Three emotion work themes were displayed in the discourse of individuals who lost their jobs and of their family members. Foregrounding-backgrounding of emotions indicated not only how some individuals and family members exerted effort to express positive emotions, but also why they would do so (for deep authenticity). In the construction of normalcy, respondents made an effort to portray and enact their lives as similar to the way things were before the job loss. By (re)instituting traditional masculinities, the men who lost their jobs were able to be "real" men in an emasculating situation. Taken together, these findings offer possibilities for further theoretical development and for communication interventions that can be applied by human resource professionals, career and outplacement counselors, family members, friends, and the individuals themselves.  相似文献

The effects of initial conditions on the flight of an American football kicked in an end-over-end manner were investigated using a dynamic simulation employing the quaternion method. The effects of initial tilt and spin about the longitudinal axis of the ball were considered. For the most accurate kick, our simulations show that the ball should be vertical leaving the kicker’s foot, and have no angular velocity about the longitudinal axis of the ball. A case study was performed for which experimental data were available, showing the trends of the flight of the ball captured in our simulations in actual game situations.  相似文献

Strategic alignment involves the development and reconfiguration of information technology (IT) to support business strategies. This paper applies the dynamic capabilities perspective to analyze the strategic information system alignment process. The paper further argues the approach is constructive in understanding and overcoming difficulties in achieving and sustaining alignment. From a longitudinal case study of a semiconductor company in Taiwan, the results show an unaligned strategic information system (with an implemented IT strategy that varies from the intended IT strategy) impedes the development of IT. Path dependence, or the implications of prior IT decisions, is another barrier for alignment. A broader view of intended alignment, focusing on IT combined with clear business vision, can be beneficial for adding future IT resources. In addition, dynamic capabilities, which are critical for the creation and strength of IT resources, positively influence the alignment process and its future implementation success.  相似文献

Children at risk for early reading difficulties were identified on entry into kindergarten, and half of these children received small-group intervention two to three times a week during their kindergarten year. The other half received whatever remedial assistance was offered by their home schools. These children were again assessed at the beginning of first grade, and those who continued to have difficulties in reading received either one-to-one daily tutoring offered by project teachers from the beginning to the end of first grade or whatever remedial assistance was offered by their home schools over the same time period. All target children were periodically assessed through the end of third grade. Results suggest that either kindergarten intervention alone or kindergarten intervention combined with first-grade intervention are both useful vehicles for preventing early and long-term reading difficulties in most at-risk children.  相似文献

We investigated perceptions about learning strategy use and instructional roles among a sample of high needs adolescents (n = 230) who acted as near-peer instructional facilitators. The sample was drawn from science and mathematics classes in nonselective public secondary schools in New York City. Students participated in an inschool intervention that draws on social constructivism, theory and research on metacognition and learning strategies, role theory, and empirical findings from the peer-to-peer learning literature to promote advanced achievement among students who act as facilitators. Using a pre- and post-test single group design, we surveyed student instructional facilitators before and after program participation and related their perceptions about learning strategy use and perceptions about teaching roles to data about academic achievement. We found no survey gains in student perceptions about learning strategies or instructional roles between pre-survey (fall) and post-survey (spring). We found small but significant effects of individual perceptions about learning strategies and teaching roles on academic gains among instructional facilitators. The study also suggests that an in-school near-peer facilitated learning program can be an effective means to raise achievement in urban high schools. The study provides partial support for theories that hold that metacognition and role perceptions are involved in the academic gains of instructional facilitators, as gains in these dimensions were small compared to achievement gains.  相似文献

Are all states and nearly all districts claiming that their students are above the national average? If so, are the test results “inflated and misleading?” What are the factors that contribute to the abundance of “above average” scores?  相似文献

顺应全球化:发展中国家高等教育的变迁与改革   总被引:8,自引:0,他引:8  
随着全球化经济就业模式的变化及对技能的需求 ,高等教育的内涵出现了变化。旨在满足国家优先发展战略的自上而下的高等教育投资政策已难以满足大众的迫切需求 ,基于个人和社会需求的自下而上的决策观更能满足人才、职业全球流动性日益增加的社会现实。根植于学术研究的知识生产模式难以在新形势下发挥作用 ,而与自下而上的政策建构相适应的知识生产模式 ,将有利于发展中国家在国际高等教育市场中保持竞争力  相似文献

The effects of signaled reward were examined using DRL and DRH schedules of reinforcement. In each case, one group of rats received a brief cue between the reinforced response and the reward, and a second group received brief cues at random times. With the DRL schedule (Experiment 1), signaled reward decreased response rate, increased response efficiency (number of responses per reinforcer), and increased resistence to satiation relative to the control group. With the DRH schedule (Experiment 2), signaled reward increased response rate, efficiency, and resistance to satiation. These results refute an overshadowing explanation of the effects of signaled reward and suggest that food-correlated cues enhance learning of the reinforcement contingencies.  相似文献
