Aggression clearly has an adaptive value as it is necessary to secure resources for survival, growth, and reproduction. The Siamese fighting fish, Betta splendens, have endured a prolonged process of artificial selection for winning paired-fight contests across Southeast Asia, resulting in strains of short-fin aggressive “fighters”. Across centuries, Thai breeders have been selecting these strains by discarding loser batches and allowing winner batches to breed, claiming that they are significantly more aggressive than wild-types. This natural experiment provides a powerful context to investigate the biological basis of aggressive behaviour in fish, the topic of this thesis. To study aggression, it is important to validate and standardize behavioural assays appropriate for the species under study. Further, different aggression-eliciting stimuli, such as live opponents, 3D models, video playback, or mirror images, may elicit non-equivalent behavioural and physiological responses. For B. splendens, in particular, quantifying aggression from live fights is not ethically acceptable as the high levels of aggression of this species usually result in injuries or even death of the opponent. In Chapter II, it was shown that mirror images elicit very similar aggressive displays and endocrine responses to an interacting opponent behind a transparent partition, validating the use of this test to measure aggression in this model species. Further, it was shown that circulating levels of both androgens (11-ketotestosterone and testosterone) and corticosteroids (cortisol) increased in response to the aggression challenge, even in the absence of conflict resolution, questioning the role of these hormones during present and future aggressive contests. Using the previously validated mirror assay and also tests with live conspecifics, we assessed the impact of selection for winning by comparing, in Chapter III, male and female aggressive behaviour of lab-raised fighter and wild-type strains. The hypothesis that selection for male winners enhanced aggressive displays was confirmed, suggesting that the duration and frequency of threat and attack behaviour correlates with winning probability. However, females of the fighter strain, which are not selected for fights, were also more aggressive than wild-type females. This suggests that male and female aggression share common genetic pathways and physiological mechanisms and raises the possibility that selection for alleles that favour male aggression may have promoted intersexual genetic conflict in this species. After confirming the expected differences in aggressive behaviour between fighter and wild-type fish, the following question was whether endocrine systems, in particular those previously shown to respond to aggression, could have been targeted by the selection process. From previous studies in fish and other vertebrates, it was hypothesised that selection for winners could have increased constitutive levels of androgens or led to an enhanced androgen response to a social challenge. However, in chapter IV, it was shown that levels of 11-ketotestosterone and its response to aggression was similar in males of both strains, questioning the role of androgens in the modulation of aggression in B. splendens. On the contrary, constitutive levels of cortisol and the response of this hormone to an aggression challenge were higher in wild-type compared with fighter fish, supporting previous findings that associated high aggression with a blunted cortisol response. Overall, results from Chapter IV suggest that selection for winning had a stronger impact on the hypothalamus-pituitary-interrenal axis than in the hypothalamus-pituitary-gonadal axis. My results support the assumption of the “Challenge Hypothesis” proposed by John Wingfield and collaborators in 1990 to explain the relationship between androgens and aggression, according to which androgen levels above a reproductive baseline are a consequence of the frequency and intensity of social interactions, in particular of male-male agonistic encounters. It is becoming clear that androgens increase rapidly after an aggressive contest, independently of fight outcome. However, the function of this increase remains unclear as the frequency of aggressive displays was unrelated with post-fight androgen levels and constitutive levels of androgens, and androgen responsiveness, were similar between fighter and wild-type males. Results obtained for cortisol agree with a “corticosteroid-mediated dominance hypothesis” whereby low baseline levels and a blunted response of corticosteroids would be associated with a dominant status and high aggression. The work advances our knowledge about the endocrine regulation of aggressive behaviour in B. splendens and opens several testable hypotheses about the role of androgens and corticosteroids in the regulation of fish aggressive behaviour

China’s economy has entered a critical period of structural adjustment. The developing green industries and the transforming traditional industries have increasing demand for finance, making ""green finance"" increasingly essential. While China's green finance is in the development stage, some newly developed zones serve as pilots for the launch of green financial products. An example is Tongzhou District of Beijing, which aims to expand Beijing’s space, promote the coordinated development of Beijing-Tianjin-Hebei, and explore the optimal development mode of the densely populated economic areas. This thesis aims to study consumer acceptance of green financial technology (fintech) in the case of Tongzhou District. This thesis extended the commonly applied theoretical model for the problem of study, the Energy Augmented Technology Acceptance Model (EA-TAM), to analyze the impacts of perceived usefulness, perceived ease of use, attitude toward use, intention, usage intention, environmental awareness, and green knowledge on the acceptance of green fintech in Tongzhou District. The survey collected 403 valid responses from people that had been active in Tongzhou District. The quantitative analysis is based on structural equation modeling techniques, including reliability analysis, validity analysis, standard method deviation test, and hypothesis testing. The analytical results show that all the hypothesized factors are significant. In addition, the sample is divided into different gender groups and education groups, so that the impacts of the socio-demographic characteristics can be explored. Males’ environmental awareness and green knowledge are insignificant in determining their acceptance of green fintech. The low-educated group’s acceptance of green fintech does not significantly depend on environmental awareness and perceived usefulness

This dissertation identifies factors driving consumer shopping behavior within the realm of live-streaming commerce, an area fast emerging in the e-commerce domain. Live-streaming shopping or commerce involves real-time interaction and entertainment with traditional online shopping, forming a unique endogenous environment where consumers can contact sellers or influencers directly. The study employed quantitative surveys that identified some of the main determining factors of consumer behavior within this context. The findings show that the significant factors in determining consumer behavior are trust and engagement, which are strongly influenced by the credibility and authenticity of the live streamer. Another significant finding is the role of social interaction and community building in providing consumers with a sense of belonging and validation, enhancing their confidence and purchase intention. Moreover, it highlights how marketing strategies of flash sales, limited-time offers, and partnerships with influencers make their way into the system to help invoke engagement and impulsive buying behavior among consumers. The implications of these findings extend to e-commerce platforms and marketers. Any improvements in features leading to trust, engagement, and interactivity within the community would drive higher customer satisfaction and sales. According to researchers, working partnerships with believable influencers and more extensive integrations of real-time marketing might further activate live-streaming commerce. This study thus fills a gap in the existing body of literature by detailing the drivers of consumer behavior toward live-stream commerce. It also identifies areas of future research on the current studies, including developing technologies and the cultural variances in the impact of live-stream commerce, including ethical considerations. These results are principle for guiding work on potential live-stream commerce in the digital age for anybody from workers to academicians

In the 21st century, poverty still remains a serious issue for the world, halting development and growth of nations. SDG 1 refers to the first Sustainable Development Goal (SDG) established by United nations. It has as goal to “end poverty in all its forms everywhere”. Cape Verde as an UN member also adopted it and aligned national policies to achieve it. This thesis aimed to analyze the different policies adopted by the government of Cape Verde to implement SDG 1. Moreover, this dissertation will also point out the different actors behind the implementation of SGD 1 in Cabo Verde (both national and international actors), as well as find out their role in alleviating poverty in Cabo Verde, in other words, how they contribute to poverty alleviation in Cabo Verde. Based on a qualitative methodology, using document analysis as method to collect the data and further using thematic analysis to analyze, code and categorize the collected data, the study was able to answer the two research questions: Research question 1: What are the different policies adopted by the government of Cape Verde to implement SDG 1. Research question 2: Who and what are the roles of the actors involved in the implementation of SDG 1 in Cape Verde? The findings of the study revealed that: As to research question 1, the study found out that the government of Cape Verde has adopted several policies geared towards poverty reduction. Such policies included social protection policies, investment in infrastructure policies, investment in education policies, investment in health policies, investment in rural development policies, economic diversification policies, gender equality and women empowerment policies, job creation policies and climate change adaptation policies. As for research question 2, the study 4 revealed there are two main Actors are responsible for the implementation of SDG 1, government institutions and National and International Partners. On one hand, the government of Cape Verde is focused on creating and adopting polices that target the poor, as result this make sure that they can lift from poverty or at least avoid they sinking into deeper poverty. On the other hand, the partners (here known as Actors) helping on the implementation of SDG 1 in Cape Verde work as a backup for the government, helping it on other issues related to SDG 1 implementation such as knowledge and capital provision and so on. The Cape Verde government is dedicated to reducing poverty, focusing on the unemployment and migration phenomenon. These factors contribute to poverty and exacerbate it. Despite these challenges, the overall outlook on poverty reduction in Cape Verde is optimistic, indicating a significant commitment to address the root causes of poverty

"Cantonese opera (CO) represents an art form that had its golden time in Macao during the mid-twentieth century. CO still has many loyal fans but they mainly are in the older generation. The purpose of this study was to explore if CO is considered a cultural capital heritage in Macao, related to cultural identity and transmitted across generations to support social bonding. Applying a qualitative methodology, a script for exploring participants’ experiences and opinions about CO was designed, and different groups of individuals were recruited for semi-structured interviews and focus groups. The data collected was analysed by a thematic analysis of the verbatim transcripts. Findings show that in the past first contacts with CO happened in family and related social context, mainly during participants’ developing age. However, currently CO is no longer passed on to the next generation. Despite that the young generations acknowledging their cultural identities in CO, mainly in terms of Cantonese culture and Cantonese language, older individuals engaged with CO seemed to perceive their cultural identities more in depth in its history, literacy and music. Actually, engagement is an important factor that generates social bonds. The CO leisure practitioners, no matter young or old, experienced the effects of social bonding during the ritual of enquiry in the process of learning and practising CO. To improve CO’s preservation in Macao, the adoption of strategies such as developing new productions, crossover with other media, innovations in promotion targeting the young audiences, and absorbing audiences in the Great Bay area were proposed. Finally, the potential use of CO as a tool in counselling and community work is discussed. "

The aim of this study is comparing the jurisdiction of the National Security Law in Hong Kong SAR and Macau SAR, also reviewing the practical implementation of the law in the two SARs, analyzing the Chinese government's participation in the governance of national security in two SARs, and exploring the future sustainability of National Security Law in two SARs

Although Macau students received years of English lectures as compulsory, the outcome could be more favorable when applied to English written performance. In that written communication requires the individual to consider audience perception of the message, a challenge for ESL writers, this study explores whether different forms of feedback can enhance one’s cultural intelligence.The current study looked into the effect of incorporating peer involvement and instructor feedback in written communication, gaining insight into cultural nuances. In order to attain the objective, data were gathered through the utilization of an action research methodology employing a mixed-method design. Grade twelve local students attended a six-week six-week intervention consisting of two cycles. The focus of the intervention nurtured essay writing; the topics of which were inspired by popular musical lyrics, and involved a drafting process that incorporated feedback both from peer editing and the instructor.. The data collected throughout the study involved analysis of written samples (scores of draft and final version) using a paired samples t-test. In addition, students completed a pre-test and post-test survey of the cultural intelligence instrument (CQ), which measured their performance across four domains. There were statistically significant differences between cognitive CQ and motivational CQ between the scores attained before and directly after the intervention.. This study's findings suggest that the written communication of ESL students may be enhanced by adjusting . These findings enriched our understanding of how peer editing and teacher feedback with songs affected the outcomes of second language learners

Establishing and improving the independent reading ability of middle school students has become one of the critical topics in the world, especially for second language learners. The cultivation of independent reading ability has specific challenges. This action research investigated the effectiveness of integrating robot-assisted teaching in reading lessons at lower primary grades. A group of third-grade students (n=15) participated in this research. The instruments include the pre-and post-test of a reading competency test (RCT) and motivational index (MI), a teacher reflection journal, and focus group discussion with parents. The whole intervention is conducted in two cycles, and requires the completion of four 40-minute lessons each week per cycle. The findings support the view that integrating robot-assisted teaching in the classroom can improve students' learning motivation to a certain extent, and that intervention programs positively impact students' learning motivation and independent reading ability in English. This study provides suggestion for the design of English reading instruction, and encourages English teachers to pay more attention to improving students' independent reading ability

The development of green financial products like green bonds and industry financing has gained momentum, showing positive impacts on sustainable economic development, renewable energy investment, and greenhouse gas emission reduction. As the research problem is inadequately explored, this dissertation aims to fill the research gap to evaluate the impacts of green finance on economic development. Furthermore, this study assesses the differences between Asian and non-Asian economies in the impacts of green finance on economic development. Two empirical measures are analyzed in this study.Green finance is measured with the Global Green Finance Index (GGFI), a composite index that captures over 100 instrumental variables, covering the business environment, human capital, infrastructure, and sustainability aspects of a financial center. Growth rate of gross domestic product (GDP) per capita reflects economic development. The dataset encompasses 83 international financial centers from 2018 to 2022. The regression model finds a significant negative relationship between growth rates of GGFI and GDP per capita in the full sample, the Asian subgroup, and the non-Asian subgroup. GGFI growth is confirmed to have Granger caused GDP per capita growth, but GDP per capita growth did not Granger cause GGFI growth. Combined with the insights of the previous studies, this study justifies the findings as a short-term negative impact of green finance on economic growth. However, the Asian region, with many emerging economies, could transition faster, so the regression derives a less negative coefficients for Asian financial centers. The policy implication 5 is that continued government support to improve the effectiveness of green finance is necessary for the long-term benefit of green finance to be fully realized

This research paper analyses the marketing efforts and important attributes of Macau tea restaurants that have been open for more than 20 years, especially the digital methods that tea restaurants have used to sustain their business and meet customers' needs in the era of digital transition after the onset of the 2019 Covid 19 pandemic year. Using online marketing channels nowadays become an important tool for communicating with customers today. Despite the old Tea Restaurants in Macau did not put much efforts on digital channels for communication yet, to find out how tea restaurants survive in the rival restaurant industry in Macau, qualitative and quantitative methods were used to see how they meet the needs of their customers. For the quantitative method, an online survey questionnaire in bilingual English and Traditional Chinese was conducted with 280 respondents on customer purchase habits, importance of restaurants’ attributes and social media insights on tea restaurants, and the data was analysis by SPSS for the relationship and significance. For the qualitative method, 7 interviews were conducted with the business owners of the old tea restaurants which that have been opened for more than 20 years, including marketing efforts and their attitudes towards digitalization. To find out the marketing strategy of Macau’s old tea restaurants in the digital transformation era, it was found that “place” and “product” are the most important marketing mix for customers. Tea restaurant owners focus on product quality, and generate “word-of-mouth” which is customer-generated marketing, and is an effective way to influence customers for local tea restaurants. Meanwhile business owners will consider digitalize in the near future as well to match the new young customers’ online habits and the need for “place” such as online delivery platform

Public transportation is an important component of urban infrastructure and has a significant impact on the convenience and well-being of citizens. In Macau, with rapid economic development and urbanization, an efficient land transport system is essential to support sustainable development. Previous research has primarily focused on the sustainable development of the transportation sector in Macau, with little attention given to studies concerning employees. Therefore, the purpose of this study is to examine the impact of transformational leadership on employee work performance in the land transportation sector in Macau, with a particular focus on the mediating role of employee work engagement. Through a quantitative research methodology, this study utilized an online questionnaire to collect data from 194 employees from the bus and LRT sectors in order to achieve the research objectives. Convenience sampling and snowball sampling methods were used in this study to analyze the data through SPSS software to assess the relationship between transformational leadership, employee work engagement and employee performance. The findings reveal that there is a significant positive relationship between transformational leadership and employee performance, as well as a significant positive relationship between transformational leadership and employee work engagement. In addition, employee work engagement played a partial mediating role between transformational leadership and employee performance. The findings suggest that transformational leadership not only directly enhances employee performance, but also indirectly enhances employee performance by increasing employee work engagement. These insights have important practical implications, indicating that adopting transformational leadership behaviors can effectively enhance employee engagement and performance, thereby improving organizational effectiveness. Specifically, managers in Macau's transportation sector should pay attention to and cultivate transformational leadership behaviors in order to enhance employee work engagement and performance, and thus achieve higher organizational effectiveness and building a strong team

Vertical housing is essential for modern cities because of its efficiency in using space (Wang, J. Murakami, A. 2019). The architecture of vertical housing is often determined by developers and designers. Therefore, the architecture of the building is fixed, and the end users are not involved nor can they influence its final appearance. For residential buildings, the unit sizes are based on market demand at a given point in time, which does not reflect the dynamic needs of the population as they evolve and may result in a mismatch between the supply and the demand for housing. The design of housing towers that have demographic characteristics and family size is dependent on housing size and can be very uncharacteristic and repetitive. The research question identified and addressed in this study is: How can residential buildings meet the evolving demand for housing units? Based on this question, this research paper develops a prototype for residential to resolve the dilemma between the supply and the demand in terms of the apartment size and layout. This research is a project-oriented project that focuses on residential that reflects the different family sizes required to be housed in the building and is combined with the open building method to maximize building performance. Ultimately, this research represents a meaningful innovation for market-driven architecture and defines architectural design based on the changing needs of the population using the open construction method. It also provides an opportunity to improve the design efficiency and develop a method for future growth, upgrades, and user needs. It may also be able to reflect the current housing ratio of the residential building. This work can be further explored to verify its effectiveness for other housing types and community living spaces
