Antecedents and outcomes of online brand engagement
Authors: Loureiro Sandra Maria Correia , Gorgus Tatjana , Kaufmann Hans Ruediger 
Published: September 2017

Purpose
The purpose of this paper is to investigate the antecedents and outcomes of online consumer brand engagement (OCBE). In addition, a mediator effect of satisfaction and brand love in the relationship between OCBE and positive electronic word-of-mouth (e-WOM) is analyzed.

Design/methodology/approach
Data were collected using a panel sampling with 201 participants from the millennial generation provided by the software tool Qualtrics. The online questionnaire is composed of two screening questions, the items of the constructs and a section with the socio-demographic variables.

Findings
Involvement and online brand experience (OBE) are important drivers of online brand engagement. Brand love is a significant mediator between online brand engagement and e-WOM.

Originality/value
Studies about antecedents and outcomes of online consumer engagement are rare. This paper contributes to the fledgling online consumer engagement literature by analyzing three antecedents: involvement, OBE, and self-brand image congruency. For the first time, brand love and satisfaction were considered as direct outcomes of online brand engagement. New insights are provided into the mediating role of brand love between online brand engagement and e-WOM.
Sharing co-creation experiences contributes to consumer satisfaction
Authors: Alarcón López Rocío , Ruiz de Maya Salvador , López López Inés 
Published: September 2017

Purpose
The purpose of this paper is to analyze the effects of sharing co-creation experiences on consumers’ behavioral intentions. Increasingly often, companies interact with consumers and involve them in value co-creation, especially in the virtual environment, while more and more consumers tend to share their experiences and their related emotions socially. However, no research has addressed how the interplay of these two variables influences consumer behavior.

Design/methodology/approach
The authors conducted a preliminary study and a 2×2 between-subjects experiment where co-creation and sharing of emotions were orthogonally manipulated. A total of 120 participants were randomly assigned to one of the four scenarios.

Findings
The results show that not only do individuals participate in co-creation activities, but they also tend to share such experiences socially. But more important from a literature contribution perspective, the results confirm a joint effect of co-creation and sharing on satisfaction and repurchase intention. Thus, the effect of co-creation can be bolstered by encouraging participants to share the experience with other people.

Originality/value
While we can better understand the effects of co-creation in particular contexts effects such as that of sharing, the findings also contribute to the theoretical literature on social sharing of emotions as it has not been related to co-creation activities before. The results are of special relevance for those companies implementing co-creation activities, as they provide clues to increase the outcome of such initiatives in terms of consumers’ responses toward the firm.
Expectations and provocations
Authors: Kmita Maria 
Published: September 2017

Purpose
The purpose of this paper is to address participants’ humorous provocations as a part of informal interactions between participants and researcher that can be treated just like the research data. By means of autoethnographic analysis, the author explores the expectations of the researcher and participants that humour research entails and discusses how different expectations are revealed in participants’ provocations.

Design/methodology/approach
This paper uses an autoethnographic approach to discuss the informal interactions between participants and the researcher gathered during research into staffroom humour. The informal interactions in general and humour specifically were recorded, analysed, coded, interpreted and theorised just like the data on humour between participants. The theoretical framework used in the study combines Goffman’s (1959) version of symbolic interactionism and Solomon et al. (2006) idea of hybrid spaces.

Findings
The study shows the need for reconsideration of expectations entangled in humour research and proposes to be prepared for unexpected. Expecting unexpected can help stay open minded in the field and in interactions with participants and apply healthy distance towards own research and own expectations. The study shows that whenever certain behaviour was expected and different behaviour was delivered, there was a chance for certain behaviour being interpreted as provocations. Participants’ provocations can result from their own expectations about the research or what they think is expected from them by the researcher and thus they remain subject to different interpretations.

Research limitations/implications
Further research could investigate and discuss the role of humour in participant-researcher interactions in different research contexts and across different methodologies. Combining and analysing experiences of use of humour from both participants and researchers could allow for creating the guidelines in the use of humour in different research situations. Ethical challenges posed by informal interactions between researcher and participants could be explored further and suggestions as to how to protect the researcher, research and participants in such interactions could be developed.

Originality/value
This paper aims to be a starting point for a discussion about the understudied relationship between expectations humour research is entangled with and participants’ provocations. The study shows innovative approach to informal interactions between participants’ and researcher which are treated as research data and are theorised using original combination of symbolic interactionism and hybrid spaces. The study contributes to the qualitative research methodology by discussing the ethics of both using humour with participants and recording and analysing informal humorous interactions between participants and the researcher.
Herd behavior in the French stock market
Authors: Litimi Houda 
Published: September 2017

Purpose
This paper aims to investigate the herding behavior in the French stock market and its effect on the idiosyncratic conditional volatility at a sectoral level.

Design/methodology/approach
This sample covers all the listed companies in the French stock market, classified by sector, over four major crisis periods. The author modifies the cross-sectional absolute deviation (CSAD) model to include trading volume and investors sentiment as herding triggers. Furthermore, the author uses a modified GARCH model to investigate the effect of herding on conditional volatility.

Findings
Herding is present in the French market during crises, and it is present in only some sectors during the entire period. The main trigger for investors to embark into a collective herding movement differs from one sector to another. Furthermore, herding behavior has an inhibiting effect on market conditional volatility.

Originality/value
The author modifies the CSAD model to investigate the presence of herding in the French stock market at a sectoral level during turmoil periods. Furthermore, the particularly designed GARCH model provides new insights on the effect of herding and volume turnover on the conditional volatility.
The perception of risk by international travellers
Authors: Carballo Rita R. , León Carmelo J. , Carballo María M. 
Published: September 2017

PurposeThis paper aims to investigate the perception of risk by international travellers. There are multiple risks facing tourism that contribute to the formation of perception of risk. It is necessary to identify the different types of risks that are perceived in tourist destinations. This paper suggests policies and techniques to mitigate the risk perceptions in tourism.Design/methodology/approachA preliminary questionnaire survey was conducted to test the types of risks that are perceived in international destinations. The data were further analysed with factor analysis to measure the dimension of risk perceptions.FindingsThe main results point to the existence of five types of risk affecting tourists during international travel: health risk, risk of suffering from crime and delinquency, accident risk, environmental risk and risk from disasters. Result shows that uncontrollable risks are perceived as more important than those which are more controllable.Originality/valueAs the existing literature on perception of risk in tourism does not contain a substantially detailed discussion relating to types of risk in international destinations and its contribution to the formation of risk perceptions, this paper may contribute to a better understanding of risk perception. The results could assist in decision-making and have implications for the management of risks.
Molecular phylogeny and taxonomic implications of Asarum (Aristolochiaceae) based on ITS and matK sequences
Authors: Takahashi Daiki , Setoguchi Hiroaki 
Published: September 2017

AbstractThe genus Asarum (Aristolochiaceae) encompasses approximately 120 species from five sections. Taxonomic controversies concerning the genus Asarum and/or its intrageneric classification remain unresolved. In particular, sect. Heterotropa accounts for a large percentage of the genus (80 of 120 species) and is well diverged in the Sino–Japanese Forest subkingdom. Reconstruction of Heterotropa phylogeny and estimation of its divergence times would provide significant insight into the process of species diversity in the Sino–Japanese floristic region. This study encompassed 106 operational taxonomic units (OTUs), and phylogenetic analyses were conducted based on internal transcribed spacer (ITS) and matK sequences. Although the matK sequences provided informative results solely for section Geotaenium, phylogenetic trees based on ITS regions yielded a clear result for several sections. Three sections, Asarum, Geotaenium and Asiasarum, were supported as robust monophyletic groups, whereas Heterotropa had low support. Sect. Hexastylis was revealed to be polyphyletic, suggesting taxonomic reconstruction would be needed. Sect. Heterotropa comprises two clades, which correspond to species distribution ranges: mainland China and the island arc from Taiwan to mainland Japan via the Ryukyu Islands. It is notable that the common ancestry of the latter clade in the eastern Asian islands was highly supported, suggesting that the present species diversity of Heterotropa was initially caused by allopatric range fragmentation in East Asia.

AbstractAimDecisions regarding adjuvant chemotherapy for early breast cancer are complex. Ki67 is increasingly used, in conjunction with conventional prognostic markers, to help decide the use of adjuvant chemotherapy for early breast cancer. Ki67 has been proposed as an economical alternative to Oncotype DX recurrence score (RS), which is a validated prognostic marker for disease recurrence and predictive marker for benefit from chemotherapy. This study aimed to determine in patients where conventional prognostic markers did not provide a clear recommendation for adjuvant chemotherapy, whether Ki67 could be a substitute for RS.MethodsWe reviewed all cases of luminal‐type node‐negative early breast cancer (T1‐2, N0‐1mi, M0, estrogen receptor positive, HER2 negative) referred for Oncotype DX testing by the multidisciplinary team at an Australian tertiary private hospital from 14th December 2006 to 31st December 2013, when conventional prognostic markers did not provide a clear recommendation for adjuvant chemotherapy. RS was correlated with Ki67, along with other conventional prognostic markers including tumor size, grade, mitotic rate and lymphovascular invasion. Spearman's rank order correlation coefficient and Pearson product‐moment correlation coefficient (r) were used for ordinal and continuous variables, respectively.ResultsA total of 58 patients were analyzed, median Ki67 was 15% (range 2–50%) and the median RS was 16 (range 3–65). There was no positive correlation between Ki67 and RS (r = 0.01, P = 0.93). No single conventional prognostic marker was shown to significantly correlate with RS, including tumor size (r = −0.02, P = 0.88), grade (r = 0.10, P = 0.44), mitotic rate (r = −0.07, P = 0.69) and lymphovascular invasion (r = −0.12, P = 0.39).ConclusionKi67 and conventional prognostic markers do not correlate with Oncotype DX RS. In the setting where conventional prognostic markers do not show a clear indication for or against adjuvant chemotherapy as determined by consensus in a multidisciplinary team, Ki67 is not a substitute for Oncotype DX testing. RS may provide additional information to aid decision making for adjuvant chemotherapy.

Published: September 2017

ObjectiveTo measure the prevalence of internal tandem duplications (ITDs) in exon 11 of the proto‐oncogene C‐KIT in a sample of Australian cutaneous canine mast cell tumours (MCTs) drawn from general practice and to evaluate relationships between tumour mutation status and prognostic factors including signalment, tumour histological grade, tumour anatomical location and tumour size.Methods
C‐KIT exon 11 ITDs were detected by PCR in DNA extracted from formalin‐fixed, paraffin‐embedded canine MCTs sourced from three veterinary diagnostic laboratories in Adelaide and Melbourne. Tumours were graded according to two different systems (Patnaik and Kiupel systems) by board‐certified anatomical pathologists blinded to the PCR results. Relationships between tumour mutation status and prognostic factors were evaluated using a generalised binary logistic regression analysis.ResultsITDs were identified in 13 of 74 cutaneous canine MCT samples, giving an overall prevalence of 17.6% (95% confidence interval: 8.9–26.2%). ITDs were detected in 10 of 18 Patnaik grade III MCTs (55.6%) and 11 of 22 Kiupel high‐grade MCTs (50%). Wald chi‐square analysis revealed that detection of tumour ITDs was significantly associated with both Patnaik’s and Kiupel’s histologic grading systems (each: P < 0.001). The presence of the ITDs in MCTs was not associated with signalment, tumour anatomical location or tumour size.ConclusionThe prevalence of C‐KIT exon 11 ITDs in Australian canine MCTs is similar to the prevalence in overseas canine populations (overall prevalence in Australia approximately 18%). ITDs were more frequently identified in higher grade MCTs.

SummaryWe assessed the safety and efficacy of bortezomib, cyclophosphamide and dexamethasone (VCD) induction therapy in previously untreated multiple myeloma patients. A total of 414 patients received three 21‐day cycles of VCD prior to autologous stem‐cell transplantation (ASCT). Most common grade ≥3 adverse events were leucopenia (31·4%) and thrombocytopenia (6·8%). The overall response rate (ORR) by investigator‐based assessment was 85·4%. Most patients (74%) underwent successful central laboratory‐based molecular cytogenetic analysis. No clinically relevant differences in ORR post‐induction were seen between patients with or without high‐risk cytogenetic abnormalities (86·2% vs. 84·3%). Further follow‐up data are available for 113 patients receiving ASCT who were included in a prospective consolidation trial (median follow‐up, 55·5 months); median progression‐free survival (PFS) was 35·3 months and median overall survival (OS) was not reached. In patients with high‐risk versus standard‐risk cytogenetics, median PFS was 19·9 vs. 43·6 months (P < 0·0001), and median OS was 54·7 months versus not reached (P = 0·0022). VCD is an effective and tolerable induction regimen; results suggest that VCD induces high response rates independently of cytogenetic risk status, but after long‐term follow‐up, cytogenetic high risk is associated with markedly reduced PFS and OS post‐ASCT.

Published: September 2017

SummaryA 14‐year‐old boy with relapsed T cell acute lymphoblastic leukaemia received reinduction chemotherapy that included nelarabine, a purine nucleoside analogue known to cause dose‐dependent neurotoxicity. Although he achieved aminimal residual disease negative remission after two cycles of chemotherapy he also developed severe, progressive peripheral and central neurotoxicities. Loss of grey‐white differentiation was seen on a T2‐weighted magnetic resonance imaging brain scan. This unusual clinical picture and previously unreported radiological findings are thought to be due to nelarabine toxicity. He was bridged with 6‐mercaptopurine while transplant was deferred pending sustainable neurological improvement. This case posed clinical and ethical dilemmas while demonstrating previously unreported radiological features.
Negotiating deficiency: Exploring ethnic minority parents' narratives about encountering child welfare services in Norway
Authors: Fylkesnes Marte Knag , Iversen Anette Christine , Nygren Lennart 
Published: September 2017

AbstractEvaluating the participatory opportunities for service users within social welfare institutions is a pressing issue. In this article, we explore a group of ethnic minority parents' experiences with child welfare services (CWS) in Norway. A strong narrative theme was deficiency positioning—how lacking a Norwegian normative set of knowledge and skills challenged the parents' opportunities to participate. We analysed how deficiency positioning was perceived, negotiated, and contested in the parents' accounts, and 4 themes emerged: (a) learning to parent, (b) contesting expert knowledge, (c) learning to be a client, and (d) constructing CWS deficiency. Nancy Fraser's concept of “participatory parity” was applied to explore how current institutional structures may enable and limit parents' participation. The analysis provides insight into agencies and informants' sense‐making processes as well as the diverse resources and strategies that parents draw upon in the CWS encounter. Furthermore, we argue that an interplay between a strong focus on “parenting skills” and bureaucratic and economic structures positions ethnic minority parents as deficient, thus providing powerful mechanisms for marginalization. Implications for case work and institutional levels are discussed.

SummaryBackgroundIn 2011, a multicentre study was conducted in order to determine how hair dye manufacturers instructed consumers to perform a self‐test prior to dyeing their hair, in order to identify individuals who are likely to react upon subsequent hair dyeing. A number of concerns were raised concerning the variability in instructions between products and producers, and the safety and validity of this tool.ObjectivesTo perform a 5‐year follow‐up study in order to determine whether manufacturers still recommend a self‐test, and if so, whether the procedures have been changed.MethodsDuring March 2016, a total of 40 oxidative hair dye products from 21 different manufacturers were bought in retail stores in 8 European countries.ResultsThe consumers were instructed to perform a self‐test prior to hair dyeing for 39 of the products; however, the procedures varied greatly regarding the method of application, the amount of hair dye applied, the location and size of the application area, the number of applications, whether or not rinsing was performed after application, the reading times, and how a positive reaction was defined.ConclusionsSelf‐testing is still recommended by almost all manufacturers of permanent hair dyes. There are major variations in the instructions, even in products from the same manufacturer. The previously raised concerns regarding safety and validity still remain.

AbstractAimTo assess the outcomes of rectal suspension procedures (forms of rectopexy) in adults with chronic constipation.MethodStandardised methods and reporting of benefits and harms were used for all CapaCiTY reviews that closely adhered to PRISMA 2016 guidance. Main conclusions were presented as summary evidence statements with a summative Oxford Centre for Evidence‐Based Medicine (2009) level.ResultsEighteen articles were identified, providing data on outcomes in 1238 patients. All studies reported only on laparoscopic approaches. Length of procedures ranged between 1.5 to 3.5 h, and length of stay between 4 to 5 days. Data on harms were inconsistently reported and heterogeneous, making estimates of harm tentative and imprecise. Morbidity rates ranged between 5–15%, with mesh complications accounting for 0.5% of patients overall. No mortality was reported after any procedures in a total of 1044 patients. Although inconsistently reported, good or satisfactory outcome occurred in 83% (74–91%) of patients; 86% (20–97%) of patients reported improvements in constipation after laparoscopic ventral mesh rectopexy (LVMR). About 2–7% of patients developed anatomical recurrence. Patient selection was inconsistently documented. As most common indication, high grade rectal intussusception was corrected in 80–100% of cases after robotic or LVMR. Healing of prolapse‐associated solitary rectal ulcer syndrome occurred in around 80% of patients after LVMR.ConclusionEvidence supporting rectal suspension procedures is currently derived from poor quality studies. Methodologically robust trials are needed to inform future clinical decision making.
