A Mixed Integer Programming Model for Multi-Period Dyeing and Batching Problem in a Yarn Plant
(Computers and Industrial Engineering, 2014) Ozturk, Cemalettin; Örnek, Mustafa Arslan
In a so-called multi-period yarn dyeing and batching problem, we try to determine the optimal batching of customer orders to be dyed in dye machines in each shift to minimize total lateness and earliness costs. In addition to weight, production quantity and volume capacity of the machines, there is a set of technical dyeing interaction constraints such as flotte, colour types, colour percentages and chemical recipe of customer orders when yarns are immersed in a large vat of coloured water known as the dye-liquor that includes dyestuffs, plus a range of chemicals to assist the dyeing process in the same shift. Furthermore, because of multi-period multi-shift nature of the problem, there is a setup carryover restriction which enforces that from shift to shift the colours must be processed in the increasing degree of darkness, i.e., in technical terms, the colour percentage of the batch increases. To the best of our knowledge, there is no study in the literature to solve this combinatorial optimization problem. Hence, in this paper, we first develop a novel mixed integer programming (MIP) formulation and then, we present a case study in a worldwide known yarn manufacturing company.

Supporting the Writing Up of Teacher Research: Peer and Mentor Roles
(Oxford Univ Press, 2016) Dikilitas, Kenan; Mumford, Simon E.
This study focuses specifically on the writing up process of relatively inexperienced teacher researchers. The data consist of interviews with 11 teacher researchers at a private university in Turkey. There was evidence that mentor-supported collaboration created a socio-constructivist learning environment, leading to the development of academic writing skills. This was achieved by research partners sharing responsibility and negotiating the writing process and content. The data suggest that this process led to the teacher researchers experiencing longer term learning and greater autonomy as writers, although not all benefitted from collaboration, possibly because of conflict due to perceived differences in commitment. The study's implications highlight the importance of participant commitment, and, in particular, a supportive institutional environment. In the current study, the mentor played a key role in supporting the intrinsic motivation of the teacher researchers, but also in providing the essential instrumental motivations of conference presentation and publication opportunities.

Protest Music, Populism, Politics and Authenticity the Limits and Potential of Popular Music's Articulation of Subversive Politics
(John Benjamins Publishing Co, 2016) Way, Lyndon C. S.
Political discourses are found not only in speeches and newspapers, but also in cultural artefacts such as architecture, art and music. Turkey's June 2013 protests saw an explosion of music videos distributed on the internet. This paper uses these videos as a case study to examine the limits and potential of popular music's articulation of popular and populist politics. Though both terms encompass what is widely favoured, populism includes discourses which construct the people pitted against an elite. Past research has shown how popular music can articulate subversive politics, though these do not detail what that subversion means and how it is articulated. This paper uses specific examples to demonstrate how musical sounds, lyrics and images articulate populist and popular politics. From a corpus of over 100 videos, a typical example is analysed employing social semiotics. It is found that popular music has the potential to contribute to the public sphere, though its limits are also exposed.
