Non-resorbable glass fibre-reinforced composite with porous surface as bone substitute material: Experimental studies in vitro and in vivo focused on bone-implant interface

The development of load-bearing osseous implant with desired mechanical and surface properties in order to promote incorporation with bone and to eliminate risk of bone resorption and implant failure is a very challenging task. Bone formation and resoption processes depend on the mechanical environment. Certain stress/strain conditions are required to promote new bone growth and to prevent bone mass loss. Conventional metallic implants with high stiffness carry most of the load and the surrounding bone becomes virtually unloaded and inactive. Fibre-reinforced composites offer an interesting alternative to metallic implants, because their mechanical properties can be tailored to be equal to those of bone, by the careful selection of matrix polymer, type of fibres, fibre volume fraction, orientation and length. Successful load transfer at bone-implant interface requires proper fixation between the bone and implant. One promising method to promote fixation is to prepare implants with porous surface. Bone ingrowth into porous surface structure stabilises the system and improves clinical success of the implant. The experimental part of this work was focused on polymethyl methacrylate (PMMA) -based composites with dense load-bearing core and porous surface. Three-dimensionally randomly orientated chopped glass fibres were used to reinforce the composite. A method to fabricate those composites was developed by a solvent treatment technique and some characterisations concerning the functionality of the surface structure were made in vitro and in vivo. Scanning electron microscope observations revealed that the pore size and interconnective porous architecture of the surface layer of the fibre-reinforced composite (FRC) could be optimal for bone ingrowth. Microhardness measurements showed that the solvent treatment did not have an effect on the mechanical properties of the load-bearing core. A push-out test, using dental stone as a bone model material, revealed that short glass fibre-reinforced porous surface layer is strong enough to carry load. Unreacted monomers can cause the chemical necrosis of the tissue, but the levels of leachable resisidual monomers were considerably lower than those found in chemically cured fibre-reinforced dentures and in modified acrylic bone cements. Animal experiments proved that surface porous FRC implant can enhance fixation between bone and FRC. New bone ingrowth into the pores was detected and strong interlocking between bone and the implant was achieved.

Parametrització de contorns oberts

Un dels principals problemes quan es realitza un anàlisi de contorns és la gran quantitat de dades implicades en la descripció de la figura. Per resoldre aquesta problemàtica, s’aplica la parametrització que consisteix en obtenir d’un contorn unes dades representatives amb els mínims coeficients possibles, a partir dels quals es podrà reconstruir de nou sense pèrdues molt evidents d’informació. En figures de contorns tancats, la parametrització més estudiada és l’aplicació de la transformada discreta de Fourier (DFT). Aquesta s’aplica a la seqüència de valors que descriu el comportament de les coordenades x i y al llarg de tots els punts que formen el traç. A diferència, en els contorns oberts no es pot aplicar directament la DFT ja que per fer-ho es necessita que el valor de x i de y siguin iguals tan en el primer punt del contorn com en l’últim. Això és degut al fet que la DFT representa sense error senyals periòdics. Si els senyals no acaben en el mateix punt, representa que hi ha una discontinuïtat i apareixen oscil·lacions a la reconstrucció. L’objectiu d’aquest treball és parametritzar contorns oberts amb la mateixa eficiència que s’obté en la parametrització de contorns tancats. Per dur-ho a terme, s’ha dissenyat un programa que permet aplicar la DFT en contorns oberts mitjançant la modificació de les seqüencies de x i y. A més a més, també utilitzant el programari Matlab s’han desenvolupat altres aplicacions que han permès veure diferents aspectes sobre la parametrització i com es comporten els Descriptors El·líptics de Fourier (EFD). Els resultats obtinguts han demostrat que l’aplicació dissenyada permet la parametrització de contorns oberts amb compressions òptimes, fet que facilitarà l’anàlisi quantitatiu de formes en camps com l’ecologia, medicina, geografia, entre d’altres.

Treatment of oily wastewater by ultrafiltration: The effect of different operating and solution conditions

In many industries, such as petroleum production, and the petrochemical, metal, food and cosmetics industries, wastewaters containing an emulsion of oil in water are often produced. The emulsions consist of water (up to 90%), oils (mineral, animal, vegetable and synthetic), surfactants and other contaminates. In view of its toxic nature and its deleterious effects on the surrounding environment (soil, water) such wastewater needs to be treated before release into natural water ways. Membrane-based processes have successfully been applied in industrial applications and are considered as possible candidates for the treatment of oily wastewaters. Easy operation, lower cost, and in some cases, the ability to reduce contaminants below existing pollution limits are the main advantages of these systems. The main drawback of membranes is flux decline due tofouling and concentration polarisation. The complexity of oil-containing systems demands complementary studies on issues related to the mitigation of fouling and concentration polarisation in membranebased ultrafiltration. In this thesis the effect of different operating conditions (factors) on ultrafiltration of oily water is studied. Important factors are normally correlated and, therefore, their effect should be studied simultaneously. This work uses a novel approach to study different operating conditions, like pressure, flow velocity, and temperature, and solution properties, like oil concentration (cutting oil, diesel, kerosene), pH, and salt concentration (CaCl2 and NaCl)) in the ultrafiltration of oily water, simultaneously and in a systematic way using an experimental design approach. A hypothesis is developed to describe the interaction between the oil drops, salt and the membrane surface. The optimum conditions for ultrafiltration and the contribution of each factor in the ultrafiltration of oily water are evaluated. It is found that the effect on permeate flux of the various factors studied strongly depended on the type of oil, the type of membrane and the amount of salts. The thesis demonstrates that a system containing oil is very complex, and that fouling and flux decline can be observed even at very low pressures. This means that only the weak form of the critical flux exists for such systems. The cleaning of the fouled membranes and the influence of different parameters (flow velocity, temperature, time, pressure, and chemical concentration (SDS, NaOH)) were evaluated in this study. It was observed that fouling, and consequently cleaning, behaved differently for the studied membranes. Of the membranes studied, the membrane with the lowest propensity for fouling and the most easily cleaned was the regenerated cellulose membrane (C100H). In order to get more information about the interaction between the membrane and the components of the emulsion, a streaming potential study was performed on the membrane. The experiments were carried out at different pH and oil concentration. It was seen that oily water changed the surface charge of the membrane significantly. The surface charge and the streaming potential during different stages of filtration were measured and analysed being a new method for fouling of oil in this thesis. The surface charge varied in different stages of filtration. It was found that the surface charge of a cleaned membrane was not the same as initially; however, the permeability was equal to that of a virgin membrane. The effect of filtration mode was studied by performing the filtration in both cross-flow and deadend mode. The effect of salt on performance was considered in both studies. It was found that salt decreased the permeate flux even at low concentration. To test the effect of hydrophilicity change, the commercial membranes used in this thesis were modified by grafting (PNIPAAm) on their surfaces. A new technique (corona treatment) was used for this modification. The effect of modification on permeate flux and retention was evaluated. The modified membranes changed their pore size around 33oC resulting in different retention and permeability. The obtained results in this thesis can be applied to optimise the operation of a membrane plant under normal or shock conditions or to modify the process such that it becomes more efficient or effective.

Saako historiasta selvää? Monikulttuuriset yläkoululaiset historian lähteillä historian taidot motiivien, seurauksien, historian tulkintojen ja lähteiden luotettavuuden arvioinneissa

The research assesses the skills of upper comprehensive school pupils in history. The focus is on locating personal motives, assessing wider reasons hidden in historical sources and evaluating source reliability. The research also questions how a wide use of multiple sources affects pupils’ holistic understanding of historical phenomena. The participants were a multicultural group of pupils. The origins of their cultures can be traced to the Balkan, the Middle East, Asia and Europe. The number of native Finnish speakers and pupils speaking Finnish as their second language was almost equal. The multicultural composition provides opportunities to assess how culturally responsive learning history from sources is. The intercultural approach to learning in a multicultural setting emphasizes equality as a precondition for learning. In order to set assignments at least to some extent match with all participants only those answers were taken into account which were produced by pupils who had studied history for a similar period of time in the Finnish comprehensive school system. Due to the small number of participants (41), the study avoids wide generalizations. Nevertheless, possible cultural blueprints in pupils’ way of thinking are noted. The first test examined the skills of pupils to find motives for emigration. The results showed that for 7th graders finding reasons is not a problematic task. However, the number of reasons noticed and justifications varied. In addition, the way the pupils explained their choices was a distinguishing factor. Some pupils interpreted source material making use of previous knowledge on the issue, while other pupils based their analysis solely on the text handed and did not try to add their own knowledge. Answers were divided into three categories: historical, explanatory and stating. Historical answers combined smoothly previously learned historical knowledge to one’s own source analysis; explanatory answers often ignored a wider frame, although they were effective when explaining e.g. historical concepts. The stating answers only noticed motives from the sources and made no attempts to explain them historically. Was the first test culturally responsive? All pupils representing different cultures tackled the first source exam successfully, but there were some signs of how historical concepts are understood in a slightly different way if the pupil’s personal history has no linkage to the concepts under scrutiny. The second test focused on the history of Native Americans. The test first required pupils to recognize whether short source extracts (5) were written by Indians or Caucasians. Based on what they had already learned from North American history, the pupils did not find it hard to distinguish between the sources. The analysis of multiphase causes and consequences of the disputes between Native Americans and white Americans caused dispersion among pupils. Using two historical sources and combining historical knowledge from both of them simultaneously was cumbersome for many. The explanations of consequences can be divided into two groups: the ones emphasizing short term consequences and those placing emphasis on long term consequences. The short term approach was mainly followed by boys in every group. The girls mainly paid attention to long term consequences. The result suggests that historical knowledge in sources is at least to some extent read through role and gender lenses. The third test required pupils to explain in their own words how the three sources given differed in their account of living conditions in Nazi Germany, which turned out to be demanding for many pupils. The pupils’ stronghold was rather the assessment of source reliability and accounts why the sources approached the same events differently. All participants wrote critical and justified comments on reliability and aspects that might have affected the content of the sources. The pupils felt that the main reasons that affected source reliability were the authors’ ethnic background, nationality and profession. The assessment showed that pupils were well aware that position in a historical situation has an impact on historical accounts, but in certain cases the victim’s account was seen as a historical truth. The account of events by a historian was chosen most often as the most reliable source, but it was often justified leniently with an indication to professionalism rather than with clear ideas of how historians conduct accounts based on sources. In brief, the last source test demonstrates that pupils have a strong idea that the ethnicity or nationalism determines how people explained events of the past. It is also an implication that pupils understand how historical knowledge is interpretative. The results also imply that history can be analyzed from a neutral perspective. One’s own membership in an ethnical or religious group does not automatically mean that a person’s cultural identity excludes historical explanations if something in them contradicts with his or her identity. The second method of extracting knowledge of pupils’ historical thinking was an essay analysis. The analysis shows that an analytical account of complicated political issues, which often include a great number of complicated political concepts, leads more likely to an inconsistent structure in the written work of pupils. The material also demonstrates that pupils have a strong tendency to take a critical stance when assessing history. Historical empathy in particular is shown if history somehow has a linkage to young people, children or minorities. Some topics can also awake strong feelings, especially among pupils with emigrant background, if there is a linkage between one’s own personal history and that of the school; and occasionally a student’s historical experience or thoughts replaced school history. Using sources during history lessons at school seems to have many advantages. It enhances the reasoning skills of pupils and their skills to assess the nature of historical knowledge. Thus one of the main aims and a great benefit of source work is to encourage pupils to express their own ideas and opinions. To conclude, when assessing the skills of adolescents in history - their work with sources, comments on history, historical knowledge and finally their historical thinking - one should be cautious and avoid cut off score evaluations. One purpose of pursuing history with sources is to encourage pupils to think independently, which is a useful tool for further identity construction. The idea that pupils have the right to conduct their own interpretations of history can be partially understood as part of a wider learning process, justification to study history comes from extrinsic reasons. The intrinsic reason is history itself; in order to understand history one should have a basic understanding of history as a specific domain of knowledge. Using sources does not mean that knowing history is of secondary importance. Only a balance between knowing the contextual history, understanding basic key concepts and working with sources is a solid base to improve pupils’ historical understanding.

Acilação de Friedel-Crafts do 2-metoxinaftaleno usando o ácido dodecafosfotúngstico suportado em sílica (HPW/SiO2) como catalisador e acetonitrila como solvente

The synthesis of fine chemicals intermediates using Friedel-Crafts acylation is one of the most important methods in chemical technology. In this work, the acylation of 2-methoxynaphthalene with acetic anhydride using a silica-supported dodecatungstophosphoric acid catalyst (HPW/SiO2) and acetonitrila as solvent was studied, showing that this reaction is a feasible alternative to produce intermediaries to replace the current methods of production. The reactions using acetonitrile solvent showed yields greater than or equal to the reactions using traditional solvents such as nitrobenzene and dichloroethane. Finally, the modified Eley-Rideal mechanism was proposed to elucidate the experimental data obtained.

Aplicação de fotólise direta e UV/H2O2 a efluente sintético contendo diferentes corantes alimentícios

Food industries employ a lot of synthetic dyes in their products. Most of these dyes are very stable face to the conventional treatments. This work studied the use of advanced oxidation process (AOP) as an alternative to the conventional ones to degrade a synthetic food effluent (photolysis and UV/H2O2 in continuous reactor). The more efficient process was the UV/H2O2 and it presented decoloration and degradation energetic efficiency values equal to 30.775 kWh m-3 and 269.909 kWh m-3, respectively. The color reduction was 96.4% and COD decrease was 38.56%.

Síntese hidrotermal assistida por micro-ondas como metodologia sintética eficiente para obtenção da rede metalorgânica [ZN(BDC)(H2O)2]n

This work presents the optimization of the microwave-assisted hydrothermal synthesis of [Zn(BDC)(H2O)2]n . The reactions were carried out at the fixed temperature of 120 ºC for 10, 20, 30 and 40 min. Pure crystalline [Zn(BDC)(H2O)2]n was obtained in high yield (ca. 90%) with a reaction time of 10 min. The phase obtained and its purity was confirmed by Rietveld refinement, with a final value for Rwp/Rexp equal to 1.48. Increased reaction times (20, 30 and 40 min) favored the formation of unwanted by products, resulting in mixtures of several crystalline phases.

Parametric sensitivity analysis for the helium dimers on a model potential

Potential parameters sensitivity analysis for helium unlike molecules, HeNe, HeAr, HeKr and HeXe is the subject of this work. Number of bound states these rare gas dimers can support, for different angular momentum, will be presented and discussed. The variable phase method, together with the Levinson's theorem, is used to explore the quantum scattering process at very low collision energy using the Tang and Toennies potential. These diatomic dimers can support a bound state even for relative angular momentum equal to five, as in HeXe. Vibrational excited states, with zero angular momentum, are also possible for HeKr and HeXe. Results from sensitive analysis will give acceptable order of magnitude on potentials parameters.

OTIMIZAÇÃO DO PROCESSO DE TRANSESTERIFICAÇÃO EM DUAS ETAPAS PARA PRODUÇÃO DE BIODIESEL ATRAVÉS DO PLANEJAMENTO EXPERIMENTAL DOEHLERT

In this work, Doehlert experimental design was used to optimize the Transesterification Double Step Process (TDSP) method of methyl soybean oil biodiesel production which starts with a basic catalysis followed by an acidic catalysis. The conversion values were calculated from NMR spectra. Response surface was used to show the results of the interactions between the variables. This experimental design evaluated variables like catalyst and alcohol amount for the basic catalysis and time and temperature for the acidic catalysis. According to results obtained after Doehlert design application the alcohol amount was the main factor that influenced on the basic catalysis but for the acidic catalysis both time and temperature are important and their effects are opposite. It resulted on excellent conversions for both steps obtaining for the basic catalysis about 100% when was used like optimal conditions catalyst amount equal to 0.40 g and volume of methanol equal to 60 mL and for the acidic catalysis about 99% when was used like optimal conditions temperature of 65 °C and 90 minutes for reaction time.

Ultralujasta teräksestä valmistetun liitoksen pienahitsin staattinen kestävyys

Ultralujat teräkset ovat teräksiä, joiden lujuus on reilusti suurempi verrattuna perinteisiin rakenneteräksiin. Niiden ominaisuuksia hyödynnetään eniten nosto- ja kuljetusvälinete¬ollisuudessa. Ultralujien terästen käyttö avaa suunnittelijalle uusia mahdollisuuksia suun¬nitella ulottuvampia ja kevyempiä rakenteita, jolloin voidaan saavuttaa säästöjä niin val¬mistus- kuin polttoainekustannuksissakin. Ultralujille teräksille ei kuitenkaan ole ole¬massa niitä vastaavia suunnitteluohjeita tai standardeja. Teräsrakenteiden liitosten suun¬nitteluun mitoitusohjeita antava standardi SFS-EN 1993-1-8 ei huomioi teräksiä, joiden myötölujuus on yli 460 MPa. SFS-EN 1993-1-12 on 1993-1-8:n laajennus, joka on voi¬massa myötölujuuteen 700 MPa asti. Tässä diplomityössä tutkittiin ultralujista teräksistä valmistettujen pienahitsiliitosten käyttäytymistä vetokokeiden ja elementtimenetelmän avulla. Tulosten avulla voitiin mää¬rittää matalalujuuksisten terästen mitoitusohjeiden soveltuvuutta ultralujille teräksille. Kokeissa käytetty teräs oli Ruukin valmistama Optim 960 QC.

Taselaskentajärjestelmän kehittäminen pohjoismaisille sähkömarkkinoille

Pohjoismaisia sähkömarkkinoita ollaan avaamassa myös vähittäismarkkinoiden osalta. Jotta vähittäismarkkinoista saataisiin toimiva, kaikille avoin ja tasapuolinen kauppapaikka, on markkinamenetelmiä yhtenäistettävä. Yhtenäistäminen tarkoittaa muutoksia ennen kaikkea taseselvityksessä ja viestiformaateissa. Tämä tarkoittaa lisätyötä eri markkinaosapuolille ja heidän järjestelmätoimittajilleen. Tässä työssä tutkittiin näköpiirissä olevien muutosten vaikutuksia järjestelmätoimittajan valmiiseen jakeluverkonhaltijoille suunnattuun tietojärjestelmätuotteeseen. Tavoitteena oli selvittää, mitä muutoksia markkinoille on tulossa lähivuosina, tutkia mitkä niiden tuomat vaatimukset ovat tuotteelle ja minkälaisia muutoksia tuotteeseen nämä markkinamuutokset aiheuttavat. Tutkimuksen pohjalta pystyttiin arvioimaan vaadittavat toimenpiteet ja markkinoilla tapahtuvien muutosten vakavuus kohteena olevalle tietojärjestelmälle. Tutkimuksen sivutuotteena havaittiin myös muita kehityskohteita, jotka toisivat tuotteelle lisäarvoa.

Hallinnollinen sanktiointi

Tausta Suomessa lainsäätäjä reagoi helposti yhteiskunnalliseen häiriötekijään rikosoikeuden keinoin. Tästä on osoituksena se, että syksyllä 2010 varsinaisen rikoslain lisäksi rikoksesta oli säädetty 256 eri laissa. Suomalainen, lähtökohdiltaan maltillinen kontrolli- ja kriminaalipolitiikka on 1970-luvulla linjatun vastaisesti johtanut 2000-luvulle tultaessa rikosoikeudellisen kontrollin lisääntymiseen ja jopa kiristymiseen. Raja rikosten ja rikkomusten välillä on liudentunut ja paikoitellen kadonnut ja erityisesti turvallisuudesta on kehittynyt – käsitteeseen liittyvistä oikeudellisista jännitteistä huolimatta – keskeinen rikosoikeudellisen sääntelyn oikeutusperuste. Rikosoikeuden käyttäminen vähäisten rikosten kontrollointiin on aiheuttanut Suomeen viivästymisen ongelman. Yleisessä tiedossa on se, että Euroopan ihmisoikeustuomioistuin on antanut 2000-luvulla Suomelle kymmeniä tuomioita siksi, että rikosjuttuja on käsitelty viranomaisissa ja tuomioistuimissa liian kauan. Vähemmän on sen sijaan keskusteltu siitä, että myös vähäiset rikokset viivästyvät rikosoikeuden alan laajetessa ja viranomaisten voimavarojen ehtyessä. Suomessa ongelmaa on pyritty hoitamaan rikosoikeudellista toimivaltaa hallintoviranomaisille delegoimalla tilanteen ollessa nyt se, että uuden sakkomenettelylain voimaan tullessa noin 90 % rikosoikeudellisesta kompetenssista on poliisilla ja muilla hallintoviranomaisilla. Se taasen on ongelmallista perustuslain 3 §:ssä säädetyn vallanjakoperiaatteen kannalta. Välttämätöntä on korostaa myös sitä, että pääosin rikosoikeudelliseen kontrolliin perustuva systeemi aiheuttaa rikosoikeuden inflaatiota: rikosoikeuden arvostuksen vähenemisestä aiheutuvia ei-mittavissa olevia kuluja. Rikosoikeuden laajenemista vastaan esitetään kuitenkin harvoin kritiikkiä. Rikosoikeustieteen piirissäkään sille ei ole esitetty vakavasti otettavaa vaihtoehtoa. Esimerkiksi hallinnollisia sanktioita ei ole Suomessa – ei tosin muissa Pohjoismaissakaan – koettu rikosoikeuden vaihtoehtona, vaan usein rikosoikeutta täydentävänä järjestelmänä. Hallinnollisten sanktioiden käyttäminen rikosoikeuden ohessa ei ole ollut yksiselitteistä ja jäsenneltyä, yleisiin oppeihin perustuvaa. Kontrollin erityisille alueille, esimerkiksi sotilaskontrolliin, on lisäksi kehittynyt rikos- ja hallinto-oikeuden sekajärjestelmiä. Tutkimuskysymykset Käsillä olevassa artikkelimuotoisessa väitöskirjatutkimuksessa pyritään hahmottelemaan rikos- ja hallinto-oikeudellisten rangaistusjärjestelmien välisiä eroavaisuuksia Suomessa. Tutkimuksen keskeisin tehtävä on sen pohtiminen, millä tavalla 2010-luvulle tultaessa olisi tutkimuksen empiiriset ja teoreettiset lähtökohdat huomioon ottaen järkevää ja tarkoituksenmukaista rangaista. Tällä perusteella kehitetään yksikertaista hallintosanktiointiteoreettista mallia, että sitä hyväksikäyttäen lainvalmisteluprosessin sanktiointitilanteessa, sanktiosta päätettäessä, olisi mahdollista asettaa oikeusturvan vähimmäistakeet täyttävällä tavalla oikeus- ja muilta vaikutuksiltaan rationaalinen seuraamus sekä säätää sen määräämiseksi yhteiskunnallisilta vaikutuksiltaan tehokas ja riittävän oikeusturvallinen menettely. Tutkimustehtävä on tiivistetysti 1) hallinnollisten sanktioiden ja rikosoikeudellisten rangaistusten ja niiden alan määrittäminen, 2) hallinnollisten sanktioiden sääntelymallien valintaperusteluiden selvittäminen, 3) hallintosanktioteoreettisen mallin kehittäminen lainvalmisteluprosessia varten sekä 4) de lege ferenda -suositusten tekeminen rangaistavuuden hyväksyttävyyden ja joutuisuuden parantamiseksi. Menetelmä ja aineistot Tutkimus kytkeytyy teoreettisen rikosoikeustieteen, hallinto-oikeustieteen ja prosessioikeustieteen alalle ja se on luonteeltaan ongelmakeskeinen. Tieteenalojen väliset painotukset ja niiden vaikutus vaihtelevat tutkimuksessa. Vaikka tutkimus on monella tavalla luonteeltaan teoreettinen, siinä rakennetaan nimenomaan lainsäädäntötyötä ja lainvalmistelua tukevaa tutkimusta ja teoriaa. Tältä osin näkökulma liittyy kriminalisointiteoreettisessa tutkimuksessa hahmotettuun lainsäätäjän oikeuslähdeoppia koskevaan uuteen näkökulmaan, jolla on yhteyksiä lainsäädäntötutkimukseen ja oikeusteoriassa hahmotettuun legisprudence-tutkimusuuntaukseen, näkökulman suuntautuessa lainsäädäntötasolle. Tutkimuksen lähteistä suurin osa on oikeustieteellistä kirjallisuutta, jonka pääosa muotoutuu suomalaisesta oikeustieteellisestä kirjallisuudesta. Myös pohjoismaalaista, saksalaista ja hieman myös anglosaksista kirjallisuutta on käytetty. Kansainvälisten kirjallisuuslähteiden merkitys ei ole ollut merkittävä, koska kattava eurooppalainen näkemys aihepiiristä on pyritty saamaan Euroopan ihmisoikeustuomioistuimen ratkaisukäytäntöä hyödyntäen. Tutkimuksen lähteinä on käytetty laajasti myös kansallista lainvalmisteluaineistoa, erityisesti hallituksen esityksiä ja perustuslakivaliokunnan lausuntokäytäntöä. Johtopäätökset Kriminaali- ja/tai kontrollipolitiikassa on juuri nyt tärkeää pohtia, millä tavalla 2010-luvulle tultaessa on järkevää ja tarkoituksenmukaista rangaista. Tähän voisi olla mahdollista vastata tutkimuksessa kehitettävällä hallintosanktiointiteoreettisella mallilla. Mallin kehittäminen on edellyttänyt yhteiskunnallisten sanktiokäytäntöjen oikeusvaltioopillista tarkastelua, jolloin sanktioiden yhteiskunnalliseen merkitykseen pureutuminen kuvailee myös sitä, millainen modernin oikeusvaltion tila tällä hetkellä on. Perinteisten oikeusvaltioiden paradigmojen käyttäminen ei välttämättä edistä relevantin oikeusvaltiollisen sanktiointiteoreettisen mallin kehittämistä. Voi olla niinkin, että klassinen oikeusvaltio-oppi ja oletetunlaiset rikosoikeuden erityiset elementit eivät enää vastaa yhteiskuntatodellisuutta. Näin rankaisemisen yleiset opit voivat nousta kehittämisen kohteeksi oikeusvaltiollisuuden elementtien toteuttamiseksi valtavasta kasvaneessa hallintoyhteiskunnassa – hallinto-johtoisessa yhteiskunnallisessa todellisuudessa. Suomen rikoslaki sisältää laajassa merkityksessä sadoittain erilaatuisia kriminalisointeja, joiden merkitys on usein hallinnon toimintaa subventoiva, symbolinen tai jonkin toisen kriminalisoinnin vaikutusta tehostamaan pyrkivä. Tällainen rikoslaki on tehtävänsä, vaikuttavuutensa ja hyväksyttävyytensä kannalta ongelmallinen. Suomalainen hallinnollisten sanktioiden järjestelmä ei sekään ole järkevä ja tarkoituksenmukainen, yleisiin oppeihin perustuva systeemi. Myös yleiseurooppalainen kehitys näyttäisi viittaavan siihen, että Suomessa on tarve kehittää sekä rikosoikeutta että sille vaihtoehtoista hallintosanktioiden järjestelmää, sanktio-oikeutta. Tämä edellyttää lainsäädäntöuudistuksia.

Diameter structure of stratum and ecological groups of a Semideciduous Forest area in Dionísio-MG

The objective of this study was to obtain homogeneous groups of species and information on their density, dominance and volume, in terms of ecological group and diameter structure of an area of Submontane Semideciduous forest (Mata do Mumbaça) in Dionísio, MG. This work was conducted with data of the diameter distribution per species from floristic and phytosociological (Mata do Mumbaça) survey of 120 plots with 10 x 10 m each one. The 120 plots were contiguous and corresponding to a total sample area of 12,000 m² distributed over the topographic units (Low Ramp, Lower Slope, Upper Slope and Hill Top). The topographic units Low Ramp, Lower Slope and Upper Slope were in the middle stage of succession as they presented incipient stratification into two strata (canopy and understory) i.e. canopy ranging from 5 to 12 m high. However, the stratum Hill Top was classified as intermediate/advanced succession because it had a total height equal to or greater than 12 m. The distribution of individual trees of the four strata on diameter classes showed a typical J-inverted pattern that is, high concentration of individuals in smaller diameter classes and a sharp reduction towards the larger classes. In relation to absolute dominance and total volume of species, the ecological group that stood out in the four strata (Low Ramp, Lower Slope, Upper Slope and Hill Top) was the initial secondary, which were in the intermediate stage of secondary, rapidly developing into the mature phase.

Perspektivmöten i skola och handledning : lärares tankar om specialpedagogisk handledning

To create a more inclusive school, an increase in multidisciplinary cooperation is needed. One possible form of collaboration could encompass the special education teacher taking on the role of a consultant for other teachers in need of support in working with heterogeneous groups of pupils. Previous research shows that special education teachers see the role as consultant as diffuse and complex. The overarching aim of the present study involves deepening the knowledge on how consultation in a special educational context can be understood and developed based on teachers’ descriptions on this particular form of activity interpreted against various perspectives on consultation. The study is qualitative in nature and rests on a hermeneutic interpretive research tradition in combination with an abductive approach. The theoretical framework consists of two different approaches to consultation: the directive and the non-directive approach. The approaches differ regarding particular emphasis on advice and reflection during the consultation and with respect to who or what should be the focus of the consultation. The two approaches are here studied through various theories such as social learning theory, Bruner's theory of scaffolding, Roger’s humanist psychology, and constructivism. Semi-structured interviews were held with eighteen special education teachers (n=9) and class teachers (n=9) working in the compulsory school. The overall interpretation of the results shows that special education consultation can be understood as three different types of consultation. Consultation as counseling which harmonizes with the directive perspective on consultation is the most prominent type. In the consultation as counseling conversation, the special educational knowledge transfer is central and the focus is placed on the pupil. Although special education knowledge transfer emerges as a unique aspect of special education consultation, there are several inherent challenges in this type of consultation that can be addressed in that teachers also describe two other types of consultation. In the reflective consultation, there is a move away from the pupil focus and toward a focus on the class teacher and the use of reflection. The reflective consultation harmonizes with the non-directive approach to consultation. This type of consultation does not as of yet have a prominent place in the Finland-Swedish school context and at this stage it is not seen as a legitimate type of consultation according to the teachers’ descriptions. Despite this, certain aspects of the reflective conversation could be given more space in the development of consultation within special educational contexts. The co-operative consultation is characterized by the teachers acting as teammates and using professional exchange as a strategy for consultation. Both teachers' knowledge is seen as central, and rather than the special education teacher acting as the expert and moderator, the teachers control the consultation together and jointly move the work along. The co-operative consultation enables the focus to move from the pupil toward the context, which can lead to the development of inclusive practices. The results indicate that this type of consultation holds potential in the development of special educational consultation that takes place between equal colleagues. The co-operative consultation opens up for a third collaborative approach to consultation, where aspects of the directive and non-directive perspective can merge and develop. The thesis concludes with the proposal that special pedagogical consultation can be understood from an integrated perspective. The characteristics of the consultation can vary depending on the type of problem or situation, while co-operative consultation can be seen as the ideal as equal colleagues meet in consultation conversations. In order to develop the co-operative consultation, both teachers are required to have knowledge of consultation as a practice, to be part of a collaborative school climate, and that teachers are provided with enough time to take part in consultations.
