The environmental economics literature emphasises the key role that environmental regulations play in stimulating eco-innovations. Innovation literature, on the other hand, underlines other important determinants of eco-innovations, mainly the supply-side factors such as firms’ organisational capabilities and demand-side mechanisms, such as customer requirements and societal requirements on corporate social responsibility (CSR). This paper brings together the views of these different disciplines and provides empirical insights on the drivers of eco-innovations based on a novel dataset of 1566 UK firms that responded to the Government Survey of Environmental Protection Expenditure by Industry in 2006. By applying the Heckman selection model, our findings indicate that demand factors affect the decision of the firm to undertake eco-innovations whilst these factors exhibit no impact upon the level of investments in eco-innovations. Hence, we suggest that firms initiate eco-innovations in order to satisfy the minimum customer and societal requirements, yet, increased investments in eco-innovations are stimulated by other factors such as cost savings, firms’ organisational capabilities, and stricter regulations. Based on a quantile regression analysis, the paper offers interesting insights for policy makers, by showing that the stringency of environmental regulations affects eco-innovations of the less innovative firms differently from those of the more innovative firms. 相似文献

Supply chain management principles have emerged in the last decade as a strategic option to meet new challenges in global business environment. Viewing business environment as part of a chain, starting from raw material suppliers to end customers passing by producers, is at the heart of supply-chain management. Many management principles have emerged for better planning and controlling this chain to the benefit of all parties involved. This paper explores the implications of supply-chain management principles on higher education. First, a supply-chain view of higher education is described and its environment is analysed for the possibility of adopting supply-chain principles. Features that might be catalysts or hurdles towards these principles are identified. Second, a framework for supply-chain coordination and integration in higher education that takes into consideration these features are developed. Finally, existing practices that address supply-chain in higher education are identified and some new practices representing a natural extension of supply-chain management practices are suggested. A potential case study for implementing these concepts is presented. 相似文献

This study presents a new theoretical and pedagogical framework based on the theories of Critical Religious Education (CRE), Variation Theory (VT) and the Learning Study model with the purpose of improving teaching and learning in Islamic Religious Education (IRE). It reports a Learning Study conducted in a secondary girls Muslim school in London on the topic of ‘Islam and being Muslim’. The aim of this research study is to examine if and how the proposed framework can be applied to IRE lessons, and how it affects the students’ learning. Thirty students of two seventh grade classes and their religious education teacher participated in the study. The data was collected through interviews and written tasks with the students before and after their participation in the study, video-recordings of the research lessons, and meetings with the teacher. Phenomenography and VT were utilised in the analysis of the data. The results suggest that the use of CRE, VT and Learning Study in teaching Islam contributes to students’ learning outcomes by means of helping teacher consider students’ diverse perspectives on religious phenomena when planning and implementing the curricular content, increasing students’ awareness of the ontological and epistemological dimensions of their faith as well as allowing them to make informed judgments about religious phenomena. 相似文献

Research Findings: The purpose of this study was to examine whether child temperament differentially predicted academic school readiness depending on the quality of classroom interactions for 179 Head Start preschoolers. Teachers rated children's temperament as overcontrolled, resilient, or undercontrolled in the fall and reported on children's language/literacy and math skills continuously throughout the year. Observations of classroom emotional and instructional support were conducted in the spring. Results from multilevel models indicated that overcontrolled children (compared to resilient children) made greater math gains in classrooms with higher instructional support, whereas a trend-level effect suggested that undercontrolled children (compared to resilient children) made lower math gains in classrooms with lower emotional support. Results also showed that resilient children's gains in language/literacy were more positively associated with high emotional support than were the scores of overcontrolled children. Practice or Policy: This study adds to prior findings suggesting that overcontrolled and undercontrolled children need special attention in the preschool classroom. Teachers and administrators may want to carefully consider the effect that classroom interactions and instructional techniques have on individual children and attempt to tailor instruction to meet the individual needs of children within classrooms. 相似文献

This study investigates how early childhood education (ECE) teachers incorporated digital storytelling in their classrooms and the challenges and successes that they faced in the process. After the teachers attended a digital storytelling workshop, in-depth phenomenological interview, observation and focus group interviews were used to collect data. Phenomenal data were collected from 5 kindergarten classrooms, each of which contained approximately 20 students and a teacher. The study presented examples that illustrated how ECE teachers had used digital storytelling to enhance learning. The results showed that an emphasis on specific points may assist teachers, parents, educational researchers and education policy-makers in using technological tools in young children’s learning environments. 相似文献

IntroductionTo interpret test results correctly, understanding of the variations that affect test results is essential. The aim of this study is: 1) to evaluate the clinicians’ knowledge and opinion concerning biological variation (BV), and 2) to investigate if clinicians use BV in the interpretation of test results.Materials and methodsThis study uses a questionnaire comprising open-ended and close-ended questions. Questions were selected from the real-life numerical examples of interpretation of test results, the knowledge about main sources of variations in laboratories and the opinion of clinicians on BV. A total of 399 clinicians were interviewed, and the answers were evaluated using a scoring system ranked from A (clinician has the highest level of knowledge and the ability of using BV data) to D (clinician has no knowledge about variations in laboratory). The results were presented as number (N) and percentage (%).ResultsAltogether, 60.4% of clinicians have knowledge of pre-analytical and analytical variations; but only 3.5% of them have knowledge related to BV. The number of clinicians using BV data or reference change value (RCV) to interpret measurements results was zero, while 79.4% of clinicians accepted that the difference between two measurements results located within the reference interval may be significant.ConclusionsClinicians do not use BV data or tools derived from BV such as RCV to interpret test results. It is recommended that BV should be included in the medical school curriculum, and clinicians should be encouraged to use BV data for safe and valid interpretation of test results. 相似文献

The purpose of the current study is to describe the development and validation of a new measure of temperament, the Preschool Temperament Classification System (PTCS). The PTCS was developed as a typological measure that identifies children's temperament styles as undercontrolled, resilient, or overcontrolled. The PTCS is a time efficient structured interview assessing children's temperament as it is observed in the classroom environment. During the 20 min interview, teachers classify all of the children in their class into one of the three temperament styles, rank order children within each temperament group, and assign an intensity rating to each child, indicating how well the child matches his/her assigned temperament group. Data were collected on 196 preschool-age children from 25 Head Start classrooms in an urban area. Teachers assessed children's temperament and peer play behaviors, and trained research assistants assessed children's school readiness. The PTCS classified children into temperament groups that showed expected relations to peer play competence and school readiness after controlling for age and gender, indicating good validity. Test–retest reliability was moderate to high. Overall the PTCS shows promise as a valid and reliable teacher measure of preschool children's temperament. 相似文献

The goal of this study is to determine the effectiveness of mind games played by secondary school sixth grade students as classroom activities in math and grammar courses on their perceived problem-solving skills and achievements. In the quantitative part of the study, the nonequivalent groups pre-test–post-test control group design from single-factor quasi experimental designs was used. Qualitative data collection and analysis approaches have also been used to support and explain quantitative data. The study's sample group, which was formed using a convenience sampling method, consisted of 48 sixth grade secondary school students who studied in a moderately developed city center in Turkey and their teachers. An achievement test, perceived problem-solving skills scale and semistructured interview guide were used as the data collection tools. According to the findings, the students in the experimental group who played mind games showed development in their perceived problem-solving skills and achievements compared to the control group. The opinions of the teachers and students on the effects of the mental practices were also found to be positive. 相似文献

Educable mental retardation is a delay in acquiring basic reading, writing and counting skills emerging through late speaking and linguistic development along with social, emotional or behavioral problems. It is pointed out that such children have intelligence in the 45-74 range, and that they are incompetent in terms of language skills, perception power, memory capacity, imagination and creativeness. Primary school curriculum for educable mentally retarded children was adopted so as to implement beginning in 2001-2002 academic year. The curriculum was designed so as to apply in primary education schools where educable mentally retarded children attend or in private classes included in the body of primary education schools. It was designed in order for such children to improve their skills of understanding themselves, establishing positive social relations, adjusting to the social, technological and physical environment, and surviving independently. This current study is based on a qualitative method, and is focused on educable mentally retarded children who are at primary school age in Turkey. Having described the characteristics of such children, their needs are explained, the curriculum developed for such children is described, and teachers＇ views concerning the implementation of the curriculum are presented in this research. 相似文献
