The purpose of this paper is to theorize the theory-practice gap and to provide examples of how it currently expresses itself and how it might be addressed to better integrate between the worlds of thought and praxis.

Two empirical examples exemplify how the theory-practice gap is an institutionally embodied social reality. Cultural-historical activity theory is described as a means for theorizing the inevitable gap. An example from the airline industry shows how the gap may be dealt with in, and integrated into, practice.

Cultural-historical activity theory suggests different forms of consciousness to exist in different activity systems because of the different object/motives in the world in which we think and the practical world in which we live. A brief case study of the efforts of one airline to integrate reflection on practice (i.e. theory) into their on-the-job training shows how the world in which pilots think about what they do is made part of the world in which pilots live.

First, in some cases, such as teacher education, institutional arrangements can be made to situate education/training in the workplace. Second, even in the training systems with high fidelity, high validity (transferability) cannot be guaranteed.

The approach proposed provides a theory not only for understanding the theory-practice gap but also the gap that exists even between very high-fidelity (“photo-realistic”) training situations and the real-world praxis full of surprises.

One of the most obvious problems for those involved with disaster relief work is coordination with other teams in the field, with headquarters, with the mother organization in the home country and having to deal with unanticipated situations. The central dilemma appears to be this: disaster relief workers either have the knowledge to know what to do or the authority to do it. Seldom, however, are the local knowledge of what to do and the authority to do it located in the same person. This mismatch creates instability which generates pressure for change. Such change occurs through what we describe as “renegotiations of authority” – where people or teams who are not officially in charge take authority to act, because they know what to do and how urgent it is to do it. This paper presents the concept of renegotiations of authority through cycles of breaking down qualitative data obtained from disaster workers from multiple organizations and countries.

National Engineers' Week takes place annually during the week of George Washington's birthday. Washington, best known as a soldier and stateman, was also a surveyor and road builder. The National Society of Professional Engineers began this tradition in 1950 with a two‐page article in The American Engineer. The society promoted Engineers Week on a national level beginning in 1951. February and March issues of The American Engineer in 1951 discussed the early celebrations of this week. The society's history (Robbins) also gives insights about the creation of this special week. Although the National Society of Professional Engineers initiated this week, other engineering organizations became involved later. At the present time, many organizations participate in the celebration. Each year, the National Society of Professional Engineers plans a particular theme for the week.

IN an address at the dedication of Brooks Library, Brattle‐borough, Mellen Chamberlain made the statement that “before 1700 there was not in Massachusetts, so far as is known, a copy of Shakespeare's or of Milton's poems.” In taking account of the cultural background of colonial America, it is both interesting and instructive to compare this statement with Macaulay's appraisal of seventeenth century England, to the effect that “few of the knights of the shire had libraries as good as may now be found in a servant's hall or in the back parlour of a shop‐keeper. An Esquire passed among his neighbours for a great scholar if Hudibras or Baker's Chronicle, Tarlton's Jests and The Seven Champions of Christendom lay in his hall window among the fishing rods and fowling pieces.” In the light of the foregoing, it is not to be expected that the colonies would produce much by way of literature. As a matter of fact, colonial literature is largely disappointing, but the remarkable thing about it is that there is as much of it as there is, and that it is as good as it is.

The purpose of this paper is to offer direct tests of the effectiveness of renaming vocational education and training (VET) in enhancing the image and popularity of the subject. Although many proponents of renaming argue that the word “vocational” is associated with lower levels of skills and knowledge and should therefore be supplemented by better recognised words, empirical evidence regarding the effectiveness of this strategy is scant.

This study exploits a rare policy change in Hong Kong, where VET was renamed as vocational and professional education and training (VPET) and conducted an original survey experiment of 1,004 parents in the city to test if the new name would improve respondents' perceptions of the subject.

The findings reveal a complex picture regarding the effects of renaming. Although renaming does not seem to improve the overall popularity of vocational education, it may widen the support base for vocational education by diluting its class character. Specifically, while attitudes toward VET are significantly and negatively correlated with family income, no such association is found in regard to VPET.

This paper offers the first direct and comprehensive test of the effectiveness of renaming vocational education – a popular policy suggestion in many countries. Its findings complicate conventional expectations and contribute to the study of educational preferences in advanced economies.

The findings of this study have lightened the focal research areas in maintenance planning and scheduling. These also served as effective guidelines for future studies in this area. This research, therefore, contributes in fulfilling the gap by carrying out an SLR of contemporary research studies in the area of models for maintenance planning and scheduling. At present, SLR rooted in BA has not been carried focusing on a survey over models for maintenance planning and scheduling. SLR uses advanced scientific methodologies from BA tools to unveil thematic structures.

We have systematically reviewed over 1,021 peer-reviewed journal articles. Advanced contemporary tools from Bibliometric Analysis (BA) are used to perform a Systematic Literature Review (SLR). First, exploratory analysis is presented, highlighting the influential authors, sources and region amongst other key indices. Second, the large bibliographical data is visualized using co-citation network analyses, and research clusters (themes) are identified. The co-citation network is extended into a dynamic co-citation network and unveils the evolution of the research clusters. Last, cluster-based content analysis and historiographical analysis is carried out to predict the prospect of future research studies.

BA tools first outlined an exploratory analysis that noted influential authors, production countries, top-cited papers and frequent keywords. Later, the bibliometric data of over 1,021 documents is visualized using co-citation network analyses. Later, a dynamic co-citation analysis identified the evolution of research clusters over time. A historiographical direct citation analysis also unveils potential research directions. We have clearly observed that there are two main streams of maintenance planning and scheduling applications. The first has focused on joint maintenance and operations on machines. The second focused on integrated production and maintenance models in an echelon setting for unrealizable production facilities.

There are many literature review-based research studies that have contributed to maintenance scheduling research surveys. However, most studies have adopted traditional approaches, which often fall short in handling large bibliometric data and therefore suffer from selection biases from the authors. As a result, in this area, the existing reviews could be non-comprehensive. This study bridges the research gap by conducting an SLR of maintenance models, which to the best of our knowledge, has not been carried out before this study.

The brief announcement that the Government had accepted that there should be regulations on open date marking of food, to come into effect in 1975, will come as no surprise. It is a timely reminder of what public pressure can achieve these days; how sustained advocacy and publicity by interested sectors of society—magistrates, local authorities, public health workers, consumer groups—can secure legislative changes which, in this case, run counter to trade opinions and the recommendation originally made by the Food Standards Committee that such a proposal was not practical and the existing law was an adequate protection. This was stated in the FSC Report on Food Labelling of 1964, although there was no indication of the evidence reviewed or that the subject had been considered very deeply; it was, after all, only a small fraction of the problem of food labelling control. It was also stated in this Report that in certain cases, date‐stamping of food could give to purchasers a false sense of security, “not justified by the conditions under which the food has been kept since manufacture”.
