Supplier behaviour and public contracting in the English agency nursing market

The worldwide expansion in the use of private firms to deliver public services and infrastructure has promoted a substantial literature on public sector contract and relationship management. This literature is currently dominated by the notion that supplier relationships should be based upon trust. Less prominent are more sceptical approaches that emphasize the need to assiduously manage potential supplier exploitation and opportunism. This article addresses this imbalance by focusing upon the recent experience of the English National Health Service (NHS) in its dealings with its nursing agencies. Between 1997 and 2001, the NHS was subjected to considerable exploitation and opportunism. This forced managers to adopt a supply strategy based upon an assiduous use of e-auctions, framework agreements and quality audits. The article assesses the effectiveness of this strategy and reflects upon whether a more defensive approach to contract and relationship management offers a viable alternative to one based upon trust.

Evaluating competitiveness impacts of regulatory reforms in the Brazilian cashew industry

This work evaluates regulatory impacts on the Brazilian cashew industry through the pilot use of CIBER, a value-chain-based approach, to identify and measure regulatory constraints and to enact regulatory reforms in donor-funded development projects. Drawing from secondary sources complemented by primary field research, all the CIBER-suggested steps are followed. The results reveal that tax and credit regulations should be priorities to improve the competitiveness of the cashew business in Brazil, and that CIBER can be an effective tool to expand industry analysis and to design reform strategies towards improved competitiveness.     

Anticorruption Commissions: The “Hong Kong Model” Revisited

The international donor community has, in the last few years, discouraged the use of specialised anticorruption bodies as the spearhead of the attack on corruption, for reasons that have never been sufficiently explained or critically examined.

The academic objections to replicating the Hong Kong solution in other countries are first, that the context in which corruption occurs in Hong Kong is unique and for that reason the solution cannot be exported; second, that the remedy is too strong, too dangerous to be applied elsewhere. The risk of an anticorruption body like the Independent Commission Against Corruption (ICAC) becoming an instrument of political oppression is simply too great to warrant its use; third, establishing and maintaining an anticorruption body at the strength required to deal with corruption is said to be inordinately costly. The fourth objection is a frontal assault on the very concept of an anticorruption body as a means of tackling corruption. The answer, according to this view, lies in governance and policy reform.

These objections have been adopted by the international donor institutions, apparently for reasons that have little to do with any in-depth analysis of the effectiveness of successful anticorruption bodies.

Over the past decade numerous alternative methods of tackling corruption have been proposed and attempted. The results have been disappointing.

By contrast, Hong Kong remains firmly on top of its corruption problem, the ICAC continues to enjoy a public support of 98–99% and this special administrative region of China continues to improve its standing in Transparency International's Corruption Perceptions Index (CPI), one of the few places in the world to do so. In Botswana where the Directorate on Corruption and Economic Crime (DCEC) was modelled on the ICAC with modifications, the country is rated the least corrupt in Africa by a considerable margin and is in the top 25% of countries worldwide. Madagascar which modelled its Bureau Indépendant Anti-Corruption (BIANCO) even more closely on the HK ICAC has made good progress in the short time it has been operational.

Is it not time to reconsider the rejection by the donor community of the “Hong Kong model?” Should we not be examining more profoundly than previously how Hong Kong managed to get and stay on top of corruption? Should the donor community not be helping those countries that have decided they want a separate anticorruption body get the design and the operational policies and practices right?

Voltammetric determination of cocaine in confiscated samples using a cobalt hexacyanoferrate film-modified electrode

In this work, a fast, non destructive voltammetric method for cocaine detection in acetonitrile medium using a platinum disk electrode chemically modified with cobalt-hexacyanoferrate (CoHCFe) film is described. The deposition of CoHCFe film at platinum disk (working electrode) was carried out in aqueous solution containing NaClO₄ at 0.1 mol L⁻¹ as supporting electrolite. Stability studies of the film and subsequent voltammetric analysis of cocaine were made in acetonitrile medium with NaClO₄ at 0.1 mol L⁻¹ as supporting electrolite. A reversible interaction between cocaine and CoHCFe at the film produces a proportional decrease of original peak current, due to the formation of a complex between cocaine and cobalt íons, with subsequent partial passivation of the film surface, being the intensity of current decrease used as analytical signal for cocaine. A linear dependence of cocaine detection was carried out in the range from 2.4 × 10⁻⁴ to 1.5 × 10⁻³ mol L⁻¹, with a linear correlation coefficient of 0.994 and a detection limit of 1.4 × 10⁻⁴ mol L⁻¹. The analysis of confiscated samples by the proposed method indicated cocaine levels from 37% to 95% (m/m) and these results were validated by comparison to HPLC technique, being obtained good correlation between both methods.     

Genetic identification of degraded DNA samples buried in different types of soil

Biological samples buried in different types of soil are often found in crime scenes. These samples are usually highly degraded which difficult their analysis. Several factors contribute to the degradation of biological material including temperature variation, humidity, UV light and especially the presence of microorganisms.Blood was collected from three non-related male donors and blood stains were made in fabrics such as jeans, cotton and lycra. Blood stains were dried at room temperature and buried in three different types of soil (sand, marsh and clay), to promote its natural degradation.The buried samples suffered a high degradation over time which difficult their genetic identification. The marshy soil proved to be the most destructive one, leading to rapid degradation of the different analyzed fabrics, which disabled the obtainment of the genetic profiles.     

Increased sensitivity for amplified STR alleles on capillary sequencers with BigDye XTerminator™

Free fluorescent dyes from PCR primers or amplification products can interfere with the interpretation of STR alleles in an electropherograph especially when the profiles have a low signal intensity. These artefacts can be removed by using a simple procedure based on BigDye^® XTerminator™. This procedure requires limited amounts of PCR product, allows to do several loadings on a capillary sequencer starting from the same purified PCR product and also increases the sensitivity for detection of less amplified loci.     

Study of Short- and Long-Term Storage of Teeth and Its Influence on DNA

Abstract:  DNA degradation can interfere with the resolution of forensic cases. Allelic dropout often reduces the opportunity for adequate comparisons between degraded and reference samples. This study analyzed DNA degradation in 24 extracted teeth after storage at room temperature for 0, 2, 5, and 10 years. DNA concentration, quantified by dot-blot hybridization, declined significantly for the first 2 years, but there was no significant further degradation from the second to the tenth year of storage. COfiler™ analysis was used and the allelic dropout ratio for the amelogenin locus relative to CSF1PO locus was also estimated. Statistically significant differences were found between fresh teeth and teeth from the 2- and 5-year groups but not from the 10-year group. Under our storage conditions most of the DNA degradation occurred during the first 2 years. Further research is needed to control for individual and external factors that could affect DNA.
