    In this study, the sexual incompatibility of Paviot and Levent apricot parents and 89 F1 (Paviot × Levent) progenies was determined by self-pollination experiments and S-allele-specific polymerase chain reaction (PCR) technique. According to the self-pollination and isolation analyses under field conditions, it was found that the Paviot genotype is self-compatible (SC), whereas the Levent genotype is self-incompatible (SI). It was determined that, of all the progenies, 55 had a fruit set below 5% and were self-incompatible, whereas 34 had a fruit set over 5% and were self-compatible. The PCR-based techniques showed that, in parallel to the data obtained from the field studies, 55 F1 progenies did not have Sc allele, whereas 34 progenies involved Sc allele. There were ScS2 alleles in the Paviot genotype and S20S52 alleles in the Levent genotype. It was determined that there were S2S20, S2S52, ScS20, and ScS52 alleles in 89 F1 progenies and the distribution of the four alleles in the progenies was found to be as follows: 35.9% S2S20, 25.8% S2S52, 23.6% ScS20, and 14.6% ScS52. F1 progenies nos. 41, 46, 86, and 89 should be used as pollinators in further breeding studies

    Mimarlık tartışmalarının önemli bir bölümünü oluşturan `barınma' konusu, gündelik yaşam ile doğrudan ilişkili olması dolayısıyla oldukça önemlidir. İlk çağlardan beri barınma problemleri ile karşı karşıya kalmış insanoğlu, çevresi ile kurduğu ilişkileri, yaşadığı konut alanları üzerinden de anlamlandırmaya çalışmıştır. Bu çerçevede, günümüzün konut alanları da insan hayatında türlü değişimlere sebep olmaktadır. Özellikle 2000 sonrası ortaya çıkan konutlar, insanlara yalnızca farklı bir mimari sunmakla kalmamış, yeni bir yaşam biçiminin de ortaya çıkmasına sebep olmuştur.Bu çalışmada, Levent bölgesinde konut olarak inşa edilmiş binalar planlama kararları ve bölgesel gerçekler temel alınarak yatırım, tasarım, teknik, ticari, lokasyon-ulaşım-sosyal çevre konularının oluşturduğu tespit ve analizler çerçevesinde incelenmiştir. Ayrıca günümüzde geçerliliğini popüler konut alanı olarak sürdüren Levent bölgesinden rastlantısal olarak seçilen örnek konutların analizi yapılmıştırBirinci bölüm; çalışmanın hedeflerinin ortaya konması ve kapsam üzerinedir.İkinci bölüm; İstanbul'daki konut binaları tarihçesi, gelişimi ve günümüzde kullanılan örnekleriyle incelenmiş, kullanıcı tercihleri doğrultusunda modern konut tanımı yapılarak Loft kavramının ortaya çıkış konusuna değinilmiş ve son olarak da Loft binalarının yaşam kalitesi üzerindeki etkileri ele alınmıştır.Üçüncü bölüm; zaman ilerledikçe İstanbul kentsel alanında değişimler yasanmış, kent her yönde büyümeye devam etmiştir. Kentin yayılımı sürecindealınan planlama kararları, yapılan boğaz köprüleri, çevre yolları, merkezi is alanının kuzey yönünde ilerlemesi ve gökdelenlerin Levent Bölgesi'nde yoğunlaşması, mahallenin yapısında değişimler incelenmiştir.Dördüncü bölümde; Levent bölgesinde üzerinde alan çalışması için seçilmiş olan Büyükdere aksının tespit ve analiz çalışmaları yapılmış; belirlenen konut tipleri alanda tespit edilerek, günümüzdeki değişimleri, tablolar ve Şekiler esliğinde açıklanmıştır.The issue of `accommodation?, forming a significant part of architectural discussions, is highly important as it is directly related with day-to-day life. Facing accommodation problems since the first ages, humanbeings have tried to give meaning to their relations with their environs through their housing areas, among other things. Within this framework, today?s housing areas, too, bring about a variety of changes in human life. Especially housing units built since 2000 not only provided people with a different architecture but also brought about a new lifestyle.This study discusses the buildings constructed as housing units in district of Levent with reference to planning decisions and regional realities within the framework of findings and analyses based on aspects of investment, design, technics, business, location-transportation-social environment. Moreover, some housing units sampled ramdomly in district of Levent which still remains a popular housing area have been analyzed.Part one clarifies purposes and and scope of the study.Part two discusses history and development of housing buildings in Istanbul, giving examples of the surviving ones, and deals with the issue of emergence of Loft concept giving a modern housing definition in line with user preferences and, finally, describes effects of Loft buildings on life quality.Part three deals with the fact that Istanbul urban area has, as time went by, gone through changes and the city has continued to grow towards all directions. So, this part discusses planning decisions made during the process of city?s expansion, bosphorus bridges built, ring roads, expansion of central business area to the north and concentration of skycrappers in District of Levent, as well as changes all this have brought about in the district?s structure.Part four outlines findings and analyses conducted on the Buyukdere axis selected as place of field research in district of Levent; identifying types of housing units determined on the field, as well as current changes, as accompanied by tables and figures

    Tez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 1995Thesis (M.Sc.) -- İstanbul Technical University, Institute of Science and Technology, 1995Levent'teki konut kullanımının işyerine dönüşümünü, Levent'in tasarım kararlarını ve gelişimini, meydana gelen fonksiyonel gelişimin fiziksel ve sosyal yapıya etkisi ile sonuçlarını ortaya koymayı amaçlayan çalışma, dört bölümden oluşmaktadır. İlk bölümde, konunun seçim nedeni, amacı ve çalışma yöntemi açıklanmıştır. İkinci bölümde, tasarımda etkili olan kriterler, duyarlı çevre yaratmada etkili olan kriterler ve duyarlı çevrelerin kullanıcı üzerindeki etkisi incelenmiştir. Üçüncü bölümde, Levent'in kurulduğu günden bugüne kadar geçirdiği gelişim ve değişim incelenmiştir. Levent'teki konut ve konut-dışı fonksiyonlar ile, binaların değişim durumu ve kat yükseklikleri tespit edilmiş, fiziksel değişimin yanısıra görsel analiz çalışmalarıyla görsel değişim de saptanmaya çalışılmıştır. Alanda yaşayanlarla anketler yapılarak, Levent'teki sosyal yapı, ulaşım durumu, fiziksel açıdan bina memnunuyeti ve fiziksel değişim, ihtiyaç duyulan donatı ve fonksiyonlar, fiziksel ve görsel açıdan semt memnuniyeti doğrultusunda kullanıcıların duysal olarak etkilenme durumları ve halk katılımı için düşünceleri tespit edilmeye çalışılmıştır. Levent'in fonksiyonel ve fiziksel ne gibi değişikliklere uğradığı belirtilmiş, bu değişimlerin kullanıcı üzerinde bıraktığı duysal etkiler irdelenmiş, duyarlı bir çevrenin önemine dikkat çekilmiştir. Çalışmanın dördüncü bölümü olan sonuç ve öneriler bölümünde ise, İstanbul'da gelişen yeni merkezlerden Levent'in de etkilenip fonksiyonel, fiziksel ve sosyal değişime uğraması sonucu duysal çevre yaratmada etkili olan uyum, devamlılık, kavranabilirlik gibi kriterlerin gittikçe kaybolduğu ve bunun kullanıcı üzerinde olumsuz etki bıraktığı saptanmıştır. Bu nedenle, üst düzey planlar yapılıp, Levent'in gelişiminin plan kararlan doğrultusunda gerçekleşmesi önerilmiştir. Buna ek olarak, kullanıcıları fiziksel ve duysal olarak etkileyen çevrelerin yaratılmasına önem verilmesi öngörülmüştür.The aim of this study is to determine the functional, physical, social changes in Levent and their effects on the users. In the first chapter, the reason of choosing the subject, the purpose and the study methods are explained. In the second chapter, a literature survey is made in order to gain the criteria needed in design to create responsive environments. The importance of these environments are tried to be explained. In the third chapter, development and change of Levent are researched, beginning with the first step until today. Certain fixings are made to analyze the reasons and effects of business use, changes made in the area and in the buildings. Then, the functional, physical and visual changes are found out. The effects of these changes on the area and on its users are tried to be set. In the last chapter, which is the result and the suggestions part, it is suggested to produce plans in order to realize the changes in Levent as wanted and necessary. It is also suggested to create good, natural environments that will affect the image of Levent and therefore, its users. Until 1947, Levent was an open area with mulberry trees, outside of Istanbul. In 1947, Real Estate Bank bought the area and planned to offer it for residential use. Plans are drawn by architect (prof) Kemal Ahmet Aru and architect Rebii Gorbon. The aim was to build one or two storey houses with gardens that will be used as social housing that are different than the apartment buildings. The most important physical qualities of Levent are its houses with gardens and its green areas. Levent improved through a plan but the changes happened independent from the plans. What was planned as a social housing area in 1950's, turned out to be a luxurious area in 1990's. It was planned to serve to housing purposes, but now, these houses are used for business reasons as well. Several types of houses with different heights are planned in Levent. The reason for this was to prevent the area from monotonous movement. The main purpose in designing Levent was to create an area which is beautiful, comfortable, not monotonous and will not cost much to design. Initially, First Levent was planned. The construction started in 1948 and completed in 1952. People were veiy much interested in the houses, so, immediately Second and Third Levent are started to built. Here, the target group was the middle-class, again, although some of the houses were built bigger than the ones in First Levent. Before starting the construction, with the experience gained from First Levent, more importance was given to the adaptation to the land in order to prevent problems and to answer some needs. Certain targets are determined and tried to be realized. 1. Roads will not be connected to each other if not necessary, 2. Vehicle and pedestrian roads are separated from each other, partially, 3. The number of the houses built on both sides of the main road are decreased in order to prevent the monotony, 6. Main traffic road is designed to be 12 meter, others are designed to be 9.5 and 7.5 meters. With the direction of the targets, listed above, the construction began and was completed in 1953. It was planned that First, Second and Third Levent have their own centers within themselves but this was realized only for First Levent. XVI It was planned that First, Second and Third Levent have their own centers within themselves but this was realized only for First Levent. Real Estate Bank bought an area of 20 hectares when the First, Second and Third Levent were in high demand. Between 1954 and 1958, Fourth Levent was constructed. With the direction of several changes in the world and in Turkey, mix compositions are realized according to the family types. Apartment buildings with different heights are planned. According to the size of house some of them were no longer considered as social-house. One specialty of the houses in Fourth Levent was that the property was the base area, the borders of the properties were passed 1 meter outside the building and rests of the gardens are left to the municipality. This is an important reason in keeping its green areas, even now. Three centers are offered in Fourth Levent. In these centers; night-clubs, play grounds, garage, cinema, sports area, kinder-garden and similar functions are offered. While Fourth Levent was being planned, another important subject is the importance given to art as well as to architecture. Famous artists of that time are invited to the area and they were asked to do some paintings on the buildings. When the designs of First, Second, Third and Fourth Levent are compared, it can be seen that different house groups are planned in Fourth Levent for different family groups and special importance is given to art. In Fourth Levent, the centers are designed in detail. In First Levent a center is designed as well but in Second and Third Levent no center was realized. During the development of Istanbul, Levent was affected because of several changes. In İstanbul, the city center started to move along the Şişli- Mecidiyeköy-Zincirlikuyu-Maslak axle. In addition to this, with the increase of the population construction of new areas to be formed towards outside from the center. XVH Until 1991, Levent was shown as a housing area on Beşiktaş District, The Bosphorus Foreseen and Attraction Zone Plan, scale 1/5000. After the road connections and with the movement of the business centers towards this zone, it was considered that Levent would be affected by this change. As a result, in 1991 Beşiktaş District, The Bosphorus Foreseen and Attraction Zone Plan, commercial use for tourism function along Nispetiye Caddesi is decided. Existing size and heights of the buildings would be protected. After this decision, the area began to serve for banks, offices, restaurants, bars, night clubs, etc. Right after this decision, Levent began to go through a process of change. In 1993 Beşiktaş District Foreseen and Attraction Zone Plan, another decision was given permitting the area for social and cultural establishments and buildings for administration purposes. In addition to this, Levent was accepted as a prestige area. Today, the improvement and functional change in Levent are still continuing. Levent, winch was designed for housing purposes is serving to business purposes today, as stated above. A survey was made by Nuran Zeren Gülersoy, Serap Demir and Ayşe Paşalıoğlu in 1994 to examine the functional changes in Levent, involving 88 business. According to this survey, there are several reasons of choosing the area for business purposes. These purposes are listed below: Prestige area: 35 %, Quite, peaceful and green: 25 % Availability commercial use: 5 % Owned property: 1 5 % Easy transport facilities: 10 % Closeness to the consumers: 5 % No parking problem: 5 % Functional change affected Levent physically. The types, heights, color of houses changed. The streets began to be filled with cars. People started to build garden walls around their houses. Because of these reasons, the visual image of XVlll the city changed. People began to perceive it in a different way than they used to. Levent started to lose its identity and its characteristics. A questionnaire is made in Levent involving 50 families living in the area. Their ideas about social organization, transportation, pleasure from the buildings in physical aspect and physical change, functions and establishments needed, sensuous effects on the users and community participation are gained through the questions. As a result, it is found out that the people living in Levent are very-well educated and most of them have the top positions in their business. Generally they can reach their houses easily, since the traffic is better when compared to the other parts of the city. According to its inhabitants, Levent is a peaceful, clean, green, high-quality area with 1 or 2 storey houses. The restaurants, bars and night-clubs that make noise all-night long are found to be the most negative aspect of Levent. The inhabitants do not like the high-rise buildings built after 1990 around Levent, because they affected Levent physically creating traffic gem. People living in Levent believe in community participation to raise the quality of the environment. Therefore they want to be involved in such events. After the problems of the existing situation is understood and defined and it is suggested that upper-level plans should be prepared and improvements must be realized according to these plans. Type of business and trade activities and the norms of the buildings for commercial use must be fixed. It is required and important that qualitatively and quantitatively enough green areas must be created to satisfy the recreational needs of the people living in Levent. The area must have an identity having its own special characteristics and as the result of this, a distinguished area can be obtained with happy and satisfied users.Yüksek LisansM.Sc

    Diffusive author(s), cohesive author: Analysis of S/N (1994)

    No full text
    This study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)

In this phenomenological study, the data were collected by using a semi-structured interview form with 14 academic staff members teaching in public universities in Istanbul, Ankara, Edirne, Izmir, and Manisa. The obtained qualitative data were analyzed by using MAXQDA and coded under certain themes. The findings show that verbal and psychological (emotional) bullying is the most common type of bullying bullying in the classroom observed by the academic staff members. While most of the participants stated that they indirectly intervened in the cases of peer bullying they witnessed, having older students and feeling pedagogically not competent enough to intervene in bullying were the biggest challenges impeding action. When asked about their suggestions on the subject, the participants stated that in-service trainings about peer bullying at the institutional level should be organized and that faculty administrations should play an active role in organizing these trainings and creating institutional policies about peer bullying

    Going Beyond Counting First Authors in Author Co-citation Analysis

    No full text
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
