Title: Organisationaler Zynismus – Phänomen, Ursachen, Folgen und Maßnahmen
Abstract:
Im Vortrag soll ein Überblick über die bisherige Forschung zu dieser Form destruktiv-negativer Einstellungen von Beschäftigten gegenüber dem eigenen Arbeitsgeber gegeben werden. Schwerpunkte liegen darauf, die Hintergründe der Entstehung der Problematik in der sog. VUKA-Welt zu beleuchten und die besonderen Herausforderungen in Zeiten des Fachkräftemangels zu verdeutlichen. Das Phänomen wird begrifflich genauer gefasst und von anderen organisationsbezogenen Einstellungen wie Identifikation, Commitment oder Entfremdung abgegrenzt. Im weiteren sollen dann erste Erkenntnisse über dessen Prävalenz, die wichtigsten Ursachen und Folgen von Zynismus am Arbeitsplatz basierend auf der bisherigen Forschung analysiert werden. Der Vortrag schließt mit praktischen Implikationen und arbeitet zukünftige Forschungsthemen und -fragestellungen heraus.

Titel: Instrumental Leadership in the Extended Full‑Range of Leadership Model: A Meta‑Analysis Addressing Research Gaps
Abstract:
Instrumental leadership (IL) combines the setting of strategic goals with ensuring their implementation by employees, thereby positioning itself as an extension of the full range of leadership theory (FRLT) to form an expanded FRLT (eFRLT). Despite its theoretical appeal, empirical research on IL remains limited and has not been reviewed quantitatively yet. This first-ever meta-analysis therefore quantifies (a) the intercorrelations of IL with FRLT dimensions and (b) the relationships between IL and behavioral, attitudinal, change-oriented, and well-being outcomes. A total of 76 articles (with k = 103 samples and N = 31,231 participants) were included in the meta-analysis. The results confirm the suspected positive relationships between IL and transformational and transactional leadership, and the negative relationship between IL and laissez-faire. In addition, positive relationships between IL and behavioral, attitudinal, change-oriented, and well-being outcomes were found. Next, (c) incremental validity was tested after controlling for FRLT behaviors and confirmed for the behavior-oriented outcome criteria. The results of this meta-analysis and the limitations of previous primary studies on IL have several important implications for IL future research. Aspects of causality, method variance, and the use of questionnaires will be discussed in the presentation.

Analyzing the operations in a multipurpose port terminal: a case study of DPW San Antonio, Chile.Abstract:
In this talk, some results of the current collaboration with the multipurpose port terminal DPW San Antonio in Chile will be presented under the scope of a research grant that aims to provide decision support systems to aid the planning decisions of port managers. The main operations and policies for berth allocation, capacity planning, and storage space policies will be discussed, emphasizing differences with specialized terminals. Although the analysis focuses on containers, other challenges are present. We will briefly discuss some of the main disruptions the port faces and then describe the proposed mathematical models for capacity planning (or workload assignment) and the storage space allocation at the yard. Further challenges/opportunities for research extensions will also be discussed.

Allocation of dynamic inductive charging infrastructures on airport apronsAbstract:
In the attempt to reduce the CO2 footprint of the aviation sector, airport ground vehicles such as passenger buses are increasingly being electrified, hence requiring potentially large batteries and charging stations as well as long charging downtimes. As a technological alternative to conductive charging of those vehicles, we consider the dynamic inductive charging technology, with which the vehicle's batteries can be charged wirelessly while the vehicle is in motion. The features of the airport aprons and their special traffic flows make this technology particularly attractive. However, if this technology were to be used, a difficult spatial allocation problem of its technical components would have to be solved. We describe this strategic planning task, develop alternative models to represent the underlying allocation problem and report numerical results on the solvability of the different modeling variants and the performance of a specific heuristic algorithm.

Planning marine protected areas under the CCAMLR regime: The case of the Weddell SeaAbstract:
The Global Biodiversity Framework sets an ambitious "30×30" conservation target, aiming to protect 30% of the Earth’s land and sea through designated protected areas. However, we're still falling short, with ocean protection currently at just 8.2%. Most existing marine protected areas (MPAs) are small-scale and primarily within national jurisdictions, leaving much work to be done. In international waters, several initiatives are underway to establish large-scale MPAs, particularly in the Southern Ocean under the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).One of these initiatives is the Weddell Sea MPA Phase 1 (WSMPA P1), initiated in 2013 and spearheaded by Germany under the EU's leadership. The WSMPA P1 aims to conserve one of the world’s last pristine marine areas, known for its vulnerable ecosystems and unique biodiversity, while also serving as a tool for enhancing the region's resilience to climate change. Over the years, the WSMPA P1 proposal has garnered "best science currently available" endorsements from the CCAMLR Scientific Committee and increasing support from CCAMLR Member States. By 2023, ten co-sponsors had backed the EU's proposal, but unanimous adoption remains elusive, with some member states opposing the need for MPAs.
In presenting the WSMPA P1 initiative, I will walk through the planning steps involved in developing an MPA in the high seas of the Southern Ocean under the CCAMLR regime. At the end of my talk, I will provide an outlook on the current situation regarding the establishment of CCAMLR MPAs and show that best scientific practices may not be sufficient to achieve the consensus and political momentum ultimately required for the designation of MPAs in the Southern Ocean.

Abstract: This presentation introduces the concept of intra-brand image confusion (IBIC) covering its components and consequences. Complementing the conceptualization empirical evidence from the automotive industry and the market for smart phones will be presented. Explorative factor analyses were conducted in order to assess the components of IBIC. Structural equation modeling reveals the extent and consequences of IBIC. Multiple regressions were conducted to further explore non-linear response at the sub-domain and higher-order construct level. The results confirm and solidify previous results on the relevance of the construct of IBIC. This study supports the relevance of intra-brand image confusion’s three components. A novel contribution arises from the fact that customers with a moderate involvement level are more confused than people with lower involvement levels. A U-shaped response indicates that lower involved prospective customers are at higher risk of a confusion by too broad assortments. Brand managers are well advised to pay strong attention to the structure of an assortment and to sub-brands to prevent the occurrence of an IBIC.
The talk will be on-site in U3-140. In addition, it is planned to stream the talk via Zoom. Participation should be possible by using the following credentials: https://uni-bielefeld.zoom-x.de/j/66353636480?pwd=ajlYUGh0MWxLTXcvUUVXQWVldElJdz09 (Meeting-ID: 663 5363 6480, Passwort: 305532).

Abstract: We combine nonparametric price response modeling and dynamic pricing. In particular, we model sales response for fast-moving consumer goods sold by a physical retailer using a Bayesian semiparametric approach and incorporate the price of the previous period as well as further time-dependent covariates. All nonlinear effects including the one-period lagged price dynamics are modeled via P-splines, and embedding the semiparametric model into a Hierarchical Bayesian framework enables the estimation of nonlinear heterogeneous (i.e., store-specific) immediate and lagged price effects. The nonlinear heterogeneous model specification is used for price optimization and allows the derivation of optimal price paths of brands for individual stores of retailers. In an empirical study, we demonstrate that our proposed model can provide higher expected profits compared to competing benchmark models, while at the same time not seriously suffering from boundary problems for optimized prices and sales quantities. Optimal pricing policies for brands are determined by a discrete dynamic programming algorithm.
