On ""Schwinger mechanism for gluon pair production in the presence of arbitrary time dependent chromo-electric field""

Recently the paper ""Schwinger mechanism for gluon pair production in the presence of arbitrary time dependent chromo-electric field"" by G. C. Nayak was published [Eur. Phys. J. C 59: 715, 2009; arXiv:0708.2430]. Its aim is to obtain an exact expression for the probability of non-perturbative gluon pair production per unit time per unit volume and per unit transverse momentum in an arbitrary time-dependent chromo-electric background field. We believe that the obtained expression is open to question. We demonstrate its inconsistency on some well-known examples. We think that this is a consequence of using the socalled ""shift theorem""[arXiv:hep-th/0609192] in deriving the expression for the probability. We make some critical comments on the theorem and its applicability to the problem in question.

Gravitational field of a straight cosmic string in the framework of higher-derivative gravity

The gravitational properties of a straight cosmic string are studied in the linear approximation of higher-derivative gravity. These properties are shown to be very different from those found using linearized Einstein gravity: there exists a short range gravitational (anti-gravitational) force in the nonrelativistic limit; in addition, the derection angle of a light ray moving in a plane orthogonal to the string depends on the impact parameter.

Women of Substance : The Aspect of Education, Career and Female Identity in Pride and Prejudice and Bridget Jones's Diary

Although two hundred years separate Jane Austen and Helen Fielding and, subsequently, also their portrayals of society, the similarities outweigh the differences. When juxtaposing Pride and Prejudice and Bridget Jones’s Diary in the light of feminism it is evident that both books provide clear examples of the prevailing situation of women in each time and place. The aspects of the study, which are especially important today, show both the development and some degree of stagnation of women’s rights and identities.

The priority of temporal aspects in L2-Swedish prosody : Studies in perception and production

Foreign accent can be everything from hardly detectable to rendering the second language speech unintelligible. It is assumed that certain aspects of a specific target language contribute more to making the foreign accented speech intelligible and listener friendly, than others. The present thesis examines a teaching strategy for Swedish pronunciation in second language education. The teaching strategy “Basic prosody” or BP, gives priority to temporal aspects of Swedish prosody, which means the temporal phonological contrasts word stress and quantity, as well as the durational realizations of these contrasts. BP does not prescribe any specific tonal realizations. This standpoint is based on the great regional variety in realization and distribution of Swedish word accents. The teaching strategy consists virtually of three directives: · Stress the proper word in the sentence. · Stress proper syllables in stressed words and make them longer. · Lengthen the proper segment – vowel or subsequent consonant – in the stressed syllable. These directives reflect the view that all phonological length is stress-induced, and that vowel length and consonant length are equally important as learning goals. BP is examined in the light of existing findings in the field of second language pronunciation and with respect to the phonetic correlates of Swedish stress and quantity. Five studies examine the relation between segment durations and the categorization made by native Swedish listeners. The results indicate that the postvocalic consonant duration contributes to quantity categorization as well as giving the proper duration to stressed syllables. Furthermore, native Swedish speakers are shown to apply the complementary /V: C/ - /VC:/ pattern also when speaking English and German, by lengthening postvocalic consonants. The correctness of the priority is not directly addressed but important aspects of BP are supported by earlier findings as well as the results from the present studies.

Role of Culture in the Acquisition of CSL – From the Perspective of Intercultural Communication Competence

In the past few decades, the demands for coping with the rapid development of information communication technology, internationalization and globalization worldwide have shifted the focus of Chinese as a second language (CSL) towards intercultural communication competence in which the role of culture in the acquisition of CSL and in the pragmatic use of the language is emphasized and promoted. However, most of the present research in this academic area still remains only on a theoretical level.   In order to explore the possibilities and limitations of integrating Chinese culture and implementing intercultural communication theory into CSL education, an action research has been conducted since the beginning of 2013 to review an actual course for beginners. This paper will present the findings of the research: 1) By applying the theoretical framework of intercultural communicative competence, the findings indicated that the existing CSL course provided limited information explaining the cultural elements that are reflected in the Chinese language. 2) The findings also suggested that the cultural skills acquired in the students’ first language do influence their acquisition of CSL. This is demonstrated in the students’ written tasks such as introducing themselves and presenting other people, etc. The findings can be examples and resources for further research in this academic field.     

Risky business: stories from the field of rural community nurses' work in domestic violence.

This paper reports on a descriptive study into family violence in rural Victoria. Focus groups were held in a number of areas across rural Victoria with a total of 24 community nurse participants. The focus groups were audio-taped and the tapes transcribed to enable the clustering of themes. The dominant themes were: picking up cues, helping and helplessness, holding secrets and quiet resistance. Underpinning all these themes however, was the notion of 'risky business'. All nurses in the study gave examples of situations that they encountered; their ways of helping; of working sensitively; of working around a system that is unhelpful; and the ways in which their work while skilled, thoughtful and wise, is also costly in terms of the emotional wounds they carry. Rural nurses work with considerable risk and courage as they engage in the care and support of women experiencing family violence.

Specialist training in investigative and evidential interviewing: is it having any effect on the behaviour of professionals in the field?

While numerous concerns have been voiced over the past decade regarding the inappropriate question styles of investigative and evidential interviewers, there has been relatively little research, discussion, and critique in relation to the content, structure, and efficacy of existing interviewer training courses. This article provides a brief up-to-date summary of the essential elements of an investigative or evidential interview, followed by a review of research relating to the effectiveness of training programs for forensic interviewers and the factors that are needed to promote the use of appropriate questioning techniques. Finally, this article offers recommendations for future research and for the revision of existing training programs in forensic interviewing.

Back from the brink: reclaiming `quality` in the pursuit of a transformative education agenda

Discussions about ‘quality’ and ‘quality assurance’ abound in contemporary Australian universities. Since 1992, the Australian federal government has ‘promoted’ and/or mandated the use of particular quality assurance mechanisms within higher education and in 2001 The Australian University Quality Agency began to conduct the first of a series of ‘audits’ aimed at determining how well particular institutions meet standards and achieve
outcomes overseen, at least indirectly, by government agencies.

Home, school, community and their role in the provision of music education

The Department of Education, Science and Training (DEST), is supporting under the Australian Government Quality Outcomes Programme, a National Review of School Music Education. The review, which is intended to submit its report in mid 2005, is interested in investigating the current quality of teaching and learning of music in both primary and secondary schools. It aims to provide examples of best practice of teaching and learning of music, along with a set of recommendations for the development of future approaches and directions to improve the quality of music education offerings in Australian schools. This paper puts forward some proposals for consideration that will be forwarded to the Review and aims to generate debate about future approaches to the delivery of music education in Australian primary schools.
It argues that the home, school and community all have an important part to play in the music education of children, but that at present these three entities are insufficiently connected on a number of fronts, not least being an understanding about the purpose of young people’s engagement with music. There is no doubt that interest in the arts amongst Australians generally is high. A recent Australia Council report revealed that 85 per cent of its respondents agreed the arts are and should be an important part of the education of every young Australian and that what was needed was better arts education and opportunities for all young people. However, the opportunities need not be confined to those offered by the school sector. Engagement with out-of-school music includes both music encountered in the home, which may be affected by family influence, and music provided by the diversity of community organizations, which serve a real and complimentary role to classroom learning and achieve learning outcomes that schools often do not have the resources to foster. A number of proposals for action are suggested for consideration by those involved in education as a means of progressing the discussion. It asserts that there is much valuable activity occurring within the three locales of school, home and community, but a firmer relationship could be forged across all three to ensure young people’s on-going, life-long enjoyable engagement with music.

The application of non-profit marketing in the international higher education sector

This study considers the impact of the university service and learning environments (which we define as non educational factors) on student satisfaction among international postgraduate students from Asia studying in Australian universities. It is based on the expectations/perceptions paradigm and analyses the relationship between key variables and overall satisfaction of student groups in respect of their service and learning environments. The aim of this paper is to consider the importance of non-educational factors in international postgraduate university students, in particular, with regard to information and communication, infrastructure, and university recognition. The data used in this study is derived from a mail survey conducted among international postgraduate students from China, India, Indonesia and Thailand studying in five universities in Victoria. Structural Equation Modelling was used to understand the relationship between the constructs in this study. The results indicate that noneducation related factors are very important to international postgraduate students and they are predictors of overall satisfaction.

Flexible delivery in the Australian vocational education and training sector: Barrier to success identified in cases studies of four adult learners

Government policy in Australia is increasingly encouraging training organisations in the Vocational Education and Training (VET) sector to adopt flexible delivery approaches, but some researchers are sounding a note of caution. Evidence is emerging that Australian VET learners are not universally ready for flexible delivery, and this is reflected in high attrition rates and low pass rates. The literature on flexible delivery identifies a number of specific factors that can impact on the success of adult learners. However, there seems to be agreement that failure or dropout is not determined by a single factor, but by the interaction of a number of factors that build up over time. To understand these factors, we need to understand the learners - what their participation in education means to them, the context in which they are studying, and the numerous inter-connected factors that contribute to their failure to achieve a successful outcome. This paper discusses four case studies from a research project that followed up a small number of adult learners who enrolled in flexible delivery VET courses but did not achieve a successful outcome.

Think global, act local: from naive comparison to critical participation in the teaching of strategic international human resource management

In this paper, we examine the implications of ethnocentrism and paternalism in teaching approaches for the field of strategic international human resource management (SIHRM), as an example of management studies. We argue that the teaching of SIHRM has been approached in a colonizing fashion, joining and extending the territories of human resource management and organizational strategy through the definition and teaching of a new language and conceptual vocabulary. We explore philosophical approaches and processes involved in teaching SIHRM, and consider implications of pedagogical developments in this field of management education.
