DLSU Business & Economics Review

The paper’s base reference is Duffee (1998). He examined the inverse relationship between the U.S. Treasury bill yields (TBY) and the corporate bond yield spreads (CBYS). Eight years of historical data on the Philippine CBYS from 2012–2019 and data on TBY were analyzed using OLS regression. To examine, if the results hold in the Philippines and given that the bond market in the country differs from the U.S. bond markets, will the results of Duffee (1998) persist? Although the paper focused on providing evidence on one of the most basic, well-established inverse relationships between TBY and inflation to CBYS, the …

The Influence Of Unhelpful Supervisor Support On Employee Burnout Across Cultures, Charles Blomstrom-Johnson Jul 2024

The Influence Of Unhelpful Supervisor Support On Employee Burnout Across Cultures, Charles Blomstrom-Johnson

Theses and Dissertations

Organizations continue to become increasingly interconnected globally, yet often fail to consider the cultural context of policies. Such failures to account for cultural differences may add to workplace stressors for employees, leading to an increased risk of burnout. Supervisors may attempt to buffer against burnout by providing social support to their employees. However, if the support given by supervisors is considered by the recipient to be unhelpful, these buffering effects may be reversed. Examining samples from the United States and Japan, this study hypothesized that unhelpful supervisor support and burnout would relate significantly to one another, and that culturally based …

The Role Of Executive Function In Cognitive Reappraisal: A Meta-Analytic Review, Wei Xing Toh, Jun Sheng Keh, James J. Gross, Laura L. Carstensen

Research Collection School of Social Sciences

Cognitive reappraisal refers to the reinterpretation of a situation to alter its emotional meaning. Theoretically, executive functions (EFs), such as inhibition, updating, and shifting, are core elements of reappraisal processes. However, empirical studies have yielded inconsistent evidence as to whether and to what extent EFs are associated with reappraisal. To address this issue, we conducted a meta-analysis of the literature in which 179 effect sizes from 59 independent samples (N = 4,703) were included. Using random-effects metaregression with robust-variance estimates and small-sample corrections, we also examined whether variation in effect sizes could be accounted for by potential moderators, such as …

How People Prompt Generative Ai To Create Interactive Vr Scenes, Setareh Aghel Manesh, Tianyi Zhang, Yuki Onishi, Kotaro Hara, Scott Bateman, Jiannan Li, Anthony Tang

Research Collection School Of Computing and Information Systems

Generative AI tools can provide people with the ability to create virtual environments and scenes with natural language prompts. Yet, how people will formulate such prompts is unclear---particularly when they inhabit the environment that they are designing. For instance, it is likely that a person might say, "Put a chair here,'' while pointing at a location. If such linguistic and embodied features are common to people's prompts, we need to tune models to accommodate them. In this work, we present a Wizard of Oz elicitation study with 22 participants, where we studied people's implicit expectations when verbally prompting such programming …

Augmenting Decision With Hypothesis In Reinforcement Learning, Minh Quang Nguyen, Hady Wirawan Lauw

Research Collection School Of Computing and Information Systems

Value-based reinforcement learning is the current State-Of-The-Art due to high sampling efficiency. However, our study shows it suffers from low exploitation in early training period and bias sensitiveness. To address these issues, we propose to augment the decision-making process with hypothesis, a weak form of environment description. Our approach relies on prompting the learning agent with accurate hypotheses, and designing a ready-to-adapt policy through incremental learning. We propose the ALH algorithm, showing detailed analyses on a typical learning scheme and a diverse set of Mujoco benchmarks. Our algorithm produces a significant improvement over value-based learning algorithms and other strong baselines. …
