Glamour of Dunhuang Fascinates French Viewers     

Lea Wu Wu Gang 《中外文化交流(英文版)》2009,(3):20-23

Dunhuang Grotto Temple is the world＇s largest extant treasure house of grotto art. Exquisite mural paintings and painted sculptures from ancient China are well preserved in hundreds of temple caves. In 1900 a local young Taoist monk named Wang Yuantu accidentally discovered, from grotto walls, sutra collection caves that had bean sealed for years. In those caves are kept numerous volumes of writings, silk paintings and painted banners. This accidental discavery unveiled the mysterious history of Dunhuang that dates back to more than one thousand years.  相似文献   

The Simple View of Reading in Bilingual Language-Minority Children Acquiring a Highly Transparent Second Language     

Paola Bonifacci  Valentina Tobia 《Scientific Studies of Reading》2017,21(2):109-119

The present study evaluated which components within the simple view of reading model better predicted reading comprehension in a sample of bilingual language-minority children exposed to Italian, a highly transparent language, as a second language. The sample included 260 typically developing bilingual children who were attending either the first 2 years (n = 95) or the last 3 years (n = 165) of primary school and who had Italian as an instructional language. Children were administered a comprehensive battery for the assessment of decoding skills, listening comprehension, and reading comprehension latent variables. Results showed that, in both groups, listening comprehension was the most powerful predictor of reading comprehension, followed, only for younger children, by reading accuracy. Reading speed was not a significant predictor. These results confirmed the primary role of listening comprehension in predicting reading comprehension in bilinguals and added important evidence regarding the role of reading accuracy as a predictor of reading comprehension.  相似文献   

The impact of entrepreneurial capacity, experience and organizational support on academic entrepreneurship     

Bart Clarysse  Valentina Tartari  Ammon Salter 《Research Policy》2011,40(8):1084-1093

Although sources and determinants of academic entrepreneurship have begun to command the attention of policy-makers and researchers, there remain many unanswered questions about how individual and social factors shape the decisions of academics to engage in entrepreneurial activities. Using a large-scale panel of academics from a variety of UK universities from 2001 to 2009, this paper examines how an academics’ level of entrepreneurial capacity in terms of opportunity recognition capacity, and their prior entrepreneurial experience shape the likelihood of them being involved in starting up a new venture. In addition, we explore what role university Technology Transfer Offices (TTOs) play in stimulating venture creation. The results show that individual-level attributes and experience are the most important predictors of academic entrepreneurship. We also find that the social environment surrounding the academic also plays an influential role, but its role is much less pronounced than individual-level factors. Finally, we show that the activities of the TTO play only a marginal, indirect role, in driving academics to start new ventures. We explore the implications of this analysis for policy and organizational design for academic entrepreneurship.  相似文献   

Countermovement jump performance assessment using a wearable 3D inertial measurement unit     

Picerno P  Camomilla V  Capranica L 《Journal of sports sciences》2011,29(2):139-146

The aim of this study was to validate a wearable inertial measurement unit (IMU), containing a 3D accelerometer and gyroscope, for the estimation of countermovement jump height. The absolute vertical acceleration of the IMU positioned on the back of the participant at L5 level, compensated for trunk rotations, was used to obtain jump height by applying the equation of free-fall to the motion of the IMU. The methodology was tested on 28 participants performing five countermovement jumps each. A reference value for this quantity was obtained using stereophotogrammetry (35.4 cm, s = 4.9). Jump height scores obtained using the proposed methodology (35.9 cm, s = 5.5) presented no significant difference with respect to stereophotogrammetry (P = 0.61). A low bias of 0.6 cm confirmed the accuracy of the estimate, which also showed a high (r = 0.87) and significant (P < 0.0001) correlation with reference values. Furthermore, without compensating accelerations for trunk rotation, jump height was largely underestimated (P < 0.0001) (bias: -12.7 cm) and poorly associated (r = 0.31) with stereophotogrammetry. The results of this study show that the estimation of jump height using inertial sensors leads to accurate results when the measured accelerations are corrected for trunk rotations.  相似文献   

The Viability of Combining Academic and Career Pathways: A Study of Linked Learning     

Lea Hubbard  Mary McDonald 《Journal of Education for Students Placed at Risk》2014,19(1):1-19

In an attempt to reform high schools and prepare students with the knowledge and skills needed for the 21st century, educators and policymakers have turned to programs that combine career and academic pathways. One such program, Linked Learning, has taken up the reform challenge by relying on technical adjustments, rearranging students’ schedules, and integrating career technical education (CTE) with a set of courses that support students’ eligibility for their state and university college system. Linked Learning has attempted to avoid the pitfalls often associated with an earlier vocational education model. This article reports findings from a year-long study of eight schools in five districts whose district leaders and principals have placed Linked Learning at the core of their platform for school reform. Interviews with these educators reveal that while changing the structure of students’ course schedules offered some advantages for students, school principals were challenged to keep their academic and career promises. This qualitative investigation has shown that to understand reform challenges it is essential to examine the broader school, district, and state context in which the reform is embedded. Both structural and cultural considerations must be addressed if high school reform is to more effectively support students.  相似文献   

Environmental innovation and R&D cooperation: Empirical evidence from Spanish manufacturing firms   总被引：2，自引：0，他引：2  

Valentina De Marchi 《Research Policy》2012,41(3):614-623

This paper explores the relationship between firms’ R&D cooperation strategies and their propensity to introduce environmental innovations.Previous literature has supported that environmental innovations differ from other innovations as far as externalities and drivers of their introduction are concerned, highlighting mainly the importance of regulation to trigger them. Using data from the Community Innovation Survey on Spanish manufacturing firms (PITEC), this paper investigates specificities that affect rather how they are developed, and in particular the higher importance of R&D cooperation with external partners.The econometric estimations, controlling for selection bias, suggest that environmental innovative firms cooperate on innovation with external partners to a higher extent than other innovative firms. Furthermore, cooperation with suppliers, KIBS and universities is more relevant than for other innovators, whereas cooperation with clients does not seem to be differentially important. Finally, the results bespoke of a substitution effect between cooperation activities and the internal R&D effort.  相似文献

Identification of the materials used in an Eastern Jin Chinese ink stick     

Shuya Wei  Xiaoyang Fang  Jun Yang  Xuejun Cao  Valentina Pintus  Manfred Schreiner  Guoding Song 《Journal of Cultural Heritage》2012,13(4):448-452

Chinese ink stick has a long history and a special importance in the Chinese culture. For the first time, Pyrolysis Gas Chromatography and Mass Spectrometry (Py-GC/MS) was used to identify the materials in an ancient Chinese ink stick. Four types of constituents could be detected in the archaeological ink stick of the Eastern Jin period (317–420 AD): (1) borneol (Chinese name bing piàn); (2) compounds related to essential oil or tar of conifer wood: cedrene, aromadendrane, cedrane, cuparene, cedrol, retene, methyl dehydroabietate and 9-methyl retene; (3) marker compounds from animal glue; (4) polycyclic aromatic hydrocarbons (PAHs) from soot. The information obtained through this study provides conclusive evidence for use of additives of borneol and cedar oil, binding media of animal glue and pine wood soot in the ancient ink stick.  相似文献   

Voices of university students with disabilities: inclusive education on the tertiary level – a reality or a distant dream?     

Iva Strnadová  Vanda Hájková  Lea Květoňová 《International Journal of Inclusive Education》2013,17(10):1080-1095

Twenty-four university students with disabilities were interviewed about their experiences studying at Czech universities. The interviews were analysed using the grounded theory approach. The most commonly experienced barriers faced by these students were institutional barriers, attitudinal barriers, and disability-specific barriers. The types of support mentioned by the students included family support, peer support, and support provided by assistants. The participants also shared strategies they used to deal with the barriers they faced. These were assertiveness, self-determination, metacognition, efforts to ‘fit in’, optimism, and career planning. The implications for policy and universities are discussed.  相似文献
