This work applies a novel geometric criterion for global stability of nonlinear autonomous differential equations generalized by Lu and Lu (2017) to establish global threshold dynamics for several SVEIS epidemic models with temporary immunity, incorporating saturated incidence and nonmonotone incidence with psychological effect, and an SVEIS model with saturated incidence and partial temporary immunity. Incidentally, global stability for the SVEIS models with saturated incidence in Cai and Li (2009), Sahu and Dhar (2012) is completely solved. Furthermore, employing the DEDiscover simulation tool, the parameters in Sahu and Dhar'model are estimated with the 2009-2010 pandemic H1N1 case data in Hong Kong China, and it is validated that the vaccination programme indeed avoided subsequent potential outbreak waves of the pandemic. Finally, global sensitivity analysis reveals that multiple control measures should be utilized jointly to cut down the peak of the waves dramatically and delay the arrival of the second wave, thereinto timely vaccination is particularly effective.This study analyses the causal and long-run linkage between air transport and economic growth. It was conducted to validate the tourism-led growth hypothesis for the United States (US) during the period 1981-2017 and includes Information and Communication Technologies (ICTs) alongside coal rents in the tourism-led growth hypothesis. This study presents a new direction for future studies by considering the relevance of the fourth industrial revolution (Industry 4.0), particularly in the US. To achieve the stated claim, this study considers as additional explanatory variables how ICTs moderate the impact of Foreign Direct Investment (FDI) on GDP. Protein Tyrosine Kinase inhibitor The empirical result confirms a connection between the Industry 4.0 era and the role of ICTs, which promotes substantial changes in the way of life and productivity. This has led to a vast technological advancement, which is in line with but at a faster pace than the technological advancement of previous revolutions. From empirical results, the study provides relevant policy recommendations related to the role of natural resources, new technologies and tourism on US GDP, while it also provides evidence of the positive effect of ICTs over FDI under the Industry 4.0 era.A high-precision geologic time scale is the essential key for understanding the Earth's evolutionary history and geologic processes. Astronomical tuning of orbitally forced stratigraphic records to construct high-resolution Astronomical Time Scales (ATS) has led to a progressive refinement of the geologic time scale over the past two decades. In turn, these studies provide new insights regarding the durations and rates of major Earth events, evolutionary processes, and climate changes, all of which provide a scientific basis for contextualizing and predicting future global change trends. South China hosts some of the best-exposed and well-dated Neoproterozoic through Mesozoic stratigraphic sections in the world; many of which are suitable for cyclostratigraphy and calibrating the geologic time scale. In North China, several Cenozoic oil-bearing basins have deep boreholes with continuous sampling and/or well logging that enable derivation of astronomically tuned time scales for an improved understanding of basin evolution and hydrocarbon generation. This Special Issue focuses on case studies of astrochronology and applied cyclostratigraphy research using reference sections within China. In this introductory overview, we (1) summarize all existing astrochronology studies of the Neoproterozoic through Cenozoic sections within China that have been used to enhance the international geologic time scale, (2) examine briefly the astronomically forced paleoclimate information recorded in various depositional systems and the modern techniques employed to analyze the periodicity of these signals encoded within the sedimentary record, and (3) summarize the 20 contributions to this Special Issue of Palaeogeography, Palaeoclimatology, Palaeoecology on 'Cyclostratigraphy and Astrochronology Case studies from China'.Low motivation to learn in undergraduate general education courses hinders learning. Research has identified strategies that increase motivation to learn before students are asked to learn content (e.g., outlining the utility of the course material for future careers). Extending this work, we propose that learning any material in a course may beget motivation to learn more, in line with the notion that the process of learning itself may spark curiosity and interest. Across three populations (college-aged individuals on mTurk, large public university students, and small private university students), we found that watching a TED Talk video (i.e., exposure to new information, learning) pertaining to any topic led to an increase in motivation to continue learning about that topic and other topics more generally. These results reveal a need to broaden models of motivation to consider the importance of exposure to content to increase motivation to learn. With increasing prevalence of coronavirus cases (including among health care providers), the current advice for orthopaedic surgeons is to favor non-operative management of most injuries and reduce face-to-face follow-up. We present our experience in managing the patients at Government-run non-COVID-19 trauma center in Delhi in an algorithmic form. Our standard operating protocols were mainly based on recommendations of Indian Orthopaedic Association and targeted to provide healthcare at a minimum risk to the treating team as well as other patients admitted to the hospital. We describe the inflow, in-hospital management and outflow of patients at our facility during the lockdown period and in the following unlock period (from 23 March to 8 July 2020). Those patients who had absolute indications for surgery were offered surgery, while conservative treatment was more favored in those with relative indications. We also highlight the changes incorporated in OT settings as well as in rehabilitative and follow-up period. Following the described protocol helped us maintain a balance between the safety of patients and our front line workers which was evident by very low COVID-19-positive rate in admitted patients (4.22%) and health care providers (16.67%) in the above-mentioned time period. We need to be prepared to cohabitate with this deadly Novel Coronavirus and adapt our surgical practices according to the need of the hour by minimizing surgical indications and strengthening the training in conservative principles.We need to be prepared to cohabitate with this deadly Novel Coronavirus and adapt our surgical practices according to the need of the hour by minimizing surgical indications and strengthening the training in conservative principles.
