The Influence Of Geographic Ranges, Climatic Niches And Temperature Fluctuations On Population Variability, Cleber Ten Canten, Lauren Holian, Tad Dallas

Faculty Publications

The existence of patterns in population dynamics across species geographic ranges and climatic niches is a pervasive idea in ecology. Population variability (i.e. temporal variability in population density) should hypothetically increase near range edges or niche limits because of less suitable environments in these areas, but the occurrence of such patterns remains largely unexplored. Further, fluctuations in temperature could pose demographic constraints on populations and also influence their variability. We used Breeding Bird Survey data to show that the population variability of 97 resident North American birds consistently increases towards their niche limits and in areas with more variable temperatures, …

Ncaa Student-Athletes' Sports Gambling Behaviors Examined Using Psychological Reactance Theory, Braden E. Norris, Paul M. Pedersen

Journal of Issues in Intercollegiate Athletics

Since the repeal of the Pro and Amateur Sports Protection Act (PASPA) in 2018, sports gambling has been a rapidly growing segment of the sport world. The United States federal government has left it up to individual states to legalize and govern the activity of sports gambling, however, the National Collegiate Athletic Association (NCAA) still prohibits (Bylaw 10.3) the activity regardless of legality. With it known that student-athletes violate Bylaw 10.3 (e.g., Paskus & Derevensky, 2025; Richard et al., 2019), this study examined sports gambling behaviors through under the scope of Psychological Reactance Theory (PRT) to investigate if student-athletes’ sports …

Recruitment Of International College Athletes (Icas) To The United States: A Bourdieuian Examination Of Pathways To Success, Simran Kaur Sethi, Kirsten Hextrum, Kaitlin Pericak

Journal of Issues in Intercollegiate Athletics

Successful recruitment pathways of international college athletes (ICAs) remain understudied. We use Bourdieu’s capital exchange theory to examine how ICAs acquire and deploy forms of capital to navigate college athletic recruitment. Bourdieu posits that individuals accumulate different forms of capital, including economic, social, and cultural capital, which they can use to gain access to resources and opportunities. In the context of athletic recruitment, ICAs may need to acquire different forms of capital than their domestic counterparts. Thus, we use a qualitative research design to explore how ICAs navigate the recruitment process. Findings from our study provide valuable insights into the …

We investigate the capabilities of the mid-infrared instrument (MIRI) of JWST to advance our knowledge of active galactic nucleus (AGN) dust using the spectral fitting technique on an AGN collection of 21 nearby (z < 0.05) AGN (7 type-1 and 14 type-2) observations obtained with the medium resolution spectroscopy (MRS) mode. This collection includes publicly available AGN and data from the collaboration of Galactic Activity, Torus, and Outflow Survey (GATOS). We developed a tool named MRSPSFisol that decomposes MRS cubes into point-like and extended contributions. We found statistically good fits for 12 targets with current AGN dust models. The model that provides good fits (χ²/dof< 2) for these 12 targets assumes a combination of clumpy and smooth distribution of dust in a flare-disc geometry where the dust grain size is a free parameter. Still, two and one AGN statistically prefer the disc + wind and the classical clumpy torus model, respectively. However, the currently available models fail to reproduce 40 per cent of the targets, likely due to the extreme silicate features not well reproduced by the models and signatures of water-ice and aliphatic hydrocarbon absorption features in most targets. New models exploring, for instance, new chemistry, are needed to explain the complexity of AGN dust continuum emission observed by JWST.
