Tässä työssä on tarkasteltu työyhteisön hyvinvointia ja työilmapiiriä tulehduttavia tekijöitä case yrityksessä. Tutkielman tavoitteena on ollut löytää tiedonkulun ja tiimityöskentelyn ongelmiin ratkaisuja. Tutkimusmenetelmänä on käytetty laadullista tutkimusta ja empiirinen materiaali koostuu avoimen anonyymi-kyselyn vastauksien sisällöstä. Kyselyn tuloksista merkittävimmiksi ongelma-alueiksi työyhteisössä muodostuivat tiedonkulun heikkous ja keskinäisen arvostuksen puute. Erityisen positiivisiksi asioiksi työntekijät kokivat fyysisen työturvallisuuden ja luottamuksen työn jatkuvuuteen. Henkilöstövoimavarojen johtamisen vaatimusten kasvaessa muuttuvan liiketoiminnan mukana on erityisesti pienien pk-yrityksen kiinnitettävä huomiota henkilöstöosaston toimintaan ja työlainsäädännön vaateisiin. Yritysten yhä enemmän panostaessa ydinosaamiseensa, korostuu henkilöstöhankinnassa ja henkilöstöjohtamisessa alan erityisosaajien sitouttaminen. Nykypäivänä työntekijät eivät enää motivoidu ainoastaan palkan suuruudesta, vaan vaativat sitoutumisensa vastapainoksi työhyvinvointiin panostamista. Huonon työilmapiirin vallitessa ihmiset alkavat helposti suhtautua työhön ulkokohtaisesti eivätkä halua jakaa omaamaansa tietoa muille.

Matkustajat pitävät junissa annettavaa informaatiota entistä tärkeämpänä. Tähän haasteeseen pyritään vastaamaan rutiinikuulutusten, kuten asemille tulokuulutusten, automatisoinnilla. Kuulutukset soitetaan ääneen ja esitetään tekstinä näytöillä. Tällöin annettava informaatio on selkeää ja tasalaatuista myös vieraalla kielellä. Junan tiedot, kuten määränpää ja vaunun myyntinumero, esitetään junan ulkoseinällä ovien vierellä junaan nousevia matkustajia varten. Tässä diplomityössä luodaan yleiskatsaus junaväylään liittyviin standardeihin, TCN-standardiin ja UIC-556-määrelehteen. Yleiskatsauksen lisäksi käsitellään tarkemmin matkustajainformaatiojärjestelmään liittyvät osat. Tutustumme myös UIC-176-määrelehteen, joka käsittelee matkustajainformaatiojärjestelmän näyttöjä. Luomme yleiskatsauksen EKE-Elektroniikka Oy:n kehittämään modulaariseen junanhallintajärjestelmään. Työssä suunnitellaan asiakkaan ja standardien vaatimusten pohjalta matkustajainformaatiojärjestelmä, joka on integroitu junanhallintajärjestelmään. Tekstitiedon välittämiseen vaunusta toiseen käytetään WTB-junaväylää. Siinä kommunikoidaan UIC-556-määrelehden mukaisesti, joka mahdollistaa eurooppalaisen yhteensopivuuden. Työn tuloksena on määritelty järjestelmän fyysinen rakenne, ohjelmistorakenne, vaadittavat tietokannat, tiedon syöttäminen järjestelmälle ja junaväylässä käytettävät telegrammit. Erityishaasteena on ratkaistu tilanne, jossa juna jakautuu matkan varrella useampaan suuntaan.

Technology scaling has proceeded into dimensions in which the reliability of manufactured devices is becoming endangered. The reliability decrease is a consequence of physical limitations, relative increase of variations, and decreasing noise margins, among others. A promising solution for bringing the reliability of circuits back to a desired level is the use of design methods which introduce tolerance against possible faults in an integrated circuit. This thesis studies and presents fault tolerance methods for network-onchip (NoC) which is a design paradigm targeted for very large systems-onchip. In a NoC resources, such as processors and memories, are connected to a communication network; comparable to the Internet. Fault tolerance in such a system can be achieved at many abstraction levels. The thesis studies the origin of faults in modern technologies and explains the classification to transient, intermittent and permanent faults. A survey of fault tolerance methods is presented to demonstrate the diversity of available methods. Networks-on-chip are approached by exploring their main design choices: the selection of a topology, routing protocol, and flow control method. Fault tolerance methods for NoCs are studied at different layers of the OSI reference model. The data link layer provides a reliable communication link over a physical channel. Error control coding is an efficient fault tolerance method especially against transient faults at this abstraction level. Error control coding methods suitable for on-chip communication are studied and their implementations presented. Error control coding loses its effectiveness in the presence of intermittent and permanent faults. Therefore, other solutions against them are presented. The introduction of spare wires and split transmissions are shown to provide good tolerance against intermittent and permanent errors and their combination to error control coding is illustrated. At the network layer positioned above the data link layer, fault tolerance can be achieved with the design of fault tolerant network topologies and routing algorithms. Both of these approaches are presented in the thesis together with realizations in the both categories. The thesis concludes that an optimal fault tolerance solution contains carefully co-designed elements from different abstraction levels

Työssä haluttiin selvittää sellutehdasorganisaation sisäisen viestinnän nykytilaa ja siihen liittyviä haasteita. Lisäksi selvitettiin mitä viestintäkanavia ja -käytäntöjä tuotantotoimintaan liittyy ja miten niitä tulisi kehittää. Tutkimuksessa käytettiin kvalitatiivista tutkimusotetta. Tutkimusaineisto kerättiin henkilökohtaisten teemahaastattelujen sekä ryhmähaastattelujen avulla. Teemahaastattelujen aineisto litteroitiin ja analysoitiin teema-alueitten mukaisesti. Ryhmähaastattelujen aineisto saatiin kirjaamalla olennaisimmat asiat keskustelujen aikana. Lopuksi saatu materiaali luokiteltiin ryhmiin haastattelukysymyksiin perustuen. Tutkimuksessa saatiin selkeä käsitys siihen mitä kanavia pitkin ja miten tuotanto-organisaatio viestii tällä hetkellä. Eri viestintäkanavien hyötyjen ja heikkouksien määrittämisen kautta voitiin arvioida mihin suuntaan viestinnän kehittämistä tulisi suunnata. Tulosten perusteella määriteltiin toimenpiteet, joiden kautta organisaatio saa parannettua tiedon kulun läpinäkyvyyttä ja lisättyä vuorovaikutusta organisaation eri toimijoiden välillä. Toimenpidesuositusten mukaan organisaation tulisi hyödyntää tehokkaammin käytössä olevaa sähköistä raportointijärjestelmää sekä kehittää palaveritoimintoja. Palautteenantoa, eli viestinnän kaksisuuntaisuutta tulisi korostaa, koska se vahvistaa ja ohjaa haluttua toimintaa. Tänä päivänä yritysten viestinnälliset tarpeet korostavat yhä enemmän yksilöllisiä vuorovaikutus- ja kommunikointitaitoja. Näiden taitojen osaamisen ja ymmärtämisen kautta on vasta mahdollista käyttää tehokkaasti viestintäteknologian tuomia etuja työyhteisöissä. Nämä taidot ovat myös pohjana muutostilanteista selviytymiselle.

Aktiivinen ja kehittyvä viestintä on välttämätöntä kaikille organisaatioille. Osuustoiminnassa sillä on erityinen merkitys, koska asiakas, omistaja ja jopa työntekijä on sama henkilö. Tämän pro gradu-tutkielman tarkoitukse-na oli selvittää, kuinka viestintää ja vuorovaikutusta voisi kehittää Jukolan Osuuskaupassa. Osuuskaupan eri ryhmät eli asiakasomistajat, työntekijät, esimiehet, toimi-tusjohtaja, hallinto, asiakastoimikunta ja osuuskunnan kokous ovat tärkeitä viestintään ja vuorovaikutukseen osallistujia. Työssä tarkasteltiin sisäistä viestintää sekä viestintää osuuskaupan ja asiakasomistajien välillä. Empi-riaosuutta varten haastateltiin seitsemää työntekijää ja viittä esimiestä. Hallinnon jäsenille kysymykset lähetettiin sähköpostilla ja asiakastoimi-kunnan jäsenille postitse. Tutkimus osoitti, että asiakasomistajien suorissa ja epäsuorissa vaikutta-mismahdollisuuksissa on kehitettävää. Myös palveluun ja emotionaaliseen viestintään vaikuttaisi olevan tarvetta panostaa. Lisäksi S-Pankin tehtäviä pidettiin monimutkaisina. Sisäisen viestinnän onnistumiseen näyttää suu-resti vaikuttavan esimiesten taidot. Henkilökunnan keskuudessa näyttäisi olevan tarvetta myös yleisille tilaisuuksille sekä paremmin kohdennetulle viestinnälle.

The purpose of this research is to draw up a clear construction of an anticipatory communicative decision-making process and a successful implementation of a Bayesian application that can be used as an anticipatory communicative decision-making support system. This study is a decision-oriented and constructive research project, and it includes examples of simulated situations. As a basis for further methodological discussion about different approaches to management research, in this research, a decision-oriented approach is used, which is based on mathematics and logic, and it is intended to develop problem solving methods. The approach is theoretical and characteristic of normative management science research. Also, the approach of this study is constructive. An essential part of the constructive approach is to tie the problem to its solution with theoretical knowledge. Firstly, the basic definitions and behaviours of an anticipatory management and managerial communication are provided. These descriptions include discussions of the research environment and formed management processes. These issues define and explain the background to further research. Secondly, it is processed to managerial communication and anticipatory decision-making based on preparation, problem solution, and solution search, which are also related to risk management analysis. After that, a solution to the decision-making support application is formed, using four different Bayesian methods, as follows: the Bayesian network, the influence diagram, the qualitative probabilistic network, and the time critical dynamic network. The purpose of the discussion is not to discuss different theories but to explain the theories which are being implemented. Finally, an application of Bayesian networks to the research problem is presented. The usefulness of the prepared model in examining a problem and the represented results of research is shown. The theoretical contribution includes definitions and a model of anticipatory decision-making. The main theoretical contribution of this study has been to develop a process for anticipatory decision-making that includes management with communication, problem-solving, and the improvement of knowledge. The practical contribution includes a Bayesian Decision Support Model, which is based on Bayesian influenced diagrams. The main contributions of this research are two developed processes, one for anticipatory decision-making, and the other to produce a model of a Bayesian network for anticipatory decision-making. In summary, this research contributes to decision-making support by being one of the few publicly available academic descriptions of the anticipatory decision support system, by representing a Bayesian model that is grounded on firm theoretical discussion, by publishing algorithms suitable for decision-making support, and by defining the idea of anticipatory decision-making for a parallel version. Finally, according to the results of research, an analysis of anticipatory management for planned decision-making is presented, which is based on observation of environment, analysis of weak signals, and alternatives to creative problem solving and communication.

Abstract—This paper discusses existing military capability models and proposes a comprehensive capability meta-model (CCMM) which unites the existing capability models into an integrated and hierarchical whole. The Zachman Framework for Enterprise Architecture is used as a structure for the CCMM. The CCMM takes into account the abstraction level, the primary area of application, stakeholders, intrinsic process, and life cycle considerations of each existing capability model, and shows how the models relate to each other. The validity of the CCMM was verified through a survey of subject matter experts. The results suggest that the CCMM is of practical value to various capability stakeholders in many ways, such as helping to improve communication between the different capability communities.

The European transport market has confronted several changes during the last decade. Due to European Union legislative mandates, the railway freight market was deregulated in 2007. The market followed the trend started by other transport modes as well as other previously regulated industries such as banking, telecommunications and energy. Globally, the first country to deregulate the railway freight market was the United States, with the introduction of the Staggers Rail Act in 1980. Some European countries decided to follow suit already before regulation was mandated; among the forerunners were the United Kingdom, Sweden and Germany. The previous research has concentrated only on these countries, which has provided an interesting research gap for this thesis. The Baltic Sea Region consists of countries with different kinds of liberalization paths, including Sweden and Germany, which have been on the frontline, whereas Lithuania and Finland have only one active railway undertaking, the incumbent. The transport market of the European Union is facing further challenges in the near future, due to the Sulphur Directive, oil dependency and the changing structure of European rail networks. In order to improve the accessibility of this peripheral area, further action is required. This research focuses on topics such as the progression of deregulation, barriers to entry, country-specific features, cooperation and internationalization. Based on the research results, it can be stated that the Baltic Sea Region’s railway freight market is expected to change in the future. Further private railway undertakings are anticipated, and these would change the market structure. The realization of European Union’s plans to increase the improved rail network to cover the Baltic States is strongly hoped for, and railway freight market counterparts inside and among countries are starting to enhance their level of cooperation. The Baltic Sea Region countries have several special national characteristics which influence the market and should be taken into account when companies evaluate possible market entry actions. According to thesis interviews, the Swedish market has a strong level of cooperation in the form of an old-boy network, and is supported by a positive attitude of the incumbent towards the private railway undertakings. This has facilitated the entry process of newcomers, and currently the market has numerous operating railway undertakings. A contrary example was found from Poland, where the incumbent sent old rolling stock to the scrap yard rather than sell it to private railway undertakings. The importance of personal relations is highlighted in Russia, followed by the railway market’s strong political bond with politics. Nonetheless, some barriers to entry are shared by the Baltic Sea Region, the main ones being acquisition of rolling stock, bureaucracy and needed investments. The railway freight market is internationalizing, which is perceived via several alliances as well as the increased number of mergers and acquisitions. After deregulation, markets seem to increase the number of railway undertakings at a rather fast pace, but with the passage of time, the larger operators tend to acquire smaller ones. Therefore, it is expected that in a decade’s time, the number of railway undertakings will start to decrease in the deregulation pioneer countries, while the ones coming from behind might still experience an increase. The Russian market is expected to be totally liberalized, and further alliances between the Russian Railways and European railway undertakings are expected to occur. The Baltic Sea Region’s railway freight market is anticipated to improve, and, based on the interviewees’ comments, attract more cargoes from road to rail.

With caring science as its foundation and by means of the perioperative dialogue, the intended contribution and overall aim of this present thesis is to describe what play is and could be in the caring reality, an ideal model. The perioperative dialogue is the nurse anaesthetists’ pre-, intra- and post-operative dialogues with the children they care for in connection with anesthesia. The thesis is composed according to Schopenhauer’s notion that the road to science presupposes the world seen as performances, and has an all-pervading hermeneutic approach. The performances of the thesis are: the performance of all performances, the empirical performance, the transcendental performance and the universal performance. The performance of all performances originates in the theoretical perspective of the thesis and describes what play and its characteristics are. This performance is realized through the hermeneutic interpretation of the etymology and original meaning of the word play along with texts from caring science, philosophy, anthropology and the history of religion. The empirical performance originates in four empirical studies where caring is organized as a perioperative dialogue. In study I, the material was collected with the help of participating observations and semi-structured interviews, in study II, with the help of the critical incident method and in study III, with the help of conversation interviews. In study IV, play develops into a clinical caring science research method. The research participants consist of children with special needs, children with a pronounced fear of anaesthesia, parents of children with severe autism and nurse anaesthetists. The empirical performance relates in what way play manifests in a perioperative child context by interpreting the results from the empiric in the light of the characteristics of play. The transcendental performance is enacted in the playhouse of health and presents a picture of the essence of play, the playing. In the playhouse of health, the light, winged movement of play is actualized when what was previously too difficult, too heavy and pinioned instead is as easy as anything. The eye of love and compassion knows the art of deciphering the secret script where the Other’s holiness resides, even if mere glimpses of it appear. The universal performance depicts three caring acts where the entrance consists of entering play, the ideal of which is realized in the unmasked openness face to face, that which protects the playing human being against encroachment and an unwanted audience. In the second caring act, entering play plays on to the finely-tuned interplay between human beings in the winged play of beauty and dignity. In the third caring act, the world’s deepest plays are staged on the stage of caring, in the sense that the innermost being of each individual, the universal will joins in and allows individuals to live as playing human beings who are at home with themselves and the world. The captivating, graceful and friendly play works from within itself, as long as it illumined by the light of claritas can play undisturbed on the stage of caring where it – like an unclouded mirror of its own ideal watches over children’s health.

Tutkimuksen tarkoituksena oli selvittää, mitkä tekijät vaikuttavat henkilöstön sitoutumiseen muutoksessa. Tutkimuksen teoriaosiossa käsitellään ensiksi muutossitoutumista vahvistavia ja siinä huomioitavia tekijöitä muutosprosessissa onnistuneen muutosjohtamisen kautta, jonka jälkeen syvennytään niihin tekijöihin jotka erityisesti vaikuttavat henkilöstön muutossitoutumiseen. Tutkimuksen empiirisen aineiston muodostivat Etelä-Karjalan sosiaali- ja terveyspiirin ikäihmisten palveluiden kolmentoista henkilön haastattelut. Henkilöistä kymmenen toimi työntekijätehtävissä, kaksi lähiesimiestehtävissä sekä yksi johtoryhmässä. Haastatteluaineisto kerättiin sekä analysoitiin laadullisella tutkimusmenetelmällä. Tutkimustulokset osoittavat, että henkilöstön muutossitoutumiseen vaikuttivat eniten viestintä sekä sen ilmeneminen case-organisaation muutosprosessissa. Kaikki puutteet ja onnistuneisuudet muutosjohtamisessa kiteytyivät viestintään; henkilöstön muutossitoutumisen kannalta erityisesti esimiehen hallitsemaan viestintään ja muutosjohtajuuteen. Muutosviestinnän ollessa onnistunutta se vahvisti selkeästi henkilöstön luottamusta muutosprosessin vaiheissa ja näin lisäsi muutokseen sitoutumista.

Työssä tarkastellaan hybridi- ja sähköajoneuvojen voimankäyttöjärjestelmiä ja bussin ajomoottorina toimivan kestomagneettitahtikoneen toimintaa ja sen soveltuvuutta ajoneuvokäyttöön. Esitetään analyyttinen työkalu kestomagneettitahtikoneen induktanssisuunnittelun ja koneen vääntömomentin tuottokyvyn optimoinnin tueksi. Työkalua hyödynnetään esitettävässä ajomoottorin mitoituslaskelmassa. Työssä päätellään, että kestomagneettitahtimoottori soveltuu hyvin ajoneuvokäyttöön. Maksimaalisen vääntömomentin saavuttamiseksi sen roottorin rakenne ja induktanssit on optimoitava. Analysoimalla ajoneuvokäyttöön tarkoitettua kestomagneettitahtimoottoria työkalun avulla havaitaan, että yhtä suuremmalla induktanssisuhteella vääntömomentti on pienempi kentänheikennyksessä kuin ajettaessa konetta taajuusmuuttajalla vakioteholla nimelliskuormalla. Vastaavasti yhtä pienemmillä induktanssisuhteilla vääntömomentti on pienempi kentänheikennyksessä. Todetaan, että vääntömomentti kasvaa induktanssisuhteen poiketessa yhdestä. Suuri vääntömomentti saadaan pienillä induktanssisuhteilla. Induktanssisuhteen kasvattaminen yhdestä ei lisää moottorin tuottamaa vääntömomenttia yhtä paljon kuin induktanssisuhteen pienentäminen. Työn lopuksi verrataan työkalun laskemia tuloksia kirjallisuudesta löytyvillä yhtälöillä laskettuihin tuloksiin. Työkalun laskemat tulokset vaikuttavat ristiriidattomilta ja yhteneväisiltä teorian kanssa. Työkalun toteutuksessa tehdyt teoreettiset yksinkertaistukset aiheuttavat todennäköisesti epätarkkuutta tuloksissa erityisesti suurella kuormituksella.

The participants in the dynamic Finnish working environment are expected to display communication skills, which is emphasized when different cultures meet. The objective of this thesis was to study the required interpersonal communication competence of leaders in a Finnish-Russian superior-subordinate relationship. The leadership was approached from a communicational perspective where leadership emerges in a dyadic relationship between leader and subordinate. The research was conducted as a qualitative case study. The data was gathered from interviews in the target organization. Four superiors and five of their subordinates were interviewed. The qualitative data gathered from the interviews was analyzed by theory-driven content analysis. The representative data was organized and coded in order to establish the main categories, which form a basis of the conclusions of the thesis. Interpersonal communication competence has a significant role alongside substance in leadership. The superiors in the workplace perceive communication as contextual. The findings indicate that there are certain tensions in the relationship between the superiors and their subordinates. The tensions are described as distance, collectiveness and emotions, and verbal expression and understanding. Leadership communication competence is about finding a balance between the tensions based on cultural differences. From the interpersonal communication research tradition point of view, the efficient and appropriate communication competence in this context consists of the knowledge of tensions and challenges, as well as the ability to manage cultural tensions and the motivation to react positively to cultural differences.

Contemporary higher education operates in an environment of dwindling and parsimonious resources; the increasing need for accountability and relevance to varying stakeholders with differing expectations. These relatively new trends in higher education have been faced by business organizations which have developed different ways of operating in response. This study outlines one way by which business organizations have addressed similar circumstances to show how the Cameroon higher education (HE) could learn from business organizations to manage strategic objectives. The balanced scorecard (BSC) has been used by business organizations to address similar trends. This study evaluates the strategic objectives of Cameroonian higher education using the balanced scorecard. The system level is used to identify the general strategic objectives and one state university is used to represent the translation and implementation of the objectives at the institution level. The BSC principles used include: operational strategic objectives; organizational alignment to the strategy; making strategy everyone’s everyday job; making strategy continual and; mobilizing the leadership for change. The underlying concepts in these principles are communication, consensus, relevance, and a participatory approach. The study employs data from policy documents, relevant literature, websites and semi-structured interviews. The research approach is qualitative and the analyses are done by making meaning of phenomena in their natural contexts. The results show that there is a general knowledge of the strategic objectives but there is disagreement on the relevance of these objectives to HE and on the type of approaches used in implementing the objectives. It was also found that the relevant stakeholders are known, but not all the respondents agree on the importance of these stakeholders. All stakeholders do not have the same level of influence-the state is the most influential. Reporting is sufficiently done but there are insufficient provisions for feedback from stakeholders. The study concludes that the BSC principles can be applied to the management of strategic objectives in Cameroon HE. For Cameroonian higher education, it is recommended that the focus should be first, on developing tools for strategy before the strategy itself. Even though the need for the BSC is confirmed the context does not seem sufficiently ready to implement the BSC as a strategic management tool. The proposed BSC framework can only be used as a communication tool. The barriers to managing strategic objectives in Cameroon HE are related to the communication, consensus, clarity and relevance. However, the system has prospects for improved management and eventual adoption of the BSC as both a strategic management and communication tool. In line with other BSC applications to higher education, this study concluded that it is more feasible to apply the balanced scorecard to a single higher education institution than to a higher education system. The study makes a contribution to the BSC by showing how its principles can be used in a non-business context. The study also opens up possibilities for future research on the same topic in a different context or the same context with a wider scope (more institutions and respondents); the same study with a deeper focus on the interrelationships between the different strategic objectives (strategy maps). The study could also be extended by including the perspectives of the identified stakeholders who are not directly part of the higher education system but constitute the environment in which higher education operates.
