The purpose of this paper is to solve non‐linear parametric thermal models defined in degenerated geometries, such as plate and shell geometries.
Abstract
Purpose
The purpose of this paper is to solve non‐linear parametric thermal models defined in degenerated geometries, such as plate and shell geometries.
Design/methodology/approach
The work presented in this paper is based in a combination of the proper generalized decomposition (PGD) that proceeds to a separated representation of the involved fields and advanced non‐linear solvers. A particular emphasis is put on the asymptotic numerical method.
Findings
The authors demonstrate that this approach is valid for computing the solution of challenging thermal models and parametric models.
Originality/value
This is the first time that PGD is combined with advanced non‐linear solvers in the context of non‐linear transient parametric thermal models.

Abstract
Purpose
The purpose of this paper is to focus on the Americanization of European advertising in the post‐war years as a phenomenon of cultural transfer and it aims to explore the interaction between the USA and Italian advertising traditions during the 1950s and the 1960s.
Design/methodology/approach
The analysis is in two parts. First, the role of those cross‐cultural mediators who contributed to changing marketing communication strategies of many Italian companies during the 1950s and the 1960s is studied. Second, the ways in which US advertising rules and patterns are combined with the local tradition in order to fit the Italian context of the post‐war years are looked at. The research is based on a study of the main USA and Italian marketing and advertising literature of the post‐war years, and on an analysis of press campaigns and TV commercials.
Findings
This research shows that during the 1950s and the 1960s, the conflict between the American approach and the Italian approach to advertising did not prevent interaction and negotiation. In the post‐war years, the USA know‐how and practices, are re‐interpreted through the process of transfer to Italy, creating original, and unexpected solutions.
Originality/value
Although some research has been conducted on the Italian advertising scene during the post‐World War II years, the few existing contributions did not focus on the interaction between the imported American model and the local traditions. This paper provides a good overview of the ways in which notions, methodologies, and strategies coming from the USA are implemented.

Abstract
Purpose
The research purpose is to investigate the mediating and moderating relationships between smartphone addiction and well-being (i.e. health-related quality of life).
Design/methodology/approach
A survey of 236 smartphone users was used to test the research model.
Findings
The structural equation modeling analysis results show that smartphone addiction negatively impacts well-being by draining a key personal resource, energy, thus creating strain. The adverse effect of smartphone addiction on users' well-being is found to be more intense when smartphones are used for hedonic purposes.
Research limitations/implications
Through the conservation of resources theory lens, this study increases our understanding of the role of strain in mediating the negative effect of smartphone addiction on well-being. This study also has practical implications. By exploring the mediating and moderating mechanisms underlying when and how smartphone addiction can be detrimental to well-being, interventions can be carried out to mitigate the adverse effects on well-being.
Originality/value
Past research has focused on the antecedents and consequences of smartphone addiction while ignoring the contextual factors of smartphone addiction effects as well as the intervening mechanism through which smartphone addiction impacts well-being. Through the lens of the conservation of resources theory, we close this gap in the literature by providing a better understanding of the mechanism by which smartphone addiction reduces well-being and identifying a relevant contextual factor (i.e. hedonic use) that can worsen the impact of smartphone addiction on well-being.

Abstract
Purpose
Enterprise social networks (ESN) that enable faster communications and knowledge sharing at work are an integral part of many workplaces. Although the affordances potency and actualization constructs identify work context as important, few studies to date have teased out how the interactions between ESN’s affordances, users’ goals and the work context drive affordances actualization.
Design/methodology/approach
This research is a case study of a technology multinational that made the ESN Chatter mandatory for all internal communications. We conducted a thematic analysis of 40 h of non-participatory observation, 15 in-depth interviews and eight informal conversations with employees.
Findings
There was considerable variation in how employees across different functional roles perceived affordances’ potencies, leading to differences in the nature and intensity of actualization: while sales and project managers embraced Chatter, technical support participants mostly resisted it; visibility was the central affordance for sales and human resources, but persistence was more important for project managers and association for technical support and billing. An organizational culture of accountability, urgency and efficiency interacted with Chatter’s affordances in a mutually reinforcing way, strengthening accountability and accelerating processes. Collaboration was enhanced but in a mostly coercive way. While sales participants' motivation was boosted, the mandated use of Chatter rendered tasks not inputted in Chatter invisible and created antagonism between departments.
Practical implications
Practitioners should not underestimate the influence of different work contexts and employees' goals when implementing an ESN. Since employees are concerned with managing their workload and how others perceive them, they may resist ESNs that they perceive as creating additional work and they may attempt to manage impressions at the expense of the work climate. Organizations looking to implement an ESN as their main communication tool would greatly benefit from establishing training programs and clear guidelines on positive communication practices across functional roles such as sales and technical support, and between peers.
Originality/value
Our study is one of the first to shed light on the role of the work context, i.e. functional role and organizational culture, in explaining the intensity and specificity of affordance actualization across an organization.
