Post-Mortem diagnosis of dementia by informant interview.

The diagnosis of normal cognition or dementia in the Brazilian Brain Bank of the Aging Brain Study Group (BBBABSG) has relied on postmortem interview with an informant. Objectives:To ascertain the sensitivity and specificity of postmortem diagnosis based on informant interview compared against the diagnosis established at a memory clinic. Methods:A prospective study was conducted at the BBBABSG and at the Reference Center for Cognitive Disorders (RCCD), a specialized memory clinic of the Hospital das Clínicas, University of São Paulo Medical School. Control subjects and cognitively impaired subjects were referred from the Hospital das Clínicas to the RCCD where subjects and their informants were assessed. The same informant was then interviewed at the BBBABSG. Specialists' panel consensus, in each group, determined the final diagnosis of the case, blind to other center's diagnosis. Data was compared for frequency of diagnostic equivalence. For this study, the diagnosis established at the RCCD was accepted as the gold standard. Sensitivity and specificity were computed. Results:Ninety individuals were included, 45 with dementia and 45 without dementia (26 cognitively normal and 19 cognitively impaired but non-demented). The informant interview at the BBBABSG had a sensitivity of 86.6% and specificity of 84.4% for the diagnosis of dementia, and a sensitivity of 65.3% and specificity of 93.7% for the diagnosis of normal cognition. Conclusions:The informant interview used at the BBBABSG has a high specificity and sensitivity for the diagnosis of dementia as well as a high specificity for the diagnosis of normal cognition

How reliable are group informant ratings?

The reliability of food security rating, a variant of the more familiar wealth ranking procedure, was tested in a rural area of Western Honduras. Twenty workshop sessions were conducted in 13 different communities, with members of organized small farmers' groups attended by a large agricultural development project. Participants were all poor farmers with no more than 10 hectares of land. Participants, who generally knew each other well, were split into small sets and each set was asked to rate the food security status of all households in their organized group. Inter-rater agreement was assessed using the Kappa statistic, and related to other characteristics of the informants and workshop sessions, using multiple regression methods. Agreement was very poor (median value 6 = 0.29), especially for the category "Intermittenly Food Insecure," and was associated with time elapsed since training of the session moderators. Women were 49 percent more likely than men to classify a given family as food insecure (P 0.001). The authors put forward seven different hypotheses to explain the poor reliability of the rating method, which should be investigated in future research if the credibility of the method is to be reinforced.Statistics. ,Food security Household. ,Small farmers. ,

Adequate screening of youngsters for depressive characteristics

Introduction. In order to set up an effective early-detection of depressive symptoms in youngsters, the current study aims to investigate whether two measure moments of the Children's Depression Inventory (CDI) improve screening and whether a multi-informant procedure is superior compared to a single-informant procedure thereby controlling for comorbid. symptoms. Method. Youngsters (10-15 years) filled in the CDI and an Anxiety Scale at Time 1 and the CDI and Youth Self Report one week later. Next, a structured clinical interview was administered. The Child Behaviour CheckList was filled in by the parents. Results. Two measure moments of the CDI are not more accurate in capturing disordered mood changes. Furthermore, parent reports were no significant contributor to the variance over and above the CDI. Discussion. A second moment does not increase screening accuracy. Further research on setting up an effective multistage screening procedure for depressive symptoms for youngsters is however necessary

Pixelated flesh

The pixel and the technique of pixelating faces belong to a politics of fear and a digital aesthetics of truth which shapes public perceptions of criminality and the threat of otherness. This article will draw on Paul Virilio's account of the pixel in Lost Dimension in order to analyze its specific role and operation in relation to contemporary representations of incarceration. In particular, the article will consider the figure of the incarcerated informant. The incarcerated criminal or informant plays a complex role as both subversive other and purveyor of truth and as such constitutes an important example of the ways in which pixelation functions as a visible signifier of a dangerous truth whilst blurring, erasing and, ultimately, dehumanizing those "speaking" this truth. Our discussion forms part of a larger analysis of the production, framing and circulation of images of otherness, identifying Virilio as key to debates around the violence of the screen

Local perspectives on humanitarian aid in Sri Lanka after the tsunami

Objectives: This case study examines the impact of humanitarian aid from the perspectives of local stakeholders in Sri Lanka following the tsunami disaster of December 2004. Study Design: Qualitative study using key-informant and focus group interviews. Methods: Key-informant and focus group interviews were conducted with tsunami survivors, community leaders, the local authorities and aid workers sampled purposively. Data collected was analysed using thematic analysis. Results: The study found that aid had aggravated social tensions and the lack of community engagement led to grievances. There was a perceived lack of transparency, beneficiary expectations were not always met and it was difficult to match aid to needs. Rapid participatory approaches to obtain beneficiary feedback in post disaster settings are possible but have limitations due to respondent bias. Conclusions: In order to mitigate adverse social impacts of their programmes, humanitarian aid agencies need to better understand the context in which aid is delivered. Beneficiary feedback is essential in disaster planning and response so that disaster response can be better matched to the needs of beneficiaries

Assertion, action, and context

A common objection to both contextualism and relativism about knowledge ascriptions is that they threaten knowledge norms of assertion and action. Consequently, if there is good reason to accept knowledge norms of assertion or action, there is good reason to reject both contextualism and relativism. In this paper we argue that neither contextualism nor relativism threaten knowledge norms of assertion or action
