Predictors of Pregnancy Disclosure in National Collegiate Athletic Association Division III Athletes.

CONTEXT: Pregnant athletes cannot receive proper care if they choose to conceal their pregnancy. Unfortunately, many factors may lead an athlete to conceal. Whereas the extant qualitative literature suggests scholarship and sponsorship are prominent factors in the decision to disclose, this research is limited to elite athletes. OBJECTIVE: To quantitatively examine predictors of pregnancy disclosure beyond scholarship and sponsorship in National Collegiate Athletic Association Division III college athletes. DESIGN: Cross-sectional study. SETTING: Midwestern United States. PARTICIPANTS OR OTHER PARTICIPANTS: Athletes on Division III women's sports teams (N = 127). MAIN OUTCOME MEASURE(S): Confidence in the athletic trainer (AT), perceived training and performance changes, athletic identity, and athletic identity during pregnancy. Two separate multiple regression analyses were conducted with the 4 predictors and 2 outcomes: likelihood to disclose and time to disclosure. RESULTS: Confidence in the AT and athletic identity during pregnancy were significant predictors in both models, whereas the variable of perceived training and performance changes was only significant in the likelihood to disclose model. Athletic identity was not a significant predictor in either model. Results suggest Division III athletes believe they would be more likely to disclose their pregnancy and may disclose sooner if they feel that their AT can properly manage their physical, emotional, and social wellness during the pregnancy. Additionally, disclosure is promoted if they believe they will still be viewed as athletes by themselves and the people around them. CONCLUSIONS: These findings emphasize the importance of the role of the AT, with implications that formal education of ATs should include the holistic support of the pregnant athlete.

Morality- and Norm-Based Subgroups of Disability-Sport Athletes Differ on Their Anticipated Guilt and Intentions Toward Doping.

The purpose of this study was to examine whether subgroups of disability-sport athletes exist on morality- and norm-based doping cognitions and whether these groups differ in anticipated guilt or doping intentions. A survey was completed by 186 athletes (Mage = 37.5 years, 78.0% male, 45.1% wheelchair basketball) assessing norms, doping moral disengagement, anticipated guilt, and intentions to dope. Cluster analysis revealed four distinct subgroups of athletes, including one potentially high-risk subgroup characterized by relatively high scores on doping moral disengagement, subjective norms, and descriptive norms. One-way analysis of variance revealed significantly lower anticipated guilt in two athlete subgroups characterized by relatively higher doping moral disengagement than the other two subgroups. Moreover, the potentially high-risk group had a greater proportion of athletes showing some presence of intention to dope. This study suggests there is a small subgroup of disability-sport athletes at elevated risk of doping who might benefit from targeted antidoping interventions.

Athlete doping confrontation efficacy and confrontation likelihood.

Evidence supports the role of coach doping confrontation efficacy (DCE; Sullivan et al., 2015) as a deterrent against athletes' doping cognitions (Boardley et al., 2019; Sullivan & Razavi, 2017), but the role of the athlete has largely been ignored. Current anti-doping campaigns encourage athletes to report doping misconduct (i.e., whistleblowing), but some athletes would prefer to confront the athlete directly (Erickson et al., 2017). Thus, it is important to consider what may contribute to athletes' likelihood to confront a doping teammate or opponent. The purpose of this study was to determine whether DCE could predict an athlete's likelihood to confront a doping teammate or opponent. Additionally, doping moral disengagement (MD) was included as a possible moderator of this relationship. Surveys were completed by 155 college athletes (nmale = 145) to measure their perceived DCE, doping MD, likelihood to confront a teammate, and likelihood to confront an opponent. Separate linear regression analyses were run for the two targets of confrontation. In the teammate model, both DCE and doping MD were significant predictors of confrontation likelihood. DCE was the only significant predictor in the opponent model. Neither model presented with a significant interaction, suggesting no moderation effect. Results suggest perceived DCE is associated with a greater likelihood to confront a doping athlete, regardless of whether they are a teammate or opponent; however, moral disengagement plays a greater role if the athlete is a teammate. These findings imply that confrontation may be the first line of defense against doping before whistleblowing action is taken. Research should continue to explore antecedents and consequences of athlete doping confrontation, providing greater insight into the whistleblowing process.

Perceptions of coach doping confrontation efficacy and athlete susceptibility to intentional and inadvertent doping.

OBJECTIVES: We tested a conceptually grounded model linking athlete perceptions of strength and conditioning and technical coach doping confrontation efficacy (DCE) with athletes' doping self-regulatory efficacy (SRE), doping moral disengagement (MD), and susceptibility to intentional and inadvertent doping. DESIGN: Cross-sectional, correlational. METHODS: Participants were high-level athletes (nmale  = 532; nfemale  = 290) recruited in Australia (n = 261), the UK (n = 300), and the USA (n = 261). All participants completed questionnaires assessing the variables alongside a variant of the randomized response technique to estimate the prevalence of doping. RESULTS: The estimated prevalence of intentional doping in the sample was 13.9%. Structural equation modeling established: (a) perceptions of technical and strength and conditioning coaches' DCE positively predicted doping SRE; (b) doping SRE negatively predicted doping MD; (c) doping MD positively predicted susceptibility to intentional and inadvertent doping; and (d) the predictive effects of coach perceptions on susceptibility to doping were mediated by doping SRE and doping MD. Multisample analyses demonstrated these predictive effects were invariant between males and females and across the three countries represented. CONCLUSIONS: The findings show the conceptually grounded model to offer extended understanding of how multiple individuals within the athlete support personnel network may influence athlete doping.

Rational Modification of a Metallic Substrate for CVD Growth of Carbon Nanotubes.

Growth of high quality, dense carbon nanotube (CNT) arrays via catalytic chemical vapor deposition (CCVD) has been largely limited to catalysts supported on amorphous alumina or silica. To overcome the challenge of conducting CNT growth from catalysts supported on conductive substrates, we explored a two-step surface modification that involves ion beam bombardment to create surface porosity and deposition of a thin AlxOy barrier layer to make the surface basic. To test the efficacy of our approach on a non-oxide support, we focus on modification of 316 stainless steel (SS), a well-known inactive substrate for CNT growth. Our study reveals that ion beam bombardment of SS has the ability to reduce film thickness of the AlxOy barrier layer required to grow CNTs from Fe catalysts to [Formula: see text] 5 nm, which is within the threshold for the substrate to remain conductive. Additionally, catalysts supported on ion beam-damaged SS with the same AlxOy thickness show improved particle formation, catalyst stability, and CNT growth efficiency, as well as producing CNTs with higher quality and density. Under optimal reaction conditions, this modification approach can lead to CNT growth on other nontraditional substrates and potentially benefit applications that require CNTs be grown on a conductive substrate.
