Community perception of low level anti-social behaviour by young people, and imagining a solution : an exploratory case study

Statham, Elaine January 2012 (has links)
Critics of anti-social behaviour policy (ASB) introduced by New Labour Government since 1997 argue that it is overly punitive, and criminalises what is often sub-criminal or nuisance behaviour. Further criticism is that policy implementation through formal channels has led to the public increasingly relying on formal agencies in the governance of ASB, and becoming less willing to play an active role. The catalyst for my research was two Community Safety Teams aim to reverse this trend. I have developed an innovative approach in the form of a booklet (Let s Talk) based on the under-researched Imagined Intergroup Contact model associated with the Intergroup Contact Theory which underpins Intergenerational Practice. My thesis centres on the piloting of the booklet in two regions in England, and the proposition that Intergenerational approaches can be a useful way of understanding and addressing tensions associated with perceived anti-social behaviour by young people . Drawing broadly on a social constructionist paradigm (Burr, 1995), and using an inductive case study approach, both quantitative and qualitative data were collected via various research tools. The sample included local residents, representatives of community organisations and the Community Safety Teams (CST). Data were coded and analysed using NVivo and SPSS. Theoretical data analysis was underpinned by the Integrated Threat Theory and the Social Cognitive Theory. Compared with other theories associated with Intergenerational Practice, the Integrated Threat Theory gave a more comprehensive explanation for intergenerational tensions. SCT gave new insights into the concept of agency in relation to the governance of ASB. My research identified anti-social behaviour that the CSTs felt did not warrant formal intervention, and the booklet received enthusiastic support from all parties consulted as an alternative, community-based approach. Reasons for a few individuals not wanting to adopt the booklet approach were identified; these included personal factors and social dynamics. My findings provided important knowledge for the future development and use of the booklet. This thesis makes a significant contribution to knowledge. Firstly, it extends the theoretical explanation of intergenerational tensions, and adds insights into the concept of governance and the theoretical underpinnings of Intergenerational Practice. Secondly, it advances implications for practice in relation to fully exploring social dynamics other than intergenerational issues, taking account of potential multigenerational factors, and being aware that preparatory activities to strengthen selfefficacy may be required.

Apprentissage social et mouvements antennaires chez l'abeille domestique (Apis mellifera L.) / Social learning and antennal mouvements in Honeybee (Apis mellifera L.)

Cholé, Hanna 24 September 2018 (has links)
Les interactions entre individus sont un socle vital pour l’organisation des colonies d’abeilles, en particulier lors du recrutement pour le butinage. Outre la communication de la localisation d’une source de nourriture par la fameuse danse, les abeilles recrutées apprennent les caractéristiques de l’odeur des fleurs butinées au cours de transferts de nectar (trophallaxie). Les mécanismes de cet apprentissage ne sont pas encore éclaircis car il est parfois effectif sans aucun transfert de nectar, suggérant que d’autres mécanismes, comme par exemple d’apprentissage social, sont impliqués. Nous avons reproduit cette interaction en laboratoire, suivant un protocole basé sur le conditionnement olfactif appétitif de la réponse d’extension du proboscis (REP). Ici, un composé odorant initialement neutre (Stimulus conditionnel) était associé à un contact avec une congénère (Stimulus Inconditionnel social), sans récompense sucrée. Nos expériences montrent que ce simple contact social entre congénères peut constituer un renforcement pour les abeilles. A la suite de cette association, celles-ci montrent donc des REP à l’odeur préalablement associée au contact social. Nos expériences montrent de plus que des contacts antennaires entre les abeilles sont indispensables à l’efficacité de cet apprentissage social, représentant un indice social tactile. Nous avons alors développé un dispositif permettant d’enregistrer les mouvements des antennes de manière précise et à haute vitesse (90 hz) et étudié les différents facteurs modulant les mouvements antennaires des abeilles. Les abeilles montrent des réponses contrastées et reproductibles à des odeurs de valeurs biologiques différentes. De plus, le couplage de ces enregistrements à des expériences de conditionnement associatif montre que ces réponses antennaires sont plastiques et modifiées par l’expérience des individus. Ce travail a permis de mettre en lumière un nouveau type d’apprentissage social chez les insectes et d’approfondir l’étude des mouvements antennaires comme indicateurs de l’état motivationnel, attentionnel et physiologique des abeilles ainsi que de la valence des stimuli perçus. / In honeybees, interactions between individuals are cornerstones for the organization of the colony, especially during recruitment for foraging. Besides learning the location of a food source thanks to the well-known dance, the recruited bees learn the characteristics of odors of foraged flowers through nectar transfer (trophallaxis). The underlying mechanisms are still unclear because this learning can occur without any nectar transfer, suggesting that other, probably social, learning mechanisms are involved. We reproduced this interaction in the lab, using a protocol based on the appetitive olfactory conditioning of the proboscis extension response (PER). Here, an initially neutral odorant (conditioned stimulus) was associated with a contact with a nestmate (social unconditioned stimulus), without any sugar reward. Our experiments show that this simple social contact between workers can act as a reinforcement for bees. As a result, they show PER to the odor previously associated with a social contact. We further demonstrate that antenna contacts are essential for the effectiveness of this social learning, representing a tactile social cue. We thus developed a system allowing to record bees’ antennal movements accurately and at high frequency (90 hz). We then determined the factors modulating bees’ antennal movements. First, we show that bees display contrasted and reproducible responses to odors of different biological values. Second, the coupling of these recordings with associative conditioning experiments shows that these antennal responses are plastic and modified by individual experience. This work has shed light on a new type of social learning in insects and has furthered our understanding of antennal movements as indicators of the motivational, attentional and physiological state of bees and of the valence of perceived stimuli.

Effects of real and imagined contact under conditions of socially acceptable prejudice

West, Keon P. A. January 2010 (has links)
The objective of this thesis was to examine the effectiveness of contact and imagined contact (a derivative of direct contact) in reducing intergroup prejudice when the prejudice in question is deemed socially acceptable. Studies focused on two populations that are targets of socially acceptable, prejudice – people suffering from schizophrenia in the U.K., and homosexual men in Jamaica. These target groups were selected because they are similar in that they are both targets of socially acceptable prejudice, but also because of their differences in that the stereotypes associated with them are quite dissimilar. The first part of the thesis empirically tested the assumption that the aforementioned populations are targets of socially acceptable prejudice. Two cross-sectional studies, one of which was also cross-cultural, measured motivation to control prejudice against these target groups, and compared it to motivation to control prejudice against targets of socially unacceptable prejudice. I found that motivation to control prejudice against people with schizophrenia in the U.K. was lower than motivation to control prejudice against Black people in the U.K. Also, motivation to control prejudice against homosexual men was higher in the U.K. and the U.S.A. than in Jamaica, and differences in motivation to control unspecified prejudice were significantly smaller. The second part examined the association between actual contact and prejudice for both populations. Two cross-sectional studies, one of which was also cross-cultural, found that contact was associated with less prejudice. This effect was mediated by intergroup anxiety in all cases, and also by fear in the case of people with schizophrenia. Furthermore, I found that contact was more strongly negatively associated with anti-homosexual prejudice in Jamaica, where the prejudice is socially acceptable, than it was in Britain, where the prejudice is not socially acceptable. The third part tested the effect of imagined contact, a form of extended contact, on prejudice against people with schizophrenia. Four experimental studies demonstrated that imagined contact can be an effective means of reducing prejudice against this group. However imagined contact must be conducted in very specific ways, otherwise it has the potential to increase prejudice against people with schizophrenia.

Hellénizace antické Thrákie ve světle epigrafických nálezů / Hellenisation of Ancient Thrace based on epigraphical evidence

Janouchová, Petra January 2017 (has links)
Petra Janouchová - Hellenisation of Ancient Thrace based on epigraphical evidence Abstract: More than 4600 inscriptions in the Greek language come from Thrace, the area located in the Southeastern Balkan Peninsula. These inscriptions provide socio-demographic data, allowing the study of changing behavioural patterns in reaction to cross-cultural inter- actions. Traditionally, one of the essential indications of the influence of the Greek culture on the population of ancient Thrace was the practice of commissioning inscriptions in the Greek language. By using quantitative and systematic analysis, the inscriptions can be studied from a new perspective that places them into broader regional context. I use this methodology to assess the concept of Hellenization as one of the possible interpretative frameworks for the study of ancient society. Using a spatiotemporal analysis of inscrip- tions, this research shows that epigraphic production cannot be solely linked with the cultural and political influence of Greek speaking communities. However, the phenome- non of epigraphic production is closely connected to the growth of social complexity and consequent changes in the behavioural patterns of the population. The growth in social complexity is followed by an increase of epigraphic production of public and private...
