Should I stay or should I go? Sibling effects in household formation

This paper analyzes peer effects among siblings in the decision to leave parental home. Estimating peer effects is challenging because of problems of refection, endogenous group formation, and correlated unobservables. We overcome these issues using the exogenous variation in siblings' household formation implied by the eligibility rules for a Spanish rental subsidy. Our results show that sibling effects are negative and that these effects can be explained by the presence of old or ill parents. Sibling effects turn positive from older to younger close-in-age siblings, when imitation is more likely to prevail. Our findings indicate that policy makers who aim at fostering household formation should target the household rather than the individual and combine policies for young adults with policies for the elderly

How Schools Affect Student Well-Being: A Cross-Cultural Approach in 35 OECD Countries

A common approach for measuring the effectiveness of an education system or a school is the estimation of the impact that school interventions have on students’ academic performance. However, the latest trends aim to extend the focus beyond students’ acquisition of knowledge and skills, and to consider aspects such as well-being in the academic context. For this reason, the 2015 edition of the international assessment system Programme for International Student Assessment (PISA) incorporated a new tool aimed at evaluating the socio-emotional variables related to the well-being of students. It is based on a definition focused on the five dimensions proposed in the PISA theoretical framework: cognitive, psychological, social, physical, and material. The main purpose of this study is to identify the well-being components that significantly affect student academic performance and to estimate the magnitude of school effects on the wellbeing of students in OECD countries, the school effect being understood as the ability of schools to increase subjective student well-being. To achieve this goal, we analyzed the responses of 248,620 students from 35 OECD countries to PISA 2015 questionnaires. Specifically, we considered non-cognitive variables in the questionnaires and student performance in science. The results indicated that the cognitive well-being dimension, composed of enjoyment of science, self-efficacy, and instrumental motivation, as well as test anxiety all had a consistent relationship with student performance across countries. In addition, the school effect, estimated through a two-level hierarchical linear model, in terms of student well-being was systematically low. While the school effect accounted for approximately 25% of the variance in the results for the cognitive dimension, only 5–9% of variance in well-being indicators was attributable to it. This suggests that the influence of school on student welfare is weak, and the effect is similar across countries. The present study contributes to the general discussion currently underway about the definition of well-being and the connection between well-being and achievement. The results highlighted two complementary concerns: there is a clear need to promote socioemotional education in schools, and it is important to develop a rigorous framework for well-being assessment. The implications of the results and proposals for future studies are discussed.Spain Ministry of Science, Innovation and Universities PSI2017-85724-P2E Estudios, Evaluaciones e Investigacion, S.

Tree-Growth Variations of Nothofagus antarctica Related to Climate and Land Use Changes in Southern Patagonia, Argentina

Isolated forest patches of Nothofagus antarctica (ñire) are frequent in the Patagonian forest-steppe ecotone. These remnants, also called relicts (R), are separate from the continuous forests (C). Over the past century, these ecotonal forests have been impacted by anthropogenic activities, including fires, logging, and cattle ranching. In order to identify in N. antarctica ring-width records the variations in tree growth associated with documented changes in land use, five sites were selected in Santa Cruz, Argentina. In each site, increment cores from R and C were collected. We developed individual chronologies, and the relationships between regional climate variations and N. antarctica growth were established for each forest type and site. The similarities/differences between site-paired chronologies (R-C) were estimated by calculating moving correlation coefficients lagged by 1 year. N. antarctica regional growth was directly related to precipitation during the current growing season (November–December; r = 0.34, n = 62, p < 0.01), and inversely related to temperature (December–March; r = −0.58, n = 62, p < 0.001). Since the middle of the twentieth century, a progressive decrease has been recorded in regional radial growth, consistent with an increase in summer temperature and a decrease in spring precipitation. In the context of this regional response of N. antarctica to climate, differences in growth patterns between R and C were associated with past changes in land use. Overall, the largest differences between R and C chronologies were concurrent with the settlement of cattle ranches and the associated use of forests. Conversely, similarities between R and C records increased after the establishment of protected areas and during the implementation of similar management practices in both forest types. Our research provides the first dendrochronological records from Nothofagus antarctica for the Argentinean Patagonia and represents one of the first efforts to identify in tree-rings past changes in livestock practices in southern South America.EEA Santa CruzFil: Vettese, Evangelina S.

A academia e a divisão social do trabalho na enfermagem no setor público: aprofundamento ou superação? Academia and the social division of nursing work in the Government sector: sinking or surpassing?

Este artigo parte do pressuposto que o aprofundamento da cisão entre trabalho manual e intelectual na enfermagem acaba por prejudicar as potencialidades inerentes ao trabalho vivo e seu objetivo foi analisar tendências atuais da divisão de trabalho na enfermagem brasileira, exemplificadas por resultados de pesquisas recentes de pós-graduação, que tomaram como objeto diferentes aspectos dos processos de trabalho de assistência, ensino e pesquisa em enfermagem, a partir de uma meta-análise qualitativa. Mostrou-se comum aos três trabalhos a não apropriação do objeto pelos agentes do processo de trabalho: os estudantes de pós-graduação idealizam um recorte do objeto que é modificado pelo orientador segundo sua linha de pesquisa; os relatos das experiências educativas desenvolvidas por enfermeiros mostram a divisão social entre planejamento e execução da atividade, o que impede o esquadrinhamento do objeto do trabalho educativo; os agentes comunitários de saúde executam tarefas indicadas pela equipe de enfermagem. Trata-se de tarefa urgente superar essa alienação por meio da formação e aperfeiçoamento dos sujeitos para que dominem objeto, finalidade e instrumentos do trabalho, para que possam compartilhar seus saberes e solidariamente trabalhar criticamente na transformação dos perfis epidemiológicos das diferentes classes sociais.<br>This paper is based on the assumption that the widening gap between manual labor and intellectual tasks tends to weaken the inherent potential of the labor force. Its purpose is to analyze current trends in the division of labor in the Brazilian nursing sector. This is exemplified by the findings of recent surveys conducted by graduate students who studied various aspects of the work processes involved in healthcare, education and research through a qualitative meta-analysis. The non-appropriation of the object by the work process agents was common to all three studies: the graduate students plan an approach to the object that is altered by the advisor in compliance with research interests; reports on educational experiments conducted by nurses highlight the gap between planning and implementation of the activities, hampering full exploration of the purpose of educational efforts; community health agents perform tasks assigned by the nursing staff. Dealing with this alienation is an urgent task, through training and upgrading the subjects so that they have full mastery of the object, the purpose and the work tools, able to share their expertise and work closely together with a critical approach in order to transform the epidemiological profiles of the various social classes
