Forensic DNA databases are implemented worldwide and used increasingly. Part of this increasing usage is arguably a matter of function creep. Function creep refers to changes in, and especially additions to, the use of a technology. In this article we explore the notion of function creep as we discuss why and how it has taken place on forensic DNA databases. We also consider what future function creep it is possible to envisage. As even security enhancing technologies may contribute to insecurities, what safeguards should be in place to render function creep governable? We use the Norwegian DNA database, expanded considerably as recently as September 2008, as our primary case for discussion. Additionally we use examples from the English and Welsh DNA database which, considered world leading, may be an indication of where other DNA databases are heading. The article isn't data-driven but draws on a wide spectrum of data: governmental documents, public and Parliamentary debates, and interviews.  相似文献

Think tanks in the Nordic countries are now frequently referred to in national media, among decision-makers as well as in academic communities. Based on the literature on think tanks, a consensual and adversarial perspective on their development is advanced. In support of a consensual perspective, the special issue shows that a number of policy think tanks, which play consensual roles in different policy niches, have emerged in the Nordic countries in recent decades. In support of an adversarial perspective, think tank landscapes in the Nordic countries now include advocacy think tanks from both sides of the political spectrum. The mixed think tank landscapes found in the Nordic countries do not constitute a break with consensual policy-making traditions. Nevertheless, a number of privately funded think tanks, which have increased competition for funding, media visibility and political influence, have supplemented established publicly funded think tanks in particular in Scandinavia.  相似文献

While the number of think tanks in Denmark has increased considerably in recent decades, our knowledge about their visibility in political arenas is limited. The article explores how and why the mentions of private and public think tanks in the parliamentary and media arenas has developed from 2005 to 2018. Building on insights from previous studies of think tanks, publicly funded think tanks are expected to achieve more parliamentary mentions than private think tanks because they are expected to be more heavily influenced by institutionalized norms to target inside actors through parliament. By contrast, privately funded think tanks are expected to achieve more media mentions than public think tanks, because they are policymaking outsiders and emphasize public advocacy over direct influence. Although publicly funded think tanks have been more visible in the parliamentary arena than private think tanks, their visibility has declined. Private think tanks are more visible than public think tanks, but media visibility for privately funded think tanks also drops towards the end of the period. The article concludes that public or private funding cannot fully explain changes in think tank visibility in the two arenas over time. Instead media and parliamentary mentions are driven by a handful of think tanks while most think tanks struggle to achieve and maintain parliamentary and media visibility over time.  相似文献

A mixture of explosives was analyzed by gas chromatography (GC) linked to ultraviolet (UV) spectrophotometry that enabled detection in the range of 178–330 nm. The gas‐phase UV spectra of 2,4,6‐trinitrotoluene (TNT), 2,4‐dinitrotoluene (DNT), ethylene glycol dinitrate (EGDN), glycerine trinitrate (NG, nitroglycerine), triacetone triperoxide (TATP), and pentaerythritol tetranitrate (PETN) were successfully recorded. The most interesting aspect of the current application is that it enabled simultaneous detection of both the target analyte and its decomposition products. At suitable elevated temperatures of the transfer line between the GC instrument and the UV detector, a partial decomposition was accomplished. Detection was made in real time and resulted in overlaid spectra of the mother compound and its decomposition product. Hence, the presented approach added another level to the qualitative identification of the explosives in comparison with traditional methods that relies only on the detection of the target analyte. As expected, the decomposition product of EGDN, NG, and PETN was NO, while TATP degraded to acetone. DNT and TNT did not exhibit any decomposition at the temperatures used.  相似文献

A capillary zone electrophoresis (CZE) method was developed for the analysis of amphetamine and 13 amphetamine analogues. A full factorial design was used to screen for important design variables (i.e. carrier electrolyte concentration, pH, and separation temperature), and a modified simplex was employed in a final optimisation step. The resolution values of the target compounds were used as responses in the screening and optimisation phases. This approach made it possible to control the effects of the design variables on the separation of the target compounds. The best results were obtained using a 100mM Tris/phosphate buffer (pH 3.1) at a separation temperature of 10 degrees C, and the analysis time was 23 min under these conditions. After slight modification, the method also enabled baseline resolution of the most commonly encountered amphetamine derivatives, as well as cocaine and heroin, within 7 min. There was a linear relationship between peak area and concentration for all substances, with correlation coefficients in the range of 0.9975-0.9999. Moreover, the technique was repeatable and exhibited relative standard deviation (R.S.D.) values in the ranges of 0.01-0.11% and 0.54-1.60% for relative migration time and corrected peak area, respectively. Lastly, the method was successfully applied to analyse street samples.  相似文献

While much of the focus of terrorism research is on successful terrorist attacks, the most significant lessons for terrorism prevention may come from examination of terrorist plots and attacks that do not succeed. This article analyzes 176 terrorist plots against American targets that have been thwarted or otherwise failed during the past 25 years. It considers what kinds of intelligence and security measures are most useful in counterterrorism, and argues that the conventional wisdom about why intelligence fails—because analysts and agencies are unable to “connect the dots”—is wrong. Most plots, especially domestic terrorist plots, are not foiled through imaginative analysis, but through conventional law enforcement efforts and aggressive domestic intelligence collection that reveal to authorities just what the plotters are up to.  相似文献

This article is the result of a study aimed at grasping the knowledge of ‘prostitution’ since 1999 when the purchase of sexual services was criminalised in Sweden. Key informants drawn from the police, social services and voluntary organisations, who work in close proximity to prostitution, were interviewed. We focus on how the position of the informant, considering governmental and non-governmental exercise, effects her or his understanding, and reproduction, of the phenomena. The central themes are the question of definition, the importance of exposure and the occurrence of male prostitution. It is suggested that a study of these themes shows how the traditional position of the bad woman as vendor and the invisible man as purchaser is preserved. Hereby all the other constellations, that may as well be considered to be prostitution, remains unproblematized.  相似文献
