AbstractRhythmic patterning is central to the development of eukaryotes, particularly in plant shoot post-embryonic development. The plant hormone auxin drives rhythmic patterning at the shoot apical meristem, but the spatio-temporal dynamics of the auxin gradients is unknown. We used quantitative imaging to demonstrate that auxin provides high-definition graded information not only in space but also in time. We provide evidence that developing organs are auxin-emitting centers that could self-organize spatio-temporal auxin gradients through a transport network converging on the meristem center. We further show that a memory of the exposition of cells to auxin allows to differentiate temporally sites of organ initiation, providing a remarkable example of how the dynamic redistribution of a morphogenetic regulator can be used to create rhythmicity.

AbstractBackgroundA functional interplay between BAs and microbial composition in gut is a well-documented phenomenon. In bile this phenomenon is far less studied and with this report we describe the interactions between the BAs and microbiota in this complex biological matrix.MethodologyThirty-seven gallstone disease patients of which twenty-one withOpisthorchis felineusinfection were enrolled in the study. The bile samples were obtained during laparoscopic cholecystectomy for gallstone disease operative treatment. Common bile acids composition were measured by LC-MS/MS using a column in reverse phase. For all patients gallbladder microbiota was previously analyzed with 16S rRNA gene sequencing on Illumina MiSeq platform. The associations between bile acids composition and microbiota were analysed.Principal findingsBile acids signature andO. felineusinfection status exerts influence on beta-diversity of bile microbial community. Direct correlations were found between taurocholic acid, taurochenodeoxycholic acid concentrations and alpha-diversity of bile microbiota. Taurocholic acid and taurochenodeoxycholic acid both shows positive associations with the presence of Chitinophagaceae family,MicrobacteriumandLutibacteriumgenera andPrevotella intermedia. Also direct associations were identified for taurocholic acid concentration and the presence of Actinomycetales and Bacteroidales orders,Lautropiagenus,Jeotgalicoccus psychrophilusandHaemophilus parainfluenzaeas well as for taurochenodeoxycholic acid and Acetobacteraceae family and Sphingomonas genus. There were no differences in bile acids concentrations between O.felineusinfected and non-infected patients.Conclusions/SignificanceAssociations between diversity, taxonomic profile of bile microbiota and bile acids levels were evidenced in patients with cholelithiasis. Increase of taurochenodeoxycholic acid and taurocholic acid concentration correlates with bile microbiota alpha-diversity and appearance of opportunistic pathogens. Alteration of bile acids signature could cause shifts in bile microbial community structure.
MNC involvement in social innovations: the issue of knowledge, networks and power
Authors: Holmström Lind Christine , Kang Olivia , Ljung Anna , Forsgren Mats 
Published: November 2018

PurposeThis paper aims to develop a conceptual framework and presents a number of propositions relating to why and how multinational companies (MNCs) engage in social innovations. The central focus is on the role of MNC knowledge, networks and power for their involvement in social innovations.Design/methodology/approachThe authors combine literature on social innovations, business innovations and MNC literature, and present a number of propositions dealing with the link between MNC knowledge, networks and power-relations and their potential involvement in social innovations.FindingsThe authors emphasize that when social innovations are embraced by MNCs, the way that these corporations use their knowledge, networks and existing power-relations needs to be adapted to the new conditions present in the social innovation arena.Research limitations/implicationsThe main limitation of this work is that the propositions are based on anecdotal evidence and that they are restricted to literature revolving around a few theoretical concepts (knowledge, networks, power). Against this, the authors suggest that to address the call for more empirical work on MNCs engagement in social innovation, these concepts could be used as a starting point in future empirical investigations.Originality/valueThe paper brings together and outlines a theoretical framework based on three theoretical approaches to the MNC as suggested by the literature: the knowledge-based MNC, differentiated MNC and political MNC. Based on these three perspectives, the key contribution of this paper is to develop a broader understanding of why and how MNCs engage in social innovation and the potential underlying liabilities for this involvement.

Published: November 2018

PurposeFounded on the concept of organizational ambidexterity and the competing value model, the purpose of this paper is to develop an information technology (IT) ambidexterity framework to underscore the importance of a balanced and harmonious IT environment in enterprise cloud adoption.Design/methodology/approachWith survey responses from 165 IT executives in a managerial position who are in charge of cloud computing implementation, partial least square method is used to test the research model.FindingsCloud absorptive capacity plays an important role for firms to secure a competitive advantage. The synergy of the two capabilities (flexibility and control), which have conflicting characteristics, contributes to the enhancement of cloud absorptive capacity and leads to a firm’s knowledge accumulation and performance.Research limitations/implicationsThis study is the very first attempt that empirically establishes the relationship between a firm’s competitiveness and cloud computing absorptive capacity. This study provides a comprehensive framework that integrates ambidexterity theory with the competing value framework (CVF) with extending the concept of absorptive capacity that is bounded within an organizational perspective into a cloud computing context.Practical implicationsFirms should treat cloud computing as a strategic consideration to secure a competitive advantage in the contemporary business environment. For a firm’s performance, a dual governance structure, that encompasses flexibility and control, is required to achieve competitive advantage from cloud computing adoption.Originality/valueTo facilitate organizational effort in achieving a harmonious cloud environment, the authors propose a comprehensive ambidexterity framework integrating the CVF approach. This framework maps IT ambidexterity onto the CVF. As CVF considers internal and external factors that ambidexterity theory does not cover, integrating two theories can provide more comprehensive implications and discussions regarding cloud computing adoption.

PurposeThis article examines how responsibility and strategy can and should be connected in a business organization.Design/methodology/approachThe article offers a review of the field by mapping previous studies according to their strategy and responsibility orientations and, consequently, identifies the classic perspective, as well as the major deficiencies and prevailing research gaps in the literature.FindingsThe article contributes to the field of strategic corporate responsibility by reframing the field with a contender perspective that challenges the classic view of strategy and responsibility amalgamation. Together, the classic and the contender perspectives are synthesized to form an integrative perspective that is more holistic than those currently available.Originality/valueThe article ends by calling for a reimagining of the relationship between corporate responsibility and strategy to find promising future research avenues and effective business practices suitable to meet the challenges of the twenty-first century.
Cue-less consumers in factory outlet stores: reference price effects on consumer evaluations when semantic phrases are missing
Authors: Carlson Jay P. , Compeau Larry D. 
Published: November 2018

Purpose
Prior research has demonstrated that reference prices can affect consumer responses, but the reference prices examined have been presented along with semantic cues [e.g. manufacturer’s suggested retail price (MSRP) and Compare At]. This study is unique in investigating the effects of reference prices that do not include a semantic cue (i.e. “cue-less”) on consumers’ responses. It also studies consumers’ beliefs about factory outlet stores, a seldom-studied store type in which cue-less reference prices are used.

Design/methodology/approach
One qualitative study and one experiment were carried out in this research.

Findings
The qualitative study revealed that a price tag including cue-less reference prices was unlikely to be viewed as a seller mistake or with suspicion, but nonetheless did confuse some respondents. The experiment demonstrated that while consumers find cue-less reference prices to be somewhat less believable that high MSRPs, these beliefs do not appear to come into play when consumers judge attractiveness (e.g. perceived value). Additionally, the results suggest that consumers believe that a product available for sale in a factory outlet store is likely to have been previously available at a different type of store.

Originality/value
This research advances the theory of the effects of reference prices on consumers’ responses by examining the common practice of not labeling reference prices with semantic cues. It also extends the literature regarding consumer beliefs about factory outlet stores.
Digital banking, customer experience and financial performance
Authors: Mbama Cajetan Ikechukwu , Ezepue Patrick , Alboul Lyuba , Beer Martin 
Published: November 2018

Purpose
This study aims to examine managers’ perceptions of digital banking’s (DB) effect on customer experience and banks’ financial performance.

Design/methodology/approach
The research uses interviews from the senior UK bank managers to gather their views on DB’s impact on customer experience and financial performance. The interviews were thematically analysed to produce results and a model.

Findings
The attributes affecting DB experience are as follows: service quality, functional quality, perceived value, service customisation, service speed, employee–customer engagement, brand trust, DB innovation, perceived usability and perceived risk. They affect customer experience, satisfaction and loyalty and financial performance. The research revealed relationships amongst these attributes (e.g. brand trust and loyalty).

Research limitations/implications
The study is a UK bank specific and can be replicated in other developed countries’ banks, helping in further comparison. However, DB is conducted globally, which implies that the findings are robust enough to be potentially applied in other countries. The proposed model shows customer experience drivers and outcomes through managers’ views, which can be theoretically tested.

Practical implications
The findings suggest important attributes (as above) for consideration to improve DB customer experience and financial performance. They show the relevance of employee–customer interaction, service personalisation, value proposition, quality service offering and DB experience, which have useful implications for improving DB design and interactive marketing.

Originality/value
Gauging DB customer experience as perceived by bank managers has not been studied in this way, highlighting DB effectiveness, which is important for multi-channel marketing and banks’ financial performance, and advances theory.

Abstract

Apple is considered the most important fruit crop in temperate areas and profitable production depends on multiple ecosystem services, including the reduction of pest damage and the provision of sufficient pollination levels. Management approaches present an inherent trade‐off as each affects species differently.

We quantified the direct and indirect effects of management (organic vs. integrated pest management, IPM) on species richness, ecosystem services, and fruit production in 85 apple orchards in three European countries. We also quantified how habit composition influenced these effects at three spatial scales: within orchards, adjacent to orchards, and in the surrounding landscape.

Organic management resulted in 48% lower yield than IPM, and also that the variation between orchards was large with some organic orchards having a higher yield than the average yield of IPM orchards. The lower yield in organic orchards resulted directly from management practices, and from higher pest damage in organic orchards. These negative yield effects were partly offset by indirect positive effects from more natural enemies and higher flower visitation rates in organic orchards.

Two factors other than management affected species richness and ecosystem services. Higher cover of flowering plants within and adjacent to the apple trees increased flower visitation rates by pollinating insects and a higher cover of apple orchards in the landscape decreased species richness of beneficial arthropods.

The species richness of beneficial arthropods in orchards was uncorrelated with fruit production, suggesting that diversity can be increased without large yield loss. At the same time, organic orchards had 38% higher species richness than IPM orchards, an effect that is likely due to differences in pest management.

Synthesis and applications. Our results indicate that organic management is more efficient than integrated pest management in developing environmentally friendly apple orchards with higher species richness. We also demonstrate that there is no inherent trade‐off between species richness and yield. Development of more environmentally friendly means for pest control, which do not negatively affect pollination services, needs to be a priority for sustainable apple production.
Melatonin in the seasonal response of the aphid Acyrthosiphon pisum
Authors: Barberà Miquel , Escrivá Laura , Collantes‐Alegre Jorge Mariano , Meca Giuseppe , Rosato Ezio , Martínez‐Torres David 
Published: November 2018

AbstractAphids display life cycles largely determined by the photoperiod. During the warm long‐day seasons, most aphid species reproduce by viviparous parthenogenesis. The shortening of the photoperiod in autumn induces a switch to sexual reproduction. Males and sexual females mate to produce overwintering resistant eggs. In addition to this full life cycle (holocycle), there are anholocyclic lineages that do not respond to changes in photoperiod and reproduce continuously by parthenogenesis. The molecular or hormonal events that trigger the seasonal response (i.e., induction of the sexual phenotypes) are still unknown. Although circadian synthesis of melatonin is known to play a key role in vertebrate photoperiodism, the involvement of the circadian clock and/or of the hormone melatonin in insect seasonal responses is not so well established. Here we show that melatonin levels in the aphid Acyrthosiphon pisum are significantly higher in holocyclic aphids reared under short days than under long days, while no differences were found between anholocyclic aphids under the same conditions. We also found that melatonin is localized in the aphid suboesophageal ganglion (SOG) and in the thoracic ganglionic mass (TGM). In analogy to vertebrates, insect‐type arylalkylamine N‐acetyltransferases (i‐AANATs) are thought to play a key role in melatonin synthesis. We measured the expression of four i‐AANAT genes identified in A. pisum and localized two of them in situ in the insect central nervous systems (CNS). Levels of expression of these genes were compatible with the quantities of melatonin observed. Moreover, like melatonin, expression of these genes was found in the SOG and the TGM.
Comparative analyses of susceptibility to chemicals associated with fermentation between Drosophila melanogaster and Drosophila suzukii

Published: November 2018

AbstractDrosophila melanogaster Meigen and Drosophila suzukii Matsumura are taxonomically close Drosophila species belonging to the family Drosophilidae and melanogaster group. D. melanogaster is thought to be evolutionarily adapted to overripe, decaying, and fermented fruits, in which large amounts of chemicals such as ethanol, acetic acid, and 2‐phenylethanol are produced, whereas, D. suzukii is attracted to fresh ripening fruit. Considering the distinct habitats of the two flies, D. suzukii is hypothesized to exhibit higher susceptibility to these chemicals than D. melanogaster. Therefore, in this study, we investigated the survival rate of the flies at various concentrations of three chemicals (2‐phenlyethanol, acetic acid, and ethanol) and calculated the lethal concentration (LC) values to compare the tolerance and susceptibility of D. melanogaster and D. suzukii to the chemicals. Our results revealed that D. melanogaster exhibited higher tolerance than D. suzukii to all chemicals, supporting the hypothesis of different evolutionary adaptations to distinct habitats of the two flies.

Published: November 2018

AbstractAs the vector‐borne diseases rapidly increased due to climate change, we investigated the incidence of flavivirus occurrence among female mosquito species in urban and rural study sites in Daegu and Gunwi, South Korea using Realtime PCR. We collected more individuals and more species of mosquito in 2016 than in 2015. In 2015, we recorded a total of 22,033 mosquitoes (Trap Index, 224.8) representing 10 species from 5 genera, whereas in 2016, a total of 27,137 mosquitoes (Trap Index, 278.7) representing 13 species from 6 genera were collected. The number of mosquitoes in 2016 was higher in all study sites, except in the migratory bird habitats where the number decreased. Of the 14 species collected over the two years,Aedes vexans nipponii and Anophelesspp. were dominant in the cowsheds in rural farmland;Culex pipienscomplex, in urban residential areas; and,Anophelesspp. andCu. pipienscomplex in migratory bird habitats caught in a black light trap.Cu. pipienscomplex andAe. albopictusin urban parks andAe. albopictusandArmigeres subalbatusin migratory bird habitats were the dominant species caught in BG‐sentinel traps. We found that the number of mosquitoes was highest during July–September. We analyzed 1,725 pools to detect flavivirus, where Chaoyang virus was detected amongAe. vexans niponiicollected from cowsheds in rural farmland in 2016. The increased number of mosquitoes recorded in 2016 was mainly due to increased temperatures in the study areas, and reflected the change in study sites.
Breast cancer diagnosis in a specialised breast clinic: Are cancers detected by ultrasound alone less aggressive?

Published: November 2018

AbstractIntroductionThe aim of this study was to determine the relationship between the way breast cancer is diagnosed and its prognostic features.MethodsWe studied new primary invasive and non‐invasive breast cancers (670) diagnosed between 2013 and 2015 where detection included at least clinical examination, mammography and breast ultrasound (BUS). The cancers were classified into six Diagnostic Groups according to the results of each modality.ResultsOverall, 79% of cancers were positive on mammography, but another 20% were diagnosed on BUS after a negative mammogram. The largest group (37.6% of cases), had all three modalities positive (Group 1). BUS was the only modality positive in 14.6% (Group 4). Mammography alone was positive in 21.2%, of which 73.9% were ductal carcinoma in situ (DCIS). Invasive lobular carcinoma comprised 9.6% of the groups where mammography was positive, but 16.5% of the groups where mammography was negative and BUS positive. Dense breast tissue was more common in the groups where mammography was negative and BUS positive. Invasive cancers comprised 82.7% of Group 4 and 95.2% of Group 1. For those in Group 4, the average size (10.2 mm) and the percentages with lymphovascular invasion (11.1%), lymph node involvement (17.3%) and poor differentiation (12.3%) were less than half the corresponding figures for Group 1 (27.3 mm, 35%, 44%, 44%).ConclusionThis study illustrates the complementary benefits of mammography and BUS, especially where breast density is high. Tumours diagnosed by BUS alone had better prognostic features in terms of size, lymphovascular invasion, lymph node status, differentiation and hormone receptors, compared with cancers where all three modalities were positive.
