A study to narrow down the time when a hyoid bone fracture was sustained

An unstable hyoid bone that can be loosely moved during autopsy is initial reason to suspect trauma to the neck. The question to be answered is whether the increased mobility is due to incomplete ossification of the hyoid, a postmortem injury (damage), or an ante-mortem injury, possibly related to the cause of death. This is the first study to systematically assess whether stereomicroscopic examinations and flat-panel CT-scans of isolated, unstable hyoid bones can add information to the macroscopic examination by helping to determine when the instability arose. Sixteen isolated hyoid bones (8 female, 8 male; 4-87 years-old) were examined after being macerated. Four of the hyoid bones were already classified as unstable during autopsy. Of the other 12, 7 were fractured immediately after autopsy before being macerated, and 5 were fractured after being macerated. There were, in total, six different diagnostic constellations. Stereo-microscopic examination did not yield additional information compared with the macroscopic examination. Flat-panel CT allowed distinction between an incomplete ossification of the hyoid and a fracture, but did not help in determining whether the fracture had been sustained peri- or postmortem.     

Ossification Degrees of Cranial Sutures Determined with Flat‐Panel Computed Tomography: Narrowing the Age Estimate with Extrema

Abstract: Since Broca’s time (1824–1880), ossification of the neurocranial sutures has been used as a characteristic of age. Current approaches include the visual macroscopic examination of ecto and endocranial sutures. The evaluation of the cross‐section of sutures usually necessitates the destruction of the neurocranium. In a nondestructive alternative approach that was tested within the context of the “Digital Forensic Osteology” project that ran in cooperation with the Virtopsy^®‐Project, it emerged that the resolution of conventional multi‐slice computed tomography data sets was not high enough to image sutures. Thus for the experiments presented here, the eXplore Locus Ultra flat‐panel computed tomography scanner from GE Healthcare was used. Calottes were scanned during autopsy and then immediately returned to the corpse. So far, the skullcaps of 221 individuals have been scanned. The cross‐sections of 14 suture segments could be assessed for seven previously defined stages of ossification. In a converse step, the 14 highest and lowest age estimate values corresponding to the individual stages of suture closure found were estimated for each calotte. The obtained ranges narrowing down the age estimate were evaluated with statistics. A mean value of 43.31 years for the range of narrowed age estimates shows that this method can be a useful aid in estimating age. The results of intra‐ and inter‐observer tests showed good overall agreement between the findings of three observers. This method is suitable for a nondestructive age estimation and can be used for the entire calotte.     

Do African Manufacturing Firms Learn from Exporting?

We use firm-level panel data for the manufacturing sector in four African countries to investigate whether exporting impacts on efficiency, and whether efficient firms self-select into the export market. Based on simultaneous estimation of a production function and an export regression, our preferred results indicate significant efficiency gains from exporting, which can be interpreted as learning by exporting. We show that modelling unobserved heterogeneity by a flexible approach is important for deriving this conclusion. A policy implication of our results is that Africa would gain from orientating its manufacturing sector towards exporting.     

The spatial division of labour in Nepal

This article examines how economic activity and market participation are distributed across space. Applying a nonparametric von Thünen model to Nepalese data, we uncover a strong spatial division of labour. Non-farm employment is concentrated in and around cities while agricultural wage employment dominates villages located further away. Vegetables are produced near urban centres; paddy and commercial crops are more important at intermediate distances. Isolated villages revert to self-subsistence. Findings are consistent with the von Thünen model of concentric specialisation, corrected to account for city size. Spatial division of labour is closely related to factor endowments and household characteristics, especially at the local level.     

It's economic size,stupid! How global advocacy mirrors state power

Numerous empirical studies suggest that global interest communities are heavily biased in favor of wealthier countries. This research note critically reviews these works suggesting that they (i) lack a benchmark to assess the biased nature of global interest communities and (ii) conflate the concepts of “wealth” (based on GDP per capita) and “economic power” (based on GDP) into one analytical category. As a corrective to these problems, we compare variation in global interest group mobilization across countries to the size of these countries' national economies. Relying on an original dataset mapping interest groups communities at the World Trade Organization (1997–2012) and the United Nations Climate Summits (1997–2011), we show that (i) global interest representation almost perfectly reflects differences in countries' relative economic power and (ii) contrary to the conventional wisdom, wealthier countries are, relative to their economic size, actually underrepresented in global interest communities.     

Philemon and Baucis Death? Two cases of double deaths of married couples

When two human corpses are found in temporal and locational context the assumption of a non-natural cause of death is close at hand. Suicide, extended suicide, homicide or accident (particularly with carbon monoxide) come to mind. When, however, a natural cause of death emerges for both after autopsy and further examinations, this provokes the question whether this incidence is coincidental. In our two presented cases, a married couple each was found dead together. In both cases, the wife needed nursing and was being cared for by a husband who died of cardiac disease shortly before the wife died. In one case, the wife died of acute uncompensated chronic congestive heart failure. In the other case, the cause of death of the wife was hypovolemic shock due to acute gastrointestinal bleeding from recurrent gastric mucosal erosion. It is to be discussed for both cases whether, given the pre-existing illness, the acute stress of the situation in view to the husbands' death may at least have favored the occurrence of death and may, thus, have led to the criminologically conspicuous situation of finding.     

How Can the European Union Contribute to a COP-6 Agreement? An Overview for Policy Makers

During the 6th Conference of Parties (COP-6) in The Hague, the Netherlands, November 2000, crucial progress on a number of outstanding issues related to the Kyoto Protocol will have to be made to open the way for its early ratification, if not to save it from complete failure. Given the present lack of internal US political support for the Kyoto Protocol, the EU may play a pivotal role in making the Kyoto Protocol agreement a reality even without initial ratification of the US, if its able to provide sufficient leadership. In this overview article we discuss the main issues under negotiation, the problems of finding agreement and opportunities for the EU to catalyse a compromise agreement at COP-6, building on key scientific papers as included in this issue and discussions at the European Forum on Integrated Environmental Assessment Climate Policy Workshop in Amsterdam. Key elements are the inclusion of sinks, the use of the Kyoto Protocol mechanisms as a supplement to domestic action and the international compliance system. Domestic implementation of climate policy is a major factor for the EU's credibility.     

The incentive effects of settlements under joint and several liability

Several recent articles have examined the effects of joint and several liability on settlement. But these settlement effects also have a significant impact on primary behavior. This paper will examine these effects under the most frequently analyzed paradigm of joint and several liability, in which plaintiff's probabilities of success against the defendants are perfectly correlated and any settlements are applied to future awards under a pro tanto set-off rule (i.e., the award is reduced by the amount of the settlement).Section I will present the basic model of settlement under joint and several liability. Section II will draw the implications of settlement on primary behavior. As others have noted, the settlement effects of joint and several liability increase the expected recovery to the plaintiff and the expected damages payable by defendants. However, this does not mean that they increase defendants' incentives to take care ex ante. Rather, as I will show, the settlement effects of joint and several liability can either increase or decrease incentives to exercise care, depending on the nature of the uncertainty regarding defendant's liability and on the level of care that would prevail otherwise.
