Nest defence against avian brood parasites is promoted by egg-removal events in a cowbird–host system
2011
Recent studies of birds have found that the antiparasite behaviour of host species is modified by social learning. We tested whether individual or social learning modifies the nest defence of yellow warblers, Setophaga petechia, against the parasitic brown-headed cowbird, Molothrus ater. Using field experiments, we exposed warblers to simulated events of nest parasitism and predation, or allowed them to observe conspecifics mobbing a cowbird. Intensity of nest defence by yellow warblers was greater after simulated threats at their nest than after they had observed mobbing of cowbirds by conspecifics. Warblers defended their nests more aggressively when they perceived a cowbird as an egg pre…

Hosts of brood parasitic cuckoos often employ mobbing attacks to defend their nests and, when mobbing is costly, hosts are predicted to adjust their mobbing to match parasitism risk. While evidence exists for fine-tuned plasticity, it remains unclear why mobbing does not track larger seasonal changes in parasitism risk. Here we test a possible explanation from parental investment theory: parents should defend their current brood more intensively as the opportunity to replace it declines (re-nesting potential), and therefore “counteract” any apparent seasonal decline to match parasitism risk. We take advantage of mobbing experiments conducted at two sites where reed warblers (Acrocephalus sc…
PSYCHOLOGICZNE I PRAWNE ASPEKTY MOBBINGU W MIEJSCU PRACY
2018
Przemoc w miejscu pracy pojawia się z coraz większą a zarazem niepokojącą częstotliwością. Mobbing traktowany jest jako przykład patologii obserwowanej w organizacji. Stąd konieczność spojrzenia na mobbing w sposób wieloaspektowy. Celem artykułu jest przybliżenie psychologicznej natury zjawiska mobbingu, a także wskazanie na mobbing w kontekście polskiego prawa pracy. W artykule zwrócono uwagę na dwie przestrzenie, w jakich należy przyjrzeć się przemocy w organizacji. Pierwsza część artykułu poświęcona jest aspektom związanym z psychologią zdrowia i psychologią organizacji. Druga część artykułu poświęcona jest przestrzeni prawa pracy. W pierwszej części artykułu skupiono się na psychologicz…
Further Evidence for Criterion Validity and Measurement Invariance of the Luxembourg Workplace Mobbing Scale
2020
Abstract. Workplace mobbing has various negative consequences for targeted individuals and are costly to organizations. At present it is debated whether gender, age, or occupation are potential risk factors. However, empirical data remain inconclusive as measures of workplace mobbing so far lack of measurement invariance (MI) testing – a prerequisite for meaningful manifest between-group comparisons. To close this research gap, the present study sought to further elucidate MI of the recently developed brief Luxembourg Workplace Mobbing Scale (LWMS; Steffgen, Sischka, Schmidt, Kohl, & Happ, 2016 ) across gender, age, and occupational groups and to test whether these factors represent im…
Mobbing in Schools and Hospitals in Uruguay: Prevalence and Relation to Loss of Status.
2017
In the present study in secondary schools and hospitals in Uruguay ( N = 187), we examined the relationship between feeling the victim of mobbing and a perceived loss of status. Nearly all forms of mobbing were more prevalent among hospital employees than among school employees. Among hospital employees, 40.4%, and among school employees, 23.9% reported being the victim of mobbing at least once a week. Being the victim of mobbing was, in both hospitals and schools, more prevalent among older employees, and in hospitals, among employees who were more highly educated and who had been employed for a longer time. Men and women did not differ in reporting that one was a victim of mobbing, but m…
Influence of Some Psychosocial Factors on Mobbing and its Consequences Among Employees Working with People with Intellectual Disabilities
2012
Background The problem of mobbing has attracted a great deal of attention over the past few years. This concern has increased the study of the phenomena, which has resulted in many scientific publications. Mobbing has been characterized as an emerging risk at work. The aim of this study was to analyse the influence of some psychosocial factors at work ‐ role clarity, interpersonal conflicts and social support ‐ on mobbing and its consequences ‐ that is, inclination towards absenteeism and psychosomatic disorders. Materials and methods The sample included 422 employees working with people with intellectual disabilities. Structural equation modelling (SEM) was used to test the hypotheses. Res…
Straining at work and its relationship with personality profiles and individual consequences in healthcare workers (HCWs)
2020
Straining is an attenuated form of mobbing, in which the continuity of vexatious actions is not driven by a discriminatory intent. With the objective of testing the possible moderating role of personality in the relationship between perceptions about straining at work and individual consequences, a correlational design research involved 374 healthcare workers (HCWs) from two Italian hospitals. The following questionnaires were administered: (1) Short Negative Acts Questionnaire (S-NAQ), to assess discriminative actions at work)
Use of social over personal information enhances nest defense against avian brood parasitism
2011
Interactions with conspecifics influence the behavioral repertoire of an organism, as they apply to foraging techniques, song acquisition, habitat selection, and mate choice. Few workers have studied the role of social interactions in molding defense responses, especially the defense of the nest. We tested the effect of social interaction on nest defense of the reed warbler (Acrocephalus scirpaceus), one of the main hosts of the brood-parasitic common cuckoo (Cuculus canorus) in Europe. This parasite reduces its host’s breeding success; therefore, any response that prevents successful parasitism should be selected. Because of their high nesting density and consistent cuckoo-specific respons…

Mobbing, Bullying und andere Aggressionen unter Schülern als Quelle von Schulstress: Inwieweit sind die "Opfer" daran beteiligt?
2008
Schulstress kommt in erheblichem Maße auch durch aggressive Interaktionen zwischen Schülern zustande. Aggressionen in der Schule können vielfältige Formen annehmen und verschiedene Ursachen haben. In diesem Beitrag geht es um Bullying, Mobbing und relationale Aggression unter Schülern. Wichtige Forschungsbefunde zu den verschiedenen Aggressionsformen werden dargestellt. Anschließend wird eine psychoanalytische Behandlung einer Jugendlichen wegen Mobbing vorgestellt. Die Therapie erstreckte sich über 70 Stunden und umfasste auch begleitende Elterngespräche. Der Behandlungsverlauf verdeutlicht, dass es wichtig ist, die eigene Beteiligung der Schülerinnen und Schüler am Auslösen und Aufrechter…
