Wine involvement interaction with dining group dynamics, group composition and consumption behavioural aspects in USA restaurants
Authors: Bruwer Johan , Cohen Justin , Kelley Kathleen 
Published: February 2019

Purpose
The importance of the wine involvement construct in explaining consumers’ wine consumption behaviour is widely acknowledged in the literature, as is the social nature of dining out with others. Yet, there is a paucity of research examining the relationships between how this construct interacts with dining group dynamics and wine consumption behavioural aspects in the restaurant environment. This study aims to investigate these aspects in US restaurants.

Design/methodology/approach
Utilising an online survey that yielded a sample of 513 respondents from across the USA who frequented all the recognised restaurant categories, respondents are segmented into low and high wine involvement categories using a reliable wine involvement scale. The authors examine differences between various dining group dynamics, dining group composition, main choice factors when ordering wine and method of ordering wine in US restaurants.

Findings
The authors find that diners’ level of involvement with wine provides sharp insights into several significant differences between involvement and dining group dynamics, group composition, choice factors when ordering wine and method of ordering wine in restaurants. High involvement diners dine out in larger groups, order more wine, spend more money on wine, are more often the main decision-maker ordering wine for the dining group and use wine menus and wall board displays more often when ordering than low involvement diners. They are also more discerning about the taste of wine, grape variety and wine style in terms of choice factors when ordering.

Practical implications
The nature and dynamics of dining groups are aspects that have profound implications, in various ways, for the restaurant industry. The level of involvement diners have with wine is a strong predictor of various outcomes in terms of dining group behavioural aspects regarding wine. Wine-related restaurant category-specific profile descriptions, such as those developed in this study, can be helpful for restaurants when creating business strategies.

Originality/value
The authors make a substantive contribution by being the first study to examine the relationships between dining group dynamics, dining group composition and behavioural aspects concerning wine consumption and involvement in the restaurant environment. The authors then map this information to derive wine-related profile descriptions for all US restaurant categories.
Reflections on global brands, global consumer culture and globalization
Authors: Samiee Saeed 
Published: February 2019

Purpose
The purpose of this paper is to explore global brands, global consumer culture (GCC) and globalization, and offers a thesis in line with Steenkamp (2019) regarding the world’s continued move toward greater integration.

Design/methodology/approach
The study examines the three concepts articulated by Steenkamp (2019): global brands, GCC and globalization.

Findings
Globalization is often thought of as a necessary condition for the existence of global brands and GCC. However, global brands existed long before the transition toward an increasingly integrated world. Further, global branding is related to the development of GCC as an intermarket segment. The paper also highlights the absence of an operational definition for global brands and the overemphasis on consumer brands as the drivers of much of the research in global branding and GCC.

Originality/value
The paper offers a different perspective on the GCC phenomenon, and identifies new avenues for future research.
How functional and emotional ads drive smartwatch adoption

Published: February 2019

PurposeThe purpose of this paper is to examine advertising strategies’ (functional vs emotional) influence on consumers’ evaluation and adoption of smartwatches by drawing on the elaboration likelihood model and the schema incongruity theory. Moderating effects of consumer characteristics (personal innovativeness and extraversion) on the value assessment and attitude relationship are also tested.Design/methodology/approachThe model was assessed using partial least squares-structural equation modeling with a sample of 999 non-smartwatch users.FindingsResults show that functional ads elicit higher levels of hedonic than functional (usefulness) and ergonomic values (ease of use), whereas emotional ads produce higher levels of functional (usefulness) in comparison to hedonic value (enjoyment). Collectively, functional, ergonomic, hedonic and symbolic values shape consumers’ attitude and their subsequent behavior. In addition, findings demonstrate that extraversion positively moderates the symbolic value–attitude relationship, whereas personal innovativeness negatively moderates the functional value–attitude relationship.Originality/valueSmartwatch sales have floundered despite substantial investments in ad campaigns. This study provides novel insights into managing non-users’ value perceptions of smartwatches with the optimal use of ad strategies. Furthermore, it is also one of the first studies to validate the moderating role of extraversion on the symbolic value–attitude link, thus contributing to the emerging literature on wearable technology.
Influential factors for technology-enhanced learning: professionals’ views
Authors: Schweighofer Patrick , Weitlaner Doris , Ebner Martin , Rothe Hannes 
Published: February 2019

PurposeThe literature includes several studies that define different critical success factors (CSF) which have to be considered to support the implementation of technology-enhanced learning (TEL) approaches. An analysis of such studies revealed that (1) regional differences seem to determine the CSF for TEL approaches, (2) certain CSF are relevant for TEL approaches in general, and (3) professionals in higher education determine which influential factors they consider when implementing TEL approaches. Thus, the question arises: in general, which influential factors do professionals in Austrian and German institutions of higher education actually consider when implementing TEL approaches?Design/methodology/approachThe study is a quantitative research approach based on survey data.FindingsThe results show that certain influential factors seem to be generally important, such as the factors of respecting learning success or motivation. However, the outcome of the study also indicated that different moderating variables like experiences and personal relevance affect the professionals’ choices.Originality/valueThe originality and value are in the approach to identify generally important influential factors for the implementation of TEL approaches in Austrian and German institutions of higher education.
Towards automated pre-ingest workflow for bridging information systems and digital preservation services
Authors: Westerlund Parvaneh , Andersson Ingemar , Päivärinta Tero , Nilsson Jörgen 
Published: February 2019

Purpose
This paper aims to automate pre-ingest workflow for preserving digital content, such as records, through middleware that integrates potentially many information systems with potentially several alternative digital preservation services.

Design/methodology/approach
This design research approach resulted in a design for model- and component-based software for such workflow. A proof-of-concept prototype was implemented and demonstrated in context of a European research project, ForgetIT.

Findings
The study identifies design issues of automated pre-ingest for digital preservation while using middleware as a design choice for this purpose. The resulting model and solution suggest functionalities and interaction patterns based on open interface protocols between the source systems of digital content, middleware and digital preservation services. The resulting workflow automates the tasks of fetching digital objects from the source system with metadata extraction, preservation preparation and transfer to a selected preservation service. The proof-of-concept verified that the suggested model for pre-ingest workflow and the suggested component architecture was technologically implementable. Future research and development needs to include new solutions to support context-aware preservation management with increased support for configuring submission agreements as a basis for dynamic automation of pre-ingest and more automated error handling.

Originality/value
The paper addresses design issues for middleware as a design choice to support automated pre-ingest in digital preservation. The suggested middleware architecture supports many-to-many relationships between the source information systems and digital preservation services through open interface protocols, thus enabling dynamic digital preservation solutions for records management.
The role of delayed water curing in improving the mechanical and microstructural properties of alkali activated fly ash based geopolymer paste blended with slag
Authors: Dutta Debabrata , Ghosh Somnath 
Published: February 2019

Purpose
This paper aims to investigate the effect of delayed water curing on the mechanical and microstructural properties of fly ash-based geopolymer paste-blended with Ground Granulated Blast Furnace Slag (GGBS) with different rest periods.

Design/methodology/approach
The blended geopolymer paste was composed of GGBS (15 per cent of the total weight) and the base material, Fly Ash (FA). The blended mix was activated by activator solution (Sodium hydroxide and Sodium silicate) containing 6 per cent Na2O of total base material. The effect of delayed water curing has been studied by gradually increasing the aging period (Rest Period) from 2 hours to 24 hours in the formation of activated outcome along with Calcium Silicate Hydrate (CSH). To analyze the mechanical and microstructural properties of the resultant blended geopolymer paste, compressive strength test, FESEM and XRD have been carried out. Moreover, a long-term durability test subjected to sulphate exposure has been performed to evaluate the durability of the designed sustainable geopolymer paste.

Findings
The present paper shows that the delayed water curing incorporates secondary heat input enhancing the partial polymer formation along with CSH. Slag-blended AAFA-based geopolymer paste is seen to exhibit quick setting property. Also, AAFA-based geopolymer paste samples subjected to longer rest period show early strength gain at a high rate under water curing as compared to those subjected to the shorter rest period.

Originality/value
To the best of authors’ knowledge, the effect of delayed water curing on the mechanical and microstructural properties of slag-blended AAFA-based geopolymer paste has not been studied before.
The potential for mass ratio and trait divergence effects to explain idiosyncratic impacts of non‐native invasive plants on carbon mineralization of decomposing leaf litter
Authors: Kuebbing Sara E. , Bradford Mark A. 
Published: February 2019

Abstract

Invasive plant effects on litter decomposition tend to be idiosyncratic among species and ecosystems, which may arise from variation in the invader’s relative abundance (mass ratio effect), from its relative functional difference to other species (trait divergence effect) and/or from species’ litter mixing that causes non‐additive decomposition rates relative to single‐species decomposition.

We use experimental microcosms to quantify the potential for mass ratio and trait divergence to explain effects of invasive litters on carbon mineralization rates of decomposing litter mixtures and to generate non‐additive dynamics in two distinct forest litter types.

The relative strength and direction of the mass ratio and trait divergence effects on carbon mineralization values were moderated by interactions between each effect and the canopy litter mixture. In both maple–poplar and oak–hickory litter mixtures, we found that the strength of the trait divergence effect increased with increasing proportions (mass ratio) of understorey litter in the litter mixtures, suggesting that interactions between these two mechanisms are important for moderating the influence of understorey invasions. Similarly, the addition of understorey litter always caused synergistic, non‐additive impacts on carbon mineralization, increasing carbon mineralization on average by 34%. For both litter mixtures, non‐additivity increased with increasing trait divergence between understorey and canopy litter.

Our findings show the potential for pronounced context‐dependency in the impact of non‐native invasive species that arise via multiple mechanism and their interactions. As such, they suggest the necessity of accounting for frequently theorized but infrequently tested mechanisms relating to mass ratio and trait divergence. Accounting should improve understanding of when mass ratio and trait divergence affect ecosystem process rates, and hence build confidence in mechanistic projections of invader impacts.

A new parameterization for generalized moveout approximation, based on three rays
Authors: Abedi Mohammad Mahdi , Stovas Alexey 
Published: February 2019

ABSTRACTA simple and accurate traveltime approximation is important in many applications in seismic data processing, inversion and modelling stages. Generalized moveout approximation is an explicit equation that approximates reflection traveltimes in general two‐dimensional models. Definition of its five parameters can be done from properties of finite offset rays, for general models, or by explicit calculation from model properties, for specific models. Two versions of classical finite‐offset parameterization for this approximation use traveltime and traveltime derivatives of two rays to define five parameters, which makes them asymmetrical. Using a third ray, we propose a balance between the number of rays and the order of traveltime derivatives. Our tests using different models also show the higher accuracy of the proposed method. For acoustic transversely isotropic media with a vertical symmetry axis, we calculate a new moveout approximation in the generalized moveout approximation functional form, which is explicitly defined by three independent parameters of zero‐offset two‐way time, normal moveout velocity and anellipticity parameter. Our test shows that the maximum error of the proposed transversely isotropic moveout approximation is about 1/6 to 1/8 of that of the moveout approximation that had been reported as the most accurate approximation in these media. The higher accuracy is the result of a novel parameterization that do not add any computational complexity. We show a simple example of its application on synthetic seismic data.

Published: February 2019

ObjectiveTo evaluate whether vaginoscopy or standard hysteroscopy was more successful in the outpatient setting.DesignRandomised controlled multicentre trial.SettingOutpatient hysteroscopy clinics at two UK hospitals.Population1597 women aged 16 or older undergoing an outpatient hysteroscopy.MethodsWomen were allocated to vaginoscopy or standard hysteroscopy using third party randomisation stratified by menopausal status with no blinding of participants or clinicians.Main outcome measuresThe primary outcome was ‘success’, a composite endpoint defined as: a complete procedure, no complications, a level of pain acceptable to the patient, and no sign of genitourinary tract infection 2 weeks after the procedure.ResultsVaginoscopy was significantly more successful than standard hysteroscopy [647/726 (89%) versus 621/734 (85%), respectively; relative risk (RR) 1.05, 95% CI 1.01–1.10; P = 0.01]. The median time taken to complete vaginoscopy was 2 minutes compared with 3 minutes for standard hysteroscopy (P < 0.001). The mean pain score was 42.7 for vaginoscopy, which was significantly less than standard hysteroscopy 46.4 (P = 0.02). Operative complications occurred in five women receiving vaginoscopy and 19 women receiving standard hysteroscopy (RR 0.26, 95% CI 0.10–0.69).ConclusionsVaginoscopy is quicker to perform, less painful, and more successful than standard hysteroscopy and therefore should be considered the technique of choice for outpatient hysteroscopy.Tweetable abstractVaginoscopy is quicker to perform, less painful, and more successful than standard hysteroscopy.

ObjectiveTo investigate the association between in vitro fertilisation IVF and severe maternal morbidity (SMM) and to explore the role of multiple pregnancy as an intermediate factor.DesignPopulation‐based cohort‐nested case–control study.SettingSix French regions in 2012/13.PopulationCases were 2540 women with SMM according to the EPIMOMS definition; controls were 3651 randomly selected women who gave birth without SMM.MethodsAnalysis of the associations between IVF and SMM with multivariable logistic regression models, differentiating IVF with autologous oocytes (IVF‐AO) from IVF with oocyte donation (IVF‐OD). The contribution of multiple pregnancy as an intermediate factor was assessed by path analysis.Main outcome measuresSevere maternal morbidity overall and SMM according to its main underlying causal condition and by severity (near misses).ResultsThe risk of SMM was significantly higher in women with IVF (adjusted OR = 2.5, 95% CI 1.8–3.3). The risk of SMM was significantly higher with IVF‐AO, for all‐cause SMM (aOR = 2.0, 95% CI 1.5–2.7), for near misses (aOR = 1.9, 95% CI 1.3–2.8), and for intra/postpartum haemorrhages (aOR = 2.3, 95% CI 1.6–3.2). The risk of SMM was significantly higher with IVF‐OD, for all‐cause SMM (aOR = 18.6, 95% CI 4.4–78.5), for near misses (aOR = 18.1, 95% CI 4.0–82.3), for SMM due to hypertensive disorders (aOR = 16.7, 95% CI 3.3–85.4) and due to intra/postpartum haemorrhages (aOR = 18.0, 95% CI 4.2–77.8). Path‐analysis estimated that 21.6% (95% CI 10.1–33.0) of the risk associated with IVF‐OD was mediated by multiple pregnancy, and 49.6% (95% CI 24.0–75.1) of the SMM risk associated with IVF‐AO.ConclusionThe risk of SMM is higher in IVF pregnancies after adjustment for confounders. Exploratory results suggest higher risks among women with IVF‐OD; however, confidence intervals were wide, so this finding needs to be confirmed. A large part of the association between IVF‐AO and SMM appears to be mediated by multiple pregnancy.Tweetable abstractThe risk of severe maternal morbidity is higher in IVF‐conceived pregnancies than in pregnancies conceived by other means.

AbstractObjectiveAsthma exacerbations are common presentations to ED. Key guideline recommendations for management include administration of inhaled bronchodilators, systemic corticosteroids and titrated oxygen therapy. Our aim was to compare management and outcomes between patients treated for asthma in Europe (EUR) and South East Asia/Australasia (SEA) and compliance with international guidelines.MethodsIn each region, prospective, interrupted time series studies were performed including adult (age >18 years) patients presenting to ED with the main complaint of dyspnoea during three 72 h periods. This was a planned sub‐study that included those with an ED primary diagnosis of asthma. Data was collected on demographics, clinical features, treatment in ED, diagnosis, disposition and in‐hospital outcome. The results of interest were differences in treatment and outcome between EUR and SEA cohorts.ResultsFive hundred and eighty‐four patients were identified from 112 EDs (66 EUR and 46 SEA). The cohorts had similar demographics and co‐morbidity patterns, with 89% of the cohort having a previous diagnosis of asthma. There were no significant differences in treatment between EUR and SEA patients – inhaled beta‐agonists were administered in 86% of cases, systemic corticosteroids in 66%, oxygen therapy in 44% and antibiotics in 20%. Two thirds of patients were discharged home from the ED.ConclusionThe data suggests that compliance with guideline‐recommended therapy in both regions, particularly corticosteroid administration, is sub‐optimal. It also suggests over‐use of antibiotics.
Omnipresent Maxwell's demons orchestrate information management in living cells

Published: February 2019

SummaryThe development of synthetic biology calls for accurate understanding of the critical functions that allow construction and operation of a living cell. Besides coding for ubiquitous structures, minimal genomes encode a wealth of functions that dissipate energy in an unanticipated way. Analysis of these functions shows that they are meant to manage information under conditions when discrimination of substrates in a noisy background is preferred over a simple recognition process. We show here that many of these functions, including transporters and the ribosome construction machinery, behave as would behave a material implementation of the information‐managing agent theorized by Maxwell almost 150 years ago and commonly known as Maxwell's demon (MxD). A core gene set encoding these functions belongs to the minimal genome required to allow the construction of an autonomous cell. These MxDs allow the cell to perform computations in an energy‐efficient way that is vastly better than our contemporary computers.
Dynamic assessment of sternoclavicular joint instability using four‐dimensional computed tomography

Published: February 2019

SummaryChronic post‐traumatic sternoclavicular joint (SCJ) instability can be debilitating and result in restriction of normal daily activities. The diagnosis can be difficult to make clinically or with the use of static imaging modalities. Wide‐volume dynamic four‐dimensional computed tomography (4D CT) can confidently diagnose chronic post‐traumatic SCJ instability. This can aid surgeons in pre‐operative planning and help to triage patients into surgical or non‐surgical candidates. We propose that 4D CT to be a routine pre‐operative imaging in patients with chronic post‐traumatic SCJ instability.
