Patterns of Practice - Interdisciplinary Negotiation of Cultural Complexity through Practice-Based Methods in Informatics
(2022)
Following the principle of knowing through making, this thesis discusses development and application of a practice-based methodology for construction of digital artefacts within
cultural contexts. It addresses the epistemological diversity and complexity inhering within interdisciplinary projects, suggesting methodological devices able to navigate the variegated disciplinary landscape present within respective development projects. The conceptual pair complexity/complication acts as theoretical point of reference ...

The Implications of Feedback Frequency for Employee Creativity
(2022)
Managers are still floundering when they have to decide on the optimal level of feedback frequency; either when they consider themselves as a source of feedback, but also when they shape the feedback environment of their employees, e.g., by allowing more (or less) frequent customer feedback. Furthermore, given that feedback is a time-consuming task, managers might be reluctant to provide feedback frequently, foregoing a potentially powerful lever for increasing employee creativity. Ultimately, clarifying the ambiguities ...

Holzdesign trifft Kunststofftechnik
(2022)
Werkstoffverbunde aus Holzgeweben in einer thermoplastischen Matrix verbinden die Idee des textilen Holzbaus mit der Faserverbundtechnologie. In einem Projekt werden Fassadenelemente aus solchen Wood Textile Composites hergestellt. Dabei spielt neben den mechanischen Anforderungen auch die gestalterische Seite und die Akzeptanz der zukünftigen Nutzer eine wichtige Rolle.

Effects of aging on the stress-induced martensitic transformation and cyclic superelastic properties in Co-Ni-Ga shape memory alloy single crystals under compression
(2022)
Co-Ni-Ga shape memory alloys attracted scientific attention as promising candidate materials for damping applications at elevated temperatures, owing to excellent superelastic properties featuring a fully reversible stress-strain response up to temperatures as high as 500 °C. In the present work, the effect of aging treatments conducted in a wide range of aging temperatures and times, i.e. at 300–400 °C for 0.25–8.5 h, was investigated. It is shown that critical features of the martensitic transformation are strongly ...

Making transdisciplinarity happen: Phase 0, or before the beginning
(2022-06-21)
Both within science and society, transdisciplinary approaches are increasingly employed to address today’s sustainability challenges. Often transdisciplinary research processes are structured in three core phases: a) problem identification and formation of a common research object; b) co-production of solution-oriented and transferable knowledge; c) embedding co-produced knowledge through transdisciplinary reintegration. In all phases of this ideal-typical model, the involvement of non-academic actors is essential ...

Diffusion of Material Flow Cost Accounting and its Contribution to Sustainable Development
(2022)
This thesis aims to analyze how further take-up of Material Flow Cost Accounting (MFCA) in practice can be encouraged to support sustainable development. To achieve the aim of the thesis, three studies on MFCA are conducted at multiple levels. The first study provides a better understanding of MFCA application at the corporate level in developing countries, which are characterized by rapid structure transformation leading to serious environmental problems. The second study considers the contextual and transformational ...

Values as leverage points for sustainability transformation: two pathways for transformation research
(2022-08-13)
The burgeoning literature on sustainability transformation agrees that values play a key, albeit unelucidated, role on the transformation research agenda. Recent literature linking values and transformation increasingly points toward the hypothesis that values may act as leverage points for sustainability transformation. However, how transformation research can engage with values as leverage points remains a critical knowledge gap. Here, I argue that transformation research needs to distinguish between two modes of ...

Modification of self-reinforced composites (SRCs) via film stacking process
(2022-02-25)
This work presents the mechanical behavior of self-reinforced composites (SRCs) manufactured and modified via film stacking. For modification, interleaved films made of polypropylene (PP), a thermoplastic elastomer and a polyolefin engage were combined in different ways to induce the elastic modifier into the matrix material. The content of modifier was also varied in two ways. First, the films were produced out of a single material and second out of a compound. So, the same content of modifier was implemented in two ...

Influences on the mechanical properties of SRCs in a combined compacting and back injecting process
(2022-03-03)
In this research paper, the effects of the combined compacting and back-injection process to produce back-injected self-reinforced composites on the mechanical properties of the self-reinforced composites (SRCs) are investigated. For this purpose, the parameters barrel temperature, time of injection and holding pressure were varied for the back injection. Tensile and bending tests were carried out on the SRCs. The results show that the mechanical properties depend to a large extent on the process parameters. The ...
