Mavenism and e-maven propensity: antecedents, mediators and transferability
Authors: Darley William , Lim Jeen-Su 
Published: September 2018

Purpose
Using social cognitive theory as a theoretical backdrop, this paper aims to investigate antecedents and mediators of e-maven propensity and evaluates the transferability of physical market maven to online channel. A conceptual model capturing the links among information seeking tendency, physical market maven, e-shopping attitude and e-satisfaction as determinants of e-maven propensity is developed and tested.

Design/methodology/approach
Survey data from 199 adult consumers were collected and analyzed using structural equation modeling with multi-group analysis.

Findings
The results show the direct and indirect effects of physical market maven on e-maven propensity. Additionally, the relationship between physical market maven and e-maven propensity is moderated by e-shopping intensity such that the relationship is stronger for the high e-shopping intensity group than for the low e-shopping intensity group.

Practical implications
In a multi-channel environment, being able to share marketplace information across different channels takes on greater significance. Developing a customized strategy in managing e-word-of-mouth and e-maven behaviors within the context of the level of consumers’ e-shopping intensity is needed. E-mavens could be invited not only to serve as co-creators but also as significant influencers for a company’s products and services.

Originality/value
The study draws an interesting parallel between physical mavens and their online characteristics, as well as captures the conditions under which transferability of physical maven behavior to online channel occurs. Two distinct patterns are exhibited depending on the level of e-shopping intensity.

Published: September 2018

Purpose
There has been a growing concern about air quality because in recent years, industrial and vehicle emissions have resulted in unsatisfactory human health conditions. There is an urgent need for the measurements and estimations of particulate pollutants levels, especially in urban areas. As a contribution to this issue, the purpose of this paper is to use data from measured concentrations of particulate matter and meteorological conditions for the predictions of PM10.

Design/methodology/approach
The procedure included daily data collection of current PM10 concentrations for the city of São Carlos-SP, Brazil. These data series enabled to use an estimator based on artificial neural networks. Data sets were collected using the high-volume sampler equipment (VFA-MP10) in the period ranging from 1997 to 2006 and from 2014 to 2015. The predictive models were created using statistics from meteorological data. The models were developed using two neural network architectures, namely, perceptron multilayer (MLP) and non-linear autoregressive exogenous (NARX) inputs network.

Findings
It was observed that, over time, there was a decrease in the PM10 concentration rates. This is due to the implementation of more strict environmental laws and the development of less polluting technologies. The model NARX that used as input layer the climatic variables and the PM10 of the previous day presented the highest average absolute error. However, the NARX model presented the fastest convergence compared with the MLP network.

Originality/value
The presentation of a given PM10 concentration of the previous day improved the performance of the predictive models. This paper brings contributions with the NARX model applications.
Brand orientation and brand performance in SMEs
Authors: Odoom Raphael , Mensah Priscilla 
Published: September 2018

Purpose
This study aims to investigate the moderating effects of innovation capabilities and social media capabilities on the relationship between brand orientation and brand performance among small- and medium-sized enterprises (SMEs). Drawing on the size differential feature from the organizational ecology theory, the paper further tests variations in these conditions across disaggregated SME levels.

Design/methodology/approach
The empirical part of the study was carried out with a sample of 484 enterprises in an emerging market context via exploratory and confirmatory factor analyses, along with a moderated hierarchical regression.

Findings
Results from the moderated hierarchical regression analysis indicate that although the two capabilities generally offered positive moderating effects across all enterprises, these are conditional and not invariant when disaggregated based on enterprise sizes (small vs medium).

Originality/value
The study suggests the need for enterprise owners/managers to identify optimal combinations of enterprise capabilities, based on their sizes, for which their complementarities with brand orientation efforts are more potent.
Workaround behaviour in information systems research
Authors: de Vargas Pinto Aline , Maçada Antônio Carlos Gastaud , Mallmann Gabriela Labres 
Published: September 2018

Purpose
The purpose of this paper is to provide an analysis of the studies about workaround behavior in the Information Systems (IS) area, addressing its positive and negative aspects and raising the key related issues.

Design/methodology/approach
A systematic literature review was conducted to verify how workaround behavior has been approached in IS studies. A qualitative method was adopted and implemented in two stages: selection of articles from the time period 2007-2017 in the databases Web of Science, ScienceDirect and Scopus and analysis of the selected articles.

Findings
The results showed that many studies have been concerned with identifying the principal reasons for the manifestation of workaround behavior and the measures taken to reduce its impacts. Many studies from international journals examined the implementation of an ERP along with the workaround behavior. The need to expand the national studies on workaround behavior is emphasized, because the majority of the identified studies are international.

Research limitations/implications
The key limitation is related to the period of analysis, because only articles published since 2007 were selected.

Practical implications
This paper contributes to both theory and practice, bringing relevant concepts about workaround behavior, and corroborating the importance of the studies on workaround in the IS area. The literature review of the 20 articles analyzed reveals the main features in each article, such as theoretical and methodological aspects that support the research. Based on this analysis, a conceptual map was developed presenting the most relevant points about workaround behavior, where the causes, the negative and positive consequences, the types of solutions and the organizational and individual impacts are presented.

Originality/value
Research into workaround behavior has increased in recent years, however very few studies have been conducted in Brazil. To the best of the authors' knowledge, no articles regarding Brazil and this subject were published between 2007 and 2017. Thus, this paper seeks to redress this imbalance.
IL‐4 dysregulates microRNAs involved in inflammation, angiogenesis and apoptosis in epidermal keratinocytes
Authors: Bao Lei , Chau Cecilia , Bao Jeremy , Tsoukas Maria M. , Chan Lawrence S. 
Published: September 2018

ABSTRACTIL‐4 plays an important role in the pathogenesis of atopic dermatitis (AD) by dysregulating many key factors at the transcriptional level. In this study, a microRNA array technique and IL‐4 transgenic mice were used to demonstrate that IL‐4 dysregulates microRNAs involved in inflammation, angiogenesis, lymphangiogenesis and apoptosis. Of the 372 common microRNAs examined, 26 and one microRNAs were found to be up‐ and down‐regulated, respectively. MicroRNA‐101‐5p, −122‐5p, −142‐3p, −204‐5p, −335‐3p, −376a‐3p, −378a‐5p, −639 and −9‐5p are among the most significantly up‐regulated microRNAs. MicroRNA‐147a, the only one that was down‐ regulated in the present study, attenuates TLR‐induced inflammatory responses. These dysregulated microRNAs may provide post‐transcriptional regulation of key genes in AD.

SummaryMarine microscopic algae carry out about half of the global carbon dioxide fixation into organic matter. They provide organic substrates for marine microbes such as members of the Bacteroidetes that degrade algal polysaccharides using carbohydrate‐active enzymes (CAZymes). In Bacteroidetes genomes CAZyme encoding genes are mostly grouped in distinct regions termed polysaccharide utilization loci (PULs). While some studies have shown involvement of PULs in the degradation of algal polysaccharides, the specific substrates are for the most part still unknown. We investigated four marine Bacteroidetes isolated from the southern North Sea that harbour putative mannan‐specific PULs. These PULs are similarly organized as PULs in human gut Bacteroides that digest α‐ and β‐mannans from yeasts and plants respectively. Using proteomics and defined growth experiments with polysaccharides as sole carbon sources we could show that the investigated marine Bacteroidetes express the predicted functional proteins required for α‐ and β‐mannan degradation. Our data suggest that algal mannans play an as yet unknown important role in the marine carbon cycle, and that biochemical principles established for gut or terrestrial microbes also apply to marine bacteria, even though their PULs are evolutionarily distant.

SummaryWhite‐rot fungi, such as Dichomitus squalens, degrade all wood components and inhabit mixed‐wood forests containing both soft‐ and hardwood species. In this study, we evaluated how D. squalens responded to the compositional differences in softwood [guaiacyl (G) lignin and higher mannan content] and hardwood [syringyl/guaiacyl (S/G) lignin and higher xylan content] using semi‐natural solid cultures. Spruce (softwood) and birch (hardwood) sticks were degraded by D. squalens as measured by oxidation of the lignins using 2D‐NMR. The fungal response as measured by transcriptomics, proteomics and enzyme activities showed a partial tailoring to wood composition. Mannanolytic transcripts and proteins were more abundant in spruce cultures, while a proportionally higher xylanolytic activity was detected in birch cultures. Both wood types induced manganese peroxidases to a much higher level than laccases, but higher transcript and protein levels of the manganese peroxidases were observed on the G‐lignin rich spruce. Overall, the molecular responses demonstrated a stronger adaptation to the spruce rather than birch composition, possibly because D. squalens is mainly found degrading softwoods in nature, which supports the ability of the solid wood cultures to reflect the natural environment.

Published: September 2018

SummaryDimethylsulfide (DMS), a dominant organic sulfur species in the surface ocean, may act as a signalling molecule and contribute to mutualistic interactions between bacteria and marine algae. These proposed functions depend on the DMS concentration in the vicinity of microorganisms. Here, we modelled the DMS enrichment at the surface of DMS‐releasing marine algal cells as a function of DMS production rate, algal cell radius and turbulence. Our results show that the DMS concentration at the surface of unstressed phytoplankton with low DMS production rates can be enriched by <1 nM, whereas for mechanically stressed algae with high activities of the enzyme DMSP‐lyase (a coccolithophore and a dinoflagellate) DMS cell surface enrichments can reach ~10 nM, and could potentially reach μM levels in large cells. These DMS enrichments are much higher than the median DMS concentration in the surface ocean (1.9 nM), and thus may attract and support the growth of bacteria living in the phycosphere. The bacteria in turn may provide photoactive iron chelators (siderophores) that enhance algal iron uptake and provide algal growth factors such as auxins and vitamins. The present study highlights new insights on the extent and impact of microscale DMS enrichments at algal surfaces, thereby contributing to our understanding of the potential chemoattractant and mutualistic roles of DMS in marine microorganisms.
Isotope discrimination by form IC RubisCO from Ralstonia eutropha and Rhodobacter sphaeroides, metabolically versatile members of ‘Proteobacteria’ from aquatic and soil habitats

SummaryRubisCO, the CO2 fixing enzyme of the Calvin–Benson–Bassham (CBB) cycle, is responsible for the majority of carbon fixation on Earth. RubisCO fixes 12CO2 faster than 13CO2 resulting in 13C‐depleted biomass, enabling the use of δ13C values to trace CBB activity in contemporary and ancient environments. Enzymatic fractionation is expressed as an ε value, and is routinely used in modelling, for example, the global carbon cycle and climate change, and for interpreting trophic interactions. Although values for spinach RubisCO (ε = ~29‰) have routinely been used in such efforts, there are five different forms of RubisCO utilized by diverse photolithoautotrophs and chemolithoautotrophs and ε values, now known for four forms (IA, B, D and II), vary substantially with ε = 11‰ to 27‰. Given the importance of ε values in δ13C evaluation, we measured enzymatic fractionation of the fifth form, form IC RubisCO, which is found widely in aquatic and terrestrial environments. Values were determined for two model organisms, the ‘Proteobacteria’ Ralstonia eutropha (ε = 19.0‰) and Rhodobacter sphaeroides (ε = 22.4‰). It is apparent from these measurements that all RubisCO forms measured to date discriminate less than commonly assumed based on spinach, and that enzyme ε values must be considered when interpreting and modelling variability of δ13C values in nature.

Published: September 2018

ObjectiveTo estimate the causal effects of a population‐scale behavioral weight management program and to determine whether the program's effectiveness depends on participants’ geographic access to places to purchase healthy and less healthy foods.Data SourcesSecondary data from U.S. Department of Veterans Affairs clinical and administrative records (2008–2014), retail food environment measures from commercial databases (2008–2014), and the American Community Survey (2009–2014).Study DesignWe estimated the effect of the VA's MOVE! weight management program on body mass index after 6 months using difference‐in‐difference regressions to compare participants with a propensity score‐matched control group. We estimated treatment effects overall and in subgroups with different access to supermarkets, fast‐food restaurants, and convenience stores.Principal FindingsMOVE! reduced BMI by about 0.71 units among men and 0.70 units among women. The program was slightly less effective for men living near fast‐food restaurants or convenience stores. We found no evidence that treatment effects varied with the food environment among women.ConclusionsThe residential food environment modestly alters MOVE! effectiveness among men. A greater understanding of environmental barriers to and facilitators of intentional weight loss is needed. This study highlights important potential intersections between health care and the community.

ObjectiveTo estimate health care utilization and costs incurred by homeless Veterans relative to nonhomeless Veterans and to examine the impact of a VA homelessness program on these outcomes.Data Sources/Study SettingCombined Department of Veterans Affairs (VA) administrative and Medicare claims data.Study DesignObservational study using longitudinal data from Veterans engaged with the VA system and enrolled in Medicare. Veterans with administrative evidence of homelessness at any point during 2006–2010 were matched on period of military service to Veterans with no evidence of homelessness.Principal FindingsExperience of homelessness was associated with 1.37 (95 percent CI = 1.34–1.40) and 0.16 (95 percent CI = 0.14–0.17) more outpatient encounters per quarter in VA and non‐VA settings, respectively, and 1.31 (95 percent CI = 1.30–1.32) and 0.49 (95 percent CI = 0.48–0.49) more inpatient days per quarter in VA and non‐VA hospitals, respectively. These were associated with higher costs. Relative to stably housed Veterans less than 65 years of age, those enrolled in a VA homelessness program had 94.4 percent (95 percent CI = 90.7 percent–98.1 percent) more VA outpatient visits but 5.5 percent (95 percent CI = 3.0 percent–7.9 percent) fewer Medicare outpatient visits.ConclusionsHomelessness was associated with an increase in VA and Medicare utilization and cost. A VA homelessness program decreased use of Medicare outpatient services.
A Forensic Entomological Analysis Can Yield an Estimate of Postmortem Interval, and Not Just a Minimum Postmortem Interval: An Explanation and Illustration Using a Case
Authors: Wells Jeffrey D. 
Published: September 2018

AbstractSeveral authors claimed that a forensic entomological analysis can never be interpreted as the postmortem interval (PMI), but that it can be interpreted as a minimum postmortem interval (PMImin), or dead for not less than X amount of time. Because in most instances, a PMI estimate should be a range, that is, the set of values from maximum postmortem interval (PMImax) to PMImin, objections to PMI estimation are objections to PMImax estimation. The arguments for this position did not address the substantial body of literature describing estimation of both PMImax and PMImin using insect succession analysis. This report reviews the scientific issues and presents a recent homicide investigation in which several forensic entomology experts used the absence of carrion insects on the corpse, a kind of succession analysis, to estimate PMI or PMImax.

Published: September 2018

SummaryNeurofibromatosis type 1 (NF1) is a multisystem phakomatosis. The intrathoracic manifestations of NF1 are protean. We describe a rare case of a plexiform neurofibroma infiltrating the mediastinum and lungs with multiple endobronchial neurofibromata. To our knowledge, a mediastinal plexiform neurofibroma extending into the lungs on CT has not been reported.
CLEARED (Chemicals and Litmus testing with Effective Alkaline Range for Eye Damage): A Prospective, Interventional Study

Published: September 2018

AbstractObjectivesWhile immediate diagnosis and irrigation is standard chemical eye burn practice, it is unknown to what extent specific pH measurements influence management, given the frequent clinical availability of narrow‐spectrum nitrazine pH strips. We hypothesize that exclusive broad‐spectrum pH strip implementation leads to more accurate measurement and expedited ophthalmologic consultation.MethodsAt a Level I trauma center over 25 months, all emergent adult ophthalmology consultations for chemical burns were included in a pre‐intervention (n = 22) and post‐intervention (n = 20) study design. During this time, narrow‐spectrum nitrazine pH strips available to non‐obstetric emergency department (ED) staff were exclusively replaced by broad‐spectrum strips. Causative chemical, time from triage to ophthalmology consultation, examination findings, ocular pH by ED and ophthalmology staff, and irrigation quantity were analyzed.ResultsMost burns were alkaline. Time from triage (p = 0.043) and irrigation quantity following consultation (p = 0.047) each decreased following exclusive ED implementation of broad‐spectrum pH strips. There was greater pH congruence between consulting and primary physicians after intervention (p = 0.03).ConclusionsExclusive non‐obstetric implementation of broad‐spectrum pH strips may allow greater accuracy and faster management of ocular chemical burns. Availability of narrow‐spectrum pH strips may be dangerous clinically by falsely reassuring the examiner with inherent inaccuracy.

AbstractAimsSurvey data from 10 diverse countries were used to analyse the social location of harms from others’ drinking: which segments of the population are more likely to be adversely affected by such harm, and how does this differ between societies?MethodsGeneral‐population surveys in Australia, Chile, India, Laos, New Zealand, Nigeria, Sri Lanka, Thailand, United States and Vietnam, with a primary focus on the social location of the harmed person by gender, age groups, rural/urban residence and drinking status. Harms from known drinkers were analysed separately from harms from strangers.ResultsIn all sites, risky or moderate drinkers were more likely than abstainers to report harm from the drinking of known drinkers, with risky drinkers the most likely to report harm. This was also generally true for harm from strangers’ drinking, although the patterns were more mixed in Vietnam and Thailand. Harm from strangers’ drinking was more often reported by males, while gender disparity in harm from known drinkers varied between sites. Younger adults were more likely to experience harm both from known drinkers and from strangers in some, but not all, societies. Only a few sites showed significant urban/rural differences, with disparities varying in direction. In multivariate analyses, most relationships remained, although some were no longer significant.ConclusionThe social location of harms from others’ drinking, whether known or a stranger, varies considerably between societies. One near‐commonality among the societies is that those who are themselves risky drinkers are more likely to suffer harm from others’ drinking.
