Provincial Linkage Characteristics of Hog Price in China Based on Linkage Social Network Analysis Method

In order to obtain the visual data of linkage structure and network characteristics of hog price among provinces in China, an improved analysis method of social network correlation was proposed in this article. The lift of association rules were introduced to analyze the correlation of hog prices in different provinces in China and taken as the weight matrix of network analysis. Besides, based on social network analysis parameters and UCINET visualization technology, network analysis was carried out on the linkage relation and linkage characteristics. The application results show that, the lift of association rules can quantitatively and precisely obtain the correlation and differences of tendency of hog price, and the established network structure and parameters can visually and quantitatively present the linkage characteristics of hog price among regions and provinces.

Basic Kirkwood – Buff Theory of Solution Structure and Appropriate Application of Wyman Linkage Equation to Biochemical Phenomena

Background: Researchers who have shown interest in the consequence of introducing dry biomolecules or a solution of it into cosolvents generally known as osmolyte, have applied many models for the elucidation of the scientific basis of the results obtained. The Kirkwood and Buff theory (KBT) or its reverse form has been the basis for the interpretation of the effect of the osmolyte. There seems to be no generally acceptable definition of terms in the basic KBT mathematical formalism. There is also error in stated equations describing solution structure and misapplication of Wyman linkage relation. Therefore, the objectives of this research are 1) to show how the equation of preferential interaction parameter is derived based on KBT, 2) to show the appropriate way in which Wyman linkage relation can be applied, 3) to apply biochemical approach (using generated data) to the equation of preferential interaction parameter (preferential interaction parameter is symbolised as ) for its calculation and calculation of parameters linked to KBT derived equations. Methods: The research is mainly theoretical and partly experimental. The experiment entails Bernfeld method of enzyme assay for the generation of data. Results and Discussion: The change in solvation preference upon the ethanol partial denaturation of the enzyme and the corresponding change in preferential interaction parameter were respectively positive and negative in sign. Unexpectedly ethanol was preferentially excluded from the enzyme. Conclusion: The equations of preferential interaction parameters were derived. The appropriate way is either by calculation or measurement of preferential interaction parameter. Therefore, or for the change, cannot be a constant (or slope) and an instrumentation–based measurable parameter at the same time. Based on Wyman linkage relation, purely biochemical thermodynamic parameter is linked to preferential interaction parameters which are therefore, thermodynamic parameters.

Stock Market Liquidity Measurement via the Bid-Ask Spread: Tunis Stockmarket

In this paper, we attempt to explore the nature of the linkage relation of liquidity with market structure. Owing to his function of serving liquidity immediacy, the market maker determines his transacting prices (bid and ask) with all other operators. Accordingly, via his bid-ask spread, he does orient the transaction flow. This study shuts for testing a measure of market liquidity via the bid-ask spread via Stoll Model methodology (1989) on the covariance s’ regressions on Tunis stock market over a period stretching from January 2005 until January 2012. The results show that the higher the spread; the less liquid is the market.

Η Ακεραιότητα στην Ερευνητική Πρακτική σε Ευρώπη και Ελλάδα

Research integrity is an essential and integral part of scientific research ethics. It is commonly accepted that the value of scientific research vitally depends on the fulfillment of research integrity codes of conduct. The unbreakable linkage (relation) between research value and research integrity does not reflect only its attachment to the application of proper scientific method but also its acceptance from the society. In this work we present a survey on the organization of the institutions of research integrity in international, European and national level. Emphasis is given in the description of the present state in Greece in the level of Higher Educational Institutes, Research Centers and Committees. Also, we focus on the actions taken from National Technical University of Athens, as well as the initiative from EARTHnet network and their efforts for institutionalization of a common code of conduct in scientific research at a national level.

LINKAGE RELATION OF RESISTANCE TO CLADOSPORIUM LEAF MOLD (Cf-2) AND ROOT-KNOT NEMATODES (Mi) IN TOMATO AND A NEW GENE FOR LEAF MOLD RESISTANCE (Cf-11)

Mi derived from Anahu and Cf-2 derived from Indian River are approximately at locations 35 and 43 on the long arm of chromosome 6 of the tomato (Lycopersicon esculentum Mill.). Ontario 7716 contains the leaf mold resistance gene Cf-11 which was derived from an aberrant plant of Mass. #2. Both Cf-2 and Cf-11 confer immunity from Cladosporium fulvum Cke. races 1 and 10. Cf-11 confers high resistance to race 6 and slight tolerance to race 12 whereas Cf-2 does not confer any resistance to these races of C. fulvum.
