    This paper explores the intrapersonal and interpersonal motivations involved in the playing of MMORPGs, and the impacts of gaming on online and offline relationships. Twenty-one participants completed an online synchronous interview in which they discussed their personal experiences of playing MMORPGs. An online survey was then developed to further explore the findings of the interviews and this was completed by 52 participants. A content-analysis of the interview transcripts showed that interpersonal factors (such as social communication and group cohesion) were the strongest motivators for game-playing, supporting previous research [1]. The interview data also showed that there tended to be conflict, rather than integration, between online and offline relationships, however the questionnaire data showed the opposite. This was a small-scale pilot study and a further larger study is planned which will investigate whether Social Identity Theory can be used to explain players’ perceptions of group and personal identity

    Health Research Access to Personal Confidential Data in England and Wales: Assessing any gap in public attitude between preferable and acceptable models of consent

    England and Wales are moving toward a model of ‘opt out’ for use of personal confidential data in health research. Existing research does not make clear how acceptable this move is to the public. While people are typically supportive of health research, when asked to describe the ideal level of control there is a marked lack of consensus over the preferred model of consent (e.g. explicit consent, opt out etc.). This study sought to investigate a relatively unexplored difference between the consent model that people prefer and that which they are willing to accept. It also sought to explore any reasons for such acceptance. A mixed methods approach was used to gather data, incorporating a structured questionnaire and in-depth focus group discussions led by an external facilitator. The sampling strategy was designed to recruit people with different involvement in the NHS but typically with experience of NHS services. Three separate focus groups were carried out over three consecutive days. The central finding is that people are typically willing to accept models of consent other than that which they would prefer. Such acceptance is typically conditional upon a number of factors, including: security and confidentiality, no inappropriate commercialisation or detrimental use, transparency, independent overview, the ability to object to any processing considered to be inappropriate or particularly sensitive. This study suggests that most people would find research use without the possibility of objection to be unacceptable. However, the study also suggests that people who would prefer to be asked explicitly before data were used for purposes beyond direct care may be willing to accept an opt out model of consent if the reasons for not seeking explicit consent are accessible to them and they trust that data is only going to be used under conditions, and with safeguards, that they would consider to be acceptable even if not preferable

    New VLBA Identifications of Compact Symmetric Objects

    Get PDF
    The class of radio sources known as Compact Symmetric Objects (CSOs) is of particular interest in the study of the evolution of radio galaxies. CSOs are thought to be young (probably ~10^4 years), and a very high fraction of them exhibit HI absorption toward the central parsecs. The HI, which is thought to be part of a circumnuclear torus of accreting gas, can be observed using the VLBA with high enough angular resolution to map the velocity field of the gas. This velocity field provides new information on the accretion process in the central engines of these young sources. We have identified 9 new CSOs from radio continuum observations for the VLBA Calibrator Survey, increasing the number of known CSOs by almost 50%.Comment: 5 pages, 2 figures, for "Lifecycles of Radio Galaxies", eds.

    Quasiconformal homogeneity after Gehring and Palks

    In a very influential paper Gehring and Palka introduced the notions of quasiconformally homogeneous and uniformly quasiconformally homogeneous subsets of Euclidean space. Their motivation was to provide a characterization of quasi-disks, i.e. domains which are quasiconformally homeomorphic to the unit disk. As a generalization, Bonfert-Taylor, Canary, Martin and Taylor initiated the study of uniformly quasiconformally homogeneous hyperbolic manifolds. In this paper, we review the theory of quasiconformally homogeneous subsets of Euclidean and uniformly quasiconformally homogeneous hyperbolic manifolds. We finish with a discussion of open problems in the theory.Comment: To be published in a volume of Computational Methods and Function Theory dedicated to the memory of Fred Gehrin

    SAMP, the Simple Application Messaging Protocol: Letting applications talk to each other

    Full text link
    SAMP, the Simple Application Messaging Protocol, is a hub-based communication standard for the exchange of data and control between participating client applications. It has been developed within the context of the Virtual Observatory with the aim of enabling specialised data analysis tools to cooperate as a loosely integrated suite, and is now in use by many and varied desktop and web-based applications dealing with astronomical data. This paper reviews the requirements and design principles that led to SAMP's specification, provides a high-level description of the protocol, and discusses some of its common and possible future usage patterns, with particular attention to those factors that have aided its success in practice.Comment: 12 pages, 3 figures.

    Unification Achieved: William Cullen’s Theory of Heat and Phlogiston as an example of his Philosophical Chemistry

    Get PDF
    William Cullen, lecturer in chemistry at Glasgow and Edinburgh Universities, spent many years formulating his own theory of heat and combustion, the most developed version of which appears in a little-known set of lecture notes of 1765. Cullen's theory is of particular interest to historians of chemistry as an example of his ideal of ‘philosophical chemistry’, an autonomous branch of natural philosophy distinct from the mechanical philosophy, with its own general laws and explanations of phenomena justified by observation. The theory assimilated Joseph Black's recent discovery of fixed air as well as Cullen's investigations of the generation of heat in chemical operations. It was formulated just one year before British chemists' sudden identification of new ‘airs’ was dramatically to change the field of phlogiston theory. The theory differs in important ways from any version yet discussed. It successfully brought both heat and elective attraction within its explanatory domain. It set out a causal hierarchy which reversed the usual pattern evinced in earlier sets of lecture notes, subordinating the mechanical to the chemical in the form of Cullen's theory of elective attraction. The paper argues that Cullen was attempting to bring the study of heat as well as combustion within the bounds of his ‘philosophical chemistry’ by means of his single unifying theory

    Flipping great or flipping useless? a review of the flipped classroom experiment at Coventry University London Campus

    Get PDF
    It is vital for teachers to keep abreast of new innovations to maintain student expectations and continuously improve performance in the classroom. A major development in recent pedagogical practice has seen the invention, development and implementation of the flipped classroom. Advantages include greater flexibility for students as they can study at their own leisure. In addition, there are opportunities for teachers to make seminars more interactive and to focus on exploring topics in greater depth after fundamental concepts have been practiced in a flipped class. This scenario has also led to greater student engagement and motivation and reduced tardiness and attendance issues. However, there are several disadvantages regarding its use. The most prominent criticism is that it is not possible to ascertain if a student has actually completed a flipped class until they attend a seminar. The whole flipped model is also wholly reliant on students having the motivation to do work in their own time. The creation, development and implementation of flipped classes can also be labour-intensive and onerous for teachers with already busy schedules. Further criticisms include the lack of instructor contact and necessity for developers to possess requisite technological skills. This study uncovered both positives and negatives regarding its efficacy with a number of students doubting its value in enhancing academic standards. Overall student performance and satisfaction levels were also lower when compared to the previous term when the same module was not flipped
