Reducing yarn hairiness with a modified yarn path in worsted ring spinning

The spinning geometry of a ring frame plays an important role, and the twist triangle is the critical region in ring spinning. Changes in the spinning geometry may affect yarn properties. This paper examines the idea of ring spinning with a "diagonal" yarn path, and the effect of such a path on yam properties, particularly hairiness. Both "left diagonal" and "right diagonal" yam arrangements are tried on a 24-spindle Cognetex FLC worsted ring frame. The hairiness results obtained from the Zweigle hairiness meter show that the right diagonal yam path produces yams of lower hairiness than the conventional ring spun yarn in almost all the hair length groups. Yam evenness and tenacity are not as sensitive to the change in yarn path. The mean spindle speed at break is also tested, and there is some deterioration in spinning efficiency with the right diagonal yarn path, particularly at higher spinning speeds. Results from this study may help explain variations in yarns spun on poorly aligned ring frames.

Vested interest in the decision to resolve social dilemma conflicts

This exploratory study investigated the degree of correspondence between individual and group interests in the decision to adopt a sanctioning system to manage a shared resource with social dilemma properties. Fifty-two groups of four people accessed a "free-running" computer-simulated shared resource and had either equal or unequal resource access and experienced either an equitable or inequitable sanctioning system. Consistent with past research, a worse group outcome and greater voting for system change was found under the equitable than under the inequitable sanctioning system. However, at the individual level of analysis, the results suggested that the sanctioning systems did not have the same implications for all group members and that some of those differences predicted voting for system change. The study suggests the need to investigate the various decision frames and inequitable implications associated with structural/institutional change and calls for further investigation of dependencies between micro- and macro-level units of analysis.

A review of employment relations theories and their application

New developments in the industrial relations and human resource management have moved management and employee bargaining down to the level of the firm. In doing so they have generated a growing level of interest in the conduct of employment relations, not just at the level of specialist managers, who have traditionally had the responsibility for dealing with issues in this area, but across management as a whole. There is thus a growing need for managers to place more emphasis on achieving a greater symmetry between commercial objectives and employment practices. This paper looks at the predicates of managerial authority and its legitimacy, and how personal assumptions and value systems (i.e., ‘frames of reference’) held by managers can predispose them to view the nature of work and workplace relations in particular ways. The paper also presents
and aligns a range of contemporary theories within the province of such systems, with the aim being to show how judgements made about the worth or otherwise of a given range of theories are inevitably shaped by the type of value system and set of assumptions one holds towards the
world of work. The paper concludes by offering a practical guide to managers on how to evaluate their own assumptions and value systems when applying the noted theories and concepts to real world circumstances. In doing so, the paper provides a tool kit of theories and concepts that should allow managers to avoid engaging in workforce management practices that are either illconceived or based on intuitive premises.

Misuse of the term 'stakeholder' in public relations

This article queries the relatively recent adoption of the term 'stakeholder', borrowed from the UK political and the US business management spheres, in public relations academic writing. The article concludes that these spheres use the term in a normative or ideological manner that has worrying implications. The term frames people as having a pre-existing relationship with the governments or business organisations which name them as such. This process of incorporation prejudges and potentially obscures the real relations of groups of people vis-à-vis governments and business organisations which they may wish to have nothing to do with. An argument is mounted for the defence of the term 'publics'. It is pointed out that a key originator of stakeholder theory opposes the notion of 'publics' as closer to a notion of an uncontrolled audience. The article argues that the notion of 'publics' is more fitting than the notion of 'stakeholders' if public relations is about acknowledging this uncontrollability, and to do with advising organisations about their positioning in the democratic milieu. On the other hand, the notion 'stakeholders' may be the right one if public relations is simply aimed at immediately shaping people's behaviour, irrespective of longer term and wider political implications.

Dwelling in the landscape: from Blairgowrie House to Portsea Palace

Ackerman begins his book "The Villa" (1995) with these words: 'A villa is a building in the country designed for its owner's enjoyment and relaxation .... [it] accommodates a fantasy which is impervious to reality.' He concludes: , ... the country, in exacting confrontations with the immanent brute forces and sensuous enchantments of nature, prompts inspired responses.' Blairgowrie House - the villa in the landscape - was built in the 1870s and the 'Portsea Palace' - a personal club med resort - in the late 1990s. The notion of an inspired response and the concept of dwelling poetically are manifestly absent in the Portsea Palace. Why?

This paper explores architecture and landscape - particularly 'domestic' architecture and coastal landscapes in Victoria's Nepean Peninsula. It looks closely at what architects mean when they say their design reflects place, relates to site, is climate specific, is close to nature, responds to the landscape, and/or is sensitive to the environment. Exemplars from different centuries are examined in their philosophical contexts and frames of reference. The complexities of the notion of place and identity, belonging, and dwelling (in the Heideggerian sense) are examined to identify the shift that has occurred over time as science and technology have ostensibly freed 'modern man' from 'a direct dependence on places' (Norberg Schultz). The alienation and loss that has eventuated - for humans and for the environment - will be critically analysed and assessed.

Triage nurses' clinical decision making : an observational study of urgency assessment

Background. Researchers have described both the various decision tasks performed by triage nurses using self-report methods and identified time as a factor influencing the quality of triage decisions. However, little is known about the decision tasks performed by triage nurses when making acuity assessments, or the factors influencing triage duration in the real world.

Aims. The aims of this study were to: describe the data triage nurses collect from patients in order to allocate a triage priority using the Australasian Triage Scale (ATS); describe the duration of nurses' decision making for ATS categories 2–5; and to explore the impact of patient and nurse variables on the duration of the triage nurses' decision making in the clinical setting.

Design. A structured observational study was employed to address the research aims. Observational data was collected in one adult emergency department located in metropolitan Melbourne, Australia. A total of 26 triage nurses consented and were observed performing 404 occasions of triage. Data was collected by a single observer using a 20-item instrument that recorded the performance frequencies of a range of decision tasks and a number of observable patient, nurse and environmental variables. Additionally, the nurse–patient interaction was recorded as time in minutes.

Results. It was found that there was limited use of objective physiological data collected by the nurses' in order to decide patient acuity, and large variability in the duration of triage decisions observed. In addition, analysis of variance indicated strong evidence of a true difference between triage duration and a range of nurse, patient and environmental variables.

Conclusion. These findings have implications for the development of practice standards and triage education. In particular, it is argued that practice standards should include routine measurement of physiological parameters in all but the collapsed or obviously unwell patient, where further delay may impede the delivery oftime-critical intervention. Furthermore, the inclusion of arbitrary time frames for triage assessment in practice standards are not an appropriate method of evaluating triage decision making in the real world.

Roman concept of mental capacity to make end-of-life decisions

When assessing decisional competence of patients, psychiatrists have to balance the patients' right to personal autonomy, their condition and wishes against principles of medical ethics and professional discretion. This article explores the age-old legal and ethical dilemmas posed by refusal of vital medical treatment by patients and their mental capacity to make end-of-life decisions against the background of philosophical, legal and medical approaches to these issues in the time of the Younger Pliny (c62–c113 CE). Classical Roman discourse regarding mental competency and "voluntary death" formed an important theme of the vast corpus of Greco-Roman writings, which was moulded not only by legal permissibility of suicide but also by philosophical (in modern terms, moral or ethical) considerations. Indeed, the legal and ethical issues of evaluating the acceptability of end of life decisions discussed in the Letters are as pertinent today as they were 2000 years ago. We may gain valuable insights about our own methodologies and frames of reference in this area of the law and psychiatry by examining Classical Roman approaches to evaluating acceptability of death-choices as described in Pliny's Letters and the writings of some of his peers.

Returning to work: exploring the experiences of women with acute coronary syndromes

Aims: The aim of this study was to explore the transition experiences of Australian women in resuming paid employment after an acute coronary syndrome (ACS) event. Background: Until recently cardiovascular research has focused predominantly on men but this is changing and research exploring women’s experiences of ACS has increased. Despite knowing that many women do not resume paid employment following an ACS event, little is known about the experience of those women who do, even though it is understood that returning to the previous level of employment after an ACS event is a positive outcome. Design: An exploratory qualitative approach underpinned by naturalistic inquiry was undertaken. Methods: A purposive sample of seven women who had experienced their first ACS event 12 months ago was selected. Each woman was interviewed using a semi–structured format and their interviews were transcribed verbatim. Thematic analysis of the transcript set and conceptual mapping were employed to formulate key themes. Findings: All women (mean age 52.6 years) resumed paid employment at various stages during their recovery, but reported similar transition processes. Three key themes representing this process were identified: primary motivation; influence through guidance and support; and resuming paid employment. Conclusions: Study findings revealed that these women required substantial support from family, friends and employers, with ongoing guidance from health professionals to return to paid work. The time frames for their return varied and some modified their roles within the workforce to enable them to return to paid work. However, formal cardiac rehabilitation did not appear to have a significant impact on these participants' decisions to return to work. They felt that more information about this decision may have been helpful if given at the time of cardiac rehabilitation.

New models for learning flexibility: νegotiated choices for both academics and students

‘Flexible learning’ represents a need associated with ‘lifelong learning’ and the equipping of graduates to actively engage in a ‘knowledge society’. While the precise meaning of each of these terms is not easy to discern, notions of flexible learning have progressed an evolutionary path that concentrates on students as though they are the only stakeholder group in the higher education environment that would benefit from choice. Academic discourse also presumes that all cultural groups making up the increasingly diverse student population aspire to engage in student-centred learning as a precursor to involvement in a knowledge economy. In this environment academics have been encouraged to embrace online teaching and promote a more student-centred learning approach when the natural inclination and talent of many academics may make this style of pedagogy so challenging that learning outcomes are compromised. We question this ‘one size fits all’ mentality and suggest a model that empowers both the students and academics by allowing them the ability to choose the approach that suits their educational philosophy and preferred learning/teaching approach. The model represents an innovation in flexibility that recognises initial embedded learning foundation abilities and reaches both teachers and learners by utilising their own frames of reference.

Framing the discourses of harm and loss: a case study of power relations, mobile phones, and children in Australia

The current penetration of mobile phones in Australia is 92% and it records one of the world’s highest rates of ownership among children under 18. The paper reviews the literature on mobile phones and Australian children and examines the various discourses dominating the public debates; the systematic frames used in these discourses; and whose interests are served in the process. The frames discussed fall under the optimistic (gains); pessimistic (losses, costs or harms); pluralistic (technology per se is neutral but how it is used matters); historical development (skills learnt and the importance of using mobiles); futuristic predictions (promises and dangers for the future); current uses (connectivity, convergence and interactivity); and the techno-realist view (as a mixed blessing) views of technology. Taking the critical perspective and borrowing from Joshua Meyrowitz, the paper illustrates how mobile phones have eroded parental power over how, when, where and with whom their children communicate, surpassing adult supervision, intervention or knowledge, while at the same time, becoming a ‘digital leash’ for parents to re-establish their control an d an ‘umbilical cord’ for their off spring to remain connect! ed with parents, at all times.

Measuring message framing effects across Europe

This study examines consumer response to positively versus negatively framed advertising messages across seven Central and Western European countries. The frames elicited significantly different emotional, cognitive and attitudinal reactions. Groups of nations where consumers responded more homogeneously to the frames were different from the groups plotted according to cultural context. In addition, the results present a new perspective for international marketing. While advertising content and imagery has often been designed to account for known or assumed differences across nations, the findings of this study show that neglecting even subtle national differences can be misleading and can result in adverse consequences. The study has shown that consumers in similar countries, such as Poland, Czech Republic and Hungary, respond quite differently to positively or negatively framed advertisements. This suggests that even advertising campaigns that are designed for relatively narrow international audiences may not be effective when featuring an inappropriate message frame.

Editorial

In the way that submissions to journals sometimes observe a strange synchronicity, this issue commences with three essays focusing on film. Relatively little work has been carried out on the ideologies of films designed specifically for children or of that large body of films regarded as family viewing, and which cater both to child viewers and also to the adults who accompany them. The three ‘film’ essays we present here apply a variety of theoretical and methodological frames to films which in the main fit within the second of these categories—family films.

Mobile phones and children : an Australian perspective

Mobile phones in Australia record one of the world’s highest rates of ownership among children under 18. This paper examines issues of mobile phones and Australian children and the various discourses (systematic frames) used in discussing their effects. These are the optimistic (gains); pessimistic (losses, costs or harms); pluralistic (technology per se is neutral but how it is used matters); historical development (importance and skills learnt); futuristic predictions (promises and dangers); current uses (connectivity, convergence and interactivity); and techno-realist view (as a mixed blessing). Taking the Justification View of Technology that sees technological adoption as a gamble and borrowing from Joshua Meyrowitz, it examines how mobile phones have eroded parental power over how, when, where and with whom their children communicate, while at the same time, becoming a ‘digital leash’ for parents to re-establish their control and an ‘umbilical cord’ of children to remain connected with parents at all times.
