Abstract
In recent work on the preparation of small samples of dye dispersions, a simple method has been developed of quantifying particle sizes and stability in dispersion. A method sometimes used by laboratories is to spot a filter paper with a dilute dispersion and observing the lateral spread of the dye or pigment. Particles lacking adequate stabilisation will tend to be precipitated near the centre of the spot, the carrier medium spreading out to leave a translucent halo. It is considered that precipitation is caused by the electrostatic charges on the fibres of the filter paper. This method can, in many instances, offer a guide to the quality of the dispersion, but an objection is that the results embody variable causative factors, making the test subjective and unless great care is taken, the test may fail to answer the criterion of repeatability and reproducibility. The authors have found that a dispersion with particles of dye with a medium size of one micron show vigorous Brownian motion over several hours of storage time and yet the sample offers anomalous results with a spot test on filter paper.

Abstract
The assumption is often made in considering the blending or mixing of two or more phases that interparticle forces are not significant. Where one is considering components to be blended which are relatively coarse, emphasis is placed on densities and shape or geometry, but when any of the components are fine, say, below 300 BSS, surface forces on the particles of powder can exert a predominant effect. The problem of blending may become acute where a relatively coarse powder needs to be mixed with a very fine one and where there is a high ratio between the components.

Abstract
This chapter reviews the study of individual differences in information behaviour; those differences which are not due to demographic factors such as age, gender, education or occupation, but rather to personality factors and to learning and thinking styles. It examines studies of patterns in information behaviour and of personality and similar factors in groups of information-focused occupations, as well as studies which have explicitly sought to relate information behaviour to such factors. The aim of the chapter is to assess how far we have come in being able to identify and measure ‘information style’, a quality different from any other categorisation of personality or of intellectual styles. If this goal were achieved, it would be a valuable concept for the academic study of information-related behaviours, as well as being of practical usefulness for the design of information systems and services, the evaluation of the effectiveness of such systems and the training of users. It could also allow a tailored provision of information, particularly for creative or innovative purposes.

Abstract
In a communication which appeared in The Times, and which Mr. Max Pemberton has also addressed to this Journal, Mr. Pemberton observes that during the Great War a Commercial Treaty was made between this country and its oldest ally, Portugal. One of the considerations for this Treaty was that Great Britain reserved to Portugal the sole right of use of the name “Port” to be applied to wines certified as such by the Portuguese Government. Before that Treaty there was no legal restriction of the use of the word “port,” which could be, and was, applied to cheap Spanish and even British wines—such as “Tarragona Port” and “British Port.” Unfortunately, in granting Portugal the exclusive right to the word “Port,” our Government made no stipulation as to the standard below which the Portuguese wines should not be certified as port, and, in effect, the Treaty bound the English law to follow the Portuguese law in this matter. Port is a strong wine made from vines grown on the banks of the Upper Douro, and “fortified” at the vintage by the addition of fine grape brandy. Its strength is a vital and distinctive characteristic, and at the time when the Treaty was made, and for very many years before that, the strength standard recognised by all reputable shippers was not under 35 per cent. of proof spirit. At the time of the Treaty, our wine duty was 2s. 6d. per dozen for wines up to 30 per cent., and 6s. per dozen for wines above that strength. so that all “recognised” ports then paid our higher rate of duty.—In 1920 our wine duties were doubled and all wines over 30 became chargeable at 12s. per dozen, instead of 6s. With a view to reducing costs some syndicates in Portugal then started shipping ports to this country at strengths below 30 per cent., thus saving 7s. a dozen to the buyers. But this saving was not necessarily passed to the consumer, and as, unfortunately, the law does not require a statement of the strength of port on the label, these low‐strength wines can be sold to the public at the same prices as the recognised high‐grade and high‐strength ports. At present, therefore, the public has no security as to strength, unless it insists on buying ports of the well‐known brands of reputable, houses, which carry a guarantee that they are of full strength, and these low‐strength wines sold as port are pouring into this country in an ever‐increasing volume, nearly three times as much having been shipped to Great Britain in the year 1924–5 as in 1921–22. If all these 2,228.842 gallons of low‐duty port imported into this country paid the higher rate of wine duty, the Revenue would have received £390,000 more from them than it actually did—in other words, the difference in the duty paid on these wines has resulted in a loss of that sum to the British revenue. Our Government could not have foreseen, when the treaty was made, how it would be evaded. From the revenue point of view, therefore, as well as that of the consumer, there is a clear case for regulating the strength at which wines may be described as “port.”—Port now plays so great a part in the wine dietary of this country that there should be an amendment of our law which would compel a statement on all port labels as to the strength of the wine—whether above or below the 30 per cent. duty line—in protection of the British consumer, who, in the meantime, can protect himself only on insisting on a disclosure as to whether his wine be full strength or otherwise. Indeed, some of the leading houses have found it necessary already to state on their labels and in their advertisements that their ports are of “full strength” as a safeguard to the buyer. Undoubtedly, some legal protection is required for the growing army of port consumers, in accordance with the precedent by which the law compels disclosure of strength in the case of whisky and other spirits below 35 degrees under proof. The public would then be protected against a form of the “confidence trick” and vendors of port could not complain if they were required to state the strength‐standard of their wine. Strong wines (over 30 degrees) from our Colonies were granted in the last Budget a preference of 8s. per dozen in duty, with a deliberate view to the development of Empire trade. Such is the magic of the word “port,” however, that so long as the wines are subject to the competition of low‐duty Portuguese wines at a cheap price to which the name “port” may be applied (Colonial wines are not permitted by law to use that name) the preference wines cannot be fully effective. If our Imperial wines containing over 30 per cent. of proof spirit cannot be described as port, it seems unfair that the name should be allowed to Portuguese wines containing less than 30 per cent. of proof spirit.

Abstract
THE Reference Department of Paisley Central Library today occupies the room which was the original Public Library built in 1870 and opened to the public in April 1871. Since that date two extensions to the building have taken place. The first, in 1882, provided a separate room for both Reference and Lending libraries; the second, opened in 1938, provided a new Children's Department. Together with the original cost of the building, these extensions were entirely financed by Sir Peter Coats, James Coats of Auchendrane and Daniel Coats respectively. The people of Paisley indeed owe much to this one family, whose generosity was great. They not only provided the capital required but continued to donate many useful and often extremely valuable works of reference over the many years that followed. In 1975 Paisley Library was incorporated in the new Renfrew District library service.

Abstract
Looks at the 2000 Employment Research Unit Annual Conference held at the University of Cardiff in Wales on 6/7 September 2000. Spotlights the 76 or so presentations within and shows that these are in many, differing, areas across management research from: retail finance; precarious jobs and decisions; methodological lessons from feminism; call centre experience and disability discrimination. These and all points east and west are covered and laid out in a simple, abstract style, including, where applicable, references, endnotes and bibliography in an easy‐to‐follow manner. Summarizes each paper and also gives conclusions where needed, in a comfortable modern format.

Abstract
Purpose
Studies have shown that due to the high direct and indirect costs of staff turnover, there is a need for managers to use approaches that engender a feeling that the organisation is fair to its employees and consequently reduce the intention to leave. However, to understand how to apply the research findings and theories from different parts of the world, we need to understand how employees’ perceptions of such factors as ethical leadership and organisational justice are affected by the national culture. Therefore, this study aims to compare the impact of ethical leadership on the intention to leave through justice, loyalty and satisfaction among employees of independent hotels from two Global Leadership and Organizational Behaviour Effectiveness (GLOBE) cultural clusters.
Design/methodology/approach
A total of 1,561 questionnaires were received from independent hotel employees, which were analysed using structural equation modelling. Data were collected in the USA, the UK, Italy and Spain whose national cultures fall into two different GLOBE regional clusters.
Findings
The results show similarities and differences between countries and within and between clusters. No relationship was found between procedural justice and intention to leave in any of the four countries. Ethical leadership had no significant impact on job satisfaction and organisational justice in the UK, which contrasts with results in the other three countries. The study findings also show that distributive justice has a significant relationship with the intention to leave in the USA and the UK (Anglo cluster), whereas no specific relationship was found between these two variables in Italy and Spain (Latin European cluster).
Originality/value
This study contributes to the literature of ethical leadership and its application to the hotel industry in two culturally different GLOBE clusters. This study shows how the relationships between organisational variables are affected by national culture and emphasises the importance for hotel managers of being aware of the specific characteristics of the culture of the country in which they are operating.

Abstract
Downloading and uploading offer labour‐saving advantages and are now accepted as useful options in online searching. All aspects are here considered, from recent technical advances, applications and legal attitudes. There is also a review of current software for downloading. Recent developments mean a trend to higher internal memory and storage capacity, and greater transmission speeds. Packages now offer access to more than one host, give maximum assistance to the user without being menu‐driven and incorporate the latest developments in artificial intelligence. Disadvantages are in the length of time involved in the process and the fact that the legal issue of copyright has not yet been finalised. Database producers have turned to licensing under contract law, but there is still need to rely on user ethics, and the need for a standard permissions form is highlighted.

Abstract
This study explored perspectives of secondary social studies teachers, who reported using live media broad-casts to engage students in an examination of terrorism on 9/11. Specifically, this study queried these teachers’ perceptions of preparedness on 9/11 to engage it as a learning event. Respondents (N=29) in one Mid-Atlantic state who were teaching in secondary social studies classrooms on September 11, 2001 (9/11), were asked to reflect on their level of preparedness to adapt and implement real-time teaching to address unfolding events. A Wilcoxon Signed Ranks Test for matched pairs revealed that respondents’ current perceptions of self-efficacy to teach about an unfolding terrorist act were positively modified by their experiences teaching about terrorism on 9/11 [Z = -4.507, p <.001 (two tailed)]. Respondents reported gains in confidence to teach about terrorism because of their teaching experiences on 9/11. Results add to the small knowledge base on the topic, even as they highlight the need for further research on the classroom response to 9/11.
