Comparing benefit- and attribute-based menu assortments: an exploratory study
Authors: Kwon Eunjin , Mattila Anna 
Published: January 2017

PurposeThe purpose of this paper is to examine the joint effects of menu pages (single page vs multiple pages) and assortment organization (benefit- vs attribute-based) on consumers’ perceptions of variety with large assortments.Design/methodology/approachA 2 (assortment structure: single page vs multiple pages)×2 (assortment organization: benefit- vs attribute-based) experimental between-subjects design was used to test the hypotheses.FindingsThe results suggest that with a one-page tea menu, participants perceived greater variety with the attribute-based (e.g. black teas, herbal teas, green teas, and oolong teas) menu than with the (e.g. energy-boosting, stress-relief, weight loss, and immune system-improvement) benefit-based menu. Conversely, when the menu was displayed on four pages, participants showed similar perceptions of variety across the two menu types.Research limitations/implicationsIn some contexts, 20 menu items may not be considered a large assortment. Also, the authors did not test consumers’ preexisting preferences.Practical implicationsWhen food service operators offer an extensive benefit-based menu, it is advisable to place the options over multiple pages. If the menu needs to be displayed on a single spatial unit (e.g. a black board, or applications on a tablet or smartphone), practitioners should organize the menu based on attributes rather than benefits.Originality/valueAlthough the demand for healthy dining options has led many foodservice operators to apply benefit-based organization to items on their menus, for example, by using terms such as “energy-boosting,” “stress-relief,” “weight-loss,” and “immune system-improvement,” little is known about the effectiveness of such a strategy.
Value drivers and adventure tourism
Authors: Williams Paul , Soutar Geoff , Ashill Nicholas Jeremy , Naumann Earl 
Published: January 2017

Purpose
The purpose of this paper is to investigate the drivers of customer value, and their respective relationships with customer satisfaction and behavioral intentions, between two culturally distinct groups of adventure tourists.

Design/methodology/approach
The study adopted a descriptive design and compared data from 301 Japanese and Western adventure tourists who experienced the same adventure tour. The respondents were split into two groups, and a path modeling approach was used to examine similarities and differences.

Findings
The results indicated that Japanese tourists attached more importance to emotional value and novelty value. Western tourists, however, attached relatively more importance to the utilitarian dimension of price value for money.

Practical implications
The main implication of this study is that tourism operators should account for differences in value perceptions between Japanese and Western tourists when planning tour operations, training tour guides, and managing tour itineraries. Operators should also consider customizing their tour products to fit the specific needs of these different cultural groups. This reinforces the adaptation argument when marketing tourism to international consumers.

Originality/value
This study highlights that different value drivers affect the satisfaction and behavioral intentions of Japanese tourists, relative to Western tourists. The need for adaptation of tourism products toward certain international tourists is thus necessary. The research also reinforces the importance of conceptualizing and measuring customer value as a multidimensional construct in an international adventure tourism context.
The moderating effect of supervisor and coworker support for error management on service recovery performance and helping behaviors
Authors: Pasamehmetoglu Aysin , Guchait Priyanko , Tracey J.B. , Cunningham Christopher J.L. , Lei Puiwa 
Published: January 2017

Purpose
The purpose of this paper is to amend and extend the emerging research that has utilized an employee-focused approach to examining the service recovery process. In doing so, the authors examine the influences of supervisor and coworker support for error management on two measures of employee service performance: service recovery performance and helping behaviors during service failure and recoveries. Specifically, this study examines the linear and non-linear interaction effects of supervisor and coworker support for error management on the outcome variables.

Design/methodology/approach
To examine the proposed relationships, the authors conducted a field study that utilized survey data from a sample of 243 restaurant employees and their immediate supervisors. Employee ratings of supervisor and coworker support for error management were matched with the data gathered for the two dependent variables (i.e. supervisory ratings of service recovery performance and helping behaviors). Structural equation modeling was used to examine the linear interaction effects on the outcome variables. To examine the non-linear interaction effects on the outcome variables the authors utilized polynomial regression and response surface modeling.

Findings
The results showed that the interaction effects of supervisor and coworker support for error management was significantly positively related to both service recovery performance and helping behaviors. In addition, an alternative analysis of the shape of the interaction effects using polynomial regression and response surface modeling showed that the moderating effects may be better conceptualized as non-linear.

Originality/value
These findings offer new insights about the roles and impact of various forms of support in the service recovery process. First, the current study focuses specifically on supervisor and coworker support for error management and the impact on employees’ service recovery performance and helping behaviors. Second, this research investigates the interaction effects of these two forms of support on service recovery performance and helping behaviors. Third, along with linear interaction effects, the current work examines non-linear interaction effects. These relationships examined in this study have not been tested before. Thus, the findings of this research make a unique contribution to research in service management. The findings of this study provide more prescriptive insights about the means to prevent and respond effectively to service errors.
Response surface methodology (RSM) mediated interaction of media concentration and process parameters for the pigment production by Monascus purpureus MTCC 369 under solid state fermentation
Authors: Sehrawat Rachna , Panesar Paramjit S. , Swer Tanya L. , Kumar Anit 
Published: January 2017

Purpose
This paper aims to extract colour from micro-organisms (as a source of natural pigments) using agro-industrial substrates to replace synthetic media by solid state fermentation. Nature is filled with colours. Due to health and environmental consciousness among people, use of synthetic colour has declined, and so the need to develop colour from cheap and easily available natural sources (plants, animals, micro-organisms and algae) using a cost-effective technique with higher yield and rapid growth. Monascus purpureus colour is a potent source of compounds (Dimerumic acid, Monacolin-k and -aminobutyric acid) having antimutagenic, antimicrobial and antiobesity, which helps in combating diseases.

Design/methodology/approach
Response surface methodology was used to optimise the biopigments extraction from Monascus purpureus using solid state fermentation.

Findings
The best optimised conditions for biopigments production using Monascus purpureus MTCC 369 were pH 5.4 at 32°C for 8 days 9 hours (8.9 days) from sweet potato peel and pea pod powder, 7.8 (w/w) and 3.9 per cent (w/w), respectively, which gave a final yield of 21 CVU/g. The model F-value of 69.18 and high value of adjusted determination coefficient 96.00 per cent implies high level of significance of the fitted model.

Practical implications
Extracted colour can be used in beverages, confectionery and pharmaceutical industries.

Social implications
Colour produced using Monascus purpureus MTCC 369 is a natural source. As consumers are reluctant to use synthetic colour because of the undesirable allergic reactions caused by them, so a biopigment produced is natural colouring compound with wide application in food sector.

Originality/value
Selected sources of carbon and nitrogen were not used earlier by any researcher to extract biopigment from Monascus purpureus MTCC 369.

Authors: Çanak Tuba Çakır , Vurur Ömer Faruk , Serhatlı İ. Ersin 
Published: January 2017

Purpose
This paper aims to investigate effects of acrylic functionalisation of multiwalled carbon nanotubes (MWCNTs) on properties of carbon nanotubes/epoxy nanocomposites.

Design/methodology/approach
A number of analytical techniques, including Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy and transmission electron microscopy, were used to assess the effects of acid treatment on MWCNTs. Ultraviolet-curable coatings were fabricated by sonication and cast moulding process. The mechanical properties of MWCNTs/epoxy composites at different weight fractions were evaluated by performing tensile tests and dynamic mechanical analysis tests. Also, gel contents were examined.

Findings
It was found that addition of nanotubes monomer to epoxy formulations had significant effect on the viscoelastic and mechanical properties.

Practical implications
Improving dispersion and alignment of MWCNTs in the composite matrix will contribute to the development of resin/MWCNTs nanocomposites and promote the applications.

Originality/value
The paper establishes a method to introduce MWCNTs into epoxy matrix as a monomer to enhance the photo curable and dispersion properties of the MWCNT/epoxy films.

Published: January 2017

SummaryThe study of complex microbial communities poses unique conceptual and analytical challenges, with microbial species potentially numbering in the thousands. With transient or allochthonous microorganisms often adding to this complexity, a ‘core’ microbiota approach, focusing only on the stable and permanent members of the community, is becoming increasingly popular. Given the various ways of defining a core microbiota, it is prudent to examine whether the definition of the core impacts upon the results obtained. Here we used complex marine sponge microbiotas and undertook a systematic evaluation of the degree to which different factors used to define the core influenced the conclusions. Significant differences in alpha‐ and beta‐diversity were detected using some but not all core definitions. However, findings related to host specificity and environmental quality were largely insensitive to major changes in the core microbiota definition. Furthermore, none of the applied definitions altered our perception of the ecological networks summarising interactions among bacteria within the sponges. These results suggest that, while care should still be taken in interpretation, the core microbiota approach is surprisingly robust, at least for comparing microbiotas of closely related samples.
The PacC transcription factor regulates secondary metabolite production and stress response, but has only minor effects on virulence in the insect pathogenic fungus Beauveria bassiana

Published: January 2017

SummaryThe PacC transcription factor is an important component of the fungal ambient pH‐responsive regulatory system. Loss of pacC in the insect pathogenic fungus Beauveria bassiana resulted in an alkaline pH‐dependent decrease in growth and pH‐dependent increased susceptibility to osmotic (salt, sorbitol) stress and SDS. Extreme susceptibility to Congo Red was noted irrespective of pH, and ΔBbpacC conidia showed subtle increases in UV susceptibility. The ΔBbPacC mutant showed a reduced ability to acidify media during growth due to failure to produce oxalic acid. The ΔBbPacC mutant also did not produce the insecticidal compound dipicolinic acid, however, production of a yellow‐colored compound was noted. The compound, named bassianolone B, was purified and its structure determined. Despite defects in growth, stress resistance, and oxalate/insecticidal compound production, only a small decrease in virulence was seen for the ΔBbpacC strain in topical insect bioassays using larvae from the greater waxmoth, Galleria mellonella or adults of the beetle, Tenebrio molitor. However, slightly more pronounced decreases were seen in virulence via intrahemcoel injection assays (G. mellonella) and in assays using T. molitor larvae. These data suggest important roles for BbpacC in mediating growth at alkaline pH, regulating secondary metabolite production, and in targeting specific insect stages.
Have Free Trade Agreements Created Trade? Evidence from CEPA
Authors: Zhou Yonghong 
Published: January 2017

AbstractThis paper revisits the issue of trade creation effects in multi‐stage free trade agreements (FTA). In contrast to the empirical studies that use the gravity equation to study trade creation effects, we apply a triple difference in differences approach to resolve their shortcomings, including factors being omitted and endogeneity. After the identification of treatment and control groups at the eight‐digit Harmonized System (HS) code product level, the regression analysis results show that there are no significant trade creation effects with the FTA, suggesting that the role of FTA may be a signalling beyond trade.

Published: January 2017

AbstractBiologic anti‐tumor necrosis factor (TNF) drugs have demonstrated their efficacy for the treatment of ulcerative colitis. Nevertheless, some patients will not respond to this therapy or will develop loss of response. Leukapheresis is the main non‐pharmacological therapy for some immune‐mediated diseases. The aim of our study was to describe our experience with this therapy in ulcerative colitis patients after loss of response to anti‐TNF treatment. Leukapheresis was indicated in four patients with left‐sided or extensive colitis because of partial response to biological therapy or secondary loss of response to it. All patients received 8 to 10 sessions in an intensive regimen. Globally, a decrease in the Mayo score was observed. The overall response rate was 50% with one patient who displayed sustained response. No patients have required colectomy during follow‐up. Adjuvant treatment with leukapheresis in patients with inadequate response to anti‐TNF treatment showed some beneficial effect, although of limited duration, in patients with ulcerative colitis.
Women on boards and greenhouse gas emission disclosures
Authors: Hollindale Janice , Kent Pamela , Routledge James , Chapple Larelle 
Published: January 2017

AbstractWe apply institutional and board capital theory to examine whether women on boards are associated with disclosure and quality of corporate greenhouse gas (GHG) emissions related reporting. We examine the research problem in Australia in a period when no requirements existed for listed companies to appoint female directors or to report GHG emissions. This environment allows us to examine the association between women on boards and GHG emissions related disclosure in annual and sustainability reports in a voluntary setting. We find that companies with multiple female directors make GHG emissions related disclosures that are of higher quality.
Further evidence of the relationship between accruals and future cash flows
Authors: Farshadfar Shadi , Monem Reza M. 
Published: January 2017

AbstractFocusing only on operating accruals in accrual‐based studies results in a loss of information and noisy measures of both accrual and cash flow components of earnings. Thus, we examine the relative importance of working capital accruals, non‐current operating accruals, and financing accruals with regard to future cash flows from operations (CFO). Using Australian data, we provide evidence that both working capital and non‐current operating accruals are important for explaining future CFO but that the contribution of financing accruals is not significant. Moreover, the asset component of accruals plays a more important role in explaining future CFO than the liability component.

SummaryBackgroundTreatment of chronic hepatitis C genotype 3 (GT3) is more challenging compared with other genotypes. Since 2014, several new treatment regimens have been approved but sometimes based on limited data.AimTo validate the use, effectiveness and safety of anti‐viral treatment in chronic hepatitis C genotype 3 infection under real‐word conditions.MethodsThe German Hepatitis C‐Registry is a large national non‐interventional real‐world study for patients with chronic hepatitis C. A total of 1322 GT3 patients were enrolled (211 untreated and 1111 treated patients).ResultsBetween February 2014 and September 2015, five different treatment strategies have been used (PegIFN+RBV, PegIFN+RBV+SOF, SOF+RBV, DCV+SOF±RBV, LDV/SOF±RBV). Treatment uptake and use of treatment concepts changed markedly and rapidly during the study influenced by new approvals, guideline recommendations, and label updates. PegIFN‐based therapies constantly declined while DCV‐based therapies increased with one interruption after the approval of LDV/SOF, which was frequently used until new guidelines recommended not using this combination for GT3. Per‐protocol SVR ranged from 80.9% in the PegIFN+RBV group to 96.1% in PegIFN+RBV+SOF treated patients. Treatment‐experienced patients with cirrhosis showed a suboptimal SVR of 68% for SOF+RBV but a high SVR of 90–95% for DCV+SOF±RBV. The safety analysis showed more adverse events and a stronger decline of haemoglobin for RBV containing regimens.ConclusionsReal‐world data can validate the effectiveness and safety for treatment regimens that had previously been approved with limited data, in particular for specific subgroups of patients. The present study demonstrates how rapid new scientific data, new treatment guidelines, new drug approvals and label changes are implemented into routine clinical practice today.
Systematic review with meta‐analysis: rifaximin is effective and safe for the treatment of small intestine bacterial overgrowth
Authors: Gatta L. , Scarpignato C. 
Published: January 2017

SummaryBackgroundSmall intestinal bacterial overgrowth (SIBO) is a heterogeneous syndrome, characterised by an increased number and/or abnormal type of bacteria in the small bowel. Over the past decades, rifaximin has gained popularity for this indication despite its use is not evidence based.AimTo perform a systematic review and meta‐analysis to summarise evidence about the efficacy and safety of rifaximin to eradicate SIBO in adult patients.MethodsMEDLINE, EMBASE, CCRCT, Scopus and Web of Science were searched from inception to March 16, 2015 for RCTs and observational studies. Furthermore, abstract books of major European, American and Asian gastroenterological meetings were also examined.ResultsThirty‐two studies involving 1331 patients were included. The overall eradication rate according to intention‐to‐treat analysis was 70.8% (95% CI: 61.4–78.2; I2 = 89.4%) and to per protocol analysis 72.9% (95% CI: 65.5–79.8; I2 = 87.5%). Meta‐regression identified three covariates (drug dose, study design and co‐therapy) independently associated with an increased eradication rate. The overall rate of adverse events was 4.6% (95% CI: 2.3–7.5; I2 = 63.6%). In the subset of studies (n= 10) allowing the analysis, improvement or resolution of symptoms in patients with eradicated SIBO was found to be 67.7% (95% CI: 44.7–86.9; I2 = 91.3%).ConclusionsRifaximin treatment seems to be effective and safe for the treatment of SIBO. However, the quality of the available studies is generally poor. Well‐designed RCTs are needed to substantiate these findings and to establish the optimal regimen.

SummaryBackgroundPrebiotics have been shown to reduce abdominal symptoms in patients with functional gut disorders, despite that they are fermented by colonic bacteria and may induce gas‐related symptoms.AimTo investigate changes in the metabolic activity of gut microbiota induced by a recognised prebiotic.MethodsHealthy subjects (n = 20) were given a prebiotic (2.8 g/day HOST‐G904, HOST Therabiomics, Jersey, Channel Islands) for 3 weeks. During 3‐day periods immediately before, at the beginning and at the end of the administration subjects were put on a standard diet (low fibre diet supplemented with one portion of high fibre foods) and the following outcomes were measured: (i) number of daytime gas evacuations for 2 days by means of an event marker; (ii) volume of gas evacuated via a rectal tube during 4 h after a test meal; and (iii) microbiota composition by faecal Illumina MiSeq sequencing.ResultsAt the beginning of administration, HOST‐G904 significantly increased the number of daily anal gas evacuations (18 ± 2 vs. 12 ± 1 pre‐administration; P < 0.001) and the volume of gas evacuated after the test meal (236 ± 23 mL vs. 160 ± 17 mL pre‐administration; P = 0.006). However, after 3 weeks of administration, these effects diminished (11 ± 2 daily evacuations, 169 ± 23 mL gas evacuation). At day 21, relative abundance of butyrate producers (Lachnospiraceae) correlated inversely with the volume of gas evacuated (r = −0.52; P = 0.02).ConclusionThe availability of substrates induces an adaptation of the colonic microbiota activity in bacterial metabolism, which produces less gas and associated issues.
