Assistive technology has been developed to assist the visually impaired individuals in their social interactions. Specifically designed to enhance communication skills, facilitate social engagement and improve the overall quality of life, conversational assistive technologies include speech recognition APIs, text-to-speech APIs and various communication tools that are real. Enable real-time interaction. Using natural language processing (NLP) and machine learning algorithms, the technology analyzes spoken language and provides appropriate responses, offering an immersive experience through voice commands, audio feedback and vibration alerts.

These technologies have demonstrated their ability to promote self-confidence and self-reliance in visually impaired individuals during social interactions. Moreover, they promise to improve social competence and foster better relationships. In short, assistive technology in conversation stands as a promising tool that empowers the visually impaired individuals, elevating the quality of their social engagement.

The main benefit of assistive communication technology is that it will help visually impaired people overcome communication barriers in social contexts. This technology helps them communicate effectively with acquaintances, family, co-workers and even strangers in public places. By enabling smoother and more natural communication, it works to reduce feelings of isolation and increase overall quality of life.

Research findings include successful activity recognition, aligning with activities on which the VGG-16 model was trained, such as hugging, shaking hands, talking, walking, waving and more. The originality of this study lies in its approach to address the challenges faced by the visually impaired individuals in their social interactions through modern technology. Research adds to the body of knowledge in the area of assistive technologies, which contribute to the empowerment and social inclusion of the visually impaired individuals.

This paper aims to examine the dynamic relationship among energy efficiency, health expenditure and economic growth in Malaysia over the sample period of 1980–2016.

This study uses autoregressive distributed lag cointegration analysis and the causality approach by the vector error correction model to analyse the relationship among energy efficiency, which is proxied by energy intensity and the determinant factors.

The findings of this paper suggest long-run cointegration causal links between economic growth and health expenditure. However, a mixed conclusion for both determinants exists: an increase in real income contributes to more efficient use of energy sources, whereas an increase in government spending on health intensifies energy usage.

Most previous relevant research has focussed on energy efficiency as measured by economic intensity and economic growth and do not relate to the issue of health expenditure. The recent health catastrophe brought on by the COVID-19 epidemic emphasises the significance of allocating more resources to health care. The findings will be helpful in the development of energy efficiency and economic policies in pursuit of sustainable development goals.

Several studies have examined the effect of formal economy (usually proxy by economic growth) on environmental quality; however, the symmetric and asymmetric impact of the informal economy on environmental quality has not been examined in Nigeria. Therefore, this study aims to explore the short- and long-run (a)symmetric effect of formal and informal economies and financial development on Nigeria’s environmental quality between 1984 and 2017.

The study uses ecological footprint to measure environmental quality. An increase in ecological footprint suggests a fall in environmental quality. Informal economy is calculated as a percentage of GDP using the currency demand approach. Autoregressive distributed lag (ARDL), nonlinear ARDL cointegration framework and vector error correction granger causality are used as estimation techniques.

The study’s outcomes establish the existence of asymmetric structure in the link between economic activities and the environment both in the short and long run. The asymmetric results reveal that positive and negative changes in the formal economy increase the ecological footprint in both periods. Hence, activities in the formal economy reduce environmental quality. On the other hand, positive and negative changes in the informal economy only positively influence the ecological footprint in the long run. In contrast, it negatively impacts the ecological footprint in the short run. This suggests that activities in the informal economy worsen the long-run environmental quality. Financial development has a positive influence on the ecological footprint, thus degrading the environmental quality. Furthermore, in the short run, a unidirectional relationship from the formal economy to the ecological footprint, while a bidirectional causality exists between informal and formal economies. Meanwhile, a unidirectional causality from the (in)formal economies and financial development to the ecological footprint was found in the long run.

The outcome of this study shows that both informal and formal economies contribute to ecological footprint; therefore, mainstreaming the informal economy into the formal economy will further increase the problem of environmental degradation and worsen environmental quality.

The study investigates the symmetric and asymmetric effect of formal and informal economies on environmental quality in Nigeria, which is largely missing in the empirical literature.

The literature argues that human activities are responsible for environmental pollution and world climate change. Africa is the second-largest continent by population and its socio-economic conditions are adversely affected by climate change due to environmental pollution. Therefore, this study investigates the relationship between human activities, the environment and the economic growth of 38 African countries from 2000 to 2018.

This study employs a simultaneous equations model called Seemingly unrelated regression.

Human capital development (HDI) and environmental health (EH) have a positive and non-linear relationship, while HDI and ecosystem vitality (EV) are negative and non-linear. The relationship between gross domestic product per capita (GDPPC) and EH is negative and non-linear. However, the GDPPC-EV link is insignificant. Trade openness (TO) and EV have a negative and non-linear relationship, but trade significantly improves EH. Urbanisation-EV relationship is positive and non-linear. However, urbanisation significantly reduces EH. Technology has a positive and non-linear relationship with EH and EV. The study also found that EH and EV positively affects the economy.

This is the first study to analyse the most concerned countries in-depth. Thus, it provides appropriate and sound policies that consider the unique characteristics of the nations. Moreover, it uses a robust estimation technique that overcomes the endogeneity problem and offers insight into the relationship between the variables, including the feedback effect of the environment on growth.

The primary purpose is to investigate the dynamic relationships among urbanization, energy use and environmental pollution in the context of India from 1971 to 2018. The paper also examines the validity of Environmental Kuznets Curve (EKC) hypothesis in the present Indian context.

The study uses a nonlinear autoregressive distributed lag cointegration test (Shin et al., 2014) to investigate the dynamic relationship among the mentioned variables. The Wald test is also used to statistically check the presence of asymmetry. Additionally, the VECM test is applied to examine the causality among the variables.

This study documents that urbanization in India is good for environment in the long run, whereas energy consumption is bad for the environment. It also finds that positive and negative shocks of energy and urbanization exert asymmetric impacts on ecological footprint. Furthermore, the results could not validate the EKC hypothesis for India.

The outcome of the study suggests designing an environmental policy which considers the nonlinearity of the investigated relationships and bearing in mind the use of comprehensive indicator like ecological footprint is equally important to address the wide-ranging problem of the environment. Policy reorientation towards the production and consumption of green energy, investment in research and development, and use of efficient technology is very crucial to achieve sustainable outcomes in the long run.

In this study, the researchers use the ‘ecological footprint’ variable to obtain a more accurate and comprehensive assessment of environmental deterioration. The mentioned dynamic relationships are investigated using an improved methodology of the NARDL model, which assumes the asymmetric impact of the explanatory variables on the response variable. The novelty of this study lies in examining the non-linear impact of urbanization and energy on ecological footprint which is inadequately addressed in the context of Indian economy.

While several existing panel studies have focused on the linear specifications of the effect of remittances and financial development on carbon emissions, nonlinear panel studies on this subject remain thin on the ground. The purpose of this paper is to examine the asymmetric effect of remittances and financial development on carbon emissions in 31 selected sub-Saharan African countries for the period spanning from 1996 to 2018.

The Kao, Pedroni and Johansen–Fisher co-integration tests were conducted to ascertain a long-run relationship among the studied variables, whereas the nonlinear panel autoregressive distributed lag approach was applied to account for asymmetries.

The study revealed, among other things, that remittances and financial development asymmetrically influence carbon emissions in the selected panel of sub-Saharan African countries. In the long run, the positive shock in remittances on carbon emissions is greater than in the negative shock in remittances. Additionally, both positive and negative shocks in financial development mitigate carbon emissions.

The implications of this study include the need to provide tax incentives to remitters and encourage them to invest in clean technologies so as to maintain sustainable development and low carbon emissions in the environment. There is also the need for governments and policymakers to formulate policies aimed at improving the functioning of the financial sectors in sub-Saharan Africa.

The positive and negative shocks of remittances and financial development on carbon emissions are examined to ascertain their asymmetric relationships.

This paper investigates the (a)symmetric effects of financial development in the presence of economic growth, energy consumption, urbanization and foreign direct investment on environmental quality of South Africa between 1980 and 2017.

A robust measure of financial development is generated using banking institutions and non-banking institutions market-based financial development indicators, while environmental quality is measured using carbon footprint, non-carbon footprint and ecological footprint. The objectives of the study are captured using linear and non-linear autoregressive distributed lag.

The result from the symmetric analysis suggests that financial development stimulates carbon footprint and ecological footprint in the short run; however, financial development abates non-carbon footprint. In the long run, financial development has a significant negative effect on carbon footprint and ecological footprint. However, the asymmetric analysis established strong asymmetric effect in the short run, while no asymmetric effect is found in the long run. The short run asymmetric analysis reveals that positive shock in financial development increases carbon footprint and ecological footprint; however, positive changes in financial development reduce non-carbon footprint. Negative shocks in financial development, on the other hand, have a positive impact carbon footprint, non-carbon footprint and ecological footprint.

The study's outcome implies that the concept of “more finance, more growth” could also be applied to “more finance, better environment” in South Africa. The study offers vital policy suggestions for the realization of sustainable development in South Africa.

This empiric adds to the body of knowledge on the influence of financial development on various components of environmental quality (carbon footprint, non-carbon footprint and ecological footprint) in South Africa.

The study aims to complement extant literature by assessing linkages between financial development, external flows and CO₂ emissions in 27 sub-Saharan African countries for the period 2002 to 2018.

The empirical evidence is based on interactive quantile regressions and external flows consist of remittances, foreign aid, trade openness and foreign investment.

The findings show minimum levels of external flows that should be reached in order for the interaction between external flows and financial development to promote environmental sustainability in terms of reducing CO₂ emissions. The minimum thresholds are critical levels of external flows that should be reached before financial development promotes environmental sustainability.

Policy implications – The disclosed external flow (i.e. FDI, foreign aid, trade and remittances) thresholds are actionable policy thresholds that the government can act upon in order to influence environmental sustainability by means of financial development. Theoretical implications – The findings below the external flow thresholds are consistent with the dependency theory in that external flows are harmful to socio-economic progress and environmental sustainability. When external flows are consolidated to the established critical masses or thresholds in the long run, the corresponding findings are in line with the extant neoclassical and endogenous growth theories, not least, because in the long run, external flows are associated with technological progress and adoption of stronger environmental legislation at the domestic level which are worthwhile in promoting environmental performance.

To reach the minimum trade and FDI levels that are worthwhile for the promotion of environmental sustainability, corporations should set targets on exports and imports as well as foreign investment levels that they have to attain in contributing to the national target of external flows needed to reduce CO₂ emissions. Such trade and FDI targets should be set in industries of various economic sectors.

The study complements the extant literature by assessing how external flows interact with financial development to influence CO₂ emissions.

The purpose of this study is to investigate what cues or surrogate indicators Muslims use to determine whether restaurants are suitable for dining purposes in the absence of the halal logo and to examine if the cues used are different among Muslims from non-Muslim countries as opposed to Muslims from Muslim countries.

Data were collected via semi-structured interviews in one Muslim majority (Malaysia) and one non-Muslim country (the UK). A total of 16 adults participated in the study with an equal representation from both countries.

In the absence of the halal logo, participants relied on extrinsic cues such as the presence of other Muslim-looking customers and service personnel to determine whether a restaurant was deemed safe for dining in. The location of a restaurant was a strong indicator for Muslims in both Muslim and non-Muslim countries. In the absence of the halal logo, participants read the menus carefully, queried the service personnel for additional information and selected safer options, such as vegetarian and seafood.

The study used a small sample, and therefore, the findings are tentative.

Given the growth of Muslim population in many non-Muslim countries, it is important for restaurants in non-Muslim countries not to marginalize this customer base. Trust is a key issue and service providers without the halal logo should gain the trust of Muslim customers by training service personnel and equipping them with knowledge of what halal means, developing menus with vegetarian and seafood options, providing detailed information on ingredients and communicating this on their websites and social media sites. They could also consider working with Muslim food and travel bloggers to promote themselves to a Muslim audience. They can develop a more Muslim sympathetic marketing approach and consider using separate cooking and serving utensils to gain trust and patronage of Muslim customers as well as to appeal to a larger market (vegans/vegetarians).

The present study is one of the first studies that concentrates on gaining an insight into how Muslims make decision pertaining to the selection and dining at a restaurant in the absence of the halal logo. A major contribution of the study is the identification of cues that assist Muslims when evaluating and selecting alternative food options in the absence of a halal logo.
