Improvement in measures of psychological distress amongst amphetamine misusers treated with brief cognitive-behavioural therapy (CBT)

This trial of cognitive-behavioural therapy (CBT) based amphetamine abstinence program (n = 507) focused on refusal self-efficacy, improved coping, improved problem solving and planning for relapse prevention. Measures included the Severity of Dependence Scale (SDS), the General Health Questionnaire-28 (GHQ-28) and Amphetamine Refusal Self-Efficacy. Psychiatric case identification (caseness) across the four GHQ-28 sub-scales was compared with Australian normative data. Almost 90% were amphetamine-dependent (SDS 8.15 +/- 3.17). Pretreatment, all GHQ-28 sub-scale measures were below reported Australian population values. Caseness was substantially higher than Australian normative values {Somatic Symptoms (52.3%), Anxiety (68%), Social Dysfunction (46.5%) and Depression (33.7%). One hundred and sixty-eight subjects (33%) completed and reported program abstinence. Program completers reported improvement across all GHQ-28 sub-scales Somatic Symptoms (p < 0.001), Anxiety (p < 0.001), Social Dysfunction (p < 0.001) and Depression (p < 0.001)}. They also reported improvement in amphetamine refusal self-efficacy (p < 0.001). Improvement remained significant following intention-to-treat analyses, imputing baseline data for subjects that withdrew from the program. The GHQ-28 sub-scales, Amphetamine Refusal Self-Efficacy Questionnaire and the SDS successfully predicted treatment compliance through a discriminant analysis function (p

Predictors of osteoarthritis(OA) improvement in patients treated with Hylan G-F for knee OA.

Aim of study: Different criteria for treatment response were explored to identify predictors of OA improvement. Analyses were based on data from a previously reported 1-year randomized controlled trial of appropriate care with or without hylan G-F 20 in patients with knee OA. Methods: Five definitions of ‘‘patient responder’’ from baseline to month 12 were examined: at least 20% reduction in WOMAC pain score; at least 20% reduction in WOMAC pain score and at least 20% reduction in either the WOMAC stiffness or function score; OARSI responder criteria (Propositions A and B) for intra-articular drugs; and OMERACT-OARSI responder criteria (Proposition D). As an a posteriori analysis, multivariable logistic regression models for each definition of patient responder were developed using a forward selection method. The following variables were defined prior to modeling and considered in the model along with two-way interactions: age (O65 years), BMI, gender, X-ray grade (0, I, II vs III, IV), co-morbidity (1 or 2 conditions vs 3 or more), duration of OA in study knee (years), previous surgery of study knee, hylan G-F 20 injection technique, WOMAC pain, stiffness and function, and treatment group. Results: Hylan G-F 20 was a predictor of improvement for all patient responder definitions P ! 0.001; odds of improvement were 2.7 or higher for patients in the hylan G-F 20 group compared to appropriate care without hylan G-F 20. For three of the five patient responder definitions, X-ray grade was a predictor of improvement (P ! 0.10; lower X-ray grade increased the odds of improvement). For four of the five patient responder definitions, duration of OA was a predictor of improvement (P ! 0.10; shorter duration of OA increased the odds of improvement). Conclusion: Analyses showed that appropriate care with hylan G-F 20 is the dominant predictor of patient improvement. While high grade structural damage does not preclude a response, patients who are targeted early in the disease process when less structural damage has occurred, may have a greater chance of improvement.

Curriculum development for professional ethics in Australian human service university programmes

Australian academics and practitioners in the human services are particularly susceptible to social, political and economic influences in respect of their relevance, viability and operations. In fact, it can be argued that the impact of these influences has placed human service practitioners and academics in a perpetual state of vulnerability. Australian universities have been challenged to make their programmes more relevant and viable to the community at large, and practitioners face increasing workloads with limited resources based on restricted fiscal allocation, and the changing relationship between government and service providers. Drawing on interview data from twenty-one (n = 21) practitioners, this article highlights their identified problems regarding the notion of professionalism in the human services with a particular focus on ethical dilemmas in human service practice. Gleaning these details will be a basis for recommending necessary professionalethics curricula content in human services programmes offered in Australian universities. Moreover, while the research data is Australian based, the authors contend that the universal theories and principles underpinning human service practice justify the significance and value of the data as an important source for international consideration in curriculum development of human service academic programmes.

Lucerne biology and genetic improvement - an analysis of past activities and future goals in Australia

Breeding methodologies for cultivated lucerne (Medicago sativa L.), an autotetraploid, have changed little over the last 50 years, with reliance on polycross methods and recurrent phenotypic selection. There has been, however, an increase in our understanding of lucerne biology, in particular the genetic relationships between members of the M. sativa complex, as deduced by DNA analysis. Also, the differences in breeding behaviour and vigour of diploids versus autotetraploids, and the underlying genetic causes, are discussed in relation to lucerne improvement. Medicago falcata, a member of the M. sativa complex, has contributed substantially to lucerne improvement in North America, and its diverse genetics would appear to have been under-utilised in Australian programs over the last two decades, despite the reduced need for tolerance to freezing injury in Australian environments. Breeding of lucerne in Australia only commenced on a large scale in 1977, driven by an urgent need to introgress aphid resistance into adapted backgrounds. The release in the early 1980s of lucernes with multiple pest and disease resistance (aphids, Phytophthora, Colletotrichum) had a significant effect on increasing lucerne productivity and persistence in eastern Australia, with yield increases under high disease pressure of up to 300% being recorded over the predominant Australian cultivar, up to 1977, Hunter River. Since that period, irrigated lucerne yields have plateaued, highlighting the need to identify breeding objectives, technologies, and the germplasm that will create new opportunities for increasing performance. This review discusses major goals for lucerne improvement programs in Australia, and provides indications of the germplasm sources and technologies that are likely to deliver the desired outcomes.

Emotion in the workplace: The new challenge for managers

Emotions in workplace settings and emotional intelligence are hot topics in management today. Leading business journals such as Fortune and Harvard Business Review have featured articles on emotional intelligence. But there is more to emotions in the workplace than just emotional intelligence. The aim of this article is to acquaint managers with intriguing new research that examines both emotional intelligence and the broader issue of emotion, which has been shown to play a powerful role in workplace settings. We show that this research has a strong potential for practical application in organizations within many broad human-resource functions such as selection, performance management, and training, as well as implications for more narrow domains like customer service. We conclude that the study of emotions in organizational settings has provided new and important insights into the way in which people in organizations behave, and we offer advice for managers to enable them to develop and to maintain a positive emotional climate in their organizations.

Telephone counselling for adolescent suicide prevention: Changes in suicidality and mental state from beginning to end of a counselling session

Telephone counselling is an accessible and confidential means by which distressed young people can seek help. Telephone counselling services were funded under Australia's National Youth Suicide Prevention Strategy between 1997 and 2000. In this study, the effectiveness of telephone counselling for young people seeking help in the context of suicidal ideation or intent was evaluated in an investigation of calls made by suicidal young people to a telephone counselling service. Independent raters measured callers' suicidality and mental state at the beginning and, end of 100 taped counselling sessions. Changes in suicidality and mental state were measured using a reliable rating scale developed for the study. Significant decreases in suicidality and significant improvement in mental state were found to occur during the course of counselling sessions, suggesting positive immediate impact.-Limitations of the study with respect to longer-term outcomes and the relevance of the results for suicide prevention are discussed. Notwithstanding the study limitations, the results lend support for continuing development of hotline services.

Partnerships in mental health: Addressing barriers to social inclusion

Current trends in mental health services emphasize working in partnership with consumers and other government and non-government community organizations for improvement in quality of life for service users. People with a mental illness experience social exclusion, thereby limiting their ability to participate fully in community life. Occupational therapists have a substantial role to play in helping service users to overcome barriers to their community inclusion. Partnerships need to be formed to increase access to community resources and participation in activities that are enjoyed by other members of the community. Such partnerships have a health promotion emphasis and foster the relationship between mental-health services and the wider community, thus shifting the focus from direct occupational therapy service delivery to community-based rehabilitation interventions.This article describes the development, implementation and evaluation of an Australian healthy lifestyle course devised to meet the identified rehabilitation goals of people with mental illness to lose weight, get fit, commence vocational study and get a job. The course was run in partnership between mental health consumers, occupational therapists from the St George Mental Health Rehabilitation Service and staff and students from the Sutherland College of Technical and Further Education.

Analysis of service stress corrosion cracking in a natural gas transmission pipeline, active or dormant?

Stress corrosion cracks (SCC) had been found in a natural gas transmission pipeline during a dig-up and inspection program. The question was raised as to whether the SCC was active or dormant. This paper describes the resultant investigation to determine if a particular service crack was actively growing. The strategy adopted was to assess the appearance of the fracture surface of the service crack and to compare with expectations from laboratory specimens with active SCC. The conclusions from this study are as follows. To judge whether a crack in the service pipe is active or dormant, it is reasonable to compare the very crack tip of the service crack and a fresh crack in a laboratory sample. If the crack tip of the active laboratory sample is similar to that of the service pipe, it means the crack in the service pipe is likely to be active. From the comparison of the crack tip between the service pipe and the laboratory samples, it appears likely that the cracks in the samples extracted from service were most likely to have been active intergranular stress corrosion cracks.
