Associations of Quality of Life,Physical Activity and Mood States in Women with Breast Cancer Treated with Curative Intent

This study aims to investigate the associations between quality of life, physical activity and mood states in women with breast cancer. A total of 354 women (mean age, 51.74?±?8.63 years; body mass index (BMI), 28?±?5.67 kg/m²) completed the Baecke Physical Activity Questionnaire, Profile of Mood States (POMS), European Organisation for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) and European Organisation for Research and Treatment of Cancer Breast Cancer-Specific Quality of Life Questionnaire (EORTC QLQ-BR23). Pearson’s correlation and multiple linear regressions were used to verify the relations between outcomes and independent variables. Correlations between scores on POMS, Baecke Physical Activity Questionnaire and global health status/quality of life subscale of EORTC QLQ-C30 found associations (p?<?0.01) between physical activity (r?=?0.191), vigour (r?=?0.333) and fatigue (r?=??0.433). Multiple linear regression analysis of the global health status/quality of life subscale of the EORTC QLQ-C30 showed significant differences for vigour (p?<?0.001), social function (p?=?0.003), side effects of systemic therapy (p?=?0.019), arm and breast symptoms (p?<?0.001) and Baecke physical activity score (p?=?0.006). Physical activity is an independent factor related to the quality of life in women with breast cancer. Understanding these variables may influence clinical decisions during treatment and allow positive interventions regarding symptoms, functions and lifestyle.     

Life Design Counseling: A study on client's operations for meaning construction

This study evaluated the adequacy of the micro-theory of client operations to explain meaning construction during Life Design Counseling. Four adolescents were interviewed about their second counseling session. Their recollections were stimulated through the replay of counseling videotapes. The resulting transcribed interviews were qualitatively analyzed. Results confirmed a sequence of client operations evolving from the symbolic representation of experience and reflexive self-examination towards making new realizations and revisioning self. Moreover, clients reported negative and positive session moments evidencing that clients' attention and activity during the session was not restricted to meaning construction operations. Practical implications for life design counseling are derived from the results and discussed.     

The multiple-stimulus-without-replacement preference assessment tool and its predictive validity

This study demonstrates the use of two web-based programs, one to identify video preferences and the other to assess their reinforcing effects. We used the Multiple-Stimulus-Without-Replacement Preference Assessment Tool (MSWO PAT) to identify the video preference hierarchies of seven participants, ages 4–11 years old. We then used a customized reinforcer assessment program that arranged a concurrent-chains preparation with programmed conjugate schedules of reinforcement. Button presses emitted by participants modulated the quality (volume and opacity) of selected videos on a moment-to-moment basis, allowing us to identify the reinforcing effects of the videos in little time. The results showed that the preference assessment had predictive value for five of seven participants. We discuss the MSWO PAT, parameters that may affect the identification of preferences and the use of conjugate schedules to identify reinforcers.

Development of disruptive behaviors in young children: A prospective population‐based cohort study

We know relatively little about the development of disruptive behaviors (DBs), and gender differences therein. The objective of this study was to describe the continuity and discontinuity in the degree to which young children in the general population are reported to exhibit specific DBs over time. Data came from the Québec Longitudinal Study of Child Development. First, the results show that relatively few children exhibit DBs on a frequent basis at 41 months of age. Second, the results show that a majority of children who exhibit a particular DB on a frequent basis at 41 months of age did not do so 1 year earlier. In addition, a majority of children who exhibited a particular DB on a frequent basis at 29 months of age no longer do so 1 year later. Third, gender differences in DBs (boys > girls) are either emerging or at least increasing in magnitude between 29 and 41 months of age. Consistent with the canalization of the behavioral development principle, children who exhibited DBs on a frequent basis at 29 months of age are less likely to stop doing so in the following year if they had exhibited the same behaviors at 17 months of age.     

Forced treadmill exercise prevents oxidative stress and memory deficits following chronic cerebral hypoperfusion in the rat

Physical activity impacts functional recovery following stroke in humans, however its effects in experimental animals submitted to chronic cerebral hypoperfusion have not been investigated. The aim of this study was to evaluate the therapeutic potential of exercise, as assessed by cognitive activity in the Morris water maze and the brain oxidative status, through measurement of macromolecules damage, TBARS levels and total cellular thiols, as well as antioxidant enzymes in hippocampus, striatum and cerebral cortex. Adult male Wistar rats were submitted to the modified permanent bilateral occlusion of the common carotid arteries (2VO) method, with right common carotid artery being first occluded, and tested 3 months after the ischemic event. The effects of three different exercise protocols were examined: pre-ischemia, post-ischemia and pre+post-ischemia. Physical exercise consisted of sessions of 20-min, 3 times per week during 12 weeks (moderate intensity). Rats were submitted to cognitive assessment, in both reference and working spatial memory and after the last testing session were sacrificed to have oxidative stress parameters determined. Hypoperfusion caused a significant cognitive deficit in both spatial water maze tasks and this effect was reversed in rats receiving exercise protocol post and pre+post the ischemic event. Moreover, forced regular treadmill exercise regulated oxidative damage and antioxidant enzyme activity in the hippocampus. These results suggest that physical exercise protects against cognitive and biochemical impairments caused by chronic cerebral hypoperfusion.     

Treinta y cinco años del pensamiento divergente: teoría de la creatividad de Guilford

Resumen

Se analiza cómo ha evolucionado el concepto de pensamiento divergente en la teoría de Guilford. Las primeras definiciones en el año 50 dentro del marco del «Proyecto de Investigación de Aptitudes» postulan una serie de rasgos distintivos para el pensamiento divergente que luego serían objeto de confirmación o refutación a partir de los estudios factoriales.

Dentro del modelo de la «Estructura del Intelecto» de Guilford, se ha ido delimitando la importancia de tales rasgos modificando la definición inicial de algunos, como la sensibilidad a los problemas que, aunque fue concebida como un factor de evaluación, finalmente su definición factorial es de una aptitud de conocimiento; rechazando la importancia de otros para la creatividad, como los factores de análisis y síntesis o, finalmente potenciando otros que inicialmente tuvieron menor consideración, como las aptitudes para las transformaciones que, son consideradas por Guilford como una contribución tan importante para la creatividad como la producción divergente.     

Quest for optimum human population per nation

The world is being saturated with population to a point where its life‐support systems may be in danger of losing their ability to maintain environmental stability. Thus, there is an urgent need for scientists and decision makers to develop working models in which information about the population, resource exhaustion, and pollution of each nation is contained. The criteria for determining optimum human population are reviewed, and a bionomic model that incorporates the complex web of economic and political systems within an ecological framework is presented to solve the problem of how large a population each nation should have.
