The effect of service employees’ accent on customer reactions
Authors: Tombs Alastair , Rao Hill Sally 
Published: November 2014

Purpose
– The primary objective of this article is to investigate customer reactions to service employees with accents that differ from a non-native accent taking into account customer emotions.

Design/methodology/approach
– This article reports on a study with a 2 (accent of service employee: Australian or Indian) × 2 (service employee’s competency: competent or incompetent) × 2 (customer’s affective state: positive or negative) between-subject experimental design to uncover the effects of service employees’ accent on customers’ reactions.

Findings
– The findings revealed that hearing a service employee with a foreign accent was not enough on its own to influence customer responses. However, when the service employee is incompetent or the customer was in a negative affective state, a foreign accent appeared to exacerbate the situation.

Research limitations/implications
– While the findings indicate that accents are used a cue for customers to evaluate service employees, further research should also take service types, service outcomes, customer-service employee relationships, customers’ ethnic affiliation and ethnocentrism into consideration when examining the effect of accents.

Practical implications
– Service managers need to be aware that accents will exacerbate perceptions of already difficult service situations. Providing competent service will help breakdown stereotypes and improve the acceptance of diversity at the customer–employee interface.

Originality/value
– This article contributes to the service literature about service attributes and is particularly relevant to economies such as the USA, Canada, the UK, New Zealand and Australia where immigrants are a large part of the service work force.
The impact of text product reviews on sales
Authors: Moon Sangkil , Park Yoonseo , Seog Kim Yong 
Published: November 2014

Purpose– The aim of this research is to theorize and demonstrate that analyzing consumers’ text product reviews using text mining can enhance the explanatory power of a product sales model, particularly for hedonic products, which tend to generate emotional and subjective product evaluations. Previous research in this area has been more focused on utilitarian products.Design/methodology/approach– Our text clustering-based procedure segments text reviews into multiple clusters in association with consumers’ numeric ratings to address consumer heterogeneity in taste preferences and quality valuations and the J-distribution of numeric product ratings. This approach is novel in terms of combining text clustering with numeric product ratings to address consumers’ subjective product evaluations.Findings– Using the movie industry as our empirical application, we find that our approach of making use of product text reviews can improve the explanatory power and predictive validity of the box-office sales model.Research limitations/implications– Marketing scholars have actively investigated the impact of consumers’ online product reviews on product sales, primarily focusing on consumers’ numeric product ratings. Recently, studies have also examined user-generated content. Similarly, this study looks into users’ textual product reviews to explain product sales. It remains to be seen how generalizable our empirical results are beyond our movie application.Practical implications– Whereas numeric ratings can indicate how much viewers liked products, consumers’ reviews can convey why viewers liked or disliked them. Therefore, our review analysis can help marketers understand what factors make new products succeed or fail.Originality/value– Primarily our approach is suitable to products subjectively evaluated, mostly, hedonic products. In doing so, we consider consumer heterogeneity contained in reviews through our review clusters based on their divergent impacts on sales.
Developing a conceptual model for examining the supply chain relationships between behavioural antecedents of collaboration, integration and performance
Authors: S. Tsanos Christos , G. Zografos Konstantinos , Harrison Alan 
Published: November 2014

Purpose
– The purpose of this paper is threefold: first, review the literature on the topic of behavioural antecedents of collaboration and their impact on supply chain integration and performance; second, lay the theoretical foundations and develop a conceptual model linking behavioural antecedents of collaboration, information integration, coordination of operational decisions and supply chain performance; and third, set out operationalisation considerations.

Design/methodology/approach
– A conceptual model with theoretical basis on Relational Exchange Theory (RET) and extant supply chain theory is developed as a causal model that can be operationalised using structural equations modelling (partial least squares) and a “single key informant” approach.

Findings
– Positive relationships between behavioural antecedents of collaboration (trust, commitment, mutuality/reciprocity), information integration, coordination of operational decisions and supply chain performance (efficiency, effectiveness) are hypothesised. RET provides adequate theoretical background that leads to the theoretical establishment of hypotheses between behavioural antecedents, supply chain integration and performance, which are worth testing empirically.

Research limitations/implications
– The ideas presented in this paper enrich the study of behavioural factors in supply chain management and their impact on supply chain performance, and may benefit researchers in the field. The paper also sets the scene (experimental design, measurement items) for the upcoming field research. The empirical part of the work will provide the necessary evidence for the validation of the established hypotheses.

Practical implications
– The proposed linkages may stimulate the interest of supply chain strategists towards more collaborative relationship management and affect their decisions on the behavioural antecedents of relationship formation and management. Moreover, the proposed model may help clarify how the integration of critical operational contingencies – information, operational decisions – can help achieve superior supply chain performance.

Originality/value
– The paper establishes a causal relationship between constructs which have not been researched (mutuality/reciprocity, coordination of operational decisions) or have been researched individually or in combination (impact of integration on performance, impact of collaboration on performance) but not in the proposed integrated way. It also addresses the challenge of lack of theoretical justification on the development of knowledge that will assist decision making in SCM/logistics and its integration into models, processes and tasks. Finally, by using RET in selecting of behavioural factors and establishing hypotheses, it adds to the body of knowledge concerning the use of interorganisational theories in supply chain relationships.
Beyond the negative relation between return and conditional volatility in the wine market
Authors: I. Bouri Elie 
Published: November 2014

Purpose
– The purpose of this paper is to examine fine wine’s safe-haven status with respect to US equity movements.

Design/methodology/approach
– We use a generalized autoregressive conditional heteroscedasticity model and its variant to measure the asymmetric reaction to positive and negative shocks.

Findings
– Our empirical results show an inverted asymmetric volatility in the wine market; positive shocks increase the conditional volatility more than negative shocks. That is the opposite reaction in the volatility of equity returns occurs in the wine market. As leverage effect and volatility feedback effect do not adequately explain this reaction, we follow the work of Baur (2012) and propose the safe haven effect. Several robustness tests largely confirm the empirical findings, with major implications for wine investors. Finally, we provide further evidence on the benefits of adding wine investments to an equity portfolio through an increase in risk reduction effectiveness.

Research limitations/implications
– Based on the results of the robustness analysis, the recommendations in terms of including fine wines in portfolios must be issued with caution.

Practical implications
– Our findings are crucial to the needs of market participants who are interested in including wine assets in their equity portfolio.

Originality/value
– No previous study investigates the safe haven property of fine wine return, and accounts for risk reduction effectiveness when adding wine assets to a portfolio of US equities.
The plan behind the scan: using QR codes as a service and marketing tool
Authors: Berndt-Morris Elizabeth , Chrenka Kari 
Published: November 2014

Purpose
– This paper aims to describe the approach of using quick response (QR) codes in a large US research university library. It describes the reasoning behind the numerous decisions that were made throughout the process.

Design/methodology/approach
– This project was carefully planned to keep detailed organized statistics, effective and clear signage and low expenditures. After one year, the patrons were surveyed regarding library QR use and those results were compared with scan statistics.

Findings
– This preliminary research into the use of QR codes in a large research library validates that the codes effectively demonstrate the Library’s willingness to reach patrons in innovative ways. It also confirmed the need to promote the usefulness of scanning the codes.

Practical implications
– Some patrons stated they did not own a smartphone or have an application (app) on their phone that could scan QR codes; therefore, alternate methods of accessing the information should be provided.

Social implications
– The survey established that not all patrons recognize what QR codes are by name and/or by function, and libraries should recognize this need for education when imploring new technologies.

Originality/value
– This paper looks at the opportunities provided to libraries through the use of QR codes, including the benefits of using them as a point of need service tool and marketing device.
Suicide risk in the UK trans population and the role of gender transition in decreasing suicidal ideation and suicide attempt
Authors: Bailey Louis , J. Ellis Sonja , McNeil Jay 
Published: November 2014

Purpose
– The purpose of this paper is to present findings from the Trans Mental Health Study (McNeil et al., 2012) – the largest survey of the UK trans population to date and the first to explore trans mental health and well-being within a UK context. Findings around suicidal ideation and suicide attempt are presented and the impact of gender dysphoria, minority stress and medical delay, in particular, are highlighted.

Design/methodology/approach
– This represents a narrative analysis of qualitative sections of a survey that utilised both open and closed questions. The study drew on a non-random sample (n=889), obtained via a range of UK-based support organisations and services.

Findings
– The study revealed high rates of suicidal ideation (84 per cent lifetime prevalence) and attempted suicide (48 per cent lifetime prevalence) within this sample. A supportive environment for social transition and timely access to gender reassignment, for those who required it, emerged as key protective factors. Subsequently, gender dysphoria, confusion/denial about gender, fears around transitioning, gender reassignment treatment delays and refusals, and social stigma increased suicide risk within this sample.

Research limitations/implications
– Due to the limitations of undertaking research with this population, the research is not demographically representative.

Practical implications
– The study found that trans people are most at risk prior to social and/or medical transition and that, in many cases, trans people who require access to hormones and surgery can be left unsupported for dangerously long periods of time. The paper highlights the devastating impact that delaying or denying gender reassignment treatment can have and urges commissioners and practitioners to prioritise timely intervention and support.

Originality/value
– The first exploration of suicidal ideation and suicide attempt within the UK trans population revealing key findings pertaining to social and medical transition, crucial for policy makers, commissioners and practitioners working across gender identity services, mental health services and suicide prevention.
Efficacy of processing treatments on cypermethrin residues in okra (Abelmoschus esculentus)
Authors: Tomer Vidisha , Sangha Jasvinder Kaur , Singh Balwinder , Takkar Reenu 
Published: November 2014

Purpose
– This paper aims to study the effect of different processing treatments to reduce cypermethrin residues in okra and judge the consumer preferences of the applied unit operations. Deliberate use of pesticides on vegetables has been frequently reported in recent past. Association of pesticides with multiple health odds in human beings necessitates its removal from diet.

Design/methodology/approach
– Cypermethrin residues were analysed using Quick Easy Cheap Effective Rugged Safe method and quantified using gas chromatography. Consumer acceptability was judged using a 9-point Hedonic scale.

Findings
– Significant reductions were observed in all treatments applied. Percentage reduction observed with different pre-treatments ranged from 36 per cent (tap water) to 89 per cent (acetic acid and potassium permanganate). All cooking methods, except microwave cooking, were found effective, as the per cent reduction varied from 91 to 98 per cent. Maximum reductions were observed with pressure cooking. However, on the basis of organoleptic scores, washing was the most preferred pre-treatment, followed by sodium bicarbonate. Least score was obtained by samples treated with potassium permanganate. Among the cooking methods, all samples were acceptable, except pressure cooking. Taking into consideration both factors, i.e. residue reduction and consumer acceptability, sodium bicarbonate, sodium chloride and frying were found to be the best household treatments.

Originality/value
– Present study pioneered and tried to establish links between the efficacies of laboratory to the consumer level, thereby judging its utility. Further research must focus on taking this parameter of food safety to real applied research at the consumer level.
The effect of anthropogenic arsenic contamination on the earthworm microbiome
Authors: Pass Daniel Antony , Morgan Andrew John , Read Daniel S. , Field Dawn , Weightman Andrew J. , Kille Peter 
Published: November 2014

SummaryEarthworms are globally distributed and perform essential roles for soil health and microbial structure. We have investigated the effect of an anthropogenic contamination gradient on the bacterial community of the keystone ecological species Lumbricus rubellus through utilizing 16S rRNA pyrosequencing for the first time to establish the microbiome of the host and surrounding soil.The earthworm‐associated microbiome differs from the surrounding environment which appears to be a result of both filtering and stimulation likely linked to the altered environment associated with the gut micro‐habitat (neutral pH, anoxia and increased carbon substrates). We identified a core earthworm community comprising Proteobacteria (∼50%) and Actinobacteria (∼30%), with lower abundances of Bacteroidetes (∼6%) and Acidobacteria (∼3%). In addition to the known earthworm symbiont (Verminephrobacter sp.), we identified a potential host‐associated Gammaproteobacteria species (Serratia sp.) that was absent from soil yet observed in most earthworms.Although a distinct bacterial community defines these earthworms, clear family‐ and species‐level modification were observed along an arsenic and iron contamination gradient. Several taxa observed in uncontaminated control microbiomes are suppressed by metal/metalloid field exposure, including eradication of the hereto ubiquitously associated Verminephrobacter symbiont, which raises implications to its functional role in the earthworm microbiome.

SummaryThe ubiquitous filamentous fungus Fusarium graminearum causes the important disease Fusarium head blight on various species of cereals, leading to contamination of grains with mycotoxins. In a survey of F. graminearum (sensu stricto) on wheat in North America several novel strains were isolated, which produced none of the known trichothecene mycotoxins despite causing normal disease symptoms. In rice cultures, a new trichothecene mycotoxin (named NX‐2) was characterized by liquid chromatography‐tandem mass spectrometry. Nuclear magnetic resonance measurements identified NX‐2 as 3α‐acetoxy‐7α,15‐dihydroxy‐12,13‐epoxytrichothec‐9‐ene. Compared with the well‐known 3‐acetyl‐deoxynivalenol (3‐ADON), it lacks the keto group at C‐8 and hence is a type A trichothecene. Wheat ears inoculated with the isolated strains revealed a 10‐fold higher contamination with its deacetylated form, named NX‐3, (up to 540 mg kg−1) compared with NX‐2. The toxicities of the novel mycotoxins were evaluated utilizing two in vitro translation assays and the alga Chlamydomonas reinhardtii. NX‐3 inhibits protein biosynthesis to almost the same extent as the prominent mycotoxin deoxynivalenol, while NX‐2 is far less toxic, similar to 3‐ADON. Genetic analysis revealed a different TRI1 allele in the N‐isolates, which was verified to be responsible for the difference in hydroxylation at C‐8.

Published: November 2014

SummaryMultiyear comparisons of bacterioplankton succession reveal that environmental conditions drive community shifts with repeatable patterns between years. However, corresponding insight into bacterioplankton dynamics at a temporal resolution relevant for detailed examination of variation and characteristics of specific populations within years is essentially lacking. During 1 year, we collected 46 samples in the Baltic Sea for assessing bacterial community composition by 16S rRNA gene pyrosequencing (nearly twice weekly during productive season). Beta‐diversity analysis showed distinct clustering of samples, attributable to seemingly synchronous temporal transitions among populations (populations defined by 97% 16S rRNA gene sequence identity). A wide spectrum of bacterioplankton dynamics was evident, where divergent temporal patterns resulted both from pronounced differences in relative abundance and presence/absence of populations. Rates of change in relative abundance calculated for individual populations ranged from 0.23 to 1.79 day−1. Populations that were persistently dominant, transiently abundant or generally rare were found in several major bacterial groups, implying evolution has favoured a similar variety of life strategies within these groups. These findings suggest that high temporal resolution sampling allows constraining the timescales and frequencies at which distinct populations transition between being abundant or rare, thus potentially providing clues about physical, chemical or biological forcing on bacterioplankton community structure.
The Use of Forensic Tests to Distinguish Blowfly Artifacts from Human Blood, Semen, and Saliva
Authors: Durdle Annalisa , Mitchell R. John , van Oorschot Roland A.H. 
Published: November 2014

AbstractThis study investigated whether routinely used forensic tests can distinguish 3‐day‐old or 2‐week‐old fly artifacts, produced after feeding on human blood, semen, or saliva, from the biological fluid. Hemastix®, Hemident™, and Hemascein™ were unable to distinguish blood from artifacts. Hemastix® returned false positives from negative controls. ABAcard® Hematrace® and Hexagon OBTI could distinguish blood from 3‐day‐old artifacts, but not 2‐week‐old artifacts. Phadebas® and SALIgAE® were unable to distinguish saliva from artifacts. RSID™‐Saliva was able to distinguish saliva from 3‐day‐old artifacts, but not 2‐week‐old artifacts. Semen tests Seminal Acid Phosphatase, RSID™‐Semen, and ABAcard® p30 were all able to distinguish semen from 3‐day‐old artifacts, but not 2‐week‐old artifacts. The tests investigated cannot be relied upon to distinguish artifacts from biological fluids. However, if an artifact is identified by its morphology, a positive result may indicate which biological fluid the fly consumed, and this knowledge may prove useful for investigators searching for DNA.

Published: November 2014

SummaryThe study of environmental samples requires a preservation system that stabilizes the sample structure, including cells and biomolecules. To address this fundamental issue, we tested the cell alive system (CAS)‐freezing technique for subseafloor sediment core samples. In the CAS‐freezing technique, an alternating magnetic field is applied during the freezing process to produce vibration of water molecules and achieve a stable, super‐cooled liquid phase. Upon further cooling, the temperature decreases further, achieving a uniform freezing of sample with minimal ice crystal formation. In this study, samples were preserved using the CAS and conventional freezing techniques at 4, −20, −80 and −196 (liquid nitrogen) °C. After 6 months of storage, microbial cell counts by conventional freezing significantly decreased (down to 10.7% of initial), whereas that by CAS‐freezing resulted in minimal. When Escherichia coli cells were tested under the same freezing conditions and storage for 2.5 months, CAS‐frozen E. coli cells showed higher viability than the other conditions. In addition, an alternating magnetic field does not impact on the direction of remanent magnetization in sediment core samples, although slight partial demagnetization in intensity due to freezing was observed. Consequently, our data indicate that the CAS technique is highly useful for the preservation of environmental samples.
