Sezerel, Hakan; Tonus, H. Zumrut; Ozsahin, M
Workforce diversity imposes itself as an imperative for organizations. Hence, today's organizations distinguish the diversified workforce as a tool to leverage business opportunities. In order to acquire a competitive advantage from human resources, diversity management comes to the front for all organizations. Managing diversity successfully requires a proper diversity climate for employees in all levels of organizations. This study reports the findings of a research study on the diversity climate among employees of a hotel chain. Both the t-test and one way ANOVA tests predict the perception of employees. The results show that diversity perceptions of employees predominantly depend on managerial status. (C) 2014 The Authors. Published by Elsevier Ltd.

Yildirim, Mustafa; Çakmak, Mustafa
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.

Top, Yener; Adanur, Hakan; Öz, Mehmet; Yasar, Mehmet
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.

Dogan, Caglayan; Cubukcu, F
Some Explicit Polaroids is one of the most sensational plays reflects consumerist culture of 2000s twentysometings is described as controversial. Some Explicit Polaroids is a political criticism on the confrontation of the two generations and reflects consumerist tenets, which hold values of globalisation. This study tries to prove that Ravenhill's work is totally reflection of the logic of consumerism and post-consumerism in terms of contemporary British society that is subjected to contemporary plays mostly. This study particularly unveils the perception of consumerist culture that is embodied within the scope of Ravenhill's perspective on British society; therefore, it aims to shed some light the globalised and cruelly capitalised world. The beginning of this study discusses the ongoing understanding of theatre and its representative perspectives after nasty nineties, as well as the social, economic, and political processes that led to the arrival of In-Yer-Face Theatre. Additionally, Mark Ravenhill's theatre aesthetic and his contributions towards contemporary British Theatre are briefly revealed. In this study, the evaluations written on consumerism and globalization are dealt with according to their resonances in the play. (C) 2015 The Authors. Published by Elsevier Ltd.

One of the dominant subjects of Quranic sciences, Muteshabihu'l Quran is presented in a different approach and classification in this study. The approach contains a classification which will help us to see unity. The data having no practical value and not helping us understand Quran or use related information in terms of methodology will not take place in the classification while muteshabihat (ambiguity) and some new information will be involved. On the other hand, this triple classification is a practical one which will help us put historical information and discussions into place. In the classification, Muteshabihu'l Quran will be analyzed under three main titles as follow: 1. Literal similarity, 2. Muteshabihat (ambiguity) discussed within the context of the verse 3/7 in Al-i Imran (Surah), and 3. Muteshabihat formed within the scope of the attributes of Allah. In the study, some overlooked approaches will be brought to the attention of readers, and some efforts will be made for linguistic, historical and socio-cultural understanding of the subject.

Yilmaz, Ozgur
The French Revolution and the invasion of Egypt created a crisis period in Ottoman-French relations and also arrested the French initiatives to trade in the Black Sea from the 17th century. However, on 25 July 1802 with the Treaty of Paris, the French were also given the right to trade in the Black Sea. In this way, France added the Black Sea to his privileges. With the 2nd and 3rd articles of the treaty, France has obtained the right to create consular agents on various points of the Black Sea. In this context, by a decision of 21 September 1802, a general consulate in Sinop and two consular agents in Trabzon and Eregli, depended to consulate general of Sinop, established. Pascal Fourcade was appointed as consul to Sinop and arrived to the city in the October of 1803. Fourcade was welcomed in a good way in Sinop; but the anarchy reigned in Anatolia after the Tayyar Pasha's exile, and intrigues of Russian colleague, Konuchenco, Fourcade stayed in difficult situations in the city. In fact, the preference of Sinop, as a general consulate centre was not in accordance with the terms of the period. Although Sinop had one of the best ports of the Southern Black Sea, the city was not as active as in the past on a commercial basis. It is known that Sinop was one of the places that mostly affected by Ottoman-Russian wars. Sinop had profited commercial relation that took place between the north-south ports of the Black Sea under the Ottoman dominance over the Black Sea. Especially in trade with Crimea, Sinop was the main port for Anatolian products. However, ever-expanding dominance of the Russia over the Black Sea, not only affected commercial relations between Black Sea ports but also started a decline period for southern Black Sea ports as Sinop and Trabzon that had strong commercial affairs with northern Black Sea. In this state Sinop was a small coastal town in the beginning of 19th century. But as the French consul stated, Sinop would became a strategic position as a port for trade of Anatolia and Iran in case of favourable conditions. Fourcade had very high expectations for the future of the city. The most important task of French consul was to achieve new markets for French goods; receive raw materials coming from Iran and Anatolia and establish warehouses for goods in Sinop. In this regard, Fourcade was describing the city as a trading port that had a very bright future and comparing the city to Alexandria and Baghdad, and also trying to show that Sinop was better port than Samsun and Trabzon. Fourcade's these expectations were not only connected to the creation of favourable conditions for trade and establishment of the necessary infrastructure. In fact, the realization of these plans depended on Tayyar Pasha's power, the governor of southern Black Sea region. As Fourcade's words, the main purpose of the consul was to establish good relations with Tayyar Pasa and convince him to gains of future French trade in his region. In the spring of 1804, Fourcade met with Tayyar Pasha and achieved positive results for his future plans; but because of obstructions of Russian consul in Sinop Fourcade did not realize his plans that emerged after the consul and Tayyar Pasa's interview in Bafra. Moreover defeat of Tayyar Pasha by Yusuf Pasha and exile to Sohum in 1805 created a real period of solitude for Fourcade in Sinop. Fourcade was met in early days in Sinop with Russian jealousy. When he arrived to Sinop, the city had been hosting Russian consuls since 1785. So, the biggest obstacle to plans of French consul was the Russian colleague Konuchenco. As the agent of Russia who did not want another European power in Black Sea, Konuchenco showed all his effort to fail Fourcade's mission in Sinop. In this context it is difficult to say that French Foreign Ministry predicted Russian rivalry in the Black Sea ports. Whereas with the Treaty of Kucuk Kaynarca, Russian had gained to right to trade in Black Sea and soon after the treaty they established a consular network in the port cities. Sinop was one the port cities that the Russian preferred to create a consular agent. Russian consuls in Sinop were so powerful that they could change kadi of Sinop. There were also very strong relations between Russian consul Konuchenco and Tayyar Pasa who had territories in Crimea consigned to Battal Huseyin Pasa, father of Tayyar Pasa, in his exile in Russia. In the first two years of consulate, Fourcade complained so often the relations between Tayyar Pasa and Konuchenco and Russian dominance over the Sublime Porte that seen in Sinop. Indeed, until the expulsion of Russian consul in February 1807, a diplomatic war had taken place in Sinop. Both consuls followed each other tightly and try to stop each other's activities. In this way, in the early years of the 19th century Sinop lived a provincial diplomacy period that created by presence of French and Russian consuls in the city. After the Tayyar Pasha's exile to Sohum, all the balance in Anatolia had changed. In the period of Tayyar Pasa's reign in the region, Fourcade had only to try to establish good relation with Tayyar Pasa for French trade; but after 1805, Fourcade rested between a multiple powers in Sinop. In this state the turmoil reigned in Anatolia after the Tayyar Pasha's exile was a real obstacle for Fourcade's plans. Furthermore the consulate was attacked by Greek sailor under the Russian protection in 1806 when Fourcade was in Kastamonu. But aggression of 1807 was more drastic for French consulate in Sinop. Fourcade and chancellor of consulate, Bernage, were injured by Laz sailors who participated the turmoil ended Selim III' reign, debarked in Sinop in way of their homeland. The expulsion of Russian consul Konuchenco from Sinop by Ottoman-Russian War broke out in 1806 was really created a liberty atmosphere in the city. But Russian-French rapprochement and the Treaty of Tilsit reversed this atmosphere against to French in Anatolia. These new conditions that clearly seen in aggression of 1807, showed also the future of the Fourcade's mission in Sinop. Although Fourcade's Sinop consulate did not obtain significant result for French trade; his six-year consulate left us very valuable documents that exist in French foreign ministry archives in Paris and Nantes. These consular reports and detailed travel voyages accounts are very valuable sources for Southern Black Sea region at beginning of the 19th century. Fourcade, like an archaeologist and geographer travelled in his consular district and prepared detailed reports on Sinop, Kastamonu, Ladik and Amasya region. A portion of them were published; but there are also some reports are not reached until now. It is the Fourcade's archaeological activities that make the Sinop consulate worthwhile in the world of science. But beyond this, archival sources on Fourcade's six-year consulate, gives us valuable information about on the situation of Anatolia in Age of Ayans at the beginning of the 19th century, Russian impact on the Black Sea and history of Ottoman-French relations in the Black sea. This study aims to make a review on Fourcade's Sinop consulate by using resources of the French archives.

Biçer, Senol; Erkul, Zehra; Demiryilmaz, Ismail; Peker, Necla
Patient: Female, 14 Final Diagnosis: Ovarian mucinous cystadenoma Symptoms: Abdominal enlargement center dot abdominal pain center dot constipation Medication: - Clinical Procedure: Specialty: Obstetrics and Gynecology Objective: Rare disease Background: Although ovarian tumors are most commonly observed in adults, they relatively rarely occur in children. The majority of ovarian masses encountered in the premenarchal or childhood stages are non-neoplastic lesions such as benign functional cysts. Epithelial tumors account for 8-10% of all ovarian tumors and are histologically classified as mucinous or serous. The most common benign epithelial ovarian tumor is cystadenoma. Case Report: We report the case of a 14-year-old premenarchal girl with chronic abdominal pain, constipation, and abdominal enlargement. A computed tomography detected a huge left ovarian cystic tumor. A 9-kg ovarian tumor was removed surgically. Pathology showed a benign mucinous cystadenoma (MCA). Conclusions: Ovarian neoplasms in children present a diagnostic quandary, and very often the diagnoses are missed or delayed. When the diagnosis is made, a prompt and fertility- preserving surgical treatment must be performed and followed to prevent recurrence.

Yilar, Sinan; Yildirim, Omer Selim
Objective: To provide guidance in the selection of the appropriate patient for arthroscopic debridement. Materials and Methods: Ninety patients who were diagnosed with gonarthrosis according to modified American College of Rheumatology (ACR) criteria and who underwent arthroscopic debridement and meniscectomy were evaluated. Functional assessment of patients was made based on preoperative as well as 1 month and 1 year postoperative results of the Lysholm Knee Score and the Visual Analog Scale (VAS). One year postoperatively, the Tapper-Hoover Scoring System was used to calculate long-term results. Analyses were conducted using SPSS 18 software. For this study ethics committee approval was received from the ethics committee of Ataturk University Medical Studies Department Head on 08.10.2010 at the 6th meeting with regards to the document written on 16.06.2010 with number 998. Results: Differences between preoperative and 1-month and 1-year postoperative values in the Western Otorino and McMaster Universities Osteoarthrosis (WOMAC) Index, Lysholm and VAS were found to be statistically significant (p<0.001) (Table 1). According to TapperHoover results, 82.8% of patients benefited from arthroscopic debridement in the long term (Table 2). Among body mass index (BMI) groups, the WOMAC, Lysholm and VAS values of obese patients were worse than those of normal weight and underweight patients, and the difference was statistically significant (p<0.005). Late-term results of patients younger than 55 were superior to those over 55. Conclusion: In the treatment of patients with gonarthrosis, arthroscopic debridement is a good option. Patients who have a low BMI and are younger than 55 years old experience more benefit from arthroscopic debridement.

Rosa canina seeds (RCS) is considered as a low-cost and promising adsorbent in removal of metal ions; hence, in the present study, we aimed to test the adsorptive removal of Cu(II) ions from aqueous solutions by utilizing RCS in a batch process. After characterization of RCS by using several techniques, the effects of various experimental parameters such as initial pH of aqueous solution, contact time, initial Cu(II) concentration, RCS concentration, temperature, and electrolyte concentration were studied upon the adsorption process. The desorption conditions of Cu(II) ions from the loaded RCS were also evaluated. Maximum Cu(II) adsorption was found to occur at pH 6.0 and the equilibrium was established after 60 min of contact time. The adsorption isotherms were described by means of Langmuir, Freundlich, Temkin, and Dubinin Radushkevich models. The adsorption kinetics were analyzed using pseudo-first-order, pseudo-second-order, Elovich and intraparticle diffusion models and the adsorption data were well described by the pseudo-second-order model. Thermodynamic parameters such as the Gibbs free energy (ΔG), enthalpy (ΔH), and entropy (ΔS) changes were also evaluated and it has been found that the adsorption process was feasible, spontaneous, and endothermic in the temperature range of 278-313 K.

Cavdar, A.; Bingöl, S.
The concrete is the most widely used building material in Turkey. Especially reinforced concrete dominates at building sector. Because of concrete is an non-homogeneous and non-isotropic material, the strength of concrete cannot be accurately achieved at the site. To control the mechanical properties of concrete in the site, non- -destructive test methods can be used. They are useful for having no damage on concrete, however these test results sometimes gives deceptive results. In this study, two of non-destructive test methods, Schmidt hammer testing and ultrasonic pulse velocity methods were used for determining concrete compressive strength. 101 samples were poured concrete cube dimensions 150×150×150 mm3. On 28th days, firstly, the samples were applied Schmidt hammer test and ultrasonic pulse velocity test and then the compressive strength of these samples was measured by breaking in the press, destructive method. Thus, the new formulations are obtained for Schmidt hammer test and ultrasonic pulse velocity test.

Kural, Birgül; Değer, Orhan; Erem, Cihangir; Balaban Yücesan, Fulya; Aliyazicioğlu, Rezzan; Barlak, Yaşam
Background/aim: To determine the levels of adipokines (leptin, adiponectin, resistin, and visfatin) and the indices of insulin sensitivity/ resistance, and to examine the relationship among them in patients with metabolic syndrome (MetS).; Materials and methods: The study groups included 45 subjects with MetS (31 women/14 men), and 45 sex- and age-matched non-MetS healthy volunteers (31 women/14 men). The levels of adipokines were determined by enzyme-linked immunosorbent assay.; Results: The levels of leptin and visfatin were significantly higher in the MetS than in the non-MetS subjects (P < 0.01). There was no difference in adiponectin levels in subjects with and without MetS (P = 0.052). Similarly, resistin did not show any statistically significant difference. A statistically significant positive correlation of leptin with insulin levels was observed, while negative correlations of visfatin levels with age, and resistin levels with the ratio of adiponectin to leptin, were found in the MetS (P < 0.05). The combination of adipokines, insulin resistance-sensitivity parameters, and MetS criteria parameters gave more signifcant differences than a single parameter.; Conclusion: Since the parameters mentioned above might affect, interact with, and/or interfere with each other, the combinations of these parameters might give more reliable results to evaluate the insulin resistance/sensitivity in MetS patients.

Uysal, Ibrahim; Şen, A. Dündar; Ersoy, E. Yalçin; Dilek, Yildirim; Saka, Samet; Zaccarini, Federica; Escayola, Monica; Karsli, Orhan
We present the whole-rock and the mineral chemical data for upper mantle peridotites from the Harmanci{dotless}k region in NW Turkey and discuss their petrogenetic-tectonic origin. These peridotites are part of a Tethyan ophiolite belt occurring along the İzmir-Ankara-Ercincan suture zone in northern Turkey, and include depleted lherzolites and refractory harzburgites. The Al2O3 contents in orthopyroxene and clinopyroxene from the depleted lherzolite are high, and the Cr-number in the coexisting spinel is low falling within the abyssal field. However, the orthopyroxene and clinopyroxene in the harzburgites have lower Al2O3 contents for a given Cr-number of spinel, and plot within the lower end of the abyssal field. The whole-rock geochemical and the mineral chemistry data imply that the Harmanci{dotless}k peridotites formed by different degrees of partial melting (~%10-27) of the mantle. The depleted lherzolite samples have higher MREE and HREE abundances than the harzburgitic peridotites, showing convex-downward patterns. These peridotites represent up to ~16 % melting residue that formed during the initial seafloor spreading stage of the Northern Neotethys. On the other hand, the more refractory harzburgites represent residues after ~4-11 % hydrous partial melting of the previously depleted MOR mantle, which was metasomatized by slab-derived fluids during the early stages of subduction. The Harmanci{dotless}k peridotites, hence, represent the fragments of upper mantle rocks that formed during different stages of the tectonic evolution of the Tethyan oceanic lithosphere in Northern Neotethys. We infer that the multi-stage melting history of the Harmanci{dotless}k peridotites reflect the geochemically heterogeneous character of the Tethyan oceanic lithosphere currently exposed along the İzmir-Ankara-Erzincan suture zone.
