German Health Narratives between Life Reform and Medical Enlightenment, 1890–1930
Authors: Treitel Corinna
Published: March 2023

This article traces the emergence of the health narrative as a new genre of bodily knowledge in late nineteenth- and early twentieth-century Germany. Health narratives were life stories told by or about an individual, either real or fictional, who made conscious choices about how to conduct their bodily existence. Pioneered by lay health seekers known as life reformers, health narratives were co-opted by physicians hoping to reinvent medical enlightenment for the twentieth century. In addition to surveying the variety of forms that health narratives took in adult and children’s literature, the article explores the paradoxes and contradictions that ensued around voice, agency, embodiment, and selfhood as these narratives spread from life reform to medical contexts.

Ability of Anthropometric Measurements to Predict Metabolic Health among Patients in Alberta: A Cross-sectional Study in Primary Care
Authors: Ghosh Sunita , Purcell Sarah A. , Martin Ken , Lima Isac , Prado Carla M.
Published: March 2023

Purpose: This study compared anthropometric and body fat percent (BF%) equations in relation to measures of metabolic health.

Methods: BF% calculations (Bergman, Fels, and Woolcott) and anthropometric measurements were used to determine obesity among a sample of patients attending primary care in Alberta, Canada. Anthropometric variables included body mass index (BMI), waist circumference, waist:hip ratio, waist:height ratio, and calculated BF%. Metabolic Z-score was computed as the average of the individual Z-scores of triglycerides, total cholesterol, and fasting glucose and the number of standard deviations from the sample mean.

Results: Five hundred and fourteen individuals were included (41.2% male, age: 53 ± 16y, BMI: 27.4 ± 5.7 kg/m2). BMI ≥ 30 kg/m2 detected the smallest number of participants (n = 137) as having obesity, while Woolcott BF% equation categorized the largest number of participants as having obesity (n = 369). No anthropometric or BF% calculation predicted metabolic Z-score in males (all p ≥ 0.05). In females, age-adjusted waist:height ratio had the highest prediction power (R2 = 0.204, p < 0.001), followed by age-adjusted waist circumference (R2 = 0.200, p < 0.001) and age-adjusted BMI (R2 = 0.178, p < 0.001).

Conclusions: This study did not find evidence that BF% equations more strongly predicted metabolic Z-scores than other anthropometric values. In fact, all anthropometric and BF% variables were weakly related to metabolic health parameters, with apparent sex differences.

Authors: Moges Wudneh Ketema , Endalamaw Tena Manaye
Published: March 2023

Objective: Diabetes mellitus is a metabolic disorder that develops over time and affects the cardiovascular system, eyes, kidneys, nerves, and blood sugar levels. The aim of this investigation was to determine the prevalence of diabetic mellitus patients, identify the associating risk factors using a multilevel longitudinal model, and understand the multilevel model changes for the level-1 and level-2 models.  Material and Methods: We examined such types of scenarios using multilevel longitudinal models such as the simple random intercept multilevel model, the random coefficient model, and the null model.  Results: There were 248 individuals with diabetes mellitus enrolled in the study for follow-up measurements over 4 time points, among these 248 individuals, 211 had complete data for all four time points. Based on the intraclass correlation coefficient, much of the variability (88.35%) in diabetes mellitus patients was accounted for by the follow-up time in this study, whereas 11.65% of the variability could not be accounted for by the follow-up time. Moreover, the data analysis suggested that sex had a significant effect on diabetes mellitus patients with the progression of time.  Conclusion: Based on the results of our study, sex, baseline fasting and educational status had a significant effect on diabetes mellitus patients over time. The educational status of diabetes mellitus patients was found to have a significant effect throughout the follow-up time; this shows that when treating diabetes mellitus patients, the physician should beware of the nature of the disease and how to management diabetes requires a high level of awareness and motivation on part of the patients regarding self-care.
Random Forest Importance-Based Feature Ranking and Subset Selection for Slope Stability Assessment using the Ranger Implementation
Authors: DEMİR Selçuk , SAHİN Emrehan Kutlug
Published: March 2023

Stability problems of slopes can arise from various factors such as geometrical, geological, seismic etc. For many years, conventional methods such as limit equilibrium method, numerical methods, and statistical methods have been successfully utilized to predict the stability of slopes. On the other hand, several machine learning (ML) attempts have been made for predicting slope stability using datasets available in the literature. The present study aims to build classification models for the assessment of the stability of slopes using the Ranger algorithm. A total of 168 cases with six input parameters (slope height, unit weight, slope angle, cohesion, pore water pressure ratio, and internal friction angle) are used to generate models. In the first step, random forest (RF) feature importance scores of the six features are determined and five different prediction models were produced by reducing the feature numbers of the dataset. The developed models are then assessed using performance metrics and results are compared to choose the best prediction model. According to the obtained results, the feature importance-based feature ranking and subset selection approach (i.e., RF feature importance) affect the performance of the models. It is observed that from the RF feature importance scores, the unit weight is found to be the most influencing feature that affects the stability of slopes for the studied dataset. In addition, the Ranger model developed with five features (Model IV) achieves the highest test accuracy with a value of 90%.

To be a ‘Biainian’: some textual and archaeological manifestations
Authors: Grekyan Yervand
Published: March 2023

Some Urartian royal inscriptions dated to the 7th century BC several times mention a group of people, calling them ‘Biainians’. The context, in which the ‘Biainians’ are figuring along with ‘foreigners’, is negative, as they appear only in the curse formulae of those inscriptions. Actually, they were considered as potential threat towards the royal power. The article discusses the role and social status of those ‘Biainians’ and the manifestations of that status in written sources and in archaeological context.

Published: March 2023

The article is dedicated to the study of tomb materials accidentally discovered during excavations in the Shirak region in recent years. The first is the tomb excavated in the area of Azatan village, which is comparable in structure and materials to the complexes of the first stage of the Early Bronze Age, such as the tombs of Talin and Jrvezh, which date back to the third quarter of the 4th millennium BC. The other partially destroyed tomb is located in Ashotsk, the materials of which belong to the Early Kurgan and Trialeti (Tṙełk‘)-Vanadzor cultures. The materials of Azatan tomb are widening our knowledge of the poorly studied Trialeti-Vanadzor culture in Shirak. Of similar significance is the tomb of Aregnadem belonging to the terminal stage of the Trialeti-Vanadzor culture. Thus, the materials of the above-mentioned tombs complement the source basis for the study of different stages of the Early to Middle Bronze Age in Shirak.

Study of the Classical sites of Armenia during the years of the Third Republic (1991-2018)
Authors: Zardaryan Mkrtich H.
Published: March 2023

The end of the 20th century in Armenia was marked by several events which had a turning influence on the political status of the country, on its state system, and on the way of life of the population. These radical changes naturally affected scientific life, including the process of archaeological research. Under new, quite difficult conditions, the number of sites studied and the scale of research was considerably limited, and the continuation of existing works disturbed. Nevertheless, under the new political and economic situation the opportunities for international research projects increased for Armenian archaeologists. This political and social-economic transformation was naturally reflected in the archaeological studies of the Classical period in Armenia too; compared with the 1980s, the last decade of the 20th century saw a reduction in the number of sites researched and the ongoing excavations scaled back. During that time span only limited works were carried out in the areas of the capitals of Armavir and Artashat (see below).

New firm formation and regional employment in Russia: Direct and indirect effects
Authors: Salimova D. R. , Tsareva Yu. V. , Zemtsov S. P.
Published: March 2023

Studies of employment growth factors are more relevant during crises. Review of foreign studies and analysis of Russian data in 2005—2018 using a distributed lag model based on the Almon method shows that there are multidirectional short-term direct and longer-term indirect effects of starting a business on employment growth. The regional context is important; and the prevalence of one effect over another and the direction of influence of additional factors depend on the type of region. Thus; for large agglomerations with high labor productivity and an active SME sector; an S-shaped lag structure of the dependence of employment on the creation of new firms was revealed: with short-term positive; medium-term negative; and further positive effects. For regions with low urbanization; labor productivity and a less active SME sector; the most striking is the short-term positive impact on employment from the opening of firms; which is replaced by a negative one after 2—3 years. At the same time; in the latter regions; the total impact may be higher than in the former; and on average; a new firm (per 1;000 people in the workforce) leads to an increase in employment by 0.56 p.p. This provides grounds for some policy recommendations.
The monetization of economy: An indicator that indicates nothing
Authors: Goryunov E. L.
Published: March 2023

The indicator of monetization of the economy; equal to the ratio of nominal money supply to nominal GDP; is very popular among Russian economists and is used to assess the effectiveness of the monetary policy pursued and is often employed in cross-country comparisons. Many economists believe that the monetization of the Russian economy is excessively low; which reflects the underdevelopment of the national financial system and requires steps towards monetary expansion. According to this view insufficient monetization of the Russian economy is as an obstacle to its rapid development; therefore increase in monetization should be made a key priority of the Bank of Russia’s policy. Although widely accepted; the complex of theories; ideas and assumptions behind these recommendations; however; has never been adequately empirically tested. In this paper we formulate several statements that are shared by the majority of economists in this area; based on a review of relevant publications; and then test the statements on cross-country data. As a result of empirical testing; it was shown that most of the statements are not supported by evidence. The monetization indicator does not carry any additional relevant information about the macroeconomics conditions; having other indicators considered. High monetization does not create additional stimulus for economic growth; and the ability of central banks to affect monetization is limited significantly. In countries with low monetization; inflationary risks of monetary expansion are sharply higher. The conducted empirical study provides arguments against the broad use of the monetization indicator in macroeconomic analysis and casts doubt on the idea of laying responsibility for increasing the level of Russian economy monetization on the Bank of Russia.
Is it worth limiting the ownership and investment of foreign companies? (Stock market case)
Authors: Nepp A. N.
Published: March 2023

To identify possible equity market implications of restrictions on foreign ownership and investment in Russia; as well as against Russian ownership abroad; we reviewed data from 38 countries and applied fixed effects models to panel data. We show that restrictive measures against foreign ownership and investment will have a negative impact on the capitalization of the domestic stock market. The effect will be amplified under the influence of such factors as corruption; freedom of investment; financial; trade and business freedoms. The quality of the judiciary is most important when examining the share of the domestic stock market in the world stock market. Tax incentives and increased fiscal freedom will not be able to have a positive impact in the face of restrictive measures against foreign ownership and investment.
Efficiency of large cities: Theory and empirics
Authors: Melnikova L. V.
Published: March 2023

The paper assesses the advantages of large cities as places of concentration of economic activity in terms of production efficiency. For this purpose; we made quantitative estimates of the relationship between the size of cities and indicators of productivity. The theory justifies the presence of such relationships by various agglomeration effects; estimates of which have been reduced over the last 20 years as the number of empirical studies has been growing. The calculations are based on Russian municipal statistics; taking into account its limitations. The study has demonstrated that the direction of the relationship between city size and productivity depends on the characteristics of the industry structure of the city economy; which; in turn; depends on the city’s place in the urban hierarchy. A negative relationship is characteristic of highly specialized cities; while a positive one emerges as industry localization declines and diversification of the city economy increases.

ABSTRAKEfisiensi pemasaran kayu gergajian sengon berpengaruh besar terhadap keberlanjutan industri penggergajian kayu rakyat. Tujuan dari penelitian ini adalah menganalisis efisiensi pemasaran kayu gergajian sengon pada industri penggergajian kayu rakyat. Penelitian dilakukan dengan wawancara mendalam dan observasi langsung.  Pengambilan sampel dilakukan secara sengaja (purposive sampling) terhadap 5 Industri penggergajian kayu yang memproduksi kayu gergajian sengon secara berkelanjutan. Hasil penelitian menunjukan bahwa pemasaran produk papan, balok, kasau dan reng memiliki kecenderungan yang sama terhadap indikator efisiensi pemasaran.  Berdasarkan indikator producer’s share dan perhitungan efisiensi pemasaran, pemasaran ke empat produk berjalan efisien akan tetapi berdasarkan indikator margin pemasaran, margin keuntungan dan rasio profit margin, pemasaran berjalan dengan tidak efisien. Hal ini dilihat dari margin pemasaran, margin keuntungan dan rasio profit margin yang tidak merata pada semua produk dan semua saluran. Hasil penelitian ini belum dapat menggambarkan efisiensi pemasaran secara keseluruhan sehingga indikator efisiensi pemasaran lainnya perlu juga dipertimbangkan seperti aspek fungsi-fungsi pemasaran, volume penjualan dan kepuasan konsumen.Kata kunci: efisiensi pemasaran, industri penggergajian, kayu gergajian sengonABSTRACTThe marketing efficiency of sengon sawn wood has a big impact on the sustainability of sawmill industry. The purpose of this research is to analyze the efficiency of marketing of sengon sawn wood in the sawmill. The research was conducted by in-depth interviews and direct observation. Sampling was carried out purposively of 5 sawmills that produce sawn wood in a sustainable manner. The results showed that the marketing of boards, beams, rafters and battens had the same tendency towards marketing efficiency indicators. Based on the producer's share indicator and the calculation of marketing efficiency, the marketing of the four products is running efficiently but based on indicators of marketing margin, profit margin and profit margin ratio, marketing is running inefficiently. This can be seen from the uneven marketing margins, profit margins and profit margin ratios for all products and all channels. The results of this study have not been able to describe the overall marketing efficiency so that other indicators of marketing efficiency also need to be considered such as aspects of marketing functions, sales volume and customer satisfaction. Keywords: marketing efficiency, sawmill industry, sengon sawn wood

Published: March 2023

This article aims to provide a summary of local governments' strategies as well as long- and short-term perspectives on the effects of East Java Province's population growth rate and Human Development Index on unemployment. This article's technique involves analyzing the impact of the dependent variable on the independent variable using parametric quantitative methodologies. In order to see both the short- and long-term consequences, an analysis of the Vector Error Correction Model is employed as the analytical model. The findings indicate that the Human Development Index and population growth rate have a short-term negative impact on unemployment in the province of East Java. In contrast, population growth in East Java Province has a beneficial effect on the rise in unemployment when considered over the long term. The Millennial Job Center and other programs are a long-term answer to the problem of unemployment in the province of East Java
ЗАРУБІЖНИЙ ДОСВІД СИСТЕМИ ПУБЛІЧНОГО УПРАВЛІННЯ СФЕРОЮ ФІЗИЧНОЇ КУЛЬТУРИ ТА СПОРТУ
Authors: ЩОКІН Ростислав , БЕЛЕНЮК Жан
Published: March 2023

В статті з метою пошуку оптимальних моделей та інструментів, здатних сприяти удосконаленню вітчизняної системи публічного управління у сфері фізичної культури та спорту розглянуто досвід зарубіжних країн. В статті виділено три основні моделі управління: американську, європейську та азійську, охарактеризовано властиву їм національну систему функціонування спорту та систему їх публічного управління. Розглянуті у статті системи публічного управління зарубіжних країн проаналізовано за критеріями: рівня участі держави у регулюванні системи спорту; типу та форми організаційної моделі та управлінських структур, які координують сферу фізичної культури та спорту; місія, цілі та принципи системи публічного управління у сфері фізичної культури та спорту; особливості нормативно-правового регулювання та ресурсного забезпечення сфери фізичної культури та спорту. Виокремлено та охарактеризовано американську та європейську систему публічного управління у сфері фізичної культури та спорту. В Європейській системі публічного управління виокремлено країни, в яких державне управління спортом здійснюється на федеральному рівні самостійним спеціалізованим органом (Франція, Великобританія, Люксембург, Норвегія, Португалія, Угорщина); країни, які не мають самостійного спеціалізованого органу державного управління, а управління здійснюється громадськими організаціями, об’єднанням федерацій, асоціацій та спілок спорту (Німеччина, Данія, Норвегія, Австрія). Зроблено висновок в потребі подальшої децентралізації та удосконалення взаємовідносин між окремими структурами вітчизняної сфери публічного управління у сфері спорту та фізичної культури; діджиталізації публічного управління сферою фізичної культури та спорту; інтенсифікації розробок та реалізації національних програм, державних стандартів з фізичної підготовленості населення, проведення моніторингу за фізичним станом та здоров’ям усіх вікових груп.
РОЗВИТОК ОХОРОНИ ЗДОРОВ’Я В УКРАЇНІ В КОНТЕКСТІ МІЖНАРОДНИХ ЗОБОВ’ЯЗАНЬ ТА НАЛЕЖНОГО ЗАБЕЗПЕЧЕННЯ НАЦІОНАЛЬНИХ ІНТЕРЕСІВ

У статті досліджено розвиток системи охорона здоров’я в Україні в контексті виконання міжнародних зобов’язань та належного забезпечення національних інтересів на основні міжнародно-правових актів в галузі охорони здоров’я, обов’язковість на виконання яких взяла на себе Україна як суб’єкт міжнародного права. За результатами проведеного дослідження встановлено, шо для розвитку охорони здоров’я в Україні в контексті міжнародних зобов’язань та належного забезпечення національних інтересів у публічному управліннізаконодавством України передбачено сумлінне дотримання міжнародних договорів за принципом міжнародного права з метою належного забезпечення національних інтересів, здійснення цілей, завдань і принципів зовнішньої політики України, закріплених у Конституції України та законодавстві України. Так право людини на охорону здоров’я закріплено у положеннях міжнародних правових актах, які ратифіковано Україною, а саме: Конвенція про захист прав людини і основоположних свобод (ратифіковано Законом України № 475/97-ВР від 17.07.97); Міжнародний пакт про економічні, соціальні і культурні права (ратифіковано Указом Президії Верховної Ради Української РСР N 2148-VIII (2148-08 ) від 19.10.73); Конвенція про права осіб з інвалідністю (ратифіковано Законом України № 1767-VI від 16.12.2009); Конвенція про права дитини (ратифіковано Постановою Верховної Ради України ВРУ № 789-XII від 27.02.91); Європейська соціальна Хартія (ратифіковано із заявами Законом України № 137-V від 14.09.2006, ВВР, 2006, N 43, ст.418); Конвенція Ради Європи про підроблення медичної продукції та подібні злочини, що загрожують охороні здоров’я (ратифіковано Законом України № 4908-VI від 07.06.2012) та інші, у тому числі угоди про надання медичної допомоги, співробітництво в галузі охорони здоров’я і медичних наук тощо. Водночас, на національному рівні (з урахуванням міжнародного контенту) формується власний правовий механізм забезпечення функціонування системи охорони здоров’я, який є основою формування національної політики охорони здоров’я, і функціонування системи в цілому.
