Use of subpopulation data in Australian forensic DNA casework

DNA profiling evidence presented in court should be accompanied by a reliable estimate of its evidential weight. In calculating such statistics, allele frequencies from commonly employed autosomal microsatellite loci are required. These allele frequencies should be collected at a level that appropriately represents the genetic diversity that exists in the population. Typically this occurs at broadly defined bio-geographic categories, such as Caucasian or Asian. Datasets are commonly administered at the jurisdictional level. This paper focuses on Australian jurisdictions and assesses whether this current practice is appropriate for Aboriginal Australian and Caucasian populations alike. In keeping with other studies we observe negligible differences between Caucasian populations within Australia when segregated geographically. However segregation of Aboriginal Australian population data along contemporary State and Territory lines appears to mask the diversity that exists within this subpopulation. For this reason datasets collated along more traditional lines may be more appropriate, particularly to distinguish the most genetically differentiated populations residing in the north of the continent.     

Infighting and Ideology: How Conflict Informs the Local Culture of the Chicago Dyke March

Although the study of local cultures has become established in American sociology, it often ignores the contested nature of how culture emerges and is negotiated within the context of small groups. To this end, we address the concept of infighting, a subtype of conflict, as it operates within a small group framework. Building on an ethnographic study of the Chicago Dyke March, we demonstrate that infighting highlights competing ideologies that may remain implicit in the absence of such conflict. Infighting treats divergent meaning systems as part of local contention between rival cliques and power centers. These ideological battles both reflect pre-existing differences between subgroups and serve to make explicit and public such differences, both in their background characteristics and in their interests. In the process infighting directs attention away from shared concerns and group building to questions of strategy, transforming the small group into an arena of ideological production and factional rivalry. Infighting recasts a group from a space of consensus to a contested political arena. We elaborate four analytic processes through which infighting connects to ideology and small group culture: infighting emphasizes the multivocality of meaning, cultural heterogeneity, an equilibrium of inclusion and group boundaries, and planning in light of ideologies of power.     

The impact of police charges in incidents of wife abuse

The present study addressed the impact of an urban police force laying criminal charges in cases of wife abuse. Follow-up data from battered women and from police officers were collected to identify the long-term consequences of this police policy that began in 1981, including any negative or unintended side effects. Results indicated that the policy resulted in a dramatic increase in police-laid charges (2500%), and a shift from the Family to the Criminal Division of Provincial Court. Based on interview data, victims did not decrease their requests for police service (a feared side effect) and reported a significantly higher level of satisfaction with police service in this area. A significant reduction in police calls and victim-reported violence was associated with police intervention, especially when charges were laid. Paradoxically, police officers' attitudes about the policy were more negative than the actual positive changes that they helped to produce. Considerations for future research and professional training are outlined.
