TL;DR: The Coalition for Epidemic Preparedness Innovations has developed and is continuously maintaining an overview of the global landscape of COVID-19 vaccine development activity, which includes vaccine development programmes reported through the WHO's authoritative and continually updated list, along with other projects identified from publicly available and proprietary sources.
Abstract: CoV-2, the coronavirus that causes COVID-19, was published on 11 January 2020, triggering intense global R&D activity to develop a vaccine against the disease. The scale of the humanitarian and economic impact of the COVID-19 pandemic is driving evaluation of nextgeneration vaccine technology platforms through novel paradigms to accelerate development, and the first COVID-19 vaccine candidate entered human clinical testing with unprecedented rapidity on 16 March 2020. The Coalition for Epidemic Preparedness Innovations (CEPI) is working with global health authorities and vaccine developers to support the development of vaccines against COVID-19. To facilitate this effort, we have developed and are continuously maintaining an overview of the global landscape of COVID-19 vaccine development activity. Our landscape database includes vaccine development programmes reported through the WHO’s authoritative and continually updated list, along with other projects identified from publicly available and proprietary sources (see Supplementary Box 1). The landscape provides insights into key characteristics of COVID-19 vaccine R&D and serves as a resource for ongoing portfolio management at CEPI. We have also shared our landscape information with others in the global health ecosystem to help improve coordination in the COVID-19 outbreak response and enable global resources and capabilities to be directed towards the most promising vaccine candidates.

TL;DR: It is suggested that in order to support the emergence of learning spaces that are resource‐rich and conducive to learning, educational contexts and pedagogical arrangements must provide both the framing conditions and also the flexibility and permeability required to access the wider ecologies of resources made available through digital technologies.
Abstract: This paper argues for the need to develop a relational, emergent and plural understanding of learning spaces. We take an ecological perspective on learning, which allows us to conceptualize learning spaces as (co‐)constructed by learners; emerging through learners' practices, interactions and activities; and facilitated by pedagogical arrangements. In the co‐construction of spaces for learning, tapping into various ecologies of resources—whether intellectual, relational or digital material—becomes an organic, iterative, agentic endeavour for learners. This paper proposes a set of principles to synthesize this conceptualization and facilitates an understanding of such emergent learning spaces. An empirical illustration extracted from a collaborative student project in software engineering education contributes to grounding the conceptual argument and provides a clarifying example. Ultimately, this contribution suggests that in order to support the emergence of learning spaces that are resource‐rich and conducive to learning, educational contexts and pedagogical arrangements must provide both the framing conditions and also the flexibility and permeability required to access the wider ecologies of resources made available through digital technologies. Practitioner NotesWhat is already known about this topic Learning spaces can be individual or collective.Physical space is an important element that can facilitate or hinder learning.Technology can contribute to hosting learning spaces (eg, online).What this paper adds A potential new conceptualization drawing on an ecological perspective on learning.Insights into how learning spaces are customized versions of the learners' intellectual, relational or digital‐material resources available in various contexts.Examples of how learning spaces are constitutive through learners' individual or collective practices, based on affordances provided by pedagogical designs.Propositions on how pedagogical designs can provide learners with opportunities to access wider ecologies of resources made available through digital technologies.Implications for practice and/or policy Teachers need support to develop pedagogical designs that support learners in creating their own learning spaces.Helping students to create their learning spaces requires guidance, which must be facilitated by appropriate institutional infrastructures and conditions.Professional learning approaches are needed to build teachers' knowledge and capacities to support students.Institutional arrangements must be open to change.

TL;DR: In this paper , the authors provide a Europe-wide inventory with over 10,000 initiatives and 16,000 production units in 29 countries, focusing on the past 20 years, allowing cross-country statistical analysis, supporting the elicitation of empirical insights capable of extending beyond the perspective of single case studies.
Abstract: Numerous case studies show that citizens engage in various ways in renewable and low carbon energy projects, thereby contributing to the sustainable energy transition. To date, however, a systematic and cross-country database on citizen-led initiatives and projects is lacking. By performing a major compilation and reviewing copious data sources from websites to official registries, we provide a Europe-wide inventory with over 10,000 initiatives and 16,000 production units in 29 countries, focusing on the past 20 years. Our data allow cross-country statistical analysis, supporting the elicitation of empirical insights capable of extending beyond the perspective of single case studies. Our data also align with ongoing efforts to implement two EU Directives that aim at strengthening the active role of citizens in the energy transition. While the focus of our data collection is on Europe, the data and methodology can contribute to the global analysis of citizen-led energy action.

TL;DR: In this paper, an expanded analysis of the public mission mandate of the Greek higher education sector is presented, based upon the heuristic presuppositions of behavioral economics, and the authors argue that its operational conditions of financial scarcity may entail broader and inadvertent ramifications, namely the depletion of cognitive resources and the propagation of narrow mental frames in the pursuit of a public mission.
Abstract: Relying upon the heuristic presuppositions of behavioral economics, this study seeks to offer an expanded analysis of the public mission mandate of the Greek higher education sector. The examination outlines and parses qualitative evidence issued from the Greek Ministry of Education, and in particular from the hitherto untranslated document A Strategy for Higher Education in Greece: 2016–2020, in conjunction with a growing body of scholarship on the challenges of cultivating public trust in the Greek social landscape. The discussion negotiates the position of the Greek higher education system as a system of sustainable social prosperity and argues that its operational conditions of financial scarcity may entail broader and inadvertent ramifications, namely, the depletion of cognitive resources and the propagation of narrow mental frames in the pursuit of a public mission.

TL;DR: In this article, a short discussion aims to delineate the discourse similarities between Tuchman's landmark contribution Wannabe U: Inside the Corporate University and the latest White Paper Kultur for kvalitet i hoyere utdanning by Norway's Ministry of Education.
Abstract: This short discussion aims to delineate the discourse similarities between Tuchman’s landmark contribution Wannabe U: Inside the Corporate Universityand the latest White Paper Kultur for kvalitet i hoyere utdanning by Norway’s Ministry of Education. Initially, it reviews in detail Tuchman’s book by means of providing a critical foil for articulating the rhetorical and political identity of an inspiring higher education institution. Next, it outlines the rudiments of the Norwegian White Paper and argues for the striking similarities between the two documents with regard to the subsisting discourses of competitiveness. The discussion concludes with a criticism of the dearth of actionable and evidence-based solutions regarding the lexis of higher education’s institutional competitiveness.

TL;DR: This review discusses current evidence regarding the pathophysiology, transmission, diagnosis, and management of COVID-19, the novel severe acute respiratory syndrome coronavirus 2 pandemic that has caused a worldwide sudden and substantial increase in hospitalizations for pneumonia with multiorgan disease.
Abstract: Importance The coronavirus disease 2019 (COVID-19) pandemic, due to the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused a worldwide sudden and substantial increase in hospitalizations for pneumonia with multiorgan disease. This review discusses current evidence regarding the pathophysiology, transmission, diagnosis, and management of COVID-19. Observations SARS-CoV-2 is spread primarily via respiratory droplets during close face-to-face contact. Infection can be spread by asymptomatic, presymptomatic, and symptomatic carriers. The average time from exposure to symptom onset is 5 days, and 97.5% of people who develop symptoms do so within 11.5 days. The most common symptoms are fever, dry cough, and shortness of breath. Radiographic and laboratory abnormalities, such as lymphopenia and elevated lactate dehydrogenase, are common, but nonspecific. Diagnosis is made by detection of SARS-CoV-2 via reverse transcription polymerase chain reaction testing, although false-negative test results may occur in up to 20% to 67% of patients; however, this is dependent on the quality and timing of testing. Manifestations of COVID-19 include asymptomatic carriers and fulminant disease characterized by sepsis and acute respiratory failure. Approximately 5% of patients with COVID-19, and 20% of those hospitalized, experience severe symptoms necessitating intensive care. More than 75% of patients hospitalized with COVID-19 require supplemental oxygen. Treatment for individuals with COVID-19 includes best practices for supportive management of acute hypoxic respiratory failure. Emerging data indicate that dexamethasone therapy reduces 28-day mortality in patients requiring supplemental oxygen compared with usual care (21.6% vs 24.6%; age-adjusted rate ratio, 0.83 [95% CI, 0.74-0.92]) and that remdesivir improves time to recovery (hospital discharge or no supplemental oxygen requirement) from 15 to 11 days. In a randomized trial of 103 patients with COVID-19, convalescent plasma did not shorten time to recovery. Ongoing trials are testing antiviral therapies, immune modulators, and anticoagulants. The case-fatality rate for COVID-19 varies markedly by age, ranging from 0.3 deaths per 1000 cases among patients aged 5 to 17 years to 304.9 deaths per 1000 cases among patients aged 85 years or older in the US. Among patients hospitalized in the intensive care unit, the case fatality is up to 40%. At least 120 SARS-CoV-2 vaccines are under development. Until an effective vaccine is available, the primary methods to reduce spread are face masks, social distancing, and contact tracing. Monoclonal antibodies and hyperimmune globulin may provide additional preventive strategies. Conclusions and Relevance As of July 1, 2020, more than 10 million people worldwide had been infected with SARS-CoV-2. Many aspects of transmission, infection, and treatment remain unclear. Advances in prevention and effective management of COVID-19 will require basic and clinical investigation and public health and clinical interventions.

TL;DR: The mRNA-1273 vaccine as discussed by the authors is a lipid nanoparticle-encapsulated mRNA-based vaccine that encodes the prefusion stabilized full-length spike protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes Covid-19.
Abstract: Background Vaccines are needed to prevent coronavirus disease 2019 (Covid-19) and to protect persons who are at high risk for complications. The mRNA-1273 vaccine is a lipid nanoparticle-encapsulated mRNA-based vaccine that encodes the prefusion stabilized full-length spike protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes Covid-19. Methods This phase 3 randomized, observer-blinded, placebo-controlled trial was conducted at 99 centers across the United States. Persons at high risk for SARS-CoV-2 infection or its complications were randomly assigned in a 1:1 ratio to receive two intramuscular injections of mRNA-1273 (100 μg) or placebo 28 days apart. The primary end point was prevention of Covid-19 illness with onset at least 14 days after the second injection in participants who had not previously been infected with SARS-CoV-2. Results The trial enrolled 30,420 volunteers who were randomly assigned in a 1:1 ratio to receive either vaccine or placebo (15,210 participants in each group). More than 96% of participants received both injections, and 2.2% had evidence (serologic, virologic, or both) of SARS-CoV-2 infection at baseline. Symptomatic Covid-19 illness was confirmed in 185 participants in the placebo group (56.5 per 1000 person-years; 95% confidence interval [CI], 48.7 to 65.3) and in 11 participants in the mRNA-1273 group (3.3 per 1000 person-years; 95% CI, 1.7 to 6.0); vaccine efficacy was 94.1% (95% CI, 89.3 to 96.8%; P Conclusions The mRNA-1273 vaccine showed 94.1% efficacy at preventing Covid-19 illness, including severe disease. Aside from transient local and systemic reactions, no safety concerns were identified.

TL;DR: In this article, the authors argue that rational actors make their organizations increasingly similar as they try to change them, and describe three isomorphic processes-coercive, mimetic, and normative.
Abstract: What makes organizations so similar? We contend that the engine of rationalization and bureaucratization has moved from the competitive marketplace to the state and the professions. Once a set of organizations emerges as a field, a paradox arises: rational actors make their organizations increasingly similar as they try to change them. We describe three isomorphic processes-coercive, mimetic, and normative—leading to this outcome. We then specify hypotheses about the impact of resource centralization and dependency, goal ambiguity and technical uncertainty, and professionalization and structuration on isomorphic change. Finally, we suggest implications for theories of organizations and social change.
