Surface acoustic wave (SAW) sensors have attracted great attention worldwide for a variety of applications in measuring physical, chemical and biological parameters. However, stability has been one of the key issues which have limited their effective commercial applications. To fully understand this challenge of operation stability, this paper aims to systematically review mechanisms, stability issues and future challenges of SAW sensors for various applications.

This review paper starts with different types of SAWs, advantages and disadvantages of different types of SAW sensors and then the stability issues of SAW sensors. Subsequently, recent efforts made by researchers for improving working stability of SAW sensors are reviewed. Finally, it discusses the existing challenges and future prospects of SAW sensors in the rapidly growing Internet of Things-enabled application market.

A large number of scientific articles related to SAW technologies were found, and a number of opportunities for future researchers were identified. Over the past 20 years, SAW-related research has gained a growing interest of researchers. SAW sensors have attracted more and more researchers worldwide over the years, but the research topics of SAW sensor stability only own an extremely poor percentage in the total researc topics of SAWs or SAW sensors.

Although SAW sensors have been attracting researchers worldwide for decades, researchers mainly focused on the new materials and design strategies for SAW sensors to achieve good sensitivity and selectivity, and little work can be found on the stability issues of SAW sensors, which are so important for SAW sensor industries and one of the key factors to be mature products. Therefore, this paper systematically reviewed the SAW sensors from their fundamental mechanisms to stability issues and indicated their future challenges for various applications.

This study aims to examine how veganism is “seen” by young adult non-vegan consumers and how prevailing attitudes reinforce or challenge stigmas around veganism.

Photovoice methodology was used to explore young non-vegan consumers’ attitudes and beliefs towards veganism. Data was collected from students studying advertising at a major university in Australia, who produced images and narratives reflective of their own attitudes towards veganism. Polytextual thematic analysis of the resulting visual data was then undertaken to reveal the dominant themes underpinning participants’ attitudes. Participant narratives were then reviewed to confirm whether the ascribed meaning aligned with participants’ intended meaning.

Participant images were reflective of first, how they saw their world and their place within it, which showed the interplay and interconnectedness between humans, animals and nature, and second, how they saw vegans within this world, with both positive and negative attitudes expressed. Interestingly, vegans were simultaneously admired and condemned. By situating these attitudes along a spectrum of moral evaluation, bounded by stigmatisation and moral legitimacy, participants saw vegans as being either Radicals, Pretenders, Virtuous or Pragmatists. For veganism to become more widely accepted by non-vegans, there is an important role to be played by each vegan type.

This study offers a more nuanced understanding of how and why dissociative groups, such as vegans, become stigmatised, which has implications for messaging and marketing practices around veganism and associated products/services. Future research could use a similar methodology to understand why other minority groups in society are stereotyped and stigmatised, which has broader social implications.

This chapter highlights Freire's history and ideologies allow the text to act as in introduction work for those interested in looking at education from a Freireian perspective, and as such it also helps pull together the many aspects of Freire's life and ideas. These points are important because a lot of existing texts and journal articles tend to view Freire from very distinctive perspectives. For example, far and away his most popular text is Pedagogy of the Oppressed, but this chapter explores what he wrote about in the 20 other books and dozens of journal articles he wrote. Freire wrote about oppression in education, but also in government, by race and language, and throughout these explorations is a myriad idea about how oppression works, and why the oppressed let themselves be controlled by a minority. Highlighting these facts is a key starting point to the book.

This paper examines the US opera sector as a means for interrogating how varying forms of non-standard work shape gender inequality in the creative industries.

The authors draw on 16 seasons of opera production data from Operabase.com to conduct a gender-based exploratory data analysis of the key creative roles of conductor, director and designers, as well as the hiring networks through which teams are formed, at the 11 largest opera companies in the United States.

The authors find that women, as a group, experienced gender-based disadvantage across the key creative roles of opera production, but particularly in the artistic leadership roles of conductor and director. The authors also find that women's exclusion in the field is being further perpetuated by the sector's non-standard and overlapping employment structures, which impacts women practitioners' professional visibility and career opportunities.

The study can help organizations implement strategic hiring practices that acknowledge the relationship between gender inequality and varying forms of non-standard work with the aim of increasing women's representation.

This study work establishes the scale of gender inequality operating within a sector that has received minimal scholarly attention as a site of employment. The study analysis also offers important insight for the wider creative industries and highlights opportunities to redress gender inequality in other sectors where project-based work is prevalent.

In this chapter, I take a symbolic interactionist look at the anthropomorphic projections of 38 people in four large Canadian cities who report having encountered ghosts. As part of a larger project on perceived encounters with ghosts, I interviewed these people using audiotape, transcribed the interviews, and identified themes within them. Together, they mentioned 195 ghosts and described their appearances and actions. I identified anthropomorphic projections in four areas: (1) Physicality – pertaining to the bodies of the ghosts, (2) Relational – pertaining to kinship ties, e.g., mothers, fathers, grandmothers, (3) Rational – the ghosts' motivations and justifications, and (4) Affective – pertaining to the ghosts' emotions. These anthropomorphic projections were the respondents' efforts at sense making after having encountered what they believed to be phantasmal.

The purpose of this research is to determine the competitive advantages of higher education institutions (HEIs) and create a new methodology to rank universities according to the competitive advantages.

The research determines the competitive advantages of HEIs by analysing expert opinions through a semi-structured interview form, matches codes and themes to performance indicators using Saldana's two-cycle coding methods, evaluates content validity through Lawshe and reveals the item weights of the ranking with analytical hierarchy process (AHP). Simple additive weighting (SAW) and Technique for Order of Preference by Similarity (TOPSIS) methods were used for ranking universities.

Seven dimensions stand out in regard to what should be considered while ranking HEIs: research and publication, education, management, infrastructure, financial resources, human resources and social and economic contribution. Under the 7 dimensions, 69 indicators were determined.

The research provides a scientific reference point where HEIs can compare themselves with other HEIs regarding where they are in the sector, especially in terms of competitive advantages.

Although there are many different ranking methods that rank universities in the national and international literature, almost all these methods are largely based on the outputs of the university such as the number of publications, the number of patents, the number of projects, etc. A framework which ranks universities by considering different aspects of the institution, such as management, human resources and financial resources, has not been developed yet. In this respect, this research aims to fill this gap in the literature.

Paramedics became nationally registered in 2018 in Australia. Prior to this, there was no central regulation of the profession with reliance on organisational regulation through employers. As paramedics expanded their scope, role and range of employers, especially outside statutory agencies, there was increasing need to engage in professional regulation. Regulation is more than a legal and bureaucratic framework. The purpose of the paper states that the way paramedics interact with their new regulatory environment impacts and is influenced by the professionalisation of the discipline. Regulation also redefines their positionality within the profession.

Two mixed-method surveys were undertaken. A pre-registration survey occurred in the month prior to regulation commencing (N = 419) followed by the second survey 31 months later (N = 407). This paper reports the analysis of qualitative data from the post-registration survey and provides comparison to the pre-registration survey which has been previously reported. Analysis was undertaken using interpretive phenomenological analysis (IPA).

Themes from the pre-registration survey continued however became more nuanced. Participants broadly supported registration and saw it as empowering to the profession. Some supported registration but were disappointed by its outcome, others rejected registration and saw it as divisive and oppressive.

Paramedics are beginning to come to terms with increasing professionalisation, of which regulation is one component. Changes can be seen in professional identity and engagement with professional practice; however, this is nascent and is deserving of additional research to track the profession as it continues to evolve.

This study employs Stein Rokkan's methodological approach to analyse state formation in the Greater Middle East. It develops a conceptual framework distinguishing colonial, populist and democratic pacts, suitable for analysis of state formation and nation-building through to the present period. The framework relies on historical institutionalism. The methodology, however, is Rokkan's. The initial conceptual analysis also specifies differences between European and the Middle Eastern state formation processes. It is followed by a brief and selective discussion of historical preconditions. Next, the method of plotting singular cases into conceptual-typological maps is applied to 20 cases in the Greater Middle East (including Afghanistan, Iran and Turkey). For reasons of space, the empirical analysis is limited to the colonial period (1870s to the end of World War 1). Three typologies are combined into one conceptual-typological map of this period. The vertical left-hand axis provides a composite typology that clarifies cultural-territorial preconditions. The horizontal axis specifies transformations of the region's agrarian class structures since the mid-19th century reforms. The right-hand vertical axis provides a four-layered typology of processes of external intervention. A final section presents selected comparative case reconstructions. To the authors' knowledge, this is the first time such a Rokkan-style conceptual-typological map has been constructed for a non-European region.

Renewable energy infrastructure is an important asset class in the context of reducing global carbon emissions going forward. This includes solar power, wind farms, hydro, battery storage and hydrogen. This paper examines the risk-adjusted performance and diversification benefits of listed renewable energy infrastructure globally over Q1:2009–Q4:2022 to examine the role of renewable energy infrastructure in a global infrastructure portfolio and in a global mixed-asset portfolio. The performance of renewable energy infrastructure is compared with the other major infrastructure sectors and other major asset classes. The strategic investment implications for institutional investors and renewable energy infrastructure in their portfolios going forward are also highlighted. This includes identifying effective pathways for renewable energy infrastructure exposure by institutional investors.

Using quarterly total returns, the risk-adjusted performance and portfolio diversification benefits of global listed renewable energy infrastructure over Q1:2009–Q4:2022 is assessed. Asset allocation diagrams are used to assess the role of renewable energy infrastructure in a global infrastructure portfolio and in a global mixed-asset portfolio.

Listed renewable energy infrastructure was seen to underperform the other infrastructure sectors and other major asset classes over 2009–2022. While delivering portfolio diversification benefits, no renewable energy infrastructure was seen in the optimal infrastructure portfolio or mixed-asset portfolio. More impressive performance characteristics were seen by nonlisted infrastructure funds over this period. Practical reasons for these results are provided as well as effective pathways going forward are identified for the fuller inclusion of renewable energy infrastructure in institutional investor portfolios.

Institutional investors have an important role in supporting reduced global carbon emissions via their investment mandates and asset allocations. Renewable energy infrastructure will be a key asset to assist in the delivery of this important agenda for a greener economy and addressing global warming. Based on this performance analysis, effective pathways are identified for institutional investors of different size assets under management (AUM) to access renewable energy infrastructure. This will see institutional investors embracing critical investment issues as well as environmental and social issues in their investment strategies going forward.

This paper is the first published empirical research analysis on the performance of renewable energy infrastructure at a global level. This research enables empirically validated, more informed and practical decision-making by institutional investors in the renewable energy infrastructure space. The ultimate aim of this paper is to articulate the potential strategic role of renewable energy infrastructure as an important infrastructure sector in the institutional real asset investment space and to identify effective pathways to achieve this renewable energy infrastructure exposure, as institutional investors focus on the strategic issues in reducing global carbon emissions in the context of increased global warming.
