Relationships amongst cultural dimensions,educational expenditure and class size of different nations     

Hoi Yan Cheung  Alex W.H. Chan 《International Journal of Educational Development》2008

Many studies have concentrated on investigating educational expenditure and pupil–teacher ratio to see how these two factors can influence the quality of education. This study chooses to examine these two educational factors from a different perspective. If educational expenditure and pupil–teacher ratio really have a significant impact on the quality of education as many studies have claimed, it is important to step back and understand why some regions choose to have high/low educational expenditure and high/low pupil–teacher ratios. This study found that culture has an important impact on these two educational factors. Hofstede's cultural dimensions, namely Power Distance and Individualism, were applied and results showed that these two cultural dimensions, when applied to 43 regions around the world, demonstrated a significant impact on educational expenditure and pupil–teacher ratio.  相似文献   

Building a model to define the concept of teacher success in Hong Kong     

Cheung Lai-man Elizabeth  Cheng May-hung MayPang King Chee 《Teaching and Teacher Education》2008

The research studies how outstanding teachers from Hong Kong conceptualize teacher success or effectiveness. This study adds to the knowledge base concerned by raising the importance of the coexistence of personal attributes and professional qualities as well as contextual factors, in bringing out the success of a teacher. It draws the attention of teacher educators/trainers and school administrators to the necessity of viewing the concept of teacher success from a broader perspective, instead of focusing narrowly on the professional qualities of a teacher. It also provides insights for school administrators in selecting teachers or supporting their work.  相似文献   

Impacts of Globalization on E-Commerce Use and Firm Performance: A Cross-Country Investigation     

Kenneth L. Kraemer  Jennifer Gibbs  Jason Dedrick 《The Information Society》2005,21(5):323-340

This article develops and tests a model examining the relationship between firm globalization, scope of e-commerce use, and firm performance, using data from a large-scale cross-country survey of firms from three industries. We find that globalization leads to both greater scope of e-commerce use and improved performance, measured as efficiency, coordination, and market impacts. Scope of e-commerce use also leads to greater firm performance of all three types. Globalization has differential effects on B2B and B2C e-commerce, however, such that highly global firms are more likely to do B2B but less likely to do B2C. Our findings provide support for Porter's (1986) thesis that upstream business activities (namely, B2B) are more global while downstream business activities (B2C) are more local or multidomestic.  相似文献   

Digital redesign tracker for cascaded analog systems with state saturation and external loads     

Jason Sheng-Hong Tsai  Meng-Che Wu  Leang-San Shieh 《Journal of The Franklin Institute》2005,342(7):852-876

This paper presents a newly developed digital redesign control scheme with a weighted switching strategy and output-reference tracking, for a cascaded analog system with state saturation and external loads. The proposed method improves the generally poor transition response and output deviation caused by state-saturation constraint and external loads. It replaces an existing or theoretically well-designed analog controller with state saturation, by a digital controller with almost identical performance.  相似文献

The expanding role of university patenting in the life sciences: assessing the importance of experience and connectivity     

Jason Owen-Smith 《Research Policy》2003,32(9):1695-1711

We extend debates about the sources of university capabilities at research commercialization. Drawing upon quantitative data for a panel of 89 research-intensive US universities and interview data from two academic licensing offices, we model the relationship between technology transfer experience, embeddedness in biotechnology industry networks, basic science quality and capacity, and citation impact measures of university life science patents. Technology licensing officers draw upon the expertise of corporate partners to evaluate the potential impact of invention disclosures. The information gleaned through network ties to industry enables well-connected institutions to develop higher impact patent portfolios. Reaping the benefits of such connections, however, requires experience in balancing academic and corporate priorities to avoid the danger of ‘capture’ by industrial interests as overly tight connections limit patent impact. This pattern of diminishing returns to connectivity is robust across multiple citation measures of patent quality.  相似文献   

Static and dynamic behavior of concrete slabs reinforced with chemically reactive enamel-coated steel bars and fibers     

Dong-ming Yan  Shi-kun Chen  Gen-da Chen  Jason Baird 《浙江大学学报(A卷英文版)》2016,17(5):366-377

In this study, the effect of steel fibers coated with chemically reactive enamel (CRE) on the system response of concrete structures with reinforcing bars has been investigated for the first time. In particular, the ultimate strength, ductility, and failure mechanism of 24 reinforced concrete slabs were experimentally characterized under static and blast loads. CRE coating applied on steel bars reduced the crater area of slabs under blast loads by up to 20%; it slightly increased the strength of slabs and significantly reduced the strength degradation of slabs when increasingly deflected under static loads, making the slabs more ductile. CRE coating applied on steel fibers increased the strength of slabs by up to 16% under static loads. The influence of CRE coating applied on both steel fibers and bars may be taken into account by introducing a coating factor in the range of 0.57<β<1.0 in the American Concrete Institute (ACI) development length equation.  相似文献   

Developing students' critical thinking skills through visual literacy in the New Secondary School Curriculum in Hong Kong     

Chi-Kim Cheung  Aditi Dubey Jhaveri 《Asia Pacific Journal of Education》2016,36(3):379-389

This paper argues that the planned introduction of visual literacy into the New Secondary School Curriculum can play a crucial role in enabling students to think critically and creatively in Hong Kong's highly visual landscape. As Hong Kong's educational system remains entrenched in long-established and conventional pedagogies, the primacy given to the written word is in sharp contrast with the pragmatic roles that visual images play in students' day-to-day life. Hong Kong is well-known for its extremely high level of Internet / broadband penetration and media saturation, yet visual literacy is still in a state of infancy in Hong Kong. Therefore, from a curricular standpoint, as Hong Kong society relies to a greater degree than ever before on visual communication strategies, it is vital that visual literacy be integrated as part of the new curriculum under the current educational reforms. As contemporary Hong Kong culture becomes increasingly dependent on the visual environment, developing visual literacy to enhance students' learning can be an important step in the future towards a more successful implementation and development of the New Secondary School Curriculum.  相似文献
