SAFEGUARDING AMATEUR ATHLETES AN EXAMINATION OF PLAYER WELFARE AMONG SENIOR INTER-COUNTY GAELIC PLAYERS. RESEARCH SERIES NUMBER 99 December 2019

Following the publication of research into the commitments required of male Gaelic players to play senior inter-county, and knock-on effects of inter-county commitment (Kelly et al., 2018), the Gaelic Athletic Association (GAA) and Gaelic Players Association (GPA) established a working group to make an in-depth analysis of the report’s findings. One of the decisions taken by the working group was that further research was required to examine a range of issues that emerged from the original study. These included in particular: (i) the education and (ii) the professional career experiences of senior inter-county players, (iii) their engagement in risky behaviours (e.g. alcohol consumption), (iv) supplement usage, (v) players’ views on both provided and required supports, and (vi) what they would change about their experience of playing inter-county and the inter-county set-up

Sloth: America\u27s Ironic Structural Vice

Individualism is a popular cultural trope in the United States, often touted for its promotion of industriousness and rejection of laziness. This essay argues that, ironically, America\u27s brand of individualism actually promotes a more fundamental form of the very vice it purports to oppose. To make this case, the essay defines the unique form of individualism in the United States and then retrieves the classical definition of sloth as a vice against charity (not diligence), contrasting Aquinas and Barth with Weber to demonstrate that this peculiarly American individualist impulse undermines civic charity by reaping the benefits of civic relationships while denying any concomitant responsibilities. Identifying this narrative of individualism as a structural vice, the essay proposes structural remedies for reinvigorating civic charity, solidarity, and the common good in the United States

Jellyfish: The origin and distribution of extreme ram-pressure stripping events in massive galaxy clusters

We investigate the observational signatures and physical origin of ram-pressure stripping (RPS) in 63 massive galaxy clusters at z = 0.3–0.7, based on images obtained with the Hubble Space Telescope. Using a training set of a dozen ‘jellyfish’ galaxies identified earlier in the same imaging data, we define morphological criteria to select 211 additional, less obvious cases of RPS. Spectroscopic follow-up observations of 124 candidates so far confirmed 53 as cluster members. For the brightest and most favourably aligned systems, we visually derive estimates of the projected direction of motion based on the orientation of apparent compression shocks and debris trails. Our findings suggest that the onset of these events occurs primarily at large distances from the cluster core (>400 kpc), and that the trajectories of the affected galaxies feature high-impact parameters. Simple models show that such trajectories are highly improbable for galaxy infall along filaments but common for infall at high velocities, even after observational biases are accounted for, provided the duration of the resulting RPS events is ≲500 Myr. We thus tentatively conclude that extreme RPS events are preferentially triggered by cluster mergers, an interpretation that is supported by the disturbed dynamical state of many of the host clusters. This hypothesis implies that extreme RPS might occur also near the cores of merging poor clusters or even merging groups of galaxies. Finally, we present nine additional ‘jellyfish” galaxies at z > 0.3 discovered by us, thereby doubling the number of such systems known at intermediate redshift

Engineering ambient visual sensors

Visual sensors are an indispensable prerequisite for those AmI environments that require a surveillance component. One practical issue concerns maximizing the operational longevity of such sensors as the operational lifetime of an AmI environment itself is dependent on that of its constituent components. In this paper, the intelligent agent paradigm is considered as a basis for managing a camera collective such that the conflicting demands of power usage optimization and system performance are reconciled

Segregation in Oslo

I den første delen av denne studien gjennomfører jeg en statistisk analyse av segregering i Oslo på grunnlag av Massey og Dentons segregeringsindekser fra 1988. Mens tidligere studier har benyttet seg av ett av fem av Massey og Dentons indekser for å studere segregering i Norge, utfører jeg analysen ved å bruke den fullstendige målingen og konkluderer med at det finnes en moderat grad av segregering blant noen innvandrergrupper i Oslo. Videre fremhever jeg de konseptuelle, operasjonelle og metodologiske manglene ved tidligere statsstøttet forskning i denne retningen. I den andre delen av denne studien gjennomgår jeg sosiologiske rammer om "race" som en sosialt konstruert analytisk kategori og gjentar oppfordringer til å avhøre norsk colorblindness i sammenheng med den institusjonelle fornektelsen av historisk og moderne norsk kolonialisme og imperialisme, samt nåværende strukturell rasisme i det norske samfunnet. Til slutt tilbyr jeg argumenter og forslag for utviklingen av studiet av racialization i Norge fra et statistisk informert perspektiv.In the first part of this study, a statistical analysis of segregation in Oslo is carried out on the basis of Massey and Denton's 1988 segregation indices. While earlier studies have made use of one of five of Massey and Denton's indices to study segregation in Norway, I perform the analysis using the complete measure and conclude that there exists a moderate degree of segregation among some immigrant groups in Oslo. Moreover, I highlight the conceptual, operational, and methodological shortcomings of prior state-sponsored research in this direction. In the second part of this study, I review sociological frameworks on "race" as a socially constructed analytic category and reiterate calls to interrogate Norwegian colorblindness in the context of the institutional denial of historical and contemporary Norwegian colonialism and imperialism, as well as current structural racism in Norwegian society. Finally, I offer arguments and suggestions for the development of the study of racialization in Norway from a statistically informed perspective

Coupling Freshly Isolated CD44(+) Infrapatellar Fat Pad-Derived Stromal Cells with a TGF-β3 Eluting Cartilage ECM-Derived Scaffold as a Single-Stage Strategy for Promoting Chondrogenesis.

An alternative strategy to the use of in vitro expanded cells in regenerative medicine is the use of freshly isolated stromal cells, where a bioactive scaffold is used to provide an environment conducive to proliferation and tissue-specific differentiation in vivo. The objective of this study is to develop a cartilage extracellular matrix (ECM)-derived scaffold that could facilitate the rapid proliferation and chondrogenic differentiation of freshly isolated stromal cells. By freeze-drying cryomilled cartilage ECM of differing concentrations, it is possible to produce scaffolds with a range of pore sizes. The migration, proliferation, and chondrogenic differentiation of infrapatellar fat pad-derived stem cells (FPSCs) depend on the concentration/porosity of these scaffolds, with greater sulphated glycosaminoglycan (sGAG) accumulation observed in scaffolds with larger-sized pores. It is then sought to determine if freshly isolated fat pad-derived stromal cells, seeded onto a transforming growth factor (TGF)-β3 eluting ECM-derived scaffold, could promote chondrogenesis in vivo. While a more cartilage-like tissue could be generated using culture expanded FPSCs compared to nonenriched freshly isolated cells, fresh CD44(+) stromal cells are capable of producing a tissue in vivo that stained strongly for sGAGs and type II collagen. These findings open up new possibilities for in-theatre cell-based therapies for joint regeneration
