Abstract
Characterizing ecological relationships between viruses, bacteria and protists in the ocean are critical to understanding ecosystem function, yet these relationships are infrequently investigated together. We evaluated these relationships through microbial association network analysis of samples collected approximately monthly from March 2008 to January 2011 in the surface ocean (0–5 m) at the San Pedro Ocean Time series station. Bacterial, T4-like myoviral and protistan communities were described by Automated Ribosomal Intergenic Spacer Analysis and terminal restriction fragment length polymorphism of the gene encoding the major capsid protein (g23) and 18S ribosomal DNA, respectively. Concurrent shifts in community structure suggested similar timing of responses to environmental and biological parameters. We linked T4-like myoviral, bacterial and protistan operational taxonomic units by local similarity correlations, which were then visualized as association networks. Network links (correlations) potentially represent synergistic and antagonistic relationships such as viral lysis, grazing, competition or other interactions. We found that virus–bacteria relationships were more cross-linked than protist–bacteria relationships, suggestive of increased taxonomic specificity in virus–bacteria relationships. We also found that 80% of bacterial–protist and 74% of bacterial–viral correlations were positive, with the latter suggesting that at monthly and seasonal timescales, viruses may be following their hosts more often than controlling host abundance.
Movement patterns of Tenebrio beetles demonstrate empirically that correlated-random-walks have similitude with a Lévy walk
Authors: Reynolds Andy M. , Leprêtre Lisa , Bohan David A. 
Published: November 2013

AbstractCorrelated random walks are the dominant conceptual framework for modelling and interpreting organism movement patterns. Recent years have witnessed a stream of high profile publications reporting that many organisms perform Lévy walks; movement patterns that seemingly stand apart from the correlated random walk paradigm because they are discrete and scale-free rather than continuous and scale-finite. Our new study of the movement patterns of Tenebriomolitor beetles in unchanging, featureless arenas provides the first empirical support for a remarkable and deep theoretical synthesis that unites correlated random walks and Lévy walks. It demonstrates that the two models are complementary rather than competing descriptions of movement pattern data and shows that correlated random walks are a part of the Lévy walk family. It follows from this that vast numbers of Lévy walkers could be hiding in plain sight.
Substrate integrated waveguide filter with embedded mixed source–load coupling
Authors: Xu Z.Q. , Wang P. , Qian K.W. , Tian Z. 
Published: November 2013

A compact substrate integrated waveguide (SIW) filter with an improved stopband using multilayer embedded mixed coupling (MC) is presented. By implementing MC into the input/output SIW, the filter not only exhibits good rejection for the upper stopband, owing to an additional controllable transmission zero, but also has a miniature size of 18 × 12 mm2 by profiting from its low‐temperature co‐fired ceramic structure. An experimental second‐order filter with three TZs has been designed and fabricated. The measured results show good agreement with the simulated ones.
Combined three monopoles for GPS/WLAN/GSM/WCDMA/LTE application
Authors: Jeong S. , Ren Y.‐J. , Warden J. , Lee C.S. 
Published: November 2013

A novel compact antenna is designed on a low‐loss ceramic material to support multiband operation as well as to reduce the antenna size. Three monopole antennas with a single feed are designed and combined for wireless device applications, occupying only 10 × 10 × 3 mm3. Structurally, orthogonal placement of the three monopoles provides a relatively simple design process. Across the entire bands of interest, it is shown that more than 50% of the incident energy radiates into free space. Detailed analysis and measurement results are presented.
Metal mount RFID tag antenna excited by integrated loop/IC module
Authors: Quiroz R. , Laheurte J.‐M. 
Published: November 2013

A simple topology is described for radio frequency identification (RFID) tags mountable on metal surfaces. The tag is built around a commercial UHF RFID module combining an IC and a coupling loop. The module is placed in the neighbourhood of a slot which is used both to couple the energy from the module to the patch‐like antenna and to miniaturise the tag. A read range of almost 4 m is obtained in the 865–868 MHz band with a 1.6 mm low‐cost FR4 substrate.
Design of comb reflection frequency selective surface for interference reduction in corridors of buildings
Authors: Davenport C.J. , Rigelsford J.M. 
Published: November 2013

A periodic comb reflection frequency selective surface (CR‐FSS) is presented for reducing interference caused by the propagation of signals via corridors. The novel CR‐FSS has been designed to reduce the power of the forward scattered signal and increase the backscatter. For a specified comb period and angle of incidence, the direct forward scatter of the CR‐FSS can be reduced by 5–15 dB and the backscatter increased by 10–15 dB over a frequency range of 10.8–13.5 GHz for a vertically polarised signal and 10.8–17 GHz for the horizontal polarisation. The CR‐FSS is thus shown to be effective for both vertically and horizontally polarised signals. Comb period and angle of incidence are chosen to satisfy the conditions of Bragg's Law to provide a maximum backscatter at 10.8 GHz. By installing this novel surface in corridors, interference between multiple neighbouring transmitters can be reduced.
Selective harmonic elimination in multi‐level inverter with zig‐zag connection transformers
Authors: Young Chung‐Ming , Wu Sheng‐Feng 
Published: November 2013

This study applies the selective harmonic elimination (SHE) technique to determine the switching angles for a multi‐level inverter that cooperated with specially connected transformers. With the ability of directly controlling harmonics, the SHE technique has the adaptability to associate with apparatus which are congenitally immune to specific harmonics, such as the zig‐zag connection transformers. In this study, the two sets of primary windings of the transformers are supplied by two six‐switch full‐bridge inverters with 30 electrical degrees phase shift. Harmonics with orders other than 12h ± 1 (h is positive integral) will not appear in the output voltages in the secondary side of the transformer because they are prohibited by the transformers. Then, the SHE technique with half‐wave symmetry is employed to eliminate some selected harmonics with orders equal to 12h ± 1, and adjusts the amplitude of the fundamental. This study obtains a set of precise switching angles through offline calculation over a wide range of modulation indices. A digital signal processor is used to implement online calculation of the switching angles by an approximate method derived from the precise solutions. Some selected analysis and experimental results are demonstrated in this paper. A 4 kW prototype is built to verify the validity of the proposed system.

Published: November 2013

Abstract

Background:
Although the use of an anesthesiology “airway” rotation to train the nonanesthesiologist is commonly employed, little data exist on the utility, clinical exposure, and outcomes of these programs.

Methods:
A prospectively collected observational dataset of airway procedures completed by trainees in a 4-week, anesthesiology-based, airway rotation at an academic, level-1 trauma center from July 2010 to September 2012 was reviewed. Prospectively defined data points were collected through an online data tool and included patient demographics, location, date, best laryngoscopic view, and attempt details. At the authors’ institution, an attending trauma anesthesiologist is present for all intubation attempts. The primary outcome was first-attempt success.

Results:
A total of 4,282 self-reported, airway procedures were identified. The median number of procedures performed was 50.4 ± 13.2 (range, 20 to 93; 25th quartile = 41; 75th quartile = 57). Multivariate logistic regression analysis modeling of first-attempt success rate identified two independent predictors of success: rotation week (odds ratio, 1.42; 95% CI, 1.32 to 1.61; P < 0.0001) and number of previous intubation attempts before rotation (odds ratio, 1.23; 95% CI, 1.03 to 1.46; P = 0.02. In addition, the percentage of cases with a self-reported laryngoscopic grade 1 view increased significantly from 61 to 74% (P = 0.015) from week 1 to week 4 of the rotation.

Conclusions:
An anesthesiology-based program for airway training of nonanesthesiologists demonstrates improved self-reported, perceived first-attempt success over the course of training with improved ability to visualize glottic structures.
The interaction between environment and strategic orientation in born globals’ choice of entry mode
Authors: Efrat Kalanit , Shoham Aviv 
Published: November 2013

Purpose
– Entry modes are a central aspect of international business, particularly for young firms lacking organizational experience and capital, such as born global (BG) firms. Few studies on BG internationalization have addressed the antecedents to entry mode decisions in BG firms. Based on the two main groups of factors impacting entry mode decisions in general, namely environmental (external) conditions and firms’ strategic characteristics, the purpose of this paper is to explore how the interaction between country and market factors and BGs’ strategic orientation affects BGs’ choice of low- vs high-commitment entry modes.

Design/methodology/approach
– Data from 104 Israeli high-tech BG firms were gathered in field interviews with managers. Preliminary analyses assessed non-response bias.

Findings
– Most BGs showed a strong Prospector orientation manifested by exploration and exploitation of opportunities. This in turn moderated the impact of several host market factors on the choice of entry mode, encouraging BGs to choose high-commitment entry modes.

Practical implications
– Contrary to earlier research claiming that BGs minimize risk by choosing low-commitment entry modes, the findings show that BGs’ choice of commitment level is affected by host market characteristics.

Originality/value
– It is often thought that BGs’ choice of entry mode is decisively affected by the host market risk profile, encouraging the choice of low-commitment entry modes in riskier markets. As the findings show, however, BGs are also sensitive to the opportunities provided by the host market, sometimes resulting in high-commitment entry modes.
Co-producing care services in rural areas
Authors: Munoz Sarah-Anne 
Published: November 2013

Purpose– Current policy context in the UK promotes the “co-production” of health and care services – with service users and providers working in partnership. However, the assumption that all individuals and communities have the personal resources, skills and willingness to get involved in co-produced services may have implications for social and geographical equity of access to health and care services. The paper presents the results of a nine-month action research project with a remote and rural community in Scotland to discuss the implications of co-produced health and care services for remote and rural community members – particularly those with ageing populations.Design/methodology/approach– The research project worked with community members, health care providers and commissioners to develop a community social enterprise model for home care delivery. Textual resources collected during this action research process were subject to thematic analysis in order to explore community perceptions and experiences of service co-production development in the remote and rural context.Findings– The qualitative analysis showed that community members identified some positive aspects of being involved in service co-production relating to sense of community, empowerment and personal satisfaction. However, negative impacts included increased feelings of pressure, strain and frustration among those who took part in the co-production process. Overall, the community was reluctant to engage with “transformative” co-production and traditional provider-user dynamics were maintained.Originality/value– The example is used to demonstrate the types of resources that rural individuals and communities draw on in order to create social enterprises and how the potentially negative impacts of co-produced services for different types of social and geographical community may be overlooked in contemporary policy and practice.
Extreme trust: the new competitive advantage
Authors: Peppers Don , Rogers Martha 
Published: November 2013

Purpose
– The authors posit that leading companies are achieving competitive advantage by designing their information system and operations to protect and promote each customer's interest proactively.

Design/methodology/approach
– Called “extreme trust,” this approach requires a re-assessment of value produced by the systems that produce the customer journey experience.

Findings
– Companies need to revisit customer relationship management in the light of three principles: Seeing opportunities to create value from the perspective of the customer; taking extra steps when necessary to ensure that a customer does not make a mistake, or overlook some benefit or service; and not failing to do something that would have significant benefit for the customer.

Research limitations/implications
– Case examples are offered.

Practical implications
– Trustability is in fact financially attractive for a business, even though in many situations it may cost money up front in the form of forgone profits or newly incurred expenses, as many business improvements do.

Originality/value
– The authors promote the proposition that quantifying the benefits of establishing “extreme trust” – including the value of increased customer loyalty, referrals and additional sales – requires a robust customer analytics capability, as well as a financial perspective that fairly balances short-term and long-term results.
Implementation of mindfulness training for adolescent residential clients
Authors: Orlando Edelen Maria , L. Cerully Jennifer , A. Verni Ken , S. Tucker Joan , Fox Eriach 
Published: November 2013

Purpose
– Interest in using mindfulness as a clinical intervention technique has increased, with evidence suggesting that it can be successfully integrated both into treatment for adolescents and for people with substance use disorders. The purpose of this paper is to explore the degree to which mindfulness training can be implemented among adolescents undergoing residential substance abuse treatment.

Design/methodology/approach
– Nine adolescent males in a residential therapeutic community (TC) substance use treatment center enrolled in a voluntary mindfulness training program consisting of eight 90 minute sessions, each led by a clinical psychologist trained in mindfulness-based stress reduction. After the training program concluded, a brief participant survey and participant and staff focus groups were conducted.

Findings
– Both survey and focus group discussions indicate that the mindfulness training program was perceived as helpful, acceptable, and feasible. Suggestions for integrating mindfulness training into residential treatment facilities for adolescents are discussed.

Originality/value
– This study highlights the potential of mindfulness training to augment traditional TC treatment for adolescents, and provides enough information for practitioners to implement mindfulness training in their treatment settings.
Antibiotic‐induced Cardiac Arrhythmias
Authors: Abo‐Salem Elsayed , Fowler John C. , Attari Mehran , Cox Craig D. , Perez‐Verdia Alejandro , Panikkath Ragesh , Nugent Kenneth 
Published: November 2013

SummaryThis review aims to clarify the underlying risk of arrhythmia associated with the use of macrolides and fluoroquinolones antibiotics. Torsades de pointes (TdP) is a rare potential side effect of fluoroquinolones and macrolide antibiotics. However, the widespread use of these antibiotics compounds the problem. These antibiotics prolong the phase 3 of the action potential and cause early after depolarization and dispersion of repolarization that precipitate TdP. The potency of these drugs, as potassium channel blockers, is very low, and differences between them are minimal. Underlying impaired cardiac repolarization is a prerequisite for arrhythmia induction. Impaired cardiac repolarization can be congenital in the young or acquired in adults. The most important risk factors are a prolonged baseline QTc interval or a combination with class III antiarrhythmic drugs. Modifiable risk factors, including hypokalemia, hypomagnesemia, drug interactions, and bradycardia, should be corrected. In the absence of a major risk factor, the incidence of TdP is very low. The use of these drugs in the appropriate settings of infection should not be altered because of the rare risk of TdP, except among cases with high‐risk factors.
Identification of mutant genes with high‐frequency, high‐risk, and high‐expression in lung adenocarcinoma

Published: November 2013

AbstractBackgroundTo identify mutant genes with high‐frequency‐risk‐expression between lung adenocarcinoma and normal samples.MethodsThe ribonucleic acid RNA‐Seq data GSE34914 and GSE37765 were downloaded from the Gene Expression Omnibus database, including 12 lung adenocarcinoma samples and six controls. All RNA‐Seq reads were processed and the gene‐expression level was calculated. Single nucleotide variation (SNV) was analyzed and the locations of mutant sites were recorded. In addition, the frequency and risk‐level of mutant genes were calculated. Gene Ontology (GO) functional analysis was performed. The reported cancer genes were searched in tumor suppressor genes, Cancer Genes, and the Catalogue of Somatic Mutations in Cancer (COSMIC) database.ResultsThe SNV annotations of somatic mutation sites showed that 70% of mutation sites in the exon region occurred in the coding sequence (CDS). Thyroid hormone receptor interactor (TRIP)12 was identified with the highest frequency. A total of 118 mutant genes with high frequency and high‐risk were selected and significantly enriched into several GO terms. No base mutation of cyclin C (CCNC) or RAB11A was recorded. At fragments per kilobase per million reads (FPKM) ≥ 56.5, reported tumor suppressor genes catenin (cadherin‐associated protein), delta (CTNND)1, dual specificity phosphatase (DUSP)6, malate dehydrogenase (MDH)1 and RNA binding motif protein (RBM)5, were identified. Notably, signal transducer and activator of transcription 2 (STAT2) was the only transcription factor (TF) with high‐risk mutation and its expression was detected.ConclusionFor the mutant genes with high‐frequency‐risk‐expression, CTNND1, DUSP6, MDH1 and RBM5 were identified. TRIP12 might be a potential cancer‐related gene, and expression of TF STAT2 with high‐risk was detected. These mutant gene candidates might promote the development of lung adenocarcinoma and provide new diagnostic potential targets for treatment.
Opinions on the counselling, care and outcome of extremely premature birth among healthcare professionals in Finland
Authors: Taittonen L , Korhonen PH , Palomäki O , Luukkaala T , Tammela O 
Published: November 2013

AbstractAimTo study the opinions of paediatric and obstetric personnel on the perinatal treatment and delivery outcome of infants from 22+0 to 27+6 weeks' gestation.MethodsAn email questionnaire was sent to 2963 professionals in 32 maternity hospitals in Finland.ResultsThe questionnaire survey was completed by 856 (28%) professionals in 30 hospitals. Opinions on outcome were most pessimistic if the infant was very premature. More than a third (37%) assumed no survival at the earliest gestational age, but none dismissed the possibility at 26 weeks' gestation. Paediatric professionals took a more active approach to the treatment of a premature birth and baby than obstetric personnel. Opinions on treatment activity were based firstly on what was best for the baby and secondly on experience. Gynaecologists reported discussing matters regarding premature birth with the parents more often than paediatricians and were much more likely to be influenced by these discussions.ConclusionPaediatric personnel showed a more positive attitude and a more active approach to extremely premature deliveries and babies than obstetric personnel. There would appear to be some inconsistency between prenatal counselling and treatment activity after birth at the limit of viability.
Examining workload models in online and blended teaching
Authors: Tynan Belinda , Ryan Yoni , Lamont‐Mills Andrea 
Published: November 2013

AbstractOver the past decade, most Australian universities have moved increasingly towards “blended” and online course delivery for both undergraduate and graduate programs. In almost all cases, elements of online teaching are part of routine teaching loads. Yet detailed and accurate workload data associated with “e‐teaching” are not readily available. A search of the international literature indicated that there is limited rigorous literature and research that points to the actual effects on workload in online and blended higher education teaching environments. This paper reports on a research project in four Australian universities, and the perceptions of a representative group of staff who perceived that e‐teaching had increased their “teaching time” workload, and that Workload Allocation Models (WAMs) did not take account of contemporary teaching modalities.
Subjective well‐being in dentists: the role of intrinsic aspirations
Authors: Montasem Alexander , Brown Stephen L. , Harris Rebecca 
Published: November 2013

AbstractObjectivesTo take a motivational approach, testing an idea derived from self‐determination theory (SDT) that the pursuit of intrinsic life and professional aspirations is associated with enhanced subjective well‐being.MethodsA cross‐sectional survey of a cluster sample of 583 dentists in England provided data on the subjective importance of their intrinsic and extrinsic aspirations and their perceived likelihood of achieving those aspirations. The dependent variable was a four‐domain measure of subjective well‐being.ResultsControlling measures of core self‐evaluations and trait emotional intelligence, the perceived importance and likelihood of achieving intrinsic aspirations were uniquely related to positive affect; the perceived likelihood of achieving intrinsic aspirations was uniquely related to job and life satisfaction and positive affect, and the perceived likelihood of achieving extrinsic aspirations was uniquely related to life satisfaction. No aspiration variables uniquely predicted negative affect.ConclusionsThese findings lend support to self‐determination theory and provide a platform for the future development of interventions that can promote and maintain well‐being in dentists.
