Investigating The Determinants Of Fight Dynamics In The Minotaur Beetle Typhaeus Typhoeus, Amy Bromley

School of Biological and Marine Sciences Theses

It is widely accepted that the main determinants of contest outcome are resource value, residency status, and resource holding potential, with each of these playing an important role in determining contest behaviour. Examples of resource holding potential are morphological traits such as body size and weaponry. Animals that possess weaponry can exhibit different morphotypes, such as size difference in horns, which can lead to differences in contest behaviour, with larger morphotypes engaging in head-to-head combat, while smaller morphotypes can avoid combat altogether. One such species that possess weapons in the form of horns and engages in physical combat, is the …

This study examined fish species diversity, richness, abundance, behaviour, and the time spent in coral habitats. The analysis encompassed seven coral genera in an Indo-Pacific reef system. Twenty 2 × 2 m reef areas, each dominated …

Trialing A Novel Method Of Skin Mucus Sampling To Measure Stress And Reproductive Steroid Hormones In Mobula Species Mobula Alfredi And Mobula Munkiana, Bethany Faulkner

School of Biological and Marine Sciences Theses

Anthropogenic pressures, exacerbated by exceptionally slow population growth, have led to all mobulid species being listed on the IUCN Red List. Understanding stress and reproductive physiology is essential for improving mobulid conservation strategies. However, few studies have investigated the hormonal processes that underlie stress responses and reproductive physiology in mobulids. Studies on fish species have identified positive correlations between steroid hormone concentrations in blood and skin mucus, the collection of the latter being a much less invasive technique. This pilot study examined the feasibility of using skin mucus as a non-invasive matrix for detecting steroid hormones in two mobulid species. …

Health Professions Education

Purpose This study aimed to assess the impact of a structured reflective practice intervention on the development of professional identity among nursing students. Method A mixed-methods design was adopted. The intervention, based on guided reflective practice, was implemented with a voluntary sample of 58 participants. The evaluation relied on a quasi-experimental quantitative approach using the Macleod Clark Professional Identity Scale, with a comparison group and both pre-test and post-test measurements. A qualitative component was also included to explore the dimensions of the studied concept in greater depth. Results Quantitative findings showed a statistically significant difference between the post-test means (p < 0.001), indicating that the reflective practice intervention had a positive effect on the experimental group compared to the control group. The qualitative results further illuminated students’ reflections, which were organized into ten themes corresponding to the study’s conceptual framework: professional knowledge and skills, values and ethics, the nursing role, leadership, professional self-image, social image of the profession, sense of belonging, identification with role models, theory–practice integration, and career choice. These dimensions provided a comprehensive and nuanced understanding of professional identity, capturing the complexity of the concept. Conclusion These results support the integration of reflective practice as a pedagogical approach to fostering the construction and development of a positive professional identity. Professional identity, as a rich and multidimensional concept, goes beyond the process of professionalization—it represents its ultimate achievement.

Deconstructing Parenthood: A Critical Queer Analysis Of Gender, Law, And Bionormativity In India, Jwalika Balaji

National Law School of India Review

Parenthood (the legal connection to one’s child) is often assumed to be a biologically determined and natural status, but in reality, it is a legal and social construct shaped by historical, cultural, and political contexts. This paper critically examines the legal framework of parenthood in India, highlighting how it privileges a bionormative, dyadic, heterosexual parental unit, while marginalising LGBTQ+ individuals, unmarried couples, and alternative family structures. Through a critical queer method, the paper deconstructs the bio-essentialist juxtaposition of gender, conjugality, and reproduction that underpins Indian family law. It explores how the legal framework selectively acknowledges the constructed nature of parenthood …

New Metrics For Disambiguating Feature Overlap And Catastrophic Forgetting In Incremental Learning Contexts, Niklas M. Melton, Leonardo Enzo Brito Da Silva, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

Catastrophic forgetting remains a central challenge in lifelong learning, where newly acquired knowledge interferes with previously learned tasks, degrading performance over time. Mitigation strategies such as rehearsal and regularization have been proposed, but both introduce limitations, either by retaining old data or by constraining model updates in ways that may impair learning. Complicating matters, recent findings show that feature-space overlap between tasks can produce similar performance drops even in models that memorize data, making it difficult to distinguish true forgetting from representational interference. Current accuracy-based metrics fail to disentangle these effects, undermining diagnostic clarity. In this work, we introduce the …
