Tutkielman aiheena on ekfrasis Gabriele D'Annunzion romaanissa Il Piacere (1889). Lähtökohtana on selvittää, millaisissa muodoissa ekfrasis esiintyy romaanissa sekä miten ekfrasis vaikuttaa teoksen tulkintatradition esille tuomaan tematiikkaan. Pyrkimyksenä on myös selkeyttää ekfrasiksen käsitettä, jonka ongelmana ovat sanaan eri aikakausina liitetyt eri merkitykset. Tärkeimpiä lähdeteoksia ovat James A.W. Heffernanin Museum of Words (1993) ja W.J.T. Mitchellin Picture Theory (1994), Marinella Cantelmon Il Piacere dei leggitori: D'Annunzio e la comunicazione letteraria (1996) sekä John Hollanderin artikkeli "The Poetics of Ekphrasis" (1988). Tutkielman avainkäsitteenä on Heffernanin määritelmä, jonka mukaan ekfrasis on sanallinen esitys kuvallisesta esityksestä. Määritelmää sovellettaessa on otettu huomioon representaatiokäsityksen avautuminen, jolloin vastaanottaja, ympäristö etc. ovat osa esitystä. Korpuksen muodostavat tapahtumaympäristöä, taideteoksia, esineistöä ja henkilöhahmoja kuvaavat ekfrastiset katkelmat. Luokittelussa toimivat alakäsitteinä Valerie Robillardin kuvaileva, attributiivinen ja assosiatiivinen ekfrasis sekä Tamar Yacobin ekfrastinen vertaus. Analyysi osoittaa, että kuvaileva ekfrasis on yleisin, mutta vain kuvitteellisten teosten yhteydessä. Katkelmissa on näkyvissä ekfrasikselle luonteenomainen kerronnallinen impulssi. Ekfrasis osallistuu tunnetun ja uuden elementin vuoropuheluun ankkuroimalla kuvitteelliset taideteokset lukijalle tuttuun ympäristöön, jolloin myös uusi tulee toden kaltaiseksi. Attributiivinen ekfrasis takaa välittömän tunnistettavuuden. Henkilöhahmot, erityisesti keskeiset naishahmot, on määritelty ekfrastisten vertausten kautta. Ekfrasis ilmentää osaltaan naishahmojen vaihdettavuuden tematiikkaa. Kyseessä on myös toiseuden haltuunotto. Kuvallisen viittaussuhteen ansiosta ekfrasis toimii tehokeinona. Tekstuaalisena strategiana ekfrasis luo siteitä tapahtumien välille ja rytmittää teoksen vaiheita. Ekfrastiset katkelmat tarjoavat myös väylän vaihtoehtoiselle tulkinnalle haastamalla tekstin totuuskäsityksen. Kuvallinen ja sanallinen esitys tuovat tekstiin omat merkityksensä, jolloin merkityskenttä laajenee. Il Piacere on intertekstuaalinen kollaasi, jossa kokonaiskuva muodostuu eri elementtien vuorovaikutuksesta. D'Annunzion mielestä kauneus on taiteen ensisijainen tarkoitus, ja ekfrasis retorisena keinona on osa pyrkimystä tavoittaa täydellinen muoto.

One of the central issues in making efficient use of IT in the design, construction and maintenance of buildings is the sharing of the digital building data across disciplines and lifecycle stages. One technology which enables data sharing is CAD layering, which to be of real use requires the definition of standards. This paper focuses on the background, objectives and effectiveness of the International standard ISO 13567, Organisation and naming of layers for CAD. In particular the efficiency and effectiveness of the standardisation and standard implementation process are in focus, rather than the technical details. The study was conducted as a qualitative study with a number of experts who responded to a semi-structured mail questionnaire, supplemented by personal interviews. The main results were that CAD layer standards based on the ISO standard have been implemented, particularly in northern European countries, but are not very widely used. A major problem which was identified was the lack of resources for marketing and implementing the standard as national variations, once it had been formally accepted.

There has been a demand for uniform CAD standards in the construction industry ever since the large-scale introduction of computer aided design systems in the late 1980s. While some standards have been widely adopted without much formal effort, other standards have failed to gain support even though considerable resources have been allocated for the purpose. Establishing a standard concerning building information modeling has been one particularly active area of industry development and scientific interest within recent years. In this paper, four different standards are discussed as cases: the IGES and DXF/DWG standards for representing the graphics in 2D drawings, the ISO 13567 standard for the structuring of building information on layers, and the IFC standard for building product models. Based on a literature study combined with two qualitative interview studies with domain experts, a process model is proposed to describe and interpret the contrasting histories of past CAD standardisation processes.

The little bustard Tetrax tetrax is a bird of agro-pastoral landscapes rapidly disappearing from most of Western Europe due to agricultural intensification. In Italy, the species is virtually extinct from the mainland but still occurs in Sardinia, where four Special Protection Areas (SPAs) have been designated in 2007 to protect the bustard and related habitat. In this note, we document a steep decline (between 50 and 87,5%) of the species during the last decade in one of those four SPAs, Plains of Semestene, Bonorva, Macomer and Bortigali. However, during summer 2009, a group of 17 individuals was found within the SPA, confirming that the species, although at low numbers (5-15 displaying males), still breeds successfully in the area. Potential limiting factors are also discussed. We urge to undertake conservation measures based on solid scientific evidence if the local population is to be saved from probable extinction in the near future.

Analisi contrastiva delle modalità di traduzione in finnico dei Tempi verbali e delle perifrasi aspettuali dell italiano (Italian Philology) The topic of this research is a contrastive study of tenses and aspect in Italian and in Finnish. The study aims to develop a research method for analyzing translations and comparable texts (non-translation) written in a target language. Thus, the analysis is based on empirical data consisting of translations of novels from Italian to Finnish and vice versa. In addition to this, for the section devoted to solutions adopted in Finnish for translating the Italian tenses Perfetto Semplice and Perfetto Composto, 39 Finnish native speakers were asked to answer questions concerning the choice of Perfekti and Imperfekti in Finnish. The responses given by the Finnish informants were compared to the choices made by translators in the target language, and in this way it was possible both to benefit from the motivation provided by native speakers to explain the selection of a tense (Imperfekti/Perfekti) in a specific context compared with the Italian formal equivalents (Perfetto Composto/Perfetto Semplice), and to define the specific features of the Finnish verb tenses. The research aims to develop a qualitative method for the analysis of formal equivalents and translational changes ( shifts ). Although, as the choice of Italian and Finnish progressive forms is optional and related to speaker preferences, besides the qualitative analysis, I also considered it necessary to operate a quantitative one in order to find out whether the two items share the same degree of correspondence in frequency of use. In this study I explain translation choices in light of cognitive grammar, suggesting that particular translation relationships derive from so-called construal operations. I use the concepts of cognitive linguistics not only to analyze the convergences and divergences of the two aspectual systems, but also to redefine some general procedures related to the phenomenon of translation. For the practical analysis of the corpus were for the most part employed theoretical categories developed in a framework proposed by Pier Marco Bertinetto. Following this approach, the notions of aspect (the morphologic or morphosyntactic, subjective level) and actionality (the lexical aspect or objective level, traditionally Aktionsart) are carefully distinguished. This also allowed me to test the applicability of these distinctions to two languages typologically different from each other. The data allowed both the analysis of the semantic and pragmatic features that determine tense and aspect choices in these two languages, and to discover the correspondences between the two language systems and the strategies that translators are forced to resort to in particular situations. The research provides not only a detailed and analytically argued inventory about possible solutions for translating Italian tenses and aspectual devices in Finnish that could be of pedagogical relevance, but also new contributions about the specific uses of time-aspectual devices in the two languages in question.
