This study aimed at investigating the predictors of hard drug dealing crimes among Mexican students. Tests of difference and
ordinal regression were employed to explore group differences and predictors of hard drug dealing crimes. The sample included
14,306 last-year high school students nationwide. Results show that 3.5% of the students surveyed admittedly reported to have
been involved in a drug dealing crime of an illegal substance different from Marijuana. Several factors were found to decrease
the odds of a student to get involved in a hard drug crime. Federal policy implications and solutions are provided. 相似文献

This article explores the ways in which the immigration of Nicaraguans to Costa Rica is represented by Costa Rican institutions and individuals through public discourses and everyday life. Three discourses are considered. First, intellectual claims that immigration poses a threat to Costa Rican national identity, whereby intellectuals portray 'Costa Rica in crisis' due to immigration. Second, fictional works seek to represent issues regarding the Nicaraguan community in innovative ways, being open‐ended and including diverse voices. Third, stories written by Nicaraguan children are discussed in view of exploring how hostility towards immigration interpellates them, who face the challenge of negotiating their identities with their peers in everyday life. The article ends by asking for a politics able to defend public institutions and public investment, able to forge networks of solidarity with immigrant communities. 相似文献

This article analyses the job satisfaction of primary school teachers in Madagascar. Based on the estimation of multilevel models, low wages and problems getting paid, job insecurity, lack of in-service training, high pupil-teacher ratios, and lack of basic infrastructure and teaching materials are identified as the main reasons for dissatisfaction. Principals’ control of teachers’ activities also adversely affects satisfaction, suggesting that, in Malagasy schools, neither school directors nor teachers have succeeded in adopting organisational cultures based on cooperation among their members. These results are likely to stimulate debates on educational policy, both in Madagascar and in many other developing countries. 相似文献

This exploratory study examines the ethical ideologies of a sample of 76 juvenile court judges attending a conference using an Ethical Position Questionnaire. Potential effects of ethical orientation on judicial decision making are identified and discussed. The findings indicate a relatively even distribution of judges across ethical ideologies. The connection between ethical ideology and the prevailing juvenile justice philosophy across jurisdictions, and the importance and complexity of judicial education and training in juvenile justice, are discussed. 相似文献

Cyanoacrylate fuming is one of the most common techniques employed for the detection of latent fingermarks on non-porous surfaces such as plastic and glass. The technique is generally applied by exposing items of interest to the vapours generated by heating a suitable quantity of commercial cyanoacrylate adhesive. In this study, the potential for highly toxic hydrogen cyanide (HCN) to be generated from the overheating of cyanoacrylate was investigated. Two commercial cyanoacrylate adhesives and two quantitative methods for the determination of HCN were employed: (i) the sodium picrate method; and (ii) the picrate-resorcinol method. (13)C nuclear magnetic resonance (NMR) analysis was used to confirm the presence of cyanide. In addition, the thermal decomposition of cyanoacrylate was studied using simultaneous thermogravimetric and differential thermal analysis (TGA-DTA). It was determined that detectable and quantifiable amounts of HCN were generated from the thermal decomposition of cyanoacrylate monomer and polymer at temperatures as low as 200 °C. Using an optimised picrate-resorcinol method, it was shown that around 10 μg of HCN could be generated from the heating of 1g of cyanoacrylate monomer at 200 °C. For one of the adhesives tested, this increased to above 100 μg of HCN when 1g of cyanoacrylate monomer was heated at 280 °C. Recommendations are provided that, if followed, should ensure that the cyanoacrylate fuming process can be safely applied with minimal risk to the operator. 相似文献

In some Latin American nations, policy change occurs frequently, while in others it is stable, less prone to shifts with the prevailing political climate or shocks. The conditions under which institutional rules and the powers of key actors influence the capacity for governance vary, and this variation is seldom addressed in the literature. This project examines the effects of the interactions between key policymakers (the executive and the legislature) in Latin America on policy stability across different institutional frameworks. Countries with simultaneously strong executives and weak legislatures are shown to have unstable policy environments, as are countries with a history of unified government and, to a lesser extent, candidate‐centered electoral systems. 相似文献
