Constructing Trading Strategies by Applying and Adapting Q-factor Model in the Australian Market
Authors: Zhang Yuhao
Published: June 2024

The Q-factor model is a quantitative pricing model similar to the Fama-French multi-factor model, which is an investment approach using investment (IA) and profitability (ROE) as the significant factors. This paper collects historical data (1987~2022) from Australian stocks and constructs long-short portfolios to investigate the effectiveness of applying this model in the Australian market. Net returns will be validated by Carhart regression. Finally, the optimal factor portfolios and trading strategies will be tested for factor substitution based on cumulative return trends and risk-return metrics. Overall, both the Q-factor model and the augmented Q-factor effectively analyzed investments in the Australian market. The difference between theoretical and practical-based long-short is mainly due to the abnormal ranking performance of individual factors, especially during the COVID-19 pandemic. In most cases, strategies based on actual data sorting generate better risk-return outcomes than theory-based approaches, suggesting that the models must be continually adapted to suit Australia's unique economic and market conditions.

Analysis of the Composition and Characteristics of Dark Matter
Authors: Zhu Qingjingfei
Published: June 2024

Today, astronomers use different methods to study the structure and evolution of the universe. However, they will all be affected by other factors such as light or electromagnetic radiation. It is impossible to accurately observe the structure of the universe in the distant past. To find objects that fit the criteria, the existence of dark matter was assumed. It only has a gravitational effect and will be less affected. The composition and characteristics of dark matter are important research foundations. In this paper, the Cosmic Microwave Background (CMB) and power spectrum are used to study the status of dark matter in the universe. The search found Weakly Interacting Massive Particles (WIMPs) to be a candidate in the dark matter component. The three types of dark matter are cold dark matter, warm dark matter, and hot dark matter. Comparing their respective characteristics, it is concluded that cold dark matter (CDM) is the condition for observing large-scale structures. The result is that dark matter constitutes the second largest component of the universe. WIMPs are more suitable candidates than Neutrinos. CDM is best suited for studying large-scale structures over time. Eventually, it will be discovered that dark matter has strong stability, which will help astronomers find the process of universe evolution. Dark matter is also an important player that is best used to study the structure and evolution of the universe.

The Role of Emotional Intelligence of Coaches and its Impact on Coaching Skills in Basketball
Authors: Shi Guojian , Chang Liza
Published: June 2024

This research investigated the evaluation of basketball players in terms of their coaches' emotional intelligence and coaching abilities, as well as the correlation between coaches' emotional and social intelligence and their coaching skills. The study investigated how basketball coaches adjusted their teaching methodologies and tactics to cater to the emotional requirements and individual temperaments of diverse players. The results indicated that basketball players regularly evaluated their coaches well about emotional intelligence aspects, such as self-awareness, self-control, social sensitivity, and interpersonal skills. Coaches were evaluated well in several categories of coaching skills, including physical endurance, patience, strategic thinking, networking, leadership, meticulousness, empathy, observation, flexibility, and CPR. Nevertheless, the correlation studies revealed only feeble and statistically inconsequential connections between coaches' emotional and social intelligence and their coaching abilities. This implies that there may not be a clear correlation between emotional intelligence and specialized coaching abilities in these particular domains. The coaches' ideas for adapting to players' emotional needs and personalities include player evaluations, customized motivator techniques, adaptations to practice drills, and the cultivation of team dynamics. Coaches stressed the need to comprehend the distinct attributes and preferences of each athlete to provide a nurturing and efficient coaching atmosphere.
Gendered Manifestations of Para-social Interactions between Female Fans and Male Idols in China
Authors: Li Min
Published: June 2024

This study aims to reveal the gendered manifestations of para-social interactions between female fans and male idols in social media platforms in China, to clarify in which aspects they serve to reinforce the traditional gender order and in which aspects they deviate from the traditional gender norms, with a view to contributing positively to the optimisation of the relationship between female fans and male idols. Digital ethnography approach is used in this work, based on the Sina Weibo platform, to conduct a 15-day online observational study of seven Chinese male idols, namely Ma Jiaqi, Liu Yaowen, Song Yaxuan, Deng Jiaxin, Tang Yuzhe, Zhu Yilong, and Yang Yang, as well as their female fans. The blind consumption and unpaid labour of Chinese female fans for their male idols, as well as the polygamous "courtly love" relationship between the two, reaffirm and reinforce the traditional gender order. At the same time, the transformation of Chinese female fans from erotic objects to erotic subjects, their love for multiple male idols, their concern for ambiguous relationships between male idols, and their adherence to self-principle and subjectivity have rebelled against and even subverted traditional gender norms. However, the power to counteract the traditional gender order is not strong enough, and is still limited by factors such as exclusivity within the fan community, heterosexual hegemony, and idolatry that is as crazy and irrational as religious beliefs.

Impact of Estrogen in Menstrual Cycle on Food Intake, Appetite, Energy Expenditure
Authors: Li Sijia
Published: June 2024

Women have more difficulty with weight management compared to men, primarily because of sex variations in appetite and energy expenditure (EE) control caused by estrogen. In women, estrogen changes with the menstrual cycle and affects food intake (FI), appetite and EE. Research shows that in the luteal phase (LP), women's FI and appetite are significantly higher, while in the follicular phase (FP), FI and appetite are lower, and FI is the lowest in the FP. EE also increases significantly during the LP. In addition, polycystic ovary syndrome (PCOS) patients have higher FI and appetite due to higher androgens, making them more likely to be overweight and obese. The current study suggests that controlling estrogen levels through birth control pills does not have a significant impact on weight control. However, a diet plan based on appetite fluctuations during the menstrual cycle can be used to achieve better weight loss. This research can tailor more effective weight loss programs and targeted health recommendations for women by understanding a deep knowledge of the impacts of estrogen in women on the food consumption and appetite. Future research could continue to explore estrogen changes in the menstrual cycle, in combination with other human hormones, provide valuable insights into weight intervention measures and drug development to tailor more effective weight management strategies for women.

Postcolonialism in the Bold, the Corrupt, and the Beautiful
Authors: Wang Ming
Published: June 2024

The history of colonization has always been expressed in many recent Taiwanese films, either intentionally or unintentionally. The 2017 film The Bold, the Corrupt, and the Beautiful is the subject of numerous studies on male gaze or feminist film noir, but few studies inspect its implicit postcolonialism. This study aims to assess the rhetorical manifestation of colonial relationships in The Bold, the Corrupt, and the Beautiful within its three main characters. Through discussing and analyzing several examples taken from the film, this study believes that Madam Tang takes the position of the colonizer in the personified colonial relationship, and her two daughters as the colonized. Moreover, two kinds of colonial relationships are discovered, which are colonial stereotype between Madam Tang and Tang Ning and colonial mimicry of Tang Zhen. The findings of the present study appear to be the first systematic research into the film’s postcolonialism in terms of its character relationships, which will be helpful in expanding the understanding of the filmic manifestation of colonial relationships worldwide.
Free vibration Analysis of Beams with Functional Gradient Materials with Cracks
Authors: Pei Zhenxing
Published: June 2024

The article presents the development of a dynamic model for a functionally graded material (FGM) beam incorporating cracks. Initially, it assumes an exponential distribution of material properties along the thickness direction of the beam and simulates the opening crack using a zero-mass rotational spring model. This approach enables the calculation of bending stiffness and local flexibility at the cracked section. Subsequently, drawing upon Timoshenko beam theory and von Kármán geometric nonlinear theory, the study formulates the energy equation of the beam and establishes the partial differential control equations for the cracked FGM using Hamilton's principle. The method of separation of variables is employed to discretize the partial differential motion equations into ordinary differential motion equations. Beam functions serve as mode functions, whose unknown coefficients are determined according to the boundary and continuity conditions, thereby yielding the natural frequencies and mode shapes of the cracked FGM beam. Numerical analysis is conducted to evaluate the impact of boundary conditions, the relative position of cracks, and the length-to-thickness ratio on the natural frequencies of the cracked FGM beam.
Research on the Aerodynamic Characteristics of the Relationship between Lift-to-drag Ratio and Wing Shape of Gliders
Authors: Liang Baoyun
Published: June 2024

A glider is a special type of aircraft without a power unit, which relies on the lift of airflow to resist weight. The characteristics of a glider are essential to its flight performance, which includes aspect ratio, sweepback, and taper ratio. Proper design of the wing shape can help achieve good performance, so research on these elements can be helpful. This paper aims to calculate the relationship between the aspect ratio and lift-drag coefficient which affects the performance of gliders. By calculation, this paper found out that high aspect ratio aircraft could generate more lift force and was optimum in designing gliders. Then an experiment with a paper plane was designed to show the impact of aspect ratio on glider performance. Then a paper airplane experiment was designed, and the changes in different aspect ratios were achieved by reshaping the wings of the paper airplane, while flight performance was estimated by the lift drag coefficient and descent angle of the glider. After data collection, calculation and analysis, different flight routes were recorded, and based on this, the lift drag coefficient and descent angle were calculated. The experimental results indicate that aspect ratio is one but not the only factor affecting the flight performance of gliders. Through theoretical analysis and experiments, this study verifies the basic mechanism of the influence of wing shape, especially aspect ratio, on glider flight, providing new ideas for improving glider performance.

Authors: Jiang Lucong
Published: June 2024

There is a clear need for dependable high-speed communication systems in light of 5G's recent rapid development. The enormous data that recently developed immersive media generate need to be transmitted, and traditional modulation techniques are unable to provide a suitable level of communication. Consequently, to improve communication system performance, hybrid modulation is needed. This paper examines the communication process and conducts a performance analysis to establish a reasonable method for choosing a hybrid modulation scheme. The constellation diagram, power spectral density, bandwidth efficiency, eye diagram, and bit error rate are the main components that determine a communication system's performance. Based on the analysis, the author concludes that to achieve a better-performing communication system, there must be a compromise between these performance factors. Specific recommendations are provided regarding performance indicators listed in the article, such as the constellation diagram, power spectrum density, bandwidth efficiency, eye diagram, and bit error rate. This work aims to address these issues to provide new researchers with guidance when selecting a hybrid modulation approach and to suggest a line of inquiry in the increasingly complicated and time-consuming age of large data volumes.

Authors: Feng Zijie
Published: June 2024

With increasing health concerns in society and the enormous surge in digital data generated from technological advancements, the need for efficient and accurate methods of value extraction from data is more evident than ever. Thus, such methods are developed to help medical professionals make thoughtful decisions. This paper explores a piece of health data from the Centers for Disease Control and Prevention (CDC) to find the most influential factors contributing to the occurrences of heart attacks and the best algorithm to help predict such occurrences. To achieve that goal, this paper employed algorithms including Support Vector Machine (SVM), Random Forest, and Logistic Regression, along with a technique called permutation feature importance to identify important features. In the end, Random Forest was found to be the most powerful and consistent algorithm to complete the task of prediction in this case, while also showing that average sleep hours, BMI, and mental health status of individuals can be potential indicators of heart attacks. With this result, this paper marks significant features and algorithms that can be subjects of further and more extensive studies, and eventually be applied to the work of real medical professionals.
