Dayi, Faruk; Kukus, Bayram Ali; Esmer, Yusuf
Purpose - The aim of this study is to analyze managers’ financial management behaviors (cash management, credit management, savings-investment and insurance). Financial management behavior, therefore, plays a key role in the success of managers and organizations. Financial management behavior refers to managers' individual and organizational decisions on and practices in financial matters such as cash, loans, savings, investments and insurance.Design/methodology/approach - Study sample consisted of 85 managers of KOSGEB (Small and Medium Enterprises Development Organization, Turkey). Data were collected using survey method. Data were analyzed using SPSS version 22. Frequency, percentage, mean, standard deviation, reliability, factor analysis and ANOVA were used.Findings - Managers’ financial management behaviors differ by experience, income and education level. The higher their experience, income and education level, the higher their insurance sensitivities. Managers have high tendency to credit management and cash management behaviors, moderate tendency to savings-investment behaviors and medium to low tendency to insurance behaviors. This result indicates that managers do not attach enough importance to insurance, in other words, they are not cautious enough about insurance.Discussion - Participants’ financial management behaviors differed by experience, income and education level but not by gender, marital status, age and credit card use. This study is important in the sense that it is one of the fewest studies addressing financial management behavior.

Dursunoğlu, İsmail
Political culture is the sum of the political structure, traditions and tendencies that determine the individual's or society's political thought and behavior. In its simplest terms, the culture is the political direction. In the formation of political cultures are the role of individuals, their beliefs, attitudes and actions in relation to the political system. Each region's political culture emerges as a factor that determines voter preferences and therefore election results. Political culture is a concept that can be explained by different methods and studies. At the beginning of these studies, must to survey is carried out on an area to evaluate the results. However, in this study, it is carried out political culture analysis on the results of elections which are accepted as a result of political culture. The results of the general elections between 1991 and 2015 are presented in the study by being make a comparison with the example of Yozgat-Bayburt. The aim of the study is to make sense of the political culture of the province through the election results evaluated as the final result of political culture. In the study, which is a method of evaluating the election results, an approach towards the cause has been highlighted. Briefly, as a result of the political culture, the voter preferences were taken to the center of the study and the political culture was deduced from the deductive results. The hypothesis that ”the political culture of the two provinces is similar on a conservative-nationalist basis“ accepted as a result of the study and as a result determined the similarities and differences for the political culture of the two provinces.

Ucan, Izzet; Ozan, Murat
The aim of this study is to determine the speech anxiety levels of physical education and sports department students and to examine them in terms of different variables. The research was carried out with 202 students (66 female and 136 male) studying in different departments of Erzurum Ataturk University Faculty of Sports Sciences in 2108/2019 academic year. The data related to the study were collected by Speech Anxiety Scale developed by Yaman and Sofu (2013) and the Demographic Information Form determined by the researchers. Frequency distribution was used to determine the students' demographic characteristics, Independent Samples T-test was used to examine the differentiation between two independent variables and speech anxiety and One-Way ANOVA analysis was used to examine the differentiation between more than two variables and speech anxiety. All these tests were analyzed in SPSS 21 package program and the significance level was accepted as p <0.05. As a result of the research, it was determined that there was no significant difference between the students' demographic characteristics, sporting activities and speech anxiety levels. Although there was no significant difference, it was also observed that the male students' total score of speech anxiety was lower than that of female students numerically. It was observed that, regarding the students' family structure variable, those who had a fragmented family, who had a monthly personal income level of over 1501 TL, who studied in the department of management, did sports activities and performed both sports as regards their sports activity type, had numerically a low level of speaking anxiety when compared to other variable groups. In the light of these results, it is suggested that students should be encouraged to participate in sports activities and to engage in different social activities in order to reduce their speech anxiety levels. Apart from this study, it is recommended to investigate using different variables and to determine the variables that may have a positive or negative effect on speech anxiety.

Güzel Korver, Semra; Keskin, Savas
This study consists of a cultural analysis of social media usage as a platform for self-representation and socio-digital compensation of Roman users who are exposed to problems in terms of representation and recognition due to their position as a minority group in Turkey. The aim of the study, which examines the identity building of a group of Romany users organized on Facebook under the name of Romany Research Center, is to determine the functions, maneuvers and cultural aspects of the self-representation practices of the Romany ethnic identity under socio-digital conditions and to understand the ways in which digital building actions transform the relationship between identity and otherness in the context of Romany users. In the study, which focuses on representation of ethnicity and cultural identity, the netnography method, defined as social network ethnography, was used to analyze the cultural interfaces and shares on the page. Within the framework of the method, the shares on the community page were coded as cultural layers and identity generators, and a wide-ranging observation and document review process was undertaken. The cultural codes interpreted from a descriptive perspective show that the members who share the Romany identity think about the perception of being `We' together with the Turkish national identity and construct another identity known as Gaco (Non-Romany). The findings of the study reveal that the organization/composition of proving laundering and innocence is dominant instead of autonomous and positive constructs in the socio-digital construction process of the Romany ethnic identity. In this case, it may be argued that the community members continue to create an awareness of their problems by closing the information gap in a sense by freely displaying their positive identities that the media ignores.

1917 was a turbulent year for Russia. Successive events in the country led to the collapse of the tsarist regime. The administration was taken over by a provisional government, but its actions did not satisfy the revolutionary organizations. Especially, the Bolshevik Party did not compromise with the government and acted against it. Moreover, accusing other parties on cooperating with the government they attempted riot in July, but failed. It is generally focused on October Revolution in studies about the activities of the Bolsheviks in Turkey. This is because they succeeded in the October revolution. But they are known to have attempted riot and wanted to overthrow the government even before October. However, it was identified that this issue did not take part in the studies. Therefore, in this study Bolsheviks' riot attempt in July was examined and focused on how they were prepared and how they organized their supporters.

On October 29, 1914, after the bombing of the Black Sea coast of Odessa, Sevastopol, Feodosia and Novorossiysk by two Ottoman naval vessels, the Russian government porclaimed that diplomatic relations with the Ottoman state had been cut off and immediately called the Russian embassy delegation in Istanbul back to the country. On November 2, Tsar Nikola issued a manifesto and declared war against the Ottoman Empire and ordered the Caucasus army to attack the Turkish army by crossing the border. Thus, the Ottoman Empire actually entered the First World War. After Russia declared war against Ottoman Empire , clashes between the two sides began in the Eastern Anatolia region. The main aim of Russia was the Capture of Erzurum which was also the base of the III. Corps of the Ottoman Empire . The Ottoman Empire, aware of this situation, prepared a plan. According to this plan, Russia will be firstly removed from the region and so Kars and Ardahan will be rescued. Later on, Baku will be recovered by moving to the South Caucasus and all Turkish-Islamic peoples living under Russian domination will be encouraged to rebel against Tsarism. In order to implement this plan, the Ottoman Empire decided to carry out a risky operation in December 1914. This operation, known in history as Sarikamis Operation, lasted for about 15 days and ended with great defeat for the Ottoman Empire. The information given by the Russian sources on the Sarikamis Operation, which still has great debate on today, is undoubtedly very important. In this study, wiew and aspects of Russian press and literature beyond archive sources towards Sarikamish Operation was examined.

The main aim of this study is determining which consumption motives and personal and social factors affect organic food buying decisions. Ajzen's Planned Behavior Theory (TPB) is used to explain consumers' organic food selection behaviors. In addition, the moderating role of uncertainty about organic foods and the mediating role of the price of organic foods were tested. Data were gathered via a survey of consumers of organic foods in Turkey. The research model was tested by Structural Equation Modeling (SEM) via Smart PLS3. The findings showed that consumptions motives of healthiness, easiness, mood, and convenience-price of organic foods motivate consumers to buy organic foods. In addition, environmental concern and negative emotions influence on attitudes towards organic foods and purchase intentions. On the other hand, subjective norms and self-monitoring do not influence attitudes towards organic foods and subsequent purchase intentions. Uncertainty has a moderating effect on the relationship between attitudes and purchase intentions whereas price has no mediating effect on the relationship between attitudes and purchase intentions.

Kamiloglu, Hakan Alper; Sadoglu, Erol
Failure surfaces are very effective in active lateral earth thrusts acting on cantilever retaining walls. The intersection of failure surface and cantilever retaining wall should be taken into account for determination of active earth thrust. Calculations of lateral earth thrusts vary for two different cases, short heel or long heel, based on the intersection of cantilever wall and failure surface. However, the common methods are devoted to a particular case (long heel or short heel). This study intended to suggest a new lateral earth thrust method that is applicable to cantilever walls with a short heel or long heel using the limit-equilibrium approach. For this purpose, an earth thrust-maximization algorithm was prepared and coded by using Matlab Environment to determine active earth thrust coefficients and failure surface inclination angles occurring behind a cantilever wall in an active case. Also, the failure surfaces occurring behind model cantilever walls and the failure cases were examined experimentally by using particle image velocimetry (PIV) analysis. Consequently, long-heel and short-heel cases and the effective parameters on the cases were investigated analytically and experimentally. (C) 2019 American Society of Civil Engineers.

This study was conducted to investigate the effect of various stabilizers on textural properties of set yogurt. Yogurt samples were prepared by using seven various stabilizers such as sodium caseinate, gelatin, carrageenan, xanthan gum, guar gum, locust bean gum and native corn starch. Control group samples were produced without using stabilizer. Textural analyzes were made with a TA-XT2i texture analyzer. As a result of the statistical analysis, it was determined that stabilizer and storage time had a significant effect (p<0.01) on all texture parameters of yogurt samples, the relaxation force values were not affected by only storage period (p>0.05). In conclusion, Nacaseinate was the most suitable stabilizer for yogurt texture compared to all stabilizers. These findings may contribute to the selection of stabilizer material or preparation of stabilizer mixtures that can be used in the production of set type yogurt for developing different textural parameters.
