Urbanization affects the trophic structure of arboreal arthropod communities

Urbanization is one of the most significant causes of habitat fragmentation on the planet, resulting in substantial losses of biodiversity and disruptions to ecological processes. We examined the effects of urbanization on the diversity and abundance of arboreal invertebrates in a dominant tree species (Angophora costata) in a highly urbanized landscape in Sydney, Australia, identifying the potential ecological consequences of shifts in diversity. We hypothesized that trophic structure would be influenced by landscape context with a greater richness and abundance of invertebrates in small remnants and edges. Canopy arthropods were sampled via beating from trees in 15 sites in three landscape contexts; five large patches of continuous vegetation, five edges of large patches and five small urban remnants. Trees in large patches supported fewer individuals compared to trees in small urban remnants and edge sites. The composition of assemblages and overall trophic structure also differed between edges and large patches, with a greater abundance of grazing insects in edges. No differences were detected between small urban remnants and edges, suggesting that observed differences might be attributed to an edge effect as opposed to an area effect per se. These changes in trophic structure, revealing a greater abundance of grazing herbivores and a reduced abundance of predators and parasitoids in edge sites, are consistent with work describing elevated levels of herbivory in edges of remnant vegetation. Future management of remnant urban vegetation and associated biodiversity requires not only an understanding of how trophic status influences the extent of responses by arboreal invertebrate communities, but also how these will affect ecosystem functioning.     

CROSSOVER OF OCCUPATIONAL STRESS IN DUAL-CAREER COUPLES

This study considers the source, nature and direction of ‘crossover’ of occupational stressors and strains in a sample of 74 dual-career couples. It examines patterns and habits of discussion about work between partners and investigates the role of partner communication and job commitment in the crossover process. Contrary to previous research findings which suggest that the direction of crossover is predominantly from men to their female partners, positive relationships were found between women's work stressors and the anxiety and depression reported by their male partners. Only modest evidence of crossover from men to women was found. Work demands were linked to the crossover process for both men and women but, unlike the findings of previous studies, supportive features of the working environment failed to predict crossover between partners. The nature and frequency of marital communication about work was associated with crossover, as was job commitment and satisfaction. The implications of these findings for the psychological health and functioning of dual-career couples are discussed, and recommendations for future research that might further elucidate the crossover process are made.     

Welfare reforms in Canada

This study examines the development of impoverished pre-school children before and after the implementation of mandatory welfare-to-work initiatives in Canada. Using data from the 1994/95 and 1998/99 cycles of the National Longitudinal Survey of Children and Youth, we explore the relationships that impoverished families’ income source and family income status have with pre-school children's school readiness. Findings indicate that both before and after the implementation of mandatory welfare-to-work initiatives, children in working poor families had higher school readiness scores than their peers whose families receive social assisntance, independent of family environment characteristics that differentiated working poor and social assistance poor families. In addition, both before and after the implementation of mandatory welfare-to-work initiatives, school readiness scores of poor children were lower than scores for non-poor children, with children living in families that had incomes at least 200 percent of the low-income cut-offs being the only group with scores above the expected standard of 100. In sum, our study fails to provide evidence that by the end of the 1990s welfare reforms supported the concurrent policy goal of improving the well-being of Canadian children in poverty.     

Self-perceived occupational stress and distress in a Scottish police force

This paper describes an empirical study (n = 699) of occupational stress in a Scottish police force. The self-perceived stress associated with a variety of organizational and opearational stressors was examined along with the associated distress in the police officers in terms of symptoms of anxiety, somatic complaint, severe depression and social dysfunction. The analysis revealed that in spite of the potential that police work offers for exposure to adverse opeational situations such as violence or death, the highest levels of associated stress lie in relation to organizational factors such as officers' perceptions of staff shortages, inadequate resources, time pressures, lack of communication and work overload. Differential rates of perceived stress are reported accordng to gender, rank and working location. This paper further validates previsous research on stress in British police and addresses the situation from a Scottish perspective.     

Auditory–Visual Context and Memory Retrieval in 3‐Month‐Old Infants

In 3 experiments, 3‐month‐old infants were trained to move an overhead mobile by kicking 1 of their feet in the presence of a distinctive visual (crib bumpers) and auditory (music) context. In Experiment 1A, 5‐day but not 1‐day retention was disrupted if either or both elements of the context present during the retention test were novel. In Experiment 1B, 5‐day retention was observed when only a single component of the training context, visual or auditory, was present. In Experiment 2, the retention test occurred at 14 days but it was preceded 24 hr earlier by a brief reactivation treatment. When the reactivation treatment consisted of reexposing the infant to the training crib bumpers and music, or just to the training music, it was not successful. Reactivation was successful when the reactivation treatment consisted of only the training crib bumpers. These results indicate that, in this paradigm, 3‐month‐old infants do not encode the elements of the context holistically and that, following forgetting, the visual contextual cues become dominant over the auditory contextual cues in facilitating retrieval.     

From Freaks to Savants: disability and hegemony from The Hunchback of Notre Dame (1939) to Sling Blade (1997)

At the turn of the century the Protestant ethic combined with Victorian morality helped turn audiences away from 'Freaks Shows'. This act isolated the performers (who were generally labeled with a physical or mental disability) from not only the rest of society but also from the economy. However, images of people with disabilities did not disappear. The 'mainstream' film industry took over as chief exhibitors stigmatizing characters with disabilities as either violent psychotic offenders or child like savants. However, in 1932, Tod Browning resurrected the 'Freak Show' and made a remarkable film celebrating and starring actual performers from 'Freak Shows'. The film, Freaks , managed to 'normalize' the performers but was a box office and critical disaster. MGM banished the film to the vaults for twenty years, while in England it was banned for over forty. It is blamed for bringing Browning's career to an end and the stars were forced back into isolation. The purpose of this paper is to examine the criticism of Freaks by comparing and contrasting it with images of the more 'successful' mainstream films. Through this analysis I will demonstrate that the criticism for Freaks as it stands is unsupported. I argue what truly offends, shocks audiences and critics alike and the reason for the film's continued 'banishment' is not only the visibility of the actors with disabilities, but also the fact that Browning and his actors found no shame in showcasing their diversity. It is within both the criticism of the film and the mainstream films depicting characters with disabilities where the institutional rejection of diversity is found, not in the images Browning showcased.     

Sexual Harassment as an Exercise of Power

This article argues that the key to the explanation as to why sexual harassment is a feature of organizational life lies in the issue of power. Yet there has been little attempt to link sexual harassment with theories or explanatory models of power. This article first takes Lukes's (1986) three‐dimensional model as a framework to explore how harassment may be understood as an exercise of power at different levels then shows how radical feminist and post‐structuralist analyses overlap with and are distinct from Lukes's third dimension of power.     

A meta-ethnographic study of health care staff perceptions of the WHO/UNICEF Baby Friendly Health Initiative

BackgroundImplementation of the Baby Friendly Health Initiative (BFHI) is associated with increases in breastfeeding initiation and duration of exclusive breastfeeding and ‘any’ breastfeeding. However, implementation of the BFHI is challenging.AimTo identify and synthesise health care staff perceptions of the WHO/UNICEF BFHI and identify facilitators and barriers for implementation.MethodSeven qualitative studies, published between 2003 and 2013 were analysed using meta-ethnographic synthesis.FindingsThree overarching themes were identified. First the BFHI was viewed variously as a ‘desirable innovation or an unfriendly imposition’. Participants were passionate about supporting breastfeeding and improving consistency in the information provided. This view was juxtaposed against the belief that BFHI represents an imposition on women's choices, and is a costly exercise for little gain in breastfeeding rates. The second theme highlighted cultural and organisational constraints and obstacles to BFHI implementation including resource issues, entrenched staff practices and staff rationalisation of non-compliance. Theme three captured a level of optimism and enthusiasm amongst participants who could identify a dedicated and credible leader to lead the BFHI change process. Collaborative engagement with all key stakeholders was crucial.ConclusionsHealth care staff hold variant beliefs and attitudes towards BFHI, which can help or hinder the implementation process. The introduction of the BFHI at a local level requires detailed planning, extensive collaboration, and an enthusiastic and committed leader to drive the change process. This synthesis has highlighted the importance of thinking more creatively about the translation of this global policy into effective change at the local level.
