Unpacking China's Digital Ascent in the Global South: The Case of Huawei in North Africa

Global Policy, EarlyView.
ABSTRACT Despite frequent concerns in Western policy and media circles about the risks of using Chinese telecommunications suppliers, firms like Huawei have encountered little resistance from governments or citizens in the Global South. Empirical research explaining this acceptance remains limited.

Eigencurves of the p-Laplacian with weights and their asymptotic behavior

Electronic Journal of Differential Equations, 2007
In this paper we study the existence of the eigencurves of the p-Laplacian with indefinite weights. We obtain also their variational formulations and asymptotic behavior.

Positive radial solutions of n-dimensional elliptic systems with indefinite weight functions and n parameters

Advances in Difference Equations, 2019
Under simple conditions on f and a, we show the existence of positive radial solutions for the n-dimensional elliptic differential system {Δu(x)+Λa(|x|)f(u(x))=0,R10,x∈Rn,n≥2 $\mathbf{x}=(x_{1},x_{2},\ldots ,x_{n})^{T}, \mathbf{u}(\mathbf {x})=(u _{1 ...

Indefinite weight nonlinear problems with Neumann boundary conditions

Journal of Mathematical Analysis and Applications, 2017
The paper concerns the existence of multiple positive solutions to the second-order differential equation \[ u''+a(t)g(u)=0 \] posed on the bounded interval \([0,T]\) and associated with Neumann boundary conditions \(u'(0)=u'(T)=0\). The function \(g\) is such that \(g(0)=0\) and \(g(s)>0\) for positive \(s\) while the coefficient \(a\) has indefinite ...

South Africa: The Ambiguities of a Middle Power

Global Policy, EarlyView.
ABSTRACT South Africa represents an interesting species of a middle power. This derives from its inherited economic muscle as Africa's powerhouse and the liberation struggle against apartheid, both of which have shaped its democratic transition. The traditions of liberation and democracy, in turn, have profoundly influenced how South Africa has ...

Measuring the time‐varying market efficiency in the prewar and wartime Japanese stock market, 1924–1943

Asia‐Pacific Economic History Review, Volume 65, Issue 1, Page 131-159, March 2025.
Abstract This study examines the adaptive market hypothesis in the prewar and wartime Japanese stock market using a new market capitalization‐weighted price index. First, we find that the degree of market efficiency varies over time and with major historical events. This implies that the hypothesis is supported in this market.

Boundedness and monotonicity of principal eigenvalues for boundary value problems with indefinite weight functions

International Journal of Mathematics and Mathematical Sciences, 2002
We study the principal eigenvalues (i.e., eigenvalues corresponding to positive eigenfunctions) for the boundary value problem: −Δu(x)=λg(x)u(x), x∈D;(∂u/∂n)(x)+αu(x)=0, x∈∂D, where Δ is the standard Laplace operator, D is a bounded domain with smooth ...

When First Nations Don't Count: H.V. Evatt and the Erasure of Palestinian Rights

Australian Journal of Politics &History, EarlyView.
As Minister for External Affairs in the Chifley Government, Herbert Vere Evatt played a pivotal role at the United Nations in securing the partition of Palestine and recognition of the State of Israel. These endeavours were represented by Evatt and in subsequent commentary as exemplifying Evatt's commitment to justice.

Infinite semipositone problems with indefinite weight and asymptotically linear growth forcing-terms

Electronic Journal of Differential Equations, 2013
In this work, we study the existence of positive solutions to the singular problem $$displaylines{ -Delta_{p}u = lambda m(x)f(u)-u^{-alpha} quad hbox{in }Omega,cr u = 0 quad hbox{on }partial Omega, }$$ where $lambda$ is positive parameter, $Omega $

Self‐Giving and Reflections on Life Extension: How Love Might Shape the Choice of Whether to Live Past a Natural Human Lifespan

Bioethics, EarlyView.
ABSTRACT Drawing upon a deprivationist account of the badness of death, Ingemar Patrick Linden advocates for a hypothetical state called “contingent immortality.” The future Linden champions is one in which every person would be able to live for as long as they would like, save for events like accidents or murder.
