Negative online consumer reviews: effects of different responses
Authors: Ullrich Sebastian , Brunner Christian Boris 
Published: March 2015

Purpose
– This paper aims to investigate the effects of different response options to a negative consumer review. When consumers buy online, they are often confronted with consumer reviews. A negative consumer review on an online shopping website may keep consumers from buying the product. Therefore, negative online consumer reviews are a serious problem for brands.

Design/methodology/approach
– In an online experiment of 446 participants, different response options towards a negative consumer review on an online shopping website were examined. The experimental data were analysed with linear regression models using product purchase intentions as the outcome variable.

Findings
– The results indicate that a positive customer review counteracts a negative consumer review more effectively than a positive brand response, whereas brand strength moderates this relationship. Including a reference to an independent, trusted source in a brand or a customer response is only a limited strategy for increasing the effectiveness of a response.

Research limitations/implications
– Additional research on other product categories and with subjects other than students is suggested to validate the findings. In future research, multiple degrees of the phrasing’s strength of the reference could be used.

Practical implications
– Assuming high quality products, brands should encourage their customers to write reviews. Strong brands can also reassure consumers by responding, whereas weak brands cannot.

Originality/value
– This research contributes to the online consumer reviews literature with new insights about the role of brand strength and referencing to an independent, trusted source.
Consumer engagement in online brand communities: a social media perspective
Authors: Dessart Laurence , Veloutsou Cleopatra , Morgan-Thomas Anna 
Published: March 2015

Purpose
– This paper aims to delineate the meaning, conceptual boundaries and dimensions of consumer engagement within the context of online brand communities both in term of the engagement with the brand and the other members of the online brand communities. It also explores the relationships of consumer engagement with other concepts, suggesting antecedents of engagement.

Design/methodology/approach
– Data are collected through semi-structured interviews with 21 international online brand community members, covering a variety of brand categories and social media platforms.

Findings
– This paper suggests that individuals are engaging in online communities in social network platforms both with other individuals and with brands. The study also identifies three key engagement dimensions (cognition, affect and behaviours). Their meaning and sub-dimensions are investigated. The paper further suggests key drivers, one outcome and objects of consumer engagement in online brand communities. These findings are integrated in a conceptual framework.

Research limitations/implications
– Further research should aim at comparing consumer engagement on different social media and across brand categories, as this study takes a holistic approach and does not focus on any particular category of brands or social media. Consumers’ views should also be evaluated against and compared with marketing managers’ understanding of consumer engagement.

Originality/value
– This paper contributes to the fast-growing and fragmented consumer engagement literature by refining the understanding of its dimensions and situating it in a network of conceptual relationships. It focusses on online brand communities in rich social media contexts to tap into the core social and interactive characteristics of engagement.
Positive and negative supervisor developmental feedback and task-performance
Authors: Zheng Xingshan , Diaz Ismael , Jing Yin , Chiaburu Dan S. 
Published: March 2015

Purpose– The purpose of this paper is to conceptualize, understand, and measure positive and negative aspects of supervisor developmental feedback (SDF) and investigate their relationships with task performance.Design/methodology/approach– In Study 1, common themes in SDF were identified and a set of SDF items were developed to capture the positive and negative SDF domain. Study 2 entailed the administration of the items to respondents to examine the dimensionality of the items through exploratory factor analysis. In Study 3, using confirmatory factor analysis we further examined the extent to which positive and negative developmental feedback (PSDF and NSDF) were conceptually distinct from each other and different from an existing general measure of supervisor feedback.Findings– Study 1 and Study 2 yielded evidence that positive and negative SDF are distinct yet related constructs. Positive SDF predicted employee task performance. The positive SDF by negative SDF interaction predicted task performance.Research limitations/implications– The authors provide criterion-related validity evidence by examining the predictive validity of positive and negative SDF on subordinate task performance (reported by supervisors). Future research should examine the role of positive and negative SDF in predicting job performance in other samples and cultural contexts and for other outcomes, including organizational citizenship.Originality/value– This research refines the SDF domain by identifying positive and negative domains of the SDF construct. The authors propose and test the joint influence of positive and negative SDF. The novel findings point to the importance of supervisors providing both positive and negative feedback to enhance performance.
E-government in the making: an actor network perspective
Authors: Cordella Antonio , Hesse Jakob 
Published: March 2015

Purpose
– This paper aims to introduce a new approach to the framing of e-government projects. It discusses e-government as a continuing process of interaction and change. The paper uses general concepts borrowed from actor–network theory (ANT) to highlight the on-going negotiation that is an endogenous characteristic of every e-government projects.

Design/methodology/approach
– The research builds on the findings of a case study. The case of the Akshaya e-government project in Kerala, India, is presented to offer an instance of the negotiation that occurs among the different actors involved and the consequent changes the project itself experiences.

Findings
– The paper shows that e-government initiatives are unstable and change over time, as they are cast in the dynamic interaction that occurs between the actors involved in the e-government project. It also suggests that the ANT is a valuable framework to study these dynamics.

Research limitations/implications
– Main contribution of the paper is the evidence that e-government projects should be studied in their making and not as a result of planned action and sequential evolutionary phases.

Practical implications
– The paper offers new insights for the planning, design and most importantly management of e-government projects.

Originality/value
– The paper contributes to the literature by shedding light on the importance of the dynamic interactions that shape the impact of information and communication technologies (ICTs) on government policies. The proposed framework is a basis for further theorisation with regards to the complexity underpinning the deployment of ICTs in the public sector.
The story of the sixth myth of open data and open government
Authors: Hellberg Ann-Sofie , Hedström Karin 
Published: March 2015

Purpose
– The aim of this paper is to describe a local government effort to realise an open government agenda. This is done using a storytelling approach.

Design/methodology/approach
– The empirical data are based on a case study. The authors participated in, as well as followed, the process of realising an open government agenda on a local level, where citizens were invited to use open public data as the basis for developing apps and external Web solutions. Based on an interpretative tradition, they chose storytelling as a way to scrutinise the competition process. In this paper, they present a story about the competition process using the story elements put forward by Kendall and Kendall (2012).

Findings
– The research builds on existing research by proposing the myth that the “public” wants to make use of open data. The authors provide empirical insights into the challenge of gaining benefits from open public data. In particular, they illustrate the difficulties in getting citizens interested in using open public data. Their case shows that people seem to like the idea of open public data, but do not necessarily participate actively in the data reuse process.

Research limitations/implications
– The results are based on one empirical study. Further research is, therefore, needed. The authors would especially welcome more studies that focus on citizens’ interest and willingness to reuse open public data.

Practical implications
– This study illustrates the difficulties of promoting the reuse of open public data. Public organisations that want to pursue an open government agenda can use these findings as empirical insights.

Originality/value
– This paper answers the call for more empirical studies on public open data. Furthermore, it problematises the “myth” of public interest in the reuse of open public data.
The sociologist and the state. An assessment of Pierre Bourdieu's sociology
Authors: Schinkel Willem 
Published: March 2015

AbstractThis paper provides an assessment of Pierre Bourdieu's sociology based on a reading of his posthumously published lectures on the state in Sur l'État. It argues that the state was a foundational element in Bourdieu's rendition of the symbolic order of everyday life. As such, the state becomes equally pivotal in Bourdieu's sociology, the applicability of which rests on the existence of the state, which stabilizes the social fields and their symbolic action that constitute the object of sociology. The state, which Bourdieu considers a ‘meta'‐ordering principle in social life, ensures that sociology has a well‐ordered object of study, vis‐à‐vis which it can posit itself as ‘meta‐meta’. The state thus functions as an epistemic guarantee in Bourdieu's sociology. A critical analysis of Bourdieu's sociology of the state offers the chance of a more fundamental overall assessment of Bourdieu's conception of sociology that has relevance for any critical sociological perspective that rests on the assumption of a meta‐social entity, such as the state in Bourdieu's work, as a final ordering instance.
Thermo‐stable semihard Gouda‐type cheese by combining homogenisation and microfiltration of cheese milk
Authors: Schenkel Philipp , Hinrichs Jörg 
Published: March 2015

Semihard Gouda‐type cheeses were manufactured at pilot scale using either homogenised milk or homogenised microfiltration retentate. For comparison, cheeses were produced from untreated milk as a Control. Thermo‐physical properties (flowability, stretchability, oiling‐off and browning) were analysed after 4 weeks of ripening. Homogenisation significantly altered the cheese properties, whereas the additional influence of milk pre‐concentration by MF was minor. Compared to the Control, homogenisation led to a significant reduction in flowability, stretchability, oiling‐off and browning. The homogenised fat globules act as active fillers, take part in the protein network and increase the network stability by enhancing protein–protein interactions.
On the Hospital Volume and Outcome Relationship: Does Specialization Matter More Than Volume?
Authors: Lee Kris C. L. , Sethuraman Kannan , Yong Jongsay 
Published: March 2015

ObjectiveTo evaluate the relationship between hospital volume and outcome by focusing on alternative measures of volume that capture specialization and overall throughput of hospitals.Data Sources/Study SettingHospital administrative data from the state of Victoria, Australia; data contain 1,798,474 admitted episodes reported by 135 public and private acute‐care hospitals.Study DesignThis study contrasts the volume–outcome relationship using regression models with different measures of volume; two‐step and single‐step risk‐adjustment methods are used.Data Collection/Extraction MethodsThe sample is restricted to ischemic heart disease (IHD) patients (ICD‐10 codes: I20–I25) admitted during 2001/02 to 2004/05.Principal FindingsOverall hospital throughput and degree of specialization display more substantive implications for the volume–outcome relationship than conventional caseload volume measure. Two‐step estimation when corrected for heteroscedasticity produces comparable results to single‐step methods.ConclusionsDifferent measures of volume could lead to vastly different conclusions about the volume–outcome relationship. Hospital specialization and throughput should both be included as measures of volume to capture the notion of size, focus, and possible congestion effects.
Molecular characterization and diversity analysis of bacterial communities associated with Dialeurolonga malleswaramensis (Hemiptera: Aleyrodidae) adults using 16S rDNA amplicon pyrosequencing and FISH
Authors: Pandey Neeti , Rajagopal Raman 
Published: March 2015

AbstractDialeurolonga malleswaramensis Sundararaj (Hemiptera: Aleyrodidae) is a phytophagous sap sucking insect. It infests Polyalthia longifolia, an important avenue tree of India, effective in alleviating noise pollution and having immense medicinal importance. Samples of this insect were collected from Polyalthia longifolia. The cytochrome c oxidase subunit I gene (mtCO1) helped in the molecular characterization of the insect. This study reports the bacterial diversity in D. malleswaramensis adults by high throughput 16S rDNA amplicon pyrosequencing. The major genera identified were Portiera and Arsenophonus. Other bacterial genera detected were uncultured alpha proteobacterium, Sphingopyxis and Methylobacterium. We also employed fluorescence in situ hybridization (FISH) in whole mount samples to confirm the presence of dominant endosymbionts Portiera and Arsenophonus to the bacteriocyte of D. malleswaramensis. This study concludes that combining techniques like 16S rDNA amplicon pyrosequencing and FISH reveal both dominant and rare bacteria. The data also predict the evolutionary position of this pest with respect to other whitefly species using a mitochondrial marker.

SummaryAimsThe 2012 American College of Chest Physician Evidence‐Based Management of Anticoagulant Therapy guidelines suggest an international normalized ratio (INR) testing interval of up to 12 weeks, rather than every 4 weeks, for patients with consistently stable INRs while taking vitamin K antagonists. We aimed to examine the feasibility of extended‐interval follow‐up in a real‐world setting.MethodsPatients receiving stable warfarin therapy for ≥12 weeks at baseline began extended‐interval follow‐up with visits occurring at 6 weeks, 14 weeks, and every 12 weeks thereafter to a maximum of 68 weeks or until they were no longer suitable for extended‐interval follow‐up. A single INR excursion >0.3 from goal was permitted if a reversible precipitating factor was identified and the INR was expected to return to goal without dose adjustment. The primary outcome was the proportion of patients completing all study follow‐up visits.ResultsOf 48 patients enrolled, 47 had evaluable data. The most common indication for anticoagulation was atrial fibrillation/flutter (53.2%). At baseline, mean prior warfarin treatment duration was 6.7 ± 6 years and median number of weeks on a stable regimen was 24 weeks (IQR, 19–37.5). Eleven patients (23%) completed all study follow‐up visits, whereas 17 (36%) did not maintain a stable INR past the 14‐week follow‐up.ConclusionA large proportion of patients with previously stable (≥3 months) INRs were not able to maintain stable INRs during extended‐interval follow‐up. More research is needed to identify patient characteristics predictive of success with extended‐interval follow‐up prior to broad implementation.

Published: March 2015

SummaryCatheter‐based renal denervation (RDN) is a novel invasive approach in the treatment of resistant hypertension. It is considered a minimally invasive and safe procedure which, as shown by initial experimental and clinical trials, is able not only to reduce blood pressure but also to modify its risk factors by modulation of autonomic nervous system. Recently published results of a randomized Symplicity HTN‐3 trial, which failed to demonstrate RDN‐induced reduction of blood pressure at six months, decreased the initial enthusiasm regarding RDN and raised a question about real efficacy of this procedure. Nevertheless, still there are some other conditions characterized by increased sympathetic tone such as heart failure, atrial fibrillation, or ventricular arrhythmias that may benefit from RDN. Furthermore, novel therapeutical approach toward RDN using adapted electrophysiological or new specially designed electrodes may improve effectiveness of RDN procedure.

Statistical Inference for Curved Fibrous Objects in 3D – Based on Multiple Short Observations of Multivariate Autoregressive Processes
Authors: Gaiselmann Gerd , Kulik Rafal , Schmidt Volker 
Published: March 2015

SummaryThis paper deals with statistical inference on the parameters of a stochastic model, describing curved fibrous objects in three dimensions, that is based on multivariate autoregressive processes. The model is fitted to experimental data consisting of a large number of short independently sampled trajectories of multivariate autoregressive processes. We discuss relevant statistical properties (e.g. asymptotic behaviour as the number of trajectories tends to infinity) of the maximum likelihood (ML) estimators for such processes. Numerical studies are also performed to analyse some of the more intractable properties of the ML estimators. Finally the whole methodology, i.e., the fibre model and its statistical inference, is applied to appropriately describe the tracking of fibres in real materials.

AbstractPurposeThis study aimed to evaluate the angiogenesis‐related factors of the vascular endothelial growth factor (VEGF) family in the aqueous humour of patients with neovascular glaucoma (NVG).MethodsThis study involved 22 eyes of 22 patients with advanced NVG requiring antiglaucomatous surgery and 20 control subjects with cataracts. The NVG eyes received an intravitreal injection of ranibizumab (IVR) treatment before antiglaucomatous surgery. Aqueous humour and blood were collected at the time of IVR and cataract surgery. Protein concentration of VEGF‐A, VEGF‐B and placenta growth factor (PlGF) in aqueous humour and plasma was determined by ELISA tests.ResultsThe mean concentration (standard deviation) of VEGF‐A and PlGF in the aqueous humour of patients with NVG were 3037 (2387) pg/ml and 1078 (712) pg/ml, respectively; both were significantly higher than the control group (both p < 0.001). However, levels of VEGF‐A and PlGF in the serum of NVG and control subjects remained low. High concentrations of VEGF‐A were closely correlated with high levels of PlGF in patients with NVG (r = 0.593, p = 0.004). Concentrations of VEGF‐B in aqueous humour and serum remained unchanged (p > 0.05).ConclusionThere were high concentrations of angiogenesis factors of the VEGF family, with the exception of VEGF‐B, in the aqueous humour of patients with NVG, and there was a positive correlation between VEGF‐A and PlGF. High PlGF levels in patients with NVG may provide another potential target for treatment of NVG.
Bayesian function‐on‐function regression for multilevel functional data
Authors: Meyer Mark J. , Coull Brent A. , Versace Francesco , Cinciripini Paul , Morris Jeffrey S. 
Published: March 2015

SummaryMedical and public health research increasingly involves the collection of complex and high dimensional data. In particular, functional data—where the unit of observation is a curve or set of curves that are finely sampled over a grid—is frequently obtained. Moreover, researchers often sample multiple curves per person resulting in repeated functional measures. A common question is how to analyze the relationship between two functional variables. We propose a general function‐on‐function regression model for repeatedly sampled functional data on a fine grid, presenting a simple model as well as a more extensive mixed model framework, and introducing various functional Bayesian inferential procedures that account for multiple testing. We examine these models via simulation and a data analysis with data from a study that used event‐related potentials to examine how the brain processes various types of images.
Editorial: Learning design, teacher inquiry into student learning and learning analytics: A call for action
Authors: Mor Yishay , Ferguson Rebecca , Wasson Barbara 
Published: March 2015

AbstractThis special issue deals with three areas. Learning design is the practice of devising effective learning experiences aimed at achieving defined educational objectives in a given context. Teacher inquiry is an approach to professional development and capacity building in education in which teachers study their own and their peers' practice. Learning analytics use data about learners and their contexts to understand and optimise learning and the environments in which it takes place. Typically, these three—design, inquiry and analytics—are seen as separate areas of practice and research. In this issue, we show that the three can work together to form a virtuous circle. Within this circle, learning analytics offers a powerful set of tools for teacher inquiry, feeding back into improved learning design. Learning design provides a semantic structure for analytics, whereas teacher inquiry defines meaningful questions to analyse.
