Pay Dispersion and Work Performance
No full textWe collected a unique dataset from the Italian soccer league to study the effect of pay dispersion on team performance, under different definitions of what constitutes a “team”. Our results show that when the team is considered to consist of only the players who contribute to the result, high pay dispersion has a detrimental impact on team performance. Enlarging the definition of work team causes this effect to disappear or even become positive. Finally, we find that the detrimental effect of pay dispersion is due to worst individual performance, rather than a
reduction of team cooperation

Risk preferences and personality traits in children and adolescents
No full textWe elicit both risk preferences and personality traits of 340 children aged 7–16 and enrolled in Danish schools: we elicit risk preferences using a modified–and simplified–version of the Bomb Risk Elicitation Task, and to measure personality traits we use the HEXACO (parent-report) questionnaire. Our results show that, on average, children are risk averse, become more risk taking with age, and that girls are, on average, more risk averse than boys. On the contrary, personality traits are stable across ages, except for a slight decrease in Openness to Experience. Personality and risk preferences are not correlated either when looking at raw correlations or regressions, including controls. The results suggest that risk preferences and personality traits are complementary measures of individual heterogeneity of behavior.</p
Fast or Fair?:A Study of Response Times
Full text linkThis paper uses a modified dictator game to investigate the relationship between response times and social preferences. We find that egoistic subjects make faster decisions than subjects with social preferences. Moreover, our within-analysis reveals that, for a given individual, egoistic payoff maximizing decisions are reached quicker than choices expressing social preference
Luck or cheating? A field experiment on honesty with children
No full textWe run an experiment to study the relationship between honesty, age and self-control. We focus on children aged between 5 and 15 as the literature suggests that self-control develops within such age range. We ask each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet. We only reward children who report white. Although we are unable to tell whether each child was honest or not, we speculate about the proportion of reported white outcomes. Children report the prize-winning outcome at rates statistically above 50% but below 100%. Moreover, the probability of cheating is uniform across groups based on child’s characteristics, in particular age. In a second treatment we explicitly tell children not to cheat. This request has a dampening effect on their tendency to over-report the prize-winning outcome, especially in girls. Furthermore, while this effect in boys is constant with age, in girls it tends to decrease with age
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Ecología integral: entre recursos pedagógicos y sostenibilidad
No full text“Hoy se habla con igual insistencia tanto de la destrucción del medioambiente natural como de la fragilidad de los grandes sistemas tecnológicos”14 . Es la crisis de una idea de civilización que parece “suspendida en el abismo, ligada con cuerdas, cadenas y pasarelas” donde todo “al contrario de elevarse, está colgado hacia abajo”15 . El desafío puesto en la sostenibilidad del desarrollo, en lo que se refiere a la cultura y la educación, invierte el discurso pedagógico, su reflexividad práctica, empírica y eidética, con referencia a la formación de la persona y a las tareas de las ciencias para la salvaguardia delo creado
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
