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.

The purpose of this chapter is to provide a framework to guide learning and teaching practice in next generation learning spaces. The framework is informed by both learning and teaching theory and the current context of the sector. The framework provides guidance to those who teach in next generation learning spaces and is illustrated with examples of effective pedagogic practices that use the affordances of spaces while avoiding their limitations. The chapter discusses the tension between next generation learning space design and use. Design is influenced by drivers ranging from a need to accommodate ever-larger student numbers and responding to digital technologies and other developments in educational media, to providing for new approaches to learning. Use is determined by understandings of the teaching task, which can range from presentation by a teacher through to students working individually or in groups to generate meaningful knowledge, useful skills and professional values. In this chapter we identify drivers underpinning the creation and design of next generation learning spaces in universities today and associated expectations of the ways in which the spaces will be used. We reflect on understandings of sound pedagogic practice and work through to implications for learning and teaching in NGLS. In some cases advocated pedagogic practice asks teaching staff to make the most of spaces designed to allow students to engage constructively in their learning. In other cases it involves teaching constructively in spite of the design of the space.

MANY and sundry are the worries which fall to the lot of the librarian, and the matter of book‐repair is not the least among them. The very limited book‐fund at the disposal of most public library authorities makes it imperative on the part of the librarian to keep the books in his charge in circulation as long as possible, and to do this at a comparatively small cost, in spite of poor paper, poor binding, careless repairing, and unqualified assistants. This presents a problem which to some extent can be solved by the establishment of a small bindery or repairing department, under the control of an assistant who understands the technique of bookbinding.

This issue is a selected bibliography covering the subject of leadership.

After decades of declining strike rates in the industrialized world, recent years have seen a surge of militant walkouts in the global South, political strikes in Europe, and unconventional strikes in nonunion sectors in the United States. This new diversity of strike action calls for a new theoretical framework. In this paper, we review the historical strengths and limits of traditions of strike theory in the United States. Building on the emerging power resources approach, we propose a model based on a multidimensional view of associational power, power resources, and arenas of conflict in the economy, state, and civil society. We demonstrate the utility of our approach via a case analysis of strikes in the “Fight for $15” campaign in the United States.

As our correspondent on another page suggests, the economic crisis may have reactions upon libraries. The most obvious one he mentions is the increased difficulty we shall experience in obtaining American books. Not all libraries, public or private, make any special collection of books published in the United States, although there has been an increasing tendency to buy more as the relations of the two countries have grown closer through their common struggle; in fact, we know libraries which have spent many hundreds of pounds in the course of the past year or two on the select lists of books which have been made for us by American librarians. It is most unfortunate that the manipulation of dollar currency should have brought about a situation in which even the exchange of ideas between the countries becomes more difficult. One suggestion might be made and that is that our American colleagues should continue to sift the literature of this time of famine for us, so that further select lists may be available in better days.

Learning gain – the attempt to measure the different ways in which students benefit from their learning experience – is now a core part of government plans for higher education across many countries. A focus on student outcomes is a key strand of enquiry for judging quality and assessing value for money. New approaches to quantifying learning gain and new metrics were developed through 13 pilot projects across England. Evaluation of the projects explored the theoretical underpinnings of the metrics including behavioural, cognitive and affective approaches, as well as progress and outcome measures, and identified challenges to measuring learning gain. In this chapter policy implications of the global accountability agenda are discussed, including the use of metrics to drive enhancement, rank excellence and ensure quality and standards.

The management of children′s literature is a search for value and suitability. Effective policies in library and educational work are based firmly on knowledge of materials, and on the bibliographical and critical frame within which the materials appear and might best be selected. Boundaries, like those between quality and popular books, and between children′s and adult materials, present important challenges for selection, and implicit in this process are professional acumen and judgement. Yet also there are attitudes and systems of values, which can powerfully influence selection on grounds of morality and good taste. To guard against undue subjectivity, the knowledge frame should acknowledge the relevance of social and experiential context for all reading materials, how readers think as well as how they read, and what explicit and implicit agendas the authors have. The good professional takes all these factors on board.

Since the first Volume of this Bibliography there has been an explosion of literature in all the main areas of business. The researcher and librarian have to be able to uncover specific articles devoted to certain topics. This Bibliography is designed to help. Volume III, in addition to the annotated list of articles as the two previous volumes, contains further features to help the reader. Each entry within has been indexed according to the Fifth Edition of the SCIMP/SCAMP Thesaurus and thus provides a full subject index to facilitate rapid information retrieval. Each article has its own unique number and this is used in both the subject and author index. The first Volume of the Bibliography covered seven journals published by MCB University Press. This Volume now indexes 25 journals, indicating the greater depth, coverage and expansion of the subject areas concerned.

While some libraries have done their best over the years to inform the public as to what they are doing and can do as regards helping readers, others seem to move along without making any special effort to publicise their facilities. In the old days modesty was a virtue, but now it is its own reward. Government departments, which used to shun the limelight, now employ public relations officers in large numbers, and professional bodies and big business houses constantly seek publicity. Times have changed, and the battle is to the strong; and it is unfortunately generally felt that the institution or service that does not speak for itself has little to speak about. It may frankly be said that if a service is in a position to enlarge its sphere of influence and esteem it should do so to the utmost of its endeavour. But it will be granted that if its publicity is not justified by performance, there will likely be an unhappy reaction.
