Expenditure Patterns Of Households Receiving Remittances In Thailand, Sha Ma
Chulalongkorn University Theses and Dissertations (Chula ETD)
This article, through the data of the Statistics Bureau of Thailand in 2007 and 2015, examines whether remittances brought about by economic migration will affect household expenditure patterns. This study includes three expenditure patterns: education expenditure, housing expenditure, food and beverage expenditure. The result shows remittances have no effect on housing expenditures. Families receiving remittances, the non-poor households pay more on education than the poor households. And poor households always have more expenditure on food and beverage than non-poor households.
Statelessness And Human Rights, I Hsuan Liu
Statelessness And Human Rights, I Hsuan Liu
Chulalongkorn University Theses and Dissertations (Chula ETD)
Although the Universal Declaration of Human Rights has expressed that human rights are guaranteed to everyone, however, the reality is that millions of people still remain stateless and their human rights are denied. Under the 1954 Convention relating to the Status of Stateless Persons, the Contracting States have attempted to guarantee quasi-national and quasi-alien status to the rights of the stateless persons. However, many of these rights have not adequately specified or in lacking an affirmative protective mechanism. This leads to the re-examination of the human rights that are developed after the 1954 Convention relating to the Status of the …

Critical Exponent For Nonlinear Nonlocal Equations, Auttawich Manui
Chulalongkorn University Theses and Dissertations (Chula ETD)
In this thesis, we study the nonlinear nonlocal equation ∂t u=J*u-u+u¹+p where p>0 and J is nonnegative, bounded, and radially symmetric with unit integral. The Fourier transform of J satisfies J ̂(ξ)=1-A|ξ|^β (ln1/|ξ| 〗 )^μ+o(〖|ξ|〗^β (ln〖1/(|ξ|)〗 )^μ ) as ξ→0, for 0<β≤2, μ∈R, and A>0. In this study, we establish the local existence, uniqueness, and the comparison principle of solutions. Furthermore, we show that the Fujita critical exponent for this equation is β/n when μ<0. For the case μ>1, we discover that the critical exponent is β/n , and the solutions belong to the global to the small initial data regime.
