Classify Glassy Antiques Based on the Chemical Components
Authors: Li Shangwen
Published: May 2023

As one sort of cultural relic, glassy antiques can effectively convey the historical information of a certain era and reveal the cultural exchanges in different regions as a symbol of foreign trade. However, due to long-term weathering and corrosion when buried in soil, the shape, color, and chemical components of a glassy antique can change considerably, and hence identifying it and recognizing its category is particularly difficult. Clustering is a popular technique of data analysis and data mining. K-means is one of the most popular data mining algorithms, as it is simple, scalable, and easy to modify in different contexts and fields of application. This paper uses k-means to find the clustering center showing the characteristics of the chemical components of different categories of glassy antiques. Then the particle swarm optimization algorithm (PSO) that offers a globalized detailed search methodology is utilized to improve the k-means clustering. The new result compared to the previous one of traditional k-means clusterin shows better classification capacity. Finally, it compares the results of k-means with that of PSO-k-means and analysis the advantages and disadvantages of PSO-k-means.

Authors: Li Chunjiang
Published: May 2023

With the development of deep learning and machine learning, more new methods have been produced in the economic and financial fields. When talking about machines, one thing that comes to people’s minds is what they can do with machines to solve problems that need machines. The people in the stock market always want to find ways to forecast the stock trend, the pattern of stock, and the stock value. Before the development of machine learning algorithms, stock market predictions could be made in limited ways, and those methods usually did not produce accurate predictions. However, machine learning algorithms changed the phenomenon and offered people novel ways to analyze the stock market. This paper will discuss three research in which authors have implemented machine learning algorithms into stock market analyses. From analyzing the research, this paper tries to investigate the extent of applying machine learning algorithms in the stock market and how the algorithms have helped investors make improvements in stock market analysis.

Almost no nation in the world is untouched by the global financial crisis after it starts, and the losses incurred can take a long time to fully recover from and even continue to have an impact on the world economy. This paper chooses the most significant 2008 financial crisis as the study object and conducts a thorough analysis of it based on the basis in fact of the 2008 financial crisis brought on by the global financial crisis in the United States. The 2008 financial crisis was the worst crisis the world economy has encountered since the Great Depression of the 2030s. The global credit market and capital market have received an unprecedented and violent impact, and the economic development of many countries around the world has stagnated or even declined. By studying the causes, consequences and corresponding adjustments and changes of the 2008 financial crisis, we can grasp the international economic environment more scientifically and analyze the trend of world economic development after the financial crisis from a more targeted perspective.
The Global Financial Crisis: Cause and Regulatory Response
Authors: Chen I Ning
Published: May 2023

This paper explores the connections between the 1930s Great Depression and the 2008 Financial Crisis. It also goes into great detail regarding the causation, consequences, and changes that surrounding the 2008 Great Recession. Particularly, the change in federal monetary policy during the early 2000s saw a spike in the amount of loans and mortgages. Accompanied by the positive expectations and aspirations of the investors, the housing market boomed. As a result, financial derivatives of asset-backed securities also flooded the market. In the end, this over-inflation of the housing market and its derived products created a housing bubble, which ultimately led to a catastrophic financial crisis when too high a leverage and inability of borrowers to pay back loans burst this overly-optimistic bubble. Upon the occurrence of this financial crisis, new policies were enacted and acts were set in place. Through interpreting the findings of 2022’s Nobel prize winning economists, individuals and groups alike are able to protect themselves from inevitable financial crises that take place in the future.

Authors: Xing Kewen
Published: May 2023

Starting from 2020, the world has been changed by the COVID-19 pandemic, a highly contagious virus that hit the world with many lives lost and the economy disrupted. This article analyzed Pfizer as the global leading pharmaceutical company, and a giant in biopharma, which demonstrated huge success in the pandemic with its famous COVID-19 vaccine “Comirnaty” and its oral anti-COVID drug, “Paxlovid”. The SWOT analysis helped to better understand Pfizer’s business position and its strength, weakness, opportunities, and threats. Thus we can have a more comprehensive view of Pfizer's business and its future potential. The analysis revealed that although Pfizer has taken some advantages during the pandemic with its bold moves and became the No.1 biopharma company in the world, it’s also facing many challenges, including its weak portfolio, slow R&D, and supply problems. However, we still believe Pfizer is striving to evolve into a more competitive biopharma leader with its continuous focus on science, bold moves, new culture to drive excellence, and new agile way of working.

Published: May 2023

In the context of an increasingly severe global climate, GDP cannot attribute natural resources to natural resources. However, the GGDP can reflect the interaction between the economy and the environment. Therefore, we first use the entropy weight method to establish a climate change index model to measure the global GGDP, and then use principal component analysis and multiple regression method to establish a model of the impact of GGDP on climate change and predict the trend of GGDP. Finally, the potential advantages and disadvantages of climate release after the use of GGDP are discussed.

Authors: Li Qiuyu , Liao Wenqing , Zhang Huangzhiyi
Published: May 2023

Regulatory inquiries are becoming more and more common these days. In a broad sense, corporate regulation is the act of auditing, evaluating and intervening in the compliance, authenticity and legal compliance of a company's objectives and results so that the corporate governance system operates healthily. Whether a company's being regulated has various impacts, positive or negative, on performance and share price is explored using the event study method, and the number of regulatory inquiries and questions asked of the company is described in detail using Duo Rui Pharmaceuticals as a case study, with a brief summary of the company's responses. This article analyses the impact of the company's performance after the IPO, starting with operating capacity, profitability and growth capacity, and comparing the data before and after the IPO. The comparison reveals that the overall operating capacity is slightly lower than before the IPO, and the company's profitability also shows a decline and a significant decline in growth capacity, indicating a reduction in the scale of the company's development. Regarding the correlation between regulatory enquiries and share price performance, the number of enquiries made to all GEM-listed companies under the registration system and the price suppression rate is statistically significant. It can be seen that the number of IPO enquiries directly impacts the price suppression rate of companies; the more IPO enquiries are made, the lower the price suppression rate.

A spare part is gradually produced and processed to form the final product for sale, the process of selling to consumers through online and offline means is called the SC. Its surface meaning is from merchants to consumers and from goods to income. As a daily necessity, household appliances have become one of indispensable elements in our life. With the development and innovation of information technology, there are numerous ways to buy home appliances. At present, the rapid development of science and technology has gradually promoted economic integration and economic globalization, and the economic competition of enterprises has gradually tended to SC competition. Due to the development of manufacturing, procurement and division of labor, the complex structure of the SC structure is increasing. In the meantime, the global impact of the epidemic in 2020 makes the SC of most household appliance enterprises face the risk of stagnation. In this social and economic context, information transmission risk and logistics operation risk have become the main reasons for the occurrence of enterprise financial risk. In order to survive, enterprises must seek new management techniques and methods to deal with the occurrence of risks. This paper will take the household appliance industry as an example, under the trend of SC localization, through systematic theoretical research to summarize and analyze the common supply risk factors and countermeasures of home appliance enterprises.

Authors: Xie Run
Published: May 2023

Concerns regarding publicly traded companies' R&D investment have long existed among academics domestically and overseas. Scholars have conducted much research on the R&D investment of enterprises from different angles. This study starts from the perspective of market expectation and loss aversion, taking the data of Chinese quoted companies from 2011 to 2020 as a sample and using the empirical analysis method to research the impact of changes in market value on quoted companies' innovation decisions. Robustness tests effectively corroborate the findings of the study, which found a substantial positive association between changes in the market value of listed businesses and the degree of innovation investment. Additionally, this study conducts a group regression test on the R&D investment growth rate (RDI) of state-owned companies (SOEs) and non-state-owned firms using the two explanatory variables of total market value growth rate (RDI) and Tobin's Q value (Tobin's Q) (NSOEs). It is discovered that NSOEs are more vulnerable to market capitalization change than SOEs are, and the listed businesses' intentions to innovate are influenced by changes in market capitalization through the loss aversion mechanism.

Authors: Li Yuancheng
Published: May 2023

Apple is one of the most successful companies in the electronic products industry. Its success is indispensable to its effective marketing strategies. This paper focuses on analyzing the psychological trick it used in its marketing strategy, mainly the endowment effect and status quo bias. It investigates how Apple uses these cognitive biases to attract newcomers to use its products and how it cultivates loyal consumers. The endowment effect refers to a circumstance to which an individual attaches higher importance to the object that they own than the same object they do not own. Apple's showroom enables consumers to play around with its products which gives the consumer a sense of ownership that make consumers become more painful to relinquish its product. Status quo bias describes the circumstance where people prefer to maintain the current state and are reluctant to change. It helps Apple to keep the existing consumers around, which also gives Apple more incentive to constantly upgrade its products and induce consumers to buy. Lastly, this paper will discuss what consumers could do to avoid being “manipulated” by Apple’s marketing strategy and falling into the consumption trap.

Published: May 2023

Introducción: Uno de los principales problemas que se afrontan en las clases de Educación Física es la baja motivación de los estudiantes para realizar los ejercicios indicados por el docente. El objetivo del artículo es presentar el proceso que se desarrolló y posteriormente presentar la implementación de un conjunto de videos educativos para acompañar los cursos de Educación Física en una institución pública ubicada en un municipio del nororiente de Colombia. Por otro lado, la implementación de metodologías pedagógicas mediadas por las tecnologías de la información y de la comunicación (TIC) ha demostrado resultados positivos para mejorar la motivación de los estudiantes en diversas áreas del conocimiento. Metodología: Así pues, este trabajo presenta los resultados de un diseño experimental, en que se utilizaron una serie de videos educativos para mejorar la motivación en la clase de Educación Física. En el estudio, participaron 31 estudiantes entre las edades de 16 y los 18 años (M = 16,48, DE = 0,67), en el grupo de control 16 estudiantes (7 hombres y 19 mujeres) y en el grupo experimental 15 estudiantes (9 hombres y 6 mujeres). Resultados y discusión: Los resultados indican que al usar los videos mejoró significativamente la motivación de los estudiantes con la que realizaron los respectivos ejercicios. Conclusiones: Estos resultados son prometedores y representan un aliciente para seguir replicando este tipo de actividades que enriquecen las clases de Educación Física.

Published: May 2023

SQL er et vidt udbredt værktøj inden for databaser. For os, der arbejder med geografiske data, er databaser typisk også en del af vores arbejdsområde. Og for os findes der udvidelser eller tilpasninger til SQL, som gør det muligt at arbejde med de geografiske aspekter af data.
I denne artikel vil jeg give en række eksempler på geografiske SQL-forespørgsler i MapInfo Pro og i PostgreSQL med PostGIS.

Authors: Fernando Sonny Rae I , Villanueva Louie B
Published: May 2023

Playing traditional games are a significant milestone in the lives of every child which served as their amusements. Albeit the presence of technology games nowadays, the twenty respondents who were purposively selected are still very much familiar with most of the traditional Ilocano games. Thus, this study accessed the gender roles behind some Ilocano Traditional Games. It made-use of the ethnographic approach method as research design. Based from the findings, it surfaced that there are traditional Ilocano games that were designed solely for males, as well as for females and for both sexes. These games helped them to better understand their role in the society especially in accordance to their genders. Respondents were able to understand on how a man and woman should do in a real family setting, awareness on gender equality, and socialization to other people. Through games, they were able to shape and strengthen their gender identities as they are at the present. Also, they could identify their weaknesses and strengths as a woman or man. To gain clarifications on gender concepts and eventually develop full awareness of gender role on Ilinano Traditional games, they must develop gender-sensitive behaviors, which is a must in a responsive environment.
The Modern Filipina Archetypes and Ambiguities in the Wildflower Teleserye vis-à-vis Filipinos’ Sensibilities
Authors: Ocampo Darrel M
Published: May 2023

The article is a discourse analysis of the Wildflower telerserye, exploring the themes and portrayals of the main character and the ambiguities projected by her characterization. The research’s objective revolves around the details that upon the attempt of the telersye to flaunt the modern archetypes of a Filipina, a strong and empowered woman who liberates under the yoke of patriarchal hegemony, her actions and ways were deemed crucial and subjected to great scrutiny. The researcher also dealt with how these portrayals affect and reflect the Filipinos’ way of thinking and sense of morality. Two major literary theories were used to underscore the article’s crucial points. To show how the woman portrayals in teleserye try to subvert the idea and configuration of patriarchy, Feminism (Helene Cixous) was used. Meanwhile, Deconstructionism (Jacques Derrida) was employed to show that in the attempt of the teleserye to empower the woman lead character, remove her from her marginalized and stereotypical views, and liberate her from the yoke of patriarchal hegemony, the result was otherwise. Based on these analyses, a synthesis of Filipinos’ sensibilities on how it affects and reflects their ways of thinking was crafted.

Stroke in children is a rare but devastating disease. Although endovascular treatment has been reported to be safe and effective in the treatment of stroke with large vessel occlusion in this population, there are still limitations and controversies. In this case report, we describe a 12-month-old girl who was admitted to the hospital with acute onset of left-sided hemiplegia and confusion, which turned out to be due to a large infarct in the right middle cerebral artery territory, possibly caused by dissection of the right cervical internal carotid artery. Aspiration thrombectomy was successfully performed, and the patient was able to walk a few steps and raise her left upper extremity at the 12-month follow-up. The aspiration-only technique in thrombectomy may be safe and technically feasible to treat acute ischemic stroke with large vessel occlusion in children as young as 12 months, although large-volume prospective studies are needed.
