Palveluprosessin suorituskyvyn mittaaminen

Uudelle toimialalle siirtyminen tuo mukanaan yrityksille monenlaisia haasteita. Tämän työn tavoitteena on rakentaa SOL Palvelut Oy:n uusien turvatarkastuspalveluiden johdolle helppokäyttöinen suorituskykymittaristo nykytilanteen kartoittamiseen sekä päätöksenteon tukemiseen. Mittariston rakentamiseen käytetään Lappeenrannan teknillisen yliopiston kehittämää Excel-pohjaista Sake-ohjelmistoa. Lisäksi työn tarkoituksena on tarjota mittaustulosten, teorioiden sekä oman kokemuksen pohjalta muutamia kehitysehdotuksia palvelun tuottamisen parantamiseksi. Oma kokemuspohja syntyy turvatarkastajan peruskurssin suorittamisen sekä itse turvatarkastajan työn tekemisen kautta. Teoriaosuudet käsittelevät palveluiden laatujohtamista, viestintää, motivointia sekä suorituskyvyn mittaamista. Aihealueet ovat määräytyneet mittariston rakentamisen tarpeen, mittaustulosten sekä havaittujen kehityskohteiden kautta. Teorioiden lisäksi työssä tutkitaan turvatarkastuspalveluiden tuottamisen taustalla vaikuttavia tekijöitä kuten lainsäädäntöä, ilmailumääräyksiä sekä kilpailua. Työn empiriaosuus koostuu puolestaan mittariston rakentamisen vaiheista sekä varsinaisten mittaustulosten käsittelemisestä ja hyödyntämisestä. Työlle asetetut tavoitteet täyttyivät hyvin ja yrityksen johdolle kyettiin rakentamaan hyvällä pohjalla oleva suorituskyvyn mittausjärjestelmä. Nykyarvojen perusteella pystyttiin kartoittamaan yrityksen nykytilaa ja sitä kautta voitiin luoda kehitysehdotuksia toimintojen tehostamiseksi. Erityisiksi kehityskohteiksi nousivat talous, koulutus sekä henkilöstö. Näiden tulosten sekä oman työkokemuksen pohjalta työssä on käsitelty kehitysehdotuksia, jotka koskevat mm. viestintää, palkitsemista, palveluohjaajia, koulutuksen kannattavuutta sekä työvuoroja.

Diffusion of Smart Meters in Central East Europe

The present study deals with innovation diffusion as the central component of innovation process and takes smart meters as a concrete example from the electric power industry. Smart meters are seen as key enablers of the industry-wide shift towards smart grids and are recognized by the European Union as means of reaching its environmental and energy goals. However, the spread of smart meters through the market, especially in Central East Europe (CEE), is not corresponding to the expectations and identified benefits. The current work synthesizes available data for the under-researched geographical region of CEE and clarifies the process of smart meter diffusion and drivers behind it. In addition to innovation theories the methods applied are rate of adoption and thematic analysis. The results prove the large gap between optimal and actual diffusion as well as the lagging position of CEE in comparison to the EU’s market leaders. The smart metering market is driven from bottom-up and the majority of CEE countries have already carried out or started the initial activities. Therefore, in coming years more intensive smart meters deployment will be seen.

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.

A study on rate correlations of gasification reactions

Gasification offers an environmentally friendly alternative for conventional combustion enabling the use of low grade and troublesome fuel such as municipal waste. While combustion converts fuel directly into thermal energy and noxious gases, gasification thermally converts fuel into gas that can be used in multiple applications. The purpose of this work is to get to know the gasification as a phenomenon and examine the kinetics of gasification. The main interest is in the reaction rates of the most important gasification reactions - water-gas, Boudouard and shift reaction. Reaction rate correlations found in the scientific articles are examined in atmospheric pressure in different temperatures.

Mental Well-being at Work. A Sign of a Healthy Organisation and a Necessary Precondition for Organisational Development

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.

Laatu ja tuottavuus hitsaavassa verkostossa

Diplomityössä tarkastellaan laadun ja tuottavuuden parantamisen keinoja hitsaavassa verkostossa MIG/MAG-hitsauksen osalta. Työn taustalla vaikuttaa Total Welding Management -menetelmä, mikä on hitsaustoimintojen kokonaisvaltaiseen johtamiseen ja hallintaan kehitetty toimintamalli. Työn teoriaosassa käsitellään laatuajattelua ja yritysyhteistyötä hitsaavan teollisuuden yrityskentässä sekä hitsauskustannuksiin vaikuttavia tekijöitä. Tutkimusosuus sisältää yritysverkoston nykytilan tarkastelun sekä kehitystoimenpiteitä kohti verkoston yhteistä toimintamallia saavuttaa tehokas ja kannattava yhteistyö. Hitsaustyön kustannukset määritetään suurelta osin suunnittelussa. Laatuun voidaan vaikuttaa merkittävästi hitsaustyötä edeltävissä toiminnoissa sekä hitsaajan työn tukemisella. Kokonaisvaltaisen hyödyn saavuttaminen hitsaustyön tuottavuuden parantamisessa vaatii kaikkien toimintojen tarkastelua sen sijaan, että tehostetaan vain hitsaamon toimintaa. Itse hitsaus voi olla vain pieni osa hitsaustoimintojen kokonaishallintaa. Toimintamallin luominen laadunvarmistukseen, suunnittelun ja valmistuksen yhteistyöhön sekä hitsaustoimintojen hallintaan mahdollistaa hitsaavan verkoston toiminnan tehostamisen sekä laadun paranemisen. Tämä saavutetaan viemällä toimintamalli osaksi jokapäiväistä työtä, lähelle valmistusta, ja ohjeistamalla, että jokainen tietää kuinka toimia. Esimerkiksi työssä tarkastellun yhden tuotteen osalta ohjeistus turhan työn vähentämiseksi tuotti 19 % tuotannon kasvun työvuoron aikana. Tilaus-toimitusketjun tuottavuuteen ja kannattavuuteen voidaan vaikuttaa merkittävästi käymällä läpi konkreettisesti valmistettavat tuotteet ja niihin liittyvät toiminnot. Diplomityössä tehtyjen tarkastelujen ja havaintojen avulla käytännön työ tulee jatkumaan yritysverkostossa tapahtuvassa kehitystyössä.

Work-related crisis exposure : psychological trauma and PTSD in news journalists

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.

Work for your happiness - Theoretical and empirical study defining and measuring happiness at work

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.

Biodiversity and ecosystem functioning in angiosperm communities in the Baltic Sea

The biological variation in nature is called biodiversity. Anthropogenic pressures have led to a loss of biodiversity, alarming scientists as to what consequences declining diversity has for ecosystem functioning. The general consensus is that diversity (e.g. species richness or identity) affects functioning and provides services from which humans benefit. The aim of this thesis was to investigate how aquatic plant species richness and identity affect ecosystem functioning in terms of processes such as primary production, nutrient availability, epifaunal colonization and properties e.g. stability of Zostera marina subjected to shading. The main work was carried out in the field and ranged temporally from weeklong to 3.5 months-long experiments. The experimental plants used frequently co-occur in submerged meadows in the northern Baltic Sea and consist of eelgrass (Z. marina), perfoliate pondweed (Potamogeton perfoliatus), sago pondweed (P. pectinatus), slender-leaved pondweed (P. filiformis) and horned pondweed (Zannichellia palustris). The results showed that plant richness affected epifaunal community variables weakly, but had a strong positive effect on infaunal species number and functional diversity, while plant identity had strong effects on amphipods (Gammarus spp.), of which abundances were higher in plant assemblages consisting of P. perfoliatus. Depending on the starting standardizing unit, plant richness showed varying effects on primary production. In shoot density-standardized plots, plant richness increased the shoot densities of three out of four species and enhanced the plant biomass production. Both positive complementarity and selection effects were found to underpin the positive biodiversity effects. In shoot biomass-standardized plots, richness effects only affected biomass production of one species. Negative selection was prevalent, counteracting positive complementarity, which resulted in no significant biodiversity effect. The stability of Z. marina was affected by plant richness in such that Z. marina growing in polycultures lost proportionally less biomass than Z. marina in monocultures and thus had a higher resistance to shading. Monoculture plants in turn gained biomass faster, and thereby had a faster recovery than Z. marina growing in polycultures. These results indicate that positive interspecific interactions occurred during shading, while the faster recovery of monocultures suggests that the change from shading stress to recovery resulted in a shift from positive interactions to resource competition between species. The results derived from this thesis show that plant diversity affects ecosystem functioning and contribute to the growing knowledge of plant diversity being an important component of aquatic ecosystems. Diverse plant communities sustain higher primary productivity than comparable monocultures, affect faunal communities positively and enhance stability. Richness and identity effects vary, and identity has generally stronger effects on more variables than richness. However, species-rich communities are likely to contain several species with differing effects on functions, which renders species richness important for functioning. Mixed meadows add to coastal ecosystem functioning in the northern Baltic Sea and may provide with services essential for human well-being.

Towards combining interactive mobile TV and smart spaces : architectures, tools and application development

Technological developments in microprocessors and ICT landscape have made a shift to a new era where computing power is embedded in numerous small distributed objects and devices in our everyday lives. These small computing devices are ne-tuned to perform a particular task and are increasingly reaching our society at every level. For example, home appliances such as programmable washing machines, microwave ovens etc., employ several sensors to improve performance and convenience. Similarly, cars have on-board computers that use information from many di erent sensors to control things such as fuel injectors, spark plug etc., to perform their tasks e ciently. These individual devices make life easy by helping in taking decisions and removing the burden from their users. All these objects and devices obtain some piece of information about the physical environment. Each of these devices is an island with no proper connectivity and information sharing between each other. Sharing of information between these heterogeneous devices could enable a whole new universe of innovative and intelligent applications. The information sharing between the devices is a diffcult task due to the heterogeneity and interoperability of devices. Smart Space vision is to overcome these issues of heterogeneity and interoperability so that the devices can understand each other and utilize services of each other by information sharing. This enables innovative local mashup applications based on shared data between heterogeneous devices. Smart homes are one such example of Smart Spaces which facilitate to bring the health care system to the patient, by intelligent interconnection of resources and their collective behavior, as opposed to bringing the patient into the health system. In addition, the use of mobile handheld devices has risen at a tremendous rate during the last few years and they have become an essential part of everyday life. Mobile phones o er a wide range of different services to their users including text and multimedia messages, Internet, audio, video, email applications and most recently TV services. The interactive TV provides a variety of applications for the viewers. The combination of interactive TV and the Smart Spaces could give innovative applications that are personalized, context-aware, ubiquitous and intelligent by enabling heterogeneous systems to collaborate each other by sharing information between them. There are many challenges in designing the frameworks and application development tools for rapid and easy development of these applications. The research work presented in this thesis addresses these issues. The original publications presented in the second part of this thesis propose architectures and methodologies for interactive and context-aware applications, and tools for the development of these applications. We demonstrated the suitability of our ontology-driven application development tools and rule basedapproach for the development of dynamic, context-aware ubiquitous iTV applications.
