Abstract: There is little evidence on the relationship between leisure-time physical activity (LTPA) and built environment in Brazil, especially in areas of low socioeconomic status. The objective of this study was to describe indicators of built environment score related to LTPA for adults living in a region of low socioeconomic status. We conducted a cross-sectional study of 767 adults living in Ermelino Matarazzo district in S o Paulo, 2007. The dependent variable was the practice of LTPA (in minutes per week). Independent variables were 35 environment variables that were evaluated by an audit instrument in 30 census tracts. LTPA was correlated (Spearman coefficient) with all environment variables, and variables that had p<0.20 were selected to compose two scores (variables with p<0.05 had weight value of 2): Infrastructure (score 1) and Safety for commuting (score 2). Both scores were divided in quintiles and the built environment was composed by the sum of the quintiles of these scores, ranging from 2 to 10 points. Quartiles of built environment were calculated and the first was considered as the most adequate environment for LTPA. The built environment score had 14 variables significantly associated with LTPA and were considered as important attributes for this leisure practice.

Abstract: objective: to identify the prevalence and factors associated with negative self-rated health among adolescents in the state of santa catarina, brazil. methods: a cross-sectional investigation was conducted with a representative sample of 5,028 adolescents who were attending public highschools. the negative self-rated health was analyzed in relation to the following variables: gender, income, physical activity practice, smoking, alcohol consumption, drug use and self-rated stress. the binary logistic regression was carried out to test associations. results: the prevalence of negative self-rated health was higher among girls (17.6%) in comparison to boys (9.6%; p<0.0001). higher values of odds ratio (or) were associated with female gender (or 1.99; 95%ci 1.66-2.38), lower socioeconomic status (or 1.54; 95%ci 1.08-2.20), smoking (or 2.00; 95%ci 1.35-2.94), and negative self-rated stress (or 3.36; 95%ci 2.74-4.12). conclusions: female adolescents, those with lower socioeconomic status, smokers and those who negatively perceived stress presented higher levels of negative self-rated health.
Human Friendly Interface Design for Virtual Fitting Room Applications on Android Based Mobile Devices  [PDF]
Cecilia Garcia Martin, Erdal Oruklu
Journal of Signal and Information Processing (JSIP) , 2012, DOI: 10.4236/jsip.2012.34061
Abstract: This paper presents an image processing design flow for virtual fitting room (VFR) applications, targeting both personal computers and mobile devices. The proposed human friendly interface is implemented by a three-stage algorithm: Detection and sizing of the user's body, detection of reference points based on face detection and augmented reality markers, and superimposition of the clothing over the user's image. Compared to other existing VFR systems, key difference is the lack of any proprietary hardware components or peripherals. Proposed VFR is software based and designed to be universally compatible as long as the device has a camera. Furthermore, JAVA implementation on Android based mobile systems is computationally efficient and it can run in real-time on existing mobile devices.
Poisson loglinear modeling with linear constraints on the expected cell frequencies
Nirian Martin,Leandro Pardo
Statistics , 2010, DOI: 10.1007/s13571-012-0035-2
Abstract: In this paper we consider Poisson loglinear models with linear constraints (LMLC) on the expected table counts. Multinomial and product multinomial loglinear models can be obtained by considering that some marginal totals (linear constraints on the expected table counts) have been prefixed in a Poisson loglinear model. Therefore with the theory developed in this paper, multinomial and product multinomial loglinear models can be considered as a particular case. To carry out inferences on the parameters in the LMLC an information-theoretic approach is followed from which the classical maximum likelihood estimators and Pearson chi-square statistics for goodness-of fit are obtained. In addition, nested hypotheses are proposed as a general procedure for hypothesis testing. Through a simulation study the appropriateness of proposed inference tools is illustrated.
Misticismo do cálculo e a ascese consumista: raz?o e fé no "crer sem pertencer" e no neopentecostalismo
Totaro, Paolo;
Religi?o & Sociedade , 2010, DOI: 10.1590/S0100-85872010000100005
Abstract: the calculation culture engenders two forms of individualization: a) isolation of individuals in steps of formalized processes, i.e. in repetitive cycles of consumption and in organizational logic of bureaucracy; which puts self in a condition of heteronomy. b) freedom of men to obtain the possibility to control physical and economical nature by mathematical calculation, which develops a condition of autonomy of the self. in this latter form, the calculation ends up matching its own limits so that it is destined to act on the border-line of mysticism. the most important present-day forms of religious deinstitutionalization, which were the neo-pentecostal movements (with their consumerist accents), and the so-called "enchanted secularization" (with its mystic horizons), refer to those two forces of calculation culture.
