Does the prospect of a legalization programme in the US increase unauthorized immigration from Mexico? The logic of the moral hazard of legalization suggests that providing lawful status to undocumented immigrants has the unintended effect of incentivizing further unauthorized immigration. However, we argue and show that concerns about the moral hazard of legalization may be overstated. We conceptualize our argument using two distinct temporal dimensions: a concurrent dimension and a prospective one. Our analysis of the 2007 Mexican Migration Field Research Program (MMFRP) survey provides evidence supporting our arguments. The data show that knowledge regarding a prospective legalization programme in the US does not increase the intent to migrate among prospective migrants. Our results hold when accounting for a range of potential confounding factors, across several multivariate model specifications, and also when analysing comparable respondents who are matched using propensity score matching (PSM) techniques.  相似文献

This paper investigates the relationship between economic and environmental performance with focus on firms in an emerging economy, the Czech Republic, and their CO2 emission reductions. We discuss whether the hypotheses tested for local pollutants that firms emit and firms’ finances are relevant for CO2 emissions. We test the hypotheses on a sample of Czech firms included in the first phase of European Union Emissions Trading Scheme (EU ETS). We observe that introduction of EU ETS did not encourage significant investments in CO2 emissions reduction. Importantly, the results show that the firms that did invest in CO2 reductions experienced a negative impact on their finance. We argue that this is explained by the drop in the price of allowances on the carbon market in 2006 which resulted in firms receiving less revenue from saved allowances than they had expected.  相似文献

Classical sociology addressed the relationship between science and religion, but interest in the topic waned during the 20th century. A second wave of research has emerged in the 21st century, focusing on scientists' (ir)religiosity, evolution, and the relationship between knowledge and acceptance of scientific concepts. Most of this research has been conducted in the United States, used quantitative methods, and focused on creationism, although scholars have recently begun to explore different research methods and sites. Their results suggest that the “conflict thesis” is not valid and that publics and scientists' views tend to be fluid and strongly shaped by national context. The literature on nonreligion has also expanded, but its connection to science remains ripe for further development. A more intersectional approach would also benefit the field, as would increased engagement between public understanding of science scholars and sociologists studying science and religion. Research in both areas is showing that attitudes toward science and religion cannot be understood solely in terms of knowledge about either domain. There is scope for more empirical and theoretical work internationally eschewing the assumption that science and religion conflict and focusing more on identity, culture, and power relations.  相似文献

The constant decline of political trust has been shown in political sociology. Young people in particular seem to display lower levels of political trust, which is a challenge for the sustainability of democracy. Still, these levels of political trust among youth differ greatly from one country to another. This article therefore seeks to answer the following question: How can we account for cross‐national diversity with regard to young people’s political trust? To answer this question, I performed multilevel analyses based on data from the European Social Survey. I show in the article that cross‐national diversity stems from the institutional arrangements that structure entry into adulthood, i.e., what I call ‘youth welfare citizenship regimes’: The more inclusive is the youth economic citizenship and the more individualised is their social citizenship, the higher is young people’s political trust – which could buffer the decline in political trust.  相似文献

We examined the conversations of 14 preschool children to explore differences in communication between friends and nonfriends in a well-established group. Children's social preferences were identified by analysing relative utterance frequencies which revealed a network structure of 4 cliques. We then examined whether the integration (inclusion/exclusion) and social theme (person/action) content of children's utterances, and the responses (accept/oppose) to these utterances, discriminated relationships in the social network. Our main findings were 1) Exclusive utterances were more likely to occur between nonfriends and to be opposed. Inclusive utterances were more likely to occur between friends and to be accepted. 2) Person and action themes were used differentially. In exclusion statements, nonfriends were more likely to be personally rejected whereas friends were more likely to have their actions rejected. In inclusion statements, personal references were more likely to be accepted between friends whereas references to a peer's actions tended to be accepted by both friends and nonfriends. We concluded that children adapted the integration and social theme content of their utterances to relationship context in order to establish more intimate interactions between friends and more distant interactions between nonfriends.  相似文献

The present study was designed to test whether the beneficial effects of emotion regulation (ER) have less to do with the use of singular, ‘adaptive’ strategies and more to do with using a range of strategies. Using a community sample of adolescents (N = 177, M = 13.6 years), groups based on five measures of ER (reappraisal, suppression, concealing, emotional engagement, and adjusting) were created through latent profile analysis. A six‐group model was the best fit. As hypothesized, ER profiles with high scores on one or two indicators were associated with higher levels of internalizing problems, whereas profiles with average to high scores on several indicators and high scores on adjusting were associated with lower levels of internalizing problems (depression, general anxiety, and social anxiety). Results highlight the importance of having different ER strategies to use and that a limited ER repertoire in adolescence may be associated with internalizing problems.  相似文献

In this, article we consider a Bayesian approach to the problem of ranking the means of normal distributed populations, which is a common problem in the biological sciences. We use a decision-theoretic approach with a straightforward loss function to determine a set of candidate rankings. This loss function allows the researcher to balance the risk of not including the correct ranking with the risk of increasing the number of rankings selected. We apply our new procedure to an example regarding the effect of zinc on the diversity of diatom species.  相似文献

Searle and Rudan (1973) derive the inverse of a covariance matrix for unbalanced data in ANOVA. Their expression is highly complicated. This paper presents an alternative derivation and shows how unbalancedness enters in.  相似文献
