Information literacy is a mosaic of attitudes, understandings, capabilities and knowledge about which there are three myths. The first myth is that it is about the ability to use ICTs to access a wealth of information. The second is that students entering higher education are information literate because student centred, resource based, and ICT focused learning are now pervasive in secondary education. The third myth is that information literacy development can be addressed by library-centric generic approaches. This paper addresses those myths and emphasises the need for information literacy to be recognised as the critical whole of education and societal issue, fundamental to an information-enabled and better world. In formal education, information literacy can only be developed by infusion into curriculum design, pedagogies, and assessment.
Rawang [...] is a Tibeto-Burman language spoken by people who live in the far north of Kachin State in Myanmar (Burma), particularly along the Mae Hka ('Nmai Hka) and Maeli Hka (Mali Hka) river valleys (see map on back page); population unknown, although Ethnologue gives 100,000. In the past they had been called ‘Nung’, or (mistakenly) ‘Hkanung’, and are considered to be a sub-group of the Kachin by the Myanmar government. Until government policies put a stop to the clearing of new land in 1994, the Rawang speakers still practiced slash and burn farming on the mountainsides (they still do a bit, but only on already claimed land), in conjunction with planting paddy rice near the river. They are closely related to people on the other side of the Chinese border in Yunnan classified as either Dulong or Nu(ng) (see LaPolla 2001, 2003 on the Dulong language). In this paper, I will be discussing the word-class-changing constructions found in Rawang, using data of the Mvtwang (Mvt River) dialect of Rawang, which is considered the most central of those dialects in Myanmar and so has become something of a standard for writing and inter-group communication.
The paper presents a study which was based on the hypothesis that wikis that are initiated bottom up by students might be used more deliberately than wikis which are introduced top down by teachers. Therefore it examines the specific effects observed in nine different wiki projects at the university of Frankfurt ranging from student wiki projects up to wikis used in seminars and as information tool for institutions.
The fear that with the existence of an unconditional basic income sufficient for living many people would cease to engage in a productive life, would only relax, consume and devote to having fun, can be addressed from different perspectives. One of these is the sociology of religion, which allows elaborating the argument that with such a way of life the question about the meaning of life cannot be answered. But this "meaning question", the whole research within the field of the sociology of religion speaks for this, compellingly must be answered by each life praxis. It cannot remain unanswered, as is said already in the Bible: "Man does not live on bread alone, [but on every word that comes from the mouth of God.]" (5. Moses 8.3, Matthew 4.4, Lukas 4.4) The paper examines the reasons of this fact and its consequences in regard to a life with an unconditional basic income sufficient for living.
This paper shows that several typologically unrelated languages share the tendency to avoid voiced sibilant affricates. This tendency is explained by appealing to the phonetic properties of the sounds, and in particular to their aerodynamic characteristics. On the basis of experimental evidence it is shown that conflicting air pressure requirements for maintaining voicing and frication are responsible for the avoidance of voiced affricates. In particular, the air pressure released from the stop phase of the affricate is too high to maintain voicing, which in consequence leads to a devoicing of the frication part.
The recognition of pharmacological substances, compounds and proteins is an essential preliminary work for the recognition of relations between chemicals and other biomedically relevant units. In this paper, we describe an approach to Task 1 of the PharmaCoNER Challenge, which involves the recognition of mentions of chemicals and drugs in Spanish medical texts. We train a state-of-the-art BiLSTM-CRF sequence tagger with stacked Pooled Contextualized Embeddings, word and sub-word embeddings using the open-source framework FLAIR. We present a new corpus composed of articles and papers from Spanish health science journals, termed the Spanish Health Corpus, and use it to train domain-specific embeddings which we incorporate in our model training. We achieve a result of 89.76% F1-score using pre-trained embeddings and are able to improve these results to 90.52% F1-score using specialized embeddings.
In this increasingly complex world of learned information delivery and discovery - is it possible that the "free lunch" the Publishing world worries about could come true? Although Open Access and Institutional Repositories have not (yet) created the "scorched earth" effect many were predicting, they are slowly and inevitably gaining momentum. Broader access to top-level information via Google (and others) does indeed appear to be "good enough" for many in their search for content. But you rarely get food for free in a good quality restaurant. You pay for the selection, preparation, speed and expertise of the delivery. At the soup kitchen the food can often be filling - but the queue will be long, the wait even longer and there is no chance of silver service or à la carte. If you are unfortunate enough to have little choice then this may be a great solution. Others will be willing to pay for a more satisfactory meal. As in all aspects of life, diversification and specialisation are fundamental forces. The publishing community in the years to come will continue to develop its offerings for a variety of needs that require more than just broth. To stretch the analogy, the ongoing presence of tap water in our lives has done little to halt the extraordinary rise of bottled water as part of our staple diet. Business reality will continue to settle these types of debate; my bet is that the commercial publishers see a role as providing information that commands an intrinsic value proposition to enough customers to remain economically viable for some time to come. Inspired by the comments and ideas expounded by Dr. James O'Donnell of Georgetown University on the liblicense listserv on 20th July this year, this paper will look to expand on the analogy and identify the good, the bad - but importantly the difference in information quality and access that will result in the radically changed (but still co-existent) information landscape of tomorrow.
