Assessing Lexical Proficiency In Russian As A Second Language Using Indices Of Lexical Sophistication, Diversity, And Fluency, Olesya Kisselev, Mihail Kopotev, Anton Vakhraney

Faculty Publications

Lexical proficiency in a second language (L2) has long been effectively assessed through the measurement of various lexical indices, or textual characteristics that act as observable indicators of such conceptual categories as lexical richness, diversity, sophistication, and fluency. While many studies have established links between these lexical characteristics and levels of overall language proficiency, languages other than L2 English rarely feature in such research. The current study addresses this gap by investigating a less commonly studied language, Russian, while paying specific attention to the operationalization of proficiency through an American Council for the Teaching of Foreign Languages Proficiency Guidelines-based procedure. …

Six Paths Of Global China: A Genealogy Of A Contested Geographical Imaginary, Jessica Dicarlo, Meredith J. Deboom

Faculty Publications

‘Global China’ has emerged as a shorthand for China's relationship to the global, but its axiomatic uses disguise considerable complexity. This article troubles self-evident uses and tidy categorizations of Global China by approaching it as an emergent, pluralistic geographical imaginary warranting critical analysis. Employing a genealogical approach that privileges indeterminacy and inconsistency over linearity and singularity, we draw on wide-ranging sources to reveal the contested, contextual, and contradictory uses of Global China in the contemporary moment. Our analysis identifies six ‘paths’ of Global China: Other, Integration, Bridge, Status, Threat, and Alternative. Each path facilitates distinct yet interlinked claims about …

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, …

College Student-Athlete Identity Unveiled: The Interplay Of Racial And Ethnic Subdimensions, Trevor Bopp, Rhema Fuller, Michael Stellefson

Journal of Issues in Intercollegiate Athletics

The racialized and institutionalized structure of the NCAA, college sports, and the PWIs that host most athletic programs positions racial and ethnic identity as a potential barrier to the social and academic engagement, mental health, and identity development of student-athletes. However, few studies examine the relationship, role, and influence of racial, student, and athlete identities outside of domain-specific outcomes. We collected data from 343 student-athletes to explore the relationships between student-athletes' academic and athletic identities, race centrality, and private and public regard, while also examining how race and ethnicity influence these identity dynamics.

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 …

Journal of Issues in Intercollegiate Athletics

While evidence supports the gradual return to participation in collegiate athletics following a concussion, limited evidence exists of the return to learn (RTL) procedures for a successful return to the higher education classroom. The objective of this study was to determine what academic supports and hindrances are present for NCAA student-athletes during the RTL process following a concussion from academic professionals’ perspectives. In this qualitative study with purposive recruitment strategies, academic support professionals (5=female, 4=male, age=44.2±13.9 years, experience=11.6±10.4 years) and faculty athletic representatives (5=female, 5=male, age=48.6±7.8 years, experience=3.9±5.6 years) volunteered to complete virtual interviews.

The Next Four Years: Geographical Reflections On The Second Trump Administration, Caroline R. Nagel, Peter Hopkins

Faculty Publications

In this introductory essay, we reflect on the significance of the re-election of Donald Trump to the presidency in the United States, and we provide some context for interpreting Trump's second term. Two of Trump's early policy moves—the release of billions of gallons of water from reservoirs in California and the granting of refugee status to Afrikaners—portend four years of politics based on alternative facts, conspiracy theories, and racial grievances. Trump's political agenda has received a significant boost from Silicon Valley billionaires, who are keen to eliminate regulatory bureaucracy. Paradoxically, while allied with high-tech futurists, Trump's policies hearken to an …

Stomatal Distribution And Post-Fire Recovery: Intra-And Interspecific Variation In Plants Of The Pyrogenic Florida Scrub, Genevieve Triplett, Aaron S. David

Faculty Publications

Premise

Amphistomy, the presence of stomata on both leaf surfaces, can increase photosynthesis yet is uncommon across vascular plants. The relative infrequency of amphistomy is often attributed to high costs, such as transpirational water loss. The Florida scrub—a hot, dry, shrub-dominated habitat—historically has experienced frequent fire, yet decades of anthropogenic suppression coupled with the reintroduction of prescribed burns has led to varied fire regimes. In this study, we investigated the links between amphistomy and fire with regard to the presence of the trait across species in this pyrogenic habitat and within-species variation before and after experimental fire and across a …
