Practicing the Work of a Sustainable Digital Fashion Designer/Maker 4.0: Design of an Organic and Modular Clothing System Based on the Industry 4.0 Approach

Industry 4.0 in the Fashion Industries is having its momentum through the application of digital fabrication technologies encompassing 3D modeling or computing-aided design (CAD), additive manufacturing (i.e. 3D printing), and subtractive manufacturing (i.e. laser cutting, cutting through plotter, and CNC machining) technologies in changing the fashion system in all aspects, from the business models to the creative fashion designer professional skills and activities. In the wave of Industry 4.0 (I4.0), a new design paradigm has been emerging based on the cooperation between digital production and manual expertise: new digital artisans/ fashion designers 4.0 emerged as being able to work on scouting old crafting techniques and updating them through the use of digital fabrication technologies to boost their creative abilities, explore aesthetical possibilities, and start-up new economical businesses. This paper aims to present the status of the art of the digital fashion designer/artisans practices through a preliminary literature review as a baseline to present a case study of hybrid digital fashion craftsmanship focusing on the design and implementation of an organic modular garment system based on the I4.0 approach. The case study will serve to describe the impacts, opportunities, and limitations that digitalization and additive manufacturing techniques could have on fashion design in terms of creativity, design and manufacturing processes, new skills and practices, and sustainability

NASA Proof-of-Concept 1-W(sub e) Stirling Convertor Development for Small Radioisotope Power Systems

Low power Stirling convertors are being developed at NASA Glenn Research Center to provide future small spacecraft with electrical power by converting heat from one or more Light Weight Radioisotope Heater Units (LWRHU). An initial design converts multiple watts of heat to one watt of electrical power output using a Stirling convertor. A variety of mission concepts have been studied by NASA and the U. S. Department of Energy that would utilize low power Radioisotope Power Systems (RPS) for probes, landers, rovers, and repeaters. These missions would contain science instruments distributed across planetary surfaces or near objects of interest where solar flux is insufficient for using solar cells. Landers could be used to provide data such as, radiation, temperature, pressure, seismic activity, and other surface measurements for planetary science and to inform future mission planners. The studies propose using fractional versions of the General Purpose Heat Source or multiple LWRHUs to heat power conversion technologies for science instruments and communication. Dynamic power systems are capable of higher conversion efficiencies, which could enable equal power using less fuel or more power using equal fuel, when compared to less efficient static power conversion technologies. Providing spacecraft with more power would decrease duty cycling of basic functions and, therefore, increase the quality and abundance of science data. Efforts to develop the concept have focused on maturation of a 1-We convertor and controller design and performance evaluation of an evacuated metal foil insulation. A proof-of-concept 1-We convertor, controller, and evacuated metal foil insulation package have been fabricated and are undergoing characterization testing. The current status, findings, and path forward for the effort are explained in this paper

A Cultural Quest: A Study of Organizational Use of New Cultural Resources in Strategy Formation.

Our study was motivated by the growing influence in cultural sociology and organizational research of the view of culture as a “toolkit”, from which individuals draw resources flexibly to develop strategies of action that address different circumstances. To investigate if and how organizations can also use new and diverse cultural resources, we undertook a historical case study of the incorporation of new cultural resources in an organization’s cultural repertoire. In-depth analysis of four rounds of incorporation of new cultural resources led to the development of a robust theoretical model that identifies cultural repertoire enrichment and organizational identity redefinition as two core mechanisms that facilitate the use of new cultural resources for the development of unconventional strategies and strategic versatility. Our model contributes to organizational research novel theoretical understanding regarding the use of cultural resources in strategy formation and change

'My language, my people': language and ethnic identity among British‐born South Asians

This study explores how a group of second generation Asians (SGA) understood and defined language, focusing upon the role they perceived language to have played in their identity. Twelve SGA were interviewed and the data were subjected to qualitative thematic analysis. Four superordinate themes are reported, entitled 'Mother tongue and self', #A sense of ownership and affiliation', 'Negotiating linguistic identities in social space' and 'The quest for a positive linguistic identity'. Participants generally expressed a desire to maintain continuity of self‐definition as Asian, primarily through the maintenance of the heritage language (HL). An imperfect knowledge of the HL was said to have a negative impact upon psychological well‐being. There were ambivalent responses to the perception of language norms, and various strategies were reported for dealing with dilemmatic situations and identity threat arising from bilingualism. Recommendations are offered for interventions that might aid the ‘management’ of bilingualism among SGA

Combining Logics to Transform Organizational Agency: Blending Industry and Art at Alessi

To understand how organizations combine conflicting institutional logics strategically to create and pursue new market opportunities, we conducted an in-depth longitudinal study of the multiple efforts of the Italian manufacturer of household goods Alessi to combine the logics of industrial manufacturing and cultural production. Over three decades, Alessi developed three different strategies to combine normative elements of the two logics, using each strategy to envision and pursue different market opportunities. By combining the logics of industrial manufacturing and cultural production, Alessi was able to envision new possibilities for value creation and to enact them through innovation in product design. The three strategies triggered a common set of mechanisms through which the purposeful combining of logics enabled the pursuit of opportunity, while each strategy structured the process differently. We develop a theoretical model linking the development of recombinant strategies to the dynamic restructuring of organizational agency and the related capacity to create and pursue new market opportunities. Our findings and theoretical insights advance understanding of the processes through which organizations challenge taken-for-granted beliefs and practices to create new market opportunities, use logics as resources to enable embedded agency, and design hybrid organizational arrangements
