Ekmekci, Dursun; Bülbül, Ferhat
Ni-B/SiO2, Al2O3, TiO2 and CuO composite coatings were successfully obtained by the electroless plating technique. Dispersible SiO2, Al2O3, TiO2 and CuO nanoparticles were co-deposited with electroless Ni-B coating onto AISI-304 steel substrates. Deposits were characterized for its structural properties by X-ray diffraction (XRD). XRD results showed a broad peak of Ni-B and low intensity composite nanoparticle peaks. The surface and cross-section morphology of samples were analysed using a scanning electron microscope (SEM). Surface analysis showed that the incorporation in Ni-B matrix of nano-SiO2, Al2O3, TiO2 and CuO particles increases the nodularity of composite coatings. The deposits are composed of a columnar structure grown along the vertical direction of the substrate surface. The results also show that electroless nanocomposite coatings tend to have greater microhardness compared with the coating without nanoparticles. The increase in the microhardness of the nanocomposite coatings reported in this study is attributed to an effect of dispersion strengthening of ceramic particles in the Ni-B matrix.

Çelebi, S.; Ozturk, A.; Uysal, E.; Kutuk, S.; Duzgun, I.
The evolution of the rate of flux creep along the major hysteresis envelopes in a Y0.5Lu0.5Ba2Ca3Oy sample synthesized by a modified melt powder melt growth (MPMG) method at 25 K has been investigated. Magnetic relaxation rates depend strongly on the prior magnetic history. Calculations based on the critical state model can reproduce quite well the experimental data for magnetization when we have chosen the field exponent n = 0.3 in critical current density, Jc(Ha) = Jc0/(Ha−IM)n, where IM = Ha when 0 < H < Hc1 and (Formula presented.) when Ha ≥ Hc1. Using the field-cooled magnetization MFC data as well as the comparison of experimental and calculated M–H hysteresis loop, we estimated Hc1 = 500 Oe, p = 0, and the penetration field H∗ = 20 kOe. The apparent pinning energy was estimated as 62 meV for the remanent magnetization upon an excursion of 40 kOe.

Baki, Birdogan; Peker, Iskender
In this paper, an integrated approach, in which Fuzzy Analytic Hierarchy Process (FAHP) and Fuzzy TOPSIS (FTOPSIS) is used, is proposed to rank the hospitals according to service quality from the patient's point of view. The FAHP is employed to determine the weights of service quality criteria for the hospitals, and FTOPSIS method is used to rank the hospitals. Empirical results show that when "reliability" is the most important criterion, "empathy" is the least important criterion in terms of hospital service quality. A sensitivity analysis is also applied to check how sensitive our model is to changes in the various criteria weights.

Duran, Celal; Ozdes, Duygu; Akcay, Hakki Turker; Serencam, Huseyin; Tufekci, Mehmet
ABSTRACT: In the present study, Cd(II), Co(II), and Ni(II) ions were separated and preconcentrated via carrier element-free coprecipitation (CEFC) method by using an organic coprecipitating agent, 1,2-bis-(2-tosyl ethoxy) benzene (BTEB), prior to their flame atomic absorption spectrometric (FAAS) detections. The experimental conditions were optimized in terms of pH of the aqueous solution, BTEB amount, standing time, centrifugation rate and time, and sample volume. Under the optimum experimental conditions, the detection limits for Cd(II), Co(II), and Ni(II) ions were found to be 0.13, 0.67, and 0.46 μg L−1, respectively, and the relative standard deviations for the analyte ions were found to be lower than 4.0%. The accuracy of the method was tested by analyzing certified reference material and spike tests. The method was applied to determine the levels of Cd(II), Co(II), and Ni(II) ions in sea and stream water, macaroni, red lentil, and cracked wheat samples.

Çakir, Günay; Özdemir, Mehmet
The forest conservation organizations in Turkey have recommended changing the classical forest management systems to protect forest biodiversity since 2006. This study discusses the spatio-temporal analysis of forest management activities and land use changes in Yalova Forest Ecosystems, Turkey. We focused on the Yalova City because (a) it is located in a highly urbanized area, northwestern Turkey, (b) forest is a governmental ownership and producing of many non-wood forest product and wildlife species, (c) governmental organizations are encouraged to be decreased clear-cuts to protect forest ecosystems; (d) GIS databases are available in Yalova; (e) Yalova Forestry Administration has a membership of the Mediterranean Model Forest Network in 2011, and (f) many new forest policies will be developed in Turkey after the membership of the model forest. This study used forest management plans of Yalova Forest during 1971–2008 periods and analyzed data in geographic information system (GIS). Results showed that the rate of forest area in the Yalova steadily increased from 53.4 % in 1971 to 61.2 % to 62.5 % between 1994 and 2008 respectively.

İncele - MakaleYalnız künye2015Scopus SJRQ4The effects of the CSR isomorphism on both CSP and CFP
Ilhan-Nas, Tülay; Koparan, Emrah; Okan, Tarhan
Purpose – The purpose of this study is to contribute to the understanding of the interrelationships between corporate social responsibility (CSR) isomorphism of headquarters (HQs) and their subsidiaries as well as corporate social performance (CSP) and corporate financial performance (CFP) at the subsidiary level. Design/methodology/approach – This study tested these relationships through canonical correlation analyses. The data used were drawn from corporate HQ and 63 subsidiaries, which were publicly listed on the Istanbul Stock Exchange in 2007. Both qualitative and quantitative techniques were used in the study. Findings – The results generally indicated that the isomorphism between the CSR practices of the HQ and those of their subsidiaries could impact both the CSP, especially the product and employee dimensions, and the CFP. No relationship was found to exist between the CSP and CFP. Originality/value – Despite extensive interest by scholars and practitioners in the subject area, relatively little is known about the management of CSR by the multinational enterprises (MNEs) (Meyer, 2004), as the literature does not systematically examine the effects that occur on employee performance following the diffusion of CSR among the MNEs subsidiaries. Extending earlier literature on CSR, by integrating the effect of the CFP, the present study focuses on the effects of isomorphism between the CSR practices of the MNEs and those of their subsidiaries on both CSP and CFP. Further, the study examined the interrelation of CSP and CFP from the perspective of international management. Given the increased interest in corporate governance matters at the international level, CSR plays a central and fundamentally important role in the corporate governance of the MNEs because of both globalization forces and the pressures exerted by stakeholders. In this context, this paper is one of the first to explore the transfer of CSR practices from the MNEs to their subsidiaries. The effect of CSR on performance is an important research question, especially for emerging markets (Ibrahim and Angelidis, 1995; Waddock and Graves, 1997; Ghazali, 2007; Johnson and Greening, 1999). Despite the importance of this issue, however, until recently, only a limited discussion has been evident in the literature on CSR in the international arena with particular reference given to the emerging economies. Studying the effects of the CSR isomorphism on the performance in Turkish context is justified in three ways. First, Turkey is the largest emerging economy in Eastern Europe, the Balkans and the Middle East (Tatoglu et al., 2003, p. 7). It presents the emerging nature of the market and the transitional characteristics of the institutional environment (Cavusgil et al., 2002). Second, the drivers for CSR in Turkey, such as the other emerging markets whose institutional characteristics and economic fundamentals is similar, are exogenous and institutional rather than endogenous factors (Ararat and Gocenoglu, 2006, p. 11). Excluding the philanthropic activities, the very first manifestations of CSR were observed in the business conduct of MNEs in Turkey (Ararat and Gocenoglu, 2006, p. 11). MNEs have a dominant and leader role in Turkey for CSR practices. Finally, the subsidiaries operating in Turkey are less likely to resist the transfer of the organizational policies and practices such as human resource management policies (Sayim, 2010, 2011) and organizational culture (Ilhan, 2008). In fact, they want to even transfer the policies and practices from MNEs (Sayim 2010, 2011; Ilhan, 2008). Therefore, Turkish context provides a good case to test the effects of the CSR isomorphism on the performance.

Bostan, Sedat; Salih Güran, M.
The Objective of the Study: The objective of this study was to analyze and evaluate the complaint calls made between the years of 2004 and 2009 to the Communication Center of The Ministry of Health that was founded within the framework of "The Transformation in Healthcare Project" and thus to make a contribution by providing an introducing general view of the functionality of the feedback mechanism. The Method: The sample of the study consists of 686.397 appeal calls that were made to the Ministry of Health's Communication Center between the years 2004 and 2009. The complaints have been studied in relation to a range of factors like the months of the complaints, the hour of the day, the days of the week, the age groups of the complainers, gender, and type of the complaint and the reason of complaint. Findings: By answering not only to health related appeals, but also to virtually any issue of interest for the citizens, SABIM achieved a plural involvement of the stakeholders and an "interactive administration". It realized feedback mechanisms that enabled the real-time assessment of services as they were being supplied, thus eliminating many problems that arise from lack of communication.

Background: The emergence of carbapenem-resistant Klebsiella pneumoniae poses a serious problem to antibiotic management. We investigated the beta-lactamases in a group of carbapenem-resistant K. pneumoniae clinical isolates from Turkey. Methods: Thirty-seven strains of K. pneumoniae isolated from various clinical specimens were analyzed by antimicrobial susceptibility testing, PCR for the detection of p-lactamase genes, DNA sequencing, and repetitive extragenic palindronic (REP)- FOR analysis. Results: All 37 isolates were resistant to ampicillin, ampicillin/sulbactam, piperacillin, piperacillin/tazobactam, ceftazidime, cefoperazone/sulbactam, cefepime, imipenem, and meropenem. The lowest resistance rates were observed for colistin (2.7%), tigecycline (11%), and amikacin (19%). According to FOR and sequencing results, 98% (36/37) of strains carried at least one carbapenemase gene, with 32 (86%) carrying OXA-48 and 7 (19%) carrying NDM-1. No other carbapenemase genes were identified. All strains carried a CTX-M-2-like beta-lactamase, and some carried SHV- (97%), TEM- (9%), and CTX-M-1-like (62%) beta-lactamases. Sequence analysis of bla(TEM) genes identified a bla(TEM-166) with an amino acid change at position 53 (Arg53Gly) from bla(TEM-1b), the first report of a mutation in this region. REP-FOR analysis revealed that there were seven different clonal groups, and temporo-spatial links were identified within these groups. Conclusions: Combinations of beta-lactamases were found in all strains, with the most common being OXA-48, SHV, TEM, and CTX-M-type (76% of strains). We have reported, for the first time, a high prevalence of the NDM-1 (19%) carbapenemase in carbapenem-resistant K. pneumoniae from Turkey. These enzymes often co-exist with other beta-lactamases, such as TEM, SHV, and CTX-M beta-lactamases.

Antioxidant activity of the juice and seed and skin extracts prepared with methanol, acetonitrile, and water of Viburnum opulus L. grown in Eastern Black Sea Region were studied with an on-line HPLC-ABTS method and off-line antioxidant methods, among which a linear positive correlation was observed. The fruit extracts were analysed with the HPLC-UV method optimised with 14 standard phenolics. Identification of the phenolic components in the juice was made using an HPLC-UV-ESI-MS method. Nineteen phenolic compounds in juice were identified by comparing the retention times and mass spectra with those of the standards and the phenolics reported in the literature. The major peaks in the juice belonged to coumaroyl-quinic acid, chlorogenic acid, procyanidin B2, and procyanidin trimer. Quite different antioxidant composition profiles were obtained from the extracts with the solvents of different polarities. The antioxidant activities of the seed extracts were higher than those of the skin extracts in general. (C) 2014 Elsevier Ltd. All rights reserved.

Background: This study aims to evaluate the potential of ischemia-modified albumin (IMA) to predict the myocardial infarction in on pump coronary artery bypass grafting (ONCABG) patients. Methods: Fifty elective isolated ONCABG patients (41 males, 9 females; mean age 66 years; range 56 to 75 years) were included in the study. Patients were divided into perioperative myocardial infarction (PMI; n=8) and non-infarction (NPMI; n=42) groups according to perioperative cardiac troponin I (cTnI) values and ECG findings. Serum IMA levels were measured preoperatively, 20 minutes after aortic cross clamping, 30 minutes, at 3, 6, 12 and 24 hours after declamping. Results: Compared to the NPMI group, the declamping 30 minutes, 3, 6 and 12 hours IMA levels were higher in the PMI group (p=0.002, p=0.048, p=0.023, p=0.007, respectively). In both NPMI and PMI groups, the 20 minutes after aortic cross clamping IMA levels were higher compared to the preoperative IMA levels (p=0.0001, p=0.038, respectively). Conclusion: Our study results show that IMA may be an early marker of myocardial infarction in the ONCABG patients.

Grain yield estimate from early segregating populations is an interesting feature of today's wheat breeding programs, and F-1 populations are generally recommended as the most suitable population by researchers. In the present study, we evaluated the population vigor of diallel F-4 offsprings of six bread wheat genotypes (Sultan, Bezostaya, Suzen, Harmankaya, Altay and Gerek) under irrigated (IR) and rain-fed conditions (RF). The experiment as two sets under IR and RF were established in the field of Anatolian Agricultural Research Institute, Eskisehir. The mean of grain yield (5468 kg ha(-1)) of F-4 populations in RF and IR had been lower than the mean of genotypes (5654 kg ha(-1)). The mean of grain yield of genotypes (7062 kg ha(-1)) under IR was higher than F-4 populations (6703 kg ha(-1)), while genotypes and F-4 populations were nearly similar under RF (4246 kg ha(-1) and 4234 kg ha(-1), respectively). The mid-variety population vigor for grain yield varied from -6.70% (Hrm/Grk) to 8.77% (Bez/Grk) under RF, and from -22.58% (Sltn/Alty) to 10.87% (Bez/Suzen) under IR. There was not positive significance population vigor in F(4)s. According to results under RF and IR, F-4 populations are observed as the most suitable populations for realistically estimation of grain yield performance of populations.

Undoubtedly the most important change in Ottoman provincial administration in the 19th century was the centralizing activities taken by Mahmud II. The new government policy based on the limitation of power of ayan families who had a long history in the ottoman provinces, and on the reestablishment of central control demonstrated its impact in the Eastern Black Sea region. The region was a scene of long term struggle between governors that represents the central power and local notables in the first thirty years of the 19th century. The implementation of Tanzimat reforms in the area, as a next phase of this struggle period, created a large discontented group that their interests damaged by new Tanzimat reforms which required not only administrative but fiscal centralizing and other new applications. Although a part of this discontented group was integrated into the new system, this process was a little more painful in some part of the empire like eastern side of Trabzon Province. The period of disorders lasted between 1840-1846 in Adjara, a buffer zone on the Ottoman-Russian border, revealed an example of the own system of local notables (ayan) of Black Sea Region and showed the vulnerability and fragility of the region to the internal and external developments. In this context based on the Ottoman and French archival documents, this study aims to evaluate the emergence and causes of rebellions of Kor Huseyin Bey, who was a member of the Selim Pasazadeler, one of the most important ayan families in Adjara in 1840 and 1846 which led to a climate of anarchy and their effects on the region.

The Ottoman Empire, gave importance managing and running mines in its own territories from its foundation period. The Empire which took advantage of experience of the conquered regions improved mining industry to the competitive level with Europe in the 15th and 16th centuries. But the Empire was not able to keep pace with developments since 18th century and fell behind with the industry. It consequently took some steps to stimulate the sector. So that, many native's businessmen of Muslim and non-Muslim aspired that to mines in Licese, but they could not manage a stable. In this period, European companies applied for the Licese mine in the sanjak of Karahisar-i Sarki, as well as the other mines in Anatolia. The most important of these companies is British Asia Minor Mining Company. After Asia Minor Mining Company had purchased the mine in Licese, economy of region revived. Activities of company have changed patterns of work in the region. The inhabitants who previously engaged in farming began to receive a sallary as provision of effort. However, the activities of company in the region caused to security and political problems. In this work, we deal with the status the mines in Licese and the economic, social and political effects of the mining activities of Asia Minor Mining Company in the region.

In total, 95% of all business enterprises established in Turkey are micro-scale, and this figure increases to 98.6% in the forest products industry. Micro-scale enterprises are important in terms of production, employment, and overcoming economic imbalances among regions. The forest products industry, which includes three subdivisions within the manufacturing sector, occupies an important place in the overall Turkish manufacturing sector. Thus, this study examined the structural characteristics of forest product enterprises in Gumushane Province. The research involved in-person interviews with personnel at 47 enterprises. The data revealed that the sawmill division was especially important with respect to the use of local poplar logs. The sawmill and furniture divisions accounted for 28% of all enterprises and 26% of all employees in the manufacturing sector in Gumushane. We found that 57% of enterprises had difficulty in finding working capital and 55% of enterprises experienced shortages of labour. The average contribution of each forest products business to employment (2.55) was more than that of other manufacturers in Gumushane (2.27). The forest product businesses in Gumushane resemble other micro-scale enterprises located in other regions of Turkey in terms of their structural properties.

This study analyzes the nonstationarity of per capita real GDP for 11 Middle East and North Africa (MENA) Countries over the period 1970 to 2012 using two recently developed methods. SURADF and CADF panel unit root tests allowing for cross sectional dependence are used to determine whether output fluctuations are permanent or transitory. Contrary to the traditional view of business cycle, we find econometric evidence supporting the idea that the output fluctuations in MENA region are mostly permanent. These results also emphasize that the effectiveness of stabilization policies aimed at real output by the government should be reviewed to achieve longlasting results.

In this study it is analyzed whether there is a cause-and-effect relationship between inflation and budget deficit in Turkey with the annual data covering the time period between 19782002 when inflation was high and chronic. Econometric methods used in the study is based on the Johansen co-integration analysis and Granger causality connected error correction model. Empirical results suggest that in the longrun budget deficit and inflation is co-integrated, while budget deficit is Granger cause of inflation in short-run. However, inflation is not Granger cause of budget deficit. In other wordse causality is unilateral. The research also found that, response of inflation to a percentage increase in budget deficit is greater than ten percent in short-run.
