This paper presents a counterfactual decomposition of the public–private gap on test scores obtained by 8th graders in Brazil. Quantile regression methods are used to obtain a characterization of the conditional distribution of scores...

In 1990 Brualdi and Liu (J. Graph Theory 14 (1990) 483) introduced the concept of generalized exponent for primitive Boolean matrices. In the study of generalized exponents, we focus on problems of the following three types: (1) To dete...

In order to pay tribute in the special issue of Spectrochimica Acta Part B for Professor J.D. winefordner, this author looked back at the most exciting era of spectrochemical analysis, which started in 1955, during which atomic absorpti...

Let G=〈 x,y,t: x2=yk=t2=(xt)2=(yt2=1〉 and q be a prime Cheap Bailey Button Uggs power. Then any homomorphism from G into PGL(2,q) induces an action on the projective line over Fq. Such an action can be depicted by a coset diagram. W...

Let G be a non-bipartite strongly regular graph on n vertices of valency k. We prove that if G has a distance-regular antipodal cover of diameter 4, then k ≤  2(n +  1) / 5, unless G is the complement of ...

The modelling, analysis and design of beam joints are important in the study of control and stabilization of modern Ugg Boots Cheap Uk Sale large flexible space structures. In this paper we first briefly summarize our recent findings in...

The shape variation Ugg Sale Uk Boots displayed by a class of objects can be represented as probability density function, allowing us to determine plausible and implausible examples of the class. Given a training set of example shapes w...

Pure electronic Raman spectra with no phonon structures superimposed to the electronic continuum, Buy Replica Ugg Boots Uk are reported, in optimally Replica Uggs doped HgBa2CaCu2O6+δ single crystals (Tc=126K). As a consequence, the sp...

The legal versus ethical rights of behavioral health patients have long complicated inpatient treatment plans and Real Ugg Boots Uk Sale challenged the creative thinking skills of behavioral health nurses. This article examines the prac...

In a “closed-economy” cost-benefit analysis of a public investment, all affected economic agents matter. In such an analysis, if price equals marginal cost Cheap Uggs Australia in all affected markets, accurately measuring benefits ...
