Abstract

Purpose

To design and optimize the traditional aluminum gallium nitride/gallium nitride high electron mobility transistor (HEMT) device in achieving improved performance and current handling capability using the Synopsys’ Sentaurus TCAD tool.

Design/methodology/approach

Varying material and physical considerations, specifically investigating the effects of graded barriers, spacer interlayer, material selection for the channel, as well as study of the effects in the physical dimensions of the HEMT, have been extensively carried out.

Findings

Critical figure-of-merits, specifically the DC characteristics, 2DEG concentrations and mobility of the heterostructure device, have been evaluated. Significant observations include enhancement of maximum current density by 63 per cent, whereas the electron concentration was found to propagate by 1,020 cm−3 in the channel.

Practical implications

This work aims to provide tactical optimization to traditional heterostructure field effect transistors, rendering its application as power amplifiers, Monolithic Microwave Integrated Circuit (MMICs) and Radar, which requires low noise performance and very high radio frequency design operations.

Originality/value

Analysis in covering the breadth and complexity of heterostructure devices has been carefully executed through extensive TCAD modeling, and the end structure obtained has been optimized to provide best performance.

Abstract

Purpose

Drawing on social information processing theory and work-as-calling theory, this study explores the impact of mentoring within the Chinese context – which encompasses the roles of both mentors and senior mentees – on the calling and turnover intention of junior mentees in the hospitality industry.

Design/methodology/approach

Survey questionnaires were administered to collect 222 valid responses from frontline hotel employees in China. Partial least squares structural equation modeling (PLS-SEM) was adopted to test the hypotheses. We further conducted several post hoc interviews to gain a deeper understanding of the relationships examined.

Findings

Chinese mentoring positively affects mentees’ perceiving and living a calling, which in turn reduces their turnover intention. Junior mentees’ liking of their senior mentees further amplifies the negative effect of living a calling on their turnover intention.

Originality/value

This study enriches the literature on calling by exploring the antecedents of perceiving a calling and the boundary conditions that enhance the effect of living a calling on turnover intention. Additionally, our study highlights the unique aspect of Chinese mentorship as resembling a family-like relationship, a characteristic shaped by the pervasive influence of Confucianism in China, which enriches the existing literature on mentorship studies.

Abstract

Teachers are an adaptive group of professionals and in this chapter, we explore the ways that teachers can develop themselves as leaders, even in the absence of strong support or leadership. We explore the manner that these skill sets and strengths can be cultivated, providing lived examples of how the authors have developed themselves. The ways that teachers can follow in the footsteps of the authors is outlined in clearly defined steps. By drawing on previous literature, we provide seven strong claims of developing middle leadership knowledge and skill sets beyond your school. Much of this development and community development work that develops and sharpens leadership skills can be explored through online fora and social media tools. These tools allow skill development, professional learning, and exposure to a broad range of education stakeholders and groups; for future pathways in school leadership roles and leading beyond school gate.

Abstract

Services for adults with learning disabilities are currently based on the promotion of four key principles: rights, independence, choice and social inclusion. This paper will argue that, while these principles are welcome, they need to be balanced against a fifth principle ‐ that vulnerable adults should be adequately protected against the risk of abuse. It will draw on both recent high‐profile cases of violence and abuse against people with learning disabilities and research evidence to explore whether current plans to transform adult social care through the use of self‐directed support and individual budgets offer a safe future.

Abstract

Purpose

On the verge of what has been hailed as the next technological revolution, the purpose of this paper is to examine scientific and popular definitions of the social robot, reflecting on how expert and lay spheres of knowledge interact. Drawing on social representations theory, this paper aims to elucidate how social robots are named and classified, and to examine the dynamics contributing to their definition.

Design/methodology/approach

Scientific and popular definitions of the social robot were investigated by conducting: a systematic review of relevant articles published from 2009 to 2015 in the International Journal of Social Robotics; an analysis of the definitions retrievable from the scientific literature using Google Scholar; and an assessment of the interest in the public sphere, and of the popular definitions retrievable online (by inputting “social robot” in Google Trends, and in Google).

Findings

Scientific definitions of the social robot adopt two strategies, one drawing on and merging previous definitions, the other proposing new, visionary, forward-looking definitions. Popular online definitions of social robots attribute new emotional, linguistic and social capabilities to their physical body.

Research limitations/implications

The findings need to be confirmed by further research, given the limited size of the data sets considered, and the distortions in the data due to filters and the opacity of the online tools employed.

Originality/value

Both scientific and non-scientific definitions see social robots as being capable of interacting with and working for humans, but attribute them a different degree of (functional or full) autonomy. In future, any controversy over the connotation of social robots is likely to concern their sociality and autonomy rather than their functionality.

Abstract

Significantly more young people who have learning disabilities suffer from mental health problems than the general population for this age group (Borthwick‐Duffy, 1994, Emerson & Hatton, 2007). However, for a number of reasons these mental health problems are not identified early. Tier one staff who support people with learning disabilities are often unaware of the need to promote positive mental health or where to go locally for more advice and support if they are concerned. The CANDLE resource aims to provide accessible material that can be used in a range of ways, across a number of services and settings, to support these young people with their mental health.

Abstract

In the 1970s and 1980s, studies of the unpaid household and family labor of upper-class women linked this labor to class reproduction. In recent years, however, the topic of class has dropped out of analyses of unpaid labor, and such labor has been ignored in recent studies of elites. In this chapter, drawing primarily on 18 in-depth interviews with wealthy New York stay-at-home mothers, we look at what elite women’s unpaid labor consists of, highlighting previously untheorized consumption and lifestyle work; ask what it reproduces; and analyze how women themselves interpret and represent it. In the current historical moment, elite women face not only the cultural expectation that they will work for pay, but also the prominence of meritocracy as a mechanism of class legitimation in a diversified upper class. In this context, we argue, elite women’s unpaid labor serves to reproduce “meritocratic” dispositions of children rather than closed, homogenous elite communities, as identified in previous studies. Our respondents struggle to frame their activities as legitimate and productive work. In doing so, they not only resist longstanding stereotypes of “ladies who lunch” but also seek to justify and normalize their own class privileges, thus reproducing the same hegemonic discourses of work and worth that stigmatize their unpaid work.

Abstract

Purpose

This study explores how virtual learners perceive the use of humor in instructor-developed videos and their other factors for learning effectiveness in an online course.

Design/methodology/approach

The study adopted a set of qualitative methods flowing from lesson study, to pilot study, to self-declaration of a learning style, to semi-structured interviews. Through the process, 142 undergraduate business students from the same online course, of different learning styles, discussed their perspectives on the instructor's use of humor and their learning preferences in online situations. Thematic analysis was performed.

Findings

First, humor is deemed harmless, but its value is perceived at different degrees among the four styles of adult learners for their benefit of learning motivation toward an online course. Second, four common themes that respond to learning effectiveness online are addressed.

Research limitations/implications

Similar studies with additional samples, including students in other countries, in different age groups and/or on different online courses, are encouraged to strengthen the current findings.

Practical implications

The results provide evidence to school administrators, course developers and instructors on the importance of using a diverse pedagogy in online education. To motivate virtual learners, being humorous from instructors proves insufficient but developing the course with all respective features for different learners' styles is a clue.

Originality/value

It is among the first studies contextualizing a differential relationship between humor and learners' styles as well as evaluating the effectiveness of an online course from the learning-style standpoint.
