Abstract

Purpose

To address the effects of velocity profile at the discharge air grille (DAG) on the amount of entrained air into an open refrigerated display case (ORDC).

Design/methodology/approach

The performance of an ORDC was studied by CFD, DPIV and LDV. The actual measured velocity profile at the DAG and total flow rate of the display case at its nominal operating conditions are used as guidelines throughout the CFD modeling.

Findings

It was found that a skewed parabolic profile with the peak shifted towards the inner section of the case generates the minimum entrainment and demonstrates that with simple changes to the geometry of the DAG, a significant reduction in the entrainment rate could be achieved.

Research limitations/implications

This study finds the optimum infiltration rate of a manufactured ORDC. A fundamental study is currently being done to address all the effective parameters that can affect the infiltration rate of any ORDCs.

Originality/value

This paper presents this fact that the velocity profile at the DAG has a significant impact on the infiltration rate and electricity consumption of ORDCs. In turn, the velocity profile is dependent on the geometry and shape of the air passage before DAG. Thus, the analysis of the effect of the geometry on the velocity should seriously be taken into consideration by the case manufacturers.

Abstract

Purpose

The purpose of this paper is to develop a general numerical solution for the wetting fluid spread into porous media that can be used in solving of droplet spread into soils, printing applications, fuel cells, composite processing.

Design/methodology/approach

A discrete capillary network model based on micro‐force balance is numerically implemented and the flow for an arbitrary capillary number can be solved. At the fluid interface, the boundary condition that accounts for the capillary pressure jump is used.

Findings

The wetting fluid spread into porous medium starts as a single‐phase flow, and after some particular number of the porous medium characteristic length scales, the multi‐phase flow pattern occurs. Hence, in the principal flow direction, the phase content (saturation) decreases, and in the lower limit for the capillary number sufficiently small, the saturation should become constant. This qualitative saturation behavior is observed irrespective of the flow dimensionality, whereas the quantitative results vary for different flow systems.

Research limitations/implications

The numerical solution has to be expanded to solve the spread of the fluid in the porous medium after there is no free fluid left at the porous medium surface.

Practical implications

It is shown that the multi‐phase flow can develop even on a small domain due to the porous medium heterogeneity. Neglecting the medium heterogeneity and flow type can lead to a large error as shown for the droplet spread time in the porous medium.

Originality/value

This is believe to be the only paper relating to solving the droplet spread into porous medium as a multi‐phase flow problem.

Abstract

Purpose

The purpose of this paper is to examine the relationship between consumers' satisfaction with their health insurance and quality of life (QoL), the mediating role of perceived financial burden in this relationship, as well as the moderating effect of external locus of control (LoC) on the relationship between perceived financial burden and QoL among cancer patients.

Design/methodology/approach

A cross-sectional design was employed in order to collect quantitative data by means of a self-administrated questionnaire. Participants consisted of 387 conveniently selected consumers diagnosed with cancer in Iran. Furthermore, the questionnaire was translated into Persian using a forward–backward method. The model was tested using partial least squares structural equation modeling (PLS-SEM).

Findings

The results indicate that the more satisfied patients are with their health insurance, the higher QoL they experience, and this relationship is explained through reducing perceived financial burden in terms of direct and indirect costs of the disease. Although external LoC belief is negatively related to QoL, it buffers the negative association between financial burden and QoL.

Practical implications

Reducing the disparity between consumers' expectation and perception of the comprehensiveness of health insurance policies may relieve consumers' anxiety stemming from financial worries.

Originality/value

This paper fills a gap in the literature where consumers' perception about quality of insurance and its relationship with their QoL has received little attention so far.

Abstract

Purpose

This study seeks to add more insights to the debate on “whether”, “how”, and “under which condition” women representation on the board contributes to firm performance. More specifically, the current study aims to investigate if the effect of board gender diversity on firm performance is dependent on macro factors of national cultures.

Design/methodology/approach

The authors used the generalized method of moments regression and a data set consists of 2,550 company year observations over 10 years.

Findings

The results indicated that cultural variables interact with board diversity to influence firm performance. Having women on the board in countries with high power distance, individualist, masculine and low-uncertainty avoidance culture influences the firm performance negatively.

Originality/value

The findings indicate that the effects of corporate governance structure on firm performance depends on culture-specific factors, providing support for the argument that institutional norms that are governed by cultural norms affect the effectiveness of corporate governance structure.

Abstract

Purpose

The purpose of this paper is to investigate whether financial distress explains the relationship between financial literacy and quality of life (QoL) among consumers who have faced life-threatening cancer. To extend this line of research, the moderating role of social supports in the relationship between financial distress and QoL is examined.

Design/methodology/approach

A cross-sectional survey was utilized to collect quantitative data through a self-administered questionnaire. A total of 223 consumers diagnosed with cancer in Iran participated in the study by means of a convenience sampling technique. Using a forward–backward method the questionnaire was translated from English into Persian.

Findings

The findings highlight the importance of financial literacy in managing direct and indirect costs of chronic diseases that in turn can improve consumers' QoL. Moreover, while perceived social support improves QoL of consumers diagnosed with cancer, it strengthens the negative association between financial distress and QoL. Consequently, solely receiving of emotional support from acquaintances with no financial support might be bothersome.

Practical implications

The findings highlight the need for interventions that target financial literacy and perceived financial distress for consumers with chronic diseases. These consumers can benefit from interventions that offer support based on accurate assessments of their needs and priorities.

Originality/value

The present study is the first of its kind to highlight the importance of financial literacy in improving the QoL of consumers with chronic diseases.

Abstract

Purpose

This study aims to investigate whether gender predicts financial inclusion and whether education can fill the gender gap in financial inclusion when controlling for the effects of supply side factors of financial inclusion in low-income economies.

Design/methodology/approach

This study aims to investigate whether gender predicts financial inclusion and whether education can fill the gender gap in financial inclusion when controlling for the effects of supply side factors of financial inclusion in low-income economies.

Findings

The findings provided support for the gender gap in financial inclusion using the most basic measure of financial inclusion. However, using formal savings and access to credit, the gender gap hypothesis is not supported. Moreover, the results revealed that education reduces the gender gap in the basic form of financial inclusion. However, this study could not find any significant difference between men and women's financial inclusion in terms of saving at a bank or borrowing from a bank though men tend to save more than women informally.

Originality/value

The current study contributes to the literature by examining the role of education in the relationship between gender gap and financial inclusion when controlling for the effects of heterogeneous infrastructure and the supply side factors of financial inclusion among the selected countries.

Abstract

Purpose

This study examined the relationship between financial information seeking behavior and financial literacy, as well as the relationship between parents' teaching and behavior with financial information seeking behavior through the factors of the risk information seeking and processing model among youth.

Design/methodology/approach

A sample of 802 tertiary education students participated in this cross-sectional study. Using covariance-based structural equation modeling, the model was assessed and hypotheses were tested.

Findings

The results revealed that financial information seeking behavior contributed to youth's financial literacy. While parents' sound financial behavior was directly related to seeking financial information, both parents' financial teaching and behavior indirectly, through the risk information seeking process, encouraged youth to actively seek for financial information. Moreover, parents' financial socialization directly and also indirectly through the risk information seeking and processing model explained youth's financial information avoidance. Among the two parts of the risk information seeking and processing model, planned behavior factors played a more salient role than cognitive need for financial information.

Originality/value

This study extends the risk information seeking and processing model by integrating family financial socialization to the model and applies it in the context of consumers' financial behavior. The results improve our understanding of the social and psychological mechanism that drives consumers' financial literacy and decision-making.

Abstract

Purpose

By taking the theory of entrepreneurial legacy as the baseline, this study explores the various aspects of succession planning in indigenous family businesses especially the role of female family members in succession and conflicts in family businesses.

Design/methodology/approach

The study is qualitative in nature and adopts narrative inquiry to explore the aspects of succession planning. In doing so, the study utilizes an in-depth interviewing technique with nine participants who run their family-owned firms which are mostly in their second or third generation for analysis.

Findings

The findings are concurrent with the literature that indicates a lack of strategic succession planning although ordinary or natural succession does occur in some firms. The study also reports a lack of consideration for female members in succession, daughters in particular, for traditional family firms (FFs) in contrast to entrepreneurial FFs.

Research limitations/implications

The study has many implications for family-owned firms in Pakistan as they need to align their family business with the theory of entrepreneurial legacy and its three strategic activities in order to ensure the longevity of their business.

Originality/value

Exploring how succession planning takes place in family indigenous family businesses and what is the role of female family members in succession and conflicts in family businesses are original contributions of this study.

Abstract

Purpose

This study examines the outsourcing criteria prevalent in the Hotel industry of Pakistan. In doing so, the study investigates the role of trust in the association between relationship marketing dimensions—communication, opportunistic behavior, reputation, satisfactory prior outcomes and specific investment—and third-party logistics provider’s (3PL) selection.

Design/methodology/approach

Using a close-ended questionnaire, data were collected from 97 hotels of various categories operating in Pakistan and involved in 3PL outsourcing. Partial Least Square–Structural Equation Modeling was employed to estimate the modeled relationships.

Findings

With a high predictive relevance of the model, communication, satisfactory prior outcome and reputation were found to have a significant effect on the trust, whereas the results showed a significant mediating role of trust in the association between communication, reputation and 3PL provider’s selection.

Research limitations/implications

The study uses static data from selected firms and cannot be used to analyze behavior over a period of time. Hence, a generalization of results should be made carefully.

Practical implications

Findings imply that for fully capitalizing on the benefits by virtue of their prospective relationship, the managers must streamline their processes and activities according to path directions that endorse a higher degree of trust in their service providers and establish an effective system of communications interconnecting their mutual goals and objectives.

Originality/value

The outcome of the research study illustrated the perceptions of the local businesses with regards to the 3PL service provider(s) selection via the establishment of trust.
