While studies have shown that adults use smoking to deal with stress, little research has been carried out with children to explore their perceptions of smoking as a coping strategy. Qualitative questionnaire and interview data were generated with children aged 9–11 years. Participants perceived that adults smoked to relieve boredom and stress, and suggested that children might smoke for the same reasons. Children were more likely to know that adults smoked to deal with stress if they lived in a deprived area. Girls were more likely to believe that some children need to smoke as a coping strategy.  相似文献

Latinos tend to have significantly lower levels of access to general and top quality medical care than do non-Latino whites, and although disparities in access to health care have diminished for all other minority groups over time, they have widened for Latinos. Given these trends, current attempts to provide universal health care at both the national and state levels across the United States have large implications for the health status of Latinos. The objective of this analysis is to determine whether Latinos have different attitudes regarding health reform than non-Latino whites. Our data are from a statewide random digit dialing telephone survey of New Mexico residents, age 18 and older, conducted in the Fall of 2007. With a Latino population of 44% and ongoing health care reform efforts by the state legislature, New Mexico is an ideal location for this analysis. After controlling for a host of individual level factors, our findings suggest that while Latinos are less likely to identify health care as a salient state issue relative to the economy and crime, they are more likely than non-Latino whites to believe affordable health care programs are important. Finally, Latinos view employers, more than government or individuals, to be responsible for expanding health care coverage.  相似文献

Objective. This article explores the empirical effects of U.S. drug policy on coca cultivation in the Central Andes. We assess the impact of U.S. military assistance on the production of coca in the Central Andes, while controlling for other explanatory variables that influence coca cultivation. Method. Using data from 1980–2001 for Colombia, Bolivia, and Peru, we perform a pooled cross‐sectional time‐series analysis. Results. The effects of U.S. military assistance on coca cultivation are not uniform across the Central Andes. Coca production decreased in Bolivia and Peru and increased in Colombia. Total coca production in the Central Andes, however, remained unchanged. Conclusion. This study is consistent with existing literature that points out the obstacles governments face as they attempt to suppress illicit goods. Specifically, our empirical findings support the idea of the “balloon effect,” whereby government efforts to “squeeze” illicit trade in one area result in the expansion of that trade elsewhere.  相似文献

Seeking common ground for people: Livelihoods, governance and waste   总被引:2,自引:1,他引:1  
Jam Chakro is a large International Donor-funded landfill site in Karachi, when opened in 1996 it was intended to be carefully managed by the Karachi municipal authorities. However, within weeks of opening it was overtaken by informal-sector waste workers. They are mostly poor rural migrants who have gravitated towards urban areas seeking work. Their waste sorting and recycling work, which involves burning waste, is now responsible for serious environmental degradation and poor waste management.Nearby residents are being affected by the smoke, and wish to see an end to the burning. Local authorities are under pressure to manage the waste better and wish to see an end to the recycling activities. However, initial attempts to stop these activities and relocate people, sometimes involving force, have been unsuccessful. The workers complain that they depend on the waste work for their survival.This paper is concerned with the problems caused by the informal-sector recycling work at Jam Chakro, and the need for finding environmentally and financially sustainable solutions which respect the interests of all stakeholders. It is based on fieldwork which involved detailed stakeholder identification and consultation, to ensure that different perspectives were heard and accounted for. In the light of research findings, the paper discusses some of the proposed options for integrating informal-sector livelihoods into the formal operation of the landfill site. These are based around organising waste reclamation and recycling work and enabling it to take place without burning waste.The paper proposes that the problems at Jam Chakro can in part be attributed to not having accounted for the poor in planning, necessary for developing sustainable solutions to the problems.Approximate exchange-rate at time of writing: US$1: Rs. 60.  相似文献

The utilization of DNA evidence in cases of forensic identification has become widespread over the last few years. The strength of this evidence against an individual standing trial is typically presented in court in the form of a likelihood ratio (LR) or its reciprocal (the profile match probability). The value of this LR will vary according to the nature of the genetic relationship between the accused and other possible perpetrators of the crime in the population. This paper develops ideas and methods for analysing data and evaluating LRs when the evidence is based on short tandem repeat profiles, with special emphasis placed on a Bayesian approach. These are then applied in the context of a particular quadruplex profiling system used for routine case-work by the UK Forensic Science Service.  相似文献
