The purpose of this study is to examine households’ behavior towards dirty cooking energy utilisation in an environment where relatively higher accessibility to clean energy is noted. Although the low utilisation rate of clean energy can partly be attributed to utility gains anticipated in dirty energy mixes (DEMs) arising out of accessibility constraints, affordances and enablers, it is still unclear on the extend at which each of these contributes towards DEMs manifestation among the seemingly well-to-do households with higher levels of clean energy mixes (CEM) access. This study, therefore, hinges on scrutinising on this lower utilisation patterns despite a seemingly higher accessibility of CEMs, specifically liquified petroleum gases (LPG).

The study is based on a household’s survey that was carried out in 2018, reaching a sample of 393 households using questionnaires in four wards of the Kigamboni district in Tanzania. Subsequent analyses were descriptive as well as inferential based on binary logistic regression analysis where utilisation of DEMs was predicted for both the high and low social economic status (SES) households by incorporating accessibility constraints, affordances and enablers.

The results show, first, if one assumes energy stacking is not an issue, as households become more constrained towards CEMs utilisation, they shift towards DEMs suggesting that the overall effect is a substitution, and second, the complementarity effect ultimately outweighs the substitution effect as households do not shift from DEMs to CEMs rather stack multiple energy. DEMs flourish in this case study area because those with high income are among those in the lowest SES, and some of those with the highest SES are from among the lowest income category, and all of them end up with more DEMs because shifting towards CEMs require income to complement SES.

Policy-wise, removing hurdles in accessing CEMs such as LPG subsidy programme, gas stove provision to the poor, and enhanced LPG awareness will most likely benefits only those who do not stack energy in cooking while strategies targeting those at the lowest SES such as higher education attainment, empower women as a family decision maker, encourage co-occupancy to enlarge the household size and contain urban growth within certain perimeter will have a significant impact only if they raise both incomes and SES.

Despite of the dominance of DEMs for cooking such as charcoal and firewood in Tanzania, CEMs such as LPG, have emerged as complements or alternatives in the household energy basket. The utilisation of such CEMs is, however, still very low despite the accessibility, cost, environmental and health advantages they offer. Accessibility is not the only factor fuelling CEMs; a complementarity must exist between SES and income for the positive transition towards CEMs to be realised.

This study aims to improve the reliability of emergency safety barriers by using the subjective safety analysis based on evidential reasoning theory in order to develop on a framework for optimizing the reliability of emergency safety barriers.

The emergency event tree analysis is combined with an interval type-2 fuzzy-set and analytic hierarchy process (AHP) method. In order to the quantitative data is not available, this study based on interval type2 fuzzy set theory, trapezoidal fuzzy numbers describe the expert's imprecise uncertainty about the fuzzy failure probability of emergency safety barriers related to the liquefied petroleum gas storage prevent. Fuzzy fault tree analysis and fuzzy ordered weighted average aggregation are used to address uncertainties in emergency safety barrier reliability assessment. In addition, a critical analysis and some corrective actions are suggested to identify weak points in emergency safety barriers. Therefore, a framework decisions are proposed to optimize and improve safety barrier reliability. Decision-making in this framework uses evidential reasoning theory to identify corrective actions that can optimize reliability based on subjective safety analysis.

A real case study of a liquefied petroleum gas storage in Algeria is presented to demonstrate the effectiveness of the proposed methodology. The results show that the proposed methodology provides the possibility to evaluate the values of the fuzzy failure probability of emergency safety barriers. In addition, the fuzzy failure probabilities using the fuzzy type-2 AHP method are the most reliable and accurate. As a result, the improved fault tree analysis can estimate uncertain expert opinion weights, identify and evaluate failure probability values for critical basic event. Therefore, suggestions for corrective measures to reduce the failure probability of the fire-fighting system are provided. The obtained results show that of the ten proposed corrective actions, the corrective action “use of periodic maintenance tests” prioritizes reliability, optimization and improvement of safety procedures.

This study helps to determine the safest and most reliable corrective measures to improve the reliability of safety barriers. In addition, it also helps to protect people inside and outside the company from all kinds of major industrial accidents. Among the limitations of this study is that the cost of corrective actions is not taken into account.

Our contribution is to propose an integrated approach that uses interval type-2 fuzzy sets and AHP method and emergency event tree analysis to handle uncertainty in the failure probability assessment of emergency safety barriers. In addition, the integration of fault tree analysis and fuzzy ordered averaging aggregation helps to improve the reliability of the fire-fighting system and optimize the corrective actions that can improve the safety practices in liquefied petroleum gas storage tanks.

This study aims to determine the effects of lodging infrastructure development (LID) on Cordillera Administrative Region’s (CAR) environmental quality and natural resource management and its implication to globally responsible leadership. Specifically, this study sought to determine the contribution of LID to environmental deterioration and natural resource degradation in the CAR. As a result, a mathematical model is developed, which supports sustainability practices to maintain the environmental quality and natural resource management in CAR, Philippines.

This study used a descriptive research design using a mixed-methods approach. Self-structured interview and survey were used to gather the data. The population of this study involved three groups. There were 6.28% (34) experts in the field for the qualitative data, 70.24% (380) respondents for the quantitative data and 23.47% (127) from the lodging establishments. 120 respondents from the Department of Tourism – CAR (DOT-CAR) accredited hotels. Nonparametric and nonlinear regression analysis was used to process the data.

The effects of LID on the environmental quality and natural resource management in CAR as measured through carbon emission from liquefied petroleum gas (LPG), electricity and water consumption in the occupied guest rooms revealed a direct correlation between the LID. Findings conclude that the increase in tourist arrival is a trigger factor in the increase in LID in the CAR. The increase in LID implies a rise in carbon emission in the lodging infrastructure. Any increase in tourist arrivals increases lodging room occupancy; the increased lodging room occupancy contributes to carbon emissions. Thus, tourism trends contribute to the deterioration of the environmental quality and degradation of the natural resources in the CAR. A log-log model shows the percentage change in the average growth of tourist arrival and the percentage increase in carbon emissions. Establishments should observe standard room capacity to maintain the carbon emission of occupied lodging rooms at a minimum. Responsible leadership is a factor in the implementation of policy on standard room capacity.

The result of the study has some implications for the lodging businesses, the local government unit (LGU), the Department of Tourism (DOT) and the Department of Environment and Natural Resources (DENR) in the CAR. The study highlights the contribution of the lodging establishments to CO₂ emission, which can degrade the quality of the environment, and the implication of responsible leadership in managing natural resources in the CAR. The direct inverse relationship between energy use and CO₂ emission in hotels indicates that increased energy consumption leads to environmental degradation (Ahmad et al., 2018). Therefore, responsible leadership among policymakers in the lodging and government sectors – LGU, DOT and DENR – should abound in the CAR. Benchmarking on the model embarked from this study can help in designing and/or enhancing the policy on room capacity standardization, considering the total area with its maximum capacity to keep the carbon emission at a lower rate. Furthermore, as a responsible leader in the community, one should create programs that regulate the number of tourists visiting the place to decrease the number of overnight stays. Besides, having the political will to implement reduced room occupancy throughout the lodging establishments in CAR can help reduce the carbon emissions from the lodging businesses. After all, one of the aims of the International Environment Protection Organization is to reduce CO₂ emissions in the tourism industry. Hence, responsible leadership in environmental quality preservation and sustainable natural resource management must help prevent and avoid greenhouse gas (GHG) emissions.

Most studies about carbon emission in the environment tackle about carbon dioxide emitted by transportation and factories. This study adds to the insights on the existing information about the carbon emission in the environment from the lodging establishments through the use of LPG, electricity and water consumption in the occupied guest rooms. The findings of the study open an avenue for globally responsible leadership in sustaining environmental quality and preservation of natural resources by revisiting and amending the policies on the number of room occupancy, guidelines and standardization, considering the total lodging area with its maximum capacity to keep the carbon emission at a minimum, thus contributing to the lowering of GHG emissions from the lodging industry.

This research paper aims to examine the asymmetric impact of income and price on household consumption of kerosene in Cameroon.

The methodological approach consists of testing for stationarity using the augmented Dickey–Fuller and Andrews and Zivot tests, determining cointegration using nonlinear autoregressive distributed lag (NARDL) test approach and finally examining asymmetry using the Wald test.

Results of the stationarity tests reveal that variables are all integrated of order less than two I(2). The NARDL approach indicates that the (positive and negative) income shock and the positive price boom negatively influence consumption in the long- and short-run. The same is true for the negative price shock, but the latter remains insignificant. Furthermore, the Wald test carried out in the study confirms that the cumulative effects of the positive and negative income and price shocks are asymmetric.

The increase in the price of kerosene due to the lifting of subsidies has led to a decrease in household consumption and an unfortunate increase in the loss of tree cover in Cameroon. According to the results, this phenomenon will persist even if the price is reduced. Actions aimed at reducing its production at the expense of liquefied petroleum gas, electricity and renewable energy should be encouraged to limit the loss of vegetation cover. Thus, this study could contribute to solving the problem of deforestation and desertification in Cameroon.

The hospitality industry is one of Ghana's key economic contributors. It is an industry that has significant indigenous investment. The sector also brings in foreign exchange for Ghana. In 2019, it generated $325 m through tourist visits. This makes the hospitality industry critical for the attraction of foreign direct investments. The research was therefore aimed at examining the business environment of the hospitality industry for evidence of negative factors that can hamper its greater contribution to the attainment of Goal 8 of the 17 Sustainable Development Goals of the UN such as guest-bullying and the incivility in hospitality occupations.

A convenience sampling method was used to select 346 samples out of the accessible 3,500 targeted population from 38 hotels in the capital city of Ghana, Accra, comprising of junior to senior employees of various departments. The questionnaires were scripted from a paper-based to digital format supported by the Opine software installed on tablets and smartphones, to enable complete adherence to all coronavirus disease 2019 (COVID-19) safety protocols. The study used a regression to ascertain the relationships between the dependent variables and the independent variables.

The study found the “Level of Permissiveness for Guests” positively and significantly “encouraged” guests to bully staff, while “Management and Staff Laxity” negatively but significantly explained guest bullying behaviour.

The study makes the first attempt in context to shed light on workplace bullying which represents one of the main factors that can inhibit or erode any gains or attempts to foster the achievement of Goal 8 of the 17 Sustainable Development Goals of the UN which is to create “Decent Work and Economic Growth”.

In 1991, India embarked on market-based economic reforms initiatives pillared on liberalization, privatization and globalization (LPG). The reforms exposed the public sector enterprises to competitive market forces, raising the need to identify and develop the competencies necessary for survival. Executive training programs were initiated to prepare public enterprises for the market-based reforms. Three decades later, the reforms especially privatization is witnessing renewed interest under the current administration. In this context, the article takes a closer look at the structure of management education provided to public sector officers in India. The article also identifies barriers for implementing the learnings from the management courses in the workplaces and suggests approaches for closing the gap.

The study follows a thematic approach based on unstructured interviews of senior executives of Indian public sector enterprises covering oil and gas, aeronautical, power and transportation sectors. New public management (NPM) is used as a yardstick of “business-like” characteristics of public sector enterprises.

Despite heavy investment, trainings have had only partial success in implementing the core objective of NPM, i.e. to provide quality services in a professional manner to meet citizen requirements. The study found that though concepts of NPM are introduced at multiple management training programs, the public enterprises lag in the implementation of NPM. The ingrained hierarchical and procedural culture of the enterprises was often highlighted as the challenge to its implementation.

The study will be of significance to Indian policymakers in designing management education programs to public sector employees. It brings out – (1) various models of management education provided to public servants across industries, (2) provide evidence on the extent of NPM implementation, (3) identify barriers for transitioning the learnings from the management courses to workplace and (4) suggest changes for improving effectiveness.

The existing research on LPG in India covers the economic transformation post-implementation and the factors contributing to the success of its implementation. This study adds to the limited literature available on the management education of public servants in the country.

This paper aims to understand what green tax measures Portuguese corporate tax law foresees and whether the measures observe the polluter pays tax principle.

The legal research method is applied to achieve the goals. Specifically, the research analyzes the most relevant corporate tax legislation to identify legal provisions influencing taxpayers’ behavior in sustainability decisions, particularly corporate income tax (CIT) and value-added tax (VAT) laws.

The results show that the Portuguese Green Taxation Law introduces several environmentally friendly taxation measures by benefiting or increasing the tax burden. The influence on the CIT law results from instruments such as the autonomous taxation of expenses, depreciation, provisions and the local corporate tax. In the VAT, electric tourism vehicles’ VAT deduction is possible. These measures enforce the polluter pays tax principle, increasing the tax burden on less environmentally friendly options and decreasing the tax burden on more green economic choices. These measures directly influence the companies’ choice because of the increase or decrease tax burden according to more or less polluting choices.

This study only studies the Portugal case.

This study highlights the Portuguese experience reconciling taxation and environmental dimensions.

This study aims to establish whether three technology-specific attributes – convenience, compatibility with cultural needs and social reputation – influence the sustained use of clean cooking technologies in Uganda’s households.

This study adopted a cross-sectional and correlational research design. A survey was conducted with 125 households. The data were analyzed using SPSS and Smart PLS.

The results indicate that, in contrast to convenience, social reputation and compatibility with cultural needs significantly influence the sustained use of clean cooking technologies in Uganda’s households.

This study focused on the Greater Kampala Metropolitan Area; hence, several households in other urban centers and rural communities were excluded from the study. In addition, technology-specific attributes only accounted for 34.4% of the variation in the sustained use of clean cooking technologies in Uganda, leaving 65.6 unexplained. Therefore, the authors recommend that future studies look at other technology-specific attributes that may influence the sustained use of clean cooking technologies in Uganda’s households.

This study provides initial evidence of technology-specific attributes and the sustained use of clean cooking technologies based on the expectation–confirmation model.

This article aims to optimise energy use and consumption by integrating Lean Six Sigma methodology with the ISO 50001 energy management system standard in an Irish dairy plant operation.

This work utilised Lean Six Sigma methodology to identify methods to measure and optimise energy consumption. The authors use a single descriptive case study in an Irish dairy as the methodology to explain how DMAIC was applied to reduce energy consumption.

The replacement of heavy oil with liquid natural gas in combination with the new design of steam boilers led to a CO₂ footprint reduction of almost 50%.

A further longitudinal study would be useful to measure and monitor the energy management system progress and carry out more case studies on LSS integration with energy management systems across the dairy industry.

The novelty of this study is the application of LSS in the dairy sector as an enabler of a greater energy-efficient facility, as well as the testing of the DMAIC approach to meet a key objective for ISO 50001 accreditation.

This paper shows how the interplay between organisational resilience and environmental complexity justifies the existence of differentiated yet successful approaches to digital transformation.

A multi-case method is applied to test our research hypotheses by contrasting the digital transformation of three Italian companies in the valves industry.

Different combinations of technological and organisational tools, hence diversified digital transformations, can be successful, provided that they are supported by a coherent set of resilience factors and allow for the implementation of strategic approaches aligned with the resilience capacity of the firm.

Awareness that resilience capacity shapes digital transformation and the strategies available to engage with external complexity should focus managers to invest in the alignment and the reinforcement of the factors underlying organisational resilience.

Most literature so far focused on the antecedents to digital transformation. In contrast, this paper focuses on the transformation process and highlights how the resilience capacity of the firm affects the unfolding of digital transformation and the emergence of diversified yet successful paths. In addition, in contrast with a dichotomous approach to external complexity this paper shows that digital transformation involves a mix of complexity reduction and complexity absorption strategies.
