Traditional oxide glasses occur naturally as obsidian and can be made easily by suitable cooling histories. In the past 30 years, a variety of techniques have been discovered which amorphize normally crystalline materials such as metals. These include [1-3]:Rapid quenching from the vapor phase.Rapid quenching from the liquid phase.Electrodeposition of certain alloys, e.g. Fe-P.Oxidation of crystals to produce amorphous surface oxide layers.Interdiffusion of two pure crystalline metals.Hydrogen-induced vitrification of an intermetal1ic.Mechanical alloying and ball-milling of intermetal lie compounds.Irradiation processes of all kinds using ions, electrons, neutrons, and fission products.We offer here some general comments on the use of TEM to study these materials and give some particular examples of such studies.Thin specimens can be prepared from bulk homogeneous materials in the usual way. Most often, however, amorphous materials are in the form of surface films or interfacial films with different chemistry from the substrates.

The paper deals with theoretical approaches to the problems of property rights and contractual obligations and with analysis of economic consequences of the imperfect enforcement system. In particular, the authors consider Russian experience in the sphere of corporate conflicts. Legal and practical recommendations related to the improvement of legal framework, judiciary reform, executory process and different federal and regional authorities are also presented.

This paper is devoted to the estimation of welfare costs of inflation, taking into account the peculiarities of the Russian economy. Theoretical approaches that are used in the literature to analyze the costs of inflation are discussed in the paper. It also provides an overview of the empirical studies of this topic. Research found in academic literature shows that the results of quantitative estimates are extremely sensitive to the choice of the functional form of the money demand equation, as well as to assumptions that are made to simplify the analysis, some of which do not fit Russian data. As a result, we have modified the standard approaches to estimating welfare costs of inflation, taking into account the monetization growth in Russia, and provide quantitative estimates of the magnitude of welfare costs of inflation. The results indicate a significant gain for economic agents in terms of real GDP with a decrease in inflation, which is regarded as a positive effect from the inflation targeting policy.

Helping Others

The paper documents the initiative of two African American women educators who have utilized these theoretical approaches to solve the educational challenges in their respective communities. Marva Collins and Corla Hawkins decided to build schools in their own communities after realizing that the public schools were not equipped to educate minorities. The story of these two women demonstrates that individuals can address systemic injustices in their communities. Collins and Hawkins were not wealthy. What they possessed was a passion for helping others. Their example can inspire more individuals to take steps using liberating philosophies, like value-creating education and womanist approaches in education, to transform the state of education in their communities.

Means Of Production

This article explores the sources of legitimacy of private property in the means of production in Ukraine. The conceptualization of legitimacy of private property was made by analyzing theoretical approaches to the study of the foundations of private property relations in Western countries. The application of these approaches tests economic utilitarian, psychological, and sociocultural explanations of legitimacy of large and small private enterprises and private land in the process of activation of post-communist transition of Ukrainian society. The basic hypothesis was that the process of legitimation of private property in the means of production proceeds by uniting utilitarian and psychological adaptation with sociocultural agreement of ideological attitudes. This hypothesis was verified with the help of created legitimacy indices by comparison of linear regressions and data of the Institute of Sociology of the National Academy of Sciences (NAS) of Ukraine for 2013 and 2017. The results indicate that the hypothesis has been held true only concerning legitimacy of small private enterprises. They have acquired a moderate extent of legitimacy owing to the fact that besides the factors of adaptation, social recognition has increased at the expense of people who support the multiparty system and the liberal and mixed methods of regulation of the economy. In contrast, the existence of large private enterprises and private land has not acquired the corresponding sociocultural foundation.
