Health (Health) , 2013, DOI: 10.4236/health.2013.512265
Abstract:


Introduction: Studies on attitudes and practices are increasingly used but not specifically related to the motivations for the use of reproductive health care among women of fertile age, living in urban areas and in different social contexts. Objectives: The aim of this study was to estimate the associations between the variables of social status (degree of poverty in the studied groups) and the variables of fecundity (representations, tensions, practices and control of fertility) and, in addition, to compare access to health care in the different studied groups, assessing the association between use of maternal health care and poverty in urban areas. Design: A case-control study was conducted in the Municipality of Lisbon, Portugal, with a total sample of 1513 women of fertile age: 499 cases of women considered very poor were selected from the database of beneficiaries of RSI (Social Welfare Payment for Inclusion); 1014 controls (two controls for each selected case), divided as 507 poor women selected from the other beneficiaries of Santa Casa da Misericórdia in Lisbon and 507 non-poor women selected from four Health Centers from the Municipality of Lisbon, Portugal. A total of 1054 women answered the questionnaire: 304 cases (response rate of 61%) and 750 (response rate of 74%) controls. The statistical analysis involved descriptive analysis and multinomial logistic regression. Results: The analysis confirms the association between poverty and patterns and representations of fecun

dity regarding pregnancy planning. The results of this study thus show the existence of different distributions on several variables and the gradients of poverty. Regarding access to health care, the major impact of poverty on women

Menopausa, sintomas de menopausa e depress?o: Influência do nível educacional e de outras variáveis sociodemográficas
Fagulha,Teresa; Gonalves,Bruno;
Psicologia , 2005,
Abstract: this study is based on the data collected in an investigation regarding the primary health care patients. the results relating to a sample of 127 women with ages ranging between 35 and 65 years of age are analyzed. all these women answered a questionnaire concerning the perceived menopause status and the menopause symptomatology and participated in a structured clinical interview, in which the presence of various forms of depression according to the dsm?iv criteria was analyzed. they also answered a questionnaire concerning the perceived menopause status as well as symptoms or alterations related with menopause. the frequency of the symptomatology related with menopause is studied and its variation in relation to the level of education, and other sociodemographic variables is analyzed. the relationship between the perceived menopause status and the depressive symptomatology is also studied, taking into consideration the level of education.

Topical differences between Chinese language Twitter and Sina Weibo
Qian Zhang,Bruno Gonalves
Computer Science , 2015,
Abstract: Sina Weibo, China's most popular microblogging platform, is currently used by over $500M$ users and is considered to be a proxy of Chinese social life. In this study, we contrast the discussions occurring on Sina Weibo and on Chinese language Twitter in order to observe two different strands of Chinese culture: people within China who use Sina Weibo with its government imposed restrictions and those outside that are free to speak completely anonymously. We first propose a simple ad-hoc algorithm to identify topics of Tweets and Weibo. Different from previous works on micro-message topic detection, our algorithm considers topics of the same contents but with different \#tags. Our algorithm can also detect topics for Tweets and Weibos without any \#tags. Using a large corpus of Weibo and Chinese language tweets, covering the period from January $1$ to December $31$, $2012$, we obtain a list of topics using clustered \#tags that we can then use to compare the two platforms. Surprisingly, we find that there are no common entries among the Top $100$ most popular topics. Furthermore, only $9.2\%$ of tweets correspond to the Top $1000$ topics on Sina Weibo platform, and conversely only $4.4\%$ of weibos were found to discuss the most popular Twitter topics. Our results reveal significant differences in social attention on the two platforms, with most popular topics on Sina Weibo relating to entertainment while most tweets corresponded to cultural or political contents that is practically non existent in Sina Weibo.
Dieselization and Road Transport CO2 Emissions: Evidence from Europe  [PDF]
António Cardoso Marques, Bruno Miguel Gonalves, José Alberto Fuinhas
Low Carbon Economy (LCE) , 2012, DOI: 10.4236/lce.2012.33008
Abstract: Road transport carbon dioxide emissions were analyzed, by focusing on a panel of 14 European countries for the time span 1995-2007. We deal with the existence of contemporaneous correlation by using the Panel Corrected Standard Errors estimator. We extend the empirical literature by controlling the effect of new diesel passenger car registrations and the average power of those vehicles. The price of gasoline and income reduce road transport carbon dioxide emissions, while population density and average power of new diesel passenger cars raises those emissions. We deepen the debate about dieselization, concluding that saving emissions by using diesel tend to be surpassed by the increased kilometers driven.
Modeling Users' Activity on Twitter Networks: Validation of Dunbar's Number
Bruno Gonalves, Nicola Perra, Alessandro Vespignani
PLOS ONE , 2011, DOI: 10.1371/journal.pone.0022656
Abstract: Microblogging and mobile devices appear to augment human social capabilities, which raises the question whether they remove cognitive or biological constraints on human communication. In this paper we analyze a dataset of Twitter conversations collected across six months involving 1.7 million individuals and test the theoretical cognitive limit on the number of stable social relationships known as Dunbar's number. We find that the data are in agreement with Dunbar's result; users can entertain a maximum of 100–200 stable relationships. Thus, the ‘economy of attention’ is limited in the online world by cognitive and biological constraints as predicted by Dunbar's theory. We propose a simple model for users' behavior that includes finite priority queuing and time resources that reproduces the observed social behavior.
Tecendo a colcha de retalhos: a bricolagem como alternativa para a pesquisa educacional
Neira, Marcos Garcia;Lippi, Bruno Gonalves;
Educa??o & Realidade , 2012, DOI: 10.1590/S2175-62362012000200015
Abstract: the intensity of the current social changes has confronted the modernity legacy. the truths produced by the modern science have been under strong uncertainties. even the way to produce knowledge is questioned nowadays. amongst the emerging alternatives, there is the bricolage. the bricoleurs use a variety of methods, instruments and theoretical references that make possible to access and build interpretations from various places. driven by the cultural studies, denounce the relationship of power that influence the scientific speeches put in course. the present article discusses the presumptions and methodological procedures, and offers an example of educational research inspired in the bricolage.
A depress?o nas mulheres de meia?idade: estudo sobre as utentes dos cuidados de saúde primários

Psicologia , 2005,
Abstract: this study is based on the data collected in an investigation regarding primary health care patients. the prevalence of depressive disorders is studied in a sample of women with ages ranging between 35 and 65 years. all women (n = 179) responded to the center for epidemiologic studies depression scale (ces?d), and 127 agreed to participate in a structured clinical interview adapted from the evaluation of mood disorders section of the structured clinical interwiew for dsm?iv axis i disorders (scid?i) in order to evaluate the presence of various forms of depression according to the dsm?iv criteria. it was verified that 13% of these women met the criteria for the diagnosis of a major depressive episode, 19% met the criteria for dysthymic disorder and 5,5% met the criteria proposed for a minor depressive episode. the relation of age, education level, marital status, work for pay, having children, children at home, dependent children and other socio-?demographic variables with the rate of depressive disorders is studied.
Automatic system for counting cells with elliptical shape
Wesley Nunes Gonalves,Odemir Martinez Bruno
Computer Science , 2012,
Abstract: This paper presents a new method for automatic quantification of ellipse-like cells in images, an important and challenging problem that has been studied by the computer vision community. The proposed method can be described by two main steps. Initially, image segmentation based on the k-means algorithm is performed to separate different types of cells from the background. Then, a robust and efficient strategy is performed on the blob contour for touching cells splitting. Due to the contour processing, the method achieves excellent results of detection compared to manual detection performed by specialists.
