    • Nearest neighbour propensity score matching and bootstrapping for estimating binary patient response in oncology: A Monte Carlo simulation

      Geldof, Tine; Dusan, Popovic; Van Damme, Nancy; Huys, Isabelle; Van Dyck, Walter (Scientific Reports: A Nature Research Journal, 2020)
      Nearest Neighbour (NN) propensity score (PS) matching methods are commonly used in pharmacoepidemiology to estimate treatment response using observational data. Unfortunately, there is limited evidence on the optimal approach for accurately estimating binary treatment response and, more so, to estimate its variance. Bootstrapping, although commonly used to accurately estimate variance, is rarely used together with PS matching. In this Monte Carlo simulation-based study, we examined the performance of bootstrapping used in conjunction with PS matching, as opposed to diferent NN matching techniques, on a simulated dataset exhibiting varying levels of real world complexity. Thus, an experimental design was set up that independently varied the proportion of patients treated, the proportion of outcomes censored and the amount of PS matches used. Simulation results were externally validated on a real observational dataset obtained from the Belgian Cancer Registry. We found all investigated PS methods to be stable and concordant, with k-NN matching to be optimally dealing with the censoring problem, typically present in chronic cancer-related datasets, whilst being the least computationally expensive. In contrast, bootstrapping used in conjunction with PS matching, being the most computationally expensive, only showed superior results in small patient populations with long-term largely unobserved treatment efects.

    • Negatieve feedback leidt zelden tot verbetering

      Van Steerthem, Angie (HR Magazine, 2019)
      Kritische beoordelingen van collega's zetten medewerkers ertoe aan hun rol aan te passen, zodat ze meer kunnen samenwerken met wie hen positievere beoordelingen geeft. Hoe negatiever de feedback, hoe verder de werknemers gaan om nieuwe netwerken te smeden. Dat blijkt uit onderzoek van Paul Green, doctoraatsstudent aan de Harvard Business School en twee van zijn collega’s. Het onderzoek werd onder meer gevoerd in een bedrijf dat een transparant peerreviewproces hanteert en de medewerkers toelaat hun job voor een stuk zelf vorm te geven.

    • Networks in professional groups: a matter of connection or self-excile?

      Boros, Smaranda; Van Gorp, Lore (Team Performance Management: An International Journal, 2017)
      Purpose - Integrating predictions of social exchange theory and implicit social cognition, this paper aims to investigate mechanisms of co-evolution between professional and personal support networks in a professional, non-hierarchical setting. Design/methodology/approach - The study covers simultaneously people's behaviours and their subjective interpretations of them in a cross-lagged network design in a group of 65 MBAstudents. Findings - Results show that people build on their professional support network to develop personal support relations. People who have a high status in the professional support network appear to be afraid to lose them by asking too many others for personal support and people with a low status in the professional support network seemalso be reluctant to ask many others for personal support. Practical implications - Although personal support is a key social mechanism facilitating individual well-being and organizational success, support in the workplace often remains limited to professional topics. This research shows why people hesitate to expand their networks in professional settings and to what extent their fears have a basis in reality. Originality/value - It goes beyond predictions of social exchange theory which inform most network evolution studies and tap into implicit social cognition predictions to expand the explanatory power of the hypotheses. The study's network analysis takes into account both behaviours and social perceptions. The sample is a non-hierarchical professional group which allows a more ecological observation of how hierarchies are born in social groups.
    • A new algorithm for resource-constrained project scheduling with breadth and depth of skills

      Snauwaert, Jakob; Vanhouke, Mario (European Journal of Operational Research, 2021)
      This paper addresses a multi-skilled extension of the resource-constrained project scheduling problem (RCPSP). Although a handful of papers dealt with the multi-skilled RCPSP (MSRCPSP), little to no attention is given to the ideal levels of skills for multi-skilled resources. In this paper, skills are measured along two dimensions known as breadth and depth. In a project environment, the breadth of a resource is perceived as the amount of skills an employee masters. The depth of a skill is the efficiency level at which work can be performed by a resource that masters that skill. The MSRCPSP with breadth and depth consists of scheduling activities with skill requirements and assigning multi-skilled resources to those activities. To be able to efficiently solve the MSRCPSP, a genetic algorithm is developed. Using the created activity schedules and resources assignments, the best workforce characteristics are analysed. Key aspects in this analysis are the breadth and depth. The problem-specific procedure combines a new representation, a new crossover and tailor-made local searches. Computational experiments measure the impact of different multi-skilled resources and their efficiency levels on the makespan of the project.

    • New computational results on the discrete time/cost trade-off problem in project networks

      Demeulemeester, Erik; De Reyck, B.; Foubert, Bram; Herroelen, Willy; Vanhoucke, Mario (Journal of the Operational Research Society, 1998)
      A description is given of a new exact procedure for the discrete time/cost trade-off problem in deterministic activity-on-the-arc networks of the CPM type, where the duration of each activity is a discrete, nonincreasing function of the amount of a single resource (money) committed to it. The objective is to construct the complete and efficient time/cost profile over the set of feasible project durations. The procedure uses a horizon-varying approach based on the iterative optimal solution of the problem of minimizing the sum of the resource use over all activities subject to the activity precedence constraints and a project deadline. The optimal solution is derived using a branch-and-bound procedure.
    • New directions in entrepreneurial finance

      Cumming, Douglas; Deloof, Marc; Manigart, Sophie; Wright, Mike (Journal of Banking and Finance, 2019)
      Entrepreneurial finance is a distinctive aspect of corporate finance, notably with respect to informational asymmetries and investor involvement in portfolio companies. Entrepreneurial finance research has explored four levels of analysis: the entrepreneur or entrepreneurial firm, the organization providing finance to the entrepreneurs, the organizations providing funds to these organizations, and the region or country in which the entrepreneurial firms or investors are established. We discuss recent developments in forms of entrepreneurial finance. We summarize the contributions of the papers published in this issue on entrepreneurial finance at different points in the life cycle, including work on trade credit, debt finance, micro-cap IPOs, venture capital, and angel finance. Also, we highlight avenues for future research focusing on funding gaps, accelerators, crowdfunding, secondary buyouts, boards, and exits.
