The Mainstreaming of Verbally Aggressive Online Political Behaviors

The purpose of this paper was to investigate the relationship between verbal aggression and uncivil media attention on political flaming. More specifically, this paper examines whether the use of uncivil media programming is associated with the perceived acceptability and intention to engage in aggressive online discussions (i.e., online political flaming) and whether this relationship varies by verbal aggression. The results show that individuals less inclined to engage in aggressive communication tactics (i.e., low in verbal aggression) become more accepting of flaming and show greater intention to flame as their attention to uncivil media increases. By contrast, those with comparatively higher levels of verbal aggression show a decrease in acceptance and intention to flame as their attention to these same media increases.Advertisin

Bakelite and other Shibboleths: eBay listings and the 'policing' of 'amateur' collecting knowledges within the space of an online old radio forum

eBay, the online auction site, is composed of thousands of item descriptions constructed by sellers themselves. Sellers may be collectors or antiques experts, but often they are amateurs selling off unwanted items. As such, eBay becomes an unprecedented public space for the performance of amateur collecting and consumption knowledges where experts are being disintermediated by non-expert knowledges. These knowledges have become a major source of discussion on an online old radio discussion forum and the case study presented here contends that amateur knowledges are strongly contested, often in separate online spaces, and as part of identity performance. While a ‘cult of the amateur’ may be occurring online, it is not happening without a fight over knowledge and its performance. eBay is shown as a relational space to the forum, allowing radio experts to perform their own group identity and related practices - distinguished from those seen on eBay. This paper examines these distinctions in detail - the identifying traits or 'Shibboleths' of eBay amateurs - such as the incorrect spelling of 'Bakelite'.

Automatic Fire Detection: A Survey from Wireless Sensor Network Perspective

Automatic fire detection is important for early detection and promptly extinguishing fire. There are ample studies investigating the best sensor combinations and appropriate techniques for early fire detection. In the previous studies fire detection has either been considered as an application of a certain field (e.g., event detection for wireless sensor networks) or the main concern for which techniques have been specifically designed (e.g., fire detection using remote sensing techniques). These different approaches stem from different backgrounds of researchers dealing with fire, such as computer science, geography and earth observation, and fire safety. In this report we survey previous studies from three perspectives: (1) fire detection techniques for residential areas, (2) fire detection techniques for forests, and (3) contributions of sensor networks to early fire detection

An ethnography of a neighbourhood café: informality, table arrangements and background noise

Café society is something that many of us as customers and/or social theorists take for granted. Cafés are places where we are not simply served hot beverages but are also in some way partaking of a specific form of public life. It is this latter aspect that has attracted the attention of social theorists, especially Jürgen Habermas, and leads them to locate the café as a key place in the development of modernity. Our approach to cafés is to ‘turn the tables’ on theories of the public sphere and return to just what the life of a particular café consists of, and in so doing re-specify a selection of topics related to public spaces. The particular topics we deal with in a ‘worldly manner’ are the socio-material organisation of space, informality and rule following. In as much as we are able we have drawn on an ethnomethodological way of doing and analysing our ethnographic studies

Current achievements and future directions of physical weed control in Europe

This paper reviews major results achieved with physical weed control methods and strategies especially adapted for horticultural and agricultural crops. Mechanical methods, such as weed harrowing and inter-row hoeing, have provided promising results in cereals, pulse and oil seed rape, particularly when they are part of a strategy that also involves cultural methods such as fertiliser placement or crop seed vigour. In row crops, intra-row weeds constitute a major challenge, and research has mainly aimed at replacing laborious hand weeding with mechanization. A number of investigations have focussed on optimising the use of thermal and mechanical methods against intra-row weeds. And new methods are now under investigation such as robotic weeding for row crops with abundant spacing between individual plants and band-steaming for row crops developing dense crop stands

Impacts of directed tutorial activities in computer conferencing: a case study

This paper describes a qualitative study of asynchronous electronic conferencing by three tutorial groups on the same postgraduate course (Teaching English to Speakers of Other Languages Worldwide), forming part of an MA in Applied Linguistics (via Distance Education) at the Open University, UK. The groups varied in the degree to which the tutor participated in the discussion and in whether the tutor's input took the form of responding to student posts or the setting of tasks to scaffold the learners' development of academic skills. It is argued that the least interventionist strategy in terms of tutor response and task-setting resulted in the least productive conference discussion in terms of both communicative interaction and academic development, while a more interventionist role by the tutor depended for its success on characteristics of the tutor input and the task set

Addressivity and Sociability in “Celtic Men”

This paper is part of a larger project which examines the sociable dimensions of computer-mediated communication in local newsgroups on the Internet. This paper, however, takes as its primary data a complete thread of eighty five messages posted to RumCom’s largest ISP specific newsgroup,\ud rumcom.local. The messages share the subject header “Celtic Men” and play off contributors ideas about regional aspects of masculinity and male sexuality. As a whole they provide a good example of both a specific culturally located example of developing communication and a more general example of newsgroup CMC. Using this case as our exemplar we shall hold up for examination three matters: how the technology and software supplied by RumCom influence the form of interaction within the newsgroup; how different types of addressivity are used by posters to manage their communication; and how the notion of sociability figures as a useful device to characterise the specific traits of newsgroup interaction

New literacies and future educational culture

The paper draws attention to three developments that are crucial to online education. First, the new literacy required by group discussion in writing, i.e. by computer‐mediated communication ('e‐talk') is discussed Educators are urged to delimit and structure their courses so that online conversations in writing are successfully framed for effective discourse. Second, new literacy arising from the merging of multimedia with text is considered It is maintained that this will enhance communication, not debase it. Third, the way that increasing ease of information retrieval is eroding boundaries between traditional disciplines is discussed It is argued that this may create new difficulties in education. The paper recommends various ways of overcoming the problems that arise from the three developments

Cyberpsychology and Human Factors

The online environment has become a significant focus of the everyday behaviour and activities of individuals and organisations in contemporary society. The increasing mediation of communication has led to concerns about the potential risks and associated negative experiences which can occur to users, particularly children and young people. This is related to the emergence of the online environment as a location for criminal and abusive behaviour (e.g., harassment, sexual exploitation, fraud, hacking, malware). One of the key aspects of understanding online victimisation and engagement in criminal behaviours is the characteristics of online communication that are related to the affordances of the technologies, services and applications which constitute digital environments. The aim of this paper is to examine the influence of these characteristics on individual and group behaviour, as well as the associated opportunities for victimisation and criminal behaviour. These issues are of relevance for those involved in the design and implementation of technologies and services, as the ability to assess their potential use in this way can enhance strategies for improving the security of systems and users. It can also inform educational strategies for increasing user understanding of potential informational, privacy and personal risks, and associated steps to improve their security and privacy. Each of the main characteristics of mediated communication is examined, as well as their potential impact on individual and group behaviour, and associated opportunities for victimisation and offending. The article ends by considering the importance of recognising these issues when designing and implementing new technologies, services and applications
