in this paper, we analysis the concept and importance of property rights in classical and institutional economic thought schools. in doing so, we analysis the thoughts of luck, adam smith, say, ricardo, malthus, mill, marx, engels, marshal (some classical economists), coase, demsetz, north, and dosoto (some new institutional economists). the results of the paper revealed that: 1) classical econ...

the research entitled “a comparative study of saadi’s golestan and samuel johnson’s rasselas” is based on the inclination of 18th century writer and theorist johnson on towards rich persian literature and outstanding resemblance of golestan and rassales from the structural, moral, philosophical points of view. the findings are based on two hypotheses: (1) has there been any basis for johnson’...

In the present study, the full-length nucleotide sequences of the CSFV-GZ-2009 strain of classical swine fever virus (CSFV) isolated from a hog pen in Guangdong province in China was determined. Results demonstrated that the genome of CSFV-GZ-2009 is 12,298 nucleotides (nt) in length, is composed of a 373-nt 5'-untranslated region (UTR), has an 11,697-nt open reading frame encoding a polyprotei...

Two regulators of hair-cell patterning in Arabidopsis act in the cells where they are produced to inhibit primary cell fate in neighboring cells. Their relationship to the activators of the primary cell fate suggests a classical activator-inhibitor model for patterning that can now be analyzed in detail.

Population trends, defined as interval-specific proportional changes in population size, are often used to help identify species of conservation interest. Efficient modeling of such trends depends on the consideration of the correlation of population changes with key spatial and environmental covariates. This can provide insights into causal mechanisms and allow spatially explicit summaries at ...

BACKGROUND If presentation of a stimulus (conditional stimulus, CS) reliably predicts delivery of a reward, the CS will come to evoke a conditional response (CR) through Pavlovian learning, and the CS may also acquire incentive motivational properties. Thus, CSs can have both predictive and incentive properties. We ask here whether it is possible to dissociate the predictive versus incentive pr...

Motivated by the recent work of Louko and Molgado, we consider the Ashtekar-Horowitz-Boulware model using the projection operator formalism. This paper uses the techniques developed in a recent paper of Klauder and Little to overcome the potential difficulties of this particular model. We also extend the model by including a larger class of functions than previously considered and evaluate the ...
