"Information-Based Economy" and Educational System

"Information-Based Economy", which is today's economy that is a proof and indicator of development level for the countries now on, comes on the scene with its new organizing model on its infrastructure, which is called "Information Society". The phenomenon of administration introduces to "e-Government" for reinforcing the roots of "Information-Based Economy" now. Having a systematic knowledge of the relation between "Information-Based Economy", "Information Society" and "e-Government" as a whole composes of the theme of this study. For this purpose, a questionnaire has been conducted in the Ministry of National Education, which is responsible for forming the society of the future, to understand whether there is a systematic knowledge on the relation between "Information-Based Economy", "Information Society" and "e-Government" as a whole. Moreover, it has been aimed to discover what the mental formulations of participants are. Questionnaire results reveal that there is no systematic knowledge on the relation between "Information-Based Economy", "Information Society" and "e-Government" as a whole in the Ministry of National Education, and that the participants are apt to perceive "e-Government" within the context in which they are in terms of professions, status and backgrounds. Questionnaire results also show that the responses given by the participants concerning "e-Government" are more or less the same due to the hierarchical organization of knowledge and official knowledge in particular.Information-Based Economy, Information Society, E-Government, Educational System

International Financial Instability in a World of Currencies Hierarchy

The 1990s have witnessed an increase of international financial turbulence. Indeed, the frequency, the size, the geographic extension, and the social costs of financial crises have made the topic a global policy issue. An array of policy actions have been advocated to prevent crises from happening again. A major controversial question is whether efforts should be directed towards national reforms in emerging markets or, rather, towards a new international design of international payments. After a critical review of the standing proposals, this paper contends that this debate has not yet fully explored one of the problems of international instability, that is to say, the problem raised by international payments in a world of currencies of diverse quality. As Keynes firmly contended, the monetary side of the (global) economy is not a neutral factor. In fact, it may be the problems posed by the different degrees of “international moneyness” that make currencies unequal that should be considered as one of the fundamental factors behind any model of international financial instability. Viewed in this light, a major re-design of international payments systems is warranted, and options seem limited to either world dollarization or the ‘bancor’ solution. Recent reformulations of Keynes’s original ‘bancor’ proposal seem to be a more viable alternative to either the status quo or world dollarization.Currency hierarchy; Currency crises; Banking crises; Capital flows; International monetary arrangements and institutions.

"The "Keynesian Moment" in Policymaking, the Perils Ahead, and a Flow-of-funds Interpretation of Fiscal Policy"

With the global crisis, the policy stance around the world has been shaken by massive government and central bank efforts to prevent the meltdown of markets, banks, and the economy. Fiscal packages, in varied sizes, have been adopted throughout the world after years of proclaimed fiscal containment. This change in policy regime, though dubbed the "Keynesian moment," is a "short-run fix" that reflects temporary acceptance of fiscal deficits at a time of political emergency, and contrasts with John Maynard Keynes’s long-run policy propositions. More important, it is doomed to be ineffective if the degree of tolerance of fiscal deficits is too low for full employment. Keynes’s view that outside the gold standard fiscal policies face real, not financial, constraints is illustrated by means of a simple flow-of-funds model. This shows that government deficits do not take financial resources from the private sector, and that demand for net financial savings by the private sector can be met by a rising trade surplus at the cost of reduced consumption, or by a rising government deficit financed by the monopoly supply of central bank credit. Fiscal deficits can thus be considered functional to the objective of supplying the private sector with a provision of financial wealth sufficient to restore demand. By contrast, tax hikes and/or spending cuts aimed at reducing the public deficit lower the available savings of the private sector, and, if adopted too soon, will force the adjustment by way of a reduction of demand and standard of living. This notion, however, is not applicable to the euro area, where constraints have been deliberately created that limit public deficits and the supply of central bank credit, thus introducing national solvency risks. This is a crucial flaw in the institutional structure of Euroland, where monetary sovereignty has been removed from all existing fiscal authorities. Absent a reassessment of its design, the euro area is facing a deflationary tendency that may further erode the economic welfare of the region.Government and the Monetary System; Fiscal Policy; Keynes; Euro Area

Analyzing urban sprawl patterns through fractal geometry: the case of Istanbul metropolitan area

Over the last decade, there has been a rapid increase in the amount of literature on the measurement of urban sprawl. Density gradients, sprawl indexes which are based on a series of measurable indicators and certain simulation techniques are some quantitative approaches used in previous studies. Recently, fractal analysis has been used in analyzing urban areas and a fractal theory of cities has been proposed. This study attempts to measure urban sprawl using a sprawl index and analyses urban form through fractal analysis for characterizing urban sprawl in Istanbul which has not been measured or characterized yet. In this study, measures of sprawl were calculated at each neighborhood level and then integrated within sprawl index through “density” and “proximity” factors. This identifies the pattern of urban sprawl during six periods from 1975 to 2005, and then the urban form of Istanbul is quantified through fractal analysis in given periods in the context of sprawl dynamics. Our findings suggest that the fractal dimension of urban form is positively correlated with the urban sprawl index score when urban growth pattern is more likely “concentrated”. However, a negative relationship has been observed between fractal dimension and sprawl index score when the urban growth pattern changes from the concentrated to the semi-linear form

Stock-bond correlation and the bond quality ratio: Removing the discount factor to generate a “deflated” stock index

This paper investigates the cyclical co-movements between US stocks and interest rates by testing a simple model where divergence between stock and bond price behavior is explained by “stock market strength,” where the latter depends on the market climate about future corporate profits—as captured by the corporate bond quality ratio—and an unexplained stock market sentiment. Using two different regression techniques to check for robustness, we find evidence of a statistically significant cyclical correlation between stocks and bonds. On the basis of this finding, we then present a methodology to “deflate” a stock price index such that we can compare stock market strength over time. This is obtained by removing the effect of a changing discount rate—as measured by our regressions—on stock prices. For example, viewed in this light, the past five years in the US stock market reveal a wider fluctuation in stock market strength than we can observe on the basis of stock price indices alone.Stock-bond correlation, Market sentiment, Stock price.

Targeted matrix completion

Matrix completion is a problem that arises in many data-analysis settings where the input consists of a partially-observed matrix (e.g., recommender systems, traffic matrix analysis etc.). Classical approaches to matrix completion assume that the input partially-observed matrix is low rank. The success of these methods depends on the number of observed entries and the rank of the matrix; the larger the rank, the more entries need to be observed in order to accurately complete the matrix. In this paper, we deal with matrices that are not necessarily low rank themselves, but rather they contain low-rank submatrices. We propose Targeted, which is a general framework for completing such matrices. In this framework, we first extract the low-rank submatrices and then apply a matrix-completion algorithm to these low-rank submatrices as well as the remainder matrix separately. Although for the completion itself we use state-of-the-art completion methods, our results demonstrate that Targeted achieves significantly smaller reconstruction errors than other classical matrix-completion methods. One of the key technical contributions of the paper lies in the identification of the low-rank submatrices from the input partially-observed matrices.Comment: Proceedings of the 2017 SIAM International Conference on Data Mining (SDM

Determination of benzo[alpha]pyrene in Turkish döner kebab samples cooked with charcoal or gas fire

peer-reviewedIn order to investigate the levels of the potent carcinogen benzo[a]pyrene (B(a)P), 40 samples of döner kebab were analysed. The samples tested included 20 cooked using a charcoal fire and 20 cooked using a gas fire. A liquid chromatographic method was developed using a fluorescence detector. The mean levels of B(a)P were found to be 24.2 (s.e. 0.84) g/kg for charcoal fire cooked meat samples and 5.7 (s.e. 3.48 g/kg) for gas fire cooked meat samples. Sixteen samples were found to be over the maximum level recommended by FAO/WHO (10 g/kg) and all of the samples exceeded the maximum tolerance level of the Turkish Food Codex (1 g/kg)
