Abstract

The ability to simulate the effects of process technology on final product circuits has become virtually indispensable in modern VLSI production. It is especially significant as a toot for controlling parametric yield by appropriate design centering and in determining the sensitivity of the electrical parameters to process control tolerances. The system demands the combined use of process simulation device simulation and circuit simulation all three of which rely heavily on computationally intensive numerical solution of partial differential equations. The severe computational overhead involved in ‘technology simulation TCAD)’ means it is generally expensive and limits the scope of statistical design centering and optimisation, which depend on a large number of simulations. A compromise solution is often resorted to by limiting simulation to one or two spatial dimensions, replacing numerical simulation by analytical approximations as implemented in the statistical process simulator: FABRICS 11, or combining numerical and analytical models as in the process/device simulator PRIDE.) This paper addresses the problem of simpler, higher efficiency TCAD evaluation by restricting the domain of the simulation and approximating the process/device characteristic relationship by a set of simple, computationally efficient empirical equations. These equations offer a high speed solution at the expense of decreasing accuracy away from the nominal process centre. Referred to as a ‘response surface model’, it is generated using the results of a small number of statistically designed TCAD simulations. As the process sample is centred around the nominal design parameters, the model can be used to statistically analyze the effects of process perturbations.

Abstract

Purpose

The purpose of the present work is to develop a methodology for making physical models of catchment areas and terrains by rapid prototyping (RP) using geographic information systems (GIS) data. It is also intended to reduce data loss by minimising intermediate data translations.

Design/methodology/approach

The GIS data of a catchment area or a terrain were directly translated to an stereo lithography (STL) file. The STL surface was then manipulated in Magics‐RP to obtain a solid STL part, which can then be downloaded to a RP machine to obtain a physical model or representation of a terrain or catchtment area.

Findings

Intricate geometries of landforms were created with ease and great accuracy in RP machines. Terrain models were created in less time and lower cost than with conventional methods.

Research limitations/implications

DEM ASCII XYZ (digital elevation model) data were used to input the required GIS data of specific terrains. Software can be developed for translation and manipulation of DEM, STL and other relevant file formats. This will eliminate any data loss associated with intermediate file transfer.

Practical implications

Terrain models were created with ease and great accuracy in RP machines. It takes less time and can be done more cost‐effectively. Terrain models have intricate geometries and for complex models, it may take months to make using conventional methods.

Originality/value

STL surfaces were obtained directly from GIS data for terrain modeling. This work fulfils the need of terrain modeling for catchment management, town‐planning, road‐transport planning, architecture, military applications, geological education, etc.

Abstract

Since the 1990s, Charlize Theron has appeared in films from a wide range of genres but has seen significant financial success from starring in action films, such as Mad Max: Fury Road (2015) and Atomic Blonde (2017). However, unlike some female action leads, she has not solely been defined or pigeonholed by these roles but has been able to transition between action roles and more ‘respectable’ dramatic roles, as well as the other conventions of female celebrity, such as being the face of advertising campaigns for perfume brands.

Theron has notably received several physical injuries during filming, such as breaking her teeth practising fight choreography during the production of Atomic Blonde. These injuries have frequently been added as part of the publicity campaign for the films and Theron's star image overall as signs of ‘authenticity’, leading these action films a sense of increased legitimacy. Tasker states that a female action star's ‘[public] formulation is indicative of the uncertainties generated by her image’ (1993, p. 14). Media attention is divided between focusing on Theron's physicality, both in the sense of the traditional Hollywood gaze and in terms of Theron's molding of her marketable image. Theron has managed to succeed as both a mainstream star and an action heroine. This has enabled Theron to transition between genres and franchises such as The Fate of The Furious (2017), and an Oscar-nominated dramatic role in the biopic Bombshell (2019).

This chapter will unpack the public persona of Charlize Theron as an action film star, exploring both the filmic texts and the presentation of Theron's often complicated and contradictory image in the media.

Abstract

Purpose

In this paper the authors share, and reflect critically on, the experience of using digital storytelling (DS) methods in a South African township. We interrogate the innovations prompted as we operationalized DS in a context that has historically prized collectivist values and that experiences chronic resource constraints.

Design/methodology/approach

The authors ask: How can DS be optimally used to understand youth resilience in a collectivist, developing context? The authors worked with 18 older adolescents (aged 18–24) during two day-long events. The authors provide detailed descriptions of the method used, and offer reflections focusing on narrative, visuals and technology-mediation.

Findings

This study concludes by sharing four key lessons learned during the project. First, revisit the definition of “story” for your context, participant group and time. Second, a slower process yields more meaningful product. Third, facilitator competence matters. Finally, advance and deeper thinking about the ways in which technology will be used leads to richer research outcomes.

Originality/value

The paper reflects on the interplay between the transactional nature of contemporary digitally-mediated methods in a low-resource setting and with a seldom-heard population, and it's relationship with the ancient local traditions of story-making and audiencing.

Abstract

This chapter focuses on spy action as a way to answer the question: where can we find queer female action heroes? The chapter will identify three films – D.E.B.S. (Advocate, 2005), Atomic Blonde (David Leitch, 2017) and The Spy Who Dumped Me (Susanna Fogel, 2018) – worth attention to highlight the potential and problems of the queer female hero in spy action. This chapter examines how each of these spy action films contributes to the ongoing yet uneven development of the female hero as a queer figure in post-millennial action cinema. The chapter will consider to what extent these queer female-led action films may pose a challenge to some of the dominant standards and conventions associated with the action hero, gender roles and the representation of sexuality, but also reinforce others. Some comparisons will be made to James Bond in recognition that the Bond franchise has played an important role in the spy action genre.

Abstract

Purpose

The purpose of this paper is to examine the potential benefits as well as some of the practical barriers to the implementation of a collective impact initiative in law enforcement and public health (LEPH) in Tasmania, Australia.

Design/methodology/approach

The paper is based on a review of programs, agencies and initiatives that are at the intersection of LEPH in Tasmania, through an analysis of the findings in evaluation reports, and the views of practitioners identified at a workshop on LEPH held at a national AOD conference and facilitated by the authors.

Findings

The strengths of collective impact initiatives, particularly in LEPH, are presented and some weaknesses identified. Some major obstacles to the consolidation of LEPH initiatives include siloed ways of working and budgets, lack of leadership and political will. Some progress has been made in addressing these weaknesses, although addressing complex social problems by moving beyond inter-agency collaboration toward an integrated model of service provision remains challenging.

Practical implications

The authors argue that there are practical benefits to the adoption of a collective impact model to address problems in Tasmania that lie at the nexus between LEPH. In reviewing existing collaborations, the authors demonstrate the value of a structural mapping process to identify ways forward for government and non-government agencies that are inclined to go further in merging the two disciplinary areas. The authors offer some suggestions with respect to identifying the preconditions for a collective impact model and how to build on these to initiate action.

Originality/value

A significant proportion of the literature on LEPH remains at a conceptual and theoretical level. This contribution highlights some practical issues while looking at existing examples of collaboration across LEPH at a state level in Australia, and starts mapping a way forward for constructing more integrative LEPH initiatives.

Abstract

Purpose

Over the last few decades, consumers’ concerns for healthier lifestyles and the environment have become the driving forces for forming food-buying intentions. The purpose of this paper is to investigate the impact of product attributes regarding nutrition and health benefits of products, the environmental impact of production and social responsibility of producers on consumers’ food and wine choices.

Design/methodology/approach

The empirical analysis is based on an online survey conducted in the USA, the UK and Germany, and incorporates a discrete choice experiment with visual shelf simulations.

Findings

Price and nutrition information are much more influential on consumers’ food choices than information about social responsibility of producers or the ecological impact of production. Product attributes emphasizing the ecological impact of production and social responsibility of food producers are specifically valued by consumers with high levels of environmental consciousness and by those concerned about goods production. Consumers who are health conscious regarding their lifestyle and diets derive high utility values from the nutritional information of the product.

Practical implications

The study contributes to an understanding of how to promote healthier food and wine choices and social and environmental responsibility of food and wine producers in various markets.

Originality/value

The study offers a comparison of product attributes concerning ecological, social, nutrition and health benefits of the product; as well the investigation of congruent interrelationships between the consumers’ values and related product attributes in three culturally distinct consumer groups.

Abstract

The PMI Risk Framework (PRF) is introduced as a guide to classifying and identifying risks which can be the source of post-merger integration (PMI) failure — commonly referred to as “culture clash.” To provide managers with actionably insight, PRF dissects PMI risk into specific relationship-oriented phenomena, critical to outcomes and which should be addressed during PMI. This framework is a conceptual and theory-grounded integration of numerous perspectives, such as organizational psychology, group dynamics, social networks, transformational change, and nonlinear dynamics. These concepts are unified and can be acted upon by integration managers. Literary resources for further exploration into the underlying aspects of the framework are provided. The PRF places emphasis on critical facets of PMI, particularly those which are relational in nature, pose an exceptionally high degree of risk, and are recurrent sources of PMI failure. The chapter delves into relationship-oriented points of failure that managers face when overseeing PMI by introducing a relationship-based, PMI risk framework. Managers are often not fully cognizant of these risks, thus fail to manage them judiciously. These risks do not naturally abide by common scholarly classifications and cross disciplinary boundaries; they do not go unrecognized by scholars, but until the introduction of PRF the risks have not been assimilated into a unifying framework. This chapter presents a model of PMI risk by differentiating and specifying numerous types of underlying human-relationship-oriented risks, rather than considering PMI cultural conflict as a monolithic construct.

Abstract

Purpose

This study (1) explores what programmes police services promote for autistic individuals on their websites and (2) describes how autistic individuals are constructed in the information about these programmes.

Design/methodology/approach

All 53 official police service websites in Ontario, Canada, were examined to determine which programmes were promoted for autistic individuals. Inductive qualitative content analysis was used to identify and describe how autism was constructed in the information about the programmes.

Findings

About 64.8% of police services in Ontario, Canada, promoted at least one programme to autistic individuals and their caregivers. These programmes included Vulnerable Person and Autism Registries, MedicAlert™ and Project Lifesaver™. Autistic individuals were described as vulnerable using medicalised and tragic narratives of autism.

Originality/value

Autistic individuals and caregivers have suggested several interventions to improve police-autistic individual encounters. Little is known about which interventions police services have adopted and which representations of autism are used to describe autistic individuals.
