Bereitschaft zur Teilnahme an betrieblichen Freiwilligenprogrammen: Die Effekte von innerbetrieblichen Referenzgruppen und des regulatorischen Fokus

Die vorliegende Studie analysiert, wie innerbetriebliche Referenzgruppen und der regulatorische Fokus von Kommunikationsbotschaften die Bereitschaft zur Teilnahme an betrieblichen Freiwilligenprogrammen beeinflussen. Die Ergebnisse einer experimentellen Studie zeigen, dass sich der Referenzgruppeneinfluss sowie der regulatorische Fokus von Kommunikationsbotschaften unterschiedlich auf verschiedene Facetten der individuellen Handlungsintention niederschlagen. Ferner wird auch gezeigt, dass die Referenzgruppeneinflüsse mit dem chronischen regulatorischen Fokus sowie mit dem regulatorischen Fokus von Kommunikationsbotschaften interagieren können. Handlungsempfehlungen für die Gestaltung der Kommunikation mit Mitarbeitern und Ansatzpunkte für die zukünftige Forschung werden diskutiert.This study investigates how organizational reference group influences and regulatory focus affect the willingness of individuals to participate in employee volunteering programs. The results of an experimental study reveal that organizational reference group influences and the regulatory focus of communication messages have an impact on different aspects of the willingness of individuals to participate in employee volunteering programs. Moreover, the current study shows that the effects of organizational reference groups interact with two facets of the regulatory focus.

Guest editorial: Craft beers: consumer perception, motivation and demand in a fast-rising market

Whether observing the scene that materialises in the background of a canvas by connecting seemingly unrelated points is a curious and pleasurable experience, painting it to reflect reality is undoubtedly a captivating but daunting challenge. We are honoured to be guest editors of this special issue of the IJWBR, in which we are invited to unveil the painting of craft beer (CB) studies in economics and marketing. Thus, this call for papers was inspired by the intention to frame and strengthen the knowledge of managerial and marketing dynamics in the CB sector worldwide and to serve as a valuable reference for business operators

Satisfaction With Informal Volunteering During the COVID-19 Crisis: An Empirical Study Considering a Swiss Online Volunteering Platform

The COVID-19 pandemic has led to a huge wave of compassion. In particular, online volunteering platforms established channeling help for high-risk groups. It is unclear under which conditions volunteers were satisfied with their COVID-19 volunteering mediated by these platforms and whether they will continue their engagement after the crisis. Therefore, and considering personal susceptibility to COVID-19 infection, this study analyzes the effects of different platform support for volunteers and the fulfillment of volunteers' motives. The study is based on an online survey of a sample of 565 volunteers who registered at and were placed by a Swiss online platform. Fulfillment of distinct volunteer motives and platform support drive COVID-19 volunteering satisfaction. Moreover, motive fulfillment and platform-related support indirectly impact willingness to volunteer long-term via volunteering satisfaction. Finally, the empirical results show that motive fulfillment and the effect of platform support are contingent on perceived susceptibility to infection

Consumer outrage: Emotional reactions to unethical corporate behavior ☆

Unethical corporate conduct frequently leads to public outrage, which in turn triggers detrimental consumer behavior, such as consumer boycotts. However, few studies examine the effects of unethical corporate behavior on consumer emotions. To address this gap, the present work develops and validates a model of consumer outrage. The analysis suggests that consumer outrage is a compound emotion that comprises affective and cognitive experiences. Moreover, the results indicate that consumer outrage is a major trigger of boycotting behavior and that gender affects the predictions of the outrage model. The paper provides implications for management and suggestions for further research

Antenna with optimized pattern for simultaneous reception of terrestrial signals and signals of geostationary satellites

The link margin for satellite communication services targeting mobile users is tight. This leads to reception problems in areas with strong fading scenarios like urban areas or forested areas with dense foliage. In order to avoid loss of service in urban areas with week coverage by satellite signals, terrestrial repeaters are used. Therefore in the design of antennas for mobile reception of satellite services, an optimized characteristics for the satellite constellation, as well as an adequate coverage of the terrestrial repeaters has to be accounted for. In this paper an antenna with optimum shaped pattern for the satellite mode and adjustable gain for vertical polarization is investigated. Beside constraints regarding the radiation pattern, measurements concerning the dependence of the antenna on noise temperature and therefore the behavior in real noisy environments are carried out. A comparison with a conventional antenna shows the high performance of the new antenna in combination with a very low volume requirement

The impact of preferences for clinical and managerial leadership roles on the willingness to apply for a medical leadership position : analysis of gender differences among a sample of German senior physicians

Background: The hybrid role (clinical and managerial leadership tasks) of physicians in medical leadership positions (MLPs) is a driver of the attractiveness of these positions. The increasing feminization of the medical profession makes gender-related preferences for hybrid roles relevant. Purpose: The current study uses the (EPL) career aspirations framework to analyze the (gender-related) effects that efficacy beliefs, motivations, and preferences for clinical leadership and managerial leadership have on the willingness of chief physicians to apply for an MLP. Methodology: A survey of senior physicians in German university hospitals yielded a sample size of N?=?496. The resulting data were analyzed using a structural equation modeling approach. Findings: The results confirm the low preference for MLPs among senior physicians, which is mainly affected by preferences for managerial leadership tasks. Female senior physicians perceive the position of an MLP to be less attractive than their male counterparts do, and female physicians’ willingness to apply for an MLP is concurrently driven by their preferences for clinical leadership and managerial leadership tasks. Practical implications: Mentoring programs could boost female senior physicians’ preparedness for MLPs. Further, flexibility in fulfilling managerial leadership tasks could be promoted to make MLPs more attractive to women

Asymmetrien eines Ethernet-Systems und deren Auswirkungen auf die Störaussendung im automobilen Umfeld

Seit Jahren ist ein Zuwachs von elektronischen Komponenten im Fahrzeug zu beobachten. Der Wunsch nach mehr Komfort und Sicherheit trägt hier maßgeblich dazu bei. Um den Anforderungen gerecht zu werden, sind schnelle Übertragungssysteme im Fahrzeug erforderlich, die die großen Datenmengen verteilen und verarbeiten können. Ein solches System ist zum Beispiel Ethernet, mit dem periphere Komponenten mit hohen Datenraten vernetzt werden können. Eine spezielle Variante für den automobilen Einsatz stellt dabei das OABR-Ethernet (Open-Alliance-BroadR-Reach) dar. Dieses Kommunikationssystem nutzt eine bidirektionale Übertragungstechnik um 100MBit/s über eine ungeschirmte Zweidrahtleitung (UTP) zu übertragen. Eine weitere Besonderheit ist die Begrenzung des Nutzsignalspektrums durch einen Tiefpassfilter auf ca. 70MHz. Dadurch wird das Risiko einer Störung im UKW-Bereich minimiert. Der Einsatz dieses schnellen Übertragungssystems im Fahrzeug stellt jedoch eine große Herausforderung an die Elektromagnetische-Verträglichkeit (EMV) dar. Bereits kleine Asymmetrien im Übertragungspfad führen dazu, dass ein Teil des Nutzsignals (Gegentaktsignal) durch Modenkonversion in ein Störsignal (Gleichtaktstörung) umgewandelt wird - nachfolgend Modenkonversion genannt. Diese Gleichtaktstörungen können über die UTP-Leitung abstrahlen und zu Grenzwertüberschreitungen bei Störaussendungsmessungen führen. Jede Komponente im Übertragungspfad trägt maßgeblich zur Modenkonversion und somit zur Störaussendung bei. Diese Arbeit soll eine Übersicht über die Modenkonversion der einzelnen Elemente der physikalischen OABR-Schnittstelle geben. Diese Elemente sind im Einzelnen der Tiefpassfilter (LPF), die Common-Mode-Choke (CMC), die differentiellen Mikrostreifenleitungen (DML) sowie die Platinen- und In-Line-Stecker

Charakterisierung der Einflussfaktoren von einem Nahfeld Antennen Test

In der Automobilindustrie führt die Verwendung von immer hochbitratigeren Bus- und Kommunikationssystemen bei gleichzeitig steigender Packungsdichte der elektrischen Komponenten im Fahrzeug zu einer Nahfeldverkopplung von elektrischen Systemen. Um diese Verkopplung bereits auf der Komponenten- bzw. Systemebene abzusichern, wird ein Tischaufbau nach der Nahfeld-Antennen Testmethode (NFA-Test) konstruiert (firmeninterne Norm). In dieser Arbeit werden bestimmte geometrische Einflussfaktoren des Tischaufbaus auf die Messergebnisse der NFA-Messung untersucht. Die Messungen erfolgen mit einem vektoriellen Netzwerkanalysator (VNA). Für die Verifizierung der Messergebnisse wird eine 3D Simulation basierend auf der Momentenmethode (MoM) durchgeführt. Abschließend wird repräsentativ eine ermittelte Abhängigkeit mit Hilfe einer Emissionsmessung unter Anwendung eines Automotive Ethernet Steuergerätes für einen Anwendungsfall herangezogen. Diese Emissionsmessung wird mit einem Spektrumanalysator durchgeführt

Captive gibbons (Hylobatidae) use different referential cues in an object-choice task: insights into lesser ape cognition and manual laterality

Background Utilization of visual referential cues by non-human primates is a subject of constant scientific interest. However, only few primate species, mostly great apes, have been studied thoroughly in that regard, rendering the understanding of phylogenetic influences on the underlying cognitive patterns difficult. Methods We tested six species of captive gibbons in an object-choice task (n = 11) for their ability to interpret two different pointing gestures, a combination of body orientation and gaze direction as well as glancing as referential cues. Hand preferences were tested in the object-choice task and in a bimanual tube task (n = 18). Results We found positive responses to all signals except for the glancing cue at the individual as well as at the group level. The gibbons’ success rates partially exceed results reported for great apes in comparable tests and appear to be similarly influenced by prior exposure to human communicative cues. Hand preferences exhibited by the gibbons in the object-choice task as well as in a bimanual tube task suggest that crested gibbons (Nomascus sp.) are strongly lateralized at individual but not at population level for tasks involving object manipulation. Discussion Based on the available data, it can be assumed that the cognitive foundations to utilize different visual cues essential to human communication are conserved in extant hominoids and can be traced back at least to the common ancestor of great and lesser apes. However, future studies have to further investigate how the social environment of gibbons influences their ability to exploit referential signals. Gibbons’ manual laterality patterns appear to differ in several aspects from the situation found in great apes. While not extensive enough to allow for general conclusions about the evolution of hand preferences in gibbons or apes in general, our results add to the expanding knowledge on manual lateralization in the Hylobatidae
