Effectiveness of the CoronaVac® vaccine in a region of the Colombian Amazon, was herd immunity achieved?

Introduction Currently, more than 4.5 billion doses of SARS-CoV-2 vaccines have been applied worldwide. However, some developing countries are still a long way from achieving herd immunity through vaccination. In some territories, such as the Colombian Amazon, mass immunization strategies have been implemented with the CoronaVac® vaccine. Due to its proximity to Brazil, where one of the variants of interest of SARS-CoV-2 circulates. Objective To determine the effectiveness of the CoronaVac® vaccine in a population of the Colombian Amazon. Methods Between February 24, 2021, and August 10, 2021, a descriptive observational study was carried out in which a population of individuals over 18 years of age immunized with two doses of the CoronaVac® vaccine was evaluated. The study site was in the municipality of Mitú, Vaupés, in southeastern Colombia, a region located in the Amazon bordering Brazil. Results. 99% of the urban population of the Mitú municipality were vaccinated with CoronaVac®. To date, 5.7% of vaccinated individuals have become ill, and only 0.1% of these require hospitalization. One death was attributable to COVID-19 has been reported among vaccinated individuals, and the vaccine has shown 94.3% effectiveness against mild disease and 99.9% against severe infection. Conclusions The herd immunity achieved through mass vaccination in this population has made it possible to reduce the rate of complicated cases and mortality from COVID-19 in this region of the Colombian Amazon. Highlights CoronaVac® has shown 94.3% effectiveness against mild disease and 99.9% against severe infection in this indigenous population. CoronaVac® reduces the mortality rate from 2.2% in 2020 to 0.22% in 2021. The herd immunity was achieved through mass vaccination in this region of the Colombian Amazon.

An Accessible City is a Healthy and People-Centred Smart City

Accessibility for all is an inspiring issue for future urban agendas. In European cities, the ageing of urban population and the growth of social and economic disparities call for interdisciplinary reflection and practice on the relations between well-being and inclusion and the organization and upgrading of public facilities. The challenge is to ensure the usability of urban spaces to the largest extent of persons, according to their different capabilities. Based on research developed at the University of Trieste (Italy), and taking the region Friuli Venezia Giulia as its main study context, the article questions a variety of recent urban tools and policies in order to show their level of innovation and the obstacles that still oppose their more effective integration. The aim is to highlight possible fields for public action and the need to rethink planning instruments and technical skills in the frame of a user experience and smart design approach.

COVID-19 vaccination in rural India: a battle to be won!

As of 22nd July 2021, 13.3% of world’s population are fully vaccinated and 26.8% of world’s population have received at least one dose of COVID-19 vaccine. COVID-19 vaccination drive was launched in India on 16th January 2021 with two government approved vaccines Covishield® and Covaxin®. About 65.53% of India’s population resides in rural areas. As vaccination is progressing, a gap (of number of vaccines administered) between urban and rural vaccination centers is clearly becoming evident. By mid-May, 30.3% of India’s urban population had received at least one dose of the vaccine compared to 19.2% in semi-urban areas, 15.1% in semi-rural areas and just 12.7% in rural areas. Vaccine roll out in rural areas is adversely affected probably because of unequal access in rural area, vaccine hesitancy due to misinformation and myths being circulated through social media and low educational status of rural population as compared to the urban peers. A successful COVID-19 vaccination drive depends on maximum possible coverage. Through this manuscript we aim to draw attention to objective and feasible strategies in order to bridge the existing urban-rural vaccination gap.

Examining country development indicators and e-waste under the moderating effect of country development levels and e-waste policy

PurposeThe purpose of this paper is to investigate if country development indicators, i.e. gross domestic product per capita (GDPPC), literacy rate, internet penetration and urban population, influence the generation of e-waste on a global level. The moderation effect due to differences between countries in terms of absence or presence of e-waste policy and level of development is also checked.Design/methodology/approachThis is an archival study that builds upon data from United Nations (UN), World Bank and Global E-waste Statistics Partnership. The authors did a path analysis comprising mediation and multigroup analyses to decipher the proposed rese arch model containing data from 172 countries.FindingsThe results indicate that GDPPC, literacy rate, internet penetration and urban population do not directly influence the generation of e-waste. However, higher internet penetration in developing countries leads to higher e-waste, while higher literacy rates in developed countries suppress e-waste generation. When it comes to e-waste policy, a higher urban population without a regulatory legal framework boosts higher e-waste. The authors observed that higher internet penetration leads to higher e-waste in the presence of e-waste policy as well.Originality/valueThis is the first study to include economic well-being indicators in elaborating e-waste generation, on a global scale. No previous study has observed differences between countries nested in e-waste policy and level of development.

The Charro as a Humorous Rural Stereotype in Mexico in the 1920s

At the beginning of the 20th century, the charro, a traditional figure from the rural world, emerged on the Mexican cultural scene as a relevant stereotype. In the following years, the charro transformed into a national personification of Mexico, especially once it became a key figure of Mexican cinema and mariachi music. Notwithstanding this fact, its trajectory was more convoluted than it seems, and different versions of the character coexisted at least until the 1920s. Whereas the charro was usually represented as an attractive and seductive man, there was also a comic version, portrayed as an overweight or unkempt man with a provincial mentality. The characters played by the comic performer Leopoldo Beristáin and the protagonists of Sunday comic strips, such as Don Catarino and Mamerto Albondiguilla, were some examples of the latter. While the positive interpretation of the charro ended up prevailing as the main iteration of the character, the comic depictions of this stereotype show the rejection and contempt that the urban population felt for a rural world that had invaded the Mexican capital as a result of the revolution—a world perceived as provincial, backward, and laughable, an idea that would dominate foreign and national imageries of Mexico.

Городские агломерации: проблемы и тенденции развития

The subject of this research was the modern urban agglomerations and its aim was to find out the main tendencies of their development by way of the analyses of problems faced by urban agglomerations and their management mechanisms. The main method of the conducted research was the comparative legal method, as the study is based on comparing the experience of different countries in the sphere of urban governance. The author used sociological, systemic and structural-functional approaches as well. The author believes that the problems faced by urban agglomerations are caused by the activities of different administrative bodies at their territory, the lack of proper coordination in the face of pretty acute rivalry between them. The mentioned problems are also exacerbated by modern migration processes. The number of “native” inhabitants is being decreased in many cities, the middle class is largely moving to suburbs while poor people are moving to urban centers, the urban population is getting older. The article also contains the analyses of different attitudes towards organization of administrative structures at the territory of the modern agglomeration. Proponents of only one strong jurisdiction, functioning within the agglomeration and taking decisions obligatory for the whole area, were called “consolidationists. “Polycentrists” believe that the more various jurisdictions function within the agglomeration the better, because centralized and hierarchical administrative model is outdated and ineffective.
