• Gaining insight in domestic violence with Emergent Self Organizing Maps

      Poelmans, Jonas; Elzinga, Paul; Viaene, Stijn; Van Hulle, Marc; Dedene, Guido (+) (Expert Systems with Applications, 2009)
      Topographic maps are an appealing exploratory instrument for discovering new knowledge from databases. During the past years, new types of Self Organizing Maps (SOM) were introduced in the literature, including the recent Emergent SOM. The ESOM tool is used here to analyze a large set of police reports describing a wide range of violent incidents that occurred during the year 2007 in the Amsterdam-Amstelland police region (the Netherlands). This article aims to demonstrate that the ESOM tool provides a valuable exploratory instrument for examining unstructured text in police reports. First, it is shown how ESOM was used to discover a range of new features that better distinguish domestic from non-domestic violence cases. Second, it is demonstrated how this resulted in a significant improvement in classification accuracy. Third, the ESOM tool facilitates an in-depth investigation of the nature and scope of domestic violence, which is particularly useful for the domain expert. Interestingly, it was discovered that the definition of domestic violence employed by the management was much broader than the definition employed by police officers. Fourth, the ESOM tool enables an accurate and automated assignment of either a domestic or a non-domestic violence label to unclassified cases. Finally, ESOM is a highly accurate and comprehensible case triage model for detecting and retrieving wrongly classified cases.

    • Getting bang for your buck: The specificity of compensation and benefits information in job advertisements

      Verwaeren, Bart; Van Hoye, Greet; Baeten, Xavier (International Journal of Human Resource Management, 2017)
      Even though some organizations are trying to attract high-level applicants through offering superior compensation and benefits, reward statements in job advertisements are sometimes rather general and vague. On the basis of person-environment fit theories, we examine whether providing more specific information on attractive reward packages in job advertisements leads to higher perceived person-reward fit and subsequent job pursuit intentions. Furthermore, based on signaling theory, we propose that person-reward fit allows job seekers to make inferences about broader person-organization fit. Applying an online experimental design among 283 experienced potential applicants, we find that more specific compensation and benefits information results in higher job pursuit intentions and that this relationship is fully mediated by person-reward fit perceptions. In turn, the effect of person-reward fit is partially mediated by perceptions of person-organization fit, indicating that people might use reward information as signals for other organizational attributes in early stages of recruitment.

    • Global Compensation and Benefits Management: The Need for Communication and Coordination

      Baeten, Xavier (Compensation & Benefits Review, 2010)
      The author reports the results of a survey on global compensation management practices in multinational firms, most of them headquartered in continental Europe and the United Kingdom. The study focuses on whether decisions on different compensation and benefits issues in these firms are taken at a headquarters or at the regional, business unit or country/local level. In addition, the author provides more qualitative information on the degree to which the respondents are satisfied with the decision-making process as well as their concrete suggestions for improvement. Finally, the author deals with the question of whether centralization or decentralization is the preferable option.
    • Global dual sourcing and order smoothing: the impact of capacity and leadtimes

      Boute, Robert; Van Mieghem, Jan (Management Science, 2015)
      After decades of offshoring production across the world, companies are rethinking their global networks. Local sourcing is receiving more attention, but it remains challenging to balance the offshore sourcing cost advantage against the increased inventories, because of its longer lead time, and against the cost and (volume) flexibility of each source's capacity. To guide strategic allocation in this global network decision, this paper establishes reasonably simple prescriptions that capture the key drivers. We adopt a conventional discrete-time inventory model with a linear control rule that smoothes orders and allows an exact and analytically tractable analysis of single- and dual-sourcing policies under normal demand. Distinguishing features of our model are that it captures each source's lead time, capacity cost, and flexibility to work overtime. We use Lagrange's inversion theorem to provide exact and simple square-root bound formulae for the strategic sourcing allocations and the value of dual sourcing. The formulae provide structural insight on the impact of financial, operational, and demand parameters, and a starting point for quantitative decision making. We investigate the robustness of our results by comparing the smoothing policy with existing single- and dual-sourcing models in a simulation study that relaxes model assumptions.
    • Global value chains in Africa and development of opportunities by poor landholders

      Vermeire, Jacob; Bruton, Gary; Li, Cai (Review of Social Economy, 2017)
      In an effort to help address severe levels of poverty, multinational firms are increasingly seeking to include African smallholders in their global value chains (GVCs). Despite efforts of multinationals to provide such opportunities, the number of successful inclusions remains limited. We draw from the entrepreneurship domain to approach this important issue from an opportunity perspective. At the heart of our effort to develop a greater theoretical understanding is the insight that opportunities can both be discovered and created by smallholders. The key implication of this insight is that multinationals will gain more from their efforts to include small landholders in their GVCs if they adapt their value chain systems in ways that also accommodate joint creation of opportunities with smallholders rather than expect that all smallholders adapt to the systems developed by the large global firms for their large suppliers.

    • Going to the core of hard resource-constrained project scheduling instances

      Coelho, José; Vanhoucke, Mario (Computers and Operations Research, 2020)
      The resource-constrained project scheduling problem (RCPSP) is one of the most studied problems in the project scheduling literature, and aims at constructing a project schedule with a minimum makespan that satisfies both the precedence relations of the network and the limited availability of the renewable resources. The problem has attracted attention due to its NP hardness status, and different algorithms have been proposed that solve a wide variety of RCPSP instances to optimality or near-optimality. In this paper, we analyse the hardness of this problem from an experimental point-of-view by testing different algorithms on a huge set of existing instances and detect which ones are difficult to solve. To that purpose, we propose a three-phased approach that makes use of five elementary blocks, well-performing algorithms and a huge amount of computational power to transform easy RCPSP instances into very hard ones. The purpose of this study is to create insight and understanding into what makes an RCPSP instance hard, and propose a new dataset that consists of a small set of instances that are impossible to solve with the algorithms currently existing in the literature. These instances should be as small as possible in terms of number of activities and resources, and should be as diverse as possible in terms of network structure and resource strictness. Such a dataset should enable researchers to focus their attention on the development of radically new algorithms to solve the RCPSP rather than gradually improving current algorithms that can solve the existing RCPSP instances only slightly better.
    • Governance implications of attracting external equity investors in private family firms (Published Online)

      Neckebrouck, Jeroen; Meuleman, Miguel; Manigart, Sophie (Academy of Management Perspectives, 2018)
      While research commonly assumes business-owning families are concerned about the preservation of control, more and more families seek cooperation with external investors to accomplish firm- and/or family level-goals. In this paper, we provide a conceptual configuration of the different governance scenarios that may arise when family owners attract outside capital. Combining two important family objectives - the objective to provide liquidity either to the family or to the firm, and the objective to cede or to retain long-term family control - we identify four scenarios with different governance implications and preferred types of external investors. Our analysis contributes to an increased understanding of the evolving structures of ownership in private family firms, the effectiveness and efficiency of governance arrangements in family firm-external investor cooperations and the increasingly heterogeneous private equity funding landscape.
