Abstract
Training is a critical factor in enabling users to make effective use of their computers. A variety of training methods have been proposed in the literature. These training methods will be considered within the framework of procedural and conceptual training, with special reference to their application in the training of novice end users in the use of applications software. The impact of learning styles and other user characteristics on the selection of training methods for use in this area is discussed. Finally, a current research programme to explore the effectiveness of training methods for novice end users is briefly described.

Abstract
It has been suggested that conceptual models can be used to enhance the training of novice end‐users. This paper discusses the part played by metaphor in conceptual models, provides examples of end‐user training incorporating metaphors, and contends that metaphors facilitate the development of accurate mental models. The more specific issue of the role of conceptual models, and by implication metaphor, in the training of end‐users remains to be investigated, and a research agenda for this purpose is outlined.

Abstract
The use of energy balance and simplified hydrodynamic models for simulating GaAs devices is investigated. The simplified hydrodynamic model predicts velocity spikes that are not present in more detailed Monte Carlo simulation results. These velocity spikes are associated with overestimation of thermal diffusion. The simplified hydrodynamic model can predict terminal currents that are significantly lower than those predicted by the energy balance model. The differences between the models are significantly greater than those observed previously for silicon devices. The main conclusion of this study is that the energy balance model is preferable to the simplified hydrodynamic model as the basis for GaAs device simulation, but the energy balance model still needs refinement to improve the agreement with more general simulation and experimental results.

Abstract
Self‐consistent electrothermal simulation of modern semiconductor devices is required for the accurate and efficient design and optimization of many semiconductor devices. The need to perform this type analysis in order to predict the behavior of power devices was realized many years ago. It is now clear that nonisothermal analysis can be very important for VLSI devices as well.

Abstract
There are many methods by which the state of dispersion of pigments may be studied, either in the liquid paint or in the dried film. They range from essentially practical methods useful for production control to sophisticated laboratory techniques capable of providing quantitative data on the number, size, and type of particles present in a dispersion.

Abstract
Purpose
A qualitative approach based on grounded theory was utilized, with data collected through 26 semi-structured interviews with social entrepreneurs. Alas’s Triangular Model provided the framework for data analysis and interpretation.
Design/methodology/approach
This study explores how Hong Kong social enterprises approached crisis and change management during the COVID-19 pandemic, examining their resilience-building strategies.
Findings
The pandemic triggered an existential crisis for many social enterprises, causing severe revenue losses. However, strong leadership and cultures based on social mission enabled resilience. Enterprises demonstrated agility by rapidly transitioning operations online and establishing partnerships. Technology adaptation and social innovation were pivotal to sustaining impact.
Research limitations/implications
As the sample comprises enterprises that survived the pandemic, insights into failed enterprises are lacking. Comparative analysis could illuminate differences in crisis response between successful and unsuccessful cases.
Practical implications
The study’s practical implications suggest that social enterprises should focus on developing flexible crisis management plans, cultivating purposeful leadership, embracing digital transformation, strengthening collaborative networks and prioritizing organizational learning to effectively navigate crises while staying true to their social missions.
Social implications
Findings demonstrate how shared values and cultures grounded in purpose can anchor organizations amidst upheaval, fostering resilience. This underscores the role of social enterprises in modeling responsiveness to societal needs.
Originality/value
While research has examined social enterprises’ vulnerability in crises, investigation into their crisis management practices is limited. This study enriches understanding of how social enterprises effectively navigate turbulence.

Abstract
The changes generated by information and telecommunication technologies in the organization of work activities may influence the way that modern cities will change in both the short and long term. The radical changes predicted in the first utopian scenarios have not taken place yet, but there is evidence of slow changes that are reshaping work and urban structures. This article analyses this evidence, in the light of the utopian and dystopian views proposed by many authors, with the aim of outlining scenarios for the future of work activities and urban structures.

Abstract
An improved velocity‐space carrier transport model is presented, based on a direct solution of the Boltzmann Transport Equation. This model attempts to achieve the computational efficiency required for device simulation, while still solving for the distribution function itself. This preserves critical fine structure effects due a non‐ideal band structure and forward scattering mechanisms. The model includes a numerically efficient representation of three dimensional k‐space formulated around a 1D velocity‐space variable, and the particle energy. The number of empirical parameters in the model is reduced to a single constant per scattering mechanism. A physically intuitive solution algorithm is developed which repeatedly shifts and shapes the estimate of the distribution until convergence. Results are presented for the steady‐state homogeneous case in silicon and GaAs, which are of comparable computational cost as drift‐diffusion simulations.

Abstract
Time and frequency domain complementary numerical models of microwave non‐linear circuits using two‐terminal active semiconductor devices are presented. Their main feature is the use of numerical one‐dimensional macroscopic physical models as semiconductor device models. Their respective capability is illustrated by some results of a study devoted to the optimization of millimeter‐wave avalanche diode frequency multipliers.

Abstract
Purpose
In the last two decades sports studies and sports management journals have called for there to be research in sports management that explores sports links to mainstream management analyses. The purpose of this paper is to argue that in many ways the sports sector is dominated by small and medium sized enterprises (SMEs), which have a different dynamic to larger entities and therefore should be analysed accordingly. This paper applies an SME perspective on English professional football clubs.
Design/methodology/approach
This paper, drawn from 22 semi‐structured interviews with key individuals in the English professional football (soccer) industry, employs an interpretivist approach of semi‐structured interviews of key personnel to provide an account of the business practices prevalent in the English football industry.
Findings
The findings are as follows: that the sports industry can be regarded as one that is largely constituted of elements that are ascribed with characteristics associated with SMEs called archetypal SMEs, either in entity size, turnover or mentality; that much analysis of the administration and management of the sports industry fails to assess the sector through the prism of SME “modelling”; there are areas of engagement with SME literature that could be useful to the analysis of the management of the sports industry.
Originality/value
This paper does what few other papers have achieved by outlining that the sports industry can be effectively examined by applying “SME perspectives” to help explain what might appear to be their idiosyncratic characteristics.
