Risk compensation after COVID-19 vaccination: Evidence from vaccine rollout by exact birth date in South Korea.

We utilize the phased rollout of COVID-19 vaccines by exact birth date in South Korea as a natural experiment for testing risk compensation. People may resume face-to-face social activities following vaccination because they perceive lower risk of infection. Applying a regression discontinuity design based on birth date cutoffs for vaccine eligibility, we find no evidence of risk-compensating behaviors, as measured by large, high-frequency data from credit card and airline companies as well as survey data. We find some evidence of self-selection into vaccine take-up based on perception toward vaccine effectiveness and side effects, but the treatment effects do not differ between compliers and never-takers.

«Нелегкая вечность своя»: Дополнения к биографии Владимира Щировского

The article reconstructs details of the biography of the poet Vladimir Yevgenievich Schirovsky (1909‒1941) based on archival sources. Until today, only the memoirs of his sister-in-law, Aleksandra Dorrer, served as the source of his life’s details. The facts presented in her memoirs had undergone only partial documentary verification. The article establishes Vladimir Schirovsky’s exact date of birth, clarifies the dates and the crucial milestones in the lives of his father, Yevgeny Schirovsky (1850‒1918), and his maternal grandfather Erast Yezhov (1842 – after 1887) using historical records from the Moscow University archives and identifies Schirovsky’s family ties with the noble families of the Yezhovs, Savitskys, Vasilkovskys, and Akaro. Yevgeny Schirovsky, assigned to the lower class of the meschane (urban petit bourgeois) as an illegitimate child of a noble, built an exceptional career as a civil servant. At the peak of his career between 1897 and 1906, he successively held a provincial governorship of the Łomża Governorate, the Kielce Governorate, and the Radom Governorate of the Congress Poland, having risen to the rank of the Privy Councilor (but not to the rank of a senator, as incorrectly thought before based on Aleksandra Dorrer’s account). Yevgeny Schirovsky’s father, Aleksey Kozmich Schirovsky (1805 – after 1869), and grandfather Kozma Alekseyevich Schirovsky (1771‒1849), both physicians who worked at the Mariinsky Hospital for the poor in Moscow alongside Mikhail Andreyevich Dostoevsky, the father of Fyodor Dostoevsky, belonged to the closest circle of friends of the Dostoyevsky family.

Herpes zoster vaccination prevents or delays dementia: causal evidence from a country‐wide natural experiment in Wales

AbstractBackgroundThere is growing recognition that infectious agents, particularly herpesviruses, could play a role in the development of some types of dementia.MethodIn Wales, eligibility for the herpes zoster vaccine (Zostavax) for shingles prevention was determined based on an individual’s exact date of birth. Those born before September‐2‐1933 were ineligible (and remained ineligible for life), while those born on or after September‐2‐1933 were eligible. This natural experiment provides causal, as opposed to correlational, evidence because there is no plausible reason why adults born just one week apart should differ systematically from each other. We used a regression discontinuity design in Welsh country‐wide data on primary and secondary care encounters, and death certificates. The outcome was a new dementia diagnosis as recorded in any of these data sources.ResultWe included 282,541 individuals born between September‐1‐1925 and August‐31‐1941. The percentage who received the zoster vaccine increased from 0.01% among those one week too old to be eligible, to 47.2% among those one week younger. Receiving the vaccine reduced the probability of a new dementia diagnosis over a follow‐up period of seven years by 3.5 percentage points (95% CI: 0.6‐7.1, p = 0.019), corresponding to a 22.4% relative decrease. There were significant protective effects from the vaccine for Alzheimer’s disease but not vascular dementia. Effects were far stronger among women than men. To demonstrate that our approach is causal, we show that i) there were no differences in pre‐existing conditions or uptake of other preventive interventions across the date‐of‐birth eligibility cutoff; ii) the zoster vaccine had no effects on any other common causes of morbidity and mortality; and iii) no other interventions used the same date‐of‐birth eligibility cutoff.ConclusionIn addition to identifying a readily available preventive intervention for dementia, our findings strongly suggest an important role of the varicella zoster virus in the etiology of dementia, particularly among women. Unlike existing studies in this field, this analysis provides causal evidence because individuals who differ in age by just one week are exchangeable with each other on both observed and unobserved characteristics, except for a large difference in the probability of receiving the zoster vaccine.

DOUBLE MYSTIFICATION OF THE DRAHOMANOV SISTERS

The subject of this research is the family correspondence of the Drahomanovs, a significant part of which remains unpublished. These archival materials have been prepared for publication in the upcoming issue of the annual journal “Heritage: Literary Source Studies. Textology”. They significantly enrich our knowledge of Mykhailo Drahomanov’s life and his circle, while also presenting some complex tasks for the commentator. In particular, the letters of M. Drahomanov’s youngest brother, Oleksandr, mention his daughters Oksana and Nina. The dates mentioned in these references contradict the commonly known information about their birth years. Therefore, there is a need to clarify their actual years of birth.
 Oksana Drahomanova was a lawyer, a participant in Ukraine’s liberation struggle in 1918—1921, an international women’s movement activist, a writer, and a translator. Various mentions provide different birth dates for Oksana, most often 1894 but occasionally 1892. The information about Oksana and Nina Drahomanova that has been circulated in the scholarly literature is based mostly on the distant relatives’ and acquaintances’ memories, which are often unreliable in terms of dating. In addition, Oksana herself may have altered her passport data, ‘rejuvenating’ herself by at least three years during her emigration overseas. The present research incorporates modern sources and archival materials, including memories, photographs, correspondence, and other documents. A decisive piece of evidence was a photograph of little Oksana, about one and a half years old, with a gift inscription from her father, dated June 1892. Thus, it is proved that Oksana Drahomanova was actually born in early 1891, but the exact date has yet to be established.
 Little is known about Nina Drahomanova, with her birth year commonly believed to be 1900 or 1901. However, based on the letters of her father Oleksandr from 1898—1912, it can confidently be stated that Nina was born in 1898.
 In addition, through the study of sources, the exact birth date of Oleksandr Drahomanov is determined to be August 4, 1859, according to the old style.
 The paper demonstrates how preparing texts for publication and scholarly commentary on archival materials (in this case, epistolary ones) lead to heuristic discoveries.

The short-term effects of fixed copayment policy on elderly health spending and service utilization: evidence from South Korea's age-based policy using exact date of birth.

A large number of the poor elderly in Korea have been exposed to the risk of insufficient proper medical treatments because of financial restrictions. South Korea launched policies to reduce the cost-sharing burden on the elderly, including one compelling the elderly to pay a fixed out-of-pocket amount for outpatient treatments. The impacts of such policies, however, have yet to be elucidated. In this paper, we estimate the short-term effects of the fixed outpatient copayment policy on the health-related behavior of the elderly. We employed a regression discontinuity design by using the exact days before and after the sample's 65th birthdate as the assignment variable, along with the restricted individual-level 2012 and 2013 National Health Insurance claims data. Results show that the policy increased the elderly's health service utilization numbers and reduced out-of-pocket spending for insured services. Moreover, the effects on prescription spending and the insurer's burden differed depending on beneficiaries' characteristics.

Abstract P472: Matching Young Adult Strokes in a Claims Database to the Clinical Get With the Guidelines-Stroke Registry

Background: Due to its lower incidence, strokes in young adults, studies have difficulty answering why there are more women than men less than 35 with incident strokes. The goal of this study is to link claims and registry data to create a new longitudinal and clinical cohort of strokes in young adults. Methods: Colorado mandates reporting of commercial and public insurance (Medicaid and Medicare) claims to the All Payer Claims Database (APCD). We identified all first-time stroke admissions using ICD-9 /10 codes between 2012 to 2018 in young adults (18-55). Get with the Guidelines (GWTG) Stroke registry has stroke cases from 41 hospitals in Colorado since 2010. Matching was based on exact birthdate, sex and +/- 1day in admission/discharge dates. Confirmation of match was based on comparing the admitting hospital between the two databases. Cardiovascular(CV) and non-CV risk factors occurring from enrollment until 1 day prior to stroke date in the APCD were included. Student’s T-test, and Z-tests were used to test differences between men and women. Results: We identified 3032 stroke cases in the APCD. Of these, 1455 (48.0%) matched to an admission in the GWTG-Stroke registry. Of these, 1303 (89.6%) also matched based on the admitting hospital (Table). The final cohort contained 51% women, 11.3% <35, 35.2% between 35-45, and 63.5% between 45-55. The most common CV risk factors were hypertension, hyperlipidemia, and tobacco use in men, and hypertension, tobacco use, and obesity in women. The most common non-CV risk factors were migraines, renal failure, thrombophilia in men and migraines, malignancy, and thrombophilia in women. The prevalence of cardiovascular risk factors was higher in men, while the prevalence of non-cardiovascular risk factors was higher in women. There was no difference in the severity of strokes between men and women. Conclusions: Clinical registries such as GWTG-Stroke can be used to supplement longitudinal administrative cohorts of young adults with stroke to get richer data on stroke etiology and severity.

The Central Scientific Library plans to create electronic memorial libraries dedicated to outstanding Siberian scientists.The article presents the results of biobibliographic studies, which made it possible to identify new materials about one of the initiators of the creation of the Branch of the USSR Academy of Sciences in Irkutsk, Taras Timofeevich Deulya (1901–1974), Candidate of Geological and Mineralogical Sciences, Associate Professor of Irkutsk State University (ISU), scientist, teacher and public activist. In particular, the exact date of birth was established, the list of his unpublished works was discovered. Based on the collected material, the website will be created dedicated to the life and work of T. T. Deulya.

Once Again on Boris Godunov’s Birthday. Heinrich von Logau’s Account

European diplomatic sources from the early 17th century provide us with previously unaccounted for data on Russian history. Thanks to a report by Georg Tectander, a member of Emperor Rudolph II’s mission to Russia, we can now establish the exact date of birth for Boris Godunov. An unpublished manuscript by Tectander’s contemporary and compatriot, Baron Heinrich von Logau, who visited the Tsardom of Russia at the same time, allows us to verify this date as well as to broaden our perspective on everyday life and ceremonial of the royal court, on the Tsar’s personal piety and on the status of the ancient tradition of celebrating birthdays and name days. Moreover, analyzing various calendars used by the diplomats of that era allows us to ascertain that one’s preference for the Gregorian or Julian calendar was not defined by national strategies only but remained a matter of personal choice that was subject to change during one’s life.

FOR THE 100th ANNIVERSARY OF PROFESSOR E. E. TARMAKHANOV (DETAILS OF THE SCIENTIST'S BIOGRAPHY)

The article discusses the issues concerning the date and place of birth of Doctor of Historical Sciences, Professor E. E. Tarmakhanov. Based on historical sources, we have identified his exact date of birth. Relying on information from autobiographical materials, memoirs of relatives and colleagues of the scientist, official documents published on the Internet, monographic studies, research papers of Professor E. E. Tarmakhanov, we have formulated and reasonably substantiated the thesis about the exact place of birth of the sci-entist in accordance with the territorial division that existed at that time. The article is based on the following historical sources: archival documents from the fund of the Lenin-grad State University, the works by E. E. Tarmakhanov dedicated to the history of Burya-tia, Ust-Orda Buryat Autonomous Okrug, and his small small motherland — Irkhidey, as well as information from the official websites of Administration of the Municipality of Irchidey and the Municipal Budgetary Educational Institution “Baldunnikov Irkhidey Secondary School”. Our conclusions are important from the perspective of the individual peculiarities of the personality of Professor E. E. Tarmakhanov, his worldview and values, which determined the significant contribution of the scientist to the development of histor-ical studies in Buryatia.

ДАТА РОЖДЕНИЯ К. Д. УШИНСКОГО: ЗАВЕРШЕНИЕ ДИСКУССИИ

The problem associated with determining the exact date of birth of great Russian teacher Konstantin Dmitrievich Ushinsky is being considered. There is a contradiction in the available documentary sources, which became the basis for the appearance of different versions, there are two main ones for 2021 — February 19, 1823 and February 19, 1824. It is noted that the basis of the version of 1824 was the memoirs of Ushinsky himself, his close friends M. K. Chaly and Yu. S. Rekhnevsky, as well as his first biographers. The unreliability of memories as a historical source is emphasized, in support of the memoirs of Chaly, from which one can conclude both about 1823 and about 1824. The reasoning of the Soviet adherents of version 1824 is considered, based on the authors' assumptions about deception by the parents of K. D. Ushinsky of the Tula Spiritual Consistory to obtain a birth certificate, making son Konstantin a year elder than the true age, with the aim of earlier enrollment in the gymnasium. Documents of the State Archive of the Tula Region related to the issue of identifying the Tula Spiritual Consistory of witness and documentary evidence of the birth and baptising Konstantin on February 19, 1823 in Tula are analyzed. It is emphasized that the testimony of witnesses is supported by irrefutable documentary evidence — a formal list for the service of Father D. G. Ushinsky, issued by the office of the Minister of Finance of the Russian Empire. The role of ascetics — teachers of Yaroslavl State Pedagogical University named after K. D. Ushinsky and Tula State Pedagogical University named after L. N. Tolstoy in substantiating and promoting the version of 1823 is considered. The decisive role of the President of the Russian Federation V. V. Putin in the final recognition of 1823 the year of K. D. Ushinsky birth is emphasized.

IN VITRO FERTILIZATION (IVF) OUTCOMES AND PREDICTING FACTORS IN A RESOURCE-LIMITED SETTING

Abstract Introduction Ethiopia has only one public In-vitro fertilization (IVF) center which was opened one year back. The aim of the study is therefore to determine predictors of the outcome of IVF in the only and newly opened public fertility center in Addis Ababa, Ethiopia. Methods The study is conducted in the public IVF center in Ethiopia between; April 01, 2019, to March 30, 2020. A retrospective cross-sectional study design was employed. All IVF clients meeting the inclusion criteria were included in the analysis. Result There was a total of 199 couples included in the study. The clinical pregnancy rate was found to be 30.1%. The odds of getting pregnant is 61% less among participants with female partners age ?35 years, AOR 0.39, CI 0.18-0.83 with a p-value of 0.015. Good responders ((?4 oocytes retrieved) accounts for 152(76.4%) of the cases. Age of female partner, day 3 Follicle Stimulating Hormone (FSH), and Antral Follicle Count (AFC) count ?5 were significantly associated with good ovarian stimulation response with a p-value of 0.050,0.002 and 0.005 respectively. Conclusion Even though near two-third of the study participants did not know their exact date of birth, the reported age of female partner <35 years is associated with both good ovarian response and occurrence of pregnancy emphasizing its importance for clinical decision making. Day 3 FSH and AFC ?5 were associated with good ovarian stimulation response. Therefore, we recommend the combination of female partner age, day 3 FSH, and AFC ?5 to predict ovarian response in low resource settings, since variables can be readily available without much cost to patients. Furthermore, we would like to recommend follow up studies with better sample size and prospective cohort design to appropriately compare the different predictors of ovarian response in our setting to develop evidence-based set up specific IVF protocols and guidelines Keywords: Pregnancy rate, IVF, Resource limited setting, Predictors, Infertility, Ethiopia

A RADIOLOGICAL STUDY OF APPEARANCE OF OSSIFICATION CENTRES IN THE CARPAL BONES IN BOYS AND GIRLS (AGE GROUP 2 to 12 YEARS) OF THE JODHPUR REGION

Background: To study the appearance of ossification centres of carpal bones in both sexes in age group 2 to 12 years. Methods: This study was conducted to find out age from ossification of carpal bones on 200 children (2 years to 12 years of age) at Dr. S.N. Medical College and Associated Group of Hospitals, Jodhpur. Minimum age of the child was 2 years and maximum 12 years. The cases were randomly selected, but priority was given to only those children whose parents could give the exact date of birth of their children. Results: Triquetral and lunate carpals appear after capitate and hamate. Triquetral appeared at the age of 3-4 years and lunate at the age of 4-5 years. So below the age of 3 years a child may have 2 carpals which may increase to 3 at the age of 3 years and 4 at the age of 4 years in both sexes. Trapezium, trapezoid and scaphoid carpals appeared between the age of 5 to 9 years. Their appearance was slightly earlier in females than in males. These three carpals may appear simultaneously or at different times. The pisiform was last to ossify in both the sexes. In the female it appeared between 10 to 11 years of age. In male it appeared between 11 to 12 year of age. Conclusion: The sequence of appearance of carpal bones in the Jodhpur population is similar to what is described in the literature. Keywords: Carpal bone, Age, Sex

GENERATION Z IN HIGHER EDUCATION – INVESTIGATING THE PREFERRED MEDIUM OF TEXT IN ACADEMIC READING

According to Nugin et al. (2016) it is not always easy to determine the exact date of birth of every generation as the transitions have been found to be difficult to pinpoint. (9). According to Seemiller and Grace (2015), the representatives of generation Z were born between 1995 to 2010 and have already entered higher education. Reading online has become one of the most widely used sources of knowledge for learners, especially in the academic contexts (Zarrabi, 2015), thus it is not surprising that for generation Z visual media may as well have the most substantial impact whereas internet and smart devices are the main means of communication making it possible for every question to be answered immediately. Teachers nowadays are faced with a somewhat challenging task to meet the information obtaining needs and preferences of the new generation while belonging to the previous generation themselves. In order to cast light into the process of choosing the most suitable methods and materials as well as the devices for the learners of Generation Z, a research was started in Tallinn Health Care College, with an aim to investigate different generations´ text searching and reading strategies. Current article focuses on describing the preferred medium of text among the representatives of Generation Z. An online semi-structured questionnaire was conducted descriptive analysis conducted. The results direct authors toward further research to investigate the strategies of working with texts keeping in mind the characteristics of Generation Z in order to use the mediums and strategies to create effective learning possibilities in higher education.

Comparison of anthropometric data quality in children aged 6-23 and 24-59 months: lessons from population-representative surveys from humanitarian settings

BackgroundEnsuring the quality of anthropometry data is paramount for getting accurate estimates of malnutrition prevalence among children aged 6–59 months in humanitarian and refugee settings. Previous reports based on data from Demographic and Health Surveys suggested systematic differences in anthropometric data quality between the younger and older groups of preschool children.MethodsWe analyzed 712 anthropometric population-representative field surveys from humanitarian and refugee settings conducted during 2011–2018. We examined and compared the quality of five anthropometric indicators in children aged 6–23 months and children aged 24–59 months: weight for height, weight for age, height for age, body mass index for age and mid-upper arm circumference (MUAC) for age. Using the z-score distribution of each indicator, we calculated the following parameters: standard deviation (SD), percentage of outliers, and measures of distribution normality. We also examined and compared the quality of height, weight, MUAC and age measurements using missing data and rounding criteria.ResultsBoth SD and percentage of flags were significantly smaller on average in older than in younger age group for all five anthropometric indicators. Differences in SD between age groups did not change meaningfully depending on overall survey quality or on the quality of age ascertainment. Over 50% of surveys overall did not deviate significantly from normality. The percentage of non-normal surveys was higher in older than in the younger age groups. Digit preference score for weight, height and MUAC was slightly higher in younger age group, and for age slightly higher in the older age group. Children with reported exact date of birth (DOB) had much lower digit preference for age than those without exact DOB. SD, percentage flags and digit preference scores were positively correlated between the two age groups at the survey level, such as those surveys showing higher anthropometry data quality in younger age group also tended to show higher quality in older age group.ConclusionsThere should be an emphasis on increased rigor of training survey measurers in taking anthropometric measurements in the youngest children. Standardization test, a mandatory component of the pre-survey measurer training and evaluation, of 10 children should include at least 4–5 children below 2 years of age.

Catching up or crowding out? The crowd-out effects of catch-up retirement contributions on non-retirement saving

Using tax data, this paper exploits a discontinuous increase in retirement contribution limits based on exact date of birth. This paper finds clear evidence that constrained individuals increase their retirement saving when so eligible, but finds no evidence suggesting that non-retirement saving falls. In the baseline specifications, one can rule out crowd-out greater than approximately 0.38 to 0.57 at the 95% confidence level depending on the measure used. This suggests that the additional contributions induced by catch-up eligibility represent an increase in total private saving.
