Computer‐aided acquisition and logistic support (CALS), dealing with the automation and integration of all functions and processes that make up the many aspects of acquisition and logistic support of weapons systems, is explored with particular reference to the area of standard generalised mark‐up language (SGML).

Logisticians will have to face up to CALS — Computer‐aided Acquisition and Logistics Support systems. An expert explains why.

The following annotated bibliography of materials on orienting users to libraries and on instructing them in the use of reference and other resources covers publications from 1981. A few items from 1980 have been included because information about them was not available in time for the 1980 listing. A few items have not been annotated because the compiler was unable to secure copies of these items.

The term ‘obsolescence’ occurs frequently in the literature of librarianship and information science. In numerous papers we are told how most published literature becomes obsolete within a measurable time, and that an item receives half the uses it will ever receive (‘half‐life’) in a few years. ‘Obsolescence’ is however very rarely defined, and its validity, interest, and practical value are often assumed rather than explained. Before reviewing studies on ‘obsolescence’, therefore, it is necessary to look at the concept and to identify the reasons why it should be of interest.

Pamela Graddon recently left BLRDD, having been promoted to head of the Industrial Property Section in the British Library's Science Reference and Information Service (SRIS). Her responsibilities in BLRDD for information technology are now being dealt with by Derek Greenwood who previously workedin the SRIS. Dr Elizabeth Dron, who joined BLRDD earlier this year, has left the British Library on promotion to take up a post in the Department of Environment.

In 1933 two books on competitive structure were published. One, extracted from a Harvard PhD filed six years earlier, dealt with the workings of the competitive process. Seeking not to supplant, but to supplement Marshall, this book by E. H. Chamberlin focused on an effort involving the use of a diagrammatic apparatus to highlight certain fundamental relationships between variables in the competitive process. It did not analyse real firms but nor did it attempt to pretend that such were irrelevant, and to concentrate on positions of competitive equilibrium only. It dealt with problems of arrival at equilibrium, false trading, and a whole variety of issues relevant to an actual competitive process. Supervised by Allyn Young, it drew on a wide range of references and showed evidence of the kind of thorough scholarly preparation which has always been characteristic of the best American PhDs.

Nobody concerned with political economy can neglect the history of economic doctrines. Structural changes in the economy and society influence economic thinking and, conversely, innovative thought structures and attitudes have almost always forced economic institutions and modes of behaviour to adjust. We learn from the history of economic doctrines how a particular theory emerged and whether, and in which environment, it could take root. We can see how a school evolves out of a common methodological perception and similar techniques of analysis, and how it has to establish itself. The interaction between unresolved problems on the one hand, and the search for better solutions or explanations on the other, leads to a change in paradigma and to the formation of new lines of reasoning. As long as the real world is subject to progress and change scientific search for explanation must out of necessity continue.

The purpose of this paper is to propose the use of case studies in teaching an undergraduate course of Internet for Business in class, based on the revised Bloom’s taxonomy. The study provides the empirical evidence about the effect of case-based teaching method integrated the revised Bloom’s taxonomy on students’ incremental learning, measured by the four constructs: knowledge application, higher-order thinking, practice evaluation knowledge and knowledge improvement.

In this study, learning activities associated with the revised taxonomy-based learning strategy were proposed to support the development of higher-level cognitive skills. Revised application scale, higher-order thinking scale, practice evaluation knowledge scale and knowledge improvement scale were used to measure students’ perception of skills corresponding to their level of application, analysis, evaluation and creation, respectively. After completing each task pertinent to case studies, students were encouraged to complete the survey questionnaire. Structural equation modelling (SEM) was employed to examine the relationships between constructs. Students participate in a course where case studies are employed as the main learning activities to promote higher-order thinking. Upon completing the course, they fill in a survey to evaluate the four constructs of incremental learning: level of knowledge application, higher-order thinking, practice evaluation knowledge and knowledge improvement. The relationships between the four constructs are then examined using SEM.

Analysis reveals that with the use of case-based learning activities, knowledge application creates a positive impact on higher-order thinking. Higher-order thinking has positive influence on practice evaluation knowledge. Eventually, practice evaluation knowledge produces a positive effect on knowledge improvement. The results show the desired effects of incremental learning.

The case studies designed for teaching the Internet for Business course might not be suitable in terms of content for other courses, which limit the implication of the findings.

The key implication is that cognitive process is enhanced by using case studies where learning activities are designed, based on the revised Bloom’s taxonomy.

The paper offers a comprehensive perspective on incremental learning where students’ knowledge of Internet for Business moves developmentally towards the higher-order cognitive process dimension of the revised Bloom’s taxonomy.

Life studies are a rich source for further research on the role of the Afro‐American woman in society. They are especially useful to gain a better understanding of the Afro‐American experience and to show the joys, sorrows, needs, and ideals of the Afro‐American woman as she struggles from day to day.
