Abstract: The maritime and port sector is widely considered conservative concerning the ability to introduce innovation in respect to other industries. This may be due to the lack of cooperative interactions among the several players involved. It does not mean that innovation does not occur in this industry. Along with some technical innovations, managerial, organizational, and cultural innovations also take place in the sector. The literature has considered the assessment and effects of the adoption of particular innovation, but still few studies underline the innovation path in a broad sense with a specific focus on terminal operators. The present article aims at filling this gap through a field analysis grouping together case studies developed in different world regions and examining the adoption path of innovation through a mix of three different techniques (i.e. the H- and I-indexes, a Systems of Innovation Analysis, and a Qualitative Comparative Analysis). Research outcomes underline how, even if no unique recipe for success can be found, specific factors (e.g. a ranking of innovation objectives, coordination among actors, and institutions) can influence the achievement of success. The analyses allow suggesting strategic and policy advice that may help link in a better way the innovation drivers with their actual effects.

Abstract: Despite the proliferation of research on ethical leadership, there remains a limited understanding of how specifically the assumingly moral component of this leadership style affects employee behavior. Taking an identity perspective, we integrate the ethical leadership literature with research on the dynamics of the moral self-concept to posit that ethical leadership will foster a sense of moral identity among employees, which then inspires followers to adopt more ethical actions, such as increased organization citizenship behavior (OCB). We further argue that these identity effects should be more pronounced when leaders are perceived to be group prototypical, as their actions then speak louder to followers’ sense of identity. Two studies—a scenario experiment with 138 participants and a field study with 225 employees—provided support for our hypothesized moderated mediation model. Perceived ethical leadership positively affected OCB via followers’ moral identity but only under conditions of high perceived leader group prototypicality. We discuss how the identity pathway of ethical leadership can facilitate novel theorizing about moral transference. Our findings also suggest that, when hiring external ethical leaders or training internal managers, practitioners are well advised to consider that these individuals may only be effective in morally transforming followers when they are perceived as prototypical for the group.

Abstract: While many disciplines embrace the possibilities that Big Data present for advancing scholarship and practice, organizational and management research has yet to realize Big Data’s potential. In an effort to chart this newfound territory, we briefly describe the principal drivers and key characteristics of Big Data. We then review a broad range of opportunities and risks that are related to the Big Data paradigm, the data itself, and the associated analytical methods. For each, we provide research ideas and recommendations on how to embrace the potentials or address the concerns. Our assessment shows that Big Data, as a paradigm, can be a double- edged sword, capable of significantly advancing our field but also causing backlash if not utilized properly. Our review seeks to inform individual research practices as well as a broader policy agenda in order to advance organizational and management research as a scientifically rigorous and professionally relevant field.

Abstract: In a panel survey of brokerage clients in the United Kingdom, participants mostly perceive their own portfolio as no more volatile than the market portfolio. Taking into account observed portfolio betas, this implies a belief in very low idiosyncratic portfolio volatility, which is even negative for a considerable fraction of the studied investor population. Possible explanations are extreme overconfidence in combination with a misunderstanding of how market and portfolio volatility are related. The identified bias contributes to underdiversification, as a belief in negative idiosyncratic volatility conceals the true benefits of diversification. In an experiment, we confirm the existence of a belief in negative volatility and rule out the underestimation of beta as an alternative explanation.

Abstract: We investigate how respectful leadership can help overcome the challenges for follower performance that female leaders face when working (especially with male) followers. Firstly, based on role congruity theory (Eagly & Karau, 2002), we illustrate the biases faced by female leaders. Secondly, based on research on gender (dis-)similarity, we propose that these biases should be particularly pronounced when working with a male follower. Finally, we propose that respectful leadership is most conducive to performance in female leader/male follower dyads compared to all other gender configurations. A multi-source field study (N = 214) provides partial support for our hypothesis. While our hypothesized effect was confirmed, respectful leadership seems to be generally effective for female leaders irrespective of follower gender, thus lending greater support in this context to the arguments of role congruity rather than gender dissimilarity.

Abstract: Ethical leadership has so far mainly been featured in the organizational behavior domain and, as such, treated as an intra-organizational phenomenon. The present study seeks to highlight the relevance of ethical leadership for extra-organizational phenomena by combining the organizational behavior perspective on ethical leadership with a classical marketing approach. In particular, we demonstrate that customers may use perceived ethical leadership cues as additional reference points when forming purchasing intentions. In two experimental studies (N = 601 and N = 336), we find that ethical leadership positively affects purchasing intentions because of customers’ concerns for moral self-congruence. We show this by means of both mediation and moderation analyses. Interestingly, the effect of perceived ethical leadership on purchasing intentions holds over and above the ethical advertising claims (e.g., cause-related marketing) that are commonly used in marketing. We conclude by discussing the possible ramifications of ethical leadership beyond its effects on immediate employees.

Abstract: Many humanitarian aid workers receive training prior to being dispatched into the field, but they often encounter challenges that require additional learning and creativity. Consequently, aid organizations formally support collaboration among the expatriate and local workers in a field office. At best, those aid workers would not only exploit their joint knowledge but also explore novel ways of managing the challenges at hand. Yet differences between expatriate and local groups (e.g., in ethnicity, religion, education, and salary) often thwart intergroup collaboration in field offices and, by extension, any joint learning or creativity. In response to this issue, we study the role of field office leaders—specifically, how their boundary-spanning behavior may inspire collaboration between the two groups and therefore facilitate joint learning and creativity. We propose that a leader's in-group prototypicality additionally catalyzes this process—that is, a leader's behavior has more impact if s/he is seen as representing his/her group. We tested and found support for our hypothesized moderated mediation model in a field sample of 137 aid workers from 59 humanitarian organizations. Thus, our study generally highlights the pivotal role that field office leaders play for crucial outcomes in humanitarian aid operations. Furthermore, we offer concrete steps for field office leaders who want to inspire better collaboration between the expatriate and local aid workers they lead.

Abstract: The humanitarian caseload is growing rapidly while funds are declining. The sector clearly will have to do more with less. Optimizing constrained resources is the strength of OR. Our discipline can strongly support humanitarian practitioners provided it works on pressing real problems and translates its research into easily implementable tools whose effectiveness can be verified. This Special Issue gathers a very rich and varied collection of papers along those principles. It clearly shows the value of OR and the many exciting research problems in this important area of humanitarian operations.

Abstract: Abstract Innovation occurs when knowledge about unmet customer needs intersects with knowledge about technological solutions. Both knowledge types are often located outside the firm and need to be absorbed in order for innovation to occur. While there has been extensive research into absorptive capacity for solution knowledge, a necessary complement − absorptive capacity for new customer needs − has been neglected. In an individual-level study of 864 employees from a home appliance firm, we show that need absorptive capacity is theoretically and empirically distinct from solution absorptive capacity, and that both are positively associated with employee innovativeness. Interestingly, we find asymmetric extra-domain effects: prior solution knowledge is positively related to need absorptive capacity (cross-pollination effect), while prior need knowledge is negatively related to solution absorptive capacity (attenuation effect). We contrast the cognitive underpinnings of the two absorptive capacity types, contributing to emerging scholarly thinking on the domain-specificity and micro foundations of absorptive capacity.

Abstract: Today, climate change is the greatest challenge for future generations. In particular, logistics is perceived as a key sector to contribute to sustainable development meeting the future generations’ needs in terms of low greenhouse gas emissions in a socially and economically responsible way. Green logistics involves all attempts to reduce the ecological impact of peoples’ mobility, traffic systems and of transport in regional and global supply chains including the reverse flow of products and materials.The primary objective of this special issue is to reflect the sustainable development of logistics from various perspectives preferably in an integrated and holistic approach and to examine research issues concerned with quantitative analysis and decision support for supply network design, freight transport and logistics infrastructure. For this special issue eight papers from 36 submissions have been selected for publication after a thorough peer-review according to the standards of the FSM journal.

Abstract: The paper introduces a model to determine possible impacts of changes in supply chain structures on freight transport demand. Examples are centralisation or vertical (des)integration within supply chains. The model first generates a population of establishments and commodity flows in space which is then manipulated according to different scenarios. It uses methods from transport planning and optimisation as well as scenario technique. To demonstrate its applicability a centralisation in food supply chain structures in Germany is analysed. The results show that a more educated discussion is needed for such changes since the range of possible impacts is large.

Abstract: Research has shown that employees who occupy more central positions in their organization's network have lower turnover. As a result, scholars commonly interpret turnover as the consequence of social networks. Based on Conservation of Resources theory, we propose an alternative coevolution perspective that recognizes the influence of changes in individuals' social network position on their thoughts of quitting (the consideration of turnover), but also posits that thoughts of quitting shape individuals' agency in maintaining and changing their social network. Extending previous research, we predict that creation (dissolution) of both friendship ties and advice ties are negatively (positively) related to subsequent thoughts of quitting. We then develop and test the novel hypotheses that for friendship ties, thoughts of quitting are positively related to tie retention and negatively related to tie creation (leading to network stasis), whereas for advice ties thoughts of quitting are negatively related to tie retention and positively related to tie creation (leading to network churn). In a longitudinal network analysis that assessed 121 employees across three time points, we find support for our hypotheses that thoughts of quitting affect network changes, but do not find that network changes affect thoughts of quitting.

Abstract: Research on value congruence rests on the assumption that values denote desirable behaviors and ideals that employees and organizations strive to approach. In the present study, we develop and test the argument that a more complete understanding of value congruence can be achieved by considering a second type of congruence based on employees’ and organizations’ counter-ideal values (i.e., what both seek to avoid). We examined this proposition in a time-lagged study of 672 employees from various occupational and organizational backgrounds. We used difference scores as well as polynomial regression and response surface analyses to test our hypotheses. Consistent with our hypotheses, results reveal that counter-ideal value congruence has unique relations to employees’ trust in the organization that go beyond the effects of ideal value congruence. We discuss theoretical and practical implications of this expanded perspective on value congruence.

Abstract: Practitioners repeatedly note that the everyday behavior of asking followers open questions and attentively listening to their responses is a powerful leadership technique. Yet, despite such popularity, these practices are currently under-theorized. Addressing this gap, we formally define the behavioral configuration of asking open questions combined with attentive listening as “Respectful Inquiry”, and then draw on Self-Determination Theory to provide a motivational account of its antecedents, consequences, and moderators within a leader-follower relationship. Specifically, we argue that Respectful Inquiry principally satisfies followers' basic psychological needs for competence, relatedness, and autonomy. Against this background, we highlight ironic contexts where Respectful Inquiry is likely to be especially rare, but would also be especially valuable. These ironic contexts include situations where interpersonal power difference, time pressure, physical distance, cognitive load, follower dissatisfaction, or organizational control focus are high. We additionally outline how the effect of Respectful Inquiry behaviors critically hinges upon the interaction history a follower has with a leader. More generally, we make the suggestion that the leadership field would benefit from complementing its traditional focus on “gestalt” leadership styles with research on concrete and narrow communicative behaviors, such as Respectful Inquiry.

Abstract: Organizations often pay greater salaries to higher-ranking executives compared to lower-ranking executives. While this method can be useful for retaining those at the organization’s apex, it may also incline executives at the bottom of the pay pyramid to see themselves at a disadvantage and thus exit the firm. Naturally, organizations often want to retain some of their lower-paid, but highly valuable executives; the question, then, is how organizations can reduce the turnover of lower-ranking executives. By integrating social with temporal comparison theory, we argue that, when executives earn relatively less than their peers, more pay growth (i.e., individual pay increases over time) leads to less turnover. By the same token, we also argue that pay growth is unrelated to the turnover of executives who already earn substantially more than their peers. The results of our analysis, which covered almost 20 years of objective data on a large sample of U.S. top executives, provide support for our theory.

Abstract: Objective: To characterize how schedulers spend their time interacting with external parties.Background: Time is the most critical resource at the disposal of schedulers; however its usage has been overlooked by prior empirical studies. Methods: Seven schedulers for a total of nineteen 8-hour shifts where observed. Detailed time data about their activities and how these where interrupted was collected. Results: Schedulers interrupt themselves significantly and most of their activities are triggered externally. Despite this, schedulers are able to decide in most situations which activity to perform next. Schedulers spend more time on their informational role than on their decisional role; mostly at the requests of others, suggesting insufficient information system support to others in the organization.Conclusion: Schedulers other main role, besides making scheduling related decisions is to relay information. This implies that schedulers are subject to several external requests for activities. However, due to asynchronous communication that e-mails provide, they are still able to decide on their own schedule to do tasks.Application: The methodology used can be used to evaluate an individual use of time, in particular for time-critical such as scheduling. The analysis may provide insights as to how to improve the efficiency of such jobs.

Abstract: We model a periodic review inventory system with non-stationary stochastic demand, in which a manufacturer is procuring a component from two available supply sources. The faster supply source is modeled as stochastic capacitated with immediate delivery, while the slower supply source is modeled as uncapacitated with a longer fixed lead time. The manufacturer’s objective is to choose how the order should be split between the two supply sources in each period, where the slower supply source is used to compensate for the supply capacity unavailability of the faster supply source. This is different from the conventional dual-sourcing problem, and motivated by the new reality of near-shoring options. We derive the optimal dynamic programming formulation that minimizes the total expected inventory holding and backorder costs over a finite planning horizon and show that the optimal policy is relatively complex. We extend our study by developing an extended myopic two-level base-stock policy and we show numerically that it provides a very close estimate of the optimal costs. Numerical results reveal the benefits of dual-sourcing under near-shoring, where we point out that in most cases the manufacturer should develop a hybrid procurement strategy, taking advantage of both supply sources to minimize its expected total cost.

Abstract: In large cities in emerging economies, traditional retail is present in a very high density, with multiple independently owned small stores in each city block. Consequently, when faced with a stockout, consumers may not only substitute with a different product in the same store, but also switch to a neighboring store. Suppliers may take advantage of this behavior by strategically supplying these stores in a coherent manner. We study this problem using consumer choice models. We build two consumer choice models for this consumer behavior. First, we build a Nested Logit model for the consumer choice process, where the consumer chooses the store on the first level and selects the product on the second level. Then, we consider an Exogenous Substitution model. In both models, a consumer may substitute at either the store level or the product level. Furthermore, we estimate the parameters of the two models using Markov chain Monte Carlo algorithm in a Bayesian manner. We numerically find that the Nested Logit model outperforms the Exogenous Substitution model in estimating substitution probabilities. Further, the information on consumers’ purchase records helps improve the estimation accuracies of both the first-choice probabilities and the substitution probabilities when the beginning inventory level is low. Finally, we show that explicitly including such substitution behavior in the inventory optimization process can significantly increase the expected profit.

Abstract: Tempelmeier and Hilger (2015) study the stochastic dynamic lot sizing problem with multiple items and limited capacity. They propose a linear optimization formulation for the problem based on a piece-wise linear approximation of the non-linear functions for the expected backorders and the expected inventory on hand. Building on the work of Tempelmeier and Hilger (2015), we correct an erroneous derivation of the linear optimization problem and propose an improved model.
