This study examined the work ethic of manufacturing machine operators between self‐directed work teams and traditional work groups using four work ethic subscales: dependable, considerate, ambitious, and cooperative (Dawson, 1999 ; Petty, 1991 ). Differences in measured work ethic scores were also compared across six demographic variables: age, gender, level of education, years of full‐time work experience, years of experience as a supervisor, and work shift preference. Findings showed that there were significant differences in the work ethic between those two team structures and age groups. Implications for future research were presented. 相似文献

Psychodrama was first introduced in the Korean literature in 1972, but its generalization to college students did not occur until the 1990s. Despite findings from psychodrama studies with Korean college students supporting psychodrama as effective for developing and maintaining good interpersonal relationships, as well as decreasing anxiety and stress, it is still underutilized in South Korea. Accordingly, the current study looked at implementing a psychodrama program in South Korean universities. The positive results of the program implementation suggest that psychodrama is a useful technique for improving Korean college students’ general development and mental stability including secure attachment. 相似文献

Recently, proponents of interfirm R&D collaboration have emphasized its benefits. We develop a dynamic model of Schumpeterian competition to examine whether such collaboration is indeed beneficial in the long run. We find that interfirm R&D collaboration is more likely to be a losing strategy when partners form alliances mainly to reduce R&D costs. On the other hand, partners collaborating to seek synergy by accessing each other's complementary assets/capabilities are more likely to be successful. Our study suggests that firms should not use strategic alliances merely to reduce R&D costs in a catch-up situation or to avoid head-on competition with rivals. 相似文献

The purposes of this study were to characterise the golfer–ground interactions during the swing and to identify meaningful associations between the golfer–ground interaction force/moment parameters and the maximum clubhead speed in 63 highly skilled male golfers (handicap ≤ 3). Golfers performed shots in 3 club conditions (driver, 5-iron and pitching wedge) which were captured by an optical motion capture system and 2 force plates. In addition to the ground reaction forces (GRFs), 3 different golfer–ground interaction moments (GRF moments, pivoting moments and foot contact moments) were computed. The GRF moment about the forward/backward (F/B) axis and the pivoting moment about the vertical axis were identified as the primary moments. Significant (p < 0.05) correlations of peak force parameters (all components in the lead foot and F/B component in the trail foot) and peak moment parameters (lead-foot GRF moment and trail-foot pivoting moment) to clubhead speed were found. The lead-foot was responsible for generating the GRF moment, while the trail foot contributed to the pivoting moment more. The instant the lead arm becomes parallel to the ground was identified as the point of maximum angular effort, and the loading onto the lead-foot near this point was critical in generating both peak moments. 相似文献

This study explored the process of physics teaching assistants’ (TAs) PCK development in the context of teaching a new undergraduate introductory physics course. Matter and Interactions (M&I) has recently adopted a new introductory physics course that focuses on the application of a small number of fundamental physical principles to the atomic and molecular nature of matter. The purpose of this study is to describe how the PCK of physics TAs in the M&I course was developed and enacted. Data collection began during the TA preparation workshop that was held before the semester and continued during the recitation and laboratory classes that the TAs taught during the semester. Through a qualitative, multiple case study research design, data were collected from multiple sources: non-participant observations, digitally recorded video, semi-structured interviews, TAs’ written reflections, and researchers’ field notes. Data analysis consisted of cross-case and within-case analyses. Data were analyzed using a constant comparative method. After data analysis, 2 main themes emerged related to the development of TA’s PCK: (a) TAs’ PCK developed from propositional knowledge to personal practical knowledge and (b) the process of knowledge development consisted of 3 phases: accepting, actualizing, and internalizing. The results of this study will not only contribute to the quest to identify the nature of professional knowledge of science teaching but also help guide preparation for innovative introductory physics courses and other college level science courses in the future. 相似文献

As many Korean universities have recommended the implementation of mobile learning (m‐learning) for various reasons, the number of such tertiary learning opportunities has steadily grown. However, little research has investigated the factors affecting university students' adoption and use of m‐learning. A sample of 288 Konkuk university students participated in the research. The process by which students adopt m‐learning was explained using structural equation modeling technique and the Linear Structural Relationship (LISREL) program. The general structural model based on the technology acceptance model included m‐learning self‐efficacy, relevance for students' major (MR), system accessibility, subjective norm (SN), perceived usefulness, perceived ease of use, attitude (AT), and behavioral intention to use m‐learning. The study results confirmed the acceptability of the model to explain students' acceptance of m‐learning. M‐learning AT was the most important construct in explaining the causal process in the model, followed by students' MR and SN. 相似文献

The use of specially designed tasks to enhance student interest in the cadaver dissection laboratory
Cadaver dissection is a key component of anatomy education. Unfortunately, students sometimes regard the process of dissection as uninteresting or stressful. To make laboratory time more interesting and to encourage discussion and collaborative learning among medical students, specially designed tasks were assigned to students throughout dissection. Student response and the effects of the tasks on examination scores were analyzed. The subjects of this study were 154 medical students who attended the dissection laboratory in 2009. Four tasks were given to teams of seven to eight students over the course of 2 weeks of lower limb dissection. The tasks were designed such that the answers could not be obtained by referencing books or searching the Internet, but rather through careful observation of the cadavers and discussion among team members. Questionnaires were administered. The majority of students agreed that the tasks were interesting (68.0%), encouraged team discussion (76.8%), and facilitated their understanding of anatomy (72.8%). However, they did not prefer that additional tasks be assigned during the other laboratory sessions. When examination scores of those who responded positively were compared with those who responded neutrally or negatively, no statistically significant differences could be found. In conclusion, the specially designed tasks assigned to students in the cadaver dissection laboratory encouraged team discussion and collaborative learning, and thereby generated interest in laboratory work. However, knowledge acquisition was not improved. 相似文献

This research examined the structural relationships among transformational leadership, work engagement, knowledge creation practices, and the level of creativity among the teachers in career and technical education (CTE), and investigated the mediating role of work engagement and knowledge creation practices in explaining the association between transformational leadership and the level of teachers' creativity. A total of 304 responses from CTE school teachers were analyzed. The structural equation modeling (SEM) method was employed. Transformational leadership was found to have positive impacts on work engagement and knowledge creation practices of teachers, but no direct relationship was found between transformational leadership and the level of teachers' creativity. Teachers' work engagement and knowledge creation practices were respectively associated with their perceived creativity levels. Therefore, work engagement and knowledge creation practices of teachers may be considered as mediating factors in the relationship between transformational leadership and teacher's creativity. To promote teachers' creativity, transformational leadership should be complemented by a school climate where teachers' work engagement and knowledge creation are encouraged. 相似文献
