Core Competence of a Small or Medium Sized Content Providing Company Operating in the Information and Communication Technologies Secto

Tutkimuksen tavoitteena on tarkastella tekijöitä, joista ydinosaaminen muodostuu, sekä sitä kuinka yritykset voisivat parhaiten hyödyntää omia resurssejaan ja osaamistaan tunnistetun ydinosaamisen avulla. Teoria osuudessa käydään läpi kuinka ydinosaaminen on kirjallisuudessa määritelty ja miten yritykset voivat sen määritellä sisäisesti itselleen. Empiirisessä osiossa käydään läpi Telecom Business Research Centerissä tehdyn kvantitatiivisen selvityksen pohjalta valitut kolme sisällöntuottaja case - yritystä sekä kuvataan näiden osaamista. Tiedot yrityksistä perustuvat niiden edustajille tehtyihin haastatteluihin ja heidän käsitykseensä omasta yrityksestään. Tämä näkemys on tutkimuksen kannalta äärimmäisen relevanttia, koska ydinosaamisen määrittely tehdään yrityksessä sisäisesti juuri haastatellun kaltaisten yrityksen ydintoimijoiden toimesta. Varsinaisten case -yritysten lisäksi käydään läpi käytännön tapaus action-oriented -tutkimusosuudessa. Tutkimusta ja siinä käsiteltyjä esimerkkejä tulisi hyödyntää yrityksen oman ydinosaamisselvityksen apuna prosessin varrella.

Performance Characteristics of an Axial-Flux Solid-Rotor-Core Induction Motor

The integration of electric motors and industrial appliances such as pumps, fans, and compressors is rapidly increasing. For instance, the integration of an electric motor and a centrifugal pump provides cost savings and improved performance characteristics. Material cost savings are achieved when an electric motor is integrated into the shaft of a centrifugal pump, and the motor utilizes the bearings of the pump. This arrangement leads to a smaller configuration that occupies less floor space. The performance characteristics of a pump drive can be improved by using the variable-speed technology. This enables the full speed control of the drive and the absence of a mechanical gearbox and couplers. When using rotational speeds higher than those that can be directly achieved by the network frequency the structure of the rotor has to be mechanically durable. In this thesis the performance characteristics of an axial-flux solid-rotor-core induction motor are determined. The motor studied is a one-rotor-one-stator axial-flux induction motor, and thus, there is only one air-gap between the rotor and the stator. The motor was designed for higher rotational speeds, and therefore a good mechanical strength of the solid-rotor-core rotor is required to withstand the mechanical stresses. The construction of the rotor and the high rotational speeds together produce a feature, which is not typical of traditional induction motors: the dominating loss component of the motor is the rotor eddy current loss. In the case of a typical industrial induction motor instead the dominating loss component is the stator copper loss. In this thesis, several methods to decrease the rotor eddy current losses in the case of axial-flux induction motors are presented. A prototype motor with 45 kW output power at 6000 min-1 was designed and constructed for ascertaining the results obtained from the numerical FEM calculations. In general, this thesis concentrates on the methods for improving the electromagnetic properties of an axial-flux solid-rotor-core induction motor and examines the methods for decreasing the harmonic eddy currents of the rotor. The target is to improve the efficiency of the motor and to reach the efficiency standard of the present-day industrial induction motors equipped with laminated rotors.

”Käsitteitä tarpeen mukaan". Kirjallisuustieteelliset käsitteet lukion kirjallisuudenopetuksessa

Tavoitteeni tässä tutkimuksessa oli selvittää, miten kirjallisuustieteellisiä proosa-anayysin käsitteitä opetetaan opetussuunnitelman mukaisissa lukion äidinkielen ja kirjallisuuden oppikirjoissa ja miten hyvin kokelaat hallitsivat kertoja-käsitteen tekstitaidon ylioppilaskokeessa keväällä 2007. Samalla pohdin, minkälainen kirjallisuustieteellinen käsitteistö palvelisi tekstianalyysin opetusta koulussa, koska Lukion opetussuunnitelman perusteet 2003 ja äidinkielen ylioppilaskoe edellyttävät äidinkielen ja kirjallisuuden opetukselta ja oppilailta käsitteiden käyttöä. Tutkimusaineistonani olivat kaikki kuusi käytössä olevaa lukion äidinkielen ja kirjallisuuden oppikirjaa ja 440 kpl kevään 2007 äidinkielen tekstitaidon ylioppilaskokeen vastaustekstiä. Oppikirjoja tarkastelin soveltamalla niiden arviointiin Lev S. Vygotskin ajatuksia arkikäsitteiden ja tieteellisten käsitteiden opettamisesta ja Hans Aeblin esittämiä teoreettisia malleja käsitteiden opettamisesta ja oppimisesta. Tutkimukseni osoittaa, että opetussuunnitelmassa mainittujen proosa-analyysin käsitteiden kertoja, näkökulma, motiivi, aihe ja teema opetus on epätäsmällistä. Oppikirjoissa ei ole otettu huomioon sitä, että käsitteenoppiminen on monivaiheinen prosessi. Myöskään problematiikkaa, joka aiheutuu kyseisten käsitteiden määrittelyn kirjavuudesta ja käytöstä sekä arkikielen käsitteinä että tieteellisinä käsitteinä, ei oppikirjoissa käsitellä. Sama näkyy ylioppilaskoeaineistossa: oppilaat eivät hallitse käsitettä kertoja tieteellisenä käsitteenä. Tietoisuus kirjallisuustieteellisten käsitteiden määrittelyn problematiikasta ja arkikäsitteiden ja tieteellisten käsitteiden ontologisista kategorioista on onnistuneen käsitteenoppimisen edellytys. Kirjallisuustieteelliset käsitteet ovat metakäsitteitä, jotka edellyttävät oppilaiden metakäsitteellisen tietoisuuden ja motivaation hyödyntämistä opetuksessa, jossa olisi sovellettava monipuolisesti eri oppimiskäsitysten parhaita puolia hyödyntäviä lähestymistapoja, erilaisia pedagogisia diskursseja. Koulujen kirjallisuudenopetusta suunniteltaessa ja kirjallisuustieteellisiä käsitteitä opetettaessa on otettava huomioon niin kirjallisuustieteen kuin kasvatustieteen näkökulma. Opetussuunnitelman ja ylioppilaskokeen asettama vaatimus käsitteiden käytöstä on kohtuuton, mikäli ei sovita, miten käsitteet määritellään ja mitä käsitteitä kokelaiden oletetaan ylioppilaskokeessa hallitsevan. Kirjallisuustieteellisten käsitteiden puutteellisen opetuksen oppikirjoissa ja niiden epämääräisen käytön ylioppilaskokeen tehtävänannoissa ja arvioinnissa voi kärjistyneimmillään nähdä oppilaan oikeusturvakysymyksenä

Applying organizational core values in everyday delivery work - case Accenture

The purpose of this thesis is to study organizational core values and their application in practice. With the help of literature, the thesis discusses the implementation of core values and the benefits that companies can gain by doing it successfully. Also, ways in which companies can improve their values’ application to their everyday work are presented. The case company’s value implementation is evaluated through a survey research conducted on their employees. The true power of values lies in their application, and therefore, core values should be the basis for all organizational behavior, integrated into everything a company does. Applying values in practice is an ongoing process and companies should continuously work towards creating a more value-based organizational culture. If a company does this effectively, they will most likely become more successful with stakeholders as well as financially. Companies looking to turn their values into actions should start with a self-assessment. Employee surveys are effective in assessing the current level of value implementation, since employees have valuable, first-hand information regarding the situations and behaviors they face in their everyday work. After the self-assessment, things like management commitment, communication, training, and support are key success factors in value implementation.

Profiling the Value of Industrial Maintenance Services

Industrial maintenance can be executed internally, acquired from the original equipment manufacturer or outsourced to a service provider, and this concludes in many different kind of business relationships. To maximize the total value in a maintenance business relationship it is important to know what the partner values. The value of maintenance services can be considered to consist of value elements and the perceived total value for the customer and the service provider is the sum of these value elements. The specific objectives of this thesis are to identify the most important value elements for the maintenance service customer and provider and also to recognize where the value elements differ. The study was executed as a statistical analysis using the survey method. The data has been collected by an online survey sent to 345 maintenance service professionals in Finland. In the survey, four different types of value elements were considered: the customer’s high critical and low critical items and the service provider’s core and support service. The most valued elements by the respondents were reliability, safety at work, environmental safety, and operator knowledge. The least valued elements were asset management factors and access to markets. Statistically significant differences in value elements between service types were also found. As a managerial implication a value gap profile is presented. This Master’s Thesis is part of the MaiSeMa (Industrial Maintenance Services in a Renewing Business Network: Identify, Model and Manage Value) research project where network decision models are created to identify, model and manage the value of maintenance services.

The Effects of the Breast Cancer Mammography Screening Programme in Women aged 40 to 84 years in Turku, Finland (1987-2009)

The objective of this thesis was to evaluate whether a more extensive mammography screening programme (TurkuMSP) conducted by the city of Turku, had an effect on breast cancer (BC) incidence, survival, or mortality in years 1987 to 2009. Despite the fact that some studies have suggested a 20 percent reduction in BC mortality due to mammography screening, there are findings of harm to subjects, which are claimed to negate the benefits of screening. Thus, the aims of this study are most pertinent. A total of 176 908 screening examinations were performed in 36 000 women aged 40−74 during the years 1987−1997. In all, 685 primary BCs were found in the screened women, either screen-detected (n=531) or during screening intervals (n=154). Survival and BC recurrence rate of women with screen-detected BC was compared to 184 women with clinical BCs detected among individuals who did not take part in the screening. The invitation interval, which may influence the outcome, was studied in the age group 40 to 49 by inviting those born in even calendar years annually for mammography screening and those born in odd years, triennially. In addition, BC incidence and mortality in the total female population of Turku aged 40 to 84 years was compared with the respective figures of Helsinki and the rest of Finland, both during the pre-screening era (1976-1986) and the screening era (1987-2009). The study was designed to compare women by age groups, because women aged 50 to 59 were generally screened in all of Finland, whereas only in Turku women aged 40 to 49 and 60 to 74 were screened in addition. Data regarding cancer recurrence were derived from the Finnish Cancer Registry and data on deaths were collected from Statistics Finland. In survival analyses, screened women with invasive BC had a significantly higher survival rate than the women with clinical BC. The survival benefit started to appear already during the first follow-up years and was evident in all age groups. A marginal survival extension was also seen in screened women when BC had spread to ipsilateral axillary nodes already at diagnosis. Recurrence-free survival rate after BC treatment was significantly more favorable among the screened women compared with women with BC found clinically. The screening invitation interval did not significantly influence BC mortality in the subset of women aged 40 to 49 years. There were no consistent differences in the changes of BC incidence between Turku and the comparison areas during the screening era. In Turku, the BC mortality incidence in women aged 55−69 years was significantly lower during the screening era (from 1987 to 1997) compared with the pre-screening era, whereas no such change was found in the city of Helsinki or Tampere. When comparing the changes in incidence-based BC mortality during years 1987 to 2009 in Turku to those of Helsinki and the rest of Finland, there was a suggestion of more than 20 percent lower mortality in Turku among oldest age group (75-84 years) compared with the reference residential areas, but the differences were not consistently significant. Interpretation of the study results should be made with caution because there were no random control groups, and on the other hand, the number of cases in subgroups was fairly low to yield definite conclusions. Also due to the many statistical analyses, some of the findings may be due to chance. The results are, however, suggestive for a decrease of BC mortality in the elderly age groups due to wide mammography screening. This finding needs confirmation in further studies before recommending an expansion of mammography screening to women up to the age of 74 years

Opportunity meets uncertainty. Towards sustainable business in the Arctic region

The Arctic region is experiencing a significant change in terms of climate change and a growing economic interest towards its natural resources and emerging business opportunities. The purpose of this study is to explore how can Finnish companies create sustainable business in the Arctic. This is done by examining the arctic business environment, identifying sectors with growth potential, addressing challenges related to operating in the Arctic and suggesting how to ensure sustainability and succeed in the globally competed arctic market. The theoretical framework is based on theories of sustainable development, corporate social responsibility and the role of strategy in creating sustainable business. Empirical data was collected by using qualitative research methods: first, background knowledge was formed based on written documents and, secondly, six expert interviews were conducted in early 2014. The interviewees represented the viewpoints of companies, political decision makers and NGO’s. The analysis of the data was conducted using thematic categorization. The empirical findings of the study suggest that in order to create sustainable business in the Arctic companies should adopt a long-term perspective, embrace a holistic approach to sustainability, understand interdependencies between the dimensions of sustainability and aim at high-level engagement in responsible behavior. To succeed in the arctic market core competencies, customer needs, multivendor cooperation and long-term presence need to be invested in on a company level. In addition, to promote and advance arctic development on a national level support is needed in terms of investments in infrastructure, funding research and design, creating a regulative framework and removing barriers of trade.
