Abstract

Purpose

Previous research demonstrates a consistent association between the media and body and eating related issues in children. Recent research has highlighted a role for “fat talk” to describe discourses around body size and food. One key source of media information is Disney animation films, yet to date no research study has explored the verbal content of this genre.

Design/methodology/approach

The present study used a content analysis to examine fat talk in Disney animation films (1937–2021; n = 53) with a focus on the frequency of fat talk, changes over time and differences between the genders and heroic statuses of the givers and receivers of fat talk. Fat talk was defined as relating to both body size and food and could be either positive or negative.

Findings

Results revealed that there was more negative than positive fat talk per film; no significant changes over time; males were the givers of significantly more positive and negative fat talk than females and were also the receivers of more negative fat talk; good characters were the givers and receivers of more positive and negative fat talk and more self-directed negative fat talk than bad characters.

Practical implications

The results are discussed in terms of possible legislation and parenting interventions to minimise the harm of this genre on young children.

Originality/value

Disney animation films may not be as benign as often thought.

Abstract

Purpose

The need for precise synthesis of customized designs has resulted in the development of advanced coating processes for modern nanomaterials. Achieving accuracy in these processes requires a deep understanding of thermophysical behavior, rheology and complex chemical reactions. The manufacturing flow processes for these coatings are intricate and involve heat and mass transfer phenomena. Magnetic nanoparticles are being used to create intelligent coatings that can be externally manipulated, making them highly desirable. In this study, a Keller box calculation is used to investigate the flow of a coating nanofluid containing a viscoelastic polymer over a circular cylinder.

Design/methodology/approach

The rheology of the coating polymer nanofluid is described using the viscoelastic model, while the effects of nanoscale are accounted for by using Buongiorno’s two-component model. The nonlinear PDEs are transformed into dimensionless PDEs via a nonsimilar transformation. The dimensionless PDEs are then solved using the Keller box method.

Findings

The transport phenomena are analyzed through a comprehensive parametric study that investigates the effects of various emerging parameters, including thermal radiation, Biot number, Eckert number, Brownian motion, magnetic field and thermophoresis. The results of the numerical analysis, such as the physical variables and flow field, are presented graphically. The momentum boundary layer thickness of the viscoelastic polymer nanofluid decreases as fluid parameter increases. An increase in mixed convection parameter leads to a rise in the Nusselt number. The enhancement of the Brinkman number and Biot number results in an increase in the total entropy generation of the viscoelastic polymer nanofluid.

Practical implications

Intelligent materials rely heavily on the critical characteristic of viscoelasticity, which displays both viscous and elastic effects. Viscoelastic models provide a comprehensive framework for capturing a range of polymeric characteristics, such as stress relaxation, retardation, stretching and molecular reorientation. Consequently, they are a valuable tool in smart coating technologies, as well as in various applications like supercapacitor electrodes, solar collector receivers and power generation. This study has practical applications in the field of coating engineering components that use smart magnetic nanofluids. The results of this research can be used to analyze the dimensions of velocity profiles, heat and mass transfer, which are important factors in coating engineering. The study is a valuable contribution to the literature because it takes into account Joule heating, nonlinear convection and viscous dissipation effects, which have a significant impact on the thermofluid transport characteristics of the coating.

Originality/value

The momentum boundary layer thickness of the viscoelastic polymer nanofluid decreases as the fluid parameter increases. An increase in the mixed convection parameter leads to a rise in the Nusselt number. The enhancement of the Brinkman number and Biot number results in an increase in the total entropy generation of the viscoelastic polymer nanofluid. Increasing the strength of the magnetic field promotes an increase in the density of the streamlines. An increase in the mixed convection parameter results in a decrease in the isotherms and isoconcentration.

Abstract

Purpose

The main objective of this paper is twofold: to analyse the progress of a research stream concerning expatriate academics in the last four decades and to make recommendations for further studies in this field.

Design/methodology/approach

In this study, the systematic literature review (SLR) concerning expatriate academics was applied. The search embraced the period from 1980–2022. The review was performed in two interdisciplinary electronic databases: Web of Science and Scopus. The selection process of papers was conducted in steps, as recommended by the PRISMA protocol. The total pool of articles received after the exclusion criteria was 110. The content of each paper was thus extracted and categorised in Excel file: author, year of publication, tittle of article, journal, theory applied, research method, sample size, country/field of investigation.

Findings

For almost three decades this topic was almost absent in the literature of the subject. The most active publication period started from 2009 and since then there have been two “waves” of published articles devoted to expatriate academics: 2009–2014 and 2017–2021. The significant number of studies appeared in Journal of Global Mobility followed by Personnel Review, IJHRM, Higher Education. The thematic analysis revealed six themes which have been already researched on expatriates academics: (1) motives, (2) adjustment, (3) job factors and work outcomes, (4) academic missions, (5) academic career, (6) women and men in academia.

Practical implications

Practitioners and university management might find this article useful as the article allows to manage this pool of international academics more efficiently with mutual benefits for expatriates and organisations. This study may assist the university authorities to develop systemic approach to attract foreign academics; adjust the same in work and culture domain through effective training; support in organisational, financial and career field; create the performance criteria of expatriate work related to three missions: research, teaching and service; introduce metrics and indicators to evaluate the contribution and work outcomes of foreign scientists into the host university.

Originality/value

This review shows that there are many new perspectives and models through which the academic expatriation can be analysed. This paper gives an insight into the academic literature on academics expatriates. The paper is innovative and has contributed to research by doing an SLR in a new area (academic expats) and tackling all the areas that has been covered by academic research so far. New research directions have been recommended for future research, to open the field further.

Abstract

Purpose

In recent years, using aberration-corrected transmission electron microscopy, the authors have achieved precisely detecting the structural evolution of passive film as well as its interface zone at atomic scale. The purpose of this paper aims to make a brief review to show the authors’ new understanding and perspective on the issue of critical factors determining stability of passive film of Fe-Cr alloy.

Design/methodology/approach

The introduction of single crystal enabled the authors to obtain a distinct metal/passive film interface and better characterize the structure of the interface region. The authors use aberration-corrected TEM to conduct cross-sectional observation and directly capture the details across the entire film at a high spatial and energy resolution.

Findings

Apart from the passive film itself, the interface zone, including metal/film (Me/F) interface and the adjacent metal side, is also the site which is attacked. Accordingly, the nature of the interface zone, such as microstructure, composition and atomic configuration, is one of the critical factors determining the stability of passive film.

Originality/value

Deciphering the critical factors determining the stability of passive film is of great significance and has been a fundamental issue in corrosion science. Great attention has been paid to the nature of the passive film itself. In contrast, the possible role of the interface between the passive film and the metal is rarely taken into account. Based on the advanced analytical tool with high spatial resolution, the authors have specified the significant role of interface structures on the macro-scale stability of passive film.

Abstract

Purpose

The purpose of this study is to investigate when and why supervisor negative feedback is associated with employees' job performance via two different pathways (i.e. emotion-focused coping and problem-focused coping) and to introduce proactive personality as a moderator.

Design/methodology/approach

Time-lagged data were collected using a field survey research design. Participants included 389 dyads of employees and their direct supervisors from five companies in China.

Findings

Supervisor negative feedback can lead to employees' emotion-focused coping, which in turn impairs their job performance. Meanwhile, supervisor negative feedback can trigger employees’ problem-focused coping, which subsequently promotes their job performance. Furthermore, proactive personality moderates the indirect effect of supervisor negative feedback on employee performance through emotion-focused coping.

Originality/value

This study explored the double-edged effects of supervisor negative feedback on employee job performance from a coping strategy perspective and investigated how proactive personality influences the choice of coping strategies.

Abstract

Purpose

The reasons for and experiences during migration, as well as additional stressors in the new host country, may give rise to mental health problems and additional need for public services. The purpose of the study was to investigate factors related to service utilization among newly arrived refugee youth.

Design/methodology/approach

Cross-sectional data were gathered in Sweden where 37 youth aged between 19 and 23 reported on factors related to service utilization, encompassing health-care and support services in school. These factors included predisposition (demographic), need (migration status and mental wellbeing) and enablement (living situation). Service utilization was estimated using multiple logistic regression analysis.

Findings

About a fourth of the sample used psychosocial services. Use of general support was more common. Neither predisposing, need nor enabling factors were associated with the use of psychosocial or general health-related services.

Originality/value

Self-reported factors related to use of health-related services have previously not been investigated for refugee youth, which is important in assuring access to appropriate services for this exposed youth population.
