This paper aims to present guidelines for using streaming multimedia tutorials in academic library instruction.

Research in cognitive psychology, education and librarianship is synthesized and its application to the design of library screencast or multimedia tutorials is discussed.

Guidelines are presented on determining when multimedia is needed, how to make sure multimedia tutorials are clear and understandable, how to include interactivity effectively, how to promote critical thinking, and how to design interfaces and tutorial structure based on levels of student knowledge.

Screencasts are a relatively new form of library instruction. Guidelines in this paper are summarized in a checklist that can be used when designing screencasts or multimedia tutorials.

Usability testing can play a valuable role in improving the effectiveness of online information literacy instruction, while forming a core component in a wider assessment plan. This article aims to discuss the usability testing of an online information literacy tutorial for freshman undergraduates at Wilfrid Laurier University Library.

Two librarians, working to fulfill an important mandate of the Library's Information Literacy Task Force, defined goals, created and implemented a modest, though effective, approach to usability assessment.

The testing provided detailed information on the ease of use of the tutorial, as well as users’ satisfaction levels with content and design. These findings informed subsequent revisions and enhancements to the online tutorial.

Student evaluation questionnaires distributed subsequent to the tutorial overhaul indicate the success of usability testing in the development of a more effective learning tool.

The latest information from the magazine chemist is extremely valuable. He has dealt with milk‐adulteration and how it is done. His advice, if followed, might, however, speedily bring the manipulating dealer before a magistrate, since the learned writer's recipe is to take a milk having a specific gravity of 1030, and skim it until the gravity is raised to 1036; then add 20 per cent. of water, so that the gravity may be reduced to 1030, and the thing is done. The advice to serve as “fresh from the cow,” preferably in a well‐battered milk‐measure, might perhaps have been added to this analytical gem.

There are very few individuals who have studied the question of weights and measures who do not most strongly favour the decimal system. The disadvantages of the weights and measures at present in use in the United Kingdom are indeed manifold. At the very commencement of life the schoolboy is expected to commit to memory the conglomerate mass of facts and figures which he usually refers to as “Tables,” and in this way the greater part of twelve months is absorbed. And when he has so learned them, what is the result? Immediately he leaves school he forgets the whole of them, unless he happens to enter a business‐house in which some of them are still in use; and it ought to be plain that the case would be very different were all our weights and measures divided or multiplied decimally. Instead of wasting twelve months, the pupil would almost be taught to understand the decimal system in two or three lessons, and so simple is the explanation that he would never be likely to forget it. There is perhaps no more interesting, ingenious and useful example of the decimal system than that in use in France. There the standard of length is the metre, the standard of capacity the cubic decimetre or the litre, while one cubic centimetre of distilled water weighs exactly one gramme, the standard of weight. Thus the measures of length, capacity and weight are most closely and usefully related. In the present English system there is absolutely no relationship between these weights and measures. Frequently a weight or measure bearing the same name has a different value for different bodies. Take, for instance, the stone; for dead meat its value is 8 pounds, for live meat 14 pounds; and other instances will occur to anyone who happens to remember his “Tables.” How much simpler for the business man to reckon in multiples of ten for everything than in the present confusing jumble. Mental arithmetic in matters of buying and selling would become much easier, undoubtedly more accurate, and the possibility of petty fraud be far more remote, because even the most dense could rapidly calculate by using the decimal system.

Attachment Theory can be regarded as central to the concept of relational security. There is a paucity of research examining the coherence of this construct for ward-based staff. The paper aims to discuss these issues.

Five female nurses from the acute admission and assessment ward of a UK medium secure unit acted as participants. Semi-structured interviews were conducted, and inductive thematic analysis was applied.

Six themes; “staff-service user relationships”, “staff diversities”, “service user backgrounds”, “variability in service users’ presentations”, “service users with personality disorder are problematic” and “nurses do not use attachment” emerged from the data. The nurses used heuristic models of attachment-related behaviour and they lacked knowledge of constructs associated with Attachment Theory.

Acute admissions may not be representative of all treatment contexts. Traditional models of attachment style may have only limited relevance in forensic services.

Limited knowledge and confidence in the nurses regarding how Attachment Theory might apply to service users is interesting because it may limit the extent to which care, treatment and risk management might be informed by an understanding of service user representations of therapeutic relationships. Training and educational interventions for nurses that enhance understanding of personality development and attachment styles are warranted.

The importance of nurses for achieving relational security is emphasised and the adequacy of their training is questioned.
