(in English): The thesis deals with online labour markets. They are differentiated against job portals and have their characteristics and specific variations relevant to workers and employers analysed. The thesis also differentiates a Talent Market. The analysis identifies geographical distribution of workers as well as the workforce composition related to primary area of expertise. A significant borderline between the dominant fields of work in the east and west is found. The analysis also focuses on fees imposed by individual portals and their relation to the utility of a given portal. In the conclusion, recommendations concerning choosing the most suitable market with regard to the nature and length of the project are given.

ABSTRACT This study empirically evaluates the theoretical impact of a telecommuting or online work environment on employee loyalty. While the concept of employee loyalty has been extensively researched, the concept of the impact of the work environment on employee loyalty is fairly new. Specifically, this study operationally defines the work environment characteristics that contribute to employee loyalty and examines the impact of the online or telecommuting work environment on employee loyalty. A survey instrument is utilized to collect perceptual data about the psychological components of the work environment and their impact on employee loyalty from the employee's perspective. Multiple linear regression analysis is used to analyze the data from one hundred and three respondents to determine correlation between the work environment characteristics and employee loyalty. Additional statistics utilized in the analysis of the data include: factor analysis, t-test, K-S test, and Cronbach's Alpha. While the study's findings confirm that the three work environment factors (job satisfaction, social interaction, and trust) contribute to employee loyalty as represented by the surrogate, intent to turnover, the dynamics underlying the perceptions of telecommuting and traditional collocated employees is complex. Telecommuting employees, as hypothesized, demonstrate higher levels of intention to turnover, the key construct in the study, than do traditional onsite employees. Similarly, job satisfaction is much lower for telecommuters. No statistically significant differences were found in trust or social interaction. When exploring casual impacts of satisfaction, social interaction and trust on intention to turnover, very different dynamics emerged between the telecommuting and traditional. In particular, job satisfaction, while very important to the traditional workers, was insignificant to intention to turnover to telecommuter employees. In addition, telecommuters apparently had derived alternative mechanisms to allow for social interactions, other than face-to-face ones. Trust, in both groups, is an overriding factor in ameliorating intention to turnover. This research adds to current perspectives on the effects of the work environment on employee loyalty. This research will enhance insights into this increasingly prevalent work environment, and organization researchers and managers will be able to use these results to enhance understanding of the impact on work environment. These contributions may help to decrease turnover and enhance the satisfaction derived in telecommuting work environments. The study ends with a discussion of limitations and suggestions for future research.

This diploma thesis addresses use of cloud computing and collaborative presentation tools in ICT education in schools. It also devotes to representative applications and their evaluation and indetifies key questions which help to chose suitable application to education. Questionnaire survey evaluates application among students and proposes activities that are effective with use of these tools. This work tracks activity of students with collaborative tools and evaluates their engagement in education. Action research watches students and their work in order to evaluate engagement in education process.

Due to the COVID-19 pandemic, the world faced lockdown and quarantine restrictions that encouraged or forced people to stay home. Along with the rest of the world, Brazil faced many difficulties during this period and it became one of the countries that lost more lives due to the Coronavirus infection worldwide. This study focuses on showing how people in Brazil coped with the challenges brought by the pandemic. It also focuses on showing if and how participants used media as a coping mechanism. The research was done through qualitative methods with semi-structured interviews with 25 adults who were living in Brazil during the pandemic and the lockdown restrictions. This study shows that participants did use media as a coping mechanism and even though they have encountered negative consequences, they have also faced and mentioned several positive effects during this period. Participants mentioned other coping mechanisms that made a difference for them during the darkest moments in the pandemic like, having interpersonal communication with family and friends, religion, gaming, and others.

The aim of this study was to examine school counselors' experience working with high school students' psychosocial health during spring 2020 when school was online. The empirical data consists of qualitative interviews with nine school counselors. The result showed that school counselors used their discretion at a greater extent to help and support their students during spring 2020. They also said that the online communication made it easier for some students to contact the counselors. The school counselors said that there were some students that dislike the online way of communicating and in these cases the school counselors made other arrangements for them. Furthermore, the school counselors could see that virtual learning had an impact on the students psychosocial health mainly due to the lack of everyday routines and social contact with other students. The results of the interviews were analyzed using the theoretical concept of discretion and the professional meeting. The conclusion states that school counselors need to incorporate digital communication in their everyday work even when school is not online to be able to meet the needs of every student. It also shows the great impact school has on students' psychosocial health.
