Research on the Effect of Executives as Audit Committee Members on Internal Control Weakness
Authors: Li Yange
Published: November 2021

The Audit Committee is a specialized agency under the Board of Directors, and supervising the company's internal control is one of its duties. This article takes the 2012-2017 Shanghai-Shenzhen A-share non-financial listed company as a research sample, focusing on the chairmen, CEOs, CFOs, board secretaries and executive directors other than the CEO, discussing the impact of their concurrent appointment as audit committee members on the arising, correction and repair of internal control weakness in listed companies. The study found that different types of executives who are concurrently members of the audit committee would lead the internal control weakness to different directions. In general, excluding some less significant results, executives concurrently serve as members of the audit committee could stimulate the arising of internal control weakness and promote the correction and repair of the existing internal control weakness of the listed company. This indicates that when a listed company does not have internal control weakness, its executive layer intervention will weaken the effectiveness of the audit committee's governance and induce the arising of internal control weakness. Conversely, when the company inherently has internal control weakness, the intervention will strengthen the effectiveness of the audit committee's governance, making the audit committee more effective in monitoring internal control weakness. In addition, an important finding is that the existence of the Secretary of the board among the members of the audit committee will limit the chairs’ role in promoting internal control deficiencies.
An Exploration of Realized Volatility and Returns in the Chinese Stock Market
Authors: Shi Kuaile
Published: November 2021

This paper uses high-frequency stock index data to construct realized volatilities for the Chinese stock market and applies in-sample and out-of-sample  to test the predictive power of realized volatility on Chinese stock market returns. The empirical results show that realized volatility can significantly predict the excess return of the Chinese stock market in the next month, and the in-sample and out-of-sample regression models  are positive, and the out-of-sample  The p-value of the regression model is significant. And after controlling for a range of other stock predictor variables, we find that the regression coefficient of realized volatility is still significant, and we find that after adding realized volatility, the in-sample adj-  increases with the inclusion of realized volatility, suggesting that realized volatility does have components that are not explained by other economic variables. Also based on a different construction method, the realized variance still has significant predictive power after averaging the realized variance. After combining two different realized variance indicators, the predictive power is still better. In terms of economic interpretation, this paper finds that the predictive power of realized variance on stock returns is through influencing the turnover rate (market trading activity), which in turn influences stock market returns. We find that realized volatility has a significant effect on the turnover rate, and when we use realized volatility to predict the turnover rate, which in turn predicts the excess return, we find that the coefficient is highly significant, indicating that realized volatility can indeed cause changes in excess return by affecting the turnover rate.

Published: November 2021

In today's new world situation, the consumption structure of energy is constantly changing. All countries attach importance to the use of new energy, vigorously promoting the development of new energy-related industries.Traditional energy and new energy are interchangeable, so there is a complex relationship between crude oil futures market and new energy stock market. China, as an economy with strong energy demand and high dependence on oil, will be affected by changes in oil futures prices. America's new energy policy has two striking sides. On the one hand, due to the lack of consensus, the US has so far failed to come up with new energy development plans and targets at the national level. On the other hand, a series of supportive policies launched by the federal and local governments have enabled the U.S. wind and solar industries to maintain a high growth rate in recent years. In view of this, the research takes WTI crude oil price, Zhongzheng New energy Index and China crude oil price as the research object, analyzes the interaction among them by using VAR model and GARCH model, and predicts the volatility of crude oil price and new energy stock price.

Business Efficiency Evaluation of Machine Tool Manufacturers by Data Envelopment Analysis (DEA): A Case Study of Taiwanese Listed Machine Tool Companies
Authors: Chen Jui-Lung
Published: November 2021

Data envelopment analysis (DEA) is widely used to measure the business efficiency of many industries, among which the Taiwanese machine tool industry is well-known for its complete supply-chain system. Relying on DEA and Malmquist Productivity Index to analyze the business efficiency of Taiwanese listed machine tool manufacturers from 2018 to 2019, this study compared the changes in their business efficiencies and productivities. According to the five change indicators of Malmquist, only the technical efficiency, pure technical efficiency, and scale efficiency of the overall industry posted some growth during the research period, showing that the whole industry is actively improving its technical efficiency and striving to achieve the scale efficiency. However, technical change and total factor productivity declined slightly, indicating that the industry still makes more technical progress. Thus, companies should adjust their inputs and outputs to improve the production boundary for technical progress. The purposes of this study are to identify the success factors of the excellent performance of manufacturers and the benchmarking indicators of the decision-making unit on the efficient frontier results to provide some references for formulating future business strategies and direction.
Tick Size and Informed Trading: Evidence from the Taiwanese Stock Market
Authors: Duan Chang-Wen , Hung Ken , Liu Shinhua
Published: November 2021

We adopt the Sandås model for order-book equilibrium to examine informed trading on the Taiwanese stock market, a purely order-driven call-auction market. We find that adverse-selection cost is low for well-known stocks with high liquidity and low volatility, but cost is high for monitoring the order books of those stocks. Our empirical results show that the impact of adverse selection is greatest at the beginning of each trading day and that informed traders engage in stealth trading, supporting the stealth trading hypothesis. Finally, with the special tick size rules on the market, both adverse-selection cost and monitoring cost decline as tick size decreases.
Coinfection of Bartonella spp. and Borrelia Burgdorferi in Ixodes Scapularis Using PCR Assay, a Case Study in Nova Scotia
Authors: Kho James , Colbourne Chelsea , Bent Emma , Nabbout Amal El , Rossolimo Tatiana
Published: November 2021

Coinfection of vector species can provide more insight into the complex relationship between zoonotic pathogens and its host. Ixodes scapularis (Say) or the deer-tick in particular is an important species in North America because of its exceptional ability as a vector that can transmit zoonotic diseases such as Lyme and Cat Scratch Disease (CSD). In recent years, many studies have suggested a possible link between the coinfection of Borrelia burgdorferi, the causative agent of Lyme, with other tick-borne bacteria such as Bartonella spp., the causative agent of CSD, as partly responsible for the symptoms associated with Chronic Lyme Disease or Post-Treatment Lyme Disease Syndrome. This study investigates the prevalence of Bartonella spp. and Borrelia burgdorferi in Ixodes scapularis using Polymerase Chain Reaction (PCR) assay to potentially find a link between the two of the most common tick-borne pathogens found in Nova Scotia. Standard PCR using primers targeted at the two bacterial species were conducted on 157 I. scapularis ticks collected in Nova Scotia. Overall, we found high prevalence for both bacteria at 75.16% for Bartonella spp. and 47.13% for B. burgdorferi with no significant differences between the sex of the ticks. Interestingly, all the ticks positive for B. burgdorferi were also positive for Bartonella spp. which implies that the coinfection rate between B. burgdorferi and Bartonella spp. is 47.13%. We report one of the highest coinfection rates for B. burgdorferi and Bartonella spp. in I. scapularis, consistent with the current trends of increasing tick presence in North America.
Cutlink Cleaning Head with a Spreading Feature for Biological Sprout Control
Authors: Hamberg Leena , Strandström Markus , Saksa Timo
Published: November 2021

The ability of deciduous trees to sprout efficiently after cutting is problematic in young forests where the target is to cultivate coniferous trees for industry. Since the use of chemicals has been restricted, new alternatives are needed. One potential and environmentally friendly option is biological sprout control that is based on the use of a white-rot fungus, Chondrostereum purpureum (Pers. Ex Fr.) Pouzar. This method has been efficient in earlier investigations when performed manually, but efficient, fully mechanized devices which are able to cut and treat stumps with a fungus are still unavailable. Therefore, the efficacy of biological sprout control conducted with a Cutlink cleaning head equipped with a spreading feature was studied in two young Norway spruce (Picea abies (L.) H. Karst.) forests in central Finland.Sample plots for the control (cutting deciduous saplings only) and fungal treatment (cutting and spreading fungal inoculum on fresh stump surfaces) were established, and the ability of the Cutlink cleaning head in preventing sprouting of silver and downy birch (Betula pendula Roth and B. pubescens Ehrh., respectively) in the sample plots was investigated for two years.In the near vicinity of cultivated Norway spruce, the proportion of cut deciduous saplings varied from 50–60% after the Cutlink operation. The average mortality of silver and downy birch stumps in the fungal treatment plots was ca. 40%, while stump mortality in the control, i.e., cutting only, was only ca. 13%, after two years. Stump mortality increased up to 73% if the stumps did not include old branches, i.e., the stump was cut to a low enough height.These results confirmed that the Cutlink cleaning head is a potential tool in young stand management operation but further development will be needed in working methods in order to achieve lower stump heights (no branches on the stump) and also to increase the proportion of cut saplings.
Energy balance modelling of high velocity impact effect on composite plate structures
Authors: Al-Waily M. , Jaafar A.M.
Published: November 2021

Purpose: In many military applications, composite materials have been used because of their high velocity impact resistance that helps absorption and dispersion energy. It is therefore used in armour and vehicles, aircraft and spacecraft that are subjected to impact of various shapes and velocities.
Design/methodology/approach: In the theoretical part, the absorption energy equation for the sample was established by constructing an energy balance equation consisting of five types of energies, it is the compressive energy in the first region (the impact region), the tensile energy in the first region, the tensile energy in the second region, the energy of the shear plugging and the friction energy.
Findings: It was found in the experiments that the tensile stress value increased by increasing the volume fraction of fibres to the polyester, and the value of compressive stress decreased. Also manufactured different types of impact samples with dimensions
(20*20 cm2 ) and deferent thickness. The results were an increase in the amount of energy absorbed by increasing the ratio of the fibre to the polyester. It is found that the greatest effect in the equation of energy balance is the shear plugging energy, in which the value of the energy absorbed reached 38% of the total energy. And in the second degree friction energy, in which the value of the energy absorbed reached 27% of the total energy. while the other energies are relatively small but with important values, except for the tensile energy in the second region, the Kevlar-Polyester (40-60)%, so that the increase was more than four times the previous case.
Research limitations/implications: Three types of reinforcing fibres were used: Kevlar, Carbon and Glass fibres with a matrix material as polyester. Six samples are made for tensile and compression testing, Kevlar-Polyester (30-70)%, Carbon-Polyester (30-70)%, Glass-Polyester (30-70)%, Kevlar-Polyester (40-60)%, Carbon-Polyester (40-60)% and Glass-Polyester (40-60)%.
Practical implications: On the experimental part, experimental work tests were carried out to determine the mechanical properties of the samples such as tensile and compression tests as well as conducting the natural frequency test conducting the impact test by bullet to identify the effects and penetration incidence and compare this with the theoretical results.
Originality/value: In this research high velocity impact is used with a bullet it diameter 9 mm, mass of 8 g, and a semi-circular projectile head with a specific velocity ranging from 210-365 m/s. The effect of the impact is studied theoretically and experimentally. The elastic deformation is increased for increasing the ratio of the fiber to the polyester and the depth of penetration is decreasing. The hybrid sample is affected in absorption energy and decreasing the penetration. Finally calculated for penetration behaviour theoretically and experimentally for different composite materials and comparison for the results calculated.

Authors: Rezaeipour Mohammadreza , Apanasenko Gennady Leonidovich , Banparvari Maryam
Published: November 2021

Background: There are controversial studies on weight loss, cardiometabolic markers, and quality of life (QOL) in obese aged women participating in water sports. Objectives: This study aimed to determine the effects of the WATERinMOTION exercise program accompanied with no diet on the inactive obese aged women’s weight, cardiometabolic markers, and QOL. Methods: Sixty-four inactive obese aged women were recruited to participate in this cross-sectional study at the Ukrainian Sports Center, Kyiv, 2019. They were randomly assigned into two Case (n = 32, with the WATERinMOTION aquatics exercise program) and control (n = 32, held in a sitting position simultaneously) groups using the convenient sampling method. The two programs were run twice a week (55 minutes each time) and lasted for one month. Moreover, anthropometric indices (weight, height, waist circumference), cardiometabolic markers (blood lipid markers and glycaemia), QOL (SF-36 questionnaire), and dietary monitoring were assessed before and after the intervention. Results: The groups did not differ significantly regarding each of the analyzed variables prior to the intervention. Comparing pre-and post-intervention results revealed significant weight loss (-1.3, P = 0.004) and average BMI (-0.4, P = 0.002) in the case group. Moreover, a significant variation was revealed only in terms of weight after the intervention (P = 0.001). Regarding QOL, improvements in health status, vitality, and social aspects were significant in the case group after the intervention. Conclusions: The present study suggests that the WATERinMOTION program accompanied with no diet has a positive effect on weight loss, waist circumference, and metabolic profiles in obese aged women. However, the improvement in the QOL should not be neglected.

The aim of this study was to investigate the determinants of influenza vaccination using HBM in HCWs of Jahrom hospitals. This cross-sectional study was performed by multicenter method on 614 HCWs in Jahrom, southern Iran, in 2020. Data collection tools included Demographic and researcher-made Influenza Vaccination in HCWs Based on HBM Questionnaires whose validity and reliability were measured and evaluated. Analyzes have been performed using SPSS 21. Increasing age (P < 0.001) and perceived barriers (P < 0.001) have increased influenza vaccination, but perceived benefits (P = 0.002), cues to action (P = 0.001), and self-efficacy (P < 0.001) have had a negative impact on influenza vaccination among HCWs. Perceived severity (P = 0.7) was higher in people with a history of influenza vaccination, while such a difference was not observed in perceived susceptibility. Higher mean age, previous vaccination history, and perceived barriers are predictors of influenza vaccine participation behavior.

The Pact on Migration and Asylum as a the foundation of the new migration policy of the European Union
Authors: Rybakov Andrew Vyacheslavovich
Published: November 2021

The relevance of the selected topic is substantiated by the fact that in modern world migration has become a significant factor in the development of both accepting countries and countries of origin. Europe hosts the largest number of migrants. Since 2015, the EU member-states have been experiencing strong migration pressure. The existing migration stands in need for reform. The New Pact on Migration and Asylum should be a significant step towards creating a reliable and effective system for regulation of migration. The subject of this research is the institutional and legal characteristics of the EU New Pact on Migration and Asylum. The article analyzes the proposals of the European Commission regarding the migration policy reform, as well as the political-legal mechanism for their implementation; contradictions between the member-states in the course of the relevant discussions. The following conclusions are made: 1) It must be admitted that the new approach of the European Commission is comprehensive and aimed at integration of the internal and external aspects of migration policy. 2) The structure of the Pact corresponds to the goals of migration policy and consists on three levels – external, namely relations with the countries of origin and transit of migrants; control over the external borders of the EU; a new system of permanent solidarity. 3) As an annex to the New Pact on Migration and Asylum, the European Commission has presented a roadmap for implementation of various proposals. However, by the end of 2021, the schedule for the adoption of legal documents is not being maintained. 4) The only common denominator between the different groups of countries is the orientation towards external actions aimed at curbing migration movements prior to their arrival to Europe. 5) The plan of the European Commission on adoption of rules obligatory for all member-states currently seems untenable, considering the clashing interests.

The transaction price of a land property with commercial buildings depends on both its quantitative and qualitative attributes. Quantitative attributes include surface areas of plots of land and usable floor spaces of premises and buildings with various intended purposes, as well as values of rents. Qualitative attributes are represented by the global attributes of these properties.In the analysis of the land property market with commercial buildings, all pairs that relate a transaction price to individual attributes are considered. The market value prediction is based on multiple regression analysis for a two-dimensional random variable, represented by the price and the predetermined attribute. The final market value of the property being valued is calculated as the weighted average of the market values predicted for each attribute.This research paper presents the procedure for determining the market value of land with commercial buildings, which falls within the method of statistical analysis of the market. The derived formulas and substantively justified algorithms may be the basis for market analysis and estimation of the market value of such land. This procedure has been thoroughly verified using two practical numerical examples.

Rapid urbanization combined with high economic growth, industrialization, and changes in socio-economic conditions increase the quantity of municipal solid waste. Cities located in South-Asia are facing serious issues due to waste, with countries like India, Bangladesh, and Pakistan top of the list of bad waste management. The increasing generation of solid waste and also the improper management of waste in Bangladesh leads to environmental degradation. Current waste management practice in Bangladesh is so weak that day by day it is harming the climate and creating a lot of unwanted situations. This research consists of an examination of the current administrative measures and presents another proposition for the executive cycle to decrease ecological contamination. The research study aims to decrease the amount of waste being dumped into municipal sanitary landfill sites & converting the waste into energy which is both financially and environmentally suitable by involving unemployed people in the management system. The results of this study will give an idea of how waste can be utilized as a resource and how this resource can be a capital good as well as how the local level problems can be solved by taking some strategies and making our environment suitable for future generations.

Groundwater is a precious source of fresh water and a major component of the entire water supply. Both water quality and quantity could be satisfied by evaluating the groundwater potential sites (GWPS). This paper analyzes the ground-water potentials in a semi-arid region of Khyber Pakhtunkhwa, Pakistan. It describes a standard methodology to identify and map GWPS using integrated Geographical Information System (GIS) and remote sensing (RS) methods. Eight parameters including elevation, slope, drainage density, lineaments density, soil, geology, land use/land cover and rainfall were integrated to explore areas with groundwater holding capability. GWPS were delineated through subjective weights assigned after coupling various thematic layers using Saaty’s Analytical Hierarchical Process (AHP). The modelled GWPS were cross-checked with tube wells data. The result indicates that the central part of the study area has good potential for groundwater reserves/exploitation, where the factors i.e. moderate to high drainage density, sedimentary sequence of alluvial plain, low elevation etc. discern the central portion of the study area as a suitable site for groundwater. This study suggests that the applied method proves to be very significant and reliable tool for timely assessment of quality assured evaluation of groundwater resources. This study could be a systematic guide for future investigations for water related explorations, especially in semi-arid environments.

The article presents the results of research and work related to the implementation of the research and development project POIR.01.01.01-00-0120/17 co-financed by the EU, through the NCBR, entitled: Innovative technology using thermal analysis, TDA, of self-feeding manufacturing of high-quality cast iron to produce new generation, enhanced performance casts. In many foundries, thermal derivative analysis (TDA) is used in addition to chemical analysis to evaluate the physical and chemical properties of an alloy while it is still in the melting furnace or ladle and before it is poured into the mold. This fact makes it possible to improve the metallurgical quality of the alloy by introducing alloying additives, carburizers or modifiers into the furnace as part of the pre-modification or primary or secondary modification in the ladle or when pouring into molds. Foundry machinery (modifier dosing systems and spheroidizing station) is very important in these operations. Only the full synergy of modern equipment with modern technology ensures high quality and repeatability of the casting process. The article mainly discusses the obtained parameters of TDA analysis (with the use of the ITACA system) at different stages of melting and how to improve them by using modern and fully automated dosing systems (Itaca OptiDose, ItacaWire and ItacaStream). Special attention was paid to the minimum temperature of the eutectoid. The change of its value after the modification process, its influence on the quality of the melted metal, a very strong correlation with the number of nuclei and the number of graphite precipitations in the casts were shown.
