The relationship between the adolescents' exposure to peer victimization and their age, parental style and self-image
(Turkish Psychologists Assoc, 2006) Oezen, Dilek Sirvanli
The objective of this study is to determine whether the age, the perceived parenting style and the self-image of the individual contribute to his/her exposure peer victimization as well as to the prediction of the different types of peer victimization for both girls and boys. The sample of the study consists of 805 students: 381 girls and 484 boys, all of whom study at the second level of private primary education schools and high school's 6th, 7th, 9th and 10th grades in Istanbul. However, as some of the scales were not filled out properly, hence the sample size decreased to 314 and to 308 for boys and girls respectively. In the study, 'The Peer Victimization Scale' to determine the level of their exposure to peer victimization, 'The Parenting Style Scale' to identify, the perceived parenting styles of the subjects and 'The Offer Self-Image Scale' to reveal the self-images of the participants, were used as instruments for data assessing. Results show that the peer victimization both girls and boys encounter at school is significantly influenced by the age, the perceived parenting styles and the self-image of the individual. Findings are discussed within the framework of the related literature.
University evaluation-selection: a Turkish case
(Emerald Group Publishing Ltd, 2006) Yamamoto, Gonca
Purpose - The purpose of this study is to examine the university selection criteria of students for better university management with the use of marketing tools. Design/methodology/approach - This study consists of a survey on students attending a foundation university in Turkey. The questionnaire method has been chosen in order to determine the important criteria having an impact on the student views towards university selection. The students had been admitted to a foundation university in the 2005-2006 period when within the same universities various departments were included in the study. Findings - The results indicate student evaluation and selection criteria in this period of time. Practical implications - This paper examines the criteria that affects the selection of students and, in detail the students' point of view towards the university evaluation and selection in Turkey. This will help the university manager's decision making on the marketing tools they use. Originality/value - Selecting a university is a long-term commitment and a very important decision for the high school students and/or graduates. Academic, social, physical factors and facilities are some important criteria for university selection. This study concerns the importance of these criteria in detail.
Intrusive autobiographical memory and its depressive theme on high depressive symptomatology
(Turkish Psychologists Assoc, 2006) Tosun, Ahmet
The research investigates the intrusion and depressive content of the autobiographical memory (AM) that associated with depressive self cognition. 493 students from different universities in 2004-2005 academic years participated in the study. Cognition Check List, Depressive Content Evaluation Form, Impact of Event Scale and Beck Depression Inventory were applied. Results showed that, depressives evaluated their own self at the event as more 'worthless, 'unlovible' and 'inefficient'. They evaluated the others at the event as more 'distrustful, 'rejective' and 'unsupportive' and the event as more 'unchangeable' in future than non-depressives. Concerning AM associated with depressive cognition, depressives reported more intrusion of the AM than non-depressives. It is considered that depressive persons' AM associated with depressive cognition may be a self defining memory. As a result, it is suggested that AM is an important material and context in changing procedure of depressive cognitions in CBT.
The end results of general relativity theory via just energy conservation and quantum mechanics
(Springer/plenum Publishers, 2006) Yarman, Tolga
Herein we present a whole new approach that leads to the end results of the general theory of relativity via just the law of conservation of energy (broadened to embody the mass and energy equivalence of the special theory of relativity) and quantum mechanics. We start with the following postulate. Postulate: The rest mass of an object bound to a celestial body amounts less than its rest mass measured in empty space, and this, as much as its binding energy vis-a-vis the gravitational field of concern. The decreased rest mass is further dilated by the Lorentz factor if the object in hand is in motion in the gravitational field of concern. The overall relativistic energy must be constant on a stationary trajectory. This yields the equation of motion driven by the celestial body of concern, via the relationship e(-alpha)/root 1-nu(2)(o)/c(o)(2) = constant, along with the definition alpha = GM/rc(o)(2); here M is the mass of the celestial body creating the gravitational field of concern; G is the universal gravitational. constant, measured in empty space it comes into play in Newton's law of gravitation, which is assumed though to be valid for static masses only; r points to the location picked on the trajectory of the motion, the center of M being the origin of coordinates, as assessed by the distant observer; v(o) is the tangential velocity of the object at r; c(o) is the ceiling of the speed of light in empty space; v(o) and c(o) remain the same for both the local observer and the distant observer, just the same way as that framed by the special theory of relativity. The differentiation of the above relationship leads to GM/r(2)(1 - v(o)(2)/c(o)(2)) = v(o) dv(o)/dr or, via v(o) = dr/dt, GM/r(2) (1- v(o)(2)/c(o)(2)) r//r = d (v) under bar (o)/dt; (r) under bar is the outward looking unit vector along r; the latter differential equation is the classical Newton's Equation of Motion, were v(o), negligible as compared to c(o); this equation is valid for any object, including a light photon. Taking into account the quantum mechanical stretching of lengths due to the rest mass decrease in the gravitational field, the above equation can be transformed into an equation written in terms of the proper lengths, yielding well the end results of the general theory of relativity, though through a completely different set up.

(Iop Publishing Ltd, 2007) Kholmetskii, A. L.; Yarman, T.
In this paper, we analyse a number of paradoxical teaching problems of classical electrodynamics, dealing with the relativistic transformation of force for complex macro systems, consisting of a number of subsystems with nonzero relative velocities such as electric circuits that change their shape in the course of time.
Integrating Hoshin Kanri and the Balanced Scorecard for strategic management: The case of higher education
(Routledge Journals, Taylor & Francis Ltd, 2007) Asan, Seyda Serdar; Tanyas, Mehmet
This paper suggests a methodology that focuses on the vision and the deployment of strategies throughout the organization by merging Balanced Scorecard and Hoshin Kanri. The authors believe that combining a performance-oriented approach like the Balanced Scorecard with a process-oriented approach like Hoshin Kanri creates synergy. The proposed methodology begins with the selection of strategic objectives according to the Balanced Scorecard perspectives, which is followed by the generation of the strategy map. The developed strategies are then deployed down to implementation plans which are reviewed by Hoshin Kanri, and the outcomes are evaluated by utilizing both. tools. The implementation of the proposed methodology is illustrated based on an Engineering Management Graduate Program (EngMan). Finally, using the proposed methodology, implementation plans for the management of EngMan are realized, facilitating EngMan to attain its vision in the long term.
ATTITUDES OF STUDENTS TOWARD COUNTRY-OF-ORIGIN AND AUTO BRAND IMAGES
(Univ Belgrade, Technical Faculty At Bor, 2007) Aydin, K.; Say, A. T.; Ustaahmetoglu, E.; Yamamoto, G. T.
Personal and environmental factors determine the image of a company or a brand, which appears as an attitude of the perceiver. The attitudes of people against the products, countries and concepts are directly influential in their purchasing decisions. The objective of this research is to define whether there is a relation between the image of a country and that of the product. This study measures the attitudes of Turkish consumers against five countries and automobile brands from each of these countries. This study aims to identify whether there are any differences between the images of the countries and the respective automobile brands.

Determination of micro-elements in surface water resources
(destech Publications, inc, 2007) Sahmurova, Aida; Ongen, Atakan; Ozbas, Emine Elmaslar; Balkaya, Nilgun
The basic resources of microelements that are essential for human life. However, in larger or lower amounts, they may become important and critical. They may accumulate in biological systems and become a significant health hazard. Biochemical and physical adaptation of microorganisms is related to geophysical properties and the environmental factors in the surrounding habitat. Therefore many research studies have been conducted dealing microelements and their effect on ecosystems. In this study, heavy metal contamination in the samples taken from surface water resources in the Republic of Azerbaijan were examined. During the study, concentrations of 7 microelements (I, F, Cu, Co, Mn, Zn, Mo) in surface waters were determined. As microelement concentration of the water in the water springs varied from region to region due to the ion structure of the water, microelement concentrations are shown as minimums and maximums and the correlation between above-mentioned microelements was determined. This correlation was taken into account as an additional factor for occurrence of endemic illnesses.
Modelling Seasonality - An Extension of the HEGY Approach in the Presence of Two Structural Breaks
(Savez Ekonomista Vojvodine, 2008) Tasseven, Ozlem
In this paper the HEGY testing procedure (Hylleberg et al. 1990) of analysing seasonal unit roots is tried to be re-examined by allowing for seasonal mean shifts with exogenous break points. Using some Monte Carlo experiments the distribution of the HEGY and the, extended HEGY tests for seasonal unit roots subject to mean shifts and the small sample behavior of the test statistics have been investigated. Based on an empirical analysis upon the conventional money demand relationships in the Turkish economy, our results indicate that seasonal unit roots appear for the GDP deflator, real M2 and the expected inflation variables while seasonal unit roots at annual frequency seem to be disappear for the real M 1 balances when the possible structural changes in one or more seasons at 1994 and 2001 crisis years have been taken into account.
Embedding theorems in B-spaces and applications
(Shanghai Scientific Technology Literature Publishing House, 2008) Shakhmurov, Veli B.
This study focuses on the anisotropic Besov-Lions type spaces B-p,theta(l)(Omega; E-0, E) associated with Banach spaces E-0 and E. Under certain conditions, depending on l=(l(1),l(2),..., l(n)) and alpha=(alpha(1), alpha(2),..., alpha(n)), the most regular class of interpolation space E-alpha between E-0 and E are found so that the mixed differential operators D-alpha are bounded and compact from B-p,theta(l+s) (Omega; E-0, E) to B-p,theta(s) (Omega; E-alpha). These results are applied to concrete vector-valued function spaces and to anisotropic differential- operator equations with parameters to obtain conditions that guarantee the uniform B separability with respect to these parameters. By these results the maximal B-regularity for parabolic Cauchy problem is obtained. These results are also applied to infinite systems of the quasi-elliptic partial differential equations and parabolic Cauchy problems with parameters to obtain sufficient conditions that ensure the same properties.
Exploring the role of metacognition in obsessive-compulsive and anxiety symptoms
(Pergamon-elsevier Science Ltd, 2008) Irak, Metehan; Tosun, Ahmet
This study tests three hypotheses, predicting first that metacognition is highly correlated with anxiety and obsessive-compulsive (O-C) symptoms, second that it mediates the relationship between O-C symptoms and anxiety, and third that the meta-cognitive predictors of anxiety are different from the meta-cognitive predictors of O-C symptoms. The sample of the present study was 850 students selected from various universities in Turkey. Significant correlations between metacognition, O-C symptoms and anxiety were observed. Also, mediation analysis confirmed that metacognition fully mediated the relationship between O-C symptoms and anxiety. Consistent with our hypothesis, trait anxiety and O-C symptoms had different meta-cognitive predictors. Although, we expected that meta-cognitive beliefs would vary based on the sub-type of O-C symptoms, meta-cognitive beliefs did not differ according to the O-C symptom subtypes. We discussed results with reference to the literature of meta-cognition, anxiety and O-C symptoms. (c) 2008 Elsevier Ltd. All fights reserved.
Microelements in food materials consumed by children in boarding schools and day nurseries
(destech Publications, inc, 2008) Sahmurova, Aida; Babayeva, Sabina
The basic resources of microelements that are essential for human life are food materials. However, in larger or lower amounts, they may become more important and critical. They may be accumulated in biological systems and pose a significant hazard to health. Biochemical and physical adaptation of microorganisms are related to geophysical properties and the environmental factors in the surrounding habitat. Therefore, many research activities have focused on microelements and their effect on ecosystem. In the Republic of Azerbaijan specialized research activities have been carried out since 1950s. This study has been carried out in the Kuba-Khachmas and Sheki-Zaqatala regions where endemic goiter is a critical health disease. In order to compare the effect of microelements, their level in a blank region, Absheron peninsula, was also investigated. 160 samples of consumed food materials in the regions were collected from boarding and nursery schools. Iodine, fluorine, copper, cobalt, manganese, zinc and molybdenum levels were determined for each sample Although for almost each microelements a large range was observed between minimum and maximum levels, the results showed that the soil character in the studied areas had lower microelement amount levels than required for vital activities.

In this study, the vibration and air shock measurement results are given in order to evaluate the environmental results of excavation works with explosions executed in the agrega quarry by Ilkdal Mining Industry Ltd. Corp. which is working in the borders of Kemerburgaz region of Eyup county in istanbul city on producing agrega. The blasting pattern, explosive material charge parameters and vibration measurement results of each blastings are recorded. In the research, the frequency and particle velocity quantities of 31 events of overall 6 different blastings which are take place all in the area which is in question in different times are determined with recording devices. Then, in order to determine particle velocity, scaled distance and particle velocity data are analysed fort he area in question. During this analysis, distance equality with square root and scale which is widely used in literature is used. In the end of evaluation, for the area in question, between the scaled distance and particle velocity, with a prediction tolerance of 95%, an empirical connection with a good correlation (r=0,75) is obtained and recommended. By using this connection, the highest particle velocity, tables which cotain the prediction of the maximum charge quantities per delay are given and some suggestions which should be taken in care in the next works are put forward and these will provide practical easines in usage in future blastings. To compare and estimate the impact levels of the results obtained from the area in question on the surrounding buildings and institutions; with taking frequencies of particle velocity components in consideration, are evaluated according to universally accepted German DIN 4150 Norm, USBM Norm and T.C.

(int Scientific Conference Sgem, 2008) Ozer, Umit; Kahriman, Ali; Aksoy, Mehmet; Karadogan, Abdulkadir; Adiguzel, Deniz
This paper presents the results of ground vibration measurements and environmental issues occurred on tunnel blasting activities during Kavacik-Beykoz waste water tunnel construction under a residential area in Istanbul, Turkey. Within the scope of the study, the blasting pattern of tunnel was engineered by using Tunnel 2000 design software. 5 events in 5 shots at S2 shaft tunnels, , 6 events in 6 shots at S4 shaft tunnels,, 32 events in 32 shots at S6-shaft tunnels and, 7 events in 7 shots at S7 shaft tunnels were recorded.. The particle velocities and frequencies associated with 50 shots during the advancement of the tunnels were monitored and analyzed by vibration monitors at the test site. Scaled distance and peak particle velocity data pairs were analyzed statistically. During the statistical analysis, three different predictor equations widely used in the literature were used to predict peak particle velocity (PPV) and the results and comparison of the predictor equations are presented in this paper. As a result of this analysis, empirical relationships between Scaled distance and peak particle velocity for these regions were established with higher correlation coefficients. Finally, the particle velocities and frequency values of all blast events were evaluated according to T.C. Ministry of Environment and Forest's Regulation of Management and Evaluation of Noise, The United Sates Bureau of Mines (USBM) and German DIN 4150 Norms in order to predict, and compare the influence grades to the neighboring buildings, and structures.
Carleman estimates and unique continuation property for the anisotropic differential-operator equations
(Science Press, 2008) Shakhmurov, Veli B.
The unique continuation theorems for the anisotropic partial differential-operator equations with variable coefficients in Banach-valued L (p) -spaces are studied. To obtain the uniform maximal regularity and the Carleman type estimates for parameter depended differential-operator equations, the sufficient conditions are founded. By using these facts, the unique continuation properties are established. In the application part, the unique continuation properties and Carleman estimates for finite or infinite systems of quasielliptic partial differential equations are studied.
Embeddings and Separable Differential Operators in Spaces of Sobolev-Lions type
(Maik Nauka/interperiodica/springer, 2008) Shakhmurov, V. B.
We study embedding theorems for anisotropic spaces of Bessel-Lions type H-p,gamma(l) (Omega; E-0, E), where E-0 and E are Banach spaces. We obtain the most regular spaces Ea for which mixed differentiation operators D-alpha from H-p,gamma(l)(Omega; E-0, E) to L-p,L-gamma(Omega; E-alpha) are bounded. The spaces Ea are interpolation spaces between E-0 and E, depending on alpha = (alpha(1), alpha(2), . . . , alpha n) and l = (l(1), l(2), . . . , l(n)). The results obtained are applied to prove the separability of anisotropic differential operator equations with variable coefficients.
A RESEARCH ON MEASURING CONSUMER ETHNOCENTRISM OF YOUNG TURKISH CUSTOMERS PURCHASING BEHAVIORS
(Univ Belgrade, Technical Faculty At Bor, 2008) Candan, B.; Aydin, K.; Yamamoto, G. T.
After the fall of the Berlin Wall, important changes have occurred world wide. Not only the Berlin Wall, but also technological improvements such as the Internet affected businesses as befits humans. Globalization bias presents considerable challenges and opportunities for international marketers. The relaxation of trade policies has provided consumers with more foreign product choices than ever before (Wang & Chen, 2004). As a developing and a posseser of the young generation country, Turkey has also taken her share from this metamorphosis and winds of globalization. This has been accelerated by the imports of foreign products. There have been great changes in consumer behavior because of this acceleration. Some economical and political crisis has also brought reactions. Therefore, it is very important to study consumers' ethnocentric tendencies and factors which affect their buying preferences and buying behavior. This paper seeks to examine the concept of "consumer ethnocentrism'' (CE) and its impact on product evaluation and preferences among young Turkish consumers.
Adaptation, validity, and reliability of the metacognition questionnaire-30 for the Turkish population, and its relationship to anxiety and obsessive-compulsive symptoms
(Turkiye Sinir ve Ruh Sagligi dernegi, 2008) Tosun, Ahmet; Irak, Metehan
Objective: The present study aimed to evaluate the psychometric properties of the short form of the Metacognition Questionnaire (MCQ-30) in a population of Turkish university students. The metacognitions questionnaire (MCQ) measures individual differences in a selection of metacognitive beliefs, judgments, and monitoring tendencies considered important in the metacognitive model of psychological disorders. Method: The study included 850 university students from 15 Turkish universities. Mean age age of the participants was 21.22 years, 282 (33.17%) were female, and 558 (66.82%) were male. Results: Construct validity was evaluated by exploratory and confirmatory factor analysis (CIA). Exploratory factor analysis revealed that the Turkish version of MCQ-30 has 5 components, which is some factor structure as the original form. In addition, the fit indices of CIA suggested an acceptable fit to a 5-factor model consistent with the original MCQ-30. The Turkish MCQ-30 showed acceptable to good test-retest reliability, internal consistency, and convergent validity. Significant positive relationships between the subscales of MCQ-30 and measures of anxiety and obsessive-compulsive symptoms provided further support for the convergent validity of the Turkish version. Moreover significant negative correlations were observed between age and the MCQ-30 subscales, and the effect of gender was significant on some of the subscales. Conclusion: The psychometric properties of the Turkish version of MCQ-30 showed that the instrument is a valuable additional tool for the assessment of metacognition in Turkey.
Note on Faraday's law and Maxwell's equations
(Iop Publishing Ltd, 2008) Kholmetskii, Alexander L.; Missevitch, Oleg V.; Yarman, Tolga
We generalize the approach developed by us for the evaluation of the total time derivative of circular integral (Kholmetskii A L et al 2008 Eur. J. Phys. 29 L1-4) and derive an explicit expression for the total time derivative of the area integral for a differentiable vector field. On the basis of this expression, we prove for the first time that Faraday's law can be directly obtained from the Maxwell equations del x E = -delta B/delta t, del center dot B = 0 and the Lorentz force law.
