Teacher Beliefs on Personal Learning, Collaboration, and Participation in Virtual Communities of Practice

Virtual communities of practice have been used to improve teachers\u27 instructional practice; yet, many of these communities do not take into account the effect of teachers\u27 personal learning and collegial collaboration beliefs on engagement within this model. The purpose of this qualitative case study was to examine if teaching was enhanced through participation in virtual communities of practice and determine if teachers\u27 personal beliefs prior to entering these communities influenced their engagement. Wenger\u27s social learning theory served as the conceptual framework. The research questions asked how teachers\u27 beliefs on personal learning and their beliefs on collaboration influenced their engagement in virtual communities of practice and how personal learning networks facilitated extended technology-based learning in the classroom. Data were collected through 2 semi structured interviews with 9 teacher participants and analysis of digital records from the Classroom 2.0 and Flat Connections Nings. Manual, open-coding of the data revealed themes which explained the use of personalized learning networks for instructional growth and social networking for collaborative practice. Findings indicated that while teachers\u27 previously held ideas were not significantly altered, the social, supportive environments created through virtual learning communities made a suitable setting for professional development. These findings may effect positive social change as virtual communities of practice for teachers evolve into professional development environments that challenge teacher beliefs, use progressive technologies, and engage teachers in collaborative activities

The virtualization of small cells as envisaged by 5G, allows enhanced mobile edge computing capabilities, thus enabling network service deployment and management near the end user. This paper presents a cloud-enabled small cell architecture for 5G networks developed within the 5G-ESSENCE project. This paper also presents the conformity of the proposed architecture to the evolving 5G radio resource management architecture. Furthermore, it examines the inclusion of an edge enabler to support a variety of virtual network functions in 5G networks. Next, the improvement of specific key performance indicators in a public safety use case is evaluated. Finally, the performance of a 5G enabled evolved multimedia broadcast multicast services service is evaluated.Peer ReviewedPostprint (author's final draft

A Pragmatic Study of Female and Male Discourse Use on Facebook

La comunicación virtual es un campo de estudio muy interesante e innovador que analiza las distintas estrategias comunicativas empleadas en este tipo de discurso que difieren de las empleadas en la comunicación verbal. Este trabajo empieza revisando investigaciones precedentes en este tema para posteriormente analizar, desde un punto de vista pragmático, las diferencias del uso del discurso femenino y masculino en Facebook, sin caer en una perspectiva sexista. El problema principal en este estudio ha sido intentar establecer dicha comparación. Para poder acometer este estudio, recurrimos primero al análisis descriptivo de un corpus creado con discursos reales sacados de la propia red social, para elaborar un cuestionario Likert de 5 puntos, y poder realizar así un estudio experimental que nos permitiera probar si los marcadores textuales utilizados por hombres y mujeres difieren en sus respectivos discursos. Los resultados revelaron una diferencia estadísticamente significativa entre ambos tipos de discursos al comunicarse en Facebook. Sin embargo, también obtuvimos algunos resultados inesperados en relación al uso de los marcadores discursivos utilizados por el grupo de mujeres jóvenes que eran muy parecidos a los utilizados por los hombres en ambas condiciones, tanto en los jóvenes como en los adultos. Por esta razón, la conclusión es que existen rasgos distintivos en los usos discursivos femeninos y masculinos, aunque en el caso de las mujeres jóvenes su discurso parece estar cambiando, puesto que se asemeja cada vez más al discurso masculino. No obstante, sería necesario llevar a cabo una investigación sobre el cambio discursivo de las mujeres jóvenes para tratar de establecer sus causas.Virtual communication is an interesting and innovative field study which analyses the communicative strategies used in this type of discourse, different from the ones used in face-to-face communication. This work first reviews some previous research on the topic to then analyse from a pragmatic perspective the differences between female and male discoursre uses on Facebook, without succumbing to a sexist perspective. To carry out this analysis, we resorted to a corpus made with real conversations from Facebook to elaborate a 5-pint Likert scale, and so conduct an experimental survey to test whether women and men actually use different discourse markers in their respective discourses. The results revealed that there was a statistically significant distinction in the female and male discourse use when communicating on Facebook. However, some unexpected results were also obtained regarding the discourse markers used by women in the female young adult group condition, which were very similar to those used by men in both the young adult and adult condition. Hence, the conclusion is that there are distinctive features of both female and male discourse use that allow us to identify the two different gender identities, though young women’s discourse use seems to be changing and increasingly resembling to the male discourse. Further research is needed to shed some more light on the change of discourse use found in young women to try to determine its causes.31 páginas y anex

A Comparative Evaluation of the Internets Influence on International Market Penetration and Development Strategies of Australian SME's

The Internet has the capability to generate geographical international market expansion and future growth for the firm, a concept known as Internetalisation. However, it is yet to be determined as to how much or to what level the Internet influences internationalisation, and thus international market growth. Both international market penetration and the development of new international customers are achievable goals for the Internet enlightened SME. The aim of this research is to explore the influence of the Internet on international market penetration and development from the strategic perspective of the SME in Australia. It was found that although the Internet has given firms the capabilities to become instantly international, a new theory is not needed but rather an evolved version of network theory may be a better explanation of internationalisation of SME’s in today’s digital environment

Sensor function virtualization to support distributed intelligence in the internet of things

It is estimated that-by 2020-billion devices will be connected to the Internet. This number not only includes TVs, PCs, tablets and smartphones, but also billions of embedded sensors that will make up the "Internet of Things" and enable a whole new range of intelligent services in domains such as manufacturing, health, smart homes, logistics, etc. To some extent, intelligence such as data processing or access control can be placed on the devices themselves. Alternatively, functionalities can be outsourced to the cloud. In reality, there is no single solution that fits all needs. Cooperation between devices, intermediate infrastructures (local networks, access networks, global networks) and/or cloud systems is needed in order to optimally support IoT communication and IoT applications. Through distributed intelligence the right communication and processing functionality will be available at the right place. The first part of this paper motivates the need for such distributed intelligence based on shortcomings in typical IoT systems. The second part focuses on the concept of sensor function virtualization, a potential enabler for distributed intelligence, and presents solutions on how to realize it

Healthcare PANs: Personal Area Networks for trauma care and home care

The first hour following the trauma is of crucial importance in trauma care. The sooner treatment begins, the better the ultimate outcome for the patient. Generally the initial treatment is handled by paramedical personnel arriving at the site of the accident with an ambulance. There is evidence to show that if the expertise of the on-site paramedic team can be supported by immediate and continuous access to and communication with the expert medical team at the hospital, patient outcomes can be improved. After care also influences the ultimate recovery of the patient. After-treatment follow up often occurs in-hospital in spite of the fact that care at home can offer more advantages and can accelerate recovery. Based on emerging and future wireless communication technologies, in a previous paper [1] we presented an initial vision of two future healthcare settings, supported by applications which we call Virtual Trauma Team and Virtual Homecare Team. The Virtual Trauma Team application involves high quality wireless multimedia communications between ambulance paramedics and the hospital facilitated by paramedic Body Area Networks (BANs) [2] and an ambulance-based Vehicle Area Network (VAN). The VAN supports bi-directional streaming audio and video communication between the ambulance and the hospital even when moving at speed. The clinical motivation for Virtual Trauma Team is to increase survival rates in trauma care. The Virtual Homecare Team application enables homecare coordinated by home nursing services and supported by the patient's PAN which consists of a patient BAN in combination with an ambient intelligent home environment. The homecare PAN provides intelligent monitoring and support functions and the possibility to ad hoc network to the visiting health professionals’ own BANs as well as high quality multimedia communication links to remote members of the virtual team. The motivation for Virtual Homecare Team is to improve quality of life and independence for patients by supporting care at home; the economic motivation is to replace expensive hospital-based care with homecare by virtual teams using wireless technology to support the patient and the carers. In this paper we develop the vision further and focus in particular on the concepts of personal and body area networks

New Media and the Quality of Life

We are currently in the middle of a revolution. This revolution, sometimes called the digital revolution, is the revolutionary transformation brought about in the information and communication structure of society by the advent of the digital computer, with most of the major transformations having taken place in the past thirty years. Digital computing technology has generated the mainframe and personal computer, the multimedia computer, and computer networks. It has also transformed the telephone system and the monetary system, it is transforming all kinds of conventional products ranging from washing machines to automobiles, and it is on its way to change television as well. More than ever, contemporary society is an Information Society, in which the importance of information and communication is much greater than in past societies, and of which technologies that facilitate information and communication processes are a central societal feature. In this paper, I want to evaluate the implications of contemporary information and communication media for the quality of life, including both the new media from the digital revolution and the older media that still remain in use. My evaluation of contemporary media will proceed in three parts. In the section to follow, the benefits of contemporary media will be discussed, with special emphasis given to their immediate functional benefits. The section thereafter is devoted to a discussion of four potential threats posed by contemporary media. In a final major section, I look at the future of digital media and the possibilities available to us in shaping that future. A short concluding section ends the paper

Emerald does not grant permission for this article to be further copied/distributed or hosted elsewhere without the express permission from Emerald Group Publishing Limited.This article was chosen as a Highly Commended Award Winner at the Emerald Literati Network Awards for Excellence 2013.Purpose – The paper aims to report on an exploratory study into how small businesses use Web 2.0 information and communication technologies (ICT) to work collaboratively with other small businesses. The study had two aims: to investigate the benefits available from the use of Web 2.0 in small business collaborations, and to characterize the different types of such online collaborations. Design/methodology/approach – The research uses a qualitative case study methodology based on semi-structured interviews with the owner-managers of 12 UK-based small companies in the business services sector who are early adopters of Web 2.0 technologies. Findings – Benefits from the use of Web 2.0 are categorized as lifestyle benefits, internal operational efficiency, enhanced capability, external communications and enhanced service offerings. A 2×2 framework is developed to categorize small business collaborations using the dimensions of the basis for inter-organizational collaboration (control vs cooperation) and the level of Web 2.0 ICT use (simple vs sophisticated). Research limitations/implications – A small number of firms of similar size, sector and location were studied, which limits generalizability. Nonetheless, the results offer a pointer to the likely future use of Web 2.0 tools by other small businesses. Practical implications – The research provides evidence of the attraction and potential of Web 2.0 for collaborations between small businesses. Originality/value – The paper is one of the first to report on use of Web 2.0 ICT in collaborative working between small businesses. It will be of interest to those seeking a better understanding of the potential of Web 2.0 in the small business community.WestFocu

Understanding insertion and integration in a study abroad context: the case of English-speaking sojourners in France

This paper draws on a recent study of British students of languages undertaking a year abroad in France, in a variety of placements (as language teaching assistants, as exchange students, and as workplace interns). The data were gathered in the context of the 2011-2013 LANGSNAP project, a larger study undertaken which investigated both the language learning and social integration of British students spending an academic year abroad in France, Spain or Mexico Having made a positive choice to specialise in languages at university, and having already reached a relatively advanced level in French during their secondary school education, it could be assumed that these students were positively motivated to further develop their language skills, to deepen their intercultural understanding, and to integrate socially within the local society. Indeed, in pre-departure interviews (in French), the participating students unanimously expressed the wish to integrate and in particular to make French same-aged friends. The paper first of all presents an overview of the range of tools used to gather both quantitative and qualitative data on participants’ social integration. The paper then goes on to evaluate the degree of success of even such highly motivated participants in achieving this declared goal, and to consider social, sociolinguistic and personal factors which appear to influence the degree of social integration achieved by individual participants
