A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world

The Psychological Science Accelerator’s COVID-19 rapid-response dataset

In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments. Data were provided by 73,223 participants with varying completion rates. Participants completed the survey from 111 geopolitical regions in 44 unique languages/dialects. The anonymized dataset described here is provided in both raw and processed formats to facilitate re-use and further analyses. The dataset offers secondary analytic opportunities to explore coping, framing, and self-determination across a diverse, global sample obtained at the onset of the COVID-19 pandemic, which can be merged with other time-sampled or geographic data

An Evolutionary Approach to the Theory of Entrepreneurship

An economic model featuring entrepreneurial behaviour is built and tested using simulation techniques. The building blocks of our model are bounded-rational actors with specific sets of endowments: ""entrepreneurial spirit'', human capital, and venture capital. The entrepreneurial behaviour to found a firm is triggered by the individuals' endowments, their social network, and the evaluation of the economic situation. Bandwagon effects occur when high growth rates in emerging markets increase firm entries and firm entries in return increase growth rates until competition unfolds its selective power. The firm's survivability is determined by its founders' endowments and its competitiveness. Whether actors are right or wrong in evaluating their economic situation and their consequent decisions is proven ex post . Thus, there will be winners and losers in this economic system.

Nature value: the evolution of this concept Valor da natureza: a evolução desse conceito

More attention has been paid to environmental matters in recent years, mainly due to the current scenario of accentuated environmental degradation. The economic valuation of nature goods can contribute to the decision-making process in environment management, generating a more comprehensive informational base. This paper aims to present, in a historic perspective, the different concepts attributed to nature goods and were related to the current predominant perspectives of nature analyses. For this purpose, this paper presents the different concepts attributed to value since the pre-classical period, when nature were viewed as inert and passive providers of goods and services, this view legitimized nature's exploration without concern over the preservation and conservation of nature. The capacity of nature to absorb the impact of human action appears to be reaching its limit, considering the irreversibility, the irreproducibility and the possibility of collapse. The appropriate method for valuing natural resources is not known, but more important than the method is to respect and incorporate the particular characteristics of the nature goods into this process. These characteristics must be valuated in order to arrive at a more consistence approach to nature value and promote sustainability.<br>Nos últimos anos, mais atenção tem sido dada às questões ambientais, principalmente decorrente do atual cenário de acentuada degradação. A avaliação econômica dos recursos naturais pode contribuir com o processo de tomada de decisão na gestão ambiental, gerando uma importante base de informações. Neste artigo, buscou-se apresentar, em uma perspectiva histórica, os diferentes conceitos atribuídos ao valor dos recursos naturais e como eles se relacionam às perspectivas atuais de análise ambiental. Com essa finalidade, foram apresentados os conceitos atribuídos ao valor desde o período pré-clássico, quando a natureza era vista como fornecedora inerte e passiva de produtos e serviços, visão que legitimou sua exploração, sem considerações quanto à sua preservação e conservação. A capacidade da natureza de absorver o impacto das ações humanas parece estar chegando ao seu limite, em razão da irreversibilidade, irreprodutibilidade e possibilidade de colapso. Não se conhece um método totalmente apropriado para se avaliar os recursos naturais, porém, mais importante seria respeitar e incorporar as características particulares dos recursos naturais nesse processo. Essas características devem ser valoradas, a fim de se chegar a uma aproximação mais consistente do valor da natureza e promover a sustentabilidade
