Resilience and the burnout-engagement model in formal caregivers of the elderly

This paper investigates the relationship between resilience and positive/negative mental aspects of psychological well-being in formal caregivers for the elderly. The sample consisted of 265 caregivers who work in different residential homes in Extremadura and Castilla y León (Spain). The instruments used included the Connor-Davidson Resilience Scale , the Maslach Burnout Inventory-General Survey and the Utrecht Work Engagement Scale. The most significant findings show that caregivers with higher levels of resilience also have higher levels of professional efficacy and job engagement (vigor, dedication and absorption) and appear to be less emotionally exhausted or cynical than caregivers with lower levels of resilience. It cannot be concluded that more resilient caregivers will not get burned out, but they develop better engagement skills. As they strengthen these personal attributes, they become less vulnerable to burnout.     

Reading and Writing: Psychoanalytical Treatment in a Case of Paranoia

Difficulties encountered in clinical work with psychoses require psychoanalytical approaches different from those used for treating neurosis. The authors use a clinical case of a paranoiac patient to highlight the role played by writing, drawing, and painting in the psychoanalytical treatment of psychosis. They also discuss the role of the reader-analyst in this patient’s transferential process, which led to the emergence of a new subjectivity.     

The most efficient sequence of study depends on the type of test

Across three experiments featuring naturalistic concepts (psychology concepts) and naïve learners, we extend previous research showing an effect of the sequence of study on learning outcomes, by demonstrating that the sequence of examples during study changes the representation the learner creates of the study materials. We compared participants' performance in test tasks requiring different representations and evaluated which sequence yields better learning in which type of tests. We found that interleaved study, in which examples from different concepts are mixed, leads to the creation of relatively interrelated concepts that are represented by contrast to each other and based on discriminating properties. Conversely, blocked study, in which several examples of the same concept are presented together, leads to the creation of relatively isolated concepts that are represented in terms of their central and characteristic properties. These results argue for the integrated investigation of the benefits of different sequences of study as depending on the characteristics of the study and testing situation.     

Suggested visual hallucinations in and out of hypnosis

We administered suggestions to see a gray-scale pattern as colored and a colored pattern in shades of gray to 30 high suggestible and eight low suggestible students. The suggestions were administered twice, once following the induction of hypnosis and once without an induction. Besides rating the degree of color they saw in the stimuli differently, participants also rated their states of consciousness as normal, relaxed, hypnotized, or deeply hypnotized. Reports of being hypnotized were limited to highly suggestible participants and only after the hypnotic induction had been administered. Reports of altered color perception were also limited to high suggestibles, but were roughly comparable regardless of whether hypnosis had been induced. These data indicate that suggestible individuals do not slip into a hypnotic state when given imaginative suggestions without the induction of hypnosis, but nevertheless report experiencing difficult suggestions for profound perceptual alterations that are pheonomenologically similar to what they report in hypnosis.     

Medical practitioners' competence and confidentiality decisions with a minor: An anorexia nervosa case study

Minors (i.e., those under 18 years of age) hold a tenuous legal position in medical settings. While recent legal authority in numerous jurisdictions affords competent minors the right to consent to medical treatment, the guidelines for assessing competence are often vague or non-existent. In addition, these changes have not adequately addressed the issue of confidentiality, and it is unclear whether general practitioners (GPs) owe a duty of confidentiality to competent minors. As medical practitioners are the first point of contact in medical settings, the present study explored GPs' competence and confidentiality determinations regarding a 16-year-old female patient who presented with symptoms of an eating disorder. Questionnaires and hypothetical scenarios were sent to a sample of 1000 GPs, of which 305 responded. Results indicated that 62% of respondents would have found the patient competent, while 82% would have maintained her confidentiality. However, analysis of the rationales provided for these decisions revealed a wide discrepancy in GPs' understanding and implementation of current legal principles. This research highlights the necessity of providing GPs with clear guidelines regarding competence and confidentiality determinations when dealing with minors.     

A convex approach for multicriteria decision making in hierarchical systems

In this paper hierarchical multicriteria optimization problems are addressed in a convex programming framework. It is assumed that the criteria are aggregated into a nonlinear function, which renders the problem nonseparable, in general. The projection of the problem onto the criteria space is used to obtain an equivalent separable problem, solved through a relaxation procedure implemented on basis of a multilevel structure. At the upper level of the structure, the decision making process involves the solution of a multicriteria problem formulated in the criteria space. The solution encountered at the upper level originates a lower level parametric optimization problem with separable structure that can be treated by standard coordination-decomposition techniques. The convergence of the overall procedure is ensured. The paper includes an application of the approach proposed for the control of dynamic systems with linear quadratic structure. © 1998 John Wiley & Sons, Ltd.     

The Human Species Origin: Views of Biology Teachers from Three Latin American Countries

This paper intends to investigate whether the differences in country religiosity can influence biology teachers’ views about biological evolution, especially the human origin. Since Argentina, Brazil and Uruguay have differences in religiosity, teachers from these countries were asked to answer to the question of the European questionnaire BIOHEAD-CITIZEN: “The emergence of the human species (Homo sapiens) was just as improbable as the emergence of any other species.” From their answers, it was possible to estimate how biology teachers conceive the origin of the humankind, whether they perceive it as a natural phenomenon or a special event. The four Barbour’s categories concerning the relationship between science and religion (Conflict, Independence, Dialogue and Integration) were used to analyze the results in these three countries. Results showed that, in general, teachers of Uruguay (a secular country) and Argentina (a constitutional Catholic country) had a clearer position of separation between science and religion whereas the teachers of Brazil (with a relative secularism), tended to do not make a separation between science and religion. It could be concluded that the type of the teachers’ religion rather than the secularism of state is more influencial on building teachers’ views about human origin.     

Motor Cortex Plasticity in Children With Spastic Cerebral Palsy: A Systematic Review

A review of the literature was performed to answer the following questions: Does motor cortex excitability correlate with motor function? Do motor cortex excitability and cortex activation change after a rehabilitation program that results in improvements in motor outcomes? Can the 10–20 electroencephalography (EEG) system be used to locate the primary motor cortex when employing transcranial direct current stimulation? Is there a bihemispheric imbalance in individuals with cerebral palsy similar to what is observed in stroke survivors? the authors found there is an adaptation in the geometry of motor areas and the cortical representation of movement is variable following a brain lesion. The 10–20 EEG system may not be the best option for locating the primary motor cortex and positioning electrodes for noninvasive brain stimulation in children with cerebral palsy.
