The determinants and impact of foreign direct investment in Central and Eastern Europe: A comparison of survey and econometric evidence
This note considers evidence that has been collected on the determinants and effects of foreign direct investment in Central and Eastern Europe, with a strong focus on Hungary, Poland and the Czech Republic. There are two main sources from which information is drawn: survey studies and econometric studies. We consider how each of these sources can contribute to research, whether they provide complementary or contradictory information, and how the information can be best exploited. We conclude that the findings of econometric studies tend to support survey results. This suggests that market size and growth potential have been the driving forces behind foreign direct investment, with factor-cost advantages playing a lesser, but still significant role. Macroeconomic and political stability were also taken into account. Investment incentives have not had a decisive influence on foreign direct investment inflows; however, the privatization process has affected the timing of foreign direct investment. Access to markets has been the primary motive for foreign direct investment; however, the absence of trade barriers and membership in free trade areas have been important for export-oriented investments. Foreign direct investment inflows have improved the overall growth potential of the economies under consideration, primarily through productivity improvements within foreign affiliates, rather than through linkages with domestic firms or spillovers
Physics Based Model for Cryogenic Chilldown and Loading. Part III: Correlations
In this report we discuss the details of the correlations used to recognize flow patterns and predict frictional losses, heat and mass transfer in the cryogenic two phase flow. The emphasis are put on the formulation of the correlation problem in terms of concise parametric and functional spaces allowing for efficient online search of the model parameters and accurate prediction of the phenomena observed during cryogenic loading. A special attention is paid to the discussion of the correlation dependence on the gravity. In this context the physics of stability, friction, and boiling in the two-phase flow that underlies the required correlations is discussed
From oil field to geothermal reservoir: assessment for geothermal utilization of two regionally extensive Devonian carbonate aquifers in Alberta, Canada
The Canadian province of
Alberta has one of the highest per capita CO2-equivalent emissions
in Canada, predominantly due to the industrial burning of coal for the
generation of electricity and mining operations in the oil sands deposits.
Alberta's geothermal potential could reduce CO2 emissions by
substituting at least some fossil fuels with geothermal energy.The Upper Devonian carbonate aquifer systems within the Alberta Basin are
promising target formations for geothermal energy. To assess their
geothermal reservoir potential, detailed knowledge of the thermophysical and
petrophysical rock properties is needed. An analogue study was conducted on
two regionally extensive Devonian carbonate aquifers, the Southesk-Cairn
Carbonate Complex and the Rimbey-Meadowbrook Reef Trend, to furnish a
preliminary assessment of the potential for geothermal utilization. Samples
taken from outcrops were used as analogues to equivalent formations in the
reservoir and correlated with core samples of the reservoir. Analogue
studies enable the determination and correlation of facies-related rock
properties to identify sedimentary, diagenetic, and structural variations,
allowing for more reliable reservoir property prediction.Rock samples were taken from several outcrops of Upper Devonian carbonates
in the Rocky Mountain Front Ranges and from four drill cores from the
stratigraphically equivalent Leduc Formation and three drill cores of the slightly
younger Nisku Formation in the subsurface of the Alberta Basin. The samples
were analyzed for several thermophysical and petrophysical properties, i.e.,
thermal conductivity, thermal diffusivity, and heat capacity, as well as
density, porosity, and permeability. Furthermore, open-file petrophysical
core data retrieved from the AccuMap database were used for correlation.The results from both carbonate complexes indicate good reservoir conditions
regarding geothermal utilization with an average reservoir porosity of about
8 %, average reservoir permeability between 10â12 and
10â15 m2, and relatively high thermal conductivities
ranging from 3 to 5 Wâmâ1âKâ1. The most promising target
reservoirs for hydrothermal utilisation are the completely dolomitized reef
sections. The measured rock properties of the Leduc Formation in the
subsurface show no significant differences between the Rimbey-Meadowbrook
Reef Trend and the Southesk-Cairn Carbonate Complex. Differences between the
dolomitized reef sections of the examined Leduc and Nisku Formation are also
minor to insignificant, whereas the deeper basinal facies of the Nisku
Formation differs significantly.In contrast, the outcrop analogue samples have lower porosity and
permeability, likely caused by low-grade metamorphism and deformation during
the Laramide orogeny that formed the Rocky Mountains. As such, the outcrop
analogues are not valid proxies for the buried reservoirs in the Alberta
Basin.Taken together, all available data suggest that dolomitization enhanced the
geothermal properties, but depositional patterns and other diagenetic
events, e.g., fracturing, also played an important role.</p
Bodily feeling in depersonalisation: a phenomenological account
publication-status: Publishedtypes: ArticlePre-print - please cite published version at Sage web site: http://emr.sagepub.com/content/4/2/145.full.pdf+htmlThis paper addresses the phenomenology of bodily feeling in depersonalisation disorder. We argue that not all bodily feelings are intentional states that have the body or part of it as their object. We distinguish three broad categories of bodily feeling: noematic feeling, noetic feeling and existential feeling. Then we show how an appreciation of the differences between them can contribute to an understanding of the depersonalisation experience.ER
Cloning and characterization of BCY1, a locus encoding a regulatory subunit of the cyclic AMP-dependent protein kinase in Saccharomyces cerevisiae
We have cloned a gene (BCY1) from the yeast Saccharomyces cerevisiae that encodes a regulatory subunit of the cyclic AMP-dependent protein kinase. The encoded protein has a structural organization similar to that of the RI and RII regulatory subunits of the mammalian cyclic AMP-dependent protein kinase. Strains of S. cerevisiae with disrupted BCY1 genes do not display a cyclic AMP-dependent protein kinase in vitro, fail to grow on many carbon sources, and are exquisitely sensitive to heat shock and starvation
Nuclear magnetic resonance as a quantitative tool to study interactions in biomacromolecules
High-resolution nuclear magnetic resonance (NMR) has emerged as one of the most versatile tools for the quantitative study of structure, kinetics, and thermodynamics of biomolecules and their interactions at atomic resolution. Traditionally, nuclear Overhauser enhancements (NOEs) and chemical shift perturbation methods are used to determine molecular geometries and to identify contact surfaces, but more recently, weak anisotropic orientation, anisotropic diffusion, and scalar couplings across hydrogen bonds provide additional information. Examples of such technologies are shown as applied to the quantitative characterization of function and thermodynamics of several biomacromolecules. In particular, (1) the structural and dynamical changes of the TipA multidrug resistance protein are followed upon antibiotic binding, (2) the trimer-monomer equilibrium and thermal unfolding of foldon, a small and very efficient trimerization domain of the T4 phagehead, is described in atomic detail, and (3) the changes of individual protein hydrogen bonds during thermal unfolding are quantitatively followed by scalar couplings across hydrogen bond
Inferential framework for two-fluid model of cryogenic chilldown
We report a development of probabilistic framework for parameter inference of cryogenic two-phase flow based on fast two-fluid solver. We introduce a concise set of cryogenic correlations and discuss its parameterization. We present results of application of proposed approach to the analysis of cryogenic chilldown in horizontal transfer line. We demonstrate simultaneous optimization of large number of model parameters obtained using global optimization algorithms. It is shown that the proposed approach allows accurate predictions of experimental data obtained both with saturated and sub-cooled liquid nitrogen flow. We discuss extension of predictive capabilities of the model to practical full scale systems
Foreign Direct Investments in Business Services: Transforming the VisegrĂĄd Four Region into a Knowledge-based Economy?
Foreign direct investments (FDIs) in the service sector are widely attributed an important role in bringing more skill-intensive activities into the Visegrad Four (V4). This regionâcomprising Poland, the Czech Republic, Hungary and Slovakiaârelied heavily on FDIs in manufacturing, which was often found to generate activities with limited skill content. This contribution deconstructs the chaotic concept of âbusiness servicesâ by analysing the actual nature of service sector activities outsourced and offshored to the V4. Using the knowledge-based economy (KBE) as a benchmark, the paper assesses the potential of service sector outsourcing in contributing to regional competitiveness by increasing the innovative capacity. It also discusses the role of state policies towards service sector FDI (SFDI). The analysis combines data obtained from case studies undertaken in service sector outsourcing projects in V4 countries. Moreover, it draws on interviews with senior employees of investment promotion agencies and publicly available data and statistics on activities within the service sector in the region. It argues that the recent inward investments in business services in the V4 mainly utilize existing local human capital resources, and their contribution to the development of the KBE is limited to employment creation and demand for skilled labour
Delusional beliefs and reason giving
Delusions are often regarded as irrational beliefs, but their irrationality is not sufficient to explain what is pathological about them. In this paper we ask whether deluded subjects have the capacity to support the content of their delusions with reasons, that is, whether they can author their delusional states. The hypothesis that delusions are characterised by a failure of authorship, which is a dimension of self knowledge, deserves to be
empirically tested because (a) it has the potential to account for the distinction between endorsing a delusion and endorsing a framework belief; (b) it contributes to a
philosophical analysis of the relationship between rationality and self knowledge; and (c) it informs diagnosis and therapy in clinical psychiatry. However, authorship cannot provide a demarcation criterion between delusions and other irrational belief states
