ÇOK ULUSLU ŞİRKETLER, STRATEJİLERİ VE KÜRESELLEŞMEDEKİ ROLLERİ
Full text linkOn the one hand, it is claimed that a new world order from which unprecedented successful performance will be obtained thanks to the globalization system is established or all countries in the world will obtain useful results from the globalization process in the world. On the other hand, it is mentioned about critics regarding arrangements intended for only huge companies called as multinational within globalization system and commercial opportunities of very developed countries which these companies belong to are made. As long as effects started to be experienced as a result, it is clearly understood that the real goal is to provide integration and consolidation all over the world because it is seen that very important developments will be obtained by developing countries which are the ones most benefiting from this process in some ways after quarter century. In this study, effects of globalization on positive results provided by multinational companies in this globalization system and different results arising from country managements are obtained on which ones among these effects are searched.
Jel Codes: F6Dünyada küreselleşme sürecinde bir taraftan küreselleşme sistemi sayesinde günümüze kadar görülmemiş kadar başarılı bir performans elde edilecek olan yeni bir dünya düzeni kurulmaya çalışıldığı veya dünyadaki bütün ülkelerin aynı yararlı sonuçlara ulaşacağı iddia edilmektedir. Diğer taraftan küreselleşme sistemi içinde sadece çok uluslu denilen devasa büyüklükteki şirketler ile bu şirketlerin ait oldukları çok gelişmiş ülkelerin ticari olanaklarına yönelik düzenlemelerle ilgili eleştirilerden bahsedilmektedir. Sonuç olarak yaşanmaya başlanan etkiler ortaya çıktıkça gerçek amacın bütün dünyada birleşme ve bütünleşme sağlanmış olduğu açıkça anlaşılmaktadır çünkü ancak çeyrek asır sonra aslında bu sürecin fazla yarar sağlayanları olarak gelişmekte olan ülkeler tarafından bazı açılardan çok önemli yararlar elde edileceği görülmektedir. Bu çalışma kapsamında küreselleşme sisteminde aslında çok uluslu şirketler tarafından sağlanan olumlu sonuçlar üzerinde küreselleşmenin etkileri ile bu etkiler arasında hangileri üzerinde ülke yönetimlerinden doğan sonuçlar elde edildiği araştırılmaktadır.

ÇİN’İN KÜRESELLEŞME İÇİNDE ROLÜ: YENİ BİR HEGEMON MU?
Full text linkChina is taking on the role of a global actor that has been strengthened with the outward policy practices that started in the 1970s. The main question of this article is whether it has the intention and power to take over the current hegemony in globalization as a result of the striking developments in production, trade, innovation, energy use and transnational capital and the advantages of being the fastest growing country on average. Therefore, the question of China's labor costs and advantages and growth with the Lewis Turning Point (LTP) and the Middle Income Trap has been dealt with, in particular, taking into account the post-crisis conditions. The effects of the global crisis and the US-China trade wars on the Chinese economy were questioned, among other things, to increase the total factor productivity in overcoming the Middle Income Trap.

Bu süreçte üretim, ticaret, inovasyon, enerji kullanımı ve ulusötesi sermaye konularında yaşadığı çarpıcı gelişmeler ve ortalama en hızlı büyüyen ülke olmanın getirdiği avantajlar neticesinde Çin’in küreselleşmede mevcut hegemonyayı ele geçirmek gibi bir niyetinin ve gücünün olup olmadığı konusu, bu makalenin ana sorusunu oluşturmaktadır. Bu nedenle makalede Çin’in işçi maliyetleri ile ortaya çıkan avantajlarının ve ülkedeki büyümenin, Lewis Dönüm Noktası (LTP) ve Orta Gelir Tuzağı kavramsal çerçevesiyle sorgulanması, özellikle küresel kriz sonrası oluşan koşullar gözönünde bulundurularak yapılmaktadır. Çalışmada, Çin’de Orta Gelir Tuzağının aşılması yolunda toplam faktör verimliliğinin arttırılması ve diğer önlemlerin yanısıra küresel kriz ve ABD-Çin Ticaret Savaşlarının Çin ekonomisine etkileri sorgulanmıştır.

HEGEMONYA VE SINIFSIZLIK BİLİNCİ
Full text linkContinuity of the hegemony is largely achieved by the socialization process and construction of the social consciousness in the process.While hegemony provides a window to see the world through the eyes of the ruling class, it also prevents ideas that are harmful to it from spreading, studied and accepted. So it is unrealistic to expect a social consciousness that was constructed in favor of the ruling class to include class consciousness.
Foundation of the class consciousness is the feeling of belonging to a class. However the class consciousness is a threatening element to hegemony. So this study was done believing that social consciousness acts for the continuity of the hegemony, based on ''an ordinary person doesn't have a clear 'social class concept' in their mind, which brings belonging feelings and class consciousness, the notion is vague in their minds.'' hypothesis.
In a research that was conducted between March-July 2019 by stratified random sampling method, the participants were asked in an open ended way ''Which class do you feel belonging to?''. Instead of a question aiming to make the participants choose between multiple answers of already existing class templates, the open ended question aimed to discover what the participants know about class structures that are used in defining them and how they interpret these classes in their minds.
During the study it has been observed that one third of the participants didn't have a meaningful interpretation of the class concept corresponding in their minds thus being unable to answer the question. Nearly half of the participants who answered the question stated they think themselves as ''middle class''. Among the participants who stated they belonged in the ''middle class'', it is remarked that a quarter of them never once bought a book, 31 percent never visited the theatre, 6.7 percent never traveled out of their city and 5 percent never dined in a restaurant in their lives.
When evaluating the income level of the participants who thought they belonged in the ''middle class'', it was discovered that 45.3 percent of the participants were of minimum wage to lower or no income for themselves while 51 percent of the participants had an income of minimum wage to 6k liras which showed that over half of the participants who thought themselves belonging in ''middle class'' were on the border of the poverty threshold.
When factors like education, income level, social and cultural way of life considered, it was understood that the participants who gave the response ''middle class'' were implying the middle class of their vicinity, not the middle class defined by ranking of 20 percent income groups.Hegemonyanın sürekliliği büyük ölçüde toplumsallaşma süreci ve bu süreçte inşa edilen toplumsal bilinçle sağlanır. Hegemonya, dünyaya egemen sınıf açısından bakmayı sağlayacak bir çerçeve sunarken, kendisi için tehdit oluşturan fikirlerin yayılması, öğrenilip benimsenmesini önlemeyi de içerir. Dolayısıyla egemen sınıf lehine inşa edilen toplumsal bilincin sınıf bilincini içermesini beklemek gerçekçi olmaktan uzaktır.
Sınıf bilincinin temeli, bir toplumsal sınıfa aidiyet hissedilmesidir. Ancak sınıf bilinci hegemonya için tehdit oluşturan bir unsurdur. Bu araştırma da toplumsal bilincin hegemonyanın sürekliliği için işlev gördüğünden hareketle “sıradan insanın zihninde aidiyet hissi ve sınıf bilincine sahip olabileceği net bir “toplumsal sınıf” kavramının olmadığı, konunun zihninde muğlak olduğu” varsayımından yola çıkılarak gerçekleştirilmiştir.
Mart-Temmuz 2019 arasında tabakalı rastgele örneklem yöntemiyle gerçekleştirilen araştırmada katılımcılara “Kendinizi hangi sınıfa ait hissediyorsunuz?” sorusu açık uçlu olarak yöneltilmiştir. Mevcut toplumsal sınıf kategorileri içinden birini seçmeye yönelik çoktan seçmeli bir soru yerine açık uçlu soru ile katılımcıların zihninde sınıf kavramının neye karşılık geldiğine ve kendilerini tanımlamak için kullanılan sınıflamalardan ne kadar haberdar olduklarına dair bilgi edinmek amaçlanmıştır.
Araştırmada, katılımcıların yaklaşık üçte birinin zihninde sınıf kavramının anlamlı bir karşılığı olmadığı ve soruyu yanıtlayamadıkları gözlenmiştir. Soruyu yanıtlayanların yarıya yakını kendilerini “orta sınıf”a ait hissettiklerini belirtmişlerdir. Kendini orta sınıfa ait hissettiğini söyleyen katılımcıların dörtte biri hayatları boyunca hiç kitap satın almadıklarını, yüzde 31’i hiç tiyatroya, yüzde 6.7’si hiç yaşadığı yerden başka bir şehre gitmediğini, yüzde 5’i hiç lokantada yemek yemediğini belirtmektedir.
Kendini orta sınıfa ait hissettiğini söyleyen katılımcıların gelir düzeyleri değerlendirildiğinde yüzde 45.3’ünün asgari ücret ve altında ya da kendine ait bir geliri olmayanlardan oluştuğu, yüzde 51’inin asgari ücretle 6 bin TL arasında aylık gelire sahip oldukları yani yarısından fazlasının gelirlerinin açlık ve yoksulluk sınırlarında olduğu görülmektedir.
Eğitim, gelir durumları, sosyal ve kültürel yaşamlarına dair veriler de göz önüne alındığında bu yanıtı verenlerin (yüzde 20’lik gelir grupları sıralamasıyla oluşturulan toplumsal sınıflamaya göre orta sınıfı değil) kendi yaşadıkları çevre içindeki orta sınıfı kast ettikleri anlaşılmaktadır
GROWING POSSIBILITIES OF MEDICINAL AND AROMATIC PLANTS IN GREENHOUSES CLIMATIZED BY BIOGAS POTENTIAL IN TEKIRDAĞ REGION
Full text linkMedicinal and aromatic plants that are generally grown in natural environment and obtained by collection from these natural environments cannot meet the need.In this respect, it is possible to increase the possibility of growing medicinal and aromatic plants by providing the necessary climatic conditions especially with greenhouse systems. In the greenhouse, the highest cost is the provision of air conditioning. In this respect, greenhouse air conditioning system can be provided with renewable energy or waste materials. In this study, information on some medicinal and aromatic plants that can be grown in greenhouses conditioned by biogas which can be produced from wastes of bovine and ovine animal production structures in Tekirdağ region where agriculture and animal husbandry are carried out intensively in our country and waste evaluation can be obtained without being subject to low cost medical and aromatic plants. intended.

ISTANBUL HOUSING AND LAND APPRAISAL SYSTEM REFORM DEVELOPMENT PROCESS AND PROPERTY VALUES ANALYSIS
Full text linkOne of the main problems of developing countries is having difficulties in finding sources for housing finance. In order to solve housing finance problems of a country, institutional systems that have been structured according to its own economic and social conditions should be applied by the government. The main purpose of this study is to determine an appropriate housing finance development designed based on Turkey’s current conditions. In this study, the location of the construction sector in Turkey's economy, development of real estate sector in Turkey, the embryonic period of the housing market, development of criteria and indicators in the housing sector reform in the housing system were investigated. The construction sector is a so-called locomotive instruction of the economy. Turkey in the building industry as one of the economies in this category, especially after the 1980s and is growing constantly evolving. Today, the real estate sector has entered a rapid development process. Importance has been given to user needs in the projects produced and marketability has started to be seen as one of the most important factors of project success. For the solution of the housing problem, all the legal and operational measures taken by the state and the priorities determined are called housing policy. If the housing policy concept is to be examined, how the housing becomes a field of policy-making, how housing policies manifest in developed and underdeveloped countries or the problems encountered in its formation and performance can be studied and explored separately. Housing problems, housing policy and examine engagaments held in Turkey on a private housing finance field are reached some conclusions. The first one is the fact that the housing problem is a dynamic structure and may vary periodically in Turkey as it is in the world due to changes in demographic structure, stock depreciation and migration. Second, it is compulsory that the issue of housing as an economic asset increases with the globalization of the world, and that it is necessary to address this issue more carefully in countries that are in the process of transition to global economic integration. Third, the rapid population growth in Turkey (albeit with a relatively slow) will continue in the coming 20-year period together with urbanization, especially the aging of the stocks that make up the majority mania apartment blocks began in 1950-1960's year, worn with together will increase the destruction. A housing policy that is designed with these principles in mind; Financial Interventions to be carried out on housing investments, taxes, loans, housing purchase methods and similar areas, rent control and condominium applications, legal interventions to be carried out on various legal restrictions and incentives and housing standards, housing production types, construction methods and building materials technical interventions. At the end of this study, it is understood that housing finance model based on mortgage backed securities can be applied in the near future in Turkey. However, there are some requirements and regulatory needs must be fulfilled in many fields, such as in law of bankruptcy, tax regulations, law of banking and leasing, capital markets, and real- estate appraisal applications.

USE OF AGRICULTURAL WASTE ASHES AS ADDITIVES MATERIAL IN BIOACTIVE GLASS PRODUCTION
Full text linkDemand for renewable energy sources is increasing day by day. The rapidly increasing population and energy needs on a global scale have increased the number of studies on renewable energy sources. In addition to energy needs, the search for disposal and storage of wastes harmful to the natural environment is of great importance. Disposal and storage requires high costs and labor. The need for energy and the necessity of protecting the natural environment provided the solution to convert wastes into energy or value added products without damaging the environment. The wastes of the crops produced as a result of agricultural production can be converted into energy or value added products. Some of the plant wastes meet the energy needs and some of them can be used in the production of value-added biomaterials. Biomaterials are materials which are used in the field of health and show bioactivity with parts such as organs and tissues. Bioactive glasses, which are one of these materials, are used in the health sector especially in dental filling, prosthesis and composite applications. The most important feature of raw materials to be used in the production of bioactive glasses is SiO2 (silica). Plants receive silica from soil during development and this silica is also present in plant waste. In this study, a wide literature review was conducted and the percentage of mass ash after burning of rice stalks, corn stalks, hazelnut shells, corn stalks which were firstly burned for heating and energy purposes were determined. Then, the composition of the ash obtained SiO2 (silica) and other substances were determined and all the results obtained in the light of this information was compiled to provide information about the possibilities of use in bioactive glass production
