OBJECTIVE: To compare existing community treatments for post-partum depression (PPD), treatment efficacy was evaluated for 146 women seeking treatment for PPD in the local community. METHODS: Self-report questionnaires were designed to assess clinical depression and anxiety (psychological and physiological), risk factors, treatment satisfaction and the impact of social supports. RESULTS: Comparison of treated subjects with those on a wait-list demonstrated that depression and the psychological component of anxiety decreased significantly after treatment. Psychological and pharmacological interventions produced similar clinical benefit in the treatment of psychological symptoms, and receiving both treatments in combination was of no added clinical benefit in the immediate or longer term. Individual treatment was associated with more rapid treatment gains initially than group treatment. However, the benefits of group treatment emerged during the 6 months following treatment, leading both interventions to be equally effective in the longer term. Cognitive behavioural therapy was not superior to the combination of non-specific counselling or behavioural strategies, either immediately following treatment or 6 months later. CONCLUSIONS: Clinical efficacy together with other clinical and financial benefits strongly advocate the application of psychological treatment for PPD. Clear parallels between PPD and general depression support the application of knowledge about general depression to extend understanding of PPD and refine clinical management practices.
A new growth subroutine was developed for CERES-Wheat, a computer model of wheat (Triticum aestivum) growth and development. The new subroutine simulates canopy photosynthetic response to CO2 concentrations and light levels, and includes the effects of temperature on canopy light-use efficiency. Its performance was compared to the original CERES-Wheat V-2 10 in 30 different cases. Biomass and yield predictions of the two models were well correlated (correlation coefficient r > 0.95). As an application, summer growth of spring wheat was simulated at one site. Modeled crop responses to higher mean temperatures, different amounts of minimum and maximum warming, and doubled CO2 concentrations were compared to observations. The importance of irrigation and nitrogen fertilization in modulating the wheat crop climatic responses were also analyzed. Specifically, in agreement with observations, rainfed crops were found to be more sensitive to CO2 increases than irrigated ones. On the other hand, low nitrogen applications depressed the ability of the wheat crop to respond positively to CO2 increases. In general, the positive effects of high CO2 on grain yield were found to be almost completely counterbalanced by the negative effects of high temperatures. Depending on how temperature minima and maxima were increased, yield changes averaged across management practices ranged from -4% to 8%.
BACKGROUND: Vulvar melanoma is a very rare form of cancer. The purpose of this study was to describe practice patterns for the management of vulvar melanoma. STUDY DESIGN: The National Cancer Data Base was reviewed from 1985 through 1994 for patient reports submitted with a diagnosis of vulvar melanoma. RESULTS: Five hundred sixty-nine patients with vulvar melanoma were identified. A substantial number of patients were older; during the latter period of this study (1990 to 1994), 50% were 70 years old or older. Surgery was used in more than 90% of patients with stages 0 to III. Local excision was used mainly in early-stage (0 and I) disease. Adjuvant therapy was used infrequently. Lymph node evaluation was performed in more than half of the patients, with greater frequency for patients who had advanced disease. The overall 5-year relative survival rate was 62%. If the lymph nodes contained metastases, survival was poor. Patients with recurrent disease also had poor survival. CONCLUSIONS: Surgery remains the mainstay of therapy for vulvar melanoma. The use of excision and radical operations remained constant during the 10 years of the study.

In a follow-up survey to a 1984 study, 339 paediatricians in Australia were invited to complete a brief questionnaire in 1990, in which they indicated their usual recommendations, practices and advice when managing children with Down syndrome. The response rate was 67%. The results indicated that the most frequent paediatrician-initiated referrals were for early intervention and for discussion with other parents; these options were selected more frequently in 1990 than in 1984. While referral to a social worker was the next most frequent choice, it occurred less in 1990 than in 1984. Other increases in referrals were for physiotherapy and speech therapy. Paediatricians were more likely to support referral to a geneticist, speech therapist or cosmetic surgeon in response to a specific parental enquiry, and less likely to support referral to a social worker or to full-time care. There had been significant increases since 1984 in the likelihood that paediatricians would order audiology and investigation of thyroid and cardiac function. There was less opposition to the use of sedatives, and virtual cessation of the use of tryptophan. Paediatricians were more optimistic about the likelihood of persons with Down syndrome living independently, caring for their own finances, and marrying, but not about other developmental areas.

The purpose of this article is to explore top management's perceptions of how various human resources management (HRM) practices changed in hospitals (n = 101) after union elections. Significant increases in many HRM practices that are believed to lead to competitive advantage through human resources were reported in firms in which unions lost elections but not in firms where unions were certified.
