The model of elastoplastic medium is based on the concept of slip proposed by Batdorf and Budiansky. The conditions of slip on a slip plane take into account “the local loading criterion”. Under some assumptions we succeeded in integrating the plastic shears over all possible slip planes in case of arbitrary three‐dimensional stress state and obtained an expression for the plastic strain tensor increments and the closed variant of the elastoplastic model, which turns out to be a variant of the plastic flow theory. The integration method proposed can be applied for establishing the links between local conditions and macroscopic equations, and for some other slip conditions too.

The model of elastoviscoplastic medium is based on the concept of slip proposed by Batdorf and Budiansky. The conditions of slip on a slip plane take into account the dependence of tangential stresses on slip velocity. But when the viscosity is low, they are almost similar to the dry friction conditions. Under some assumptions we succeeded in integrating the plastic shear rates over all possible slip planes in case of arbitrary three‐dimensional stress state and obtained an expression for the plastic strain rate tensor.

The purpose of this paper is to understand and inform the development and implementation of a newly established Discovery College (a youth-focused Recovery College). It also aims to contribute to a broader understanding of the benefits and barriers to establishing Recovery Colleges.

The overall study took a mixed-methods approach to the evaluation of Discovery College, including a qualitative process evaluation component as well as a mixed-methods outcomes evaluation. This paper reports on the findings of the process evaluation, which undertook key informant interviews with a range of stakeholders in the implementation process.

A total of 16 themes emerged from the qualitative data, which were then clustered into four main areas: establishing Discovery College, organisational context, nature of Discovery College and service transformation. Implementation was reported as both feasible and effective. Initial tension between fidelity to the model and a pragmatic approach to action was negotiated during implementation and through an ability of staff to tolerate uncertainty, enabled by the efforts and support of senior service management and college staff.

Recovery Colleges co-designed and implemented in youth mental health services are a recent development in the field of mental health care and very little has previously been published regarding the feasibility, effectiveness and acceptability of youth-focused Recovery Colleges. This paper is one of the first to assess the barriers and enablers to the implementation of Discovery College within a clinical youth mental health service.

The information for the present article was collected by the author during a two‐week visit to Moscow in the summer of 1973. The success of the visit is primarily due to the support the author received from Intourist, the USSR's organization for foreign travel, in specific from Mr. Nikitin, chief administrator of Intourist, Mr. Lebedeve, director of foreign organizations, Mr. Khodorkov, deputy director of superior courses, Mrs. Smirnowa, deputy director of permanent courses, and professors Ozira and Orlov from the Plekhanov Institute in Moscow. Information was further collected by talking to senior staff members of hotels and restaurants and to recent graduates of two of the schools.

Yet, at the beginning of the 21st century, Russia has found itself in search of a lost national identity. The communist regime has collapsed, country has broken into separate nations and it has suffered a decade of deep social reform. Russian identity inevitably is, and should be, multidimensional. Russian self-perception and self-value vis-à-vis the West is an important component of this identity. The combined (but internally split) essence of Russian civilization is often defined as Eurasian. For years, Russian civilization was a mixture of European and Asian. The School of Eurasianism, which interprets Russia’s relationship with Europe and Asia, has recently been rejuvenated, based on the work of Russian political classical thinkers like N. Danilevskyi, N. Berdyaev, L. Gumilev, L. Karsavin, V. Illyin, P. Savitskyi, and N. Trubetskoy. Classical Eurasianism is aimed at overcoming the seemingly irreconcilable contradiction between the well known Slavophil and Westerner schools. Through this dialogue, debates about Russian policy toward the West have returned (after decades of Soviet ideology), seeking a middle path between the purity of Slavophils and the extremist Westerner views.

The purpose of this paper is to show how institutional conditions affect food security at the national level.

A qualitative research with the usage of the methods of institutional, evolutionary, comparative and retrospective analysis is performed in this paper. During the study, emphasis was placed on the theory of sustainable development, the theory of economic security, the theory of economic systems and the theory of competitive advantages.

Food security policies can be based on the use of the liberal or conservative paradigm. The liberal paradigm focuses on food supply. The conservative paradigm also considers food independence. The growth of global instability has led to increased use of the conservative paradigm. Within the framework of these paradigms, four alternative models of food security have been proposed: “Pure” market, procurement, distribution, directive. For their selection, the matrix method was used. The combination of market and nonmarket management methods in the production and distribution of food is considered. Each of the models is given a meaningful interpretation, and their strengths and weaknesses are identified, the conditions of applicability and efficiency factors are indicated.

The failure of the authorities to provide the population with access to food is largely determined by institutional factors. The system of national institutions sets limits for food security. The main limitations are: technological, land, labor, infrastructure, cluster, ecological. To overcome them, it is recommended to use the tools of innovative, scientific, technological, migration, financial, investment, cluster, sustainable development and other types of state policies. Institutional shocks that lead to crises have a significant impact on food security. The study, using the example of Russia, shows that effective institutional overcoming of them is possible using the conservative paradigm.

In the literature on peace and security, we identify at least two different uses of the term Eurasia. One stakes a rather narrow geographic boundary while the second includes a much broader region. If we adopt the narrower view, Eurasia incorporates the fifteen republics of the former Soviet Union and possibly their security zones in Eastern Europe. Choosing to see Eurasia more broadly means defining it as the huge land-mass that comprises the continents of Europe and Asia. We may call the narrower definition Eurasia Minor and the broader one Eurasia Major.

Arnold Toynbee, the famous British historian and philosopher, argues that modern society should achieve a kind of universal peace in the new millennium. Toynbee asserts strongly that wars and culture clashes destroy the foundation of a civilization. He states: a comparative study of recognized civilizations all over the history shows that social destruction is a disaster whose secret hidden key could be found in the nature of war. In fact, principally, when a war is provoked by a civilization, it is also an independent cause for its destruction.

To begin, citizens of the former Soviet Republics perceive themselves to be failures. Many view the last century as a waste for Russians, an opinion shared not only among intellectuals but also among civilians. Disappointment with communism and communists has been followed by disappointment and mistrust in democracy and democrats. While Russia’s current boundary configuration and ethnic posture are new, it has retained the most painful colonial assets of Czarist Russia, primarily in the Northern Caucasus. Further, the two Chechen wars exacerbate the challenges the nation now faces and serve as a reminder that, although Vladimir Putin’s assent to power has reduced somewhat the centrifugal tendencies in Russia, the new Russian Federation is not immune to challenge.
