Learning can be viewed as a communication process that puts the learner in contact with concepts created by others. A result of communication is that an act of interpretation starts, which invokes a process of conceptualization. According to Mayes, successful conceptualization will need the support of learning activities. Hence, machine mediated communication is important for creating online e‐Learning opportunities; not only for relaying communication content, but also for supporting the cognitive processes associated with the necessary learning activities required for conceptualization. In Laurillard’s conversational theory, a communication loop should be established between learners and teachers. The articulation element in this loop is necessary for engaging the learner in a collaborative activity, which is essential for developing further the conceptualization process. This paper discusses the acts of communication, conceptualization and articulation within a machine mediated multimodal communication, and it proposes a framework within which a supporting set of cognitive activities can be developed.

This chapter describes five disciplinary domains of research or lenses that contribute to the design of a team tutor. We focus on four significant challenges in developing Intelligent Team Tutoring Systems (ITTSs), and explore how the five lenses can offer guidance for these challenges. The four challenges arise in the design of team member interactions, performance metrics and skill development, feedback, and tutor authoring. The five lenses or research domains that we apply to these four challenges are Tutor Engineering, Learning Sciences, Science of Teams, Data Analyst, and Human–Computer Interaction. This matrix of applications from each perspective offers a framework to guide designers in creating ITTSs.

The institution of food and cookery exhibitions and the dissemination of practical knowledge with respect to cookery by means of lectures and demonstrations are excellent things in their way. But while it is important that better and more scientific attention should be generally given to the preparation of food for the table, it must be admitted to be at least equally important to insure that the food before it comes into the hands of the expert cook shall be free from adulteration, and as far as possible from impurity,—that it should be, in fact, of the quality expected. Protection up to a certain point and in certain directions is afforded to the consumer by penal enactments, and hitherto the general public have been disposed to believe that those enactments are in their nature and in their application such as to guarantee a fairly general supply of articles of tolerable quality. The adulteration laws, however, while absolutely necessary for the purpose of holding many forms of fraud in check, and particularly for keeping them within certain bounds, cannot afford any guarantees of superior, or even of good, quality. Except in rare instances, even those who control the supply of articles of food to large public and private establishments fail to take steps to assure themselves that the nature and quality of the goods supplied to them are what they are represented to be. The sophisticator and adulterator are always with us. The temptations to undersell and to misrepresent seem to be so strong that firms and individuals from whom far better things might reasonably be expected fall away from the right path with deplorable facility, and seek to save themselves, should they by chance be brought to book, by forms of quibbling and wriggling which are in themselves sufficient to show the moral rottenness which can be brought about by an insatiable lust for gain. There is, unfortunately, cheating to be met with at every turn, and it behoves at least those who control the purchase and the cooking of food on the large scale to do what they can to insure the supply to them of articles which have not been tampered with, and which are in all respects of proper quality, both by insisting on being furnished with sufficiently authoritative guarantees by the vendors, and by themselves causing the application of reasonably frequent scientific checks upon the quality of the goods.

Research on coping at work has tended to adopt a between-person perspective, producing inconsistent findings on well-being outcomes. This focus on interindividual differences is in contrast to many theories that position coping as process, hence, as an intraindividual process that unfolds over time in response to job stressors and appraisals. The authors propose that focusing more on the within-person coping processes and integrating them with learning perspectives has the potential to advance our understanding. More specifically, coping behavior and well-being can be seen as an outcome of current and past learning processes. In this chapter, the authors discuss three mechanisms that explain how coping processes can produce positive versus negative effects on well-being, and how coping can be integrated into a learning framework to explain these pathways. First, the stress process entails encoding and evaluation of the situation and, as a consequence, deployment of suitable coping behavior. Over and above the efforts that have to be invested to understand the stressful situation, the coping behavior itself also requires time and energy resources. Second, coping behavior likely co-occurs with learning processes such as reflection, exploration, and exploitation. These learning processes require further time and cognitive resources. Third, although coping behaviors and their accompanying learning processes have the potential to drain resources at the within-person level, they can also build up interindividual coping resources such as a broader repertoire and coping flexibility. These between-level differences equip employees to deal with future stressors.

There is a huge amount of information and data stored in publicly available online databases that consist of large text files accessed by Boolean search techniques. It is widely held that less use is made of these databases than could or should be the case, and that one reason for this is that potential users find it difficult to identify which databases to search, to use the various command languages of the hosts and to construct the Boolean search statements required. This reasoning has stimulated a considerable amount of exploration and development work on the construction of search interfaces, to aid the inexperienced user to gain effective access to these databases. The aim of our paper is to review aspects of the design of such interfaces: to indicate the requirements that must be met if maximum aid is to be offered to the inexperienced searcher; to spell out the knowledge that must be incorporated in an interface if such aid is to be given; to describe some of the solutions that have been implemented in experimental and operational interfaces; and to discuss some of the problems encountered. The paper closes with an extensive bibliography of references relevant to online search aids, going well beyond the items explicitly mentioned in the text. An index to software appears after the bibliography at the end of the paper.

The First International Conference on Bibliographic Access in Europe attracted delegates from twenty‐seven countries to the University of Bath in September 1989. The conference is the successor to the earlier conferences ‘Online Public Access to Library Files’ which were held at the same location in 1983, 1985 and 1987. The changed focus of the conference reflected Philip Bryant's, (Director of the Centre for Bibliographic Management at Bath) view that a lot had been written about OPACs and that they ought to be viewed in the wider context of bibliographic access, which in turn was now an international issue. The decision to focus on Europe was timely, given moves towards greater integration within the European Community. The international nature of the gathering was emphasised by the provision of simultaneous translation between English, French and German, and papers presented by speakers from more than ten countries. The major themes of the conference were the role of networks and CD‐ROMs in providing bibliographic access, and standards associated with both the contents of records and their transfer.

Examines Just‐in‐Time (JIT) from its evolution as a Japanese concept through to a review of its philosophy and implementation. Cites several techniques of implementation. Includes a review of the early work of various researchers and practitioners. Concludes that JIT is a very effective manufacturing philosophy which is universal in nature encompassing all aspects of manufacturing. Suggests a few deficiencies in current literature.

Using data from a retail chain of 193 bakery shops that underwent downsizing, we study the effects of two types of downsizing announcements – closure or sale to another operator – on sales in the affected shops, and how these effects are moderated by job security perceptions. On average, sales in the affected shops go down by 26% after a closure announcement and by 7% after a sale announcement. Sales decline more sharply in shops where employees had higher job security perceptions before the announcement. Our findings are consistent with psychological contract theory: a breach of an implicit contract promising job security in exchange for work effort results in a reciprocal effort withdrawal. We rule out several alternative explanations to our findings.
