Abstract
Purpose
Work engagement denotes to a state of positive and affective motivation of elevated power joined with high educational levels and a great concentration on occupation and it is negatively affected by psychological problems. This study aims to assess the stress and work engagement among Palestinian nurses working in intensive care units.
Design/methodology/approach
A cross-sectional design was adopted. A convenience sample consisting of 225 intensive care nurses from governmental hospitals was recruited to participate. Data collection used the Nursing Stress Scale and Utrecht Work Engagement Scale-9, and demographic data were used to gather data throughout the period from February 10 to March 30, 2023.
Findings
Findings demonstrated that nurses’ stress levels were high (M = 105.9 ± standard deviation [SD] = 11.91). Concerning work engagement, the nurses endorsed moderate work engagement levels with a mean of 3.7 (SD = 0.4). Regarding work engagement subscales, the mean of vigor was 3.7 (0.6), dedication with a mean of 3.7 (0.6) and absorption with a mean of 3.7 (0.6). Also, the findings showed that stress, gender and monthly income were predictors of work engagement (p < 0.05).
Research limitations/implications
Despite the significant results, this study had the following limitations: the design was cross-sectional, which limits the ability to explore the cause and effect of the study variables, thus longitudinal studies are recommended. In addition, the study adopted a self-reported questionnaire based on participants’ understanding, culture and work context which could influence their responses.
Originality/value
The intensive care nurses had high stress levels and moderate work engagement. Stress, gender and monthly income were predictors of the work engagement. Thus, interventions should be encouraged to minimize stress, which has a significant influence on work engagement.

Abstract
Purpose
This paper aims to compare the impacts of adaptive daily and seasonal cooling setpoints on cooling energy consumption and overheating hours to determine which approach is more effective in a desert climate, develop a methodology that effectively integrates passive strategies with adaptive daily and seasonal cooling setpoint strategies and assess how future climate conditions will impact these strategies in the medium and long term.
Design/methodology/approach
(1) Integrate adaptive thermal comfort principles into mechanical cooling systems to find the optimized cooling setpoint. (2) Evaluating the optimized cooling setpoints using a mixed-mode operation: In this step, the natural ventilation is activated by opening 40% of the window area when the indoor temperature is higher than 23°C and the outdoor temperature. Both the adaptive seasonal and daily setpoint strategies are evaluated. (3) If overheating hours exceed acceptable limits gradually add mitigation measures (e.g. exterior shading, cool roofs and green roofs). (4) If necessary, further reduce the cooling setpoint until acceptable limits are met. (5) Generate extreme future climate scenarios and evaluate the optimized model. (6) Implement additional measures and setpoint adjustments to maintain acceptable overheating hours in future conditions.
Findings
Although the building complies with the Dubai Green Code and uses external shading, its cooling energy consumption was 92 kWh/m² in 2021 with a 24°C setpoint. Using the adaptive seasonal setpoint combined with a cool roof, night cooling and cross-ventilation reduces cooling energy consumption by 52, 48 and 35% in 2020, 2050 and 2090, respectively, with overheating hours not exceeding 40 h annually. Using an adaptive daily setpoint strategy with the same mitigation measures is similarly effective; it achieved a 57, 42 and 34% reduction in cooling energy consumption in 2020, 2050 and 2090, respectively, while eliminating overheating hours.
Originality/value
The originality and value of this study lie in optimizing cooling setpoints without the effect of overheating hours in desert climates. Using the adaptive seasonal setpoint combined with a cool roof, night cooling and cross-ventilation reduces cooling energy consumption by 52, 48 and 35% in 2020, 2050 and 2090, respectively, with overheating hours not exceeding 40 h annually. Using an adaptive daily setpoint strategy with the same mitigation measures is similarly effective; it achieved a 57, 42 and 34% reduction in cooling energy consumption in 2020, 2050 and 2090, respectively, while eliminating overheating hours.

Abstract
Nowadays, the main challenge in the higher education is the daunting task of transforming universities into digital era institutions. Improving HE students' competence to meet the flow of technological innovations through DT has been the focus of many countries. This task has imposed the restraint that HE institutions should implement the most effective strategies of DT. This chapter is focusing on how DT strategies play their role in making the transformation itself become germane and give its fruits. Therefore, this chapter presents the most effective DT strategies that can be implemented by HE institutions in order to prepare their students for the existing professional roles in their societies. A good DT strategy is one that connects the organization's current level of digital maturity with its future ambition. The well-known strategies in the DT field are as follows: the strategy of electronic projects, strategy of smart electronic platforms, integrated training strategy, participatory e-learning strategy, smart learning strategy, pervasive learning strategy, microlearning strategy and e-design thinking strategy, in addition to the strategy in which traditional learning methods are combined with e-learning methods. It is worth noting here that the chapter is not an attempt to favor a strategy over another or compare and contrast them to uncover their differences at any level. On the contrary, the writer will work on displaying how each strategy can be implemented in order to accomplish DT in HE instructional practices. Also, this chapter will show how complementary these strategies can be once they are utilized to reach DT.

Abstract
Small islands are particularly vulnerable to environmental impacts, as multiple environmental as well as socio-economic changes are impacting their local communities and especially the most vulnerable segments of their population. Information and communication technologies (ICTs) are increasingly viewed as an opportunity for small islands to mitigate and adapt to climate change. ICT may help to monitor short-term and long-term climate trends, raise awareness, help protect the environment and reduce carbon emissions. Though the ICT sector has been recognised as crucial in ensuring sustainable development, it is also important to address its potential adverse impacts like energy consumption, electronic waste generation and digital inequality among others. The ICT-environment link is thus rather complex. While there is extensive literature on the ICT-climate change nexus, the evidence remains mixed. The evidence on small island economies is rather scant. The objective of this chapter is to investigate into the ICT and environment linkage for small islands taking on board the specificities of island economies. The Panel Vector Error Correction Model (PVECM) is used on 38 small islands over a period 2000–2020, and the long-run results show that higher use of ICT has resulted in lower carbon emissions.

Abstract
Turbulent times include economic crises, recessions, health pandemics, war situations, including the recent COVID-19 crisis which had significant economic and social ramifications. Turbulence impacts the economy, businesses, and societies as whole. Crises impact the education industry not only in terms of teaching and learning but also the next level of learning outcome as job opportunities and career growth of the stakeholders. University systems play a major role in handling turbulence and generating resilience methods to ensure the least possible impact on the sector. The entrepreneurial mindset of the universities encourages them towards risk-taking, becoming initial movers, and being innovators in their approaches (Etzkowitz et al., 1998). This chapter provides a broader understanding of different types of turbulence, as well as the intensity of impact on the higher education sector. It also discusses how these turbulent times come with opportunities which can be leveraged by institutions. With an extensive literature review and understanding, it proposes a conceptual multilayered model to support entrepreneurial development. This study employs desk research methods to understand, review, and propose methods and methodology to encourage and adapt universities handling turbulence and crises. Lack of research in handling crises and turbulence in the case of higher education makes this study imperative. The outcome extends the conceptual understanding of turbulent situations and will help the universities to self-introspect and understand the ways for reacting to these changes, crises, and turbulences. Discussion on National Education Policy enhances the understanding for educators and universities to utilize added opportunities.

Abstract
This study examines the social acceptance and potential for residential solar integration in Abu Dhabi to support sustainable urban innovation and prosperity. A survey of 216 Abu Dhabi residents analyzed four scenarios for incentivizing household solar panel adoption. Results demonstrate high interest and preference for governmental financial support mechanisms to spur solar integration. This research contributes an assessment framework and citizen engagement insights that could inform smart city development strategies focused on renewable energy transformation across the Gulf region. As urban centers like Abu Dhabi strive to enact their visions for economic diversification and environmental sustainability, understanding citizen perspectives on innovations like distributed solar will be critical to align technology advancement with societal needs and values. The methodology and findings of this Abu Dhabi case study provide a model to catalyze stakeholder buy-in for new energy solutions, with potential applications for other Gulf cities aiming to transition their energy systems and build integrative renewables infrastructure to power next-generation smart development. This solar integration acceptance research lays the groundwork for continued scholarly discourse and policymaker collaboration around smart cities in the Gulf that realize multidimensional progress for society, economy, and environment.

Abstract
Purpose
In the online environment, consumers increasingly feel vulnerable due to firms’ expanding capabilities of collecting and using their data in an unsanctioned manner. Drawing from gossip theory, this research focuses on two key suppressors of consumer vulnerability: transparency and control. Previous studies conceptualize transparency and control from rationalistic approaches that overlook individual experiences and present a unidimensional conceptualization. This research aims to understand how individuals interpret transparency and control concerning privacy vulnerability in the online environment. Additionally, it explores strategic approaches to communicating the value of transparency and control.
Design/methodology/approach
An interpretivism paradigm and phenomenology were adopted in the research design. Data were collected through semi-structured interviews with 41 participants, including consumers and experts, and analyzed through thematic analysis.
Findings
The findings identify key conceptual dimensions of transparency and control by adapting justice theory. They also reveal that firms can communicate assurance, functional, technical and social values of transparency and control to address consumer vulnerability.
Originality/value
This research makes the following contributions to the data privacy literature. The findings exhibit multidimensional and comprehensive conceptualizations of transparency and control, including user, firm and information perspectives. Additionally, the conceptual framework combines empirical insights from both experiencers and observers to offer an understanding of how transparency and control serve as justice mechanisms to effectively tackle the issue of unsanctioned transmission of personal information and subsequently address vulnerability. Lastly, the findings provide strategic approaches to communicating the value of transparency and control.

Abstract
Purpose
At present, research on the preparation of corrosion inhibitors using modified pyrimidine derivatives is still blank. The purpose of this study is to synthesize a new cationic mercaptopyrimidine derivative quaternary ammonium salt, known as DTEBTAC, that can be used as a corrosion inhibitor to slow down the metal corrosion problems encountered in oil and gas extraction processes.
Design/methodology/approach
A new corrosion inhibitor was synthesized by the reaction of anti-Markovnikov addition and nucleophilic substitution. The weight loss method was used to study the corrosion inhibition characteristics of synthetic corrosion inhibitors. Electrochemical and surface topography analyses were used to determine the type of inhibitor and the adsorption state formed on the surface of N80 steel. Molecular dynamics simulations and quantum chemistry calculations were used to investigate the synthetic corrosion inhibitor’s molecular structure and corrosion inhibition mechanisms.
Findings
The results of the weight loss method show that when the dosage of DTEBTAC is 1%, the corrosion rate of N80 steel in hydrochloric acid solution at 90? is 3.3325 g m-2 h-1. Electrochemical and surface morphology analysis show that DTEBTAC can form a protective layer on the surface of N80 steel, and is a hybrid corrosion inhibitor that can inhibit the main anode. Quantum chemical parameter calculation shows that DTEBTAC has a better corrosion inhibition effect than DTP. The molecular dynamics simulation results show that DTEBTAC has stronger binding energy than DTP, and forms a network packing structure through hydrogen bonding, and the adsorption stability is enhanced.
Originality/value
A novel cationic mercaptopyrimidine derivative quaternium-ammonium salt corrosion inhibitor was designed and provided. Compared with the prior art, the preparation method of the synthesized mercaptopyrimidine derivative quaternary ammonium salt corrosion inhibitor is simple, and the presence of nitrogen-positive ions, sulfur atoms and nitrogen-rich atoms has an obvious corrosion inhibition effect, which can be used to inhibit metal corrosion during oil and gas field exploitation. It not only expands the application field of new materials but also provides a new idea for the research and development of new corrosion inhibitors.
