The current study examined the impact of population ageing on environmental quality in 17 late-demographic dividend (LDD) countries.

The panel autoregressive distributed lag (ARDL) model using pooled mean group (PMG) estimator based on the environmental Kuznets curve (EKC) hypothesis was used to analyse data for the period 1990–2018.

The empirical results demonstrated that in the long run, carbon dioxide (CO₂) emissions decrease with population ageing. The prevailing findings also indicated no sufficient evidence of EKC hypothesis validity and electricity consumption, which is the primary driving force of CO₂ emissions in LDD countries.

Unlike prior works, this paper is among the first to discuss environmental quality due to the current demographic transition towards ageing among LDD countries. Based on the results, population ageing reduces the environmental deterioration. The identification of possible ageing impact is vital to combat the climate change in order for countries to achieve sustainability, better economy and quality environment.

The surface finish is an essential step in printed circuit boards design because it provides a solderable surface for electronic components. The purpose of this study to investigate the effects of different surface finishes during the soldering and ageing process.

The solder joints of Sn-4.0Ag-0.5Cu/Cu and Sn-4.0Ag-0.5Cu/electroless nickel/immersion silver (ENImAg) were investigated in terms of intermetallic (IMC) thickness, morphology and shear strength. The microstructure and compositions of solder joints are observed, and analyzed by using scanning electron microscopy (SEM-EDX) and optical microscope (OM).

Compounds of Cu₆Sn₅ and (Cu, Ni)₆Sn₅ IMC were formed in SAC405/Cu and SAC405/ENImAg, respectively, as-reflowed. When the sample was exposed to ageing, new layers of Cu₃Sn and (Ni, Cu)₃Sn₅ were observed at the interface. Analogous growth in the thickness of the IMC layer and increased grains size commensurate with ageing time. The results equally revealed an increase in shear strength of SAC405/ENImAg because of the thin layer of IMC and surface finish used compared to SAC405/Cu. Hence, a ductile fracture was observed at the bulk solder. Overall, the ENImAg surface finish showed excellent performance of solder joints than that of bare Cu.

The novel surface finish (ENImAg) has been developed and optimized. This alternative lead-free surface finish solved the challenges in electroless nickel/immersion gold and reduced cost without affecting the performance.

This research aims to identify malnutrition risk and perception of malnourished and at-risk elderly individuals on their dietary practices.

In Phase 1, a cross-sectional study was conducted among 413 elderly individuals aged 60 years and above in agricultural settlements in Kuantan, Pahang, Malaysia. Malnutrition risk was assessed using the Mini Nutritional Assessment Short-Form (MNA-SF). In Phase 2, in-depth semi-structured interviews were conducted among 21 elderly individuals identified in Phase 1. The interviews ceased when data saturation was achieved.

25.7 per cent (n = 106) of elderly individuals were identified as malnourished and at-risk (MNA-SF score = <12). Age, smoking, income and living status were significantly associated with malnutrition risk (p < 0.05). Thematic analysis revealed four themes that represent elderly individuals’ perception on their dietary practices: the impact of aging on dietary intake; food restriction according to health condition; poor dietary intake due to feeling of loneliness; and perceived benefits of foods for health.

Strategies from multidisciplinary healthcare professionals to eliminate improper dietary practice are required for the maintenance of health, functional independence and quality of life among the elderly.

This research is at the forefront in reporting the elderly individuals’ perception on dietary practice in agricultural settlement. Attention to individual’s health issues and the associated factors that may influence their dietary practices is essential to provide appropriate interventions to achieve optimum nutritional status and healthy aging.

This study aims to investigate dietary intake among elderly living in agricultural settlements in comparison with a recent nutritional recommendation.

This cross-sectional study was carried out among elderly living in five agricultural settlements in Kuantan, Pahang, Malaysia. Participants were interviewed on socio-demographic information such as age, gender, marital status, smoking status, household income, education level and living status. Data on individual dietary intake were obtained through diet history method. Dietary intake data were analyzed using Nutritionist Pro software and compared to the recommended nutrient intakes (RNI) for Malaysia version 2017. Statistical analyses were performed using SPSS software version 21.

A total of 413 participants (male 32.4 per cent and female 67.6 per cent) with the mean age of 69.4 ± 7.9 years participated in this study. Dietary intake results demonstrated that participants did not meet the Malaysian RNI for energy and most nutrients (p < 0.05). This study also found that energy, carbohydrate, protein, fat, folate and iron intake were significantly higher in male than female (p < 0.05). Meanwhile, calcium and vitamin A intake were significantly higher in female than male (p < 0.05).

Integrated nutrition education and health promotion programme with a multidisciplinary approach are essential to be designed and executed to improve dietary intake of the elderly, which can further lead to appropriate dietary practices and knowledge improvement related to healthy food choices. Factors associated with inadequate dietary intake and awareness on the importance of adequate nutrients intake among the elderly warrant further investigation.

This research is at the forefront, which indicated that the dietary intake of elderly individuals living in the agricultural settlement was inadequate in comparison to the latest recommendation. Strategies to improve their intakes need to be developed and implemented accordingly to improve nutritional status and prevent adverse effects to health.

The purpose of this research is to examining the effect of transformational leadership on work stress, organizational citizenship behavior (OCB) and turnover intention, examining the effect of work stress on OCB and turnover intention and examining the effect of OCB on turnover intention.

Data were collected using the survey method, with questionnaires and data analysis were done employing the WarpPLS with two approaches. This research finds the results of this study indicate that the higher the transformational leadership, the lower the work stress will be. The positive significant relationship might be because of direction or command given by the leaders to nurses at each meeting held regularly.

The results of this study indicate that the higher transformational leadership, the lower the turnover intention will be even though it is not significant. The results of this study indicate that the higher the work stress, the lower the OCB, although not significant.

Previous studies have not examined the relationship of the variables mentioned above, especially in Manado where the respondents have different cultures.

The purpose of this paper is to identify the driving forces that influence family Takaful demand in Malaysia. The paper examines various identified and available economics and socio‐demographic variables.

Using ordinary least square (OLS) and generalised method of moments (GMM) techniques, the paper investigates the significance of the identified economic and socio‐demographic factors in determining the consumption of family Takaful. The paper first examines a full model that combines all variables; second, a model that controls for product market factors; and finally, a model that controls for socio‐demographic factors. Following Anderson and Nevin, Haberman, Lenten and Rulli and Josa the paper further separates all models into linear and log‐linear demand functions.

The paper demonstrates that income, Islamic banking development, education, dependency ratio and Muslim population factors are positively related to Takaful demand. On the other hand, inflation, real interest rate, financial development and life expectancy appear to be the significant factors that adversely influence the total family Takaful consumption.

The major limitation of this paper is the small sample size. Therefore, future studies may expand the variables omitted in this study due to unavailability of data, which may be influential in explaining the family Takaful demand in Malaysia. Possible influential variables may include government social security expenditure, price of Takaful and level of competition within the Takaful and insurance industry. Research should also be conducted on the impact of the legal system and government policies on the demand for family Takaful in the country. Finally, the study focuses solely on the determinants of demand for family Takaful. Nevertheless, the supply‐side of the equation should not be neglected and should be incorporated in future studies.

It is obvious that there are very few studies that focus on the Malaysian market and indeed, none of them gives attention to the factors that influence demand for family Takaful. In this regard, this study contributes in filling the gaps in the scope and coverage of studies in similar area. While this study is expected to provide more understanding and awareness on the concept of Takaful and the factors that influence its demand, the authors hope that it would encourage more studies on various issues on the Takaful industry so as to help researchers to understand more aspects of this new emerging business.

The purpose of this study is to dissect the transport infrastructure performance, public spending in transport infrastructure development and the manufacturing sector in determining the transport sector energy consumption.

An analysis of transport energy consumption with the transport infrastructure performance, public spending in transport infrastructure and manufacturing sector output in India using annual data for the period 1987–2019. The study used the autoregressive distributed lag (ARDL) bounds test approach along with FMOLS, DOLS and canonical cointegration regression (CCR) methods.

The results of the ARDL bounds test provide evidence for the long- and short-run relationships among study variables. It evidenced that transport infrastructure performance reduces transport energy consumption by using FMOLS, DOLS and CCR methods. Furthermore, the inference of the positive impact of value added in the manufacturing sector on transport energy consumption validates the higher energy demand of the manufacturing sector from a mobility perspective.

The estimated finding of this study is expected to be contributing to policy-making discussions on transport infrastructure and manufacturing sector development in an emerging economy like India with insights on energy consumption.

To the best of the authors’ knowledge, this is the first study that integrates the impact of manufacturing sector output on transport sector energy consumption along with transport infrastructure performance and public investment in the transport infrastructure.

The purpose of this paper is to investigate the effects of Sn-Ag-x leveling layers on the mechanical properties of SnBi solder joints. Four Sn-Ag-x (Sn-3.0Ag-0.5Cu, Sn-0.3Ag-0.7Cu, Sn-0.3Ag-0.7Cu-0.5 Bi-0.05Ni and Sn-3.0Ag-3.0 Bi-3.0In) leveling layers were coated on Cu pads to prepare SnBi/Sn-Ag-x/Cu solder joints. The microstructure, hardness, shear strength and fracture morphology of solder joints before and after aging were studied.

The interfacial brittleness of the SnBi low-temperature solder joint is a key problem affecting its reliability. The purpose of this study is to improve the mechanical properties of the SnBi solder joint.

Owing to the addition of the leveling layers, the grain size of the ß-Sn phase in the SnBi/Sn-Ag-x/Cu solder joint is significantly larger than that in the SnBi/Cu eutectic solder joint. Meanwhile, the hardness of the solder bulk in the SnBi/Cu solder joint shows a decrease trend because of the addition of the leveling layers. The SnBi/Cu solder joint shows obvious strength drop and interfacial brittle fracture after aging. Through the addition of the Sn-Ag-x layers, the brittle failure caused by aging is effectively suppressed. In addition, the Sn-Ag-x leveling layers improve the shear strength of the SnBi/Cu solder joint after aging. Among them, the SnBi/SACBN/Cu solder joint shows the highest shear strength.

This work suppresses the interfacial brittleness of the SnBi/Cu solder joint after isothermal aging by adding Sn-Ag-x leveling layers on the Cu pads. It provides a way to improve the mechanical performances of the SnBi solder joint.

The present study aims to investigate the dynamic relationship between international tourist receipts, economic growth, energy use and carbon dioxide (CO₂) emissions in Pakistan over the period 1980-2016. Many researchers have investigated the link between tourism and CO₂ emissions, but there is no clear picture as the results are contradictory. This study is an attempt to compliment the literature related to tourism and environmental quality.

The study adopted the autoregressive distributed lagged (ARDL) model to investigate the short- and long-run estimates simultaneously. The study further applied Granger causality to find out the direction of causalities. To arrive at long-run robust estimates, the study used dynamic ordinary least squares (DOLS) model.

The results found that tourist receipts have no significant impact on environmental quality, while growth and energy consumption are the main determinants of CO₂ emissions in Pakistan. The Granger causality test confirmed unidirectional causalities from GDP and energy consumption toward CO₂ emissions, while tourist receipts do not affect environmental quality. DOLS technique confirmed the long-run estimates of ARDL model.

The result of the study complements the literature by adding new evidence regarding the nexus of tourism and environment. Findings of the study are important for policymakers and regulatory bodies to place their focus on the development of tourism sector (services sector) rather than energy-intensive manufacturing activities to sustain the growth of the country in higher quartiles, as tourism receipts have no significant negative externalities toward environment, while energy use is one of the key determinants of environmental degradation.

This study used time series data over the period 1980-2016 for Pakistan to inspect the dynamic relationship between tourist receipts, economic growth, energy consumption and CO₂ emissions.

There is a paucity of empirical studies on the impact of entrepreneurial management on small and medium enterprises (SME) performance. Against this backdrop and drawing upon the resource-based view, this study aims to explore the relationship between entrepreneurial management and SME performance and the mediating role of competitive advantage in an emerging economy.

This study adopted a survey research design and a quantitative approach. A self-reported questionnaire was used to collect data from a conveniently selected sample of 174 manufacturing SMEs in Nigeria. This study performed mediation analysis to test the proposed hypotheses using Hayes’ PROCESS macro v4.

The findings indicate that entrepreneurial management positively impacts competitive advantage and SME performance. Furthermore, competitive advantage has a positive impact on SME performance and plays a significant mediating role in the relationship between entrepreneurial management and SME performance.

This study only examines manufacturing SMEs in a single country, Nigeria; thus, the generalisability of its findings is limited.

The findings of this study offer practical implications for SMEs and SME owners or managers. The findings suggest that to gain a sustainable competitive advantage and achieve superior performance, SMEs should pursue opportunities regardless of the available resources, promote flat and flexible organisation structures, adopt fast growth orientation and strategies, reward employees based on the value they add to the organisation and foster an entrepreneurial culture.

To the best of the authors’ knowledge, this study is the first to provide empirical evidence of the mediating effect of competitive advantage on the relationship between entrepreneurial management and SME performance in an emerging economy. This study demonstrates that implementing entrepreneurial management practices by SMEs can result in sustainable competitive advantage and superior performance.
