RESUMO

Environmental sustainability is vital in developing countries for sustainable economic development, poverty reduction, food security, climate change adaptation, biodiversity conservation, global equity, and access to sustainable energy. In contributing to literature, this study computed composite variables following the unavailability of a unified sustainable development goals (SDGs) database to examine the progress of ten sample developing countries. The authors propose the design of a database that utilizes the specific SDG indicators for empirical research. In testing the applicability of the proposed database, we sampled 32 indicators from the World Development Indicators database and employed principal component analysis to compute composite variables. The authors then contribute to broadening the understanding of literature by examining to what extent developing countries advance towards ensuring agricultural, energy, and environmental sustainability. And how the interplay between the SDG indicators differ across the low- and middle-income countries in terms of econometric analysis. The findings suggest that since the adoption of SDGs in 2015, developing countries have made progress in advancing water and sanitation sustainability, leading to improved environmental sustainability. Furthermore, the middle-income countries have demonstrated greater improvements in energy and agriculture sustainability compared to low-income countries in contributing to overall environmental sustainability. The developmental relationship between sustainable energy and agriculture in low- to middle-income countries reveals increased diversity, thereby presenting challenges in attaining synergy within SDGs in developing countries. Therefore, addressing and understanding the intricacies behind the adverse relationship between sustainable energy and agriculture is crucial in formulating curative policies that advance the progress of SDGs. The study concludes that environmental sustainability is a vital developmental concern to be integrated into inter-generational and intra-generational development in the SDG framework. Also, the progress of the SDG indicators is endogenous and the extent to which low-income countries lag behind middle-income towards achieving collective goals requires critical policy intervention.

RESUMO

Background: Acceptability and perception of the COVID-19 vaccine among different social groups have been the subject of several studies. However, little is known about foreign medical students in Chinese universities. Aim: This study, therefore, fills the literature gap using a focus group technique to assess the acceptance and perception of the COVID-19 vaccine among foreign medical students in China. Methods: The study adopted an online cross-sectional survey method following the Chinese universities' lockdowns to collect the data between March and April 2022. A data collection questionnaire was developed, and then the link was shared with the respondents through key informants in different universities in China to obtain the data. The data collection process only included foreign medical students who were in China from May 2021 to April 2022. The authors received a total of 403 responses from the respondents. During data processing, we excluded 17 respondents since they were not in China while administering the questionnaire to enhance the data validity. The authors then coded the remaining 386 respondents for the estimation process. We finally applied the multilinear logistics regression technique to model the COVID-19 vaccine acceptance with the response or influencing factors, including the mediating factors among the foreign medical students in China. Results: The data statistics show that 4.9% of the respondents were younger than 20 years, 91.5% were 20-40 years old, and 3.6% were older than 40 years; 36.3% of respondents were female subjects and 63.7% were male subjects. The results also show that the respondents are from six continents, including the African continent, 72.4%, Asia 17.4%, 3.1% from Europe, 2.8% from North America, 1.6% from Australia, and 2.3% from South America. The mediation analysis for the gender variable (ß = 0.235, p = 0.002) suggests that gender is a significant channel in COVID-19 vaccine acceptance and perception among foreign medical students in China. Also, the main analysis shows that opinion on the safety of the vaccine (ß = 0.081, p = 0.043), doses of the vaccine to receive (ß = 0.175, p = 0.001), vaccine safety with some side effects (ß = 0.15, p = 0.000), and the possibility of acquiring COVID-19 after vaccination (ß = 0.062, p = 0.040) are all positive factors influencing vaccine acceptability and perception. Also, the home continent (ß = -0.062, p = 0.071) is a negative factor influencing COVID-19 vaccine acceptance and perception. Furthermore, the finding shows that fear perceptions has affected 200 (51.81%) respondents. The medical students feared that the vaccines might result in future implications such as infertility, impotence, and systemic health conditions such as cardiovascular, respiratory, or deep vein thrombosis. In addition, 186 (48.19%) students feared that the vaccines were intended to shorten life expectancy. Conclusion: COVID-19 vaccination acceptability and perception among medical students in China is high, most predominantly due to their knowledge of medicine composition formulation. Despite widespread acceptance by the general public and private stakeholders, we concluded that vaccination resistance remains a significant factor among medical students and trainees. The study further adds that in considering the COVID-19 vaccine, the factor of the home continent plays a significant role in vaccine hesitancy among foreign medical students. Also, knowledge, information, and education are important pillars confronting new medicine administered among medical trainees. Finally, there is a low rate of COVID-19 vaccine hesitancy among foreign medical students in China. The study, therefore, recommends targeted policy strategies, including sensitization, detailed public information, and education, especially for medical colleges and institutions on the COVID-19 vaccination, to achieve 100%. Furthermore, the study recommends that future researchers explore other factors influencing accurate information and education for successful COVID-19 vaccination implementation.

RESUMO

This study objectively investigates the influence of energy conservation and substitution strategies in mitigating CO2 emissions in the electricity generation sector in Middle East and North Africa (MENA) region. The paper specifically explores if climate action implementation may negatively affect energy consumption on economic growth ambition and whether technical change in factor and inter-fuel substitution support in achieving sustainable development goals (SDGs) 7, 8 &13. This paper conducts the study under the life cycle analysis (LCA) procedure. We also apply stochastic frontier Translog production and ridge regression techniques with data for 2000-2015. The results currently show that renewable energy intensity falls below the breakeven level. Meanwhile, nonrenewable energy intensity is much higher. Furthermore, production factors and inter-fuel technological change show that capital-energy and renewable-nonrenewable energy are perfect substitutes under the electricity sector. Moreover, the findings reveal low energy efficiency of 40 percent with poor carbon performance. We, therefore, conclude that MENA region may not achieve cleaner, affordable energy and climate action concurrently with economic growth under the current production technologies by the fiscal year 2030. We further conclude that economic growth is presently inversely related to energy efficiency but positively with energy intensity. This suggests that MENA region economic growth drive is highly linked with nonrenewable consumption and also not supporting energy conservation strategies. Additionally, we conclude that energy efficiency improvement and reduction in energy intensity may not be achieved as the governments keep subsidizing electricity in the region. Besides, the more policymakers pursue economic growth through energy intensity indicators, the more energy is consumed through the energy rebound effects. Based on these findings and conclusions, we recommend insightful strategies under the electricity sector. This study adds new body of knowledge by extending Translog production to estimate energy intensity & efficiency under the LCA procedure. Scholars also contribute to data and variable modeling under the SDGs in discovering CO2 emission mitigation in the electricity sector which could be replicated in other countries or regions.

RESUMO

Wind energy is seen as an important energy to sustainably meet the energy needs of Ghana. However, the industry in Ghana is yet to take off due to policy uncertainty and regulatory costs. The paper analyzed the key determinants and how they interact to impact the scaling up of wind energy in Ghana, using time series data, the vector auto regression (VAR) model from 2013 to 2019.There were four endogenous variables, grouped under policy, population growth, wind capacity, and electrification rate. The findings revealed the dynamic behavior of the variables from the VAR to a strongly significant positive correlation to deploying wind energy in Ghana. The impulse response functions (IRFs) equally exhibited a positive impact long-run trajectory growth of the variables after a shock to the system. The response of the first lags had differences of log policy and that of the log of GDP produced a curious result from the shock by taking a steady positive growth path in the short run and nosedived to a negative pathway in the long run. On the other hand, the interaction of the first differences of the lags of log wind capacity and log policy is quite instructive, as the headwind produced a negative relationship in the short run and to a positive growth path in the long run. This was anticipated, as the wind capacity installation of Ghana is expected to increase in the long run, when pipeline projects materialize.
