Traditionally, immigrants’ propensity to naturalize is attributed to individual characteristics and the origin country. Recently scholars increasingly recognise that naturalisation decisions do not take place in a vacuum: they are conditioned both by the individual life course of immigrants, such as the age at migration and family situation, as well as the opportunity structure set by citizenship policies of the destination country. Yet it is less clear what impact specific policy changes have, and to whom these changes matter most. In this paper we address these questions by analysing citizenship acquisition among first generation immigrants in the Netherlands in light of a restriction in citizenship policy in 2003. We employ unique micro-level longitudinal data from Dutch municipal population registers between 1995 until 2012, which allow us to track naturalisation among different immigration cohorts. We find evidence that indeed naturalisation is part of a larger life course trajectory: immigrants who arrive at a younger age in the Netherlands naturalise more often and so do immigrants with a native partner, or a foreign-born partner who also naturalises. Policy also matters: migrants naturalise later and less often under more restrictive institutional conditions, especially migrants from less developed and politically unstable countries of origin.  相似文献

Abstract Because consumer opinions to an increasing extent affect the structure and management of the U.S. food system, it is important for social scientists to accurately model consumer trust in this system so they can better understand and anticipate public responses to existing or proposed food‐related regulatory policies and facilitate effective partnership building between food‐system representatives and the public. The recreancy theorem posits that individuals' trust in and support for societal institutions reflects their perceptions of the competence and fiduciary responsibility of institutional actors. This theorem might prove effective at identifying the key determinants of consumers' trust in and support for institutional actors within the U.S. food system, whether these actors be representatives of large‐scale, internationally operated firms or small‐scale, locally operated businesses. We used data from two nationwide samples of adults to test the recreancy theorem for seven to nine pertinent institutional actors each within five areas of the U.S. food system: food safety, nutrition, treatment of workers, environmental protection, and treatment of livestock. The resulting 55 tests of the theorem entailed the estimation of 55 structural equation models to evaluate model fit and the efficacy of perceived competence and fiduciary responsibility in explaining trust and support. The results of analyzing the structural equation models separately and overall indicate support for the recreancy theorem. Based upon our results, we offer suggestions for enhancing public‐private partnership formation within the U.S. food system.  相似文献

The Second Generation in Europe   总被引:1,自引:0,他引:1  
The study of integration processes has now reached a crucial stage in most Western European countries with the emergence of the second generation. The oldest children born to postwar immigrants on European soil have recently entered the job market, and we can now investigate their performance in both education and employment. This opens a unique opportunity to compare the situations of second generation migrants across countries. Ostensibly the children all have the same starting position, being born in the country of settlement. The intriguing question is how differences between immigrant groups, and also differences in national contexts, work to the benefit or detriment of the second generation. We discuss the first issue briefly, confining ourselves here to Turkish and Moroccan immigrants. In addressing the issue of national contexts, we focus primarily on policies and practices rather than on broad‐reaching national integration models. We examine in detail the integration process itself in the context of vital institutional arrangements such as the education system and the mechanisms for transition to the labor market. How do such arrangements differ between countries, and how do they affect the outcomes for the second generation?  相似文献

Can citizenship improve the economic integration of immigrants, and if so, how? Scholars traditionally understand a citizenship premium in the labour market, besides access to restricted jobs, as the result of a positive signal of naturalisation towards employers. While we do not discard these mechanisms, we argue that explanations should also take into account that migrants anticipate rewards and opportunities of naturalisation by investing in their human capital development. We thus expect to observe improved employment outcomes already before the acquisition of citizenship. We use micro-level register data from Statistics Netherlands from 1999 until 2011 (N?=?94,320) to test this expectation. Results show a one-time boost in the probability of having employment after naturalisation, consistent with the prevalent notion of positive signalling. However, we find that the employment probability of naturalising migrants already develops faster during the years leading up to citizenship acquisition, even when controlling for endogeneity of naturalisation. We conclude that it is not just the positive signal of citizenship that improves employment opportunities, but also migrants’ human capital investment in anticipation of naturalisation.  相似文献

When evaluating the smiles of other people (regarding amusement, authenticity, spontaneity, or intensity), perceivers typically rely on Orbicularis oculi activity that causes wrinkles around a target’s eyes. But does this so-called Duchenne marker also impact more generalized judgments of person characteristics (e.g., regarding a target’s attractiveness, intelligence, dominance, and trustworthiness)? To address this issue, the current study asked participants to provide the above smile evaluations and person judgments for a series of Duchenne and non-Duchenne smiles. The results showed that smile evaluations uniformly increased during Duchenne marker presence. The marker’s effect on person judgments, in contrast, was judgment dependent. While attractiveness, dominance and intelligence ratings showed the expected enhancement, trustworthiness ratings remained unaffected by the facial cue of interest. The findings suggest that the Duchenne marker’s role as a cue of social relevance during target perception depends on the type of person inference under consideration.  相似文献

Due to the highly variable concentration of sex hormone binding globulin (SHBG) and the many factors affecting it, the evaluation of the androgen status may require the measurement of a parameter of bioactive plasma testosterone. As, however, no practical, clinical useful direct method for measurement of plasma androgen bioactivity is available, indirect biochemical parameters are used. All have their limitations and pitfalls. In this paper are discussed some of the factors influencing the values obtained with different methods (direct measurement of free testosterone by analog radioimmunoassay, dialysis, ammonium sulfate precipitation, free testosterone index, calculated free and bioavailable testosterone), all of which may explain the variability of data reported in the literature. It is concluded that, whereas determination of bioavailable testosterone by dialysis or ammonium sulfate precipitation of SHBG-bound testosterone is work-intensive and not really suitable for clinical routine, while direct measurement of free testosterone by analog immunoassay yields unreliable results, only the free testosterone index and calculated bioavailable testosterone are adapted for clinical routine. The limitations of the free testosterone index, a dimensionless parameter which does not reflect a defined bioavailable testosterone concentration, are discussed. As the same measurements of testosterone and SHBG required for determination of the free testosterone index permit the calculation of bioavailable testosterone, which yields a defined androgen concentration, it is advisable to prefer the latter over the free testosterone index, which should no longer be used.  相似文献

The social sciences have achieved highly sophisticated methods for data collection and analysis, leading to increased control and tractability of scientific results. Meanwhile, methods for systematizing these results, as well as new ideas and hypotheses, into sociological theories have seen little progress, leaving most sociological arguments ambiguous and difficult to handle, and impairing cumulative theory development. Sociological theory, containing many valuable ideas and insights, deserves better than this. As a way out of the doldrums, this paper presents a systematic approach to computer–supported logical formalization, that is widely applicable to sociological theory and other declarative discourse. By increasing rigor and precision of sociological arguments, they become better accessible to critical investigation, thereby raising scientific debate to a new level. The merits of this approach are demonstrated by applying it to an actual fragment from the sociological literature.  相似文献

In a rank-order choice-based conjoint experiment, the respondent is asked to rank a number of alternatives of a number of choice sets. In this paper, we study the efficiency of those experiments and propose a D-optimality criterion for rank-order experiments to find designs yielding the most precise parameter estimators. For that purpose, an expression of the Fisher information matrix for the rank-ordered conditional logit model is derived which clearly shows how much additional information is provided by each extra ranking step. A simulation study shows that, besides the Bayesian D-optimal ranking design, the Bayesian D-optimal choice design is also an appropriate design for this type of experiments. Finally, it is shown that considerable improvements in estimation and prediction accuracy are obtained by including extra ranking steps in an experiment.  相似文献
