Abstract

Purpose

The purpose of this paper is to evaluate the performance of cutting fluid applied by minimum quantity technique when milling AISI 4140 steel with TiAlN coated cemented carbide inserts.

Design/methodology/approach

The vegetable oil based cutting fluid evaluated was applied through a nozzle at the centre of the tool holder under vaporized conditions with a flow rate between 0 (dry cutting) and 200 ml/h, at 50 ml/h increments. Tool wear (based on maximum flank wear, VBmax), surface roughness parameters (Ra and Rt) and burr formation (length of burr, h) were recorded and evaluated. Scanning electron microscope images and energy dispersive X‐ray analysis of the worn tools show adhesion as the dominant wear mechanism.

Findings

Encouraging tool performance was recorded when milling AISI 4140 steel due to improved lubrication and cooling at the cutting interfaces. Increase in cutting fluid flow rate improves tool life with gradual reduction of the surface roughness parameters and negligible influence on the burr length generated.

Practical implications

Results can be immediately applied on the shop floor.

Originality/value

The results show the improvement in tool wear after increase of the flow rate of the cutting fluid, applied by minimum quantity technique.

Abstract

Provides snapshots of several research and development actions aimed at addressing the question of what characterizes competent command of a fire ground incident. Looks at two aspects of this question: how to describe fire ground command (what is it that fire ground commanders do?) and what qualities should be looked for in prospective fire ground commanders (what are the underlying aptitudes or competences required for effective fire ground command?). Brings together data drawn from cognitive task analysis, teamwork analysis, a recent model of incident command developed for the London Fire Brigade (LFB), job analysis focusing on aptitude requirements for fire ground commanders, and assessment centres designed for selecting fire crew commanders and senior LFB officers.

Abstract

This Food Standards Committee Report has been with us long enough to have received careful appraisal at the hand of the most interested parties — food law enforcement agencies and the meat trade. The purposes of the review was to consider the need for specific controls over the composition and descriptive labelling of minced meat products, but the main factor was the fat content, particularly the maximum suggested by the Associaton of Public Analysts, viz., a one‐quarter (25%) of the total product. For some years now, the courts have been asked to accept 25% fat as the maximum, based on a series of national surveys; above that level, the product was to be considered as not of the substance or quality demanded by the purchaser; a contention which has been upheld on appeal to the Divisional Court.

Abstract

The dates for the conference of the International Federation for Documentation to be held in London in September 1961 have now been settled finally. They differ slightly from those already notified to members of Aslib, who are now requested to note that the first public session will take place at 2.30 p.m. on Tuesday 12th September. The last public session will take place during the afternoon of Friday 15th September and it is hoped to arrange a conference dinner on the evening of the same day. Aslib members who are making early reservations of accommodation in London for the conference should make a special note of this timetable.

Abstract

The experimental parliamentary subsidy on knights' fees and freehold incomes from lands and rents of 1431 was the only English direct lay tax of the Middle Ages which broke down. As such, this subsidy has a clear historiographical significance, yet previous scholars have tended to overlook it on the grounds that parliament's annulment act of 1432 mandated the destruction of all fiscal administrative evidence. Many county assessments from 1431–1432 do, however, survive and are examined for the first time in this article as part of a detailed assessment of the fiscal and administrative context of the knights' fees and incomes tax. This impost constituted a royal response to excess expenditures associated with Henry VI's “Coronation Expedition” of 1429–1431, the scale of which marked a decisive break from the fiscal-military strategy of the 1420s. Widespread confusion regarding whether taxpayers ought to pay the feudal or the non-feudal component of the 1431 subsidy characterized its botched administration. Industrial scale under-assessment, moreover, emerged as a serious problem. Officials' attempts to provide a measure of fiscal compensation by unlawfully double-assessing many taxpayers served to increase administrative confusion and resulted in parliament's annulment act of 1432. This had serious consequences for the crown's finances, since the regime was saddled with budgetary and debt problems which would ultimately undermine the solvency of the Lancastrian state.

Abstract

While dealing with samples as they arrive daily, and sometimes hourly, throughout the year, the Public Analyst gets little opportunity of reflecting on the general trend of his work, its significance in the life of the community, and upon the changes in conditions and customs that may have some bearing on its development. The occasion to take a few hours off from the daily routine in writing this Annual Report provides an appropriate opportunity to look at the work in some sort of perspective, to review briefly the past and to cast a glance towards the future. The concept of Public Analysts occurred in the 1860's, when there was no dearth of evidence that all was not as well as it should be in the matter of foods and drugs on sale to the public; but reform in these matters made a slow start for the simple reason that only isolated practitioners were available who possessed the necessary competence and experience. Bearing in mind the simple character of their apparatus, the limited range of their reagents, and the almost complete absence of technical literature, we, their successors, take off our hats to the early pioneer Public Analysts. With little encouragement and for small reward they plodded away to expose to day‐light the crude forms of adulteration then being practised and commenced the process of debunking the unwarranted claims made for many preparations on sale. They developed a science of analytical chemistry at their own expense, devised their own processes, and produced their own literature, thus beginning the slow process that ultimately made possible the greatly improved standards prevailing today in the quality of the foods and drugs available to the public. So much for the reasonably glorious past. With regard to the present, although the Public Analyst is far from complacent about the existing state of affairs, and is in fact in many ways dissatisfied and highly critical of his organisation, he nevertheless realises that there is much to be thankful for. For one thing, the public, who, curiously enough, in the past have shown a morbid fascination for worthless products as long as they were attractively packed and glamorously advertised, are now becoming more enlightened in matters of food. They dislike having their illusions shattered, but they are beginning to appreciate the bearing that pure food has upon their health, and honest food on their pockets. As the Public Analyst is virtually responsible for bringing about these things, he has come to be more acceptable, and his existence is less begrudged than H.M. Inspector of Taxes, for instance. In the second place, as one consequence of the increasing knowledge of nutrition, important sections of the Ministry of Food have been deputed to bring up to date the law on food questions, to introduce definite standards of composition, and to fix limits for impurities. The Ministry has also dealt with the question of labelling and advertising, and has, in fact, done some excellent work in this direction. The result is that a Public Analyst no longer works, as it were, in vacuo, having to pit his own opinion against that of the defence, but has a good deal of official backing which enables him to assess his problems with more precision. In the third place, the Royal Institute of Chemistry has regularised the standard of competence of Public Analysts, and has played its part in ensuring that facilities are provided for the training of necessary recruits to the profession. There are, on the other hand, some notable weak points in the present position which occasion concern. Generally speaking, Public Analysts have fallen sadly behind in the economic scale, and frequently have the depressing experience of seeing promising young analysts go off at a tangent into industry, teaching, and other professions, just as they are accumulating the specialised experience which is a necessary complement to their basic training to make them good future Public Analysts. There is one outstanding technical anomaly which has been commented upon a good deal recently. The mass production of foodstuffs accompanied by nationally‐wide advertising has resulted in identically similar articles being obtainable almost anywhere between Land's End and John O'Groats. As the situation is at present, every Public Analyst is liable to sample the same product, which is not only inefficient in that it entails duplication of work, but, where prosecutions are made, may lead to uneven standards of justice being applied in different parts of the country. The manufacturers have to attempt to clear themselves in the eyes of the law many times for what is virtually the same offence. This is typical of a number of matters which Public Analysts themselves are conscious of and hope to see put right. The next few years may possibly see radical changes in the organisation. Some revolutionary suggestions are being put forward that the status quo should be scrapped and replaced by a few regional laboratories, but the matter needs very careful consideration. In theory laboratories organised in larger units would make for greater efficiency, and, indeed, only those beyond a certain minimum size could justify all the necessary equipment. . But the work of the Public Analyst has always had, and still retains, a good deal of local character, and matters can often be put right by personal contact where official action from a remote centre would not achieve the desired effect. The Analyst should begin to lose the “one guinea per sample ” mentality and be regarded as a consultant to his local authority on all chemical matters. Given a direct approach to the various committees with which he comes into contact, adequate accommodation and equipment, and sufficient suitably trained staff to make some degree of specialisation possible, the present organisation has many years of useful work before it. Problems concerning water supply, sewage disposal, atmospheric pollution, and similar matters, will always arise; while short of some radical change in human nature the percentage of adulterated samples of food and drugs, either as a result of fraud, misunderstanding, or accident, will not go down to nil. Until that desirable state of affairs comes about, the public will need, and possibly demand, expert protection of the kind which is at present associated with the Public Analyst.

Abstract

Within the past 20 years hiking and backpacking have enjoyed rapid growth among Americans as favorite outdoor activities. From 1965 to 1977 the number of hikers almost tripled, from 9.9 million to 28.1 million, while national forest visitor days among hikers and mountaineers increased from 4 million in 1966 to 11 million in 1979. Accompanying this growth in interest has been a boom in books about the sport. These include both “how‐to‐do‐it” volumes and guides to specific geographical areas. Each year brings another spate of books, yet to this compiler's knowledge no bibliography of hiking guides to the Rocky Mountains, one of North America's premier outdoor regions, has yet been attempted. This bibliography is an effort to correct that situation.

Abstract

In this study, we use the well-researched and validated Big Five model of personality traits to examine accounting students’ career interests in auditing. Using the person-job fit literature as a springboard for our study, we investigate the influence of accounting students’ personality traits on their career interests in auditing using a research survey. We uncover a general “trait gap” (i.e., lack of fit) between accounting students’ own personality traits and their perceptions of the ideal auditor, which presents implications for workplace readiness. Additionally, analysis focusing on students who particularly want to work in auditing indicates that those with more auditing work experience are more likely to identify auditing as their preferred job. Furthermore, results indicate that accounting students higher on openness to experience tend to view auditing jobs as more desirable. Finally, accounting students who prefer the auditing career path perceive the ideal auditor as extroverted, agreeable, and open to experience. We extend prior findings in the accounting education literature surrounding personality traits and their impact on student career choices. Because advising students for a career path suiting their traits and talents is important for each student and the accounting profession, our study’s insights into the “matching process” add value to career advising.

Abstract

In his inauguration speech of 1961, John F. Kennedy, the first Catholic and youngest-ever holder of the office of US President, famously exhorted citizens to ‘Ask not what your country can do for you; ask what you can do for your country.’ At the time, few would have interpreted this as a call for open innovation or even citizen crowdsourcing: neither the language nor the architecture then existed for either. But the sentiment he expressed marked the beginning of a campaign of citizen engagement in developing ideas for government. It was, in effect, the first national exhortation for the crowdsourcing of ideas, and Kennedy’s words have subsequently been adapted by Jeff Howe for the modern crowdsourcing context.

Citizen crowdsourcing is now well-established. This chapter sets out to assess how successful it has been as a mechanism for finessing original and meaningful ideas that advance social goals. We look briefly at leading examples of crowdsourcing for social good. We also look at the underlying factors that support it, including the knowledge and input solicited from the crowd; the crowd’s willingness to participate; and the mechanisms through which the crowd can engage. We trace the idea and practice of crowdsourcing back to Socrates in ancient Athens. We look at prosocial behaviour, exploring selected annals of public intellectuals, including Emerson. We examine citizen science as a forerunner of crowdsourcing, then move into the business strategy of open innovation and, finally, we arrive at crowdsourcing for social good in various guises. In conclusion, we explore what has been learned from initiatives that can now be considered current best practice in this area.
