In the study, there is a need to choose among the alternatives on the axis of various criteria within the framework of the problem. Handling the data used in the study within the scope of August 2020 represents the actuality of the study. Furthermore, the AHP (Analytic Hierarchy Process) method as a Multi Criteria Decision Making method was used to analyze the data, supported by seven criteria and seventeen alternatives beyond the studies of the authors presented in the literature review, and this method was applied in a different area involving individual’s selection within the framework of products of a company. In this context, the AHP method allowed the individual to solve the problem by addressing it with Super Decisions software. In order to determine the preferences of the individual subject to the study within the scope of decision making, the criteria previously included in the studies of different authors were examined. And the data obtained from the official website of the automobile company, which is the choice of the individual, were evaluated with the decision maker (individual), thus an original list with seven distinct criteria was created for the study with literature support. In this context, it is possible to address the boundaries of the study through a single individual. Alternative cars for the individual's car purchase problem were also revealed with the data obtained from the company's relevant website, and selection alternatives were formed of seventeen different versions for three distinct passenger car models. Accordingly, the scope of the study was explained with the relevant vendor company. A broad list of seven criteria and seventeen alternatives used in problem analysis contributes to the literature with the originality in dealing with the criteria and alternatives.","PeriodicalId":388632,"journal":{"name":"Journal of Yaşar University","volume":"32 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116650924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, independent audit reports and weekly Capital Market Boards of Turkey (CMB) Bulletins were examined within the scope of the study, and cases of applying to fraudulent financial reporting practices were determined. In this context, 127 financial statements and independent audit reports of relevant periods were examined. In the study, 12 financial ratios used in literature to explain fraudulent financial reporting and 10 methods based on data mining were used. According to research findings, all models based on data mining used within the scope of the study were more than 70% successful in correctly classifying financial statements that are considered to have fraud risk and financial statements that are considered to have no fraud risk, and the most successful methods are models established with J48 and Deep Learning methods.","PeriodicalId":388632,"journal":{"name":"Journal of Yaşar University","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125840031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to this complex structure, the process of predicting the future behavior of time series is a very challenging field for researchers. In this study, a comprehensive feature engineering process was applied to estimate the daily return direction of the BIST 100 index and models were carried out using different machine learning algorithms. The features to be taken as input to the models were extracted depending on the summative statistics of the series, the additional characteristics of the sampling distribution, and the observed dynamics reflecting the non-linear/complex structure of the series and it was shown that the classification performances are quite high without using exogenous variables. In addition the durability of the predictions performances was investigated using different training-test ratios.","PeriodicalId":388632,"journal":{"name":"Journal of Yaşar University","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128456518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, the human capital factor has become very important factors in the development of countries. In this context education, which is an important element of human capital, and its effects on development are among the most investigated topics among economists. Thus, it has been proven with the many theoretical and empirical studies that education has positive effects on development. In this study were examined the role and effects of education on the development of the TRA2 region, which includes Turkey's Ağrı, Kars, Iğdır and Ardahan provinces. As a result of the analysis covering the 2008-2018 period, it was determined that the correlation between increasing education level and per capita income levels to increase. These results strongly prove the importance of education for the development of both the region and the country.","PeriodicalId":388632,"journal":{"name":"Journal of Yaşar University","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134121321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
