0-visio - teoriasta käytännöksi : Varsinais-Suomen ja Satakunnan maakuntien liikenneturvallisuussuunnitelma 2012-2016

Liikenneturvallisuus syntyy eri osapuolten toiminnan ja yhteistyön tuloksena. Poliitikot päättävät yhteiskunnan suunnittelusta ja liikennejärjestelmästä, suunnittelijat toteuttavat poliitikkojen tekemiä päätöksiä, virkamiehet laativat lakiehdotuksia ja sääntöjä, ELY-keskus ja kunnat vastaavat teistä ja niiden kunnosta, poliisi valvoo liikennesääntöjen noudattamista, Liikenneturva tiedottaa ja kouluttaa, yritykset, yhteisöt ja yksityiset ihmiset tilaavat ja käyttävät kuljetuspalveluja ja kaikki kuntalaiset osallistuvat liikenteeseen. Liikenneturvallisuussuunnitelma toimii työkaluna Varsinais-Suomen ja Satakunnan liikenneturvallisuustyössä. Alueellisen liikenneturvallisuustyön nollavisio ja tavoitteet asetettiin valtakunnallisen liikenneturvallisuussuunnitelman, alueen nykytila-analyysin sekä suunnitelman laadinnan aikana sidosryhmien kanssa käydyn keskustelun pohjalta. Nollavision mukaan kenenkään ei tarvitse kuolla tai loukkaantua vakavasti liikenteessä. Lisäksi visiona on vastuullinen liikkuminen, joka myös koetaan turvalliseksi. Seitsemän kohdan ohjelmaan nollavision toteuttamiseksi on tiivistetty tärkeimmät toimet. Yksilöityihin toimenpiteisiin on kirjattu maankäytön suunnitteluun, kestävään liikkumiseen, liikenneympäristöön ja liikennekäyttäytymiseen liittyviä toimenpiteitä. Lisäksi liikenneturvallisuusyhteistyöhön kohdistuvia toimenpiteitä sisältyy suunnitelmaan. Toimenpiteiden toteuttamisen vastuu- ja yhteistyötahoja on useita. Toimenpiteet kohdistuvat alueen tielläliikkujiin, organisaatioihin ja päätöksentekijöihin. Pitkän aikavälin ja valtakunnallisen tason toimenpiteet edesauttavat liikenneturvallisuuden kehittymistä toivottuun suuntaan. Vaikutustarkastelu osoittaa, että asetettujen tavoitteiden saavuttaminen vaatii laajaa keinovalikoimaa, usean toimijan välistä yhteistyötä sekä resursseja liikenneturvallisuustyöhön. Tämä liikenneturvallisuussuunnitelma haastaa eri hallinnonalat, viranomaiset, järjestöt ja yritykset omalta osaltaan toteuttamaan toimia, jotka vievät kohti nollavisiota. Suunnitelman toteutuminen edellyttää, että sillä on kuntien ja päättäjien tuki. Varsinais-Suomen ja Satakunnan liikenteen tulevaisuus kehittyy suunnitelman mukaisesti, jos liikenteen vastuunkantajat sitoutuvat suunnitelman vision periaatteisiin ja pitävät elämää suojelevia arvoja toimintansa perustana.

Regressiotestaus- ja ylläpitotyökalu Ohjelmoinnin perusteet -kurssin Python-harjoitustehtäville

Tässä kandidaatintyössä suunnitellaan ja toteutetaan regressiotestaus- ja ylläpitotyökalu Ohjelmoinnin perusteet -kurssin Python-ohjelmointitehtäville. Työkalun on tarkoitus auttaa kurssin vastuuhenkilöitä selvittämään kurssilla käytettyjen harjoitustehtävien esimerkkiratkaisujen toimivuus Python-versiossa, jota kurssilla aiotaan käyttää ohjelmointiympäristönä seuraavana vuonna, ja helpottaa harjoitusmateriaalin yhdenmukaisuuden varmistamista silloin kun Python-versiota vaihdetaan tai materiaaliin tehdään muutoksia. Työssä tutkitaan, miten tarkoitukseen sopiva yleispätevä testaustyökalu voidaan kehittää, mitä seikkoja sen suunnittelussa on otettava huomioon ja mitä ongelmia kehittämiseen liittyy. Yleispätevän testaustyökalun kehittäminen osoittautui hankalaksi, vaikka testattavat ohjelmat ovat yksinkertaisia. Harjoitusmateriaaliin kuuluneiden yli 50 ohjelman testaamisessa tarvittavia tiedostoja oli yhteensä hyvin suuri määrä, ja niiden käsittelemiseksi työkalussa ja sen ulkopuolella oli vaikeaa valita optimaalista hakemistorakennetta. Lisäksi joidenkin testattavien ohjelmien havaittiin vaativan testauksessa muista poikkeavia lisätoimenpiteitä, jotka päätettiin jättää toteuttamatta työn puitteissa. Työn toivottu tulos jäi siten osittain saavuttamatta. Tuloksena syntyi kuitenkin työkalu, jolla voidaan ajaa 93 % nykyisistä esimerkkiratkaisuista määritellyillä testisyötteillä halutussa Python -ympäristössä ja saada tiedot ohjelmien toimivuudesta sekä niiden tuottamien tulosteiden täsmäävyydestä esimerkkitulosteisiin.

Object-oriented Programming Applied to the Development of Structural Analysis and Optimization Software

This paper presents the development of a two-dimensional interactive software environment for structural analysis and optimization based on object-oriented programming using the C++ language. The main feature of the software is the effective integration of several computational tools into graphical user interfaces implemented in the Windows-98 and Windows-NT operating systems. The interfaces simplify data specification in the simulation and optimization of two-dimensional linear elastic problems. NURBS have been used in the software modules to represent geometric and graphical data. Extensions to the analysis of three-dimensional problems have been implemented and are also discussed in this paper.

Issuant views of hell in contemporary Anglo-American theology

This problem of hell is a specific form of the problem of evil that can be expressed in terms of a set of putatively incompatible statements: 1. An omnipotent God could create a world in which all moral agents freely choose life with God. 2. An omnibenevolent God would not create a world with the foreknowledge that some (perhaps a significant proportion) of God’s creatures would end up in hell. 3. An omniscient God would know which people will end up in hell. 4. Some people will end up forever in hell. Since the late twentieth century, a number of British and North American philosophical theologians, inspired by C.S. Lewis, have developed a new approach to answering the problem of hell. Very little work has been done to systematize this category of perspectives on the duration, quality, purpose and finality of hell. Indeed, there is no consensus among scholars as to what such an approach should be called. In this work, however, I call this perspective issuantism. Starting from the works of a wide range of issuantist scholars, I distill what I believe to be the essence of issuantist perspectives on hell: hell is a state that does not result in universal salvation and is characterized by the insistance that both heaven and hell must issue from the love of God, an affirmation of libertarian human freedom and a rejection of retributive interpretations of hell. These sine qua non characteristics form what I have labeled basic issuantism. I proceed to show that basic issuantism by itself does not provide an adequate answer to the problem of hell. The issuantist scholars themselves, however, recognize this weakness and add a wide range of possible supplements to their basic issuantism. Some of these supplemented versions of issuantism succeed in presenting reasonable answers to the problem of hell. One of the key reasons for the development of issuantist views of hell is a perceived failure on the part of conditionalists, universalists and defenders of hell as eternal conscious torment to give adequate answers to the problem of hell. It is my conclusion, however, that with the addition of some of the same supplements, versions of conditionalism and hell as eternal conscious torment can be advanced that succeed just as well in presenting answers to the problem of hell as those advanced by issuantists, thus rendering some of the issuantist critique of non-issuantist perspectives on hell unfounded.

Phenology, fruit set and dispersal of Cordia multispicata Cham., an important weed shrub of abandoned pastures in eastern Amazonia

ABSTRACT - (Phenology, fruit set and dispersal of Cordia multispicata Cham., an important weed shrub of abandoned pastures in eastern Amazonia). The reproductive ecology of the distylous tropical shrub Cordia multispicata was studied in an abandoned pasture in Paragominas County , Pará state, Brazil. It is a common species in the Amazon basin where it occurs as a weed in open and disturbed habitats. C. multispicata has many flowers per inflorescence (85 ± 12) but 84% abort before fertilization. Flowering occurs throughout the year. Fruits are small, with a red fleshy pericarp (skin-pulp) attractive to birds. Fruit set is lower during the dry season (less than 30%) and higher during the rainy season when there are many visits of insects to the flowers. Fruiting has a peak between the end of the dry season and the middle of the rainy season. Nineteen bird species were observed foraging for the fruits of C. multispicata, and 79% of those species can be considered as potential dispersal agents. The efficient seed dispersal and aggregated spatial distribution associated with some characteristics of the dispersors greatly contributed to the success of this species in abandoned pastures of eastern Amazonia.

Flowering phenology, seed set and arthropod guilds in Trichogoniopsis adenantha (DC) (Asteraceae) in south-east Brazil

and glades. This species blooms throughout the year, attracting arthropods of various guilds, including herbivores, pollinators and predators. In this study, done over a two year period, we described the phenology of T. adenantha and assessed the seasonal variation in arthropod numbers of different guilds. We also determined the periods of lowest and highest seed set. T. adenantha population showed a peak in flowering in March-April (rainy season) with greater production of achenes in December-April. April and October had respectively highest and lowest number of fertilized, undamaged ovules, and this pattern is possibly related with population dynamics of pollinators and herbivores. In August, which was the period of greatest damage to the stigma (by geometrid larvae), there was a positive relationship between the proportion of unfertilized ovules and flowers with damaged stigma, suggesting that floral herbivory may affect reproduction in T. adenantha. We discuss the complex dynamics of the beneficial and harmful interactions between arthropods and the host plant.

Scheduling dynamic dataflow graphs with model checking

With the shift towards many-core computer architectures, dataflow programming has been proposed as one potential solution for producing software that scales to a varying number of processor cores. Programming for parallel architectures is considered difficult as the current popular programming languages are inherently sequential and introducing parallelism is typically up to the programmer. Dataflow, however, is inherently parallel, describing an application as a directed graph, where nodes represent calculations and edges represent a data dependency in form of a queue. These queues are the only allowed communication between the nodes, making the dependencies between the nodes explicit and thereby also the parallelism. Once a node have the su cient inputs available, the node can, independently of any other node, perform calculations, consume inputs, and produce outputs. Data ow models have existed for several decades and have become popular for describing signal processing applications as the graph representation is a very natural representation within this eld. Digital lters are typically described with boxes and arrows also in textbooks. Data ow is also becoming more interesting in other domains, and in principle, any application working on an information stream ts the dataflow paradigm. Such applications are, among others, network protocols, cryptography, and multimedia applications. As an example, the MPEG group standardized a dataflow language called RVC-CAL to be use within reconfigurable video coding. Describing a video coder as a data ow network instead of with conventional programming languages, makes the coder more readable as it describes how the video dataflows through the different coding tools. While dataflow provides an intuitive representation for many applications, it also introduces some new problems that need to be solved in order for data ow to be more widely used. The explicit parallelism of a dataflow program is descriptive and enables an improved utilization of available processing units, however, the independent nodes also implies that some kind of scheduling is required. The need for efficient scheduling becomes even more evident when the number of nodes is larger than the number of processing units and several nodes are running concurrently on one processor core. There exist several data ow models of computation, with different trade-offs between expressiveness and analyzability. These vary from rather restricted but statically schedulable, with minimal scheduling overhead, to dynamic where each ring requires a ring rule to evaluated. The model used in this work, namely RVC-CAL, is a very expressive language, and in the general case it requires dynamic scheduling, however, the strong encapsulation of dataflow nodes enables analysis and the scheduling overhead can be reduced by using quasi-static, or piecewise static, scheduling techniques. The scheduling problem is concerned with nding the few scheduling decisions that must be run-time, while most decisions are pre-calculated. The result is then an, as small as possible, set of static schedules that are dynamically scheduled. To identify these dynamic decisions and to find the concrete schedules, this thesis shows how quasi-static scheduling can be represented as a model checking problem. This involves identifying the relevant information to generate a minimal but complete model to be used for model checking. The model must describe everything that may affect scheduling of the application while omitting everything else in order to avoid state space explosion. This kind of simplification is necessary to make the state space analysis feasible. For the model checker to nd the actual schedules, a set of scheduling strategies are de ned which are able to produce quasi-static schedulers for a wide range of applications. The results of this work show that actor composition with quasi-static scheduling can be used to transform data ow programs to t many different computer architecture with different type and number of cores. This in turn, enables dataflow to provide a more platform independent representation as one application can be fitted to a specific processor architecture without changing the actual program representation. Instead, the program representation is in the context of design space exploration optimized by the development tools to fit the target platform. This work focuses on representing the dataflow scheduling problem as a model checking problem and is implemented as part of a compiler infrastructure. The thesis also presents experimental results as evidence of the usefulness of the approach.

Strategic narratives and competitive advantage : do winners speak differently?

Concepts, models, or theories that end up shaping practices, whether those practices fall in the domains of science, technology, social movements, or business, always emerge through a change in language use. First, communities begin to talk differently, incorporating new vocabularies (Rorty, 1989), in their narratives. Whether the community’s new narratives respond to perceived anomalies or failures of the existing ones (Kuhn, 1962) or actually reveal inadequacies by addressing previously unrecognized practices (Fleck, 1979; Rorty, 1989) is less important here than the very phenomena that they introduce differences. Then, if the new language proves to be useful, for example, because it helps the community solve a problem or create a possibility that existing narratives do not, the new narrative will begin circulating more broadly throughout the community. If other communities learn of the usefulness of these new narratives, and find them sufficiently persuasive, they may be compelled to test, modify, and eventually adopt them. Of primary importance is the idea that a new concept or narrative perceived as useful is more likely to be adopted. We can expect that business concepts emerge through a similar pattern. Concepts such as “competitive advantage,” “disruption,” and the “resource based view,” now broadly known and accepted, were each at some point first introduced by a community. This community experimented with the concepts they introduced and found them useful. The concept “competitive advantage,” for example, helped researchers better explain why some firm’s outperformed others and helped practitioners more clearly understand what choices to make to improve the profit and growth prospects of their firms. The benefits of using these terms compelled other communities to consider, apply, and eventually adopt them as well. Were these terms not viewed as useful, they would not likely have been adopted. This thesis attempts to observe and anticipate new business concepts that may be emerging. It does so by seeking to observe a community of business practitioners that are using different language and appear to be more successful than a similar community of practitioners that are have not yet begun using this different language as extensively. It argues that if the community that is adopting new types of narratives is perceived as being more successful, their success will attract the attention of other communities who may then seek to adopt the same narratives. Specifically, this thesis compares the narratives used by a set of firms that are considered to be performing well (called Winners) with those of set of less-successful peers (called Losers). It does so with the aim of addressing two questions: - How do the strategic narratives that circulate within “winning” companies and their leaders differ from those circulating within “losing” companies and their leaders? - Given the answer to the first question: what new business strategy concepts are likely to emerge in the business community at large? I expected to observe “winning” companies shifting their language, abandoning an older set of narratives for newer ones. However the analysis indicates a more interesting dynamic: “winning” companies adopt the same core narratives as their “losing” peers with equal frequency yet they go beyond these. Both “winners” and “losers” seem to pursue economies of scale, customer captivity, best practices, and securing preferential access to resources with similar vigor. But “winners” seem to go further, applying three additional narratives in their pursuits of competitive advantage. They speak of coordinating what is uncoordinated, adopting what this thesis calls “exchanging the role of guest for that of host,” and “forcing a two-front battle” more frequently than their “loser” peers. Since these “winning” companies are likely perceived as being more successful, the unique narratives they use are more likely to be emulated and adopted. Understanding in what ways winners speak differently, therefore, gives us a glimpse into the possible future evolution of business concepts.

Pollination and fruit set in pumpkin (Cucurbita pepo) by honey bees

Species of Cucurbitaceae are cultivated worldwide and are depend on bee pollination for fruit set. Field and lab experiments were conducted at Cornell University, Ithaca, NY, during 1996 and 1997 to determine "Howden" pumpkin (Cucurbita pepo L.) pollen removal and deposition by honeybees and factors relating to male flower attractiveness. Several parameters were evaluated in flowers at anthesis: (1) removal of pollen from anthers by honey bees, (2) pollen deposition on the stigma by honey bees, (3) amount of pollen on the body of honey bees, (4) fruit set after bee pollination, and (5) male flower nectary's pores and flower attractiveness. Honey bees carried between 1,050 to 3,990 pollen grains and 13,765 were removed from an anther after one visit. The amount of pollen deposited on the stigma by the honey bees varied according to the number of visits, from 53 grains with one visit, to 1,253 grains with 12 visits, and the mean number of grains in each visit varied from 53 to 230 grains. The percentage of established fruits was higher (100%) when the flowers received 12 visits of Apis mellifera, corresponding to a load 1,253 pollen grains. The attractiveness of the male flower for pollen and nectar collection was increased by the degree of opening of the access pore to the nectary in the flower.

Nonconventional amide bond formation catalysis: programming enzyme specificity with substrate mimetics

This article reports on the design and characteristics of substrate mimetics in protease-catalyzed reactions. Firstly, the basis of protease-catalyzed peptide synthesis and the general advantages of substrate mimetics over common acyl donor components are described. The binding behavior of these artificial substrates and the mechanism of catalysis are further discussed on the basis of hydrolysis, acyl transfer, protein-ligand docking, and molecular dynamics studies on the trypsin model. The general validity of the substrate mimetic concept is illustrated by the expansion of this strategy to trypsin-like, glutamic acid-specific, and hydrophobic amino acid-specific proteases. Finally, opportunities for the combination of the substrate mimetic strategy with the chemical solid-phase peptide synthesis and the use of substrate mimetics for non-peptide organic amide synthesis are presented.

Omistuksen tavoitteellisuus perheyrityksissä - kartoitus omistamisen tavoitteista ja tavoitteiden määrittelystä

Suomi tarvitsee menestyviä yrittäjiä, uusia yrityksiä, kasvuyrityksiä ja kansainvälistymistä. Yrittä-jyydelle asetetaankin suuria odotuksia. Suurin huomio yrittäjyyden tarkastelussa on kuitenkin keskittynyt liiketoimintojen kehittämiseen – sen sijaan omistajuuden ja yrittäjyyden yhteyttä ei ole juurikaan huomioitu. Tämän seurauksena myös omistajuuden vaikutusta yrityksen kehittymi-seen ja menestykseen on analysoitu vähän. Edistääkseen yrityksen kehittymistä, tulee omistuksen olla tavoitteellista. Omistamisen tavoittei-den tarkastelu on kuitenkin harvinaista ja parhaimmillaankin yksiulotteista: omistamisen tavoit-teiden nähdään liittyvän lähes yksinomaan taloudellisiin tavoitteisiin, ja tavoitteiden moninaisuus unohdetaan. Tässä tutkimuksessa tarkastellaan suomalaisten perheyrittäjien omistamisen tavoit-teellisuutta, tavoitteiden määrittelyä sekä omistajaohjauksen keinoja, lähinnä hallituksen roolia, omistukseen liittyvien ratkaisujen tekijänä. Tutkimushankkeen aineisto kerättiin EK:n ja Perheyritysten liiton jäsenyrityksistä. Aineisto kerät-tiin joulukuussa 2013 ja tammikuussa 2014 web-pohjaisella kyselyllä ja siihen vastasi määräajan kuluessa 332 vastaajaa. Vastaajista perheyrityksiä oli 241 kpl. Tarkemman analyysin kohteeksi jäi 233 perheyritystä. Tutkimuksen tulokset osoittavat, että suomalaisten yrittäjien omistajuuteen liittyvät tavoitteet ovat monipuolisempia kuin yleisesti oletetaan. Puhtaasti taloudellisiin motiiveihin perustuvan yri-tysten omistamisen ohella liiketoimintaan kohdistuva mielenkiinto ja halu toimia yrittäjänä ovat merkittäviä omistamisen vaikuttimia. Suuri joukko yritysten omistajista ei kuitenkaan tietoisesti pohdi omistamisen tavoitteita vaan omistuksen tavoitteet määrittyvät liiketoiminnan tavoitteiden tai totuttujen tapojen ja perinteiden kautta. Osalla yritysten omistajista omistus muuttuu tavoit-teellisemmaksi yrityksen kehittyessä ja omistajajoukon kasvaessa. Ensimmäisen sukupolven yrittäjät näyttävät toimivan ennen kaikkea yrittäjäideologian mukaisesti pyrkien kasvattamaan yritystä ja painottaen liiketaloudellisia arvoja päätöksenteossa. Yritystoi-minnan kehittyessä ja sukupolvien lisääntyessä yrityksen omistamiseen liittyvät tavoitteet moni-puolistuvat ja monimutkaistuvat, eivätkä enää perustu pelkästään liiketoiminnallisiin menes-tysodotuksiin. Hallitustoiminnan aktivointi aktivoi myös omistuksen tavoitteellisuuden kehittymistä. Omistus-pohjan hajaantuminen lisää tarvetta erilaisten omistajaohjauksen mekanismien hyödyntämiselle. Hallituksella näyttää olevan rooli omistusratkaisuiden arvioinnissa sekä yrityksen operatiiviseen toimintaan liittyvissä omistusratkaisuissa, mutta myös läheisemmin omistamiseen ja omistajapoh-jaan liittyvissä omistusratkaisuissa. Perheomistukseen liittyvien tavoitteiden huomioiminen on tärkeää perheyrityksen hallituksen toiminnassa myös yrityksen toiminnan vakiintuessa. Sen sijaan, että perheeseen liittyvät omista-misen tavoitteet katoaisivat yrityksestä, muuttuu niiden määrittely tietoisemmaksi ja osaksi yri-tyksen hallintoa. Määräysvallan merkitys tavoitteena pienenee, kun omistajan etäisyys operatiivi-sesta toiminnasta, tai sen johtamisesta kasvaa. Tutkimuksen tulokset kertovat omistamisen tavoitteista ja tavoitteiden määrittelystä. Selvityksen lopussa luotiin määritelmä päämäärätietoiselle omistajalle: Päämäärätietoinen omistaja on omista-ja, joka tietoisesti pohtii tavoitteita omistamiselleen sekä käyttää aktiivisesti omistajavaltaansa valitsemiensa päämäärien saavuttamiseksi.

Linguistic models for decision support

Linguistic modelling is a rather new branch of mathematics that is still undergoing rapid development. It is closely related to fuzzy set theory and fuzzy logic, but knowledge and experience from other fields of mathematics, as well as other fields of science including linguistics and behavioral sciences, is also necessary to build appropriate mathematical models. This topic has received considerable attention as it provides tools for mathematical representation of the most common means of human communication - natural language. Adding a natural language level to mathematical models can provide an interface between the mathematical representation of the modelled system and the user of the model - one that is sufficiently easy to use and understand, but yet conveys all the information necessary to avoid misinterpretations. It is, however, not a trivial task and the link between the linguistic and computational level of such models has to be established and maintained properly during the whole modelling process. In this thesis, we focus on the relationship between the linguistic and the mathematical level of decision support models. We discuss several important issues concerning the mathematical representation of meaning of linguistic expressions, their transformation into the language of mathematics and the retranslation of mathematical outputs back into natural language. In the first part of the thesis, our view of the linguistic modelling for decision support is presented and the main guidelines for building linguistic models for real-life decision support that are the basis of our modeling methodology are outlined. From the theoretical point of view, the issues of representation of meaning of linguistic terms, computations with these representations and the retranslation process back into the linguistic level (linguistic approximation) are studied in this part of the thesis. We focus on the reasonability of operations with the meanings of linguistic terms, the correspondence of the linguistic and mathematical level of the models and on proper presentation of appropriate outputs. We also discuss several issues concerning the ethical aspects of decision support - particularly the loss of meaning due to the transformation of mathematical outputs into natural language and the issue or responsibility for the final decisions. In the second part several case studies of real-life problems are presented. These provide background and necessary context and motivation for the mathematical results and models presented in this part. A linguistic decision support model for disaster management is presented here – formulated as a fuzzy linear programming problem and a heuristic solution to it is proposed. Uncertainty of outputs, expert knowledge concerning disaster response practice and the necessity of obtaining outputs that are easy to interpret (and available in very short time) are reflected in the design of the model. Saaty’s analytic hierarchy process (AHP) is considered in two case studies - first in the context of the evaluation of works of art, where a weak consistency condition is introduced and an adaptation of AHP for large matrices of preference intensities is presented. The second AHP case-study deals with the fuzzified version of AHP and its use for evaluation purposes – particularly the integration of peer-review into the evaluation of R&D outputs is considered. In the context of HR management, we present a fuzzy rule based evaluation model (academic faculty evaluation is considered) constructed to provide outputs that do not require linguistic approximation and are easily transformed into graphical information. This is achieved by designing a specific form of fuzzy inference. Finally the last case study is from the area of humanities - psychological diagnostics is considered and a linguistic fuzzy model for the interpretation of outputs of multidimensional questionnaires is suggested. The issue of the quality of data in mathematical classification models is also studied here. A modification of the receiver operating characteristics (ROC) method is presented to reflect variable quality of data instances in the validation set during classifier performance assessment. Twelve publications on which the author participated are appended as a third part of this thesis. These summarize the mathematical results and provide a closer insight into the issues of the practicalapplications that are considered in the second part of the thesis.

Enhancement of declarative memory associated with emotional content in a Brazilian sample

Several studies have documented that emotional arousal may enhance long-term memory. This is an adaptation of a paradigm previously used in North American and European samples in investigations of the influence of emotion on long-term retention. A sample of 46 healthy adults of high and low educational levels watched a slide presentation of stories. A randomly assigned group watched a story with an arousing content and another group watched a neutral story. The stories were matched for structure and comprehensibility and the set and order of the 11 slides were the same in both conditions. Immediately after viewing the slide presentation, the participants were asked to rate the emotionality of the narrative. The arousing narrative was rated as being more emotional than the neutral narrative (t (44) = -3.6, P<0.001). Ten days later subjects were asked to remember the story and answer a multiple-choice questionnaire about it. The subjects who watched the arousing story had higher scores in the free recall measure (t (44) = -2.59, P<0.01). There were no differences between groups in the multiple-choice test of recognition memory (t (44) = 0.26). These findings confirm that an emotional arousing content enhances long-term declarative memory and indicate the possibility of applying this instrument to clinical samples of various cultural backgrounds.
