U ožujku 2020. godine vrata hrvatskih muzeja zatvorena su na nekoliko tjedana kako bi se spriječilo širenje bolesti COVID-19. Razdoblje fizičke zatvorenosti dodatno se produžilo za pojedine ...zagrebačke muzeje teško stradale u potresu. Nakon otvaranja, kao i u mnogim drugim muzejima u Europi i svijetu, fizičke posjete i dalje su smanjene i muzeji bilježe drastičan pad posjetitelja te financijske gubitke. Kao odgovor na trenutnu situaciju, s ciljem nastavka ispunjavanja svoje društvene, kulturne i obrazovne funkcije, muzeji su se okrenuli internetu i društvenim mrežama kao mjestima za dijalog s korisnicima, diseminaciju sadržaja i prezentaciju događanja koja se ne mogu fizički organizirati. Mnogi muzeji posvetili su se stvaranju internetskih resursa poput digitalnih izložbi, virtualnih tura, materijala za e-učenje, internetskih konferencija te se na različite načine i na različitim platformama nastoje povezati sa svojom publikom. Cilj ovog rada bio je istražiti kako su hrvatski muzeji korištenjem digitalnih medija prilagodili svoje usluge i sadržaje novim uvjetima poslovanja. U radu su analizirane i vrednovane aktivnosti muzeja na mrežnim stranicama i društvenim mrežama u godini dana od početka pandemije. Rezultati ukazuju na kvantitativno kao i kvalitativno bogatu internetsku prisutnost muzeja, koja bi mogla značiti početak nove ere u digitalnoj komunikaciji i diseminaciji baštinskih sadržaja. Istraživanje zaključuje da je digitalizacija aktivnosti muzeja nužna za buduću održivost muzejskih funkcija te potiče daljnja razmišljanja o smjeru digitalnog pristupa kulturi i baštini.

In the 21st century, we live in what can be called a “new normal” when we view law through the prism of digital technology. Technology has greatly impacted the traditional parts of civil law, such as ...law of ownership, inheritance and contracts. Technology is bringing civil law into a new, digital environment where it is necessary to consider the specifics of that environment. The freedom of contract is the basic principle of civil law, which is mainly applied in the law of obligations, in the part concerning contracts. In contrast, adhesion contracts are contracts in which the terms are dictated by one party, while the other party can only accept or reject them – take it or leave it. In the context of adhesion contracts, it is clear that freedom of contract can be violated in certain cases. Nowadays, a large number of such contracts are concluded online. Every user of a website must agree to these contracts in order to use that website. The problem of the lack of choice of the person who agrees to the pre-announced conditions in such adhesion contracts may be more pronounced online than in classical adhesion contracts. Due to certain characteristics of such contracts, users are sometimes not even aware that by their mere behaviour they have agreed to the terms and conditions of the Internet service provider (ISP) to which the website belongs. As a result, these users do not know what they have agreed to until problems arise between them and an ISP. The behaviour of the contracting parties certainly contributes to this problem. ISPs sometimes try to turn most of the provisions of the contract in their favour and diminish their importance, while users ignore this and agree to everything that is offered to them, sometimes not even knowing that they have given their consent.
Misinformation, conspiracy theories, and negative comments on social networks affect the availability of accurate health information and attitudes toward vaccination. The aim of this paper is to ...explore the opinions and attitudes of the public, i.e. misinformation and conspiracy theories about vaccination and the vaccine against the disease caused by the COVID-19 virus on Internet portals and the social network Facebook. From November 9, 2020 to January 30, 2021, a total of 4,576 comments were analyzed, i.e. 113 posts in the topic of vaccination and vaccines categorized according to sentiment (positive, neutral, irrelevant, and negative). Among the negative comments (20,60 %), 13 main thematic categories were identified. The most represented were in the category of conspiracy theories (35,84 %) and the category of expression of distrust in the composition, effectiveness, safety, and side effects of vaccines (19,93 %), while the percentage of misinformation was 20,90 %. The results highlight the necessity of designing a timely plan and strategy of health campaigns and content for online educational materials and platforms, as well as the initiation of nationwide health education programs.
This paper presents a sociological theoretical framework for the study of self-representation in social networks. Theoretically, the paper draws on the sociological classics of E. Goffman and M. ...Castells and work from other academic fields in which self-presentation and social networks have been explored as social phenomena. The first part of the paper provides a contextual framework for the development of information technology and the growth of social network users, and offers some terminological clarifications. Then, the sociological approaches to the phenomena of social networks and self-representation are analysed within the framework of the dramaturgical approach. The spatio-temporal framework created by the emergence of the Internet is questioned, and self-representation is examined in this context. The notion of the exhibition site that defines the new form of appearance on social network platforms, the temporal status of the contemporary form of self-representation on social networks and the asynchronous character of communication implied by this self-representation are also analysed.
In this paper, authors are considering current problem of legally regulated unacceptable behavior in Croatian media space, social networks included, by focusing on hate speech. Fundamental question ...is whether hate speech presence is on the rise. Through content analysis of the entire Croatian media content, authors find an increase of unacceptable behavior and hate speech. Based on results, research is focused on detection of types of hate speech and examples of their occurrence whereas this type targets ethnicity, religion and migrants. Third research is focused on events present in media space, targeting unacceptable behavior and provide contextual frame of important events using qualitative and quantitative content analysis and NLP technologies. Research continues with development of NLP technologies for detecting, processing and analyzing media content.
Self-esteem is an evaluation of a person’s own self-worth; comprising three-dimension: physical appearance, romantic attractiveness, and the ability to form and maintain close friendships. ...Self-esteem is the perception of how people perceive their own value well as their value to others.Social networks are media that provide the opportunity to shape a picture of ourselves by creating unique profiles to show the desired image of ourselves.Individuals communicate with other people through the images they have created about these people, discovering personal details and creating insights into the lives of others. The use of social networks haves negative and positive effects.Personality and self-esteem are influential factors of communication of the individual with other people.
