Geoengineering and global warming: a strategic perspective

If major emitters fail to mitigate global warming, they may have to resort to geoengineering techniques that deflect sunlight from planet Earth and remove carbon dioxide from the atmosphere. In this article, I develop a strategic theory of geoengineering. I emphasize two key features of geoengineering. First, whereas emissions reductions can be mandated now, geoengineering techniques are only available in the future. Second, major powers can unilaterally implement geoengineering projects that may hurt other countries. My game-theoretic analysis demonstrates that unilateral geoengineering presents a difficult governance problem if it produces negative externalities in foreign countries. Interestingly, countries may be tempted to reduce emissions now, so as to prevent a harmful geoengineering race in the future. The theoretical results can help scholars and policymakers understand the relationship between climate mitigation and geoengineering.     

Comparison of five DNA quantification methods

Six commercial preparations of human genomic DNA were quantified using five quantification methods: UV spectrometry, SYBR-Green dye staining, slot blot hybridization with the probe D17Z1, Quantifiler™ Human DNA Quantification kit and RB1 rt-PCR. All methods measured higher DNA concentrations than expected based on the information by the manufacturers. UV spectrometry, SYBR-Green dye staining, slot blot and RB1 rt-PCR gave 39, 27, 11 and 12%, respectively, higher concentrations than expected based on the manufacturers’ information. The DNA preparations were quantified using the Quantifiler™ Human DNA Quantification kit in two experiments. The measured DNA concentrations with Quantifiler were 125 and 160% higher than expected based on the manufacturers’ information. When the Quantifiler™ human DNA standard (Raji cell line) was replaced by the commercial human DNA preparation G147A (Promega) to generate the DNA standard curve in the Quantifiler™ Human DNA Quantification kit, the DNA quantification results of the human DNA preparations were 31% higher than expected based on the manufacturers’ information. The results indicate a calibration problem with the Quantifiler™ human DNA standard for its use with the Quantifiler™ Human DNA Quantification kit. The possible reasons for the problem are discussed and a solution is suggested. The results emphasise the need for standard reference DNA material and standard methods for DNA quantification.     

Democracy and Discourse in an Integrating Europe and a Globalising World

Globalisation and Europeanisation represent challenges not only to national economies and institutions but also to national legitimating discourses. This paper first outlines the theoretical requirements for such discourse, by considering it along two dimensions: ideational, which encompasses cognitive and normative functions, and interactive, which encompasses co-ordinative and communicative functions. The paper illustrates these through empirical discussions of the post-war construction of discourses in France, Britain and Germany. It then examines how the discourses have responded to the challenges to traditional conceptions of economic organisation, social welfare, and political democracy from European and globally-related economic and institutional changes. The paper concludes that while France remains in search of a legitimating discourse, Britain is in the process of renewing its Thatcherite discourse, and Germany is in the process of recasting its post-war liberal social-democratic discourse.     

Between pedagogy and practice: developing and delivering international justice coursework in North America

While the need for new and innovative international coursework in North America has been recognized, developments in North American Universities have been few. Building on Mathias Reimann’s (Penn State International Law Review 22:397–415 [23]) useful justification for a new basic course in international law, this paper provides a discussion of a new approach to international justice coursework. Based on the nascent ICC and the jurisprudential developments of past international tribunals, a discrete international legal order has emerged. This may provide an opportunity for a broader examination of international criminal justice drawn from disciplines such as history, sociology, psychology, and criminology. By offering practical classroom techniques to assist in the delivery of international justice coursework, this paper attempts to provoke debate and discussion about how international coursework ought to be designed and delivered to a wider audience of undergraduate students.     

Fiscal Decentralization and Intergovernmental Transfers in Less Developed Countries

This article addresses the issue of fiscal decentralizationin developing countries, and the use of intergovernmental transfersto achieve this objective. We find that developing countrieshave more centralized fiscal structures and argue that thisis consistent with the theory of fiscal federalism. Economicdevelopment, however, does push the advantage toward decentralization.We also show that developing countries use a wide variety oftransfer instruments to fund local governments, and that theseinstruments give the national government varying degrees ofcontrol over local government finances.     

Allocative or Distributive Aims of Income Taxation?

Relations of income tax legislation and economic development are traditional subjects of German public finance. Reginald Hansen's book (1996) on practical consequences of the “Methodenstreit” for income taxation is considered under three aspects: history of economic thought, tax-systems and aims of income taxation. The introduction is followed by four paragraphs: 1. Long-term views of income taxation, 2. Reginald Hansen's comments on income taxation in Germany, 3. From Schmoller and Wagner to the modern German type of income taxation, 4. “Ability to pay,” “Pay as you use” or what else? The article demonstrates progressive and restrictive results of the long-term view focusing on the evaluation of income taxation principles.     

Distribution of ethyl glucuronide in rib bone marrow, other tissues and body liquids as proof of alcohol consumption before death

Postmortem ethyl glucuronide (EtG) concentrations in rib bone marrow, liver, muscle, fat tissue, urine, blood and bile have been determined by LC-MS/MS. Samples have been taken from twelve corpses during autopsies. In nine corpses EtG could be detected, corresponding blood ethanol concentrations (BAC) were 0.04-0.37 g%. In three cases, no EtG was found; two of these cases showed postmortem BACs - possibly due to putrefaction - of 0.01 and 0.1g%. In rib bone marrow, which is easily accessible during autopsy, EtG concentrations (0.77-9.36 microg/g) have been lower than in blood (2.24-20.46 microg/mL) in eight of nine cases and comparable or higher than in muscle tissue. Therefore, rib bone marrow has been found suitable as matrix for EtG determination. The highest EtG concentrations have been found in urine in all but one case, where the resorption of ethanol had been incomplete. Second highest EtG concentrations have been detected in liver samples. In two cases with putrefaction, EtG could not be detected. In these cases, the detectable ethanol might have been produced partially or in total by postmortem fermentation. However, instability of EtG during putrefaction cannot be totally excluded which might result in a total loss of EtG.     

Two simultaneous suicidal gunshots to the head with robbed police guns

The suicidal infliction of two gunshot wounds to the head represents a critical issue for medicolegal investigation. In principle, simultaneous infliction with two firearms or third parties' involvement, i.e. two consecutive gunshots, have to be considered. We report for the first time on a case of suicidal infliction of two simultaneous gunshots to the head (oral, temporal) with Action 4 expanding ammunition. A male had robbed two service guns and committed suicide thereafter under the influence of high-dose alcohol and cocaine. Interestingly, Action 4 ammunition had been used, leading to an uncommon gunshot wound morphology and extensive backspatter. At the scene, these findings caused confusion; moreover, the number of gunshot wounds was unclear, until autopsy revealed two gunshot wounds to the head, which had obviously been inflicted simultaneously. Expanding ammunition like QD-PEP and Action 4, used by several German federal state police forces, can cause an atypical gunshot wound morphology, most probably due to its peculiar deformation behaviour. Investigators should be careful when interpreting gunshot wound morphology at the scene after usage of such expanding ammunition. With regard to reconstruction in cases of two gunshot wounds to the head and two guns at the scene, two simultaneous gunshots should be taken into consideration.
