Abstract
Purpose
The purpose of this paper is to examine the use of a new feature reduction technique with novelty detection on vibration and acoustic‐emission sensors monitoring bearings mounted in the test benches of automotive manufacturers.
Design/methodology/approach
Signals from standard accelerometers and acoustic‐emission sensors were gathered from bearings operating under steady conditions on an accessory‐drive test bench. The bearings under test were subject to a variety of faults including fretting. These signals were processed and reduced to standard feature vectors, the dimensionality of which was reduced using a new principal‐component‐like technique optimized for novelty detection. The reduced data were analyzed with a novelty detection technique called the Support Vector Data Descriptor.
Findings
The classification results from these sensors, after being reduced with the proposed feature reduction technique, are substantially improved over those achievable with only standard novelty detection; nearly zero‐percent classification error was achieved.
Research limitations/implications
The feature reduction technique depends, in part, on the availability of the fault type in question – potentially violating the normal novelty detection assumption of limited abnormal data. This may require the manufacturer to gather real or simulated fault data prior to running tests.
Practical implications
Incipient faults may be detectable at a much earlier stage in a manufacturer's component failure analysis. Test engineers may use this technique to reliably automate the fault detection process and enable improved root‐cause analysis through the earlier identification of faults.
Originality/value
The application of the feature reduction technique will provide manufacturers and researchers with a new means of improving fault detection in machinery components.

Abstract
In this chapter, we develop and present the Multi-Perspective Multilevel Model of emotional labor in organizations. This model is based on three perspectives: (1) a service requirement, (2) an intra-psychic process, and (3) an emotional display, each involving five levels of analysis: within-person, between persons, in interpersonal exchanges, in groups, and across the organization as a whole. Our model is differentiated from earlier characterizations of emotional labor in that we propose that the phenomenon begins with energy generation instead of energy depletion; and is neither a one-way nor a one-by-one service episode. We further proffer that the intra-psychic processes embedded in emotional labor represent a form of social self-regulation that impacts across multiple levels within service organizations. We conclude by discussing the implications and limitations of our model for emotional labor research.

Abstract
Children are the primary group most affected by all sorts of social and political developments in a society, whether negative or positive. The disintegration of the social fabric, the destabilisation of a country and the breakdown of political and social security pose a greater threat to children and expose them to greater harm compared to other social strata. Children, whose family integrity in cities, villages and towns has been reduced to dust by the civil war that has raged in Afghanistan for over 40 years, are the most exposed to this violence. Millions of Afghan children have been deprived of modern educational opportunities. On the other hand, the children have been forced to bear the economic burden of the household due to the loss of the source of income for the families as the fathers died in terror attacks. Add to this the psychological problems suffered by the children, as well as the physical abuse of boys, a bitter and archaic picture emerges. In addition, girls are forced to be married off to influential older men, sometimes the age of their grandfathers, and boys are given weapons at an early age, only to be offered to unlawful organisations as fighters to be deployed in conflict zones after harsh and difficult training. This threatens the very nature of what human and children's rights stand for. In this study, using the figures and statistics from UNICEF, Afghanistan Independent Human Rights Commission and other institutions such situations of human rights and children's rights in this country are analysed.

Abstract
This chapter provides an overview of the inclusive education policies in Ghana and how these policies were developed toward fulfilling the 2030 Sustainable Development Goal Number 4. We start the chapter by introducing Ghana's demographics and awareness in disability, as well as the historical background in inclusive education. Next, we address the current state of Ghana's inclusive education by sharing the current policies and infrastructure that transforms special education schools into resource centers, promotes a learner-friendly environment, and serves as the legal foundation for private and public schools to implement inclusive education for all children. We further discuss the challenges imposed by the recent wave of the COVID pandemic on inclusive education, and the initiatives Ghana leadership enacted to provide a continuum of inclusive services for all children. We then conclude the chapter with implications and recommendations to stakeholders.

Abstract
Purpose
The purpose of this paper is to explore the antecedents and consequences of employee engagement (EE) in global research and Vietnamese business context.
Design/methodology/approach
This review was conducted in the following order: an integrative review for garnering drivers and outcomes of EE in global research, followed by a narrative review for selecting variables relevant to Vietnamese businesses.
Findings
In EE global research, a 3 × 3 findings framework was devised. Three antecedent clusters included the internal environment, job-related and employee-related factors. EE resulted in three outcome clusters: intra-role behaviors, extra-role behaviors and personal development and growth. In Vietnamese businesses, few studies existed on organizational learning and organizational support as EE antecedents, whereas turnover intention was examined the most as an EE outcome.
Research limitations/implications
The search was limited to EE-related peer-reviewed articles in Business Source Complete and Google Scholar. Literature on Vietnam EE was restricted to ProQuest Dissertations and Theses and Google Scholar because of a lack of literature availability on this topic in Business Source Complete.
Practical implications
Knowing that leadership, HR practices and working environment are important antecedents of EE in Vietnam (Table II) would prompt enterprise leaders and managers to improve the company’s conditions for engaging its employees. This is an important finding because Vietnamese businesses are suffering increasing turnover. Creating favorable organizational support evidenced via career growth opportunities, pay and benefits, company culture, job fit and effective management will stimulate employees to stay and engage.
Originality/value
This study emphasizes the organizational and employee factors in EE research and calls for combined research application to inform EE in Vietnamese businesses, thus providing ground for human resource development researchers and practitioners in their respective work.
