Trends in bird species richness,abundance and biomass along a tropical urbanization gradient

Impacts of urbanization on biodiversity are commonly studied using urbanization gradients which provide a space-for-time substitution in estimating consequences of urban expansion. Rates of urbanization and human population growth are high in tropical countries of the developing world, which also hold most of the world’s biodiversity hot-spots, yet few studies have considered biodiversity trends along urban gradients in these regions. Bird communities across a gradient of nine sites in Uganda, from the city centre of Kampala to outlying rural locations, were studied over a six year period. These sites were ordered along an urbanization gradient using Principle Components Analysis based on habitat variables estimated at each site. Bird species richness showed a decrease from rural to urban sites, a trend especially evident in forest birds. There was no clear pattern in total abundance, total biomass or biomass per individual along the gradient. However, this latter result was heavily influenced by a colony of Marabou Storks at one site. When this species was omitted, there was evidence of a positive trend with urbanization, showing that as species richness decreased, the bird community was increasingly dominated by larger species with increasing urbanization, which were mainly scavengers able to exploit human refuse. These results provide further support for the negative impacts of urbanization on species richness, but also demonstrate trends in abundance and biomass are variable across different regions. In particular, the increasing dominance of larger species in urban areas may be relevant to certain geographic and/or socioeconomic contexts.     

Defining social work leadership: a theoretical and conceptual review and analysis

With the recent increase in social work leadership literature, a few issues in research and practice have come to light. Social work research employs leadership theory derived from military leadership principles adjusted for application in corporate entities, which have decidedly different goals and processes than social work organisations. These models may be influencing the methods of social work leadership research such that study outcomes reflect business-based rather than human service processes and goals. A dearth of leadership education in social work schools and in professional social work settings contributes to a paucity of social workers in upper level administrative roles. A systematic theoretical literature review on social work leadership is conducted in order to generate a working definition of social work leadership and a series of multi-level social work leadership principles. Implications for future research and practice are discussed.     

Disparate Levels of Stress in Police and Correctional Officers: Preliminary Evidence from a Pilot Study on Domestic Violence

New data from a prevention curriculum project on officer-involved domestic violence reveals significant differences in the reported job stress of Florida's correctional officers when compared to police officers who took the same surveys. The significantly higher reported levels of organizational stress in particular—especially those related to staff and resource shortages and attitudes about leadership—raise concerns about the relationship between organizational stress and the reported drastic budget cuts, hiring freezes, and layoffs experienced by the Department of Corrections in 2009. The surprising disparity has significant implications for policy makers, who should be aware of the high cost of stress in officer health and well-being when making budgetary decisions about the state's rapidly increasing inmate population.     

Applying the Haddon Matrix to evaluate sexual assault interventions on college campuses

Abstract

Objective: A Haddon Matrix analysis was used to systematically review literature evaluating college campus sexual assault prevention programs to identify research gaps and intervention opportunities. Methods: Articles included were published from January 1, 2001 to December 31, 2017; indexed in PubMed, PsycInfo, or Scopus; involving English-speaking undergraduate students in the US; with experimental or quasi-experimental design. Results: All 31 eligible studies evaluated educational programing; all relied on self-report measures; and three-quarters had follow-up periods ≤ 6?months. Significant positive effects were reported by 6 of 10 studies that measured bystander behavior, 6 of 10 that educated potential victims and assessed victimization, and one of four that educated potential perpetrators and measured perpetration. Conclusion: The Haddon Matrix analysis identified the need for interventions that address perpetrators and the post-assault period, as well as studies of the impact of enforcing existing policies and new environmental and situational approaches to sexual assault prevention.     

Another Way of Talking About Substance Abuse: Substance Abuse Screening and Brief Intervention in a Mental Health Clinic

This article provides experiential evidence on the transportability of the Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST) screening tool and brief intervention in a mental health clinic. There is very little published information on implementing screening and brief intervention (SBI) in a mental health setting. Moreover, few SBI projects have reported on clinicians' experiences using the ASSIST. The article documents a successful attempt at implementing the ASSIST and discusses the benefits and challenges of doing SBI in a mental health setting.     

Some aspects of prostitution

This study was based on data collected from 87 men during and immediately following participation in a counseling program aimed at assisting them to reduce sexual behaviors associated with high HIV risk. All the men reported having engaged in same‐gender anal or oral sex without condoms during the year prior to enrollment. Three‐month retrospective reports of sexual behavior, solicited just after participation, were compared with reports collected weekly during the same three‐month period. Accuracy of recall over an ensemble of 10 behavior items was quite low, with amount of error positively associated with behavior frequency. In general, exaggerated reports were associated with low‐frequency behavior and underreports with high‐frequency behavior. Because of observed differences in the average frequency of occurrence of the various specific types of sexual behavior, adjustment for event frequency was required to provide adequate analysis of between‐behavior differences in memory error. Estimated functional relationships between behavior frequency and average memory error illustrated that for sexual activity occurring between 1 and 20 times in the three‐month period, there was a significant association between the HTV‐risk level of a behavior and the average extent to which the behavior was forgotten (i.e., underreported). After event‐frequency adjustment, anal activity without condoms—the behavior believed to entail the highest level of risk for HIV transmission, and the behavior about which the counseling program provided the least ambiguous cues regarding risk—was associated with the greatest underreporting error, and the ensemble of unprotected behaviors (i.e., those unaccompanied by condom usage) involved significantly greater underreporting than did protected behaviors. Error rates over the ensemble of behaviors were strikingly low for zero‐frequency events, suggesting the utility of dichotomous ever/never measures in research evaluating activity levels and behavior change. Other analysis techniques for reducing potential recall bias, allowing finer evaluations of behavior frequency and change, were also discussed.     

Postmodern feminism: a theoretical framework for a field unit with women in jail

This article presents a postmodern, feminist framework as a foundation for a social work student field unit with women inmates in the corrections system. Feminist pedagogical methods were developed and implemented for this field unit and, once trained, the students utilized feminist social work skills within the jail environment. The case study illustrates the field unit design, student learning processes, and examples of student interventions. In addition to becoming skillful clinicians, student interns became social change agents within the corrections system. Implications for micro, meso, and macro levels of social work practice are discussed.     

Obituary

Abstract

This article introduces the idea of social defence, which is nonviolent community resistance to aggression as an alternative to military defence. An outline is given of some connections between the grassroots orientation to social defence and strands within community development. A community research project on telecommunications is described to illustrate the possible connections that can be forged between social defence and community empowerment.
