The effect of the COVID-19 on sharing economy: survival analysis of Airbnb listings
Authors: Türk Umut , Sap Serap 
Published: March 2021

This research investigates the survival probability of listings in the Airbnb platform during the COVID-19 period between January-October 2020 in Istanbul. In line with the research aim, Cox's Proportional Hazard Model is adopted to conduct survival analysis, where the physical and spatial attributes of Airbnb listings are used as predictors. Our findings show that while physical attributes show similarity to previous findings, spatial attributes show substantial differences in the Pre-COVID and Post-COVID comparison. The contributions of the study have two facets. Theoretically, this research's findings contribute to the current literature by understanding the changing consumer preferences and identifying the factors that affect Airbnb listings' survival rates during the COVID-19 pandemic. The findings may also help practitioners understand changing customers' preferences during COVID, especially in terms of locational choices. Moreover, customer feedback's quality and quantity might help the Airbnb hosts to improve their service quality, attract more customers, and be more resilient under the changing conditions.
Conditions for Successful Active Investment in Terms of the State and the Far-sighted Interests of the Business
Authors: Vasylenko Yuriy 
Published: March 2021

For the macro characteristic of active investment, we introduced the concept of the technical productivity of investment. It characterizes an investment’s capacity to reduce the norm of material or labor costs.Based on the technical productivity of investment, we derived the equation (not identity) of economic dynamics.We have proposed measuring the efficiency of investments by added-value to reflect their effectiveness for the business owner’s far-sighted interests in minimizing the turnover of skilled workers. We have proposed to use the criteria in terms of the state – the maximum of the real GDP growth and the maximum of the sum of real GDP for the country as a whole.We defined the limits of an investment’s technical productivity, for which the investor receives the desired payback or effectiveness, and an economy in maximal development.For this, we used our causal simulation model of Ukraine’s economy dynamics, which, in contrast to the known models, reflects the main types of legal and shadow economic activities in their relationships.

Published: March 2021

BACKGROUND AND OBJECTIVES:
Transgender adolescents experience disproportionately high rates of dating violence and peer victimization. However, research has relied on small samples of transgender youth and has not captured victimization experiences of gender-expansive youth (who do not identify as male, female, or transgender). In the current study, we address these limitations, comparing victimization by gender.

METHODS:
We examined a subsample of 4464 male, female, transgender, and gender-expansive youth (1116 per group) from the 2018 Illinois Youth Survey who were frequency matched on grade, race, geographic region, and free or reduced lunch status. Prevalence of self-reported verbal, physical, and cyber peer victimization and physical and psychological dating violence was calculated. Adjusted prevalence ratios were obtained by using log-binomial regression.

RESULTS:
The highest rates across all forms of victimization were reported among transgender (15.6%–51.6%) and gender-expansive (13.2%–41.4%) youth. Transgender youth had a 2.09 to 2.96 times higher frequency of victimization than male youth and a 1.34 to 2.65 times higher frequency of victimization than female youth. Transgender youth also had higher frequencies of specific forms of victimization than gender-expansive youth. Gender-expansive youth had a 1.83 to 2.61 times higher frequency of victimization than male youth and 1.18 to 2.35 times higher frequencies of most forms of victimization than female youth.

CONCLUSIONS:
Disparities in dating violence and peer victimization rates exist among transgender and gender-expansive adolescents compared with male and female youth. The distinct experiences of transgender and gender-expansive youth should be considered in school policies and violence prevention programs.

Published: March 2021

BACKGROUND:
The Community Asthma Initiative (CAI) was included in the New England Asthma Innovations Collaborative, which received a Centers for Medicare and Medicaid Services (CMS) Innovation grant. Under this grant, CAI transitioned from a mixed community health worker and nurse model to a nurse-supervised community health worker model. CMS limited enrollment to patients with Medicaid and encouraged 3 home visits per family.

METHODS:
A total of 389 patients enrolled under the CMS grant at Boston Children’s Hospital from 2013 to 2015 (CMS group) were compared with 733 CAI patients with Medicaid enrolled from 2005 to 2012 (comparison group). Changes in 5 asthma-related measures (emergency department visits, hospitalizations, physical activity limitations, missed school days, and parent and/or guardian missed workdays) were compared between baseline and 6 and 12 months postenrollment. Measures were analyzed as dichotomous variables using logistic regression. Numbers of occurrences were analyzed as continuous variables. Changes in quality of life (QoL) among the CMS group were examined through a 13-question survey with activity and emotional health subscales.

RESULTS:
Although patients in both groups exhibited improvement in all measures, the CMS group had greater odds of decreased hospitalizations (odds ratio 3.13 [95% confidence interval 1.49–6.59]), missed school days (1.91 [1.09–3.36]), and parent and/or guardian missed workdays (2.72 [1.15–6.41]) compared to the comparison group. Twelve months postenrollment, the CMS group experienced improvement in all QoL questions and subscales (all P values &lt;.01).

CONCLUSIONS:
The CMS group showed improved outcomes for hospitalizations and missed school and workdays compared to the comparison group. The CMS group also exhibited significant improvement in QoL.

Published: March 2021

Abstract
Aims: This study was conducted to investigate the presence of thecombination of Demodex folliculorum and aerobic bacteria in patients with chronic blepharitis.
Material and Methods: Seventy-one patients diagnosed with chronic blepharitis were evaluated for the presence of D. folliculorumby light microscope examination of samples prepared from eyelashes collected by eyelash epilation. Culture samples were also obtained from patients’ eyelid margins. Bacterial strainsamong the predominant bacterial colonies grown in cultures were identified using the BD Phoenix identification system (BD Diagnostic Systems, Sparks, USA). Patients were divided into two groups, Demodex-positive and Demodex-negative,and compared according to bacterial production and bacterial strains produced.
Results: D. folliculorumwas identified in 42 (59.1%) patients. Comparison between Demodex-positive and -negative groups revealeda statistically significant increase in Demodex positivity with age.There was no significant relationship between gender and Demodex positivity.The Demodex-positive group showed a statistically significantly higher bacterial growth in the culture samples than the Demodex-negative group.Both groups exhibited a predominance ofStaphylococcus epidermidis. S.epidermidis (38.1% vs. 31.0%), Staphylococcus aureus (19.0% vs. 10.3%), and Corynebacterium spp.(16.7% vs. 6.9%) were detected at higher rates in the Demodex-positive group than in the Demodex-negative group. There was no statistically significant difference between both groups regarding the presence of these bacterial species.
Conclusions: Patients with chronic blepharitis could have a mixedinfection site with the combination of D. folliculorumand aerobic bacteria found in the normal eyelid flora.

Published: March 2021

Coronaviruses are a family of viruses present in various animals, and alpha and beta types can infect humans. Human coronavirus varieties settle in different regions of the respiratory tract epithelium, causing disease with varying severity. We conducted a comprehensive academic search to aggregate data and added our own ideas to create a good research article. As a result of many studies carried out in a short time, detailed information was obtained about the entry of the virus into the cell and its cellular cycle.
Although vaccination studies are about to come to an end, we do not yet have an agent that provides a definitive treatment that will facilitate millions of people's lives. At this point, humanity needs detailed genetic research, especially on cellular interactions.
Because although we think that we are in control of the subject, science is a field that changes daily, and new data are added to it. It is evident that we need marginal ideas for a virus that has affected the whole world, can easily be transmitted by respiratory and droplets, and has destroyed everyday life. This research aims to examine the data we have so far in detail on all of the topics we have mentioned and try to make some suggestions within our knowledge.

Objective: This study was conducted to determine the correlation between vitamin D level and pain, functional status, and quality of life in individuals with osteoarthritis (OA).
Material and Method: This cross-sectional and descriptive study was completed with 138 individuals. The study was carried out between April 15 and August 30, 2019, at the Orthopedics Clinic of a Research and Practice Hospital.
Results: 70.3% of the individuals had a vitamin D level of 20 ng/ml and less. It was determined that there was no significant correlation between individuals' vitamin D levels and age, VAS, WOMAC, and SF-36 subscales (p>0.05).
Conclusion: Vitamin D deficiency (VDD) is very common in individuals with OA. It may be recommended to conduct randomized controlled studies with larger sample size.
Diagnostic accuracy of sacral rhomboid dimensions in prediction of cephalopelvic disproportion in primigravidae
Authors: Archana R. , Patra Sharda 
Published: March 2021

Background: Cephalopelvic disproportion (CPD) is associated with significant maternal and fetal morbidity and mortality in developing countries. CPD complicates 2-15% of pregnancies. This study aimed to determine the diagnostic accuracy of sacral rhomboid dimensions in the prediction of CPD in primigravidaeMethods: This prospective study was conducted on 400 primigravidae at 37-week gestation in Department of Obstetrics and Gynaecology at Lady Hardinge Medical College, New Delhi. Women with height>145 cm were subjected to measurement of transverse and vertical diagonals (TD and VD) of sacral rhomboid prior to delivery. Following delivery, the women were divided in two groups: control group (normal delivery, n=290) and study group (caesarean section for CPD, n=56). The sacral rhomboid dimensions were compared in both the groups and statistically analysed. Results: The mean maternal height in both the groups showed no significant difference (156.88±5.7 vs 155.02±4.75, p=0.011). However, in univariate analysis, maternal height of≤154.5 cm, VD ≤10.25 cm and TD≤9.75 cm showed a diagnostic accuracy of 58.3%, 55.4% and 78%, respectively. Of all the parameters, TD≤9.75 cm was the most significant factor in predicting CPD (34% vs 13%), OR 3.3 (95%CI: 1.7- 6.7, p<0.001).Conclusions: A simple measurement of transverse diameter of sacral rhomboid is a better predictor of CPD in an average height Indian primigravidae. It can be used in community hospital to detect high risk primigravidae.

Authors: Sharma Shuchi , Dogra Poojan , Sharma Reena , Bhardwaj Suraj 
Published: March 2021

Background: Caesarean section is the most commonly performed abdominal operation in women all over the world. Caesarean sections during the second stage labour accounts for approximately one fourth of all primary caesareans. Caesarean section at full cervical dilatation is technically difficult and is associated with increased trauma to the lower uterine segment and adjacent structures, as well as increased haemorrhage and infection. Aims and objectives were to determine the indications, maternal and foetal morbidity associated with caesarean section in the second stage of labour.Methods: This prospective study included consecutive 50 cases of caesarean section deliveries conducted in second stage of labor for singleton live pregnancies at term. The data collected in the study was analyzed in terms of maternal demographics, indications of caesarean section, intra-operative and postoperative complications and neonatal outcomes.Results: In our series of 50 deliveries, arrest of descent of fetal head due to malposition was the most common indication of caesarean section accounting for 74% and average procedure time was 45-70 minutes. PPH (62%) was the most common complication. Bladder injury was found in 14% cases. Neonatal outcome variables like APGAR<3 at 5 minutes, respiratory distress and neonatal death were observed in 7, 26 and 2 deliveries respectively.Conclusions: Women undergoing cesarean section in second stage of labour are associated with increased maternal and fetal morbidity. They require special care and hence operation should ideally be performed and supervised by an experienced obstetrician. A proper judgement is required to take a decision for caesarean section at full cervical dilatation.

Published: March 2021

<p class="abstract">Schwannoma is a benign slow-growing tumour that arises from Schwann cells of the peripheral nerve sheath. The head and neck are common locations of this neoplasm. Intraoral schwannoma is uncommon, with the tongue being the most common site. The tumor can remain asymptomatic for a long period of time. The patient may present with symptoms such as a lump, swallowing difficulty, pain or discomfort, voice change, paresthesia, snoring, bleeding or ulceration. The tumor is usually slow-growing, solitary and well-encapsulated and malignant transformation is very rare. Sudden enlargement of the tumor can occur even from trivial trauma. Only approximately 50% of these tumors have a close relationship with a nerve. Transoral resection is the treatment modality of choice. Histopathological examination and immunohistochemistry help in confirmation of the diagnosis. Recurrence of the tumor is very rare. This is a case report of a 26-years-old lady with schwannoma in the ventral surface of the tongue successfully treated by transoral resection with the KTP-532 Laser. </p>
AN ECOLINGUISTIC ANALYSIS OF LINGUISTIC DISCOURSES IN ADVERTISEMENTS FRAME STORIES TO ENHANCE THEIR IMPORTANCE TO REPLACE NATURAL PRODUCTS
Authors: Ain Quratul , Ahmed Fasih , Nawaz Muhammad 
Published: March 2021

Purpose of the study: The purpose of the research is to analyze the linguistic features of the advertisements, to reveal the stories, developed by manufacturers, which appear to be ecologically protective and aligned with the values of ecosophy. Further, it aims to identify the role of language in establishing ecological preferences for consumers.
Methodology: The data has been collected from the official websites of five food manufacturing companies, which is made limited to beverages and dairy products. The advertisements are analysed under the theoretical framework of Agenda Setting Theory and Framing Theory, using the model of ecolinguistic analysis by Stibbe (2015).
Main Findings: It is incurred that the food manufacturing companies develop different stories that are succinctly insinuated, where the readers consider them mundane but the stories instill certain perceptions in readers’ minds and tame the purchase choices of consumers in daily life, through the use of language.
Application of this study: The research dismantles the ecological stance of the discourses and evaluates them in the light of ecosophy, it is helpful for the general public to identify the ecologically destructive discourses and how food manufacturers can improvise their discourses to increase consumerism. The language is used in such an emollient manner that the readers assume it to be for the sake of marketing but they clad the ideology of consumerism in each story.
Novelty/Originality of this study: The study is unique in the sense that it involves the area of linguistics in combination with ecology. It unveils how linguistics discourses in advertisements frame stories to replace the use of natural products. The linguistic discourses are used as a tool for commercial purposes, however, the purpose is to commercially glorify the product as a better source of natural outcome in front of consumers.
