危怀安  刘薛  姚远 《科学学与科学技术管理》2012,(5):22-28

作为我国基础研究"国家队"的重要组成部分,联合型SKL已经成为我国开展高水平基础研究的重要基地,但其原始创新和集成创新能力有限,且不同类型的联合型SKL自主创新绩效差异显著。首次运用SWOT法对我国联合型SKL自主创新进行了比较全面系统的分析。研究表明,我国联合型SKL在自主创新方面具有各自的优势和劣势,面临不同的威胁和发展的机遇。因此,发挥多种策略的协同功能,就成为提升我国联合型SKL自主创新能力的应对之策。  相似文献   

The role of copper on colour of palaeo-Christian glass mosaic tesserae: An XAS study     

Alberta Silvestri  Serena Tonietto  Francesco D’Acapito  Gianmario Molin 《Journal of Cultural Heritage》2012,13(2):137-144

This work reports mainly the results of an X-ray Absorption Spectroscopy (XAS) study carried out on coloured glass tesserae from the palaeo-Christian mosaic which decorated the votive chapel of St. Prosdocimus (Padova) until its replacement with the current frescoes of Renaissance age, and which is one of the only two known mosaics in the Veneto region (Italy). The study aims at clarifying how the different local structure, oxidation state and quantity of copper influenced colour. Analysis of high-resolution Cu-K edge X-ray Absorption Near Edge Structure (XANES) and Extended X-ray Absorption Fine Structure (EXAFS) spectra showed that copper is present as cuprite (Cu₂O) in orange samples and as metallic copper in red and brown ones. These phases are responsible for both the colour and opacity of the samples. In addition, Cu¹⁺ ions linked to the oxygen atoms of the glass framework were identified in ratios of about 60% and 30% of total copper in orange and red/brown samples, respectively. In blue and green samples, copper is dispersed in the glass matrix as a mixture of Cu¹⁺ and Cu²⁺ ions, and no crystalline phases are visible. In this context, the Cu¹⁺ and Cu²⁺ contents in glass were also quantified thanks to suitable standards, demonstrating that, when Cu²⁺ is the main chromophorous ion, colour intensity is directly correlated to its content in the glass. In particular, in green and blue samples, coloured by copper, Cu²⁺ content varies from 26% to 56% of total copper, and the higher contents of Cu²⁺ are shown by more intensely coloured samples. It should be stressed here that the green colour of the analysed tesserae is given by the physical interaction of blue colour, due to Cu²⁺ ions, and yellow colour, due to Pb antimonates used as opacifiers.  相似文献   

The system of thematic classification of an integrated databank of geological research considering polydisciplinarity     

D. A. Kuz’mina 《Scientific and Technical Information Processing》2010,37(3):207-216

Questions about the construction of linguistic tools of an integrated databank on geology on a unified basis considering the polydisciplinarity and comparison of generally adopted information retrieval languages are examined. A system model of thematic classification for the integration of heterogeneous geological information on the basis of research problems is offered. Using the example of the common rubricators at the bibliographic (VINITI rubricator of the Russian Academy of Sciences) and factographic levels (VSEGEI dictionaries) generalized models are presented, viz., the organization of a thematic polydisciplinary space, the integration of geoecological data, and the thematic classifications of radiogeological data, volcanic danger, and mineralogical-planetological subjects.  相似文献   

Can ‘pooling teaching tips’ be more than ‘pooling teaching tips’?     

Colin O’Byrne  Gwynaeth McIntyre  Celia Lie  Sheena Townsend  Benjamin Schonthal 《Tertiary Education and Management》2013,19(4):351-361

Abstract

There is increasing interest in how academic development of various kinds influences university teaching and student learning. To date the focus has been on formal, expert-led opportunities to learn how to teach. Our institution has developed a less formal, participant-led forum for teaching staff that was initially established to share ideas on teaching techniques and skills. We report here on participant-led research that explores if and how this model of group learning works, and how it might relate to other models that have been applied to tertiary teaching development. Authors adopted a self-study research framework incorporating a collaborative autoethnography. The data emphasises how participants use this forum as a community of practice, as a means for deep engagement with learning about teaching, and as a means to rationally manage their learning against a backdrop of challenges associated with learning to teach in research-led higher education.  相似文献   

Do perceptions of being treated fairly increase students’ outcomes? Teacher–student interactions and classroom justice in Italian adolescents     

Luisa Molinari  Giuseppina Speltini  Stefano Passini 《Educational Research and Evaluation》2013,19(1):58-76

In this study, we have investigated the associations between the students’ perceptions of teachers’ interpersonal behaviour and some school outcomes – namely, academic achievement, learning motivation, and a sense of class belonging – considering the mediating role of classroom justice. Moreover, the impact of the school type was analysed. The research was performed on a population of 614 Italian students enrolled in 2 different types of secondary school, one with an academic orientation, the other with a vocational orientation. Structural equation modelling (SEM) was used to see the effect of the teachers’ behaviour on the dimensions of justice (i.e., equality, equity, needs, and interpersonal) and that of all these variables on academic achievement, learning motivation, and class belonging. The mediation role of classroom justice was confirmed by the analyses, and so was the impact of the school's orientation. Limitations to the study and future research ideas have also been outlined.  相似文献   

Faculty integration of technology in teacher preparation: outcomes of a development model     

Sharon Judge  Blanche O’Bannon 《Technology, Pedagogy and Education》2013,22(1):17-28

This article reports on a faculty development model that uses a variety of approaches and strategies to help faculty restructure their curricula and effectively model technology integration for their students. A multifaceted model, funded in part by the Preparing Tomorrow’s Teachers to Use Technology (PT3) initiative, was implemented at The University of Tennessee, Knoxville. The model included training, technical and collegial support, access, and incentives. Questionnaires and qualitative data indicated substantive changes in faculty expectations and assumptions regarding technology as well as increases in faculty and student technology skills and the degree to which faculty members integrate technology into their curricula. The model helped to facilitate the collaborative efforts of a cadre of faculty to model and integrate technology throughout their teacher preparation programs.  相似文献   

Tongan secondary students’ conceptions of schooling in New Zealand relative to their academic achievement     

Mo’ale ‘Otunuku  Gavin T. L. Brown  Airini 《Asia Pacific Education Review》2013,14(3):345-357

This study examines the relationship between Tongan students’ attitudes and beliefs towards their school experiences and their academic achievement on the high-stakes National Certificate of Educational Achievement (NCEA) assessments in English and mathematics. Data were obtained from using previously published self-reported inventories on a sample of Tongan senior students in New Zealand secondary schools. Confirmatory factor analysis of students’ conceptions found good fit measurement models for each domain (teaching, learning, and assessment). Structural equation modelling was used to identify the effect of the various beliefs upon students’ total score in each subject and upon internal and externally assessed performance. It was noted that different beliefs became statistically significant predictors of performance, depending on the subject and type of assessment. Nonetheless, all three constructs played some role in at least one subject. A small-to-moderate proportion of variance in NCEA performance could be attributed to student beliefs, suggesting that efforts to help students adopt adaptive beliefs will have beneficial consequences for those students.  相似文献   

The Influence of Criminal Justice Major on Punitive Attitudes     

Tara O’Connor Shelley  Courtney A. Waid  Rhonda R. Dobbs 《Journal of Criminal Justice Education》2013,24(4):526-545

Students majoring in criminology and criminal justice are assumed to have more detailed and accurate knowledge about crime, criminal justice, and punishment practices than peers majoring in other disciplines. The purpose of this study was to examine if criminology/criminal justice majors were more or less punitive than students pursuing other majors at three universities using standard predictors of punitiveness that have not been consistently examined in previous research. The results indicate that criminology and criminal justice students are more punitive in the combined three‐campus sample and in two of the three‐campus samples considered separately.  相似文献   

Teaching gender and sexuality diversity in foundations of education courses in the US     

Michael O’Malley  Mei Hoyt 《Teaching Education》2013,24(2):95-110

This article is a summary of comprehensive units on gender and sexuality diversity that the authors have used in teacher education courses in undergraduate and graduate social foundations of education classes over several years. The course lesson plan includes a five‐part analysis of the following categories: biological sex; gender identity/sexual identity; gender roles; sexual behavior; and sexual orientation. The authors have experienced much success and positive student evaluation by using this approach. This is true even in religiously and politically conservative universities. The authors introduce the complexity of biology, gender roles, and gender identity, before addressing human sexuality. This helps to diffuse many stereotypes and misconceptions in the initial lessons.  相似文献   

Classroom behaviour management content in Australian undergraduate primary teaching programmes     

Sue O’Neill  Jennifer Stephenson 《Teaching Education》2013,24(3):287-308

The ability to differentiate classroom behaviour management (CBM) strategies is an important skill for novice teachers in increasingly diverse classrooms. Worldwide, little is known about the curriculum content offered to pre-service teachers in the area of CBM. This article reports the findings from the first nationwide survey of Australian primary pre-service teacher educators coordinating units and programmes with CBM content. Twenty-five Australian tertiary institutions with primary programmes participated, providing information on 102 of the 118 units with CBM content. Stand-alone units were offered in 68% of programmes and embedded in 96% of programmes. Unit coordinators included a mean of 8.3 approaches/models per unit. They commonly included applied behaviour analysis, decisive discipline, positive behaviour intervention and support, and choice theory/reality therapy, among the 36 approaches/models listed. More than half (57.9%) of the stand-alone units and only 20% of embedded units were coordinated by an academic with a stated CBM research interests. Units coordinated by an academic with CBM research interests contained more hours/model and included research-based models more often than those without CBM research interests, although they still included non-research-based models.  相似文献
