Headscarves,Judicial Activism,and Democracy: The 2007–8 Constitutional Crisis in Turkey

How are we to understand and analyse the constitutional tension in Turkey between the judiciary and the political sphere? In this article the issue is mirrored in the political crisis which started in April 2007 with the nomination of Abdullah Gül as presidential candidate by the moderate Islamist Justice and Development Party (AKP). The more detailed empirical background consists primarily of the dress code problematics including the matter of party closure. Theoretically, the “hegemonic preservation” thesis elaborated by Ran Hirschl turned out to be a useful instrument when it comes to explaining this political crisis as well as the origin of the so-called new constitutionalism. This is illustrated by the judicial activism in the headscarf affair as well as by the eagerness of the Republican People's Party (CHP), as the political representative of the secular establishment, to play the ‘Atatürk card’ and to submit the protection of their interest to an independent judiciary and not to the uncertainties of the mechanisms of majoritarian democracy. However, with regard to the current Turkish case my analysis also shows that Hirschl's thesis is too static and should be complemented with a more dynamic perspective of constitutional politics as a repeated game. One example of this is that even if the Turkish Constitutional Court (TCC) had declared the constitutional amendment on the headscarf invalid and voted for economic sanctions against the AKP, it did not close the party down.     

3D numerical modeling of hydrothermal processes during the lifetime of a deep geothermal reservoir

Understanding hydrothermal processes during production is critical to optimal geothermal reservoir management and sustainable utilization. This study addresses the hydrothermal (HT) processes in a geothermal research doublet consisting of the injection well E GrSk3/90 and production well Gt GrSk4/05 at the deep geothermal reservoir of Groß Schönebeck (north of Berlin, Germany) during geothermal power production. The reservoir is located between ?4050 to ?4250 m depth in the Lower Permian of the Northeast German Basin. Operational activities such as hydraulic stimulation, production (T = 150°C; Q = ?75 m³ h^?1; C = 265 g l^?1) and injection (T = 70°C; Q = 75 m³ h^?1; C = 265 g l^?1) change the HT conditions of the geothermal reservoir. The most significant changes affect temperature, mass concentration and pore pressure. These changes influence fluid density and viscosity as well as rock properties such as porosity, permeability, thermal conductivity and heat capacity. In addition, the geometry and hydraulic properties of hydraulically induced fractures vary during the lifetime of the reservoir. A three‐dimensional reservoir model was developed based on a structural geological model to simulate and understand the complex interaction of such processes. This model includes a full HT coupling of various petrophysical parameters. Specifically, temperature‐dependent thermal conductivity and heat capacity as well as the pressure‐, temperature‐ and mass concentration‐dependent fluid density and viscosity are considered. These parameters were determined by laboratory and field experiments. The effective pressure dependence of matrix permeability is less than 2.3% at our reservoir conditions and therefore can be neglected. The results of a three‐dimensional thermohaline finite‐element simulation of the life cycle performance of this geothermal well doublet indicate the beginning of thermal breakthrough after 3.6 years of utilization. This result is crucial for optimizing reservoir management. Geofluids (2010) 10 , 406–421     

Fruit and seed biomineralization and its effect on preservation

Mineralised fruits and seeds are frequently found in archaeological sediments but their chemical nature has not been often examined. The nature and the origin of these archaeobotanical remains have to be investigated to understand their taphonomic history. Fruits or seeds can be mineralised not only by replacement mineralisation but also by biomineralisation during the plant life. The mineral components of three fossil fruits sampled on the Pleistocene site of Dmanisi were analysed and compared with their modern analogues. Analyses were carried out by means of an environmental scanning electron microscope, equipped with an energy dispersive X-ray device and by means of a Fourier transform infrared spectrometer. Biogenic carbonates and/or biogenic silica were identified in the fossil and modern fruits of some taxa. Comparison between fossil and modern specimens has shown that molecular reorganisation occurred in carbonate and in biogenic silica during fossilisation, through diagenetic processes. The resulting stable mineral structures confer an exceptional preservation to fruits in sediments. Taking into account these taphonomic specificities (transformation and differential preservation), the chronological and palaeoenvironmental aspects of the mineralised fruits are discussed.     

Exploring the Multiple Roles of Lund University in Strengthening Scania's Regional Innovation System: Towards Institutional Learning?

Universities are increasingly seen as potential contributors to regional innovative capacity by serving as local knowledge conduits, bringing global state-of-the-art science and technology into the region. In practice, however, more active university engagement with their regional innovation systems is not as straightforward as it may seem. The article uses examples from a successful case by which less successful regions could be inspired. Our analysis considers how various forms of technological learning intersecting within Lund University around three distinct sectoral engagement efforts have been built up and how this created new structural regional innovation capacity.     

Abortion law reforms in Colombia and Nicaragua: issue networks and opportunity contexts

This article analyses two instances of abortion law reform in Latin America. In 2006, after a decades-long impasse, the highly controversial issue of abortion came to dominate the political agenda when Colombia liberalized its abortion law and Nicaragua adopted a total ban on abortion. The article analyses the central actors in the reform processes, their strategies and the opportunity contexts. Drawing on Htun's (2003) framework, it examines why these processes concluded with opposing legislative outcomes. The authors argue for the need to understand the state as a non-unitary site of politics and policy, and for judicial processes to be seen as a key variable in facilitating gender policy reforms in Latin America. In addition, they argue that ‘windows of opportunity’ such as the timing of elections can be critically important in legislative change processes.     

Feminist Perspectives on the Internationalization of The State

Abstract: The state is often described in transition: public spaces are rearranged by private companies, national social welfare is being privatized to some extent, and supranational institutions have more influence on national policies. “A view from the kitchen” (Diane Elson) is helpful for understanding the changing dynamics of states and societies because different women are affected by these policies in different and often ambiguous ways: women of the globalized South migrate to the North, creating global care chains, while women in Western industrialized countries are confronted with changing welfare regimes, leaving mainly highly educated women to profit from this situation. This article contributes to feminist debates on economic globalization and state internationalization. Our feminist materialist perspective allows a critical view on dominance and power in “governance”. Thus, the article adds to feminist debates on globalization from the perspective of state transformation and to debates on governance from the perspective of state transformation grounded in gendered social relations.     

Rhetoric and Corpuscularism in Berkeley's Siris

Berkeley's Siris may be an unduly neglected treatise. Yet it reveals and confirms its author's philosophical ambitions and achievements. The greatest of them is his theory of causality. Berkeley tries to show that agents can influence the world by using ethereal corpuscles as their instruments. These particles are both material but also in some sense immaterial or occult because they both follow and do not follow the laws of nature. Siris is a rhetorical text which uses analogy, metaphor, paradox, and ambiguity to illuminate the reader. I argue that the universe in Siris is ambiguous with respect to its material and immaterial essence. The world is at the same time scientific and material and metaphysical and immaterial. Berkeley fights against scientific mechanistic materialism when he subordinates science to God's will. I try to clarify how ambiguity works for Berkeley the metaphysician in establishing the superiority of minds or agents over matter and mechamisms.     

U-Pb zircon age of the youngest magmatic activity in the High Tatra granites (Central Western Carpathians)

Detailed cathodoluminescence (CL) imaging of zircon crystals, coupled with Laser Ablation Multi-Collector Inductively Coupled Plasma Mass Spectrometry (LA-MC-ICP-MS) U-Pb zircon dating was used to develop new insights into the evolution of granitoids from the High Tatra Mountains. The zircon U-Pb results show two distinct age groups (350±5 Ma and 337±6 Ma) recorded from cores and rims domains, respectively. Obtained results point that the last magmatic activity in the Tatra granitoid intrusion occurred at ca. 330 Ma. The previously suggested age of 314 Ma reflects rather the hydrothermal activity and Pb-loss, coupled with post-magmatic shearing.
