Did Blue Cross and Blue Shield Suffer from Adverse Selection? Evidence from the 1950s
This paper uses a unique data set from 1957 to examine whether or not Blue Cross and Blue Shield suffered from an adverse selection death spiral after for-profit commercial insurance companies entered the market for health insurance. Results suggest that moving to experience rating may have helped the Blues counteract adverse selection in the group health insurance market. Adverse selection posed a greater problem for the Blues in the market for individual health insurance, possibly because of differences in the way the Blues screened potential enrollees relative to commercial insurance companies.
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
SHIELD: A Novel NFV-based Cybersecurity Framework
SHIELD is an EU-funded project, targeting at the design and development of a novel cybersecurity framework, which offers security-as-a-Service in an evolved telco environment. The SHIELD framework leverages NFV (Network Functions Virtualization) and SDN (Software-Defined Networking) for virtualization and dynamic placement of virtualised security appliances in the network (virtual Network Security Functions – vNSFs), Big Data analytics for real-time incident detection and mitigation, as well as attestation techniques for securing both the infrastructure and the services. This papers discusses key use cases and requirements for the SHIELD framework and presents a high-level architectural approach

The impact of sound field systems on learning and attention in elementary school classrooms
Purpose: An evaluation of the installation and use of sound field systems (SFS) was carried out to investigate their impact on teaching and learning in elementary school classrooms. Methods: The evaluation included acoustic surveys of classrooms, questionnaire surveys of students and teachers and experimental testing of students with and without the use of SFS. Students ’ perceptions of classroom environments and objective data evaluating change in performance on cognitive and academic assessments with amplification over a six month period are reported. Results: Teachers were positive about the use of SFS in improving children’s listening and attention to verbal instructions. Over time students in amplified classrooms did not differ from those in nonamplified classrooms in their reports of listening conditions, nor did their performance differ in measures of numeracy, reading or spelling. Use of SFS in the classrooms resulted in significantly larger gains in performance in the number of correct items on the nonverbal measure of speed of processing and the measure of listening comprehension. Analysis controlling for classroom acoustics indicated that students ’ listening comprehension score
Shield laws in Australia: Legal and ethical implications for journalists and their confidential sources
This article examines whether Australia's current shield law regime meets journalists' expectations and whistleblower needs in an era of unprecedented official surveillance capabilities. According to the peak journalists' organisation, the Media, Entertainment and Arts Alliance (MEAA), two recent Australian court cases 'despite their welcome outcome for our members, clearly demonstrate Australia's patchy and disparate journalist shields fail to do their job' (MEAA, 2014a). Journalists' recent court experiences exposed particular shield law inadequacies, including curious omissions or ambiguities in legislative drafting (Fernandez, 2014c, p. 131); the 'unusual difficulty' that a case may present (Hancock Prospecting No 2, 2014, para 7); the absence of definitive statutory protection in three jurisdictions-Queensland, South Australia and the Northern Territory (Fernandez, 2014b, p. 26); and the absence of uniform shield laws where such law is available (Fernandez, 2014b, pp. 26-28). This article examines the following key findings of a national survey of practising journalists: (a) participants' general profile; (b) familiarity with shield laws; (c) perceptions of shield law effectiveness and coverage; (d) perceptions of story outcomes when relying on confidential sources; and (e) concerns about official surveillance and enforcement. The conclusion briefly considers the significance and limitations of this research; future research directions; some reform and training directions; and notes that the considerable efforts to secure shield laws in Australia might be jeopardised without better training of journalists about the laws themselves and how surveillance technologies and powers might compromise source confidentiality.Full Tex
