The following bibliography focuses mainly on programs which can run on IBM microcomputers and compatibles under the operating system PC DOS/MS DOS, and which can be used in online information and documentation work. They fall into the following categories:

We have conducted a study of academic faculty use of databases for research, their need for evaluative guides to databases, and the appropriateness of currently‐available guides. Although the response rate was low (19%), the follow‐up survey suggested only a minimal non‐response bias. Our findings suggest that academic faculty are typically unaware of the range of databases available and few recognize the need for databases in research. Of those faculty who do use databases, most delegate the searching to a librarian or an assistant, rather than performing the searches themselves. We identified thirty‐nine database guides; these tend to be descriptive rather than evaluative.

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.

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.

This paper explores the potential influence and consequences of corpora te branding on mountain resort destinations. It examines the extent to which corporations emphasize “placefulness” in the branding of their tourism products and services, as well as the degree to which they intentionally match their brands with values held by other destination stakeholders. “Placefulness” refers to the relative extent to which corporate branding strategies reinforce a destination's “sense of place” The findings suggest that a corporate as opposed to a community approach to branding is emerging in many tourism destinations. This has resulted in some significant redefinition of destination identities to reflect the changing needs of markets and corporations. Probably the most apparent identity shift in mountain communities brought on by corporate influence has involved the repositioning of many areas from being ski resorts to becoming four season destination resorts.

This review reports on the current state and the potential of tools and systems designed to aid online searching, referred to here as online searching aids. Intermediary mechanisms are examined in terms of the two stage model, i.e. end‐user, intermediary, ‘raw database’, and different forms of user — system interaction are discussed. The evolution of the terminology of online searching aids is presented with special emphasis on the expert/non‐expert division. Terms defined include gateways, front‐end systems, intermediary systems and post‐processing. The alternative configurations that such systems can have and the approaches to the design of the user interface are discussed. The review then analyses the functions of online searching aids, i.e. logon procedures, access to hosts, help features, search formulation, query reformulation, database selection, uploading, downloading and post‐processing. Costs are then briefly examined. The review concludes by looking at future trends following recent developments in computer science and elsewhere. Distributed expert based information systems (debis), the standard generalised mark‐up language (SGML), the client‐server model, object‐orientation and parallel processing are expected to influence, if they have not done so already, the design and implementation of future online searching aids.

This paper reviews the history of separate online system interfaces, leading to efforts to develop expert systems for searching databases, particularly for end users, and introduces the research in such expert systems. Appended is a bibliography of sources on interfaces and expert systems for online retrieval.

Presents a review on implementing finite element methods on supercomputers, workstations and PCs and gives main trends in hardware and software developments. An appendix included at the end of the paper presents a bibliography on the subjects retrospectively to 1985 and approximately 1,100 references are listed.

The purpose of this paper is to propose that black churches in the USA are best suited to curtail the rising incidence of suicide, and suicide ideation among African-American adolescents. Presently, little is known about the best preventive practices and mental healthcare interventions for the black adolescents assailed by suicide and suicidal ideation.

A review of the extant literature was conducted to understand and synthesize the current knowledge base about suicide rates among African-American adolescents. To retrieve and review relevant literature that focussed on suicide among African-American adolescents and the preventive roles of black churches the authors searched the following databases: PsychINFO, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Social Work abstracts, and Google Scholar.

Findings indicate that black churches could implement, and profusely replicate the lay health advisors and HAVEN models to successfully mitigate the rate of suicide among black adolescents. In addition it was found that the gatekeeper suicide prevention program model also holds promise for suicide prevention among black adolescents in black churches.

The result of this research synthesize is limited to African-American adolescents and may not be generalizable to other minority adolescents’ experiencing suicidal challenges. Furthermore, future research should utilize qualitative research methodologies to document lived experiences of African-American adolescents who are survivors of suicide attempts with a view to preventing suicide and suicidal ideation among black adolescents.

Healthcare professionals, and policy makers, are provided a panoramic view of culturally competent and spiritually sensitive prevention interventions within black churches that are most appropriate for reducing suicide rates among minority black adolescents.

This paper provides an introduction to the use of n‐grams in textual information systems, where an n‐gram is a string of n, usually adjacent, characters extracted from a section of continuous text. Applications that can be implemented efficiently and effectively using sets of n‐grams include spelling error detection and correction, query expansion, information retrieval with serial, inverted and signature files, dictionary look‐up, text compression, and language identification.
