This study's goal was to establish the prevalence of driving under the influence of alcohol (DUI) and alcohol consumption patterns among drivers in Cali, Colombia, in 2013. A cross-sectional study based on a roadside survey using a stratified and multi-stage sampling design was developed. Thirty-two sites were chosen randomly for the selection of drivers who were then tested for blood alcohol concentration (BAC) and asked to participate in the survey. The prevalence of DUI was 0.88% (95% confidence intervals [95% CI] 0.26%–1.49%) with a lower prevalence when BAC was increasing. In addition, a higher prevalence was found during non-typical checkpoint hours (1.28, 95% CI ?0.001%–0.03%). The overall prevalence is considered high, given the low alcohol consumption and vehicles per capita. Prevention measures are needed to reduce DUI during non-typical checkpoints and ongoing studies are required to monitor the trends and enable the assessment of interventions. 相似文献

To clarify the relation between the curriculum system and the understanding of nutrition terms, 944 students aged 8–12 years living in Japan, the USA and the UK, were asked about the recognition, medium for recognition, and understanding of nutrition terms. The effect of nutrition education from an early stage in elementary schools in the UK and the USA was confirmed. These results suggest the possibility of beginning nutrition education earlier in the elementary school in Japan. American students had paid attention to food labels. These results showed that a learning and teaching strategy founded on comprehensively based subjects in the USA had influenced good behaviour for dietary life. On the other hand, there was not a relationship between an understanding of nutrition terms and a developmental stage. Many students in three countries were influenced by television commercials to buy candy or soda. We think that it is important to develop a curriculum that includes practical learning and ensures hours of teaching for the purpose of acquirement of nutritional knowledge. It is also necessary to encourage critical thinking skills to evaluate television commercial messages through school lessons. 相似文献

Homelessness in South Africa requires collaborative research. Social, political, cultural and economic factors that cause homelessness must be considered to develop a common definition and understanding of homelessness. South Africa’s social complexity and diversity make it challenging to construct available results into one conceptual framework, and this in turn complicates national policy implementation and role allocation. By means of a rapid critical appraisal of literature on homelessness in South Africa, researchers provide evidence to direct and structure contextual research pertaining to homelessness. Four themes transpire: conceptualisation; demography; roles and responsibilities of key stakeholders; and strategic policy and research issues. Researchers caution that the findings are not generalisable, because of the rapid nature of the appraisal and possible selection bias of the literature. Measures of validity were used to ensure that the study accomplished its purpose through the key results and to ensure that the results are a true reflection of available evidence. 相似文献

Until the Rio Flood Reconstruction and Prevention Project, disaster-related projects funded by the World Bank focused primarily on reconstruction, especially immediate, short-term recovery. The Rio de Janeiro project was notable as a targeted effort to reduce disaster vulnerability by promoting long-term multisectoral development strategies. It taught that reconstruction projects must address specific disaster vulnerabilities as well as cross-sectoral needs in Improving urban environmental management. The project represents a significant step towards developing a strategy for long-term prevention and mitigation of natural disasters and environmental degradation. It is also a good example of an effort to develop support for long-term environmental policies by strengthening indigenous managerial and planning capabilities—something that was not possible in short-term recovery projects. 相似文献

This article derives from a project which has developed a major reconceptualization and revision of how borders may be seen and measured through the use of GIS. This reconceptualization permits an investigation of the specific qualities of borders in terms of opportunity and willingness: ease of interaction and salience, respectively. Data generated by the GIS reconceptualization ‐ both maps and numerical measures ‐ are used to look at the nature of the contiguous borders that link enduring rivalry dyads, with a specific focus on Israeli borders. Even as a first‐cut, the GIS‐based reconceptualization is demonstrated to be of use by highlighting areas of opportunity and/or salience and informing policy choices. 相似文献

Group Support Systems may be “distributed”; for nonsimultaneous use by being embedded in a Computer‐Mediated Communication System (CMCS). In this manner, large groups may use them for complex tasks over an extended period of time. Will executives use such systems, and what are their reactions? This case study of elites engaged in formulating recommendations for the White House Conference on Productivity demonstrates that executives can use such systems, given that “critical success factors”; are met. Perceived information richness is strongly correlated with perceptions of productivity enhancement as a result of system use. 相似文献

Because AIDS affects primarily the most productive age groupand is fatal and widespread, it will have a larger impact onAfrican development than other more common diseases. Infectionrates are higher in urban than in rural areas, and studies suggestthat they are highest among urban high-income, skilled men andtheir partners. Macroeconomic models show that the greater theinfection rate among educated workers and the greater the propensityto finance medical care out of savings, the more detrimentalis the impact of AIDS on the growth of per capita income. Regardlessof the macroeconomic effect, most households and businessesdirectly affected by AIDS will be economically worse off, atleast in the short run. It is not clear, however, what effectAIDS will have on poverty in Sub-Saharan Africa or on incomeinequality. Governments need to assess the potential economicimpact of AIDS, implement cost-effective programs to mitigatethe impact, and target prevention programs to the economic sectorsmost sensitive to HIV infection. 相似文献

A good ‘market’ for health futures and easy access to relevant information are among the reasons that health futures is currently centred in the wealthy nations. Interest in health futures is growing in the less developed countries, however, in part because of efforts by WHO and its regional office. Many benefits can be expected if the field becomes more international, including an influx of fresh ideas about health futures study designs and about innovative approaches to health care. A shift to a more global orientation is also imperative simply because health futures deals with the well-being of human beings, and most human beings live in the less developed countries of the world. 相似文献

Impacts of Asynchronous Learning Networks on Individual and Group Problem Solving: A Field Experiment 总被引:1,自引:1,他引:0
An Asynchronous Learning Network (ALN) is a Computer-Mediated Communication System designed to support "anytime/anywhere" interaction among students and between students and instructors. A field experiment compared groups and individuals solving an ethical case scenario, with and without an ALN, to determine the separate and joint effects of communication medium and teamwork. Dependent variables include quality and length of the reports, and subjective perceptions of learning and satisfaction. The results indicate that that an ALN enhances the quantity and quality of the solutions to an ethical case scenario. The combination of teamwork with ALN-support increases the students' perception of learning. Although the perception of collaborative learning was similar between ALN-supported and unsupported groups, participants in computer-mediated groups reported lower perceptions of discussion quality than participants in manual groups. 相似文献
