Several programs running on two computers were made to control the different devices of the environment. User tests were made to obtain information of needed improvements to make the simulator more realistic. Also new ideas for improving the simulator and directions of further research were obtained with the help of this research.

Implementation and Integration of New Baggage Logistic Centre at HelsinkiVantaa Airport

This thesis deals with improving international airport baggage supply chain management (SCM) by means of information technology and new baggage handling system. This study aims to focus on supply chain visibility in practice and to suggest different ways to improve the supply chain performance through information sharing. The objective is also to define how radio frequency identification (RFID) and enterprise resource planning (ERP) can make processes more transparent. In order to get full benefits from processes, effective business process management and monitoring as well as the key performance indicators must be defined, implemented and visualized through e.g. dashboard views for different roles. As an outcome of the research the need for the use of information technology systems and more advanced technologies, e.g. RFID in the supply chain management is evident. Sophisticated ERP is crucial in boosting SCM business processes and profitability. This would be beneficial for dynamic decision making as well in the airport and airline supply chain management. In the long term, economic aspects support the actions I have suggested in order to make production more flexible in reacting to quick changes.

Supplier relationship management capability in the firm's global integration

Organizing is a general problem for global firms. Firms are seeking a balance between responsiveness at the local level and efficiency through worldwide integration. In this, supply management is the focal point where external commercial supply market relations are connected with the firm's internal functions. Here, effective supplier relationship management (SRM) is essential. Global supply integration processes create new challenges for supply management professionals and new capabilities are required. Previous research has developed several models and tools for managers to manage and categorize different supplier relationship types, but the role of the firm's internal capability of managing supplier relationships in their global integration has been a clearly neglected issue. Hence, the main objective of this dissertation is to clarify how the capability of SRM may influence the firm's global competitiveness. This objective is divided into four research questions aiming to identify the elements of SRM capability, the internal factors of integration, the effect of SRM capability on strategy and how SRM capability is linked with global integration. The dissertation has two parts. The first part presents the theoretical approaches and practical implications from previous research and draws a synthesis on them. The second part comprises four empirical research papers addressing the research questions. Both qualitative and quantitative methods are utilized in this dissertation. The main contribution of this dissertation is that it aggregates the theoretical and conceptual perspectives applied to SRM research. Furthermore, given the lack of valid scales to measure capability, this study aimed to provide a foundation for an SRM capability scale by showing that the construct of SRM capability is formed of five separate elements. Moreover, SRM capability was found to be the enabler in efforts toward value chain integration. Finally, it was found that the effect of capability on global competitiveness is twofold: it reduces conflicts between responsiveness and integration, and it creates efficiency. Thus, by identifying and developing the firm's capabilities it is possible to improve performance, and hence, global competitiveness.

Introducing Continuous Integration for C and C++ Software Development Projects on Linux Platform

Software integration is a stage in a software development process to assemble separate components to produce a single product. It is important to manage the risks involved and being able to integrate smoothly, because software cannot be released without integrating it first. Furthermore, it has been shown that the integration and testing phase can make up 40 % of the overall project costs. These issues can be mitigated by using a software engineering practice called continuous integration. This thesis work presents how continuous integration is introduced to the author's employer organisation. This includes studying how the continuous integration process works and creating the technical basis to start using the process on future projects. The implemented system supports software written in C and C++ programming languages on Linux platform, but the general concepts can be applied to any programming language and platform by selecting the appropriate tools. The results demonstrate in detail what issues need to be solved when the process is acquired in a corporate environment. Additionally, they provide an implementation and process description suitable to the organisation. The results show that continuous integration can reduce the risks involved in a software process and increase the quality of the product as well.

Financial integration and TARGET2-Securities – A stakeholder approach

The purpose of this study was to analyze how different stakeholders, such as the European Central Bank, the European Commission, the European Central Securities Depositories Association, the Bank of International Settlements and the International Monetary Fund, have influenced the European financial integration in the area of securities clearing and settlement since the introduction of the single currency. The results show that the contribution differs from stakeholder to another and can take the form of standards and recommendations, legislation, research and publications, risk analysis etc. The Eurosystem has been particularly active in this area by proving and planning central bank services, such as TARGET2, CCMB2 and T2S. Along the way the development has and continues to face challenges that need to be solved by European authorities. Coordination is a key factor for the future as we have seen during the recent financial turmoil.

Integration und Vermittlung landeskundlicher Inhalte im Fremdsprachenunterricht

Tämän väitöskirjatyön aiheena on maantuntemuksellisten sisältöjen integrointi ja välittäminen vieraan kielen opetuksessa. Maantuntemuksellisilla sisällöillä tarkoitetaan vieraan kielen opetuksessa ei-kielellisiä sisältöjä, jotka ylittävät pelkän kielitiedon, kieliopin ja sanaston, välittämisen rajat. Tutkimuskirjallisuudessa näitä ei-kielellisiä sisältöjä nimitetään monin eri tavoin, esimerkiksi maantuntemukseksi (Landeskunde), sosiokulttuurisiksi tiedoiksi ja taidoiksi (soziokulturelles Wissen) tai yksinkertaisesti kulttuuriksi (Kultur). Väitöskirjatyö jakautuu teoreettiseen kehykseen (luvut 1–4), julkaistujen artikkeleiden tutkimusmetodien ja tuloksien käsittelyyn (luvut 5–6) sekä julkaistuihin artikkeleihin. Teoreettisen kehyksen ensisijaisia tutkimuskysymyksiä ovat, miten maantuntemuksellisten sisältöjen välittäminen konkretisoituu eri näkökulmista (opettajat, oppijat, oppimateriaalit) tarkasteltuna, miten kulttuurienvälinen maantuntemus ilmentyy vieraan kielen opetuksessa ja mitkä sisällöt ovat merkittäviä vieraan kielen opetuksessa. Metodisina lähestymistapoina tutkimuksessa on käytetty oppikirja-analyysiä, opetuksen tarkkailua sekä kyselytutkimuksia. Liitteenä oleville julkaistuille artikkeleille on yhteistä se, että jokainen niistä käsittelee jotakin erityistä maantuntemuksellisiin sisältöihin liittyvää aihetta empiriisestä näkökulmasta erityisesti saksan kielen opetuksen kannalta. Artikkelien tutkimusongelmia ovat kulttuuristen ja kielellisten sisältöjen yhdistäminen, kulttuurienvälisen viestinnän konkretisoituminen, kielellisen ja kulttuurisen variaation huomioiminen, stereotyyppien asema sekä sukupuolierojen merkitys vieraan kielen opetuksessa. Väitöskirjatyön teoreettisessa kehyksessä luodaan aluksi historiallinen katsaus maantuntemuksen asemaan vieraan kielen opetuksessa ja selvitetään tarkemmin erityisesti vieraan kielen didaktiikan uusimpien traditioiden, kuten konstruktivismin ja sosiokulttuurisen teorian, yhteyttä maantuntemuksen oppimiseen. Tässä yhteydessä käsitellään myös kulttuurienvälisen oppimisen traditiota ja maantuntemusta sen sovellusalueena. Tämän lisäksi selvitetään konkreettisia vieraan kielen opetuksessa ilmeneviä maantuntemukseen liittyviä didaktis-metodisia kysymyksiä, erityisesti opettajan roolia ja sitä, miten kulttuurienvälisen tradition mukainen maantuntemuksen välittäminen konkretisoituu yhtäältä yksittäisinä tehtävinä ja harjoituksina sekä toisaalta elektronisten viestimien välityksellä. Teoreettisen kehyksen ytimen muodostaa maantuntemuksellisten aiheiden valintaan ja merkittävyyteen liittyvä tutkimuskirjallisuuden pohjalta tehtävä pohdinta. Vieraan kielen opetuksessa kieliopilliset sisällöt opetetaan pääosin vakiintuneessa järjestyksessä, mutta maantuntemuksellisten sisältöjen opettamisessa ja oppimisessa ei ole säännönmukaisuuksia. Yhteenvetona esitetään teesejä, joiden tarkoituksena on antaa ehdotuksia, suosituksia ja didaktisia neuvoja maantuntemuksen opetukseen ja oppimiseen. Väitöskirjatyössä paneudutaan vaikeuksiin määritellä maantuntemuksen oppimisen kannalta merkittävät aiheet erityisesti saksan kielen opetusta silmällä pitäen. Arkipäivän kulttuurin käsittelyn tärkeyteen käytännön opetuksessa viittaavat oppikirjojen aihepiirit, opettajien ja opiskelijoiden käsitykset sekä Eurooppalaisen viitekehyksen suositukset. Tutkimuksessa selvitettiin tarkemmin myös aihepiirien valintaa kohderyhmän mukaan ja kartoitettiin oppijoiden käsityksiä maantuntemuksellisista sisällöistä ja heidän näihin kohdistuvia toiveitaan. Kyselytulosten mukaan aikuisten oppijoiden mieliin jäivät saksan kielen oppitunnilla erityisesti sellaiset kulttuuriin liittyvät asiat, jotka oppijat kokivat autenttisiksi tai jotka herättivät tunnilla keskustelua ja olivat kohdekulttuurissa erilaisia kuin omassa kulttuurissa. Tutkimuksessa selvitettiin myös kulttuurienvälisen oppimisen aspekteja vieraan kielen opetuksessa ja oppimateriaaleissa, erityisesti ”oman” ja ”vieraan” kulttuurin kokemisesta ja niiden vastakkainasettelusta. Näyttää siltä, että kulttuurienvälisen oppimisen mahdollisuudet tutkimissani saksan kielen oppikirjoissa rajoittuvat siihen, että oppijoille tarjotaan mahdollisuus eläytyä kohdekulttuurin arkeen oppikirjojen henkilöiden kautta ja että oppijoita kehotetaan kertomaan omasta kulttuuristaan. Tutkimuksessa pohditaan myös tarkemmin, voivatko sähköiset oppimateriaalit ja internet johtaa takaisin faktoihin keskittyvään maantuntemuksen oppimiseen. Virtuaaliset oppimisympäristöt, esimerkiksi oppikirjojen internetsivustot, antavat kaikesta huolimatta uusia mahdollisuuksia tutkivaan oppimiseen. Tällaisia ovat esimerkiksi ”minitutkimustehtävät” ja sellaiset harjoitustyypit, jotka eivät oppikirjoissa ole mahdollisia, kuten virtuaaliset kaupunkikierrokset. Opettajien ja oppimateriaalien laatijoiden pitäisi suunnitella sellaisia tehtäviä ja harjoituksia, jotka antavat riittävästi mahdollisuuksia myös kulttuurienväliselle pohdinnalle. Oppijan oma ja kohdekulttuuri voidaan opetuksessa nostaa samanaikaisesti esille esimerkiksi käsittelemällä kielellisiä ja kulttuurisia variaatioita. Tutkimustulosten mukaan kulttuurienvälisen oppimisen traditionkin aikana maantuntemusta välitetään yhä perinteisellä tavalla faktatietoihin painottuen, eli käytännössä kieltenopetusta ohjaa vielä edelleenkin hyvin perinteinen käsitys kielestä ja kielitaidosta. Kielten opettajien koulutuksessa olisi huomioitava se, että opettajien tulisi olla kokonaisvaltaisia kulttuurin asiantuntijoita, eli myös historia, yhteiskunta, politiikka ja myös ”arkipäiväisen elämän” tuntemus ovat tärkeitä opettajan ammattitaidossa.

Integration of the Food Waste Disposer Unit to the Existing Sewage System

Among the numerous approaches to food waste treatment, the food waste disposers method (FWDs), as a newcomer, has become slowly accepted by the general public owing to the worries about its impact on the existing sewage system. This paper aims to justify the role of FWDs in the process of urbanization in order to better prepare a city to take good care of the construction of its infrastructure and the solid waste treatment. Both the literatures and the case study help to confirm that FWDs has no negative effects on the wastewater treatment plant and it is also environmental friendly by reducing the greenhouse gas emissions. In the case study, the Lappeenranta waste water treatment plant has been selected in order to figure out the possible changes to a WWTP following the integration of FWDs: the observation shows only minor changes take place in a WWTP, in case of 25% application, like BOD up 7%, TSS up 6% and wastewater flowrate up 6%, an additional sludge production of 200 tons per year and the extra yield of methane up to 10000m3 per year; however, when the utilization rate of FWD is over 75%, BOD, TSS, and wastewater flowrate will experience more significant changes, thus exerting much pressure on the existing WWTP. FWDs can only be used in residential areas or cities equipped with consummate drainage network within the service sphere of WWTP, therefore, the relevant authority or government department should regulate the installation frequency of FWDs, while promoting the accessory application of FWDs. In the meanwhile, WWTP should improve their treatment process in order to expand their capacity for sludge treatment so as to stay in line with the future development of urban waste management.

Understanding the Racial Nature of Police and Immigrant Relations In Finland. The Case of Africans in Turku

The focus of this study is to examine the role of police and immigrants’ relations, as less is known about this process in the country. The studies were approached in two different ways. Firstly, an attempt was made to examine how immigrants view their encounters with the police. Secondly, the studies explored how aware the police are of immigrants’ experiences in their various encounters and interactions on the street level. An ancillary aim of the studies is to clarify, analyse and discuss how prejudice and stereotypes can be tackled, thereby contributing to the general debate about racism and discrimination for better ethnic relations in the country. The data in which this analysis was based is on a group of adults (n=88) from the total of 120 Africans questioned for the entire study (n=45) police cadets and (n=6) serving police officers from Turku. The present thesis is a compilation of five articles. A summary of each article findings follows, as the same data was used in all five studies. In the first study, a theoretical model was developed to examine the perceived knowledge of bias by immigrants resulting from race, culture and belief. This was also an attempt to explore whether this knowledge was predetermined in my attempt to classify and discuss as well as analyse the factors that may be influencing immigrants’ allegations of unfair treatment by the police in Turku. The main finding shows that in the first paper there was ignorance and naivety on the part of the police in their attitudes towards the African immigrant’s prior experiences with the police, and this may probably have resulted from stereotypes or their lack of experience as well as prior training with immigrants where these kinds of experience are rampant in the country (Egharevba, 2003 and 2004a). In exploring what leads to stereotypes, a working definition is the assumption that is prevalent among some segments of the population, including the police, that Finland is a homogenous country by employing certain conducts and behaviour towards ethnic and immigrant groups in the country. This to my understanding is stereotype. Historically this was true, but today the social topography of the country is changing and becoming even more complex. It is true that, on linguistic grounds, the country is multilingual, as there are a few recognised national minority languages (Swedish, Sami and Russian) as well as a number of immigrant languages including English. Apparently it is vital for the police to have a line of communication open when addressing the problem associated with immigrants in the country. The second paper moved a step further by examining African immigrants’ understanding of human rights as well as what human rights violation means or entails in their views as a result of their experiences with the police, both in Finland and in their country of origin. This approach became essential during the course of the study, especially when the participants were completing the questionnaire (N=88), where volunteers were solicited for a later date for an in-depth interview with the author. Many of the respondents came from countries where human rights are not well protected and seldom discussed publicly, therefore understanding their views on the subject can help to explain why some of the immigrants are sceptical about coming forward to report cases of batteries and assaults to the police, or even their experiences of being monitored in shopping malls in their new home and the reason behind their low level of trust in public authorities in Finland. The study showed that knowledge of human rights is notably low among some of the participants. The study also found that female respondents were less aware of human rights when compared with their male counterparts. This has resulted in some of the male participants focussing more on their traditional ways of thinking by not realising that they are in a new country where there is equality in sexes and lack of respect on gender terms is not condoned. The third paper focussed on the respondents’ experiences with the police in Turku and tried to explore police attitudes towards African immigrant clients, in addition to the role stereotype plays in police views of different cultures and how these views have impacted on immigrants’ views of discriminatory policing in Turku. The data is the same throughout the entire studies (n=88), except that some few participants were interviewed for the third paper thirty-five persons. The results showed that there is some bias in mass-media reports on the immigrants’ issues, due to selective portrayal of biases without much investigation being carried out before jumping to conclusions, especially when the issues at stake involve an immigrant (Egharevba, 2005a; Egharevba, 2004a and 2004b). In this vein, there was an allegation that the police are even biased while investigating cases of theft, especially if the stolen property is owned by an immigrant (Egharevba, 2006a, Egharevba, 2006b). One vital observation from the respondents’ various comments was that race has meaning in their encounters and interaction with the police in the country. This result led the author to conclude that the relation between the police and immigrants is still a challenge, as there is rampant fear and distrust towards the police by some segments of the participating respondents in the study. In the fourth paper the focus was on examining the respondents’ view of the police, with special emphasis on race and culture as well as the respondents’ perspective on police behaviour in Turku. This is because race, as it was relayed to me in the study, is a significant predictor of police perception (Egharevba, 2005a; Egharevba and Hannikianen, 2005). It is a known scientific fact that inter-group racial attitudes are the representation of group competition and perceived threat to power and status (Group-position theory). According to Blumer (1958) a sense of group threat is an essential element for the emergence of racial prejudice. Consequently, it was essential that we explored the existing relationship between the respondents and the police in order to have an understanding of this concept. The result indicates some local and international contextual issues and assumptions that were of importance tackling prejudice and discrimination as it exists within the police in the country. Moreover, we have to also remember that, for years, many of these African immigrants have been on the receiving end of unjust law enforcement in their various countries of origin, which has resulted in many of them feeling inferior and distrustful of the police even in their own country of origin. While discussing the issues of cultural difference and how it affects policing, we must also keep in mind the socio-cultural background of the participants, their level of language proficiency and educational background. The research data analysed in this study also confirmed the difficulties associated with cultural misunderstandings in interpreting issues and how these misunderstandings have affected police and immigrant relations in Finland. Finally, the fifth paper focussed on cadets’ attitudes towards African immigrants as well as serving police officers’ interaction with African clients. Secondly, the police level of awareness of African immigrants’ distrustfulness of their profession was unclear. For this reason, my questions in this fifth study examined the experiences and attitudes of police cadets and serving police officers as well as those of African immigrants in understanding how to improve this relationship in the country. The data was based on (n=88) immigrant participants, (n=45) police cadets and 6 serving police officers from the Turku police department. The result suggests that there is distrust of the police in the respondents’ interaction; this tends to have galvanised a heightened tension resulting from the lack of language proficiency (Egharevba and White, 2007; Egharevba and Hannikainen, 2005, and Egharevba, 2006b) The result also shows that the allegation of immigrants as being belittled by the police stems from the misconceptions of both parties as well as the notion of stop and search by the police in Turku. All these factors were observed to have contributed to the alleged police evasiveness and the lack of regular contact between the respondents and the police in their dealings. In other words, the police have only had job-related contact with many of the participants in the present study. The results also demonstrated the complexities caused by the low level of education among some of the African immigrants in their understanding about the Finnish culture, norms and values in the country. Thus, the framework constructed in these studies embodies diversity in national culture as well as the need for a further research study with a greater number of respondents (both from the police and immigrant/majority groups), in order to explore the different role cultures play in immigrant and majority citizens’ understanding of police work.

Assessing Organizational Cultural Fit prior to Integration in the M&A Process

Yritysostojen määrä on historiallisen suuri 2000-luvulla, vaikka melkein puolet niistä epäonnistuu. Aineettomilla tekijöillä, kuten organisaatiokulttuureilla, on keskeinen rooli yritysostojen onnistumisissa. Myös case yritys on aktiivinen yritysostoissa ja haluaa arvioida integraatioprosessinsa tehokkuutta. Siten diplomityön tarkoituksena on luoda työkalu organisaatiokulttuurien yhteensopivuuden arvioimiseksi, jotta ostopäätöksentekoa sekä integraation suunnittelua voitaisiin tukea paremmin yrityksessä. Diplomityö vastaakin kysymyksiin, kuten miten arvioida kulttuurista yhteensopivuutta ennen integraatiota integraatioprosessin parantamiseksi sekä mitkä ovat olleet kaikkein ongelmallisimmat ja toisaalta kaikkein menestyksekkäimmät kulttuuritekijät tutkitussa integraatiossa. Kulttuurisen yhteensopivuuden arviointi tulisi nähdä prosessina osana yrityskauppaa. Prosessin tulisi alkaa kulttuurisen integraation tavoitteiden määrittämisellä sekä organisaatiokulttuurin käsitteen ymmärtämisellä. Kulttuurianalyysi tulisi suorittaa työpajan avulla. Sen tulisi käsitellä ainakin yhdeksän kulttuurin osa-aluetta: innovatiivisuus, päätöksenteko, ihmissuuntautuneisuus, kommunikaatio, kontrolli, asiakassuuntautuneisuus, ajanhallinta, identifikaatio, sekä kollektivismi. Lisäksi kuhunkin dimensioon liittyvään kysymykseen tulisi vastata pisteillä yhdestä viiteen, jolloin voidaan piirtää kulttuurisen yhteensopivuuden kuvio. Tämän jälkeen johdon tulisi keskustella tuloksista vielä kerran tarkemmin ja lopulta koota tulokset kirjalliseksi raportiksi. Tutkitussa integraatiossa parhaiten integraatiota tukivat ihmissuuntautuneisuus sekä ajanhallinta (työn ja vapaa-ajan välinen tasapaino sekä tulevaisuus-suuntautuneisuus). Haasteellisimmat kulttuuritekijät koskivat päätöksentekoa, kommunikaatiota ja kontrollia, jotka vaikuttavat olevan tyypillisiä ongelmia ison yrityksen ostaessa pienemmän yrityksen.
