The purpose of this article is to investigate the variables affecting heat transfer from the surfaces of a tall building and also the extent of the impact of each of them. Another purpose of this paper is to provide a suitable model for estimating the heat transfer coefficient of the external surfaces of the building according to the impact of variables.

In this study, the Taguchi's approach in the design of the experiments was used to reduce the number of experiments. Percent contributions factors into the overall and surface-averaged Nu of a square prism were obtained by the (ANOVA). The change in Nu by changing either of T, P, angle of attack and V were investigated by the (ANOM). The most significant factors affecting the value Nu were also identified to facilitate the design of thermal systems by eliminating the factors imposing no significant effect on the response in the molding phase. The set of conditions under which the air properties remained unchanged was identified. Five correlations were formulated to predict Nu.

Models used in BES, in which the effects of T, P, A and geometrical effects are not accounted for, are not reliable. The air pressure was found to impose no significant effect on the overall Nu of the considered square prism. Studied in the range of 274–303 K, the air temperature imposed a significant effect on the overall Nu. The results of ANOVA show the significant role of Re to predict Nu of tall buildings.

This article is taken from a doctoral dissertation.

The purpose of this article is to develop a new model called strategy segmentation methodology (SSM) by combining the Kraljic portfolio matrix (KPM) and the supplier relationship model (SRM) so that the buyer company can effectively conduct its relations with its suppliers.

The importance weights of the criteria defining the dimensions of each model are calculated with the single-valued neutrosophic analytical hierarchy process (SVN-AHP) method. Subsequently, the derived importance weights are employed in the single-valued neutrosophic technique for order preference by similarity to ideal solution (SVN-TOPSIS) method to obtain the scores of the suppliers and their supplied items. In order to illustrate the feasibility of the proposed methodology, a case study in the machinery industry is performed with the related comparative analysis.

The implementation of SSM enables to formulate various strategies to manage suppliers taking into account the items they procure, their capabilities and performance and the supplier–buyer relationship strength. Based on the proposed strategies, it is concluded that the firm in the case study should terminate its relationship with six of its suppliers.

Although KPM has become the basis of purchasing strategies for various businesses, it neglects the characteristics of suppliers and the buyer–supplier relationship. In this study, KPM is integrated with the SRM approach presented by Olsen and Ellram (1997) to overcome these disadvantages of KPM. The novel integration of the two approaches enables the realization of a robust and reliable supplier classification model.

This study aims to investigate whether there are disparities in research and development (R&D) internationalization between latecomers from economy-level technological disparities and firms with ownership-specific technological capability differences in the wind turbine industry.

Employing econometric analysis based on patent indicators, the authors examine the patent data assigned by the United States Patent and Trademark Office (USPTO) to the technologically advanced economy and the technologically emerging economy.

This study finds that latecomers from technologically advanced economies behave with no difference from early leaders in terms of international co-invention (INCO) but do show differences in another indicator – native ownership of foreign inventors (NOFIs). Additionally, latecomers from economy-level technological disparity show significant differences both in both INCO and NOFI. These results indicate that the latecomers from technologically advanced economies not only possess the nature of latecomers which motivates them to seek knowledge from foreign economies but also benefit from their advanced home base, thereby prompting them to internationalize and access cost-effective R&D resources. Moreover, the results demonstrate that latecomers from technologically emerging economies are more prone to engage in R&D internationalization to augment their own home base compared with firms from advanced economy.

This study extends the literature on R&D internationalization by introducing novel perspectives. It distinguishes some apparent distinctions of the tendency of R&D internationalization between latecomers under economy-level technological disparity as well as firms from ownership-specific technological capabilities differences. Additionally, this study disaggregates R&D internationalization into twin key dimensions: INCO and NOFI. These findings allow for a comprehensive understanding of the differences in the firm's R&D internationalization under economy-level technological disparities and ownership-specific technological differences. These findings offer valuable insights for decision-makers in navigating global innovation activities by highlighting the diverse economy-level technological advantages as well as ownership-specific advantages.

The purpose of this study is to address the issue of customer engagement faced by the hospitality industry. By employing the Stimulus–Organism–Response (S-O-R) model and engagement theory, this study investigates the influence of social media marketing (SMM) and consumers' perceived innovativeness on customer engagement. Additionally, it explores the mediating role of customer satisfaction. Lastly, it examines the moderating effect of service convenience between customer satisfaction and customer engagement.

This study is quantitative in nature. Data were collected through surveys using a three-wave time-lagged design from 564 consumers of various restaurants.

The findings reveal that SMM did not directly impact customer engagement; however, it showed a full mediation through customer satisfaction. Perceived innovativeness showed a significant relationship with customer engagement both directly and indirectly. Service convenience also showed significant moderation.

The study is useful for the hospitality managers and the restaurant industry as a whole in facilitating memorable customer experiences in order engage them for longer time periods. This study would also help give other firms in the service sector a direction to better engage with their customers.

This study by investigating the unique framework produces the useful information for hospitality managers, policy makers and contributes to the body of knowledge from a developing country's perspective. Testification of S-O-R model and engagement theory are also significant theoretical contributions.

Although previous research has recognized the pivotal role of mobile social media in knowledge sharing among project members, little is known about what factors affect knowledge sharing in mobile social media groups (MSMGs). Against this background, using normative social influence theory, this study attempts to explore factors influencing knowledge sharing in MSMGs.

Data from 205 Chinese construction project members are collected and used for analysis. Ordinary least squares regression by Stata 16 is used to test the proposed hypotheses.

Concerning role norms, gender difference in knowledge sharing behavior (KSB) is found, while it is not the case for knowledge quality (KQ). Work experience is found to positively affect KQ, but shows no influence on KSB. As for group norms, the inverted-U relationship between number of members and KSB is partially supported. In addition, organizational norms generally exhibit the greatest influence on both KSB and KQ among the three forms of norms.

This study deepens the understanding of knowledge sharing factors in mobile social media environments and affords practical implications for how to make full use of social media for knowledge management within construction project teams.

This study aims to examine whether information asymmetry (IA) mediates the relationship between women directors and the cost of equity (COE). Specifically, this study posits that women directors tend to lower the COE through the channel of IA.

This study uses the US-listed firms’ data from 2002 to 2014, comprising 11,189 firm-year observations. This study measures the COE by aggregating the four unique market-based COE models and apply pooled ordinary least square to estimate our results.

This study documents that women directors are linked to IA, and that IA is linked to the COE. Furthermore, in the mediation test, IA fully mediates the relationship between women directors and the COE. This study's results also validate the critical mass hypothesis, as the IA shows full mediation between the critical mass of women directors and COE. This study also discusses the limitations and major implications of the results along with possible future directions.

This study also supports the positive role of females in improvising the economic performance of the firms and supporting the sustainable development goals-5 (gender equality).

The originality of this study lies in its theoretical as well as empirical contributions. First, this study follows the line of inquiry of the mediation analysis, thereby contributing by examining whether the relationship between women directors and financial value, i.e. COE, is indirect. Second, in addition to ex post measures of the COE, this study used four ex ante unique market-based models to measure the COE. Most of the prior studies just rely on book-based measures or use a single market-based mode. Third, the findings contribute insights into how women directors add value and benefits firms.

This study aims to investigate the relationship between financial inclusion and risk-taking by Chinese banks.

It uses the panel data from Chinese banks ranging from 2011 to 2019 and applies system generalized method of moments to measure coefficients. To get in-depth understanding of the relationship between above-mentioned variables, the analysis for commercial, cooperative, listed, unlisted, small and large banks has been done. Financial inclusion index has been measured based on demographic and geographic aspects by using the principal component analysis, and bank risk-taking has been proxied by z-score.

The findings reveal an inverse relationship between financial inclusion and bank risk-taking which implies that an increase in financial inclusion results in lesser risk for the banks, i.e. diversification hypothesis applies. However, the results for unlisted and large banks show a different story where an increase in financial inclusion results in higher bank risk and vice versa.

The present study offers several valid and convincing implications for consumers, policymakers and banking sector regulators.

This study aims to analyse the role of the financial and accounting expertise of the chief executive officer (CEO) on financial reporting quality (FRQ) in an emerging economy.

This study is based on data collected from a large sample of all non-financial companies listed on Vietnamese stock exchanges during the period 2016–2020 with 2,435 observations. FEM-ROBUST standard errors regression model is used to examine the relationship between the financial, accounting expertise of CEOs and FRQ through earnings management by discretionary accruals.

The results show that CEOs with financial and accounting expertise have more influence and intervention on earnings management and thus adversely affect FRQ. This behaviour is explained by the fact that CEOs not only have a firm grasp of financial and accounting policies but also know the tricks to interfere with earnings management. Moreover, in the context of emerging economies, CEOs’ awareness and management level are still limited and legal sanctions are not yet strict, so when they have power in their hands, CEOs immediately find ways to build a reputation to enhance the power and earnings for the CEOs themselves.

The limitation of this study is first of all that the research data are not complete and rich because the companies are prohibited from disclosing information and the cooperation relationship is not close. Next is the new research in only one emerging market – Vietnam – so the generalizability is not high.

To the best of the authors’ knowledge, this is the first study to examine the impact of CEOs’ accounting and finance expertise on FRQ in an emerging economy, contributing to the existing literature regarding the scientific debates about CEOs, CEO characteristics, earnings management and FRQ.

This study aims to examine the relationship between employees’ psychological contract breach and two types of voice behavior based on the social exchange theory. Additionally, the study explores the role of globally responsible business leadership in buffering the negative impacts of psychological contract breach on voice.

Survey data was collected from Chinese full-time employees and the final sample size is 337. Partial least squares structural equation modeling was used to test the hypotheses.

Findings indicate that psychological contract breach (PCB) has a positive and significant impact on employee aggressive voice behavior (AVB), while its relationship with constructive voice behavior (CVB) is not significant. Furthermore, globally responsible business leadership (GRBL) weakens the negative relationship between PCB and CVB, while strengthens the positive relationship between PCB and AVB.

The findings assist organizations in better recognizing the detrimental consequences of psychological contract breach. Second, the findings serve as a reminder to managers of the benefits of displaying globally responsible business leadership. Third, managers should recognize the complexities of globally responsible business leadership.

First, this study sheds new light on the impact of PCB on employees’ desirable and undesirable proactive behaviors by investigating how and when psychological contract breach affects two types of voice behavior. Second, the moderating role of GRBL further enriches our understanding of how to buffer negative effects of PCB and the desirable function of GRBL. Third, this study enriches the social exchange theory by investigating whether the leader−employee relationship will compensate for the failure of organization−employee relationship.

Family farms, in which business and family life are intricately interwoven, offer an interesting context for better understanding the interdependence between the family and business system. Many family farms struggle to survive, and the succession process is a key period in which the low returns on investment become evident but also the emotional attachment of the family to the farm and the willingness to transfer the business to the next generation. We take the perspective of non-succeeding siblings since they are crucial for a successful succession but their role and position in this process is far from clear. This study will help to increase our knowledge of how fairness is perceived by non-successors and of the impact of perceived (in)justice on the family business system.

To analyze the effect on sibling relationships of an unequal outcome of the succession process, we choose the family farm context. We used interview data from multiple family members from several family farms in the Netherlands in different stages of succession. We utilized a framework based on justice theory to analyze perceptions of fairness among non-succeeding siblings. The central research question for this study is as follows: How do non-succeeding siblings perceive justice with regard to family firm succession?

The acceptance of the outcomes of the succession process by non-succeeding siblings is influenced by their perception of the fairness of the process itself and decisions made by the incumbent and successor with regard to these outcomes. It seems that stakeholders who occupy multiple roles with conflicting justice perspectives handle these contradictions with the help of an overarching goal—in this study, preserving the continuity of the family farm—and by prioritizing and adjusting the justice perspectives accordingly. The findings further show that both distributive justice and procedural justice are important and interact with each other.

Our study contributes to the literature by applying the theoretical framework of distributive and procedural justice to the context of family farm succession. This helps us to understand the position of non-succeeding siblings and their role and position in the succession process, which is important because sibling relationships have a significant impact on family harmony, with potential consequences for the business as well.
