Occupational therapy assessment of self-awareness following traumatic brain injury

Impaired self-awareness is a common problem following traumatic brain injury. Without adequate self-awareness, a person's motivation to participate in rehabilitation may be limited, which in turn can have an adverse effect on his or her functional outcome. For this reason, it is important that brain injury rehabilitation professionals, including occupational therapists, both understand this phenomenon and use assessment and treatment approaches aimed at improving clients' self-awareness. This article provides an overview of self-awareness, reviewing the distinction between intellectual and online awareness. The current role of occupational therapy in the assessment of self-awareness is highlighted and the guidelines for new assessments of self-awareness suitable for use in occupational therapy are explored.

Allowance for thermodynamic non-ideality in the characterization of protein self-association by frontal exclusion chromatography: hemoglobin revisited

This investigation re-examines theoretical aspects of the allowance for effects of thermodynamic non-ideality on the characterization of protein self-association by frontal exclusion chromatography, and thereby provides methods of analysis with greater thermodynamic rigor than those used previously. Their application is illustrated by reappraisal of published exclusion chromatography data for hemoglobin on the controlled-pore-glass matrix CPG-120. The equilibrium constant of 100/M that is obtained for dimerization of the (02 species by this means is also deduced from re-examination of published studies of concentrated hemoglobin solutions by osmotic pressure and sedimentation equilibrium methods.

Kinetic parameters associated with self-heating of New Zealand coals under adiabatic conditions

Adiabatic self-heating tests were carried out on five New Zealand coal samples ranging in rank from lignite to high-volatile bituminous. Kinetic parameters of oxidation were obtained front the self-heating curves assuming Arrhenius behaviour. The activation energy E (kJ mol(-1)) and the pre-exponential factor A (s(-1)) were determined in the temperature range of 70-140 degreesC. The activation energy exhibited a definite rank relationship with a minimum E of 55 kJ mol(-1) occurring at a Suggate rank of similar to6.2 corresponding to subbituminous C. Either side of this rank there was a noticeable increase in the activation energy indicating lower reactivity of the coal. A similar rank trend was also observed in the R-70 self-heating rate index values that were taken from the initial portion of the self-heating curve front 40 to 70 degreesC. From these results it is clear that the adiabatic method is capable of providing reliable kinetic parameters of coal oxidation.

Perceived stress as a predictor of the self-reported new diagnosis of symptomatic CHD in older women

This article describes one aspect of a prospective cohort study of 10,432 women aged between 70 and 75 years. After a 3-year period, 503 women self-reported a new diagnosis by a doctor of angina or myocardial infarction (symptomatic coronary heart disease [CHD]). Time one psychosocial variables (Duke Social Support Index, time pressure, Perceived Stress Scale, Mental Health Index, having a partner, educational attainment, and location of residence) were analyzed using univariate binary logistic regression for their ability to predict subsequent symptomatic CHD. Of these variables, the Duke Social Support Index, Perceived Stress Scale and the Mental Health Index were found to be significant predictors of symptomatic CHID diagnosis. Only the Perceived Stress Scale, however, proved to be a significant independent predictor. After controlling for time one nonpsychosocial variables, as well as the frequency of family doctor visits, perceived stress remained a significant predictor of the new diagnosis of symptomatic CHD in this cohort of older women over a 3-year period.

Radial Distortion Self-Calibration

In cameras with radial distortion, straight lines in space are in general mapped to curves in the image. Although epipolar geometry also gets distorted, there is a set of special epipolar lines that remain straight, namely those that go through the distortion center. By finding these straight epipolar lines in camera pairs we can obtain constraints on the distortion center(s) without any calibration object or plumbline assumptions in the scene. Although this holds for all radial distortion models we conceptually prove this idea using the division distortion model and the radial fundamental matrix which allow for a very simple closed form solution of the distortion center from two views (same distortion) or three views (different distortions). The non-iterative nature of our approach makes it immune to local minima and allows finding the distortion center also for cropped images or those where no good prior exists. Besides this, we give comprehensive relations between different undistortion models and discuss advantages and drawbacks.

Agronomic performance of 27 cocoa progenies and plant selection based on productivity, self-compatibility and disease resistance

The objective of the present work was to evaluate 27 progenies of cocoa crosses considering the agronomic traits and select F1 plants within superior crosses. The experiment was installed in March 2005, in the Experimental Station Joaquim Bahiana (ESJOB), in Itajuipe, Bahia. The area of the experiment is of approximately 3 ha, with a total of 3240 plants. Thirteen evaluations of vegetative brooms, five of cushion brooms and 15 of number of pods per plant were accomplished. Thirty pollinations were made for each selected plant to test for self-compatibility. The production, based on the number of pods per plant, and resistance to witches´ broom indicated CEPEC 94 x CCN 10, RB 39 x CCN 51 and CCN 10 x VB 1151 as superior progenies. All selections tested were self-compatible. The analyses of progenies and individual tree data, associated to visual field observations, allowed the selection of 17 plants which were included in a network of regional tests to determine the phenotypic stability.

Da criação de uma Ordem Profissional

O objetivo central deste estudo é a análise da perspetiva dos Assistentes Sociais sobre a necessidade/ importância da criação de uma Ordem Profissional e, consequentemente de um Código Deontológico (português) para a profissão. Privilegiou-se a investigação qualitativa, construída a partir da interpretação das narrativas das entrevistas, da pesquisa bibliografia e documental. O carácter qualitativo do trabalho concretiza-se por meio de uma lógica abdutiva, que pretende compreender a realidade através da construção dos seus atores (Blaikie, 2000). Para o efeito construímos duas dimensões de análise: a primeira refere-se à análise e compreensão da necessidade de criação de uma Ordem Profissional e a segunda dimensão integra a análise da opinião dos informantes sobre a necessidade de criação de um código deontológico português. Os resultados obtidos nesta investigação demonstram de forma unânime, a importância da criação de uma Ordem Profissional para a legitimação, representatividade e autorregulação da categoria profissional. Nas razões apontadas para a importância da Ordem surgem, quer justificações que se centram na necessidade de uniformização da prática, demonstrando uma visão mais burocrática e tecnicista da profissão, no qual os métodos se sobrepõem à relação, quer razões de legitimação e de necessidade de representação coletiva junto à classe política, relacionada com uma vertente humanista, no qual os aspetos relacionais e comportamentais devem fazer parte da prática profissional de forma a uma maior adequação dos mecanismos de intervenção no indivíduo. Nas razões apontadas para o insucesso da não criação de uma Ordem Profissional, a maioria realçou motivos internos e externos inerentes à profissão. A questão interna tem a ver com a falta de associativismo e união dos Assistentes Sociais em se mobilizarem por uma causa comum. A questão externa relaciona-se com interesses políticos, bem como a questão coletiva dos profissionais. Os princípios subjacentes a um código deontológico são os inerentes aos direitos humanos e justiça social e de atitudes associadas à profissão.

How middle managers contribute to strategy formation process: connection of strategy processes and strategy practices

The role of middle management is essential when managing integrative and emergent strategy formation processes. We stand out the importance of its role connecting micro and macro organizational level offering a very important contribution when examining the strategy-as-practice perspective and integrative strategy formation process. The main goal of this research is to analyse the relationship between the integrative strategy formation process and the roles of middle management under the strategy-as-practice perspective. To check it out we adopted a qualitative methodology droving a case analysis in a Spanish University. Data was collected by means of personal interviews with members of different levels of the Institution, documents analysis and direct observation. In advance of some results we find out that the University develops an integrative strategy formation process and confers to middle management an important role extended all over the organization.

Analysis of mediation and reciprocal effects of changes in weight, self-esteem, and exercise in a behavioral weight loss treatment

Improving the treatment of obesity remains a critical challenge. Several health behaviour change models, often based on a social-cognitive framework, have been used to design weight management interventions (Baranowski et al., 2003). However, most interventions have only produced modest weight reductions (Wadden et al., 2002) and socialcognitive variables have shown limited power to predict weight outcomes (Palmeira et al., 2007). Other predictors, and possibl alte nati e e planatory models, are needed to better understand the mechanisms by which weight loss and other obesity treatment-outcomes are brought about (Baranowski, 2006). Self-esteem is one of these possible mechanisms, because is commonly reported to change during the treatment, although these changes are not necessarily associated with weight loss (Blaine et al., 2007; Maciejewski et al., 2005). This possibility should be more evident if the program integrates regular exercise, as it promotes improvements in subjective well-being (Biddle & Mutrie, 2001), with possible influences on long-term behavioral adherence (e.g. diet, exercise). Following the reciprocal effects model tenets (Marsh & Craven, 2006), we expect that the influences between changes in weight, selfesteem and exercise to be reciprocal and might present one of the mechanisms by which obesity treatments can be improved.
