From creative destruction to convivial innovation. A post-growth perspective

In this paper, we argue that the notion of Creative Destruction underpinning classical innovation management theory as well as having crystallised into technological determinism and productivism has come to a dead-end. Framing innovation's ultimate goal as the endless pursuit of economic growth is unrealistic if we wish to address pressing environmental challenges. We show that Creative Destruction historically emerged as an ideology from a specific set of values and worldviews at the cradle of Western capitalism and its need for valorisations. Capital valorisation imposes its logic on innovation, definition of needs, consumption, and organisation of work. The mantra of ‘innovate or die’ and its underpinning values represent a hegemonic view on technology aligned with the capitalist mode of production. We argue that a counter-hegemonic view emphasising conviviality and use-value is possible instead and needed to address the environmental and social challenges of our time. We posit that the (re-)emerging mode of production, commons-based peer production (CBPP) has such potential. Indicative cases show that innovation underlined by counter-hegemonic values already exists, albeit in the cracks of the dominant system and in constant danger of co-optation. Governmental institutions need to support these alternative practices of innovation.Axencia Galega de InnovaciónUniversidade de Vigo/CISU

Blockchain research, practice and policy: Applications, benefits, limitations, emerging research themes and research agenda

YesThe blockchain has received significant attention from technology focussed researchers, highlighting its perceived impact and emerging disruption potential, but has been slow to engender any significant momentum within the Information Systems (IS) and Information Management (IM) literature. This study approaches the subject through an IS/IM lens developing the key themes from the blockchain based research via a comprehensive review. This analysis of the body of literature highlights that although few commercial grade blockchain applications currently exist, the technology demonstrates significant potential to benefit a number of industry wide use cases. This study expands on this point articulating through each of the key themes to develop a detailed narrative on the numerous potential blockchain applications and future direction of the technology, whilst discussing the many barriers to adoption. The study asserts that blockchain technology has the potential to contribute to a number of the UN Sustainability Development Goals and engender widespread change within a number of established industries and practices

Breaking the Chains of Open Innovation: Post-Blockchain and the Case of Sensorica

Open innovation is a concept in flux; from the practice of large-scale, internet-mediated collaboration, to a strategic option and business model for firms. However, the scope and breadth of its transformative dynamic is arguably restrained. Despite the theoretical and empirical benefits of openness, established firms face significant challenges deploying the coordination patterns of open innovation communities, further reducing the potential of spill-overs in the supply chain. Viewed differently, open innovation presents more user-centric and responsible innovation paths. These are manifested in the processes and outputs of open innovation by empowering participation and by successfully employing the capacities of user communities. To reap the benefits of open innovation, a rapid reconfiguration of the production and exchange structures is needed in intrafirm and interfirm relations. Sensorica is an open enterprise that achieves such forms of organization and a unique techno-social infrastructure supporting them. It illustrates a potential path that can realize the full potential of open innovation, for users, firms, and the economic system as a whole

A peer-to-peer approach to energy production

a b s t r a c t This paper strives to provide a theoretical study for energy production and distribution. We thus examine and discuss the evolution of energy systems technologies and their impact on the global socio-economic structure. We critically analyze the evolution of the energy production infrastructure and then review the renewable and decentralized energy production technologies, while focusing on the concept of microgrids. Ultimately, we propose an alternative model, inspired by the commons-oriented practices, currently observed in the production of information, that utilizes microgrids in order to create a peer-to-peer energy grid and then discuss the conditions necessary for the "energy commons" to emerge

TMA-Mate: An open-source modular toolkit for constructing tissue microarrays of arbitrary layouts

Biomedical research and quality control procedures often demand a variety of microscopic analysis of numerous formalin-fixed and paraffin-embedded (FFPE) tissue samples from different individuals of both healthy and diseased regions of interest. Depending on the number of samples to be analyzed, conventional processing of each FFPE block separately can be laborious or impracticable. This effort can be drastically reduced by using tissue microarrays (TMAs). TMAs have a wide range of applications and can be considered as a high-throughput method to process up to hundreds of miniaturized tissue samples simultaneously on a single microscopy slide, in order to reduce labor, costs and sample consumption, and to increase results comparability. Several commercial and self-made solutions to fabricate TMAs with varying degrees of automation are available. However, these solutions may not be suitable for every situation, either due to high costs, high complexity, lack of precision or lack of flexibility, especially when diagnostically oriented pathology institutes or laboratories with constrained resources are considered. This article introduces the TMA-Mate, an open-source 3D printable modular toolkit for constructing high-density TMAs of arbitrary layouts, providing an affordable, lightweight, and accessible procedure to implement TMAs into existing histology processing pipelines. Step-by-step demonstration for replicating the Hardware and constructing TMAs are included.Files description:* The folder 'TMA_Mate_FCStd' contains the CAD model as a sigle 'FCStd' file created with the standart unmodified distribution of FreeCAD (version 0.20.1, revision number 29410/Git).* The folder 'TMA_Mate_STL' contains Stereolithography files (.stl) for each individual part of the TMA-Mate and the accessories, created with the standart unmodified distribution of FreeCAD (version 0.20.1, revision number 29410/Git). Compressed archive files (.zip) within this folder contain variants of the indicated 3D printed parts. The stereolithography files for modular parts cannot be offered in all possible variations and are limited to a reasonable selection. The Rack (file 9. R_Rack.zip) is the only part that requires print supports and is therefore provided with and without print supports.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.

Peer to Peer

"Not since Marx identified the manufacturing plants of Manchester as the blueprint for the new capitalist society has there been a more profound transformation of the fundamentals of our social life. As capitalism faces a series of structural crises, a new social, political and economic dynamic is emerging: peer to peer. What is peer to peer? Why is it essential for building a commons-centric future? How could this happen? These are the questions this book tries to answer. Peer to peer is a type of social relations in human networks, as well as a technological infrastructure that makes the generalization and scaling up of such relations possible. Thus, peer to peer enables a new mode of production and creates the potential for a transition to a commons-oriented economy.
