Corporate Governance And Firm Performance: Evidence From Political Instability, Political Ideology, And Corporate Governance Reforms In Pakistan, Irfan Haider Shakri, Jaime Yong, Erwei Xiang

Research outputs 2022 to 2026

We examine impact of corporate governance on firm performance following the implementation of the changes to the Code of Corporate Governance of Pakistan in 2012. Our sample period from 2008 to 2022 include periods of political instability and shifts in Pakistan's political landscape, providing an opportunity to examine the effectiveness of corporate governance mechanisms in enhancing accounting- and market-based firm performance measures. We find significant improvements attributed to reforms in the regulatory framework surrounding corporate governance practices particularly from expanded scope and composition of boards and audit committees. This led to broader capabilities and effective controls, thus improving firm performance …

Research outputs 2022 to 2026

Introduction: Western Australia has one of the highest rates of Aboriginal children entering out-of-home care in Australia. Kinship care is the preferred culturally safe out-of-home care option for Aboriginal children, yet all jurisdictions, including Western Australia, are far from meeting best-practice national standards. Intersectoral collaboration is a key primary healthcare principle and internationally recognized for improving health systems and outcomes. This paper presents findings from a qualitative research project investigating Aboriginal primary healthcare workers’ experiences of intersectoral collaboration challenges and strengthening opportunities. Methods: Constructivist grounded theory guided this research involving 55 semi-structured interviews and four focus group discussions with Aboriginal …

Research outputs 2022 to 2026

Short-chain fatty acids (SCFAs) hold exert many nutritional benefits on both physiological and pathological processes, including host metabolism, immune modulation, and appetite control. Originating from the microbial fermentation of resistant starches and dietary fibre in the colon, SCFAs have the capability to traverse the blood–brain barrier (BBB). It is evident that SCFAs play a critical role in the development of neurodegenerative disorders such as Alzheimer's disease (AD). AD is the most common form of dementia and is characterised by the deposition of amyloid β peptides (Aβ) and tau hyperphosphorylation. SCFAs have demonstrated the potential to interfere with the protein–protein interactions …

Students' Preferences For Setting And/Or Mixed-Ability Grouping In Secondary School Physical Education In England, Shaun D. Wilkinson, Dawn Penney Jan 2024

Students' Preferences For Setting And/Or Mixed-Ability Grouping In Secondary School Physical Education In England, Shaun D. Wilkinson, Dawn Penney

Research outputs 2022 to 2026

There is an extensive international literature on different forms of ability grouping in schools, much of which describes their impact on students' academic achievement, motivation, self-concept and/or attitudes towards learning. Comparatively little research has focused on students' perspectives of these practices, while the research that has been conducted has primarily focused on mathematics, English and science. There is a conspicuous and arguably significant absence of research that explores students' perspectives on different forms of ability grouping in other areas of the school curriculum, including physical education (PE). In contrast to the relative privacy of classroom-based subjects, students' bodies, physical competencies …

Will Return-To-Office Mandates Prevent Proximity Bias For Employees Working From Home?, Sue Williamson, Uma Jogulu, Judy Lundy, Helen Taylor Jan 2024

Will Return-To-Office Mandates Prevent Proximity Bias For Employees Working From Home?, Sue Williamson, Uma Jogulu, Judy Lundy, Helen Taylor

Research outputs 2022 to 2026

This Practice and Policy article examines return-to-office mandates, the latest human resource controversy. These mandates are an organisational directive for employees who have been working from home to return to working in their employer's premise. Drawing on the literature and our research on working from home and hybrid working, we consider whether mandates may prevent proximity bias. We conclude that mandates requiring employees to return to the office or caps which limit working from home are not only unnecessary, but may have negative consequences. In particular, mandates may cause employee resentment, while caps limit flexibility and autonomy. We therefore do …

Research outputs 2022 to 2026

Reduced brain volumes and more prominent white matter hyperintensities on MRI scans are commonly observed among older adults without cognitive impairment. However, it remains unclear whether rates of change in these measures among cognitively normal adults differ as a function of genetic risk for late-onset Alzheimer's disease, including APOE- ε4, APOE-ε2 and Alzheimer's disease polygenic risk scores (AD-PRS), and whether these relationships are influenced by other variables. This longitudinal study examined the trajectories of regional brain volumes and white matter hyperintensities in relationship to APOE genotypes (N = 1541) and AD-PRS (N = 1093) in a harmonized dataset of middle-aged …

Infrared Ship Segmentation Based On Weakly-Supervised And Semi-Supervised Learning, Isa Ali Ibrahim, Abdallah Namoun, Sami Ullah, Hisham Alasmary, Muhammad Waqas, Iftekhar Ahmad

Research outputs 2022 to 2026

Existing fully-supervised semantic segmentation methods have achieved good performance. However, they all rely on high-quality pixel-level labels. To minimize the annotation costs, weakly-supervised methods or semi-supervised methods are proposed. When such methods are applied to the infrared ship image segmentation, inaccurate object localization occurs, leading to poor segmentation results. In this paper, we propose an infrared ship segmentation (ISS) method based on weakly-supervised and semi-supervised learning, aiming to improve the performance of ISS by combining the advantages of two learning methods. It uses only image-level labels and a minimal number of pixel-level labels to segment different classes of infrared ships. …

Levels Of Unrelated Diversification And Firm Performance: A Conceptual Description Of An S-Shaped Hypothesis, Kwaku Alex Gyan

Research outputs 2022 to 2026

This study reconceptualizes the so far inconclusive relationship between unrelated diversification and financial performance by explaining how coordination costs can shape the amount of free cash flow and related agency problems at different levels of unrelated diversification. The study builds upon the notion that coordination requirements and associated coordination costs will vary at levels of unrelated diversification to regulate the amount of free cash flow managers will have at their disposal at each level of unrelated diversification. Based on the agency costs associated with free cash flow, we conceptualize that at different stages of unrelated diversification, the degree of managerial …
