Samples of sandwiches were taken from all petrol filling stations in the Bolton area selling such foodstuffs. These were bacteriologically examined and, when the results were obtained, all the petrol stations were visited and advice was given where improvements could be made. Resampling was carried out and the results were compared with the initial samples. The second set of results indicated a significant improvement in microbial flora. Further recommendations were made where necessary and it was possible to produce a Code of Practice from the results obtained.

Sociologists of crime and deviance have devoted considerable time and effort, in recent years, to the study of deviants' accounts of their activities. There are good reasons why students of deviance in particular should be interested in what can be learned from their subjects' explanations of their social practices. Actors are normally called to account for or to explain their activities precisely when these actions are seen by significant others to be in some sense “unreasonable”. Moreover, accounts are central to the processes of law. The purpose of legal judgements is to attribute or withold responsibility. In order to assess an individual's guilt, where criminal activities are concerned, lawyers, judges, and juries pose such questions as: “Did the defendant perform an illegal act?”; “if so, can he or she explain his or her actions in reasonable terms?”; “Was the act in question pre‐meditated?” (that is, “motivated”); and, perhaps most important of all “What is the relationship between the accused's account of his or her involvement in an act, and their real involvement?”

Cutting tool wear is known to affect tool life, surface quality, cutting forces and production time. Micro-milling of difficult-to-cut materials like Inconel 718 leads to significant flank wear on the cutting tool. To ensure the respect of final part specifications and to study cutting forces and tool catastrophic failure, flank wear (VB) has to be controlled. This paper aims to achieve flank wear prediction during micro-milling process, which fills the void of the commercial finite element software.

Based on tool geometry structure and DEFORM finite element simulation, flank wear of the micro tool during micro-milling process is obtained. Finally, experiments of micro-milling Inconel 718 validate the accuracy of the proposed method for predicting flank wear of the micro tool during micro-milling Inconel 718.

A new prediction method for flank wear of the micro tool during micro-milling Inconel 718 based on the assumption that the wear volume can be assumed as a cone-shaped body is proposed. Compared with the existing experiment techniques for predicting tool wear during micro-milling process, the proposed method is simple to operate and is cost-effective. The existing finite element investigations on micro tool wear prediction mainly focus on micro tool axial wear depth, which affects size accuracy of machined workpiece seriously.

The research can provide significant knowledge on the usage of finite element method in predicting tool wear condition during micro-milling process. In addition, the method presented in this paper can provide support for studying the effect of tool flank wear on cutting forces during micro-milling process.

The purpose of this study is to realize the multi-objective optimization for MRR and surface roughness in micro-milling of Inconel 718.

Taguchi method has been applied to conduct experiments, and the cutting parameters are spindle speed, feed per tooth and depth of cut. The first-order models used to predict surface roughness and MRR for micro-milling of Inconel 718 have been developed by regression analysis. Genetic algorithm has been utilized to implement multi-objective optimization between surface roughness and MRR for micro-milling of Inconel 718.

This paper implemented the multi-objective optimization between surface roughness and MRR for micro-milling of Inconel 718. And some conclusions can be summarized. Depth of cut is the major cutting parameter influencing surface roughness. Feed per tooth is the major cutting parameter influencing MRR. A number of cutting parameters have been obtained along with the set of pareto optimal solu-tions of MRR and surface roughness in micro-milling of Inconel 718.

There are a lot of cutting parameters affecting surface roughness and MRR in micro-milling, such as tool diameter, depth of cut, feed per tooth, spindle speed and workpiece material, etc. However, to the best our knowledge, there are no published literatures about the multi-objective optimization of surface roughness and MRR in micro-milling of Inconel 718.

This study presents an original empirically based conceptual framework representing mobile microbusiness founders' experiences when converting to a franchise business model that links individual-level variables to a sociomaterial process.

An exploratory interpretive research design produced this framework using data from the enterprise development narratives of mobile franchisors who had recently converted their mobile microbusinesses to a franchise business model.

The emergent framework proposes that franchisor’s conversion experience involves substantial identity work prompted by an identity dilemma originating in a conflict between role expectations and franchising operational demands. This dilemma materializes during franchise document creation and requires some degree of “identity undoing” to ensure business continuity. By acting as boundary-objects-in-use in the conversion process, the franchise documents provide a sociomaterial foundation for the business transition and the development of a viable franchisor identity.

There is scant literature addressing the startup experiences of mobile microbusiness franchisors. The study was therefore exploratory, producing a substantive conceptual framework that will require further confirmatory studies.

By proposing that conversion to a franchise business model is experienced as an identity transformation coupled to a sociomaterial process centred on system documentation, this original empirically based conceptual framework not only addresses a gap in the individual-level literature on franchise development but also provides a framework to direct new research and discussions between intending franchisors and their professional advisors about person–enterprise fit.

The conceptual framework is the first to address franchisors' experience of transitioning any type of microbusiness to a franchise business model.

Scholars frequently address the dyadic relationships between leaders and followers without observing the simultaneity of leadership and followership roles, particularly evident in middle managers. Their implicit and explicit challenges are the foci of this paper.

The purpose of this paper is to explore the pluralist contours of Canadian management “knowledge” using the discourse “official” bilingualism – the English and French languages – to understand the impact of socio-historical-political differences on the development of management knowledge production.

Drawing upon an archival collection of management textbooks as historical data, the authors critically explore and analyze the development of Canadian “schools” and management theory. Using narrative analysis and critical hermeneutics, the paper considers the socio-historical-political context of the various “Canadian” scholars that sought to establish a unique business academy distinct but paradoxically akin to the management schools in the USA.

Mirroring the struggle of Francophones in a dominant English imperative, French management textbooks appeared decades later than English titles. When French texts began to disseminate, it remained in the shadows of American management ideologies.

As only Canadian organizational behavior texts published within the previous 50 years were used as data in this study, it may be incautious to draw broader conclusions. The empirical element of this research relied upon convenience sampling of textbooks.

Management educators weld a considered level of socio-political power that they may or may not knowingly possess, especially in terms of selecting a textbook and other course materials. Regardless of background, management students are somewhat a “tabula rasa;” open to learning new content to make sense of the world. This “open state” places a great deal of responsibility on the professorate in shaping management students’ theoretical understanding of everyday life in organizations. The authors suggest practitioners be reflexive, aware of how textbooks serve as an important vehicle in education that in times past, have promoted or reified mono-cultural agendas.

The research in this paper builds on recent research that considers the role of socio-historical-political context in how management knowledge and theory is performed, as well as contributes to understanding textbooks in how they may shape a pluralist account of Canadian management “knowledge”.

Gives the author’s own variations of his work on a similar vein but quite different in its own way to Laud Humphreys. Revisits Humphrey’s ideas on the “breastplate of righteousness”, finding them insightful in explaining a particular bad experience of being fired from an American University, which was run by Jesuit priests, although he has now forgiven them for what transgressed there.

Competition is a prominent topic of discussion among academics and practitioners; yet the relevant literatures in management and psychology lack a consistent definition to describe this phenomenon. Consequently, much of the mixed results concerning competition's impact on attitudes and performance might be due to conceptual differences about the construct. A survey administered in a laboratory setting demonstrated individuals perceive different types of competition, and these different types had different impacts on attitudes and behavior. One type of competition identified here, the opportunity for informal competition, draws from a vast literature in social psychology—using social comparisons to evaluate performance. These results support broadening the definition of competition and expanding future research investigation efforts. Informal social competition can potentially benefit efforts to effectively direct and enhance motivation.

Substance use tends to be overlooked in nursing training. As a possible consequence, many nurses harbour ill‐informed or even negative attitudes towards drug and alcohol users. The upshot can be poor care. In a bid to tackle this problem, a group of students developed a peer‐led workshop by encouraging open debate on issues associated with illicit drug use and access to healthcare for those with substance misuse problems. What ensued was an open and frank debate that increased awareness and the thirst for more knowledge.
