Turkey coronavirus (TCoV) is a causative agent associated with poult enteritis and mortality syndrome (PEMS) in turkeys worldwide. The disease is an acute, highly contagious enteric disease that is characterized by depression, anorexia, diarrhea, and high mortality in commercial turkey flocks. The presence of TCoV in 12 intestinal-content samples, from turkey flocks aged between 10 and 104 days and exhibiting severe enteritis, was monitored during the period of 2004 to 2006. TCoV detection was accomplished by a reverse transcriptase-polymerase chain reaction (RT-PCR) through amplification of the 3` UTR region, followed by amplification of genes 3 and 5. Molecular characterization of the viruses was done through amplification of genes 3 and 5 and showed evidence of genetic similarity between them, although they differed from sequences of other TCoVs described in the literature. In relation to gene 3, samples showed a greater relationship with chicken infectious bronchitis virus (IBV), while gene 5 showed greater identity with pheasant coronavirus (PhCoV). Our results suggest that the strategy of amplification of the 3` UTR region, followed by sequencing of genes 3 and 5, has proven to be an effective means of detecting TCoV in intestinal contents.; CNPq (Conselho Nacional de Desenvolvimento Cientifico e Tecnologico); FAPESP (Fundacao de Amparo a Pesquisa do Estado de Sao Paulo)[2006/59332-9]

O objetivo deste trabalho é analisar a geopolítica da Turquia após as transformações que alteraram o ambiente geopolítico em escala mundial. Desde a fundação da República da Turquia, Ancara tem desenvolvido relações preferenciais com o Ocidente, implementando diversas adaptações políticas, sociais e econômicas a fim de superar definitivamente o legado otomano e se ajustar às exigências do mundo ocidental. Durante a Guerra Fria, a Turquia passou a integrar a Aliança Transatlântica e serviu como elemento de contenção da União Soviética. Entretanto, o fim do mundo bipolar reduziu a importância da Turquia para a ampla estratégia de contenção americana, trazendo a necessidade de novos argumentos para manter o seu peso estratégico. Ao mesmo tempo, surgiram novas oportunidades para Ancara, especialmente quanto ao desenvolvimento de relações econômicas e culturais com os Estados independentes da ex-União Soviética. Os atentados de 11 de setembro e a reação norte-americana colocaram a Turquia novamente no centro da política americana como exemplo de compatibilidade entre o Islã e a modernidade ocidental e no combate ao terrorismo. Diversas interpretações do espaço geopolítico mundial destacam a importância da Turquia...

The degree of genetic and pathologic variation exhibited by a turkey Coronavirus (TCoV) strain was investigated after nine serial passages in 25-day-old turkey embryos obtained from wild broad-breasted bronze breeders. In spite of spleen, liver, kidneys, cloacal bursa and thymus have been collected and analysed, the main histopathological changes were only documented in the intestine sections. Microscopic lesions were characterized as mild enteritis, low degree of enterocyte vacuolization and detachment of the intestinal villous after five consecutive passages and were considered absent in the last passages. Genealogic analysis based on S1 and S2 DNA sequences suggested that Brazilian isolate might be considered as originated from TCoV strains circulating in the United States, as 100% identity with TCoV-Gl strain. Although S1 S2 sequences from each passage revealed no significant point mutations, and no correlation could be speculate between S2 nucleotide changes and pathologic features in infected embryos. This is the first demonstration of wild turkey embryos as a model for TCoV isolation and propagation.

The national blood transfusion policies have been changed significantly in recent years in Turkey. The purpose of this study was to determine the prevalence of HBV, HCV, and HIV in blood donors at the Red Crescent Center in Istanbul and to evaluate the effect of changes in the national blood transfusion policies on the prevalence of these infections. The screening results of 72695 blood donations at the Red Crescent Center in Istanbul between January and December 2007 were evaluated retrospectively. HBsAg, anti-HCV, and anti-HIV-1/2 were screened by microparticle enzyme immunoassay (MEIA) method. Samples found to be positive for anti-HIV 1/2 and anti-HCV were confirmed by Inno-Lia HCV Ab III and Inno-Lia HIV I/II Score, respectively. The seropositivity rates for HBsAg, anti-HCV, and anti-HIV-1/2 were determined as 1.76%, 0.07%, and 0.008%, respectively. Compared to the previously published data from Red Crescent Centers in Turkey, it was found that HBV and HCV seroprevalances decreased and HIV seroprevalance increased in recent years. In conclusion, we believe that the drop in HBV and HCV prevalence rates are likely multifactorial and may have resulted from more diligent donor questioning upon screening, a higher level of public awareness on viral hepatitis as well as the expansion of HBV vaccination coverage in Turkey. Another factor to contribute to the decreased prevalence of HCV stems from the use of more sensitive confirmation testing on all reactive results...

This article reports a survey on turkey astrovirus (TAstV) and turkey coronavirus (TCoV) infections with RT-PCR in 17 turkey flocks affected by acute enteritis and two apparently normal turkey flocks located in the Southeastern region of Brazil by PCR (TAstV and TCoV). Seven out of the 17 affected flocks were positive for TAstV and 14 for TCoV, with seven co-infections. In one of the two apparently normal flocks, a TAstV-TCoV co-infection was found. Although a definitive association of these agents and the signs can not be made, the implications of these findings are discussed.

Scorpion stings are common in Turkey due to its geographical location, climate and socioeconomic structure. Scorpion envenomation cases are a considerable public health problem in all regions of the country. Important health-threatening scorpions in Turkey are Androctonus crassicauda, Leiurus quinquestriatus, Mesobuthus gibbosus and M. eupeus, all of which belong to the Buthidae family. They are described to be potentially dangerous to humans. So far, there is no study about scorpion sting incidence covering all geographical regions of Turkey; therefore, in this study, we analyzed the frequency of scorpion sting cases in the country. A total of 24,261 scorpion sting cases were reported during 2005. Most of which (about 80%) occurred in the Southeastern Anatolia (30.4%), Mediterranean Sea (24.9%) and Aegean regions (23.5%), where medically important scorpion species are found. The sting cases mostly occurred during the summer period. Our results suggest that scorpion stings are an important problem in Turkey. This simple descriptive study will help develop interventions to prevent scorpion stings, which should take local sting cases into consideration.

Scorpion stings constitute a common type of accident in Turkey due to the geographic location, climate and socioeconomic structure of this country. Moreover, envenomation cases are considered a public health problem throughout Turkey. Based on data in the literature, the main clinical features of scorpion envenomations are defined as systemic manifestations including sweating, hypertension and vomiting, and among prominent causes of death are cardiorespiratory manifestations, toxic myocarditis and pulmonary edema. The most important health-threatening scorpions found in Turkey are: Androctonus crassicauda, Leiurus quinquestriatus, Mesobuthus gibbosus and Mesobuthus eupeus, all of which belong to the Buthidae family. This study indicates that there is no data related to venom toxicity and in vivo effects of other scorpions found in Turkey - such as Mesobuthus caucasicus, Mesobuthus nigrocinctus and Hottentotta saulcyi - and that further research should be performed to determine their health effects.

The venom of poisonous snakes comprises a complex mixture of several proteins with other less significant constituents, resulting in principles capable of changing viable tissues. The hemotoxic factor is the main responsible for necrosis and tissue sloughing. Envenomations are common in rural areas of Turkey caused by snake species that present hepatotoxic venom, which causes local swelling, ecchymosis and alterations in blood profile. The epidemiological and clinical findings of snake envenomations in Turkey were evaluated based on data recorded by the National Poison Information Center (NPIC) between 1995 and 2004, in a total of 550 snakebite cases. The month of peak incidence was June (24.3%) while most incidents occurred in Marmara, Central Anatolia and Black Sea regions of Turkey. The victims were mainly adults (54.1%). Hospitalized patients displayed clinical signs of local (75.2%) and systemic effects (24.7%). Local clinical symptoms comprised edema, pain, hyperemia, numbness and ecchymosis, while systemic clinical symptoms included nausea, vomiting, hypotension, tachycardia, dyspnea, dry mouth, paresthesia, generalized edema, cyanosis and compartment syndrome. Occasionally, convulsions, confusion, loss of consciousness, hyperthermia...

The dissertation documented the degree of Turkey’s involvement in the promotion of democracy in the Arab Middle East (ME). Initially, I investigated why and under what conditions Turkey promotes democracy in the ME, and then I explained strategies through which Turkey promotes democracy in the region. I applied the neo-classical realist theoretical framework and a mixed methodology in the research, and I provided evidence from two sources: face-to-face interviews with the Turkish and foreign officials and common citizens, and the statistical data from institutions, such as the OECD, Turkish Statistical Institute, and World Bank. My research indicates that Turkey promotes democracy through seven channels. These channels are official development assistance (ODA), mentoring, demonstrative effect, normative pressure, conditionality, military power, enlargement, and civil society organizations. Turkey promotes democracy in the ME for three substantial reasons: first, to advance its security and economic interests; second, to improve the political, social, and economic conditions of people living in the region; and third, to create long-term regional stability, crucial for cooperation in economic and security realms. I attempted to engage in debates with two distinct...

Approved for public release, distribution is unlimited; Since 1963 Turkey has been struggling to join the European Union (EU) . Despite strong Turkish aspirations, it appears unlikely that Turkey will be accepted as an EU member in the near future due to Turkey's shortcomings in its political, economic and social structure. Applications submitted prior to December 1999, were rejected by the EU Commission on the basis of poor democracy, human rights abuses, restrictions on political and cultural rights, a high level of influence of the Turkish military in political affairs, weak economy, and disputes with Greece and the Cyprus problem. The EU has certain criteria for membership: a functioning democracy, respect for rule of law, protection of minority and human rights, functioning market economy and settlement of disputes with other member states prior to accession. Turkey is seeking an immediate EU membership to improve economy and democratization, and take an undisputable place inside the European order and civilization. To this end, Turkey has to adopt the necessary reforms and regulations that will help strengthen democracy, economy and social and cultural rights in Turkey. However, Turkey's present domestic infrastructure does not provide a suitable situation to commence key radical political reforms in the immediate future.; http://www.archive.org/details/turkeyeuropeanun00aydi; Lieutenant...

For Turkey, Europe was the model for modernization since the era of Kemal Ataturk. Turkey's relations with Europe started with the Ankara agreement and the opening of the custom union. Since then, the country has strived for integration with the community. The Commission rejected Turkey's application in 1989 while stating for the first time that political reasons affected this decision over concerns about the Cyprus issue. The integration of new members highlighted the shift of Europe towards political considerations. Turkey was rejected again as a candidate at the Luxemburg summit. The following Helsinki summit accepted the candidacy for Turkey but now the country must comply with the political criteria. Turkey has made great progress towards integration. However, the demands imply that Turkey must make strong decisions that might contradict the country's long standing powers' politic approach. Moreover, the criteria raise security concerns in a country were security is an aspect of its psychology. The implementation of a such strong decision needs a calmer democratic environment. Turkey's further impediment results from such an absence. Thus, Turkey's real impediment is democratic deficiency. Therefore, Turkey needs a little more time to better align itself with the democratic values of the European standard before its integration...

A ship, which has landed in the harbor of Smyrna, Turkey, has a cargo of wood and is selling it by weight. Many onlookers are around the ship. Smyrna is located in part of the city of İzmir, Turkey. Original resource is a black and white photograph.; In 1908, the Rice Institute Board of Trustees sent their newly chosen President, Edgar Odell Lovett, on a world tour seeking out the best aspects of the leading colleges and universities. Dr. and Mrs. Lovett traveled in the company of their secretary, Mr. Carrington Weems, who took these photos to document their travels. They are images of places, more so than people. Dr. and Mrs. Lovett themselves are generally not featured. Each image has an image number that reflects the order in which it was taken on the trip, from number 1 (beginning in Canada and going east around the world) through number 338 (returning to the U.S. through California and ending in Texas), ranging in date from 1908-1909. The names of each image were recorded by Carrington Weems, with the only exception being a county name added in parenthesis when the place name was not present in Weems' original title.

Examining Board: Professor Donatella della Porta, European University Institute (Supervisor) Professor László Bruszt, European University Institute Professor John D. McCarthy, Penn State University Professor Ziya Onis, Koc University.; Defence date: 18 December 2013; This thesis is about the police and the control of public protests in Turkey. Despite its centrality to state power, the police have never become a mainstream subject of political sociology. Particularly on a stage where governments perform state power in the face of societal dissent, the police are not bit players but lead actors who demystify curiously about the political foundations of a regime. My dissertation focuses on contemporary manifestations of protest policing in a geography where democratization incorporated previously discredited actors into the political centre while the strong hand of the state advanced in modern technologies of law enforcement. I specifically interrogate how the transformation of the police after 1980 and more precisely since the end of the 1990s reflects on the policing of public protests, and how this transformation resonates with the patterns of protest in the country. I am also empirically interested in the application of this process on contentious gatherings of different origin; namely on labour...

This thesis will argue that one of the main challenges Alevis experience in Turkey is the lack of adequate historical credit afforded to them within Modern Turkish society. Though Alevis have a much older history than the Republic of Turkey, having occupied the region for centuries before the inception the modern Turkish nation-state, they still have a very specific relationship with the development of the secular Kemalist-Turkish identity. In fact, Alevis began to develop a novel and unique political identity, which embraced secularism in spite of deeply rooted religious convictions, during Turkey's National transition from the late Ottoman Empire (early 1900s) to the early multi-party era (late 1950s). Existing scholarship on Alevi identity often exclusively focuses on how they were perceived as a religious group during the Ottoman Era or on their increasingly marginalized political identity after the 1970s. However, this thesis will argue that these approaches fail to appreciate the "transition period" of Alevi identity, and how the transformation from being considered a strictly religious/ethnic identity within the Ottoman Empire to becoming viewed as vocal and political advocates of secularism from the early Republic is crucial to understanding contemporary Alevi identity. It will argue that past research has not paid enough attention to this transition...

The Turkish economy was hit hard by the global economic crisis, but recovered fast and strong. The economy had already started to slow down in 2007, but the global financial events of late 2008 led to a sharp contraction starting in the last quarter of 2008 until growth resumed in the last quarter of 2009. The recovery was rapid, with growth reaching 9 percent in 2010 and 8.5 percent in 2011. This study looks at how the labor market fared during the recent downturn and recovery and informs policies to manage labor markets through the economic cycle and address the jobs challenge in Turkey. The study investigates: 1) pre-crisis labor market trends and the structural jobs challenge in Turkey; 2) aggregate and distributional impacts of the recent crisis, and subsequent recovery, on the labor market; and 3) recent policy measures and existing labor market institutions in the context of observed labor market outcomes. Finally, the study links policies to manage labor markets through the cycle with measures to address the longer term...

Ce mémoire analyse trois réformes majeures de politique sociale en Turquie, en deux domaines: emploi et sécurité social. En utilisant l'approche "Usage de l'Europe", ce mémoire developpe une analyse empirique et apporte une explication théorique de ces changements qui ont été introduits au cours du processus d'adhésion de la Turquie à l'Union européenne. "Les usages de l'Europe" est une approche d'européanisation qui se concentre sur le rôle des acteurs domestiques, au sein des États membres et candidats, ainsi que de leur utilisation des ressources de l'Union européenne. Les études de cas utilisées dans cette thèse démontrent l'introduction de changements au niveau de l'État-providence; ainsi, l'approche originelle est suppléée par des concepts provenant de la littérature sur la politique partisane, les institutions formelles et l'héritage des politiques. Cette recherche utilise la méthode de l'analyse de processus pour suivre la réforme des règlements du travail par la voie de reconstitution des droits individuels des travailleurs et de l'Agence d'emploi en Turquie jusqu'en 2003, ainsi que la transformation du système de sécurité sociale en 2008. Ces trois réformes représentent des changements majeurs tant sur le plan institutionnel que politique en Turquie depuis 2001. Afin de comprendre "les usages de l'Europe" dans ces réformes politiques...

The European Union, as a regional actor and an example of stability and well-being, has embraced a set of principles it has stood for and which constitute its own identity. The diffusion of these values among third countries is one of the objectives of EU’s External Policy. Democracy can be found among the principles that are sought to be exported through comprehensive and complex strategies within different frameworks, such as neighbourhood relations, trade partnerships and the accession process. Focusing on the latter, candidates are object of an intensive process of Europeanisation that operates through different mechanisms like socialisation and conditionality. Turkey, on the other side, has decided to apply for full membership several decades ago and, ever since, it has been pressured to Europeanise, which includes improving its unstable democracy. This case, however, is different from all other previous enlargements; for its special socio-cultural and civilisational features, Turkey constitutes a more complex novelty for the European Union. Therefore, this thesis aims to study the influence of the European Union on the democratisation process of Turkey, focusing on the period ranging between 1999, the year the European Council recognised Turkey’s candidacy status...

Bowman, Jacob L.; With the increase popularity in turkey hunting in the State of Delaware and the increase in turkey numbers since 1984, the state of Delaware and the university of Delaware started a project to investigate the reproduction success of Eastern wild turkey hens (Melagris gallopavo silvestris). I captured 106 turkeys using rocket nets and placed backpack transmitters on 76 hens in December 2009-March 2010 and December 2010-March 2011. I classified each bird as adult or juvenile, marked them with unique bands and placed transmitters on hens weighing >3.4 kg (>7.5lbs). To estimate survival, I took locations from fixed ground telemetry stations 3-7 times a week. The estimated survival rate of adult hens in 2010 was 0.47(SE=0.09), which was 0.21 less than the 2011 survival rate of 0.68 (SE=0.07; X 2 1 = 2.82, P = 0.093). Predation accounted for 87.1% (n = 27) of the moralities with foxes being attributed to most predation events (85.2%, n =23). Most mortalities (61.3%, n=19) occurred during the nesting season (15 April-15 June). The variation in annual survival justifies the need for continued monitoring of this population. Nest success has been found to be an important factor in overall population success. Nesting habitat variables and landscape variables have been studied before with a wide range of what hens select for a nest and what habitat variables effect nest success. I placed 76 transmitters on hens...
