Different Social Contexts (different + social_context)
Selected AbstractsForaging Behaviour of Subordinate Great Tits (Parus major).ETHOLOGY, Issue 10 2001Can Morphology Reduce the Cost of Subordination? This paper studies the magnitude of the behavioural shift, from forage standing to forage hanging, of subordinate great tits (Parus major) in two different social contexts: feeding solitarily vs. feeding with a dominant conspecific. The aim is to test the hypothesis that differences in morphological design provide subordinates with varying abilities to reduce the presumed costs of subordination. We find that different subordinate individuals change the foraging behaviour, occupying a different niche when an intra-specific competitor is present. Morphology linked to sexual dimorphism, specifically body mass, is the factor responsible for the different magnitudes of change. Lighter subordinates can remain longer than heavier ones at the feeding patch without interrupting their foraging. Thereby, the former reduce the costs of being subordinate more than the latter. Among subordinates, females are lighter than males; they also spend more time feeding in the presence of a dominant conspecific than males do. No differences are found between age categories. We find no relationship between tarsus length and individual ecological plasticity. Our results support the idea that the ecological plasticity due to morphological differences is a mechanism that allows subordinate individuals to overcome costs associated with subordination. [source] The Social Networks of People with Intellectual Disability Living in the Community 12 Years after Resettlement from Long-Stay HospitalsJOURNAL OF APPLIED RESEARCH IN INTELLECTUAL DISABILITIES, Issue 4 2006Rachel Forrester-Jones Background, The social inclusion of people with intellectual disabilities presents a major challenge to services. As part of a 12-year follow up of people resettled from long-stay hospitals, the size of 213 individuals' social networks and the types of social support they received were investigated, as viewed by people with intellectual disabilities themselves. The types of support received in four different kinds of community accommodation were compared. Method, Individuals were interviewed and their social support networks mapped using a Social Network Guide developed for the study. Descriptive statistics were generated and comparisons made using generalized linear modelling. Results, The sample comprised 117 men (average age 51 years) and 96 women (average age 56 years). All but seven were White British, 92% were single and they had in general, mild to moderate intellectual disabilities. The average network size was 22 members (range 3,51). The mean density was 0.5. A quarter of all network members were other service users with intellectual disabilities and a further 43% were staff. Only a third of the members were unrelated to learning disability services. In general, the main providers of both emotional and practical support were staff, although these relationships were less likely to be described as reciprocal. Other people with intellectual disabilities were the second most frequent providers of all types of support. People in small group homes, hostels and supported accommodation were significantly more likely to report close and companiable relationships than those in residential and nursing homes, but they also reported a greater proportion of critical behaviour. Conclusions, The social networks revealed in this study are considerably larger than those of previous studies which have relied on staff reports, but findings about the generally limited social integration of people with intellectual disabilities are similar. A clearer policy and practice focus on the desirability of a range of different social contexts from which to derive potentially supportive network members is required so that people do not remain segregated in one area of life. [source] Is there a place for individual subjectivity within a social constructionist epistemology?JOURNAL OF FAMILY THERAPY, Issue 4 2010Sim Roy-Chowdhury The epistemological turn towards social constructionism has become well established within the field of family systemic therapy. Social constructionism has provided therapists with a theoretical rationale for the concentration upon the social context within which individuals and families live their lives. This is a philosophical position that pushes to the margins the positivist premise that individuals have fixed and measurable personalities in favour of a discourse which proposes that the person is encountered differently within different social contexts. Prompted by the growing interest in systemic practice with individuals and by the rediscovery of the psychoanalytic canon within family therapy literature, the adequacy of this position is examined and an attempt is made to open up a space within social constructionist discourse for a theory of individual subjectivity. Findings from a research project are the starting point for this venture. These findings are understood through the lens of psychoanalytic theory, with particular reference to the work of Jacques Lacan. [source] Variation in Reproductive Behaviour within a Sex:Neural Systems and Endocrine ActivationJOURNAL OF NEUROENDOCRINOLOGY, Issue 7 2002T. Rhen Abstract Intrasexual variation in reproductive behaviour, morphology and physiology is taxonomically widespread in vertebrates, and is as biologically and ecologically significant as the differences between the sexes. In this review, we examine the diverse patterns of intrasexual variation in reproductive behaviours within vertebrates. By illustrating the genetic, cellular, hormonal and/or neural mechanisms underlying behavioural variation in a number of species, another level of complexity is added to studies of brain organization and function. Such information increases our understanding of the unique and conserved mechanisms underlying sex and individual differences in behaviour in vertebrates as a whole. Here, we show that intrasexual variation in behaviour may be discrete or continuous in nature. Moreover, this variation may be due to polymorphism at a single genetic locus or many loci, or may even be the result of phenotypic plasticity. Phenotypic plasticity simply refers to cases where a single genotype (or individual) can produce (or display) different phenotypes. Defined in this way, plasticity subsumes many different types of behavioural variation. For example, some behavioural phenotypes are established by environmental factors during early ontogeny, others are the result of developmental transitions from one phenotype early in life to another later in life, and still other strategies are facultative with different behaviours displayed in different social contexts. [source] The communicative content of the common marmoset phee call during antiphonal callingAMERICAN JOURNAL OF PRIMATOLOGY, Issue 11 2010Cory T. Miller Abstract Vocalizations are a dominant means of communication for numerous species, including nonhuman primates. These acoustic signals are encoded with a rich array of information available to signal receivers that can be used to guide species-typical behaviors. In this study, we examined the communicative content of common marmoset phee calls, the species-typical long distance contact call, during antiphonal calling. This call type has a relatively stereotyped acoustic structure, consisting of a series of long tonal pulses. Analyses revealed that calls could be reliably classified based on the individual identity and social group of the caller. Our analyses did not, however, correctly classify phee calls recorded under different social contexts, although differences were evident along individual acoustic parameters. Further tests of antiphonal calling interactions showed that spontaneously produced phee calls differ from antiphonal phee calls in their peak and end frequency, which may be functionally significant. Overall, this study shows that the marmoset phee call has a rich communicative content encoded in its acoustic structure available to conspecifics during antiphonal calling exchanges. Am. J.

[source] Time course of vocal modulation during isolation in common marmosets (Callithrix jacchus)AMERICAN JOURNAL OF PRIMATOLOGY, Issue 8 2010Chieko Yamaguchi Abstract Common marmosets vocalize phee calls as isolation calls, which seem to facilitate their reunion with family groups. To identify multiple acoustic properties with different time courses, we examined acoustic modulations of phees during different social contexts of isolation. Subject marmosets were totally isolated in one condition, were visually isolated and could exchange vocalizations in another condition, and were visually isolated and subsequently totally isolated in a third condition. We recorded 6,035 phees of 10 male,female marmoset pairs and conducted acoustic analysis. The marmosets frequently vocalized phees that were temporally elongated and louder during isolation, with varying time courses of these changes in acoustic parameters. The vocal rates and sound levels of the phees increased as soon as the marmosets saw their pair mates being taken away, and then gradually calmed down. The phee duration was longer in conditions during which there were no vocal responses from their pair mates. Louder vocalizations are conspicuous and seem to be effective for long-distance transmission, whereas shorter call duration during vocal exchanges might avoid possible vocal overlap between mates.

[source] Social Functioning and Adjustment in Chinese Children: The Imprint of Historical TimeCHILD DEVELOPMENT, Issue 1 2005Xinyin Chen This study examined, in 3 cohorts (1990, 1998, and 2002) of elementary school children (M age=10 years), relations between social functioning and adjustment in different phases of the societal transition in China. Data were obtained from multiple sources. The results indicate that sociability-cooperation was associated with peer acceptance and teacher-rated competence, whereas aggression was associated with social and school difficulties in all 3 cohorts. The effect of different social contexts was reflected mainly in the relations between shyness-sensitivity and adjustment. Whereas shyness was associated with social and academic achievement in the 1990 cohort, the associations became weaker or nonsignificant in the 1998 cohort. Furthermore, shyness was associated with peer rejection, school problems, and depression in the 2002 cohort. [source] | |||||||||||||
