Grandiosity and vulnerability are distinct dimensions of narcissism that may exhibit differences regarding compliance with COVID-19 regulations and policies. Although both dimensions reflect entitlement and self-importance, motivational tendencies diverge. Narcissistic grandiosity reflects bold expressions consistent with approach motivation, whereas vulnerable narcissism reflects reactive expressions consistent with avoidance motivation. Therefore, the present cross-sectional investigation explored these relations between November 2020 and April 2021. Undergraduates (N = 487, Mage = 19.79, 87.1% women) completed online surveys that assessed grandiose and vulnerable narcissism, perceived severity of and susceptibility to COVID, attitudes and reactions toward COVID policies, as well as self-reported behavioral data including number of daily hours out in public, indoor bar/restaurant attendance, and whether they had ever received a positive COVID diagnosis. Consistent with theoretical distinctions between the two narcissistic dimensions, grandiosity generally predicted reduced behavioral compliance and extraverted tendencies that put them at risk for COVID exposure; however, both grandiosity and vulnerability predicted worse reactions and attitudes toward COVID-19 policies. 相似文献

In the pandemic era, social media has provided the public with a platform to make their voice heard. One of the most important public opinions online during a pandemic is blame. Blame can lead to stigma towards patients as well as potential patients and decrease social cooperation, which might impede prevention and control measures during epidemics. Thus, studying online blame during the early days of COVID-19 can facilitate the management and control of future pandemics. By analyzing 3791 posts from one of the most popular social media sites in China (Weibo) over the 10 days immediately after COVID-19 was declared to be a communicable disease, we found that there were four main agents blamed online: Individuals, corporations, institutions, and the media. Most of the blame targeted individual agents. We also found that there were regional-cultural differences in the detailed types of blamed individual agents, that is, between rice- and wheat-farming areas in China. After controlling influence of distance from the epicenter of Wuhan, there were still stable differences between regions: people in wheat areas had a higher probability of blaming agentic, harmful individuals, and people in rice areas had a higher probability of blaming individuals with low awareness of social norms for preventive health behavior. Findings have implications for preventing and predicting blame across cultures in future pandemics. 相似文献

Background
Early numeracy skills are associated with academic and life-long outcomes. Children from low-income backgrounds typically have poorer maths outcomes, and their learning can already be disadvantaged before they begin formal schooling. Understanding the relationship between the skills that support the acquisition of early maths skills could scaffold maths learning and improve life chances.Aims
The present study aimed to examine how the ability of children from different SES backgrounds to map between symbolic (Arabic numerals) and non-symbolic (dot arrays) at two difficulty ratios related to their math performance.Sample
Participants were 398 children in their first year of formal schooling (Mean age = 60 months), and 75% were from low SES backgrounds.Method
The children completed symbolic to non-symbolic and non-symbolic to symbolic mapping tasks at two difficulty ratios (1:2; 2:3) plus standardized maths tasks.Results
The results showed that all the children performed better for symbolic to non-symbolic mapping and when the ratio was 1:2. Mapping task performance was significantly related to maths task achievement, but low-SES children showed significantly lower performance on all tasks.Conclusion
The results suggest that mapping tasks could be a useful way to identify children at risk of low maths attainment. 相似文献835.

Factor analysis by generalized least squares 总被引:1,自引:0,他引:1
Aitken's generalized least squares (GLS) principle, with the inverse of the observed variance-covariance matrix as a weight matrix, is applied to estimate the factor analysis model in the exploratory (unrestricted) case. It is shown that the GLS estimates are seale free and asymptotically efficient. The estimates are computed by a rapidly converging Newton-Raphson procedure. A new technique is used to deal with Heywood cases effectively.The work on this project was done when the first author was Research Statistician at Educational Testing Service, Princeton, N. J. The second author was in part supported by a grant from the Research Committee of the University of Wisconsin Graduate School. The authors wish to thank Michael Browne for many helpful comments and Marielle van Thillo for valuable assistance in the numerical computations. 相似文献
