AbstractSuccessful implantation is associated with a unique spatial pattern of vascular remodeling, characterized by profound peripheral neo-vascularization surrounding a peri-embryo avascular niche. We hypothesized that hyaluronan controls the formation of the unique vascular pattern encompassing the embryo. This hypothesis was evaluated by genetic modification of hyaluronan metabolism specifically targeted to embryonic trophoblast cells. The outcome of altered hyaluronan deposition on uterine vascular remodeling and post-implantation development were analyzed by MRI, detailed histological examinations, and RNA-sequencing of uterine NK cells. Our experiments revealed that eliminating the anti-angiogenic hyaluronan, led to elevated expression of MMP-9, VEGF-A and its receptor VEGFR-2, accompanied by reduced recruitment of uterine NK cells. Further local decrease in VEGFR-3 resulted in impaired formation of vascular sinuous folds, ectopic angiogenesis and dysfunctional uterine NK cells. Conversely, enhanced deposition of hyaluronan caused the expansion of the maternal-embryo barrier, leading to an increased diffusion distance and aborted implantation. These results demonstrate a pivotal role for hyaluronan in successful pregnancy by fine-tuning the peri-embryo avascular niche and maternal vascular morphogenesis.
A precision analysis method for the kinematic assembly of complex products based on equivalence of deviation source
Authors: Zhao Dongping , Wang Gangfeng , Hui Jizhuang , Hou Wei , Evans Richard David 
Published: February 2020

Purpose
The assembly quality of complex products is pivotal to their lifecycle performance. Assembly precision analysis (APA) is an effective method used to check the feasibility and quality of assembly. However, there is still a need for a systematic approach to be developed for APA of kinematic mechanisms. To achieve more accurate analysis of kinematic assembly, this paper aims to propose a precision analysis method based on equivalence of the deviation source.

Design/methodology/approach
A unified deviation vector representation model is adopted by considering dimension deviation, geometric deviation, joint clearance and assembly deformation. Then, vector loops and vector equations are constructed, according to joint type and deviation propagation path. A combined method, using deviation accumulation and sensitivity modeling, is applied to solve the kinematic APA of complex products.

Findings
When using the presented method, geometric form deviation, joint clearance and assembly deformation are considered selectively during tolerance modeling. In particular, the proposed virtual link model and its orientation angle are developed to determine joint deviation. Finally, vector loops and vector equations are modeled to express deviation accumulation.

Originality/value
The proposed method provides a new means for the APA of complex products, considering joint clearance and assembly deformation while improving the accuracy of APA, as much as possible.
Measuring the unknown

Published: February 2020

PurposeIn the current digital era where online content is riddled with fabricated metrics and rankings, this research aims to investigate the underpinning mechanisms of the calculative practices which actors engage with to evaluate digital platform content in the absence of well-defined performance measures.Design/methodology/approachThe paper focuses on the online, photo-sharing platform Instagram which is devoid of common performance measures such as rankings, ratings and reviews. The authors applied netnographic methods to capture users' actions and interactions at the Greek Instagram community. The authors adopt a practice lens as informed by Schatzki's ‘site ontology’ to capture actors' calculative practices as organised by rules, teleoaffective structures and general and practical understandings.FindingsPlatform actors engage in aesthetic and palpable evaluations of other user profiles and their posted content. They employ permissible (e.g., using third-party apps) and illicit (e.g., lobbying and procuring engagement) tactics to measure and manage digital platform performance, fabricate metrics and blur others' evaluations, in pursuit of prestige and material teleologies. Their calculative practices are conditioned by an implicit social etiquette, which permeates the platform both horizontally and vertically.Originality/valueFirst, the paper captures and theorises the mechanisms which underpin actors' calculative practices for performance measurement in the absence of robust judgement devices. Second, it demonstrates how ambiguous assemblages of material and prestige teleologies, aesthetic and palpable evaluative regimes and implicit rules and practical expertise collectively invoke platform actors' calculative practices and the construction of performance measures. In doing so, it contributes to performance measurement literature via demonstrating how management accounting is implicated in the evaluation of digital platform outputs.Practical implicationsThe paper provides insight on how platform actors fabricate performance metrics, what they perceive as ‘good’ online content and what constitutes an ‘impactful’ user account or a ‘successful’ social media campaign. Such findings are valuable to management accountants, entrepreneurs and practitioners who seek to evaluate digital platform performance.
Relationships among employee acting, customer-perceived service quality, emotional well-being and value co-creation
Authors: Huang Chih-Hsuan , Lin Yuan-Chen 
Published: February 2020

PurposeHinged on the transformative service paradigm, this study investigates the relationships among employee acting, customer-perceived service quality, customer emotional well-being, and their value co-creation. Feelings of gratitude among customers may moderate the effect of perceived service quality on their emotional well-being (i.e., positive and negative affects).Design/methodology/approachA pair study using a structural equation model was conducted to gather data from a financial service organization in a rural area.FindingsThe results show how customers perceive service quality positively impacts their emotional well-being immediately after receiving a financial service, which in turn affects their value co-creation. Hence, feelings of gratitude moderate the effect of perceived service quality on customer positive affect.Originality/valueThis study responds to calls for more studies on how service interactions influence customer well-being in the financial services context. This study is among the few that examine moderation effects of customer feelings of gratitude on their emotional well-being to explain why a positive emotion might sway their short-term well-being.
Using a look-up table technique and finite element calculations for quick detection of stiff inclusions in silicone rubber
Authors: Jonsson Ulf G. , Lindahl Olof A. , Andersson Britt M. 
Published: February 2020

PurposeThe aim of the study was to show that a new method, using a look-up table technique, can be used to detect the presence and position of an inclusion embedded in a tissue-like material. Due to the time-consuming nature of the finite element (FE) method or FEM, real-time applications involving FEM as part of a control loop, are traditionally limited to slowly varying systems. By using a simplified two-dimensional FE model and a look-up table, we show by simulations and experiments that it is possible to achieve reasonable computational times in a tactile resonance sensor application.Design/methodology/approachA piezoelectric disk was placed in the center of a silicone rubber disk (SRD) with viscoelastic properties, where it acted as both sensor and actuator and dissipated radial acoustic waves into the silicone. The look-up table was constructed by calculating the radial Lamb wave transition frequencies in the impedance frequency response of the sensor while varying the position of an inclusion. A position-matching algorithm was developed that matched measured and calculated Lamb wave transitions and thereby identified the presence and position of an inclusion.FindingsIn an experiment, the position of a hard inclusion was determined by measuring the Lamb transition frequencies of the first radial resonance in two SRDs. The result of the matching algorithm for Disk 1 was that the matched position was less than 3% from the expected value. For Disk 2, the matching algorithm erroneously reported two false positions before reporting a position that was less than 5% from the expected value. An explanation for this discrepancy is presented. In a verifying experiment, the algorithm identified the condition with no inclusion present.Originality/valueThe approach outlined in this work, adds to the prospect of developing time-sensitive diagnostic instruments. This approach has the potential to provide a powerful technique to quickly present spatial information on detected tumors.
Formation of customer-based brand equity via authenticity
Authors: Rodríguez-López María Eugenia , del Barrio-García Salvador , Alcántara-Pilar Juan Miguel 
Published: February 2020

Purpose
This study aims to examine the extent to which customers’ perceptions of restaurant authenticity facilitate the establishment’s customer-based brand equity (CBBE) – both directly and indirectly – via customer satisfaction. The study also analyzes whether restaurant type moderates the antecedent relationships of CBBE formation.

Design/methodology/approach
Two restaurants of different types were selected for the study: a mid-scale and a moderate/casual restaurant. Based on a final total sample of 402 customers of both restaurant types, a moderated mediation regression model was used.

Findings
It was found that the level of authenticity perceived by the restaurant visitor during the gastronomic experience is an antecedent of restaurant brand equity formation, both directly and indirectly, via customer satisfaction. Furthermore, these antecedent relationships were found to be partially moderated by restaurant type.

Research limitations/implications
Only two restaurants were used for the study. This study could be replicated by comparing other types of restaurants with differentiated characteristics to test whether the results obtained for these two types can be extrapolated to the rest.

Originality/value
There is no empirical evidence in the literature regarding the possible moderating effect of restaurant type on brand equity formation, so the particular note is the simultaneous application of CBBE measurement to the analysis of two different types of restaurant and the differences in their brand equity formation. On the other hand, there are few studies that use moderated mediation regression analysis as a methodological technique in the field of restaurants, so this is an interesting methodological contribution.
Testing moderating effects on the relationships among on-board cruise environment, satisfaction, perceived value and behavioral intentions
Authors: Calza Francesco , Pagliuca Margherita , Risitano Marcello , Sorrentino Annarita 
Published: February 2020

Purpose
This study aims to investigate both the relationships among the on-board environment, overall satisfaction, perceived value and behavioral intentions and the moderating effects of gender, employment status, group composition and the propensity to stay on board in the context of cruise experience.

Design/methodology/approach
Relationships among constructs were tested on the basis of 417 surveys collected and analyzed with the structural equation modeling approach of partial least squares path modeling. A multi-group analysis was used to test the moderating effects.

Findings
The research findings suggest that on-board environment is a good predictor of behavioral intentions, but that the relationship is strongly mediated by satisfaction and perceived value. Moreover, the multi-group analysis of moderating effects indicated various differences that offer interesting insights for segmenting passengers; these insights have substantial implications for future studies and cruise line companies alike.

Practical implications
This study offers useful insights for managers who want to differentiate their value proposition with ship-centered elements.

Originality/value
This study contributes to the literature by providing a theoretical framework and empirical evidence for analyzing the role of the perceived on-board environment in passenger experience. From a managerial perspective, the moderating effects offer new insights for targeting and customizing the cruise experience value proposition.

Authors: Andreu Luisa , Bigne Enrique , Amaro Suzanne , Palomo Jesús 
Published: February 2020

Purpose
The purpose of this study is to examine Airbnb research using bibliometric methods. Using research performance analysis, this study highlights and provides an updated overview of Airbnb research by revealing patterns in journals, papers and most influential authors and countries. Furthermore, it graphically illustrates how research themes have evolved by mapping a co-word analysis and points out potential trends for future research.

Design/methodology/approach
The methodological design for this study involves three phases: the document source selection, the definition of the variables to be analyzed and the bibliometric analysis. A statistical multivariate analysis of all the documents’ characteristics was performed with R software. Furthermore, natural language processing techniques were used to analyze all the abstracts and keywords specified in the 129 selected documents.

Findings
Results show the genesis and evolution of publications on Airbnb research, scatter of journals and journals’ characteristics, author and productivity characteristics, geographical distribution of the research and content analysis using keywords.

Research limitations/implications
Despite Airbnb having a history of 10 years, research publications only started in 2015. Therefore, the bibliometric study includes papers from 2015 to 2019. One of the main limitations is that papers were selected in October of 2019, before the year was over. However, the latest academic publications (in press and earlycite) were included in the analysis.

Originality/value
This study analyzed bibliometric set of laws (Price’s, Lotka’s and Bradford’s) to better understand the patterns of the most relevant scientific production regarding Airbnb in tourism and hospitality journals. Using natural language processing techniques, this study analyzes all the abstracts and keywords specified in the selected documents. Results show the evolution of research topics in four periods: 2015-2016, 2017, 2018 and 2019.
Understanding the forces and critical features of a new reporting and budgeting system adoption by Indonesian local government
Authors: Harun Harun , Carter David , Mollik Abu Taher , An Yi 
Published: February 2020

Purpose
This paper aims to critically explore the forces and critical features relating to the adoption of a new reporting and budgeting system (RBS) in Indonesian local governments.

Design/methodology/approach
The study is based on an intensive analysis of document sources and interview scripts around the institutionalization of RBS by the Indonesian government and uses the adaption of Dillard et al. (2004) institutional model in informing its findings.

Findings
The authors find that at the national level, the key drivers in RBS adoption were a combination of exogenous economic and coercive pressures and the wish to mimic accounting reforms in developed nations. At the local government level, the internalization of RBS is a response to a legal obligation imposed by the central government. Despite the RBS adoption has strengthened the transparency of local authorities reports – it limits the roles of other members of citizens in determining how local government budgets are allocated.

Research limitations/implications
The results of the study should be understood in the historical and institutional contexts of organizations observed.

Practical implications
The authors reinforce the notion that accounting as a business language dominates narratives and conversations surrounding the nature of government reporting and budgeting systems and how resource allocation is formulated and practiced. This should remind policymakers in other developing nations that any implementation of a new accounting technology should consider institutional capacities of public sector organizations and how the new technology benefits the public.

Social implications
The authors argue that the dominant role of international financial authorities in the policymaking and implementation of RBS challenges the aim of autonomy policies, which grant greater roles for local authorities and citizens in determining the nature of the budgets and operation of local authorities.

Originality/value
This study extends institutional theory by adapting the Dillard et al. (2004) model in explaining the forces, actors and critical features of a new accounting system adoption by local governments.

Published: February 2020

PurposeThis study aims to explore the emotional experiences of children in selected orphanages.Design/methodology/approachThe study was executed in three orphanages in Accra, Tema and Aburi through the use of semi-structured interviews and observations.FindingsIn total, 15 respondents reported some emotional experiences such as loneliness, entrapment, deprivation, rejection and helplessness.Originality/valueThe number of children living in orphanages has increased in recent times. Previous studies have examined psychological risk and protective factors among children orphaned as a result of HIV/AIDS and also compared orphan children to non-orphans. Notwithstanding this, little is known about the emotional experiences of children living in orphanages in Ghana.
Implementation of a schema therapy awareness group for adult male low secure patients with comorbid personality difficulties: reflections and challenges
Authors: Lowenstein Joseph Aaron , Stickney Jennifer , Shaw Ida 
Published: February 2020

PurposeThe purpose of this study/paper is to describe the implementation of a six-month schema therapy awareness (STA) group. Research supporting individual schema therapy (ST) as an effective intervention for personality disorder is growing steadily within a number of settings including with forensic patients. Alongside individual ST, positive results have been reported for group ST. However, to the best of the authors’ knowledge, no current published research exists with regard to the use of group ST within forensic populations and more specifically within a low secure environment.Design/methodology/approachThis paper describes the implementation of a six-month schema therapy awareness (STA) group with individuals situated within a low secure environment.FindingsFor individuals transitioning into the community from a secure setting, the focus of risk management should attempt to move away from external controls towards more of a reliance on internal factors. In ST, this is achieved by understanding the role of schema modes (and underlying schemas) that are linked to an individual’s offences/risk and developing this understanding into a coherent and accessible formulation for the individual to make changes.Research limitations/implicationsFurther robust research evaluating clinical change is recommended as the next step.Practical implicationsThe group protocol is described along with the challenges and potential solutions experienced during the implementation. This provides an opportunity for other professionals to replicate this approach in the future.Originality/valueWith regard to group ST within forensic populations, the research is sparse at present and this study focusses on practical application of theory and the challenges of operationalising a STA group.
Breaking the health-care workplace conflict perpetuation cycle
Authors: Patton Cheryl M. 
Published: February 2020

PurposeThe purpose of this study is to describe and interpret the interpersonal and intragroup conflict experiences of staff-level employees and leaders in the medical imaging technology field, working in US tertiary care centers to extract mitigation and management strategies.Design/methodology/approachA total of 13 medical imaging technologists, who were employed in leadership and staff positions throughout the USA, offered their in-depth accounts of workplace conflict in this interpretive phenomenological investigation.FindingsConflict avoidance was a predominant conflict management style. This style did little to effectively manage workplace conflict. In some cases, it led to deleterious effects on individuals and organizations and created conflict perpetuation. With proper conflict mitigation and management, the conflict perpetuation cycle can be broken.Research limitations/implicationsGeneralization beyond the group being studied is not applicable, as it is not the intent of phenomenological research. Four leaders participated in the research study. To examine this population more completely, a greater sample size is required. This recommendation also applies to the staff technologist roles. Another limitation involved the leader/staff-level representation inequality, as well as the male–female representation. These imbalances made it difficult to effectively make comparisons of the experiences of leaders with staff-level technologists, and males with females.Practical implicationsOffering the medical imaging workforce emotional intelligence training, health-care administrators can invest in their leaders and staff technologists. Medical imaging schools can incorporate emotional intelligence training into their curricula. Clear policies may decrease the ill effects of change when unforeseeable occurrences result in schedule modifications. Making technologists fully aware of who is responsible for shift coverage when these events occur may reduce negative impact. Trainings in organizational change, collaboration or positivity may be warranted, depending on findings of cultural assessments. Team-building events and opportunities for employees to intermingle may also be used to improve a departmental or organizational culture.Social implicationsMitigating and managing health-care workplace conflict more effectively may prevent patient harm, thus improving the health of members of society.Originality/valueAccording to recent studies, conflict, and the incivility that often accompanies it, has been on the increase in US organizations overall, and in health care specifically. Conflict that perpetuates can adversely affect health-care organizations and its employees. This paper offers mitigation and management strategies to prevent such consequences.
