Abstract

In smart cities striving for innovation, development, and prosperity, hydrogen offers a promising path for decarbonization. However, its effective integration into the evolving energy landscape requires understanding regional intricacies and identifying areas for improvement. This chapter examines hydrogen transport from production to utilization, evaluating technologies’ pros, cons, and process equations and using Analytic Hierarchy Process (AHP) as a Multi-Criteria Decision-Making (MCDM) tool to assess these technologies based on multiple criteria. It also explores barriers and opportunities in hydrogen transport within the 21st-century energy transition, providing insights for overcoming challenges. Evaluation criteria for hydrogen transport technologies were ranked by relative importance, with energy efficiency topping the list, followed by energy density, infrastructure requirements, cost, range, and flexibility. Safety, technological maturity, scalability, and compatibility with existing infrastructure received lower weights. Hydrogen transport technologies were categorized into three performance levels: low, medium, and high. Hydrogen tube trailers ranked lowest, while chemical hydrides, hydrail, liquid organic hydrogen carriers, hydrogen pipelines, and hydrogen blending exhibited moderate performance. Compressed hydrogen gas, liquid hydrogen, ammonia carriers, and hydrogen fueling stations demonstrated the highest performance. The proposed framework is crucial for next-gen smart cities, cutting emissions, boosting growth, and speeding up development with a strong hydrogen infrastructure. This makes the region a sustainable tech leader, improving air quality and well-being. Aligned with Gulf Region goals, it is key for smart cities. Policymakers, industries, and researchers can use these insights to overcome barriers and seize hydrogen transport tech opportunities.

Abstract

The reasons why a coating is selected as suitable for use on a pipeline would normally depend upon two major factors. Firstly, the performance of the available coatings has to be evaluated according to their technical characteristics. Secondly, price, which is more often influenced by application techniques rather than actual material cost.

Abstract

The chemical reprocessing of irradiated nuclear fuel involves the handling of highly radioactive and often hot or highly corrosive solutions, usually containing nitric acid. This demands plant constructed to a high standard of integrity from suitably resistant materials. The difficulty of carrying out maintenance or repair of active plant which fails due to corrosion means that an adequate corrosion allowance, based on reliable data, must be included at the design stage. The data on which to base the allowance are gathered from small‐and rig‐scale laboratory experiments where coupons or vessels, tubing, etc fabricated from the candidate material(s) are exposed to a simulated process environment. This is backed up whenever possible by corrosion data accruing from the operation of existing plants and by exposure of specimens to the actual plant environment followed by metallographic examination. The constructional materials most commonly used in reprocessing plants are austenitic grades of stainless steel along with smaller quantities of refractory metals like titanium. This, unsurprisingly, is in line with current practices in the nitric acid manufacturing industry.

Abstract

Purpose

Research on Science parks (SPs) has attracted a growing interest in the last decades. This widespread innovation policy initiative pursues technology-based industrial and entrepreneurial growth through business development and technology transfer across new and mature firms. Despite the common agreement on SPs' potential benefits, literature have showed mixed results regarding the performance of SPs. To explain this findings, current research pointed out at the lack of a common guiding framework. To cover this knowledge gap, this manuscript proposes an integrative definition and research model together with a multidimensional measurement instrument suitable to encompass the diverse reality of this global phenomenon.

Design/methodology/approach

Based on a systematic literature review of 281 indexed journal articles published between 1990 and 2018, the paper provides an integrative framework of enabling factors of SPs' performance.

Findings

The results illustrate an integrative conceptual framework of SPs that allows further comparison and generalization of research. At the same time, this manuscript provides valuable insights for managers and entrepreneurs as it conveys a standardized view of SPs' internal context useful for benchmarking.

Originality/value

Grounded in the resource-based view (RBV), the paper conducts a thorough literature review to develop an integrative research model featuring three value streams: physical infrastructures, formal links and support services. In addition, a multidimensional measurement tool to operationalize these three dimensions is proposed.

Abstract

Purpose

This study aims at investigating the indirect effect of soft skills on career engagement through the role of psychological capital (PsyCap) in different age groups. The social cognitive theory (SCT) and job demands-resource model (JD-R) were employed to explain the effect of perceived skill mastery on PsyCap and career engagement.

Design/methodology/approach

The data were collected from 707 high school students, 150 university students and 165 employees using a three-wave data collection technique. This study measured soft skills, PsyCap and career engagement at different age groups (i.e. high school students, university students and employees). The data were analysed using a moderated-mediation technique.

Findings

The results showed that soft skills positively influenced PsyCap and eventually increased career engagement in all age groups. However, the effect was stronger for students (both in high school and university) than employees in the workplaces. Unlike most students, employees related soft skills to performance. Regardless of the effect on performance, students would be more likely than employees to perceive soft skill mastery as a source of efficacy.

Research limitations/implications

First, the education system should direct more attention to developing students' non-cognitive skills. Second, people should understand that their career advancement continues in the workplace context. Organizations can foster employees' soft skills by providing more opportunities to develop new skills.

Originality/value

This study sheds light on the importance of soft skills beyond academic and workplace performance. This study is among the few empirical investigations that reveal career engagement factors across different career development stages.

Abstract

Purpose

The main purpose of this work is to evaluate the different psychological impacts of two initial verbal recovery strategies (gratitude vs empathetic apology) on the consumers' loyalty after a service failure. The proposed theoretical model also appraises the mediating role of two emotional responses (consumer forgiveness, consumer anger) and consumer self-esteem and the moderating role of self-oriented perfectionism.

Design/methodology/approach

Two studies (i.e. an experimental design and a field study) are considered for this investigation to assess the effectiveness of gratitude expression versus empathetic apology on post-recovery loyalty and test the effects of mediators and the moderator applied between the verbal recovery strategies and post-recovery loyalty.

Findings

The results of Study 1 revealed the supremacy of gratitude to empathetic apology in maintaining consumers' loyalty after service failure recovery. The better impact of gratitude expressed in increasing post-recovery loyalty is mediated through the elevation of consumers' forgiveness, the reduction of consumers' anger and consumers' self-esteem. The findings of Study 2 indicated that gratitude increases more post-recovery loyalty through individuals with a high level of self-oriented perfectionism.

Research limitations/implications

Future research could examine other service failure situations, different types of service recovery, mediators or moderators, which contribute to the service marketing literature.

Practical implications

After a service failure, using gratitude expressions to consumers often makes them feel better and more valuable.

Originality/value

This work increases service providers' knowledge in using proper expressions after a service failure to help elevate consumers' positive reactions resulting in maintaining their loyalty.

Abstract

Purpose

The purpose of this paper is to focus on the effects of career development and guidance among students (age 17-23) enrolled in higher education in The Netherlands. First the paper explores whether the development of career competencies contribute to career identity, learning motivation, certainty of career choice and drop out, and also whether the learning environment affects these variables. In the study, four career competencies are identified: career reflection (reflective behavior), work exploration (exploring behavior), career action (pro-active behavior) and networking (interactive behavior). Aspects of the learning environment that are taken into account are practice- and inquiry-based curriculum and career guidance conversations.

Design/methodology/approach

A questionnaire-based study was carried out among 4,820 students and 371 (school) career counsellors in 11 universities.

Findings

The results show that career competencies are related to learning motivation, career identity, certainty of career choice and drop out threat. The learning environment also contributes to these outcome variables. Students who participate in a practice-based and inquiry-based curriculum, and who have helping conversations about their study with their teachers, feel more motivated for learning, are more certain of their career choice and are less likely to quit their study.

Research limitations/implications

A limitation of this study is that, due to the cross-sectional design with no control group, no strong evidence for effectiveness can be presented. Moreover, the lack of well validated instruments limits the value of the results. The explained variance of the outcome variables, however, does indicate that there are relationships between career competencies and career learning environment on one hand, and career identity, learning motivation and certainty of choices on the other.

Practical implications

Constructing and attributing meaning when engaging in these dialogues is of central importance; the development of personality traits and qualities only takes place when those learning find the content meaningful (and that is something quite different than content being considered “necessary”). In order to achieve such a learning environment within the dominant educational culture, transformative leadership is essential. Such leadership, however, is rare in Dutch universities of applied sciences until now.

Social implications

Universities are increasingly acknowledging that they have a strong responsibility to guide students not only in their academic growth, but also in their career development. Universities – and especially universities of applied sciences – cannot leave this task to the public or private sector for two key reasons. First, universities are funded by the government and are therefore expected to prepare their students adequately for life in our individualized society as well as for the labor market. In the second place because organizations in the private and public sector often lack the knowledge and the motivation to guide young people on their career paths.

Originality/value

A limitation found in the research, as well as in actual career interventions in schools, is that they focus on change in students’ knowledge, attitudes and decision-making skills, while students’ behaviors are not examined. Hughes and Karp (2004) maintain that research should focus on exploring the relationships between guidance interventions and positive students’ behavioral outcomes. Therefore, the paper concentrates – in search of the influence of school-based career interventions – not on decision-making skills, attitudes or knowledge but on actual career behavior, i.e. career competencies of students.

Abstract

Purpose

Psychotherapy and clinical supervision outcomes are influenced by client and supervisee factors, one of which is cultural identity. Those with diverse racial and ethnic minoritised identities often experience disparities in therapy outcomes. Therapists and supervisors need to be responsive to the identity of those they support. The multicultural orientation (MCO) framework is an emerging concept in psychotherapy and clinical supervision that may offer these practitioners a framework to be responsive.

Design/methodology/approach

A preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews was conducted. Six databases, PubMed, Scopus, Embase, Academic Search Complete, Web of Science and PsychInfo, were searched for peer-reviewed literature published in English between the years 2000 and 2023.

Findings

A total of 1,553 sources were identified, of which (n = 42) are included in this review. Findings suggest that MCO is still in its infancy as applied to therapy and clinical supervision. Most of the research has been conducted in America, using quantitative methodologies with white western populations. Cultural humility is the most studied MCO pillar, and variables such as reductions in psychological stress, the working alliance and microaggressions are reported on as outcomes. MCO applied to the group therapy process is an emerging finding of interest. However, more research is needed, especially experiential designs across different and diverse populations and contexts.

Originality/value

MCO is an emerging therapy and clinical supervision process that has the potential to improve the outcomes for therapy clients and supervisees. Further research is needed to replicate current studies, and further research with diverse populations, countries and contexts should be undertaken as a priority.

Abstract

This paper employs a Generalised Autoregressive Conditional Heteroske‐dasticity in Mean (GARCH‐M) model to consider the effect of macroeconomic factors on Australian property returns over the period 1985 to 2002. Three direct (office, retail and industrial property) and two indirect (listed property trust and property stock) returns are included in the analysis, along with market returns, short, medium and long‐term interest rates, expected and unexpected inflation, construction activity and industrial employment and production. In general, macroeconomic factors are found to be significant risk factors in Australian commercial property returns. However, the results also indicate that forecast accuracy in these models is higher for direct office, listed property trust and property stock returns and that the persistence of volatility shocks varies across the different markets, with volatility half lives of between five and seven months for direct retail and industrial property, two and three months for direct office property and less than two months with both forms of indirect property investment.

Abstract

Purpose

The purpose of this study is to present evidence as to whether the use of gold or silver can be justified as an asset to hedge against policy uncertainty and COVID-19 in the Chinese market.

Design/methodology/approach

By using a GARCH model with a generalized error distribution (GED), this study specifies that the gold (or silver) return is a function of a set of economic and uncertainty variables, which include volatility from interest rate innovation, a change in economic policy uncertainty (EPU), a change in geopolitical risk (GPR) and volatility due to pandemic diseases, while controlling for stock market returns, inflation rates, economic growth and the Chinese currency value.

Findings

This study employs monthly data of gold and silver prices over the period from January 2002 to August 2021 to examine hedging behavior. Estimated results show that the gold return is positively correlated to the stock return and a rise in uncertainty from economic policy innovation, geopolitical risk, volatility due to US interest rate innovation as well as COVID-19 infection. This result suggests that gold cannot be used to hedge against a stock market decline, but can be used to hedge against uncertainty in general. However, the silver return only responds positively to a rise in uncertainty from the inflation rate and geopolitical risk. Evidence shows that silver returns are negatively correlated with stock returns, and display hedging characteristics. However, the evidence lacks statistically significance during the COVID-19 period, suggesting that the role of silver as a safe-haven asset against stock market turmoil is weak for this time period.

Research limitations/implications

More general nonlinear specifications can be developed. The tests may include different measures of uncertainty that interact with each other or with the lagged error terms. An implication of the model is that gold can be used to hedge against a broad range of uncertainties for economic policy change, political risk and/or a pandemic. However, the use of gold as an asset to hedge against a stock downturn in Chinese market should be done with caution.

Practical implications

This study has important policy implications as regards a choice in assets in formatting a portfolio to hedge against uncertainty. Specifically, this study presents empirical evidence on gold and silver return behavior and finds that gold returns respond positively to heightened uncertainty. Thus, gold is a good asset to hedge against uncertainty arising from policy innovations and infectious disease uncertainty.

Social implications

This paper provides insightful information on the choice of assets toward hedging against risk in the uncertainty market conditions. It provides information to investors and policy makers to use gold price movements as a signal for detecting the arrival of uncertainty. This study also provides information for demanding a risk premium for infectious disease.

Originality/value

This study empirically analyzes and verifies the role that gold serves as a safe haven asset to hedge against uncertainty in the Chinese market. This paper contributes to the literature by presenting evidence of risk/uncertainty premiums for holding gold against various sources of uncertainty such as economic policy uncertainty, geopolitical risk and equity market volatility due to US interest rate innovation and/or COVID-19. This study finds evidence that supports the use of a nonlinear specification, which demonstrates the interaction of uncertainty with the lagged change of infectious disease and helps to explain the gold/silver return behavior. Further, evidence shows that the gold return is positively correlated to the stock return. This finding contrasts with evidence in the US market. However, silver returns are negatively correlated with stock returns, but this correlation becomes insignificant during the period of COVID-19.
