Impact of Cyber-Security Issues on Smart Grid

Greater complexity and interconnectivity across systems embracing Smart Grid technologies has meant that cyber-security issues have attracted significant attention. This paper describes pertinent cyber-security requirements, in particular cyber attacks and countermeasures which are critical for reliable Smart Grid operation. Relevant published literature is presented for critical aspects of Smart Grid cyber-security, such as vulnerability, interdependency, simulation, and standards. Furthermore, a preliminary study case is given which demonstrates the impact of a cyber attack which violates the integrity of data on the load management of real power system. Finally, the paper proposes future work plan which focuses on applying intrusion detection and prevention technology to address cyber-security issues. This paper also provides an overview of Smart Grid cyber-security with reference to related cross-disciplinary research topics.

Women Speaking of National Security: The Case of Checkpoint Watch

The production of reports and the distribution of information have become integral to the operation of many non-governmental organizations. In this regard, the fact that the all-women organization of Checkpoint Watch publishes reports about the Israeli checkpoints in the occupied West Bank seems to comply with current trends. However, the reports—most of which are short repetitive descriptions of the banality and everydayness of the military checkpoints, counting the number of people and cars waiting, commenting on the manner in which the checks are performed and meticulously documenting what mostly amounts to minor incidents of humiliation and distress—do not seem to abide by any convention of reporting. This work analyzes the reporting praxis of the organization and claims that it should be understood as a form of activism in and of itself. Tracking the ways in which the reports address the Israeli public through the concept of parrhesia, the work suggests that this form of reporting enables the women activists to use their gendered marginality to make their way into the highly masculinized and militarized Israeli security discourse.

Uniformity of visual acuity measures in published studies

PURPOSE. To investigate the methods used in contemporary ophthalmic literature to designate visual acuity (VA). METHODS. Papers in all 2005 editions of five ophthalmic journals were considered. Papers were included if (1) VA, vision, or visual function was mentioned in the abstract and (2) if the study involved age-related macular degeneration, cataract, or refractive surgery. If a paper was selected on the basis of its abstract, the full text of the paper was examined for information on the method of refractive correction during VA testing, type of chart used to measure VA, specifics concerning chart features, testing protocols, and data analysis and means of expressing VA in results. RESULTS. One hundred twenty-eight papers were included. The most common type of charts used were described as logMAR-based. Although most (89.8%) of the studies reported on the method of refractive correction during VA testing, only 58.6% gave the chart design, and less than 12% gave any information whatsoever on chart features or measurement procedures used. CONCLUSIONS. The methods used and the approach to analysis were rarely described in sufficient detail to allow others to replicate the study being reported. Sufficient detail should be given on VA measurement to enable others to duplicate the research. The authors suggest that charts adhering to Bailey-Lovie design principles always be used to measure vision in prospective studies and their use encouraged in clinical settings. The distinction between the terms logMAR, an acuity notation, and Bailey-Lovie or ETDRS as chart types should be adhered to more strictly.

Overview of clinical outcome measures used in glaucoma randomised controlled trials (RCTs)

Background: In clinical trials the selection of appropriate outcomes is crucial to the assessment of whether one intervention is better than another. Glaucoma is a chronic eye disease and the leading cause of irreversible blindness in the world. A variety of outcomes has been used and reported in glaucoma RCTs.

Objectives: The purpose of this review is to identify different clinical outcome measures used in glaucoma RCTs between January 2006 and March 2012.

Methods: A systematic review was conducted using standard methodology. We searched for RCTs in glaucoma published in English with no restrictions on the population type or size, or applied interventions. All clinical outcomes were included. Patient-reported, pharmacokinetic and economic outcomes were excluded.

Results: The search strategy identified 4288 potentially relevant abstracts. There were 315 publications retrieved, of which 233 RCTs were included. A total of 967 clinical measures were reported. There were large variations in the definitions used to describe different outcomes and their measures. Intraocular pressure (IOP) was the most commonly reported outcome (used in 201 RCTs, 86%) with a total of 422 measures (44%). Amongst the IOPrelated measures, the most commonly used was mean IOP (n=143, 15% of all measures). Safety outcomes were commonly reported, in 145 RCTs (62%) whereas visual field outcomes were utilized in 38 RCTs (16%).

Conclusions: There is a large variability in clinical outcomes used for glaucoma RCTs and in the way each outcome is reported. This lack of standardisation may impair the ability to evaluate the evidence of glaucoma interventions.

Exodus? The training paths and plans of postgraduate medical trainees, under the Royal College of Physicians of Ireland

Background: In 2006, the Buttimer report highlighted the paucity of demographic data on those applying for and entering postgraduate medical education and training (PGMET) in Ireland. Today, concerns that there is an "exodus" of graduates of Irish medical schools are at the forefront of national discussion, however, published data on PGMET remains inadequate.

Aims: The objectives of this study were to collate existing data relating to trainees and training programmes at three stages of training and to examine the career plans of junior trainees.

Methods: Data from application forms for training programmes, commencing July 2012, under the Royal College of Physicians of Ireland (n = 870), were integrated with data from other existing sources. Candidates entering basic specialist training were surveyed with regard to career plans. Descriptive and comparative analysis was performed in SPSS version 18.

Results: Graduates of Irish medical schools made up over 70 % of appointees. Over 80 % of BST trainees aspired to work as consultants in Ireland, but 92.5 % planned to spend time working abroad (response rate 77 %). Decisions to leave the Irish system were linked to lifestyle, but also to failure to be appointed to higher specialist training. Significant numbers of trainees return to Ireland after a period abroad.

Conclusions: The trainee "exodus" is more complex than is often portrayed. The desire to spend time working outside Ireland must be accounted for in workforce planning and configuration of training programmes. Expansion of HST is a potential solution to reduce the numbers of graduates leaving Ireland post-BST.

Small area estimation for the price of habitation transaction: comparison of different uncertainty measures of temporal EBLUP

Local level planning requires statistics for small areas, but normally due to cost or logistic constraints, sample surveys are often planned to provide reliable estimates only for large geographical regions and large subgroups of a population.

Using data envelopment analysis to assess the efficiency of social security systems: the case of income protection in old age

As the number of pensioners in Europe rises relative to the number of people in employment, the gap between the contributions and the benefit levels increases, and consequently ensuring adequate pensions on a sustainable basis has become a major challenge. This study aims to explore the potential of using the Data Envelopment Analysis (DEA) technique in order to access the efficiency of the income protection in old age, one of the most important branches of Social Security. To this effect, we collected data from the 27 European Union Member States regarding this branch. Our results show important differences among the Member States and stress the importance of identifying best practices to achieve more adequate, sustainable and modernised pension systems. Our results also highlight the importance of using DEA as a decision support tool for policy makers.
