When studying sensitive issues, including corruption, prejudice, and sexual behavior, researchers have increasingly relied upon indirect questioning techniques to mitigate such known problems of direct survey questions as underreporting and nonresponse. However, there have been surprisingly few empirical validation studies of these indirect techniques because the information required to verify the resulting estimates is often difficult to access. This article reports findings from the first comprehensive validation study of indirect methods. We estimate whether people voted for an anti‐abortion referendum held during the 2011 Mississippi General Election using direct questioning and three popular indirect methods: list experiment, endorsement experiment, and randomized response. We then validate these estimates against the official election outcome. While direct questioning leads to significant underestimation of sensitive votes against the referendum, indirect survey techniques yield estimates much closer to the actual vote count, with endorsement experiment and randomized response yielding the least bias. 相似文献

Those who turn out in American primary elections are a small and unrepresentative subset of the population. Why do citizens forgo participation in nominating contests yet vote in general elections? We argue that limited contact lowers participation in primary elections. We present results from a randomized field experiment with near 150,000 letters in California’s 2014 primary. Each letter went to one of the four million Californians who had participated in recent general elections but not in primaries. We find that a single letter increased turnout by 0.5 points from a base rate of 9.3 percent. This increase is more than twice the average effect calculated in a recent meta-analysis and represents a proportional increase of 5.4 percent. Our experiment shows that registrants who typically abstain from primaries—and who are thus often ignored by campaigns—can be effectively mobilized. 相似文献

Elemental Characterization and Discrimination of Nontoxic Ammunition Using Scanning Electron Microscopy with Energy Dispersive X‐Ray Analysis and Principal Components Analysis 下载免费PDF全文

Concerns over the toxic by‐products produced by traditional ammunition have led to an increase in popularity of nontoxic ammunition. In this work, the chemical composition of six brands of nontoxic ammunition was investigated and compared to that of a road flare, which served as an environmental source with similar composition. Five rounds of each brand were fired while a further five were disassembled and the primer alone was fired. Particles collected from all samples, including the road flare, were analyzed by scanning electron microscopy with energy dispersive X‐ray analysis. Common elements among the different ammunition brands included aluminum, potassium, silicon, calcium, and strontium. Spectra were then subjected to principal components analysis in which association of the primer to the intact ammunition sample was generally possible, with distinction among brands and from the road flare sample. Further, PCA loadings plots indicated the elements responsible for the association and discrimination observed. 相似文献

Recent work on the ethics of war has struggled to simultaneously justify two central tenets of international law: the Permission to kill enemy combatants, and the Prohibition on targeting enemy noncombatants. Recently, just war theorists have turned to collectivist considerations as a way out of this problem. In this paper, I reject the argument that all and only unjust combatants are liable to be killed in virtue of their complicity in the wrongful war fought by their side, and that noncombatants are not permissible targets because they are not complicit. I then argue that just combatants have some reason to direct force against unjust combatants rather than unjust noncombatants, because they should respect the reasonable self-determining decisions of other political communities, when those communities settle on the distribution of a negative surplus of cost for which they are collectively but not individually responsible. These collectivist reasons will not fully justify the Permission and the Prohibition, but they can contribute to that justification. 相似文献

How do public administrators understand social equity toward lesbian, gay, and bisexual (LGB) individuals and communities? To better understand social equity, this study uses data on the views of public and nonprofit administrators in 33 countries in Africa on LGB people. Based on these responses, we gain a better understanding of homophobia in public administrators. Furthermore, this data helps public administrators to explore how social equity might look differently to public and nonprofit administrators in different countries. Building on this foundation, this study proposes understanding social equity from both a Micro (individual) and a Macro (cultural)-perspective. Bringing in this micro- and macro-perspective can help public administrators and researchers to discuss how individuals and organizations identify “vulnerable” populations and appropriate ways to support vulnerable groups. 相似文献

Citizens and victims perceive the criminal justice system to be protracted. Blame for lengthy delays has disproportionately fallen on detective work. To that end, these analyses explore how long it took 184 detectives to work index crimes. Data suggest that more serious crimes, cases with a known suspect, and offenses that did not result in an arrest are most likely to be investigated and worked more promptly by detectives. Detectives, however, continue to exercise a great deal of discretion in if and when cases are worked once they are assigned. These findings are discussed as they relate to police performance indicators, the allocation of departmental resources, issues of crime control, and citizen satisfaction with the police. 相似文献

We explore three trends in rural southern Mexico (Fair Trade coffee, migration, and conditional cash transfers) that could explain the rapid rise in education from 1995–2005 using survey data from 845 coffee farming households in Oaxaca and Chiapas, Mexico. Results from a household fixed-effects model show that household participation in a Fair Trade-organic cooperative contributed to about a 0.7 year increase in schooling for girls. US migration opportunities appear to have even stronger positive impacts on schooling for females. Although participation in Fair Trade-organic cooperatives appears also to have increased male schooling, increased migration opportunities have had an indeterminate effect for males. 相似文献

The article explains the features and evolution of the Central Provident Fund (CPF) scheme in Singapore and the reforms it has undergone in the face of recent challenges. At its inception, it was designed as an exclusively state managed savings scheme to meet the retirement needs of its members. Over the years, it has been gradually liberalised, allowing account holders to use their savings for additional purposes. In recent years two key challenges have arisen. One has been the problems arising out of liberalisation itself, which has left too many CPF members with insufficient savings for their retirement as a result of mistaken or imprudent choices in committing their savings to the additional options available. In response, the Singapore government has tempered or reversed the process of liberalisation, imposing or maintaining constraints on the use of CPF savings so as to ensure sufficient savings to meet retirement needs. The second challenge is the need to restructure the Singapore economy in the face of regional and global competition so as to sustain the profitability of the business sector and enhance employability of the older workers. The response of the government has been to allow the CPF contribution rates of employers to be adjusted and the CPF salary ceiling to be lowered so as to reduce business costs and increase the chances of employment of older workers. However, using the CPF scheme as a macroeconomic tool by reducing employers’ contribution rates may lead to less scope for CPF members to accumulate sufficient savings for their retirement. This would mean that the response to the second challenge would be at odds with the response to the first challenge. 相似文献

The present article outlines the role of personal, social, and cultural identity in religiously and ethnically motivated terrorism. It is proposed that terrorism represents the confluence of a cultural identity strongly based in collectivism and in fundamentalist adherence to religious or cultural principles, a social identity based in sharp contrasts between one's own group and groups perceived as threats, and a foreclosed and authoritarian sense of personal identity or, less often, a diffused and aimless personal identity. Examples from religious-extremist and ethnic conflicts in which terrorism has been employed are used to illustrate the tenets advanced here. Recommendations for addressing and preventing the threat of terrorism are discussed. 相似文献
