- MakaleYalnız künye2011Sadâret’ten başvekâlet’e sadrazamlık
Satış, İhsan
19. yüzyıla kadar, padişaha karşı ülke yönetiminden, tebaanın güvenliğinden, dış politikadan ve savaşlardan sorumlu olan sadrazam, II. Mahmut’un merkeziyetçi reformları neticesinde yetkileri azalmaya başlamıştır. II. Mahmut, sadrazama bütün vekillerin başı olmak üzere başvekil sanını vererek, yetkilerini nezaretler arasında dağıtmıştır. Avrupa’ya ayak uydurma sürecinde sadrazamlık hızla kurumlaşırken asıl işlevi de siyaseti belirlemek ve uygulamak olmuştur. Lakin II. Mahmut’un ölümünden sonra Sultan Abdülmecit, Koca Hüsrev Paşa’yı sadrazam tayiniyle başvekil unvanı kaldırılarak tekrar sadrazam tabiri kullanılmaya başlanmıştır. Bu makalede, 19. yüzyılın ilk yarısında sadrazamlık kurumundaki değişimler ele alınmıştır.

- MakaleYalnız künye2011"Mağdur" milliyetçilik kürt siyasetinin "demokratik" zaafiyeti ve ulus açmazı
Özcan, Ali Kemal
Ulus-devletin kendisiyle birlikte insanlığa bulaştırdığı "milliyetçilik" (nationalism), akademik tartışmaların en karmaşık konularının başında gelir denebilir. Bu konuda kavramsal bir "anarşi"1 veya bir "terminolojik kaos"2 süregelmektedir. Türkiye 'de ise bu biraz daha daraltılmış, aynı zamanda yavan bir hal almıştır: neredeyse tamamen "vatanseverlik" kavramı yerine kullanılmaktadır. Hâlbuki halk dilinde kendi etnisitesini ve yerel değerlerini sevmeye refere eden ve akademik terminolojiye de sorunsuz oturabilecek yeterli kelime/kavram mevcuttur. Örneğin vatanseverlik, vatanperverlik, yurtseverlik veya milletseverlik, halkseverlik gibi. İngilizce ve birçok diğer Avrupa dillerinde de bu anlamda "patriotism " veya Latince patrie köklü benzer kavramlar vardır. Bu çalışma, birbirine çok yönlü olarak karıştırılmış olan milliyetçilik ile vatanseverlik kavramlarını ayrıştırmanın zemini üzerinde, Kürt milliyetçiliğinin "ulus" açmazını ve "demokratik" olma kompleksini açmaya çalışarak, Türkiye 'nin son otuz yılının temel sorunu olan Kürt meselesinin aslında Türkiye 'nin bir fırsatı olabileceğini tartışmaktadır.

Tuna, Ş. Gürçağ; Doğan, Ali Ekber
Küçük bir kent olmasına rağmen Tunceli, daha geniş bir bölgenin eski adı olarak da Dersim her daim siyasal gündemin bir konusu olagelmiştir. Son yıllarda bu yörenin sosyal-siyasal-kültürel yapısına ve tarihine ilişkin artan bir akademik ilgi söz konusu olsa da, burada bugün geçerli olan sosyal ve ekonomik ilişkilerin analizi pek ilgi gören konular değildir. Çalışmamız, bu eksikliğin emek süreçlerinin iki önemli boyutunu oluşturan çalışma/istihdam biçimleri ve işgücü piyasasının yapısı bağlamlarının yanında işsizlik, proleterleşme, zorunlu göçün etkisi gibi olgularla giderilmesine dönük bir çabanın ürünüdür. Bu analizi yaparken aynı zamanda, Tunceli'de gündelik yaşamda sıklıkla dile getirilen Tuncelilerin/Dersimlilerin çalışmayı sevmediği, tembel olduğu savının geçerliliğini ve anlamını da tartışmak istedik. Tembelliğin bir toplum kesimi veya insan topluluğunu tanımlayan özelliklerden biri olarak yaygın biçimde kullanılmasına, "tembelliğin kültürelleştirilmesi" diyebiliriz. Gerek Türkiye gerekse dünyanın pek çok yerinde kapitalizmin kendi suretinde bir dünya yaratmaya başladığı tarihlerden bu yana karşımıza daha sık biçimde çıkan tembelliğin kültürelleşmesi dediğimiz bu tavrı eleştirel yaklaşımla, dünya-tarihselliği içinde değerlendirmenin en doğru yol olduğunu düşünüyoruz.

In present study, the proximate composition, fatty acid profile and mineral content of wild brown trout living in Munzur river (Tunceli/Turkey) were investigated. The average level of protein, lipid, moisture and ash content of muscle of the wild brown trout was calculated to be 17.48, 2.3, 77.8 and 1.5 %, respectively. Thirty fatty acids were identified in this study. Identification of the fatty acid was carried out with gas chromatography-mass spectrometry (GC-MS). The total polyunsaturated fatty acids (PUPA) were found the highest fatty acid followed by that of saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA). Docosahexaenoic acid (DHA, C22:6n3) and eicosapentaenoic acid (EPA, C20:5n3), linolenic acid (LNA, C18:3n3) and linoleic acid (LA, C18:2n6) were found to be predominant fatty acids in PUFAs with the percentages of 11.25, 6.82, 6.30 and 4.88, respectively. The ratio of n3/n6 and DHA /EPA was calculated to be 4.55 and 1.65, respectively. Twelve elements were determined in this study. Determination of elements was performed with ICP-AES. P and K were the predominant element among the minerals analyzed and calculated to be 1305.56-2967.06 and 1908.68-1220.10 mg kg(-1) in muscle-skin of the wild brown trout, respectively.

Kaplan, O.; Yildirim, N. C.; Yildirim, N.; Cimen, M.
In the higher organisms, the intake of trace elements occurs mainly through the respiratory system or through the food chain. Particularly, many dangerous elements or compounds, such as metals accumulate along the food chain. In this way, the food chain becomes the main gateway for persistent toxicants to enter higher organisms. Furthermore, these toxic elements generally have an anthropogenic origin and thus their concentrations in the environment grow with the increase of urban, agricultural and industrial emissions. With increasing environmental pollution, a toxic metal exposure assessment study is necessary. Toxic elements are not metabolized at all. Some metals irreversibly are bound to body tissues, e.g., lead to bone or cadmium to kidneys. This review updates the information on carry-over of toxic substances from feed to food of animal origin (meat, organs, milk and eggs). The control of environmental contaminants that may cause residues in food of animal origin is sometimes quite difficult and expensive and is addressed with special attention in this review.

Aim of this study was to determine the extent of pollution in the Munzur River in Turkey was determined. The antioxidant (reduced glutathione (GSH), glutathione peroxidase (GSH-Px) catalase (CAT)) and the oxidant (MDA) status of hepatopancreas, gills, muscle, heart and kidney tissues of C. trutta were chosen as bioindicators. The fish samples were caught from contaminated (Station I) and uncontaminated (Station II) stations in Munzur River during April 2010. GSH levels were lower in gill, muscle and heart of the C. trutta collected at the contaminated station (p<0.05). The MDA levels were significantly higher in gill, muscle, kidney and heart of the C. trutta from the contaminated station (p<0.05). The CAT activity was significantly increased in the gill tissue at the contaminated station (p<0.05). GSH-Px activity was significantly decreased (p<0.05) in gill, muscle, kidney and heart tissues samples from C. trutta collected at the contaminated station compared to those collected from the uncontaminated station. Overall, the results demonstrate that alteration in the antioxidant enzymes, glutathione system and induction of lipid peroxidation reflects the presence of pollution, which may cause oxidative stress in the C. trutta from Munzur River. The results provide evidence those enzymatic and non-enzymatic biomarkers of oxidative stress.

This study was carried out to determine whether bank employees' burnout levels and satisfaction of life differentiate significantly according to certain variables and to reveal the relationship between them. Bank employees' satisfaction of life was measured by using Satisfaction of Life Scale and their burnout levels by Maslach Burnout Inventory. The main scope of research comprised of bank employees working in cities of Sivas and Tunceli. A total of 264 bank employees participated in this research. As a result of this research, it appeared that participants' satisfaction of life levels were generally high. When the mean scores obtained by them from burnout scale were scrutinized, it was observed that sample's emotional burnout and depersonalization levels were high and the personal accomplishment levels were medium. It was concluded in the research that there was a poor relationship between burnout and satisfaction of life. In addition, certain differences were discovered in each of the three sub dimensions of burnout levels of bank employees, in terms of variables such as gender, age, marital status, education and length of service.

Yildirim, N. C.; Danabas, D.; Ergin, C.
The potential utility of biomarkers for monitoring both environmental quality and the health of organisms inhabiting polluted ecosystems has received increasing attention during the recent years. In this study. it was aimed to investigate the possible effect of pollution on biochemical parameters of Capoeta trutta captured in two environments with different levels of pollution in Munzur River, Tunceli, Turkey. One of them, hereby named reference site, there is no sewage discharge. Other side is denominated as polluted site is characterized by discharge of domestic sewage. Levels of amylase, alkaline phosphatase, lactate dehydrogenase, high-density lipoprotein cholesterol, cholesterol, albumin, total protein, direct bilirubin, total bilirubin, gamma-glutamyl tranferase, aspartate aminotransferase, alanine aminotransferase, urea, creatinine, glucose, triglycerides and uric acid were checked in blood samples. Plasma biochemical changes showed significantly differences between reference and polluted sites in alkaline phosphatase, lactate dehydrogenase, high-density lipoprotein cholesterol, cholesterol, alanine aminotransferase and glucose values. These results indicate that both domestic waste water and agricultural activities can alter the serum biochemical contents of Copeata trutta fish in Munzur River. Continuous production of pollutants resulting in impaired ability to respond to different environment stress factors and diseases. Present groups of researchers suggest that pollution levels should be monitored regularly.

Uslu, Gulsad; Gültekin, Gulden; Tanyol, Mehtap
The bioaccumulation of copper (II) and cadmium (II) ions by viable P. putida was studied as a function of initial pH, temperature, initial glucose and initial metal ion concentration. Optimum pH value for maximum metal ion accumulation was determined to be 3.0 +/- 0.5 and 4.5 +/- 0.5 at 25 and 30 degrees C for each metal ion, respectively. At a constant glucose concentration, although the increase in initial copper (II) and cadmium (II) ion concentration up to approximately 25 mg L-1 increased bioaccumulation capacity of P. putida for both, all metal ion concentrations tested inhibited the growth of P. putida. High microbial growth and copper (II) and cadmium (II) accumulation yields were found at low initial metal ion concentrations. The cell and bioaccumulated metal ion concentrations and uptake yields in-creased with increasing glucose concentration up to 10 g L-1 at a constant metal ion level for each of the metal ions. Although both metal ions caused on inhibition effect on the growth of the microorganism, P. putida was capable of removing copper (II) and cadmium (II) with maximum specific uptake of 58.42 mg g-(1) and 34.65 mg g(-1) at 25 mg L-1 initial copper(II) and cadmium(II) level, respectively. The results also indicated that, P. putida was more efficient in accumulating larger amounts of cadmium (II) than copper (II) ions.
