Mammal conservation in a changing world: can urban gardens play a role?

Urbanisation threatens biodiversity globally, yet some animal populations persist within urban landscapes. Conservation of urban wildlife has prioritised parks and remnant bushland as critical habitat and neglected the role that residential gardens offer for conservation. We explored the potential for residential gardens to assist the conservation of mammals using an online questionnaire administered to residents of two case study cities in Australia to identify how widespread mammals in cities can be, which garden features promote mammal presence, and if the features varied among species with different habitat requirements. From 649 responses we found that three mammal species with different habitat requirements occurred in residential gardens throughout the city landscape. Garden features promoting mammal presence were consistent with broad ecological and habitat requirements of each species, but differed among both species and regions. Our study demonstrates that residential gardens offer a valuable habitat for mammals, and that garden features could be manipulated to promote use of gardens by these species. By considering gardens in urban planning and management actions aimed at conserving urban wildlife, residential gardens offer additional habitat to parks, roadside vegetation and urban bushland, and can play a significant role in biodiversity conservation.

     

Ecological regression analysis of environmental benzene exposure and childhood leukaemia: sensitivity to data inaccuracies, geographical scale and ecological bias

Benzene is classified as a group 1 human carcinogen by the International Agency for Research on Cancer, and it is now accepted that occupational exposure is associated with an increased risk of various leukaemias. However, occupational exposure accounts for less than 1% of all benzene exposures, the major sources being cigarette smoking and vehicle exhaust emissions. Whether such low level exposures to environmental benzene are also associated with the risk of leukaemia is currently not known. In this study, we investigate the relationship between benzene emissions arising from outdoor sources (predominantly road traffic and petrol stations) and the incidence of childhood leukaemia in Greater London. An ecological design was used because of the rarity of the disease, the difficulty of obtaining individual level measurements of benzene exposure and the availability of data. However, some methodological difficulties were encountered, including problems of case registration errors, the choice of geographical areas for analysis, exposure measurement errors and ecological bias. We use a Bayesian hierarchical modelling framework to address these issues, and we investigate the sensitivity of our inference to various modelling assumptions.     

Mothers' Cognitions about Relational Aggression: Associations with Discipline Responses, Children's Normative Beliefs, and Peer Competence

Prior research has shown that parental social cognitions are associated with child outcomes such as aggression. The goal of this study was to examine mothers' cognitions about relational aggression, and to explore linkages between mothers' attributions and normative beliefs about aggression and children's competence with peers. Participants included 103 mothers and children in grades 3 through 6. Results showed that mothers viewed relational aggression as more acceptable and normative than physical aggression, and they attributed less responsibility to children for using relational aggression. Maternal cognitions also predicted levels of sternness and disapproval in response to child relational aggression, and children's beliefs about the acceptability of relational aggression, which were associated with children's teacher-rated peer competence. Sex differences in the patterns of associations between maternal cognitions, discipline responses, child norms and peer competence were found. Applications of these results to parent education programs that are focused on relational aggression are discussed.     

Evaluation of an employee assistance program at a transportation company

The purpose of this study was to determine the effectiveness of an Employee Assistance Program (EAP) in terms of selected work performance indicators and treatment outcomes. Three primary data sources were utilized: a questionnaire administered to EAP users, reports from EAP counsellors on treatment diagnoses and outcomes, and employee records on absenteeism and other performance criteria over a five year time period. On the whole, EAP clients reported very favourable outcomes regarding the quality of services and improved well being, and the counsellors reported successful treatment outcomes. However, employee records on performance outcomes indicated that EAP clients had higher rates of problems before, during and after treatment, compared to a matched control group. Additionally, rates of sick days significantly increased from before to after treatment among EAP users.     

Beyond alphabet soup: helping college health professionals understand sexual fluidity

ABSTRACT

Many college students today are no longer using the terms straight, gay, lesbian, bisexual, or transgender to self-identify their sexual orientation or gender identity. This commentary explores research related to fluidity of sexual identities, emerging sexual identities used by college students, and how these identities interact with the health and well-being of the student. Additionally, the authors discuss strategies to help college health professionals provide a sensitive environment and clinical experience for students whose sexual identity is fluid.     

Teaching Note—Tweeting Macro Practice: Social Media in the Social Work Classroom

ABSTRACT

Despite its ubiquity, social work educators are just beginning to harness social media in teaching. In this teaching note, we discuss our use of Twitter in a bachelor’s-level macro Human Behavior in the Social Environment course. We present results from a survey of 45 students designed to assess their perceptions of Twitter use in the classroom and, in particular, as a macro social work learning tool. Students appreciated using social media in the course and reported that Twitter was a valuable professional social work tool. We explore how social work educators can provide an innovative classroom experience that incorporates ethical and professional use of social media and demonstrate how we used Twitter to apply macro practice competencies.     

Employing People With Disabilities: A Preliminary Assessment of a Start-Up Initiative

A major city in Pennsylvania initiated the Career Transition Liaison Project, the first of its kind in the region. Based on a mixed method evaluation design, the pilot study findings show that employing youth with disabilities requires certain accommodations and an initial investment in training, but these investments pay off for the employer.
