The Effects of Investor Behavior on Market Predictability
This study aimed to test the effects of investor behavior on the predictability of the market by testing CAPM estimation errors in negative growth period and growth period of the market. This study also aims to draw attention to the existence of some factors that may affect the CAPM estimation errors. Negative growth period is the period in which irrational behavior is likely to occur. Growth period is the period when irrational behaviors are less common. CAPM estimation errors calculated by jensen’s alpha, sharpe ratio, sortino ratio and treynor ratio were compared by T-Test and Mann-Whitney U Test during negative growth periods and growth periods.USA-S&P 500, Germany-DAX 100, England-FTSE 100, France-CAC All Tradable, Canada-S&P TSX, Japan-Nikkei 225 developed countries and their indices and India S&P BSE 200, China-SSE Composite, South Africa &-FTSE JSE African All Share, Turkey-BIST 100 developing countries and their indices included in the study. Between January 31,2005 and December 31,2018 monthly closing prices of the indices, monthly closing prices of stocks listed in consumer staples sectors and consumer discretionary sectors were used.As a result of the study, it has been observed that CAPM estimation errors calculated by jensen’s alpha and treynor ratio in consumer staples and consumer discretionary sectors in developed and developing countries do not differ during negative growth periods and growth periods of the market. It cannot be said that CAPM is more reliable or unreliable in negative growth periods compared to growth periods. It has been determined that CAPM estimation errors calculated by sharpe ratio and sortino ratio differ during negative growth periods and growth periods. It can be said that CAPM is less reliable in negative growth periods compared to growth periods
INVESTIGATION OF THE EFFECTS OF CARDIOVASCULAR AND AEROBIC EXERCISES ON BODY COMPOSITION AND BLOOD PARAMETERS IN SEDENTARY WOMEN
Aim: The aim of this study is to investigate the effects of 12-week cardiovascular and aerobic exercise on body composition and some blood parameters in sedentary women. Materials and methods: The selected 48 sedentary women participating at this study were attending B-Fit gymnasium in Giresun province. The sedentary women were splitted into two groups and subjected to the cardiovascular (n = 24) and the aerobic exercises (n = 24) one hour, three times a week. The intensity of the exercises was arranged according to the case that the heart rate is about 130-140 per minute. Measurements were made by adopting the same measurement methods before and after 12-week exercise there after the data were presented in tables using "student’s t-test" and "paired samples statistics". Results: Results have revealed that the values of body weight, body mass index, body fat percentage, cholesterol, triglyceride, LDL-C and waist-to-hip ratio of the subjects are decreased by the end of the 12-week workout. In addition, the HDL-C values of subjects are found to be increased in both groups (p <0.05 and p <0.001). Conclusion: The change in cardiovascular exercise group has been more significant in comparison with the aerobic exercise group. The cardiovascular and aerobic exercises performed in sedentary women have been found to trigger positive changes in body composition and blood parameters. Article visualizations
Calculation of the inequality of the middle income group: A case study of Afyonkarahisar
Bu çalışma Recep Kolukısa’ nın 2018 yılında Afyon Kocatepe Üniversitesi Sosyal Bilimler Enstitüsünde tamamladığı
“Orta Gelir Grubu Gelir Dağılımı Dengesizliğinin Hesaplanması: Afyonkarahisar Örneği” adlı Yüksek Lisans tezinden
üretilmiştir. Çalışmada kullanılan anket için Afyon Kocatepe Üniversitesi Bilimsel Araştırma ve Yayın Etiği Kurulu
tarafından 28.10.2016 tarih ve 2016/122 karar sayısı ile etik kurul onayı alınmıştır.Gelir dağılımı bir ülkede toplam GSYH’nin insanlar arasında ve üretim faktörleri arasında nasıl dağıldığını gösterir. Gelir dağılımı çalışmalarında toplam nüfus beş eşit gruba ayrılmaktadır. Ancak en yoksul %20 ile en zengin %20’nin toplam nüfus içindeki payının az olduğu, ortada yer alan grubun toplam nüfus içindeki payının ise göreli olarak fazla olduğu bilinmektedir. Orta gelir grubunun kendi içindeki gelir dağılımı eşitsizliğinin hesaplanması bu çalışmanın temel amacıdır. Eğer orta gelir grubunun kendi içindeki gelir dağılımı eşitsizliği, tüm ülkenin gelir dağılımı eşitsizliğinden önemli bir şekilde farklılık arz ediyor ise bunun izlenmesi gelir dağılımında adaletin sağlanması açısından önemlidir.
Bu çalışmada, anketle elde edilen veriler ve Türkiye İstatistik Kurumu verileri kullanılarak orta gelir grubu gelir dağılımı eşitsizliği hesaplanmıştır. Veriler SPSS programı ile analiz edilmiştir. Afyonkarahisar il merkezinde yapılan anket bulgularına göre, orta gelir grubunun Gini katsayısı 0.27 bulunmuştur. Türkiye İstatistik Kurumu verileri kullanılarak aynı grup için Gini katsayısı 0.17 bulunmuştur. Bulgular orta gelir grubu gelir dağılımı eşitsizliğinin toplam gelir dağılımı eşitsizliğinden önemli bir şekilde az olduğunu göstermektedir.Income distribution shows how the total GDP of a country is distributed among people and among production factors. Inincome distribution studies, the total population is divided into five equal groups. However, it is known that the share of the poorest 20% and the richest 20% in the total population is low, and the share of the middle group in the total population is relatively high. The main purpose of this study is to calculate the income distribution inequality of the middle income group. If the income distribution inequality with in the middle income group differs significantly from the income distribution inequality of the whole country, monitoring this is important in terms of ensuring justice in income distribution.
In this study, the middle income group’s income inequality is calculated by using questionnaire data and the Turkish Statistical Institute data. The data were analyzed with the SPSS program. According to the findings of the questionnaire conducted in Afyonkarahisar city center, the Gini coefficient of the middle income group was found 0.27. The Gini coefficient for the same group was found 0.17 by using the Turkish Statistical Institute data. The findings show that middle income group’s distribution inequality is significantly less than total income distribution inequality

Obtaining and analysis of gluten-free toothpaste from acorn for celiac patients
Günümüzde giderek yaygınlaşan çölyak hastalığı ile ilgili araştırmalara bakıldığında glütensiz yiyeceklerin ön planda olduğu görülmektedir. Çölyak hastalığı ve glüten duyarlılığı olan bireylerin sağlıklı bir yaşam sürdürebilmesi için beslenmelerinde olduğu gibi kişisel bakım ürünlerinde de glüten bulunmamalıdır. Meşe palamudu, meşe ağacının (Quercus) çeşitli türlerinden biridir. Ülkemiz, meşe ağacı cinsinin yayılış ve tür dağılımı bakımından en zengin merkezlerden birini oluşturmaktadır. Meşe ağacının meyvesine halk arasında palamut denilmektedir. Palamut, pelit ve kadeh (kupula) olmak üzere iki kısımdan oluşmaktadır. Meşe palamudunun antioksidan özelliği vardır ve glütensiz olması önemli özelliklerindendir. Bu araştırma kapsamında çölyak hastalarının kullanımına uygun glütensiz diş macunu formülasyonunun geliştirilmesi için ham madde olarak meşe palamudu kullanılmış, elde edilen diş macununun glütensiz olduğu analiz ile kanıtlanmış ve antibakteriyel etki göstermesi incelenmiştir.When the researches on celiac disease, which are becoming more and more common today, are examined, it is seen that gluten-free foods are at the forefront. In order for individuals with celiac disease and gluten sensitivity to lead a healthy life, gluten should not be present in personal care products as well as in their diets. The acorn is one of the several species of the oak tree (Quercus). Our country is one of the richest centers in terms of the species distribution of the oak tree genus. The fruit of the oak tree is called acorn among the people. Acorn consists of two parts: valonia and cup. Having antioxidant properties and being gluten-free is one of acorns’ important features. Within the scope of this research, the use of acorn as a raw material for the development of gluten-free toothpaste formulation suitable for the use of celiac patients, the proof that the obtained toothpaste is gluten-free with analysis and its antibacterial effect were examined
