The connection between heart rate variability (HRV), neurological health, and cognition: A literature review

The heart and brain have bi-directional influences on each other, including autonomic regulation and hemodynamic connections. Heart rate variability (HRV) measures variation in beat-to-beat intervals. New findings about disorganized sinus rhythm (erratic rhythm, quantified as heart rate fragmentation, HRF) are discussed and suggest overestimation of autonomic activities in HRV changes, especially during aging or cardiovascular events. When excluding HRF, HRV is regulated via the central autonomic network (CAN). HRV acts as a proxy of autonomic activity and is associated with executive functions, decision-making, and emotional regulation in our health and wellbeing. Abnormal changes of HRV (e.g., decreased vagal functioning) are observed in various neurological conditions including mild cognitive impairments, dementia, mild traumatic brain injury, migraine, COVID-19, stroke, epilepsy, and psychological conditions (e.g., anxiety, stress, and schizophrenia). Efforts are needed to improve the dynamic and intriguing heart-brain interactions.

The Intersection of Fashion, Immersive Technology, and Sustainability: A Literature Review

Fashion industry emissions, resource use, and waste are attracting increasing consumer and government attention, with broad agreement that a new approach is required along the supply chain. Following the COVID-19 pandemic, a move to digitalisation facilitated an accelerating interest in digital applications, including immersive technologies such as augmented and virtual reality. This systematic literature review explores the intersecting topics of fashion, immersive technologies, and sustainability to determine the trends, examine the solutions offered, and discuss the implications of immersive technologies for sustainability. Four resources were consulted (Scholar, SCOPUS, WOS, and ProQuest), resulting in 74 articles for the review. Grey literature was included due to the currency of the topic and gaps in the available academic literature. The findings highlight immersive technology uses in the fashion industry, which are part of a move towards sustainability. These technologies are used to reduce online returns, educate consumers, reduce waste in design and manufacture, and remove the need for physical items. However, issues include high energy costs, consumer reluctance, and skill shortages. Results suggest future research and industry discussions should focus on empirical studies to measure the sustainability impact of immersive technologies, monitor technology diffusion and uptake, and measure the industry skills gap.

Do you know your partner's personality through virtual collaboration or negotiation? Investigating perceptions of personality and their impacts on performance

Interpersonal skills, including collaborative problem solving (CPS) and negotiation skills, are essential in many aspects of the 21st century. With the rapid development of technologies in the past decades, it has become increasingly prevalent for collaborations, negotiations, and communications to occur virtually. Furthermore, the COVID-19 pandemic accelerated the shift from in-person interactions to virtual interactions. On the other hand, personality traits, enduring characteristics of individuals that are largely stable over time, affect a wide variety of human behaviors, including how people interact with each other. In this study, we investigated the extent to which team members' personalities, the heterogeneity in personalities among team members, and the interaction processes in virtual tasks impacted performance on these tasks with limited exposure to personal information such as appearance and voice. In addition, we examined how one perceived the team partner's personality and how people tended to project their own personality onto partners during the short-term virtual interactions. Findings suggested that higher heterogeneity in personality between partners was associated with better team negotiation performance, while it was not associated with collaboration outcomes in the CPS task. Implications of the findings and limitations of this research were also discussed. • We study how team members' personalities and the interaction processes impact performance on virtual tasks. • Relationships between personality, interaction processes, and performance differ in collaboration and negotiation contexts. • People tend to project their own personality traits onto their online partners during short-term virtual interactions. • Teams that are more heterogeneous in personality show better negotiation outcomes.

Sex differences and psychological stress: responses to the COVID-19 pandemic in China.

BACKGROUND: About 83,000 COVID-19 patients were confirmed in China up to May 2020. Amid the well-documented threats to physical health, the effects of this public health crisis - and the varied efforts to contain its spread - have altered individuals' "normal" daily functioning. These impacts on social, psychological, and emotional well-being remain relatively unexplored - in particular, the ways in which Chinese men and women experience and respond to potential behavioral stressors. Our study investigated sex differences in psychological stress, emotional reactions, and behavioral responses to COVID-19 and related threats among Chinese residents. METHODS: In late February (2020), an anonymous online questionnaire was disseminated via WeChat, a popular social media platform in China. The cross-sectional study utilized a non-probabilistic "snowball" or convenience sampling of residents from various provinces and regions of China. Basic demographic characteristics (e.g., age and gender) - along with residential living arrangements and conditions - were measured along with psychological stress and emotional responses to the COVID-19 pandemic. RESULTS: Three thousand eighty-eight questionnaires were returned: 1749 females (56.6%) and 1339 males (43.4%). The mean stress level,as measured by a visual analog scale, was 3.4 (SD = 2.4) - but differed significantly by sex. Besides sex, factors positively associated with stress included: age (< 45 years), employment (unsteady income, unemployed), risk of infection (exposureto COVID-19, completed medical observation), difficulties encountered (diseases, work/study, financial, mental), and related behaviors (higher desire for COVID-19 knowledge, more time concerning on the COVID-19 outbreak). "Protective" factors included frequent contact with colleagues, calmness of mood comparing with the pre-pandemic, and psychological resilience. Males and females also differed significantly in adapting to current living/working, conditions, responding to run a fever, and needing psychological support services. CONCLUSIONS: The self-reported stress of Chinese residents related to the COVID-19 pandemic was significantly related to sex, age, employment, resilience and coping styles. Future responses to such public health threats may wish to provide sex- and/or age-appropriate supports for psychological health and emotional well-being to those at greatest risk of experiencing stress.
