Knowledge,nutrition and coaching pedagogy: a perspective from female Brazilian Olympic gymnasts

It is acknowledged that knowledge and knowledge bases are an important part of coach and athlete learning and that the coach – athlete relationship is crucial to knowledge created, shared and used. This said knowledge about nutrition as constructed by elite gymnasts would seem particularly important in a culture long associated with weight control practices and disordered eating. This paper provides an insight into the ways that 10 Brazilian Olympic gymnasts construct ideas pertaining to nutritional knowledge across generational periods (between 1980 and 2004) where significant organisational change in Women’s Artistic Gymnastics in Brazil occurred and included the introduction of dieticians. Drawing upon different knowledge types and paying attention to the coaching context, the life histories of 10 Olympic gymnasts were used to open a window on knowledge construction pertaining to nutrition by three generations of gymnasts. The findings draw attention to two main illustrative themes. Firstly, coaches’ personal knowledge, whilst perceived as incomplete by gymnasts, reinforced a narrative of weight loss for gymnasts regardless of generation. Secondly, the younger generations of gymnasts perceived that the introduction of dieticians into structured provision enabled them to use better structured knowledge, and with it a sense of increased autonomy and corporeal learning via the construction of tacit embodied knowledge leading to healthier practices. Reflections are given to the role of the coach, dieticians and pedagogical actions, and the continued reshaping of knowledge in elite gymnastics.     

Applying and Interpreting Mixture Distribution Latent State-Trait Models

Latent state-trait (LST) models are commonly applied to determine the extent to which observed variables reflect trait-like versus state-like constructs. Mixture distribution LST (M-LST) models relax the assumption of population homogeneity made in traditional LST models, allowing researchers to identify subpopulations (latent classes) with differing trait- and state-like attributes. Applications of M-LST models are scarce, presumably because of the analysis complexity. We present a step-by-step tutorial for evaluating M-LST models based on an application to mother, father, and teacher reports of children’s inattention (n = 811). In the application, we found three latent classes for mother and father reports and four classes for teacher reports. All reporter solutions contained classes with very low, low, and moderate levels of inattention. The teacher solution also contained a class with high inattention. Comparable mother and father (but not teacher) classes exhibited similar levels of trait and state variance.     

From 1883 to 2019; Variables Influencing Body Procurement at McGill University

McGill University has continued to maintain whole body dissection as an integral component of its medical school curriculum. To better explore the factors influencing body procurement at McGill University, records of body receipts were collected from their paper and electronic records and analyzed from 1883 to 2019. The data collected allowed for discussion on the number of bodies received at McGill University each year, the age at death of the bodies, their sex, as well as religious affiliation and language spoken at home. As bodies of the deceased have a long held and unique status in law, this information was considered in light of historical and legislative data and, in the case of religion and language, it was compared to census data for Montréal, Québec, Canada. Overall numbers of bodies procured by McGill University have varied throughout the years, with no discernable target number over time. The current body donor profile at McGill University is likely to be a male in his 70's and likely to speak French at home. However, the strong connection of the University with the Anglophone community of Montréal is reflected by the significantly higher proportion of English-speaking donors when compared to the general population of the city. In regard to legislation, it appears that the most recent legislations did not affect the rate of procurement. However, when legislations were embraced by religious institutions in 1883, there was a 261% increase in bodies sent for dissection, over the following two decades.     

College Counselors' Perceptions of Working With First‐Year Students With Chronic Illnesses

Despite increased interest in college students' success, there has been little research regarding students entering college with chronic illnesses such as asthma, diabetes, and cancer. This qualitative study examined 15 college counselors' perceptions of working with first‐year students with chronic illnesses. Four themes emerged from the findings: counseling preparation, interactions, counseling interventions, and needs of students. The authors discuss implications for college counseling training and practice and directions for future research.     

A Matter of Regionalism: Remembering Brandon Teena and Willa Cather at the Nebraska History Museum

In 2010–2011, the Nebraska History Museum featured two temporary exhibits: “We the People: the Nebraskan Viewpoint” and “Willa Cather: A Matter of Appearances.” We argue the public memories of Brandon Teena and Willa Cather contained in the exhibits are distanced from regional politics when articulated alongside the nostalgic regionalist rhetoric of the Nebraska History Museum. Specifically, both exhibits not only discipline the memory of trans* performance within problematic material and symbolic contexts, but also place these memories within a rhetoric of regional optimism that has critical consequences for restricting counter-public formation. In performing this reading, the essay argues that critical regionalism has the potential to offer a nuanced perspective on the geopolitical dimensions of memory places by exploring understandings of the relationship between “local” and “national” commemoration at these sites.     

Replication of the Mere Presence Hypothesis: The Effects of Cell Phones on Face-to-Face Conversations

Research on the mere presence hypothesis shows mixed findings for the effects of cell phone presence on various conversation outcomes. The current study performed a partial replication of Przybylski and Weinstein’s (2013) study, which showed that strangers were likely to report lower levels of relational quality and empathy (among other variables) when a cell phone was placed in their view, particularly when their conversations were rated as meaningful. The results of the current study failed to replicate Przybylski and Weinstein’s (2013) findings, because cell phone presence did not significantly influence relational quality or empathy, nor was meaningfulness a moderator of cell phone presence on conversation outcomes. Changing norms in cell phone usage and competing explanations for cell phone effects are explored as possible explanations for the failure to replicate.

Effect of precooling and acclimation on repeat-sprint performance in heat

Abstract

This study determined whether precooling would have an additive effect on repeat-sprint cycling performance in heat following partial acclimation. Ten males completed three trials; Pre Acclimation (Pre Acc) and two Post Acclimation trials, one with precooling (ice jacket and slushy; Post Acc +PC) and another without (Post Acc). Trials consisted of a 30-min baseline period followed by a 70-min repeat-sprint protocol in ～35°C and 60% relative humidity. Separating pre and post trials were five heat acclimation sessions. Although no significant differences were found for performance variables, inferential statistical analysis resulted in moderate effect sizes, which suggested more work (J · kg^?1) was performed in Post Acc compared with Pre Acc. Further, ‘possible’ and ‘very likely’ benefits were found for every performance variable for Post Acc compared with Pre Acc, while ‘possible’ benefits were found for Post Acc, compared with Post Acc +PC, for peak power output (W and W · kg^?1). Moderate to strong effect sizes suggested lower core temperatures in both post acclimation trials compared with Pre Acc. Sweat loss was significantly higher (P < 0.05; 23.1%) in Post Acc +PC compared to other trials. In conclusion, no additional performance enhancement was seen when partially acclimated individuals precooled prior to repeat-sprint performance in heat.     

Effectiveness of hand cooling and a cooling jacket on post-exercise cooling rates in hyperthermic athletes

This study compared the effects of a hand cooling glove (～16°C water temperature; subatmospheric pressure of ?40 mmHg) and a cooling jacket (CJ) on post-exercise cooling rates (gastrointestinal core temperature, Tc; skin temperature, Tsk) and cognitive performance (the Stroop Colour–Word test). Twelve male athletes performed four trials (within subjects, counterbalanced design) involving cycling at a workload equivalent to 75% ?O₂max in heat (35.7?±?0.2°C, 49.2?±?2.6% RH) until a Tc of 39°C or exhaustion occurred. A 30-min cooling period (in 22.3?±?0.3°C, 42.1?±?3.6% RH) followed, where participants adopted either one-hand cooling (1H), two-hand cooling (2H), wore a CJ or no cooling (NC). No significant differences were seen in Tc and Tsk cooling rates between trials; however, moderate effect sizes (d?=?0.50–0.76) suggested Tc cooling rates to be faster for 1H, 2H and CJ compared to NC after 5 min; 1H and CJ compared to NC after 10 min and for CJ to be faster than 2H at 25–30 min. Reaction times on the cognitive test were similar between all trials after the 30 min cooling/no-cooling period (p?>?.05). In conclusion, Tc cooling rates were faster with 1H and CJ during the first 10 min compared to NC, with minimal benefit associated with 2H cooling. Reaction time responses were not impacted by the use of the glove(s) or CJ.     

Student or scholar? Transforming identities through a research writing group

This article explores the role a writing group played in influencing the scholarly identities of a group of doctoral students by fostering their writing expertise. While the interest in writing groups usually centres on their potential to support doctoral students to publish, few studies have been conducted and written by the students themselves. Using a situated learning perspective on identity, we explore the connection that emerged between our perceptions of ourselves as developing expertise as scholarly writers and the function of the writing group as a dynamic space for transforming our identities. Findings show that our writing group served as a flexible and interactive Community of Practice (CoP) that shaped critical and durable shifts in identity amongst members.
