Abstract

Purpose

This study investigates a production process that requires N kinds of components for the production of a finished product. The producer orders the various kinds of components from different suppliers and receives the orders in lots at the beginning of each production cycle. Similar to situations often encountered in real life, the lead times are random variables with known probability distributions so that a production cycle starts whenever all N kinds of components become available. Each of the lots received at the start of a production run contains both perfect and imperfect quality components. Once all N kinds of components become available, the producer initiates a screening process to detect the imperfect components. The production of the finished product uses only perfect quality components. The imperfect components are removed from inventory whenever the screening process is completed. The percentage of components of perfect quality present in each lot is a random variable with a known probability distribution.

Design/methodology/approach

This production process is described and modeled mathematically and the optimal production/ordering policy is derived based on the mathematical model.

Findings

The formulated mathematical model resulted in the determination of the optimal policy consisting of the optimal number of finished items ordered to be produce during each production run, the number of components ordered from each supplier, and the reorder point. The derived closed form expression for the optimal lot size depends on the minimum of the number of perfect quality components in a lot, whereas the reorder point is determined based on the maximum lead time.

Practical implications

The modeling approach and results of this study provide practical implications that may be beneficial to both production and supply chain managers as well as researchers.

Originality/value

This modeling approach that incorporates decision-making related to the logistics of acquiring the components and accounts for the probabilistic nature of the lead times and quality of components addresses a gap in the logistics/production literature.

Abstract

Purpose

The purpose of this paper is to address the following issues: first, the significance of the three independent variables (the chassis, trim, and assembly departments) on the three outputs (direct run loss first time capability, jobs per hour (JPH) lost, and injury rate); second, the optimal level of span of control based on the best achieved outputs; and third, whether increasing the span of control post 2009 improved manufacturing outputs in comparison with a span of control pre 2009.

Design/methodology/approach

The optimal level of span of control at the automotive Big Three (Chrysler LLC, Ford, General Motors) is investigated using design of experiments.

Findings

The analysis shows that the variables are significant for all outputs, except for chassis on injury. All three variables deteriorate as the span of control increases. The paper indicates that the lower the span of control the better the output variables.

Originality/value

Based on the recommendations given by the managers at the Big Three facilities visited, the top three variables that were utilized from the assembly facilities for this study are the span of control at the Chassis, Trim, and Assembly departments, and the outputs are Direct Run Loss First Time Capability, JPH Lost, and Injury Rate.

Abstract

Purpose

The purpose of this paper is to highlight the value of university social responsibility (USR) by investigating its impact on student–university identification and student loyalty. It also examines the mediating effect of student–university identification and the moderating effect of the perceived importance of USR. A comparative study is also conducted between students from two diverse cultural backgrounds.

Design/methodology/approach

An online questionnaire was administered to students of universities in two different emerging markets economies (Lebanon and Colombia). The collected data were tested by applying descriptive techniques, cluster analysis and partial least square structural equation modeling with multi-group analysis using SmartPLS3.0 software.

Findings

The findings revealed that USR affects student loyalty both directly and indirectly through student–university identification.

Research limitations/implications

Assessing the model through a more varied sample population from different cultural backgrounds would entail more universal results and the ability to generalize the causality relationship between USR and student identification and loyalty.

Originality/value

This study is a valuable addition to the scarce literature on USR and its interplay with student–university identification. It presents USR as a vital marketing tool to achieve student identification and loyalty, being key factors that impact student enrollment and retention. It also translates into a competitive advantage for higher education institutions to overcome the fierce competition in the educational market. Additionally, this research can be considered a laboratory for theory testing and theory building due to its unique context and original primary data.

Abstract

Purpose

Studies show that corporate governance (CG) and corporate social responsibility (CSR) are driven by ethical practices. The relationships between corporate ethics, CG and CSR have been heavily studied indicating significant associations. The purpose of this paper is to examine the mediating role of CG on the relationship between ethics and CSR.

Design/methodology/approach

Data were collected through questionnaires from small to medium-sized enterprises (SMEs) in the Middle East and North Africa (MENA) countries. The results were analyzed using structural equation modeling.

Findings

The results indicate that ethical practices have positive impact on CG, and in turn CG has a positive impact on CSR. The results also reveal a mediating effect of CG on the relationship between ethics and CSR.

Research limitations/implications

The sample selected is based on two countries in the MENA region, Egypt and Lebanon. Only SMEs are considered.

Practical implications

The innovative capabilities of SMEs in developing and emerging economies could be enhanced through corporate ethical practices which guide management for more CSR engagement through good CG.

Originality/value

The study contributes to corporate ethics, CG and CSR literature by providing evidence from a significant region, with both developing and emerging economies, on the mediating role of CG on the relationship between ethics and CSR.

Abstract

Purpose

With over 3,000 academic journals in the fields of Business and Economics, most academics face a hard time selecting an adequate journal to submit their work to. In today's demanding academic environment and with the presence of different journal ranking lists (JRLs), the selection becomes more difficult when considering employment, promotion and funding. The purpose of this paper is to explore key differences among multiple JRLs pertinent to the latter common objectives. An extensive analysis is conducted to compare the content of journals in the Australian Business Deans Council (ABDC) Journal Quality list, Scopus and Web of Science (WoS) in the fields of Business and Economics. Then, a case of a university with medium research output is considered where scholarly performance evaluation is based on the ABDC Journal Quality List.

Design/methodology/approach

After ranking journals in the fields of Business and Economics based on SCImago Journal Rank (SJR) indicator, JCR's Journal Impact Factor (JIF) and JCR's Eigenfactor (EF), a methodology is proposed to categorize journals in the three JRLs into the same categorization adopted by ABDC. The latter establishes a way to compare the four JRLs under consideration and serves as a basis to compare and analyze the content of journals in the ABDC Journal Quality list, Scopus and WoS. As a proxy impact metric, a normalized citation count is associated with each article based on Google Scholar. The publications of the considered university are then evaluated from the perspective of the four JRLs in terms of citation-based impact and quality while considering the exposure to popular world university ranking tables.

Findings

For journals classified under fourth tier by ABDC, over 53 and 59% are not indexed by Scopus and WoS, respectively. In this case study, over 42% of the publications appear in journals that are not listed in JCR despite the fact that over 94% of them are listed by the SJR list. Generally, publications that appear in journals listed by JCR achieve, on a yearly average, significantly higher citation rates when compared to those that appear in journals listed in ABDC and SJR Lists.

Originality/value

A four-tier mapping is proposed for consistent comparison among JRLs. Normalized citation count associated with each article based on Google Scholar is employed for evaluation. The findings provide recommendations for scholars, administrators and global universities, including Euro-Med Universities, on which JRL can be more influential for both faculty development and positioning of the university.

Abstract

Purpose

With the increasing awareness and recognition of the importance of corporate governance (CG), its practices and mechanisms along with their effect on performance and general organization’s behavior have become of interest for many scholars. The purpose of this paper is to examine the relationship between CG, with a focus on the board of directors (BOD) and the audit committee, and the level of corporate social responsibility (CSR) practices toward health, refugees, community, and environment.

Design/methodology/approach

Data were collected through a questionnaire distributed to 203 employees working at family-owned enterprises (FOE) in Lebanon. SmartPLS 3.0, statistical software for structural equation modeling, was used to analyze data.

Findings

The results indicate that the audit committee component of CG has a significant positive impact on CSR dimension practices toward health, refugees, and community and environment. Furthermore, family members’ engagement in the board of directors and decision making plays a moderating role on the relationship between the audit committee and CSR practices toward health, community, and environment, as well as the relationship between the BOD and CSR toward community and environment.

Originality/value

The role of family members’ engagement in the effectiveness of CG and CSR practices FOE is studied.

Abstract

Purpose

Determining the attributes of effective business teachers is critical to schools as they strive to attract and retain students, assure learning, obtain and maintain reputation and accreditations, and place their alumni in the competitive job market. The purpose of this paper is to examine students and faculty perceptions of teaching effectiveness in five culturally disparate countries: Colombia, France, Lebanon, Sweden, and the USA.

Design/methodology/approach

A survey was designed based on previous research complemented by an extensive literature review as well as personal communications with faculty in different international business schools. The survey considered 39 teaching attributes related to three specific dimensions: class delivery, class preparation and design, and instructional traits and personal characteristics. The survey targeted students and faculty from seven business schools located in five countries.

Findings

This study offers new conceptual and analytical analyses from a cross-country comparative perspective. Rankings of the importance of perceived teaching attributes for both major groups involved in the teaching of business, faculty and students, are reported. The attributes are also ranked by teaching taxonomy and examined across countries.

Practical implications

This study provides practical results that can be useful to instructors wishing to increase their teaching effectiveness and to universities considering revising their student evaluation forms.

Originality/value

This study includes data collected from faculty and students from several schools located in culturally disparate countries and, thus, increases the applicability of the results in a cross-cultural manner and provides implications for practice internationally.

Abstract

Purpose

Sustainability focuses on the effect of present actions on societies, environments and ecosystems of the future. The purpose of this paper is to discover to what extent the MENA (Middle East and North Africa) region corporations carry out various aspects of corporate sustainability. This paper studies corporate sustainability practices and examines the association between corporate sustainability practices and performance in the MENA region.

Design/methodology/approach

A thorough literature review was conducted. The findings indicate six key categories/constructs that can be used as indicators for measuring corporate sustainability and performance. Based on the literature review, a theoretical framework was constructed and tested. Data for this quantitative and explanatory study were obtained through a self-administered survey which was distributed to senior managers at corporations in the MENA region.

Findings

The findings of this study show that the corporations operating in the MENA region are underachieving in all aspects of sustainability except for the energy management facet. Larger-sized companies tend to be more involved in corporate sustainability practices in the categories of internal and external education, external health and resources and energy management. This study finds the existence of a strong positive relationship between each sustainability category and each performance category.

Originality/value

Most studies on sustainability focus on North America, Europe and East Asia, not the MENA region. The findings will help corporations in the MENA region become aware of the importance of increasing their engagement in the sustainability aspects that they lack, as this will lead to a boost of their overall performance.

Abstract

Purpose

Research has shown that information and communication technologies (ICT) are crucial for economic growth. The purpose of this paper is to develop a framework that would depict and examine the nature of the relationship between ICT use and organizational performance in the Lebanese market, taking into consideration the impact that innovation and corporate entrepreneurship may have on this relationship.

Design/methodology/approach

To investigate the proposed model a survey targeting employees, and managers who adopted ICT applications in SMEs located in Lebanon was conducted.

Findings

The results indicate that ICT and innovation are strategic resources. However, their contribution to sustainable competitive advantage vitally depends on the implicitness and entrepreneurial behaviors of those involved. It is through this capability that ICT and ICT-based innovations could make a difference in organization’s performance – both present and future.

Research limitations/implications

First, the respondents were selected using the convenience sampling technique. Second, the data were collected through self-report questionnaires. Finally, the use of perceptual data related to performance may have a bias effect on the study results.

Practical/implications

At the practical level, the study results have repercussions for managers, technology suppliers, and innovation adopters and managers, as this may contribute to better understanding of the factors that could influence the adoption, management, and use of ICT resources for enhancing the competitiveness level of the firm.

Originality/value

The results of this study have implications for ICT adoption in Lebanese SMEs. More importantly, they suggest a framework which depicts the relationship between ICT and the organization’s innovation level on one hand, and a company’s performance on the other, taking entrepreneurship as a mediator in this relationship.

Abstract

Purpose

The purpose of this paper is to present an innovative agile methodology that proposes fundamental changes in managing the development of in-house information systems in small- and medium-sized enterprises (SMEs) and benchmarks it with one of two database technologies enabling these systems to be both efficient and competitive.

Design/methodology/approach

The objectives are achieved by presenting an elaborated design of the agile methodology that manages the system development process by addressing three basic components: roles played by system players, process needed to fulfill the system development, and artifacts to document the project. A case study is conducted as a proof of the effectiveness of the proposed methodology and measures whether the selection of the database technology affects the effectiveness of the system development process.

Findings

Results show that, compared with traditional methodologies, the proposed methodology reduced the cost of system development and testing by 30 percent and enhanced the IT – business alliance. Further, this work found that the selection of a suitable database technology is strongly related to the complexity and interrelationships between the data used.

Originality/value

Such research did not receive the needed attention (Hunter, 2004) even in the past decade. Successful adoption of IT by companies could be in the form of customized IS which could be expensive for SMEs to adopt due to a lack in technical expertise and financial resources. The proposed methodology has the potential to promote sustainable development through helping SMEs in reducing the time and cost of IT project development.
