Published: July 2014

AbstractObjectivesLittle is known about the contribution of telephone‐based prescribing on overall antibiotic utilization. The objective of this study was to determine the extent and characteristics of telephone‐based antibiotic prescribing in teaching and non‐teaching primary care practices.MethodsThis retrospective cohort study included all patients (n = 114 610) cared for by teaching and non‐teaching internal medicine, pediatrics, family practice, and obstetrics/gynecology practices (n = 19) affiliated with a large US healthcare system during 2006–2010 and using a common electronic medical record. Rates and types of antibiotics prescribed by teaching and non‐teaching practices via telephone contact and office visit were compared among the overall cohort. All telephone‐related prescriptions during 2008 underwent chart review to determine indications for antibiotic prescribing.ResultsOverall, 28.9 antibiotic prescriptions were issued per 100 patient‐years, with 63 418 total antibiotic prescriptions and 7876 (12.4%) generated after telephone contact. Telephone‐based prescribing increased steadily from 2.2 to 4.2 per 100 patient‐years during the study period. Both telephone‐based and office‐based antibiotic prescribing were higher in non‐teaching practices. Of 1790 antibiotics prescribed by telephone during 2008, the majority were for urinary tract infection (28.3%), sinusitis (20.1%), and unspecified upper respiratory infection (URI, 15.0%).ConclusionsOverall, one in every eight antibiotics was prescribed via telephone encounter. These data highlight the need to include the impact of this practice in analysis of outcomes associated with outpatient antibiotic prescribing and to incorporate telephonic prescribing into guidelines facilitating appropriate antibiotic use.

High‐maturity levels: achieving CMMI ML‐5 in a consultancy company
Authors: Grossi Lucas , Calvo‐Manzano Jose A. , San Feliu Tomas 
Published: July 2014

ABSTRACTMost organizations that use the Capability Maturity Model Integration (CMMI) stop their process improvement journey at Maturity Level 3 or less. The discussion about CMMI high‐maturity levels has always been controversial, going most of the times through the consideration of return of investment, provider selection, and interpretation issues. Achieving Level 5 is not an easy task; it derives a lot of steps during the way. This article will show an example of the implementation of Level 5 in a consultancy company in two constellations: development and service. It depicts the example in steps, to help the understanding of the whole process. Copyright © 2014 John Wiley & Sons, Ltd.
Vers une compréhension nationaliste de la naturalisation au Canada ? Analyse des changements récents en matière d’octroi de la citoyenneté dans le contexte canadien
Authors: Winter Elke , Sauvageau Marie-Michèle 
Published: July 2014

RésuméLe Canada peut se vanter d’avoir un des taux de naturalisation les plus élevés au monde. Dans les derniers cinq ans, une série de modifications aux règles de la citoyenneté ont été instaurées, dont la majorité touche directement le processus de naturalisation. Adoptant une approche sociologique, nous proposons de répondre à la question suivante : La naturalisation au Canada au début du vingt-et-unième siècle, reste-elle aussi « libérale » qu’elle l’était dans les années 1990 ou, au contraire, tourne-t-elle, comme dans beaucoup de pays d’Europe, à la re-nationalisation ? Nos résultats suggèrent qu’il est difficile de conclure à un véritable changement de régime depuis l’arrivée du Parti conservateur au pouvoir, étant donné la portée réelle de la majorité de ces changements. Toutefois, la présence d’un discours de plus en plus identitaire et protecteur face à une façon spécifique d’être Canadien témoigne d’une nouvelle rhétorique autour de la citoyenneté canadienne, rhétorique qui se rapproche d’une conception « nationaliste » de la naturalisation.
Surgical outcomes of malignant sinonasal tumours: open versus endoscopic surgical approaches
Authors: Saedi B , Aghili M , Motiee M , Valadkhani S , Niazi A B , Safavi A 
Published: July 2014

AbstractBackground:Sinonasal malignancies are rare tumours, which can be resected using an open or endoscopic approach. The current study evaluated the outcome of both approaches.Methods:A total of 160 patients with malignant nasal tumours were evaluated in an academic tertiary care hospital. The patients were allocated to ‘open’ or ‘endoscopic’ surgery groups, based on the surgical approach employed. The following data were evaluated and compared: patient and tumour characteristics; oncological treatments; and oncological outcomes, including complications, surgical margin, recurrence, overall survival and disease-free survival.Results:The maxillary sinus was the most common tumour location and squamous cell carcinoma was the most common histopathology-based diagnosis. Younger patients had lower grades of tumour. Higher survival rates were significantly related to lower tumour stages in both surgery groups. There were no differences between the two relatively similar groups in terms of surgical margin, the need for adjunctive therapy, and recurrence and survival rates. In addition, multivariate logistical regression analysis indicated no correlations between the type of surgical approach employed and the rates of recurrence and complications.Conclusion:Endoscopic surgery for sinonasal malignancies is comparable to the conventional open approach in carefully selected patients.
USV attitude estimation: an approach using quaternion in direction cosine matrix
Authors: Onunka Chiemela , Bright Glen , Stopforth Riaan 
Published: July 2014

SUMMARYPositioning and navigation data for unmanned surface vehicles (USVs) are extracted using the Global Positioning System (GPS) and the Inertial Navigation System (INS) integrated with an inertial measurement unit (IMU). The integration of quaternion with direction cosine matrix (DCM) with the aim of obtaining high accuracy with complete system independence has been effectively used to supply position and attitude information for autonomous navigation of marine crafts. A DCM integrated with a quaternion provided an advanced technique for precise USV attitude estimation and position determination using low-cost sensors. This paper presents the implementation of an INS developed by the integration of DCM and quaternion.
The color red distorts time perception for men, but not for women
Authors: Shibasaki Masahiro , Masataka Nobuo 
Published: July 2014

AbstractWe investigated the effect of the color red on time perception using a temporal bisection task with human adults. The results showed that the perceived duration of a red screen was longer than was that of a blue screen. However, the results reflected sex differences; men, but not women, overestimated the duration of the red screen. Additionally, the reaction times to a red screen were faster than those to a blue screen and we found a significant correlation between reaction time and the tendency to overestimate the duration of a red screen. Participants who reacted quickly to a red screen overestimated its duration. These results are discussed within the context of recent studies indicating that the color red exerts certain special psychological effects on human behavior.

Published: July 2014

Bovine pulmonary hypertension, brisket disease, causes significant morbidity and mortality at elevations above 2,000 m. Mean pulmonary arterial pressure (mPAP) is moderately heritable, with inheritance estimated to lie within a few major genes. Invasive mPAP measurement is currently the only tool available to identify cattle at risk of hypoxia‐induced pulmonary hypertension. A genetic test could allow selection of cattle suitable for high altitude without the need for invasive testing. In this study we evaluated three candidate genes (myosin heavy chain 15 [MYH15], NADH dehydrogenase flavoprotein 2, and FK binding protein 1A) for association with mPAP in 166 yearling Angus bulls grazing at 2,182 m. The T allele (rs29016420) of MYH15 was linked to lower mPAP in a dominant manner (CC 47.2 ± 1.6 mmHg [mean ± standard error of the mean]; CT/TT 42.8 ± 0.7 mmHg; P = 0.02). The proportions of cattle with MYH15 CC, CT, and TT genotypes were 55%, 41%, and 4%, respectively. Given the high frequency of the deleterious allele, it is likely that the relative contribution of MYH15 polymorphisms to pulmonary hypertension is small, supporting previous predictions that the disease is polygenic. We evaluated allelic frequency of MYH15 in the Himalayan yak (Bos grunniens), a closely related species adapted to high altitude, and found 100% prevalence of T allele homozygosity. In summary, we identified a polymorphism in MYH15 significantly associated with mPAP. This finding may aid selection of cattle suitable for high altitude and contribute to understanding human hypoxia‐induced pulmonary hypertension.
Basic4Cseq: an R/Bioconductor package for analyzing 4C-seq data
Authors: Walter Carolin , Schuetzmann Daniel , Rosenbauer Frank , Dugas Martin 
Published: July 2014

Abstract
Summary: Basic4Cseq is an R/Bioconductor package for basic filtering, analysis and subsequent near-cis visualization of 4C-seq data. The package processes aligned 4C-seq raw data stored in binary alignment/map (BAM) format and maps the short reads to a corresponding virtual fragment library. Functions are included to create virtual fragment libraries providing chromosome position and further information on 4C-seq fragments (length and uniqueness of the fragment ends, and blindness of a fragment) for any BSGenome package. An optional filter is included for BAM files to remove invalid 4C-seq reads, and further filter functions are offered for 4C-seq fragments. Additionally, basic quality controls based on the read distribution are included. Fragment data in the vicinity of the experiment’s viewpoint are visualized as coverage plot based on a running median approach and a multi-scale contact profile. Wig files or csv files of the fragment data can be exported for further analyses and visualizations of interactions with other programs.
Availability and implementation: Basic4Cseq is implemented in R and available at http://www.bioconductor.org/ . A vignette with detailed descriptions of the functions is included in the package.

Possible proton synchrotron origin of X-ray and gamma-ray emission in large-scale jet of 3C 273
Authors: Kundu Esha , Gupta Nayantara 
Published: July 2014

Abstract
The large-scale jet of quasar 3C 273 has been observed in radio to gamma-ray frequencies. Earlier the X-ray emission from knot A of this jet has been explained with inverse Compton scattering of the cosmic microwave background radiations by the shock accelerated relativistic electrons in the jet. More recently it has been shown that this mechanism overproduces the gamma-ray flux at GeV energy and violates the observational results from Fermi LAT. We have considered the synchrotron emission from a broken power-law spectrum of accelerated protons in the jet to explain the observed X-ray to gamma-ray flux from knot A. The two scenarios discussed in our work are (i) magnetic field is high, synchrotron energy loss time of the protons is shorter than their escape time from the knot region and the age of the jet and (ii) their escape time is shorter than their synchrotron energy loss time and the age of the jet. These scenarios can explain the observed photon spectrum well for moderate values of Doppler factor. The required jet luminosity is high ∼1046 erg s−1 in the first scenario and moderate ∼1045 erg s−1 in the second, which makes the second scenario more favourable.

Practical implications
– The study reveals future directions and trend that the academia should consider.

Originality/value
– Information security is top concern for organizations, and this research analyzed how academia dealt with the topic since 1977. Also, the authors suggest future directions for research suggesting new research streams.
Consumer reaction to price increase: an investigation in gasoline industry
Authors: K. Paswan Audhesh , C. Crawford John , Ngamsiriudom Waros , Nguyen Thuy 
Published: July 2014

Purpose
– The aim of this study is to investigate the impact of increase in price of an essential product (i.e. gasoline) toward the focal product and other seemingly non-related products.

Design/methodology/approach
– A self-administered survey was used to collect data from the drivers at a large metroplex in Southwest USA. Multiple regression and scanning electron microscope procedures were used to analyze and test the proposed hypotheses.

Findings
– When consumers notice the increase in gas prices, they become very anxious. This anxiety is positively associated with average gas bought in gallons and negatively associated with threshold price. Further, this consumer anxiety has the strongest influence on lifestyle changes, followed by automobile technology change and transportation mode change, and has the weakest influence on gasoline brand/type change.

Research limitations/implications
– We focus on only anxiety as a mediator between increase in gas prices and the behavioral outcomes, and collect data from only one location.

Practical implications
– Managers must be cognizant that a price increase in essential goods not only influences the demand for focal products but also for products that may not seem related to the focal products.

Social implications
– Increase in gasoline price will not only affect the demand for gasoline, but also the demand for alternate forms of transportation, fuel efficient vehicles, and other aspects of life.

Originality/value
– This study is the first to look at the role of anxiety as a mediator and looks at the effects of increase in gas prices in a holistic manner.
A cross-product category CBBE study: item response theory perspective
Authors: Wang Luming , Finn Adam 
Published: July 2014

Purpose– The purpose of this study is to propose a new item response theory-based model to facilitate brand equity comparison among brands in different product categories. Brand equity has been defined as the value a brand adds upon a product. This definition provides the theoretical basis for comparing brands across product categories. Researchers have measured brand equity from three major approaches: finance, economics and psychology. Unlike the first two approaches that have developed methods to facilitate cross-product-category brand equity comparison, no methodology has been identified in the psychology approach (consumer-based brand equity, CBBE), and this study will fill this gap.Design/methodology/approach– We used survey method and collected data from both soft drink and car product categories to empirically demonstrate our method.Findings– A new item response theory-based model to facilitate brand equity comparison among brands in different product categories is proposed.Originality/value– Considering consumers are the most widely considered stakeholder group in the existing brand equity literature, the lack of cross-product category research in consumer-based brand equity (CBBE) area constrains the use of CBBE for firms managing multiple brands across product categories. This proposed model is the first one to address this limitation.
Prediction of citizen satisfaction with local government based on perceptions of physical disorder
Authors: Oscar Nigro Héctor , Elizabeth González Císaro Sandra 
Published: July 2014

Purpose– The purpose of this paper is to identify the aspects of service quality that citizens view as most important regarding the improvement of their quality of life within the city where they live, by finding out the intangible variables or factors that most influence citizen satisfaction with the local government. The paper uses a measuring instrument to obtain survey data and build a theoretical and empirical model that operates at the level of the local government.Design/methodology/approach– It involves a construction of a causal theoretical model that follows a series of steps that connect the empirical context (data) with the same theoretical representation (model from reality). This model attempts to explain the relations between the latent variables included in the structural equation model from background knowledge inspired in the evolution of social sciences.Findings– The emergent model discriminates three areas pertaining to quality of services, its relationship with the satisfaction of citizens in local government across local leadership image and expectations.Practical implications– Citizens satisfaction indexes provide not only information about citizen satisfaction and the rate of fidelity and perceived quality but also suggestions about the factors influencing this satisfaction.Originality/value– This article describes the many and varied possible relationships between the various precedents and consequences that influence the conceptualization of citizen satisfaction with the local government. The paradigm used focuses on perceptions of physical disorder rather than on the hierarchical approach of conceptualizing the perception of service quality.
Using university websites to profile accounting academics and their research output
Authors: Samkin Grant , Schneider Annika 
Published: July 2014

Purpose
– The purpose of this paper is to examine the profiles of Australian, New Zealand and South African accounting faculty members. Additionally, the study investigates whether there are any differences in research productivity of the accounting faculty between countries as measured by peer-reviewed academic journal output.

Design/methodology/approach
– This archival study uses details obtained from webpages of Departments of Accounting in the three countries to construct a profile of accounting academics.

Findings
– Significant differences in the profiles of accounting academics were found that can be attributed to the institutional factors that exist in each country. Staffs at the junior lecturer and lecturer levels are more likely to be female, while senior lecturers and professors in all three countries were more likely to be male. While Australia and New Zealand had a similar percentage of staff holding PhD or equivalent academic qualifications, only a small proportion of the South African faculty held PhD or equivalent qualifications. A greater proportion of the South African faculty was professionally qualified compared to their Australian and New Zealand counterparts. New Zealand accounting faculty was more productive than their Australian colleagues, with South African academics being the least productive. Academics holding a doctoral qualification or equivalent were more productive than those that did not.

Research limitations/implications
– The research limitations relate to the use of websites as the primary data source. Incompleteness of information, inconsistencies in the type of information presented and a lack of comparability of information across institutions and countries may have led to some errors and omissions. However, given the relatively large sample size of 2,049 academics, this was not deemed to materially affect the final analysis.

Originality/value
– The paper provides an important contribution to the literature on accounting academics. It is the first of its kind to present a comprehensive “snapshot” of the profiles of accounting academics at the universities in Australia, New Zealand and South Africa.
The Australian accounting academic in the 1950s
Authors: E. Persson Martin , J. Napier Christopher 
Published: July 2014

Purpose– The purpose of this paper is to examine the challenges faced by an Australian accounting academic, R. J. Chambers, in the 1950s, in breaking into the accounting research community, at that time, almost entirely located in the USA and the UK. For academics outside the networks of accounting research publication in these countries, there were significant, but not insurmountable obstacles to conducting and publishing accounting research. We examine how these obstacles could be overcome, using the notion of “trials of strength” to trace the efforts of Chambers in wrestling with intellectual issues arising from post-war inflation, acquiring accounting literature from abroad and publishing his endeavours.Design/methodology/approach– The article uses actor-network theory to provide an analytical structure for a “counter-narrative” history firmly grounded in the archives.Findings– Documents from the R. J. Chambers Archive at the University of Sydney form the empirical basis for a narrative that portrays accounting research as a diverse process driven as much by circumstances – such as geographical location, access to accounting literature and personal connections – as the merits of the intellectual arguments.Research limitations/implications– Although the historical details are specific to the case being studied, the article provides insights into the challenges faced by researchers on the outside of international research networks in achieving recognition and in participating in academic debates.Practical implications– The findings of this article can provide guidance and inspiration to accounting researchers attempting to participate in wider academic communities.Originality/value– The article uses documents from perhaps the most extensive archive relating to an individual accounting academic. It examines the process of academic research in accounting in terms of the material context in which such research takes place, whereas most discussions have focussed on the underlying ideas and concepts, abstracted from the context in which they emerge.
