Solvability of mental health care in the Family Health Strategy: social representation of professionals and users

Objective To aprehend the social representations about the solvability in mental health care with users of the Family Health Strategy and professionals of family health teams and of the Center for Psychosocial Care. Method A qualitative study using semi-structured interviews for data collection, and the Alceste software for analysis. This software uses the Hierarchical Descending Classification based on the examination of lexical roots, considering the words as units and providing context in the corpus. Results The representations emerge in two opposing poles: the users require satisfaction with care and the professionals realize the need for improvement of health actions. Although the matricial support in mental health and the home visits are developed, the barriers related to investment in health, continuing education and organization of care persist. Conclusion The different representations enable improvements in customer service, solvability of care and aggregate knowledge and practices in the expanded perspective of health needs in the family, social and therapeutic context.


Imaging pheromone sensing in a mouse vomeronasal acute tissue slice preparation.

Peter Karlson and Martin Lüscher used the term pheromone for the first time in 1959 to describe chemicals used for intra-species communication. Pheromones are volatile or non-volatile short-lived molecules secreted and/or contained in biological fluids, such as urine, a liquid known to be a main source of pheromones. Pheromonal communication is implicated in a variety of key animal modalities such as kin interactions, hierarchical organisations and sexual interactions and are consequently directly correlated with the survival of a given species. In mice, the ability to detect pheromones is principally mediated by the vomeronasal organ (VNO), a paired structure located at the base of the nasal cavity, and enclosed in a cartilaginous capsule. Each VNO has a tubular shape with a lumen allowing the contact with the external chemical world. The sensory neuroepithelium is principally composed of vomeronasal bipolar sensory neurons (VSNs). Each VSN extends a single dendrite to the lumen ending in a large dendritic knob bearing up to 100 microvilli implicated in chemical detection. Numerous subpopulations of VSNs are present. They are differentiated by the chemoreceptor they express and thus possibly by the ligand(s) they recognize. Two main vomeronasal receptor families, V1Rs and V2Rs, are composed respectively by 240 and 120 members and are expressed in separate layers of the neuroepithelium. Olfactory receptors (ORs) and formyl peptide receptors (FPRs) are also expressed in VSNs. Whether or not these neuronal subpopulations use the same downstream signalling pathway for sensing pheromones is unknown. Despite a major role played by a calcium-permeable channel (TRPC2) present in the microvilli of mature neurons TRPC2 independent transduction channels have been suggested. Due to the high number of neuronal subpopulations and the peculiar morphology of the organ, pharmacological and physiological investigations of the signalling elements present in the VNO are complex. Here, we present an acute tissue slice preparation of the mouse VNO for performing calcium imaging investigations. This physiological approach allows observations, in the natural environment of a living tissue, of general or individual subpopulations of VSNs previously loaded with Fura-2AM, a calcium dye. This method is also convenient for studying any GFP-tagged pheromone receptor and is adaptable for the use of other fluorescent calcium probes. As an example, we use here a VG mouse line, in which the translation of the pheromone V1rb2 receptor is linked to the expression of GFP by a polycistronic strategy.

In the context of a daycare center: nursing and their representations of child care as an educational act

This study aimed to analyze the social representations in the professionals of technical staff, who work with children at USP daycare centers. Eight professionals of the nursing field underwent a semi-structured interview. The interviews were recorded and transcribed in their entirety and the content of the discourse was subjected to thematic-categorical analysis. The categories were transformed into variables and processed by the software Classification Hiérarchique Classificatoire et Cohésitive (CHIC®) and analyzed by the hierarchical similarity tree. The results indicate that actions to promote health are reported as educational and transformative, in which health care gains new meaning through contextualized conceptions in the field of child education. We conclude that professionals attribute new meanings to their practices in the health care environment of daycare centers as their representations shifts from the logic of the biomedical field to a logic of educational care. In this sense, they perceive themselves as being challenged to establish an interaction with the children in terms of their activities related to the promotion of health and in an educational act.

Primary Care Sensitive Hospitalization: users detect flaws on the access to services

The aim of this study is to analyze and understand the reasons for the occurrence of sensitive hospitalizations in accordance with users. Qualitative study conducted with users who were admitted to Pedreira General Hospital, in São Paulo. The data was collected through semi structured interviews and thereafter, transcribed and processed in the electronic program Alceste. When analyzing the content, the access was seized fundamentally as an empirical category, bringing up problems that later deserved, from the Brazilian Ministry of Health, a specific Program to improve the quality and access to primary care. The hierarchical and pyramidal organization shape from the health system in the city of São Paulo can be one of the important aspects for the access matter and established as an important restricting factor in the primary care role in reducing or even preventing the occurrence of these hospitalizations.

Análise da performance organizacional: Proposta de um modelo do balanced scorecard para a avaliação do desempenho do comando da 1ª região militar

Esta pesquisa gira à volta da avaliação do desempenho organizacional com enfoque no sistema denominado Balanced Scorecard. Esta ferramenta, criada no início da década de noventa, por David Norton e Robert Kaplan, tem vindo a contagiar os gestores, e nos dias de hoje várias são as organizações que beneficiam dela para obter excelência. A primeira metodologia foi apresentada em mil novecentos e noventa e três (1993), constituída por oito etapas. No ano de mil novecentos e noventa e seis (1996), os autores desenvolveram uma nova metodologia, melhorada, composta por dez etapas. Começámos por fazer um levantamento teórico dos conceitos ligados a esta ferramenta, as suas vantagens e desvantagens, as fases da sua execução, os possíveis obstáculos ao seu sucesso e os frutos que poderão ser colhidos com a sua implementação. Através de uma proposta de implementação, escolhemos o Comando da 1ª Região Militar, para verificar quais serão os impactos na gestão desta organização. Do diagnóstico situacional efectuado com base em entrevistas, análise documental e observação, verificámos que a organização possui algumas insuficiências ao nível do desempenho de gestão, derivadas sobretudo da situação logística e financeira. Na construção do mapa estratégico, principal componente do Balanced scorecard, vimo-nos na necessidade de deslocar a perspectiva do cliente ou de mercado para o topo de configuração, devido à natureza do objecto negocial da organização em estudo. O modelo de avaliação de desempenho desenvolvido evidenciou a importância que a utilização deste sistema poderá ter na melhoria das actividades castrenses, sobretudo pelo aumento do nível de comunicação entre os subgrupos e a gestão de topo, neste caso, o Pessoal de Comando e as Pequenas Unidades, devido à natureza e qualidade das informações fornecidas pelo mapa estratégico. The aim of this study is to look at the organizational performance measurement system, with a special emphasis upon the so called Balanced Scorecard System. This tool, created at the beginning of the 1990’s by David Norton and Robert Kaplan, has been gaining the enthusiasm of administrator, and at the present time, several organizations are using it in the search for excellence. The first methodology was presented in 1993 and was formed by eight steps. In 1996, however, its creators developed an improved version of this methodology, now composed by ten steps. We start by doing a research of the theoretical concepts related to this tool, its advantages and disadvantages, the stages of its implementation, possible obstacles to its success, and the benefits that can come from its use. Based on an implementation proposal, we chose the First Military Command Region of Cape Verde to study the possible impacts of this system on the management of that Institution. From an investigation on the existent situation, based on interviews, analysis of documents and “in locus” observation, we realised that the institution shows some administrative insufficiencies, mainly due to its logistics and financial situation. In the building of the strategic map, the main component of the Balanced Scorecard System, we were obliged to move the perspective of the client or the market to the top of the configuration, because of the nature of the trading object of the institution being studied. The performance measurement model developed, clearly showed the importance that the implementation of this system might have on the improvement of the Military activities, mainly because of the improvement on the type of communication that can be established between the subgroups and the higher hierarchical levels, in this case, the Commander Staff and the lower Units, due to the type and quality of the information provided by the strategic map.

How geographic distance and depth drive ecological variability and isolation of demersal fish communities in an archipelago system (Cape Verde, Eastern Atlantic Ocean)

Cape Verde is a tropical oceanic ecosystem, highly fragmented and dispersed, with islands physically isolated by distance and depth. To understand how isolation affects the ecological variability in this archipelago, we conducted a research project on the community structure of the 18 commercially most important demersal fishes. An index of ecological distance based on species relative dominance (Di) is developed from Catch Per Unit Effort, derived from an extensive database of artisanal fisheries. Two ecological measures of distance between islands are calculated: at the species level, DDi, and at the community level, DD (sum of DDi). A physical isolation factor (Idb) combining distance (d) and bathymetry (b) is proposed. Covariance analysis shows that isolation factor is positively correlated with both DDi and DD, suggesting that Idb can be considered as an ecological isolation factor. The effect of Idb varies with season and species. This effect is stronger in summer (May to November), than in winter (December to April), which appears to be more unstable. Species react differently to Idb, independently of season. A principal component analysis on the monthly (DDi) for the 12 islands and the 18 species, complemented by an agglomerative hierarchical clustering, shows a geographic pattern of island organization, according to Idb. Results indicate that the ecological structure of demersal fish communities of Cape Verde archipelago, both in time and space, can be explained by a geographic isolation factor. The analytical approach used here is promising and could be tested in other archipelago systems.

The Effect of Four-Lane to Three-Lane Conversion on the Number of Crashes and Crash Rates in Iowa Roads, June 2005

We analyze crash data collected by the Iowa Department of Transportation using Bayesian methods. The data set includes monthly crash numbers, estimated monthly traffic volumes, site length and other information collected at 30 paired sites in Iowa over more than 20 years during which an intervention experiment was set up. The intervention consisted in transforming 15 undivided road segments from four-lane to three lanes, while an additional 15 segments, thought to be comparable in terms of traffic safety-related characteristics were not converted. The main objective of this work is to find out whether the intervention reduces the number of crashes and the crash rates at the treated sites. We fitted a hierarchical Poisson regression model with a change-point to the number of monthly crashes per mile at each of the sites. Explanatory variables in the model included estimated monthly traffic volume, time, an indicator for intervention reflecting whether the site was a “treatment” or a “control” site, and various interactions. We accounted for seasonal effects in the number of crashes at a site by including smooth trigonometric functions with three different periods to reflect the four seasons of the year. A change-point at the month and year in which the intervention was completed for treated sites was also included. The number of crashes at a site can be thought to follow a Poisson distribution. To estimate the association between crashes and the explanatory variables, we used a log link function and added a random effect to account for overdispersion and for autocorrelation among observations obtained at the same site. We used proper but non-informative priors for all parameters in the model, and carried out all calculations using Markov chain Monte Carlo methods implemented in WinBUGS. We evaluated the effect of the four to three-lane conversion by comparing the expected number of crashes per year per mile during the years preceding the conversion and following the conversion for treatment and control sites. We estimated this difference using the observed traffic volumes at each site and also on a per 100,000,000 vehicles. We also conducted a prospective analysis to forecast the expected number of crashes per mile at each site in the study one year, three years and five years following the four to three-lane conversion. Posterior predictive distributions of the number of crashes, the crash rate and the percent reduction in crashes per mile were obtained for each site for the months of January and June one, three and five years after completion of the intervention. The model appears to fit the data well. We found that in most sites, the intervention was effective and reduced the number of crashes. Overall, and for the observed traffic volumes, the reduction in the expected number of crashes per year and mile at converted sites was 32.3% (31.4% to 33.5% with 95% probability) while at the control sites, the reduction was estimated to be 7.1% (5.7% to 8.2% with 95% probability). When the reduction in the expected number of crashes per year, mile and 100,000,000 AADT was computed, the estimates were 44.3% (43.9% to 44.6%) and 25.5% (24.6% to 26.0%) for converted and control sites, respectively. In both cases, the difference in the percent reduction in the expected number of crashes during the years following the conversion was significantly larger at converted sites than at control sites, even though the number of crashes appears to decline over time at all sites. Results indicate that the reduction in the expected number of sites per mile has a steeper negative slope at converted than at control sites. Consistent with this, the forecasted reduction in the number of crashes per year and mile during the years after completion of the conversion at converted sites is more pronounced than at control sites. Seasonal effects on the number of crashes have been well-documented. In this dataset, we found that, as expected, the expected number of monthly crashes per mile tends to be higher during winter months than during the rest of the year. Perhaps more interestingly, we found that there is an interaction between the four to three-lane conversion and season; the reduction in the number of crashes appears to be more pronounced during months, when the weather is nice than during other times of the year, even though a reduction was estimated for the entire year. Thus, it appears that the four to three-lane conversion, while effective year-round, is particularly effective in reducing the expected number of crashes in nice weather.

L'expérience de la ménopause : étude ethnographique en Suisse Romande et au Centre-Cameroun

Aujourd'hui, la construction sociale de la ménopause intéresse de nombreux chercheurs en sciences sociales. Cependant, la façon dont les femmes vivent ou se représentent cet événement reste peu documentée. L'objectif de cette thèse est donc d'approfondir la compréhension de l'expérience de la ménopause en accordant une place primordiale aux discours et aux pratiques des femmes elles-mêmes. En s'appuyant sur une recherche ethnographique en Suisse romande et au Centre-Cameroun, cette étude parcourt différentes dimensions de l'expérience de la ménopause (représentations, vécus, pratiques de gestion) qui, corrélées les unes aux autres, forment un tout. Au-delà des divergences que l'on peut observer au niveau culturel, de la situation économique et sociale des femmes, des systèmes de santé et du statut occupé par la ménopause dans les deux pays, les résultats de ce travail montrent que les expériences de la ménopause chez les Suissesses et les Camerounaises interviewées ne peuvent pas simplement être classifiées de manière binaire ou dichotomique. Dans chacun des contextes, ces expériences sont plurielles et dépendent de plusieurs facteurs. D'une part, elles découlent d'une observation empirique de la part de ces femmes elles-mêmes et de leurs interactions avec différents acteurs dont les médias (particulièrement en Suisse), les pairs, les proches et les professionnels de la santé. D'autre part, elles sont influencées par de nombreuses variables parmi lesquelles le contexte économique, socioculturel, familial et conjugal, le statut professionnel, la prévalence des troubles ressentis et le statut ménopausique de ces femmes. Mais, ces facteurs ne sont pas hiérarchisés puisqu'ils agissent différemment pour chacune d'entre elles. Dès lors, s'il apparaît que les expériences ménopausiques n'échappent point aux déterminations sociales, il n'en demeure pas moins qu'elles relèvent aussi des capacités réflexives des femmes, les conduites sociales n'étant pas réductibles à des applications des codes intériorisés. Au fil du travail, la médicalisation de la ménopause, bien qu'existant à des degrés variables entre la Suisse et le Cameroun, a émergé comme une problématique transversale. Interrogeant les logiques qui la sous-tendent, cette étude se propose d'analyser le rôle que jouent les femmes elles-mêmes dans ce processus. - Today, the social construction of the menopause is of great interest for many researchers in social sciences. Neverthless, the way of living or of representing this event is still little documented. The aim of this thesis is to study thoroughly the understanding of menopausal experience through the discourses and practices of women themselves. Based on an ethnograph ic research, in French-speaking Switzerland and in Centre-Cameroon, this study looks at different dimensions of menopausal experience (representations, real-life experiences, pratices) that, connected to each other, form a whole. Inspite of the cultural, economic, social, health systems and menopausal status differences between these two countries, the results of this thesis show that menopausal experiences among the Swiss and the Cameroonians interviewee can not simply be classified in two dichotomous groups. In each context, those experiences are plural and depend on several factors. On the one hand, they arise from women's own empirical observations and from their interactions with several actors like the media (especially in Switzerland), the peers, the people closest to them and health professionals. On the other hand, they are influenced by many elements such as the economical, sociocultural, family and marital context, the professional status, the prevalence of felt disorders and the menopausal status of those women. But, these factors are not hierarchical beacause they operate differently for each person. Accordingly, if menopausal experiences don't escape from social determinism, nonetheless they also depend on the reflexive capacities of women beacause social conducts can not be reduced to the application of interiorised codes. Through this work, the médicalisation of the menopause, even though varying between Switzerland and Cameroon, comes to light as a cross-cutting problematic. Questioning its underlying logic, this study proposes to analyse the role that women themselves play in this process.

Campaign effects in direct-democratic votes in Switzerland

The purpose of this article is to analyse the conditions under which referendum campaigns have an impact on voting choices. Based on a model of opinion formation that integrates both campaign effects and partisan effects, we argue that campaign effects vary according to the context of the popular vote (size and type of conflict among the party elite and intensity and direction of the referendum campaign). We test our hypotheses with two-step estimations for hierarchical models on data covering 25 popular votes on foreign, European and immigration policy in Switzerland. Our results show strong campaign effects and they suggest that their strength and nature are indeed highly conditional on the context of the vote: the type of party coalition pre-structures the patterns of individual voting choices, campaign effects are higher when the campaign is highly intense and they are more symmetric when it is balanced.

Emotion and reason in everyday risk perception

Although research has documented the importance of emotion in risk perception, little is knownabout its prevalence in everyday life. Using the Experience Sampling Method, 94 part-timestudents were prompted at random via cellular telephones to report on mood state and threeemotions and to assess risk on thirty occasions during their working hours. The emotions valence, arousal, and dominance were measured using self-assessment manikins (Bradley &Lang, 1994). Hierarchical linear models (HLM) revealed that mood state and emotions explainedsignificant variance in risk perception. In addition, valence and arousal accounted for varianceover and above reason (measured by severity and possibility of risks). Six risks were reassessedin a post-experimental session and found to be lower than their real-time counterparts.The study demonstrates the feasibility and value of collecting representative samples of data withsimple technology. Evidence for the statistical consistency of the HLM estimates is provided inan Appendix.

Aplicação de SIG no Processamento do Inventário Florestal Nacional – Cabo Verde

Cabo Verde desde do século passado tem envidado esforço na florestação, sobretudo depois de 1975 para atenuar os efeitos da seca e da desertificação criando deste modo grandes áreas arborizadas. Entretanto, à medida que os recursos florestais foram sendo criados, a problemática da sua avaliação e da sua gestão sustentável, passaram a merecer maior atenção das autoridades nacionais. A lei florestal, promulgada em 1998 define como uma das atribuições e acções do Estado, através dos serviços florestais, a elaboração dos planos de gestão das zonas florestais. Este plano de gestão implica a análise e a apreciação de dados concretos e actualizados sobre a situação real das zonas florestais, sendo possível apenas através do inventário florestal nacional (IFN). Neste trabalho é proposta uma metodologia de processamento do IFN em que se utilizam as potencialidades dos Sistemas de Informação Geográfica (SIG). Foram utilizados para este trabalho os programas: ArcGis 9.1, para produção cartográfica, geoprocessamento e análise espacial e o Field-Map 8.1 para a classificação de ortofotos num esquema de classificação hierárquica, em cinco níveis, adaptado a Cabo Verde (classes de uso do solo adoptado ao esquema de classificação do território europeu – CORINE Land Cover e da Organização das Nações Unidas para a Agricultura e Alimentação (FAO). Os dados utilizados foram compilados no âmbito do projecto do inventário florestal. Os resultados obtidos, para a Ilha de Santiago, constituem uma base cartográfica para o IFN com diversos temas cartográficos, nomeadamente, mapas das zonas florestadas, mapas de ocupação do solo e mapas de amostras inventariáveis cuja metodologia de elaboração poderá ser facilmente replicada para as restantes ilhas do arquipélago.

A simple permutation test for clusteredness

Hierarchical clustering is a popular method for finding structure in multivariate data,resulting in a binary tree constructed on the particular objects of the study, usually samplingunits. The user faces the decision where to cut the binary tree in order to determine the numberof clusters to interpret and there are various ad hoc rules for arriving at a decision. A simplepermutation test is presented that diagnoses whether non-random levels of clustering are presentin the set of objects and, if so, indicates the specific level at which the tree can be cut. The test isvalidated against random matrices to verify the type I error probability and a power study isperformed on data sets with known clusteredness to study the type II error.

Appropriateness of respiratory care: evidence-based guidelines.

PRINCIPLES: Respiratory care is universally recognised as useful, but its indications and practice vary markedly. In order to improve the appropriateness of respiratory care in our hospital, we developed evidence-based local guidelines in a collaborative effort involving physiotherapists, physicians and health service researchers. METHODS: Recommendations were developed using the standardised RAND appropriateness method. A literature search was conducted based on terms associated with guidelines and with respiratory care. A working group prepared proposals for recommendations which were then independently rated by a multidisciplinary expert panel. All recommendations were then discussed in common and indications for procedures were rated confidentially a second time by the experts. The recommendations were then formulated on the basis of the level of evidence in the literature and on the consensus among these experts. RESULTS: Recommendations were formulated for the following procedures: non-invasive ventilation, continuous positive airway pressure, intermittent positive pressure breathing, intrapulmonary percussive ventilation, mechanical insufflation-exsufflation, incentive spirometry, positive expiratory pressure, nasotracheal suctioning and non-instrumental airway clearance techniques. Each recommendation referred to a particular medical condition and was assigned to a hierarchical category based on the quality of the evidence from the literature supporting the recommendation and on the consensus among the experts. CONCLUSION: Despite a marked heterogeneity of scientific evidence, the method used allowed us to develop commonly agreed local guidelines for respiratory care. In addition, this work fostered a closer relationship between physiotherapists and physicians in our institution.

Testing demographic models of effective population size.

Due to practical difficulties in obtaining direct genetic estimates of effective sizes, conservation biologists have to rely on so-called 'demographic models' which combine life-history and mating-system parameters with F-statistics in order to produce indirect estimates of effective sizes. However, for the same practical reasons that prevent direct genetic estimates, the accuracy of demographic models is difficult to evaluate. Here we use individual-based, genetically explicit computer simulations in order to investigate the accuracy of two such demographic models aimed at investigating the hierarchical structure of populations. We show that, by and large, these models provide good estimates under a wide range of mating systems and dispersal patterns. However, one of the models should be avoided whenever the focal species' breeding system approaches monogamy with no sex bias in dispersal or when a substructure within social groups is suspected because effective sizes may then be strongly overestimated. The timing during the life cycle at which F-statistics are evaluated is also of crucial importance and attention should be paid to it when designing field sampling since different demographic models assume different timings. Our study shows that individual-based, genetically explicit models provide a promising way of evaluating the accuracy of demographic models of effective size and delineate their field of applicability.
