Scholars have recently debated whether non-recognition is a blessing or a curse for democracy. Some suggest that lack of recognition forces political elites to democratize and acquire internal legitimacy to compensate for the lack of external legitimacy. Others suggest that democratization is used as a strategy by which to acquire international recognition. Still others claim that non-recognition obliges unrecognized states to rely on a patron state which, in turn, hinders the quality of democracy. To contribute to this discussion, we have conducted an in-depth case study. Focusing on democratic quality in Northern Cyprus from 2010 to 2016, it is observed that reliance on a patron state leads to dynamics of tutelage, in turn hindering the quality of democracy.  相似文献

In this introduction, we review the literature on intellectual property rights and access to medicines, identifying two distinct generations of research. The first generation analyzes the origins of new intellectual property rules, in particular the World Trade Organization’s Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), and the significance of TRIPS to developing countries. The second generation examines national-level experiences, as countries adjust their laws and practices to conform to TRIPS. Based on the insights provided by the articles in the special issue, we contribute to the second generation by considering a pair of overarching sets of issues. First, we highlight the domestic political challenges that affect how countries go about implementing their new obligations under TRIPS. We argue that alliances and coalitions are necessary to underpin the use of policy instruments designed to conform to TRIPS while taking into account local conditions and needs, and we present insights that allow us to understand why alliances and coalitions are difficult to construct and sustain in this area. Second, we explain why policies that many countries adopt in response to TRIPS often do not generate their desired or intended outcomes. In the last section of the introduction, we review the articles that appear in this special issue.  相似文献

The Singapore Statement on Research Integrity, articulated during the 2nd World Conference on Research Integrity in 2010, encompasses principles that apply to all research endeavours, including the various disciplines that comprise the field of forensic science Singapore Statement on Research Integrity (2010) (https://wcrif.org/guidance/singapore-statement). Cases of research misconduct and breaches of research integrity in any field undermine the trustworthiness of research and make it difficult if not impossible for others to rely upon and replicate research results. Moreover, problems in the research environment, whether in the academic, public, or private sector, can include bullying and harassment, discrimination, abuse of power and corruption, as well as competitive pressures related to employment and status.  相似文献

The media allow crime to infiltrate the public’s consciousness in every conceivable way, thereby playing a major role in shaping the public’s opinion and attitude toward crime and crime issues (Barak, 1995; Fields & Jerin, 1996; Kappeler & Potter, 2005). Reporters constantly talk about crime, and crime related stories dominate the headlines of local and national newspaper outlets (Dowler, 2003; Pizarro et al, 2007). Some of the most highly rated television programs are based on crime plots and people across social, political, and racial demographics are constantly engaged in crime dialogue generated from local or national news stories. When the focus of these mediums is on youth they become even more profound and contentious. The images portrayed conjure up stereotypes that lead to fear and inflammatory remarks that become entrenched into the national lexicon. The current study uses data from the National Opinion Survey of Crime and Justice to test the relationship between crime-related media viewership and fear of victimization within a nationally representative adult sample. Approximately 42.67% of respondents reported regularly watching crime shows and about the same proportion (42.83%) believed their local media paid too much attention to violent crime. In addition to regular crime-show viewership, confidence in the police, gender, and recent contact with the police were associated with fear of victimization. This article adds to an existing body of research through a largely unexplored area in the administration of justice. It does so within the context of the U.S. juvenile justice system.  相似文献

Motivational interviewing (MI) is a communication style focused on enhancing clients’ own motivation towards change. In the justice system MI has evidence to support that it enhances communication and change behaviors in youth. As most MI training is designed for healthcare settings training and implementation of MI must be adapted to fit the juvenile justice model. This includes both rehabilitation and restorative justice. Here we describe the details that allowed one county small county in Pennsylvania to roll out MI training and initial skills review in less than 6 months. The case reviews the details of planning, trainings, and timing of activities. We then discuss what elements of those details fit into a greater implementation plan that may be applied elsewhere. Four key elements were instrumental to implementation: 1) appreciation of JPO time constraints, 2) cost containment 3) using blending to enhance JPO flexibility with MI use, and 4) policies that normalize use of MI. This outline may assist other courts in their own implementation efforts.  相似文献

Postmortem stability of DNA   总被引:11,自引:0,他引:11  
High-molecular-weight DNA was recovered postmortem in sufficient quantities from various human organ tissues as well as from blood, although not all organs were equally well suitable. Good DNA stability was found in brain cortex, lymph nodes and psoas muscle over a period of three weeks postmortem. Spleen and kidney showed good DNA stability up to five days postmortem but after longer periods, rapid degradation was observed. Yields of DNA from blood were not consistent because of the non homogeneity of samples. Blood clots were rich with DNA. Generally, the amount of degraded DNA correlated directly with the duration of the postmortem period. However in some cases, DNA degradation was already prominent after a short period. However in some cases, DNA degradation was already prominent after a short period. Case histories showed that high environmental temperature at the site of death and/or infectious diseases prior to death were the main factors for rapid autolysis. Gradual disappearance to complete loss of the long fragments (15-23 kb) was observed in DNA fingerprinting using the minisatellite probe 33.15. No extra-bands were noted, thus excluding erroneous conclusions. However, evidentiary value of older samples was lower.  相似文献

Headspace gas chromatography was used to determine the concentration of ethanol and methanol in blood samples from 519 individuals suspected of drinking and driving in Sweden where the legal alcohol limit is 0.50 mg/g in whole blood (11 mmol/l). The concentration of ethanol in blood ranged from 0.01 to 3.52 mg/g with a mean of 1.83 +/- 0.82 mg/g (+/- S.D.). The frequency distribution was symmetrical about the mean but deviated from normality. A plot of the same data on normal probability paper indicated that it might be composed of two subpopulations (bimodal). The concentration of methanol in the same blood specimens ranged from 1 to 23 mg/l with a mean of 7.3 +/- 3.6 mg/l (+/- S.D.) and this distribution was markedly skew (+). The concentration of ethanol (x) and methanol (y) were positively correlated (r = 0.47, P less than 0.001) and implies that 22% (r2) of the variance in blood-methanol can be attributed to its linear regression on blood-ethanol. The regression equation was y = 3.6 + 2.1 x and the standard error estimate was 0.32 mg/l. This large scatter precludes making reliable estimates of blood-methanol concentration from measurements of blood-ethanol concentration and the regression equation. But higher blood-methanol concentrations are definitely associated with higher blood-ethanol in this sample of Swedish drinking drivers. Frequent exposure to methanol and its toxic products of metabolism, formaldehyde and formic acid, might constitute an additional health risk associated with heavy drinking in predisposed individuals. The determination of methanol in blood of drinking drivers in addition to ethanol could indicate long-standing ethanol intoxication and therefore potential problem drinkers or alcoholics.  相似文献
