Coaching henkilöstön kehittämisen välineenä Case: Suomen Posti Oyj

Henkilöstön kehittäminen ja henkilöstön osaamisen ylläpitäminen muuttuvat yhä tärkeämmiksi tekijöiksi yrityksen menestymiselle. Coaching on yksi uusimmista ja kasvavan suosion saaneista henkilöstön kehittämisen menetelmistä, mutta samalla se on vielä hyvin tuntematon. Tämän tutkimuksen tavoitteena on selvittää mitä coaching on ja millaisia hyötyjä sen avulla voidaan saavuttaa. Tutkimuksen case-yrityksenä toimii Suomen Posti Oyj. Tutkimus on kvalitatiivinen ja se on suoritettu aineistotriangulaatiolla. Tulokset on kerätty kyselylomaketutkimuksesta ja haastatteluiden avulla ja tämän jälkeen aineistoista on tehty yhteenvetoja ja niitä on vertailtu sekä toisiinsa että kirjallisuuslähteisiin. Tulosten perusteella voidaan todeta, että coaching on yksilöllisesti räätälöitävä ja keskustelun kautta etenevä henkilöstön kehittämismuoto. Sen avulla voidaan muun muassa parantaa yksilöiden ammatti-identiteettiä ja tehostaa työskentelytapoja. Yritys puolestaan kokee coachingin edut toiminnan laadun parantumisen, henkilöstönsitouttamisen ja motivoimisen kautta.

"Soap-Bubble" visualization and quantitative analysis of 3D coronary magnetic resonance angiograms.

In order to compare coronary magnetic resonance angiography (MRA) data obtained with different scanning methodologies, adequate visualization and presentation of the coronary MRA data need to be ensured. Furthermore, an objective quantitative comparison between images acquired with different scanning methods is desirable. To address this need, a software tool ("Soap-Bubble") that facilitates visualization and quantitative comparison of 3D volume targeted coronary MRA data was developed. In the present implementation, the user interactively specifies a curved subvolume (enclosed in the 3D coronary MRA data set) that closely encompasses the coronary arterial segments. With a 3D Delaunay triangulation and a parallel projection, this enables the simultaneous display of multiple coronary segments in one 2D representation. For objective quantitative analysis, frequently explored quantitative parameters such as signal-to-noise ratio (SNR); contrast-to-noise ratio (CNR); and vessel length, sharpness, and diameter can be assessed. The present tool supports visualization and objective, quantitative comparisons of coronary MRA data obtained with different scanning methods. The first results obtained in healthy adults and in patients with coronary artery disease are presented.

Kolmiulotteinen visualisointi mikromaailman konenäköjärjestelmässä

Työssä oli tarkoituksena saada toteutettua kolmiulotteiseen visualisointiin soveltuva ohjelmisto mikrokokoluokkaa olevien kappaleiden konenäköjärjestelmään. Työssä jouduttiin myös jatkokehittämään menetelmää kolmiulotteisen kuvan hankkimiseksi yhdellä kameralla mikrokokoisesta kohteesta. Kohteen kolmiulotteisella kuvalla voitaisiin suorittaa automaattista järjestelmäohjausta. Työssä tutkittiin ja selvitettiin laitteistolla saavutettavia tarkkuuksia ja nopeuksia, sen soveltamiseksi esimerkiksi mikromanipulaattorin ohjaamiseen. Lisäksi tutkittiin erilaisia kohteita joissa voitaisiin hyödyntää kolmiulotteista visualisointia. Tällaisia kohteita on kappaleiden laadunvalvonnassa tai niiden tutkimisessa ja esittämisessä. Syvyystiedon keräävällä menetelmällä oli saavutettava riittävä nopeus, jotta sillä voitaisiin tarvittaessa ohjata reaaliaikaisesti toimilaitteita. Menetelmänä käytettiin "Depth from Focusing" -menetelmää, johon VTT:llä oli jo aiemmin kehitetty automaattinen fokusointiohjelmisto. Työn puitteissa suoritettiin laitteisto- ja menetelmäkehitystä järjestelmän nopeuttamiseksi. Visualisoinnin toteuttamisen eri mahdollisuuksia kartoitettiin ja sellainen toteutettiin rakennettuun konenäköjärjestelmään.

Portfolioajattelu ostostrategian kehittämisessä Case: VR Konserni

Tutkimuksen tavoitteena oli selvittää portfolioajattelun hyödyntämistä yrityksen ostostrategian kehittämisessä. Teoreettisen portfolioajattelun soveltamista käytännössä selvitettiin tavallisten tuotteiden ostostrategian kehittämisprosessissa kohdeyrityksessä. Tutkimus toteutettiin kuvailevana case tutkimuksena, jossa aineiston kokoaminen pohjautui aineistotriangulaatioon. Analysointi toteutettiin ostostrategian päätösprosessin kuvaamisella sekä asetettujen esioletusten toteutumisen tutkimisella. Portfolioajattelua hyödynnettiin tutkitussa konserniyhtiössä liiketoimintayksiköiden ostotoimintojen integroimisella: toteuttamalla oston yhtenäisiä toimintatapoja konsernitasolla, yhteen sovittamalla oston tietojärjestelmäratkaisuja sisäisesti sekä kytkemällä konsernin ostojärjestelmä joustavasti ostomarkkinoille. Keskeisenä tutkimustuloksena on perinteisestä aihealueen teoriasta poikkeava havainto, jonka mukaan tavallisten tuotteiden ostostrategiassa painopiste on siirtymässä spot - ostoista ja jatkuvasta kilpailuttamisesta pitkäaikaisempiin sopimuksiin ja tiiviimpään yhteistyöhön toimittajien kanssa. Tähän on vaikuttamassa erityisesti sähköisen ostamisen järjestelmien käyttöönotto.

Tutkimus on luonteeltaan laadullinen ja sen tavoitteena on tarkastella johtoryhmätyöskentelyä ja päätöksentekoa roolien ja vuorovaikutuksen kautta. Roolit perustuvat havainnointitutkimukselle Imatra Steelin Imatran terästehtaan johtoryhmässä. Tutkimuksessa on lisäksi hyödynnetty teemahaastatteluja ja yrityksen dokumentteja, ja näin ollen aineistotriangulaatiota. Tutkimuksen painotus on empiirisellä osalla. Tutkimuksen avulla todetaan, että johtoryhmätyöskentely kohdeyrityksessä on perinteitä noudattelevaa ja keskittynyt informaation jakamiseen sekä toiminnan koordinointiin. Strateginen päätöksenteko ja dynaaminen johtoryhmätyöskentely ovat vähemmän painottuneita. Päätökset johtoryhmän kokouksissa syntyvät keskustelujen tuloksena puheenjohtajan tehdessä lopullisen ratkaisun.

More than Words? An Analysis on the Language and Structure of General Election Manifestos of the British Labour Party 1983-2005

The topic of this study is the language of the educational policies of the British Labour party in the General Election manifestos between the years 1983-2005. The twenty-year period studied has been a period of significant changes in world politics, and in British politics, especially for the Labour party. The emergence educational policy as a vote-winner of the manifestos of the nineties has been noteworthy. The aim of the thesis is two-fold: to look at the structure of the political manifesto as an example of genre writing and to analyze the content utilizing the approach of critical discourse analysis. Furthermore, the aim of this study is not to pinpoint policy positions but to look at what is the image that the Labour Party creates of itself through these manifestos. The analysis of the content is done by a method of close-reading. Based on the findings, the methodology for the analysis of the content was created. This study utilized methodological triangulation which means that the material is analyzed from several methodological aspects. The aspects used in this study are ones of lexical features (collocation, coordination, euphemisms, metaphors and naming), grammatical features (thematic roles, tense, aspect, voice and modal auxiliaries) and rhetoric (Burke, Toulmin and Perelman). From the analysis of the content a generic description is built. By looking at the lexical, grammatical and rhetorical features a clear change in language of the Labour Party can be detected. This change is foreshadowed already in the 1992 manifesto but culminates in the 1997 manifesto which would lead Labour to a landslide victory in the General Election. During this twenty-year period Labour has moved away from the old commitments and into the new sphere of “something for everybody”. The pervasiveness of promotional language and market inspired vocabulary into the sphere of manifesto writing is clear. The use of the metaphors seemed to be the tool for the creation of the image of the party represented through the manifestos. A limited generic description can be constructed from the findings based on the content and structure of the manifestos: especially more generic findings such as the use of the exclusive we, the lack of certain anatomical parts of argument structure, the use of the future tense and the present progressive aspect can shed light to the description of the genre of manifesto writing. While this study is only the beginning, it proves that the combination of looking at the lexical, grammatical and rhetorical features in the study of manifestos is a promising one.

Diffusion of Administrative Innovation: TQM Implementation and Effectiveness in a Global

The main objective of this dissertation is to create new knowledge on an administrative innovation, its adoption, diffusion and finally its effectiveness. In this dissertation the administrative innovation is approached through a widely utilized management philosophy, namely the total quality management (TQM) strategy. TQM operationalizes a self-assessment procedure, which is based on continual improvement principles and measuring the improvements. This dissertation also captures the theme of change management as it analyzes the adoption and diffusion of the administrative innovation. It identifies innovation characteristics as well as organisational and individual factors explaining the adoption and implementation. As a special feature, this study also explores the effectiveness of the innovation based on objective data. For studying the administrative innovation (TQM model), a multinational Case Company provides a versatile ground for a deep, longitudinal analysis. The Case Company started the adoption systematically in the mid 1980s in some of its units. As part of their strategic planning today, the procedure is in use throughout the entire global company. The empirical story begins from the innovation adoption decision that was made in the Case Company over 22 years ago. In order to be able to capture the right atmosphere and backgrounds leading to the adoption decision, key informants from that time were interviewed, since the main target was to clarify the dynamics of how an administrative innovation develops. In addition, archival material was collected and studied, available memos and data relating to the innovation, innovation adoption and later to the implementation contained altogether 20500 pages of documents. A survey was furthermore conducted at the end of 2006 focusing on questions related to the innovation, organization and leadership characteristics and the response rate totalled up to 54%. For measuring the effectiveness of the innovation implementation, the needed longitudinal objective performance data was collected. This data included the profit unit level experience of TQM, the development of the self assessment scores per profit unit and performance data per profit unit measured with profitability, productivity and customer satisfaction. The data covered the years 1995-2006. As a result, the prerequisites for the successful adoption of an administrative innovation were defined, such as the top management involvement, support of the change agents and effective tools for implementation and measurement. The factors with the greatest effect on the depth of the implementation were the timing of the adoption and formalization. The results also indicated that the TQM model does have an effect on the company performance measured with profitability, productivity and customer satisfaction. Consequently this thesis contributes to the present literature (i) by taking into its scope an administrative innovation and focusing on the whole innovation implementation process, from the adoption, through diffusion until its consequences, (ii) because the studied factors with an effect on the innovation adoption and diffusion are multifaceted and grouped into individual, organizational and environmental factors, and a strong emphasis is put on the role of the individual change agents and (iii) by measuring the depth and consistency of the administrative innovation. This deep analysis was possible due to the availability of longitudinal data with triangulation possibilities.

Opettajan monikulttuurinen työ

Teacher's multicultural work The purpose of the present study is to explore teachers’ conceptions of their work as teachers of multicultural students. Teachers’ experiences of multicultural work and conceptions derived from them are part of the teacher’s multicultural competence which is seen as a key component of the teacher’s multicultural teachership. The teacher’s multicultural competence consists of the teacher’s cultural knowledge, pedagogical skills and experiences and attitudes related to multiculturalism. The teacher’s multicultural competence constitutes the basis on which the teacher implements multicultural education. The foundation for the teacher’s work is laid by laws and decrees, curricula, regulations issued by authorities in charge of the education of immigrant students, resources available and other demands and expectations set by the ambient society. The study was conducted in the city of Turku, Finland. The sample consisted of class teachers who taught both immigrant and majority students. Main objects of study in the theoretical part are the multicultural and pluralistic school and the multicultural teachership. The basic assumption is that the multicultural and pluralistic school forms the frame of activity in which the teacher implements multicultural teaching. The research strategy is based on methodological triangulation. The quantitative part of the study was carried out using a questionnaire typical of survey methods. The questionnaire was returned by 71 teachers. The qualitative part was conducted using theme-based interviews typical of phenomenological philosophical research. Of the total of teachers who returned the questionnaire, twelve (12) teachers were selected for interviews. According to the results, the participating teachers enjoyed their work regardless of the ample extra work caused by the students with immigrant backgrounds. The teachers experienced their work as teachers of multicultural student groups as strenuous, yet challenging. Students with immigrant backgrounds had caused many changes in the teacher’s work. The teachers regarded their multicultural skills as inadequate in relation to the demands of the work. They had not received education related to teaching students with immigrant backgrounds, but they were ready for in-service education. The teachers’ previous attitudes concerning immigrant students had been enforced. Teaching experiences strengthened the earlier, both positive and negative, attitudes. The central problems related to multiculturalism in the teacher’s work were caused by the deficient Finnish skills of the students with immigrant background. This was apparent in both teaching and learning as well as in contacts with parents. The teachers reported on relatively few inclusions of multicultural angles in their teaching. However, they believed that they could aid students with different cultural backgrounds in their integration process. At the same time they felt that their own chances to enhance the students’ cultural identities were slim. On the basis of the interviews conducted in connection with the teacher’s multicultural competence, the teachers were divided into three groups: assimilative, indeterminate and integrating multicultural teachers. The present study provides a strong indication that teachers tend to interpret multiculturalism in narrow terms. School activities, such as Finnish as a second language, first language and religious instruction, which were targeted exclusively at immigrant students were in most cases considered adequate. A holistic, cross-disciplinary, all-inclusive multicultural education that would permeate all school activities remains largely unimplemented.

Rotational assessment of distal femur and its relevance in total knee arthroplasty: analysis by magnetic resonance imaging

AbstractObjective:To define the distal femur rotation pattern in a Brazilian population, correlating such pattern with the one suggested by the arthroplasty instruments, and analyzing the variability of each anatomic parameter.Materials and Methods:A series of 101 magnetic resonance imaging studies were evaluated in the period between April and June 2012. The epidemiological data collection was performed with the aid of the institution's computed imaging system, and the sample included 52 male and 49 female patients. The measurements were made in the axial plane, with subsequent correlation and triangulation with the other plans. The posterior condylar line was used as a reference for angle measurements. Subsequently, the anatomical and surgical transepicondylar axes and the anteroposterior trochlear line were specified. The angles between the reference line and the studied lines were calculated with the aid of the institution's software.Results:The mean angle between the anatomical transepicondylar axis and the posterior condylar line was found to be 6.89°, ranging from 0.25° to 12°. For the surgical transepicondylar axis, the mean value was 2.89°, ranging from –2.23° (internal rotation) to 7.86°, and for the axis perpendicular to the anteroposterior trochlear line, the mean value was 4.77°, ranging from –2.09° to 12.2°.Conclusion:The anatomical transepicondylar angle showed mean values corresponding to the measurement observed in the Caucasian population. The utilized instruments are appropriate, but no anatomical parameter proved to be steady enough to be used in isolation.

Elämänlaatu ja iäkkäiden kaatumisten ehkäisy

Quality of life and fall prevention among the aged Improvement of quality of life is considered to be one of the most important goals of prevention, treatment and rehabilitation among the aged. The study aimed to describe and assess fall prevention interventions as a quality of life indicator, and to describe the social dimension of health-related quality of life among the aged. In addition, it aimed to assess the effects of fall prevention intervention on quality of life among the aged. The study was implemented by using a methodological triangulation. The data in the systematic review was retrieved from the databasis of medical and nursing sciences. Home-dwelling aged (n=19) participated in the qualitative study of a social dimension of quality of life. The data was gathered by the thematic interview method. The quantitative multifactorial fall prevention study comprised 591 participants, either the aged living at home or in sheltered housing, showing an increased risk of falling. Participants were randomized into an intervention or a control group. Follow-up measurements were carried out after a 12 month intervention. The data was collected by the 15D quality of life instrument and a structured questionnaire. Based on the systematic review, only in a few studies fall prevention produced positive effects on dimensions of quality of life (physical function, social function, vitality, mental health, environmental domain). Based on the thematic interview the social dimension of quality of life consisted of three themes: personal values, personal milieu and personal daily life. Based on the fall prevention program, depressive symptoms and distress decreased, managing in usual activities improved, sexual activity and phone contacts increased among men. In women, managing in usual activities improved, socializing increased and discomfort and symptoms decreased. Within the groups, self-perceived health improved among women in the intervention group and among men in the control groups. In addition, fear of falling and feelings of insecurity reduced among women in the intervention group. Personal daily life with its activities opened up new perspectives into the social dimension of good quality of life, which was emphasized especially in the interviews of the oldest participants. Multifactorial fall prevention can affect positively some physical and psychosocial dimensions of quality of life among the community-dwelling aged. Additional studies with larger sample sizes, longer follow-up periods and multiple outcome measures are needed. Fall prevention intervention may affect quality of life by different mechanisms, and the quantitative and qualitative assessment of its effects should also be included in the interventions of randomized controlled trials.

New Distance Transforms for Gray Level Image Compression

This thesis deals with distance transforms which are a fundamental issue in image processing and computer vision. In this thesis, two new distance transforms for gray level images are presented. As a new application for distance transforms, they are applied to gray level image compression. The new distance transforms are both new extensions of the well known distance transform algorithm developed by Rosenfeld, Pfaltz and Lay. With some modification their algorithm which calculates a distance transform on binary images with a chosen kernel has been made to calculate a chessboard like distance transform with integer numbers (DTOCS) and a real value distance transform (EDTOCS) on gray level images. Both distance transforms, the DTOCS and EDTOCS, require only two passes over the graylevel image and are extremely simple to implement. Only two image buffers are needed: The original gray level image and the binary image which defines the region(s) of calculation. No other image buffers are needed even if more than one iteration round is performed. For large neighborhoods and complicated images the two pass distance algorithm has to be applied to the image more than once, typically 3 10 times. Different types of kernels can be adopted. It is important to notice that no other existing transform calculates the same kind of distance map as the DTOCS. All the other gray weighted distance function, GRAYMAT etc. algorithms find the minimum path joining two points by the smallest sum of gray levels or weighting the distance values directly by the gray levels in some manner. The DTOCS does not weight them that way. The DTOCS gives a weighted version of the chessboard distance map. The weights are not constant, but gray value differences of the original image. The difference between the DTOCS map and other distance transforms for gray level images is shown. The difference between the DTOCS and EDTOCS is that the EDTOCS calculates these gray level differences in a different way. It propagates local Euclidean distances inside a kernel. Analytical derivations of some results concerning the DTOCS and the EDTOCS are presented. Commonly distance transforms are used for feature extraction in pattern recognition and learning. Their use in image compression is very rare. This thesis introduces a new application area for distance transforms. Three new image compression algorithms based on the DTOCS and one based on the EDTOCS are presented. Control points, i.e. points that are considered fundamental for the reconstruction of the image, are selected from the gray level image using the DTOCS and the EDTOCS. The first group of methods select the maximas of the distance image to new control points and the second group of methods compare the DTOCS distance to binary image chessboard distance. The effect of applying threshold masks of different sizes along the threshold boundaries is studied. The time complexity of the compression algorithms is analyzed both analytically and experimentally. It is shown that the time complexity of the algorithms is independent of the number of control points, i.e. the compression ratio. Also a new morphological image decompression scheme is presented, the 8 kernels' method. Several decompressed images are presented. The best results are obtained using the Delaunay triangulation. The obtained image quality equals that of the DCT images with a 4 x 4

Ba in Virtual Communities

Virtual communities – interactive networks in cyberspace seasoned with feelings – are a highly topical research theme. Besides academics, more and more companies ponder upon the nature and implications of the sense of virtual communities. This thesis takes a novel viewpoint on this research and examines virtual communities from virtual ba perspective. Ba is the space – in this case a virtual and a mental one, where knowledge based interaction occurs. The aim of this thesis is to clarify the concept of virtual ba, and the development and appearance of ba in virtual communities. The scientific contribution of this qualitative case study is conceptual clarification and validation of the concept of virtual ba. The empirical part of the thesis examines blogs: Internet-based communication media, using data triangulation (observation, narratives and a thematic interview). The thesis provides insights into the development of virtual ba that has also managerial relevance.
