Moral values and moral identity moderate the indirect relationship between sport supplement use and doping use via sport supplement beliefs

The Incremental Model of Doping Behaviour suggests doping grows out of the habitual use of performance-enhancing methods (e.g., sport supplements) and belief that they are necessary for performance. Importantly, in this model, doping is viewed as functional rather than moral choice. In two studies, we examined whether sport supplement use was indirectly related to doping use via sport supplement beliefs, and whether personal morality moderated this relationship. Competitive athletes (Study 1, N = 366; Study 2, N = 200) completed measures of supplement use, beliefs, and doping use. They also completed measures of moral values (Study 1) and moral identity (Study 2). In both studies, supplement use was indirectly related to doping use via beliefs. Moreover, this indirect relationship was moderated by moral values (Study 1) and moral identity (Study 2). That is, the relationship between supplement use and doping use via beliefs was negated when moral values and moral identity were high but not when they were low or moderate. Taken together, our findings suggest that sport supplement users, who believe they are necessary, are more likely to dope if they have low moral values and believe that being a moral person is unimportant to their self-image

Automating Carotid Intima-Media Thickness Video Interpretation with Convolutional Neural Networks

Cardiovascular disease (CVD) is the leading cause of mortality yet largely preventable, but the key to prevention is to identify at-risk individuals before adverse events. For predicting individual CVD risk, carotid intima-media thickness (CIMT), a noninvasive ultrasound method, has proven to be valuable, offering several advantages over CT coronary artery calcium score. However, each CIMT examination includes several ultrasound videos, and interpreting each of these CIMT videos involves three operations: (1) select three end-diastolic ultrasound frames (EUF) in the video, (2) localize a region of interest (ROI) in each selected frame, and (3) trace the lumen-intima interface and the media-adventitia interface in each ROI to measure CIMT. These operations are tedious, laborious, and time consuming, a serious limitation that hinders the widespread utilization of CIMT in clinical practice. To overcome this limitation, this paper presents a new system to automate CIMT video interpretation. Our extensive experiments demonstrate that the suggested system significantly outperforms the state-of-the-art methods. The superior performance is attributable to our unified framework based on convolutional neural networks (CNNs) coupled with our informative image representation and effective post-processing of the CNN outputs, which are uniquely designed for each of the above three operations.Comment: J.

The effect of 12 weeks of combined upper- and lower-body high-intensity interval training on muscular and cardiorespiratory fitness in older adults

Background: High-intensity interval training (HIT) can impact cardiorespiratory and muscular fitness simultaneously, yet protocols typically focus on lower-body exercise. For older adults however, performing activities of daily living requires upper- and lower-body fitness. Aims: To assess the effects of combined upper- and lower-body HIT on fitness in adults aged > 50 years. Methods: Thirty-six adults (50–81 years; 21 male) were assigned via minimisation to either HIT (n = 18) or a no-exercise control group (CON, n = 18) following baseline assessment of leg extensor muscle power, handgrip strength, cardiorespiratory fitness (predicted VO2max) and health-related quality of life (HRQoL). The HIT group completed two training sessions per week for 12-weeks, performing a combination of upper-, lower- and full-body exercises using a novel hydraulic resistance ergometer. Data were analysed via ANCOVA with probabilistic inferences made about the clinical relevance of observed effects. Results: All participants completed the intervention with mean (82 ± 6%HRmax) and peak (89 ± 6%HRmax) exercise heart rates confirming a high-intensity training stimulus. Compared with CON, HIT showed possibly small beneficial effects for dominant leg power (10.5%; 90% confidence interval 2.4–19.4%), non-dominant leg power (9.4%; 3.3–16.0%) and non-dominant handgrip strength (6.3%; 1.2–11.5%) while the intervention effect was likely trivial (5.9%; 0.5–11.5%) for dominant handgrip strength. There was a likely small beneficial effect for predicted VO2max (8.4%; 1.8–15.4%) and small-moderate improvements across several domains of HRQoL. Conclusion: Combined upper- and lower-body HIT has small clinically relevant beneficial effects on muscular and cardiorespiratory fitness in older adults

Workshopped plays in a South African correction centre : negotiating social relations through theatre.

Thesis (Ph.D.)-University of KwaZulu-Natal, Durban, 2009.From 1999 until 2008 I worked with offenders making plays at Westville Medium B Correction Centre, using collective techniques to address social issues and involve the audience in debates. This work was inspired by the Southern African Theatre for Development of the 1980s. During 2002 and 2003 the offenders created and performed the two plays which form the case studies for this research. Isikhathi Sewashi (The Time of the Watch), presents their experiences of growing up under apartheid, political faction fighting, and crime and asks the audience to generate solutions to crime. Lisekhon’ Ithemba (There is Still Hope) addresses the prejudice of the correctional staff and offenders towards those living with HIV/AIDS. Offenders were involved in the research process and conducted group interviews with 110 members of the audience. I conducted interviews with 21 performers and used classical Grounded Theory to analyse the interviews. The theory that emerged demonstrates how the offenders, performers and audience used theatre to negotiate social relations. The plays negotiated the stereotyping of offenders, managed conflict, and increased care for offenders who were ill. Offenders also used the plays to negotiate power relations involving the correctional system and the numbers gangs. Collective play-making techniques allowed western and African aesthetics to combine. The aesthetics of Epic Theatre and Theatre of the Oppressed combined with those of isiZulu popular performance. The theories of Freire (1996:64), Brecht (in Willet 1964: 57) and Boal (1979:xix–xxi) had the intention of promoting actions and change of a social and political nature. Both Soyinka (1976: 51) and Kamlongera (n.d. 18-26) argue that theatre that engages an African worldview has its roots in social functions involving man and his environment. The offenders’ identification with characters and situations, their feelings of regret and self-pity, drove their critical engagement with the plays. They then formulated solutions and took action to effect change. Some of their actions challenged the authority of the correctional system and the numbers gang. The binary formulation of Aristotelian and non-Aristotelian theatre in the work of Brecht (in Willet 1964: 281) and Boal (2000: xix –xxi) is contradicted in this case study. Elements from both forms co-exist here. The audience’s responses to the plays reflect what Freire (1996:33) refers to as domesticating oppression but also demonstrate praxis which emerges as forms of resistance, and self-creation. The offenders’ potential to effect change in the correction centre, however, remains limited. My findings address current debates in the field of Prison Theatre (Thompson 1998:11 and Balfour 2004: 1-18) about the potential for theatre to effect change beyond offending behaviour and to include systemic change within the correctional system. Collective play-making provides offenders with a voice in the correction centre. The power of collective play-making is that cultural production remains in the hands of offenders and becomes a means through which they can expresses their concerns and sense of reality. Further research around collective play-making in other contexts and involving communities with different cultural resources is needed to validate the emergent theory presented here or to arrive at further reformulations

Patterns in Curriculum Choices: Pre-Calculus Curricula in the Archdiocese of Washington

This study aims to learn more about the choices made by mathematics teachers in the Archdiocese of Washington, given their unique independence from state or district curricular control. To study these choices, pre-calculus teachers completed a survey and submitted their course’s summative assessments. These responses were then compared to themselves, to each other, and to the Common Core to study the choices teachers made, both in the scope of their curricula and in the expectations they had for student performance. This study concludes that teachers choose pre-calculus curricula within two major archetypes, either advancing students’ algebraic skill or exploring new topics. Further, the study found that teachers’ assessments are well aligned to their stated curriculum, but that contrary to recent education trends, teachers have largely chosen to ignore statistics. Consequences of these choices are discussed, as well as implications for policy and future research
