Higher-Order Moment Risk Spillovers Between The Carbon And Energy Markets Under Climate Policy Uncertainty, Qiang Ji

Double Helix Methodology

Against the backdrop of increasing climate policy uncertainty, preventing cross-market risk contagion in the energy transition is crucial to ensuring energy security and effective risk management. First, this study uses the generalized autoregressive conditional heteroskedasticity-skewness-kurtosis (GARCHSK) model to measure the higher-order moment risk of the carbon and energy markets. Then, based on the quantile spillover index model, the higher-order moment risk spillover effects and their time-varying characteristics in different risk states are characterized. Furthermore, the climate policy uncertainty index (CPU) is incorporated into the generalized autoregressive conditional heteroskedasticity-mixed data sampling (GARCH-MIDAS) model to analyze its impact on higher-order moment risk …

Interpersonal Satisfaction And Classroom Silence In Chinese Universities: The Mediating Role Of Social Anxiety, Siguang Zhang

Double Helix Methodology

Introduction: Within Chinese universities, classroom silence, while culturally acceptable, may indicate underlying psychological distress that impedes academic engagement. Drawing upon social-cognitive theory, this study investigates whether social anxiety mediates the relationship between interpersonal satisfaction and students’ in-class silence. Methods: A cross-sectional survey of 565 undergraduates from six Chinese universities examined interpersonal satisfaction, social anxiety, and three distinct behavioral indicators of silence (large-lecture, small-discussion, and laboratory contexts). Confirmatory factor analysis established convergent and discriminant validity; Cronbach’s α coefficients ranged from 0.86 to 0.91, demonstrating good internal consistency. A structural equation model (SEM) was employed to test the hypothesized mediation pathway while …

Evolving Skills And Stakeholder Dynamics: Investigating The Transformative Influence Of Generative Ai On Egyptian Public Policy, Zeinab Hosny Abdelgawad

Theses and Dissertations

Since its public release in November 2022, OpenAI's Generative AI (GenAI) has been met with varied responses, from widespread individual adoption to institutional caution. This phenomenon is evident among Egyptian public policy makers, where some institutions quickly embraced GenAI, while others have been slow to integrate it. The adoption of GenAI among these professionals is influenced by multiple factors, with institutional factors and budget constraints being the most significant. The varied adoption creates a need for new skills and the enhancement of existing ones. This uneven adoption is hypothesized to cause two main issues in Egyptian public policy: a policy …

Domestic Violence Againts Women In Thailand: Galtung-Based Analysis Of Violence In Thai Drama “Tie Me (K)Not”, Akhdiat Dimas Abimanyu, Rahadjeng Pulungsari

International Review of Humanities Studies

This study examines the portrayal of domestic violence against women in the Thai drama Tie Me (K)not (2022) using Johan Galtung’s theory of violence, which categorizes violence into direct, structural, and cultural forms. Through qualitative content analysis, the research identifies how the drama depicts these forms of violence, reflecting broader societal issues in Thailand. The findings reveal explicit instances of direct violence, such as physical and psychological abuse, systemic structural violence through institutional failures in justice and support systems, and cultural violence rooted in patriarchal traditions that justify gender inequality. The drama not only highlights these oppressive dynamics but also …

Reachability In Interactive Chemical Reaction Networks, Aberto Avila-Jimenez, Bin Fu, Elise Grizzell, Robert Schweller, Tim Wylie

Computer Science Faculty Publications

This paper studies the effects of interactivity on molecular computation, specifically in the Step Chemical Reaction Networks model (Step CRNs), by adding the ability for a user to interact with the system by selecting which species to add at each step, or by having some control over which reactions execute. The two proposed variants are Interactive CRNs and Randomized Interactive CRNs. We show that in Interactive CRNs, even when restricted to void (deletion-only) rules of relatively small size, if a user can decide which species to add at each step based on the configuration, reachability is PSPACE-complete when bounded and …

A Bim-Based Flexible Flow Shop Framework For Scheduling Linear Infrastructure Projects, Mahmoud Mohamed Elbassuony

Theses and Dissertations

Repetitive, multi-stage linear projects, such as pipelines or highways, are primarily impacted by spatial and resource constraints during their execution. Cost overruns, delays, and inefficient resource allocation make construction management for such projects complex. Traditional scheduling techniques, such as Critical Path Method (CPM) and Line of Balance (LOB), are less efficient for scheduling dynamic, complex, and multi-objective projects. There are more advanced scheduling methods that can be applied as a decision-making process to determine the optimal timing of activities and achieve other objectives. One of those techniques is the Flexible Flow Shop model (FFS), which can be effectively applied to …

Keeping It Together: Assessing The Wellbeing Of Project-Based Development Practitioners In Egypt, Amira Ahmed Abdallah Fekry Ahmed
