The Diversity Mission Evaluation Questionnaire (DMEQ) was developed to assess attitudes, beliefs, and experiences pertaining to multicultural matters at a graduate program in psychology. Using scores of 247 students, 57 faculty, and 19 staff, the authors revealed three latent traits through exploratory factor analysis: Overall Success, Open Discussion of Diversity Issues, and belief that multicultural activities were Freely Undertaken. The high internal consistency of all of these scales, (as > .81), coupled with expected between-groups differences and significant correlations with experiences of prejudice, suggests that the instrument assessed diversity issues in a precise and valid manner. It was concluded that the DMEQ could be used by institutions desiring to assess their multicultural climates. Evaluative data from a graduate school that has adopted and implemented a diversity mission are presented, and issues related to multicultural change are discussed.

In this paper we address the support of wearable mHealth applications in LTE and future 5G networks following a holistic approach that spans across the elements of a mobile network. The communication requirements change from one application to another so we propose a measurement methodology to facilitate the selection of the user equipment to fulfil these requirements. We also discuss a new network architecture to support traffic prioritization, RAN programmability, low latency and group communications to over-the-top applications. Our proposal is validated using several realistic experimentation platforms and the results show that mHealth systems can benefit from our approach. 相似文献

研究导航线路优化问题,针对现实战场环境错乱复杂,飞行员要担负飞行规划和战斗规划双重任务,为了让飞行员航线规划中释放出来,需要实现自动航线规划技术为飞行任务提供辅助决策.为了准确快速自动地规划出从起点到终点之间的“最优”航线,提出采用双指标并行A*算法的自动航线规划算法,将三维地形、雷达探测范围和飞机性能约束结合到A*算法中,并使用并行程序设计思想解决了常规A*在搜索路径时耗时长的问题.在实现算法的基础上,编写程序进行仿真,多组仿真对比,结果验证了并行A*算法在解决自动航线规划问题时的有效性和高效性. 相似文献

Initiated in 1972, the Landsat program has provided a continuous record of earth observation for 35 years. The assemblage of Landsat spatial, spectral, and temporal resolutions, over a reasonably sized image extent, results in imagery that can be processed to represent land cover over large areas with an amount of spatial detail that is absolutely unique and indispensable for monitoring, management, and scientific activities. Recent technical problems with the two existing Landsat satellites, and delays in the development and launch of a successor, increase the likelihood that a gap in Landsat continuity may occur. In this communication, we identify the key features of the Landsat program that have resulted in the extensive use of Landsat data for large area land cover mapping and monitoring. We then augment this list of key features by examining the data needs of existing large area land cover monitoring programs. Subsequently, we use this list as a basis for reviewing the current constellation of earth observation satellites to identify potential alternative data sources for large area land cover applications. Notions of a virtual constellation of satellites to meet large area land cover mapping and monitoring needs are also presented. Finally, research priorities that would facilitate the integration of these alternative data sources into existing large area land cover monitoring programs are identified. Continuity of the Landsat program and the measurements provided are critical for scientific, environmental, economic, and social purposes. It is difficult to overstate the importance of Landsat; there are no other systems in orbit, or planned for launch in the short-term, that can duplicate or approach replication, of the measurements and information conferred by Landsat. While technical and political options are being pursued, there is no satellite image data stream poised to enter the National Satellite Land Remote Sensing Data Archive should system failures occur to Landsat-5 and -7. 相似文献
