The mixed record on the 2015 Millennium Development Goal (MDG) targets and the focus on global public goods in post-MDG debates questions the future of traditional development co-operation (official development assistance, ODA). Meanwhile, international financial crisis and fiscal retrenchment have focussed policy makers on the international dimensions of income and asset taxation. This paper e...

“When you make a prediction, would you rather be correct or incorrect? If your answer is'correct,' then ODA [optimal data analysis] is the appropriate analytic methodology...” (p. xi). With this audacious, provocative opening statement, Paul Yarnold and Robert Soltysik set the stage for a revolutionary paradigm shift in statistical analysis. It is obvious that no one could rationally answer “no...
This research examines the strategic conditions that drive entrepreneurial innovators to pursue novel innovation, rather than innovation that is closer to existing technologies. Since radical breakthrough innovation is harder to communicate than incremental counterpart, entrepreneurial innovators may be steered away from breakthrough innovation where the cost of developing credible information ...
in this paper, we prove the existence of the solution for boundary value prob-lem(bvp) of fractional dierential equations of order q 2 (2; 3]. the kras-noselskii's xed point theorem is applied to establish the results. in addition,we give an detailed example to demonstrate the main result.
the purpose of this letter is to revisit the nonlinear reaction-diusion modelin porous catalysts when reaction term is fractional function of the concen-tration distribution of the reactant. this model, which originates also in uidand solute transport in soft tissues and microvessels, has been recently givenanalytical solution in terms of taylors series for dierent family of reactionterms. we...
in this work, we conduct a comparative study among the combine laplace transform and modied adomian decomposition method (lmadm) and two traditional methods for an analytic and approximate treatment of special type of nonlinear volterra integro-differential equations of the second kind. the nonlinear part of integro-differential is approximated by adomian polynomials, and the equation is red...
in this study, a new and ecient approach is presented for numerical solution offredholm integro-dierential equations (fides) of the second kind on unbounded domainwith degenerate kernel based on operational matrices with respect to generalized laguerrepolynomials(glps). properties of these polynomials and operational matrices of integration,dierentiation are introduced and are ultilized to r...
اثر روش lsp بر روی خاصیت عبوری نمونه تهیه شده ، توسط طیف سنجی uv-vis-ir در محدوده ی طول موجی 1200-400نانومتر قبل و بعد از روشlspانجام پذیرفت.برای بررسی اثرات بر روی سطح ، قبل و بعد از اعمال روشlsp از سطح آن، تصویر sem گرفته شد.برای بررسی اثر روش lsp بر روی آستانه تخریب، نمونه تحت آزمون آستانه تخریب قرار گرفت. کیفیت آزمون آستانه تخریب در دو حالت برای نمونه در نظر گرفته شد.حالت اول ،نمونه با لای...
Polybutadiene acrylic acid acrylonitrile (PBAN) is binder for composite solid propellants used in spacecraft systems which its curing kinetics is so important. In this research, the effect of functionality of epoxy curative on the curing kinetics of PBAN is researched. Equivalent stoichiometric ratios of PBAN and di-functional (DER 331) and tri-functional (LY 5052) epoxy curatives was cured at ...
