Инновационный подход к совершенствованию содержания и структуры управленческого образования

For the formation and development of tomorrow’s highly effective Manager model it is not already enough
 of competences from the area of only classic management and/or classic emotional and even business
 leadership. The optimum combination of universal values and strategic anticipation, social leadership,
 universal and special management technologies is necessary.
 Aspects of innovation process management on organization’s holistic development have been considered,
 main groups of higher school’s development strategies have been marked, and two types of innovative
 processes in the education system have been characterized in this paper.
 The author emphasizes that the traditional association of efforts in the training of specialists through a formal
 merger of several structures is ultimately ineffective. More productive will be the consolidation of efforts (in
 parallel with formal associations) through contractual relationships, creation of basic chairs at enterprises,
 strategic alliances, consortia, network organizations, educational and industrial groups, technology parks,
 business parks, innovative educational and industrial clusters, in other words, through creation of formal
 virtual structures.
 These chairs should become such points for growth of future organizational structures for graduates’
 training, in other words, they should become mini-academies, which will provide the high level training, and
 development of science.
 The paper talks about creation of new forms and organization experiences for training of managerial human
 resources of new generation through formal virtual structures creation with authorities, high educational
 institutions, business representatives, secondary school institutions, preschool facilities. This project
 implementation requires the allocation of several stages. The first one is creation of Institute of management
 (as faculty) as the core organizational structure in the form of high educational institution unit. A sample structure of such Institute has been proposed, the practical experience of such structures formation has
 been placed in the clearest light.
 In the process of their development the Institutions can be transformed into more complex structures (e.g.,
 academies, management universities), combining the traditional organizational structures with creation of
 strategic formally virtual associations with various educational and industrial structures at the municipal,
 regional, Federal, and international levels

The role of individual-social-technology fit in online social network value development: an empirical study

Purpose – The purpose of this study is to reveal the role of individual–social–technology fit in online social network (OSN) value development. The social software features (e.g. communication and interaction), social features (e.g. privacy and trust) and individual features (e.g. sense of belonging and self-disclosure) are considered fitting forms to describe the OSN value. Implications and suggestions are addressed. Design/methodology/approach – The literature review on social software, the social and individual characteristics and the research gap with respect to OSN value is presented. The research arguments are then hypothesized, and research model used to describe the proposed role is examined empirically. The research targeted mobile phone users as the subjects, and the extent of the activities of these users on OSN for both work and studies. A salient investigation explores the moderation effect of gender. The research results are obtained, and the findings are revealed on the basis of 468 social software users. Findings – The significant effect of individual–social–technology fit on OSN value development is presented through the satisfaction of both participation and sharing information, and knowledge about this fit is verified. The interplay of social software, social and individual features contributes significantly to individual–social–technology fit development, implying that OSN value development is not a single issue. OSN value development should be considered concurrently with technological, personal and social issues. Research limitations/implications – The empirical study confirms that fitness analysis produces a systematic outcome, in which all elements (e.g. social, technology and individual) are required to cooperate with one another to maximize the OSN value. An individual adopts online channels to communicate with others; thus, the benefits may be a multidimensional issue instead of only a single information service issue. They also consider building an equal social relationship to be important, as it enables diverse propositions, maintains acceptable privacy and behaves on faith to enhance the fit of technology features and individual features to value development. The subjects also likely accepted the fact that emotion generation is important for the advantage of fit of technology features and social features, thereby likely benefitting OSN value development. Originality/value – The OSN does not only add new values to the society but also brings new effects on social development, especially in terms of social cognition from virtual community formation, development and creation. Although existing studies in the literature present the important aspects and antecedents linked significantly to OSN value development, these studies also insufficiently discuss the effect of fit of these facets on OSN value development. This exploratory study mainly aims to propose and examine the individual–social–technology fit model through an empirical investigation. The main argument of the study is that when a positive and healthy virtual society is developed through social software, the individual and social characteristics, as well as the social software features, should be defined with a suitable fit to promote the social networking value.

Multi-Level Adaptation in End-User Development of 3D Virtual Chemistry Experiments

Multi-level adaptation in end-user development (EUD) is an effective way to enable non-technical end users such as educators to gradually introduce more functionality with increasing complexity to 3D virtual learning environments developed by themselves using EUD approaches. Parameterization, integration, and extension are three levels of adaptation ranging from straightforward to complex in terms of what end users have to understand in order to develop functional software applications, all within reach of end users without special training on programming. A 3D educational application EUD system prototype, iVirtualWorld, has been expanded to support 3D virtual chemistry experiments generation using these three levels of EUD adaptation. An evaluation has been conducted on 18 participants from the education domain, and the results confirmed ease-of-learn, ease-of-use, and usefulness of this solution. Contributions of this paper are 1) a paradigm for applying EUD technologies in 3D virtual learning environment creation; 2) an easy-to-use tool for educators to build customized virtual chemistry experiments; and 3) empirical assessment data for the multi-level adaptation solution.

IMPACT OF 3D GRAPHIC STRUCTURE COMPLEXITY TO THE RENDERING TIME

The paper presents new approach to the analysis of the time required for rendering, depending on the complexity of the 3D object. Ray tracing is used to measure program complexity measure parameter based on the rendering time. Parametric analysis using ray tracing program is achieved by correlation between image parameters and rendering time. Electronic imaging and image processing (rendering) are considered in the 3D virtual photorealistic imaging design and electronic imaging creation and optimization. We are attempting to treat the complexity as a measure in the process of creating and rendering a complex image. The work is directed towards defining and optimizing the rendering time in the photorealistic 3D image creation process. The correlation between large numbers of image components obtained by the ray tracing program is used to measure the scene complexity regarding of render time. To discover which space variable to use as complexity measure, we cross-correlated variables output by ray tracing program, keeping track of the maximum values. Based on this method, the highest correlation was observed on variable Bounding box succeeded tests, and that way obtained the complexity measure for the image. That way the original research is performed in creating analytical (data-visual) methods for determining the image rendering parameters. The results based on experimental verification on a large number of performed standard tests on real sets of graphical contents, and established the impact of graphical content complexity to the rendering time at distributed cluster computing systems.

Simulation Tools as an Educational and Training Resource in Manufacturing Engineering Subjects Teaching

Education & Learning Process at Manufacturing Engineering subjects requires the use, at every educational level, of resources and technologies that improve professor educative practice and student contents and competences acquisition. In this work it is showed the use of a 3D simulation tool for virtual models creation, carried out by National Distance University of Spain and the Salesianos Atocha School at Madrid, Spain, within the practical part of several subjects of their manufacture engineering studies and professional formative. It is analyzed and discussed the development of a virtual model that simulates a lathe gearbox manufacturing project in the classroom. A 3D CAD geometry is used as a base for the calculation and design of all the gearbox components (main spindle, chuck ́s joints, gears, change of feed, etc.). This methodology, used with every lathe component, permits the presentation of the machine as a whole and the analysis of the gearbox development in it. Human factors, assembly time, workplaces development and 3D lines design are studied and analyzed within the proposed model. The programs which have been used to develop this work are: Inventor 2009, Adobe Premier and 3D Studio Max R6. The final results can be displayed into several digital formats which help with the pedagogical model promotion.

VCDE: a toolkit for virtual cluster creation for grid environment

Virtualisation is a promising technology that has attracted much attention, particularly in the grid community. Recent advances using virtualisation technologies enable multiplexing the physical resources by means of virtual machines (VMs) resulting in better resource utilisation. We propose virtual cluster development environment (VCDE) to dynamically form virtual cluster on demand, providing the grid execution environment using VMs. The formation of a grid environment to execute any parallel or sequential application has been automated by VCDE. The user can simply submit the job along with the requirements of hardware and software needed for the execution. The VCDE provides easy access to the grid by reducing the burden of Globus toolkit installation and other configurations. It is important to note that there is no human intervention in the preparation of virtual cluster as well as the grid environment. The proposed VCDE uses virtualisation technologies, and it helps the user to make use of grid as easily as possible.

Training benefits of virtual bronchoscopy prior to Endobronchial Ultrasound Guide sheath

Research questions. How does a virtual bronchoscopy navigation system (VBNS) improve prediction of candidate bronchus across a range of doctors investigating a range of lesions with Endobronchial ultrasound (EBUS) guide sheath? To what extent do benefits of virtual bronchoscopic pre-procedure navigation apply to experienced versus inexperienced bron- choscopists? Methods: Using archived EBUS Guide sheath cases, a comparison was made between identified candidate 4th order bronchus by Computerised tomography (CT) evaluation versus that identified after virtual path creation. Results: From 7 archived cases, 14 doctors identified the correct bronchus in 94 of 98 assessments (95%). Percentage of cases where there was an improvement in localisation by 2 or more 4th order bronchi was 39.8% overall (28.6% – 51.0%), 26.6 for experienced and 53.1 for inexperienced bronchoscopists (p < 0.02). The absolute mean number of 4th order bronchi different between CT and VBNS was 2.0 ± 2.6 overall, 1.2 (range 0-6) for experienced, and 2.8 (range 0-11) for inexperienced bronchoscopists. Virtual Path software calculation time was 8.1 ± 2.7 minutes, compared to 3.6 ± 2.1 minutes by CT. Conclusion: VBNS allowed rapid accurate assessment with minimal software training. Greatest benefits in reduction of procedure time were obtained in inexperienced bronchoscopists, and VBNS could allow more rapid skill development in EBUS GS in these doctors.

Agreement negotiation support in virtual organisation creation–an illustrative case

In the actual market conditions, where it is essential to rapidly respond to business opportunities that might emerge, the concept of virtual organisation (VO) appears particularly well suited. The possibility of rapidly forming a VO to respond to a business or collaboration opportunity gives companies an expression of agility and survival mechanisms in the face of market turbulence. Nevertheless, in the process of VO creation, the negotiation among partners is essential. It is of extreme importance to have an environment where all potential partners can come together and negotiate the necessary topics towards an agreement to regulate the consortium behaviour. Through this environment it should be possible to conduct and manage the VO negotiation process, reach agreements and commitments among partners, enclose necessary documentation, specify partners’ rights and duties, etc. To accomplish such environment, a negotiation wizard is proposed. An illustrative scenario of an agreement negotiation in a multicultural context is presented showing the applicability of the wizard.

The impact of Product Lifecycle Management on virtual team creation: a concept change model for heightened productivity

This paper addresses issues related to the implementation of Product Lifecycle Management (PLM) in support of Cross-Cultural Virtual Teams (CCVTs). The CCVT Model presented in this paper will educate those currently involved in PLM operations as to: • How successful CCVT can be created • How PLM and CCVTs serve to strengthen and support each other. The methodology for creating the CCVTM was based on the Hofstede model and Project GLOBE research, and analysis of the current research on the virtual teams. Finally, these findings were combined so that cross-cultural factors are directly considered in the construction of virtual teams.

Stimulating community building using mobile 2.0 technology

Virtual or online content creation is no longer an external process done by software developers or professional new media players, but is more and more performed by ordinary people. In this paper, we focus on non-professional users to present how different categories of users get involved in the process of content sharing and creation within a city community. That only a few of them are interested in contributing to this community is nothing new in itself. Instead, we want to look at what is needed to encourage them to help us build up a virtual 'replica' of the city using an ad hoc application, i.e., the A4MC³-application. To support them in achieving this goal, this mobile city device must have some iterative elements (like tags, ratings, comments, etc., which are also known as social features) that stimulate users to become active members of that particular community. By exploring which of these interactive elements are most suitable on mobile devices, we hope to define a framework to support users in generating content in a user-friendly way.

Virtual Creation, Simulated Destruction, and Manufactured Memory at the Art Mecho Museum in Second Life

It is not your typical art museum. The buildings glass atrium is topped by a rotating tower built to resemble a giant nineteenth-century optical toy. The walls are made of translucent paper, and at night the building glows like a Japanese lantern. There is no roof. Patrons traversing the museums catwalks and balconies sometimes lose their balance and fall crashing to the galleries below. Other visitors descend from the sky on jetpacks and make soft landings in the museum courtyard. And we have not even begun to describe the patrons themselves, or the art (Figure 1). The museum is located in Second Life, a virtual online world in which hundreds of thousands of people each month log on from around the world and use avatars to interact with each other in a virtual, three-dimensional, user-built environment. Second Life (SL for short) bears some resemblance to massively multiplayer online video games like World ofWarcraft, and it includes some game-like activities, but its open-ended rule base and customizable environment (everything from avatar clothing and bodies to local gravity can be adjusted by users) makes it more adapted to social, commercial, and artistic activities. For example, it is host to an enthusiastic network of artists and exhibitors who make, buy, sell, and display virtual art and architecture.

High quality virtual view synthesis based on corrected surface mapping and image fusion

Perceptual errors introduced by current virtual view creation approaches for free viewpoint video often result in severe distortions in synthesised images. A novel virtual view synthesis algorithm is proposed based on corrected region based surface mapping and an image fusion method to reduce perceptual errors. The results over multi-view image sets imply that the proposed method improves the objective and subjective performance simultaneously, compared with previous dominant multiple image view synthesis approaches.

Support for virtual organisation creation &amp;ndash; partners' profiles and competency management

The only possibility for Small and Medium Enterprises (SMEs) to succeed in marketing competition with big corporations is cooperation and sharing of knowledge and resources. A promising way to cooperate and keep their independence is the formation of semipermanent collaborative networks, which facilitate Virtual Organisation (VO) creation and management. This work concentrates on the maintenance and facilitation of partners' profiles and competency management in such networks. The aim of our effort is to support potential partner identification during the VO creation and adaptation processes, as well as the facilitation of advertisement of oneself to be identified as a potential partner. The contributions of the work are the definition of competency and profile-related terms, the description of competency structures and an architecture of a competency and profiles management system, as well as a prototype verifying the presented theoretical work in a real business environment.

Presentation of the virtual Beyond-self on cyber stage: Real, constructed, staged and/or masked?

The main aim of the article is to enhance the realisation that cyberspace creates a different setting of virtuality where a virtual self is presented, thereby eliciting a notion that there was once either an ideal era of bliss or a Utopian promise of universal self-realisation. From a communicative perspective, it is propagated that virtual communities and knowledge creation as consequences of the accelerating rate of change and the subsequent cyber revolution emphasise the increasing importance of the virtual self, especially on cyber stage. Following a modifed categorical communicative imperative analysis with deliberative drawing on various philosophical and communicative paradigms from the premodernist through to the modernist and postmodernist eras, culminated in the ‘discovery’ of the theatrical virtual self. This the author subsequently labelled Beyond-self as a logical fow following Levinas's notion of the I (the self, the ego), the Other (which is diffcult to make sense of because it is a metaphysical face without an actual face) and the Third (the way you look at yourself in the eyes of the Other and ‘correcting’ the Other as a result). The main premises are based on the argument that a new formulation of the virtual self as the Beyond-self can be invoked in the cyber-beyond-modernist era, not only to facilitate social interaction among members, but more signifcantly to infuence the way in which members present the virtual self through the use of theatrical metaphors to the Other – whether this self is real, constructed, staged and/or masked.

The ORIGAMI Project: Advanced tools for creating and mixing real and virtual content in film and TV production

The goal of the EC-funded IST project ORIGAMI was the development of advanced tools and new production techniques for high-quality and seamless integration of real and virtual content in film and TV productions. In particular, the project focused on pre-production tools for automatic virtual set creation through image-based 3-D modelling of environments and objects. One key goal of the project was to achieve real-time in-studio pre-visualisation of the virtual elements (objects and actors) of the extended set. In this contribution the studio pre-visualisation system that has been developed for the project is illustrated, and its usage within a high-end film and TV production environment is described. Furthermore an overview of the developed solutions for automatic generation of 3-D models of environments, static objects and (moving) actors is given.

A treatise on order in engineering design research

Engineering design research shows a rather fragmented, if not a chaotic, picture. But does it have a hidden order? Can we explore it, or should we impose a reasoning model? This paper looks for the answer in the purpose of engineering design. It is destined to sustain human existence and well being by virtual creation of artifacts and services for the society. To this end, the engineering design discipline should provide a proper body of knowledge. The design knowledge obtained by empirical exploration and/or rational comprehension should be transformed for practical/pragmatic deployment. It was assumed that this purposely streaming of design knowledge gives a unique rationale for engineering design research. Based on this, a framework of reasoning was constructed, including source, channel, and sink categories of knowledge and research of engineering design, respectively. Within each category, research domains, trajectories, and approaches were identified. The semantic relationships of domains, trajectories, and approaches form a hierarchical structure. The proposed framework enables a grounded argumentation about the order of engineering design research, as well as about the articulation of the engineering design knowledge.
