Firm productivity, exchange rate movements, sources of finance and export orientation

We investigate the level and volatility effects of exchange rates on the productivity growth of manufacturing firms with heterogenous access to debt, and domestic and foreign equity markets in Turkey. We find that while exchange rate volatility affects productivity growth negatively, having access to foreign or domestic equity, or debt markets does not alleviate these effects. Furthermore, foreign owned or publicly traded companies do not appear to perform significantly better than the rest. We detect, however, that firm productivity is positively related to having access to external credit. Additionally, we find that while export (inward) oriented firms are affected less (more) by exchange rate appreciations, they are more (less) sensitive to exchange rate volatility

Trade Flows, Exchange Rate Uncertainty and Financial Depth: Evidence from 28 Emerging Countries

We investigate the effects of real exchange rate uncertainty and financial depth on manufactures exports from 28 emerging economies to the North and South over 1978-2005. We estimate a dynamic panel model using system GMM approach and show that for the majority of countries in our sample exchange rate uncertainty affects both South-South and South-North trade negatively. Furthermore, for several cases we discover that this effect is unidirectional, that is South-South or South-North. In addition, we find that while financial depth plays a trade-enhancing role, exchange rate shocks can negate this effect. We also show that trade among developing economies is likely to enhance export growth

Innovation Strategies and Challenges in Emerging Economies: The Case of Research and Technology Organizations in Turkey

Innovation is highly critical for every company, especially for technology-based organizations looking to sustain their competitive advantage. However, this is not an easy task. Regardless of the size of the enterprise, market and location, all organizations face numerous challenges. Even though huge barriers to innovation exist in different countries, firm- and industry-specific challenges can be distinguished. This paper examines innovation strategies and obstacles to innovation in research and technology organizations (RTO) of Turkey. From the most important to the least, nine different challenges are ranked according the results of this survey. The findings reveal that to take the lead in innovation, financial constraint is the biggest challenge, which is consistent with the related literature. It ranked number one in this study. Beyond that, based on a sample of 40 RTOs, regional challenges such as underdeveloped regional innovation ecosystem plays a significant role in hampering innovation. Most of the organizations (55%) embrace an incremental approach to innovation, while only few pursue radical shifts. About 40% of the RTOs focus on product innovation, and 27.5% of them concentrate on technological innovation, while a very limited number aim for operational excellence and customer engagement as the focus of their strategic innovation efforts

The effect of supersymmetric CP phases on Chargino-Pair Production via Drell-Yan Process at the LHC

We compute the rates for pp annihilation into chargino-pairs via Drell-Yan process taking into account the effects of supersymmetric soft phases, at proton-proton collider. In particular, the phase of the mu parameter gains direct accessibility via the production of dissimilar charginos. The phases of the trilinear soft masses do not have a significant effect on the cross sections.Comment: 24 pages, 7 figure

On the Coulomb-Sturmian matrix elements of the Coulomb Green's operator

The two-body Coulomb Hamiltonian, when calculated in Coulomb-Sturmian basis, has an infinite symmetric tridiagonal form, also known as Jacobi matrix form. This Jacobi matrix structure involves a continued fraction representation for the inverse of the Green's matrix. The continued fraction can be transformed to a ratio of two $_{2}F_{1}$ hypergeometric functions. From this result we find an exact analytic formula for the matrix elements of the Green's operator of the Coulomb Hamiltonian.Comment: 8 page

Comparative study of CW, nanosecond- and femtosecond-pulsed laser microcutting of AZ31 magnesium alloy stents

Magnesium alloys constitute an interesting solution for cardiovascular stents due to their biocompatibility and biodegradability in human body. Laser microcutting is the industrially accepted method for stent manufacturing. However, the laser-material interaction should be well investigated to control the quality characteristics of the microcutting process that concern the surface roughness, chemical composition, and microstructure of the final device. Despite the recent developments in industrial laser systems, a universal laser source that can be manipulated flexibly in terms of process parameters is far from reality. Therefore, comparative studies are required to demonstrate processing capabilities. In particular, the laser pulse duration is a key factor determining the processing regime. This work approaches the laser microcutting of AZ31 Mg alloy from the perspective of a comparative study to evaluate the machining capabilities in continuous wave (CW), ns- and fs-pulsed regimes. Three industrial grade machining systems were compared to reach a benchmark in machining quality, productivity, and ease of postprocessing. The results confirmed that moving toward the ultrashort pulse domain the machining quality increases, but the need for postprocessing remains. The real advantage of ultrashort pulsed machining was the ease in postprocessing and maintaining geometrical integrity of the stent mesh after chemical etching. Resultantly, the overall production cycle time was shortest for fs-pulsed laser system, despite the fact that CW laser system provided highest cutting speed

Relaxation of the Dynamical Gluino Phase and Unambiguous Electric Dipole Moments

We propose a new axionic solution of the strong CP problem with a Peccei-Quinn mechanism using the gluino rather than quarks. The spontaneous breaking of this new global U(1) at 10^{11} GeV also generates the supersymmetry breaking scale of 1 TeV (solving the so-called \mu problem at the same time) and results in the MSSM (Minimal Supersymmetric Standard Model) with R parity conservation. In this framework, electric dipole moments become calculable without ambiguity.Comment: Typos corrected and a footnote added, 10 p

The Investigation of Some Mohair Mineral Levels (Mg, Fe, Cu, Zn) of Angora Goats in Original Zone of Ankara Province

In this study, determination of some mineral levels of mohair samples obtained from Angora goats (Capra hircus ancyrensis) bred in villages of Basayas (1st farm, n=28 goats) and Yagmurdede (2nd farm, n=30 goats) in Ankara province of Turkey was aimed. Totally 58 goats (2-4 years old) in two farms kept under similar managemental conditions and based on pasture were chosen as research materials. Mohair samples from mid-side of the goats were collected to determine the levels of magnesium (Mg), iron (Fe), copper (Cu) and zinc (Zn) by atomic absorption spectrophotometer (AAS) (M series V1, 23). The mohair mineral levels in the 1st and the 2nd farm of Angoras were found as 22.234 ± 1.030 μg/g and 20.952 ± 1.462 μg/g for Mg; 37.716 ± 1.573 μg/g and 32.271 ± 1.397 μg/g for Fe (P<0.05); 4.248 ± 0.293 μg/g and 7.169 ± 0.285 μg/g for Cu (P<0.001); 60.673 ± 2.395 μg/g and 62.802 ± 3.172 μg/g for Zn, respectively. In the 1st and the 2nd farm, non-significant positive and negative correlations between minerals were discovered. The estimated correlation coefficient between Fe and Cu was negative (r = ˗ 0.291) significant in total population (P<0.05)
