BACKGROUND Emergence and evolution of online discourse on Twitter concerning the COVID-19 pandemic are crucial for public health and public relation officials to understand the prevailing perception of the disease and its impact. Despite the global scale of this pandemic, comparison and contrast of topics, sentiment and emotions of tweets among countries are limited. Further, most previous studies covered a short timeframe due to the recency of the event and the large volume of tweets. OBJECTIVE The purposes of this research were to 1) identify the multiplicity of public discourse during the COVID-19 pandemic and how they evolved, (2) compare and contrast sentiment levels and (3) compare emotions about countries over time. METHODS The research scope covered ten countries in Southeast Asia (SEA). We analysed 115,553 tweets that mentioned these countries from 22 January 2020 to 31 July 2021 using a topic modelling algorithm (latent Dirichlet allocation — LDA), VADER and NRC sentiment analyses. RESULTS We identified the emergence and evolution of twelve topics that were further grouped into early, parallel and late discourse. Each country had distinct topics and trends depending on differing internal and external factors. Sentiment improved with positive tweets of hope and fell when negative narratives predominated as a result of new waves of COVID-19. Four emotions that are prevalent during the pandemic were trust, fear, anticipation and sadness CONCLUSIONS This research detected the many divergent phases and faces of the pandemic on Twitter, the intertwined discourse of a double disaster and the role played by an infodemic on place brand association. Our results will assist public health and public relations officials to better understand how public discourse emerged and evolved with the COVID-19 pandemic.

Topic modelling is often described as a text-mining tool for conducting a study of hidden semantic structures of a text or a text corpus by extracting topics from a document or a collection of documents. Yet, instead of one singular method, there are various tools for topic modelling that can be utilised for historical research. Dynamic topic models, for example, are often constructed temporally year by year, which makes it possible to track and analyse the ways in which topics change over time. This chapter provides a case example on topic modelling historical primary sources. The chapter uses two tools to carry out topic modelling, MALLET and Dynamic Topic Model (DTM), in one dataset, containing texts from the early 19th-century German-language press which have been subjected to optical character recognition (OCR). All of these texts were discussing humanism, which was a newly emerging concept before mid-century, gaining various meanings in the public discourse before, during and after the 1848–1849 revolutions. Yet, these multiple themes and early interpretations of humanism in the press have been previously under-studied. By analysing the evolution of the topics between 1829 and 1850, this chapter aims to shed light on the change of the discourse surrounding humanism in the early 19th-century German-speaking Europe.

The emergence in China of 2019 of severe acute respiratory syndrome coronavirus2 (SARS-CoV-2) previously provisionally names 2019-nCoV disease (COVID19) caused major global outbreak and is a major public health problem. On 30 January 2020, the WHO declared COVID19 to be the sixth international public health emergency. This present pandemic has engrossed the globe with a high rate of mortality. As a front line practitioner, physiotherapists are expected to be getting in direct contact with patients infected with the virus. That’s why it is necessary for understanding the many aspects of their role in the identification, contains, reduces and treats the symptoms of this disease. The main presentation is the involvement of respiratory system with symptoms like fever, cough, sore throat, sneezing and characteristics of pneumonia leads to ARDS(Acute respiratory distress syndrome) also land up in multiorgan dysfunction syndrome. This text describes and suggests physiotherapy management of acute COVID-19 patients. It also includes recommendations and guidelines for physiotherapy planning and management. It also covers the guidelines regarding personal care and equipment used for treatment which can be used in the treatment of acute adult patients with suspected or confirmed COVID-19.

As recently as one year ago, the European Union was seemingly on a direct path toward its avowed goal of "ever closer union." In numerous publications, EU authorities asserted that they had the confidence of European peoples desirous only of further integration. In the wake of the failed referenda for a European Constitution, however, enthusiasts of European Union can no longer be certain that their enterprise will succeed. The European Union, once strong and united, seems now an entity teetering on the edge of collapse. The reasons for such a dramatic shift are, of course, wide-ranging. Yet I would suggest that a great part of the general European disillusionment with European Union has come about as a result of the actions of the Europeanists themselves. Over the last decades, European officials have exhibited a frightfully high incidence of revisionism in their literature. This practice, I argue, has caused many Europeans to question the integrity of the project of European Union. For my presentation, I intend to undertake a close study of a selection of documents published by the European Communities. In this endeavour, I will compare and contrast the messages imparted in different editions of these works and consider the semiotic significance of the textual and non-textual language appearing therein. In this manner, I hope to achieve two aims. First, I mean to add a corrective element to a literature that, guided by a teleological interpretation of integration, endows integration with”logic" to be found only in hindsight. Second, I intend to examine the many meanings that the EU has had over its history and assess how closely policy has adhered to the ideological goals of prominent Europeanists. In sum, I hope to shed light on the fundamental disconnect between advocates of Europe and the "man on the street" and help establish a dialogue which may contribute to resolving the current impasse within the European Union.

This chapter highlights just a sample of the many rich areas for dissemination and implementation research that will assist us in shortening the gap between discovery and practice, thus beginning to realize the benefits of research for patients, families, and communities. Greater emphasis on implementation in challenging settings, including lower and middle-income countries and underresourced communities in higher income countries will add to the lessons we must learn to fully reap the benefit of our advances in dissemination and implementation research methods. Moreover, collaboration and multidisciplinary approaches to dissemination and implementation research will help to make efforts more consistent and more effective moving forward. Thus, we will be better able to identify knowledge gaps that need to be addressed in future dissemination and implementation research, ultimately informing the practice and policies of clinical care and public health services.

Climate And Health

Abstract Background Despite scientific evidence that climate change has profound and far reaching implications for public health, translating this knowledge in a manner that supports citizen engagement, applied decision-making, and behavioural change can be challenging. This is especially true for complex vector-borne zoonotic diseases such as Lyme disease, a tick-borne disease which is increasing in range and impact across Canada and internationally in large part due to climate change. This exploratory research aims to better understand public risk perceptions of climate change and Lyme disease in order to increase engagement and motivate behavioural change. Methods A focus group study involving 61 participants was conducted in three communities in the Canadian Prairie province of Manitoba in 2019. Focus groups were segmented by urban, rural, and urban-rural geographies, and between participants with high and low levels of self-reported concern regarding climate change. Results Findings indicate a broad range of knowledge and risk perceptions on both climate change and Lyme disease, which seem to reflect the controversy and complexity of both issues in the larger public discourse. Participants in high climate concern groups were found to have greater climate change knowledge, higher perception of risk, and less skepticism than those in low concern groups. Participants outside of the urban centre were found to have more familiarity with ticks, Lyme disease, and preventative behaviours, identifying differential sources of resilience and vulnerability. Risk perceptions of climate change and Lyme disease were found to vary independently rather than correlate, meaning that high climate change risk perception did not necessarily indicate high Lyme disease risk perception and vice versa. Conclusions This research contributes to the growing literature framing climate change as a public health issue, and suggests that in certain cases climate and health messages might be framed in a way that strategically decouples the issue when addressing climate skeptical audiences. A model showing the potential relationship between Lyme disease and climate change perceptions is proposed, and implications for engagement on climate change health impacts are discussed.

AbstractThe datafication and digitalization of health and medicine has engendered a proliferation of new collaborations between public health institutions and data corporations like Google, Apple, Microsoft and Amazon. Critical perspectives on these new partnerships tend to frame them as an instance of market transgressions by tech giants into the sphere of health and medicine, in line with a “hostile worlds” doctrine that upholds that the borders between market and non-market spheres should be carefully policed. This article seeks to outline the limitations of this common framing for critically understanding the phenomenon of the Googlization of health. In particular, the mobilization of a diversity of non-market value statements in the justification work carried out by actors involved in the Googlization of health indicates the co-presence of additional worlds or spheres in this context, which are not captured by the market vs. non-market dichotomy. It then advances an alternative framework, based on a multiple-sphere ontology that draws on Boltanski and Thevenot’s orders of worth and Michael Walzer’s theory of justice, which I call a normative pragmatics of justice. This framework addresses both the normative deficit in Boltanski and Thevenot’s work and provides an important emphasis on the empirical workings of justice. Finally, I discuss why this framework is better equipped to identify and to address the many risks raised by the Googlization of health and possibly other dimensions of the digitalization and datafication of society.

The Future

On the 25 March 2017, leaders of the EU27 and European Union (EU) institutions ratified the Rome Declaration. They committed to invite citizens to discuss Europe’s future and to provide recommendations that would facilitate their decision-makers in shaping their national positions on Europe. In response, citizens’ dialogues on the future of Europe were instituted across the Union to facilitate public participation in shaping Europe. This paper explores Ireland’s set of dialogues which took place during 2018. Although event organisers in Ireland applied a relatively atypical and more systematic and participatory approach to their dialogues, evidence suggests that Irelands’ dialogues were reminiscent of a public relations exercise which showcased the country’s commitment to incorporating citizens into the debate on Europe while avoiding a deliberative design which could have strengthened the quality of public discourse and the quality of public recommendations. Due to an absence of elite political will for a deliberative process, as well as structural weaknesses in design, participants’ recommendations lacked any clear and prescriptive direction which could shape Ireland’s national position on the future of Europe in any constructive or meaningful way.

Emerging Viral Diseases

AbstractEmerging infectious diseases (EIDs) are an increasing threat to public health on a global scale. In recent times, the most prominent outbreaks have constituted RNA viruses, spreading via droplets (COVID-19 and Influenza A H1N1), directly between humans (Ebola and Marburg), via arthropod vectors (Dengue, Zika, West Nile, Chikungunya, Crimean Congo) and zoonotically (Lassa fever, Nipah, Rift Valley fever, Hantaviruses). However, specific approved antiviral therapies and vaccine availability are scarce, and public health measures remain critical. Patients can present with a spectrum of ocular manifestations. Emerging infectious diseases should therefore be considered in the differential diagnosis of ocular inflammatory conditions in patients inhabiting or returning from endemic territories, and more general vigilance is advisable in the context of a global pandemic. Eye specialists are in a position to facilitate swift diagnosis, improve clinical outcomes, and contribute to wider public health efforts during outbreaks. This article reviews those emerging viral diseases associated with reports of ocular manifestations and summarizes details pertinent to practicing eye specialists.
