The Archaeology of Pouerua
No full textThe Archaeology of the Pouerua is an important book in Pacific archaeology, the third and major book to emerge from the Pouerua Project, which was a major archaeological initiative of the 1980s, studying the extensive pa (native village) site on and around the volcanic cone at Pouerua, Northland, New Zealand. AUP has previously published two small books from this research, The Archaeology of the Kainga and The Archaeology of the Peripheral Pa. These are fairly technical studies but the first in particular has been used as a text and has sold very well. This crowning volume, The Archaeology of Pouerua, is a much larger book than the previous two. It studies the pa itself and the innovative attempt to use archaeological techniques to explore and understand socio-political process. The investigation revealed the pa as a fluid site with different functions changing over time; not a place of permanent settlement but rather a visible sign of power and dominance. The text is not aimed at a general readership but will be of detailed interest to researchers, teachers and students. Contents1. Pouerua and Pa Site Archaeology 2. Pouerua and the Pouerua Project 3.

Incidence and outcome of persons with a clinical diagnosis of heart failure in a general practice population of 696,884 in the United Kingdom
No full textBackground: There are few large population-based studies of the incidence and outcome of heart failure where the diagnosis of heart failure
(HF) has been made by a General Practitioner (GP) in the community.
Methods: From the General Practice Research Database in the UK, we selected a population of 686,884 people 45 years or older. Incident
cases of HF in 1991 were classified definite HF, possible HF, or a first prescription of diuretics without a diagnosis of HF. The population was
followed for 3-year mortality.
Results: A total of 6478 patients had definite HF (mean age 77.2 years, 55.5% women), 14,050 had possible HF and 6076 persons were
prescribed diuretics without a definite or possible diagnosis of HF. The overall incidence of definite HF was 9.3/1000 persons/year and of
possible HF 20.2/1000 persons/year. Diuretics were prescribed for the first time for other reasons for 8.7 persons/1000/year. The incidence of
HF was higher in men. The incidence of definite HF increased with age. Survival curves showed higher mortality rates in the first 3 months
after the diagnosis of HF. One-year cumulative probability of death for patients with definite HF was 15.9 times higher in men and 14.7 times
higher in women in comparison with the UK population.
Conclusion: The diagnosis of HF by a GP successfully identifies patients at high risk of death, comparable to patients with HF identified by
cardiologists on the basis of defined diagnostic criteria. HF is common in the general population, increases sharply with age, and has a poor
prognosis

South African responses to Open Access publishing: a survey of the research community
Get PDFOpen access publishing offers wide benefits to the scholarly community and may also afford relief to financially embattled academic libraries. The progress of the open access model rests upon the acceptance and validation of open access journals and open archives or institutional repositories by the academic mainstream, particularly by publishing researchers. To what extent are the key actors in the South African research system aware of the advantages of open access? This article reports on the findings of a recent survey undertaken to assess the current awareness, concerns and depth of support for open access amongst local researchers, research managers and policy makers in South Africa. The study focuses on issues of quality, article or author charges and the established academic reward system. It concludes that within the prevailing framework, there is little prospect that academics would choose to publish within open access
journals. Recommendations for advocacy by the library community are proposed
Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
Get PDFIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)

Open access self-archiving: An author study
No full textThis, our second author international, cross-disciplinary study on open access had 1296 respondents. Its focus was on self-archiving. Almost half (49%) of the respondent population have self-archived at least one article during the last three years. Use of institutional repositories for this purpose has doubled and usage has increased by almost 60% for subject-based repositories. Self-archiving activity is greatest amongst those who publish the largest number of papers. There is still a substantial proportion of authors unaware of the possibility of providing open access to their work by self-archiving. Of the authors who have not yet self-archived any articles, 71% remain unaware of the option. With 49% of the author population having self-archived in some way, this means that 36% of the total author population (71% of the remaining 51%), has not yet been appraised of this way of providing open access. Authors have frequently expressed reluctance to self-archive because of the perceived time required and possible technical difficulties in carrying out this activity, yet findings here show that only 20% of authors found some degree of difficulty with the first act of depositing an article in a repository, and that this dropped to 9% for subsequent deposits. Another author worry is about infringing agreed copyright agreements with publishers, yet only 10% of authors currently know of the SHERPA/RoMEO list of publisher permissions policies with respect to self-archiving, where clear guidance as to what a publisher permits is provided. Where it is not known if permission is required, however, authors are not seeking it and are self-archiving without it. Communicating their results to peers remains the primary reason for scholars publishing their work; in other words,
researchers publish to have an impact on their field. The vast majority of authors (81%) would willingly comply with a mandate from their employer or research funder to deposit copies of their articles in an institutional or subject-based repository. A further 13% would comply reluctantly; 5% would not comply with such a mandate
A Millimeter-Wave Front-End for FD/FDD Transceivers Featuring an Embedded PA and an N-Path Filter Based Circulator Receiver
No full textThis work presents an ultra-compact single-antenna FD/FDD transceivers front-end. It comprises a nonreciprocal circulator, RX, and an integrated power amplifier (PA). In the proposed circulator, we devise a ring quarter-wave transmission line topology with adjusted characteristic impedances to improve TX-to-antenna insertion loss and TX-to-RX isolation. Besides, an AND-gate switching-based N-path filter is proposed to realize the circulator's nonreciprocal gyrator while acting as a mixer-first RX. Owing to the ultra-compact N-path filter structure, the circulator occupies only 0.38mm 2 core area. Over a 27.1-to-31.1GHz band, the realized front-end offers >20dB TX-to-RX isolation while its measured TX-to-antenna insertion loss is 1.7~2.2dB. The RX path tolerates the PA's blocker signal, achieving 5dBm in-band and 13dBm out-of-band B 1dB. Moreover, the PA delivers 15.15dBm peak output power with 33% drain efficiency. Our front-end prototype occupies only 0.7mm 2 , including circulator, PA, quadrature hybrid coupler LO generators, and baseband circuits.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Electronic
