Abstract

Purpose

Adolescent mental health is a global concern. There is an urgent need for creative, multimedia interventions reflecting adolescent culture to promote mental health literacy and well-being. This study aims to assess the impact of a film-based intervention on adolescent mental health literacy, well-being and resilience.

Design/methodology/approach

A pretest-posttest intervention with a multi-methods evaluation was used. A convenience sample of ten schools facilitated students aged 15–17 years to engage in an online intervention (film, post-film discussion, well-being Webinar). Participants completed surveys on well-being, resilience, stigma, mental health knowledge and help-seeking. Five teachers who facilitated the intervention participated in post-implementation interviews or provided a written submission. Analysis included paired-t-test and effect size calculation and thematic analysis.

Findings

Matched pretest-posttest data were available on 101 participants. There were significant increases in well-being, personal resilience and help-seeking attitudes for personal/emotional problems, and suicidal ideation. Participants’ free-text comments suggested the intervention was well-received, encouraging them to speak more openly about mental health. Teachers similarly endorsed the intervention, especially the focus on resilience.

Originality/value

Intinn shows promise in improving adolescents’ mental health literacy and well-being. Film-based interventions may encourage adolescents to seek professional help for their mental health, thus facilitating early intervention.

Abstract

Within North American institutions of higher education, the sociopolitical construct of whiteness comprises an often implicit set of lessons that are reflected not only in policy and curricula but also in the teaching practices of faculty. Such lessons perpetuate white centricity and supremacy, at enormous costs to those who have been negatively racialized. Therefore, it is critical for white faculty to engage meaningfully with ongoing processes of self-reflection, self-education, and skill development so that they can contribute positively to the interrogation and disruption of whiteness in higher education. This chapter discusses seven processual considerations for white educators who seek to interrogate and disrupt the problem of whiteness in teaching and learning.

Abstract

Purpose

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.

Design/methodology/approach

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.

Findings

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.

Practical implications

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.

Originality/value

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.

Abstract

Purpose

The purpose of this study is to develop a conceptual model explicating the development of expatriate social capital and its influence on expatriate effectiveness in terms of knowledge transfer and adjustment. Drawing upon social capital theory and weak tie theory, we elucidate the process through which expatriate social capital facilitates expatriate knowledge transfer and adjustment via greater access of role information and social support.

Design/methodology/approach

This study reviews and distills research on expatriate social capital development and proposes a conceptual model of expatriate effectiveness and suggests potential research avenues for global mobility scholars.

Findings

This study contributes to the understanding of the development of expatriate social capital in the host country and its impacts on expatriate effectiveness as a process. With regard to expatriates’ social capital accumulation, this study also highlights the important but less-known role of accompanying spouse/family members as expatriates’ weak tie enablers. We articulate a framework that outlines the sources of social capital for expatriates and the processes through which social capital transmits (via expatriates’ access to role information and social support) and then enhances expatriate effectiveness. This conceptual model aims to establish a basic “roadmap” for use by practitioners and researchers.

Research limitations/implications

Before the proposed conceptual model can be theoretically refined or extended by future research, its veracity needs to be tested empirically. Although we do not incorporate “time,” “personal characteristics” and “context” in our model, we recognize their potential importance and urge future researchers to incorporate them in studying the role of social capital on expatriate effectiveness.

Practical implications

A conceptual model is presented that enables multinational corporations (MNCs) to map their current (and future) strategies to enhance expatriate effectiveness by further strengthening the expatriate social capital.

Originality/value

Drawing upon social capital theory and weak tie theory, this paper links various sources of expatriate social capital to expatriates’ access to role information and social support in supporting expatriate effectiveness. From this, several avenues of future research are drawn.

Abstract

Purpose

To illuminate the experience of working with students using the innovative pedagogical approach of dramaturgy, this pedagogy can more effectively address systemic bias within academia.

Design/methodology/approach

This paper is rooted in dramaturgical theory which suggests that how a person's identity or background is being constantly reshaped by their interactions with one another and the world around them. Within a classroom setting, it applies to contexts where group activities have a required performative aspect.

Findings

The authors found that taking a dramaturgical approach can be a very effective active learning technique within a one-shot information literacy instruction context.

Originality/value

Creative approaches to information literacy instruction often remain untried, and the combination of this work and the consideration of dramaturgical theory within the framework of inclusive pedagogy is a distinct contribution to the field.

This study aims to extend the pot life without altering the qualities and performance of the coating, which is important to increase when manufacturing polyurethane coatings.

Abstract

Purpose

This study aims to extend the pot life without altering the qualities and performance of the coating, which is important to increase when manufacturing polyurethane coatings.

Design/methodology/approach

An acrylic polyol from a mixture of different monomers of hydroxypropyl methacrylate, methacrylic acid, 2-ethylhexyl acrylate, methyl methacrylate and n-butyl methacrylate was prepared with different ratios of 2,4-pentanedione as a pot life extender. The reaction takes place in presence of di-tert-butyl peroxide as initiator with samples (T1–T7). The physical properties of prepared acrylic polyol were characterized. Then, coating polyurethane varnish was prepared from the prepared acrylic polyol with an aliphatic polyisocyanate in a 1:1 equivalent ratio of OH:NCO at room temperature, in presence of paint thinner (diluents/solvent) and dibutyltin dilaurate as a catalyst to give samples (T1C–T7C). This coating was evaluated via Fourier-transform infrared spectroscopy, drying time, hardness and gloss, distinctness of image and reflected image quality.

Findings

The coating has a prolonged pot life while still maintaining the other qualities, thanks to the greater 2,4-pentanedione content.

Originality/value

It is desired to have a paint which has a satisfactory pot life, short curing time and reduces many drawbacks such as inefficient working and deterioration of the paint before application.

This paper aims to investigate the effect of shear rate, concentration (4–20 kg/m3) and temperature (20°C–60 °C) on the apparent viscosity of apricot gum solutions.

Abstract

Purpose

This paper aims to investigate the effect of shear rate, concentration (4–20 kg/m3) and temperature (20°C–60 °C) on the apparent viscosity of apricot gum solutions.

Design/methodology/approach

Apparent viscosity has been measured using a rotational viscometer.

Findings

It has been observed that the shear stress and apparent viscosity values increase at high concentrations in the prepared apricot gum solutions. However, it is understood that the higher the temperature in the operation conditions, the lower the apparent viscosity results. Power-law is found the best-fitting model to illustrate the changes in temperature and concentration. According to the consistency coefficient and flow behavior indices, the apricot gum displayed shear-thinning behavior (pseudoplastic). The apricot gum is a polysaccharide with amino and uronic acids, according to Fouirer Transform Infrared Spektrofotometre spectra.

Practical implications

The results suggest that power-law model can be used to estimate the viscosity of apricot gum solutions at different temperatures and concentrations for applications for which flow behavior should be taken into account.

Originality/value

Exudate gums have good rheological properties and, therefore, are widely used in the food industry. Apricot gum is a biodegradable and abundant polysaccharide that enhances viscosity, stabilizes suspension or emulsion and improves the flow properties of foods. Different rheological models are used to investigate rheological properties. However, those models are time-independent to fit the experimental data.

Abstract

Purpose

This study aims to contribute to the enrichment of the literature by examining the impact of cross-cultural training on expatriates’ adjustment of Nigerian bankers on expatriate assignments in other African countries.

Design/methodology/approach

Data on cross-cultural adjustment from expatriate employees in five banks that collectively accounted for over 80 per cent of Nigerian banks with subsidiaries in other African were systematically selected for the investigation. This data was collected quantitatively via a survey instrument. Independent sample t-test, analysis of variance (ANOVA) and regression analysis were deployed in analyzing the data.

Findings

The study found that cross-cultural adjustment varied significantly across the different categories of gender, age, marital status, previous expatriate training, previous expatriate experience, and duration of expatriation. The study concludes that in order to attain higher levels of adjustment African banks and other organizations should provide a more comprehensive cross-cultural training program that mirrors the needs of employees following a detailed needs analysis. Also, the training must be sequential and not a one-off approach.

Originality/value

The literature though still nascent is largely focused on expatriate preparation and adjustment for expatriates moving from Western-to-western contexts and very little exists in the literature on how multinationals from Non-Western contexts like Africa prepare their staff for expatriation and its consequent impact on their adjustment. This study aims to enrich the literature by examining the impact of cross-cultural training on expatriates’ adjustment of Nigerian bankers on expatriate assignments in other African countries.

This paper aims to determine the impact of mentorship on the development of self-directedness among beginner teachers in their initial years of teaching.

Abstract

Purpose

This paper aims to determine the impact of mentorship on the development of self-directedness among beginner teachers in their initial years of teaching.

Design/methodology/approach

The researcher adopted a positivist paradigm to explore the situation of concern. Quantitative research was conducted, involving the collection and analysis of numerical data. Two closed-ended structured questionnaires were utilised, derived from the 40-item self-directed learning readiness scale (SDLRS) developed by Fisher and King, and a pre-determined questionnaire by Glazerman focused on the first-year teaching experience, induction and mentoring of beginner teachers.

Findings

Beginner teachers merely relying on the knowledge obtained from their studies is insufficient to achieve a satisfactory level of self-directedness when starting a teaching career. Most beginner teachers faced significant challenges in their early years of teaching due to the absence of mentoring support. In addition, most indicated that they resume their teaching duties and rely on their district for general support, guidance and orientation. Finally, the results have shown that mentoring positively impacts beginner teachers’ self-directedness.

Research limitations/implications

The first limitation was that this study was narrowed to one South Africa University part-time B.Ed honours students working as beginner teachers in different provinces at primary and secondary schools. As a result, the findings of this research might be interpreted by some critics as one-sided and not representative of the views of most beginner teachers in South Africa who are working. The second limitation of this study is the sample size. In this study, 222 responses were received. As a result, the findings of this research might be considered not representative of the target sample size.

Practical implications

The presence and effective implementation of mentoring programmes in schools can positively impact beginner teachers' professional development and retention during their first years of teaching.

Social implications

We contend that our research holds significance for international readership as it aims to garner attention towards potential research endeavours in diverse settings concerning mentorship programs for beginner teachers, specifically promoting self-directed learning. Our research offers opportunities to compare our findings with studies conducted in more comprehensive, comparative contexts and foster research possibilities in broader, contrasting contexts.

Originality/value

Based on the findings of this research, the availability and effective use of mentoring programmes would significantly affect beginner teachers' self-directedness, improve their retention rate and alleviate their teaching challenges. This study was the first research on the perceptions of the influence of mentoring on the self-directedness of beginner teachers.

Abstract

Purpose

This study addressed a relatively understudied process of school leadership: the principal-teacher conversation about instructional change. Two distinct conversation structures were examined: controlling conversation and transformative leadership conversation (TLC). Self-determination theory (SDT) was used to make the case that TLC is a better fit for instructional change than controlling conversation. Hypotheses were developed on the relationship between principal-teacher conversation and teacher trust in the principal, teacher autonomy and teacher vitality. These mental states were identified for empirical testing because of their influence on change processes.

Design/methodology/approach

The empirical study used a correlational research design with survey data. The data came from a random sample of 2,500 teachers from the population of certified teachers in a southwestern state in the USA. Useable survey responses were obtained from 1,615 teachers, for a response rate of 65 percent. Teachers in the sample averaged 15 years of teaching experience, with 7 years in their current school. Around 81% of teachers identified as female and 18 percent as male and 79% of teachers listed a racial identification as white. Hypotheses were tested in a path model using AMOS 28.0 with robust maximum likelihood (MLR).

Findings

As hypothesized, TLC had moderate to strong positive relationships with teacher trust in the principal, teacher autonomy and teacher vitality. Controlling conversation had small, negative relationships with teacher trust in the principal and teacher autonomy. Controlling conversation was not related to teacher vitality in the path analysis. Compared with controlling conversation, TLC had stronger relationships with teacher mental states.

Originality/value

The results of this study begin to reveal useful evidence on the inherent social-psychological mechanisms active in principal-teacher conversations. With results indicating that conversation structure has consequences for positive teacher mental states, the study directs attention to a ubiquitous yet understudied leadership process.
