Authors: Turanboyev Boburjon Qodirjon o'g'li  , Rajabboyev Botirjon Odil o’g’li
Published: March 2023

The need for stock market is rising in the modern day. Particularly, there is growing interest in companies with high share prices. However, the danger also rises as the interest does. There are several reasons for this. In other words, inflation is one of the largest risk concerns. Inflation control is a national issue, not just a business issue. Research on this subject was done by scientists including Thomas C. Chiang, Amal Essayem Sakir, Gormus Murat Guven, and Pierlauro Lopez. However, they haven't done enough study on how to predict inflation and how much it affects the stock market. The stock market, inflation, and the predictability of stock market returns are all topics that are clarified in this article.

Advanced detection of coronary artery disease with multimodality imaging
Authors:   , Driessen Roel Sebastiaan
Published: March 2023

Because coronary artery disease (CAD) remains a leading cause of global morbidity and mortality, a careful diagnostic workup of patients with suspected CAD continues to be of utmost importance. Invasive coronary angiography (ICA) is currently the reference standard for diagnosing obstructive CAD, especially in conjunction with invasive functional tests. However, because of the potential risks and costs related to ICA, current guidelines advocate to use non-invasive imaging as an initial test in patients with suspected CAD. Although, or perhaps partially because of, an ever increasing array of diagnostic tools are available for contemporary cardiologists, the diagnostic workup remains challenging. Therefore, this thesis investigates the diagnostic value of multiple established and novel imaging modalities when compared with invasive reference measurements. Furthermore, additional non-invasive imaging features are tested for a potential incremental diagnostic and prognostic value. Finally, this thesis explores the complex relationship between coronary stenosis, plaque morphology and flow in a non-invasive as well as invasive fashion.
Coming to grips with diverse voices in participatory heritage initiatives
Authors:   , Zheng Nana
Published: March 2023

Community participation is increasingly advocated as a promising approach to cultural heritage management. One of the main justifications for doing so is to challenge the authorized heritage discourse and further multivocality. However, regarding the approach of “community participation”, many issues are yet to be addressed. This project tackles one of the main issues faced by participatory heritage initiatives. That is, with the presence of diverse voices about heritage in a so-called community, how does the community deal with the multivocal reality? This project explores this question by drawing on various examples from three Italian communities - Mesagne and Latiano from the southern Italian region of Apulia, and the neighbourhood of Testaccio in the historic centre of Rome.
A Study on the Role of Compensation Incentives and Equity Incentives in Technology-based Enterprises
Authors: Yang Congwen
Published: March 2023

Technology-based enterprises, driven by innovation, have flourished in the economic market in recent years. For technology-based enterprises, how to effectively motivate employees to unleash their innovation drive and thus improve corporate performance is a key focus of management in technology-based enterprises. Pay incentives and equity incentives have been widely used in enterprise personnel management in recent years, and previous scholars generally believe that these two approaches can be more effective in motivating employees to innovate and establish a sense of ownership. In order to better study the shortcomings of salary and equity incentives in innovative companies and the strategies to solve them, this paper summarizes the relevant studies and uses Huawei and Hikvision, which have excellent incentive policies, as examples, to find and point out that the level of managerial shareholding and salary level are the criteria for incentives and should be limited to a reasonable range. Secondly, different incentive methods should be used at different stages to optimize the incentive effect.

A Study on the Applicability of Black-Scholes Option Pricing Model in Chinese Stock Index Option Market
Authors: Wang Shihan
Published: March 2023

Compared with the developed countries, Chinese stock index option market developed late and accumulated less historical data. At the same time, it has the characteristics that many developed countries' stock option markets do not have. Black-Scholes Model is an important model in the field of option pricing. It is not enough for a financial model to be reasonable in theory, but it needs to be tested by the actual market. Therefore, based on the main transaction data of the CSI 300 stock index option contracts from 2010 to 2020, this paper analyzes the compliance of the CSI 300 stock index option market to the basic assumptions of the B-S option pricing model, the main parameters of the CSI 300 stock index options in the B-S option pricing model, and the fitting degree of the B-S model's prediction and actual prices. The result shows that there is a certain deviation between the pricing conclusions of the B-S model and the actual option prices. This paper analyzes the reasons for the deviation from many aspects, and puts forward the corresponding improvement strategies that the users of the model should adopt, so as to improve the applicability of the B-S option pricing model in Chinese stock index option market.
Impact of Green Credit on Industrial Structure in China
Authors: Zhang Lu
Published: March 2023

Since the reformation and opening up, the conflict between domestic economic development and environmental pollution has become increasingly obvious, and the structure of industry needs to be adjusted urgently. Based on the strategic background of sustainable development, green credit policy has been proposed to balance the relationship between economic development and environmental protection. Green credit adopts a differentiated credit strategy for highly polluting industries and green and energy-saving industries to support the development of green and environmental industries, forcing highly polluting and high-emission industries to upgrade their technological innovation and reduce energy consumption and pollution emissions. In the demand for green economy, China's green credit has become the main driving force to achieve high-quality development such as ecological, circular and low-carbon development of industries, and green credit has a positive effect on the upgrading of industrial structure. In the process of implementing green credit in China, there are still problems such as time lag in the improvement of industrial efficiency and obvious differences in the promotion effect in different regions, which affect the effect of green credit on the optimization and upgrading of industrial structure. It is recommended to focus green policies on the government and banking financial institutions, increase the government's green financial support, and continuously improve the green credit system of banks.

Published: March 2023

The escalation of the Russian-Ukrainian war not only strengthened the geopolitical turmoil, but also affected the global capital market. This paper collects information about the S&P 500 and other indexes; Comparison of yields on 2-year, 5-year and 10-year U.S. treasury bonds and VIX index; CPI, gold price, gold inventory and gold futures price, etc.; Crude oil production, crude oil prices and inventories, crude oil futures prices and other data before and after the war (February 23, 2021 to February 23 and 2022, February 24, 2022 to now). It aims to study the objective impact of the Russian-Ukrainian war on the US capital market and asset price trend. It is found that the volatility of the stock index of U.S. stocks increased at the beginning of the war, and the overall U-shaped; The VIX index also increased, meaning investors wanted to increase purchases of assets with safe-haven properties such as U.S. Treasuries and gold; The short-term increase in demand for gold futures and crude oil futures will increase the price of gold and crude oil, but will gradually return to the normal level as the war progresses.
Stock Selection Strategy and Model Test in A-share Market
Authors: Feng Xuzhou , Wang Mingyu , Wang Ziwen , Xu Yue
Published: March 2023

Fama and French put forward the famous three-factor model in 1992, book-to-market ratio and market capitalization are added to the market combination factor of CAPM single factor mode to explain the value effect and scale effect, and then proposed the five-factor model in 2015. Based on this background, this paper wants to do regression experiments on these models in A-shares to validate their explanatory ability on stock returns. All the data include the actual data of all non-ST stocks in the A-share market from January 2006 to December 2019, the book-to-market ratio data of all listed companies in the A-share market (non-ST), the return on equity data of all listed companies in the A-share market (non-ST), and the change rate of total assets of all listed companies in the A-share market (non-ST). Using the three-factor model and five-factor model to explain China's A-share market, it is found that these two-factor models have a relatively poor ability to explain the A-share market, and the R-square fitting fluctuates greatly. The three-factor interpretation is better, the R-square fitting has a small fluctuation, and the five-factor R-square fitting has the smallest fluctuation and the largest fit. CAPM single factor model has been proposed for a long time, but the factor model still can explain, and it is still very good. This is because alpha is almost always insignificant. However, the fitting fluctuates greatly and the explanatory power is inferior to Fama-French three-factor model and the Fama-French five-factor model.
Research on Asset Division and Evaluation Methods

Published: March 2023

With the deepening of globalization in the world, the economies of various countries are also pouring into the international financial market. Against this background, China's securities market is also coming into the opening. China's inclusion in MSCI China Index has made it more attractive for global funds. However, since its inception in the early 1990s, China's stock market has been viewed as highly speculative always, which will interfere with investors' investment behavior. To allocate funds reasonably in the A-share market better, investors need to classify assets and formulate different stock selection strategies for different types of assets. Therefore, this topic is focused on how to select stock and how to evaluate assets from different views. We analyze different stock selection strategies through accounting, mutual funds managers, stock market and traditional views with various calculating methods. Through summarizing several related research, we found that the effectiveness of the Fama-French three-factors model in the Chinese stock market is poor and the investors' sentiment and the number of retailers both make a difference in investors' stock selection strategies. To evaluate assets, we discussed the evaluation of tangible and intangible assets separately. We conclude that it's easy to process data for intangible assets and this calculation method will perform better in the Chinese future market.
Construction and Analysis of Individual Stock Sentiment Anomalies in the A-share Market
Authors: Yin Bochen
Published: March 2023

Behavioral finance heralds investor sentiment as an anomaly in traditional asset pricing models, and the financing and financing business is an important indicator of individual stock sentiment. In this paper, this paper try to use the growth rate of monthly balance of financing and financing securities as a factor SEN to explain stock returns in the context of Chinese A-share market. This paper finds that market capitalization and SEN have a significant inverse monotonicity, and their information crosses to a large extent to make SEN redundant. This paper argues that the reason for the redundancy of SEN due to market capitalization is that the A-share stock market has set a high margin for financing and financing business, which leads to a weaker liquidity of market transactions and limits the investment choices of rational investors to stocks with relatively small market capitalization. Based on the conclusion, this paper suggests that small investors adopt a strategy of going long on small-cap stocks and short on large-cap stocks.

Authors: Lei Ziyao
Published: March 2023

This paper aims to discuss optimal portfolio construction with assets among luxury goods, new energy, web 3.0, and gold industries, with the hope of providing insights into the investigation of the relationships between those industries and their feasibility in the process of portfolio optimization. Based on accessible data from Yahoo Finance, this paper first discusses mean-variance analysis with a focus on the return data of the chosen assets, then utilizes Fama-French three factor model to run a portfolio optimization among those assets with core indexes being the maximization of Sharpe Ratio and the minimization of variance. As a result, two portfolios with different weights assigned to each asset are generated and they could be a good indication of the relationships between the discussed industries and their connections under investment scenario, and therefore may provide valuable information to the related financial market investors.
Application of mean-variance modal in four industries
Authors: Yue Zexin
Published: March 2023

Portfolio optimization is highly valued and used by many people in the financial field. This paper analyzes the asset portfolio allocation of different industries, namely, transportation industry, software industry, semiconductor industry, and insurance industry. This paper selected four representative assets from these four industries, and then used the mean-variance combination model to analyze asset allocation and forecast the return on investment. In order to find the optimal proportion of investment portfolio in these four industries. The results show that "MMC" has the largest weight proportion in the combination of least squares and the maximum Sharpe ratio combination's "MSFT" weight percentage is the highest, while "UPS" has the smallest weight proportion in the combination of least squares and maximum Sharpe ratio. Therefore, in these four industries, the mean-variance model predicts that the insurance industry and software industry can get the maximum rate of return, while the cosmetics and nursing industry cannot get the maximum rate of return.

Authors: Zhai Hengyong , Yang Bin , Fu Yiwei , Zhang Dongli , Li Yujiang , Huang Junxing
Published: March 2023

We aimed to evaluate the effects of somatostatin combined with early hemoperfusion on inflammatory and stress responses during acute pan-creatitis (AP) treatment.A total of 159 AP patients treated from September 2016 to January 2020 were randomly divided into three groups A-C (n=53). In addition to routine treatment, groups A-C were additionally given somatostatin, early hemoperfusion, and somatostatin combined with early hemoperfusion, re-spectively. Their inflammatory factors, stress response, intestinal mucosal bar-rier, hemorheological indices, recovery time, length of stay, clinical efficacy, and adverse reactions were compared. The levels of serum interleukin-10 (IL -10), catalase and glutathione peroxidase rose in the three groups after ten days of treatment, compared with values before treatment, being the highest rise in group C. The levels of IL -18, tumor necrosis factor-α, soluble intercellular adhe-sion molecule-1, procalcitonin, high mobility group protein B1, lipid hydrogen peroxide, advanced oxidation protein products, epinephrine, cortisol, D-lactic acid, diamine oxidase, and endotoxin decreased after ten days of treatment compared with those before treatment, which were lowest in group C (P<0.05). After ten days of treatment, the levels of hemorheological indices were signifi-cantly lower than those before treatment (P<0.05). Compared with groups A and B, group C had a shorter recovery time of urine amylase, bowel sound and passing gas, remission time of abdominal pain, length of stay, and a higher to-tal response rate (P<0.05).During AP treatment, somatostatin combined with early hemoperfusion effectively relieved inflammatory and stress responses, protected the intestinal mucosal barrier function and improved the hemorheol-ogy, thereby promoting the recovery and benefiting the prognosis of patients.

Authors: Herman Achmad
Published: March 2023

This study aims to identify the effectiveness of using social media for a regional election campaign in Central Sulawesi. This study used a qualitative method. The informants for this study were campaign teams and political actors involved in the use of social media in the 2018 regional election in Central Sulawesi. This study also involved people or communities who felt the effects of social media in the regional elections. Data were collected through observations, in-depth interviews, and documentation. In addition to in-depth interviews, spontaneous interviews were also conducted. Data were analyzed using an interactive approach covering data reduction, data presentation, and drawing conclusions. The results of the study showed some benefits of social media in regional head elections in Central Sulawesi, but also weaknesses such as the widespread hoax news and hate speeches in social media. Technological developments through social media in the implementation of regional elections have become the center of attention which facilitates and make the Election Supervisory Agency work harder due to the hoax news and hate speeches by the campaign team of each candidate in Central Sulawesi. In general, social media makes it easier for the campaign team to implement political communication but during the election process, there are frictions caused by hoax news and hate speech from each campaign team.

Authors: Hove Netsai , Chinamasa Emmanuel
Published: March 2023

This study influenced by the Technology adoption theory, explored the prevalence of calculators in Ekudibeng circuit mathematics classrooms in South Africa. Pragmatism guided assessment of technology adoption by allowing application of both quantitative and qualitative data analysis to portray reality. A sequential design of document analysis, a survey, lesson observations, focus group discussions and in-depth interviews was used. Empirical data was collected from a purposive sample of 154 participants, composed of 41 teachers of mathematics and 113 learners from grade 8 to 12 in Ekurhuleni South district secondary schools. A sample of 26 teachers’ schemes and mathematics school syllabuses was analysed. The study found (71%) prevalence for calculator use in both public and private schools mathematics classrooms. A hypothesis test at 5% level of significance confirmed an association between gender and calculator use preference. Although all teachers reported willing to use the calculator, 54 (35%) reported, not possessing a personal calculator. Study found five calculator models in use. The majority used the SHARP model. National examinations disallowed the graphic FX-CG50 because of its perceived complexity. Calculators were used for computation of ( r2) regression coefficient correlation and evaluation for logarithms and trigonometry ratios for transformation functions such f(x) = 2Sin θ. Factors retarding calculator adoption include; lack of financial resources for high density public school learners, limited teacher commitment for calculator use and low teacher technical knowhow of using calculator for instruction.. National examinations not emphasising use of calculators, mathematics text books do not show how calculators can be used for instruction. Study recommends use of a single calculator model as a district policy. Authoring of a teachers’ handbook for the use of calculators for instruction is called for. Mathematics teachers’ staff development workshop on the application of calculators is long overdue.
DETERMINANTS OF RURAL SECONDARY SCHOOL DROP-OUT IN ZIMBABWE: A CASE OF RUSHINGA DISTRICT, MASHONALAND CENTRAL PROVINCE
Authors: Mangwiro Temba , Chinamasa Emmanuel
Published: March 2023

The study explored determinants for school dropouts as a basis for management strategies to reduce it in rural schools. Study was motivated by the prevalence of pupils dropping out of rural secondary schools in Rushinga District, Mashonaland Central Province. School dropouts are a direct attack on the education for all policy in Zimbabwe. This study was guided by pragmatism research philosophy poised at understanding appropriate rural school human related variables which can be analyzed using mixed methods to facilitate triangulation of survey, document analysis and focus group discussions. School dropout problem required data collection from purposive samples of schools, parents and learners. The inclusion criterion was their being rich sources, being available and willing to participate in the study. Data was gathered through focus group discussions contributed by 193 parents who attended school development meetings in nine (9) secondary schools. Seventy-two (72) learners from these schools responded to a selfadministered questionnaire. The study found a (2%) learner dropout prevalence rate in Rushinga. There is an association between gender and inclination to drop out. Girls were more inclined to drop out of school than boys. Factors motivating learner drop out included; low ability to handle academic curriculum, perceived low economic utility value of Zimbabwe’s education, perceived happiness in marriages and readily available cash for gold panning. The study recommends a decentralized curriculum developing skills for the utilization of local economic resources. For example, in rushing, a curriculum focused on mining and environmental conservation would be appropriate. Learners need parental support discouraging them from early marriages. Awareness campaigns against early marriages can be done in schools, churches and any social gatherings to educate both children and adults. Teachers are called upon to apply a variety of teaching methods to motivate pupils and raise their performance. The Ministry of Primary and Secondary Education facilitate low cost boarding facilities.

Authors: Maidaani Ziyambi , Gibson Ncube , Jacob Mapara
Published: March 2023

The purpose of this study was to establish university students’ foreign language preferences. It was motivated by the observation that, in Zimbabwe learners’ foreign language preferences are not included in the curriculum. This study was guided by the pragmatist philosophy which sought what works in a given context. The research design was a linear combination of document analysis, survey and focus group discussions. Data was collected from a stratified sample of 279 adult learners at a university of technology in Zimbabwe. The study found that, Zimbabwe school curriculum is limited by the foreign language policy to offer the following foreign languages: English, French, Portuguese and Chinese mandarin. Learners’ foreign language preferences include Japanese and Chinese to facilitate trade and commerce. Zimbabwe imports computers and vehicles under the “Look East policy.” These technical appliances bring with them repair and maintenance manuals which are in Japanese or Chinese. Consumers who are illiterate in such foreign languages operate and repair them on a trial and error and trial and success basis. The utility value of foreign goods dictates the need for foreign languages in the school curriculum from primary school. Schools limit their foreign languages because there is not compulsory policy. They have no teachers for other foreign languages besides English. The study encourages foreign bilateral relations for the promotion of language teachers’ from Zimbabwe to learn foreign languages and how to teach it within the appropriate context. Foreign embassies canthe teaching of foreign languages by supplying videos which can be played and discussed in the context of the foreign culture. The few lecturers and teachers of foreign languages can be sponsored to write or translate stories from Zimbabwe’s context into any foreign language that they are competent in to enhance the utility value for foreign languages in Zimbabwe.

Capability in government in India :
Authors: Smith RFI
Published: March 2023

This paper examines capabilities in government in India. Possibilities for improvement have implications for all levels of government. The intention of many proposals is twofold: to help citizens get what they need from officialdom and to enable different levels of governments to relate more effectively to diverse communities and to each other. The paper explores four topics: ways of thinking about capability in government; how strategies for politics can overshadow directions in government; how improving the management of relations between different levels of government can benefit all; and how opportunities for improving civil service capabilities, at the central, state, and local levels need political as well as internal leadership.

The COVID-19 pandemic is an outbreak of an infectious disease originating from the SARS-Cov-2 virus. As the virus grows, it causes various problems in various areas of life in society. The impact felt was so real with the cases of high death rates, unstable economy and other problems. The government, which has an obligation to make people's welfare take various policies to overcome this problem. From policy making, surely, it intersects with state finances which will ultimately affect the financial performance of the government itself. The purpose of this research is to determine the impact of the COVID-19 pandemic on the financial performance of local governments. The method used in writing this article is a qualitative method in the form of a literature review. The data obtained comes from secondary data, namely in the form of indirect retrieval via Google Scholar, Sinta and several articles that support the concept of the theme ranging from 2017-2022. The results of this study show that there have been changes in Indonesia's economic quarter and the regional budget experienced a minus number. Even so, the influence of the Covid-19 pandemic did not have a significant impact on the financial performance of local governments in several regions in Indonesia.

Goat milk, a highly nutritious product is widely used in cheese making. In order to properly select suitable milk samples for production, fifty-five samples of raw goat’s milk were collected from eight farms in the North-West of Morocco to analyze their counts of various mesophilic bacteria and determining the physicochemical characteristics during different seasons of the year. Lactic acid bacteria (LAB) were isolated, identified, and screened for several technological properties. Overall mean values for mesophilic aerobic flora were above 7.10 log cfu/mL in spring and 5.80 log cfu/mL during winter with a statistically significant difference found between all the microorganisms except for coagulase-positive staphylococci. The physical and chemical composition tests showed higher values for fat (4.9±1.01%), dry matter (13.98±0.95%), ash (1.3±0.12%), lactose (3.1±0.65 g/L), and protein (4.6±1.03 g/L) during the winter season which could be of great interest for cheese production. fatty acids (FA) composition mainly consisted of saturated fatty acids (SFA) in both seasons. Lactococci isolates were the most acidifying (pH6h=4.35–pH24h=4.08) while Lactobacillus paracasei produced the highest proteolytic activity (66.93±2.63 mgTyr.L-1) and diacetyl-acetoin (54.83±0.46 mg diacetyl/L). None of the tested isolates were lipolytic, however, several lactobacilli and lactococci exhibited a high salt tolerance and exopolysaccharide (EPS) production. Lactobacillus plantarum exhibited the highest lysis rate (67.34±1.76%) while the antibacterial profile ranged between 10.5±0.137 and 22.9±0.23 mm. The obtained results highlight the importance of Moroccan goat milk as a valuable component for cheese making due to its rich fat and protein contents alongside its abundance in LABs with biotechnological properties.

The imidacloprid (IMID) and cypermethrin (CYP) pesticides are known to have neurotoxic effects and negative brain developmental consequences when used separately, but little is known about the consequences of using them as a mixture. That could be passed down from one generation to the next. In this context, we were interested in studying the effect of oral exposure of female rats during gestation and throughout the lactational period to real doses of IMID (1.2 mg/kg) and CYP (6.7 mg/kg) either alone or in a mixture on behavior and mitochondrial redox status. The first and second generation pups were followed from birth to juvenile age using a series of tests to assess reflex, coordination and general motor function, including surface righting, cliff aversion, negative geotaxis and the muscle strength test. At PND 21, cholinergic function, oxidative stress and mitochondrial integrity were assessed in the striatum and hippocampus. Our results showed that IMID and CYP, alone or in combination, induced decreased body weight gain, impaired neurobehavioral performance, and AchE inhibition. Oxidative stress markers including GSH level and SOD, CAT, GST and GPx activities showed a significant decrease. While, lipid peroxidation which was assessed by MDA assay, cytosolic calcium level, swelling and mitochondrial permeability recorded a significant increase. In conclusion, the disruption of mitochondrial redox homeostasis and the presence of neurobehavioral disorders even in the offspring of the F2 generation suggests that independent and combined exposure to IMID and CYP during a critical period of development has irreversible effects; long-lasting and persistent.
