This study explored infant feeding practice meanings of HIV-positive mothers. Informants were eight black South African mothers (age range 18–29 years) enrolled in a mother-to-child transmission (MTCT) prevention programme. In-depth interviews on factors that influence exclusive breast-feeding were conducted with the mothers. Thematic analysis of the data yielded meanings around practices of knowledge contestation with health care providers and family, work demands, and personal preferences. Moreover, successful breast-feeding by mothers with HIV status may depend on addressing contradictory messages by health workers on infant feeding and community and family pressure to mix-feed the infant children.  相似文献

Bioethicists often draw sharp distinctions between hope and states like denial, self-deception, and unrealistic optimism. But what, exactly, is the difference between hope and its more suspect cousins? One common way of drawing the distinction focuses on accuracy of belief about the desired outcome: Hope, though perhaps sometimes misplaced, does not involve inaccuracy in the way that these other states do. Because inaccurate beliefs are thought to compromise informed decision making, bioethicists have considered these states to be ones where intervention is needed either to correct the person’s mental state or to persuade the person to behave differently, or even to deny the person certain options (e.g., another round of chemotherapy). In this article, we argue that it is difficult to determine whether a patient is really in denial, self-deceived, or unrealistically optimistic. Moreover, even when we are confident that beliefs are unrealistic, they are not always as harmful as critics contend. As a result, we need to be more permissive in our approach to patients who we believe are unrealistically optimistic, in denial, or self-deceived—that is, unless patients significantly misunderstand their situation and thus make decisions that are clearly bad for them (especially in light of their own values and goals), we should not intervene by trying to change their mental states or persuade them to behave differently, or by paternalistically denying them certain options (e.g., a risky procedure).  相似文献

Crisis incidents are volatile situations that can pose significant risk to those involved and to law enforcement. The idiosyncratic conditions that lead to such incidents, as well as their volatility, often militate against consistent explanatory models. However, the application of overarching paradigms, such as the action systems model, has shown some promise in imposing order in the domain. Recent research has successfully differentiated crisis incidents into the four distinct modes of the action systems model: conservative, adaptive, integrative, and expressive. The purpose of this paper is to attempt to replicate this recent study using 242 cases from the United States, Ireland, Canada, and Sweden. Data analysis involves smallest space analyses and constrained multidimensional scaling. Although the results supported the underlying structure of original proposed behavioural model, there are a few deviances. These differences along with the potential influence of cultural variations, offence variable selection, the type of incident, and the sample under scrutiny are discussed. It is evident that there remain several challenges, and further research is required, prior to developing a unified framework.  相似文献

Frontostriatal networks play critical roles in grounding action semantics and syntactic skills. Indeed, their atrophy distinctively disrupts both domains, as observed in patients with Huntington's disease (HD) and Parkinson's disease, even during early disease stages. However, frontostriatal degeneration in these conditions may begin up to 15 years before the onset of clinical symptoms, opening avenues for pre‐clinical detection via sensitive tasks. Such a mission is particularly critical in HD, given that patients’ children have 50% chances of inheriting the disease. Against this background, we assessed whether deficits in the above‐mentioned domains emerge in subjects at risk to develop HD. We administered tasks tapping action semantics, object semantics, and two forms of syntactic processing to 18 patients with HD, 19 asymptomatic first‐degree relatives, and sociodemographically matched controls for each group. The patients evinced significant deficits in all tasks, but only those in the two target domains were independent of overall cognitive state. More crucially, relative to controls, the asymptomatic relatives were selectively impaired in action semantics and in the more complex syntactic task, with both patterns emerging irrespective of the subjects’ overall cognitive state. Our findings highlight the relevance of these dysfunctions as potential prodromal biomarkers of HD. Moreover, they offer theoretical insights into the differential contributions of frontostriatal hubs to both domains while paving the way for innovations in diagnostic procedures.  相似文献

HIV testing is important in terms of prevention and treatment. However, HIV testing rates in the Spanish general population remains low. Therefore, HIV testing promotion constitutes a key issue. A high level of knowledge about HIV/AIDS is associated with having been tested for HIV. The general aim of this study was to determine the prevalence of people who had ever been tested for HIV in Spain. The sample consisted of 1,106 participants from the general population — 60.0% females and 40.0% males — aged between 17 and 55 years old. The assessment instruments were a questionnaire on sociodemographic data and HIV testing, a scale of knowledge about STIs and HIV/AIDS, and a scale of concern about STIs/HIV. Results showed that greater knowledge about STIs and HIV was associated with a greater likelihood of being tested for HIV (OR = .77; 95.0% CI = .73–.82; p < .05). In addition, higher concern about HIV/AIDS decreased the likelihood of not having been tested for HIV (OR = .87; 95.0% CI = .83–.92; p < .05). In fact, the higher participants concern about STIs was, the lower their likelihood of not having been tested for HIV was (OR = .87; 95.0% CI = .83–.91; p < .05). It is necessary to promote HIV testing in the general population as well as to consider their socio-demographic and psychological characteristics.  相似文献

The aim of this analysis was to explore whether pre-treatment intervention preferences were related to outcomes for patients with persistent sub-threshold and mild depression who received one of two treatment types. Thirty-six patients took part in a two-arm, parallel group, pilot randomized controlled trial that compared short term (3 month and 6 month) outcomes of person-centred counselling (PCC) compared with low-intensity, CBT-based guided self-help (LICBT). Patient preferences for the two interventions were assessed at baseline assessment, and analysed as two independent linear variables (pro-PCC, pro-LICBT). Eight out of 30 interactions between baseline treatment preferences and treatment type were found to be significant at the p < .05 level. All were in the predicted direction, with patients who showed a stronger preference for a treatment achieving better outcomes in that treatment compared with the alternative. However, pro-LICBT was a stronger predictor of outcomes than pro-PCC. The findings provide preliminary support that treatment preferences should be taken into account when providing interventions for patients with persistent sub-threshold and mild depression. It is recommended that further research analyses preferences for different treatment types as independent variables, and examines preferences for format of treatment (e.g. guided self-help vs. face-to-face).  相似文献

Four experiments examined people's responses to intergroup violence either committed or suffered by their own group. Experiment 1 demonstrated that Serbs who strongly glorified Serbia were more supportive of future violence against, and less willing to reconcile with, Bosniaks after reading about Serbian victimization by Bosniaks rather than Serbian transgressions against Bosniaks. Replicating these effects with Americans in the context of American–Iranian tensions, Experiment 2 further showed that demands for retributive justice explained why high glorifiers showed asymmetrical reactions to ingroup victimization vs. perpetration. Again in the Serb and the American context, respectively, Experiments 3 and 4 demonstrated that post‐conflict international criminal tribunals can help satisfy victim group members' desire for retributive justice, and thereby reduce their support for future violence and increase their willingness to reconcile with the perpetrator group. The role of retributive justice and the use of international criminal justice in intergroup conflict (reduction) are discussed.  相似文献
