQoL. A multilevel model was used to explain the variation in EQ-VAS. A cluster-randomized controlled trial-analysis of the secondary endpoint HRQoL. Our study population were general practitioners and patients in the province of Salzburg. The DMP "Therapie-Aktiv" was implemented in the intervention group, and controls received usual care. Outcome measure was a change in EQ-VAS after 12 months. For comparison of rates, we used Fisher's Exact test; for continuous variables the independent T test or Welch test were used. In the multilevel modeling, we examined various models, continuously adding variables to explain the variation in the dependent variable, starting with an empty model, including only the random intercept. We analysed random effects parameters in order to disentangle variation of the final EQ-VAS. The EQ-VAS significantly increased within the intervention group (mean difference 2.19, p = 0.005). There was no significant difference in EQ-VAS between groups (mean difference 1.00, p = 0.339). In the intervention group the improvement was more distinct in women (2.46, p = 0.036) compared to men (1.92, p = 0.063). In multilevel modeling, sex, age, family and work circumstances, any macrovascular diabetic complication, duration of diabetes, baseline body mass index and baseline EQ-VAS significantly influence final EQ-VAS, while DMP does not. The final model explains 28.9% (EQ-VAS) of the total variance. Most of the unexplained variance was found on patient-level (95%) and less on GP-level (5%). DMP "Therapie-Aktiv" has no significant impact on final EQ-VAS. The impact of DMPs in type 2 diabetes on HRQoL is still unclear and future programmes should focus on patient specific needs and predictors in order to improve HRQoL.

2018-01-01

Independent component analysis (ICA) has been widely applied to identify intrinsic brain networks from fMRI data. Group ICA computes group-level components from all data and subsequently estimates individual-level components to recapture inter-subject variability. However, the best approach to handle artifacts, which may vary widely among subjects, is not yet clear. In this work, we study and compare two ICA approaches for artifacts removal. One approach, recommended in recent work by the Human Connectome Project, first performs ICA on individual subject data to remove artifacts, and then applies a group ICA on the cleaned data from all subjects. We refer to this approach as Individual ICA based artifacts Removal Plus Group ICA (IRPG). A second proposed approach, called Group Information Guided ICA (GIG-ICA), performs ICA on group data, then removes the group-level artifact components, and finally performs subject-specific ICAs using the group-level non-artifact components as spatial references. We used simulations to evaluate the two approaches with respect to the effects of data quality, data quantity, variable number of sources among subjects, and spatially unique artifacts. Resting-state test-retest datasets were also employed to investigate the reliability of functional networks. Results from simulations demonstrate GIG-ICA has greater performance compared to IRPG, even in the case when single-subject artifacts removal is perfect and when individual subjects have spatially unique artifacts. Experiments using test-retest data suggest that GIG-ICA provides more reliable functional networks. Based on high estimation accuracy, ease of implementation, and high reliability of functional networks, we find GIG-ICA to be a promising approach. PMID:26859308

The IAVCEI Commission on Volcanic Hazards and Risk set up a working group on Hazard Maps in 2014. Since then, the group has led or co-organised three major workshops, and organized two thematic conference sessions. In particular we have initiated a series of workshops, named the "State of the Hazard Map" which we plan to continue (the first was held at COV8 (State of the Hazard Map 1) and second at COV9 (State of the Hazard Map 2) and the third will be held at IAVCEI General Assembly in Portland. The broad aim of these activities is to work towards an IAVCEI-endorsed considerations or guidelines document for volcanic hazard map generation. The workshops have brought together people from around the world working on volcanic hazard maps, and have had four primary objectives: 1) to review (and collect further data on) the diverse variety of methods and rationales currently used to develop maps; 2) to openly discuss approaches and experiences regarding how hazard maps are interpreted and used by different groups; 3) to discuss and prepare the IAVCEI Guidelines document; and lastly, 4) Discuss options for finalizing, publishing and disseminating the Guidelines document (e.g. wiki, report, open-source publication). This presentation will provide an update of the results and outcomes of those initiatives. This includes brief outcomes of the reviews undertaken, a survey that has been constructed in order to gather additional data, the planned structure for the guidelines documents and a summary of the key findings to date. The majority of the participants of these activities so far have come from volcano observatories or geological surveys, as these institutions commonly have primary responsibility for making operational hazard map. It is important however that others in the scientific community that work on quantification of volcanic hazard contribute to these guidelines. We therefore invite interested parties to become involved.

Obstetrician-gynecologists (OB-GYNs) are the fourth largest group of physicians and the only specialty dedicated solely to women's health care. The specialty is unique in providing 24-hour inpatient coverage, surgical care and ambulatory preventive health care. This article identifies and reviews changes in the OB-GYN workforce, including more female OB-GYNs, an increasing emphasis on work-life balance, more sub-specialization, larger group practices with more employed physicians and, finally, an emphasis on quality and performance improvement. It then describes the evolution of the OB-GYN hospitalist movement to date and the role of OB-GYN hospitalists in the future with regard to these workforce changes. Copyright © 2015 Elsevier Inc.

The effect on cardiovascular risk factors of migration from rural to urban areas in Peru: PERU MIGRANT Study

PubMed Central

Miranda, J Jaime; Gilman, Robert H; García, Héctor H; Smeeth, Liam

2009-01-01

Background Mass-migration observed in Peru from the 1970s occurred because of the need to escape from politically motivated violence and work related reasons. The majority of the migrant population, mostly Andean peasants from the mountainous areas, tends to settle in clusters in certain parts of the capital and their rural environment could not be more different than the urban one. Because the key driver for migration was not the usual economic and work-related reasons, the selection effects whereby migrants differ from non-migrants are likely to be less prominent in Peru. Thus the Peruvian context offers a unique opportunity to test the effects of migration. Methods/Design The PERU MIGRANT (PEru's Rural to Urban MIGRANTs) study was designed to investigate the magnitude of differences between rural-to-urban migrant and non-migrant groups in specific CVD risk factors. For this, three groups were selected: Rural, people who have always have lived in a rural environment; Rural-urban, people who migrated from rural to urban areas; and, Urban, people who have always lived in a urban environment. Discussion Overall response rate at enrolment was 73.2% and overall response rate at completion of the study was 61.6%. A rejection form was obtained in 282/323 people who refused to take part in the study (87.3%). Refusals did not differ by sex in rural and migrant groups, but 70% of refusals in the urban group were males. In terms of age, most refusals were observed in the oldest age-group (>60 years old) in all study groups. The final total sample size achieved was 98.9% of the target sample size (989/1000). Of these, 52.8% (522/989) were females. Final size of the rural, migrant and urban study groups were 201, 589 and 199 urban people, respectively. Migrant's average age at first migration and years lived in an urban environment were 14.4 years (IQR 10–17) and 32 years (IQR 25–39), respectively. This paper describes the PERU MIGRANT study design together with a critical analysis of the potential for bias and confounding in migrant studies, and strategies for reducing these problems. A discussion of the potential advantages provided by the case of migration in Peru to the field of migration and health is also presented. PMID:19505331

2013-12-01

This study investigates the impact of collaborative reflections on teachers' inquiry teaching practices and identifies supportive actions relating to their professional development. Three science teachers in the same elementary school worked as a cooperative and collaborative group. They attended workshops and worked collaboratively through observing colleagues' teaching practices and discussing with university professors about their own inquiry teaching. The pre- and post-treatment classroom observations and comparisons of their teaching reveal that the three teachers were more focussed on asking inquiry-oriented questions in the post-treatment teaching. With additional qualitative data analysis, this study identified supportive resources of professional development. Workshop training sessions and sample unit served as the initiative agent in the beginning stage. Discussions with peers and reflective observation of peer teaching acted as a facilitative agent. Finally, student responses and researchers' on-site visit comments worked as a catalytic agent for their professional development.

National probability surveys indicate that most individuals with schizophrenia and other severe mental illnesses are not employed. This multisite study tested the effectiveness of supported employment (SE) models combining clinical and vocational rehabilitation services to establish competitive employment. We randomly assigned 1273 outpatients with severe mental illness from 7 states in the United States to an experimental SE program or to a comparison or a services-as-usual condition, with follow-up for 24 months. Participants were interviewed semiannually, paid employment was tracked weekly, and vocational and clinical services were measured monthly. Mixed-effects random regression analysis was used to predict the likelihood of competitive employment, working 40 or more hours in a given month, and monthly earnings. Cumulative results during 24 months show that experimental group participants (359/648 [55%]) were more likely than those in the comparison programs (210/625 [34%]) to achieve competitive employment (chi(2) = 61.17; P<.001). Similarly, patients in experimental group programs (330/648 [51%]) were more likely than those in comparison programs (245/625 [39%]) to work 40 or more hours in a given month (chi(2) = 17.66; P<.001). Finally, participants in experimental group programs had significantly higher monthly earnings than those in the comparison programs (mean, US 122 dollars/mo [n=639] vs US 99 dollars/mo [n=622]); t(1259) = -2.04; P<.05). In the multivariate longitudinal analysis, experimental condition subjects were more likely than comparison group subjects to be competitively employed, work 40 or more hours in a given month, and have higher earnings, despite controlling for demographic, clinical, work history, disability beneficiary status, and study site confounders. Moreover, the advantage of experimental over comparison group participants increased during the 24-month study period. The SE models tailored by integrating clinical and vocational services were more effective than services as usual or unenhanced services.

General patterns of managerial approaches to work motivation: Implications for rehabilitation professionals involved in occupational rehabilitation.

PubMed

Murphy, G C; Foreman, P

1993-03-01

Calls for rehabilitation counselors to learn more about the world of work have been recently repeated. The validity of these calls is suggested by a group of studies which indicate that the rehabilitation counseling literature has an established emphasis on matters of counseling and adjustment rather than on matters related to behavior in organizations. A survey of rehabilitation counsellors' beliefs about key topics in organizational behavior indicates that their beliefs are often discrepant with those of practicing managers and supervisors. A summary of dominant models of work motivation adopted by managerial workers is presented and some implications for occupational rehabilitation practice identified. Finally, some contemporary literature relevant to managerial approaches to employee motivation are identified and it is suggested that familiarity with this literature could assist rehabilitation practitioners move from a more narrow occupational rehabilitation role to a broader involvement in organizational life via the expansion of the disability management approach in work organizations.

The authors sought to evaluate the efficacy and safety of ABT-126, a selective α7 nicotinic receptor partial agonist, in stable patients with schizophrenia. A 12-week, double-blind, placebo-controlled, parallel-group phase 2 study was conducted in 22 centers in the United States. Clinically stable patients with schizophrenia were randomly assigned to receive once-daily dosing with 10 mg of ABT-126, 25 mg of ABT-126, or placebo. The primary efficacy measure was change from baseline to week 12 on the MATRICS Consensus Cognitive Battery (MCCB) composite score compared with placebo, tested by a one-sided t test. Secondary measures included MCCB domain scores and UCSD Performance-Based Skills Assessment total score, each tested by two-sided t tests. A total of 207 subjects were randomized, of whom 165 (81%) completed the study. ABT-126 showed an improvement that fell short of significance on the MCCB composite score at week 12 (least squares mean difference from placebo, 1.3 and 1.5 for the 10 mg and 25 mg groups, respectively). A significant treatment-by-smoking status interaction was observed on the mean change from baseline to final MCCB composite score: nonsmokers (N=69) demonstrated a difference from placebo of 2.9 (SE=1.4) in the 10 mg group and 5.2 (SE=1.6) in the 25 mg group, whereas no differences were observed in smokers (N=113). Among the nonsmokers in the ABT-126 25 mg group (N=19), significant improvements compared with placebo occurred at final assessment for verbal learning (least squares mean difference=5.5, SE=1.9), working memory (least squares mean difference=5.4, SE=2.0), and attention/vigilance (least squares mean difference=8.7, SE=2.5). The most frequently reported adverse events for ABT-126 were dizziness, diarrhea, and fatigue (all <8% incidence). ABT-126 demonstrated a procognitive effect in nonsmoking subjects, particularly in verbal learning, working memory, and attention.

Organization of the 17th Advanced Accelerator Concepts (AAC16) Workshop by the IEEE. Final Scientific/Technical Report On AWARD NO. DE-SC0015635

Sutter, David F.

The 2016 Workshop on Advanced Accelerator Concepts (AAC) was held at the Gaylord Hotel and Conference Center, National Harbor, Maryland, from July 31 through August 5, 2016. This workshop was the seventeenth in a biennial series that began at Los Alamos National Laboratory in 1982 with a workshop on laser acceleration of particles (see AIP Conf. Proc. 91). AAC16 was organized under the sponsorship of the IEEE Council on Superconductivity with financial support from the U. S. Department of Energy Office of High Energy Physics and the National Science Foundation. The scope of the AAC Workshop has grown since 1982more » to encompass a broad range of topics related to advancing accelerator science and technology beyond its current scientific and technical limits and is now an internationally acknowledged forum for interdisciplinary discussions on advanced accelerator and beam physics/technology concepts covering the widest possible range of applications. The Workshop continued the trend of growing worldwide participation, attracting world wide participation. The Workshop had a total of 256 attendees comprising (including the U.S.) representatives from 11 countries representing 65 different institutions. Each day’s schedule began with plenary sessions covering broad, cross disciplinary interests or general tutorial topics as selected by the Program Committee, followed by a break out into more narrowly focused working groups. The Workshop was organized into eight Working Groups each with a published statement of topical focus, scope of discussion and goals. A summary of the Working Group activities and conclusions is included in the American Institute of Physics’ (AIP) Conference Proceedings now available as an on line open source document. It has been a long tradition of the AAC workshops to encourage strong student participation. This is accomplished in part by subsidizing student attendance, done for this work shop by using funds from the DOE and National Science Foundation to significantly reduce student registration fees. As a result the registered student participation was 75 persons, or 29% of the total attendance of 256 persons, the highest percentage student enrollment the Workshop has ever had. This is the final report for the DOE Office of Science/Office of High Energy Physics grant NO. DE-SC0015635, entitled “Organization of the17th Advanced Accelerator Concepts Workshop by the IEEE.”« less

According to several studies, physicians find sickness certification of patients to be problematic, and some smaller studies suggest that this is a psychosocial work environment problem (WEP). To explore to what extent physicians experience sickness certification as a WEP and the associations of this with the type of clinic and other workplace factors. Analyses of data from a questionnaire sent to all physicians who were living and working in Sweden. The study group consisted of physicians aged <65 years who performed sickness certification tasks (SCTs). Prevalence rates (PR) and 95% confidence intervals (CI) of finding SCTs as a WEP in relation to background factors were calculated. The response rate was 61%. The final study group consisted of 14 210 responders. Half of the physicians (50%) experienced SCTs as a WEP, and 11% found them as a WEP to a great extent. The proportion of physicians experiencing certification tasks as a WEP varied with the type of clinic and were highest in general practice (73%), orthopaedics (68%), rheumatology (67%), neurology (59%) and psychiatry (58%). Using internal medicine as a reference group, the PRs for finding SCTs as a WEP to a great extent were 4.05 (95% CI 3.23-5.09) in general practice, 2.67 (2.05-3.47) in psychiatry and 2.66 (2.04-3.47) in orthopaedics, after adjusting for educational level and frequency of sickness certification consultations. In ear, nose and throat clinics, the PR was 0.43 (0.21-0.88). The findings underline the importance of measures to improve the work situation for physicians regarding sickness certification practices.

Objective Questionnaires for assessment of biomechanical exposure are frequently used in surveillance programs, though few studies have evaluated which key questions are needed. We sought to reduce the number of variables on a surveillance questionnaire by identifying which variables best summarized biomechanical exposure in a survey of the French working population. Methods We used data from the 2002–2003 French experimental network of Upper-limb work-related musculoskeletal disorders (UWMSD), performed on 2685 subjects in which 37 variables assessing biomechanical exposures were available (divided into four ordinal categories, according to the task frequency or duration). Principal Component Analysis (PCA) with orthogonal rotation was performed on these variables. Variables closely associated with factors issued from PCA were retained, except those highly correlated to another variable (rho>0.70). In order to study the relevance of the final list of variables, correlations between a score based on retained variables (PCA score) and the exposure score suggested by the SALTSA group were calculated. The associations between the PCA score and the prevalence of UWMSD were also studied. In a final step, we added back to the list a few variables not retained by PCA, because of their established recognition as risk factors. Results According to the results of the PCA, seven interpretable factors were identified: posture exposures, repetitiveness, handling of heavy loads, distal biomechanical exposures, computer use, forklift operator specific task, and recovery time. Twenty variables strongly correlated with the factors obtained from PCA were retained. The PCA score was strongly correlated both with the SALTSA score and with UWMSD prevalence (p<0.0001). In the final step, six variables were reintegrated. Conclusion Twenty-six variables out of 37 were efficiently selected according to their ability to summarize major biomechanical constraints in a working population, with an approach combining statistical analyses and existing knowledge.

Heyman, Gail D.; Giles, Jessica W.

2010-01-01

SUMMARY When individuals reason in an essentialist way about social categories, they assume that group differences reflect inherently different natures (Gelman, 2003; Rothbart & Taylor, 1992). This paper describes the psychological and social implications of essentialist beliefs, and examines the extent to which children exhibit psychological essentialism when reasoning about gender. The authors discuss reasons young children as well as older children show essentialist reasoning in some contexts, but not in others. Finally, the authors suggest directions for future research, and discuss a primary challenge to many working in this field: reduction of rigid gender beliefs. PMID:21528097

Throughout my HS-STEM internship, I worked on two different projects with a systems analysis group at Sandia National Laboratories in Livermore, California (SNLCA). The first, and primary, project entailed building a conceptual model of health surveillance detection of a bioterror attack. The second project was much smaller in scope and looked at cost tradeoffs between volumetric and surface decontamination after the release of anthrax in a city. Both projects helped me to understand the challenges of planning for a bioterror attack and the importance of preparedness in the public health sector.

Learning ion solid interactions hands-on: An activity based, inquiry oriented, graduate course

NASA Astrophysics Data System (ADS)

Braunstein, Gabriel

2005-12-01

Experimental work, using state of the art instrumentation, is integrated with lectures in a "real life", learning by discovery approach, in the Ion-Solid Interactions graduate/undergraduate course offered by the Department of Physics of the University of Central Florida. The lecture component of the course covers the underlying physical principles, and related scientific and technological applications, associated with the interaction of energetic ions with matter. In the experimental section the students form small groups and perform a variety of projects, experimental and computational, as part of a participative, inquiry oriented, learning process. In the most recent offering of the class, the students deposited a compound semiconductor thin film by dual-gun sputtering deposition, where each group aimed at a different stoichiometry of the same compound (Zn1-xSxOy). Then they analyzed the composition using Rutherford backscattering spectrometry, measured electrical transport properties using Hall effect and conductivity measurements, and determined the band gap using spectrophotometry. Finally the groups shared their results and each wrote a 'journal-like' technical article describing the entire work. In a different assignment, each group also developed a Monte Carlo computer program ('TRIM-like') to simulate the penetration of ions into a solid, in ion implantation, calculating the stopping cross-sections with approximate models, taught in class, which can be analytically solved. The combination of classroom/laboratory activities is very well received by the students. They gain real life experience operating state of the art equipment, and working in teams, while performing research-like projects, and simultaneously they learn the theoretical foundations of the discipline.

In the Multiple Identity Tracking (MIT) task, categorical distinctions between targets and distractors have been found to facilitate tracking (Wei, Zhang, Lyu, & Li in Frontiers in Psychology, 7, 589, 2016). The purpose of this study was to further investigate the reasons for the facilitation effect, through six experiments. The results of Experiments 1-3 excluded the potential explanations of visual distinctiveness, attentional distribution strategy, and a working memory mechanism, respectively. When objects' visual information was preserved and categorical information was removed, the facilitation effect disappeared, suggesting that the visual distinctiveness between targets and distractors was not the main reason for the facilitation effect. Moreover, the facilitation effect was not the result of strategically shifting the attentional distribution, because the targets received more attention than the distractors in all conditions. Additionally, the facilitation effect did not come about because the identities of targets were encoded and stored in visual working memory to assist in the recovery from tracking errors; when working memory was disturbed by the object identities changing during tracking, the facilitation effect still existed. Experiments 4 and 5 showed that observers grouped targets together and segregated them from distractors on the basis of their categorical information. By doing this, observers could largely avoid distractor interference with tracking and improve tracking performance. Finally, Experiment 6 indicated that category-based grouping is not an automatic, but a goal-directed and effortful, strategy. In summary, the present findings show that a semantic category-based target-grouping mechanism exists in the MIT task, which is likely to be the major reason for the tracking facilitation effect.

Development and implementation of an interprofessional consensus-driven process for review and optimization of smart-pump drug libraries and dosing limits are described. The Indianapolis Coalition for Patient Safety (ICPS), which represents 6 Indianapolis-area health systems, identified an opportunity to reduce clinically insignificant alerts that smart infusion pumps present to end users. Through a consensus-driven process, ICPS aimed to identify best practices to implement at individual hospitals in order to establish specific action items for smart-pump drug library optimization. A work group of pharmacists, nurses, and industrial engineers met to evaluate variability within and lack of scrutiny of smart-pump drug libraries. The work group used Lean Six Sigma methodologies to generate a list of key needs and barriers to be addressed in process standardization. The group reviewed targets for smart-pump drug library optimization, including dosing limits, types of alerts reviewed, policies, and safety best practices. The work group also analyzed existing processes at each site to develop a final consensus statement outlining a model process for reviewing alerts and managing smart-pump data. Analysis of the total number of alerts per device across ICPS-affiliated health systems over a 4-year period indicated a 50% decrease (from 7.2 to 3.6 alerts per device per month) after implementation of the model by ICPS member organizations. Through implementation of a standardized, consensus-driven process for smart-pump drug library optimization, ICPS member health systems reduced clinically insignificant smart-pump alerts.

The EGM2008 Global Gravitational Model

NASA Astrophysics Data System (ADS)

Pavlis, N. K.; Holmes, S. A.; Kenyon, S. C.; Factor, J. K.

2008-12-01

The development of a new Earth Gravitational Model (EGM) to degree 2160 has been completed. This model, designated EGM2008, is the product of the final re-iteration of our modelling and estimation approach. Our multi-year effort has produced several Preliminary Gravitational Models (PGM) of increasingly improved performance. One of these models (PGM2007A) was provided for evaluation to an independent Evaluation Working Group, sponsored by the International Association of Geodesy (IAG). In an effort to address certain shortcomings of PGM2007A, we have considered the feedback that we received from this Working Group. As part of this effort, EGM2008 incorporates an improved version of our 5'x5' global gravity anomaly database and has benefited from the latest GRACE based satellite-only solutions (e.g., ITG- GRACE03S). EGM2008 incorporates an improved ocean-wide set of altimetry-derived gravity anomalies that were estimated using PGM2007B (a variant of PGM2007A) and its associated Dynamic Ocean Topography (DOT) model as reference models in a "Remove-Compute-Restore" fashion. For the Least Squares Collocation estimation of our final global 5'x5' area-mean gravity anomaly database, we have used consistently PGM2007B as our reference model to degree 2160. We have developed and used a formulation that predicts area-mean gravity anomalies that are effectively band-limited to degree 2160, thereby minimizing aliasing effects during the harmonic analysis process. We have also placed special emphasis on the refinement and "calibration" of the error estimates that accompany our final combination solution EGM2008. We present the main aspects of the model's development and evaluation. This evaluation was accomplished primarily through the comparison of various model derived quantities with independent data and models (e.g., geoid undulations derived from GPS positioning and spirit levelling, astronomical deflections of the vertical, etc.). We will also present comparisons of our model-implied Dynamic Ocean Topography with other contemporary estimates (e.g., from ECCO).

The aim of the present study was to investigate the personal variability in occupational exposure to NO(2), as a marker of exposure to diesel exhaust, and to compare a statistical method of grouping workers in homogenous groups with a grouping performed by a qualified occupational hygienist. Forty-seven workers exposed to motor exhaust in their occupation were included. Personal measurements of NO(2) were performed with diffusive samplers over three full working shifts. The results from the measurements were analysed with a linear mixed effects model, taking both between and within-worker variability into consideration. The workers were divided into occupational groups in different ways in order to find a categorization, with maximal homogeneity in exposure in each group. We used (B)R(0.95) as an estimator of the between-worker variability. To study the effect of the divisions on the fit of the statistical model, we used the Akaike Information Criterion. The geometric mean for NO(2) for all 47 workers was 69 μg/m(3) and the between-worker variability (B)R(0.95) was 23.8. In six successive steps, the 47 workers were divided into up to eight groups, based on observed job characteristics. In the final grouping, seven groups were included with geometric means ranging from 32 μg/m(3) for outdoor workers, to 316 μg/m(3) for the most exposed group (tunnel construction workers). The (B)R(0.95) varied between 2.4 and 6.3. The within-worker variability (W)R(0.95) for the last division differed in the groups from 2.0 to 7.9. The Akaike Information Criterion decreased from 246, if all persons were included in one group, to 174 for the final grouping. The average level of NO(2) varied about 10 times between the different occupational groups, with the highest level for tunnel construction workers (316 μg/m(3)) and lowest for outdoor workers (32 μg/m(3)). For four of the seven groups the between-worker variability was higher than the within-worker variability. Copyright © 2010 Elsevier GmbH. All rights reserved.

This study aimed at assessing effect of the four dimensions of work-family conflicts (strain and time-based work interference into family and family interference into work) on sleep disturbance in Malaysian working women. This cross-sectional study was conducted among 325 Malaysian married working women. Multiple-stage simple random sampling method was used to recruit women from public service departments of Malaysia. Self-administrated questionnaires were used to measure the study variables and data were analyzed using SPSS version 21. We found that high level of the four dimensions of work-family conflicts significantly increase sleep disturbance. Our analyses also revealed an age-dependent effect of the work-family conflict on sleep disturbance. Women in their 20 to 30 yr old suffer from sleep disturbance due to high level of time-based and strain-based work-interference into family. However, the quality of sleep among women aged 30–39 were affected by strain-based family-interference into work. Finally, women older than 40 yr had significantly disturbed sleep due to strain-based work-interference into family as well as time-based family interference into work. Our findings showed that sleep quality of working women might be disturbed by experiencing high level of work-family conflict. However, the effects of inter-role conflicts on sleep varied among different age groups. PMID:26423332

Reducing cognitive load in the chemistry laboratory by using technology-driven guided inquiry experiments

NASA Astrophysics Data System (ADS)

Hubacz, Frank, Jr.

The chemistry laboratory is an integral component of the learning experience for students enrolled in college-level general chemistry courses. Science education research has shown that guided inquiry investigations provide students with an optimum learning environment within the laboratory. These investigations reflect the basic tenets of constructivism by engaging students in a learning environment that allows them to experience what they learn and to then construct, in their own minds, a meaningful understanding of the ideas and concepts investigated. However, educational research also indicates that the physical plant of the laboratory environment combined with the procedural requirements of the investigation itself often produces a great demand upon a student's working memory. This demand, which is often superfluous to the chemical concept under investigation, creates a sensory overload or extraneous cognitive load within the working memory and becomes a significant obstacle to student learning. Extraneous cognitive load inhibits necessary schema formation within the learner's working memory thereby impeding the transfer of ideas to the learner's long-term memory. Cognitive Load Theory suggests that instructional material developed to reduce extraneous cognitive load leads to an improved learning environment for the student which better allows for schema formation. This study first compared the cognitive load demand, as measured by mental effort, experienced by 33 participants enrolled in a first-year general chemistry course in which the treatment group, using technology based investigations, and the non-treatment group, using traditional labware, investigated identical chemical concepts on five different exercises. Mental effort was measured via a mental effort survey, a statistical comparison of individual survey results to a procedural step count, and an analysis of fourteen post-treatment interviews. Next, a statistical analysis of achievement was completed by comparing lab grade averages, final exam averages, and final course grade averages between the two groups. Participant mental effort survey results showed significant positive effects of technology in reducing cognitive load for two laboratory investigations. One investigation revealed a significant difference in achievement measured by lab grade average comparisons. Although results of this study are inconclusive as to the usefulness of technology-driven investigations to affect learning, recommendations for further study are discussed.

Establishing Final Cleanup Decisions for the Hanford Site River Corridor

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

Lerch, J.A.; Sands, J.P.

2007-07-01

A major challenge in the River Corridor Closure Contract is establishing final cleanup decisions for the source operable units in the Hanford Site river corridor. Cleanup actions in the river corridor began in 1994 and have been performed in accordance with a 'bias for action' approach adopted by the Tri-Parties - the U.S. Department of Energy, U.S. Environmental Protection Agency, and Washington State Department of Ecology. This approach enabled early application of cleanup dollars on actual remediation of contaminated waste sites. Consequently, the regulatory framework authorizing cleanup actions at source operable units in the river corridor consists largely of interimmore » action records of decision, which were supported by qualitative risk assessments. Obtaining final cleanup decisions for the source operable units is necessary to determine whether past cleanup actions in the river corridor are protective of human health and the environment and to identify any course corrections that may be needed to ensure that ongoing and future cleanup actions are protective. Because the cleanup actions are ongoing, it is desirable to establish the final cleanup decisions as early as possible to minimize the impacts of any identified course corrections to the present cleanup approach. Development of a strategy to obtain final cleanup decisions for the source operable units in a manner that is responsive to desires for an integrated approach with the groundwater and Columbia River components while maintaining the ability to evaluate each component on its own merit represents a significant challenge. There are many different options for grouping final cleanup decisions, and each involved party or stakeholder brings slightly different interests that shape the approach. Regardless of the selected approach, there are several specific challenges and issues to be addressed before making final cleanup decisions. A multi-agency and contractor working group has been established to address these issues and develop an endorsed strategy. Ultimately, it is anticipated that the Tri-Parties will establish a set of milestones to document pathway selection and define schedule requirements. (authors)« less

Fifty-six bovine incisor roots were endodontically prepared and separated into 7 groups (n = 8) according to irrigation protocols: group 1, sterile saline (control); group 2, chlorhexidine (CHX) gel 2% and saline; group 3, sodium hypochlorite (NaOCl) 5.25% and saline; group 4, CHX and saline (final irrigation with ethylenediaminetetraacetic acid [EDTA] 17%); group 5, NaOCl and saline (final irrigation with EDTA); group 6, CHX and saline (final irrigation with NaOCl and EDTA); and group 7, NaOCl (final irrigation with CHX and EDTA). No statistically significant difference was found among the groups. Within the limitations of this study, it can be concluded that the different irrigation protocols did not influence the bond strength of self-adhesive resin cement, which presented similar behaviors at the 3 root depths studied.

It has been claimed that working memory training programs produce diverse beneficial effects. This article presents a meta-analysis of working memory training studies (with a pretest-posttest design and a control group) that have examined transfer to other measures (nonverbal ability, verbal ability, word decoding, reading comprehension, or arithmetic; 87 publications with 145 experimental comparisons). Immediately following training there were reliable improvements on measures of intermediate transfer (verbal and visuospatial working memory). For measures of far transfer (nonverbal ability, verbal ability, word decoding, reading comprehension, arithmetic) there was no convincing evidence of any reliable improvements when working memory training was compared with a treated control condition. Furthermore, mediation analyses indicated that across studies, the degree of improvement on working memory measures was not related to the magnitude of far-transfer effects found. Finally, analysis of publication bias shows that there is no evidential value from the studies of working memory training using treated controls. The authors conclude that working memory training programs appear to produce short-term, specific training effects that do not generalize to measures of “real-world” cognitive skills. These results seriously question the practical and theoretical importance of current computerized working memory programs as methods of training working memory skills. PMID:27474138

The current study evaluated the costs and benefits of a simple aerobic walking program for patients with chronic obstructive pulmonary disease (COPD). This was a blinded randomized controlled clinical trial that recruited 72 patients diagnosed with COPD, 40 of whom were included in the study and divided into two groups [control group (CG) and pulmonary rehabilitation group (GPR)]. We assessed pulmonary function, distance covered during the 6-minute walk test (6MWT), respiratory and peripheral muscle strength, health-related quality of life (HRQOL), body composition, and level of activities of daily living (ADLs) before and after an 8-week walking program. The financial costs were calculated according to the pricing table of the Brazilian Unified Health System (SUS). Only 34 of the 40 patients remained in the final sample; 16 in the CG and 18 in the GPR (FEV1: 50.9 ± 14% predicted and FEV1: 56 ± 0.5% predicted, respectively). The intervention group exhibited improvements in the 6MWT, sensation of dyspnea and fatigue, work performed, BODE index (p<0.01), HRQOL, ADL level (p<0.001), and lower limb strength (p<0.05). The final mean cost per patient for the GPR was R$ 148.75 (~US$ 75.00) and no patient significantly exceeded this value. However, 2 patients in the CG did exceed this value, incurring a cost of R$ 689.15 (~US$ 345.00). Aerobic walking demonstrated significant clinical benefits in a cost-efficient manner in patients with COPD.

The KDIGO (Kidney Disease: Improving Global Outcomes) 2012 clinical practice guideline for the management of blood pressure (BP) in chronic kidney disease (CKD) provides the structural and evidence base for the Canadian Society of Nephrology (CSN) commentary on this guideline's relevancy and application to the Canadian health care system. While in general agreement, we provide commentary on 13 of the 21 KDIGO guideline statements. Specifically, we agreed that nonpharmacological interventions should play a significant role in the management of hypertension in patients with CKD. We also agreed that the approach to the management of hypertension in elderly patients with CKD should be individualized and take into account comorbid conditions to avoid adverse outcomes from excessive BP lowering. In contrast to KDIGO, the CSN Work Group believes there is insufficient evidence to target a lower BP for nondiabetic CKD patients based on the presence and severity of albuminuria. The CSN Work Group concurs with the Canadian Hypertension Education Program (CHEP) recommendation of a target BP for all non-dialysis-dependent CKD patients without diabetes of ≤140 mm Hg systolic and ≤90 mm Hg diastolic. Similarly, it is our position that in diabetic patients with CKD and normal urinary albumin excretion, raising the threshold for treatment from <130 mm Hg systolic BP to <140 mm Hg systolic BP could increase stroke risk and the risk of worsening kidney disease. The CSN Work Group concurs with the CHEP and the Canadian Diabetic Association recommendation for diabetic patients with CKD with or without albuminuria to continue to be treated to a BP target similar to that of the overall diabetes population, aiming for BP levels < 130/80 mm Hg. Consistent with this, the CSN Work Group endorses a BP target of <130/80 mm Hg for diabetic patients with a kidney transplant. Finally, in the absence of evidence for a lower BP target, the CSN Work Group concurs with the CHEP recommendation to target BP<140/90 mm Hg for nondiabetic patients with a kidney transplant.

Becker's theory of taste-based discrimination predicts that relative employment of the discriminated social group will improve if there is a decrease in the level of prejudice for the marginally discriminating employer. In this paper we experimentally test this prediction offered by Garry Becker in his seminal work on taste based discrimination, in the context of caste in India, with management students (potential employers in the near future) as subjects. First, we measure caste prejudice and show that awareness through a TV social program reduces implicit prejudice against the lower caste and the reduction is sustained over time. Second, we find that the treatment reduces the prejudice levels of those in the left tail of the prejudice distribution - the group which can potentially affect real outcomes as predicted by the theory. And finally, a larger share of the treatment group subjects exhibit favorable opinion about reservation in jobs for the lower caste. PMID:25902290

Signaling, Regulation, and Specificity of the Type II p21-activated Kinases.

The p21-activated kinases (PAKs) are a family of six serine/threonine kinases that act as key effectors of RHO family GTPases in mammalian cells. PAKs are subdivided into two groups: type I PAKs (PAK1, PAK2, and PAK3) and type II PAKs (PAK4, PAK5, and PAK6). Although these groups are involved in common signaling pathways, recent work indicates that the two groups have distinct modes of regulation and have both unique and common substrates. Here, we review recent insights into the molecular level details that govern regulation of type II PAK signaling. We also consider mechanisms by which signal transduction is regulated at the level of substrate specificity. Finally, we discuss the implications of these studies for clinical targeting of these kinases. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

The results of a survey sent to practice leaders in the ACR Practice of Radiology Environment Database show that the majority of responding groups will continue to hire recently trained residents and fellows even though they have been unable to take the final ABR diagnostic radiology certifying examination. However, a significant minority of private practice groups will not hire these individuals. The majority of private practices expect the timing change for the ABR certifying examinations to affect their groups' function. In contrast, the majority of academic medical school practices expect little or no impact. Residents and fellows should not expect work time off or protected time to study for the certifying examination or for their maintenance of certification examinations in the future.

This article presents a discussion of key issues for the education of nurses, midwives and health visitors following the completion of a Department of Health funded project, managed by the General Social Care Council and conducted jointly by two research centres; Salford Centre for Social Work Research and Salford Centre for Nursing, Midwifery and Collaborative Research. The work was initiated in response to Lord Laming's report on the circumstances leading to the death of Victoria Climbié. The project was conducted in relation to specified professions and occupational groups: doctors; health visitors; midwives; nurses; police; teachers, and social workers. It was undertaken in two stages. The first stage mapped existing material about standards in relation to education and training for interagency working. The second stage engaged in an extensive consultation exercise through which a model and a set of proposed standards for interagency education and training for interagency work were developed. The former is detailed fully in this report, while nine examples of standards are presented. The project final report was presented seven months after commencement.

This technical note describes some Bayesian procedures for the analysis of group studies that use nonlinear models at the first (within-subject) level – e.g., dynamic causal models – and linear models at subsequent (between-subject) levels. Its focus is on using Bayesian model reduction to finesse the inversion of multiple models of a single dataset or a single (hierarchical or empirical Bayes) model of multiple datasets. These applications of Bayesian model reduction allow one to consider parametric random effects and make inferences about group effects very efficiently (in a few seconds). We provide the relatively straightforward theoretical background to these procedures and illustrate their application using a worked example. This example uses a simulated mismatch negativity study of schizophrenia. We illustrate the robustness of Bayesian model reduction to violations of the (commonly used) Laplace assumption in dynamic causal modelling and show how its recursive application can facilitate both classical and Bayesian inference about group differences. Finally, we consider the application of these empirical Bayesian procedures to classification and prediction. PMID:26569570

Summary In October 2010, a group of experts met as part of the transatlantic think tank for toxicology (t4) to exchange ideas about the current status and future of safety testing of nanomaterials. At present, there is no widely accepted path forward to assure appropriate and effective hazard identification for engineered nanomaterials. The group discussed needs for characterization of nanomaterials and identified testing protocols that incorporate the use of innovative alternative whole models such as zebrafish or C. elegans, as well as in vitro or alternative methods to examine specific functional pathways and modes of action. The group proposed elements of a potential testing scheme for nanomaterials that works towards an integrated testing strategy, incorporating the goals of the NRC report Toxicity Testing in the 21st Century: A Vision and a Strategy by focusing on pathways of toxic response, and utilizing an evidence-based strategy for developing the knowledge base for safety assessment. Finally, the group recommended that a reliable, open, curated database be developed that interfaces with existing databases to enable sharing of information. PMID:21993959

The aim of this study was to evaluate in scientific literature the more frequent work injuries among the occupational categories examined (construction workers, healthcare workers, night workers and shift work, drivers) and to identify occupational stressors that increase the risk of injury. The research was conducted through review of the scientific literature between 1990 and 2014. Two hundred articles were found of which 42 selected in the following categories: construction workers, healthcare workers, shift workers, lorry drivers. The movement of machinery and working at height are due to injury for building sector and they were positively correlated with physical (r = 0,206) and mental (r = 0,254) stress. In health workers the injuries are more frequently bruises and sprains (50%). Studies showed a higher rate of injury in a group of shift workers compared to a control group on a rota basis (p <0.0001). Road accidents for drivers represent the most frequent cause of injury of which 13% comes from falling asleep, while 31% from distractions (OR = 3.16; CI = 1:22 to 8:24). Nurses have frequent injuries due to bruises, lumbago, punctures with needles and surgical wounds. Construction workers often suffer serious injury derived from falls at height, handling machinery. For workers on a rota basis, injuries are often related to lack of sleep. Road accidents in drivers are the most common injuries. A synergistic action finalized to promote health and safety organization, to ensure a work environment more secure, is advisable.

Increased delivery stride length places greater loads on the ankle joint in elite male cricket fast bowlers.

Spratford, Wayne; Hicks, Amy

2014-01-01

The purpose of this study was to investigate the effect stride length has on ankle biomechanics of the leading leg with reference to the potential risk of injury in cricket fast bowlers. Ankle joint kinematic and kinetic data were collected from 51 male fast bowlers during the stance phase of the final delivery stride. The bowling cohort comprised national under-19, first class and international-level athletes. Bowlers were placed into either Short, Average or Long groups based on final stride length, allowing statistical differences to be measured. A multivariate analysis of variance with a Bonferroni post-hoc correction (α = 0.05) revealed significant differences between peak plantarflexion angles (Short-Long P = 0.005, Average and Long P = 0.04) and negative joint work (Average-Long P = 0.026). This study highlighted that during fast bowling the ankle joint of the leading leg experiences high forces under wide ranges of movement. As stride length increases, greater amounts of negative work and plantarflexion are experienced. These increases place greater loads on the ankle joint and move the foot into positions that make it more susceptible to injuries such as posterior impingement syndrome.

The present study evaluated the stability of math learning difficulties over a 2-year period and investigated several factors that might influence this stability (categorical vs. continuous change, liberal vs. conservative cut point, broad vs. specific math assessment); the prediction of math performance over time and by performance level was also evaluated. Participants were 144 students initially identified as having a math difficulty (MD) or no learning difficulty according to low achievement criteria in the spring of Grade 3 or Grade 4. Students were reassessed 2 years later. For both measure types, a similar proportion of students changed whether assessed categorically or continuously. However, categorical change was heavily dependent on distance from the cut point and so more common for MD, who started closer to the cut point; reliable change index change was more similar across groups. There were few differences with regard to severity level of MD on continuous metrics or in terms of prediction. Final math performance on a broad computation measure was predicted by behavioral inattention and working memory while considering initial performance; for a specific fluency measure, working memory was not uniquely related, and behavioral inattention more variably related to final performance, again while considering initial performance.

Developing new technologies like nano-technology improves the performance of the energy industries. Consequently, emerging new groups of thermal cycles in nano-scale can revolutionize the energy systems' future. This paper presents a thermo-dynamical study of a nano-scale irreversible Stirling engine cycle with the aim of optimizing the performance of the Stirling engine cycle. In the Stirling engine cycle the working fluid is an Ideal Maxwell-Boltzmann gas. Moreover, two different strategies are proposed for a multi-objective optimization issue, and the outcomes of each strategy are evaluated separately. The first strategy is proposed to maximize the ecological coefficient of performance (ECOP), the dimensionless ecological function (ecf) and the dimensionless thermo-economic objective function ( F . Furthermore, the second strategy is suggested to maximize the thermal efficiency ( η), the dimensionless ecological function (ecf) and the dimensionless thermo-economic objective function ( F). All the strategies in the present work are executed via a multi-objective evolutionary algorithms based on NSGA∥ method. Finally, to achieve the final answer in each strategy, three well-known decision makers are executed. Lastly, deviations of the outcomes gained in each strategy and each decision maker are evaluated separately.

Previous studies of the safety and environmental aspects of the SOMBRERO inertial fusion energy (IFE) power plant design did not completely address the issues associated with the final focus system. While past work calculated neutron fluences for a grazing incidence metal mirror (GIMM) and a final focus mirror, scattering off of the final optical component was not included, and thus, fluences in the final focus mirror were significantly underestimated. In addition, past work did not consider neutron-induced gamma-rays. Finally, power plant lifetime waste volumes may have been underestimated as neutron activation of the neutron dumps and building structure were notmore » addressed. In the present work, a modified version of the SOMBRERO target building is presented where a significantly larger open solid-angle fraction (5%) is used to enhance beam smoothing of a diode-pumped solid-state laser (DPSSL). The GIMMs are replaced with transmissive fused silica wedges and have been included in three -dimensional neutron and photon transport calculations. This work shows that a power plant with a large open solid-angle fraction, needed for beam smoothing with a DPSSL, is acceptable from tritium breeding, and neutron activation points-of-view.« less

Endocrine and mood responses to two working days in female teachers.

Currently, a considerable amount of work stress is present in school teachers, one of the occupational groups with the highest levels of job strain and burnout. As chronic stress produces significant modifications in emotional adjustment and neuroendocrine functioning, we aimed to investigate the role of these work stress constructs in the endocrine and mood responses of a group of female teachers during two working days (WD) at different moments in the academic year. We studied mood as well as levels of cortisol and testosterone, representative of a predominant catabolic or anabolic balance. Our results showed that higher "control" was associated with higher positive mood (p = .028 on WD1 and p = .057 on WD2) and salivary testosterone (Tsal) (p = .022 on WD1), whereas "demands" and "total job strain" were related to negative mood (p = .011 and p = .015, respectively). Participants with higher scores on "total burnout" and "emotional exhaustion" also had higher negative mood (p < .05 in all cases). Depersonalization correlated positively with negative mood (p = .019 and p = .006 on WD1 and WD2, respectively). Finally, personal accomplishment showed an inverse relationship with negative mood (p = .038 on WD2). These results are useful for job risk prevention and interventions that should focus on the control dimension of the job strain questionnaire and on personal accomplishment from the burnout scale.

Advancing Community–Based Research with Urban American Indian Populations: Multidisciplinary Perspectives

The U.S. has witnessed significant growth among urban AI populations in recent decades, and concerns have been raised that these populations face equal or greater degrees of disadvantage than their reservation counterparts. Surprisingly little urban AI research or community work has been documented in the literature, and even less has been written about the influences of urban settings on community-based work with these populations. Given the deep commitments of community psychology to empowering disadvantaged groups and understanding the impact of contextual factors on the lives of individuals and groups, community psychologists are well suited to fill these gaps in the literature. Toward informing such efforts, this work offers multidisciplinary insights from distinct idiographic accounts of community-based behavioral health research with urban AI populations. Accounts are offered by three researchers and one urban AI community organization staff member, and particular attention is given to issues of community heterogeneity, geography, membership, and collaboration. Each first-person account provides “lessons learned” from the urban context in which the research occurred. Together, these accounts suggest several important areas of consideration in research with urban AIs, some of which also seem relevant to reservation-based work. Finally, the potential role of research as a tool of empowerment for urban AI populations is emphasized, suggesting future research attend to the intersections of identity, sense of community, and empowerment in urban AI populations.

This study adapted ecological momentary assessment methods to: (a) examine differences in work stress between nurses and physicians, and (b) to study relationships between work stress, work activity patterns, and sleep. A total of 185 physicians and 119 nurses (206 women, 98 men) working in four teaching hospitals participated in an observational study of work stress. Participants carried handheld computers that randomly prompted them for work activity, patient load, and work stress information. Participants completed more than 9,500 random interval surveys during the study (an average of 30.8 surveys per person-week). Approximately 85% of all surveys were completed in full (73.3%) or partially (11.6%). Emotional stress scores among physicians were nearly 50% higher (26.9[19.0]) than those of nurses (18.1[14.9], r[302] = .37, p < .001). Direct and indirect care activities were associated with higher stress reports by both clinician groups (rs[159] = .14-.26, ps < .01). Sleep quality and quantity were predictors of work stress scores (ps < .05). Finally, higher work stress and lower sleep quality were also associated with poorer memory performance (r[302] = -.12, .17, ps < 05). The findings identify patterns of work stress in relationship to work activities, sleep habits, and provider differences that may be used to assist ongoing hospital work reform efforts.

Protection of working mothers: operational guide document. The aim of this operational guide document is to protect the health of working mothers and their babies during pregnancy, puerperium and breastfeeding. The project was developed by a technical working group which included professionals in the pertinent fields from the Workplace Prevention and Safety Services of the local Vasta-2 Area of the Marche Regional Health Service:physicians, health assistants, and nurses. It is considered to be a useful tool for risk assessment at the workplace aimed at professionals who are involved, with various duties and responsibilities, in the health care of the working mother. This paper consists of two functionally related sections, "Table of risks" and "Technical specifications". In the "Table of Risks" section, the occupational hazards for women during pregnancy or postpartum were analyzed with the highest possible degree of care. To this end the technical group provided, for each occupational hazard, its own operational suggestions, in relation to legislation, current scientific knowledge and Guidelines of other Italian Regions. The Marche Regional Section of the Italian Society of Occupational Health and Industrial Hygiene (SIMLII) participated in the final draft of the entire document. The second section, "Technical Specifications", illustrates the main tasks and any risks involved in the 34 manufacturing sectors most prevalent in this area. This operational guide document is intended to be the beginning of a common strategy in public health to achieve a wider field of action in promotion and information aimed at protecting the reproductive health of working mothers.

Purpose Physicians are often ill-equipped for the leadership activities their work demands. In part, this is due to a gap in traditional medical education. An emergent international network is developing a globally relevant leadership curriculum for postgraduate medical education. The purpose of this article is to share key learnings from this process to date. Design/methodology/approach The Toronto International Summit on Leadership Education for Physicians (TISLEP) was hosted by the Royal College of Physicians and Surgeons of Canada, and the University of Toronto's Faculty of Medicine and Institute of Health Policy, Management and Evaluation. Of 64 attendees from eight countries, 34 joined working groups to develop leadership competencies. The CanMEDS Competency Framework, stage of learner development and venue of learning formed the scaffold for the work. Emotional intelligence was selected as the topic to test the feasibility of fruitful international collaboration; results were presented at TISLEP 2015. Findings Dedicated international stakeholders engaged actively and constructively through defined working groups to develop a globally relevant, competency-based curriculum for physician leadership education. Eleven principles are recommended for consideration in physician leadership curriculum development. Defining common language and taxonomy is essential for a harmonized product.

Originality/value International stakeholders are collaborating successfully on a graduated, competency-based leadership curriculum for postgraduate medical learners. The final product will be available for adaptation to local needs. An international physician leadership education network is being developed to support and expand the work underway.

Astronomical Activities with Disabled People

NASA Astrophysics Data System (ADS)

Gil, Amelia Ortiz

With this contribution we would like to share our experiences in organizing astronomical activities addressed to people with disabilities. The goal is twofold: we would like to invite all those with similar experiences to contribute to the compilation of a document to guide other astronomers who might be interested in carrying out these kind of activities aimed at groups of people with special needs. We also want to persuade public outreach officers that working with disabled people is not as difficult as it may seem at first, as long as they are provided with adequate educational material and guidelines about how to do it. The final goal is to build a repository that can be used by educators and public outreach officers as a guide when working with disabled people, specially during the International Year of Astronomy.

The direction of object enumeration reflects children's enculturation but previous work on the development of such spatial preferences has been inconsistent. Therefore, we documented directional preferences in finger counting, object counting, and picture naming for children (4 groups from 3 to 6 years, N = 104) and adults (N = 56). We found a right-side preference for finger counting in 3- to 6-year-olds and a left-side preference for counting objects and naming pictures by 6 years of age. Children were consistent in their special preferences when comparing object counting and picture naming, but not in other task pairings. Finally, spatial preferences were not related to cardinality comprehension. These results, together with other recent work, suggest a gradual development of spatial-numerical associations from early non-directional mappings into culturally constrained directional mappings.

Policy initiatives to improve retention of the rural health workforce have relied primarily on evidence for rural doctors, most of whom practice under a private business model. Much of the literature for rural allied health (AH) workforce focuses on the public sector. The AH professions are diverse, with mixed public, private or combined practice settings. This study explores sector differences in factors affecting retention of rural AH professionals. This study compared respondents from the 2008 Rural Allied Health Workforce (RAHW) survey recruiting all AH professionals in rural New South Wales. Comparisons between public (n = 833) and private (n = 756) groups were undertaken using Chi square analysis to measure association for demographics, job satisfaction and intention to leave. The final section of the RAHW survey comprised 33 questions relating to retention. A factor analysis was conducted for each cohort. Factor reliability was assessed and retained factors were included in a binary logistic regression analysis for each cohort predicting intention to leave. Six factors were identified: professional isolation, participation in community, clinical demand, taking time away from work, resources and 'specialist generalist' work. Factors differed slightly between groups. A seventh factor (management) was present only in the public cohort. Gender was not a significant predictor of intention to leave. Age group was the strongest predictor of intention to leave with younger and older groups being significantly more likely to leave than middle aged.In univariate logistic analysis (after adjusting for age group), the ability to get away from work did not predict intention to leave in either group. In multivariate analysis, high clinical demand predicted intention to leave in both the public (OR = 1.40, 95% CI = 1.08, 1.83) and private (OR = 1.61, 95% CI = 1.15, 2.25) cohorts. Professional isolation (OR = 1.39. 95% CI = 1.11, 1.75) and Participation in community (OR = 1.57, 95% CI = 1.13, 2.19) also contributed to the model in the public cohort. This paper demonstrates differences between those working in public versus private sectors and suggests that effectiveness of policy initiatives may be improved through better targeting.

Minimal hepatic encephalopathy (mHE) has been shown to affect daily functioning, quality of life, driving and overall mortality. However, little is known about treating or diagnosing early impairments in mHE. We studied one of its precipitating factors, portal hypertension which is driving the inflammatory process behind mHE. The purpose was to describe an indirect diagnostic method able to detect the pathology at early stages based on the study of the vascularization and mast cells conjunctival hyperplasia as secondary inflammatory response associated to portal hypertension. Finally, we correlated the presence of histological changes in the eye in mHE with deficits in behavioral task acquisition. Rats were trained on a stimulus-response task and a spatial working memory task using the Morris water maze. Two groups of animals were used: a SHAM (sham-operated) group (n=10) and a portal hypertension (HT) group (n=10). The triple portal vein ligation method was used to create an animal model of mHE. Latencies to reach the platform, number of glial fibrillary acidic protein-immunoreactive astrocytes (GFAP-IR), mast cell expression and presence/absence of blood and lymphatic vessels were examined. There were differences in stimulus-response behavioral performance, with a deficit in the acquisition in the HT group. However, no differences between groups were found on the spatial working memory task. At the same time, differences between groups were found in the GFAP-IR density, which was lower in the HT group, and in the number of mast cells and the presence of vessels, which were higher in the HT group. In this study, we provide the first preliminary insight into the validity of exploring the eye as a possible tool to assess the diagnosis of mHE conditions. Copyright © 2017 Elsevier Inc.

Porcelain veneers have become an interesting treatment option to correct the shape and color of anterior teeth. Because of their limited thickness and high translucency, achieving a good color match is influenced by several variables. The aim of this work was to investigate the influence of natural dentin and resin cement colors on final color match of porcelain veneers. A preselected shade tab (A1) was chosen as the target color for a maxillary central incisor, and its color parameters (L*a*b*) were measured using a digital spectrophotometer (SpectroShade, MHT). Nine natural dentin colors (Natural Die Material, Ivoclar Vivadent) representing a wide range of tooth colors were used to prepare resin replicas of the maxillary central incisor with a standard preparation for porcelain veneers. The prepared porcelain veneers (IPS Empress Esthetic, A1, 0.6 mm thick, Ivoclar Vivadent) were cemented on the resin dies (nine groups of natural dentin colors) using seven shades of resin cement (Variolink Veneers, Ivoclar Vivadent). The L*a*b* values of the cemented veneers were measured, and DE values were calculated against the preselected target color (A1). DE greater than 3.3 was considered as a significant color mismatch detectable by the human eye. The seven shades of resin cement had no significant influence on the final color of the veneers, as the measured DE values were almost identical for every test group. On the other hand, the color of natural dentin was a significant factor that influenced final color match. None of the 63 tested combinations (nine natural dentin colors and seven resin cement colors) produced an acceptable color match. Thin porcelain veneers cannot mask underlying tooth color even when different shades of resin cement are used. Incorporation of opaque porcelain (high chroma) may improve final color match.

Catalytic conversion of light alkanes. Final report, January 1, 1990--October 31, 1994

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

NONE

During the course of the first three years of the Cooperative Agreement (Phase I-III), we uncovered a family of metal perhaloporphyrin complexes which had unprecedented activity for the selective air-oxidation of fight alkanes to alcohols. The reactivity of fight hydrocarbon substrates with air or oxygen was in the order: isobutane>propane>ethane>methane, in accord with their homolytic bond dissociation energies. Isobutane was so reactive that the proof-of concept stage of a process for producing tert-butyl alcohol from isobutane was begun (Phase V). It was proposed that as more active catalytic systems were developed (Phases IV, VI), propane, then ethane and finally methanemore » oxidations will move into this stage (Phases VII through IX). As of this writing, however, the program has been terminated during the later stages of Phases V and VI so that further work is not anticipated. We made excellent progress during 1994 in generating a class of less costly new materials which have the potential for high catalytic activity. New routes were developed for replacing costly perfluorophenyl groups in the meso-position of metalloporphyrin catalysts with far less expensive and lower molecular weight perfluoromethyl groups.« less

Identification of pesticide exposure determinants has become an issue in explaining exposure variability and improving control measures. Most studies have been conducted in industrialized countries. The aim of this study was to identify relevant dermal exposure determinants among Nicaraguan subsistence farmers. Field data on possible determinants were collected during 32 pesticide applications through observation and supplementary videorecording. A multistep reduction strategy brought down the 110 potential exposure determinants to 27 variables, which were grouped as worksite, spray equipment, working practices, clothing or hygiene practices related. Dermal exposure was quantified with a modification of Fenske's visual scoring method. Multivariate linear regression modeling within groups and across groups was performed. In the within-group analyses, work practices, spray equipment and worksite related determinants explained 52, 33 and 25% of the exposure variability, respectively. Clothing and hygiene practices were weaker determinants and did not always reduce the exposure. The final model included determinants from all groups except hygiene practices and explained 69% of the exposure variability. A less restricted model increased the explained variability to 75%. Several novel determinants were identified, including spraying on a muddy terrain, dew on plants, sealing the tank lid with a cloth and wiping sweat from the face. This study showed that a combination of observation and visual scoring techniques can provide valuable information on determinants of pesticide exposure and affected body parts under developing country conditions. The results could be used to develop job-specific questionnaires and to design training and preventive programs.
