The Legal Protection of Fundamental Human Values in Central and Eastern Europe and Modern Biotechnology: Towards European Harmonization

The protection of the fundamental human values (life, bodily integrity, human dignity, privacy) becomes imperative with the rapid progress in modern biotechnology, which can result in major alterations in the genetic make-up of organisms. It has become possible to insert human genes into pigs so that their internal organs coated in human proteins are more suitable for transplantation into humans (xenotransplantation), and micro-organisms that cam make insulin have been created, thus changing the genetic make-up of humans. At the end of the 1980s, the Central and Eastern European (CEE) countries either initiated new legislation or started to amend existing laws in this area (clinical testing of drugs, experiments on man, prenatal genetic diagnosis, legal protection of the embryo/foetus, etc.). The analysis here indicates that the CEE countries have not sufficiently adjusted their regulations to the findings of modern biotechnology, either because of the relatively short period they have had to do so, or because there are no definite answers to the questions which modern biotechnology has raised (ethical aspects of xenotransplantation, or of the use of live-aborted embryonic or foetal tissue in neuro-transplantation, etc.). In order to harmonise the existing regulations in CEE countries with respect to the EU and supranational contexts, two critical issues should be taken into consideration. The first is the necessity for CEE countries to recognise the place of humans within the achievements of modern biotechnology (a broader affirmation of the principle of autonomy, an explicit ban on the violation of the genetic identity of either born or unborn life, etc.). The second concerns the definition of the status of different biotechnological procedures and their permissibility (gene therapy, therapeutic genomes, xenotransplantation, etc.). The road towards such answers may be more easily identified once all CEE countries become members of the Council of Europe and express their wish to join the EU, which in turn presupposes taking over the entire body of EU legislation.

Glacier mass balance reconstruction by sublimation induced enrichment of chemical species on Cerro Tapado (Chilean Andes)

A 36 m long ice core down to bedrock from the Cerro Tapado glacier (5536 m a.s.l, 30°08' S, 69°55' W) was analyzed to reconstruct past climatic conditions for Northern Chile. Because of the marked seasonality in the precipitation (short wet winter and extended dry summer periods) in this region, major snow ablation and related post-depositional processes occur on the glacier surface during summer periods. They include predominantly sublimation and dry deposition. Assuming that, like measured during the field campaign, the enrichment of chloride was always related to sublimation, the chemical record along the ice core may be applied to reconstruct the history of such secondary processes linked to the past climatic conditions over northern Chile. For the time period 1962–1999, a mean annual net accumulation of 316 mm water equivalent (weq) and 327 mm weq loss by sublimation was deduced by this method. This corresponds to an initial total annual accumulation of 539 mm weq. The annual variability of the accumulation and sublimation is related with the Southern Oscillation Index (SOI): higher net-accumulation during El-Niño years and more sublimation during La Niña years. The deepest part of the ice record shows a time discontinuity; with an ice body deposited under different climatic conditions: 290 mm higher precipitation but with reduced seasonal distribution (+470 mm in winter and –180 mm in summer) and –3°C lower mean annual temperature. Unfortunately, its age is unknown. The comparison with regional proxy data however let us conclude that the glacier buildup did most likely occur after the dry mid-Holocene.

IMPACT OF ENGINE CALIBRATION ON PM OXIDATION IN A CATALYZED PARTICULATE FILTER OVER A TRANSIENT CYCLE: A MODELLING STUDY

The combustion strategy in a diesel engine has an impact on the emissions, fuel consumption and the exhaust temperatures. The PM mass retained in the CPF is a function of NO2 and PM concentrations in addition to the exhaust temperatures and the flow rates. Thus the engine combustion strategy affects exhaust characteristics which has an impact on the CPF operation and PM mass retained and oxidized. In this report, a process has been developed to simulate the relationship between engine calibration, performance and HC and PM oxidation in the DOC and CPF respectively. Fuel Rail Pressure (FRP) and Start of Injection (SOI) sweeps were carried out at five steady state engine operating conditions. This data, along with data from a previously carried out surrogate HD-FTP cycle [1], was used to create a transfer function model which estimates the engine out emissions, flow rates, temperatures for varied FRP and SOI over a transient cycle. Four different calibrations (test cases) were considered in this study, which were simulated through the transfer function model and the DOC model [1, 2]. The DOC outputs were then input into a model which simulates the NO2 assisted and thermal PM oxidation inside a CPF. Finally, results were analyzed as to how engine calibration impacts the engine fuel consumption, HC oxidation in the DOC and the PM oxidation in the CPF. Also, active regeneration for various test cases was simulated and a comparative analysis of the fuel penalties involved was carried out.

IMPROVING STARTABILITY AND REDUCING EMISSIONS IN FLEXFUEL SPARK IGNITION DIRECT INJECTION VARIABLE CAM TIMING ENGINE

Experimental work and analysis was done to investigate engine startup robustness and emissions of a flex-fuel spark ignition (SI) direct injection (DI) engine. The vaporization and other characteristics of ethanol fuel blends present a challenge at engine startup. Strategies to reduce the enrichment requirements for the first engine startup cycle and emissions for the second and third fired cycle at 25°C ± 1°C engine and intake air temperature were investigated. Research work was conducted on a single cylinder SIDI engine with gasoline and E85 fuels, to study the effect on first fired cycle of engine startup. Piston configurations that included a compression ratio change (11 vs 15.5) and piston geometry change (flattop vs bowl) were tested, along with changes in intake cam timing (95,110,125) and fuel pressure (0.4 MPa vs 3 MPa). The goal was to replicate the engine speed, manifold pressure, fuel pressure and testing temperature from an engine startup trace for investigating the first fired cycle for the engine. Results showed bowl piston was able to enable lower equivalence ratio engine starts with gasoline fuel, while also showing lower IMEP at the same equivalence ratio compared to flat top piston. With E85, bowl piston showed reduced IMEP as compression ratio increased at the same equivalence ratio. A preference for constant intake valve timing across fuels seemed to indicate that flattop piston might be a good flex-fuel piston. Significant improvements were seen with higher CR bowl piston with high fuel pressure starts, but showed no improvement with low fuel pressures. Simulation work was conducted to analyze initial three cycles of engine startup in GT-POWER for the same set of hardware used in the experimentations. A steady state validated model was modified for startup conditions. The results of which allowed an understanding of the relative residual levels and IMEP at the test points in the cam phasing space. This allowed selecting additional test points that enable use of higher residual levels, eliminating those with smaller trapped mass incapable of producing required IMEP for proper engine turnover. The second phase of experimental testing results for 2nd and 3rd startup cycle revealed both E10 and E85 prefer the same SOI of 240°bTDC at second and third startup cycle for the flat top piston and high injection pressures. E85 fuel optimal cam timing for startup showed that it tolerates more residuals compared to E10 fuel. Higher internal residuals drives down the Ø requirement for both fuels up to their combustion stability limit, this is thought to be direct benefit to vaporization due to increased cycle start temperature. Benefits are shown for an advance IMOP and retarded EMOP strategy at engine startup. Overall the amount of residuals preferred by an engine for E10 fuel at startup is thought to be constant across engine speed, thus could enable easier selection of optimized cam positions across the startup speeds.

Double Standards? Veils and Crucifixes in the European Legal Order

Comparing the treatment of Islamic veils and Christian crucifixes by the European Court of Human Rights, this paper re-examines the charge of “double standards” on the part of this guardian of the European legal order, which is seen as disadvantaging Islam and favoring Christianity. While this is proved partially correct, the paper calls for a more differentiated treatment of the issue. For one, there is a modicum of consistency in the European Court’s decisions, because they are all meant to further “pluralism”. Only, Islam and Christianity fare differently in this respect, as “threat” to and “affirmation” of pluralism, respectively. This distinction hinges on Islam’s compatibility with the liberal-secular order, on which the jury is out. A possible way out of the “pluralism v. pluralism” dilemma, I argue, is signaled in the European Court’s recent decision in Lautsi v. Italy (2011), which pairs a preference for “culturalized” Christianity with robust minority pluralism.

The Law of the WTO and the Communications Law of the EC : On a Path of Harmony or Discord?

This paper presents an overview of the law of the World Trade Organization (WTO) relevant to telecommunications services and correlates this body of law with the current regulatory framework for electronic communications networks and services in the European Community. The latter has been adapted to meet the challenges of technological and market developments in communications, epitomized by the processes of digitization, enhanced transport networks and convergence. The novel solutions embodied in the EC electronic communications regime, notably, a new design of the Significant Market Power mechanism, a projected withdrawal of sector specific regulation and an affirmation of the principle of technological neutrality, pose interesting questions as to the conformity of this reformed EC communications law with the WTO rules on telecommunications services and the obligations of the European Communities and their Member States. Looking beyond the WTO legal compatibility test, essential questions regarding the need for evolution of the WTO telecommunications rules are raised. The present paper contributes to the ongoing debate in that context in light of the EC experience.

Relations between adolescents' self-evaluations, time perspectives, motivation for school and their achievement in different countries and at different ages

The present study focused on the relations between the self-efficacy, social self-concept, time perspectives, school investment and academic achievement of students in four different European countries and in different adolescence periods. A total of 1623 students completed questionnaires. The relations between the concepts proved not to be specific to the Western or to the former Communist bloc countries studied. The expected general decline in investment and academic achievement over the adolescence period showed up in all four countries studied. Contrary to our hypothesis, however, this decline could not be explained by growing influences of either social self-concept or time perspectives regarding personal development on their investment. In fact, the effects of social self-concept were strongest for the youngest adolescence group. Students’ social self-concept was the best predictor for their investment, while self-efficacy proved to predict academic achievement best in all adolescence periods.

Climate Variability in West Antarctica Derived from Annual Accumulation-Rate Records from ITASE Firn/Ice Cores

Thirteen annually resolved accumulation-rate records covering the last similar to 200 years from the Pine Island-Thwaites and Ross drainage systems and the South Pole are used to examine climate variability over West Antarctica. Accumulation is controlled spatially by the topography of the ice sheet, and temporally by changes in moisture transport and cyclonic activity. A comparison of mean accumulation since 1970 at each site to the long-term mean indicates an increase in accumulation for sites located in the western sector of the Pine Island-Thwaites drainage system. Accumulation is negatively associated with the Southern Oscillation Index (Sol) for sites near the ice divide, and periods of sustained negative Sol (1940-42, 1991-95) correspond to above-mean accumulation at most sites. Correlations of the accumulation-rate records with sea-level pressure (SLP) and the SOI suggest that accumulation near the ice divide and in the Ross drainage system may be associated with the midlatitudes. The post-1970 increase in accumulation coupled with strong SLP-accumulation-rate correlations near the coast suggests recent intensification of cyclonic activity in the Pine Island-Thwaites drainage system.

The Effects of Joint ENSO-Antarctic Oscillation Forcing on the McMurdo Dry Valleys, Antarctica

Stable oxygen analyses and snow accumulation rates from snow pits sampled in the McMurdo Dry Valleys have been used to reconstruct variations in summer temperature and moisture availability over the last four decades. The temperature data show a common interannual variability, with strong regional warmings occurring especially in 1984/85, 1995/96 and 1990/91 and profound coolings during 1977/78, 1983/84, 1988/89, 1993/94, and 1996/97. Annual snow accumulation shows a larger variance between sites, but the early 1970s, 1984, 1997, and to a lesser degree 1990/91 are characterized overall by wetter conditions, while the early and late 1980s show low snow accumulation values. Comparison of the reconstructed and measured summer temperatures with the Southern Oscillation Index (SOI) and the Antarctic Oscillation (AAO) yield statistically significant correlations, which improve when phaserelationships are considered. A distinct change in the phase relationship of the correlation is observed, with the SOI-AAO leading over the temperature records by one year before, and lagging by one year after 1988. These results suggest that over the last two decades summer temperatures are influenced by opposing El Niho Southern Oscillation and AAO forcings and support previous studies that identified a change in the Tropical-Antarctic teleconnection between the 1980s and 1990s.

Michel Butor à la frontière

Dans l’œuvre de Michel Butor, la frontière peut être considérée comme un équivalent de la césure, comme le pli de la double page constituait un équivalent de la césure dans Un coup de dés chez Mallarmé. Elle se retrouve dans de très nombreuses œuvres, des romans au Génie du lieu, et dans de nombreuses œuvres poétiques, dont À la frontière et Frontières. Chez Butor, la frontière a un rôle d’articulateur ; mais cette articulation ne va pas de soi, et il faut passer par des «méditations» sur la frontière, qui permettent d’établir une typologie des diverses fonctions de la frontière.]
