Consumer response to private label brands’ negative publicity: a relational effect on retailer’s store image
Authors: Gendel-Guterman Hanna , Levy Shalom 
Published: May 2017

PurposeThis study aims to examine the effect of private label brand (PLB) products’ negative publicity (NP) events on PLB general image and retailer’s store image, because of the suggested interdependency between retailer’s store image and PLB image.Design/methodology/approachThree empirical studies were conducted to test the NP effect – Studies 1 and 2, respectively; and test the occurrence of moderate and extreme NP events regarding the functional PLB product category. Study 3 replicates prior studies conducted on the hedonic product category. In these studies, participants were randomly assigned to treatment and control groups. The studies use factor analysis methods followingt-tests and paths analyses, using structural equation modeling (SEM).FindingsFindings show that both moderate and extreme NP have an influence on the PLB’s image dimensions. These effects “spilled over” to the entire range of PLB products, regardless of the category of the damaged product. Regarding retailer’s store image, the effect of NP was retained in the product-related image context and did not exceed that of the store-related image. However, in relation to functional products, when NP is very extreme, the effect on PLB image exceeds that of retailer’s store image.Practical implicationsRetailers should invest more efforts in their PLB product selection, quality maintenance and supervision to eliminate potential damage from events related to their PLB products.Originality/valueThe originality of this study is in the association of two streams of research: NP effects and the relationship between PLB image and retailer’s store image.
Building a comprehensive model to investigate factors behind switching intention of high-technology products
Authors: Msaed Cristelle , Al-Kwifi Sam O. , Ahmed Zafar U. 
Published: May 2017

PurposeThe purpose of this study is to determine the factors that underpin consumer switching intention in the smartphone industry. Most of the literature on brand switching uses conventional models that lack the ability to explain this behavior for high-technology products. Such products have unique characteristics that make the switching process more challenging from the consumer perspective.Design/methodology/approachThe proposed model is built based on the related theories that consider the distinctive aspects of high-technology products. Furthermore, two variables “relative advantage of product features” and “company innovativeness” are introduced for the first time to evaluate consumer attitude to switch a high-technology product. The smartphone industry was selected to test the proposed model, where an online survey was sent to Apple and Samsung users.FindingsThe results confirm the expectation that perceived product usefulness, perceived ease of use and relative advantage of product features are the major factors driving the intention of users to switch, whereas subjective norms have limited impact. The financial cost of switching is the main barrier to consumers’ decision to switch to a new technology. The pleasure consumers feel toward their brand and the other brand is positively associated with their attitude toward switching.Research limitations/implicationsThis research contributes to the literature on brand switching by introducing a comprehensive model that explains consumer switching behavior of high-technology products. Research findings would allow managers to draft better marketing strategies to improve consumer brand awareness.Originality/valueThe majority of literature on brand switching uses simple models to explain consumer behavior. This study is the first attempt to build a comprehensive model that considers the characteristics of high-technology products and how they shape consumer behavior during the decision-making process.
Pedestrian navigation system using MEMS sensors for heading drift and altitude error correction
Authors: Tian Xiaochun , Chen Jiabin , Han Yongqiang , Shang Jianyu , Li Nan 
Published: May 2017

Purpose
This study aims to design an optimized algorithm for low-cost pedestrian navigation system (PNS) to correct the heading drift and altitude error, thus achieving high-precise pedestrian location in both two-dimensional (2-D) and three-dimensional (3-D) space.

Design/methodology/approach
A novel heading correction algorithm based on smoothing filter at the terminal of zero velocity interval (ZVI) is proposed in the paper. This algorithm adopts the magnetic sensor to calculate all the heading angles in the ZVI and then applies a smoothing filter to obtain the optimal heading angle. Furthermore, heading correction is executed at the terminal moment of ZVI. Meanwhile, an altitude correction algorithm based on step height constraint is proposed to suppress the altitude channel divergence of strapdown inertial navigation system by using the step height as the measurement of the Kalman filter.

Findings
The verification experiments were carried out in 2-D and 3-D space to evaluate the performance of the proposed pedestrian navigation algorithm. The results show that the heading drift and altitude error were well corrected. Meanwhile, the path calculated by the novel algorithm has a higher match degree with the reference trajectory, and the positioning errors of the 2-D and 3-D trajectories are both less than 0.5 per cent.

Originality/value
Besides zero velocity update, another two problems, namely, heading drift and altitude error in the PNS, are solved, which ensures the high positioning precision of pedestrian in indoor and outdoor environments.
A survey of liveness detection methods for face biometric systems
Authors: Xin Yang , Liu Yi , Liu Zhi , Zhu Xuemei , Kong Lingshuang , Wei Dongmei , Jiang Wei , Chang Jun 
Published: May 2017

Purpose
Biometric systems are widely used for face recognition. They have rapidly developed in recent years. Compared with other approaches, such as fingerprint recognition, handwriting verification and retinal and iris scanning, face recognition is more straightforward, user friendly and extensively used. The aforementioned approaches, including face recognition, are vulnerable to malicious attacks by impostors; in such cases, face liveness detection comes in handy to ensure both accuracy and robustness. Liveness is an important feature that reflects physiological signs and differentiates artificial from real biometric traits. This paper aims to provide a simple path for the future development of more robust and accurate liveness detection approaches.

Design/methodology/approach
This paper discusses about introduction to the face biometric system, liveness detection in face recognition system and comparisons between the different discussed works of existing measures.

Originality/value
This paper presents an overview, comparison and discussion of proposed face liveness detection methods to provide a reference for the future development of more robust and accurate liveness detection approaches.

Published: May 2017

Purpose
The purpose of this paper is to design a current transformer model based on the principle of B-dot. It can reflect the change of transmission line current and meet the requirement of automation and intelligence for current measurement in power system.

Design/methodology/approach
In this paper, a new type of current transformer is designed on the principle of B-dot, which has the structure of the inverse series of planar air core coils and the form of printed circuit board (PCB). With this structure, the current transformers can induce magnetic field quite well. The finite element simulation for the current transformer with n layers structure is conducted in the Maxwell, which help to optimize the design of the current transformer.

Findings
By setting up the experimental platform, the experiment of the current transformer is carried out. The results of the test show that the measurement accuracy can satisfy the requirement of measurement. Besides, the new current transformer has good transient characteristics and can meet the needs of the development of smart grid.

Originality value
The new type of current transformer is based on the principle of B-dot, which is designed with a new type of non-contact PCB hollow coil current transformer. It has no iron core, no ferromagnetic effect and the phenomenon of ferromagnetic resonance. It has great progress in its insulation performance, volume and bandwidth response. In addition, the planar hollow coil of the inverse series structure can make the structure more accurate.

Published: May 2017

Purpose
The purpose of this paper is to design and fabricate a three-dimensional (3D) bionic airflow sensing array made of two multi-electrode piezoelectric metal-core fibers (MPMFs), inspired by the structure of a cricket’s highly sensitive airflow receptor (consisting of two cerci).

Design/methodology/approach
A metal core was positioned at the center of an MPMF and surrounded by a hollow piezoceramic cylinder. Four thin metal films were spray-coated symmetrically on the surface of the fiber that could be used as two pairs of sensor electrodes.

Findings
In 3D space, four output signals of the two MPMFs arrays can form three “8”-shaped spheres. Similarly, the sensing signals for the same airflow are located on a spherical surface.

Originality/value
Two MPMF arrays are sufficient to detect the speed and direction of airflow in all three dimensions.
Metal Contents, Bioaccumulation, and Health Risk Assessment in Wild Edible Boletaceae Mushrooms
Authors: Sun Liping , Chang Weidan , Bao Changjun , Zhuang Yongliang 
Published: May 2017

AbstractEight wild edible Boletaceae mushrooms (227 samples) and their soils were collected from 40 locations, Yunnan province, China. Four essential metals (Fe, Mg, Zn, and Cu) and 2 toxic metals (Pb and Cd) were determined. The results showed that Boletaceae mushrooms have abundance of 4 essential metals. The highest Pb mean value was 0.70 mg/kg DW, lower than legal limits, but Cd contents significantly exceeded legal limits. Generally, bioconcentration factor (BCF) indicated that Zn and Cu were easily bioaccumulated by mushrooms. However, the BCFCd of Boletus griseus reached to 6.40. Target hazard quotients showed Cd was the main risk metal in Boletaceae mushrooms. The metal compositional variability and the similarity of metal contents were further determined by principal component analysis. Regression model analysis indicated that Cd contents in mushrooms were positively correlated with soil Cd contents, and negatively correlated with soil pH, except for the samples of Boletus bicolor.

Published: May 2017

OBJECTIVEAcute‐on‐chronic liver failure (ACLF) is a distinct syndrome that develops in patients with cirrhosis and acute decompensation (AD). This study focused on the precipitating events (PEs) of hepatitis B virus (HBV)‐related cirrhotic patients diagnosed as ACLF based on the Chronic Liver Failure Consortium organ failure (CLIF‐C OF) score.METHODSHospitalized patients with HBV‐related cirrhosis and AD were retrospectively included. The patients’ characteristics, laboratory test results, PEs, CLIF‐C OF score and short‐term prognosis were evaluated.RESULTSOf the 890 patients enrolled 300 (33.7%) were diagnosed as ACLF and 590 (66.3%) without ACLF. ACLF patients had a higher incidence of PEs than those without ACLF. The ACLF patients were more prone to having PEs of bacterial infection (P < 0.001), HBV reactivation (P < 0.001), active alcoholism (P = 0.036) and superimposed hepatitis virus infection (P = 0.031), whereas portal vein thrombosis (P = 0.002) were less common in the non‐ACLF group. ACLF patients with the top four single PEs had diverse types of organ failures. However, they shared a similar short‐term prognosis. While in patients without PEs the ACLF group had higher systemic inflammation and deterirated outcomes compared with the non‐ACLF group.CONCLUSIONS
PEs of bacterial infection, HBV reactivation, active alcoholism and superimposed hepatitis virus infection, but not GI hemorrhage or portal vein thrombosis, were risk factors for ACLF. There may be two types of patients with ACLF based on the differences in the clinical manifestation of the disease.
Attracting Prospective Professional Accountants Before and After the CPA Merger in Canada
Authors: Brouard François , Bujaki Merridee , Durocher Sylvain 
Published: May 2017

AbstractAs part of the unification of the Canadian accounting profession, a lot of effort has been devoted to organizational structures and systems. In these times of change, recruitment of prospective professional accountants remains an important factor for the Canadian and international development of the profession. In this paper, we explore professional accountants’ recruitment by accounting associations in Ontario before (CA, CGA, CMA) and after (CPA) the merger of the three professional accounting associations. We use a legitimacy framework to make sense of the recruitment website content of each association. We find, in the post‐merger period, that the CPA profession adopts a more passive approach to legitimacy management, focusing mainly on exchange aspects of legitimacy, whereas prior to the merger a wider range of legitimacy management strategies were deployed by the predecessor associations. Important implications ensuing from our study are discussed.
Nicotine self‐administration reverses cognitive deficits in a rat model for schizophrenia
Authors: Waterhouse Uta , Brennan Katharine A. , Ellenbroek Bart A. 
Published: May 2017

AbstractHigh comorbidity between schizophrenia and tobacco addiction has been well established. Explanatory theories include nicotine as a cognitive enhancer ameliorating symptoms of schizophrenia and underlying shared substrates increasing susceptibility to addiction in these individuals. To test these non‐mutually exclusive theories, the maternal immune activation (MIA) model was utilized. To this end, pregnant Sprague Dawley rats were subcutaneously injected with a bacterial endotoxin, lipopolysaccharide (0.5 mg/kg), on gestation days 10 and 11. Selective attention and working memory in adult male offspring were subsequently assessed using the latent inhibition and delayed non‐matching to sample paradigms both before and after nicotine or saline self‐administration. MIA led to deficits in both latent inhibition and delayed non‐matching to sample in male offspring. Further, these animals showed a small but significantly increased responding for nicotine during self‐administration acquisition, although there was no difference in dose–response effect or in progressive ratio testing. However, nicotine, but not saline self‐administration, significantly ameliorated the cognitive deficits induced by MIA. While the male offspring of mothers prenatally exposed to lipopolysaccharide was only slightly more sensitive to the reinforcing effects of nicotine, after self‐administration, the MIA‐induced cognitive deficits significantly improved. These data lend support for the self‐medication hypothesis of schizophrenia.
Multi-subgroup Gene Screening Using Semi-parametric Hierarchical Mixture Models and the Optimal Discovery Procedure: Application to a Randomized Clinical Trial in Multiple Myeloma
Authors: Matsui Shigeyuki , Noma Hisashi , Qu Pingping , Sakai Yoshio , Matsui Kota , Heuck Christoph , Crowley John 
Published: May 2017

SummaryThis article proposes an efficient approach to screening genes associated with a phenotypic variable of interest in genomic studies with subgroups. In order to capture and detect various association profiles across subgroups, we flexibly estimate the underlying effect size distribution across subgroups using a semi-parametric hierarchical mixture model for subgroup-specific summary statistics from independent subgroups. We then perform gene ranking and selection using an optimal discovery procedure based on the fitted model with control of false discovery rate. Efficiency of the proposed approach, compared with that based on standard regression models with covariates representing subgroups, is demonstrated through application to a randomized clinical trial with microarray gene expression data in multiple myeloma, and through a simulation experiment.
An investigation of the mechanism underlying teacher aggression: Testing I3 theory and the General Aggression Model
Authors: Montuoro Paul , Mainhard Tim 
Published: May 2017

BackgroundConsiderable research has investigated the deleterious effects of teachers responding aggressively to students who misbehave, but the mechanism underlying this dysfunctional behaviour remains unknown.AimsThis study investigated whether the mechanism underlying teacher aggression follows I3 theory or General Aggression Model (GAM) metatheory of human aggression. I3 theory explains exceptional, catastrophic events of human aggression, whereas the GAM explains common human aggression behaviours.SampleA total of 249 Australian teachers participated in this study, including 142 primary school teachers (Mdn [age] = 35–39 years; Mdn [years teaching] = 10–14 years; 84% female) and 107 secondary school teachers (Mdn [age] = 45–49 years; Mdn [years teaching] = 15–19 years; 65% female).MethodsParticipants completed four online self‐report questionnaires, which assessed caregiving responsiveness, trait self‐control, misbehaviour provocation, and teacher aggression.ResultsAnalyses revealed that the GAM most accurately captures the mechanism underlying teacher aggression, with lower caregiving responsiveness appearing to indirectly lead to teacher aggression via higher misbehaviour provocation and lower trait self‐control in serial, controlling for gender, age, years teaching, and current role (primary, secondary).ConclusionsThis study indicates that teacher aggression proceeds from ‘the person in the situation’. Specifically, lower caregiving responsiveness appears to negatively shape a teacher's affective, cognitive, and arousal states, which influence how they perceive and interpret student misbehaviour. These internal states, in turn, appear to negatively influence appraisal and decision processes, leading to immediate appraisal and impulsive actions. These results raise the possibility that teacher aggression is a form of countertransference.
Off the Waterfront: The Long‐Run Impact of Technological Change on Dockworkers
Authors: El‐Sahli Zouheir , Upward Richard 
Published: May 2017

AbstractWe investigate how individual workers and local labour markets adjust over a long time period to a discrete and plausibly exogenous technological shock, namely the introduction of containerization in the UK port industry. This technology, which was introduced rapidly between the mid‐1960s and the late‐1970s, had dramatic consequences for specific occupations within the port industry. Using longitudinal micro‐census data, we follow dockworkers over a 40‐year period and examine the long‐run consequences of containerization for patterns of employment, migration and mortality. The results show that the job guarantees negotiated by the unions protected dockworkers' employment until the guarantees were removed in 1989. A matched comparison of workers in comparable unskilled occupations reveals that, even after job guarantees were removed, dockworkers did not fare worse than the comparison group in terms of their labour market outcomes. Our results suggest that job guarantees provided a safety net which reduced the cost to workers of sudden technological change.

ObjectiveTo investigate biopsy complications and hospital admissions that could be reduced by the use of European Randomized Study of Screening for Prostate Cancer (ERSPC) risk calculators.Materials and MethodsAll biopsies performed in the Rotterdam section of the ERSPC between 1993 and 2015 were included. Biopsy complications and hospital admission data were prospectively recorded in questionnaires that were completed 2 weeks after biopsy. The ERSPC risk calculators 3 (RC3) and 4 (RC4) were applied to men attending the first and subsequent rounds of screening, respectively. Applying the predefined RC3/4 probability thresholds for prostate cancer (PCa) risk of ≥12.5% and high‐grade PCa risk ≥3%, we assessed the number of complications, admissions and costs that could be reduced by avoiding biopsies in men below these thresholds.ResultsA total of 10 747 biopsies with complete questionnaires were included. For these biopsies a complication rate of 67.9% (7294/10 747), a post‐biopsy fever rate of 3.9% (424/10747) and a hospital admission rate of 0.9% (92/10747) were recorded. The fever rate was found to be static over the years, but the hospital admission rate tripled from 0.6% (1993–1996) to 2.1% (2009–2015). Among 7704 biopsies which fit the criteria for RC3 or RC4, 35.8% of biopsies (2757/7704), 37.4% of complications (1972/5268), 39.4% of fever events (128/325) and 42.3% of admissions (30/71) could have been avoided by using one of the risk calculators. More complications could have been avoided if RC4 had been used and for more recent biopsies (2009–2015). Our findings show that 35.9% of the total cost of biopsies and complication treatment could have been avoided.ConclusionA significant proportion of biopsy complications, hospital admissions and costs could be reduced if biopsy decisions were based on ERSPC risk calculators instead of PSA only. This effect was most prominent in more recent biopsies and in men with repeated biopsies or screening.
