Grup folkloru bağlamında tahtakale esnafı ve geliştirdikleri dilsel kodlar
(Geleneksel Yayıncılık, 2012) Kekeç, N.
15. yüzyıldan bugüne uzanan çizgide kültür ve ticaret merkezi olarak anıla gelen Tahtakale, İstanbul’un en canlı ticaret merkezlerinden biridir. İstanbul’un fethinden sonra gayri Müslim esnafın ticari konumlarında bir değişiklik yapılmamış; bunun yanı sıra zaman içerisinde Müslüman esnafın da ticarette bulunması semte yeni ve kendine has bir kimlik kazandırmıştır. İstanbul’da kahvehanelerin ilk olarak Tahtakale’de açılması, semte sosyal bir mekan olma özelliğini de katar. Farklı etnik gruplar Tahtakale’de bir araya gelip sosyal paylaşımda bulunarak “dil”i çokkültürlülük bağlamnda kullanma olanağına sahip olurlar. Günümüze uzanan bu süreçte Tahtakale’nin bu çok dilli, çok kültürlü yapısı semt esnafı arasındaki iletişimde de kendini gösterir. Bu kozmopolit yapıda kültürlenme sürecini gerçekleştiren semt, dilsel gelişimini de mevcut çok dilli yapı üzerinden geliştirir. Alan Dundes’in grup tanımından yola çıkarak Tahtakale esnafını “dil” faktörünü paylaşan bir topluluk olarak ele almak mümkün görünmektedir. Esnaf, kendi dilsel kodlarını üreterek ticaret alışkanlıklarına ilişkin özgün bir dil; âdeta bir “Tahtakalece” yaratmıştır. Tahtakale’nin kültürel zenginliğinin, semtin kendine has dilinin çeşitli süreçlerden geçerek bu güne kadar evrilmesine neden olduğu görülmektedir. Temelde usta-çırak ilişkisindeki iletişim alışkanlıklarına dayanarak hazırlanan bu makalede, semtin dilsel kodlarının bazı örneklerine yer verildikten sonra; bu kodlar, bağlamlarında yarattığı sosyo-kültürel etki dolayımıyla ele alınmaktadır.

Influence of differentiated roles on group forecasting accuracy
(Elsevier, 2011-03) Önkal D.; Lawrence, M.; Sayım, K. Z.
While behavioral research on forecasting has mostly examined the individual forecaster, organizationally-based forecasting processes typically tend to rely on groups with members from different functional areas for arriving at ‘consensus’ forecasts. The forecasting performance could also vary depending on the particular group structuring utilized in reaching a final prediction. The current study compares the forecasting performance of modified consensus groups with that of staticized groups using formal role-playing. It is found that, when undistorted model forecasts are given, group forecasts (whether they are arrived at through averaging or by a detailed discussion of the forecasts) contribute positively to the forecasting accuracy. However, providing distorted initial forecasts affects the final accuracy with varying degrees of improvement over the initial forecasts. The results show a strong tendency to favor optimistic forecasts for both the staticized and modified consensus group forecasts. Overall, the role modifications are found to be successful in eliciting a differential adjustment behavior, effectively mimicking the disparities between different organizational roles. Current research suggests that group discussions may be an efficient method of displaying and resolving differential motivational contingencies, potentially leading to group forecasts that perform quite well.

Remarks on conversion of sentences from active voice to passive voice: Algebraic analysis of mathematical model approach
(MTJPAM Turkey, 2023-02-21) Hazar, Melis Öyku; Şimşek, Yılmaz
The aim of this paper is to investigate and survey some fundamental functions, which are related to homomorphisms, properties that can be used to change active voice into passive voice. These functions are explained with the relevant examples. Some observations are also made about how the inverses of these functions can behave. Finally, we raise a number of new and distinct problems that allow for further research and analysis to fully comprehend grammatical structures. © 2023, MTJPAM Turkey. All rights reserved.

Scenarios as channels of forecast advice
(Elsevier, 2013-05) Önkal, D.; Sayım, K. Z.; Gönül, M. S.
Today's business environment provides tougher competition than ever before, stressing the important role played by information and forecasts in decision-making. The scenario method has been popular for focused organizational learning, decision making and strategic thinking in business contexts, and yet, its use in communicating forecast information and advice has received little research attention. This is surprising since scenarios may provide valuable tools for communication between forecast providers and users in organizations, offering efficient platforms for information exchange via structured storylines of plausible futures. In this paper, we aim to explore the effectiveness of using scenarios as channels of forecast advice. An experimental study is designed to investigate the effects of providing scenarios as forecast advice on individual and group-based judgmental predictions. Participants are given time series information and model forecasts, along with (i) best-case, (ii) worst-case, (iii) both, or (iv) no scenarios. Different forecasting formats are used (i.e., point forecast, best-case forecast, worst-case forecast, and surprise probability), and both individual predictions and consensus forecasts are requested. Forecasts made with and without scenarios are compared for each of these formats to explore the potential effects of providing scenarios as forecast advice. In addition, group effects are investigated via comparisons of composite versus consensus predictions. The paper concludes with a discussion of results and implications for future research on scenario use in forecasting.
