Industrial Cluster, Similarity, and External Economies

This paper develops a simple model in which external economies are caused by interconnectedness among firms in intracluster and intercluster. Two main results are developed. First, the larger the elasticity of substitution between any two products produced within the cluster, the larger the cluster’s output; second, a cluster with larger elasticity of substitution yields larger output among different clusters other things being equal

Boys and girls: Chinese future teachers\u27 expectations

The current study examines the expectations of Chinese education majors for their future students in the areas of academic behavior, classroom behavior, academic performance, and general behavior. Of special interest to us was the question whether the future teachers would have very similar or different expectations for boys and girls. A group of 152 education majors at a medium-sized university in Shanghai participated in the study by filling out a survey questionnaire. The results indicate that both male and female education majors had similar expectations of their future students in the areas of academic behavior, classroom behavior, and general behavior; however, they differed significantly on the Academic Performance Scale

La protección social y jurídica de menores en situación de riesgo o desamparo en la Comunidad Valenciana

[ES] El trabajo se centrará en el régimen legal de protección social y jurídica de menores en riesgo o desamparados en el ámbito de la Comunidad Valenciana. Se partirá de los principios y políticas rectores generales de actuación en esta materia, a nivel de prevención y de asistencia. Seguidamente se abordará el análisis de las situaciones problemáticas de los menores (riesgo, desamparo...), para concluir con el régimen de funcionamiento de las instituciones de protección de menores desamparados (tutela, guarda y acogimiento).[EN] The work will focus on the legal regime of social and legal protection of minors at risk or homeless in Valencian Community. It will start from the principles and general policies of action in this matter, at the level of prevention and assistance. The analysis of problematic situations of children (risk, helplessness, etc.) will be followed, in order to conclude with the functioning of institutions for the protection of homeless children (guardianship, custody and placement).Zhan, Q.

Multi-level Monte Carlo methods with the truncated Euler-Maruyama scheme for stochastic differential equations

The truncated Euler-Maruyama method is employed together with the Multi-level Monte Carlo method to approximate expectations of some functions of solutions to stochastic differential equations (SDEs). The convergence rate and the computational cost of the approximations are proved, when the coefficients of SDEs satisfy the local Lipschitz and Khasminskii-type conditions. Numerical examples are provided to demonstrate the theoretical results
