This paper examines Bitcoin from a legal and regulatory perspective, answering several important questions.We begin by explaining what Bitcoin is, and why it matters. We describe problems with Bitcoin as a method of implementing a cryptocurrency. This introduction to cryptocurrencies allows us eventually to ask the inevitable question: is it legal? What are the regulatory responses to the currency? Can it be regulated?We make clear why virtual currencies are of interest, how self-regulation has failed, and what useful lessons can be learned. Finally, we produce useful and semi-permanent findings into the usefulness of virtual currencies in general, blockchains as a means of mining currency, and the profundity of Bitcoin as compared with the development of block chain technologies. We conclude that though Bitcoin may be the equivalent of Second Life a decade later, so blockchains may be the equivalent of Web 2.0 social networks, a truly transformative social technology.

Recently, Web 2.0 applications such as blogs, wikis (e.g., Wikipedia), social networks (e.g., MySpace), 3-D virtual worlds (e.g., Second Life), and so forth, have created fresh interest in the Internet as a new medium of social interactions and human collaborative activities. Since the emergence of Web 2.0 applications, Web services that support online human activities have gained an unprecedented boost. There have been conceptual studies on and overviews of individual Web 2.0 applications like blogs, online social networks, and so forth, but there has not been a study to date which provides a theoretical perspective on the online human activity networks (OnHANs) formed by these Web 2.0 applications. In this chapter, we classify various forms of OnHANs focusing on their social and business purposes, analyzing the core components of representative OnHANs from the angle of the activity theory, and finally providing a theoretical discussion concerning how OnHANs provide values to the individuals and the organizations involved in those activities.

Web 2.0 offers the Zeitgeist to update seminal research concerning children's Private Speech (PS) and Self-Regulation Learning (SRL) for application in social networks. Contemporary literature holds a body of research from the Vygotsky through Piaget to constructive theories that can be applied to theoretical foundations of Web 3.0 designs. Specifically, the purpose of the present chapter is to be present an index based on valuable and effective research concerning the subject matter in which a historical overview of both PS and SRL have demonstrated significant complexities and the most significant critiques that exist in the literature. The chapter does not mean to include detailed research methodology and results but, instead, to be used as an indexing review of PS and SRL for possible theoretical foundations in applications in the expanding world of social media. Finally, the conclusion provides a reflection on the future of our children's PS and SRL and what we should do next to enhance these concepts.

ABSTRACTThis paper presents the main results of an investigation whose purpose is to investigate the adoption of on-line social networks in SMEs run by women. The base assumption is that the use of networks as a strategic communication element is still at an early stage of development, far from being an established practice. Our interest in this study is to determine the willingness and motivations of entrepreneurs in using these networks, as well as utilities and difficulties they have faced. Our goal is to visualize the change of attitude and competences that entrepreneurs are imprinting on their businesses within the competitive environment they operate in. Ultimately, we are interested in studying the perception of women-entrepreneurs regarding the adoption of online social networks to the extent where they are, as an additional management tool. We find ourselves facing a new field of knowledge on which there are very few references and very little research has been carried. Hence, this study has a primarily qualitative and exploratory purpose. To obtain the needed information we held semi-structured interviews to fourteen Andalusian entrepreneurs, coming from different business fields. The main findings were that just less than a half of them used them, or implemented them in their companies, as communication tools. The others, depending on to the size of their business, adopted them as an extension of the personal use in which they had been started.RESUMENEste trabajo presenta los principales resultados de una investigación cuya finalidad es conocer la adopción de las redes sociales on-line en las pymes dirigidas por mujeres. Se parte de la base de que el uso de redes, como elemento estratégico de comunicación, se encuentra todavía en una fase incipiente de desarrollo, lejos aún de ser una práctica consolidada. Nuestro interés en este trabajo es conocer la predisposición y motivaciones de las empresarias hacia el uso estas redes, así como las utilidades y dificultades a las que han de enfrentarse. Nos interesa visibilizar el cambio actitudinal y competencial que las empresarias están imprimiendo en sus empresas dentro del marco competitivo en el que se encuentran. En definitiva, nos interesa estudiar la percepción que tienen las empresarias sobre el uso de las redes sociales online en la medida en que están insertas, como una herramienta más de gestión empresarial. Nos situamos ante un nuevo ámbito de conocimiento sobre el que apenas existen referencias bibliográficas ni se ha realizado apenas investigación; de ahí que la investigación tenga una finalidad fundamentalmente exploratoria y de carácter cualitativo. Para la obtención de la información se realizaron catorce entrevistas semi-estructuradas entre empresarias andaluzas de distintos sectores de actividad. Entre los principales resultados encontramos que algo menos de la mitad de ellas las utilizan, o están implantadas en sus empresas, como herramientas de comunicación. El resto, y relacionado con el tamaño de sus negocios, las utilizan como una prolongación del uso personal en el que se iniciaron.

This investigation aimed to determine the use of web 2.0 services in the Catholic University Cecilio Acosta (UNICA) site by the institution, located in Maracaibo city, Venezuela. The theoretical contributions were supported by O'Reilly (2007), Lévy (2004), Rheingold (2004), Surowiecki (2005), Cobo (2007a), among other authors. The investigation comes from a project attached to the UNICA Research and Postgraduate Deanery, was descriptive, an observation guide was applied to collect information from the UNICA website and the 2.0 services to which it is associated as the platforms for vertical social networks YouTube, Instagram and SoundCloud, and platforms for horizontal social networks Facebook and Twitter. Among the most relevant findings was the exclusive use of social networking services for interaction with the university community, without including other services that seek to generate knowledge. It is concluded that UNICA uses web 2.0 services in its site in a limited and non-strategic way, with a purely informative nature that includes specific topics of the university and the catholic church, which could hinder the knowledge management as process of 21st century universities.

Inspired by infectious disease dynamics and modern psychology, this paper aims at constructing a multi-dimensional function to get the model of information dissemination on social networks under epidemic-related panic base on the characteristics of individual differences and global characteristics, like emotional cumulative effect, herd effect, time-sensitive decline effect, cognitive level, intimacy, personal influence, etc. The results show that the psychological effect has a significant effect on the increase of the spread of panic news; When netizens are in an emotional atmosphere, their emotional self-regulation ability is limited; when the infection rate is relatively low, the characteristics of individual differences play a leading role in affecting the spreading process. When the infection rate is high enough, the herd effect and emotional cumulative effect play a major role in promoting information dissemination; In a society with a higher rate of emotional contact, it is easier to form a kind of collective wisdom, which can help the collective quickly identify rumors. Moreover, in this kind of society, the role of opinion leaders is limited, and timely refutation of rumors can significantly reduce the spread of panic news.

Migraine is the second leading cause of maladjustment, and the burden of migraine is determined by its impact on work ability, social activity and family relationships.Objective: to identify the patterns of behavior of Russian patients with migraine, factors affecting their quality of life, and the level of awareness of the disease based on a semantic analysis of messages in Web 2.0.Patients and methods. The study is based on the results of semantic processing (automated analysis of natural language texts, taking into account their meaning) of anonymized messages from 6566 unique authors (patients and their relatives) from social networks and forums (over 73 thousand messages over 10 years, 2010–2020). In addition, the study was carried out exclusively according to the data indicated in the messages. In this regard, complete data for several parameters was not available for analysis. No personal data about the authors of the messages was collected or used. The sex was determined based on the text of the analyzed message. For the study, only open data from the Internet from social networks and forums was used.Results and discussion. A landscape of problems of persons complaining of migraine issues was formed. Factors affecting the quality of life were grouped into four main groups (“Lifestyle restrictions by triggers of migraine attacks”, “Loss of opportunity to work”, “Serious psychological problems”, “Family planning issues”); additional, rarer, but acute problems were also identified. The analyzed messages show that the average number of days with migraines is 9.4 per month; 21.8% of patients report daily migraines. Moreover, most patients have been suffering from attacks for 10 years or more, and 9% of patients – for 30 years or more. The analysis of diagnostic patterns showed that in most cases, patients independently resorted to additional examination methods, while only 13.1% of patients had experience of adequate preventive therapy.Conclusion. The study demonstrated the presence of a wide range of unmet needs, quality of life problems both in patients themselves and their caregivers, as well as a significant social and economic burden of this disease (including a long-term burden on the economy, which can be used as arguments for reimbursing the cost of migraine therapy) based on the text messages on migraine in open sources on the Internet.
