Résumé
Background: Corona Viruses is a group of viruses that cause diseases in both humans and mammals and are known to cause chronic respiratory diseases. The viruses among them include SARS, MERS and COVID-19. The most recent pandemic was a result of COVID-19. Older people and those with underlying medical problems are more likely to develop serious illness. Objective(s): To compare the knowledge and practices of Allied Health and Engineering students of the University of Lahore about Corona Virus Disease. Methodology: A cross-sectional questionnaire based survey was conducted on 326 students studying in Allied health Sciences and Engineering departments of UOL. The data was compiled in SPSS, version 24 for analysis. Result(s): The students of Allied Health Sciences had a better understanding and were more aware of COVID-19, its percussions and the methods to prevent its spread than of the Engineering Students. More than half of the Engineering students have found to have less understanding about the causative agent of the COVID-19 and similar trend was found in other categories. Health sciences students showed higher tendency towards hands hygiene practices than engineering students. Practical implication: Lessons learned from different outbreaks of infectious diseases suggested that knowledge and practices towards infectious diseases are associated with level of panic emotion among the population, which can further complicate attempts to prevent the spread of the disease. To facilitate outbreak management of COVID-19 in Lahore, Pakistan, there is an urgent need to understand the public's awareness of COVID-19. Keeping these considerations in mind this research was kicked-off to gauge the knowledge and practices of these medical and engineering students about Corona virus disease. Conclusion(s): The study shows that educational background plays a vital role in disease control and it will help in successful uptake of control interventions for prevention of COVID-19.Copyright © 2023 Lahore Medical And Dental College.

Résumé
This paper investigates the co-movements among precious metals (gold, silver, platinum, and palladium) across time-frequency domains and investment horizons and its implications for dynamic hedging, asset allocation, and utility gains. Based on a multiple wavelet coherence analysis, combined with Dynamic Conditional Correlation Generalized Autoregressive Conditional Heteroscedasticity (DCC-GARCH). The uni-directional co-movement is sequential, running from gold to the remaining metals. Silver leads platinum and palladium in returns, and platinum leading palladium. Interestingly, silver and platinum combined contribute to the variability of gold, while gold, silver, and palladium contribute to the variability of platinum, suggesting that some lead-lag relationships are complex and strengthened by multivariate relationships among the metals. The lead-lag dependence is high at medium and long investment horizons and responds to economic, political, and pandemic shocks to the global economy. We find that a wavelet-based dynamic hedging strategy performs better than a conventional hedging strategy. Portfolio weights from the bivariate, three-dimensional, and four-dimensional wavelet analyses vary across investment horizons. Finally, utility gains are higher at long horizons for all multi-dimensional risk strategies, whereas the utility gains are lower with the onslaught of the COVID-19 pandemic. © 2021 Elsevier Ltd
