Aspects of writing knowledge and EFL students' writing quality

Writing knowledge pertaining to process, system, content, and genre plays an essential role to produce an intelligible composition. The purpose of the present study is twofold – to investigate the correlation between aspects of writing knowledge and quality of writing, and to investigate the contribution of the overall and individual aspects of writing knowledge to writing quality. The participants were 54 second-year ELT undergraduate students of a university in Indonesia. A writing test and multiple-choice test on writing knowledge were used as the instruments of data collection. The analysis employed Pearson correlation coefficient and multiple regressions. The result revealed a significant positive correlation between writing knowledge and writing quality. As a unit, the knowledge of process, system, content, and genre, indicates a significant contribution to the writing quality. Individually, however, only process knowledge significantly contributes to the writing quality. It provides additional pieces of evidence that process knowledge be given special attention, thus writing instruction should allow students to learn writing knowledge explicitly and implicitly.

Assisting SMEs to Establish RMA Diagnosis Checklist and Innovative RMA Process System to Enhance B2B Innovative Concept Adaptation and Its Value-Added Function

This research attempts to focus on Return Merchandise Authorization (RMA) and the optimization of the RMA solutions. In the meantime, this research establishes RMA Diagnosis Checklist, Innovative RMA Process system, and a number of suggested solutions for Small and Medium Enterprises (SMEs). This research has important implications as it optimizes RMA solutions to B2B problems for SMEs, provides useful information on effective RMA service policies for B2B marketing decisions and creates a general awareness of the importance and rationale of RMA. Finally, this study provides RMA as a diagnostic tool and strategic tactic for SMEs.

AHP Based Grassroots Emergency Response Capability Evaluation Index System Construction

The primary and secondary catastrophes of emergencies, as well as their comprehensive disasters, add a significant deal of complexity and risk to the grassroots emergency response system’s creation. The completeness of the emergency response system development is significantly related to improving the basic capacity of grassroots emergency security. The weight comparison calculation and analysis of the links at all levels in the emergency response system is carried out using the hierarchical analysis method based on the basic experience of current domestic related fields for the construction of the emergency response process system, and the results of the relative importance ranking of indicators are obtained, and this is used to provide emergency response and emergency management decision makers with emergent information.

Implementation of a PID Type Sliding-Mode Controller Design Based on Fractional Order Calculus for Industrial Process System

This paper is devoted to designing a fractional order Proportional Integral Derivative (PID) type sliding mode control method (FO-PIDSMC) for a non-linear liquid level coupled tank process system. By considering the individual advantages of the FO calculus and PID type SMC method, this proposed FO-PIDSMC technique is designed to integrate the FO calculus method with PID type SMC scheme to obtain an accurate and robust liquid level tracking in terms of the predefined reference trajectory. The real-time experimental results of the proposed controller suggest a dramatic improvement over the traditional process system controller methods in both trajectory tracking and required control action.

How to Dispose of Medical Waste Caused by COVID-19? A Case Study of China

The rapid increase in novel coronavirus (COVID-19) patients also means a rapid increase in medical waste that could carry the novel coronavirus (SARS-CoV-2). How to safely dispose of medical waste caused by COVID-19 is a huge challenge that needs to be solved urgently. The outbreak of the COVID-19 has led to a significant increase in the daily generation of medical waste in China and has placed a severe test on the Chinese medical waste disposal system. Unlike ordinary wastes and garbage, medical waste that is untreated or incompletely treated will not only cause environmental pollution, but also directly or indirectly cause infections and endanger people’s health. Faced with difficulties, the Chinese government formulated a policy for medical waste management and a response plan for the epidemic, which provides policy guarantee for the standardized disposal of epidemic medical waste. In addition, the government and medical institutions at all levels formed a comprehensive, refined, and standardized medical treatment process system during research and practice. China has increased the capacity of medical waste disposal in various places by constructing new centralized disposal centers and adding mobile disposal facilities. China has achieved good results in the fight against COVID-19, and the pressure on medical waste disposal has been relieved to a certain extent. However, the global epidemic situation is severe. How to ensure the proper and safe disposal of medical waste is related to the prevention and control of the epidemic situation. This study summarizes China’s experience in the disposal of medical waste in the special case of COVID-19 and hopes to provide some reference for other countries in the disposal of medical waste.
