Social Behaviour and reproductive cycles in captive ring tailed lemurs lemur catta
Journal of Zoology, 2009Co-Authors: C. S. Evans, R. W. GoyAbstract:The Social interactions of 12 adult Lemur catta were observed under standard conditions over a 20-month period. Descriptions of the Behavioural repertoire and of vaginal cytology throughout two breeding seasons provided the basis for a preliminary analysis of hormonal influences on Social Behaviour in a“lower”primate. Both long and short term fluctuations in gonadal activity were associated with changes in the frequency of expression of several non-sexual patterns, particularly of the species-characteristic and sexually differentiated displays of males. The latter appear to be predominantly olfactory gestures and serve to distribute skin-gland secretions, thereby integrating much Social activity. In contrast to the extended receptivity characteristic of some monkeys and apes, mating in the Ring-tail is restricted to a brief period during the 51/2-week cycle, being invariably coincident with vaginal oestrus. Hormonal factors alone are probably sufficient to determine the appearance of full Behavioural oestrus. Patterns (other than fighting) tentatively associated with territoriality and/or dominance appear the least sensitive to influence by gonadal secretions.

criminalizing sociability through anti Social Behaviour legislation dispersal powers young people and the police
Youth Justice, 2009Co-Authors: Adam CrawfordAbstract:This article explores the impact of dispersal powers introduced as part of the British government's drive to tackle anti-Social Behaviour. It focuses especially on the experiences and views of young people affected by dispersal orders. It highlights the importance of experiences of respect and procedural justice for the manner in which they respond to directions to disperse. It considers the ways in which dispersal powers can increase police—youth antagonism; bring young people to police attention on the basis of the company they keep; render young people more vulnerable; and reinforce a perception of young people as a riskto others rather than asat riskthemselves. It reflects on broader conceptions of youth and public space apparent within the anti-Social Behaviour agenda.

dispersal powers and the symbolic role of anti Social Behaviour legislation
Modern Law Review, 2008Co-Authors: Adam CrawfordAbstract:This article considers the development and use of dispersal powers, introduced by the Anti-Social Behaviour Act 2003, and situates these within the context of wider legislation and policy initiatives. It explores the ways in which the powers have been interpreted by the courts and implemented by police and local authorities. The article critically analyses the manner in which the powers: introduce ‘public perceptions’ as a justification for police encroachments on civil liberties; conform to a hybrid-type prohibition; constitute a form of preventive exclusion that seeks to govern future Behaviour; are part of a wider trend towards discretionary and summary justice; and potentially criminalise young people on the basis of the anxieties that groups congregating in public places may generate amongst others. It is argued that the significance of dispersal orders derives as much from the symbolic messages and communicative properties they express, as from their instrumental capacity to regulate Behaviour.

the quail genome insights into Social Behaviour seasonal biology and infectious disease response
BMC Biology, 2020Co-Authors: Katrina M Morris, David Gourichon, Simon Boitard, David W Burt, Angela Danner, Lel Eory, Heather L Forrest, Jerome Gros, Matthew HindleAbstract:The Japanese quail (Coturnix japonica) is a popular domestic poultry species and an increasingly significant model species in avian developmental, Behavioural and disease research. We have produced a high-quality quail genome sequence, spanning 0.93 Gb assigned to 33 chromosomes. In terms of contiguity, assembly statistics, gene content and chromosomal organisation, the quail genome shows high similarity to the chicken genome. We demonstrate the utility of this genome through three diverse applications. First, we identify selection signatures and candidate genes associated with Social Behaviour in the quail genome, an important agricultural and domestication trait. Second, we investigate the effects and interaction of photoperiod and temperature on the transcriptome of the quail medial basal hypothalamus, revealing key mechanisms of photoperiodism. Finally, we investigate the response of quail to H5N1 influenza infection. In quail lung, many critical immune genes and pathways were downregulated after H5N1 infection, and this may be key to the susceptibility of quail to H5N1. We have produced a high-quality genome of the quail which will facilitate further studies into diverse research questions using the quail as a model avian species.

sociometric status and Social Behaviour of children with and without learning difficulties
Journal of Child Psychology and Psychiatry, 1993Co-Authors: Dabie Nabuzoka, Pete SmithAbstract:Abstract—The sociometric status and Behaviour of 179 children aged 8 0-12.0 years,including 36 children with learning disabilities, were examined Compared to non-LDchildren, more LD children were rejected and fewer were popular LD children werenominated as shy, seeking help and as victims of bullying significzintly more than non-LDchildren, fewer were nominated as cooperative or as a leader. Aggressive Behaviours didnot distinguish the two groups. Teacher scores of LD children's Behaviour were not relatedto peer nominations, although those of non-LD children were Findings are discussed inrelation to the role of Social cognitive deficits in LD children's relationships with peers.Keywords Sociometric status, Social Behaviour, learning disabilities IntroductionChildren with learning disabilities (LD) in integrated settings tend to experienceproblems in peer relationships. They receive fewer positive and more negativenominations from classmates than their non-disabled counterparts and tend to havelower Social status (Bryan, 1974; MacMillan & Morrison, 1984; Taylor, Asher W Bruininks, 1978; Garrett & Crump, 1980). Mainstreamed mildlyintellectually disabled children report significantly more dissatisfaction and anxietyabout their peer relations than their normally developing classmates (Taylor et al,1987).Why should this be so? Gottlieb (1981) suggested that Behavioural differencesbetween disabled and non-disabled children, visible in integrated settings, contributeto this. For example, some studies report a high level of aggressive and disruptiveBehaviour in children with learning or intellectual disabilities (Forster, DeLawyer& Guevremont, 1985; McConaughy & Ritter, 1986).
