Marital Satisfaction and Maternal Emotional Expressiveness: Links with Children's Sibling Relationships

Associations between marital quality, maternal emotional expressiveness and children's sibling relationships were examined in a sample of 64 seven-year-olds and their mothers. Mothers reported on the quality of their marital relationships, and children rated the quality of their sibling relationships. Mothers and children provided data on maternal emotional expressiveness. Results indicated that marital dissatisfaction was associated with hostile and rivalrous sibling relationships and with maternal negative emotional expressiveness. Mothers' negative emotional expressiveness was correlated with hostile and rivalrous sibling relationships, and maternal positive emotional expressiveness was associated with affectionate sibling relationships. Maternal emotional expressiveness mediated the links between the marital relationship and sibling hostility and rivalry.     

Harnessing Customer Mindset Metrics to Boost Consumer Spending: A Cross-Country Study on Routes to Economic and Business Growth

The relationship between customer mindset metrics (CMMs) and consumer spending has been extensively investigated at the consumer and firm level, but little is known about it at the national level, nor about how it differs between countries. Drawing on five publicly available datasets gathered in 10 European countries over 20 years, our study traces the connections between three CMMs – customer satisfaction, perceived service quality and loyalty intentions – and consumer spending, as well as examining the moderating cross-country effects of culture, socioeconomic factors, economic structure and political–economic elements. The results show that the CMMs significantly influence consumer spending in all the countries studied, with the effects most pronounced in societies with relatively low education levels, a dominant service sector, fewer barriers to business and international trade and a foundation of survival values rather than self-expressive values. Our findings suggest that CMMs can be used to boost not just business performance but also economic growth, and therefore have significant implications for policymakers as well as practitioners and companies.     

SEIR Model to address the impact of face masks amid COVID-19 pandemic

Early in the pandemic of coronavirus disease 2019 (COVID-19), face masks were used extensively by the general public in several Asian countries. The lower transmission rate of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Asian countries compared with Western countries suggested that the wider community use of face masks has the potential to decrease transmission of SARS-CoV-2. A risk assessment model named Susceptible, Exposed, Infectious, Recovered (SEIR) model is used to quantitatively evaluate the potential impact of community face masks on SARS-CoV-2 reproduction number (R₀) and peak number of infectious persons. For a simulated population of one million, the model showed a reduction in R₀ of 49% and 50% when 60% and 80% of the population wore masks, respectively. Moreover, we present a modified model that considers the effect of mask-wearing after community vaccination. Interestingly mask-wearing still provided a considerable benefit in lowering the number of infectious individuals. The results of this research are expected to help public health officials in making prompt decisions involving resource allocation and crafting legislation.
