Importância concedida à CTSA e Sustentabilidade em Revistas de Investigações Científicas Educacionais no Brasil e Espanha
2016
O objetivo deste estudo é evidenciar a evolução das investigações em educação em ciências no contexto Ciência-Tecnologia-Sociedade voltada para CTSA e Sustentabilidade no último par de décadas (1995–2014), no meio Ibero-americano. Nesse aspecto, foram analisadas as ocorrências de expressões relacionadas a CTSA, Sustentabilidade e outras vinculadas a estes termos em duas revistas de grande impacto e relevância na investigação didática no ensino de ciências e muito utilizadas por docentes e pesquisadores no âmbito dos países Ibero-americanos. Resultados apontam que embora tenha havido mudanças rumo às abordagens CTSA e Sustentabilidade na última década, estas mudanças ainda são tímidas em vir…
Early and midterm outcomes of bioresorbable vascular scaffolds for ostial coronary lesions: insights from the GHOST-EU registry.
2016
Aims: We aimed to investigate the outcomes of bioresorbable vascular scaffolds (BVS) in coronary ostial lesions. Ostial lesions represent a challenging angiographic subset, with higher event rates compared with non-ostial lesions. BVS might be associated with advantages over the long term, but their safety in this setting remains to be explored. Methods and results: Procedural and 12-month follow-up data from consecutive patients treated with BVS for lesions located at the ostium of the right (RCA), left anterior (LAD) or circumflex (LCX) coronary in 11 European centres were collected. The primary device-oriented endpoint was defined as a combination of cardiovascular death, target vessel m…
Globalization and Female Labor Force Participation in Developing Countries: An Empirical (Re-)Assessment
2017
We investigate the impact of foreign direct investment (FDI) and trade, as two measures of globalization, on female labor force participation rate in a sample of 80 developing countries over the time period 1980–2005. Contrary to the mainstream view in the literature, which is mainly based on country-case studies or simple cross-country variation, we find that both, FDI and trade have a generally negative impact on female labor force participation. While the impact is of negligible economic size, it is stronger for younger cohorts, possibly reflecting a higher return to education in open economies. We further find a large degree of cross-regional heterogeneity and that the effect of globali…
Channels through Which Human Capital Inequality Influences Economic Growth
2011
This paper empirically investigates the theoretical predictions of some of the channels through which human capital inequality may discourage investment and growth. In a cross section of countries over the period 1960–2000, findings reveal that, all other things being equal, a greater degree of human capital inequality increases fertility rates and reduces life expectancy, which in turn hampers the accumulation rates of human capital. This effect is reinforced in the countries where individuals find it difficult to access credit. Extensive sensitivity analyses show that the results are robust across specifications and are not driven by atypical observations, endogenous regressors, or unobse…
ICT and Economic Growth
2005
Using new sectoral data on investment and capital services we carry out a growth accounting exercise on Spain 1985-2002. We compute the contribution to output and labour productivity growth of employment, non-ICT and ICT capital, labour qualification and Total Factor Productivity. Results are given for 29 different branches; individually and grouped into four clusters according to their ICT use intensity. Three ICT assets (hardware, communications and software) are considered. We find that although the ICT intensive group appears to be the most dynamic cluster, most of the impact on productivity is still to come. There is some evidence of a reversal of the productivity slow down of the nine…
Executive Incentive Compensation and Economic Prosperity
2008
This paper analyzes the existence of a potential link between the prevalence of long term incentive compensation schemes and the economic prosperity of a country. This issue is previously not addressed in the literature. In a panel regression with fixed effects a strongly significant, positive effect is found between growth of GDP/capita in real terms and this prevalence, while controlling for general investment and institutional variables. However, when the 22 countries of the study are divided into European and non-European, the growth effect found for the entire material accrues only to the non-European countries. It is concluded that long term incentive contracts seem to have no effect …
Gender differences in French undergraduates' academic plans and wage expectations
2016
International audience; Gender differences in wage expectations may affect investment in human capital and increase inequalities in the labour market. Our research based on a survey of first-year students at a French university aims to focus on expectations at the beginning of the career. Our results show that anticipated earnings differ significantly between men and women. One year after graduation, we find a gender gap in pay of 16 percent. A wage decomposition method indicates that most of this effect is due to anticipation of discrimination. Ten years after graduation, anticipated discrimination is still almost as dominant in explaining the gender gap in pay. Finally, using a survey of …
Six-years-long effects of the Italian policies for photovoltaics on the pay-back period of grid-connected PV systems installed in urban contexts
2017
Abstract In this study the discounted pay-back (DPB) period of rooftop photovoltaic (PV) systems installed in urban contexts was investigated during the course of time with the aim of evaluating the effects of the different supporting policies enacted by the Italian government. The profitability of the investment in three Italian cities was observed from June 2010 to May 2016 by means of an exhaustive economic analysis based on the study of the variation of the costs and benefits during the lifetime of the investment. The analysis considered the disbursements for the PV system devices, maintenance and management, insurance, and wear of PV panels and inverters. Other significant parameters, …
Foreign Takeovers and Wages: Theory and Evidence from Hungary
2005
This study discriminates FDI technology spillover from learning effects. Whenever learning takes time, our model predicts that foreign investors deduct the economic value of learning from wages of inexperienced workers and add it to experienced ones to prevent them from moving to local competitors. Hence, the national wage bill is unaffected by foreign takeovers. In contrast to learning, technology spillover effects occur whenever a worker with MNE experience contributes more to local firms' than to MNEs' productivity. In this case, experienced MNE workers are hired by local firms and the host country obtains a welfare gain. We investigate empirically wages, productivity, and worker turnove…
Female Oviposition Decisions and Their Impact on Progeny Life-History Traits
2008
An important factor affecting the life-history of an organism is parental investment in reproduction: reproductive decisions are almost invariably costly. Therefore, reproductive decisions should be beneficial in terms of increased offspring number or fitness. For example, egg laying decisions in many insects can influence resource availability of the offspring through changes in the larval density, and resource availability will have effects on many life-history traits. Here we studied whether female reproductive decisions affect offspring fitness in Callosobruchus maculatus seed beetles. Females laid more eggs on black-eye beans than on mung beans. However, when the difference in the surf…
