Yayın A new late holocene eolianite record from Altinkum Beach, North Cyprus(Scientific technical research council Turkey-Tubitak, 2012-06) Erginal, Ahmet Evren; Güneç Kıyak, Nafiye; Ertek, Topçu AhmetIn this study, we investigated the main depositional characteristics and obtained Optically Stimulated Luminescence (OSL) ages of coastal eolianite on the north coast of Cyprus, where this occurrence had not previously been recorded. Based on EDX/SEM and XRD data and field observations, the studied eolianite that crops out between elevations of 1 m and 14 m a.s.l. is made up predominantly of quartz grains, most of which consist of medium- to fine-grained sand. The rock comprises aragonite, calcite and quartz with lesser amounts of bornite and hematite as accessory minerals. OSL ages indicated that the initial deposition of eolianite sands took place at 1.51 +/- 0.21 ka years ago.Yayın Optically stimulated luminescence to date coastel dunes and a possible tsunami layer on the Kavak Delta (Saros Gulf, NW Turkey)(Scientific Technical Research Council Turkey-Tubitak, 2009-01-21) Erginal, Ahmet Evren; Güneç Kıyak, Nafiye; Özcan, HasanOptically stimulated luminescence (OSL) dating was used to determine the timing of initial dune formation and reconstruct the evolution of coastal dunes that developed on the Kavak Delta, Saros Gulf, Turkey. Along a 500-mlong representative transect, dune sands were extracted from foredune, semistable (grey) dune, stable (dark) dune and dune-swamp boundary defined by a scarp 50?75 cm high. The data obtained showed that dune drift initiated 670 years ago. A pumice layer 15?20-cm-thick interbedded with marine clay and sand showed an OSL age of 340 years coinciding with underlying dune sand. XRF analysis showed that pumices were of similar composition to those erupted by plinian activity of Thera (Santorini) in 1628 BC. On the basis of OSL ages, these deposits, which are widely distributed on the western Anatolian coasts of Turkey, might have presumably transported landward along tide channels on the delta during a tsunami event that occurred in 1672 near Bozcaada and Kos islands according to tsunami history of the Aegean Sea.Yayın Parametrik ve parametrik olmayan verimlilik değerlendirmesi ve karşılaştırılması: Türkiye elektrik santralleri örneği(Bursa Uludağ Üniversitesi, 2017) Sarıca, KemalÇalışma boyunca Türkiye’deki çeşitli enerji santrallerinin operasyonel ve uzun vadeli yatırım performansları Stokastik Sınır Analiz (SSA) ve Veri Zarflama Analizi (VZA) kullanılarak karşılaştırıldı. Veri kümesi, özel ve kamu mülkiyetindeki 65 termal, hidroelektrik ve rüzgâr enerji santrallerinden oluşturuldu. Operasyonel ve yatırım performansını yansıtan verimlilik endeksleri ortaya konup incelendi. Analizde ölçek, sabit ve değişken, güvence bölgesi, gevşek tabanlı ölçüm, sistem karşılaştırma ve bilateral tip DEA modelleri ile Cobb-Douglas ve Translog üretim fonksiyonlarını kullanan stokastik sınır analizi kullanıldı. Ölçek getirisinin analizine yönelik VZA ve SSA modellerinin ortaya koyduğu tüm indisler kullanılarak değerlendirmeler yapıldı. Kamu-özel, termal-yenilenebilir karşılaştırmalarının yanı sıra doğal gaz-kömür-petrol santralleri verimlilik performans değerlerine göre karşılaştırıldı. VZA ve SSA metotlarından elde edilen sonuçlar karşılaştırıldı. İlginç verimlilik endeksi ve çeşitli giriş/çıkış faktörleri arasında ilişkiler ortaya kondu ve değerlendirildi. Doğal gazla çalışan elektrik santralleri, yatırım verimliliği açısından kömürle çalışan santrallerden daha iyi performans gösterse de, değişken getiri oranlarına göre operasyonel performansı için tersi geçerlidir.Yayın The effects of vocabulary strategy training on vocabulary learning and autonomy: a case study of Turkish EFL students(Akdeniz Üniversitesi Edebiyat Fakültesi, 2011) Nalkesen, Yeşim; Özek, YeşimUse of language learning strategies can play a very important role on the way to gain success and learner autonomy in language learning. They can be more powerful learning tools provided that they are chosen properly according to the situations language learners will be faced with. For learners’ to receive strategy training is very important in helping them with tackling the language situations they will encounter. Use of learning strategies serves as an effective way for learners to overcome such difficulties. According to Willliams and Burden (1997), use of appropriate language learning strategies has a vital contribution to make to language learning success, which underlines the significance of the incorporation of strategy training in teaching a foreign language. The present study had two main purposes. Firstly, it aimed to investigate the effects of vocabulary strategy training on vocabulary learning and, secondly, it aimed to investigate the effects of vocabulary strategy training on learner autonomy at intermediate level in the preparatory classes of a foundation university.
