Scholars have consistently found that firms in developing countries adopt voluntary environmental programs (VEPs) in high numbers when their major trade partners are home to many VEP-certified firms. This reflects the following dynamic: Importers based in countries with many VEP-certified facilities demand similarly sustainable production processes from trade partners, and so exporting firms in partner countries adopt VEPs to signal their sustainable practices. Studies have identified characteristics of developing countries that make local exporting firms more likely to adopt VEPs as a signal; however, there has been little analysis as to the country-level characteristics that make importers more (or less) likely to demand VEPs from suppliers abroad, beyond having many VEP-certified firms themselves. This study considers this matter, theorizing that VEP diffusion only accompanies exporting to countries with high levels of income and education, as well as a high number of VEP-certified firms. Panel data analysis provides support for the theory, showing that developing countries only experience trade-based diffusion of ISO 14001 (a widely adopted VEP) through their exports to countries with high income and/or education levels. In contrast, exporting to countries that lack these characteristics creates no such diffusion, even where importing countries’ VEP certification levels are high. Instead, such trade produces a “stuck in the mud” effect, as developing countries’ certification levels stagnate even as those of their import partners rise.  相似文献

Declining levels of turnout are a problem in European elections. Are Get Out The Vote campaigns the solution to the problem? While many studies have investigated such campaigns in the US, little is known about their effect in Europe. The article presents a field experiment in which encouragement to vote in an upcoming Danish election is delivered to more than 60,000 first-time voters using direct personal letters. Eight different letters are designed, based on the calculus of voting and prospect theory. The sample is randomly divided into treatment groups or the control group. Using validated turnout, small positive effects of receiving a letter on turnout are found, with little difference across letters. The letters mostly mobilised voters with a low propensity to vote and thus increased equality in participation. In sum, while letters have some effect, they are not likely to be a panacea for solving Europe’s turnout challenges.  相似文献

Issue ownership, or the idea that some parties are considered by the public to be better able or more committed to dealing with specific issues, is increasingly used in studies of electoral choice. Yet, various scholars have argued that if measures of issue ownership are confounded with party choice, this raises concerns regarding their usability to predict electoral choice. This research note examines to what extent various measures of issue ownership are confounded with voters’ party preferences and voters’ agreement with the party's position on the issue. Relying on an online survey‐embedded question wording experiment fielded in two countries (Belgium and Denmark), question wording effects for two dimension of issue ownership are examined: competence issue ownership and associative issue ownership. It is found that, in both countries, the two associative issue ownership measures were less affected by party preference and positional agreement. The most used competence issue ownership measures are most confounded with party choice and positional agreement in the experiment. Results in the two countries are largely similar, the main exception being that one of the two associative measures performs worse in Denmark. The results imply that scholars should take care in using measures of especially competence issue ownership to predict the vote, but that also country differences affect the validity of issue ownership measures.  相似文献

Adverse childhood experiences (ACEs) have been identified as a key risk factor associated with a wide range of negative life outcomes, including juvenile delinquency. Much less work has explored whether certain combinations of ACEs, or typologies of trauma, exist, and whether or not these subgroups are differentially associated with certain youth-level and/or community-level characteristics. The current study uses latent class analysis to examine ACE typologies among a sample of over 92,000 juvenile offenders between the ages of 10 and 18 in the state of Florida (52% male, 37.3% White, 46.8% Black, 15.9% Hispanic). Multilevel multinomial logistic regression is used to assess the relationship between both individual- and community-level factors and class membership. The findings suggest that a total of five distinct ACE typologies exist among the sample of juvenile offenders, and age, race, and sex were significantly associated with class membership. Additionally, controlling for individual-level characteristics, community-level measures of immigrant concentration, residential instability, and two separate measures of concentrated disadvantage and affluence were significantly related to class membership. This study contributes to the understanding of adverse childhood experiences, and adds to existing knowledge regarding the relationship between contextual factors and childhood abuse, maltreatment, and trauma. The identification of ACE subgroups with distinct characteristics may help guide prevention strategies and tailor treatment provided by the juvenile justice system.  相似文献

In Virginia, major differences between revenue forecasts and actual revenue collections raised questions from legislators about the adequacy of the state's econometric forecasting models and the forecasting process itself. Consequently, Virginia's process and models were examined by the Joint Legislative Audit and Review Commission (JLARC), a legislative watchdog agency. The review found most of the differences could be attributed to declining economic factors and not poor forecasting. However, a surprisingly large component of the forecast was based on undocumented judgmental inputs that required greater oversight. Other states in similar circumstances may wish to evaluate their own forecasting process and econometric models using the JLARC approach.  相似文献

Responding effectively and efficiently to the needs of persons with mental illness returning to the community from prison requires identifying their differences in need and placement difficulties upon return and targeting reintegration investments to reflect these differences. This paper has three parts. The first part profiles the male special needs population in New Jersey prisons. These profiles describe behavioral health and criminal justice characteristics of 2715 male inmates with mental health problems, and are used to identify the scope and nature of the public's investment opportunity. The next part describes the costs associated with possible "investments." The special needs population is classified by need and placement difficulty, and then matched to reentry and community-based treatment programs. Costs are estimated for reentry planning and community-based treatment for the first year post-release. The third part recommends an investment strategy and a set of operational changes that might minimize the loss and maximize the return on the public's investment dollar in mental health.  相似文献
