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.

One of the aims of the study was to clarify the reliability and validity of the Job Diagnostic Survey (JDS) and the Eigenzustand (EZ) method as measures of the objective characteristics of work and short-term mental work load in the Finnish data. The reliability and validity were examined taking into consideration the theoretical backgrounds of the methods and the reliability of the measurements. The methods were used for finding out the preconditions for organisational development based on self-improvement and clarifying the impacts of working environment (organisational functioning and job characteristics) on a worker’s mental state and health. The influences were examined on a general level - regardless of individual personal or specific contextual factors. One aim was also to clarify how cognitions and emotions are intertwined and how they influence a person’s perception of the working environment. The data consisted of 15 blue-collar organisations in the public sector. The organisations were divided in target and comparison groups depending on the research frames. The data was collected by questionnaires by post. The exploratory and confirmatory factor analyses (Lisrel) were used as the main statistical methods in examining the structures of the methods and impacts between the variables. It was shown that it is possible for organisations to develop their working conditions themselves on specific preconditions. The advance of the development processes could be shown by the amount of the development activity as well as by the changes of the mental well-being (ability to act) and sick absenteeism of the personnel. It was found that the JDS and the EZ methods were reliable and valid measures in the Finnish data. It was shown that, in addition to the objective working environment (organisational functioning and job characteristics), also such a personal factor as selfesteem influences a person’s perception of mental work load. However, the influence did not seem to be direct. The importance of job satisfaction as a general indicator of perceived working conditions was emphasised. Emotional and cognitive factors were found to be functionally intertwined constituting a common factor. Organisational functioning and the characteristics of work had connections with a person’s health measured by sick absenteeism.

Tämä diplomityö käsittelee Lappeenrannan teknillisen yliopiston ja Etelä- Karjalan poliisilaitoksen yhteistä kehitysprojektia, jonka tavoitteena oli tuottaa käytäntöön vietävissä oleva kehittämissuunnitelma ulkomaalaislupa-asioiden läpäisyaikojen hallintaan. Kehitysalueita on pyritty löytämään poliisilaitoksen henkilöstön haastatteluilla ja prosessianalyyseilla. Työ sisältää teoriaosion määräaikahallinnasta, yleiskatsauksen ulkomaalaislupa-asioista Suomessa sekä selvityksen ulkomaalaislupa-asioiden tilanteesta Etelä-Karjalan poliisilaitoksella. Työssä muodostettiin kolme kehittämisteemaa: seurannan kehittäminen, prosessien ja työtapojen kehittäminen ja yhteistyön kehittäminen. Tärkein kehittämistoimi oli Excel-pohjaisen seurantajärjestelmän suunnittelu, rakentaminen ja käyttöönottaminen. Seurantajärjestelmää voidaan hyödyntää tehtävien päivittäisessä ohjauksessa, määräaikatavoitteiden toteutumisen seurannassa sekä tilannekuvan ylläpitämisessä. Tavoitetilanteessa seurantajärjestelmän avulla hallitaan tilannetta siten, että hallitsemattomia hakemusruuhkia ei synny. Hankkeesta saatuja kokemuksia tehtäväjonojen hallinnasta ja suorituskyvyn mittaamisesta voidaan ajatella hyödynnettävän myös muissa prosesseissa.

I avhandlingen undersöktes hur journalister själva reagerar efter att ha arbetat med en plötslig krissituation, samt vilka faktorer som kan bidra till en förhöjd risk för allvarliga långsiktiga stressymptom. Temat undersöktes (1) genom att se på hur journalisters tidigare erfarenheter av krisuppdrag och traumatiska upplevelser i privatlivet var relaterade till stressymptom (posttraumatiskt stressyndrom, sekundär traumatisk stress, depression och utmattningssyndrom), och (2) genom att studera riskfaktorer i en identifierad typ av kris, de finländska skolskjutningarna 2007-08. Avhandlingens resultat baserades på enkätsvar från finländska nyhetsjournalister (N = 503) och intervjuer med personer som jobbat på plats vid skolskjutningar (N = 28). En klar majoritet av journalisterna hade inte allvarliga långsiktiga stressymptom vid tiden för undersökningen. De som varit på ett tidigare krisuppdrag där man bevittnat många obehagliga detaljer hade fler allvarliga stressymptom. En annan riskfaktor var att ha ett förflutet med fler traumatiska händelser i privatlivet. Bland de som arbetat med skolskjutningar var starka kortsiktiga reaktioner, t.ex. hjälplöshet och chock, relativt vanliga. Reaktionerna hörde ändå oftast till den normala återhämtningsprocessen, och ledde inte till en långsiktig försämring av måendet. Journalister som i hög grad identifierade sig med krisen, t.ex. personer med egna barn, hade större risk för att drabbas av allvarliga symptom på lång sikt. Detsamma gällde de som på plats upplevt journalistiska etiska dilemman, t.ex. att beordras av överordnade till uppdrag som gick emot egna principer. För att förebygga psykisk stress bland journalister är det viktigt att inom branschen sprida kunskap om stressreaktioner och utveckla rekommendationer för etisk krisjournalistik. Därmed kan journalister få bättre verktyg för att minimera risken att via sitt yrkesutövande orsaka ytterligare skada åt krisdrabbade.

There are vast changes in the work environment, and the traditional rules and management methods might not be suitable for today’s employees anymore. The meaning of work is also changing due to the younger and higher educated generations entering the markets. Old customs need to be re-validated and new approaches should be taken into use. This paper strongly emphasizes the importance of happiness research and happiness at work. The values towards the meaning of work are changing; people demand happiness and quality from all aspects of their lives. The aim of this study is to define happiness - especially at work - and to explain how it can be measured and what kind of results achieved. I also want to find out how the contents of work and the working environment might enhance happiness. The correlation between education and happiness is discussed and examined. I am aware that the findings and theories are concentrating mainly on Western Countries and highlighting the values and work-environments of those societies. The main aim of the empirical study is to find out if there are connections between happiness and work in data collected by World Value Survey in 2005, and if the profession has effects on happiness. Other factors such as the correlation of age, sex, education and income are examined too. I also want to find out what kind of values people have towards work and how these affect the happiness levels. The focus is on two nations: Finland (N=1014) and Italy (N=1012). I have also taken the global comparison within, that is all 54 countries (N=66,566) included in the 5th wave (during the years 2005 -2008) of the World Value Survey. The results suggest that people are generally happy around the world; happiness decreasing with the age, the educated being happier than the uneducated and the employed happier than the unemployed. People working in neat “white collar” jobs are more likely happier than those working in factories or outdoors. Money makes us happier, until certain level is reached. Work is important to people and the importance of work adds happiness. Work is also highly appreciated, but there are more happy people among those who do not appreciate work that highly. Safety matters the most when looking for a job, and there are more happy people among those who have selected the importance of work as the first choice when looking for a job, than among those to whom an income is the most important aspect. People are more likely happy when the quality of work is high, that is when their job consists of creative and cognitive tasks and when they have a feeling of independence.

Fast changing environment sets pressure on firms to share large amount of information with their customers and suppliers. The terms information integration and information sharing are essential for facilitating a smooth flow of information throughout the supply chain, and the terms are used interchangeably in research literature. By integrating and sharing information, firms want to improve their logistics performance. Firms share information with their suppliers and customers by using traditional communication methods (telephone, fax, Email, written and face-to-face contacts) and by using advanced or modern communication methods such as electronic data interchange (EDI), enterprise resource planning (ERP), web-based procurement systems, electronic trading systems and web portals. Adopting new ways of using IT is one important resource for staying competitive on the rapidly changing market (Saeed et al. 2005, 387), and an information system that provides people the information they need for performing their work, will support company performance (Boddy et al. 2005, 26). The purpose of this research has been to test and understand the relationship between information integration with key suppliers and/or customers and a firm’s logistics performance, especially when information technology (IT) and information systems (IS) are used for integrating information. Quantitative and qualitative research methods have been used to perform the research. Special attention has been paid to the scope, level and direction of information integration (Van Donk & van der Vaart 2005a). In addition, the four elements of integration (Jahre & Fabbe-Costes 2008) are closely tied to the frame of reference. The elements are integration of flows, integration of processes and activities, integration of information technologies and systems and integration of actors. The study found that information integration has a low positive relationship to operational performance and a medium positive relationship to strategic performance. The potential performance improvements found in this study vary from efficiency, delivery and quality improvements (operational) to profit, profitability or customer satisfaction improvements (strategic). The results indicate that although information integration has an impact on a firm’s logistics performance, all performance improvements have not been achieved. This study also found that the use of IT and IS have a mediocre positive relationship to information integration. Almost all case companies agreed on that the use of IT and IS could facilitate information integration and improve their logistics performance. The case companies felt that an implementation of a web portal or a data bank would benefit them - enhance their performance and increase information integration.

In this doctoral thesis, a power conversion unit for a 10 kWsolid oxide fuel cell is modeled, and a suitable control system is designed. The need for research was identified based on an observation that there was no information available about the characteristics of the solid oxide fuel cell from the perspective of power electronics and the control system, and suitable control methods had not previously been studied in the literature. In addition, because of the digital implementation of the control system, the inherent characteristics of the digital system had to be taken into account in the characteristics of the solid oxide fuel cell (SOFC). The characteristics of the solid oxide fuel cell as well the methods for the modeling and control of the DC/DC converter and the grid converter are studied by a literature survey. Based on the survey, the characteristics of the SOFC as an electrical power source are identified, and a solution to the interfacing of the SOFC in distributed generation is proposed. A mathematical model of the power conversion unit is provided, and the control design for the DC/DC converter and the grid converter is made based on the proposed interfacing solution. The limit cycling phenomenon is identified as a source of low-frequency current ripple, which is found to be insignificant when connected to a grid-tied converter. A method to mitigate a second harmonic originating from the grid interface is proposed, and practical considerations of the operation with the solid oxide fuel cell plant are presented. At the theoretical level, the thesis discusses and summarizes the methods to successfully derive a model for a DC/DC converter, a grid converter, and a power conversion unit. The results of this doctoral thesis can also be used in other applications, and the models and methods can be adopted to similar applications such as photovoltaic systems. When comparing the results with the objectives of the doctoral thesis, we may conclude that the objectives set for the work are met. In this doctoral thesis, theoretical and practical guidelines are presented for the successful control design to connect a SOFC-based distributed generation plant to the utility grid.
