THE NECESSITY OF DEVELOPING RESPONSIBLE USE POLICIES: ADVOCACY FOR USE OF WEB 2.0 TOOLS IN A COMPREHENSIVE SCHOOL COMPUTING PROGRAM

Technology is omnipresent in our modern age: anyone with an Internet connection can use a computer, tablet, or phone to access an unfathomable amount of information. Today, teenagers use e-mail, texting, and social media to stay in nearly constant communication with friends and family anywhere in the world. With so much time spent exchanging ideas in cyberspace, there is an increased likelihood of teachers and students regularly crossing paths electronically for both legitimate academic purposes and social contexts. Without sufficient school district policies to guide these interactions, students and teachers could realistically place themselves in awkward situations and face district sanctions due to inappropriate behavior. The purpose of this project is to develop an Acceptable Use Policy (AUP) governing student and teacher computer use that must be reviewed and signed by parents, students, and teachers at the start of every school year. The policy advocacy focuses on inclusion of social media and other Web 2.0 tools as legitimate applications for the classroom. Research provides valuable information regarding responsible ways to utilize Web 2.0 tools to enhance teaching and learning and incorporate them into a school’s repertoire of instructional methodologies. These technologies tap into students’ inherent interests, create opportunities for active learning and higher-order thinking, and prepare students for the challenges of tomorrow’s workplace. However, schools also need to protect students against cyberbullies, online predators, and exposure to inappropriate content. The project concludes that allowing Web 2.0 tools into classrooms while developing responsible computing skills across the curriculum outweighs any perceived risks. The proposal outlines an adoption plan that factors in educational activities, staff development, budget, and progress monitoring

Individual popularity and activity in online social systems

We propose a stochastic model of web user behaviors in online social systems, and study the influence of attraction kernel on statistical property of user or item occurrence. Combining the different growth patterns of new entities and attraction patterns of old ones, different heavy-tailed distributions for popularity and activity which have been observed in real life, can be obtained. From a broader perspective, we explore the underlying principle governing the statistical feature of individual popularity and activity in online social systems and point out the potential simple mechanism underlying the complex dynamics of the systems.Comment: 7 pages, 7 figures, 1 table, accepted for publication in Physica

Some ethical and legal considerations in the use of Web 2.0

This chapter explores ethical and legal issues that need to be considered by health information professionals when using Web 2.0 technologies. It reviews how the Internet and the Web have affected standards of professional behaviour, and highlights the problems that result when legal frameworks lag behind a rapidly developing technology. It discusses the need for appropriate forms of risk assessment with particular reference to issues of defamation, data protection, and intellectual property rights.

Social Media in the Dental School Environment, Part A: Benefits, Challenges, and Recommendations for Use

Social media consist of powerful tools that impact not only communication but relationships among people, thus posing an inherent challenge to the traditional standards of who we are as dental educators and what we can expect of each other. This article examines how the world of social media has changed dental education. Its goal is to outline the complex issues that social media use presents for academic dental institutions and to examine these issues from personal, professional, and legal perspectives. After providing an update on social media, the article considers the advantages and risks associated with the use of social media at the interpersonal, professional, and institutional levels. Policies and legal issues of which academic dental institutions need to be aware from a compliance perspective are examined, along with considerations and resources needed to develop effective social media policies. The challenge facing dental educators is how to capitalize on the benefits that social media offer, while minimizing risks and complying with the various forms of legal constraint

Characterizing and Modeling the Dynamics of Activity and Popularity

Social media, regarded as two-layer networks consisting of users and items, turn out to be the most important channels for access to massive information in the era of Web 2.0. The dynamics of human activity and item popularity is a crucial issue in social media networks. In this paper, by analyzing the growth of user activity and item popularity in four empirical social media networks, i.e., Amazon, Flickr, Delicious and Wikipedia, it is found that cross links between users and items are more likely to be created by active users and to be acquired by popular items, where user activity and item popularity are measured by the number of cross links associated with users and items. This indicates that users generally trace popular items, overall. However, it is found that the inactive users more severely trace popular items than the active users. Inspired by empirical analysis, we propose an evolving model for such networks, in which the evolution is driven only by two-step random walk. Numerical experiments verified that the model can qualitatively reproduce the distributions of user activity and item popularity observed in empirical networks. These results might shed light on the understandings of micro dynamics of activity and popularity in social media networks.Comment: 13 pages, 6 figures, 2 table

The Open Society and coach education: a philosophical agenda for policy reform and future sociological research

Background: The realisation of the strategic importance of high quality coaching to the achievement of national sport policy objectives is resulting in extensive movements to professionalise the coaching industry. Interest in coach education is therefore growing among academics and policy-makers alike. A recent review of literature in this field, however, reveals a troubling problem situation: formal coach education is important for coach learning but tends to be expensive, inflexible and overly technical and therefore has little real impact on coaching practice. The solutions offered by many academics are, unfortunately, vague and often philosophically flawed. This is particularly so when the descriptive model of communities of practice (CoP) is suggested as a prescriptive model for coach education. The first part of the paper, therefore, ends with an extended critique of the use of CoP as a model for coach education. Purpose: To provide a clear philosophical argument for the direction of reform for coach education, drawing on a normative theory of the ideal conditions for the growth of knowledge. Discussion: Starting with the argument that any descriptive (or ‘evidence-based’) model is inherently conservative, the second part of the paper offers an alternative solution to the problem of coach education that is openly prescriptive (or normative). It is the Popperian ideal type of an Open Society (OS). It is argued that the concept of an OS is a better prescriptive model for coach learning for a number of reasons. First, it is based on a logically sound epistemological theory of the ideal social conditions for the growth of knowledge. Second, it is simple and easy for lay people to understand. Third, as an ideal type, it offers a target or goal against which progress towards a better method of coach education can be measured. In this final sense, it also offers a clear agenda for policy reform and future sociological research. Conclusions: The paper makes a series of practical recommendations for reforming coach education and its institutions based on the model of the OS. Foremost among these are making learning resources free at the point of use and using Web 2.0 technologies to democratise educational episodes and widen participation in coach education programmes of all kinds

Vortex-type elastic structured media and dynamic shielding

The paper addresses a novel model of metamaterial structure. A system of spinners has been embedded into a two-dimensional periodic lattice system. The equations of motion of spinners are used to derive the expression for the chiral term in the equations describing the dynamics of the lattice. Dispersion of elastic waves is shown to possess innovative filtering and polarization properties induced by the vortextype nature of the structured media. The related homogenised effective behavior is obtained analytically and it has been implemented to build a shielding cloak around an obstacle. Analytical work is accompanied by numerical illustrations.Comment: 24 pages, 13 figure
