Knowing financial and economic information beforehand benefits in planning and developing policies for every country especially for a developing country like Thailand and for other Asian countries. Unfortunately, missing data or non-response plays an essential role in many areas of studies including finance and economics. Eradication of missing data in a proper way before further analysis can gain remarkable outcomes and can be effective for planning policies. This review on the generalized regression estimators for population total can be applied to financial, economic and other data when missing data are present.

The generalized regression estimators for estimating population total, including the variance estimators under unequal probability sampling without replacement with missing data are explored under the reverse framework. Applications to financial and economic data in Thailand are also reviewed.

The review of literatures related to the proposed estimator shows the best performance, giving smaller variances in all scenarios.

The generalized regression estimators can assist in estimating financial and economic data that contain missing values with different missing mechanisms and can be used in other applications which help gain more superior estimators.

This research paper aims to analyze the scientific and grey literature on Quality 4.0 and zero-defect manufacturing (ZDM) frameworks to develop an integrated quality 4.0 framework (IQ4.0F) for quality improvement (QI) based on Six Sigma and machine learning (ML) techniques towards ZDM. The IQ4.0F aims to contribute to the advancement of defect prediction approaches in diverse manufacturing processes. Furthermore, the work enables a comprehensive analysis of process variables influencing product quality with emphasis on the use of supervised and unsupervised ML techniques in Six Sigma’s DMAIC (Define, Measure, Analyze, Improve and Control) cycle stage of “Analyze.”

The research methodology employed a systematic literature review (SLR) based on PRISMA guidelines to develop the integrated framework, followed by a real industrial case study set in the automotive industry to fulfill the objectives of verifying and validating the proposed IQ4.0F with primary data.

This research work demonstrates the value of a “stepwise framework” to facilitate a shift from conventional quality management systems (QMSs) to QMSs 4.0. It uses the IDEF0 modeling methodology and Six Sigma’s DMAIC cycle to structure the steps to be followed to adopt the Quality 4.0 paradigm for QI. It also proves the worth of integrating Six Sigma and ML techniques into the “Analyze” stage of the DMAIC cycle for improving defect prediction in manufacturing processes and supporting problem-solving activities for quality managers.

This research paper introduces a first-of-its-kind Quality 4.0 framework – the IQ4.0F. Each step of the IQ4.0F was verified and validated in an original industrial case study set in the automotive industry. It is the first Quality 4.0 framework, according to the SLR conducted, to utilize the principal component analysis technique as a substitute for “Screening Design” in the Design of Experiments phase and K-means clustering technique for multivariable analysis, identifying process parameters that significantly impact product quality. The proposed IQ4.0F not only empowers decision-makers with the knowledge to launch a Quality 4.0 initiative but also provides quality managers with a systematic problem-solving methodology for quality improvement.

Funding difficulties are particularly compounded for Muslim entrepreneurs in Nigeria, owing to the dominance of interest-based financial institutions prohibited in Islam. Thus, this study aims to explore the role of awareness of Islamic finance principles in ameliorating financial deprivation and financial anxiety to increase access to Islamic financing among Muslim entrepreneurs.

A quantitative survey method of data collection was used to collect data from a total of 208 micro, small and medium enterprises (MSME) owners based on hand-delivered questionnaires. The data was analyzed using a partial least square structural equation model.

The result supports the direct negative impact of relative financial deprivation and the positive impact of awareness of Islamic finance principles on access to Islamic finance. However, awareness of Islamic finance principles could not moderate any of the direct relationship.

This study implies that financial deprivation is detrimental to access to Islamic finance, but financial anxiety has no significant impact. In addition, policymakers and MSME owners could directly foster access to Islamic finance through awareness of Islamic finance principles, though it could not redirect the negative impact of relative financial deprivation on access to Islamic finance.

The valuable finding here is that the substantial positive impact of awareness of Islamic finance principles on access to Islamic finance is not enough to redirect the negative effect of relative financial deprivation on access to Islamic finance.

Social network group decision-making (SNGDM) has rapidly developed because of the impact of social relationships on decision-making behavior. However, not only do social relationships affect decision-making behavior, but decision-making behavior also affects social relationships. Such complicated interactions are rarely considered in current research. To bridge this gap, this study proposes an SNGDM model that considers the interaction between social trust relationships and opinion evolution.

First, the trust propagation and aggregation operators are improved to obtain a complete social trust relationship among decision-makers (DMs). Second, the evolution of preference information under the influence of trust relationships is measured, and the development of trust relationships during consensus interactions is predicted. Finally, the iteration of consensus interactions is simulated using an opinion dynamics model. A case study is used to verify the feasibility of the proposed model.

The proposed model can predict consensus achievement based on a group’s initial trust relationship and preference information and effectively captures the dynamic characteristics of opinion evolution in social networks.

This study proposes an SNGDM model that considers the interaction of trust and opinion. The proposed model improves trust propagation and aggregation operators, determines improved preference information based on the existing trust relationships and predicts the evolution of trust relationships in the consensus process. The dynamic interaction between the two accelerates DMs to reach a consensus.

The interest in older entrepreneurs increases due to population aging. Previous research showed clear gender-differences among older entrepreneurs. This study investigates whether such gender-differences also exist in the retirement transition from entrepreneurship. It explores the influence of pension regulations for entrepreneurs on these gender-differences.

Longitudinal micro-level data from the Survey of Health, Aging and Retirement in Europe is analyzed in multichannel sequence analyses and cluster analyses. Developments from age 50 to 69 are compared in the dimensions of entrepreneurship, employment and old-age pensions.

Entrepreneurs retire in three different transition patterns: (1) entrepreneurs becoming pensioners at 60, (2) entrepreneurs becoming pensioners at 65 and (3) individuals combining entrepreneurship with employment until they become pensioners at 65. Female entrepreneurs follow the same transition patterns as their male counterparts but retire earlier. Pension regulations for entrepreneurs modify the extent of the gender-differences within a country. Mandatory pension schemes with identical state pension ages for men and women reduce gender-differences, whereas mandatory schemes with gender-differences in the state pension age increase them. Schemes without mandatory coverage range in between the other two.

This article expands our knowledge on gender-differences among older entrepreneurs. These gender-differences also extent to how entrepreneurs transition into retirement. Pension regulations for entrepreneurs influence the extent of the gender-differences. Therefore, pension regulations for entrepreneurs constitute tools for promoting or hindering gender equality.

This study aims to identify the librarians’ readiness to leverage artificial intelligence for sustainable competence development and smart library services.

This study used a quantitative research design for addressing the objectives. The population consisted of librarians from the public and private sector universities of Pakistan. The data were analyzed by using Smart PLS software.

The analysis consisted of two major parts: first the assessment of measurement model and second the structural equation modeling analysis. A significant positive impact of AI adoption was found on the implementation smart library services. Findings revealed that behavioral intention motivated librarians to adopt AI tools in university libraries for the delivery of smart library services.

We applied quantitative method to carry out the study while future authors may conduct a systematic literature review on the same topic for offering a broader outlook.

It has provided practical contributions by providing a baseline for management bodies to construct policies for the successful adoption of AI in libraries for sustainable competence development of practicing librarians and implementation of smart library services.

The study has social implications too as AI integrated library services prove fruitful for society and digitally skilled librarians play a vital role for the promotion of reading and research culture in society.

To the best of the authors’ knowledge, this is the first study on librarians’ readiness to leverage artificial intelligence for the enhancement of digital literacy skills, sustainable competence development and smart library services in the context of Pakistan.

This study examines the relationship between internal control and corporate environmental responsibility.

Unlike US studies that concentrate solely on internal control over financial reporting, this study uses a comprehensive index that encompasses internal control over financial reporting, operations, and compliance. Corporate environmental responsibility is measured by environmental investments. Our research sample comprises Chinese listed firms from 2010 to 2018.

The results demonstrate a positive correlation between internal control and corporate environmental investments. Furthermore, we find that firms with high-quality internal control can improve their financial and environmental performance through environmental investments. After decomposing internal control into its five components, we show that the control environment, control activities, and information and communication components exhibit stronger effects on environmental investments than the risk assessment and monitoring components. Finally, the cross-sectional analyses reveal that the positive effect of internal control is more pronounced in private firms and in firms that are subject to weaker environmental regulation.

By focusing on the effect of a comprehensive internal mechanism on corporate environmental responsibility in China, this study contributes to the literature in developed-country settings that overwhelmingly focuses on the impact of external stakeholders and regulations.

Based on the stereotype content model (SCM), this study aims to enrich comprehension of virtual service assistant (VSA)-enabled service delivery through two pivotal avenues. Firstly, it aims to conceptualize and test the fundamental mechanism underlying how businesses deploy services using VSAs. Secondly, this study explores whether the paradigms of service co-creation versus service recovery differentially impact customers’ perceptions of warmth and competence in VSA-enabled service delivery.

This study used a one-factorial (service paradigm: service co-creation vs service recovery) field experiment. Covariance-based structural equation modelling was used to analyze the data.

The results show that VSA service quality dimensions impact satisfaction for service co-creation and both trust and satisfaction for service recovery. The stronger link that mediates this effect is competence for service co-creation and warmth for service recovery.

This research extends the understanding of SCM to VSA-enabled services and shows the asymmetries of mediation between the paradigms of service co-creation versus service recovery to suggest the most effective approach for VSAs to successfully meet customer requirements for establishing trust and satisfaction.

The purpose of this paper is to propose and validate a theoretical model to investigate the relationship between self-organisation, information integration, adaptability and supply chain agility in humanitarian organisations.

A theoretical model was developed from extant studies and assessed through a structured questionnaire survey of 86 humanitarian organisations operating in South Sudan. The data were analysed using partial least square structural equation modelling.

The study found that self-organisation has a discernible positive influence on supply chain agility not only directly but also indirectly through adaptability. Further, information integration does not significantly influence supply chain agility directly but is fully mediated by adaptability. Together, the antecedent variables account for 53.9% variance in supply chain agility.

This study contributes to providing an empirical understanding of a humanitarian supply chain as a complex adaptive system and hence the need to incorporate self-organising and adaptive dimensions in supply chain management practice. Furthermore, it confirms the centrality of the complex adaptive system feature of adaptability when building supply chain agility through self-organisation and information integration.

The findings provide a firm ground for managerial decisions on investment in self-organisation and information integration dimensions so as to enhance adaptability and improve supply chain agility in humanitarian organisations.

This study is distinctive in the sense that it uses the complex adaptive system variables to empirically validate the relationships between self-organisation, information integration, adaptability and supply chain agility in humanitarian organisations in the world’s youngest developing economy with a long history of conflict and humanitarian intervention. The mediating influence of adaptability examined in this study is also novel.

Despite the online shopping trend, many women still prefer in-store experiences for trying on and buying clothes. The body positivity movement endorsed by many brands implies that all women, even those with lower body appreciation, should feel included in this setting. However, studies have yet to quantitatively explore the mediating role of women’s positive body image between clothing size and in-store experiences. To address this gap, this study examined the in-store experiences of 642 women from largely Western nations (Mage = 45.96, standard deviation (SD) = 9.31) who self-reported as straight-, mid- and plus-sizes and the mediating role of body appreciation.

Participants completed online questionnaires with measures including clothing size, body appreciation, in-store experiences and preferences for in-store changes.

Women of mid-size and plus-size were more likely than women of straight-size to report lower body appreciation, which led to a greater desire for guidance from staff about styles but less likelihood to approach them, higher discomfort going up a size and lower confidence trying on clothes. In contrast, straight-size women generally felt more comfortable and confident in-store clothes shopping. A direct link between clothing size and lower purchase intentions without in-store representation was found; however, body appreciation did not mediate this link. Preferences for in-store changes included better support from sales staff and more inclusive imagery.

This study indicates that in-store clothes shopping may not feel like retail therapy for women who identify as mid-size or plus-size and experience low body appreciation. It highlights the need for comprehensive reform within the fashion retail industry by prioritizing inclusivity through better staff support and in-store representation for all sizes.
