History of Data Centre Development
2012
International audience; Computers are used to solve different problems. For solving these problems computer software and hardware are used, but for operations of those computing facilities a Data Centre is necessary. Therefore, development of the data centre is subordinated to solvable tasks and computing resources. We are studying the history of data centres’ development, taking into consideration an understanding of this. In the beginning of the computer era computers were installed in computing centres, because all computing centres have defined requirements according to whom their operation is intended for. Even though the concept of ‘data centre’ itself has been used since the 1990s, t…
Quine’s Fluted Fragment is Non-elementary
2016
We study the fluted fragment, a decidable fragment of first-order logic with an unbounded number of variables, originally identified by W.V. Quine. We show that the satisfiability problem for this fragment has non-elementary complexity, thus refuting an earlier published claim by W.C. Purdy that it is in NExpTime. More precisely, we consider, for all m greater than 1, the intersectionof the fluted fragment and the m-variable fragment of first-order logic. We show that this subfragment forces (m/2)-tuply exponentially large models, and that its satisfiability problem is (m/2)-NExpTime-hard. We round off by using a corrected version of Purdy’s construction to show that the m-variable fluted f…
Relational work in multimodal networked interactions on Facebook
2018
Abstract The paper argues that the notion of Relational Work (Locher and Watts 2005) needs to be expanded to be able to account for sociability in the networked interactions afforded by social platforms such as Facebook. Thus, the aim of this paper is to explore how the nature of networked interactions impacts the emergence of relational practices therein. Importantly, Relational Work is a language based framework whereas networked interactions are highly multimodal. By applying Norris’ (2004) multimodal framework to the analysis of a Facebook wall event, we show how key sociability functions are carried out by semiotic modes other than language. Furthermore, the analysis shows how relation…
Material scaffolding : Supporting the comprehension of migrant cleaners at work
2016
Linguistic diversity is growing in labour markets throughout Europe, including Finland, where cleaning is the most common job for immigrants. This paper explores material scaffolding provided for second language users in tasks involved in cleaning work. The notion of ‘scaffolding’ refers to temporary and adaptive support, and here the emphasis is especially on ‘material scaffolding’, that is, material artefacts and body movements employed in mentoring. The theoretical framework of the study is van Lier’s (2004) ecological perspective on language learning, and a discourse-ethnographic perspective of nexus analysis (Scollon and Scollon 2004) is adopted to analyse the ethnographic data collect…
Deriving Enhanced Universal Dependencies from a Hybrid Dependency-Constituency Treebank
2018
The treebanks provided by the Universal Dependencies (UD) initiative are a state-of-the-art resource for cross-lingual and monolingual syntax-based linguistic studies, as well as for multilingual dependency parsing. Creating a UD treebank for a language helps further the UD initiative by providing an important dataset for research and natural language processing in that language. In this paper, we describe how we created a UD treebank for Latvian, and how we obtained both the basic and enhanced UD representations from the data in Latvian Treebank which is annotated according to a hybrid dependency-constituency grammar model. The hybrid model was inspired by Lucien Tesniere’s dependency gram…
Business Process Management in Financial and Non-Financial Institutions: Payment Process Modelling in Financial Flows Management
2017
Business process management is a progressively developing area of science, which is seen as the most modern and forward-looking innovative. Modern business operations remain highly dependent on IT solutions to steer the processes. Business process management solutions have been the clue for easing daily business operations. IT solutions have actively penetrated the working environment in all areas of business, especially the financial sector. It is beyond to imagine modern financial markets and institutions without IT software support. Not only billing, calculation and payment processes, even stock pricing, market analysis and risk monitor tools are fully computerized through business proce…
MOF-VM: Instantiation Revisited
2016
The Model-Driven Architecture (MDA) is based on an understanding of a hierarchy of levels that are placed on top of each other and that are connected with instantiation. For practical MDA use, it is important to be clear about the kinds of objects that reside on the different levels and the relations between them as well as relations to objects outside of the MDA domain. This article aims at enhancing the understanding of these objects and relations by relating them to a virtual MOF machine.
Sharing cultural knowledge at work: a study of chat interactions of an internationally dispersed team
2015
Tässä artikkelissa tarkastellaan etnometodologisen jäsenkategorisoinnin analyysin avulla, kuinka kansainvälisesti hajautetun tiimin jäsenet jakavat kulttuurista tietoa Skype™ -keskusteluissaan. Tarkemmin katsotaan sitä, miten osallistujat luokittelevat itsensä ja muut tiimin jäsenet ’kulttuurisiksi tietäjiksi’ ja ’ei tietäjiksi’. Analyysissa havaittiin neljä tapaa, joilla tiimin jäsenet jakoivat tietoa samalla kun he hallinnoivat tehtävien jakelua ja suorittamista sekä rakensivat yhteisymmärrystä vuorovaikutuksessa. Tutkimuksen tulokset osoittavat, että kulttuurinen tieto on dynaamisesti muuttuvaa, kontekstisidonnaista ja vuorovaikutuksessa rakentuvaa. Sen sijaan että kulttuurisuus haittais…
Training the modern translator – the acquisition of digital competencies through blended learning
2019
This paper presents the ERASMUS+ DigiLing project, which aims to teach and improve linguists’ and translators’ skills and knowledge of digitalisation to prepare them for today’s job market. Against this background, it discusses the development of digital competencies and distinguishes them from traditional domain-specific and general competencies. For the purpose of competence acquisition, six online courses have been created which all revolve around the field of ‘digital linguistics’, including localization in the digital age and post-editing machine translation. We provide an overview of the project, the course contents and the didactic methodology. In addition, we discuss which competenc…
Affordances and constraints: Second language learning in cleaning work
2016
This paper examines opportunities for language learning in a cleaning job, which is a typical entry-level job for immigrants. An ethnographic case study approach is taken to investigate examples of the conditions that allow or prevent language learning for the focal participant, a sub-Saharan man who works as a cleaner in Finland. This case illustrates on a micro-scale the impact of the new economy on a worker in a company that has outsourced its cleaning services. Theoretically and methodologically, the study applies van Lier’s (2004) ecological approach to language learning and Scollon and Scollon’s (2004) nexus analysis. The analysis of interaction order shows that within outsourced clea…
