Economic Anthropology, EarlyView.ABSTRACT In the Chinese kimchi industry, manufacturers employ product names, photographs, and logistical strategies to promote their kimchi's “Koreanness.” So, what makes their kimchi “Korean,” and how does its Koreanness formulate kimchi's commodity value?

A minimax formula for the principal eigenvalues of Dirichlet problems and its applications
Electronic Journal of Differential Equations, 2007 A minimax formula for the principal eigenvalue of a nonselfadjoint Dirichlet problem was established in [8,18]. In this paper we generalize this formula to the case where an indefinite weight is present.

Strongly indefinite systems with critical sobolev exponents and weights
Applied Mathematics Letters, 2004 Let \(\Omega\) be a bounded smooth domain in \(\mathbb R^N\), \(N\geq 4\) and \(\lambda,\mu\in\mathbb R\). The author deals with the following problem: \[ -\Delta v=\lambda u+K(x)|u|^{p-1}u\text{ in }\Omega, \quad -\Delta u=\mu v+ Q(x)|v|^{q-1}v\text{ in }\Omega, \quad u=v=0\text{ on }\partial\Omega, \tag{1} \] where \(p,q>1\) and coefficients \(K,Q ...

Homicide, punishment and deterrence in Australia
Southern Economic Journal, EarlyView.Abstract Australian data encompassing 1910–2022, by year and state, were analyzed to estimate the effect of capital punishment on homicide rates. Our estimates showed that capital punishment had a negative and significant effect on homicides. In some specifications, the estimates implied that an execution was associated with 12.68 fewer homicides ...

A Discontinuous Sturm-Liouville Operator With Indefinite Weight
Journal of Mathematics Research, 2010 In this paper, we consider an indefinite Sturm-Liouville operator with eigenparameter-dependent boundary conditions andtransmission conditions. In an appropriate space K, we define a new self-adjoint operator A such that the eigenvalues ofA coincide with those of such a problem and obtain asymptotic approximation for its eigenvalues and eigenfunctions.

Living With Chronic Rhinosinusitis: Insights From an Arts‐Based Study
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Background Chronic rhinosinusitis (CRS) significantly reduces quality of life (QoL), but data regarding the extent of its impact is sparse. Questionnaire‐based assessments of QoL may neglect aspects of complex patient experiences. Recent studies on asthma patients and other chronic conditions have used self‐expression through artwork to better

Schrödinger equations with indefinite weights in the whole space
Comptes Rendus. Mathématique, 2009 We consider in this Note equations defined in RN involving Schrödinger operators with indefinite weight functions and with potentials which tend to infinity at infinity. We give some results for the existence of principal eigenvalues and for the maximum principle. We also obtain Courant–Fischer formulas for such eigenvalues.

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.
