ABSTRACTLike many Republican presidential candidates before him, Donald J. Trump campaigned on a pro-business, anti-regulation platform, and since his election in November 2016, he has directed his administration to move forward with deregulation in many arenas, including consumer financial protections, environmental controls, and workplace safety among others. Past efforts to roll back regulations governing certain industries, such as the savings and loan and the mortgage industries, have had harmful consequences for the general public or for specific interest groups. In this study, we review what the Trump administration has accomplished with regard to deregulation to date. Then, based on past deregulatory fiascos, we theorize the harmful collateral consequences that may result from this most recent swing of the regulatory-deregulatory pendulum. 相似文献

This article argues that Donald Trump’s Asian strategy hardly marks a radical transformation from Barack Obama’s ‘pivot to Asia’. This is because the ‘pivot to Asia’ never really existed. Although Obama was successful in building legitimacy for the strategy through international norms, he failed to translate his lofty rhetoric into practice. Much of his original pivot components (building a constructive relationship with China, coordinating with Asian allies and multilateralism in the Association of South East Asian Nations and the Trans-Pacific Partnership) has either failed or did not live up to expectations. Donald Trump was adamant that the Asian pivot was a bad strategy and that he would not follow it. But although he completely discarded Obama’s legitimization of the rebalance (as Trump speaks pragmatically and does not care about international norms), in actuality he has followed many of Obama’s policies, and even improved on some of them. That being said, Trump’s ‘pivot actions’ appear to be erratic, pragmatic short-term actions rather than a meticulously planned long-term strategy similar to Obama’s rebalance (which did not materialize). Thus, while Obama failed to transform the pivot into an effective strategy, neither is Trump’s effectiveness backed by a coherent Asian strategy. 相似文献

AbstractThis article reports and discusses the results of a study that investigated photographic images of children in five online terrorist magazines to understand the roles of children in these groups. The analysis encompasses issues of Inspire, Dabiq, Jihad Recollections (JR), Azan, and Gaidi Mtanni (GM) from 2009 to 2016. The total number of images was ninety-four. A news value framework was applied that systematically investigated what values the images held that resulted in them being “newsworthy” enough to be published. This article discusses the key findings, which were that Dabiq distinguished different roles for boys and girls, portrayed fierce and prestigious boy child perpetrators, and children flourishing under the caliphate; Inspire and Azan focused on portraying children as victims of Western-backed warfare; GM portrayed children supporting the cause peacefully; and JR contained no re-occurring findings. 相似文献

The horizontal displacement of the human body resulting from fatal fall from a height is an important variable commonly used to inversely determine the cause or identify other forensic aspects of the fall. When examining the horizontal displacement, the wind effect is generally ignored. This technical note reports analytical modeling of the falling process, utilizing previous measurements of wind force acting on the human body, for determining the functional relationship between the wind speed and the horizontal displacement in the falling process. The result reveals that it does not take extremely rare wind conditions to cause a considerable shift of the human body, highlighting the importance to consider wind as a factor in investigations of fatal falls. 相似文献

Minutiae are small distinguishing features found along every ridge flow, which make each friction ridge print unique. The most common friction ridge prints found at the crime scene are fingerprints; therefore, the most of the minutiae studies are focused exactly on this kind of prints. The authors believe that further examination and enlargement of the palm print database could result in better use of the palm prints for personal identification. We analyzed a total of 160 palm prints from 40 females and 40 males aged between 18 and 70 years from Slovakia. For the evaluation of the minutiae, the area of the hypothenar had to be marked out. The classification of the minutiae used for this study was based on a modified version of the classification system using the total of 13 types of minutiae. The frequency of every minutiae type was calculated and, using the chi-square test with Yates's correction, bilateral and sex differences were assessed. The relationship between the different types of minutiae was examined with Pearson's correlation test. During the initial phases of the identification process, the focus should be on the least common types of minutiae (Y or M and return), which were found not to correlate; thus, their mutual occurrence is random (e.g., overlap—Y or M, crossbar—return, or Y or M—dock). The results of the present study show which specific minutiae types are the most suitable for personal identification. These findings may be beneficial in more effective outcome of the identification process. 相似文献

ABSTRACTRecently, “problem-solving” courts have been developed as an alternative to imprisonment. They are often called “specialty” courts because they process and divert into treatment programs offenders who are seen as different from the general criminal population, such as those with mental health or drug problems, those who are homeless or veterans, and those who engage in domestic violence. Based on a 2017 national survey of 1,000 respondents, the current study examines overall public support for rehabilitation as a goal of corrections and then focuses specifically on support for different types of specialty courts. The analysis reveals that the American public endorses not only the rehabilitative ideal but also the use of problem-solving courts. Further, with only minimal variation, strong support for these courts appears to exist regardless of political orientation and sociodemographic characteristics. 相似文献

AbstractDespite shared historical experience and cultural proximity, the Visegrad group (V4) struggles to institutionalise its cooperation through stable mechanisms ensuring internal cohesion and external credibility. This is especially evident in the field of security and defence, which requires a shared strategic vision, in particular, common norms regarding the legitimate use of military force. While in the 1990s the four countries exhibited solidarity and unity in their collective ambition under the narrative of the ‘Return to Europe’, their general perception of security threats and strategic culture prevents deeper integration into a security community. 相似文献
