Does increasing compulsory education decrease or displace adolescent crime? New evidence from administrative and victimization data
No full textThis article estimates the contemporaneous effect of education on adolescent crime by exploiting the implementation a reform that increases the school leaving age in Italy by 1 year. We find that the Reform increases the enrollment rate of all ages but decreases the offending rate of 14-year-olds only, who are the age group explicitly targeted by the Reform. The effect mainly comes from natives males, while females and immigrants are not affected. The Reform does not induce crime displacement in times of the year or of the day when the school is not in session, but it increases violent crimes at school. By using measures of enrollment and crime, as well as data at the aggregate and individual level, this article shows that compulsory education reforms have a crime-reducing effect induced by incapacitation but may also lead to an increase of crimes in school facilities plausibly due to a higher concentration of students
Birth weight, neonatal care, and infant mortality: Evidence from macrosomic babies
No full textThis study demonstrates that rule-of-thumb health treatment decision-making exists when assigning medical care to macrosomic newborns with an extremely high birth weight and estimates the short-run health return to neonatal care for infants at the high end of the birth weight distribution. Using a regression discontinuity design, we find that infants born with a birth weight above 5000-gram have a 2 percentage-point higher probability of admission to a neonatal intensive care unit and a 1 percentage-point higher probability of antibiotics receipt, compared to infants with a birth weight below 5000-gram. We also find that being born above the 5000-gram cutoff has a mortality-reducing effect: infants with a birth weight larger than 5000-gram face a 0.15 percentage-point lower risk of mortality in the first week and a 0.20 percentage-point lower risk of mortality in the first month, compared to their counterparts with a birth weight below 5000-gram. We do not find any evidence of changes in health treatments and mortality at macrosomic cutoffs lower than 5000-gram, which is consistent with the idea that such treatment decisions are guided by the higher expected morbidity and mortality risk associated with infants weighing more than 5000-gram
Does child care availability play a role in maternal employment and children’s development? Evidence from Italy
No full textThis paper investigates the effects of public child care availability in Italy in mothers’ working status and children’s scholastic achievements. We use a newly available dataset containing individual standardized test scores of pupils attending the second grade of primary school in 2009–2010 in conjunction with data on public child care availability. Our estimates indicate a positive and significant effects of child care availability on both mothers’ working status and children’s Language test scores. We find that a percentage change in public child care coverage increases mothers’ probability to work by 1.3 percentage points and children’s Language test scores by 0.85 percent of one standard deviation; we do not find any effect on Math test scores. Moreover, the impact of a percentage change in public child care on mothers’ employment and children’s Language test scores is greater in provinces where child care availability is more limited

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
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
