关于布摩待遇的调查研究——以纳雍县新房彝族苗族乡的个案调查为例

布摩在彝族社会中曾一度享有崇高的地位,他们创造了彝族文字,传承了彝族文化,为人类的文明史书写了光辉的一页。然而,随着社会的变迁,科学技术的极速发展,布摩的生存空间越来越小。为此,我们当发挥布摩的特长,重新树立布摩在传承彝族文化中的地位,从而促进彝族文化健康持续发展。     

The effects of tuition fees on transition from high school to university in Germany

This paper studies whether the introduction of tuition fees at public universities in some German states had a negative effect on enrollment, i.e., on the transition of high school graduates to public universities in Germany. In contrast to recent studies, we do not find a significant effect on aggregate enrollment rates. Our study differs from previous studies in three important ways. First, we take full account of the fact that tuition fees were both introduced and abolished in the German states at different points in time. Second, we consider control variables, which are absent in previous studies but turn out to have a significant impact on the evolution of enrollment rates. Third, we allow for state-specific effects of tuition fees on enrollment rates. We conclude that there is no evidence for a general negative effect of the recent introduction of tuition fees on enrollment in Germany.

电子设备抗雷电电磁脉冲的干扰与接地

雷电电磁脉冲是一种携带巨大雷电能量的电磁脉冲干扰信号,对现代电子设备造成的危害极大。通过比较,电子设备对雷电电磁脉冲的防护虽然有别于直击雷,但将电磁脉冲的雷电能量泄放入地的做法与直击雷的处理方法相同,因而电子设备抗雷电电磁脉冲的局部设计不能只停留在电磁兼容层面上,在屏蔽、接入浪涌保护器、滤波等措施的同时也必须接地。     

Compulsory schooling,education, depression and memory: New evidence from SHARELIFE

In this paper we provide new evidence on the causal effect of education on adult depression and cognition. We use SHARE data and schooling reforms in several European countries as instruments for educational attainment. We find that an extra year of education has a large and significant protective effect on mental health; the probability of suffering depression decreases by 6.5 percentage points. We find a large and significant protective effect on cognition as measured by word recall. We also explore whether heterogeneity and selection play a part in the large discrepancy between OLS and IV (LATE) estimates of the effect of education on depression and cognition. Using the data available in SHARELIFE on early life conditions of the respondents such as the individuals’ socioeconomic status, health, and performance at school, we identify subgroups particularly affected by the reforms and with high marginal health returns to education.     

HILS setup of dynamic flight path planning in 3D environment with flexible mission planning using Ground Station

This paper reports the creation of the HILS setup to simulate the performance of the AUS-UAV system and the Ground Station. The paper will give an overview of the integration of the Ground Station created using a guide, the Avionics Unit created using an embedded system, integrated with various sensors, and the simulator created using simulink/flight simulator combination. The simulation will show the Ground Station and the embedded system working cooperatively to guide the UAV through several mission waypoints in three dimensions (3D). The paper focuses on the algorithm used to create paths in 3D, and also the organization of waypoints to achieve a specific goal. The paper also details the testing of the HILS.     

软基条件下客运专线900T箱梁预制场的基础设计

随着全国铁路建设的全面开展,高速铁路和客运专线建设也进入了高速发展时期。目前,我国高速铁路和客运专线主要采用预制箱梁,因此,铁路建设沿线要修建大量的制梁场。由于梁体自重大,梁体的变形要求高,对梁场的地基有很高的要求。结合中铁十四局集团公司广深港客运专线ZH-1标制梁场的地基处理施工过程,针对制梁场地基土质复杂、所受荷载大和控制变形的标准要求高的特点,制梁场设计方案的优化与施工进行综合的论述。
