Aiming at the problems of low success rate, delay, and high communication cost in distance English teaching resource sharing, this paper puts forward a method of distance English teaching resource sharing based on Internet O2O mode. Based on the model of distance English teaching resource sharing, this paper designs four processes: query, reply, resource substitution, and resource sharing optimization. Experimental results show that the proposed method can achieve high success rate of resource sharing, low latency, communication cost, and high transmission efficiency. Therefore, it is an effective method.

Abstract Prior research has demonstrated the impact of the COVID-19 pandemic on feelings of loneliness, but relatively little is known about loneliness in the context of senior living communities (SLCs). Indeed, the pandemic has led SLCs to enact new safety precautions, including visitor restrictions, intended to reduce the spread of COVID-19, which may have serious consequences for the psychosocial well-being of residents. Drawing on a sample of 733 adults ages 54 to 100 living in one of nine SLCs in December 2020 (response rate = 60%), linear regression models were used to examine whether perceived communication between SLCs and residents during the COVID-19 pandemic influenced feelings of loneliness. Analyses also considered whether this association varied as a function of education. Our findings reveal that 53% of respondents were very lonely during the pandemic. However, older adults who perceived that their SLC had been helpful to their understanding of the pandemic were significantly less lonely (p < 0.01), adjusting for sociodemographic and health characteristics. Moreover, we found that less educated older adults derived the greatest benefit from effective communication about the pandemic (p < 0.05). Those with less education reported feeling lonelier if they did not perceive that their SLC communicated in a way that helped them better understand the pandemic; there was no such association for those with higher education. The findings from this study provide support for the resource substitution hypothesis and demonstrate the importance of communication in alleviating feelings of loneliness during the COVID-19 pandemic.

Abstract Background The decrease of wild reserves and the sharp increase of market demand have led to resource substitution, but it is still not clear how to discover medicinal alternative resources. Here we reveal the biology of medicinal resource substitution in the case of Salvia. Methods A hypothesis was put forward that phylogeny and ecology were the main factors which determined alternative species selection. Phylogenetic analysis was performed based on chloroplast genomes. Spatial climatic pattern was assessed through three mathematical models. Results Salvia miltiorrhiza and alternative species were mainly located in Clade 3 in topology, and their growth environment was clustered into an independent group 3 inferred from principal component analysis. Correlation and Maxent major climate factor analyses showed that the ecological variations within each lineage were significantly smaller than the overall divergent between any two lineages. Mantel test reconfirmed the inalienability between phylogeny and ecology (P = 0.002). Only the species that are genetically and ecologically related to S. miltiorrhiza can form a cluster with it. Conclusions Phylogenetic relationship and geographical climate work together to determine which species has the potential to be selected as substitutes. Other medicinal plants can learn from this biology towards developing alternative resources.

Personality traits are associated with memory in older adulthood: Individuals higher in conscientiousness and openness and lower in neuroticism tend to perform better on memory-recall tasks. We conducted a preregistered study to replicate these associations in a large, multinational cohort and test whether the associations varied by national-level socioeconomic indicators (e.g., per capita gross domestic product). Multilevel modeling was used to analyze data from 71,566 individuals (age: M = 67.9 years, SD = 9.5; 57% women) across 26 European countries and Israel. Higher conscientiousness, openness, and extraversion and lower neuroticism were associated with better memory performance, even when analyses accounted for risk factors including diabetes, hypertension, obesity, emotional disorders, and sleeping problems. Consistent with the resource-substitution hypothesis, results showed that higher conscientiousness and agreeableness and lower neuroticism were associated with better memory in countries with lower gross domestic product. This pattern suggests that psychological (trait) resources may help compensate for country-specific disadvantaged contexts.

Abstract Introduction A weak relation between an increase in education and improved health knowledge was observed among those who attended college, but not among those whose highest educational level attainment was high school (Altindag, Cannonier, & Mocan, 2014). Alachantis and colleagues (2005) had applied cognitive reserve theory (Stern, 2002) to help explain why OSA patients with higher intelligence scores perform well on cognitive tasks. The resource substitution theory (RST; Ross & Mirowsky, 2006) posits that higher education compensates for background disadvantages rather than magnifying background advantages. The goals of the current study were to examine the interaction between educational level and obstructive sleep apnea (OSA) on cognitive functions such as verbal fluency, psychomotor vigilance, executive functions, visuospatial ability, and attention span and to determine whether the results would support the RST. Methods One hundred and nine participants (47 ApneaLinkTM -screened controls and 62 untreated OSA patients) participated in the study and completed the Wisconsin Card Sorting Test, WAIS-III digit span and block design, semantic and phonemic fluency tests, and a psychomotor vigilance task. Subjective sleep (PSQI and ESS) and health measures (depression, anxiety, mood disturbance, diabetes, hypertension) were assessed. A hierarchical regression was conducted to test for the additional variance explained by the interaction term even after accounting for the covariates. Results In semantic fluency and visuospatial ability tasks, patients with higher education performed better than patients with high school or less education. This moderation effect of education was not observed for the control group. A significant interaction effect was not observed for vigilance, phonemic fluency, attention span, or executive functions although education was a significant predictor for all cognitive tasks. Conclusion The resource substitution theory was supported as the benefit of education seemed more crucial for OSA patients than for controls, specifically in semantic fluency and visuospatial ability. This benefit of higher education contributing to larger cognitive reserves in patients with OSA helped buffer some cognitive deficits but not for others, but this buffer no longer works when the cognitive demand gets larger. Support (if any) A grant from the Center for Integrative Research on Cognitive Neural Science, Southern Illinois University Carbondale was received.

Abstract This chapter examines recreational displacement in response to a unique management and biological event: the introduction of the non-native cyprinid tui chub (Gila bicolor pectinifer) into Diamond Lake. The study demonstrates the behavioural reactions of visitors in response to a management action or a 'controlled' decision to intervene in the impacts of the invasive tui chub. About half of the Diamond Lake visitors who still visit the lake exhibited some temporal and/or spatial displacement behaviours. Visitors at Diamond Lake dealt with the lake's closure by remaining at the lake but participating in another activity (activity substitution) or by moving to an alternative location to continue their primary activity (spatial displacement/resource substitution). More than one-third of all Diamond Lake visitors chose not to recreate during that period (temporal displacement) and 17% changed both their activity and location (absolute displacement).
