The accuracy of parameters determined with the core-sampling method: application to Voronoi tessellations

The large-scale matter distribution represents a complex network of structure elements such as voids, clusters, filaments, and sheets. This network is spanned by a point distribution. The global properties of the point process can be measured by different statistical methods, which, however, do not describe directly the structure elements. The morphology of structure elements is an important property of the point distribution. Here we apply the core-sampling method to various Voronoi tessellations. Using the core-sampling method we identify one- and two-dimensional structure elements (filaments and sheets) in these Voronoi tessellations and reconstruct their mean separation along random straight lines. We compare the results of the core-sampling method with the a priori known structure elements of the Voronoi tessellations under consideration and find good agreement between the expected and found structure parameters, even in the presence of substantial noise. We conclude that the core-sampling method is a potentially powerful tool to investigate the distribution of such structure elements like filaments and walls of galaxies.Comment: 14 pages (Latex) with 6 figures, the complete paper with 8 figures is available at http://kosmos.aip.de/~got/projects.html {Characteristical scales in point distributions}, Astronomy and Astrophysics Supplement Series, accepte

INTERNAL ENVIRONMENT ANALYSIS TECHNIQUES

Theme The situation analysis, as a separate component of the strategic planning, involves collecting and analysing relevant types of information on the components of the marketing environment and their evolution on the one hand and also on the organizationâ€(tm)s resources and capabilities on the other. Objectives of the Research The main purpose of the study of the analysis techniques of the internal environment is to provide insight on those aspects that are of strategic importance to the organization. Literature Review The marketing environment consists of two distinct components, the internal environment that is made from specific variables within the organization and the external environment that is made from variables external to the organization. Although analysing the external environment is essential for corporate success, it is not enough unless it is backed by a detailed analysis of the internal environment of the organization. The internal environment includes all elements that are endogenous to the organization, which are influenced to a great extent and totally controlled by it. The study of the internal environment must answer all resource related questions, solve all resource management issues and represents the first step in drawing up the marketing strategy. Research Methodology The present paper accomplished a documentary study of the main techniques used for the analysis of the internal environment. Results The special literature emphasizes that the differences in performance from one organization to another is primarily dependant not on the differences between the fields of activity, but especially on the differences between the resources and capabilities and the ways these are capitalized on. The main methods of analysing the internal environment addressed in this paper are: the analysis of the organizational resources, the performance analysis, the value chain analysis and the functional analysis. Implications Basically such an analysis of the internal environment allows the organization to identify its resources and capabilities as best as possible, in relation to the threats and opportunities brought about by the crisis situations. Authors(tm) Contribution The research allows the identification of the organizational behaviour of resource and capabilities capitalization that must be adopted during the economic crisis. The study may be useful to both the academic and the business environment.marketing environment, internal environment, resource analysis, performance analysis, value chain analysis

STRATEGICALLY REPOSITIONING RUSSIA

Positioning is a very important marketing concept. Its importance was strongly emphasized and implemented in the case of companies, but is somehow neglected when it comes to states. A country acquires a position in the mind of a person very much like any other product does, which is very important especially when that person exerts an executive role. Nowadays Russia has a poor image or no image at all, both internationally and in Romania. In order to regain an important position in the Balkans region, Russia must set aside any political agenda and reposition itself as a business partner on equal terms. The first goal of this article is to clarify Russia's position in the minds of future Romanian executives. The second goal is to outline a recommended course of actions for Russia's repositioning.marketing, positioning, strategy, Russia, marketing research

Biomarkers in Traumatic Spinal Cord Injury

Spinal cord injury (SCI) is one of the most devastating traumas for an individual because the complete traumatic spinal cord injury leads to paraplegia or tetraplegia. The mechanical injuries directly cause axonal destruction in fiber tracts, destruction of the neurons, and of the glial cells, and their destruction releases substances whose presence, quantity, and dynamics can be lesional biomarkers. The reactions of partially injured cells simultaneously start and the occurring substances and their quantity may be reaction biomarkers. The lesional biomarkers appear immediately post injury and after several hours there are both lesional biomarkers and reaction biomarkers
