Four aspects of Donald Trump's hijack of the Republican party are examined. First, how he used unconventional techniques, usually associated with some ‘reality’ television programmes, to become the leading candidate in the pre‐primary debates. He could thereby develop ‘momentum’ before the primaries began despite his limited support among Republican activists. Second, how his insurgency differed from the party's takeover in 1964 by supporters of Barry Goldwater. Third, how the Republicans have replaced the Democrats since the early 1980s as the party with a less cohesive potential coalition among voters, with the result that internal party relations became more conflictual throughout the period. Finally, that internal conflict has been intensified by two factors in those decades: the prevalence of divided government, which has made it virtually impossible to impose a truly conservative agenda on federal government policy, and the impact of forty years of stagnating real incomes for many middle‐income Americans. 相似文献

Supporters of open data believe that free and complete access to research data is beneficial for science, public policy, and society. In environmental science and policy, open data systems can enable relevant research and inform evidence‐based governmental decisions. This article examines the unlikely case of Brazil's National Institute for Space Research's transition toward an open data model. Considering Brazil's young democracy, incipient practice of government transparency and accountability, and lacking a tradition of science‐policy dialogue, this case is a striking example of how open data can support public debate by making information about forest cover widely available. The case shows the benefits and challenges of developing such open data systems, and highlights the various forms of accessibility involved in making data available to the public. 相似文献

The Spanish legislative election of 2015 speaks of change. This is the end of the traditional two-party system and the beginning of a new political era marked by institutional renewal. The Socialist Party and the Partido Popular have both lost significant parliamentary force, whereas two new parties (Podemos, and Ciudadanos) are now crucial to ensure stable government majorities. This new parliamentary scenario seems to better mirror the political pluralism of a changing society which has already demonstrated for change in striking events such as the 15-M Movement. However, political parties are far from showing conciliatory aspirations, possibly because a new election is suddenly a realistic option. This report outlines the political context of the election, indicates the main topics during the campaign and discusses the results. 相似文献

Research has shown that college women are at considerable risk for sexual assault by dating partners, and studies have shown early detection of threat risk cues is an important factor in rape avoidance. This study examined how men and women process sexual encounters in a date rape situation and how they differ in interpretation of cues and response decision-making using Crick and Dodge’s (1994) model of social information processing (SIP). Participants listened to an audio vignette depicting a female resisting sexual contact as the male continues to make sexual advances. The vignette was paused at a point in which there is ambiguity concerning the sexual intentions of the actors, and multiple choice/forced answer questions reflecting five stages in social information processing (causal and intent interpretation, goal clarification, response decision, response efficacy, and response evaluation) were administered. Analyses revealed males and females significantly differed in all SIP stages, and emotional reaction was a significant predictor of response decision. Implications of the findings were discussed. 相似文献

This study examines domestic violence and aims at increasing women’s awareness of it. The authors collected data from 1039 married women at 12 Family Health Centers (FHCs) in Konya, Turkey. Of all women, 39.9 % reported the type of violence given by their husbands as verbal, 31.7 % as emotional, 23.9 % as physical, 13.5 % as sexual and economic violence. While 33 % cited jealousy as a reason for domestic violence, 10.4 % reported to apply to a police station, and 12.2 % to a health center. After experiencing violence, 40 % were found to know how to apply to a state agency while only 1 % reported to know about183, the violence hotline in Turkey. Furthermore, only 9 % were detected to know about legal regulations protecting women and families, 6.2 % to be aware of the Turkish penal code, and 3.5 % to know about the Turkish civil code. However, only 2 % of participants responded correctly, but incompletely to the items in the questionnaire regarding legal changes. 相似文献

Historically, in crimes involving heavy caliber rifles, only conventional factory‐made versions have been used. However, in recent years the number of homemade long‐barreled rifles is increasing. The characteristics of two such firearms that have been submitted to the Turkish Criminal Laboratory are discussed here. When the main parts of the guns were examined in detail, it was noted that nearly all of the parts had been made carelessly, with several structural defects visible. It was determined that the homemade heavy caliber rifles were unfit for efficient use and it was possible that they could have seriously harmed the shooter had they been fired. The development of these kinds of gun and the possibility of their use spreading throughout the country in terrorist attacks could cause a serious threat to national security. 相似文献

Erythritol tetranitrate (ETN), an ester of nitric acid and erythritol, is a solid crystalline explosive with high explosive performance. Although it has never been used in any industrial or military application, it has become one of the most prepared and misused improvise explosives. In this study, several analytical techniques were explored to facilitate analysis in forensic laboratories. FTIR and Raman spectrometry measurements expand existing data and bring more detailed assignment of bands through the parallel study of erythritol [15N4] tetranitrate. In the case of powder diffraction, recently published data were verified, and 1H, 13C, and 15N NMR spectra are discussed in detail. The technique of electrospray ionization tandem mass spectrometry was successfully used for the analysis of ETN. Described methods allow fast, versatile, and reliable detection or analysis of samples containing erythritol tetranitrate in forensic laboratories. 相似文献

Inmates represent a vulnerable population with increased rates of trauma and posttraumatic stress disorder (PTSD). However, little is known about the rates of trauma and PTSD among male inmates with acute psychiatric illness. This prospective, randomized study was conducted to assess the current rates of trauma and PTSD in this population. The sample consisted of 48 patients admitted to a hospital jail psychiatry service in New York City. Subjects were administered the Life Stressor Checklist‐Revised and the Structured Clinical Interview for DSM‐IV‐TR Disorders, PTSD Module (SCID‐I). The rate of PTSD diagnosis via SCID‐I was 46.2% as compared to 2.1% diagnosis via clinical interview. All participants reported a history of at least one stressful and/or traumatic event, and many of these events occurred during incarceration. These results demonstrate that a great deal of trauma and PTSD goes unrecognized and untreated in this population, indicating the need for more effective treatment interventions. 相似文献

This article argues that cartelised coordination inside Chilean congressional committees is important for understanding the success rates of presidential initiatives. By way of an analysis of the amendment process undertaken both in the Chamber and Senate committees in the Chilean Congress during 2006–10, the authors review the approval patterns of legislative amendments. The analysis suggests two chief findings: coordination between government parties and the executive is crucial for the success of amendment; and the opposition’s success in generating legal transformations depends on the construction of inter-coalition alliances. It is hoped that the perspective offered here will contribute to the current literature on cartel party theory in Latin America. 相似文献
