Abstract: From 2012 to 2013 were surveyed gastrointestinal parasites from pig farms located in different municpaliyies in the state of Rio de Janeiro. Fecal samples from 790 pigs were collected from the rectum on 88 family farms and 702 farms with industrial production. The samples were subjected to Faust et al., Sheather, Ritchie, Lutz and direct examination faecal techniques. The estimated parasite prevalence was 93.1% in family farms and 59.1% in industrial farms. Balantidium coli, coccidia and Entamoeba sp. were the parasites with the highest frequencies, and the male and female reproductive categories and fatteners pigs the most infected (p<0.05). Trophozoites of B. coli were most evident in stool samples from semi-solid followed by solid and diarrheal consistencies. Strongyles eggs and Trichuris suis have been detected exclusively in family farms. Ascaris suum eggs and Strongyloides ransomi showed low frequency. The high degree of parasitism, especially protozoa, indicates the need to reassess the management of pigs in both types of production.

Vesilaitokset kuluttavat merkittäviä määriä energiaa, johon on alettu kiinnittää huomiota viime vuosina. Energiatehokkuuden edistämisen hidasteeksi on noussut puutteellinen tietohuolto sekä vesilaitosten yhteisten tunnuslukujen ja kriteerien puuttuminen. Diplomityön tavoitteena on selvittää tietohuollon ongelmia Tampereen Vedellä. Työn tavoitteena on myös tutkia veden tuotannon ja jakelun energiatehokkaiden ohjaustapojen löytämistä tietohuollon ja tunnuslukujen avulla. Työssä käytetyt metodologiat ovat Tampereen Veden työntekijöiden haastattelut, prototyypin analysointi sekä vedenottamoiden ominaisenergiaan liittyvien mittauspisteiden läpikäynti. Diplomityön tuloksena saatiin laaja kuva Tampereen Veden tietohuoltoon liittyvistä ongelmista. Merkittävimmät tietohuollon haasteet liittyvät työntekijöihin, järjestelmiin sekä mittauspisteiden puuttumiseen. Mittauspisteet ja niiden tallentuminen ovat edellytys tunnuslukujen luomiselle. Tunnuslukuja voidaan hyödyntää energiatehokkaiden ohjaustapojen löytämiseksi, mutta vesilaitosten yhteiset kriteerit tunnusluvuille puuttuvat. Energiatehokkuustunnuslukuja on tarve tutkia lisää ja kehittää yhteistyötä vesilaitosten välillä tunnuslukujen luomiseksi sekä vertailutietojen saamiseksi.

Enabling Change in Universities: Enhancing Education for Sustainable Development with Tools for Quality Assurance This thesis deals with enabling change in universities, more explicitly enhancing education for sustainable development with tools for quality assurance. Change management is a discipline within management that was developed in the 1980s because business changed from being predictable to unpredictable. The PEST mnemonic is a method to categorize factors enabling change; such as political, economic, socio-cultural and technological factors, which all affect higher education. A classification of a change, in either hard or soft, can help understanding the type of change that an organization is facing. Hard changes are more applied to problems that have clear objectives and indicators, with a known cause of the problem. Soft changes are applied to larger problems that affect the entire organization or beyond it. The basic definition for sustainable development is: the future generations should have similar opportunities as the previous. The UN has set as a global goal an integration of education for sustainable development (ESD) at all levels of education during 2005- 2014. The goal is set also in universities, the graduates of which are future leaders for all labor markets. The objective for ESD in higher education is that graduates obtain the competence to take economic, social and environmental costs and benefits into account when making decisions. Knowledge outcomes should aim for systematic and holistic thinking, which requires cross disciplinary education. So far, the development of ESD has not achieved its goals. The UN has identified a need for more transdisclipnary research in ESD. A joint global requirement for universities is quality assurance, the aim of which is to secure and improve teaching and learning. Quality, environmental and integrated management systems are used by some universities for filling the quality assurance requirements. The goal of this thesis is to open up new ways for enhancing ESD in universities, beyond the forerunners; by exploring how management systems could be used as tools for promoting ESD. The thesis is based on five studies. In the first study, I focus on if and how tools for quality assurance could be benefitted for promoting ESD. It is written from a new perspective, the memetic, for reaching a diversity of faculty. A meme is an idea that diffuses from brain to brain. It can be applied for cultural evolution. It is a theory that is based on the evolutionary theory by Darwin, applied for social sciences. In the second Paper, I present the results from the development of the pilot process model for enhancing ESD with management systems. The development of the model is based on a study that includes earlier studies, a survey in academia and an analysis of the practice in 11 universities in the Nordic countries. In the third study, I explore if the change depends on national culture or if it is global. It is a comparative study on both policy and implementation level, between the Nordic countries and China. The fourth study is a single case study based on change management. In this study, I identify what to consider in order to enable the change: enhancing ESD with tools for quality assurance in universities. In the fifth Paper, I present the results of the process model for enhancing ESD with management systems. The model was compared with identified drivers and barriers for enhancing ESD and for implementing management systems. Finally, the process model was piloted and applied for identifying sustainability aspects in curricula. Action research was chosen as methodology because there are not already implemented approaches using quality management for promoting ESD, why the only way to study this is to make it happen. Another reason for choosing action research is since it is essential to involve students and faculty for enhancing ESD. Action based research consists of the following phases: a) diagnosing, b) planning action, c) taking action and d) evaluating action. This research was made possible by a project called Education for Sustainable Development in Academia in the Nordic countries, ESDAN, in which activities were divided into these four phases. Each phase ended with an open seminar, where the results of the study were presented. The objective for the research project was to develop a process for including knowledge in sustainable development in curricula, which could be used in the quality assurance work. Eleven universities from the Nordic countries cooperated in the project. The aim was, by applying the process, to identify and publish examples of relevant sustainability aspects in different degree programs in universities in the Nordic countries. The project was partly financed by the Nordic Council of Ministers and partly by the participating pilot universities. Based on the results of my studies, I consider that quality, environmental and integrated management systems can be used for promoting ESD in universities. Relevant sustainability aspects have been identified in different fields of studies by applying the final process model. The final process model was compared with drivers and barriers for enhancing ESD and for implementing management systems in universities and with succeeding with management systems in industry. It corresponds with these, meaning that drivers are taken into account and barriers tackled. Both ESD and management systems in universities could be considered successful memes, which can reflect an effective way of communication among individuals. I have identified that management systems could be used as tools for hard changes and to support the soft change of enhancing ESD in universities with management system. Based on the change management study I have summarized recommendations on what to consider in order to enable the studied change. The main practical implications of the results are that the process model could be applied for assessment, benchmarking and communication of ESD, connected to quality assurance, when applied. This is possible because the information can be assembled in one picture, which facilitates comparison. The memetic approach can be applied for structuring. It is viable to make comparative studies between cultures, for getting insight in special characteristics of the own culture. Action based research is suitable for involving faculty. Change management can be applied for planning a change, which both enhancing ESD and developing management systems are identified to be.

ABSTRACT The increase in the area planted with Crotalaria spectabilishas occurred by several factors, highlighting the potential to reduce the nematodes, nitrogen fixation and the high production of biomass. By becoming a species sown as a crop, it is necessary to control the weeds that coexist with showy crotalaria. This change in the use of this crop creates the possibility of this specie becoming a weed. The aim of this study was to assess the potential use of herbicides applied in preemergence and postemergence of C.spectabilisfor different purposes (control of volunteer and selectivity plants). Three experiments were installed in a greenhouse (two with herbicides applied in preemergence - in soils with distinct textural categories; and one experiment with herbicides applied in postemergence). The results of the experiments with herbicides applied in preemergence showed that: amicarbazone, atrazine, diuron, metribuzin, prometryn, fomesafen and sulfentrazone showed effectiveness for control of C.spectabilis in clayey soil. Besides these, flumioxazin and isoxaflutole also showed potential to be used in the control of showy crotalaria in soils with loam texture. In relation to the postemergence herbicides, atrazine, diuron, prometryn, flumioxazin, fomesafen, lactofen, saflufenacil, amonio-glufosinate and glyphosate can be used aiming the chemical control of C.spectabilis. Herbicides chlorimuron-ethyl, diclosulan, imazethapyr, pyrithiobac-sodium, trifloxysulfuron-sodium, clomazone, pendimethalin, S-metolachlor and trifluralin applied in preemergence, and imazethapyr, pyrithiobac-sodium, flumiclorac, bentazon and clethodim applied in postemergence caused low levels of injury to C.spectabilis plants, making necessary the development of new searches to ensure the selectivity of these products.

Yritys voi kasvattaa liiketoimintaansa joko nykyisillä tai uusilla tuotteilla nykyisillä tai uusilla markkinoilla. Kasvua voidaan hakea joko sisäisellä kehittämisellä, yritysostoin tai strategisin sopimusjärjestelyin. Kasvun suunnan valitseminen vaatii tuotteiden ja tuoteryhmien markkinoiden tutkimista, jotta yritys löytää markkinoiltaan houkuttelevimmat tuotteet. Tutkimuksessa kartoitetaan valittujen nykyisten ja uusien tuotteiden markkinoiden houkuttelevuutta. Houkuttelevuuteen vaikuttaa eritoten alan kilpailutilanne ja markkinakysyntä. Kilpailua kartoitettaessa on tutkittu tuotteiden tai tuoteryhmien kilpailijoita, korvaavia tuotteita ja niiden toimittajia, jakelukanavia, uusien alalle tulijoiden uhkaa sekä asiakkaiden ostomotiiveja. Markkinakysyntää ja sen kehitystä on tutkittu nykyisten toimittajien liikevaihtojen, haastatteluiden ja epämuodollisten keskusteluiden kautta. Diplomityössä on esitelty tehty tutkimus ja tutkimuksella kerätty tieto kunkin tuoteryhmän kohdalla. Työn lopussa on tehty analyysit valittujen tuotteiden markkinoista ja niiden houkuttelevuudesta työn teettäneen yrityksen näkökulmasta. Tämän jälkeen on esitetty suositellut toimet yritykselle, mikäli se päättää kartoitettujen tuotteiden olevan sen tulevaisuuden kasvun suunta.

Reports of uterine cancer deaths that do not specify the subsite of the tumor threaten the quality of the epidemiologic appraisal of corpus and cervix uteri cancer mortality. The present study assessed the impact of correcting the estimated corpus and cervix uteri cancer mortality in the city of São Paulo, Brazil. The epidemiologic assessment of death rates comprised the estimation of magnitudes, trends (1980-2003), and area-level distribution based on three strategies: i) using uncorrected death certificate information; ii) correcting estimates of corpus and cervix uteri mortality by fully reallocating unspecified deaths to either one of these categories, and iii) partially correcting specified estimates by maintaining as unspecified a fraction of deaths certified as due to cancer of "uterus not otherwise specified". The proportion of uterine cancer deaths without subsite specification decreased from 42.9% in 1984 to 20.8% in 2003. Partial and full corrections resulted in considerable increases of cervix (31.3 and 48.8%, respectively) and corpus uteri (34.4 and 55.2%) cancer mortality. Partial correction did not change trends for subsite-specific uterine cancer mortality, whereas full correction did, thus representing an early indication of decrease for cervical neoplasms and stability for tumors of the corpus uteri in this population. Ecologic correlations between mortality and socioeconomic indices were unchanged for both strategies of correcting estimates. Reallocating unspecified uterine cancer mortality in contexts with a high proportion of these deaths has a considerable impact on the epidemiologic profile of mortality and provides more reliable estimates of cervix and corpus uteri cancer death rates and trends.

Arvoverkostojen välinen kilpailu nykyisessä liiketoiminnassa on johtanut siihen, että toimittajaportfolioita pyritään hallitsemaan yhä strategisemmin. Yksi tapa hallita yrityksen toimittajaportfoliota on segmentoida toimittajat eri kategorioihin ja asettaa näille kategorioille strategiset tavoitteet. Segmentoinnin työkaluina voidaan käyttää ostoportfolioita, joita on suunniteltu useita erilaisia erilaisiin tarpeisiin. Käytetyin portfoliomalli on Kraljicin ostoportfolio, jota käytetään visualisoimaan yrityksen toimittajia ja tuotteita niiden tuottovaikutuksen ja toimitusriskin perusteella. Tutkimuksen tavoite oli ymmärtää, miten hankinta-alan asiantuntijat hallitsevat toimittajaportfoliotaan, painottaen erityisesti sitä, miten hankinta-asiantuntijat käyttävät tieteellisiä ostoportfolioita todellisessa liike-elämässä. Tutkimus toteutettiin laadullisin menetelmin, koska työn tarkoituksena oli ymmärtää syvällisesti tutkittavia kohteita ja pohtia niitä taustatekijöitä, jotka puoltavat tai hidastavat ostoportfolioiden käyttöä yrityksissä. Työssä haastateltiin viittä hankinta-alan asiantuntijaa, joista kaksi työskentelee johtavissa tehtävissä yksityisessä osakeyhtiössä ja kolme työskentelee johtavissa tehtävissä julkisessa osakeyhtiössä. Työn lopputuloksena voidaan todeta, että Kraljicin ostoportfoliota käytetään laajasti erilaisissa hankinnoissa, mutta muita tieteellisiä malleja ei käytetä. Portfolionanalyysin käyttö liittyy usein hankintaosaston kokoon, hankintahenkilöstön asiantuntevuuteen ja koulutukseen, strategisuuteen ja strategiseen vaikutusvaltaan yrityksessä. Niiden käyttö riippuu myös siitä, minkälaisia hankintoja tehdään. Haastavimmaksi ostoportfolioiden käyttö koetaan palveluiden hankinnoissa. Portfoliomallia hyödynnetään erityisesti, kun yritys kartoittaa toimittajakenttäänsä hakiessaan uusia muutossuuntia liiketoimintaansa.

Since 2008, One of the International Accounting Standards Board’s (IASB) objective has been to replace the old IAS 39 – Financial Instruments standard. IASB achieved this objective in July 2014 when they published the new IFRS 9 – Financial Instruments after many phases. In this study, the main purpose was to find out how the Big Four – audit entities have welcomed the different reforms which IFRS 9 brings to the treatment of financial instruments in the financial statements. Alongside with this, the study presents a short overview to the common attitude towards the new standard. The study proceeds so that the most siginificant reforms have been divided into three main categories and inside of these more precisely to single reforms. This study is based on the qualitative research method. The empirical data of the study consists of comment letters by the Big Four – entities, which have been sent to the IASB regarding Exposure Drafts (ED) of IFRS 9. In total IASB received 757 comment letters regarding to the specific EDs. In this study the population were restricted to 16 comment letters sent by the Big Four – entities. The data is available at IFRS Foundation’s website. According to the research results Big Four – entities think that the reforms which IFRS 9 brings are mainly welcome. In its entirety Big Four – entities consider IFRS 9 better than its predecessor IAS 39. There were differnces in opinions towards IFRS 9 and specific reforms among the Big Four - entities. According to the findings the best reforms were related to the efficiency demands of hedge accounting and to impairments and the valuation of credit losses. The least popular reforms were the reforms regarding the measurement of financial assets and liabilities; more specifically fair value option and the reforms concerning equity instruments were viewed as most challenging.

Tämän kandidaatintutkielman tarkoituksena oli selvittää minkälaisia liiketoiminnallisia mahdollisuuksia ja haasteita Big Dataan ja sen ominaispiirteisiin liittyy, ja miten Big Data määritellään nykyaikaisesti ja ajankohtaisesti. Tutkimusongelmaa lähestyttiin narratiivisen kirjallisuuskatsauksen keinoin. Toisin sanoen tutkielma on hajanaisen tiedon avulla koostettu yhtenäinen katsaus nykytilanteeseen. Lähdeaineisto koostuu pääosin tieteellisistä artikkeleista, mutta käytössä oli myös oppikirjamateriaalia, konferenssijulkaisuja ja uutisartikkeleja. Tutkimuksessa käytetyt akateemisen kirjallisuuden lähteet sisälsivät keskenään paljon samankaltaisia näkemyksiä tutkimusaihetta kohtaan. Niiden perusteella muodostettiin kaksi taulukkoa havaituista mahdollisuuksista ja haasteista, ja taulukoiden rivit nimettiin niitä kuvaavien ominaispiirteiden mukaan. Tutkimuksessa liiketoiminnalliset mahdollisuudet ja haasteet jaettiin viiteen pääkategoriaan ja neljään alakategoriaan. Tutkimus toteutettiin liiketoiminnan näkökulmasta, joten siinä sivuutettiin monenlaisia Big Datan teknisiä aspekteja. Tutkielman luonne on poikkitieteellinen, ja sen avulla pyritään havainnoimaan tämän hetken yhtä uusinta tietojenkäsittelykäsittelytieteiden termiä liiketoiminnallisessa kontekstissa. Tutkielmassa Big Dataan liittyvillä ominaispiirteillä todettiin olevan mahdollisuuksia, jotka voitiin jaotella korrelaatioiden havaitsemisen perusteella markkinoiden tarkemman segmentoinnin mahdollisuuksiin ja päätöksenteon tukena toimimiseen. Reaaliaikaisen seurannan mahdollisuudet perustuvat Big Datan nopeuteen ja kokoon, eli sen jatkuvaan kasvuun. Ominaispiirteisiin liittyvät haasteet voidaan jakaa viiteen kategoriaan, joista osa liittyy toimintaympäristöön ja osa organisaation sisäiseen toimintaan.

This qualitative research project uses a Deleuzo-Guattarian theoretical framework to address the question: “How are the politically oriented social forums in Gaia Online experienced as a continuum of overlapping of lines, including molar lines, lines of flight, and molecular lines?” Although smooth lines of flight may occur in Gaia, there are always mechanisms that work to re-territorialize them as more striated molar operations. Conversely, while more striated molar lines may be evident in Gaia, there are also smooth lines of flight that attempt to deterritorialize them as smooth space. Founded in 2003, Gaia is a virtual community in which members use 3D avatars to socialize with others, create content, and play games. Deleuze and Guattari (1987) have defined space with three systems: on one end is state-oriented static space, on the other end is nomadic fluid space, and situated in the middle is molecular space which contains both smooth and striating elements. While state-oriented striated space is based on routines, rules, and specifications, nomadic smooth space is flexible, always changing, and full of possibility. Some of the smoother operations that are evident in Gaia include becoming other, decentred communications, desire as resistance, and lines of flight. Some of the more striated operations include social reproduction of gender norms/expectations, capitalist mechanisms, violence and intolerance linked to categories and binaries (racism/sexism/ageism), the regulation of desire, and the organisation of bodies.

Heyting categories, a variant of Dedekind categories, and Arrow categories provide a convenient framework for expressing and reasoning about fuzzy relations and programs based on those methods. In this thesis we present an implementation of Heyting and arrow categories suitable for reasoning and program execution using Coq, an interactive theorem prover based on Higher-Order Logic (HOL) with dependent types. This implementation can be used to specify and develop correct software based on L-fuzzy relations such as fuzzy controllers. We give an overview of lattices, L-fuzzy relations, category theory and dependent type theory before describing our implementation. In addition, we provide examples of program executions based on our framework.

This thesis examined the impact of the Canada Not-for-Profit Corporations Act (2009) on the governance of national sport organizations (NSO). The impact of the legislation was explored through the perceptions of NSO executive leaders and by analyzing the by-laws in effect before the legislation. The legislation was perceived to have the greatest impact on enhancing accountability, specifically affecting membership categories and director selection. The interview data showed that the legislation was necessary to enhance accountability in many NSOs. The Respondents also demonstrated that they understood the goals sought through the legislation. The data also showed that the boards of NSOs were already in alignment with the goals of the legislation. With respect to governance, the data indicated that NSOs rely almost exclusively on their regional sport associations as voting stakeholders. An emerging issue that came out of the results was the role of athletes in the governance of sport organizations.
