Tämän tutkielman tavoitteena oli perehtyä niihin eri tekijöihin, jotka muokkaavat lapsille suunnattujen mainosten ulkoasua ja sisältöä. Lapsella tässä tutkimuksessa tarkoitetaan alle 12-vuotiasta lasta, tutkimuksen pääpaino oli kuitenkin alle kouluikäisissä, 3-6 -vuotiaissa lapsissa. Tutkimuksen tutkimusmetodologia on kvalitatiivinen haastattelututkimus. Tutkimusta varten haastateltiin 16 alle kouluikäistä lasta, yhdeksää tyttöä ja seitsemää poikaa. Lapsille suunnattujen mainosten sisältöön ja ulkoasuun vaikuttavat muiden muassa. seuraavat tekijät: 1. ulkoinen säätely (lait, asetukset, kuluttaja-asiamiehen ohjeet, EU-direktiivit), 2. sisäinen säätely (mainostajien alan oma eettinen ohjeistus), 3. lapsen ikä ja kehitysaste sekä 4. lapsen mielipiteet. Suunniteltaessa lapsille suunnattua mainontaa, ulkoisen ja sisäisen säätelyn antamien ohjenuorien lisäksi on mainosviestin ymmärtämisen kannalta tärkeää huomioida lapsen kognitiivinen kehitysaste ja sen vaikutus lapsen kykyyn ymmärtää mainoksia. Lapsen mielipiteeseen siitä, millainen on hyvä mainos ja millaisista mainoksista hän ei pidä vaikuttaa iän lisäksi hyvin vahvasti lapsen sukupuoli.

Työn tavoitteena oli selvittää mitä erityspiirteitä esiintyy siirryttäessä kompetenssipohjaiseen organisaatiorakenteeseen ja toimintaan sekä kuvata muutoksen toteutusprosessi. Tutkimus pitää sisällään kaksi keskeisintä ja tärkeää käsitettä: osaamisrakenteen muutos ja sen johtaminen. Empiirinen osa on toteutettu kyselylomakkeen avulla, joka lähetettiin valituille Case-yrityksen operatiivisesta johtamisesta vastuussa oleville esimiehille. Organisaation muutoksen toteuttaminen on erittäin vaativa toimenpide, joka vaikuttaa organisaation jokaiseen henkilöön ja heidän päivittäisiin työtehtäviinsä. Muutoksen toteuttaminen vaatii paljon aikaa, mutta ennen kaikkea kärsivällisyyttä. Mitä isommasta organisaatiosta on kysymys, sitä vaikeampaa toteuttaminen on. Muutokseen vaikuttavat oman henkilöstön lisäksi organisaation ulkoiset tekijät, kuten asiakkaat, markkinat sekä erilaiset osaamiseen ja teknologiaan liittyvät uudenlaiset osaamisvaatimukset. Tärkein tekijä muutoksen onnistumisen kannalta on tiedostaa koko organisaation tasolla, miksi muutokseen lähdetään ja mitkä ovat muutoksen tavoitteet. Tavoitellaanko muutoksella pientä hienosäätöä organisaation toiminnassa vai onko taustalla kokonaan uuden toimintamallin käyttöönotto uudenlaisia strategisia linjauksia myöten.

Global population aging over recent years has been linked to poorer health outcomes and higher healthcare expenditure. Policies focusing on healthy aging are currently being developed but a complete understanding of health determinants is needed to guide these efforts. The built environment and other external factors have been added to the International Classification of Functioning as important determinants of health and disability. Although the relationship between the built environment and health has been widely examined in working age adults, research focusing on elderly people is relatively recent. In this review, we provide a comprehensive synthesis of the evidence on the built environment and health in the elderly.

Collaboration between competing firms (coopetition) has emerged as an important issue forn business practice in many industries. Extant literature has examined coopetition on many levels of analysis, but lacks clarity in distinguishing it explicitly from cooperation between noncompeting organizations. Because of this, the performance implications of coopetition from the perspective of an individual firm are still ambiguous – some research suggests positive results whereas other studies suggest detrimental outcomes. The aim in this dissertation is to narrow these gaps by exploring how firms create and appropriate value through collaboration with their competitors. The dissertation is divided into two parts. The first part comprises an overview of the relevant literature, as well as the conclusions of the whole study, and the second part includes six research publications. Both qualitative and quantitative methodologies are utilized. The results suggest that coopetition embodies the distinctive logic of value creation and appropriation from the perspective of an individual firm, and thus differs in terms of performance implications from cooperation between non-competitors. The distinction comes from the fact that competitors have somewhat similar understanding, capabilities and interest related to certain markets, which is potentially both challenging and beneficial in terms of the individual firm’s competitiveness. It appears from the findings that there are distinctive firm-external and firm-specific factors affecting the success of a coopetition strategy. This study makes three main contributions. First, on the conceptual level it shows the distinction between coopetition and cooperation between non-rivals as a collaborative inter-organizational relationship. Secondly, it sets out a framework and propositions that enhance understanding of how value is created and appropriated in coopetition from the perspective of an individual firm. Thirdly, it offers empirical evidence of how coopetition affects firms’ innovation and market performance, and identifies the focal internal and external factors involved. In general terms, the thesis adds to our knowledge of how a firm can successfully utilize a coopetition strategy in its pursuit of improved performance.

Electrical motors on a ship attackable to different factors which decrease these lifetimes. One of the main external factors on a ship which usually is a reason of the motor failure is a moisture condensation which decreases the motor winding insulation and increase a probability of the short circuit. Therefore, the protection against moisture is necessary for ship electrical motors. The motor should be protected against moisture all time when it does not operate. The necessity of such protection requires a lot of energy consumption. This master’s thesis is focused on the creation of the electrical motor thermal model and on the different methods of the motor protection against moisture analysis with energy consumption point of view.

The resources of the step family and the children’s well-being The present study investigates children's well-being in stepfamilies and fac¬tors, both external and internal, that are related to the children's well-being. Of the external factors, the study focuses on factors related to the structure of the stepfamily, parents' education, socio-economic status and factors related to work, livelihood and living conditions. The internal resources include the general functioning of the family, parenthood and parenting, family support networks and issues that the stepfamilies themselves consider important. Another important resource in a stepfamily is a functioning network of human relationships, which in the present study is approached from the maternal viewpoint. Changing family relations are considered a potential threat to the children's well-being. Therefore, in addition to looking into the stepfamily's resources, the other important goal of the study is to explore other factors potentially related to the well-being of children living in stepfamilies. In view of the stepfamily's resources, it is important to explore how the functioning of the relationships network is linked with the child's well-being. The study employs survey and interview data. The survey data (n=2236) are part of national survey data on the well-being of families and children and factors impacting them which were gathered as part of ”Origins of Exclusion in Early Childhood”, a research project carried out in 2002. The data consists of 667 stepfamilies. The interview data consists of interviews with 24 parents in stepfamilies. In the study, the analyses of survey and interview data are combined. Both descriptive statistical analyses and multivariate methods are employed. Content analysis is employed in the analysis of the interview data. The results indicate that the stepfamilies’ resources in general but their external resources in particular differed from those of the nuclear and single-parent families. The level of education and the socio-economic status of the stepfamily parents were somewhat lower than those of the nuclear family parents. The differences in relation to single-parent families were primarily related to the better economic status of the stepfamilies. The analysis of internal resources showed relatively minor differences: the stepfamilies assessed themselves a somewhat better general functioning of the family than did the nuclear families. Parenting issues caused more disagreement in stepfamilies than in nuclear families. The analysis of the functioning of the human relations in stepfamilies showed that the stepfamily mothers experienced the external relationships of the family (e.g., between the child and the absent father) as significantly more problematic than the relationships within the stepfamily. Living in a stepfamily thus challenges the functioning of the relationship between the child and the absent father. As a result of the analysis of the relationships networks in the stepfamilies, three groups were formed. One group had the nuclear family as an ideal goal, another valued an extended family composed of a variety of relationships, and the third one appreciated a strong intimate relationship between the parents. In the present study, the most common group was the multi-relationship, extended type of stepfamily. In conclusion, living in a stepfamily does not seem to pose a risk to the child’s well-being, but it may influence the family’s resources and thus have an indirect effect on the child’s well-being. In view of the resources of the stepfamily, the child’s well-being was best supported by a functioning network of human relationships in the stepfamily: there was a distinct connection with the children’s problems and the non-functioning of the relationships network. According to the mothers, the internal relationships in the stepfamily seemed to be more important than the external relationships of the family. A child’s functioning relationship with the absent father can be viewed as a positive resource, supporting the child’s well-being in the stepfamily.

Diplomityössä tarkastellaan liikennemuotojen yhteiskunnalle kohdistamia kustannuksia, jotka syntyvät ylläpidosta, investoinneista sekä ulkoisista tekijöistä. Liikenteen hinnoittelussa ei useinkaan huomioida ulkoisia kustannuksia kuten päästöjen, melun sekä onnettomuuksien aiheuttamia kustannuksia, joiden laskentaan ja muodostumiseen tässä diplomityössä kiinnitetään erityisesti huomiota. Työn teoriaosassa selvitetään taustaa liikenteen hinnoittelulle sekä esitetään Suomessa käytössä oleva malli liikenteestä muodostuvien kokonaiskustannuksien huomioimiseksi. Tämän lisäksi vertaillaan ulkoisten kustannuksien laskentaa Suomen ja Euroopan välillä. Empiriaosassa lasketaan yhteiskunnalle kohdistuvat kustannukset kahdessa case esimerkissä. Suomessa liikenteen aiheuttamat kustannukset huomioidaan osana hankearviointeja. Näissä ulkoisten kustannuksien osuus on vähäinen muihin kustannuksiin verrattuna. Kirjallisuusselvityksen sekä empiria osuuden perusteella Suomessa tarvitaan lisäselvitystä ulkoisista kustannuksista, jos halutaan saada niiden arvo vastaamaan paremmin Suomen olosuhteita. Investointi ja ylläpitokustannukset on kohdennettu vain tieliikenteessä ajoneuvosuoritetta kohden. Vastaavaa tietoa ei ole saatavissa muiden tarkasteltujen kuljetusmuotojen osalta.

When doing researches on solute dynamics in porous medium, the knowledge of medium characteristics and percolating liquids, as well as of external factors is very important. An important external factor is temperature and, in this sense, our purpose was determining potassium and nitrate transport parameters for different values of temperature, in miscible displacement experiments. Evaluated parameters were retardation factor (R), diffusion/dispersion coefficient (D) and dispersivity, at ambient temperature (25 up to 28 ºC), 40 ºC and 50 ºC. Salts used were potassium nitrate and potassium chlorate, prepared in a solution made up of 5 ppm nitrate and 2.000 ppm potassium, with Red-Yellow Latosol porous medium. Temperature exhibited a positive influence upon porous medium solution and upon dispersion coefficient.

The Lutheran Church of El Salvador made a decision, in 1986, to open the ministry to women. How was it possible in the midst of a Latin American macho culture and after having been influenced by the theologically conservative, North American mission work? This research examines the kinds of internal and external factors which led women to leadership and ministry, and the context in which this development occurred. The roles of women have been scrutinised during several time periods. During 1952-1974 the focus was on women as missionary wives and fundadoras (founding mothers). Women’s roles as laywomen grew in 1975-1985. After the outburst of the civil war in 1980, women advanced to lay leaders. The ministry was opened for women and the first deacon pastors were installed in 1986 and the first presbyter pastors were ordained in 1994. In 2009, more women than ever were working in different levels – from laywomen to leaders – in the Lutheran Church of El Salvador. The research shows that the reasons for the development and changes concerning women’s positions and roles lie in the impact of significant individuals, liberation theology, the feminist and women’s movement, civil war and the theology of life.

Inhibition of global warming has become one of the major goals for the coming decades. A key strategy is to replace fossil fuels with more sustainable fuels, which has generated growing interest in the use of waste-derived fuels and of biomass fuels. However, from the chemical point of view, biomass is an inhomogeneous fuel, usually with a high concentration of water and considerable amounts of potassium and chlorine, all of which are known to affect the durability of superheater tubes. To slow down or reduce corrosion, power plants using biomass as fuel have been forced to operate at lower steam temperatures as compared to fossil fuel power plants. This reduces power production efficiency: every 10°C rise in the steam temperature results in an approximate increase of 2% in power production efficiency. More efficient ways to prevent corrosion are needed so that power plants using biomass and waste-derived fuels can operate at higher steam temperatures. The aim of this work was to shed more light on the alkali-induced corrosion of superheater steels at elevated temperatures, focusing on potassium chloride, the alkali salt most frequently encountered in biomass combustion, and on potassium carbonate, another potassium salt occasionally found in fly ash. The mechanisms of the reactions between various corrosive compounds and steels were investigated. Based on the results, the potassium-induced accelerated oxidation of chromia protected steels appears to occur in two consecutive stages. In the first, the protective chromium oxide layer is destroyed through a reaction with potassium leading to the formation of intermediates such as potassium chromate (K2CrO4) and depleting the chromium in the protective oxide layer. As the chromium is depleted, chromium from the bulk steel diffuses into the oxide layer to replenish it. In this stage, the ability of the material to withstand corrosion depends on the chromium content (which affects how long it takes the chromium in the oxide layer to be depleted) and on external factors such as temperature (which affects how fast the chromium diffuses into the protective oxide from the bulk steel). For accelerated oxidation to continue, the presence of chloride appears to be essential.

Rahanpesu on rikollisesta toiminnasta hankitun varallisuuden siirtoa lailliseen talousjärjestelmään. Rahanpesu on liitännäinen teko ja se edellyttää aina esirikosta. Esirikos voi olla mikä tahansa rikos, josta varallisuutta hankitaan - huumausainerikos tai talousrikos. Tutkielmassa on selvitetty lainopillista menetelmää käyttäen Suomen rahanpesulain ja ilmoitusmenettelyn tavoitteita ja sisältöä, sekä kansainvälisen rahanpesusäännöstön vaikutuksia Suomen säännöstöön. Empiiristä aineistoa kerättiin teemahaastattelujen avulla ja sen avulla selvitettiin, miten Suomen ilmoitusvelvolliset noudattavat laissa ja ilmoitusmenettelyssä asetettuja velvollisuuksia käytännössä. Tutkimustulosten mukaan, ilmoitusvelvollisiin kohdistetaan suora normatiivinen ohjaus. Ilmoitusvelvolliset noudattavat, hyväksyvät sääntelyn ja uskovat siihen. Tämä auttaa Suomen viranomaisia rahanpesutorjuntatyössä. Suomen rahanpesusäännöstöä on kehitetty vuosien aikana vastamaan kansainvälisiä vaatimuksia. Sääntelyssä on vielä puutteita. On olemassa myös muita ulkopuolisia tekijöitä, jotka hankaloittavat rahanpesun tehokasta torjuntaa.

All aerobic organisms have to deal with the toxicity of oxygen. Oxygen enables more efficient energy production compared to anaerobic respiration or fermentation, but at the same time reactive oxygen species (ROS) are being formed. ROS can also be produced by external factors such as UV-radiation and contamination. ROS can cause damage to biomolecules such as DNA, lipids and proteins and organisms try to keep the damage as small as possible by repairing biomolecules and metabolizing ROS. All ROS are not harmful, because they are used as signaling molecules. To cope against ROS organism have an antioxidant (AOX) system which consists both enzymatic and non-enzymatic AOX defense. Some AOX are produced by the organism itself and some are gained via diet. In this thesis I studied environmentally caused changes in the redox regulation of different wild vertebrate animals to gain knowledge on the temporal, spatial and pollution-derived-effects on the AOX systems. As study species I used barn swallow, ringed seal and the Baltic salmon. For the barn swallow the main interest was the seasonal fluctuation in the redox regulation and its connection to migration and breeding. The more contaminated ringed seals of the Baltic Sea were compared to seals from cleaner Svalbard to investigate whether they suffered from contaminant induced oxidative stress. The regional and temporal variation in redox regulation and regional variation in mRNA and protein expressions of Baltic salmon were studied to gain knowledge if the salmon from different areas are equally stressed. As a comparative aspect the redox responses of these different species were investigated to see which parts of the AOX system are substantial in which species. Certain parts of AOX system were connected to breeding and others to migration in barn swallows, there was also differences in biotransformation between birds caught from Africa and Finland. The Baltic ringed seal did not differ much from the seals from Svalbard, despite the difference in contaminant load. A possible explanation to this could be the enhanced AOX mechanisms against dive-associated oxidative stress in diving air-breathing animals, which also helps to cope with ROS derived from other sourses. The Baltic salmon from Gulf of Finland (GoF) showed higher activities in their AOX defense enzymes and more oxidative damage than fish from other areas. Also on mRNA and proteomic level, stress related metabolic changes were most profound in in the fish from GoF. Mainly my findings on species related differences followed the pattern of mammals showing highest activities and least damage and birds showing lower activities and most damage, fish being intermediate. In general, the glutathione recycling-related enzymes and the ratio of oxidized and reduced glutathione seemed to be the most affected parameters in all of the species.
