A new model for heating of Solar North Polar Coronal Hole

This paper presents a new model of North Polar Coronal Hole (NPCH) to study dissipation/propagation of MHD waves. We investigate the effects of the isotropic viscosity and heat conduction on the propagation characteristics of the MHD waves in NPCH. We first model NPCH by considering the differences in radial as well as in the direction perpendicular to the line of sight (\textit{los}) in temperature, particle number density and non-thermal velocities between plumes and interplume lanes for the specific case of \ion{O}{VI} ions. This model includes parallel and perpendicular (to the magnetic field) heat conduction and viscous dissipation. Next, we derive the dispersion relations for the MHD waves in the case of absence and presence of parallel heat conduction. In the case of absence of parallel heat conduction, we find that MHD wave dissipation strongly depends on the viscosity for modified acoustic and Alfven waves. The energy flux density of acoustic waves varies between $10^{4.7}$ and $10^7 \,erg\,cm^{-2}\,s^{-1}$ while the energy flux density of Alfven waves turned out to be between $10^6-10^{8.6} \,erg\,cm^{-2}\,s^{-1}$. But, solutions of the magnetoacustic waves show that the parallel heat conduction introduce anomalous dispersion to the NPCH plasma wherein the group velocity of waves exceeds the speed of light in vacuum. Our results suggests all these waves may provide significant source for the observed preferential accelerating and heating of \ion{O}{VI} ions, in turn coronal plasma heating and an extra accelerating agent for fast solar wind in NPCH.Comment: 17 pages, 11 figures, Submitted to MNRA

AN ANALYSIS OF TURKEY REGARDING THE DECENTRALIZATION AND LOCAL GOVERNMENT REFORM

In the post-80s, within the context of liberalization and globalization a reform on the local governments was called for all around the world. In line with this trend, reforms were put into practice in Turkey. However, these reforms were not systematically implemented up to 2000s. After the Justice and Development Party came to power, local governments were financially and administratively strengthened. Local governments have begun to come to the fore within the administrative structure in terms of authority, duties and responsibilities. In the last decade they have been the driving force of the economic production being in harmony with the market. Apart from this general picture of transformation, the government has carried out two important policies. The first one is the closure of minor local government units (municipalities and villages). The second policy is the enlargement of the borders of metropolitan and provincial municipalities. In many settlements, the process of enlargement has been implemented to include the first policy. At the end of the year 2012, a law which epitomized these decade-long reforms on local governments was passed and with this law the outline of this reform process was drawn and concretized. This paper aims at briefly explaining the mentioned reform process and evaluating it from different perspectives

On M-projectively flat LP-Sasakian manifolds

In the present paper, we study the nature of LP-Sasakian manifolds admitting the M-projective curvature tensor. It is examined whether this manifold satisfies the condition W(X, Y ).R = 0. Moreover, it is proved that, in the M-projectively flat LP-Sasakian manifolds, the conditions R(X, Y ).R = 0 and R(X, Y ).S = 0 are satisfied. In the last part of the paper, an M-projectively flat space-time is introduced, and some properties of this space are obtained.Вивчається природа многовидів Сасакяна, що допускають M-проективний тензор кривизни.

Evaluation of Student Surveys based on Lectures

AbstractThe most important component of innovation and accreditation in education and training is participation of the students who are the stakeholders in the process. This participation increases the options in education and training and directs the operation of the course. Participation of the students in the course and the quality of the course direction which is provided by a faculty member can be determined using course and student surveys. For this reason, student surveys should be done regularly and these surveys must have questions about the content of the course, the laboratory work and the function of the lecturer as well the knowledge, perception and values of the professional ethics gained by the student. But more important than this surveys are the objective responses of students. In this study, to understand the relationship between survey responses and success rate, surveys were carried out in different course groups between the years 2005-2012 in the Civil Engineering Department of the Yildiz Faculty of Civil Engineering at Yildiz Technical University. Finally, the objectivity of the students was determined by evaluating the survey responses from different perspectives

Use of Film Scripts and Their Translations in Teaching English as a Foreign Language

Although millions of EFL learners benefit from watching subtitled/captioned movies andTV shows in non-instructional settings, one almost untouched area is the development ofstrategies in benefiting from film scripts and their translated versions as well as audiolanguage-subtitle combinations. This paper reports research subsequent to theresearcher/teacher's guided work on the use of film scripts and their translated versions. Thestudents guided were required to notice and list chunks as well as technical and creative useof language in these scripts with their immediate contexts. This was carried out comparingthe original scripts and those translated in Turkish and do creative dialogue/anecdote writingfocusing on appropriacy and variety in language use. However some students' self-reportedlack of focus on the jargons and formal language. The research was conducted with 1-5Likert type questionnaires and closed-ended yes/no questions. The participants, the studentsof the research/teacher of the present paper, are the undergraduate students taking advancedlanguage skills course as part of the curriculum of their major, the English language andliterature. The results demonstrated that the film scripts can be used to convert the inputprovided by the film scripts to intake and uptake and provide good examples regarding theapplication of own language use in ELT

The examination of gathering points' capacity regarding mobility and accessibility: Case of Bayrakli district

The concept of accessibility that bases on continuing the flow of people, goods and services uninterruptedly is discussed as "maximum contact by minimum facility". This concept which is related with the distance has been evaluated various criteria such as physical, economic, perceptual, temporal, etc. Several assignations (optimum location, minimum distance, best distribution method, etc.) have revealed the importance of gathering points in terms of proceeding the disaster management properly. The origin point of linking "accessibility" and "transportation network" is the mobility which reveals as accessing people to adequate gathering points and services in the shortest time. These gathering points which are determined due to the specific criteria and also referred to the social infrastructure areas have a vital importance when any disaster or emergencies occur; so the site selection, availability and accessibility of these areas become extremely significant. The aim of this study is to examine the accessibility of gathering points in Bayrakli district located in Izmir city by taking minimum standards and also some recommendations into consideration. The spatial analyses based on current and potential gathering points are carried out via ArcMap software. The current and potential gathering points in Bayrakli district are examined in terms of accessibility their capacity for each neighbourhood due to their spatial distribution. According to the results, each gathering points in neighbourhoods cannot be accessible in the shortest duration by walking and also the current urban pattern affects the capacity parameter regarding the accessibility and mobility significantly. © Authors 2018.

The Impact of STEM Applications on Problem-Solving Skills of 4th-Grade Students

This study examined the impact of STEM applications realized with 4th-grade elementary school students on their problem-solving skills. The study was conducted within the convergent parallel design framework, a mixed research method. The research was carried out with 42 4th-grade primary school students, 21 in the experimental group and 21 in the control group, studying in a public school in Turkey. In the study, which lasted for ten weeks, STEM applications were carried out with the students in the experimental group. The control group applied the current science curriculum without performing STEM applications. The research data consists of the Developing Problem Solving Inventory for Children at the Level of Primary Education (PSIC) and the semi-structured interview conducted with the students in the experimental group. Quantitative data were analyzed using an independent sample t-test, while qualitative data were analyzed with content analysis. When the PSIC post-test scores of the 4th-grade primary school students in the experimental and control groups were examined, a statistically significant difference was found in favor of the experimental group. According to the qualitative data analysis of the study, it was determined that the students encountered various problems in the process and developed solutions for them. The students stated that using STEM activities in the classes is fun, so they learn more permanently and easily, and they want the classes to be delivered in this way from now on
