Abstract
Purpose
Using data on 739 banks from 22 countries with a dual banking system from 2012 to 2019, this paper aims to examine whether capital inflows affect banks’ profitability in recipient countries.
Design/methodology/approach
The authors check the conjecture about the effect of capital inflows on the profitability of the host country’s banks by estimating the following regression:
where the dependent variable (Pict) refers to bank profitability, measured by either ROA or ROE for bank i, country c and year t. ROA is defined as the ratio of net profit to average total assets expressed as a percentage, which determines how efficiently a bank uses its assets to generate a profit. ROE is defined as the ratio of net profit to average total equity expressed as a percentage, which is a measure of increases in shareholders’ wealth.
Findings
The authors find that capital inflows are generally positively associated with bank profitability. However, cross-border capital inflows reduce the rate of return in Islamic banks relative to their conventional counterparts. When decomposing inflows by instrument, the authors find that the enhancing role of capital inflows on bank profitability comes mainly from debt inflows and borrowers; the authors observe that the documented results emanate mostly from the inflows to the financial sector. These results remain unchanged if holding a bank’s risk constant. Overall, foreign funds in the form of debt inflows targeting the financial sector can disproportionately improve the performance of commercial banks in recipient countries.
Originality/value
The paper is an original research project. The analysis contributes to the existing literature in several ways: the authors study whether the impact of capital inflows on bank profitability varies with the bank business model by looking at both the Islamic and conventional bank systems. The profitability of the banking system is an important catalyst for growth and stability. The authors also decompose capital inflows to recipient countries into their equity and debt components and study the differential impact of those components on the profitability of Islamic and conventional banks.

Abstract
The dyeing of acrylic fabrics using C.I. Astrazon Basic Golden Yellow GLE is studied with both conventional (CH) and ultrasonic (US) techniques. The factors that affect dyeability, such as dye bath pH, US power, dyeing time and temperature, are studied. The colour strength values obtained are found to be higher with US than CH heating. Also, the fastness properties of the dyed fabrics are determined with. A comparative study using x-ray and scanning electron microscope (SEM) that is implemented on samples to explain for the better dyeability of acrylic fabrics with the US method. Dyeing kinetics and the time/dye-uptake isotherms reveal enhanced dye-uptake in the second phase of dyeing. The values of the dyeing rate constant, half-time of dyeing and standard affinity, and US efficiency are calculated and discussed.

Abstract
Wool yarns are dyed with natural colouring matter that is extracted from cochineal, turmeric and madder, and mordanted with different mordants by using the exhaustion method. Many measurements of mordanted dyed wool samples have been carried out after exposure to air and light for different periods of time in the time frame of one year in an urban area (Helwan city). The variables that are measured include changes in colour and physical properties (tensile strength, tenacity and elongation) of mordanted dyed wool samples. Also, air pollution in Helwan city is determined by studying suspended and deposited particulate matter and sulpher dioxide concentrations.

Abstract
Enzymatic treatment of jute fabrics with neutral cellulase enzymes is investigated systematically. The factors affecting enzymatic treatment including, time, liquor ratio, temperature and enzyme concentration are also examined. The hydrolyzed pretreated surfaces of jute fabrics were characterized by scanning electron microscope (SEM), weight loss (WL) and wettability (Wet) tests. WL% and Wet were found to increase as the time, temperature and cellulase concentration increased. SEM images showed that the surface of the treated fabrics was smoother and more polished than that of the untreated fabrics after being subject to optimal treatment conditions.
In contrast, rough surface, fibrillation, surface pilling and multicellular were observed in the images of the untreated fabrics. The dyeing behavior of both untreated and enzymatically treated jute fabrics with reactive dyes was also evaluated under different dyebath conditions. The measured exhaustion and fixation percent showed a significant enhancement of the dyeability of biopolished pretreated fabrics compared to untreated fabrics. The results of fastness properties also indicate good washing, perspiration and rubbing fastness.

Abstract
Purpose
Peanut skins are an agro-waste product with no commercial value. The purpose of this paper is to evaluate peanut skin as a natural dyestuff and to determine if this natural dye could be used in the dyeing of some Egyptian cotton cultivars.
Design/methodology/approach
The methodology consists of several steps; dye extraction procedure from peanut skin through aqueous extraction, then dyeing optimized using simultaneous mordanting using alum. Finally, dyed cotton has been subjected to different textile laboratory tests, for example, color measurements and mechanical properties. Color-fastness was determined on Egyptian cotton fabric. The peanut skin as a source of natural dye and the dyed cotton sample were characterized by fourier transform infrared spectroscopy (FTIR) analysis.
Findings
It was found that the natural dye extracted from peanut skin has an affinity for cotton samples and showed high dyeability with a unique color shade, good color strength and very good fastness.
Originality/value
The novelty of this paper is the extraction of color from the peanut's outer skin which is discarded as waste such as agro-waste of the agricultural process which can be used as a natural dye in the textile industry and applied to dyeing some Egyptian cotton fibers from different genotypes.

Abstract
Purpose
Sustainable development hinges on a crucial shift to renewable energy, which is essential in the fight against global warming and climate change. This study explores the relationships between artificial intelligence (AI), fuel, green stocks, geopolitical risk, and Ethereum energy consumption (ETH) in an era of rapid technological advancement and growing environmental concerns.
Design/methodology/approach
This research stands at the forefront of interdisciplinary research and forges a path toward a comprehensive understanding of the intricate dynamics governing green sustainability investments. These objectives have been fulfilled by implementing the innovative quantile time-frequency connectedness approach in conjunction with geopolitical and climate considerations.
Findings
Our findings highlight coal market dominance and Ethereum energy consumption as critical short- and long-term market volatility sources. Additionally, geopolitical risks and Ethereum energy consumption significantly contribute to volatility. Long-term factors are the primary drivers of directional volatility spillover, impacting green stocks and energy assets over extended periods. Additionally, SHapley Additive exPlanations (SHAP) findings corroborate the quantile time-frequency connectedness outcomes.
Research limitations/implications
This study highlights the critical importance of transitioning to sustainable energy sources and embracing digital finance in fostering green sustainability investments, illuminating their roles in shaping market dynamics, influencing geopolitics and ensuring the long-term sustainability required to combat climate change effectively.
Practical implications
The study offers practical sustainability implications by informing green investment choices, strengthening risk management strategies, encouraging interdisciplinary cooperation and fostering digital finance innovations to promote sustainable practices.
Originality/value
The implementation of the quantile time-frequency connectedness approach, in line with considering geopolitical and climate factors, marks the originality of this paper. This approach allows for a dynamic analysis of connectedness across different distribution quantiles, providing a deeper understanding of variable interactions under varying market conditions.

Abstract
Purpose
This paper aims to investigate the sentiment connectedness among 10 European stock markets between January 2020 and July 2022, associating such connectedness with the level of the geopolitical risk index.
Design/methodology/approach
For this purpose, a time-varying parameter vector autoregressive connectedness framework is used.
Findings
Results show a high degree of sentiment connectedness. Overall, the sentiments of Portugal, France, the Netherlands, Spain, Germany and Italy are net transmitters of shocks while those of Poland, Sweden, Norway and Romania are net receivers. Additional evidence indicates that when geopolitical risks increase, the sentiment connectedness tends to decrease. However, the reverse holds under extremely high levels of geopolitical risks.
Originality/value
Overall, this study provides some significant contributions to the literature. First, to the best of the authors’ knowledge, this is among the first few studies to examine the dynamic connectedness among stock market sentiment across countries. This issue needs special consideration for European countries because of their close geographical distance and strong integration due to the European Union’s co-development strategies. Second, the association of sentiment connectedness with geopolitical risk is examined for the first time. This is even more meaningful in the context of growing geopolitical risks stemming from the Ukraine war, which could affect international financial markets.

Abstract
This chapter relies on comparative case analysis to examine how and why particular social entrepreneurs in a higher Asian middle income economy broke new grounds in private higher education. The study provides arguments as to why these private higher education entrepreneurs, when viewed inclusively, are social entrepreneurs. Findings from the study suggest that social entrepreneurs distinctively used prior insights from their working experiences to harness the financial power of local capital to fund the scaling up of their social ventures while simultaneously engaging with the country’s economic and social challenges.

Abstract
Purpose
Internationalization and financial deregulation have caused market participants and policymakers to consider the significance of financial connectedness and the spillover effects of shocks. In this context, this research is a pioneering effort to investigate the direction and magnitude of return volatility spillovers between Pakistan’s financial markets and those of its key trade partners. This paper examines the relationship between return and volatility spillover in the financial markets of Pakistan and its major trading partners.
Design/methodology/approach
Ten countries are selected for empirical examination of dynamic connectedness among Pakistan and its major trading partner’s stock markets. This study utilizes a spillover index approach model and considers daily, weekly and monthly datasets spanning 25 years from 1995 to 2019.
Findings
The results indicate that stock markets provide efficient channels for return and volatility spillovers. Moreover, it is found that the intensity of spillovers during the financial crisis is more intense as these crises are major determinants of contagion; consequently, investors, speculators and policymakers use these events for their respective purposes.
Originality/value
Researchers, practitioners, policymakers and investors may all benefit from the findings in areas including risk management, portfolio diversification and trading methods.

Abstract
This study combines perceived knowledge, perceived psychologic risk with Theory of Planned Behaviour (TPB) to examine the influence on tourists' intention to choose a safe destination and willingness to pay (WTP) more for safety measures. An online survey was conducted in 2021 to approach tourists globally. After 10 weeks, we received 365 valid responses. SmartPLS software version 3.3 was applied to run structural equation modelling to test the proposed hypotheses. Research results reveal that intention to choose a safe destination mediates the relationship between perceived knowledge of COVID-19, perceived psychological risk and the WTP more for safety measures while moderating role of educational level is also addressed. In turn, perceived psychological risk mediates the relationship between perceived knowledge of COVID-19 and intention to choose a safe destination. As a result, this study implies that destination managers should take actions to promote their WTP more for safety measures.
