    • Openness to organizational change: the contribution of content, context, and process

      Devos, Geert; Buelens, Marc (Vlerick Business School, 2003)
      The present study examined the contribution to employees' openness to change of the content, context, and process of organizational transformation. The threatening character of organizational change (content variable), trust in executive management, trust in the supervisor, history of change (context variables), and participation in the change effort (process variable) were predicted to have a positive effect on openness to change. Hypotheses were tested in two separate studies (N = 828 and N = 835) using experimental vignettes. A first study crossed four variables in a fully crossed 2 × 2 × 2 × 2 design. Results showed significant main effects and no interaction effects for content, context, and process. A second study, with a fully crossed 2 × 2 design crossed two context variables, history of change and trust in top management. Results showed significant main and significant interaction effects. It was only when history of change and trust in executive management were low that openness to change dramatically decreased.
    • Optimal due date assignment in project scheduling

      Vanhoucke, Mario (Vlerick Business School, 2002)
      In this paper we introduce the concept of due date assignment in the project scheduling literature. Despite the fact that due date assignment problems belongs to the core of the machine scheduling literature, no attempts have been made to tackle this problem in a project scheduling environment. However, of obvious practical importance, an optimal assignment of due dates is of primary interest to the project manager. In a recent research paper on project scheduling with due dates, the problem has been restricted to considering projects with pre-assigned due dates. In reality, due dates are the results of negotiations, rather than simply dictated by the client of the project. In this paper we consider this negotiation process and take a contractor's point of view who faces the problem of assigning due dates to a particular project, based on the negotiation arguments of the client. We show that the problem under study can be solved by means of the combination of different ideas from the operations research community.

    • Organizational versus individual responsibility for career management: complements or substitutes

      De Vos, Ans; Buyens, Dirk (Vlerick Business School, 2005)
      This paper explores the relationship between organizational career management and career self-management and addresses their impact on employee outcomes. The results of a study among employees and linemanagers are presented, which partly support our hypotheses. The interaction between organizational and individual career management in explaining employee outcomes is discussed.
    • Outside board members in the high-tech start-ups

      Clarysse, Bart; Knockaert, Mirjam; Lockett, Andy (2006)
      Board composition in large organizations has been subject to much empirical research, however, little attention has been focused on board composition in start-ups, and more specifically high tech start-ups. This lack of research is surprising given that many high tech start-ups have multiple equity stakeholders such as venture capitalists or public research organizations, such as universities. Given that high tech start-ups are commonly resource-poor these external stakeholders may play an important role in accessing critical external resources. Drawing on agency theory, resource dependence theory and social network theory we examine the tensions that exist between the founding team and external equity stakeholders in determining the presence of outside board members. In particular we focus on whether or not the outside board members have either complementary or substitute human capital to the founding team. We test our model on a sample of 140 high tech start-ups in Flanders. Our results indicate that high tech start-ups with a public research organization as an external equity stakeholder are more likely to develop boards with outside board members with complementary skills to the founding team. Conversely, in high tech start-ups where the founding team has had autonomy, or where a venture capitalist is an external equity stakeholder, the board tends to consist of outside board members with similar or substitute human capital to the founding team. Our findings the presence of an external equity stakeholder does not guarantee that outside board members have complementary human capital to the founding team.

    • Practitioner's view on project performance: a three-polar construct

      Vandevelde, Anneke; Van Dierdonck, Roland; Debackere, Koenraad (Vlerick Business School, 2002)
      There is no consensus on the construct project performance. This article examines how to suitably operationalise ‘project performance' as it is viewed by practitioners. An alternative research approach, based on the repertory grid method, was used in combination with a survey to develop a three-polar framework of the construct project performance. The model stresses that the construct should be considered as multidimensional, including process, economic and indirect poles. It promotes a balance between financial and non-financial measures, between short- and long-term measures, between measures focusing on the past and measures directed at the firm's future drivers. The model confirms and enriches the existing research on project performance.
    • Pre-acquisition profile of privately held companies involved in takeovers: an empirical study

      Ooghe, Hubert; Camerlynck, Jan (Vlerick Business School, 2001)
      This study addresses the pre-acquisition financial characteristics of privately held acquiring and acquired companies involved in 143 Belgian takeovers between 1992 and 1994. Specifically, the research examines the profitability, liquidity, financial structure, added value and failure risk using statistical analysis of industry-adjusted variables. Our findings show that acquisition is not an alternative to bankruptcy since acquired companies do not report high failure risk, but exhibit higher than industry liquidity and solvency. The acquirers achieve a higher growth rate in total assets and sales than the acquired firms but experience a negative industry-adjusted liquidity and are highly levered, suggesting evidence for a growth-resource mismatch or a financial fit between acquirers and their targets.
    • Pre-emptive resource-constrained project scheduling with setup times

      Debels, Dieter; Vanhoucke, Mario (2006)
      Resource-constrained project scheduling with activity pre-emption assumes that activities are allowed to be interrupted and restarted later in the schedule at no extra cost. In the current paper, we extend this pre-emptive scheduling problem with setup times between activity interruptions and the possibility to fast track pre-emptive subparts of activities. The contribution of the paper is twofold. First, we present an optimal branch-and-bound procedure for the pre-emptive resource-constrained project scheduling problem with setup times and fast tracking options. Second, we test the impact of these pre-emptive extensions to the quality of the schedule from a lead-time point-of-view.

    • Profile Of Multiple Versus Single Acquirers And Their Targets: A Research Note

      Ooghe, Hubert; De Langhe, Tine; Camerlynck, Jan (Vlerick Business School, 2003)
      Few studies have addressed the pre-take-over financial characteristics of multiple versus single acquirers and their targets. Therefore this study investigates whether multiple acquirers, with some experience in acquiring companies, might acquire firms with different (better) financial characteristics than single acquirers. Our results confirm this hypothesis in multiple ways. It seems that multiple acquirers look for complementary firms in terms of sales and growth. Multiple acquirers specifically want to acquire companies with a high sales generating ability in order to improve their own sales generating ability.
    • Protecting customer privacy in the financial sector

      Isik, Öykü; Dupire, Marion (CFSI, 2016)
      With increased digitization of the financial sector comes the issues of data protection and customer privacy. Banks collect huge amounts of data on individuals, notably from bank accounts, credit card transactions or mobile ranking. On the one hand the use of big data in the financial sector is a wonderful opportunity to better respond to customer needs. The biggest hurdle on the other hand is customer privacy and data protection. How can financial institutions most efficiently deal with customer privacy when making use of digital technologies? How should they deal with the issue of privacy given the current context where rebuilding trust is a key challenge? These are the main questions addressed in this policy paper which consists in two part. The first part is a contribution of Pr. Öykü Isik providing a state-of-the-art of data-driven financial services. The second part is the report of a Vlerick regulatory workshop dedicated to the topic gathering representatives from different horizons within the financial sector including regulatory authorities, banks, insurance companies, financial associations, consulting companies, law firms. The second part of the paper provides a detailed overview of workshop presentations, discussions, and co-creation exercise.
    • Psychological contract development during organizational socialization: adaptation to reality and the role of reciprocity

      De Vos, Ans; Buyens, Dirk; Schalk, M.J.D. (René) (Vlerick Business School, 2003)
      Based on the theoretical framework of newcomer sensemaking this study examines factors associated with changes in newcomers' psychological contract perceptions during the socialization process. More specifically, two mechanisms are addressed that could explain changes in newcomers' perceptions of the promises they have exchanged with their employer: (1) unilateral adaptation of perceived promises to reality and (2) adaptation of perceived promises as a function of the reciprocity norm. To test our hypotheses, a four-wave longitudinal study among 333 new hires has been conducted, covering the first year of their employment relationship. Results show that changes in newcomers' perceptions of the promises they have made to their employer are affected by their perceptions of their own contributions as well as by their perceptions of inducements received from their employer. Changes in newcomers' perceptions of employer promises are affected by their perceptions of employer inducements received, but the impact of perceived employee contributions is less clear. The data provide limited support for the idea that the adaptation of perceived promises to perceived inducements and contributions occurs to a stronger extent during the encounter stage than during the acquisition stage of socialization.
