Preis-Promotion-Framing – Ein Überblick zum Stand der Forschung

This article reviews published literature and provides an overview on present empirical evidence about the framing of price promotions. Concerning explicit price reductions (discounts, coupons, rebates), the effects of advertised reference prices and different frames of price discounts (relative versus absolute price discount, objective versus tensile price claims) on consumers’ reactions are discussed. Furthermore, the article examines empirical results on implicit price reductions (volume packs, free extra products) as well as on sale signs and restrictions (e.g. purchase limits, time limits) as popular ways of framing a deal. The key findings point out that framing a price promotion in different ways can affect consumers’ perceptions and evaluations of the deal. Based on the reviewed literature, the concluding section provides managerial implications and an agenda for further research.     

A decision support methodology for strategic planning in maritime transportation

This paper presents a decision support methodology for strategic planning in tramp and industrial shipping. The proposed methodology combines simulation and optimization, where a Monte Carlo simulation framework is built around an optimization-based decision support system for short-term routing and scheduling. The simulation proceeds by considering a series of short-term routing and scheduling problems using a rolling horizon principle where information is revealed as time goes by. The approach is flexible in the sense that it can easily be configured to provide decision support for a wide range of strategic planning problems, such as fleet size and mix problems, analysis of long-term contracts and contract terms. The methodology is tested on a real case for a major Norwegian shipping company. The methodology provided valuable decision support on important strategic planning problems for the shipping company.     

Followers' Personality and the Perception of Transformational Leadership: Further Evidence for the Similarity Hypothesis

Managers and supervisors are thought to affect their followers' attitudes and behaviour. Within leadership research, behaviour of leaders and managers is usually considered as the independent variable whilst followers' reactions are considered the dependent variable. In this study, we reverse this order and investigate the degree to which the evaluation of leadership is a result of followers' perceptions and attributions. In order to corroborate and extend previous experimental research, a field study was conducted to analyse the influence of followers' personality and perceived leader personality on followers' perception of leadership within an organizational setting. The results provide further evidence that followers' personality influences the perception of transformational leadership and commitment to the supervisor. Moreover, the perception of leaders' personality was related to the perception of leadership and commitment to the supervisor. The finding that the perception of supervisors' personality mediates both the relationship between followers' personality and the perception of leadership and commitment provides support for the similarity hypothesis. Results are discussed in the light of feedback and leader development.     

The Safeguarding Effect of Governance Mechanisms in Inter‐firm Exchange: The Decisive Role of Mutual Opportunism

This study empirically investigates the safeguarding effect of (1) administrative control, (2) a dominant power position and (3) relational norms, on opportunistic behaviour of suppliers, by means of a survey among 624 information and communication technology professionals in Dutch municipalities. The findings indicate that individual effectiveness of relational norms, particularly in terms of flexibility and solidarity, was most prominent. Administrative control and power did not show a significant impact on supplier opportunism in our sample. Research into the simultaneous use of several safeguards against opportunism generated the finding that different relational norms fortify each other's safeguarding effect. Furthermore, we demonstrate that supplier opportunism is only mitigated by a dominant power position when the buyer does not exploit its favourable position and the buyer does not behave opportunistically. Hence, power seems to have a safeguarding effect only when it is not used.     

A Quality Risk Management Model Approach for Cell Therapy Manufacturing

International regulatory authorities view risk management as an essential production need for the development of innovative, somatic cell‐based therapies in regenerative medicine. The available risk management guidelines, however, provide little guidance on specific risk analysis approaches and procedures applicable in clinical cell therapy manufacturing. This raises a number of problems. Cell manufacturing is a poorly automated process, prone to operator‐introduced variations, and affected by heterogeneity of the processed organs/tissues and lot‐dependent variability of reagent (e.g., collagenase) efficiency. In this study, the principal challenges faced in a cell‐based product manufacturing context (i.e., high dependence on human intervention and absence of reference standards for acceptable risk levels) are identified and addressed, and a risk management model approach applicable to manufacturing of cells for clinical use is described for the first time. The use of the heuristic and pseudo‐quantitative failure mode and effect analysis/failure mode and critical effect analysis risk analysis technique associated with direct estimation of severity, occurrence, and detection is, in this specific context, as effective as, but more efficient than, the analytic hierarchy process. Moreover, a severity/occurrence matrix and Pareto analysis can be successfully adopted to identify priority failure modes on which to act to mitigate risks. The application of this approach to clinical cell therapy manufacturing in regenerative medicine is also discussed.     

Understanding information systems infrastructure in engineering SMEs: A case study

The benefits of integrated enterprise-wide information systems (IS), such as Enterprise Resource Planning (ERP) systems, are widely accepted. The implementation of such systems in large organisations is established with many in their second or third generation. However, in small to medium-sized enterprises (SMEs) the maturity and extent of their IS infrastructure is less clear. In engineering SMEs, this infrastructure needs to support not only business processes but also the activities of design and manufacture.In this case study, our goal is to provide a better understanding of current IS infrastructure, the functional elements of IS infrastructure, integration and expenditures are explored in ten engineering SMEs. A model of IS functionality is developed and used to identify and classify functional elements within the firms and to compare and contrast the IS infrastructures. The findings are contrasted with the SME literature and conclusions and implications developed.     

Developments in implicit leadership theory and cognitive science: Applications to improving measurement and understanding alternatives to hierarchical leadership

After reviewing key findings regarding leadership categorization theory, we develop new perspectives regarding the design of behavioral measures of leadership and the implications of shared leadership and complex adaptive leadership conceptualizations of leadership. In particular, by applying recent developments in cognitive science, we explain how an understanding of symbolic, connectionist, and embodied representations of knowledge can benefit behavioral measures of leadership. Additionally, we address some practical issues associated with the measurement of leadership and argue that ratings which tap episodic memory at the event level may be more meaningful than ratings based on semantic memory. Finally, we discuss how notions of shared leadership and of leaders as catalysts for complexity can create unique complications for leadership perceptions, coordinated behavior within a group, and the measurement of leadership.
