Under what conditions can political elites influence elections to favor their preferred policy outcomes by strategically crafting the language printed on the ballot? Drawing on psychological and political theories of voter cognition, we design a survey experiment to assess the degree to which ballot text can influence voter behavior in direct democracy elections and identify factors that may moderate such effects. We show that the language used to describe a ballot measure does indeed have the potential to affect election outcomes, including measures dealing with contentious social issues affecting individual rights. We also find, however, that exposing individuals to basic campaign information—in our case, endorsements from prominent interest groups—greatly attenuates the framing effects of ballot text. Our results suggest that the extent to which ballot text matters depends on the vibrancy of the campaign environment and other information available to voters.  相似文献

Since the Korean criminal DNA database was launched in 2010, we have focused on establishing an automated DNA database profiling system that analyzes short tandem repeat loci in a high‐throughput and cost‐effective manner. We established a DNA database profiling system without DNA purification using a direct PCR buffer system. The quality of direct PCR procedures was compared with that of conventional PCR system under their respective optimized conditions. The results revealed not only perfect concordance but also an excellent PCR success rate, good electropherogram quality, and an optimal intra/inter‐loci peak height ratio. In particular, the proportion of DNA extraction required due to direct PCR failure could be minimized to <3%. In conclusion, the newly developed direct PCR system can be adopted for automated DNA database profiling systems to replace or supplement conventional PCR system in a time‐ and cost‐saving manner.  相似文献

The operation of a motor vehicle requires the integrity of sensory, motor, and intellectual faculties. Impairment of these faculties following the consumption of alcohol has been studied extensively through laboratory, closed‐course and on‐road driving, and epidemiological studies. The scientific literature was reviewed critically, with a focus on low‐to‐moderate blood alcohol concentrations (BAC ≤ 0.100%), to identify the most reliable determinants of alcohol‐impaired driving. Variables such as age, gender, driving skill, and tolerance were shown to have limited impact on impairment. It was concluded the most relevant variables are BAC and complexity of the driving task. The scientific literature provides a high degree of confidence to support the conclusion that a BAC of 0.050% impairs faculties required in the operation of a motor vehicle. Whether impairment is apparent depends upon the complexity of the driving task, which applies to both study design and actual driving.  相似文献

The use of a direct analysis in real time (DART) mass spectrometer (MS) instrument was optimized for 22 compounds of organic explosive residues to provide a guide for DART‐MS users in rapid screening of explosive compounds. Samples were introduced as neat solutions and sequential dilutions to determine optimal instrument conditions and lowest concentration detectable. Most compounds were optimized to 250°C in the negative ion mode, and several compounds benefited from the addition of a chloride dopant from methylene chloride (amino‐dinitrotoluenes, RDX, EGDN, and PETN). Few compounds were more sensitive in the positive ion mode (TEGDN, DEGDN, HNS, and DMNB). Mixtures of compounds were detected using clean room wipes, directly from their surfaces and from subsequent extractions. Compounds from the mixtures were also successfully detected in soil and from swipes of spiked surfaces. The instrument showed merit in detection of pg/μL solutions for most of the compounds and among the substrates tested.  相似文献

Typically, safety‐related driver education programs are aimed at changing knowledge of vehicle operation rules and regulations. However, vehicle crashes are as likely to be related to driver personality variables as they are to the knowledge of vehicle operation and rules and regulations. In a study with 48 licensed drivers, crashes were found to be significantly correlated with conscientiousness, a five‐factor model personality dimension, but not with scores on a driving knowledge test. It would appear that prevention efforts should also be directed at changing conscientiousness‐related behaviors, including an emphasis on goal‐setting, and following rules and regulations.  相似文献

International diplomacy, to the extent it is effective, should not only prevent escalation of low‐intensity conflict, but should also facilitate de‐escalation. This article focuses on the short‐term effects of managing low‐intensity civil wars through third‐party mediation. Specifically, we compare the efficacy of third party‐mediated direct (face‐to‐face) and indirect talks in low‐intensity civil wars from 1993 to 2004 using the Managing Intrastate Low‐Intensity Conflict data set. We argue that a focus on short‐term success is valid because of the relationship among mediation, short‐term success, humanitarian aid access, and peacebuilding. We also assess the roles of mediator identity, mediation strategy (behavior focus versus incompatibility focus), peace agreements, war type, per capita gross domestic product, level of democracy, and conflict duration. Our overarching finding is that direct forms of mediation in which all parties meet face to face were the most likely to yield short‐term success in the sample of civil wars that we analyzed.  相似文献

机动车能否安全行驶,在一定程度上取决于机动车驾驶人掌握行驶安全距离的能力。机动车行驶安全距离是指从发现障碍开始制动,到最后完全停止所行驶的距离,它包含纵向行驶安全距离和横向行驶安全间距。纵向行驶安全距离取决于制动停车距离;横向行驶安全距离应根据路面的不同、气候的变化灵活掌握。由此可见,机动车驾驶人必须根据机动车的行驶速度、道路状况、气候条件、装载状况等因素,灵活掌握机动车的行驶安全距离,以充分保证其行驶的安全性。  相似文献

法治理念是依法治国的观念基础,公安执法是实现依法治国的重要途径。基于共同的价值追求,两者在对法律、权力、权利和程序的认知方面具有高度一致性,因而具有同构关系。从理论上论证两者之间的同构关系,分析其交互功能价值,对未来我国法治建设和公安执法规范化建设具有理论指导意义。  相似文献
