Full textAbstract:
Previous studies demonstrate that online interactive relations can help improve users' innovation outcomes, yet few studies have investigated how they influence user innovation. This paper builds a social network based on users' online interactive relations in one virtual innovation platform (LEGO Ideas). It characterizes the online social network relations from both quantity and quality dimensions and examines their influencing paths on users' innovation outcomes (i.e., emotional support and information flow). The empirical results show that both the quantity and quality of online relations impose positive effects on innovation, yet in different ways. The quantity of online relations could bring users more positive emotions, whereas the quality of online relations could bring them with more useful information and knowledge. By examining the influencing paths, this paper contributes to the literature on how online relations influence innovation outcomes as well as provides practical suggestions for innovation platforms.

This article focuses on the Tamil diaspora in the context of virtual networks. Contemporary linkages stem from decades of civil unrest within Sri Lanka. The Tamil community has found much unity in perceived injustices and marginalization following a violent mass exodus during the 1980s. Quests for political validation and statehood in North-East Sri Lanka have transferred to virtual platforms. Subsequent networks are both sophisticated and dynamic, proactively transcending borders, propelling transnational linkages forward. Between the virtual and physical, the article investigates how respective communities network and expand online. This includes mapping online activities, which characteristically focus on current affairs and ground realities. Indeed, the Web provides a platform of engagement, which in a quest for legitimacy has expanded the networked opportunities available for the greater Tamil diaspora.

In social networks, social foci are physical or virtual entities around which social individuals organize joint activities, for example, places and products (physical form) or opinions and services (virtual form). Forecasting which social foci will diffuse to more social individuals is important for managerial functions such as marketing and public management operations. In terms of diffusive social adoptions, prior studies on user adoptive behavior in social networks have focused on single-item adoption in homogeneous networks. We advance this body of research by modeling scenarios with multi-item adoption and learning the relative propagation of social foci in concurrent social diffusions for online social networking platforms. In particular, we distinguish two types of social nodes in our two-mode social network model: social foci and social actors. Based on social network theories, we identify and operationalize factors that drive social adoption within the two-mode social network. We also capture the interdependencies between social actors and social foci using a bilateral recursive process—specifically, a mutual reinforcement process that converges to an analytical form. Thus, we develop a gradient learning method based on a mutual reinforcement process that targets the optimal parameter configuration for pairwise ranking of social diffusions. Further, we demonstrate analytical properties of the proposed method such as guaranteed convergence and the convergence rate. In the evaluation, we benchmark the proposed method against prevalent methods, and we demonstrate its superior performance using three real-world data sets that cover the adoption of both physical and virtual entities in online social networking platforms.

Full textAbstract:
Delay Tolerant Network (DTN) is a kind of network structured to deliver message intermittently. Network connections are not persistent between nodes, instead they must rely on nodes making geographic location movements to incur contact with other nodes and establish intermittent communication sessions to allow messages delivery. We will refer to encounters via geographic location movements as ?physical contact.? Many DTN researches mainly focus on message delivery via physical contact. However, this paper believes that in a realistic environment, encounters between nodes not only happen geographically in nature, but also occur virtually in cyberspace. When both nodes go online on the same social media platform, it is an encounter we refer as virtual contact. How messages deliver for virtual contact is store-post-and-forward, just like what happens in a DTN, but it is no longer restrained by geographical locations. This paper considers a scenario in which nodes make virtual contact in cyberspace and incur message delivery based on their own behavior patterns. The verifying experiment is conducted using both survey and simulation. First of all, we handed out questionnaires for students to fill out. The questionnaire inquired them to rank their most frequent activities performed on social media platforms. According to the responses, we conclude the top 3 frequent activities when the students use social media platforms and classify them into 3 groups according to a weighted behavior pattern scheme. The classification includes Social Group, Read-Only Group and Interest Group. It does not matter which group a student is assigned to. In the simulation, he or she will get to decide whether to deliver/receive messages or not based on a randomized selection on 3 behavior pattern. Finally, we analyze the simulation result to determine how messages propagated in different behavior pattern groups. It is derived from the simulation that to quicken message propagation, directing messages to one of the behavior groups yields the maximize benefits. This provides the basis for further researches on collecting data of desired scenarios to establish respective propagation models.

This study aims to analyze communication in virtual communities that are reviewed from a business, health and career-linkedIn perspective. This research uses the literature review method through literature search both books and international and national journals. The results showed that the virtual community was established and developed through Computer Mediated Communication (CMC) on various platforms. Virtual communities develop because individuals have the same goal. They bind themselves to join and exchange ideas, information in a virtual community because there are common motives and goals to be achieved. There are several similarities and differences that bind individuals to join virtual communities from a business, health and career-linked perspective. Trust and security are the main keys of individuals joined in virtual communication in various fields. In addition, in the business perspective, two reasons individuals join online trade are the use of a conducive community and virtual social environment. While in the context of health, the reason the community joins is the ease of accessing health information, trust and security of user data. Finally, in the context of career-linked development, individuals tie themselves into the community because this platform has advantages in forming social network capital, knowledge capital to form friendships. Virtual communities on various platforms (business, health and careers) continue to grow and are increasingly being asked by users.

IntroductionAdvances in information and communication technology (ICT) and health technology have enhanced healthcare for many countries around the world. The challenge for low income setting countries is to build a telemedicine platform to enhance the community hospital diagnosis response capacity. Populations living in remote areas did not have access to specialist care and quality diagnostic services and thus depended on the low response capacity of their local health system. There were subsequent equity issues between urban and rural populations. In this context the virtual telediagnosis network should be directed towards developing better equity in the provision of services in remote locations without access to specialists. The usability of a telemedicine platform to enhance the virtual diagnosis network of community hospitals in rural areas of Paraguay was investigated.MethodsThis descriptive study was carried out by the Telemedicine Unit of the Ministry of Public Health and Social Welfare (MSPBS) in collaboration with the Department of Biomedical Engineering and Imaging of the Health Science Research Institute (IICS-UNA) and the University of the Basque Country (UPV / EHU) to evaluate the utility of a telemedicine platform to enhance the virtual diagnosis network of community hospitals. For this purpose, the results obtained by the virtual telediagnosis network implemented in sixty public countryside community hospitals were analyzed.ResultsA total of 427,026 remote diagnoses were performed between January 2014 and October 2018 in sixty community hospitals. Of the total, 35.76 percent (152,703) corresponded to tomography studies, 62.55 percent (267,100) to electrocardiography (EKG), 1.68 percent (7,204) to electroencephalography (EEG) and 0.01 percent (19) to ultrasound. There were no significant differences between the remote and the face-to-face diagnosis. With the remote diagnosis a reduction of the cost was obtained, that supposes an important benefit for each citizen of the sixty communities.ConclusionsThe results show that the virtual diagnosis network based on a telemedicine platform can enhance significantly the community hospital diagnostic services, maximizing professional time and productivity, increasing access and equity, and reducing costs. However, before carrying out its countrywide implementation, a contextualization with the regional epidemiological profile must be performed.

"Finding value in social media: A collaborative online communication platform linking providers to education and an online tumor board across a large community of oncology practices." Journal of Clinical Oncology 38, no. 29_suppl (October 10, 2020): 305. http://dx.doi.org/10.1200/jco.2020.38.29_suppl.305.
Full textAbstract:
305 Background: Clinical collaboration across fragmented and often small clinic sites can be challenging. As a potential solution, OneOncology, a national community oncology network, launched OneCommunity, a secure, interactive online platform used across our network of six practices and over 130 clinic sites. One feature is a “virtual” tumor board where physicians can post complex cases at any time and obtain input from disease-specific experts from within the network. Members can also post, comment and disseminate information about policy and education updates affecting oncology. Methods: OneCommunity launched on December 15, 2019 and all 442 members of OneOncology were allowed access. We tracked numbers of membership, tumor board cases, policy updates and questions, views and responses per post, and response time for tumor board and policy posts during the study period from launch through June 11, 2020. Results: In the first six months of use, 277 providers signed up and logged into the platform. 71 individual patient cases were presented across 10 specialty tumor boards. The mean time to first response was 35 hours ( < 1 hour, 297 hours), median time was 20 hours, and 73% of postings had a response within 48 hours of original posting. The most robust tumor boards were breast, GI, and lung cancers. There was also a set of general posts that was nonspecific to patients including policy, COVID updates, and educational reviews. The average number of responses for tumor boards was significantly greater than general posts (3.5 vs. 1.8, p < 0.05). The number of views for both types of posts, however, were high (406 vs. 346, p < 0.05). Conclusions: An online communication platform is feasible and allows physicians to receive treatment suggestions for complex cases relatively quickly and across geographies. Tumor board cases received more interaction than policy and education updates. The platform lends itself to rapidly adding other aspects of cancer care such as COVID-19. Future applications include a network wide real-time molecular tumor board.

With the increasingly salient social influence of virtual practice, personalized lifelong learning concept could be realized through network platform. The new learning environment and platform generate the new evaluation system and model. The working experience and features of network learning of the meteorological technical personnel determine the difference between network evaluation model and the traditional summative evaluation system.. The nonlinearity between input vector and output vector also determines the neural network learning evaluation model orientation. The training and simulation show that the network learning evaluation achieves its best effect when the hidden node is 4.

PurposeExploring the antecedents of members community participation is extremely important for virtual communities (VCs) research and practice. As an important social characteristic of individuals, social embeddedness has been proved as an important antecedent of many individual behaviors; however, few research has investigated the influence of virtual community members social embeddedness on virtual community members’ participation. To fill this gap, the purpose of this paper is to explore the relationship between social embeddedness and community participation in VCs.Design/methodology/approachThis paper conducted empirical study to test the hypotheses. Based on existing scales, this research designed the questionnaire and used a web-based survey to collect the data from VCs in China. To avoid the common method bias, this study collected data at two different times. The final sample included 96 virtual community members from seven communities (community size ranging from 10 to 25) of Baidu Tieba, which is the largest Chinese online communication platform. And this paper used regression models to analysis the data.FindingsBased on social network theory, this paper found that virtual community members’ social embeddedness in their virtual community has a curvilinear (i.e. inverted U-shaped) effect on their community participation behaviors. And members’ perceived autonomy mediates the curvilinear (i.e. reversed U-shaped) relationship between social network embeddedness and community participation. Furthermore, member instability moderates the curvilinear (i.e. inverted U-shaped) main effect, such that the curvilinear relationship is weakened when member instability is high.Originality/valueDeparting from previous virtual community studies that examine antecedences of participation in linear logic, this study applied social network theory to create a complex, curvilinear, moderated mediation model. The result reveals a curvilinear (i.e. inverted U-shaped) relationship between virtual community members’ social embeddedness in the virtual community and their community participation. And this study also introduce autonomy as mediator and member instability as moderator. By testing the whole model between community members’ social embeddedness and community participation, this study contributes to deepen the understanding of social embeddedness and virtual community participation.

Because of the evolution of community supported collaborative learning (CSCL), the online community has become a necessary aspect of most companies and organizations. Previous research has indicated that employee community commitment is the fundamental function of an organization, which has proven to affect a person's teamwork performance. However, research focused on how the online community-supported collaborative virtual environment, such as enterprise social network (e.g., Yammer) or virtual working space (e.g., SUN's Wonderland) might alter community commitment to affect a person's teamwork self-efficacy is scant. The authors examine the mediating role of community commitment with emotional social support as an independent variable and teamwork performance as an output variable. World of Warcraft (WOW), a dynamic high-fidelity virtual environment that can support hundreds to thousands of people collaborating together, serves as the research platform in this study.The authors conducted hierarchical regression analysis to explore the causal-effect relationship among the factors of emotional social support, community commitment, and teamwork self-efficacy. In total, 558 current company employees selected from WOW participated in an online survey. The authors' findings showed that individual commitment positively influences teamwork self-efficacy. To increase individual commitment, the online community can provide a high level of emotional social support to members.

Full textAbstract:
This article is dedicated to examination of approaches towards production of knowledge in the conditions of development of the digital methods of communication. The development of technologies and Internet concept Web 3.0 form a request for collective, interdisciplinary and “civil” character of research activity, emergence of new practices of working with knowledge, focused on confluence of the virtual and real space, transformation of the essence and role of “information” in the context of building the “society of knowledge”. The modern scientific knowledge represents a synthesis of various aspects of science and social life. Within the framework of pilot research, the author analyzes the case of confluence of the digital and real activity in production of knowledge: “public space of collective work ‘the pivotal point’” and digital platform Leader-ID. The article considers the hypothesis that the modern scientific knowledge represents a synthesis of social, culturological, and technological aspects of science and social life. The “distributed knowledge”, forming as a result of cooperation of scholars and various communities, becomes common through the formation of “cluster” and crowdsourcing format of the production of knowledge. Such social interaction is based on the network platform model and generated new zones of exchange and production of knowledge: online platforms (forums, crowdsourcing, scientific network platforms such as ResearchGate, simulators, etc.) or offline platforms (public spaces) that discuss and formulate the requests of scholars to each other, formulate hypothesis, and test the studies.

Full textAbstract:
This paper contributes to debates about the implications of digital technology for social research by proposing the concept of the redistribution of methods. In the context of digitization, I argue, social research becomes noticeably a distributed accomplishment: online platforms, users, devices and informational practices actively contribute to the performance of digital social research. This also applies more specifically to social research methods, and this paper explores the phenomenon in relation to two specific digital methods, online network and textual analysis, arguing that sociological research stands much to gain from engaging with their distribution, both normatively and analytically speaking. I distinguish four predominant views on the redistribution of digital social methods: methods-as-usual, big methods, virtual methods and digital methods. Taking up this last notion, I propose that a redistributive understanding of social research opens up a new approach to the re-mediation of social methods in digital environments. I develop this argument through a discussion of two particular online research platforms: the Issue Crawler, a web-based platform for hyperlink analysis, and the Co-Word Machine, an online tool of textual analysis currently under development. Both these tools re-mediate existing social methods, and both, I argue, involve the attempt to render specific methodology critiques effective in the online realm, namely critiques of the authority effects implicit in citation analysis. As such, these methods offer ways for social research to intervene critically in digital social research, and more specifically, to endorse and actively pursue the redistribution of social methods online.

This article addresses the complex relationship between digital activism and Internet art, from the initial proposals in the 1990s up to the present day. The analysis focuses on those projects that have most impacted the convergence of net art and “net-activism” during this period, with a particular emphasis on the relationship between artistic practice and hacktivism. Likewise, phenomena such as virtual sit-ins, DDOS-based strategies and several others that have emerged in the new context of social networks and participatory online platforms (memes, flash mobs, etc.) are analysed, in order to reflect on the new practices of social media art and their potential for specific critical action.

Purpose This paper aims to examine how media play a role in community responses to disaster. The authors explore how communication technology may allow new relationships between community groups and emergency agencies. The authors examine the context within which warnings and risk communication are interpreted by media services. The authors observe how, in an emergency context, the thinking about media may change from that of a linear framework of information provision to one of shared resources. Design/methodology/approach The authors focus on Second Life, a shared, online space which uses 3D graphic images to simulate a virtual environment. Second Life is posited as a media tool with clear advantages for the training of emergency services professionals and citizens in the community. The authors observe emergency training scenarios and advantages for training for critical thinking and decision-making. Findings The authors observe then how virtual worlds such as Second Life provide an online forum in which participants can interact, communicate and simulate action in a complex 3D graphic environment. Second Life may be a useful medium for simulating and testing geo-physical and social manoeuvres using the modeling tools. This may allow for collaborative decision-making in simulations which can prepare or rehearse people for emergency conditions. It may be useful in an emergency with information streamed and coordinated at a single online site. A shared network like Second Life may be shared by many people co-synchronously or a-synchronously, despite their geographic distance. Second Life applications may also be useful in the aftermath of emergencies for design and rebuilding, for analytical and educational purposes. Research limitations/implications It is clear that social networks like Second Life provide a valuable tool with which to learn about and share data and information about bushfires, community emergencies and safety precautions in a social setting. It can also provide, at the local level, a forum for community information and discussion, as well as for counselling and reconstruction in the aftermath. Practical implications The authors suggest that the range and flexibility of tools and their excellent geographic visualization and social networking functions may in future allow for learning and decision-making among diverse and disparate groups who can come together in virtual space. It is especially useful in remote communities as a means of uniting people who are otherwise isolated by distance or trapped in emergency situations. Second Life is useful for sharing information, organizational and local knowledge about disaster and mitigation management. This media-rich platform is valuable to a community that is increasingly adept with shared, 3D graphic computer interfaces. Social implications Applications like Second Life may provide a space where users can access a range of tools as a means of informing, educating, empowering and warning participants in emergency scenarios, both real and simulated. They are more than virtual spaces; they are also social spaces. A platform like Second Life may provide a virtual solution for such communication challenges especially where communities are too remote, too dispersed or even too many in number to be easily accessible in the field. Originality/value This paper contains new and significant information about emerging communication systems and platforms that may be of use to those researching and planning around disaster management, mitigation and resilience. It addresses the use of new techniques which are the result of innovation in technology, software design and network design. It applies a discussion of these techniques to several hypothetical and real-life scenarios to explore the potential for virtual tools as a way of providing enriched information, mapping and communication tools across a range of disaster response scenarios.

Online educational platforms have recently been used to compensate for educational activities that have been interrupted all around the world due to the pandemic during the year 2020. This study was conducted to reveal reflections of e-learning on social studies courses. Among qualitative research designs, the case study method was used. The data were collected using semi-structured interview. The study group consisted of 27 social studies teachers working in public secondary schools in Adıyaman province of Turkey. Those teachers were determined based on purposeful sampling method. These teachers were determined based on non-random purposeful sampling criterion. They were interviewed considering that they used the online education platform intensively during the pandemic and had the necessary experience to make evaluation in this regard. The data were collected between September and November 5, 2020. The data were analysed using inductive analysis. The study results showed that social studies teachers could not literally adapt to e-learning activities due to their lack of knowledge about using computers. They did not internalize virtual education but had a perception that such education could be used as a supportive one for face-to-face education or for review. The study found that the EBA (Education Information Network), the most comprehensive online educational platform in Turkey, could not literally meet the needs in terms of infrastructure and content. Teachers endeavoured to adapt to e-learning during the pandemic and they welcomed admiringly the preparations made by the MEB (Ministry of National Education) despite the deficiencies therein. The majority of teachers stated they did not receive any course related to e-learning during their undergraduate education. In-service e-learning training can be provided to social studies teachers. E-learning courses can be included in the programs in education faculties. The Ministry of National Education can enrich its infrastructure.

Purpose The purpose of this paper is to identify the factors influencing the growth of healthcare virtual communities of practice (VCoPs) through a seven-year longitudinal study conducted using metrics from social-network and semantic analysis. By studying online communication along the three dimensions of social interactions (connectivity, interactivity and language use), the authors aim to provide VCoP managers with valuable insights to improve the success of their communities. Design/methodology/approach Communications over a period of seven years (April 2008 to April 2015) and between 14,000 members of 16 different healthcare VCoPs coexisting on the same web platform were analysed. Multilevel regression models were used to reveal the main determinants of community growth over time. Independent variables were derived from social network and semantic analysis measures. Findings Results show that structural and content-based variables predict the growth of the community. Progressively, more people will join a community if its structure is more centralised, leaders are more dynamic (they rotate more) and the language used in the posts is less complex. Research limitations/implications The available data set included one Web platform and a limited number of control variables. To consolidate the findings of the present study, the experiment should be replicated on other healthcare VCoPs. Originality/value The study provides useful recommendations for setting up and nurturing the growth of professional communities, considering, at the same time, the interaction patterns among the community members, the dynamic evolution of these interactions and the use of language. New analytical tools are presented, together with the use of innovative interaction metrics, that can significantly influence community growth, such as rotating leadership.

Introduction: A novel initiative allowed third year medical students to pursue experiential learning during a year-long Enrichment Year programme as part of the core curriculum. ‘connect*ed’, an online virtual community of learning was developed to provide learning and social support to students and to help them link their diverse experiences with the common goal of being a doctor. This study examined the nature, pattern, and content of online interactions among medical students within this community of learning to identify features that support learning and personal growth. Methods: This was a quantitative-qualitative study using platform data analytics, social network analysis, thematic content analysis to analyse the nature and pattern of online interactions. Focus group interviews with the faculty mentors and medical students were used to triangulate the results. Results: Students favoured online interactions focused on sharing and learning from each other rather than structured tasks. Multimedia content, especially images, attracted more attention and stimulated more constructive discussion. We identified five patterns of interaction. The degree centrality and reciprocity did not affect the team interactivity but mutual encouragement by team members and mentors can promote a positive team dynamic. Conclusion: Online interactions that are less structured, relate to personal interests, and use of multimedia appear to generate the most meaningful content and teams do not necessarily need to have a leader to be effective. A structured online network that adopts these features can better support learners who are geographically separated and engaged in different learning experiences.

Much research has demonstrated the power of social norms to affect proenvironmental behavior and conservation-related attitudes and beliefs in traditional “offline” social contexts. With the emergence of social media and citizen science platforms that allow for socially coordinated conservation efforts at scale comes a need to better understand the influence of social norms in online contexts. The present experiment explored effects of norm violations on impression formation and intergroup judgments within the context of Habitat Network, a socially networked mapping application where users create and share virtual representations (maps) of their properties. Results revealed that when participants viewed a map depicting the violation of a strongly held group norm—namely, the presence of an outdoor (vs. indoor) pet cat—they judged the map owner as significantly less likely to engage in a variety of proenvironmental behaviors. Importantly, this effect emerged despite evidence that the owner was already engaging in various sustainable practices. Moreover, the effect was mediated by the perceived quality of wildlife habitat represented by the map and moderated by participants’ group membership status (as a cat owner) in a manner consistent with theories of impression formation and intergroup judgments. We discuss implications for social cognition and intergroup relations in proenvironmental online contexts.

Full textAbstract:
Social media provides a virtual workplace/network where people can enjoy expressing their opinions, exchange opinions, disseminate and control messages anywhere and anytime. Marketers are now able to reach consumers and interact with them using social media. The present study investigates the relations between communications on the social network platforms and its effect on the purchase intentions of young consumers towards financial products. Different statistical techniques were used to assess and validate the constructs selected for the study. Subjective content validity (based on structured interviews), reliability tests (using Cronbach’s alpha [α]), exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) for evaluating the factor structure and initial validity were used for the investigation. The findings suggest that user-generated social media communication (UGSMC) such as customer reviews plays an important role in creating positive perception towards online purchase of financial products, thereby impacting the brand attitude (BA) and brand equity. The perception of consumers is built on what they see and hear on social media platforms. There is a positive influence of social media on the online purchase of financial products. Social media influences information at different stages of customer decision-making.

Full textAbstract:
Social network sites like Twitter enable the creation of virtual environments where online communities are formed around specific topics. Lately, due to their increasing success, these platforms are turning out to be effective for electronic word–of–mouth communication since they can be used as another means to spread information and build a network of contacts. In this paper, Twitter is used as a proxy to measure social capital in the electronics and ICT cluster, one of the 22 clusters integrated in the Basque cluster policy. Tweets were extracted through REST and Streaming API and later on studied using Social Network Analysis, both from the static and dynamic perspective. Above all, I highlight a strong correlation at the structural and relational level, intra and inter dimensionally. The social and organizational proximity may explain the tighter relationships among affiliates, where the association that rules the cluster and other firms play an important role.

Constructivist teaching in virtual environments places particular emphasis on the use of discussion forums. This article presents the implementation of a concept of constructivist didactics through an e-learning course on the Blackboard platform of the Department of Education at the University of Salzburg, Austria. Students were motivated to build knowledge through their participation in discussion forums on the Blackboard platform. Teachers, in their role of moderators, expected to be able to gradually reduce their presence in the debates. The challenge was to be able to measure the extent to which this was achieved, considering that thousands of discussion contributions had to be analyzed. This document describes how the discussion lines can be extracted from Blackboard to be used by UCINET software for social network and thus produce a graphic presentation of the discussion sequences.

Abstract This study aimed to analyze how the Social Software tools could respond to the needs of parents and teachers of students with multiple disabilities in improving their practices, as well as provide information and resources related to the topic of multiple disabilities. The study was implemented in Portugal and involved 45 participants: 25 special education teachers, 5 regular education teachers, and 15 parents of children with multiple disabilities. Using the NING platform, we built a social network, which we set in motion by creating online spaces to share experiences and thoughts. These spaces sought to respond to the needs and difficulties reported by the participants. We adopted a Design-Based Research methodology and used several data collection methods and analysis techniques. The results showed that several dimensions were crucial to create this Social Network, such as the tools, the moderation and the management of the social network and the participation of the teachers and parents involved. It also confirmed that the flexibility of the tools used led to the development of a stimulating environment that allowed sharing experiences and knowledge about multiple disabilities. The teachers' participation revealed progress over time. The most active participants assumed attitudes of creator and critic, whereas the roles of collector, spectator and inactive were taken on by those with a more passive attitude. The teachers exhibited more active attitudes than parents. The teachers' assessment of the social network was positive for all the aspects under study and they felt that their participation had a significant impact on teaching practices. Results indicate that parents did not actively get involved in the social network, which shows that virtual contacts may not properly serve their needs. We infer that parents need a different approach, more focused on supporting and less on learning. Overall, the study indicated that the Social Software allowed co-created knowledge among teachers, sharing of experiences, thoughts and resources, along with supporting better connections and cooperative learning. Nevertheless, such co-creation can only be achieved if participants take an active role in the use of the Social Network.

ObjectiveCurrently, use of social networking services (SNSs) for interprofessional collaboration is increasing. However, few studies have reported on virtual interprofessional interactions in community healthcare services. Revealing such structural characteristics of the networks can provide insight into the functions of the interprofessional information-sharing network and lead to smoother collaboration. Thus, we aimed to explore the structure of SNS-based information-sharing clinical networks.DesignSocial network analysis (SNA).SettingWe selected a community in City X in Japan.Data collectionWe analysed SNS-based information-sharing clinical network data linked to patients receiving home medical care or care services between January and December 2018. A network was created for each patient to allow healthcare professionals to post and view messages on the web platform. In the SNA, healthcare professions registered in a patient group were represented as nodes, and message posting/viewing relationships were represented as links in the patient network. We investigated the structural characteristics of the target networks using several measures for SNA, including indegree centrality and outdegree centrality, which reflect the number of incoming and outgoing links to/from a node, respectively. Additionally, the professions forming the most central nodes were investigated based on their ranking to identify those with a central role in the networks. Finally, to compare the networks of nursing care levels 1–3 (lighter care requirement) and those with nursing care levels 4–5 (heavier care requirement), we analysed the structural differences in the networks and investigated the roles of healthcare professionals using centrality measures of nodes.ResultsAmong 844 groups, 247 groups with any nursing care level data were available for analysis. Increasing nursing care level showed higher density, reciprocity and lower centralisation. Healthcare professions with high indegree centrality (physicians, care workers and physical therapists) differed from those with high outdegree centrality (home care workers, physical therapists, and registered dieticians). Visiting nurses and nurses in the clinic played a central role, but visiting nurses tended to have higher indegree and outdegree centrality, while nurses in the clinic had higher closeness and betweenness centrality in networks with heavier care requirement.ConclusionThe SNS-based information-sharing clinical network structure showed that different professions played some form of a central role. Associations between network structures and patient outcomes, cost effectiveness and other factors warrant further investigation.

In developing nations where distance education is viewed with great interest, cloud computing provides a necessary solution in creating a 21st century educational environment. Cloud computing facilitates the use of open source in educational institutions in the online learning environment where the social web or software can be used to network institutions, libraries, and students in their homes. This approach enables remote laboratories for educational institutions, research, and industry. Combining this with a virtual platform will provide academic institutions the ability to provide instruction, and research establishment to conduct high level complex research. This paper presents the concept of laboratories at home as the authors see it in the light of cloud computing era, taking into account the existing norms and standards as well as achieve educational goals required for science and engineering laboratories with what can be referred to as Networked Smart Educational Devices.

The aim of this paper is to determine whether the younger population in Croatia is following the dominant world trends in the use of social networks as extremely widespread communication platforms. Namely, although the Facebook community currently consists of as many as two billion users and is still convincingly the most popular social network in the world, it has already been noted that members of the so-called generation Z (people born after 1995) across the world are increasingly abandoning or minorizing Facebook and turning to other social networks. To this end, the authors used the comparative method to investigate the use of several contemporary social networks and current trends in the world and Croatia, using the necessary theoretical framework. Also, during May of 2017, the authors conducted a research into online habits and attitudes on social networks – which has not yet been done in Croatia, in the authors' knowledge – by means of an online survey among secondary school students, members of generation Z, in several major and smaller Croatian cities: Zagreb, Osijek, Krk and Korčula. The results of the research confirmed the initial hypotheses of the authors: young people are increasingly leaving Facebook as a “virtual promenade”, largely because older generations began using it, including their parents; they are mostly turning to social networks that offer a prevalence of photographs over text, primarily Instagram and Snapchat. In addition, no significant differences were found between members of generation Z in larger urban areas on the continent and smaller urban areas on the Adriatic islands, when it comes to their preferences.

Facebook has voyaged a significant distance since its launch in 2004 as a web-based social media connector. What initially started off as a way to socially associate people at an individual level has in its journey become a platform for doing business easily. It is currently a huge ring to associate and network across the globe. Sonia Konjeti Agarwal has weaved a comparable success story utilizing Facebook. Her story, like that of Facebook, started with a motive to socially connect people of a geographical area. She created a Facebook group for women in Pune and christened it PULA (Pune Ladies Association), which has now become a vibrant business platform. Research Questions: i. Social entrepreneurs are change agents. In the context of social entrepreneurship which is most important: initiation of an idea, transmission of idea or creating a sustainable impact? ii. Social media is a powerful tool for networking. How did PULA strategically leverage social media for real time interactions and entrepreneurial ventures? Link to Theory: This case draws linkage to Social Cognitive Theory. Social Cognitive theory depicts bidirectional character of causation where behavior, cognitive, emotional factors and environment persistently and jointly persuade each other. Role of the protagonist in creating an exciting platform for indigenous entrepreneurs through the path of social entrepreneurship is linked here. Phenomenon Studied: Social entrepreneurship is a promising field with diverse interpretations. As a social entrepreneur, Sonia’s efforts are directed towards strengthening the identity of indigenous entrepreneurs. She initiated small venture creations within social network. Growth of indigenous entrepreneurs ignites self dependency and magnetizes new investments. Success of the virtual community to hone entrepreneurial skills is studied. Case context - As a social entrepreneur, the protagonist used Facebook to create virtual community of indigenous (women) entrepreneurs. PULA enhanced visibility, reach, network and prominence of indigenous entrepreneurs at low cost. Opportunity to interact with buyers directly expanded vendor registration in the group. It also created level playing field for first generation entrepreneurs. Findings: This case depicts pragmatism of the social entrepreneur. PULA unified the virtual community and resources fostering entrepreneurship. This virtual community signifies uniqueness of domain, novel practices and policies. PULA was initially constituted for social networking. Gradually members discovered business opportunities. Efficacy of social media for virtual engagement and small venture creation resulted in financial independence for women. Status of women transitioned to indigenous entrepreneur from homemaker. Growth of indigenous entrepreneurs being contagious, a wave of first generation entrepreneurs was born. Discussions: PULA encouraged individuals hitherto in the veil of self imposed life situations to become entrepreneurs. Sonia was zealous about empowering women, to create opportunities for them to succeed and advance in lives. As a social influencer her actions are directed towards social well being. Her primary objective is to leverage the trust shown by two hundred forty-five thousand plus members and six thousand five hundred plus verified sellers. Non existence of tangible and quantifiable metrics for measuring the performance of the social entrepreneur creates a challenge. Sonia is exploring new social media engagement strategies for creating a sustainable virtual community.

This research analyzes the power of the Internet and social networks in the Arab uprisings. We are interested in learning about the contribution of communication technology in low advanced societies in conflict situations and the value of the network as a link between young people who supported the changes from abroad and those who were directly involved in protests. On the importance of technology as a virtual communication tool we have conducted a series of online interviews with 30 young people from Tunisia, Egypt and Libya living in Barcelona, Madrid and Santiago de Compostela during the development of the conflicts and who were involved in the Arab Spring though the network. The research findings in this study prove that virtual support for uprisings were not based on coordinated actions, and that it was simply a confluence of similar acts coinciding in time and on the same platforms. The Internet and social networks served as elements for supporting the process and as a counterbalance to official censorship and to governmentsupportive media, and were useful for overcoming the isolation of Arab society, in order to make the conflicts visible and to attract relevant support from abroad. But it also showed that the network had constraints in the face of the consolidated propaganda infrastructure which existed in each country. Esta investigación analiza el papel de Internet y de las redes sociales en las revueltas árabes. Interesa conocer la contribución de la tecnología a la comunicación en sociedades poco avanzadas en situaciones de conflicto y el valor de la Red como enlace entre los jóvenes que apoyaban los cambios desde el exterior y los que participaban directamente en las manifestaciones. Para conocer la importancia de la tecnología como instrumento de comunicación virtual se ha realizado una serie de entrevistas online a 30 jóvenes de Túnez, Egipto y Libia que vivían en Barcelona, Madrid y Santiago de Compostela durante el desarrollo de los conflictos y que han participado en la primavera árabe a través de la Red. Los resultados de esta investigación demuestran que los apoyos virtuales a las revueltas no estaban basados en acciones coordinadas, simplemente se trataba de una confluencia de actos similares que coincidían en el tiempo y en las mismas plataformas. Internet y las redes sociales funcionaron como elementos de apoyo al proceso y como contrapeso a la censura oficial y a los medios afines al régimen, y fueron útiles para superar el aislamiento de la sociedad árabe, para hacer visibles los conflictos y para conseguir apoyos relevantes en el exterior. Pero también se demostró que la Red tenía limitaciones frente a la consolidada infraestructura de propaganda que existía en cada país.

Crowd sensing is a perception mode that recruits mobile device users to complete tasks such as data collection and cloud computing. For the cloud computing platform, crowd sensing can not only enable users to collaborate to complete large-scale awareness tasks but also provide users for types, social attributes, and other information for the cloud platform. In order to improve the effectiveness of crowd sensing, many incentive mechanisms have been proposed. Common incentives are monetary reward, entertainment & gamification, social relation, and virtual credit. However, there are rare incentives based on privacy protection basically. In this paper, we proposed a mixed incentive mechanism which combined privacy protection and virtual credit called a blockchain-based location privacy protection incentive mechanism in crowd sensing networks. Its network structure can be divided into three parts which are intelligence crowd sensing networks, confusion mechanism, and blockchain. We conducted the experiments in the campus environment and the results shows that the incentive mechanism proposed in this paper has the efficacious effect in stimulating user participation.

Currently, local area network (LAN) is commonplace in the Nigerian tertiary institutions and can be a good platform for distributing and disseminating instructional materials. Thus, this paper proposes to improve the quality of academics through online provision of learning resources based on Free and Open Source Software (FOSS); wired and wireless access to contents; and availability of the system 24/7. The system is based on third party software or FOSS called phpBB and Windows 2003 Server Active Directory Services. Both are installed and configured on an intranet. It has a discussion forum which is accessed through Hypertext Transfer Protocol using a web browser; and directory services for files/folders upload and download based on a set of privilege levels in Discretionary Access Control List (DACL) as a way of improving security. The system leads to the development of a virtual campus in Covenant University. Also, it has helpedimprove the quality of teaching by making lecture notes availably on the intranet, lecturer/studentinteraction, accessibility to teaching materials and reduce student’s idle time. The system helps in no small measure to correct the problems plaguing the educational sector such as examination malpractice, decline standards of education and cultism, as students are gainfully engaged in academic and social activities. The creation of a virtual campus would enhance the level of e-participation, and e-readiness of the graduate for the employment market. In particular, it bridges the divide between the developed and the developing nations.

AbstractThe social media platforms have a growing importance in our lives since they are the places where we “showcase” our living experiences. They also reflect a variety of dimensions regarding our position in the virtual and physical social life. Both of these factors make people to play certain characters in the social arena. The Social Network is gaining more and more importance in today’s world and has a deeper impact on the society as to the traditional media. Social media enables identity expression, exploration, and experimentation; something natural for the human experience. It is the agencies in real life, which provide a source of names for different sectors, that inspire the internet communities and the interactions they make within themselves. It is essential to comprehend the motives of agencies to have an understanding of the group interactions on social platforms. The enable individuals present themselves to others and determine the way they would like to be perceives in addition to helping them connect and interact with people, and participate in the activities they wish. Communicating online offers many ways to connect with others: individuals may or may not use their real names, and they can open as many accounts as they want to. This study explores practical aspects of identity construction, relating to issues virtual communities and social media. It also analyzes the probable reasons that individuals feel the need to create a virtual identity for themselves as well as “the spiral of transformation”, that is, the creation period goes ahead of the internet to reach the real life. This study also aims at concentrating on the virtual communities appearing in the social networks while questioning their social and cultural qualities and values.

The purpose of this study is to explore the Instagram users’ behaviors since Instagram users are rapidly growing recently. This study is based on Bhattacherejee’s (2001) IS Continuance Model, and try to propose a behavioral scale for Instagram users. Then, providing a research model to explore the relationship between the reasons they used Instagram, attitude and future intention. There are two steps in this study; first, exploring the patters of Instagram users and building the behavioral scale. We take quantity methodology and in-depth interview since in-depth interview could help to find those constructs which are not found yet. Second, a survey was completed on university campus, and structure equation model method was applied in this study. Since majority of Instagram users are young generation, the study was aimed at college students. A university was selected for the participant, and stratified random sampling was adopted with two controlled variables (gender, and college). A total of 395 questionnaires were completed in the university. The findings indicated that the motivation of Instagram users were different from Facebook users. Based on the in-depth reviews, participants had two main reasons to addict with Instagram. One was for “interesting” and the other was for social bounds. For the theory based model, results showed mostly supporting the relationships. Results could also be applied for the related industries, for creating a marketing platform (e.g. Instagram) to promote new service or product. Nowadays, Instagram is newly virtual social media compare to Facebook, and the users’ behavioral patterns were different from them. Therefore, it is an essential issue should be focus for the society. Keywords: Social Network; IS Continuance Model; Instagram

The article is devoted to the challenges of modern online communication of people, which in recent years has spread around the world. The modern Internet has become a wide, integrating environment, full of useful and interesting things and at the same time rich in irritation, aggression, persecution. Both the positive and negative aspects of the network are constantly evolving, adding to the number of online dangers. One such threat is cyberbullying, which often takes place on the platforms of various social networks, is a real danger to the social and mental comfort of people, especially adolescents, who are often unable to distinguish between virtual and real features of communication. One of the effective means of preventing such threats is the acquisition by future psychologists of knowledge about the types of cyberbullying, its essence, the specification of the time spent by adolescents in a virtual environment, the risks of computer addiction, and so on. Emphasis is placed on mastering by future specialists domestic and foreign methods of recognizing various phenomena of cyberbullying, working with individual psychological factors, especially adolescents, preventing manifestations of aggression, cruelty, emotional imbalance in children’s communication in networks. The article, based on foreign and domestic scientific sources and research methods, identifies and describes the factors influencing future psychologists to prevent and alleviate the effects of cyberbullying in online communication of adolescents, recognizing the phenomena of cyber aggression, increasing resilience, educating emotional intelligence and communicative intelligence. This will provide professionals with a significant component of their competence.

In the context of the rapid development of the information environment, a person’s life path, identity, and the living space of an individual are not only presented in real life, but also in the virtual world, as well as in augmented reality. The mixing of virtual and real spaces cannot but affect the daily life of young people. This article attempts to describe and structure the elements of life models as fragments of a life scenario, broadcast through communities in social networks. The social network VKontakte has become a meaningful field for analysis as it is the most popular and frequently used online platform in the information space for the purpose of transmitting interesting and relevant information among Russian peers. The starting point of the study was the assumption that the content of social network posts describing the spheres of life can serve as a basis for building elements of life models broadcast on the Internet. The research consisted of several stages: preparatory (questioning young people about their preferred Internet content) and the main one (semantic and content analysis of the content of social networks). The sample of the preparatory stage was 110 respondents, the average age was 22 years (SD=2.8). The main sample consisted of over 200,000 posts from the top 20 social media communities (with an average of 4 million subscribers, with entertainment and non-themed content) over the past 2 years. With the help of special program codes and computer programs, the posts devoted to the most significant spheres of human activity were analyzed. It was found that the most popular marker words denoting areas of life in posts are work, relationships, and family. The data of automated semantic and content analysis showed that most often, through posts in communities, a model of an active and purposeful person is declared. This is an individual who is ready for action, flexible, mobile with respect to work and self-development, but conservative in regard to building family relationships. The results obtained confirm the assumption that the characteristics of the components of life models are presented most vividly in the posts of Internet communities, are actively broadcast and have their own characteristics. The results of the research data can contribute to the study of the main mechanisms of transmission between contemporaries of characteristics of behavior in real life, values and information through Internet content, as well as the work of practicing psychologists when referring to the profile on social networks or preferred client communities.

Beyond traditional places for exchanges within organizations (for example, ward or branch meetings), virtual communication forums give members of political parties an opportunity to express their opinions on line. The social network of the Parti Socialiste (PS) in France, the Coopol, was created on January 12, 2010, and seems to hold out new prospects for public debate. The mediated exchanges which took place on this platform have allowed us to analyze the political debate among activists between July and October 2011. The results are based on different types of data (statistical analysis of text, web surveys and qualitative interviews) gathered while observing the debate on the forum and through interviews with voters and activists. The rationale for the use of three different approaches is related to the fact that the article presents several studies that can be evaluated in their totality, but should be taken singly in each case. The information provided by this article makes it an important case study which explains in an empirical way the latest theoretical approaches within this research field.

Full textAbstract:
Care of the self, according to Michel Foucault, is the practice of coming back to one’s soul and construct the truth of self. While in ancient times, people cared for themselves by writing in hupomnemata, in our modern times, we use social network sites (SNSs) or social media. These digital platforms have provided users with many technological advantages to conduct the online care of self. Sharing a post, posting a status, tweeting a photo or video, replying to a friend’s comments, or revising stories stored in their virtual timeline is one of many self-care acts in a virtual space. However, these advantages of digital technologies accompany with the challenges of losing freedom or being supervized by algorithms whenever individuals engage in social media. This paper tries to answer the question that how modern practices of hupomnemata and care for self, are supported and manipulated by social media’s algorithms. The paper is expected to contribute a new understanding of the self and care for the self in contemporary social media engagement.

Abstract Data show that seven out of every ten adults, over the age of 50, own a smartphone, with one out of ten owning a tablet. While traditional activities dictate the use of technology among this cohort, there is growing evidence that adults similarly use devices to also manage their medical care and to learn online. This increase has guided scholars in recognizing the utility of technology from designing interventions to understanding how technology may serve as a barrier and/or facilitator to one’s general well-being. This symposium features four presentations from nationally recognized scholars that will expand traditional perspectives on technology use, and how it influences social ties among older adults. Dr. Charness will examine the population-level trends in social network use by aging adults and discuss a recent CREATE intervention study (PRISM), that used a computer-based platform to reduce social isolation and loneliness among older adults. Dr. Czaja will similarly present findings from CREATE, and other trials, on the access to and use of email, social media sites, and online support groups among older adults, and the resultant impact on social connectivity, loneliness and social support. Dr. Rogers will discuss technologies that currently exist (e.g., apps, mobile devices, social networking) or are being developed (e.g., robotics, telepresence, virtual reality) to support social engagement. Dr. Antonucci will examine aspects of new technologies and their influence on health and well-being, while underscoring the perspective that new and emerging technologies hold great promise in overcoming traditional barriers to maintaining social contact and exchange.

Full textAbstract:
This study was conducted to investigate English for Specific Purposes (ESP) learners’ experiences in using social learning network sites, namely Edmodo in a virtual community of practice environment. This study was also aimed to identify the challenges that the learners encountered in using Edmodo. Mixed-method research was employed to collect the data for this study; a questionnaire survey and a focus group discussion. The collected data was analysed through statistical and thematic analysis. The results showed that most of the ESP learners were of the opinion that Edmodo was effective as a platform for a virtual community of practice, particularly in terms of interaction and knowledge sharing. The findings also revealed that some learners have had difficulties in creating a social identity in the community because of the lack of collaboration among the team members. Therefore, it is suggested that genuine, consistent, and synergistic motivation from educators followed by the active involvement of learners will surely boost the engagement of peripheral participants in the community. This study is significant as it offers some insights into how ESP practitioners and learners use social learning networks in building an effective ESP virtual learning community to achieve the learning outcome of the ESP course.

Full textAbstract:
This work is part of an ongoing research project to develop an unmanned flying social robot to monitor dependants at home in order to detect the person’s state and bring the necessary assistance. In this sense, this paper focuses on the description of a virtual reality (VR) simulation platform for the monitoring process of an avatar in a virtual home by a rotatory-wing autonomous unmanned aerial vehicle (UAV). This platform is based on a distributed architecture composed of three modules communicated through the message queue telemetry transport (MQTT) protocol: the UAV Simulator implemented in MATLAB/Simulink, the VR Visualiser developed in Unity, and the new emotion recognition (ER) system developed in Python. Using a face detection algorithm and a convolutional neural network (CNN), the ER System is able to detect the person’s face in the image captured by the UAV’s on-board camera and classify the emotion among seven possible ones (surprise; fear; happiness; sadness; disgust; anger; or neutral expression). The experimental results demonstrate the correct integration of this new computer vision module within the VR platform, as well as the good performance of the designed CNN, with around 85% in the F1-score, a mean of the precision and recall of the model. The developed emotion detection system can be used in the future implementation of the assistance UAV that monitors dependent people in a real environment, since the methodology used is valid for images of real people.

Purpose – Social media platforms established social relationship between the consumer and the brand community. The purpose of this paper is to propose a model to understand how dual-identification impact on the community citizenship behavior (CCB). Specifically, the authors propose perceived community-brand similarity (PCBS) influence CCB via dual-identification and brand passion (BP). Design/methodology/approach – The research sample consists of 323 members who have used Apple product and used Apple fan page for more than one year, and structural equation modeling was used to test the research hypotheses. Findings – The results indicated that PCBS directly influenced brand identification (BI) and community identification (CI), respectively. BI directly influenced CI. CI directly influenced BP, but BI not directly influenced BP. In the mediation effects, both the dual-identification factors and BP play important mediating roles. Practical implications – From a managerial standpoint, this research provides implications for social network sites management. Originality/value – This research fills a void in the BI and CI are coexisting but distinct aspects of virtual communities. In addition, the mediating role of dual-identification factors and BP in the online community consumer-brand relationship has not been fully investigated.

AbstractAchieving greener cloud computing is non-negligible for the open-source cloud platform. In this paper, we propose a novel virtual machine allocation scheme with a sleep-delay and establish a corresponding mathematical model. Taking into account the number of tasks and the state of the physical machine, we construct a two-dimensional Markov chain and derive the average latency of tasks and the energy-saving degree of the system in the steady state. Moreover, we provide numerical experiments to show the effectiveness of the proposed scheme. Furthermore, we study the Nash equilibrium behavior and the socially optimal behavior of tasks and carry out an improved adaptive genetic algorithm to obtain the socially optimal arrival rate of tasks. Finally, we present a pricing policy for tasks to maximize the social profit when managing the network resource within the cloud environment.

Full textAbstract:
Virtual reality (VR) uses sensorial mimetics to construct collective memory in virtual space. The regeneration of high-definition cultural heritage symbols transforms memory into an immediate experience that is constantly being renewed, strengthens the relationship between cultural heritage and contemporary society, and continually affects the persistent renewal of cultural traditions. Hyper-presence is a networked state of cognitive psychology that lies in links, interactions, and exchanges; it is the result of networked social minds and distributed cognition. In the contemporary moment, cultural heritage takes on three types of progressively developed presence: simulated restoration presence, informationally reproduced presence, and symbolically regenerated presence. Symbolic regeneration belongs to the realm of hyper-presence. Building databases with data collected on cultural heritage is the foundation of building a cognitive agent. As a platform, VR becomes an efficient mode of information dissemination, forming an independent presence for cultural heritage through the reproduction of media and information. In a network society, informatized cultural heritage becomes a source for the production of new cultural symbols, and presence is created through the continuous regeneration and dissemination of symbols. Symbols and regenerated symbols combine to constitute the hyper-presence of informatized cultural heritage; people's understanding of cultural heritage therefore exists in an ever-changing state. Intelligences with presence on the network form a complete system, and VR creates comprehensive cognition for the system through high-definition virtuality. Formed in the coordination between intelligences, collective memory creates its hyper-presence today.

Full textAbstract:
Whether dealing with social work, humanitarian assistance, solidarity or cooperation, the multilingual linguistic resources necessary for supporting social mediators within the domain of humanitarian work are significantly lacking. Institutional infrastructures which could be capable of fulfilling these needs end up being excessively rigid and sluggish in responding to the complex linguistic situations in which people in vulnerable circumstances find themselves immersed. As such, in times of need and of assistance following a natural disaster, or as a consequence of armed conflict or due to reasons of social injustice, the traditional, linear and hierarchical processes of terminology production prove inadequate when the tools critical for dealing with urgent situations must be provided. Unlike the methods typically used in industrial societies, the “network society” proposes new models of collaborative work patterned on virtual communities. This article takes as its premise that the hacker spirit, a key aspect of the “network society” (Castells 2011), is an exceptional point of reference around which new processes for terminology work can be developed. The goal of the article is to explore this terrain and show how these ideas have actually been implemented in practice through the creation of the collaborative platform Humanterm.

Smartphones are becoming  a dominant form of mobile computing in the world. The Smartphone, as a platform, blends a traditional general computing platform with a specialized mobile phone platform. The general computing tradition is historically open, allowing its owners to install whatever software they choose and to add or remove hardware as they please. Also they are a vault for large amount of personal information about banking, social network, and inter-personal communication. These capabilities and information value make it an attractive target to internet miscreants.This paper presents a survey on recent researches in Smartphone honeypot. Physical and virtual honeypots have been studied in details; however, there is only little work in the field of mobile related honeypot. The survey presents the challenges while setting up a smartphone honeypot, and summarizes the researches published in this area. We clarify the methods used to build their honeypot, and the results they obtained and their recommendations.

A agricultura familiar representa um segmento de grande importância econômica e social para o meio rural brasileiro. Devido a essa importância, observa-se um crescente interesse do governo por esse segmento, que se materializa em forma de políticas públicas. Dessa forma, em 2011, o Ministério do Desenvolvimento Agrário (MDA) criou o Programa Rede Brasil Rural, uma ferramenta virtual que visa facilitar o contato entre as cooperativas e associações de produtores rurais e os fornecedores de insumos, a logística de transporte e os consumidores públicos e privados. O principal objetivo da rede é auxiliar na comercialização, seja dos insumos necessários à produção, seja dos produtos procedentes da agricultura familiar através de uma plataforma eletrônica. O propósito do Programa Rede Brasil Rural é inserir novos conceitos e ampliar o limite geográfico de comercialização para o segmento através do comércio eletrônico. O objetivo desse estudo é escrever os mecanismos de funcionamento da Rede Brasil Rural, as medidas adotadas pelo governo para implantação do programa, os principais parceiros, as Contribuições que a rede proporcionará à agricultura familiar, além dos desafios a serem superados. Rural Brazil Net Work: Innovation Within The Family Agriculture Context ABSTRACT: Family agriculture is a segment of high economic and social importance for the Brazilian rural region. There is an increasing interest by the government manifested in public policies. The Ministry of Agrarian Development established in 2011 the Rural Brazil Network Program, a virtual tool that facilitates contact between cooperatives and associations of rural producers, suppliers, transport logistics and public and private consumers. The network´s main aim is the commercialization of required production supplies and of products produced by family agriculture through an electronic platform. Rural Brazil Network Program inserts new concepts and amplifies the geographical limit of commercialization for the segment through electronic commerce. Current analysis describes the functioning of the Rural Brazil Network Program, the measures worked by the government to adopt the program, the main partners, the contributions that the network provides to family agriculture and the challenges that should be coped with.

In 2017 the company Epic Games created the videogame Fortnite. This game has become the cross-platform survival and open experience with the greatest penetration worldwide. The rapid increase of use has spread alarm voices among parents and the media have echoed these concerns criticizing the game for being responsible for most afflictions suffered by children and adolescents. 178 The study is based on an understanding of the game as a key element in personal and social development. Therefore, this project aims to explore and describe the specific interactions emerging as a result of the penetration of Fortnite into family life, seeking to extend our understanding of the phenomenon and the potential effects that it may produce in the family dynamics. The research also seeks to categorize the dynamics generated, emphasizing more specifically on implications for parents in terms of educative mediation. Concerning the methodology, this is a qualitative exploratory case study, in which observations and in-depth interviews are the main sources of data collection. According to the analysis of the first interviews and observations, it is possible to provisionally hypothesize that, unlike simplistic views spread through mass media of Fortnite as a new dangerous addictive platform for young people, the diverse contexts and realities that configure each family make this type of linear interpretations highly problematic. Most technological devices affect the interaction and relational dynamics already installed in families. Throughout the last forty years, television and offline video games have been playing a significant role in shaping the family relationships. Online environments today increase such influence. The complex interrelations generated in blended social ecosystems, such as 'what is' or 'what is not' permitted, the mechanism of videogame banning or use as a form of punishment or reward, the myths, and ignorance on the part of adults concerning the ‘virtual’ socialization of youth and the relevance of this practice among young people, are some of the contributions that can be drawn from this investigation. This presentation exposes the collaborative work conducted by researchers of Universidad Austral (Argentina) and Universidad de los Andes (Chile), which has gained the first place in the award provided by the Network of Latin American University Institutes of Family (REDIFAM).

Aiming at the problems in the social governance structure level under the management mode of the Internet of Things, this paper designs a network agent based on the idea of service grid construction that has the functions of service resource configuration discovery, load balancing, and protocol conversion. Using it as a service governance infrastructure reduces the coupling between business services and service governance, and the network agent will intercept the service call traffic within the platform to achieve cross-protocol and cross-frame service communication. Through the proposed global query decomposition strategy and algorithm, a global query mapping is realized, which solves the problem of global query decomposition based on the global data model. We designed the unified management mechanism of two commonly used IoT databases based on XML. This process involves the realization of heterogeneous Internet of Things database resource configuration, data mode conversion, and global query mapping. Among them, in the process of data schema conversion, the conflict of the data in the schema mapping is resolved, the XML Schema is generated, the schema mapping metadata is established, and the XML document of the data is generated. We build a framework for optimal allocation of cloud computing resources based on load forecasting and propose an adaptive elastic control system for resource allocation based on resource status monitoring and demand forecasting. In view of the low resource utilization problem caused by the resource management mode of single virtual machine serving single user adopted by Internet of Things service providers, this paper constructs a new public cloud architecture with a five-layer structure. On the basis of this architecture, an adaptive configuration mode of virtualized resources based on a single virtual machine serving multiple users is proposed. This mode can automatically search for optimal virtualization resources for application resource requests made by different users and run different applications on the same virtual machine without affecting the quality of service, so that IoT providers can guarantee services. At the same time, it improves the utilization efficiency of IoT resources and reduces energy consumption.

This paper contributes to the state of the art of applications of artificial intelligence (AI) in energy systems with a focus on the phenomenon of social acceptance of energy projects. The aim of the paper is to present a novel AI-powered communication and engagement framework for energy projects. The method can assist project managers of energy projects to develop AI-powered virtual communication and engagement agents for engaging their citizens and their network of stakeholders who influence their energy projects. Unlike the standard consultation techniques and large-scale deliberative engagement approaches that require face-to-face engagement, the virtual engagement platform provides citizens with a forum to continually influence project outcomes at the comfort of their homes or anywhere via mobile devices. In the communication and engagement process, the project managers’ cognitive capability can be augmented with the probabilistic capability of the algorithm to gain insights into the stakeholders’ positive and negative feelings on the project, in order to devise interventions to co-develop an acceptable energy project. The proposed method was developed using the combined capability of fuzzy logic and a deep neural network incorporated with a Likert scaling strategy to reason with and engage people. In a mainstream deep neural network, one requires lots of data to build the system. The novelty of our system, however, in relation to the mainstream deep neural network approach, is that one can even use small data of a few hundreds to build the system. Further, its performance can be improved over time as it learns more about the future. We have tested the feasibility of the system using citizens’ affective responses to CO2 storage and the system demonstrated 90.476% performance.
