Utilization of Rhinoplasty Worksheets among Practicing Facial Plastic Surgeons
Authors: Davila Richard O. , Audlin Jason , Suryadevara Amar 
Published: August 2021

Background:
Rhinoplasty is the most commonly performed procedure by facial plastic surgeons, yet many consider it the most complex and variable surgery performed. Yet no standardized surgical worksheet has been established to document the maneuvers and anatomical changes made despite the known high rate of revision surgery. This study aimed to assess the utility and utilization of rhinoplasty surgical worksheets amongst facial plastic surgeons, as well as the perceptions and attitudes toward standardization of a common rhinoplasty surgical worksheet.

Method:
We distributed an online survey to all active members of the American Academy of Facial Plastic and Reconstructive Surgery, in order to assess trends in utilization of surgical worksheets and the willingness of physicians to adhere to a standardized worksheet to be included in patient’s medical records.

Results:
When surveyed, 84 of the 130 respondents reported using a surgical worksheet, with 63 of 84 mentioned using a variation of their own custom worksheets. Of the 84 surgeons, 45 used these worksheets “often” or “always” during follow-up appointments. However, 111 of the 130 reported “never” or “rarely” receiving a surgical worksheet from another provider for revision rhinoplasties. In total, 96 of the 130 respondents were “strongly in favor” or “in favor” of sharing worksheets with other providers and 87/130 were in favor of establishing a standardized rhinoplasty worksheet for all rhinoplasty patients.

Conclusions:
A majority of respondents reported using surgical worksheets for rhinoplasties with very few reporting ever receiving other surgeons’ worksheets prior to revision rhinoplasties. Roughly three fourths of respondents were in favor of sharing worksheets along with a majority in favor of a standardized worksheet. This would represent a significant change in practice along with potentially increased collaboration between surgeons and subsequent advancement of patient care.

Summary:
Radiation therapy following oncologic resection can result in incisional breakdown, delay or cessation of wound healing, and exposure of structures. Impaired wound healing often mandates free tissue transfer for definitive closure and preservation of function. We present the case of a 16-year-old male patient who had a major incisional dehiscence following resection of a synovial sarcoma of the lower leg after postoperative irradiation. The progressive wound breakdown failed to respond to local wound care or negative pressure therapy and progressed to expose tendons of the distal leg. The patient was successfully treated with SkinTE, an autologous homologous skin graft and casting. Healing was slow but the wound filled with granulation tissue (which covered the tendon), epithelialized, and led to an excellent cosmetic and functional result. This highlights the potential of stem cell therapy and other forms of regenerative methods in healing of complicated wounds.

Authors: Bawazir Maram , Lozano Teresa , Cohen Donald M. , Islam Mohammed N. , Bhattacharyya Indraneel 
Published: August 2021

Abstract
Steatocystoma is a benign adnexal tumor that originates from sebaceous glands or ducts. Steatocystoma simplex presents as a solitary, noninherited tumor that affects adults with equal sex predilection. It can affect any part of the body and is seen most commonly on the skin of the face and neck. Involvement of the oral mucosa is extremely rare. To the best of our knowledge, only 3 intraoral cases have ever been reported. We report a rare case of steatocystoma simplex presented in a 17-year-old male patient involving the buccal mucosa.
Lymphoepithelial Carcinoma of the Parotid: A Case Report and Review of the Literature
Authors: Felicelli Christopher , Alexiev Borislav , Samant Sandeep , Johnson Daniel 
Published: August 2021

Abstract
Lymphoepithelial carcinoma (LEC) is an incredibly rare entity, accounting for less than 0.5% of all salivary gland malignancies. We present a case of a Southeast Asian women who presented with a rapidly enlarging parotid mass causing compressive symptoms. Surgical resection revealed nests of EBV-in situ hybridization positive pleomorphic cells surroundded by a dense lymphoplasmacytic infiltrate, consistent with LEC. The differential diagnosis and literature surrounding this rare entity is discussed.
Species relationships in the extremes and their influence on community stability
Authors: Ghosh Shyamolina , Cottingham Kathryn L. , Reuman Daniel C. 
Published: August 2021

Synchrony among population fluctuations of multiple coexisting species has a major impact on community stability, i.e. on the relative temporal constancy of aggregate properties such as total community biomass. However, synchrony and its impacts are usually measured using covariance methods, which do not account for whether species abundances may be more correlated when species are relatively common than when they are scarce, or vice versa. Recent work showed that species commonly exhibit such ‘asymmetric tail associations’. We here consider the influence of asymmetric tail associations on community stability. We develop a ‘skewness ratio’ which quantifies how much species relationships and tail associations modify stability. The skewness ratio complements the classic variance ratio and related metrics. Using multi-decadal grassland datasets, we show that accounting for tail associations gives new viewpoints on synchrony and stability; e.g. species associations can alter community stability differentially for community crashes or explosions to high values, a fact not previously detectable. Species associations can mitigate explosions of community abundance to high values, increasing one aspect of stability, while simultaneously exacerbating crashes to low values, decreasing another aspect of stability; or vice versa. Our work initiates a new, more flexible paradigm for exploring species relationships and community stability.

Published: August 2021

A novel actinomycete, designated as strain WCH-YHL-001T, was isolated from skin biopsy specimens of a patient at West China Hospital, Chengdu, Sichuan Province, PR China. The cells were Gram-positive, aerobic, heterotrophic and non-motile. They formed an extensive substrate with short aerial mycelia, whose branches fragmented into rod-shaped elements. Growth occurred at 10–40 °C, pH 5.0–12.0 and with NaCl concentrations of 0–4.0 % (w/v). The major cellular fatty acids of strain WCH-YHL-001T were C16 : 0, C18 : 1
ω9c, C18 : 0 10-methyl and summed feature 3. The predominant respiratory quinone was MK-8 (H4ω-cycl). The major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylinositol mannoside, unknown phospholipids and unidentified glycolipids. The diagnostic diamino acid of peptidoglycan was meso-diaminopimelic acid. The whole-cell sugar pattern consisted of arabinose and glucose. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain WCH-YHL-001T belonged to the genus

Nocardia

. The average nucleotide identity (ANI) and in silico DNA–DNA hybridization (isDDH) values between strain WCH-YHL-001T and type strains of

Nocardia

species were lower than the cut-offs (≥95–96 % for ANI and ≥70 % for isDDH) required to define a bacterial species. The genomic DNA G+C content was 67.8 mol%. Phylogenetic, physiological and chemotaxonomic data suggested that strain WCH-YHL-001T represented a novel species of the genus

Nocardia

, for which the name Nocardia huaxiensis sp. nov. is proposed, with the type strain WCH-YHL-001T (=GDMCC 4.181T=JCM 34475 T=NBRC 114973T).

Published: August 2021

AbstractThis study explores the subjective evaluation of supplementary motor area (SMA) regulation performance in a real-time functional magnetic resonance imaging neurofeedback (fMRI-NF) task. In fMRI-NF, people learn how to self-regulate their brain activity by performing mental actions to achieve a certain target level of blood-oxygen-level-dependent (BOLD) activation. This setup offers the possibility to study performance monitoring in the absence of somatosensory feedback. Here, we studied two types of self-evaluation expressed before receiving neurofeedback: performance predictions and perceived confidence in the prediction judgement. We hypothesized that throughout learning, participants would (1) improve the precision of their performance predictions about the actual changes in their BOLD response, and (2) that reported confidence would progressively increase with improved metacognitive precision. Participants completed three sessions of SMA regulation in a 7T fMRI scanner, performing a drawing motor imagery task. During each trial, they modulated their mental drawing strategy to achieve one of two different levels of target fMRI signal change. They then reported a performance prediction and their confidence in the prediction before receiving delayed BOLD-activation feedback. Results show that participants’ performance predictions improved with learning throughout the three sessions, and that these improvements were not driven exclusively by their knowledge of previous performance. Confidence reports on the other hand showed no change throughout training and did not differentiate between the better and worse predictions. In addition to shedding light on mechanisms of internal monitoring during neurofeedback training, these results also point to a dissociation between self-evaluation of performance and corresponding reported confidence in the presence of feedback.
The geometry of normal tissue and cancer gene expression manifolds
Authors: Nieves Joan , Gonzalez Augusto 
Published: August 2021

AbstractA recent paper shows that in gene expression space the manifold spanned by normal tissues and the manifold spanned by the corresponding tumors are disjoint. The statement is based on a two-dimensional projection of gene expression data. In the present paper, we show that, for the multi-dimensional vectors defining the centers of cloud samples: 1. The closest tumor to a given normal tissue is the tumor developed in that tissue, 2. Two normal tissues define quasi-orthogonal directions, 3. A tumor may have a projection onto its corresponding normal tissue, but it is quasi-orthogonal to all other normal tissues, and 4. The cancer manifold is roughly obtained by translating the normal tissue manifold along an orthogonal direction defined by a global cancer progression axis. These geometrical properties add a new characterization of normal tissues and tumors and may have biological significance. Indeed, normal tissues at the vertices of a high-dimensional simplex could indicate genotype optimization for given tissue functions, and a way of avoiding errors in embryonary development. On the other hand, the cancer progression axis could define relevant pan-cancer genes and seems to be consistent with the atavistic theory of tumors.
A study of the reliability of cross-sectional earnings forecasting models for estimating IPO firms’ implied cost of capital
Authors: Schreder Max , Bilinski Pawel 
Published: August 2021

Purpose
This study aims to evaluate the earnings forecasting models of Hou et al. (J Account Econ, 53:504–526, 2012) and Li and Mohanram (Rev Account Stud, 19:1152–1185, 2014) in terms of bias and accuracy and validity of the implied cost of capital (ICC) estimates for a sample of initial public offerings (IPOs).

Design/methodology/approach
The authors use a sample of 1,657 NYSE, Amex and Nasdaq IPOs from 1972 to 2013.

Findings
The models of Hou et al. and Li and Mohanram produce relatively inaccurate and biased earnings forecasts, leading to unreliable ICC estimates, particularly for small and loss-making IPOs that constitute the bulk of new listings. As a remedy, the authors propose a new earnings forecasting model, a combination of Hou et al.’s and Li and Mohanram’s earnings persistence models, and show that it produces more accurate and less biased earnings forecasts and more valid ICC estimates.

Originality/value
The study contributes novel results to the literature on the validity of cross-sectional earnings models in forecasting IPO firm earnings and estimating the ICC. The findings are directly relevant for practitioners, who can improve their earnings forecasting accuracy for IPO firms and related ICC estimates. The insights can be extended to other settings where investors have limited access to financial information, such as acquisitions of private targets.
Drivers of mandatory disclosure in GCC region firms
Authors: Misirlioglu Ismail Ufuk , Tucker Jon , Boshnak Helmi Abdulhameed 
Published: August 2021

PurposeThis paper aims to investigate firm-level variations in the extent of mandatory disclosures and address the drivers of mandatory disclosure using data from the Gulf Co-operation Council (GCC) region.Design/methodology/approachThe extent of mandatory disclosure is examined using a disclosure index created with reference to 24 International Financial Reporting Standards (IFRSs).FindingsThe authors find that the extent of mandatory disclosure required by applicable IFRSs/International Accounting Standards increases with international presence, group firms, the level of voluntary disclosure, firm age and the education level of company financial controllers. It decreases with firm size and the proportion of institutional share ownership. The degree of board independence is positively related to the level of mandatory disclosure in firms with no state ownership. Profitability positively affects the level of mandatory disclosure to a greater extent in more liquid GCC firms. The results confirm that there is a greater sensitivity of mandatory disclosure to loss than to profit. Loss increases, whilst profit decreases, the extent of mandatory disclosure.Research limitations/implicationsThe results promote further understanding of international financial reporting differences in an emerging country setting.Practical implicationsThe findings provide a detailed insight to investors, financial analysts, practitioners and academics.Originality/valueThe authors develop a highly granular mandatory disclosure index in a developing country setting and identify key drivers of such disclosure.

Published: August 2021

PurposeThis paper aims to provide insights into the internationalization strategic responses to the COVID-19 pandemic by higher education institutions (HEIs) in Latin America.Design/methodology/approachThis study is based on information from eight leading Latin American private universities. The data were obtained from official sources such as institutional communications and university administrators.FindingsThe authors identify two main issues that HEIs should consider while responding to the pandemic. First, greater attention and resource allocation to the universities' main local stakeholders can affect traditional internationalization activities. Second, a focus on revitalizing foreign partnerships and strengthening “virtual internationalization” can help maintain and eventually increase international presence.Research limitations/implicationsWhile this study analyses how these Latin American HEIs responded during the initial stages of the COVID-19 outbreak, it is important to conduct follow-up studies to shed light on how HEIs are adapting to the COVID-19 crisis as it continues to unfold.Originality/valueThis study is based on unique information gathered from leading private, not-for-profit HEIs in Latin America, which, contrary to state-owned HEIs or other private institutions in developed economies, have exhibited different means and conditions to respond to the coronavirus outbreak. Finally, the authors contribute to the literature on the internationalization of HEIs by discussing the role of a significant disruptive event on the internationalization of higher education and, particularly, business schools.
How and when frontline employees’ resilience drives service-sales ambidexterity: the role of cognitive flexibility and leadership humility
Authors: Sok Keo Mony , Sok Phyra , Tsarenko Yelena , Widjaja Jason Thomas 
Published: August 2021

Purpose
Service industries increasingly have a need for frontline employees (FLEs) who are both adept and versatile at providing excellent customer services whilst exploring cross-/up-selling opportunities, known as service-sales ambidexterity (SSA). However, engaging in SSA poses various challenges. The purpose of this paper is twofold: First, the authors argue that the resilience of FLEs is a critical factor of their SSA and its effect is mediated by cognitive flexibility. Second, the authors propose a boundary condition – leadership humility – that affects this indirect relationship.

Design/methodology/approach
Survey data was drawn from two independent studies (N = 547). Study 1 was conducted via an online survey of FLEs involved in both service and sales roles in the insurance industry in North America. Data for Study 2 was collected from FLEs working in several branches of a commercial bank operating in Southeast Asia. The data was analysed using Hayes’ PROCESS Macro and SPSS.

Findings
Results from these studies reveal that resilience fosters cognitive flexibility, which, in turn, drives SSA. Additionally, leadership humility was found to moderate the indirect effect of resilience on SSA through cognitive flexibility.

Research limitations/implications
The sample for this study is cross-sectional. Further research could replicate this study using longitudinal data to extract more in-depth information on developmental changes in FLEs. Additionally, the scope of this research is limited to an analysis of employees. However, the phenomenon of SSA is essentially a multi-level subject. Future research could extend the findings of this research by testing other organisational factors that would present a more inclusive framework to explain the SSA phenomenon.

Practical implications
The findings offer managers a new perspective of achieving the alignment between the service and sales goals of their operations.

Originality/value
This study contributes to the growing stream of literature on FLE’s resilience and SSA in particular and shows the role resilience plays in FLEs’ dealing with and navigating a constantly changing workplace where SSA has become a norm rather than an exception.
Managing cancer in contemporary workforces: how employees with cancer and line managers negotiate post-diagnosis support in the workplace
Authors: Remnant Jennifer 
Published: August 2021

PurposeThis paper explores how deservingness features in how line managers and employees with cancer negotiate post-diagnosis support in the workplace.Design/methodology/approachIt draws on narrative interview data from people with cancer in the UK who were employed when diagnosed and line managers with experience of managing an employee with cancer. Semi-structured interviews were conducted with members of occupational health and human resources staff and staff from a UK cancer support charity.FindingsIt shows that post-diagnosis support for employees with cancer was negotiated in subjective, individualised ways, drawing on pre-diagnosis workplace contribution as well as the perceived deservingness of cancer as an illness. Managerial support for employees with cancer was also influenced by post-diagnosis employee behaviours, particularly those that implied a readiness to return to work.Research limitations/implicationsThe sample size and methods limit the generalisability of the results. However, sampling choices were instrumental in reaching a rich set of data, which enabled deeper understanding of individual workplace negotiations.Social implicationsPervasive and unhelpful notions of deservingness in the context of ill-health and disability have distinct and worrying implications for ageing workforces, particularly across the Global North. This has been exacerbated by the ongoing uncertainty and insecurity triggered by the coronavirus disease 2019 (COVID-19) pandemic. As a result insight into the management of ill-health at work has never been more relevant, and can be used to inform policy and practice.Originality/valueThis exploratory paper extends debates usually reserved for social welfare and health provision to a new domain by exploring how deservingness features in line manager–employee interactions in the context of an employee diagnosis of cancer.
Promoting entrepreneurship based on university students' perceptions of entrepreneurial attitude, university environment, entrepreneurial culture and entrepreneurial training
Authors: Valencia-Arias Alejandro , Arango-Botero Diana , Sánchez-Torres Javier A. 
Published: August 2021

PurposeThe purpose of this study is to verify some relationships between entrepreneurial attitude, university environment, entrepreneurial culture and entrepreneurial training, which can be used to promote entrepreneurship among university students.Design/methodology/approachA sample of 3,005 questionnaires answered by students from ten universities in Colombia was gathered and partial least squares structural equation modelling (PLS-SEM) was used for the analysis.FindingsThe results show that the more a student perceives an entrepreneurial culture and the more training he or she receives, the more entrepreneurial attitude he or she will have. Also, it was found that entrepreneurial culture has a positive effect on university environment, and the latter has a positive effect on entrepreneurial training.Research limitations/implicationsThe main limitation of this study was that only ten Colombian universities were sampled; therefore, general inferences cannot be made. Additionally, the variables investigated here may have not accurately measured the full scale of the entrepreneurship programmes in such universities or the way the culture of these institutions had a direct impact on students. Projects such as the Global University Entrepreneurial Spirit Students' Survey (GUESSS), which measure variables related to entrepreneurship at the university level, enable universities to shape their policies around this important topic. This study indicates that universities should offer training in entrepreneurial, problem-solving and communication skills to produce entrepreneurs who can better face current challenges.Originality/valueOther studies have discussed entrepreneurial culture, but they usually deal with university environment, entrepreneurial training and entrepreneurial attitudes separately. This study integrates all these factors and measures the level of interaction between them.
