Experiments With the Pivot Process for Providing Public Goods

Interest in demand revealing mechanisms for providing public goods has both waned and then renewed over the past two decades. The possibility of using such mechanisms in different venues than originally anticipated sparked the research reported here. The specific motivation for this paper is to conduct a series of simple direct tests of one version of the class of mechanisms. Failure of demand revelation was much more expensive than we had expected, even when compared to previous research with related mechanisms. The reason for this remains an open question.     

Caught in the Act: The Smoking Gun View of Ministerial Responsibility

While any discussion of ministerial responsibility must in part focus on ministerial resignations, finding out when ministers resign is only the tip of the iceberg. A full assessment of ministerial responsibility would look at the relations between ministers and their senior bureaucrats, as discussed in Bill Blick’s article. It would look at the impact of managerialism on ministerial accountability, especially in the light of privatisation and contracting out. It would assess the impact of other mechanisms of accountability, including the senate. The subject of this article must always be put into a broader context. This article concentrates on ministerial resignations drawing on evidence from Britain, Canada, the federal government in Australia and the government of New South Wales. When do ministers resign?     

Is the Torrens System German?

Recently support has grown for the view that the Torrens system of lands titles registration, which has now spread to numerous jurisdictions throughout the world, was actually not Torrens's work at all, but a copy of a German system passed off by him as his own production. This article reviews the evidence, much of which is here discussed for the first time, and concludes that that view is incorrect. Torrens is entitled to the credit for conceiving the principles of the system; for drafting the bill to give effect to them (with the help of a circle of critical reviewers); and for convincing the public and politicians to support it.     

Subjectivity and bias in forensic DNA mixture interpretation

The objectivity of forensic science decision making has received increased attention and scrutiny. However, there are only a few published studies experimentally addressing the potential for contextual bias. Because of the esteem of DNA evidence, it is important to study and assess the impact of subjectivity and bias on DNA mixture interpretation. The study reported here presents empirical data suggesting that DNA mixture interpretation is subjective. When 17 North American expert DNA examiners were asked for their interpretation of data from an adjudicated criminal case in that jurisdiction, they produced inconsistent interpretations. Furthermore, the majority of 'context free' experts disagreed with the laboratory's pre-trial conclusions, suggesting that the extraneous context of the criminal case may have influenced the interpretation of the DNA evidence, thereby showing a biasing effect of contextual information in DNA mixture interpretation.     

Comparative study of electrochromic enhancement of latent fingerprints with existing development techniques

To address the challenge of capturing latent fingerprint evidence from metal surfaces, a new method of latent fingerprint enhancement based on electrochromic polymer films has recently been developed. Here, we present a study comparing the development and visualization of nonvisible fingerprints on stainless steel substrates using this electrochromic enhancement approach with three classical methods (dusting, wet powder, and cyanoacrylate fuming). Two variants of the electrochromic enhancement method were utilized with polyaniline and poly(3,4-ethylenedioxythiophene) as the electrochromic materials. Fingerprint samples were taken from different donors (varying in age and gender) and were exposed to different environments for systematically varied periods of time (up to 28 days). The environments represent plausible evidential scenarios: left under ambient conditions, washed with aqueous soap solution, washed with acetone, submerged in water, and maintained at elevated temperature. The electrochromic enhancement procedure frequently outperformed the traditional methods, particularly for samples exposed to more challenging histories.     

Effect of chloride ion concentration on the galvanic corrosion of α phase brass by eccrine sweat

Inductively coupled plasma mass spectrometry measurement of the relative concentration of sodium, chloride, calcium, and potassium ions in eccrine sweat deposits from 40 donors revealed positive correlations between chloride and sodium (ρ = 0.684, p < 0.01) and chloride and calcium ions (ρ = 0.91, p < 0.01). Correlations between ion concentration and the corrosion of α phase brass by the donated sweat were investigated by visual grading of the degree of corrosion, by measuring the copper/zinc ratio using energy-dispersive X-ray spectroscopy, and from a measurement of the potential difference between corroded and uncorroded brass when a large potential was applied to the uncorroded brass. An increasing copper/zinc ratio (indicative of dezincification) was found to correlate positively to both chloride ion concentration and visual grading of corrosion, while visual grading gave correlations with potential difference measurements that were indicative of the preferential surface oxidation of zinc rather than copper.     

Production goes global,compliance stays local: Private regulation in the global electronics industry

Poor working conditions in global supply chains have led to private initiatives that seek to regulate labor practices in developing countries. But how effective are these regulatory programs? We investigate the effects of transnational private regulation by studying Hewlett‐Packard's (HP) supplier responsibility program. Using analysis of factory audits, interviews with buyer and supplier management, and field research at production facilities across seven countries, we find that national context – not repeated audits, capability building, or supply chain power – is the key predictor of workplace compliance. Quantitative analysis shows that factories in China are markedly less compliant than those in countries with stronger civil society and regulatory institutions. Comparative field research then illustrates how these local institutions complement transnational private regulation. Although these findings imply limits to private regulation in institutionally poor settings, they also highlight opportunities for productive linkages between transnational actors and local state and society.     

Machiavelli’s Science of Statecraft: The Diplomacy and Politics of Disorder

This paper calls into question the extent to which ethical dualism, broadly conceived as raison d’ état, does justice to Machiavelli’s understanding and practice of the diplomatic arts. Arguments are advanced herein that Machiavelli did not so much abandon morality as he sought, through the examples of Rome and antiquity, to find a different remedy for the disorder and violence rampant in the Italy of his day. Machiavelli’s reports in the diplomatic service of Florence illustrate qualities and skills of the diplomat often at odds with the caricature of the immoral statesman.
