The backings of 90 black electrical tapes were analyzed to evaluate the chemical components of these films, the ability of individual techniques to discriminate samples, and the ability of the techniques combined to distinguish samples. The techniques utilized and their respective discrimination results were stereomicroscopy and physical measurements, to include observation of surface features of the backing, width, and thickness measurements (c. 64%); Fourier transform infrared spectroscopy (FTIR) using a microscope accessory (c. 83%); pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS; c. 81%); and scanning electron microscopy/energy-dispersive spectroscopy (SEM/EDS; c. 87%). Ninety-four percent of the backings were discriminated through this combination of analytical methods. Finally, evaluating these results in conjunction with previously published data on the analysis of the adhesives from the same set of electrical tapes provided an overall discrimination of nearly 96%. 相似文献

The Coalition government made a commitment to review employment law to ensure flexibility for both parties and enhance business's competitiveness. This led the prime minister to ask venture capitalist Adrian Beecroft to undertake the task of identifying the areas of employment law that presented the greatest burden, and making recommendations for reform. The Beecroft report identifies 16 areas for reform, but the lack of evidence to support his conclusions severely undermines his case. The challenge of increasing employment in a stagnant economy is substantial, and Beecroft's recommendations, if implemented, are unlikely to make a difference. Businesses need to see increased demand and access to finance if they are to take on more workers, but government must also develop a long‐term vision of the UK labour market and address weaknesses that existed before the financial crisis. 相似文献

Commercial‐off‐the‐shelf (COTS) materials were evaluated as surface samplers for the Department of Homeland Security Chemical Forensics Program. The program helps evidence collectors identify trace chemical residues at incident scenes. COTS items are widely available, produced in large lots, and with strict controls. Chemical attribution signatures were collected from common surfaces. Eight tape lift candidates were considered, five were chosen based on performance and tested for analytical interferences and extraction efficiencies with 14 chemicals. Three products (duct tape, print lifters, command strips) were evaluated for uptake from common interior surfaces (glass, tile, ABS plastic). Duct tape provided highest recoveries across all surfaces. Even the most volatile analytes were detected in the ABS plastic samples (nondetections in others), regardless of tape lift material used. The porous plastic substrate provides better target retention than glass and tile surfaces. Forensic field operators should sample surfaces made of ABS plastic (keyboards, remotes, phones, etc.) whenever possible. 相似文献

Given the unprecedented scale of intergovernmental development funding and the importance of institutional quality for human well‐being, it is imperative to precisely understand the impact of development funds on corruption. In Europe, European Union (EU) Funds provide a boost to public spending in recipient member states while introducing additional corruption controls. We investigate whether EU Funds increase high‐level corruption in the Czech Republic and Hungary in 2009–2012. We analyze newly collected data from over 100,000 public procurement contracts to develop objective corruption risk indicators and link them to agency level data in the public sector. Propensity score matching estimations suggest that EU funds increase corruption risk by up to 34 percent. The negative effects are largely attributable to overly formalistic compliance and EU Funds overriding domestic accountability mechanisms in public organizations entirely dependent on external funds. The policy implications are profound: governments should reduce barriers to market entry by lowering red tape and prevent excessive concentration of funds. 相似文献

A 19‐year‐old woman was found dead with her face and head wrapped in plastic adhesive tape in a cupboard beside an opened helium cylinder. Despite the alleged presence of a suicide message on a social networking website, the unusual circumstances raised the possibility at the time of autopsy of either accidental death from sexual asphyxia or homicide. A carefully monitored reenactment demonstrated, however, that the type of commercial adhesive tape that had been used did not cause complete airway obstruction and that it was possible to wrap a considerable length of tape around the head and neck with the breath held. All of the features at autopsy were, therefore, compatible with self‐infliction. Asphyxial death was attributed to the combined effects of smothering from tape and anoxia from helium, an extremely rare combination in young females. 相似文献

Crowdsourcing and regulatory reviews: A new way of challenging red tape in British government? 下载免费PDF全文
Much has been said about the appeal of digital government devices to enhance consultation on rulemaking. This paper explores the most ambitious attempt by the UK central government so far to draw on “crowdsourcing” to consult and act on regulatory reform, the “Red Tape Challenge.” We find that the results of this exercise do not represent any major change to traditional challenges to consultation processes. Instead, we suggest that the extensive institutional arrangements for crowdsourcing were hardly significant in informing actual policy responses: neither the tone of the crowdsourced comments, the direction of the majority views, nor specific comments were seen to matter. Instead, it was processes within the executive that shaped the overall governmental responses to this initiative. The findings, therefore, provoke wider debates about the use of social media in rulemaking and consultation exercises. 相似文献
