Analysis of Business Strategies of Cross-border E-Commerce under the COVID-19--A Case Study of Koala
Authors: Xiao Yuhan
Published: July 2022

In recent years, the rapid development of China's cross-border e-commerce industry has led to the birth of many cross-border e-commerce platforms, while the outbreak of COVID-19 has brought about a strong impact on both daily life and economic development. In this context, this paper mainly uses the case analysis method and takes Koala as an example to analyse its development strategy's internal strengths and weaknesses as well as external opportunities and threats through SWOT analysis. From the conclusions of the study, it is clear that as a cross-border e-commerce platform, Koala has both unique and universal strengths and weaknesses, while facing the same opportunities and threats as other cross-border e-commerce platforms. This paper not only fills the gap of relatively little research on Koala, but also proposes targeted and innovative suggestions, with a view to enhancing the competitiveness of the company and providing a reference for the future development of the cross-border e-commerce industry.

Applications of Game Theory in Microeconomics
Authors: Lin Yanhao
Published: July 2022

Game theory has been used as a potent analytical tool by numerous areas since its inception. It has been more popular in microeconomic analysis in recent years. It is not an exaggeration to claim that it completely rewrites microeconomics. The major ideas of game theory are summarized in this paper, as well as their application in microeconomics. This study examines the three elements and key types of game theory in its fundamental material. The Nash equilibrium and other equilibria expanded by Nash equilibrium are then reviewed in game theory equilibrium. Then, the Cournot model, Stackelberg model, and Bertrand model are discussed in game theory and market analysis. Finally, in the section on game theory and auction, it explained that, within the context of the game, English auctions and second-price sealed-bid auctions should use comparable strategies, however Dutch auctions and first-price sealed-bid auctions should conceal their own valuations.

The Reviewing of Social Reproduction Theories: Social Capital on Students’ Academic Success
Authors: Hu Jingyue , Wang Shuyu
Published: July 2022

Inequality in human society exists in our lives and influences educational sources. Educational equity is a manifestation of social equity. It is a state of educational development in which a certain society not only gives all members of society freedom and equal choice, but also shares public educational resources at the time and all levels. In fact, education equity should include at least two essential aspects: equality of educational rights and equality of educational opportunities. This article investigates the reasons and phenomena of social reproductions by reviewing some relevant theories of social capital. The main arguments of our research are:1) education is a way of gathering different groups into an average position and helps students benefit from each other. Therefore, the theoretical concepts of social capital influence individual educational success [1], [2] & [3]; 2) Educational competition and social reproduction are caused by unequal educational resources; 3) The academic gap are extended due to various family classes. By reviewing previous research, this article, to some extent, illustrates the cause of social reproductions, which might inspire future researchers.

Published: July 2022

English becomes the universal language, which is a requirement for students to learn. According to several studies and research, the window of critical period for learner to learn is closing. Speaking as one of the parts of English skills is lack of practicing due to dozens of factors. To help students to learn speaking, effective learning theories are developed and discussed by different scholars over period of time. Many early theories are challenged by the later perspectives. To meet students’ needs, this study introduces VR technology and games to be used in teaching. As for VR, it is capable to produce an immersive environment for students to study. Besides, games motivate students to participate and actively engage in the courses. Based on the above views, the application of VR games are suggested in oral English teaching.

Authors: Lu Yi
Published: July 2022

In today's society, many teenagers are being sexually assaulted. In China, influenced by traditional ideas and the existence of exam-oriented education, sex education is still in its infancy and difficult to carry out. Even if some schools carry out sex education courses, there are still many problems, such as the lack of laws, no professional teaching staff, parents' resistance and so on, all of these hinder its development. By contrast, as a country with a long history of sex education, Sweden has a lot to experience and differences with China, such as policy, culture and education system. This paper mainly adopts literature analysis, comparing the differences between Sweden and China in policy, culture and education system to solve the problems in China's sex education. This paper has four parts. The first one illustrates the content of policy, culture and education system. The second elaborates the problems existing in the current sex education in China. The third compares China with Sweden in these three parts. The fourth provides feasible suggestions: special law should be established; social organizations ought to cooperate; media should take the responsibility to propagandize positively; the supervision and management of the curriculum are supposed to be strengthened; families also need to guide their children and participate in sex education.

INTRODUCTION : Le cancer de la prostate fait partie des maladies chroniques non transmissibles qui touche essentiellement les hommes âgés de plus de 50 ans. Son incidence augmente avec l’âge et est connue pour être plus élevée chez les noirs à causes de certaines prédispositions génétiques. Les personnes atteintes sont en majorité à la retraite avec un pouvoir d’achat limité. Le but de notre étude est d’évaluer le coût de la prise en charge du cancer de la prostate en milieu hospitalier. MATERIELS ET METHODES : Nous avons effectué une étude descriptive, médico-économique auprès des patients diagnostiqués de cancer de la prostate et hospitalisés à l’Hôpital Général Idrissa Pouye en 2018. RESULTATS : Un effectif de 105 patients était inclus. La moyenne d’âge était de 70 ans et la tranche d’âge la plus représentée était celle de 60 à 69 ans avec 48%. Une hospitalisation était nécessaire pour la majorité des patients. Le mode d’admission en hospitalisation était à 100% et le mode de sorti le plus fréquent était le retour à domicile à 93% avec une durée moyenne de séjour en hospitalisation de sept jours. Il y avait 62% de patients retraités, 8% de cultivateurs et 7% de commerçants. L’adénocarcinome de la prostate était le seul type histologique retrouvé. La forme avancée de cancer de la prostate avec des métastases était de 81% contre 16% de formes localisées et 3% et de formes localement avancées. Le traitement curatif était possible chez 16% de l’effectif contre 84% de cas de traitement palliatif. En effet, huit patients ont subi une prostatectomie radicale dont deux ayant une radio-hormonothérapie complémentaire et huit autres ont eu une radio-hormonothérapie seule. Le BAC médicamenteux était indiqué chez 63 patients, la pulpectomie testiculaire chez 14 autres. La RTUP était combiné à la pulpectomie chez un patient, suivi d’un traitement hormonal chez neuf patients et suivi d’une radio-hormonothérapie chez un patient. La chimio-hormonothérapie était effectuée chez un patient. Le coût des actes de diagnostic était estimé à 28.497.000 Fcfa, celui des indications thérapeutiques à 168.149.700 Fcfa et celui des actes de suivi estimé à 3.463.900 Fcfa. Le montant annuel de la prise en charge des 105 patients était de 200.110.600 Fcfa, soit un coût moyen estimé à environ 1.905.815 Fcfa par patient et par an. CONCLUSION : Les difficultés de la prise en charge du cancer de la prostate sont en partie liées à une inaccessibilité financière des patients. La réduction de la morbidité et de la mortalité de cette pathologie pourrait passer par la vulgarisation et la mise à disposition élargie des avantages de la CMU à toutes les catégories socio-professionnelles dans les EPS mais également par la recherche génétique et la biologie moléculaire pour une meilleure précision des approches thérapeutiques.

Published: July 2022

INTRODUCTION : Le but était d’évaluer les résultats oncologiques et la morbidité de la cystoprostatectomie totale (CPT). MATERIELS ET METHODES : Il s’agissait d’une étude rétrospective et descriptive, colligeant 19 patients sur une période allant de Septembre 2011 à Mai 2018, dans le service d'Urologie du CHU Aristide le Dantec. RESULTATS : La moyenne d'âge était de 58 ans avec des extrêmes de 32 et 77 ans. Le sex-ratio était de deux. La CPT avait consisté en une pelvectomie antérieure suivie d’une urétérostomie cutanée trans-iléale selon Bricker chez six femmes, en une cystoprostatectomie radicale associée à une urétérostomie cutanée trans-iléale selon Bricker chez 12 hommes et à une entérocystoplastie de remplacement selon Studer chez un homme. La morbidité postopératoire précoce consistait en un cas de suppuration pariétale (grade I), deux cas d'éviscération (grade IIIb), un cas de fistule digestive (grade IIIb), et un cas de péritonite urinaire (grade IIIb) secondaire à un lâchage de suture de l'anastomose urétéro-iléale chez le patient avec la néovessie de Studer. Ce patient était décédé en réanimation après la réfection chirurgicale de l'anastomose urétéro-iléale. Les complications tardives étaient un cas de pyélonéphrite aiguë, trois mois après la cystectomie et un cas d’occlusion intestinale aigüe. Deux patients atteints de carcinome urothélial avaient reçu une chimiothérapie adjuvante en utilisant le protocole M-VAC. Après un suivi moyen de 15 mois nous avons enregistré 13 décès, trois patients ont été perdus de vue et trois autres ont respectivement vécu 50, 68 et 80 mois après la cystectomie. La survie globale moyenne était de 15 mois (4,2 à 25,8 mois) avec une survie médiane de six mois. Le seul patient qui avait une néovessie selon Studer était décédé une semaine après cystectomie. La survie globale moyenne après pelvectomie précédente était de 17,2 mois et celle après cystoprostatectomie était 15,18 mois. CONCLUSION : Ce travail mettait en évidence le très mauvais pronostic des cancers de la vessie dans notre contexte lié au stade avancé des tumeurs au moment du diagnostic.

This paper articulates the implementation of new Public Procurement Act (No.15, 2015) in the Local Authorities (municipalities) in Namibia. This paper explores the concept of implementation with specific focus on how the decisions and plans based on the new procurement process were executed in practice within the Local Authorities in Namibia. Quantitative questionnaires were used and the numerical data obtained was analysed and presented in the form of numbers and statistics. The major findings of this paper show that the implementation process was not successful as the municipalities and its employees were not ready for the implementation of the new Public Procurement Act (No.15, 2015). The need for proper planning prior implementation was emphasized. It was found that key factors such as leadership and management aspects, communication, training of employees should be considered before implementation. This research adds great value as it addresses the need for a proper communication of the new system and leadership development to drive and manage the implementation process. The research also contributes to the body of existing knowledge as it alludes to people, as the most intangible components of readiness and when they are not ready, the results of implementation would be negative. Recommendations were made as outcomes of conclusions drawn from the data gathered during the research and are considered to have potential for improved and successful implementation of the new Public Procurement Act within the municipalities in Namibia.

A comprehensive evaluation of forest value based on carbon sequestration stock prediction
Authors: Chuai Ce , Zhao Jiahao , Wei Ping
Published: July 2022

The increasing greenhouse effect globally, the excessive deforestation of forests and the weakening of forest carbon storage capacity have brought about drastic changes in the global climate and posed a great threat to the biosphere. Therefore, the issue of "making efficient use of forest carbon storage capacity and diversified value of forests" has attracted our attention. To better analyze the problem of carbon sequestration and forest value and formulate a reasonable forest management plan, this article established two models: the "grey system model" and "BP neural network prediction model." The two models used China's forest inventory data in the past 40 years to predict that the average value of total forest carbon sequestration in China in a hundred years is 189.37×108t. Aiming at the problem of forest value evaluation, this article apply "grey correlation analysis method," "main component analysis model," and "fuzzy comprehensive evaluation model." This article considers the value of forests from two aspects: ecological value and economic value. In terms of ecological value: this article found that forests have various values such as "carbon sequestration, water conservation, soil conservation, and biodiversity maintenance"; Most forests have a "U-shaped transition period" in carbon sequestration capacity. "Tree age and tree composition structure" are the main factors affecting carbon sequestration capacity. In terms of economic value, this article found that "increasing the proportion of young trees and suitable for the production of forest products" is a good way to increase the economic value of forests. In addition, the research shows that there are obvious differences in the degree of carbon sequestration capacity and economic value of forests in different climate areas such as "subtropical zone, warm temperate zone, and middle temperate zone.".

Authors: Sun Yu , Wu Junhan , Li Gengluo
Published: July 2022

In order to evaluate the impact of Saihanba on the ecological environment, we selecte 11 factors from three aspects to build the Ecological Environment Health Index (EEHI) evaluation model; Next, We use a combined weighting method combining Hierarchical Analysis, Entropy Weighting method and Coefficient of Variation method to determine the weights of each indicator. Then the EEHI of the Seyhanba area from 1962 to 2020 was calculated using the TOPSIS; Finally, the ecological environment of the Seyhanba area was obtained with a yearly upward trend, and the effect of Seyhanba on the improvement of ecological environment was analyzed in three stages. In order to evaluate the impact of Saihanba on the anti-dust storm capacity in Beijing, we selected 9 indicators from three aspects to build the Sandstorm Resistance Ability (SRA) evaluation model in Beijing; Then, the Main Component Analysis method was used to calculate the SRA in Beijing over the years, and SRA was improved year by year. At the same time, we constructed the Sandstorm Index (SI) to indicate the annual severity of dust storms in Beijing; Finally, the relativity between SRA and SI was calculated using the Pearson Correlation Coefficient and find the correlation coefficient between these was -0.833, as a significant correlation. This show that the improvement of Saihanba's resistance to dust storms in Beijing effectively reduces the severity of dust storms in Beijing.

Published: July 2022

Under the background that central banks have successively issued green financial policies to deal with climate change, on November 8, 2021, the people's Bank of China officially announced the creation and launch of carbon emission reduction support tools to help achieve the "double carbon goal" as soon as possible. Support the development of key areas such as clean energy, energy conservation and environmental protection and carbon emission reduction technologies in a steady, orderly, accurate and direct manner, and leverage more social funds to promote carbon emission reduction. This structural monetary policy tool is different from the traditional monetary policy. It will drive the accurate delivery of basic currency through its special transmission mechanism; Stimulate the overall growth of green credit scale; Promote the adjustment of industrial structure; Help to further improve the relevant information disclosure and review mechanism. At the same time, as a long-term financial instrument, carbon emission reduction support tool still has great room for improvement in the future. It is expected to be continuously improved in supporting credit policies, issuing objects, supporting industries, disclosure mechanism and other aspects.

Published: July 2022

According to the FAO, we can see that the world's forests are large and growing. However, forest system also faces some problems. Challenged by ICM, we decided to build a model to balance carbon sequestration, forest products, biodiversity aspects, recreational uses, and cultural considerations, making improvements to existing forest management systems. Develop an optimal carbon sequestration model, and calculate how much CO2 the forest and its products can absorb. Identify a forest management plan that needs to be the most beneficial to society and to balance the various uses of the forest. We also write the specturm of the management plan, calculate the conditions under which the forest will not be deforested, and determine the transition points in the management plan.

Supply chain finance promotes the effective operation of all aspects of the supply chain and greatly promotes the development of the modern social economy. But because of its complexity, supply chain finance faces many risks, so it is vital to study and prevent supply chain finance risks. Aiming supply chain financial risks, this paper uses DEMATEL-AISM (Decision-making Laboratory Analysis-Confrontational Interpretation Structure Model) to analyze various factors affecting the development of supply chain finance and identify its transmission path. It is proposed to strengthen legal control, credit control, proficiency, supply chain management and supply chain operations, and find out and understand the things and links that are highly related to supply chain finance.; create a stable supply chain financial market environment and ensure market efficiency and other preventive measures. In this paper, the DEMATEL-AIM method is innovatively applied to identify and analyze supply chain financial risks, and the complex supply chain financial system is systematically analyzed. The relationship between indicators and the structure of the index system is found, which is helpful to identify the influencing factors of supply chain financial risks at all levels and their internal transmission mechanism. The preventive measures of supply chain financial risks are put forward, which provides ideas for effective prevention and treatment of supply chain financial risks and promotes the sustainable development of supply chain finance.

Published: July 2022

One of the objects of pride in the Islamic governance system is the waqf system. Its importance and positive impacts in societies are manifest clearly throughout different eras. Waqf plays significant role to promote working development and upgrading Islamic societies in various sectors; religious and worldly matters. The profound impact of waqf has stirred up Muslim and non-Muslim societies to study waqf and adopt it to serve their societies. This research seeks to consolidate fiqh awlawiyyah (preference) in waqf expenditures and its application. The research aims at demystifying definition of fiqh awlawiyyah in waqf expenditures and examining technicalities of its current applications. It presents practical idea for analogical methods of awlawiyyat. It is a qualitative research based on inductive and deductive analytical approach. It involves critical analysis and comparative approach for making preference. The researcher finds that it is important to guide waqf expenditures to ensure that it caters for basic needs in society and in line with social preferences and maqasid al-Shariah (objectives of Shariah). The researcher suggests practical accounting method for preferential analogy which is based on consideration of preference (al-tarijih) and maqasid al-Shariah.

Impact of Covid-19 Pandemic on the Financial Performance of the Banking Sector of Bangladesh
Authors: Kashem Mohammad Abul
Published: July 2022

Covid-19 pandemic has affected both real and nominal sectors of all countries in the world. The paper has examined the impact of this pandemic on the banking sector of Bangladesh. Using ratio and correlation analysis on 2019 and 2020 data some interesting findings are invented. Pandemic has incurred devastating and homogeneous impacts for all type of banks in Bangladesh. Profitability and efficiency have decreased sharply. The analysis shows that if the provision criteria had not been relaxed, the profit rate would have been decreased further. Negative growth of profitability and interest earning by the most banks are very glaring. Aggregate profit of the banking system has fallen about 4 percent. Further, evidence of investment scope shrinking is also manifested. Hence, sheer income rearrangement is also detected by the banks in pandemic situation. The loss caused by the decrease of interest earning was attempted to offset by the increase of fee based income. However, productivity is remained largely unchanged during the pandemic. Additionally, drastic fall of major balance sheet items in 2020 are also noticed. Banks were desperate to save themselves from the tsunami of losses by searching alternative sources of business too. Additionally, profit fall and international linkage of individual banks have very high association. The paper has very high stake particularly for crisis management of the banking system of developing countries where banks are suffering from the less variety of product and lending activities.

Authors: Benatia David , Gingras Samuel
Published: July 2022

The COVID-19 crisis has disrupted electricity systems worldwide. This article disentangles the effects of the demand reductions, fuel price devaluation, and increased forecast errors on New York’s day-ahead and real-time markets by combining machine learning and structural econometrics. From March 2020 to February 2021, statewide demand has decreased by 4.6 TWh (-3%) including 4 TWh (-8%) for New York City alone, and the day-ahead market has depreciated by $250 million (-6%). The real-time market has, however, appreciated by $15 million (+23%) because of abnormally large forecast errors which significantly undermined system efficiency.

In silico Prediction of C_4-related Genes by Finding Duplications Causing Pattern Deviation and Comparative Analysis of Phylogenetic Trees
Authors: Avdjieva Irena , Krachunov Milko , Vassilev Dimitar
Published: July 2022

This study is focused on the development of a pattern-finding method for analyzing evolutionary trees to predict genes that may be involved in C_4 photosynthesis. It relies on publicly available phylogenetic data which is processed with the authors' own Python scripts and opensource software. The pattern recognition in the topology of the trees is an essential part of the process and the result is then validated by comparing the expression levels of the selected candidates. The same approach can be applied in studying the evolution of other important traits just by changing the type of pattern.

Published: July 2022

The aim is to find a cost-effective method of identifying nutrient media producing identical plants with maximum performance in terms of the bioactive substances contained in them. An adaptation of QSAR is used. The "spatial structure of the chemical component" is replaced with "the multidimensional structure of the nutrient medium" or with the treated day schemes. For each process, a separate forecast is made. All nutrition media produced in silico are based on the ranges of phytonutrient hormones in biotechnological experiments. We found 43 theoretical combinations of media with more than 80% success under conditions of limited resources in the price range of [0-1,5] euro/liter. The obtained results can be used as: a theoretical guideline for determining the optimal nutrient media and combinations; to the study of other medicinal plants in order to establish effective biotechnological schemes for growth and rooting that are also cost-effective; using ANN, taking into account the species and the ecotype.
