The use of email as a communication and information sharing medium in large, complex, globally distributed engineering projects is widespread; yet there exists little understanding of the content of the emails exchanged and the implications of this content on the design project, design records and contracts. The importance of these issues is underlined by the fact that email records can now be required as evidence in legal disputes. It follows that the overall aim of this research is to assess the role and use of email in engineering design projects. A state-of-the-art review of literature pertaining to email is reported, along with a review of information and communication processes in engineering design projects. The primary contribution of this thesis is the creation of a content based approach for analysing the role and use of email in engineering design projects. This centres on the development and application of a coding scheme to email text, identifying what subject matter an email relates to, why it was sent, and how its content is expressed. Results are then analysed with respect to the frequencies of each code and other variables, including how coding varies between different senders and throughout the project duration. The second key contribution of this thesis is the analysis of emails and content in an engineering setting by applying the aforementioned approach to two case studies. The major case study concerned a large, complex, globally distributed, multimillion pound systems engineering project, from which 16 000 emails were obtained. It was found that emails are mainly used to transfer information but also to support management functions. Emails facilitate design work but little of this takes place explicitly in the email content. Characteristics of a project affect the subject matter or emails but have little effect on why they are sent. User roles and personal preferences also influence email use. If was found that the purposes for sending emails varied over the duration of a project; it was further determined that these changes could be used to identify project progress and design activity. Implications of the findings are identified in relation to: information management, knowledge management, project management, collaboration and email practice. Significantly, emails do contain potentially important design information and because these often support decisions made elsewhere, emails should be integrated with wider records. More consideration and training should be given to the use of project standards for email use and guidelines for composition. Changes in email use over the project duration could be a potential tool for project managers to identify design progress and possible issues in a project.

As a result of globalisation, the number of companies working globally is increasing at an unprecedented pace. Consequently, the need to communicate with people from other countries is getting bigger. In such intercultural communication, a common language must be used to interact. The language of choice is most often English, which is the business lingua franca (BELF) today. Furthermore, email has become the obvious choice of medium when interacting with foreign business associates. The present study was conducted through intensive and extensive analyses, investigating BELF emails written by 21 individuals with 14 different native languages. The data consists of 209 emails. The study follows Bjørge’s (2007) work on formality in emails written in academic settings. The aim of the study was to determine how formal the participants were in greetings and closings and whether they accommodated their language to the respondent. The results suggest that the level of formality mainly depends on the purpose of the email and, to some extent, how formal the correspondent is. The accommodation to the correspondent seems to be individual. The present study wishes to extend knowledge on email communication in BELF settings. The results are likely to be relevant for teachers and students of Business Communication and English as a Second or Foreign Language along with managers in internationally functioning companies, especially as regards what should be considered in BELF communication.

(in English): This diploma thesis focuses on the topic of suicidal thoughts of juveniles and maps the possibilities that adolescents have in such a situation. The thesis is based on the knowledge of the specialized literature in the theoretical part, this section describes concepts such as crisis and crisis intervention Crisis intervention is devided into forms of contact that a juvenile can use. It also describes suicide with an emphasis on juvenile suicide. The practical part, based on research, maps the situation in the Czech Republic in the area of services for juveniles in a crisis situation who have suicidal thoughts. And whether the awareness in this area is sufficient.

E-post är det vanligaste kommunikationsverktyget för att skicka och ta emot information på arbetet. Trots dess fördelar att snabbt och enkelt kunna utbyta information visar forskning att mängden e-postmeddelanden har ökat till den grad att det bidrar till informationsöverbelastning. E-postkommunikation förväntas utsätta individer, och särskilt chefer, för allt högre nivåer av informationsöverbelastning. Forskning visar att problemet inte handlar om hur chefer ska undvika information, utan om hur chefer kan hantera e-postkommunikation. Detta leder fram till studiens frågeställning: Hur upplever chefer informationsöverbelastning vid e-postkommunikation och vilka copingstrategier använder de? För att få en ökad förståelse för hur chefer hanterar informationsöverbelastning vid e-postkommunikation har vi använt en kvalitativ forskningsansats. Med hjälp av en tematisk analys har vi kunnat identifiera, analysera och upptäcka återkommande mönster av chefers upplevelse. Vi valde därefter att skapa teman av hur upplevelser kan förstås för att kunna beskriva vilka upplevelser som copingstrategier baseras på. De teman som vi har identifierat under den tematiska analysen är: mängd, alltid ansluten, avbrott och organisationsstöd. Tillsammans skapar de fyra temana en förståelse för hur chefer kan uppleva informationsöverbelastning vid e-postkommunikation och vilka copingstrategier de använder. Studien indikerar att det finns kontraster i chefers upplevelser. En upplevelse som kan upplevas som överbelastande för en chef behöver inte vara det för en annan chef. Detta pekar på att det inte finns en enskild copingstrategi för att hantera informationsöverbelastning vid e-postkommunikation. / Email is the most common communication tool for sending and receiving information at work. Despite emails advantages of being able to exchange information quickly and easily, research shows that the volume of emails has increased to the extent that it contributes to information overload. Email communication is expected to expose individuals, and especially managers, for even higher levels of information overload. Research shows that the problem is not about how managers could avoid information, but about how managers can handle email communication. This leads to the question: How do managers experience information overload within email communication and what coping strategies do they use? In order to gain an increased understanding of how managers handle information overload within email communication, we have used a qualitative research approach. With the use of a thematic analysis, we have been able to identify, analyze and detect recurring patterns of managers’ experiences. We then chose to create themes of how experiences can be understood to describe what experiences coping strategies are based on. The themes that we identified under the thematic analysis are: amount, always connected, interruption and organizational support. Together, the four themes create an understanding of how managers can experience information overload within email communication and that coping strategies they use. The study indicates that there are contrasts in managers experiences. An experience that one manager can perceive as overloading does not have to be overloading for another manager. This demonstrates that there is no single coping strategy for managing information overload within email communication.

Communication with the customer plays a crucial role in today's internet marketing. In case we do not communicate with the customer or we let his attention towards our product or service fade away, than the investment into gaining him has not been well used. Email marketing itself is a very good instrument for maintaining and building the relationship with the customer. However, a great number of entrepreneurs and companies does not know how to work with email marketing and they send email just the same way as they would invite their colleagues for a meeting or simply just scan a discount flier. The first part of the master thesis therefore focuses on the definition of email marketing itself and of the features by which emails affect the customers. It than presents the ways how to maintain the customer, how to pamper them by e.g. content marketing and it shows the current trends and possibilities of automatization. The second part of the master thesis than presents and uses email marketing not only as one of the very strong instruments of direct marketing but also as one of the ways to support online education, which has been gaining a lot of popularity both in the Czech Republic and abroad. The thesis shows the possibilities how to use email marketing to promote an education website that is being created concurrently with this thesis and how to teach its visitors. The practical part shows how to set up the path of the customer and the email marketing strategy in order to change the visitors of the website into loyal customers. All that with the highest possible automatization of the process.

In the modern world, email communication defines itself as the most used technology for exchanging messages between users. It is based on three pillars which contribute to the popularity and stimulate its rapid growth. These pillars are represented by free availability, efficiency and intuitiveness during exchange of information. All of them constitute a significant advantage in the provision of communication services. On the other hand, the growing popularity of email technologies poses considerable security risks and transforms them into an universal tool for spreading unsolicited content. Potential attacks may be aimed at either a specific endpoints or whole computer infrastructures. Despite achieving high accuracy during spam filtering, traditional techniques do not often catch up to rapid growth and evolution of spam techniques. These approaches are affected by overfitting issues, converging into a poor local minimum, inefficiency in highdimensional data processing and have long-term maintainability issues. One of the main goals of this master's thesis is to develop and train deep neural networks using the latest machine learning techniques for successfully solving text-based spam classification problem belonging to the Natural Language Processing (NLP) domain. From a theoretical point of view, the master's thesis is focused on the e-mail communication area with an emphasis on spam filtering. Next parts of the thesis bring attention to the domain of machine learning and artificial neural networks, discuss principles of their operations and basic properties. The theoretical part also covers possible ways of applying described techniques to the area of text analysis and solving NLP. One of the key aspects of the study lies in a detailed comparison of current machine learning methods, their specifics and accuracy when applied to spam filtering. At the beginning of the practical part, focus will be placed on the e-mail dataset processing. This phase was divided into five stages with the motivation of maintaining key features of the raw data and increasing the final quality of the dataset. The created dataset was used for training, testing and validation of types of the chosen deep neural networks. Selected models ULMFiT, BERT and XLNet have been successfully implemented. The master's thesis includes a description of the final data adaptation, neural networks learning process, their testing and validation. In the end of the work, the implemented models are compared using a confusion matrix and possible improvements and concise conclusion are also outlined.
