Why Do Students Consider Integrated Skills Lesson as a Grammar and Vocabulary Lesson

Abstract: This chapter focuses on student conceptions of a lesson in an Intensive English Programme (IEP) at a Turkish university. We realized that our students assume that the Integrated Skills (IS) strand is a grammar and vocabulary lesson, without noticing that it is a lesson where all skills are practised in an integrated way. In order to understand our puzzle ‘Why do the students consider Integrated Skills lessons as a grammar and vocabulary lesson?’, a small-scale phenomenological study was conducted with four teachers from the same institution through the use of normal pedagogic activities. We adopted an Exploratory Practice approach to gather data. The data suggest that students’ previous learning habits, difficulty in synthesizing different skills, their goals, and motivation affected their perceptions of the IS lessons. We conclude that all these factors are so interwoven that they affect learning English as a foreign language in this context.

Osmanlı Devleti Döneminde Reklamcılık Anlayışı ve 1908-1909 Tanin Gazetesi Örneği

Abstract: Gunumuz kosullarinin vazgecilmez unsuru haline gelen reklam, firmalarin siklikla kullandigi bir mal ve hizmet araci haline gelmistir. Teknolojinin de gelismesiyle birlikte mallarini pazarlayan firmalarin sayisi her gecen gun artmaktadir. Reklamin bu denli onemli bir sektor haline gelmesi, bu sektorun; gunumuz iletisim dunyasinda, ayni anda birden cok insanla iletisime gecebilme imkâni sunmustur. Bunun icindir ki pazarlama iletisim araclari arasinda reklam konusu ozel bir yere sahiptir. Ele alinan konumuzca da incelenen Tanin Gazetesi ornegi, Osmanli Devleti’nin son donemlerinde cikarilmaya baslanan bir yayindir. Osmanli Devleti’nin son donemi ve cumhuriyetin kurulus yillarina rastlayan Tanin Gazetesi, yayinlarinda verilen reklamlardan ziyade siyasi bir yayin organi olarak da on plana cikmaktadir. Konumuz geregi 1908-1909 yillarinda yayinlanmis Tanin Gazetesi’nin sayilari incelenmistir. Ele alinan yillardaki sayilarina bakilan Tanin Gazetesi icerik bakimindan bircok reklama ve markaya yer vermistir. Yayin hayati boyunca cesitli engellerle karsilasan gazete, Ittihat ve Terakki Cemiyeti mensuplari tarafindan kurulmus olmasi sebebiyle de dikkat cekmektedir

Competition and Innovation in Product Quality: Theory and Evidence from Turkey

Abstract: This paper examines how degree of competition affects incentives to innovate in product quality in a symmetric Cournot oligopolistic model. We model product quality in a quality-ladder framework, and find an inverted-U shaped relationship between the number of firms in an industry and R&D efforts in innovation. We test this theoretical prediction using Turkish firm-level data from the Business Environment and Enterprise Performance Survey (BEEPS) and find strong support for it.

s, S Inventory Control Optimization Under Inventory Sharing Policy for Omni-Channel Network

Abstract: Rapidly developing technology and multi-channel integrations in marketing have led to the emergence of omnichannel retailing. In omnichannel, consumers can take advantage of all shopping channels interactively. It overcomes the drawbacks of traditional supply chain applications, but uncertain stock demands cause serious difficulties and costs. In this work, an inventory sharing policy study presented for an omnichannel network in order to reduce the risks caused by stock and demand uncertainty. In literature, this policy also referred to as lateral transshipment. Recently, due to the increase in e-commerce, it has become significant to respond to customer demands shortly for customer satisfaction. Inventory sharing allows the exchange of items between the same echelon of the supply chain network enabling high service levels with low costs. Since, in an omnichannel network, physical transshipment may not take place due to the electronic order case, we prefer to state this policy as inventory sharing instead of lateral transshipment. We develop simulation models for three different omnichannel scenarios and optimize the total network cost by considering those three sharing policies. We compare each scenario’s optimal cost result. For the modeling and optimization purpose, we use the ARENA 16.0 commercial software and OptQuest to optimize the (s, S) inventory levels.

An Experimental Design Study to Identify Significant Factors Affecting Tier-to-Tier SBS/RS Performance

Abstract: The aim of this paper is to study a simulation-based experimental design to identify significant factors affecting the performance of the tier-to-tier shuttle based storage and retrieval system (SBS/RS). SBS/RS design is an automated warehousing technology mostly utilized for the storage of mini-loads. SBS/RS has emerged as a response to the recent order profile with low volume and wide variety and quick response. Although the traditional design of SBS/RS is comprised of multi-shuttles each dedicated in each tier of an aisle, there can be different designs in which shuttles can travel between tiers. We call this design as tier-to-tier SBS/RS where shuttles can travel between tiers by using a separate lifting mechanism located at an endpoint of each aisle. Note that in this new design, since shuttles are allowed to travel between tiers, there may be less number of shuttles running in the system. Hence, the shuttle’s average utilization value might be larger compared to that traditional one where each tier has a dedicated shuttle. In this work, we study an experimental design to investigate which factors are statistically significant on a critical performance metric (i.e., average cycle time per transaction) in the studied tier-to-tier SBS/RS. First, we simulate the system by using the ARENA 16.0 commercial software and then implement a full factorial analysis. The results are analyzed in MINITAB 17.0 software.
