Η έννοια της γωνίας αποτελεί μια βασική έννοια που συντελεί σημαντικά στην ανάπτυξη της γεωμετρικής γνώσης των μαθητών. Παράλληλα η μετρησή της γωνίας είναι αναπόσπαστο κομμάτι των μαθηματικών, των θετικών επιστημών και της τεχνολογίας αλλά και της καθημερινής ζωής . Έρευνες έχουν δείξει ότι οι μαθητές αντιμετωπίζουν πολύ συχνά δυσκολίες με την έννοια και την μέτρηση της γωνίας κυριώς από το γεγονός ότι η έννοια της είναι αφηρημένη και πολύπλευρη ανάλογα με κάθε τάξη. Ετσι συχνά οι μαθητές αντιμετωπίζουν δυσκολίες και καταλήγουν σε παρανοήσεις κατά την εκμάθηση των εννοιών της και την απόκτηση των αντίστοιχων δεξιοτήτων. / The concept of angle is a key concept that contributes significantly to the development of geometric knowledge of students. Similarly, the angle measurement is an integral part of mathematics, science and technology and daily life. Studies have shown that students often face difficulties with the concept and measurement of angle predominantly by the fact that the concept is abstract and multifaceted depending on each class. So often students face difficulties and lead to misunderstandings when learning the concepts and the acquisition of the relevant skills

The traditional news media is being reshaped by the phenomenon known as media convergence. This thesis, which is presented as a journalistic, multimedia website (see http://www.artsweb.aut.ac.nz/mediaconvergence), explores media convergence in New Zealand. Its primary objective is to gauge the impact of convergence on the extent to which journalism fulfils its public interest duties. To this end, the defining elements of convergence are examined, along with its driving factors and impact on day-to-day newsroom practices. The research project is based on in-depth interviews with news media experts and practitioners and the results of an industry survey. The research findings indicate that convergence poses significant risks to public interest journalism. At present, however, there is more evidence of benefits than detriments.

Esta dissertação tem por objetivos revisar alguns estudos quantitativos de transbordamentos de conhecimento e testar suas ferramentas num aglomerado brasileiro. Estes métodos são amplamente utilizados na literatura internacional e, após esta revisão, foi executada uma pesquisa no Sistema Local de Produção (SLP) de Tecnologia da Informação e Comunicação (TIC) de Campinas. A discussão sobre as características, qualidades e limitações destes cinco tipos de estudos (função produção de conhecimento, citação de patentes, mobilidade de trabalhadores qualificados, comércio de novos produtos e contatos informais) levou a opção de aplicar uma pesquisa baseada principalmente no método dos contatos informais e, de modo exploratório, numa variante da citação de patentes que usa as citações de artigos científicos como indicador primordial. O questionário foi respondido por profissionais da região que atuam em atividades de TIC. Entre os resultados da pesquisa alguns se sobressaem. Primeiro, há uma expressiva presença de transbordamentos de conhecimento na região de Campinas e esta é uma importante forma de obtenção de conhecimento por parte dos funcionários das empresas do ramo de TIC. Segundo, os funcionários com maiores capacitações e com maior experiência no setor tendem a obter conhecimento mais valioso de seus colegas. Terceiro, os funcionários de empresas multinacionais obtém menos conhecimento de seus contatos informais, pois têm acesso a outros meios para resolução de problemas dentro da própria firma, enquanto isso, os funcionários de empresas brasileiras tendem a recorrer a seus colegas para a resolução de problemas. Por fim, pela análise das citações de artigos científicos, foi possível evidenciar que o conhecimento está realmente concentrado uma vez que a grande maioria das citações são para trabalhos de autores vinculados a instituições de Campinas. / This dissertation goals are review some quantitative studies of knowledge spillovers and test its tools in a brazilian case. These methods are largely adopted in international literature and, after the review, two of theses methods have been applied to the Campinas Information and Communication Technology (ICT) Local System. The discussion about characteristics, qualities and limitations of five types of studies (knowledge production function, patent citation, mobility of skilled worker, commerce of new products and informal contacts) induced to adopt the informal contact method as the main tool of analysis and a variant of patent citation that uses scientific articles citations as the primordial indicator. The questionnaire was responded by professionals engaged in ICT activities in several Campinass firms. Among the results, some are more expressive. First, there is a great presence of knowledge spillovers at Campinas region and it is an important way that ICT firms workers gain access to knowledge. Second, more skilled employees and that with more experience tend to obtain more valorous knowledge from theirs colleagues. Third, the multinationals workers gain less knowledge from theirs informal contacts because they has access to other forms inside the firm to solve problems, otherwise, the brazilian firms employees tend to use their colleagues to solve problems. Finally, with the analysis of scientific articles citations, it is possible to see some evidence that the knowledge is really locally concentrated because the great majority of citations are to works with authors linked to Campinas institutions.

This development stemmed from the realization that more important than facilities, equipment and technology are the people, the organization’s human resources. And their importance comes not only from the work they do, but, above all, from the knowledge they possess. Since tacit knowledge is inherent to learning and to practice, it cannot be displayed without the express desire of those who possess it. Within this new context, Knowledge Management (KM) has emerged to put into practice ways of making knowledge a management object, not only to be used as a measure of competitive difference, but to adapt to today’s increasingly dynamic scenario. In consequence, a case study is presented that discusses KM in the sector responsible for Information and Communications Technology (ICT) within a Federal Institution of Higher Education. Firstly, a survey was done of the sector’s current situation (structure, technology and human resources) and the possible relationship to KM; a parallel is then drawn between existing knowledge and needs, followed by a description of an IT tool compatible with a KM initiative; finally, based on the information collected in the previous steps, an evaluation is presented of the existing knowledge potential as well as its contribution to the research site’s activities. / A partir da chamada Era Pós-industrial ou Era do Conhecimento, as organizações passaram a olhar com outros olhos seus bens intangíveis. Isso decorreu da constatação de que mais importante que instalações, equipamentos e tecnologia são as pessoas, os recursos humanos da organização. E essa importância não decorre só do trabalho que as pessoas realizam, mas, principalmente, do conhecimento que elas carregam consigo. Uma vez que o conhecimento tácito é inerente ao aprendizado e a prática, ele não pode ser externalizado sem que aquele que o possui deseje. Dentro dessa nova realidade, surgiu a Gestão do Conhecimento (do termo em inglês knowledge management - KM), para pôr em prática formas de tornar o conhecimento um objeto de gestão e de utilizá-lo como um meio de diferenciação em relação não só à concorrência, mas para adaptar-se ao cenário cada vez mais dinâmico da atualidade. Em função disso, esta pesquisa, na forma de estudo de caso, traz à discussão a Gestão do Conhecimento no órgão responsável pela Tecnologia da Informação e Comunicação (TIC) em uma Instituição Federal de Ensino Superior. Em primeiro lugar, realizou-se um levantamento da situação atual do órgão (estrutura, tecnologia e recursos humanos) e a possível relação com a Gestão do Conhecimento; em seguida é traçado um paralelo entre o conhecimento existente e as necessidades; a seguir é apresentada uma ferramenta de TI compatível com uma iniciativa de GC e, finalmente, a partir de informações coletadas nas etapas anteriores é apresentada uma avaliação do potencial de conhecimento existente, assim como sua contribuição às atividades do local da pesquisa.

Syftet med examensarbetet är att beskriva vad ett antal lärare tänker kring hur en social robot skulle kunna underlätta skolsituationen för hemmasittare. Då det inte finns någon utbredd erfarenhet inom området utgår undersökningen från hur den sociala roboten fungerar för elever med hög frånvaro till följd av av sjukdom. Fyra intervjuer gjordes med lärare som har erfarenhet av arbete med den sociala roboten AV1. Utgångspunkten i intervjuerna var att fånga hur lärarna tänker att sociala robotar skulle kunna vara ett alternativ för att underlätta skolåtergång för hemmasittare. Även lärarnas erfarenheter kring hur en social robot skulle kunna användas till elever med t.ex. social fobi eller autism efterfrågades.Intervjuerna analyserades ur ett sociokulturellt perspektiv med hjälp av kodning och tematisering av innehållet i de transkriberade intervjuerna. I intervjuerna har det inte framkommit någon entydig bild i frågan om en social robot skulle kunna användas i syfte att få tillbaka hemmasittare till skolan. Däremot har vi i en av intervjuerna funnit exempel på att det kan fungera och fått ta del av vilka möjligheter och hinder respondenterna ser. Respondenter har alla uttryckt sig positivt om att använda sociala robotar i klassrummet för att en frånvarande elev ska kunna fortsätta ta del av undervisningen i klassrummet. Däremot var alla inte lika positiva när det kom till att använda sociala robotar för att försöka få hemmasittare tillbaka till skolanI examensarbetets slutliga del diskuteras implikationerna av resultatet och vilka nya frågor som väckts. Sociala robotar är ganska nya företeelser i skolans värld och arbetet har lett till att vi har fått upp ögonen för att det finns många nya områden att undersöka för att få reda på vilka möjligheter de sociala robotarna kan erbjuda. Det är en ny värld med nya verktyg och nya metoder vi behöver lära oss leva i. Allt nytt är inte bra men allt nytt är heller inte dåligt. / The aim of this thesis is to describe the thoughts of a number of teachers regarding how a social robot could be helpful in school situations for children who have long-term school absenteeism (remote students). There is no current research in this area, thus this investigation focus on how the social robot works for students with high absence due to illness instead.Four interviews were conducted with teachers with experience working with the social robot AV1. The starting point in the interviews was to capture how the teachers think the social robots could be an alternative to facilitate the return to school for remote students. Also the teachers´ experience on how a social robot could be used for students with problems such as social phobia or autism was discussed.The interviews were analysed from a socio-cultural perspective with assistance from coding and thematization from the content in the transcribed interviews.Based on the interviews, no distinct conclusion could be drawn regarding the success of a social robot in promoting the return to school of remote students. However, we have found examples in one interview which supported the use of the social robot, and were able to note the possibilities and obstacles according to the respondents. All the respondents have expressed themselves in a positive way about using social robots in the classroom. However, all were not as positive regarding the use of social robots to attempt to get children who have long-term school absenteeism back to school.In the final part of the thesis the amplifications of the results are discussed and what new questions that have arisen. The concept of social robots is a rather new phenomenon in the school environment and our work has demonstrated that there are many new areas to research to find out what new possibilities the social robots can offer. This is a new world with tools and methods that are novel, but which can be beneficial to education. Rather than being intimidated by innovative technology instruments, we must embrace their possibilities for enhancing student learning.

It is widely believed that eHealth will play a vital role in the development and shaping of healthcare systems in the twenty first century. However, despite all documented reports and benefits of eHealth technologies, many attempts to extend successful pilot projects have not sufficiently met promised results and to a large extent failed. The purpose of this study is to investigate the Centre for Rheumatology’s current implementation process of eHealth services in order to identify success factors and improvement areas. To reach the purpose, the research was delimitated to solely focus on the eHealth service Patient Self-Test and the implementation of it at the care unit.The research was conducted as a case study with a qualitative approach based on the notion of induction. The research process consisted of three major areas: pre-study, literature review and qualitative interviews. The pre-study was based on interviews with different actors within the health care industry in Sweden to provide an academic, political and business perspective of the research area. The literature review focused on the areas eHealth and change management and empirical data was gathered through qualitative interviews. Moreover, to have a tool for analysis, a research framework named 4 Seasons Model was developed.The results of the thesis indicate on a gap between how the literature advocates the implementation of transitional changes, and how it is currently done at Centre for Rheumatology’s. Based on an analysis from a 4 Seasons Model perspective, three success factors and seven improvement areas have been identified in Centre for Rhematology’s current implementation process of the Patient Self-Test.

Introduction: Ever since the transition to digital ways of working startedspreading across organizations and industries in the late 1970s, remoteworking has been a topic of interest. With the development of information andcommunications technology, virtual realities are now receiving more attentionwith a broader view of potential application areas. The application of virtualrealities is expanding. Hence, the concept of Metaverse has received a greatdeal of attention. Metaverse is a virtual reality idea where people create avatarsthat exist in a three-dimensional virtual world. While the use of virtual realitiesis expanding on new ways of working, users’ attitudes toward thesetechnological developments are important to consider as it can either increasethe benefits of working from home or highlight the negative aspects evenmore. Purpose: The purpose of this thesis is to explore the attitudes towards the useof virtual realities for remote working in the case of employees withinorganizations in Sweden. The aim is to further provide an understanding as towhat organizations need to consider following the increased use of virtualrealities. Research Questions: What are the attitudes of employees towards the use ofvirtual realities for remote working? How can organizations adapt to theimplementation of virtual realities for remote working to continuously ensurea positive work environment for its employees?  Methodology: In order to reach the purpose of this study and answer theresearch questions, a qualitative research approach was deemed appropriatefor this study to understand the “what” and “how” aspects of the use of virtualrealities for remote work. Semi-structured interviews were chosen as the datacollection method where the respondents were employees within organizationsin Sweden. Conclusion: The key takeaways are that attitudes toward virtual realities forremote working are complex. The main themes discussed around remoteworking were control and freedom to decide over one’s work and the loss ofcomradery with colleagues and social isolation. New technology, such asMetaverse, has to ensure it continues providing employees with control overtheir work but solves the issues of social isolation while still not eliminatingphysical interactions between colleagues completely. Management has todeeply consider the needs of the individual employee before implementingnew technology, gathering an understanding of what is expected and neededby their specific employees to better ensure successful implementation.

Yes / The concept of smart city is emerging as a key strategy to tackle the problems generated by the urban population growth and rapid development. It is widely recognised that Information and Communications Technology (ICT) play a key role in addressing some of the urban societal challenges such as improving energy efficiency and reducing carbon emissions. Although there are various ICT tools providing intelligence and services relating to energy consumption and monitoring processes, they mostly tend to work in isolation. Therefore, this paper presents the outcomes and impacts of the concept of DAREED which aims to deliver an integrated ICT service platform to drive energy efficiency and low carbon activities at neighbourhood, city and district levels. Furthermore, the research highlights the need for ICT-driven policy making using platforms such as DAREED in the context of e-Government. This paper contributes to the current understandings of e-Government literature in terms of how ICT can help public authorities and stakeholders such as policy makers to achieve and drive energy efficiency. From a practical stance, the paper offers valuable insights to public administrations on how ICT can be used to address pressing societal challenges such as efficient energy use and facilitate better policy making.
