In recent years rank and file leaders within labor unions have risen to challenge incumbents. This paper offers an addition to Herbert W. Simons’ theory on phases of leadership in certain types of social movements by examining the rhetoric of two union leaders who represent the dissident rank and file within the United Mine Workers of America and the United Steelworkers of America. Both men call for adaptation, renewal, and a new type of labor leader.  相似文献

A series of studies present the development and validation of the Communication Anxiety Regulation Scale (CARS), a self-report measure designed to assess the use of emotion regulation strategies to manage acute communication anxiety—in contrast to measures of general emotion regulation tendencies. Study 1 delineates the item derivation and selection process that yielded the final 12 CARS items. Results of an exploratory factor analysis supported the existence of four distinct subscales, each representing one of four anxiety regulation strategies (suppression, reappraisal, avoidance, and venting). Study 2 confirmed this factor structure and also examined correlations of the CARS with existing measures in an attempt to establish concurrent validity. Finally, Study 3 presents results of an item-sort task demonstrating the scale’s face validity and items’ substantive validity. Overall, findings provide preliminary support for the utility of the CARS as measure of communication anxiety regulation to be used by communication and psychology researchers.  相似文献

This essay seeks to establish a metaphor of the professional practice of teaching to the attributes and training of an offensive lineman in the game of American football. Effective classroom instruction does not rely exclusively on a rare set of talents but rather rests on the commitment to the work of teaching. Like the position of offensive lineman, the profession of teaching is one of service. And more, it is one in which the person's performance can blossom through intense determination. An invitation is offered to serve as an effective teacher.  相似文献

Social dominance orientation (SDO), right-wing authoritarianism (RWA), and socially desirable responding were examined among a sample of self-identified supporters of gifted education (N = 341), 70% of whom had an official role in gifted education as researchers, teachers, or gifted-talented (G/T) trainers. The sample was primarily female, White, well-educated, and upper middle class. The relationship of SDO, RWA, socially desirable responding, and support for various gifted education practices such as testing for identification, curricular differentiation in a heterogeneous classroom, and cooperative learning was explored through latent class analysis and logistic regression. Two distinct groups, communitarians and individualists, were found on the basis of their support for different gifted programming. Higher deference to authority among communitarians predicted support for an inclusive social norm, compared to a preference for maximizing potential without regard for inclusion among the individualists, who were less likely to defer to authority.  相似文献

In an era where technology is advancing at a rapid pace, and where information is readily accessible on the World Wide Web, educators should be capitalizing on these resources for gifted students. This paper proposes a conceptual framework to support individualized and independent learning within a network of peers that will provide challenging interactions through extensive use of online learning. Online resources and technologies promote the exploration of new concepts and sharing of new learning with a group of motivated and “like‐minded” peers.  相似文献

This article describes the development and implementation in the schools over a 20-year period of the Energy Source Program, a comprehensive K-12 energy education curriculum. The program was developed beginning in 1980 using state-of-the-art development procedures for that time and has been used to date by more than 12 million American students to learn about energy and energy issues. End-of-unit posttest scores for the elementary and high school units averaged above 80% for their field tests. Data obtained from a large sample during the first three years of installation of the program in the schools indicated that posttest scores remained at a level during installation similar to that during the field-test phase. A study conducted in the early 1990s by an independent research organization to assess the program's long-term effects revealed that grade 6 students who had used one or more units from the program had significantly greater energy knowledge and better energy conservation habits than students who had not used any units. A set of 10 guidelines are offered for long-term instructional development and implementation projects. He supervised the development of the Energy Source Program from 1980 to 1984 while serving as a consultant to EDS. Kay Ice was Director of Program Development at EDS, and she was a primary writer and developer of the Energy Source Program. She has been president of EDS since 1999. Fred Niedermeyer was the founding president of EDS. He was project director of the Energy Source project, and he played a major role in all aspects of the project from its inception until his retirement in 1999.  相似文献

The aim of this study was to ascertain if gear ratio selection would have an effect on peak power and time to peak power production in elite Bicycle Motocross (BMX) cyclists. Eight male elite BMX riders volunteered for the study. Each rider performed three, 10-s maximal sprints on an Olympic standard indoor BMX track. The riders’ bicycles were fitted with a portable SRM power meter. Each rider performed the three sprints using gear ratios of 41/16, 43/16 and 45/16 tooth. The results from the 41/16 and 45/16 gear ratios were compared to the current standard 43/16 gear ratio. Statistically, significant differences were found between the gear ratios for peak power (F(2,14)?=?6.448; p?=?.010) and peak torque (F(2,14)?=?4.777; p?=?.026), but no significant difference was found for time to peak power (F(2,14)?=?0.200; p?=?.821). When comparing gear ratios, the results showed a 45/16 gear ratio elicited the highest peak power,1658?±?221?W, compared to 1436?±?129?W and 1380?±?56?W, for the 43/16 and 41/16 ratios, respectively. The time to peak power showed a 41/16 tooth gear ratio attained peak power in ?0.01?s and a 45/16 in 0.22?s compared to the 43/16. The findings of this study suggest that gear ratio choice has a significant effect on peak power production, though time to peak power output is not significantly affected. Therefore, selecting a higher gear ratio results in riders attaining higher power outputs without reducing their start time.  相似文献
