Chapter 21 presents and synthesizes research findings related to various aspects of locomotor economy during the childhood and adolescent years. Because the majority of research has been conducted on walking and running, the material presented in this chapter will focus exclusively on these modes of gait. It concludes by proposing future research directions to guide sport scientists, coaches, and clinicians in their quest to understand the factors responsible for efficient locomotion in children, improve the athletic performance of youngsters, and enhance the functional mobility and quality of life of physically challenged youth.

Published quality of life (QOL) studies in Hong Kong indexed in the major databases were reviewed. Several observations are highlighted from this review. First, most of the published studies were empirical studies involving data collection. Second, there are more micro studies utilizing individual QOL indices than macro studies using societal indicators. Third, most studies addressed personal well-being, followed by studies on family well-being and societal well-being. Fourth, the studies were predominantly quantitative in nature. Fifth, most of the studies were based on adults and comparatively fewer studies were based on children and adolescents. Sixth, most studies were based on populations with special needs, followed by studies based on the general population, helping professionals, and caregivers. Seventh, most studies used measures of QOL rather than developed QOL measures. Finally, QOL data in Hong Kong were seldom compared with those in other places. The gaps on QOL studies in Hong Kong and future research directions are discussed.

PurposeThe current climate of higher education, the implementation of the Workforce Opportunity and Innovation Act, and the 2017 merger of accrediting bodies have created changes within the field of rehabilitation. These changes must be appropriately addressed in order to fortify a profession that has long been instrumental in ensuring that individuals with disabilities are able to achieve a satisfactory quality of life.MethodsThis study was designed to provide current undergraduate rehabilitation education (URE) information to the field for discussion and planning purposes.ResultsThis research represents the results of a survey of URE program coordinators (n = 26) on the current state of their programs and programmatic needs.ConclusionRecommendations for current URE programs and future research directions are provided.

An opportune early diagnosis of Alzheimer’s disease (AD) would help to overcome symptoms and improve the quality of life for AD patients. Research studies have identified early manifestations of AD that occur years before the diagnosis. For instance, eye movements of people with AD in different tasks differ from eye movements of control subjects. In this review, we present a summary and evolution of research approaches that use eye tracking technology and computational analysis to measure and compare eye movements under different tasks and experiments. Furthermore, this review is targeted to the feasibility of pioneer work on developing computational tools and techniques to analyze eye movements under naturalistic scenarios. We describe the progress in technology that can enhance the analysis of eye movements everywhere while subjects perform their daily activities and give future research directions to develop tools to support early AD diagnosis through analysis of eye movements.

Customer engagement is one of the most debated topics in marketing literature. The great interest of the scientific community resulted in a large amount of research on this topic making it difficult for scholars to understand how to really contribute to advance the research. Based on these considerations, this chapter aims to provide an overview of the research findings and trends of previous studies to guide the researcher to the most influential works, results, and issues that need more insights. In particular, this chapter offers a literature review on customer engagement and retail customer engagement using bibliometric analysis and scientific mapping study. Results show the most productive authors, most cited publications, most frequent words, and clusters of related words. The analysis provides a description of the state of the art of retail customer engagement and suggests future research directions.

This chapter seeks to present the dependence of throughput on signal to noise ratio (SNR) in IEEE802.11 WLAN systems. High throughput and low delays are presented as the requirements for indicating good performance of WLAN systems. The multiple communication data rates specified by the physical layer of IEEE802.11 WLANs which vary depending on the SNR observed is shown to appreciably influence the throughput experienced by the users. Cross-layer modelling principles which simplifies the process of estimating the dependence of throughput on SNR is presented. Recent research findings which apply cross-layer modelling principles to model the dependence of throughput on SNR only is presented along with future research directions.

One of the goals of science education is to ensure that the discipline of science is accessible to all individuals. By many organizations this has been termed “Science for All,” and those who promote this idea also advocate the connection to science literacy. Teaching science in the online environment has been one way to offer science content to many different individuals, who do not necessarily need to be in the same location. Discourse in the science classroom is framed under situated cognition theory, whereby interactions between individuals are part of the normal culture of the classroom. For science knowledge to be adequately constructed by a student these interactions must be meaningful ones. This is especially important in an online science course where typically learning occurs through interactions between the students and the instructor, the students with one another, and within the individual themselves. As part of these online interactions, good reflective practice includes the different forms of feedback and the quality of this feedback. However, even with quality reflective interactions, there are barriers to science concept construction in an online environment. These barriers are discussed, and future research directions are suggested based on this review.

AbstractGalling phenomena in metal forming not only affect the quality of the engineered surfaces but also the success or failure of the manufacturing operation itself. This paper reviews the different galling conditions in sheet and bulk metal forming processes along with their evolution and the effects of temperature on galling. A group of anti-galling methods employed to prevent galling defects are also presented in detail. The techniques for quantitatively measuring galling are introduced, and the related prediction models, including friction, wear, and galling growth models, are presented to better understand the underlying phenomena. Galling phenomena in other processes similar to those occurring in metal forming are also examined to suggest different ways of further studying galling in metal forming. Finally, future research directions for the study of galling in metal forming are suggested.

In this paper, the sleep phenomenon is considered in relation to critical care soundscapes with the intention to inform hospital management, medical device producers and policy makers regarding the complexity of the issue and possible modes of design interventions. We propose a comprehensive strategy based on soundscape design approach that facilitates a systematic way of tackling the auditory quality of critical care settings in favor of better patient sleep experience. Future research directions are presented to tackle the knowledge deficits in designing for critical care soundscapes that cater for patient sleep. The need for scientifically-informed design interventions for improving patient sleep experience in critical care is highlighted. The value of the soundscape design approach for resolving other sound-induced problems in critical care and how the approach allows for patient-centred innovation that is beyond the immediate sound issue are further discussed.
