• The impact of various activity assumptions on the lead-time and resource utilization of resource-constrained projects

      Debels, Dieter; Vanhoucke, Mario (2006)
      The well-known resource-constrained project scheduling problem (RCPSP) schedules project activities within the precedence and renewable resource constraints while minimizing the total lead-time of the project. The basic problem description assumes non-pre-emptive activities with fixed durations, and has been extended to various other assumptions in literature. In this paper, we investigate the effect of three activity assumptions on the total lead-time and the total resource utilization of a project. More precisely, we investigate the influence of variable activity durations under a fixed work content, the possibility of allowing activity pre-emption and the use of fast tracking to decrease a project's duration. We give an overview of the procedures developed in literature and present some modifications to existing solution approaches to cope with our activity assumptions under study. We present computational results on a generated dataset and evaluate the impact of all assumptions on the quality of the schedule.

    • The influence of topic involvement on mail survey response behavior

      De Wulf, Kristof; Van Kenhove, Patrick; Wijnen, Katrien (Vlerick Business School, 2003)
      This study experimentally investigated the influence of topic involvement on mail survey response rate and speed. The results show that response rates were higher for topics that are generally considered as high involvement than for topics that are generally considered as low involvement. Moreover, we observed an interesting interaction effect. On the one hand, a positive and significant relationship existed between topic involvement and response rate for topics that on average are viewed as high involvement, leading to a non-response bias. On the other hand, no significant relationship was found between topic involvement and response rate for topics that on average are viewed as low involvement. Finally, we were not able to observe a relationship between topic involvement and response speed for topics that are, on average, either high or low involvement.
    • The interface between corporate governance and corporate social responsibility and its relevance for the financial and insurance sector

      Van den Berghe, Lutgart; Louche, Céline (Vlerick Business School, 2004)
      Based on the argument that Corporate Social Responsibility is not just a fashion but rather the future from another angle, this paper explores the link between corporate governance and corporate social responsibility in insurance. Although insurance industries have been less exposed to criticisms than other sectors, like any other business, they are subject to increasing societal scrutiny. After a reconsideration of the corporate governance paradigms and mechanisms, the paper analyses the relevance of corporate social responsibility and corporate governance for the insurance sector. It explores its positive and negative externalities and its role as institutional investor. The paper also provides policy recommendations for mainstreaming corporate social responsibility within the sector.
    • The internationalization of small and medium-sized firms: the role of organizational learning effort and entrepreneurial orientation

      De Clercq, Dirk; Sapienza, Harry J.; Crijns, Hans (Vlerick Business School, 2003)
      This paper contributes to the existing research by integrating the notions of organizational learning and entrepreneurial orientation into the body of international entrepreneurship. Our primary framework combines learning theory and the new venture theory of internationalization to study the extent to which small and medium-sized companies engage in international activities. In order to focus on firms likely to engage in significant cross-border activity, we used a survey instrument to collect data from small and medium-sized firms located in Belgium. We found that the firms' international learning effort and entrepreneurial orientation are positively associated with internationalization intent whereas domestic learning effort is negatively related with internationalization intent. Overall, our results suggest (1) that intensive knowledge renewal and exploitation regarding foreign markets and the internationalization process itself may increase internationalization by affecting the perceptions of opportunities offered by further international expansion, and (2) that firms with an entrepreneurial mindset may be more likely to develop a long-term, substantial presence in the international arena, compared to firms that are more reactive or conservative. However, our results also suggest that firms that invest in domestic learning activities, as opposed to international learning activities, may be less likely to internationalize further.
    • The job challenge construct revisited: conceptualization, antecedents, and consequences of experienced challenge and overchallenge in the job

      Dewettinck, Koen; Buyens, Dirk (2006)
      In this study, we propose a conceptual model on individual and job-contextual antecedents, and affective and behavioral employee consequences of experienced job challenge and overchallenge. Based on a sample of 511 frontline employee - supervisor dyads, we found that autonomy in the job and outcome control are positively related to experienced job challenge and that internal locus of control, autonomy and behavioral control are negatively related to overchallenge. While challenge shows to have a consistent positive impact on employee affect and behavioral intentions, overchallenge has a consistent negative impact on the same outcome variables. Challenge and overchallenge did however not relate to effectiveness levels as rated by the supervisor. Theoretical and managerial implications are discussed. Keywords: frontline employee, job challenge, stress, control, employee performance
    • The joint effects of customer profitability reports and sales support diversity in effective customer pricing

      Cardinaels, Eddy; Roodhooft, Filip; Warlop, Luk; Van Herck, Gustaaf (Vlerick Business School, 2004)
      This paper experimentally investigates the value-enhancing effects of more accurate customer profitability analysis (CuPA) reports on customer pricing decisions and firm profitability when customers place different demands on the firm's support functions. Activity-based driven CuPA reports are contrasted against less accurate reports, either based on traditional volume-based costing or on aggregated feedback. Cost complexity of the environment was further varied by either low or high diversity in resource usage across customers depending on whether or not the most costly type of customer always consumed more resources in each of the various support functions of the firm. Results suggest that the diversity in resource requirements serves as an important 'contextual factor' for CuPA to have incremental value over the less accurate report types. Only when usage of sales support becomes more diverse, CuPA provides strong opportunities for learning resulting in more effective customer pricing and profit improvement. Results further show some profit benefits of volume-based costing reports. Even though cost allocations are more distorted, they still perform better than aggregated reports that do not allocate marketing overhead, but only in a more complex cost settings.

    • The manufacturing profile of flexible and low-cost producers: an empirical study

      Vereecke, Ann; Pandelaere, Els (Vlerick Business School, 2004)
      Since the introduction of the concepts of lean manufacturing, agility and mass customization it is questioned to what extent the trade-off between cost and flexibility still holds. It has been the objective of our research to test the trade-off theory empirically using the data of the International Manufacturing Strategy Survey (IMSS). Our research confirms the well accepted manufacturing profile of low cost producers, which typically use a line process, and of flexible producers, which typically produce in a job shop. However, we also observe that some companies manage to overcome the cost/flexibility trade-off, by introducing the concept of postponed manufacturing. These companies are characterized by an assembly-to-order policy of standardized semi-finished products, produced in a line process. Flexibility and low cost are thus obtained by playing with the position of the decoupling point. Keywords: manufacturing strategy, mass customization, flexibility

    • The moderating impact of relational strength on the relationship between relationship quality and purchasing behavior

      De Cannière, Marie; De Pelsmacker, Patrick; Geuens, Maggie (2006)
      We investigate the moderating impact of relational strength on the relationship quality model, that is extended from intentions onto real behaviour. Empirical investigations are conducted in the context of apparel buying, combining survey and data base information. Relational strength impacts the attitudes-intentions as well as the intentions-behavior relationship. The opposite signs of the effects may explain disappointing results when relationship quality is used to boost behavioral loyalty.
    • The Ooghe-Joos-De Vos failure prediction models : a cross-industry validation

      Ooghe, Hubert; Camerlynck, Jan; Balcaen, Sofie (UGent, Fac. Economie & Bedrijfskunde, 2001)
      This study tests the validity of the Belgian Ooghe-Joos-De Vos (1991) failure prediction models (1 and 3 years prior to failure) across 18 different industries and different size classes. Firstly, the performance results and the trade-off functions reveal a wide range of performances for the different industries. However, we notice that the OJD models perform best for the classical manufacturing industries and financial services, while they show the worst performance results for the service industries and the no-industry category. Furthermore, when using new, industry specific cut-off points, the error rates of the models are significantly reduced. Secondly, the OJD model 1 year prior to failure seems to perform best for large companies and companies with complete form annual accounts. Finally, the performance differences between the various subgroups with respect to industry, size class and form of annual account of the model 3 years prior to failure the are much smaller than those of the model 1 year prior to failure.
    • The operating theatre as a key to improved hospital operations

      Cardoen, Brecht (2012)
      In search of an answer to the question to what degree context determines human resource management (HRM) practices, a holistic picture of contextual factors seems indispensable. However, due to ample interpretations and the vague characterization of this construct, a self-revealing definition seems impossible. In order to address this dilemma, we firstly tackle the need for a discussion on what context is and, secondly, how it is embedded in the field of international comparative Human Resource Management. We start this paper with a short summary of the Universalistic versus Contextual Perspective on the one hand, and the Convergence versus the Divergence paradigm on the other. We discuss the influence of context within both debates. Secondly, we elaborate on the mapping of the construct of context by scrutinizing the relevant literature within the international comparative HRM field. Thirdly, the link between this construct and the Cranet Network is investigated. Finally, the usefulness of the Cranet data, in light of the contextual, is discussed with the focus on future research and its practicability in further research endeavors.
    • The optimal rating philosophy for the rating of SMEs

      Rikkers, Frieda; Thibeault, André (2007)
      The objective of this research is to determine the optimal rating philosophy for the rating of SMEs, and to describe the consequences of the chosen philosophy on several related aspects. As to our knowledge, this is the first paper that studies the considerations of financial institutions on what rating philosophy to adopt for specific portfolios. The importance for banks to have a solid risk framework to predict credit risk of their counterparties is well reflected by the quality and the quantity of research on this subject. Moreover, a good risk framework is vital to become compliant with the new Basel II framework. Problem is that financial institutions nearly always neglect the first step in the rating model development process: the determination of the rating philosophy. It is very important for financial institutions to decide whether they want their internal rating systems to grade borrowers according to their current condition (point-in-time), or their expected condition over a cycle and in stress (through-the-cycle), because the rating philosophy influences many aspects such as: credit approval, pricing, credit and portfolio monitoring, the regulatory and internal capital requirements and the competitive position of a bank. This makes the question which rating philosophy to use very important. Moreover, many different modelling techniques exist to determine credit risk, but few attempts have been devoted to credit risk assessment of small commercial loans, although SME exposures are relatively important for European banks. SMEs have specific characteristics that influence the rating philosophy and therefore the development and use of credit risk models. These SME characteristics are taken into account in the analysis to determine the optimal rating philosophy.
