Predictors of quality of life enjoyment and satisfaction in individuals living with HIV and AIDS in a resource-constrained setting in South Africa

The burden of HIV disease is concentrated in sub-Saharan Africa, particularly in South Africa (SA). Whilst there have been many studies conducted on the biomedical and socio-psychological aspects of HIV and AIDS, insufficient attention has been paid to the quality of life of those infected with the virus. The primary purpose of the study was to determine the predictors of quality of life enjoyment and satisfaction (Q-LES) among individuals infected with HIV. A battery of questionnaires, which included the Hospital Anxiety and Depression Scale (HADS) and the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), were administered to 121 participants. Data was analysed using SPSS. Of the total sample (n = 121), 74% were females. The study found that a large proportion (49.5%) of the sample within the age group 25–49 years old experienced psychological distress. Those who were not on antiretroviral treatment (ART) were significantly affected (66%). Psychological distress was significantly prevalent among HIV positive individuals and also the strongest predictor of Q-LES among these individuals.     

Quantification abilities in angelfish (Pterophyllum scalare): the influence of continuous variables

Previous studies investigating quantity discrimination have shown that angelfish are able to select the larger of two groups of conspecifics (shoals). The discrimination limits shown by angelfish were similar to those found for other vertebrates when large (≥4) and small quantities (<4) were presented. However, in these studies, no attempt was made to control for non-numerical features of the stimulus shoals and thus the question whether numerical or some quantitative attributes of the shoals were utilized for making the choices could not be answered. Here, we investigate whether angelfish can discriminate between shoals differing in numerical size using non-numerical attributes. We systematically manipulate density, inter-fish distance, and overall space occupied by the shoals, one factor at a time, and analyse the choices angelfish made between the contrasting stimulus shoals. The stimulus shoals consisted of contrasts between large (10 vs. 5) and small (3 vs. 2) number of conspecifics. We found density to be a sufficient condition for discrimination between large shoals as the test subjects preferred the more dense shoal. Manipulation of inter-fish distance indicated that this variable is not a necessary factor in discrimination at either shoal size contrast. Likewise, we found that the size of space occupied by the contrasted shoals also did not significantly influence discrimination. Sensitivity to the density of large shoals indicates that angelfish can discriminate shoal size using this non-numerical cue. Nevertheless, the factors we examined may represent only a subset of all possible non-numerical features upon which angelfish may base their discrimination. Thus, we suggest that further research is required to clarify whether and under what circumstances angelfish may use numerical or non-numerical features when discriminating between shoals of differing size.     

The Catholic Church,moral doctrine,and HIV prevention in Recife,Brazil: Negotiating the contradictions between religious belief and the realities of everyday life

Religious beliefs have had a key role in shaping local responses to HIV and AIDS. As the world's largest Catholic country, Brazil is no exception. Yet little research has been conducted to document how religious doctrine is enacted in practice among its lay leaders and followers. In this article, we present ethnographic research from Recife, Brazil, conducted to understand the way in which religious doctrines are interpreted at a local level. Contextualised within the sociology of contemporary Brazilian Catholicism, we draw on interviews with clergy members, lay leaders, and parishioners to discuss how the Catholic Church's vision of sexuality translates into everyday lives of its followers. We explore the disjuncture between the Catholic ideals of fidelity and delaying sex until marriage with the everyday reality of the Church's followers, highlighting the role that gender plays in defining sexual roles and expectations. We conclude by posing questions for future research and HIV prevention strategies considering the formal institutional response of the Brazilian Catholic Church to AIDS on the one hand, and the social and cultural contexts in which Catholics live their daily lives on the other.     

Multicriteria Classification with Unknown Categories: A Clustering–Sorting Approach and an Application to Conflict Management

This work proposes an approach to cluster and sort a set of alternatives considering multi‐criteria categories with a partial order structure. It can be considered a heuristic approach because it does not attempt to derive an optimal partial order among all conceivable clusters of alternatives. Rather than this, it intends to be a simple approach that is transparent to the Decision Maker (DM) whose assistance is sought to help shaping the results. The approach proposed arises from the conjugation of traditional Clustering analysis and Multi‐criteria sorting tools. At the outset, the number of categories and their characteristics is unknown. First, we need to detect only the clusters themselves on the basis of a similarity measure independent of the preferences of the DM. Next, we detect potential partial order relations that might exist between them, according to the subjective preferences of the DM. Such preferences are elicited only after the DM has examined the clusters detected and deemed that these categories made sense. The new approach performs very well in a real‐world problem of management of intragroup conflicts and conflict handling strategies. Copyright © 2012 John Wiley & Sons, Ltd.     

The cortisol awakening response in caregivers of schizophrenic offspring shows sensitivity to patient status

Abstract

Taking care of offspring during a prolonged period of time is probably one of the most stressful life experiences for parents. The present study compares the cortisol awakening response (CAR) in 38 long-term caregivers (mothers and fathers of schizophrenic relatives) with a control group of 32 non-caregivers. Factors such as general stress, caregiver burden, patient severity, and institutionalization were studied. Although a blunted CAR was observed in caregivers in comparison with controls, this difference was not significant. Among caregivers, the absence of institutionalization for the patient is associated with a lack of CAR in caregivers in comparison with caregivers of institutionally supported patients. General stress, caregiver burden, and patient severity themselves did not favor significant changes in CAR. CAR shows greater sensitivity to institutional support than patient severity and perceived stress. Further research is needed to explain the impact of these factors on health and the psychological factors involved.     

RECRIMINATION IN THE ANALYTIC SITUATION: A HYPOTHESIS ABOUT ITS INFLUENCE ON PSYCHOANALYTICAL GROUPS

This paper deals with certain distortions in communication generated by mutual recrimination that is the result of disturbances in the ideal agencies of both parties. Although the ideal ego, superego and ego ideal participate equally in reproach, it is the latter which is the most decisive. In clinical experience, recrimination may easily colour the analytic dialogue. In such cases, interpretation loses its sense of clarification and another type of dialogue replaces it. There, words are used to take possession of the other, for its autonomy is a threat to the static character of the pathology of mourning. The problem of recrimination has also tainted the development of psychoanalysis, to the point of disrupting the process of discovery itself. This paper deals with repercussions in the psychoanalytic movement and also in the elements that constitute its structure. Finally, different variations and disturbances in the psychoanalytic ideal are considered, as well as the involvement of the psychoanalytic institution in preserving or transforming the ideal. Here the importance of institutions and institutional ideals is emphasised. Finally, we suggest that ideals either encourage or hinder the working through of individual and collective mourning.     

Effects of chronic administration with high doses of testosterone propionate on behavioral and physiological parameters in mice with differing basal aggressiveness

The effects of testosterone propionate, an anabolic‐androgenic steroid, on the behavior displayed during a social encounter by gonadally intact male mice were investigated. Animals were distributed into three groups according to their attack latency in a pre‐screening test (high‐, moderate‐, and low‐ attacking mice) and each group received weekly injections of 60 or 120 mg/kg of testosterone or sesame oil for 10 weeks. Behavioral tests were then carried out. Afterwards, organs were weighed and blood samples collected in order to obtain hormonal data. Treatment had a differential impact on attack in the three groups of animals. Only the high‐attacking testosterone‐treated mice showed lower total duration of attack than their controls. Those that received 60 mg/kg spent more time exhibiting exploratory behaviors. As an index of the anabolic activity of the drug, all testosterone‐treated mice had heavier kidneys and, as an index of the androgenic activity of testosterone propionate, they had heavier seminal vesicles, lighter testes, and showed higher testosterone levels in a dose‐dependent way than their controls. Hence, the effect of treatment on peripheral physiological parameters was similar in all three groups whereas behavioral effects differed depending on basal aggressiveness, considered a characteristic of coping style.

Electric source localization adds evidence for task-specific CNVs

This study was an attempt to replicate recent magnetoencephalographic (MEG) findings on human task-specific CNV sources (Basile et al., Electroencephalography and Clinical Neurophysiology 90, 1994, 157-165) by means of a spatio-temporal electric source localization method (Scherg and von Cramon, Electroencephalography and Clinical Neurophysiology 62, 1985, 32-44; Scherg and von Cramon, Electroencephalography and Clinical Neurophysiology 65, 1986, 344-360; Scherg and Berg, Brain Electric Source Analysis Handbook, Version 2). The previous MEG results showed CNV sources in the prefrontal cortex of the two hemispheres for two tasks used, namely visual pattern recognition and visual spatial recognition tasks. In the right hemisphere, the sources were more anterior and inferior for the spatial recognition task than for the pattern recognition task. In the present study we obtained CNVs in five subjects during two tasks identical to the MEG study. The elicited electric potentials were modeled with four spatio-temporal dipoles for each task, three of which accounted for the visual evoked response and one that accounted for the CNV. For all subjects the dipole explaining the CNV was always localized in the frontal region of the head, however, the dipole obtained during the visual spatial recognition task was more anterior than the one obtained during the pattern recognition task. Thus, task-specific CNV sources were again observed, although the stable model consisted of only one dipole located close to the midline instead of one dipole in each hemisphere. This was a major difference in the CNV sources between the previous MEG and the present electric source analysis results. We discuss the possible basis for the difference between the two methods used to study slow brain activity that is believed to originate from extended cortical patches.
