Ethnic Dissimilarity, Ethnic Status, And Organizational Embeddedness: Climate For Inclusion As Double-Edged Sword, Debjani Ghosh, Jorge A. Gonzalez, Daan Van Knippenberg, Richard A. Rodriguez

Management Faculty Publications

Ethnic dissimilarity to coworkers puts individuals’ social embeddedness at work under pressure. We consider this issue from the perspective of a moderating influence of climate for inclusion in the relationship between ethnic dissimilarity and organizational embeddedness. We argue that, whereas it may seem straightforward that climate for inclusion would be associated with a weaker negative influence between ethnic dissimilarity and organizational embeddedness, team climate for inclusion is a double-edged sword. Taking the status associated with ethnic groups into account, we propose that the status equality implied by climate for inclusion has differential effects for members of high ethnic status and …

Dual Self-Construal Integration (Dsci) And Romantic Relationships In Singapore: Enhancing Romantic Relationship Satisfaction Through Creativity, Kenneth Tan, Chi-Ying Cheng, Gloria J. Lai, Daniel Ho

Research Collection School of Social Sciences

Research has shown that independent vs. interdependent self-construals are largely shaped by culture and can predict the endorsement of distinct relational schemes when dealing with close others. Intriguingly, individuals exposed to both Eastern and Western cultures can develop both independent and interdependent self-construals and possess the two seemingly conflicting self-construals simultaneously. What is less explored is how different management of both independent and interdependent self-construals influence individuals' navigation of relational schemas in their romantic relationships. The current research examines the influence of how one's dual self-construal integration (DSCI)—an individual difference measure that captures the degree to which individuals perceive independent …

Secondary School Students' Engagement In Learning Activities: Validation Of A Short Scale, Feliciano Henriques Veiga, Zi Yang Wong, Johnmarshall Reeve, Shane Jimerson, Antonio Leite, Joan Perales, Sonia Valente, Isabel Martinez

Research Collection School of Social Sciences

Student engagement is a multidimensional construct strongly associated with learning outcomes and academic success. However, its measurement remains challenging, as existing instruments often conflate engagement in learning activities with engagement in the school community. In addition, brief measures are scarce despite their increasing value, and most available instruments do not incorporate agentic engagement. Assessing student engagement in learning activities is, therefore, crucial for monitoring academic progress, identifying students at risk of dropping out, and predicting academic success. This study aimed to validate the 12-item Secondary School Student Engagement in Learning Activities: Short Scale, adapted from a higher education measure, which …

Humanitarian Hospitality: A Framework For Ethical Encounters In Crisis Tourism, Georges El Hajal, Rodney Westerlaken, Erwin Losekoot

Research outputs 2022 to 2026

This paper introduces humanitarian hospitality as a conceptual framework for understanding relational ethics and care practices in crisis-affected tourism. While volunteer tourism, disaster recovery travel, and solidarity-based travel bring individuals into crisis-affected destinations, the hospitality that unfolds in these non-commercial encounters remains under-theorised. Drawing on philosophical perspectives and exploratory qualitative insights from 145 Red Cross and Red Crescent volunteers and aid workers, the study examines how emotional labour, ethical care, and informal hosting are enacted in contexts of conflict and displacement. The findings both parallel and complicate conventional host–guest dynamics, highlighting the ethical and emotional complexities of providing care under …

Longevity, Resilience, And Thriving Of Women In Ministry: A Case Study Of Women In Ministry From A United Pentecostal Holiness Church, Eunice Cheryl Feltus Little

Electronic Theses and Dissertations

Abstract

The problem of ministry attrition caused by burnout is well documented. Research attributes the impact of burnout on the resilience, longevity, and thriving of ministry workers to role-related stress and adversity. High attrition rates throughout religious organizations and a lag in longevity and resilience contribute to a shortage of ministry workers. Some ministry workers leave the vocation because of stress and burnout, yet others persevere. Despite the possible adverse effects, many men and women find a sense of well-being and joy in ministry work. This qualitative distributive case study focused on those who stayed in ministry and the strategies …

Leader Rounding For Outcomes To Improve Employee Retention, Laura R. Escobar

Leadership Styles And Their Impact On Employee Engagement, Commitment, And Satisfaction In Non-Profit And For-Profit Organizations, Laure-Ann Swaby

JWU Dissertations & Theses

As organizations face challenges in sustaining retention and development, they must analyze and implement strategies to strengthen their workforce (Hassanein & Özgit, 2022). Employees are a company's greatest asset; without them, production would halt, as their knowledge, skills, and abilities drive organizational performance and operations (Chunhui et al., 2004; Gallup, 2023). Sturm and Vera (2011) showed that employees tend to be less committed when factors such as desired leadership styles, engagement, and job satisfaction are negative within an organization. Over the past decade, turnover has increased significantly, imposing financial challenges to organizations across both the non-profit and for-profit sectors (McCrory …

Engineering Enac Constructs To Examine Pip2 And Ubiquitin Competition On Enac Regulation And Stability, Lacie Johnson

Chemistry & Biochemistry Undergraduate Honors Theses

The epithelial sodium channel (ENaC) plays a critical role in sodium homeostasis, fluid balance, and blood pressure regulation. ENaC activity is tightly controlled by post-translational mechanisms, including ubiquitination-mediated degradation and phosphatidylinositol 4,5-bisphosphate (PIP2) dependent channel activation. PIP2 is a phospholipid necessary to facilitate the maximal channel opening. Previous studies suggest that intracellular PIP2 binding sites are located in proximity to ubiquitination sites on ENaC subunits, raising the possibility of PIP2 binding to influence channel stability and function. This thesis aimed to engineer and validate molecular tools capable of examining the interplay between PIP2 binding and ubiquitination in ENaC regulation. A …

Uncertain Search With Knowledge Transfer, Woonghee Tim Huh, Michael Jong Kim, Meichun Lin

Research Collection Lee Kong Chian School Of Business

We consider a sequential search over a group of similar alternatives. The individual value of an alternative contains two components, an observable utility and an idiosyncratic value. Observable utilities share an unknown population distribution, which captures the similarity across the alternatives and allows for knowledge transfer within the group. Once a decision maker encounters an alternative, its utility is revealed immediately, whereas the idiosyncratic value is unobservable and needs to be learned by sampling. The goal is to select an alternative with the highest individual value while accounting for the sampling and search costs. A novel feature of this problem …

Faculty, Staff and Student Publications

Sleep dysfunction is common among individuals with schizophrenia spectrum disorders (SSD). Sleep duration and other sleep quality metrics are associated with worse patient clinical and social outcomes. We examined if accumulative stress, gray matter structural volume measured with high-resolution structural brain MRI, diffusion tensor imaging measures of white matter microstructure, and psychopathology (for the schizophrenia group) may act as predictors of sleep quality and compared individuals with SSD (N = 101) and healthy controls (N = 86). We created an adjusted Pittsburgh Sleep Quality Index (PSQI-A) score to measure sleep quality and account for abnormally long sleep duration as dysfunctional. …

Background: Proinflammatory cytokine production may be related to poor emotional adjustment in dementia spousal caregivers. People who display attachment insecurity may be at increased risk for adverse caregiving experiences and poor psychosocial outcomes.

Objective: This study aimed to understand whether proinflammatory cytokine production was associated with anticipatory grief, caregiver burden, and depressive symptoms and whether those relationships were stronger for caregivers higher on attachment anxiety or avoidance.

Method: A sample of 103 dementia spousal caregivers provided self-report data on demographics, health information, and psychosocial outcomes. We also determined lipopolysaccharide-induced whole-blood interleukin-6, interleukin-1β, tumor necrosis factor-α, and interleukin-10 production and combined …

The Powerful Teacher: A Power Hypothesis For The Benefits Of Learning-By-Teaching, Sarah Shi Hui Wong, Stephen Lim

Research Collection School of Social Sciences

Why does teaching others enhance one's learning? This study advanced a novel power hypothesis of learning-by-teaching: When assuming the role of a teacher, students experience a heightened sense of power in influencing others, which increases their own learning. University students (N = 242) studied a scientific text using one of three learning methods: notetaking, explaining, or teaching. The notetaking group prepared to be tested and wrote study notes about the topic; the explaining group prepared to explain and wrote an explanation about the topic as how they would write a textbook for their peers; the teaching group prepared to teach …
