Voting has been described as a contribution to a public good. Are people who vote frequently therefore more likely to contribute to other public goods? Does partisanship affect how likely a person is to engage in these cooperative behaviors? Although surveys suggest that the answer to these questions is “Yes,” few empirical studies examine these questions using observed behaviors. We examine them in the context of a large‐scale, randomized controlled trial to induce voluntary action in a common‐pool resource dilemma. During a drought in the southeastern United States, pro‐social messages that encouraged water conservation were randomly assigned to 35,000 out of 106,000 households. Frequent voters in primary and general elections (1990–2008) were substantially more responsive to the messages, but there was no detectable difference in the responses of Republican and Democrat households. Our results suggest that internalized pro‐social preferences promote action for the public good across behavioral contexts. 相似文献

This article explores three NGO projects that assemble and distribute clean birthing kits in Ethiopia. It contrasts the government's health strategy that aims to increase skilled birth attendance, with local realities as most women in rural and remote settings give birth at home, often in unhygienic conditions, and without skilled assistance. Many health facilities are also unable to provide hygienic conditions for birthing women. The findings indicate that clean birth kits have assisted the NGOs to effectively promote clean delivery at home or in health facilities, and to encourage antenatal care, and early referral to emergency obstetric and new-born care. 相似文献

The Forensic Science Service (FSS) has devoted appreciable effort to developing the application of the principles of evidence interpretation. Much of the work has been reported in previous papers in this journal, in particular those that develop a model for Case Assessment and Interpretation (CAI). The principles of interpretation are restated and the implications for structure and content of statements are described. 相似文献

Five marijuana samples were compared using bulk isotope analysis compound-specific isotope ratio analysis of the extracted cannabinoids. Owing to the age of our cannabis samples, four of the five samples were compared using the isotope ratios of cannabinol (CBN), a stable degradation product of Δ(9)-tetrahydrocannabinol (THC). Bulk δ(13)C isotope analysis discriminated between all five samples at the 95% confidence level. Compound-specific δ(13)C isotope analysis could not distinguish between one pair of the five samples at the 95% confidence level. All the measured cannabinoids showed significant depletion in (13)C relative to bulk isotope values; the isotope ratios for THC, CBN, and cannabidiol were on average 1.6‰, 1.7‰, and 2.2‰ more negative than the bulk values, respectively. A more detailed investigation needs to be conducted to assess the degree fractionation between the different cannabinoids, especially after aging. 相似文献

Four males ingested one cup of Health Inca Tea which contained 1.87 mg of cocaine. Urine specimens collected for 36 h post-ingestion were analyzed for benzoylecgonine (BE) by EMIT-d.a.u., TDx and gas chromatography/mass spectrometry (GC/MS). Positive immunoassay results were obtained for 21-26 h post tea ingestion. Discrepant immunoassay results occurred with only one specimen: EMIT positive; TDx negative, 0.25 mg/l; GC/MS, 0.273 mg/l. Quantitative TDx results were well correlated with GC/MS results, r2 = 0.963, n = 45. Maximum urinary BE concentrations ranged from 1.4-2.8 mg/l, occurring from 4-11 h, post ingestion. Total BE excretion in 36 h ranged from 1.05 to 1.45 mg, 59-90% of the ingested cocaine dose. Urinary excretion rate constant (Km) ranged from -0.073 to 0.111/h. Health Inca Tea ingestion should be considered when interpreting urinary BE concentrations. 相似文献
