Aid and Trade – A Donor's Perspective

One reason donors provide foreign aid is to support their exports to aid-recipient countries. Time series data for Germany suggests an average return of between US$1.04–$1.50 for each US dollar of aid spent by Germany. Although this is well below previous estimates, the value is robust to different specifications and econometric approaches. Interestingly, we find strong evidence of crowding out between bilateral donors in the sense that bilateral aid from other EU members significantly reduces exports from Germany to the recipients. The evidence suggests that, in the long run, aid causes exports and not vice versa. We discuss the implications these findings might have for aid volumes and allocation.     

Die elementaren (Fremd-)Erfahrungen der Gabe

What holds society together? In his famous essay The Gift (1925) Marcel Mauss answers this question. However, as this paper shows, he does so not by formulating something like a theory of reciprocity as was often assumed after Claude Lévi-Strauss’ brought forward his structuralist interpretation of Mauss. Instead, the reason why gift practices create obligatory, cohesive social bonds lies in experiences of ?being-possessed“ and self-transcendence. This assumption is proven by means of a new and detailed reading of Mauss’ Essai sur le don as well as by the anti-utilitarian reception of Mauss’ work by the Collège de Sociologie (Georges Bataille, Roger Caillois, Michel Leiris). Overall, Mauss’ theory of the gift features important elements of a theory of posession and self-transcendence which focuses on the dimensions of experience and action. This is why one can discern a certain similarity between Mauss’ and the pragmatist theory of action. Only against that backdrop the social binding force of gift practices can be explained.     

Further Evidence on the Anatomical Placement of the Human Eyeball for Facial Approximation and Craniofacial Superimposition*

Abstract: Recently a small sampled cadaver study (n = 4) suggested that the human eyeballs are placed closer to the orbital roof and lateral orbital wall as first reported in the anatomical literature many years previously. This contrasts with central positioning of the eyeball within the orbit as advocated by the facial approximation literature. Given the limits of such small samples, this study re-examined globe position in nine new cadavers to help clarify which relationship is accurate. The results essentially confirm prior empirical findings except that the mean lateral divergences from the orbit center were found to be larger—the eyeball was found to be “displaced” 1.4 mm superiorly and 2.4 mm laterally. Medians calculated across all 13 cadavers from this study and the above-mentioned recent report refine these measurements to 1.4 and 2.3 mm respectively. Globe projection values were identical to those observed for living individuals (c. 16 mm).     

PREDICTING STATE ABORTION LEGISLATION FROM U.S. SENATE VOTES: THE EFFECTS OF APPARENT IDEOLOGICAL SHIRKING

The recent Supreme Court decision in Webster v. Reproductive Health Services giving more discretion to states to regulate abortion has led to speculation concerning which states might move to limit abortions. Medoff (1989) attempts to predict how state legislatures might vote on state-level abortion legislation by examining the 1983 Senate vote on the Hatch/Eagleton Amendment. We expand upon Medoff's analysis by incor- porating recent developments in agency theory as it applies to the political agents (i.e., Senators) in the empirical model. The results demonstrate that accounting for Senatorial "shirking" and state ideology substantially im- proves the predictive ability of the model for the Senate abortion vote. The predicted votes of the state's Senators, after eliminating the effects of apparent Senatorial shirking, are used to infer the likelihood of state-level legislation substantially restricting abortion. We compare these results to a base model that ignores the issue of shirking and find increased predict- ability and several differing results.     

Facial approximation: globe projection guideline falsified by exophthalmometry literature

The projection of the cornea from the bony orbit has been determined, in facial approximation, by centrally locating the eyeball in the orbit and positioning the cornea so that its most anterior point falls in line with a tangent dropped from the mid-superior to the mid-inferior orbital rim. However, there appears to be no scientific evidence to justify this guideline; yet, there have been numerous studies that measure globe projection in living subjects, from the lateral orbit using an exophthalmometer. The aim of this study was to determine if the traditional facial approximation guideline is consistent with the exophthalmometry literature. MRI research shows that corneal projection is underestimated using the traditional facial approximation guideline. An underestimation is also strongly supported by statistical comparisons of globe projection measures taken using more traditional instruments (e.g., Hertel's exophthalmometer) to skull morphology (p < 0.006). It is suggested that the traditional facial approximation guideline not be used in future facial approximations since it appears to under-predict anterior globe projection by 4 mm on average. It is also suggested that average exophthalmometer values be used until more accurate and precise ways of determining globe projection have been determined.     

Do resemblance ratings measure the accuracy of facial approximations?

Since forensic facial approximations are used to promote recognition of a deceased person, an accurate forensic facial approximation (FFA) should be easily recognized as the person to whom the skull belonged (target individual). However, the accuracy of FFAs has been previously assessed by the direct comparison of an FFA to the corresponding target individual for similarity (i.e., a resemblance rating). Resemblance ratings may not indicate a facial approximation's accuracy since the resemblance of non-target individuals is not accounted for. This experiment tests the validity of using resemblance ratings to assess the accuracy of FFAs. The study indicates that there is no statistically significant difference between: (a) resemblance ratings of FFAs to target individuals and (b) resemblance ratings of FFAs to individuals incorrectly identified as the target individual. It is concluded that it is not possible from resemblance ratings to determine the accuracy and/or quality of a facial approximation since a non-target individual may receive a resemblance rating equal to, or higher than, the target individual.
