A discriminant function analysis of deciduous teeth to determine sex

Studies of deciduous teeth have concluded that crown size differences in these teeth between males and females are not reliable sex discriminators, in contrast to such differences in permanent teeth. This study measured the mesiodistal and faciolingual crown diameters of all deciduous teeth, as well as those of the permanent first molars, of 162 children from the Burlington Orthodontic Growth Study, conducted earlier in Burlington, Ontario, Canada. All 40 deciduous tooth diameters (20 mesiolingual and 20 faciolingual) were significantly different between the sexes, as were the permanent tooth diameters. Using three to five measurements of deciduous teeth, discriminant analyses of several samplings of these children produced discriminant functions in which 76 to 90% of the holdout samples were correctly classified by sex. Combinations of deciduous and permanent measurements were used to classify 83 to 85% of the holdout samples correctly. When compared with published data on other sample populations, the Burlington group is the most dimorphic for deciduous teeth and is within the range of permanent tooth dimorphisms of other populations. The level of classification accuracy, when using discriminant analysis of the deciduous teeth, can approach the accuracy levels of analysis using the permanent teeth.     

Is informalization equalizing? Evidence from Kinshasa (DRC)

As a consequence of a concatenation of external and internal events, the economy of the Democratic Republic of the Congo (DRC) has informalized to an unprecedented level over the last few decades. A comparison of budget surveys carried out in 1975 and 2004 respectively allows us to ascertain the effect of this process on income inequality and poverty in Kinshasa. We find that the extent of inequality in the capital city of the DRC has remained largely unchanged, which strongly suggests that informalization has been a viable survival strategy for those at the lower-income end of society. Unexpectedly, whereas distinctions such as gender and age lost much of their profiling power in the period considered, other cleavages such as education and geography, which may be assumed to be much more intimately related to the formal sector, continued to play an important role in structuring inequality in Kinshasa’s deeply informalized economy.     

The pre-employment inquiry guide

In recent years, government regulation of both EEO and affirmative action has grown rapidly. As a result, the road to hiring an employee is strewn with pitfalls for the unaware and the uninitiated. This practical guide, written for the practicing personnel manager, takes account of the latest government directives in the field and should prove a valuable tool for anyone involved in the business of hiring.     

A Search for Truth: A Critical Analysis of the Liberian Truth and Reconciliation Commission

In Liberia, much debate has surrounded the truth and reconciliation commission both in the challenges that it faced during its operational stage as well as in the issues surrounding the release and content of its report. This article will critically examine the establishment, proceedings, and findings of the Liberian Truth and Reconciliation Commission in order to draw conclusions regarding what lessons can be learned, what could have been done to make the commission more effective, and how we can learn from this example in applying transitional justice mechanisms for future African conflicts.     

Steuerung jenseits von Hierarchie

The paper sheds new light on recent debates about governance and approaches contemporary problems of governing from the perspective of contemporary theories of power. The concept of “soft governing” is developed in order to capture horizontal mechanisms of power intentionally used to govern beyond formalised hierarchies characteristic of processes of governance. The paper describes in particular the horizontal forms of governing through discursive practices, argumentation and symbols and the ways in which they interact. The example of campaigns against female genital mutilation is introduced in order to illustrate possible forms of governing beyond hierarchy.     

The scientific foundation of dynamic stochastic general equilibrium (DSGE) models

DSGE-models provide a coherent framework of analysis. This coherence is brought about by restricting acceptable behavior of agents to dynamic utility maximization and rational expectations. The problem of the DSGE-models (and more generally of macroeconomic models based on rational expectations) is that they assume extraordinary cognitive capabilities of individual agents. In addition, these models need a lot of ad-hoc assumptions to make them fit the data. I argue that we need models that take into account the limited cognitive abilities of agents. One can introduce rationality in such models by assuming “trial and error“ learning. I propose such a model and I analyze its implications.     

The Unintended Consequences of the Transatlantic Trade and Investment Partnership Negotiations

ABSTRACT

Although stalled since 2016, the negotiations on a Transatlantic Trade and Investment Partnership (TTIP) have had major unintended consequences. The TTIP led to demands from third countries to upgrade their trade relationship with the EU and to unprecedented politicisation. As second-order effects of the latter, it endangered the EU-Canada trade agreement and brought about reform of EU trade governance and amendments to EU trade policy positions. These unintended consequences occurred because of inflated expectations about and insufficient awareness of the different nature of TTIP with regard to scope and partner compared to other trade negotiations. In the meantime, EU trade policy has adapted to the new politics of trade, making unintended consequences less likely.
