Over the last decade industrial and academic communities have increased their focus on sentiment analysis techniques, especially applied to tweets. State-of-the-art results have been recently achieved using language models trained from scratch on corpora made up exclusively of tweets, in order to better handle the Twitter jargon. This work aims to introduce a different approach for Twitter sentiment analysis based on two steps. Firstly, the tweet jargon, including emojis and emoticons, is transformed into plain text, exploiting procedures that are language-independent or easily applicable to different languages. Secondly, the resulting tweets are classified using the language model BERT, but pre-trained on plain text, instead of tweets, for two reasons: (1) pre-trained models on plain text are easily available in many languages, avoiding resource- and time-consuming model training directly on tweets from scratch; (2) available plain text corpora are larger than tweet-only ones, therefore allowing better performance. A case study describing the application of the approach to Italian is presented, with a comparison with other Italian existing solutions. The results obtained show the effectiveness of the approach and indicate that, thanks to its general basis from a methodological perspective, it can also be promising for other languages.

Hadoop MapReduce reactively detects and recovers faults after they occur based on the static heartbeat detection and the re-execution from scratch techniques. However, these techniques lead to excessive response time penalties and inefficient resource consumption during detection and recovery. Existing fault-tolerance solutions intend to mitigate the limitations without considering critical conditions such as fail-slow faults, the impact of faults at various infrastructure levels and the relationship between the detection and recovery stages. This paper analyses the response time under two main conditions: fail-stop and fail-slow, when they manifest with node, service, and the task at runtime. In addition, we focus on the relationship between the time for detecting and recovering faults. The experimental analysis is conducted on a real Hadoop cluster comprising MapReduce, YARN and HDFS frameworks. Our analysis shows that the recovery of a single fault leads to an average of 67.6% response time penalty. Even though the detection and recovery times are well-turned, data locality and resource availability must also be considered to obtain the optimum tolerance time and the lowest penalties.

The paper presents the results of tests of wear of hardened wear-resistant steels in the presence of quartz, coal and coal-mineral abrasives of a differentiated ratios of each component and in the case without abrasives. The tests were carried out on a ring-on-ring test stand. Volume loss was the parameter used to characterize the wear level. Based on the Scanning Electron Microscopy (SEM) observations, different mechanisms of surface destruction depending on the type of abrasive were found. For the quartz abrasive, it was shown that the quartz grains cause micro-cutting, but surface cracks also appear that further transform into shallow holes. In the case of mixtures of quartz with coal, the surface was micro-scratched by quartz grains, but some of these grains were hammered into the surface, what was favoured by the presence of coal fractions. In the case of coal abrasive, traces of single cutting were observed, as well as unremoved scratches formed at the sample grinding stage. Based on the wear observation, two models of steel surface wear in the presence of coal and coal-mineral abrasives were determined.

How group housed sows are managed can have an impact on their welfare during gestation. The present study examined the effects of housing management (static vs. dynamic), stage of gestation at introduction, familiarity within the group, and age of sow on some aspects of the behaviour and physiology of sows in an electronic sow feeding system. Eight groups were introduced into either a static or dynamic management system. Within an introduction group, 21 to 23 focal sows were selected based upon their stage of gestation (pre vs. post-implantation), familiarity with groupmates (familiar vs. unfamiliar) and parity [young (1st parity) vs. intermediate (2nd and 3rd parity) vs. old (4th parity and higher)]. The aggression at mixing, aggression at the feeder, injuries, feeder entry order, lying patterns, and salivary cortisol concentrations were recorded. There were no differences in the behaviour or physiology of sows housed in either housing management system, or based upon familiarity. Sows mixed post-implantation were less aggressive (P = 0.01), entered the feeding station later (P = 0.03) and were observed lying in the least preferred areas of the pen (P = 0.001), than sows grouped within a few days of breeding. Older sows were involved in more aggressive encounters (P = 0.04), spent more time fighting at mixing (P = 0.02), and lay against the wall more (P < 0.001) than did young sows, which tended to sustain more scratches (P = 0.07), and ate later in the feed cycle (P < 0.001). A dynamic management system is just as effective as a static management system when certain management criteria are met. Familiarity does not have an impact on the sows during gestation. Stage of gestation and parity should be considered along with the group dynamic as it can impact aggression and access to resources. Key words: Sows, gestation, electronic sow feeding system, behaviour

Computational Thinking (CT) is a set of logical-operational cognitive skills or processes of reasoning, based on Computer Science. Abstraction, pattern recognition, algorithmic reasoning, and decomposition are examples of some of these skills that form the four pillar of CT. Some researchers have considered these skills as useful, and even mandatory to to cognitive development of the schoolchildren. In this paper, we present practical aspects and the possible contributions of CT in the development of competence of reading and interpreting English texts. Didactic interventions were carried out in high school classes of a public school, supported by the Bring Your Own Device (BYOD) approach, in which the students used their own smartphones. During these interventions, the students developed concept maps and podcasts, performed online exercises and the traditional exam, all of that composed the set of evaluation instruments. It was possible to understand that the CT skills are intrinsically present and contributed to the development of the reading and writing skills in English. According to testimonials, we highlight that the BYOD approach provided new conceptions and perspectives on the use of electronic equipment in function of the students’ learning.ResumoO Raciocínio Computacional (RC) é um conjunto de habilidades ou processos cognitivos lógico-operacionais de raciocínio, fundamentadas na Ciência da Computação. Abstração, reconhecimento de padrões, raciocínio algorítmico e decomposição são exemplos de algumas dessas habilidades que formam os quatro pilares do RC. Alguns pesquisadores consideram essas habilidades úteis, e até mesmo fundamentais, para o desenvolvimento cognitivo dos estudantes. Nesse sentido, este relato de experiência tem por objetivo apresentar aspectos práticos e possíveis contribuições do RC no desenvolvimento da competência de leitura e interpretação de textos de diferentes naturezas na disciplina de língua inglesa. Para isso, realizaram-se intervenções didáticas em uma turma do ensino médio de uma escola pública, apoiadas na abordagem Bring Your Own Device ou, simplesmente, BYOD, em que os estudantes usaram seus próprios aparelhos celulares. Durante o desenvolvimento das intervenções, os estudantes construíram mapas conceituais e podcasts, realizarem exercício online e a tradicional prova, os quais compuseram o conjunto de instrumentos avaliativos do bimestre. Por meio dessas intervenções, foi possível identificar como as habilidades do RC estiveram intrinsecamente presentes e contribuíram para o desenvolvimento da competência de leitura e escrita em língua inglesa, elencada pelos Parâmetros Curriculares Nacionais. Conforme relatos, além da articulação didática com o RC, a abordagem BYOD proporcionou à professora e aos estudantes novas concepções e perspectivas sobre o uso de equipamentos eletrônicos em função da aprendizagem deles mesmos.Palavras-chave: Raciocínio computacional, Ensino de inglês, Mobile learning, Educação em computação.Keywords: Computational thinking, English teaching, Mobile learning, Computer science education.ReferencesALBERTA Education.

Here is the first issue of the new journal, Acta Linguistica Asiatica, published by the Department of Asian and African Studies, Faculty of Arts, University of Ljubljana. Its appearance is approximately timed to commemorate the 15 years since the establishment of the Department on October 1st, 1995. In step with the developments in media and new modes of dissemination of the results of scholarly research, it is introduced as an on-line electronic publication.In the past 15 years, Asian Studies which were initially represented by Chinese and Japanese Studies, seem to have established a firm foothold in Slovenia. In addition to the existing Chinese Studies and Japanese Studies, the University of Ljubljana introduced in December 2010 new academic areas of Turkish Studies, Iranian Studies, Indian Studies and Korean Studies, thus giving green light to the establishment of systematic research of Asian issues within a wider framework.In the meantime, the body of researchers specializing in Asian languages has also grown, including teachers, visiting professors, researchers and graduate students who cover a wide spectrum of research fields.Also, the recent reform of higher education along the Bologna guidelines, although criticized, has happily brought into existence the interdisciplinary Doctoral Program in Humanities and Social Sciences and within its fold, the joint Doctoral program in Linguistics.The Journal Acta Linguistica Asiatica is thus emerging in a period of lively ferment, where unifying the field of discourse within language studies and at the same time opening it more widely to research in humanities and social sciences will undoubtedly have a long term impact on Asian language research at the University of Ljubljana.Serving as a focal point of research on Asian languages in Slovenia, Acta Linguistica Asiatica will at the same time strive to promote cooperation in the field of Asian language research internationally in Europe, Asia and beyond. Acta Linguistica Asiatica will, following Roman Jakobson’s saying, “Linguista sum, linguistici nihil a me alienum puto”, cover all the subject areas and theoretical approaches pertaining to theoretical and applied research on Asian languages. An international editorial board takes care of the research quality of the journal.The contents of the first issue reflect this orientation and openness. Three papers deal with various aspects of the role played by language in the process of modernization during and after Meiji Japan, i.e., The Relation Between the View on the Language and Educational Ideology in the Early Meiji Period in Japan Through the Discourse of Regionalism by Ichimiya Yufuko, Towards Theoretical Approach to the Understanding of Language Ideologies in Post-Meiji Japan by Luka Culiberg, and Images of Pre-WW II: National Language Policies as Reflected in the Field of “National Language Studies” Itself by Andrej Bekeš.Another focus of interest is philological, represented by two papers. One is Morphology and Syntax in Holes and Scratches: The Latest Stage of Kugyol Research, an interesting research on kugyol, a system devised to facilitate reading Chinese Buddhist texts in Korean, by Lee Yong. The other,The Typology of Āmreḍita Compounds in the Ṛgveda by Tamara Ditrich, investigates āmreḍita compounds in the Ṛgveda, a type of coordinative nominal constructions, closely related to dvandva compounds.Finally, this issue is concluded with the article Collocational Relations in Japanese Language Textbooks and Computer-assisted Language Learning Resources, by Irena Srdanović and deals with the teaching of collocations in modern Japanese, based on corpora.

The move from analog distribution to online digital delivery is common in the contemporary mediascape. Music is in the midst of an ipod driven paradigm shift (Levy), television and movie delivery is being reconfigured (Johnson), and newspaper and magazines are confronting the reality of the world wide web and what it means for business models and ideas of journalism (Beecher). In the midst of this change, the book publishing industry remains defiant. While embracing digital production technologies, the vast majority of book content is still delivered in material form, printed and shipped the old-fashioned way—despite the efforts of many technology companies over the last decade. Even the latest efforts from corporate giants such as Sony and Amazon (who appear to have solved many of the technical hurdles of electronic reading devices) have had little visible impact. The idea of electronic books, or e-books, remains the domain of geeky early adopters (“Have”). The reasons for this are manifold, but, arguably, a broader uptake of e-books has not occurred because cultural change is much more difficult than technological change and book readers have yet to be persuaded to change their cultural habits. Electronic reading devices have been around for as long as there have been computers with screens, but serious attempts to replicate the portability, readability, and convenience of a printed book have only been with us for a decade or so. The late 1990s saw the release of a number of e-book devices. In quick succession, the likes of the Rocket e-Book, the SoftBook and the Franklin eBookman all failed to catch on. Despite this lack of market penetration, software companies began to explore the possibilities—Microsoft’s Reader software competed with a similar product from Adobe, some publishers became content providers, and a niche market of consumers began reading e-books on personal digital assistants (PDAs). That niche was sufficient for e-reading communities and shopfronts to appear, with a reasonable range of titles becoming available for purchase to feed demand that was very much driven by early adopters. But the e-book market was and remains small. For most people, books are still regarded as printed paper objects, purchased from a bookstore, borrowed from a library, or bought online from companies like Amazon.com. More recently, the introduction of e-ink technologies (EPDs) (DeJean), which allow for screens with far more book-like resolution and contrast, has provided the impetus for a new generation of e-book devices. In combination with an expanded range of titles (and deals with major publishing houses to include current best-sellers), there has been renewed interest in the idea of e-books. Those who have used the current generation of e-ink devices are generally positive about the experience. Except for some sluggishness in “turning” pages, the screens appear crisp, clear and are not as tiring to read as older displays. There are a number of devices that have embraced the new screen technologies (mobileread) but most attention has been paid to three devices in particular—mainly because their manufacturers have tried to create an ecosystem that provides content for their reading devices in much the same way that Apple’s itunes store provides content for ipods. The Sony Portable Reader (Sonystyle) was the first electronic ink device to be produced by a mainstream consumers electronics company. Sony ties the Reader to its Connect store, which allows the purchase of book titles via a computer; titles are then downloaded to the Reader in the same way that an mp3 player is loaded with music. Sony’s most prominent competition in the marketplace is Amazon’s Kindle, which does not require users to have a computer. Instead, its key feature is a constant wireless connection to Amazon’s growing library of Kindle titles. This works in conjunction with US cellphone provider Sprint to allow the purchase of books via wireless downloads wherever the Sprint network exists. The system, which Amazon calls “whispernet,” is invisible to readers and the cost is incorporated into the price of books, so Kindle users never see a bill from Sprint (“Frequently”). Both the Sony Reader and the Amazon Kindle are available only in limited markets; Kindle’s reliance on a cellphone network means that its adoption internationally is dependent on Amazon establishing a relationship with a cellphone provider in each country of release. And because both devices are linked to e-bookstores, territorial rights issues with book publishers (who trade publishing rights for particular global territories in a colonial-era mode of operation that seems to ignore the reality of global information mobility (Thompson 74–77)) contribute to the restricted availability of both the Sony and Amazon products. The other mainstream device is the iRex Iliad, which is not constrained to a particular online bookstore and thus is available internationally. Its bookstore ecosystems are local relationships—with Dymocks in Australia, Borders in the UK, and other booksellers across Europe (iRex). All three devices use EPDs and share similar specifications for the actual reading of e-books. Some might argue that the lack of a search function in the Sony and the ability to write on pages in the Iliad are quite substantive differences, but overall the devices are distinguished by their availability and the accessibility of book titles. Those who have used the devices extensively are generally positive about the experience. Amazon’s Customer Reviews are full of positive comments, and the sense from many commentators is that the systems are a viable replacement for old-fashioned printed books (Marr). Despite the good reviews—which suggest that the technology is actually now good enough to compete with printed books—the e-book devices have failed to catch on. Amazon has been hesitant to state actual sales figures, leaving it to so-called analysts to guess with the most optimistic suggesting that only 30 to 50,000 have sold since launch in late 2007 (Sridharan). By comparison, a mid-list book title (in the US) would expect to sell a similar number of copies. The sales data for the Sony Portable Reader (which has been on the market for nearly two years) and the iRex iliad are also elusive (Slocum), suggesting that they have not meaningfully changed the landscape. Tellingly, despite the new devices, the e-book industry is still tiny. Although it is growing, the latest American data show that the e-book market has wholesale revenues of around $10 million per quarter (or around $40 million per year), which is dwarfed by the $35 billion in revenues regularly earned annually in the US printed book industry ("Book"). It’s clear that despite the technological advances, e-books have yet to cross the chasm from early adopter to mainstream usage (see IPDF). The reason for this is complex; there are issues of marketing and distribution that need to be considered, as well as continuing arguments about screen technologies, appropriate publishing models, and digital rights management. It is beyond the scope of this article to do justice to those issues. Suffice to say, the book industry is affected by the same debates over content that plague other media industries (Vershbow). But, arguably, the key reason for the minimal market impact is straightforward—technological change is relatively easy, but cultural change is much more difficult. The current generation of e-book devices might be technically very close to being a viable replacement for print on paper (and the next generation of devices will no doubt be even better), but there are bigger cultural hurdles to be overcome. For most people, the social practice of reading books (du Gay et al 10) is inextricably tied with printed objects and a print culture that is not yet commonly associated with “technology” (perhaps because books, as machines for reading (Young 160), have become an invisible technology (Norman 246)). E. Annie Proulx’s dismissive suggestion that “nobody is going to sit down and read a novel on a twitchy little screen. Ever” (1994) is commonly echoed when book buyers consider the digital alternative. Those thoughts only scratch the surface of a deeply embedded cultural practice. The centuries since Gutenberg’s printing press and the vast social and cultural changes that followed positioned print culture as the dominant cultural mode until relatively recently (Eisenstein; Ong). The emerging electronic media forms of the twentieth century displaced that dominance with many arguing that the print age was moved aside by first radio and television and now computers and the Internet (McLuhan; Postman). Indeed, there is a subtext in that line of thought, one that situates electronic media forms (particularly screen-based ones) as the antithesis of print and book culture. Current e-book reading devices attempt to minimise the need for cultural change by trying to replicate a print culture within an e-print culture. For the most part, they are designed to appeal to book readers as a replacement for printed books. But it will take more than a perfect electronic facsimile of print on paper to persuade readers to disengage with a print culture that incorporates bookshops, bookclubs, writing in the margins, touching and smelling the pages and covers, admiring the typesetting, showing off their bookshelves, and visibly identifying with their collections. The frequently made technical arguments (about flashing screens and reading in the bath (Randolph)) do not address the broader apprehension about a cultural experience that many readers do not wish to leave behind. It is in that context that booklovers appear particularly resistant to any shift from print to a screen-based format. One only has to engage in a discussion about e-books (or lurk on an online forum where one is happening) to appreciate how deeply embedded print culture is (Hepworth)—book readers have a historical attachment to the printed object and it is this embedded cultural resistance that is the biggest barrier for e-books to overcome. Although e-book devices in no way resemble television, print culture is still deeply suspicious of any screen-based media and arguments are often made that the book as a physical object is critical because “different types of media function differently, and even if the content is similar the form matters quite a lot” (Weber). Of course, many in the newspaper industry would argue that long-standing cultural habits can change very rapidly and the migration of eyeballs from newsprint to the Internet is a cautionary tale (see Auckland). That specific format shift saw cultural change driven by increased convenience and a perception of decreased cost. For those already connected to the Internet, reading newspapers online represented zero marginal cost, and the range of online offerings dwarfed that of the local newsagency. The advantage of immediacy and multimedia elements, and the possibility of immediate feedback, appeared sufficient to drive many away from print towards online newspapers.For a similar shift in the e-book realm, there must be similar incentives for readers. At the moment, the only advantages on offer are weightlessness (which only appeals to frequent travellers) and convenience via constant access to a heavenly library of titles (Young 150). Amazon’s Kindle bookshop can be accessed 24/7 from anywhere there is a Sprint network coverage (Nelson). However, even this advantage is not so clear-cut—there is a meagre range of available electronic titles compared to printed offerings. For example, Amazon claims 130,000 titles are currently available for Kindle and Sony has 50,000 for its Reader, figures that are dwarfed by Amazon’s own printed book range. Importantly, there is little apparent cost advantage to e-books. The price of electronic reading devices is significant, amounting to a few hundred dollars to which must be added the cost of e-books. The actual cost of those titles is also not as attractive as it might be. In an age where much digital content often appears to be free, consumers demand a significant price advantage for purchasing online. Although some e-book titles are priced more affordably than their printed counterparts, the cost of many seems strangely high given the lack of a physical object to print and ship. For example, Amazon Kindle titles might be cheaper than the print version, but the actual difference (after discounting) is not an order of magnitude, but of degree. For example, Randy Pausch’s bestselling The Last Lecture is available for $12.07 as a paperback or $9.99 as a Kindle edition (“Last”). For casual readers, the numbers make no sense—when the price of the reading device is included, the actual cost is prohibitive for those who only buy a few titles a year. At the moment, e-books only make sense for heavy readers for whom the additional cost of the reading device will be amortised over a large number of books in a reasonably short time. (A recent article in the Wall Street Journal suggested that the break-even point for the Kindle was the purchase of 61 books (Arends).) Unfortunately for the e-book industry, not is only is that particular market relatively small, it is the one least likely to shift from the embedded habits of print culture. Arguably, should e-books eventually offer a significant cost benefit for consumers, uptake would be more dramatic. However, in his study of cellphone cultures, Gerard Goggin argues against purely fiscal motivations, suggesting that cultural change is driven by other factors—in his example, new ways of communicating, connecting, and engaging (205–211). The few market segments where electronic books have succeeded are informative. For example, the market for printed encyclopedias has essentially disappeared. Most have reinvented themselves as CD-ROMs or DVD-ROMs and are sold for a fraction of the price. Although cost is undoubtedly a factor in their market success, added features such as multimedia, searchability, and immediacy via associated websites are compelling reasons driving the purchase of electronic encyclopedias over the printed versions. The contrast with the aforementioned e-book devices is apparent with encyclopedias moving away from their historical role in print culture. Electronic encyclopedias don’t try to replicate the older print forms. Rather they represent a dramatic shift of book content into an interactive audio-visual domain. They have experimented with new formats and reconfigured content for the new media forms—the publishers in question simply left print culture behind and embraced a newly emerging computer or multimedia culture. This step into another realm of social practices also happened in the academic realm, which is now deeply embedded in computer-based delivery of research and pedagogy. Not only are scholarly journals moving online (Thompson 320–325), but so too are scholarly books. For example, at the Macquarie University Library, there has been a dramatic increase in the number of electronic books in the collection. The library purchased 895 e-books in 2005 and 68,000 in 2007. During the same period, the number of printed books purchased remained relatively stable with about 16,000 bought annually (Macquarie University Library). The reasons for the dramatic increase in e-book purchases are manifold and not primarily driven by cost considerations. Not only does the library have limited space for physical storage, but Macquarie (like most other Universities) emphasises its e-learning environment. In that context, a single e-book allows multiple, geographically dispersed, simultaneous access, which better suits the flexibility demanded of the current generation of students. Significantly, these e-books require no electronic reading device beyond a standard computer with an internet connection. Users simply search for their required reading online and read it via their web browser—the library is operating in a pedagogical culture that assumes that staff and students have ready access to the necessary resources and are happy to read large amounts of text on a screen. Again, gestures towards print culture are minimal, and the e-books in question exist in a completely different distributed electronic environment. Another interesting example is that of mobile phone novels, or “keitai” fiction, popular in Japan. These novels typically consist of a few hundred pages, each of which contains about 500 Japanese characters. They are downloaded to (and read on) cellphones for about ten dollars apiece and can sell in the millions of copies (Katayama). There are many reasons why the keitai novel has achieved such popularity compared to the e-book approaches pursued in the West. The relatively low cost of wireless data in Japan, and the ubiquity of the cellphone are probably factors. But the presence of keitai culture—a set of cultural practices surrounding the mobile phone—suggests that the mobile novel springs not from a print culture, but from somewhere else. Indeed, keitai novels are written (often on the phones themselves) in a manner that lends itself to the constraints of highly portable devices with small screens, and provides new modes of engagement and communication. Their editors attribute the success of keitai novels to how well they fit into the lifestyle of their target demographic, and how they act as community nodes around which readers and writers interact (Hani). Although some will instinctively suggest that long-form narratives are doomed with such an approach, it is worthwhile remembering that, a decade ago, few considered reading long articles using a web browser and the appropriate response to computer-based media was to rewrite material to suit the screen (Nielsen). However, without really noticing the change, the Web became mainstream and users began reading everything on their computers, including much longer pieces of text. Apart from the examples cited, the wider book trade has largely approached e-books by trying to replicate print culture, albeit with an electronic reading device. Until there is a significant cost and convenience benefit for readers, this approach is unlikely to be widely successful. As indicated above, those segments of the market where e-books have succeeded are those whose social practices are driven by different cultural motivations. It may well be that the full-frontal approach attempted to date is doomed to failure, and e-books would achieve more widespread adoption if the book trade took a different approach. The Amazon Kindle has not yet persuaded bookloving readers to abandon print for screen in sufficient numbers to mark a seachange. Indeed, it is unlikely that any device positioned specifically as a book replacement will succeed. Instead of seeking to make an e-book culture a replacement for print culture, effectively placing the reading of books in a silo separated from other day-to-day activities, it might be better to situate e-books within a mobility culture, as part of the burgeoning range of social activities revolving around a connected, convergent mobile device. Reading should be understood as an activity that doesn’t begin with a particular device, but is done with whatever device is at hand. In much the same way that other media producers make content available for a number of platforms, book publishers should explore the potential of the new mobile devices. Over 45 million smartphones were sold globally in the first three months of 2008 (“Gartner”)—somewhat more than the estimated shipments of e-book reading devices. As well as allowing a range of communications possibilities, these convergent devices are emerging as key elements in the new digital mediascape—one that allows users access to a broad range of media products via a single pocket-sized device. Each of those smartphones makes a perfectly adequate e-book reading device, and it might be useful to pursue a strategy that embeds book reading as one of the key possibilities of this growing mobility culture. The casual gaming market serves as an interesting example. While hardcore gamers cling to their games PCs and consoles, a burgeoning alternative games market has emerged, with a different demographic purchasing less technically challenging games for more informal gaming encounters. This market has slowly shifted to convergent mobile devices, exemplified by Sega’s success in selling 300,000 copies of Super Monkey Ball within 20 days of its release for Apple’s iphone (“Super”). Casual gamers do not necessarily go on to become hardcore games, but they are gamers nonetheless—and today’s casual games (like the aforementioned Super Monkey Ball) are yesterday’s hardcore games of choice. It might be the same for reading. The availability of e-books on mobile platforms may not result in more people embracing longer-form literature. But it will increase the number of people actually reading, and, just as casual gaming has attracted a female demographic (Wallace 8), the instant availability of appropriate reading material might sway some of those men who appear to be reluctant readers (McEwan). Rather than focus on printed books, and book-like reading devices, the industry should re-position e-books as an easily accessible content choice in a digitally converged media environment. This is more a cultural shift than a technological one—for publishers and readers alike. Situating e-books in such a way may alienate a segment of the bookloving community, but such readers are unlikely to respond to anything other than print on paper. Indeed, it may encourage a whole new demographic—unafraid of the flickering screen—to engage with the manifold attractions of “books.” References Arends, Brett. “Can Amazon’s Kindle Save You Money?” The Wall St Journal 24 June 2008. 25 June 2008 ‹http://online.wsj.com/article/SB121431458215899767.html? mod=rss_whats_news_technology>.

From elephants to ABBA fans, silicon to hormone, the following discussion uses a new research method to look at printed text, motion pictures and a teenage rebel icon. If by ‘print’ we mean a mechanically reproduced impression of a cultural symbol in a medium, then printing has been with us since before microdot security prints were painted onto cars, before voice prints, laser prints, network servers, record pressings, motion picture prints, photo prints, colour woodblock prints, before books, textile prints, and footprints. If we accept that higher mammals such as elephants have a learnt culture, then it is possible to extend a definition of printing beyond Homo sapiens. Poole reports that elephants mechanically trumpet reproductions of human car horns into the air surrounding their society. If nothing else, this cross-species, cross-cultural reproduction, this ‘ability to mimic’ is ‘another sign of their intelligence’. Observation of child development suggests that the first significant meaningful ‘impression’ made on the human mind is that of the face of the child’s nurturer – usually its mother. The baby’s mind forms an ‘impression’, a mental print, a reproducible memory data set, of the nurturer’s face, voice, smell, touch, etc. That face is itself a cultural construct: hair style, makeup, piercings, tattoos, ornaments, nutrition-influenced skin and smell, perfume, temperature and voice. A mentally reproducible pattern of a unique face is formed in the mind, and we use that pattern to distinguish ‘familiar and strange’ in our expanding social orbit. The social relations of patterned memory – of imprinting – determine the extent to which we explore our world (armed with research aids such as text print) or whether we turn to violence or self-harm (Bretherton). While our cultural artifacts (such as vellum maps or networked voice message servers) bravely extend our significant patterns into the social world and the traversed environment, it is useful to remember that such artifacts, including print, are themselves understood by our original pattern-reproduction and impression system – the human mind, developed in childhood. The ‘print’ is brought to mind differently in different discourses. For a reader, a ‘print’ is a book, a memo or a broadsheet, whether it is the Indian Buddhist Sanskrit texts ordered to be printed in 593 AD by the Chinese emperor Sui Wen-ti (Silk Road) or the US Defense Department memo authorizing lower ranks to torture the prisoners taken by the Bush administration (Sanchez, cited in ABC). Other fields see prints differently. For a musician, a ‘print’ may be the sheet music which spread classical and popular music around the world; it may be a ‘record’ (as in a ‘recording’ session), where sound is impressed to wax, vinyl, charged silicon particles, or the alloys (Smith, “Elpida”) of an mp3 file. For the fine artist, a ‘print’ may be any mechanically reproduced two-dimensional (or embossed) impression of a significant image in media from paper to metal, textile to ceramics. ‘Print’ embraces the Japanese Ukiyo-e colour prints of Utamaro, the company logos that wink from credit card holographs, the early photographs of Talbot, and the textured patterns printed into neolithic ceramics. Computer hardware engineers print computational circuits. Homicide detectives investigate both sweaty finger prints and the repeated, mechanical gaits of suspects, which are imprinted into the earthy medium of a crime scene. For film makers, the ‘print’ may refer to a photochemical polyester reproduction of a motion picture artifact (the reel of ‘celluloid’), or a DVD laser disc impression of the same film. Textualist discourse has borrowed the word ‘print’ to mean ‘text’, so ‘print’ may also refer to the text elements within the vision track of a motion picture: the film’s opening titles, or texts photographed inside the motion picture story such as the sword-cut ‘Z’ in Zorro (Niblo). Before the invention of writing, the main mechanically reproduced impression of a cultural symbol in a medium was the humble footprint in the sand. The footprints of tribes – and neighbouring animals – cut tracks in the vegetation and the soil. Printed tracks led towards food, water, shelter, enemies and friends. Having learnt to pattern certain faces into their mental world, children grew older and were educated in the footprints of family and clan, enemies and food. The continuous impression of significant foot traffic in the medium of the earth produced the lines between significant nodes of prewriting and pre-wheeled cultures. These tracks were married to audio tracks, such as the song lines of the Australian Aborigines, or the ballads of tramping culture everywhere. A typical tramping song has the line, ‘There’s a track winding back to an old-fashion shack along the road to Gundagai,’ (O’Hagan), although this colonial-style song was actually written for radio and became an international hit on the airwaves, rather than the tramping trails. The printed tracks impressed by these cultural flows are highly contested and diverse, and their foot prints are woven into our very language. The names for printed tracks have entered our shared memory from the intersection of many cultures: ‘Track’ is a Germanic word entering English usage comparatively late (1470) and now used mainly in audio visual cultural reproduction, as in ‘soundtrack’. ‘Trek’ is a Dutch word for ‘track’ now used mainly by ecotourists and science fiction fans. ‘Learn’ is a Proto-Indo-European word: the verb ‘learn’ originally meant ‘to find a track’ back in the days when ‘learn’ had a noun form which meant ‘the sole of the foot’. ‘Tract’ and ‘trace’ are Latin words entering English print usage before 1374 and now used mainly in religious, and electronic surveillance, cultural reproduction. ‘Trench’ in 1386 was a French path cut through a forest. ‘Sagacity’ in English print in 1548 was originally the ability to track or hunt, in Proto-Indo-European cultures. ‘Career’ (in English before 1534) was the print made by chariots in ancient Rome. ‘Sleuth’ (1200) was a Norse noun for a track. ‘Investigation’ (1436) was Latin for studying a footprint (Harper). The arrival of symbolic writing scratched on caves, hearth stones, and trees (the original meaning of ‘book’ is tree), brought extremely limited text education close to home. Then, with baked clay tablets, incised boards, slate, bamboo, tortoise shell, cast metal, bark cloth, textiles, vellum, and – later – paper, a portability came to text that allowed any culture to venture away from known ‘foot’ paths with a reduction in the risk of becoming lost and perishing. So began the world of maps, memos, bills of sale, philosophic treatises and epic mythologies. Some of this was printed, such as the mechanical reproduction of coins, but the fine handwriting required of long, extended, portable texts could not be printed until the invention of paper in China about 2000 years ago. Compared to lithic architecture and genes, portable text is a fragile medium, and little survives from the millennia of its innovators. The printing of large non-text designs onto bark-paper and textiles began in neolithic times, but Sui Wen-ti’s imperial memo of 593 AD gives us the earliest written date for printed books, although we can assume they had been published for many years previously. The printed book was a combination of Indian philosophic thought, wood carving, ink chemistry and Chinese paper. The earliest surviving fragment of paper-print technology is ‘Mantras of the Dharani Sutra’, a Buddhist scripture written in the Sanskrit language of the Indian subcontinent, unearthed at an early Tang Dynasty site in Xian, China – making the fragment a veteran piece of printing, in the sense that Sanskrit books had been in print for at least a century by the early Tang Dynasty (Chinese Graphic Arts Net). At first, paper books were printed with page-size carved wooden boards. Five hundred years later, Pi Sheng (c.1041) baked individual reusable ceramic characters in a fire and invented the durable moveable type of modern printing (Silk Road 2000). Abandoning carved wooden tablets, the ‘digitizing’ of Chinese moveable type sped up the production of printed texts. In turn, Pi Sheng’s flexible, rapid, sustainable printing process expanded the political-cultural impact of the literati in Asian society. Digitized block text on paper produced a bureaucratic, literate elite so powerful in Asia that Louis XVI of France copied China’s print-based Confucian system of political authority for his own empire, and so began the rise of the examined public university systems, and the civil service systems, of most European states (Watson, Visions). By reason of its durability, its rapid mechanical reproduction, its culturally agreed signs, literate readership, revered authorship, shared ideology, and distributed portability, a ‘print’ can be a powerful cultural network which builds and expands empires. But print also attacks and destroys empires. A case in point is the Spanish conquest of Aztec America: The Aztecs had immense libraries of American literature on bark-cloth scrolls, a technology which predated paper. These libraries were wiped out by the invading Spanish, who carried a different book before them (Ewins). In the industrial age, the printing press and the gun were seen as the weapons of rebellions everywhere. In 1776, American rebels staffed their ‘Homeland Security’ units with paper makers, knowing that defeating the English would be based on printed and written documents (Hahn). Mao Zedong was a book librarian; Mao said political power came out of the barrel of a gun, but Mao himself came out of a library. With the spread of wireless networked servers, political ferment comes out of the barrel of the cell phone and the internet chat room these days. Witness the cell phone displays of a plane hitting a tower that appear immediately after 9/11 in the Middle East, or witness the show trials of a few US and UK lower ranks who published prints of their torturing activities onto the internet: only lower ranks who published prints were arrested or tried. The control of secure servers and satellites is the new press. These days, we live in a global library of burning books – ‘burning’ in the sense that ‘print’ is now a charged silicon medium (Smith, “Intel”) which is usually made readable by connecting the chip to nuclear reactors and petrochemically-fired power stations. World resources burn as we read our screens. Men, women, children burn too, as we watch our infotainment news in comfort while ‘their’ flickering dead faces are printed in our broadcast hearths. The print we watch is not the living; it is the voodoo of the living in the blackout behind the camera, engaging the blood sacrifice of the tormented and the unfortunate. Internet texts are also ‘on fire’ in the third sense of their fragility and instability as a medium: data bases regularly ‘print’ fail-safe copies in an attempt to postpone the inevitable mechanical, chemical and electrical failure that awaits all electronic media in time. Print defines a moral position for everyone. In reporting conflict, in deciding to go to press or censor, any ‘print’ cannot avoid an ethical context, starting with the fact that there is a difference in power between print maker, armed perpetrators, the weak, the peaceful, the publisher, and the viewer. So many human factors attend a text, video or voice ‘print’: its very existence as an aesthetic object, even before publication and reception, speaks of unbalanced, and therefore dynamic, power relationships. For example, Graham Greene departed unscathed from all the highly dangerous battlefields he entered as a novelist: Riot-torn Germany, London Blitz, Belgian Congo, Voodoo Haiti, Vietnam, Panama, Reagan’s Washington, and mafia Europe. His texts are peopled with the injustices of the less fortunate of the twentieth century, while he himself was a member of the fortunate (if not happy) elite, as is anyone today who has the luxury of time to read Greene’s works for pleasure. Ethically a member of London and Paris’ colonizers, Greene’s best writing still electrifies, perhaps partly because he was in the same line of fire as the victims he shared bread with. In fact, Greene hoped daily that he would escape from the dreadful conflicts he fictionalized via a body bag or an urn of ashes (see Sherry). In reading an author’s biography we have one window on the ethical dimensions of authority and print. If a print’s aesthetics are sometimes enduring, its ethical relationships are always mutable. Take the stylized logo of a running athlete: four limbs bent in a rotation of action. This dynamic icon has symbolized ‘good health’ in Hindu and Buddhist culture, from Madras to Tokyo, for thousands of years. The cross of bent limbs was borrowed for the militarized health programs of 1930s Germany, and, because of what was only a brief, recent, isolated yet monstrously horrific segment of its history in print, the bent-limbed swastika is now a vilified symbol in the West. The sign remains ‘impressed’ differently on traditional Eastern culture, and without the taint of Nazism. Dramatic prints are emotionally charged because, in depicting Homo sapiens in danger, or passionately in love, they elicit a hormonal reaction from the reader, the viewer, or the audience. The type of emotions triggered by a print vary across the whole gamut of human chemistry. A recent study of three genres of motion picture prints shows a marked differences in the hormonal responses of men compared to women when viewing a romance, an actioner, and a documentary (see Schultheiss, Wirth, and Stanton). Society is biochemically diverse in its engagement with printed culture, which raises questions about equality in the arts. Motion picture prints probably comprise around one third of internet traffic, in the form of stolen digitized movie files pirated across the globe via peer-to-peer file transfer networks (p2p), and burnt as DVD laser prints (BBC). There is also a US 40 billion dollar per annum legitimate commerce in DVD laser pressings (Grassl), which would suggest an US 80 billion per annum world total in legitimate laser disc print culture. The actively screen literate, or the ‘sliterati’ as I prefer to call them, research this world of motion picture prints via their peers, their internet information channels, their television programming, and their web forums. Most of this activity occurs outside the ambit of universities and schools. One large site of sliterate (screen literate) practice outside most schooling and official research is the net of online forums at imdb.com (International Movie Data Base). Imdb.com ‘prints’ about 25,000,000 top pages per month to client browsers. Hundreds of sliterati forums are located at imdb, including a forum for the Australian movie, Muriel’s Wedding (Hogan). Ten years after the release of Muriel’s Wedding, young people who are concerned with victimization and bullying still log on to http://us.imdb.com/title/tt0110598/board/> and put their thoughts into print: I still feel so bad for Muriel in the beginning of the movie, when the girls ‘dump’ her, and how much the poor girl cried and cried! Those girls were such biartches…I love how they got their comeuppance! bunniesormaybemidgets’s comment is typical of the current discussion. Muriel’s Wedding was a very popular film in its first cinema edition in Australia and elsewhere. About 30% of the entire over-14 Australian population went to see this photochemical polyester print in the cinemas on its first release. A decade on, the distributors printed a DVD laser disc edition. The story concerns Muriel (played by Toni Collette), the unemployed daughter of a corrupt, ‘police state’ politician. Muriel is bullied by her peers and she withdraws into a fantasy world, deluding herself that a white wedding will rescue her from the torments of her blighted life. Through theft and deceit (the modus operandi of her father) Muriel escapes to the entertainment industry and finds a ‘wicked’ girlfriend mentor. From a rebellious position of stubborn independence, Muriel plays out her fantasy. She gets her white wedding, before seeing both her father and her new married life as hollow shams which have goaded her abandoned mother to suicide. Redefining her life as a ‘game’ and assuming responsibility for her independence, Muriel turns her back on the mainstream, image-conscious, female gang of her oppressed youth. Muriel leaves the story, having rekindled her friendship with her rebel mentor. My methodological approach to viewing the laser disc print was to first make a more accessible, coded record of the entire movie. I was able to code and record the print in real time, using a new metalanguage (Watson, “Eyes”). The advantage of Coding is that ‘thinks’ the same way as film making, it does not sidetrack the analyst into prose. The Code splits the movie print into Vision Action [vision graphic elements, including text] (sound) The Coding splits the vision track into normal action and graphic elements, such as text, so this Coding is an ideal method for extracting all the text elements of a film in real time. After playing the film once, I had four and a half tightly packed pages of the coded story, including all its text elements in square brackets. Being a unique, indexed hard copy, the Coded copy allowed me immediate access to any point of the Muriel’s Wedding saga without having to search the DVD laser print. How are ‘print’ elements used in Muriel’s Wedding? Firstly, a rose-coloured monoprint of Muriel Heslop’s smiling face stares enigmatically from the plastic surface of the DVD picture disc. The print is a still photo captured from her smile as she walked down the aisle of her white wedding. In this print, Toni Collette is the Mona Lisa of Australian culture, except that fans of Muriel’s Wedding know the meaning of that smile is a magical combination of the actor’s art: the smile is both the flush of dreams come true and the frightening self deception that will kill her mother. Inserting and playing the disc, the text-dominant menu appears, and the film commences with the text-dominant opening titles. Text and titles confer a legitimacy on a work, whether it is a trade mark of the laser print owners, or the household names of stars. Text titles confer status relationships on both the presenters of the cultural artifact and the viewer who has entered into a legal license agreement with the owners of the movie. A title makes us comfortable, because the mind always seeks to name the unfamiliar, and a set of text titles does that job for us so that we can navigate the ‘tracks’ and settle into our engagement with the unfamiliar. The apparent ‘truth’ and ‘stability’ of printed text calms our fears and beguiles our uncertainties. Muriel attends the white wedding of a school bully bride, wearing a leopard print dress she has stolen. Muriel’s spotted wild animal print contrasts with the pure white handmade dress of the bride. In Muriel’s leopard textile print, we have the wild, rebellious, impoverished, inappropriate intrusion into the social ritual and fantasy of her high-status tormentor. An off-duty store detective recognizes the printed dress and calls the police. The police are themselves distinguished by their blue-and-white checked prints and other mechanically reproduced impressions of cultural symbols: in steel, brass, embroidery, leather and plastics. Muriel is driven in the police car past the stenciled town sign (‘Welcome To Porpoise Spit’ heads a paragraph of small print). She is delivered to her father, a politician who presides over the policing of his town. In a state where the judiciary, police and executive are hijacked by the same tyrant, Muriel’s father, Bill, pays off the police constables with a carton of legal drugs (beer) and Muriel must face her father’s wrath, which he proceeds to transfer to his detested wife. Like his daughter, the father also wears a spotted brown print costume, but his is a batik print from neighbouring Indonesia (incidentally, in a nation that takes the political status of its batik prints very seriously). Bill demands that Muriel find the receipt for the leopard print dress she claims she has purchased. The legitimate ownership of the object is enmeshed with a printed receipt, the printed evidence of trade. The law (and the paramilitary power behind the law) are legitimized, or contested, by the presence or absence of printed text. Muriel hides in her bedroom, surround by poster prints of the pop group ABBA. Torn-out prints of other people’s weddings adorn her mirror. Her face is embossed with the clown-like primary colours of the marionette as she lifts a bouquet to her chin and stares into the real time ‘print’ of her mirror image. Bill takes the opportunity of a business meeting with Japanese investors to feed his entire family at ‘Charlie Chan’’s restaurant. Muriel’s middle sister sloppily wears her father’s state election tee shirt, printed with the text: ‘Vote 1, Bill Heslop. You can’t stop progress.’ The text sets up two ironic gags that are paid off on the dialogue track: “He lost,’ we are told. ‘Progress’ turns out to be funding the concreting of a beach. Bill berates his daughter Muriel: she has no chance of becoming a printer’s apprentice and she has failed a typing course. Her dysfunction in printed text has been covered up by Bill: he has bribed the typing teacher to issue a printed diploma to his daughter. In the gambling saloon of the club, under the arrays of mechanically repeated cultural symbols lit above the poker machines (‘A’ for ace, ‘Q’ for queen, etc.), Bill’s secret girlfriend Diedre risks giving Muriel a cosmetics job. Another text icon in lights announces the surf nightclub ‘Breakers’. Tania, the newly married queen bitch who has made Muriel’s teenage years a living hell, breaks up with her husband, deciding to cash in his negotiable text documents – his Bali honeymoon tickets – and go on an island holiday with her girlfriends instead. Text documents are the enduring site of agreements between people and also the site of mutations to those agreements. Tania dumps Muriel, who sobs and sobs. Sobs are a mechanical, percussive reproduction impressed on the sound track. Returning home, we discover that Muriel’s older brother has failed a printed test and been rejected for police recruitment. There is a high incidence of print illiteracy in the Heslop family. Mrs Heslop (Jeannie Drynan), for instance, regularly has trouble at the post office. Muriel sees a chance to escape the oppression of her family by tricking her mother into giving her a blank cheque. Here is the confluence of the legitimacy of a bank’s printed negotiable document with the risk and freedom of a blank space for rebel Muriel’s handwriting. Unable to type, her handwriting has the power to steal every cent of her father’s savings. She leaves home and spends the family’s savings at an island resort. On the island, the text print-challenged Muriel dances to a recording (sound print) of ABBA, her hand gestures emphasizing her bewigged face, which is made up in an impression of her pop idol. Her imitation of her goddesses – the ABBA women, her only hope in a real world of people who hate or avoid her – is accompanied by her goddesses’ voices singing: ‘the mystery book on the shelf is always repeating itself.’ Before jpeg and gif image downloads, we had postcard prints and snail mail. Muriel sends a postcard to her family, lying about her ‘success’ in the cosmetics business. The printed missal is clutched by her father Bill (Bill Hunter), who proclaims about his daughter, ‘you can’t type but you really impress me’. Meanwhile, on Hibiscus Island, Muriel lies under a moonlit palm tree with her newly found mentor, ‘bad girl’ Ronda (Rachel Griffiths). In this critical scene, where foolish Muriel opens her heart’s yearnings to a confidante she can finally trust, the director and DP have chosen to shoot a flat, high contrast blue filtered image. The visual result is very much like the semiabstract Japanese Ukiyo-e woodblock prints by Utamaro. This Japanese printing style informed the rise of European modern painting (Monet, Van Gogh, Picasso, etc., were all important collectors and students of Ukiyo-e prints). The above print and text elements in Muriel’s Wedding take us 27 minutes into her story, as recorded on a single page of real-time handwritten Coding. Although not discussed here, the Coding recorded the complete film – a total of 106 minutes of text elements and main graphic elements – as four pages of Code. Referring to this Coding some weeks after it was made, I looked up the final code on page four: taxi [food of the sea] bq. Translation: a shop sign whizzes past in the film’s background, as Muriel and Ronda leave Porpoise Spit in a taxi. Over their heads the text ‘Food Of The Sea’ flashes. We are reminded that Muriel and Ronda are mermaids, fantastic creatures sprung from the brow of author PJ Hogan, and illuminated even today in the pantheon of women’s coming-of-age art works. That the movie is relevant ten years on is evidenced by the current usage of the Muriel’s Wedding online forum, an intersection of wider discussions by sliterate women on imdb.com who, like Muriel, are observers (and in some cases victims) of horrific pressure from ambitious female gangs and bullies. Text is always a minor element in a motion picture (unless it is a subtitled foreign film) and text usually whizzes by subliminally while viewing a film. By Coding the work for [text], all the text nuances made by the film makers come to light. While I have viewed Muriel’s Wedding on many occasions, it has only been in Coding it specifically for text that I have noticed that Muriel is a representative of that vast class of talented youth who are discriminated against by print (as in text) educators who cannot offer her a life-affirming identity in the English classroom. Severely depressed at school, and failing to type or get a printer’s apprenticeship, Muriel finds paid work (and hence, freedom, life, identity, independence) working in her audio visual printed medium of choice: a video store in a new city. Muriel found a sliterate admirer at the video store but she later dumped him for her fantasy man, before leaving him too. One of the points of conjecture on the imdb Muriel’s Wedding site is, did Muriel (in the unwritten future) get back together with admirer Brice Nobes? That we will never know. While a print forms a track that tells us where culture has been, a print cannot be the future, a print is never animate reality. At the end of any trail of prints, one must lift one’s head from the last impression, and negotiate satisfaction in the happening world.

Nuclear domain can be considered as a challenging field of application for control systems and the related electronic technology. A prototypal version for controllers is often mandatory for a preventive test and performance evaluation. Control engineers often develop very accurate model of a specific process with very sophisticated control laws using a simulation environment. Even if simulations are fundamental for studying the process and selecting the best control technique, this theoretical effort can be a critical issue for the subsequent hardware implementation of the controller on real electronic devices, leading to a difficult conversion from software to hardware. In this context, the so called Hardware-In-the-Loop HIL simulations is a valid help, allowing a plant process to be simulated in a real time environment and the control unit to be realized on a real component and included in the whole simulation. In this work, HIL simulations are presented and compared to fully software simulations in case of the prototype realization of a pressure controller for a Pressurized Water Reactor PWR. Digital hardware technology is here introduced from the scratch into the project, and the physical implementation of the control unit is taken into account from the beginning, with a significant improvement of the accuracy of the controller in the real process. The control unit is based on a Field-Progammable-Gate-Array (FPGA), a widespread device for real-time control. FPGAs let designers to program a wide number of digital gates in their functionalities with a intrinsic determinism. In addition, processes can be managed in a real parallelism and without the resource sharing as in a CPU operating system. Results demonstrate the effectiveness of such an approach.
