Information security management: An entangled research challenge

In May 2009 the Information Security Group, Royal Holloway, became host to a medical sociologist from St. George’s Hospital, University of London, under EPSRC’s discipline hopping scheme. As part of this knowledge transfer activity, a sociotechnical study group was formed comprising computer scientists, mathematicians, organisational researchers and a sociologist. The focus of this group is to consider different avenues of sociotechnical research in information security. This article briefly outlines some of the areas of research where sociotechnical studies might contribute to information security management.     

On the role of the Facilitator in information security risk assessment

In organisations where information security has historically been a part of management and for which the risk assessment methodologies have been designed there are established methods for communicating risk. This is the case for example in the banking and military sectors. However in organisations where information security is not embedded into management thinking and where the relationship between information security and the business is less clear-cut, communicating the risks to the business is less straightforward. In such circumstances it has been observed during field research that information security risk assessments frequently output findings to which the business cannot relate and the process is consequently often viewed as a “tick box” exercise, as opposed to one that provides real value to the business. In such a situation the information security risk assessment is divorced from the business process and not embedded into the organisation’s processes or thinking. The research for this paper was undertaken in order to identify what needs to be done in order to ensure that businesses of this type find the risk assessment process valuable in practice.

The effect of brominated epoxy on epoxy/phenolic reactive blends

Innovative reactive blends containing epoxy and brominated epoxy (BE) incorporated with resole-type phenolic were studied with the aim to elucidate the curing kinetics and the final thermomechanical characteristics of this unique system. Curing kinetics was investigated by means of the activation energy determined using differential scanning calorimetry (DSC ) at various heating rates analyzed by the Arrhenius equation. Both DSC and Fourier transform infrared revealed that bromine elimination at elevated temperatures (above 220 °C) had lowered the activation energy in the case of BE containing phenolic blends. The thermomechanical properties showed that the addition of conventional epoxy to resole decreased its thermal properties and modulus compared to neat resole. Distinctively, BE/resole blends exhibited increased glass-transition temperature, compared to diglycidyl ether of bisphenol A/resole blends in combination with higher elongation and toughness compared to neat resole. It was concluded that BE/epoxy resin/phenolic reactive systems offer high T _g, mechanical properties and toughness and hence are applicable for structural adhesives and for matrices of polymer-fiber composites. © 2018 Wiley Periodicals, Inc.

Toughening of epoxy systems by brominated epoxy

Blends of brominated epoxy (BE) and conventional epoxy resins were studied following curing with aliphatic triethylenetetramine (TETA), etheric (polyether diamine‐ PEA4), and aromatic (3,3′‐diamino diphenyl sulfone [DDS]) hardeners. The addition of BE resulted in an increase in T_g in all tested blends. Blends with 50 wt% BE cured with TETA demonstrated an increase in flexural modulus and flexural strength, while preserving the elongation. Blends with 40 wt% BE cured with PEA4 and 50 wt% BE cured with DDS resulted in a significant enhanced tensile elongation. The shear strength of all cured systems decreased moderately with the addition of BE exhibiting a mixed mode failure. Analysis of the fracture morphology using electron microscopy supported the increase of toughness levels as a result of incorporating BE to conventional epoxy. A unique nodular and rough fracture morphology was obtained, which is related to a toughening mechanism caused by the addition of BE. It was concluded that blends of BE and conventional epoxy could be used as structural adhesives having high T_g, enhanced mechanical properties and increased toughness. POLYM. ENG.

Irrigation energy use and related greenhouse gas emissions of maize production in Mexico

Maize is the most important crop grown in Mexico, with more than one-third of total production coming from irrigated fields. We compute irrigation energy use and associated greenhouse gas emissions of different irrigated maize systems in Mexico. Calculations were based on National Agriculture and Forestry Census 2007 microdata, irrigation water requirements estimated from state-level climate data, and energy and emission coefficients from the literature. Weighted average irrigation energy and related emissions are in the range of 1.0–31.6 GJ/ha and 62.0–2,019.9 kg CO₂e/ha, respectively, while country-scale estimates amount to 4.8 PJ and 305.2 Gg CO₂e.     

Energy consumption and related CO2 emissions in five Latin American countries: Changes from 1990 to 2006 and perspectives

This study examines the primary energy consumption and energy-related CO₂ emissions in Argentina, Brazil, Colombia, Mexico and Venezuela during the period 1990-2006. It also reviews important reforms in the energy sector of these countries as well as the promotion of energy efficiency (EE) and renewable energy sources (RES). Using a decomposition analysis, results indicate that even though significant reductions in energy intensity have been achieved in Colombia, Mexico and in a lesser extent in Brazil and Argentina, the reduction of CO₂ emissions in these countries has not been significant due to an increased dependence on fossil fuels in their energy mix. Although the Latin American region has an important experience in the promotion of EE programs and renewable sources, the energy agenda of the examined countries focused mostly on the energy reforms during the analyzed period. The policy review suggests that further governmental support and strong public policies towards a more sustainable energy path are required to encourage a low carbon future in the region.     

PrepHub Nepal

This article documents an action-research and collaborative-design process for building a disaster-prepared public space and water infrastructure in Thecho, Nepal. When the 2015 Gorkha earthquake devastated the country, public open spaces provided safety and resources post-disaster. The project identifies the paati, an existing public space typology, as the genius loci and embeds the paatis with new public infrastructure. Combining earthquake reconstruction, historical preservation, and risk reduction, the intervention provides improved daily water access and a safe space to gather post-disaster. Documenting and reflecting on this process illustrates the importance of ethnographic fieldwork and local partnerships in designing for a disaster-prepared public realm.     

The need for enhanced privacy and consent dialogues

The aim of this article is to present the case for a closer examination of the privacy and consent dialogues that take place during the use of on-line services. This article explores the concepts of privacy and consent in on-line services, discusses the facets of both concepts and presents a case study from Sunderland City Council to illustrate the complexity of deploying privacy and consent dialogue within on-line services. The article concludes with an outline of how enhanced understanding of privacy and consent concepts can result in improved tools to support dialogue and result in a negotiated understanding of the privacy that can be expected and the consent that it is required. This rationale is the underpinning of the VOME project – Visualisation and Other Methods of Expression – funded by TSB, EPSRC and ESRC.
