Recent advances in neuroimaging technologies have rendered multimodal analysis of operators’ cognitive processes in complex task settings and environments increasingly more practical. In this exploratory study, we utilized optical brain imaging and mobile eye tracking technologies to investigate the behavioral and neurophysiological differences among expert and novice operators while they operated a human-machine interface in normal and adverse conditions. In congruence with related work, we observed that experts tended to have lower prefrontal oxygenation and exhibit gaze patterns that are better (...) aligned with the optimal task sequence with shorter fixation durations as compared to novices. These trends reached statistical significance only in the adverse condition where the operators were prompted with an unexpected error message. Comparisons between hemodynamic and gaze measures before and after the error message indicated that experts’ neurophysiological response to the error involved a systematic increase in bilateral dorsolateral prefrontal cortex (dlPFC) activity accompanied with an increase in fixation durations, which suggests a shift in their attentional state, possibly from routine process execution to problem detection and resolution. The novices’ response was not as strong as that of experts, including a slight increase only in the left dlPFC with a decreasing trend in fixation durations, which is indicative of visual search behavior for possible cues to make sense of the unanticipated situation. A linear discriminant analysis model capitalizing on the covariance structure among hemodynamic and eye movement measures could distinguish experts from novices with 91% accuracy. Despite the small sample size, the performance of the linear discriminant analysis combining eye fixation and dorsolateral oxygenation measures before and after an unexpected event suggests that multimodal approaches may be fruitful for distinguishing novice and expert performance in similar neuroergonomic applications in the field.

However, the rise of these technologies also brings important questions about data protection and user autonomy. (shrink)

PREFACE WORD -/- Hilmi Ziya Ülken was born in Istanbul during the last period of the Ottoman Empire, was educated during this period and worked in many areas of the intellectual life of the newly established Republic. Although he was interested in many fields of social sciences, he gained fame in philosophy, sociology, history of thought and literature. Again, he undertook important tasks in revealing and introducing medieval Islamic thinkers and post-Tanzimat Turkish thought, and due to his deep knowledge (...) of Eastern and Western philosophies, he made comparative studies in these fields and tried to reveal the similarities and differences in both cultures. Many graduate studies, book chapters and articles have been written about such an important thinker whose works are also recognized abroad. Among the thinkers of the Republican Era, Ülken is one of the most studied names. In this study, Ülken's biography, his intellectual adventure, his understanding of philosophy and his ideas about the life of thought are discussed panoramically, and the bibliographic information obtained about his articles and other works that have not yet been fully revealed has been added to the study. Another important document added to this study is Ülken's biography written in his own handwriting. Our hope is that with the completion of the information missing in this study, a complete portrait of Ülken will be revealed. When Ülken's works are taken into consideration, it is understood that he wrote works in many fields of social sciences. The fact that he did not concentrate on a certain field but worked in many fields has been a frequently criticized aspect of him. In this sense, we think that the phrase "A Thinker of Mütebahhir", which we wrote as a subtitle to the title of our study, defines him very well. Many names have used the adjective mütebahhir, which means ocean and depth in Ottoman Turkish, about Ülken. While Necati Öner used it in a positive sense, names such as Cemil Meriç (1916-1987) and İsmail Tunalı (1923-2015) used it in a sense that includes negative connotations, such as saying words in every field, his knowledge is unlimited but formless and non-systematic, and Salâh Birsel (1919-1999) wrote on every subject. On the other hand, scholars such as Kurtuluş Kayalı and Ali Utku, who have recently conducted competent studies on Ülken, have emphasized that Ülken - contrary to popular belief - thought and worked within a system and was very sensitive about his system of thought. When Ülken's works are examined in general, it is seen that many of them were formed by turning lecture notes into books, and this situation caused many problems. This situation led to problems such as the disorganization of his works, the lack of a certain systematization, the lack of the necessary methodological sensitivity in footnotes and citations, and the use of some terms in their original language instead of their Turkish equivalents. When we look at the life stories of important thinkers in the history of thought, we observe that they were not only influenced by the social, political, economic, etc. conditions of the period in which they lived, but also that they influenced these conditions in the period in which they lived. The best example of this situation among the thinkers of the early years of the Republic is Ülken. When his works are examined in chronological order, it is noticeable that his ideas constantly changed, that he had to defend the ideas he criticized from time to time, and that he was in a constant search. He explained his works in many fields by saying that he wrote works that would be a source for his own works and that he served as a bridge to the past. The fact that he was a doyen in many fields of social sciences despite having a Mülkiye education can be explained by his self-education. Ülken, who set an example for academics and thinkers with his hard work, diligence, and lifestyle of constantly reading, researching and writing, carried out very important works in his 73 years of life. As Öner, a student of his who knew him closely, says: "In his daily life, Ülken was either reading, writing or philosophizing." Again, Tunalı says about his diligence that "when he was finishing a book, he would have written another book!" It can be said that one of Ülken's efforts was to establish a tradition of sociology and philosophy in Turkey by recognizing the disconnect in our world of thought. Ülken expressed this to his student Necati Öner by saying, "We are a quarter in philosophy, you will be half, and then we will be complete!" While the influence of philosophers and sociologists who came to our country with the educational reforms was quite limited, Ülken succeeded in establishing a tradition in Istanbul Sociology and Ankara Theology. For this reason, important sociologists and philosophers of our country, such as Baykan Sezer (1938-2002) and Kurtuluş Kayalı (born 1949), admitted that "we are students of the Ülken tradition" even though they were not his direct students. Ülken provided an important opening in the social sciences with his methodology that analyzed the problems he dealt with in depth, tried to deal with all aspects of the issues and made synthesis attempts between different ideas. In addition, with the newly established Republic, he made great efforts to collect and translate sources in many fields, especially philosophy, and to carry out activities on a philosophical basis. The fact that his works continued to attract attention in every period after him and were reprinted and read again and again reveals the centrality of his role in the intellectual life of the Republican period. In this study, in which the life, philosophy and thoughts of Hilmi Ziya Ülken, whose valuable contributions to Turkish-Islamic thought are undeniable, have been tried to be presented in general terms, the articles and book chapters I have written about Ülken in various journals and book chapters and whose titles I have given in the bibliography and bibliography section have also been utilized. I hope that this monographic study will make a small contribution to the studies on Ülken, who deserves to be remembered with mercy and gratitude. -/- . (shrink)

Prof. Dr. Mehmet Karasan 1907 yılında Denizli, Çivril’de doğdu . İlk ve orta öğrenimini Çivril ve Konya’da, lise eğitimini 1928 yılında İstanbul Erkek Lisesi’nde tamamladıktan sonra aynı yıl Millî Eğitim Bakanlığı’nın yurt dışı eğitim bursunu kazanarak Fransa, Lyon Üniversitesi, Edebiyat Fakültesi, Felsefe ve Sosyoloji bölümünde lisans eğitimi almaya hak kazandı. 1932 yılında yurt dışı eğitimini tamamlamasının ardından 1933 yılında İstanbul Üniversitesi Felsefe Bölümüne doçent olarak atandı. 1942 Yılında İstanbul Üniversitesi Felsefe Bölümü asistanı Nusret Hızır ve pedagoji doçenti Bedii Ziya (...) Egemen ile birlikte Ankara Üniversitesi Dil ve Tarih-Coğrafya Fakültesi Felsefe Enstitüsü kadrosuna katıldı. 1932-1950 yılları arasında belirli dönemlerde çeşitli okullarda felsefe, sosyoloji ve Fransızca öğretmenlikleri ve idarecilik yapan Karasan 1951 yılında Ankara Üniversitesi İlahiyat Fakültesi’nde Profesör olarak göreve başladı. Prof. Dr. Mehmet Karasan akademik hayatının yanı sıra 1954-1957 ve 1957-1960 yılları arasında X. ve XI. dönem Türkiye Büyük Millet Meclisi’nde Denizli Milletvekilliği yaptı. Siyasi hayatının ardından 1968 yılında Ankara Üniversitesi İlahiyat Fakültesi felsefe kürsüsünde Profesör olarak akademik yaşamına devam etti ve 1970-1971 yılları arasında aynı fakültede dekanlık görevinde bulundu. 15 Kasım 1974 tarihinde hayatını kaybeden Karasan Evli ve bir çocuk babasıydı. Mehmet Karasan Türk düşüncesine ve literatürüne Eflatun’un Devlet Görüşü (1947) ve Büyük Feylesoflar Antolojisi (1949) adlı kitapları, “İlk Yunan Düşüncesinde Din İlmi Denemeleri” ve “Eflatun’un Devleti” gibi makaleleri ile katkıda bulundu. Karasan, Fransa’da almış olduğu yurt dışı eğitiminin etkisi ve Cumhuriyet döneminde 1940 yılında Hasan Ali Yücel tarafından başlatılan “Tercüme Hareketi” vesilesiyle yabancı dilde yazılan birçok klasik eseri tercüme ederek dilimize kazandırdı. Platon, Descartes, Durkheim ve Bergson gibi önemli filozofların eserlerini tercüme ederek felsefe alanına önemli katkılarda bulunan Karasan, Durkheim’ın Meslek Ahlakı kitabını tercüme etmesi ve “Din Sosyolojisi, Öncüleri ve Kurucuları” başlıklı bir makale kaleme alması ile yalnızca felsefe alanına değil sosyoloji alanına da önemli katkılarda bulundu. Bu sayede Cumhuriyet döneminde akademik anlamda Türkiye’de ilk din sosyolojisi dersini 1949 yılında Ankara Üniversitesi İlahiyat Fakültesinde verdi. Karasan sosyolojiye yönelik çalışmaları ile birlikte özellikle felsefe alanında Descartes’ın İlk Felsefe Üzerine Metafizik Düşünceler (1942), Felsefenin İlkeleri (1943), Aklını İyi Kullanmak ve Bilimlerde Doğruyu Bulmak İçin Metot Üzerine Konuşma (1944), Tabiat Işığı ile Hakikati Arama (1945), Aklın İdaresi İçin Kurallar (1945) ve Ahlak Üzerine Mektuplar (1946) gibi birçok eserini Fransızcadan dilimize tercüme etmesi ve yapmış olduğu bu tercümelere eklemiş olduğu ön sözler ve açıklamalar ile Türkçe felsefe alan yazınında tanınırlık kazandı. Descartes’ın eserleri ile birlikte Fransızca’dan dilimize kazandırdığı eserler arasında Bergson’un Ahlak ile Dinin İki Kaynağı (1949), Lucien Laberthonnière’in Descartes Üzerine Tetkikler (1959) eseri ve bir dönem Ankara Üniversitesi Dil ve Tarih-Coğrafya Fakültesi Felsefe kürsüsünde görev yapan Olivier Lacombe’un bazı makaleleri de bulunmaktadır. Böylece, Mehmet Karasan Descartes’ın felsefesi başta olmak üzere Fransız düşüncesi ve felsefesinin Türkiye’de tanınması açısından önemli bir görevi yerine getirdi. Prof. Dr. Mehmet Karasan Türkiye Cumhuriyeti’nin görece ilk yılları sayılabilecek dönemi içerisinde sorumluluk alarak felsefe ve edebiyat alanında hem tercüme faaliyetleri hem de kendi özgün eserleri ile Türk düşüncesinin ve felsefesinin gelişimine yardımcı olan bir düşünürdür. Karasan’ın başta Fransız felsefesi olmak üzere felsefeye yönelik düşüncelerinin günümüz entelektüel çevresi ve araştırmacıları tarafından tanınması önem teşkil etmektedir. Ancak Mehmet Karasan’ın düşünce hayatı, felsefi görüşleri ve felsefeden ne anladığına yönelik yapılan çalışmaların azlığı ve eserlerine ulaşmanın zorluğu göz önünde bulundurulduğunda onun yaşamı ve felsefesine yönelik mevcut bilginin eksikliği göze çarpmaktadır. Bu nedenle Mehmet Karasan’a yönelik bir çalışma ortaya koyma gerekliliği ortaya çıkmaktadır. Bu gereklilik doğrultusunda yazımızda Karasan’ın ortaya koymuş olduğu çalışmalarının seyri ve gelişimi takip edilerek görüşleri aktarılmaktadır. Bu noktada onun tercüme eserlerine yazmış olduğu ön sözler ve açıklamalar dikkate alınmaktadır. Böylece, Karasan’ın özellikle Descartes’tan yaptığı tercümelerden hareketle onun felsefi yaklaşımına ve felsefeden ne anladığına ilişkin bir tahlilde bulunulmaya çalışılmaktadır. Belirtmek gerekir ki bu yazının temel amacı Descartes’ın felsefesini ya da felsefi görüşlerini aktarmak değil Mehmet Karasan’ın Descartes’ın felsefesine yönelik okumaları, çıkarımları, düşünceleri ve katkılarını tespit ederek kendi özgün düşüncelerini ve felsefi tavrını ortaya koymaktır.
