This study aims to determine the impact of crisis perception on consumer purchasing behaviors during the Covid-19 period. To this end, a survey has been conducted with citizens who are in quarantine and hold a decision-making position in making purchases. The study’s hypotheses were tested with correlation and multiple regression. These analyzes pointed out that crisis perception among consumers during the Covid-19 and sparingness and cautiousness, which are the sub-dimensions of crisis perception had positive and significant effect on purchasing behavior; however, the study determined that concern for the future sub-dimension did not have positive and significant effect on purchasing behavior. The results of the difference tests revealed that only wage restrictions caused a significant difference in crisis perception.

Bu çalışmanın amacı bilinçli tüketici kavramının tüketici zihnindeki algısının metaforlar üzerinden değerlendirilmesinin yapılmasıdır. Sürdürülebilir bir yaşam döngüsünün kurulması için anahtar kavramlardan biri olan bilinçli tüketicinin dolayısıyla bilinçli tüketim faaliyetinin tüketici konumunda olan bireyler tarafından nasıl anlamlandırdığını tespit edilmek amaçlanmıştır. Bu nedenle nitel araştırma desenlerinden olgu bilim yaklaşımının tercih edildiği bu çalışmada evrenin Türkiye olarak seçildiği 109 tüketiciye ulaşılmıştır. Tüketicilerden “Bilinçli tüketici……………………gibidir/benzer. Çünkü…………” cümlesini metaforlar ile tamamlanmaları ve nedeninin açıklanması istenmiş, elde edilen veriler içerik ve betimsel analiz yöntemleri kullanılarak analiz edilmiştir.

Companies are looking for ways to access capital from developed markets instead of local markets to find financing. While some companies use debt instruments for this purpose, others use equity financing methods. One of the techniques used in equity financing is the simultaneous registration of shares on national and foreign stock exchanges, also known as the dual-registration method. Investors entering international markets by investing in dual-registered shares is important for companies to gain capital. However, another important issue for those investing in stocks is the ability to gain capital through accurate prediction of price movements. The aim of this study is to predict the prices of Turkcell stocks traded on Borsa Istanbul and the New York Stock Exchange (NYSE) using machine learning and deep learning methodologies. The results of the analyses conducted with the Random Forest Regressor and Long Short-Term Memory algorithms, which are machine learning and deep learning algorithms, respectively, showed that both algorithms exhibited a lower error rate in predicting the closing prices of Turkcell stocks on the NYSE.

The purpose of this study is to examine the mediating role of advertising expenditures in the impact of brand value on financial performance. The study sample consists of firms that have been continuously ranked among Turkey’s 100 most valuable and powerful brands by Brand Finance for 2013-2018 and have been continuously listed in Borsa Istanbul 100 for the same period. The data used in the research are the companies’ annual brand values, advertising expenditures, and financial performance indicators, namely, change in sales and changes in profitability. The analyses were carried out with the help of structural equation models using AMOS.21 software. Results indicate that the brand value affects change in sales, which is one of the indicators of financial performance, and advertisement expenditures play a mediating role in between. However, it has been determined that brand value does not significantly explain the change in profitability, the other financial performance indicator used. Bu çalışmanın amacı, marka değerinin finansal performans üzerindeki etkisinde reklam harcamalarının aracı rolünü incelemektir. Çalışmanın örneklemini, Brand Finance tarafından 2013-2018 yılları arasında açıklanan Türkiye’nin en değerli ve en güçlü 100 markası içinde sürekli olarak yer alan ve aynı zamanda Borsa İstanbul 100 Endeksi’nde kesintisiz olarak işlem gören firmalar oluşturmaktadır. Araştırmada kullanılan veriler, firmaların yıllık marka değerleri, finansal performansın göstergelerinden olan satıştaki değişim ve kârlılıktaki değişim tutarları ile reklam harcamalarıdır. Analizler AMOS.21 programı kullanılarak, yapısal eşitlik modeli ile gerçekleştirilmiştir. Çalışma kapsamında, marka değerinin finansal performans değişkeninin göstergelerinden biri olan satışlardaki değişim üzerinde etkisi olduğu tespit edilmiş, ayrıca bunun üzerinde reklam harcamalarının aracılık etkisinin bulunduğu da belirlenmiştir. Ancak marka değerinin finansal performans göstergelerinden kârlılıktaki değişimi açıklamada anlamlı bir etkiye sahip olmadığı tespit edilmiştir.

Sustainable campuses are spaces where universities can contribute to a sustainable future by implementing environmentally, social, and economic principles. Nowadays, it is vital that campuses serve not only as centers of education but also as small cities that are the application areas of a sustainable mindset. Therefore, educational institutions should implement sustainable practices on campuses to fulfill their responsibilities to society and contribute to a sustainable future. The aim of this study is to examine the perceptions of students studying at two state universities in Konya, Turkey, regarding the concept of “sustainable campus”. In this study, metaphor analysis and semi-structured interview methods, qualitative methods, were used together. Combining these two methods provided an in-depth understanding of both conceptual and emotional dimensions. According to the metaphorical findings, participants associated the concept of a sustainable campus with environmental, economic, social, and cultural dimensions. Social sustainability was the dimension most frequently emphasized by the participants. Participants generally defined a sustainable campus with metaphors such as “nature” and “growth”, but they stated that they had difficulty producing metaphors due to the abstract nature of the concept. According to the interview findings, students had a general awareness of the concept of a sustainable campus, but this awareness was mostly limited to concrete practices such as environmental management and energy saving. Participants emphasized only the environmental aspects of sustainable campuses, whereas they did not have enough information about other aspects such as social and cultural sustainability. It was found that students, especially in engineering and technical departments, associate the concept of sustainability with infrastructure and energy efficiency, but have low awareness of the sustainability of social functioning on campus. The findings reveal that universities should not only limit the sustainable campus concept to environmentally friendly practices and develop policies to support social and cultural sustainability.
