« Le roman est agréablement traduit » : Étude comparative sur la visibilité des traductions et des traducteurs en Finlande et en France à travers des critiques des livres

Pro gradu -työssä tutkitaan ja vertaillaan käännöskirjallisuuden arvosteluja Ranskassa ja Suomessa. Empiirinen aineisto koostuu kaikista Helsingin Sanomien ja Le Monden vuonna 2003 julkaisemista arvosteluista. Lehdissä oli yhteensä 2691 arvosteltua kirjaa, joista 845 oli käännöksiä. Päätavoite on ollut selvittää näiden valtasanomalehtien kritiikkejä tutkimalla, kummassa maassa kääntäjän ja käännöksen asema on näkyvämpi ja minkälaisia julkaistut käännöskritiikit ovat. Lisäksi tavoitteena on ollut tutkia, kumpi lehdistä on avoimempi vieraskielisiä kirjoja ja käännöksiä kohtaan. Kirja-arvostelujen lähemmälle tutkimiselle luodaan pohjaa perehtymällä kääntäjän ja käännöksen näkyvyyteen liittyviin seikkoihin. Tässä käytetään hyväksi Koskisen (2000) tutkimusta. Tutkimuksessa tarkastellaan myös, millainen on hyvä käännös eri kääntäjien ja tutkijoiden mielestä, sekä muita saman aihepiirin tutkimuksia ja aiheesta vallalla ollutta keskustelua. Lisäksi selvitetään, miksi laadukkaat käännösarvostelut ovat harvinaisia ja mistä tämä johtuu. Analyysivaiheen kvantitatiivisessa osassa perehdytään käännösten määrälliseen osuuteen sekä aineistossa että Ranskan ja Suomen kokonaisjulkaisumäärissä. Aineiston käännösarvostelut luokitellaan niiden sisällön mukaan. Tässä on käytetty soveltuvin osin Gullinin (1998) kehittelemää mallia. Käännösarvostelujen sisältöanalyysissa kiinnitetään huomiota niiden käännöstä ja kääntäjää koskeviin kommentteihin. Arvostelujen laadun ja kriitikkojen käyttämien arvosteluperusteiden pohdinta nojautuu aiheesta aikaisemmin tehtyihin teoreettisiin sekä empiirisiin tutkimuksiin. Pro gradu -työ sisältää myös erillisen katsauksen käännettyjen lastenkirjojen arvosteluihin sekä arvostelujen ulkopuolisiin kääntäjiin ja kääntämiseen liittyviin artikkeleihin. Koko tutkimuksen ajan lähestymistapa on vertaileva Le Monden ja Helsingin Sanomien välillä. Tutkimuksesta selviää, että Le Monde julkaisee huomattavasti enemmän kirja-arvosteluja. Molemmat lehdet sisältävät kuitenkin suhteellisesti yhtä paljon arvosteluja käännöskirjoista. Helsingin Sanomissa on enemmän vieraskielisten teosten arvosteluja, ja käännösten ja kääntäjän asema on huomattavasti näkyvämpi lehden kritiikeissä. Suurin osa Le Monden käännösarvosteluista sisältää vain kääntäjän nimen bibliografisissa tiedoissa. Helsingin Sanomissa vain alle puolet käännöskirjoista on arvosteltu tällä tavoin. Myös kritiikit, joissa kääntäjän nimeä ei mainita ollenkaan, ovat yleisempiä ranskalaislehdessä. Suhteellisen pieni osa käännösarvosteluista arvioi käännöksen laatua. Näille arvioille on ominaista perustelujen ja analyysin puuttuminen ja ne ovat usein lyhyitä. Arviot ovat sävyltään enimmäkseen positiivisia tai neutraaleja. Hyvin yleistä on myös se, että kriitikko sekoittaa kaksi eri asiaa: kääntäjän ja kirjailijan tyylin. Yleisin kriitikkojen käyttämä arviointikriteeri on tutkia käännöksen ja kohdekielen tai käännöksen ja lähtötekstin suhdetta. Monesti arviointikriteeri jää täysin epäselväksi. Helsingin Sanomien kritiikeissä kääntäjiin viitataan huomattavasti useammin myös itse arvostelutekstissä. Lehti tuo näkyvästi esille kääntäjiä muissakin kuin kirja-arvosteluartikkeleissaan. Sen sijaan Le Mondessa ei ole pelkästään kääntäjiä käsitteleviä tekstejä.

Pre-maps : An Educational Programme for Reading Tactile Maps

It is demanding for children with visual impairment to become aware of the world beyond their immediate experience. They need to learn to control spatial experiences as a whole and understand the relationships between objects, surfaces and themselves. Tactile maps can be an excellent source of information for depicting space and environment. By means of tactile maps children can develop their spatial understanding more efficiently than through direct travel experiences supplemented with verbal explanations. Tactile maps can help children when they are learning to understand environmental, spatial, and directional concepts. The ability to read tactile maps is not self-evident; it is a skill, which must be learned. The main research question was: can children who are visually impaired learn to read tactile maps at the preschool age if they receive structural teaching? The purpose of this study was to develop an educational program for preschool children with visual impairment, the aim of which was to teach them to read tactile maps in order to strengthen their orientation skills and to encourage them to explore the world beyond their immediate experience. The study is a multiple case study describing the development of the map program consisting of eight learning tasks. The program was developed with one preschooler who was blind, and subsequently the program was implemented with three other children. Two of the children were blind from birth, one child had lost her vision at the age of two, and one child had low vision. The program was implemented in a normal preschool. Another objective of the pre-map program was to teach the preschooler with visual impairment to understand the concept of a map. The teaching tools were simple, map-like representations called pre-maps. Before a child with visual impairment can read a comprehensive tactile map, it is important to learn to understand map symbols, and how a three-dimensional model changes to a two-dimensional tactile map. All teaching sessions were videotaped; the results are based on the analysis of the videotapes. Two of the children completed the program successfully, and learned to read a tactile map. The two other children felt happy during the sessions, but it was problematic for them to engage fully in the instruction. One of the two eventually completed the program, while the other developed predominantly emerging skills. The results of the children's performances and the positive feedback from the teachers, assistants and the parents proved that this pre-map program is appropriate teaching material for preschool children who are visually impaired. The program does not demand high-level expertise; also parents, preschool teachers, and school assistants can carry out the program.

Composition operators, Aleksandrov measures and value distribution of analytic maps in the unit disc

A composition operator is a linear operator that precomposes any given function with another function, which is held fixed and called the symbol of the composition operator. This dissertation studies such operators and questions related to their theory in the case when the functions to be composed are analytic in the unit disc of the complex plane. Thus the subject of the dissertation lies at the intersection of analytic function theory and operator theory. The work contains three research articles. The first article is concerned with the value distribution of analytic functions. In the literature there are two different conditions which characterize when a composition operator is compact on the Hardy spaces of the unit disc. One condition is in terms of the classical Nevanlinna counting function, defined inside the disc, and the other condition involves a family of certain measures called the Aleksandrov (or Clark) measures and supported on the boundary of the disc. The article explains the connection between these two approaches from a function-theoretic point of view. It is shown that the Aleksandrov measures can be interpreted as kinds of boundary limits of the Nevanlinna counting function as one approaches the boundary from within the disc. The other two articles investigate the compactness properties of the difference of two composition operators, which is beneficial for understanding the structure of the set of all composition operators. The second article considers this question on the Hardy and related spaces of the disc, and employs Aleksandrov measures as its main tool. The results obtained generalize those existing for the case of a single composition operator. However, there are some peculiarities which do not occur in the theory of a single operator. The third article studies the compactness of the difference operator on the Bloch and Lipschitz spaces, improving and extending results given in the previous literature. Moreover, in this connection one obtains a general result which characterizes the compactness and weak compactness of the difference of two weighted composition operators on certain weighted Hardy-type spaces.

X-ray scattering and diffraction enhanced imaging studies of in vitro breast tissues

This thesis is a study of the x-ray scattering properties of tissues and tumours of the breast. Clinical radiography is based on the absorption of the x-rays when passing right through the human body and gives information about the densities of the tissues. Besides being absorbed, x-rays may change their direction within the tissues due to elastic scattering or even to refraction. The phenomenon of scattering is a nuisance to radiography in general, and to mammography in particular, because it reduces the quality of the images. However, scattered x-rays bear very useful information about the structure of the tissues at the supra-molecular level. Some pathologies, like breast cancer, produce alterations to the structures of the tissues, being especially evident in collagen-rich tissues. On the other hand, the change of direction due to refraction of the x-rays on the tissue boundaries can be mapped. The diffraction enhanced imaging (DEI) technique uses a perfect crystal to convert the angular deviations of the x-rays into intensity variations, which can be recorded as images. This technique is of especial interest in the cases were the densities of the tissues are very similar (like in mammography) and the absorption images do not offer enough contrast. This thesis explores the structural differences existing in healthy and pathological collagen in breast tissue samples by the small-angle x-ray scattering (SAXS) technique and compares these differences with the morphological information found in the DEI images and the histo-pathology of the same samples. Several breast tissue samples were studied by SAXS technique in the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. Scattering patterns of the different tissues of the breast were acquired and compared with the histology of the samples. The scattering signals from adipose tissue (fat), connective tissue (collagen) and necrotic tissue were identified. Moreover, a clear distinction could be done between the scattering signals from healthy collagen and from collagen from an invasive tumour. Scattering from collagen is very characteristic. It includes several scattering peaks and scattering features that carry information about the size and the spacing of the collagen fibrils in the tissues. It was found that the collagen fibrils in invaded tumours were thinner and had a d-spacing length 0,7% longer that fibrils from healthy tumours. The scattering signals from the breast tissues were compared with the histology by building colour-coded maps across the samples. They were also imaged with the DEI technique. There was a total agreement between the scattering maps, the morphological features seen in the images and the information of the histo- pathological examination. The thesis demonstrates that the x-ray scattering signal can be used to characterize tissues and that it carries important information about the pathological state of the breast tissues, thus showing the potential of the SAXS technique as a possible diagnostic tool for breast cancer.

Semi-supervised learning of WLAN radio maps

In this thesis a manifold learning method is applied to the problem of WLAN positioning and automatic radio map creation. Due to the nature of WLAN signal strength measurements, a signal map created from raw measurements results in non-linear distance relations between measurement points. These signal strength vectors reside in a high-dimensioned coordinate system. With the help of the so called Isomap-algorithm the dimensionality of this map can be reduced, and thus more easily processed. By embedding position-labeled strategic key points, we can automatically adjust the mapping to match the surveyed environment. The environment is thus learned in a semi-supervised way; gathering training points and embedding them in a two-dimensional manifold gives us a rough mapping of the measured environment. After a calibration phase, where the labeled key points in the training data are used to associate coordinates in the manifold representation with geographical locations, we can perform positioning using the adjusted map. This can be achieved through a traditional supervised learning process, which in our case is a simple nearest neighbors matching of a sampled signal strength vector. We deployed this system in two locations in the Kumpula campus in Helsinki, Finland. Results indicate that positioning based on the learned radio map can achieve good accuracy, especially in hallways or other areas in the environment where the WLAN signal is constrained by obstacles such as walls.

Future chemistry teachers use of knowledge dimensions and high-order cognitive skills in pre-laboratory concept maps

This poster describes a pilot case study, which aim is to study how future chemistry teachers use knowledge dimensions and high-order cognitive skills (HOCS) in their pre-laboratory concept maps to support chemistry laboratory work. The research data consisted of 168 pre-laboratory concept maps that 29 students constructed as a part of their chemistry laboratory studies. Concept maps were analyzed by using a theory based content analysis through Anderson & Krathwohls' learning taxonomy (2001). This study implicates that novice concept mapper students use all knowledge dimensions and applying, analyzing and evaluating HOCS to support the pre-laboratory work.
