During the past decade, processes associated with what is popularly though perhaps misleadingly known as globalization have come within the purview of anthropology. Migration and mobility ‐ and the footloose or even rootless social groups that they produce ‐ as well as the worldwide diffusion of commodities, media images, political ideas and practices, technologies and scientific knowledge today are on anthropology's research agenda. As a consequence, received notions about the ways in which culture relates to territory have been abandoned. The term transnationalisation captures cultural processes that stream across the borders of nation states. Anthropologists have been forced to revise the notion that transnationalisation would inevitably bring about a culturally homogenized world. Instead, we are witnessing a surge of greatly increasing cultural diversity. New cultural forms grow out of historically situated articulations of the local and the global. Rather than left-over relics from traditional orders, these are decidedly modern, yet far from uniform. The essay engages the idea of the pluralization of modernities, explores its potential for interdisciplinary research agendas, and also inquires into problematic assumptions underlying this new theoretical concept.
As of today, estimating interest rate reaction functions for the Euro Area is hampered by the short time span since the conduct of a single monetary policy. In this paper we circumvent the common use of aggregated data before 1999 by estimating interest rate reaction functions based on a panel including actual EMU Member States. We find that exploiting the cross-section dimen- sion of a multi-country panel and accounting for cross-country heterogeneity in advance of the single monetary policy pays off with regard to the estimated reaction functions' ability to describe actual interest rate dynamics. We retrieve a panel reaction function which is demonstrated to be a valuable tool for evaluating episodes of monetary policy since 1999. JEL - Klassifikation: E43 , E58 , C33
This paper employs individual bidding data to analyze the empirical performance of the longer term refinancing operations (LTROs) of the European Central Bank (ECB). We investigate how banks’ bidding behavior is related to a series of exogenous variables such as collateral costs, interest rate expectations, market volatility and to individual bank characteristics like country of origin, size, and experience. Panel regressions reveal that a bank’s bidding depends on bank characteristics. Yet, different bidding behavior generally does not translate into differences concerning bidder success. In contrast to the ECB’s main refinancing operations, we find evidence for the winner’s curse effect in LTROs. Our results indicate that LTROs do neither lead to market distortions nor to unfair auction outcomes. JEL classification: E52, D44
Even though tourism has been recognised as an important field for transnational research today, there are few attempts to place tourism in the context of transnational theories or to think about transnationalism from the perspective of tourists. I argue that in researching tourist practices one can add important aspects to transnational approaches. The prerequisites of mobility and interaction for example are the features chosen by backpackers to describe what their Round-The-World-Trip is about. A form of tourism is adopted, or created, that itself confronts many aspects of globalisation: First of all there is the immense dynamic that is involved. Backpackers try to cover as many places and experiences as possible, travelling at high speed. They adopt all kinds of touristic experiences ranging from beach to adventure to culture tourism. They don't focus on a specific area or country but travel the world. They cross national borders perpetually. Additionally they form a transnational network in which they interact with strangers of similar backgrounds (other backpackers, tourist professionals). This network helps them interacting with people from different backgrounds (the socalled hosts or locals). Considering my research Backpackers forge a certain identity from these transnational practices which I want to name globedentity. Globedentity expresses a type of identity construction that not only refers to the individual (I) but reflects the world (globe) in this identity. This globedentity is not fixed but is perpetually re-created and re-defined. It also embraces the increasing popular awareness of globalisation which backpackers, coming from highly educated middle class backgrounds, in particular have identified with. Due to the constant awareness of the latest global social, cultural and economic developments in these educated milieus they know exactly which tools to use to become successful parts of their societies.
I analysed the importance of shell size, shell shape, habitat preferences and availability, experienced climate, active dispersal and influence of Pleistocene glaciations for the range sizes of 37 Western Palaearctic Helicidae s.l. species for which a phylogeny was available. In both cross-species and phylogenetically controlled analyses, the range sizes were positively correlated to climatic tolerance, shell size, active dispersal and influence of Pleistocene glaciations. In addition, range sizes increased significantly with latitude. Multiple regression suggested that, predominantly, the influence of Pleistocene glaciations, tolerance to large annual temperature ranges and shell size influenced the distributional range sizes. Habitat preference, range and availability, active dispersal and shell shape explained no additional variance. The results suggest that the processes influencing species range size of the Helicidae s.l. are mainly related to the climatic shifts after the Pleistocene.
FGF-2, a potent multifunctional and neurotrophic growth factor, is widely expressed in the brain and upregulated in cerebral ischemia. Previous studies have shown that intraventricularly or systemically administered FGF-2 reduces the size of cerebral infarcts. Whether endogenous FGF-2 is beneficial for the outcome of cerebral ischemia has not been investigated. We have used mice with a null mutation of the fgf2 gene to explore the relevance of endogenous FGF-2 in brain ischemia. Focal cerebral ischemia was produced by occlusion of the middle cerebral artery (MCAO). We found a 75% increase in infarct volume in fgf2 knock-out mice versus wild type littermates (P < 0.05). This difference in the extent of ischemic damage was observed after 24 h, and correlated with decreased viability in fgf2 mutant mice following MCA occlusion. Increased infarct volume in fgf2 null mice was associated with a loss of induction in hippocampal BDNF and trkB mRNA expression. These findings indicate that signaling through trkB may contribute to ameliorating brain damage following ischemia and that bdnf and trkB may be target genes of FGF-2. Together, our data provide the first evidence that endogenous FGF-2 is important in coping with ischemic brain damage suggesting fgf2 as one crucial target gene for new therapeutic strategies in brain ischemia.
Taxation and tax policy reform appears on the political agenda in most advanced welfare states in Europe and North America. Of course studies of taxation and tax policy are nothing new and have existed ever since people have paid taxes. The current work is situated in the context of the future of the welfare state and the reinforced international economic and political integration referred to as "globalization." The purpose of this paper is to analyze how globalization is affecting tax policy in advanced welfare states. In comparing the evolution of tax policy in Canada with those in the United States, Germany and Sweden from 1960 to 1995, I will try to review the conventional antiglobalization thesis, i.e., that globalization leads to a "race to the bottom" in revenue and expenditures policies, or as others have called it, a "beggar the neighbour policy" (Tanzi and Bovenberg 1990, 187). ... Conclusion: The empirical data and theoretical models clearly show that globalization is one relatively minor factor among many that explain tax policy reforms. And even that limited influence is mediated by domestic political systems, institutions and constellations of actors. As the data has shown, the conventional globalization thesis of a race to the bottom is not borne out. Tax rates and tax revenues are still increasing, despite the ongoing trend toward international trade integration. Countervailing pressures like the high cost of welfare programs, different parties in government, strong labour unions, and institutional veto players counteract the pressure of globalization on tax policy. As for the future of taxation in Canada, it is more likely to be one of gradual evolution than radical change. Although the data don’t show any downward pressure on tax rates and tax revenues comparatively speaking, there are at least four key factors in Canada that are likely to put pressure on future tax rates, although regional political dynamics and the workings of fiscal federalism suggest that tax reductions will be a higher priority in some provinces than others (Hale 2002). First, neoliberalism will continue to shape fiscal and tax policy, including the role of the tax system in delivering social policies and programs in most parts of Canada. Second, governments that seek to define their own economic and social priorities rather than simply react to events beyond their borders will have to exercise centralized control over budgetary policies and spending levels if they hope to foster the economic growth needed to finance social services in the context of Canada’s changing demographics. Third, the ability of governments to combine the promotion of economic growth and higher living standards will be closely linked to their ability to develop a workable division of responsibilities among federal and provincial governments and with other national governments. Finally, the diffusion of new technologies will continue to transform national and regional economies while giving individuals greater opportunity to avoid government and tax regulations that run contrary to their perceived interests and values. This discussion of determinants that shape tax policy reform has shown that successful management of fiscal and tax policy requires a capacity to set priorities; adapt to changing circumstances; and build a consensus that enables competing economic, social, regional and ideological interests to identify their own well-being in the broader political and economic environment. Tax policy is shaped by many political, economic and social determinants. As Geoffrey Hale correctly concludes, "it should not be surprising if the tax system stubbornly refuses to confirm either economic theories or political ideologies, but reflects past decisions and the policy tradeoffs of the political process" (2002, 71). The notion of tax policy being driven by globalization and forces associated with globalization (both positive and negative) is simply not borne by the facts.
Despite a legal framework being in place for several years, the market share of qualified electronic signatures is disappointingly low. Mobile Signatures provide a new and promising opportunity for the deployment of an infrastructure for qualified electronic signatures. We that SIM-based signatures are the most secure and convenient solution. However, using the SIM-card as a secure signature creation device (SSCD) raises new challenges, because it would contain the user’s private key as well as the subscriber identification. Combining both functions in one card raises the question who will have the control over the keys and certificates. We propose a protocol called Certification on Demand (COD) that separates certification services from subscriber identification information and allows consumers to choose their appropriate certification services and service providers based on their needs. This infrastructure could be used to enable secure mobile brokerage services that can ommit the necessity of TAN lists and therefore allow a better integration of information and transaction services.
Chemically modified bases are frequently used to stabilize nucleic acids, to study the driving forces for nucleic acid structure formation and to tune DNA and RNA hybridization conditions. In particular, fluorobenzene and fluorobenzimidazole base analogues can act as universal bases able to pair with any natural base and to stabilize RNA duplex formation. Although these base analogues are compatible with an A-form RNA geometry, little is known about the influence on the fine structure and conformational dynamics of RNA. In the present study, nano-second molecular dynamics (MD) simulations have been performed to characterize the dynamics of RNA duplexes containing a central 1'-deoxy-1'-(2,4-difluorophenyl)-ß-D-ribofuranose base pair or opposite to an adenine base. For comparison, RNA with a central uridine:adenine pair and a 1'-deoxy-1'-(phenyl)-ß-D-ribofuranose opposite to an adenine was also investigated. The MD simulations indicate a stable overall A-form geometry for the RNAs with base analogues. However, the presence of the base analogues caused a locally enhanced mobility of the central bases inducing mainly base pair shear and opening motions. No stable ‘base-paired’ geometry was found for the base analogue pair or the base analogue:adenine pairs, which explains in part the universal base character of these analogues. Instead, the conformational fluctuations of the base analogues lead to an enhanced accessibility of the bases in the major and minor grooves of the helix compared with a regular base pair.
RDF is widely used in order to catalogue the chaos of data across the internet. But these descriptions must be stored, evaluated, analyzed and verified. This creates the need to search for an environment to realize these aspects and strengthen RDFs influence. InterSystems postrelational database Caché exposes many features that are similar to RDF and provide persistence with semantic part. Some models for relational databases exist but these lack features like object-oriented data-structures and multidimensional variables. The aim of this thesis is to develop an RDF model for Caché that saves RDF data in an object-oriented form. Furthermore an interface for importing RDF data will be presented and implemented.
