Immigrant Assimilation and Charitable Giving

Economic research about charitable giving among immigrant populations in the United States sheds light on charitable behaviors related to, but not often included in, discussions of black philanthropy. This paper examines immigrant assimilation in charitable giving

An Analysis on Syntactic Derivation of “Patient + Agent + Ergative Verb”

“Patient + Agent + Ergative verb”, in fact, it is a kind of absolutive structure, in which word order and case marking contribute to its formation. It assumes that “Patient + Ergative verb” is the basis syntactic structure, which generates “Patient + Agent + Ergative verb”. And it verifies the hypothesis by checking of light verbs, the characteristics of split-ergativity and Case Hierarchy

Complex System Optimization using Biogeography-Based Optimization

Complex systems are frequently found in modern industry. But with their multisubsystems, multiobjectives, and multiconstraints, the optimization of complex systems is extremely hard. In this paper, a new algorithm adapted from biogeography-based optimization (BBO) is introduced for complex system optimization. BBO/Complex is the combination of BBO with a multiobjective ranking system, an innovative migration approach, and effective diversity control. Based on comparisons with three complex system optimization algorithms (multidisciplinary feasible (MDF), individual discipline feasible (IDF), and collaborative optimization (CO)) on four real-world benchmark problems, BBO/Complex demonstrates competitive performance. BBO/Complex provides the best performance in three of the benchmark problems and the second best in the fourth problem

Immigrant Assimilation and Charitable Giving

Will immigration impact economic progress and social cohesion in host countries? One indicator that can shed new light on the complex process of immigrant assimilation is charitable giving. Charitable giving and other forms of civic engagement may affect norms of trust, connectedness, and cooperative behavior. We find that immigrant status has a negative, but insignificant impact on the incidence and levels of charitable giving. There is considerable evidence that immigrants adapt rapidly to U.S. charitable institutions over time. Results on private transfers present a striking contrast. Immigrant households are significantly more likely to participate in private transfer networks

A Study of Gurnah’s Memory Narrative and Diaspora Identity

The Nobel Prize for Literature has been won by 70-year-old Tanzanian novelist Abdulrazak Gurnah for “his uncompromising and compassionate penetration of the effects of colonialism and the fate of the refugees in the gulf between cultures and continents”. “Refugees” highlights the issue of identity, while the transferring of cultural continent highlights diaspora, and memory narrative is a characteristic of his writing, which can be adopted to explore the symptoms of identity exfoliation and diaspora. This paper, by focusing on the theories of memory and diaspora identity from the perspective of Gurnah’s memory narrative, aims to explore the racial identity, focusing on the antagonism and hatred between races in the post-colonial context, the hybrid identity in the context of family diaspora, the social identity in the context of group culture, and the female identity in the development of individuality.Memory is an important texture that underlines Gurnah’s writing and his perception and deep thinking on identity provides a multidimensional entry point for the international literary world with unique personal characteristics and humanistic care in the global context. Racial identity, focusing on the antagonism and hatred between races; hybrid identity, the impotence of immigrants, unable to establish their own identity; social identity, the alienation of marginalized people and the young generation’s powerless sense of colonial culture; female identity, women’s weightlessness under gender pressure

The primitive equations with magnetic field approximation of the 3D MHD equations

In our earlier work \cite{DLL}, we have shown the global well-posedness of strong solutions to the three-dimensional primitive equations with the magnetic field (PEM) on a thin domain. The heart of this paper is to provide a rigorous justification of the derivation of the PEM as the small aspect ratio limit of the incompressible three-dimensional scaled magnetohydrodynamics (SMHD) equations in the anisotropic horizontal viscosity and magnetic field regime. For the case of $H^1$-initial data case, we prove that global Leray-Hopf weak solutions of the three-dimensional SMHD equation strongly converge to the global strong solutions of the PEM. In the $H^2$-initial data case, the strong solution of the SMHD can be extended to be a global one for small \v. As a consequence, we observe that the global strong solutions of the SMHD strong converge to the global strong solutions of the PEM. As a byproduct, the convergence rate is of the same order as the aspect ratio parameter.Comment: arXiv admin note: text overlap with arXiv:2206.06005; text overlap with arXiv:1706.08885 by other author
