Concrete-filled double skin tube (CFDST) columns are considered one of the most effective steel-concrete composite sections owing to the higher load carrying capacity as compared to its counterpart concrete-filled tube (CFT) columns. This paper aims to numerically investigate the performance of axially loaded, circular CFDST short columns, with the innovative strengthening technique of providing stiffeners in outer tubes. Circular steel hollow sections have been adopted for inner as well as outer tubes, while varying the length of rectangular steel stiffeners, fixed inside the outer tubes only, to check the effect of stiffeners in partially and full-length stiffened CFDST columns.

The behaviour of these CFDST columns is investigated numerically by using a verified finite element analysis (FEA) model from the ABAQUS. The behaviour of 20-unstiffened, 80-partially stiffened and 20-full-length stiffened CFDST columns is studied, while varying the strength of steel (f_yo = 250–750 MPa) and concrete (30–90 MPa).

The FEA results are verified by comparing them with the previous test results. FEA study has exhibited that, there is a 7%–25% and 39%–49% increase in peak-loads in partially stiffened and full-length stiffened CFDST columns, respectively, compared to unstiffened CFDST columns.

Enhanced strength has been observed in partially stiffened and full-length stiffened CFDST columns as compared to unstiffened CFDST columns. Also, a significant effect of strength of concrete has not been observed as compared to the strength of steel.

This study analyses the socioeconomic impact of COVID-19 on government accountability regarding the employment of both national and migrant workforces by bringing evidence from an emerging market. In doing so, this study addresses if/how the government discharged its accountability to the public during this recent global health crisis, which started in late 2019, with its effects still being felt today.

This study is based on a close reading of the relevant news media (local and international), published research and official reports, as well as ten conversations with business managers to analyse the socioeconomic impact of COVID-19 on government accountability in the Kingdom of Saudi Arabia (KSA). This study draws on insights from public choice theory in trying to understand why some governments take an economic perspective while exercising accountability to their population during the pandemic.

It was found that COVID-19 led the government to pursue plans for the localization of the professions and increase employment rates among nationals vs. foreigners or migrant workers. The crisis was exploited by the government to achieve macro socio-political and economic goals, demonstrating its accountability to citizens, rather than foreign workers. This shift shows that difficult and exceptional circumstances can present opportunities for policymakers in emerging markets to achieve national policy and political aims.

This study enhances the author’s understanding of accountability during crises (i.e. crises-induced accountability) in emerging markets. The analyses presented enrich the crisis management literature by highlighting the implicit actions of national leaders that affect the lives and well-being of their constituents, especially vulnerable groups.

This paper explores the relationship between earnings management and firms' value through the moderating effect of the missing elements – corporate social responsibility (CSR) disclosure and state ownership in Russian companies. The main argument of the paper is that CSR disclosure can be used as a mitigating mechanism to weaken the negative relationship between earnings manipulation and market value. Additionally test whether state ownership is an important moderating factor in this relationship are conducted as state has always played an important role in the emerging Russian market.

The hypotheses are tested on panel data for 223 publicly listed Russian firms for the period 2012–2018. A number of robustness tests are used to check the obtained results for consistency. Following previous research GMM method is employed to address endogeneity concerns.

Supported by stakeholder theory, it is observed that firms that disclosed more CSR information experience a weaker negative relationship between earnings management and market value because investors and other stakeholders positively evaluate a positive CSR image. This negative effect of earnings management on market value is even weaker for state-owned companies as market participants appreciate involvement of state-owned companies in CSR activities and place greater expectations on these firms to be responsible without clear understanding whether these actions are “window dressing” for this type of companies or not.

The study results provide new insights into the relation between earnings management, firm's value, CSR disclosure and state ownership in emerging-market firms. The paper highlight the importance of considering country-specific factors, such as state ownership, while analysing the market reaction on CSR disclosure and earnings management since the institutional peculiarities may help to explain differences in the obtained results.

The purpose of this study is to examine the relationship between positive emotion, self-efficacy, job satisfaction and turnover intention in the context of resource building during the socialization process of new faculty members, particularly in the context of the coronavirus disease 2019 (COVID-19) pandemic.

The study utilizes a quantitative research design and employs purposive sampling to obtain 554 valid questionnaires. The study analyzes the relationship between positive emotion, self-efficacy, job satisfaction and turnover intention and examines the influence of strategic human resource management (SHRM) on these variables.

The results of the study reveal that SHRM positively influences positive emotion and self-efficacy, which, in turn, positively impact job satisfaction. However, positive emotion is negatively related to turnover intention.

This study contributes to the existing literature on human resource management (HRM) by examining the impact of strategic HRM on the socialization process of new faculty members. The findings of the study have significant practical implications for the implementation of HRM in research-oriented universities.

This study aims to investigate the public deficit issue by contrasting conventional and Islamic views encompassing the paradigm, technical base, orientation and consequence detailed in nine discussions, which are rarely investigated in the research. There is a predisposition that contemporary Muslim scholars discuss the public deficit as well as the private sector perspective, which is used in the conventional conception, without riba as a primary feature.

The paper develops a comparative approach that derives two perspectives from the available literature using the qualitative method under the critical thinking method. It was drawn up in detail on how the paradigm and its related budgeting process contribute to public deficits, mainly in government institutions.

The paper reveals a prominent difference in public deficit in the Islamic view from a conventional perspective. From 9 points of comparison, the analysis covers 18 discussion that differentiates between private and public area criticism seems to overlap. The foundation giving a unique perspective in Islam toward public deficit is the concept of ownership that differs from capitalism, mainly the function of public spending is to distribute the wealth among people not for economic growth. The Islamic Government spent for public purposes based on cash-basis budgeting. The budgeting system in Islamic public spending is founded on treasure availability.

The paper uses a qualitative method that cannot empirically snapshot the actual or factual condition, in which subjectivity plays a plausible role. Furthermore, there is no actual sample (best practices) of the concept to be examined.

The research encompasses overlap between Islamic and conventional perspectives, including public and private issues regarding public deficits. The main beneficiary of the paper is a policymaker, including academicians or practitioners who are appropriate to use the concept in their circumstances.

The study is a pioneering study in public deficit comprehensively comparing conventional and Islamic perspectives and drawing up conceptual and technical aspects.

COVID-19 pandemic interrupted global supply chains (SCs) affecting both developed and developing countries. In context of the COVID-19 pandemic, numerous studies were conducted on sustainable supply chain (SSC) in emerging markets (EMs). However, the contributions of these studies require to be systematically reviewed to provide a platform of knowledge. The purpose of this review is to systematically explore the relevant literature on SSC management during the COVID-19 pandemic in EMs.

The authors applied Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework to perform a systematic literature review. Scopus database was used to extract the relevant literature, and 51 journal articles along with 5 conference proceedings were included in the study.

This study identified the major contents along with four different themes, which are the impacts of COVID-19 on the SC, recovery strategies to alleviate the adverse impacts of COVID-19, sustainable practices to improve SC performance and resilience activities to assure firms' survivability. Furthermore, the research reveals that interview/survey/case study–based research and review articles focusing on various industries have dominated the field of SSC management in the context of EMs.

This research enriches the literature by providing an overall scenario of SSC during the COVID-19 pandemic in the context of emerging economies.

The paper aims to the preparation of novel disperse dye based on azo salicylaldehyde derivatives TF-A [2-hydroxy-5-((3-(trifluoromethyl)phenyl)diazenyl)benzaldehyde] and full evaluation of their use as disperse dye TF-ASC [bis 2-hydroxy-5-((3-(trifluoromethyl)phenyl)diazenyl)benzaldehyde Schiff base with 4,4'-methylenedianiline] for dyeing polyester fabric at various conditions.

The dispersed dye was synthesized via Schiff base condensation in the presence of ceric ammonium nitrate cerium ammonium nitrate 10 mmole% as an eco-friendly catalyst at room temperature. The chemical structure of the prepared dye was characterized via elemental analysis, Fourier-transform infrared spectroscopy, 1H- and 13 C-NMR spectroscopic analysis tools. This study thoroughly examined the dyeing of disperse dye TF-ASC on polyester at various conditions. The characteristics of dyed polyester fabric were measured by colour measurements, as well as light, washing, crock fastness and finally, colour strength. The discrete fourier transform (DFT) theoretical studies, including E_HOMO, E_LUMO and optimized geometrical structure, were assumed and discussed in detail.

The results showed that the synthesized organic dye TF-ASC was highly functional and appropriate for this kind of dyeing method. The dyeing fabrics obtained from disperse dye TF-ASC, properties possess high colour strength as well as good overall fastness properties. These dyes had a high affinity for polyester fabric, with just a tiny change in dye affinity when the pH was changed, even under alkaline circumstances. The dye levelness and shade depth of the colour results were good, and there were a variety of hues from light brownish yellow to deep brownish yellow. The results obtained from DFT computational studies such as E_HOMO, E_LUMO, optimized structure, diploe moment µ and electrophilicity index deduced that prepared organic dye TF-ASC is more applicable as a dispersed dye.

This research is significant because it provides a new dye for dyeing polyethylene terephthalate fibres with exceptional brightness and levelness; the method of preparation is a useful pathway due to its being known as a green chemistry method.

The purpose of this paper is to investigate risk propagation and resilience in the agribusiness supply chain (ASC).

The paper undertakes a systematic literature review (SLR). Overall, 94 articles from six databases published between 2000 and 2022 underwent descriptive and thematic analysis.

There is a lack of research on risk propagation and resilience in the ASC for more than two decades. Accordingly, this research fills the gap in the extant literature by advancing the construct of risk propagation and resilience in the ASC and developing a framework proposing directions in risk propagation and resilience in ASC research.

Firstly, only the Web of Science and Scopus databases were mostly used as primary sources while other databases were used as secondary sources to validate search results. Secondly, SLR is based on the peer-reviewed articles, books and conference papers; other non-academic sources relevant to the topic were not included in this paper.

The paper offers a set of constructs for understanding risk propagation and resilience in the ASC, develops a framework proposing directions in risk propagation and resilience in the ASC research and recommends three key themes for future research directions, namely, keep updated with recent constructs of risk propagation and resilience in the ASC, conduct case studies based on empirical studies to determine the current risk dependency and propagation in the ASC and conduct case studies based on empirical studies to determine resilience and sustainability in the ASC.

This paper aims to examine the impact of board gender diversity (BOGD) following the adoption of gender quota legislation on earnings management (EM) in an emerging market, Egypt, whose cultural and economic conditions and institutional context are unlike most previously studied countries’ context.

The authors use ordinary least squares (OLS) regression to estimate the impact of gender quota legislation on EM using data from listed companies in Egypt from 2015 to 2022. Difference-in-difference (DID) approach estimation was used to validate the robustness of the main results.

This paper documents that gender diversity on boards has a significantly negative impact on EM. In addition, this paper provides robust evidence using the DID approach to show that BOGD is significantly negatively linked with EM for the period following gender quota legislation. Furthermore, the results support the critical mass and agency theories.

The findings of this study have important implications for Egyptian companies, regulatory bodies and investors in emerging markets. Specifically, these results suggest that when choosing board members, enterprises should pay particular attention to BOGD, and female involvement in all listed firms should be monitored by regulators.

This paper provides evidence supporting the positive contribution of women in society by enhancing the economic performance of Egyptian firms and promoting the country’s sustainable development strategy in light of Egypt vision 2030.

As per the authors' knowledge, this empirical study is unique in investigating the impact of BOGD quota regulation on EM in Egypt. This paper contributes to BOGD as a major factor in improving financial reporting quality in Egyptian companies.
