Impact of micro loans on agricultural production: A case study of wheat production in Bahawalpur, Pakistan
This study aims to investigate the role of Zarai Taraqiati Bank's limited finance through technology adaptation on wheat productivity in Bahawalpur, Pakistan. Lack of resources and technology are the main reasons why a lot of underdeveloped economies are not able to fulfill their potential especially in agriculture, which is generally the prime income source and occupation. This study is based on a primary data source collected through a field survey. The simple random sampling and cluster random sampling technique is employed for deriving representative sample from population to establish the relationship response variable and focus variables while controlling for land holding and farmer education. It is concluded that agriculture financing through high-yielding varieties, fertilizer, tractors, and harvesters have a significant impact on wheat productivity. The long-term loans also made a marked impact on wheat productivity, while the household size and education are negatively associated with wheat productivity, but these variables are insignificant. The positive association between long-term loans and agricultural productivity represents that credit enables the farmers to purchase superior quality inputs and equipment which causes an increase in agricultural yield. The study suggests that the in-time provision of the appropriate amount of loan and credit in kind (i.e., fertilizer, tractor etc.) to farmers may increase productivity. As a result, income and assets of the farmers are also enhanced.

Factors affecting bank selection in export financing: The case of Turkey
Exporters frequently rely on trade finance to facilitate international trade transactions, and the choice of a bank can profoundly impact the success of these transactions significantly. The current research aims to identify essential factors that exporters consider when selecting a bank in Turkey. We developed a conceptual framework to achieve this goal, drawing from consistent factors highlighted in various studies as critical criteria for bank selection. Employing a five-point Likert scale questionnaire as the primary research instrument, participants' agreement or disagreement levels were measured across 32 variables. Statistical analyses were conducted using Statistical Package for the Social Sciences (SPSS) and Microsoft Excel. The research sample for this study encompassed a total of 130 participants. Data analysis involved an exploratory factor analysis, aimed to insert interconnected variables into more comprehensive underlying factors. Principal Component Analysis, employing the varimax rotation method, was utilized to analyze the responses. Internal consistency was assessed through Cronbach's alpha test to ensure reliability across different factor groups. The analysis results indicate that the top three influential factors guiding bank selection among exporters are security and anti-fraud measures, twenty-four-seven customer support, and speed and efficiency of transactions. Utilizing the Principal Component Analysis extraction technique, the rotated component matrix effectively grouped the thirty-two variables into five major correlated factors: Diverse Product Offerings and Services, Informational Excellence and High-Quality Services, Bank Classification, Marketing Strategies and Customer Loyalty, and Bank Reputation. Overall, this study contributes valuable insights into the decision-making process of bank selection among exporters, shedding light on the factors influencing their choices within the Turkish context.
Freedoms of the air and effects of 5th freedom implementation at Ankara Airport
The purpose of this thesis is to analyze the Civil Aviation Regulations, and to prove that the more a market is liberalized, the better chance it has to grow. Many civil aviation authorities are strict regarding airlines of third-party countries in order to protect their own market and to support their flag carrier. However, it is possible to use third-party countries' airlines in order to grow the market and while supporting their own flag carrier. Unproductive airports and Flight Information Regions might be used to set the market in motion. This thesis contains six chapters. After Introduction and Literature Review the third chapter contains the definition of Air Freedoms. Chapter four contains the Study Methodology. In the fifth chapter, the Civil Aviation Authority Singapore, which has one of the most liberalized regulation policies, has been evaluated. The positive and negative effects of implementing the model of Singapore, at the Ankara Airport which has a capacity of 25M passenger per year has been determined. For data and statistics figures from IATA have been collected. The last part contains the conclusion. For this research, quantitative methods have been used, along with the descriptive method.
The impact of world gold prices on the stock market indices of emerging markets: A panel data analysis
The integration of international financial markets and linkages between financial and economic variables have instigated policymakers to try to influence and exercise control over the behavior of some of these variables through policies and investors to make informed investment decisions. Among such variables are stocks that are traded on stock markets. It performs a vital function in the economy and is easily tradeable. It is therefore prudent that its relationship with other economic and financial variables be known for making informed decisions. This research employed monthly data on gold, exchange, inflation, interest rates, and stock market indexes of 19 emerging economy countries for the period 01/2004-12/2019 to scrutinize the relationship between them with stock as a dependent variable. The dynamic panel ARDL model is employed for the research. The results showed the presence of a long-term relationship between stock indices, gold, exchange, inflation, and interest rates. In the long-term, inflation and interest rates are having highly significant coefficients. Both inflation and interest rates have a negative relationship with stock prices. Gold and exchange rate do not have any significant impact on stock indices in the long-term. However, in the short term, with the exception of inflation, all the variables are significant. Traditional theory holds in the long-term whilst in the short-term, portfolio theory holds. Gold does not serve as a hedge nor a diversifier in the long-term but serves as a diversifier for stocks in the short-term, inflation only has an impact on stock prices in the long-term and interest-bearing assets serve as an alternative investment hub to stocks both in the short and long-term.
The effect of economic and political relations on Turkish Airlines' route decisions
This thesis research aims to put a clear understanding on strategic decisions and activities of Turkish Airlines as a part of the public diplomacy, in other words, soft power. Since the 1980s, Turkish Airlines made an important contribution to Turkish foreign policy. The company has often been used as a tool of public diplomacy. This situation increased significantly after the declaration of the Africa Opening Policy. The objective of this study is to investigate the relationship between economic and political decisions made by Turkish authorities and the private sector and the strategic decisions of Turkish Airlines. For this purpose, an analysis of data considering 9 countries which are Colombia, Latvia, Sri Lanka, Tanzania, Cameroon, Mali, Madagascar, Chad and Ghana, is conducted to figure out whether there is such a relationship. The findings suggest that, there is a positive correlation between traffic numbers and foreign trade. However, a significant result can be obtained by adding revenue per flight, detailed passenger number and increase in the sample countries. Both values, traffic numbers and export level increased significantly after the opening of the embassy in the chosen countries, these actions were supported by other means of soft power such as TIKA and DEIK.

The effects of global oil prices on local stock market indexes of emerging markets: A cross-country analysis
The study investigated the effect of global oil prices on local stock market indexes of emerging markets for both oil exporting and oil importing countries. Data covering the period from January 2010 to March 2021 for 15 emerging countries was used. Two objectives guided the study. First, the impact of global oil prices on local stock markets was assessed. Secondly, the relationship between stock price and changes in macroeconomic variables was investigated. A panel regression model was carried out to analyze the data. The findings show that global oil price is negatively related to stock market index in oil importing countries. On the other hand, the findings revealed that global oil price is positively related to stock market index in oil exporting countries. The findings also reveal that interest rate, consumer price index, exchange rate and industrial production index impact stock markets in emerging economies for both oil exporting and importing countries. Stock market price index moves in opposite direction to interest rate and exchange rate in both oil exporting and oil importing emerging economies. Stock market price index moves in the same direction as industrial production index and consumer price index. The results have policy implications. As the results in this paper have shown, stock markets in emerging economies not only respond to changes in oil price but also to changes in economic fundamentals like interest rate, inflation rate, exchange rate and economic growth. Stock market indexes are often seen as leading economic indicators. Unforeseen shocks in global oil prices may disturb expectations related to economic growth in emerging economies. Therefore, central banks should use required monetary policy tools to offset the consequences of oil price shocks.

The effect of airline alliances on the performance of airline companies: The case of Star Alliance
Increasing competition rates, deregulations and liberalizations with the effect of globalization have led to numerous changes in aviation as well as in many sectors. Aircrafts have faced various changes in reaction to this changing and increasing competitive environment. Most airline companies within the world have sought new strategies to survive within the market and to protect themselves from the negative effects of these changes, and international airline alliances have emerged as a result of a situation. This study is a case on the Star Alliance, which is the world's biggest international airline alliance nowadays. The effects of Star Alliance on the performance of airline companies were examined. In arrange to shift the center of gravity of aviation from west to east and to make territorial differences, Air China, Turkish Airlines and Ethiopian Airlines were selected as the sample group among the member airlines of the Star Alliance. From a financial and operational point of view, assessments were made on various parameters based on the three years before and after the airlines joined the Star Alliance. As a result of the research, while the positive effects of Star Alliance on the performance of the pertinent airlines were observed in operational data, positive results were not observed in financial information.
Bir sivil toplum kuruluşunda iç denetim süreçlerinin incelenmesi: İlim Yayma Cemiyeti örneği
Kişisel menfaate dayanmayan, gönüllülük esasına bağlı faaliyet gösteren, toplum yararına kurulmuş olan, resmi kurum ve kuruluşların dışında kalan ve yasal topluluklar şeklinde tanımlanabilen sivil toplum kuruluşu (STK) oda, sendika, dernek ve vakıf vb. isimler altında sanat, kültür, eğitim ve sağlık gibi çeşitli alanlarda hizmet vermektedir. Yirminci yüzyılın sonlarına doğru ülkemizdeki STK sayısı gittikçe artmış, böylelikle hem topluma hizmette artış sağlanmış hem de devletin yeterli olmadığı alanlarda gönüllülük esasına dayalı faaliyetlerle devletin yükü hafifletilerek sorunların giderilmesi sağlanmıştır. Eğitim ve kültür alanında uluslararası standartlarda hizmet verme vizyonu ve ülkenin kalkınmasına, milli ve manevi değerlerini benimseyerek vatanına bağlı toplum oluşturacak eğitim ve kültürel faaliyetler yapma misyonuyla hareket eden İlim Yayma Cemiyeti (İYC), Türkiye'de eğitim alanında topluma hizmet sunan en eski ve en köklü sivil toplum kuruluşlarından biridir. Bu tez çalışmasında ülkemizde faaliyet gösteren ve önemli bir STK olan İYC'niniç denetim süreci incelenmiştir. İncelemeye temel olan sorunsal, Cemiyet'in iç denetim süreçlerinin ve mekanizmasının bilimsel bir incelemeye tabi tutulmamasıdır. Bu amaçla hazırlanan çalışmada iç denetim yöntemlerinden olan COSO örnek alınmıştır. COSO'ya göre İYC iç denetimini incelemek üzere Cemiyet'in denetim müdürü ile bir mülakat yapılmıştır. Ayrıca Kamu İç Denetim Standartları ile ilgili bilgi verilmiş olup bu standartlar İYC Denetim Yönetmeliği ile karşılaştırılmıştır.

The impact of sustainable development goals on the success of online crowdfunding campaigns: An analysis through natural language processing techniques
Online crowdfunding platforms are emerging as a significant alternative potential finance method, which are playing a critical role in mobilizing resources to achieve the United Nations Sustainable Development Goals (SDGs). This Study investigates the impact of SDG alignment on campaign success and, in addition, tries to find which individual sustainable development goals are more successful on a reward-based crowdfunding platform. By utilizing Natural Language Processing (NLP) techniques and Ordinary Least Squares (OLS) regression models on Kickstarter platform dataset of 138393 campaign launch between 2020 to 20204 to assess the relationship SDG alignment and campaign success, measured by the natural logarithms of the total pledged amount and the number of backers, while controlling for campaign duration, sentiment, project category, and geographical region. The findings show that SDG alignment has a statistically significant positive relationship with campaign success. Specifically, SDGs related to environmental such as SDG6 (Clean Water), SDG13 (Climate Action), and SDG14 (Life Below Water) significantly increase funding success. Conversely, campaigns focusing on basic needs such as SDG1 (No Poverty), SDG2 (Zero Hunger), SDG3 (Good Health), and SDG4 vi (Quality Education) tended to attract less funding and fewer backers on the Kickstarter platform. Sentiment in descriptions also contributes positively to the campaign's success, and campaign durations have a negative impact. Additionally, there are significant regional and category differences, with campaigns in the Asia-Pacific area and categories like Comics, Design, and Games performing better than those in North America and the Art category. These results offer practical implications for campaign creators, highlighting the strategic benefit of incorporating specific SDG themes, particularly environmental and justice-oriented ones, coupled with positive messaging and concise campaign timelines, while tailoring approaches to regional and categorical contexts to maximize crowdfunding success on reward-based platforms.
Film endüstrisinde pandemiyle değişen seyirci tercihleri
Bu çalışma, COVID-19 pandemisinin film endüstrisi üzerindeki etkilerini analiz etmek amacıyla gerçekleştirilmiştir. 2007-2023 yılları arasında vizyona giren 961 Hollywood yapımı film üzerinden yürütülen araştırmada; film türleri, yapım bütçeleri, seyirci ve eleştirmen puanları, açılış haftası hasılatları ve bütçeye oranla toplam hasılat gibi değişkenler üzerinden üç dönem (pandemi öncesi, pandemi dönemi ve sonrası) karşılaştırılmıştır. Nicel araştırma yöntemlerinin kullanıldığı çalışmada, ANOVA, Ki-Kare, korelasyon ve regresyon analizleriyle anlamlı farklar ve ilişkiler incelenmiştir. Analizler, pandemi sonrası dönemde film yatırım getirilerinin pandemi öncesine kıyasla düşüş yaşadığını ortaya koymuştur. Tür dağılımlarında aksiyon ve macera türlerinde artış; komedi ve animasyon türlerinde azalma gözlenmiştir. Eleştirmen ve seyirci puanlarında ise pandemi sonrası dönemde anlamlı bir yükseliş tespit edilmiştir. Regresyon analizine göre, açılış haftası hasılatı ve seyirci puanı gişe başarısını anlamlı biçimde öngörebilirken, eleştirmen puanlarının istatistiksel olarak anlamlı bir etkisi bulunmamıştır. Bulgularımız, pandemi sürecinin film endüstrisinde yalnızca geçici bir aksama değil, yapısal bir dönüşüm yarattığını göstermektedir. Çalışma, pandemi sonrası dönemin, endüstri için yeni bir evre olduğunu istatistiksel olarak ortaya koymakta; seyirci davranışlarının değişimi ve prodüksiyon stratejilerindeki dönüşüm gibi konularda literatüre özgün katkılar sunmaktadır.
