Lipset and Rokkan??s (Party system and voter alignments: cross national perspectives, Lipset and Rokkan eds., New York: Free Press, pp. 1?C64, 1967) sociological model of cleavages and the so-called ??freezing hypothesis?? dominate theorizing about party system formation. Torcal and Mainwaring (Br. J. Polit. Sci. 33:55?C84, 2003) show the relevance of a purely political cleavage for structuring the party system in the case of Chile, challenging the freezing hypothesis??s claims. They also dispute case-specific research that argues Chile??s party system still reflects a ??three-thirds?? division between Left, Right, and Center. Revisiting this debate, our study employs spatial maps of the party system. Such political-economy models are rare in studies of Latin American politics. The application here supports a democratic/authoritarian political cleavage in Chile. 相似文献

We examine legislative shirking under conditions of imperfect constituent monitoring. Our core argument states that variation in information costs and constituent memory leads to systematic variation in constituent monitoring over time. Assuming that legislators are responsive to multiple cues, we expect to observe time-dependent legislative shirking. We develop a theoretical model of legislative behavior with time-dependent monitoring, which we test empirically using Senate roll call data. Our findings show that a substantial number of senators engage in systematic, time-dependent shirking, and that senators consistently move toward extreme positions when monitoring is low and toward moderate positions when it is high. 相似文献

Learning through social communication is promoted when citizens are able to identify which of their associates is likely to
possess the necessary political information. This paper examines the factors that influence individuals’ evaluations of political
expertise. Actual political expertise plays a large role in perceived expertise, but mistakes are made. These are largely
the result of assuming that those engaged in politics must also be knowledgeable about politics. This paper uses the 1996
Indianapolis-St. Louis Study and the 2000 National Election Study to identify factors that bias levels of perceived political
knowledge. The paper concludes by demonstrating that perceived expertise plays a larger role than actual expertise in the
social influence process. 相似文献

Five mechanisms have been described in the literature regarding lightning injury mechanisms. A sixth mechanism is proposed in this article, namely, lightning barotrauma. A simple laboratory experiment was conducted using ordnance gelatin for ballistic studies. Lightning was simulated in a high-voltage laboratory using an 8/20-microsecond current impulse generator and discharged through ballistic gel. Temporary and permanent cavity formations were confirmed. The cavities formed were directly proportional to the currents used. Findings suggest that a sixth mechanism of lightning injury, namely, barotrauma, should be considered. 相似文献

It is well established that geographic areas benefit, in terms of the share of government spending they capture, from having a legislator with longer tenure, holding constant the tenure of other legislators. However, the implications of this literature for how the total production of legislation changes if all members gained seniority is less clear. Increased levels and dispersion of seniority within Congress generate a cartel-like effect, whereby legislators restrict the quantity of legislation enacted and increase the average price of each passed bill. The analysis provides a natural experiment to gauge the impacts of the emergence of the congressional committee system. 相似文献

Although a plethora of studies focus on jury decision making in sexual harassment cases, few studies examine damage award assessments in such suits, and even fewer explore the impact of psychological injury on jurors’ liability and damage award assessments. In the present study, 342 undergraduates read a hostile environment sexual harassment case that manipulated the plaintiff’s psychological injury level (severe vs. mild vs. control) to investigate whether males and females made different damage decisions. Males using a reasonable person standard found more liability as the severity of the plaintiff’s psychological injury increased. However, males using a reasonable woman standard found less liability with the addition of any psychological injury information. Similarly, for mild and severe injuries, males using the reasonable woman standard awarded lower damages than males using the reasonable person standard. Females tended to find more harassment than males, but psychological injury and legal standard had little impact on females’ legal decisions. We discuss these findings in light of the positive relationship often observed between the plaintiff’s injury severity level and pro-plaintiff verdicts. 相似文献

The Persistence of Sperm and the Development of Time Since Intercourse (TSI) Guidelines in Sexual Assault Cases at Forensic Science Ireland,Dublin, Ireland 下载免费PDF全文
David G. Casey Ph.D. Katarina Domijan Ph.D. Sarah MacNeill B.Sc. Damien Rizet M.Sc. Declan O'Connell B.Sc. Jennifer Ryan Ph.D. 《Journal of forensic sciences》2017,62(3):585-592
The persistence of sperm using confirmatory microscopic analysis, the persistence of sperm with tails, time since intercourse (TSI) analysis, and results from the acid phosphatase (AP) reaction from approximately 5581 swabs taken from circa 1450 sexual assault cases are presented. The observed proportions of sperm in the vagina and anus declines significantly after 48 h TSI, and sperm on oral swabs were observed up to 15 h TSI. The AP reaction as a predictor of sperm on intimate swabs is questioned. All AP reaction times gave a low true positive rate; 23% of sperm‐positive swabs gave a negative AP reaction time. We show the AP reaction is an unsafe and an unreliable predictor of sperm on intimate swabs. We propose that TSI not AP informs precase assessment and the evaluative approach for sexual assault cases. To help inform an evaluative approach, TSI guidelines are presented. 相似文献

Through an adaptation of a terrorism risk assessment model, this article develops an initial proactive product counterfeiting risk assessment that is designed to focus upon a specific product’s risk for being counterfeited. The goal of developing this risk assessment is to help corporations identify the products that are most at risk for counterfeiting, thereby giving them the ability to focus their resources in the areas where the greatest opportunities for crime are present. This risk assessment is intended to serve as the first line of defence in a comprehensive and proactive brand owner strategy centred on identifying product-specific counterfeiting risk. The assessment comprises three factors that, together, capture a product’s counterfeiting risk level: the threat of product counterfeiting, the brand owner’s vulnerability to product counterfeiting and the potential consequences of a counterfeit product entering the market and reaching consumers. 相似文献

Travelers are a migratory subgroup of homeless youth who may be especially prone to engaging in risky behavior. This study
compared the substance use and sexual behavior of young homeless travelers and non-travelers to evaluate the extent and possible
sources of travelers’ increased risk. Data came from face-to-face interviews with 419 homeless youth (36.6% female, 34.0%
white, 23.9% African American, and 20.0% Hispanic) between the ages of 13 and 24 years (M = 20.1 years, SD = 2.5) who were randomly sampled from 41 shelters, drop-in centers, and street sites in Los Angeles. Travelers
were almost twice as likely as non-travelers to exhibit recent heavy drinking, 37% more likely to exhibit recent marijuana
use, and five times as likely to have injected drugs. Travelers also had more recent sex partners and were more likely to
report having casual or need-based sexual partners and combining sex with substance use. Mediation analyses suggest that travelers’
deviant peer associations and disconnection to conventional individuals and institutions may drive their elevated substance
use. Differences in sexual risk behaviors are likely attributable to demographic differences between the two groups. Overall,
these differences between travelers and non-travelers suggest different service needs and the need for different service approaches. 相似文献

We use Canadian data linking information on venture capital (VC) financing with firm-level administrative data to compare performance of VC-backed and non-VC-backed firms. The richness of the data allows us to incorporate a wide range of firm-level information into creating a control group based on propensity-score matching. In particular, we use typical covariates reflecting firm performance and characteristics (e.g., size, age, industry, location) as well as measures of firm-level innovation such as research and development (R&D) expenditures that are often thought to be associated with the potential for high growth and the probability of receiving VC financing. Our results show R&D expenditures not only attract VC, but are also increased more intensely for VC-backed firms than non-VC-backed counterparts over the short-run. Further, we show VC-backed firms enjoy greater growth in wages and scale over the 5-year period. Overall, our results provide empirical evidence that VC financing is associated with the acceleration of the innovation and commercialization process accompanied by greater growth in wages and scale. 相似文献
