This issue is a tribute to Har Gobind Khorana who received the Nobel Prize in Physiology or Medicine in 1968 for the elucidation of the Genetic Code. Here we present our view of the changing and ever-challenging perception of the genetic code over the last 50 years. 相似文献

Abstract The central purpose of this study was to determine the origin of sports extant in English-speaking countries. The method of research utilized was principally historical-bibliographical and was concerned with the collection, criticism, and synthesis of source material in an effort to establish past actuality. Specific documentary evidence concerning the date, place, and significant circumstances associated with the origins of 95 sports was synthesized. In most instances, establishing the date and place of origin was possible. Often, however, determining the personnel and circumstances connected with the origins was not possible. Charts show the dates of the origins chronologically, the origins attributed to various countries, and the activities from which the 95 sports evolved. 相似文献

The authors are concerned that, on one hand, the public universities in the United Kingdom and in other developed countries are becoming increasingly overcrowded (massified) and, on the other hand, underfunded. At the same time, numerous students who have had, in many cases, to pay large sums of money for their education, as in Canada, cannot find jobs when they graduate. Yet, increasingly, large corporations are creating in‐house training programmes and, in some cases, corporate universities. The conclusion is that academe is not providing the trained personnel that industry wishes (and needs) to hire. Why are universities apparently unable to fill the gap? A solution would be more targeted governmental steering of higher education. However, the majority of job creators in technological societies are small‐ and medium‐size enterprises. They cannot create their own training programmes, much less their own corporate universities. They must rely on higher education institutions both to provide them with skilled personnel with initial qualifications and then to provide further training. Higher education must seize this potential market. 相似文献

As an emerging field within higher education, academic development remains fragmented, both as a field of theory and practice. In the vibrant, on-going debate about the theoretical foundations and directions of academic development as a nascent field, some relatively wide-ranging claims which have been made seem to be lacking in supporting empirical evidence. With regards to this limitation, this paper contends that more systematic empirical explorations of the knowledge-base of academic development are vital to gain a better understanding of the field. Informed by Bernstein’s social realist frameworks on the structure of academic knowledge, the paper presents an analysis of knowledge recontextualisation processes in two English and two Flemish academic development units, based on semi-structured interviews with 30 academic developers. From the analysis, contrasting patterns of knowledge recontextualisation emerged between the four sites and between the national contexts in particular, pointing towards an increasing epistemological fragmentation. 相似文献

The Achievements of Deaf Pupils in Scotland (ADPS) project has been tracking the educational attainment of deaf pupils in Scotland's schools since 2000. At the time of writing, the database contains records for 1,752 deaf pupils (2000-2005). Here 4-year aggregate educational attainment data are reported for a subset of 152 school-aged deaf pupils with cochlear implants notified to the ADPS database between June 2000 and June 2004. The data describe primary and secondary school results in reading, writing, and math for this subgroup, as well as placement and communication characteristics. The educational attainment of the group of deaf pupils with cochlear implants is clearly marked when the deaf pupil population is disaggregated for hearing loss, achieving comparatively higher average attainment in both 5-14 Curriculum National Tests (Mathematics in particular) and Standard Grades. Therefore the gap in performance relative to the national population data is reduced for those deaf pupils, although it still widens at higher levels of achievement for the National Tests. Although most pupils with cochlear implants are placed in the mainstream, there is no pattern of migration toward mainstream schools. Some deaf pupils with cochlear implants moved out of mainstream to other types of placement, and this has implications for health-economic cost-utility assessments of cochlear implantation that favor mainstream education by drawing upon the relative cost of different placement types. These findings suggest that the ADPS program of research can contribute school outcome data as valuable real-life outcome measures in wider assessments of the benefit of cochlear implants to deaf children and deaf young people. 相似文献

The impact of new public management instruments on PhD education 总被引:1,自引:0,他引:1
New public governance emphasises less state, more market and more hierarchy as the cornerstones for effective steering of
higher education institutions. Based on an explorative analysis of qualitative and quantitative data of fourteen German and
European economics departments, we investigate the steering effects of six new public management instruments in the years
2001 and 2002 on subsequent placement success of PhD graduates. Using crisp set Qualitative Comparative Analysis to analyse
the data, our results deliver strong support for the positive effects of competition for resources and the varying effects
of hierarchy on PhD education. Governance of successful departments is characterised by two solutions: transparency over academic achievements as one single success factor in each solution or a combination of additional
funding based on national competitive performance with either no
public policy regulations for departments or no
university regulations for departments. Governance of unsuccessful departments is characterised by one solution: university
regulations for departments or a combination of no
additional
funding based on national
competitive performance and no
transparency over academic achievements. Our results strengthen the strong impact of selected competitive mechanisms as an effective governance instrument and the
partially detrimental effects of state regulations. University regulations turn out to be successful if they increase transparency
over academic achievements by faculty members. Success is unlikely if those rules intervene into PhD education. 相似文献

TIJAH: Embracing IR Methods in XML Databases 总被引:1,自引:0,他引:1
Johan?ListEmail author Vojkan?Mihajlovi? Georgina?Ramírez Arjen?P.?de?Vries Djoerd?Hiemstra Henk?Ernst?Blok 《Information Retrieval》2005,8(4):547-570
This paper discusses our participation in INEX (the Initiative for the Evaluation of XML Retrieval) using the TIJAH XML-IR system. TIJAHs system design follows a standard layered database architecture, carefully separating the conceptual, logical and physical levels. At the conceptual level, we classify the INEX XPath-based query expressions into three different query patterns. For each pattern, we present its mapping into a query execution strategy. The logical layer exploits score region algebra (SRA) as the basis for query processing. We discuss the region operators used to select and manipulate XML document components. The logical algebra expressions are mapped into efficient relational algebra expressions over a physical representation of the XML document collection using the pre-post numbering scheme. The paper concludes with an analysis of experiments performed with the INEX test collection. 相似文献
