Practice theory for clinical social work

It is suggested that practice theory for clinical social work practice is in a state of disarray. Six new books on clinical social work practice are reviewed, with an identification of their contributions to the development of clinical practice theory. The expanded societal functions of clinical social work have resulted in major changes in method and in practice activities, without commensurate development of appropriate theory, as about environmental-situational interventions. Good theoretical advances have been made, as about a basic ecological systems model, though with need for a greater openness to new theories and to an eclectic approach. Advances have also been made in clinical research and knowledge building, handicapped though this may be by current critical inadequacies in the professional schools, particularly in the continued resistance to the development of clinical doctorate programs.

Exposure Assessment: Methods of Analysis for Environmental Carcinogens1

Human populations are exposed to environmental carcinogens in both indoor and outdoor atmospheres. Recent studies indicate that pollutant concentrations are generally higher in indoor atmospheres than in outdoor. Environmental pollutants that occur in indoor air from a variety of sources include radon, asbestos, organic and inorganic compounds, and certain particles (e.g., tobacco smoke). Some of the gases or vapors are adsorbed on suspended particulate matter, whereas others exist entirely in the gas phase or are distributed between the latter and a particle-bound state. Because of differences in chemical and physical properties, each class of carcinogens generally requires different sampling and analytical methods. In addition, a single indoor environment may contain a wide variety of air pollutants from different sources. Unfortunately, no single best approach currently exists for the quantitative determination of such complex mixtures and, for practical reasons, only the more toxic or the more abundant pollutants are usually measured. This paper summarizes the currently available monitoring methods for selected environmental pollutants found in indoor atmospheres. In addition, some possible sources for those pollutants are identified.     

Reasons for Seeking Help for a Gambling Problem: The Experiences of Gamblers Who Have Sought Specialist Assistance and the Perceptions of Those Who Have Not

This paper presents reasons for help-seeking data as reported by users of a national gambling helpline (help-seekers, HS, n = 125) as well as data pertaining to perceived reasons for seeking help as reported by gamblers recruited from the general population (non-help-seekers, NHS, n = 104). All data were collected via a structured, multi-modal survey. Participants in both groups considered help-seeking to be motivated by multiple factors (mean of 6.8 and 10.6 responses, respectively). Responses indicative of financial concern were most frequently reported by both HS and NHS participants (82 & 90%, respectively). Over a third of HS participants (35%) also identified financial concern as their primary reason for seeking help and 50% of NHS participants perceived financial concern to be the primary motivator for seeking help in a problem gambling context. Common types of secondary influence (other than financial concern) included psychological distress (HS & NHS participants), problem prevention (HS participants), rational thought (HS participants), physical health issues (HS participants), and relationship issues (NHS participants). The implications for promoting greater or earlier help-seeking activity amongst problem gamblers are discussed.

Gambling Participation,Expenditure and Risk of Harm in Australia, 1997–1998 and 2010–2011

Gambling-related harm results primarily from financial losses. Internationally Australia continues to rank as the largest spending nation per capita on gambling products. This would suggest that Australian gamblers are at disproportionately high risk of harm despite almost two decades of industry scrutiny and regulation, and investment in research, treatment and education programs. However, declines in participation rates, per capita expenditure, household expenditure, national disposable income spent on gambling and problem gambling rates have been cited as evidence that fewer people are gambling, that gamblers are spending less, and that gambling safety in Australia has improved. The current study investigated these propositions using national population and accounts data, and statistics from Australia’s two population-representative gambling surveys conducted in 1997–1998 and 2010–2011. Despite a falling participation rate the study found no real change in the number of people gambling overall, and increasing numbers consuming casino table games, race wagering and sports betting. Further found were increases rather than decreases in average gambler expenditure, overall, and across most products, particularly electronic gaming machines (EGMs). Potentially risky levels of average expenditure were observed in both periods, overall and for race wagering, casino table gaming, and EGMs. Changes in the proportion of income spent on gambling suggest risks declined overall and for race wagering and casino table gaming, but increased for EGMs. Finally, while problem gambling statistics were not comparable between periods, the study found double the number of moderate risk gamblers previously estimated for 2010–2011 amongst the 2 million Australians found to have experienced one or more gambling-related problems. The findings have implications for public health policy and resourcing, and the way in which prevalence and expenditure statistics have been interpreted by researchers, government and industry in Australia and elsewhere.     

Effektive Führung heterogener Teams

This article in the journal “Gruppe. Organisation. Interaktion. (GIO)” analyzes theoretical and empirical findings of international research on the role of leadership in diverse teams. While practitioners often tend to expect primarily positive effects of team diversity, research has revealed both positive and negative consequences on team performance. Thereby, realizing positive outcomes of diversity appears to depend on additional boundary conditions; among these, leadership is often considered to be crucial. According to our analysis of the literature, established leadership styles (e.?g., transformational leadership, LMX, leader consideration) may contribute to increased performance of diverse teams. In addition, they will be most effective when leaders perceive and treat their followers as individuals rather than as members of a (sub-)group and when they carefully adjust their behavior to the most critical diversity attribute in the team. Based on these results, we provide practical implications for leadership in diverse teams and discuss how adequate leadership skills can be systematically developed in organizations.
