  • Empty pockets full stomachs: How monetary scarcity and monetary primes lead to caloric desire

    Briers, Barbara; Laporte, Sandra (2010)
    Monetary scarcity and money primes may induce people to desire more calories. This Pavlovian association between money and food appears driven by the instrumental, secondary reinforcer value of money rather than by its primary rewarding qualities: The effect only holds for food choices but does not generalize to nonfood items and is not moderated by individual sensitivity for reward (study 1). The effect also is restricted to persons who adopt an instrumental value of money (study 2). In addition, merely priming people with money can lead to caloric desire, but this effect disappears with monetary satiation (study 3). In line with the value heuristic, people lacking money or those primed with money perceive food items as less caloric because they value calories more. Accordingly, they prefer bigger portions.
  • Patient-level effectiveness prediction modeling for glioblastoma using classification trees (Accepted)

    Geldof, Tine; Van Damme, Nancy; Huys, Isabelle; Van Dyck, Walter (Frontiers in Pharmacology, 2020)
    Little research has been done in pharmacoepidemiology on the use of machine learning for exploring medicinal treatment effectiveness in oncology. Therefore, the aim of this study was to explore the added value of machine learning methods to investigate individual treatment responses for glioblastoma patients treated with temozolomide.

  • A 2020 perspective on the building of online trust in e-business relationships (Accepted)

    Stouthuysen, Kristof (Electronic Commerce Research and Applications, 2020)
    Perhaps the most important trend we observe in an increasing digitalized landscape, is that the internet technology allows organizations and individuals to interact across the globe. More and more organizations, both start-ups and more mature ones, ranging from retail to healthcare to energy, from public to private institutions are aware about the possibilities of extending their services outside their walled offices and physical points of contacts. E-consumers also seem more satisfied with the possibility to interact and transact with organizations without the constraints of time and space.
  • From one-class to two-class classification by incorporating expert knowledge: Novelty detection in human behaviour (Published Online)

    Oosterlinck, Dries; Benoit, Dries F.; Baecke, Philippe (European Journal of Operational Research, 2019)
    One-class classification is the standard procedure for novelty detection. Novelty detection aims to identify observations that deviate from a determined normal behaviour. Only instances of one class are known, whereas so called novelties are unlabelled. Traditional novelty detection applies methods from the field of outlier detection. These standard one-class classification approaches have limited performance in many real business cases. The traditional techniques are mainly developed for industrial problems such as machine condition monitoring. When applying these to human behaviour, the performance drops significantly. This paper proposes a method that improves existing approaches by creating semi-synthetic novelties in order to have labelled data for the two classes. Expert knowledge is incorporated in the initial phase of this data generation process. The method was deployed on a real-life test case where the goal was to detect fraudulent subscriptions to a telecom family plan. This research demonstrates that the two-class expert model outperforms a one-class model on the semi-synthetic dataset. In a next step the model was validated on a real dataset. A fraud detection team of the company manually checked the top predicted novelties. The results show that incorporating expert knowledge to transform a one-class problem into a two-class problem is a valuable method.

  • Five years of the Vlerick Energy Centre. An overview of results and lessons learned

    Broeckx, Saskia; Meeus, Leonardo (2019)
    An overview of results and lessons learned from five years of the Vlerick Energy Centre. Energy concerns all of us. Being intertwined with the debate on decarbonisation and climate change, energy is a potentially hot topic. Two extreme positions have attracted significant media coverage during the past year. At one end of the spectrum are those people who feel the transition cannot happen fast enough, engaging in climate protests inspired by Greta Thunberg. At the other end are the Gilets Jaunes, applying the brakes because they believe, on the contrary, that things are moving too fast and life has become too expensive.

  • De zorgkostenstructuur kan veel scherper

    Roodhooft, Filip (Management Scope, 2019)
    Zorginstellingen kunnen bijdragen aan het tegengaan van stijgende zorgkosten. Feit is dat bijdragen vanuit overheid en verzekeraars niet veel zullen en kunnen stijgen: de grens is wat dat betreft bereikt. Filip Roodhooft van Vlerick Business School pleit voor slimme oplossingen in de zorg.
  • The risk implications of diversification: Integrating the effects of product and geographic diversification (Published Online)

    Mammen, Jan; Alessandri, Todd; Weiss, Martin (Long Range Planning, 2019)
    The risk implications of product diversification have received considerable attention from scholars. However, our understanding of the effects of geographic diversification on risk is more limited. Relying on resource-based theory to frame our arguments, we argue that despite some similarities, the two types of diversification have differing effects on firm risk. We first establish the risk reducing effects for product diversification. We then integrate the unique aspects of geographic diversification that serve as a boundary condition to the RBV perspective, arguing for the risk increasing effects of geographic diversification. Finally, since many firms pursue both forms of diversification simultaneously, we explore the joint effects of both product and geographic diversification. We test our hypotheses in a longitudinal model on a sample of S&P 500 firms. Our findings suggest that total product diversification, as well as related diversification reduce risk, while total geographic diversification increases risk. Furthermore, our data provide evidence of a complex combination of joint effects of these two forms of diversification. These findings offer a more complete understanding of the risk effects of corporate diversification.
  • Imitation of management practices In supply networks: Relational and environmental effects (Published Online)

    Reusen, Evelien; Stouthuysen, Kristof; Van den Abbeele, Alexandra; Slabbinck, Hendrik (Journal of Supply Chain Management, 2019)
    This study investigates the imitative use of management practices across a multitier supply network. Although imitation may take the form of any management practice, operationally, we focus on whether the buyer's control practices used with first‐tier suppliers results in similar control practices being used by these first‐tier suppliers with the second‐tier suppliers. Drawing on institutional theory, we identify relational context (i.e., affective commitment) and environmental context (i.e., environmental uncertainty) as two important factors influencing the extent to which such imitation takes place. Using unique survey data of vertically linked supply chain triads, we generally find support for the occurrence of imitation and more so in cases of high affective commitment. The results regarding environmental uncertainty further reveal selectivity in imitative behavior, calling attention to the level of deliberateness in imitation decisions in supply networks. Besides contributing to theory on imitative behaviors in the supply chain, this study also generates practical implications on the spread of management practices across multiple tiers.

  • Outcomes of team creativity: A person-environment fit perspective

    Bam, Louzanne; De Stobbeleir, Katleen; Vlok, PJ (Management Research Review, 2019)
    Limited research where team creativity (TC) is positioned as an independent variable constitutes a weak point in the body of knowledge. This paper aims to offer three contributions to address this research gap: empirical research that has been conducted on the outcomes of TC is summarized; a person–environment fit perspective is applied to develop a conceptual model for TC; and directions for future empirical research are proposed. A literature review is conducted to identify empirical research on the outcomes of TC. This is summarized into an extension of an existing framework that organizes empirical research on the antecedents of TC. Furthermore, the fit model for TC is developed, based on a person–environment fit perspective. Research on the outcomes of TC has focused on three themes: performance; affective state; and processes. Gaps in this body of knowledge include limited knowledge on performance outcomes and a lack of research on potential negative outcomes. Recommendations for future research include: potential moderators of the relationship between TC and two outcome, innovation and team performance, are proposed; strain and unethical decision-making are proposed as potential negative outcomes of TC; and it is proposed that incorporating a temporal dimension would improve the understanding of the cyclical manner in which certain variables and TC may interact over time. he organizing framework extension summarizes existing knowledge on the outcomes of TC, and together with the fit model for TC, this offers a basis for identifying research gaps and directions for future research. Specific directions for future empirical research are proposed.
  • Academic fashion and crowdfunding: How to explain the craze for crowdfunding as a research topic

    Le Pendeven, Benjamin; Bardon, Thibaut; Manigart, Sophie (2019)
    Since Dushnitsky and Klueter’s paper on “an e-Bay for ideas” (2011), academic research on crowdfunding as a research topic in entrepreneurial finance has witnessed an exponential growth. Currently, about 28% of all papers in entrepreneurial finance are about crowdfunding (Wattelgroth et al. 2018). The academic interest in crowdfunding as a research topic largely exceeds the economic significance of crowdfunding as a mode of financing since only a tiny fraction of new business ventures’ funding has been raised though crowdfunding worldwide. For example, equity crowdfunding represented only 1.6% of the venture capital industry (Massolution, 2016; EY 2016). Hence the question we want to investigate in our current project is “How can we explain the ‘craze’ for crowdfunding as an academic research topic in entrepreneurial finance?”
  • Are you part of the crowd? The role of socio-demographic and contextual characteristics for crowdfunding awareness

    Vaznyte, Egle; Andries, Petra; Manigart, Sophie (2019)
    Crowdfunding has become an alternative source of financing for entrepreneurial new ventures and social projects. While several studies have analysed the success factors of crowdfunding campaigns, and identifying and “tapping the right crowd” has been shown crucial in this respect, we still lack a basic understanding of the individuals who are in the crowd. This study aims to increase our understanding of the supply side of crowdfunding by focussing on individuals’ crowdfunding awareness. Integrating information processing theory with insights from financial literacy and institutional theory, and using a sample of 1,042 individuals in Flanders (Belgium), we find that individuals’ awareness of specific crowdfunding initiatives is very low. A favourable normative environment and a conducive environment increases an individual’s awareness of crowdfunding in general, and women tend to derive their crowdfunding awareness to a larger extent from these environmental characteristics than men.
  • Investment timing and the return on VC backed IPOs

    Manigart, Sophie; Mulier, Klaas; Verplancke, Frederik (2019)
    In this study we explain the returns obtained on venture capital (VC) investments in US companies that go public. Using a unique dataset of 1,921 investor-IPO returns, representing 564 IPOs, we show that later investments result in a higher return. This holds after controlling for observed and unobserved IPO company and VC investor characteristics. This is counterintuitive, as later investments should be less risky compared to early investments. We show that the positive relationship between investment timing and return can be explained by the VC’s reputation and the risk and uncertainty related to the IPO. The higher returns for late investments are obtained by high reputation VCs and on investments in more risky and uncertain IPOs. We exclude other possible explanations, such as IPO ratchets for late investors, exit pressure because of the relatively short VC fund lifespan cycle or by unexpected funding needs before IPO that expropriate early investors.
  • Examining the service engagement process in value co-creation in healthcare service delivery: A multi-level perspective

    Osei-Frimpong, K.; Wilson, A.; Lemke, Fred; Mclean, G. (2018)
    This study furthers our understanding of value co-creation, which has received little attention in the doctor-patient encounter relationship. We employed a quantitative survey method to shed light on factors driving this fundamental service aspect, followed up with a multilevel data analysis. These factors (assurance, social skills, doctor-patient orientation) from the doctor significantly strengthen the effects of the patient-level factors (trust, perceptual beliefs, interactions) on the service engagement and outcomes of the focal doctorpatient dyad. We establish the cross-level interactive effects at the group level of the focal dyad on service engagement. The findings suggest service engagement at the group level had no significant effect on patients’ perceived value. We provide new empirical insights to understand and operationalize these fundamental influencing factors of the value co-creation concept in a healthcare setting, and contribute to the value co-creation literature.
