Elevers läs- och skrivförmåga över tid : en longitudinell kohortstudie av läsförståelse och stavning i årskurs 1-6 i en finlandssvensk skola

Reports have shown that a growing number of students are leaving school without adequate reading and writing skills. At the same time, finnish children have improved in reading lit-eracy over the past decade. The school´s primary mission is to support student´s reading and writing development and follow it over time. Not only individual students´development has to be followd over time, as seen in this study, to be able to plan interventions. The purpose of this licentiate thesis is to study how the results in grades 1–6 exhibit in reading compre-hension and spelling over time in a school for the Swedish-speaking minority in Finland. Even gender differences in reading comprehension and spelling are being examined, as well as students with low performance. The data collection has been done during a period of twelwe years, 1997–2009, where data from practically every two years has been used for this study. Results are reported for the years 1997, 2000, 2001, 2003, 2007 and 2009. The measuring instruments are standardized and normative tests in reading comprehension and spelling. The same instruments were used all of the years. The number of students was 1 037 and when possible, students partici-pated more than once. There was a minimal loss of data. The groups of students mostly came from urban districts, and a smaller number came from rural districts. Students with special needs were included in the group, but none of the students in special units participat-ed. The results show that the skills in reading comprehension and spelling haven´t changed appreciably over time. The trend shows slightly positive or unchanged direction except in spelling in grade 1 and reading comprehension in grade 5 where the trend is slightly nega-tive. The most obvious change can be noticed over time in reading comprehension in grade 2, where performance has improved significantly. Significant differences between boys´and girls´performances occur some years and in favor of the girls, but more often in spelling than in reading comprehension. In grade 4, there are no differences in results between boys and girls in any year, neither in reading comprehension nor in spelling, nor in grade 2 in reading comprehension. When the results shows gender differences, there are always differ-ences in both reading comprehension and spelling. Poor performances are also analyzed over time. Isolated reading comprehension difficulties were common for those who was performing poorly. In grade 2, as the only grade, most common was a double deficit in both reading comprehension and spelling, and in grade 4, most students who performed poorly had isolated difficulties in spelling. The amount of poor results varies over time, and no particular trend can be discerned. In grade 2, however, the poor results decreased over time, especially for the boys. Even in reading comprehension for grade 6 the amount of poor results, especially for the boys (10th percentile), has decreased over time, at least in the later years, while the poor results in-creased in spelling generally. In grade 4 the amount of poor results in spelling (10th perc.) seems to be reduced for the girls.

Management of Soft Information in Sales and Operations Planning

With a Sales and Operations Planning (S&OP) process, a company aims to manage the demand and supply by planning and forecasting. The studied company uses an integrated S&OP process to improve the company's operations. The aim of this thesis is to develop this business process by finding the best possible way to manage the soft information in S&OP, whilst also understanding the importance and types (assumptions, risks and opportunities) of soft information in S&OP. The soft information in S&OP helps to refine future S&OP planning, taking into account the uncertainties that affect the balance of the long-term demand and supply (typically 12-18 months). The literature review was used to create a framework for soft information management process in S&OP. There were not found a concrete way how to manage soft information in the existing literature. In consequence of the poor literature available the Knowledge Management literature was used as the base for the framework creation, which was seen in the very same type of information management like the soft information management is. The framework created a four-stage process to manage soft information in S&OP that included also the required support systems. First phase is collecting and acquiring soft information in S&OP, which include also categorization. The categorization was the cornerstone to identify different requirements that needs to be taken into consideration when managing soft information in S&OP process. The next phase focus on storing data, which purpose is to ensure the soft information is managed in a common system (support system) in a way that the following phase makes it available to users in S&OP who need by help of sharing and applications process. The last phase target is to use the soft information to understand assumptions and thoughts of users behind the numbers in S&OP plans. With this soft management process the support system will have a key role. The support system, like S&OP tool, ensures that soft information is stored in the right places, kept up-to-date and relevancy. The soft information management process in S&OP strives to improve the relevant soft information documenting behind the S&OP plans into the S&OP support system. The process offers an opportunity to individuals to review, comment and evaluate soft information in S&OP made by their own or others. In the case company it was noticed that without a properly documented and distributed soft information in S&OP it was seen to cause mistrust towards the planning.

Palvelusetelien prosessit ja hallinnolliset kustannukset Helsingin kaupungin sosiaali- ja terveysvirastossa

Diplomityö käsittelee Helsingin sosiaali- ja terveysviraston palvelusetelitoimintaa eräänä ostopalvelun järjestämistapana. Vakinaistettuja palveluseteleitä on kaksi-toista, joista työhön on valittu viisi kustannuksiltaan ja lukumääriltään suurinta palveluseteliä. Tutkimuksessa mallinnetaan kahden keskenään erilaisimman palve-lusetelin prosessikuvaukset, vanhusten palveluasumisen (sosh) ja suun terveyden-huollon (tervh) palveluseteleille ja kuvataan niiden hallinnolliset työvaiheet ja toi-minnot. Empiirinen aineisto koostuu aiemmin kerätystä hallinnollisen työajan da-tasta, jonka avulla eri toimintoihin sitoutuneiden hallinnollisten kustannuksien las-kenta on suoritettu hyödyntäen aikaperusteista toimintolaskentaa. Aikaperusteisen toimintolaskennan avulla saadaan esille kirjanpidon ulkopuolelle jääviä piileviä prosessikustannuksia. Lisäksi diplomityössä tehdään edullisuusvertailua oman vas-taavan palvelutoiminnan ja palvelusetelien välillä. Terveydenhuollon palvelusetelien hallinnolliset prosessit osoittautuvat hallinnolli-sesti ja kustannuksien osalta kuormittavammaksi kuin sosiaalihuollon vastaavat prosessit. Terveydenhuollon palveluseteliprosessit ovat luonteeltaan monivaihei-sempia, ne ovat toimenpiteellisiä ja kertaluonteisia, joka lisää asiakasvolyymia ja tiedon välittämisen tarvetta sosiaali- ja terveysviraston ja palveluntuottajan välillä. Hallinnollinen kustannuslisä on vuoden 2013 palvelusetelitoiminnan volyymeillä suun terveydenhuollossa +24%, kolonoskopiassa +9%, ikäihmisten päivätoimin-nassa +8%, vammaisten henkilökohtaisessa avussa +5% ja vanhusten palveluasu-misessa +1%. Hallinnollisten kustannusten esiin tuomiseksi tulee terveydenhuollon palvelusetelien kirjanpidon kustannuksissa käyttää kerrointa 1,167 ja sosiaalihuol-lon palvelusetelien kustannuksissa kerrointa 1,046. Edullisuusvertailussa suun terveydenhuollon ja kolonoskopian palvelusetelit osoittautuvat omaa toimintaa kalliimmiksi, vanhusten palveluasuminen, ikäihmisten päivätoiminta ja vammais-ten henkilökohtainen apu on edullisempaa tuottaa palvelusetelillä. Palveluseteli-toiminnan kustannushyöty ei ole ainoa tekijä toimintaa suunnitelleessa. Hoitota-kuuseen vastaaminen, asiakasorientaation ja vapaavalintaisuuden lisääntyminen, sekä palvelun sujuvuus vaikuttavat myös palvelusetelitoiminnan kehittämisessä.

Tuotantokoneiden pitoajat meijerialan yrityksessä

Diplomityön tavoitteena on tutkia, millaisia ovat Valion tuoretuotemeijerien tuotantokoneiden toteutuneet pitoajat suhteessa kirjanpidon pitoaikaan ja mikä pitoaikoihin eniten vaikuttaa. Tuotantokoneiksi luetaan tässä tutkimuksessa valmistus- ja pakkauskoneet sekä pakkauskoneiden jälkikäsittelylaitteet. Tavoitteena on selvittää myös eroja eri laiteryhmien ja meijerien välillä, ja mitkä syyt aiheuttavat nämä erilaiset pitoajat. Tutkimus toteutettiin sekä haastattelututkimuksena että taseeseen ja erillisiin konetietoihin tutustumalla. Tärkeimpinä käytettävinä teorioina on hyödynnetty erilaisten pitoaikojen määritelmiä sekä koneiden korvausmalleja sekä muita tutkimuksia pitoajoista. Vanhimmat valmistuskoneet olivat Tampereella ja uusimmat Jyväskylässä. Pakkauskoneista vanhimmat ovat Riihimäellä ja uusimmat vastaavasti Jyväskylässä sekä Tampereella. Jälkikäsittelylaitteista vanhimmat laitteet olivat Tampereella ja uusimmat Riihimäellä. Kokonaisuudessaan laitoksista nuorin on Jyväskylän meijeri, mihin merkittävin syy on koko prosessin uusiminen vuonna 2003. Tutkimuksessa kokonaispitoaika tuotantokoneille oli 10,8 vuotta. Yleisimpiä syitä jonkin laitteen vaihtamiseen meijereillä olivat pelko hygienian riittämättömyydestä, laitteen huonontunut kunto ja varaosien huono saatavuus. Tutkittujen Valion laitoksien tuotantokoneet ovat hyvin samanikäisiä verrattuna muiden tutkimuksien tuloksiin. Jatkossa Valion kannattaisi kehittää pitoaikojen seurantaa ja vuosittaisia tarkastuksia meijereillä.

Advanced biofuel production: Engineering metabolic pathways for butanol and propane biosynthesis.

Greenhouse gases emitted from energy production and transportation are dramatically changing the climate of Planet Earth. As a consequence, global warming is affecting the living conditions of numerous plant and animal species, including ours. Thus the development of sustainable and renewable liquid fuels is an essential global challenge in order to combat the climate change. In the past decades many technologies have been developed as alternatives to currently used petroleum fuels, such as bioethanol and biodiesel. However, even with gradually increasing production, the market penetration of these first generation biofuels is still relatively small compared to fossil fuels. Researchers have long ago realized that there is a need for advanced biofuels with improved physical and chemical properties compared to bioethanol and with biomass raw materials not competing with food production. Several target molecules have been identified as potential fuel candidates, such as alkanes, fatty acids, long carbon‐chain alcohols and isoprenoids. The current study focuses on the biosynthesis of butanol and propane as possible biofuels. The scope of this research was to investigate novel heterologous metabolic pathways and to identify bottlenecks for alcohol and alkane generation using Escherichia coli as a model host microorganism. The first theme of the work studied the pathways generating butyraldehyde, the common denominator for butanol and propane biosynthesis. Two ways of generating butyraldehyde were described, one via the bacterial fatty acid elongation machinery and the other via partial overexpression of the acetone‐butanol‐ethanol fermentation pathway found in Clostridium acetobutylicum. The second theme of the experimental work studied the reduction of butyraldehyde to butanol catalysed by various bacterial aldehyde‐reductase enzymes, whereas the final part of the work investigated the in vivo kinetics of the cyanobacterial aldehyde deformylating oxygenase (ADO) for the generation of hydrocarbons. The results showed that the novel butanol pathway, based on fatty acid biosynthesis consisting of an acyl‐ACP thioesterase and a carboxylic acid reductase, is tolerant to oxygen, thus being an efficient alternative to the previous Clostridial pathways. It was also shown that butanol can be produced from acetyl‐CoA using acetoacetyl CoA synthase (NphT7) or acetyl‐CoA acetyltransferase (AtoB) enzymes. The study also demonstrated, for the first time, that bacterial biosynthesis of propane is possible. The efficiency of the system is clearly limited by the poor kinetic properties of the ADO enzyme, and for proper function in vivo, the catalytic machinery requires a coupled electron relay system.

Fuzzy real option analysis in patent related decision making and patent valuation

The shift towards a knowledge-based economy has inevitably prompted the evolution of patent exploitation. Nowadays, patent is more than just a prevention tool for a company to block its competitors from developing rival technologies, but lies at the very heart of its strategy for value creation and is therefore strategically exploited for economic pro t and competitive advantage. Along with the evolution of patent exploitation, the demand for reliable and systematic patent valuation has also reached an unprecedented level. However, most of the quantitative approaches in use to assess patent could arguably fall into four categories and they are based solely on the conventional discounted cash flow analysis, whose usability and reliability in the context of patent valuation are greatly limited by five practical issues: the market illiquidity, the poor data availability, discriminatory cash-flow estimations, and its incapability to account for changing risk and managerial flexibility. This dissertation attempts to overcome these impeding barriers by rationalizing the use of two techniques, namely fuzzy set theory (aiming at the first three issues) and real option analysis (aiming at the last two). It commences with an investigation into the nature of the uncertainties inherent in patent cash flow estimation and claims that two levels of uncertainties must be properly accounted for. Further investigation reveals that both levels of uncertainties fall under the categorization of subjective uncertainty, which differs from objective uncertainty originating from inherent randomness in that uncertainties labelled as subjective are highly related to the behavioural aspects of decision making and are usually witnessed whenever human judgement, evaluation or reasoning is crucial to the system under consideration and there exists a lack of complete knowledge on its variables. Having clarified their nature, the application of fuzzy set theory in modelling patent-related uncertain quantities is effortlessly justified. The application of real option analysis to patent valuation is prompted by the fact that both patent application process and the subsequent patent exploitation (or commercialization) are subject to a wide range of decisions at multiple successive stages. In other words, both patent applicants and patentees are faced with a large variety of courses of action as to how their patent applications and granted patents can be managed. Since they have the right to run their projects actively, this flexibility has value and thus must be properly accounted for. Accordingly, an explicit identification of the types of managerial flexibility inherent in patent-related decision making problems and in patent valuation, and a discussion on how they could be interpreted in terms of real options are provided in this dissertation. Additionally, the use of the proposed techniques in practical applications is demonstrated by three fuzzy real option analysis based models. In particular, the pay-of method and the extended fuzzy Black-Scholes model are employed to investigate the profitability of a patent application project for a new process for the preparation of a gypsum-fibre composite and to justify the subsequent patent commercialization decision, respectively; a fuzzy binomial model is designed to reveal the economic potential of a patent licensing opportunity.

Suomen asuntomarkkinoiden kehitys vuosina 2000-2016

Kandidaatintutkielman tarkoituksena on tutkia Suomen asuntomarkkinoiden kehitystä kuluttajamarkkinanäkökulmasta 2000-luvulta alkaen. Tutkimuksen päätavoitteena on selvittää ennalta valittujen tekijöiden avulla, kuinka nämä ovat vaikuttaneet asuntomarkkinoihin. Tekijöiden avulla pystytään selvittämään kysynnän ja tarjonnan vaikutukset asuntomyyntiin. Tutkielman teoreettisen viitekehyksen muodostavat hintakehitys ja 4C-malli. Lisäksi tutkimuksessa on selvitetty talouden heilahteluiden vaikutuksia asuntomarkkinoihin sekä rakennuslupa-asioita ja asuntotuotantoa. Aineistot koostuvat kolmesta eri haastattelusta, joita tukevat aiheeseen liittyvät tilastot ja muu kirjallisuus. Haastatteluiden analyysissä etsitään tärkeimpiä vaikuttajia asuntomarkkinoilla. Tutkimuksessa selviää kaupungistumisen aiheuttaneen suuren muuttoliikenteen kaupunkien lähettyville, minne on alkanut muodostua pienempiä kaupunkikeskuksia. Kuluttajat haluavat asunnon sijaitsevan julkisten liikenneyhteyksien ja palveluiden läheisyydessä. Asuntokoot ovat vuoden 2000 jälkeen pienentyneet, jolloin asuntotuotantoa on jouduttu sopeuttamaan. Asuntolainan koron laskun myötä asuntomyynnin kasvu ei ole ollut toivotulla tasolla. Taloudellisten heilahtelujen myötä kuluttajiin on iskenyt epävarmuus, joka vähentää ihmisten halukkuutta ostaa asuntoja.
