Innovation performance and competitive strategies in the Turkish manufacturing industry

In this paper, we report on empirical investigation within the context of the Innovations in Manufacturing Industries in Turkey Study 2004/2005. The data was gathered in nine different cities in Turkey during the period August 2004 – January 2005. The survey was conducted through face-to-face interviews due to the complex nature of the survey and was implemented in 135 manufacturing firms operating in four sectors: Textiles, chemicals, food, and metal. The study has been an extension of the European Manufacturing Survey 2004 (EMS 2004) coordinated by the Fraunhofer Institute for Systems and Innovation Research and covering nine countries: Germany, Turkey, Austria, Switzerland, France, Slovenia, Croatia, Italy, and United Kingdom. An extended version of the questionnaire form used in EMS 2004 has been employed. Some of the basic results concerning competitive priorities, new product development, and operations management are presented

An Empirical study on the competitiveness and innovation in four sectors of the Turkish manufacturing industry

In this paper, we report on some of the results of the Innovations in Manufacturing Industries in Turkey Study (IMITS). This study is an empirical investigation into the innovation performance and competitive strategies of manufacturing firms in Turkey. The data was gathered in nine different cities in Turkey during the period August 2004 – January 2005. The survey was conducted through face-to-face interviews due to the complex nature of the survey and was implemented in 135 manufacturing firms operating in four sectors: Textiles, chemicals, food processing, and metal. The study has been an extension of the European Manufacturing Survey 2004 (EMS 2004) coordinated by the Fraunhofer Institute for Systems and Innovation Research and covering nine countries: Germany, Turkey, Austria, Switzerland, France, Slovenia, Croatia, Italy, and United Kingdom. Some of the basic results concerning competitive priorities, modernization of manufacturing, new product development, and quality management are presented

The vulnerability of the low-skilled

The low-skilled are a critical category for analyses of labour market marginalization. Class analysis has tended to depict low-skilled employees as sharing a broadly similar position with respect to both employment and labour market conditions. Their employment relationship is defined by a specific type of contract – the labour contract – characterized by precarious pay, low asset specificity and high job insecurity. This contrasts with employees who benefit from a service relationship which is designed to bind employees to the organization on a longer term basis. Recent neo-institutional theories however have emphasized the diversity of employment conditions between advanced capitalist societies, depending in particular on the nature of their production, employment and welfare regimes. An important issue is whether such divergences apply only to more skilled categories of the workforce (and hence lead to accentuated polarization) or also affect the employment conditions of the low-skilled. Are the low-skilled significantly more integrated into the labour market in some countries than in others and hence less vulnerable in times of economic restructuring? The paper will examine this by comparing a number of EU-15 countries that have been regarded as reflecting contrasting institutional regimes. It will focus in particular on the position of the low-skilled with respect to pay, training and job security

Development of artificial cell culture platforms using microfluidics

Acquiring quantitative data about cells, cell-cell interactions and cellular responses to surrounding environments are crucial for medical diagnostics, treatment and cell biology research. Nowadays, this is possible through microfluidic cell culture platforms. These devices, lab-on-a-chip (LOC), are capable of culturing cells with the feature of mimicking in vivo cellular conditions. Through the control of fluids in small volumes, LOC closely mimics the nature of cells in the tissues compared to conventional cell culturing platforms such as flasks and cell culture plates. On the other hand, existing LOC-based cell culturing platforms are highly complicated to be used in clinics or laboratories without an expert who develops these microfluidic platforms. Therefore, in this thesis we developed simple and user-friendly microfluidic cell culturing platforms and compared our obtained data with the conventional methods. We performed our research on different human cancer cell lines including liver hepatocellular carcinoma, breast adenocarcinoma, and lymphoma cell lines; both monocytes and monocyte-differentiated macrophages. We examined proliferation rate, morphological and phenotypical differences of the cells in different scales. In addition to cell culturing platform, we developed a microfluidic gradient generator to precisely titrate the concentration of chemicals and observed cellular responses to these stresses. Moreover, we quantitatively inspected the effect of different intravenous fluids on different human cancer cell lines. Finally, we have developed simple, low-cost and integrable microfluidic platforms, those can be used by untrained people, and perform cell culture experiments in a population at single-cell resolution. Our microfluidic cell culture platforms provide more quantitative and qualitative data compared to traditional batch culture assay

A Deep Incremental Boltzmann Machine for Modeling Context in Robots

Context is an essential capability for robots that are to be as adaptive as possible in challenging environments. Although there are many context modeling efforts, they assume a fixed structure and number of contexts. In this paper, we propose an incremental deep model that extends Restricted Boltzmann Machines. Our model gets one scene at a time, and gradually extends the contextual model when necessary, either by adding a new context or a new context layer to form a hierarchy. We show on a scene classification benchmark that our method converges to a good estimate of the contexts of the scenes, and performs better or on-par on several tasks compared to other incremental models or non-incremental models.Comment: 6 pages, 5 figures, International Conference on Robotics and Automation (ICRA 2018

Relative Price Variability : The Case of Turkey 1994-2002

Relative price variability leads to inefficiencies in the allocation of resources that reduce real income (Fischer, 1981). Given the costs associated with relative price variability, the relation between inflation and relative price variability was extensively researched and a positive relation between the two was documented for many countries and for varying time periods. Furthermore, one of the main sources of relative price variability being differential speeds of price adjustment in different sub-sectors, renders the investigation of relative price variability valuable also in terms of understanding the inflationary dynamics. In this paper, highly disaggregated data based on 103 classification of Turkish CPI for the period between January 1994 and December 2002 are utilised. The statistical findings based on Theil (1967) measure of relative price variability, are analyzed from different perspectives : seasonal pattern, time aggregation, different sub-groups, e.g. tradable/non-tradable prices, administered/non-administered prices etc. Resulting stylized facts about recent dynamics of inflation are presented. The relation between relative price variability and inflation is verified by carrying out model-free regressions. The results show that there is a positive contemporaneous association between relative price variability and inflation in Turkey. Besides, inflation is found to Granger-cause relative price variability. These conclusions are shown to be robust to the degree of commodity aggregation.Relative Price Variability, Inflation, Turkish Inflation

Portfolio Allocation and International Risk Sharing

Recent contributions have shown that it is possible to account for the so-called consumption-real exchange anomaly in models with goods market frictions where international asset trade is limited to a riskless bond. In this paper, we consider a more realistic international asset market structure and show that as soon as we depart from the single bond economy, we can no longer account for the consumption-real exchange anomaly. Our central result holds for a simple asset market structure in which two nominal bonds are traded across countries. We explore the role of demand shocks such as news shocks in generating meaningful market incompleteness. We show that only under specific settings news shocks can improve the performance of the model in matching the portfolio positions and consumption-real exchange rate correlations that we observe in the data.Portfolio choice, incomplete financial markets, international risk sharing, consumption-real exchange rate anomaly
