Abstract

This paper details the development of a rapid tooling manufacturing route for the gravity and high‐pressure die‐casting industries, resulting from an EPSRC funded collaborative research project between the Universities of Warwick, Loughborough and DeMontfort, with industrial support from, amongst others, MG Rover, TRW Automotive, Sulzer Metco UK Ltd and Kemlows Diecasting Products Ltd. The developed process offers the rapid generation of mould tools from laser‐cut laminated sheets of H13 steel, bolted or brazed together and finish machined. The paper discusses the down‐selection of materials, bonding methods and machining methods, the effect of conformal cooling channels on process efficiency, and the evaluation of a number of test tools developed for the industrial partners. The paper also demonstrates the cost and time advantages (up to 50 and 54 per cent, respectively) of the tooling route compared to traditional fabrication methods.

Abstract

Developing student engagement in the online classroom and within co-curricular digital spaces is about relationship building more than technology or class structure. Where the learning management system is used effectively, online learning can equal or exceed the engagement levels of face-to-face classrooms particularly with Millennial and Generation Z students. Beyond technology is the need to create a higher value aspect of learning by developing models closely aligned with “communities of practice” (Wenger, 2000) or “communities of inquiry” (Garrison, 2007). This chapter will examine how to engage Millennial and Generation Z traditional undergraduate students through distance learning approaches in ways that support student learning and development.

Abstract

Purpose

The purpose of this paper is to explore the significance of psychological resiliency for evacuated disaster survivors and the possible implementation of a concept known as homes away from home aimed at fostering such resiliency.

Design/methodology/approach

To address the topic of resiliency in evacuated disaster survivors, first an evacuation scenario is explored. The scenario is followed by a discussion of disaster psychology, resiliency, and a development of the homes away from home concept.

Findings

The development of an evacuated disaster survivor's individual and community resiliency shows promise as an effective means of mitigating the psychological damage of a disaster or terrorist attack. The implementation of the homes away from home concept, designed to foster such resiliency in emergency shelters could be effective.

Practical implications

Incorporating accommodations for the development of individual and community psychological resiliency in emergency shelters in emergency operations plans could be more tangible with the homes concept. A shift in sheltering practices is necessary to meet not only the basic needs of survivors but higher needs as well.

Originality/value

The homes away from home concept is new as there are few if any models for emergency shelters that specifically offer direction to local jurisdictions to develop individual and community resiliency.

Abstract

Purpose – In this chapter, I examine the ways that various trauma carriers, including social movements, self-identified survivors, professional organizations, and advocates make public claims about trauma and the PTSD diagnosis as they work to define moral and political issues.

Methodology/approach – Employing the method of social pattern analysis, I analyze a variety of narrative data pertaining to issues such as child sexual abuse, war, slavery, and genocide.

Findings – Trauma carriers engage in significant social memory work and collective identity work, define social problems, and practice social activism as they address the causes and consequences of psychological suffering. Within the context of modern diagnostic psychiatry, the PTSD diagnosis stands out as a unique narrative of social illness. The PTSD diagnosis is a powerful cultural script that various individuals and interest groups use to interpret mental health symptoms while attributing psychological consequences to social causes as opposed to problems rooted in the individual's psyche (as with psychoanalysis) or neurophysiology (as with modern diagnostic psychiatry). By implication, the social world must be “cured” for the individual to be healthy.

Originality/value of paper – I detail the unique sociocognitive implications of the PTSD diagnosis, highlighting its impact on our collective understanding of particular traumatic experiences and the shared nature of posttraumatic affect. I show the relevance of social memory studies, the more broadly conceived sociology of culture and cognition – especially as it pertains to collective identity and classification norms, the sociology of health-focused social movements, and the analysis of social problems claims-making to an emerging sociology of diagnosis.

Abstract

Purpose

The purpose of this study is to ascertain perspectives from pre-service and in-service elementary teachers about challenges they face when teaching social studies, and how their participation in a content-based professional development opportunity can support their preparedness for social studies instruction. Five speakers who were experts in topics such as Native American history, historical preservation, women's history and the Constitution were featured at this workshop.

Design/methodology/approach

Case study methodology with both descriptive and explanatory data collection and analysis methods, which were inclusive of surveys and focus group sessions, was implemented. The National Council for the Social Studies (2017) Powerful and Authentic Social Studies framework was applied in order to examine whether elementary in-service and pre-service teachers participation in this content-focused professional development impacted their preparedness to teach social studies.

Findings

Major findings show that content-specific professional development can support pre-service and in-service elementary teachers' preparation to teach social studies through analysis of historical topics and contemporary issues, as well as mitigate challenges with regard to limited time dedicated to social studies instruction.

Originality/value

In light of the Senate's debate on passing the Educating for Democracy Act concerning funding for civics and history education, the originality of this study highlights the continued need for scholarship on how partnerships between colleges of education, school districts and local educational agencies to provide content-focused professional development can support elementary teachers' ambitious social studies instruction, which can foster greater understandings of historical content and civic participation in democratic society.

Abstract

Purpose

The main aim of this study is to generate curved-form cut on the edge of an adaptive layer. The resulting surface would have much less geometry deviation error and closely fit its computer aided design (CAD) model boundary.

Design/methodology/approach

This method is inspired by the manual peeling of an apple in which a knife's orientation and movement are continuously changed and adjusted to cut each slice with minimum waste. In this method, topology and geometry information are extracted from the previously generated adaptive layers. Then, the thickness of an adaptive layer and the bottom and top contours of the adjacent layers are fed into the proposed algorithm in the form of the contour and normal vector to create curved-form sloping surfaces. Following curved-form adaptive slicing, a customized machine path compatible with a five-axis abrasive waterjet (AWJ) machine will be generated for any user-defined sheet thicknesses.

Findings

The implemented system yields curved-form adaptive slices for a variety of models with diverse types of surfaces (e.g. flat, convex, and concave), different slicing direction, and different number of sheets with different thicknesses. The decrease in layer thickness and increase of the number of the sloped cuts can make the prototype as close as needed to the CAD model.

Research limitations/implications

The algorithm is designed for use with five-axis AWJ cutting of any kind of geometrical complex surfaces. Future research would deal with the nesting problem of the layers being spread on the predefined sheet as the input to the five-axis AWJ cutter machine to minimize the cutting waste.

Practical implications

The algorithm generates adaptive layers with concave or convex curved-form surfaces that conform closely to the surface of original CAD model. This will pave the way for the accurate fabrication of metallic functional parts and tooling that are made by the attachment of one layer to another. Validation of the output has been tested only as the simulation model. The next step is the customization of the output for the physical tests on a variety of five-axis machines.

Originality/value

This paper proposes a new close to CAD design sloped-edge adaptive slicing algorithm applicable to a variety of five-axis processes that allow variable thickness layering and slicing in different orientations (e.g. AWJ, laser, or plasma cutting). Slices can later be bonded to build fully solid prototypes.

Abstract

Purpose

The aim of this study is to demonstrate the benefit of design flexibility afforded by the Arcam free‐form fabrication process in the direct manufacture of injection mould inserts with complex cooling channel configurations and the process efficiency and quality gains achieved through using such inserts.

Design/methodology/approach

The manufacturing process of a flood cooled injection mould insert using the Arcam EBM S12 layered manufacturing process is presented. The insert is then evaluated against two other inserts (one un‐cooled and one traditionally baffle cooled (BC)) in the manufacture of test components, with the temperature of the insert and components recorded. The process conditions were adjusted (reduced cooling time) to increase the core and component temperatures to identify the operational limits of the inserts. Thermal imaging was employed to visualize the thermal distribution within the BC and flood cooled (FC) inserts.

Findings

The cooling efficiency of the FC insert was found to be significantly higher than that of the other two inserts, and the homogeneity of the heat distribution of the FC insert was more even than the BC insert. It was possible to manufacture non‐deformed components using the FC insert with zero cooling time (ejection immediately after removal of holding pressure), this was not possible with the BC insert.

Research limitations/implications

Provides a basis for the development of more efficient and thermally homogeneous inserts through the Arcam EBM process.

Practical implications

Provides a technology/process for the manufacture of highly efficient core inserts for injection moulding, offering the industry a competitive advantage through the potential for time and cost savings and higher quality components.

Originality/value

This is the first direct comparison of an Arcam EBM manufactured insert with complex cooling geometries against traditionally cooled inserts, particularly novel is the thermal imaging analysis of the cooling efficiency and distribution.

Abstract

Purpose

The paper examines terrorism in its relationship to the workplace. The purpose of this paper is to review research findings and propose a model of the effects of terrorism on work-related outcomes.

Design/methodology/approach

A literature review was undertaken mainly using academic sources.

Findings

Potential or actual terrorist attacks create a significant fear level for the individual, causing negative work attitudes. In turn, negative attitudes lead to undesirable work behaviors.

Research limitations/implications

Relatively little research has been conducted to determine how organizations may be affected by terrorism via the reciprocal relationship between employee and organizational well-being.

Originality/value

This paper explores important yet still under-researched areas of management and organizational interventions to mitigate the deleterious effects of workplace terrorism.

Abstract

Purpose

The purpose of this paper is twofold: first, to argue that substance use is a real risk for people who experience disaster, and especially so for socially vulnerable populations; second, to incorporate questions that help measure substance use during the disaster life cycle in pre-existing data sets.

Design/methodology/approach

The authors provide a critical review and discussion of what is missing from current drug use data sets, and how they could incorporate collection techniques for disaster stricken populations. The manuscript is not based on research but helps develop and test hypotheses. The authors are more discursive, and review philosophical discussions and comparative studies of other pre-existing data sets that collect substance use information.

Findings

Although it would take some effort to change these pre-existing national surveys, it could be done, which would allow researchers to collect much more extensive and informative data with regard to substance use during the disaster life cycle.

Research limitations/implications

This manuscript is a commentary/discussion piece that proposes ideas for improved data collection. Ideally, the authors would be able to test these updated surveys.

Practical implications

Improved data collection methods, and improved emergency response and recovery.

Social implications

Having the ability to collect these data will ultimately make communities more resilient.

Originality/value

The authors argue that the overlap of crime and disaster, in which substance use during the disaster life cycle falls, is an extremely understudied area. As the field of disaster studies continues to grow, the methodological and theoretical challenges of studying crime and disaster have prevented this sub-field from advancing. The authors wish to advance the discipline by pushing toward improved data collection during substance use during the disaster life cycle.
