Abstract

Purpose

Recent research has considered robotic machining as a dextrous alternative to traditional CNC machine tools for complex sculptured surfaces. One challenge in using robotic machining is that the stiffness is lower than traditional machine tools, due to the cantilever design of the links and low‐torsional stiffness of the actuators. This paper seeks to examine this limitation, using optimization algorithms to determine the best trajectories for the manipulators such that the stiffness is maximized.

Design/methodology/approach

The issue of low stiffness is addressed with an integrated off‐line planner and real‐time re‐planner. The available manipulator stiffness is maximized during off‐line planning through a trajectory resolution method that exploits the nullspace of the robot machining system. In response to unmodeled disturbances, a real‐time trajectory re‐planner utilizes a time‐scaling method to reduce the tool speed, thereby reducing the demand on the actuator torques, increasing the robot's dynamic stiffness capabilities. During real‐time re‐planning, priorities are assigned to conflicting performance criteria such as stiffness, collision avoidance, and joint limits.

Findings

The algorithms developed were able to generate trajectories with stiffer configurations, which resulted in a reduction in the actuator torques. The real‐time re‐planner successfully allowed the process plan to continue when disturbances were encountered.

Research limitations/implications

Simulations are presented to demonstrate the effectiveness of the approach.

Practical implications

Addressing the limitation of stiffness in serial‐link manipulators will enable robots to become more suitable for machining tasks. The real‐time re‐planning approach will allow robots to become more autonomous during the execution of a given task.

Originality/value

An integrated off‐line and real‐time planning approach has been applied to robotic machining.

Abstract

Discusses the challenges that internal departments face as organizations grow and expand. The Field Museum in Chicago, Illinois, grew significantly over a short period of time, creating considerable problems in the finance department, as staff and systems failed to keep pace with the evolving demands placed by the museum departments. These problems resulted in outdated policies and procedures, unhappy users, and frustrated employees. The finance department needed big changes but had to make them while maintaining vital functions, improving morale, and instituting new policies and procedures. Discusses several key nonprofit management issues, including change management, the role of leadership in a crisis, the challenge of informal personnel networks and knowledge management, and key financial issues facing nonprofit organizations.

Abstract

Halpin and Croft's OCDQ and Aiken and Hayes' bureaucratisation scale were administered to the staffs of 14 State High Schools in an Australian city. The data were subjected to a principal component analysis followed by a varimax rotation. This procedure procured six measures. A diagrammatic representation of the differences revealed between groups within a school is presented. The most significant conclusion is that a high school will include in its staff groups who hold distinct perceptual models of the school's administrative structure and of the principal's leadership quality.

Abstract

The Sanitary Committee of a certain County Council, strong with the strength of recent creation, have lately been animated by a desire to distinguish themselves in some way, and, proceeding along the lines of least resistance, they appear to have selected the Public Analyst as the most suitable object for attack. The charge against this unfortunate official was not that he is incompetent, or that he had been in any way negligent of his duties as prescribed by Act of Parliament, but simply and solely that he has the temerity to reside in London, which city is distant by a certain number of miles from the much favoured district controlled by the County Council aforesaid. The committee were favoured in their deliberations by the assistance of no less an authority than the “Principal” of a local “Technical School”;—and who could be more capable than he to express an opinion upon so simple a matter? This eminent exponent of scientific truths, after due and proper consideration, is reported to have delivered himself of the opinion that “scientifically it would be desirable that the analyst should reside in the district, as the delay occasioned by the sending of samples of water to London is liable to produce a misleading effect upon an analysis.” Apparently appalled by the contemplation of such possibilities, and strengthened by another expression of opinion to the effect that there were as “good men” in the district as in London, the committee resolved to recommend the County Council to determine the existing arrangement with the Public Analyst, and to appoint a “local analyst for all purposes.” Thus, the only objection which could be urged to the employment of a Public Analyst resident in London was the ridiculous one that the composition of a sample of water was likely to seriously alter during the period of its transit to London, and this contention becomes still more absurd when it is remembered that the examination of water samples is no part of the official duty of a Public Analyst. The employment of local scientific talent may be very proper when the object to be attained is simply the more or less imperfect instruction of the rising generation in the rudiments of what passes in this country for “technical education”; but the work of the Public Analyst is serious and responsible, and cannot be lightly undertaken by every person who may be acquainted with some of the uses of a test‐tube. The worthy members of this committee may find to their cost, as other committees have found before them, that persons possessing the requisite knowledge and experience are not necessarily indigenous to their district. Supposing that the County Council adopts the recommendation, the aspirations of the committee may even then be strangled in their infancy, as the Local Government Board will want to know all about the matter, and the committee will have to give serious and valid reasons in support of their case.

Abstract

DR. S. C. ROBERT'S Presidential Address which is printed in the L.A. Record for May and reprinted in the usual separate Proceedings, will be read by all manner of librarians not only for its individual charm but also for a suggestion here and there which may have lasting effects. His major conclusion is that “the spiritual harmony and the intellectual Stability of mankind will Still be largely determined by the reading and writing of books,” whatever may be the triumphs of cinema, wireless and television. This was well worth repeating at a time when we are occupied by visual methods, quite justly, indeed ; if only again to Stress that these must not become an obsession which prevents our seeing that our real purpose is the book. So, too, we may ponder his gentle caveat: “in our laudable efforts towards a perfection of order and classification, there is inevitably a tendency to mistake means for ends, to make our systems our masters rather than our servants.” We know that there is a growing revolt against the intricate simplicities that are being introduced in cataloguing and classification; so intricate, indeed, that except to those who have done careful preparatory reading, writers upon them are completely unreadable. Not the least interesting part of Dr. Roberts's address was his account of early encounters with a library indicator and its attendant difficulties. These may be read as a warning, seeing that most of us have never seen an indicator, and some, because of the losses open access involves, would like to return to what is stupidly called “closed‐access,” a term as sensible as hot ice or dry wet.

Abstract

Hazel Kyrk’s recognised contributions include a shift in analytic focus from production to consumption, pioneering work to measure household production as part of family income, empirical studies of family behaviour, and contributions to policy. But her account of ‘wise’ consumption and its intersection with ‘high’ living standards is not well understood. The three aims of this chapter are to explain ‘wise’ consumption across Kyrk’s three major books, to consider its role in Kyrk’s empirical studies, and to explain why it fell into oblivion. Tackling what Wesley Mitchell described as the ‘most baffling of difficulties’, Kyrk explained what constitutes a family’s ‘good’ in a manner that was critical of mere emulation. Her 1923 book required that wise consumption include new and personal elements. Her 1929/1933 book detailed five qualitative criteria (balance between interests, full and varied experiences, originality, rational sources of satisfaction, and the use of scientific information). But her 1953 book weakened this normative language, reflecting Margaret Reid’s view that Kyrk’s account was too demanding. Although Kyrk felt wise consumption avoided paternalism, her peers disagreed (Hoyt, 1938/1945; Reid, 1938/1945). We close with some problems with Kyrk’s account and a brief consideration of its continuing relevance.

Abstract

Life studies are a rich source for further research on the role of the Afro‐American woman in society. They are especially useful to gain a better understanding of the Afro‐American experience and to show the joys, sorrows, needs, and ideals of the Afro‐American woman as she struggles from day to day.

Abstract

Purpose

This research explored the storytelling (collection, curation and use) in the Cabrach, a remote Scottish glen. This study aims to capture the methodological process of storytelling and curation of heritage knowledge through the lens of the Cabrach's whisky distilling history, a central part of the area's cultural heritage, tangible and intangible. This research was conceptualised as “telling the story of telling the story of the Cabrach”. It was concerned with how the history, heritage, historiography and testimony associated with the parish could be harvested, made sense of and subsequently used.

Design/methodology/approach

The study was epistemological in nature and the research was concerned with how heritage knowledge is gathered, curated and understood. It was built around the collection of knowledge through expert testimony from Colin Mackenzie and Alan Winchester, who have extensively researched aspects of life in the Cabrach. This was done using a series of theme-based but free-flowing conversational workshop involving participants and research team. Issues of trust and authority in the research team were crucial. Data were recorded, transcribed and coded. A conceptual model for heritage storytelling in the Cabrach was developed together with a transferable version for other contexts.

Findings

The research was conceived around identifying the stories of the Cabrach and grouping them into cohesive narrative themes focused on the most important aspect of the glen's history (the development of malt whisky distilling). The research showed how all crucial narratives associated with the Cabrach were interconnected with that malt whisky story. It was concerned with identifying broad thematic narratives rather than the specific detailed stories themselves, but also from a methodological perspective how stories around those themes could be collected, curated and used. It presents the outcome of “expert testimony” oral history conversations and presents a conceptual model for the curation of heritage knowledge.

Practical implications

This paper reports on research which focuses on the confluence of those issues of heritage-led regeneration, intangible cultural heritage, as well as how stories of and from, about and for, a distinctive community in North-East Scotland can be collected, curated and displayed. It presents methodological conceptualisations as well as focused areas of results which can be used to create a strong and inclusive narrative to encapsulate the durable sense of place and support the revival of an economically viable and sustainable community.

Social implications

This conceptual model offers a framework with universal elements (Place, People, Perception) alongside a strong core narrative of storytelling. That core element may vary but the outer elements remain the same, with people and place being omnipresent and the need to build an emotional or visceral connection with visitors being crucial, beyond “telling stories” which might be regarded as parochial or narrowly focused. The model informs how communities and heritage organisations tell their stories in an authentic and proportionate manner. This can help shape and explain cultures and identities and support visitors' understanding of, and connection with, places they visit and experience.

Originality/value

The originality lies in two principal areas, the exploration of the narratives of a singularly distinctive community – the Cabrach – which plays a disproportionately significant role in the development of malt whisky distilling in Scotland; and also in terms of the methodological approach to the collection and curation of heritage storytelling, drawing not on first-hand accounts as in conventional oral history approaches but through the expert testimony of two historical and ethnographic researchers. The value is demonstrating the creation of a conceptual model which can be transferred to other contexts.
