Abstract
Purpose
The purpose of this paper is to deal with the self-heating of semiconductor nano-devices.
Design/methodology/approach
Transport in silicon semiconductor devices can be described using the Drift-Diffusion model, and Direct Simulation Monte Carlo (MC) of the Boltzmann Transport Equation.
Findings
A new estimator of the heat generation rate to be used in MC simulations has been found.
Originality/value
The new estimator for the heat generation rate has better approximation properties due to reduced statistical fluctuations.

Abstract
Purpose
The purpose of this paper is to set up a consistent off‐equilibrium thermodynamic theory to deal with the self‐heating of electronic nano‐devices.
Design/methodology/approach
From the Bloch‐Boltzmann‐Peierls kinetic equations for the coupled system formed by electrons and phonons, an extended hydrodynamic model (HM) has been obtained on the basis of the maximum entropy principle. An electrothermal Monte Carlo (ETMC) simulator has been developed to check the above thermodynamic model.
Findings
A 1D n+−n−n+ silicon diode has been simulated by using the extended HM and the ETMC simulator, confirming the general behaviour.
Research limitations/implications
The paper's analysis is limited to the 1D case. Future researches will also consider 2D realistic devices.
Originality/value
The non‐equilibrium character of electrons and phonons has been taken into account. In previous works, this methodology was used only for equilibrium phonons.

Abstract
Purpose
The purpose of this paper is to investigate the influence of contextual factors on the attribution of responsibility to female victims of an intimate partner violence (IPV) episode. The victim’s infidelity and the perpetrator’s alcohol abuse constituted the contextual factors in the investigation. The bystander’s age, gender, and attitude towards gender roles were predicted to influence the attribution of responsibility to an IPV victim, and their willingness to help.
Design/methodology/approach
An experimental study was conducted with 464 Italian participants with two independent conditions incorporated into a fictional scenario, measuring the different levels of the dependent variables under investigation. The participants were randomly assigned to different conditions provided their answers via an anonymous questionnaire.
Findings
The participants attributed more responsibility to the victim when they admitted infidelity, controlling for gender role norms and sexism. Attribution of responsibility, male gender, and attitudes towards the male gender role were significantly associated with less willingness to help the victim.
Practical implications
The results point to the importance of increasing the bystander’s role in preventing IPV by addressing gender role norms and their impact on the justification of violence.
Originality/value
The study complements the existing literature by providing new evidence of the barriers that prevent the bystander’s intervention in IPV episodes. A clearer understanding of these barriers will help to develop strategies that aim to prevent violence in the future.

Abstract
Are radically novel practices more likely to attract recognition when the evaluating audience is composed of external evaluators? Our baseline argument asserts that radical novelty is more likely to be positively evaluated by an external audience and that peripheral (rather than core) producers have higher incentives to adopt novel practices that depart from tradition. Yet, because peripheral producers often lack the necessary support and legitimacy to promote novelty, audiences play a critical role in recognizing their innovative efforts. How can peripheral producers mitigate the challenges associated with novelty recognition? To answer this question, we explore how peripheral producers’ collaboration with acclaimed consultants affects the process of external audience recognition in the context of the Italian wine field from 1997 to 2006. Our findings suggest that radical novelty is positively received by an external audience composed of critics, although we do not find a significant difference between core and peripheral producers. However, external audiences are more open to recognizing peripheral producers’ use of novel practices when they collaborate with well-connected consultants. We find that the use of central consultants produces a “boosting” effect that accentuates the differences between evaluations of peripheral producers who embrace novelty and evaluations of those that follow the tradition. Our study thus advances theory by providing empirical evidence of the value of considering third-party actors such as consultants, who sit at the nexus between the agency required for innovation and external audiences’ recognition of novelty, when studying novelty evaluation and recognition.
