Conventional study on the trading pattern of investors is either done in the viewpoint of the identity of investors or analyzed on the base of investor's type, which is categorized according to the number of transactions using only restricted security company data. Dataset in this paper is extended to all ELW series and investor's type such as the LP (Liquidity Provider). High-frequency traders are categorized on the base of average number of transactions per day and average trading volume per day. We analyze their trading pattern and relationship between P/L (profit and loss) and their trading pattern. Also We develop a new measurement tool, called the holding period, to comprehend the characteristic of high frequency trading and analyze the effect of holding period on P/L of investors.

Our empirical investigation shows that, for general investors, 1) their counterparties are LP during the execution of buy low and sell high trading strategy, 2) they lose in the cumulative P/L for the intermediate transaction although their average sell price is more expensive than average buy price, 3) due to the lack of risk management technique such as stop loss, they lose in the cumulative intermediate transaction P/L although their winning ratio is higher than losing ratio. On the other hand, 1) scalpers are mainly engaged in trading index ELW market, 2) due to the appropriate execution of stop loss, they win in the cumulative P/L for the intermediate transaction although their draw ratio and trading unit price are high. Meanwhile, due to the LP's passive characteristic for the buying execution after selling, their draw ratio is very low and their buy unit price is higher than sell unit price in comparison to other investor type, and their trading pattern is negatively related to that of the other investor type. Finally we confirm that the holding period is a significant impact on P/L of general investors and scalper.

As a policy proposal, it is necessary to introduce a market maker system in the individual stock options market for activating the stock options market, which has a more competitive market structure than ELW market. In the viewpoint of financial consumer protection, education on the time value reduction of contingent claim derivatives with finite maturity is necessary.

Container liner shipping companies started expanding their business by investing in container port terminals in the late 1990s. This market entry results in an extensive presence of vertically integrated liners and terminals. This study aims to explore the competition effects of this vertical integration trend based on a regional (European) analysis. In particular, it extracts lessons from the European Commission (EC) cases on the competition effects of vertical integration. The critical analysis of the cases examined at the institutional level intends to reach conclusions on whether liner–terminal vertical integration harmed or advanced competition in the relevant markets and/or the extent that there is a need to revise the current policy practices.

This study critically assesses the EC’s decisional practices in port container terminal vertical mergers in the last 25 years (1997–2021). Based on a literature review comparing maritime and competition economists' perspectives, it reviews the types of mergers examined, the methodology followed for relevant market definition and calculation of market shares and the estimated competition effects. The Hamburg–Le Havre area is the port range used as a case study for comparing the decisional practice with actual market developments. These container ports serve the greatest consuming market of final and intermediate goods in Europe and are gateways to Central and Eastern Europe.

The assessment identifies a need for expanding the investigation as a precondition for reaching conclusions on both the anti- and pro-competitive effects. First, only a limited number of transactions have been notified to the EC. Second, the empirical research identified a gap in this process, as there were no decisions (phase I) on vertical mergers between 2008 and 2016. Third, the exante assessment has not applied a phase II in-depth analysis to any case due to the absence of competition concerns. Finally, due to the absence of complaints, there is a lack of any ex post assessment of the effects of vertical integration.

This assessment is important for understanding the current and emerging features of intra-port and inter-port competition and the potential effects that the continuation and expansion of liner companies' vertical integration strategies will have along maritime supply chains. It also contributes to the broader discussion on liner companies' strategies, such as the research and policy-making efforts around the globe to understand the impact of both vertical and horizontal integration.

These discussions are critical for a diversity of businesses that use liner shipping services or provide facilities and services to container shipping lines or ports. They are important for the interests of customers and consumers as they could inform any needed re-visiting of competition policy to protect from the dominance of any market developments that would lead to conditions limiting competition. Expanding analysis on the competition effects of non-notified mergers would help a better understanding of market changes.

Enhancing competition and limiting monopolies is valuable from a consumer's perspective. This is more so in the case of maritime trade that serves the needs of societies. The study contributes by generating a better understanding of how decision-makers have worked towards that direction and what realignments are worthy.

There are no previous comprehensive reviews and analyses of the ways that policy-makers at the regional level have addressed the competition effects of vertical integration strategies of liner shipping companies when enhancing competition is valuable from a consumer perspective. Comparing maritime economists and competition, the study, via its literature review, also offers a comparison of maritime and competition perspectives on these competition effects, allowing positioning of how effective decisional-making practices have been.

The study, by focusing on a context dominated by firms with a concentrated ownership, in which type-II agency problems (principal-principal conflicts) may occur, aims to depict which board configurations may be effective in protecting minority shareholders by mitigating the risk of controlling shareholders' expropriation via cash holdings.

The research adopts a configurational approach and empirically conducts a fuzzy set/qualitative comparative analysis on a sample of 268 Italian listed companies.

The analysis depicts three combinations of board configurations and ownership structures that can be considered effective, namely Active Independent Control, Female Active Control and Double Internal Control.

The study revisits the topic of the risk of expropriation via cash holdings in a type-II agency problem framework and delineates the meaning of board effectiveness in a mature context ruled by family firms, like Italy. Furthermore, by drawing on a configurational approach, it overcomes the causality relationship between each board characteristic and cash holdings policies and reasons from a “bundle” perspective.

The purpose of this paper is to explore how sustainability reporting is shaped by the global influences and particular national context where businesses operate.

The paper uses both content analysis of published sustainability information and semi-structured interviews with corporate managers to explore how sustainability reporting is used to address unique social and environmental challenges in a developing country – Sri Lanka. The use of integrative social contracts theory in investigating sustainability reporting offers novel insights into understanding the drivers for sustainability reporting practices in this particular country.

The findings reveal that managers’ perceptions about usefulness of sustainability reporting, local contextual challenges and global norms influence the extent to which companies engage in sustainability reporting and the nature of sustainability information reported. In particular, Sri Lankan company managers strive to undertake sustainability projects that are beneficial not only to their companies but also to the development of the country. However, while company managers in Sri Lanka are keen to undertake sustainability reporting, they face different tensions/expectations between global expectations and local contextual factors when undertaking sustainability projects and reporting. This is also showcased in what is ultimately reported in company annual reports, where some aspects of sustainability, e.g. social, tend to focus more on addressing local concerns whereas other disclosures are on issues that may be relevant across many contexts.

Important insights for government and other regulatory authorities can be drawn from the findings of this study. By capitalising on the strong sense of moral duty felt by company managers, policymakers can involve the business sector more to mitigate the social and environmental issues prevalent in Sri Lanka. The findings can also be used by other developing countries to enable pathways to engage with the corporate sector to contribute to national development agendas through their sustainability initiatives and projects.

While the usual understanding of developing country’s company managers is that they try to follow global trends, in Sri Lanka, this research shows how managers are trying to align their responsibilities at a national level with global principles regarding sustainability reporting. Therefore, this paper highlights how both hypernorms and microsocial rules can interact to define how company managers undertake sustainability reporting in a developing country.

The authors investigate the effect of a short-term stock return reversal on the term structure of momentum profits in the Korean stock market following Goyal and Wahal (2015). Their empirical findings show that the term structure of momentum is more pronounced when a return reversal lasts up to two months but is substantially weakened when past performance over the last two months is not taken into account for portfolio formation. Their evidence suggests that the term structure of momentum profitability arises primarily from a carryover of the return reversal from the previous two months.

The purpose of this paper is as follows: First, understanding the nature of the relationship between corporate adoption of the concept of societal responsibility [availability of environmental awareness, clear vision of the impact of societal responsibility on financial performance, managers informing employees of the latest developments in societal responsibility programs, managers' response to their corporate social responsibility (CSR) proposals] in the form of an annual report that supports the success of the company's objectives, the company's management encourages employees to participate collectively in societal responsibility programs and to protect the environment from pollution in the petrochemical industry. Second, understand the nature of the relationship between the dimensions of corporate social responsibility concept (cultural, social, economic, ethical and legal) and protect the environment from pollution in the petrochemical industry. Third, the research also seeks to show the role of societal responsibility and its application in the petrochemical companies to protect the environment from pollution in The Governorate of Alexandria – Egypt, and come out with results and recommendations that could help protect the environment from the forms of environmental pollution resulting from the production processes of this industry.

The researcher has relied on each of the following approaches: Case study methodology is a research strategy aimed at solving a problem or facing a particular situation. It is based on preliminary hypotheses through full analysis of all data collected and recorded. Which depends on the study of a limited number of cases or vocabulary in-depth comprehensive study through the study of all or a large number of variables overlapping and interrelated and influential on the problem under consideration. Thus, it provides a deep and rich understanding of what is going on around the research and the processes that are related to it, and not only the external or apparent description of the situation or phenomenon; it cares about the total description and looks at the particles, in relation to the whole. Quantitative approach: by giving a numerical description indicating the size or size of the phenomenon or the degree of association with the phenomenon. Other phenomena. Accordingly, the role of the petrochemical companies in Alexandria Governorate, and the social responsibility programs carried out within the governorate in terms of importance, growth and requirements, and the most important characteristics and constraints and components and methods of work and developments have been described. Thus, the researcher can analyze the relationship between CSR and environmental protection from pollution in Alexandria Governorate.

There is paucity in the studies that dealt with the relationship between CSR and environmental protection against pollution in public organizations. There is agreement among the sample on the importance and feasibility of adopting the concept of social responsibility and placing it at the top of the top management concerns, especially in the field of petrochemical companies. With the need to take concrete implementation measures to support social responsibility programs aimed at serving the community among all stakeholders. The effective implementation of the mechanisms for the implementation of meaningful social responsibility programs requires fundamental changes in management practices, existing organizational structures and the quality of personnel working in the relevant departments, in general, and the social responsibility group, in particular, which may be difficult for political and economic reasons.

Time: The study period was set from 2015 to 2017. Place: The study focuses on the petrochemical companies operating in Alexandria. Humanity: The study focuses on the employees of the petrochemical companies operating in Alexandria Governorate.

The adoption of social responsibility positively affects the protection of the environment from pollution, and this effect shows that the adoption of the concept of corporate social responsibility is influenced by the following factors: increasing the participation of workers with healthy environmental contributions to the productive process; increasing the companies' economic and social activities toward protecting the environment from pollution; increasing the capacity of companies to pay greater costs to preserve the environment; increasing the awareness of green consumers with the products it offers Companies; development of continuous internal work environment companies; and clearly defined strategy followed in social responsibility programs.

The social responsibility of the public organizations derives their strength through, first, the keenness of these organizations to analyze the variables of the ethical dimension of social responsibility and their availability, which will lead the organizations to provide their services with the highest quality and sincerity. That this analysis (ethics of individuals) as training members of the social responsibility team to solve problems using brainstorming and provide employees with official data related to improving work (ethics of leadership), such as the identification of business objectives through the participation of managers with subordinates, and the punishment of workers who exhibit immoral behaviors (ethics of productive processes) as a decision-making process to ethical standards regardless of the costs involved. When there is an immoral behavior and managers are responsible for implementing the changes needed to reach the targeted outcomes), second, promote partnerships with other relevant sectors for community service.

According to the results of the previous studies and the applied study results, the researcher would like to submit a mechanism to the directors and heads of the boards of directors of the Egyptian petrochemical companies under study.

The purpose of this study was to investigate the factors impacting the intermediating variable of employee engagement toward employee performance in a hybrid working organization in Bangkok, Thailand.

This study uses secondary data analysis and an archival study; the primary data were gathered from 370 employees who are working in a hybrid model environment in a private agricultural machinery company. To construct a new conceptual framework, this study adopted four frameworks from the previous research.

Perceived organizational support and trust and respect in the organization are found to have a significant positive impact on employee engagement. Moreover, there is a significant positive impact of the employee engagement on employee performance in a hybrid working model.

For hybrid work environments, the research focused mainly on the emotional themes of perceived support, trust and respect in the organization. Therefore, there would be many factors that could possibly affect those dependence variables in any environment, which will have to be investigated more in future research. Either in the organization or in the company, many departments and business units operates for the company, but the researcher specifies only the business units or departments that now use the hybrid working model.

This study focuses on a case study of an agricultural machinery company, which likely produces different results than other industries, other industries may produce different results.

Hybrid working models can blur the boundaries between work and personal life, potentially leading to increased stress and burnout. Organizations should prioritize work-life balance and employee well-being by promoting flexible schedules, encouraging breaks and time off, and providing resources for mental health support.

The organization which is operating among a hybrid working model, the increasing of perceived organizational support and trust and respect level, has positively increase the employee engagement toward enhancing the employee performance.
