Abstract
Purpose
The purpose of this paper is to formulate a novel model for enhancing the effectiveness of existing digital forensic readiness (DFR) schemes by leveraging the capabilities of cyber threat information sharing.
Design/methodology/approach
This paper uses a quantitative methodology to identify the most popular cyber threat intelligence (CTI) elements and introduces a lightweight approach to correlate those with potential forensic value, resulting in the quick and accurate triaging and identification of patterns of malicious activities.
Findings
While threat intelligence exchange steadily becomes a common practice for the prevention or detection of security incidents, the proposed approach highlights its usefulness for the digital forensics (DF) domain.
Originality/value
The proposed model can help organizations to improve their DFR posture, and thus minimize the time and cost of cybercrime incidents.

Abstract
Purpose
The purpose of the paper is to present a framework for moving cross-border ePrescription (eP) and Patient Summary (PS) services forward, bearing in mind the needs and requirements of the European e-health space for cross-border eP and PS services, the limitations of the already developed solutions, as well as outcomes available from other domains.
Design/methodology/approach
The outcomes of previous and current large-scale pilot projects, aiming toward the delivery of electronic cross-border services, are examined. Integration of generic building blocks (BBs) is considered for the further development of cross-border eP and PS, in line with the European Directive on patients’ rights in cross-border health care.
Findings
The e-health domain is expected to greatly benefit from mitigating non-domain concerns such as those for electronic identification, end point detection, non-repudiation and the use of electronic signatures and trust establishments for basic cross-border public services in Europe.
Research limitations/implications
Research limitations are related to the fact that electronic identification, electronic signature and semantic issues have not been fully addressed yet at a European level to support cross-border services.
Practical implications
Practical implications are related to the cooperation, European level compatibility and sustainability of the underlying national infrastructures required to support reliable and secure exchange of medical data, as well as the readiness to address continuously evolving interoperability, legal and security requirements in a cross-border setting.
Originality/value
The need for consolidating the existing outcomes of non-health specific BBs is examined for two high-priority e-health services. Ongoing progress is presented, together with related issues that need to be resolved for improving technical certainty and making it easier to use health-care services abroad in cases of emergency.

Abstract
Since 2008, Greece has been spiralling down an economic and socio-political crisis. Over the past decade, it has endured massive riots, consecutive elections, a debilitating public debt, and endless rescue plans by the EU and other international bodies. The crisis sparked an intense interest in the Greek public discourse, which is often accused of being dominated by populist rhetoric. This interest appears to be accompanied predominantly by a certain leitmotif: instead of appreciating the assistance offered, the Greek people resent it and taking refuge in populist rhetoric, further undermining the country’s stability. This echoes the age-old argument that ‘the people are an irrational mob acting impulsively, a lamentable state that should be cured or disciplined.’ Could the shaming, the appeal to sober morality – branding all other discourses as populist and dangerous – be the fashionable response of a cosmopolitan elite, high-profile pundits and institutions to the problems of global capitalism? The debate raged in the public sphere and in the streets of Athens. On multiple occasions, the crisis was used as a trope in the European public sphere to justify socio-political changes, austerity measures and disciplinary actions. The emerging schema juxtaposed populist/anti-populist discourses, reducing discourses and identities to black and white. This chapter reads discursive constructions of the Greek crisis, by-stepping the populist/anti-populist divide. Using analysis based on affect theory and the philosophy of emotions, it investigates the various uses of resentment as part of affective engineering and as an instrument of collective identification, in an environment of multiple overlapping crises in Europe.

Abstract
Purpose
The purpose of this paper is to study the main landing gear (MLG) mechanism configuration.
Design/methodology/approach
Mechanism kinematics and dynamics, stress analysis and sizing of the MLG structural members, and fatigue issues related with the mechanism operation. Spreadsheet solutions were incorporated to this survey to analyze the most conceivable loading situations, and important factors of the mechanism design for an initial evaluation of safety implications.
Findings
MLG design approach along with conservative fatigue design factors lies in the area of accepted limits in commercial aircraft industry.
Research limitations/implications
MLG loading associated with landing as well as those associated with ground maneuvers (steering, braking and taxiing) contribute significantly to fatigue damage, along with the stresses induced by manufacturing processes and assembly. The application of FEA methods for the design of the landing gear does not always guarantee a successful approach to the problem solution, if precise analytical solutions are not available in advance.
Practical implications
From the investigation of this incident of fractured struts of the MLG it is confirmed that the reduction in Pintle Housing diameter on the upper part has contributed to the avoidance of damaging the fuel tank above the MLG that would lead to a catastrophic event. On the other hand, the airframe of the SKY-Jet was proved efficient for a belly landing with minor damages to the passengers and heavier damages for the aircraft.
Social implications
On-line vibration monitoring sensors hooked up to the landing gear strut and Pintle House would greatly enhance safety, without relying in optical surveys in hard to access and inspect areas of the landing gears mechanisms housings.
Originality/value
Analytic methods were adopted and spreadsheet solutions were developed for the MLG main loading situations, along with design issues concerning mechanism kinematics and dynamics, stress analysis and sizing of the MLG structural members, as well as fatigue issues related with the mechanism operation. Spreadsheet solutions were incorporated to this survey to analyze the most conceivable loading situations, and important factors of the mechanism design for an initial evaluation of safety implications.

Abstract
This chapter demonstrates that while in most late modern societies there is a neoliberal hegemony to expand police Closed-Circuit Television (CCTV) surveillance for crime control and antiterrorism, in Greece there is serious controversy and resistance against the post-Olympic use of more than 1,200 Olympic CCTV cameras. Drawing on the interesting politics of CCTV expansion and resistance, the chapter traces the reasons why, in the Greek context, this very expensive Olympic surveillance “dowry” has been opposed, even for traffic control. It critically attributes Greek citizens’ fear and mistrust primarily to their past police-state experience of authoritarian, thought-control surveillance.
