    • Investigating synchromodality from a supply chain perspective

      Chuanwen, Dong; Boute, Robert; McKinnon, Alan; Verelst, Marc (Elsevier, 2018)
      Greater use of multimodal transportation can substantially improve the environmental performance of freight transportation. Despite strenuous efforts by public policy-makers to alter the freight modal split, most companies still rely heavily on road transportation, and modal shifts to rail and water have remained modest at best. In this paper we argue that this is partly the result of a failure to take a holistic supply chain view of the modal shift process. Synchromodality provides a framework within which shippers can manage their supply chains more flexibly to increase the potential for shifting mode. On the basis of a literature review, we broaden the conventional focus of multimodal transportation to give it a supply chain dimension, and propose the concept of ‘Synchromodality from a Supply Chain Perspective' (SSCP). Using a case study we show that when the supply chain impacts are taken into account, it is possible to significantly increase the share of intermodal rail transportation within a corridor, without necessarily increasing total logistics cost or reducing the service level. In this way the environmental impact of freight activities can be significantly reduced.
    • Investigating the added value of integrating human judgement into statistical demand forecasting systems

      Baecke, Philippe; De Baets, Shari; Vanderheyden, Karlien (Elsevier, 2017)
      Whilst the research literature points towards the benefits of a statistical approach, business practice continues in many cases to rely on judgmental approaches for demand forecasting. In today's dynamic environment, it is especially relevant to consider a combination of both approaches. However, the question remains as to how this combination should occur. This study compares two different ways of combining statistical and judgmental forecasting, employing real-life data from an international publishing company that produces weekly forecasts on regular and exceptional products. Two forecasting methodologies that are able to include human judgment are compared. In a 'restrictive judgement' model, expert predictions are incorporated as restrictions on the forecasting model. In an 'integrative judgment' model, this information is taken into account as a predictive variable in the demand forecasting process. The proposed models are compared on error metrics and analysed with regard to the properties of the adjustments (direction, size) and of the forecast itself (volatility, periodicity). The integrative approach has a positive effect on accuracy in all scenarios. However, in those cases where the restrictive approach proved to be beneficial, the integrative approach limited these beneficial effects. The study links with demand planning by using the forecasts as input for an optimization model to determine the ideal number of SKUs per Point of Sale (PoS), making a distinction between SKU forecasts and SKU per PoS forecasts. Importantly, this enables performance to be expressed as a measure of profitability, which proves to be higher for the integrative approach than for the restrictive approach.
    • Investigating the meaning of supplier‐manufacturer partnerships: An exploratory study

      Lemke, Fred; Goffin, Keith; Szwejczewski, Marek (Emerald, 2003)
      Supplier partnerships can be the key in enhancing the performance of manufacturing companies. Consequently, partnership has been strongly recommended by academics and practitioners alike. Surprisingly, the concept of partnership is only poorly understood. Many authors have identified the advantages that it can bring but far less has been published on the attributes of partnership itself. What is known is that partnerships are “close” relationships and thus, the level of relationship closeness is an appropriate angle for exploring supplier partnerships. Research was conducted using the repertory grid technique with an exploratory sample of ten managers from four German engineering companies. It revealed that supplier partnerships are very different from other forms of relationship and identified five distinct attributes of partnerships. These findings have a number of implications for both practitioners and researchers.

    • IP Models to orchestrate innovation ecosystems: IMEC, a public research institute in nano-electronics

      Leten, Bart; Vanhaverbeke, Wim; Roijakkers, Nadine; Clerix, André; Van Helleputte, J. (2013)
      Companies increasingly organize innovation activities within innovation ecosystems. This study illustrates the central role of the IP-model that an orchestrator develops for the innovation ecosystem partners. The governance of IP is instrumental for the success of innovation ecosystems as it determines the value appropriation potential for the ecosystem partners and positively influences the success of innovation ecosystems. The insights are based on a case study of IMEC, a public research institute in nano-electronics. IMEC has an IP-based orchestration model for innovation ecosystems through multi-party research collaborations between public and private firms.

    • Is advertising for losers? An empirical study from a value creation and value capturing perspective

      Tackx, Koen; Rothenberger, Sandra; Verdin, Paul (2017)
      Does advertising lead to higher profits? This question has preoccupied company executives and academic researchers for many decades. Arguments have been put forth in both directions, and evidence is mixed at best. In this article, we re-examine the question from a value creation and value capturing perspective, which allows us to re-interpret and reconcile the different views and empirically validate the resulting hypotheses. Using a database of the top 500 brands of established companies during the 2008-2015 period, we find that advertising spending has no significant impact on profitability, while both brand value and research and development (R&D) spending have a clearly positive effect. In addition, we observe a positive interaction effect between advertising spending and R&D spending and a negative interaction between brand value and R&D spending on profitability. These findings corroborate the view that advertising in and of itself does not improve profitability, rather, its effect is positive only when it acts in support of customer value creation as a result of R&D.

    • Is Gender Stereotyping More Prevalent in Masculine Countries? A Cross-National Analysis

      Odekerken-Schröder, Gaby; De Wulf, Kristof; Hofstee, Natascha (2002)
      The objective of this study is to test whether gender stereotyping in printed advertising is more prevalent in masculine as opposed to feminine countries. This is considered important, as advertising is generally more influential than literature in spreading stereotypical ideas, given its high accessibility. Moreover, the way in which sexes are portrayed in advertising affects people's perceptions of gender roles in real life. Using content analysis, we collected empirical data on gender stereotyping of women depicted in 946 printed advertisements from two European countries widely differing in their level of masculinity - the UK and the Netherlands. The results indicate that a country's masculinity index is hardly related to the use of gender stereotyping in printed advertising, potentially implying that other factors underlie the use of gender stereotyping.
    • Is it here where I belong? An integrative model of turnover intentions

      Boros, Smaranda; Curseu, Petru L . (2013)
      We test a mediated moderation model in which the influence of organizational prestige and permeability on turnover intentions is mediated by organizational commitment and identification. We test this model in a 2 × 2 design in four Romanian organizations. Results support a partial mediation of identification between the considered organizational antecedents, and their interaction upon affective and continuance commitment, and a full mediation of commitment between identification and turnover intentions. Permeability moderates the impact of prestige upon identification and commitment. Finally, we draw conclusions about the mind‐sets behind identification, affective, and continuance commitment, and propose implications for future research and practitioners.

    • It's only temporary. Time frame and the dynamics of creative project teams

      Bakker, René M.; Boros, Smaranda; Kenis, Patrick; Oerlemans, Leon (2013)
      The success of many knowledge‐intensive industries depends on creative projects that lie at the heart of their logic of production. The temporality of such projects, however, is an issue that is insufficiently understood. To address this, we study the perceived time frame of teams that work on creative projects and its effects on project dynamics. An experiment with 267 managers assigned to creative project teams with varying time frames demonstrates that, compared to creative project teams with a relatively longer time frame, project teams with a shorter time frame focus more on the immediate present, are less immersed in their task and utilize a more heuristic mode of information processing. Furthermore, we find that time frame moderates the negative effect of team conflict on team cohesion. These results are consistent with our theory that the temporary nature of creative projects shapes different time frames among project participants, and that it is this time frame that is an important predictor of task and team processes.
    • It’s the end of the competition: When social comparison Is not always motivating for goal achievement (Published Online)

      Chan, Elaine; Briers, Barbara (JCR, 2018)
      Nowadays consumers can easily connect with others who are pursuing similar goals via smart devices and mobile apps. This technology also enables them to compare how well they are doing relative to others in a variety of contexts, ranging from online gaming to losing weight to loyalty programs. This research investigates consumers’ motivation to achieve a goal when they compare themselves with a superior other who has already attained the goal. Building on the literature on social comparison, and on competition in particular, we find that consumers are less motivated when the superior other has attained the goal compared to when the superior other is just ahead, keeping the relative distance equal. This negative effect on motivation is evident even in situations in which consumers can still attain the same goal as the superior other. We argue and demonstrate that this effect occurs because the other’s goal attainment limits consumers’ prospect to compete and overtake the superior other. Six experimental studies show evidence for this effect in hypothetical loyalty programs and behavioral task completion. These findings provide a deeper understanding of the motivational effect of social comparison, which have implications for marketing managers and public policy makers.
