A swallowtail catastrophe model for the emergence of leadership in coordination-intensive groups.

PubMed

Guastello, Stephen J; Bond, Robert W

2007-04-01

This research extended the previous studies concerning the swallowtail catastrophe model for leadership emergence to coordination-intensive groups. Thirteen 4-person groups composed of undergraduates played in Intersection coordination (card game) task and were allowed to talk while performing it; 13 other groups worked nonverbally. A questionnaire measured leadership emergence at the end of the game along with other social contributions to the groups' efforts. The swallowtail catastrophe model that was evident in previous leadership emergence phenomena in creative problem solving and production groups was found here also. All three control parameters were identified: a general participation variable that was akin to K in the rugged landscape model of self-organization, task control, and whether the groups worked verbally or nonverbally. Several new avenues for future research were delineated.

2017-12-01

The Arctic Council is an intergovernmental forum promoting cooperation, coordination and interaction among the Arctic States and indigenous communities on issues of sustainable development and environmental protection in the North. The work of the Council is primarily carried out by six Working Groups: Arctic Contaminants Action Program, Arctic Monitoring and Assessment Programme, Conservation of Arctic Flora and Fauna, Emergency Prevention, Preparedness and Response, Protection of the Arctic Marine Environment, and Sustainable Development Working Group. The Working Groups are composed of researchers and representatives from government agencies. Each Working Group issues numerous scientific assessments and reports on a broad field of subjects, from climate change to emergency response in the Arctic. A key goal of these publications is to contribute to policy-making in the Arctic. Complex networks of information systems and the connections between the diverse elements within the systems have been identified via network analysis. This allowed to distinguish data sources that were used in the composition of the primary publications of the Working Groups. Next step is to implement network analysis to identify and map the relationships between the Working Groups and policy makers in the Arctic.

Educational Effects of Practical Education Using a Debate Exercise on Engineering Ethics

NASA Astrophysics Data System (ADS)

Takanokura, Masato; Hayashi, Shigeo

The educational effects of practical education using a debate exercise are investigated using questionnaires. For the group-work composed of discussion and debate, students understand thoroughly various engineering ethical topics, such as factors preventing ethical decision-making. Students enhance their abilities to make a rational and logical decision by themselves such as a judgment based on correct information. Mutual evaluation by students through group interaction elevates positive educational effects. However, students answer fewer questions related to the understanding of professional duties and cooperate social responsibility because of the group-work using failure cases. Students also show less progress in their abilities to communicate with others and to express their opinions to audiences. A more suitable number of group members solves the latter problem.

In this talk we present the aims, goals and activities that have been started by the working group on Astronomy for Equity and Inclusion. This working group is part of Commission 1 ''Astronomy Education and Development'' of Division C ''Education, Outreach and Heritage'' of the International Astronomical Union (IAU). The working group was born with the aim of developing new strategies and resources to promote the access to Astronomy, both at the profesional and outreach levels, for persons with special needs or for those who could be excluded because of race or sexual orientation (among other reasons). It is composed of astronomers affiliated with the IAU and other volunteers who work in astronomy, education and special needs, as well as partner organizations like the IAU Office of Astronomy for Development (OAD), Astronomers without Borders (AWB), the Galileo Teacher Training Program (GTTP) or Universe Awareness (UNAWE). To reach those goals we have started different initiatives which are outlined at the working group’s website, like a repository of resources or the creation of a document about good practices, and the establishment of a tight collaboration with the Working Group about Accessibility of the American Astronomical Society, which was formed recently too.

2013-12-15

Functional recovery, including return to work, in Bipolar Disorder (BD) lags behind clinical recovery and may be incomplete when acute mood symptoms have subsided. We examined impact of cognition on work status and underemployment in a sample of 156 Euthymic-BD and 143 controls (HC) who were divided into working/not working groups. Clinical, health, social support, and personality data were collected, and eight cognitive factors were derived from a battery of neuropsychological tests. The HC groups outperformed the BD groups on seven of eight cognitive factors. The working-BD group outperformed the not working-BD group on 4 cognitive factors composed of tasks of emotion processing and executive functioning including processing speed and set shifting. Emotion processing and executive tasks were predictive of BD unemployment, after accounting for number of mood episodes. Four cognitive factors accounted for a significant amount of the variance in work status among the BD participants. Results indicate that patients with BD who are unemployed/unable to work exhibit greater difficulties processing emotional information and on executive tasks that comprise a set shifting or interference resolution component as compared to those who are employed, independent of other factors. These cognitive and affective factors are suggested as targets for treatment and/or accommodations. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

The centers of psychosocial care (CAPS, acronym in Portuguese) are strategic devices for mental health care currently available in Brazil. Nurses are professionals required to compose the minimum staff of this device, which values the group activities involving users. This study presents a report of the experience of nursing undergraduates from Universidade Federal do Mato Grosso (UFMT) on their conducting waiting-room group sessions with relatives of users of a CAPS from Cuiabá, Mato Grosso state. This experience is justified by the fact that nursing students have few opportunities to develop group approach abilities during their graduation course, which focuses mainly on clinical individual care. The aim of the experience was to provide theoretical-practical learning of all the work stages of group work: recognizing the need and possibility of conducting the activity, planning, coordination and group evaluation. The results confirm the need and possibility of performing group experiences in mental health care and in nursing education.

Naldemedine versus placebo for opioid-induced constipation (COMPOSE-1 and COMPOSE-2): two multicentre, phase 3, double-blind, randomised, parallel-group trials.

Opioid-induced constipation is a frequent side-effect of opioid treatment, and standard interventions have limited or inconsistent efficacy. This study assessed the efficacy and safety of naldemedine, a peripherally acting μ-opioid receptor antagonist, for the treatment of opioid-induced constipation in patients with chronic non-cancer pain. We report two double-blind, randomised, placebo-controlled trials in adults with chronic non-cancer pain and opioid-induced constipation. The first (COMPOSE-1) was done in 68 outpatient sites in seven countries and the second (COMPOSE-2) at 69 outpatient sites in six countries; both studies were done in Europe and the USA. Eligible patients were aged 18-80 years, did not use laxatives, and had a stable opioid regimen for treatment of chronic non-cancer pain with a total daily dose averaging at least 30 mg (morphine equivalent) for at least 1 month before screening. Patients were randomly assigned (1:1) to receive either oral naldemedine 0·2 mg or matching placebo once a day for 12 weeks. Randomisation was stratified by average total daily opioid dose (30-100 mg and >100 mg equivalents of oral morphine sulphate). The primary endpoint was proportion of responders. A responder had at least three spontaneous bowel movements (SBMs) per week with an increase from baseline of at least one SBM per week for at least 9 weeks of the 12-week treatment period including at least three of the last 4 weeks. Efficacy endpoints were analysed by intention to treat and the safety population included all patients who received at least one dose of study drug. These trials have both been completed and are registered with ClinicalTrials.gov, numbers NCT01965158 and NCT01993940. In COMPOSE-1, 547 patients were recruited between Aug 29, 2013, and Jan 22, 2015, and were randomly assigned to receive naldemedine (n=274) or placebo (n=273). Patients for COMPOSE-2 were recruited between Nov 4, 2013, and June 9, 2015; 553 patients were randomly assigned to receive naldemedine (n=277) or placebo (n=276). Five patients were enrolled at more than one site, so were excluded from the intention-to-treat population (COMPOSE-1: one per group; COMPOSE-2: one in the naldemedine group, two from the placebo group), with intention-to-treat group sizes of 273 in the naldemedine group and 272 in the placebo group in COMPOSE-1, and 276 in the naldemedine group and 274 in the placebo group in COMPOSE-2. The proportion of responders in both trials was significantly higher with naldemedine than with placebo in COMPOSE-1 (130 responders [47·6%] of 273 in the naldemedine group vs 94 responders [34·6%] of 272 in the placebo group, difference 13·0% [95% CI 4·8-21·3]; p=0·002) and in COMPOSE-2 (145 [52·5%] of 276 vs 92 [33·6%] of 274, difference 18·9% [10·8-27·0]; p<0·0001). Incidence of adverse events with naldemedine was similar to placebo (COMPOSE-1: 132 [49%] of 271 in the naldemedine group vs 123 [45%] of 272 in the placebo group; COMPOSE-2: 136 [50%] of 271 vs 132 [48%] of 274). Treatment-related adverse events were noted in 59 (22%) of 271 patients in the naldemedine group and 45 (17%) of 272 in the placebo group in COMOPOSE-1, and in 54 (20%) of 271 patients in the naldemedine group and 31 (11%) of 274 in the placebo group of COMPOSE-2; the between-group differences were largely due to gastrointestinal disorders, which were more common with naldemedine than placebo (COMPOSE-1: 40 [15%] patients in the naldemedine group vs 18 [7%] in the placebo group; COMPOSE-2: 42 [16%] vs 20 [7%]). Naldemedine treatment led to a significantly higher responder rate than did placebo and was generally well tolerated. These results support that naldemedine could be a new option for the treatment of opioid-induced constipation in patients with chronic non-cancer pain. Shionogi & Co, Ltd.

Giannini, Susana Pimentel Pinto; Latorre, Maria do Rosário Dias de Oliveira; Ferreira, Léslie Piccolotto

2013-01-01

We aimed at verifying an association between voice disorders/stress and loss of work ability among female teachers who work in São Paulo's public school system. This is a paired case- control study. The case group was composed offiteachers with alterations in speech and larynges assessments, and the control group was formed by teachers without alterations in these evaluations who work in the same schools. Both groups answered the following questionnaires: Conditions of Vocal Production-Teachers, Job Stress Scale, and Work Ability Index. The analysis was performed using the chi-square association test and logistic regression models with the purpose of estimating the association between independent variables and voice disorders. We found differences between the groups in relation to stress in the workplace under high demand, a situation that poses greater risks of adverse reactions to the workers' physical and mental health. Regarding the ability to work, the categories poor and moderate ability for work are associated with voice disorders, regardless of job stress factors, age, and the unsatisfactory acoustic properties of the classrooms. This study confirmed the association between voice disorders and job stress, as well as between voice disorders and loss of work ability.

Learning disabled and average readers' working memory and comprehension: does metacognition play a role?

PubMed

Swanson, H L; Trahan, M

1996-09-01

The present study investigates (a) whether learning disabled readers' working memory deficits that underlie poor reading comprehension are related to a general system, and (b) whether metacognition contributes to comprehension beyond what is predicted by working memory and word knowledge. To this end, performance between learning and disabled (N = 60) and average readers (N = 60) was compared on the reading comprehension, reading rate, and vocabulary subtests of the Nelson Skills Reading Test, Sentence Span test composed of high and low imagery words, and a Metacognitive Questionnaire. As expected, differences between groups in working memory, vocabulary, and reading measures emerged, whereas ability groups were statistically comparable on the Metacognitive Questionnaire. A within-group analysis indicated that the correlation patterns between working memory, vocabulary, metacognition, and reading comprehension were not the same between ability groups. For predicting reading comprehension, the metacognitive questionnaire best predicted learning disabled readers' performance, whereas the working memory span measure that included low-imagery words best predicted average achieving readers' comprehension. Overall, the results suggest that the relationship between learning disabled readers' generalised working memory deficits and poor reading comprehension may be mediated by metacognition.

The swan-song phenomenon: last-works effects for 172 classical composers.

PubMed

Simonton, D K

1989-03-01

Creative individuals approaching their final years of life may undergo a transformation in outlook that is reflected in their last works. This hypothesized effect was quantitatively assessed for an extensive sample of 1,919 works by 172 classical composers. The works were independently gauged on seven aesthetic attributes (melodic originality, melodic variation, repertoire popularity, aesthetic significance, listener accessibility, performance duration, and thematic size), and potential last-works effects were operationally defined two separate ways (linearly and exponentially). Statistical controls were introduced for both longitudinal changes (linear, quadratic, and cubic age functions) and individual differences (eminence and lifetime productivity). Hierarchical regression analyses indicated that composers' swan songs tend to score lower in melodic originality and performance duration but higher in repertoire popularity and aesthetic significance. These last-works effects survive control for total compositional output, eminence, and most significantly, the composer's age when the last works were created.

This study was performed to determine the occupational risks and their effects on the work stress of the health professionals working in state hospitals in the Southeast of Turkey. This cross-sectional and descriptive study was composed of 360 health professionals of the Pazarcık, Ergani, and Şehitkamil State Hospitals between December 2014 and January 2015. The data of the study were obtained by performing the survey which was composed of questions related to the socio-demographic characteristics, factors that were thought to affect the occupational risks and job stress, as well as, the questions of the Work Stress Scale. The analyses of the data have been performed using Student's t test and one-way analysis of variance. The working hours, the number of being on-duty, insomnia, and burnout in health professionals were determined to be with the highest mean scores among other stressful risks and hazards. The mean work stress level, which increases the success by creating the group-stimulus effect, was indicated as 2.4 and 2.5 for the health professionals in Pazarcık and Ergani State Hospital, respectively. However, the stress level which poses a threat for the group-health and efficiency was found to be 4.0 for the health professionals of the Şehitkamil State Hospital. As the exposure of the occupational risks increases in the health professionals, the work stress scores also increase (p < 0.05). The occupational risks and work stress of the health professionals in the Şehitkamil State Hospital should be evaluated in terms of occupational health and safety.

Romantic partners in a market perspective: expectations about what ensures a highly desirable partner.

2013-10-01

This study used the biological market perspective and influential statistical models from the marketing field to investigate males' and females' expectations regarding which combination of characteristics are most relevant in ensuring desirable partnerships for same-sex individuals. Thus, 358 Brazilian undergraduates assessed eight descriptions of same-gender stimulus targets (formulated with different levels of physical attractiveness, social skills, and current or prospective social status) and evaluated the overall desirability of the targets' expected or probable partners. From the possible combinations, three groups emerged: for one group, mainly composed of men, status characteristics were the most important attributes; for the others, mostly composed of women, social skills or physical characteristics were identified as most important in appealing to a desirable partner. This work expands the understanding of variability in male and female romantic expectations, and its implications are discussed from an evolutionary perspective.

A european class is, in France, a class in which we teach a subject in a foreign language, for example science in English. I led, in my European class, during a seven weeks session, group work activities about different participating science actions. There were groups composed of three or four 16 years old students. Each group chose one type of participating science activity among : - Leading a visioconference with an IODP mission on board the Joides Resolution. - Being part of a "science songs community" with Tom Mc Fadden They divided the work and some of them studied the websites and contacted the actors to present the pedagogical or scientific background of their subject. Others had a concrete production like the organization of a visioconference with the Joides Resolution or the creation of a pedagogical song about geology. I will present some results of their work and explain the students motivation linked to this active learning method.

Lejaren A. Hiller, Jr.: A Memorial Tribute to a Chemist-Composer

NASA Astrophysics Data System (ADS)

Wamser, Christian A.; Wamser, Carl C.

1996-07-01

Lejaren Hiller (1924-1994) was trained in chemistry but maintained a lifelong love of music. Like Alexander Borodin, the Russian chemist-composer, but eventually dedicated his career solely to music. His early work on the chemistry of polymers with Fred Wall at the University of Illinois introduced him to the Illiac computer, with which he did Monte Carlo calculations of polymer conformations. He promptly collaborated with Leonard Isaacson, a graduate student also associated with the Wall group, to teach the Illiac to compose music. Using a modified Monte Carlo technique to select the notes and other aspects of the music, they applied increasingly complex rules to define what constituted acceptable music. The result was their String Quartet #4, produced in 1957, often called the Illiac Suite. It is generally acknowledged as the first piece of music composed by a computer. Hiller remained a pioneer in the field of copmuter composition during his distinguished career at the University of Illinois and the State University of New York at Buffalo. This paper traces Hiller's careers in chemistry and music and examines the connections between the two.

The Composer's Program Note for Newly Written Classical Music: Content and Intentions.

PubMed

Blom, Diana M; Bennett, Dawn; Stevenson, Ian

2016-01-01

In concerts of western classical music the provision of a program note is a widespread practice dating back to the 18th century and still commonly in use. Program notes tend to inform listeners and performers about historical context, composer biographical details, and compositional thinking. However, the scant program note research conducted to date reveals that program notes may not foster understanding or enhance listener enjoyment as previously assumed. In the case of canonic works, performers and listeners may already be familiar with much of the program note information. This is not so in the case of newly composed works, which formed the basis of the exploratory study reported here. This article reports the views of 17 living contemporary composers on their writing of program notes for their own works. In particular, the study sought to understand the intended recipient, role and the content of composer-written program notes. Participating composers identified three main roles for their program notes: to shape a performer's interpretation of the work; to guide, engage or direct the listener and/or performer; and as collaborative mode of communication between the composer, performer, and listener. For some composers, this collaboration was intended to result in "performative listening" in which listeners were actively engaged in bringing each composition to life. This was also described as a form of empathy that results in the co-construction of the musical experience. Overall, composers avoided giving too much personal information and they provided performers with more structural information. However, composers did not agree on whether the same information should be provided to both performers and listeners. Composers' responses problematize the view of a program note as a simple statement from writer to recipient, indicating instead a more complex set of relations at play between composer, performer, listener, and the work itself. These relations are illustrated in a model. There are implications for program note writers and readers, and for educators. Future research might seek to enhance understanding of program notes, including whether the written program note is the most effective format for communications about music.

2016-05-01

This research examined cutoff scores for the Effort Index (EI), an embedded measure of performance validity, for the Repeatable Battery for the Assessment of Neuropsychological Status. EI cutoffs were explored for an active-duty military sample composed mostly of patients with traumatic brain injury. Four psychometrically defined malingering groups including a definite malingering, probable to definite malingering, probable malingering, and a combined group were formed based on the number of validity tests failed. Excellent specificities (0.97 or greater) were found for all cutoffs examined (EI ≥ 1 to EI ≥ 3). Excellent sensitivities (0.80 to 0.89) were also found for the definite malingering group. Sensitivities were 0.49 or below for the other groups. Positive and negative predictive values and likelihood ratios indicated that the cutoffs for EI were much stronger for ruling-in than ruling-out malingering. Analyses indicated the validity tests used to form the malingering groups were uncorrelated, which serves to enhance the validity of the formation of the malingering groups. Cutoffs were similar to other research using samples composed predominantly of head-injured individuals. Published by Oxford University Press 2016.

To compare the results of Loop Phonological Working Memory (LPWM) in children without global learning alterations, with lower and average/higher arithmetic performance. The study was conducted with 30 children, between the ages of seven and nine years old, who attended the second or third grade of elementary school in the public network. Exclusion criteria were children with suggestive signs of hearing loss, neurological disorders, poor performance in the reading comprehension test or in speech therapy. The children included in the study were submitted to the subtest of arithmetic of Academic Achievement Test for division into two groups (G1 and G2). The G1 was composed of children with low performance in arithmetic and G2 for children with average/higher performance in arithmetic. All children were submitted to PWM assessment through the repetition of pseudowords test. Statistical analysis was performed using the Mann-Whitney test and a p-value <0.05 was considered significant. The study included 20 girls and 10 boys, mean age 8.7 years. The G1 was composed of 17 children and G2 of 13 children. There was a statistically significant difference between the groups studied for the repetition of pseudowords with three and four syllables. The results of this study provide support for the hypothesis that changes in phonological working memory are related to difficulties in arithmetic tests.

The purpose of this paper is to analyze the self-perception of weight in relation with the body mass index and the body composition of three working groups composed of physically untrained young students, young athletes and patients diagnosed with chronic diseases. The working groups consisted of 110 participants: untrained students, athletes and dialysed patients; 50.9% women and 49.1% men; with an average age of 26.03. The BMI of the patients is significantly higher than the BMI of the athletes and untrained students. No significant differences were found between groups in terms of self-perception of weight. Compared to the physically untrained students and patients, the athletes have a significantly higher level of muscle tissue. The athletes also have a significantly lower adipose tissue than that of the physically untrained students and patients.

The composition of precarity: 'emerging' composers' experiences of opportunity culture in contemporary classical music.

2018-02-28

This paper examines the precarious working lives of 'emerging' composers attempting to build a career in the world of new classical music in the UK. This topic is approached by considering the 'composition opportunity', success in which is seen as an important element in 'making it' in this sphere. We argue that such schemes in fact manifest a crucial tension in the nature of artistic labour, and are, at the very least, problematic in their function as conduits towards full professional identity. They may instead act to maintain the precarious working situation of composers in a neoliberal age. The working lives of artists are all too rarely illuminated, and new music composers are no exception; this survey of 47 emerging composers is the largest study of such individuals in the UK. © London School of Economics and Political Science 2018.

The Composer’s Program Note for Newly Written Classical Music: Content and Intentions

PubMed Central

Blom, Diana M.; Bennett, Dawn; Stevenson, Ian

2016-01-01

In concerts of western classical music the provision of a program note is a widespread practice dating back to the 18th century and still commonly in use. Program notes tend to inform listeners and performers about historical context, composer biographical details, and compositional thinking. However, the scant program note research conducted to date reveals that program notes may not foster understanding or enhance listener enjoyment as previously assumed. In the case of canonic works, performers and listeners may already be familiar with much of the program note information. This is not so in the case of newly composed works, which formed the basis of the exploratory study reported here. This article reports the views of 17 living contemporary composers on their writing of program notes for their own works. In particular, the study sought to understand the intended recipient, role and the content of composer-written program notes. Participating composers identified three main roles for their program notes: to shape a performer’s interpretation of the work; to guide, engage or direct the listener and/or performer; and as collaborative mode of communication between the composer, performer, and listener. For some composers, this collaboration was intended to result in “performative listening” in which listeners were actively engaged in bringing each composition to life. This was also described as a form of empathy that results in the co-construction of the musical experience. Overall, composers avoided giving too much personal information and they provided performers with more structural information. However, composers did not agree on whether the same information should be provided to both performers and listeners. Composers’ responses problematize the view of a program note as a simple statement from writer to recipient, indicating instead a more complex set of relations at play between composer, performer, listener, and the work itself. These relations are illustrated in a model. There are implications for program note writers and readers, and for educators. Future research might seek to enhance understanding of program notes, including whether the written program note is the most effective format for communications about music. PMID:27881967

2017-01-01

The aim of this study is to describe the beliefs and behaviors of nurse leaders regarding electronic connectedness with their workplace and workplace support. Electronic communication enables leaders' continuous availability to the workplace. This may blur home-work boundaries and contribute to burnout. This mixed-methods study surveyed nurses in 6 acute care hospitals in north Texas. A qualitative phase employed focus groups composed of nurses from participating hospitals to validate and enrich data collected in the quantitative phase. Data showed that leader support directly influenced work-related electronic communication by influencing expectations regarding connectedness. Furthermore, leaders who frequently thought of leaving employment reported significantly lower levels of supervisor support and stronger beliefs that work interfered with home life than other respondents did. Focus group data supported survey findings. Electronic availability of nurse leaders did not directly affect satisfaction, but supervisor support and perception that work interferes with home life strongly and directly affected satisfaction.

The topics of discussion addressed during a three day workshop on commercial application in space are presented. Approximately half of the program was directed towards an overview and orientation to the Space Station Project; the technical attributes of space; and present and future potential commercial opportunities. The remaining time was spent addressing technological issues presented by previously-formed industry working groups, who attempted to identify the technology needs, problems or issues faced and/or anticipated by the following industries: extraction (mining, agriculture, petroleum, fishing, etc.); fabrication (manufacturing, automotive, aircraft, chemical, pharmaceutical and electronics); and services (communications, transportation and retail robotics). After the industry groups presented their technology issues, the workshop divided into smaller discussion groups composed of: space experts from NASA; academia; industry experts in the appropriate disciplines; and other workshop participants. The needs identified by the industry working groups, space station technical requirements, proposed commercial ventures and other issues related to space commercialization were discussed. The material summarized and reported are the consensus from the discussion groups.

Personal and Financial Risk Typologies Among Women Who Engage in Sex Work in Mongolia: A Latent Class Analysis.

2017-08-01

Women engaged in sex work bear a disproportionate burden of HIV infection worldwide, particularly in low- to middle-income countries. Stakeholders interested in promoting prevention and treatment programs are challenged to efficiently and effectively target heterogeneous groups of women. This problem is particularly difficult because it is nearly impossible to know how those groups are composed a priori. Although grouping based on individual variables (e.g., age or place of solicitation) can describe a sample of women engaged in sex work, selecting these variables requires a strong intuitive understanding of the population. Furthermore, this approach is difficult to quantify and has the potential to reinforce preconceived notions, rather than generate new information. We aimed to investigate groupings of women engaged in sex work. The data were collected from a sample of 204 women who were referred to an HIV prevention intervention in Ulaanbaatar, Mongolia. Latent class analysis was used to create subgroups of women engaged in sex work, based on personal and financial risk factors. This analysis found three latent classes, representing unique response pattern profiles of personal and financial risk. The current study approached typology research in a novel, more empirical way and provided a description of different subgroups, which may respond differently to HIV risk interventions.

The dissertation provides an excellent source of scholarly productivity for new doctoral faculty, yet is often neglected because of the demands inherent in the faculty role. The purpose of this paper is to present a case study of a scholar mentor group composed of three graduates of a PhD nursing program and their shared dissertation chair, who acted as a senior scholar mentor to the group. By working together, we have been able to enhance our scholarly productivity by disseminating our dissertations through presentations and publications. The paper will present the evolving process of this working group, summarize outcomes, analyze the challenges, and provide suggestions for future doctoral students and faculty who are working with them. Our experience and scholar mentor model captures the best of both worlds-the benefits of interaction with academic peers and the benefits of having a senior scholar mentor. This was accomplished while all members were at different schools in different cities and states. Although other literatures that document successful collaborations using a peer-mentorship model are available, we were unable to locate any that documents a post-doctoral group with a senior scholar mentor who continued working together after graduation. © 2015 Wiley Periodicals, Inc.

The prospect of biological attacks is a growing strategic threat. Covert aerosol attacks inside a building are of particular concern. In the summer of 2005, the Center for Biosecurity of the University of Pittsburgh Medical Center convened a Working Group to determine what steps could be taken to reduce the risk of exposure of building occupants after an aerosol release of a biological weapon. The Working Group was composed of subject matter experts in air filtration, building ventilation and pressurization, air conditioning and air distribution, biosecurity, building design and operation, building decontamination and restoration, economics, medicine, public health, and public policy. The group focused on functions of the heating, ventilation, and air conditioning systems in commercial or public buildings that could reduce the risk of exposure to deleterious aerosols following biological attacks. The Working Group's recommendations for building owners are based on the use of currently available, off-the-shelf technologies. These recommendations are modest in expense and could be implemented immediately. It is also the Working Group's judgment that the commitment and stewardship of a lead government agency is essential to secure the necessary financial and human resources and to plan and build a comprehensive, effective program to reduce exposure to aerosolized infectious agents in buildings.

Tobacco control in Colombia is regulated by Law 1335 of 2009. The implementation and monitoring of the provisions of this law require strengthening of intersectorial work at the local level. This field note presents an intersectorial work experience that was carried out in the municipality of Tunja (Colombia) to improve tobacco control. The Respirarte Group was established. This group consists of an intersectorial team composed of 15 institutions. The Respirarte Group achieved the following political and community actions: signing of an agreement on tobacco control by government actors, expedition of a local decree to comply with Law 1335 in the municipality, provision of information and communication, and social mobilization and monitoring. This experience serves as a national and international reference and its lessons could be used in the approach to other public health problems. Copyright © 2014 SESPAS. Published by Elsevier Espana.

This study examined the cases of 557 primiparous adolescents, between the ages of 9 and 19, who gave birth at the Obstetric Clinic of the Medical School of the University of Sao Paulo, Brazil, from January 1975 to June 1980. During this period 13,961 deliveries took place, producing an adolescent pregnancy incidence of 3.9%. Based on previous work, 2 groups were established: Group I, composed of 242 women aged 9 to 16, and Group II, composed of 315 women aged 17 to 19. The greatest number of unwed mothers occurred in Group I, the younger age group (98.4%), compared to 54.3% in Group II. An important characteristic in the younger age group was lack of adequate prenatal care. In Group I only 12% received adequate prenatal care, while in Group II, 28.6% received adequate care. Clearly the greatest frequency of prematurity was in the younger group (28.1% of Group I vs. 12.4% of Group II), along with a higher rate of perinatal mortality (4.9% in Group I vs. 2.5% in Group II). Cases of eclampsia occurred more frequently in the younger adolescents (3.3% of Group I vs 1.6% of Group II), but hypertension was more prevalent among the older adolescents (35.9% in Group II vs. 22.7% in Group I). The authors conclude that during pregnancy all adolescents reach similar biologic and endocrine maturity and display similar obstetric performance. The less satisfactory performance among patients in Group I is primarily due to socioeconomic conditions, inadequate resolution of problems related to acceptance of pregnancy, lack of family support, and inadquate prenatal care. The authors believe that the risks associated with adolescent pregnancy could be substantially reduced if adolescents were better informed and received psychological support and adequate prenatal care.

Beyond the Shannon–Khinchin formulation: The composability axiom and the universal-group entropy

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

Tempesta, Piergiulio, E-mail: p.tempesta@fis.ucm.es

2016-02-15

The notion of entropy is ubiquitous both in natural and social sciences. In the last two decades, a considerable effort has been devoted to the study of new entropic forms, which generalize the standard Boltzmann–Gibbs (BG) entropy and could be applicable in thermodynamics, quantum mechanics and information theory. In Khinchin (1957), by extending previous ideas of Shannon (1948) and Shannon and Weaver (1949), Khinchin proposed a characterization of the BG entropy, based on four requirements, nowadays known as the Shannon–Khinchin (SK) axioms. The purpose of this paper is twofold. First, we show that there exists an intrinsic group-theoretical structure behindmore » the notion of entropy. It comes from the requirement of composability of an entropy with respect to the union of two statistically independent systems, that we propose in an axiomatic formulation. Second, we show that there exists a simple universal family of trace-form entropies. This class contains many well known examples of entropies and infinitely many new ones, a priori multi-parametric. Due to its specific relation with Lazard’s universal formal group of algebraic topology, the new general entropy introduced in this work will be called the universal-group entropy. A new example of multi-parametric entropy is explicitly constructed.« less

Simulation for F.C.C. deformation texture by modified pencil glide theory[Face Centered Cubic

1999-11-26

Inspired by the pencil glide theory for b.c.c. metal, modified pencil glide theory for f.c.c. metal was proposed, dividing the 12 glide systems of f.c.c. metal into three groups individually composed of eight {l{underscore}brace}111{r{underscore}brace}{l{underscore}angle}110{r{underscore}angle} glide systems around the principal axes X[100], Y[010] and Z[001]. These assumptions yielded two mathematical solutions {Omega}(3) and {Omega}(1). In {Omega}(3), from the three groups with four complete conjugated glide systems composed of, respectively, two glide systems of common {l{underscore}angle}110{r{underscore}angle} direction, only one group with the maximum plastic work may operate if the requirements are satisfied, otherwise glide systems in {Omega}(1) where one of the fourmore » conjugated glide systems is zero are activated. The model considering the 12 glide systems of f.c.c. as a whole explained many experimentally stable orientations in axisymmetric and rolling deformation. The differences between the two pencil glide theories for b.c.c. and f.c.c. are also discussed with data.« less

Barriers and enabling factors for work-site physical activity programs: a qualitative examination.

Work sites offer a productive setting for physical activity (PA) promoting interventions. Still, PA participation remains low. Thus, the purpose of this study was to examine the reasoning behind commonly reported barriers and enabling factors to participation in PA programs in a work-site setting. Employees from a large city government were recruited to participate in focus groups, stratified by white- and blue-collar occupations. Responses from open-ended questions about factors influencing participation in PA programs were audio recorded and transcribed verbatim. Resulting data were analyzed with open and axial coding. The sample consisted of 60 employees composing 9 focus groups. Although time was the most common barrier between both groups, white-collars workers responded that scheduling and work conflicts were the most common barrier concerning time. Blue-collar workers indicated shift work as their most common barrier. In addition, health was a significant enabling factor for both occupational categories. White-collar workers were much more concerned with appearances and were more highly motivated by weight loss and the hopefulness of quick results than were blue-collar workers. These findings are important in the understanding of PA as it relates to the reasoning behind participation in work-site programs in regard to occupational status.

Genre Complexes in Popular Music

2016-01-01

Recent work in the sociology of music suggests a declining importance of genre categories. Yet other work in this research stream and in the sociology of classification argues for the continued prevalence of genres as a meaningful tool through which creators, critics and consumers focus their attention in the topology of available works. Building from work in the study of categories and categorization we examine how boundary strength and internal differentiation structure the genre pairings of some 3 million musicians and groups. Using a range of network-based and statistical techniques, we uncover three musical “complexes,” which are collectively constituted by 16 smaller genre communities. Our analysis shows that the musical universe is not monolithically organized but rather composed of multiple worlds that are differently structured—i.e., uncentered, single-centered, and multi-centered.

Our analysis shows that the musical universe is not monolithically organized but rather composed of multiple worlds that are differently structured-i.e., uncentered, single-centered, and multi-centered.

In this work the microflora present in kefir, a fermented milk product, was studied together with the effect of kefir administration on different groups of indigenous bacteria of mouse bowel. Kefir microflora was composed of lactic acid bacteria, acetic acid bacteria and yeasts. Yeast population was composed of Saccharomyces cerevisiae, S. unisporus, Candida kefir, Kluyveromyces marxianus and K. lactis. The streptococci levels in kefir treated mice increased by 10-fold and the levels of sulfite-reducing clostridia decreased by 100-fold. The number of lactic acid bacteria increased significantly. The administration of kefir significantly increased the lactic acid bacteria counts in the mucosa of the bowel. Ingestion of kefir specifically lowered microbial populations of Enterobacteriaceae and clostridia. This is the first long-term study about the effects of the kefir administration on the intestinal microflora of mice.

Humans have the ability to easily separate a composed speech and to form perceptual representations of the constituent sources in an acoustic mixture thanks to their ears. Until recently, researchers attempt to build computer models of high-level functions of the auditory system. The problem of the composed speech segregation is still a very challenging problem for these researchers. In our case, we are interested in approaches that are addressed to the monaural speech segregation. For this purpose, we study in this paper the computational auditory scene analysis (CASA) to segregate speech from monaural mixtures. CASA is the reproduction of the source organization achieved by listeners. It is based on two main stages: segmentation and grouping. In this work, we have presented, and compared several studies that have used CASA for speech separation and recognition.

This article takes an experiential and anecdotal look at the daily lives and work of film composers as creators of music. It endeavors to work backwards from what practitioners of the art and craft of music do instinctively or unconsciously, and try to shine a light on it as a conscious process. It examines the role of the film composer in his task to convey an often complex set of emotions, and communicate with an immediacy and universality that often sit outside of common language. Through the experiences of the author, as well as interviews with composer colleagues, this explores both concrete and abstract ways in which music can bring meaning and magic to words and images, and as an underscore to our daily lives.

Identification of health risks in workers staying and working on the terrains contaminated with depleted uranium.

PubMed

Milacic, Snezana; Simic, Jadranko

2009-05-01

This study investigated health risks in workers residing and working in terrains contaminated by low ionizing radiation doses which originated from ammunition containing depleted uranium (DU). The studied population was composed of two test groups (T-I, T-II) who were occasionally exposed to DU, and two referent (R-I, R-II) groups not exposed at any time to DU. All of them were evaluated for the following: complete clinical examination and blood count, presence of immature forms and blasts, leukocyte alkaline phosphatase activity and cytogenetic tests. The probability of onset of the characteristic complete biomarkers--chromosomal aberrations, was analyzed using logarithmic function of the Poisson regression. The estimated function of the density of probabilities of Poisson distribution of the chromosomal aberrations in the test group T-II was drastically different from the corresponding distribution of the referent group R-I and to a somewhat lesser extent from the group R-II; Wilcoxon test exactly confirms the presence of a significant difference between the reference group R-II and test group T-II, p < 0.05. The damages to chromosomes and cells were highest in the test group T-II of workers additionally occupationally exposed to DU. The group of workers T-I, who had been exposed to DU working on contaminated terrain, have had certain risks of cell and chromosome damages, and that risk was not greater than the risk to the referent group R-II of workers occupationally exposed to ionizing radiation.

The concept of protecting groups and leaving groups in organic synthesis was applied to the synthesis of siloxane-based molecules. Alkoxy-functionalized siloxane oligomers composed of SiO 4 , RSiO 3 , or R 2 SiO 2 units were chosen as targets (R: functional groups, such as Me and Ph). Herein we describe a novel synthesis of alkoxysiloxane oligomers based on the substitution reaction of trimethylsilyl (TMS) groups with alkoxysilyl groups. Oligosiloxanes possessing TMS groups were reacted with alkoxychlorosilane in the presence of BiCl 3 as a catalyst. TMS groups were substituted with alkoxysilyl groups, leading to the synthesis of alkoxysiloxane oligomers. Siloxane oligomers composed of RSiO 3 and R 2 SiO 2 units were synthesized more efficiently than those composed of SiO 4 units, suggesting that the steric hindrance around the TMS groups of the oligosiloxanes makes a difference in the degree of substitution. This reaction uses TMS groups as both protecting and leaving groups for SiOH/SiO - groups. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

Nonaqueous redox flow batteries have attracted recent attention with their potential for high electrochemical storage capacity, with organic electrolytes serving as solvents with a wide electrochemical stability window. Organic molecules can also serve as electroactive species, where molecules with low reduction potentials or high oxidation potentials can provide substantial chemical energy. To identify promising electrolytes in a vast chemical space, high-throughput screening (HTS) of candidate molecules plays an important role, where HTS is used to calculate properties of thousands of molecules and identify a few organic molecules worthy of further attention in battery research. Here, in this work, we presentmore » reduction and oxidation potentials obtained from HTS of 4178 molecules. The molecules are composed of base groups of five- or six-membered rings with one or two functional groups attached, with the set of possible functional groups including both electron-withdrawing and electron-donating groups. In addition to observing the trends in potentials that result from differences in organic base groups and functional groups, we analyze the effects of molecular characteristics such as multiple bonds, Hammett parameters, and functional group position. In conclusion, this work provides useful guidance in determining how the identities of the base groups and functional groups are correlated with desirable reduction and oxidation potentials.« less

Aerodynamic tests were made of seven full-scale 10-foot-diameter propellers of recent design comprising three groups. The first group was composed of three propellers having Clark y airfoil sections and the second group was composed of three propellers having R.A.F. 6 airfoil sections, the propellers of each group having 2, 3, and 4 blades. The third group was composed of two propellers, the 2-blade propeller taken from the second group and another propeller having the same airfoil section and number of blades but with the width and thickness 50 percent greater. The tests of these propellers reveal the effect of changes in solidity resulting either from increasing the number of blades or from increasing the blade width propeller design charts and methods of computing propeller thrust are included.

Formal groups and Z-entropies

PubMed Central

2016-01-01

We shall prove that the celebrated Rényi entropy is the first example of a new family of infinitely many multi-parametric entropies. We shall call them the Z-entropies. Each of them, under suitable hypotheses, generalizes the celebrated entropies of Boltzmann and Rényi. A crucial aspect is that every Z-entropy is composable (Tempesta 2016 Ann. Phys. 365, 180–197. (doi:10.1016/j.aop.2015.08.013)). This property means that the entropy of a system which is composed of two or more independent systems depends, in all the associated probability space, on the choice of the two systems only. Further properties are also required to describe the composition process in terms of a group law. The composability axiom, introduced as a generalization of the fourth Shannon–Khinchin axiom (postulating additivity), is a highly non-trivial requirement. Indeed, in the trace-form class, the Boltzmann entropy and Tsallis entropy are the only known composable cases. However, in the non-trace form class, the Z-entropies arise as new entropic functions possessing the mathematical properties necessary for information-theoretical applications, in both classical and quantum contexts. From a mathematical point of view, composability is intimately related to formal group theory of algebraic topology. The underlying group-theoretical structure determines crucially the statistical properties of the corresponding entropies. PMID:27956871

The goal of this work is to analyze postural control in Ehlers-Danlos syndrome (EDS) participants in time and frequency domain. This study considered a pathological group composed by 22 EDS participants performing a postural test consisting in maintaining standing position over a force platform for 30s in two conditions: open eyes (OE) and closed eyes (CE). In order to compare pathological group we acquired in the same conditions a control group composed by 20 healthy participants. The obtained center of pressure (COP) signal was analyzed in time and frequency domain using an AR model. Results revealed differences between pathological and control group: EDS participants pointed out difficulties in controlling COP displacements trying to keep it inside the BOS in AP direction and for this reason increased the use of ML mechanism in order to avoid the risk of fall. Also in CE conditions they demonstrated more difficulties in maintaining posture revealing the proprioceptive system is impaired, due to ligament laxity that characterized EDS participants. Frequency domain analysis showed no differences between the two groups, affirming that the changes in time domain reflected really the impairment to the postural control mechanism and not a different strategy assumed by EDS participants. These data could help in decision-making process to establish a correct rehabilitation approach, based on the reinforcing of muscle tone to supply the ligament laxity in order to prevent risks of falls and its consequences.

Kunze, Ursula

2016-04-01

Tick-borne encephalitis (TBE) has been a growing public health problem in Europe and other parts of the world for the past 20 years. In 1999, in order to encourage the control of TBE, international experts created a new body: The International Scientific Working Group on Tick-Borne Encephalitis (ISW-TBE). This Working Group has been composed of internationally recognized scientific experts from tick-borne encephalitis virus (TBEv)-endemic and non-endemic regions with extensive personal expertise in the field and a high level of commitment to improve the knowledge of TBE and to increase the public awareness of TBE. Since the foundation of the Working Group, ISW-TBE members meet annually. Every meeting is dedicated to a specific topic, and since 2004 a yearly conference report has been published to inform the scientific community about the latest developments. Among the specific issues that have been extensively discussed over the years were the following: clinical aspects of the disease, TBE in children and golden agers, epidemiology, possible causes for the increase in TBE incidence in Europe, TBE and awareness, TBE and travel, (low) vaccination rates, and the cooperation with the European Centre for Disease Prevention and Control (ECDC). This paper gives an overview of the most important activities and achievements of the ISW-TBE over the past 17 years. Copyright © 2016 Elsevier GmbH. All rights reserved.

Lithostratigraphy, provenance and facies distribution of Archaean cratonic successions in western Kenya

NASA Astrophysics Data System (ADS)

Ngecu, Wilson M.; Gaciri, Steve J.

1995-10-01

The greenstone belt of the Tanzanian shield in Western Kenya is composed of two supracrustal successions, which form the Nyanzian and Kavirondian Groups. The Nyanzian Group at the base is composed of mafic tholeiitic basalts, calc-alkaline dacites and rhyolites. The group is unconformably overlain by the Kavirondian Group. During recent field mapping, the Kavirondian Group was divided into three formations. The Shivakala Formation consists of thickly bedded basal conglomerates, which are interbedded with thin sandstone beds. The Igukhu Formation conformably overlies the Shivakala Formation and is composed of thickly and locally thinly bedded greywacke. The uppermost Mudaa Formation is composed of blocky mudstones and thinly laminated shales. A high proportion of volcanic, granitic and chert pebbles in the conglomerates, along with abundant quartz, feldspars and mudstone fragments in the greywacke, indicates a mixed provenance of volcanic, granitic and recycled sedimentary rocks. Primary sedimentary structures and lithofacies associations indicate that the conglomerates were deposited in an alluvial fan/fan-delta setting. The greywackes represent proximal turbidites while the mudstone and shales were deposited mainly as distal turbidites. In the study area there is no evidence of transitional nearshore or shallow marine facies transitional to the continental and deep marine facies.

Background Facilitation of local women's groups may reportedly reduce neonatal mortality. It is not known whether facilitation of groups composed of local health care staff and politicians can improve perinatal outcomes. We hypothesised that facilitation of local stakeholder groups would reduce neonatal mortality (primary outcome) and improve maternal, delivery, and newborn care indicators (secondary outcomes) in Quang Ninh province, Vietnam. Methods and Findings In a cluster-randomized design 44 communes were allocated to intervention and 46 to control. Laywomen facilitated monthly meetings during 3 years in groups composed of health care staff and key persons in the communes. A problem-solving approach was employed. Births and neonatal deaths were monitored, and interviews were performed in households of neonatal deaths and of randomly selected surviving infants. A latent period before effect is expected in this type of intervention, but this timeframe was not pre-specified. Neonatal mortality rate (NMR) from July 2008 to June 2011 was 16.5/1,000 (195 deaths per 11,818 live births) in the intervention communes and 18.4/1,000 (194 per 10,559 live births) in control communes (adjusted odds ratio [OR] 0.96 [95% CI 0.73–1.25]). There was a significant downward time trend of NMR in intervention communes (p = 0.003) but not in control communes (p = 0.184). No significant difference in NMR was observed during the first two years (July 2008 to June 2010) while the third year (July 2010 to June 2011) had significantly lower NMR in intervention arm: adjusted OR 0.51 (95% CI 0.30–0.89). Women in intervention communes more frequently attended antenatal care (adjusted OR 2.27 [95% CI 1.07–4.8]). Conclusions A randomized facilitation intervention with local stakeholder groups composed of primary care staff and local politicians working for three years with a perinatal problem-solving approach resulted in increased attendance to antenatal care and reduced neonatal mortality after a latent period.

The NASA Science Mission Directorate (SMD) Education and Public Outreach (EPO) Forums have established a Higher Education Working Group (HEWG), which has explored and surveyed the higher education landscape with regard to different subjects, such as community colleges and diversity. The HEWG is composed of representatives from each of the SMD EPO Forums, along with 'external' members who have rotated in and out, and the co-authors here constitute the present membership, chaired by Nicholas Gross. Most recently, the HEWG has worked to identify the key characteristics of higher education STEM programs that reach diverse populations. While increasing the involvement of students from diverse backgrounds in SMD EPO is a core goal for our community, engaging these students meaningfully requires a dedicated strategy using proven techniques. In reality, while most educational programs have this goal, undertaking it meaningfully is more challenging. For higher education, diversity is a long-standing issue, and the working group could have taken many different paths to explore this important topic. The HEWG has undertaken a review of programs that involve engaging undergraduates from diverse backgrounds in SMD-related research internships or hands-on STEM experiments. This information will be synthesized and documented so that future education efforts can incorporate the most valuable components. Meanwhile, the working group is exploring ways that NASA SMD can be more helpful to higher education faculty and students, and community input is solicited as part of this presentation.

Geologic and hydrogeologic characteristics of the Ogallala Formation and White River Group, Belvoir Ranch near Cheyenne, Laramie County, Wyoming

Bartos, Timothy T.; Diehl, Sharon F.; Hallberg, Laura L.; Webster, Daniel M.

2014-01-01

The geologic and hydrogeologic characteristics of Tertiary lithostratigraphic units (Ogallala Formation and White River Group) that typically compose or underlie the High Plains aquifer system in southeastern Wyoming were described physically and chemically, and evaluated at a location on the Belvoir Ranch in Laramie County, Wyoming. On the basis of this characterization and evaluation, three Tertiary lithostratigraphic units were identified using physical and chemical characteristics determined during this study and previous studies, and these three units were determined to be correlative with three identified hydrogeologic units composing the groundwater system at the study site—a high-yielding aquifer composed of the entire saturated thickness of the heterogeneous and coarse-grained fluvial sediments assigned to the Ogallala Formation (Ogallala aquifer); an underlying confining unit composed primarily of very fine-grained volcaniclastic sediments and mudrocks assigned to the Brule Formation of the White River Group and some additional underlying sediments that belong to either the Brule or Chadron Formation, or both (Brule confining unit); and an underlying low-yielding aquifer composed primarily of poorly sorted fluvial sediments assigned to the Chadron Formation of the White River Group (Chadron aquifer). Despite widely varying sediment heterogeneity and consolidation, some limited hydraulic connection throughout the full vertical extent of the Ogallala aquifer was indicated but not conclusively proven by interpretation of similar chemical and isotopic characteristics, modern apparent groundwater ages, and similar hydraulic-head responses measured continuously in two Ogallala aquifer monitoring wells installed for this study at two different widely separated (83 feet) depth intervals. Additional work beyond the scope of this study, such as aquifer tests, would be required to conclusively determine hydraulic connection within the Ogallala aquifer. Groundwater levels (hydraulic heads) measured continuously using water-level recorders in both monitoring wells completed in the Ogallala aquifer showed a consistent strong upward vertical gradient in the Ogallala aquifer, indicating the potential for water to move from deeper to shallower parts of the aquifer, regardless of the time of year and the presumed effects of pumping of public-supply and industrial wells in the area. Continuous measurement of groundwater levels in the shallowest monitoring well, installed near the water table, and examination of subsequently constructed water-level hydrographs indicated substantial groundwater recharge is likely during the spring of 2009 and 2010 from the ephemeral stream (Lone Tree Creek) located adjacent to the study site that flows primarily in response to spring snowmelt from the adjacent Laramie Mountains and surface runoff from precipitation events. Using the water-table fluctuation method, groundwater recharge was estimated to be about 13 inches for the period beginning in early October 2009 and ending in late June 2010, and about 4 inches for the period beginning in March 2011 and ending in early July 2011. Comparison of previously measured groundwater levels (hydraulic heads) and groundwater-quality characteristics in nearby monitoring wells completed in the Chadron aquifer with those measured in the two monitoring wells installed for this study in the Ogallala aquifer, combined with detailed lithologic characterization, strongly indicated the Brule confining unit hydraulically confines and isolates the Chadron aquifer from the overlying Ogallala aquifer, thus likely limiting hydraulic connection between the two units. Consequently, because of the impermeable nature of the Brule confining unit and resulting hydraulic separation of the Ogallala and Chadron aquifers, and compared with local and regional hydrostratigraphic definitions of the High Plains aquifer system, the groundwater system in Tertiary lithostratigraphic units overlying the Upper Cretaceous Lance Formation at the location studied on the Belvoir Ranch was defined as being composed of, from shallowest to deepest, the High Plains aquifer system (high-yielding Ogallala aquifer only, composed of the saturated Ogallala Formation); the Brule confining unit composed of the Brule Formation of the White River Group and an underlying fine-grained depth interval with sediments that belong to either the Brule or Chadron Formation, or both; and the low-yielding Chadron aquifer (composed of poorly sorted coarse-grained sediments with substantial fine-grained matrix material assigned to the Chadron Formation of the White River Group).

2016-01-01

ABSTRACT OBJECTIVE To analyze the relations between the meanings of working and the levels of doctors work well-being in the context of their working conditions. METHOD The research combined the qualitative methodology of textual analysis and the quantitative one of correspondence factor analysis. A convenience, intentional, and stratified sample composed of 305 Spanish and Latin American doctors completed an extensive questionnaire on the topics of the research. RESULTS The general meaning of working for the group located in the quartile of malaise included perceptions of discomfort, frustration, and exhaustion. However, those showing higher levels of well-being, located on the opposite quartile, associated their working experience with good conditions and the development of their professional and personal competences. CONCLUSIONS The study provides empirical evidence of the relationship between contextual factors and the meanings of working for participants with higher levels of malaise, and of the importance granted both to intrinsic and extrinsic factors by those who scored highest on well-being.

The assignment of the task force was to extend work begun by the National Amphibian Leadership Group. This group, composed of senior USGS scientists, managers, and external authorities, met in Gainesville, Florida, in February 20001. The product of this meeting was a document outlining the framework for a national program to monitor amphibian populations and to conduct research into the causes of declines.

Work-related hand injuries in Ontario: an historical perspective.

PubMed

Schofield, Michel M E

2005-10-01

Worker's compensation legislation was enacted in Ontario almost 90 years ago. Workers injured on the job gave up their right to sue employers and received no-fault compensation from an independent, employer-funded body called the Workmen's Compensation Board. Three academic health sciences centers in Ontario that are recognized for their commitment to patient care, research, and education compose part of the Specialty Program network with the Ontario Workplace Safety and Insurance Board (WSIB). Statistical data from the WSIB database for workers with hand injuries from 1996 to 2003 show an increase in fractures from fall injuries in the group of women older than 60 that may be related to osteoporosis, a common condition in this group.

In this study, a personalization method (Guida, Tardieu, & Nicolas, European Journal of Cognitive Psychology, 21: 862-896 2009) was applied to a free-recall task. Fifteen pairs of words, composed of an object and a location, were presented to 93 participants, who had to mentally associate each pair and subsequently recall the objects. A 30-s delay was introduced on half of the trials, the presentation rate was manipulated (5 or 10 s per item), and verbal and visuospatial working memory tests were administered to test for their effects on the serial curve. Two groups were constituted: a personalized group, for whom the locations were well-known places on their university campus, and a nonpersonalized group, for whom the locations did not refer to known places. Since personalization putatively operationalizes long-term working memory (Ericsson & Kintsch, Psychological Review, 102: 211-245 1995)-namely, the capacity to store information reliably and rapidly in long-term memory-and if we take a dual-store approach to memory, the personalization advantage would be expected to be greater for pre-recency than for recency items. Overall, the results were compatible with long-term working memory theory. They contribute to validating the personalization method as a methodology to characterize the contribution of long-term memory storage to performance in working memory tasks.

2007-08-01

Although the relationships between procedural justice climate and organizational citizenship behaviors have been examined in recent years, little research has explored the mechanism by which procedural justice climate shapes individual employee prosocial behaviors in the workplace. The purpose of this study was to examine the mediating role of a group-level cooperative norm on the relationships between the group-level procedural justice climate and individual-level organizational citizenship behaviors. The survey involved 45 work groups in four different industry fields in Taiwan, including manufacturing, technology, banking, and insurance, and each of the groups was composed of one supervisor and three subordinates. Cross-level analyses using hierarchical linear modeling (HLM) indicated that the cooperative norm fully mediated the relationship between procedural justice climate and individual helping behaviors. Procedural justice climate indirectly affects individual helping behaviors through their effects on the cooperative norm.

The purpose of this study is to determine the high school students' cognitive structures related to the concepts of work. The participants of the study were composed of the students enrolled in 11. and 12. class of an Anatolian high school in Turkey. The data were collected via word association test related to the key concept to determine the students' cognitive structures. The collected data were analyzed according to the content analysis method. In the data analysis process, we determined firstly the number of words, the number of answers and the semantic relations between the words written by students. The words having semantic connections were grouped under the same category. Thus, at the end of the study, high school students' cognitive structures and some alternative conceptions were determined related to concepts of work.

Vision loss and hearing loss in painting and musical composition.

PubMed

Marmor, Michael F

2014-07-01

This article considers the impact of vision and hearing loss on great painters and musical composers. The visual work of Mary Cassatt, Georgia O'Keeffe, Edgar Degas, and Claude Monet all showed alterations as their vision failed. In contrast, Gabriel Fauré, Bedřich Smetana, and Ludwig von Beethoven wrote many of their best compositions while totally deaf, and Georg Friedrich Handel and Frederick Delius struggled to compose late in life when they lost their vision (although their hearing remained excellent). There are 2 major distinctions between the role of vision and hearing for these artistic disciplines. First, there is a surrogate means of "hearing" music, through the musical score, which allows composers to write and edit music while totally deaf. The greatest problem with deafness for a skilled composer is interference from internal noise (tinnitus). There is no surrogate for vision to allow a painter to work when the subject is a blur or the colors on the canvas cannot be distinguished. Second, although the appreciation of art is visual and that of music is auditory, the transcription of both art and musical composition is visual. Thus, visual loss does pose a problem for a composer accustomed to working with good sight, because it disrupts habitual methods of writing and editing music.

Convergence to consensus in heterogeneous groups and the emergence of informal leadership.

PubMed

Gavrilets, Sergey; Auerbach, Jeremy; van Vugt, Mark

2016-07-14

When group cohesion is essential, groups must have efficient strategies in place for consensus decision-making. Recent theoretical work suggests that shared decision-making is often the most efficient way for dealing with both information uncertainty and individual variation in preferences. However, some animal and most human groups make collective decisions through particular individuals, leaders, that have a disproportionate influence on group decision-making. To address this discrepancy between theory and data, we study a simple, but general, model that explicitly focuses on the dynamics of consensus building in groups composed by individuals who are heterogeneous in preferences, certain personality traits (agreeability and persuasiveness), reputation, and social networks. We show that within-group heterogeneity can significantly delay democratic consensus building as well as give rise to the emergence of informal leaders, i.e. individuals with a disproportionately large impact on group decisions. Our results thus imply strong benefits of leadership particularly when groups experience time pressure and significant conflict of interest between members (due to various between-individual differences). Overall, our models shed light on why leadership and decision-making hierarchies are widespread, especially in human groups.

The purpose of this paper is to describe the rationale for and the method of designing a framework for a European curriculum to promote intercultural competence in health care students. The background relating to the migration of people into and across Europe is cited as the factor driving the need for such a project. The project group emerged from the European organisation known as COHEHRE (Consortium of Higher Education Institutes in Health and Rehabilitation in Europe). Composed of a group of nurse educators from 5 European countries it charts the process which led them to create a curriculum framework. The completed work is available in the form of a CD-ROM. The paper describes the steps taken to reach the project outcomes over 4 years. The methods of dissemination of the project outcomes are included. The discussion considers the journey of the group towards the outcomes of the project and identifies the need to discover how effective the framework is in achieving the aims of the group. In conclusion it articulates the hope that this work will improve the care which is shown to all recipients of health care whatever their cultural background. Copyright © 2012 Elsevier Ltd.

Will there be room for the teaching of internal medicine in a university hospital?

PubMed

Junod, Alain F

2002-01-12

To answer the question addressed, two working groups, one made of the staff of a University clinic, the other one composed of practising general internists, have discussed the assets and weaknesses of a University service of Internal Medicine for postgraduate training. The groups agreed on a number of points: patients' characteristics (complexity and co-morbidities), quality of teaching, method acquisition for clinical reasoning, as well as absence of exposure to ambulatory patients and of follow-up. The groups differed in their views related to the lack of training in psychiatry and psychosocial problems or to hospital dysfunctions. Opening of internal medicine to primary care appears to be necessary at the same time as individual qualities among the senior staff are to be developed, such as critical analysis and self-questioning.

We evaluate the monophyly and phylogenetic relationships of the Pristimantis leptolophus species group and describe its external morphology, osteology, and some myological characteristics. We also compare the P. leptolophus species group to other related species groups. The P. leptolophus group is not monophyletic due to the inclusion of P. acatallelus, formerly believed to be part of the P. devillei group. The revised P. leptolophus group is composed of nine named species and six unnamed species. Based on our results, we recognize a new species group, the P. boulengeri species group, composed of eight species, many of which were previously assigned to the P. lacrimosus species group.

Developing technical expertise in medical procedures is an integral component of emergency medicine (EM) practice and training. This article is the work of an expert panel composed of members from the Society for Academic Emergency Medicine (SAEM) Interest Group, the SAEM Technology in Medical Education Committee, and opinions derived from the May 2008 Academic Emergency Medicine Consensus Conference, "The Science of Simulation in Healthcare." The writing group reviewed the simulation literature on procedures germane to EM training, virtual reality training, and instructional learning theory as it pertains to skill acquisition and procedural skills decay. The authors discuss the role of simulation in teaching technical expertise, identify training conditions that lead to effective learning, and provide recommendations for future foci of research.

A kind of single-layer carbon based dots (CDs) with abundant carboxyl functional groups was hybridized with manganese dioxide (MnO 2 ). The resulting nanohybrid is stable and can be well dispersed in water. MnO 2 is capable of oxidizing the substrate 3,3'5,5'-tetramethylbenzidine (TMB) to form a blue product whose absorption (peaking at 655 nm) fades in the presence of glutathione (GSH). A sensitive and selective colorimetric GSH assay was worked out that has a linear response in the 10 to 0.1 µM GSH concentration range, with a 0.095 μM detection limit. The method was applied to the determination of GSH in spiked fetal calf serum where it gave excellent recoveries. Graphical abstract Schematic of the preparation of a nanohybrid composed of manganese dioxide and carbon based dots (MnO 2 /CDs). They can be used for the colorimetric detection of glutathione (GSH) based on the color change of 3,3'5,5'-tetramethylbenzidine (TMB).

Groups of 30 ADD-H boys and 90 normal boys were divided into 30 mixed dyads composed of a normal and an ADD-H boy, and 30 normal dyads composed of 2 normal boys. Dyads were videotaped interacting in 15-minute free-play, 15-minute cooperative task, and 15-minute simulated classroom settings. Mixed dyads engaged in more controlling interaction than normal dyads in both free-play and simulated classroom settings. In the simulated classroom, mixed dyads completed fewer math problems and were less compliant with the commands of peers. ADD-H children spent less simulated classroom time on task and scored lower on drawing tasks than normal peers. Older dyads proved less controlling, more compliant with peer commands, more inclined to play and work independently, less active, and more likely to remain on task during the cooperative task and simulated classroom settings. Results suggest that the ADD-H child prompts a more controlling, less cooperative pattern of responses from normal peers.

Responding to the rape of Indonesian Chinese women and girls.

PubMed

1998-09-01

In May 1998, 168 women and girls were gang-raped during the Jakarta riots. In response, the Humanity Volunteer Team, a nongovernmental organization, set up a Violence Against Women Division. This group is composed of 400 people from diverse backgrounds and ethnic groups who undergo training and then volunteer their services to provide psychological and physical support to the affected victims and their families and to investigate the crimes. The volunteers have adopted a holistic approach and work with the cooperation of private hospitals. They accomplish their work in a climate of fear because it is considered subversive simply to bring this issue to light. Rape survivors and their families, as well as medical staff and volunteers, have been intimidated to the point that many rape survivors have traveled abroad to seek treatment. Long-term prevention strategies should include 1) a state apology to rape survivors and their communities, 2) an independent investigation to expose the perpetrators, and 3) the protection of the civil rights of the minority Chinese in Indonesia.

The Payload Advisory Panel of the Investigators Working Group (IWG) for the Earth Observing System (EOS) met 4 to 6 October 1993 in Herndon, Virginia. The Panel, originally composed of the Interdisciplinary Science Principal Investigators, was expanded to include all Principal Investigators and as such is now the IWG itself. The meeting also addressed directly a report from the EOS Data and Information System (EOSDIS) Advisory Panel. The meeting focused on payload issues in the years 2000 to 2005; however, some subjects in the nearer-term, most significantly EOSDIS, were considered. The overarching theme of convergence in Earth observations set a backdrop for the entire meeting. Other themes included: atmospheric chemistry; remote sensing of the global cycles of energy, water, and carbon in EOS; ocean and land-ice altimetry; and the EOSDIS. The Totol Solar Irradiance Monitoring Report and results from the Accelerated Canopy Chemistry Program are included as appendices.

Database of potential sources for earthquakes larger than magnitude 6 in Northern California

1996-01-01

The Northern California Earthquake Potential (NCEP) working group, composed of many contributors and reviewers in industry, academia and government, has pooled its collective expertise and knowledge of regional tectonics to identify potential sources of large earthquakes in northern California. We have created a map and database of active faults, both surficial and buried, that forms the basis for the northern California portion of the national map of probabilistic seismic hazard. The database contains 62 potential sources, including fault segments and areally distributed zones. The working group has integrated constraints from broadly based plate tectonic and VLBI models with local geologic slip rates, geodetic strain rate, and microseismicity. Our earthquake source database derives from a scientific consensus that accounts for conflict in the diverse data. Our preliminary product, as described in this report brings to light many gaps in the data, including a need for better information on the proportion of deformation in fault systems that is aseismic.

Stellation is a measure of cell physiology and pathology for several cell groups including neural, liver and pancreatic cells. In the present work, we compare the results of a conventional two-dimensional shape index study of both atomic force microscopy (AFM) and fluorescent microscopy images with the results obtained using a new three-dimensional AFM-based shape index similar to sphericity index. The stellation of astrocytes is investigated on nanofibrillar scaffolds composed of electrospun polyamide nanofibers that has demonstrated promise for central nervous system (CNS) repair. Recent work by our group has given us the ability to clearly segment the cells from nanofibrillar scaffolds in AFM images. The clear-featured AFM images indicated that the astrocyte processes were longer than previously identified at 24h. It was furthermore shown that cell spreading could vary significantly as a function of environmental parameters, and that AFM images could record these variations. The new three-dimensional AFM-based shape index incorporates the new information: longer stellate processes and cell spreading. The support of NSF PHY-095776 is acknowledged.

"Regular visiting/on-demand response type long-term care" has recently been established. This will lead to a decrease in the burden on the family, but an increase in the burden of the care personnel who provide this kind of long-term care. The objectives of this study were to clarify the fatigue symptoms of long-term care workers in facilities that provide this kind of long-term care, and examine the related factors in the workplace. An anonymous questionnaire survey was conducted with 96 workers engaged in long-term care in facilities. The questionnaire was composed of cumulative fatigue symptoms index, work situation, supports in the workplace, and the attributes. The subjects were divided into two groups: those who had night shift between PM 6 to AM 8 with or without day shift (night shift group), and those who had only day shift (day shift group). The relationships between the fatigue symptom levels and work situation etc. were compared between the two groups. The night shift group consisted of 47 workers, whose mean age was 42.3 years and whose mean working experience was 6.0 years. The median number of persons they had visited in the previous month was 9. The day shift group consisted of 49 workers, whose mean age was 44.6 years and whose mean working experience was 5.9 years. The median number of persons they visited in the previous month was 9.5. Age and sex distributions showed no difference between the two groups. There was no difference in the work situations and the supports in the workplace, except for working time and the details of care the subjects were providing. The fatigue symptom levels were high in both groups, but in the night shift group the level of physical disorders was higher than in the day shift group. Satisfaction with work, education and training for mental health and consideration for traffic safety when making home visits were negatively related to fatigue symptom levels in both groups. Learning care during the previous year, and the ease of receiving paid holiday were not related to the fatigue symptom levels in the night shift group. This was different in the day shift group. Measures of fatigue symptoms should be performed for both groups. It is desirable that supports, additional to that given in the workplace to the day shift group, be given to the night shift group, and its efficacy be researched.

End groups in small-molecule photovoltaic materials are important owing to their strong influence on molecular stability, solubility, energy levels, and aggregation behaviors. In this work, a series of donor-acceptor pentads (D2 -A-D1 -A-D2 ) were designed and synthesized, aiming to investigate the effect of the end groups on the materials properties and photovoltaic device performance. These molecules share identical central A-D1 -A triads (with benzodithiophene as D1 and 6-carbonyl-thieno[3,4-b]thiophene as A), but with various D2 end groups composed of alkyl-substituted thiophene (T), thieno[3,2-b]thiophene (TT), and 2,2'-bithiophene (BT). The results indicate a relationship between conjugated segment/alkyl chain length of the end groups and the photovoltaic performance, which contributes to the evolving molecular design principles for high efficiency organic solar cells. © 2016 WILEY-VCH Verlag GmbH & Co.

To improve the health surveillance program for workers with a known previous exposure to asbestos in a big metallurgic-mechanical industry from Lombardy, the sources of risk and the different exposure levels hare been reconstructed based on specific jobs. The eligibility criteria and a specific work program including information and organization supports hare been established by a work group composed by health physicians, workers and industrial hygienists. The major goals of the program were: to listen and support each worker who perceives worries about his health status; to prevent, if possible, diseases, especially cancer, resulting from exposure; to document the existing injuries for legal compensation. The resulting actions consist of counselling; indication to follow an adequate life and work style; indication, based on specific request of worker, of sanitary checks of first or eventually second level.

The effects of gender composition on women's experience in math work groups.

2017-06-01

The present studies tested a model outlining the effects of group gender composition on self- and others' perceptions of women's math ability in a truly interactive setting with groups composed entirely of naïve participants (N = 158 4-person groups across 3 studies). One woman in each group was designated to be the "expert" by having her complete a tutorial that gave her task-relevant knowledge for a subsequent group task. Group gender composition was hypothesized to influence perceptions of women's math ability through intrapersonal processes (stereotype threat effects on performance) and interpersonal processes (social cohesion between the expert and other group members). Group composition affected the experts' performance in the group math task, but importantly, it also affected their social cohesion with group members. Moreover, both of these effects-lowered performance and poorer social cohesion in male-dominated groups-made independent contributions in accounting for group gender composition effects on perceptions of women's math ability (Studies 1 and 2). Boundary conditions were examined in a 3rd study. Women who had a history of excelling in math and had chosen a math-intensive STEM major were selected to be the designated experts. We predicted and found this would be sufficient to eliminate the effect of group gender composition on interpersonal processes, and correspondingly the effect on women's perceived math ability. Interestingly (and consistent with past work on stereotype threat effects among highly domain-identified individuals), there were continued performance differences indicative of effects on intrapersonal processes.

The aim of this study was to determine the circumstances of aggressions and patterns of maxillofacial injuries among victims of interpersonal violence. This was a cross-sectional and exploratory study conducted from the analysis of 7,132 medical-legal and social records of interpersonal violence victims seen in a Forensic Medicine and Dentistry Center. Descriptive and multivariate statistics were performed using Multiple Correspondence Analysis. Three groups with different victimization profiles were identified. The first group was mainly composed of men of different age groups, victims of community violence that resulted in facial bones or dentoalveolar fracture. The second group was mainly composed of adolescents (10-19 years) of both sexes, victims of interpersonal violence and without specific pattern of injuries. The third group was composed of adult women (≥ 20 years) victims of domestic violence that resulted in injuries of soft tissues of face or other body regions. The results suggest that sociodemographic and circumstantial characteristics are important factors in victimization by maxillofacial injuries and interpersonal violence.

Relationships between Translation and Transcription Processes during fMRI Connectivity Scanning and Coded Translation and Transcription in Writing Products after Scanning in Children with and without Transcription Disabilities

Students with transcription disabilities (dysgraphia/impaired handwriting, n = 13 or dyslexia/impaired word spelling, n = 16) or without transcription disabilities (controls) completed transcription and translation (idea generating, planning, and creating) writing tasks during fMRI connectivity scanning and compositions after scanning, which were coded for transcription and translation variables. Compositions in both groups showed diversity in genre beyond usual narrative-expository distinction; groups differed in coded transcription but not translation variables. For the control group specific transcription or translation tasks during scanning correlated with corresponding coded transcription or translation skills in composition, but connectivity during scanning was not correlated with coded handwriting during composing in dysgraphia group and connectivity during translating was not correlated with any coded variable during composing in dyslexia group. Results are discussed in reference to the trend in neuroscience to use connectivity from relevant seed points while performing tasks and trends in education to recognize the generativity (creativity) of composing at both the genre and syntax levels.

The objective of this paper was to control ergonomic risks among female cashiers working in a department store belonging to the retail market. This study was conducted between May and November 2010. Participatory ergonomics was applied through knowing and understanding how the company works, establishing the work team (Ergo group), training the team in ergonomics-related topics, and making decisions and interventions. The sample was composed of 71 participants--mostly female cashiers--, and all of them have a musculoskeletal compromise, declaring pain or discomfort mainly in the neck, lower back, right wrist and shoulders. Among others, following problems were found: postural overload, repetitive work, manual load handling, mental fatigue, environmental discomfort, variable work schedules, extended working days, and absence of breaks. In the intervention, the main implemented changes were the redesign of workstation, complete change of chairs and keyboards, and the implementation of a rotation system, as well breaks for compensatory exercises. After that, an evident improvement of found problems was observed, therefore it can be concluded that participatory ergonomics is an attractive methodology, appropriate and efficient for solving and controlling ergonomic risks and problems.

Interprofessional education (IPE) is receiving growing significance both nationally and internationally. Despite this, organizational and curricular changes are posing challenges. The level of need for IPE and how changes can be made to curricula and infrastructure were investigated at the University of Erlangen in Germany. The student working group for interprofessional teaching (AGIL) has turned its attention to these issues. This group is composed of students from medicine, dentistry, molecular medicine, medical technology and speech therapy. In June, 2015, a needs analysis was carried out among the students in the study programs represented in the working group to assess the actual and target situation concerning IPE (n=1,105). In the search for answers and to better measure any needs, contact was sought with instructors. The majority of students feel that they are insufficiently educated in terms of interprofessional skills. A large proportion of the students wish to see expansion of the IPE offerings. Students also expressed a desire for additional spaces and welcomed the idea of an interprofessional learning center. AGIL began establishing interprofessional electives in October 2015. A concept for an interprofessional learning center was developed. Based on the survey results, a need for improvements to curricula and infrastructure can be seen; however, the results are limited to the student point of view. AGIL would like to establish more interprofessional electives. These courses would then facilitate curricular implementation. Modern ideas about study environments could be applied to IPE, in particular to promote informal forms of learning. Contact with instructors was crucial for the project work and should be expanded. Realizing and financing the learning center in Erlangen are now the future goals of AGIL. The aim is to create a foundation for this purpose.

Industry-specific primary prevention measures for promoting mental health of workers were undertaken in 2008 and 2009 as a result of participatory training involving 130 supervisory employees in workplaces of the financial industry. These measures included the following five points suggested to be effective in the industry: 1) proper opportunities for training and career building, 2) control of work time and improving work organization, 3) standardization of tasks, 4) job rotation for sharing work responsibilities, and 5) increasing communication and mutual support. A post-training follow-up survey revealed that participatory, action-oriented training facilitated sharing of feasible measures and mutual support, leading to the development of measures easily introduced and established at each workplace. We concluded that mutually supportive group work of teams composed of members who held similar duty positions and were engaged in similar operations, using the Mental Health Action Checklist as a guiding tool, was effective for realizing implementation of optimally practical and specific measures.

This study investigated the relationship between work-related variables and perceived levels of burnout of therapeutic recreation personnel who work with long-term psychiatric patients in Veterans Administration hospitals. Subjects completed a three-part instrument composed of a demographic questionnaire, the Maslach Burnout Inventory and the Work Environment Scale. Of the 511 subjects surveyed, 287 (56%) responded with usable questionnaires. The demographic, job- and profession-related variables were found to be significantly related to burnout. The eta values were somewhat low. The WES variables accounted for 20.9% of the variance in the burnout measures. The WES variables accounted for 20.9% of the variance in the burnout measures. The most salient relationships emerged between the emotional exhaustion and the depersonalization subscales and clarity, supervisor support, involvement, work pressure, autonomy, innovation, peer cohesion, task orientation and physical comfort. In comparison with other groups of human service professionals, therapeutic recreation personnel experienced low levels of emotional exhaustion, moderate levels of depersonalization, and somewhat lower levels of personal accomplishment.

The American Psychological Association Publications and Communications Board Working Group on Journal Article Reporting Standards for Qualitative Research (JARS-Qual Working Group) was charged with examining the state of journal article reporting standards as they applied to qualitative research and with generating recommendations for standards that would be appropriate for a wide range of methods within the discipline of psychology. These standards describe what should be included in a research report to enable and facilitate the review process. This publication marks a historical moment-the first inclusion of qualitative research in APA Style, which is the basis of both the Publication Manual of the American Psychological Association (APA, 2010) and APA Style CENTRAL, an online program to support APA Style. In addition to the general JARS-Qual guidelines, the Working Group has developed standards for both qualitative meta-analysis and mixed methods research. The reporting standards were developed for psychological qualitative research but may hold utility for a broad range of social sciences. They honor a range of qualitative traditions, methods, and reporting styles. The Working Group was composed of a group of researchers with backgrounds in varying methods, research topics, and approaches to inquiry. In this article, they present these standards and their rationale, and they detail the ways that the standards differ from the quantitative research reporting standards. They describe how the standards can be used by authors in the process of writing qualitative research for submission as well as by reviewers and editors in the process of reviewing research.

1962-01-01

Thirty selected blood-group antibodies (excluding anti-A and anti-B) have been classified as β2M (19S γ) globulin, γ (7S γ) globulin or mixtures, using the following three methods: fractionation on a DEAE-cellulose column; indirect anti-globulin tests, using specific anti-β2M-globulin and anti-γ-globulin sera; and treatment with 2-mercapto-ethanol. With only minor exceptions, results obtained with the three methods were in agreement. Most blood-group antibodies within the Le, MNSs and P systems appear to be `naturally occurring' and these were found to be β2M globulin. Blood-group antibodies within the Rh, K and Jk systems, which had arisen after an antigenic stimulus, were usually γ globulin but were occasionally β2M globulin. Antibodies composed of β2M globulin usually behave as agglutinins but may behave as incomplete antibodies (e.g. some examples of anti-Jka); conversely, antibodies composed of γ globulin usually behave as incomplete antibodies but may behave as agglutinins (e.g. an example of anti-M). The ability to bind complement seems to be related more to the blood-group specificity of the particular antibody than to its molecular size. For example, anti-Jka, when composed either of γ or β2M globulin, seems invariably to bind complement, whereas potent anti-M or anti-Rh, whether composed of γ or β2M globulin, do not bind complement.

Zagvazdin, Yuri

2015-01-01

Alfred Schnittke (1934-1998), a celebrated Russian composer of the twentieth century, suffered from several strokes which affected his left cerebral hemisphere. The disease, however, did not diminish his musical talent. Moreover, he stated that his illness in a way facilitated his work. The composer showed amazingly high productivity after his first and second injuries of the central nervous system. The main topic of this chapter is the effect of strokes on Schnittke's output, creativity, and style of music. A brief biography of the composer with the chronology of his brain hemorrhages is included. In addition, the influence of cerebrovascular lesions on creative potential of other prominent composers such as Benjamin Britten, Jean Langlais, Vissarion Shebalin, Igor Stravinsky, and Ira Randall Thompson is discussed. © 2015 Elsevier B.V.

Abstract Proteocephalidean tapeworms form a diverse group of parasites currently known from 315 valid species. Most of the diversity of adult proteocephalideans can be found in freshwater fishes (predominantly catfishes), a large proportion infects reptiles, but only a few infect amphibians, and a single species has been found to parasitize possums. Although they have a cosmopolitan distribution, a large proportion of taxa are exclusively found in South America. We analyzed the largest proteocephalidean cestode molecular dataset to date comprising more than 100 species (30 new), including representatives from 54 genera (80%) and all subfamilies, thus significantly improving upon previous works to develop a molecular phylogeny for the group. The Old World origin of proteocephalideans is confirmed, with their more recent expansion in South America. The earliest diverging lineages are composed of Acanthotaeniinae and Gangesiinae but most of the presently recognized subfamilies (and genera) appear not to be monophyletic; a deep systematic reorganization of the order is thus needed and the present subfamilial system should be abandoned. The main characters on which the classical systematics of the group has been built, such as scolex morphology or relative position of genital organs in relation to the longitudinal musculature, are of limited value, as demonstrated by the very weak support for morphologically-defined subfamilies. However, new characters, such as the pattern of uterus development, relative ovary size, and egg structure have been identified, which may be useful in defining phylogenetically well-supported subgroups. A strongly supported lineage infecting various snakes from a wide geographical distribution was found. Although several improvements over previous works regarding phylogenetic resolution and taxon coverage were achieved in this study, the major polytomy in our tree, composed largely of siluriform parasites from the Neotropics, remained unresolved and possibly reflects a rapid radiation. The genus Spasskyellina Freze, 1965 is resurrected for three species of Monticellia bearing spinitriches on the margins of their suckers. PMID:25987870

Musculoskeletal disorders (MSDs) compose a large part of occupational diseases in dental professionals, prevention of which is dependent on assessment and improvement of job postures by means of ergonomic interventions. This study was aimed at evaluation of ergonomic conditions of the profession of dentists and also at assessing the relationship between MSDs and conditions of work. This cross-sectional study was performed among 65 dentists using the method of Rapid Entire Body Assessment (REBA). The prevalence of MSDs was obtained by the use of the Nordic Musculoskeletal Questionnaire (NMQ). In this investigation, the prevalence of MSDs for different body parts was: 75.9% for the neck, 58.6% for the shoulders, 56.9% for the upper back, 48.3% for the lower back and 44.8% for the wrist. Job analysis by the use of REBA showed that 89.6% of limbs in group A and 79.3% of limbs in group B had a score > 4. Only neck and lower back pain have significant relationship with the risk levels obtained using the REBA method. It can be concluded that work postures of dentists need to be improved. In addition to education, work station design, rest period during work and regular physical activities should be taken into account.

There are only 3 studies comparing the efficacy of 2 different types of lock used in totally implantable catheters regarding occlusion or reflux dysfunction. The present study contains the largest published casuistry (862 patients) and is the only one that analyzes 3 parameters: occlusion, reflux dysfunction, and flow dysfunction. This was a retrospective study of patients operated at a large oncology center and followed up in the outpatient clinic between 2007 and 2015. The patients were divided into 2 groups according to the type of lock: the Hep group (heparine), whose lock was composed of saline solution 0.9% with heparin (100 IU/mL) and the SS group (saline solution), whose lock was composed of saline solution 0.9%. The Hep group was composed of 270 patients (31%) and the SS group of 592 patients (69%). Regarding occlusion, there were 8 cases in the Hep group (2.96%) and 8 in the SS group (1.35%; P = 0.11); in relation to reflux dysfunction, there were 8 cases in the Hep group (2.96%) and 8 in the SS group (1.35%; P = 0.11); in relation to flow dysfunction, there was 1 case in the Hep group (0.37%) and 4 cases in the SS group (0.68%; P = 1). There was no statistically significant difference between the groups regarding occlusion, reflux dysfunction, and flow dysfunction. Copyright © 2017 Elsevier Inc. All rights reserved.

The main purpose of urine cytology is to detect high-grade urothelial carcinoma. With this principle in mind, The Paris System (TPS) Working Group, composed of cytopathologists, surgical pathologists, and urologists, has proposed and published a standardized reporting system that includes specific diagnostic categories and cytomorphologic criteria for the reliable diagnosis of high-grade urothelial carcinoma. This paper outlines the essential elements of TPS and the process that led to the formation and rationale of the reporting system. TPS Working Group, organized at the 2013 International Congress of Cytology, conceived a standardized platform on which to base cytologic interpretation of urine samples. The widespread dissemination of this approach to cytologic examination and reporting of urologic samples and the scheme's universal acceptance by pathologists and urologists is critical for its success. For urologists, understanding the diagnostic criteria, their clinical implications, and limitations of TPS is essential if they are to utilize urine cytology and noninvasive ancillary tests in a thoughtful and practical manner. This is the first international/inclusive attempt at standardizing urinary cytology. The success of TPS will depend on the pathology and urology communities working collectively to improve this seminal paradigm shift, and optimize the impact on patient care.

Convergence to consensus in heterogeneous groups and the emergence of informal leadership

Gavrilets, Sergey; Auerbach, Jeremy; van Vugt, Mark

2016-01-01

When group cohesion is essential, groups must have efficient strategies in place for consensus decision-making. Recent theoretical work suggests that shared decision-making is often the most efficient way for dealing with both information uncertainty and individual variation in preferences. However, some animal and most human groups make collective decisions through particular individuals, leaders, that have a disproportionate influence on group decision-making. To address this discrepancy between theory and data, we study a simple, but general, model that explicitly focuses on the dynamics of consensus building in groups composed by individuals who are heterogeneous in preferences, certain personality traits (agreeability and persuasiveness), reputation, and social networks. We show that within-group heterogeneity can significantly delay democratic consensus building as well as give rise to the emergence of informal leaders, i.e. individuals with a disproportionately large impact on group decisions. Our results thus imply strong benefits of leadership particularly when groups experience time pressure and significant conflict of interest between members (due to various between-individual differences). Overall, our models shed light on why leadership and decision-making hierarchies are widespread, especially in human groups. PMID:27412692

Music is used in healthcare to promote physical and psychological well-being. As clinical applications of music continue to expand, there is a growing need to understand the biological mechanisms by which music influences health. Here we explore the neurochemistry and social flow of group singing. Four participants from a vocal jazz ensemble were conveniently sampled to sing together in two separate performances: pre-composed and improvised. Concentrations of plasma oxytocin and adrenocorticotropic hormone (ACTH) were measured before and after each singing condition to assess levels of social affiliation, engagement and arousal. A validated assessment of flow state was administered after each singing condition to assess participants' absorption in the task. The feasibility of the research methods were assessed and initial neurochemical data was generated on group singing. Mean scores of the flow state scale indicated that participants experienced flow in both the pre-composed (M = 37.06) and improvised singing conditions (M = 34.25), with no significant difference between conditions. ACTH concentrations decreased in both conditions, significantly so in the pre-composed singing condition, which may have contributed to the social flow experience. Mean plasma oxytocin levels increased only in response to improvised singing, with no significant difference between improvised and pre-composed singing conditions observed. The results indicate that group singing reduces stress and arousal, as measured by ACTH, and induces social flow in participants. The effects of pre-composed and improvised group singing on oxytocin are less clear. Higher levels of plasma oxytocin in the improvised condition may perhaps be attributed to the social effects of improvising musically with others. Further research with a larger sample size is warranted. PMID:26441614

The purpose of the work is to compare the influence of the multilamellarity, phase state, lipid head groups and ionic media on the origin of the surface potential of lipid membranes. With this aim, we present a new analysis of the zeta potential of multilamellar and unilamellar vesicles composed by phosphatidylcholines (PC) and phosphatidylethanolamines (PE) dispersed in water and ionic solutions of polarizable anions, at temperatures below and above the phase transition. In general, the adsorption of anions seems to explain the origin of the zeta potential in vesicles only above the transition temperature (Tc). In this case, the sign of the surface potential is ascribed to a partial orientation of head group moiety toward the aqueous phase. This is noticeable in PC head groups but not in PEs, due to the strong lateral interaction between PO and NH group in PE. Copyright © 2015 Elsevier B.V. All rights reserved.

2001-01-01

The aim of the study was to assess the health risk of workers performing specific jobs in the process of the rubber footwear production by defining the cause and length of temporary work disability, as well as mortality causes and level. The analysis was carried out in the groups of workers performing the following jobs: mixing, mill operation, pressing and vulcanizing (A); semi-product preparation and calendaring (B); finishing and sorting (C); production of polyvinyl chloride footwear (D); and auxiliary works (E). The sickness absence study covered all workers (208 men and 315 women) employed in a large rubber footwear company and performing all above-listed jobs in 1995. Standardized sick days ratio was used to analyze the risk of temporary work disability. Mortality rate was estimated on the basis of the results of the cohort study performed in the same company among workers who had worked at least three months during the years 1945-1985. The follow-up continued until 31 December 1997. The present study included sub-cohorts composed of 5628 men and 7197 women, performing jobs listed above. The results of both studies indicated the enhanced risk of cardiovascular diseases among workers employed in the basic phases of the production process. The increased risk of the diseases of the digestive system was observed in men and women employed in: finishing, sorting and packing of the products (group C); in men involved in mixing, pressing and vulcanizing (group A); and in women engaged in auxiliary works (group E). In addition, the enhanced risk of sickness absence due to the diseases of the respiratory, digestive, or genitourinary systems was related to the enhanced risk of death from malignant neoplasms in a given site. The analysis showed that the temporary work disability may be regarded as a parameter useful in early assessment of health effects of the work environmental hazards.

Thirteen flavonol glycosides were isolated from the petals of Rosa species belonging to the section Gallicanae, and their structures were identified from their spectroscopic data. These flavonol glycosides, along with two flavonol glycosides isolated from Rosa rugosa, in the petals of 31 Rosa species belonging to sections Gallicanae, Cinnamomeae, Caninae, and Synstylae were quantitatively analyzed by UPLC. The results indicated that the species belonging to these sections could be classified into four types (Type A, B, C and D) based on the pattern of flavonol glycoside contents, whereas the R. rugosa flavonol glycosides were detected only in section Cinnamomeae. A principal components analysis (PCA) calculated from the 15 flavonol glycosides contained in these samples supported the presence of four types. The distribution of the species in Type D (a group of Cinnamomeae) was shown to reflect close interrelationships, but species in Type B (one group of Gallicanae) could be subdivided into two groups, one of which contained species in section Synstylae. Moreover, the flavonol glycosides were grouped by sugar moieties: a disaccharide composed of two hexoses (S1), a hexose (S2), including a hexose with galloyl group, a pentose (S3), and a disaccharide composed of a hexose and a pentose (S4). The ratios of the amounts of S1-S4 to total flavonol glycoside content indicated that differences among the four sections were more distinctive than the amounts of the 15 flavonol glycosides. The 31 samples were divided into Type B, composed of one type of Gallicanae and Synstylae, Type A+C, composed of another type of Gallicanae and Caninae, and Type D, composed of Cinnamomeae. The R. rugosa flavonol glycosides were shown to be important chemotaxonomic markers for the classification of species in Cinnamomeae, and this method of using flavonol glycosides as chemotaxonomic markers could be useful for the identification of Rosa species belonging to sections Gallicanae, Cinnamomeae, Caninae, and Synstylae.

The P300 event-related potential is a well-known pattern in the electroencephalogram (EEG). This kind of brain signal is used for many different brain-computer interface (BCI) applications, e.g., spellers, environmental controllers, web browsers, or for painting. In recent times, BCI systems are mature enough to leave the laboratories to be used by the end-users, namely severely disabled people. Therefore, new challenges arise and the systems should be implemented and evaluated according to user-centered design (USD) guidelines. We developed and implemented a new system that utilizes the P300 pattern to compose music. Our Brain Composing system consists of three parts: the EEG acquisition device, the P300-based BCI, and the music composing software. Seventeen musical participants and one professional composer performed a copy-spelling, a copy-composing, and a free-composing task with the system. According to the USD guidelines, we investigated the efficiency, the effectiveness and subjective criteria in terms of satisfaction, enjoyment, frustration, and attractiveness. The musical participants group achieved high average accuracies: 88.24% (copy-spelling), 88.58% (copy-composing), and 76.51% (free-composing). The professional composer achieved also high accuracies: 100% (copy-spelling), 93.62% (copy-composing), and 98.20% (free-composing). General results regarding the subjective criteria evaluation were that the participants enjoyed the usage of the Brain Composing system and were highly satisfied with the system. Showing very positive results with healthy people in this study, this was the first step towards a music composing system for severely disabled people.

Aging is a degenerative process marked by recognized functional, physiological, and metabolic impairments, such as dynapenia and diminished cognitive capacity. Therefore, the search for innovative strategies to prevent/delay these physiological and cognitive disorders is essential to guarantee the independence and life quality of an elderly population. The aim of this work is to verify the effect of a 12-week resistance exercise program on the general physical aptitude and cognitive capacities of elderly and sedentary women. Twenty-nine women (65.87±5.69 years) were divided into two groups. The control group was composed of eight elderly women who met the same inclusion criteria of the study and the strength training group was composed of 29 elderly women who were subjected to a resistance exercise program defined by 12 upper and lower limb exercises combined in 3×10 repetitions with 1-minute interval between repetitions and two resting minutes between exercises (three times/week). Weight loads were fixed between 60% and 75% of the apparent 1 repetition maximum, which was estimated by the test of 10 maximum repetitions. The direct curl was performed for upper body strength evaluation with 2.3 kg dumbbells for 30 seconds, whereas the chair test was used for lower body evaluation (total sit-stand movements in 30 seconds). The cognitive capacities of subjects were evaluated by "The Montreal Cognitive Assessment" questionnaire. After 12 weeks, the elderly group showed significant increases in the average upper body strength (58%), lower body strength (68%), and cognitive capacity (19%). The present study demonstrated that regular resistance exercises could provide significant gains on the upper and lower body strength concomitant to positive improvements on cognitive capacities of elderly women, bringing enhanced life quality.

The reconstruction of the anterior cruciate ligament (ACL) of the knee joint is a standard in ACL complete rupture treatment in athletes. One of the weakest points of this procedure is tibial fixation of grafts. The aim was, firstly, to evaluate patients 3-4 years after primary ACL reconstruction with the use of autologous ipsilateral STGR grafts and with tibial fixation using a bioabsorbable interference screw composed of PLLA-HA or WasherLoc, comparing the postoperative result to the preoperative condition and, secondly, to compare the results between the two groups of patients with different tibial fixation. Group I consisted of 20 patients with a bioabsorbable interference screw composed of PLLA-HA tibial fixation. In Group II, there were 22 patients after ACL reconstruction with the use of WasherLoc tibial fixation. The Lachman test, pivot-shift test, Lysholm Knee Scoring Scale and 2000 International Knee Documentation Committee (2000 IKDC) Subjective Knee Evaluation Form were used to evaluate the results. The intra-group comparison of the results of the 2000 IKDC Subjective Knee Evaluation Form and Lysholm Knee Scoring Scale obtained in the groups studied showed statistically significant differences between the evaluation performed preoperatively and postoperatively. The inter-group comparison of the results of the 2000 IKDC Subjective Knee Evaluation Form and Lysholm Knee Scoring Scale obtained postoperatively showed no statistically significant differences between the two groups. An evaluation 3-4 years after ACL reconstruction with the use of autologous ipsilateral STGR grafts demonstrated significant progress from the preoperative condition to the postoperative result in patients with tibial fixation using a bioabsorbable interference screw composed of PLLA-HA as well as in patients with WasherLoc tibial fixation. There were no differences found between the two groups of patients after ACL reconstruction in terms of manual stability testing or a subjective assessment of knee joint outcomes.

Oxygen tolerance of an in silico-designed bioinspired hydrogen-evolving catalyst in water.

Certain bacterial enzymes, the diiron hydrogenases, have turnover numbers for hydrogen production from water as large as 10(4)/s. Their much smaller common active site, composed of earth-abundant materials, has a structure that is an attractive starting point for the design of a practical catalyst for electrocatalytic or solar photocatalytic hydrogen production from water. In earlier work, our group has reported the computational design of [FeFe](P)/FeS(2), a hydrogenase-inspired catalyst/electrode complex, which is efficient and stable throughout the production cycle. However, the diiron hydrogenases are highly sensitive to ambient oxygen by a mechanism not yet understood in detail. An issue critical for practical use of [FeFe](P)/FeS(2) is whether this catalyst/electrode complex is tolerant to the ambient oxygen. We report demonstration by ab initio simulations that the complex is indeed tolerant to dissolved oxygen over timescales long enough for practical application, reducing it efficiently. This promising hydrogen-producing catalyst, composed of earth-abundant materials and with a diffusion-limited rate in acidified water, is efficient as well as oxygen tolerant.

Repeatable group differences in the collective behaviour of stickleback shoals across ecological contexts

PubMed Central

2018-01-01

Establishing how collective behaviour emerges is central to our understanding of animal societies. Previous research has highlighted how universal interaction rules shape collective behaviour, and that individual differences can drive group functioning. Groups themselves may also differ considerably in their collective behaviour, but little is known about the consistency of such group variation, especially across different ecological contexts that may alter individuals' behavioural responses. Here, we test if randomly composed groups of sticklebacks differ consistently from one another in both their structure and movement dynamics across an open environment, an environment with food, and an environment with food and shelter. Based on high-resolution tracking data of the free-swimming shoals, we found large context-associated changes in the average behaviour of the groups. But despite these changes and limited social familiarity among group members, substantial and predictable behavioural differences between the groups persisted both within and across the different contexts (group-level repeatability): some groups moved consistently faster, more cohesively, showed stronger alignment and/or clearer leadership than other groups. These results suggest that among-group heterogeneity could be a widespread feature in animal societies. Future work that considers group-level variation in collective behaviour may help understand the selective pressures that shape how animal collectives form and function. PMID:29436496

Matsui, Yoshio; Asakawa, Naoki; Iwamori, Satoru

An introductory program “Exercise for engineers in mechanical disassembly” is an exercise that ten students of every team disassemble a motor scooter to the components and then assemble again to the initial form in 15 weeks. The purpose of this program is to introduce mechanical engineering by touching the real machine and learning how it is composed from various mechanical parts to the students at the early period after the entrance into the university. Additional short lectures by young teachers and a special lecture by a top engineer in the industry encourage the students to combine the actual machine and the mechanical engineering subjects. Furthermore, various educations such as group leader system, hazard prediction training, parts filing are included in this program. As a result, students recognize the importance of the mechanical engineering study and the way of group working.

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.

Delivering safe patient care remains an elusive goal. Resolving problems in complex organizations like hospitals requires managers to work together. Safety leadership training that encourages managers to exercise learning-oriented, team-based leadership behaviors could promote systemic problem solving and enhance patient safety. Despite the need for such training, few programs teach multidisciplinary groups of managers about specific behaviors that can enhance their role as leadership teams in the realm of patient safety. The aims of this study were to describe a learning-oriented, team-based, safety leadership training program composed of reinforcing exercises and to provide evidence confirming the need for such training and demonstrating behavior change among management groups after training. Twelve groups of managers from an academic medical center based in the Northeast United States were randomly selected to participate in the program and exposed to its customized, experience-based, integrated, multimodal curriculum. We extracted data from transcripts of four training sessions over 15 months with groups of managers about the need for the training in these groups and change in participants' awareness, professional behaviors, and group activity. Training transcripts confirmed the need for safety leadership team training and provided evidence of the potential for training to increase targeted behaviors. The training increased awareness and use of leadership behaviors among many managers and led to new routines and coordinated effort among most management groups. Enhanced learning-oriented leadership often helped promote a learning orientation in managers' work areas. Team-based training that promotes specific learning-oriented leader behaviors can promote behavioral change among multidisciplinary groups of hospital managers.

Airplane Upset Training Evaluation Report

Airplane upset accidents are a leading factor in hull losses and fatalities. This study compared five types of airplane-upset training. Each group was composed of eight, non-military pilots flying in their probationary year for airlines operating in the United States. The first group, 'No aero / no upset,' was made up of pilots without any airplane upset training or aerobatic flight experience; the second group, 'Aero/no upset,' of pilots without any airplane-upset training but with aerobatic experience; the third group, 'No aero/upset,' of pilots who had received airplane-upset training in both ground school and in the simulator; the fourth group, 'Aero/upset,' received the same training as Group Three but in addition had aerobatic flight experience; and the fifth group, 'In-flight' received in-flight airplane upset training using an instrumented in-flight simulator. Recovery performance indicated that clearly training works - specifically, all 40 pilots recovered from the windshear upset. However few pilots were trained or understood the use of bank to change the direction of the lift vector to recover from nose high upsets. Further, very few thought of, or used differential thrust to recover from rudder or aileron induced roll upsets. In addition, recovery from icing-induced stalls was inadequate.

Kin composition effects on reproductive competition among queenless honeybee workers

Inbar, Shani; Katzav-Gozansky, Tamar; Hefetz, Abraham

2008-05-01

Kin selection and inclusive fitness theories predict that, in hopeless queenless (QL) groups, competition or cooperation will occur over male production among workers of different patrilines. Competition is expected to involve mutual inhibition of reproduction and to affect fertility advertisement. To examine kin effect on these phenomena, we studied QL groups of honeybee workers comprising three types of kin structure: groups composed of pure single patrilines, groups composed of three mixed patrilines (all originating from colonies headed by single-drone-inseminated queens), and control groups composed of bees originating from naturally mated queens. Global assessment of ovarian development, irrespective of patriline composition, revealed no differences among group types. In contrast, the performance of specific patrilines revealed that, in the three-mixed-patriline groups, some patrilines were reproductively suppressed compared to their performance when reared as a pure single patriline, resulting in an uneven share of reproduction. Analysis of the fertility signal produced by Dufour’s gland revealed kin composition effects, which may reflect the bees’ competitive efforts. Although patriline effects on worker reproductive superiority have been shown in QL colonies, we were able to investigate specific patriline performance both in competitive and noncompetitive situations here for the first time. The results are consistent with the hypothesis that reproductive and pheromonal competitions in QL groups are affected by the number of subfamilies populating a colony and that these act as coalitions. The results also emphasize that within-colony heterogeneity, in the form of multiple patrilines, has far-reaching consequences on social evolution.

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

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.

The purpose of this study was to evaluate the contribution of working memory at the word and sentence levels of language to reading and writing outcomes. Measures of working memory at the word and sentence levels, reading and writing, were administered to 2nd (N = 122), 4th (N = 222), and 6th (N = 105) graders. Structural equation modeling was used to evaluate whether the 2 predictor working memory factors contributed unique variance beyond their shared covariance to each of 5 outcome factors: handwriting, spelling, composing, word reading, and reading comprehension. At each grade level, except for handwriting and composing in 6th grade, the word-level working memory factor contributed unique variance to each reading and writing outcome. The text-level working memory factor contributed unique variance to reading comprehension in 4th and 6th grade. The clinical significance of these findings for assessment and intervention is discussed.

2016-11-01

The present study distinguishes three memory stages across the lifespan, and aims to compare episodic and semantic autobiographical memory in healthy older adults, with amnesic mild cognitive impairment, and with Alzheimer's disease. This information can offer evidence about the way semantic and episodic autobiographical memory work, and how the disease affects them. The sample was composed of 56 people, all aged over 60 years; 15 with amnestic mild cognitive impairment, 12 with Alzheimer's disease and 29 healthy older people. Participants were evaluated with the Autobiographical Memory Interview. A mixed anova showed significant main effects of memory and time-period, and significant interactions of memory × group, time-period × group and memory × time × group. Assessment of autobiographical memory provides information to differentiate amnestic mild cognitive impairment patients from Alzheimer's disease patients. Although the decline in episodic memory starts with the onset of the disease, semantic memory is maintained until moderate stages of dementia.

The aim of the study was to define associations between intensity of perimenstrual complaints, the type of job performed and working conditions, taking also account of non-occupational factors. The study preceding the development of a preventive program was carried out in a group of women employed in work settings different in the character and burden of adverse agents. The group was composed of 142 women, aged 21-45 years, employed in a cosmetics manufacture plant (27%) and a bank (27%), as well as of hospital and ambulatory nurses and auxiliary personnel (50%). A questionnaire on premenstrual and menstrual complaints, working conditions, characteristics of the women and their household duties load was the main tool of the study. The study revealed that about 80% of women experienced premenstrual and about 75% menstrual symptoms, which were strongly intensified in 40% of women. After applying logistic regression, it was found that physical workload and occupational stress were the major occupational risk factors, whereas chronic diseases, age, household duties load and alcohol consumption were the major non-occupational risk factors. The evidenced relationship between complaints and adverse agents typical of the job performed should prompt occupational medicine physicians to more comprehensive analysis of individual jobs in view of reducing occupational load.

Workplace health promotion (WHP) is important to prevent work-related diseases, reduce workplace hazards, and improve personal health of the workers. Health promotion projects were launched through the centers of WHP funded by the Taiwan Bureau of Health Promotion since 2003. Hence, the aim of this study is to evaluate the impact of WHP programs intervention from 2003 to 2007. The intervention group consisted of 838 business entities which had ever undergone counseling of the three centers in northern, central, and southern Taiwan from 2003 to 2007. The control group was composed of 1000 business entities randomly selected from the business directories of the Ministry of Economic Affairs, Taiwan. The questionnaire survey included general company profiles and the assessment of workplace health according to the five action areas of the Ottawa Charter for Health Promotion. We have received 447 (53.3%) questionnaires from the intervention group and 97 questionnaires from the control group. The intervention group was more effective in using the external resources and medical consultation, and they had better follow-up rates of the abnormal results of annual health examinations. Compared to the control group, the intervention group had a significantly decreased smoking rate in 246 companies (61.2%) and a reduced second-hand smoke exposure in 323 companies (78.6%) (p<0.001). By means of the intervention of WHP programs, we can enhance the awareness of the enterprises and the employees to improve worksite health and to create a healthy work environment. PMID:26954498

2011-01-01

The objective of the study presented here was to examine the incidence of bruxism in patients suffering from temporomandibular disorders. Two cohorts of patients suffering from temporomandibular disorders were evaluated. One group, composed of 163 patients, was asked specifically about the occurrence of bruxism, while the other group, composed of 200 patients, was not specifically asked about bruxism (self-reporting). The incidence of bruxism was only 20.5% for the group that only self-reported bruxism, while the incidence was 65% when asked specifically about bruxism. It is critical to ask specifically about bruxism. Patients are more likely to report bruxism when asked specifically about it. It is important to incorporate this as part of a TMD evaluation.

Neurodiversity, Giftedness, and Aesthetic Perceptual Judgment of Music in Children with Autism

PubMed Central

Masataka, Nobuo

2017-01-01

The author investigated the capability of aesthetic perceptual judgment of music in male children diagnosed with autism spectrum disorder (ASD) when compared to age-matched typically developing (TD) male children. Nineteen boys between 4 and 7 years of age with ASD were compared to 28 TD boys while listening to musical stimuli of different aesthetic levels. The results from two musical experiments using the above participants, are described here. In the first study, responses to a Mozart minuet and a dissonant altered version of the same Mozart minuet were compared. In this first study, the results indicated that both ASD and TD males preferred listening to the original consonant version of the minuet over the altered dissonant version. With the same participants, the second experiment included musical stimuli from four renowned composers: Mozart and Bach’s musical works, both considered consonant in their harmonic structure, were compared with music from Schoenberg and Albinoni, two composers who wrote musical works considered exceedingly harmonically dissonant. In the second study, when the stimuli included consonant or dissonant musical stimuli from different composers, the children with ASD showed greater preference for the aesthetic quality of the highly dissonant music compared to the TD children. While children in both of the groups listened to the consonant stimuli of Mozart and Bach music for the same amount of time, the children with ASD listened to the dissonant music of Schoenberg and Albinoni longer than the TD children. As preferring dissonant music is more aesthetically demanding perceptually, these results suggest that ASD male children demonstrate an enhanced capability of aesthetic judgment of music. Subsidiary data collected after the completion of the experiment revealed that absolute pitch ability was prevalent only in the children with ASD, some of whom also possessed extraordinary musical memory. The implications of these results are discussed with reference to the broader notion of neurodiversity, a term coined to capture potentially gifted qualities in individuals diagnosed with ASD.

The long-term clinical value of the optimization of atrioventricular (AVD) and interventricular (VVD) delays in cardiac resynchronization therapy (CRT) remains controversial. We studied retrospectively the association between the frequency of AVD and VVD optimization and 1-year clinical outcomes in the 199 CRT patients who completed the Clinical Evaluation on Advanced Resynchronization study. From the 199 patients assigned to CRT-pacemaker (CRT-P) (New York Heart Association, NYHA, class III/IV, left ventricular ejection fraction <35%), two groups were retrospectively composed a posteriori on the basis of the frequency of their AVD and VVD optimization: Group 1 (n = 66) was composed of patients 'systematically' optimized at implant, at 3 and 6 months; Group 2 (n = 133) was composed of all other patients optimized 'non-systematically' (less than three times) during the 1 year study. The primary endpoint was a composite of all-cause mortality, heart failure-related hospitalization, NYHA functional class, and Quality of Life score, at 1 year. Systematic CRT optimization was associated with a higher percentage of improved patients based on the composite endpoint (85% in Group 1 vs. 61% in Group 2, P < 0.001), with fewer deaths (3% in Group 1 vs. 14% in Group 2, P = 0.014) and fewer hospitalizations (8% in Group 1 vs. 23% in Group 2, P = 0.007), at 1 year. These results further suggest that AVD and VVD frequent optimization (at implant, at 3 and 6 months) is associated with improved long-term clinical response in CRT-P patients.

Costa, Giuseppe

2015-09-01

In order to assess the needs of knowledge about surveillance and registries in Italy and to prepare a proposal for the advancement of monitoring and recording capacity, a working group led by the Italian Association of Epidemiology and composed by the University of Turin, the Institute of Health and Agenas, carried out a survey of definitions and approaches used in public health and consulted the main Italian experts in surveillance and registries. Some of the reflections developed in this project are presented, to assess to which extent they are adaptable to the prospects the program PRIER aims to. Different aspects of the issue are analyzed: from the frame work necessary to identify information needs and how to improve the ability to measure and types of definitions and taxonomies of the registers, to the implications of the choices about what to include in registries on regulation of the instruments and investment priorities for new registries and surveillance.

Biomineralization Guided by Paper Templates.

This work demonstrates the fabrication of partially mineralized scaffolds fabricated in 3D shapes using paper by folding, and by supporting deposition of calcium phosphate by osteoblasts cultured in these scaffolds. This process generates centimeter-scale free-standing structures composed of paper supporting regions of calcium phosphate deposited by osteoblasts. This work is the first demonstration that paper can be used as a scaffold to induce template-guided mineralization by osteoblasts. Because paper has a porous structure, it allows transport of O2 and nutrients across its entire thickness. Paper supports a uniform distribution of cells upon seeding in hydrogel matrices, and allows growth, remodelling, and proliferation of cells. Scaffolds made of paper make it possible to construct 3D tissue models easily by tuning material properties such as thickness, porosity, and density of chemical functional groups. Paper offers a new approach to study mechanisms of biomineralization, and perhaps ultimately new techniques to guide or accelerate the repair of bone.

To investigate the auditory skills of closure and figure-ground and factors associated with health, communication, and attention in air traffic controllers, and compare these variables with those of other civil and military servants. Study participants were sixty adults with normal audiometric thresholds divided into two groups matched for age and gender: study group (SG), comprising 30 air traffic controllers and control group (CG), composed of 30 other military and civil servants. All participants were asked a number of questions regarding their health, communication, and attention, and underwent the Speech-in-Noise Test (SIN) to assess their closure skills and the Synthetic Sentence Identification Test - Ipsilateral Competitive Message (SSI-ICM) in monotic listening to evaluate their figure-ground abilities. Data were compared using nonparametric statistical tests and logistic regression analysis. More individuals in the SG reported fatigue and/or burnout and work-related stress and showed better performance than that of individuals in the CG for the figure-ground ability. Both groups performed similarly and satisfactorily in the other hearing tests. The odds ratio for participants belonging in the SG was 5.59 and 1.24 times regarding work-related stress and SSI-ICM (right ear), respectively. Results for the variables auditory closure, self-reported health, attention, and communication were similar in both groups. The SG presented significantly better performance in auditory figure-ground compared with that of the CG. Self-reported stress and right-ear SSI-ICM were significant predictors of individuals belonging to the SG.

Objective To develop a comprehensive set of common data elements (CDEs), data definitions, case report forms and guidelines for use in spinal cord injury (SCI) clinical research, as part of the CDE project at the National Institute of Neurological Disorders and Stroke (NINDS) of the USA National Institutes of Health. Setting International Working Groups Methods Nine working groups composed of international experts reviewed existing CDEs and instruments, created new elements when needed, and provided recommendations for SCI clinical research. The project was carried out in collaboration with and cross-referenced to development of the International Spinal Cord Society (ISCoS) International SCI Data Sets. The recommendations were compiled, subjected to internal review, and posted online for external public comment. The final version was reviewed by all working groups and the NINDS CDE team prior to release. Results The NINDS SCI CDEs and supporting documents are publically available on the NINDS CDE website and the ISCoS website. The CDEs span the continuum of SCI care and the full range of domains of the International Classification of Functioning, Disability and Health. Conclusions Widespread use of common data elements can facilitate SCI clinical research and trial design, data sharing, and retrospective analyses. Continued international collaboration will enable consistent data collection and reporting, and will help ensure that the data elements are updated, reviewed and broadcast as additional evidence is obtained.

Physical interaction between man and machines is increasing the interest of the research as well as the industrial community. It is known that physical coupling between active persons can be beneficial and increase the performance of the dyad compared to an individual. However, the factors that may result in performance benefits are still poorly understood. The aim of this work is to investigate how the different initial skill levels of the interacting partners influence the learning of a stabilization task. Twelve subjects, divided in two groups, trained in couples in a joint stabilization task. In the first group the couples were composed of two naive, while in the second a naive was trained together with an expert. Results show that training with an expert results in the greatest performance in the joint task. However, this benefit is not transferred to the individual when performing the same task bimanually.

Veronese, Guido; Pepe, Alessandro

2017-07-01

The aim of this work was to discriminate between healthy children and children at risk of developing mental impairments by evaluating the impact on contextual and individual factors of a context characterized by war. We tested the hypothesis that a linear discriminant function composed of trauma, life satisfaction, and affect balance has the power to classify the children as community or clinical referred. Membership of the clinical-referred group was associated with poorer life satisfaction and higher levels of trauma. Community-referred profiles were associated with lesser trauma. Perceived life satisfaction regarding family and school was the main contributor to the discriminant function.

An applied ergonomics intervention program (AEIP) was conducted with male employees who work in the pressing and storage sections of a metal auto parts factory in eastern Thailand. The objective of this study was to reduce worker muscular discomfort at the low back. The study design was a participatory research approach, with quasi-experimental pretest-posttest, and with a non-equivalent control group. Thirty-five persons participated in the AEIP (AEIP group) and 17 persons did not (non-AEIP group). The AEIP was composed of three major categories: (1) top management support; (2) equipment designed for workstations and manual material handling; and (3) administrative intervention, training, and health education. Muscle activity was measured by surface electromyography of the left and right erector spinae, and multifidus muscles; and evaluated by multivariate test for dependent samples (paired observation) and for independent samples. After the AEIP, the low back muscular loads of the AEIP group was significantly reduced, while those of the non-AEIP group were not. Comparison of the means of percentage maximum voluntary contractions (% MVC) of low back muscular activity between the AEIP group and non-AEIP group indicated that the AEIP group had significantly reduced low back muscular load, with a 95% confidence level (p-value < 0.05).

To evaluate the expression of myosin in muscle fibers of the diaphragm in experimental congenital diaphragmatic hernia (CDH). Fetuses of pregnant rats were divided into four groups: External Control (EC), composed of non-manipulated rats; Nitrofen, composed of pregnant rats that received 100 mg of nitrofen (2,4-dichloro-4'nitrodiphenyl ether) diluted in olive oil on gestational day (GD) 9.5, whose fetuses developed CDH (N+) or not (N-), and Olive Oil Placebo (OO), composed of pregnant rats that received the oil on the same GD. The fetuses were collected on GD 18.5, 19.5, 20.5 and 21.5 (term = 22 days). We obtained body weight (BW) and photographed the diaphragm area (DA), hernia area (HA) and subsequent calculated the HA/DA ratio in N+ group. Samples of Diaphragm muscle were processed for histological staining with H/E and immunohistochemistry (IHQ) for myosin. The fetuses of N- and N+ groups had decreased BW and DA compared to EC and OO groups (p < 0.001). HA was decreased on GD 18.5 compared to 21.5 (p < 0.001) and the HA/DA ratio showed no difference. IHQ showed decreased expression of myosin in nitrofen groups. CDH induced by nitrofen model contributes to the understanding of muscularization in the formation of the diaphragm where the myosin expression is decreased.

An ergonomics intervention program (EIP) was conducted with male employees working in the pressing and storage sections of a metal autoparts factory in Samut Prakan Province, Thailand. The objectives of this study were to assess the causes of injuries in the pressing and storage sections of that factory, and to improve working conditions by reducing worker injuries from accidents and low back muscular discomfort, using an EIR The study design used a participatory research approach which was quasi-experimental with pretest-posttest evaluations, with a non-equivalent control group. A total of 172 male participants working in Building A were the target group for assessing causes of injury. A retrospective study of official accident information, and questionnaires for general information, health and muscular discomfort, injury frequency rate (IFR), injury severity rate (ISR), medical expenses, and EIP design. Two groups of employees volunteered for the study on muscular back discomfort. The first group of 35 persons volunteered to participate in the EIP (EIP group), and the second 17 persons from Building B did not (non-EIP group). The EIP was composed of 4 major categories: (1) engineering improvement, (2) change in personal protective equipment, (3) environmental improvement, (4) administrative intervention, training, and health education. Low back muscular discomfort was measured through questionnaires on subjective feelings of muscular discomfort, and by surface electromyography (sEMG). Muscle activities were measured by sEMG of the left and right erector spinae and multifidus muscles, and evaluated by multivariate test for dependent samples (paired observation), and multivariate test for two independent samples. After EIP, IFR decreased 65.46%, ISR decreased 41.02%, and medical expenses decreased 42.79%. The low back muscular loads of the EIP group were significantly reduced, with a 95% confidence level (p < 0.05) while those of the non-EIP group were not. Subjective feelings of muscular discomfort, determined by Wilcoxon Signed Ranks test, showed that after applying the EIP to the EIP group, the mean scores for general bodily discomfort and low back muscular discomfort in the EIP group had significantly reduced, while those of the non-EIP group increased, (p < 0.05).

To characterize historical building materials according to the geographic origin of the quarries from which they have been mined, the relative content of major and trace elements were determined by means of Laser Induced Breakdown Spectroscopy (LIBS) and X-ray Fluorescence (XRF) techniques. 48 different specimens were studied and the entire samples' set was divided in two different groups: the first, used as reference set, was composed by samples mined from eight different quarries located in Seville province; the second group was composed by specimens of unknown provenance collected in several historical buildings and churches in the city of Seville. Data reduction and analysis on laser induced breakdown spectroscopy and X-ray fluorescence measurements was performed using multivariate statistical approach, namely the Linear Discriminant Analysis (LDA), Principal Component Analysis (PCA) and Soft Independent Modeling of Class Analogy (SIMCA). A clear separation among reference sample materials mined from different quarries was observed in Principal Components (PC) score plots, then a supervised soft independent modeling of class analogy classification was trained and run, aiming to assess the provenance of unknown samples according to their elemental content. The obtained results were compared with the provenance assignments made on the basis of petrographical description. This work gives experimental evidence that laser induced breakdown spectroscopy measurements on a relatively small set of elements is a fast and effective method for the purpose of origin identification.

Mafic igneous rocks probe the interiors of their parent objects, reflecting the compositions and mineralogies of their source regions, and the magmatic processes that engendered them. Incompatible trace element contents of mafic igneous rocks are widely used to constrain the petrologic evolution of planets. We focus on incompatible element ratios of martian meteorites to constrain the petrologic evolution of Mars in the context of magma ocean/cumulate overturn models [1]. Most martian meteorites contain some cumulus grains, but regardless, their incompatible element ratios are close to those of their parent magmas. Martian meteorites form two main petrologic/ age groupings; a 1.3 Ga group composed of clinopyroxenites (nakhlites) and dunites (chassignites), and a <1 Ga group composed of basalts and lherzolites (shergottites).

A new form of dosage (MMC-CH) was composed of activated carbon particles adsorbing mitomycin C. Intraperitoneal administration of MMC-CH was tested clinically for prophylactic and therapeutic effects on peritoneal carcinomatosis of gastric cancer. The criteria of MMC-CH's administration were equal or less than 70 years old, more than 40 kg in body weight, no disfunction of liver and kidney, no particular findings in electrocardiography, S2 or S3 in the grade of serosal invasion, P0, P1, P2 or P3 in the grade of peritoneal dissemination, according to the General Rules for the Gastric Cancer Study in Surgery and Pathology by the Japanese Research Society for Gastric Cancer. MMC-CH was given to 44 patients undergoing gastrectomy for gastric cancer in our department from 1985 to 1988. The 44 patients were composed of 12 patients with P0 findings (P0 patients), 8 patients with P1 findings (P1 patients), 12 patients with P2 findings (P2 patients), and 12 patients with P3 findings (P3 patients). MMC-CH at 50 mg/person in terms of mitomycin C was administered intraperitoneally before the operation wound was closed. Fifty-seven patients in our department from 1983 to 1987 for whom the same criteria were applicable and did not receive MMC-CH therapy, served as the control group. The 57 patients were composed of 23 P0 patients, 21 P1 patients, 10 P2 patients, and 3 P3 patients. There was statistically with chi 2 test no significant difference of age, sex, depth of infiltration macroscopically and microscopically defined progression of lymph-nodal metastases between the MMC-CH group and the control group. Survival rate was calculated with Kaplan-Meier's method in the overall patients in each of the MMC-CH group or the control group. The overall survival rate in the MMC-CH group was statistically significantly (p less than 0.01-0.05) higher from day 460 to day 552 and from day 736 to day 800 than that in the control group. Next, the patients were classified into two subgroups, namely the subgroup composed of P0 patients and the subgroup composed of P1, P2, and P3 patients, in order to examine each of the MMC-CH's prophylactic effects on subsequent dissemination or its therapeutic effects on established dissemination. Survival rate was calculated with Kaplan-Meier's method in the two subgroups through the same procedures used for the overall survival rate.(ABSTRACT TRUNCATED AT 400 WORDS)

To evaluate the corneal endothelial changes in patients with chronic renal failure. A total of 128 corneas of 128 subjects were studied, and 3 groups were formed. The first, the dialyzed group, composed of 32 corneas of 32 patients; the second, the nondialyzed group, composed of 34 corneas of 34 patients; and the third, the age-matched control group, composed of 64 corneas of 64 healthy subjects were examined by a specular microscope and the endothelial parameters were compared. The dialyzed group (enhanced level of toxins in the blood) was further analyzed to assess the influence of blood urea, serum creatinine, serum calcium, and serum phosphorus including the duration of dialysis on corneal endothelium. On comparing the 3 groups using analysis of variance and posthoc tests, a significant difference was found in the central corneal thickness (CCT) and endothelial cell density (CD) between the control (CCT: 506 ± 29 μm, CD: 2760 ± 304 cells/mm) and dialyzed groups (CCT: 549 ± 30 μm, CD: 2337 ± 324 cells/mm) [P < 0.001 (CCT); P < 0.001 (CD)]; control and nondialyzed groups (CCT: 524 ± 27 μm, CD: 2574 ± 260 cells/mm) [P = 0.023 (CCT); P = 0.016 (CD)]; and dialyzed and nondialyzed groups [P = 0.002 (CCT); P = 0.007 (CD)]. Using the linear generalized model, a significant correlation was found between the endothelial parameters and blood urea only [P = 0.006 (CCT), 0.002 (coefficient of variation), 0.022 (CD), and 0.026 (percentage of hexagonality)], although the correlation was poorly positive for CCT but poorly negative for the remaining endothelial parameters. Corneal endothelial alteration is present in patients with chronic renal failure, more marked in patients undergoing hemodialysis and with raised blood urea level.

In Study 1, the treatment group ( N = 33 first graders, M = 6 years 10 months, 16 girls) received Slingerland multi-modal (auditory, visual, tactile, motor through hand, and motor through mouth) manuscript (unjoined) handwriting instruction embedded in systematic spelling, reading, and composing lessons; and the control group ( N =16 first graders, M = 7 years 1 month, 7 girls) received manuscript handwriting instruction not systematically related to the other literacy activities. ANOVA showed both groups improved on automatic alphabet writing from memory; but ANCOVA with the automatic alphabet writing task as covariate showed that the treatment group improved significantly more than control group from the second to ninth month of first grade on dictated spelling and recognition of word-specific spellings among phonological foils. In Study 2 new groups received either a second year of manuscript ( N = 29, M = 7 years 8 months, 16 girls) or introduction to cursive (joined) instruction in second grade ( N = 24, M = 8 years 0 months, 11 girls) embedded in the Slingerland literacy program. ANCOVA with automatic alphabet writing as covariate showed that those who received a second year of manuscript handwriting instruction improved more on sustained handwriting over 30, 60, and 90 seconds than those who had had only one year of manuscript instruction; both groups improved in spelling and composing from the second to ninth month of second grade. Results are discussed in reference to mastering one handwriting format before introducing another format at a higher grade level and always embedding handwriting instruction in writing and reading instruction aimed at all levels of language.

In Study 2 new groups received either a second year of manuscript (N = 29, M = 7 years 8 months, 16 girls) or introduction to cursive (joined) instruction in second grade (N = 24, M = 8 years 0 months, 11 girls) embedded in the Slingerland literacy program. ANCOVA with automatic alphabet writing as covariate showed that those who received a second year of manuscript handwriting instruction improved more on sustained handwriting over 30, 60, and 90 seconds than those who had had only one year of manuscript instruction; both groups improved in spelling and composing from the second to ninth month of second grade. Results are discussed in reference to mastering one handwriting format before introducing another format at a higher grade level and always embedding handwriting instruction in writing and reading instruction aimed at all levels of language.

regular physical activity has an effect on biological responses in both muscles and organs that, in turn, alter the structure and functions of the brain. Therefore, this study aims at comparing motor (sprint, coordination ability and explosive legs strength skills) and cognitive abilities (working memory, attention, executive functioning) in children. 39 children with average chronological age of 9 years were divided in: Karatekas (n=19) and Sedentary (n=20) groups. Their abilities were measured by motor and cognitive tests. Motor skills were assessed through a battery composed by the 20 mt Sprint test, the Agility test and the Standing board jump Test. Cognitive profile was assessed by a battery of tests derived from BVN 5-11, "Batteria di Valutazione Neuropsicologica per l'Et à Evolutiva": Visual discrimination test, Reaction time test, Forwards and Backwards Digit Span Tests, Corsi Block-Tapping test and Tower of London. our results reveal significant differences between two groups (p < 0.05). Karate children show better speed times, explosive legs strength and coordination skills. They scored better on working memory, visual selective attention and executive functions. karate exercise training shows global benefits resulting in physiological and psychological gains in children.

Here we describe a semester-long, multipart activity called “Read and wRite to reveal the Research process” (R3) that was designed to teach students the elements of a scientific research paper. We implemented R3 in an advanced immunology course. In R3, we paralleled the activities of reading, discussion, and presentation of relevant immunology work from primary research papers with student writing, discussion, and presentation of their own lab findings. We used reading, discussing, and writing activities to introduce students to the rationale for basic components of a scientific research paper, the method of composing a scientific paper, and the applications of course content to scientific research. As a final part of R3, students worked collaboratively to construct a Group Research Paper that reported on a hypothesis-driven research project, followed by a peer review activity that mimicked the last stage of the scientific publishing process. Assessment of student learning revealed a statistically significant gain in student performance on writing in the style of a research paper from the start of the semester to the end of the semester.

Public health action on a territory is complex and requires the involvement of multiple actors, who do not always act coordinately. Networks of organizations structures including the whole of the local actors facilitate the generation of synergies and enable greater effectiveness and efficiency of the joint action from the different actors on a same landscape. We present 3 years experience of four Public Health Committees in a region of Catalonia (Spain), composed by the main actors in public health planning. Each of the committees is organized on a plenary and working groups on issues arising from the regional health diagnosis, and coincident with the Health Plan of the Region. Coordination in no case implies the loss or dilution of the firm of the actor generator of intervention initiative in public health, but their empowerment and collaboration by the other actors. In conclusion welcomes the creation of a culture of collaboration and synergies between the different organizations concerned. Lack of specificity is observed in establishing operational objectives, and the need for greater coordination and involvement of the components of the various working groups. Copyright © 2012 SESPAS.

Weber, Gary A.

1991-01-01

The Space Transfer Vehicle (STV) program provides both an opportunity and a requirement to increase our upper stage capabilities with the development and applications of new technologies. Issues such as man rating, space basing, reusability, and long lunar surface storage times drive the need for new technology developments and applications. In addition, satisfaction of mission requirements such as lunar cargo delivery capability and lunar landing either require new technology development or can be achieved in a more cost-effective manner with judicious applications of advanced technology. During the STV study, advanced technology development requirements and plans have been addressed by the Technology/Advanced Development Working Group composed of NASA and contractor representatives. This report discusses the results to date of this working group. The first section gives an overview of the technologies that have potential or required applications for the STV and identifies those technologies baselined for the STV. Figures are provided that list the technology categories and show the priority placed on those technology categories for either the space-based or ground-based options. The second section covers the plans and schedules for incorporating the technologies into the STV program.

To describe the food intake of garbage collectors, who works in three shifts, in terms of meal and snack frequency, content, time distribution and the contribution of various popular foods to the total diet. Sixty-six Brazilian garbage collectors, who work in morning, afternoon, and night shift, participated in the present study. The quantitative methods used were a combination of one 24-h recall and two 24-h records during three nonconsecutive work days. The qualitative method used was the food-based classification of eating episodes model modified in order to define meals or snacks in three categories of events: meals with three food groups of high nutrient density (three HND meals), meals with two food groups of high nutrient density (two HND meals) and snacks, composed of only one food category of high nutrient density. The total number of eating events per day was significantly higher for night shift workers. Over 24-h, 'two HND meals' were the most common events and contributed the most energy, in all three shifts. Night shift workers ate more at dawn and less in the morning than other shifts. In all three shifts, meat was the most important food contributing to energy intake. Different work schedules did not affect the relative frequency of meal types and snacks or their contribution to daily energy intake, but affected the daily distribution of eating events, with a redistribution of intake from day to night in night shift workers.

Introduction: The productivity of healthcare staff is one of the main issues for health managers. This study explores the concept of executive regulation of Productivity Improvement Act of clinical staff in health. Methods: In this study phenomenological methodology has been employed. The data were collected through semi-structured interviews and focus group composed of 10 hospital experts and experts in human resources department working in headquarter of Mashhad University of Medical Sciences and 16 nursing managers working in public and private hospitals of Mashhad using purposive sampling. Findings were analyzed using Colaizzi’s seven step method. Results: The strengths of this Act included increasing spirit of hope in nurses, paying attention to quality of nursing care and decreasing problems related to the work plan development. Some of the weaknesses of Productivity Improvement Act included lack of required executive mechanisms, lack of considering nursing productivity indicator, increasing non-public hospitals problems, discrimination between employees, and removal of resting on night shifts. Suggestions were introduced to strengthen the Act such as increased organizational posts, use of a coefficient for wage in unusual work shifts and consideration of a performance indicator. Conclusion: The results may be used as a proper tool for long term management planning at organization level. Finally, if high quality care by health system staff is expected, in the first step, we should take care of them through proper policy making and focusing on occupational characteristics of the target group so that it does not result in discrimination among the staff.

In fatal pursuit of immortal fame: Peer competition and early mortality of music composers.

Borowiecki, Karol Jan; Kavetsos, Georgios

2015-06-01

We investigate the impact of peer competition on longevity using a unique historical data set of 144 prominent music composers born in the 19th century. We approximate for peer competition measuring (a) the number or (b) the share of composers located in the same area and time, (c) the time spent in one of the main cities for classical music, and (d) the quality of fellow composers. These measures suggest that composers' longevity is reduced, if they located in agglomerations with a larger group of peers or of a higher quality. The point estimates imply that, all else equal, a one percent increase in the number of composers reduces composer longevity by ∼ 7.2 weeks. Our analysis showed that the utilized concentration measures are stronger than the personal factors in determining longevity, indicating that individuals' backgrounds have minimal impact on mitigating the effect of experienced peer pressure. The negative externality of peer competition is experienced in all cities, fairly independent of their population size. Our results are reaffirmed using an instrumental variable approach and are consistent throughout a range of robustness tests. In addition to the widely known economic benefits associated with competition, these findings suggest that significant negative welfare externalities exist as well. Copyright © 2015 Elsevier Ltd.

To explore students' attitude towards problem-based learning, creativity and critical thinking, and the relevance to nursing education and clinical practice. Critical thinking and creativity are crucial in nursing education. The teaching approach of problem-based learning can help to reduce the difficulties of nurturing problem-solving skills. However, there is little in the literature on how to improve the effectiveness of a problem-based learning lesson by designing appropriate and innovative activities such as composing songs, writing poems and using role plays. Exploratory qualitative study. A sample of 100 students participated in seven semi-structured focus groups, of which two were innovative groups and five were standard groups, adopting three activities in problem-based learning, namely composing songs, writing poems and performing role plays. The data were analysed using thematic analysis. There are three themes extracted from the conversations: 'students' perceptions of problem-based learning', 'students' perceptions of creative thinking' and 'students' perceptions of critical thinking'. Participants generally agreed that critical thinking is more important than creativity in problem-based learning and clinical practice. Participants in the innovative groups perceived a significantly closer relationship between critical thinking and nursing care, and between creativity and nursing care than the standard groups. Both standard and innovative groups agreed that problem-based learning could significantly increase their critical thinking and problem-solving skills. Further, by composing songs, writing poems and using role plays, the innovative groups had significantly increased their awareness of the relationship among critical thinking, creativity and nursing care. Nursing educators should include more types of creative activities than it often does in conventional problem-based learning classes. The results could help nurse educators design an appropriate curriculum for preparing professional and ethical nurses for future clinical practice. © 2013 Blackwell Publishing Ltd.

A collaborative approach to communicating our amazing science. RAL Space at the Rutherford Appleton Lab, has initiated a unique collaboration with a team of award-winning performing artists with the aim of making space science research engaging and accessible to a wide audience. The collaboration has two distinct but connected strands one of which is the development of a contemporary dance work inspired by solar science and including images and data from the Space Physics Division of STFC RAL Space. The work has been commissioned by Sadler's Wells, one of the world's leading dance venues. It will be created by choreographer Alexander Whitley, video artist Tal Rosner and composers Ella Spira and Joel Cadbury and toured throughout the UK and internationally by the Alexander Whitley Dance Company (AWDC). The work will come about through collaboration with the work of the scientists of RAL Space and in particular the SOHO, CDS and STEREO missions, taking a particular interest in space weather. Choreographer Alexander Whitley and composers Ella Spira and Joel Cadbury will take their inspiration from the images and data that are produced by the solar science within RAL Space. Video artist Tal Rosner will use these spectacular images to create an atmospheric backdrop to accompany the work, bringing the beauty and wonder of space exploration to new audiences. Funding for the creation and touring of the work will be sought from Arts Council England, the British Council, partner organisations, trusts and foundations and private donors.The world premiere of the work will take place at Sadler's Wells in June 2017. It will then tour throughout the UK and internationally to theatres, science conferences and outreach venues with the aim of bringing the work of STFC RAL Space and the science behind solar science and space weather to new audiences. An education programme will combine concepts of choreography and space science aimed at young people in year 5 Key Stage 2 and be developed by a Creative Learning specialist with input from RAL Space scientists and engineers, the RAL Space communication and outreach group and Alexander Whitley Dance Company. The programme will be piloted in selected East London schools and then, following evaluation, be rolled out to several schools across the UK.

In this work, we developed a unique mathematical model to solve dispersion relation for surface polaritons (SPs) in artificial composite materials grating. Here, we have taken two types of materials for analysis. In the first case, the grating composed of epsilon-negative (ENG) material and air interface. In second case, grating composed of left-handed materials (LHMs) and ENG medium interface is considered. The dispersion curves of both p and s polarized SPs modes are obtained analytically. In the case of ENG grating and air interface, polaritons dispersion curves exist for p-polarization only, whereas for LHM grating and ENG medium interface, the polaritons dispersion curves for both p and s polarization are observed.

Lethal violence and psychosis: a clinical profile.

Nestor, P G; Haycock, J; Doiron, S; Kelly, J; Kelly, D

1995-01-01

To investigate the relationship between lethal violence and psychosis, the authors examined symptomatology, neuropsychological functioning, and the nature of perpetrator-victim relationships of patients with psychotic disorders who were committed to a forensic psychiatric hospital following violent, primarily criminal behavior. A severely violent group, composed primarily of psychotic patients charged with murder, was compared with a less severely violent group that was composed primarily of psychotic patients involved with property crimes. As compared with the less violent group, the severely violent group was more likely to have delusional beliefs about specific personal targets and to have delusions about significant others being replaced by impostors. These beliefs were accompanied by higher scores on neuropsychological tests of intellectual and academic abilities. A high number of their blood relatives were victims of psychotic murder. These results indicated that a higher incidence of lethal or near lethal acts of violence may characterize intellectually intact but psychotic individuals with organize delusions involving personal, accessible targets.

Frequency Analysis of the Laser Biospeckle

2008-04-01

This research work presents a study of beans seed tissue (Phaseolous vulgaris, L.) optical interactions with laser aiming to contribute to the development of biospeckle techniques applied to the recognition of bean seed tissue vitality when contaminated with fungi, by differentiating the generated frequency spectra. Biospeckle is an interference optic phenomenon occurring when a laser beam reaches a surface exhibiting some dynamic process, due to biological activities or purely physical changes. The technique involves image processing to distinguish each different active material contribution present in the seed, by means of the procedure known as "Moment of Inertia" and frequency analysis. Frequency analysis was carried by Fourier Transform preceded by module of convolution. A great challenge in this area is to identify the elements contribution to increase biospeckle activity, such as water, microorganisms, among others. This research work is recognized to provide an important step aiming to characterize the interaction of laser with biological material. Three groups of bean seeds were employed, one represented by healthy seeds and two groups composed of seeds contaminated with Aspergillus spp as well as with Fusarium spp fungi. The biospeckle analysis considered the activity and its frequency spectra. The seeds were each one exposed to laser in a random order. The results reveled differences in the average values of MI of the three seed groups. Also, some different harmonics in the biospeckle pattern in a same group as well as among seed groups had been noticed. These results allow confirming that it is possible to differentiate contaminated seeds from non-contaminated ones by means of biospeckle frequency analysis.

'Ain't nothin' like the real thing'. Motivation and study processes on a work-based project course in information systems design.

2007-06-01

Advocates of the project method claim that project-based learning inspires student learning. However, it has been claimed that project-based learning environments demand quite a bit of self-regulation on the part of the learner. Consequently, it was tested whether students scoring low in self-regulation of learning experienced 'friction', an incompatibility between student self-regulation and the demands posed by the learning environment. This would be manifest in cognitive processing and motivation. The target group consisted of 58 mainly third-year Finnish university students taking a mandatory project course in information systems design. During the project course, student teams completed a commissioned assignment. The study also included a matched nonequivalent comparison group composed of computer science students attending study programmes without a project-based component. Data were gathered by means of a questionnaire administered at the beginning and end of the project course and it was analysed by between-groups repeated measures ANOVA. In addition, the students on the course were interviewed. Results suggest that the work-based project model in question may indeed have a substantial motivational impact, interestingly benefitting especially those students who scored low in self-regulation. It is argued that we tend to view learning environments too simplistically. In particular, a basic distinction should be made between individual and collaborative learning contexts, since peer scaffolding, group grading and choice of group roles may explain why students scoring low in self-regulation of learning did not encounter friction as expected.

A total of 75 participants were divided into two groups: Group 1 (n = 40) was composed of healthy postmenopausal women, and group 2 (n = 35) was composed of women with postmenopausal osteoporosis. Clinical findings and thiol/disulfide homeostasis were compared between the two groups. The disulfide/native thiol ratio was 8.6% ± 3.6 in group 1 and 12.7% ± 8.4 in group 2 (p = 0.04). The disulfide/native thiol percent ratio was significantly higher in group 2 after adjustment for the years since menopause and age (p < 0.05). The native thiol/total thiol percent ratio was 85.6% ± 4.8 in group 1 and 73.8% ± 24.9 in group 2 (p = 0.01). The native thiol/total thiol percent ratio was significantly lower in group 2 after adjustment for the years since menopause and age (p < 0.05). Thiol/disulfide homeostasis shifted to the disulfide side independent of age and years since menopause in postmenopausal osteoporosis.

to identify sensitivity alteration in the intercostal brachial nerve pathway using an extensiometer, and to observe the measurement reproducibility of the apparatus. the Semmes-Weinstein extensiometer was used to evaluate the sensitivity along the intercostal brachial nerve pathway. Ninety-four women have participated in the study, divided into two groups: a CA Group composed of 47 women submitted to breast cancer axillary lymphadenectomy, and a comparative group composed of 47 women without breast cancer, who had not been submitted to any kind of axillary surgery. Each participant underwent anamnesis and two consecutive applications of the extensiometer. The Control Group responses to the extensiometer test were used as normality reference values. based on Control Group responses, the prevalence of sensitivity changes was 85.1% in the CA Group. Reproducibility of the extensiometer application was confirmed in the CA Group through the Kappa's test (p=0.8). in this studied sample, sensitivity alterations had high prevalence; evaluations made with the extensiometer were reproducible, and thus we consider the equipment reliable to evaluate sensitivity along the intercostal brachial nerve pathway.

Life expectancy for people with severe mental disorders is up to 25 years less in comparison to the general population, mainly due to diseases caused or worsened by smoking. However, smoking is usually a neglected issue in mental healthcare settings. The aim of this article is to describe a strategy to improve tobacco control in the hospital mental healthcare services of Catalonia (Spain). To bridge this gap, the Catalan Network of Smoke-free Hospitals launched a nationwide bottom-up strategy in Catalonia in 2007. The strategy relied on the creation of a working group of key professionals from various hospitals -the early adopters- based on Rogers' theory of the Diffusion of Innovations. In 2016, the working group is composed of professionals from 17 hospitals (70.8% of all hospitals in the region with mental health inpatient units). Since 2007, tobacco control has improved in different areas such as increasing mental health professionals' awareness of smoking, training professionals on smoking cessation interventions and achieving good compliance with the national smoking ban. The working group has produced and disseminated various materials, including clinical practice and best practice guidelines, implemented smoking cessation programmes and organised seminars and training sessions on smoking cessation measures in patients with mental illnesses. The next challenge is to ensure effective follow-up for smoking cessation after discharge. While some areas of tobacco control within these services still require significant improvement, the aforementioned initiative promotes successful tobacco control in these settings.

Development of the Practical Solutions for Pesticide Safety guide used participatory research strategies to identify and evaluate solutions that reduce pesticide exposures for workers and their families and to disseminate these solutions. Project principles were (1) workplace chemicals belong in the workplace, and (2) pesticide handlers and farm managers are experts, with direct knowledge of production practices. The project’s participatory methods were grounded in self-determination theory. Practical solutions were identified and evaluated based on five criteria: practicality, adaptability, health and safety, novelty, and regulatory compliance. Research activities that had more personal contact provided better outcomes. The Expert Working Group, composed of farm managers and pesticide handlers, was key to the identification of solutions, as were farm site visits. Audience participation, hands-on testing, and orchard field trials were particularly effective in the evaluation of potential solutions. Small work groups in a Regional Advisory Committee provided the best direction and guidance for a “user-friendly” translational document that provided evidence-based practical solutions. The “farmer to farmer” format of the guide was endorsed by both the Expert Working Group and the Regional Advisory Committee. Managers and pesticide handlers wanted to share their solutions in order to “help others stay safe,” and they appreciated attribution in the guide. The guide is now being used in educational programs across the region. The fundamental concept that farmers and farmworkers are innovators and experts in agricultural production was affirmed by this study. The success of this process demonstrates the value of participatory industrial hygiene in agriculture. PMID:26488540

Zhang, Liying; Li, Haolong; Wu, Lixin

2014-09-21

The block copolymers (BCs), as structure-directing agents, co-assembling with nanoscale inorganic additives is an important route to fabricate nanostructured hybrid materials. In this work, we present a facile approach to fabricate hybrid micelles composed of BCs and polyoxometalates (POMs), in which the POM clusters are premodified with the groups that can specifically interact with a certain BC block. A representative POM (NH4)42[Mo(132)O(372)(CH(3)COO)(30)(H2O)72] (Mo(132)) is chosen as the example and encapsulated with cationic molecules containing carboxyphenyl groups through electrostatic interactions, and then the resulting hybrid complex can further co-assemble with poly(styrene-block-4-vinylpyridine) (PS-b-P4VP) through hydrogen bonding with the pyridine groups, which leads to the formation of hybrid micelles and the localization of Mo(132) in the micelle cores. The micelles exhibit a high stability despite time and dilution. Furthermore, the fusion of the micelles can be readily adjusted by varying the length of PS blocks, which is promising to be used in constructing polymer-POM hybrid materials with discrete or continuous hybrid domains. This work is based on the electrostatic premodification of POMs and thus its concept is generally suitable for the whole anionic POM system, which may create a large class of BC-POM nanocomposites with tunable structures.

Band structure analysis of a thin plate with periodic arrangements of slender beams

Serrano, Ó.; Zaera, R.; Fernández-Sáez, J.

2018-04-01

This work analyzes the wave propagation in structures composed of a periodic arrangement of vertical beams rigidly joined to a plate substrate. Three different configurations for the distribution of the beams have been analyzed: square, triangular, and hexagonal. A dimensional analysis of the problem indicates the presence of three dimensionless groups of parameters controlling the response of the system. The main features of the wave propagation have been found using numerical procedures based on the Finite Element Method, through the application of the Bloch's theorem for the corresponding primitive unit cells. Illustrative examples of the effect of the different dimensionless parameters on the dynamic behavior of the system are presented, providing information relevant for design.

Choubey, Vishnu D.; Litoria, Pradeep K.

Terrain classification and land system mapping of a part of the Garhwal Himalaya (India) have been used to provide a base map for land hazard evaluation, with special reference to landslides and other mass movements. The study was based on MSS images, aerial photographs and 1:50,000 scale maps, followed by detailed field-work. The area is composed of two groups of rocks: well exposed sedimentary Precambrian formations in the Himalayan Main Boundary Thrust Belt and the Tertiary molasse deposits of the Siwaliks. Major tectonic boundaries were taken as the natural boundaries of land systems. A physiographic terrain classification included slope category, forest cover, occurrence of landslides, seismicity and tectonic activity in the area.

This work arises from the need to investigate the role of motivational variables in homework involvement and academic achievement of elementary school students. The aims of this study are twofold: identifying the different combinations of student academic goals and analyzing the differences in homework involvement and academic achievement. The sample was composed of 535 fourth-, fifth- and sixth-grade elementary school students, between the ages of 9 and 13 years old. Findings showed three groups with different motivational profiles: a group of students with high multiple goals, another group with a learning goal orientation and a third group defined by a low multiple goals profile. Focusing on the differences between groups, it was observed that the amount of time doing homework was not associated with any motivational profile. Nevertheless, the differences were statistically significant between the motivational groups in the amount of homework (F(2, 530) = 42.59; p < .001; ηp 2 = .138), in the management of time spent on homework (F(2, 530) = 33.08; p < .001; ηp 2 = .111), and in academic achievement (F(2, 530) = 33.99; p < .001; ηp 2 = .114). The effect size was large for the amount of homework performed and was also relatively large in the case of management of time and academic achievement.

In this study we evaluate the efficacy of five vaccine formulations containing different combinations of proteins (FimH; leukotoxin, LKT; and pyolysin, PLO) and/or inactivated whole cells (Escherichia coli, Fusobacterium necrophorum, and Trueperella pyogenes) in preventing postpartum uterine diseases. Inactivated whole cells were produced using two genetically distinct strains of each bacterial species (E. coli, F. necrophorum, and T. pyogenes). FimH and PLO subunits were produced using recombinant protein expression, and LKT was recovered from culturing a wild F. necrophorum strain. Three subcutaneous vaccines were formulated: Vaccine 1 was composed of inactivated bacterial whole cells and proteins; Vaccine 2 was composed of proteins only; and Vaccine 3 was composed of inactivated bacterial whole cells only. Two intravaginal vaccines were formulated: Vaccine 4 was composed of inactivated bacterial whole cells and proteins; and Vaccine 5 was composed of PLO and LKT. To evaluate vaccine efficacy, a randomized clinical trial was conducted at a commercial dairy farm; 371 spring heifers were allocated randomly into one of six different treatments groups: control, Vaccine 1, Vaccine 2, Vaccine 3, Vaccine 4 and Vaccine 5. Late pregnant heifers assigned to one of the vaccine groups were each vaccinated twice: at 230 and 260 days of pregnancy. When vaccines were evaluated grouped as subcutaneous and intravaginal, the subcutaneous ones were found to significantly reduce the incidence of puerperal metritis. Additionally, subcutaneous vaccination significantly reduced rectal temperature at 6±1 days in milk. Reproduction was improved for cows that received subcutaneous vaccines. In general, vaccination induced a significant increase in serum IgG titers against all antigens, with subcutaneous vaccination again being more effective. In conclusion, subcutaneous vaccination with inactivated bacterial components and/or protein subunits of E. coli, F. necrophorum and T. pyogenes can prevent puerperal metritis during the first lactation of dairy cows, leading to improved reproduction.

Assessing AIDS/HIV prevention: what do we know in Europe?

An EC concerted action on the assessment of AIDS/HIV prevention strategies was conducted between 1989 and 1992. The aim of this concerted action (CA) was to bring together researchers who are active in this assessment field, make an initial appraisal of the results of AIDS prevention efforts, in various population groups in Europe and develop an assessment methodology. Five areas of study were selected for the CA: the population as a whole ("general population"), men who have sexual relations with other men, intravenous drug users, migrant populations, monitoring of sexually transmitted diseases (STDs) to determine changes in behaviour. For each of these areas, a working group composed of the leading researchers in the field in Europe was constituted and commissioned by the project administration and coordination team to collate and analyse data on prevention efforts and their assessment in different countries of Europe. This review presents the main results from the groups responsible in each area in the concerted action. A number of general conclusions from the results of this concerted action are drawn.

Determining problems experienced by student nurses in their work with clinical educators in Turkey.

Clinical education is considered an indispensable and vital part of nursing education. Educators have an important role in the successful completion of a student's clinical education. The clinical educator's approach, experience and knowledge have an influence on the students. Students encounter certain problems during their clinical practice under the supervision of educators. This study was conducted to determine the nature of the problems student nurses encounter during clinical training in Turkey. The focus-group interviews were used for this study. Three groups of 8, a total group of 24, composed of students completing their third year were included in the interviews. The students in this study had completed their practical training in the departments of internal medicine, surgery, pediatrics, psychiatry and public health. Among the problems mostly encountered by students, as established by the study, were inadequate assessment by the clinical educator, judgment, negative feedback, communication problems, inadequate guidance and overload. At the end of the research, recommendations were that educators should offer information in the direction of student expectations, increase their positive feedback and lighten the academic workload of these students.

To find whether agricultural workers seen in the general medical clinic attend due to symptoms connected with the use of pesticides. A crossover descriptive study comparing agricultural workers with a control group. Primary care. The clinical histories of 40 agricultural workers and a control group (sample of 58 paired for age and gender) who had been seen over the previous year. Age, gender, frequency of attendance, motives for consultation, risk factors and the number of consultations for symptoms possibly due to exposure to pesticides--in line with a previously composed list. There were no differences in frequency of attendance, overall reasons for consultation or risk factors. It was seen that agricultural workers consulted 4 times more than the control group for suspected pesticide poisoning (p = 0.0015). In our health area agricultural workers present symptoms which should probably be attributed to insufficient protection against pesticides. The primary care doctor working in rural zones where these products are heavily used must be able to identify these symptoms and take appropriate measures.

Visiting Vehicle Ground Trajectory Tool

Hamm, Dustin

2013-01-01

The International Space Station (ISS) Visiting Vehicle Group needed a targeting tool for vehicles that rendezvous with the ISS. The Visiting Vehicle Ground Trajectory targeting tool provides the ability to perform both realtime and planning operations for the Visiting Vehicle Group. This tool provides a highly reconfigurable base, which allows the Visiting Vehicle Group to perform their work. The application is composed of a telemetry processing function, a relative motion function, a targeting function, a vector view, and 2D/3D world map type graphics. The software tool provides the ability to plan a rendezvous trajectory for vehicles that visit the ISS. It models these relative trajectories using planned and realtime data from the vehicle. The tool monitors ongoing rendezvous trajectory relative motion, and ensures visiting vehicles stay within agreed corridors. The software provides the ability to update or re-plan a rendezvous to support contingency operations. Adding new parameters and incorporating them into the system was previously not available on-the-fly. If an unanticipated capability wasn't discovered until the vehicle was flying, there was no way to update things.

SSI rates after gynecologic oncology surgery vary from 5% to 35%, but are up to 45% in patients with diabetes mellitus (DM). Strict postoperative glucose control by insulin infusion has been shown to lower morbidity, but not specifically SSI rates. Our project studied continuous postoperative insulin infusion for 24h for gynecologic oncology patients with DM and hyperglycemia with a target blood glucose of <139 mL/dL and a primary outcome of the protocol's impact on SSI rates. We compared SSI rates retrospectively among three groups. Group 1 was composed of patients with DM whose blood glucose was controlled with intermittent subcutaneous insulin injections. Group 2 was composed of patients with DM and postoperative hyperglycemia whose blood glucose was controlled by insulin infusion. Group 3 was composed of patients with neither DM nor hyperglycemia. We controlled for all relevant factors associated with SSI. We studied a total of 372 patients. Patients in Group 2 had an SSI rate of 26/135 (19%), similar to patients in Group 3 whose rate was 19/89 (21%). Both were significantly lower than the SSI rate (43/148, 29%) of patients in Group 1. This reduction of 35% is significant (p = 0.02). Multivariate analysis showed an odd ratio = 0.5 (0.28-0.91) in reducing SSI rates after instituting this protocol. Initiating intensive glycemic control for 24h after gynecologic oncology surgery in patients with DM and postoperative hyperglycemia lowers the SSI rate by 35% (OR = 0.5) compared to patients receiving intermittent sliding scale insulin and to a rate equivalent to non-diabetics.

Wick, Raymond V.

2005-04-01

The Department of Defense (DoD) Militarily Critical Technologies Program (MCTP) provides a systematic, ongoing assessment and analysis of goods and technologies to determine those that would permit significant advances in the development, production and use of military capabilities of potential adversaries and those that are being developed worldwide that have the potential to significantly enhance or degrade US military capabilities in the future. The program's objective is to characterize the technologies, including quantitative values and parameters, and assess worldwide technology capabilities. The MCTP is composed of two sets of documents, the well known and often referenced one, the MCTL, and a second one, a more recently added list called the Developing Science and Technologies List (DSTL). Both are products of the MCTP process, however, the later is primarily used by DDR&E and other government organizations and agencies to aid in the prioritization and understanding of new technologies being developed worldwide. Technologies are selected for the MCTL and the DSTL through the deliberation and consensus of Technology Working Groups (TWGs). TWGs continually screen technologies and nominate items to be added or removed from the MCTL and the DSTL as appropriate. Working within an informal structure, TWG members are composed of government, industry and academia subject matter experts, who strive to produce precise and objective analyses across each technology areas. This process and details of the current MCTP are outlined in this poster paper. This paper focuses on the solid state laser technology area, using it as an example of the MCTP's product of assessing, identifying, and quantifying militarily critical technology parameters.

This study attempts to formulate a prediction model of return to work for a group of workers who have been suffering from chronic pain and physical injury while also being out of work in Hong Kong. The study used Case-based Reasoning (CBR) method, and compared the result with the statistical method of logistic regression model. The database of the algorithm of CBR was composed of 67 cases who were also used in the logistic regression model. The testing cases were 32 participants who had a similar background and characteristics to those in the database. The methods of setting constraints and Euclidean distance metric were used in CBR to search the closest cases to the trial case based on the matrix. The usefulness of the algorithm was tested on 32 new participants, and the accuracy of predicting return to work outcomes was 62.5%, which was no better than the 71.2% accuracy derived from the logistic regression model. The results of the study would enable us to have a better understanding of the CBR applied in the field of occupational rehabilitation by comparing with the conventional regression analysis. The findings would also shed light on the development of relevant interventions for the return-to-work process of these workers.

Equitable partnership processes and group dynamics, including individual, relational, and structural factors, have been identified as key ingredients to successful community-based participatory research partnerships. The purpose of this qualitative study was to investigate the key aspects of group dynamics and partnership from the perspectives of community members serving as co-researchers. Semistructured, in-depth interviews were conducted with 15 Latino immigrant co-researchers from an intervention project with Latinos Unidos por la Salud (LU-Salud), a community research team composed of Latino immigrant community members and academic investigators working in a health research partnership. A deductive framework approach guided the interview process and qualitative data analysis. The LU-Salud co-researchers described relationships, personal growth, beliefs/identity motivation (individual dynamics), coexistence (relational dynamics), diversity, and power/resource sharing (structural dynamics) as key foundational aspects of the community-academic partnership. Building on existing CBPR and team science frameworks, these findings demonstrate that group dynamics and partnership processes are fundamental drivers of individual-level motivation and meaning making, which ultimately sustain efforts of community partners to engage with the research team and also contribute to the achievement of intended research outcomes.

Currently, Service-Oriented Architecture (SOA) is becoming the most popular software architecture of contemporary enterprise applications, and one crucial technique of its implementation is web services. Individual service offered by some service providers may symbolize limited business functionality; however, by composing individual services from different service providers, a composite service describing the intact business process of an enterprise can be made. Many new standards have been defined to decipher web service composition problem namely Business Process Execution Language (BPEL). BPEL provides an initial work for forming an Extended Markup Language (XML) specification language for defining and implementing business practice workflows for web services. The problems with most realistic approaches to service composition are the verification of composed web services. It has to depend on formal verification method to ensure the correctness of composed services. A few research works has been carried out in the literature survey for verification of web services for deterministic system. Moreover the existing models did not address the verification properties like dead transition, deadlock, reachability and safetyness. In this paper, a new model to verify the composed web services using Enhanced Stacked Automata Model (ESAM) has been proposed. The correctness properties of the non-deterministic system have been evaluated based on the properties like dead transition, deadlock, safetyness, liveness and reachability. Initially web services are composed using Business Process Execution Language for Web Service (BPEL4WS) and it is converted into ESAM (combination of Muller Automata (MA) and Push Down Automata (PDA)) and it is transformed into Promela language, an input language for Simple ProMeLa Interpreter (SPIN) tool. The model is verified using SPIN tool and the results revealed better recital in terms of finding dead transition and deadlock in contrast to the existing models.

Beyond Mechanism Design

NASA Technical Reports Server (NTRS)

Wolpert, David H.; Turner, Kagan

2004-01-01

The field of mechanism design is concerned with setting (incentives superimposed on) the utility functions of a group of players so as to induce desirable joint behavior of those players. It arose in the context of traditional equilibrium game theory applied to games involving human players. This has led it to have many implicit restrictions, which strongly limits its scope. In particular, it ignores many issues that are crucial for systems that are large (and therefore far off-equilibrium in general) and/or composed of non-human players (e.g., computer-based agents). This also means it has concentrated on issues that are often irrelevant in those broader domains (e.g., incentive compatibility). This paper illustrates these shortcomings by reviewing some of the recent theoretical work on the design of collectives, a body of work that constitutes a substantial broadening of mechanism design. It then presents computer experiments based on a recently suggested nanotechnology testbed that demonstrates the power of that extended version of mechanism design.

To investigate the risk factors that may relate with benign vocal fold lesions including vocal fold nodule, vocal fold polyp, chronic laryngitis and Reinke's edema In present series, 321 cases who were performed laryngoscope were invited to participate the survey. Among them 168 cases with benign vocal fold lesions composed the case group. Another 153 cases with normal larynx composed the control group. Each case were undertook the same questionnaire. Logistic regression analysis was preformed to investigate the possible risk factors. The result demonstrated the occurring of benign vocal fold lesions positively correlated to five factors, including occupation, work or residence environment noise, alcohol-consuming, voice-using hours per day and abuse of voice. Occupations with intensive voice-use were more vulnerable to developing these disorders. Occurring risk of occupations type II with moderate voice-use was 1.934 times than that of occupations type I with lesser voice-use (OR = 1.934). And risk of occupations type III with upper voice-use was 2.633 times than that of type I. Risk raised 1.302 times with each more hour of voice use per day. OR of the following factors of voice abuse, environment noise, alcohol-consuming was 4.744, 2.115 and 2.177, respectively. The result suggested that people should abstain from alcohol, lowering the environment noise, prevent overuse and abuse of voice in order to decrease the prevalence of these disorders, which is especially important for the professional voice users, e. g. teachers or managers. The essential therapy for these disorders is to correct bad phonation habits.

Probing the effects of the ester functional group, alkyl side chain length and anions on the bulk nanostructure of ionic liquids: a computational study.

The effects of ester addition on nanostructural properties of biodegradable ILs composed of 1-alkoxycarbonyl-3-alkyl-imidazolium cations ([C1COOCnC1im](+), n = 1, 2, 4) combined with [Br](-), [NO3](-), [BF4](-), [PF6](-), [TfO](-), and [Tf2N](-) were explored by using the molecular dynamics (MD) simulations and quantum theory of atoms in molecules (QTAIM) analysis at 400 K. Various thermodynamic properties of these ILs were extensively computed in our earlier work (Ind. Eng. Chem. Res., 2015, 54, 11678-11700). Nano-scale segregation analysis demonstrates the formation of a small spherical island-like hydrocarbon within the continuous ionic domain for ILs with short alkyl side chain ([C1COOC1C1im]), and a sponge-like nanostructure for the compound with long alkyl side chain ([C1COOC4C1im]). Ester-functionalized ILs with ethyl side chain ([C1COOC2C1im]) are the turning point between two different morphologies. Non-polar channels were observed for [C1COOC4C1im] ILs composed of smaller anions such as [Br] and [NO3], whereas clustering organization was found for the other anions. Formation of the spherical micelle-like nanostructure was seen for lengthened cations. Finally, the incorporation of an ester group into the alkyl side chain of the cation leads to stronger segregation between charged and uncharged networks, which consequently increased the possibility of self-assembly and micelle formation.

Adjacent bin stability evaluating for feature description

NASA Astrophysics Data System (ADS)

Nie, Dongdong; Ma, Qinyong

2018-04-01

Recent study improves descriptor performance by accumulating stability votes for all scale pairs to compose the local descriptor. We argue that the stability of a bin depends on the differences across adjacent pairs more than the differences across all scale pairs, and a new local descriptor is composed based on the hypothesis. A series of SIFT descriptors are extracted from multiple scales firstly. Then the difference value of the bin across adjacent scales is calculated, and the stability value of a bin is calculated based on it and accumulated to compose the final descriptor. The performance of the proposed method is evaluated with two popular matching datasets, and compared with other state-of-the-art works. Experimental results show that the proposed method performs satisfactorily.

1978-01-01

The results obtained by Consolmagno (1975) with regard to the interiors of the smaller icy satellites are presented and the evolution of the surfaces of these objects in the light of the considered models is discussed. In the discussion the icy satellites are divided into two groups. Those with radii larger than 1000 km are composed primarily of high-pressure phases of ice. In the case of satellites of this group, internal heating may produce significant melting and solid-state convection may not be important. Those satellites with radii less than 1000 km will be composed primarily of ice I and rock. They will not significantly melt and internal convection is likely to be important.

When group membership gets personal: a theory of identity fusion.

PubMed

Swann, William B; Jetten, Jolanda; Gómez, Angel; Whitehouse, Harvey; Bastian, Brock

2012-07-01

Identity fusion is a relatively unexplored form of alignment with groups that entails a visceral feeling of oneness with the group. This feeling is associated with unusually porous, highly permeable borders between the personal and social self. These porous borders encourage people to channel their personal agency into group behavior, raising the possibility that the personal and social self will combine synergistically to motivate pro-group behavior. Furthermore, the strong personal as well as social identities possessed by highly fused persons cause them to recognize other group members not merely as members of the group but also as unique individuals, prompting the development of strong relational as well as collective ties within the group. In local fusion, people develop relational ties to members of relatively small groups (e.g., families or work teams) with whom they have personal relationships. In extended fusion, people project relational ties onto relatively large collectives composed of many individuals with whom they may have no personal relationships. The research literature indicates that measures of fusion are exceptionally strong predictors of extreme pro-group behavior. Moreover, fusion effects are amplified by augmenting individual agency, either directly (by increasing physiological arousal) or indirectly (by activating personal or social identities). The effects of fusion on pro-group actions are mediated by perceptions of arousal and invulnerability. Possible causes of identity fusion--ranging from relatively distal, evolutionary, and cultural influences to more proximal, contextual influences--are discussed. Finally, implications and future directions are considered. Copyright 2012 APA, all rights reserved.

Computer scientist Luc Steels uses artificial intelligence to explore the origins and evolution of language. He is best known for his 1999-2001 Talking Heads Experiment, in which robots had to construct a language from scratch to communicate with each other. Now Steels, who works at the Free University of Brussels (VUB), has composed an opera based on the legend of Faust, with a twenty-first-century twist. He talks about Mozart as a nascent computer programmer, how music maps onto language, and the blurred boundaries of a digitized world.

Narrative reflective practice in medical education for residents: composing shifting identities

PubMed Central

Clandinin, Jean; Cave, Marie Thérèse; Cave, Andrew

2011-01-01

As researchers note, medical educators need to create situations to work with physicians in training to help them attend to the development of their professional identities. While there is a call for such changes to be included in medical education, educational approaches that facilitate attention to the development of medical students’ professional identities, that is, who they are and who they are becoming as physicians, are still under development. One pedagogical strategy involves narrative reflective practice as a way to develop physician identity. Using this approach, medical residents first write narrative accounts of their experiences with patients in what are called “parallel charts”. They then engage in a collaborative narrative inquiry within a sustained inquiry group of other residents and two researcher/facilitators (one physician, one narrative researcher). Preliminary studies of this approach are underway. Drawing on the experiences of one medical resident in one such inquiry group, we show how this pedagogical strategy enables attending to physician identity making. PMID:23745070

A group of 47 patients diagnosed with neurodevelopmental disorders were compared to 47 age-, gender-, and racially matched typically developing children to examine the frequency of impairment across domains of the Mullen Scales of Early Learning (MSEL). The MSEL is a comprehensive measure of cognitive functioning designed to assess infants and preschool children between the ages of birth to 68 months. In the neurodevelopmental group, the sample was composed of children 2 to 4 years of age who were diagnosed with autism spectrum disorders (ASD; n = 19), cerebral palsy (CP; n = 14), and epilepsy (EPI; n = 14). A sample of 47 matched controls, taken from the normative sample of the MSEL, was used as a comparison group. Each one of the clinical groups comprising the neurodevelopmental sample demonstrated statistically significant delays across domains relative to the respective matched control group (p < .001). Children failed to demonstrate a "signature" profile for a diagnosis of ASD, CP, or EPI. The clinical sensitivity of the MSEL and the need for obtaining specific intervention services for children diagnosed with these conditions are presented. Finally, these results are discussed within the context of the clinical sensitivity of the MSEL in working with these clinical populations.

The aims of this work were to identify and establish differential characteristics in learning strategies, goal orientations, and self-concept between overachieving, normal-achieving and underachieving secondary students. A total of 1400 Spanish first and second year high school students from the South-East geographical area participated in this study. Three groups of students were established: a group with underachieving students, a group with a normal level of achievement, and a third group with overachieving students. The students were assigned to each group depending on the residual punctuations obtained from a multiple regression analysis in which the punctuation of an IQ test was the predictor and a measure composed of the school grades of nine subjects was the criteria. The results of one-way ANOVA and the Games-Howell post-hoc test showed that underachieving students had significantly lower punctuations in all of the measures of learning strategies and learning goals, as well as all of the academic self-concept, personal self-concept, parental relationship, honesty, and personal stability factors. In contrast, overachieving students had higher punctuations than underachieving students in the same variables and higher punctuations than normal-achieving students in most of the variables in which significant differences were detected. These results have clear educational implications.

Cyclic nitroxides are a large group of compounds composed of diverse stable radicals also known as synthetic antioxidants. Although nitroxides are valuable for use in several skin conditions, in in vivo conditions they have several drawbacks, such as nonspecific dispersion in normal tissue, preferential renal clearance and rapid reduction of the nitroxide to the corresponding hydroxylamine. However, these drawbacks can be easily addressed by encapsulating the nitroxides within microemulsions. This approach would allow nitroxide activity and therefore their valuable effects (e.g. activation of the Keap1-Nrf2-EpRE pathway) to continue. In this work, nitroxides were encapsulated in a microemulsion composed of biocompatible ingredients. The nanometric size and shape of the vehicle microemulsion and nitroxide microemulsion displayed high similarity, indicating that the stability of the microemulsions was preserved. Our studies demonstrated that nitroxide microemulsions were more potent inducers of the Keap1-Nrf2-EpRE pathway than the free nitroxides, causing the activation of phase II enzymes. Moreover, microemulsions containing nitroxides significantly reduced UVB-induced cytotoxicity in the skin. Understanding the mechanism of this improved activity may expand the usage of many other Nrf2 modulating molecules in encapsulated form, as a skin protection strategy against oxidative stress-related conditions.

The aim of this study was to investigate the developmental trajectories of attention, short-term memory, and working memory in school-aged children using a 10 min test battery of cognitive function. Participants comprised 144 typically developing children (TDC) aged 7-12 years and 24 healthy adults, divided according to age into seven groups (12 males and 12 females for each age group). Participants were assessed using CogHealth, which is a computer-based measure composed of five tasks. We measured attention, short-term memory, and working memory (WM) with visual stimulation. Each task was analyzed for age-related differences in reaction time and accuracy rate. Attention tasks were faster in stages from the age of 7-10 years. Accuracy rate of short-term memory gradually increased from 12 years of age and suddenly increased and continued to increase at 22 years of age. Accuracy rate of working memory increased until 12 years of age. Correlations were found between the ages and reaction time, and between ages and accuracy rate of the tasks. These results indicate that there were rapid improvements in attention, short-term memory, and WM performance between 7 and 10 years of age followed by gradual improvement until 12 years of age. Increase in short-term memory continued until 22 years of age. In our experience CogHealth was an easy and useful measure for the evaluation of cognitive function in school-age children.

Galaxy triplets in Sloan Digital Sky Survey Data Release 7 - II. A connection with compact groups?

NASA Astrophysics Data System (ADS)

2013-08-01

We analyse a sample of 71 triplets of luminous galaxies derived from the work of O'Mill et al. We compare the properties of triplets and their members with those of control samples of compact groups, the 10 brightest members of rich clusters and galaxies in pairs. The triplets are restricted to have members with spectroscopic redshifts in the range 0.01 ≤ z ≤ 0.14 and absolute r-band luminosities brighter than Mr = -20.5. For these member galaxies, we analyse the stellar mass content, the star formation rates, the Dn(4000) parameter and (Mg - Mr) colour index. Since galaxies in triplets may finally merge in a single system, we analyse different global properties of these systems. We calculate the probability that the properties of galaxies in triplets are strongly correlated. We also study total star formation activity and global colours, and define the triplet compactness as a measure of the percentage of the system total area that is filled by the light of member galaxies. We concentrate in the comparison of our results with those of compact groups to assess how the triplets are a natural extension of these compact systems. Our analysis suggests that triplet galaxy members behave similarly to compact group members and galaxies in rich clusters. We also find that systems comprising three blue, star-forming, young stellar population galaxies (blue triplets) are most probably real systems and not a chance configuration of interloping galaxies. The same holds for triplets composed of three red, non-star-forming galaxies, showing the correlation of galaxy properties in these systems. From the analysis of the triplet as a whole, we conclude that, at a given total stellar mass content, triplets show a total star formation activity and global colours similar to compact groups. However, blue triplets show a high total star formation activity with a lower stellar mass content. From an analysis of the compactness parameter of the systems we find that light is even more concentrated in triplets than in compact groups. We propose that triplets composed of three luminous galaxies, should not be considered as an analogous of galaxy pairs with a third extra member, but rather they are a natural extension of compact groups.

Facile preparation of well-combined lignin-based carbon/ZnO hybrid composite with excellent photocatalytic activity

2017-12-01

In this work, a novel lignin-based carbon/ZnO (LC/ZnO) hybrid composite with excellent photocatalytic performance was prepared through a convenient and environment friendly method using alkali lignin (AL) as carbon source. The morphological, microstructure and optical properties of the as-prepared LC/ZnO hybrid composite was characterized with scanning electron microscope (SEM), X-ray diffraction (XRD), Raman and UV-vis. The resulting LC/ZnO hybrid is composed of highly dispersed ZnO nanoparticles embedded on a lignin-based carbon nanosheet, showing excellent photogenerated electrons and holes separation and migration efficiency. The photocatalytic activity of LC/ZnO was much higher than the pure ZnO. The LC/ZnO hybrid composite showed different photocatalytic mechanism for degradation of negative methyl orange (MO) and positive Rhodamine B (RhB). It showed that h+ was the main photocatalytic active group during the degradation of MO, ·O2- and ·OH were the photocatalytic active groups during degradation of RhB. This reported photocatalyst with selective degradation of positive and negative organic dyes may have a great application prospect for photoelectric conversion and catalytic materials. Results of this work were of practical importance for high-valued utilization of lignin for carbon materials.

Recognizing facial expressions is an important social skill. In some psychological disorders such as schizophrenia, loss of this skill may complicate the patient's daily life. Prior research has shown that information technology may help to develop facial expression recognition skills through educational software and games. To examine if a computer game designed for teaching facial expressions would improve facial expression recognition skills of patients with schizophrenia. We developed a website composed of eight serious games. Thirty-two patients were given a pre-test composed of 21 facial expression photographs. Eighteen patients were in the study group while 14 were in the control group. Patients in the study group were asked to play the games on the website. After a period of one month, we performed a post-test for all patients. The median score of the correct answers was 17.5 in the control group whereas it was 16.5 in the study group (of 21) in pretest. The median post-test score was 18 in the control group (p=0.052) whereas it was 20 in the study group (p<0.001). Computer games may be used for the purpose of educating people who have difficulty in recognizing facial expressions.

2002-07-01

The utility of various measures of malingering was evaluated using an analog design in which half the participants (composed of three groups: naive healthy people, professionals working with head-injured people, individuals who suffered a head injury but not currently in litigation) were asked to try their best and the remainder was asked to feign believable injury. Participants were assessed with the Reliable Digit Span (RDS) task, the Victoria Symptom Validity Test (VSVT), and the Computerized Dot Counting Test (CDCT) on three separate occasions in order to determine whether repeat administration of tests improves prediction. The results indicated that regardless of an individual's experience, consideration of both level of performance (particularly on forced-choice symptom validity tasks) and intraindividual variability holds considerable promise for the detection of malingering.

A model construction for classification of women with normal, hypertensive and preeclamptic pregnancy in different gestational ages using maternal heart rate variability (HRV) indexes. In the present work, we applied the artificial neural network for the classification problem, using the signal composed by the time intervals between consecutive RR peaks (RR) (n = 568) obtained from ECG records. Beside the HRV indexes, we also considered other factors like maternal history and blood pressure measurements. The obtained result reveals sensitivity for preeclampsia around 80% that increases for hypertensive and normal pregnancy groups. On the other hand, specificity is around 85-90%. These results indicate that the combination of HRV indexes with artificial neural networks (ANN) could be helpful for pregnancy study and characterization.

Working Group Proposed to Preserve Archival Records

NASA Astrophysics Data System (ADS)

Bartlett, Jennifer L.

2013-01-01

The AAS and AIP co-hosted a Workshop in April 2012 with NSF support (AST-1110231) that recommends establishing a Working Group on Time Domain Astronomy (WGTDA) to encourage and advise on preserving historical observations in a form meaningful for future scientific analysis. Participants specifically considered archival observations that could describe how astronomical objects change over time. Modern techniques and increased storage capacity enable extracting additional information from older media. Despite the photographic plate focus, other formats also concerned participants. To prioritize preservation efforts, participants recommended considering the information density, the amount of previously published data, their format and associated materials, their current condition, and their expected deterioration rate. Because the best digitization still produces an observation of an observation, the originals should be retained. For accessibility, participants recommended that observations and their metadata be available digitally and on-line. Standardized systems for classifying, organizing, and listing holdings should enable discovery of historical observations through the Virtual Astronomical Observatory. Participants recommended pilot projects that produce scientific results, demonstrate the dependence of some advances on heritage data, and open new avenues of exploration. Surveying a broad region of the sky with a long time-base and high cadence should reveal new phenomena and improve statistics for rare events. Adequate financial support is essential. While their capacity to produce new science is the primary motivation for preserving astronomical records, their potential for historical research and citizen science allows targeting cultural institutions and other private sources. A committee was elected to prepare the WGTDA proposal. The WGTDA executive committee should be composed of ~10 members representing modern surveys, heritage materials, data management, data standardization and integration, follow-up of time-domain discoveries, and virtual observatories. The Working Group on the Preservation of Astronomical Heritage Web page includes a full report.

The pharmacologic management of rheumatoid arthritis has progressed substantially over the past years. It is therefore desirable that existing information be periodically updated. There are several published international guidelines for the treatment of rheumatoid arthritis that hardly adapt to the Mexican health system because of its limited healthcare resources. Hence, it is imperative to unify the existing recommendations and to incorporate them to a set of clinical, updated recommendations; the Mexican College of Rheumatology developed these recommendations in order to offer an integral management approach of rheumatoid arthritis according to the resources of the Mexican health system. To review, update and improve the available evidence within clinical practice guidelines on the pharmacological management of rheumatoid arthritis and produce a set of recommendations adapted to the Mexican health system, according to evidence available through December 2012. The working group was composed of 30 trained and experienced rheumatologists with a high quality of clinical knowledge and judgment. Recommendations were based on the highest quality evidence from the previously established treatment guidelines, meta-analysis and controlled clinical trials for the adult population with rheumatoid arthritis. During the conformation of this document, each working group settled the existing evidence from the different topics according to their experience. Finally, all the evidence and decisions were unified into a single document, treatment algorithm and drug standardization tables. This update of the Mexican Guidelines for the Pharmacologic Treatment of Rheumatoid Arthritis provides the highest quality information available at the time the working group undertook this review and contextualizes its use for the complex Mexican health system.

Classification of G-protein coupled receptors based on a rich generation of convolutional neural network, N-gram transformation and multiple sequence alignments.

PubMed

Li, Man; Ling, Cheng; Xu, Qi; Gao, Jingyang

2018-02-01

Sequence classification is crucial in predicting the function of newly discovered sequences. In recent years, the prediction of the incremental large-scale and diversity of sequences has heavily relied on the involvement of machine-learning algorithms. To improve prediction accuracy, these algorithms must confront the key challenge of extracting valuable features. In this work, we propose a feature-enhanced protein classification approach, considering the rich generation of multiple sequence alignment algorithms, N-gram probabilistic language model and the deep learning technique. The essence behind the proposed method is that if each group of sequences can be represented by one feature sequence, composed of homologous sites, there should be less loss when the sequence is rebuilt, when a more relevant sequence is added to the group. On the basis of this consideration, the prediction becomes whether a query sequence belonging to a group of sequences can be transferred to calculate the probability that the new feature sequence evolves from the original one. The proposed work focuses on the hierarchical classification of G-protein Coupled Receptors (GPCRs), which begins by extracting the feature sequences from the multiple sequence alignment results of the GPCRs sub-subfamilies. The N-gram model is then applied to construct the input vectors. Finally, these vectors are imported into a convolutional neural network to make a prediction. The experimental results elucidate that the proposed method provides significant performance improvements. The classification error rate of the proposed method is reduced by at least 4.67% (family level I) and 5.75% (family Level II), in comparison with the current state-of-the-art methods. The implementation program of the proposed work is freely available at: https://github.com/alanFchina/CNN .

Purpose Recent advances in imaging, use of prognostic indices, and molecular profiling techniques have the potential to improve disease characterization and outcomes in lymphoma. International trials are under way to test image-based response–adapted treatment guided by early interim positron emission tomography (PET) –computed tomography (CT). Progress in imaging is influencing trial design and affecting clinical practice. In particular, a five-point scale to grade response using PET-CT, which can be adapted to suit requirements for early- and late-response assessment with good interobserver agreement, is becoming widely used both in practice- and response-adapted trials. A workshop held at the 11th International Conference on Malignant Lymphomas (ICML) in 2011 concluded that revision to current staging and response criteria was timely. Methods An imaging working group composed of representatives from major international cooperative groups was asked to review the literature, share knowledge about research in progress, and identify key areas for research pertaining to imaging and lymphoma. Results A working paper was circulated for comment and presented at the Fourth International Workshop on PET in Lymphoma in Menton, France, and the 12th ICML in Lugano, Switzerland, to update the International Harmonisation Project guidance regarding PET. Recommendations were made to optimize the use of PET-CT in staging and response assessment of lymphoma, including qualitative and quantitative methods.

Gougar, Hans David

2015-10-01

The United States Department of Energy (DOE) commissioned a study the suitability of different advanced reactor concepts to support materials irradiations (i.e. a test reactor) or to demonstrate an advanced power plant/fuel cycle concept (demonstration reactor). As part of the study, an assessment of the technical maturity of the individual concepts was undertaken to see which, if any, can support near-term deployment. A Working Group composed of the authors of this document performed the maturity assessment using the Technical Readiness Levels as defined in DOE’s Technology Readiness Guide . One representative design was selected for assessment from of each ofmore » the six Generation-IV reactor types: gas-cooled fast reactor (GFR), lead-cooled fast reactor (LFR), molten salt reactor (MSR), supercritical water-cooled reactor (SCWR), sodium-cooled fast reactor (SFR), and very high temperature reactor (VHTR). Background information was obtained from previous detailed evaluations such as the Generation-IV Roadmap but other technical references were also used including consultations with concept proponents and subject matter experts. Outside of Generation IV activity in which the US is a party, non-U.S. experience or data sources were generally not factored into the evaluations as one cannot assume that this data is easily available or of sufficient quality to be used for licensing a US facility. The Working Group established the scope of the assessment (which systems and subsystems needed to be considered), adapted a specific technology readiness scale, and scored each system through discussions designed to achieve internal consistency across concepts. In general, the Working Group sought to determine which of the reactor options have sufficient maturity to serve either the test or demonstration reactor missions.« less

Mid-term results of ankle fractures with and without syndesmotic rupture.

2015-03-01

This study investigated the effect of short term removal of syndesmotic screws on the ankle function after 6 years, as there still exists controversy on the duration of screw stabilization. Patients with an ankle fracture who received surgery between 1998 and 2004 were reviewed. One group was composed of patients with an ankle fracture needing a syndesmotic repair with screws. The second was composed of operated patients that did not need syndesmotic repair. The primary scoring used was the Olerud-Molander Ankle Score (OMAS). A total of 59 patients were studied with comparable characteristics, with no significant difference on the OMAS after 6 years between the repair group (81.9) and the non-repair group (90.4). On additional clinical scoring groups remained the same. Joint degeneration was seen in both groups (86.7% vs. 55.5%). Patients with ankle fractures using syndesmotic repair and screw removal after 8 weeks and operated patients without syndesmotic injury have comparable results after 6 years.

2014-05-15

Whole genome sequencing of six diagnostic brucellaphages, Tbilisi (Tb), Firenze (Fz), Weybridge (Wb), S708, Berkeley (Bk) and R/C, was followed with genomic comparisons including recently described genomes of the Tb phage from Mexico (TbM) and Pr phage to elucidate genomic diversity and candidate host range determinants. Comparative whole genome analysis revealed high sequence homogeneity among these brucellaphage genomes and resolved three genetic groups consistent with defined host range phenotypes. Group I was composed of Tb and Fz phages that are predominantly lytic for Brucella abortus and Brucella neotomae; Group II included Bk, R/C, and Pr phages that are lytic mainly for B. abortus, Brucella melitensis and Brucella suis; Group III was composed of Wb and S708 phages that are lytic for B. suis, B. abortus and B. neotomae. We found that the putative phage collar protein is a variable locus with features that may be contributing to the host specificities exhibited by different brucellaphage groups. The presence of several candidate host range determinants is illustrated herein for future dissection of the differential host specificity observed among these phages. Published by Elsevier B.V.

Activity of [des-Aspartyl1]-Angiotensin II in Primary Aldosteronism

1979-01-01

This study describes the effects of [des-Aspartyl1]-angiotensin II ([des-Asp]-AII) on blood pressure and aldosterone production in patients with primary aldosteronism due to aldosterone-producing adrenal adenoma (APA) and idiopathic adrenal hyperplasia (IHA), and in normotensive control subjects. 10 patients with primary aldosteronism, 7 with APA and 3 with IHA, and 6 normotensive control subjects were placed on a constant 150-meq sodium diet for 4 days. [des-Asp]-AII was infused for 30 min at 6, 12, and 18 pmol/kg per min. Three groups of patients were identified on the basis of aldosterone response to [des-Asp]-AII. Group I, composed of normotensive control subjects, showed incremental increases in plasma aldosterone concentration from 6±1 to 14±3 ng/100 ml (P < 0.01) with [des-Asp]-AII infusion. Group II, composed of patients with primary aldosteronism, showed incremental increases in plasma aldosterone concentration from 33±8 to 65±13 ng/100 ml (P < 0.05) with 12 pmol/kg per min of [des-Asp]-AII. Group III, also composed of patients with primary aldosteronism, showed no increase of plasma aldosterone concentration with [des-Asp]-AII. Groups I and II showed similar percentage increases in plasma aldosterone concentration (P = NS). Group III showed significantly lower aldosterone responses than group I (P < 0.01). Group II included all patients with IHA and two patients with APA. Group III included only patients with APA. The blood pressure responses to [des-Asp]-AII of subjects in group I did not differ significantly from those of groups II or III. Thus, patients with IHA and a subgroup of patients with APA showed responsiveness to [des-Asp]-AII which was limited to adrenal cortical stimulation of aldosterone biosynthesis. This suggests that adrenal responsiveness to angiotensin is a major control mechanism in some forms of primary aldosteronism. The differential adrenal responsiveness to [des-Asp]-AII in patients with APA indicates either that there are two distinct subpopulations of APA, or that alteration in tumor response to angiotensin occurs during the natural progression of the disease history.

Diffusion Restrictions Surrounding Mitochondria: A Mathematical Model of Heart Muscle Fibers

PubMed Central

Ramay, Hena R.; Vendelin, Marko

2009-01-01

Abstract Several experiments on permeabilized heart muscle fibers suggest the existence of diffusion restrictions grouping mitochondria and surrounding ATPases. The specific causes of these restrictions are not known, but intracellular structures are speculated to act as diffusion barriers. In this work, we assume that diffusion restrictions are induced by sarcoplasmic reticulum (SR), cytoskeleton proteins localized near SR, and crowding of cytosolic proteins. The aim of this work was to test whether such localization of diffusion restrictions would be consistent with the available experimental data and evaluate the extent of the restrictions. For that, a three-dimensional finite-element model was composed with the geometry based on mitochondrial and SR structural organization. Diffusion restrictions induced by SR and cytoskeleton proteins were varied with other model parameters to fit the set of experimental data obtained on permeabilized rat heart muscle fibers. There are many sets of model parameters that were able to reproduce all experiments considered in this work. However, in all the sets, <5–6% of the surface formed by SR and associated cytoskeleton proteins is permeable to metabolites. Such a low level of permeability indicates that the proteins should play a dominant part in formation of the diffusion restrictions. PMID:19619458

The aim of the present study was to analyze the lipid profile of follicular fluid from patients with endometriosis and endometrioma who underwent in vitro fertilization treatment (IVF). The control group (n = 10) was composed of women with tubal factor or minimal male factor infertility who had positive pregnancy outcomes after IVF. The endometriosis group consisted of women with endometriosis diagnosed by videolaparoscopy (n = 10), and from the same patients, the endometriomas fluids were collected, which composed the endometrioma group (n = 10). From the follicular fluid and endometriomas, lipids were extracted by the Bligh and Dyer method, and the samples were analyzed by tandem mass spectrometry. We observed phosphatidylglycerol phosphate, phosphatidylcholine, phosphatidylserine, and phosphatidylnositol bisphosphate in the control group. In the endometriosis group, sphingolipids and phosphatidylcholines were more abundant, while in the endometrioma group, sphingolipids and phosphatidylcholines with different m/z from the endometriosis group were found in high abundance. This analysis demonstrated that there is a differential representation of these lipids according to their respective groups. In addition, the lipids found are involved in important mechanisms related to endometriosis progress in the ovary. Thus, the metabolomic approach for the study of lipids may be helpful in potential biomarker discovery.

We describe the development and evaluation of a secure Web-based system for the purpose of collaborative care called Loop. Loop assembles the team of care with the patient as an integral member of the team in a secure space. The objectives of this paper are to present the iterative design of the separate views for health care providers (HCPs) within each patient's secure space and examine patients', caregivers', and HCPs' perspectives on this separate view for HCP-only communication. The overall research program includes cycles of ethnography, prototyping, usability testing, and pilot testing. This paper describes the usability testing phase that directly informed development. A descriptive qualitative approach was used to analyze participant perspectives that emerged during usability testing. During usability testing, we sampled 89 participants from three user groups: 23 patients, 19 caregivers, and 47 HCPs. Almost all perspectives from the three user groups supported the need for an HCP-only communication view. In an earlier prototype, the visual presentation caused confusion among HCPs when reading and composing messages about whether a message was visible to the patient. Usability testing guided us to design a more deliberate distinction between posting in the Patient and Team view and the Health Care Provider Only view at the time of composing a message, which once posted is distinguished by an icon. The team made a decision to incorporate an HCP-only communication view based on findings during earlier phases of work. During usability testing we tested the separate communication views, and all groups supported this partition. We spent considerable effort designing the partition; however, preliminary findings from the next phase of evaluation, pilot testing, show that the Patient and Team communication is predominantly being used. This demonstrates the importance of a subsequent phase of the clinical trial of Loop to validate the concept and design.

The aim of this study was to test the association between hematological/genetic factors and cerebral vasculopathy in children with sickle cell anemia (SCA). A group with cerebral vasculopathy (VASC) was composed of children who had stroke (n = 6), silent infarct (n = 11), or an abnormal transcranial Doppler (n = 5). Eighty-four patients had neither positive history of stroke or silent infarct, nor abnormal transcranial Doppler (NORM group). An intermediate group (COND; n = 15) was composed of SCA children with a conditional transcranial Doppler. Biological analyses were performed on samples obtained at steady state and before the beginning of any chronic treatment. The comparisons of the three groups demonstrated a protective effect of α-thalassemia against cerebral vasculopathy through its effects on hemoglobin and reticulocyte levels. Moreover, we observed higher frequency of G6PD deficiency in the VASC group compared with the other groups. Our study confirms the key role of α-thalassemia and G6PD status in the pathophysiology of cerebral vasculopathy in SCA children. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Berthelon, Catherine; Damm, Loïc

2012-01-01

In order to prevent the over-representation of young drivers in car crashes, France instated an early driver training from the age of 16, but the positive effects of this opportunity have not yet been proven. Three groups of male drivers (12 subjects each) were confronted with some prototypical accident scenarios introduced in a simulated urban circuit. The first and second groups were composed of young drivers having less than one month of driving licence; twelve have had a traditional learning course, and twelve had followed, in addition to the initial course, an early driver training under the supervision of an adult. The third group was composed of experienced drivers. Strategies of the three groups were analyzed through their response time, speed and maneuvers. No difference appeared across groups regarding obstacle detection. But traditionally-trained drivers' position control was more conservative than the two others groups, which were more likely to involve efficient evasive action. The exposure gained during early training could thus increase the development of visuo-motor coordination and involve better skills in case of difficult situations. Others accidents' scenarios could be used to confront young drivers with difficult situations not commonly encountered in natural driving.

Fractures of the distal tibia, ankle, and foot sustained through a high-energy mechanism can be extremely debilitating, and ankle and/or subtalar fusion may be indicated if the limb is deemed salvageable. Functional outcomes among this population are often poor. The purposes of this study were to evaluate the effect of an advanced rehabilitation program combined with the use of a custom ankle-foot orthosis for patients with ankle or subtalar fusion on selected physical performance measures and patient-derived outcome measures and to determine if the response to treatment was predicated upon the type of fusion. We conducted a prospective, longitudinal, observational, cohort study composed of 23 active duty Service Members treated for lower extremity trauma. Patients were separated into 2 groups: group 1 was composed of 12 patients who underwent isolated ankle fusion or ankle fusion combined with ipsilateral subtalar fusion, group 2 was composed of 11 patients who underwent subtalar fusion only. Patient-reported outcome (PRO) measures and physical performance measures were recorded at baseline and at the conclusion of the rehabilitation program. Significant improvements in both groups were seen in each of the 4 physical performance measures. Only group 2 showed significant improvements in all domains of the Veteran's Rand 12-Item Health Survey (VR-12) and Short Musculoskeletal Function Assessment (SMFA) at all points during the course of rehabilitation. Among a subset of patients treated for severe lower extremity trauma with ankle and/or subtalar fusion, an integrated orthotic and rehabilitation initiative improved physical performance and PRO measures over an 8-week course.

Pairwise gene GO-based measures for biclustering of high-dimensional expression data.

PubMed

2018-01-01

Biclustering algorithms search for groups of genes that share the same behavior under a subset of samples in gene expression data. Nowadays, the biological knowledge available in public repositories can be used to drive these algorithms to find biclusters composed of groups of genes functionally coherent. On the other hand, a distance among genes can be defined according to their information stored in Gene Ontology (GO). Gene pairwise GO semantic similarity measures report a value for each pair of genes which establishes their functional similarity. A scatter search-based algorithm that optimizes a merit function that integrates GO information is studied in this paper. This merit function uses a term that addresses the information through a GO measure. The effect of two possible different gene pairwise GO measures on the performance of the algorithm is analyzed. Firstly, three well known yeast datasets with approximately one thousand of genes are studied. Secondly, a group of human datasets related to clinical data of cancer is also explored by the algorithm. Most of these data are high-dimensional datasets composed of a huge number of genes. The resultant biclusters reveal groups of genes linked by a same functionality when the search procedure is driven by one of the proposed GO measures. Furthermore, a qualitative biological study of a group of biclusters show their relevance from a cancer disease perspective. It can be concluded that the integration of biological information improves the performance of the biclustering process. The two different GO measures studied show an improvement in the results obtained for the yeast dataset. However, if datasets are composed of a huge number of genes, only one of them really improves the algorithm performance. This second case constitutes a clear option to explore interesting datasets from a clinical point of view.

From Trioleoyl glycerol to extra virgin olive oil through multicomponent triacylglycerol mixtures: Crystallization and polymorphic transformation examined with differential scanning calorimetry and X-ray diffration techniques.

The polymorphic crystallization and transformation behavior of extra virgin olive oil (EVOO) was examined by using differential scanning calorimetry (DSC) and X-ray diffraction with both laboratory-scale (XRD) and synchrotron radiation source (SR-XRD). The complex behavior observed was studied by previously analyzing mixtures composed by its main 2 to 6 triacylglycerol (TAG) components. Thus, component TAGs were successively added to simulate EVOO composition, until reaching a 6 TAGs mixture, composed by trioleoyl glycerol (OOO), 1-palmitoyl-2,3-dioleoyl glycerol (POO), 1,2-dioleoyl-3-linoleoyl glycerol (OOL), 1-palmitoyl-2-oleoyl-3-linoleoyl glycerol (POL), 1,2-dipalmitoyl-3-oleoyl glycerol (PPO) and 1-stearoyl-2,3-dioleoyl glycerol (SOO). Molten samples were cooled from 25°C to -80°C at a controlled rate of 2°C/min and subsequently heated at the same rate. The polymorphic behavior observed in multicomponent TAG mixtures was interpreted by considering three main groups of TAGs with different molecular structures: triunsaturated OOO and OOL, saturated-unsaturated-unsaturated POO, POL and SOO, and saturated-saturated-unsaturated PPO. As confirmed by our previous work, TAGs belonging to the same structural group displayed a highly similar polymorphic behavior. EVOO exhibited two different β'-2L polymorphic forms (β' 2 -2L and β' 1 -2L), which transformed into β'-3L when heated. Equivalent polymorphic pathways were detected when the same experimental conditions were applied to the 6 TAG components mixture. Hence, minor components may not exert a strong influence in this case. Copyright © 2017 Elsevier Ltd. All rights reserved.

Comparison of genetic diversity between Canadian adapted genotypes and exotic germplasm of soybean.

PubMed

Iquira, Elmer; Gagnon, Eric; Belzile, François

2010-05-01

Soybean (Glycine max (L.) Merr.) was domesticated in China and the greatest genetic diversity for this species is found in Asia. In contrast, in North America, soybean cultivars trace back to a small number of plant introductions from Asia and genetic diversity is typically quite limited. The purpose of this work was to measure and compare the genetic diversity in two sets of soybean lines. The first set (termed "local") was composed of 100 lines used in a private breeding program in Quebec. The second set (termed "exotic") was composed of 200 lines from elsewhere in the world (but mostly from Asia) and included a few lines of Glycine soja, the wild progenitor of cultivated soybean. Almost all the genotypes belonged to maturity groups between 000 and II. A total of 39 microsatellites (SSRs) were used to genotype the two collections. The number of alleles per locus was almost twice as great in the exotic set compared with the local set. Also, the number of "unique" alleles, i.e., those uniquely present in one set and absent in the other, was almost fivefold greater (191 vs. 37) in a subset of 108 exotic lines with good adaptation than among the local set. A genetic distance matrix, a UPGMA cluster analysis, and a principal coordinate analysis were conducted based on the SSR data. These analyses all indicated that the exotic set was much more diverse and formed a clearly distinct group from the local set. Interestingly, some of the lines showing the best adaptation to local conditions were quite distinctive in terms of their genotype and could potentially contribute useful novel genetic variation within the breeding program.

Measuring Sojourner Adjustment among American students studying abroad

The literature on “Sojourner Adjustment,” a term expanding on the acculturation concept to apply to groups residing temporarily in foreign environments, suggests that engagement, participation, and temporary integration into the host culture may contribute to less psychological and sociocultural difficulty while abroad. The present study was designed to establish a brief multi-component measure of Sojourner Adjustment (the Sojourner Adjustment Measure; SAM) to be used in work with populations residing temporarily in foreign environments (e.g., international students, foreign aid workers). Using exploratory and confirmatory factor analyses on a sample of 248 American study abroad college students, we established a 24-item measure of Sojourner Adjustment composed of four positive factors (social interaction with host nationals, cultural understanding and participation, language development and use, host culture identification) and two negative factors (social interaction with co-nationals, homesickness/feeling out of place). Preliminary convergent validity was examined through correlations with established measures of acculturation. Further research with the SAM is encouraged to explore the relevance of this measure with other groups of sojourners (e.g., foreign aid workers, international businessmen, military personnel) and to determine how SAM factors relate to psychological well-being, health behaviors, and risk behaviors abroad among these diverse groups.

The politics of Latin American family-planning policy.

PubMed

Weaver, J L

1978-07-01

In population planning in Latin America the programs are as successful as the government's support of family planning. Colombia is one of the few Latin American countries which has actively exhorted its populace to birth control. If the propensity for large families reflects a belief in the economic or social utility of children, instead of machismo, birthrates will fall with expanded social security and economic welfare programs. If birthrates are the result of machismo, new gender models stressing the positive rewards and social esteem to be gained through responsible parenthood would have to be taught to both adults and children. The position profamily planning in most Latin American countries is generally supported by the ministers, technocrats, corporations, businessmen, middle-class women, doctors, mass media, protestant congregations, and working-class women. Family planning is usually opposed by members of the armed forces, Catholic hierarchy, Catholic lay organizations, oligarchy, university students, leftist intellectuals, Marxist insurgents, Indian communities, and peasants. The portion of the total national populations encompassed by the groups composing the core combination, ideological bias, and stability group ranges from 50-60% in Argentina, Uruguay, and Venezuela to 10-20% in Central America, Bolivia, Ecuador, and Paraguay. Most groups are outside the policy-making process.

Identifying ecological "sweet spots" underlying cyanobacteria functional group dynamics from long-term observations using a statistical machine learning approach

Diversity in the eco-physiological adaptations of cyanobacteria genera creates challenges for water managers who are tasked with developing appropriate actions for controlling not only the intensity and frequency of cyanobacteria blooms, but also reducing the potential for blooms of harmful taxa (e.g., toxin producers, N2 fixers). Compounding these challenges, the efficacy of nutrient management strategies (phosphorus-only versus nitrogen-and-phosphorus) for cyanobacteria bloom abatement is the subject of an ongoing debate, which increases uncertainty associated with bloom mitigation decision-making. In this work, we analyze a unique long-term (17-year) dataset composed of monthly observations of cyanobacteria genera abundances, zooplankton abundances, water quality, and flow from Lake George, a bloom-impacted flow-through lake of the St. Johns River (FL, USA). Using the Random Forests machine learning algorithm, an assumption-free ensemble modeling approach, the dataset was evaluated to quantify and characterize relationships between environmental conditions and seven cyanobacteria groupings: five genera (Anabaena, Cylindrospermopsis, Lyngbya, Microcystis, and Oscillatoria) and two functional groups (N2 fixers and non-fixers). Results highlight the selectivity of nitrogen in describing genera and functional group dynamics, and potential for physical effects to limit the efficacy of nutrient management as a mechanism for cyanobacteria bloom mitigation.

Modeling and Composing Scenario-Based Requirements with Aspects

There has been significant recent interest, within the Aspect-Oriented Software Development (AOSD) community, in representing crosscutting concerns at various stages of the software lifecycle. However, most of these efforts have concentrated on the design and implementation phases. We focus in this paper on representing aspects during use case modeling. In particular, we focus on scenario-based requirements and show how to compose aspectual and non-aspectual scenarios so that they can be simulated as a whole. Non-aspectual scenarios are modeled as UML sequence diagram. Aspectual scenarios are modeled as Interaction Pattern Specifications (IPS). In order to simulate them, the scenarios are transformed into a set of executable state machines using an existing state machine synthesis algorithm. Previous work composed aspectual and non-aspectual scenarios at the sequence diagram level. In this paper, the composition is done at the state machine level.

An electrolytic method is given for obtaining pure thorium, uranium, and thorium-uranium alloys. The electrolytic cell comprises a cathode composed of a metal selected from the class consisting of zinc, cadmium, tin, lead, antimony, and bismuth, an anode composed of at least one of the metals selected from the group consisting of thorium and uranium in an impure state, and an electrolyte composed of a fused salt containing at least one of the salts of the metals selected from the class consisting of thorium, uranium. zinc, cadmium, tin, lead, antimony, and bismuth. Electrolysis of the fused salt while the cathode is maintained in the molten condition deposits thorium, uranium, or thorium-uranium alloys in pure form in the molten cathode which thereafter may be separated from the molten cathode product by distillation.

Because classical music has greatly affected our life and culture in its long history, it has attracted extensive attention from researchers to understand laws behind it. Based on statistical physics, here we use a different method to investigate classical music, namely, by analyzing cumulative distribution functions (CDFs) and autocorrelation functions of pitch fluctuations in compositions. We analyze 1,876 compositions of five representative classical music composers across 164 years from Bach, to Mozart, to Beethoven, to Mendelsohn, and to Chopin. We report that the biggest pitch fluctuations of a composer gradually increase as time evolves from Bach time to Mendelsohn/Chopin time. In particular, for the compositions of a composer, the positive and negative tails of a CDF of pitch fluctuations are distributed not only in power laws (with the scale-free property), but also in symmetry (namely, the probability of a treble following a bass and that of a bass following a treble are basically the same for each composer). The power-law exponent decreases as time elapses. Further, we also calculate the autocorrelation function of the pitch fluctuation. The autocorrelation function shows a power-law distribution for each composer. Especially, the power-law exponents vary with the composers, indicating their different levels of long-range correlation of notes. This work not only suggests a way to understand and develop music from a viewpoint of statistical physics, but also enriches the realm of traditional statistical physics by analyzing music.

With the goal of improving yield and success rates of heterologous protein production for structural studies we have developed the database and algorithm software package Gene Composer. This freely available electronic tool facilitates the information-rich design of protein constructs and their engineered synthetic gene sequences, as detailed in the accompanying manuscript. In this report, we compare heterologous protein expression levels from native sequences to that of codon engineered synthetic gene constructs designed by Gene Composer. A test set of proteins including a human kinase (P38{alpha}), viral polymerase (HCV NS5B), and bacterial structural protein (FtsZ) were expressed in both E. colimore » and a cell-free wheat germ translation system. We also compare the protein expression levels in E. coli for a set of 11 different proteins with greatly varied G:C content and codon bias. The results consistently demonstrate that protein yields from codon engineered Gene Composer designs are as good as or better than those achieved from the synonymous native genes. Moreover, structure guided N- and C-terminal deletion constructs designed with the aid of Gene Composer can lead to greater success in gene to structure work as exemplified by the X-ray crystallographic structure determination of FtsZ from Bacillus subtilis. These results validate the Gene Composer algorithms, and suggest that using a combination of synthetic gene and protein construct engineering tools can improve the economics of gene to structure research.« less

Little is known about the scope of practice and outcomes in pediatric surgery performed by humanitarian organizations in resource-poor settings and conflict zones. This study provides the largest report to date detailing such data for a major nongovernmental organization providing humanitarian surgical relief support in these settings. To characterize pediatric surgical care provision by a major nongovernmental organization in specialized humanitarian settings and conflict zones. A retrospective cohort study was conducted from August 15, 2014, to March 9, 2015, of 59,928 surgical interventions carried out from January 1, 2012, to December 31, 2013, by the Médecins Sans Frontières Operational Centre Paris (MSF-OCP) program in 20 locations, including South Sudan, Yemen, Syria, Gaza, Pakistan, Nigeria, Central African Republic, Democratic Republic of Congo, and the Philippines. Surgical interventions were primarily for general surgical, traumatic, and obstetric emergencies and were categorized by mechanism, type of intervention, American Society of Anesthesia risk classification, and urgency of intervention. Operative indications, type of intervention, and operative case mortality. Among all age groups, 59,928 surgical interventions were performed in dedicated trauma, obstetric, and reconstructive centers for 2 years. Nearly one-third of interventions (18,040 [30.1%]) involved preteen patients (aged <13 years) and 4571 (7.6%) involved teenaged patients (aged 13-17 years). The proportion of violence-related injuries in the preteen group was significantly lower than in the teenage group (4.8% vs 17.5%; P < .001). Burns (50.1%), other accidental injuries (16.4%), and infections (23.4%) composed the bulk of indications in the preteen group. Interventions in the teenage group were principally caused by trauma-related injuries (burns, 22.9%; traffic accidents, 10.1%; gunshot wounds, 8.0%). Crude perioperative case mortality rates were 0.07% in the preteen group, 0.15% in the teenage group, and 0.22% in the adult group (>17 years) (P = .001). One-third of the cases (33.4%) were deemed urgent, while most of the remaining cases (57.7%) were deemed semielective (surgical intervention to be performed within 48 hours). When examining surgical interventions in a population of pediatric patients cared for in the specialized setting of humanitarian aid and conflict zones, burns, other accidental injuries, and infection composed the bulk of indications in the preteen group; interventions in the teenage group were principally caused by trauma-related injuries. Crude perioperative case mortality rates in the preteen group were significantly lower than in the adult group. Further work is needed to examine long-term outcomes of pediatric operations in these settings and to guide context-specific surgical program development.

The International Classification of Functioning, Disability and Health (ICF) should be used as the framework for the development of a clinical assessment schedule for clinical quality management of health-related rehabilitation services. For the description of rehabilitation services a working group of the ISPRM-WHO-Liaison Committee proposed an instrument called "International Classification System for Service Organization in Health-related Rehabilitation" or ICSO-R. To test the applicability and feasibility of ICSO-R to describe rehabilitation services and to propose further improvements. A workshop was held. SPF (Swiss Paraplegic Research) in Nottwil, January 2016. Six working groups, composed of delegates from UEMS PRM (Physical and Rehabilitation Medicine Section and Board of the European Union of Medical Specialists) and experts from other rehabilitation professions. Each working group selected an existing service of a predefined category (one acute, three post-acute and two long-term rehabilitation services). The instructions were: 1) make a narrative description of an exemplary service; 2) describe the exemplary service using the dimensions and categories of ICSO-R; 3) comment on feasibility of the ICSO-R table, on shortcomings, and make suggestions for improvement. The narrative and ICSO-R descriptions were analyzed and compared, and recommendations were made for modification of ICSO-R. The narratives were very heterogeneous and none comparable. ICSO-R use was feasible and significantly increased precision and comparability of the descriptions of existing rehabilitation services. Proposals for improvement were made, for example the addition of lacking categories. Suggestions were made for clarification of a number of characteristics, including a taxonomy with value sets. The UEMS PRM workshop on the description of health-related rehabilitation services for use in a clinical quality management schedule clearly demonstrated feasibility and applicability of ICSO-R, showing more precise and comparable descriptions as compared to the narratives. However, in a next version some modifications should be made to improve clarity. It is recommended to use ICSO-R to describe and compare existing as well as model rehabilitation services for benchmarking and implementation into health systems worldwide. The ISPRM-WHO Liaison committee working group will further modify and improve ICSO-R.

It is essential to know the thyroid gland morphology and its anatomical relations in the anterior compartment of the neck in order to minimize the rate of thyroid surgery morbidity, especially the lesion of parathyroid glands and laryngeal nerves. The aim of this study was the identification of parathyroid glands in cadaver parts and their histological confirmation. Twenty cadaver parts were used to simulate thyroidectomies. During dissection, the thyroid glands and eventual parathyroid glands were isolated and then submitted to histological study. Twenty cadaver parts (anterior cervical organs) were used for macroscopic dissection during which 48 fragments that corresponded to eventual parathyroid glands were isolated, 35 of which were effectively confirmed through histological observation to be parathyroid glands. The 20 cadaver parts were then divided into three groups according to the number of histologically confirmed parathyroid glands. In the first group, composed of 11 cases, all eventual parathyroid glands were confirmed. In the second group, composed of six cases, only some glands were confirmed. In the third group, composed of three cases, none of the possible glands were confirmed. In seven of the 20 isolated thyroid glands, eight parathyroid glands were identified during histological study: four subcapsular, three extra-capsular, one intra-thyroidal. There was no statistical relation in the dimensions of the parathyroid glands. The knowledge of the anatomy of the central visceral compartment of the neck and its most frequent variations reduces but doesn't eliminate thyroid surgery morbidity, especially parathyroid iatrogenic excision, difficulty which has been demonstrated during the dissection of cadaver parts.

In general, bio-macromolecules are composed of hydrophilic and hydrophobic moieties and are confined within small cavities, such as cell membranes and intracellular organelles. Here, we studied the self-organization of macromolecules having groups with different affinities to solvents under spherical nano-scale confinement by means of computer modeling. It is shown that depending on the interaction parameters of monomer units composed of side- and main-chain monomer groups along a single linear macromolecule and on cavity size, such amphiphilic polymers undergo the conformational transitions between hollow nanospheres, rod-like and folded cylindrical structures, and a necklace conformation with and without a particular ordering of beads. The diagram of the conformations in the variables the incompatibility parameter of monomer units and the cavity radius is constructed.

[Purpose] The aim of this study was to investigate the clinical effects of a nutraceutical composed (Xinepa®) combined with extremely-low-frequency electromagnetic fields in the carpal tunnel syndrome. [Subjects and Methods] Thirty-one patients with carpal tunnel syndrome were randomized into group 1-A (N=16) (nutraceutical + extremely-low-frequency electromagnetic fields) and group 2-C (n=15) (placebo + extremely-low-frequency electromagnetic fields). The dietary supplement with nutraceutical was twice daily for one month in the 1-A group and both groups received extremely-low-frequency electromagnetic fields at the level of the carpal tunnel 3 times per week for 12 sessions. The Visual Analogue Scale for pain, the Symptoms Severity Scale and Functional Severity Scale of the Boston Carpal Tunnel Questionnaire were used at pre-treatment (T0), after the end of treatment (T1) and at 3 months post-treatment (T2). [Results] At T1 and T2 were not significant differences in outcome measures between the two groups. In group 1-A a significant improvement in the scales were observed at T1 and T2. In group 2-C it was observed only at T1. [Conclusion] Significant clinical effects from pre-treatment to the end of treatment were shown in both groups. Only in group 1-A they were maintained at 3 months post-treatment.

The current study evaluated whether or not there were significant differences in psychopathological traits between three groups of individuals. The first was a group of patients seeking bariatric surgery diagnosed as being affected by Binge Eating Disorder (BED), according to the new criteria of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders. This group (NEW BED group) did not meet BED diagnosis following the previous criteria listed in the DSM-IV-TR. The second group of individuals was composed of severely obese patients seeking bariatric surgery not affected by an eating disorder, according to the diagnostic criteria of the DSM-5 (OB group). The third group was composed of individuals within a healthy weight range (Control group). 94 severely obese patients (33 in the NEW BED group and 61 in the OB group) were compared to the Control group including 41 participants on depression, anxiety and eating habits. The NEW BED scored significantly higher than the OB group on the Beck Depression Inventory, both the subscales of the State Trait Anxiety Inventory, on disinhibition and hunger subscales of the Three-Factor Eating Questionnaire and on many subscales of the Eating Disorders Inventory. The new, less restrictive diagnostic criteria for BED of the DSM-5 are useful in identifying obese patients affected by severe psychopathology and dysfunctional eating habits.

The present study was undertaken to estimate the effect of occupational exposure to lead on the blood concentration of glucose and several enzymes involved in glycolysis, the citric acid cycle, and the pentose phosphate pathway. To estimate the degree of lipid peroxidation, the concentrations of conjugated dienes were determined. The examined group included 145 healthy male employees of lead-zinc works. Taking into account the mean blood lead levels, the examined group was divided into two subgroups. The control group was composed of 36 healthy male administrative workers. The markers of lead exposure were significantly elevated in both subgroups when compared with the controls. There were no significant changes in fasting glucose concentration and fructose-1,6-bisphosphate aldolase activity in the study population. The concentration of conjugated dienes was significantly higher in both subgroups, whereas the activity of malate dehydrogenase was significantly higher only in the group with higher exposure. The activities of lactate dehydrogenase and sorbitol dehydrogenase were significantly decreased in the examined subgroups. The activity of glucose-6-phosphate dehydrogenase decreased significantly in the group with higher exposure and could be the cause of the elevated concentrations of conjugated dienes. It is possible to conclude that lead interferes with carbohydrate metabolism, but compensatory mechanisms seem to be efficient, as glucose homeostasis in lead-exposed workers was not disturbed. © The Author(s) 2013.

Evolving a NASA Digital Object Identifiers System with Community Engagement

NASA Astrophysics Data System (ADS)

Wanchoo, L.; James, N.

2016-12-01

In 2010, NASA's Earth Science Data and Information System (ESDIS) Project began investigating the assignment of unique identifiers to its suite of data products being stewarded at data centers distributed across the country. This process led to the use of Digital Object Identifiers (DOIs) and the development of an automated system for the registration of these DOIs. Since that time, the ESDIS DOI registration system has evolved to be fully functional with over 3000 publicly accessible DOIs and over 1000 being held in reserve status until the information required for registration is obtained. The goal is to assign DOIs to the entire 7000+ data collections under ESDIS management via its network of discipline-oriented data centers. A key factor in the successful evolution of the DOI registration system has been the incorporation of community input. Over the last 3 years, ESDIS has solicited community input for making the DOI registration process more efficient through three focus groups under NASA's Earth Science Data System Working Group (ESDSWG). These groups were largely composed of DOI submitters and data curators from the 12 data centers serving user communities of various science disciplines. The suggestions from these groups were formulated into recommendations for ESDIS consideration and implementation. This poster will describe the process and the activities of each focus group, their recommendations, and how these recommendations were implemented.

Occupational noise-induced tinnitus: does it affect workers' quality of life?

Muluk, Nuray Bayar; Oguztürk, Omer

2008-02-01

This prospective study aimed to investigate the quality of life of workers in a steel factory. The study group was composed of 16 male workers with tinnitus and 30 ears. Fifteen male workers without tinnitus and 30 ears were included into the control group. Workers were evaluated by questionnaire, pure-tone audiometry, and the SF-36 Health Survey. In the study group, tinnitus loudness levels (TLLs) were found. In the study group, the domains general mental health and role limitations owing to emotional problems were significantly lower than in the control group. Older age, industrial noise exposure over a long period, higher noise exposure during work, and hearing loss secondary to occupational noise caused workers to experience higher TLLs. Earheadings protected workers more than earplugs, and TLLs were lower. Important factors that affect workers' quality of life are maximum exposed noise levels, daily and total noise exposure time, and exposure to continuous noise. Occupational noise-induced tinnitus mainly causes emotional disability rather than physical disability. Emotionally impaired QOL results may be due to tinnitus-related psychological problems. Workers should have knowledge about the hazardous effects of noise. Periodic health checkups and regular seminars have great importance. Workers must be aware of other ototoxic factors, such as medications and noisy music. In the future, researchers should develop a screening method to detect those with a more hereditary affinity to hearing loss.

Bucher, T; van der Horst, K; Siegrist, M

2013-01-01

The present study assessed whether factual nutritional information on portion sizes helps consumers to select healthier meals. 124 people were invited to serve themselves lunch from a 'fake food buffet' containing 55 replica food items. Participants in the control group were instructed to serve themselves a meal, as they would normally eat from the given selections (control). Participants in the second condition were asked to select a healthy, balanced meal (instruction). People in the third group were also instructed to select a healthy meal, but in addition, they received nutrition information (instruction+information). The results suggest that participants in the instruction and instruction+information condition chose fewer sweets and desserts (F((2,121))=6.91, P<.05) but more fruits (F((2,121))=5.16, P<.05). This led to overall healthier meals than in the control group. All other food categories, including vegetables, were not altered. No difference was found between the two experimental groups. The results indicate that factual nutrition information does not help consumers compose healthier meals. Copyright © 2012 Elsevier Ltd. All rights reserved.

For the purpose of making a functional assessment of colostomy irrigation, eight patients were examined. Group A was composed of four patients whose experience of irrigation was less than one year. Group B was composed of four patients who had undergone irrigation for more than two years. The capacity of the remnant colon was determined by a barium enema. Next, 74 MBq of milking technetium 99 diethylene triamine penta-acetic acid (99mTc-DTPA) was instilled with a predetermined amount of water (37 degrees C). A dynamic scan was performed for 45 min. The mean evacuation time of Groups A and B were 6 min 56 s +/- 2 min 33 s and 13 min 27 s +/- 10 min 50 s, respectively. The mean half emptying time of Groups A and B were 142.5 s +/- 7.9 s and 309.0 s +/- 181.9 s. The results suggest that the remnant colon may be habituated with irrigation. Colostomy irrigation which uses a single instillation of a measured volume of tepid water is recommended.

Evaluate the bone tissue recovery following transplantation of ovine mesenchymal stem cells (MSC) from bone marrow and human immature dental-pulp stem cells (hIDPSC) in ovine model of induced osteonecrosis of femoral head (ONFH). Eight sheep were divided in three experimental groups. First group was composed by four animals with ONFH induced by ethanol through central decompression (CD), for control group without any treatment. The second and third group were compose by two animals, six weeks after ONFH induction received transplantation of heterologous ovine MSC (CD + oMSC), and hIDPSC (CD + hIDPSC), respectively. In both experiments the cells were transplanted without application of any type of immunosupression protocol. Our data indicate that both cell types used in experiments were able to proliferate within injured site providing bone tissue recovery. The histological results obtained from CD+hIDPSC suggested that the bone regeneration in such animals was better than that observed in CD animals. Mesenchymal stem cell transplant in induced ovine osteonecrosis of femoral head by central decompression technique is safe, and apparently favors bone regeneration of damaged tissues.

Coherence and incoherence collective behavior in financial market

2015-10-01

Financial markets have been extensively studied as highly complex evolving systems. In this paper, we quantify financial price fluctuations through a coupled dynamical system composed of phase oscillators. We find that a Financial Coherence and Incoherence (FCI) coexistence collective behavior emerges as the system evolves into the stable state, in which the stocks split into two groups: one is represented by coherent, phase-locked oscillators, the other is composed of incoherent, drifting oscillators. It is demonstrated that the size of the coherent stock groups fluctuates during the economic periods according to real-world financial instabilities or shocks. Further, we introduce the coherent characteristic matrix to characterize the involvement dynamics of stocks in the coherent groups. Clustering results on the matrix provides a novel manifestation of the correlations among stocks in the economic periods. Our analysis for components of the groups is consistent with the Global Industry Classification Standard (GICS) classification and can also figure out features for newly developed industries. These results can provide potentially implications on characterizing the inner dynamical structure of financial markets and making optimal investment into tragedies.

Sulfur metabolism in Escherichia coli and related bacteria: facts and fiction.

Sekowska, A; Kung, H F; Danchin, A

2000-04-01

Living organisms are composed of macromolecules made of hydrogen, carbon, nitrogen, oxygen, phosphorus and sulfur. Much work has been devoted to the metabolism of the first five elements, but much remains to be understood about sulfur metabolism. We review here the situation in Escherichia coli and related bacteria, where more than one hundred genes involved in sulfur metabolism have already been discovered in this organism. Examination of the genome suggests that many more will be found, especially genes involved in regulation, scavenging of sulfur containing molecules and synthesis of coenzymes or prosthetic groups. Furthermore, the involvement of methionine as the universal start of proteins as well as that of its derivative S-adenosylmethionine in a vast variety of cell processes argue in favour of a major importance of sulfur metabolism in all organisms.

Community structure in traffic zones based on travel demand

Sun, Li; Ling, Ximan; He, Kun; Tan, Qian

2016-09-01

Large structure in complex networks can be studied by dividing it into communities or modules. Urban traffic system is one of the most critical infrastructures. It can be abstracted into a complex network composed of tightly connected groups. Here, we analyze community structure in urban traffic zones based on the community detection method in network science. Spectral algorithm using the eigenvectors of matrices is employed. Our empirical results indicate that the traffic communities are variant with the travel demand distribution, since in the morning the majority of the passengers are traveling from home to work and in the evening they are traveling a contrary direction. Meanwhile, the origin-destination pairs with large number of trips play a significant role in urban traffic network's community division. The layout of traffic community in a city also depends on the residents' trajectories.

Natvig, Deborah; Tolbert, Sam

2005-01-01

The purpose of this study was to analyze utilization and costs of employer-sponsored health insurance in select businesses in a rural community in South Carolina. The study was conducted under the auspices of the HR Roundtable of the local Chamber of Commerce, composed of human resources directors from the larger area businesses. Twenty one companies were invited to participate and eight submitted information that was sufficiently complete to analyze. The participating companies employed 6,265 people, of which 5,712 were insured. The data represents a total of 13,057 covered lives. Although the findings cannot be generalized to a broader population, the descriptive data was sufficient to generate a discussion about health care issues for this community and for the group to make preliminary recommendations for collaborative work that may affect the costs of health care coverage for this community.

The study aims to develop a core set of pediatric drug-drug interaction (DDI) pairs for which electronic alerts should be presented to prescribers during the ordering process. A clinical decision support working group composed of Children's Hospital Association (CHA) members was developed. CHA Pharmacists and Chief Medical Information Officers participated. Consensus was reached on a core set of 19 DDI pairs that should be presented to pediatric prescribers during the order process. We have provided a core list of 19 high value drug pairs for electronic drug-drug interaction alerts to be recommended for inclusion as high value alerts in prescriber order entry software used with a pediatric patient population. We believe this list represents the most important pediatric drug interactions for practical implementation within computerized prescriber order entry systems.

One of the most completely preserved glacial sedimentary records from the Late Carboniferous to the Early Permian time corresponds to the Itararé Group, which presents a large outcropping thickness in the northeastern border of Paraná Basin, especially in the State of São Paulo. This unit corresponds to the base of the Gondwana I Supersequence and is composed of continental to marine glacial and interglacial deposits. Based on some macrofloristic, lithostratigraphic and palynostratigraphic data, a formal scheme of the macrofloral succession is herein proposed for this interval, comprising five associations in ascending stratigraphic order namely: (1) Dwykea-Sublagenicula-Calamospora Association (recorded in Campinas Municipality), composed of lycophyte megaspores (Sublagenicula, Trileites and Calamospora sp.) and some bryophytes (Dwykea), concerning to a coastal glacial or coastal interglacial environment; (2) Eusphenopteris-Nothorhacopteris-Botrychiopsis Association (registered in Itapeva and Buri municipalities), composed of Eusphenopteris, Nothorhacopteris, Botrychiopsis, Paracalamites spp. along with Sphenophyllum, Koretrophyllites, Noeggerathiopsis and rare Cordaicarpus and Samaropsis - concerning to an interglacial deltaic plain associated to coal forming swamps with cold temperate hydro-hygrophilous vegetation; (3) Paranocladus-Ginkgophyllum-Brasilodendron Association (registered in Monte Mor Municipality), composed of the first conifers of the Paraná Basin (Paranocladus, Paranospermum and few Buriadia-type), lycophytes (Brasilodendron, Bumbudendron), Ginkgophyllum, Noeggerathiopsis, Samaropsis and Cordaicarpus and rare Nothorhacopteris, Botrychiopsis, Koretrophyllites and Sphenophyllum, interpreted as interglacial deltaic flood plain; (4) Dwykea-Sublagenicula-Calamospora Recurrent Association (recorded in Salto Municipality), composed of bryophytes (Dwykea) and lycopod megaspores, very similar to the first association, related to a coastal glacial or coastal interglacial depositional environment with a type- tundra vegetational cover; and (5) Gangamopteris-Arberia-Stephanophyllites Association (occurring in Tietê and Cerquilho municipalities), composed of the first glossopterid leaves and fructifications of the Paraná Basin (abundant Gangamopteris, Arberia, Arberiopsis and Hirsutum) and sphenophytes (Stephanophyllites and Phyllotheca), suggested as coastal prograding or alluvial environment, of an interglacial phase at the end of the sedimentary history of the Itararé Group. The first four associations are of Pennsylvanian age while the last one is of Asselian-Sakmarian age.

What Models of Verbal Working Memory Can Learn from Phonological Theory: Decomposing the Phonological Similarity Effect

Innovation Through Tradition: Rediscovering the "Humanist" in the Medical Humanities.

Kutac, Julie; Osipov, Rimma; Childress, Andrew

2016-12-01

Throughout its fifty-year history, the role of the medical humanist and even the name "medical humanities" has remained raw, dynamic and contested. What do we mean when we call ourselves "humanists" and our practice "medical humanities?" To address these questions, we turn to the concept of origin narratives. After explaining the value of these stories, we focus on one particularly rich origin narrative of the medical humanities by telling the story of how a group of educators, ethicists, and scholars struggling to define their relatively new field rediscovered the studia humanitatis, a Renaissance curriculum for learning and teaching. Our origin narrative is composed of two intertwined stories-the history of the studia humanitatis itself and the story of the scholars who rediscovered it. We argue that as an origin narrative the studia humanitatis grounds the medical humanities as both an engaged moral practice and pedagogical project. In the latter part of the paper, we use this origin narrative to show how medical humanists working in translational science can use their understanding of their historical roots to do meaningful work in the world.

The main goal of the presented work was to evolve a multifunctional beam composed out of fiber reinforced plastics (FRP) and an embedded optical fiber with various fiber Bragg grating sensors (FBG). These beams are developed for the use as structural member for bridges or industrial applications. It is now possible to realize large scale cross sections, the embedding is part of a fully automated process and jumpers can be omitted in order to not negatively influence the laminate. The development includes the smart placement and layout of the optical fibers in the cross section, reliable strain transfer, and finally the coupling of the embedded fibers after production. Micromechanical tests and analysis were carried out to evaluate the performance of the sensor. The work was funded by the German ministry of economics and technology (funding scheme ZIM). Next to the authors of this contribution, Melanie Book with Röchling Engineering Plastics KG (Haren/Germany; Katharina Frey with SAERTEX GmbH & Co. KG (Saerbeck/Germany) were part of the research group.

Education on electrical phenomena involved in electroporation-based therapies and treatments: a blended learning approach.

Čorović, Selma; Mahnič-Kalamiza, Samo; Miklavčič, Damijan

2016-04-07

Electroporation-based applications require multidisciplinary expertise and collaboration of experts with different professional backgrounds in engineering and science. Beginning in 2003, an international scientific workshop and postgraduate course electroporation based technologies and treatments (EBTT) has been organized at the University of Ljubljana to facilitate transfer of knowledge from leading experts to researches, students and newcomers in the field of electroporation. In this paper we present one of the integral parts of EBTT: an e-learning practical work we developed to complement delivery of knowledge via lectures and laboratory work, thus providing a blended learning approach on electrical phenomena involved in electroporation-based therapies and treatments. The learning effect was assessed via a pre- and post e-learning examination test composed of 10 multiple choice questions (i.e. items). The e-learning practical work session and both of the e-learning examination tests were carried out after the live EBTT lectures and other laboratory work. Statistical analysis was performed to compare and evaluate the learning effect measured in two groups of students: (1) electrical engineers and (2) natural scientists (i.e. medical doctors, biologists and chemists) undergoing the e-learning practical work in 2011-2014 academic years. Item analysis was performed to assess the difficulty of each item of the examination test. The results of our study show that the total score on the post examination test significantly improved and the item difficulty in both experimental groups decreased. The natural scientists reached the same level of knowledge (no statistical difference in total post-examination test score) on the post-course test take, as do electrical engineers, although the engineers started with statistically higher total pre-test examination score, as expected. The main objective of this study was to investigate whether the educational content the e-learning practical work presented to the students with different professional backgrounds enhanced their knowledge acquired via lectures during EBTT. We compared the learning effect assessed in two experimental groups undergoing the e-learning practical work: electrical engineers and natural scientists. The same level of knowledge on the post-course examination was reached in both groups. The results indicate that our e-learning platform supported by blended learning approach provides an effective learning tool for populations with mixed professional backgrounds and thus plays an important role in bridging the gap between scientific domains involved in electroporation-based technologies and treatments.

Acanthamoebidae is a "family" level amoebozoan group composed of the genera Acanthamoeba, Protacanthamoeba, and very recently Luapeleamoeba. This clade of amoebozoans has received considerable attention from the broader scientific community as Acanthamoeba spp. represent both model organisms and human pathogens. While the classical composition of the group (Acanthamoeba + Protacanthamoeba) has been well accepted due to the morphological and ultrastructural similarities of its members, the Acanthamoebidae has never been highly statistically supported in single gene phylogenetic reconstructions of Amoebozoa either by maximum likelihood (ML) or Bayesian analyses. Here we show using a phylogenomic approach that the Acanthamoebidae is a fully supported monophyletic group within Amoebozoa with both ML and Bayesian analyses. We also expand the known range of morphological and life cycle diversity found in the Acanthamoebidae by demonstrating that the amoebozoans "Protostelium" arachisporum, Dracoamoeba jormungandri n. g. n. sp., and Vacuolamoeba acanthoformis n.g. n.sp., belong within the group. We also found that "Protostelium" pyriformis is clearly a species of Acanthamoeba making it the first reported sporocarpic member of the genus, that is, an amoeba that individually forms a walled, dormant propagule elevated by a non-cellular stalk. Our phylogenetic analyses recover a fully supported Acanthamoebidae composed of five genera. Two of these genera (Acanthamoeba and Luapeleameoba) have members that are sporocarpic. Our results provide high statistical support for an Acanthamoebidae that is composed of five distinct genera. This study increases the known morphological diversity of this group and shows that species of Acanthamoeba can include spore-bearing stages. This further illustrates the widespread nature of spore-bearing stages across the tree of Amoebozoa. This article was reviewed by Drs. Eugene Koonin, Purificacion Lopez-Garcia and Sandra Baldauf.

Structure and function of archaeal prefoldin, a co-chaperone of group II chaperonin.

PubMed

Ohtaki, Akashi; Noguchi, Keiichi; Yohda, Masafumi

2010-01-01

Molecular chaperones are key cellular components involved in the maintenance of protein homeostasis and other unrelated functions. Prefoldin is a chaperone that acts as a co-factor of group II chaperonins in eukaryotes and archaea. It assists proper folding of protein by capturing nonnative proteins and delivering it to the group II chaperonin. Eukaryotic prefoldin is a multiple subunit complex composed of six different polypeptide chains. Archaeal prefoldin, on the other hand, is a heterohexameric complex composed of two alpha and four beta subunits, and forms a double beta barrel assembly with six long coiled coils protruding from it like a jellyfish with six tentacles. Based on the structural information of the archaeal prefoldin, substrate recognition and prefoldin-chaperonin binding mechanisms have been investigated. In this paper, we review a series of studies on the molecular mechanisms of archaeal PFD function. Particular emphasis will be placed on the molecular structures revealed by X-ray crystallography and molecular dynamics induced by binding to nonnative protein substrates.

Mapping young stellar populations towards Orion with Gaia DR1

OB associations are prime sites for the study of star formation processes and of the interaction between young massive stars with the interstellar medium. Furthermore, the kinematics and structure of the nearest OB associations provide detailed insight into the properties and origin of the Gould Belt. In this context, the Orion complex has been extensively studied. However, the spatial distribution of the stellar population is still uncertain: in particular, the distances and ages of the various sub-groups composing the Orion OB association, and their connection to the surrounding interstellar medium, are not well determined. We used the first Gaia data release to characterize the stellar population in Orion, with the goal to obtain new distance and age estimates of the numerous stellar groups composing the Orion OB association. We found evidence of the existence of a young and rich population spread over the entire region, loosely clustered around some known groups. This newly discovered population of young stars provides a fresh view of the star formation history of the Orion region.

In today's challenging healthcare environment, clinicians need to understand the fundamentals of financial analysis, which are the underpinnings of their clinical programs, especially when seeking administrative support for new initiatives. The business plan for new clinical program initiatives is composed of diverse elements such as the mission statement, market and competitive analyses, operations plan, and financial analysis. Armed with a basic knowledge of financial analysis of clinical programs, as well as forward-looking analysis of an initiative's added value, the healthcare provider can work much more effectively with administration in developing or creating new healthcare program initiatives.

Experience with pornography: Rapists, pedophiles, homosexuals, transsexuals, and controls.

An interview designed to assess a respondent's experience with erotic material in photographs, films, and books, during adolescence and adulthood, was administered to convicted male rapists, pedophiles, homosexuals, transsexuals, heavy pornography users, and two nondeviant contrast groups. One nondeviant group was composed of whites matched for the sex offender group; the other was composed of ghetto and middle-class blacks. Adolescent exposure to erotica was significantly less for all deviant and offender groups compared to the nondeviants. During adulthood, the sex offenders and transsexuals continued to report less exposure to erotic stimuli than controls. The homosexuals and users, however, both report greater exposure during adulthood. As adolescents, the control group, rapists, and heavy users were excited to masturbate by the erotic materials more than the other groups. As adults, the controls and rapists showed a sharp decrease in being excited to masturbate to erotica while the users' rate remained high and the homosexuals' rate rose. Less than a quarter of the respondents in any group imitated sexual behavior seen in the erotic material immediately or shortly after its viewing. The hypothesis that extent of exposure during adolescence to erotica is positively associated with the later emergence of sexual pathology is not borne out by this study. The nondeviant, non-sex-offender groups sampled had had significantly greater exposure to erotic materials during adolescence than the deviants, convicted sex offenders, or heavy adult users of pornography.

Characterization of PSII-LHCII supercomplexes isolated from pea thylakoid membrane by one-step treatment with α- and β-dodecyl-D-maltoside.

It was the work of Jan Anderson, together with Keith Boardman, that showed it was possible to physically separate photosystem I (PSI) from photosystem II (PSII), and it was Jan Anderson who realized the importance of this work in terms of the fluid-mosaic model as applied to the thylakoid membrane. Since then, there has been a steady progress in the development of biochemical procedures to isolate PSII and PSI both for physical and structural studies. Dodecylmaltoside (DM) has emerged as an effective mild detergent for this purpose. DM is a glucoside-based surfactant with a bulky hydrophilic head group composed of two sugar rings and a non-charged alkyl glycoside chain. Two isomers of this molecule exist, differing only in the configuration of the alkyl chain around the anomeric centre of the carbohydrate head group, axial in α-DM and equatorial in β-DM. We have compared the use of α-DM and β-DM for the isolation of supramolecular complexes of PSII by a single-step solubilization of stacked thylakoid membranes isolated from peas. As a result, we have optimized conditions to obtain homogeneous preparations of the C(2)S(2)M(2) and C(2)S(2) supercomplexes following the nomenclature of Dekker & Boekema (2005 Biochim. Biophys. Acta 1706, 12-39). These PSII-LHCII supercomplexes were subjected to biochemical and structural analyses.

Five scientists at MSFC/ESAD have EOS SCF investigator status. Each SCF has unique tasks which require the establishment of a computing facility dedicated to accomplishing those tasks. A SCF Working Group was established at ESAD with the charter of defining the computing requirements of the individual SCFs and recommending options for meeting these requirements. The primary goal of the working group was to determine which computing needs can be satisfied using either shared resources or separate but compatible resources, and which needs require unique individual resources. The requirements investigated included CPU-intensive vector and scalar processing, visualization, data storage, connectivity, and I/O peripherals. A review of computer industry directions and a market survey of computing hardware provided information regarding important industry standards and candidate computing platforms. It was determined that the total SCF computing requirements might be most effectively met using a hierarchy consisting of shared and individual resources. This hierarchy is composed of five major system types: (1) a supercomputer class vector processor; (2) a high-end scalar multiprocessor workstation; (3) a file server; (4) a few medium- to high-end visualization workstations; and (5) several low- to medium-range personal graphics workstations. Specific recommendations for meeting the needs of each of these types are presented.

Work in catering and food processing is mostly performed by hands. Mechanical, thermal and chemical agents, as well as damp working conditions and frequent hand washing aggravate skin irritation. The aim of the study was to test the efficacy of hydrophobic skin protection measure at these workplaces. We recommended the prevention of contact skin disorders by using hydrophobic skin protection measure. The study was conducted in a group of 20 food service sector workers, They were interviewed about skin problems and skin protection measures. Tolb assess the effect of the protective preparation on the skin dermatological test procedures, corneometry and sebumetry, were applied, as well as the level of transepidermal water loss (TEWL) was measured. The same survey was performed in the control group composed of 10 workers who used and 10 who did not use barrier preparation. The respondents declared dryness, roughness, peeling, burning, redness, erythema of the skin. All who had applied barrier cream observed a significant improvement of the skin hydration increased by about 30%, and lubrication of the skin - by 11 times on average. Also the level of TEWL decreased by about 25%. The improvement of skin conditions and reduction of skin disorders were observed confirming the effectiveness of the protection of the skin from exposure to harmful factors. Knowledge about prevention of skin diseases should be promoted among employees of catering enterprises.

In January, 1984, the American College of Radiology (ACR) representing the users of imaging equipment and the National Electrical Manufacturers Association (NEMA) representing the manufacturers of imaging equipment joined forces to create a committee that could solve the compatibility issues surrounding the exchange of digital medical images. This committee, the ACR-NEMA Digital Imaging and Communication Standards Committee was composed of radiologists and experts from industry who addressed the problems involved in interfacing different digital imaging modalities. In just two years, the committee and three of its working groups created an industry standard interface, ACR-NEMA Digital Imaging and Communications Standard, Publication No. 300-1985. The ACR-NEMA interface allows digital medical images and related information to be communicated between different imaging devices, regardless of manufacturer or use of differing image formats. The interface is modeled on the International Standards Organization's Open Systems Interconnection sever-layer reference model. It is believed that the development of the Interface was the first step in the development of standards for Medical Picture Archiving and Communications Systems (PACS). Developing the interface Standard has required intensive technical analysis and examination of the future trends for digital imaging in order to design a model which would not be quickly outmoded. To continue the enhancement and future development of image management systems, various working groups have been created under the direction of the ACR-NEMA Committee.

Coupling and Reactions of 5-Hydroxyconiferyl Alcohol in Lignin Formation.

Elder, Thomas; Berstis, Laura; Beckham, Gregg T; Crowley, Michael F

2016-06-15

The catechol alcohols, caffeyl and 5-hydroxyconiferyl alcohol, may be incorporated into lignin either naturally or through genetic manipulation. Due to the presence of o-OH groups, these compounds form benzodioxanes, a departure from the interunit connections found in lignins derived from the cinnamyl alcohols. In nature, lignins composed of caffeyl and 5-hydroxyconiferyl alcohol are linear homopolymers and, as such, may have properties that make them amenable for use in value-added products, such as lignin-based carbon fibers. In the current work, results from density functional theory calculations for the reactions of 5-hydroxyconiferyl alcohol, taking stereochemistry into account, are reported. Dehydrogenation and quinone methide formation are found to be thermodynamically favored for 5-hydroxyconiferyl alcohol, over coniferyl alcohol. The comparative energetics of the rearomatization reactions suggest that the formation of the benzodioxane linkage is under kinetic control. Ring-opening reactions of the benzodioxane groups show that the bond dissociation enthalpy of the α-O cleavage reaction is lower than that of the β-O reaction. The catechol lignins represent a novel form of the polymer that may offer new opportunities for bioproducts and genetic targets.

The role of ocean phenomenon in music compositions

This is a preliminarily interdisciplinary study for exploring the elements of ocean phenomenon appearing in some compositions of classical music. The so-called ocean phenomenon contain wave conditions, climate change, coastal landform, and other natural events around or over the sea. In some music compositions, it is apparent that natural phenomenon over the sea influence the composers' moods and the music pieces they composed. In this poster, some music compositions in the 19th and the early 20th centuries will be introduced to demonstrate the relation between ocean and music works. These works include Meeresstille by Schubert, Étude Op.25 No.12 by Chopin, Fingal's Cave Overture by Mendelssohn, Der Fliegende Holländer by Wagner and La Mer by Debussy. In addition, present idea may give a novel way for music teachers to elucidate the knowledge of ocean science in classes.

MO-A-BRD-05: Evaluation of Composed Lung Ventilation with 4DCT and Image Registration

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

Du, K; Bayouth, J; Reinhardt, J

Purpose: Regional pulmonary function can be derived using fourdimensional computed tomography (4DCT) combined with deformable image registration. However, only peak inhale and exhale phases have been used thus far while the lung ventilation during intermediate phases is not considered. In our previous work, we have investigated the spatiotemporal heterogeneity of lung ventilation and its dependence on respiration effort. In this study, composed ventilation is introduced using all inspiration phases and compared to direct ventilation. Both methods are evaluated against Xe-CT derived ventilation. Methods: Using an in-house tissue volume preserving deformable image registration, unlike the direct ventilation method, which computes frommore » end expiration to end inspiration, Jacobian ventilation maps were computed from one inhale phase to the next and then composed from all inspiration steps. The two methods were compared in both patients prior to RT and mechanically ventilated sheep subjects. In addition, they wereassessed for the correlation with Xe-CT derived ventilation in sheep subjects. Annotated lung landmarks were used to evaluate the accuracy of original and composed deformation field. Results: After registration, the landmark distance for composed deformation field was always higher than that for direct deformation field (0IN to 100IN average in human: 1.03 vs 1.53, p=0.001, and in sheep: 0.80 vs0.94, p=0.009), and both increased with longer phase interval. Direct and composed ventilation maps were similar in both sheep (gamma pass rate 87.6) and human subjects (gamma pass rate 71.9),and showed consistent pattern from ventral to dorsal when compared to Xe-CT derived ventilation. Correlation coefficient between Xe-CT and composed ventilation was slightly better than the direct method but not significant (average 0.89 vs 0.85, p=0.135). Conclusion: More strict breathing control in sheep subjects may explain higher similarity between direct and composed ventilation. When compared to Xe-CT ventilation, no significant difference was found for the composed method. NIH Grant: R01 CA166703.« less

The role of atrial fibrillation (AF) in older patients with heart failure (HF) is controversial because many variables seem to influence their outcome. We investigated the predictivity of AF in 3 age groups of outpatients with HF. We analyzed 8,178 outpatients enrolled in the Italian Network on Congestive Heart Failure Registry with HF diagnosed according to the European Society of Cardiology criteria. A trained cardiologist established the diagnosis of AF and HF at the entry visit at each center. We stratified the population into 3 age groups, as follows: group A, < or =65 years; group B, 66-75 years, and group C, >75 years. Group A was composed of 4,261 patients, 683 with AF (16.0%); in group B there were 2,651 patients, 638 with AF (24.1%), and group C was composed of 1,266 patients, 412 with AF (32.5%). The 1-year mortality rate was higher in AF patients in all groups. In a multivariate model, AF remained an independent risk factor for death in groups A and B, but not in group C [group A: hazard ratio (HR) 1.42, 95% confidence interval (CI) 1.10-1.81; group B: HR 1.29, 95% CI 1.00-1.67; group C: HR 1.05, 95% CI 0.78-1.43]. The prevalence of AF increased with age and was associated with a higher mortality rate. However, AF independently predicted all-cause mortality only in patients aged < or =75 years.

Early language development in children with profound hearing loss fitted with a device at a young age: part II--content of the first lexicon.

2009-10-01

Lexical content is commonly understood to refer to the various categories of words that children produce and has been studied extensively in children with normal hearing. Unlike the hearing child, however, little is known about the word categories that make up the first lexicon of children with hearing loss (HL). Knowledge of the first lexicon is increasingly important, as infants with HL are now being detected through universal newborn hearing screening programs and fitted with hearing aids and cochlear implants in before 12 months of age. For these children, emergence of the first spoken words is a major milestone eagerly awaited by parents and one of the first verbal language goals of teachers and therapists working with such children. The purpose of this study was to evaluate the lexical content of the first 50 and 100 words produced by children with HL and to contrast this with that of a group of hearing children. Lexical content was compared in two groups of children: one group composed of 24 participants with severe profound or profound HL and a second group composed of 16 participants with normal hearing. Twenty-three participants in the HL group were fitted with a cochlear implant and one with bilateral hearing aids. All were "switched on" or fitted before 30 months of age. The Diary of Early Language (Di-EL) was used to collect a 100-word lexicon from each participant. All single word and frozen phrase data from each child's Di-EL were allocated to 1 of 15 word types grouped into four word categories (noun, predicate, grammatical, and paralexical), and the results were compared for both groups. The hearing and HL groups showed similar distributions of word categories, with nouns constituting the largest portion of the lexicon followed by predicates and paralexicals. Grammaticals made up the smallest portion of the lexicon. However, several significant differences were evident between the two groups. In both the 50- and 100-word lexicons, the hearing group used proportionately more nouns, fewer predicates, more common nouns, and fewer onomatopoeic words compared with the HL group. Further, more participants in the hearing group used grammatical word types other than adverbs (including pronouns) compared with the HL group. Overall, lexical content of the HL group was similar to that of the hearing group for both the 50- and 100-word lexicons, although some differences in proportional use were noted across word categories and types. It is suggested that differences in the quantity and diversity of language experienced by children with normal hearing compared with those with HL, together with differences in the input they receive, might in part explain these differences. The effect of quality of speech input and therapy method on the emerging lexicon and subsequent language development will be particularly important in informing appropriate intervention strategies for children with HL.

All of the participants were initially assessed by the ABFW Test - Phonology. After that, they were assessed on their lexical and metaphonological abilities by the ABFW Test - Vocabulary and phonological awareness test: sequential assessment instrument, CONFIAS - identification tasks and, rhyme and alliteration production, respectively. regarding lexical ability, the preschoolers from both groups presented similar behavior. The disordered preschoolers presented the worst performance on the overall analysis of the metaphonological ability. Age had an influence on the performance of lexical ability for both groups and the metaphonological abilities only for the Control Group. Correlations were identified, mostly positive, good to moderate between lexical and metaphonological abilities. the influence of Phonological Disorder may only be observed on the metaphonological performance. Phonological Disorder did not interfere with the development of the lexical ability of this group of preschoolers. Positive correlations were identified between both abilities in the studied age group.

Women and Couples in Isolated Extreme Environments: Applications for Long-Duration Missions

NASA Astrophysics Data System (ADS)

Leon, G. R.; Sandal, G. M.

Analysis of the functioning of different types of expedition teams provides a range of analogs from which to make judgments about human limitations during long-duration space exploration, and possible countermeasures for dealing with these problems. Some of the limitations identified are the tendency for participants in all-male groups to be higWy competitive and unlikely to share personal concerns with each other. Women in mixed-gender groups often experience interpersonal stress because male team members confide concerns to them, although not necessarily encouraging reciprocal sharing. Women have also been found to take the role of "peacemakers", reducing competition and tension among male participants. Three multinational polar expedition groups were studied that varied in crew composition and nature of the environmental and work conditions. Group 1 consisted of two women who skied the length of the Antarctic continent on a 97 day traverse, hauling sleds weighing up to 114 kg. The participants were highly compatible in interests and prior expedition experience, and in appreciation of the knowledge and judgment of their partner. Assessment measures were as follows: Multidimensional Personality Inventory (MPQ), Personality Characteristics Inventory (PCI), and Utrecht Coping List (UCL) completed prior to the expedition; Weekly Rating Form (WRF) examining intra/interpersonal variables, work performance, and environmental factors during the trek; semi-structured interview conducted at the end of the expedition. Roth team members scored relatively high on the MPQ personality trait of Absorption; they also were classified as "the right stuff' based on PCI findings. Bach provided emotional support to her teammate during difficult times, yet respected the others' autonomy and self -esteem. A dyadic process of shared cognition was evident in the substantial similarities in approach to solving problems, and the cooperative nature of decision making. Group 2 was composed of four women from Greenland, Denmark, UK and Russia who traversed the Greenland ice by ski. The participants did not know each other prior to the expedition. Three were classified as "the right stuff' based on PCI findings. Diary and post-expedition reports indicated that incidents of interpersonal tension were often related to fatigue, homesickness, pain or cold. The participants also indicated that respect and tolerance for differences between them, as weIl as mutual emotional support were crucial factors for the successful completion of the expedition. Group 3 consisted of 3 married couples and the 2 1/2 year old child of the leader and his wife. Five of the crew sailed a small boat from Norway to the Canadian High Arctic; the leader's wife and child joined the team in Greenland. Over a 9 month period, the icelocked boat was ilie center of habitation, scientific, and other activities. Three of the group carried out a 6 week exploratory trek at the end of the winter-over. Participants completed the MPQ prior to the expedition, a WRF over the entire Arctic period, and a semi-structured personality interview at the close of the interval during which the entire group was together. AlI participants scored relatively highest on the Absorption scale, manifested in the salutory experience of enjoying and becoming engrossed in the beauty of the environment. WRF and interview findings indicated that team members consistently reported that the emotional support of and ability to confide in their partner were extremely important in alleviating interpersonal tensions with other team members, and contributed to the overall effective functioning of the group. Reported level of emotional response to stress and coping patterns used while in the stationary habitat were consistent with WRF responses during the later exploratory trek. The woman team member on the trek reported more discomfort regarding personal hygiene issues and fear of injury .In alI groups, the salience of the overriding goal of the expedition was a highly important factor in coping and striving for optimal work performance. Maintainil}g the self-esteem of each group member at difficult times such as injury or psychological stress is also very important for optimal work performance and mission success. Women appear to add an element of emotional support and help to other team members that is not as evident in all-male groups. However, the need for women in these groups to also have a confidant with whom to share concerns may increase the overall efficiency of isolated groups. The effectiveness of the decision-making processes by co-equal partners suggests a viable alternative for planetary exploration than the usual military command structure. Moreover, a group composed of couples with strong bonds with their partner is another paradigm to consider for crew selection for long-duration missions.

expressive language of pre-term children. to compare the expressive vocabulary of two year-old children born prematurely, to that of those born at term. the study sample was composed by 118 speech-language assessment protocols, divided in two groups: the pre-term group (PTG) composed by 58 underweight premature children followed by a multi-professional team at the Casa do Prematuro (House of Premature Children) at Unifesp, and the full-term group (FTG) composed by 60 full-term born children. In order to evaluate the expressive language of these children, the Lave - Lista de Avaliação do Vocabulário Expressivo (Assessment List of the Expressive Vocabulary) was used. The Lave is an adaptation of the LDS - Language Development Survey - for the Brazilian Portuguese Language. The Lave investigates the expressive language and detects delays in oral language. children born underweight and prematurely present a greater occurrence of expressive language delay, 27.6%. These pre-term children present significantly lower expressive vocabulary and phrasal extension than children of the same age born at full-term in all semantic categories. Family income proved to be positively associated to phrasal extension, as well as to gestational age and weight at birth; thus indicating the effect of these adverse conditions still during the third year of age. The audiological status was associated to word utterances in the PTG. children born prematurely and underweight are at risk in terms of vocabulary development; this determines the need for speech-therapy intervention programs.

Music and 're-education' in the Soviet Gulag.

PubMed

Klause, Inna

2013-01-01

After the October Revolution, the Bolsheviks announced a new human dimension of penal policy whose goal should be the so-called 're-education' of prisoners. The desired 're-education' was to be realised using two kinds of measures: the physical work of the prisoners, and 'cultural education work'. A varied musical life in groups, 'agitation brigades', ensembles, orchestras and choirs developed within the framework of the 'cultural education work'. Two camps responsible for building canals in the 1930s particularly adopted this musical life: Belbaltlag and Dmitlag. In the latter, a composition competition took place in 1936 in which, among others, the arrested composer Sergey Protopopov took part. Since the 1930s, the Gulag administration had publicised that the measures taken for 're-education' concerned primarily criminal prisoners, as opposed to 'political prisoners', who were labelled as foreign to socialist society. Although the 'cultural education work' would not have functioned as well as it did without the cooperation of 'political prisoners', since their participation did not fit into the prescribed ideology, they were often underappreciated or even completely concealed. The following is a depiction of the officially organised musical life in the Gulag in the 1920s and 1930s as a grey zone. Music making and listening represented not only a source of strength for the prisoners, but also brought about situations that meant physical and psychological torture for them.

This work aims at presenting the main results achieved by Working Group (WG) 2 "GPR surveying of pavements, bridges, tunnels and buildings; underground utility and void sensing" of the COST (European COoperation in Science and Technology) Action TU1208 "Civil Engineering Applications of Ground Penetrating Radar" (www.GPRadar.eu, www.cost.eu). The principal goal of the Action, started in April 2013 and ending in October 2017, is to exchange and increase scientific-technical knowledge and experience of Ground Penetrating Radar (GPR) techniques in civil engineering, whilst promoting throughout Europe the effective use of this safe non-destructive technique. The Action involves more than 300 Members from 28 COST Countries, a Cooperating State, 6 Near Neighbour Countries and 6 International Partner Countries. The most interesting achievements of WG2 include: 1. The state of the art on the use of GPR in civil engineering was composed and open issues were identified. The few existing international/national guidelines/protocols for GPR inspection in civil engineering were reviewed and discussed. Academic end-users, private companies and stakeholders presented their point of view and needs. 2. Guidelines for investigating flexible pavement by using GPR were prepared, with particular regard to layer-thickness assessment, moisture-content sensing, pavement-damage detection and classification, and other main GPR-based investigations in pavement engineering. 3. Guidelines for GPR sensing and mapping of underground utilities and voids were prepared, with a main focus on urban areas. 4. Guidelines for GPR assessment of concrete structures, with particular regard to inspections in bridges and tunnels, were prepared. 5. A report was composed, including a series of practical suggestions and very useful information to guide GPR users during building inspection. 6. WG2 Members carried out a plethora of case studies where GPR was used to survey roads, highways, airport runways, car parkings, road tunnels, underground concrete tunnels, bridges, railways, buildings. GPR was also employed to detect cables and pipes, as well as to inspect road construction materials, joints, concrete and wood. A selection of the most interesting results will be presented during the 2017 EGU GA. 7. WG2 contributed to the TU1208 Education Pack, an open-access educational package conceived to teach GPR in University courses. 8. In cooperation with the other Working Groups, WG2 organized Tutorials on Ground Penetrating Radar (Brussels, Belgium, July 2014, and London, United Kingdom, March 2015), as well as Training Schools on "Civil engineering applications of Ground Penetrating Radar" (Pisa, Italy, September 2014), "Applications of Ground Penetrating Radar in urban areas: the sensitive case of historical cities" (Cracow, Poland, May 2015), "Ground Penetrating Radar for road pavement assessment and detection of buried utilities" (London, United Kingdom, October 2015), "Applications of GPR to civil engineering and archaeology" (Valletta, Malta, January 2016), "Non-destructive testing techniques for civil engineering" (Barcelona, Spain, March 2016), and finally "Ground Penetrating Radar for the assessment of transport infrastructure" (Osijek, Croatia, March 2017). 9. In cooperation with the other Working Groups, WG2 organized a series of national events devoted to fostering the interaction with stakeholders, new potential GPR end-users, and interested citizens. During such events, participants could discover what is GPR and how this technique can be effectively used in civil engineering works as well as in different fields ("TU1208 GPR Road Show").

Many science projects in the future will be accomplished through collaboration among 2 or more NASA centers along with, potentially, external scientists. Science teams will be composed of more geographically dispersed individuals and groups. However, the current computing environment does not make this easy and seamless. By being able to share computing resources among members of a multi-center team working on a science/ engineering project, limited pre-competition funds could be more efficiently applied and technical work could be conducted more effectively with less time spent moving data or waiting for computing resources to free up. Based on the work from an NASA CIO IT Labs task, this presentation will highlight our prototype work in identifying the feasibility and identify the obstacles, both technical and management, to perform "Cloudbursting" among private clouds located at three different centers. We will demonstrate the use of private cloud computing infrastructure at the Jet Propulsion Laboratory, Langley Research Center, and Ames Research Center to provide elastic computation to each other to perform parallel Earth Science data imaging. We leverage elastic load balancing and auto-scaling features at each data center so that each location can independently define how many resources to allocate to a particular job that was "bursted" from another data center and demonstrate that compute capacity scales up and down with the job. We will also discuss future work in the area, which could include the use of cloud infrastructure from different cloud framework providers as well as other cloud service providers.

The family Mimiviridae, comprised by giant DNA viruses, has been increasingly studied since the isolation of the Acanthamoeba polyphaga mimivirus (APMV), in 2003. In this work, we describe the genome analysis of two new mimiviruses, each isolated from a distinct Brazilian environment. Furthermore, for the first time, we are reporting the genomic characterization of mimiviruses of group C in Brazil (Br-mimiC), where a predominance of mimiviruses from group A has been previously reported. The genomes of the Br-mimiC isolates Mimivirus gilmour (MVGM) and Mimivirus golden (MVGD) are composed of double-stranded DNA molecules of ∼1.2 Mb, each encoding more than 1,100 open reading frames. Genome functional annotations highlighted the presence of mimivirus group C hallmark genes, such as the set of seven aminoacyl-tRNA synthetases. However, the set of tRNA encoded by the Br-mimiC was distinct from those of other group C mimiviruses. Differences could also be observed in a genome synteny analysis, which demonstrated the presence of inversions and loci translocations at both extremities of Br-mimiC genomes. Both phylogenetic and phyletic analyses corroborate previous results, undoubtedly grouping the new Brazilian isolates into mimivirus group C. Finally, an updated pan-genome analysis of genus Mimivirus was performed including all new genomes available until the present moment. This last analysis showed a slight increase in the number of clusters of orthologous groups of proteins among mimiviruses of group A, with a larger increase after addition of sequences from mimiviruses of groups B and C, as well as a plateau tendency after the inclusion of the last four mimiviruses of group C, including the Br-mimiC isolates. Future prospective studies will help us to understand the genetic diversity among mimiviruses. PMID:29312242

Penetration of HIV-1 Tat47-57 into PC/PE Bilayers Assessed by MD Simulation and X-ray Scattering.

The interactions of the basic, cell-penetrating region (Y47GRKKRRQRRR57) of the HIV-1 Tat protein with dioleoylphosphatidylcholine (DOPC) bilayers were previously assessed by comparing experimental X-ray diffuse scattering with atomistic molecular dynamics simulations. Here, we extend this investigation by evaluating the influence of phosphatidylethanolamine (PE) lipids. Using experimental bilayer form factors derivedfrom X-ray diffuse scattering data as a guide, our simulations indicate that Tat peptides localize close to the carbonyl-glycerol group in the headgroup region of bilayers composed of either DOPC or DOPC:DOPE (1:1) lipid. Our results also suggest that Tat peptides may more frequently insert into the hydrophobic core of bilayers composed of PC:PE (1:1) lipids than into bilayers composed entirely of PC lipids. PE lipids may facilitate peptide translocation across a lipid bilayer by stabilizing intermediate states in which hydrated peptides span the bilayer.

An ability-focused battery (AFB) is a selected group of well-validated neuropsychological measures that assess the conventional range of cognitive domains. This study examined the diagnostic efficiency of an AFB for use in clinical decision making with a mixed sample composed of individuals with neurological brain dysfunction and individuals referred for cognitive assessment without evidence of neurological disorders. Using logistic regression analyses and ROC curve analysis, a five-domain model composed of attention, processing speed, visual-spatial reasoning, language/verbal reasoning, and memory domain scores was fitted that had an AUC of.89 (95% CI =.84-.95). A more parsimonious two-domain model using processing speed and memory was also fitted that had an AUC of.90 (95% confidence interval =.84-.95). A model composed of a global ability score calculated from the mean of the individual domain scores was also fitted with an AUC of.88 (95% CI =.82-.94).

Helete formation is located at Adiyaman, Turkey which is in the Alpine-Himalayan orogeny belt. Helete formation is represented by andesitic, basaltic and gabbroic rocks cut by localized felsic intrusions and overlain by open-marine Nummulitic carbonate sediments. Electron microprobe analyses were conducted for 15 rocks samples of Helete formation. These rock samples are named as basalt, andesite, gabbro, diorite, dacite, and granite. Basalt and andesite samples are composed of clinopyroxene(augite), plagioclase(Ab98-96), carbonate, and hyaline. Gabbro samples have wide range of plagioclase composition from anorthite to albite(Ab92-16), and other minerals like clinopyroxene(augite) and amphibole(hornblende and actinolite). Diabase samples consist of epidote group minerals and sphene with plagioclase(Ab80), pyroxene and hornblende. Dacite samples are composed of dolomite and quartz. Granite samples are composed of quartz, chlorite, and plagioclase which range from albite to oligoclase in composition (Ab98-89).

Scorpions are among the oldest terrestrial arthropods and they have passed through small morphological changes during their evolutionary history on land. They are efficient predators capable of capturing and consuming large preys and due to envenomation these animals can become a human health challenge. Understanding the physiology of scorpions can not only lead to evolutionary insights but also is a crucial step in the development of control strategies. However, the digestive process in scorpions has been scarcely studied. In this work, we describe the combinatory use of next generation sequencing, proteomic analysis and biochemical assays in order to investigate the digestive process in the yellow scorpion Tityus serrulatus, mainly focusing in the initial protein digestion. The transcriptome generated database allowed the quantitative identification by mass spectrometry of different enzymes and proteins involved in digestion. All the results suggested that cysteine cathepsins play an important role in protein digestion. Two digestive cysteine cathepsins were isolated and characterized presenting acidic characteristics (pH optima and stability), zymogen conversion to the mature form after acidic activation and a cross-class inhibition by pepstatin. A more elucidative picture of the molecular mechanism of digestion in a scorpion was proposed based on our results from Tityus serrulatus. The midgut and midgut glands (MMG) are composed by secretory and digestive cells. In fasting animals, the secretory granules are ready for the next predation event, containing enzymes needed for alkaline extra-oral digestion which will compose the digestive fluid, such as trypsins, astacins and chitinase. The digestive vacuoles are filled with an acidic proteolytic cocktail to the intracellular digestion composed by cathepsins L, B, F, D and legumain. Other proteins as lipases, carbohydrases, ctenitoxins and a chitolectin with a perithrophin domain were also detected. Evolutionarily, a large gene duplication of cathepsin L occurred in Arachnida with the sequences from ticks being completely divergent from other arachnids probably due to the particular selective pressures over this group.

Cambodian Americans experience great disparities in health compared to other Americans, yet may be underserved by conventional healthcare systems. Community-based participatory research (CBPR) is a means to engage underserved communities in health research and programming. We describe results of our efforts to engage the Cambodian grassroots members as well as formal leaders in Oakland, California. In addition to a community advisory group, we convened a Community Work Group (CWG), composed of 10 grassroots community women of varying ages and backgrounds. The project aimed to leverage the lived experiences of these women and their understandings of health and wellness in identifying specific health issues and developing culturally resonant strategies. The CWG met weekly with staff facilitators using methods for collective analysis including theater, body mapping, and other expressive arts. The approach proved logistically challenging, but resulted in novel analyses and strategies. The group identified trauma, along with poor access to education, unemployment and underemployment, social isolation, and generation gap, together with community violence, as root causes of key behavioral health issues, namely, alcohol abuse, gambling, prescription drug misuse, and domestic violence. Strategies proposed and implemented by the group and project staff were a community garden, Cambodian New Year's celebrations, and a museum exhibit on the Cambodian refugee experiences. Grassroots community engagement can support projects in identifying social determinants of health and developing the capacities of community members to conduct research and actions to improve health.

Smart Biointerface with Photoswitched Functions between Bactericidal Activity and Bacteria-Releasing Ability.

Wei, Ting; Zhan, Wenjun; Yu, Qian; Chen, Hong

2017-08-09

Smart biointerfaces with capability to regulate cell-surface interactions in response to external stimuli are of great interest for both fundamental research and practical applications. Smart surfaces with "ON/OFF" switchability for a single function such as cell attachment/detachment are well-known and useful, but the ability to switch between two different functions may be seen as the next level of "smart". In this work reported, a smart supramolecular surface capable of switching functions reversibly between bactericidal activity and bacteria-releasing ability in response to UV-visible light is developed. This platform is composed of surface-containing azobenzene (Azo) groups and a biocidal β-cyclodextrin derivative conjugated with seven quaternary ammonium salt groups (CD-QAS). The surface-immobilized Azo groups in trans form can specially incorporate CD-QAS to achieve a strongly bactericidal surface that kill more than 90% attached bacteria. On irradiation with UV light, the Azo groups switch to cis form, resulting in the dissociation of the Azo/CD-QAS inclusion complex and release of dead bacteria from the surface. After the kill-and-release cycle, the surface can be easily regenerated for reuse by irradiation with visible light and reincorporation of fresh CD-QAS. The use of supramolecular chemistry represents a promising approach to the realization of smart, multifunctional surfaces, and has the potential to be applied to diverse materials and devices in the biomedical field.

Evolution of NASA's Earth Science Digital Object Identifier Registration System

NASA Technical Reports Server (NTRS)

Wanchoo, Lalit; James, Nathan

2017-01-01

NASA's Earth Science Data and Information System (ESDIS) Project has implemented a fully automated system for assigning Digital Object Identifiers (DOIs) to Earth Science data products being managed by its network of 12 distributed active archive centers (DAACs). A key factor in the successful evolution of the DOI registration system over last 7 years has been the incorporation of community input from three focus groups under the NASA's Earth Science Data System Working Group (ESDSWG). These groups were largely composed of DOI submitters and data curators from the 12 data centers serving the user communities of various science disciplines. The suggestions from these groups were formulated into recommendations for ESDIS consideration and implementation. The ESDIS DOI registration system has evolved to be fully functional with over 5,000 publicly accessible DOIs and over 200 DOIs being held in reserve status until the information required for registration is obtained. The goal is to assign DOIs to the entire 8000+ data collections under ESDIS management via its network of discipline-oriented data centers. DOIs make it easier for researchers to discover and use earth science data and they enable users to provide valid citations for the data they use in research. Also for the researcher wishing to reproduce the results presented in science publications, the DOI can be used to locate the exact data or data products being cited.

Many studies of prehospital defibrillation have been conducted but the effects of airway intervention are unknown and neurologic follow-up has been incomplete. A non-randomized cohort prospective study was conducted to determine the effectiveness of defibrillation in prehospital cardiac arrest. Two ambulance companies in the study area developed a defibrillation protocol and they formed the experimental group. A subgroup of these patients received airway management with an esophageal obturator airway (EOA) or endotracheal intubation (ETT). The control group was composed of patients who suffered a prehospital cardiac arrest and did not receive prehospital defibrillation. All survivors were assessed for residual deficits using the Sickness Impact Profile (SIP) and the Dementia Rating Scale (DRS). A total of 221 patients were studied over a 32-month period. Both the experimental group (N = 161) and the control group (N = 60) were comparable with respect to age, sex distribution, and ambulance response time. Survival to hospital discharge was 2/60 (3.3%) in the control group and 12/161 (6.3%) in the experimental group. This difference is not statistically significant. Survival in the experimental group by airway management technique was basic airway support (3/76 3.9%), EOA (3/67 4.5%), and ETT (6/48 12.5%). The improved effect on survival by ETT management was statistically significant. Survivors had minor differences in memory, work, and recreation as compared to ischemic heart disease patients as measured by the SIP and DRS. No effect of defibrillation was found on survival to hospital discharge. However, endotracheal intubation improved survival in defibrillated patients. Survivors had a good functional outcome.

Freshwater fish evolution has been shaped by changes in the earth's surface involving changes in the courses of rivers and fluctuations in sea level. The main objective of this study is to improve our knowledge of the evolution of loricariids, a numerous and adaptive group of freshwater catfish species, and the role of geological changes in their evolution. We use a number of different phylogenetic methods to test the relationships among 52 representative taxa within the Neoplecostominae using 4676 bps of mitochondrial and nuclear DNA. Our analysis revealed that the subfamily Neoplecostominae is monophyletic, including Pseudotocinclus, with three lineages recognized. The first lineage is composed of part of Pareiorhina rudolphi, P. cf. rudolphi, and Pseudotocinclus; the second is composed of Isbrueckerichthys, Pareiorhaphis, Kronichthys, and the species Neoplecostomus ribeirensis; and the third is composed of Pareiorhina carrancas, P. cf. carrancas, Pareiorhina sp. 1, a new genus, and all the species of the genus Neoplecostomus, except N. ribeirensis. The relaxed molecular clock calibration provides a temporal framework for the evolution of the group, which we use for a likelihood-based historical biogeographic analysis to test relevant hypotheses on the formation of southeast Brazil. We hypothesize that headwater capture events and marine regressions have shaped the patterns of distribution within the subfamily Neoplecostominae throughout the distinct basins of southeast Brazil.

Imparting large macroscopic changes with small changes in polypeptide composition

NASA Astrophysics Data System (ADS)

Sing, Michelle; McKinley, Gareth; Olsen, Bradley

Block copolymers composed of polypeptides provide an excellent platform for exploring the underlying physics surrounding macroscopic associative network behavior. Previous work in our group has elucidated a difference in the mechanical properties of two nearly identical elastin-like polypeptide (ELP) endblocks. In poly(ELP)s, this substitution is known to result in tighter beta turns. These beta turns exhibit slower responses to changes in temperature within the material. Under shear, the modulus for the alanine-containing ELP triblock is almost three times higher than the glycine-containing ELP. Additionally, preliminary tensile tests show higher stress and strain at break for the alanine ELP triblock. We are able to explain the reasons for this behavior using a variety of spectroscopic and analytical techniques. Small angle neutron and x-ray scattering indicate differences in ordering between the alanine and glycine containing ELP materials both in shear and in stagnant flow.

Public urban mobility systems are composed by several transportation modes connected together. Most studies in urban mobility and planning often ignore the multi-layer nature of transportation systems considering only aggregated versions of this complex scenario. In this work we present a model for the representation of the transportation system of an entire city as a multiplex network. Using two different perspectives, one in which each line is a layer and one in which lines of the same transportation mode are grouped together, we study the interconnected structure of 9 different cities in Europe raging from small towns to mega-cities like London and Berlin highlighting their vulnerabilities and possible improvements. Finally, for the city of Zaragoza in Spain, we also consider data about service schedule and waiting times, which allow us to create a simple yet realistic model for urban mobility able to reproduce real-world facts and to test for network improvements.

Driven by advancements in technology and scientific objectives, data acquisition in observational astronomy has been changed greatly in recent years. Fully automated or even autonomous ground-based network of telescopes has now become a tendency for time-domain observational projects. The Stellar Observations Network Group (SONG) is an international collaboration with the participation and contribution of the Chinese astronomy community. The scientific goal of SONG is time-domain astrophysics such as asteroseismology and open cluster research. The SONG project aims to build a global network of 1 m telescopes equipped with high-precision and high-resolution spectrographs, and two-channel lucky-imaging cameras. It is the Chinese initiative to install a 50 cm binocular photometry telescope at each SONG node sharing the network platform and infrastructure. This work is focused on design and implementation in technology and methodology of SONG/50BiN, a typical ground-based network composed of multiple sites and a variety of instruments.

The ongoing fragmentation of medical care and mobility of patients severely restrains exchange of lifesaving information about patient's medical history in case of emergencies. Therefore, the objective of this work is to offer a secure technical solution to supply medical professionals with emergency-relevant information concerning the current patient via mobile accessibility. To achieve this goal, the official national emergency data set was extended by additional features to form a patient summary for emergencies, a software architecture was developed and data security and data protection issues were taken into account. The patient has sovereignty over his/her data and can therefore decide who has access to or can change his/her stored data, but the treating physician composes the validated dataset. Building upon the introduced concept, future activities are the development of user-interfaces for the software components of the different user groups as well as functioning prototypes for upcoming field tests.

The aim of this work is to study the radiation doses delivered to a group of patients that underwent a stereotactic breast biopsy (SBB) procedure. Mean glandular doses (MGD) were estimated from the air-kerma measured at the breast surface entrance multiplying by specific conversion coefficients (DgN) that were estimated using Monte Carlo simulations. DgN were calculated for the 0º and ±15º projections used in SBB and for the particular beam quality. Data on 61 patients were collected showing that a typical SBB procedure is composed by 10 images. MGD was on average (4 ± 2) mGy with (0.38 ± 0.06) mGy per image. The use of specific conversion coefficients instead of typical DgN for mammography/tomosynthesis yields to obtain MGD values for SBB that are around a 65% lower on average. © 2018 Institute of Physics and Engineering in Medicine.

1990-01-01

This work is a study of the personality of the wives of alcoholic patients composed by means of a structures interview, the MMPI personality questionnaire and the Instrument I used to evaluate aggressivity. Among the discoveries made, we must emphasize that 20% of the wives knew of their partner's excessive alcohol consumption before marriage, while married, 75% were victims of some kind of violent incident, 43% had personal psychopathological backgrounds, 15% were "repeaters wives" "those who had alcoholic parents). In the MMPI test, these women represent a significantly high profile, in which the scales Hs, D and Hy are the highest, amongst which their most outstanding personality traits include passivity, dependency and insecurity. Furthermore, those wives whose husbands have had relapses, represent a higher Pd scale than the other group. The Instrument I used to evaluate aggressivity also emphasizes this passive-aggressive tendency in the wives.

For blood-contacting biomedical implants like retrievable vena cava filters, surface-based diagnostic devices or in vivo sensors, limiting thrombosis and cell adhesion is paramount, due to a decrease even failure in performance. Plasma deposited PEO-like films were investigated as surface modifications. In this work, mixed gas composed of tetraethylene glycol dimethyl ether (tetraglyme) vapor and oxygen was used as precursor. It was revealed that plasma polymerization under high ratio of oxygen/tetraglyme led to deposition of the films that had high content of ether groups. This kind of PEO-like films had good stability in phosphate buffer solution. In vitro hemocompatibility and endothelial cell (EC) adhesion revealed low platelet adhesion, platelet activation, fibrinogen adhesion, EC adhesion and proliferation on such plasma deposited PEO-like films. This made it a potential candidate for the applications in anti-fouling surfaces of blood-contacting biomedical devices.

Writing more informative letters of reference.

Writing a meaningful and valuable letter of reference is not an easy task. Several factors influence the quality of any letter of reference. First, the accuracy and reliability of the writer's impressions and judgment depend on how well he knows the individual being described. Second, the writer's frame of reference, which is determined by the number of persons at the same level that he has worked with, will impact the context and significance of his beliefs and estimations. Third, the letter-writing skills of the person composing the letter will naturally affect the letter. To support the other components of a candidate's application, a letter of reference should provide specific examples of how an individual's behavior or attitude compares to a reference group and should assess "intangibles" that are hard to glean from a curriculum vitae or from test scores. This report offers suggestions that should help physicians write more informative letters of reference.

2017-01-01

The primary standard for X-ray photons is based on parallel-plate free-air ionization chamber (FAC). Therefore, the Atomic Energy Organization of Iran (AEOI) is tried to design and build the free-air ionization chamber, FAC-IR-300, for low and medium energy X-ray dosimetry. The main aim of the present work is to investigate specification of the FAC-IR-300 ionization chamber and design it. FAC-IR-300 dosimeter is composed of two parallel plates, a high voltage (HV) plate and a collector plate, along with a guard electrode that surrounds the collector plate. The guard plate and the collector were separated by an air gap. For obtaining uniformity in the electric field distribution, a group of guard strips was used around the ionization chamber. These characterizations involve determining the exact dimensions of the ionization chamber by using Monte Carlo simulation and introducing correction factors.

To investigate the effectiveness of pulmonary rehabilitation (PR) in exercise capacity and quality of life in patients with chronic obstructive pulmonary disease (COPD) with and without global fat-free mass (FFM) depletion. Retrospective case-control. Outpatient clinic, university center. COPD patients (N=102) that completed PR were initially evaluated. PR including whole-body and weight training for 12 weeks, 3 times per week. St. George Respiratory Questionnaire (SGRQ), 6-minute walk distance (6MWD), and FFM evaluation applied before and after PR. Patients were stratified according to their FFM status measured by bioelectric impedance. They were considered depleted if the FFM index was ≤ 15 kg/m(2) in women and ≤ 16 kg/m(2) in men. From the initial sample, all depleted patients (n=31) composed the FFM depleted group. It was composed predominantly by women (68%) with a mean age ± SD of 64.4 ± 7.3 years and a forced expiratory volume in 1 second of 33.6%=-13.2% predicted. Paired for sex and age, 31 nondepleted patients were selected from the initial sample to compose the nondepleted group. Improvement in the 6MWD was similar in these 2 groups after PR. Both groups improved SGRQ scores, although the observed power was small and did not allow adequate comparison between depleted and nondepleted patients. There was no difference between groups in weight change, whereas FFM tended to be greater in depleted patients. This increase had no correlation with the 6MWD or the SGRQ. Benefits of PR to exercise capacity were similar comparing FFM depleted and nondepleted COPD patients. Although FFM change tended to be greater in depleted patients, this increase had no definite relation with clinical outcomes. Copyright © 2013 American Congress of Rehabilitation Medicine.

The aim of this study was to describe and understand the relationship of swimmers' practice intensity and alexithymia features in discourse. This study investigated psychological processes in two groups of male swimmers training at different intensities. The first group was composed of 10 Expert amateurs (M age = 19.5 yr., SD = 1.9), who were competing at the national or international level and trained 22 hours per week. The second group was composed of 10 Amateur swimmers (M age = 20.5 yr., SD = 1.4), who competed at the regional level and trained 6 hours per week. The discourse of swimmers was analysed using the ALCESTE (Analyse de Lexèmes Coocurents dans les Enoncés Simples d'un Texte) method of discourse analysis. Discourse analysis was performed on speech samples produced by swimmers. All the swimmers showed alexithymic verbal behaviour as regards both the means of expression used and the feelings and emotions expressed. This lack of articulateness was more pronounced in the Expert than in the Amateur group. The difference of alexithymic features in correlation with the intensity of sport practice raises the question of the health benefits of intense sports practice and the need for psychological assessment of athletes.

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.

Waulsortian-type buildups in the lower carboniferous of the Bechar basin, northwestern Sahara of Algeria, North Africa

The carboniferous strata in the Bechar basin can be subdivided into three major groups. The lower group is composed of bioclastic and perireefal carbonates. The middle group is exemplified by carbonate platform deposits that were eroded during episodes of emergence by channels of continental derived sediments. The upper group is represented by terrigenous deposits composed mainly of deltaic, fluvial, and lacustrine deposits, with the sporadic presence of coal seams. The carboniferous Waulsortian-type buildups within the Bechar basin occur in the lower group. They are exposed above the desert floor along a south to north-northwest-trending axis, with the younger buildups locatedmore » to the south and the older ones to the north. These bioherms are apparently younger than those recognized in Europe and North America. These Algerian bioherms were initiated and persisted during the time interval represented by the conodont gnathodus bilineatus zone (lower Visean-upper Visean boundary). Although they are younger than their European and North American counterparts that are of Tournaisian-lower Visean age, these mounds appear to have formed in similar environmental and tectono-sedimentary conditions. Their areal extent, geometry, and facies relationships suggest that they were limited to a shelf edge. Their deposition environments range from shallow marine to deep sea.« less

Effects of group songwriting on motivation and readiness for treatment on patients in detoxification: a randomized wait-list effectiveness study.

Silverman, Michael J

2012-01-01

Songwriting is a commonly utilized music therapy technique for clients in substance abuse rehabilitation. For these patients, motivation and readiness for treatment remain two key treatment areas. Moreover, there is a lack of randomized and controlled music therapy studies systematically investigating how group songwrit-ing can affect patients on a detoxification unit. The purposes of this study were to measure the effects of a single group songwriting session on motivation and readiness for treatment and determine emerging themes from patient-composed songs with patients on a detoxification unit. Participants (N = 99) were randomized to experimental (posttest only) or wait-list control (pretest only) conditions to provide treatment to all participants in an inclusive single-session design. There were significant between-group differences in motivation and readiness for treatment, with experimental participants having higher means than control participants. Code categorizations from patients' composed song lyrics concerned "action," "emotions and feelings," "change," "reflection," "admission," and "responsibility." From the results of this study, it seems that a single group songwriting session can be an effective intervention concerning motivation and readiness for treatment in patients on a detoxification unit. Implications for clinical practice, suggestions for future research, and limitations are provided.

Little is known regarding young and future dentists' career choices, professional identity, and working conditions in Germany. While the dental healthcare environment and demands in treatment are changing, it remains unclear what job perceptions young dentists have developed at the beginning of their work life and if and how these perceptions change during the subsequent years. The aim of this study was to survey future and young dentists regarding their professional identity, planned career paths, and working conditions and strains to understand career decisions and choices and enable policy makers to include future dentists' views and expectations in their decisions. This study is a longitudinal nationwide survey over a time span of 4 years of dental students and young dentists in Germany and is comprised of three waves. The first wave focuses on dental students in their final year before the state examination and is composed of a qualitative pre-study in the form of focus groups and a quantitative main survey in the form of a questionnaire. The end points were established to analyse (1) the professional identity of the young future dentists; (2) their career paths, preparation for a career, and basic career conditions; and (3) perceived conditions and strains. The aim of the overall survey was to depict the development of these three aspects during the first years of work life. All of the questions were evaluated with a descriptive univariate analysis. The analysed subgroups were grouped according to gender, target working condition (employed/self-employed), and primary socialisation (parents dentists/parents not dentists). To our knowledge, this is the only study which focuses on career choices, professional identity, and working conditions of future and young dentists in Germany. The longitudinal observation provides information that is essential for professional and purposive dental health care planning, and to meet the oral health demands and needs of the German population appropriately over the long term.

In our Quebec (Canada) University Hospital Center, 68 medication carts have been implemented as part of a nationally funded project on drug distribution technologies. There are limited data published about the impact of medication carts in point-of-care units. Our main objective was to assess nursing staff's perception and satisfaction of medication carts on patient safety and ergonomics. Quantitative and qualitative cross-sectional study. Data were gathered from a printed questionnaire administered to nurses and an organized focus group composed of nurses and pharmacists. A total of 195 nurses completed the questionnaire. Eighty percent of the nurses agreed that medication carts made health care staff's work easier and 64% agreed that it helped to reduce medication incidents/accidents. Only 27% and 43% agreed that carts' location reduces the risk of patients' interruptions and colleagues' interruptions, respectively. A total of 17 suggestions were extracted from the focus group (n = 7 nurses; n = 3 pharmacist) and will be implemented in the next year. This descriptive study confirms the positive perception and satisfaction of nurses exposed to medication carts. However, interruptions are a major concern and source of dissatisfaction. The focus group has revealed many issues which will be improved.

FTIR Analysis of Functional Groups in Aerosol Particles

Secondary organic aerosols (SOA) are suspensions of particulate matter composed of compounds formed from chemical reactions of organic species in the atmosphere. Atmospheric particulate matter can have impacts on climate, the environment and human health. Standardized techniques to analyze the characteristics and composition of complex secondary organic aerosols are necessary to further investigate the formation of SOA and provide a better understanding of the reaction pathways of organic species in the atmosphere. While Aerosol Mass Spectrometry (AMS) can provide detailed information about the elemental composition of a sample, it reveals little about the chemical moieties which make up the particles. This work probes aerosol particles deposited on Teflon filters using FTIR, based on the protocols of Russell, et al. (Journal of Geophysical Research - Atmospheres, 114, 2009) and the spectral fitting algorithm of Takahama, et al (submitted, 2012). To validate the necessary calibration curves for the analysis of complex samples, primary aerosols of key compounds (e.g., citric acid, ammonium sulfate, sodium benzoate) were generated, and the accumulated masses of the aerosol samples were related to their IR absorption intensity. These validated calibration curves were then used to classify and quantify functional groups in SOA samples generated in chamber studies by MIT's Kroll group. The fitting algorithm currently quantifies the following functionalities: alcohols, alkanes, alkenes, amines, aromatics, carbonyls and carboxylic acids.

In 2007, the Health Councillorship of the Piedmont region announced, in convention with the Psychology Department of the University of Turin, of the creation of "Workgroup for Safeguard of Organizational Wellbeing" composed by psychologists, occupational doctors, and superintendents for Prevention and Protection services. This group is aimed at promoting pilot experiences in the Health Units in order to prevent and combat psychosocial discomfort and to sustain workers' wellbeing. A complex intervention started in January 2009 and involved the personnel from Services for the Organization and Development of Human Resources, Personnel Services, Services for Occupational Medicine, Services of Communication, Quality Services, belonging to all of the Health Units from Piedmont, and of some structures operating within the national health service, for a total of 23 work groups. Based on the results produced and/or from the shared reflections in the classroom between the 23 groups, four main themes were singled out, corresponding to different levels and fields of interventions, in order to favour the contrast of psychosocial distress and to promote a culture of wellbeing, were adopted taking into account needs and cultural specificity of different Units' realities. The activities embarked on, inside every main theme represent, in the expectations of all the participants, good practices that could be spread to the different Local Health Units.

Research in hospital settings faces several difficulties. Information technologies and certain Web 2.0 tools may provide new models to tackle these problems, allowing for a collaborative approach and bridging the gap between clinical practice, teaching and research. We aim to gather a community of researchers involved in the development of a network of learning and investigation resources in a hospital setting. A multi-disciplinary work group analysed the needs of the research community. We studied the opportunities provided by Web 2.0 tools and finally we defined the spaces that would be developed, describing their elements, members and different access levels. WIKINVESTIGACION is a collaborative web space with the aim of integrating the management of all the hospital's teaching and research resources. It is composed of five spaces, with different access privileges. The spaces are: Research Group Space 'wiki for each individual research group', Learning Resources Centre devoted to the Library, News Space, Forum and Repositories. The Internet, and most notably the Web 2.0 movement, is introducing some overwhelming changes in our society. Research and teaching in the hospital setting will join this current and take advantage of these tools to socialise and improve knowledge management.

Inflammatory biomarkers provide a minimally invasive means for early detection and specific treatment of metabolic syndrome and related disorders. The objective of this work was to search for inflammatory biomarkers of cardiometabolic risk in obese type 2 diabetics. The study was performed on 165 persons attending the medical outpatient clinic of Ismailia General Hospital. Their mean age was (50.69 ± 10.15) years. They were divided into three groups. The control group was composed of 55 non-obese, non-diabetic healthy volunteers, 32 males and 23 females. Two study groups were included in this study: group 2 was composed of 55 obese, non-diabetic subjects, 25 males and 30 females matched for age and gender. All patients including the control were subjected to clinical history taking, a clinical examination for the measurement of body mass index (BMI). Investigations were carried out for fasting blood glucose, fasting serum insulin, insulin resistance (IR), the lipid profile, lipoprotein band lipoprotein phospholipase A2, and non-high-density lipoprotein cholesterol (non-HDL-C). Urea, albumin and creatinine analysis and liver function tests were performed, and a complete blood count (CBC) was taken. Hemoglobin A1C (HbA1C), serum high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were tested. There were statistically significant differences among the studied groups in terms of total cholesterol, non-HDL-C, high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), lipoprotein-associated phospholipase A2 and apolipoprotein B. The inflammatory biomarkers hs-CRP, IL-6 and TNF-α were significantly statistically increased in the study groups by (1.62 ± 0.99, 2.32 ± 1.11), (1.73 ± 1.14, 2.53 ± 1.34), and (1.87 ± 1.09, 2.17 ± 0.89) respectively, where p < 0.01. Significant positive correlation was found between Homeostatic Model Assessment (HOMA)-IR, hs-CRP and IL-6. There was a significant positive correlation between non-HDL and hs-CRP, IL-6 and TNF-α and triglycerides and hs-CRP. In conclusion, in this study, CRP, IL-6, and TNF-α were significantly elevated in obese Egyptian type 2 diabetics and were positively correlated with insulin resistance, non-HDL and triglycerides. These inflammatory biomarkers could help in the premature identification of obese type 2 diabetic patients at high cardiometabolic risk. Additionally, these biomarkers are critical for providing prognostics and the validity of future potential anti-inflammatory therapeutic modalities. PMID:29099041

Are clownfish groups composed of close relatives? An analysis of microsatellite DNA variation in Amphiprion percula.

Buston, Peter M; Bogdanowicz, Steven M; Wong, Alex; Harrison, Richard G

2007-09-01

A central question of evolutionary ecology is: why do animals live in groups? Answering this question requires that the costs and benefits of group living are measured from the perspective of each individual in the group. This, in turn, requires that the group's genetic structure is elucidated, because genetic relatedness can modulate the individuals' costs and benefits. The clown anemonefish, Amphiprion percula, lives in groups composed of a breeding pair and zero to four nonbreeders. Both breeders and nonbreeders stand to gain by associating with relatives: breeders might prefer to tolerate nonbreeders that are relatives because there is little chance that relatives will survive to breed elsewhere; nonbreeders might prefer to associate with breeders that are relatives because of the potential to accrue indirect genetic benefits by enhancing anemone and, consequently, breeder fitness. Given the potential benefits of associating with relatives, we use microsatellite loci to investigate whether or not individuals within groups of A. percula are related. We develop seven polymorphic microsatellite loci, with a number of alleles (range 2-24) and an observed level of heterozygosity (mean = 0.5936) sufficient to assess fine-scale genetic structure. The mean coefficient of relatedness among group members is 0.00 +/- 0.10 (n = 9 groups), and there are no surprising patterns in the distribution of pairwise relatedness. We conclude that A. percula live in groups of unrelated individuals. This study lays the foundation for further investigations of behavioural, population and community ecology of anemonefishes which are emerging as model systems for evolutionary ecology in the marine environment.

Adaptive neuro-heuristic hybrid model for fruit peel defects detection.

Woźniak, Marcin; Połap, Dawid

2018-02-01

Fusion of machine learning methods benefits in decision support systems. A composition of approaches gives a possibility to use the most efficient features composed into one solution. In this article we would like to present an approach to the development of adaptive method based on fusion of proposed novel neural architecture and heuristic search into one co-working solution. We propose a developed neural network architecture that adapts to processed input co-working with heuristic method used to precisely detect areas of interest. Input images are first decomposed into segments. This is to make processing easier, since in smaller images (decomposed segments) developed Adaptive Artificial Neural Network (AANN) processes less information what makes numerical calculations more precise. For each segment a descriptor vector is composed to be presented to the proposed AANN architecture. Evaluation is run adaptively, where the developed AANN adapts to inputs and their features by composed architecture. After evaluation, selected segments are forwarded to heuristic search, which detects areas of interest. As a result the system returns the image with pixels located over peel damages. Presented experimental research results on the developed solution are discussed and compared with other commonly used methods to validate the efficacy and the impact of the proposed fusion in the system structure and training process on classification results.

Quantum refrigerators and the third law of thermodynamics.

PubMed

Levy, Amikam; Alicki, Robert; Kosloff, Ronnie

2012-06-01

The rate of temperature decrease of a cooled quantum bath is studied as its temperature is reduced to absolute zero. The third law of thermodynamics is then quantified dynamically by evaluating the characteristic exponent ζ of the cooling process dT(t)/dt∼-T^{ζ} when approaching absolute zero, T→0. A continuous model of a quantum refrigerator is employed consisting of a working medium composed either by two coupled harmonic oscillators or two coupled two-level systems. The refrigerator is a nonlinear device merging three currents from three heat baths: a cold bath to be cooled, a hot bath as an entropy sink, and a driving bath which is the source of cooling power. A heat-driven refrigerator (absorption refrigerator) is compared to a power-driven refrigerator. When optimized, both cases lead to the same exponent ζ, showing a lack of dependence on the form of the working medium and the characteristics of the drivers. The characteristic exponent is therefore determined by the properties of the cold reservoir and its interaction with the system. Two generic heat bath models are considered: a bath composed of harmonic oscillators and a bath composed of ideal Bose/Fermi gas. The restrictions on the interaction Hamiltonian imposed by the third law are discussed. In the Appendices, the theory of periodically driven open systems and its implication for thermodynamics are outlined.

Challenges in the estimation of Net SURvival: The CENSUR working survival group.

PubMed

Giorgi, R

2016-10-01

Net survival, the survival probability that would be observed, in a hypothetical world, where the cancer of interest would be the only possible cause of death, is a key indicator in population-based cancer studies. Accounting for mortality due to other causes, it allows cross-country comparisons or trends analysis and provides a useful indicator for public health decision-making. The objective of this study was to show how the creation and formalization of a network comprising established research teams, which already had substantial and complementary experience in both cancer survival analysis and methodological development, make it possible to meet challenges and thus provide more adequate tools, to improve the quality and the comparability of cancer survival data, and to promote methodological transfers in areas of emerging interest. The Challenges in the Estimation of Net SURvival (CENSUR) working survival group is composed of international researchers highly skilled in biostatistics, methodology, and epidemiology, from different research organizations in France, the United Kingdom, Italy, Slovenia, and Canada, and involved in French (FRANCIM) and European (EUROCARE) cancer registry networks. The expected advantages are an interdisciplinary, international, synergistic network capable of addressing problems in public health, for decision-makers at different levels; tools for those in charge of net survival analyses; a common methodology that makes unbiased cross-national comparisons of cancer survival feasible; transfer of methods for net survival estimations to other specific applications (clinical research, occupational epidemiology); and dissemination of results during an international training course. The formalization of the international CENSUR working survival group was motivated by a need felt by scientists conducting population-based cancer research to discuss, develop, and monitor implementation of a common methodology to analyze net survival in order to provide useful information for cancer control and cancer policy. A "team science" approach is necessary to address new challenges concerning the estimation of net survival. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

To compare baseline characteristics, treatment frequency, visual acuity (VA), and morphologic outcomes of eyes with >50% of the lesion composed of blood (B50 group) versus all other eyes (Other group) enrolled in the Comparison of Age-Related Macular Degeneration Treatments Trials (CATT). Prospective cohort study within a multicenter randomized clinical trial. CATT patients with neovascular age-related macular degeneration (AMD). Treatment for the study eye was assigned randomly to either ranibizumab or bevacizumab and to 3 different dosing regimens over a 2-year period. Reading center graders evaluated baseline and follow-up morphology in color fundus photographs, fluorescein angiography (FA), and optical coherence tomography (OCT). Masked examiners tested VA. Morphologic features and VA at 1 and 2 years. The B50 group consisted of 84 of 1185 (7.1%) patients enrolled in CATT. Baseline lesion characteristics differed between groups. In the B50 group, choroidal neovascularization size was smaller (0.73 vs 1.83 disc areas [DA]; P < 0.001), total lesion size was greater (4.55 vs 2.31 DA; P <0.001), total retinal thickness was greater (524 vs 455 μm; P = 0.02), and mean VA was worse (56.0 vs 60.9 letters; P = 0.002). Increases in mean VA were similar in the B50 and Other groups at 1 year (+9.3 vs +7.2 letters; P = 0.22) and at 2 years (9.0 vs 6.1 letters; P = 0.17). Eyes treated PRN received a similar number of injections in the 2 groups (12.2 vs 13.4; P = 0.27). Mean lesion size in the B50 group decreased by 1.2 DA at both 1 and 2 years (primarily owing to resolution of hemorrhage) and increased in the Other group by 0.33 DA at 1 year and 0.91 DA at 2 years (P < 0.001). Leakage on FA and fluid on OCT were similar between groups at 1 and 2 years. In CATT, the B50 group had a visual prognosis similar to the Other group. Lesion size decreased markedly through 2 years. Eyes like those enrolled in CATT with neovascular AMD lesions composed of >50% blood can be managed similarly to those with less or no blood. Copyright © 2015 American Academy of Ophthalmology.

Mandrills (Mandrillus sphinx) are enigmatic Old World primates whose social organization and ecology remain poorly known. Previous studies indicated, for example, that groups are composed of only adult females and their young or that several units composed of one adult male and several females make up larger permanent social units. Here, we present the first data on group composition and male ranging patterns from the only habituated wild mandrill group and examine how home range size and daily path length varied with environmental and demographic factors over a 15-month period. Our study site is located in southern Gabon where we followed the group on a daily basis, collecting data on presence, ranging, behavior, and parasite load of its individual members. Throughout the study, the group was made up of about 120 individuals, including several non-natal and natal adult and sub-adult males. One-male units were never observed. The mandrills traveled an estimated 0.44-6.50 km/day in a home range area of 866.7 ha. Exploratory analyses revealed that precipitation, the number of adult males present, and the richness of protozoan parasites were all positively correlated with daily path length. These results clarify the social system of mandrills and provide first insights into the factors that shape their ranging patterns. © 2015 Wiley Periodicals, Inc.

Ground-water levels in aquifers used for residential supply, Campton Township, Kane County, Illinois

Kay, Robert T.; Kraske, Kurt A.

1996-01-01

The U.S. Geological Survey, in cooperation with the Campton Township Board of Trustees, measured water levels in the aquifers used for residential supply in Campton Township, Kane County, Illinois. Aquifers used for residential supply are the shallow and deep aquifers in the glacial drift, composed of unconsolidated sand and gravels; the Alexandrian-Maquoketa aquifer, composed of dolomite and shale of the Alexandrian Series and the Maquoketa Group; the Galena-Platteville aquifer, composed of dolomite of the Platteville and Galena Groups; and the Ancell aquifer, composed of sandstones of the Glenwood Formation and the St. Peter Sanstone. Water-level altitudes in the shallow drift aquifers generally follow surface topography. Analysis of water-level data does not clearly indicate overutilization of these aquifers. Water-level altitudes in the deep drift aquifers decrease from west to east. Comparison of historical depth to water measurements with current (1995) measurements indicates large decreases in water levels in some areas. The deep drift aquifers may be overutilized at these locations. Water-level altitudes in the Alexandrian-Maquoketa aquifer generally decrease from west to east. The potentiometric surface of the aquifer follows the bedrock-surface topography in some locations. Localized low water-level altitudes and large decreases in water levels indicate the Alexandrian-Maquoketa aquifer is overutilized in several areas. Water-level altitudes in the wells finished in the Galena- Platteville aquifer vary by more than 300 feet. Large decreases in water levels in wells finished in the Galena-Platteville aquifer indicate the Galena-Platteville and Alexandrian-Maquoketa aquifers are overutilized in the northern part of the township. Water-level altitudes in the wells finished in the Ancell aquifer are also highly variable. There is no indication that the Ancell aquifer is overutilized.

Geochemistry of Martian Meteorites and the Petrologic Evolution of Mars

Mafic igneous rocks serve as probes of the interiors of their parent bodies - the compositions of the magmas contain an imprint of the source region composition and mineralogy, the melting and crystallization processes, and mixing and assimilation. Although complicated by their multifarious history, it is possible to constrain the petrologic evolution of an igneous province through compositional study of the rocks. Incompatible trace elements provide one means of doing this. I will use incompatible element ratios of martian meteorites to constrain the early petrologic evolution of Mars. Incompatible elements are strongly partitioned into the melt phase during igneous processes. The degree of incompatibility will differ depending on the mineral phases in equilibrium with the melt. Most martian meteorites contain some cumulus grains, but nevertheless, incompatible element ratios of bulk meteorites will be close to those of their parent magmas. ALH 84001 is an exception, and it will not be discussed. The martian meteorites will be considered in two groups; a 1.3 Ga group composed of the clinopyroxenites and dunite, and a younger group composed of all others.

There is an essential need for searching for the new compounds effective in the treatment of infections caused by multidrug-resistant bacteria. This paper is the third part of a series associated with the exploration of new antibacterial agents and it discusses the compounds belonging to the group of quinolones and substances possessing a hybrid structure composed of the quinolone molecule and other compounds. Eleven new substances at the stage of clinical trials are presented. Three of them belong to the group of non-fluorinated quinolone (nemonoxacin, ozenoxacin and KRP-AM 1977X), while six are the quinolones containing fluorine atom at 6 position of the carbon atom in the quinoline ring (zabofloxacin, finafloxacin, delafloxacin, JNJ-Q2, WCK771 and KPI-10). The remaining two compounds possess a hybrid construction composed of the quinolone structure and other molecules (cadazolid and CBR-2092). There is a chance in the near future, that the presented compounds can extend the range of existing antibacterial drugs and provide an alternative to currently available medicinal products.

Dynamics and structure of hydrogen-bonding glass formers: Comparison between hexanetriol and sugar alcohols based on dielectric relaxation

2010-04-01

Broadband dielectric spectra of supercooled 1,2,6-hexanetriol are presented in order to reveal physical picture behind a glass transition of polyhydric alcohols. It has been reported so far that temperature dependences of α relaxation time for sugar alcohols exhibit systematic trend against number of carbon atoms or OH groups per molecule. However, because each molecule is composed of equal number of carbon atoms and OH groups in the case of the reported sugar alcohols, the more dominant parameter to govern the α relaxation dynamics has not been discussed. By using a chemical structure of the hexanetriol composed of the deferent number of carbon and OH, it is possible to determine the dominant parameter. From temperature dependence of α relaxation times, it is strongly supported that the number of OH groups is the dominant parameter. Furthermore, from an analysis of static dielectric constant, it is suggested that local hydrogen-bonding structure is similar among all polyhydric alcohols. From these two results, a simple picture of the origin of the systematic character is proposed.

OBJECTIVE: To compare radial shockwave treatment and conventional physiotherapy for plantar fasciitis. MATERIALS AND METHODS: Thirty-two patients with plantar fasciitis were included in this study. They were randomly divided into two groups. Group 1 was composed of 16 patients who underwent 10 physiotherapy sessions each, consisting of ultrasound, kinesiotherapy and instruction for stretching exercises at home. Group 2 was composed of 16 patients who underwent three applications of radial shockwaves (once a week) and received instruction for stretching exercises at home. Pain and ability to function were evaluated before treatment, immediately afterwards, and three months later. The mean age of the patients was 47.3 ± 10.3 years (range 25–68); 81% were female, 87% were overweight, 56% had bilateral impairment, and 75% used analgesics regularly. RESULTS: Both treatments were effective for pain reduction and for improving the functional abilities of patients with plantar fasciitis. The effect of the shockwaves was apparent sooner than physiotherapy after the onset of treatment. CONCLUSION: Shockwave treatment was no more effective than conventional physiotherapy treatment when evaluated three months after the end of treatment. PMID:19219314

Premature birth suggests condition of biological vulnerability, predisposing to neurological injuries, requiring hospitalization in Neonatal Intensive Care Units, which, while contributing to increase the survival rates, expose infants to sensory stimuli harmful to the immature organism. To evaluate the sensory processing at 4 and 6months' corrected age. This was a descriptive cross-sectional study with a sample of 30 infants divided into an experimental group composed of preterm infants (n=15), and a control group composed of full-term infants (n=15). The infants were assessed using the Test of Sensory Functions in Infants. The preterm infants showed poor performance in the total score of the test in reactivity to tactile deep pressure and reactivity to vestibular stimulation. When groups were compared, significant differences in the total score (p=0.0113) and in the reactivity to tactile deep pressure (p<0.0001) were found. At 4 and 6months of corrected age, the preterm infants showed alterations in sensory processing. These changes were most evident in reactivity to tactile deep pressure and vestibular stimulation.

The surfacing of past assessment strategies within interdisciplinary teams when encountering an open-ended assignment in an undergraduate sustainability course

267 undergraduate students in an interdisciplinary environmental sustainability course were divided into 66 groups for the duration of the semester. The formation of the groups proceeded by first assigning all of the science majors to groups in a random order. This was followed by assigning the engineering majors, the liberal arts majors, and finally the business majors in turn. After all of the students had been assigned to a group, every group had at least one engineering student and one science student. 11 groups had a liberal arts student but no business student. 26 groups had a business student but no liberal arts student. 29 groups were composed of students from all four majors. During the semester, the groups created an environmental action plan to address one of Singapore's major sustainability concerns: food. In service of the course's emphasis on interdisciplinary communication, the groups were required to create a video to support their environmental action plan. The evaluation method for the videos built on our prior work with rubrics (Hartman & Goodkin, 2016). While we provided a number of examples of videos communicating environmental action plans, students were not prescribed a particular format for their video. To the consternation of some students, the instructor deliberately left the video assessment open-ended. After the semester ended, a researcher coded all 66 videos for the food sustainability issues they identified, their proposed solutions, and their video approach. Approaches included animations, virtual handwriting/drawing, role-playing, PowerPoint presentations, and picture slideshows. Given the open-ended nature of the video project, we hypothesized that groups would converge on approaches that at least one team member was familiar with. We knew from prior work with the business school, that its students engage in role-play activities fairly frequently. Teams with a business major and without a liberal arts major adopted the role-play approach 23% of the time. Teams with both, exhibited the role-play approach 10% of the time. Teams without a business major did not exhibit the role-play approach. The differences in approach rates support the notion that students carry their repertoire of assessment practices with them to courses outside of their domain.

Purpose: To evaluate the reliability of RPN (Risk Priority Number) decided by expert group and to provide preliminary data for adapting FMEA in Korea. Methods: 1163 Incidents reported in ROSIS for 11 years were used as a real data to be compared with, and were categorized into 146 items. The questionnaire was composed of the 146 items and respondents had to valuate ‘occurrence (O)’, ‘severity (S)’, ‘detectability (D)’ of each item on a scale from 1 to 10 according to the proposed AAPM TG-100 rating scales. 19 medical physicists from 19 different organizations in Korea had participated in the survey.more » Because the number of ROSIS items was not evenly spread enough to be classified into 10 grades, 1–5 scale was chosen instead of 1–10 and survey result was also fit to 5 grades to compare. Results: The average O,S,D were 1.77, 3.50, 2.13, respectively and the item which had the highest RPN(32) was ‘patient movement during treatment’ in the survey. When comparing items ranked in the top 10 of each survey(O) and ROSIS database, two items were duplicated and ‘Simulation’ and ’Treatment’ were the most frequently ranked RT process in top 10 of survey and ROSIS each. The Chronbach α of each RT process were ranged from 0.74 to 0.99 and p-value was <0.001. When comparing O*D, the average difference was 1.4. Conclusion: This work indicates the deviation between actual risk and expectation. Considering that the respondents were Korean and ROSIS is mainly composed of incidents happened in European countries and some of the top 10 items of ROSIS cannot be applied in radiotherapy procedure in Korea, the deviation could have been came from procedural difference. Moreover, if expert group was consisted of experts from various parts, expectation might have been more accurate. Therefore, further research on radiotherapy risk estimation is needed.« less

[Purpose] This study was carried out to examine the effect of the application of group exercise program composed to induce interests and assertive participation of adults with cerebral palsy on the self-efficacy and activities of daily living, as well as to provide basic clinical data that are effective and trustworthy in enhancing the physical and emotional interaction in the future. [Subjects and Methods] Those among the 23 adult with cerebral palsy who are the subjects of research and able to participate only in the evaluation of measurement tools prior to and after the experiment were allocated to the control group while only those who can participate in the group exercise program implemented over 12 sessions were allocated to the experimental group. For the control group, a range of motion of joint exercise and stretching exercise were executed on the arms, legs and trunk, while for the experimental group, group exercise that is implemented with participation of several subjects simultaneously was executed 2 times a week with 40 minutes for each session over a period of 6 weeks for the total of 12 sessions. [Results] In both the experimental group and the control group, there were statistically significant changes in the average scores of self-efficacy and activities of daily living after the exercise in comparison to that prior to the exercise. Moreover, there were statistically significant differences in self-efficacy and activities of daily living in terms of quantity of change prior to and after the exercise between the two groups. [Conclusion] Therefore, group exercise program composed to induce physical and emotional interaction, and active participation of adults with cerebral palsy can be considered as an effective intervention method in improving their self-efficacy and activities of daily living.
