Strengthening ASIS&T's chapters by enhancing communication between chapters and with SIGs
Authors: Agarwal Naresh 
Published: June 2014

AbstractEDITOR'S SUMMARYWhile the ASIS&T Annual Meeting is as excellent opportunity for information professionals to gather, the special interest groups (SIGs) and chapters support interaction year‐round. SIGs bring together members focusing on 21 areas of interest, while 20 chapters are organized by region, with 43 university‐based student chapters. Each group operates under a governance committee or assembly, works through the year to deliver stimulating educational programs, projects and services and to recruit and retain members, and submits annual reports on their efforts. A shared challenge rises from a tendency toward one‐way communication to members from the Association, chapters or SIGs, an obstacle that can be overcome through deeper use of the ASIS&T's rich web content for members and involvement in chapter and SIG leadership. A number of resources are available to group officers to support SIG and chapter initiatives and administration. Sharing best practices though reports, awards and virtual meetings strengthens all groups and the Association as a whole.
ASIS&T: The student perspective
Authors: Dumas Catherine , Rorissa Abebe 
Published: June 2014

AbstractEDITOR'S SUMMARYAn engaged student membership is a key source of strength and vitality for a professional organization like ASIS&T. With 43 student chapters around the world, ASIS&T has a good foundation of student support; having an active chapter at each university with studies in information science would further strengthen the Association. An early 2014 survey elicited responses from 38 current or past students, 28 of whom had a local ASIS&T student chapter with 23 being members. Just over half had attended an ASIS&T Annual Meeting. Respondents noted the value of networking within the Association and special interest groups and the assistance available for career and research goals. They also observed drawbacks including the cost of Annual Meeting attendance and feeling lost at the large conference. Students are drawn by the opportunities for involvement and networking. Among the numerous suggestions offered to strengthen and enrich the student experience were leadership training, practical skill development and improved communications.
We've built it, but are they coming? International participation in ASIS&T online educational offerings
Authors: Abbas June M. , Pennington Diane Rasmussen 
Published: June 2014

AbstractEDITOR'S SUMMARYASIS&T has offered 55 educational webinars on key topics in information science since 2010, originally prompted by the Webinar Task Force. The successor Online Education Task Force broadened the goal to promote online education and communication among the membership and was followed by the Web Presence Task Force, which aims to bolster the Association's online presence overall, starting with a website redesign. The ASIS&T website offers members the potential for professional development and networking, and online channels are being explored to enhance engagement for all members, especially international members and those unable to attend Annual Meetings. A spring 2014 survey revealed that, while 75 percent of site visitors were from the United States, a substantial number represented India, European nations and North/East Asian countries. Webinar registration is strong for international members and visitors. Based on these indicators, several recommendations are offered to drive ongoing education, international outreach and recruitment efforts.
Google, tear down this wall to exploratory search!
Authors: Cole Charles 
Published: June 2014

AbstractEDITOR'S SUMMARYWhile Google serves traditional search needs adequately, it provides no assistance with exploratory search, unable to help a searcher crystallize a search goal. Evolutionary psychology illustrates a gradually developing search for meaning, combining beliefs with discovered knowledge, to expand a perceptual‐cognitive system. Similarly the information searcher progressively opens his or her cognitive system upon interacting with unfamiliar stimuli. The interactions typically occur in a series, with each new discovery or set of search results being associated with prior knowledge and other information sources, modifying the information need and helping to refine the search goal. This exploratory process may be followed by a command search for evidence to back up a thesis, a phase that Google serves well. An interactive, assisted, exploratory search is proposed. It has been demonstrated in Astrolabe, a prototype virtual search environment, and could be incorporated into the Google search engine.

ObjectivesTo conduct a meta‐analysis on surrogate and clinical outcomes with myocardial ischemic postconditioning (IPoC) following revascularization with primary percutaneous intervention (PPCI) for ST‐segment myocardial infarction (STEMI) compared with PPCI alone.BackgroundReperfusion injury remains an important problem following PPCI for STEMI. Trials of IPoC have mainly focused on cardiac biomarkers; the impact on clinical outcomes is unknown.MethodsClinical trials that randomized STEMI patients to IPoC as compared with conventional PPCI were included for analysis.ResultsA total of 15 randomized trials with 1,545 patients met our selection criteria (785 underwent IPoC + PPCI, 760 PPCI alone). Mean follow‐up for clinical outcomes was 4.7 months. The mean ischemic time was 225 min. ST‐segment resolution (Relative Risk [RR] = 0.98; 95% Confidence Intervals [CI] 0.85–1.13; P = 0.75) and infarct size (Weighted mean difference [WMD] = −2.53%, 95% CI −6.10 to 1.05; P = 0.17) were similar between the IPoC + PPCI vs. PPCI arms. Left ventricular ejection fraction at follow‐up was marginally higher in the IPoC (WMD = 4.15%, 95% CI 0.19–8.12%, P = 0.04). No differences were noted in any of the clinical outcomes studied, including mortality (RR = 1.52; 95% CI 0.77–2.99; P = 0.23), recurrent MI (RR = 3.04; 95% CI 0.74–12.54; P = 0.12); stent thrombosis (RR = 1.24, 95% CI 0.51–3.04; P = 0.83) or the composite MACE outcome (RR = 1.53; 95% CI 0.89–2.63; P = 0.13). Conclusions: IPoC following PPCI is not associated with improvements in surrogate or clinical outcomes at 5 months as compared with PPCI alone. Our findings indicate no role for IPoC in the routine management of patients with STEMI. © 2014 Wiley Periodicals, Inc.
Reporting an experience on design and implementation of e‐Health systems on Azure cloud
Authors: Lu Shilin , Ranjan Rajiv , Strazdins Peter 
Published: June 2014

SummaryElectronic Health (e‐Health) technology has brought the world with significant transformation from traditional paper‐based medical practice to Information and Communication Technologies (ICT)‐based systems for automatic management (storage, processing, and archiving) of information. Traditionally, e‐Health systems have been designed to operate within stovepipes on dedicated networks, physical computers, and locally managed software platforms that make it susceptible to many serious limitations including: (1) lack of on‐demand scalability during critical situations, (2) high administrative overheads and costs, and (3) inefficient resource utilization and energy consumption due to lack of automation. In this paper, we present an approach to migrate the ICT systems in the e‐Health sector from traditional in‐house Client/Server (C/S) architecture to the virtualized cloud computing environment. To this end, we developed two cloud‐based e‐Health applications (Medical Practice Management System and Telemedicine Practice System) for demonstrating how cloud services can be leveraged for developing and deploying such applications. The Windows Azure cloud computing platform is selected as an example public cloud platform for our study. We conducted several performance evaluation experiments to understand the QoS tradeoffs of our applications under variable workload on Azure. Copyright © 2014 John Wiley & Sons, Ltd.
Determination of GHB in human hair by HPLC‐MS/MS: Development and validation of a method and application to a study group and three possible single exposure cases

Published: June 2014

Gamma‐hydroxybutyrate (GHB) over the last two decades has generated increased notoriety as a euphoric and disinhibiting drug of abuse in cases of drug‐related sexual assault and for this reason it is considered a ‘date rape’ drug.The first aim of this paper was to develop and fully validate a method for the detection of GHB in human hair by high performance liquid chromatography‐tandem mass spectrometry (HPLC‐MS/MS) after liquid‐liquid extraction (LLE).The second aim was the application of the method to hair samples of 30 GHB‐free users in order to determine the basal level. The results obtained showed no significant differences in endogenous concentrations (p = 0.556) between hair samples of the three groups (black, blonde, and dyed hair) and the age and sex of the subjects did not affect the endogenous levels. Another 12 healthy volunteers, with no previous history of GHB use, were selected and a single dose (25 mg/Kg) was orally administered to all of them and hair samples were collected before the administration of the single dose and other two samples were collected one month and two months later, respectively. The segmental analysis of the latter two samples allowed us to calculate two ratios: 4.45:1 (95% C.I. 3.52–5.63) and 3.35:1 (95% C.I. 2.14–5.18), respectively, which can be recommended as reasonable values for a positive identification of GHB intake.Finally the method was applied to three real cases where a GHB single exposure probably occurred.

Relationship between Creeping Discharge along Aerial Insulated Cable and Duration of Wave Front of Inductive Lightning Surge
Authors: Nishi Toshiyuki , Hanaoka Ryoichi , Takata Shinzo 
Published: June 2014

SUMMARYWe report the results obtained on the developing characteristics of creeping discharges along the insulated cable surface under inductive lightning surge voltages with various durations of wave front. The aerial insulated cables, usually, are supported by the post insulator and the binding wire at the reinforced concrete pole. When a lightning strikes near by the aerial insulated cables, the overvoltage due to the inductive lightning surge invades to the central line of the cable. The creeping discharge can develop along the cable surface from the free end of the binding wire just after a flashover of the post insulator at the cable supporting point. This creeping discharge may give rise to the accidents such as a melting or snapping of the cable. An important subject to prevent these accidents is to clarify the characteristics of creeping discharge along the cable surface and the developing mechanism of discharges. In this study, the impulse voltages with various durations of wave front are applied to the central line of the wire as the inductive lightning surge. The length and aspect of positive and negative creeping discharges developing along the cable surface are measured using a still camera with an image intensifier, and the developing mechanisms of creeping discharges are discussed on the basis of the models which are proposed taking into account the obtained results.

AbstractWe modified a passive capillary sampler (PCS) to collect snowmelt water for isotopic analysis. Past applications of PCSs have been to sample soil water, but the novel aspect of this study was the placement of the PCSs at the ground‐snowpack interface to collect snowmelt. We deployed arrays of PCSs at 11 sites in ten partner countries on five continents representing a range of climate and snow cover worldwide. The PCS reliably collected snowmelt at all sites and caused negligible evaporative fractionation effects in the samples. PCS is low‐cost, easy to install, and collects a representative integrated snowmelt sample throughout the melt season or at the melt event scale. Unlike snow cores, the PCS collects the water that would actually infiltrate the soil; thus, its isotopic composition is appropriate to use for tracing snowmelt water through the hydrologic cycle. The purpose of this Briefing is to show the potential advantages of PCSs and recommend guidelines for constructing and installing them based on our preliminary results from two snowmelt seasons.

ASSESSMENT OF GROUNDWATER MANAGEMENT USING MODFLOW AND BENEFIT–COST ANALYSIS
Authors: Bozic Mile , Nikolic Goran , Milosev Dejan , Rudic Zeljka , Tomovic Sreten 
Published: June 2014

ABSTRACTThe objective of this paper is to present the application of systematic analyses to ascertain better groundwater management in agricultural and urban areas. The mentioned analyses encompass mathematical modelling (MODFLOW), and benefit–cost analysis. The Pancevacki Rit area is particularly suitable for these analyses, since it has a long history regarding excess water. The simulation model of Pancevacki Rit is used to develop an optimal drainage strategy for long‐term management. The existing canal network, with a density of 25 m ha−1 and 7 pumping stations with an installed capacity of 35.8 m3 s−1, are not sufficient to protect total area of 33 820 ha, mostly due to inefficient management. Initially the results of the mathematical model were used to select an acceptable drainage solution for the study area, with several stages distinguished (phases 1–5) and degrees of achieved protection. Introduction of economic evaluation (benefit–cost) made further differences between solutions, thus simplifying the choice. The most complex and effective solution involves a major total investment (€16 million), but minor unit investment costs (€ 400 ha−1) and the greatest benefit–cost ratio.

Readmission penalties and health insurance expansions: A dispatch from Massachusetts
Authors: Chen Christopher , Scheffler Gabriel , Chandra Amitabh 
Published: June 2014

BACKGROUNDPayers are penalizing hospitals for high readmission rates. It is unknown whether major changes in population insurance coverage can affect readmission rates, despite the Affordable Care Act's coverage expansions coming into effect this year.OBJECTIVETo evaluate the impact of a large‐scale insurance expansion on hospital readmissions, using Massachusetts' 2006 health reform as a natural experiment.DESIGNDifference‐in‐difference time‐series design.SETTINGAll Massachusetts acute‐care hospitals.PATIENTSInpatient visits from 2004 to 2010.MEASUREMENTSPrimary outcome was the hospital 30‐day readmission rate. Readmissions to any Massachusetts hospital were tracked.RESULTSDecreases in uninsurance rates during and after reform were largely limited to the hospital quartile with the highest prereform uninsurance rates (from 14% uninsured at the start of the reform to 2.9% by the end of the study period). The other hospitals collectively experienced a smaller decline in their uninsured admissions (5.9% at the start of reform to 2.5% by the end of the study period). According to difference‐in‐difference regression analysis, the highest uninsured hospital quartile experienced a modest increase in their unadjusted readmission rate of 0.6 percentage points (95% confidence interval: 0.1%–1.1%) during the reform period as compared to the other hospital quartiles (P = 0.01). This represents a relative increase of 4.5% in the readmission rate. Risk‐adjusted readmission rates showed no corresponding change.CONCLUSIONSThe Affordable Care Act's insurance expansion may be associated with an increase in unadjusted readmission rates among hospitals that cared for disproportionate numbers of uninsured patients. Risk‐adjustment appears to take this effect into account. Journal of Hospital Medicine 2014;9:681–687. © 2014 Society of Hospital Medicine
Inequality in Maternal Health Care Utilisation in India: A Shapley Decomposition Analysis
Authors: Pal Rama 
Published: June 2014

AbstractThe paper aims at decomposing income‐related inequality in maternal health care utilisation in India using the Shapley value method. In India, the usage of maternal health care services remains low with highly uneven access across socio‐economic groups. We analyse the income‐related inequality in maternal health care utilisation and its determinants. The decomposition results show that the demand side variables, namely, economic status of household and education of parents, are important factors determining inequality in utilisation. Also, we find that availability of government health care facilities in village and implementation of Janani Suraksha Yojana in village do not reduce income‐related inequality in utilisation.

Published: June 2014

ObjectiveTo determine the prevalence of doctor shopping resulting from differential treatment and to examine associations between this shopping and current primary care relationships.MethodsIn 2012, a national internet‐based survey of 600 adults receiving primary care in the past year with a BMI ≥ 25 kg/m2 was conducted. Our independent variable was “switching doctors because I felt treated differently because of my weight.” Logistic regression models to examine the association of prior doctor shopping with characteristics of current primary care relationships: duration, trust in primary care provider (PCP), and perceived PCP weight‐related judgment, adjusted for patient factors were used.ResultsOverall, 13% of adults with overweight/obesity reported previously doctor shopping resulting from differential treatment. Prior shoppers were more likely to report shorter durations of their current relationships [73% vs. 52%; p = 0.01] or perceive that their current PCP judged them because of their weight [74% vs. 11%; p < 0.01] than nonshoppers. No significant differences in reporting high trust in current PCPs were found.ConclusionsA subset of patients with overweight/obesity doctor shop resulting from perceived differential treatment. These prior negative experiences have no association with trust in current relationships, but our results suggest that patients may remain sensitive to provider weight bias.
An enhanced Kerberos protocol with non‐interactive zero‐knowledge proof
Authors: Zhu Yuesheng , Ma Limin , Zhang Jinjiang 
Published: June 2014

AbstractAs one of the most important trusted third‐party‐based authentication protocols, Kerberos is widely used to provide authentication service in distributed networks. However, it is vulnerable to common brute force password‐guessing attacks because of its password‐based mechanism. Some enhanced Kerberos protocols based on public key cryptography were proposed as solutions, but they require excessive computation and communication resources. In this paper, a new enhanced Kerberos protocol with non‐interactive zero‐knowledge proof is proposed, in which the clients and the authentication server can mutually authenticate each other without revealing any information during the authentication process. Our security analysis and experimental results have shown that the proposed scheme can resist password‐guessing attacks and is more convenient and efficient than previous schemes.

Surface wind speed reconstruction from synoptic pressure fields: machine learning versus weather regimes classification techniques
Authors: Saavedra‐Moreno B. , de la Iglesia A. , Magdalena‐Saiz J. , Carro‐Calvo L. , Durán L. , Salcedo‐Sanz S. 
Published: June 2014

AbstractThis paper tackles a problem of surface wind speed reconstruction based on synoptic‐scale meteorological fields. Specifically, two different approaches are discussed and compared: a pure Machine Learning method, formed by a Support Vector Regression and a genetic algorithm that only considers synoptic pressure as input variable, and a Weather Regimes Classification Technique, based on a k‐means clustering of the main three principal components of the geopotential height field and a simple, but efficient, linear regression between the surface pressure gradient and the observed surface wind. Both algorithms are shown to be accurate enough for wind speed reconstruction at medium latitude regions, even when there are only a few years of observations. These methodologies can also be used for filling gaps in wind speed series and, with some modifications and further research, they could be used for wind speed forecasting. The algorithms proposed are fully described and compared in this paper, and their performance has been comparatively evaluated in several real problems of wind speed reconstruction at three sites (Cabauw (The Netherlands), Capel (Wales, UK) and Kaegnes (Denmark)), obtaining excellent results in terms of wind speed reconstruction with moderate complexity in data processing and algorithms.

Published: June 2014

Abstract
Fusaricidin, a lipodepsipeptide isolated from Paenibacillus polymyxa, has high antimicrobial activity against fungi and Gram-positive bacteria. Through mutagenesis, we obtained two mutant strains, N1U7 and N17U7, which produce 6.2- to 7.9-fold more fusaricidin than their parent strain. Causal mutations were identified by whole-genome sequencing, and the two strains each contained at least eleven point mutations, including four common mutations. A mutation in the PPE04441 gene (pgm), encoding an α-phosphoglucomutase, was found to be an important factor in fusaricidin overproduction by complementation experiments. Null mutation of pgm in the parental strain increased fusaricidin production by 5.2-fold. Increased growth and cell viability in stationary phase, reduced exopolysaccharide production, and increased fusA expression were observed in the pgm mutant strains, which might be related to fusaricidin overproduction. This is the first report revealing that PGM deficiency leads to an overproduction of fusaricidin.
