Ground level ozone exposure and distribution over the historical Peninsula of Istanbul

In this study, passive samplers were used to measure ozone exposure distribution maps over the historical peninsula of Istanbul, Turkey. The study area is partially important due to the presence of cultural and historical buildings and structures distributed all over the peninsula. Unesco's World Heritage list covers four zones located in this historical peninsula in Istanbul. It is necessary to evaluate the pollution distribution in high resolution to construct effective risk management strategies. For this purpose, 50 sampling stations were installed within the study area. Three sampling campaigns within different seasons (summer, winter and fall) showing different ozone distribution characteristics were carried out. Seasonal measurements of ozone exposure values were used to obtain a yearly exposure level, which is an important part of risk characterization. Seasonal ozone exposure maps over the historical peninsula were obtained using Geographical Information Systems (GIS) based interpolation models with high resolution. Risk maps including five regions, based on ozone exposure levels were created. Structures and historical regions located within these risk zones were identified. Based on the defined exposure regions, we found that the Archaeological Park, one of the items on UNESCO's list, is located within the most risky region.     

Technology utilisation in elementary schools in Turkey’s capital: a case study

A case study was conducted to explore teachers’ current technology use in elementary schools in Ankara, the capital of Turkey. The data were collected through a survey, and participants included 1030 classroom teachers across eight districts. The present study results revealed that significant challenges remain with regard to technology use in the classroom, even in the capital of Turkey, where teachers have advantages in terms of technology access and use compared to rural areas. The participant teachers used technologies most frequently for lesson preparation activities, rather than for delivering instruction. Although the teachers felt that school principals and colleagues were usually supportive of technology use in lessons, they complained about insufficient professional development activities and incentives. Representing a snapshot of teachers’ technology use in elementary school settings, this study sheds light on essential factors that should be considered in any technology integration process in schools. The study findings offer valuable insight for policy-makers and school leaders on how to support the technology integration process and allocate money for technology initiatives.     

The effect of the attachment styles and self-efficacy of adolescents preparing for university entrance tests in Turkey on predicting test anxiety

The purpose of this study was to determine the effect of attachment styles and self-efficacy of adolescents preparing for university entrance exams in Turkey on predicting test anxieties. The study group consisted of 884 final-year high school students (423 female and 461 male) attending different types of high school, preparing for university entrance exams and aged between 16 and 19. Participants were administered the Relationship Scales Questionnaire, the Self-Efficacy Scale and the Test Anxiety Inventory in groups in a classroom environment for data collection. Results showed that test anxiety is significantly correlated with self-efficacy and attachment styles. Dismissing, fearful and secure attachment styles and self-efficacy have the potential to predict test anxiety. In addition, the variable of gender was determined as influencing factors in test anxiety.     

Teachers’ Facebook use: their use habits,intensity, self-disclosure,privacy settings,and activities on Facebook

This study investigated K12 teachers’ Facebook usage habits, intensity, self-disclosure, privacy settings and activities. A multi-method design was employed by collecting quantitative data from 616 teachers with a Facebook account using an online questionnaire and qualitative data from 32 teachers using online open-ended questions. The results of the study showed that Facebook seems to be part of teachers’ daily routines. Moreover, they revealed that teachers were less likely to share sensitive and potentially stigmatising personal information on Facebook. Teachers were also found to set most of their Facebook privacy settings as “Friends” by taking intimacy, unwanted contacts and potential threats into consideration. Furthermore, the findings indicated that teachers felt themselves less comfortable when parents and students viewed their Facebook profiles. In addition to social engagement, teachers pointed out several ways in which Facebook was used to support educational and professional development practices. Implications, limitations and directions to further studies are discussed.     

Mapping the corrosion impact of air pollution on the historical peninsula of Istanbul

This paper presents the most comprehensive study conducted so far for evaluating the corrosion levels related to air quality and the seasonal pollutant (NO₂, SO₂, and O₃) exposure levels over 50 monitoring stations distributed on the historical peninsula of Istanbul. Istanbul has been one of the most important as well as most populated major cities in the world during all the ages. Today, owing to its historical and cultural structures, the historical peninsula of Istanbul has become an attraction point of tourism and is one of the most unique and ancient urban settlement areas in the world. However, the cultural heritage stocks in the peninsula are under the risk of corrosion and critical air pollution level exposure caused by chemical reactions under the multi-pollutant situation of the air pollutants, principally SO₂, NO₂, and O₃, as well as meteorological factors, e.g. humidity and temperature. In the present study, seasonal exposure of NO₂, SO₂, and O₃ pollutants were monitored using passive samplers, and corrosion attack values were calculated using dose-response functions. The geostatistical analyst tool of ArcGIS^® 9.1 was then used for generating GIS-based surface pollution and corrosion distribution maps. Subsequently, two hotspots were clearly identified, the tip of the peninsula and the area around the Ataturk Bridge, which fall under serious corrosion risks for copper, cast bronze, and carbon steel materials. However, no significant risk was identified for cultural heritage materials made of limestone in the peninsula.     

Movies in Public Libraries: A Checklist Comparison with Internet Movie Database Recommendations

This research compares the fifty top-rated movies for 2000–2009 recommended by the Internet Movie Database (IMDb) with the holdings of ten medium-sized public libraries. The study shows that there was no relation between a movie's rank in the IMDb listing and the number of copies held. Relationships appeared between number of library holdings and country of production (U.S. productions favored), genre (family, sci-fi, animation, adventure favored), and Motion Picture Association of America (MPAA) rating (G, PG, PG-13 preferred). Library holdings seem to reflect preferences of IMDb raters aged 30 and older, not popular movie tastes.     

Architecture of a grid-enabled Web search engine

Search Engine for South-East Europe (SE4SEE) is a socio-cultural search engine running on the grid infrastructure. It offers a personalized, on-demand, country-specific, category-based Web search facility. The main goal of SE4SEE is to attack the page freshness problem by performing the search on the original pages residing on the Web, rather than on the previously fetched copies as done in the traditional search engines. SE4SEE also aims to obtain high download rates in Web crawling by making use of the geographically distributed nature of the grid. In this work, we present the architectural design issues and implementation details of this search engine. We conduct various experiments to illustrate performance results obtained on a grid infrastructure and justify the use of the search strategy employed in SE4SEE.     

Assessing in-service teachers' instructional beliefs about student-centered education: A Turkish perspective

The main purpose of this research is to examine in-service teachers' instructional beliefs about student-centered education. The inventory was designed to measure teachers' student-centered educational beliefs based on four components of the educational curriculum comprising of educational objectives, content, teaching strategies and instructional assessment. Data for the study were collected from 307 in-service teachers working at K-8 schools. A quantitative research analysis showed that in-service teachers held positive beliefs about student-centered education. In addition, the characteristics of teachers such as school level, teaching experience, teaching subject and educational background had statistically significant effects on their beliefs about student-centered education.
