Atividade externa e coleta de recursos em ninhos naturais por campeiras da abelha canudo Scaptotrigona bipunctata (Hymenoptera, Apidae, Meliponini).
O objetivo desse trabalho foi investigar a atividade externa e a coleta de recursos por campeiras da abelha canudo (Scaptotrigona bipunctata), a partir de dois ninhos naturais. O estudo foi conduzido no Setor de Apicultura do Departamento de Zootecnia, da Universidade Federal do Ceará, durante os meses de novembro de 2006 à março de 2007, uma vez por semana, com intervalos regulares de sete dias. A entrada da colônia foi bloqueada com uma pequena esponja e as operárias coletadas com o auxílio de sugadores de insetos, e analisadas se carregavam pólen, resina ou nenhum recurso visível, provavelmente néctar ou água no papo. Os resultados mostraram que a coleta de pólen e néctar ou água se concentrou cedo da manhã, enquanto que a coleta de resina ocorreu igualmente ao longo do dia. Conclui-se que as abelhas canudo concentram suas atividades pela manhã, e evitam forragear nas horas mais quentes do dia, provavelmente coletando água nestes horários para reduzir a temperatura interna do ninho

Stress and worry in the 2020 coronavirus pandemic: relationships to trust and compliance with preventive measures across 48 countries in the COVIDiSTRESS global survey.
The COVIDiSTRESS global survey collects data on early human responses to the 2020 COVID-19 pandemic from 173 429 respondents in 48 countries. The open science study was co-designed by an international consortium of researchers to investigate how psychological responses differ across countries and cultures, and how this has impacted behaviour, coping and trust in government efforts to slow the spread of the virus. Starting in March 2020, COVIDiSTRESS leveraged the convenience of unpaid online recruitment to generate public data. The objective of the present analysis is to understand relationships between psychological responses in the early months of global coronavirus restrictions and help understand how different government measures succeed or fail in changing public behaviour. There were variations between and within countries. Although Western Europeans registered as more concerned over COVID-19, more stressed, and having slightly more trust in the governments' efforts, there was no clear geographical pattern in compliance with behavioural measures. Detailed plots illustrating between-countries differences are provided. Using both traditional and Bayesian analyses, we found that individuals who worried about getting sick worked harder to protect themselves and others. However, concern about the coronavirus itself did not account for all of the variances in experienced stress during the early months of COVID-19 restrictions. More alarmingly, such stress was associated with less compliance. Further, those most concerned over the coronavirus trusted in government measures primarily where policies were strict. While concern over a disease is a source of mental distress, other factors including strictness of protective measures, social support and personal lockdown conditions must also be taken into consideration to fully appreciate the psychological impact of COVID-19 and to understand why some people fail to follow behavioural guidelines intended to protect themselves and others from infection. The Stage 1 manuscript associated with this submission received in-principle acceptance (IPA) on 18 May 2020. Following IPA, the accepted Stage 1 version of the manuscript was preregistered on the Open Science Framework at https://osf.io/g2t3b. This preregistration was performed prior to data analysis
COVIDiSTRESS diverse dataset on psychological and behavioural outcomes one year into the COVID-19 pandemic
During the onset of the COVID-19 pandemic, the COVIDiSTRESS Consortium launched an open-access global survey to understand and improve individuals’ experiences related to the crisis. A year later, we extended this line of research by launching a new survey to address the dynamic landscape of the pandemic. This survey was released with the goal of addressing diversity, equity, and inclusion by working with over 150 researchers across the globe who collected data in 48 languages and dialects across 137 countries. The resulting cleaned dataset described here includes 15,740 of over 20,000 responses. The dataset allows cross-cultural study of psychological wellbeing and behaviours a year into the pandemic. It includes measures of stress, resilience, vaccine attitudes, trust in government and scientists, compliance, and information acquisition and misperceptions regarding COVID-19. Open-access raw and cleaned datasets with computed scores are available. Just as our initial COVIDiSTRESS dataset has facilitated government policy decisions regarding health crises, this dataset can be used by researchers and policy makers to inform research, decisions, and policy. © 2022, The Author(s).U.S. Department of Education, ED: P031S190304; Texas A and M International University, TAMIU; National Research University Higher School of Economics, ВШЭThe COVIDiSTRESS Consortium would like to acknowledge the contributions of friends and collaborators in translating and sharing the COVIDiSTRESS survey, as well as the study participants.

Correlatos valorativos de atitudes frente à tatuagem Value correlates of attitudes toward tattoo
Este estudo objetivou conhecer em que medida os valores explicam as atitudes frente à tatuagem e estas, por sua vez, predizem a intenção de tatuar-se. Participaram 263 estudantes universitários de João Pessoa, com idade média de 20,7 anos, a maioria homem (54,7%) e solteira (91%). Estes responderam a Escala de Atitudes frente à Tatuagem, o Questionário dos Valores Básicos e perguntas demográficas (idade, sexo, religiosidade). Os resultados indicaram atitudes dos participantes mais negativas frente à tatuagem, sobretudo aqueles de ciências exatas e naturais. Comprovou-se a adequação de um modelo triádico, onde os valores predisseram as atitudes frente à tatuagem e, estas, a intenção de tatuar-se. Especificamente, a subfunção normativa promoveu atitudes negativas frente à tatuagem, enquanto a subfunção experimentação favoreceu aquelas mais positivas. Conclui-se que as atitudes frente à tatuagem têm base valorativa, explicando a intenção de tatuar-se. Sugeriram-se pesquisas futuras que contribuam para explicar as atitudes frente à tatuagem.<br>This study investigated the extent to which values explain the attitudes towards tattoos and these, in turn, predict the intention of tattooing. Participants were 263 undergraduate students from João Pessoa (Brazil), with mean age of 20.7 years, mostly men (54.7%) and unmarried (91%). They answered the Attitudes toward Tattoo Scale, the Basic Values Survey and demographic questions (age, gender, and religiosity). Results indicated that the participants' attitudes toward tattooing were predominantly negatives, especially among students of natural and exact sciences. The adequacy of a triadic model was proved, where human values predicted attitudes toward tattooing and these, the intention of getting tattooed. Specifically, the value subfunction normative promoted negative attitudes toward tattooing, while the subfunction excitement favored more positive attitudes. In conclusion, attitudes toward tattooing have a value basis, accounting for people intention of getting tattooed. Future research is suggested to contribute on the explanation of attitudes toward tattooing
