The purpose of this thesis is to assess how the use of prefabricated components alters management practices in fit-out projects and to propose effective adjustments based on real-world evidence. Focusing on the renovation of the Venetian Cotai Arena in Macau, conducted between January and October 2024, this study aims to help project managers anticipate and overcome the unique challenges introduced by prefabrication, especially in areas such as supply chain coordination, cost control, quality assurance, workforce management, and communication. Driven by rising labor costs and growing quality demands in Hong Kong, Macau, and Mainland China, prefabricated construction has emerged as a promising yet complex solution for interior fit-out projects. Despite its theoretical advantages—such as time efficiency and standardized quality—this research finds that practical management issues can offset these benefits if not properly addressed. The study adopts a qualitative case study approach, drawing on stakeholder interviews, internal meeting records, and dynamic cost analysis to investigate management failures and derive actionable insights. The findings reveal that delays in prefabricated material production and delivery were the root cause of construction inefficiencies. These delays disrupted work sequencing, led to labor idle time, and triggered costly overtime during final phases. Inadequate supplier capacity and outdated production processes contributed to this problem, while poor quality control caused dimensional mismatches and on-site rework. Cost analysis confirmed that rework expenses reached over MOP 22 million, while material and labor costs also significantly exceeded the original budget. Labor inefficiencies—driven by untrained workers and uncoordinated instructions—added further financial and scheduling pressures. Warehouse mismanagement and unclear material labeling further delayed installation work and increased operational overheads. The study concludes that prefabrication success is contingent not only on technical design but also on the implementation of proactive management strategies, including early supplier engagement, accurate production planning, effective logistics labeling, and structured site-level authority. This thesis contributes practical guidance for future projects by demonstrating how targeted management adjustments—based on real case data—can reduce cost overruns, improve coordination, and increase overall project efficiency when using prefabricated components.

Facial expression recognition is a key topic in computer vision, playing a crucial role in non-verbal communication. With the rapid development of artificial intelligence, significant progress has been made in improving recognition accuracy and generalization abilities. Traditional methods often suffer from low precision and poor generalization, while deep learning models have substantially advanced the field. However, deploying deep and complex models on different platforms remains challenging due to their high computational demands and frameworks. Hence, developing an efficient, real-time, and lightweight facial expression recognition system is critical. This study focuses on creating an efficient, accurate, and lightweight real-time facial expression recognition system with an emphasis on cross-platform deployment. It integrates various deep learning and optimization techniques to demonstrate flexibility across platforms. In this context, this study evaluates the performance of 10 advanced CNN models (VGG16, VGG19, ResNet50, etc.) on the facial expression dataset FER2013. YOLOv8 combined with ResNet50 achieved 70.56% accuracy on FER2013, outperforming YOLOv8 alone by 2.1%. Multi-module fusion models (MobileFaceNet, IR50, HyViT, SE) achieved an accuracy of 92.58% and 74.8% on the RAF-DB and FER2013 datasets, respectively, showing superior performance in ablation experiments. Given the significant impact of data quality on model performance, this study performed data cleaning on the FER2013 dataset, resulting in a 3.25% accuracy improvement for the YOLOv8 + ResNet50 model, which reached 73.81%. The high-resolution RAF-DB dataset, with fewer errors, led to improved performance, achieving 92.56% accuracy with the fusion model. A multi-purpose facial expression recognition system, VISTA, was developed using Python and PyQt5. The system supports multiple data formats and provides real-time emotional feedback, thus enhancing its usability for both research and practical applications. Furthermore, the fusion model was quantized using the OpenVINO toolkit, reducing its parameters by 75% while maintaining an accuracy of 91.17%. Inference speed was improved, and XGrad-CAM was employed to enhance model interpretability, revealing that the YOLOv8 + ResNet50 combination more effectively captured facial features. Finally, the high-performance model was successfully deployed on Intel CPUs, NVIDIA GPUs, and embedded devices Raspberry Pi 4B, demonstrating the portability and flexibility of the VISTA system across various platforms. This research provides promising solutions for applications in human-computer interaction, affective computing, and real-time emotional analysis, with significant advancements made in improving system real-time performance, accuracy, and cross-platform deployment capabilities. It contributes to the development of facial expression recognition technology and lays the foundation for its widespread future applications in fields such as smart healthcare, business analytics, education, and mental health.

This dissertation investigated the impact of nature exposure, namely access to green elements, and time spent outdoors on well-being, specifically experiences of positive and negative affect and flourishing, in Macao. Drawing on existing literature, the study proposes the following hypotheses: H1: Access to green elements has a positive relationship with positive affect. H2: Time spent outdoors moderates the relationship between access to green elements and positive affect, in that more time spent outdoors will strengthen the relationship. H3: Access to green elements has a negative relationship with negative affect. H4: Time spent outdoors moderates the relationship between access to green elements and negative affect, in that more time spent outdoors will weaken the relationship. A quantitative methodology utilising cross-sectional self-response questionnaires was employed for data collection. The measures used were pre-validated and translated into Chinese through a rigorous translation and back translation process. The final sample consisted of 740 participants from different industries in Macao. The results highlight the significance of integrating natural elements in daily life to promote flourishing and positive affect. The implications of these findings, both in theoretical and practical terms, are thoroughly discussed. The findings offer valuable insights for the implementation of the biophilic practices by counsellors, educators, health professionals, urban planners, employers and other decision makers.

This research examines aspects that influence career development for women in the public sector in Macau. The combination of local customs and what remains from Portuguese rule in Macau has led to a special society that influences how gender is dealt with in public institutions. While nations promise gender equality, women do not hold many leadership positions in their government agencies. To conduct this study, qualitative research using semi-structured interviews was performed with 12 female public sector staff, some in leadership positions and some aiming for them. Analysis of interview data shows that cultural norms, organizational structures and new technological trends together block women from advancing at work. It appears that strong cultural habits about gender keep valuing women’s domestic duties over professional goals, supporting the belief that top management should be mostly male. Women in these sectors which are largely male, are doubted about their ability to lead. Organizational barriers, including opaque promotion practices, gender-biased recruitment, lack of mentorship, and limited access to gender-sensitive leadership development programs, further impede women's career advancement. Even though work-life balance policies exist in the handbook, managers often ignore them and consider them a hindrance for women hoping to move ahead.In parallel, the study explores how digital transformation—the so-called "Internet+" era— offers both opportunities and challenges for women in the public sector. Although digital tools improve skills and career paths, poor training often keeps women from gaining from these resources. The impact of digitalization brings out more gender inequality, because women find it harder to access major leadership roles in high-tech sectors. To tackle these different problems, the dissertation recommends strategies such as running gender-focused mentorship programs, making sure work-life balance policies are properly enforced, increasing transparency during promotions and launching digital skill training just for female employees. Equally importantly, it stresses the need for shifts in cultural values together with new policies, encouraging campaigns to raise awareness and welcoming new leadership models opposed to patriarchy. The research, by considering Macau’s special setting, helps advance the debate on gender equity in governance and provides useful tips for supporting inclusive leadership paths in societies with similar characteristics.

The Tokyo 2020 Olympic and Paralympic Games established themselves as a unique worldwide sports event, which took place in 2021 without spectators after a year-long delay due to the COVID-19 pandemic. The media became the sole information distributor about the Games because there were no live spectators present at the events. Academic research about the Paralympic movement showed substantial growth since the London 2012 as media attention alongside public interest expanded. Research about the Tokyo 2020 Paralympics faces limited availability because of immigration and infection control measures combined with spectator restrictions. There is insufficient research about the social consequences of the Paralympic media coverage especially from the viewpoint of people with disabilities. This study analysed the Tokyo 2020 Paralympics through qualitative methods to understand media communication effects on Tokyo and Aichi Prefecture residents with disabilities. Four main themes emerged through reflexive thematic analysis of semi-structured interview dataset which included: 1) the duality of the media, 2) the suspension between the medical and social models, 3) Japanese culture and the human rights movement, and 4) Paralympian decoded. By comparing with previous research on media perception among Japanese non-disabled people, this study revealed that people with disabilities viewed the Paralympic media coverage with both critical and objective perspectives by acknowledging its benefits and challenges. People with disabilities demonstrated little optimism regarding how the media could improve public disability awareness. The study also revealed that Paralympians carry diverse and widely recognised social meanings within disability communities and that a fundamental mismatch exists between disability goals and mainstream media representations, which tend to simplify disability into one-dimensional categories. This study established a social framework that recognised and respected the diverse differences within the disability population, rather than using reductionist classification systems.

As individuals reach 35, they often find that others no longer view them as young. Various theories of adult development suggest that the shift into middle age officially begins at 40. This stage is seen as a transitional period leading toward middle age, commonly referred to in our context as the ""35-year threshold"" or ""35-year crisis."" Therefore, the transformations and significant decisions faced by those aged 35 to 40 deserve attention to better understand the support necessary for a smooth transition into middle age. Research on those in the 35 to 40 age bracket is limited in many regions. This study seeks to identify the needs of early adults within this age group in our area, utilizing qualitative methods. By conducting in-depth interviews about the life experience of the interviewees and starting up writing the stories with the dimension of phenomenological pedagogy, we aim to capture participants' subjective experiences, shedding light on the psychological aspects of their decision-making during pivotal life events. In total, 20 participants aged 35 to 40 from our region were invited to contribute to this study. After three months of interviews and five months of analysis, the research identified four key factors influencing their decision-making attitudes toward major life events: a primary focus on family considerations, a perceived urgency to enact changes before turning 40, a pursuit of stability, and a desire for self-actualization while letting go of rigid expectations. Additionally, based on participants’ insights regarding support systems for Macau adults in this age group, five recommendations were proposed: enhancing family welfare policies, regular reviews of housing policies, promoting life education and diversified development for youth, addressing workplace stress and fostering continuous professional development, and increasing awareness of mental health. These measures aim to provide better support for individuals navigating life transitions or challenges. In summary, the insights gathered from participants provide important implications for adults, government bodies, and social workers regarding the services needed. This research underscores the essential support services for those aged 35 to 40 and suggests the creation of more customized programs and resources. 當踏入35歲後在別人眼裡已不再年輕，在許多成人發展理論定義上則認為踏入40歲後才算中年階段，35歲後正要開始步向中年的過渡時期，國內更稱為「35歲門檻」及「35歲危機」，所以35至40歲這個年齡階段的生活遇到的轉變和重大事件決策歷程，從而了解那些支援能讓這個年齡階段能順利過渡至中年階段，亦是值得進行探討及研究。 不同地區亦較少對35至40歲這個年齡人士進行研究，本研究為了解本澳35至40歲成年早期人士的需要，研究會採用質性研究，以深度訪談了解受訪者在研究題目當中有關的生活體驗，並以教育現象學作分析，期望從受訪者主觀表述其經驗，以了解35至40歲成年人士對於生活中重大事件的決策深層心理意涵與其真實想法。 本次研究共邀請20位本澳35至40歲之成年人士為對象，經過3個月的訪談及歷時5個月進行探討及總結，研究分析得出這個年齡階段之人士，他們面對重大事件作出決策取態的結果有以下四大重要元素：本澳35至40歲成年早期人士首先以家庭角度出發，其次認為時間不多需要在40歲前作出轉變並且追求穩定的生活，追求自我價值及放下執着。 另外，從受訪者提及如何支援本澳35至40歲之成年人的生活，共歸納出五項建議：完善家庭福利措施、定期檢視房屋政策、青年生命教育及多元發展、在職人士壓力及持續進修發展、促進心理健康的關注，讓他們能更有支援的情況下應對生活的轉變或挑戰。 最後，從各位受訪者的建議中整理及歸納，為成年人、政府相關單位及社會工作者在服務提供相關啟示，更能補充35至40歲這個年齡階段人士的生活所需之服務，以及作出更合意的支援方案與服務資訊作參考。

This study examines consumer perceptions of all-electric vehicles in Macau, focusing on Tesla owners. As the Macau Special Administrative Region (MSAR) pursues its long-term carbon reduction strategy, adopting BEV is a key step towards sustainable urban mobility. However, consumer attitudes and behavioral responses to BEV in Macau's unique high-density urban environment remain underexplored. This study adopts the extended Unified Theory of Acceptance and Use of Technology (UTAUT-2) model with the addition of the “technological show-off” (TS) dimension to explore how Tesla owners perceive the challenges and opportunities of adopting BEV. This study used a qualitative methodology to conduct in-depth interviews with ten Tesla owners in Macau through semi-structured interviews and unstructured quantitative assessments. Data were analyzed across multiple UTAUT-2 dimensions, including Performance Expectancy, Effort Expectancy, Social Influence, Facilitating Conditions, Hedonic Motivation, Price Value, Habit, and the added factor of Technology Show-Off. The findings suggest that Tesla owners in Macau value their vehicles' convenience, efficiency, and technological sophistication, with a particular focus on Autopilot, acceleration, and low maintenance costs. However, issues such as limited charging infrastructure, service accessibility, and technology learning curve remain. Social status and identity are influential factors, especially in a compact and socially connected urban environment like Macau. By examining the experiences of EV users, this study fills a gap in the existing literature. It provides practical insights for policymakers and manufacturers aiming to accelerate the diffusion of BEVs. The study concludes that consumer perceptions are critical for practical benefits and emotional fulfillment for the continued growth of the electric vehicle market in Macau and similar regions.

Legalizing gambling has brought numerous advantages to Macau, including employment opportunities, economic growth, improved quality of life, and accelerated urban development. While these macro-level benefits are evident, the industry has also significantly impacted local families and communities. In particular, the initial discovery of a family member's gambling problem inflicts immeasurable harm on the household, and the coping strategies adopted by affected family members critically influence their relationships with the gambler and the overall trajectory of the family unit. This qualitative study, conducted in collaboration between the University of Saint Joseph (USJ) and SKH 24-hour online gambling counseling service (SKH-24H), employed semi-structured interviews to explore the coping strategies of family members of problem gamblers. Nine participants were interviewed, and thematic analysis revealed eight key coping strategies: (1) Bailing out The Problem Gambler, (2) Maintaining Status Quo of the Family, (3) Help Seeking in Macau Community, (4) Coping by Self-Regulation, (5) Coping by Engagement, (6) Coping by Withdrawal, (7) Tolerance and (8) Seeking Psychiatric Consultations. The study aims to enhance the understanding of local gambling counseling professionals regarding the coping strategy employed by Macau families dealing with problem gamblers. By aligning intervention strategies with the lived experiences of these families, the findings can inform more effective, family-focused approaches to service delivery. Furthermore, the research provides insights for government agencies into the real-world challenges faced by families affected by problem gambling, offering evidence-based recommendations for evaluating and revising existing regulations to mitigate the adverse effects of the gambling industry on Macau's households.

This study provides an empirical assessment of public servants’ integrity in Macao’s public sector, exploring how integrity is perceived, practiced, and promoted amid Macao’s unique administrative and socio-cultural context. Drawing on in-depth, semi-structured interviews with ten public servants from diverse departments and hierarchical levels, the research adopts a qualitative approach guided by the Theory of Public Service Motivation (PSM). The findings reveal that integrity fundamentally prioritizes public interest above personal gain, grounded in honesty, self-discipline, and ethical commitment. While organizational missions and formal codes offer guidance, individual values, professional ethics, and personal motivation are central to upholding integrity. Key enablers include mission-driven values, ethical leadership, supportive organizational culture, non-monetary incentives, and recognition. However, integrity is undermined by inconsistent ethics training, weak supervision, ineffective reporting mechanisms, and cultural factors such as close social networks and fear of retaliation. The effectiveness of mechanisms, such as internal regulations, anti-corruption agencies, and ethics training, varies across departments, often hindered by procedural gaps and societal norms. The study concludes that sustaining integrity in Macao’s public sector requires strengthening ethics education, enhancing leadership and culture, improving internal systems, and addressing systemic and societal risks. Limitations include the small, non-generalizable sample and focus on qualitative insights. Recommendations are targeted at policymakers, the supervisory institution, the Commission Against Corruption (CCAC), and institutional leaders for future reforms.

This dissertation conducts a comparison of French Nouvelle Cuisine and Japanese Kaiseki Cuisine, exploring the similarities and differences of both cuisines and reflecting how cultural values, philosophical aspects, and historical influences have shaped contemporary dining experiences. In the examination of both cuisines, it takes into consideration aspects such as sensory experience, plating, and their underlying philosophical principles to demonstrate the interaction between aesthetics and culture particularly in relation to the culinary arts. French nouvelle cuisine was influenced by the Enlightenment, and this type of Western cuisine highlights a focus on texture and balance in flavor, emphasizing freshness, innovation, and intellectual artistry. Kaiseki cuisine inherited the tradition of the Japanese tea ceremony and is essentially rooted in Zen Buddhism. Some of the core aesthetic concepts in Kaiseki cuisine include seasonality, simplicity, and the aesthetic concept of wabi-sabi, emphasizing how humans should live in harmony with nature. As these two types of cuisines are compared, there will also be a comparison of Immanuel Kant’s aesthetics and how it is related to French nouvelle cuisine, as representative of a Western philosophical view and this will be compared to Japanese aesthetics in general and, in particular, the views on aesthetics of the Japanese philosopher Daisetsu Teitaro Suzuki, as representative of an Eastern philosophical view and its relation to culinary arts.

This research focuses on the design of the in-vehicle interactive interface of L4 autonomous driving vehicles, aiming to explore how to improve the passengers experience by optimizing the interface interaction mode. With the development of autonomous driving technology, the shortcomings of existing interface design in transparent feedback, emotional adaptation and multi-modal interaction support have become the main obstacles affecting user trust and satisfaction. Based on user research and prototype design, the study proposed an interface design scheme that combines transparent feedback with emotional perception, focusing on real-time display of vehicle behaviour logic and dynamic adaptation to passenger emotional state. In user testing, the system showed some improvements in trust enhancement and ease of use, especially in response to complex road conditions and emergencies. Although this research has provided some preliminary results through innovative design, there are still limitations in technical implementation and scope of application. Future research will focus on sample diversification and accuracy improvement of emotional perception technology to further improve the design scheme and expand its application scenarios.

This dissertation investigates the effectiveness and shortcomings of employee incentive mechanisms at GF Advertising Company, with a specific focus on the motivation of staff. Amid rapid changes in the advertising and printing materials industry, employee satisfaction and retention have become increasingly critical. However, the company’s current incentive system—characterized by an overreliance on material rewards and lack of development opportunities—has struggled to meet employees’ evolving needs. To explore this issue, the study adopts a mixed-methods approach, combining a quantitative survey of 115 employees with qualitative interviews of 7 selected staff members. The research draws upon Maslow’s Hierarchy of Needs and Herzberg’s Two-Factor Theory to analyze employee motivation and satisfaction. The findings reveal key challenges in four areas: insufficient economic incentives, weak organizational environment support, underdeveloped career growth mechanisms, and ineffective work-related motivation. Based on the results, the dissertation proposes a multi-layered, localized incentive model that incorporates both intrinsic and extrinsic motivators. Recommendations include optimizing communication platforms, strengthening team culture, refining promotion pathways, and diversifying reward structures to better align with employee expectations. The study concludes that a strategic and human-centered incentive mechanism not only improves employee engagement but also enhances organizational performance. Future research could further expand the sample scope and explore long-term impacts of different incentive models across companies and regions.

With the steady growth of the global population and the acceleration of the urbanization process, the carbon footprint generated by the food production system and thus by food waste (40 % of food is wasted globally) has a significant impact on the environment and for sustainable development. Dongguan, as a new first-tier city in China, has attracted many internal migrants from China to work and settle down. A large proportion of the city's waste is composed of organic waste, and household food waste is an important part of it. This may be due to the fact that families purchase too much food, set aside excessive amounts, or fail to consume the food before it spoils, resulting in a waste of resources that comes along with significant environmental impacts, especially in the form of greenhouse gas emissions. This research adopted the method of questionnaire survey. The questionnaire aims to gain an in-depth understanding of the food waste perception and situation in Dongguan’s household sector and its families. By covering questions in three aspects: the demographic information of the respondents, their views and perceptions of local food waste, and their behavioral habits, the questionnaire investigates the current situation and local challenges of household food waste in families (such as the situation of leftover dishes, the proportion of food waste in household garbage, etc.), analyzes the causes of waste (factors in links such as purchasing, cooking, and storing), explores the wider public's awareness and attitudes towards food waste (degree of attention, views on reduction measures, environmental awareness, etc.), and clarifies the behavioral habits of dealing with leftover food (handling methods, willingness to purchase discounted food, etc.), and analyzes the relationship between demographic characteristics and food waste, so as to provide a basis for formulating targeted strategies. The survey results show that there exists a significant degree of food waste in Dongguan households. The public's awareness and behavioral habits regarding food waste vary greatly, and there is much room for improvement and enhancement. It is urgent to strengthen publicity and education work, which will help improve the public's understanding of the harm of food waste and enhance their environmental awareness. The research finds that although the Dongguan Municipal Government attaches great importance to the problem of food waste, the current policies mainly focus on the catering industry. In terms of the governance of food waste at the family level, relevant measures still need to be further strengthened. This study analyzes the factors affecting household food waste generation and comprehensively reviews and evaluates relevant policies aimed at mitigating food waste in Dongguan. On this basis, this study provides preliminary suggestions for policymakers and government departments on regional and national level, aiming to point out the direction for future related research and work planning.

<jats:p>To better inform the public about ambient air quality and associated health risks and prevent cardiovascular and chronic respiratory diseases in Macau, the local government authorities apply the Air Quality Index (AQI) for air quality management within its jurisdiction. The application of AQI requires first determining the sub-indices for several pollutants, including respirable suspended particulates (PM10), fine suspended particulates (PM2.5), nitrogen dioxide (NO2), ozone (O3), sulfur dioxide (SO2), and carbon monoxide (CO). Accurate prediction of AQI is crucial in providing early warnings to the public before pollution episodes occur. To improve AQI prediction accuracy, deep learning methods such as artificial neural networks (ANNs) and long short-term memory (LSTM) models were applied to forecast the six pollutants commonly found in the AQI. The data for this study was accessed from the Macau High-Density Residential Air Quality Monitoring Station (AQMS), which is located in an area with high traffic and high population density near a 24 h land border-crossing facility connecting Zhuhai and Macau. The novelty of this work lies in its potential to enhance operational AQI forecasting for Macau. The ANN and LSTM models were run five times, with average pollutant forecasts obtained for each model. Results demonstrated that both models accurately predicted pollutant concentrations of the upcoming 24 h, with PM10 and CO showing the highest predictive accuracy, reflected in high Pearson Correlation Coefficient (PCC) between 0.84 and 0.87 and Kendall’s Tau Coefficient (KTC) between 0.66 and 0.70 values and low Mean Bias (MB) between 0.06 and 0.10, Mean Fractional Bias (MFB) between 0.09 and 0.11, Root Mean Square Error (RMSE) between 0.14 and 0.21, and Mean Absolute Error (MAE) between 0.11 and 0.17. Overall, the LSTM model consistently delivered the highest PCC (0.87) and KTC (0.70) values and the lowest MB (0.06), MFB (0.09), RMSE (0.14), and MAE (0.11) across all six pollutants, with the lowest SD (0.01), indicating greater precision and reliability. As a result, the study concludes that the LSTM model outperforms the ANN model in forecasting air pollutants in Macau, offering a more accurate and consistent prediction tool for local air quality management.</jats:p>

Macau is a Special Administrative Region (SAR) located in the south of the People’s Republic of China (PRC). Settled by the Portuguese it was the last European colony in Asia. Over the centuries as a maritime city Macau saw its fortunes coming as trade boomed in the 16–17th centuries; however, with the establishment of Hong Kong as a port city the importance of Macau decreased. The authorities resorted to gaming and tourism as key sources of tax revenues eventually in 2000s becoming ‘Las Vegas’ of Asia. As the pandemic hit China and the rest of the world, Macau was isolated, gaming revenues declined temporarily and the Macau authorities decided to diversify its offer of tourist attractions. Although Macau has already been recognised as a UNESCO heritage site with a well-preserved historic core since 2005, two new attractions were developed to help reposition Macau as a city with a rich cultural history. The two new sites that opened in 2023 were the long abandoned Iec Long firecracker factory (益隆炮竹厂) in Taipa and dilapidated Lai Chi Vun shipyards in Coloane. Iec Long firecracker factory is unique, as it blends an interface with nature (green space dominated by the century old trees), a public space and interpretative displays of how the industrial activities were performed. In this paper we use mixed methods approach to provide a ‘thick description’ of Iec Long firecracker factory as an interplay of affective and material elements. Drawing on the existing literature we further advance how assemblage thinking can contribute to analysis of industrial heritage sites as tourist attractions. Additionally, drawing on the first-hand empirical data and the context of ongoing urban revitalization in Macau we scrutinise heritage-tourism dichotomy and demonstrate how we can better understand the meanings of heritage co-created from below.

We derive the vacuum energy from the zero-point quantum fluctuations after imposing a natural constraint emerging from the rotational symmetry inside the de-Sitter metric. The constraint imposes a maximum azimuthal angle for each frequency mode emerging from the vacuum. In this way, the shorter the wavelength of the mode, the larger will be its suppression. The same result is derived subsequently by using the Friedmann–Lemaitre–Robertson–Walker (FLRW) metric. We then make a physical interpretation of the physical effects from the perspective of pair creations over the vacuum, where the mentioned constraint emerges, limiting then the maximum angle which each pair generated from the vacuum can rotate with respect to each other during their short existence.

This dissertation examines the customs procedures governing trade in Macao, a Special Administrative Region of China, focusing on their role in facilitating trade within the Greater Bay Area. Adopting a qualitative approach, the study conducts in-depth interviews with stakeholders, including local businesses, customs officials, and trade experts, to identify factors affecting the efficiency and transparency of customs processes, such as clearance, licensing, and declarations. The research is significant as it enriches the theoretical framework of trade facilitation in Macao, where literature is scarce, and provides practical insights for customs authorities and traders. Findings reveal bureaucratic complexities, technological gaps, and documentation burdens, particularly impacting small and medium enterprises. Three additional factors influencing trade efficiency—regional integration, stakeholder coordination, and policy alignment—are identified. The study recommends streamlined licensing, enhanced digital systems, and SME-focused training to foster sustainable trade development. These insights offer actionable guidance for policymakers and practitioners to strengthen Macao’s position as a regional trade hub.

This paper explores the entrepreneurial perception and challenges of African students from Portuguese-speaking countries (PSC) in Macau, adopting a qualitative research method and conducting in-depth interviews with ten students from this geographic area to understand their Perceptions and challenges towards the entrepreneurial field. This study is significant because it enriches the theoretical guidance framework. Moreover, it helps future researchers utilize valuable data for their research in the field with many samples. The insights obtained from this paper might inform policymakers and universities about the necessary framework to support international students, especially African students from Portuguese-speaking countries, in a way that can encourage them to pursue entrepreneurial opportunities. In-depth interviewing is the primary method for data collection. The thematic content analysis (TCA) An approach is utilized to analyze the data from interview transcripts. Existing research illustrated students from this geographic area's entrepreneurial perception and challenges, as well as their aspirations and intentions as planned after their study. From the point of view of the researcher's interview with his sources, the researcher discovered that there is no opportunity for them to pursue an entrepreneurial career in Macau, which means that, after their study, they will return to their motherland. III In conclusion, based on the findings, understanding the entrepreneurial perception and challenges Students from this geographic area can help to provide support from the local Government and Universities, based on their field of study in a way they can have the opportunity to explore practical experience in a working environment for their personal and professional development.

Aggressive behavior is an adaptive trait present across all taxa. However, the neuroendocrine mechanisms regulating it, particularly in fish, are not well understood. Oxytocin (OXT) and arginine vasotocin (VT) are known modulators of aggression, but their actions remain controversial. This study tested the possible modulation of endocrine and behavioral responses to an aggression challenge by these nonapeptides in Siamese fighting fish, Betta splendens, a species known for its intrinsic aggressiveness. Male B. splendens were injected with different dosages of either Manning compound or L-368,899, VT and OXT receptor antagonists respectively, and were exposed to a mirror challenge for 30 min. While all fish displayed high levels of aggression toward their mirror image, no differences were observed between control-injected and treatment fish. However, blocking VT inhibited the post-fight increase in plasma levels of the androgen 11-ketotestosterone (KT). To further investigate this result, testis tissue from males was incubated with and without VT and Manning compound, and KT levels were measured after 180 min. Results showed a direct effect of VT on in vitro KT secretion, indicating the presence of VT receptors in the testes of this species. Overall, the study does not support a modulatory role of VT or OXT in aggressive behavior, although VT might be implicated in the regulation of peripheral androgen response to aggression in B. splendens.
