Emerging dragonfly diversity at small Rhode Island (U.S.A.) wetlands along an urbanization gradient

Natal habitat use by dragonflies was assessed on an urban to rural land-use gradient at a set of 21 wetlands, during two emergence seasons (2004, 2005). The wetlands were characterized for urbanization level by using the first factor from a principal components analysis combining chloride concentration in the wetland and percent forest in the surrounding buffer zone. Measurements of species diversity and its components (species richness and evenness) were analyzed and compared along the urbanization gradient, as were distributions of individual species. Dragonfly diversity, species richness, and evenness did not change along the urbanization gradient, so urban wetlands served as natal habitat for numerous dragonfly species. However, several individual species displayed strong relationships to the degree of urbanization, and most were more commonly found at urban sites and at sites with fish. In contrast, relatively rare species were generally found at the rural end of the gradient. These results suggest that urban wetlands can play important roles as dragonfly habitat and in dragonfly conservation efforts, but that conservation of rural wetlands is also important for some dragonfly species.     

Eventful Subjectivity: The Experiential Sources of Solidarity

Scholarship on events has been devoted primarily to large‐scale occurrences that transform macro structures. Here we put forward a perspective that we term eventful subjectivity which moves the analysis of events in two related directions. First, we shift the arena of eventful analysis from rare world historical occurrences to smaller, more frequent events. Second, we direct attention away from macro‐structural outcomes to micro‐level changes in understanding. We employ the framework of eventful subjectivity to examine a living wage campaign in Chicago, demonstrating how the multi‐faceted diversity of the campaign – in the context of collective action – engendered solidarity rather than fragmentation.     

Rise and Fall of Sleep Quantity and Quality With Student Experiences Across the First Year of University

Covariations of self‐reported sleep quantity (duration) and quality (disturbances) with affective, stressful, academic, and social experiences across the first year of university in 187 Canadian students (M age=18.4) were examined with multilevel models. Female students reported sleeping fewer hours on average than did male students. In months when negative affect and general levels of stress were higher, sleep quantity was lower. Poorer sleep quality was seen in students living away from home and reporting more financial stress at baseline. In addition, sleep quality was poorer in months when negative affect and general levels of stress were higher (attenuating the effect of financial stress) and better in months when students spent more days with friends. Three themes are presented to explore the mechanisms by which sleep quantity and quality rise and fall in tandem with experiences of the first year of university.     

Profiles of adult survivors of severe sexual,physical and emotional institutional abuse in Ireland

Adult survivors of institutional abuse were interviewed with a comprehensive assessment protocol which included the Childhood Trauma Questionnaire, the Institutional Child Abuse Processes and Coping Inventory, the Structured Clinical Interviews for Disorders of the Diagnostic and Statistical Manual of Mental Disorders IV axis I disorders and personality disorders, the Trauma Symptoms Inventory, a Life Problems Checklist, the Experiences in Close Relationships Inventory and the Kansas Marital Satisfaction Scale. Profiles were identified for subgroups that described severe sexual (N = 60), physical (N = 102), or emotional (N = 85) abuse as their worst forms of maltreatment. Survivors of severe sexual abuse had the most abnormal profile, which was characterised by higher rates of all forms of child maltreatment and higher rates of post‐traumatic stress disorder, alcohol and substance abuse, antisocial personality disorder, trauma symptoms and life problems. Survivors of severe emotional abuse were better adjusted than the other two groups. The profile of survivors of severe physical abuse occupied an intermediate position between the other two groups. A thorough assessment of abuse history and current functioning should be conducted when providing services to adult survivors of institutional abuse, since this may have important implications for the intensity of services required. Survivors of severe sexual abuse may require more intensive services. Copyright © 2009 John Wiley & Sons, Ltd.
