Risk stratification using non-invasive liver stiffness surveillance and collagen proportionate areas
Authors: Chen Sheng-Hung
Published: June 2021

Unlike other organs in the human body, the liver is able to regenerate, replacing and repairing damaged tissue and leaving no scar tissue. However, when a liver is repeatedly damaged, liver fibrosis can occur and large amounts of scar tissue are formed. Scarring of the liver caused
by long-term liver damage is called cirrhosis and this is a major cause of death around the world. It's important that liver fibrosis can be assessed in patients using non invasive methods, which are of course preferable to invasive methods. The goal of the research of Associate Professor
Sheng-Hung Chen, Center for Digestive Medicine, China Medical University Hospital, Taiwan, is to help improve the effectiveness of treatments and outcomes for a range of diseases, including hepatitis. He is working to conduct risk stratification using non-invasive liver stiffness and collagen
proportionate areas. Liver fibrosis monitoring over time is a critical issue and the development of non-invasive methods for liver fibrosis monitoring as well as other ways of understanding the condition of a patient's liver could facilitate the prognostics and save lives. Chen and the team
are seeking to predict liver-related events over time by working on the concurrent kinetics in clinical aspects, paired or serial liver histology, blood test-based results and stiffness measurement.
Identification and Reporting of Patient and Public Partner Authorship on Knowledge Syntheses: Rapid Review (Preprint)
Authors: Ellis Ursula , Kitchin Vanessa , Vis-Dunbar Mathew
Published: June 2021

BACKGROUND

Patient and public involvement (PPI) in health research is an area of growing interest. Several studies have examined the use and impact of PPI in knowledge syntheses (systematic, scoping, and related reviews); however, few studies have focused specifically on the patient or public coauthorship of such reviews.

OBJECTIVE

This study seeks to identify published systematic and scoping reviews coauthored by patient or public partners and examine the characteristics of these coauthored reviews, such as which journals publish them, geographic location of research teams, and terms used to describe patient or public partner authors in affiliations, abstracts, or article text.

METHODS

We searched CAB Direct, CINAHL, Cochrane Database of Systematic Reviews (Ovid), Embase (Ovid), MEDLINE (Ovid), and PsycInfo from 2011 to May 2019, with a supplementary search of several PPI-focused databases. We refined the Ovid MEDLINE search by examining frequently used words and phrases in relevant search results and searched Ovid MEDLINE using the modified search strategy in June 2020.

RESULTS

We screened 13,998 results and found 37 studies that met our inclusion criteria. In line with other PPI research, we found that a wide range of terms were used for patient and public authors in author affiliations. In some cases, partners were easy to identify with titles such as patient, caregiver or consumer representative, patient partner, expert by experience, citizen researcher, or public contributor. In 11% (n=4) of studies, they were identified as members of a panel or advisory council. In 27% (n=10) of articles, it was either impossible or difficult to tell whether an author was a partner solely from the affiliation, and confirmation was found elsewhere in the article. We also investigated where in the reviews the partner coauthors’ roles were described, and when possible, what their specific roles were. Often, there was little or no information about which review tasks the partner coauthors contributed to. Furthermore, only 14% (5/37) of reviews mentioned patient or public involvement as authors in the abstract; involvement was often only indicated in the author affiliation field or in the review text (most often in the methods or contributions section).

CONCLUSIONS

Our findings add to the evidence that searching for coproduced research is difficult because of the diversity of terms used to describe patient and public partners, and the lack of consistent, detailed reporting about PPI. For better discoverability, we recommend ensuring that patient and public authorships are indicated in commonly searched database fields. When patient and public-authored research is easier to find, its impact will be easier to measure.
Associations Between the Perceived Severity of the COVID-19 Pandemic, Cyberchondria, Depression, Anxiety, Stress, and Lockdown Experience: Cross-sectional Survey Study (Preprint)
Authors: Han Lei , Zhan Yanru , Li Weizi , Xu Yuqing , Xu Yan , Zhao Jinzhe
Published: June 2021

BACKGROUND

The outbreak of the COVID-19 pandemic has caused great panic among the public, with many people suffering from adverse stress reactions. To control the spread of the pandemic, governments in many countries have imposed lockdown policies. In this unique pandemic context, people can obtain information about pandemic dynamics on the internet. However, searching for health-related information on the internet frequently increases the possibility of individuals being troubled by the information that they find, and consequently, experiencing symptoms of cyberchondria.

OBJECTIVE

We aimed to examine the relationships between people’s perceived severity of the COVID-19 pandemic and their depression, anxiety, and stress to explore the role of cyberchondria, which, in these relationship mechanisms, is closely related to using the internet. In addition, we also examined the moderating role of lockdown experiences.

METHODS

In February 2020, a total of 486 participants were recruited through a web-based platform from areas in China with a large number of infections. We used questionnaires to measure participants’ perceived severity of the COVID-19 pandemic, to measure the severity of their cyberchondria, depression, anxiety, and stress symptoms, and to assess their lockdown experiences. Confirmatory factor analysis, exploratory factor analysis, common method bias, descriptive statistical analysis, and correlation analysis were performed, and moderated mediation models were examined.

RESULTS

There was a positive association between perceived severity of the COVID-19 pandemic and depression (β=0.36, t=8.51, P<.001), anxiety (β=0.41, t=9.84, P<.001), and stress (β=0.46, t=11.45, P<.001), which were mediated by cyberchondria (β=0.36, t=8.59, P<.001). The direct effects of perceived severity of the COVID-19 pandemic on anxiety (β=0.07, t=2.01, P=.045) and stress (β=0.09, t=2.75, P=.006) and the indirect effects of cyberchondria on depression (β=0.10, t=2.59, P=.009) and anxiety (β=0.10, t=2.50, P=.01) were moderated by lockdown experience.

CONCLUSIONS

The higher the perceived severity of the COVID-19 pandemic, the more serious individuals’ symptoms of depression, anxiety, and stress. In addition, the associations were partially mediated by cyberchondria. Individuals with higher perceived severity of the COVID-19 pandemic were more likely to develop cyberchondria, which aggravated individuals’ depression, anxiety, and stress symptoms. Negative lockdown experiences exacerbated the COVID-19 pandemic’s impact on mental health.
SPECIES IDENTIFICATION FOR AQUATIC BIOMONITORING USING DEEP RESIDUAL CNN AND TRANSFER LEARNING
Authors: Milosavljević Aleksandar , Milošević Đurađ , Predić Bratislav
Published: June 2021

Aquatic insects and other benthic macroinvertebrates are mostly used as bioindicators of the ecological status of freshwaters. However, an expensive and time-consuming process of species identification represents one of the key obstacles for reliable biomonitoring of aquatic ecosystems. In this paper, we proposed a deep learning (DL) based method for species identification that we evaluated on several available public datasets (FIN-Benthic, STONEFLY9, and EPT29) along with our Chironomidae dataset (CHIRO10). The proposed method relies on three DL techniques used to improve robustness when training is done on a relatively small dataset: transfer learning, data augmentation, and feature dropout. We applied transfer learning by employing ResNet-50 deep convolutional neural network (CNN) pretrained on ImageNet 2012 dataset. The results show significant improvement compared to original contributions and confirms that there is a considerable gain when there are multiple images per specimen.
GENERATING KNOWLEDGE STRUCTURES FROM OPEN DATASETS' TAGS - AN APPROACH BASED ON FORMAL CONCEPT ANALYSIS
Authors: Bogdanović Miloš , Frtunić Gligorijević Milena , Veljković Nataša , Stoimenov Leonid
Published: June 2021

Under influence of data transparency initiatives, a variety of institutions have published a significant number of datasets. In most cases, data publishers take advantage of open data portals (ODPs) for making their datasets publicly available. To improve the datasets' discoverability, open data portals (ODPs) group open datasets into categories using various criteria like publishers, institutions, formats, and descriptions. For these purposes, portals take advantage of metadata accompanying datasets. However, a part of metadata may be missing, or may be incomplete or redundant. Each of these situations makes it difficult for users to find appropriate datasets and obtain the desired information. As the number of available datasets grows, this problem becomes easy to notice. This paper is focused on the first step towards decreasing this problem by implementing knowledge structures to be used in situations where a part of datasets' metadata is missing. In particular, we focus on developing knowledge structures capable of suggesting the best match for the category where an uncategorized dataset should belong to. Our approach relies on dataset descriptions provided by users within dataset tags. We take advantage of a formal concept analysis to reveal the shared conceptualization originating from the tags' usage by developing a concept lattice per each category of open datasets. Since tags represent free text metadata entered by users, in this paper we will present a method of optimizing their usage through means of semantic similarity measures based on natural language processing mechanisms. Finally, we will demonstrate the advantage of our proposal by comparing concept lattices generated using formal the concept analysis before and after the optimization process. The main experimental research results will show that our approach is capable of reducing the number of nodes within a lattice more than 40%.
A DISCRETE ELEMENT FORMALISM FOR MODELLING WEAR PARTICLE FORMATION IN CONTACT BETWEEN SLIDING METALS
Authors: Shilko Evgeny V. , Grigoriev Aleksandr S. , Smolin Alexey Yu.
Published: June 2021

The paper describes an advanced discrete-element based mechanical model, which allows modelling contact interaction of ductile materials with taking into account fracture and surface adhesion by the cold welding mechanism. The model describes these competitive processes from a unified standpoint and uses plastic work of deformation as a criterion of both local fracture and chemical bonding of surfaces in contact spots. Using this model, we carried out a preliminary study of the formation of wear particles and wedges during the friction of rough metal surfaces and the influence of the type of forming third body (interfacial) elements on the dynamics of the friction coefficient. The qualitative difference of friction dynamics in the areas of the contact zone characterized by different degrees of mechanical confinement is shown.
FRICTION UNDER LARGE-AMPLITUDE NORMAL OSCILLATIONS
Authors: Popov Mikhail
Published: June 2021

Building on a recently proposed contact-mechanical theory of friction control by external vibration, the case of large-amplitude normal oscillation is revisited. It is shown that the coefficient of friction can be expressed in particularly simple form if the waveform of the displacement oscillation is triangular or rectangular, and the contact stiffness is constant. The latter requirement limits the scope of the exact solutions to contacts between a plane and a flat-ended cylinder or a curved shape with a wear flat, but the adopted methodology also enables efficient numerical solution in more general cases.
A RIGOROUS MODEL FOR FREQUENCY-DEPENDENT FINGERPAD FRICTION UNDER ELECTROADHESION
Authors: Forsbach Fabian , Heß Markus
Published: June 2021

In the electroadhesive frictional contact of a sliding fingerpad on a touchscreen, friction is enhanced by an induced electroadhesive force. This force is dominated by the frequency-dependent impedance behavior of the relevant electrical layers. However, many existing models are only valid at frequency extremes and use very simplified contact mechanical approaches. In the present paper, a RC impedance model is adopted to characterize the behavior in the relevant range of frequencies of the AC excitation voltage. It serves as an extension to the macroscopic model for electrovibration recently developed by the authors, which is based on several well-founded approaches from contact mechanics. The predictions of the extended model are compared to recent experimental results and the most influential electrical and mechanical parameters are identified and discussed. Finally, the time responses to different wave forms of the excitation voltage are presented.
BUBBLE DYNAMICS-BASED MODELING OF THE CAVITATION DYNAMICS IN LUBRICATED CONTACTS
Authors: Geike Thomas
Published: June 2021

Cavitation is a common phenomenon in fluid machinery and lubricated contacts. In lubricated contacts, there is a presumption that the short-term tensile stresses at the onset of bubble formation have an influence on material wear. To investigate the duration and magnitude of tensile stresses in lubricating films using numerical simulation, a suitable simulation model must be developed. The chosen simulation approach with bubble dynamics is based on the coupling of the Reynolds equation and Rayleigh-Plesset equation (introduced about 20 years ago by Someya).Following the basic approach from the author’s earlier papers on the negative squeeze motion with bubble dynamics for the simulation of mixed lubrication of rough surfaces, the paper at hand shows modifications to the Rayleigh-Plesset equation that are required to get the time scale for the dynamic processes right. This additional term is called the dilatational viscosity term, and it significantly influences the behavior of the numerical model.
POSITIVE VIEWS AND CHALLENGES OF USING PROJECT WORK IN ESP LESSONS
Authors: Kovacikova Elena , Kralova Zdena
Published: June 2021

ESP lessons in higher education develop foreign language competences of university students and prepare them for their professional lives. This paper brings views of university students on using projects in the classroom within their ESP lessons. As a part of the research through methods of focus groups, their analyses, the results and interpretations uncover positive and negative sides of using projects in ESP classroom from students’ points of views. The results show that project work on the one hand strengthens and builds responsibility for learning and thus leads towards autonomous learning as one of the educational objectives of 21st century schooling. On the other hand, the research shows that the students see themselves as they are still not ready to take over responsibility for their own learning, they do not feel competent to give presentations, feel anxious to speak a foreign language in public and do not see themselves competent enough to develop their own projects in foreign languages within the topics of their future professions even though their language level reaches B1 level according to CEFR. Interpretation of these findings show insufficient or ineffective use of projects in earlier educational level, not enough attention given to development of productive skills and confidence in a foreign language use.

INTERSUBJECTIVE APPROACH TO PRE-TRANSLATION ANALYSIS OF ARCHITECTURAL CRITICISM: REACHING AFTER THE BALANCE
Authors: Latysheva Svetlana
Published: June 2021

The study discusses a new approach to translation of architectural critical materials focusing on the stage of source texts analysis. Architecture synthesizes science, technology, art and social sphere resulting in the heterogeneity of translatological characteristics of texts representing architectural phenomena. They combine the parameters of institutional and personal discourse possessing the features of specialized texts, such as the predominance of cognitive information and a high degree of conventionality, and artistic texts with their emotional, aesthetic and axiological aspects. This functional ambivalence limits the use of traditional methods based on genre or stylistic analysis. This research is an attempt to develop a new approach to pre-translation analysis of architectural texts yielding adequate translation methods for architectural nominations and contributing to the retainment of original text identity. The study views intersubjectivity in pre-translation analysis as conceptual coordination within the discourse of the expert community carried out in the process of interaction between authors of source texts and addressees of translation texts through interlingual mediation. The developed method allows translators to reveal relevant cognitive and discursive parameters of nominations of architectural phenomena at various language levels. In addition, it reveals the translation dominants that assist both to preserve the sufficient level of translation text conventionality within the institutional discourse of architecture and to transfer personal meanings and values implied by source text authors within their personal discourse.
TEACHING NOUN-PHRASE COMPOSITION IN EAP/ESP CONTEXT: A CORPUS-ASSISTED APPROACH TO OVERCOME A DIDACTIC GAP
Authors: Malakhovskaya Maria , Beliaeva Larisa , Kamshilova Olga
Published: June 2021

Attributive noun phrases, namely noun + noun constructions (NNCs), is an essential typological characteristic of academic style. However, errors in their production and use are not uncommon even in the writing of advanced Russian users of academic English. As such errors slow down reading and, in some cases, lead to misinterpretations, they may be a hindrance to the publication of research results in international journals. Aiming at facilitating NNC instruction, the study focuses on linguistic and didactic aspects of this construction. It highlights NNC complexity and a lack of consensus among researchers as to their linguistic status and semantic nature. The research demonstrates that NNCs do not find proper interpretation in EAP/ESP teaching literature, which results in their misuse by non-native English contributors to international scientific journals. Based on some published practice and personal experience in teaching academic skills, the research lays down a corpus-assisted approach to teaching students to master the grammar and use of NNCs in their own discipline texts. The principal advantage of this approach is that it provides students with patterns of NNP expert use and aids EAP/ESP instructors to develop discipline-specific didactic materials based on reliable and up-to-date facts on generating NNCs.
HOW CAN AND SHOULD TRANSLATION TEACHERS BE TRAINED?
Authors: Petrova Olga , Sdobnikov Vadim
Published: June 2021

The need to train a large number of translators necessitates the training of professional translation teachers. At present, translation is taught either by translators having no pedagogical education or by teachers of foreign languages with no degree and often no practical experience in translation. Both categories need additional training that would supplement their education. The existing system of short-time professional development courses is not adequate to the task of filling in the gaps in professional education of translation teachers. The article discusses a conceptually new approach to retraining and training translation teachers that presupposes developing and introducing several type programs. They are extensive retraining programs for those who currently teach translation and two types of master’s degree programs for students having a bachelor’s degree either in translation or in teaching foreign languages. In both types of programs, the pedagogical and translation components of education will supplement each other, so that graduates will acquire competences necessary for being good translation teacher. Special emphasis should be laid on translation didactics which so far has not been taught either in translator training programs or in teacher training programs of any type or level. The authors discuss principles of designing and developing such programs.
GENERAL ENGLISH AND MORE OR LESS TECHNICAL ESP ON THE EXAMPLE OF WORD LISTS
Authors: Đurović Zorica , Vuković Stamatović Milica
Published: June 2021

The renewed interest in vocabulary research, especially due to its meaning-carrying significance in technical Englishes, has cleared the way to the development of corpus linguistics methods based on real-life texts. As the learning/teaching of general English leads towards the learning/teaching of English for a Specific Purpose (in line with the learner’s needs), so the creation of general English word lists imposes the creation of technical word lists, aiming to achieve a desired level of the target corpus comprehension. In this paper, we discuss the common grounds and specifics of various levels of general and technical English in terms of their lexical coverage of texts, specifically addressing the example of marine engineering technical manuals.
SYSTEMATIC RESEARCH SYNTHESIS ON RATING IN ESP SPEAKING ASSESSMENTS
Authors: Hijikata Yuko , Min Jiyu
Published: June 2021

Jacoby and McNamara (1998) insist that domain specialists (e.g., doctors) and language specialists (e.g., teachers) differ in their approaches to evaluating profession-specific communication tasks. However, due to the scarcity of studies examining speaking assessments for occupational purposes, the differences between the two rater groups have not yet been clearly revealed. In response to this gap in the literature, this systematic research synthesis study examines how the workplace speaking skill has been evaluated, focusing on rater groups and rating scales. The major findings are as follows. First, research on ESP speaking assessments tends to include more than one rater group such as domain specialists and language specialists. Second, while domain specialists and language specialists generally demonstrate high intergroup correlations, the rater group notably differs in terms of field-specific criteria. Third, compared with linguistic scales, field-specific criteria have not been developed. Based on these results, directions for future research are discussed.
LEGAL FRAMEWORK OF OCCUPATIONAL SAFETY AND HEALTH POLICY IN THREE SOUTH EASTERN COUNTRIES
Authors: Ilić Petković Aleksandra
Published: June 2021

The legal framework for occupational safety and health is a key factor in effective policy implementation in this area at the local level. Employees in local self-government units perform tasks of immediate interest for the local population and, because of that, their workplace safety and health is an important issue. Given that there is not much research on the safety and health of employees in local self-government units in the countries of Southeast Europe, there is a need for the analysis of the protection provided by the applicable regulations. The conducted research shows that this category of employees is not specifically recognized either in the regulations on occupational safety and health or in the regulations on local self-government. It is desirable to improve the quality of legal protection which will contribute to the improvement of the workplace safety and health of these employees and will improve the quality of work in local self-governments.

Variational quantum solver employing the PDS energy functional
Authors: Peng Bo , Kowalski Karol
Published: June 2021

Recently a new class of quantum algorithms that are based on the quantum computation of the connected moment expansion has been reported to find the ground and excited state energies. In particular, the Peeters-Devreese-Soldatov (PDS) formulation is found variational and bearing the potential for further combining with the existing variational quantum infrastructure. Here we find that the PDS formulation can be considered as a new energy functional of which the PDS energy gradient can be employed in a conventional variational quantum solver. In comparison with the usual variational quantum eigensolver (VQE) and the original static PDS approach, this new variational quantum solver offers an effective approach to navigate the dynamics to be free from getting trapped in the local minima that refer to different states, and achieve high accuracy at finding the ground state and its energy through the rotation of the trial wave function of modest quality, thus improves the accuracy and efficiency of the quantum simulation. We demonstrate the performance of the proposed variational quantum solver for toy models, H2 molecule, and strongly correlated planar H4 system in some challenging situations. In all the case studies, the proposed variational quantum approach outperforms the usual VQE and static PDS calculations even at the lowest order. We also discuss the limitations of the proposed approach and its preliminary execution for model Hamiltonian on the NISQ device.

La investigación en enfermería suele agregar una base teórica, que ayude a comprender la realidad de un fenómeno presente en esta disciplina; sin embargo, en ocasiones las teorías existentes, no tienen los elementos necesarios para la exploración de algunos fenómenos, por lo que se debe optar por realizar una derivación teórica que contenga los atributos necesarios para el desarrollo de una investigación. Desde este punto de vista con el presente trabajo se pretende desarrollar una derivación teórica, a partir de la teoría de la autotrascendencia, para abordar el fenómeno de la espiritualidad y la calidad de vida en el adulto mayor. Al respecto la metodología a tener en cuenta se desarrolla a partir de los aportes de Jaqueline Fawcett, quien integra cinco pasos necesarios para explicar los conceptos, proposiciones y relaciones sobre su derivación teórica. Además, se exhorta a que se tome en cuenta esta propuesta en próximas investigaciones, para que se pueda probar su efectividad.

Objetivos: El objetivo de este proyecto de investigación se basó en identificar los factores asociados a la estancia hospitalaria prolongada en una institución de mediana y alta complejidad de Medellín. Materiales y métodos: Se realizó un estudio analítico, cuantitativo, de corte transversal; con una selección aleatoria simple de pacientes registrados en el consolidado de estancia hospitalaria prolongada en la institución objeto de estudio, donde (n =291) pacientes; para el análisis bivariado se utilizó x2 cuadrado en SPSS, los valores P arrojados fueron evaluados con un nivel de confianza del 95% y un margen de error del 5%, dando un nivel de significancia o de valor alfa de 0.05 de los 291 registros analizados. Resultados: se encontró asociación estadísticamente significativa entre estancia hospitalaria prolongada y atención domiciliaria (p= 0,028); procedimientos: (p= 0.046) y ayudas diagnósticas: (p= 0,38). Conclusiones: La estancia hospitalaria de un paciente, no solo depende de su condición clínica; depende de una interrelación entre otros actores en su atención, institución, prestador y red de servicios.

Published: June 2021

El siguiente artículo teórico presenta un modelo desarrollado mediante análisis cualitativo de contenido con cinco dimensiones: a) jugabilidad intrínseca – técnica, b) jugabilidad mecánica, c) jugabilidad interactiva – interpersonal, d) jugabilidad artística – intrapersonal y e) didáctica - prácticas científicas. El objetivo es identificar juegos
de ordenador que presenten potencialidades para la enseñanza de las ciencias de la naturaleza y que fortalezcan prácticas científicas y habilidades socioemocionales. Así mismo, se discuten las prácticas científicas, los videojuegos como herramientas de aprendizaje en el marco de la cognición situada, la teoría de flujo de Csikszentmihalyi, el modelo de Marczewski y, finalmente, las habilidades socioemocionales.
Se constituye en una contribución de interés para identificar las potencialidades de los videojuegos a los fines de determinar cuáles resultan más potentes al momento de diseñar situaciones y actividades didácticas para la enseñanza de las ciencias de la naturaleza.

All vulvar malignancies comprise only 2% of vulvar lesions, since 98%
of vulvar neoplasms are benign. Nodular Fasciitis of the vulva present a
diagnostic dilemma due in part to the rare nature of these disorders and
similarities malignant soft tissue tumors, so publishing descriptions of
these entities are essential
Monitoraggio delle emissioni odorigene in un piccolo impianto di depurazione attraverso un approccio senso-strumentale.
Authors: Russo Federica , Giaquinto Domenico
Published: June 2021

Le molestie olfattive indotte da impianti di trattamento di acque reflue
costituiscono un vero e proprio problema ambientale. In particolare, le
emissioni odorigene derivanti dall’esercizio di impianti in zone
turistiche sono considerate la principale causa di disturbo notato dalla
popolazione esposta. La valutazione dell’impatto indotto può essere
effettuata attraverso la misurazione degli odori, utilizzando un metodo
analitico o sensoriale. Quest’ultimo, legato al “sensore umano” è
causa di notevole incertezza. Pertanto, nel presente articolo si vuole
mostrare l’applicazione di una procedura innovativa di tipo
senso-strumentale, il cui obiettivo è quello di rimuovere la componente
soggettiva nella misura degli odori. I risultati ottenuti in uno SWWTP
hanno dimostrato l’applicabilità di tale procedura nel monitoraggio
delle emissioni odorigene ed hanno permesso l’identificazione di 39
sostanze diverse di cui quasi la metà responsabili di disturbi
olfattivi.
New regular numeral symbols from one to septillion
Authors: Qin Yiren , Cao Guangrui
Published: June 2021

Some iconic symbols representing numbers are more animated, picturesque,
and impressive. Here we describe a kind of new numeral symbols from one
to septillion. These symbols are regular and simple. Meanwhile it is
easy to write and remember these number symbols. They are composed of 27
basic components. After these basic components are regularly combined,
simple and effective numeral symbols from one to septillion can be
generated. They might be used in games, movies, animations, computer
science and even in other arts.

Obstetric anal sphincter injury by maternal origin and length of residence: a nation-wide cohort study
Authors: Sorbye Ingvil , Bains Sukhjeet , Vangen Siri , Sundby Johanne , Lindskog Benedikte , Owe Katrine
Published: June 2021

Objective: To estimate the association between maternal origin and
obstetric anal sphincter injury (OASI), and assess if associations
differed by length of residence. Design: Population-based cohort study.
Setting: The Medical Birth Registry of Norway. Population: Primiparous
women with vaginal livebirth of a singleton cephalic fetus between 2008
and 2017 (n=188 658). Methods: Multivariable logistic regression models
estimated aORs for OASI with 95% CI by maternal region of origin and
birthplace. We stratified models on length of residence and paternal
birthplace. Main outcome measures: OASI. Results: Overall 6 373 cases of
OASI were identified (3.4% of total cohort). Women from South Asia were
most likely to experience OASI (6.2%; aOR 2.24, 95% CI 1.93–2.60),
followed by those from Southeast/East Asian/Pacific (5.7%; 1.83,
1.64–2.04), and Sub-Saharan Africa (5.2%; 1.97, 1.72–2.26), compared
to women originating from Norway. Among women born in the same region,
those with short length of residence in Norway (0–4 years), showed
higher odds of OASI. Migrant women across most regions of origin had
reduced risk of OASI if they had a Norwegian compared to foreign-born
partner. Conclusions: Primiparous women from Asian regions and
Sub-Saharan Africa had up to two-fold risk of OASI, compared to women
originating from Norway. Migrants with short residence and those with a
foreign-born partner had higher risk of OASI, implying that some of the
risk differential is due to sociocultural factors. Some migrants,
especially new arrivals, may benefit from special attention during
labour to reduce morbidity and achieve equitable outcomes.

Published: June 2021

This article summarizes and reflects on the implications of the published study “Employee Satisfaction and Work-Life Balance in Accounting Firms and Audit Quality” (Khavis and Krishnan 2021), which examines the link between employee satisfaction, work-life balance, and audit quality within accounting firms. The study uses employee-level reviews from Glassdoor.com to examine how accounting firms are perceived by their employees, and tests whether accounting firms' workplace characteristics explain employee satisfaction and audit quality. We briefly summarize the findings of this study and highlight relevant practical implications related to audit quality, employee recruitment, and employee retention, which may interest practitioners, regulators, and academics.
