Обозначена значимость состояния российской экономики и отраслей пищевой промышленности в решении проблем социально-экономического благополучия граждан. Рассмотрено влияние ресурсной декомпенсации в создании предпосылок для управления конкурентоспособностью производственного комплекса. Введено в научный оборот понятие маркетингово-поведенческой миопатии, обозначающей процесс нарушения маркетинговых и поведенческих реакций субъектов в результате модуляционных воздействий от субъектов внешнего окружения и приводящей к усилению внутренней инерционности трудового ресурса на разработку и реализацию инновационных решений и торможению экономического роста пищевой промышленности. Реструктуризационные преобразования на инновационной основе в цепочках создания стоимостей способны обеспечить субъектам производственной сферы в отраслевых сегментах региональной экономики укрепление их конкурентных позиций даже в условиях нестабильной экономики и наличия противоречий разного характера. Аргументировано, что ресурсный дефлектор обладает дихотомическими свойствами, присущими ему как инструменту управления ресурсами и катализатору построения рациональных коммуникационных взаимодействий в процессах реструктуризационных преобразований. Ресурсный дефлектор как драйвер экономического роста бизнеса в производственной сфере пищевой промышленности интегрирован в предлагаемую модель антикризисного управления конкурентоспособностью производственного комплекса, что создает предпосылки эффективной реализации инновационных изменений его составляющих. The importance of the state of the Russian economy and the food industry in solving the problems of the socio-economic well-being of citizens is indicated. The influence of resource decompensation in creating prerequisites for managing the competitiveness of the industrial complex is considered. The concept of marketing-behavioral myopathy has been introduced into scientific circulation, which denotes the process of violation of marketing and behavioral reactions of subjects as a result of modulation influences from subjects of the external environment and leading to an increase in the internal inertia of the labor resource in the development and implementation of innovative solutions and to the inhibition of economic growth in the production area of the food industry. Restructuring transformations on the basis of innovation in value chains can provide the subjects of the production sector in the industry segments of the regional economy with the strengthening of their competitive positions, even in an unstable economy and the presence of contradictions of various kinds. It is argued that the resource deflector has dichotomous properties inherent in it as a tool for resource management and as a catalyst for building rational communication interactions in the processes of restructuring transformations. The resource deflector as a driver of economic growth of business in the food industry is integrated into the proposed model of anti-crisis management of the competitiveness of the production complex, creating prerequisites for the effective implementation of innovative changes in its components.

AbstractWhen internal (inertia-)gravity waves propagate in a vertically sheared geostrophic (eddying or mean) flow, they exchange energy with the flow. A novel concept parameterizing internal wave–mean flow interaction in ocean circulation models is demonstrated, based on the description of the entire wave field by the wave-energy density in physical and wavenumber space and its prognostic computation by the radiative transfer equation. The concept enables a simplification of the radiative transfer equation with a small number of reasonable assumptions and a derivation of simple but consistent parameterizations in terms of spectrally integrated energy compartments that are used as prognostic model variables. The effect of the waves on the mean flow in this paradigm is in accordance with the nonacceleration theorem: only in the presence of dissipation do waves globally exchange energy with the mean flow in the time mean. The exchange can have either direction. These basic features of wave–mean flow interaction are theoretically derived in a Wentzel–Kramers–Brillouin (WKB) approximation of the wave dynamics and confirmed in a suite of numerical experiments with unidirectional shear flow.

AbstractIce bands are frequently observed over marginal ice zones in polar seas. A typical ice-band pattern has a regular spacing of about 10 km and extends over 100 km in the marginal ice zone. Further, the long axis of an ice band lies to the left (right) with respect to the wind direction in the Northern (Southern) Hemisphere. Here, the study shows that the resonance between ice-band pattern propagation and internal inertia–gravity waves below the sea ice well explains the ice-band pattern formation. Internal waves are generated by the difference between the stress on the open water and the stress on ice-covered water. This in turn reinforces the formation of an ice-band pattern with a regular band spacing. Specifically, the authors have found the following: 1) A band spacing on the order of 10 km is selected by the resonance condition in which the ice-band pattern propagation speed coincides with the phase speed of internal inertia–gravity waves. 2) The ice bands tend to develop favorably when the wind direction and the band propagation direction are nearly parallel. The velocity acceleration caused by the periodic differential stress associated with the ice bands, driven by the wind parallel to the band propagation direction, is important. The wind direction may turn to the left (right) slightly in the Northern (Southern) Hemisphere as a result of the Coriolis force acting on ice. Satellite images confirmed that the band spacing of the ice-band pattern in the polar seas is consistent with this theory.

Purpose – The aim of this paper is to present the challenges external drivers and internal inertia faced by curriculum designers and implementers at institutions of higher education. The challenges to academics from competing factors are presented: internal resistance to changing existing curricula vs the necessity to continuously evolve programmes to reflect a dynamic, uncertain future. The necessity to prepare future leaders to face global issues such as climate change, dictates changing curricula to reflect changing personal, environmental and societal needs. Design/methodology/approach – This paper uses the case study method to examine two models of climate change curriculum design and renewal. One model, from an Australian university, is based upon national education standards and the second is a non-standards-based curriculum design, developed and delivered by a partnership of four North American universities. Findings – The key findings from this study are that the highest level of participation by internal-to-the-programme academics and administrators is required. Programme quality, delivery and content alignment may be compromised with either stand-alone course delivery and learning outcomes, or if courses are developed independently of others in the programme. National educational standards can be effective tools to guide course and programme management, monitoring, review and updating. Practical implications – The paper includes implications for postgraduate level curricula design, implementation and programme evaluation. Originality/value – The paper is the first to compare, contrast and critique a national standards-based, higher education curriculum and a non-standards-based curriculum.

The idea of inertial propulsion using rotating parts is always attractive, but great controversy also exists. Some researchers even completely negate this idea in principle, they think it would never be possible to create directional movement by the inertial force. Theory and experimental results show that, in certain conditions, directional movement can be realized by the internal inertia force of the device. In this paper, the influence of the friction condition between the propulsion devices which using rotating eccentric mass to generate inertia force and the external supporting surface on the effect of propulsion has been analyzed. The results show that, when there is friction between the device and the supporting surface, the rotary of eccentric mass in the device will allow the device to produce motion in a given direction; if the parameters of propulsion device (eccentric mass and eccentricity) and the rotary speed of the eccentric mass are given, the friction condition between the device and the support surface will affect the characteristics of directional motion.

It is state of the art that muscle contraction dynamics is adequately described by a hyperbolic relation between muscle force and contraction velocity (Hill relation), thereby neglecting muscle internal mass inertia (first-order dynamics). Accordingly, the vast majority of modelling approaches also neglect muscle internal inertia. Assuming that such first-order contraction dynamics yet interacts with muscle internal mass distribution, this study investigates two questions: (i) what is the time scale on which the muscle responds to a force step? (ii) How does this response scale with muscle design parameters? Thereto, we simulated accelerated contractions of alternating sequences of Hill-type contractile elements and point masses. We found that in a typical small muscle the force levels off after about 0.2 ms, contraction velocity after about 0.5 ms. In an upscaled version representing bigger mammals' muscles, the force levels off after about 20 ms, and the theoretically expected maximum contraction velocity is not reached. We conclude (i) that it may be indispensable to introduce second-order contributions into muscle models to understand high-frequency muscle responses, particularly in bigger muscles. Additionally, (ii) constructing more elaborate measuring devices seems to be worthwhile to distinguish viscoelastic and inertia properties in rapid contractile responses of muscles.
