Breaking Point: Exploring Side Bets, Support, And Pension Investment As Predictors Of Turnover Intention In Urban Policing, Kenneth M. Quick, Kevin T. Wolff

Publications and Research

Guided by Becker’s side-bet theory, this study examines turnover intentions among officers in the New York City Police Department by assessing pension investment and affective commitment as accumulated organizational “side bets,” alongside job satisfaction, perceived organizational support, and workplace conditions. Data was drawn from an online survey of 1,454 officers. Population weights based on gender, race/ethnicity, and rank were applied to improve representativeness. Weighted multinomial logistic regression models examined predictors of turnover intention, while second-difference tests of average marginal effects (AMEs) assessed whether workplace factors operated differently across tenure groups. Results indicate that perceived organizational attitudes and workplace conditions significantly …

Objective: Cancer survivors, defined as those living with or beyond a cancer diagnosis, experience more than double the prevalence of psychopathology when compared to the general population. Categorical diagnostic systems, such as the Diagnostic and Statistical Manual of Mental Disorders (DSM), remain dominant in psycho-oncology despite concerns about reliability, validity, and clinical utility for this population. Dimensional frameworks, such as the Hierarchical Taxonomy of Psychopathology (HiTOP), offer a more precise alternative; however, they have not yet been widely applied in cancer survivors. Accordingly, the objective of this research was to examine the applicability of HiTOP to cancer survivors. Methods: Data …

More Than Just Fair: Legitimizing Ai Through Reciprocity, Ethical Ai Characteristics And Personal Information Sharing, Shahid Hussain, Asim Qazi, Violetta Wilk

Research outputs 2022 to 2026

This research examines how perceived reciprocity and perceived ethical AI characteristics – fairness, accountability, and transparency (FAT principles) – shape consumers’ willingness to share personal information and its downstream consequences in AI-mediated consumer-brand interactions. Grounded in social exchange theory, we conceptualize personal information sharing as a behavioral gateway through which ethical exchange cues translate into perceived algorithmic legitimacy and intention to co-create value. Using a two-study design, consisting of a scenario-based experiment (n = 184) and a cross-sectional survey (n = 612), the findings of this research show that reciprocity and FAT principles robustly increase willingness to share personal information. …

Human Genetics Publications

Background: Polygenic risk scores (PRSs) improve prediction of the development of type 2 diabetes over the use of clinical risk factors alone; however, they perform poorly in populations of non-European ancestry, limiting their global clinical utility. We aimed to deliver comprehensive and rigorously tested multi-ancestry PRSs for prediction in type 2 diabetes.

Methods: We conducted meta-analyses using data from type 2 diabetes genome-wide association studies (GWAS) across cohorts from five major global ancestries: European, African or African American, Admixed American, South Asian, and East Asian. We used summary statistics from the GWAS to construct single-ancestry PRSs (using the continuous-shrinkage PRS-CS …

Skilful Attacking Trades Off With Defensive Ability In Hermit Crabs, Joshua Le Pla, Sarah M. Lane, Mark Briffa

School of Biological and Marine Sciences

The ability to win contests is crucial for securing the valuable resources individuals need to survive and reproduce. Fighting ability can thus be a vital determinant of fitness, and much research has been carried out to characterize the traits that influence fighting ability, or resource-holding potential (RHP). RHP is known to be influenced by a wide range of traits including morphology, physiology, vigour and, more recently, skill. These traits are typically analysed in isolation to identify their individual contributions to winning fights. However, relatively little is known about how different RHP traits may interact and potentially trade off against one …

Weathering In-Beyond Hydro(S)Cenes, Bronwyn Bailey-Charteris, Kathryn Mcmahon, Mary Christina Rapp, Natalie Davey

Research outputs 2022 to 2026

This paper examines the cultural, ecological and political dimensions of the contemporary water crisis through a curatorial and environmental humanities lens. Through the watery conceptual epoch of the Hydrocene, it highlights the work of artists and interdisciplinary practitioners whose hydro-Artistic methods propose ways to realign human-water relations. Central to this analysis is the role of curatorial care, here understood as a practice of convening, holding and enabling reciprocal encounters between bodies of water, artists and communities. Bringing these diverse practices into dialogue, the paper proposes water not only as subject matter but as a potential collaborator and leaky agent. It …

Basil Bernstein, Open Concepts, And The Possibility Of Change: Basil Bernstein, Conceptos Abiertos Y La Posibilidad Del Cambio, Brian Barrett, Jim Hordern

School of Law, Humanities and Social Sciences

In this reflection we make the argument that Bernstein’s theory offers an exceptionally powerful resource for analyzing social systems such as education, which critical realists as well as Bernstein have described in similar ways as “open.” Bernstein’s work has two significant features that contribute to this power, namely its capacity to conceptualize deep structures and organizing principles of education, teaching, and learning, as well as the possibilities it opens for imagining and accounting for alternatives and change through “open concepts.” Bernstein’s work is thus especially valuable both for analyzing 10educational inequality as well as for developing and testing measures for …

Research Outputs: 2025-Present

Synthetic biology has evolved from a set of engineering aspirations to an operationally sophisticated discipline, and artificial intelligence (AI) is its fastest-growing accelerant. This review traces that convergence across six interlocking domains: systems-level biological modeling, de novo protein engineering, metabolic and microbial programming, multi-omics data integration, regulatory element design, and clinical translation. For each domain, we survey established results, integrate findings from 2010–2026 literature, and articulate the trajectories that will define the next decade. Emerging themes include physics-informed neural networks for mechanistically constrained biological modeling, drug design, and federated learning architectures that allow global omics collaboration without centralizing sensitive data, …

Vehicle Autonomy To Ecosystem Intelligence: A Systematic Review Of Dynamic Vision Architectures In Surface Mining Operations, Nana Yaa Damtewaa Anti, Samuel Frimpong, Muhammad Azeem Raza

Mining Engineering Faculty Research & Creative Works

Autonomous Haulage Systems (AHS) have significantly transformed surface mining operations by improving safety, productivity, and operational consistency. Currently, AHS predominantly rely on vehicle-centric perception architectures. Onboard LiDAR, radar, cameras, and Global Navigation Satellite Systems (GNSS) perform sensing, interpretation, and decision-making within individual systems. These processes enable collision avoidance and path tracking. However, they are limited in their ability to consider the broader, dynamic mining environment characterized by dust, terrain degradation, geotechnical instability, heterogeneous traffic, and rapidly evolving operational conditions. This paper presents a systematic review of dynamic vision systems of AHS in surface mining. It critically analyzes the transition from …

Finite-Temperature Grain-Boundary Segregation In High-Entropy Carbides, Marium M. Mou, Tarek Md Anamul Haque, Samuel E. Daigle, Josiah Roberts, William G. Fahrenholtz, Jon Paul Maria, Douglas E. Wolfe, Eva Zurek, Stefano Curtarolo, Donald W. Brenner

Materials Science and Engineering Faculty Research & Creative Works

High-entropy carbides are promising candidates for extreme-temperature environments, but their grain-boundary chemistry remains difficult to resolve because segregation involves both chemical disorder and finite-temperature configurational sampling. Here, we quantify temperature-dependent grain-boundary segregation in high-entropy carbides using a universal message-passing atomic cluster expansion (MACE) machine learning interatomic potential combined with a hybrid Monte Carlo–molecular dynamics workflow. A 53.1 (Formula presented.) (Formula presented.) symmetric tilt grain boundary was sampled for six representative high-entropy carbide compositions containing group IV, V, and VI transition metals at 300 and 2000 K. Element-resolved metal-sublattice composition profiles reveal composition-dependent segregation modes. Several chemistries exhibit selective near-boundary enrichment …
