Recent studies on yarn tension and energy consumption in ring spinning

High energy consumption remains a key challenge for the widely used ring spinning system. Tackling this challenge requires a full understanding of the various factors that contribute to yarn tension and energy consumption during ring spinning. In this paper, we report our recent experimental and theoretical research on air drag, yarn tension and energy consumption in ring spinning. A specially constructed rig was used to simulate the ring spinning process; and yarn tension at the guide-eye was measured for different yarns under different conditions. The effect of yarn hairiness on the air drag acting on a rotating yarn package and on a ballooning yarn was examined. Models of the power requirements for overcoming the air drag, increasing the kinetic energy of the yarn package (bobbin and wound yarn) and overcoming the yarn wind-on tension were developed. The ratio of energy-consumption to yarn-production over a full yarn package was discussed. A program to simulate yarn winding in ring spinning was implemented, which can generate the balloon shape and predict yarn tension under a given spinning condition. The simulation results were verified with experimental results obtained from spinning cotton and wool yarns.

International sex offender registration laws : research and evaluation issues based on a review of current scientific literature

In many jurisdictions, anyone convicted of a sexual offense is required to register with police, often for life. Nine different countries have now implemented sex offender registries in an attempt to protect the public from the perceived threat posed by sexual offenders. Yet such laws have been criticized as being overly inclusive, tying up limited law enforcement resources to track many offenders who pose little risk of sexual reoffending. This paper considers the available research evidence relevant to the effectiveness of such laws for the deterrence of sexual offending and the investigation of sex crimes. It is concluded that significant gaps persist in our knowledge of whether existing laws effectively reduce sexual offending or reoffending and that large-scale, well-designed studies of the impact of sex offender registration on rates of offending, the collateral consequences to offenders and their families, and the costs of such laws are needed.

Advanced virtual engineering educational program for engineering research and teaching excellence

In this paper, an advanced virtual engineering educational program developed at University of South Australia for both on-campus and off-shore students will be studied. This extensive training program is based on a comprehensive online tutorial and comprises both face-to-face and online learning. The program provides a tailored evaluation format to ensure that all postgraduate students, including course work and research students, will have appropriate exposure to updated learning skills and research resources. Although the internet (WWW) is the primary resource being used in this educational program, other resources such as video conference, video taping, and face-to-face lecturing have also played a role in promoting engineering teaching and research excellence. The feedback from students in recent years has been very encouraging, showing increased information literacy skills and improved researching abilities. As off campus class numbers have increased, further development of the program to meet their requirement has been a priority.

An advanced virtual engineering educational program for engineering research and teaching excellence.

In this paper, an advanced virtual program in engineering education developed at the University of South Australia for both on-campus and offshore students is described. This extensive training program is based on a comprehensive online tutorial and comprises both face-to-face and online learning. The program provides a tailored evaluation format to ensure that all postgraduate students, including those doing coursework and research, will have appropriate exposure to updated learning skills and research resources. Although the internet is the primary resource used in this educational program, other resources, such as videoconferencing, video-taping and face-to-face lecturing, have also played a role in promoting engineering teaching and research excellence. The feedback from students in recent years has been very encouraging, and students have shown increased information literacy skills and improved researching abilities. As off-campus class numbers have increased, further development of the program to meet their requirements has been a priority.

Video streaming: Implementation and evaluation in an undergraduate nursing program

Video streaming technology enables video content, held on the web sites, to be streamed via the web. We report the implementation and evaluation of video streaming in an undergraduate nursing program in a metropolitan university in Australia. Students (n = 703) were emailed a survey with a 15% response rate. We found that 91% (n = 74) of respondents stated that video streaming assisted their learning. Forty-six percent(n = 50) of students had difficulty accessing video streaming (particularly at the beginning of the study period). Over a 97-day period there were 8440 “hits” to the site from 1039 different internet protocol (IP) addresses. There were 4475 video streaming sessions undertaken by users. Video streaming was used for reviewing previously attended lectures (52%, n = 56), examination preparation (34%, n = 37), viewing missed lectures (27%, n = 29) and class preparation (9%, n = 10). Our experience with the introduction of video streaming has met with general enthusiasm from both students and teaching staff. Video streaming has particular relevance for rural students.

Cause and effect in studies on unemployment, mental health and suicide: a meta-analytic and conceptual review

Background There are ongoing questions about whether unemployment has causal effects on suicide as this relationship may be confounded by past experiences of mental illness. The present review quantified the effects of adjustment for mental health on the relationship between unemployment and suicide. Findings were used to develop and interpret likely causal models of unemployment, mental health and suicide. Method A random-effects meta-analysis was conducted on five population-based cohort studies where temporal relationships could be clearly ascertained. Results Results of the meta-analysis showed that unemployment was associated with a significantly higher relative risk (RR) of suicide before adjustment for prior mental health [RR 1.58, 95% confidence interval (CI) 1.33–1.83]. After controlling for mental health, the RR of suicide following unemployment was reduced by approximately 37% (RR 1.15, 95% CI 1.00–1.30). Greater exposure to unemployment was associated with higher RR of suicide, and the pooled RR was higher for males than for females. Conclusions Plausible interpretations of likely pathways between unemployment and suicide are complex and difficult to validate given the poor delineation of associations over time and analytic rationale for confounder adjustment evident in the revised literature. Future research would be strengthened by explicit articulation of temporal relationships and causal assumptions. This would be complemented by longitudinal study designs suitable to assess potential confounders, mediators and effect modifiers influencing the relationship between unemployment and suicide.

A review of studies on information systems and SMEs in high ranked IS journals (2000-2014)

This paper identifies novel approaches to future small and medium enterprise (SME) research from a review of articles, and then introduces the papers in this AJIS special section which evidence these approaches. More specifically, the paper makes an important contribution by reviewing 61 articles in high ranked IS journals (2000-2014) and introducing three new facets which are used to analyse research on SME adoption/use of IS (units of analysis, SME sizes and SME types) not considered in previous literature review studies. These facets provide thebasis for proposing various future research opportunities. The editorial then introduces the four papers in this special section covering the research theme on SMEs, and highlights the contributions they make using the three facets.

Communication of scientific uncertainty: International case studies on the development of folate and vitamin D Dietary Reference Values

Objective Transparent evidence-based decision making has been promoted worldwide to engender trust in science and policy making. Yet, little attention has been given to transparency implementation. The degree of transparency (focused on how uncertain evidence was handled) during the development of folate and vitamin D Dietary Reference Values was explored in three a priori defined areas: (i) value request; (ii) evidence evaluation; and (iii) final values. Design Qualitative case studies (semi-structured interviews and desk research). A common protocol was used for data collection, interview thematic analysis and reporting. Results were coordinated via cross-case synthesis. Setting Australia and New Zealand, Netherlands, Nordic countries, Poland, Spain and UK. Subjects Twenty-one interviews were conducted in six case studies. Results Transparency of process was not universally observed across countries or areas of the recommendation setting process. Transparency practices were most commonly seen surrounding the request to develop reference values (e.g. access to risk manager/assessor problem formulation discussions) and evidence evaluation (e.g. disclosure of risk assessor data sourcing/evaluation protocols). Fewer transparency practices were observed to assist with handling uncertainty in the evidence base during the development of quantitative reference values. Conclusions Implementation of transparency policies may be limited by a lack of dedicated resources and best practice procedures, particularly to assist with the latter stages of reference value development. Challenges remain regarding the best practice for transparently communicating the influence of uncertain evidence on the final reference values. Resolving this issue may assist the evolution of nutrition risk assessment and better inform the recommendation setting process.

Two studies on Twitter networks and tweet content in relation to Amyotrophic Lateral Sclerosis (ALS): conversation, information, and ‘Diary of a Daily Life’

To date, there is no research examining how adults with Amyotrophic Lateral Sclerosis (ALS) or Motor Neurone Disease (MND) and severe communication disability use Twitter, nor the use of Twitter in relation to ALS/MND beyond its use for fundraising and raising awareness. In this paper we (a) outline a rationale for the use of Twitter as a method of communication and information exchange for adults with ALS/MND, (b) detail multiple qualitative and quantitative methods used to analyse Twitter networks and tweet content in the our studies, and (c) present the results of two studies designed to provide insights on the use of Twitter by an adult with ALS/MND and by #ALS and #MND hashtag communities in Twitter. We will also discuss findings across the studies, implications for health service providers in Twitter, and directions for future Twitter research in relation to ALS/MND.

Design, format, validity and reliability of mutiple choice questions for use in nursing research and education

Multiple choice questions are used extensively in nursing research and education and play a fundamental role in the design of research studies or educational programs. Despite their widespread use, there is a lack of evidence-based guidelines relating to design and use of multiple choice questions. Little is written about their format, structure, validity and reliability of in the context of nursing research and/or education and most of the current literature in this area is based on opinion or consensus. Systematic multiple choice question design and use of valid and reliable multiple choice questions are vital if the results of research or educational testing are to be considered valid. Content and face validity schould be established by expert panel review and construct validity should be established using ‘key check’, item discrimination and item difficulty analyses. Reliability measures include internal consistency and equivalence. Internal consistency should be established by determination of internal consistency using reliability coefficients while equivalence should be established using alternate form correlation. This paper reviews literature related to the use of multiple choice questions, current design recommendations and processes to establish reliability and validity, and discusses implications for their use in nursing research and education.

Differences between differentiators and cost leaders in market research and internal CRM usage

The Porter strategy types of Differentiation and Cost Leadership are put forward as strategies leading to competitive advantage (Porter 1980). These types have quite contrasting implementation guidelines in terms of human resources, organisational structure, job design decision-making process, control systems, and information systems. These internal contrasts suggest Differentiators and Cost Leaders require contrasting roles for market research and internal CRM systems. Very few studies have explored the contingent role business strategy may have in explaining contrasting roles in marketing information systems or market research.

This study involved a cross-industry postal survey of 240 Australian marketing managers. One contribution of this study was to find market research having quite different roles in supporting Marketing (i.e. brand) Differentiators compared to Product (i.e. innovative feature) Differentiators. Surprisingly only one market research role differed when comparing Cost Leaders with Marketing Differentiator strategies. A final contribution was to find that no one strategy having a greater reliance on internal CRM systems in supporting decisionmaking.
