Work-related reproductive health: a review

This paper reviews the literature concerning the impact of work on reproductive health. In doing so, it offers a framework model for guiding future research and practice. Contemporary models of occupational health usually identify at least two pathways linking exposure to workplace hazards to their effects on health. The study of work-related reproductive health has been largely restricted to the effects of the more tangible and physical hazards of work mediated by a largely physico-chemical pathway. However, the growth of research into the psycho-physiological influence of stress on reproductive health provides a new direction for research in this domain with the exploration of a complementary pathway. The extension of this new approach into the investigation of the effects of work design and management on reproductive health represents a potentially important and further development.

Incorporating multiple levels of analysis into occupational stress research

In recent years, more and more research in the organizational sciences has incorporated a multiple levels of analysis perspective (e.g. individual, group and organizational) into models of organizational behaviour. The study of occupational stress, however, has continued to focus almost exclusively on the individual level of analysis. In this paper, the authors contend that incorporating a multi-level perspective in the study of occupational stress has theoretical as well as practical value. The authors illustrate their position using results from an occupational stress research programme conducted by the Walter Reed Army Institute of Research.     

A Public Transportation Decision‐Making Model within a Metropolitan Area

Understanding the decision‐making factors associated with public transportation is essential in strategic development of public transportation to improve acceptance and utilization of mass transit systems. This research analyzes factors affecting attitudes toward public transportation and the choice of transportation mode by investigating the public transportation decision‐making process of working professionals using a survey methodology. The objectives of this research are to model the transportation decision‐making process of public transportation users in a metropolitan area and to determine key factors that affect the public transportation choices made by potential public transportation users. This study contributes to the literature by developing and testing an integrated theoretical framework for modeling an individual's public transportation decision‐making process using four independent variables: Perceived Public Transportation Security, Knowledge, Price, and Convenience. We develop the proposed theoretical framework based upon the extant literature and tested it using partial least squares structural equation modeling (PLS‐SEM). Based on the Theory of Reasoned Action, the Theory of Planned Behavior, and utility theory, we develop the factors and refine associated items using confirmatory factor analysis.     

SERVICE SYSTEM DESIGN FOR THE PROPERTY AND CASUALTY INSURANCE INDUSTRY

This paper describes the changes that are forcing property and casualty insurance firms to rethink their service system design and in particular their distribution strategies. A set of questions related to distribution that are uppermost in the minds of executives in this industry are presented along with a literature survey of models that can be used to answer some of these questions. Based on the survey, a normative framework for designing the distribution system is proposed. Qualitative and quantitative analysis based on the proposed framework is presented along with empirical data to demonstrate the usefulness of the framework. The paper concludes with an agenda for further research.     

The Relationship Between Information System Planning Sophistication and Information System Success: An Empirical Assessment*

Literature on information systems (IS) planning implicitly assumes that a sophisticated IS planning process leads to greater IS success. This paper questions the exclusive reliance on this traditional belief. Instead, because IS planning requires significant organizational resources, prior IS success is essential to convince top management of the importance of IS planning sophistication. Therefore, IS success may influence IS planning sophistication. Several theoretical arguments are advanced in support of this explanation. Data from a survey of 236 academic institutions are used to empirically assess the two alternative directions of the relationship between IS planning sophistication and IS success. Four structural models including the alternative causal directions are evaluated. Two of these models are supported. Together, they imply that for a high level of IS planning sophistication, either the previous ISs should have been successful or the organization should possess advanced information technology capabilities. Thus, empirical results suggest that the explanation presented here (i.e., IS success facilitates IS planning sophistication) provides an equally good alternative to the more traditional explanation (i.e., IS planning sophistication facilitates IS success).     

Resource constraints and information systems implementation in Singaporean small businesses

While the information systems (IS) literature has identified potential factors of IS implementation success, none has investigated the relative importance of these factors in the context of small businesses. Small businesses have very different characteristics from large businesses; notably, small businesses suffer from resource poverty. Without knowing the relative importance of key factors, small businesses may be expending their limited resources and energy on less important factors which have limited contribution to IS implementation success. This paper develops a resource-based model of IS implementation for small businesses based on Welsh and White's (Harv Bus Rev 59(4) (1981) 18–32) framework of resource constraints in small businesses and Attewell's (Organ Sci 3(1) (1992) 1–19) knowledge barrier theory. The model is then tested on a sample of 114 small businesses. The results show that small businesses with successful IS tend to have highly effective external experts, adequate IS investment, high users’ IS knowledge, high user involvement, and high CEO support. External expertise is the predominant key factor of IS implementation success in small businesses.     

The Job Demand-Control (-Support) Model and psychological well-being: A review of 20 years of empirical research

The Job Demand-Control (JDC) model (Karasek, 1979) and the Job Demand-Control-Support (JDCS) model (Johnson, and Hall, 1988) have dominated research on occupational stress in the last 20 years. This detailed narrative review focuses on the JDC(S) model in relation to psychological well-being. It covers research from 63 samples, published in the period 1979-1997. In the review a distinction is drawn between two different hypotheses prevailing in research on the models. According to the strain hypothesis of the JDC model, employees working in a high-strain job (high demands-low control) experience the lowest well-being. The buffer hypothesis states that control can moderate the negative effects of high demands on well-being. Translating these hypotheses to the expanded JDCS model, the iso-strain hypothesis predicts the most negative outcomes among workers in an iso-strain job (high demands-low control-low social support/isolation), whereas the buffer hypothesis states that social support can moderate the negative impact of high strain on well-being. Although the literature gives considerable support for the strain and iso-strain hypotheses, support for the moderating influence of job control and social support is less consistent. The conceptualization of demands and control is a key factor in discriminating supportive from nonsupportive studies. Only aspects of job control that correspond to the specific demands of a given job moderate the impact of high demands on well-being. Furthermore, certain subpopulations appear to be more vulnerable to high (iso)strain, whereas others benefit more from high control. On the basis of the results of this review, suggestions for future research and theoretical development are formulated.

Institutional voids and firms' resource commitment in emerging markets: A review and future research agenda

The impact of institutional environments on firms' strategic decisions has been examined in strategy and international business literature. Yet, the current state of knowledge about how institutional voids affect firms' resource commitment in emerging markets is equivocal. This paper reviews and develops an integrative framework that maps the key conceptualizations, theoretical frames, mechanisms, contingencies and outcomes in the institutional voids – resource commitment literature. Altogether, this paper structures institutional voids and resource commitment research into salient themes to help scholars scope the field and explore value-adding avenues to further our understanding of internationalization and resource commitment decisions in emerging markets.     

The wider implications of business-model research

Business-model research has struggled to develop a clear footprint in the strategic management field. This introduction to the special issue on the wider implications of business-model research argues that part of this struggle relates to the application of five different perspectives on the term “business model,” which creates ambiguity about the conceptual boundaries of business models, the applied terminology, and the potential contributions of business-model research to strategic management literature. By explicitly distinguishing among these five perspectives and by aligning them into one overarching, comprehensive framework, this paper offers a foundation for consolidating business-model research. Furthermore, we explore the connections between business-model research and prominent theories in strategic management. We conclude that business-model research is not necessarily a “theory on its own” and that it can be more fruitfully understood as a theoretical mechanism for combining different literature streams. As such, business-model research is positioned as a central connecting component in the further development of the strategic management field.     

The importance of context specificity in work stress research: A test of the Demand-Control-Support model in academics

The Demand-Control (D-C) (Karasek, 1979) and the Demand-Control-Support (D-C-S) (Johnson & Hall, 1988; Johnson, Hall, & Theorell, 1989; Karasek & Theorell, 1990) models of work stress suggest that jobs with high demands and low control (and low support) are stressful. In line with the support in the literature for context-specificity in occupational stress research (Sparks & Cooper, 1999) and the limited and even contradictory support for interaction effects, the main aim of the present study was to examine how the D-C-S model applied in a well-defined occupational group. Using hierarchical regression analyses, and controlling for negative affect, the D-C-S model accounted for 26%, 6%, and 8% of the variance in job satisfaction, psychological distress and burnout, respectively, among 166 academics in a UK university. No two-way or three-way interactive effects were evident, but additive effects of job demands and control on psychological well-being and of job demands and support on both burnout and job satisfaction were shown, corroborating research showing that high job strain is linked to ill health and job dissatisfaction in this homogenous occupational sample. It is recommended that, in future, research includes more variables that are specific to a particular occupation.     

Understanding the Antecedents of Effective Knowledge Management: The Importance of a Knowledge‐Centered Culture*

Within the context of knowledge management, little research has been conducted that identifies the antecedents of a knowledge‐centered culture—those organizational qualities that encourage knowledge creation and dissemination. In this study, the existing literature on organizational climate, job characteristics, and organizational learning (in the form of cooperative learning theory) are linked with the current thinking and research findings related to knowledge management to develop a theoretical model explaining the relationships among organizational climate, the level of cooperative learning that takes place between knowledge workers, and the resulting level of knowledge created and disseminated as measured by team performance and individual satisfaction levels. The study goes on to empirically test the proposed research model by investigating the climate of organizations, and seeks to understand the linkage between a set of organizational and individual characteristics and knowledge‐related activities found in cooperative learning groups and the resulting work outcomes. The hypothesized research model is tested using LISREL with data collected from 203 information systems (IS) professionals engaged in systems development activities. The paper concludes with a discussion of the implications the results have for future research and managerial practice.     

A review of empirical research on dynamic competitive strategy

Beginning with Chandler's 1962 seminal work, researchers have emphasized that competitive strategy is not a static phenomenon, but rather a sequence of interconnected actions and reactions unfolding over time. This paper reviews the empirical research on dynamic competitive strategy published between 1986 and 2005 in nine leading strategic management journals. An integrated framework is used to showcase the research in terms of antecedents, strategic actions and outcomes. The literature review demonstrates that significant progress has been made in the field of dynamic competitive strategy, and yet that there are still many promising lines of inquiry for future theoretical and empirical research, particularly in the areas of strategic action timing and path dependency.     

A literature review and emotion-based model of age and leadership: New directions for the trait approach

Despite renewed interest in traditional trait approaches to leadership and despite recent demographic trends towards an aging workforce, research on leaders' age as a specific demographic trait variable has remained surprisingly sparse and fragmented. This article provides a comprehensive review of the empirical literature on this issue. Although a body of research relating leaders' age with their behaviors and outcomes has emerged, the existing findings exhibit little consistency and lack theoretical coherence. Integrating theories of emotional aging with research on emotions and leadership, we therefore develop a novel, emotion-based framework that explicates key mechanisms and boundary conditions underlying age–leadership linkages. Moreover, we outline opportunities for further theoretical extensions and provide recommendations for future empirical work. Overall, this article paves new ground for contemporary research on leadership traits by highlighting the relevance of leaders' age, summarizing current knowledge on this issue, and providing new theoretical and empirical directions.     

The importance of context specificity in work stress research: A test of the Demand-Control-Support model in academics

Abstract

The Demand-Control (D-C) (Karasek, 1979) and the Demand-Control-Support (D-C-S) (Johnson & Hall, 1988; Johnson, Hall, & Theorell, 1989; Karasek & Theorell, 1990) models of work stress suggest that jobs with high demands and low control (and low support) are stressful. In line with the support in the literature for context-specificity in occupational stress research (Sparks & Cooper, 1999) and the limited and even contradictory support for interaction effects, the main aim of the present study was to examine how the D-C-S model applied in a well-defined occupational group. Using hierarchical regression analyses, and controlling for negative affect, the D-C-S model accounted for 26%, 6%, and 8% of the variance in job satisfaction, psychological distress and burnout, respectively, among 166 academics in a UK university. No two-way or three-way interactive effects were evident, but additive effects of job demands and control on psychological well-being and of job demands and support on both burnout and job satisfaction were shown, corroborating research showing that high job strain is linked to ill health and job dissatisfaction in this homogenous occupational sample.

Lot-sizing decisions under limited-time price incentives: A review

The problem of determining the optimal order quantities for an inventoried item, when the vendor offers a limited-time price reduction is both interesting and important. It is interesting in that it has received continued attention of academic researchers for over four decades and it is important given its economic implication in a variety of practical settings. The extensive literature on this problem represents a fascinating confluence of: (1) economic significance and relevance to managerial practice, (2) continuing academic research interest directed at precise mathematical analysis leading to the development of rigorous and complex models and policies, and (3) elegance and adequacy of simple models and heuristic policies which are validated by the results of rigorous models and computational analysis. In this paper, we survey this literature using simple classification frameworks and then review some of the key studies. We highlight their key assumptions and findings, bring across key implications for policy implementation and academic research and identify avenues for further research.     

Multi‐Leader Teams in Review: A Contingent‐Configuration Perspective of Effectiveness

Multi‐leader teams are characterized by multiple leaders exhibiting mutual influence on each other while working towards a common team goal. An unexplored assumption in this literature is that increasing the number of leaders is related to heightened team effectiveness. The authors propose that this notion is oversimplified and suggest a contingency model of multi‐leader team effectiveness. The authors suggest that the context determines the effectiveness of a particular multi‐leader team configuration, because each formation has unique internal team mechanisms. To investigate this perspective, we review the multi‐leader team literature (175 articles) by categorizing the extant theory and research as falling within nine multi‐leader configurations along two key dimensions: (1) the proportion of leaders within a team; and (2) the dispersion of leadership through role co‐enactment of team leaders. This framework enables a more coherent understanding as to the benefits and the costs of each specific multi‐leader team configuration and a clearer evaluation of the contexts in which varying configurations are most effective. Four emerging themes related to configuration–contextualization are explained and theoretical implications for interpreting leadership effectiveness in multi‐leader team settings are discussed.
