    There are no published studies on physical dating violence in college students in Chile, and campuses across the country currently lack systematized programs to prevent or respond to this public health problem. This is the first study to examine prevalence and predictors of physical dating violence victimization with a sample of female college students in Chile. A closed-ended questionnaire was administered to students enrolled in general education courses at a major public university. The prevalence of women's physical dating violence victimization was calculated, and generalized ordered logit models were used to estimate risk factors for such victimization (n = 441). Ancillary analyses examined associations of dating violence victimization with experiences of unwanted sexual contact and forced condom nonuse. Approximately 21% of subjects reported one or more incidents of physical dating violence not involving physical injury since age 14, and another 5% reported at least one incident resulting in physical injury during this time period. Risk factors identified in five sequential models were sexual abuse and witnessing of domestic violence in childhood, low parental education, residence away from the parental home, urban residence, and having had sexual intercourse. Maternal employment and religious participation had protective effects. Dating violence victimization was found to be significantly associated with experiences of unwanted sexual contact and forced condom nonuse. The study findings show a high prevalence of physical dating violence, strong associations between several sociodemographic factors and dating violence, and links between dating violence and sexual/reproductive risk. Our results indicate a need to expand attention to this public health problem in Chile as well as other developing countries, where research and prevention/response initiatives have generally been similarly limited. The findings also have important implications for the content of

    Introduction Theoretic models suggest that associations between substance use and dating violence perpetration may vary in different social contexts, but few studies have examined this proposition. The current study examined whether social control and violence in the neighborhood, peer, and family contexts moderate the associations between substance use (heavy alcohol use, marijuana, and hard drug use) and adolescent physical dating violence perpetration. Methods Adolescents in the eighth, ninth, and tenth grades completed questionnaires in 2004 and again four more times until 2007 when they were in the tenth, 11th and 12th grades. Multilevel analysis was used to examine interactions between each substance and measures of neighborhood, peer, and family social control and violence as within-person (time-varying) predictors of physical dating violence perpetration across eighth through 12th grade (N=2,455). Analyses were conducted in 2014. Results Physical dating violence perpetration increased at time points when heavy alcohol and hard drug use were elevated; these associations were weaker when neighborhood social control was higher and stronger when family violence was higher. Also, the association between heavy alcohol use and physical dating violence perpetration was weaker when teens had more-prosocial peer networks and stronger when teens’ peers reported more physical dating violence. Conclusions Linkages between substance use and physical dating violence perpetration depend on substance use type and levels of contextual violence and social control. Prevention programs that address substance use–related dating violence should consider the role of social contextual variables that may condition risk by influencing adolescents’ aggression propensity.

    Physical activity has emerged as a distinct area of public health practice. As this field evolved, the need for a professional organization for physical activity practitioners in public health became evident. A collaboration of several existing public health professional organizations formed to address this new area of public health practice. The collaboration laid the foundation to establish a professional organization. National Association of Physical Activity Practitioners in Public Health (NSPAPPH) was launched in April 2006. NSPAPPH accomplishments to date include convening a national meeting of physical activity practitioners, conducting strategic planning, adopting bylaws and core competencies for professional practice, developing a website and electronic newsletter, and establishing training opportunities for practitioners. Future plans for NSPAPPH include development of a professional certification for physical activity practitioners in public health; enhancement of training and professional development opportunities; recruitment of members from national, tribal, state, and local organizations working in public and private sectors; publications of journal articles, reports, and issue briefs; and development of a policy agenda. Implementing these plans will serve to strengthen public health infrastructure for physical activity, thus improving the physical activity behaviors of Americans and the health of the nation.

    Two salient problems in adolescent development are dating violence and suicidal ideation. Theory and empirical research have supported their association in primarily cross-sectional studies. The purpose of this study is to examine the longitudinal association between physical dating violence and suicidal ideation (thoughts or plans) in a cohort of students evaluated annually from Grades 9 to 12. The sample consisted of 556 random-selected students (50.2 % males; 47.5 % White, 37.8 % Black, 11.2 % Latino) who reported dating at least once during the four assessments. Self-reported frequency of suicidal ideation, dating, and physical dating violence perpetration and victimization were assessed each spring from ninth to twelfth grade. We used generalized estimating equations modeling to predict the effects of sex, race, school grade, and physical dating perpetration and victimization on suicidal ideation. Cumulatively, one-fourth of the sample reported suicidal ideation at least once by the end of Grade 12, and approximately half reported physical dating violence. Female gender (OR = 1.7, p = 0.02), physical dating perpetration (OR = 1.54, p = 0.048), physical dating victimization (OR = 2.03, p dating violence perpetration and victimization among high school students. It is important that suicide prevention programs incorporate physical dating violence education and prevention strategies starting early in high school.

    Full Text Available OBJECTIVE: The aim was to investigate the physical and psychological dating violence among adolescents with respect to the profiles of directionality - only man perpetrates, only woman perpetrates, and bidirectional, ie, both perpetrate violence. METHODS: Sample was performed by two-stage cluster selection in public and private school in the city of Recife (PE, Brazil, presenting data on 355 adolescents of both sexes between 15 and 19 years old. Psychological violence was measured in dimensions threat, verbal/emotional, and relational. Statistical analyzes incorporated the sampling weight and the complex sample design. RESULTS: Violence is bidirectional in most forms studied (83.9% and girls reported higher levels of perpetration of physical violence, and boys reported more perpetration of relational violence. CONCLUSION: It was concluded that adolescent dating violence shows a pattern where partners attack each other, both physically and psychologically. Future research should study the patterns of these acts of violence, keeping the adolescent couple as the unit of analysis and exploring the context in which such violence occurs.

  10. Quantum physics reimagined for the general public

    Bobroff, Julien

    2015-03-01

    Quantum Physics has always been a challenging issue for outreach. It is invisible, non-intuitive and written in sophisticated mathematics. In our ``Physics Reimagined'' research group, we explore new ways to present that field to the general public. Our approach is to develop close collaborations between physicists and designers or graphic artists. By developing this new kind of dialogue, we seek to find new ways to present complex phenomena and recent research topics to the public at large. For example, we created with web-illustrators a series of 3D animations about basic quantum laws and research topics (graphene, Bose-Einstein condensation, decoherence, pump-probe techniques, ARPES...). We collaborated with designers to develop original setups, from quantum wave animated models or foldings to a superconducting circus with levitating animals. With illustrators, we produced exhibits, comic strips or postcards displaying the physicists in their labs, either famous ones or even our own colleagues in their daily life as researchers. With artists, we recently made a stop-motion picture to explain in an esthetic way the process of discovery and scientific publication. We will discuss how these new types of outreach projects allowed us to engage the public with modern physics both on a scientific and cultural level and how the concepts and process can easily be replicated and expanded by other physicists. We are at the precise time when creative tools, interfaces, and ways of sharing and learning are rapidly evolving (wikipedia, MOOCs, smartphones...). If scientists don't step forward to employ these tools and develop new resources, other people will, and the integrity of the science and underlying character of research risks being compromised. All our productions are free to use and can be downloaded at www.PhysicsReimagined.com (for 3D quantum videos, specific link: www.QuantumMadeSimple.com) This work benefited from the support of the Chair ``Physics Reimagined

  12. A Public Presentations of Gendered Bodies: A Look at Gay and Lesbian Online Dating Profiles

    Directory of Open Access Journals (Sweden)

    Andrew Latinsky

    2012-10-01

    Full Text Available This paper examines how stereotypes and media presentations related to gender norms influence public presentations of gay men and lesbian women. Using online profiles from the online dating website Match.com, this paper examines the body types daters use to describe themselves, their ideal date, and if the poster has a photograph of themselves on their profile. These profiles are used as a method of observing public presentations that are in a unique situation to be tailored towards notions of publically displayed social desirability. Findings indicate that gay men present their online bodies as stereotypically masculine and athletic, while lesbian women are willing to display a slightly broader range of body types. In addition, regardless of gender, both gay men and lesbian women present their ideal dates as stereotypically attractive, with gay men having a particular affinity for dating athletic men. Regression analysis suggests that intersectional variables such as race and age influence a person’s willingness to display a profile picture in the public arena. Overall, this study concludes that heteronormative standards of masculinity combined with structural influences from both the media and peer groups likely have an impact on gay men’s ideal gendered body, while the comparative exclusion of lesbian women from these media influences allow other experiences of gender norms slightly more freedom.

  13. Importance of physical attractiveness and social assertiveness skills in male homosexual dating behavior and partner selection.

    Science.gov (United States)

    Sergios, P; Cody, J

    It was proposed that a homosexual male would most often expect to date, try to date, and like a partner of physical attractiveness greater than his own. One hundred homosexual men were matched in dyads based on objective physical attractiveness ratings made of their appearance by confederates and by their scores on a social assertiveness questionnaire. The subjects were matched in pairs so that all possible combinations of high and low physical attractiveness and social assertiveness were represented. Each pair of 50 dyads experienced an actual "computer date" through an "afternoon tea dance" arranged by the experimenter. Regardless of the subject's own physical attractiveness and social assertiveness level, the largest determinant of how much he liked his partner and how much he wished to date him again was the partner's physical attractiveness. Neither the physical attractiveness nor social assertiveness of a partner, however, influenced how often a subject subsequently asked the partner out. The results suggest that in such institutions as bars and discos, male homosexuals judge prospective partners on the partner's physical attractiveness. However, other variables besides attractiveness and assertiveness work to produce long-term attraction and relationship formation.

  14. Are systematic reviews up-to-date at the time of publication?

    Systematic reviews provide a synthesis of evidence for practitioners, for clinical practice guideline developers, and for those designing and justifying primary research. Having an up-to-date and comprehensive review is therefore important. Our main objective was to determine the recency of systematic reviews at the time of their publication, as measured by the time from last search date to publication. We also wanted to study the time from search date to acceptance, and from acceptance to publication, and measure the proportion of systematic reviews with recorded information on search dates and information sources in the abstract and full text of the review. A descriptive analysis of published systematic reviews indexed in Medline in 2009, 2010 and 2011 by three reviewers, independently extracting data. Of the 300 systematic reviews included, 271 (90%) provided the date of search in the full-text article, but only 141 (47%) stated this in the abstract. The median (standard error; minimum to maximum) survival time from last search to acceptance was 5.1 (0.58; 0 to 43.8) months (95% confidence interval = 3.9 to 6.2) and from last search to first publication time was 8.0 (0.35; 0 to 46.7) months (95% confidence interval = 7.3 to 8.7), respectively. Of the 300 reviews, 295 (98%) stated which databases had been searched, but only 181 (60%) stated the databases in the abstract. Most researchers searched three (35%) or four (21%) databases. The top-three most used databases were MEDLINE (79%), Cochrane library (76%), and EMBASE (64%). Being able to identify comprehensive, up-to-date reviews is important to clinicians, guideline groups, and those designing clinical trials. This study demonstrates that some reviews have a considerable delay between search and publication, but only 47% of systematic review abstracts stated the last search date and 60% stated the databases that had been searched.

    Mixed-gender friendships, romantic relationships, and sexual behaviors increase during adolescence as a normal part of development. However, some studies have revealed potential risks to these types of social relationships. Different authors have indicated that dating violence among adolescents is an issue for concern. To date, there has been little research on this topic cross-nationally. This study examined and compared the prevalence and characteristics of physical dating violence among young people aged between 15 and 18 years in England and Spain (N = 200 in Spain, N = 199 in England), and how being involved (or not) in this violence relates to romantic relationship quality. Results indicated that approximately 23% of young people reported victimization and 30% reported perpetrating physical dating violence. In both countries, most of those involved in physical dating violence reported involvement in reciprocal violence (displaying both aggression and victimization). Those young people involved in dating violence reported higher levels on scales assessing negative aspects of relationship quality compared with those not involved, but there were no significant differences in positive aspects of relationship quality. Furthermore, different patterns appeared relating to the severity of violence and country. The findings are discussed in terms of their implications for theory and practice.

    2011-04-01

    We analyze the citation distributions of all papers published in Physical Review journals between 1985 and 2009. The average number of citations received by papers published in a given year and in a given field is computed. Large variations are found, showing that it is not fair to compare citation numbers across fields and years. However, when a rescaling procedure by the average is used, it is possible to compare impartially articles across years and fields. We make the rescaling factors available for use by the readers. We also show that rescaling citation numbers by the number of publication authors has strong effects and should therefore be taken into account when assessing the bibliometric performance of researchers.

    We analyze the citation distributions of all papers published in Physical Review journals between 1985 and 2009. The average number of citations received by papers published in a given year and in a given field is computed. Large variations are found, showing that it is not fair to compare citation numbers across fields and years. However, when a rescaling procedure by the average is used, it is possible to compare impartially articles across years and fields. We make the rescaling factors available, for use by the readers. We also show that rescaling citation numbers by the number of publication authors has strong effects and should therefore be taken into account when assessing the bibliometric performance of researchers.

    The purpose of this study is, first, to assess whether high expectation messages (from school, home, and community), and peer norms, were associated with physical dating violence victimization (PDV) among a representative sample of California middle and high school students, and second, to assess whether these associations differed by gender and grade level and/or were mediated by self-efficacy. Data from 7th-, 9th-, and 11th-grade respondents of the 2008-2010 California Healthy Kids Survey (CHKS) were analyzed (N = 85,198). CHKS is an anonymous, school-based cross-sectional survey. Logistic regression was used to calculate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for expectations in each domain (school, community, and home), peers norms, and their cumulative effects on physical dating violence victimization. We examined interactions for expectations and for peer norms by gender and grade level, and tested the mediation effect of self-efficacy. Ten percent of students reported experiencing physical dating violence victimization in the past year. Students who reported high overall expectations (in multiple domains) had significantly lower odds of experiencing dating violence (OR = 0.24, CI = [0.20, 0.28]) compared with those who reported very low expectations. This association held across all expectation domains and peer norms when tested in separate models and also when tested together in a single model. High expectations in the home domain and peer norms showed the lowest odds. Associations between high expectations and dating violence were similar across gender and grade levels. Self-efficacy partially mediated the associations between high expectations and dating violence. Suggestions for future research are presented. © The Author(s) 2014.

  4. Towards a Comprehensive and Up-To-Date Institutional Repository: Development of a Publications Tracking Process

    KAUST Repository

    2016-06-15

    As our repository matured we found that a concerted effort was needed to establish it as a resource that institutional stakeholders knew they could turn to for reliable information about the research outputs produced by researchers affiliated with or funded by our institution. The initial impetus for this project was the adoption of an institutional open access policy, which necessitated a process to track the publications of institutional authors, deposit items with applicable open access licenses, and notify authors when an accepted manuscript was needed. To support this process we developed a local publications tracking system independent of our hosted DSpace repository that regularly queries publisher and indexer APIs for new publications, checks for relevant permissions policies, identifies institutional authors and helps us send manuscript request emails. We also harvested records for past items and modified our repository to accommodate metadata-only records. The success of these tracking and harvesting services in making our repository comprehensive and up-to-date has allowed us to rely on our repository as the key source of publications information for additional integrations that update ORCID records with publication information, populate a PlumX metrics dashboard and, most recently, support the implementation of a current research information system (CRIS).

    Understanding the interrelation among problem behaviors and their change over time is fundamental for prevention research. The Healthy Teens Longitudinal Study followed a cohort of adolescents from Grades 6-12. Prior research identified two distinct trajectories of perpetration of physical dating violence: Low and Increasing. The purpose of this study was to examine whether adolescents in these two trajectories differed longitudinally on other problem behaviors: (1) suicidal ideation and attempts, (2) weapon-carrying and threats with a weapon, and (3) substance use, particularly alcohol and marijuana. The sample consisted of 588 randomly-selected students (52% males; 49% White, 36% Black, 12% Latino). Students completed a self-reported, computer-based survey each spring from Grades 6-12. To examine significant differences by perpetration of physical dating violence trajectory, we used Chi-square test and generalized estimating equations modeling. Across most grades, significantly more students in Increasing than in the Low trajectory reported suicidal ideation and attempts, carried a weapon, and threatened someone with a weapon. Adolescents in the Increasing trajectory also had higher trajectories of alcohol use, being drunk, and marijuana use than those in the Low trajectory. All differences were already significant in Grade 6. The difference in the rate of change between groups was not significant. This longitudinal study highlights that problem behaviors-physical dating violence, suicidal ideation and attempts, weapon carrying and threats, marijuana and alcohol use-cluster together as early as sixth grade and the clustering persists over time. The combination of these behaviors poses a great public health concern and highlight the need for early interventions.

    Bacoside rich juice (BRJ) was developed using date syrup as base. BRJ was evaluated for physicochemical, sensory attributes and its effect on physical endurance. Overall acceptability of BRJ and date syrup juice (DSJ) was good according to hedonic scale/ratings. Twenty four adult male Wistar rats were divided into 4 groups (n = 6). Sedentary (Group I) and control (Group II) group rats were allowed to drink water whereas DSJ and BRJ group rats were provided free access to drink DSJ (Group III) and BRJ (Group IV) for 14 days and were subjected to weight-loaded forced swim test (WFST) for every alternate day in order to evaluate the physical endurance. Both BRJ and DSJ group rats swimming efficiency was improved by 3 and 2 folds respectively in comparison with control group on day- 15. Improved physical endurance in BRJ group is due to reduced malondialdehyde levels in brain, liver and muscle tissues by 16.50 %, 17.88 % and 30.20 %, respectively, compared to DSJ group (p < 0.01). In addition, administration of BRJ significantly protected the hepatic and muscle glycogen levels and reduced the levels of lactic acid in comparison to DSJ group. Hence, the present study clearly indicates that BRJ is an effective anti-fatigue drink ameliorates the various impairments associated with physical endurance.

    The observation bands of the 5 meter Dome A Terahertz Explorer (DATE5) are primarily over the wavelength of 350 and 200 μm. However, the pointing performance of DATE5 is affected by the unsteady wind, which either acts directly on the telescope structure or transmits through the ice and foundation. According to the above performance requirements of DATE5, the pointing error caused by the wind disturbance must be less than 2 arcsec. The main influence of the disturbances acting on the telescope is forces and torques due to wind gusts. Alternating forces and torques cause displacements of the telescope as well as structural oscillations. Both effects lead to pointing errors and therefore have to be compensated as much as possible by the main axes servo controllers. Wind acting on the telescope can be treated as random event, whose expected values depend on the specific site. The wind velocity throughout a given time interval can be described as a randomly varying velocity superimposed upon a constant average or mean velocity. For the dynamic analysis, the two components are separated and only the fluctuating component is used. In this paper, the dynamic analysis (mode analysis and spectrum analysis) of DATE5 is carried out based on the physically realistic environmental disturbances of dome A.

    Full Text Available Most of the date fruits are processed traditionally in Iran. It becomes imperative to characterize the fruits with a view of understanding the properties that may affect the design of machines to handle their processing. The objectives of this study were to find the basic physical properties of date fruit at different storage time. Some physical properties of the Iranian Stamaran date variety were measured at the tamr stage of maturity for pitted dates during 6 months storage (25 °C of temperature and 75% of humidity. The results showed that length of the samples decreased by 8.31% from 39.21 to 35.95 mm, and no significant change for width and thickness. Mean mass and volume of the fruit did not change significantly. The projected area along length (PL did not change significantly, but projected areas along width (PW and along thickness (PT decreased by 4.26% from 647.41 to 619.8, and 8.32% from 666.89 to 611.43 mm2, respectively. The fruit density, bulk density, porosity and sphericity did not change significantly. The geometric mean diameter and surface area decreased by 5.01%, from 25.53 to 24.25 mm, and 9.57%, from 2049.3 to 1853.1 mm2, respectively. The mean coefficients of static friction increased significantly from 0.36 to 0.38, 0.33 to 0.35 and 0.42 to 0.45 on steel, galvanized iron, and plywood, respectively.

    Intimate partner violence often begins during the courtship stage of romantic relationships. Although some relationships dissolve as a result of aggression, other relationships remain intact, increasing the risk for escalated violence. The present study identified factors predictive of individual differences in emerging adults' commitment to physically aggressive or sexually coercive dating relationships. Specifically, Rusbult's Investment Model of romantic relationships (e.g., investment, satisfaction, quality of alternatives, and commitment) was applied to a longitudinal sample of 148 young adult women who reported experiencing aggression or coercion from their current partners. To further explain commitment within aggressive or coercive dating relationships, rejection sensitivity and anxious and avoidant romantic relational styles were included as predictors of the Investment Model variables. A more avoidant romantic style indirectly predicted commitment through relationship satisfaction and investment. Both commitment and rejection sensitivity significantly predicted continuing an aggressive or coercive relationship 6 months later. The present study improves our understanding of the processes involved in relationship commitment. Continuing to understand these processes will inform interventions that seek to help women who have decided to end aggressive or coercive dating relationships.

    Despite the well-known benefits of youths engaging in 60 or more minutes of daily physical activity, physical inactivity remains a significant public health concern. The 2008 Physical Activity Guidelines for Americans (PAG) provides recommendations on the amount of physical activity needed for overall health; the PAG Midcourse Report (2013) describes effective strategies to help youths meet these recommendations. Public health professionals can be dynamic change agents where youths live, learn, and play by changing environments and policies to empower youths to develop regular physical activity habits to maintain throughout life. We have summarized key findings from the PAG Midcourse Report and outlined actions that public health professionals can take to ensure that all youths regularly engage in health-enhancing physical activity.

    Although research on dating violence is growing, little is known about the distinct developmental trajectories of dating violence during adolescence. The current study identifies trajectories of physical dating violence victimization and perpetration that boys and girls follow from sixth to twelfth grade, examines the overlap of these trajectories, and characterizes them by perceptions of a caring dating relationship and acceptability of dating aggression. The sample consisted of randomly selected sixth graders from nine schools in Northeast Georgia (n = 588; 52 % boys; 49 % White, 36 % African American, 12 % Latino) who completed yearly surveys from Grades 6-12. We used latent class mixture modeling to identify the trajectories and generalized estimating equations models to examine the acceptability of dating aggression by dating violence trajectories. Participants followed two trajectories of dating violence victimization (boys: low and high; girls: low and increasing) and two of perpetration (boys and girls: low and increasing). When examining the joint trajectories of victimization and perpetration, a similar proportion of boys (62 %) and girls (65 %) were in the low victimization and low perpetration group and reported the lowest acceptance of dating aggression. The same proportion of boys and girls (27 %) were in the high/increasing victimization and perpetration group, and reported the highest acceptance of dating aggression. However, acceptance of dating aggression decreased from Grade 6-12 for all groups, even for those whose trajectory of dating violence increased. Victimization and perpetration were associated with reporting a less caring dating relationship. Results highlight the importance of focusing prevention efforts early for adolescents who follow this increasing probability of physical dating violence.

    Public open spaces such as parks and green spaces are key built environment elements within neighbourhoods for encouraging a variety of physical activity behaviours. Over the past decade, there has been a burgeoning number of active living research studies examining the influence of public open space on physical activity. However, the evidence shows mixed associations between different aspects of public open space (e.g., proximity, size, quality) and physical activity. These inconsistencies hinder the development of specific evidence-based guidelines for urban designers and policy-makers for (re)designing public open space to encourage physical activity. This paper aims to move this research agenda forward, by identifying key conceptual and methodological issues that may contribute to inconsistencies in research examining relations between public open space and physical activity.

    2009-07-01

    This study examined parenting and peer predictors of physical dating violence perpetration during early adolescence and tested moderation among these predictors and gender. Participants were 2,824 ethnically diverse sixth-grade students with a recent boyfriend/girlfriend who was part of a multisite, longitudinal investigation of the development and prevention of violence among middle school students. Those students who reported having a boyfriend/girlfriend reported significantly more drug use and delinquent activity and were more likely to be male. Twenty-nine percent of youth with a boyfriend/girlfriend reported perpetrating physical aggression against their boyfriend/girlfriend. Parenting and peer variables were significant predictors of physical dating violence. However, gender moderated the association between parenting practices and physical dating violence, with parental monitoring inversely linked to dating violence for boys and parent support for nonaggression inversely linked to dating violence for girls. Parent support for aggression also moderated the association between peer deviancy and reported perpetration. Finally, gender moderated the interaction between peer deviancy and parent support for nonaggressive solutions.

  2. Physical Dating Violence: the potential understating value of a bi-factorial model

    Full Text Available National and international studies have pointed out Conflict Tactics Scale (CTS, Straus, 1979, 1996 as one of the most widely used measures for assessing the strategies used in situations of conflict within young couples. Nevertheless, there is not any conclusive result about its structure. Especially the physical dating violence scale has undergone several structural analyses providing monofactorial and bifactorial structures. The aim of this study was focusing on the validation of structural models using confirmatory factorial analysis (CFA of CTS within adolescent couples, considering the differences between boys and girls and between aggressors and victims. 3258 adolescents, aged 15-21, were selected using a stratified random sample and interviewed using an adaptation of the CTS questionnaire. The results pointed out that it is not possible to identify a single model fit, but boys and girls, aggressor and victims, have the same pattern: a bifactorial model which establishes different but correlated moderate aggressive behaviors and severe aggressive behaviors. These results are discussed in terms of the potential value of this two factor structure for understanding the phenomenon.

    This short-term longitudinal study examined whether the association between bullying perpetration and later physical dating violence perpetration and mediators of that association (via anger, depression, anxiety, and social status), varied depending on level of bullying victimization. Differences have been noted between those who bully but are not victims of bullying, and those who are both bullies and victims. These differences may influence dating violence risk and the explanations for why bullying leads to dating violence. Data were from dating adolescents in three rural counties who completed self-administered questionnaires in the fall semester of grades 8-10 and again in the spring semester. The sample (N = 2,414) was 44.08% male and 61.31% white. Bullying perpetration in the fall semester predicted physical dating violence perpetration in the spring semester when there was no bullying victimization, but not when there was any bullying victimization. Bullying perpetration was positively associated with anger at all levels of bullying victimization and with social status when there was no or low amounts of victimization; it was negatively associated with social status at high levels of victimization. Bullying victimization was positively associated with anger, depression, and anxiety at all levels of bullying perpetration. Anger mediated the association between bullying perpetration and dating violence, regardless of level of victimization; depression, anxiety, and social status did not mediate the association at any level of bullying victimization. The findings have implications for dating violence prevention efforts and for future research on the link between bullying and dating violence. © 2015 Wiley Periodicals, Inc.

  9. Physics Public Engagement--Not Just for Kids Anymore!

    2012-03-01

    Engaging the community with physics is a way of developing and supporting a vibrant and strong physics department at Angelo State University. The Society of Physics Students chapter has been actively involved in numerous public engagement activities for over 10 years. These efforts claim to focus on ``enhancement of attitudes'' for the audience participants, but the benefits of these public engagement opportunities go well beyond getting the younger students excited about science. The more critical need addressed by outreach programs such as ours is getting the undergraduate student presenters engaged as professional scientists, immersed in the true culture of scientific citizenship, and taking ownership of not only the physics they present, but also the impact that they potentially have on the students with which they interact. As undergraduate physics programs across the nation find themselves facing programmatic cuts, the value of engaging undergraduate students in purposeful service as a means of retention in the major should be considered as a standard part of a successful program curriculum.

    One of the components of evidence-based practice (EBP) is reading the literature. The purpose of this investigation was 1) to determine which publications are read most frequently by physical therapists (PTs), 2) to identify employment and education characteristics related to reading patterns, and 3) to determine how PTs use information gained from reading professional publications. A survey was constructed, pretested, revised, and then mailed to a random sample of 1,000 physical therapists, 500 from the general American Physical Therapy Association (APTA) membership and 500 from the combined Geriatric and Orthopedic section memberships. The data were analyzed with descriptive statistics. After all mailings, 43.3% of the sample responded. Of those responding, 66.3% were employed as clinicians, 14.7% as clinician-administrators, 6% as educators, and 4.9% as administrators. Overall, and for clinicians, the two most frequently read professional publications were non peer-reviewed. For clinician groups "patient management" was among the top two most selected uses of information from reading professional publications. Educators and those with an advanced doctorate indicated "class lectures" as either their second most frequently selected use or tied for first with "keeping current." Only educators and those with or pursuing an advanced doctorate reported using information from reading professional publications for "research ideas" or "research methods" among their top five uses. Slightly more than 10% of the respondents cited a peer-reviewed published article as having been most influential on their practice. Non peer-reviewed professional publications appear to serve as a more frequent source of information for "patient management" than do peer-reviewed publications. Efforts to increase the use of EBP need to be explored and evaluated for impact on physical therapists' practice.

  12. Presenting particle physics and quantum mechanics to the general public

    CERN Document Server

    Strauss, J

    2015-01-01

    The job of a physicist is to describe Nature. General features, hypotheses and theories help to describe physics phenomena at a more abstract, fundamental level, and are sometimes tacitly assigned some sort of real existence; doing so appears to be of little harm in most of classical physics. However, missing any tangible connection to everyday experience, one better always bears in mind the descriptive nature of any efforts to grasp the quantum. And elementary particles interact in the quantum world, of course. When communicating the world of elementary particles to the general public, the Bayesian approach of an ever ongoing updating of the depiction of reality turns out to be virtually indispensable. The human experience of providing a series of increasingly better descriptions generates plenty of personal pleasures, for researchers as well as for amateurs. A suggestive analogy for improving our understanding of the world, even the seemingly paradoxical quantum world, may be found in recent insight into ho...

    The dates of publication of Hubert Ludwig's (1852-1913) comprehensive monograph Die Seewalzen [= Sea cucumbers] are reviewed. The precise publication dates of his volume, originally published in 16 fascicles and 8 parts/issues, delivered between 1889 and 1892, has been re-examined. Additionally, a short biographical note on Hubert Ludwig's life and a discussion of all new taxa introduced by him in his monograph is given.

    Physical activity (PA) provides numerous physiological and psychosocial benefits. However, lifestyle changes, including reduced PA opportunities in multiple settings, have resulted in an escalation of overweight and obesity and related health problems. Poor physical and mental health, including metabolic and cardiovascular problems is seen in progressively younger ages, and the systematic decline in school PA has contributed to this trend. Of note, the crowded school curriculum with an intense focus on academic achievement, lack of school leadership support, funding and resources, plus poor quality teaching are barriers to PA promotion in schools. The school setting and physical educators in particular, must embrace their role in public health by adopting a comprehensive school PA program. We provide an overview of key issues and challenges in the area plus best bets and recommendations for physical education and PA promotion in the school system moving forward.

  15. Physical solutions to the public goods dilemma in bacterial biofilms

    Bacteria frequently live in densely populated surface-bound communities, termed biofilms. Biofilm-dwelling cells rely on secretion of extracellular substances to construct their communities and to capture nutrients from the environment. Some secreted factors behave as cooperative public goods: they can be exploited by non-producing cells. The means by which public good producing bacteria avert exploitation in biofilm environments are largely unknown. Using experiments with Vibrio cholerae, which secretes extracellular enzymes to digest its primary food source, the solid polymer chitin, we show that the public goods dilemma may be solved by two dramatically different, physical mechanisms: cells can produce thick biofilms that confine the goods to producers, or fluid flow can remove soluble products of chitin digestion, denying access to non-producers. Both processes limit the distance over which enzyme-secreting cells provide a benefit to neighbors, resulting in preferential benefit to nearby clonemates. Our results demonstrate how bacterial physiology and environmental conditions can interact with social phenotypes to influence the evolutionary dynamics of cooperation within biofilms.

    International audience; Physical layer security is an emerging security technology that achieves perfect secrecy data transmission between the intended network nodes, while the eavesdrop- ping malicious nodes obtain zero information. The so-called secrecy capacity can be improved using friendly jammers that introduce extra interference to the eavesdropping ma- licious nodes while the interference to the intended desti- nation is limited.

    Context. We present very early optical lightcurves beginning 10 days before maximum of the Type IIn supernova 1998S, covering the first four months after discovery. Aims. We examine the light evolution and try to compare the lightcurves to two analytical models(Nakar & Sari(2010) and Rabinak & Waxman(2011)) for a red supergiant star. Methods. The photometry was carried at the 60-cm telescope of the Xinglong Station of China. Broadband filters Johnsons B, V and Cousins R were used. Results. The magnitude rose for the first few days and then dropped slowly afterwards. The two di?erent models we use can fit the early lightcurves very well. The explosion date derived from the models is within the range of 1998 March 1.34 - 2.64(JD 2450873.84 - JD 2450875.14.) The radius of the progenitor is found to be ~ 300 Rsun and ~ 2000 Rsun for the model of Nakar & Sari(2010) and Rabinak & Waxman(2011) respectively. The constraint on mass and energy is not strong. The ranges of these two parameters are within...

    The growing evidence on the association between consumption of sugar-sweetened beverages, obesity and other chronic diseases has highlighted the need to implement policy actions that go beyond programs exclusively focused on individual responsibility. In order to protect their commercial goals in Latin America, the sugar-sweetened beverage industry practices intense lobbying at high government levels in several countries across the region. This strategy is accompanied by corporate social responsibility programs that fund initiatives promoting physical activity. These efforts, although appearing altruistic, are intended to improve the industry's public image and increase political influence in order to block regulations counter to their interests. If this industry wants to contribute to human well being, as it has publicly stated, it should avoid blocking legislative actions intended to regulate the marketing, advertising and sale of their products.

    The high risk of perpetrating physical dating violence, bullying, and sexual harassment by adolescents exposed to domestic violence points to the need for programs to prevent these types of aggression among this group. This study of adolescents exposed to domestic violence examined whether these forms of aggression share risk factors that could be targeted for change in single programs designed to prevent all three types of aggression. Analyses were conducted on 399 mother victims of domestic violence and their adolescents, recruited through community advertising. The adolescents ranged in age from 12 to 16 years; 64 % were female. Generalized estimating equations was used to control for the covariation among the aggression types when testing for shared risk factors. Approximately 70 % of the adolescents reported perpetrating at least one of the three forms of aggression. In models examining one risk factor at a time, but controlling for demographics, adolescent acceptance of sexual violence, mother-adolescent discord, family conflict, low maternal monitoring, low mother-adolescent closeness, low family cohesion, depressed affect, feelings of anger, and anger reactivity were shared across all three aggression types. In multivariable models, which included all of the risk factors examined and the demographic variables, low maternal monitoring, depressed affect and anger reactivity remained significant shared risk factors. Our findings suggest that programs targeting these risk factors for change have the potential to prevent all three forms of aggression. In multivariable models, poor conflict management skills was a risk for bullying and sexual harassment, but not dating violence; acceptance of dating violence was a risk for dating violence and bullying, but not sexual harassment; and none of the examined risk factors were unique to aggression type. The study's implications for the development of interventions and future research are discussed.

    AstroMcGill was founded in 2011 by an enthusiastic group of undergraduate students, graduate students and post-doctoral fellows. It serves as the education and public outreach (EPO) branch of the astronomy group within the Physics Department at McGill University in Montreal, Quebec. Over the last five years, AstroMcGill has grown from organizing sporadic visits in a couple primary schools to running a successful inquiry-based outreach programme for grade 4-6 students, the McGill Space Explorers. During the same time span, the attendance at public AstroNight lectures ramped up from attracting a few dozen people to over 500 people each month. We will highlight the recent successes of the programme and our best guesses for the reasons behind this success. We will also discuss the challenges of working in a bilingual city as we juggle our majority anglophone volunteers, a mandatory french science curriculum for primary school children and the (somewhat) overlapping English- and French-speaking communities in the city.

    Full Text Available This study focuses on understanding constraints on leisure time physical activity (LTPA on a university campus. The survey study was conducted with public university students (n=563 living in dormitories. The 38-item, 8-dimension Leisure Time Physical Activity Constraints (LTPA-C Scale was used to investigate factors limiting LTPA. Age, gender, working status (i.e. part-time, non-working, program type (i.e. morning education, evening education, relationship status (i.e. in a relationship, not in a relationship, monthly expenses and body mass index (BMI category (i.e. underweight, normal weight, overweight, obese are key variables believed to affect LTPA-C. An initial confirmatory factor analysis was conducted to validate the structure of the scale, and frequency analysis, Pearson’s Correlation and t-tests were conducted to analyze the survey responses. Results showed the hierarchy of constraints for males (from high to low to be as follows: society, income, time, facility, willpower, skill perception, family, body perception. The hierarchy was nearly identical for females, except ‘willpower’ was found to be a greater constraint than ‘facility’; moreover, the differences in the rates at which males and females perceived ‘facility’ and ‘willpower’ to be constraints were statistically significant.The study findings indicate that by taking steps to improve the infrastructure of university campus facilities and organize group activities, university management can provide motivation and social support that can help to increase university student participation in LTPA.

    Walking for health is recommended by health agencies, partly based on epidemiological studies of self-reported behaviors. Accelerometers are now replacing survey data, but it is not clear that intensity-based cut points reflect the behaviors previously reported. New computational techniques can help classify raw accelerometer data into behaviors meaningful for public health. Five hundred twenty days of triaxial 30-Hz accelerometer data from three studies (n = 78) were employed as training data. Study 1 included prescribed activities completed in natural settings. The other two studies included multiple days of free-living data with SenseCam-annotated ground truth. The two populations in the free-living data sets were demographically and physical different. Random forest classifiers were trained on each data set, and the classification accuracy on the training data set and that applied to the other available data sets were assessed. Accelerometer cut points were also compared with the ground truth from the three data sets. The random forest classified all behaviors with over 80% accuracy. Classifiers developed on the prescribed data performed with higher accuracy than the free-living data classifier, but these did not perform as well on the free-living data sets. Many of the observed behaviors occurred at different intensities compared with those identified by existing cut points. New machine learning classifiers developed from prescribed activities (study 1) were considerably less accurate when applied to free-living populations or to a functionally different population (studies 2 and 3). These classifiers, developed on free-living data, may have value when applied to large cohort studies with existing hip accelerometer data.

    Child maltreatment is one of the most commonly examined risk factors for violence in dating relationships. Often referred to as the intergenerational transmission of violence or cycle of violence, a fair amount of research suggests that experiencing abuse during childhood significantly increases the likelihood of involvement in violent relationships later, but these conclusions are primarily based on correlational research designs. Furthermore, the majority of research linking childhood maltreatment and dating violence has focused on samples of young people from the United States. Considering these limitations, the current study uses a rigorous, propensity score matching approach to estimate the causal effect of experiencing child physical abuse on adult dating violence among a large sample of South Korean emerging adults. Results indicate that the link between child physical abuse and adult dating violence is spurious rather than causal. Study limitations and implications are discussed.

  12. Animate Objects: How Physical Motion Encourages Public Interaction

    Science.gov (United States)

    Ju, Wendy; Sirkin, David

    The primary challenge for information terminals, kiosks, and incidental use systems of all sorts, is that of getting the "first click" from busy passersby. This paper presents two studies that investigate the role of motion and physicality in drawing people to look and actively interact with generic information kiosks. The first study was designed as a 2x2 factorial design, physical v. on-screen gesturing and hand v. arrow motion, on a kiosk deployed in two locations, a bookstore and a computer science building lobby. The second study examined the effect of physical v. projected gesturing, and included a follow-up survey. Over twice as many passersby interacted in the physical v. on-screen condition in the first study and 60% more interacted in the second. These studies, in concert, indicate that physical gesturing does indeed significantly attract more looks and use for the information kiosk, and that form affects people's impression and interpretation of these gestures.

    The Public Health Responsibility Deal (RD) in England is a public-private partnership involving voluntary pledges between government, industry, and other organisations to improve public health by addressing alcohol, food, health at work, and physical activity. This paper analyses the RD physical activity (PA) pledges in terms of the evidence of their potential effectiveness, and the likelihood that they have motivated actions among organisations that would not otherwise have taken place. We systematically reviewed evidence of the effectiveness of interventions proposed in four PA pledges of the RD, namely, those on physical activity in the community; physical activity guidelines; active travel; and physical activity in the workplace. We then analysed publically available data on RD signatory organisations' plans and progress towards achieving the physical activity pledges, and assessed the extent to which activities among organisations could be attributed to the RD. Where combined with environmental approaches, interventions such as mass media campaigns to communicate the benefits of physical activity, active travel in children and adults, and workplace-related interventions could in principle be effective, if fully implemented. However, most activities proposed by each PA pledge involved providing information or enabling choice, which has limited effectiveness. Moreover, it was difficult to establish the extent of implementation of pledges within organisations, given that progress reports were mostly unavailable, and, where provided, it was difficult to ascertain their relevance to the RD pledges. Finally, 15 % of interventions listed in organisations' delivery plans were judged to be the result of participation in the RD, meaning that most actions taken by organisations were likely already under way, regardless of the RD. Irrespective of the nature of a public health policy to encourage physical activity, targets need to be evidence-based, well

    A gradual decrease in energy output for adults in the Western countries has been observed through the XXth century. The mechanization in industrial societies result in a decline of customary physical activity and consequently in the potentially vicious spiral of inactivity leading to deconditioning and thence, via loss of physiological capacity, to a further reduction in activity. The sedentary life has injurious effects on the health of individuals and specially increase the risks of cardiovascular disease. Furthermore there is a supposed relation between inactivity with obesity and hyperlipemia in young people and with osteoporosis in elderly. In contrast, many papers showed that high levels of physical activity have been associated with a diminished occurrence of hypertension, coronary artery disease, non insulin-dependent diabetes, colon cancers... In addition physical fitness is obviously related to the quality of life. Because of all these reasons several developed countries have elaborated plans of physical reconditioning for their people. In France some experimental actions have been completed but any national programme has been determined. Moreover it is now crucial to promote scientific researches about the fundamental biological mechanisms which explain the beneficial effects of physical training on the prevention and/or the treatment of several illness.

    Many physical therapists depend on their professional journals for high-quality evidence. The purpose of this study was to evaluate the rigor of research and review articles in 4 national physical therapy journals. All articles in 6 consecutive issues of the Australian Journal of Physiotherapy, Physical Therapy, Physiotherapy, and Physiotherapy Canada, published between January 2000 and June 2001 (N=179), were reviewed. One trained reviewer identified the type and purpose of each article and assessed the rigor of treatment and review articles according to explicit criteria. The majority of articles reviewed were original studies (56%). The majority of the research articles that dealt with human health care (66%) addressed topics that were not directly applicable to the provision of patient care such as measurement topics and studies on subjects without identified pathologies or impairments. Of the 179 journal articles, 19 met the standards for rigor (11%). The majority of these articles dealt with treatment. The pass rate per journal was as follows: Australian Journal of Physiotherapy, 10% (4/42); Physical Therapy, 15% (7/47); Physiotherapy, 12% (4/34); and Physiotherapy Canada, 7% (4/56). Because such a small percentage of articles in these professional journals were identified as having direct application to patient care, physical therapists should attempt to access other sources of information to find additional high-quality evidence. A larger sample with a greater number of issues per journal may have yielded different results and indicated different trends, and further research appears to be warranted.

    The names and dates of the publications of Brachyura of Guérin (Guérin-Méneville from 1836) are reviewed, and previously unidentified or overlooked names are identified. Several identical new names used in multiple publications by Guérin (also under the name Guérin-Méneville), and others that appeared in the same year necessitated the accurate determination of publication dates to establish priority. The authorships of three names should be credited to Guérin (1832): Gecarcinus lateralis (Gecarcinidae), Halimus aries (Majidae), and Libinia spinosa (Epialtidae), the first previously attributed to Fréminville (1835), the last two to H. Milne Edwards (1834). The overlooked genus- and species-group names Cyclocarcinus pinnotheroides Guérin-Méneville, 1838, are determined to be senior subjective synonyms of the genus- and species-group names Hapalonotus reticulatus (De Man, 1879) (Pilumnidae). Applying Article 23.9.1 of the International Code of Zoological Nomenclature, precedence is reversed between the genus-group names and the correct name is Hapalonotus pinnotheroides (Guérin-Méneville, 1838). Current and widespread use of the genus-group name Thalamita Latreille, 1829 (31 March) (Portunidae) is threatened by the overlooked Thalamites Guérin, 1829 (21 March), and the precedence of the names is also reversed to maintain usage of the former. The genus-group name Eurypodius Guérin (Inachidae) is shown to have been established in 1828, not 1825. Included is a complete bibliography of the publications in which Guérin (also under Guérin-Méneville) established new names for Brachyura, with their accurate publication dates.

    The prevalence of alcohol use and dating violence are shockingly high among male college students, making this a particularly high-risk group for alcohol-related aggression. Expanding upon previous research, the current study examined the relations between three indicators of alcohol use and three types of dating violence among 204 male college students. We also examined whether hazardous drinkers reported more violence perpetration than non-hazardous drinkers. Results demonstrated that alcohol use was related to all types of aggression, and hazardous drinkers are at greater risk of violence perpetration than non-hazardous drinkers. Implications for dating violence prevention programs and future research are discussed.

    2013-03-01

    Full Text Available BACKGROUND: Many studies and scientific evidence confirm a positive effect of physical activity on the quality of life and human health. Physical activity, which is also one of the key factors preventing mass non-communicable diseases, is decreasing in Europe, including the Czech Republic, both in children and adults. Serious health consequences for the population and economy of the countries are a reason for a discussion about including the low level of physical activity among public policy issues and a higher allocation of public sources into the area of physical activity promotion. OBJECTIVES: The main objective of the paper is to determine whether the low level of physical activity is a public policy issue. An issue that should by systematically addressed by national, regional as well as local policy. METHODS: Through the policy analysis approach we conducted a content analysis of 25 systematically selected foreign national strategies aimed at the issue of physical activity promotion. The data source was an internal database of the World Health Organization - the International Inventory of Documents on Physical Activity Promotion. The content analysis of the strategies was performed using the Atlas.ti software tool. RESULTS: During a content analysis of 25 foreign strategies a total of 411 text segments (quotations relating to the low level of physical activity were selected. These text segments showed five basic features of a public policy issue according to a conceptual framework developed by Bardach (2000 and Patton and Sawicky (1993 - 1 affects the lives of a significant number of people of a society; 2 is analysable; 3 can be solved through public policy tools; 4 the primary cause or problem can be defined; 5 cannot be solved easily and quickly. CONCLUSIONS: The results indicate that the low level of physical activity is a public policy issue that must be systematically addressed at national level.

    The physical and chemical properties of the date (Phoenix dactylifera L.) fruit seeds from seven date samples (Soukari, Soulag, Barhi, Khulas, Rozaiz, Soughi and Monaif) were evaluated. Energy values of dried and ground seeds were found between 4340 kcal/kg (Barhi cv) and 4795 kcal/kg (Rozaiz cv). Also, while crude oil content of seeds were established between 4.68% (Khulas cv) and 7.96% (Monaif cv), crude protein contents were found at the levels between 3.71% (Soulag cv) and 5.47% (Barhi cv). The antioxidant activity of seeds obtained from different date fruits changed between 78.03 (mg/ml) (Monaif cv) and 79.94 (mg/ml) (Barhi cv). In addition, the total phenol contents of seeds were found between 1.98 mg gallic acid equivalents (GAE)/100 g (Barhi cv) and 4.65 mg GAE/100 g (Soughi cv). The most abundant fatty acids of the date seed oils were oleic, lauric, myristic, palmitic and stearic acids. Ca, Mg, K and P contents of date seeds were found at the high concentrations.

    Quotations in Brazilian journals are mainly obtained from national articles (articles from Brazilian journals); thus, it is essential to determine how frequently these articles reference Brazilian journals. This study sought to verify how frequently national papers are cited in the references of three Brazilian physical therapy journals. All references for articles published in Fisioterapia em Movimento, Fisioterapia e Pesquisa and Revista Brasileira de Fisioterapia between 2010 and 2012 were evaluated. In particular, the numbers of national articles and international articles (articles from international journals) cited in these references were determined. A total of 13,009 references cited by 456 articles were analyzed, and 2,924 (22.47%) of the cited works were national articles. There were no significant differences among the three examined years. A total of 36 (7.89%) articles did not cite national articles, whereas 65 (13.25%) articles cited more national articles than international articles. On average, 22.47% of the works cited by the evaluated articles were national articles. No significant differences were detected among the three analyzed years.

    Many large scientific projects and scientific centres incorporate some kind of outreach programme. Almost all of these outreach programmes include public scientific lectures delivered by practising scientists. In this article, we examine such lectures from the perspectives of: (i) lecturers (7) who are practising scientists acknowledged to be good public lecturers and (ii) audiences composed of high-school students (169) and high-school physics teachers (80) who attended these lectures. We identify and discuss the main goals as expressed by the lecturers and the audiences, and the correspondence between these goals. We also discuss how the lecturers' goals impact on the design of their lectures and examine how the lecture affects audiences with different attitudes towards (and interests in) physics. Our findings suggest that the goals of the participating lecturers and the expectations of their audiences were highly congruent. Both believe that a good public scientific lecture must successfully communicate state-of-the-art scientific knowledge to the public, while inspiring interest in and appreciation of science. Our findings also suggest that exemplary public scientific lectures incorporate content, structure and explanatory means that explicitly adhere to the lecturers' goals. We identify and list several design principles.

    Individuals with disabilities experience a disproportionate rate of chronic disease and are more likely to lead sedentary lifestyles than the general population. Multiple complex factors likely contribute to these disparities, including structural, socioeconomic and attitudinal barriers that impede broad participation of individuals with disabilities in health and wellness promotion programs. Public health initiatives aimed at mitigating these health disparities emphasize improved access to physical activity and sports opportunities. Given its visibility, the Paralympic Movement provides an opportunity to transform how society conceptualizes the relationship of disability to physical fitness. The Paralympics also serve as a catalyst for public health education and program development. Already, public policies and governmental regulations are expanding grassroots sports opportunities for youth and adults with disabilities, thus promoting inclusive opportunities for participation in physical activity.

    The present study examined differences in dietary habits and physical activity levels between students attending private and public high schools in Jordan. A total of 386 secondary-school males and 349 females aged 14-18 years were randomly recruited using a multistage, stratified, cluster sampling technique. Dietary habits and physical activity level were self-reported in a validated questionnaire. The prevalence of obesity was significantly higher among adolescents in private (26.0%) than in public schools (16.7%). The frequency of breakfast intake was significantly higher among adolescents in private schools, whereas French fries and sweets intake was significantly higher in public schools. Television viewing showed a significant interaction with school type by sex. A higher rate of inactivity was found among students attending private schools. Despite a slightly better overall dietary profile for students in private schools, they had a higher rate of overweight and obesity compared with those in public schools.

    Despite the increasing number of non-marital romantic relationships in developed countries, little is known about their effects on health-related behaviors. This paper examined the impact of relationship status (single, dating, cohabiting or married) on physical activity. Three possible mechanisms underlying this association were discussed: social control and support by the partner, time restrictions and the release from the marriage market. Data were obtained from the German Socio-Economic Panel (GSOEP), a random sample of individuals living in private households in Germany. Both random-effects and fixed-effects logit models were estimated. The random-effects analyses referred to 30,201 individuals and the fixed-effects analyses referred to 11,568 individuals who were observed for up to 19 years. After adjusting for age, measurement period and the presence of children, fixed-effects estimates showed reduced physical activity for each type of relationship for both men and women. The effects were strongest for married couples and weakest for dating couples, and remained similar after controlling for discretionary time. However, the effects found partly depended on age: for men, the negative impacts of cohabitation and marriage on physical activity became weaker with increasing age and shifted to positive impacts. For women, the negative effect of marriage on physical activity also decreased but stayed negative into old age. The results suggest that the release from the marriage market may cause the negative effects of relationships on physical activity. Social support and social control may play a role in older age, whereas the amount of discretionary time seems to be of minor importance for explaining relationship effects on physical activity. If the results will be validated by other studies there will be valuable implications for health promotion programs.

  18. The interrelationship of the science of health physics and the art of radioactive materials management - an international public policy perspective

    1996-06-01

    Dissemination of scientific data contemplated to affect public policy issues can be viewed as a translation of technology into a form of art. Due to the public`s perception of all things radioactive, when the science is health physics, and the form of art is radioactive materials management (efficient enough to be embraced by the public), the complexities of the task become even more convoluted than with other issues. There is no historic analogy for the transliteration difficulties faced by the Society`s membership in their continuing effort to provide meaningful data and information. Unfortunately, the significance of the practitioner`s contribution to the larger issue of global radioactive materials management will continue to be impacted by forces outside of their control. The extent of that impact will be determined solely by the Society`s ability to identify the presence of these non-scientific influences and consider them as indispensable variables in developing risk assessment models. The exceptional quality of the Society`s contributions to date notwithstanding, the reality of financial impacts vs. the profession`s scientific contributions to the overall management task, regardless how sound, cannot be overlooked. The absence of international consensus on safe levels of exposure thresholds coupled with lobbying efforts by special interest groups exploiting this scientific indecision; the recent exclusion, by the insurance industry of all radioactive matter in comprehensive general liability policies which negates even conservative threshold assumptions; the entire issue of surety and indemnification for the professional and the public; and the financial ramifications of asset value of real property affected by any radionuclide, are just some of the realities which could dilute the significance of this important science, which, by the by, serves as the foundation of the art form.

    Radiocarbon dating can be used to determine the age of objects that contain components that were once alive. In the case of human remains, a radiocarbon date can distinguish between a crime scene and an archeological site. Documents, museum artifacts and art objects can be dated to determine if their age is correct for the historical context. A radiocarbon date does not confirm authenticity, but it can help identify a forgery.

    After the Fukushima Daiichi Nuclear Accident, the importance of bottom-up and two-way dialogue between scientists and the public has been recognized. In such dialogue, information provided must accurately match the public's interest and ability regarding science and technology. We have started to investigate what people want to know about physics. Some were interested in energy security (a particular concern in Japan), but others were concerned about radioactivity in food and natural radiation background. The conversations revealed that physicists often give insufficient explanations of the biological effects of radiation and highlighted key points for physicists to make when talking with the public.

    Low-income and minority groups in the United States have low levels of physical activity that contribute to health inequities. In public housing communities, both built and social environments are key factors that impact residents' physical activity levels. To develop and evaluate women-only physical activity programs that provide women from cultures in which physical activity in mixed-gender settings is not acceptable (e.g., Muslim women) with physical activity opportunities. We describe the use of community-based participatory research (CBPR) process and evaluation feedback from our initial research and evaluation phases, including focus groups, to shape interventions. Active community engagement in all phases of research, including cultural tailoring of interventions, and decisions about location and affordability, was critical. Implementing interventions in public housing is feasible, but requires frequent feedback from residents and correction. The use of CBPR resulted in the implementation of a successful, culturally appropriate set of physical activity interventions, specifically for Muslim Somali women. Housing authorities should consider incorporating recreational facilities on site and women-only opportunities to provide venues for physical activity.

    The National Academies' ``Rising above the Gathering Storm'' report names the improvement of K-12 science and mathematics education as its highest priority recommendation. This recommendation includes enlarging the pipeline of students preparing to study STEM subjects at university by increasing the number of students who take (and pass) advanced high school level science courses. To this end, the American Physical Society's Public Outreach department offers PhysicsQuest, a free program designed to engage middle school science students in a learning adventure. The core idea of the program is to provide a fun and exciting way for students to encounter physics, thereby eliminating some of the fear often associated with the subject and making them more likely to take high school physics courses. In the end, the students do learn some physics, but, more importantly, they have a fun experience with physics. This talk further describes the PhysicsQuest program, including feedback and results from the 2005 project, and also gives an overview of other K-12 programs offered by APS Public Outreach.

    Kaufman, Regina R; Chevan, Julia

    2011-01-01

    Studies of peer-reviewed article publication by faculty in higher education show men publish more than women. Part of the difference in publishing appears to be attributable directly to gender. Gender differences in publishing productivity have not been explored in physical therapy. The purpose of this study was to explore effects of gender on peer-reviewed publication productivity in physical therapy. This was a cross-sectional study using survey methods. A survey was administered to a random sample of 881 physical therapy faculty members; 459 responses were used for analysis. Men were more likely than women to be married, have children, hold a PhD degree, be tenured or on a tenure track, and hold the position of department chair. There was a significant difference in peer-reviewed publication rates between male and female respondents. Negative binomial regression models revealed that female gender was a negative predictor of peer-reviewed publication, accounting for between 0.51 and 0.58 fewer articles per year for women than for men over the course of a career. Reasons for the gender differences are not clear. Factors such as grant funding, laboratory resources, nature of collaborative relationships, values for different elements of the teaching/research/service triad, and ability to negotiate the academic culture were not captured by our model. The gender gap in peer-reviewed publishing productivity may have implications for individuals and the profession of physical therapy and should be subject to further exploration.

    2008-03-01

    The purpose of this research was to conduct a content analysis of physical activity advertisements in an effort to determine which advertisements were more likely to include features that may attract and maintain attention levels. Fifty-seven advertisements were collected from top circulation Canadian magazines. The advertisements ranged from publicly funded health promotion pieces to corporate sponsored advertisements using physical activity to sell a product. Advertisements were examined for textual and pictorial factors thought to increase attention allocated to advertising of this nature. Only two public health advertisements were found, and the majority of advertisements (57.9%) were from commercial advertisers using physical activity images to sell products or to encourage brand recognition. The advertisements originating with the private sector tended to possess most of the characteristics thought to attract the attention of readers. Once this attention was gained, however, most of these advertisements failed to highlight the benefits of physical activity. As a result, the positive effect of these advertisements may have been compromised. Public health advertisements were so infrequent that we could not compare their characteristics with those originating with the private sector. The characteristics with those we did find were inconsistent with those thought to attract and maintain attention levels. Results are discussed in terms of potential implications for promoting physical activity.

    To compare the extent to which Canadian public health organizations incorporated the Ottawa Charter for Health Promotion action areas in promoting physical activity and healthy eating in 2004 and 2010. Data were available from repeat censuses of all regional, provincial, and national organizations with mandates to promote physical activity [n = 134 (2004); n = 118 (2010)] or healthy eating [n = 137 (2004); n = 130 (2010)]. Eleven strategies to promote these behaviors were grouped according to the five action areas. Descriptive analyses were conducted to document the level of involvement in each action area over time. The proportion of organizations promoting physical activity and "heavily involved" in creating supportive environments increased from 51 % (2004) to 70 % (2010). The proportion also increased for reorienting health services (29 % to 39 %). The proportion of organizations promoting healthy eating and "heavily involved" in building healthy public policy increased from 47 to 53 %. Individual skill building remained stable for physical activity but declined for healthy eating. While developing personal skills remains important in promoting physical activity and healthy eating in Canada, public health organizations increased involvement in structural-level strategies.

    A strong public relations program can be of great importance to a physics department. Not only can effective PR improve the reputation of an individual department, but it can also serve the greater physics community by convincing the public that quarks, quantum dots, and nanostructures are cool. Building a solid reputation with the many constituents that a physics department serves can lead to greater media exposure, improved quality of student applicants, community and industrial partnerships, and even financial support. It isn’t difficult to create a strategic PR program, but it does take planning and commitment of resources. I will discuss the techniques and tactics of effective media, community, alumni, and internal relations, with special emphasis placed on establishing connections with media outlets, creating and publicizing outreach programs for the community, initiating a newsletter, organizing an external board of advisors, and developing an effective alumni relations program. The University of Arizona Physics Department serves as a case study, but other physics departments with similar communications programs will also be incorporated.

Methods: This is a crosssectional and qualitative study conducted in a private higher education institution, inMaceió-AL, Brazil, from June to December 2010. It comprised students from 5th and 10th period, which were allocated by convenience sampling, resulting in a final sample of 40 students with 20 students from each period. Later, each student was individually interviewedin a private, lit, air conditioned place, without time limit, being collected through a digital voice recorder the answers to the following questions: “How do you judge your knowledgeabout Public Health?” and “What is your interest in the study of Public Health?”. Collective subject discourse was used to analysis of qualitative variables. Results: Students considered their knowledge of Public Health as “limited”. Regarding their interest, the students in 5th period declared “little interest”, while the academics of the 10th period reported themselves as “very interested”. Conclusions: From the point of view of undergraduate students in Physical Therapy, their knowledge about Public Health is limited. Interest in the study of Public Health is greater among the academics closer to graduation.

    Physical inactivity has reached epidemic proportions in modern society. Abundant evidence points to a causal link between physical inactivity and increased risk for numerous noncommunicable diseases, such as some types of cancer and heart disease, as well as premature mortality. Yet, despite this overwhelming evidence, many individuals do not meet the recommended amount of physical activity required to achieve maximum health benefits. Because primary care physicians' advice is highly regarded, clinicians have the unique opportunity to play an important role in enabling patients to modify their behavior at the point of care with the goal of guiding patients to adopt and maintain an active lifestyle. In the current study, the authors evaluate pertinent literature from the fields of medicine/public health and economics/psychology to suggest a comprehensive approach to physical activity counseling at the primary care level. They first examine the public health approach to physical activity counseling, and then proceed to offer insights from behavioral economics, an emerging field that combines principles from psychology and economics. The application of key behavioral economics tools (eg, precommitment contracts, framing) to physical activity counseling in primary care is elaborated.

    2007-03-01

    The Australasian Physical & Engineering Sciences in Medicine Journal (APESM) is an avenue for the profession to report scientific work in medicine; provide a facility for the publication of current work, new research and new techniques developed or reviewed; report on professional news from elsewhere and; publish the Australasian College of Physical Scientists and Engineers in Medicine (ACPSEM) policies and protocols. The journal is a vital instrument within the ACPSEM organisation with a worldwide circulation. This review of APESM on medical physics in radiation oncology is meant to be a progress summary of work in that specialty. Even so, it has become a lengthy appraisal due to the many years involved. In considering publications related to medical physics in radiation oncology, this review has shown the progression of the College journal to an international journal. There is an increase in the number of papers contributed from Asia and other countries world wide for this discipline. Growth in the number of contributions should continue to rise. In order to provide some appreciation of where the present medical physics activity arose from, this article commences its discussion in 1959 and progresses towards the present, describing along the way, from radiation oncology papers published in APESM, the use of linear accelerators, brachytherapy, the medical physics workforce, the formation of the ACPSEM, and the more modern developments in radiotherapy such as 3-D treatment planning and IMRT.

RESULTS The prevalence of insufficient physical activity was 71.9%, and this condition was associated independently with the perception of bad or regular balance between personal and professional life (PR = 1.09; 95%CI 1.01–1.18, perception that standing time affects the work (PR = 1.16; 95%CI 1.01–1.34, low or very low perception of current ability for the physical requirements of work (PR = 1.21; 95%CI 1.08–1.35, and temporary employment contract (PR = 1.13; 95%CI 1.03–1.25. The teaching of physical education was associated with lower prevalence of insufficient physical activity (PR = 0.78; 95%CI 0.64–0.95. CONCLUSIONS The perception of adverse working conditions is associated with increased prevalence of insufficient physical activity in teachers and should be considered for the promotion of physical activity in this population.

    The aim of this paper is to assess the possible consequences of adolescent physical, emotional and sexual dating violence through a review of the literature on the topic. An electronic search of major biomedical bibliographic databases (Pubmed, ISI, PsycINFO) was used to retrieve articles providing information on the prevalence rates, risk factors, associated consequences and possible preventive measures for adolescent dating violence across different populations. Currently, there have been few longitudinal studies conducted to identify potential risk factors for entering a violent dating relationship in adolescence. Risky behaviors such as early sexual intercourse may predispose someone for victimization. Dating violence itself is also a predictor of future dating violence. Adolescent dating violence was associated with an increase in other violence-related behaviors, substance use, depression, poorer educational outcomes, posttraumatic stress, unhealthy weight control and risky sexual behavior. The association between adolescent dating violence and an increase in suicidal behavior is a major public health concern. Future research should focus on longitudinal studies so that a causal relationship between dating violence and suicidality may be better understood.

    Full Text Available This paper is a classroom ethnography. Ethnography in a research strategy that attempts to comprehensively describe a culture, in this case the culture of a physics classroom in the 12th grade of a public high school in Porto Alegre, Brazil. This study is part of a larger scope study designed to investigate the contributions of contemporary views of the nature of science to the improvement of physics teaching. It is in sense that this paper assumes an epistemological perspective. The physics teacher that was observed had conceptions partially aligned to those epistemological views, however, although our initial intention was to search for relationships between her conceptions an her teaching practices we ended up with a detailed interpretative description of the classroom reality that revealed relevant aspects to the comprehension of such a culture and to the teaching and learning process in physics. This interpretative description is what we present here.

    After the Fukushima Daiichi Nuclear Accident, the importance of bottom-up and two-way dialogue between scientists and the public has been recognized. In such dialogue, information provided must accurately match the public’s interest and ability regarding science and technology. We have started to investigate what people want to know about physics. Some were interested in energy security (a particular concern in Japan), but others were concerned about radioactivity in food and natural radiation background. The conversations revealed that physicists often give insufficient explanations of the biological effects of radiation and highlighted key points for physicists to make when talking with the public.

    Full Text Available Public parks, salient locations for engaging populations in health promoting physical activity, are especially important in high-density cities. We used the System for Observing Physical Activity in Communities (SOPARC to conduct the first-ever surveillance study of nine public parks in Hong Kong (288 observation sessions during 36 weekdays and 36 weekend days and observed 28,585 visitors in 262 diverse areas/facilities. Parks were widely used throughout the day on weekdays and weekend days and across summer and autumn; visitor rates were among the highest seen in 24 SOPARC studies. In contrast to other studies where teens and children dominated park use, most visitors (71% were adults and seniors. More males (61% than females used the parks, and they dominated areas designed for sports. Over 60% of visitors were observed engaging in moderate-to-vigorous physical activity, a rate higher than other SOPARC studies. Facilities with user fees were less accessible than non-fee areas, but they provided relatively more supervised and organized activities. Assessing parks by age, gender, and physical activity can provide useful information relative to population health. This study not only provides information useful to local administrators for planning and programming park facilities relative to physical activity, but it also provides a baseline for comparison by other high-density cities.

    In Gubbio, Italy, a l em layer of clay between extensive limestone formations marks the boundary between the Cretaceous and Tertiary Periods. This clay layer was known to have been deposited about 65 million years ago when many life forms became extinct, but the length of time associated with the deposition was not known. In an attempt to measure this time with normally deposited meteoritic material as a clock, extensive measurements of iridium abundances (and those of many other elements) were made on the Gubbio rocks. Neutron activation analysis was the principal tool used in these studies. About 50 elements are searched for in materials like the earth's crust, about 40 are detected and about 30 are measured with useful precision. We were not able to determine exactly how long the clay deposition took. Instead the laboratory studies on the chemical and physical nature of the Cretaceous-Tertiary boundary led to the theory that an asteroid collision with the earth was responsible for the extinction of many forms of life including the dinosaurs.

    The recent experimental discovery of a Higgs boson by the ATLAS and CMS collaborations at the LHC, together with the awarding of the 2013 Nobel Prize for its theoretical prediction, has presented an exceptional opportunity for public outreach regarding the goals and importance of fundamental research in physics. We discuss novel avenues for further extending this outreach in all areas. These range from tutorial papers addressing students and teachers to internet resources and presentations to unconventional, but captivating, educational materials such as musical videos and LEGO models. Interaction with active scientists can be particularly stimulating. We account how this was encouraged (by means such as badges inviting questions from the public) during Nobel week and afterwards.

    Popularity of Open Streets, temporarily opening streets to communities and closing streets to vehicles, in the US has recently surged. As of January 2016, 122 cities have hosted an Open Streets program. Even with this great expansion, the sustainability of Open Streets remains a challenge in many cities and overall Open Streets in the US differ from their successful counterparts in Central and South America. Between summer 2015 and winter 2016, we reviewed the websites and social media of the 122 identified programs and interviewed 32 unique Open Streets programs. Websites and social media were reviewed for program initiation, number of Open Streets days, length of routes, duration of program, and reported participation. Interview questions focused on barriers and facilitators of expanding Open Streets and specific questioning regarding local evaluation activities. All interviews were transcribed verbatim and analyzed with constant comparative methodology. Over three-quarters of US Open Streets programs have been initiated since 2010, with median frequency of one time per year, 4h per date, and 5000-9999 participants. Seventy-seven percent of program routes are under 5km in length. Success of programs was measured by enthusiasm, attendance, social media, survey metrics, and sustainability. Thirteen of 32 program organizers expressed interest in expanding their programs to 12 dates per year, but noted consistent barriers to expansion including funding, permitting, and branding. Though many cities now host Open Streets programs, their ability to effect public health remains limited with few program dates per year. Coordinated efforts, especially around funding, permitting, and branding may assist in expanding program dates. Copyright © 2016 Elsevier Inc. All rights reserved.

    The aim of this study was to verify the association between different types and sources of social support and physical activity among adolescents from Curitiba, Paraná State, Brazil. A school-based survey was conducted with a representative sample of adolescents from public schools (n = 1,469). Multiple regression models were used to test the association between weekly frequency and sources of social support from family and friends and weekly frequency of physical activity. Among boys, frequent company of family (PR: 2.88; 95%CI: 2.00-4.13) and friends (PR: 5.46; 95%CI: 2.33-12.78) and positive reinforcement from friends (PR: 1.81; 95%CI: 1.18-2.77) were positively associated with physical activity. Sporadic invitation by the family was negatively associated with physical activity (PR: 0.66; 95%CI: 0.46-1.14). For girls, frequent company of family (PR: 3.39; 95%CI: 1.49-7.69) and friends (PR: 4.06; 95%CI: 2.22-7.45) increased the likelihood of physical activity. Company of friends was the most important type of social support for physical activity among these adolescents.

    Multi-sectoral strategies to promote active recreation and physical activity in public spaces are crucial to building a "culture of health". However, studies on the sustainability and scalability of these strategies are limited. This paper identifies the factors related to the sustainability and scaling up of two community-based programs offering physical activity classes in public spaces in Colombia: Bogotá's Recreovía and Colombia's "Healthy Habits and Lifestyles Program-HEVS". Both programs have been sustained for more than 10years, and have benefited 1455 communities. We used a mixed-methods approach including semi-structured interviews, document review and an analysis of data regarding the programs' history, characteristics, funding, capacity building and challenges. Interviews were conducted between May-October 2015. Based on the sustainability frameworks of Shediac-Rizkallah and Bone and Scheirer, we developed categories to independently code each interview. All information was independently analyzed by four of the authors and cross-compared between programs. Findings showed that these programs underwent adaptation processes to address the challenges that threatened their continuation and growth. The primary strategies included flexibility/adaptability, investing in the working conditions and training of instructors, allocating public funds and requesting accountability, diversifying resources, having community support and champions at different levels and positions, and carrying out continuous advocacy to include physical activity in public policies. Recreovía and HEVS illustrate sustainability as an incremental, multi-level process at different levels. Lessons learned for similar initiatives include the importance of individual actions and small events, a willingness to start small while dreaming big, being flexible, and prioritizing the human factor.

    Objectives. We assessed park use in Recife, Brazil, and differences in physical activity and occupation rates in public parks with and without the Academia da Cidade Program (ACP), which provides cost-free, supervised physical activity classes. Methods. We used the System for Observing Play and Recreation in Communities (SOPARC) in 128 targeted areas in 10 park sites (5 ACP sites, 5 non-ACP sites) to obtain data on the number of users and their physical activity levels and estimated age. Each area was assessed 4 times a day for 11 days over a 4-week period. Results. A total of 32 974 people were observed during 5589 observation visits to target areas. People using ACP parks were more likely to be seen engaging in moderate-to-vigorous (64% vs 49%) and vigorous (25% vs 10%) physical activity. Relatively more participants in ACP sites than in non-ACP sites were females (45% vs 42% of park users) and older adults (14.7% vs 5.7% of park users). Conclusions. On the basis of systematic observation, ACP appears to be a useful strategy in promoting park use and physical activity among the population in Recife. PMID:20558792

    Full Text Available Introduction   Security has been one of the most fundamental needs of human society and the incidence of crime is one of the most important problems in cities. Security feeling in urban spaces is one of the crucial indicators of a good space quality which is dependent upon different aspects of socio-economic and cultural status of each society. Today social scientists try to identify the factors which impact and influence the incidence of crime in public spaces. Urban planners analyze the role of physical and environmental variables in the level of public security in urban communities. The present research attempted to study the connection between public space security and spatial and environmental factors to formulate the main planning guidelines for maintaining security and prevent crime occurrence in the city of Babolsar.     Materials and Methods   The city of Babolsar is located in the southern part of the Caspian Sea and is one of the important tourist destinations in Mazandaran province. The methodology of the research is based on descriptive and analytical approaches and the required data and information were collected by conducting a field work to complete the research questionnaire. The reliability of the questionnaire was justified by Cronbach Alfa coefficient (0.792 and the validity of the questions were confirmed by the help of several experts. The statistical society of the present research includes 14422 households of Babolsar city and the sample was selected via Cochran formula (350 household heads. In general, nine main components and 35 indicators were used to measure the physical components of public spaces. Also three components and 22 indicators were applied for investigating the social security in this research. The data was processed vial SPSS and different statistical tests such as Pearson regression and T test were used to determine the possible relationships among the variables.     Discussion of Results and

    Background and Objective Professional meetings, such as the American Physical Therapy Association's (APTA's) Combined Sections Meeting (CSM), provide forums for sharing information relevant to physical therapy. An indicator of whether therapists fully disseminate their work is the number of full-text peer-reviewed publications that result. The purposes of this study were: (1) to determine the full-text publication rate of work presented in abstract form at CSM and (2) to investigate factors influencing this rate. Methods A systematic search was undertaken to locate full-text publications of work presented in abstract form within the Orthopaedic and Sports Physical Therapy sections at CSM between 2000 and 2004. Eligible publications were published within 5 years following abstract presentation. The influences of APTA section, year of abstract presentation, institution of origin, study design, sample size, study significance, reporting of a funding source, and presentation type on full-text publication rate were assessed. Characteristics of full-text publications were explored. Results Work presented in 1 out of 4 abstracts (25.4%) progressed to full-text publication. Odds of full-text publication increased if the abstract originated from a doctorate-granting or “other” institution, reported findings of an experimental study, reported a statistically significant finding, included a larger sample size, disclosed a funding source, or was presented as a platform presentation. More than one third (37.8%) of full-text publications were published in the Journal of Orthopaedic and Sports Physical Therapy or Physical Therapy, and 4 out of 10 full-text publications (39.2%) contained at least one major change from information presented in abstract form. Conclusions The full-text publication rate for information presented in abstract form within the Orthopaedic and Sports Physical Therapy sections at CSM is low relative to comparative disciplines. Caution should be

    Physical activity (PA) is considered a cornerstone in weight control and public health guidelines recommend regular participation to prevent gains in adiposity. It may therefore come as a surprise that the cumulative evidence from observational studies to support this is not strong. A weakness...... of many published observational studies on this topic has been a reliance on a single baseline assessment of PA. Using only the baseline information on PA in a prospective study cause misclassification because of participants often change activity level during follow-up. In turn this causes regression...

    2015-09-01

    Full Text Available In Participation in physical education is considered to be a fundamental right of pupils all over the world. In Hungary, where the rich elite sports traditions of the country are paralleled by the population’s moderate physical activity, the challenge posed by non-communicable diseases and growing obesity figures among youth was addressed by the introduction of daily P.E. in public education starting in the 2012/13 academic year. The objective of the present paper is to discuss, based on empirical research, the intended and unintended consequences of this measure in an educational and social context using the qualitative analysis of the views of key stakeholders and the quantitative analysis of statistical data on the infrastructural and personal conditions of P.E. The results indicate that neither before nor after the enforcement of the Act on Public Education were the infrastructural and personal conditions of daily P.E. created and, in addition to the intended consequences, a number of unintended consequences have also been encountered by various stakeholders. The study can also be regarded as an attempt to reveal these dysfunctions in order to contribute to positive changes in the area.

    To analyze factors associated with physical activity and the mean time spent in some sedentary activities among school-aged children. A cross-sectional study was carried out in a random sample of 592 schoolchildren aged nine to 16 years in 2005, in São Luís, Northern Brazil. Data were collected by means of a 24-Hour Physical Activity Recall Questionnaire, concerning demographic and socioeconomic variables, physical activities practiced and time spent in certain sedentary activities. Physical activities were classified according to their metabolic equivalents (MET), and a physical activity index was estimated for each child. Sedentary lifestyle was estimated based on time spent watching television, playing videogames and on the computer/internet. Chi square test was used to compare proportions. Linear regression analysis was used to establish associations. Estimates were adjusted for the effect of the sampling design. The mean of the physical activity index was 605.73 MET-min/day (SD = 509.45). School children that were male (coefficient=134.57; 95%CI 50.77; 218.37), from public schools (coefficient.= 94.08; 95%CI 12.54; 175.62 and in the 5th to 7th grade (coefficient.=95.01; 95%CI 8.10;181.92 presented higher indices than females, children from private schools and in the 8th to the 9th grade (p<0.05). On average, students spent 2.66 hours/day in sedentary activities. Time spent in sedentary activities was significantly lower for children aged nine to 11 years (coefficient.= -0.49 hr/day; 95%CI -0.88; -0.10) and in lower socioeconomic classes (coefficient.=-0.87; 95%CI -1.45;-0.30). Domestic chores (59.43%) and walking to school (58.43%) were the most common physical activities. Being female, in private schools and in the 8th to 9th grade were factors associated with lower levels of physical activity. Younger schoolchildren and those from low economic classes spent less time engaged in sedentary activities.

    National, epidemiological data that provide lifetime rates of psychological, physical, and sexual adolescent data abuse (ADA) perpetration and victimization within the same sample of youth are lacking. To address this gap, data from 1058 randomly selected U.S. youth, 14-21 years old, surveyed online in 2011 and/or 2012, were weighted to be nationally representative and analyzed. In addition to reporting prevalence rates, we also examined the overlap of the six types of ADA queried. Results suggested that ADA was commonly reported by both male and female youth. Half (51 %) of female youth and 43 % of male youth reported victimization of at least one of the three types of ADA. Half (50 %) of female youth and 35 % of male youth reported at least one type of ADA perpetration. More male youth reported sexual ADA perpetration than female youth. More female youth reported perpetration of psychological and physical ADA and more reported psychological victimization than male youth. Rates were similar across race and ethnicity, but increased with age. This increase may have been because older youth spent longer time in relationships than younger youth, or perhaps because older youth were developmentally more likely than younger youth to be in abusive relationships. Many youth reported being both perpetrators and victims and/or involved in multiple forms of ADA across their dating history. Together, these findings suggested that interventions should acknowledge that youth may play multiple roles in abusive dyads. Understanding the overlap among ADA within the same as well as across multiple relationships will be invaluable to future interventions aiming to disrupt and prevent ADA.

    Physical activity is associated with health. The aim of this study was (a) to access if Portuguese university students meet the public health recommendations for physical activity and (b) the effect of gender and day of the week on daily PA levels of university students. This observational cross-sectional study involved 126 (73 women) healthy Portuguese university students aged 18-23 years old. Participants wore the ActiGraph wGT3X-BT accelerometer for seven consecutive days. Number of steps, time spent sedentary and in light, moderate and vigorous physical activity were recorded. The two-way MANOVA revealed that gender (p-value = 0.001; η2 = 0.038; minimum effect) and day of the week (p-value = 0.001; η2 = 0.174; minimum effect) had significant main effects on the physical activity variables. It was shown that during weekdays, male students walked more steps (65.14%), spent less time sedentary (6.77%) and in light activities (3.11%) and spent more time in moderate (136.67%) and vigorous activity (171.29%) in comparison with weekend days (p students walked more steps (51.18%) and spent more time in moderate (125.70%) and vigorous (124.16%) activities during weekdays than in weekend days (p students did not achieve the recommended 10,000 steps/day on average during weekdays and weekend days. Only male students achieved this recommendation during weekdays. In summary, this study showed a high incidence of sedentary time in university students, mainly on weekend days. New strategies must be adopted to promote physical activity in this population, focusing on the change of sedentary behaviour.

    The concepts of quality management have increasingly been introduced into the health sector. Methods to measure satisfaction and quality are examples of this trend. This study aimed to identify the level of customer satisfaction in a physical therapy department involved in the public area and to analyze the key variables that impact the usersâ€(tm) perceived quality. A cross-sectional observational study was conducted, and 95 patients from the physical therapy department of the Hospital Universitário Gaffrée e Guinle - Universidade Federal do Estado do Rio de Janeiro (HUGG/UNIRIO) - Rio de Janeiro, Brazil, were evaluated by the SERVQUAL questionnaire. A brief questionnaire to identify the sociocultural profile of the patients was also performed. Patients from this health service presented a satisfied status with the treatment, and the population final average value in the questionnaire was 0.057 (a positive value indicates satisfaction). There was an influence of the educational level on the satisfaction status (χ²=17,149; p=0.002). A correlation was found between satisfaction and the dimensions of tangibility (rho=0.56, p=0.05) and empathy (rho=0.46, p=0.01) for the Unsatisfied group. Among the Satisfied group, the dimension that was correlated with the final value of the SERVQUAL was responsiveness (rho=0.44, p=0.01). The final values of the GGUH physical therapy department showed that patients can be satisfied even in a public health service. Satisfaction measures must have a multidimensional approach, and we found that people with more years of study showed lower values of satisfaction.

    The purpose of this study was to examine the intensity levels of PA opportunities offered in public school classrooms. Schools (N = 101) in school districts (N = 25) reported PA opportunities offered in classrooms using an online data collection tool over a two-year period (2014-2016). Using a randomized sampling technique, 20-30% of teachers in each school were selected each week to report PA in their classroom. These responses resulted in N = 18,210 usable responses. A researcher determined the intensity of PA opportunities using the 2011 Compendium of Physical Activities as a guideline; two additional researchers confirmed the coded categories. A descriptive analysis of PA opportunities was conducted to describe the proportion of opportunities whose intensity levels were light (LPA), moderate (MPA), vigorous (VPA), sedentary (SED), and those of unknown intensity. Chi-square analyses were utilized to examine differences between proportions of intensity levels offered by semester. Kruskal-Wallace tests were utilized to examine differences in proportion of physical activity opportunity intensity offered by grade level. Most PA opportunities were MPA (58.7%), followed by VPA (17.6%) and LPA (11.5%). Few responses were SED (0.5%), and 11.6% were of indeterminate intensity. A greater proportion of more physically intense activities reported during the fall versus spring semesters (p classrooms; a previously underexplored construct of school-based PA.

  8. Developing legally defensible physiological employment standards for prominent physically demanding public safety occupations: a Canadian perspective.

    2013-10-01

    Canadian court decisions and human rights legislation impose strict legal criteria for developing applicant and incumbent physiological employment standards to qualify as a bona fide occupational requirement. These legal criteria compel researchers and employers to ensure that the standards are criterion-based and validly linked to the critical life threatening physically demanding tasks of the occupation, and this has led to the establishment of a systematic research process template to ensure this connection. Validation of job-related physiological employment standards is achieved using both construct and content procedures and reliability is established via test-retest procedures. The 1999 Supreme Court of Canada Meiorin Decision also obliges employers to demonstrate that it is impossible to accommodate an individual applicant or employee who is adversely impacted by lowering the physiological employment standards without imposing undue hardship on the employer. Recent evidence has demonstrated convincingly that familiarization opportunities, motivational feedback/coaching during test performance, and participation in a 6-week job-specific physical fitness training program can overcome the adverse impact of a physiological employment standards on a sub-group of participants, thereby providing "de facto" accommodation. In this article, the authors review the physiological employment standards for prominent Canadian physically demanding public safety occupations; police, correctional officers, nuclear emergency personnel, structural fire fighters, and wildland fire fighters, to illustrate the steps, challenges, and solutions involved in developing and implementing physiological employment standards designed to meet the requirements to qualify as a bona fide occupational requirement.

    Full Text Available School education as well as physical education (PE and society as a whole, are currently living a crisis process. Thereby, in this study, we analyze how PE teachers are developing pedagogical intervention in public schools. For this purpose, we developed a qualitative study and to achieve data we used semi-structured interviews with ten PE teachers. Data show that in the studied context, PE at schools has yet been developed as an activity and not as a curricular component; the sports content constitutes as basically the only working subject; and there’s a lack of an education planning. Thus, we conclude that scholastic PE, in the analyzed context, lies in teaching abandonment.

    Although the scientific community increasingly recognizes that its communication with the public may shape civic engagement with science, few studies have characterized how this communication occurs online. Social media plays a growing role in this engagement, yet it is not known if or how different platforms support different types of engagement. This study sets out to explore how users engage with science communication items on different platforms of social media, and what are the characteristics of the items that tend to attract large numbers of user interactions. Here, user interactions with almost identical items on five of CERN's social media platforms were quantitatively compared over an eight-week period, including likes, comments, shares, click-throughs, and time spent on CERN's site. The most popular items were qualitatively analyzed for content features. Findings indicate that as audience size of a social media platform grows, the total rate of engagement with content tends to grow as well. However, per user, engagement tends to decline with audience size. Across all platforms, similar topics tend to consistently receive high engagement. In particular, awe-inspiring imagery tends to frequently attract high engagement across platforms, independent of newsworthiness. To our knowledge, this study provides the first cross-platform characterization of public engagement with science on social media. Findings, although focused on particle physics, have a multidisciplinary nature; they may serve to benchmark social media analytics for assessing science communication activities in various domains. Evidence-based suggestions for practitioners are also offered.

    The months that have passed since the last CMS Bulletin have been a very busy and exciting time for CMS physics. We have gone from observing the very first 8TeV collisions produced by the LHC to collecting a dataset of the collisions that already exceeds that recorded in all of 2011. All in just a few months! Meanwhile, the analysis of the 2011 dataset and publication of the subsequent results has continued. These results come from all the PAGs in CMS, including searches for the Higgs boson and other new phenomena, that have set the most stringent limits on an ever increasing number of models of physics beyond the Standard Model including dark matter, Supersymmetry, and TeV-scale gravity scenarios, top-quark physics where CMS has overtaken the Tevatron in the precision of some measurements, and bottom-quark physics where CMS made its first discovery of a new particle, the Ξ*0b baryon (candidate event pictured below).

    Full Text Available Most previous studies examining physical activity in Public Open Spaces (POS focused solely on the physical environment. However, according to socio-ecological models the social environment is important as well. The aim of this study was to determine which social and physical environmental factors affect adolescents' visitation and physical activity in POS in low-income neighbourhoods. Since current knowledge on this topic is limited, especially in Europe, qualitative walk-along interviews were used to obtain detailed and context-specific information. Participants (n = 30, aged 12-16 years, 64% boys were recruited in POS in low-income neighbourhoods in Brussels, Ghent and Antwerp (Belgium. Participants were interviewed while walking in the POS with the interviewer. Using this method, the interviewer could observe and ask questions while the participant was actually experiencing the environment. All audio-recorded interviews were transcribed and analysed using Nvivo 10 software and thematic analysis was used to derive categories and subcategories using a grounded theory approach. The most important subcategories that were supportive of visiting POS and performing physical activity in POS were; accessibility by foot/bicycle/public transport, located close to home/school, presence of (active friends and family, cleanliness of the POS and features, availability of sport and play facilities, large open spaces and beautiful sceneries. The most important subcategories that were unsupportive of visiting POS and physical activity in POS were; presence of undesirable users (drug users, gangs and homeless people, the behaviour of other users and the cleanliness of the POS and features. Social factors appeared often more influential than physical factors, however, it was the combination of social and physical factors that affected adolescents' behaviour in POS.

Planning for the upcoming higher luminosity/higher energy (8 TeV) operation of the LHC and relatively early Rencontres de Moriond are the high-priority activities for the group at the moment. To be ready for the coming 8-TeV data, CMS has made a concerted effort to perform and publish analyses on the 5 fb−1 dataset recorded in 2011. This has resulted in the submission of 16 papers already, including nine on the search for the Higgs boson. In addition, a number of preliminary results on the 2011 dataset have been released to the public. The Exotica and SUSY groups approved several searches for new physics in January, such as searches for W′ and exotic highly ionising particles. These were highlighted at a CERN seminar given on 24th  January. Many more analyses, from all the PAGs, including the newly formed SMP (Standard Model Physics) and FSQ (Forward and Small-x QCD), were approved in February. The ...

  18. Public and Private Physical Affection Differences between Same-Sex and Different-Sex Couples: The Role of Perceived Marginalization

    2011-12-01

    Full Text Available Despite its connection with relationship satisfaction, research on physical affection is scarce and fails to disentangle private and public displays of affection. It is important to examine both types if marginalized couples are less comfortable displaying affection publicly. The present study examined whether same-sex couples display less public (but not private physical affection than different-sex couples due to stronger feelings of relationship marginalization. It also examined how public/private affection and marginalization relate to relationship satisfaction. Women in committed same-sex and different-sex relationships completed surveys of public affection, private affection, marginalization, and relationship satisfaction online. As predicted, women in same-sex relationships displayed less public affection than those in different-sex relationships, an effect mediated by general societal marginalization. Both private and public affection predicted higher relationship satisfaction, whereas feelings of marginalization by friends/family predicted lower relationship satisfaction. We discuss implications for relationship counseling and propose new ways of looking at marginalization.

    By the onset of the Second World War, the British scientific periodical Nature--specifically, Nature's 'Letters to the editor' column--had become a major publication venue for scientists who wished to publish short communications about their latest experimental findings. This paper argues that the Nobel Prize-winning physicist Ernest Rutherford was instrumental in establishing this use of the 'Letters to the editor' column in the early twentieth century. Rutherford's contributions set Nature apart from its fellow scientific weeklies in Britain and helped construct a defining feature of Nature's influence in the twentieth century. Rutherford's participation in the journal influenced his students and colleagues in the field of radioactivity physics and drew physicists like the German Otto Hahn and the American Bertram Borden Boltwood to submit their work to Nature as well, and Nature came to play a major role in spreading news of the latest research in the science of radioactivity. Rutherford and his colleagues established a pattern of submissions to the 'Letters to the editor' that would eventually be adopted by scientists from diverse fields and from laboratories around the world.

    Full Text Available Plots and figures play an important role in the process of understanding a scientificpublication, providing overviews of large amounts of data or ideas that are difficult to in-tuitively present using only the text. State of art in digital libraries, serving as gatewaysto knowledge encoded in scholarly writings, does not take full advantage of the graphicalcontent of documents. Enabling machines to automatically unlock the meaning of scien-tific illustrations would allow immense improvements in the way scientists work and theknowledge is being processed.    In this paper we present a novel solution for the initial problem of processing graphicalcontent, obtaining figures from scholarly publications stored in PDF format. Our methodrelies on vector properties of documents and as such, does not introduce additional errors,characteristic for methods based on raster image processing. Emphasis has been placed oncorrectly processing documents in High Energy Physics. The described approach makesdistinction between different classes of objects appearing in PDF documents and usesspatial clustering techniques to group objects into larger logical entities. A number ofheuristics allow the rejection of incorrect figure candidates and the extraction of differenttypes of metadata.

    Teen dating violence (TDV) is unstable across dating relationships, suggesting that characteristics of the relationship could be related to TDV. Few empirical studies have examined these links. This study examined associations between relationship characteristics and TDV perpetration among teens and sex differences in those associations. Relationship characteristics examined include tactics used to manipulate partners; ways of responding to relationship problems; relationship duration; exclusivity of the relationship; age difference between partners; and history of sexual intercourse with partner. Data were drawn from 667 teens in a current relationship (62.5% female and 81.4% white) enrolled in the 11(th) or 12(th) grade in 14 public schools in a rural US state. Bivariate and multivariable regression analyses examined proposed associations. 30.1% and 8.2% of teens reported controlling and physical TDV perpetration, respectively. In multivariable models, frequent use manipulation tactics increased risk for controlling or physical TDV perpetration. Teens dating a partner two or more years younger were at significantly increased risk for both controlling and physical perpetration. A significant interaction emerged between sex and exit/neglect accommodation for physical TDV. Characteristics of a current dating relationship play an important role in determining risk for controlling and physical TDV perpetration.

    Physical samples are important observational units in Earth and Space sciences. Samples and their derived data play vital role in scientific validation and reproducibility. Systematic practices and technical solutions are required to curate and publish samples and their data on the Web. Persistent identifiers ensure unambiguous identification, and enable linkage and citation of samples and associated data sets. The International Geo Sample Number (IGSN) is a persistent and globally unique identifier for physical samples and sample collections. IGSNs are allocated to clients (e.g., laboratories, projects, individual users) through agents. Agents are institutions that represent the IGSN e.V., the IGSN Implementation Organization. For example, CSIRO, Geoscience Australia and Curtin University are IGSN allocating agents in Australia. Clients register IGSNs for samples through the respective agent's registration services. The Discovery research program of CSIRO is conducting research in the prolific metallogenic provinces of the Capricorn Orogen - a regional study aimed to define distal footprints of covered ore systems. In CSIRO, the Capricorn Distal Footprints (CAPDF) project is one of the early adopters of the IGSN in its sample curation. The project involves collection of various samples, including water, rock, sediment, vegetation and regolith, which are collected by different researchers. The application of IGSN requires not only the supporting infrastructure and tools (e.g., user interface, service, metadata model) but also systematic workflows to cater different users, i.e., practices of laboratories or individual researchers. We present the application of the IGSN in the context of the CAPDF project as a sample inventory management system, samples identification in publications and sample discovery through a web portal. We describe workflows that demonstrate IGSN integration into existing sample curation practices and highlight challenges and benefits of such a

    Symptoms of psychological distress may be one pathway through which child maltreatment and witnessing violence in the home relate to dating violence victimization. This study examined whether psychological distress in mid-adolescence mediated the link between child maltreatment and witnessing violence in early adolescence and dating violence victimization in young adulthood. The sample included female participants (N = 532) from the National Survey of Child and Adolescent Well Being who were 18 years or older in the fifth and final wave of data collection. At the time of entry into the study, participants were 12.81 (SD = 1.23) years old. Sixteen percent of participants identified as Hispanic; 53 % identified their race as White, 33 % as Black, and 11 % as American Indian. Results showed that psychological distress may play a causal role in the relationship of violence in the home to dating violence victimization. Interventions targeting psychological distress, particularly in samples at risk for child maltreatment, may reduce the risk of dating violence victimization.

    Background: Despite improvements in information technology (IT) infrastructure in public health, there is still much that can be done to improve the adoption of IT in state and local health departments, by better understanding the impact of governance and control structures of physical infrastructure. Objective: To report out the current status of the physical infrastructure control of local health departments (LHDs) and to determine whether there is a significant association between an LHD's governance status and control of the physical infrastructure components. Design: Data came from the 2015 Informatics Capacity and Needs Assessment Survey, conducted by Georgia Southern University in collaboration with the National Association of County and City Health Officials. Participants: A total of 324 LHDs from all 50 states completed the survey (response rate: 50%). Main Outcome Measure(s): Outcome measures included control of LHD physical infrastructure components. Predictors of interest included LHD governance category. Results: The majority of the control of the physical infrastructure components in LHDs resides in external entities. The type of governance structure of the LHD is significantly associated with the control of infrastructure. Conclusions: Additional research is needed to determine best practices in IT governance and control of physical infrastructure for public health. PMID:27684612

    The objective of this article is to explain the process of the development of and to assess the Mexican food-based dietary and physical activity guidelines (FBDGs). The FBDGs were developed by an intersectoral and interdisciplinary committee of 11 national experts with input from 11 external advisors. The sectors represented were research and academic institutions, the Ministry of Health, and a nongovernmental organization. The evidence-based process included the following: literature reviews of local, national, and international evidence; review of dietary patterns of the Mexican population; key national and international recommendations; and review of FBDGs and visual icons from other countries. The guidelines' report follows the life-course socioecological model rooted in a deep understanding of the epidemiology and underlying causes of malnutrition in Mexico. The guidelines are summarized in 10 pretested main recommendations that include, and go beyond, simply promoting the consumption of a healthy and varied diet that includes fresh fruits, vegetables, legumes, and whole grains and staying within caloric needs and staying active. The guidelines strongly emphasize healthy cooking habits, enjoyable meals with family and friends, drinking water, and avoiding the consumption of sweetened beverages, grain-based desserts, and highly processed foods. Detailed guidelines specific to different groups (on the basis of age and physiologic status) are also included. An innovative aspect of the Mexican FBDGs is the inclusion of dietary guidance of children Mexican FBDGs in the context of addressing the national obesity epidemic deserves to be initiated and formally assessed through the lens of evidence-based, public nutrition complex adaptive systems.

    2011-10-01

    Full Text Available This paper describes a teaching experiment designed to examine the learning (i.e., retention of content and conceptual development that takes place when public scientific web lectures delivered by scientists are utilized to present advanced ideas in physics to students with a high school background in physics. The students watched an exemplary public physics web lecture that was followed by a collaborative generic activity session. The collaborative session involved a guided critical reconstruction of the main arguments in the lecture, and a processing of the key analogical explanations. Then the students watched another exemplary web lecture on a different topic. The participants (N=14 were divided into two groups differing only in the order in which the lectures were presented. The students’ discussions during the activities show that they were able to reason and demonstrate conceptual progress, although the physics ideas in the lectures were far beyond their level in physics. The discussions during the collaborative session contributed significantly to the students’ understanding. We illustrate this point through an analysis of one of these discussions between two students on an analogical explanation of the Aharonov-Bohm effect that was presented in one of the lectures. The results from the tests that were administered to the participants several times during the intervention further support this contention.

  14. Promoting the Swedish method of physical education throughout France for the benefit of public health (1868-1954).

    2013-03-01

    This article examines the cultural and public health challenges associated with the dissemination of the Swedish approach and methods of physical education throughout France and illustrates the two main methods of influence, both direct through research and study visits and indirect through the creation of an international network entitled the International Federation of Physical Education. More particularly, it studies the roles of Philippe Tissié in 1898 and Pierre Seurin in 1946, and shows how these two major players of French physical education contributed actively to strengthening Swedish influence throughout France. It also highlights their equally essential role in the successful implementation of a pro-Swedish network in France, intended to serve their public health aims. This analysis forms part of the geopolitical and socio-cultural history of foreign physical education models, whose exemplarity was mainly dependent on Franco-Swedish relations and the models' social representations. Using archives from the French Physical Education League, travel logs and the Revue des jeux scolaires et d'hygiène sociale (Journal for School Games and Social Hygiene), it has been shown why the myth of the Swedish Eldorado contributed to creating, in France, "a work of art and of science that was, at the same time, both national and practical."

    The paper will comment on a few issues of particular relevance to Australasia. Thermoluminescent (TL) methods applied to open sites have been demonstrated to be effective. A particularly good example of this is to be found in the South East of South Australia, where a sequence of low ranges runs roughly parallel with the coast. They represent relict sand dunes left behind, on a slowly rising land surface by successive interglacial incursions of the sea at roughly 120 ka intervals. Comparison with ages established on independent geological grounds allows a test of quartz TL and IRSL ages that is believable back to 500 ka. Older than this, we do not yet understand the physics of the quartz well enough to go unequivocally forward (backward?). Similar results are emerging elsewhere. With dating limits being pushed ever further back, the time variation of the environmental radiation giving rise to the stored luminescent energy needs to be addressed. Particularly at wet sites, radioactive disequilibrium must be considered. In any case, a time profile of the radiation dose rate needs to be determined.In dating a given site or sites the value of ages obtained by any dating method,including C-14, is enhanced by parallel measurements with an different method.

    The World Health Organization has declared that violence is a global public health problem. The prevalence of violence exposure among adults with intellectual and unspecific disabilities has been demonstrated in several studies, whereas only a few articles on people with sensory disabilities have been published. The aim of this study was to investigate the prevalence and risk for exposure to physical violence, psychological offence, or threats of violence in people with physical and/or sensory disabilities, compared with people with no such disabilities, controlling for socioeconomic data. Data from a public health survey were analyzed. A nationally representative sample of women and men aged 16 to 84 years had answered a questionnaire. In the present study, the whole sample, comprised of 25,461 women and 21,545 men, was used. Women with auditory disabilities were generally more often violence exposed than non-disabled women, whereas men with physical disabilities were more often violence exposed than non-impaired men. Some age groups among both women and men with visual disabilities had higher prevalence rates than women and men without disabilities. The adjusted odds ratios (ORs) were significantly higher among the auditory impairment group for exposure to physical (OR = 1.4, confidence interval [CI] = [1.1, 1.9]) and psychological (OR = 1.4, CI = [1.1, 1.8]) violence among women. Men with physical disabilities had raised odds ratios for physical violence (OR = 1.7, CI = [1.2, 2.4]) and psychological violence (OR = 1.4, CI = [1.0, 2.0]) compared with the non-disabled group. Both men and women with a physical or sensory disability showed higher odds of being exposed to violence than men and women without a disability. The results indicated that socioeconomic situation, smoking, and hazardous drinking strengthened the association between impairment and violence.

    Dating violence is an important public health concern and is considered to be a form of school violence. While digital technologies have enabled perpetrators of dating violence to target their victims online (cyber dating abuse), little is known about how this form of perpetration relates to specific adolescent risk behaviors. This brief research report focuses on the associations between substance use, sexual behaviors, deviant behaviors, self-reported health, and cyber dating abuse perpetration. Participants included 705 ethnically diverse adolescents ( n = 408; 57.9% female) in Southeast Texas. Having had sexual intercourse or using alcohol or drugs before having sex was significantly linked with cyber dating abuse perpetration, as was poor physical health, and substance use. Consistent with limited research, we found a link between cyber dating abuse and engagement in bullying behaviors. The discussion section includes suggestions for school nurse practice and further research.

    Full Text Available Abstract Background As concern about youth obesity continues to mount, there is increasing consideration of widespread policy changes to support improved nutritional and enhanced physical activity offerings in schools. A critical element in the success of such programs may be to involve students as spokespeople for the program. Making such a public commitment to healthy lifestyle program targets (improved nutrition and enhanced physical activity may potentiate healthy behavior changes among such students and provide a model for their peers. This paper examines whether student's "public commitment"--voluntary participation as a peer communicator or in student-generated media opportunities--in a school-based intervention to prevent diabetes and reduce obesity predicted improved study outcomes including reduced obesity and improved health behaviors. Methods Secondary analysis of data from a 3-year randomized controlled trial conducted in 42 middle schools examining the impact of a multi-component school-based program on body mass index (BMI and student health behaviors. A total of 4603 students were assessed at the beginning of sixth grade and the end of eighth grade. Process evaluation data were collected throughout the course of the intervention. All analyses were adjusted for students' baseline values. For this paper, the students in the schools randomized to receive the intervention were further divided into two groups: those who participated in public commitment activities and those who did not. Students from comparable schools randomized to the assessment condition constituted the control group. Results We found a lower percentage of obesity (greater than or equal to the 95th percentile for BMI at the end of the study among the group participating in public commitment activities compared to the control group (21.5% vs. 26.6%, p = 0.02. The difference in obesity rates at the end of the study was even greater among the subgroup of students who

    2011-11-01

    Full Text Available Abstract Background It is rare that decisions about investing in public health interventions in a city, town or other location can be informed by research generated in that specific place. It is therefore necessary to base decisions on evidence generated elsewhere and to make inferences about the extent to which this evidence is generalisable to the place of interest. In this paper we discuss the issues involved in making such inferences, using physical activity as an example. We discuss the ways in which elements of the structural, physical, social and/or cultural environment (environmental factors [EFs] can shape physical activity (PA and also how EFs may influence the effectiveness of interventions that aim to promote PA. We then highlight the ways in which EFs may impact on the generalisability of different types of evidence. Discussion We present a framework for thinking about the influence of EFs when assessing the generalisability of evidence from the location in which the evidence was generated (place A to the location to which the evidence is to be applied (place B. The framework relates to similarities and differences between place A and place B with respect to: a the distributions of EFs; b the causal pathways through which EFs or interventions are thought to exert their effect on PA and c the ways in which EFs interact with each other. We suggest, using examples, how this scheme can be used by public health professionals who are designing, executing, reporting and synthesising research on PA; or designing/implementing interventions. Summary Our analysis and scheme, although developed for physical activity, may potentially be adapted and applied to other evidence and interventions which are likely to be sensitive to influence by elements of the structural, physical, social and/or cultural environment such as the epidemiology of obesity and healthy weight promotion.

    The objective of this study was to investigate the effect of regular physical activity on the haemodynamic response to public speaking and to evaluate the long-term effect of exercise on development of hypertension. We assessed 75 sedentary and 44 active participants screened for stage 1 hypertension with consistent activity habits and 63 normotensive individuals as control. The blood pressure (BP) response to public speaking was assessed with beat-to-beat noninvasive recording. Definition of incident hypertension was based either on clinic or 24-h BP measurement. The BP response to public speaking was greater in the hypertensive than the normotensive participants (P=0.018/0.009). Among the former, sedentary participants showed increased BP reactivity to the speech test (45.2+/-22.6/22.2+/-11.5mmHg, Ppublic speaking into the Cox model influenced the strength of the association only marginally [hazard ratio=0.55 (95% CI 0.30-0.97) and hazard ratio=0.59 (95% CI 0.36-0.99), respectively]. Regular physical activity attenuates the BP reaction to psychosocial stressors. However, this mechanism seems to be only partially responsible for the long-term effect of exercise on BP.

    Physical activity is an important component of strategies for health promotion and prevention of noncommunicable diseases. It is also associated with decreased risk for cardiovascular disease in overweight and obese adults and children. This article addresses the initial description of a physical activity intervention for children attending public elementary schools in Mexico. The objective was to develop a replicable model based on a strategic public, private, academic, and social partnership that would have a short-term impact on the metabolic health of children and be useful for building effective public policy. Forty-nine schools (20 000 students) participated, and 5 schools were selected for evaluation. The intervention included a 30-minute supervised middle-effort interchangeable routine, 5 days a week for a complete school year, adapted for different school conditions and students of different ages. Evaluation included anthropometric measurements and biochemical markers. Actual prevalence of combined overweight and obesity in these children was 31.9%. The intervention was successfully implemented in all schools. No change in body mass index, waist circumference, or other anthropometric indicators was found. However, changes in biochemical markers showed a significant decrease in blood glucose, total cholesterol, and cholesterol-low-density lipoproteins, reflecting a positive effect on cardiovascular health indicators.

    Full Text Available The objective of this study was to investigate the dietary habits and physical activity of adolescents aged 16 to 17 years from public schools in Florianópolis, SC. The sample consisted of 720 students, including 252 boys and 468 girls. Two questionnaires were applied, which were sent to the students and their parents. Descriptive statistics mean and standard deviation was used for data analysis and differences between groups were analyzed by the chi-square test, with a 95% confidence interval. Among the adolescents studied, 69.1% participated regularly in physical education at school, whereas 59.6% did not perform any physical activity outside of school. Among the adolescents who performed organized physical activity outside of school (40.4%, 55.9% were boys and 35.1% were girls, and most of them (61.6% performed physical activity three times per week. With respect to physical activity level, most students (48.3% were classified as active at the intermediate level and 30.6% were classified as active, with a higher proportion of boys (43.6% than girls (23.5%. In addition, 54.5% of the students watched TV for more than 3 h/day. Regarding dietary habits, 55.4% of the adolescents presented a healthy diet according to the parameters used in this study, with a higher proportion of boys (61.5% than girls (51.9%. Boys consumed more milk than girls who, in turn, reported a higher consumption of candy compared to boys. In general, most of the adolescents presented positive health behaviors such as good physical activity and dietary habits.

    There have been three physics meetings since the last CMS week: “physics days” on March 27-29, the Physics/ Trigger week on April 23-27 and the most recent physics days on May 22-24. The main purpose of the March physics days was to finalize the list of “2007 analyses”, i.e. the few topics that the physics groups will concentrate on for the rest of this calendar year. The idea is to carry out a full physics exercise, with CMSSW, for select physics channels which test key features of the physics objects, or represent potential “day 1” physics topics that need to be addressed in advance. The list of these analyses was indeed completed and presented in the plenary meetings. As always, a significant amount of time was also spent in reviewing the status of the physics objects (reconstruction) as well as their usage in the High-Level Trigger (HLT). The major event of the past three months was the first “Physics/Trigger week” in Apri...

    The alluvial-fluvial drainage system in the Wadi Araba, southern Jordan, incised into Cambrian clastic sedimentary and felsic igneous rocks giving rise to a disseminated Cu-(Mn) mineralization of diagenetic and epigenetic origin along the southern branch of the Dead Sea Transform Fault (=DSTF). During the Late Pleistocene and Holocene, the primary Cu sulfides were replaced by secondary minerals giving rise to hypogene to supergene encrustations, bearing Cu silicates, Cu carbonates, Cu oxychlorides and cupriferous vanadates. They occur in fissures, coat walls and developed even-rim/meniscus and blocky cements in the arenites near the surface. The first generation cement has been interpreted in terms of freshwater vadose hydraulic conditions, while the second-generation blocky cement of chrysocolla and malachite evolved as late cement. The Cu-Si-C fluid system within the Wadi Araba drainage system is the on-shore or subaerial facies of a regressive lacustrine regime called the "Lake Lisan Stage", a precursor of the present-day Dead Sea. Radiocarbon dating (younger than 27,740 ± 1,570 years), oxygen-isotope-based temperature determination (hot brine-related mineralization at 60-80 °C, climate-driven mineralization at 25-30 °C) and thermodynamical calculations let to the subdivision of this secondary Cu mineralization into four stages, whose chemical and mineralogical composition was controlled by the variation of the anion complexes of silica and carbonate and the chlorine contents. The acidity of the pore water positively correlates with the degree of oxidation. The highest aridity and most intensive evaporation deduced from the thermodynamical calculations were achieved during stage 3, which is coeval with late Lake Lisan. Geogene processes causing Cu-enriched encrustations overlap with man-made manganiferous slags. The smelter feed has been derived mainly from Cu ore which developed during Late Pleistocene in the region.

    Chemical weathering and mechanical erosion are first-order processes of long-term tropical morphogenesis, which is still poorly deciphered for lack of time constraints. We address this issue by laser probe 39Ar-40Ar dating of generations of cryptomelane [K1-2Mn8O16, nH2O] from the manganese ore deposit of Tambao in northern Burkina Faso. This Mn deposit results from the supergene weathering of carbonate and silicate Mn protores underneath lateritic palaeolandsurfaces. It consists of an upper cryptomelane-rich domain and a lower domain where pyrolusite (β-MnO2) is the dominant Mn oxide. The oldest 39Ar-40Ar ages (59-45 Ma) are obtained on surface outcrops while the youngest ones characterize deep oxidation fronts (3.4-2.9 Ma). Apparent correlations of 39Ar-40Ar age groups with δ18O and eustatic curves allow definition of the different stages of morphogenesis. Paleocene-Eocene ages (59-45 Ma) bracket a greenhouse period propitious to bauxitic weathering. The lack of significant ages between ˜45 and 29 Ma characterizes a period dominated by mechanical erosion, during which detrital sediments, including lateritic materials, were accumulated in intracratonic basins allowing the exhumation of a new lateritic landsurface. Two major weathering periods separated by a second erosion episode (24-18 Ma) are also depicted at the end of Oligocene (29-24 Ma) and lower to mid-Miocene (18-11.5 Ma) in the upper domain, during which newly shaped land surfaces conspicuously weathered. The shorter-weathering and erosion episodes recorded in the lower domain from ˜18 to ˜2.9 Ma led to the final geomorphic changes that were conducive to the formation of glacis. The preservation of old cryptomelane (59-45 Ma) in the upper part of the ore deposit indicates a Cenozoic denudation limited to the erosion of previous bauxites, and partly, of ferricretes.

    As social media (eg, Twitter) continues to gain widespread popularity, health research and practice organizations may consider combining it with other electronic media (e-media) channels (eg, Web sites, e-newsletters) within their communication plans. However, little is known about added benefits of using social media when trying to reach public health audiences about physical activity. Learn about current use and preference for e-media communication channels among physical activity researchers and practitioners. A Web-based survey was used, open for responses from August 20, 2015, through January 5, 2016. Survey participation was voluntary and anonymous. The survey was advertised through multiple channels targeting physical activity researchers and practitioners, including announcements on professional listservs and in e-newsletters, Twitter, and posts on Facebook pages of public health organizations. A total of 284 survey respondents had complete data. Typical use of e-media to receive, seek out, and share information about physical activity and health and what appeals to researchers and practitioners for professional use. Most respondents preferred non-social media channels to social media and these preferences did not differ widely when examining subgroups such as researchers versus practitioners or social media users versus nonusers. There were few differences by respondent demographics, though younger respondents reported using social media more than older respondents. However, limiting analyses to respondents who identified as social media users, only about 1% of respondents ranked social media sources as their preferred channels for information; thus, most people would continue to be reached if communication remained largely via non-social media e-media channels. The present study supports growing evidence that careful surveying of a target audience should be undertaken when considering new communication channels, as preference and use may not support the

    Physical activity participation is an important behavior for modifying lifestyle-related disease risk. Mobile health apps for chronic disease management and prevention are being developed at a rapid rate. However, it is unclear whether these apps are evidence-based. Current public health recommendations for physical activity participation for adults highlight the importance of engaging in 150 minutes weekly of purposeful exercise, and muscle strengthening activities on at least 2 days of the week. The aims of the present review were to (1) identify available evidence-based physical activity apps, and (2) identify technological features that could be leveraged to improve health outcomes. iTunes and Google Play mobile app stores were searched using keyword and category searching during a single day (February 18, 2014) for physical activity apps available in English. The description pages of eligible apps were reviewed by 4 independent reviewers for evidence-based content, technological, and descriptive features. An a priori subset of apps was downloaded for further review (n=6 affiliated with a non-commercial agency; n=10 top rated; n=10 random selection), and developers were contacted for information regarding evidence-informed content. The initial search yielded 2400 apps, of which 379 apps (n=206 iTunes; n=173 Google Play) were eligible. Primary results demonstrated no apps (n=0) adhering to evidence-based guidelines for aerobic physical activity, and 7 out of 379 implementing evidence-based guidelines for resistance training physical activity. Technological features of apps included social networking (n=207), pairing with a peripheral health device (n=61), and measuring additional health parameters (n=139). Secondary results revealed 1 app that referenced physical activity guidelines (150 minutes/weekly of exercise), and demonstrated that apps were based on various physical activity reports (n=4) or personal expertise (n=2).

    A remarkable amount of progress has been made in Physics since the last CMS Week in June given the exponential growth in the delivered LHC luminosity. The first major milestone was the delivery of a variety of results to the ICHEP international conference held in Paris this July. For this conference, CMS prepared 15 Physics Analysis Summaries on physics objects and 22 Summaries on new and interesting physics measurements that exploited the luminosity recorded by the CMS detector. The challenge was incorporating the largest batch of luminosity that was delivered only days before the conference (300 nb-1 total). The physics covered from this initial running period spanned hadron production measurements, jet production and properties, electroweak vector boson production, and even glimpses of the top quark. Since then, the accumulated integrated luminosity has increased by a factor of more than 100, and all groups have been working tremendously hard on analysing this dataset.

    The Angelo State Society of Physics Students Peer Pressure Team travels throughout West-CentralTexas for a week following the spring semester. The goals of this activity are two-fold. First the group seeks to engage undergraduate presenters in public servive; the second goal is to enhance attitudes about science and encourage students in K-12 public schools to study science. Many of the schools we choose for our outreach visits are geographically isolated and populated with socioeconomically disadvantaged students, and/or groups underrepresented in physics. Over the week, the Peer Pressure Team visited over 1300 students, teachers and administrators. At each visit, surveys were collected to gauge the program's effectiveness. Student responses indicate a strong desire to study more science in their regular school curriculum. In addition, results are used to determine which demonstrations leave the most lasting impression on the audience participants. The 2011 Road Tour was dedicated to the 100^th anniversary of the discovery of the nucleus by Rutherford.

  13. Chronic and Acute Relational Risk Factors for Dating Aggression in Adolescence and Young Adulthood.

    Dating aggression is a prevalent and costly public health concern. Using a relational risk framework, this study examined acute and chronic relational risk factors (negative interactions, jealousy, support, and relationship satisfaction) and their effects on physical and psychological dating aggression. The study also examined the interaction between chronic and acute risk, allowing us to assess how changes in acute risk have differing effects depending on whether the individual is typically at higher chronic risk. A sample of 200 youth (100 female) completed seven waves of data, which spanned 9 years from middle adolescence to young adulthood (M age at Wave 1 = 15.83). Using hierarchical linear modeling, analyses revealed both acute (within-person) and chronic (between-person) levels in jealousy, negative interactions, and relationship satisfaction, were associated with physical and psychological dating aggression. Significant interactions between chronic and acute risk emerged in predicting physical aggression for negative interactions, jealousy, and relationship satisfaction such that those with higher levels of chronic risk are more vulnerable to increases in acute risk. These interactions between chronic and acute risk indicate that risk is not static, and dating aggression is particularly likely to occur at certain times for youth at high risk for dating aggression. Such periods of increased risk may provide opportunities for interventions to be particularly effective in preventing dating aggression or its consequences. Taken together, these findings provide support for the role of relational risk factors for dating aggression. They also underscore the importance of considering risk dynamically.

  16. Obesity, physical activity, and the urban environment: public health research needs

    Full Text Available Abstract Persistent trends in overweight and obesity have resulted in a rapid research effort focused on built environment, physical activity, and overweight. Much of the focus of this research has been on the design and form of suburbs. It suggests that several features of the suburban built environment such as low densities, poor street connectivity and the lack of sidewalks are associated with decreased physical activity and an increased risk of being overweight. But compared to suburban residents, inner city populations have higher rates of obesity and inactivity despite living in neighborhoods that are dense, have excellent street connectivity and who's streets are almost universally lined with sidewalks. We suggest that the reasons for this apparent paradox are rooted in the complex interaction of land use, infrastructure and social factors affecting inner city populations. Sometimes seemingly similar features are the result of very different processes, necessitating different policy responses to meet these challenges. For example, in suburbs, lower densities can result from government decision making that leads to restrictive zoning and land use issues. In the inner city, densities may be lowered because of abandonment and disinvestment. In the suburbs, changes in land use regulations could result in a healthier built environment. In inner cities, increasing densities will depend on reversing economic trends and investment decisions that have systematically resulted in distressed housing, abandoned buildings and vacant lots. These varying issues need to be further studied in the context of the totality of urban environments, incorporating what has been learned from other disciplines, such as economics and sociology, as well as highlighting some of the more successful inner city policy interventions, which may provide examples for communities working to improve their health. Certain disparities among urban and suburban populations in

    Objective To examine dating violence perpetration and victimization (physical, psychological, and sexual) and lifetime substance use (alcohol, marijuana, and hard drugs) as longitudinal predictors of adolescents’ risky sexual behavior across one year, and to determine whether predictors varied across adolescents’ gender and ethnicity. Methods A sample of Caucasian, African American, and Hispanic male and female adolescents from 7 public high schools in Texas (N = 882) participated. Adolescents completed self-report measures of dating violence, lifetime substance use, and risky sexual behavior at baseline and, 1-year later, completed a second assessment of their risky sexual behavior. Results Path analysis demonstrated that greater physical dating violence victimization, lifetime alcohol use, lifetime marijuana use, and age (being older) were all significant predictors of risky sexual behavior at the 1-year follow-up. These results did not vary across gender or the three ethnic groups (Caucasian, African American, and Hispanic). Conclusions Overall, substance use was a longitudinal predictor of risky sexual behavior across the three ethnic groups, with physical dating violence victimization being the only type of dating violence longitudinally predicting risky sexual behavior. Prevention efforts should consider the roles of physical dating violence and substance use in preventing risky sexual behavior. PMID:25797949

    Dating violence is commonly perpetrated in adolescence, making it imperative to understand risk factors in order to inform prevention efforts. Although individual norms supporting dating violence are strongly related to its perpetration, few studies have examined their longitudinal impact. Moreover, the influence of class norms (i.e., norms for students in the same grade, cohort, and school) supporting dating violence on perpetration has rarely been studied. The current study examined longitudinal relationships between individual and class norms supporting dating violence and perpetration of physical and psychological dating violence. Participants were two cohorts of sixth graders from 37 schools who were in dating relationships at Wave 1 and 6 months later at Wave 2 (N = 2,022; 43% female; 52% African American, 21% Latino/a, 20% White, and 7% other). The analyses used a multilevel approach, with students represented at Level 1 and classes (n = 74) at Level 2. The models tested direct effects of Wave 1 individual and class norms supporting dating violence on subsequent changes in perpetration of dating violence at Wave 2 and the extent to which gender moderated these relationships. The findings indicated that greater individual norms supporting male dating violence predicted greater change in perpetration of physical and psychological dating violence and greater individual norms supporting female dating violence predicted greater change in perpetration of psychological dating violence. Greater class norms supporting male dating violence predicted greater change in perpetration of physical dating violence; whereas greater class norms supporting female dating violence predicted less change in perpetration of physical dating violence. These findings highlight the need to address norms in early adolescence.

We identify two types of events: events after the balance date, which lead to financial statements adjusting and events after the balance date, which do not lead to financial statements adjusting. The process of authorizing the publishing of the financial statements depends on the structure of the reporting entity, on normalization and on procedures followed in preparing and finalizing the financial statements. Some entities submit the financial statements for approval to their owners after they have been published. In such cases, the financial statements are authorized for publication on the date of publication, not the date they were approved by the owners. The events after the reporting period include all events up to the date the financial statements are authorized for publication, even if those events occur after the public announcement of profit or of other selected financial information.

    Although the scientific community increasingly recognizes that its communication with the public may shape civic engagement with science, few studies have characterized how this communication occurs online. Social media plays a growing role in this engagement, yet it is not known if or how different platforms support different types of engagement. This study sets out to explore how users engage with science communication items on different platforms of social media, and what are the characteristics of the items that tend to attract large numbers of user interactions. Here, user interactions with almost identical items on five of CERN's social media platforms were quantitatively compared over an eight-week period, including likes, comments, shares, click-throughs, and time spent on CERN's site. The most popular items were qualitatively analyzed for content features. Findings indicate that as audience size of a social media platform grows, the total rate of engagement with content tends to grow as well. However...

    Full Text Available Technological human surrogates, including robotic and virtual humans, have been popularly used in various scenarios, including training, education, and entertainment. Prior research has investigated the effects of the surrogate’s physicality and gesturing in human perceptions and social influence of the surrogate. However, those studies have been carried out in research laboratories, where the participants were aware that it was an experiment, and the participant demographics are typically relatively narrow—e.g., college students. In this paper, we describe and share results from a large-scale exploratory user study involving 7,685 people in a public space, where they were unaware of the experimental nature of the setting, to investigate the effects of surrogate physicality and gesturing on their behavior during human–surrogate interactions. We evaluate human behaviors using several variables, such as proactivity and reactivity, and proximity. We have identified several interesting phenomena that could lead to hypotheses developed as part of future hypothesis-based studies. Based on the measurements of the variables, we believe people are more likely to be engaged in a human–surrogate interaction when the surrogate is physically present, but movements and gesturing with its body parts have not shown the expected benefits for the interaction engagement. Regarding the demographics of the people in the study, we found higher overall engagement for females than males, and higher reactivity for younger than older people. We discuss implications for practitioners aiming to design a technological surrogate that will directly interact with real humans.

    Chile has suffered a fast increase in childhood obesity in the last 10 years. As a result, several school programmes have been implemented, however the effectiveness of these needs to be evaluated to identify and prioritize strategies to curve this trend. Cluster randomized controlled trial. Twelve primary public schools chosen at random over three regions of the country will take part in this study. The sample size consisted of a total of 1,655 children. For each region one school will be selected for each of the three nutritional intervention modes and one school will be selected as the control group. The intervention modes consist of the following: Healthy Kiosk and nutritional education (KSEAN); Optimized physical activity (AFSO); Healthy Kiosk and nutritional education (KSEAN) + optimized physical activity (AFSO); Control group. The effectiveness of each intervention will be evaluated by determining the nutritional condition of each child by measuring percentage of body fat, BMI and the z-score of the BMI. This study will also identify the eating behaviours, nutritional knowledge and fitness of each child, along with the effective time of moderate activity during physical education classes. A protocol to evaluate the effectiveness of a school based intervention to control and/or reduce the rates of childhood obesity for children between 6 and 10 years of age was developed. The protocol was developed in line with the Declaration of Helsinski, the Nüremberg Code and the University of Chile Guidelines for ethical committees, and was approved by the INTA, Universidad de Chile ethical committee on Wednesday 12 March 2014. There is consensus among researchers and health and education personnel that schools are a favourable environment for actions to prevent and/or control childhood obesity. However a lack of evidence on the effectiveness of interventions to date has led some to question the wisdom of allocating resources to programmes. This is the first study

    Full Text Available Os objetivos foram estimar a prevalência de perpetração de violência física e psicológica entre adolescentes namorados de Recife, identificar fatores associados e a coocorrência de ambos os tipos de violência. Participaram do estudo 302 adolescentes de escolas públicas e particulares, com idade entre 15 e 19 anos, que tiveram algum relacionamento amoroso no último ano e esses preencheram o questionário. Foram realizadas análise univariada e regressão logística e todas as análises estatísticas incorporaram o peso amostral e o desenho da amostra complexa. A prevalência de violência física foi de 19,9%, de 82,8% para violência psicológica e de 18,9% para a coocorrência de violência física e psicológica. Os adolescentes que vivenciaram violência na comunidade e em relacionamentos de mais de um ano de duração apresentaram maiores chances de perpetrar violência psicológica. Enquanto, sofrer violência física do pai, entre irmãos e em namoros anteriores, além de ter perpetrado violência verbal em relacionamentos anteriores, foram variáveis que aumentaram a chance de perpetração de violência física e psicológica no namoro. Conclui-se que a violência psicológica e a coocorrência de violência física e psicológica possuem uma dinâmica distinta da violência física no namoro.The scope of this study was to assess the prevalence of physical and psychological violence among dating adolescents from Recife, Brazil, to identify associated factors and the co-occurrence of both types of violence. 302 adolescents aged between 15 and 19 years in public and private schools who were in a relationship in the last year filled out the questionnaire. Univariate and multivariate logistic regression statistical analysis were performed and the sample weight and the complex sample design were entered.

    of Bern, and International Atomic Energy Agency. ATTA is a laser-based atom counting method, not a mass spectrometry method. A magneto-optical trap is used to capture neutral atoms (rather than ions) of the desired isotope using laser beams. A photo-sensor detects the laser induced fluorescence emitted by the individual trapped atoms. ATTA is unique among trace analysis techniques in that it is free of interferences from any other isotopes, isobars, atomic or molecular species. In an experiment demonstrating that ATTA-3 can analyze 39Ar/Ar ratios in environmental samples, no interference from other atomic or molecular species was observed at the 1x10^-16 level (Jiang et al., Phys. Rev. Lett. 106, 103001; 2011). This work proved the feasibility of performing 39Ar dating using the ATTA method.

    There have been two plenary physics meetings since the December CMS week. The year started with two workshops, one on the measurements of the Standard Model necessary for “discovery physics” as well as one on the Physics Analysis Toolkit (PAT). Meanwhile the tail of the “2007 analyses” is going through the last steps of approval. It is expected that by the end of January all analyses will have converted to using the data from CSA07 – which include the effects of miscalibration and misalignment. January Physics Days The first Physics Days of 2008 took place on January 22-24. The first two days were devoted to comprehensive re¬ports from the Detector Performance Groups (DPG) and Physics Objects Groups (POG) on their planning and readiness for early data-taking followed by approvals of several recent studies.

    The all-plenary format of the CMS week in Cyprus gave the opportunity to the conveners of the physics groups to present the plans of each physics analysis group for tackling early physics analyses. The presentations were complete, so all are encouraged to browse through them on the Web. There is a wealth of information on what is going on, by whom and on what basis and priority. The CMS week was followed by two CMS “physics events”, the ICHEP08 days and the physics days in July. These were two weeks dedicated to either the approval of all the results that would be presented at ICHEP08, or to the review of all the other Monte-Carlo based analyses that were carried out in the context of our preparations for analysis with the early LHC data (the so-called “2008 analyses”). All this was planned in the context of the beginning of a ramp down of these Monte Carlo efforts, in anticipation of data.  The ICHEP days are described below (agenda and talks at: http://indic...

    The effect on public policy of macro to nano aspects of the deadliest Illness known to mankind is given. The focus is on the important role of physics which has been ignored so far to solve its problems. It is now acknowledged that the deadliest illness is actually a group of illnesses which are lumped together as mental illnesses. They are the most widespread and damaging illnesses in the world. Their impact on the entire society globally is huge because they afflict majority of the people irrespective of race, religion, sex, age, education and economic status. In USA alone, the number afflicted according to the official count is about 80 million (out of a total population of 315 million), and it is projected to increase to about 25 to 30% of the population within two decades. A model is given in this paper to address some of the key issues from macro to nano aspects of the deadliest illness. The information given in this paper is scientific though easy to understand. It will help the elected policy makers, public, physicists, neuroscientists, doctors, and care giving personnel world wide. The model explains the missing links in the diagnosis and treatment of mental illnesses. Additional evidence from other recent studies shall also be given.

    Despite the recent rapid development of policies to counteract physical inactivity (PI), only a small number of systematic analyses on the evolution of these policies exists. In this article we analyze how PI, as a public health issue, "translates" into a policy-making issue. First, we discuss why PI has become an increasingly important public health issue during the last two decades. We then follow Guy Peters and conceptualize PI as a "policy problem" that has the potential to be linked to policy instruments and policy impact. Analysis indicates that PI is a policy problem that i) is chronic in nature; ii) involves a high degree of political complexity; iii) can be disaggregated into smaller scales; iv) is addressed through interventions that can be difficult to "sell" to the public when their benefits are not highly divisible; v) cannot be solved by government spending alone; vi) must be addressed through a broad scope of activities; and vii) involves interdependencies among both multiple sectors and levels of government.We conclude that the new perspective on PI proposed in this article might be useful and important for i) describing and mapping policies to counteract PI in different contexts; ii) evaluating whether or not existing policy instruments are appropriate to the policy problem of PI, and iii) explaining the factors and processes that underlie policy development and implementation. More research is warranted in all these areas. In particular, we propose to focus on comparative analyses of how the problem of PI is defined and tackled in different contexts, and on the identification of truly effective policy instruments that are designed to "solve" the PI policy problem.

    The time period between the last CMS week and this June was one of intense activity with numerous get-together targeted at addressing specific issues on the road to data-taking. The two series of workshops, namely the “En route to discoveries” series and the “Vertical Integration” meetings continued.   The first meeting of the “En route to discoveries” sequence (end 2007) had covered the measurements of the Standard Model signals as necessary prerequisite to any claim of signals beyond the Standard Model. The second meeting took place during the Feb CMS week and concentrated on the commissioning of the Physics Objects, whereas the third occurred during the April Physics Week – and this time the theme was the strategy for key new physics signatures. Both of these workshops are summarized below. The vertical integration meetings also continued, with two DPG-physics get-togethers on jets and missing ET and on electrons and photons. ...

    Since the last CMS Week, all physics groups have been extremely active on analyses based on the full 2010 dataset, with most aiming for a preliminary measurement in time for the winter conferences. Nearly 50 analyses were approved in a “marathon” of approval meetings during the first two weeks of March, and the total number of approved analyses reached 90. The diversity of topics is very broad, including precision QCD, Top, and electroweak measurements, the first observation of single Top production at the LHC, the first limits on Higgs production at the LHC including the di-tau final state, and comprehensive searches for new physics in a wide range of topologies (so far all with null results unfortunately). Most of the results are based on the full 2010 pp data sample, which corresponds to 36 pb-1 at √s = 7 TeV. This report can only give a few of the highlights of a very rich physics program, which is listed below by physics group...

    We examined the association between witnessing interparental violence, attitudes about dating violence, and physical and psychological teen dating violence (TDV) victimization. Participants were 918 teens with dating experience. Witnessing interparental violence and acceptance of dating violence were significant predictors of TDV victimization. Acceptance of dating violence was also a partial mediator between witnessing interparental violence and TDV victimization. Witnessing mother-to-father violence and acceptance of female-perpetrated violence were the most consistent predictors. TDV programs aiming to prevent victimization could benefit from targeting youth exposed to father-to-mother and mother-to-father violence, targeting attitudes about violence, and tailoring interventions to gender-specific risk factors.

      The period since the last CMS Bulletin has been historic for CMS Physics. The pinnacle of our physics programme was an observation of a new particle – a strong candidate for a Higgs boson – which has captured worldwide interest and made a profound impact on the very field of particle physics. At the time of the discovery announcement on 4 July, 2012, prominent signals were observed in the high-resolution H→γγ and H→ZZ(4l) modes. Corroborating excess was observed in the H→W+W– mode as well. The fermionic channel analyses (H→bb, H→ττ), however, yielded less than the Standard Model (SM) expectation. Collectively, the five channels established the signal with a significance of five standard deviations. With the exception of the diphoton channel, these analyses have all been updated in the last months and several new channels have been added. With improved analyses and more than twice the i...

The first large batch of physics approvals is scheduled for this CMS Week, to be followed by four more weeks of approvals and analysis updates leading to the start of the conference in July. Several high priority analysis areas were organized into task forces to ensure sufficient coverage from the relevant detector, object, and analysis groups in the preparation of these analyses. Already some results on charged particle correlations and multiplicities in 7 TeV minimum bias collisions have been approved. Only one small detail remains before ICHEP: further integrated luminosity delivered by the LHC!

    The collisions last year at 900 GeV and 2.36 TeV provided the long anticipated collider data to the CMS physics groups. Quite a lot has been accomplished in a very short time. Although the delivered luminosity was small, CMS was able to publish its first physics paper (with several more in preparation), and commence the commissioning of physics objects for future analyses. Many new performance results have been approved in advance of this CMS Week. One remarkable outcome has been the amazing agreement between out-of-the-box data with simulation at these low energies so early in the commissioning of the experiment. All of this is testament to the hard work and preparation conducted beforehand by many people in CMS.

    Dating violence is a major public health issue among youth. Overweight/obese adolescents experience peer victimization and discrimination and may be at increased risk of dating violence victimization. Furthermore, given the stigma associated with overweight/obesity, perceptions and misperceptions of overweight may be more important than actual weight status for dating violence victimization. This study examines the association of three weight indices (weight status, perceived weight, and weight perception accuracy) with psychological and physical dating violence victimization. The 2010 baseline survey of the 7-year NEXT Generation Health Study used a three-stage stratified clustered sampling design to select a nationally representative sample of U.S. 10th-grade students (n = 1,983). Participants who have had a boyfriend/girlfriend reported dating violence victimization and perceived weight. Weight status was computed from measured height/weight. Weight perception accuracy (accurate/underestimate/overestimate) was calculated by comparing weight status and perceived weight. Gender-stratified regressions examined the association of weight indices and dating violence victimization. Racial/ethnic differences were also examined. The association of weight indices with dating violence victimization significantly differed by gender. Overall, among boys, no associations were observed. Among girls, weight status was not associated with dating violence victimization, nor with number of dating violence victimization acts; however, perceived weight and weight perception accuracy were significantly associated with dating violence victimization, type of victimization, and number of victimization acts. Post hoc analyses revealed significant racial/ethnic differences. White girls who perceive themselves (accurately or not) to be overweight, and Hispanic girls who are overweight, may be at increased risk of dating violence victimization. These findings suggest a targeted approach to

The Panel noted that the Gift et al. (2013 review of the ERF studies is consistent with EFSA’s conclusions on the lack of carcinogenic activity of aspartame. The Panel also analysed US-EPA’s Toxicological Review of Methanol (Noncancer in the context of the safety assessment of aspartame. The Panel noted that the combination of the endpoint used, a benchmark dose response (BMR of 5% and the uncertainty factors applied, resulted in a Reference Dose (RfD for exogenous methanol of 2 mg/kg bw/day that was overly conservative. This RfD was by definition in addition to dietary intakes of methanol which were included in the background exposure estimates used by the US EPA. Taking all these factors into consideration, the Panel concluded that the toxicological review of methanol by US-EPA and the review by Gift et al.

    Adolescent dating violence and electronic aggression are significant public health problems. The purpose of this study was to (a) identify ways in which technology is used in dating violence and (b) present examples of dating violence in which electronic aggression played a salient role. The data set included the transcribed narratives of 56 young adults who had described their adolescent dating violence experiences for an on going study. Eight ways in which technology is used in dating violence were identified using qualitative descriptive methods. The findings indicate that electronic communication technology influences dating violence by redefining boundaries between dating partners.

    It is now recognised that inactive lifestyles underpin much of the disease burden evident in the richer nations of the world. Indeed, the WHO has identified physical inactivity as a 'global public health problem' and has established minimum physical activity (PA) targets for people at different stages of the life-course. Yet, according to WHO, just under 1/3 of working age adults across the globe meet those targets and it is not at all clear how the disjunction between the recommendations of policy makers and the behaviour of ordinary people might be surmounted. Using an opportunity to examine the impact of an urban regeneration project on community residents in East Belfast (Northern Ireland) this paper examines the views of some 113 people on how to increase rates of PA in an area of multiple deprivation. The results of the analysis suggest that lay people rarely consider PA as a discrete issue, or one that centres on individuals and their motivation, but rather as one component in a complex web of concerns, processes and events that include such things as the actions of neighbours and relatives, material and political environments, vandalism, violence, and the weather. We explore and unravel the nature of those concerns using novel methods of content analysis that generate 'issue webs'. Particular attention is paid to the ways in which lay people conceptualize 'activity' and to the manner in which they point to ways of encouraging activity that are rooted in everyday life rather than in the corpocentric, agent-centred and often sport dominated strategies favoured by local policy makers. Our results support those who argue that interventions to increase rates of PA need to move beyond behavioural approaches that focus on individuals and consider the social, political and material contexts in which 'activity' occurs.

    The Electroweak and Top Quark Workshop (16-17th of July) A Workshop on Electroweak and Top Quark Physics, dedicated on early measurements, took place on 16th-17th July. We had more than 40 presentations at the Workshop, which was an important milestone for 2007 physics analyses in the EWK and TOP areas. The Standard Model has been tested empirically by many previous experiments. Observables which are nowadays known with high precision will play a major role for data-based CMS calibrations. A typical example is the use of the Z to monitor electron and muon reconstruction in di-lepton inclusive samples. Another example is the use of the W mass as a constraint for di-jets in the kinematic fitting of top-quark events, providing information on the jet energy scale. The predictions of the Standard Model, for what concerns proton collisions at the LHC, are accurate to a level that the production of W/Z and top-quark events can be used as a powerful tool to commission our experiment. On the other hand the measure...

    In the period since the last CMS Bulletin, the LHC – and CMS – have entered LS1. During this time, CMS Physics Analysis Groups have performed more than 40 new analyses, many of which are based on the complete 8 TeV dataset delivered by the LHC in 2012 (and in some cases on the full Run 1 dataset). These results were shown at, and well received by, several high-profile conferences in the spring of 2013, including the inaugural meeting of the Large Hadron Collider    Physics Conference (LHCP) in Barcelona, and the 26th International Symposium on Lepton Photon Interactions at High Energies (LP) in San Francisco. In parallel, there have been significant developments in preparations for Run 2 of the LHC and on “future physics” studies for both Phase 1 and Phase 2 upgrades of the CMS detector. The Higgs analysis group produced five new results for LHCP including a new H-to-bb search in VBF production (HIG-13-011), ttH with H to γ&ga...

    The period since the last CMS bulletin has seen the end of proton collisions at a centre-of-mass energy 8 TeV, a successful proton-lead collision run at 5 TeV/nucleon, as well as a “reference” proton run at 2.76 TeV. With these final LHC Run 1 datasets in hand, CMS Physics Analysis Groups have been busy analysing these data in preparation for the winter conferences. Moreover, despite the fact that the pp run only concluded in mid-December (and there was consequently less time to complete data analyses), CMS again made a strong showing at the Rencontres de Moriond in La Thuile (EW and QCD) where nearly 40 new results were presented. The highlight of these preliminary results was the eagerly anticipated updated studies of the properties of the Higgs boson discovered in July of last year. Meanwhile, preparations for Run 2 and physics performance studies for Phase 1 and Phase 2 upgrade scenarios are ongoing. The Higgs analysis group produced updated analyses on the full Run 1 dataset (~25 f...

  5. USEMS & GLASS: investigator-driven frontier research in earthquake physics. Ground-breaking research in Europe enhances outreach to the general public

    2011-12-01

    USEMS and GLASS are two projects financed by the European Research Council (ERC) as part of the ERC starting grants scheme within the FP7 framework. The rationale behind the funding scheme is to support some of the most promising scientific endeavours in Europe that are being led by young researchers, and to emphasize the excellence of individual ideas rather than specific research areas; in other words, to promote bottom-up frontier research. The general benefits of this rationale are evident in the two ongoing projects that deal with earthquake physics, as these projects are increasingly recognized in their scientific community. We can say that putting excellence at the heart of European Research strongly contributes to the construction of a European knowledge-based society. From a researcher point-of-view one of the most challenging aspects of these projects is to approach and convey the results of the projects to a general public, contributing to the construction of knowledge-based society. Luckily, media interest and the availability of a number of new communication tools facilitate the outreach of scientific achievements. The largest earthquakes during the last ten years (e.g. Sumatra 2004 and Japan 2011) have received widespread attention in the media world (TV, W.W.W., Newspaper and so on) for months, and successful research projects such as those above also become media protagonists, gaining their space in the media bullring. The USEMS principal investigator and his team have participated in several dissemination events in the Mass Media, such as interviews wit Italian and French TV national broadcasts (RAI Due TG2, RAI Uno Unomattina, Rai Tre Geo & Geo, FRANCE 2); interviews in scientific journals: SCIENCE (Sept. 2010), newspapers and web (Corriere della Sera, Il Gazzettino, Il Messagero, La Stampa, Libero, Il Mattino, Yahoo, ANSA, AdnKronos and AGI); radio (RadioRai Uno, RadioRai Tre Scienza); documentary "Die Eroberung der Alpen" produced by Tangram

    It is well known that physical activity and exercise is associated with a lower risk of a range of morbidities and all-cause mortality. Further, it appears that risk reductions are greater when physical activity and/or exercise is performed at a higher intensity of effort. Why this may be the case is perhaps explained by the accumulating evidence linking physical fitness and performance outcomes (e.g. cardiorespiratory fitness, strength, and muscle mass) also to morbidity and mortality risk. Current guidelines about the performance of moderate/vigorous physical activity using aerobic exercise modes focuses upon the accumulation of a minimum volume of physical activity and/or exercise, and have thus far produced disappointing outcomes. As such there has been increased interest in the use of higher effort physical activity and exercise as being potentially more efficacious. Though there is currently debate as to the effectiveness of public health prescription based around higher effort physical activity and exercise, most discussion around this has focused upon modes considered to be traditionally 'aerobic' (e.g. running, cycling, rowing, swimming etc.). A mode customarily performed to a relatively high intensity of effort that we believe has been overlooked is resistance training. Current guidelines do include recommendations to engage in 'muscle strengthening activities' though there has been very little emphasis upon these modes in either research or public health effort. As such the purpose of this debate article is to discuss the emerging higher effort paradigm in physical activity and exercise for public health and to make a case for why there should be a greater emphasis placed upon resistance training as a mode in this paradigm shift.

    The main programme of the Physics Week held between 16th and 20th May was a series of topology-oriented workshops on di-leptons, di-photons, inclusive W, and all-hadronic final states. The goal of these workshops was to reach a common understanding for the set of objects (ID, cleaning...), the handling of pile-up, calibration, efficiency and purity determination, as well as to revisit critical common issues such as the trigger. Di-lepton workshop Most analysis groups use a di-lepton trigger or a combination of single and di-lepton triggers in 2011. Some groups need to collect leptons with as low PT as possible with strong isolation and identification requirements as for Higgs into WW at low mass, others with intermediate PT values as in Drell-Yan studies, or high PT as in the Exotica group. Electron and muon reconstruction, identification and isolation, was extensively described in the workshop. For electrons, VBTF selection cuts for low PT and HEEP cuts for high PT were discussed, as well as more complex d...

  12. Bullying and HIV Risk Among High School Teenagers: The Mediating Role of Teen Dating Violence.

    Teen dating violence (TDV), bullying, and HIV risk behaviors are public health concerns that impact adolescents in the United States. National estimates reveal high rates of these risk behaviors among high school students. Based on theoretical and empirical evidence, we hypothesized that experiencing teen dating violence (sexual and physical) would mediate the impact of bullying on HIV risk. Data were from the 2013 National Youth Behavior Risk Surveillance Survey (YRBSS) among students who answered questions on bullying, TDV, and HIV risk (N = 13,571). The YRBSS is conducted biennially among 9th- to 12th-grade students nationally. We used multiple regression analysis and Hayes' SPSS process macro to examine the 2 study hypotheses. Findings from bivariate analysis suggest an association between bullying and HIV risk. The study also found associations between physical, sexual teen dating violence and HIV risk. Results also indicate that both physical and sexual teen dating violence mediate the association between bullying and HIV risk. Our findings suggest that multidimensional interventions should be developed to reduce the rate of teen dating violence and combat bullying as a preventative method for HIV risk among high school students. © 2017, American School Health Association.

    Full text: Opal phytoliths are microscopic silica bodies formed by the precipitation of hydrated silica dioxide (SiO{sub 2}nH{sub 2}0) in, around and between cell walls. They are relatively resistant to degradation in most environments and thus, can occur in large quantities in palaeosediments. Consequently, they are valuable tools for environmental reconstruction. Furthermore, phytoliths are often the only recoverable organic material in well oxidised sediments, the occluded carbon provides the opportunity for dating sediment whose ages have previously been difficult to determine, and thus, increase the potential for fine resolution determination of environmental change. This poster describes the results of an investigation assessing the viability of AMS radiocarbon dating of fossil phytolith inclusions using samples from Garua Island, West New Britain, PNG. Thirteen phytolith samples, isolated from sediments previously dated using tephrastratigraphy and C14 dating of macroremains of nutshells and wood charcoal, were used in the analysis. As a control measure, thirteen parallel samples of microscopic charcoal were also dated using AMS. The results show that the AMS dates for the microscopic charcoal samples are consistent with ages anticipated from the other dating methods, for all but one sample. However, the dates for eight of the thirteen phytolith samples are considerably younger than expected. This bias could be explained by several factors, including downwashing of phytolith through soils, bioturbation, carbon exchange through the siliceous matrix of the phytolith bodies, and contamination from extraneous sources of modern carbon retained in the samples. Research is currently focusing on the investigation of these issues and selected samples are in the process of being retreated with strong oxidising agents to clear contaminants prior to re-dating. Further to this, a full investigation of one profile with a long sequence is underway. High concentrations of

    To assess the relationship between physical performance (PP) and muscle strength (MS) in elderly subjects with and without diabetes in a public hospital of Lima, Peru. A cross-sectional analysis of subjects aged 60 years or older with and without diabetes. MS was measured with a handheld dynamometer, and PP with the «timed get-up-and-go» test. Nutritional status was determined using body mass index, body fat percentage measured with a handheld fat loss monitor and protein intake based on the 24-hour recall. Age, sex, and history of hospitalization and supplementation were also recorded. The association was assessed using adjusted prevalence ratios. Overall, 139 patients with diabetes (26.6% with low PP and 13.7% with decreased MS) and 382 subjects without diabetes (36.6% with low PP and 23.0% with decreased MS) were evaluated. No association was found between T2DM and MS (aPR: 0.99; 95% CI: 0.67-1.57) or PP (aPR: 1.13; 95% CI: 0.84-1.52). Protein and supplement consumption was also unrelated (P>.05); however, history of hospitalization, age, sex, nutritional status, and body fat percentage were related (P>.05). No association was found between T2DM, MS, and PP. However, low PP was associated to female sex and overweight/obesity, and decreased MS was associated to high body fat percentage and underweight. Moreover, MS and PP were related to older age and history of hospitalization. Copyright © 2016 SEEN. Published by Elsevier España, S.L.U. All rights reserved.

    2012-03-01

    Built environment characteristics have been linked to health outcomes and health disparities. However, the effects of an environment on behavior may depend on human perception, interpretation, motivation, and other forms of human agency. We draw on epidemiological and ethical concepts to articulate a critique of research on the built environment and physical activity. We identify problematic assumptions and enumerate both scientific and ethical reasons to incorporate subjective perspectives and public engagement strategies into built environment research and interventions. We maintain that taking agency seriously is essential to the pursuit of health equity and the broader demands of social justice in public health, an important consideration as studies of the built environment and physical activity increasingly focus on socially disadvantaged communities. Attention to how people understand their environment and navigate competing demands can improve the scientific value of ongoing efforts to promote active living and health, while also better fulfilling our ethical obligations to the individuals and communities whose health we strive to protect.

    Full Text Available Dating violence in Mexico is a serious problem because 76% of young Mexicans have suffered psychological violence, 15% have suffered physical violence and 16.5% have suffered sexual violence (Mexican Youth Institute, 2008. Therefore it has been given increasing attention to the study of this phenomenon in numerous researches. Knowing the characteristics of this production would allow to consolidate or to open up new research lines, so this narrative review discusses the main methodological characteristics of research on dating violence in Mexican university students. It was included twenty scientific researches published by Mexicans and foreigners researchers between 2002 and 2012 in scientific journals or presented at scientific conferences, with samples consisting of Mexican university students aged between 18 and 25 years. The search was conducted in specialized databases such as Dialnet, Google Scholar, Psicodoc, Psycinfo, Redalyc and Scirus. The results show that 75% of the studies were quantitative designs, 100% was cross-sectional design and 85% had nonrandom sample. 95% of the samples were formed by students from public universities and 15% used an internationally validated questionnaire and controlled social desirability of responses. It concludes the need for more studies with mixed, dyadic or longitudinal designs, but with samples randomly selected from public and private universities. The need of control of social desirability of responses and the implementation of validated questionnaires to allow comparisons between results.

    The potential of the time-dependent amino acid racemisation reaction as a method of age assessment was first reported by Hare and Abelson (1968). They noted that in specimens of the bivalve mollusc Mercenaria sp., greater concentrations of amino acids in the D-configuration with increasing fossil age. Hare and Abelson (1968) also reported negligible racemisation in a modern specimen of Mecanaria sp. On this basis they suggested that the extent of amino acid racemisation (epimerisation in the case of isoleucine) may be used to assess the age of materials within and beyond the range of radiocarbon dating. For the past thirty years amino acid racemisation has been extensively applied in Quaternary research as a method of relative and numeric dating, and a particularly large literature has emerged on the subject 12 refs.

    2011-11-15

    Aim: To document the timing of the appearance of the radiological features of fracture healing in a group of infants in which the date of injury was known and to assess the degree of interobserver agreement. Materials and methods: Three paediatric radiologists independently assessed 161 images of 37 long bone fractures in 31 patients aged 0-44 months. The following features were assessed: soft-tissue swelling, subperiosteal new bone formation (SPNBF), definition of fracture line, presence or absence of callus, whether callus was well or ill defined, and the presence of endosteal callus. Results: Agreement between observers was only moderate for all discriminators except SPNBF. SPNBF was invariably seen after 11 days but was uncommon before this time even in the very young. In one case SPNBF was seen at 4 days. Conclusion: With the exception of SPNBF, the criteria relied on to date fractures are either not reproducible or are poor discriminators of fracture age.

    2008-06-01

    Full Text Available The aim of this study is to analyze the opinion of Physical Education teachers about dancing activities in the first four grades of elementary schools of the state public school system in the municipality of Maringá, state of Paraná. The sample comprised nineteen Physical Education teachers from fifteen of the twenty-nine schools chosen at random in a descriptive research. The data were collected by the researchers through the application of open and guided questionnaires to the teachers after their Physical Education classes. The data were analyzed by the descriptive statistics method. The results showed that the teachers consider that dancing develops the children’s corporal consciousness besides exploring their possibilities of movement. It may also be concluded that lack of theoretical knowledge and of adequate facilities and materials in the schools are the main hampering factors for the teachers to develop dancing activities.

Transit times across the public internet exhibit a degree of randomness, and cannot be determined noiselessly by an eavesdropper. We demonstrate the use of these measurements for information-theoretically secure communication over the public internet.

    There have been studies conducted on the effectiveness of the transtheoretical model (TTM) in improving the level of physical activity at worksites worldwide, but no such studies have been conducted in South Africa. The aim of this study was to determine the predictive validity and effects of using the Transtheoretical Model to increase the physical activity of healthcare workers in a public hospital in South Africa. A quasi-experimental design in the form of a single-group, pretest-posttest model was used to examine the possible relationship between an exposure to interventions, attitude, knowledge, and an increased level of physical activity. Two hundred hospital staff members (medical and nonmedical staff) were randomly selected for participation in the study. The following variables were measured: TTM stages of physical activity, knowledge and attitudes, fitness level, body mass index, and level of exposure to the intervention. The interventions designed were based on the concept of progressing stages of physical activity in TTM stage sequences: (1) pamphlets about physical activity and health, (2) posters, fun runs, and sports day, and (3) a second set of posters, a daily radio program, and aerobic classes. Post-intervention, participants had significantly increased their stages of physical activity, attitudes, and knowledge compared with their pre-tests. Mean scores of TTM (3.70) and knowledge (3.65) were significantly (p < 0.05) greater at post-test. Overall accuracies of TTM at pre-test correctly predicted TTM at post-test by an average of 66.9%. The use of TTM to identify the stage of physical activity of healthcare workers has enabled the researcher to design intervention programs specific to the stage of exercise behavior of hospital staff. The predictors (TTM1), exposure levels, knowledge, attitudes, and processes of change have significant contributions to the outcome (TTM2).

    Full Text Available This article results from a qualitative research, anchored by the methodology of oral history as investigative support. The study aimed to understand the narratives of two young university students about the phenomenon of violence in dating relationships. In this perspective, it is important to unveil the arguments supported in order to mantain a relationship of violence, requiring the understanding of the meanings they attribute to the type of violence suffered. Thus, this study sought to investigate gender violence, that is, the actions or conduct, based on gender differences, which may cause death, physical, sexual or psychological suffering to women, because these events may occur both in the public and private space. Gender violence expresses the historically unequal power relations between men and women.

  20. 210Pb dating

    Swarzenski, Peter W.

    2014-01-01

    Roughly fifty years ago, a small group of scientists from Belgium and the United States, trying to better constrain ice sheet accumulation rates, attempted to apply what was then know about environmental lead as a potential geochronometer. Thus Goldberg (1963) developed the first principles of the 210Pb dating method, which was soon followed by a paper by Crozaz et al. (1964), who examined accumulation history of Antarctic snow using 210Pb. Shortly thereafter, Koide et al. (1972, 1973) adapted this technique to unravel sediment deposition and accumulation records in deep-sea environments. Serendipitously, they chose to work in a deep basin off California, where an independent and robust age model had already been developed. Krishanswami et al. (1971) extended the use of this technique to lacustrine deposits to reconstruct depositional histories of lake sediment, and maybe more importantly, contaminant inputs and burial. Thus, the powerful tool for dating recent (up to about one century old) sediment deposits was established and soon widely adopted. Today almost all oceanographic or limnologic studies that address recent depositional reconstructions employ 210Pb as one of several possible geochronometers (Andrews et al., 2009; Gale, 2009; Baskaran, 2011; Persson and Helms, 2011). This paper presents a short overview of the principles of 210Pb dating and provides a few examples that illustrate the utility of this tracer in contrasting depositional systems. Potential caveats and uncertainties (Appleby et al., 1986; Binford, 1990; Binford et al., 1993; Smith, 2001; Hancock et al., 2002) inherent to the use and interpretation of 210Pb-derived age-models are also introduced. Recommendations as to best practices for most reliable uses and reporting are presented in the summary.

    We consider whether the long term perturbation of radiocarbon dates, which is known to be approximately a sin function of period about 8000 years and amplitude of about 8% peak-to-peak, could have been caused in any major part by vulcanism. We conclude that this is not the case. On the contrary, present day volcanoes are a far less important source of inert CO{sub 2} (about 100 fold less) than is man's burning of fossil fuels which has caused the Suess dilution of about 2%.

    In 2016, the ATLAS experiment at CERN released data from 100 trillion proton-proton collisions to the general public. In connection to this release the ATLAS Outreach group has developed several tools for visualizing and analyzing the data, one of which is a Histogram analyzer. The focus of this project is to bridge the gap between the general public's knowledge in physics and what is needed to use this Histogram analyzer. The project consists of both the development and an evaluation of a learning resource that explains experimental particle physics for a general public audience. The learning resource is a website making use of analogies and two perspectives on learning: Variation Theory and Cognitive Load Theory. The evaluation of the website was done using a survey with 10 respondents and it focused on whether analogies and the perspectives on learning helped their understanding. In general the respondents found the analogies to be helpful for their learning, and to some degree they found the explanations ...

    Poor health outcomes from insufficient physical activity (PA) are a persistent public health issue. Public transit is often promoted for positive influence on PA. Although there is cross-sectional evidence that transit users have higher PA levels, this may be coincidental or shifted from activities such as recreational walking. We use a quasi-experimental design to test if light rail transit (LRT) generated new PA in a neighborhood of Salt Lake City, Utah, USA. Participants (n=536) wore Global Positioning System (GPS) receivers and accelerometers before (2012) and after (2013) LRT construction. We test within-person differences in individuals' PA time based on changes in transit usage pre- versus post-intervention. We map transit-related PA to detect spatial clustering of PA around the new transit stops. We analyze within-person differences in PA time based on daily transit use and estimate the effect of daily transit use on PA time controlling for socio-demographic variables. Results suggest that transit use directly generates new PA that is not shifted from other PA. This supports the public health benefits from new high quality public transit such as LRT.

  10. Flirting in Online Dating

    DEFF Research Database (Denmark)

    Mortensen, Kristine Køhler

    2017-01-01

    Various fields have examined the activity of flirting, predominantly based on experimental and reported data; the interactional workings are therefore often overlooked. Based on emails and chats from two Danish online dating sites, this article investigates how users negotiate romantic connections...... through the flirting strategy of ‘imagined togetherness’, linguistically constructing imagery of a shared future. Using the notion of the chronotope (Bakhtin 1981), turn-by-turn analysis demonstrates how users, embedded in the activity of getting to know each other, tenuously communicate romantic interest...... by alluding to future points at which they might be together. Central to the strategy is a sequential pattern of avoiding closure and thereby preserving the imagery’s implicitness. The article concludes by arguing that while imagined togetherness functions a way of probing interests and thus protecting...

    Dating abuse is a prevalent adolescent health problem with substantial public health consequences. As many as 1 in 10 high school students in the United States reports being "hit, slapped, or physically hurt on purpose" by his or her boyfriend or girlfriend in the past year. The authors used the Rihanna-Chris Brown dating abuse incident of 2009 as a case study to conduct what is, to our knowledge, the first assessment of media framing of dating abuse. The authors reviewed the 20 leading U.S. single-copy sales magazines published from February to April 2009 and identified 48 relevant articles, which were all printed in 7 tabloid magazines. The authors conducted a content analysis of the media frames of the articles using 5 frame categories: (a) abuse is objectionable, (b) victim-blaming, (c) abuse is sexualized/romanticized, (d) myths about abuse perpetration, and (e) abuse is normalized. Abuse is objectionable was the dominant frame of 40% of articles, victim-blaming in 36%. Although the majority of articles reviewed (83%) made at least passing reference to the idea that abuse is wrong, a minority (40%) used a dominant frame that condemned abuse. Instead, the majority of articles communicated mixed messages about dating abuse, and many minimized the seriousness of partner abuse perpetration. Advocacy is needed to improve future tabloid media framing of dating abuse incidents.

Dietary fiber, proximate analysis, micronutrients (micro-elements and macro-elements) and physical properties (weight, length, and density) of the selected 18 leading varieties of dates cultivated in the United Arab Emirates-namely Khalas, Barhe, Lulu, Shikat alkahlas, Sokkery, Bomaan, Sagay, Shishi, Maghool, Sultana, Fard, Maktoomi, Naptit saif, Jabri, Khodary, Dabbas, Raziz and Shabebe-were determined and compared. Significant differences (P date fruits, depending on the variety, contain significant but quite variable amounts of macro-elements and micro-elements. The macro-elements measured are calcium, phosphorous, sodium, potassium and magnesium, while the essential micro-elements and the possibly essential micro-elements are iron, zinc, copper, manganese, cobalt and molybdenum, and aluminum, arsenic, barium, cadmium, chromium, nickel, lead, strontium and vanadium, respectively.

  4. Thermoluminescence dating of flint

    Science.gov (United States)

    Valladas, H.

    Our ancestors have been making flint tools for over a million years. The tools or the flakes left by the flint-knappers have become important markers of prehistoric habitats. The imperishable and ubiquitous nature of flint explains why generations of prehistorians have used it to build a stone age chronology. To be dateable by TL flint must be heated to at least 450°C. While human use of fire may be as old as half a million years, the first true hearths appear late during the Lower Paleolithic period. At Terra-Amata, one of the oldest hearths discovered in France was dated to 230 ± 40 ka BP by Wintle and Aitken (1977). By the dawn of the Middle Paleolithic fire must have become fully domesticated, judging by the accumulations of charred debris that henceforth litter human habitats. For example, at the Middle Paleolithic site of Kebara the profusion of hearths is vividly illustrated by numerous superposed white ash and black charcoal layers extending to a depth of 4 m (Meignen et al., 1989).

    Physical fitness testing is a common tool for motivating employees with strenuous occupations to reach and maintain a minimum level of fitness. Nevertheless, the use of such tests can be hampered by several factors, including required compliance with US antidiscrimination laws. The Highland Park (Texas) Department of Public Safety implemented testing in 1991, but no single test adequately evaluated its sworn employees, who are cross-trained and serve as police officers and firefighters. In 2010, the department's fitness experts worked with exercise physiologists from Baylor Heart and Vascular Hospital to develop and evaluate a single test that would be equitable regardless of race/ethnicity, disability, sex, or age >50 years. The new test comprised a series of exercises to assess overall fitness, followed by two sequences of job-specific tasks related to firefighting and police work, respectively. The study group of 50 public safety officers took the test; raw data (e.g., the number of repetitions performed or the time required to complete a task) were collected during three quarterly testing sessions. The statistical bootstrap method was then used to determine the levels of performance that would correlate with 0, 1, 2, or 3 points for each task. A sensitivity analysis was done to determine the overall minimum passing score of 17 points. The new physical fitness test and scoring system have been incorporated into the department's policies and procedures as part of the town's overall employee fitness program.

    The current study evaluated physical activity (PA) level and its associated effects among students in the public network of São Paulo, Brazil. A cross-sectional study was taken using a representative sample of students in São Paulo public school system. International Physical Activity Questionnaire determined PA level. Students who reported at least 300 minutes/week of PA were considered active. The independente variables were: gender, age, body mass index, education, region, recognition of the Agita São Paulo program. The prevalence of regular PA was 71.7%. Males (PR = 1.09, 95% CIs = 1.04 -1.15) at least 17 years old (PR = 1.16, 95% CIs 1.09-1.24) in their 3rd year of high school (PR = 1.20, 95% CIs = 1.12-1.29) who resided in the Midwest region (PR = 1.27, 95% CIs 1.16-1.38) were most likely to be active. Males at least 17 years old in their 3rd year of high school who lived in the Midwest and recognized the Agita São Paulo/Agita Galera program had higher levels of PA. São Paulo students presented a high level of PA. Moreover, males older than 17 years, attending their 3rd year of high school, who lived in the Midwest region, and recognized the Agita São Paulo/Agita Galera program were the most likely to be more active.

    The scope of this study was to analyze the factors associated with the degree of participation in physical activities (DPPA) among students of a public university in the south of Brazil. The Canadian Society for Exercise Physiology Questionnaire was used for the evaluation of DPPA. DPPA was classified as adequate and inadequate. Nutritional status was evaluated based on BMI, classified as normal ( 25 kg/m²). The following socio-demographic variables were analyzed: gender, age group, work, maternal educational level, class period, and marital status. Poisson regression was used to examine the association between DPPA and independent variables, considering p < 0.05. The sample, which was representative of the institution, consisted of 738 students (59.2% males). The prevalence of inadequate physical activity participation was 30.8%. Adjusted analysis showed that female (PR=2.79; 95%CI: 2.10-3.68) and overweight students (PR=1.53; 95%CI: 1.04-2.23) presented a higher risk of inadequate physical activity participation. These findings might be useful for the implementation of health promotion programs in universities, which should pay special attention to female and overweight students in their freshman year.

To date, bystander programs have mainly been compared with no treatment control groups raising questions about what value is added to dating violence prevention by focusing on bystanders. This study compared a single 90-min bystander education program for dating violence prevention with a traditional awareness education program, as well as with a no education control group. Using a quasi-experimental pre-test/post-test design with follow-up at 2 months, a sample of predominately freshmen college students was randomized to either the bystander (n = 369) or traditional awareness (n = 376) dating violence education program. A non-randomized control group of freshmen students who did not receive any education were also surveyed (n = 224). Students completed measures of attitudes, including rape myth acceptance, bystander efficacy, and intent to help as well as behavioral measures related to bystander action and victimization. Results showed that the bystander education program was more effective at changing attitudes, beliefs, efficacy, intentions, and self-reported behaviors compared with the traditional awareness education program. Both programs were significantly more effective than no education. The findings of this study have important implications for future dating violence prevention educational programming, emphasizing the value of bystander education programs for primary dating violence prevention among college students.

    Physical environment influences diet and has been proposed as a determinant of childhood obesity. This cross-sectional study explored physical environment and its associations with diet quality and weight status in a sample of 114 12-year-old children from 4 public schools in the metropolitan area of San Juan, PR. Physical environment was assessed by asking questions regarding the availability and accessibility of healthy and unhealthy foods and food outlets as well as of recreational and sports facilities and equipment. Food intake was determined using a 24-hour diet-recall questionnaire, with the gathered data being used to assess diet quality and calculate the Healthy Eating Index (HEI)-2010. The HEI includes 12 components that are used to determine the compliance of a given diet with federal guidelines. HEI-2010 total score ranges from 0 to 100 and is divided into the following classifications: poor ( 80). Body mass index was computed using measured weight and height and categorized according to the CDC Growth Charts. Thirty-six percent of the participating children were overweight or obese. Nearly 57% had poor diet quality. The lowest HEI-2010 component scores were found for total fruits, whole fruits, total vegetables, whole grains, seafood and plant proteins, and fatty acids. However, diet quality was not associated with weight status or physical environment factors. Compared to the other children in the study, overweight or obese children reported having a significantly (p weight in the children in this sample. However, these same factors did not appear to affect diet quality.

    Full Text Available Background: Physical inactivity and sedentary lifestyles are major risk factors of childhood obesity. This study aimed to measure physical activity (PA levels by accelerometer and Physical Activity Questionnaire for Older Children (PAQ-C among Senegalese school children and the relation with Body Mass Index (BMI and body composition. Methodology: 156 pupils 8–11 years old were randomly selected in four elementary public schools of Dakar. BMI z-score was used to categorize children according to their weight status. PA was measured by PAQ-C in the 156 pupils and by accelerometer (Actigraph GT3X+, Pensacola, FL, USA in a subsample of 42 children. Body composition was determined by deuterium dilution method. Results: PAQ-C results were comparable in the 156 and 42 pupils. The 42 pupils presented a light activity measured by accelerometer, while PAQ-C classified the majority of them (57%; n = 24 in the moderate PA level. Children spent most of their time (min/day in sedentary activities and light activities than in moderate and intense activity levels. Accumulation of 60 min/day Moderate-to-Vigorous Physical Activity (MVPA was achieved by 54.8% (n = 23 of the pupils. MVPA decreased in girls in relation to their body fatness. There was a significant difference in MVPA between boys and girls. Similarly, overweight/obese (45 ± 16 min/day children had lower MVPA than their normal and underweight peers (88 ± 34 and 74 ± 36 min/day, respectively; p = 0.004. Conclusions: The two methods are inconsistent for measuring light and moderate PA levels. Although PAQ-C is an uncomplicated routine method, various activities were not adapted for genuine activities in Senegalese children and therefore needs to be validated in African children.

    2015-12-01

    Using data from focus groups conducted in Colombia, we explore how educated lay audiences faced with scenarios about ancestry and genetics draw on widespread and dominant notions of nation, race and belonging in Colombia to ascribe ancestry to collectivities and to themselves as individuals. People from a life sciences background tend to deploy idioms of race and genetics more readily than people from a humanities and race-critical background. When they considered individuals, people tempered or domesticated the more mechanistic explanations about racialized physical appearance, ancestry and genetics that were apparent at the collective level. Ideas of the latency and manifestation of invisible traits were an aspect of this domestication. People ceded ultimate authority to genetic science, but deployed it to work alongside what they already knew. Notions of genetic essentialism co-exist with the strategic use of genetic ancestry in ways that both fix and unfix race. Our data indicate the importance of attending to the different epistemological stances through which people define authoritative knowledge and to the importance of distinguishing the scale of resolution at which the question of diversity is being posed.

    To describe and compare the type and quality of evidence published in physical therapy (PT) journals during two time periods (2000-2002 vs. 2010-2012) and to explore scientific editors' opinions on changes in the types and quality of articles. A quantitative, longitudinal, retrospective journal review was used to categorize and assess the methodological rigour of items published in four PT journals using the Hedges Project. A quantitative, descriptive, cross-sectional survey explored the opinions of scientific editors. Percentages and frequencies of article types (as defined by the Hedges Project criteria), items passing rigour, and editor responses were calculated. Statistical significance of differences in article type and rigour between the two time periods was determined using Fisher's Exact Test. There was a significant increase in original studies and review articles from 2000-2002 to 2010-2012 (pdesigns, and randomized controlled trials and believed that quality had improved by 2010-2012. From 2000-2002 to 2010-2012, the quality of articles published in PT journals improved and the proportion of original studies and review articles increased.

    Purpose One suggested approach to preventing adolescent dating violence is to prevent behavioral precursors to dating violence, such as bullying. However, no longitudinal study has examined bullying as a behavioral precursor to dating violence. In this study, longitudinal data were used to examine (1) whether direct and indirect bullying perpetration in the sixth grade predicted the onset of physical dating violence perpetration by the eighth grade and (2) whether the associations varied by sex and race/ethnicity of the adolescent. Methods Data were collected in school from sixth graders in three primarily rural counties and then again when students were in the eighth grade. Analyses were conducted with 1,154 adolescents who had not perpetrated dating violence at the sixth-grade assessment. The sample was 47% male, 29% black, and 10% of another race/ethnicity than black or white. Results Direct bullying, defined as hitting, slapping, or picking on another kid in the sixth grade, predicted the onset of physical dating violence perpetration by the eighth grade, controlling for indirect bullying and potential confounders. Although indirect bullying, defined as spreading false rumors and excluding students from friendship groups, was associated with the onset of physical dating violence perpetration in bivariate analyses, it did not predict the onset of physical dating violence when controlling for direct bullying. None of the associations examined varied by sex or race/ethnicity of the adolescents. Conclusions Our findings suggest that efforts targeted at preventing direct bullying may also prevent the onset of physical dating violence. PMID:24768162

    Domestic violence is a paramount issue in society today. One component of this is the violence associated with dating and interpersonal relationships in the teen years. Current research demonstrates that a significant percentage of teens have experienced some degree of physical, sexual, or emotional abuse from a dating partner. Pediatric nurses may interface with teens before, during, and after violent episodes. It is important for nurses to know the definitions of dating violence and rape, data about the incidence and prevalence of this issue, risk factors for violence in intimate relationships, dating violence myths, and the potential impact of youth dating violence. Youth perceptions and current research must be analyzed to frame current and potential interventions to reduce teen dating violence. Pediatric nurses have an integral role in counseling teens, ensuring youth safety, and preventing violence in the adolescent years.

Moreover, ideograms can simplify the often cumbersome notation used in the fields of Physics and physical Chemistry. Nonetheless only a few ideograms- like and - have been defined to date. In this work we propose that the scientific community follows the example of Mathematics—as well as that of oriental languages—and bestows a more important role upon ideograms. To support this thesis we propose ideograms for essential concepts in Physics and Chemistry. They are designed to be intuitive, and their goal is to make equations easier to read and understand.

    Three decades of rapid economic development in China have not only benefited millions of Chinese by improving their living standards but have also dramatically increased the number of people who are part of the country’s aging population. However, economic growth has not been accompanied by sufficient attention given to important public health issues, including an increase in the incidence of chronic diseases and a decline in physical activity (PA) that comes with an aging population. The rapid growth in China’s older population will soon exert an impact on the nation’s economy, population health status, and health behaviors, and will increase stress on its healthcare system. This review article provides a broad perspective on the impact of rapid economic development, industrialization, and urbanization on health-related behaviors, with a specific focus on PA among older adults. Specifically, the article offers an overview of the demographic context, significant public health challenges, evidence on PA and exercise interventions, and knowledge gaps and future directions for research.

    Scientists, policymakers and science communicators generally work from an assumption that science communication, or 'outreach', is good and often work from a primarily practice-based knowledge. Meanwhile, the science, technology and society (STS) community, which is strongly grounded in theory and critical analysis, is critical of certain aspects of science communication, particularly in controversial areas of science. Unfortunately, these two groups rarely speak to each other, and when they do they don't necessarily understand one another. Much of this confusion relates to different assumptions around the goals of science communication, as well as differing understandings of the various roles and responsibilities in both science and society. The result, unfortunately, is a lack of science communication practice and theory informing each other. This research is a collaboration between a scientist communicator with a positive attitude to outreach, who works in the field of climate change; a political theorist with expertise in public dialogue around biotechnology and has been critical of motivations for engaging the public with science; and a science historian and science communicator who has uncovered surprising and significant changes in public attitudes towards nuclear science and technology in New Zealand. By exploring our understanding of science communication through these diverse disciplinary lenses, and considering three fields of science that are or have been highly controversial for different reasons, we have identified several subtleties in both the politics of communicating different areas of controversial science, and the difficulties of finding a common language across social and physical sciences. We conclude that greater reflexivity about our own roles and assumptions, and increased efforts at enhanced understanding across disciplines, is central to applying the theories in STS to the practice of communication by scientists.

    Intervention programs that change environments have the potential for greater population impact on obesity compared to individual-level programs. We began a cluster randomized, multi-component multi-level intervention to improve weight, diet, and physical activity among low-socioeconomic status public housing residents. Here we describe the rationale, intervention design, and baseline survey data. After approaching 12 developments, ten were randomized to intervention (n=5) or assessment-only control (n=5). All residents in intervention developments are welcome to attend any intervention component: health screenings, mobile food bus, walking groups, cooking demonstrations, and a social media campaign; all of which are facilitated by community health workers who are residents trained in health outreach. To evaluate weight and behavioral outcomes, a subgroup of female residents and their daughters age 8-15 were recruited into an evaluation cohort. In total, 211 households completed the survey (RR=46.44%). Respondents were Latino (63%), Black (24%), and had ≤ high school education (64%). Respondents reported ≤2 servings of fruits & vegetables/day (62%), visiting fast food restaurants 1+ times/week (32%), and drinking soft drinks daily or more (27%). The only difference between randomized groups was race/ethnicity, with more Black residents in the intervention vs. control group (28% vs. 19%, p=0.0146). Among low-socioeconomic status urban public housing residents, we successfully recruited and randomized families into a multi-level intervention targeting obesity. If successful, this intervention model could be adopted in other public housing developments or entities that also employ community health workers, such as food assistance programs or hospitals.

    Date palm is one of the oldest trees cultivated by man. In the folk-lore, date fruits have been ascribed to have many medicinal properties when consumed either alone or in combination with other herbs. Although, fruit of the date palm served as the staple food for millions of people around the world for several centuries, studies on the health benefits are inadequate and hardly recognized as a healthy food by the health professionals and the public. In recent years, an explosion of interest in the numerous health benefits of dates had led to many in vitro and animal studies as well as the identification and quantification of various classes of phytochemicals. On the basis of available documentation in the literature on the nutritional and phytochemical composition, it is apparent that the date fruits are highly nutritious and may have several potential health benefits. Although dates are sugar-packed, many date varieties are low GI diet and refutes the dogma that dates are similar to candies and regular consumption would develop chronic diseases. More investigations in these areas would validate its beneficial effects, mechanisms of actions, and fully appreciate as a potential medicinal food for humans all around the world. Therefore, in this review we summarize the phytochemical composition, nutritional significance, and potential health benefits of date fruit consumption and discuss its great potential as a medicinal food for a number of diseases inflicting human beings.

    2016-10-05

    Although multiple forms (i.e., physical, threatening, psychological, sexual, and relational abuse) and patterns (i.e., perpetration and victimization) of violence can co-occur, most existing research examines these experiences individually. Thus, the purpose of this study is to investigate: (1) homogenous subgroups based on victimization and perpetration of multiple forms of teen dating violence; (2) predictors of membership in these subgroups; and (3) mental health consequences associated with membership in each subgroup. Nine hundred eighteen adolescents in the 9(th) or 10(th) grade at seven public high schools in Texas participated in the survey (56 % female, White: 30 %, Hispanic: 32 %, African American: 29 %, others: 9 %). A three-step latent class analysis was employed. Five latent teen dating violence classes were identified: (1) nonviolence; (2) emotional/verbal abuse; (3) forced sexual contact; (4) psychological + physical violence; and (5) psychological abuse. Females, African Americans, and youth who had higher acceptance of couple violence scores and whose parents had less education were more likely to members of dating violence classes compared with the nonviolence class. Adolescents who experienced multiple types of dating violence reported greater mental health concerns. Prevention programs may benefit by identifying the homogenous subgroups of teen dating violence and targeting adolescent teen dating violence accordingly.

Until the 1980s, this was quite uncontroversial as the linguistic findings largely confirmed...... the chronology of the texts established by other means: the Hebrew of Genesis-2 Kings was judged to be early and that of Esther, Daniel, Ezra, Nehemiah, and Chronicles to be late.

In the first trial, Tunisian Deglet date stones were used and in the second one, stones were the waste product of an Italian distillery. One-day-old Arbor Acres chickens were cage reared and fed for 6 weeks on 4 experimental diets, which were formulated to be isonitrogenous and isocaloric and differed in cereal component (maize or low tannin sorghum and in inclusion level (0 or 10 % of ground date stones. Birds ' performances were slightly different in the two trials, but overall results indicate that date stones are suitable for use in broiler's feeding under such conditions.

  14. Radiocarbon dating of terrestrial carbonates

    Pigati, Jeffrey S.; Rink, W. Jack; Thompson, Jeroen

    2014-01-01

    Terrestrial carbonates encompass a wide range of materials that potentially could be used for radiocarbon (14C) dating. Biogenic carbonates, including shells and tests of terrestrial and aquatic gastropods, bivalves, ostracodes, and foraminifera, are preserved in a variety of late Quaternary deposits and may be suitable for 14C dating. Primary calcareous deposits (marls, tufa, speleothems) and secondary carbonates (rhizoliths, fracture fill, soil carbonate) may also be targeted for dating when conditions are favorable. This chapter discusses issues that are commonly encountered in 14C dating of terrestrial carbonates, including isotopic disequilibrium and open-system behavior, as well as methods used to determine the reliability of ages derived from these materials. Recent methodological advancements that may improve the accuracy and precision of 14C ages of terrestrial carbonates are also highlighted.

    2009-11-01

    1. Physics competitions: aims and realizations One aim of physics competitions is to increase the interest of young students, primarily at upper secondary level, to physics and natural sciences in general. A competition has motivational aspects known usually from sports events or games—comparing one's own ability with others, of course with the desire to be better and to win. If competitions reach nationwide and even international levels, additional stimulation is created. Competitions provide greatest attraction to possible winners, to the group of gifted people in a particular field. This implies that science contests are excellent tools for the promotion of talented students. Traditional teaching has been shown to have problems in supporting this group of students. Very often teachers are overstretched with the demands of teaching both low- and high-level students. Extracurricular activities are therefore a good chance to relieve the teacher, and to give talented students the opportunity for appropriate training and challenge. The competitions, however, have a broader impact and address more young people than one might guess from the statements above. Training courses and selection at school level give a larger group of students extra and, to some extent, complimentary education in physics. The degree of complexity of the tasks corresponds very often to the standards of the next level of education in the school system. Interestingly, many physics competitions have their origin in countries beyond the former Iron Curtain. They started as regional and national tournaments, were joined by neighbouring countries and have grown, in some cases, to events with participants from more than 80 countries. Although the features mentioned above are common to the different competitions, there are distinct differences between them [1]. The International Physics Olympiad (IPhO) is the oldest international physics competition for students at upper secondary level [2]. It dates

    In this paper, radiocarbon dating of paintings using minimal sample sizes has been investigated, in an effort to address the problem of limited access to sample material in paintings. 14C analyses were conducted on signed and dated paintings from two Swiss artists of the twentieth century. The selected paintings dated from the 1930s and 1960s, provided the opportunity to evaluate the dating accuracy on paintings realized before and after 1950 AD when the 14C bomb peak was created, as a result of the nuclear tests conducted in the 1950/1960s. The work focused on the one hand on minimizing the size of the canvas sample required for accelerator mass spectrometer radiocarbon measurement on the gas ion source of the MICADAS and, on the other hand, on testing the possibility of dating the organic binder of the paint. Following careful characterization of the paint composition by X-ray fluorescence spectroscopy, Fourier transformed infrared spectroscopy, and Raman spectroscopy, paints containing no other carbon source than the natural organic binder were identified and dated.

    Given that emotional health is a critical component of healthy aging, we undertook a systematic literature review to assess whether current interventions can positively affect older adults' emotional health. A national panel of health services and mental health researchers guided the review. Eligibility criteria included community-dwelling older adult (aged ≥ 50 years) samples, reproducible interventions, and emotional health outcomes, which included multiple domains and both positive (well-being) and illness-related (anxiety) dimensions. This review focused on three types of interventions - physical activity, social support, and skills training - given their public health significance and large number of studies identified. Panel members evaluated the strength of evidence (quality and effectiveness). In all, 292 articles met inclusion criteria. These included 83 exercise/physical activity, 25 social support, and 40 skills training interventions. For evidence rating, these 148 interventions were categorized into 64 pairings by intervention type and emotional health outcome, e.g., strength training targeting loneliness or social support to address mood. 83% of these pairings were rated at least fair quality. Expert panelists found sufficient evidence of effectiveness only for skills training interventions with health outcomes of decreasing anxiety and improving quality of life and self-efficacy. Due to limitations in reviewed studies, many intervention-outcome pairings yielded insufficient evidence. Skills training interventions improved several aspects of emotional health in community-dwelling older adults, while the effects for other outcomes and interventions lacked clear evidence. We discuss the implications and challenges in moving forward in this important area.

    OBJECTIVES: An earlier report described desirable 1-month follow-up effects of the Safe Dates program on psychological, physical, and sexual dating violence. Mediators of the program-behavior relationship also were identified. The present report describes the 1-year follow-up effects of the Safe Dates program. METHODS: Fourteen schools were in the randomized experiment. Data were gathered by questionnaires in schools before program activities and 1 year after the program ended. RESULTS: The short-term behavioral effects had disappeared at 1 year, but effects on mediating variables such as dating violence norms, conflict management skills, and awareness of community services for dating violence were maintained. CONCLUSIONS: The findings are considered in the context of why program effects might have decayed and the possible role of boosters for effect maintenance. PMID:11029999

    Dating violence among U.S. adolescents is a substantial concern. Previous research indicates that Latino youth are at increased risk of dating violence victimization. This secondary data analysis examined the prevalence of physical and sexual dating violence victimization among subgroups of Latino adolescents and associations of parent communication, parent caring, and dating violence victimization using data from the 2010 Minnesota Student Survey (N = 4,814). Parallel analyses were conducted for Latino-only and multiple-race Latino adolescents, stratified by gender. Multivariate logistic regression models tested associations between race/ethnicity, parent communication, perceived parent caring, and adolescent dating violence experiences. Overall, 7.2% to 16.2% of Latinos reported physical or sexual dating violence. Both types of dating violence were more prevalent among multiple-race Latinos than among Latino-only adolescents, with prevalence rates highest among multiple-race Latino females (19.8% and 19.7% for physical and sexual dating violence victimization, respectively). In multivariate models, perceived parent caring was the most important protective factor against physical and sexual dating violence among males and females. High levels of mother and father communication were associated with less physical violence victimization among males and females and with less sexual violence victimization among females. Results highlight the importance of parent communication and parent caring as buffers against dating violence victimization for Latino youth. These findings indicate potential for preventive interventions with Latino adolescents targeting family connectedness to address dating violence victimization.

  16. ESR dating of fault rocks

    Energy Technology Data Exchange (ETDEWEB)

    Lee, Hee Kwon [Kangwon National Univ., Chuncheon (Korea, Republic of)

    2002-03-15

    Past movement on faults can be dated by measurement of the intensity of ESR signals in quartz. These signals are reset by local lattice deformation and local frictional heating on grain contacts at the time of fault movement. The ESR signals then trow back as a result of bombardment by ionizing radiation from surrounding rocks. The age is obtained from the ratio of the equivalent dose, needed to produce the observed signal, to the dose rate. Fine grains are more completely reset during faulting, and a plot of age vs grain size shows a plateau for grains below critical size : these grains are presumed to have been completely zeroed by the last fault activity. We carried out ESR dating of fault rocks collected from the Yangsan fault system. ESR dates from the this fault system range from 870 to 240 ka. Results of this research suggest that long-term cyclic fault activity continued into the pleistocene.

    The art`s additional value, unequalled by traditionally recognised artefacts, is its permanent pictorial documentation presenting a `window` into the otherwise intangible elements of perceptions, vision and mind of pre-historic cultures. Unfortunately it`s potential in establishing Kimberley archaeological `big picture` still remains largely unrecognised. Some of findings of the Kimberley Rock Art Dating Project, using AMS and optical stimulated luminescence (OSL) dating techniques, are outlined. It is estimated that these findings will encourage involvement by a greater diversity of specialist disciplines to tie findings into levels of this art sequence as a primary reference point. The sequence represents a sound basis for selecting specific defined images for targeting detailed studies by a range of dating technique. This effectively removes the undesirable ad hoc sampling of `apparently old paintings`; a process which must unavoidably remain the case with researchers working on most global bodies of rock art.

    2014-05-01

    Media attention and the literature on lesbian, gay, and bisexual youth overwhelmingly focus on violence involving hate crimes and bullying, while ignoring the fact that vulnerable youth also may be at increased risk of violence in their dating relationships. In this study, we examine physical, psychological, sexual, and cyber dating violence experiences among lesbian, gay, and bisexual youth--as compared to those of heterosexual youth, and we explore variations in the likelihood of help-seeking behavior and the presence of particular risk factors among both types of dating violence victims. A total of 5,647 youth (51 % female, 74 % White) from 10 schools participated in a cross-sectional anonymous survey, of which 3,745 reported currently being in a dating relationship or having been in one during the prior year. Results indicated that lesbian, gay, and bisexual youth are at higher risk for all types of dating violence victimization (and nearly all types of dating violence perpetration), compared to heterosexual youth. Further, when looking at gender identity, transgender and female youth are at highest risk of most types of victimization, and are the most likely perpetrators of all forms of dating violence but sexual coercion, which begs further exploration. The findings support the development of dating violence prevention programs that specifically target the needs and vulnerabilities of lesbian, gay, and bisexual youth, in addition to those of female and transgender youth.

    Full Text Available The topic of this issue is PUBLIC SPACES. It is familiar and clear to every citizen. The streets and courtyards as childhood experiences remain with us forever. And these are the places where we come with our parents at weekends, where we meet friends, where we have dates and where we already come for a walk with our children.The history of public spaces is long and captivating. It was the main city squares where the most important events took place in history. The Agoras of Ancient Greece and the Roman Forums, the squares of Vatican, Paris and London, Moscow and Saint Petersburg… Greve, Trafalgar, Senate, Palace, Red, Bolotnaya – behind every name there is life of capitals, countries and nations.Public spaces, their shapes, image and development greatly influence the perception of the city as a whole. Both visitors and inhabitants can see in public spaces not only the visage but the heart, the soul and the mind of the city.Unfortunately, sometimes we have to prove the value of public spaces and defend them from those who consider them nothing but a blank space, nobody’s land destined for barbarous development.What should happen to make citizens perceive public spaces as their own and to make authorities consider development and maintenance of squares and parks their priority task against the  background of increasing competition between cities and the fight for human capital? Lately they more often say about “a high-quality human capital”. And now, when they say “the city should be liveable” they add “for all groups of citizens, including the creative class”.

    2009-01-01

    For the waiting world, and indeed for most of us here at CERN, ‘the LHC schedule’ simply means the date that the LHC will restart - and we only take notice when that end-date changes. But in fact the schedule is a constantly evolving intricate document coordinating all the repairs, consolidation and commissioning in every part of the machine. So, what actually goes on behind the scenes in timing and planning all the work on one of the most complex scientific instruments ever built?

    Theory and research suggest that there may be significant heterogeneity in the development, manifestation, and consequences of adolescent dating violence that is not yet well understood. The current study contributed to our understanding of this heterogeneity by identifying distinct patterns of involvement in psychological, physical, and sexual dating violence victimization and perpetration in a sample of Latino youth (n = 201; M = 13.87 years; 42% male), a group that is understudied, growing, and at high risk for involvement in dating violence. Among both boys and girls, latent class analyses identified a three-class solution wherein the largest class demonstrated a low probability of involvement in dating violence across all indices ("uninvolved"; 56% of boys, 64% of girls) and the smallest class demonstrated high probability of involvement in all forms of dating violence except for sexual perpetration among girls and physical perpetration among boys ("multiform aggressive victims"; 10% of boys, 11% of girls). A third class of "psychologically aggressive victims" was identified for which there was a high probability of engaging and experiencing psychological dating violence, but low likelihood of involvement in physical or sexual dating violence (34% of boys, 24% of girls). Cultural (parent acculturation, acculturation conflict), family (conflict and cohesion) and individual (normative beliefs, conflict resolution skills, self-control) risk and protective factors were associated with class membership. Membership in the multiform vs. the uninvolved class was concurrently associated with emotional distress among girls and predicted emotional distress longitudinally among boys. The results contribute to understanding heterogeneity in patterns of involvement in dating violence among Latino youth that may reflect distinct etiological processes.

    2009-01-01

    This self-contained introduction discusses the evolution of the notion of coherent states, from the early works of Schrödinger to the most recent advances, including signal analysis. An integrated and modern approach to the utility of coherent states in many different branches of physics, it strikes a balance between mathematical and physical descriptions.Split into two parts, the first introduces readers to the most familiar coherent states, their origin, their construction, and their application and relevance to various selected domains of physics. Part II, mostly based on recent original results, is devoted to the question of quantization of various sets through coherent states, and shows the link to procedures in signal analysis.

  8. Current topics in ESR dating

    Energy Technology Data Exchange (ETDEWEB)

    Skinner, Anne R., E-mail: Anne.R.Skinner@williams.edu [Williams College, Williamstown, MA (United States)

    After over 25 years, the use of electron spin resonance (ESR) is well-established in dating sites of geological, paleontological and archaeological interest. Like any scientific technique, there have been changes in understanding and in methodology. Improvements have not, however, changed the observation that external dose calculations are still a significant source of uncertainty in ages. Examples from Europe, Africa and the Americans illustrate this point. For Pradayrol Cave (France), the occupation age, 330 ka, is unchallenged, making this the oldest known Neanderthal site in France. For Roc de Marsal, also in France, on the other hand, discrepancies between TL and sedimentary dose rates imply substantial differences in interpretation. In the Western Egyptian Desert, where artifacts and datable material are not well-correlated, the dating results show consistency with expectations based on global climate change, even in deflated sites. Climate change is also the question in geological studies in the Bahamas where, despite concerns about cosmic dose history, ESR dates confirm other evidence for sea level changes. We show that an uncertain age is not the same as an impossible one.

  9. ESR dating of fault rocks

    Energy Technology Data Exchange (ETDEWEB)

    Lee, Hee Kwon [Kangwon National Univ., Chuncheon (Korea, Republic of)

    2003-02-15

    Past movement on faults can be dated by measurement of the intensity of ESR signals in quartz. These signals are reset by local lattice deformation and local frictional heating on grain contacts at the time of fault movement. The ESR signals then grow back as a result of bombardment by ionizing radiation from surrounding rocks. The age is obtained from the ratio of the equivalent dose, needed to produce the observed signal, to the dose rate. Fine grains are more completely reset during faulting, and a plot of age vs. grain size shows a plateau for grains below critical size; these grains are presumed to have been completely zeroed by the last fault activity. We carried out ESR dating of fault rocks collected near the Gori nuclear reactor. Most of the ESR signals of fault rocks collected from the basement are saturated. This indicates that the last movement of the faults had occurred before the Quaternary period. However, ESR dates from the Oyong fault zone range from 370 to 310 ka. Results of this research suggest that long-term cyclic fault activity of the Oyong fault zone continued into the Pleistocene.

    To identify the basic competencies and contents related to public health to be included in degree programs according to the perspective of lecturers from various Spanish universities. In the context of the Second Workshop on Public Health Contents in Degree Programs (Mahon, 19 to 20 September 2012), 20 lecturers from different Spanish universities were distributed in five working groups. The lecturers had been selected from the instructional guides on public health and epidemiology published on the web sites of the Rectors' Conference of Spanish Universities. Each group worked on a degree program and the results were discussed in plenary sessions. The activities and competencies related to the three basic functions of public health were identified in all degree programs. Most of the professional competencies identified were related to the function of «assessment of population health needs». The contents proposed by the working groups related to epidemiology, basic concepts in public health, public health intervention, health management, and health policy. The main common topics among the degrees concerned the first three contents. Public health professional competencies and contents were identified in the degree programs examined. These results may serve as a starting point for a more detailed review of public health programs across degree levels and the search for a consensus on the common content that should be included in each of them.

  13. Engaging adolescent girls in transactional sex through compensated dating.

    Science.gov (United States)

    Cheung, Chau-Kiu; Jia, Xinshan; Li, Jessica Chi-Mei; Lee, Tak-Yan

    2016-10-01

    Transactional sex through so-called compensated dating in adolescent girls is a problem in need of public concern. Compensated dating typically involves the use of information communication technology to advertise, search, bargain, and eventually arrange for transactional sex. The technology enables the sexual partners to maintain privacy and secrecy in transactional sex. Such secrecy necessitates the girls' disclosure about their life experiences in order to address the concern. The disclosure is the focus of the present qualitative study of 27 girls practicing the dating in Hong Kong, China. Based on the disclosure, the study presents a grounded theory that epitomizes engagement in compensated dating by referential choice. Such a referential choice theory unravels that choice with reference to the family push and social norms sustains the engagement. Meanwhile, the choice rests on expectancy and reinforcement from experiential learning about compensated dating. The theory thus implies ways to undercut the engagement through diverting the referential choice of the dating. Copyright © 2016 The Foundation for Professionals in Services for Adolescents.

  14. Tectonic calibrations in molecular dating

    Institute of Scientific and Technical Information of China (English)

    Ullasa KODANDARAMAIAH

    2011-01-01

    Molecular dating techniques require the use of calibrations, which are usually fossil or geological vicariance-based.Fossil calibrations have been criticised because they result only in minimum age estimates. Based on a historical biogeographic perspective, Ⅰ suggest that vicariance-based calibrations are more dangerous. Almost all analytical methods in historical biogeography are strongly biased towards inferring vicariance, hence vicariance identified through such methods is unreliable. Other studies, especially of groups found on Gondwanan fragments, have simply assumed vicariance. Although it was previously believed that vicariance was the predominant mode of speciation, mounting evidence now indicates that speciation by dispersal is common, dominating vicariance in several groups. Moreover, the possibility of speciation having occurred before the said geological event cannot be precluded. Thus, geological calibrations can under- or overestimate times, whereas fossil calibrations always result in minimum estimates. Another major drawback of vicariant calibrations is the problem of circular reasoning when the resulting estimates are used to infer ages of biogeographic events. Ⅰ argue that fossil-based dating is a superior alternative to vicariance, primarily because the strongest assumption in the latter, that speciation was caused by the said geological process, is more often than not the most tenuous. When authors prefer to use a combination of fossil and vicariant calibrations, one suggestion is to report results both with and without inclusion of the geological constraints. Relying solely on vicariant calibrations should be strictly avoided.

  17. Retrospective Birth Dating of Cells

    Energy Technology Data Exchange (ETDEWEB)

    L.Spalding, K; Bhardwaj, R D; Buchholz, B A; Druid, H; Frisen, J

    2005-04-19

    The generation of cells in the human body has been difficult to study and our understanding of cell turnover is limited. Extensive testing of nuclear weapons resulted in a dramatic global increase in the levels of the isotope {sup 14}C in the atmosphere, followed by an exponential decrease after the test ban treaty in 1963. We show that the level of {sup 14}C in genomic DNA closely parallels atmospheric levels, and can be used to establish the time point when the DNA was synthesized and cells were born. We use this strategy to determine the age of cells in the cortex of the adult human brain, and show that whereas non-neuronal cells are exchanged, occipital neurons are as old as the individual, supporting the view that postnatal neurogenesis does not take place in this region. Retrospective birth dating is a generally applicable strategy that can be used to measure cell turnover in man under physiological and pathological conditions.

  19. Blind-date Conversation Joining

    Directory of Open Access Journals (Sweden)

    Luca Cesari

    2013-07-01

    Full Text Available We focus on a form of joining conversations among multiple parties in service-oriented applications where a client may asynchronously join an existing conversation without need to know in advance any information about it. More specifically, we show how the correlation mechanism provided by orchestration languages enables a form of conversation joining that is completely transparent to clients and that we call 'blind-date joining'. We provide an implementation of this strategy by using the standard orchestration language WS-BPEL. We then present its formal semantics by resorting to COWS, a process calculus specifically designed for modelling service-oriented applications. We illustrate our approach by means of a simple, but realistic, case study from the online games domain.

  20. Weight Perceptions, Misperceptions, and Dating Violence Victimization Among U.S. Adolescents

    OpenAIRE

    Farhat, Tilda; Haynie, Denise; Summersett-Ringgold, Faith; Brooks-Russell, Ashley; Iannotti, Ronald J

    2014-01-01

    Dating violence is a major public health issue among youth. Overweight/obese adolescents experience peer victimization and discrimination and may be at increased risk of dating violence victimization. Furthermore, given the stigma associated with overweight/obesity, perceptions and misperceptions of overweight may be more important than actual weight status for dating violence victimization. This study examines the association of three weight indices (weight status, perceived weight, and weig...

    OBJECTIVE: Physical exercise helps to prevent cardiovascular disorders. Campaigns promoting exercise have taken many people to the parks of our city. The most appropriate exercise for preventing cardiovascular disorders is the aerobic modality; inappropriate exercise acutely increases cardiovascular risk, especially in individuals at higher risk. Therefore, assessing the cardiovascular risk of these individuals and their physical activities is of practical value. METHODS: In the Parque Fernan...

  7. New Radiocarbon Dates on Upper Mid-West Proboscideans: Determining Date Robustness

    Science.gov (United States)

    Hodgins, G.; Widga, C.; Lengyel, S. N.; Saunders, J.; Walker, J. D.

    2013-12-01

    With the objective of refining the picture of Megafaunal extinction patterns in the upper Midwest in the terminal Pleistocene, we have assembled for radiocarbon dating specimens from more than 80 distinct Mammut and Mammuthus remains from potentially late sites. So far, we have measurements for 65 bones, tusks and teeth, nearly double the extant number of published dates . These new specimens were all from museums rather than excavation sites, and 60% were known to be coated with a consolidant. The predominant consolidant was Butvar B-76, however shellac, Elmer's Glue, Glyptol were also noted in the conservation records, or deduced from knowledge of a particular museum's practices. Given the objective of the project is to identify extinction patterns, coupled with the wide prevalence of consolidants amongst the specimen set, it was imperative that testing be carried out to confirm that radiocarbon laboratory protocols removed the consolidants, so that ultimately the dates can be considered robust. To this end, key specimens were dated three times using different sample preparation protocols. These were 1) a solvent extraction followed by a modified Longin-plus -Base continuous flow collagen extraction method used in the NSF-Arizona AMS facility, 2) the solvent/modified Longin method plus ultrafiltration, and 3) solvent/modified Longin method plus hydroxyproline single amino acid dating. Among the specimens subjected to triplicate testing were some of the youngest late Wisconsin proboscidean specimens from the Upper Midwest Region. The data reveal general agreement between the different protocols, and suggested either limited penetration of consolidants into the specimens, or that the standard laboratory cleaning protocols were sufficient to remove traces from deep within bone, tooth or tusk tissue. The preservation of each specimen, recorded in terms of collagen content, C/N ratio and stable isotope values, indicated that most were actually well preserved, implying

  17. Cannabis use and dating violence among college students: A call for research.

    Science.gov (United States)

    Shorey, Ryan C; Haynes, Ellen; Strauss, Catherine; Temple, Jeff R; Stuart, Gregory L

    2017-01-01

    Dating violence is a serious and prevalent problem on college campuses. Although there is a robust literature documenting that alcohol use is consistently associated with increased risk for perpetrating dating violence, little research has examined the role of cannabis in dating violence perpetration. With increasing legalisation of cannabis throughout the world, it is imperative to understand what role, if any, cannabis may play in the important public health problem of dating violence. In this commentary, we discuss the current state of the research on cannabis and dating violence and suggest avenues for additional research in this area. It is critical that we conduct methodologically sound research on the association between cannabis and dating violence so that we can understand what role, if any, cannabis exerts on this important problem.

    2012-01-01

    We examined the hypothesis that family, peer and neighborhood violence would moderate relations between heavy alcohol use and adolescent dating violence perpetration such that relations would be stronger for teens in violent contexts. Random coefficients growth models were used to examine the main and interaction effects of heavy alcohol use and four measures of violence (family violence, friend dating violence, friend peer violence and neighborhood violence) on levels of physical dating viol...
