Identifying the flow regime is a prerequisite for accurately modeling two-phase flow. This paper aims to introduce a comprehensive data-driven workflow for flow regime identification.

A numerical two-phase flow model was validated against experimental data and was used to generate dynamic pressure signals for three different flow regimes. First, four distinct methods were used for feature extraction: discrete wavelet transform (DWT), empirical mode decomposition, power spectral density and the time series analysis method. Kernel Fisher discriminant analysis (KFDA) was used to simultaneously perform dimensionality reduction and machine learning (ML) classification for each set of features. Finally, the Shapley additive explanations (SHAP) method was applied to make the workflow explainable.

The results highlighted that the DWT + KFDA method exhibited the highest testing and training accuracy at 95.2% and 88.8%, respectively. Results also include a virtual flow regime map to facilitate the visualization of features in two dimension. Finally, SHAP analysis showed that minimum and maximum values extracted at the fourth and second signal decomposition levels of DWT are the best flow-distinguishing features.

This workflow can be applied to opaque pipes fitted with pressure sensors to achieve flow assurance and automatic monitoring of two-phase flow occurring in many process industries.

This paper presents a novel flow regime identification method by fusing dynamic pressure measurements with ML techniques. The authors’ novel DWT + KFDA method demonstrates superior performance for flow regime identification with explainability.

Our paper studies a central issue with a long history in economics: the relationship between population and economic growth. We analyze the joint dynamics of economic and demographic growth in 111 countries during the period 1960–2019.

Using the concept of economic regime, the paper introduces the notion of distance between the dynamical paths of different countries. Then, a minimal spanning tree (MST) and a hierarchical tree (HT) are constructed to detect groups of countries sharing similar dynamic performance.

The methodology confirms the existence of three country clubs, each of which exhibits a different dynamic behavior pattern. The analysis also shows that the clusters clearly differ with respect to the evolution of other fundamental variables not previously considered [gross domestic product (GDP) per capita, human capital and life expectancy, among others].

Our results indirectly suggest the existence of dynamic interdependence in the trajectories of economic growth and population change between countries. It also provides evidence against single-model approaches to explain the interdependence between demographic change and economic growth.

We introduce a methodology that allows for a model-free topological and hierarchical description of the interplay between economic growth and population.

Start-ups are successful in receiving valuation in billions of US dollars prior to initial public offering (IPO). However, to sustain higher valuation, the stocks need to perform consistently after the IPO. Short-run stock performance of India-based start-ups during the first year of IPO listing from March 2021 to March 2022 is analysed.

The paper deals with the new generation start-ups' stock performance in emerging market in terms of total and abnormal return generated in comparison to the market (NIFTY-200). Further, the volatility of returns during bear and bull regimes is analysed through a family of Markov-switching GARCH models using both normal and skewed distributions.

The results suggest that start-up stocks are more volatile during bear regime than in the bull run in market-based economies where price limit policy does not apply. Besides, the cumulative abnormal return over the market return was lower for majority of start-up IPO stocks.

Though negative returns of the start-up stocks during the first year of IPO need not be surprising, higher volatility during bear regime is a matter of concern as it could severely impact retail investors and founders. The results hold implication for IPO regulation in emerging markets and for retail investors desirous of investing in start-up stocks.

Volatility of return is examined using a state-space model during the first year of the start-up IPO listing. The study contributes to the emerging market IPO literature by examining IPO performance in market-based economy. Previous IPO performance studies in emerging markets are predominantly based on ecosystems where start-ups are subjected to price limit policy, and it does not reflect the true nature of IPO performance across emerging markets.

The purpose of this paper is to discuss how agency conflicts between people and main government organs affect the combatting ability of white-collar money laundering in an emerging economy.

This paper uses a qualitative design under the philosophy of interpretivism. The case study research strategy is used inductively to investigate how structural limitations affect white-collar money laundering.

This study reveals that serious agency conflicts exist between public and main government organs which are detrimental to the rights of people to enjoy a crime-free society. First agency conflict of people and legislature intensifies as a result of limited understanding of the legislature and failure to take precautionary actions to develop an anti-money laundering and countering the financing of terrorism (AML/CFT) regime with evolving global standards. This delay has resulted in identifying Sri Lanka as a deficient AML/CFT regime twice. The second conflicts arise between people and the executive which is a serious conflict due to misuse of statutory power and failure to perform duties. The independence and integrity of administrative authorities who perform executive functions were inherent problems of implementing a sound AML/CFT regime. Lack of monitoring, nonavailability of an independent audit and inappropriate reporting channels were other encouraging factors of administrative organs to misuse statutory power. The third conflict between people and the judiciary was not intensified because the function was not so exposed to create agency conflicts. After all, an adequate number of cases had not proceeded to the judiciary due to inherent limitations as a result of intensified first two agency conflicts. The agency conflicts have intensified over the years and AML/CFT regime has been ineffective as a result of limited influence and understanding of the principal, people. Therefore, the principal has to influence the agents to make reforms in the AML/CFT regime to make the country a white-collar crime-free country.

This study uses a case study strategy to assess the context of Sri Lanka as an emerging economy. It is recommended to take into consideration the contextual facts when the findings are applied to other jurisdictions.

This paper is an original work of the authors which discusses how agency conflicts arise between people and three main government organs in implementing a sound AML/CFT regime in Sri Lanka as an emerging economy.

This study aims to investigate the effect of national culture (power distance, individualism, masculinity, uncertainty avoidance and long-term orientation) on audit report lag.

The authors use two econometric approaches (ordinary least squares (OLS) and quantile regression) using STATA software for a sample of 1,208 firm-year observations over the period of 2017–2018.

Using Hofstede’s (2001) cultural dimensions (power distance, individualism, masculinity, uncertainty avoidance and long-term orientation), the authors find that masculinity and long-term orientation are positively associated with audit report lag, while uncertainty avoidance is negatively associated with the same variable. Quantile regressions suggest that the adverse effect of masculinity on audit report lag is more prevailing for companies communicating companies' annual reports in a timely manner. Furthermore, the positive association between power distance and audit report lag exists only under tardy disclosure regime. Quantile regressions also confirm that the negative (positive) effect of uncertainty avoidance (long-term orientation) on audit report lag is maintained under different timely disclosure regime. Additional analysis conducted with respect to legal system shows that individualism becomes a significant predictor of audit delays with a significant negative effect for common law countries, while uncertainty avoidance has a positive effect on the same variable in civil law countries characterized by high level of discretion and secrecy.

The results of this study suggest that national culture as an informal institution may complement formal institutions (e.g. financial markets) in promoting timely disclosure. For instance, foreign investors may view high uncertainty avoidance scores, in common law emerging economies, as an indicator of transparency and timely disclosure.

This study adds to the extant literature a further understanding of the impact of cultural dimensions on timely disclosure, as proxied by, audit report lag. The use of quantile regression approach shows how different timely disclosure regime may affect the association between masculinity, power distance and audit report lag.

The purpose of this study is to investigate the nonlinear effects of renewable energy (RE) consumption and economic growth on per capita CO₂ emissions during the time span from 1980 to 2020.

The study uses the logistic smooth transition autoregression (STAR) model to decipher the nonlinear relationship between RE consumption, economic growth and CO₂ emissions in the Indian economy.

The estimated results confirm a nonlinear relationship between India’s economic growth, RE consumption and CO₂ emissions. The authors found that economic growth positively impacts CO₂ emissions until it reaches a specific threshold of 1.81 (per capita growth). Beyond this point, further economic growth leads to a reduction in CO₂ emissions. Similarly, RE consumption positively affects CO₂ emissions until economic growth reaches the same threshold level, after which an increase in RE consumption negatively impacts CO₂ emissions.

The study suggests that India should optimize the balance between economic growth and RE consumption to mitigate CO₂ emissions. Policymakers should prioritize the adoption of RE during the early stages of economic growth. As economic growth reaches the specific threshold of 1.81 per capita, the economy should shift to more sustainable and energy-efficient practices to limit the effect of further CO₂ emissions on further economic growth.

To the best of the authors’ knowledge, this study represents the first-ever endeavor to reexamine the nonlinear relationship between RE consumption, economic growth and CO₂ emissions in India, using the STAR model.

This study investigated the moderating role of democracy in the relationship between corruption and foreign direct investment. The purpose of this study is to understand whether corruption has different effects on the location decisions of multinational enterprises (MNEs) depending on the regime type.

This study explored how institutional context influenced the impacts of corruption on the location decisions of MNEs, specifically using a sample of Chinese cross-border mergers and acquisitions between 2000 and 2020.

This study assessed the role of democracy in the relationship between corruption and the location decisions of Chinese MNEs. In general, this study found that Chinese MNEs were hindered by host country corruption, but that these detrimental effects were weaker in the presence of more effective democratic institutions.

This study contributes to the literature on institutional factors in international business through its simultaneous investigation of the effects of both democracy and corruption on the location decisions of MNEs. Moreover, there is a prevailing view that Chinese MNEs are willing to enter countries with high corruption, but the results of this study indicate that they are risk-averse in ways similar to their Western counterparts.

This study aims to examine the link between boards and audit committees and firm performance in Kuwaiti listed firms in the context of recent and extensive corporate governance regulatory reform.

Panel data regression analysis with fixed effects and clustered standard errors of firm performance for 61–97 listed industrial and services firms in Kuwait over a seven-year period. The dependent variables are the returns on assets and equity, the debt-to-equity ratio and leverage and Tobin’s Q and the independent variables comprise board of directors and audit committee characteristics, including size, the number of meetings and the numbers of independent and outside board and expert committee members. Firm size, subsidiary status and cash flow serve as control variables.

Mixed results with respect to the characteristics of the board of directors. Board size and independent and outsider board members positively relate only to Tobin’s Q and insiders only to debt to equity. For audit committee characteristics, committee size, independence and expertise positively relate to the return on equity and committee size and expertise only to Tobin’s Q. Of the five performance measures considered, board and audit committee characteristics together best determine Tobin’s Q.

Data from a single country limits generalisability and control variables necessarily limited in a developing market context. Need for qualitative insights into corporate governance reform as a complement to conventional quantitative analysis. In combining accounting and market information, Tobin’s Q appears best able to recognise the performance benefits of good corporate governance in terms of internal organisational change.

The recent corporate governance code and guidelines reforms exert a mixed impact on firm performance, with audit committees, not boards, of most influence. But recent reforms implied most change to boards of directors. One suggestion is that non-market reform may have been unneeded given existing market pressure on listed firms and firms anticipating regulatory change.

Kuwait’s corporate governance reforms codified corporate governance practices already in place among many of its firms in pursuit of organisational legitimacy, and while invoking substantial change to audit committees, involved minor change to firm performance, at least in the short term. Some firms may also have delisted in expectation of stronger corporate governance requirements. Regardless, these direct and indirect processes both improved the overall quality of listed firm corporate governance and performance in Kuwait.

Seminal analysis of corporate governance reforms in Kuwait, which have rapidly progressed from no corporate governance code and guidelines to an initially voluntary and then compulsory regime. Only known analysis to incorporate both board of directors and audit committee characteristics. Reveals studies of the corporate governance–firm performance relationship may face difficulty in model specification, and empirical significance, given the complexity of corporate governance codes and guidelines, leads in changing firm behaviour and self-selection of firms into and out of regulated markets.

The world is experiencing democratic backsliding such that the situation is down back to 1986. This has resulted in the global shrinking of civic space for civil society organizations (CSOs). NGOs engaging in advocacy activities are seen to be among the CSOs affected. Using four NGOs cases from Tanzania, the study contributes to the civic space debate by uncovering how advocacy NGOs become resilient.

The study is anchored in interpretivism and a cross-sectional case study design, following a qualitative approach path. Data were collected through interviews and a documentary review.

Results show that several strategies such as complying, building community back-up, collaboration, strategic litigation, using digital media and changing the scope are applied. However, strategies face obstacles including scope limitations, expected democratic roles, high cost, changes in the scope and being outsmarted by the government, and hence their effectiveness is questionable.

This study focused on advocacy NGOs. More studies can be conducted for other advocacy-related CSOs on how they become resilient.

While NGOs are allowed to exist in the country, their freedom continue to be curtailed. Even the effectiveness of resiliency becomes temporary and depends on the political will of the existing regime.

Tanzania NGOs have to build strong bonds with citizens, expand the scope of strategies and use deliberative democratic principles to educate the government to change laws and tolerate plural political culture. Also, NGOs in other countries with confined civic space can apply the same.

The purpose of this paper is to find out the possible gaps in the Sharīʿah governance, and suggest how to fill the same, in line with the principles of Islamic finance and the global developments regarding social and value-based financial intermediation.

The paper uses secondary data gathered through analysis of documents and regulations to portray the current Sharīʿah governance framework and to suggest a unique paradigm to be adopted by the regulators of Islamic financial institutions.

The paradigm encompassing value-oriented financial ecosystem would need a comprehensive set of discipline, accountability and governance for making the pursuit of sustainable development goals and corporate social responsibilities effective in a well-defined schedule prepared and implemented by the regulators.

The scope of this research is limited to theory building in the light of emerging trends in responsible and social finance. It is not to empirically test the impact of the governance framework in terms of social justice, corporate responsibility and sustainability.

It would help the policy makers, regulators, researchers and the practitioners in finance to align banking and finance with social and environmental responsibility, and equity through governance and accountability for realizing the sustainable development goals.

It links the regulatory approaches to the emerging paradigm and ecosystem comprising sustainability and value-based governance, awareness and corporate social responsibility.

The paper adds value to the current regulatory frameworks enabling the Islamic financial institutions to realize the economic, social and sustainability objectives, in addition to Shariah legitimacy and enhanced credibility.
