  1. De recente financi??le crisis en de dividendpolitiek van Belgische beursgenoteerde bedrijven

    Vandemaele, Sigrid; Kenis, Georges
    Deze paper bestudeert (de wijziging in) de dividendpolitiek van Belgische beursgenoteerde bedrijven tijdens de recente financi??le crisis. De resultaten wijzen erop dat beursgenoteerde bedrijven minder afkerig staan ten opzichte van dividendverlagingen tijdens de crisis dan in de jaren voor de crisis. De externe aanbodschok op de kredietmarkt leidt ertoe dat beursgenoteerde bedrijven naar het middel van dividendverlaging grijpen teneinde te verhinderen dat (interne) middelen wegvloeien uit de onderneming. Toch geven de resultaten aan dat niet alle bedrijven (in dezelfde mate) een dividendverlaging als een mogelijk optie beschouwen tijdens de financi??le crisis. De resultaten wijzen erop dat de kans op dividendverlaging tijdens de financi??le...

  2. Road safety performance evaluation and policy making by data envelopment analysis: A case study of provincial data in Iran

    Behnood, H. R.; Ayati, E.; Hermans, Elke; Neghab, M. A. Pirayesh
    Considering the need to invest in road safety programs, an efficiency analysis on implemented countermeasures is required. The system presented in this study is designed to evaluate the efficiency related to measures annually implemented throughout 30 provinces of Iran, specifically in 2008 and 2009. The model calculates a relative inefficiency index for each province and in each year, using the Data Envelopment Analysis (DEA) method. Each province in each year is defined as a Decision Making Unit (DMU) in DEA analysis. The inefficiency index is defined as the proportion of the weighted sum of road fatality risk indices to the...

  3. Assessing The Overall Driving Performance Of Older-Drivers

    BABAEE, Seddigheh; SHEN, Yongjun; HERMANS, Elke; BRIJS, Tom; WETS, Geert; CUENEN, Ariane
    This study investigates the relative performance of older drivers at the individual level, based on specific measures of functional and driving abilities. To do so, 55 participants aged 70 years and above completed tests of an assessment battery of psychological and physical aspects as well as knowledge of road signs; moreover, they took a driving simulator test in which specific driving situations that are known to cause difficulties for older drivers were included. To evaluate the overall performance of each driver, all the above information was combined by using the concept of composite indicators, and the technique of data envelopment analysis,...

  4. Assessing individual driver’s relative performance at curve: applying Data Envelopment Analysis on simulator data

    BABAEE, Seddigheh; SHEN, Yongjun; HERMANS, Elke; WETS, Geert; BRIJS, Tom; ARIEN, Caroline
    This study investigates the performance of drivers at the individual level, at two different curves, using data from a driving simulator in order to identify the best drivers within the sample and to gain insight into the most problematic behavior of each driver. To this end, 34 participants varying in age and gender completed two particular simulator scenarios and their speed, acceleration and lateral position, were monitored at various points. The concept of composite indicators, which combines single indicators into one index score, was employed, and the technique of data envelopment analysis – an optimization model for measuring the relative...

  5. Why do firms save cash from cash flows? Evidence from firm-level estimation of cash-cash flow sensitivities

    D'ESPALLIER, Bert; HUYBRECHTS, Jolien; Schoubben, Frederiek
    We construct firm-level estimates for the cash flow sensitivity of cash (CCFS) by modelling heterogeneous slopes in reduced-form cash equations. This approach allows identifying firms with a high, low or even negative savings propensity. We find that high CCFS firms have higher income variation, suggesting cash buffering is triggered by income shocks. High CCFS firms do not suffer from financing constraints measured by a wide selection of indicators. Our results suggest that the CCFS is not an adequate indicator to capture financing constraints. Rather, a higher CCFS indicates smoothing of income fluctuations by installing a cash buffer that successfully prevents...

  6. Bayesian inference for transportation origin-destination matrices: the Poisson-inverse Gaussian and other Poisson mixtures

    PERRAKIS, Konstantinos; KARLIS, Dimitris; COOLS, Mario; JANSSENS, Davy
    Transportation origin-destination analysis is investigated through the use of Poisson mixtures by introducing covariate-based models which incorporate different transport modelling phases and also allow for direct probabilistic inference on link traffic based on Bayesian predictions. Emphasis is placed on the Poisson-inverse Gaussian model as an alternative to the commonly used Poisson-gamma and Poisson-log-normal models. We present a first full Bayesian formulation and demonstrate that the Poisson-inverse Gaussian model is particularly suited for origin-destination analysis because of its desirable marginal and hierarchical properties. In addition, the integrated nested Laplace approximation is considered as an alternative to Markov chain Monte Carlo sampling...

  7. Adapting inventory models for handling various payment structures using net present value equivalence analysis

    BEULLENS, Patrick; JANSSENS, Gerrit
    Classic inventory models use average cost functions. It is generally accepted that these models should account for the time value of money. They do so not by considering the timing of cash-flows, but by including opportunity costs. The Net Present Value (NPV) framework has long been used to compare these models with. We formalise NPV Equivalence Analysis (NPVEA) under various payment structures, and apply it to a few classic inventory models. While taking the linear approximation is typically part of the process to find equivalence, the essence is to disregard the parameters of a classic inventory model but instead start...

  8. Implementing an electronic medication overview in Belgium.

    Storms, Hannelore; Marquet, Kristel; Nelissen, Katherine; Hulshagen, Leen; Lenie, Jan; Remmen, Roy; Claes, Neree
    Background: An accurate medication overview is essential to reduce medication errors. Therefore, it is essential to keep the medication overview up-to-date and to exchange healthcare information between healthcare professionals and patients. Digitally shared information yields possibilities to improve communication. However, implementing a digitally shared medication overview is challenging. This articles describes the development process of a secured, electronic platform designed for exchanging medication information as executed in a pilot study in Belgium, called “Vitalink”. Findings: The goal of “Vitalink” is to improve the exchange of medication information between professionals working in healthcare and patients in order to achieve a more efficient...

  9. Bevindingen van zorgverleners bij de implementatie van een papieren medicatieschema.

    Storms, Hannelore; Claes, Neree; Hulshagen, Leen; Conings, Stefanie; Nelissen, Katherine
    Achtergrond Medicatiemanagement vereist een goede communicatie tussen zorgverleners intra- en transmuraal. Doelstelling In deze studie wordt nagegaan of een papieren medicatieschema de communicatie tussen zorgverleners van de eerste en tweede lijn in Zuidoost-Limburg verbetert. Methode In deze regio werd een papieren medicatieschema geïmplementeerd. Via een voor- en na-bevraging bij deelnemende zorgverleners werd het potentieel van het papieren medicatieschema nagegaan. De verwachtingen, de bevindingen en het gebruik van dit schema werden bevraagd. Resultaten Als belangrijkste valkuilen worden tijdsinvestering van zorgverleners en de medewerking van patiënten genoteerd. Een papieren medicatieschema blijkt voornamelijk te worden gebruikt om medicatiefouten te reduceren. Daarnaast zien slechts enkele zorgverleners het potentieel van een papieren medicatieschema als instrument...

  13. Workshops as a useful tool to better understand care professionals’ Views of a Lean change program

    SIMONS, Pascale; Benders, Jos; Marneffe, Wim; Pijls-Johannesma, Madelon; Vandijck, Dominique
    Purpose For change programs to succeed, it is vital to have a detailed understanding of employees’ views regarding the program, especially when the proposed changes are potentially contested. Gaining insight into employee perceptions helps managers to decide how to proceed. We conducted two workshops in a radiotherapy institute to assess the benefits and drawbacks, as well as their underlying causes, of a proposed lean change program. Managers’ views on the workshops’ usefulness were charted. Design/methodology/approach Two workshops were organized in which employees predicted positive and negative effects of a lean program. The workshops combined a structured brainstorm (KJ-technique) and an evaluation of the...

  14. The use of process mining in a business process simulation context: overview and challenges

    MARTIN, Niels; DEPAIRE, Benoit; CARIS, An
    This paper focuses on the potential of process mining to support the construction of business process simulation (BPS) models. To date, research efforts are scarce and have a rather conceptual nature. Moreover, publications fail to explicit the complex internal structure of a simulation model. The current paper outlines the general structure of a BPS model. Building on these foundations, modeling tasks for the main components of a BPS model are identified. Moreover, the potential value of process mining and the state of the art in literature are discussed. Consequently, a multitude of promising research challenges are identified. In this sense,...

  15. De niet-familiale CEO in het familiebedrijf. Hoe komen tot een succesvolle en duurzame relatie

    Hendriks, Walter; Lambrechts, Frank; Vandenrijt, Liesbeth; Kelleci, Ruveyda; Voordeckers, Wim; Huybrechts, Jolien; Dekker, Julie
    België staat voor een enorme uitdaging: 20.000 Belgische bedrijven zullen de eerstkomende jaren op zoek moeten naar een CEO opvolger. Het vinden van de juiste opvolger is voor deze bedrijven cruciaal voor het voortbestaan van de onderneming. Dit boek gaat specifiek in op het CEO opvolgingsproces in familiebedrijven. Traditiegetrouw kiezen familiebedrijven voor een opvolger uit de eigen familie. Slechts 11 procent van de familiebedrijven kiest op dit moment voor een CEO opvolger van buiten de familie. Het doel van dit boek is tweeledig. Het eerste doel is het wetenschappelijk onderbouwen van de verschillende facetten van het opvolgingsproces. Eén van de facetten...

  16. Towards inclusive careers: Reimagining, rethinking and reshaping careers from the perspective of disadvantaged groups

    VAN LAER, Koen; Verbruggen, Marijke; Janssens, Maddy
    In recent decades, we have seen the emergence of the ???new??? career discourse, describing the rise of ???new??? careers, characterized by increased career mobility driven by personal initiative and marketable skills and networks. The goal of this article is bringing the voice of disadvantaged groups in the conversations about ???new??? careers, which currently mainly seem to reflect the experiences of relatively privileged individuals on the labour market. Drawing on the literature on the careers and organizational experiences of historically disadvantaged groups, on the diversity literature, and on qualitative material about the careers of individuals from disadvantaged groups, this article explores...

  17. Serious Injuries: An Additional Indicator to Fatalities for Road Safety Benchmarking

    SHEN, Yongjun; HERMANS, Elke; BAO, Qiong; BRIJS, Tom; WETS, Geert
    Objectives: Almost all of the current road safety benchmarking studies focus entirely on fatalities, which, however, represent only one measure of the magnitude of the road safety problem. The main objective of this article was to investigate the possibility of including the number of serious injuries in addition to the number of fatalities for road safety benchmarking and to further illuminate its impact on the countries' rankings. Methods: We introduced the technique of data envelopment analysis (DEA) to the road safety domain and developed a DEA-based road safety model (DEA-RS) in this study. Moreover, we outlined different types of possible...

  18. Risk perception, attitudes towards risk and risk management: evidence and implications

    Wauters, Erwin; van Winsen, Frankwin; DE MEY, Yann; Lauwers, Ludwig
    The comprehensive risk analysis of a business such as farming entails questions on what is at stake, how important is the risk concern and how to deal with it. We performed a sequential mixed method, with the in-depth interviews in the first stage (n = 35), followed by a survey on the Flemish FADN (n = 614) in the second, to investigate the farmers' risk perception, the attitudes towards risk and the perceived usefulness of the risk management strategies. We find that, rather than the short-term volatility in prices, the longer term co-evolution of expenses versus receipts is of a...

  19. The impact of effective patents on future innovations in nanomedicine

    Bosetti, Rita; Vereeck, Lode
    The success of nanomedicine is dependent upon an effective protection of IP rights. Unfortunately, the US nanomedicine patent system is dysfunctional because long R&D procedures as well as the patent pendency are insufficiently taken into account. This could be solved by changing the patent-protection starting point and increasing the capacity of the US PTO. The nanotechnology industry also suffers from overlapping patents. This could be avoided by improving the expertise of the PTO, using a more accurate definition of nanotechnology and devising a generally accepted nomenclature that enhances prior-art searches. To avoid disputes, inference practices and strategic patenting can be...

  20. Evaluating implementation of the emergency severity index in a Belgian hospital

    BERGS, Jochen; Verelst, Sandra; Gillet, Jean-Bernard; VANDIJCK, Dominique
    Introduction: Triage aims to categorize patients based on their clinical need and the available departmental resources. To accomplish this goal, one needs to ensure that the implemented triage system is reliable and that staff use it correctly. Therefore this study assessed the ability of Belgium nurses to apply the Emergency Severity Index (ESI), version 4, to hypothetical case scenarios after an educational intervention. Methods: An ESI educational intervention was implemented in accordance with the ESI manual. Using paper case scenarios, nurses' interrater agreement was assessed by comparing triage nurse ESI levels with the reference answers noted in the implementation manual....
