Humour, Masculinities and Youth Sport Coaching: ‘Good Morning, Ladies!’.

In this paper, I explore male youth sport coaches’ use of humour in relation to the reconstruction of masculinities, contributing to an emergent body of literature on the role of humour in coaching. Three creative non-fiction stories developed from my own coaching experiences in a competitive youth football (soccer) academy are used to examine: (1) coaches’ reconstruction of hegemonic/esteemed masculinities; (2) coaches’ use of humour to encourage re-alignment with hegemonic masculinities, and; (3) coaches’ use of (counter-)humour to disrupt hegemonic representations of masculinities. The stories offer sport coaches and educators with a resource to reflect on masculinities, gender relations, and the everyday use of humour within their own contexts

Experiencing the felt difficulty of sport coaching violence. Evidence and reflections from the arts-informed practitioner education event, ways of seeing sport coaching violence

Amidst a backdrop of global patterns of abuse identified in various high-performance sport settings, this study is anchored on a commitment to bring to life the voices of abused athletes and to educate practitioners on the topic of abuse in sport. The case combined previously collected data (Kavanagh, 2014; Kavanagh et al. 2017) and, guided by art-informed pedagogy, led to the construction of an immersive audio-visual experience. Sport practitioners (including coaches and sport psychologists) were invited to attend the exhibition to be confronted by and with(in) athletes’ verbatim stories of abuse. Sixty-four participants attended the exhibition, of those, thirty-one attendees completed a post-event questionnaire and seven attendees participated in semi-structured interviews, providing an in-depth insight into their experiences of the event. In this paper we share our experience of creating the exhibition and the themes generated from the qualitative data: (1) practitioners experienced the physical space of the event as ‘moving’ and ‘difficult’ both physically and emotionally, and; (2) this ‘felt difficulty’ reverberated beyond the event, compelling participants to reflexively make sense of their emotions and reflect upon their own practice. We make recommendations for the potential of arts-informed pedagogy within future practitioner education contexts to afford engagement with critical contemporary topics underpinning applied practice

pavarotti encodes a kinesin-like protein required to organize the central spindle and contractile ring for cytokinesis

Mutations in the Drosophila gene pavarotti result in the formation of abnormally large cells in the embryonic nervous system. In mitotic cycle 16, cells of pav mutant embryos undergo normal anaphase but then develop an abnormal telophase spindle and fail to undertake cytokinesis. We show that the septin Peanut, actin, and the actin-associated protein Anillin, do not become correctly localized in pav mutants. pav encodes a kinesin-like protein, PAV–KLP, related to the mammalian MKLP-1. In cellularized embryos, the protein is localized to centrosomes early in mitosis, and to the midbody region of the spindle in late anaphase and telophase. We show that Polo kinase associates with PAV–KLP with which it shows an overlapping pattern of subcellular localization during the mitotic cycle and this distribution is disrupted in pavmutants. We suggest that PAV–KLP is required both to establish the structure of the telophase spindle to provide a framework for the assembly of the contractile ring, and to mobilize mitotic regulator proteins

Closed Strings Tachyons and Non-Commutative Instabilities

We observe a relation between closed strings tachyons and one-loop instabilities in non-supersymmetric non-commutative gauge theories. In particular we analyze the spectra of type IIB string theory on C^3/Z_N orbifold singularities and the non-commutative field theory that lives on D3 branes located at the singularity. We find a surprising correspondence between the existence or not of one-loop low-momentum instabilities in the non-commutative field theory and the existence or not of tachyons in the closed string twisted sectors. Moreover, the relevant piece of the non-commutative field theory effective action is suggestive of an exchange of closed string modes. This suggests that non-commutative field theories retain some information about the dynamics of the underlying string configuration. Finally, we also comment on a possible relation between closed string tachyon condensation and field theory tachyon condensation.Comment: 27 pages, Latex. v2: Comment about anomalies and refs. added.

Managing abuse in sport: An introduction to the special issue

This special issue was designed to advance a research agenda focussed on the management of abuse in sport. Despite progress in the field, greater attention to the structures, policies, processes, practices, and sites in which abuse occurs is required. As such, there is a need for evidence-based solutions to improve the management of abuse and integrity in sport. The authors identified 5 overarching themes across the 12 papers included within the special issue: the harms and legacies of abuse; abuse in mediated environments; abuse of referees; frameworks that sustain abuse; and safeguarding. The articles included in this issue highlight the complexity of abuse in sporting spaces, the impact it can have on victims and the challenges faced in appropriately managing sporting spaces toward the reduction of harm. This special issue is driven by the authors’ desire to promote integrity and enrich the sporting experience for all, with the hope of driving further research into the management of abuse and integrity in sport

Thrombospondin-1-N-Terminal Domain Induces a Phagocytic State and Thrombospondin-1-C-Terminal Domain Induces a Tolerizing Phenotype in Dendritic Cells

In our previous study, we have found that thrombospondin-1 (TSP-1) is synthesized de novo upon monocyte and neutrophil apoptosis, leading to a phagocytic and tolerizing phenotype of dendritic cells (DC), even prior to DC-apoptotic cell interaction. Interestingly, we were able to show that heparin binding domain (HBD), the N-terminal portion of TSP-1, was cleaved and secreted simultaneously in a caspase- and serine protease- dependent manner. In the current study we were interested to examine the role of HBD in the clearance of apoptotic cells, and whether the phagocytic and tolerizing state of DCs is mediated by the HBD itself, or whether the entire TSP-1 is needed. Therefore, we have cloned the human HBD, and compared its interactions with DC to those with TSP-1. Here we show that rHBD by itself is not directly responsible for immune paralysis and tolerizing phenotype of DCs, at least in the monomeric form, but has a significant role in rendering DCs phagocytic. Binding of TSP-1-C-terminal domain on the other hand induces a tolerizing phenotype in dendritic cells

Unscrambling the lensed galaxies in JWST images behind SMACS0723

The first deep field images from the James Webb Space Telescope (JWST) of the galaxy cluster SMACS~J0723.3-7327 reveal a wealth of new lensed images at uncharted infrared wavelengths, with unprecedented depth and resolution. Here we securely identify 14 new sets of multiply imaged galaxies totalling 42 images, adding to the five sets of bright and multiply-imaged galaxies already known from Hubble Space Telescope data. We find examples of arcs crossing critical curves, allowing detailed community follow-up, such as JWST spectroscopy for precise redshift determinations, and measurements of the chemical abundances and of the detailed internal gas dynamics of very distant, young galaxies. One such arc contains compact knots of magnification $\mu\sim$750, and features a microlensed transient. We also detect an Einstein cross candidate only visible thanks to JWST's superb resolution. Our parametric lens model is available at https://www.dropbox.com/sh/gwup2lvks0jsqe5/AAC2RRSKce0aX-lIFCc9vhBXa?dl=0 , and will be regularly updated using additional spectroscopic redshifts. The model reproduces the multiple images to better than an rms of $0.5^{\prime \prime}$, and allows for accurate magnification estimates of high-redshift galaxies. The intracluster light extends beyond the cluster members, exhibiting large-scale features that suggest a significant past dynamical disturbance. This work represents a first taste of the enhanced power JWST will have for lensing-related science.Comment: Submitted to ApJ. 13 pages, 6 figure

“I Kiss Them Because I Love Them”: The Emergence of Heterosexual Men Kissing in British Institutes of Education.

In this article, we combined data from 145 interviews and three ethnographic investigations of heterosexual male students in the U.K. from multiple educational settings. Our results indicate that 89% have, at some point, kissed another male on the lips which they reported as being non-sexual: a means of expressing platonic affection among heterosexual friends. Moreover, 37% also reported engaging in sustained same-sex kissing, something they construed as non-sexual and non-homosexual. Although the students in our study understood that this type of kissing remains somewhat culturally symbolized as a taboo sexual behavior, they nonetheless reconstructed it, making it compatible with heteromasculinity by recoding it as homosocial. We hypothesize that both these types of kissing behaviors are increasingly permissible due to rapidly decreasing levels of cultural homophobia. Furthermore, we argue that there has been a loosening of the restricted physical and emotional boundaries of traditional heteromasculinity in these educational settings, something which may also gradually assist in the erosion of prevailing heterosexual hegemony

Exploring the relationship between homosexuality and sport among the teammates of a small, Midwestern Catholic college soccer team.

Despite decreasing homophobia, openly gay male athletes are still rare in organized, competitive teamsports. In this action research, we explore two aspects of homosexuality and sport: (1) the effect of a gay male soccer player coming out to his teammates; and (2) the effect of having an openly gay researcher in the field. This is, therefore, the first-ever first-hand account of an athlete's coming-out process with researchers in the field. Even though this is action research and, therefore, not generalizable, we highlight that this research contributes to the body of literature on sexuality and sport because we document the interactions of straight athletes with a gay player and a gay researcher among the heterosexual players at a small, Catholic college in the American Midwest. We use interviews to show that players were accepting of homosexuality before the beginning of this research and show that discussions with these two gay men further promoted players' perspectives on homosexuality. This led to an increase in the team's social cohesion and a decrease in heteronormativity
