Abstract
Purpose
Engagement is a critical metric to the effectiveness of online health messages. This paper explores how people engage in youth-generated prevention messages in social media.
Design/methodology/approach
The data sample consisted of engagement measures of 82 youth-generated messages hosted in a social media channel and a follow-up survey on content creators' motivation for promoting their messages and their dissemination strategies. A comparative analysis of engagement metrics along with qualitative analysis of the message types was performed.
Findings
Two types of messages were considered: stop messages and prevent messages. Our analyses found that people interacted with stop messages on social media more frequently than prevent messages. On analyzing the youth's motivation and promotion strategies, no significant difference was observed between stop message creators and prevent message creators.
Social implications
This work has implications for programs promoting prevention and health information in social media.
Originality/value
This is the first study in social media-based prevention programs the authors are aware of that differentiated between the strategies of youth-produced prevention messages.

Abstract
Purpose
This research study aims to develop regular cylindrical pore network models (RCPNMs) to calculate topology and geometry properties of explosively created fractures along with their resulting hydraulic permeability. The focus of the investigation is to define a method that generates a valid geometric and topologic representation from a computational modelling point of view for explosion-generated fractures in rocks. In particular, extraction of geometries from experimentally validated Eulerian smoothed particle hydrodynamics (ESPH) approach, to avoid restrictions for image-based computational methods.
Design/methodology/approach
Three-dimensional stabilized ESPH solution is required to model explosively created fracture networks, and the accuracy of developed ESPH is qualitatively and quantitatively examined against experimental observations for both peak detonation pressures and crack density estimations. SPH simulation domain is segmented to void and solid spaces using a graphical user interface, and the void space of blasted rocks is represented by a regular lattice of spherical pores connected by cylindrical throats. Results produced by the RCPNMs are compared to three pore network extraction algorithms. Thereby, once the accuracy of RCPNMs is confirmed, the absolute permeability of fracture networks is calculated.
Findings
The results obtained with RCPNMs method were compared with three pore network extraction algorithms and computational fluid dynamics method, achieving a more computational efficiency regarding to CPU cost and a better geometry and topology relationship identification, in all the cases studied. Furthermore, a reliable topology data that does not have image-based pore network limitations, and the effect of topological disorder on the computed absolute permeability is minor. However, further research is necessary to improve the interpretation of real pore systems for explosively created fracture networks.
Practical implications
Although only laboratory cylindrical rock specimens were tested in the computational examples, the developed approaches are applicable for field scale and complex pore network grids with arbitrary shapes.
Originality/value
It is often desirable to develop an integrated computational method for hydraulic conductivity of explosively created fracture networks which segmentation of fracture networks is not restricted to X-ray images, particularly when topologic and geometric modellings are the crucial parts. This research study provides insight to the reliable computational methods and pore network extraction algorithm selection processes, as well as defining a practical framework for generating reliable topological and geometrical data in a Eulerian SPH setting.

Abstract
Purpose
This paper aims to examine the interplay of emotions and consumption within intergenerational exchanges. It shows how emotions pervade the trajectories of grandmothers’ relational identities with their grandchildren through consumption practices.
Design/methodology/approach
This study analyses qualitative data gathered via 28 long interviews with French grandmothers and 27 semi-structured interviews with their grandchildren. This study draws on attachment theory to interpret the voices of both grandmothers and their grandchildren within these dyads.
Findings
This study uncovers distinct relational identities of grandmothers linked to emotions and the age of the grandchild, as embedded in consumption. It identifies the defining characteristics of the trajectory of social/relational identities and finds these to be linked to grandchildren’s ages.
Research limitations/implications
This study elicits the emotion profiles, which influence grandmothers’ patterns of consumption in their relationships with their grandchildren. It further uncovers distinct attachment styles (embedded in emotions) between grandmothers and grandchildren in the context of their consumption experiences. Finally, it provides evidence that emotions occur at the interpersonal level. This observation is an addition to existing literature in consumer research, which has often conceived of consumer emotions as being only a private matter and as an intrapersonal phenomenon.
Practical implications
The findings offer avenues for the development of strategies for intergenerational marketing, particularly promotion campaigns which link either the reinforcement or the suppression of emotion profiles in advertising messages with the consumption of products or services by different generations.
Social implications
This study suggests that public institutions might multiply opportunities for family and consumer experiences to combat specific societal issues related to elderly people’s isolation.
Originality/value
In contrast to earlier work, which has examined emotions within the ebb and flow of individual and multiple social identities, this study examines how emotions and consumption play out in social/relational identity trajectories.

Abstract
Purpose
The aim of this paper is to provide a brief overview of the evolution of a new e‐research paradigm and to outline key projects and developments in Europe, North America, Canada and Australia. The article also provides a detailed summary of the Dataset Acquisition, Accessibility and Annotation e‐Research Technology (DART) project.
Design/methodology/approach
A review of relevant government reports, documents and general literature was conducted.
Findings
Projects currently being conducted in Europe, the USA, Canada and Australia are part of an international movement that aims to use modern ICTs to enhance e‐research. The DART project is a significant part of this movement as it has adopted a “whole process” approach to e‐research, and provides a platform for the examination of the technical, legal and policy issues that arise in the new e‐research environment.
Originality/value
Provides an overview of current projects that concern the development of e‐research, with a particular focus on Australian research and the DART project.

Abstract
Despite the title of this bibliography, there was not a truly underground press in the United States during the 1960s and 1970s. The phrase is amisnomer, reputedly coined on the spur of the moment in 1966 by Thomas Forcade when asked to describe the newly established news service, Underground Press Syndicate, of which he was an active member. The papers mentioned in this bibliography, except for the publications of the Weather Underground, were not published by secretive, covert organizations. Freedom of the press and of expression is protected by the First Amendment to the Constitution, although often only symbolically as the experience of the undergrounds will show, and most of the publications that fall into the “underground” described herein maintained public offices, contracted with commercial printers, and often used the U.S. Postal Service to distribute their publications.

Abstract
In the past few years, many Australian organisations have either undergone or been planning a change from a hierarchical bureaucratic culture to a team‐based one. Much faith in the potential success of this kind of change appears to have been based on stories of transformations which worked well in overseas organisations, notably Japanese and American companies. One important issue for Australian organisational leaders was to come to terms with how the cultures of local and overseas companies were similar to or different from each other. For example, if the value systems of both local and overseas organisations tended to converge rather than diverge, the probability of developing a team‐based culture in Australian companies was relatively high. This paper critically examines stories of Australian organisations which are moving to a team‐based culture, from an adult communication management perspective. In particular, the paper aims to identify communication management variables which contribute to the successful implementation of teams in those organisations. Finally, conclusions and implications are drawn for maintaining high performance in team‐based organisations through effective communication management practices. ‘The art of progress is to preserve order amid change and to preserve change amid order’ — Alfred North Whitehead.

Abstract
In every industry there are resources. Some are moving, others more fixed; some are technical, others social. People working with the resources, for example, as buyers or sellers, or users or producers, may not make much notice of them. A product sells. A facility functions. The business relationship in which we make our money has “always” been there. However, some times this picture of order is disturbed. A user having purchased a product for decades may “suddenly” say to the producer that s/he does not appreciate the product. And a producer having received an order of a product that s/he thought was well known, may find it impossible to sell it. Such disturbances may be ignored. Or they can be used as a platform for development. In this study we investigate the latter option, theoretically and through real world data. Concerning theory we draw on the industrial network approach. We see industrial actors as part of (industrial) networks. In their activities actors use and produce resources. Moreover, the actors interact − bilaterally and multilaterally. This leads to development of resources and networks. Through “thick” descriptions of two cases we illustrate and try to understand the interactive character of resource development and how actors do business on features of resources. The cases are about a certain type of resource, a product − goat milk. The main message to industrial actors is that they should pay attention to that products can be co-created. Successful co-creation of products, moreover, may require development also of business relationships and their connections (“networking”).
