We examined student responses to three new instructors who taught a lesbian, gay, bisexual, and transgender (LGBT) ally development course as described in a study by Ji, Finnessy, and Dubois (2009). Our analysis of the responses indicated that students did improve as LGBT allies in ways similar to those reported in the 2009 study. The findings suggest that the course could be disseminated provided that instructors actively encouraged students to engage in experiences that develop their LGBT ally identities.  相似文献

The aim of this paper is to shed additional light on the determinants of budget transparency in local governments. Our work is based on a Likert-type survey questionnaire specifically designed to measure budget transparency in small municipalities. The questionnaire is based on the IMF's revised Code of Good Practices on Fiscal Transparency (2007). Results from 33 Galician municipalities are used to assess its internal consistency and to test a battery of hypotheses on the determinants of budget transparency. While several previous findings of the literature are confirmed, some new results are also obtained.  相似文献

ABSTRACT

Does the executive's institutional hegemony represent a risk to the survival of democracy? By hegemony, we refer to the president's ability to control other institutions, particularly the legislature and judiciary. To answer this question, we develop two indices of presidential hegemony and analyze the duration of democratic regimes in 18 Latin American countries between 1925 and 2016. The results show that executive hegemony is a major driver of democratic instability. This finding is robust to non-linear effects and to potential endogeneity in the relationship between presidential power and democratic backsliding. Our findings challenge traditional concerns about executive-legislative deadlock, and have significant implications for the nascent literature on democratic backsliding, which highlights executive aggrandizement as a risk factor.  相似文献

This article explains why parliamentary groups invite interest groups to the parliamentary arena. It argues that interest groups’ access to committees not only reflects policy-makers’ need for information and expertise but also party preferences and institutional factors such as the type of government, parliamentary committee structure and committee agenda capacity. Results show that interest groups’ access to the parliamentary arena increases under minority governments, in the case of highly conflictual issues, and when the number of permanent committees increases. Also, results demonstrate that parliamentary groups invite interest organisations following different logics – problem-solving or confrontation logic – depending on the type of functions they have to perform – legislative and oversight activities. The article uses a novel, comprehensive database with information on the appearances of all interest groups in the Spanish parliament from 1996 to 2015.  相似文献

Many formulae are available to estimate the relation between the potassium ([K+]) and hypoxantine ([Hx]) concentration in the vitreous humour and the postmortem interval (PMI). Typically these have been based on a correlation test and linear regression using the postmortal interval as the independent variable and [K+] or [Hx] as the dependent variable in order to estimate the confidence interval. However, a recent study has shown that a more precise measurement of PMI can be obtained if [K+] is used as the independent variable. The regression lines obtained from the most recent deceased subjects with forensic relevance received for autopsy in the Institute of Legal Medicine are [K+] = 5.589 + 0.174PMI and [Hx] = 26.459 + 3.017PMI, by changing the variables, we obtain PMI=3.967[K+] - 19.186 (R2 = 0.688, P < 0.001) and PMI = 0.172 [Hx] + 0.170 (R2 = 0.518, P < 0.001). In this paper we propose the cause of death as an extra factor which modifies the relationship and gives even greater precision in estimating PMI. In cases of death by hanging the results are considerably improved with [K+] = 5.224 + 0.225PMI and [Hx] = 15.161+4.957PMI, respectively, and consequently, PMI = 3.631[K+] - 17.334 (R2 = 0.818, P< 0.001) and PMI = 0.153[Hx] - 0.368 (R2 = 0.757, P < 0.001): the slope is less and the precision is obviously enhanced.  相似文献

Purpose

A growing number of studies have examined the immigrant paradox with respect to antisocial behavior and crime in the United States. However, there remains a need for a comprehensive examination of the intergenerational nature of violence and antisocial behavior among immigrants using population-based samples.

Methods

The present study, employing data from Wave I and II data of the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC), sought to address these gaps by examining the prevalence of nonviolent criminal and violent antisocial behavior among first, second, and third-generation immigrants and compare these to the prevalence found among non-immigrants and each other in the United States.

Results

There is clear evidence of an intergenerational severity-based gradient in the relationship between immigrant status and antisocial behavior and crime. The protective effect of nativity is far-and-away strongest among first-generation immigrants, attenuates substantially among second-generation immigrants, and essentially disappears among third-generation immigrants. These patterns were also stable across gender.

Conclusion

The present study is among the first to examine the intergenerational nature of antisocial behavior and crime among immigrants using population-based samples. Results provide robust evidence that nativity as a protective factor for immigrants wanes with each successive generation.  相似文献

This article examines the relationships between gender and technology in Spanish feminist praxis online and argues that different perspectives on online feminist community-building offer distinct responses to cyberactivism, which is considered central to sustaining efforts for social change. To ascertain whether Spanish virtual communities and cyberactivism have the potential to address the challenges posed by the relations between gender and technology, we analyse feminist scholar Remedios Zafra's theoretical proposals, and the different ways in which this theory intersects with the cyberactivism put forth by two feminist web portals, Ciudad de Mujeres and Mujeres en Red. We will discuss to what degree particular Spanish feminist theory and practice online adapts to or challenges utopianism regarding the liberating potential of technology. We will also examine how, in the face of critical arguments about such liberatory possibilities, two options present themselves for women's effective use of technology: inhabiting or occupying the web through the construction of feminist communities online.  相似文献

In multiparty legislatures, the largest party or coalition may fall short of controlling a majority of plenary seats. However, plurality‐led congresses generally endow the largest parties with extensive agenda‐setting prerogatives, even when plenary majorities are lacking. In this article, we present a model and compelling evidence describing changes in the strategic behavior of committee chairs when majority control is lost. Using a dataset that includes all the bills proposed to the Argentine House in the last 25 years, we estimate success in committee in majority‐ and plurality‐led congresses. We provide extensive evidence that the loss of majority control reduces the importance of the median voter of the plurality party while improving the success of the median committee voter.  相似文献

Penile strangulation or entrapment is an unusual entity that requires urgent treatment due to its potential complications. Several cases have been reported in the medical literature, some of them describing serious injuries such as necrosis, gangrene, and amputation of the penis. However, as far as we know, no fatal cases have been described before. We present the death of an adult male secondary to the complications due to penile strangulation with a plastic bottle neck. The time of incarceration was unknown, but according to a witness it could be about 10 to 14 days. The findings of autopsy were penile strangulation, necrosis of the penis, acute pyelonephritis, and bronchopneumonia. The subject's refusal to ask for medical help was the cause of this atypical evolution.  相似文献

In recent years, alcohol consumption has been considered an important public health problem. Ethanol, the alcohol used in beverages, is a drug that affects the central nervous system (CNS) and impairs driving skills and co-ordination, increasing risk of deaths and injuries derived from crashes and road accidents. Consumption of alcoholic beverages is implicated with premature deaths, injuries and damages caused by motor vehicle crashes, which result in high costs to government and society. Considering that alcohol consumption is the main responsible factor for deaths and disabilities in young people, the aim of this work was to evaluate the prevalence of blood alcohol in offenders and/or fatal and non-fatal victims of traffic occurrences in the region of Ribeir?o Preto, S?o Paulo State, from 2005 to 2007. The results revealed that in 2134 cases investigated, blood alcohol positivity was generally found in young adults, 25-45 years old and male. The study showed the high risk of drinking and driving and the importance in establishing actions of prevention and intervention to promote the reduction in the number of traffic occurrences related to consumption of alcoholic beverages.  相似文献
