Sustainability In Global Shrimp Supply Chains, Michael Behr

Sustainable Supply Chain Management

This chapter explores sustainability challenges within the global shrimp supply chain, comparing the environmental impacts of wild-caught shrimp trawling and shrimp aquaculture. While trawling has historically met global demand, its high levels of bycatch and damage to marine ecosystems make it increasingly incompatible with modern environmental standards. In response, aquaculture now supplies more than half of global shrimp production and is becoming a preferred sourcing option for major buyers.

From a supply-chain perspective, the chapter examines how trade dependence, regulatory pressure, and ESG commitments are shifting procurement strategies toward farmed shrimp. Using examples from large retailers, it shows how buyer-driven …

Assessing A Model Of Customer Rage: Does Customer Entitlement Moderate Relationships Between Rage Emotions, Expressions And Behaviors?, S. Mostafa Rasoolimanesh, Martin Gannon, Babak Taheri, Josip Mikulić

Research outputs 2022 to 2026

Across travel and tourism services research, studies investigating “customer rage” typically prioritize the direct point-of-consumption, often within airport, airline, or hotel contexts. However, the sector is awash with intermediaries (e.g., travel agencies, insurance brokers, booking platforms), which serve as primary points-of-contact capable of shaping customer expectations. Accordingly, the consequences of service failure therein are nuanced and complex. Yet, extant research often portrays service failure as unilateral (i.e., solely the firm in question’s responsibility), overlooking one core demand-side characteristic: the customer’s sense of entitlement. Thus, while this study draws upon the Iranian travel agency setting (as a service intermediary) to assess …

Iraqi Journal for Computer Science and Mathematics

Although 3D face generation is extensively studied in computer vision, most existing methods prioritize reconstructing 3D geometry from available 2D or 3D inputs rather than generating novel faces directly from latent representations. To bridge this gap, we present the application of Adversarial Volumetric Convolutional Neural Networks (AVCNN), a tailored adaptation of the vanilla 3D Generative Adversarial Network (3D-GAN), to 3D face generation using latent space Gaussian embeddings. We first assemble a custom 3D facial dataset to provide the requisite facial characteristics and to ensure sufficient coverage of geometric variation across identities. The generator, implemented as a decoder, maps latent space …

A Mixed Methods Exploration Of Autistic Adults' Leisure Experiences, Sevia Raelson, Otr/L

Post-Professional Occupational Therapy Doctorate Culminating Presentations

Introduction: Across ages and populations, leisure participation is essential to humans and associated with improved well-being, and both mental and physical health (Bishop-Fitzpatrick et al., 2017; Coster & Khetani, 2008; Lapa, 2013). The American Occupational Therapy Association [AOTA] formally defines leisure as intrinsically motivating, non-obligatory, self-chosen, and enjoyable activities done in one’s free time (AOTA, 2020). Leisure participation trends for autistic populations are better understood in pediatric populations than adults, but studies rely on neurotypically defined leisure activities. Given the differences between neurotypical and neurodivergent brains, it is likely that leisure activities are experienced differently by autistic adults; thus, …
