Abstract: This year is of course the 200th anniversary of Engels’ birth (On November 28). On this special year, it is still necessary to carefully sort out the philosophical heritage left to us by this great man and draw on the ideas that can be used for reference. This paper only discusses the contemporary value of certain viewpoints and theories in Engels' Dialectics. In Engels' concept, dialectics is not only the way we perceive the world, it’s also the property of objective nature. In Engels' view, the basic viewpoint of dialectics is to regard all things as the process of eternal change and movement in the interaction of universal relations. Many of the dialectic thoughts put forward by Engels are consistent with the relevant theories of contemporary science. For example, universal differences necessarily generate universal interaction; the interaction inevitably bases on the intermediary; the overall evolution of things is characterized by the eternal cycle of evolution and degeneration which transform into each other constantly; some thoughts contain the view of holography, and so on. The re-excavation of Engels's views and theories will undoubtedly have great practical significance and value in cleaning up and correcting the separation between man and nature, society and nature caused by the prevalence of contemporary philosophy of consciousness, reducing and preventing all kinds of disastrous consequences brought by it, and further promoting the construction process of theory and practice of human ecological civilization and sustainable development strategy.

Abstract: The novel coronavirus has unsettled many nations and has created severe uncertainty in its spread. In this paper, we present the performance of ensemble models and single forecast models in the projection of COVID-19 confirmed cases in nine countries. Data consisting of two (2) health indicators (new COVID-19 and cumulative COVID-19 confirmed cases) were collated on May 10, 2020 from the Humanitarian Data Exchange (HDX). Forecasting models with the minimum Mean Square Error (MSE) and Root Mean Square Error (RMSE) were selected. Our findings showed that ETS (A, N, N) was the best model fit for China, Spain, South Korea and Ghana in terms of single COVID-19 confirmed cases. On the other hand, INGARCH (1, 1) was the best fit model for the remaining countries. Regarding cumulative COVID-19 confirmed cases, INGARCH (1, 1) was fit for each of the nine countries. Again, we found that single forecasting models outperform hybrid models when the number of data points does not meet a certain threshold, and when the data has no seasonality; suggesting further that hybrid forecast models perform efficiently in complex time series dataset. Results from the 10 days forecast indicate that for most countries, with the exception of Ghana and India, new covid-19 confirmed cases will drop. The study suggest for future works to expand the training dataset by augmenting additional data onto the available data and then apply hybrid forecasting models to the dataset.
