Subjective Socioeconomic Status Moderates Self-Esteem Reactivity To Daily Stressor Exposure: Evidence From A Daily Diary Approach, Yi Jing Chua, Nadyanna M. Majeed, Verity Yu Qing Lua, Chi-Ying Cheng, Andree Hartanto

Research Collection School of Social Sciences

Research on self-esteem reactivity has demonstrated that self-esteem fluctuates in response to daily stressor exposure, and the strength of this relationship varies between individuals. Drawing upon the positive link between objective socioeconomic status (SES) and self-esteem, how subjective SES influences self-esteem reactivity to daily stressor exposure was explored. Using a 7-day daily diary study, the current study (N-participants = 243, N-days = 1651) adopted a multilevel analysis to demonstrate that subjective SES attenuated the within-person association between daily stressor exposure and daily self-esteem, even after controlling for demographics and objective indicators of SES. The interactions were also consistent across social …

A Lifespan Perspective On Positive Affect Fluctuations On Purpose In Life: Findings From A 9-Year Longitudinal Study, Jonathan L. Chia, Verity Y. Q. Lua, Andree Hartanto

Research Collection School of Social Sciences

Existing research has examined how static or average levels of positive affect (PA) influence purpose in life (PIL), but theoretical work suggests PA fluctuations may also play a role, potentially undermining PIL, especially in older adulthood. To this end, the present study examined the longitudinal association of PA fluctuations on PIL and the moderating role of age among 1,294 midlife and older adults in the United States, over a 9-year period (between 2004 and 2014). Results revealed a conditional effect of PA fluctuations on PIL – particularly among older individuals, and greater PA fluctuations were associated with a poorer sense …

Understanding The Physical Health Associations Of Intra-Individual Variability In Life Satisfaction Among Older Adults, Frosch Y. X. Quek, Kenneth Tan, David Chan

Research Collection School of Social Sciences

It is well established that inter-individual differences in life satisfaction positively predict health, but it is less clear how intra-individual variability in life satisfaction across time could influence health, particularly across individuals with different satisfaction levels. To address this gap, we analysed a large panel dataset from a national sample of 8,674 older adults, aged 50–70 (M = 59, SD = 5.42) in Singapore who completed surveys over 53 consecutive months. Results from multi-level modelling showed an interaction between variability in life satisfaction and life satisfaction mean on physical health.

The Effects Of The Chief Information Officer’S Presence And Tenure On Financial Performance, Xuemei Li

Theses and Dissertations in Business Administration

CIOs should be at the core of the organization. They play more and more critical roles in organizations. However, CIOs have not been paid enough attention in many firms. This can be partially observed in a lack of studies about CIOs, for instance, how CIOs influence the organizations, and how organizations' settings influence the CIOs. Technical initiatives or innovations may be the bridge between CIOs and firm performance. Different theories have been employed concerning CIOs, innovations, and firm performance. For instance, the resource-based view (RBV) has served as a theoretical foundation in related studies.

Drawing on RBV, attention-based view (ABV), …

Examining How Self-Regulated Learning Professional Development Affects Teacher Srl Knowledge, Beliefs, And Practices, Stephanie Greenquist-Marlett

STEMPS Theses & Dissertations

Self-regulated learning (SRL) strategies promote valuable student learning outcomes including academic achievement and lifelong learning (EU Council, 2002). Teachers have an opportunity to cultivate student SRL development within their classrooms (Azevedo et al., 2008). While teachers believe in the benefits associated with SRL promotion (Spruce & Bol, 2014), their positive attitudes are not often supported by adequate knowledge of SRL strategies. This leads to a lack of self-efficacy for developing SRL instruction in classrooms (Dignath & Büttner, 2018; Zimmerman et al., 1996). SRL-based professional development (PD) interventions have demonstrated their effectiveness for increasing teacher SRL instruction and implementation (Cleary et …

The Influence Of Monsoon Variability On The Circulation Of The Near-Surface Indian Ocean And The Depth-Integrated Chlorophyll, Marufa Ishaque

OES Theses and Dissertations

The Indian Ocean experiences a strong semiannual reversal of monsoon winds, which determines the weather and climate of Asia, including freshwater fluxes between the atmosphere, land, and ocean. Studies and model projections suggest that the timing and intensity of the seasonal monsoon have already started to change, with more dramatic changes likely in the future. However, the impact of these changes on the Indian Ocean circulation system, including the inter-basin salt/freshwater transport between the Bay of Bengal and the Arabian Sea, remains unclear. To better understand how monsoon variability affects Indian Ocean circulation patterns, a Regional Ocean Modeling System simulation …

Enhancing Data Usability For People With Visual Impairments, Yash Prakash

Computer Science Theses & Dissertations

Emotional Pathways To Trauma: Racialized Policing And Psychological Distress In Black Adolescent Males, Rochelle S. Parrish

All Theses

Introduction: Black American males, including adolescents, are disproportionately subjected to aggressive policing, often without criminal wrongdoing (Geller et al., 2014; Sewell et al., 2016). These encounters are frequently described as traumatic, marked by fear, loss, and emotional disruption (Smith Lee & Robinson, 2019). Whether direct or vicarious, such experiences can produce lasting psychological effects, particularly among Black boys who face compounded vulnerability from racialized surveillance and community-level trauma (DeVylder et al., 2018; Smith & Patton, 2016). Proactive policing tactics, such as investigatory stops and verbal aggression, have been linked to symptoms consistent with post-traumatic stress disorder (PTSD), including hypervigilance, avoidance, …

Optimal Quantization For Nonuniform Discrete Distributions, Russel Cabasag, Samir Huq, Eric Mendoza, Mrinal Kanti Roychowdhury

School of Mathematical & Statistical Sciences Faculty Publications

This paper explores the process of optimal quantization for several types of discrete probability distributions. Quantization is a technique used to approximate a complex distribution with a smaller set of representative points, which is important in fields such as data compression and signal processing. We begin by examining two specific nonuniform distributions over a finite set of values and identify the best representative points for different levels of approximation. We then extend our analysis to two infinite discrete distributions: one supported on the reciprocals of natural numbers and another on the natural numbers themselves. For these distributions, we compute the …
