Radio Frequency Identification (RFID), once a niche technology, is rapidly gaining the attention of retailers as a key enabler in their supply chain. As RFID moves into the mainstream, it is poised to replace the standard barcode as the technology that identifies and tracks products throughout the supply chain. In an attempt to gain competitive advantages, some retailers have begun the transition to RFID while others have been reluctant to embrace it. This study investigates South Korean retailers to identify key organizational characteristics that positively drive the evaluation of RFID. Further, this study assesses the impact one's evaluation has on the adoption and integration of RFID within their respective firm. Results from 278 adopting organizations show organizational needs (Ubiquity and Performance Gaps), perceived factors (Benefits and Cost Savings), and organizational readiness (Financial Resources and Technological Knowledge) have a significant influence on RFID Evaluation; and evaluation impacts its adoption, and integration. 相似文献

This article offers an alternative model, the model of shared authority, to the traditional, authoritarian model for authority and obedience for Religious Education. This model moves away from the authoritarian model of a teacher as the authority and the students as obedient listeners in the direction of a shared authority model in which teachers and students participate in learning as partners, in other words, “to become co-authors.” 相似文献

The purpose of this study was to analyze student achievement data from the first 3 years of the Memphis Restructuring Initiative (MRI). The MRI represents one of the first efforts by an urban school district to move past traditional top-down versus bottom-up reform debates by providing systemic support for outside-in/inside-out implementation and local co-construction of externally-developed reform designs in schools. Analyses of academic achievement focus on a state-of-the-art measure of value added assessments. At the end of 3 years the reforming schools had produced generally positive gains relative to locally matched control schools. Those results varied somewhat by reform type and by level of poverty in the communities being served. Based on the research methods used and the results, implications for future research and practice in educational reform are discussed. 相似文献

A new primary science syllabus with strong inquiry focus has been implemented in Singapore since 2008. In this study, we attempted to understand how teachers experience the emphasis of inquiry-based curriculum under the current educational conditions that is routined and highly teacher fronted. We invited 50 pre-service and 41 in-service teachers to participate in survey questionnaires and narratives, reflective writings, and group discussions related to science inquiry which formed our data corpus. Data analysis in the form of thematic coding was carried out using NVivo8, with over 80% inter-rater coding agreement level. Three key aspects of teachers’ perceptions of science inquiry were revealed: (1) teachers’ responsibilities as facilitators, (2) privileging content knowledge rather than process skills, and (3) pressure of assessment systems in current educational contexts. These understandings bring out conflicts of inquiry teaching between teacher- and student-centredness, content and process, and curriculum and assessment. Based on these teachers’ perceptions and dilemmas of inquiry science teaching, the visions and challenges of inquiry science curriculum change against assessment requirements are discussed. 相似文献

The purpose of the study was to investigate the effect of different kicking modality, i.e., erratic-dynamic target (EDT) versus static target (ST) on the performance of the roundhouse kick in two groups of taekwondo athletes of different skill level. Three-dimensional analysis and surface electromyography (SEMG) analysis were performed on 12 (Group A: six sub-elite, Group B: six elite) athletes to investigate muscle co-activation pattern under two conditions, i.e., EDT versus ST. In the results, the muscle recruitment ratio of the agonistic muscles was higher for Group A, whereas Group B had higher recruitment ratio for antagonist muscles. Overall, the co-activation index (CI) of hip joints appeared higher in the extensors for Group A, whereas higher CI was observed in flexor muscles for Group B with comparatively higher CI during EDT condition than ST condition. Higher value of CI was observed in flexor muscles of the knee joints among Group A during EDT conditions, in contrast, higher CI in the extensor muscles was observed among Group B during ST conditions. In conclusion, the study confirmed that erratic-dynamic movements of target could change the movement coordination pattern to maintain the joint stability of participants. 相似文献
