THE NIGERIAN OIL RESOURCEAND SOVEREIGN WEALTH FUND: AN INTERROGATION by Joshua DANJUMA

“…The paper adopts content analysis of mainly secondary sources to examine the research problem at stake using the resource curse theory. Findings reveal poor political institutions, corruption and lack of accountability, weak executive control of oil resource governance with apparent inadequate checks and balances, and the resultant conflicts and clashes of interests, manipulations, and inflation of oil contracts with favouritism in allocating oil blocs to cronies.Therefore, this articleshades in a newlight by interrogating the Nigerian Sovereign Wealth Fund to ensure optimal benefits of oil wealth to all citizenry; it submits that measures must be adopted in building political institutions, reforming the Niger Delta Development Commission; diversification, building a welfare state, equitable distribution of oil wealth and the imposition of direct tax. …”

Positive Solutions for Second-Order Singular Semipositone Differential Equations Involving Stieltjes Integral Conditions by Jiqiang Jiang, Lishan Liu, Yonghong Wu

“…By means of the fixed point theory in cones, we investigate the existence of positive solutions for the following second-order singular differential equations with a negatively perturbed term: −u′′(t)=λ[f(t,u(t))−q(t)], 0<t<1, αu(0)−βu′(0)=∫01u(s)dξ(s), γu(1)+δu′(1)=∫01u(s)dη(s), where λ>0 is a parameter; f:(0,1)×(0,∞)→[0,∞) is continuous; f(t,x) may be singular at t=0, t=1, and x=0, and the perturbed term q:(0,1)→[0,+∞) is Lebesgue integrable and may have finitely many singularities in (0,1), which implies that the nonlinear term may change sign.…”

Nonlinear Disturbance Observer-Based Adaptive Sliding Mode Control for a Generic Hypersonic Vehicle by Jianguo Guo, Hao Zhang, Xiaodong Lu, Jun Zhou

“…Thirdly, a set of nonlinear disturbance observers are designed to estimate the lumped disturbance and compensate the sliding mode controller, and the stability of the proposed controller is analyzed by utilizing Lyapunov stability theory. Finally, simulation results show that the effectiveness of the proposed controller is validated by the nonlinear model and the proposed method exhibits promising robustness to mismatched uncertainties.…”

Taking offense: Religion, art and visual culture in plural configurations, by Christiane Kruse, Birgit Meyer, and Anne-Marie Korte (eds.) 2018 by Tammy Wilks

“…The question is central to the expanding study of material religion - the theory that things, like images, have agency because they are 'caught up', as Ingold (2007:1) states, in the currents of our life worlds and epistemologies (cf. …”

ITG 1000, Risk Detection and Accounting Information: a Theoretical Analysis on the Cost versus Benefit for Micro and Small Enterprises by Mateus Alexandre Costa dos Santos, Luiz Carlos Marques dos Anjos, Paulo Roberto Nóbrega Cavalcante, Paulo Aguiar do Monte

“…In addition, it was guided by the classical model proposed by Allingham and Sandmo (1972), referring to the economic theory of tax evasion. It may be noted that the successful adoption of ITG 1000 can be achieved with an awareness of the segments involved and with the prohibition and penalizing of adverse behavior, permitting one to infer that the adoption of the 1000 ITG is much more dependent on the accounting class’s actions, rather than a management decision itself.…”

Wake Behavior behind Turbine Cascades in Compressible Two-Dimensional Flows by Rainer Kurz

“…Data from experiments with turbine cascades in compressible flow will be used to derive a theoretical approach which describes the wake growth and the recovery of the velocity deficit. The theory is based on similarity assumptions. The derived equations depend on simple and readily available parameters such as overall losses, exit angle, and Mach or Laval number. …”
