Minds of Monsters
Four studies investigate a fear of imbalanced minds hypothesis that threatening agents perceived to be relatively mismatched in capacities for cognition (e.g., self-control and reasoning) and emotion (e.g., sensations and emotions) will be rated as scarier and more dangerous by observers. In ratings of fictional monsters (e.g., zombies and vampires), agents seen as more imbalanced between capacities for cognition and emotion (high cognition–low e…
Variations of Rotating Savings and Credit Associations for Community Development
Informal financial cooperation strategies have emerged as a solution to improve the resilience of low-income communities, being one of the most popular ones the rotating savings and credit associations (ROSCAs). In this article, using computational tools and dynamical systems modeling, we study the performance of two variations of ROSCAs that can potentially increase the resilience of communities. First, we propose a strategy that saves a percent…
Informality, economic complexity, and internalization of rules
This research aimed to find out the relationship between informality and the internalization of the rules of behavior required for complexity in the economic system, as better knowledge is required for formalization policy to have a greater impact. We use the economic complexity index (ECI) for 2018 at the regional level in Colombia, which combines the country's productive structure with the amount of knowledge and know-how embodied in the goods …
Sensitivity analysis of rapid antigen tests for the Omicron Sars-CoV-2 variant detection from nasopharyngeal swab samples collected in Santiago of Chile
The COVID-19 pandemic continues to be a concern and keeps global health authorities on alert. The RT-PCR technique has been the gold-standard assay for detecting the SARS-CoV-2 virus. However, rapid antigen tests (RATs) have been widely used to increase the number of tests faster and more efficiently in the population. Nevertheless, the appearance of new viral variants, with genomic mutations associated with greater contagiousness and immune evas…
Description of Symptoms Caused by the Infection of the Sars-CoV-2 B.1.621 (Mu) Variant in Patients With Complete CoronaVac Vaccination Scheme
Vaccine administration is one of the most efficient ways to control the current coronavirus disease 2019 (COVID-19) pandemic. However, the appearance of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants can avoid the immunity generated by vaccines. Thus, in patients with a complete vaccine schedule, the infection by SARS-CoV-2 may cause severe, mild, and asymptomatic manifestations of the disease. In this case report, we descr…
The importance of being unearnest
cooperation in a society. The studies illuminate the role Opportunists play in producing these backfire effects. In addition to highlighting other features shaping culture (e.g., risk and reward in the environment, "founder effects" requiring a critical mass of certain strategies at a culture's initial stage), the studies help illustrate how Opportunists create aspects of culture that otherwise seem paradoxical, are dismissed as "error," or produ…
Donation Networks in Underprivileged Communities
Individuals who have very low income and belong to an underprivileged community have a challenging task when managing their financial life, typically due to negative unpredictable events and lack of health and financial services. Cooperation strategies based on savings and credits are becoming a very important option for these communities to address such challenges and to have some level of financial stability. Since designing new cooperation str…
Rationally Irrational?
A commitment to honor is a commitment to irrationality—at least in the short-run—because it involves defending one’s honor, regardless of stakes or cost. Yet, circumstances giving rise to honor cultures—lawless environments, portable (easy-to-steal) wealth—create milieus where people must appear tough to deter predators. Thus, what seems irrational in the short-run may be rational in the long-run. This chapter describes three agent-based models e…
The role of social networks in the inclusion of small-scale producers in agri-food developing clusters
People in more racially diverse neighborhoods are more prosocial
Five studies tested the hypothesis that people living in more diverse neighborhoods would have more inclusive identities, and would thus be more prosocial. Study 1 found that people residing in more racially diverse metropolitan areas were more likely to tweet prosocial concepts in their everyday lives. Study 2 found that following the 2013 Boston Marathon bombings, people in more racially diverse neighborhoods were more likely to spontaneously o…
Happy Tweets
We analyze data from nearly 2 million text messages (tweets) across over 16,000 users on Twitter to examine differences between Christians and atheists in natural language. Analyses reveal that Christians use more positive emotion words and less negative emotion words than atheists. Moreover, two independent paths predict differences in expressions of happiness: frequency of words related to an intuitive (vs. analytic) thinking style and frequenc…
Entrepreneurship, institutional variety and economic development
The contribution of entrepreneurship to economic growth varies across countries at different stages of economic development. The type of entrepreneurship also varies as countries develop: the ratio of necessity-based entrepreneurial firms (new entrepreneurial ventures born to escape unemployment) relative to opportunity-based entrepreneurial firms (new entrepreneurial ventures driven by business opportunities) changes as economies grow. Governmen…
Institutionalizing climate change adaptation at municipal and state level in Chetumal and Quintana Roo, Mexico
This paper is a report on one of three related case studies in Latin America and shows the progress in the city of Chetumal, and the larger state of which it is the capital (Quintana Roo), in disaster response, especially with regard to cyclones. It also shows the progress in land use and ecological planning through the development of certain tools, which have changed the approach from one of prohibiting action to suggesting alternatives. Rather …
Polarized Attitudes Toward the Ground Zero Mosque are Reduced by High-Level Construal
On the basis of construal level theory (Trope & Liberman, 2010), we hypothesized that political polarization on controversial issues may be reduced by increasing abstract mental construal. Using the issue of the “Ground Zero Mosque” and political polarization on it as an example, we first established that liberals and conservatives hold opposing attitudes toward building a mosque near Ground Zero (Study 1). Polarized attitudes were significantly …
