No full textBu çalışmanın amacı 8. sınıf seviyesinde yapılan Uluslararası Matematik ve Fen Eğilimleri Araştırmasında (Trends in International Mathematics and Science Study [TIMSS]) sayılar alt öğrenme alanına ait konular temel alınarak Singapur’u, ABD’yi ve Türkiye’yi temsil eden 5.- 8. sınıf ders ve çalışma kitaplarındaki soruların TIMSS bilişsel düzeylerine göre karşılaştırılmasıdır. Araştırmanın verileri doküman analizi yapılarak toplanmış ve 8. sınıf TIMSS bilişsel düzeylerine göre kodlanmıştır. Bu araştırmada nitel yöntemlerden biri olan betimsel analiz yöntemi kullanılmıştır. Elde edilen sonuçlara göre, Singapur’u, ABD’yi ve Türkiye’yi temsil eden 5. sınıf matematik kitaplarında sayılar alt öğrenme alanında bilgi düzeyinde yer alan soruların yüzdelerinin sırasıyla %85 (333), %85 (4855), %67 (780) ve uygulama düzeyindekilerin %12 (49), %13 (756), %29 (340) olduğu görülmektedir. Akıl yürütme düzeyindeki dağılımın ise Singapur için %3 (11), ABD için %1 (72) ve Türkiye için %4 (41) olduğu saptanmıştır. Benzer bir araştırma 6. sınıf matematik kitaplarındaki sorular çerçevesinde yapıldığında bilgi düzeyindeki soruların Singapur, ABD ve Türkiye kitaplarında %55 (177), %67 (1547), %69 (90); uygulama düzeyindeki soruların ise %42 (135), %27 (628), %31 (40) oranlarında yer aldığı görülmektedir. Akıl yürütme düzeyindeki soruların Singapur’u temsil eden kitapta %3 (8) oranla, ABD’yi temsil eden kitapta %5 (120) oranla yer almakta olduğu fakat Türkiye’yi temsil eden kitapta akıl yürütme düzeyinde hiç soru bulunmadığı görülmektedir. 7. sınıf matematik kitaplarındaki sorular TIMSS bilişsel istem düzeylerine göre incelendiğinde, bilgi düzeyindeki soruların Singapur kitabında %69 (512), ABD kitabında %60 (1353), Türkiye kitabında %60 (222); uygulama düzeyindeki soruların ise sırasıyla %24 (177), %37 (845), %38 (142) olduğu saptanmıştır. 7. sınıfta akıl yürütme düzeyindeki soruların Singapur’da %7 (48), ABD’de %2 (47) ve Türkiye’de %1 (5) oranında olduğu görülmüştür. Bu ülkeleri temsil eden 8. sınıf kitaplarındaki sorular bilişsel istem düzeylerine göre kategorize edildiğinde Singapur, ABD ve Türkiye’de sırasıyla bilgi düzeyindeki soruların %48 (75), %69 (316), %68 (149); uygulama düzeyindeki soruların %32 (50), %25 (115), %30 (65) oranında olduğu bulunmuştur. Bu sınıf seviyesindeki akıl yürütme düzeyindeki sorulara bakıldığında ise Singapur kitaplarında %20 (31), ABD kitaplarında %6 (28), Türkiye kitaplarında %3 (6) oranında bu tür soru olduğu saptanmıştır. Genel sonucu görebilmek için 5.-8. sınıf kitaplarında sayılar alt öğrenme alanındaki soruların bilişsel istem düzeylerine göre toplamının dağılımı belirlenmiştir. Buna göre Singapur, ABD ve Türkiye için bilgi düzeyindeki soruların yüzde dağılımı sırasıyla %68 (1097), %75 (8071), %66 (1241); uygulama düzeyindeki soruların yüzde dağılımı ise %26 (411), %22 (2344), %31 (587) şeklindedir. Akıl yürütme düzeyinde yüzde olarak en fazla soru %6 (98) oranıyla Singapur kitaplarında yer almaktadır. Singapur’un ardından gelen ABD (267) ve Türkiye (52) %3 ile eşit oranlara sahiptir. Fakat ABD ile Türkiye’nin akıl yürütme yüzdeleri eşit olsa da soru sayısına bakıldığında ABD kitaplarında Türkiye’nin 5 katından fazla akıl yürütme sorusu olduğu görülmektedir. Türk öğrencilerin TIMSS matematik alanında daha başarılı olabilmeleri için ders kitaplarındaki soru sayısının arttırılması ve öğrencilerin bilişsel istem düzeyi daha yüksek sorularla karşılaşmasına olanak sağlanması tavsiye edilmektedir.
The aim of this study is to compare the cognitive demand levels of questions, in the content domain of numbers in the 5th through 8th grade textbooks/workbooks used in Singapore, the US and Turkey. The data for this study was gathered using document analysis. This data was then coded according to the cognitive demand levels used in the Trends in International Mathematics and Science Study (TIMSS). This is a qualitative study that utilizes descriptive analysis. Based on the results obtained, the percentage of questions according to cognitive demand level of knowing was 85% (333), 85% (4855), 67% (780) respectively in the Singaporean, the US, and Turkish 5th grade textbooks. That of applying was 12% (49), 13% (756), 29% (340) and that of reasoning was 3% (11), 1% (72), 4% (41) in Singapore, the US and Turkey respectively. Similar results were found for 6th grade textbooks, where Singapore, the US and Turkey had 55% (177), 67% (1547), 69% (90) of knowledge and 42% (135), 27% (628), 31% (40) of application questions respectively. Reasoning questions formed 3% (8) of the number related questions in Singapore, and 5% (120) of them in the US, but there were no questions in this category in Turkey’s 6th grade mathematics textbooks. When the cognitive demand levels of questions in the 7th grade mathematics textbooks representing Singapore, the US, and Turkey were analyzed, the distribution of knowledge questions was found to be 69% (512), 60% (1353), 60% (222); that of applying was 24% (177), 37% (845), 38% (142), and that of reasoning was 7% (48), 2% (47), 1% (5) respectfully. When the cognitive demand levels of questions were analyzed in these countries’ 8th grade textbooks, questions requiring knowing was found to be 48% (75), 69% (316), 68% (149), of applying was found to be 32% (50), 25% (115), 30% (65) in Singapore, the US and Turkey respectively. When reasoning questions were analyzed at this grade level, the percentages were determined to be 20% (31) for Singaporean, 6% (28) for the US, and 3% (6) for Turkish textbooks. In order to obtain the final result of this study the total number of questions in each of the three cognitive demand levels were calculated for 5th through 8th grade textbooks according to the specific country. According to these findings, in Singaporean, the US and the Turkish textbooks, the distribution of questions requiring knowing were 68% (1097), 75% (8071), 66% (1241) and those requiring applying were 26% (411), 22% (2344), 31% (587) respectively. The highest percentage (6%, number 98) of reasoning questions were found in the Singaporean textbooks. This was followed by the US and Turkish textbooks that both contained 3% reasoning questions; though the US (267) contained far more reasoning questions than that of Turkey (52). Percentagewise the US and Turkish textbooks may look the same but the US textbooks had more than five times the number of reasoning questions Turkish textbooks had. In order to increase Turkish students’ level of success in TIMSS, it is recommended that both the number and cognitive demand levels of questions in the Turkish mathematics textbooks are increased

Especially, the vessels named marina enable people to satisfy their curiosity and see new places. In relation to all of these, in view of the marina, emerging gradually and one of the attractive tourism activities in the touristic arena of world, there are significant improvements in our country. As a matter offact, the number of marina carrying great importance for the marina tourism, is increasing more and more with the help of private initiatives, our competitive chance in this field is getting higher and higher. In this sense, our research topic, Didim Marina, draws attention as one of the most favourite investments in the field of marina of our country. Since May 2009, as well as one of the most capacity ports of our country, Didim Marina starting to take marina is quite an important investment in view of the improvements in marina tourism in Didim and stressing the identity "marina city " of Didim. The marina, having high quality and capacity equal to Bodrum, Ku adas and Marmaris marinas in our country, is also of vital importance with a view to varying the tourism activities of Didim and its neighbourhood. If the marina, quite a significant investment in also making up the alternatives in the field of tourism transportation in Didim, is supported with cruise marina to be provided and if its advertisement is made well and if its connection with Mylasa-Bodrum Airport is improved, has the potential to convert Didim into significant marina tourism
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Stroke/Bore Ratio on SI Engine Performance
No full textIn this study, the effects of the stroke/bore (S/B) ratio on the performance parameters of an engine having dual-spark ignition (DSI) were investigated theoretically by using a quasi-dimensional thermodynamic cycle model. A range of S/B ratios for various spark-plug locations were examined in the scope of the study. The engine performance parameters, i.e., engine power, indicated mean effective pressure, specific fuel consumption, and thermal efficiency, were computed for various conditions. The obtained results for DSI operation have been compared to those of a single-spark-ignition (SSI) condition. Such comparisons showed that increases in the S/B ratio cause improvements in engine performance parameters. The dual-plug operation also improves the overall engine performance at different percentages for the selected S/B ratios
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The Effect of Compensation Studies on Disadvantaged Children s Bully Behaviours
No full textChildren who are economically, educationally, linguistically or socially disadvantaged called “disadvantaged children”. Those children are at risk and they must be supported because of their negative life conditions. Compensation studies must be implemented to those children. The “Bir Umut Ol Benim İçin” (Be My Hope) project is such a compensation study which is held by Uludag University Faculty of Education and Bursa Police Department Children Branch Office. The aim of this study is to determine the impact of this project on disadvantaged children’s bullying behaviours. In line with this objective Colorado School Climate Survey, which was developed by Garrity et al., (2000) was used. The questionnaire was designed to measure several aspects of bullying. The analyses of the study showed that the project “Bir Umut Ol Benim İçin” has not caused a positive effect on the bully behaviours. While it was hoped that this project would cause a decrease in bully behaviours of disadvantaged children because it is a compensation study, it is seen that such as studies/projects must be supported with bully proofing and with conflict resolution programs
New Product Branding in Food Sector: Comparative Analysis of Branding of Different Products
No full textGünümüz rekabet ortamında işletmelerin pazar paylarını arttırabilmeleri, hedeflerine ulaşabilmeleri, karlılık ve rekabette üstünlük sağlayabilmeleri ve farklılaşabilmeleri için tüketicilerin ihtiyaçlarına cevap verecek ve tüketiciye maksimum fayda sağlayabilecek ürünleri pazara sunmaları gerekmektedir. Yeni fikir ve yeni ürün üretmek farklılaşma için atılacak önemli adımdır. Yeni bir ürünün başarılı olabilmesi için ürünün tüketiciler için fayda sağlamasının yanında, doğru pazarlama stratejilerinin belirlenmesi şarttır. Farklılaşmayı sağlayan etkenlerden biri de markalamadır. Marka, ürünün taşıdığı somut anlamın ötesinde ona, soyut bir anlam da katmaktadır. Yani, ürün fayda sunarken, marka onun ötesinde imaj, saygınlık gibi soyut anlamlar da ifade etmekte ve tüketicide güven yaratmaktadır. Bu tez çalışmasının konusunu pazarlamada yeni ürün, yeni ürün geliştirme süreci ve yeni ürünlerin markalanması oluşturmaktadır. Çalışmanın ilk üç bölümünde konular kavramsal olarak anlatılmış; dördüncü bölümde gıda sektöründe öncü bir şirket olan Ülker'in çikolata ve mutfak gruplarından iki ürününde bu konular örnek olay yöntemiyle karşılaştırılmış ve analiz edilmiştir. Beşinci bölümde ise değerlendirme yapılarak sonuç ve öneriler sunulmuştur.In today's competitive environment, the companies should develop and offer the market products which respond to the needs of the consumers and provide them the maximum value in order to increase their market share, achieve their goals, improve their profitability and differentiate themselves among their competitors. Creating new ideas and products is important for differentiation. In order for a product to be successful, it is inevitable to determine the right marketing strategies besides the fact that the product should provide value to the customers. One of the factors which provides differentiation is branding. Brand contribute also an abstract meaning to the product beyond its concrete meaning. Thus, while the product provides value, brand carries also abstract meanings such as image and prestige and creates trust in the consumer. The subject matter of this thesis is composed of new product, new product development process and branding of new products. In the first three parts, the subjects are theoretically explained. In the fourth part, new product development process and branding of two new products belonging to two different food product groups-chocolate and kitchen group- are compared and analyzed at a leading company at food sector, Ülker. In the fifth part, the assessment, conclusions and recommendations are presented
