Series in vector spherical harmonics : an efficient tool for solution of nonlinear problems in spherical plasmas

The series expansion of the plasma fields and currents in vector spherical harmonics has been demonstrated to be an efficient technique for solution of nonlinear problems in spherically bounded plasmas. Using this technique, it is possible to describe the nonlinear plasma response to the rotating high-frequency magnetic field applied to the magnetically confined plasma sphere. The effect of the external magnetic field on the current drive and field configuration is studied. The results obtained are important for continuous current drive experiments in compact toruses. © 2000 American Institute of Physics.

Understanding the value of social media in organisations : a taxonomic approach

While organizations strive to leverage the vast information generated daily from social media platforms and both decision makers and consultants are keen to identify and exploit this information’s value, there has been little research into social media in the business context. Social media are diverse, varying in scope and functionality, this diversity entailing a complex of attributes and characteristics, resulting in confusion for both researchers and organizations. Taxonomies are important precursors in emerging fields and are foundational for rigorous theory building. Though aspects of social media have been studied from various discipline perspectives, this work has been largely descriptive. Thus, while the need for a rigorous taxonomy of social media is strong, previous efforts to classify social media suffer limitations – e.g. lack of a systematic taxonomic method, overreliance on intuition, disregard for the users’ perspective, and inadequate consideration of purpose. Thus, this study was mainly initiated by the overarching question “How can social media in the business context be usefully classified?” In order to address this gap, the current paper proposes a systematic method for developing a taxonomy appropriate to study social media in organizations context, combining Nickerson et al,’s (2012) IS taxonomy building guidelines and a Repertory grid (RepGrid) approach.

Using enterprise information architecture methods to model wicked problems in information systems design research

Design Science is the process of solving ‘wicked problems’ through designing, developing, instantiating, and evaluating novel solutions (Hevner, March, Park and Ram, 2004). Wicked problems are described as agent finitude in combination with problem complexity and normative constraint (Farrell and Hooker, 2013). In Information Systems Design Science, determining that problems are ‘wicked’ differentiates Design Science research from Solutions Engineering (Winter, 2008) and is a necessary part of proving the relevance to Information Systems Design Science research (Hevner, 2007; Iivari, 2007). Problem complexity is characterised as many problem components with nested, dependent and co-dependent relationships interacting through multiple feedback and feed-forward loops. Farrell and Hooker (2013) specifically state for wicked problems “it will often be impossible to disentangle the consequences of specific actions from those of other co-occurring interactions”. This paper discusses the application of an Enterprise Information Architecture modelling technique to disentangle the wicked problem complexity for one case. It proposes that such a modelling technique can be applied to other wicked problems and can lay the foundations for proving relevancy to DSR, provide solution pathways for artefact development, and aid to substantiate those elements required to produce Design Theory.

Social licence to operate and the coal seam gas industry : lessons from social issues in established mining operations?

The recent growth of the coal seam gas industry has increased pressure on regional communities. Debate surrounding the industry is intense and a social licence to operate has yet to be granted to the industry in its entirety. This article presents an analysis of social issues surrounding the coal seam gas industry, making comparisons between two case studies: the Ranger and Jabiluka mines and the Yandicoogina mine. It presents the results of a desktop study, focussed on three topics: community identity; procedural justice and distributive justice, which provides a means for comparison and draws attention to central concerns. It is found that: power imbalances; changing community identities; potentially inequitable distributions of long term benefits and the process to distribute those benefits and negative perceptions of the industry as a whole serve to undermine the provision of a social licence to operate by communities and has the potential to impose significant negative impacts on companies within the industry.

Wicked problems in designing open online learning

This paper will report on the “wicked” problems encountered when designing an online course with bounded content in an unbounded learning environment. It will describe the dilemmas faced and decisions made by academics in an Australian university challenged by an institutional initiative to design radical, disruptive learning experiences making use of readily available online media. This bounded/unbounded environment demands new roles for instructors in adopting innovative pedagogies and teaching and learning strategies. It also creates changing and challenging roles for course designers as they deal with ill-defined parameters and unknown audiences. In this paper, we propose a novel methodology for making curricular decisions in ill-defined spaces.

Social justice in early years education : practices and understandings

The current political context necessitates discussions of social justice within education, and here we bring together early childhood professionals from a variety of perspectives to become part of the important debates that must be had. This special issue of Contemporary Issues in Early Childhood was first conceived at a meeting of academics interested in social justice in early childhood education in Albury, NSW, Australia. All of the editors are members of the Social Justice strand of the ARC Funded Excellence in Research in Early Years Education Collaborative Research Network (CRN), which is led by Charles Sturt University in partnership with Queensland University of Technology and Monash University. Some of the authors in this issue are also members of this research network, but their work is presented here with that of others from a variety of contexts. We believe that the combination of perspectives taken challenges old thinking about social justice in early years education in innovative ways.

A generalised deficit can account for problems in facial emotion recognition in schizophrenia

Neuroimaging research has shown localised brain activation to different facial expressions. This, along with the finding that schizophrenia patients perform poorly in their recognition of negative emotions, has raised the suggestion that patients display an emotion specific impairment. We propose that this asymmetry in performance reflects task difficulty gradations, rather than aberrant processing in neural pathways subserving recognition of specific emotions. A neural network model is presented, which classifies facial expressions on the basis of measurements derived from human faces. After training, the network showed an accuracy pattern closely resembling that of healthy subjects. Lesioning of the network led to an overall decrease in the network’s discriminant capacity, with the greatest accuracy decrease to fear, disgust and anger stimuli. This implies that the differential pattern of impairment in schizophrenia patients can be explained without having to postulate impairment of specific processing modules for negative emotion recognition.

Composing an email : social interaction in a preschool classroom

The chapter contributes understandings of digitally mediated interactions in early childhood classrooms. Ethnomethodological and conversation analysis approaches are used to analyse a video-recorded episode of children and teacher composing an email in a preschool classroom. In their talk we find how the teacher directs the children to what counts procedurally, such as the components of an email, and the teacher’s moral work in producing a culturally correct way form of personal communication. Such considerations of situated examples can encourage investigations of digital practices that extend beyond operational skills to broader understandings of digital practices as cultural and situated activities.

Investigating the link between carbon dioxide emissions and transport-related social exclusion in rural Northern Ireland

Carbon dioxide (CO2) is considered the most harmful of the greenhouse gases. Despite policy efforts, transport is the only sector experiencing an increase in the level of CO2 emissions and thereby possesses a major threat to sustainable development. In contrast, a reduced level of mobility has been associated with an increasing risk of being socially excluded. However, despite being the two key elements in transport policy, little effort has so far been made to investigate the links between CO2 emissions and social exclusion. This research contributes to this gap by analysing data from 157 weekly activity-travel diaries collected in rural Northern Ireland. CO2 emission levels were calculated using average speed models for different modes of transport. Regression analyses were then conducted to identify the socio-spatial patterns associated with these CO2 emissions, mode choice behaviour, and patterns of participation in activities. This research found that despite emitting a higher level of carbon dioxide, groups in rural areas possess the risk of being socially excluded due to their higher levels of mobility.

Citizens and social media in times of natural disaster: Exploring information experience

Introduction. Social media is becoming a vital source of information in disaster or emergency situations. While a growing number of studies have explored the use of social media in natural disasters by emergency staff, military personnel, medial and other professionals, very few studies have investigated the use of social media by members of the public. The purpose of this paper is to explore citizens’ information experiences in social media during times of natural disaster. Method. A qualitative research approach was applied. Data was collected via in-depth interviews. Twenty-five people who used social media during a natural disaster in Australia participated in the study. Analysis. Audio recordings of interviews and interview transcripts provided the empirical material for data analysis. Data was analysed using structural and focussed coding methods. Results. Eight key themes depicting various aspects of participants’ information experience during a natural disaster were uncovered by the study: connected; wellbeing; coping; help; brokerage; journalism; supplementary and characteristics. Conclusion. This study contributes insights into social media’s potential for developing community disaster resilience and promotes discussion about the value of civic participation in social media when such circumstances occur. These findings also contribute to our understanding of information experiences as a new informational research object.

Critical literacy finds a 'place': Writing and social action in a low-income Australian grad 2/3 classroom

In a study of socioeconomically disadvantaged children's acquisition of school literacies, a university research team investigated how a group of teachers negotiated critical literacies and explored notions of social power with elementary children in a suburban school located in an area of high poverty. Here we focus on a grade 2/3 classroom where the teacher and children became involved in a local urban renewal project and on how in the process the children wrote about place and power. Using the students' concerns about their neighborhood, the teacher engaged her class in a critical literacy project that not only involved a complex set of literate practices but also taught the children about power and the possibilities for local civic action. In particular, we discuss examples of children's drawing and writing about their neighborhoods and their lives. We explore how children's writing and drawing might be key elements in developing "critical literacies" in elementary school settings. We consider how such classroom writing can be a mediator of emotions, intellectual and academic learning, social practice, and political activism.

Changing the game: The role of social media in overcoming old media's attention deficit toward women's sport

Social media is now an integral part of modern sports broadcasting, which combines old and new media into a redefined and multidimensional experience for fans. The popularity of social media has particular implications for professional women's sports due to this convergence, and may be utilised by organisations to address some of the issues women's sports face from a lack of traditional broadcast coverage. This article discusses Twitter activity surrounding the ANZ Championship netball competition and analyses the ways social media can help transcend the structural challenges that “old” media has placed on professional women's sports.

Religion, spirituality, and mental health and social behaviour in young adulthood: A longitudinal study

Background The concept spirituality appears to be gaining increasing attention for its potential relationship to mental health, despite there being an absence of consensus on what spirituality is or whether it can be distinguished from religion (or religiousness) in operational terms. Spirituality is a term that is embraced within secular and non-secular contexts alike. As a consequence, spirituality as a concept encompasses forms of religiosity that are embedded in traditional religion and those that have little or no connection to traditional religious teachings. The emergence of religious/spiritual beliefs that depart from traditional religious thought represents one key feature of widespread religious change in contemporary societies. Non-traditional religious/spiritual beliefs need to be viewed within this context and thus be differentiated from traditional religious/spiritual beliefs when investigating connections between religion, spirituality, and mental health. Aims The current study seeks to compare the mental health of those whose beliefs are rooted in religious tradition with those whose beliefs deviate from traditional religious thought. The two main objectives of this study are: (1) to determine the extent to which religious background predicts endorsement of traditional and non-traditional religious/spiritual beliefs and church attendance in young adulthood, and; (2) to determine whether differential relationships exist between current religiosity, religious background, and mental health in young adulthood, and whether any observed differences are attributable to other characteristics of respondents like sociodemographic factors and health-risk behaviours. Methods Data were derived from the Mater-University of Queensland Study of Pregnancy, a longitudinal, prospective study of maternal and child health from the prenatal period to 21 years post-delivery. Religiosity was assessed among the study children in young adulthood from three items measured at the time of the 21-year follow-up. Religious background was assessed from information provided by the study mothers in earlier phases of the study. Young adult responses to items included in the Young Adult Self Report (Achenbach, 1997) were used to assess cases of anxiety/depression and externalising behaviour, and delusional ideation was assessed from their responses to the 21-item Peters et al. Delusions Inventory (PDI) (Peters & Garety, 1996). Results Belief in a spiritual or higher power other than God was found to be positively related to anxiety/depression, disturbed ideation, suspiciousness and paranormal ideation, high total PDI scores, as well as antisocial behaviour in young adulthood, regardless of gender. These associations persisted after adjustment for potential confounders. By contrast, young adults who maintain a traditional belief in God appear to be no different to those who reject this belief in regard to anxiety/depression. Belief in God was found to have no association with antisocial behaviour for males, but was observed to have a weak negative relationship with antisocial behaviour for females. This association failed to reach statistical significance however, after adjustment for other religious/spiritual and social characteristics. No associations were found between young adult belief in God and disturbed, suspicious or paranormal ideation, although a positive relationship was identified for high total PDI scores. Weekly church attendance was observed to reduce the likelihood of antisocial behaviour in young adulthood among males, but not females. Religious ideation was found to more prevalent among young adults who attend church on either a weekly or infrequent basis. No long-term effects on anxiety/depression or antisocial behaviour were evident from maternal belief in God, church attendance or religious affiliation in the young adults’ early lives. However, maternal church attendance predicted religious ideation in young adulthood. Offspring of mothers affiliated with a Pentecostal church in the prenatal period appear to have a high rate of religious ideation and high total PDI scores. Paranormal ideation in young adulthood appears to have no association with maternal religiosity in a young adult’s early life. Conclusion The findings from this study suggest that young adults who endorse non-traditional religious/spiritual beliefs are at greater risk for poorer mental health and aberrant social behaviour than those who reject these beliefs. These results suggest that a non-traditional religious/spiritual belief system involves more than mere rejection of traditional religious doctrine. This system of belief may be a marker for those who question the legitimacy of established societal norms and values, and whose thoughts, attitudes and actions reflect this position. This possibility has implications for mental health and wellbeing at both an individual and a societal level and warrants further research attention.
