Infidelidade e ciúme no relacionamento amoroso e sexual

RESUMO: O presente estudo tem como objectivo avaliar a relação, por género, entre a infidelidade, o ciúme e a satisfação sexual. Para tal foi utilizada uma amostra de 186 sujeitos, de ambos os sexos, que preencheram um protocolo que incluía como medidas de avaliação um questionário de dados demográficos,um de envolvimentos românticos e sexuais, um de reacções emocionais à infidelidade do parceiro, o Multidimensional Jealousy Scale (Pfeiffer & Wong, 1989), o Big Five Inventory (Benet-Martinez & Oliver, 1998) e o Index Sexual Satisfaction (Hudson, Harrison & Crosscup, 1981). Foram encontradas diferenças entre géneros face à infidelidade, sendo que os homens consideram pior uma infidelidade sexual e as mulheres uma infidelidade emocional. A insatisfação sexual associou-se positivamente ao ciúme, em ambos os sexos, contudo, nas mulheres associou-se positivamente a duas dimensões do ciúme enquanto nos homens apenas se associou a uma. O ciúme associou-se de forma positiva com alguns sentimentos como traição, engano, ódio, rejeição ou desilusão, face à infidelidade, em ambos os sexos, o que parece indicar que ambos os sexos reagem aos dois tipos de infidelidade, contudo diferenciam-se na experiência dos sentimentos a ela associados. ABSTRACT: This study aims to assess the relationship, by gender, between infidelity, jealousy and sexual satisfaction. To this end it was used a sample of 186 individuals of both sexes, who completed a protocol that included evaluating measures such as one questionnaire assessing demographic data, one of sexual and romantic entanglements, and another one of emotional reactions to infidelity of the partner, Multidimensional Jealousy Scale (Pfeiffer & Wong,1989), the Big Five Inventory (Benet-Martinez & Oliver, 1998) and Sexual Satisfaction Index (Hudson, Harrison & Crosscup, 1981). Gender differences were found in relation to infidelity, while men consider worse sexual infidelity, women consider it emotional infidelity. Sexual dissatisfaction was positively associated with jealousy in both sexes, however, in women it was positively associated with the two dimensions of jealousy while in men it was associated with only one. Jealousy was associated positively with some feelings of betrayal, deceit, hate, rejection or disappointment towards infidelity for both sexes, suggesting that both sexes respond to the two types of infidelity, however they differ when experiencing feelings associated with it.

OC/EC ratio observations in Europe: Re-thinking the approach for apportionment between primary and secondary organic carbon

This study explores a large set of OC and EC measurements in PM(10) and PM(2.5) aerosol samples, undertaken with a long term constant analytical methodology, to evaluate the capability of the OC/EC minimum ratio to represent the ratio between the OC and EC aerosol components resulting from fossil fuel combustion (OC(ff)/EC(ff)). The data set covers a wide geographical area in Europe, but with a particular focus upon Portugal, Spain and the United Kingdom, and includes a great variety of sites: urban (background, kerbside and tunnel), industrial, rural and remote. The highest minimum ratios were found in samples from remote and rural sites. Urban background sites have shown spatially and temporally consistent minimum ratios, of around 1.0 for PM(10) and 0.7 for PM(2.5).The consistency of results has suggested that the method could be used as a tool to derive the ratio between OC and EC from fossil fuel combustion and consequently to differentiate OC from primary and secondary sources. To explore this capability, OC and EC measurements were performed in a busy roadway tunnel in central Lisbon. The OC/EC ratio, which reflected the composition of vehicle combustion emissions, was in the range of 03-0.4. Ratios of OC/EC in roadside increment air (roadside minus urban background) in Birmingham, UK also lie within the range 03-0.4. Additional measurements were performed under heavy traffic conditions at two double kerbside sites located in the centre of Lisbon and Madrid. The OC/EC minimum ratios observed at both sites were found to be between those of the tunnel and those of urban background air, suggesting that minimum values commonly obtained for this parameter in open urban atmospheres over-predict the direct emissions of OC(ff) from road transport. Possible reasons for this discrepancy are explored. (C) 2011 Elsevier Ltd. All rights reserved.

Dimensionamento da população de cães e gatos do interior do Estado de São Paulo

OBJETIVO: Estimar a população total de cães e a de gatos com proprietário, visando ao melhor planejamento das ações de controle das doenças que envolvam esses animais. MÉTODOS: O estudo foi realizado no interior do Estado de São Paulo, no período de maio a dezembro de 2002. Foram pesquisados 41 municípios e 100 setores censitários, sorteados por amostragem probabilística, estratificada, por conglomerados em dois estágios. Os estratos foram formados agrupando-se os municípios segundo tamanho da população e condições de vida. Para obter os dados da população canina, foi utilizada a Técnica Pasteur São Paulo, desenvolvida para estimar e classificar os cães segundo graus de dependência e restrição. RESULTADOS: Foram visitados 20.958 domicílios e em 52,6% deles o morador possuía cão. A média de cães por domicílio foi de 1,6. Em relação aos gatos, foram encontrados 4.624 deles, concentrados em 12,6% dos domicílios. Os resultados obtidos apontam para a relação cão/habitante de 1:4,0 e de gato/habitante de 1:16,4. CONCLUSÕES: As razões animal/habitante observadas foram bem mais elevadas do que o esperado. Ao serem incorporadas na avaliação da campanha de vacinação contra raiva canina, evidenciaram padrões mais reais de cobertura, levando à rediscussão das metas de vacinação dos municípios. Foi constatada a existência de associação entre o tamanho do município ou condições de vida da população e o nível de restrição dos cães.

A new wader, Recurvirostridae (Charadriiformes), from the early Eocene of Portugal

A new wader (Aves, Charadriiformes, Recurvirostridae) from the Early Eocene site of Silveirinha, in Lower Mondego region, Central Portugal, is described. Comparisons have been made with other forms, both extant and fossil; its affmities are discussed. Silveirinha wader is ascribed to Fluviatilavis antunesi, n. gen. n. sp.

Association between food assistance program participation and overweight

OBJECTIVE The objective of this study was to investigate the association between food assistance program participation and overweight/obesity according to poverty level. METHODS A cross-sectional analysis of data from 46,217 non-pregnant and non-lactating women in Lima, Peru was conducted; these data were obtained from nationally representative surveys from the years 2003, 2004, 2006, and 2008-2010. The dependent variable was overweight/obesity, and the independent variable was food assistance program participation. Poisson regression was used to stratify the data by family socioeconomic level, area of residence (Lima versus the rest of the country; urban versus rural), and survey year (2003-2006 versus 2008-2010). The models were adjusted for age, education level, urbanization, and survey year. RESULTS Food assistance program participation was associated with an increased risk of overweight/obesity in women living in homes without poverty indicators [prevalence ratio (PR) = 1.29; 95% confidence interval (CI) 1.06;1.57]. When stratified by area of residence, similar associations were observed for women living in Lima and urban areas; no associations were found between food assistance program participation and overweight/obesity among women living outside of Lima or in rural areas, regardless of the poverty status. CONCLUSIONS Food assistance program participation was associated with overweight/obesity in non-poor women. Additional studies are required in countries facing both aspects of malnutrition.

A simple approach to numerical modelling of propane combustion in fluidized beds

A mathematical model is proposed for the evolution of temperature, chemical composition, and energy release in bubbles, clouds, and emulsion phase during combustion of gaseous premixtures of air and propane in a bubbling fluidized bed. The analysis begins as the bubbles are formed at the orifices of the distributor, until they explode inside the bed or emerge at the free surface of the bed. The model also considers the freeboard region of the fluidized bed until the propane is thoroughly burned. It is essentially built upon the quasi-global mechanism of Hautman et al. (1981) and the mass and heat transfer equations from the two-phase model of Davidson and Harrison (1963). The focus is not on a new modeling approach, but on combining the classical models of the kinetics and other diffusional aspects to obtain a better insight into the events occurring inside a fluidized bed reactor. Experimental data are obtained to validate the model by testing the combustion of commercial propane, in a laboratory-scale fluidized bed, using four sand particle sizes: 400–500, 315–400, 250–315, and 200–250 µm. The mole fractions of CO2, CO, and O2 in the flue gases and the temperature of the fluidized bed are measured and compared with the numerical results.

Increase in cases of malaria in Mozambique, 2014: epidemic or new endemic pattern?

ABSTRACT OBJECTIVE To describe the increase in cases of malaria in Mozambique. METHODS Cross-sectional study conducted in 2014, in Mozambique with national weekly epidemiological bulletin data. I analyzed the number of recorded cases in the 2009-2013 period, which led to the creation of an endemic channel using the quartile and C-Sum methods. Monthly incidence rates were calculated for the first half of 2014, making it possible to determine the pattern of endemicity. Months in which the incidence rates exceeded the third quartile or line C-sum were declared as epidemic months. RESULTS The provinces of Nampula, Zambezia, Sofala, and Inhambane accounted for 52.7% of all cases in the first half of 2014. Also during this period, the provinces of Nampula, Sofala and Tete were responsible for 54.9% of the deaths from malaria. The incidence rates of malaria in children, and in all ages, have showed patterns in the epidemic zone. For all ages, the incidence rate has peaked in April (2,573 cases/100,000 inhabitants). CONCLUSIONS The results suggest the occurrence of an epidemic pattern of malaria in the first half of 2014 in Mozambique. It is strategic to have a more accurate surveillance at all levels (central, provincial and district) to target prevention and control interventions in a timely manner.
