Publication Leading successful digital transformations(Ivey, 2024) Viaene, StijnWhile a brain surgeon’s mastery of the scalpel is key to success in the operating room, it can also be an asset when doing non-medical tasks, such as preparing sashimi for dinner. But scalpel skills offer little advantage when dealing with patient stress or changing tires or diapers. In other words, the usefulness of surgical skills depends on the context in which they are deployed. And the same can be said about some leadership skills, especially in the digital age. So why is context often overlooked when organizations seek a digital transformation leader?Publication Relational construal in negotiation: Propositions and examples from Latin and Anglo cultures(Brill | Nijhoff, 2011) Ramírez-Marín, Jimena Y.; Brett, Jeanne M.; Universidad de Sevilla San Fernando 4, 41004 Seville Spain; Northwestern University, Kellogg School of Management 2001 Sheridan Road, Evanston, IL 60208 USAIn certain cultures, relationships are the reason for negotiation. In this article, we offer a rationale regarding why relationships have more or less salience across cultures. We present psychological, economic and sociological factors that explain the reasons for negotiating relationally. Propositions are made as to how cultural construal about relationships influences offers, targets and limits, negotiation strategy and, ultimately, economic and relational outcomes. Our major explanatory construct is new: cultural consensus about relationships. This construct is grounded in well developed theory of self construal and new empirical research showing the utility of measures of consensus in explaining cultural differences in behavior. With this theoretical contribution, we join the group of scholars who are advocating that more attention should be paid to negotiators’ subjective evaluations of the social and emotional consequences of negotiation.Publication La experiencia en negociación como facilitadora de los procesos de mediación.(2009) Ramírez-Marín, Jimena Y.; Medina, F.; Munduate, L.Publication Change management by negation: Exploring the power of the rejected(Kochi: School of Communication & Management Studies, 2020) Wetzel, RalfOrganisation and management science has been, ever since its inauguration, overly desperate to find the 'one best way of organising'. The basic fundament of that quest was the attempt to define an organisation positively, namely by what it is. Until today, this starting point has not proven to be successful; this way has not decided to disclose its ability to instruct the theory and practice of organisation yet. This article argues that this positive, ontological way to define organisations and its major results like change management has led Organization and Management Theory (OMT) into a rather blurry state. OMT and especially change management would become much more instructive again if it started defining its objects negatively, by what they are not. After showing the pitfalls of the positive fiction in OMT, the article presents a negative way to instruct, especially change management. This profit will be demonstrated by introducing the concept of the tetralemma.Publication When anger and happiness generate concessions: investigating counterpart’s culture and negotiation intentions(2022) Ramírez-Marín, Jimena Y.; Barragan Diaz, Adrian; Guzman, Felipe A.; Department of People, Organizations and Negotiation, IESEG School of Management, Univ. Lille, CNRS, UMR 9221 – LEM – Lille Economie Management, Lille, FranciePurpose – Drawing from the emotions as social information theory, this paper aims to investigate the differential effects of emotions in inter vs intracultural negotiations. Design/methodology/approach – The authors used one face-to-face negotiation and two experimental scenario studies to investigate the influence of emotions (anger vs happiness) and negotiation type (intercultural vs intracultural) on concession behavior. Findings – Across the three studies, the results consistently show that angry opponents from a different national culture obtain larger concessions from negotiators. A face-to-face negotiation shows that happy opponents from the same culture are able to obtain larger concessions from negotiators. Additionally, the negotiator’s intentions to compromise and yield mediate the relationship between the interaction of emotions and counterpart’s culture on concessions. Research limitations/implications – Two limitations are that the studies were conducted in a single country and that they use different types of role-playing designs. The empirical implications provide evidence of the moderating effect of the counterpart’s culture on the effect of anger on concessions. Then, providing two different mechanisms for concessions. Practical implications – The research helps global negotiators who face counterparts from different nationalities. It suggests that these negotiators should be mindful of their counterpart’s emotions in intercultural negotiation as anger seems to generate more concessions in this setting. Originality/value – The article is among the first studies to show that the combination of the counterpart’s culture and emotions has an effect on concessions in negotiation. Compromising and yielding are mediating mechanisms for this moderated effect. As opposed to previous studies that use.Publication When constituencies speak in multiple tongues: The relative persuasiveness of hawkish minorities in representative negotiation(Academic Press Inc. Elsevier Science, 2009) Steinel, Wolfgang; De Dreu, Carsten K.W.; Ouwehand, Elsje; Ramírez-Marín, Jimena Y.; Department of Social and Organizational Psychology, Leiden University, P.O. Box 9555, 2300 RB Leiden, The Netherlands; Department of Work and Organizational Psychology, University of Amsterdam, Amsterdam, The Netherlands; Department of Social Psychology at the University of Seville, Spain.Although constituencies often consist of opposing factions, we know little about the way such opposing factions influence the representative’s negotiation strategy. This study addressed this issue: Representatives negotiated as sellers on behalf of a group consisting of hawkish (competitive) and dovish (cooperative) factions. Experiments 1–3 showed that a minority of hawks was sufficient to influence the representatives to acting in a competitive way; only when all constituents unanimously advocated a cooperative strategy were representatives more conciliatory towards their negotiation partner. These tendencies did not differ as a function of the representatives’ pro-social versus pro-self value orientation, or the unanimity versus majority rule putatively used in the constituency to accept of reject the representative’s negotiated agreement. We conclude that hawkish minorities are persuasive and influential because representatives accord more weight to hawkish than to dovish messages.Publication The visual analogue scale as a child-friendly measure of the unhealthy = tasty intuition(2024) D'Hondt, Jonathan; Briers, Barbara; Department of Work, Organisation and Society, Ghent University, Henri Dunantlaan 2, 9000, Ghent, Belgium; Department of Marketing, Faculty of Business and Economics, Prinsstraat 13, B2000, Antwerp, BelgiumWorldwide, obesity is a growing concern. The implicit belief that healthiness and tastiness in food are inversely related (the Unhealthy = Tasty Intuition or UTI) decreases healthy food consumption and increases the risk of obesity. Since also childhood obesity has increased at an alarming rate and a large component of adult obesity is established during childhood, questions about children's own food beliefs and preferences are important. However, methods currently used to assess the UTI are either unvalidated Likert scales or implicit measures that are time intensive and too complex to be used for children. Two studies presented here offer an alternative measurement - the simple visual analogue scale. The findings show that this measure is more effective in predicting dietary quality in adults and the frequency of healthy food consumption in children compared to more traditional measures. This simple and effective tool could be used by academics and health practitioners alike to better understand children's food beliefs at an early age, which is a critical step when addressing the increasing obesity problem.Publication Gender and racial minorities on corporate boards: how board faultlines and CEO-minority director overlap affects firm performance(2024) Mendiratta, Esha; Tasheva, SabenaIn this article, we examine the multidimensional and multilevel nature of diversity in the context of corporate boards. Using the concept of faultlines, we argue that when gender and racial background aligns with human capital attributes of board members, faultlines may be formed with negative implications for firm performance. However, the potential negative impact of faultlines can be alleviated by overlaps in the characteristics of the CEO and minority directors. Specifically, we find that higher overlaps in tenure and personal range of functional experiences help overcome some of the disadvantages that minority directors face and moderate the relationship between board faultline strength and firm performance. Empirical tests using 14 years data on 262 firms belonging to S&P500 index largely support our theoretical ideas. Managerial Summary Boards often suffer from unhealthy team dynamics. In this article, we explore how alignment of board members' attributes may lead to potential subgroup formation within boards. Specifically, we examine how, under existing pressures to increase demographic diversity on corporate boards, alignment of human capital characteristics with gender and racial minority status may lead to the formation of board faultlines that negatively influence firm performance. Our results suggest that the CEO plays a pivotal role in overcoming negative consequences of board faultlines by utilizing shared tenure on board and common functional experiences with minority board members. Our research suggests that board selection needs to focus beyond scrutinizing individual-level human capital and instead understand alignments of directors' profiles that enable optimal board functioning.Publication Are complex pay systems hurting executive comp?(World at Work, 2024) Baeten, Xavier; Van Hove, Marthe; De Ruyck, BettinaTo measure CEO pay complexity, we have developed a CEO pay complexity score consisting of four dimensions, the number of: Pay instruments granted;Performance measures included in short- and long-term incentive systems;ESG dimensions included in incentive systems;Years that CEOs must hold their shares after vesting.; Our empirical analysis supports the idea that CEO pay in Europe has become more complex.Publication Making it easy to do hard things’: How experts help novices perceive craft as accessible(Sage Publications Inc., 2024) Dioun, Cyrus; Deeds Pamphile, Vontrese; Gorbatai, Andreea; University of Colorado Denver USA; George Washington University USACraft offers a path to enchantment and meaningful engagement with creation in an increasingly rationalized society. Yet, entering skilled domains where craft is practiced can be challenging for novices, particularly for those less familiar with these domains. While a growing body of research suggests that craft can be made more accessible through nontraditional pathways, the process whereby novices come to perceive craft as accessible remains undertheorized. We explore these ideas through the case of the makers, a diverse DIY movement that embraces all who build, modify, and invent across a variety of skilled domains. Using interview and observational data from Maker Faires – events wherein makers exhibit their projects and engage attendees in making activities – we induce a model of how experts enable novices to perceive craft as accessible. Our findings reveal how experts convey knowledge and skills using a creative craft approach, detailing how experts engage in scaffolding to facilitate novice creation, relax hierarchy, and cultivate fun and whimsy. In turn, this engenders the experience of enchanted engagement for novices who are able to experience how engaging in craft feels without the requisite skills or knowledge. Ultimately, this experience shapes and reinforces novices’ perception that craft is accessible. Our study contributes to the growing scholarship on craft in terms of alternative pathways for entering skilled domains, the role of craft in re-enchanting organizational life, and the emotional rewards of craft.Publication Navigating the path towards successful implementation of the EU HTA Regulation: key takeaways from the 2023 Spring Convention of the European Access Academy(2024) Brinkhuis, Francine; Julian, Elaine; van den Ham, Hendrika; Gianfrate, Fabrizio; Strammiello, Valentina; Berntgen, Michael; Pavlovic, Mira; Mol, Peter; Wasem, Jürgen; Van Dyck, Walter; Cardone, Antonella; Dierks, Christian; Schiel, Anja; Bernardini, Renato; Solà-Morales, Oriol; Ruof, Jörg; Goettsch, Wim; Utrecht WHO Collaborating Centre for Pharmaceutical Policy and Regulation, Division of Pharmacoepidemiology and Clinical Pharmacology, Utrecht University, Utrecht, The Netherlands; Secretariat of the European Access Academy (EAA), Hauensteinstr. 132, 4059, Basel, Switzerland; Utrecht WHO Collaborating Centre for Pharmaceutical Policy and Regulation, Division of Pharmacoepidemiology and Clinical Pharmacology, Utrecht University, Utrecht, The Netherlands; University of Ferrara, Ferrara, Italy; European Medicines Agency (EMA), Amsterdam, The Netherlands; Medicines Development and Training (MDT) Services, Paris, France; Institute for Health Care Management and Research, University of Duisburg-Essen, Essen, Germany; Cancer Patients Europe’ (CPE), Brussels, Belgium; Dierks + Company, Berlin, Germany; Norwegian Medicines Agency (NOMA), Oslo, Norway; Department of Biomedical and Biotechnological Sciences (BIOMETEC), Section of Pharmacology, University of Catania, Catania, Italy; HiTT Foundation, International University of Catalonia-UIC, Barcelona, Spain; Medical School of Hanover, Hanover, Germany; National Health Care Institute, Diemen, The NetherlandsThe European Regulation on Health Technology Assessment (EU HTA R), effective since January 2022, aims to harmonize and improve the efficiency of common HTA across Member States (MS), with a phased implementation from January 2025. At “midterms” of the preparation phase for the implementation of the Regulation our aim was to identify and prioritize tangible action points to move forward.Publication Design principles for a blockchain-based multi-sided platform for the sustainable trade of water: An affordance approach(Elsevier, 2024) Buyssens, Hanna; Viaene, Stijn; Research Centre for Management Informatics, KU Leuven, Leuven, BelgiumWater scarcity has become a critical challenge affecting the well-being of many communities worldwide and has been incorporated as one of the focal points within the Sustainable Development Goals (SDG 6). Digital technologies, such as blockchain technology, have shown promising potential to help tackle this issue through smart distribution of water abundancies to water-scarce regions. This research employs affordance theory and affordance-based design (ABD) to investigate the design of blockchain or distributed ledger technology (DLT) to tackle challenges related to water scarcity. Using design science research (DSR), this paper proposes design principles (DP) for a blockchain-based multi-sided platform (MSP) for the smart distribution and trade of water. To obtain our principles, we collaborated with a company employing a blockchain-based MSP for water trade. We identified the different elements of the DPs, including affordances and material properties, and matched these principles with meta-requirements obtained from the literature. This research aims to contribute to the scholarly debate by generating prescriptive knowledge in the form of DPs and providing tangible contributions that shed light on the optimal design of similar blockchain applications. These applications are envisioned to ensure their efficacy in addressing the pressing challenges of water scarcity and equitable water access, thereby fostering a sustainable and resilient future for everyone.Publication Supervised learning for integrated forecasting and inventory control(Elsevier, 2024) van der Haar, Joost F.; Wellens, Arnoud P.; Boute, Robert; Basten, Rob J.I.; Research Center for Operations Management, KU Leuven, Naamsestraat 69, Box 3555, Leuven 3000, Belgium; Flanders Make @KU Leuven, Gaston Geenslaan 8, 3001 Leuven, Belgium; School of Industrial Engineering, Eindhoven University of Technology, P.O. Box 513, 5600 MB Eindhoven, The NetherlandsWe explore the use of supervised learning with custom loss functions for multi-period inventory control with feature-driven demand. This method directly considers feature information such as promotions and trends to make periodic order decisions, does not require distributional assumptions on demand, and is sample efficient. The application of supervised learning in inventory control has thus far been limited to problems for which the optimal policy structure is known and takes the form of a simple decision rule, such as the newsvendor problem. We present an approximation approach to expand its use to inventory problems where the optimal policy structure is unknown. We test our approach on lost sales, perishable goods, and dual-sourcing inventory problems. It performs on par with state-of-the-art heuristics under stationary demand. It outperforms them for non-stationary perishable goods settings where demand is driven by features, and for non-stationary lost sales and dual-sourcing settings where demand is smooth and feature-driven.Publication Team informational resources, information elaboration, and team innovation: Diversity mindset moderating functional diversity and boundary spanning scouting effects(Wiley, 2024) van Knippenberg, Daan; Li, Jia; Tu, Yidong; Jones Graduate School of Business, Rice University, Houston, Texas, USA; Economics and Management School, Wuhan University, Luojia Hill, Wuhan, ChinaThe knowledge integration perspective on team innovation holds that information elaboration – the exchange, discussion, and integration of task-relevant information and perspectives – is the core team process driving team innovation. Factors reflecting the informational resources the team can draw on through information elaboration therefore are important influences on team innovation. In this respect, team innovation research points to team functional diversity and to team boundary spanning scouting to acquire information from outside the team. Team innovation research also makes clear that informational resources (as reflected in functional diversity and boundary spanning scouting) do not guarantee team information elaboration, and that identifying moderation in this relationship is particularly valuable. Building on this state of the science, we focus on the moderating role of the team diversity mindset – members' shared understanding of the importance of information elaboration for team performance – in the relationships of team functional diversity and boundary spanning scouting with information elaboration and team innovation. A multi-wave and multi-source survey of N = 215 teams involved in knowledge work in various Chinese organizations supported our research model for team boundary spanning scouting but not for team functional diversity.Publication Fifty years of maintenance optimization: Reflections and perspectives(Elsevier, 2024) Arts, Joachim; Boute, Robert; Loeys, Stijn; van Staden, Heletjé E.; Luxembourg Centre for Logistics and Supply Chain Management, University of Luxembourg, Luxembourg; Faculty of Economics and Business, KU Leuven, Belgium; Flanders Make@KU Leuven, Belgium; Michael Smurfit Graduate Business School, University College Dublin, IrelandOn the occasion of the 50th anniversary of the Association of European Operational Research Societies (EURO), we share our perspectives and reflections on maintenance research. We review the main methods and techniques for optimizing when and what to maintain, providing concrete examples as illustrations. We also discuss the optimization of the logistics support system surrounding the act of maintenance. In doing so, we highlight the multidisciplinary nature of maintenance research and its interface with other domains, such as spare parts inventory management, production scheduling, and transportation planning. We support our reflections with basic text-mining analyses of the archive of the European Journal of Operational Research, the journal published in collaboration with EURO. With this paper, we introduce interested researchers to maintenance optimization and share opportunities to close the gaps between the current state of research and real-world needs.Publication Project management and scheduling 2022(2024) Servranckx, Tom; Coelho, José; Vanhoucke, Mario; Faculty of Economics and Business Administration, Ghent University, Tweekerkenstraat 2, 9000, Gent, Belgium; INESC TEC, Rua Dr. Roberto Frias, 4200 - 465, Porto, Portugal Universidade Aberta, Rua da Escola Politécnica 141, 1250 - 100, Lisbon, Portugal; UCL School of Management, University College London, 1 Canada Square, E14 5AA, London, UKThis article summarises the research studies published in the special issue on Project Management and Scheduling devoted to the 18th International Conference on Project Management and Scheduling (PMS). The special issue contains state-of-the art research in the field of (non-)robust project and machine scheduling and the contribution of each individual study to the academic literature are discussed. We notice that there is a growing interest in the research community to investigate robust scheduling approaches and optimisation problems observed in real-life business settings. This allows us to derive some interesting future research directions for the project and machine scheduling community.Publication An improved algorithm for cleaning ultrahigh frequency data(Palgrave Macmillan Cham, 2010) Verousis, Thanos; Ap Gwilym, Owain; School of Business & Economics, Swansea University, Singleton Park, SA2 8PP, Swansea, UKWe develop a multiple-stage algorithm for detecting outliers in Ultra High-Frequency financial market data. We show that an efficient data filter needs to address four effects: the minimum tick size, the price level, the volatility of prices and the distribution of returns. We argue that previous studies tend to address only the distribution of returns, and may tend to ‘overscrub’ a data set. In this study, we address these issues in the market microstructure element of the algorithm. In the statistical element, we implement the robust median absolute deviation method to take into account the statistical properties of financial time series. The data filter is then tested against previous data-cleaning techniques and validated using a rich individual equity options transactions data set from the London International Financial Futures and Options Exchange. The paper has many relevant insights for any practitioner who uses high frequency derivatives data, for example, for market analysis or for developing trading strategies.Publication Price clustering and underpricing in the IPO aftermarket(Elsevier, 2010) Ap Gwilym, Owain; Verousis, Thanos; Bangor Business School, Bangor University, Gwynedd, LL57 2DG, United Kingdom; School of Business & Economics, Swansea University, Swansea, SA2 8PP, United KingdomThis is the first paper to systematically investigate price clustering in new equity assets using a high frequency transactions dataset. We test the hypotheses that past price information and market maker activities are related to price clustering. We report that price clustering in IPOs is substantially greater than the clustering observed for non-IPO assets, which supports the hypothesis that the decision of going public is followed by haziness about the true price. Underpricing is a significant determinant of price clustering for order-book trades, which supports the notion that underpriced IPOs partially reflect price uncertainties. Tick size specifications can be restrictive for individual investors, while giving execution priority to market makers. The characteristics of price clustering for off-book trades differ substantially to price clustering in the order-book.Publication Price clustering in individual equity options: Moneyness, maturity and price level(Wiley, 2013) Ap Gwilym, Owain; Verousis, Thanos; Bangor Business School, Bangor University, Bangor, United KingdomEquity options have a significant influence on the price discovery process. This study presents unique evidence of substantial price clustering in individual equity options contracts. A particular contribution arises from investigating competing hypotheses on the roles of moneyness and maturity as determinants of option price clustering. We assert that options price clustering can be decomposed to price level, moneyness, and maturity effects. After controlling for other factors, price clustering has an inverse relation with time-to-maturity. This supports the negotiation hypothesis, but not the price resolution hypothesis. Price clustering also tends to be inversely related to moneyness. This effect is linked to the intrinsic value component of option price. Both the maturity and moneyness effects act in an opposite direction to what would be anticipated on the basis of price level alone; hence, these two effects are identified as additional influences on option price clustering. It is also found that the designated market maker scheme at NYSE Euronext London International Financial Futures Exchange (LIFFE) has little influence on trade price clustering.Publication Trade size clustering and the cost of trading at the London Stock Exchange(ScienceDirect, 2013) Verousis, Thanos; Ap Gwilym, Owain; Bangor Business School, Bangor University, Bangor, LL57 2DG, UKFor the London Stock Exchange, this paper investigates differences in trading costs between market maker (off-book) and order book trades, in the context of clustering in trade sizes and prices. We report several substantial findings. Even after controlling for differences in trade size, the realised spread measure is lower for off-book trades. For the order book, trade size clustering is not associated with differences in transaction costs nor with differences in the information content of trades. For the off-book market, trades in clustered (popular) sizes carry significantly more information than non-clustered trades. Despite the significant differences in the price impact estimates between the order book and off-book, we show that traders placing large orders off-book are still better off than trading via the order book as they benefit from a large discount from the current midpoint price. Additionally, we highlight that price and size clustering tend to occur simultaneously rather than being substitutes in this market setting.
