Change is continuous and leaves many digital traces in contemporary organizations, while research on change usually lacks such continuity. The purpose of this paper is to test and explore the claim that change can be monitored through employee discourse. In doing so, the authors introduce basic text mining methods to detect prevailing keywords and their changes over time. Such monitoring of content and its change promises a continuous feedback and improvement for change management efforts.

The authors use a mixed research design, combining an ethnographic approach with digital methods. The quantitative element of the method involves applying text mining techniques to a document corpus that is representative of people in organizations, and is originally collected as part of a relatively common performance management system. The findings about discursive categories and their change patterns through time are then combined with observations and secondary information about change management for interpretation.

By combining these measurements with additional information about the change program in focus, the authors develop an interpretation of the dynamics of organizational change. Results showed that even in a successfully implied change effort that realize the planned targets, change does not occur directly and fully, with some elements of discourse being more persistent than others.

Method of the research presents a new way of monitoring discursive change. Its incorporation into practice potentially allows for timely correction of change efforts and increasing possibility of success.

This research provides a framework for understanding how, and to what extent, planned change efforts effect organizations. Furthermore, the method developed in this research presents an innovative approach to monitor discursive change and timely managerial intervention.

Migration of the Turkish new middle-class – high-skilled, well-educated, young professionals – has been growing in recent years. This paper explores their migration experience and discusses the role of physical and virtual bubbles in the formation of transnational communities and processes of adjustment to a new place.

This paper is based on a qualitative inquiry collecting data via semi-structured interviews with 18 London-based Turkish migrants and a digital ethnographic study of three Facebook groups that bring together the Turkish migrant community in Richmond, London.

Findings indicate that the migration of the new middle class differs conceptually from existing typologies. The paper proposes the concept of “dissonant harmony-seekers” and elaborates on their interactions to demonstrate that, in the Internet age, the traditional image of migrants living in isolated localised bubbles is no longer accurate. Findings also indicate a pragmatic and functional engagement with the bubbles, with migrants sporadically interacting with the bubbles to meet their individual needs in information, education and employment. 

This paper contributes to the literature with the concept of dissonant harmony-seekers, which will gain more visibility in a world where the trend of democratic decline and rising authoritarianism will motivate a migratory move for people who confront a moral dissociation from the civil order in their homeland. The engagement of dissonant harmony-seekers with migrant communities challenges the conventional thinking that social identity is central to creating and maintaining bubbles. The other contribution of the paper to the literature is the metaphor of “foam” to capture the ephemeral and fugacious nature of the dynamics of migrant communities and practices.

The purpose of the study is to provide a dataset about geometrical constructions of early Ottoman tombs for conservation studies. Thus, a proposal for the restitution phase of the damaged tombs aims to develop.

The study is composed of four phases. First, the representative plan and section drawings of early Ottoman Tombs were redrawn; second, a geometrical analysis was made, a proposal table was prepared for the restitution of the damaged tombs; and last, this table was applied to tomb examples and restitution drawings are verified with the original situation of the tombs.

Early Ottoman tombs may be interpreted through geometric shapes, including the square, circle, triangle, octagon, arsin grid and quadrature systems. The arsin grid system provides information about the position of the domes and the height of the drums and windows. Quadrature establishes the highest point of domes and entrances. The proposal table, developed from the obtained results, facilitated the identification of the original elements, including the dome, drum, window and portal. This information is crucial for conducting further studies on restitution.

The abundance and dispersed nature of tomb structures compared to other architectural designs pose challenges in their scholarly examination. The early Ottoman tombs, which experienced an increase in numbers following the Conquest of Istanbul, serve as the initial expressions and embodiments of novel architectural endeavors. Thus, the determination of design ideas of the early Ottoman tombs sheds light on Ottoman architectural practice, which has remained largely unknown and guided the conservation studies of the tombs that have lost their integrity and originality.

In Turkey, dependence on foreign countries for energy is a problem which upsets all economic balances. Turkey’s biggest fossil energy source is lignite coal. Therefore, energy conversion of lignite in thermal plants, causing minimum environmental effect is extremely important. The basic problem in terms of the combustion technology is to improve the combustion technology that can burn the low-qualified fuels that do not have standard fuel features (lignite, peat, schist). The most suitable technology today for the efficient and clean combustion of nonstandard low-qualified fuels is the combustion at fluidized-bed technology. In this study, CO₂ emission that occurs during the combustion of Orhaneli coal that is one of our native low-qualified lignite, has been investigated according to the experimental study.

For this combustion experiment, laboratory-scaled circulating fluidized-bed (CFB) process that exists at TÜBITAK-MAM Energy Institute which has been designed and used before has been used. The effect of excess-air coefficient, combustion type and bed temperature to the greenhouse gas formation and CO₂ emission has been investigated experimentally. In terms of flue gas emissions, it has been detected that the decrease of the amount of CO₂ that has occurred has no positive effects on combustion efficiency, water vapor, SO₂, NO_x, CO and other gases which occur during deficient combustion must be thought as a whole and each reaction affects each other similar to complex reactions.

As a consequence of measuring CO₂ emissions over 10 minute periods, CO₂ emissions are 12.43 percent average, CO₂ decreases at different air coefficient values; Often form undesirable side reactions such as CO, NOx with back and forth reactions.

The importance of aerodynamic structure of the system, and the losses and leakages forming in the system has been observed experimental and affected parameters are evaluated.

Rabbit chase (RC) is used as one of the most effective techniques in manufacturing systems, as such systems have high level of adaptability and increased productivity in addition to providing uniform workload balancing and skill improving environment. In assembly systems, RC inspires the development of walking worker assembly line (WWAL). On the other hand, U-type assembly lines (UALs) may provide higher worker utilization, lower space requirement and more convenient internal logistics when compared to straight assembly lines. In this context, this study aims to improve assembly line performance by generating RC cycles on WWAL with respect to task assignment characteristics of UAL within reasonable walking distance and space requirement. Therefore, a novel line configuration, namely, segmented rabbit chase-oriented U-type assembly line (SRCUAL), emerges.

The mathematical programming approach treats SRCUAL balancing problem in a hierarchical manner to decrease computational burden. Firstly, segments are generated via the first linear programming model in the solution approach for balancing SRCUALs to minimize total number of workers. Then, stations are determined within each segment for forward and backward sections separately using two different pre-emptive goal programming models. Moreover, three heuristics are developed to provide solution quality with computational efficiency.

The proposed mathematical programming approach is applied to the light-emitting diode (LED) luminaire assembly section of a manufacturing company. The adaptation of SRCUAL decreased the number of workers by 15.4% and the space requirement by 17.7% for LED luminaire assembly system when compared to UAL. Moreover, satisfactory results for the proposed heuristics were obtained in terms of deviation from lower bound, especially for SRCUAL heuristics I and II. Moreover, the results indicate that the integration of RC not only decreased the number of workers in 40.28% (29 instances) of test problems in U-lines, but also yielded less number of buffer points (48.48%) with lower workload deviation (75%) among workers in terms of coefficient of variation.

This study provides convenience for capacity management (assessing capacity and adjusting capacity by changing the number of workers) for industrial SRCUAL applications. Meanwhile, SRCUAL applications give the opportunity to increase the capacity for a product or transfer the saved capacity to the assembly of other products. As it is possible to provide one-piece flow with equal workloads via walking workers, SRCUAL has the potential for quick realization of defects and better lead time performance.

To the best of the authors’ knowledge, forward–backward task assignments in U-type lines have not been adapted to WWALs. Moreover, as workers travel overall the line in WWALs, walking time increases drastically. Addressing this research gap and limitation, the main innovative aspect of this study can be considered as the proposal of a new line design (i.e. SRCUAL) which is sourced from the hybridization of UALs and WWAL as well as the segmentation of the line with RC cycles. The superiority of SRCUAL over WWAL and UAL was also discussed. Moreover, operating systematic for SRCUAL was devised. As for methodical aspect, this study is the first attempt to solve the balancing problem for SRCUAL design.

This study aims to examine changes in the discourse concerning Israeli tourism to Turkey between 2000 and 2014.

Drawing on the concept of geographic imagination and using a critical cultural discourse analysis of travel stories published in the Israeli media, the authors analyze the extent to which changes have both reflected and resulted from changing relations between the two countries.

The analysis reveals that before 2010, Turkey was depicted in largely positive geo-cultural terms, imagined as a desired cosmopolitan, culturally “authentic” destination, which elicits feelings of joy and peacefulness. More recent narratives, however, highlighted its negative geopolitical qualities, underscoring its anti-Israel stance and invoking a fearful discourse of political and ethno-religious radicalization.

The study makes three contributions. First, by attending to the significance of perceptions in the social construction of tourist destinations it brings the fields of tourism and cognitive geography into a closer dialogue. Second, by using a critical discourse analysis it highlights the changing cultural contexts within which places are imagined and constructed by tourists. Finally, by uncovering the geographic complexities that undergird the discursive construction of places as tourist destinations, it illustrates how everyday narratives change over time, reflecting the dynamic nature of inter-state relations.
