Interest in group moods as an emergent phenomenon of group members’ interactions has significantly increased over the past two decades (Barsade & Gibson, 2007). Most studies focused particularly on understanding the effects of group moods on group processes (Barsade, 2001, Baartel & Saavedra, 2000, Barsade, Ward, Turner & Sonnenfled, 2000, Chiayu Tu, 2009) and group performance (Seung -Yoon Ree, 2006, Jordan, Lawrence & Troth, 2006). However, research investigating the antecedents of group moods is still scant. The current study fills this gap by focusing on the affective potential of group conflict. In this sense, group conflict focuses on how differences of opinion (task conflict) and person-related disagreements (relationship conflict) trigger group moods that differ in their valence (positive and negative) and level of activation (activated and unactivated) (Baartel & Saavedra, 2000). In this context, the group’s ability to define and understand its moods, their cause, evolution and relations between them - ability known as group emotional intelligence (Salovey & Mayer, 1990) - is expected to buffer the relation between conflict and group moods. By studying group moods in relation to group conflict, the current study extends previous research by considering group moods’ antecedents and not only their consequences. This contributes to a better understanding of group affect dynamics. In addition, the current study investigates different nuances of group moods given by different types of conflict. Whether an affect has a positive or negative valence, or whether it is activated or inactivated, has implications upon the further group dynamics.
Managing nursing personnel properly is of critical importance as these resources comprise a vast share of the hospital's operational costs. The organisational support and the managerial policy decisions on the scheduling level are important determinants for the nurses' working conditions and the related quality of care. In this paper, we gain insights and understanding in the consequences and outcomes of various personnel re-rostering characteristics and strategies. We explore the boundaries of the time horizon and the nurse staffing size to consider for the nurse re-rostering problem based on computational experiments in a real-life problem environment.
The efficient and effective management of nursing personnel is of critical importance in a hospital's environment comprising a vast share of the operational costs. The adopted nurse workforce practices and policies highly affect the nurses' working conditions and the provided quality of care. Policy decisions on the staffing level have an impact on the outcome of the scheduling level and vice versa. Isolated reasoning typically leads to suboptimal decisions often resulting in ineffective outcomes of care. In order to overcome these inefficiencies, we propose in this paper a new integrative nurse staffing and shift scheduling approach. We test and assess the benefits of our approach in a reallife environment. Moreover, we examine the impact of several personnel policies on the staffing decision.
Attitudes and preferences do not always prove to be good predictors of actual behavior. Following the call for moderating variables to get a better idea of when and for whom attitude–behavior consistency exists, the current paper focuses on mood as a potential situational moderator. Results from three online studies demonstrate that (1) mood significantly affects attitude–behavior consistency, (2) not the decision style that mood activates (i.e., a deliberative style under negative mood versus an intuitive decision style under positive mood), but a fit in decision style respondents use during attitude formation and decision making underlies this mood effect, and (3) this mood effect holds for individuals who tend to experience their emotions intensively (i.e., high affect intensity individuals), but reverses for individuals who experience their emotions less intensively (i.e., low affect intensity individuals).

This study examines the role of the decision environment in how well business intelligence (BI) capabilities are leveraged to achieve BI success. We examine the decision environment in terms of the types of decisions made and the information processing needs of the organization. Our findings suggest that technological capabilities such as data quality, user access and the integration of BI with other systems are necessary for BI success, regardless of the decision environment. However, the decision environment does influence the relationship between BI success and capabilities, such as the extent to which BI supports flexibility and risk in decision making.
Process mining researchers have primarily focused on developing and improving process discovery techniques, while attention for the applicability of process mining has been below par. As a result, there only exists a partial fit with the traditional requirements for compliance checking and risk management.
This paper proposes a comprehensive rule-based process mining approach for a timely investigation of a complete set of enriched process event data. Additionally, the contribution elaborates a two-dimensional business rule taxonomy that serves as a source of business rules for the comprehensive rule-based compliance checking approach. Finally, the study provides a formal grounding for and an evaluation of the comprehensive rule-based compliance checking approach.
Entrepreneurial marketing has emerged as a recent perspective within the marketing field, taking the challenges and characteristics of small firms and founding teams into account. Specifically, in the early stages of entrepreneurial marketing, besides potential customers a variety of other stakeholders tend to be in the center of attention. Among these stakeholders, business angels as early-stage investors represent a vital target group. In this paper, we aim to shed light on entrepreneurial marketing in the early phases of new venture creation, in which entrepreneurial firms have an inherent need to market the value of a business opportunity toward potential investors. In particular, we contribute to the literature by introducing the business model as a narrative device for the marketing of early-stage new ventures toward potential business angels. In this regard, the business model is suggested as playing a critical role through making the inherent economic value of a technology explicit. Building on narrative theory, we investigate the role that the business model plays in the decision-making process of 17 business angels. Based on our findings, we propose a model that links the business model to a business angel's interpretation of an investment opportunity and discuss implications for theory and practice.

It has been observed that ad-evoked feelings exert a positive influence on brand attitudes. To investigate the empirical generalizability of this phenomenon, we analyzed the responses of 1576 consumers to 1070 TV commercials from more than 150 different product categories. The findings suggest five empirical generalizations. First, ad-evoked feelings indeed have a substantial impact on brand evaluations, even under conditions that better approximate real marketplace settings than past studies did. Second, these effects are both direct and indirect, with the indirect effects largely linked to changes in attitude toward the ad. Third, these effects do not depend on the level of involvement associated with the product category. However, fourth, the effects are more pronounced for hedonic products than utilitarian products. Finally, these effects do not depend on whether the products are durables, nondurables, or services, or whether the products are search goods or experience goods.

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.
