Individual low-carbon behaviors and influencing factors: Insights from a behavior survey study in China.

Climate change is a major global concern. Greenhouse gas emissions that cause global climate change are directly or indirectly affected by human activities. Individual low-carbon behaviors are crucial in reducing CO2 emissions and improving environmental and ecological health. To effectively promote individual low-carbon behavior, this study designed a questionnaire on the factors influencing individual low-carbon intentions and behavior based on theoretical models of environmental behavior. A total of 2430 valid questionnaires were collected in China. This study focuses on analyzing the impact of demographic characteristics, internal and external factors on individual low-carbon behaviors and their interrelationships. The research shows correlations between internal and external factors in determining low-carbon intention or behaviors. Internal factors-related low-carbon behavior is not closely linked with demographic variables, whereas the external factors-related low-carbon behavior vary significantly by age, residence, education, marital status, occupation, and income. The findings have important implications for designing effective policies to promote low-carbon behaviors, such as creating a more favorable external environment and increasing the use of policy tools for reducing CO2 emission.

Attitudes and personal beliefs about the COVID-19 vaccine among people with COVID-19: a mixed-methods analysis.

BACKGROUND: Little research is available regarding vaccination attitudes among those recently diagnosed with COVID-19. This is important to investigate, particularly among those experiencing mild-to-moderate illness, given the ongoing need to improve uptake of both initial vaccine series and booster doses, and the divergent ways such an experience could impact attitudes. METHODS: From September 3 - November 12, 2021, all patients enrolled in Baylor Scott & White's "COVID-19 Digital Care Journey for Home Monitoring" were invited to participate in an online survey that included questions about vaccination status and attitudes/opinions regarding COVID-19 and the COVID-19 vaccines. Following an item asking about accordance of COVID-19 vaccination with religious/personal beliefs, participants were asked to describe those beliefs and how they relate to taking/not taking the vaccine. RESULTS: Of 8,075 patients age ≥ 18 years diagnosed with COVID-19 and invited to join the survey during the study period, 3242 (40.2%) were fully vaccinated. In contrast, among the 149 who completed the questionnaire, 95(63.8%) reported full vaccination. Responses differed significantly between vaccination groups. The vaccinated group strongly agreed that COVID-19 is a major public health problem, the vaccines are safe and effective, and their decision to vaccinate included considering community benefit. The unvaccinated group responded neutrally to most questions addressing safety and public health aspects of the vaccine, while strongly disagreeing with statements regarding vaccine effectiveness and other preventative public health measures. The vaccinated group strongly agreed that taking the vaccine accorded with their religious/personal beliefs, while the unvaccinated group was neutral. In qualitative analysis of the free text responses "risk perception/calculation" and "no impact" of religious/personal beliefs on vaccination decisions were frequent themes/subthemes in both groups, but beliefs related to the "greater good" were a strong driver among the vaccinated, while statements emphasizing "individual choice" were a third frequent theme for the unvaccinated. CONCLUSION: Our results show that two of the three factors that drive vaccine hesitancy (complacency, and lack of confidence in the vaccines) are present among unvaccinated adults recently diagnosed with COVID-19. They also show that beliefs emphasizing the importance of the greater good promote public health participation.

How you named your child: understanding the relationship between individual decision making and collective outcomes.

We examine the interdependence between individual and group behavior surrounding a somewhat arbitrary, real-world decision: selecting a name for one's child. Using a historical database of the names given to children over the last century in the United States, we find that naming choices are influenced by both the frequency of a name in the general population, and by its ''momentum'' in the recent past in the sense that names which are growing in popularity are preferentially chosen. This bias toward rising names is a recent phenomena: In the early part of the 20th century, increasing popularity of a name from one time period to the next correlated with a decrease in future popularity. However, more recently this trend has reversed. We evaluate a number of formal models that detail how individual decision-making strategies, played out in a large population of interacting agents, can explain these empirical observations. We argue that cognitive capacities for change detection, the encoding of frequency in memory, and biases toward novel or incongruous stimuli may interact with the behavior of other decision makers to determine the distribution and dynamics of cultural tokens such as names.
