Generation of feasible integer solutions on a massively parallel computer using the feasibility pump
No full textUtku Koç (MEF Author)We present an approach to parallelize generation of feasible mixed integer solutions of mixed integer linear programs in distributed memory high performance computing environments. This approach combines a parallel framework with feasibility pump (FP) as the rounding heuristic. It runs multiple FP instances with different starting solutions concurrently, while allowing them to share information. Our computational results suggest that the improvement resulting from parallelization using our approach is statistically significant. (C) 2017 Elsevier B.V.

Abuse of the right to access ICSID arbitration
No full textIn the last decade, the Tribunals of the International Centre for the Settlement of Investment Disputes (ICSID) have discussed the adoption of a new standard in assessing the jurisdictional requirements of the Convention on the Settlement of Investment Disputes between States and Nationals of Other States, in order to preserve the integrity of their own process, by introducing the general principle of the abuse of rights into the initiation of the ICSID arbitration process. This well-known principle of international law, along with other similar concepts such as good faith and abuse of process, has begun to play an important role at the jurisdictional stage of ICSID proceedings, largely due to the widely adopted practice of treaty shopping by investors who restructure their investments in order to gain access to the jurisdiction of ICSID tribunals. Although the exact parameters of the principle are not yet established, the practices of ICSID tribunals provide a useful road map for future cases. © The Author 2014.

Dünya-sistemine entegrasyon ve islamcı hareketlerin metot seçimi arasındaki ilişki: Türkiye örneği
No full textThis study aims to analyze Islamism from economic and political perspective. World-systems analysis is the doctrinal basis of the study. The main argument of the thesis is that there is a relationship between the way countries integrate into capitalism and the development of Islamist movements in those countries. In the first part of the study, world-systems analysis is explained with its basic lines. In addition, the Annales school, which constitutes the understanding of history in the study, is also explained. In the second part, the Ottoman social structure is analyzed from the economic and political perspective. In the second part, The Ottoman Empire is analyzed in four periods as foundation period, classical period, âyans periods and the modern period. In the third part, the types of regions which integrated into the world-economy are explained. Three types of zones have been identified: peripherical zones, colonial zones and dark zones. It is claimed that Islamism developing in a region is different because the relationship between each type of region and the world-economy is different. Islamist movements in India, Saudi Arabia and Egypt have been examined in this respect. In the fourth part, the development of Ottoman Islamism is examined. The effects on Islamism of the Ottoman integration to the world-economy as a periphery are analyzed. As a result, the thesis tries to understand Islamism from the perspective of world-systems analysis. And Ottoman Islamism is the main subject.Bu çalışma, İslamcılığı ekonomi-politik açıdan analiz etmeyi amaçlamaktadır. Dünya-sistemleri analizi çalışmanın doktriner temelini oluşturmaktadır. Tezin en temel argümanı, ülkelerin kapitalizme eklemlenme biçimleri ile o ülkelerdeki İslamcı hareketlerin gelişimi arasında ilişki olduğudur. Çalışmanın ilk bölümünde temel hatlarıyla dünya-sistemleri analizi anlatılmaktadır. Bunun yanında çalışmadaki tarih anlayışını oluşturan Annales ekolü de izah edilmektedir. Ardından ikinci bölümde Osmanlı toplumsal yapısı ekonomi-politik bakış açısıyla analiz edilmektedir. Burada Osmanlı Devleti; kuruluş dönemi, klasik dönem, âyanlar dönemi ve modern dönem olarak ele alınmaktadır. Üçüncü bölümde ise dünya-ekonomiye eklemlenen bölge tipleri izah edilmektedir. Bu açıdan üç bölge tipi tespit edilmiştir: çevre bölgeler, sömürge bölgeler ve karanlık bölgeler. Her bir bölge tipinin dünya-ekonomi ile girdiği ilişki farklı olduğundan o bölgede gelişen İslamcılığın da farklılaştığı iddia edilmektedir. Hindistan, Suudi Arabistan ve Mısır ülkelerinde gelişen İslamcı hareketler bu açıdan incelenmiştir. Dördüncü bölümde ise Osmanlı İslamcılığının gelişimi incelenmektedir. Osmanlı’nın dünya-ekonomiye bir çevre ülke olarak eklemlenmesinin İslamcılık üzerine olan etkileri analiz edilmektedir. Sonuç olarak çalışma, dünya-sistemleri analizi perspektifinden İslamcılığı anlamaya gayret etmektedir. Osmanlı İslamcılığı da üzerinde durulan esas konudur. Çalışma, Osmanlı İslamcılığını daha önce değerlendirilmemiş bir açıdan anlatmaya gayret etmektedir
Unlocking the insights: data-analytic examinations of social signals in organizational practices
No full textUsing analytics to understand social data is an emerging research field across different academic disciplines including Information Systems. Information Systems (IS) discipline places the social media-related research at the intersection of people, organizations, and technology. While the recent focus of design science utilizes advanced data mining methods to develop decision-aiding frameworks and extend organizational boundaries by designing novel artifacts; the behavioral focus develops and tests theories that elucidate behaviors at the individual or organizational levels. This thesis comprises three essays aiming to contribute to IS research by both leveraging from the two foundational principles of IS -behavioral science and design science- and applying advanced analytics to further understand the executive, stakeholder, and brand relations. These implementations allow us to elegantly capture several important features of the social signals that have been employed in online networking platforms. In the first two chapters, social signals are examined as internal and external associations of the executives’ career outcomes. The third chapter investigates the social signals from brands’ perspectives. While the first two chapters highlight and examine the relationships of several constructs, the main emphasis of the third chapter lies on designing a valuable information systems tool to complement the theoretical studies and enhance the practical implementations.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2019-05-01The student, Utku Pamuksuz, accepted the attached license on 2017-04-20 at 11:08.The student, Utku Pamuksuz, submitted this Dissertation for approval on 2017-04-20 at 11:19.This Dissertation was approved for publication on 2017-04-21 at 09:23.DSpace SAF Submission Ingestion Package generated from Vireo submission #10931 on 2017-08-10 at 14:32:20Made available in DSpace on 2017-08-10T19:52:18Z (GMT).

Bunda iletişim konusunda her türlü teknolojinin hızla gelişmesinin de büyük payı bulunmaktadır. Görüntü, görsel dünya, hızla tüm sanat dallarını, toplumsal yaşayışı ve kültürleri etkilemiştir. Edebiyat ise görselliği zihinsel imgelem sürecinde, yazı aracılığıyla işletir. Roman imgeye ve kurguya dayalı, insanı konu alan bir edebiyat ürünüdür. Bu çalışma ile gündelik yaşamda değişen davranış kalıplarının, imajların romanda yazarın imgeleriyle yeniden yaratılması ve okuyucunun kendi imgelerini de katarak eseri alımlaması ve çoğaltma sürecinde, romandaki görsellik incelenmiştir. Çalışmaya örneklem olarak da iki farklı dönemin romanları ele alınmıştır. Bu da Türk edebiyatının ilk roman ürünlerinin verildiği ve çağdaş edebiyata geçiş süreçlerinin yaşandığı Tanzimat edebiyatının en önemli eserlerinden Recaizade Mahmut Ekrem'in Araba Sevdası romanı ile, 2000'li yıllarda yazılmış ve popülerlik kazanmış Murathan Mungan'ın Yüksek Topuklar adlı romanı arasındaki anlatım dilinin görselliğinin ne boyutlarda değiştiğinin bir göstergesi olacaktır Name and Surname:Ayşegül Utku Günaydın Field:Communication Science Programme:Communication Science Supervisor:Proffessor Nurçay Türkoğlu Degree Awarded and Date:Master - July 2003 Novel, İmage, Visuality ABSTRACT THE VISUALITY IN THE NOVEL AS A CONTEMPORARY EXPRESSION LANGUAGE (METHOD): FROM ARABA SEVDASI TO YÜKSEK TOPUKLAR The impacts of visual culture and visuality can be seen in almost every aspect of life. The technological innovations in the field of communication play a crucial role in this fact. The image and the visual world has been effecting all kinds of art, social life and culture. On the other hand literature makes use of visuality in the process of imagination through the use of writing. The novel is a literary product which focuses on human being and depends on imagination. In this study the visuality in the novel is examined through the analysis of the recreation of changing behaviors and images by the author together with the reader's perception and augmentation process. For this purpose two novels from two different periods has been selected, namely Araba Sevdası by Recaizade Mahmut Ekrem and Yüksek Topuklar by Murathan Mungan. The first one is counted for being one of the earliest works in the Turkish Literature representing both the characteristics of the transition to the contemporary literature and the Tanzimat period. The latter is dating from 2000's and a popular one which constitutes a good example for how the dimension of the visuality of the expression language (method) has changed
AUTHOR IDENTIFICATION IN SHORT TEXTS: A METHODOLOGICAL PROPOSAL FOR TWITTER
No full textVerili bir metnin yazarını tespit etmek ve birkaç metnin arasından yazarı aynı olanları bulmak, adli dilbilimin önemli uygulama alanlarından biridir. Günümüze dek yapılan çalışmaların çoğu, gazetelerin köşe yazıları gibi uzun ve nispeten fazla miktarda dilsel veri içeren bütünce ile gerçekleştirildiğinden, kısa metinlerde yazar tanımaya ilişkin herhangi bir yöntem sunmamaktadır. Zira adli dilbilim kapsamında yapılan çalışmalarda, incelemelere konu edilen metinler oldukça kısadır. Bununla birlikte, mikro-blog siteleri de dâhil olmak üzere, sosyal medya üzerinde yapılan paylaşımlar da çoğu kez ceza veya hukuk davalarının konusu olabilmektedir. Dolayısıyla kısa metinler üzerinde yazar tanımaya ilişkin birtakım yöntem ve yaklaşımlara ihtiyaç duyulmaktadır. Bu çalışma, özellikle karakter kısıtı gözetilerek seçilen Twitter adlı mikro-blog sitesinden toplanan çeşitli metinlerin; dilbilgisi, noktalama, sözcük ve bağlam özellikleri kullanılarak yazarlarının tespitine ilişkin bir yöntem önermeyi amaçlamaktadır. Ayırt edici olduğu veya olabileceği görülen özellikler paylaşılmakta ve çoğunlukla bütünceye göre biçimlendirilmesi gereken yöntemler, genel başlıklarıyla birlikte sunulmaktadır.Determining a given text’s author and finding the texts whose authors are the same, through several texts is one of the most important application fields of forensic linguistics. Most of the studies, which are done up to the present, were conducted along with a long corpus, which also consists of relatively more linguistic data such as newspaper articles. Thus, they don’t suggest a method in terms of author identification of short texts. Yet, in forensic linguistic studies, the entreated texts are quite short. However, social media entries including the micro-blogs can be subject to criminal or law cases several times. Accordingly, there’s a need for some methods and aspects related to author identification. This study aims to suggest a method to determine authors by using grammar, punctuation, lexis and context features of texts, which were collected from the micro-blog named Twitter, with a special regard to its character constraint. The features, which are seen to be or may be distinctive, are shared and the methods, which mostly need to be formatted related to the corpus, are presented along with their general titles

No full textThe main purpose of this study is to investigate CSR activities of national, foreign and private banks listed in Borsa
İstanbul (BIST) 30 Index in Turkey and reveal the differences between these banks in terms of the fulfilment of
their social responsibilities. Within this scope; the concept of CSR, CSR definitions, the main reasons of CSR
activities and four dimensions of CSR constitute the conceptual framework of the study. On the other hand;
shareholder theory, stakeholder theory and institutional theory establish the theoretical framework of this study.
In parallel with the study purpose, CSR practises of three different banks listed in BIST 30 Index as of the second
quarter of year 2016 were analyzed. The relevant data were acquired from archival sources such as corporate
governance compliance reports, annual sustainability reports and official company websites. The qualitative
research was considered to be useful method to clarify the differences in social responsibility practises. For this
reason, content analysis as a qualitative research method was used in order to investigate CSR activities of banks.
Research findings reveal that there are not significant differences between Isbank (private bank) and VakıfBank
(national bank) with regard to the fulfilment of their social responsibilities. On the other side, Garanti Bank (foreign
bank) implements more CSR practises in comparison with other banks. This dissimilarity is also observed among
CSR headings. All in all, a great majority of CSR activities are carried out about environmental conservation and

Bu kapsamda; KSS kavramı, KSS tanımları, KSS faaliyetlerinin başlıca nedenleri ve KSS’nin dört boyutu çalışmanın kavramsal çerçevesini teşkil etmektedir. Diğer taraftan; hissedar kuramı, paydaş kuramı ve kuramsal kuram ise çalışmanın teorik altyapısını oluşturmaktadır. Çalışmanın amacı doğrultusunda, 2016 yılının ikinci çeyreğinde BIST 30 Endeksi’ndeki üç farklı bankanın KSS faaliyetleri incelenmiştir. İlgili veri şirketlerin; kurumsal yönetim uyum raporları, yıllık sürdürülebilirlik raporları ve resmi internet siteleri gibi arşivsel kaynaklardan elde edilmiştir. Sosyal sorumluluk uygulamalarındaki farklılıkları açıklığa kavuşturmak için nitel araştırma metodunun uygulanması düşünülmüştür. Bu nedenle, bankaların kurumsal sosyal sorumluluk uygulamalarındaki farklılıkları araştırmak amacıyla nitel araştırma yöntemlerinden içerik analizi kullanılmıştır. Araştırma sonuçları, sosyal sorumlukların yerine getirilmesi bakımından İş Bankası (özel banka) ile Vakıfbank (kamu bankası) arasında önemli bir fark olmadığını göstermiştir. Öte yandan, bu bankalara nazaran Garanti Bankası (yabancı banka) daha fazla KSS uygulaması yürütmektedir. Bu farklılık, KSS başlıkları arasında da gözlemlenmiştir. Genel olarak değerlendirildiğinde, KSS faaliyetlerinin büyük çoğunluğunun çevre koruma ve paydaşlar hakkında gerçekleştirildiği görülmüştür
