Migration, violence and welfare programmes in rural Colombia
Full text linkThis paper studies migration decisions of very poor households in an environment with a high level of violence. By matching detailed retrospective data on violence levels in Colombian rural municipalities with a household survey collected for the evaluation of the "Familias en Acción" welfare programme, the empirical analysis takes into account possible selection problems of the sample and the key issue of endogeneity of violence. The main results show that high levels of violence encourage households to leave their municipality of residence but that welfare programmes may mitigate these flows, provided that the incidence of violence is not unduly high. This is consistent with the fact that the households under study are liquidity constrained: when violence is high, cash transfers may enable them to leave their municipality of residence, whereas, in more normal circumstances, receiving cash transfers increases the benefits to stay where they are registered. Further evidence using household shocks and wealth confirm that liquidity constraints play a large role in explaining such heterogeneous impacts of the programme along violence levels. Other important determinants of migration are the type of property rights and the health insurance rural households can benefit from.migration, welfare programme, violence, displacement, Colombia
Alice Mesnard: Health Risks and Migration
No full text<p>The Population and Poverty (PopPov) Research Network brings together researchers who are examining how population dynamics affect economic outcomes, primarily in African countries. The overarching vision is one of a Network where results, methodological advances, and policy impacts are shared across research teams and eventually translated into policy recommendations.</p>
<p>In this video, Alice Mesnard of City University London describes her research on health risks and migration, a rarely studied topic despite their important consequences for the planning, targeting, and effectiveness of health policies. This research investigates the role of migration in dealing with the risks of chronic and acute illnesses, injuries, hospitalizations, and communicable diseases that may not only affect the health of people but also their economic situation.</p>
<p>PRB informs people around the world about population, health and the environment, and empowers them to use that information to advance the well-being of current and future generations. Find out more about PRB at our website, www.prb.org.</p

Early identification of at-risk youth in Latin America : an application of cluster analysis
Full text linkA new literature on the nature of and policies for youth in Latin America is emerging, but there is still very little known about who are the most vulnerable young people. This paper aims to characterize the heterogeneity in the youth population and identify ex ante the youth that are at-risk and should be targeted with prevention programs. Using non-parametric methodologies and specialized youth surveys from Mexico and Chile, the authors quantify and characterize the different sub-groups of youth, according to the amount of risk in their lives, and find that approximately 20 percent of 18 to 24 year old Chileans and 40 percent of the same age cohort in Mexico are suffering the consequences of a range of negative behaviors. Another 8 to 20 percent demonstrate factors in their lives that pre-dispose them to becoming at-risk youth - they are the candidates for prevention programs. The analysis finds two observable variables that can be used to identify which children have a higher probability of becoming troubled youth: poverty and residing in rural areas. The analysis also finds that risky behaviors increase with age and differ by gender, thereby highlighting the need for program and policy differentiation along these two demographic dimensions.Adolescent Health,Youth and Governance,Health Monitoring&Evaluation,Population Policies,Gender and Health
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
Child education and work choices in the presence of a conditional cash transfer programme in rural Colombia
Full text linkThe paper studies the effects of Familias en Acción, a conditional cash transfer programme implemented in rural areas in Colombia in 2002, on school enrolment and child labour. Using a quasi-experimental approach, our methodology makes use of an interesting feature of the data, which allows us to identify anticipation effects. Our results show that the programme increased school participation of 14 to 17 year old children quite substantially, by between 5 and 7 percentage points, and had lower, but non-negligible effects on enrolment of younger children of between around 1.5 and 2.5 percentage points. In terms of work, the effects are generally largest for younger children whose participation in domestic work decreased by around 10 to 12 percentage points after the programme but whose participation in income-generating work remained largely unaffected by the programme. We also find evidence of school and work time not being fully substitutable, suggesting that some, but not all, of the increased time at school may be drawn from children's leisure time.
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
