Social organization of marine Tucuxi dolphins, Sotalia guianensis, in the Cananeia Estuary of southeastern Brazil

Social organization is an important component of the population biology of a species that influences gene flow, the spatial pattern and scale of movements, and the effects of predation or exploitation by humans. An important element of social structure in mammals is group fidelity, which can be quantified through association indices. To describe the social organization of marine tucuxi dolphins (Sotalia guianensis) found in the Cananeia estuary, southeastern Brazil, association indices were applied to photo-identification data to characterize the temporal stability of relationships among members of this population. Eighty-seven days of fieldwork were conducted from May 2000 to July 2003, resulting in direct observations of 374 distinct groups. A total of 138 dolphins were identified on 1-38 distinct field days. Lone dolphins were rarely seen, whereas groups were composed of up to 60 individuals (mean +/- 1 SD = 12.4 +/- 11.4 individuals per group). A total of 29,327 photographs were analyzed, of which 6,312 (21.5%) were considered useful for identifying individuals. Half-weight and simple ratio indices were used to investigate associations among S. guianensis as revealed by the entire data set, data from the core study site, and data from groups composed of <= 10 individuals. Monte Carlo methods indicated that only 3 (9.3%) of 32 association matrices differed significantly from expectations based on random association. Thus, our study suggests that stable associations are not characteristic of S. guianensis in the Cananeia estuary.

The game of contacts: Estimating the social visibility of groups

Estimating the sizes of hard-to-count populations is a challenging and important problem that occurs frequently in social science, public health, and public policy. This problem is particularly pressing in HIV/AIDS research because estimates of the sizes of the most at-risk populations-illicit drug users, men who have sex with men, and sex workers-are needed for designing, evaluating, and funding programs to curb the spread of the disease. A promising new approach in this area is the network scale-up method, which uses information about the personal networks of respondents to make population size estimates. However, if the target population has low social visibility, as is likely to be the case in HIV/AIDS research, scale-up estimates will be too low. In this paper we develop a game-like activity that we call the game of contacts in order to estimate the social visibility of groups, and report results from a study of heavy drug users in Curitiba, Brazil (n = 294). The game produced estimates of social visibility that were consistent with qualitative expectations but of surprising magnitude. Further, a number of checks suggest that the data are high-quality. While motivated by the specific problem of population size estimation, our method could be used by researchers more broadly and adds to long-standing efforts to combine the richness of social network analysis with the power and scale of sample surveys.

The social construction of child maltreatment: the role of medical practitioners

• Summary: This paper explores how medical knowledge in child protection practice operates, in conjunction with social work knowledge and legal knowledge, as a social process of constructing meaning as ‘maltreatment’ (or not) in which the physical body of the child and perceived abnormalities represent ‘evidence’. Through discourse analysis of two case studies, this paper makes explicit and problematizes the social processes by which meanings are given by medical practitioners, social workers, police and parents to material experiences, the preference given to some meanings over others, and the econsequences of particular meanings for children and families and social work practice.

• Findings: Medical, social and legal knowledge are not neutral but embedded in power relations. The case studies show, through a sociological analysis of professional practice in child protection, how preferred versions of knowledge and meaning may override or dismiss alternative meanings, with particular consequences for parents and children and for practice outcomes.

• Applications: The case studies offer opportunities by which critically to engage with child protection knowledge, policy and practice in keeping with contemporary approaches that advocate dialogue, critical reflection and reflexivity, so that professional knowledge and professional power may be deployed constructively rather than oppressively.

The social validity of interventions for promoting preschool childrens peer interactions

This analogue study investigated the social validity of classroom interventions designed to promote peer interactions in young children. The influences of child characteristics and diagnostic labels on social validity ratings were examined, as were the relationships among three components of social validity. Forty-two preschool teachers completed a 15-item social validity scale that yielded scores pertaining to intervention goals, procedures and effects. Participants rated three types of intervention, which varied according to individuals targeted and intensity of programming procedures, with reference to one of three case descriptions of children with social interaction problems. Half the participants were provided with the child’s diagnostic label. Results indicated that social validity is affected by interactions between intervention methods and child characteristics. The inclusion of diagnostic labels in the case descriptions had no effect on social validity ratings. Strong positive relationships were found among the components of social validity. Implications for the use of empirically validated interventions in inclusive preschools are discussed.

The several social constructions of James, Jenks, and Prout: A contribution to the sociological theorization of childhood

The article is intended to contribute to the ongoing debate over theorizations of childhood, especially in the terms articulated by Allison James, Chris Jenkins and Alan Prout. The article focuses on the notion of social construction as a theory of childhood. There are four valid approaches to theorizing childhood. The tribal approach treats childhood as a kind of exotic tribe with its own beliefs, practices and institutions. The social structural approach treats childhood as a structurally necessary stratum in any society. The minority group approach treats childhood as an oppressed minority group, able to some extent to represent themselves and exert quasi-political action. The socially constructed approach constitutes the sociological view of childhood. The key role played by the idea of social construction is made extremely clear in the earlier work, Constructing and Reconstructing Childhood by James and Prout. Social constructionism is said to be an interpretive approach, related historically to research on children's understanding of adult experimenters' intentions. The senses of social construction that emerge from critical psychology overlap a great deal with those articulated in the new sociology of childhood.

Corporate social responsibility of small businesses: a developing country perspective

Corporate social responsibility (CSR) has emerged as an important concept for developing countries in recent years. This paper investigates the issues of CSR relating to small businesses that have emerged as a result of market-based reforms in developing countries, where the compliance of voluntary standards, code of conduct and regulations are limited. The paper argues that prevalence of corruption, lack of rule based governance, resource constraints for effective capacity building on the part of the state and lack of awareness have created a weak and unethical corporate culture leading to low levels of CSR in developing countries. Using Bangladesh agriculture sector as an exemplar, this paper investigates how small businesses trading in agricultural inputs with no brand capital and low public visibility are behaving in a socially irresponsible way, in an environment of inadequate regulatory sanctions and compliance by selling contaminated inputs to farmers who are mostly poor and not even aware of their rights. The low levels of CSR is undermining and also threatening the sustainability of the positive impact of the market-based reforms undertaken in this sector. The paper proposes that integrated governance linking state, private sector and civil society can promote good governance and better CSR relating to small businesses .

Structural deficiency or cultural racism: the educational and social experiences of Arab-Australian youth

This paper discusses the cultural, attitudinal and structural factors that impact upon the social experiences and educational achievements of Arabic-speaking background (ASB) students in three Melbourne secondary schools with high levels of cultural and linguistic diversity. The paper makes the case for and then outlines a multidimensional approach to multicultural education to better integrate ASB students and their families into the schooling environment. Key strategies developed and tested include a model of school-community partnership, online and interactive teacher support material (TSM) as well as on-going teacher professional development workshops on reflexive approaches to cultural diversity and intercultural tension.

The social consequences of 'how the sibling died' for bereaved young adults

Research into how the 'type' of sibling death impacts surviving siblings at a social level was conducted using a semi-structured interview format with 25 bereaved siblings and seven counsellors. The results indicated that in cases where a sibling's death had a greater impact within public spheres, the young adult was more likely to receive beneficial social support than young adults associated with 'private' death examples. The paper concludes by outlining how individuals can provide effective support for bereaved young adults, as well as avoid unhelpful support behaviours.
