Phase-induced polarization method based on processing noise signals of the natural electromagnetic field of the Earth
Authors: Shaidurov G.Ya. , Potylitsyn V.S. , Kudinov D.S. 
Published: September 2016

Abstract
The paper deals with the physical fundamentals of the phase geoelectric method of induced polarization (IP) based on the extraction of information from the natural electromagnetic field of the Earth (NEMFE) in the frequency range 0.1–20.0 Hz. Scientific and technical justification is provided for the differential measurement circuit parameters of the NEMFE and the algorithm of processing of the received signals with the calculation of the IP coefficient, assuming the identity of the field characteristics in two receiving lines. The method consists in recording random noise signals from two adjacent receiving electrical dipoles with simultaneous memorizing of the amplitudes and their automatic equalization. Then the difference between the signals is calculated, with subsequent energy normalization. The presented theoretical fundamentals for the calculation of the IP coefficient of the NEMFE and the processing algorithm were tested in laboratory experiments. Under the assumption of the complete identity of the medium beneath the receiving dipoles, the IP coefficient was 0.01–0.03, due to the error in the elemental base of the analog input path. The paper also presents the results of field experiments on the Samson iron deposit in the Republic of Khakassia. The experimental work confirmed the effect of IP on the NEMFE in the anomalous area and showed that the results are consistent with theoretical and laboratory predictions and the data obtained using a KEP-M pulse system. It is concluded that this method can be used to detect productive anomalies and has an advantage of eliminating artificial sources of excitation of geologic sections.
On large deviation rates for sums associated with Galton‒Watson processes
Authors: He Hui 
Published: September 2016

Abstract
Given a supercritical Galton‒Watson process {Zn} and a positive sequence {εn}, we study the limiting behaviors of ℙ(SZn/Zn≥εn) with sums Sn of independent and identically distributed random variables Xi and m=𝔼[Z1]. We assume that we are in the Schröder case with 𝔼Z1 log Z1<∞ and X1 is in the domain of attraction of an α-stable law with 0<α<2. As a by-product, when Z1 is subexponentially distributed, we further obtain the convergence rate of Zn+1/Zn to m as n→∞.
Do Missing Domain Scores Compromise the Validity of the Quality of Life Inventory?
Authors: Thomas M. D. , McGrath A. , Skilbeck C. E. 
Published: September 2016

Background and aims: The Quality of Life Inventory (QOLI, Frisch, 1994) manual states that in most cases QOLI total scores are invalid when two or more of the 16-domain scores are missing. The current study aimed to investigate this guideline.Methods: Two samples were utilised consisting of 259 community-dwelling adults and 144 adults surveyed 12 months following traumatic brain injury (TBI). First, the domains of the QOLI were regressed against Quality of Life Index (QLI) total scores. Second, a series of Receiver Operator Curve analyses systematically investigated the sensitivity of QOLI scores in detecting depression, as identified by the HADS and DASS.Results: The final model predicting QLI scores comprised seven of the 16-QOLI domains, R2 = .57, and accounted for equivalent variance to the full 16-domain model, R2 = .59. With as few as seven domains, the sensitivity of QOLI scores in identifying participants with depression was very good and equivalent to the complete 16-QOLI domain total score (>76%). Similar results were observed when these analyses were replicated within the sample with TBI.Conclusions: These findings showed the QOLI was more robust to missing domain scores than the current validity guidelines stated in the scale's manual suggest. Future research could determine the core domains of the QOLI in a range of samples including adolescents and specific clinical groups.

OBJECTIVETo determine the source of aLegionella pneumophilaserogroup 5 nosocomial outbreak and the role of the heat exchanger installed on the hot water system within the previous year.SETTINGA 400-bed tertiary care university hospital in Sherbrooke, Canada.METHODSHot water samples were collected and cultured forL. pneumophilafrom 25 taps (baths and sinks) within wing A and 9 taps in wing B. Biofilm (5) and 2 L water samples (3) were collected within the heat exchangers forL. pneumophilaculture and detection of protists. Sequence-based typing was performed on strain DNA extracts and pulsed-field gel electrophoresis patterns were analyzed.RESULTSFollowing 2 cases of hospital-acquired legionellosis, the hot water system investigation revealed a large proportion ofL. pneumophilaserogroup 5 positive taps (22/25 in wing A and 5/9 in wing B). High positivity was also detected in the heat exchanger of wing A in water samples (3/3) and swabs from the heat exchanger (4/5). The outbreak genotyping investigation identified the hot water system as the source of infections. Genotyping results revealed that all isolated environmental strains harbored the same related pulsed-field gel electrophoresis pattern and sequence-based type.CONCLUSIONSTwo cases of hospital-acquired legionellosis occurred in the year following the installation of a heat exchanger to preheat hospital hot water. No cases were reported previously, although the sameL. pneumophilastrain was isolated from the hot water system in 1995. The heat exchanger promotedL. pneumophilagrowth and may have contributed to confirmed clinical cases.Infect. Control Hosp. Epidemiol.2016;1475–1480
Sensor Configuration Optimizing in Modal Identification by Siege ant Colony Algorithm
Authors: Feng S. , Jia J.-Q. , Zhang J.-C. 
Published: September 2016

AbstractProper monitor planning is a vital component of structural health monitoring (SHM) project. An extremely important part of the monitor planning is the placement of sensors, usually in the form of acceleration sensors. For the placement of three-dimensional acceleration sensors, the state of practice is to select the sensor configuration by previous experiences. However, this results in a waste of many sensors. A novel method called siege ant colony algorithm (SAC) is proposed in this paper. This method is built on the previous ant colony optimization (ACO) in the direction of improving efficiency and accuracy when applied to optimal sensor placement (OSP) problems in large-scale structure monitoring. This method is applied and compared with standard approaches using the Hanjiang transmission tower.
Experimental Study of Concrete Aging Effect on the Contact Force and Contact Time During the Impact Interaction of an Elastic Rod with a Viscoelastic Beam

Published: September 2016

AbstractIn the present paper, the low-velocity impact of an elastic rod with a flat end upon a viscoelastic Timoshenko type beam has been considered. Viscoelastic properties of the beam out of the contact zone are described by the standard linear solid model with integer derivatives, while inside this zone they are governed by the fractional derivative standard linear solid model. The contact force for a concrete target has been defined experimentally at the concrete age of 7, 14, 28, 56, and 91 days. It has been found that an average maximum of the contact force increases with concrete age, whereas the contact duration decreases. Moreover, the most remarkable changes of both, contact force and contact time, occur at the concrete age earlier than 14 days, after that the rate of changes slows down. Experimental results have a good coincidence with theoretical expectations.
Precursor motion to iceberg calving at Jakobshavn Isbræ, Greenland, observed with terrestrial radar interferometry

Published: September 2016

ABSTRACTTime-varying elevations near the calving front of Jakobshavn Isbræ, Greenland were observed with a terrestrial radar interferometer (TRI) in June 2015. An ice block with surface dimensions of 1370 m × 290 m calved on 10 June. TRI-generated time series show that ice elevation near the calving front began to increase 65 h prior to the event, and can be fit with a simple block rotation model. We hypothesize that subsurface melting at the base of the floating terminus breaks the gravity-buoyancy equilibrium, leading to slow subsidence and rotation of the block, and its eventual failure.
Cisnerospira(Brachiopoda, Spiriferinida), an atypical Early Jurassic spire bearer from the Subbetic Zone (SE Spain) and its significance

Published: September 2016

AbstractThe order Spiriferinida represented a significant group whose extinction is linked to the early Toarcian mass extinction event. The genusCisnerospiraManceñido, 2004, conspicuous representative of this group in the Early Jurassic of the western Tethys, is analyzed from a systematic standpoint, grounded mainly on evidence from the Subbetic domain, and its initial diagnosis is revised accordingly. A definitive suprageneric position within the subfamily Paralaballinae is formally proposed in the light of new data herein provided. Both external and internal diagnostic features and the generic and intraspecific variability are described through the analysis of theCisnerospiraspecies recorded in the easternmost Subbetic area, i.e.,Cisnerospira adscendens(Deslongchamps, 1858), C. aff.adscendens, C. angulata(Oppel, 1861), andC.?sylvia(Gemmellaro,1882). In addition, their interrelation with other records from several Tethyan basins is addressed, and the generic spectrum has been extended to include several species with high morphological affinity. This characterization thus contributes to clarify certain ambiguities in the systematics of the spiriferinids, which entails a complex taxonomy mainly based on the external features, where the ribbing pattern was given foremost classificatory value due to the lack of more reliable generic diagnostic criteria. Furthemore, a morphofunctional analysis performed inCisnerospirareveals a presumable epibenthonic libero-sessile way of life, and two alternative adaptive strategies are discussed: resting on and/or sticking in substrates with different degree of consolidation, providing a significant hydrodynamic stability to the shell.
An annotated bibliography of Arabic and Berber in Libya
Authors: Benkato Adam , Pereira Christophe 
Published: September 2016

AbstractThe Libyan varieties of both Arabic and Berber are among the least researched in their respective fields. In order to facilitate the study of these varieties, we present an annotated bibliography of all relevant research that could be identified up until the middle of 2016. With this, we aim to identify both the gaps in current and the possibilities for future research. Studies are grouped into Arabic and Berber sections, and subgrouped according to region. For Arabic, dialects of Tripoli and western regions, Benghazi and eastern regions, Fezzan and southern regions, as well as Jewish dialects, are treated. For Berber, varieties of Zwara, the Nafusa mountains, Sokna and El-Foqaha, and Awjila, and Tuareg are treated. Short introductions highlighting the most important studies precede bibliographic references and brief comments are given when of interest.

Published: September 2016

BackgroundThe different patterns of Emotional Intelligence (EI) deficits in schizophrenia and bipolar I disorder are are not yet well understood. This study compares EI levels among these groups and highlights the potential impact of non-social cognition on EI.MethodFifty-eight schizophrenia and 60 bipolar outpatients were investigated using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) and the Brief Assessment of Cognition in Schizophrenia (BACS). Analyses of covariance were performed with adjustment for the BACS composite score.ResultsCompared to bipolar subjects, schizophrenia patients showed significantly lower levels in both EI and non-social cognition. After adjustment for the BACS composite score, the difference in EI was lost. The mediation analysis revealed that differences between schizophrenia and bipolar patients in strategic EI are almost fully attributable to the mediating effect of non-social cognition.ConclusionsOur findings suggest that in both schizophrenia and bipolar patients EI is strongly influenced by non-social cognitive functioning. This has to be taken into account when interpreting MSCEIT data in comparative studies in serious mental illness and emphasizes the importance of cognitive remediation.

AbstractIntroductionThis study aimed to (a) examine eHealth literacy, beliefs, and behaviours in parents of children with complex CHD, and (b) identify parents’ preferences for the content, format, features, and functions of eHealth resources for CHD.Materials and methodsFamilies (n=198) of children born between 2008 and 2011 and diagnosed with CHD requiring surgery were mailed a survey assessing a range of variables including eHealth literacy, beliefs, and behaviours as well as preferences for the format, functions, features, and content of eHealth resources for CHD.ResultsA total of 132 parents (83 mothers, 49 fathers) completed the survey (response rate: 50%). Mothers (96%) were more likely to access eHealth resources than fathers (83%, χ2=6.74, p=0.009). Despite high eHealth resource use, eHealth literacy was relatively low, with results demonstrating considerable and widespread gaps in awareness of, access to, and communication about eHealth resources. Over 50% of parents reported that decisions regarding their child’s healthcare were influenced, to some extent, by web-based resources. Barriers to doctor–patient communication about eHealth included limited consultation time and concern about doctors’ disapproval. Participants demonstrated a strong desire for “eHealth prescriptions” from their child’s healthcare team, and perceived a wide range of eHealth topics as highly important, including treatment-related complications as well as physical, cognitive, and emotional development in children with CHD.DiscussionResults suggest a need for stronger, more proactive partnerships between clinicians, researchers, educators, technologists, and patients and families to bring about meaningful innovations in the development and implementation of eHealth interventions in paediatric cardiology.

Published: September 2016

AbstractIntroductionThe concept of response time with minimal interval is intimately related to the practice of emergency medicine. The factors influencing this time interval are poorly understood.ProblemIn a process of improvement of response time, the impact of the patient’s age on ambulance departure intervals was investigated.MethodThis was a 3-year observational study. Departure intervals of ambulances, according to age of patients, were analyzed and a multivariate analysis, according to time of day and suspected medical problem, was performed.ResultsA total of 44,113 missions were included, 2,417 (5.5%) in the pediatric group. Mean departure delay for the adult group was 152.9 seconds, whereas it was 149.3 seconds for the pediatric group (P=.018).ConclusionA statistically significant departure interval difference between missions for children and adults was found. The difference, however, probably was not significant from a clinical point of view (four seconds).SchneggB,PasquierM,CarronPN,YersinB,DamiF.Prehospital Emergency Medical Services departure interval: does patient age matter?Prehosp Disaster Med.2016;31(6):608–613.
Predicting Willingness-to-Pay a Premium for Integrated Pest Management Produce: A Logistic Approach
Authors: Govindasamy Ramu , Italia John , Adelaja Adesoji 
Published: September 2016

Pesticide residue has repeatedly been documented as a leading source of food safety concern among consumers. While many studies have presented aggregate, descriptive illustrations of consumer response to Integrated Pest Management (IPM), consumer willingness-to-pay a premium for IPM produce and the factors that determine such willingness have received relatively little research attention. Such information is critical in the marketing of IPM produce.This study empirically evaluates the demographic characteristics that influence consumers to pay a premium for IPM grown produce. Results indicate that females, those with higher annual incomes, younger individuals, and those who frequently purchase organic produce are all more likely to pay a premium for IPM produce.

Ensuring a Sustainable, Enduring Agriculture
Authors: Horne James E. 
Published: September 2016

During the farm crisis of the 1980s we began to better understand the inherent faults of an industrialized food system. Despite large gains in productivity, efficiency, and economies of size, thousands of farms were in foreclosure. Many farmers were overly extended in debt. Others were in trouble because of a combination of factors such as drought, low crop prices, high input prices, and the lack of competition in the marketplace. The end result was the loss of thousands of farmers and a subsequent decline in many rural communities.At the same time, a new vision of an enduring agriculture emerged. It was called sustainable agriculture. This new paradigm became attractive because it focused on solutions to the problems of the day. Sustainable agriculture offered hope to farmers that were willing to differentiate their product and add value to it, deal with ecological costs by using sustainable best management practices, and work to create equity in food system employment. Forming new links with consumers is enabling farmers to set their prices, and consumers are willing to pay to know more about their food.

Abstract

Objective
Little is known about customer purchases of foods and beverages from small and non-traditional food retailers (i.e. corner stores, gas-marts, dollar stores and pharmacies). The present study aimed to: (i) describe customer characteristics, shopping frequency and reasons for shopping at small and non-traditional food retailers; and (ii) describe food/beverage purchases and their nutritional quality, including differences across store type.

Design
Data were collected through customer intercept interviews. Nutritional quality of food/beverage purchases was analysed; a Healthy Eating Index-2010 (HEI-2010) score for purchases was created by aggregating participant purchases at each store.

Setting
Small and non-traditional food stores that were not WIC-authorized in Minneapolis and St. Paul, MN, USA.

Subjects
Customers (n 661) from 105 food retailers.

Results
Among participants, 29 % shopped at the store at least once daily; an additional 44 % shopped there at least once weekly. Most participants (74 %) cited convenient location as the primary draw to the store. Customers purchased a median of 2262 kJ (540 kcal), which varied by store type (P=0·04). The amount of added sugar far surpassed national dietary recommendations. At dollar stores, participants purchased a median of 5302 kJ (1266 kcal) for a median value of $US 2·89. Sugar-sweetened beverages were the most common purchase. The mean HEI-2010 score across all stores was 36·4.

Conclusions
Small and non-traditional food stores contribute to the urban food environment. Given the poor nutritional quality of purchases, findings support the need for interventions that address customer decision making in these stores.
Novel Polarizing Method for Light Microscopy

Published: September 2016

AbstractA test of the qualities of polarizing filters was performed for a set of specimens including a bulk Nicol prism, standard polaroids, and special polyvinyl alcohol (PVA)-iodine thin-film filters coated on both sides by vertically oriented carbon nanotubes. The residual transmission of polarizing filters depending on the incidence angle of polarized light was examined in detail. The superior quality of polarizing film filters treated with carbon nanotubes was found. This fact allows us to propose a new application for polarizing films with carbon nanotubes for a polarizing cover glass. In such a way the cover glass may serve as an analyzer in a light polarizing microscope. Some features of optical scheme arrangement for the polarizing technique are discussed. The polarizing cover glass allows elimination of depolarization of light, which is inserted in a microscope objective. Test results of the proposed polarizing technique attest to the efficiency of using the polarizing cover glass. The new scheme for polaroid arrangement shows image-contrast enhancement by several percent in comparison with the standard layout.
