Abstract

Purpose

Docking technology plays a crucial role in enabling long-duration operations of autonomous underwater vehicles (AUVs). Visual positioning solutions alone are susceptible to abnormal drift values due to the challenging underwater optical imaging environment. When an AUV approaches the docking station, the absolute positioning method fails if the AUV captures an insufficient number of tracers. This study aims to to provide a more stable absolute position visual positioning method for underwater terminal visual docking.

Design/methodology/approach

This paper presents a six-degree-of-freedom positioning method for AUV terminal visual docking, which uses lights and triangle codes. The authors use an extended Kalman filter to fuse the visual calculation results with inertial measurement unit data. Moreover, this paper proposes a triangle code recognition and positioning algorithm.

Findings

The authors conducted a simulation experiment to compare the underwater positioning performance of triangle codes, AprilTag and Aruco. The results demonstrate that the implemented triangular code reduces the running time by over 70% compared to the other two codes, and also exhibits a longer recognition distance in turbid environments. Subsequent experiments were carried out in Qingjiang Lake, Hubei Province, China, which further confirmed the effectiveness of the proposed positioning algorithm.

Originality/value

This fusion approach effectively mitigates abnormal drift errors stemming from visual positioning and cumulative errors resulting from inertial navigation. The authors also propose a triangle code recognition and positioning algorithm as a supplementary approach to overcome the limitations of tracer light positioning beacons.

Abstract

Purpose

This paper aims to examine the USA's policy toward Myanmar or Burma, analyzing the bilateral relationship between the two countries from the pre-colonial period to the present day. It highlights the implications of political shifts in the system of government in Myanmar for the bilateral relationship with the USA, particularly after the 1962 coup and the emergence of rising regional powers like China. The paper also shows how the economic role of Myanmar has increased, leading to more equal relations with the United States of America.

Design/methodology/approach

This paper employs a qualitative research design, analyzing data from both primary and secondary sources. The methodology includes a literature review and document analysis to gain a comprehensive understanding of the USA–Myanmar bilateral relationship. The research also analyzes political and economic developments in Myanmar and the region, placing the USA policy in a broader context.

Findings

The research finds that the USA has been an influential player in Myanmar's politics and economy. However, with Myanmar's integration into the Chinese Belt and Road Initiative and its accession to Association of Southeast Asian Nations (ASEAN), its economic role has become more significant, leading to a more balanced relationship with the USA. The paper also shows that the USA's policy toward Myanmar has undergone significant changes, particularly after the 2011 easing of sanctions by former President Barack Obama.

Originality/value

Although many works have traced the history of USA–Myanmar ties, this study provides a fresh perspective by setting past events against the backdrop of contemporary geopolitical upheavals, therefore highlighting the complex evolution of their bilateral dynamics. The paper contributes to the literature on the USA–Myanmar bilateral relationship by providing a comprehensive analysis of the relationship from a historical perspective. The research also adds to the discussion of the implications of political and economic developments in Myanmar for the bilateral relationship with the USA. The findings of this study have important implications for policymakers and scholars interested in the USA's role in Southeast Asia and its relations with rising regional powers like China.

This study aimed to assess emotional intelligence (EI) among young adults across three Arab countries: Egypt, Jordan and the United Arab Emirates.

Abstract

Purpose

This study aimed to assess emotional intelligence (EI) among young adults across three Arab countries: Egypt, Jordan and the United Arab Emirates.

Design/methodology/approach

A total of 1884 university students participated from the three countries and completed the Schutte Self Report Emotional Intelligence Test (SSEIT). Data were validated by confirmatory factor analysis using SPSS AMOS version 29. Path analysis, t-tests and analyses of variance were performed to understand the influence of background variables on the EI of the study participants.

Findings

The results provide theoretical support for the SSEIT and the hypothesized relationship between managing personal and others' emotions. Although significant differences were found between participants in terms of gender and grade point average (GPA), no difference was found between participants based on nationality. The results of this study indicate the need to prioritize EI in young adults and other implications.

Originality/value

The importance of EI in individuals' daily lives cannot be overemphasized. However, scholarly insights into the state of EI in the Arab context are scarce.

Abstract

Purpose

This paper aims to examine the mediating role of occupational stress in addressing the missing gap between organisational intelligence (OI) traits and digital government service quality.

Design/methodology/approach

By employing multistage cluster sampling, a total of 394 responses from the Malaysian service providers at federal government agencies were obtained. For data analysis, the partial least square structural equation modelling (PLS-SEM) approach with a disjoint two-stage approach was employed to assess the proposed higher-order model. The analysis was carried out to examine how occupational stress mediates the relationship between OI traits at each component level and digital service quality.

Findings

Occupational stress mediates the relationship between OI traits at the third-order component level and digital service quality. At the second-order component level, only the employee-oriented OI traits exhibit a significant indirect effect on the digital government service quality. Narrowing down to the first order component level, two OI traits, namely “Alignment and Congruence”, and “Heart” demonstrate significant indirect effects in the mediation analysis.

Originality/value

By incorporating the organisational model of stress (OMS) with public service-dominant logic (PSDL), this paper takes an approach to revitalise the stressors and individual-level performance used in a traditional work setting. Precisely, it examines how digital service quality is influenced by today's high-performing public organisation stressors (OI traits) along with non-technical element (occupational stress). More importantly, digital government service quality was examined from a less emphasised perspective, namely the supply side or service providers’ standpoint in sustaining the digital government service performance.

Abstract

The recent outbreak of Coronavirus disease has caused significant disruptions around the world. The global pandemic severely affects the education sector. However, amid the crisis, educators are resilient and resourceful and develop innovative ideas and learning designs to engage the students as much as possible. Educators in the special and inclusive education sector face more challenges due to the nature of students. The effective use of technology and mindset are the keys to success in this endeavour. This chapter discusses the institutional policies, good practices and practical ideas to overcome the difficulties in inclusive and special education students.

Abstract

As the P-12 student landscape continues to grow in cultural and linguistic diversity, teacher preparation programs have yet to adequately prepare teacher candidates' teaching and learning skills in meeting the academic and socio-emotional needs of diverse student demographics. This article examines teacher candidates’ cultural competence and cultural responsiveness to enhance candidates' educator preparation and stimulate candidates' personal growth development as developing culturally and linguistically responsive new teachers. While many teacher preparation programs require one multicultural or diversity education course, the authors examine a minority serving institution's integration of a cultural immersion experience for teacher candidates as one way of supporting their development as culturally and linguistically sustaining pedagogues. This paper aims at supporting school districts' need of culturally competent new teachers who have the content knowledge and pedagogy to teach and support culturally and linguistically diverse children. Recognizing this need, this qualitative analysis highlights the importance of and a need for cultural and linguistic competence among teacher candidates. Findings from this study provides a means by which universities can implement cross-cultural coursework and field-based experiences to prepare culturally responsive teacher candidates.

Abstract

Governments in Southeast Asia have introduced and enforced harsh legal measures to stem the spread of COVID-19. These measures are disproportionate to the crisis and disregard fundamental human rights. Against this backdrop, public trust in government among Southeast Asians nevertheless remains relatively high – paradoxically, people living in authoritarian regimes tend to trust their governments more compared to people living in democratic regimes. The chapter examines the impacts that anti-COVID-19 legal measures have left on the protection of human rights and the seemingly paradoxical divorce between public trust and the diminished respect for fundamental human rights. Based on this examination, this chapter also proposes elements that any global treaty for future pandemic response must include in order to ensure the protection of human rights.

Abstract

Globally, the COVID-19 pandemic has been in effect since 2019. It has impacted people's lives differently, and education is one of the biggest challenges. In Myanmar, apart from the pandemic, the Coup d’état in 2021 crippled development across many sectors, including education. Consequently, they interfered with Myanmar's progress toward inclusive education in line with Sustainable Development Goal Four (SDG 4). A brief overview of Myanmar's progress and challenges in implementing inclusive education is provided in this chapter. Furthermore, it aims to bring ideas on how inclusive education in Myanmar could improve in the aftermath of the pandemic and coup.

Abstract

Purpose

Unlimited quantitative easing (QE) is one of the monetary policies used to stimulate the economy during the coronavirus disease 2019 (COVID-19) pandemic. This policy has affected the financial markets worldwide. This empirical research aims at studying the dependence among stock markets before and after unlimited QE announcements.

Design/methodology/approach

The copula-based GARCH (1,1) and minimum spanning tree models are used in this study to analyze 14 series of stock market data, on 6 ASEAN and 8 other countries outside the region. The data are divided into two periods to compare the differences in dependence.

Findings

The findings show changes in dependence among the volatility of daily returns in 14 stock markets during each period. After the unlimited QE announcement, the upper tail dependence became more apparent, while the role of the lower tail dependence was reduced. The minimum spanning tree can show the close relationships between stock markets, indicating changes in the connection network after the announcement.

Originality/value

This study allows the dependency to be compared between stock market volatility before and after the announcement of unlimited QE during the COVID-19 pandemic. Moreover, the study fills the literature gap by combining the copula-based GARCH and the minimum spanning tree models to analyze and reveal the systemic network of the relationships.

Abstract

Purpose

Executive decisions regarding capital financing are an important management aspect, especially during financing constraints and growth opportunities. The current study examines the impact of managerial skills of a company on capital financing decisions. Furthermore, it analyzed this nexus in financing constraints and growth opportunity situations.

Design/methodology/approach

The authors use the GMM (generalized method of moments) estimation approach on a dataset of 20,651 firm-year observations of Chinese A-share companies from 2010 to 2019.

Findings

The authors’ findings are compatible with management signaling and reputation enhancement theories, since they show that managerial skill is connected with more substantial debt financing. Managers with high management skills are likely to have more debt financing as they can foresee the economic future of their companies and tactfully convey private information, lowering information inequality and enhancing their reputation. Furthermore, the authors also show that firms with restricted financial resources and growth opportunities make this relationship stronger. Capital structure and managerial skill findings are unaffected by alternative specifications, omitted factors, industry group bias and endogeneity.

Originality/value

This study sheds fresh light on the essential manager personality trait of managing ability and how it influences complicated corporate decision-making, particularly in the tough environment due to financing constraints and competitive growth. The authors argue that high-ability managers are compelled to use debt financing not only to lessen information asymmetry but also to guarantee that the market finds their superior ability. This work contributes significantly to the managerial ability literature and the capital structure literature supporting signaling theory.
