Omni-channel service failures and recoveries: refined typologies using Facebook complaints
Authors: Rosenmayer Anneliese , McQuilken Lisa , Robertson Nichola , Ogden Steve 
Published: February 2018

PurposeThis paper aims to present two updated typologies of service failures and recoveries in the omni-channel context. These typologies are based on customer complaints and recoveries collected from the corporate Facebook pages of four omni-channel department stores, two operating in Australia and two in the UK.Design/methodology/approachA document review is used of 400 customer complaints and recoveries. Content analysis is used to condense the Facebook data into categories of failures and recoveries.FindingsCustomer complaints on Facebook were triggered by a multitude of varying failures in the omni-channel context, given that it is the service brand that customers are experiencing, not just retail channels. The most prevalent failures were “bricks and mortar” shopping, delivery, marketing activities including communications and pricing, quality of goods and customer service. For service recoveries on Facebook, the four-dimensional justice framework appears valid.Research limitations/implicationsStudy limitations include potentially missing details about the nature of the service failures and recoveries, including customer satisfaction with service recovery.Practical implicationsThe typologies offer guidance to omni-channel retailers by showing the range of online and offline situations, including those unrelated to actual transactions that trigger customer complaints on Facebook and the tactics of recovering.Originality/valueThe authors contribute to the service domain by updating failure and recovery typologies to reflect the emerging omni-channel context, jointly exploring failures and recoveries on Facebook and applying a four-dimensional justice framework for recoveries on Facebook.
Motivating service employee creativity: regulatory focus and emotional labour
Authors: Geng Zizhen , Li Caifeng , Bi Kejia , Zheng Haiping , Yang Xia 
Published: February 2018

PurposeThe purpose of this paper is to advance our understanding of the roles that service employees’ responses to high job demands play in service innovation, by examining the effects that service employees’ motivational orientation in self-regulation (regulatory focus) and their emotional labour strategy have on their creativity.Design/methodology/approachBy integrating regulatory focus theory and emotion regulation theory, the authors developed a theoretical model to propose the links between promotion and prevention regulatory foci, different emotional labour strategies and frontline employee creativity. The research hypotheses were tested using hierarchical linear model based on data collected from 304 frontline employees and 72 supervisors in 51 restaurants.FindingsThe results showed that promotion focus was positively related to frontline employee creativity while prevention focus was negatively related to it. In addition, both emotional labour strategies (deep acting and surface acting) mediated the effect of promotion focus on frontline employee creativity. Surface acting mediated the effect of prevention focus on frontline employee creativity.Originality/valueThis is the first research conducted to explain, from a self-regulatory perspective, the influence that is exerted on service employees’ service innovation by their responses to high job demands. The findings identify the effects that service employees’ promotion focus or prevention focus in self-regulation have on their creativity, and the data unravel the role of emotional labour strategy as the mediating mechanism that explains the influence of regulatory focus on service employee creativity. On the basis of the findings, managerial directions are offered with regard to managing service employees’ regulatory focus and emotional labour, with a view to enhancing the creativity and innovation within a service organisation.
Looking for info? Understanding ethical consumer information management using a diary approach
Authors: Papaoikonomou Eleni , Valor Carmen , Ginieis Matias 
Published: February 2018

Purpose
Although the role of information has been previously studied in the ethical consumer literature, practices related to information searches and interpretation have not been fully examined in relation to ethical consumption. The purpose of this paper is to explore the search and use of information by ethically oriented consumers in order to understand the problems involved in this process, and how ethical consumers address them by adopting a number of practices.

Design/methodology/approach
Using a qualitative approach and diaries, the paper explores how consumers carry out their informational search and interpretation over an 11-week period.

Findings
First, insights are provided about the specifics of information search and the contexts, timing and use of information. Second, the information management practices used by participants to navigate the problems they encounter are identified. These practices are discussed in relation to the maximizing vs optimizing approach adopted by the participants.

Practical implications
New technologies, such as mobile applications and geo-localization, could overcome some of the problems inherent to information searches identified in this study. The use of social networks may also prove particularly interesting for companies and NGOs that target ethically oriented consumers.

Originality/value
Information search and the use and interpretation of information are part of the efforts undertaken by ethical consumers, but they have not been the focus of past research. This study provides empirical evidence on consumer practices employed to circumvent the problems found in a context of information asymmetries, and the gradual development of consumer skills in relation to ethical information searches and management. It shows how information search and management shapes the practice of ethical consumption.
New results on the predictive value of crude oil for US stock returns
Authors: Brigida Matt 
Published: February 2018

Purpose
The purpose of this study is to clarify the nature of the predictive relationship between crude oil and the US stock market, with particular attention to whether this relationship is driven by time-varying risk premia.

Design/methodology/approach
The authors formulate the predictive regression as a state-space model and estimate the time-varying coefficients via the Kalman filter and prediction-error decomposition.

Findings
The authors find that the nature of the predictive relationship between crude oil and the US stock market changed in the latter half of 2008. After mid-2008, the predictive relationship switched signs and exhibited characteristics which make it much more likely that the predictive relationship is due to time-varying risk premia rather than a market inefficiency.

Originality/value
The authors apply a state-space approach to modeling the predictive relationship. This allows one to watch the evolution of the predictive relationship over time. In particular, the authors identify a dramatic shift in the relationship around August 2008. Prior research has not been able to identify shifts in the relationship.
Order book microstructure and policies for financial stability
Authors: Biondo Alessio Emanuele 
Published: February 2018

PurposeThe purpose of this paper is two-fold: first, to introduce an innovative model of financial order book, less simplified than the existing literature and still able to replicate all statistical features of true markets; second, to simulate realistically the effects of policies aimed to reduce the instability of financial markets.Design/methodology/approachThe paper is based on an agent-based model and the applied methodology is the computational simulation.FindingsThe policymaker can actively reduce the instability of financial market by means of policies aimed to increase the heterogeneity of investors, both in terms of the behavioral attitude for market participation and of the differentiation of opinions; favor investors who show insensibility with regard to market information; limit the allowed number of counterparts for any market order; reduce the time validity of orders; and maintain flexibility and efficient bargaining, reduce transaction costs and avoid Tobin taxes.Research limitations/implicationsIn future research, an opinion dynamics engine within a clustered community network will be embedded.Practical implicationsIndeed, the obtained results are policy rules which could be immediately applied.Originality/valueThe order book model contained in the paper is completely new, innovative and original. Innovativeness is based on a reduced number of simplifying assumptions. The realism of the presented mechanism is higher than in other existing models. The value of the model is high because of several factors. From the scientific point of view, it constitutes the reliable framework on which many other papers will be based: it is the core center of future research. From the policymaker’s point of view, it represents a credible tool for policy hypotheses testing.
Managerial implications of off-balance sheet items in community banks
Authors: Mckee Gregory , Kagan Albert 
Published: February 2018

Purpose
Community banks were affected distinctly by changes in banking regulation in the 1990s when compared with large commercial banks. These banks offer non-traditional finance items, presumably to compete with these financial institutions. This study aims to examine the importance of accounting for off-balance sheet (OBS) items when estimating the financial performance of community banks.

Design/methodology/approach
This study applies a two-stage analysis pathway that initially calculates X-efficiency scores as part of the overall cost structure and then deploys data envelopment analysis bootstrapping method for a second-stage ordinary least square model.

Findings
Study findings indicate that failure to include OBS items in the X-efficiency calculation for community banks understates the efficiency performance of these banks. Furthermore, results indicate that factors internal and external to the community bank affect X-efficiency. Increases in OBS items are associated with growth in assets and growth in net non-interest income. Therefore, OBS items become an attractive alternative source of income and a mechanism for expanding output with the same volume of inputs. In addition, OBS items allow the largest community banks to deleverage their balance sheet, whereas the smallest community banks still emphasize on traditional lending products and benefit from existing equity. Also, larger banks may be using OBS items as a mechanism to isolate their performance from macroeconomic fluctuations.

Research limitations/implications
Research limitations include a reduced number of community banks as consolidation accelerates partly because of compliance concerns.

Practical implications
The approach used supports a series of community bank managerial approaches that may be adopted by management.

Originality/value
The results of this study show several reasons why community banks may have managerial incentives to include OBS items. As observed by Gilbert et al. (2013), community banks are adjusting their product line so as to operate efficiently. Community banks must provide a product line which provides margin and meets customer needs at a profit to the firm. OBS items allow existing staff to provide funds without additional equity requirements from the balance sheets. The increase in OBS activities may signal the perception that the associated interest income is less risky and less costly than other alternatives, including adopting technologies to diversify traditional loan product offerings. As community banks tend to have lower default rates than their larger counterparts, the most likely explanation is that the OBS interest risk is more attractive than compliance or development of mechanisms to offer a broader suite of traditional loan products.
Multi-modal haptic image recognition based on deep learning
Authors: Han Dong , Nie Hong , Chen Jinbao , Chen Meng , Deng Zhen , Zhang Jianwei 
Published: February 2018

Purpose
This paper aims to improve the diversity and richness of haptic perception by recognizing multi-modal haptic images.

Design/methodology/approach
First, the multi-modal haptic data collected by BioTac sensors from different objects are pre-processed, and then combined into haptic images. Second, a multi-class and multi-label deep learning model is designed, which can simultaneously learn four haptic features (hardness, thermal conductivity, roughness and texture) from the haptic images, and recognize objects based on these features. The haptic images with different dimensions and modalities are provided for testing the recognition performance of this model.

Findings
The results imply that multi-modal data fusion has a better performance than single-modal data on tactile understanding, and the haptic images with larger dimension are conducive to more accurate haptic measurement.

Practical implications
The proposed method has important potential application in unknown environment perception, dexterous grasping manipulation and other intelligent robotics domains.

Originality/value
This paper proposes a new deep learning model for extracting multiple haptic features and recognizing objects from multi-modal haptic images.
Transcriptional profiles of pulmonary innate immune responses to isogenic antibiotic‐susceptible and multidrug‐resistant Pseudomonas aeruginosa
Authors: Tam Vincent H. , Pérez Cynthia , Ledesma Kimberly R. , Lewis Russell E. 
Published: February 2018

ABSTRACTThe virulence of an isogenic pair of Pseudomonas aeruginosa strains was studied under similar experimental conditions in two animal infection models. The time to death was significantly longer for the multidrug resistant (MDR) than the wild‐type strain. The transcriptional profiles of 84 innate immune response genes in the lungs of immune competent Balb/C mice were further compared. Significantly weaker expression of genes involved in production of soluble pattern recognition receptor and complement were observed in animals infected with the MDR strain. Altered patterns of innate immune system activation may explain the attenuated virulence in MDR bacteria.
Gcn5‐dependent histone H3 acetylation and gene activity is required for the asexual development and virulence of Beauveria bassiana
Authors: Cai Qing , Wang Juan‐Juan , Fu Bo , Ying Sheng‐Hua , Feng Ming‐Guang 
Published: February 2018

SummaryGcn5 is a core histone acetyltransferase that catalyzes histone H3 acetylation on N‐terminal lysine residues in yeasts and was reported to catalyze H3K9/K14 acetylation required for activating asexual development in Aspergillus. Here, we report a localization of Gcn5 ortholog in the nucleus and cytoplasm of Beauveria bassiana, a fungal insect pathogen. Deletion of gcn5 led to hypoacetylated H3 at K9/14/18/27 and 97% reduction in conidiation capacity as well as severe defects in colony growth and conidial thermotolerance. Two master conidiation genes, namely brlA and abaA, were transcriptionally repressed to undetectable level in Δgcn5, but sharply upregulated in wild‐type, at the beginning time of conidiation. Based on chromatin immunoprecipitation, both DNA and acetylation levels of the distal and proximal fragments of the brlA promoter bound by acetylated H3K14 alone were upregulated in wild‐type, but not in Δgcn5, at the mentioned time. In Δgcn5, normal cuticle infection was abolished while virulence through cuticle‐bypassing infection was greatly attenuated, accompanied by drastically reduced activities of putative cuticle‐degrading enzymes, retarded dimorphic transition and transcriptional repression of associated genes. These findings unveil a novel mechanism by which Gcn5 activates asexual development pathway by acetylating H3K14 and regulates the virulence‐related cellular events in B. bassiana.
Medicare Payment Penalties and Safety Net Hospital Profitability: Minimal Impact on These Vulnerable Hospitals
Authors: Bazzoli Gloria J. , Thompson Michael P. , Waters Teresa M. 
Published: February 2018

ObjectiveTo examine relationships between penalties assessed by Medicare's Hospital Readmission Reduction Program and Value‐Based Purchasing Program and hospital financial condition.Data Sources/Study SettingCenters for Medicare and Medicaid Services, American Hospital Association, and Area Health Resource File data for 4,824 hospital‐year observations.Study DesignBivariate and multivariate analysis of pooled cross‐sectional data.Principal FindingsSafety net hospitals have significantly higher HRRP/VBP penalties, but, unlike nonsafety net hospitals, increases in their penalty rate did not significantly affect their total margins.ConclusionsSafety net hospitals appear to rely on nonpatient care revenues to offset higher penalties for the years studied. While reassuring, these funding streams are volatile and may not be able to compensate for cumulative losses over time.
A model‐based solution for observational errors in laboratory studies
Authors: Brost Brian M. , Mosher Brittany A. , Davenport Kristen A. 
Published: February 2018

AbstractMolecular techniques for detecting microorganisms, macroorganisms and infectious agents are susceptible to false‐negative and false‐positive errors. If left unaddressed, these observational errors may yield misleading inference concerning occurrence, prevalence, sensitivity, specificity and covariate relationships. Occupancy models are widely used to account for false‐negative errors and more recently have even been used to address false‐positive errors, too. Current modelling options assume false‐positive errors only occur in truly negative samples, an assumption that yields biased inference concerning detection because a positive sample could be classified as such not because the target agent was successfully detected, but rather due to a false‐positive test result. We present an extension to the occupancy modelling framework that allows false‐positive errors in both negative and positive samples, thereby providing unbiased inference concerning occurrence and detection, as well as reliable conclusions about the efficacy of sampling designs, handling protocols and diagnostic tests. We apply the model to simulated data, showing that it recovers known parameters and outperforms other approaches that are commonly used when confronted with observation errors. We then apply the model to an experimental data set on Batrachochytrium dendrobatidis, a pathogenic fungus that is implicated in the global decline or extinction of hundreds of amphibian species. The model‐based approach we present is not only useful for obtaining reliable inference when data are contaminated with observational errors, but also eliminates the need for establishing arbitrary thresholds or decision rules that have hidden and unintended consequences.
Voluntary Disclosure of Externally Sourced Technological Innovation and Managerial Opportunism: Evidence from the Korean Stock Market
Authors: Kim Kyung Soon , Lee Jin Hwon , Park Yun Woo 
Published: February 2018

AbstractThis study aims to investigate the information effect of voluntary disclosure of externally sourced technological innovation by type of technological innovation, namely, in‐bound technology transfer, out‐bound technology transfer, and technological alliance. Long‐term performance is lower for firms with lower quality accounting information and this effect is most evident in the disclosure of an in‐bound technology transfer. Further, low disclosure quality firms undergo a greater decline in long‐term performance after a seasoned equity offering following the disclosure of an in‐bound technology transfer than high disclosure quality firms. This relationship is more pronounced during a bear market than during a bull market.

Published: February 2018

ProblemGenital epithelial cells (GECs) line the mucosal surface of the female genital tract (FGT) and are the first cells that interface with both commensal microbiota and sexually transmitted pathogens. Despite the protective barrier formed by GECs, the FGT is a major site of HIV‐1 infection. This highlights the importance of studying the interaction of HIV‐1 and GECs.Method of studyUsing microarray analysis, we characterized the transcriptional profile of primary endometrial GECs grown in the presence or absence of physiological levels of E2 (10−9 mol/L) or P4 (10−7 mol/L) following acute exposure to HIV‐1 for 6 hours.ResultsAcute exposure of primary endometrial GECs to HIV‐1 resulted in the expression of genes related to inflammation, plasminogen activation, adhesion and diapedesis and interferon response. Interestingly, exposure to HIV‐1 in the presence of E2 and P4 resulted in differential transcriptional profiles, suggesting that the response of primary endometrial GECs to HIV‐1 exposure is modulated by female sex hormones.ConclusionThe gene expression signature of endometrial GECs indicates that the response of these cells may be key to determining host susceptibility to HIV‐1 and that sex hormones modulate these interactions. This study allows us to explore possible mechanisms that explain the hormone‐mediated fluctuation of HIV‐1 susceptibility in women.
The effect of superstitious thinking on psychosocial stress responses and perceived task performance
Authors: Lasikiewicz Nicola , Teo Wan Yee 
Published: February 2018

Previous research on superstitious belief, a subset of paranormal belief (Irwin, ), has suggested that people tend to invoke luck‐related superstitions in stressful situations as an attempt to gain an illusion of control over outcomes. Based on this, the current study examined whether luck‐related superstition, in the form of a “lucky” pen, could influence the psychological response to a psychosocial stressor. Participants (N = 114), aged between 17 and 59 years (M = 22.98, SD = 4.57) from James Cook University Singapore, were randomly assigned to one of four conditions: (a) no‐stress with no lucky pen; (b) no‐stress with a lucky pen; (c) stress with no lucky pen or; (d) stress with a lucky pen. The results revealed that participants provided with a lucky pen experienced lower state anxiety when exposed to the stressor. Further, participants provided with a lucky pen perceived their performance to be better than those without it. However, superstitious belief did not significantly change following exposure to stress. Taken together, the present findings add some support to the suggestion that belief in transferable luck may facilitate coping with a stressor. However, further research is needed to fully understand the mechanisms behind the potential benefits of superstitious belief.
