Building back normal? An investigation of practice changes in the charitable and on-the-go food provision sectors through COVID-19

The COVID-19 pandemic has brought about debates on rethinking food and other socio-technical systems. While swiftly re-establishing normality has understandable appeal in a crisis, the landscape-level changes during the pandemic also hold windows of opportunity to “build back better” and to achieve sustainability transitions. In this article, we ask whether a cycle of disruption and adaptation results either in the rise of more sustainable niche practices or the consolidation of the socio-technical regimes in place. To approach this question, we consider the specific cases of charitable and on-the-go food provision and examine the extent to which COVID-induced adaptations have resulted in debates about, and implementations of, more just and sustainable practices. We draw on systems transitions and practice theoretical approaches to elucidate dynamics and elasticity and thus the effect of socio-technical practice changes. After describing the pre-COVID food regimes, we evaluate organizational practice adaptations during the lockdowns with regard to (1) changing cultural images of food security and provision, (2) socio-technical innovations, and (3) new forms of governance. We find that rather than justifying the public and policy frame of “building back better,” the effect of recovery measures reinforces the socio-technical regimes and omits wider sectoral and societal sustainability challenges such as the systemic reduction of poverty and waste

Zebrafish Peptidoglycan Recognition Proteins Are Bactericidal Amidases Essential for Defense against Bacterial Infections

SummaryPeptidoglycan recognition proteins (PGRPs) are structurally conserved through evolution, but their functions in innate immunity are different in invertebrates and vertebrates. We asked what the functions of PGRPs in fish are and whether they are indispensable for defense against infection because fish are the first vertebrates that developed adaptive immunity, but they still rely solely on innate immunity during early development of embryos. We identified and cloned three zebrafish PGRPs and showed that they are highly expressed in eggs, developing embryos, and adult tissues that contact external environment. Zebrafish PGRPs have both peptidoglycan-lytic amidase activity and broad-spectrum bactericidal activity, which is a unique feature. Furthermore, we demonstrated that in the developing zebrafish embryo, one of these PGRPs is essential for defense and survival during bacterial infections. These data demonstrate an absolute requirement for innate immunity in defense against infections in fish embryos and for a PGRP protein for survival in vertebrates

A novel knowledge repository to support industrial symbiosis

The development of tools and methods supporting the identification of Industrial Symbiosis opportunities is of utmost importance to unlock its full potential. Knowledge repositories have proven to be powerful tools in this sense, but often fail mainly due to poor contextualization of information and lack of general applicability (out of the boundaries of specific areas or projects). In this work, a novel approach to the design of knowledge repositories for Industrial Symbiosis is presented, based on the inclusion and categorization of tacit knowledge as well as on the combination of mimicking and input-output matching approaches. The results of a first usability test of the proposed tool are also illustrated

Business model innovation and transition to a sustainable food system: A case study in the Lisbon metropolitan area

The food systems’ transition towards a sustainable involves structural changes, namely the emphasis on local production, short supply chains, and the preference for organic products. The shift in the agri-food system is taking place through the creation of entirely new businesses and individual farms moving towards organic production. In both cases, the enterprises use a combination of well-established agricultural knowledge and techniques, new scientific knowledge on productive methods and new technological platforms for commercialization. These mixed sources permit the creation of innovative business models (BMs). They exemplify how traditional industries can absorb/generate innovation at technological and organizational levels, and become part of the new knowledge-based era. The study has three objectives: to analyse the emerging agri-food businesses in the Lisbon Metropolitan Area (LMA); to characterize innovative sustainable BMs within the transition dynamics; to reflect on the challenges that the characteristics of the food system pose for the emergence of these BMs. The study is part of an interdisciplinary project on Spatial Planning for Change (SPLACH). The analysis addresses the food system transition in a specific territory, namely the LMA. The paper presents results of the research conducted, focusing on the case of an organic food initiative, Quinta do Oeste.info:eu-repo/semantics/acceptedVersio

Water Managers' Boundary Judgments and Adaptive Water Governance. An Analysis of the Dutch Haringvliet Sluices Case

__Abstract__ In this paper, we explore how managing actors' boundary judgments influence the adaptability of water governance. We approach this question by examining the relationship between the way water managers frame, and act in, complex water issues on the one hand and develop adaptive water governance strategies on the other. We define four categories of boundary judgments made by water managers in order to deal with the complexities in water governance issues. An in-depth case study analysis of an attempt to adjust the management of the water regime in the south-west Delta of the Netherlands is provided in order to reconstruct the water managers' boundary judgments and their impact upon governance strategies used. We found that, most of the time, the water managers involved predominantly made tight boundary judgments. These tight boundary judgments seemed to hamper the mutual learning process among a variety of stakeholders that is needed to realize adaptive water governance. We argue that wide boundary judgments enhance the chance of realizing adaptive practices and build upon exploration, learning, and connection

‘Demand pull’ government policies to support Product-Service System activity: the case of Energy Service Companies (ESCos) in the UK

Product-Service Systems (PSSs) constitute a family of service-based business models designed to satisfy our societal needs in an economically and environmentally sustainable manner. To date however PSS application has remained niche due to a variety of critical barriers. This paper explores how ‘demand pull’ national government policies could support PSS activity by addressing these barriers and cultivating market demand. Lessons are drawn from a case study of how regulatory, economic incentive, informative and procurement policies have supported Energy Service Company (ESCo) activity in the UK; a sub-set of the PSS family focused on energy service provision. Subsequently five policy recommendations are presented to support PSS activity: (1) balancing economic incentives and regulatory disincentives; (2) promoting indirect policy support; (3) redesigning existing market structures; (4) promoting locally-led PSS activity; and (5) creating stable policy frameworks. The paper warns however that national government policy cannot easily address all PSS barriers, such as customer preferences, international developments, technological progress and inherent business model weaknesses, pointing to the need for other complementary solutions. Furthermore, other governance actors beside national government could also implement PSS supporting policies

A Typology of Digital Sharing Business Models: A Design Science Research Approach

The digitally enabled sharing economy, also called the “digital sharing economy” (DSE), has changed patterns of consumption by introducing new choices and channels for provision and receipt of services. The DSE encompasses sharing systems whose business models may vary distinctly from platform to platform. Although business models in the context of the sharing economy have been studied so far, we have observed that the current literature does not provide an approach that covers all the possible business models (in the broadest sense of the term) that (potentially) exist within the scope of the DSE. The present paper, therefore, aims to propose a typology of business models in the DSE that covers a wide space of models – even those which may not involve “business” in the commercial sense. This is achieved through an iterative inductive process based on a design science research approach. The typology can assist in positioning the current and future sharing systems in the DSE by systematically classifying their business models. It is intended to serve as a guiding tool for the sustainability assessment of platforms from both resource and socio-economic perspectives. The present study can also enable researchers and practitioners to capture and systematically analyse digital sharing business models based on a structured, actionable approach
