The Effects of Temperature and Humidity on the Survival and Development of the European Rabbit Flea, Spilopsyllus-Cuniculi (Dale)
Publisher: CSIRO Publishing
Date: 1988
DOI: 10.1071/ZO9880649
Abstract: The development of rabbit fleas from eggs to adults is strongly influenced by both temperature and relative humidity. Normal development only occurs if the temperature is between 15 and 30�C and humidity lies between 70 and 95% RH. This is consistent with the ecology of flea larvae which develop in the rabbit's nest where young rabbits generally maintain a warm, humid environment. At 27�C new adult fleas emerge from pupae about 21 days after egg laying. If environmental air becomes too dry, the water content of the air, even in the rabbit nest, may not always be sufficient to maintain a sufficiently moist microclimate in the nest for the flea larvae. Adult fleas do not appear to have high tolerance to heat or desiccation and, in the more arid parts of Australia, if they left the rabbits during the summer the microclimate of burrows is likely to be too harsh for them to persist.
Factors Affecting Undergraduates’ Academic Performance during COVID-19: Fear, Stress and Teacher-Parents’ Support
Publisher: MDPI AG
Date: 24-06-2022
DOI: 10.3390/SU14137694
Abstract: The emergency transition from physical to online learning during COVID-19 has affected university students in various aspects, especially their academic performance. It can be caused by many factors, such as in idual, environmental and social factors. Therefore, this study aims to determine the impact of fear, stress, well-being, teacher and parents’ support (independent variables) on undergraduates’ academic performance (dependent variable) during the COVID-19 pandemic. A structured online questionnaire has been developed and administered to 400 undergraduates. A structural equation model that integrated all variables under investigation was built and statistically validated using AMOS. The results demonstrated that well-being, teacher emotional support and teacher academic support have the highest significant impact on the respondents’ academic performance. It can be concluded that teachers’ support is the most substantial influence in ensuring student learning sustainability during the COVID-19 pandemic.

Adolescent Obesity Modeling: A Framework of Socio-Economic Analysis on Public Health
Publisher: MDPI AG
Date: 22-07-2021
DOI: 10.3390/HEALTHCARE9080925
Abstract: Bayesian Structural Equation Modeling (SEM-Bayesian) was applied across different research areas to model the correlation between manifest and latent variables. The primary purpose of this study is to introduce a new framework of complexity to adolescent obesity modeling based on adolescent lifestyle through the application of SEM-Bayesian. The introduced model was designed based on the relationships among several factors: household socioeconomic status, healthy food intake, unhealthy food intake, lifestyle, body mass index (BMI) and body fat. One of the main contributions of this study is from considering both BMI and body fat as dependent variables. To demonstrate the reliability of the model, especially in terms of its fitting and accuracy, real-time data were extracted and analyzed across 881 adolescents from secondary schools in Tehran, Iran. The output of this study may be helpful for researchers who are interested in adolescent obesity modeling based on the lifestyle and household socioeconomic status of adolescents.
