This paper aims to establish the microstructures and the process-structure relationships in duplex stainless steel powders consolidated by selective laser melting (SLM).

A priori data on energy density levels most appropriate to consolidation of duplex stainless steel powders through SLM served as the basis to converge on the laser settings. Experimental designs with varying laser power and scan speeds and test pieces generated allowed metallographic evaluations based on optical and scanning electron microscopy and electro backscatter diffraction analyses.

Duplex stainless steel powders are established for processing by SLM. However, the dynamic point heat source and associated transient thermal fields affect the microstructures to be predominantly ferritic, with grains elongated in the build direction. Austenite precipitated either at the grain boundaries or as Widmanstätten laths, whereas the crystallographic orientations and the grain growth are affected around the cavities. Considerable CrN precipitation is also evidenced.

Duplex stainless steels are relatively new candidates to be brought into the additive manufacturing realm. Considering the poor machinability and other difficulties, the overarching result indicating suitability of duplex powders by SLM is of considerable value to the industry. More significantly, the metallographic evaluation and results of the current research allowed further understanding of the material consolidation aspects and pave ways for fine tuning and establishment of the process-structure-property relationships for this important process-material combination.

The low-temperature sintering of silica glass combined with additive manufacturing (AM) technology has brought a revolutionary change in glass manufacturing. This study aims to carry out in an attempt to achieve precious manufacturing of silicate glassy matrix through the method of slurry extrusion.

A low-cost slurry extrusion modelling technology is used to extrude silicate glassy matrix inks, composed of silicate glass powder with different amounts of additives. Extrudability of the inks, their printability window and the featuring curves of silicate glassy matrix are investigated. In addition, the properties of the low-temperature sintering green part as a functional part are explored and evaluated from morphology, hardness and colour.

The results showed that the particle size was mainly distributed from 1.4 µm to 5.3 µm, showing better slurry stability and print continuity. The parameters were set to 8 mm/s, 80% and 0.4 mm, respectively, to achieve better forming of three-dimensional (3D) samples. Besides, the organic binder removal step was concentrated on 200°C–300°C and 590°C–650°C was the fusion bonding temperature of the powder. The hardness values of 10 test samples ranged from 588 HL to 613 HL, which met the requirements of hard stones with super-strong mechanical strength. In addition, the mutual penetration of elements caused by temperature changes may lead to a colourful appearance.

The custom continuous AM technology enables the fabrication of a glass matrix with 3D structural features. The precise positioning technology of the glass matrix is expected to be applied more widely in functional parts.

“Communism has never concealed the fact that it rejects all absolute concepts of morality. It scoffs at any consideration of “good” and “evil” as indisputable categories. Communism considers morality to be relative, to be a class matter… It has infected the whole world with the belief in the relativity of good and evil.” Aleksandr I. Solzhenitsyn, Warning to the West, 1975.

Although the investigation of brand extension strategies has gained importance, existing research focusses primarily on consumer attitudes to brand extensions, and to date, little research has been made on the luxury market. Moreover, studies on the impact of brand extensions have been limited to explicit measurement methods. Therefore, the aim of this study is to provide new insights by focussing on the change of consumers’ brand perception related to downgrading and upgrading brand extensions strategies in the luxury market based on an implicit association test (IAT).

In this exploratory study context of examining the spontaneous reaction time with reference to the luxury concept by confronting respondents with adequate verbal brand extension stimuli, a ST‐IAT was considered for the empirical tests of these hypotheses.

The study results give evidence that consumers’ perception of an upgrading or downgrading strategy of a brand varies in accordance to these hypotheses. Hence, the reaction time of the H&M subjects decreased after having read the upgrading stimulus whereby, in the case of Karl Lagerfeld, the ST‐IAT reaction times showed that the downgrading information resulted in a weaker association of Karl Lagerfeld with luxury.

The use of implicit measurement methods is becoming increasingly important for assessing consumer reaction to the new product line. Particularly, when luxury brands apply a downgrading strategy, the risks of possible damages to the core brand are much higher than in the case of an upgrade of a basic brand to the luxury or premium segment.

Research has found a subgroup of conservative white males have lower perceptions of risk across a variety of environmental and health hazards. Less research has looked at the views of these “low risk” individuals in group interactions. Through qualitative analysis of a technology deliberation, we note that white men expressing low risk views regarding technologies for energy and the environment also often express high social risks around potential loss of control. We argue these risk perceptions reflect identification with corporate concerns, usually framed in opposition to government and mirroring arguments made by conservative organizations. We situate these views within the broader cultural struggle over who has the power to name and address risks.

Retirement: is it the ‘golden years’ or is it relegation to the ‘human scrapheap’? In reality, it may be either, depending on a multitude of factors interrelated in a complex process. This paper presents a model that describes this process and explains the retirement decision in behavioural terms. The model also shows the interaction between environmental, institutional and individual variables; their impact on retirement; and the impact of retirement upon them.

Neither Marxists and Hegelians nor most supporters of market economies believe that we can really choose an economic system. Historical laws and economic realities undermine our attempts. Explores the problem of predicting any human future and examines background views of human nature which influenced classical economics. Revives Malebranche′s view that man is necessarily an ordering creature. Man must make decisions, but tends towards a natural good which would be instantiated in a social system which reconciled self‐interest and the public interest so that everyone′s rational needs and reasonable desires were given proper weight. In these terms there are choices we can make, especially about how property is to be used and shared.

Based on Geoffrey Harcourt's Palgrave volumes, this review article attempts to picture how, in a Cambridge environment, Keynes's fragmentary monetary theory of production grew organically out of Marshall's equally fragmentary monetary theory of exchange. The dangers associated with Keynes's close links with Marshall are alluded to. Indeed, without taking account of the classical spirit of Sraffa's work, Keynes's monetary theory may quite easily be integrated into the Marshallian‐neoclassical framework of analysis. However, theorising, not literally, but in the spirit of Keynes and Sraffa, within a Ricardian‐Pasinettian framework of vertical integration, opens the way to a Classical‐Keynesian monetary theory of production.
