The behavioural consequences of institutional rules: republicans in the US house

The Republicans gained a majority in the US House from the 1994 elections, and upon taking office they rewrote the rules that determine legislative power relations. This paper combines a 1996 attitudinal survey of US Representatives with demographic information, status within the House, and party position to examine the impact of the 1995 rule changes on satisfaction, ambition, and retirement. This paper demonstrates that member reactions to reform are explained jointly by their partisanship and their relative position within their party. Senior members of any party dislike rules making power more exclusive, and dissatisfaction increases the likelihood of retirement.     

EU Merger Control: From Separate Jurisdictional Zones to a More Cooperative Architecture—A Possible Way Forward?

The paper is a call to re-ignite the debate over the future shape of the EU’s concentration or merger control architecture in the longer-term. The paper contributes to this debate by considering the efficacy of replacing the current merger control architecture of separate jurisdictional zones with a more cooperative approach. It demonstrates that the adoption of the cooperative architecture would result in a number of benefits relative to the operation of the current architecture. For in effectively resolving a major problem that has dogged the operational effectiveness of the current architecture since it became law in 1990, the misallocation problem, the proposed architecture would also lead to a strengthening of the application of the principle of subsidiarity in this field, be supportive of the reinterpreted more appropriate authority goal, and resolve the multiple notification issue. Further, by ending the multiple notification issue, the valued one-stop shop approach to merger regulation would be reinforced. Yet the paper recognises that the cooperative architecture itself is not concern free, for the cooperative approach in granting Member state regulators the right for the first time to apply EU merger law, albeit in certain circumstances only, creates the possibility of inconsistent decision-making across this network. This would distort the regulatory level playing field, undermining what the architecture is supposed to guarantee, the Single European Market. With this in mind, necessary safeguards are explained. The paper concludes by briefly commenting upon key systems that need to be in place to ensure the operational effectiveness of the cooperative architecture. Of course, and at the cost of stating the obvious, improving the protection of competition in the field of merger control in the longer-term requires a willingness on the part of the key stakeholders to look beyond the current architecture of separate jurisdictional zones.     

The GE/Honeywell merger controversy and the path to analytical convergence in international merger assessment: A critical commentary

Globalisation, with its concomitant rise in international merger activity, allied to the proliferation of merger control regimes vetting such activity, increases the likelihood of two or more competition authorities reaching divergent decisions in the same case. This article reveals that this situation arose in the proposed merger between two US-based companies, General Electric (GE) and Honeywell, with the EU prohibiting the merger, and the US Department of Justice approving it. Further, it discusses the analytical and interpretational differences which led to those divergent outcomes. The analytical debate centres on the appropriateness of the two theoretical approaches used to assess proposed mergers, with the EU using the range effects of competitive harm approach and the US giving greater weight to an economic efficiencies merger defence. The fallout from the GE/Honeywell case has given added impetus to progress analytical convergence in relation to the vetting of international mergers. This has found expression at the multilateral level, which links to EU initiatives. The article predicts that the EU is highly likely to incorporate an economic efficiencies defence into its merger control law, bringing it into line with other key players. Of course, analytical convergence cannot guarantee that interpretational differences will not arise, as was evident in aspects of the GE/Honeywell case.

A longitudinal study of moral and ego development in young adults

The purpose of this study was to investigate the longitudinal changes in moral judgment and ego development in a young adult sample when a concurrent measure of verbal ability was used as a statistical control. Sixty-one late adolescents and young adults, representing three educational groups, were tested in 1977 and 1979 on the Defining Issues Tests, a measure of moral judgment (Rest), the Sentence Completion Test of Ego Development (Loevinger and Wessler) and Terman's Concept Mastery Test, a measure of verbal ability. No group or time differences were found in ego development. A significant increase was found between the 1977 and 1979 moral judgment scores,p<0.05, and between groups at both testing,p<0.001. Sex differences were found,p<0.01, with females scoring higher than males, which were statistically accounted for by verbal ability. These findings suggest that moral development continues into the young adult years and that verbal ability may moderate sex differences in moral judgment.     

The evaluation of evidence in the forensic investigation of fire incidents (Part I): an approach using Bayesian networks

The forensic investigation of the origin and cause of a fire incident is a particularly demanding area of expertise. As the available evidence is often incomplete or vague, uncertainty is a key element. The present study is an attempt to approach this through the use of Bayesian networks, which have been found useful in assisting human reasoning in a variety of disciplines in which uncertainty plays a central role. The present paper describes the construction of a Bayesian network (BN) and its use for drawing inferences about propositions of interest, based upon a single, possibly non replicable item of evidence: detected residual quantities of a flammable liquid in fire debris.     

Nine-locus Y-chromosome STR profiling of Caucasian and Xhosa populations from Cape Town, South Africa

Y-chromosome STR markers are not widely used in forensic case work in South Africa. To begin assessing the forensic value of these markers in South Africa, samples were collected from 100 English-speaking Caucasian males and 99 Xhosa males, living in the Cape Town metropolitan area. Allele and haplotype frequencies were determined for nine Y-chromosome STR loci (DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, and the duplicated locus DYS385). Unique haplotypes were obtained for 47 Xhosa males and 66 Caucasians.
