Published: July 2021

Introduction
Limitations in insurance coverage may cause patients to turn to crowdfunding to raise money for gender-affirming procedures. In this study, we analyze the impact of Medicaid insurance coverage on gender-affirming mastectomy campaigns posted on GoFundMe.com.

Methods
Between March 1 and 12, 2021, we accessed GoFundMe.com to analyze available campaigns requesting monetary contributions for gender-affirming mastectomy. Campaigns were identified using the search term “top surgery” followed by the state's name. Duplicate campaigns, campaigns whose primary goal was not gender-affirming mastectomy, and ongoing campaigns were excluded. Campaigns were then categorized according to their state's coverage of gender-affirming surgery: explicit exclusion (EE), explicit inclusion (EI), or no explicit statement of gender-affirming care. We collected data on the number of donors and shares, the fundraising goal, and the total amount raised for each campaign. Common themes within campaign narratives were identified and assessed by each reviewer. Finally, we collected data on the photographs posted by campaign creators.

Results
Our search yielded 790 campaigns, with an overall mean of 58 ± 99 donors and 212 ± 288 shares. The mean fundraising goal and amount raised among all campaigns were $6811 ± $5027 and $2579 ± $3072, respectively. Fundraising goals were most likely to be met in an EI state than an EE state (26.3% vs 8.1%; P < 0.001). The mean amount sought was highest in EE states and lowest in EI states, whereas the mean amount raised was lowest in EE states and highest in EI states. Of the campaigns, 97.1% mentioned personal or situational characteristics in the narrative section; 16.2% of all campaigns expressed negative feelings about posting on GoFundMe.com to raise money for their surgeries.

Conclusion
Disparities in health care coverage of gender-affirming surgeries were seen between state categories, with a decreased need for crowdfunding in states explicitly including coverage of gender-affirming surgery. Many transgender patients used crowdfunding to pay for transition-related health care costs, relying on the kindness of strangers and their social network at the expense of their personal privacy. Expansion of legislative coverage of gender-affirming surgeries may alleviate some of this financial burden and reduce transgender patients' reliance on crowdfunding campaigns.
Spontaneous Osteogenesis of Dehiscent Frontal Sinus Wall After Endoscopic Removal of Mucocele

Published: July 2021

Abstract
Paranasal sinus mucoceles commonly cause erosions of the bony walls. Currently, such defects can be managed conservatively with promising short-term outcomes. Long-term outcomes of these defects have not been described. The authors describe a 28-year-old patient with complete spontaneous osteogenesis of the large dehiscent frontal sinus posterior wall, secondary to a large mucocele, 9 years from functional endoscopic sinus surgery with the defect managed conservatively. Owing to the osteogenic potential of the dura, the authors postulate that the presence of dura beneath the bony deformity of the posterior frontal sinus wall had likely initiated the osteogenesis and restored the defect. This report substantiates studies demonstrating the osteogenic potential of an intact dura. Conservative management is an option for selected large defects of the posterior wall of the frontal sinus.

Objective:
To analyze serial biomarkers of the persistent inflammation, immunosuppression, and catabolism syndrome (PICS) to gain insight into the pathobiology of chronic critical illness (CCI) after surgical sepsis.

Background:
Although early deaths after surgical intensive care unit sepsis have decreased and most survivors rapidly recover (RAP), one third develop the adverse clinical trajectory of CCI. However, the underlying pathobiology of its dismal long-term outcomes remains unclear.

Methods:
PICS biomarkers over 14 days from 124 CCI and 225 RAP sepsis survivors were analyzed to determine associations and prediction models for (1) CCI (≥14 intensive care unit days with organ dysfunction) and (2) dismal 1-year outcomes (Zubrod 4/5 performance scores). Clinical prediction models were created using PIRO variables (predisposition, insult, response, and organ dysfunction). Biomarkers were then added to determine if they strengthened predictions.

Results:
CCI (vs RAP) and Zubrod 4/5 (vs Zubrod 0–3) cohorts had greater elevations in biomarkers of inflammation (interleukin [IL]-6, IL-8, interferon gamma-induced protein [IP-10], monocyte chemoattractant protein 1), immunosuppression (IL-10, soluble programmed death ligand-1), stress metabolism (C-reactive protein, glucagon-like peptide 1), and angiogenesis (angiopoietin-2, vascular endothelial growth factor, vascular endothelial growth factor receptor-1, stromal cell-derived factor) at most time-points. Clinical models predicted CCI on day 4 (area under the receiver operating characteristics curve [AUC] = 0.89) and 1 year Zubrod 4/5 on day 7 (AUC = 0.80). IL-10 and IP-10 on day 4 minimally improved prediction of CCI (AUC = 0.90). However, IL-10, IL-6, IL-8, monocyte chemoattractant protein 1, IP-10, angiopoietin-2, glucagon-like peptide 1, soluble programmed death ligand-1, and stromal cell-derived factor on day 7 considerably improved the prediction of Zubrod 4/5 status (AUC = 0.88).

Conclusions:
Persistent elevations of PICS biomarkers in the CCI and Zubrod 4/5 cohorts and their improved prediction of Zubrod 4/5 validate that PICS plays a role in CCI pathobiology.
Space groups and crystallographic symmetry: writing a multi-featured tutorial in a new style
Authors: Foxman Bruce M. 
Published: July 2021

Knowledge of space groups and the implications of space group symmetry on the physical and chemical properties of solids are pivotal factors in all areas of crystalline solids. As Jerry Jasinski and I met to bring our ideas in teaching this subject to life, we both felt that `early and often' – teaching the concepts with textual and visual reinforcement, is the key to providing a sound basis for students in this subject. The tutorial contains > 200 PowerPoint `slides', in five modules, arranged by crystal class; a sixth module covers special topics. A `credits' module gives the direct addresses of all embedded links. Space-group diagrams appear in International Tables format. The triclinic and monoclinic groups (2 + 13) are built from `scratch', and are derived from the Hermann–Mauguin symbol. An additional section provides practice on many (but not all) of the orthorhombic groups in crystal class 222. Finally, a `Special Topics' section on enantiomorphous space groups features space groups P41 and P43. In the tutorial, lattice points build iteratively and interactively via keyclick, and the coordinates of points `pop up' as the unit cell is filled. We trust that the elements of guidance, inquiry and occasional humor will make the learning process enjoyable.
Linking brand attitude to word-of-mouth and revisit intentions in the restaurant sector

Published: July 2021

PurposeFollowing the planned behaviour theory, the aim of the paper is to analyse the role played by brand attachment, brand characteristics and congruence in enhancing brand attitude while leading to revisit intentions and word-of-mouth (WOM) in the restaurant sector.Design/methodology/approachThe study is based on the quantitative method and considered 464 questionnaires fulfilled by customers of restaurants. The data were explored employing the partial least square–structural equation modelling (PLS-SEM).FindingsThis study expands the literature about WOM and revisit intentions. The paper states that brand attitude positively influenced revisit intentions and WOM. Besides, findings highlighted that analysed concepts were positively correlated and that they played an important role in impacting revisit intentions and WOM, apart from one factor: social self-congruity, which was not significantly related to brand attitude.Practical implicationsThe results of this paper show practitioners how to develop suitable strategies that set the bases for developing customer loyalty and repeat business. By putting into practice these suggestions in the restaurant sector, brands can easily build up their attitude and boost a positive WOM and the intention to revisit.Originality/valueThe study offers a conceptual framework to explore the significance of several factors, including revisit intentions and WOM. In practice, taking into account the proposed framework, it is suggested that restaurant managers should assess these two items using several factors including congruence, brand characteristics and brand attachment.
Analysis of the two-way causal nexus between macroeconomic factors and infrastructure development: the experience of selected African countries
Authors: Azolibe Chukwuebuka Bernard 
Published: July 2021

PurposeThe purpose of this study is to analyze the two-way causal nexus between macroeconomic factors such as foreign aid, industrialization, economic growth, population growth, urbanization, control of corruption and the infrastructure development index of the top-ranking African countries from 2003 to 2018.Design/methodology/approachThe study adopts various econometric tools such as cross-sectional dependence test, panel unit root and cointegration test and Dumitrescu and Hurlin panel Granger causality test in ascertaining the relevant relationships between the variables under consideration.FindingsThe main findings of the Granger causality test result revealed a bidirectional causal relationship between foreign aid and infrastructure and between urbanization and infrastructure. The study also found unidirectional causality running from population growth to infrastructure while a zero causal relationship existed between industrialization and infrastructure, economic growth and infrastructure and lastly, between control of corruption and infrastructure. The study concludes that the major macroeconomic factors that influence infrastructure development in these selected African countries are foreign aid, population explosion and urbanization. Also, their high infrastructure development index has causal influence in only attracting more foreign aid and also promoting urban expansion.Originality/valueTo the best of the author's knowledge, the study is unique as it is the first to determine the two-way causal nexus between macroeconomic factors and infrastructure development using a sample of the top ten African countries in infrastructure ranking. The findings reflect the current situation in Africa.
When the sense of place value is challenged by pandemic: value exchange in indigenous community-based tourism in Sade-Lombok, Indonesia
Authors: Rembulan Cicilia Larasati , Kusumowidagdo Astrid 
Published: July 2021

Purpose
The purpose of this study is to investigate problems that emerged in indigenous community-based tourism during the COVID-19 pandemic, to identify the actors involved and to identify values that were exchanged between actors during the pandemic. This research is crucial given the limited studies around indigenous community-based tourism during the pandemic, especially within the perspectives of value exchange theory.

Design/methodology/approach
This research used a constructionist paradigm with a qualitative case study design. Data collection included interviews with six participants, virtual observation, an open-ended questionnaire to 22 community members and 20 tourists, analysis of a book written by Sade’s customary chief and social media artifacts. This study was conducted during the COVID-19 pandemic, where physical distancing measures were applied, therefore most data were collected remotely. Purposive sampling was used and research credibility was increased through detailed note taking, data sources triangulation and member checking. Data analysis was conducted with a coding process, which involved continuous iterations.

Findings
Problems identified were decreased revenue and power disadvantage suffered by indigenous community-based tourism. The actors involved in value exchanges varied, including value supporter (i.e. government, private sector such as television, university), value creator (i.e. tourist) or secondary value provider (i.e. travel agent). Values emerged in the interaction between actors in the network. Changes in value exchanges were in terms of value types, relationship intensity between actors and ways of doing the exchange. Non-human factor (i.e. non-actor) was also involved.

Research limitations/implications
Due to restrictive circumstances (i.e. COVID-19 pandemic), the data collection procedure was limited to online communications and letter correspondence. Therefore, opportunities to capture the full phenomenon might be missed as the researchers could not physically meet with the participant.

Practical implications
It was possible for value exchange to alter due to situational factors, including a pandemic. Business diversification is needed by indigenous community-based tourism to achieve a power advantage. Values were found in the relationship between actors, hence, meeting channels or dialogue with other actors could be optimized.

Originality/value
The context of this study, which was indigenous community-based tourism during a pandemic contributed to the study’s originality. Research in this context, which used a clear theoretical framework such as value exchange theory, is scarce. Thus, opportunities for transferability are broad.
Socialising tourism after COVID-19: reclaiming tourism as a social force?
Authors: Higgins-Desbiolles Freya , Bigby Bobbie Chew , Doering Adam 
Published: July 2021

PurposeThis article considers the possibilities of and barriers to socialising tourism after the coronavirus disease 2019 (COVID-19) pandemic. Such an approach allows us to transform tourism and thereby evolve it to be of wider benefit and less damaging to societies and ecologies than has been the case under the corporatised model of tourism.Design/methodology/approachThis conceptual analysis draws on the theorisation of “tourism as a social force” and the new concept of “socialising tourism”. Using critical tourism approaches, it seeks to identify the dynamics that are evident in order to assess the possibilities for socialising tourism for social and ecological justice. It employs an Indigenous perspective that the past, present and future are interconnected in its consideration of tourism futures.FindingsCOVID-19 has fundamentally disrupted tourism, travel and affiliated industries. In dealing with the crisis, borders have been shut, lockdowns imposed and international tourism curtailed. The pandemic foregrounded the renewal of social bonds and social capacities as governments acted to prevent economic and social devastation. This disruption of normality has inspired some to envision radical transformations in tourism to address the injustices and unsustainability of tourism. Others remain sceptical of the likelihood of transformation. Indeed, phenomena such as vaccine privilege and vaccine tourism are indicators that transformations must be enabled. The authors look to New Zealand examples as hopeful indications of the ways in which tourism might be transformed for social and ecological justice.Practical implicationsThis conceptualisation could guide the industry to better stakeholder relations and sustainability.Social implicationsSocialising tourism offers a fruitful pathway to rethinking tourism through a reorientation of the social relations it fosters and thereby transforming its social impacts for the better.Originality/valueThis work engages with the novel concept of “socialising tourism”. In connecting this new theory to the older theory of “tourism as a social force”, this paper considers how COVID-19 has offered a possible transformative moment to enable more just and sustainable tourism futures.
Data usage-based privacy and security issues in mobile app recommendation (MAR): a systematic literature review
Authors: Beg Saira , Khan Saif Ur Rehman , Anjum Adeel 
Published: July 2021

PurposeSimilarly, Zhu et al. (2014) and Zhang et al. (2014) stated that addressing privacy concerns with the recommendation process is necessary for the healthy development of app recommendation. Recently, Xiao et al. (2020) mentioned that a lack of effective privacy policy hinders the development of personalized recommendation services. According to the reported work, privacy protection technology methods are too limited for mobile focusing on data encryption, anonymity, disturbance, elimination of redundant data to protect the recommendation process from privacy breaches. So, this situation motivated us to conduct a systematic literature review (SLR) to provide the viewpoint of privacy and security concerns as mentioned in current state-of-the-art in the mobile app recommendation domain.Design/methodology/approachIn this work, the authors have followed Kitchenham guidelines (Kitchenham and Charters, 2007) to devise the SLR process. According to the guidelines, the SLR process has three main phases: (1) define, (2) conduct the search and (3) report the results. Furthermore, the authors used systematic mapping approach as well to ensure the whole process.FindingsBased on the selected studies, the authors proposed three main thematic taxonomies, including architectural style, security and privacy strategies, and user-usage in the mobile app recommendation domain. From the studies' synthesis viewpoint, it is observed that the majority of the research efforts have focused on the movie recommendation field, while the mainly used privacy scheme is homomorphic encryption. Finally, the authors suggested a set of future research dimensions useful for the potential researchers interested to perform the research in the mobile app recommendation domain.Originality/valueThis is an SLR article, based on existing published research, where the authors identified key issues and future directions.
Measuring the geometry of nature and architecture: comparing the visual properties of Frank Lloyd Wright's Fallingwater and its natural setting
Authors: Vaughan Josephine , Ostwald Michael J. 
Published: July 2021

PurposeFrank Lloyd Wright's famous house Fallingwater has been the subject of enduring scholarly debate centred on the allegedly clear parallels between its form and that of its surrounding natural setting. Despite these claims being repeated many times, no quantitative approach has ever been used to test this argument. In response, this paper uses a quantitative method, fractal analysis, to measure the relationship between the architecture of Fallingwater and of its natural surroundings.Design/methodology/approachUsing fractal dimension analysis, a computational method that mathematically measures the characteristic visual complexity of an object, this paper mathematically measures and tests the similarity between the visual properties of Fallingwater and its natural setting. Twenty analogues of the natural surroundings of Fallingwater are measured and the results compared to those developed for the properties of eight views of the house.FindingsAlthough individual results suggest various levels of visual similarity or difference, the complete set of results do not support the claim that the form of Frank Lloyd Wright's Fallingwater exhibits clear visual similarities to the surrounding landscape.Originality/valueIn addition to testing a prominent theory about Wright's building for the first time, the paper demonstrates a rare application of fractal analysis to interpreting relations between architecture and nature.

Published: July 2021

AbstractPsoriasis has been associated with the risk of several ocular complications; however, its relationship with retinal diseases remains unknown. This study aimed to investigate the risk of developing retinal diseases in patients with psoriasis. Study participants were recruited from the National Health Insurance Research Database in Taiwan. A total of 11 729 psoriasis patients and 117 290 matched controls were included, showing an incidence rate of 121.15 and 28.34 cases of retinal diseases per 100 000 person‐years, respectively. Compared with controls, patients with psoriasis had an adjusted hazard ratio (aHR) of 3.40 (95% confidence interval [CI], 2.63–4.39) for retinal diseases after adjustment for potential confounders. Regarding the individual retinal disease, psoriasis patients had a significantly higher risk of developing retinal detachment (aHR, 5.07; 95% CI, 2.92–8.79), retinal vascular occlusion (aHR, 3.75; 95% CI 2.42–5.82), and retinopathy (aHR, 2.84; 95% CI, 1.99–4.05) than controls. In conclusion, patients with psoriasis had a significantly higher risk of retinal diseases than controls. Further studies are necessary to investigate the pathophysiology underlying the relationship between psoriasis and retinal diseases.
Acquisition geometry analysis with point‐spread functions
Authors: Revelo‐Obando Billy , Blacquière Gerrit 
Published: July 2021

ABSTRACTSeismic data are traditionally acquired based on spatial sampling requirements, noise properties and budgetary constraints. However, designing a survey without taking into account the complexity of the subsurface may result in an image without the expected quality. Also, the subsequent preprocessing and processing steps may exploit or misuse the acquired data. The design should therefore incorporate the complexity of the subsurface and the (pre)processing steps that will be followed. We propose an analysis method that evaluates if the proposed combination of survey design, preprocessing and processing for a specific subsurface model fulfils a pre‐defined quality criterion. With our method, we estimate a set of point‐spread functions that correspond to the chosen combination, and we analyse their resolution and illumination‐detection properties in the spatial and wavenumber domains, respectively. The estimated point‐spread functions include the scattering and propagation effects generated by the subsurface, including internal multiples. We show that in some cases, the use of internal multiples in imaging can improve amplitude and resolution compared with the use of primaries only. The proposed analysis method is also used to evaluate the effect of blending noise when blended acquisition is carried out.
