Wheat supply chain: a comparative study of sustainability issues concerning Brazil and the United Kingdom through Circular Economy lenses.
No full textWheat is one of the most important staple crops globally. It covers more planted area than any other grain and is the most traded major cereal. Therefore, by improving the sustainability of wheat food supply chains, all sustainability aspects are enhanced. One of the most prominent schools of thought regarding sustainability is the Circular Economy (CE). Despite previous works addressing the adoption of CE practices in supply chains ? no previous research addressed how transactions between actors in those supply chains influence the adoption of CE practices. The goals of the CE are to overcome the predominant take-make-dispose model of the contemporary economy favouring a restorative and regenerative system. This thesis differed from past research by analysing a long food supply chain, that is, a supply chain with several links from farmers to market. Furthermore, it focuses on the role that transactions between organisations in the supply chain have in the adoption and diffusion influencers of CE practices. To accomplish this, Transaction Cost Economics (TCE) was used as the supporting theoretical body to the discussions of the transactions between the organisations in the supply chain. The unit of analysis were wheat food supply chains in Brazil and the UK. This research is classified as a qualitative and comparative case study. The investigation identified that all of the CE practices found in the literature with application in the agri-food context were present in the supply chains. Additionally, the material flow was mapped and included potential wastes and by-products flowing in circular loops. There are more similarities than differences in CE practices happening in both countries. The wheat food supply chain transactions have, as a general rule, low asset specificity, mid to high level of uncertainty, long-term contracts, and have varying levels of formalisation. Transaction dimensions have multiple roles within CE diffusion influencers. The research showed that uncertainty in transactions increases barriers to the adoption of a CE practice, especially concerning market issues. Asset specificity has a double directional role, both strengthening and being strengthened by the drivers, particularly consumer demands. Finally, long-term (repeated), formal or informal transactions facilitate the diffusion of CE practices in the supply chain. These roles are fluid and dependent on negotiations that are affected by the power asymmetry between the actors in the buyer-supplier dyads.Tese (Doutorado em Philosophy) - University of Northampton.

No full textTHE ROLE OF LIPID ANTIGENS IN THE PROTECTION AGAINST RHODOCOCCAL PNEUMONIA
No full textThesis (Ph.D.), Department of Veterinary Microbiology and Pathology, Washington State UniversityRhodococcus equi is an actinomycete bacterium that is closely to Mycobacterium tuberculosis. It is also an important cause of pneumonia in young horses worldwide. Like M. tuberculosis, R. equi persists within macrophages and has a cell wall composed of unique microbial lipids. Previous work in our laboratory demonstrates that immune horses carry cytotoxic T lymphocytes (CTL) that recognize and kill R. equi-infected cells in a MHC-unrestricted fashion. Further evidence showing that these cells recognize R. equi lipids provides a potentially important correlation between immune protection and the CD1 system in horses.In this study, we characterized and mapped the equine CD1 gene cluster. It is composed of 13 CD1 genes; seven genes were classified as homologues of human CD1a, two CD1b, one CD1c, one CD1d, and two CD1e, making it the largest CD1 family to date. All but one of the eqCD1 molecules were expressed in all antigen presenting cells investigated. Because R. equi is able to arrest macrophage phagosome maturation between the early endosome and late phagosome, and based on the presence of a sorting motif that is predicted to direct eqCD1a to the early endosome, we hypothesize that the extraordinarily large number of CD1a molecules in horses reflects their role in immunity to R. equi.Because of the predicted expression of a CD1d homologue and published evidence that horse have NKT cells, we have proposed using the synthetic lipid alpha-Galactosyl Ceramide (α-GC) as an adjuvant in an R. equi vaccine. α-GalCer is a potent NKT cell agonist in other species. However, equine CTL stimulated with α-GalCer failed to kill cells infected with R. equi. Likewise, α-GalCer did not increase killing by CTL co-stimulated with R. equi antigen, nor did it induce the proliferation of equine PBMC or increase the proliferation of R. equi stimulated cells. α-GalCer injected intradermally in horses did not increase vasodilation, the recruitment of lymphocytes, or relevant cytokines/markers (e.g. IFN-gamma, granzyme) at sites of injection. These data provide evidence that the horse is well equipped to present lipid-antigens to T cell, however suggest that α-GalCer is unsuitable as a vaccine adjuvant in horses.Department of Veterinary Microbiology and Pathology, Washington State Universit
Understanding Sustainability Innovations Through Positive Ethical Networks
No full textIn this paper, a positive organizational ethics (POE)-based framework is informed by the microfinance and socially responsible investing movements to capture the process of sustainable financial innovations. Both of these movements are uniquely characterized by the formation of positive ethical networks (PENs) to develop sustainability innovations in response to external crises. The crisis–PEN–innovation framework proposed makes four contributions to the POE literature: (1) positions corporate sustainability through a POE lens; (2) formalizes the PEN construction through POE theory; (3) proposes PENs are mobilized to respond to external crises; and (4) demonstrates how PENs facilitate sustainability innovations. The theoretical framework is tested using theory-guided process tracing in the sustainable banking sector to understand how sustainability innovations were realized. The findings are consistent with the crisis–PEN–innovation framework proposed
The Thursday Murder Club: Launching a megabrand author - a publishing case study
No full textIn 2020, the Christmas book charts in the UK made headlines: Barack Obama’s eagerly awaited autobiography, The Promised Land, was beaten to the top spot by The Thursday Murder Club by Richard Osman, a debut cosy crime novel set in a retirement village. Not only did Osman’s book beat the former US president’s expected bestseller, it also broke records, becoming the fastest-selling debut crime novel of all time. Although Osman has a certain level of fame in the UK from his TV appearances on shows such as Pointless, his celebrity status does not entirely explain the novel’s huge sales. This article tracks the acquisition, publication, and promotion journey of The Thursday Murder Club in order to understand the industry and cultural context of its success and to interrogate the role of celebrity in the creation of author brands. The findings suggest that the unexpected scale of the success of the book owed to a number of factors, including in-depth editing by the novel’s agent, editor, and author to tighten up the plot, an extensive and strategic promotional campaign, the pandemic (which drove interest in the book’s genre and themes), and the quality of the writing. We find that the book’s success was accentuated by Osman’s celebrity status rather than being entirely reliant on it. This research adds to the growing scholarship on celebrity authorship by means of an in-depth case study and provides insight into the processes behind publishing a ‘celebrity’ book and launching a megabrand author
