Eigenvalue Asymptotics for the Schr\"odinger Operator with a Matrix Potential in a Single Resonance Domain

We consider a Schr\"odinger Operator with a matrix potential defined in $L_2^m(F)$ by the differential expression\begin{equation*} L(\phi(x))=(-\Delta+V(x))\phi(x) \end{equation*}and the Neumann boundary condition, where $F$ is the $d$ dimensional rectangle and $V$ is a martix potential, $m\geqslant 2, d\geqslant 2$. We obtain the asymptotic formulas of arbitrary order for the single resonance eigenvalues of the Schr\"odinger operator in $L_2^m(F)$.Comment: Presented by Setenay Akduman in the International Conference "Analysis, Topoogy and Applications (ATA 2014)", Vrnja\v{c}ka Banja, Serbia, May 26-29, 2014, Keywords: Schr\"odinger operator, Neumann condition, perturbation, matrix potentia

European Integration and Regional Specialization Patterns in Turkey's Manufacturing Industry

The dynamics of industrial agglomeration across the regions and the reasons for such agglomeration have been the focus of interest particularly in exploring the effects of economic integration of regions on the spatial distribution of economic activity. In this context, following the predictions of the literature on economic geography, Turkey’s integration with the European Union as a candidate member is a likely cause of changes in economic dispersion of the economic activity over the years. The major objective of the study is to complement the findings of the studies on industrial agglomeration in Turkey’s manufacturing industry by exploring whether specialization and concentration patterns have changed over time and to expose the driving forces of geographic concentration in Turkey’s manufacturing industry, particularly during Turkey’s economic integration process with the European Union under the customs union established in 1996. Industrial concentration and regional specialization are measured by GINI index for NUTS 2 regions at the 2-digit level for the years between 1992 and 2001. To investigate which variables determine industry concentration, the systematic relation between the characteristics of the industry and geographical concentration is tested. A regression equation is estimated, where the dependent variable is GINI concentration index and the independent variables are the variables that represent the characteristics of the sectors. The major finding of the study is that Turkey’s manufacturing industry has a tendency for regional specialization. Increase in the average value for regional specialization supports the prediction developed by Krugman that regions become more specialized with regional integration. But there is no evidence for increased industrial concentration in Turkish manufacturing industry, contrary to the expectations. As for the answer to which variables determine industry concentration, the analysis supports the hypothesis that the firms tend to cluster in regions where there are economies of scale and there are significant linkages between firms, supporting the predictions of new trade theory and economic geography.Regional specialization, geographical concentration, economic integration, geographical economics

THE SYNERGY BETWEEN SUBSECTOR COMPETITIVENESS AND REGIONAL DEVELOPMENT: THE CASE OF TURKEY AND THE TOMATO SUBSECTOR

Abstract This study develops a conceptual model of the institutions and key factors that facilitate competitiveness on the national and subsector level and then determines how linkages between the factors that enhance competitiveness and regional development can be created. Turkey and the Turkish tomato subsector provided the case to test this model.Regional development, sustainable competitiveness, tomato processing industry, Turkey, industry clusters, Community/Rural/Urban Development,

PATHWAYS TO COOPERATION: A RELATIONAL THEORY OF REBEL ALLIANCE FORMATION

Why do some rebel organizations initiate a united front while others confine themselves to a loose partnership? Existing research on armed movements suggests that insurgents should quickly leave cooperative agreements when doing so will provide particular advantages in a post-conflict setting. Still, rebels often build diverse alliances, ranging from joint attacks to shared command structures. If rebel groups are indeed purely pragmatic entities, why would they tie themselves to a partnership that hinders their ability to defect quickly? In this dissertation, I argue that three relational factors shape how insurgents cooperate: a) rebel-civilian relations (overlapping civilian support), b) inter-rebel relations (shared allies), and c) rebel-sponsor relations (common external patrons). Militant groups connected through these social networks will more likely facilitate united armed opposition thanks to shared channels of trust and reciprocity. Developing a new dyadic dataset, I find support that sharing allies or civilian support is positively correlated with forming a united front. Yet, state sponsorship does not produce similar results

Competitiveness of Turkeys Organic Exports in the European Union Market

Turkeys exports of organically produced agricultural products have been rapidly growing particularly in response to increasing demand in the European Union countries. Common view and findings of the research on organic trade in Turkey confirms that European market is expanding. A lacking component of the existing research on Turkeys organic exports is that none of the studies focused on modeling the export market for organic products which would enable to make forecasts as well as to make analysis for policy implications. Another missing component of the stream of studies on trade of Turkish organic commodities is the lack of understanding of the present situation of the competitiveness of Turkish exports in the European Union market. The study therefore focuses on estimating an econometric export demand function for organic products and exploring the competitiveness and export performance of Turkish exports as well as understanding the components of export performance. An effort to estimate an econometric export demand model for Turkeys organic exports and revealing sources of export performance and competitiveness is what makes the present study a unique one. The project has three major objectives and thus seeks to produce three outputs: The first objective is to estimate an export demand model for Turkish organic products in the European Union market. It is therefore possible to estimate price and income elasticities of demand as well as to make projections. The second objective is to explore Turkeys export competitiveness in organic products in the European Union market. It order to fulfill this objective, we will estimate indices to measure Turkeys competitiveness. The third objective is to investigate export competitiveness and determine the components of export performance. Through constant market share analysis, we seek to determine the key factors underlying the growth or Turkeys organic exports. The study reveals that export demand for the Turkish organic products are growing and sensitive to price and income changes in target countries. Turkey has a clear comparative advantage against the rival EU countries in selected products. Competitiveness is particularly due to relative prices, thus does not indicate a sustainable competitiveness due to lack of added value in the export items.Organic Agriculture, Turkish Agriculture, Export Demand, Competitiveness, Turkish Organic Exports, International Relations/Trade, Livestock Production/Industries,
