Opinion Taking within Friendship Networks 总被引:2,自引:0,他引:2
Suzanne L. Parker Glenn R. Parker James A. McCann 《American journal of political science》2008,52(2):412-420
Communication within friendship networks can provide gains in efficiency that help individuals enrich their understanding of politics. Through two panel survey experiments, we demonstrate that the dissemination of an individual's opinion about the hazards posed by public policies can have both durable and significant effects on the policy judgments of friends. These effects are conditioned by both the content of the communication and the recipient's level of political awareness. Opinions emphasizing potential risks carry more weight than those that attempt to alleviate concerns about potential risks. Moreover, opinion transmission is more effective for subjects who are less politically aware when policy issues are salient; but when the political issue is more esoteric, friends who are more politically aware evidence greater opinion change. 相似文献

We investigate the political economy of IMF forecasts with data for 157 countries (1999–2005). Generally, we find evidence of forecast bias in growth and inflation. Specifically, we find that countries voting with the United States in the UN General Assembly receive lower inflation forecasts as domestic elections approach. Countries with large loans outstanding from the IMF also receive lower inflation forecasts, suggesting that the IMF engages in “defensive forecasting.” Finally, countries with fixed exchange rate regimes receive lower inflation forecasts, suggesting the IMF desires to preserve stability as inflation can have detrimental effects under such an exchange rate regime. 相似文献

What type of oversight should states exercise over local units in order to prevent fiscal crises? This article discusses a sequence of three best practices that some states use to prevent fiscal emergencies. They first monitor local government finances to predict fiscal distress. After detecting signs of fiscal distress, states actively assist local units in ameliorating the problem. Finally, assistance notwithstanding, if a situation becomes grave, states require local units to take strong remedial measures, including increasing taxes and reducing expenditures. 相似文献

The forces associated with economic globalisation and the apparent supremacy of market forces have unleashed a range of political and social processes that have served, and were indeed designed, to enrich and empower the few at the expense of the majority. These include phenomena such as the rise in armed conflict, threats to food security, the loss of livelihoods and traditional ways of life of millions of people worldwide, the commodification of social provision, assaults on national sovereignty, and the privatisation of citizenship. However, the author argues, the most significant impact of globalisation is the 'localisation' of social and political struggle, and the emergence of new forms of international solidarity. Many NGOs have too readily succumbed to the view that globalisation in its present form is inevitable and irreversible, and have accommodated to it by trading their essential values for technical professionalism, often imported from the private sector. However, if NGOs are to assume their place as part of a transformational movement for social justice, they must rediscover and foster the values of citizen participation and develop a genuine respect for diversity. 相似文献

Detection of diatoms in blood by a combination of membrane filtering and chemical digestion 总被引:2,自引:0,他引:2
An improved method for detecting diatom in blood is reported. Blood of cadavers was obtained by cardiac puncture at inquest or from the left atrium directly at autopsy. The blood was hemolyzed by sodium dodecyl sulfate (SDS) and filtered through membrane filter (47 mm in diameter and 5 microns in pore size). When the blood was putrefied, two or three pieces of membranes filters were needed because of choking membrane pore. The membrane filters were digested with fuming nitric acid and diluted with distilled water. The diluted solution was filtered through membrane filter (25 mm in diameter) again. After drying the membrane filter was immersed in oil. Diatoms on the membrane filter were clearly observed microscopically. 相似文献

Studies are reported on microbial conversion of various unsaturated fatty acids to 10-hydroxy and/or 10-oxo fatty acids by Micrococcus luteus. Four fatty acids possessing cis-9-unsaturation produced 10-hydroxy and 10-oxo fatty acid products, but three enoic acids possessing trans-9-unsaturation or double bond(s) in other than the 9-carbon position were inactive as substrates. 10-Hydroxy palmitic and stearic acids were converted to the corresponding 10-oxo fatty acids, but the 10-oxo compounds were inactive as substrates. This indicates that the metabolic sequence of cis-9-enoic fatty acid by the microbial enzyme(s) is first converted to 10-hydroxy fatty acid and then to its 10-oxo compound. 相似文献

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners. 相似文献

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures. 相似文献

Scholars have recently debated whether non-recognition is a blessing or a curse for democracy. Some suggest that lack of recognition forces political elites to democratize and acquire internal legitimacy to compensate for the lack of external legitimacy. Others suggest that democratization is used as a strategy by which to acquire international recognition. Still others claim that non-recognition obliges unrecognized states to rely on a patron state which, in turn, hinders the quality of democracy. To contribute to this discussion, we have conducted an in-depth case study. Focusing on democratic quality in Northern Cyprus from 2010 to 2016, it is observed that reliance on a patron state leads to dynamics of tutelage, in turn hindering the quality of democracy. 相似文献
