South African responses to Open Access publishing: a survey of the research community
No full textOpen 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
No full textIn 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
Vrednotenje inovacijskega sistema v MSP z uporabo razvrščanja in tehtanja pomena inovacij
No full textIn this bachelor thesis, the different types of innovation within a company are studied and analysed. The companies studied are SMEs i.e. from 10 to 250 employees. Smaller companies are mainly confronted with the problem of resources and larger companies with their strategic orientation. We have studied the ten types of innovations according to Doblin (Doblin 2014), and we realise that they have a rather marketing-oriented focus, so we analyse five groups of innovations that we consider to be the key (marketing, product, organisational, business model and technological innovation). Five groups of innovations have been weighed on a scale from 0 to 100 % according to their importance to contribute to the economic success of the company. All groups have been weighted and ranked in order of priority to initiate the innovation process in the SME, starting with marketing, followed by product, technological, organisational and business model innovations. We found innovation process needs to be implemented as a continuous cyclical process. If the company wants to be successful, it is a continuous cycle model, which should never stop. Once a particular innovation is chosen, it will be studied and tested whether the investment can be successful. If so investment process will be executed, if not, the cycling process will start again until gives a positive result. This way one of the innovation is recognized as most important according to circumstances in SME involved at a certain moment.V predstavljeni diplomski nalogi preučujemo in analiziramo procese inoviranja v majhnih in srednjih podjetjih. Preučujemo majhna in srednja podjetja (MSP) to so podjetja, ki zaposlujejo od 10 do 250 ljudi. Podjetja na spodnji meji (manjša podjetja) se v glavnem soočajo s problemom virov, večja pa s svojo strateško usmeritvijo. Preučili smo deset vrst inovacij, ki jih je opredelil Doblin (Doblin 2014) in spoznali, da so usmerjene predvsem v marketinške aktivnosti. Tako smo analizirali še druge skupine inovacij, za katere menimo, da so ključne (marketinške, izdelčne, organizacijske, inovacije poslovnih modelov in tehnološke inovacije). Spoznanih pet skupin inovacij smo razvrstili po metodi tehtanja pomena na lestvici od 0 do 100 % glede na njihov pomen pri prispevanju k gospodarskem uspehu podjetja. Vse skupine so bile ponderirane in razvrščene po prednostnem vrstnem redu, da prikažejo potek procesa inoviranja v MSP, začenši s trženjem, sledijo inovacije izdelkov, tehnološke inovacije ter organizacijske in inovacije poslovnih modelov. Ugotovili smo, da je potrebno inovacijski postopek izvajati kot stalen ciklični proces, ki se ne sme ustaviti. V kolikor želi biti podjetje uspešno je potrebno model inoviranja neprekinjeno izvajati v smislu cikličnega vračanja ali povratne zanke takrat, ko smo preverili ali je ena od inovacij ovrednotena kot primerna za investiranje. Ko je določena inovacija izbrana, jo je potrebno preveriti kot investicijo ali obeta ugodne rezultate ali ne. V primeru pozitivnih rezultatov se lahko naložbeni postopek izvede, v nasprotnem primeru se ciklični proces vrne na začetek in pričnemo obravnavati inovacije znova. Cikliranje skozi inovacijske skupine se ponavlja dokler ne ugotovimo, da je določena inovacija tista, ki jo iščemo. Tako je ena od inovacij prepoznana kot najpomembnejša glede na okoliščine, ki vladajo v danem trenutku v MSP. Model cikličnega procesa je pregleden in nudi učinkovito metodo za pričetek izvajanja inovacijskega procesa v MSP

An Auto-Zero-Stabilized Voltage Buffer With a Quiet Chopping Scheme and Constant Sub-pA Input Current
No full textThis article describes an auto-zero stabilized voltage buffer that achieves low offset and low noise with sub-pA input current. A high gain stabilization loop is used to periodically cancel the buffer’s offset. The loop itself is periodically disconnected from the buffer and auto-zeroed, during which its bandwidth is reduced to reduce the associated noise folding. However, this also reduces its offset correction range, and so to avoid overloading, its initial offset is digitally trimmed. To break up the correlation between the residual low-frequency (LF) noise of the auto-zero and stabilization phases, the loop is periodically chopped, which significantly reduces the buffer’s LF noise. Finally, the duty-cycle of the two phases is optimized to bring the buffer’s LF noise density close to 2–√ times its white noise density (14 nV/ Hz−−−√ ), which is the fundamental limit of an AZ amplifier. The buffer also achieves a constant and low input current (0.8 pA), as well as a state-of-the-art offset (0.4 μV ).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 InstrumentationMicroelectronic
