M��tamorphoses identitaires en situation de mobilit��

<b>Identity metamorphoses in a context of mobility</b> This study has its roots in the current upsurge in student mobility and in the scientific debates about the concepts of identity and intercultural communication. Based on a corpus of interviews with French Erasmus students in Finland, the study blends in theories of postmodern identity, intercultural hermeneutics and discourse analysis to examine how the students construct themselves and diverse ���othernesses��� (included theirs) when they talk about their experiences. The use of the French pronoun on, pronoun switches, and virtual voices (ex: I said to myself...) allowed to pinpoint the students��� unstable identity metamorphoses in their discourses: integration of liquid and solid selves, infidelity in identification with the French but also with Erasmus ���tribes���, and games of identity. Though the exchange experience appears as interesting for the students, the results show that many and varied misconceptions about identity, culture, intercultural communication, language use, and strangeness lead the students to evaluate their experiences negatively. The implication of the study is that students should be prepared for their time abroad, not so much in terms of ���grammars of culture��� (e.g. ���Finns behave in such and such ways���, ���the French are...���), but through the development of competences to analyse the identity metamorphoses that take place in intercultural encounters and prevent people from meeting each other as diverse individuals. This could make study abroad one of the best training periods for postmodernity and globalization.

Communication challenges in virtual teams ��� a case study of implementing computer-mediated communication technologies in inter-organisational virtual teams

This thesis seeks to answer, if communication challenges in virtual teams can be overcome with the help of computer-mediated communication. Virtual teams are becoming more common work method in many global companies. In order for virtual teams to reach their maximum potential, effective asynchronous and synchronous methods for communication are needed. The thesis covers communication in virtual teams, as well as leadership and trust building in virtual environments with the help of CMC. First, the communication challenges in virtual teams are identified by using a framework of knowledge sharing barriers in virtual teams by Rosen et al. (2007) Secondly, the leadership and trust in virtual teams are defined in the context of CMC. The performance of virtual teams is evaluated in the case study by exploiting these three dimensions. With the help of a case study of two virtual teams, the practical issues related to selecting and implementing communication technologies as well as overcoming knowledge sharing barriers is being discussed. The case studies involve a complex inter-organisational setting, where four companies are working together in order to maintain a new IT system. The communication difficulties are related to inadequate communication technologies, lack of trust and the undefined relationships of the stakeholders and the team members. As a result, it is suggested that communication technologies are needed in order to improve the virtual team performance, but are not however solely capable of solving the communication challenges in virtual teams. In addition, suitable leadership and trust between team members are required in order to improve the knowledge sharing and communication in virtual teams.

Customer-Related Internal Communication in a Global Matrix Organization

The objective of the thesis was to explore the nature and characteristics of customer-related internal communication in a global industrial matrix organization during a specific customer relationship, and how it could be improved. The theoretical part of the study views the field of the concepts of intra-organizational information and knowledge sharing. The theoretical part also views the internal communications influences to customer relationships, its problematic, and the suggestions to improve internal communication in literature. The empirical part of the study was conducted with the Content Analysis and the Social Network Analysis as research methods. The data was collected by interviews and a questionnaire. Internal communication was observed first generally within the organization from the point of view of a certain business, and secondly, during a specific customer relationship at personal level and at departmental level. The results of the study describe the nature and characteristics of internal communication in the organization. The results give 13 suggestions for improving internal communication in the organization. Although the study has been done in one specific organization, it also offers insights for other organizations as well as managers to improve their internal communication.

Power line communication in motor cables of variable-speed electric drives ��� analysis and

Data transmission between an electric motor and a frequency converter is required in variablespeed electric drives because of sensors installed at the motor. Sensor information can be used for various useful applications to improve the system reliability and its properties. Traditionally, the communication medium is implemented by an additional cabling. However, the costs of the traditional method may be an obstacle to the wider application of data transmission between a motor and a frequency converter. In any case, a power cable is always installed between a motor and a frequency converter for power supply, and hence it may be applied as a communication medium for sensor level data. This thesis considers power line communication (PLC) in inverter-fed motor power cables. The motor cable is studied as a communication channel in the frequency band of 100 kHz���30 MHz. The communication channel and noise characteristics are described. All the individual components included in a variable-speed electric drive are presented in detail. A channel model is developed, and it is verified by measurements. A theoretical channel information capacity analysis is carried out to estimate the opportunities of a communication medium. Suitable communication and forward error correction (FEC) methods are suggested. A general method to implement a broadband and Ethernet-based communication medium between a motor and a frequency converter is proposed. A coupling interface is also developed that allows to install the communication device safely to a three-phase inverter-fed motor power cable. Practical tests are carried out, and the results are analyzed. Possible applications for the proposed method are presented. A speed feedback motor control application is verified in detail by simulations and laboratory tests because of restrictions for the delay in the feedback loop caused by PLC. Other possible applications are discussed at a more general level.

Older consumers adopting information and communication technology: Evaluating opportunities for health care applications

The purpose of this dissertation is to analyse older consumers' adoption of information and communication technology innovations, assess the effect of aging related characteristic, and evaluate older consumers' willingness to apply these technologies in health care services. This topic is considered important, because the population in Finland (as in other welfare states) is aging and thus offers a possibility for marketers, but on the other hand threatens society with increasing costs for healthcare. Innovation adoption has been under research from several aspects in both organizational and consumer research. In the consumer behaviour, several theories have been developed to predict consumer responses to innovation. The present dissertation carefully reviews previous research and takes a closer look at the theory of planned behaviour, technology acceptance model and diffusion of innovations perspective. It is here suggested that there is a possibility that these theories can be combined and complemented to predict the adoption of ICT innovations among aging consumers, taking the aging related personal characteristics into account. In fact, there are very few studies that have concentrated on aging consumers in the innovation research, and thus there was a clear indent for the present research. ICT in the health care context has been studied mainly from the organizational point of view. If the technology is thus applied for the communication between the individual end-user and service provider, the end-user cannot be shrugged off. The present dissertation uses empirical evidence from a survey targeted to 55-79 year old people from one city in Southern-Carelia. The empirical analysis of the research model was mainly based on structural equation modelling that has been found very useful on estimating causal relationships. The tested models were targeted to predict the adoption stage of personal computers and mobile phones, and the adoption intention of future health services that apply these devices for communication. The present dissertation succeeded in modelling the adoption behaviour of mobile phones and PCs as well as adoption intentions of future services. Perceived health status and three components behind it (depression, functional ability, and cognitive ability) were found to influence perception of technology anxiety. Better health leads to less anxiety. The effect of age was assessed as a control variable, in order to evaluate its effect compared to health characteristics. Age influenced technology perceptions, but to lesser extent compared to health. The analyses suggest that the major determinant for current technology adoption is perceived behavioural control, and additionally technology anxiety that indirectly inhibit adoption through perceived control. When focusing on future service intentions, the key issue is perceived usefulness that needs to be highlighted when new services are launched. Besides usefulness, the perception of online service reliability is important and affects the intentions indirectly. To conclude older consumers' adoption behaviour is influenced by health status and age, but also by the perceptions of anxiety and behavioural control. On the other hand, launching new types of health services for aging consumers is possible after the service is perceived reliable and useful.

���That you too were the I���: Forms of polyphonic communication in John Ashbery���s poetry

Tarkastelen tutkimuksessani amerikkalaisen John Ashberyn (1927���) runoudessa lmenev���� moni����nisyytt��. Runoutta pidet����n yleens�� yksi����nisen�� puheena, kun taas omaanin ajatellaan erityisesti Mihail Bahtinin vaikutuksesta olevan luonnostaan oni����ninen kirjallisuudenlaji. Ashberyn postmoderni runous haastaa t��m��n ��sityksen. Ashbery tunnetaan vakiintuneita runousk��sityksi�� vastaan kirjoittavana avantgarde-runoilijana. P����asiallisina tutkimuskohteinani ovat Ashberyn pitk�� runoelma nimelt�� ���Litany��� (1979) sek�� lyhyiden runojen valikoima <i>Your Name Here</i> (2000). Vertailukohtana tarkastelen Ashberyn yhdess�� James Schuylerin kanssa kirjoittamaa romaania <i>A Nest of Ninnies</i> (1969). Teoreettisena pohjana on k��ytetty Ashbery�� k��sittelev��n muun tutkimuksen lis��ksi muun muassa j��lkistrukturalistisiin teorioihin liittyvi�� ajatuksia pronominien vaikutuksesta siihen miten lukija muodostaa k��sityksen subjektiivisesta l��sn��olosta runossa. Ashbery k��ytt���� persoonapronomineja ilman selkeit�� viittaussuhteita. Viittaussuhteiden h��m��rtymisen ja fragmentaarisuuden vuoksi Ashberyn runoja pidet����n usein vaikeina, eik�� niist�� ole helppo l��yt���� yht�� selke���� aihetta. Hajanaisuus on kuitenkin motivoitua, koska juuri se mahdollistaa moni����nisyyden ja avoimen tekstin, joka voi sis��lt���� monia merkityksi��. Kun runossa ei ole yhden puhujan hallitsevaa ����nt��, lukijan rooli merkitysten muodostajana nousee keskeiseksi. ���Litany��� on selke��sti metatekstuaalinen runo, jossa fiktiivinen taso sekoittuu runouden, taiteen ja kritiikin mahdollisuuksien pohdintaan. Runo hahmottelee uudenlaista, moni����nist�� teorian ja runouden rajoja purkavaa kommunikaation muotoa. Toisen persoonan pronominien voidaan runossa usein ajatella puhuttelevan lukijaa. <i>Your Name Here</i> -kokoelmassa puolestaan toisen persoonan pronominipositiot m����rittyv��t usein tietyiksi henkil��hahmoiksi runojen maailmassa, ja pronominipositioiden kautta runoissa rakentuu moni����nisi�� dialogeja m����rittym��tt��mien henkil��hahmojen v��lille. N��in lukijan huomio suunnataan ensisijaisesti kommunikaation ja arkip��iv��n kielenk��yt��n kliseiden s��vyihin ja asiayhteyksiin pikemminkin kuin yksitt��isten lausumien sis��lt����n. <i>A Nest of Ninnies </i>-romaani toimii n��enn��isest�� dialogisuudestaan huolimatta ennen kaikkea yksi����nisesti, sill�� romaanin yksiulotteisten henkil��hahmojen esitt��mi�� ajatuksia hallitsee parodioimaan pyrkiv�� kertojan����ni. Ashberyn runojen ja romaanin tarkasteleminen osoittaa, ett�� k��sitys runoudesta v��ist��m��tt�� yksi����nisen�� ja romaanista moni����nisen�� ei ole kaikilta osin ongelmaton. Moni����ninen, monimerkityksinen runo voi tarjota toiselle itsen��isen aseman.

TransPromo communication as a part of company���s marketing communications when the e-bill is a medium

The goal of this thesis was to research what TransPromo is, why companies want to implement TransPromo communication, and what the elements of effective Transpromo communication are. Furthermore, the goal was to develop a TransPromo communication strategy and a normative model for TeliaSonera Finland, which depicts the elements of effective TransPromo communication when the electronic bill is a medium. Abductive reasoning was utilized in this thesis, which means that empirical and theoretical worlds are alternating in researcher���s reasoning process. This thesis didn���t rely on any specific theory nor did it utilize any previous theoretical model. However, certain theoretical connections existed so this thesis cannot be considered purely inductive. The empirical part of this thesis was conducted by examining secondary industry data and by conducting specialist interviews at TeliaSonera Finland and Str��lfors. Grounded Theory approach was utilized in the analysis of the interview data and content analysis was used in the analysis of secondary industry data. This thesis increases knowledge in the area of TransPromo communication, and provides one definition of TransPromo communication. As a result of this thesis, a TransPromo communication strategy and a normative model for TeliaSonera Finland was built. The model depicts the elements of the effective TransPromo communication when the e-bill is a medium. The TranPromo communication objective is to utilize transaction documents, such as bills, in order to deliver targeted and personalized marketing messages to current customers. The aim is to strengthen the customer relationship, and to enforce up-sell and cross-sell opportunities and cost savings.

Visualization of communication system testing logs

During the past decades testing has matured from ad-hoc activity into being an integral part of the development process. The benefits of testing are obvious for modern communication systems, which operate in heterogeneous environments amongst devices from various manufacturers. The increased demand for testing also creates demand for tools and technologies that support and automate testing activities. This thesis discusses applicability of visualization techniques in the result analysis part of the testing process. Particularly, the primary focus of this work is visualization of test execution logs produced by a TTCN-3 test system. TTCN-3 is an internationally standardized test specification and implementation language. The TTCN-3 standard suite includes specification of a test logging interface and a graphical presentation format, but no immediate relationship between them. This thesis presents a technique for mapping the log events to the graphical presentation format along with a concrete implementation, which is integrated with the Eclipse Platform and the OpenTTCN Tester toolchain. Results of this work indicate that for majority of the log events, a visual representation may be derived from the TTCN-3 standard suite. The remaining events were analysed and three categories relevant in either log analysis or implementation of the visualization tool were identified: events indicating insertion of something into the incoming queue of a port, events indicating a mismatch and events describing the control flow during the execution. Applicability of the results is limited into the domain of TTCN-3, but the developed mapping and the implementation may be utilized with any TTCN-3 tool that is able to produce the execution log in the standardized XML format.

Utilizing Near Field Communication in Health Care

In this master���s thesis, possibilities to utilize Near Field Communication (NFC) technology in health care applications are examined. NFC is a short-range wireless communication technology that enables the exchange of data between devices. Main components in NFC are tag, which contains data, a NFC reader device, which can be for instance embedded to mobile phone and also act as a tag, and an antennae in both tag and reader. In this work NFC technology is discussed and its utilization in health care information systems that are in use or in trial. Utilization of information technology in health care field is examined superficially. In this thesis, a system utilizing NFC is designed and its requirements and architecture presented. NFC is used in identification of care worker. When care worker arrives at the house of a patient, she brings the NFC-enabled mobile phone near NFC tag. This sends information to the application server. This information contains the time of arrival and patient and location identifier. When care worker leaves the place, she repeats the procedure. Information gathered can be used in reporting and real time tracking.

The relationship between a virtual leader���s communication practices and a virtual team���s performance

A lot of research has been carried out into virtual teams and virtual leadership, yet there is hardly any research available on the communication behaviour of virtual leaders within a real business context. This research assessed the communication practices of virtual leaders and analysed the relationship between these practices and the performance of virtual teams. The objective of this research was to examine the distinctions of virtual teams, to study the leader���s role in a virtual team and its performance, and to examine the leader���s communication practices within virtual teams. The research involves a case study in which interviews have been carried out within an international technology company headquartered in Finland. Qualitative research methods were applied in the research. Based on the results of the study it can be said that there is a strong relationship between a virtual leader���s communication practices and a virtual team member���s job satisfaction. Through their communication practices, activities and message contents, leaders can affect the job satisfaction of virtual team members. In virtual leadership the focus is not in virtual but in leadership. It does not matter if the context is virtual or face-to-face; similar communication practices are good in both cases. As the global economic crisis strongly affected the sales results of the between a leader���s communication practices and a virtual team���s objective performance cannot be made.

A Communication Middleware Quality Enhancement with Qt Framework

In this thesis, a Peer-to-Peer communication middleware for mobile environment is developed using the Qt framework and the Qt Mobility extension. The Peer-to-Peer middleware ��� called as PeerHood ��� is for service sharing in network neighborhood. In addition, the PeerHood enables service connectivity and device monitoring functionalities. The concept of the PeerHood is already available in native C++ implementation on Linux platform using services from the platform. In this work, the PeerHood concept is remade to be based on use of the Qt framework. The objective of the new solution is to increase PeerHood quality with using functionalities from the Qt framework and the Qt Mobility extension. Furthermore, by using the Qt framework, the PeerHood middleware can be implemented to be portable cross-platform middleware. The quality of the new PeerHood implementation is evaluated with defined quality factors and compared with the existing PeerHood. Reliability, CPU usage, memory usage and static code analysis metrics are used in evaluation. The new PeerHood is shown to be more reliable and flexible that the existing one.

Carbon footprint as part of a company���s external environmental communication

The aim of this thesis was to find out how the carbon footprint calculations can be utilized in the company���s external environmental communication, what is the demand for carbon footprint from the market, and how the other actors in the forest industry have approached the issue. The aim was to recognize the best practises to communicate carbon footprints and to find possibilities to extend the UPM-Kymmene Wood Oy���s mill specific carbon footprints. This research included a literature review, an inquiry to the UPM-Kymmene Wood Oy���s sales offices, and Internet survey concerning the external environmental communication in the forest industry and three small case studies based on mill specific parameters. The inquiry to the sales offices showed that the carbon footprint is not yet a common demand from the customers in the wood product sector. In addition, the Internet survey showed that generally in the forest industry, not much has been done concerning carbon footprint communication so far. The biggest challenge in carbon footprint communication is the variation in the knowledge level of the receivers. In addition btob and btoc communication situations demand a different approach to the issue. Carbon profile brochures developed in the company can be seen as suitable for btob communication situations. Case studies have shown that the contribution of final product transport to the overall carbon footprint was significant. It was recommended to include post mill transport in the carbon footprint information supplied to the btob customers. When discussing environmental communication on a general level it can be stated that a good external environmental communication is based on facts, is open and proactive and takes into account the needs of the receiver. However, the openness and the quality of external environmental communication are essentially strategic decisions. The significance of internal communication as well as the knowhow in the communication and marketing networks play a major role in achieving success in external environmental communication. Carbon footprints are only one part of good balanced external environmental communication. One specific environmental feature like carbon footprint should not be over emphasized to the detriment of other important environmental aspects.
