• 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.

    • Generalized multi-scale stochastic reservoir Opportunity Index for enhanced well placement optimization under uncertainty in green and brownfields

      Vaseghi, Forough; Ahmadi, Mohammad; Sharifi, Mohammad; Vanhoucke, Mario (Oil & Gas Science and Technology, 2021)
      Well placement planning is one of the challenging issues in any field development plan. Reservoir engineers always confront the problem that which point of the field should be drilled to achieve the highest recovery factor and/or maximum sweep efficiency. In this paper, we use Reservoir Opportunity Index (ROI) as a spatial measure of productivity potential for greenfields, which hybridizes the reservoir static properties, and for brownfields, ROI is replaced by Dynamic Measure (DM), which takes into account the current dynamic properties in addition to static properties. The purpose of using these criteria is to diminish the search region of optimization algorithms and as a consequence, reduce the computational time and cost of optimization, which are the main challenges in well placement optimization problems. However, considering the significant subsurface uncertainty, a probabilistic definition of ROI (SROI) or DM (SDM) is needed, since there exists an infinite number of possible distribution maps of static and/or dynamic properties. To build SROI or SDM maps, the k-means clustering technique is used to extract a limited number of characteristic realizations that can reasonably span the uncertainties. In addition, to determine the optimum number of clustered realizations, Higher-Order Singular Value Decomposition (HOSVD) method is applied which can also compress the data for large models in a lower-dimensional space. Additionally, we introduce the multiscale spatial density of ROI or DM (D2ROI and D2DM), which can distinguish between regions of high SROI (or SDM) in arbitrary neighborhood windows from the local SROI (or SDM) maxima with low values in the vicinity. Generally, we develop and implement a new systematic approach for well placement optimization for both green and brownfields on a synthetic reservoir model. This approach relies on the utilization of multi-scale maps of SROI and SDM to improve the initial guess for optimization algorithm. Narrowing down the search region for optimization algorithm can substantially speed up the convergence and hence the computational cost would be reduced by a factor of 4.

    • 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 market integration, efficiency orientation, and drivers of foreign subsidiary divestments

      Belderbos, René; De Michiel, Federico; Sleuwaegen, Leo; Wu, Shubin (Journal of World Business, 2021)
      Differences in global market integration across industries have important repercussions for MNC strategy and the drivers of manufacturing subsidiary divestment decisions. Global industry integration and the associated competitive pressures lead MNCs to adopt cost efficiency strategies for their subsidiary networks, and subsidiary divestment decisions are strongly driven by labor cost considerations. In non-integrated industries, host country demand conditions are the prime driver of divestments. These patterns are the most salient for MNCs that have aligned their strategy with the global industry environment. Analysis of the divestment hazards of 3827 Japanese manufacturing subsidiaries in 57 countries provides support for these conjectures.
    • 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.
    • Global vs. low carbon economy: The case of the revised EU emissions trading scheme

      Ahner, Nicole; Meeus, Leonardo (Review of European Community and International Environmental Law, 2010)
      Europe is tightening its climate change policy and with that its pollution control legislation, supposedly to lead the way towards a low carbon economy. As the rest of the world is lagging behind in greenhouse gas emission reduction efforts, this causes increasing concern for the European carbon‐intensive industry. In order to address concerns of economic competitiveness and emission leakage, the EU is considering the extension of its recently revised EU Emission Trading Scheme on carbon‐intensive goods imported from countries not taking comparable action to reduce their emissions. This article examines the permissibility of such an extension under the law of the World Trade Organization, namely the General Agreement of Tariffs and Trade (1994).
