Реферат: Методами растровой электронной микроскопии, электросопротивления и термодесорбции исследованы особенности накопления гелия в молибденовых фольгах, полученных различными методами при облучении ионами гелия с энергией 40 кэВ. Установлено, что гелий находится в порах, образованных на поверхности молибдена после холодной прокатки, а в случае применения полугорячего деформирования связан вакансионными кластерами, стабильными до температур 400-700 С.
Peculiarities of high-current electron beam effect on the structure of Ni-Ti alloy surface implanted by krypton ions

Реферат: The paper represents the results of experimental research of the structure of Ni-Ti alloy surface with the shape memory effect, consistently modified by krypton heavy ions with the energies of 280 keV and 1.75 MeV/a.m.u. and high-current electron beam in the mode of surface layer melting. It was found that interaction of 86Kr heavy ions of high energy with the polished surface of the alloy forms hemispherical convex structures (globules) up to 200 nm, associated with the accumulation of implanted ions, concentration of which increases with increasing implantation fluence. However, the process of globules formation is accompanied by the formation of structural elements typical for the sputtering process at low fluences and is prevalent at high fluences. In the case of 86Kr ions of low energy implantation only the structures of surface sputtering can be observed even at the fluence of 1021 ion/m2. It is established that the observed softening of the Ni-Ti alloy surface layer resulted from implantation of 86Kr heavy ions of both energies is connected to sputtering of the oxide layer and occurrence of radiation-stimulated phase transition \"martensite austenite\". After secondary treatment by high-current electron beam the almost uniform distribution of the globules of 15?23 nm size is observed on the surface of the alloy implanted by 86Kr ions of low energy and slight refinement of the globules and large heterogeneity in their distribution after implantation by 86Kr ions of high energy. The additional softening of the Ni-Ti alloy surface is connected, apparently, with the melting of columnar structures, typical for martensite.

Accounting for Good Governance: The Fair Value Challenge
Реферат: The purpose of this paper is to describe and analyze the accounting standards reforms that have moved the accounting profession away from rules-based towards principles-based accounting practice and financial reporting, and to explore the implications for boards of directors of fair value estimates of the unknowable contaminating financial statements with financial misstatements. The paper critically reviews the internationally accepted accounting, auditing and financial reporting standards with respect to fair value accounting and relates them to directors\' fiduciary duties - the duties of care, of oversight, and of obedience. This paper\'s originality is grounded in its exploration of the epistemology of accounting in the light of the adoption of fair value conventions in the internationally accepted accounting, auditing and financial reporting standards and its drawing out of the implications this has for corporate governance.
Delivering Environmental Education in Kazakhstan Through Civic Action: Second-Wave Values and Governmental Responses

Реферат: The severity of Kazakhstan\'s ecological problems impels civic activists and state agencies to build public support for ecological rehabilitation in the country, through a comprehensive national programme of environmental education. This paper is a qualitative analysis whose main focus is the relations of civic groups and NGOs with the national government, occurring in the delivery of programmes for environmental education during the post-glasnost era. Provisional successes of civic groups in establishing environmental education programmes, and useful steps by the government to facilitate civic environmental activism, give reasons for optimism for improved environmental governance.
Реферат: This research represents an exploratory analysis of Kazakhstani B.Sc. student personal values. Students were given a list of items each of which represents a personal value in the following areas: professional, financial, family, social, community, spiritual, physical, or intellectual. The students had to rate how important each one is to them using a 5-point Likert-type scale. The findings indicate that students majoring in accounting rated all items higher than did students majoring in management; all business students - irrespective of their major - exhibited a strong desire to maintain a work-life balance, a weak desire to serve for the benefit of community, and a relatively low spiritual need. The academic and practical contribution of this article is that it gives an insight into an under-researched topic of personal values of today\'s business students who tomorrow will become business leaders and business managers of young and perspective state of Kazakhstan.
Analyzing long-term university enrollment dynamics using a Monte Carlo method

Ключевые слова: управление высшим образованием*метод Монте-Карло*долгосрочный прогноз зачисления студентов*
Реферат: The Monte Carlo method is a powerful computational tool for estimating systems of mathematical equations that might be difficult to solve analytically. Since the enrollment dynamic of a university can be modeled with a small number of relatively simple equations, the Monte Carlo can be used as an approximate solver. This process is deterministic, making this method suitable for long-term forecasting only as long as the model\'s parameters are assumed to be constant over long horizons. Additional tests of the simulated enrolment data are also included, as they illustrate fundamental relationships existing among the variables in the model.
Testing Conventional And Ex Ante Purchasing Power Parity: The Case of three CIS Currencies
Ключевые слова: паритет покупательной способности валют*обменный курс*международные финансовые рынки*
Реферат: This paper tests whether conventional or ex ante purchasing power parity holds for the exchange rates of the three CIS currencies - Kazakh tenge, Kyrgyz som and Russian Ruble - vis-a-vis the US dollar and for the exchange rates of Kazakh tenge and Kyrgyz som vis-a-vis the Russian Ruble over the period 1995m1-2010m6. Results obtained by employing two residual-based cointegration tests of Engle and Granger (1987) and Phillips and Ouliaris (1990) and coefficient restrictions tests based on the West (1988) corrected t-statistic lend strong support to ex ante PPP against conventional one. These results suggest that the real exchange rate for the underlying currency combinations is not stationary; rather it follows a random walk. This also implies that PPP does not hold for the three CIS currencies even in the long run.
