东西方文化差异对当代大学生自尊水平的影响——基于上海某民办大学学生的问卷调查

自尊是个体对自己作为一个人的价值进行的主观评价。自尊水平高的人在学业、工作和人际交往中往往能够获得成功。反之,自尊水平低会导致心理健康问题。国内针对大学生的自尊研究主要有两类,不同学生群体的自尊水平调查以及其他变量与自尊水平的关系。随着全球化速度的加快,21世纪的大学生在东西方文化的对持和交融中,自尊水平是否受到影响是本研究的重点。本研究的被调查者来自上海市某民办高校,包括从大学一年级到四年级共546名学生。研究发现,所有被试者在西方文化的认同上稍高,但东西方文化对他们自尊水平的影响无显著差异。

Optimal Port Design Minimizing Standing Waves with A Posteriori Long Term Shoreline Sustainability Analysis

Optimization theory is applied to a coastal engineering problem that is the design of a port.This approach was applied to the redesign of La Turballe Port in order to increase the exploitable surface area and simultaneously reduce the occurrence of long waves within the port.Having defined the cost function as a weighted function of wave amplitude and with the chosen parameterization of the port,results show that an extended jetty and a widened mole yield a unique optimal solution.This work demonstrates that numerical optimization may be quick and efficient in the identification of port solutions consistent with classic engineering even in the context of complex problems.
