Leitura, escrita e livro: determinantes de práticas culturais e desenvoltura social

In this article we aim to discuss the importance of reading, writing and the book in the subject’s performance in society. This discussion tries to put these elements in time and social space. Therefore we want to show how these cultural practices of reading and writing, combined with the book can determine the development of the subject, when able to access these technologies effectively. The expected results are the change of the superficial aspects and common sense about reading, books and writing. Hope that it contributes to the expansion of the discussions on these themes. We hope to collaborate to the discussion which is being developed within the educational context on reading, books and writing, and the relationship resulting from the development of the subject in society and their ability to read and write.

Diastolic blood pressure associated with accumulated work time among drivers and collectors

The relationship between diastolic blood pressure and the variables total cumulative working time and age was examined by regression analysis. The study was carried out among 839 bus drivers and conductors, users of an occupational health center in Campinas, S. Paulo State, Brazil. The main results were a positive association between diastolic blood pressure and cumulative working time, as well as an interaction between this variable and the bus worker's age.

A configuração de forças na constituição histórica do trabalho como estratégia de cuidado em saúde mental: problematizações foucaultianas

Investigated in this paper, as contributions to Foucault's genealogy of knowledge, the historical constitution of the joint activities between Work and Care in Mental Health (called Therapeutic Workshops, among other names) in their different purposes and dimensions that contributed to the production care of patients with psychological distress at different times. History is here understood as a multiplicity (and nonlinearity) of time series and various blending and shuffleforming speeches as truths. In conjunction we have discussed, we conclude that the work as a therapeutic modality in nursing homes, there emerged in the world of psychiatry, but of capitalism. Associated with measures of occupation "empty minds" of misfits, later earned the position of an instrument of discipline and social regulation. With the Psychiatric Reform, activities Work in Mental Health have been re-invented as spaces enablers of access to citizenship and contractuality social network users.

Essays on Bayesian Inference for Social Networks

This thesis presents Bayesian solutions to inference problems for three types of social network data structures: a single observation of a social network, repeated observations on the same social network, and repeated observations on a social network developing through time. A social network is conceived as being a structure consisting of actors and their social interaction with each other. A common conceptualisation of social networks is to let the actors be represented by nodes in a graph with edges between pairs of nodes that are relationally tied to each other according to some definition. Statistical analysis of social networks is to a large extent concerned with modelling of these relational ties, which lends itself to empirical evaluation. The first paper deals with a family of statistical models for social networks called exponential random graphs that takes various structural features of the network into account. In general, the likelihood functions of exponential random graphs are only known up to a constant of proportionality. A procedure for performing Bayesian inference using Markov chain Monte Carlo (MCMC) methods is presented. The algorithm consists of two basic steps, one in which an ordinary Metropolis-Hastings up-dating step is used, and another in which an importance sampling scheme is used to calculate the acceptance probability of the Metropolis-Hastings step. In paper number two a method for modelling reports given by actors (or other informants) on their social interaction with others is investigated in a Bayesian framework. The model contains two basic ingredients: the unknown network structure and functions that link this unknown network structure to the reports given by the actors. These functions take the form of probit link functions. An intrinsic problem is that the model is not identified, meaning that there are combinations of values on the unknown structure and the parameters in the probit link functions that are observationally equivalent. Instead of using restrictions for achieving identification, it is proposed that the different observationally equivalent combinations of parameters and unknown structure be investigated a posteriori. Estimation of parameters is carried out using Gibbs sampling with a switching devise that enables transitions between posterior modal regions. The main goal of the procedures is to provide tools for comparisons of different model specifications. Papers 3 and 4, propose Bayesian methods for longitudinal social networks. The premise of the models investigated is that overall change in social networks occurs as a consequence of sequences of incremental changes. Models for the evolution of social networks using continuos-time Markov chains are meant to capture these dynamics. Paper 3 presents an MCMC algorithm for exploring the posteriors of parameters for such Markov chains. More specifically, the unobserved evolution of the network in-between observations is explicitly modelled thereby avoiding the need to deal with explicit formulas for the transition probabilities. This enables likelihood based parameter inference in a wider class of network evolution models than has been available before. Paper 4 builds on the proposed inference procedure of Paper 3 and demonstrates how to perform model selection for a class of network evolution models.

Expression, regulation and clinical significance of soluble and membrane CD14 receptors in pediatric inflammatory lung diseases

BACKGROUND: Inflammatory lung diseases are a major morbidity factor in children. Therefore, novel strategies for early detection of inflammatory lung diseases are of high interest. Bacterial lipopolysaccharide (LPS) is recognized via Toll-like receptors and CD14. CD14 exists as a soluble (sCD14) and membrane-associated (mCD14) protein, present on the surface of leukocytes. Previous studies suggest sCD14 as potential marker for inflammatory diseases, but their potential role in pediatric lung diseases remained elusive. Therefore, we examined the expression, regulation and significance of sCD14 and mCD14 in pediatric lung diseases. METHODS: sCD14 levels were quantified in serum and bronchoalveolar lavage fluid (BALF) of children with infective (pneumonia, cystic fibrosis, CF) and non-infective (asthma) inflammatory lung diseases and healthy control subjects by ELISA. Membrane CD14 expression levels on monocytes in peripheral blood and on alveolar macrophages in BALF were quantified by flow cytometry. In vitro studies were performed to investigate which factors regulate sCD14 release and mCD14 expression. RESULTS: sCD14 serum levels were specifically increased in serum of children with pneumonia compared to CF, asthma and control subjects. In vitro, CpG induced the release of sCD14 levels in a protease-independent manner, whereas LPS-mediated mCD14 shedding was prevented by serine protease inhibition. CONCLUSIONS: This study demonstrates for the first time the expression, regulation and clinical significance of soluble and membrane CD14 receptors in pediatric inflammatory lung diseases and suggests sCD14 as potential marker for pneumonia in children.

Social control and smoking: Examining the moderating effects of different dimensions of relationship quality

A common form of social regulation of an individual’s health behavior is social control. The contextual model of social control assumes that higher relationship quality goes along with more beneficial effects of social control on health behavior. This study examined potential differential moderating effects of different dimensions of relationship quality on the associations between positive and negative social control and smoking behavior and hiding smoking. The sample consisted of 144 smokers (n = 72 women; mean age = 31.78, SD = 10.04) with a nonsmoking partner. Positive and negative social control, dimensions of relationship quality consensus, cohesion and satisfaction, numbers of cigarettes smoked (NCS), hiding smoking (HS), and control variables were assessed at baseline. Four weeks later NCS and HS were assessed again. Only for smokers with high consensus, but not cohesion and satisfaction, a negative association between positive control and NCS emerged. Moreover, smokers with high consensus tended to report more HS when being positively and negatively socially controlled. This also emerged for cohesion and positive control. Satisfaction with the relationship did not display any interaction effects. This study’s results emphasize the importance of differentiating not only between positive and negative social control but also between different dimensions of relationship quality in order to gain a comprehensive understanding of the dynamics in romantic dyads with regard to social regulation of behavioral change.

Demographic situation in operative medicine in Switzerland - time to react?

Objective: The decreasing proportion of physicians of Swiss origin and the increasing number of part-time jobs in operative medicine might lead to a shortage of physicians in operative disciplines in Switzerland. The objective of the present study was to analyze the current demographic situation in operative medicine in Switzerland. Methods: During the summer of 2011, a 19-item anonymous electronic questionnaire was mailed to all directors of departments in operative medicine in Switzerland. The questionnaire was designed to gather data about the characteristics of the participating departments, the demographics (including the appointment (consultant, attending or resident), the proportion of female and foreign physicians, the latter’s origin, and the number of part-time jobs with a working time between 20 and 90%), and the proportion of vacant posts. Results: Of 775 questionnaires mailed to all directors of departments in operative medicine in Switzerland, 183 (24%) were returned. Overall, 40% were female, and 42% foreign physicians. The proportion of part-time jobs amounted to 17%. Vacant posts were found in 2%. Conclusions: An expansion of study places at the medical universities and of the incentives for the incumbents in operative medicine is necessary to avert a shortage of physicians in Switzerland.

Tiempo libre y espacio público : Marcas de una civilización

El presente artículo procede de la investigación titulada "Tiempo libre, espacio público e identidad. Análisis del caso Parque Plaza Líber Seregni". El mismo pretende problematizar las nociones de tiempo libre y espacio público, y su papel en los procesos civilizatorios de Uruguay moderno, para pensar las configuraciones que adquieren tales conceptos en la actualidad. Para tal cometido, se realizarán aproximaciones teóricas desde la perspectiva de Milner, así como desde el abordaje histórico que propone Barrán. Uruguay, entre fines del siglo XIX y principios del XX, experimenta una serie de transformaciones políticas, económicas, sociales y culturales propiasde la "modernización". Un proyecto civilizador reorganizaría la vida social de la población, en relación a un territorio y una producción. La aprobación de la ley de las 8 horas, como señal de establecimiento de la frontera entre un tiempo de trabajo y un tiempo libre; así como la invención y fomento de los espacios públicos, dan lugar a las dicotomías tiempo de trabajo-tiempo libre y espacio público-espacio privado. Cabe preguntarse, ¿qué configuraciones adquieren estos binomios en la actualidad? ¿Bajo qué supuestos se asienta la popularización de estos términos?

Characterization of tomato Cycling Dof Factors reveals conserved and new functions in the control of flowering time and abiotic stress responses.

DNA binding with One Finger (DOF) transcription factors are involved in multiple aspects of plant growth and development but their precise roles in abiotic stress tolerance are largely unknown. Here we report a group of five tomato DOF genes, homologous to Arabidopsis Cycling DOF Factors (CDFs), that function as transcriptional regulators involved in responses to drought and salt stress and flowering-time control in a gene-specific manner. SlCDF1?5 are nuclear proteins that display specific binding with different affinities to canonical DNA target sequences and present diverse transcriptional activation capacities in vivo. SlCDF1?5 genes exhibited distinct diurnal expression patterns and were differentially induced in response to osmotic, salt, heat, and low-temperature stresses. Arabidopsis plants overexpressing SlCDF1 or SlCDF3 showed increased drought and salt tolerance. In addition, the expression of various stress-responsive genes, such as COR15, RD29A, and RD10, were differentially activated in the overexpressing lines. Interestingly, overexpression in Arabidopsis of SlCDF3 but not SlCDF1 promotes late flowering through modulation of the expression of flowering control genes such as CO and FT. Overall, our data connect SlCDFs to undescribed functions related to abiotic stress tolerance and flowering time through the regulation of specific target genes and an increase in particular metabolites
