Abstract
Schedule instability is a major problem in companies using material requirements planning (MRP) systems. The effectivenesss of using buffer stock to combat nervousness in the master production schedule (MPS) of an MRP system is investigated. An example scenario illustrates the need for caution in using buffer stock for reducing schedule instability. Detailed simulation results are presented which suggest the need for further research to understand the role of buffer stock in achieving stable master production schedules.

Abstract
Cellular manufacturing is the organisation of manufacturing equipment based on the requirements of the product or component. Transition to cellular manufacturing generally requires reorganisation of existing equipment. It is likely that the existing equipment alone is not suitable for a cellular layout. During the cell planning and design phase equipment investment analysis is important to identify equipment needs. Transition from job shop production to cellular production is detailed. Cell formation and cell evaluation techniques are provided to assist in equipment procurement decisions. In particular, a structured procedure and analytical tools are given to evaluate fully the cellular system to identify appropriate equipment and methods. A case example is provided to explain the procedure.

Abstract
Purpose
Changes frequently made to material delivery schedules (MDSs) accumulate upstream in the supply chain (SC), causing a bullwhip effect. This article seeks to elucidate how dynamic complexity generates MDS instability at OEMs in the automotive industry.
Design/methodology/approach
An exploratory multiple-case study methodology involved in-depth semistructured interviews with informants at three automotive original equipment manufacturers (OEMs).
Findings
Dynamic complexity destabilizes MDSs primarily via internal horizontal interactions between product and process complexities and demand and SC complexities. A network of complexity interactions causes and moderates such instability through complexity absorption and generation and complexity importation and exportation.
Research limitations/implications
The multiple-case study contributes to empirical knowledge about the dynamics of MDS instability. Deductive research to validate the identified relationships remains for Future research.
Practical implications
In revealing antecedents of complexity’s effect on MDS instability, the findings imply the need to develop strategies, programs, and policies dedicated to improving capacity scalability, supplier flexibility, and the flexibility of material order fulfillment.
Originality/value
Building on complexity literature, the authors operationalize complexity transfer and develop a framework for analyzing dynamic complexity in SCs, focusing on complexity interactions. The identification and categorization of interactions provide a granular view of the dynamic complexity that generates MDS instability. The identified and proposed importance of readiness of the SC to absorb complexity challenges the literature focus on external factors for explaining complexity outcomes. The results can be used to operationalize such dynamic interactions by introducing new variables and networks of relationships. Moreover, the work showcases how a complexity perspective could be used to discern the root causes of a complex phenomenon driven by non-linear relationships.

Abstract
Purpose
Literature in entrepreneurial marketing (EM) continues to grow in volume and diversity. This paper aims to examine the topical structure of EM’s literature toward guiding research in the field.
Design/methodology/approach
A four-phase bibliometric research design is implemented, encompassing co-citation and bibliographic-coupling analyses, network analysis, factor analysis and correspondence analysis.
Findings
In total, 14 EM literature clusters, comprising 7 topical meta-clusters, are mapped and discussed: the 7 clusters are resources and capabilities, entrepreneurial orientation (EO), measurement, EO/marketing orientation (MO) integration, MO, international entrepreneurship and social entrepreneurship.
Originality/value
These topical streams confirm, refine and extend prior bibliometric studies. A more comprehensive, extensive and reliable picture of EM’s literature is provided, the result of using over twice as many references as prior studies and peer-reviewed journals only. Results will help guide EM research, contributing toward the field’s empirical/theoretical development.

Abstract
Purpose
In recent years, student-managed investment funds (SMIFs), experiential learning programs at an increasing number of universities, have attracted significant scholarly interest. In this article, we review the academic literature on this pedagogy.
Design/methodology/approach
We use the systematic review method to assess a sample of 85 articles published in 30 journals during the period 1975 to 2020.
Findings
Our literature review reveals four streams of research: best practices and challenges, investment management, innovation and trends and SMIFs in a research setting. We also propose future research directions, including specific gaps in the literature, a focus on innovations to traditional programs, systematic investment performance and expansion into behavioral finance issues.
Originality/value
We contribute a comprehensive view of the body of scholarship on SMIFs, identifying existing streams of research and future research directions that will help guide the development of SMIF research into a cohesive and productive space.

Abstract
Purpose
The purpose of the paper is to provide a conceptual/theoretical foundation to enhance the body of knowledge related to supply chain interdependence and technology‐enabled coordination.
Design/methodology/approach
The paper heavily engaged itself in the theory/literature related to coordination theory, interdependence theory, interdependence, coordination and supply chain technologies to formulate the theoretical propositions.
Findings
From the literature/theoretical bases, the paper derived a total (include sub‐components) of eight theoretical propositions related to interdependence, coordination and technology enablers.
Research limitations/implications
While technology enabled‐coordination is central to supply chain management, there is a lack of a prescriptive view present in the literature. By deriving insights from the rich literature related to coordination theory and interdependence theory, we provide a theoretical foundation for future research to enhance the body of knowledge related to the systematic application of technology to foster the appropriate coordination strategy.
Practical implications
Although empirical support is warranted, the proposed concepts related to technology‐enabled coordination offer pragmatic advice to managers.
Originality/value
The paper provides a theoretical foundation for future research to enhance the body of knowledge related to the systematic application of technology to foster the appropriate coordination strategies.

Abstract
Sales personnel play a key role in the success of organizations. These individuals present services/products to clients, manage accounts, build relationships, maintain existing business relationships, and must be available for frequent interactions with clients. Business operations are linked to external entities through these activities, suggesting sales groups play a critical role in the success of an organization. As a representative to the external market, sales personnel are subject to unique stressors due to role-specific requirements. These stressors can impact the ability of sales professionals to effectively engage with customers and manage the volatility of financial performance, especially in commission-based compensation structures. Thus, organizations can find utility in identifying sales candidates with higher levels of stress tolerance, who can handle negative client interactions, overcome lulls in sales conversions, and avoid the impact of occupational stressors on long-term sales performance. Research suggests that organizations can use personality to predict stress tolerance as a component of sales performance. To provide organizations with insights into sales-specific coping behaviors associated with stress tolerance, the authors (1) discuss stress inducing factors (stressors) associated with sales role performance, (2) review the individual differences associated with stress tolerance, (3) present personality relationships with sales performance and stress tolerance, and (4) present job-analytic support for stress tolerance competencies relevant to sales performance and criterion-related validity evidence linking personality characteristics to those behaviors. The authors conclude with a discussion around the potential for applied uses of personality in identifying sales personnel with greater likelihoods of exhibiting stress tolerant behaviors in the workplace.
