The joy of ruling: an experimental investigation on collective giving

We analyse team dictator games with different voting mechanisms in the laboratory. Individuals vote to select a donation for all group members. Standard Bayesian analysis makes the same prediction for all three mechanisms: participants should cast the same vote regardless of the voting mechanism used to determine the common donation level. Our experimental results show that subjects fail to choose the same vote. We show that their behaviour is consistent with a joy of ruling: individuals get an extra utility when they determine the voting outcome.     

From the Replacement Rate to the Synthetic Indicator: A Global and Gender Measure of Pension Adequacy in the European Union

To measure the adequacy of pension systems in the world, one of the most commonly used indicators is the Replacement Rate. Our work is based on the statement that this indicator is imperfect itself to measure adequacy because it does not collect the multiple dimensions that it involves while being a static measurement. Consequently and based on the data provided by “The 2015 Pension Adequacy Report: current and future income adequacy in old age in the European Union” of the European Commission, in this paper we select a set of variables that are considered representative to measure the adequacy of pension systems from a dynamic and multidimensional perspective, and based on them, a synthetic adequacy indicator is developed. This indicator aims to compare European pension systems from the adequacy objective and to carry out continuous monitoring of the effects that the reform processes may have on the adequacy of pensions. The analysis is completed with the calculation of a gender indicator on pension adequacy for the European Union (EU-28) which identifies the still existing gap between men and women.     

Connectivity and Resilience: A Multidimensional Analysis of Infrastructure Impacts in the Southwestern Amazon

Infrastructure is a worldwide policy priority for national development via regional integration into the global economy. However, economic, ecological and social research draws contrasting conclusions about the consequences of infrastructure. We present a synthetic approach to the study of infrastructure, focusing on a multidimensional treatment of indicators of connectivity and resilience. As our study case, we adopt a tri-national frontier in the southwestern Amazon being integrated by a highway, and use survey data for rural leaders to evaluate the relationship of community connectivity to market towns and social-ecological resilience. The findings show varying relationships among different dimensions of connectivity and resilience, which bear implications regarding indicator approaches to the study of infrastructure impacts.     

Mitigating the political participation gap from the school: the roles of civic knowledge and classroom climate

Empirical evidence has consistently shown that political participation is positively related with socioeconomic background. Furthermore, recent research suggests that children who come from low status families are already less willing to get politically involved. The present paper aims to analyze the possible impact that schools can have in mitigating the effect of parents' socioeconomic status on students' expected electoral participation, focusing on two variables: civic knowledge and classroom climate. The analyses are based on a series of multilevel models using Chilean data of the International Civic and Citizenship Education Study 2009. The results support the influence of students' socioeconomic background on expected electoral participation. Furthermore, civic knowledge and classroom climate show a positive and similar influence on students' expected participation. However, classroom climate appears less affected by students' background than civic knowledge, opening the discussion about which strategy should be emphasized when aiming to mitigate the political participation gap.     

Motivational factors and physician advice for physical activity in older urban adults

This study aimed to ascertain by means of a new scale older adults' motives for engaging in physical activity, in a probability and representative sample of an older urban population. The sample size was 630 older adults, ranging from 65 to 94 years in age, randomly selected using multistage sampling. The participants completed a 17-item questionnaire, as well as answering questions on demographic variables, type of demand for physical activity, and physician's recommendation. A principal-component analysis was performed. The relationships among the four factors (physical health, social relationships, competence, and physician's advice) show a clearly motivational structure. Significant relationships have also been found between physician's recommendation and type of demand. The findings suggest that programs promoting physical activity in older adults should have different characteristics from those aimed at general adult populations.     

The relationship between non-marital fathers' social networks and social capital and father involvement

Literature and research examining father involvement has focused primarily on outcomes associated with the well-being and development of children. Receiving limited attention in this literature has been the examination of the contextual factors associated with fathers and how these factors shape fathers' involvement with their young children. Addressing this limitation, this study focuses on the intra- and interdependent networks non-marital fathers maintain and utilize in fulfilling their parental responsibilities of father involvement. Results of the regression models indicate that non-marital fathers' relationship with their former spouse or partner and involvement with informal networks is positively associated with their involvement with young children. Policy and practice implications are discussed.     

Is It Considered Violence? The Acceptability of Physical Punishment of Children in Europe

This study analyzes correlates of the acceptability of physical punishment of children in Europe. The design was a three‐level ordinal logistic regression of 10,812 people nested within 208 localities (cities), nested within 14 countries of the European Union. Results showed that higher levels of acceptability were reported by men, the older, the less educated, and those who perceived that violence against children was less frequent in their own country. At the country level, the existence of laws prohibiting physical punishment of children as well as a lower number of child maltreatment deaths were significantly associated with lower levels of acceptability of physical punishment of children. Findings suggest that education efforts at the individual and population level are needed.     

M-estimators for isotonic regression

In this paper we propose a family of robust estimates for isotonic regression: isotonic M-estimators. We show that their asymptotic distribution is, up to an scalar factor, the same as that of Brunk's classical isotonic estimator. We also derive the influence function and the breakdown point of these estimates. Finally we perform a Monte Carlo study that shows that the proposed family includes estimators that are simultaneously highly efficient under Gaussian errors and highly robust when the error distribution has heavy tails.     

Loving and living the Zapatista event: understanding affect inside youth Mexican activism

This paper will detail youth political engagement in one of the most important activist organisations that the Mexican city of Puebla (the fourth largest in the country) has known in its recent history. In particular, the paper will focus on the leadership of two of the leaders of this organisation, who were also lovers. As we will see, the relationship between these two activists proved to be very important for this organisation, so much so that when the couple broke up, the entire collective collapsed. In this sense, the theoretical challenge I am interested in is the one of inserting the study of the affective dimension of youth political practices in the social and political contexts in which these practices make sense. It is hoped that by studying this case in a rather explorative way, we will gain a better understanding of how youth politics and engagement interact with interpersonal affect.     

Study about upper limb on highly repetitive work in maquila operations

Industrial work is a very active sector in the economy of countries; an important part of people's work is done using the upper extremities. The purpose of this project is to characterize the effect of upper extremity work, analyze its relationship with the hand strength and the presence of fatigue and develop a model with the ability to estimate recovery times for the shoulder using variables different from the biomechanical variables.
