Key personality traits of engineers for innovation and technology development

Focusing on new roles of engineers for technological innovation and internal entrepreneurship, we examined the personality traits of 4876 engineers versus 75,892 non-engineers. Engineers scored higher on Tough-Mindedness and Intrinsic Motivation; but lower on Assertiveness, Conscientiousness, Customer Service Orientation, Emotional Stability, Extraversion, Image Management, Optimism, Visionary Style, and Work Drive. All but four of these traits were positively related to engineers’ career satisfaction. Overall, the results are not encouraging for the new roles of engineers such as intrapreneurship. Findings were discussed in terms of occupational profiling of engineers as well as career planning, selection, training, and professional development of engineers.     

Half-sample variance estimation

This paper studies an alternative to the jackknife variance estimator, the half-sample variance estimator. Both theoretical and Monte Carlo comparisons between the half-sample variance estimator and the jackknife variance estimator indicate that the former is better in some situations.     

Health Technology Literacy: A Transdisciplinary Framework for Consumer-Oriented Practice

Abstract

The present study developed a typology of self-reported coping strategies used by older adults in adapting to vision impairment using qualitative analyses. Narrative data were examined from three previous quantitative studies of adaptation to vision loss. Major themes in coping with vision loss included difficulty in balancing norms of independence with the functional losses resulting from eye disease, and the importance of the informal social network. Importantly, a number of coping mechanisms that have not been examined in prior quantitative work were identified through the present qualitative analyses. Implications of this typology of self-reported coping with age-related vision loss for research and practice are discussed.     

Dimensions and design criteria for developing training reaction evaluations

Although there is research on training program evaluation, there is little systematic research on the design, development and use of training reaction evaluations. In order to obtain meaningful information from a program evaluation, evaluation professionals must be rigorous in the design and development of all aspects of an evaluation study, including instrumentation. The purposes of the study were to classify the dimensions of information sought using reaction evaluations and to establish design criteria for developing training reaction instruments. There were three major phases of the study: (1) classification of the dimensions and questionnaire design criteria used in reaction evaluations; (2) validation of the classified dimensions and the questionnaire design criteria by subject matter experts; and (3) assessment of a sample of training reaction instruments currently used in training programs in US corporations. The research findings were: eleven dimensions for reaction evaluation were identified and classified by purpose. Five overall design criteria, each consisting of several sub-criteria, were judged important in the design of reactionnaires. These include: introduction and directions; question format; question construction; questionnaire layout; and data analysis. It was concluded that a well-designed training reaction instrument integrates the proper application of design criteria with appropriate reaction dimensions. Most training reaction instruments used by US corporations consisted of questions representing only a few dimensions. The instruments varied in form and length. Few of them properly utilized the established questionnaire design criteria.     

Ka频段矩形波导——微带转换结构

提出了一种波导到微带过渡结构的同轴探针过渡。该结构具有结构紧凑、频带宽、密封性好等优点,可以满足实际工程中对矩形波导输入口不同极化方向的要求,其波导输出端口以同轴探针为中心任意角度旋转,为射频系统工程师提供更灵活的设计方案。利用Advanced Design System(ADS)对提取电路进行了电路仿真,并与CST Microwave Studio(CST)场仿真结果进行了对比,证明了电路提取的正确性。设计加工了一对背靠背的电路进行测试,在28.8~40 GHz频段内插入损耗小于2.28 dB,回波损耗大于7.8 dB。

民主化科学化语境下党管干部制度的变革探究

面对全球化、市场化与民主化的挑战,如何完善党管干部的方式和方法以适应新的世情、国情、党情,是关系到中国共产党的执政能力和执政地位的重大问题。长期以来,我们在党管干部的问题上,重使用、轻管理,重提拔、轻监督。要解决党管干部管的方向和动力问题,就必须坚持和完善党管干部制度的民主化与科学化。     

长江中游牯牛沙水道航道整治一期工程效果分析

牯牛沙水道为长江中游近期出现的重点碍航浅水道,整治好该水道对长江中游航道的畅通具有重要意义。交通运输部于2010年2月批复同意实施该水道航道整治一期工程。简介牯牛沙水道演变特点、主要影响因素、碍航特性与整治方案,详细分析牯牛沙水道整治前后过渡段变化情况、牯牛沙边滩淤积情况以及航道改善情况,重点分析一期工程整治效果,预测演变趋势,提出后续工程建议。一期工程实施后,工程效果良好,总体河势更趋稳定,牯牛沙边滩淤高展宽,利于枯水期水流集中,过渡段浅埂得到较为有效冲刷,淤积减少,碍航程度减轻,浅区航道条件改善,为后续工程的实施创造了有利条件。分析认为:一期工程效果将会随着建筑物功能的继续发挥进一步显现,达到预期目标。
