National survey of occupational therapy managers in mental health

This study, part of the College of Occupational Therapists' Mental Health Project, surveyed occupational therapy managers in mental health to gather data about them, the services they managed and their opinions on current and future issues of importance. A questionnaire was sent to the 184 managers who it was believed worked in mental health and it achieved a 65.2% response rate. The majority of the 120 respondents were female, with Head II therapists between the ages of 31 and 40 forming the largest group. Two-thirds had additional qualifications and 71% had worked in mental health for more than 11 years. In addition to managing occupational therapy services, 86% carried a caseload or managed other services. Aspects of professional management were ranked highest in a list of tasks undertaken. Contradictions were noted in the managers' opinions on recruitment and retention of staff and the importance of staff supervision. The managers displayed commitment to the principles and philosophy of occupational therapy and a determination to demonstrate its effectiveness through research and evidence-based practice. This study contributed to the position paper on the way ahead for occupational therapy in mental health (Craik et al 1998a) and provided information for occupational therapy managers to assist them to review their role

College of occupational therapists: Position paper on the way ahead for research, education and practice in mental health

The future of occupational therapy in mental health has been a topic of reflection and debate. The Education and Research Board (now the Education and Practice Board) of the College of Occupational Therapists created a Working Group to develop a position paper on the way ahead for research, education and practice in mental health. Following consultation, the Working Group reviewed literature, examined current research and surveyed practitioners, managers and educators. From these findings, recommendations have been made which will lead to a firmer evidence base for the practice of occupational therapy in mental health, leading to a more effective use of the expertise of occupational therapists and an improved service for users

Hydroxyl Damage in Silica: Full-range description including large damages

When water diffuses into silica glass it reacts chemically with the glass forming nanometre sized pores that change the physical properties of the glass. In earlier papers and reports, we discussed the effect of water/silica reaction on the strength via volume swelling, and showed by use of damage mechanics that the water reaction reduces Young’s modulus E and intrinsic strength in thin surface layers. In this paper, the dependency between hydroxyl concentration and damage will be derived for the full damage range by using experimental results from literature. For small water concentrations, we used sound velocity measurements from literature. The suggested relations describe the dependence between the hydroxyl concentration and the Young’s modulus for the damaged glass and allow the strength decrease due to hydroxyl generation to be computed. From an example of application, it can be concluded that damage by hydroxyl generation has little effect on strength even in the case of completely damaged surface region so far the water-affected surface zone is much thinner than the bulk material

Mass Transfer of Water at Silica Surfaces - Extension of the data base to lower temperatures

In two previous reports we have dealt with the description of the time dependence of the water content at the surface of silicate glass by mass transfer (SWP 73 and SWP 94). Literature measurements in the range of 200°C100°C. Measurements by Helmich&Rauch serve as a basis. A step change in the mass transfer coefficient is found at 200°

Crack-tip models by Irwin and Dugdale for hydroxyl-damaged crack-tip zones

Due to the hydroxyl generation, the silica network ahead of crack tips is damaged. The consequence is a damaged crack-tip zone showing a reduced Young’s modulus. The linear-elastic fracture mechanical treatment by application of stress intensity factors becomes doubtful especially for large zones. In this report, we use a description via well-known models of Elastic-Plastic Fracture Mechanics, namely, the models by Irwin and Dugdale. As an application we compared the results with experimental observations on crack profiles from literature. The computed and observed Crack-Tip Opening Displacements (CTOD) were found to be in good agreement

Validation of the swelling formalism via evaluation of bending moments from literature: Comparison of theoretical predictions and measurements

The volume of silica expands by the hydroxyl generation when silica surfaces react with water. These volume strains are proportional to the mass concentration of the hydroxyl. They were measured by Wiederhorn et al. by evaluating the curvature of disks undergoing this reaction on only one side. The obtained bending moments were found to be proportional to square-root of heat-treatment time. In the present considerations we pay particular attention to global bending moments caused by swelling, which, in contrast to local swelling stresses, do not require assumptions about the type of stress distribution. It can be stated that • The bending moments from disk curvature and hydroxyl measurements via the IR-evaluation procedure by Libowitzky and Rossman are in excellent agreement. • Predictions of moments M based on diffusivities and surface water concentrations by Helmich and Rauch also show good agreement with correlation coefficients R$^2$>0.95. Consequently, we can sufficiently write: M$_{predict}$ = M$_{measured}$

Monitoring the Vernal Advancement and Retrogradation (Green Wave Effect) of Natural Vegetation

The author has identified the following significant results. The Great Plains Corridor rangeland project successfully utilized natural vegetation systems as phenological indicators of seasonal development and climatic effects upon regional growth conditions. An effective method was developed for quantitative measurement of vegetation conditions, including green biomass estimates, recorded in bands 5 and 6, corrected for sun angle, were used to compute a ratio parameter (TV16) which is shown to be highly correlated with green biomass and vegatation moisture content. Analyses results of ERTS-1 digital data and correlated ground data are summarized. Attention was given to analyzing weather influences and test site variables on vegetation condition measurements with ERTS-1 data
