A typology of the perceived risks in the context of consumer brand resistance
Authors: Cambefort Marine , Roux Elyette 
Published: March 2019

Purpose
This paper aims to provide a typology of perceived risk in the context of consumer brand resistance and thus answers the following question: how do consumers perceive the risk they take when resisting brands?

Design/methodology/approach
Two qualitative methods were used. In-depth interviews were carried out with 15 consumers who resist brands. An ethnography was carried out for ten months in an international pro-environmental NGO.

Findings
This multiple qualitative method design led to the identification of four types of risks taken by consumers. The four categories of perceived risks identified are performance (lack of suitable alternatives for the brand), social issues (stigma and exclusion), legal reasons (legal proceedings) or physical considerations (violation of physical integrity). These risks are located along a continuum of resistance intensity. Resistance intensity levels are avoidance, offline word-of-mouth, online word-of-mouth, boycott, activism and finally extreme acts.

Originality/value
This study provides a framework that integrates perceived risks within the context of brand resistance. The paper highlights extreme acts of resistance and questions the limits of such behaviors.
Wellness branding: insights into how American and Finnish consumers use wellness as a means of self-branding
Authors: Grénman Miia , Hakala Ulla , Mueller Barbara 
Published: March 2019

Purpose
The purpose of this paper is to examine wellness as a means of self-branding. The phenomenon is addressed through the introduction of a new concept – wellness branding – and by identifying those wellness practices that are currently most valued.

Design/methodology/approach
A series of focus group interviews were conducted in the USA and Finland. Altogether, 12 discussion sessions (N = 57) were carried out, 6 in each country.

Findings
Both wellness and self-branding represent current forms of identity and lifestyle construction and self-promotion. Moreover, they represent an entrepreneurial view of the self, which emphasizes self-governance. The findings indicate that wellness has moved beyond the merely physical dimension, to significantly involve emotional/mental, spiritual, social and intellectual aspects. This further strengthens the transformational nature of wellness and the increasing need for balancing one’s life in order to reach one’s optimal self. The logic of wellness branding involves the creation of one’s optimal, balanced self while communicating it to others.

Research limitations/implications
This paper makes insightful contributions to the branding literature by broadening the scope of self-branding to a new and timely context. The paper further adds to the consumer research literature by addressing wellness as a form of transformative consumption and an essential part of the current self-care culture.

Originality/value
To the authors’ knowledge, this paper is the first to discuss self-branding in the context of wellness, introducing a new concept of wellness branding, thus offering a novel area for research.
A dual portfolio approach to a student managed fund
Authors: Huerta Daniel , Pyles Mark 
Published: March 2019

Purpose
The purpose of this paper is to describe an investment program that offers students with the opportunity to simultaneously manage a private asset fund and a public asset fund. The program has been in operation since 2013 and has made significant progress in student placement and connectivity with local, regional and national financial firms.

Design/methodology/approach
The authors describe the structure, methods used and challenges encountered in this dual portfolio environment and add relevant thoughts for discussion. The authors discuss potential conflicts of interests that may arise in managing a private equity portfolio, the concern of proper deal flow, the issue of the investment timeline when investing in private equity and the problems encountered when measuring private equity performance.

Findings
While public asset funds have been around for decades and are relatively well accepted throughout all levels and types of higher education institutions. The uses of private equity funds, though not unheard of, are much less prevalent. Allowing the same group of students to manage both type of portfolios is relatively unique and provides with a more comprehensive learning experience.

Originality/value
A primary distinguishing attribute of this program is that accepted students are given the opportunity to simultaneously manage both public and private equity assets throughout an academic year. The goal is to create a comprehensive portfolio management program that replicates a changing investment management environment where private equity is an increasingly significant asset class.
Exploring changes of governance discourse of the National People’s Congress of the People’s Republic of China
Authors: Deng Hui-Wen , Cheung Kwok Wah 
Published: March 2019

Purpose
The National People’s Congress (NPC) of People’s Republic of China, the highest organ of state power, is popularly seen as a rubber-stamp entity. However, it has been substantially evolving its roles to accommodate the governance discourses within China’s political system over the decades. This study aims to explore the changes of governance discourse of the NPC within China’s political system through which to offer a thorough understanding of the NPC’s evolving substantial role in current China.

Design/methodology/approach
This study deploys a historical approach to explore the changes of governance discourse of the NPC that has seen a growing importance in China’s political agenda, as argued by this study.

Findings
The authors find that the NPC has been substantially evolving its role within China’s political system in which the Chinese Communist Party has created different governance discourses. Besides, the NPC and its Standing Committee have asserted its authority as a substantial actor within China’s political system. The NPC is no longer functioned as a rubber-stamp institution, though it is still popularized as a rubber stamp by many scholars.

Research limitations/implications
This study is a historical elaboration on the development of NPC under three governance discourses. It might be, to some extent, relatively descriptive in nature.

Originality/value
This study, therefore, sheds some light on a revisit on the governance discourses in current China.
Microbial responses to anthropogenic dissolved organic carbon in the Arctic and Antarctic coastal seawaters
Authors: Cerro‐Gálvez Elena , Casal Paulo , Lundin Daniel , Piña Benjamin , Pinhassi Jarone , Dachs Jordi , Vila‐Costa Maria 
Published: March 2019

SummaryThousands of semi‐volatile hydrophobic organic pollutants (OPs) reach open oceans through atmospheric deposition, causing a chronic and ubiquitous pollution by anthropogenic dissolved organic carbon (ADOC). Hydrophobic ADOC accumulates in cellular lipids, inducing harmful effects on marine biota, and can be partially prone to microbial degradation. Unfortunately, their possible effects on microorganisms, key drivers of global biogeochemical cycles, remain unknown. We challenged coastal microbial communities from Ny‐Ålesund (Arctic) and Livingston Island (Antarctica) with ADOC concentrations within the range of oceanic concentrations in 24 h. ADOC addition elicited clear transcriptional responses in multiple microbial heterotrophic metabolisms in ubiquitous groups such as Flavobacteriia, Gammaproteobacteria and SAR11. Importantly, a suite of cellular adaptations and detoxifying mechanisms, including remodelling of membrane lipids and transporters, was detected. ADOC exposure also changed the composition of microbial communities, through stimulation of rare biosphere taxa. Many of these taxa belong to recognized OPs degraders. This work shows that ADOC at environmentally relevant concentrations substantially influences marine microbial communities. Given that emissions of organic pollutants are growing during the Anthropocene, the results shown here suggest an increasing influence of ADOC on the structure of microbial communities and the biogeochemical cycles regulated by marine microbes.

Published: March 2019

Summary
Sinorhizobium fredii HH103 RifR, a broad‐host‐range rhizobial strain, forms ineffective nodules with Lotus japonicus but induces nitrogen‐fixing nodules in Lotus burttii roots that are infected by intercellular entry. Here we show that HH103 RifR nolR or nodD2 mutants gain the ability to induce infection thread formation and to form nitrogen‐fixing nodules in L. japonicus Gifu. Microscopy studies showed that the mode of infection of L. burttii roots by the nodD2 and nolR mutants switched from intercellular entry to infection threads (ITs). In the presence of the isoflavone genistein, both mutants overproduced Nod‐factors. Transcriptomic analyses showed that, in the presence of Lotus japonicus Gifu root exudates, genes related to Nod factors production were overexpressed in both mutants in comparison to HH103 RifR. Complementation of the nodD2 and nolR mutants provoked a decrease in Nod‐factor production, the incapacity to form nitrogen‐fixing nodules with L. japonicus Gifu and restored the intercellular way of infection in L. burttii. Thus, the capacity of S. fredii HH103 RifR nodD2 and nolR mutants to infect L. burttii and L. japonicus Gifu by ITs and fix nitrogen L. japonicus Gifu might be correlated with Nod‐factor overproduction, although other bacterial symbiotic signals could also be involved.
Do We Want a Referendum on the Common Market?
Authors: Duff Andrew 
Published: March 2019

AbstractIn March 1975 Britain quarrelled about whether to hold a referendum on membership of the European Community. The Hansard Society organised an important debate about it between Enoch Powell, Geoffrey Howe, John Mackintosh and Keith Kyle. This is a report on that event drawn from a recently discovered recording. Many of the arguments deployed then are being repeated in today's debate about a ‘people's vote'—including the long‐term effects on the UK's constitution of having recourse to the referendum device.
Oviposition preference and development of Maruca vitrata (Fabricius) (Lepidoptera: Crambidae) on different radiofrequency fields

Published: March 2019

AbstractMaruca vitrata is considered as one of the major impediments in boosting up the production of tropical legumes. Since chemical pesticides have an adverse effect on human health and environment, there is an urgent need for developing a non‐chemical based method to replace chemical insecticides for controlling of pests. We investigated the oviposition, development and adult performances of M. vitrata at five radiofrequency levels of 0 (control without frequency), 5, 10, 20, and 30 kHz on artificial diet. In addition, the effects were also studied in three successive generations (Parent, F1‐ and F2‐ generations) of M. vitrata. The results showed that radiofrequency application had significant effects on the life‐variables of M. vitrata. Radiofrequency exposures on M. vitrata not only impacted on oviposition, developmental time, adult longevity, and adult weight but negative effects were also transmitted to the successive generations. Oviposition was found to reduce as generation passed after exposed to radiofrequencies. Total developmental times from egg to adult emergence were longer with shorter longevity in case of radiofrequency treatment than untreated. Decreasing the radiofrequency level further increased time for development of adults as generation passed. The shortest adult longevity occurred at 5 kHz treatment. The outcomes of this study are discussed in terms of targeting susceptibilities to radiofrequency as an alternative to chemical treatments.
Visualization and characterization of Pseudomonas syringae pv. tomato DC3000 pellicles
Authors: Farias Gabriela A. , Olmedilla Adela , Gallegos María‐Trinidad 
Published: March 2019

SummaryCellulose, whose production is controlled by c‐di‐GMP, is a commonly found exopolysaccharide in bacterial biofilms. Pseudomonas syringae pv. tomato (Pto) DC3000, a model organism for molecular studies of plant–pathogen interactions, carries the wssABCDEFGHI operon for the synthesis of acetylated cellulose. The high intracellular levels of the second messenger c‐di‐GMP induced by the overexpression of the heterologous diguanylate cyclase PleD stimulate cellulose production and enhance air–liquid biofilm (pellicle) formation. To characterize the mechanisms involved in Pto DC3000 pellicle formation, we studied this process using mutants lacking flagella, biosurfactant or different extracellular matrix components, and compared the pellicles produced in the absence and in the presence of PleD. We have discovered that neither alginate nor the biosurfactant syringafactin are needed for their formation, whereas cellulose and flagella are important but not essential. We have also observed that the high c‐di‐GMP levels conferred more cohesion to Pto cells within the pellicle and induced the formation of intracellular inclusion bodies and extracellular fibres and vesicles. Since the pellicles were very labile and this greatly hindered their handling and processing for microscopy, we have also developed new methods to collect and process them for scanning and transmission electron microscopy. These techniques open up new perspectives for the analysis of fragile biofilms in other bacterial strains.
Yeast two‐ and three‐species hybrids and high‐sugar fermentation
Authors: Sipiczki Matthias 
Published: March 2019

SummaryThe dominating strains of most sugar‐based natural and industrial fermentations either belong to Saccharomyces cerevisiae and Saccharomyces uvarum or are their chimeric derivatives. Osmotolerance is an essential trait of these strains for industrial applications in which typically high concentrations of sugars are used. As the ability of the cells to cope with the hyperosmotic stress is under polygenic control, significant improvement can be expected from concerted modification of the activity of multiple genes or from creating new genomes harbouring positive alleles of strains of two or more species. In this review, the application of the methods of intergeneric and interspecies hybridization to fitness improvement of strains used under high‐sugar fermentation conditions is discussed. By protoplast fusion and heterospecific mating, hybrids can be obtained that outperform the parental strains in certain technological parameters including osmotolerance. Spontaneous postzygotic genome evolution during mitotic propagation (GARMi) and meiosis after the breakdown of the sterility barrier by loss of MAT heterozygosity (GARMe) can be exploited for further improvement. Both processes result in derivatives of chimeric genomes, some of which can be superior both to the parental strains and to the hybrid. Three‐species hybridization represents further perspectives.

AbstractWhile pest management tends to focus on pests that are already present in crops, non‐crop hosts may play a crucial role in supporting pest populations outside the crop growing season. Non‐crop hosts may allow pest populations to persist throughout the year, build‐up and colonise crops after emergence. Here, we assess the hosts of the Rutherglen bug, Nysius vinitor Bergroth, which is a polyphagous native insect pest of growing economic importance in Australia. We conducted a literature review on the occurrence of N. vinitor on crop and non‐crop hosts and analysed field survey data on N. vinitor abundance from two independent field studies in three agricultural regions of Australia. We differentiated between juvenile (nymph) and adult stages to consider the function of plants as reproduction sites. The literature review resulted in reports of N. vinitor on 44 crop species from 18 plant families. Pigweed Portulaca oleracea and capeweed Arctotheca calendula were the most cited weed hosts. In the field study, N. vinitor was primarily found on exotic weeds and grasses within pastures, Lucerne and degraded native vegetation remnants. While N. vinitor was found on a total of 16 weed plant families, juvenile stages of N. vinitor were most often observed on fleabane (Conyza spp.), goosefoot Chenopodium pumilio (Amaranthaceae) and plants of the Asteraceae family, indicating that these are important host plants for N. vinitor reproduction. Grasses appear to be an important but understudied host plant group; citations in the literature do not reflect the extent to which N. vinitor was found on grasses in the field. In contrast, the field survey indicated that very few native plant species supported N. vinitor, which was consistent across regions and confirms findings from the literature review. Our findings suggest that exotic weeds and grasses (but not native plants) play a key role in supporting N. vinitor populations in Australian agricultural landscapes. Reducing exotic weeds in pastures and non‐crop habitats may limit breeding opportunities of N. vinitor and may be an important component in the area‐wide management of this polyphagous pest.

Published: March 2019

BackgroundIntramedullary nailing (IMN) is generally accepted as the standard treatment for femoral shaft fractures. However, segmental femoral fractures are considered to be a special injury type associated with high complication rates. Combined IMN and plate is proved to be a reliable method for treating complex tibia fractures with less operation time and high union rates. Therefore, the purpose of our study is to evaluate the outcome of following combined IMN and plate fixation for segmental femoral fractures.MethodsBetween February 2013 and January 2016, 18 consecutive patients with femoral shaft fracture with AO/OTA type 32‐C2 were treated via combined IMN and plate. Surgical details, operative and postoperative complications, the rate of union and time to union were evaluated.ResultsThere were 14 men and four women with a mean age of 37.8 years (range 27–52 years). All patients were followed up for a minimum of 12 months. Of the patients, 13 were closed fractures, three were Gustilo type I open fractures and two were Gustilo type II open fractures. All patients achieved union within 18.9 weeks (range 12–28 weeks) and none of them had malunion. There were no deep infections, and two patients with superficial wound infections were successfully treated with antibiotics.ConclusionCombining IMN and plate fixation appears to be a reliable method for the treatment of segmental femoral shaft fractures with less operation time, high union rates and ability to maintain alignment, therefore it provides another choice for treating segmental femoral fractures.

AbstractPurposeA retrospective pilot study is conducted to demonstrate the utility of a novel support vector machine learning (SVML) algorithm in a small three‐dimensional (3D) sample yielding sparse optical coherence tomography (spOCT) data for the automatic monitoring of neovascular (wet) age‐related macular degeneration (wAMD).MethodsFrom the anti‐vascular endothelial growth factor injection database, 588 consecutive pairs of OCT volumes (57.624 B‐scans) were selected in 70 randomly chosen wAMD patients treated with ranibizumab. The SVML algorithm was applied to 183 OCT volume pairs (17.934 B‐scans) in 30 patients. Four independent, diagnosis‐blinded retina specialists indicated whether wAMD activity was present between 100 pairs of consecutive OCT volumes (9800 B‐scans) in the remaining 40 patients for comparison with the SVML algorithm and a non‐complex baseline algorithm using only retinal thickness. The SVML algorithm was assessed using inter‐observer variability and receiver operating characteristic (ROC) analyses.ResultsThe retina specialists showed an average Cohen's κ of 0.57 ± 0.13 (minimum: 0.41, maximum: 0.83). The average κ between the proposed algorithm and the retina specialists was 0.62 ± 0.05 and 0.43 ± 0.14 between the baseline algorithm and the retina specialists. Using each of the four retina specialists as the reference, the proposed method showed a superior area under the ROC curve of 0.91 ± 0.03 compared to the ROC 0.81 ± 0.05 shown by the baseline algorithm.ConclusionThe SVML algorithm was as effective as the retina specialists were in detecting activity in wAMD. Support vector machine learning (SVML) may be a useful monitoring tool in wAMD suited for small samples that yield sparse OCT data possibly derived from self‐measuring OCT‐robots.
