Vacant land conversion to community gardens: influences on generalist arthropod predators and biocontrol services in urban greenspaces

Due to economic decline and the recent rise in home foreclosure, many U.S. cities are faced with managing large acreages of vacant land. Interest in local food production on this land has the potential to dramatically reshape the composition of greenspace found within urban landscapes. This study examined how the conversion of vacant land to urban gardens and farms influenced arthropod generalist predator populations and their ability to support biocontrol services. We found that the abundance of Coccinellidae and Syrphidae, and the activity density of Carabidae, Formicidae, and Lycosidae were equivalent among vacant lot and urban garden sites. Dolichopodidae abundance and the activity density of Linyphiidae and Opiliones were reduced in urban gardens whereas Anthocoridae abundance and the activity density of Staphylinidae were greater within urban gardens relative to vacant lots. The biocontrol service supplied by generalist predators was measured using sentinel eggs (Helicoverpa zea (Noctuiidae)) and pupae (Sarcophaga bullata (Sarcophagidae) and Musca domestica (Muscidae)). We found no difference in the biocontrol of H. zea eggs or M. domestica pupae among the focal greenspaces. We found no difference in the removal of S. bullata pupae by predators in June 2010, whereas in August 2010 a greater proportion of pupae were removed in urban garden sites relative to vacant lots. Based on these findings, we discuss the potential of the urban landscape to support generalist predators and sustainable urban gardening and farming.     

A comparison of widowhood and well-being among older Greek and British-Australian migrant women

The impact of widowhood on well-being has been well-documented, but to date has not focused extensively on the experience of older migrants who have aged in a foreign land. This study aimed to examine the well-being of older migrant widows from two groups in South Australia: British-born (n = 61) and Greek-born (n = 60) Australian migrants, who had been widowed, on average, 13 years. All participants completed a self-report questionnaire in their preferred language. Three indicators of current well-being (self-rated health, depression and loneliness) as well as variables expected to differ cross-culturally, and potentially influence well-being (mourning rituals; continuing bonds to one's spouse; religiosity; social support) were measured. Greek-born widows displayed higher levels of mourning rituals, continuing bonds and religiosity than the British. Both groups perceived similarly high levels of familial social support. Greek widows also reported worse self-rated health, and increased symptoms of depression and loneliness compared to the British. This paper suggests that the detrimental impact of widowhood on well-being may be greater for non-English speaking migrants who are ageing outside of their country of origin, and who, despite residing in an English-speaking host country for several decades, have retained the linguistic, cultural and religious practices and traditions of their home country.     

Hogging the road

This essay examines how aesthetic, corporate and cultural formations have radically altered. motorcycling and its image over the past two decades as a means to highlight more general changes in cultural politics, citizenship and governing through culture. The essay begins with the Guggenheim's The Art of the Motorcycle exhibit, treated. as a means for shaping and governing thought and conduct about and on motorcycles. The essay then addresses numerous articulations between aesthetic criteria and economic practices that have benefited. corporate and professional entities at the expense of long-time motorcyclists. Lastly, the essay formulates genealogical criteria for assessing attempts to represent culture in the hopes of more actively engaging in struggles over not just representation, but the activation of modes of thought, conduct and citizenship.     

Courtship abuse and aggression: Contextual aspects

On the basis of previously unreported findings from Laner and Thompson's (1982) study of courtship violence, hypotheses derived from the literature on marriage, family, and spousal violence have been tested and compared with findings of two other recently published studies (Cate et al., 1982; Makepeace, 1981). Contextual aspects studied involve (1) alcohol and drug use in conjunction with violent premarital encounters; (2) the perceived mutuality/unilaterality of abusive and aggressive events; (3) the private/public aspect of courtship violence and perceptions of intervention attempts by witnesses; and (4) perceived causes of courtship violence. Findings indicate that spousal violence and violence at intimate, committed levels of courtship share a common explanatory framework. Suggestions for further research are offered.     

BECOMING HONG KONG,RAZING BAOAN,PRESERVING XIN'AN: AN ETHNOGRAPHIC ACCOUNT OF URBANIZATION IN THE SHENZHEN SPECIAL ECONOMIC ZONE

Located just north of Hong Kong, Shenzhen, the largest and oldest of China's Special Economic Zone (SEZ) has been both a project and symbol of post-Mao modernization. In this paper, I trace how the Shenzhen built environment mediates images and experiences of ‘Hong Kong’, arguing that transnationality in the SEZ is an everyday practice where tradition, colonialism, and the Cold War provide raw materials for the local reworking of the changing relationship between the Chinese state apparatus and finance capital. My story has a double focus: the ideology of urbanization as modernization and historic preservation. On the one hand, the ideology of urbanization-as-modernization legitimates a spatial order in which the rural is always posed to be superseded by the urban. Both the rural and the urban are empty signifiers that are created through comparison and deployed to guide action. In this important sense,‘Hong Kong’ has been urban with respect to rural ‘Shenzhen’ (formerly Baoan County), even as ‘Shenzhen’ has been urban with respect to the Chinese hinterland (neidi). On the other hand, historic preservation domesticates ‘Hong Kong’ as Shenzhen's past through the figure of Xin'an County, the geographic predecessor of both Shenzhen and Hong Kong. These complimentary displacements produce a nostalgia peculiar to the SEZ: a desire for a past that entitles contemporary Shenzhen residents to Hong Kong's prosperity. This nostalgia is structured with reference to a shared origin - Xin'an County - where Hong Kong's postwar history (1950–1979) becomes the past that Shenzhen (rural Baoan) would have had, if not for a cruel twist of socialist fate.     

Empowering Community-Based Programs for Youth Development

This article discusses the need for community-based programs for youth and their families and urges the social work profession to resume its historical leadership in such programs while incorporating recent theory and practice. The authors describe the reasons why social workers abandoned neighborhood-based youth development services, the intended outcomes of such services, and current societal and professional trends that support a revival of social work’s involvement in youth development. They discuss one school of social work’s current participation in a youth agency partnership and examine implications of the suggested revival for social work education. Collaboration among families, schools, diverse community services, agencies, and educators is emphasized.     

Aging with HIV: Historical and Intra-Community Differences in Experience of Aging with HIV

Gay men living with HIV/AIDS face a complex of health issues, including those associated with the aging process, long-term HIV infection (25 years or more), and side effects from Highly Active Anti-Retroviral Therapy (HAART). If aging can increase marginalization, this is more likely for the aging HIV positive gay man, who is already marginalized for being queer and living with a stigmatizing disease. This article presents findings from a study of a long-running HIV support group. It locates the members, all gay men living with HIV, in a specific historical and political context to explore how feelings of loss and the struggle to sustain community affect long-term survivors and other older HIV+ gay men. We identify specific challenges presented by aging for men who contracted HIV early in the epidemic, contrasting them with those faced by men infected with the virus later in life. While both groups appear to struggle with a vision of what life could have been, had AIDS not forced loss and change, they also celebrate the community their shared plight has enabled.
