    A variety of methods are available for defining undernutrition (thinness/underweight/under-fat) and overnutrition (overweight/obesity/over-fat). The extent to which these definitions agree is unclear. The present cross-sectional study aimed to assess agreement between widely used methods of assessing nutritional status in children and adolescents, and to examine the benefit of body composition estimates. The main objective of the cross-sectional study was to assess underweight, overweight and obesity using four methods: (i) BMI-for-age using WHO (2007) reference data; (ii) BMI-for-age using Cole et al. and International Obesity Taskforce cut-offs; (iii) weight-for-age using the National Centre for Health Statistics/WHO growth reference 1977; and (iv) body fat percentage estimated by bio-impedance (body fat reference curves for children of McCarthy et al., 2006). Comparisons were made between methods using weighted kappa analyses. Subjects Individuals (n 1519) in three age groups (school grade 1, mean age 7 years; grade 5, mean age 11 years; grade 9, mean age 15 years). Results In boys, prevalence of unhealthy weight status (both under- and overnutrition) was much higher at all ages with body fatness measures than with simple anthropometric proxies for body fatness; agreement between fatness and weight-based measures was fair or slight using Landis and Koch categories. In girls, prevalence of unhealthy weight status was also higher with body fatness than with proxies, although agreement between measures ranged from fair to substantial. Methods for defining under- and overnutrition should not be considered equivalent. Weight-based measures provide highly conservative estimates of unhealthy weight status, possibly more conservative in boys. Simple body composition measures may be more informative than anthropometry for nutritional surveillance of children and adolescents

    Get PDF
    In recent years, research examining new sport teams has emerged. A total of ten senior sales and market executives were interviewed from recent expansion teams from Major League Soccer (MLS) to analyze team brand development for this study due to its continued expansion efforts across North America and the fact that the MLS continues to compete for market share against other ā€œBig Fourā€ sport teams in their respective cities. Utilizing content analysis, findings from this study identified four themes when developing a new team brand. These themes were Market Research, Soccer Culture, Brand Associations, and Supporter-Led Initiatives. Practical implications are provided for developing a new team brand

    Sport Management Internship Quality and the Development of Political Skill: A Conceptual Model

    Get PDF
    Internships are a key component of sport organizations and the sport management curriculum. Due to the vastness of internships both in academia and the sport profession, it is imperative to understand the effectiveness of internships for both the organization and the intern. While previous research has focused on quality control, the agencyā€™s perspective of internships, the studentā€™s perspective, and how to link the theory to practice, scholars have yet to examine the effects of sport management internships on the development of essential professional skills and/or attributes. Given the political nature of obtaining and keeping a job in the sport business, the purpose of this paper is to propose a conceptual model that allows the effectiveness of a sport management internship to be evaluated according to its effect on the political skill of interns. Understanding the internship as one component of the sport management curricula, the conceptual model links sport management studentsā€™ developmental experiences, and internship quality to the development of political skill, and three secondary outcomes (i.e., domain-specific self-efficacy, sport industry identification, and future employment intentions). In doing so a comprehensive method for evaluating the effectiveness of internships that prioritizes the studentā€™s growth is offered

    Refactoring for introducing and tuning parallelism for heterogeneous multicore machines in Erlang

    This research has been generously supported by the European Union Framework 7 Para-Phrase project (IST-288570), EU Horizon 2020 projects RePhrase (H2020-ICT-2014-1), agreement number 644235; Teamplay (H2020-ICT 2017-1) agreement number 779882, and EPSRC Discovery, EP/P020631/1. EU COST Action IC1202: Timing Analysis On Code-Level (TACLe), and by a travel grant from EU HiPEAC.This paper presents semiā€automatic software refactorings to introduce and tune structured parallelism in sequential Erlang code, as well as to generate code for running computations on GPUs and possibly other accelerators. Our refactorings are based on the lapedo framework for programming heterogeneous multiā€core systems in Erlang. lapedo is based on the PaRTE refactoring tool and also contains (1) a set of hybrid skeletons that target both CPU and GPU processors, (2) novel refactorings for introducing and tuning parallelism, and (3) a tool to generate the GPU offloading and scheduling code in Erlang, which is used as a component of hybrid skeletons. We demonstrate, on four realistic useā€case applications, that we are able to refactor sequential code and produce heterogeneous parallel versions that can achieve significant and scalable speedups of up to 220 over the original sequential Erlang program on a 24ā€core machine with a GPU.PostprintPeer reviewe

    Full Bloom: Diegetic UI for musical phrases in virtual reality

    Get PDF
    We propose a novel system for communicating musical note pitch and sequence information to users within a virtual reality environment. Our approach utilizes ā€˜Blooms,ā€™ objects that resemble flowers with various petal arrangements. These formations, when constructed in view of users, act as diegetic, user-parsable encodings of their inputs. Blooms exist within the virtual space as simulated physics objects that collectively serve the role of a user interface

    Perceptions of the barriers to effective inclusion in one primary school: Voices of teachers and teaching assistants

    Get PDF
    This study examined the barriers to inclusion in one primary school in the north of England. Qualitative data were collected from teachers and teaching assistants through the use of a focus group. The evidence suggested that practices within the school were varied and ranged from highly inclusive to highly exclusive. Some teachers worked in good faith to develop effective inclusion for learners with special educational needs. Conversely, other teachers displayed negative attitudes towards these pupils and this impacted negatively on the school's commitment to inclusion. Lack of funding, resources and training were identified as key barriers to inclusion. Parental resistance to inclusion was also evident within the context of this school and there was a strong feeling that the inclusion agenda was problematic in the context of the standards agenda. Despite these issues there was a strong sense that practitioners should be willing to commit to the principles of inclusive education and the study considers some ways in which schools can advance their practice in this respect. Within this study the term ā€˜practitionerā€™ is used to represent teachers and teaching assistants

    Media involvement in the Missing and Murdered Indigenous Women/Girls (MMIWG) epidemic

    Get PDF
    The Missing and Murdered Indigenous Women and Girls (MMIWG) epidemic was created to raise awareness about the high rates of violence against Indigenous women and girls. Media coverage for MMIWG survivors in United States and Canada remains lacking, as mainstream reporting is almost non-existent for Indigenous women and girls. Out of 506 MMIWG cases, only one-quarter were reported by local, regional, or national media (UIHI, 2018). These victims are commonly overshadowed by other cases comprised of non-Hispanic White (NHW) women who go missing. In Canada's local press, missing and murdered NHW women were referred to 511 times compared to 82 times for Indigenous women (Gilchrist, 2010). Further, Indigenous women and girls who are abuse survivors and are reported in the media are usually depicted in negative and stereotypical contexts like sex-work and criminal behavior, which is in stark contrast to their NHW counterparts. However, advocates of the MMIWG epidemic have created increased social media exposure by sharing survivors' stories. During an 11-month study using data from Twitter, over 107,400 tweets included #MMIW and #MMIWG; these hashtags were used to shift perceptions of Indigenous women/girls and to apply political pressure to increasing news coverage of current rates of MMIWG (Moeke-Pickering et al., 2018). Increasing Indigenous representation and exposure via the media creates the opportunity to generate discussions, encourage activism, and ultimately, promote systemic-level changes for justice among Indigenous women and girls. The purpose of this poster presentation is to highlight the impact of media involvement in relation to the MMIWG epidemic.Psycholog

    Objective: <br/> <br/> To determine the incidence of delirium in those patients presenting to a psychiatric clinic in Nigeria and to examine if any demographic or clinical variables were correlated with this diagnosis. <br/> <br/> Method <br/> <br/> A prospective survey design; 264 consecutive new referrals to a psychiatric clinic in Nigeria were assessed for the presence of delirium using a standardised diagnostic scale. Data was analysed for normality and appropriate statistical test employed to examine the relationships between the presence of delirium and demographic and clinical variables. <br/> <br/> Results <br/> <br/> Of individuals presenting to the mental health clinics, 18.2% had delirium. No demographic variable was significant regarding the presence or absence of delirium. With regard to clinical variables duration of current symptoms, referral source and the presence of comorbid physical illness were significantly associated with the presence of delirium. Most delirium was due to infections. Nearly all patients with delirium were prescribed psychotropic medication (95.2%), and most attributed their symptoms to a spiritual cause.Conclusion(s) Delirium presents more commonly to psychiatry services in the less developed world compared to the West. Development efforts should focus on recognition and management of delirium to improve outcomes and maximise resource
