Authors: Spano-Szekely Lauraine , Winkler Anne , Waters Cathy , Dealmeida Susana , Brandt Kathy , Williamson Marsha , Blum Christina , Gasper Lori , Wright Fay
Published: September 2018

Background:

A 245-bed community hospital established patient fall prevention as its patient safety priority.

Problem:

The hospital's fall prevention program was not consistently effective. The baseline fall rate was 3.21, higher than the National Database of Nursing Quality Indicators' median of 2.91.

Approach:

An interprofessional fall prevention team evaluated the hospital's fall program using the evidence-based practice improvement model. A clinical practice guideline with 7 key practices guided the development of an individualized fall prevention program with interventions to address 4 fall risk categories and an algorithm to identify interventions. Interventions included nurse-driven mobility assessment, purposeful hourly rounding, and video monitoring for confused and impulsive fall-risk patients.

Outcomes:

The fall rate decreased to 1.14, with a 72% expense reduction based on decreased sitter usage.

Conclusions:

An interprofessional team successfully reduced falls with an evidence-based fall prevention program.

Authors: Schenk Elizabeth C. , Bryant Ruth A. , Van Son Catherine R. , Odom-Maryon Tamara
Published: September 2018

Background:

Patient safety–focused research may be strengthened by the inclusion of patients and family members in research design; yet, published methodologies for doing so are scarce.

Purpose:

This study engaged patients and families in research design of an intervention to increase patient/family engagement, with reduction of harm in hospitalized patients.

Methods:

The study design team convened a Patient Safety Advisory Panel to explore potential testable interventions to increase patient/family engagement with safety. They explored the preferred intervention, Speak Up-My Advocate for Patient Safety (MAPS), through multistakeholder focus groups.

Results:

Participants emphasized the importance of including patient/family when designing interventions. Regarding the Speak Up-MAPS intervention, perceptions from stakeholders were mixed, including the value and potential complexity, role confusion, and cost of the proposed advocate role.

Conclusion:

Intentional inclusion of the patient/family in research is important and practical. Both strengths and challenges of the proposed intervention were identified, indicating the need for further study.
Impact of Nurse Peer Review on a Culture of Safety
Authors: Herrington Cynthia R. , Hand Mikel W.
Published: September 2018

Background:

Nursing peer review (NPR) is essential in evaluating nursing practice. A common theme throughout the literature is that NPR holds nurses accountable for their practice.

Problem:

The nursing profession has struggled to conduct peer review consistently due to lack of a standardized framework.

Approach:

A NPR program was developed, implemented, and evaluated in a 355-bed acute care hospital in the Midwestern United States.

Outcomes:

A pre- and postdesign using the Agency for Healthcare Research and Quality Hospital Survey on Patient Safety Culture was used for evaluation. Paired t test results revealed statistically significant differences in group means for 2 questions: mistakes have led to positive changes here (P < .001, d = 1.31), and staff will freely speak up (P = .002, d = 0.67). Clinically significant differences in group means were noted for the remaining survey items.

Conclusions:

Implementation of an NPR program is a promising means to improve the culture of safety in health care institutions.
Parenting young people with complex regional pain syndrome: an analysis of the process of parental online communication
Authors: Navarro Kaedi , Wainwright Elaine , Rodham Karen , Jordan Abbie
Published: September 2018

Introduction:

Parenting a young person with complex regional pain syndrome (CRPS) is associated with high levels of parental distress and numerous emotional, informational, and practical challenges. To meet these challenges, parents seek others undergoing similar experiences, both in face to face and online forums.

Objectives:

The objective of this study was to conduct a qualitative analysis of online forum data to explore the process of parental forum communication regarding parenting a young person with CRPS in online spaces.

Methods:

A total of 107 forum posts relating to parenting a young person with CRPS were collected from 39 users across 2 public forums. Data were analyzed using thematic analysis.

Results:

Findings identified 2 themes: “the informal rules of exchanging and receiving network support” and “parents positioning themselves as experts.” The first theme highlighted the varied nature of support sought and provided by parents in addition to social rules associated with the negotiation of this support. The second theme represented an understanding of how parents presented themselves as experts in their young person's pain, both in relation to fellow parents and health care professionals.

Conclusion:

This study provided a novel insight into support and communicational exchanges between parents of young people with CRPS on online public forums. Findings identified the perceived usefulness of online spaces in terms of parents of young people with CRPS seeking and providing support. Further research can helpfully investigate how we might implement online peer mentoring to improve support further for parents.

Authors: Latimer Margot , Sylliboy John R. , MacLeod Emily , Rudderham Sharon , Francis Julie , Hutt-MacLeod Daphne , Harman Katherine , Finley Gordon Allen
Published: September 2018

Introduction:

Indigenous children and youth may be quiet about the way they express their pain and hurt which is in contrast to how health professionals are trained to assess it.

Objectives:

The aim was to understand how youth from 4 First Nation communities express pain using narratives and art-based methods to inform culturally appropriate assessment and treatment.

Methods:

This qualitative investigation used a community-based participatory action methodology to recruit 42 youth between 8 and 17 years of age to share their perspectives of pain using ethnographic techniques including a Talking Circle followed by a painting workshop. Physical pain perspectives were prominent in circle conversations, but emotional pain, overlapping with physical, mental, and spiritual pain perspectives, was more evident through paintings. Art themes include causes of pain and coping strategies, providing a view into the pain and hurt youth may experience. Youth were more comfortable expressing emotional and mental pain through their artwork, not sharing verbally in conversation.

Results:

Circle sessions and artwork data were themed using the Indigenous Medicine Wheel. Content of the circle conversations centered on physical pain, whereas paintings depicted mainly emotional pain (eg, crying or loneliness; 74% n = 31) with some overlap with physical pain (eg, injuries; 54%), mental pain (eg, coping strategies; 31%), and spiritual pain (eg, cultural symbols; 30%). Common threads included hiding pain, resilience, tribal consciousness, persistent pain, and loneliness.

Conclusion:

Once a safe space was created for First Nation youth, they provided a complex, culturally based understanding of the pain and coping experience from both an individual and community perspective. These engaging, culturally sensitive research methods provide direction for health providers regarding the importance of creating a safe space for young people to share their perspectives.

(Abstract included 248 words)

Although the relationship between schizophrenia spectrum disorder (SSD) and autism spectrum disorder (ASD) has long been debated, it has not yet been fully elucidated. To address this issue, we took advantage of dual (ASD and SSD) classifiers that discriminate patients from their controls based on resting state brain functional connectivity. An SSD classifier using sophisticated machine-learning algorithms that automatically selected SSD- specific functional connections was applied to Japanese datasets including adult patients with SSD in a chronic stage. We demonstrated good performance of the SSD classification for independent validation cohorts. The generalizability was tested by USA and European cohorts in a chronic stage, and one USA cohort including first episode schizophrenia. The specificity was tested by two adult Japanese cohorts of ASD and major depressive disorder, and one European cohort of attention-deficit hyperactivity disorder. The weighted linear summation of the classifier’s functional connections constituted the biological dimensions representing neural liability to the disorders. Our previously developed robust ASD classifier constituted the ASD dimension. Distributions of individuals with SSD, ASD and healthy controls were examined on the SSD and ASD biological dimensions. The SSD and ASD populations exhibited overlapping but asymmetrical patterns on the two biological dimensions. That is, the SSD population showed increased liability on the ASD dimension, but not vice versa. Furthermore, the two dimensions were correlated within the ASD population but not the SSD population. Using the two biological dimensions based on resting-state functional connectivity enabled us to quantify and visualize the relationships between SSD and ASD.

Polymorphism within the T cell receptor beta variable gene (TRBV) has been implicated in autoimmune disease and immuneCrelated adverse events (IRAEs) during immunotherapy. Previous efforts to evaluate TRBV polymorphism by whole genome sequencing (WGS) have been hampered by the repetitive nature of the TCRB locus. We present a novel longCamplicon TCRB repertoire sequencing approach to evaluate TRBV polymorphism from peripheral blood, which we use to identify TRBV allele haplotypes in 81 Caucasians.

Ricin toxin (RT) ranks at the top of the list of potential bioweapons of concern to civilian and military personnel alike due to its high potential for morbidity and mortality after inhalation. In non-human primates, aerosolized ricin triggers a severe acute respiratory distress characterized by perivascular and alveolar edema, neutrophilic infiltration, and severe necrotizing bronchiolitis and alveolitis. There are currently no approved countermeasures for ricin intoxication. In this report, we demonstrate the therapeutic potential of huPB10, a toxin-neutralizing humanized monoclonal antibody (MAb) against an immunodominant epitope on ricin’s enzymatic A chain (RTA). Five rhesus macaques that received intravenous huPB10 (10 mg/kg) four hours after lethal dose ricin aerosol exposure all survived the toxin challenge, as compared to control animals, which succumbed to ricin intoxication within 30 h. Antibody treatment at 12 h after ricin exposure resulted in the survival of only one of five monkeys, indicating that, in the majority of animals, ricin intoxication and local tissue damage had progressed beyond the point where huPB10 intervention was beneficial. Change in pro-inflammatory cytokine/chemokines levels in bronchial alveolar lavage fluids before and after toxin challenge successfully clustered monkeys based on survival, as well as treatment group. IL-6 was the most apparent marker of ricin intoxication. This study represents the first demonstration in nonhuman primates that the lethal effects of inhalational ricin exposure can be negated by a drug candidate and opens up a path forward for product development.
Applicability of Drug Response Metrics for Cancer Studies using Biomaterials

Published: September 2018

Bioengineers have built increasingly sophisticated models of the tumor microenvironment in which to study cell-cell interactions, mechanisms of cancer growth and metastasis, and to test new potential therapies. These models allow researchers to culture cells in conditions that include features of thein vivotumor microenvironment (TME) implicated in regulating cancer progression, such as ECM stiffness, integrin binding to the ECM, immune and stromal cells, growth factor and cytokine depots, and a 3D geometry more representative of the TME than tissue culture polystyrene (TCPS). These biomaterials could be particularly useful for drug screening applications to make better predictions of efficacy, offering better translation to preclinicalin vivomodels and clinical trials. However, it can be challenging to compare drug response reports across different platforms and conditions in the current literature. This is, in part, as a result of inconsistent reporting and use of drug response metrics, and vast differences in cell growth rates across a large variety of biomaterial design. This perspective paper attempts to clarify the definitions of drug response measurements used in the field, and presents examples in which these measurements can and cannot be applied. We suggest as best practice to include appropriate controls, always measure the growth rate of cells in the absence of drug, and follow our provided “decision tree” matrix when reporting drug response metrics.
Sustained hovering, head stabilization and vision through the water surface in the Pied kingfisher (Ceryle rudis)
Authors: Katzir Gadi , Berman Dotan , Nathan Moshe , Weihs Daniel
Published: September 2018

Pied kingfishers (Ceryle rudis) capture fish by plunge diving from hovering that may last several minutes. Hovering is the most energy-consuming mode of flight and depends on active wing flapping and facing headwind. The power for hovering is mass dependent increasing as the cube of the size, while aerodynamic forces increase only quadratically with size. Consequently, birds above a certain body mass can hover only with headwind and for very short durations. Hummingbirds are referred to as the only birds capable of hovering without wind (sustained hovering) due to their small size (ca. 2-20 gr), high wing-beat frequency and unique anatomy.

We studied the hovering characteristics of pied kingfishers in relation to wind and sun orientation, in 139 hovers. Furthermore, plunge diving necessitates the coping with the visual effects of light at the air/water interface. The kingfishers oriented their body axis towards the wind more than towards the sun. Hovering in little or no wind was common. With increased wind speed (a) orientation precision increased, (b) wing beat amplitude did not change, (c) wing beat frequency decreased and (d) body tilt became more horizontal. The head was highly stabilized and with orientations that indicated monocular viewing of prey.

We conclude that pied kingfishers achieve sustained hovering. This is despite their being significantly heavier than the theoretical maximum and showing ordinary kinematics and morphology. Head stabilization is a means of aiding viewing of submerged prey across the interface.
A framework for disentangling ecological mechanisms underlying the island species-area relationship

Published: September 2018

The relationship between an island’s size and the number of species on that island—the island species-area relationship (ISAR)—is one of the most well-known patterns in biogeography, and forms the basis for understanding biodiversity loss in response to habitat loss and fragmentation. Nevertheless, there is contention about exactly how to estimate the ISAR, and the influence of the three primary ecological mechanisms—random sampling, disproportionate effects, and heterogeneity— that drive it. Key to this contention is that estimates of the ISAR are often confounded by sampling and estimates of measures (i.e., island-level species richness) that are not diagnostic of potential mechanisms. Here, we advocate a sampling-explicit approach for disentangling the possible ecological mechanisms underlying the ISAR using parameters derived from individual-based rarefaction curves estimated across spatial scales. If the parameters derived from rarefaction curves at each spatial scale show no relationship with island area, we cannot reject the hypothesis that ISARs result only from random sampling. However, if the derived metrics change with island area, we can reject random sampling as the only operating mechanism, and infer that effects beyond sampling (i.e., disproportionate effects and/or heterogeneity) are also operating. Finally, if parameters indicative of within-island spatial variation in species composition (i.e., β-diversity) increase with island area, we can conclude that intra-island compositional heterogeneity plays a role in driving the ISAR. We illustrate this approach using representative case studies, including oceanic islands, natural island-like patches, and habitat fragments from formerly continuous habitat, illustrating several combinations of underlying mechanisms. This approach will offer insight into the role of sampling and other processes that underpin the ISAR, providing a more complete understanding of how, and some indication of why, patterns of biodiversity respond to gradients in island area.
Characterization of a thermal stable poliovirus mutant reveals distinct mechanisms of virion stabilization
Authors: Nguyen Y , Jesudhasan Palmy R. , Aguilera Elizabeth R. , Pfeiffer Julie K.
Published: September 2018

Enteric viruses, including poliovirus, are spread by the fecal-oral route. In order to persist and transmit to a new host, enteric virus particles must remain stable once they are in the environment. Environmental stressors such as heat and disinfectants can inactivate virus particles and prevent viral transmission. It has been previously demonstrated that bacteria or bacterial surface glycans can enhance poliovirus virion stability and limit inactivation from heat or bleach. While investigating the mechanisms underlying bacterial-enhanced virion thermal stability, we identified and characterized a poliovirus mutant with increased resistance to heat inactivation. This poliovirus mutant, M132V, harbors a single amino acid change in the VP1 capsid-coding that is sufficient to confer heat resistance. M132V was comparable to wild-type virus for replicationin vitro, as well as for replication and pathogenesis in orally-inoculated mice. Although the M132V virus was stable in the absence of bacteria or feces at most temperatures, M132V virus was stabilized by feces at very high temperatures. Additionally, the M132V virus does not have enhanced stability during bleach treatment, suggesting that thermal and bleach inactivation mechanisms are separable. Our results suggest that different mechanisms underlie virion stabilization by bacteria and the M132V mutation. Overall, this work sheds light on factors that influence virion stability.

IMPORTANCE

Viruses spread by the fecal-oral route need to maintain viability in the environment to ensure transmission. Previous work indicated that bacteria and bacterial surface polysaccharides can stabilize viral particles and enhance transmission. To explore factors that influence viral particle stability, we isolated a mutant poliovirus that is heat resistant. This mutant virus does not require feces for stability at most temperatures, but can be stabilized by feces at very high temperatures. Even though the mutant virus is heat resistant, it is susceptible to inactivation by treatment with bleach. This work provides insight into how viral particles maintain infectivity in the environment.
Involving patients and publics in medical and health care research studies: an exploratory survey on participant recruiting and representativeness from the perspective of study authors
Authors: Lander Jonas , Langhof Holger , Dierks Marie-Luise
Published: September 2018

Research on patient and public involvement so far concentrates on defining involvement, describing involvement methods, and analyzing involvement practice in various individual research disciplines. There is little empirical data on the process of and aims for selecting participants, and to what extend lay people involved in research can and should be representative of the population at large. To explore practices and perceptions on these issues and on future PPI conduct more generally, we sent an electronic survey to authors who published involvement activities as part of their studies in medical and social science journals. We identified such authors with a systematic search of five databases and applied descriptive statistics for analysis. Of those who returned the survey (n=127 of 315; 40%), most had previously conducted involvement activities (73%). 45% reported more than one type of involvement, e.g. consultation and deliberation and participation (14%) and to have recruited more than one type of participant for their PPI activity (56%), e.g. ‘lay publics’ and ‘expert publics’ (33% of 71). Representativeness was seen by most respondents as a crucial objective when recruiting participants, while less than half found the recruitment of suitable participants very easy (9%) or rather easy (34%). Many respondents found it generally difficult (52%) or very difficult (17%) to achieve good representativeness. They identified significant respective challenges and desired more guidance on various aspects of planning and conducting PPI (56%). 55% thought that the concept of “involvement” should be changed or improved. We conclude that participant recruitment and representativeness are controversial in current PPI practice given the manifold challenges mentioned by the survey respondents. Our findings may inform further research particularly regarding– the potentially large number of – unpublished PPI activities.
Scalable Nonlinear Programming Framework for Parameter Estimation in Dynamic Biological System Models
Authors: Shin Sungho , Venturelli Ophelia , Zavala Victor M.
Published: September 2018

We present a nonlinear programming (NLP) framework for the scalable solution of parameter estimation problems that arise in dynamic modeling of biological systems. Such problems are computationally challenging because they often involve highly nonlinear and stif differential equations as well as many experimental data sets and parameters. The proposed framework uses cutting-edge modeling and solution tools which are computationally efficient, robust, and easy-to-use. Specifically, our framework uses a time discretization approach that: i) avoids repetitive simulations of the dynamic model, ii) enables fully algebraic model implementations and computation of derivatives, and iii) enables the use of computationally efficient nonlinear interior point solvers that exploit sparse and structured linear algebra techniques. We demonstrate these capabilities by solving estimation problems for synthetic human gut microbiome community models. We show that an instance with 156 parameters, 144 differential equations, and 1,704 experimental data points can be solved in less than 3 minutes using our proposed framework (while an off-the-shelf simulation-based solution framework requires over 7 hours). We also create large instances to show that the proposed framework is scalable and can solve problems with up to 2,352 parameters, 2,304 differential equations, and 20,352 data points in less than 15 minutes. Competing methods reported in the computational biology literature cannot address problems of this level of complexity. The proposed framework is flexible, can be broadly applied to dynamic models of biological systems, and enables the implementation of sophisticated estimation techniques to quantify parameter uncertainty, to diagnose observability/uniqueness issues, to perform model selection, and to handle outliers.

Author summary

Constructing and validating dynamic models of biological systems spanning biomolecular networks to ecological systems is a challenging problem. Here we present a scalable computational framework to rapidly infer parameters in complex dynamic models of biological systems from large-scale experimental data. The framework was applied to infer parameters of a synthetic microbial community model from large-scale time series data. We also demonstrate that this framework can be used to analyze parameter uncertainty, to diagnose whether the experimental data are sufficient to uniquely determine the parameters, to determine the model that best describes the data, and to infer parameters in the face of data outliers.
Dynamic 3D tissue architecture directs BMP morphogen signaling duringDrosophilawing morphogenesis

Published: September 2018

At the level of organ formation, tissue morphogenesis drives developmental processes in animals, often involving the rearrangement of two-dimensional (2D) structures into more complex three-dimensional (3D) tissues. These processes can be directed by growth factor signaling pathways. However, little is known about how such morphological changes affect the spatiotemporal distribution of growth factor signaling. Here, using theDrosophilapupal wing, we address how Decapentaplegic (Dpp) / Bone Morphogenetic Protein (BMP) signaling and 3D wing morphogenesis are coupled. Dpp, expressed in the longitudinal veins (LVs) of the pupal wing, initially diffuses laterally during the inflation stage to regulate cell proliferation. Dpp localization is then refined to the LVs within each epithelial plane, but with active interplanar signaling for vein patterning, as the two epithelia appose. Our data further suggest that the 3D architecture of the wing epithelia directs the spatial distribution of BMP signaling, revealing how 3D morphogenesis is an emergent property of the interactions between extracellular signaling and tissue shape changes.

Ploidy-variable species allow direct inference of the effects of chromosome copy number on fundamental evolutionary processes. While an abundance of theoretical work suggests polyploidy should leave distinct population genomic signatures, empirical data remains sparse. We sequenced ∼300 individuals from 39 populations ofArabidopsis arenosa, a naturally diploid-autotetraploid species. We find the impacts of polyploidy on population genomic processes are subtle yet pervasive, including reduced efficiency on linked and purifying selection as well as rampant gene flow from diploids. Initial masking of deleterious mutations, faster rates of nucleotide substitution, and interploidy introgression all conspire to shape the evolutionary potential of polyploids.

Published: September 2018

The title Schiff base, C15H14N4O3, was synthesized by the condensation reaction between caprylic hydrazide and 2-acetylpyrazine. There are two independent pseudo-enantiomeric molecules, A and B, in the asymmetric unit that differ mainly in the orientation of the hydrazone units. For example, the dihedral angles between the benzene and pyrazine rings are 20.836 (13) (A) and 15.701 (14)° (B). The molecular packing features N—H...O hydrogen bonds that lead to a twisted supramolecular chain along the b-axis direction. The presence of C—H...O interactions consolidates the chains into a three-dimensional architecture. The studied sample was a two-component twin.

Authors: Etchebarne Soledad , Torres Zapata Isabel
Published: September 2018

Purpose

The purpose of this paper is to describe and explain the export behaviour (EB) developed by the Chilean service sector exporter firms using longitudinal data, to contribute to the scarce literature in this field in emerging markets.

Design/methodology/approach

Chilean service sector exporter firms are studied through a longitudinal analysis (2006 to 2015) comparing EB (continual/discontinual exporters) with respect to market diversification (MD). Considering a quantitative hypothesis test, based on a t-test, comparing these two groups of firms, using STATA software.

Findings

According to this research, scarce MD promotes a discontinual export development process in Chilean service sector exporter firms.

Practical implications

It is important to define public policies focussed on maintaining exportation over time and also to support these firms in diversifying their markets.

Originality/value

This paper shows a means of analysis, using longitudinal data, to compare large groups of firms, describing the causes of the discontinual export development process. At the same time, it enhances the literature on service sector exporters.
An investigation of the domestic and foreign tourists’ museum visit experiences
Authors: Bideci Mujde , Albayrak Tahir
Published: September 2018

Purpose

The purpose of this paper is to identify the main factors contributing to museum experience and assess the differences in museum experience perceptions of domestic and foreign tourists. Furthermore, examining the relationship between museum visit experience and overall satisfaction for the domestic and foreign tourists is another purpose of the paper.

Design/methodology/approach

Data collection was conducted using the convenience sampling method. The on-site survey was carried out with the participation of domestic and foreign tourists visiting Antalya Historical and Archaeological Museum in Turkey.

Findings

Analysis of data from 151 domestic and 151 foreign tourists visiting to Antalya Historical and Archaeological Museum indicated that edutainment, comfort, escape and aesthetic are the underlying dimensions of museum experience. The aesthetic dimension was identified as the most important aspect of the museum visit experience. In addition, museum visit perceptions of the domestic and foreign tourists and overall satisfactions with their visit were found to be different from each other.

Originality/value

The findings of this study provide a better understanding of the museum experience from the domestic and foreign tourists’ perspectives. Furthermore, the paper presents a novel and integrated approach to investigate tourist experiences in the extending museum experience literature.
Representation of cultural tourism on the Web: critical discourse analysis of tourism websites
Authors: Liasidou Sotiroula
Published: September 2018

Purpose

Culture is an important motivation force to people within the context of tourism. It provides new opportunities for destinations to promote cultural elements and attract more travellers. This study aims to investigate how the cultural heritage of Cyprus is promoted online and to identify whether the needs of travellers who focus on experiential aspects and prioritise culture can be fulfilled.

Design/methodology/approach

The research aim is fulfilled through a critical discourse analysis of selected WebPages concerning representation of the culture of Cyprus within the tourism context.

Findings

Eighteen websites were included, and the results suggest that Cyprus has Web exposure specifically promoting its cultural heritage. However, the websites have been established with different tourism scopes, with culture comprising just one part of the content. Thus, the development of specialised websites is dedicated exclusively to culture and tourism, and it seems appropriate to attract travellers interested in more educational activities with cultural and historical value. This approach would bring many benefits because this cohort of travellers is in an upper-scale tourist market.

Originality/value

This study is original in nature because it brings together the case of Cyprus, an island destination highly depended on tourism in relation to cultural tourism Web discourse. The promotion of cultural parameters will provide more opportunities for the island and escape from the 3S’s (sea, sun and sand) image to be positioned as a culturally sustainable destination.
A roadmap for applying qualitative comparative analysis in supply chain research
Authors: Russo Ivan , Confente Ilenia , Gligor David , Cobelli Nicola
Published: September 2018

Purpose

The purpose of this paper is to introduce qualitative comparative analysis (QCA) to the field of supply chain management and provide a detailed roadmap that supply chain researchers can utilize when applying this methodology.

Design/methodology/approach

Data collection focused on the evaluation of product returns management practices as perceived by business customers who operate in a supplier–customer context. In order to analyze the data using the QCA approach, a multi-step analysis was developed.

Findings

The results indicate five solutions that lead to high levels of customer satisfaction. The existence of multiple sufficient configurations for customer satisfaction indicates equifinality because multiple alternative solutions can lead to the same outcome.

Research limitations/implications

The authors make a methodological contribution by applying the QCA method to the field of supply chain management and providing a detailed roadmap that supply chain researchers can utilize.

Practical implications

The authors provide managers five different and novel combinations of antecedents that lead to higher levels of customer satisfaction.

Originality/value

This study offers supply chain researchers a better understanding of when it is appropriate to use QCA and how to apply this methodology. From a theoretical perspective, past studies focused exclusively on the “net effects” of these antecedents, thus, did not capture the complexity of the relationships between these various antecedents and customer satisfaction. This is a noteworthy contribution as it highlights the complexity of the amalgam of relationships and factors that impact customer satisfaction within the context of reverse supply chain.
Strategic human resource management practices and organizational resilience
Authors: Bouaziz Fatma , Smaoui Hachicha Zouhour
Published: September 2018

Purpose

The purpose of this paper is to investigate the relationship between strategic human resource management (SHRM) practices and organizational resilience in a Tunisian democratic transition context. It is hypothesized that five SHRM practices influence three organizational resilience dimensions.

Design/methodology/approach

The research design is based on a deductive approach. The relations were checked over two periods by using quantitative methods. Questionnaires were addressed to top managers of resilient Tunisian companies. The hypotheses were verified after.

Findings

Results showed that SHRM practices affect the resilience dimensions. Analysis showed that SHRM practices enhance the robustness of firms, especially in the second period, and significantly influence agility and integrity.

Practical implications

Managers can use these findings to develop targeted actions in HRM to enhance a specific resilience dimension. They can make better decisions based on knowledge surrounding the precise effects of SHRM practices on resilience dimensions.

Originality/value

The authors highlighted the role of SHRM in developing organizational resilience. Gaps were noticed in the organizational resilience literature. This research is among the rare studies that have investigated the linkage between SHRM practices and organizational resilience. By using quantitative methods and adopting a longitudinal perspective for analyzing data, it leads to better identify the evolution of the influence of SHRM practices on each resilience dimension over time.
How analyst recommendation change influences strategic change
Authors: Jiang Wan , Wang Linlin , Chu Zhaofang , Ma Xifang
Published: September 2018

Purpose

The purpose of this paper is to examine how analyst recommendation change is associated with a firm’s magnitude of strategic change.

Design/methodology/approach

This study argues that unfavorable analyst recommendation change serves as a powerful external assessment that current strategies are inappropriate and that changes are needed. This study also incorporates the moderating roles of CEO power and board’s informal hierarchy in the relationship between analyst recommendation change and firm’s magnitude of strategic change. Results from a sample of 824 observations generally support our predictions.

Findings

The findings of this study show that the greater the analysts downgrade for the company’s stock, the larger the magnitude of strategic change will be made. This study also considers the moderating roles of CEO power and the clarity of board’s informal hierarchy. In particular, the higher the CEO power, the weaker the relationship between analyst recommendation change and the magnitude of strategic change will be. The higher the clarity of board’s informal hierarchy, the more positive the relationship between analyst recommendation change and the magnitude of strategic change will be.

Originality/value

It extends research on the external predictors of strategic change by incorporating the role of unfavorable analyst recommendation change. In addition, it contributes to institutional theory by showing how external legitimacy pressure and internal corporate governance tool complement each other.

The purpose of this paper is to analyze the history and future of service operations, with the goal to identify key theoretical and technological advances, as well as fundamental themes that can help to imagine the future of service operations in 2050.

Design/methodology/approach

A review of the service operations literature was undertaken to inform a discussion regarding the role that technology will play in the future of service operations.

Findings

The future of service operations is framed in terms of three key themes – complexity, orchestration, and elasticity. The paper makes three contributions to the service science literature by: reviewing key themes underpinning extant service operations research to frame future trajectories of service operations research; elaborating a vision of service operations in 2050 based on history and technology; and outlining a research agenda for future service operations.

Practical implications

The case of service automation is used to provide an illustration of how the three themes converge to define future service operations, and in particular, to show how technology is recasting the role of the firm.

Originality/value

Service operations in the next 30 years will be very different from what it was in the past 30 years. This paper differs from other review papers by identifying three key themes that will characterize and instill new insights into the future of service operations research.

Published: September 2018

Purpose

The purpose of this paper is to identify the mediating effect of fan-page followers’ engagement activities and moderating role of followers’ demographic profile and trust level on their purchase intention.

Design/methodology/approach

This study utilised the customer engagement behaviour and consumer involvement theory as a foundation to explore the impact of variables. Structural equation modelling was utilised to test the model with the data collected from 307 Facebook fan pages’ followers of five Malaysian companies.

Findings

It was shown that following fan pages will influence fan page engagement, which in turn affects purchase intention and social media connectedness. Further analysis indicated that the impact of “follow” and “engagement” on purchase intention differs between genders, ages, level of trust and income.

Research limitations/implications

The study serves as a basic fundamental guideline for academics and researchers to interpret the concept of following fan pages and engagement actions and its effects on purchase intention and social media connectivity, as well as opening a vast area of unexplored researches on the subject of social media.

Practical implications

The research provides information for business-to-consumer companies in utilising fan page based on user categories.

Originality/value

This study proposes the application of an empirically tested framework to the fan-page follow actions. The authors argue that this framework can provide a useful foundation for future social commerce research. The results would help academics be aware of fan page and its user’s engagement actions, which will provide a new avenue of research.
Documenting current practices in the management of deaf suspects in the USA
Authors: Shine Beau James
Published: September 2018

Purpose

The purpose of this paper is to combine previous research on deaf suspects with the findings from data gathered from law enforcement personnel nationwide to gain an understanding of the common practices of US law enforcement when arresting, interrogating and communicating with deaf suspects.

Design/methodology/approach

In light of the limited amount of research available on handling deaf suspects, a two-part sampling approach was used. Using critical case sampling, the author surveyed law enforcement via open-ended surveys designed to solicit information about their involvement with deaf suspects and any related questions and concerns. Guided by the Wave 1 data, Wave 2 surveys were administered to law enforcement nationwide (using expert sampling).

Findings

An analysis of the two waves of data collected was used to assemble the list of current practices.

Originality/value

This study combines previous research on deaf suspects, which has been published largely through the framework of deaf studies, with the insight of practitioners to identify a list of current practices used by US law enforcement when handling deaf suspects.
Learning not to underestimate
Authors: Meslec Nicoleta , Aggarwal Ishani
Published: September 2018

Purpose

The purpose of this paper is twofold. First, it aims to isolate a new mechanism (i.e. underestimation judgments) through which gender (percentage of women in a group in particular) influences group synergy, or the extent to which groups are able to perform better than their composing members. Second, it aims to explore further the extent to which underestimation judgments are prone to change and adjustment as a result of participating in social contexts, such as groups.

Design/methodology/approach

The sample consisted of 278 student participants (161 women), nested within 66 groups. Participants performed a series of cognitive tasks with correct answers and had to rate how confident they were in the answers given.

Findings

Gender composition in terms of percentage of women is positively related to underestimation within groups and this negatively affects group synergy. The data also show that women underestimate less or improve the accuracy of their performance self-evaluation judgments after group interaction, thereby highlighting a factor (group experience) that helps women gain greater accuracy about their performance.

Research limitations/implications

Further research could explore the extent to which underestimation judgments are present in various organizational contexts and the extent to which they are prone to change.

Practical implications

Organizations and universities are invited to reflect on the relevance of self-beliefs (and underestimation in particular) on the accomplishment of cognitive tasks. Practices and policies should be geared toward the enhancement of self-knowledge accuracy, with a particular focus on the female population.

Originality/value

This paper identifies a new mechanism through which gender influences group synergy: underestimation judgments.
