Abstract

Purpose

This study aims to address challenges in the Laser Powder Bed Fusion process of polymers, focusing on the considerable amount of unsintered powder left post-printing. The objective is to understand the altered properties of this powder and find solutions to improve the process, reduce waste and explore reusing reprocessed powder.

Design/methodology/approach

A novel methodology is used to generate reprocessed powder without traditional printing, reducing time, cost and waste. The approach mimics the ageing effects during the printing process, providing insights into particle size distribution and thermal behaviour.

Findings

Results reveal insights into artificial ageing, showing an 8.2% decrease in particle size (60.256–69.183 µm) and a 9.1% increase in particle size (17.378–19.953 µm) compared to unsintered powder. Thermal behaviour closely mirrors used powders, with variations in enthalpy of fusion (−0.55% to 2.69%) and degree of crystallinity (0.19% to 2.64%). The proposed methodology produces results that differ from those due to printing under 3% from a thermal point of view. The new process reduces the time needed for aged powder, contributing to cost savings and waste reduction.

Originality/value

The study introduces a novel method for reprocessed powder generation, deviating from traditional printing. The originality lies in artificially ageing powders, providing comparable results to actual printing. This approach offers efficiency, time savings and waste reduction in the Laser Powder Bed Fusion process, presenting a valuable avenue for further research.

Abstract

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

Abstract

In the aftermath of the Enron scandal, the critics of free enterprise have blamed this system for inflated and out of control executive salaries, particularly those of the chief executive officer (CEO). The present paper defends the marketplace against these charges. In section I we argue that the market has passed the Enron test with flying colors. Section II gives the background of the financial situation relating to CEO salaries. Sections III and IV are devoted to, respectively, the tax court and the appellate court; section V looks at the reaction of the former to the latter; and in section VI we defend the “independent investor” test. We look at this issue from a political economic perspective in section VII and conclude in section VIII.

Abstract

Michael E. Brown's book, The Concept of the Social in Uniting the Humanities and Social Sciences, demonstrates that prominent attempts to account for the social dimension of human affairs rely on an unstated notion of a “course of activity,” that is diametrically opposed to the conceptualization of sociality that is presumably intended to realize it. I want to focus on the idea of a “course of activity” in order to locate his work in and clarify its importance to the development of dialectical reason from Heraclitus through Hegel and beyond. Of special importance is the bearing of his research on the critique of contemporary theories of agency and sociality, and, since considerable attention has been paid, in this regard, to the arts and humanities, some of what I will say about this refers to art and its avant-garde moments—-particularly in my work on Dada and Brown's account of two avant-garde theatrical performances. 

This chapter examines what is entailed by separating agency from individuality and what it means for the idea of a “course of activity,” (going on) and its relation to the concept of sociality. This also bears on questions of ontology, as Brown's course of activity is generative and nonrepeatable. The course of activity and nonrepeatability are linked to both avant-garde practice and theoretical notions that reframe our temporal understandings. These include the avant-garde of dada and surrealism, and the reformulations of bourgeois time of Jean Duvignaud, Walter Benjamin, Ernst Bloch, and Jean-Paul Sartre. The question raised here is that of a teleological understanding—how we link the present course of activity with future events.

Abstract

The Bureau of Economics in the Federal Trade Commission has a three-part role in the Agency and the strength of its functions changed over time depending on the preferences and ideology of the FTC’s leaders, developments in the field of economics, and the tenor of the times. The over-riding current role is to provide well considered, unbiased economic advice regarding antitrust and consumer protection law enforcement cases to the legal staff and the Commission. The second role, which long ago was primary, is to provide reports on investigations of various industries to the public and public officials. This role was more recently called research or “policy R&D”. A third role is to advocate for competition and markets both domestically and internationally. As a practical matter, the provision of economic advice to the FTC and to the legal staff has required that the economists wear “two hats,” helping the legal staff investigate cases and provide evidence to support law enforcement cases while also providing advice to the legal bureaus and to the Commission on which cases to pursue (thus providing “a second set of eyes” to evaluate cases). There is sometimes a tension in those functions because building a case is not the same as evaluating a case. Economists and the Bureau of Economics have provided such services to the FTC for over 100 years proving that a sub-organization can survive while playing roles that sometimes conflict. Such a life is not, however, always easy or fun.

Abstract

Purpose

The purpose of this paper is to analyse the evolution of “push” marketing in the confectionery industry in Britain during the 1930s. It examines the interplay between a manufacturer and advertising agency in creating advertising for cocoa and chocolate.

Design/methodology/approach

A survey of the literature examines the uses of health and well-being in the design of advertising in Britain between the wars. The records of Rowntree and its main advertising agency, J Walter Thompson, are used to examine the themes and tactics used in advertising for cocoa and Aero chocolate bars during the 1930s.

Findings

The paper emphasises the different ways in which health and nutrition was used in advertising for the two products. The campaigns of the 1930s built on earlier use of these themes. J Walter Thompson looked for ways of presenting commodities as “new and improved” and their role extended into pressing for changes to production methods and the nature of products. Themes of modernity, sexuality and lifestyles all featured, confirming conclusions of earlier studies. However, targeting of mothers and of different age and gender groups indicated that market segmentation was used extensively via print media and tailored advertising messages.

Originality/value

Although Cadbury, Rowntree and confectionery have been studied in depth before, this paper emphasises their role in applying new advertising ideas to everyday items. It points to the influence of advertising on the mass of consumers compared to the middle- and upper-income groups targeted in the marketing of houses, motor-cars and new consumer durables.
