Nomad Stories: Travelling in Times of Crisis

Cotocea, Ioana 14 January 2022 (has links)
Travel has been one of the sectors most severely affected by the COVID-19 pandemic. Countries have taken urgent and aggressive action to contain the spread of the virus by implementing measures such as travel bans, border closures, and lockdowns. This thesis theorizes the relationship between self-making, ethics, and travel at a time when movement has become restricted and morally questionable. It traces important ethical tensions generated by the pandemic and grounds them in different conceptualizations of uncertainty, risk, responsibility, and mobility. Through the examination of the historical and global forces that led to the globalization of movement, capital, bodies, and viruses, this work explores the new parameters of travel as produced by the pandemic and its ensuing restrictions. It argues that COVID-19 blurs the distinctions between local and global infrastructures, bodies, and forms of knowledge, rendering them increasingly difficult to maintain. By examining the unfolding of the global crisis and its effects on the practice of travel, this thesis unravels new and innovative patterns of consumption and envisions alternative futures for the tourism industry.

Payet, Eduardo, Perez, Joan, Sarria, Gustavo, Neciosup, Silvia, Berrospi, Francisco, Vilchez, Sheila, Dunstan, Jorge, Perez, Ronald, Vassallo, Mauricio, Salgado, Santiago, Caparachín, Nanto, Pinto, Joseph A., Holguin, Alexis 01 June 2021 (has links)
Background: Cancer patients are at higher risk of infection and severity of Coronavirus Disease-19 (COVID-19). Management of patients infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is challenging due to the scarce scientific information and treatment guidelines. In this work, we present our Institutional experience with our first 100 patients with oncological malignancies and COVID-19. Patients and methods: We conducted a cross-sectional study of the first 100 patients hospitalised at the Instituto Nacional de Enfermedades Neoplasicas (Lima, Peru) who were positive for SARS-CoV-2 by reverse transcriptase (RT)-PCR during the period 30 March to 20 June. Clinicopathological variables of the oncological disease as well as risk factors, management and outcomes to COVID-19 were evaluated. Results: The mean age was 43.5 years old (standard deviations: ±24.8) where 57% were male patients. In total, 44%, 37% and 19% were adult patients bearing solid tumours, adults with haematologic malignancies and paediatric patients, respectively. Hypertension was the most frequent comorbidity (23%) followed by chronic lung disease (10%). COVID-19-associated symptoms included cough (65%), fever (57%) and dyspnoea (56%). Twelve percent of patients were asymptomatic. Nosocomial infections were more frequent in paediatric patients (84.2%) than in adult patients (16.0%). Patients with uncontrolled oncological disease were most frequent (72%). Anaemia was present in 67% of patients, 68% had lymphopenia, 62% had ferritin value > 500 mcg/L, 85% had elevated lactate dehydrogenase (LDH), 83% D-dimer > 500 ng/mL and 80% C-Reactive Protein > 8 mg/L. The most common complication was acute respiratory failure (42%). Overall fatality rate was 39% where the main cause of mortality was acute respiratory distress syndrome (64.1%). Conclusion: Paediatric patients had better outcomes than adult populations, and a high number of asymptomatic carriers and nosocomial infection, early diagnosis are recommended. Considering oncological treatments 30 days before COVID-19 diagnosis, our data did not reveal an increased mortality. / Revisión por pares

Pandemias y salud pública: historias de cuarentenas y vacunaciones

31 October 2021 (has links)
"A lo largo de la historia de la República hemos confrontado numerosas pandemias producidas por distintas enfermedades como la viruela, la peste, el cólera, la influenza, el VIH-Sida y la covid-19. Las respuestas sociales a las pandemias estuvieron marcadas por instancias de pánico, discriminación, y búsqueda de culpables, aunque también por muestras de solidaridad hacia las poblaciones más vulnerables. Las respuestas estatales combinaron el aislamiento de las personas contagiadas, la imposición de cuarentenas, mejoras en las condiciones de la higiene pública y campañas de vacunación. Este libro trata los temas que las acompañan, tan relevantes para la actualidad." -- Cubierta posterior.

Derecho de los Desastres: COVID-19 / Tomo I: Perú

Facultad de Derecho (PUCP) 09 1900 (has links)
Terminando la segunda década del siglo XXI, el mundo se encuentra trágicamente zarandeado por una pandemia, algo que los ciudadanos comunes pensábamos que era cosa del pasado, que la arrogante especie dominante en la Tierra tenía las herramientas para combatir bacterias y virus, o para mantenerlas a raya en un corto período de tiempo, y que el status quo no sufriría cambios repentinos. Por lo que, con alegría o pesar, según el lado de la balanza en la que cada uno se encontraba, la vida transcurría bajo las reglas de una globalización que acentuaba las premisas del capitalismo, tras quedarse sin oponente político después de la caída del muro de Berlín.

The coronavirus disease 2019 (COVID-19) pandemic has caused a global health crisis. Consequently, many countries have adopted restrictive measures that caused a substantial change in society. Within this framework, it is reasonable to suppose that a sentiment of societal discontent, defined as generalized concern about the precarious state of society, has arisen. Literature shows that collectively experienced situations can motivate people to help each other. Since societal discontent is conceptualized as a collective phenomenon, we argue that it could influence intention to help others, particularly those who suffer from coronavirus. Thus, in the present study, we aimed (a) to explore the relationship between societal discontent and intention to help at the individual level and (b) to investigate a possible moderating effect of societal discontent at the country level on this relationship. To fulfil our purposes, we used data collected in 42 countries (N = 61,734) from the PsyCorona Survey, a cross-national longitudinal study. Results of multilevel analysis showed that, when societal discontent is experienced by the entire community, individuals dissatisfied with society are more prone to help others. Testing the model with longitudinal data (N = 3,817) confirmed our results. Implications for those findings are discussed in relation to crisis management.

Global research priorities for COVID-19 in maternal, reproductive and child health: Results of an international survey

Etti, Melanie, Alger, Jackeline, Salas, Sofia P., Saggers, Robin, Ramdin, Tanusha, Endler, Margit, Gemzell-Danielsson, Kristina, Alfven, Tobias, Ahmed, Yusuf, Callejas, Allison, Eskenazi, Deborah, Khalil, Asma, Le Doare, Kirsty 01 September 2021 (has links)
Background The World Health Organization's "Coordinated Global Research Roadmap: 2019 Novel Coronavirus"outlined the need for research that focuses on the impact of COVID-19 on pregnant women and children. More than one year after the first reported case significant knowledge gaps remain, highlighting the need for a coordinated approach. To address this need, the Maternal, Newborn and Child Health Working Group (MNCH WG) of the COVID- 19 Clinical Research Coalition conducted an international survey to identify global research priorities for COVID-19 in maternal, reproductive and child health. Method This project was undertaken using a modified Delphi method. An electronic questionnaire was disseminated to clinicians and researchers in three different languages (English, French and Spanish) via MNCH WG affiliated networks. Respondents were asked to select the five most urgent research priorities among a list of 17 identified by the MNCH WG. Analysis of questionnaire data was undertaken to identify key similarities and differences among respondents according to questionnaire language, location and specialty. Following elimination of the seven lowest ranking priorities, the questionnaire was recirculated to the original pool of respondents. Thematic analysis of final questionnaire data was undertaken by the MNCH WG from which four priority research themes emerged. Results Questionnaire 1 was completed by 225 respondents from 29 countries. Questionnaire 2 was returned by 49 respondents. The four priority research themes which emerged from the analysis were 1) access to healthcare during the COVID-19 pandemic, 2) the direct and 3) indirect effects of COVID-19 on pregnant and breastfeeding women and children and 4) the transmission of COVID-19 and protection from infection. Conclusion The results of these questionnaires indicated a high level of concordance among continents and specialties regarding priority research themes. This prioritized list of research uncertainties, developed to specifically highlight the most urgent clinical needs as perceived by healthcare professionals and researchers, could help funding organizations and researchers to answer the most pressing questions for clinicians and public health professionals during the pandemic. It is hoped that these identified priority research themes can help focus the discussion regarding the allocation of limited resources to enhance COVID-19 research in MNCH globally. / Revisión por pares

The (r)evolution of a miserable teacher - an autoethnography

De Wet, Chantelle January 2021 (has links)
When our family relocated from South Africa to Abu Dhabi in the United Arab Emirates (UAE) in 2015, I was not prepared for the inception of my personal evolution. Stepping into a classroom as a mathematics teacher, after nearly a decade of being a self-sustainable entrepreneur, forced me to evaluate my motives for becoming a teacher, and shifted my focus to progress and the development of my own pedagogy. Just as I was finding my feet in the British international schooling system in the UAE, the coronavirus disease of 2019 (Covid-19) resulted in a global pandemic and forced all schools to close and roll out distance learning education systems. In turn, this led to a revolution in the teaching profession as I knew it. Both of these contexts paved the way of the title of the thesis: The (r) evolution of a miserable teacher – an autoethnography Autoethnography challenges the canonical manner in which research is conducted, allowing the researcher to use her personal experience (auto) to understand the cultural experience (ethno) better and describe (graphy) the results in narrative form. This might be an oversimplified definition of a complex journey of self-discovery and contextual understanding, but holistically even a definition can evolve. The use of a postmodern perspective throughout the thesis ensured that the data were not limited to a singular paradigm but were rather a culmination of what was relevant at the time of the research. Through reflective and reflexive data collection and construction techniques, a progressive and innovative data graph was developed to visually enhance the (r)evolution of the data description, analysis and evaluation. Conceptual metaphor theory allowed Les Misérables to be the framework and foundation for the data to be constructed. This study contributes to the teachers' collective by combining traditional paradigms in a new, brave, evolutionary way. A personal evolution through resilience and agility became evident through reflective and reflexive data and literature. Evolution is never-ending, but by becoming aware of the effects of personal growth, the process is elevated to a sustainable focus in everyday life. The evolution did not falter when Covid- 19 forced the education sphere to momentarily pause at a possible revolutionary turning point. Distance education allowed politicians, school developers and owners, curriculum writers, principals, school boards and managers, teachers and parents to re-evaluate methodologies, curriculum content and inclusion policies, as well as the everyday implementation of policies and procedures. Literature proves that a revolution was necessary and Covid-19 made this possible by funnelling our expectations into experience. The revolution is far from complete but, similar to evolution, awareness leads to improved practice. / Thesis (PhD)--University of Pretoria, 2021. / Humanities Education / PhD / Unrestricted

Insights in Response to Statewide COVID-19 Sampling in Indiana

Shields, David William, Jr. 05 1900 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / During 2020, the Indiana State Department of Health conducted a longitudinal study of novel severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) virus, the cause of COVID-19 disease, to understand the number of past and current infections as well as the prevalence of disease in the State of Indiana by conducting a survey to participants as well as administering testing for exposure to SARS-COV-2. The study consisted of 3 waves of testing, each spread months apart, consisting of a random sample and a non-random sample. The non-random sample was used to ensure the sample population was representative of the state of Indiana and was used as stratum in the logistic regression model, allowing for the adjustment for nonresponse. These finding indicate that persons of non-White race and persons of Hispanic ethnicity had highest risk of exposure to the virus. Understanding the disparity in health in various racial and ethnic populations and addressing how different communities are impacted by the pandemic, as well as working with the community is paramount when attempting to mitigate a pandemic. In addition, understanding the data from the ambient pandemic when instituting measures to mitigate the spread of viruses is also extremely important for managing health emergencies such as the COVID-19 pandemic.

Classifying Previous Covid-19 Infection : Advanced Logistic Regression Approach / Klassifiering av tidigare Covid-19 infektion : Avancerad logistisk regressionsmetodik

Westerholm, Daniel January 2023 (has links)
The study aimed to developed a logistic model based on antibody proteins, vaccinations and demographic factors that predicts previous infection in Covid-19. The data set comprised of 2750 individuals from eldercare homes in Sweden, with four test dates executed between October of 2021 and August of 2022.  Exploratory data analysis revealed bimodal patterns in the antibodies against nucleocapsid protein within the non-infected group, raising suspicions of false negatives in the data. Due to the binary nature of the response and to be interpretable for further research, logistic regressions were used to model the relation between predictors and the logit of the response. Because of low performance scores and high probability for the presence of false negatives, K-means clustering algorithm was performed on the data. As a clustering variable, the logarithm of base 2 of the nucleocapsid protein was used, because of its theoretical relationship with previous infection in Covid-19.  Observations were reclassified using the clustering technique, and two new logistic models were fitted to the data. The final model contained polynomial terms to handle the non-linear relationship between the logit of the response and the predictors. We found a significant relationship between the logarithm of 2 of nucleocapsid protein and previous Covid-19 infection in the final model, with high prediction results. We reached an F1-score of 0.94, indicating a well-performing model.  Additionally, an algorithm was created to predict the days since infection, involving the change in nucleocapsid protein from one test date to the next, and a GAM model for fitting a smooth line to the data between nucleocapsid protein as response against the days since infection. Using this algorithm, we reached an absolute mean error between predicted results and actual days since infection of 23 days. This algorithm was later applied to observations reclassified in the clustering process.  In conclusion, the study successfully reclassified false negative observations with previous Covid-19 infection, and fitted a logistic model with high prediction score with F1-score of 0.94. Finally, an algorithm was created that estimated the days since infection with an absolute mean error of 23 days. / Syftet med studien var att utveckla en logistisk modell baserad på antikroppsproteiner, vaccinationer och demografiska faktorer som förutsäger tidigare infektion i Covid-19. Datamängden bestod av 2750 individer från äldreboenden i Sverige, med fyra testdatum utförda mellan oktober 2021 och augusti 2022.  Utforskande dataanalys visade på bimodala mönster i antikroppar mot nukleokapsidprotein inom den icke- infekterade gruppen, vilket gav upphov till misstankar om falskt negativa resultat i datamaterialet. På grund av svarets binära karaktär och för att vara tolkningsbara för vidare forskning användes logistiska regressioner för att modellera förhållandet mellan prediktorer och responsvariabeln. På grund av låga prediktionsresultat och hög sannolikhet av förekomsten av falskt negativa svar utfördes K-means-klusteralgoritmen på datat. Som klustervariabel användes logaritmen av bas 2 för nukleokapsidproteinet, på grund av dess teoretiska samband med tidigare infektion i Covid-19.  Observationerna omklassificerades med hjälp av klustertekniken, och två nya logistiska modeller anpassades till datat. Den slutliga modellen innehöll polynomiala termer för att hantera det icke-linjära förhållandet mellan responsens logit och prediktorerna. Vi fann ett signifikant samband mellan logaritmen av 2 av nuk- leokapsidprotein och tidigare Covid-19-infektion i den slutliga modellen, med ett högt prediktionsresultat. Vi nådde en F1-score på 0.94.  Dessutom skapades en algoritm som predicerade dagar sedan infektion med hjälp av förändringen i nukleokap- sidprotein från ett testdatum till nästa, och en GAM-modell för att anpassa ett glidande medelvärdeslinje till datat mellan nukleokapsidprotein som response mot dagarna sedan infektionen. Med hjälp av denna algoritm nåddes ett absolut medelfel på 23 dagar mellan prediktion och faktiskt tid sedan infektionen. Denna algoritm tillämpades senare på observationer som omklassificerats i klusterprocessen.  Sammanfattningsvis lyckades studien framgångsrikt omklassificera falskt negativa observationer med tidigare Covid-19-infektion och anpassade en logistisk modell med hög prediktionspoäng med en F1-score på 0.94. Slutligen skapades en algoritm som uppskattade dagarna sedan infektionen med ett absolut medelfel på 23 dagar.
