Although being a very popular sport in many countries, soccer has not received much attention from the scientific community. In this paper, we study soccer from a complex network point of view. First, we consider a bipartite network with two kinds of vertices or nodes: the soccer players and the clubs. Real data were gathered from the 32 editions of the Brazilian soccer championship, in a total of 13 411 soccer players and 127 clubs. We find a lot of interesting and perhaps unsuspected results. The probability that a Brazilian soccer player has worked at N clubs or played M games shows an exponential decay while the probability that he has scored G goals is power law. Now, if two soccer players who have worked at the same club at the same time are connected by an edge, then a new type of network arises (composed exclusively by soccer player nodes). Our analysis shows that for this network the degree distribution decays exponentially. We determine the exact values of the clustering coefficient, the assortativity coefficient and the average shortest path length and compare them with those of the Erdös-Rényi and configuration model. The time evolution of these quantities are calculated and the corresponding results discussed.

This paper presents new data on agricultural production, the palaeoenvironment and social change during the Bronze Age of southeast Spain. The authors argue against the inference of irrigation as the basis for agriculture and relate the emergence of cereal monoculture to the extraction of surplus and the exploitation of human labour.

The objective of this study was to evaluate the perception of the elderly residents of a long-stay nursing home on the process of institutionalization. We interviewed 14 subjects, five women and nine men, aged between 60 and 92 years. Data collection was conducted with a semi-structured sociodemographic interview, which presented the guiding question: “Tell me about how is your life, what do you do and how did you come to live here”. From the analysis, we found topics related to feelings of abandonment, loneliness, anger, ingratitude, living with chronic pain, satisfaction of property in the nursing home, productivity and social relationship. Given the thematic analysis, it was possible to group them into three categories such as: what the elderly feel, what the elderly perceive and what the elderly desire. As a result, we need public policies that addresses to the service provided by institutions regarding elderly expectations.

Objective: to estimate the prevalence of the probability of common mental disorders among abusers of alcohol and other drugs.Method: a cross-sectional study. The sample was made up of 234 individuals undergoing treatment and rehabilitation for chemical dependence in private clinics and in a Psychosocial Care Center in the Southeast area of the state of Goiás, Brazil. Instruments on sociodemographic profile, use of licit and/or illicit drugs, and a questionnaire that tracks common mental suffering were applied.Results: the outcome variable was the probability of common mental disorder, with 37.2% of the total of the sample. Association between the probability of common mental disorders and the female gender (odds ratio=4.06; 95% CI 1.56-10.56), age ≤25 years old (odds ratio=3.00; 95% CCI 1.41-6.38), and use of marijuana in life (odds ratio=2.83; 95% CI 1.38-5.78) were found. Conclusion: the study showed an association between the use and abuse of drugs and risk for common mental disorders. DESCRIPTORS:Substance-related disorders. Psychiatric nursing. Prevalence.

Factors associated with the probability of common mental disorders in pregnant women: a cross-sectional study AbstrActObjective: To estimate the prevalence of probability of common mental disorders in pregnant women and associated factors. Methods:A cross-sectional study with a quantitative and descriptive approach was performed with 330 pregnant women enrolled in a Women's Health Service located in Mid-West Brazil. Data were obtained through a questionnaire about socio-demographic characteristics and family or personal history. The Self-Reporting Questionnaire and Poisson regression were applied to screen for common mental disorders, aiming to identify factors associated with it. Results: The prevalence of probability of common mental disorders among pregnant women was 57.1% and it was associated with marital status, gestational age, unplanned pregnancy and bleeding. Conclusion: The prevalence of pregnant women likely to have common mental disorders and the average Self-Reporting Questionnaire score estimated in this study were higher than those found in other studies with samples from the general population.

In recent years there has been considerable interest in the structure and dynamics of complex networks. One of the most studied networks is the linear Barabási-Albert model. Here we investigate the nonlinear Barabási-Albert growing network. In this model, a new node connects to a vertex of degree k with a probability proportional to k α (α real). Each vertex adds m new edges to the network. We derive an analytic expression for the degree distribution P (k) which is valid for all values of m and α ≤ 1. In the limit α → −∞ the network is homogeneous. If α > 1 there is a gel phase with m super-connected nodes. It is proposed a formula for the clustering coefficient which is in good agreement with numerical simulations. The assortativity coefficient r is determined and it is shown that the nonlinear Barabási-Albert network is assortative (disassortative) if α < 1 (α > 1) and no assortative only when α = 1. In the limit α → −∞ the assortativity coefficient can be exactly calculated. We find r = 7 13 when m = 2. Finally, the minimum average shortest path length lmin is numerically evaluated. Increasing the network size, lmin diverges for α ≤ 1 and it is equal to 1 when α > 1.

OBJECTIVE Estimate the prevalence and determinants of tobacco use by students.METHODS This cross-sectional study, carried out between 2013 and 2014, evaluates 701 public school students between 10 and 79 years of age living in a city in the countryside of the State of Goias, Midwest of Brazil. A structured questionnaire collected the data and the predictor variables were demographic data, family nucleus, religion, physical activity practice, family functionality and parental smoking. Two multivariable models were implemented, the first for occasional tobacco use and the second for regular use, acquiring the measure of prevalence ratio (PR) and their respective 95%CI. Variables with p < 0.10 were included in Poisson regression models with robust variance to obtain the adjusted PR (adPR) and 95%CI. The Wald Chi-Squared test examined the differences between proportions, and values with p < 0.05 were statistically significant.RESULTS The prevalence of occasional and regular tobacco use were 33.4% (95%CI 29.8–36.9) and 6.7% (95%CI 5.0–8.8), respectively. The factors associated with occasional tobacco consumption were age of 15 to 17 years (adPR = 1.98) and above 18 years (adPR = 3.87), male gender (adPR = 1.23), moderate family dysfunction (adPR = 1.30), high family dysfunction (adPR = 1.97) and parental smoking (adPR = 1.60). In regards to regular consumption of tobacco, age above 18 years (adPR = 4.63), lack of religion (adPR = 2.08), high family dysfunction (adPR = 2.35) and parental smoking (adPR = 2.89) remained associated.CONCLUSIONS Students exhibit a high prevalence of occasional and regular tobacco use. This consumption relates to sociodemographic variables and family dysfunction.

Field research and predictive modelling of global warming and desertification by environmental scientists in the Mediterranean has concentrated on the short term. In this paper, it is argued that collaboration between the historical sciences, especially archaeology, and the environmental sciences can provide a longer-term perspective on desertification in the Mediterranean. Such collaboration has taken place recently in the Vera basin (Almería, south-east Spain), with the financial support of the European Union. Details of the archaeological and historical sequences of occupation in the basin are given, before presenting the main trends in demography, settlement and political systems from 4000 BC until the present day. This is followed by details of the long-term record of degradation in the Vera basin. The paper concludes by using the long-term record to propose recommendations for the future management of this landscape.
