Abstract

The main aim of this study is to measure the dynamic connectedness and spillover effects among emerging stock markets in Asia and the developed stock markets of the US and Europe in the ongoing Ukrainian crisis. The paper also aims to provide a comparative analysis of return and volatility spillovers during the global financial crisis in 2008, the COVID-19 pandemic, and the Ukrainian crisis. This paper utilizes the multiple structural beak test of Bai & Perron (2003) and also depicts the risk and return transmissions among these markets using the Diebold & Yilmaz (2012) method. The main outcomes of this study indicate that the stock markets in Asia are less affected by the political crisis in Ukraine as compared to the previous effects during the GFC and COVID-19 periods. The results also show that sensitivity of Asian financial markets to global shocks has been weakened in the wake of the Ukrainian crisis in favour of increased resilience of Asian stock indices to external shocks. These results carry an important implication for international and local investors as well as for policy makers in Asia, where investors have greater potentials for portfolio diversify and risk reduction across Asian markets. Doi: 10.28991/ESJ-2023-07-02-04 Full Text: PDF

Abstract

The objective of this study was to construct a model of the link between sports resources and the model of national sports event management and the added value of Thailand's sports sector. Mixed methods were implemented in this study. The causative and result link between sports resource variables and national sporting practices and the added value of the Thai sports sector were examined using quantitative research. Using questionnaires and qualitative phenomenological research, data were obtained from 207 sports competition management organizations registered with the Department of Business Development in 2020. Based on in-depth interviews, a group discussion with the Council of Industry Committees was implemented to corroborate the results of the in-depth interviews. The sports industry group comprised of three individuals and two academics in sports business management who conducted a corroborative elemental analysis on the data. And structural equation models. The hypothesis research found that 1) sports resources had a direct effect on the value added of the sports industry and an indirect effect on the value added of the sports industry through the national sports competition management; 2) the sports resources had a direct effect on the national sports competition management; and 3) the national sports competition management had a direct effect on the added value of the sports industry in Thailand. The analysis revealed that the hypothetical model was consistent with the statistical data. It appeared to be qualified with χ2 = 47.85, p-value = 0.08, χ2/df = 1.55, GFI = 0.96, AGFI = 0.98, and RMSEA = 0.01. The contribution of this research is that it can explain the relationship between the causes and outcomes of sports resources and guidelines for organizing national sports events and the added value of the sports industry in Thailand. The results of the study can be used in the management of sports competition management businesses, which leads to sustainable performance for the sports industry. Doi: 10.28991/ESJ-2023-07-02-010 Full Text: PDF

Abstract

This study aims to investigate the effect of impression management on employee contextual performance in service organizations using quantitative methods. The social influence theory, which explains the role of superior influence over the subordinate, served as the theoretical underpinning for the study. A cross-sectional survey design was adopted in line with positivism research philosophy. The accessible population of this study consists of one hundred selected service-oriented firms (four-star hotels, fast food restaurants, and travel agencies) operating in the southern part of Nigeria. The sample consists of middle managers, human resource managers, front desk officers, housekeepers, and customer relationship managers. Frequency distribution was used to analyze participants’ profiles, while linear regression was employed to analyze the formulated hypotheses. Statistical Package for the Social Sciences (SPSS) 20.0 served as statistical software. Linear regression results suggest that self-promotion exerted a significant positive effect on co-worker support. Ingratiation demonstrated a significant positive effect on customer satisfaction. It appears that exemplification exerted a significant positive effect on enterprise compliance. The outcome of this study has demonstrated that traditional managerial skills can no longer hold water in contemporary service-oriented organizations because of the workplace's dynamic and changing technological structure. This study concludes that impression management can assist managers in influencing their employees positively to achieve organizational objectives. Doi: 10.28991/ESJ-2023-07-02-05 Full Text: PDF

Abstract

Business process changes occurred very often in organizations to maintain business continuity, which had an impact on information changes and process flow improvements. There are numerous companies that have problems managing data, information, and software applications, especially with the constant demands for employee information. This research objective is to integrate data and applications based on service-oriented architecture (SOA) by using the service-oriented modelling architecture (SOMA) software development method to solve the problem of producing updated and real-time information practically required by organization functions. This research result shows this implementation can help analyze the company's business model by generating information needs and service candidates that refer to SOA concepts. This implementation also gives a solid integration of in-house applications with different platforms and data sources from different databases with real time information. From a technical point of view, this implementation also reduces the duplication of business process functions and in-house application management, as well as simplifying and accelerating the creation of new or updating in-house applications related to new information requirements of the company. It was found that the SOMA framework can also be employed as a reference for companies developing future applications with SOA basics. Doi: 10.28991/ESJ-2023-07-02-011 Full Text: PDF

Abstract

Field and experimental data on aquatic ecosystem species show the effect of fear on changing prey demographics. The fear effect has an impact on aquatic ecosystems, such as species migration to settled areas. In this paper, the type of research described is a literature study. The cost effect assigned to the reproductive system of the prey population and the predation function response are given as Holling Type IV for research purposes to model the fear effect. Some research novelties, the equilibrium points are all shown in the population dynamics system model with an analysis of positive equilibrium. Positive and biologically realistic equilibrium points were analyzed using the Routh-Hurwitz criterion which is mathematically a local asymptotically stable. A pair of imaginary eigenvalues with a negative real part can increase population growth. An equilibrium region showing equilibrium for several parameters such as extinction, no predators, and two populations coexisting in a sustainable manner. The correlation and fluctuation of fear and fear cost were investigated to obtain a better model. The results of the numerical simulations show that the prey population becomes more daring to fight or fighting power with significant prey growth rates or high predator mortality rates. Doi: 10.28991/ESJ-2023-07-02-06 Full Text: PDF

Abstract

Despite the recent developments in AI, ethical questions arise when consumers contemplate how their data is being treated. This paper develops a conceptual model building on the theory of acceptance, risk, trust, and attitudes towards AI to understand the drivers that lead consumers to accept AI, considering consumers' ethical concerns. The model was empirically tested with 200 consumers of AI marketing services. The findings reveal that perceived risk significantly impacts attitudes toward AI, ethical concerns, and perceived trust and suggest a significant association between perceived risk, ethical concerns, and social norms. This research provides important theoretical and managerial implications for the ethical aspects of AI in marketing by highlighting the ethical and moral questions surrounding AI's acceptance. Doi: 10.28991/ESJ-2023-07-02-01 Full Text: PDF

Abstract

Objectives: This paper addresses the problem of secure data storage and sharing over cloud storage infrastructures. A secure, distributed cloud storage structure incorporating the blockchain structure is proposed that supports confidentiality, integrity, and availability. Methods/Analysis: The proposed structure combines two well-known technologies: one of them is the Ethereum Blockchain and its Smart Contracts and the other is the RSA encryption and authentication scheme. The Ethereum Blockchain is used as a data structure, which ensures data availability and integrity while RSA provides sensitive data confidentiality and source authentication. Findings: As a result, users of the proposed structure can trust it and be certain that they can securely exchange information through a publicly accessible and shared cloud storage. The application can be used either through a user interface (UI) or a command-line interface (CLI). Novelty /Improvement:The novelty of this work is that the system that is proposed could be used for secure data storage on the cloud as well as for file sharing and authentication verification. Also, secure data storage and file sharing are already offered by the proposed system. Doi: 10.28991/ESJ-2023-07-02-012 Full Text: PDF

Abstract

Many studies have examined the relationship between training and employee job satisfaction, the relationship between employee training and organizational commitment, the relationship between competence and employee job satisfaction, and the relationship between competence and organizational commitment, but there are still many unanswered questions. In particular, research has not explained how training and competence directly affect job satisfaction and managerial competence and how training and competence indirectly affect organizational commitment through job satisfaction. Therefore, this study investigates how training and competence directly affect job satisfaction and organizational commitment. Indirectly, training and competence affect organizational commitment through job satisfaction. Survey-based data collection was collected by purposive sampling, which included 280 employees from BPJS who participated in the training. The findings from the path analysis, along with measurements and structural tests, are very supportive of the employee training program. The findings show that employee training and competence directly affect job satisfaction and organizational commitment. The findings also show that training and employee competence indirectly affect organizational commitment through job satisfaction. Finally, employee job satisfaction affects managerial competence. This study shows that employee training is an effective way for organizations to achieve their goals. Doi: 10.28991/ESJ-2023-07-02-016 Full Text: PDF

Abstract

Nowadays, lighting planning is predominantly determined by the need to meet physically measurable requirements that are often based on current lighting standards. However, meeting the minimum technical requirements of the standards is no guarantee for a visually appealing light environment. Instead, requirements based on perceived light qualities also need to be included to achieve better user comfort. Taking perception-based qualities into consideration when creating a light environment is, for many, not an easy task. In addition, a common terminology for perceived light qualities is currently lacking, both in industry and in research. The aim of this paper is, therefore, to explore how perceived light qualities of white light sources can be described when employing user-centric measures. The focus was on the qualities of light colour and diffuse and distinct light since these qualities have a great impact on the visual impression of light. The perception was assessed by applying analytical sensory analysis to lighting products, a method found to be promising in previous work. The methodology is based on analytical measurement by the human senses, which is particularly valuable when developing a general terminology. Since sensory analysis is still quite new to the topic of lighting, the applicability of using the methodology to assess lighting in a real context was also investigated. The results of the studies showed that the perception of light qualities can be described using further concepts in addition to those currently used. For light colour, the concepts of reddish, bluish, yellowish, and greenish light colours proved suitable for providing a richer description of the quality. The concepts of diffuse and distinct light satisfactorily captured variations in light contrast produced by shadows, reflections, and sparkles. In addition, the studies revealed that analytical sensory analysis was applicable for assessing the perception of lighting in a real-world context. The latter means that knowledge gained in the laboratory can be translated into real environments. The user-centric measures investigated in this paper have contributed to the terminology related to perceived light qualities. These can complement the physical measures in lighting planning to promote light environments that are not only energy efficient and meet technical requirements, but also cater for increased user comfort. Doi: 10.28991/ESJ-2023-07-02-022 Full Text: PDF

Abstract

This paper seeks to analyze how and why divergent institutional changes occurred in a government agency. While there is evidence of research on the concept of collective action and involvement in the literature on institutional entrepreneurship, the focus has been at the macro and field levels, with scarce attention being given to the topic at the micro and organizational levels. This study addresses this gap in the literature, drawing on the institutional entrepreneurship process model of Battilana, Leca, and Boxenbaum (The Academy of Management Annals), in combination with literature on collective action. The methodology involved a longitudinal case study, in which data were collected through extensive interviews and documentation analysis. Based on findings showing that the divergence change process could not be achieved without the support of organizational collective involvement, a refined version of the Battilana et al. entrepreneurial model is proposed. Doi: 10.28991/ESJ-2023-07-02-017 Full Text: PDF
