Evaluated the effect of relative deprivation on behalf of others (RDBO), social identification (IDEN), and intergroup differentiation (DIFF) on attitudes of men and their behavioral intentions concerning affirmative action strategies on behalf of women. The variables were integrated in a predictive model that was tested using path analysis. 122 male university students (aged 17–36 yrs) participated by responding to a questionnaire pertaining to IDEN, DIFF, RDBO, and intentions. Intentions to affirmative action strategies were influenced by social identity and RDBO. RDBO acted as a mediating variable between intergroup differentiation and intentions to implement affirmative action strategies. Results show that affirmative action can be positively received by males. (French abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

In summary, we have demonstrated a new method for the characterization of ultrashort pulses which can be easily implemented and which is particularly well suited to high intensity lasers. It is shown that it is possible to simply determine the temporal shape of femtosecond pulses using plasma-induced cross-phase modulation in ionized air 相似文献

A study has been performed to develop cost benefit data to be used by a local electric utility in defining a rebate program to encourage energy efficient construction in the Desert Southwest region of the USA. Several potential efficiency upgrades for production homes in the region were identified and an evaluation of each building component was performed using building energy simulation software. A model home developed in Las Vegas was used to calibrate the numerical model and was considered as a basis for further study. The validated building models were then used to predict the annual energy savings and payback periods for various upgrades. In all cases, comparisons were made to code-built houses with the same general overall characteristics. Useful life of most of these upgrades far exceeds their payback periods. It is found that a typical house, with the cost-effective upgrades installed, consumed 42.5% less annual energy compared to a home built to code. A 3.19 kWp PV system installed on the south-facing roof of the home can generate 5982 kWh annually, making it a net-zero (electrical) energy home. PV systems in Las Vegas have encouraging benefit cost ratios when federal and state rebates are considered. 相似文献

机器人操作器姿态性能的自动测量 总被引:1,自引:1,他引:0
本文介绍了作者在里昂国立应用科学学院工业自动化实验室发展的一个无机械接触的姿态性能自动测量系统.该系统由测量头、靶子和数据采集、处理子系统构成.测量头是一铅质直角三面体.其上装有六个感应式位移传感器;靶子是一钢质直角三面体.与被测机器人相联接;靶子相对测量头的姿态可根据传感器给出的距离数据算出,一台微计算机管理着数据的自动采集处理以及与机器人控制器之间的通信与协调动作,对两台机器人进行的实际测量应用.已展示了一些有意义的结果;同时也表明,该测量系统可以在工业环境中可靠和方便地用于多种工业机器人的姿态重复性和动态性能的测试,并且具有造价低,适应性强和自动化程度高等特点. 相似文献

This paper describes a one-dimensional finite element approach using the method of weighted residuals for the solution of mass oscillations in a surge tank following sudden opening of the valve. At the instant the valve is opened an allowance is made for some flow from the supply tunnel, in addition to that from the surge tank. The theory is, therefore, only altered for the initial conditions by expressing the flow along the tunnel as a percentage of the flow in the penstock. Comparison is made with the experimental result for the maximum downsurge observed in a simple model surge tank. 相似文献
