The purpose of this study is to (1) improve the spectral features of the second-order uniformly non-oscillatory (UNO) slope limiters, and (2) numerical simulation of the unified-form of generalized fully-coupled saturated thermo-poro-elastic systems in the axisymmetric cylindrical coordinate via cell-adaptive Kurganov-Tadmor (KT) central high-resolution scheme using the UNO limiters.

(1) The spectral features of the UNO limiter are improved by compression-adaptive MINMOD (MM) limiters, achieved by blending different types of MM limiters to achieve less numerical dissipation and dispersion. These blended MM limiters preserve the total variation diminishing (TVD) feature over non-uniform non-centered cells. Also, the spectral features of the central schemes using the UNO limiters are investigated. (2) For the thermo-poro-elastic problem, corresponding first-order hyperbolic system is provided, including flux, source, diffusion and nonlinear terms. Where, there are different interacting components in the source and flux terms. The nonlinear terms are also considered by the Picard-like linearization concept.

Compression-adaptive UNO limiters would be stable over adapted cells with centered and non-centered cells. The benchmarks confirm that both spectral features and numerical accuracy are improved. For the generalized thermo-poro-elastic problem, corresponding responses including the shock waves can properly be captured.

Studying heat effects (e.g. hot fluid or freezing) and explosions on tunnels. Also, the UNO limiters could be used for simulations of various systems of conservation laws.

Introduction: Based on the given experiences, many government institutions failed in their strategic management and planning for managing COVID-19. Meanwhile, when a crisis disrupts a system, institutions lose their direction and fail to make necessary responses.

Purpose: The current study highlighted the impact of social justice and modern governance in providing equitable healthcare services and dealing with crises during the COVID-19 pandemic in developing countries.

Methodology: Cross-country analyses were used based on captured secondary data. We evaluated several indices, including, for example, Crisis Index Indicators, Worldometers, and the Global Health Security (GHS) Index 2019.

Findings: According to the GHS (2019) data, public health service delivery equity was ineffective, socially unjust, and unfair treatment was experienced in the context of the conflict-affected countries. Most conflict-affected countries (Iraq, Nigeria, Afghanistan, and Venezuela) did not have guidelines or public reports committing to providing prioritized healthcare services to the public and healthcare workers. The experience of conflict-affected countries has shown that healthcare disparities still exist. While many governments in conflict-affected countries failed to give equitable access to healthcare services during the COVID-19 pandemic to the public.

The purpose of this study was to investigate the impact of using a jigsaw learning strategy integrated with computer simulation (JLSICS) on the academic achievement and attitudes of students, along with exploring the relationships between them in the process of learning about acids and bases.

The research design used in the study was quasi-experimental, using non-equivalent comparison groups for both pre- and post-tests. A quantitative approach was used to address the research problem, with three groups involved: two experimental and one comparative group. The treatment group, which received the JLSICS intervention, consisted of two intact classes, while the comparison group included one intact class. Data collection involved achievement tests and attitude scale tests on acid and base. Various statistical analyses such as one-way analysis of variance, one-way multivariate analysis of variance, Pearson product-moment correlation, mean and standard deviation were used for data analysis.

The study’s results revealed that the incorporation of the JLSICS had a beneficial influence on the academic achievement and attitudes of grade 10 chemistry students towards acid and base topics. The JLSICS approach proved to be more successful than both conventional methods and the standalone use of the jigsaw learning strategy (JLS) in terms of both achievement and attitudes. The research demonstrated a correlation between positive attitudes towards chemistry among high school students and enhanced achievement in the subject.

The study only focused on one specific aspect of chemistry (acid and base chemistry), which restricts the applicability of the findings to other chemistry topics or subjects. In addition, the study used a quasi-experimental design with a pretest-posttest comparison group, which may introduce variables that could confound the results and restrict causal inferences.

This study addresses the gap in instructional interventions and provides theoretical and practical insights. It emphasizes the importance of incorporating contemporary instructional methods for policymakers, benefiting the government, society and students. By enhancing student achievement, attitudes and critical thinking skills, this approach empowers students to take charge of their learning, fostering deep understanding and analysis. Furthermore, JLSICS aids in grasping abstract chemistry concepts and has the potential to reduce costs associated with purchasing chemicals for schools. This research opens doors for similar studies in different educational settings, offering valuable insights for educators and policymakers.

The originality and value of this study are in its exploration of integrating the jigsaw learning strategy with computer simulations as an instructional approach in chemistry education. This research contributes to the existing literature by showing the effectiveness of JLSICS in improving students’ achievements and attitudes towards acid and base topics. It also emphasizes the importance of fostering positive attitudes towards chemistry to enhance students’ overall achievement in the subject.

The purpose of this paper is to provide a critical perspective on how the COVID-19 crisis shaped inclusive leadership behaviors of global business leaders.

Using quantitative and qualitative methods, the authors analyzed 240 CEO statements in 120 multinational enterprises from six countries (France, India, Japan, South Korea, UK, USA), pre- and mid-COVID-19.

Results show that CEO emphasis on inclusive leadership increased during the pandemic. More substantively, the authors identify three key behaviors of inclusive leadership – fidelity, calmness and collective resilience.

The authors provide empirical evidence of inclusive leadership behaviors by global business leaders. In doing so, the authors integrate inclusive leadership into societally engaged international business research.

The aim of this paper is to examine the construction of female beauty ideals in Tokalon advertisements in 1930s Sweden.

This paper uses the theoretical perspective of social semiotics and the methodology of multimodal critical discourse analysis to analyze a corpus of 91 Tokalon advertisements collected from the Swedish Historical Newspaper Archive.

The analysis indicates that women were encouraged to engage in beauty work practices to preserve the idealized white, youthful face. Working on and “perfecting” the female face was framed as a way for women to exercise their autonomy and emancipation. However, a closer analysis of the advertisements reveals that women’s empowerment was often measured in terms of securing male attention or finding a husband. Women who failed to enhance their appearance were positioned as at risk of being unloved and/or unmarried, while those who engaged in beauty work practices were rewarded with romantic success. Interestingly, however, the promotion of beauty practices was not rooted with traditional notions of the “male gaze”, but rather reflected an “autoerotic gaze” that emphasizes self-governance by modern women.

This paper demonstrates the significance of analyzing Swedish cosmetic advertisements from this period to understand their role in shaping constructions of femininity. It also highlights the important influence of American advertising styles and culture in Swedish advertising practices and how they helped shape beauty norms in Sweden.

Value constitutes a key principle of asset management (AM) and decision-making processes should be oriented toward optimizing it. Value models refer to models that can measure the effects of any decision over value, supporting decision-making concerning the assets through their whole lifecycle. In this context, the objective of this work is to develop a methodology for establishing value models to support decision-making in strategic capital investments for multi-category portfolios.

An approach that integrates multi-criteria decision-making, AM principles and participatory processes is proposed.

The analytic hierarchy process and multi-attribute utility methods are used as analytical tools enabling the assignment of absolute merits to the evaluated alternatives. The application of the AM principles allows one to frame the decision problem within the context of AM. Furthermore, participatory processes enhance transparency and trust in the developed value model and empower employees.

Through the application of a case study, it has been demonstrated that the approach not only facilitates the ranking of alternatives and a better understanding of their strengths and weaknesses but also establishes a shared concept of objectives (and attributes for their assessment) within the company for the capital investment decision-making.

The AM literature often lacks systematic approaches for identifying value and making value-based decisions. While some approaches have been proposed for guiding strategic capital investments, they typically rely solely on financial and risk criteria. This work aims to bridge this gap by integrating various dimensions of value into the development of a comprehensive value model.

This paper aims to explore the extent of corporate social responsibility disclosure (hereafter CSRD) in Jordan and also examine whether ownership structure, board of directors and audit committee characteristics influence CSRD.

The extent of CSRD is measured by constructing a CSRD index for industrial firms listed on the Amman Stock Exchange from 2016 to 2021. Panel regression analysis is used to examine the potential effect of ownership structure, board of directors and audit committee on the level of CSRD.

This study provides empirical evidence that diverse groups of shareholders have different effects on CSR engagement, and board characteristics (board size, board independence and gender diversity) play a vital role in increasing voluntary disclosure, including CSR information. There is no evidence to support that CSRD is influenced by audit committee characteristics.

This study recommends that corporate regulators and policymakers can improve CSRD practices by expanding the scope of existing disclosure requirements related to CSR and developing a structured CSRD index to measure the degree of CSRD practices for comparative purposes. Encourage firms to actively participate in social responsibility programs by granting tax incentives and government facilities to firms with the best CSR reports. Policymakers should introduce initiatives that support female’s representation on board. Finally, firms should restructure their boards by increasing board size and the percentage of independent directors to enhance their effectiveness to support CSRD.

This paper contributes further insights into the literature on CSRD practices and disclosure by analyzing data from developing market contexts.

The purpose of this paper is to investigate the comment letters (CLs) in the standard-setting process of audits of less complex entities (LCEs). The objective is to gain insight into the overall picture of the CLs and to report on areas where comment providers agree or disagree with IAASB's Part 10.

A content analysis of 60 comment letter (CLs) was conducted to investigate the suggested additional Part 10 on audits of groups' financial statements in the proposed ISA for LCEs. Hence, this study examines three specific topics: (1) the views related to the use of the International Standard on Auditing (ISA) for LCEs for group audits in which component auditors are involved, (2) the proposed group-specific qualitative characteristics to describe the scope of group audits and, finally, (3) insights into the content of the proposed Part 10 and related conforming amendments. The Gioia method is used to provide a holistic approach to concept development of the arguments about the new Part 10.

The CLs stated that, while the proposed Part 10 has some weak points, it still provides a solid and practical structure within which to undertake an LCE group audit and a promising basis for further development. For instance, when discussing the improvements, the CLs stated that Part 10 should allow for more auditor judgment when determining when the involvement of component auditors renders a group audit complex. In addition, the CLs asserted that professional judgment should be engaged when considering the qualitative characteristics and the complexity of the group.

This study contributes to the very scarce research about the ISA for LCEs and the role of lobbying in shaping the audit standard-setting process.

While extensive research has explored poverty in various dimensions, there remains a notable dearth of studies focusing on success stories of slum dwellers overcoming adversity. This research seeks to address this gap by investigating the strategies employed by individuals to transcend poverty. Moreover, it evaluates the practicality and effectiveness of existing theories in real-world contexts through careful interpretation.

Data were gathered from two distinct cases through comprehensive, in-depth interviews. These narratives were subjected to scrutiny employing the Description Analysis Interpretation method. Subsequent interpretation and theoretical exploration were guided by Bourdieu’s class theory. The overarching goal was to shed light on the remarkable journeys of specific slum residents who surpassed the constraints of poverty. This endeavor not only highlighted the practical efficacy of these theories but also underscored their relevance in illuminating real-world scenarios through interpretation.

The findings underscore the capacity of slum dwellers to rise above poverty, thereby emphasizing the practical utility of specific theories aimed at poverty alleviation in elucidating their experiences. Notably, social capital, a cornerstone of Bourdieu’s class theory, emerges as equally pivotal as economic capital in shaping individuals' trajectories.

The study’s scope is confined to narratives within the Colombo slums, offering a platform for future researchers to extend their investigations beyond this context. By employing alternative methodologies and exploring diverse geographical regions, scholars can broaden their understanding of poverty alleviation strategies and their applicability across varied socioeconomic landscapes. This calls for wider research for comprehensive exploration and comprehension of poverty dynamics beyond singular locales.

The study provides invaluable insights for policymakers, governmental bodies and nongovernmental organizations, urging them to reconsider and reformulate policies, educational strategies and community development programs tailored to the needs of slum dwellers and their children. These insights offer a pathway toward more effective interventions aimed at fostering sustainable upliftment within these marginalized communities.

This research fills a critical gap in poverty literature by exploring success stories of slum dwellers overcoming adversity, an area often overlooked. It uniquely investigates the strategies these individuals employ to transcend poverty, offering fresh insights into the practical application of poverty alleviation theories. Utilizing Bourdieu’s class theory, the study highlights the importance of both social and economic capital in these success narratives. By focusing on real-life experiences, it underscores the relevance and utility of these theories in real-world contexts, enriching the theoretical discourse and providing valuable perspectives for policymakers and practitioners.
