Abstract
This chapter aims to seek insight into engagement in context, conceived through Productive Disciplinary Engagement (PDE), which can be perceived as a condition for sustained disciplinary and interdisciplinary interest and motivation. Despite ongoing trends in the design and implementation of enriched learning environments that are expected to boost effective use of material and digital tools along with new sources of information, the empirical research on their motivational and emotional consequences is still in its infancy. These environments challenge, cognitively as well as motivationally, emotionally, and socially, both students and teachers alike. Keeping in mind the challenging times for future learning and work-life, engagement and motivation are discussed with a focus on science disciplines. In these fields, there is a strong call for proficient skills in collaborative team learning, problem-solving, and collective knowledge creation in anticipation of an uncertain, challenging future. Knowledge-intensive work and knowledge demands are escalating along with fast technological development, and simultaneously tasks that demand new, not yet even existing and partly unpredicted knowledge and expertise are increasing. In addition, knowledge and expertise are progressively more distributed, with new knowledge, products and innovations being created in collaboration that crosses disciplinary borders. In this chapter, three case illustrations in different science fields and learning contexts provide empirical evidence for the discussion on the learned lessons from these illustrated studies designed to support PDE, and the potential significance of PDE for productive collaboration, sustained disciplinary interest, and motivation given later development of adaptive expertise.

Abstract
This article describes a study that has been made on the automation of deburring in a foundry. Circular castings weighing up to 20kg are deburred before delivery in order to make them fit into machining cells. The maximum production rate of the cylindrical castings on the foundry line is one casting every ten seconds. However, the castings are produced in small batches, typically ranging from 100 to 1,000. After casting and integrated sand blasting and cooling chambers, the castings are transferred further on a conveyor belt. Deburring is today done manually by lifting and pressing against different grinding and deburring machines. Bins and forklifts are used in transport and storage of castings, from production line to deburring and shipment.

Abstract
Purpose
The purpose of this paper is to design an integrated localization system for mobile robots in underground environments for exploring and rescuing tasks after incidents and detection of hazard gas in tunnels before ingress.
Design/methodology/approach
An integrated localization system mainly based on a strap‐down inertial measurement unit and a digital compass is designed for exploring and rescuing task in coal mines and tunnels. After a system model was founded, a filtering algorithm combining a wavelet‐based pre‐filter with unscented Kalman filters was developed for reckoning tracks of robots and localizing it.
Findings
Based on this research, an integrated localization system for robots in underground environments can be developed to explore some regions and rescue people. Although errors of localization exist, performance of the integrated system should be improved if some sensors and landmarks or maps of tunnels are introduced.
Originality/value
What is proposed in this paper is an integrated localization system used in underground environments. In this research, property of environments has been taken into account as an important disturbance when filtering thresholds were set.

Abstract
Prior learning and prior knowledge are among the most dependable and consistent factors in predicting students’ success (Richardson et al., 2012). Although for UK Higher Education, the traditional A-level (advanced level qualification) remains the principal qualification students use to gain entry to University, there has been a small but significant rise in alternative qualifications, such as the International Baccalaureate (IB) and vocational qualifications such as that from the Business and Technology Education Council (BTEC). The multidisciplinary nature of Psychology means students enter the degree program with a range of qualifications in differing topic areas. The current case study aimed to assess if science qualifications aided student success in the University of Liverpool’s Psychology course. Ordinal regression and correlations were used to examine the impact of prior qualifications on three first-year cohort module scores (Psychobiology, Social psychology, and Research Methods) and the overall degree mark across three cohorts of Psychology students (n = 1,072). University entry grades showed a significant overall and subject specific effect of scientific prior knowledge. However, the effects of previous qualifications were not cumulative and did not persist beyond the first year of study. These findings were strongest for Chemistry in the Psychobiology module suggesting that scientific literacy – the understanding of scientific concepts, phenomena, and processes, as well as an individual’s ability to apply such knowledge to new or non-scientific situations (Schleicher, 2019) – rather than domain-specific knowledge is driving such increase in grades. A negative relationship was seen for those holding BTEC qualifications, suggesting that vocational qualifications, specifically for this Psychology program, were of less use than academic ones, even if topic areas were similar – a finding which may also apply to other academic based courses, and warrants further study. Although the advantage of prior qualifications diminishes across the course of study, this small but distinct advantage suggests that making a science qualification a requirement for a place on a Psychology degree course would be a beneficial step for admissions tutors to consider.

Abstract
Promoting mental health and meeting the needs of the large numbers of the general public with problems of anxiety and depression is a big challenge. Particular difficulties are the low capacity of the therapy services and the reluctance of the general public to seek help. The aim of this study was to compare the attendance, effectiveness and characteristics of participants self‐referring to six different psycho‐educational workshops, each using non‐diagnostic titles: self‐confidence; stress; sleep; relationships; happiness; and anger. The series of day‐long workshops ran for one year and were offered to members of the general public in south east London. Over a quarter had not previously sought help from their GP. The take‐up rates for the self‐confidence, sleep and anger workshops were highest and one month after attending these workshops, participants reported significantly lower depression and distress. It was concluded that a self‐referral route to some day‐long workshops can attract quite large numbers of the general public and provide access to effective psychological treatment. These workshops can be used as an effective way of promoting mental health and improving the provision of evidence‐based mental health treatment in the community, possibly within the Improving Access to Psychological Treatments (IAPT) programme in the UK.

Abstract
Purpose
Reviews the benefits and potential application of tactile sensors for use with robots.
Design/methodology/approach
Includes the most recent advances in both the design/manufacturing of various tactile sensors and their applications in different industries. Although these types of sensors have been adopted in a considerable number of areas, the applications such as, medical, agricultural/livestock and food, grippers/manipulators design, prosthetic, and environmental studies have gained more popularity and are presented in this paper.
Findings
Robots can perform very useful and repetitive tasks in controlled environments. However, when the robots are required to handle the unstructured and changing environments, there is a need for more elaborate means to improve their performance. In this scenario, tactile sensors can play a major role. In the unstructured environments, the robots must be able to grasp objects (or tissues, in the case of medical robots) and move objects from one location to another.
Originality/value
In this work, the emphasis was on the most interesting and fast developing areas of the tactile sensors applications, including, medical, agriculture and food, grippers and manipulators design, prosthetic, and environmental studies.

Abstract
This paper highlights the social context of common mental disorders in primary care and the paucity of evidence relating to effective social interventions. It introduces the ABC‐E Model of Emotion, which combines social interventions with psychological therapy, and discusses how the implementation of the new role of graduate primary care mental health worker (GPCMHW) provides an opportunity for holistic practice in helping individuals experiencing mild to moderate mental health difficulties in primary care. It provides a case example of the implementation of the ABC‐E model and makes recommendations for further research including the evaluation of the model and GPCMHW training programmes.

Abstract
Examines over the period from 1975 to 2000 the attitudes of Finnish consumers toward the products and associated marketing practices of Japan in comparison to those the United States. Concludes that, although there are significant differences between the attitudes of consumers toward the products and practices of the Japan and the U.S., the ratings of Japan and the U.S. typically improved over the period in distinctive ways. Raises some strategic implications for Japanese and U.S. firms who market their products in the European Union.
