In the thesis we are going to focus on the topic of on-line political communication of 8 czech ballot leaders on the social network service Facebook during the 2019 European Parliament election campaign. On-line campaign is essential tool to gain the favor of the electorate in the 4th age of political communication. In long term perspective the European Parliament elections are suffering from the low interest of the electorate and from the trend of decreasing tournout in both pan-European and Czech political arenas. Our research is based on the theoretical concepts about main functions of on-line campaign in the 4th age of political communication. The mobilization of the electorate towards political participation is one of those functions. Next we base our research on the second order elections theory of Karlheinz Reif and Hermann Schmitt. The European Parliament elections are characterised by predominance of topics important to the local political system and by substituting as a referendum about the government of a member country. Last but not least, we base our research on the theory of Paul Taggart and Alexander Szczerbiak, who say that today, euroscepticism is an attractive mainstream topic, which can be found throughout the whole political spectrum. The goal of our research is to prove and...

This study set out to establish an informed framework for the use of social network services in South African museums. Social network services are utilised by a wide demographic spectrum so they offer a cost-effective way to engage with communities and with existing and new stakeholders. The Standard of Generally Recognised Accounting Practice on Heritage Assets, or GRAP 103, and the draft National Policy on Digitisation of Heritage Resources imply that museum collections get documented and managed in digital form. It will coincidentally also enable museums to embrace the use of social network services and share the collections in their custody with many South Africans who are yet to experience the value of museums in the country. Museums are institutions in the service of society which acquires, conserves and communicates the tangible and intangible heritage of people and their environment. During the twentieth century museums have had to reinvent themselves from being unapproachable custodians of heritage to being part of society, willing to engage in discourses and be transformed to remain relevant to the communities they serve. The 2011 Census has found that about 18.2 million of 51.7 million South Africans have had access to the Internet before. Active Internet users however, are about half that figure because it is expensive, the broadband and telecommunications network is not efficient or because people have not yet experienced the value it offers. Government regulations compel Information and Communication Technology (ICT) enterprises to spend 1.5% net profit after tax on socio economic development initiatives. This presents an opportunity for museums as educational institutions to engage with such enterprises to expand Internet access and engage with local communities. The social network service field offers various ways to communicate collections and engage with communities through text, photographs, video and location-based technologies. Various notable local and international initiatives were discussed in this study. For example the Kulturpool which allows visitors to create cyber collections from digitised museum objects and contribute to the knowledge of such objects by allowing them to submit and share information for others to read. SAHRIS, the digital database offered by the South African Heritage Resources Agency, holds the key to similar ventures that museums could pursue. The regulative framework involves privacy, copyright and ethical issues which museums should abide by. Because of the pervasiveness of ICTs museums should take note of these regulations even if they decide not to pursue social network initiatives. ICT skills in museums are insufficient and should be improved upon. Social network services offer training and guidelines on how to use them, which could be a great help provided the reader has a good command of the English language. Cognisance must be taken of an overview social network services and their uses, and of the ethical and regulative framework for museums to benefit from using social network services to engage with communities. This way, communities may benefit from having access to the museum online. / Dissertation (MHCS)--University of Pretoria, 2014. / gm2014 / Historical and Heritage Studies / unrestricted

Récemment, l'intégration entre les environnements informatiques et de réseautage a été largement promu pour fournir des services intelligents à des utilisateurs finaux ainsi que l'utilisation efficace des ressources. Cette convergence a ouvert la voie à l'émergence de l'internet des objets (IdO). Le paradigme de l'IdO repose principalement sur la fabrication d'objets, appelés les choses, disparaître et se tissent dans le tissu de notre vie de tous les jours pour nous soutenir dans l'accomplissement des activités quotidiennes. L'évolutivité et l'hétérogénéité sont parmi les principaux défis qui entravent la réalisation à grande échelle de services de l'IdO dans la vie quotidienne des utilisateurs. Afin de relever les défis de l'IdO, un nouveau volet de recherche est venu en avant dans la littérature comme une classe paradigmatique des Cyber-physiques systèmes sociaux (CSPR), qui est connu comme l'Internet social des choses (Siot). Le SIOT se fonde sur la notion soulignée par phénomène petite-monde où la structure sociale permettant relation sociale fondée sur la confiance entre les personnes et les objets, d'une manière qui ressemble à des services de réseaux sociaux traditionnels (SNS) est suggérée de relever les défis de l'IdO. Cependant, depuis SIOT hérite des caractéristiques de différents informatiques et de réseautage environnements (par exemple, l'IdO et SNS) cela, en fait, augmente la quantité et la variété des données contextuelles qui doit être manipulé pour Adaptive fourniture de services dans Siot, qui agit comme le principal défi adressé dans cette thèse. Autrement dit, dans cette thèse, nous proposons la notion de contexte cognitif lorsque, dans certaine situation spatio-temporelle, le raisonnement sur les aspects objectifs du cadre, ce qui représente l'environnement physique, avec le contexte subjective, qui représente les aspects comportementaux et sociaux, est considéré comme l'amélioration des services SIOT intelligence et la capacité d'adaptation aux besoins conjoncturels des utilisateurs. Nous envisageons technologies du Web sémantique pour déployer notre contexte cognitif proposé dans deux domaines d'application; sensible au contexte recommandation des tâches quotidiennes dans les maisons intelligentes et structure sociale dépendant de la situation des choses. Un prototype de preuve de concept a été développé pour chaque domaine d'application, dans le but de démontrer l'intégration harmonieuse des objets sur le Web pour la réalisation de certaines applications. Nos résultats empiriques montrent un niveau de service amélioré l'adaptabilité et la complexité en temps de fonctionner lors de l'application de notre contexte cognitif suggéré / The paradigm of the Social Internet of Things (SIoT) is being promoted in the literature to boost a new trend wherein the benefits of social network services are exhibited within the network of connected objects i.e., the Internet of Things (IoT). The novel user-friendly interaction framework of the SIoT opens the doors for enhancing the intelligence required to stimulate a shift in the IoT from a heterogeneous network of independently connected objects towards a manageable network of everything. In practice, achieving scalability within the large-scale and the heterogeneous paradigm of the IoT while maintaining on top of its user-friendly and intuitive services to bridge human-to-machine perceptions and encourage the technology’s adaptation is a major challenge which is hindering the realization and deployment of the IoT technologies and applications into people’s daily live. For the goal of handling IoT challenges, as well as improve the level of smart services adaptability to users’ situational needs, in this thesis, novel SIoT-based application architecture is provided. That is, Semantic Web Technologies are envisaged as a means to develop automated, value-added services for SIoT. While, interoperability and automation are essential requirement to seamlessly integrate such services into user life, Ontologies are used to semantically describe Web services with the aim of enabling the automatic invocation and composition of these services as well as support interactions across the cyber, physical and social worlds. On the other hand, handling the variety of contextual data in SIoT for intelligent decision making is another big challenge which is still in very early stages of research. In this thesis we propose a cognitive reasoning approach taking into consideration achieving situational-awareness (SA) in SIoT. This reasoning approach is deployed within two application domains where results show an improved level of services adaptability compared to location-aware services which are previously proposed in the literature
