To better deal with these conditions, a compound control strategy based on a support vector machine （SVM） with inverse identification was proposed and applied to research simulating coordinated control systems. This method combines SVM inverse control and fuzzy control, taking advantage of the merits of SVM inverse controls which can be designed easily and have high reliability, and those of fuzzy controls, which respond rapidly and have good anti-jamming capability and robustness. It ensures the controller can be controlled with near instantaneous adjustments to maintain a steady state, even if the SVM is not trained well. The simulation results show that the control quality of this fuzzy-SVM compound control algorithm is high, with good performance in dynamic response speed, static stability, restraint of overshoot, and robustness.展开更多

This paper presents employer branding as an approach based on effective strategic organizational resources and a precise employer branding management process. In this paper, the target is to define a possible frame in order to interpret employer branding techniques as control and regulation mechanisms. Control in organizations has long been a topic of interest for researchers and practitioners, alike who generally recognize that control mechanisms are needed to ensure that organizations may achieve their goals. It has been carried out a field work on the Italian Aeronautical Meta district, that generates annual revenues equal to EUR 8.7 billion and employees 36,300 people, of whom approximately 10% are employed in the space sector. Through this field work, the intention aim is to understand if and how employer branding may create, enforce, and set up internal and shared meaning and values. In particular, stemming from the empirical research＇s evidences, this paper tries to conceptualize employer branding as a factor to persuade and influence the way that organizational actors enact in a socially constructed context. In this effort, the aim is to understand how managers may affect meanings, values goals, and opinions through an effective action on employer branding that can play a crucial role in affecting sense-making processes, meanings, interpretations of the symbolic environment. The paper therefore opens up to new horizons, since it embraces a new application for employer branding, considering it as a modern control system and proposing an innovative approach in managerial control, founded on organizational identity as a key concept in an organizational citizenship＇s perspective展开更多

The transnationalization as a factor of government regulation mechanisms modernization was estimated and the perspectives of government and MNC interactions development in the modem world were evaluated. The recommendations for improving the government economical regulation infrastructure and mechanisms due to the conditions of economy globalizing, transnational business developing, technologies progressing were presented展开更多

The control systems try to allow to cells to optimize their state depending on the circumstances, sometimes in advance. The first of these systems is located in the root. It controls the materialistic input for the regeneration and at the same time is the source of primary information about the state of this input and its development at time. Another element of the control is the system controlling the formation and the distribution of the energy. This control is made without making provision for the state of individual cells. The successfulness of individual cells is taking into account by the system connected with companion cells in the vascular bundle. The similar holds for the second system. It, on the basis of the tension on the boundary of the plant, controls the dynamics of the boundary and removes the tension. The second goal of the control, besides the regeneration, is the optimization of the existence of the plant as whole. For this sake new global criteria arise and are used throughout the control.展开更多

There is a void that this paper would like to contribute to filling. It outlines a theoretical and empirical sociological approach to social myths as a major component of collective imaginaries and a universal sociological mechanism through time and space. The article recalls the major functions performed by myths in every society （modem as well as ＂primitive＂）, introduces new concepts, and sets forth an analytical framework designed to account for the emergence, the reproduction, and the decline of myths, as sacralised collective representations.展开更多
