Managing Market Thickness in Online Business-to-Business Markets
Authors: Bimpikis Kostas , Elmaghraby Wedad J. , Moon Ken , Zhang Wenchang
Published: June 2020

We explore marketplace design in the context of a business-to-business platform specializing in liquidation auctions. Even when the platform’s aggregate levels of supply and demand remain fixed, we establish that the platform’s ability to use its design levers to manage the availability of supply over time yields significant value. We study two such levers, each using the platform’s availability of supply as a means to incentivize participation from buyers who decide strategically when/how often to participate. First, the platform’s listing policy sets the ending times of incoming auctions (hence, the frequency of market clearing). Exploiting a natural experiment, we illustrate that consolidating auctions’ ending times to certain weekdays increases the platform’s revenues by 7.3% mainly by inducing a higher level of bidder participation. The second lever is a recommendation system that can be used to reveal information about real-time market thickness to potential bidders. The optimization of these levers highlights a novel trade-off. Namely, when the platform consolidates auctions’ ending times, more bidders may participate in the marketplace (demand-side competition); but ultimately auctions for substitutable goods cannibalize one another (supply-side competition). To optimize these design decisions, we estimate a structural model that endogenizes bidders’ dynamic behavior, that is, their decisions on whether/how often to participate in the marketplace and how much to bid. We find that appropriately designing a recommendation system yields an additional revenue increase (on top of the benefits obtained by optimizing the platform’s listing policy) by reducing supply-side cannibalization and altering the composition of participating bidders.

Envy-Free Division of Land
Authors: Segal-Halevi Erel , Nitzan Shmuel , Hassidim Avinatan , Aumann Yonatan
Published: June 2020

Classic cake-cutting algorithms enable people with different preferences to divide among them a heterogeneous resource (“cake”) such that the resulting division is fair according to each agent’s individual preferences. However, these algorithms either ignore the geometry of the resource altogether or assume it is one-dimensional. In practice, it is often required to divide multidimensional resources, such as land estates or advertisement spaces in print or electronic media. In such cases, the geometric shape of the allotted piece is of crucial importance. For example, when building houses or designing advertisements, in order to be useful, the allotments should be squares or rectangles with bounded aspect ratio. We, thus, introduce the problem of fair land division—fair division of a multidimensional resource wherein the allocated piece must have a prespecified geometric shape. We present constructive division algorithms that satisfy the two most prominent fairness criteria, namely envy-freeness and proportionality. In settings in which proportionality cannot be achieved because of the geometric constraints, our algorithms provide a partially proportional division, guaranteeing that the fraction allocated to each agent be at least a certain positive constant. We prove that, in many natural settings, the envy-freeness requirement is compatible with the best attainable partial-proportionality.

Authors: Fringer André , Stängle Sabrina , Bischofberger Iren , Büche Daniel , Praxmarer Renate , Ch. Ott Stefan , Schnepp Wilfried
Published: June 2020

Aim:

The authors aimed to evaluate the experiences of the relatives of dying people, both in regard to benefits and special needs, when supported by a mobile palliative care bridging service (MPCBS), which exists to enable dying people to stay at home and to support patients' relatives.

Design:

A cross-sectional survey.

Methods:

A standardised survey was performed, asking 106 relatives of dying people about their experiences with the MPCBS (response rate=47.3%). Descriptive statistics were analysed using SPSS 23.

Findings:

Many relatives (62.5%) reported that their dying relations when discharged from a facility to stay at home were not symptom-free. The MPCBS helped relatives maintain home care, and this was reported to be helpful. Support provided by the MPCBS made it easier for 77.6% of relatives to adjust care as soon as situations changed, and helped ensure that symptoms could be better controlled, at least for 68.2% of relatives. Younger relatives felt more encouraged by the MPCBS to care for their relatives dying at home.
When Teachers Become Students: Impacts of Neuroscience Learning on Elementary Teachers’ Mindset Beliefs, Approach to Learning, Teaching Efficacy, and Grit
Authors: Gutshall C. Anne
Published: June 2020

Previous research suggests that learning basic neuroscience constructs, especially about the malleability of the brain, impacts middle school and older students’ academic mindset, response to failure and academic persistence.  This research targets teacher beliefs using a similar model.  Teachers were taught introductory neuroscience concepts related to how the brain learns.  Session topics included: basic neurodevelopment, neuroplasticity, sleep and the brain, stress and the brain, exercise and the brain, growth mindset, growth mindset feedback, self- control and grit.   Results of this school level intervention suggest significant impacts on teachers’ mindset, teaching efficacy, teachers’ approach to learning and grit.  In particular, teacher mindset beliefs significantly increased after the teachers were taught the concepts.  Implications for schools and teacher preparation are discussed.
Away from Home Studying in Brazil: Bulgarian Children’s Experiences of Brazilian Education
Authors: Matelova Bojana
Published: June 2020

This paper presents findings from an extensive study conducted in Brazil. The main subjects of the study were Bulgarian children living and studying in Brazilian schools. The main goal was to indicate what kind of problems and obstacles they experience during the school time in Brazil and how the Brazilian government and people support these Bulgarian children. The data was collected by a Bulgarian research team that travelled to the remote regions of Brazil where many Bulgarian citizens live and work. The researchers took interviews with the Bulgarian children and their parents as well as school staff at the schools in Brazil with a high population of Bulgarian children. The analysis revealed many different problems that Bulgarian children and their parents highlighted, such as problems with the language of instructions, misunderstandings of school rules and general problems related to living in the remote areas of Brazil, such as weather and heat-related issues. Although many Bulgarian families reported some problems, they were still determined to continue their life and career in Brazil, and they want to continue to pursue their dreams.
Generalized circuit model for analysis of extraordinary transmission in multilevel slits
Authors: Kashfi Seyyed Pouriya , Kashani Zahra Ghattan
Published: June 2020

We propose a generalized circuit model for accurate analysis of the extraordinary transmission phenomenon in multilevel stepped slit structures. The multilevel stepped slit consists of some continuous sub-wavelength metal slits with different widths. By applying the proposed circuit model, we study the extraordinary transmission property of this structure for the two cases of ideal and real metal structures. The accuracy of the achieved results is validated by a full wave analysis based on the finite element method. Additionally, since the multilevel slit structure is adjustable by simply manipulating slit parameters such as widths and heights, various kinds of transmission spectra and a different number of resonance points are investigated by the circuit model and the numerical approach. Multilevel stepped slits can be used potentially as bandpass filters or optical attenuators in photonics integrated circuits.
First experience with spatial frequency domain imaging and red-light
excitation of protoporphyrin IX fluorescence during tumor
resection
Authors: Wirth Dennis J. , Sibai Mira , Wilson Brian C. , Roberts David W. , Paulsen Keith
Published: June 2020

Fluorescence-guided surgery (FGS) enhances intraoperative visualization of tumors to maximize safe resection, and quantitative fluorescence imaging (qFI) of protoporphyrin IX (PpIX) has provided additional information for guidance during intracranial tumor surgery. Previous developments in fluorescence quantification have demonstrated that the depth of fluorescence signals can be estimated given known optical properties in a lab setting, and now with the work described here that these optical properties can be determined in vivo in human brain tissue in the operating room (OR) during tumor resection procedures. More specifically, we report the first depth estimation of subsurface tumor intraoperatively, achieved with the combination of spatial frequency domain imaging (SFDI) for optical property measurement and red-light excitation of PpIX. We modified a commercial surgical microscope (Zeiss) with a digital light processing module (DLI Austin, TX) to modulate light from a xenon arc lamp to illuminate the field. White-light excitation and a liquid crystal tunable filter (LCTF Verispec) were used to measure diffuse reflectance at discrete wavelengths of 670 nm and 710 nm on a sCMOS camera. An illumination-side filter wheel allowed excitation of PpIX fluorescence at 405 nm and 635 nm, and the LCTF measured fluorescence emissions at 670 nm and 710 nm. Data acquisition and processing generated wide-field images of the depth of PpIX fluorescence within 1 minute in the OR. The ability of the clinical microscope to perform optical property mapping with SFDI and convert these wide-field estimates into images of the depth of fluorescence was tested in tissue simulating phantoms and in vivo during a craniotomy for brain tumor resection. Results indicate that wide-field optical property estimates with SFDI can be combined with depth sensing algorithms to produce maps of the depth of PpIX when exposed to red-light in the OR.
Bio-inspired flow rate sensor based on optical microfiber embedded soft film
Authors: Xu Yue , Zhang Zhang , Tang Yao , Pan Jing , Zhang Lei , Wang Pan , Tong Limin
Published: June 2020

Inspired by superficial neuromasts in the lateral line of fish for the sensing of flow rate, we report a bionic optical microfiber flow rate sensor by embedding a U-shaped microfiber into a thin PDMS film. When immersed into liquid, the PDMS film is deflected by the flowing liquid, resulting in a bending-dependent transmittance change of the embedded microfiber which is directly related to the flow rate of the liquid. The flow rate sensor exhibits a low detection limit (< 0.05 L/min), a high resolution (0.005 L/min), and a fast response time (12 ms). In addition, the sensitivity and working range of the sensor are tunable in a wide range via adjusting the thickness of PDMS film, the microfiber diameter, and/or the working wavelength.

Published: June 2020

Higher spatial resolution of the reflection spectrum measurement of Brillouin dynamic grating (BDG) was achieved by controlling phonon power distribution. We experimentally demonstrate the improvement effect of the light-source intensity-modulation method, proposed recently in a correlation-domain technique, and successfully detected an 8-cm cooled section in a 100-m-long polarization-maintaining fiber. Our method can improve the spatial resolution of BDG measurements, leading to high resolution discriminative and distributed fiber sensing of temperature and strain.
Polarization tunable color filters based on all-dielectric metasurfaces on a flexible substrate
Authors: Wang Xiqi , Chen Jingye , Guo Tingbiao , Shi Yaocheng
Published: June 2020

Structural color filters based on all-dielectric materials are considered to be promising alternatives to metal nanostructures due to significant advantages, such as high-quality resonance effects and low losses of Ohmic effects. We demonstrate a polarization tunable color filter based on all-dielectric metasurfaces, which is based on the arrays of asymmetric monocrystalline silicon nanoblocks on the flexible substrate. By adjusting the physical dimensions of nanoblocks, the filter can exhibit a variety of bright transmission colors. Furthermore, the designed dielectric metasurfaces are sensitive to the linear polarization direction of the incident light, thus a wide range of color images can be created by changing the polarization angles. All of the color filter including the dielectric silicon nanoblocks, the overcladding, and the flexible substrate can be delaminated from the handler substrates and the optical property is reconfigurable, which will find applications in the functional color display, polarization detection and imaging, and secured optical tag.

Ultraviolet microdisk lasers are integrated monolithically into photonic circuits using a III-nitride-on-silicon platform with gallium nitride (GaN) as the main waveguide layer. The photonic circuits consist of a microdisk and a pulley waveguide, terminated by out-coupling gratings. In this Letter, we measure quality factors up to 3500 under continuous-wave excitation. Lasing is observed from 374 to 399 nm under pulsed excitation, achieving low-threshold energies of

We present a novel, to the best of our knowledge, Hartmann wave front sensor for extreme ultraviolet (EUV) spectral range with a numerical aperture (NA) of 0.15. The sensor has been calibrated using an EUV radiation source based on gas high harmonic generation. The calibration, together with simulation results, shows an accuracy beyondλ/39root mean square (rms) atλ=32nm. The sensor is suitable for wave front measurement in the 10 nm to 45 nm spectral regime. This compact wave front sensor is high-vacuum compatible and designed for in situ operations, allowing wide applications for up-to-date EUV sources or high-NA EUV optics.
Photonic fractional Fourier transformer for chirp radar with ghost target elimination
Authors: Han Guanyu , Li Shangyuan , Xue Xiaoxiao , Zheng Xiaoping
Published: June 2020

For the first time, to the best of our knowledge, we propose a photonic fractional Fourier transformer (PFrFTer), which is used in chirp radar for detecting multiple non-cooperative targets. Based on photonic rotation of the time-frequency plane, the optimal fractional Fourier domain is formed, and the received broadband chirp signals are projected on it, where they behave as impulses. Moreover, through manipulating the fractional Fourier transform spectrum, the PFrFTer contributes to the cancellation of two ghost target sources, so that the ghost targets in multiple-target circumstances are removed. The simulation and experimental results show that the proposed PFrFTer can adapt to multiple non-cooperative targets environments and is immune to ghost targets at optimal working conditions, which agrees well with the theoretical analysis.

Multinational tax journalism: Devolved UK coverage of corporation tax rates in Scotland and Northern Ireland
Authors: Tunney Sean
Published: June 2020

This article addresses how business and political journalists have covered transnational tax policy, an under-researched area. It analyses coverage of corporate taxation specifically where the power to decide on tax levels is devolved within a multinational state. The work considers how the UK press treated the plans to devolve and reduce corporation tax in Scotland and Northern Ireland, in the context of continued UK-wide reductions. A quantitative and qualitative content analysis illustrates that the sampled opinion and editorial framed around this issue was limited typically to the devolved territories’ ‘hybrid’ editions of the English/UK titles. This was despite the broader impact of varying rates on press readers in the rest of the United Kingdom. Journalists tended to adopt an ‘investor perspective’. A majority of commentary framed around corporation tax was focused on reducing the rate, while rarely considering the implications for government revenue. Nevertheless, importantly, Scottish coverage was bound up with broader political debates on independence.
Generational cohorts’ views on local sustainable practices in fashion
Authors: Palomo-Lovinski Noël
Published: June 2020

The fashion industry is in a state of flux, incongruent with the pace and scale of twenty-first-century consumers. The industry is doing business in a way that is quickly outstripping itself, relying on resources that are disappearing, and dependent on human beings working in unsafe and unfair conditions. The current fashion system relies on constantly providing choice in a short amount of time. This system is reliant on a massive carbon footprint, harming or taking advantage of workers, destroying environments, and which inherently leads to landfills that poison the earth. These practices are short-sighted and in need of change. It is therefore incumbent on those participating in the fashion industry to steer the colossal ship around to support choice, encouraging responsibility, collaboration and kindness, while ensuring physical longevity. This article is a follow-up study that seeks to address the feasibility of a proposed retail and design environment that relies on locality and interaction. The qualitative pilot study examined here focused on women born roughly between 1964 and 1980, also known in the United States as ‘Generation-X’. Women were asked about their understanding of locality, community and sustainability as well as how and what clothing purchases they make. Survey results suggest that women favour a sense of community that emphasizes acceptance, common goals and a learning environment that allows for a non-judgmental interaction and education about sustainable practices. Additionally, the survey supports the proposal of the local retail and design environment.
Sold out or bought in? Complexities of the X Swatch as subcultural accessory for the straight edge scene
Authors: Sklar Monica , Strübel Jessica , Haenfler Ross
Published: June 2020

This research explores lifestyle consumerism and inquires into a subcultural community’s use of a mainstream fashion object to express alternative values. The ‘X-rated Swatch Watch’ is extremely popular within straight edge, a clean-living punk offshoot in which participants abstain from alcohol, tobacco and illicit drugs. Swatch first released the watch in 1987 with a black band and white face featuring a large black ‘X’, a prominent symbol in the straight edge scene visible on clothing, in tattoos and drawn on hands. The limited-edition watch became highly collectable on the second-hand market and was re-released by Swatch in 2018 with design changes, including larger size and more colour options. The first and second incarnations of the watch, as well as knockoffs, indicate aesthetic trends in the fashion cycle, evolutions as well as stagnations in subcultural individual and community expression, and the complexities of a mass market item that has multiple cultural meanings within the same time period. In this article, we use qualitative mixed methods to explore the significance of the watch for United States straight edgers who own or express interest in the watch. Primary data collection included surveys, social media discussions, participant observation and archive visits. Results indicate that wearers utilize this watch to strengthen their straight edge identity and communal connections to similar individuals and to the historic lineage of their lifestyle. X Swatch consumers are not overly concerned with the duality of subcultural and mainstream meanings as they compartmentalize their community from wider society.

Published: June 2020

Many botanic gardens have been contributing to the achievement of Target 8 of the Global Strategy for Plant Conservation (GSPC) through seed banking of wild species. Cibodas Botanic Garden (CBG) seed bank as a part of Kew's Millenium Seed Bank Partnership has also been collecting and banking the seeds of Indonesian native plant species. The study aimed to assess seed availability in nature and collect the available seeds in Selabintana Forest, Mt. Gede Pangrango National Park, West Java, to be stored in the long-term seed storage facility at CBG seed bank. Targeted species for the seed collection were focused on the native trees species with orthodox or approximately-orthodox seeds based on the Seed Information Database (SID) list. Pre-collection assessment and sampling of individuals within a population were using random sampling. Forty seed-producing plant species were reported.  Due  to  the  limitation  number  of seeds in the field (less than 250 seeds), only 33 species were collected. Six species were found with a large quantity of seeds, i.e. Begonia isoptera Dryand. ex Sm., Begonia sp., Ficus fistulosa Reinw. ex Blume, Pinanga javana Blume, Saurauia pendula Blume, and Symplocos sp. Most seeds were collected at 1,100–1,200 m asl, in the forest area, as a tree life form, and majority of the seeds were predicted as desiccation-tolerant (orthodox). Two species, i.e. P. javana and S. cauliflora DC., were listed in IUCN Red List as threatened species. Furthermore, this study demonstrated that high-quality seed collections are needed to ensure the long-term seed conservation.

DISTRIBUSI DAN SIKLUS NUTRIENT DI PERAIRAN ESTUARI SERTA PENGENDALIANNYA
Authors: Yogaswara Deny
Published: June 2020

Nutrient components (consist of nitrogen and phosphorus) are needed for healthy ecosystems and they are naturally widespread throughout the aquatic and terrestrial environment. Nutrient loading as a result of anthropogenic activities comes from rivers that flow into the estuary. The abundance and the cycles of nutrients in the estuary are affected by physical factors (i.e. hydrodynamic conditions such as currents and tides, turbidity and waves), biological factors (i.e. filter feeder organism) and chemical factors (i.e. material fixation and decomposition). To supporting estuarine food webs, phytoplankton and primary productivity are fundamental importance. Besides, they are also key drivers of biogeochemical cycling and play a central role in determining water quality. But on the contrary, within the same conditions, it has negative impact on the estuary environment. The negative impact of high primary productivity in the estuary can cause an algae bloom. Algae bloom occurs when abundant nutrients and optimum sunlight intensity, with the lowest current at the same time. Algae bloom has a negative impact on estuary ecosystems because it makes depleting of dissolved oxygen, with the mass death of marine biota such as fish as a consequence. Therefore, the amount of nutrients from anthropogenic activities have to be controlled and monitored before they flow to the river. The method to control the waste is treated in a Waste Water Treatment Plant (WWTP) system. This treatment by using the WWTP system could reduce the concentration of nutrients spread in the estuary and it will prevent the occurrence of algae bloom phenomena.

Authors: Handayani Tri
Published: June 2020

Rocky shore intertidal occurs at the interface of the land and sea, which regularly exposed with tidal waves. In general, rocky shore intertidal is influenced by extreme physical factors, so organisms need to adapt well. Macroalgae on rocky shore intertidal are mostly macroalgae that have epilithic life foam, for example, Sargassum, Turbinaria, Hypnea, Gracilaria, Amphiroa, Chaetomorpha, Ulva, Acanthophora, and Gelidium. The role of macroalgae on rocky shore intertidal are as a primary producer/primary productivity, food for other organisms (fish, mollusc, sea urchin, crab), nursery ground for other organisms (fish, sea urchin, sea cucumber, and crab), and provide shelter for benthic fauna (crabs, sea urchin, molluscs, polychaeta and sea star). The adaptation of macroalgae on rocky shore intertidal was through morphological changes. Gracilaria salicornia on rocky shore intertidal has slimmer thallus than G. salicornia on non-rocky shore intertidal.

Published: June 2020

A vidék fogalmát és lehatárolását, a vidéki térségek újra strukturálódását, valamint differenciálódását évtizedek óta tudományos diskurzusok övezik. Egységesen elfogadott definíciót nem is találunk a vidékre. Ám arra már sokkal pontosabb koncepciók, meghatározások léteznek, hogy egy hanyatló vidéki terület fellendítése hogyan történhet. Számos nemzeti és szupranacionális programot dolgoztak már ki arra, hogy miként lehet revitalizálni ezeket a térségeket. Mivel ma már nincs akkora dominanciája a vidéki térségekben a mezőgazdaságnak és az iparnak, mint az elmúlt évtizedekben, a szolgáltató szektor nyújtotta lehetőségek tudnak fejlődési lehetőséget biztosítani a rurális régióknak.Jelen írás célja az, hogy a vidékfejlesztés eszköztárát a turizmus felől közelítse meg. Kontextusba kerül a vidékfejlesztés fogalmának értelmezése, az, hogy miként illeszthető ebbe a turizmus, milyen előnyökkel járhat a vidéki turizmus a leszakadó térségekben és milyen összteljesítményből részesülhetnek hazánkban a vidéki turizmus által fellendíteni kívánt térségek.

Published: June 2020

Background The prognosis of neonatal sepsis can be influenced by various risk factors, one of which is a deficiency of zinc micronutrient substances.

Objective To assess for a potential association between serum zinc level and prognosis of infants with early-onset neonatal sepsis (EONS).

Methods This prospective cohort study was done in neonates with clinical EONS from September 2017 until December 2018. Serum zinc level was measured on the first day of diagnosis and prognosis was assessed on the fourth day. The association between serum zinc levels and prognosis of EONS was analyzed by Chi-square test and logistic regression with adjustment for confounding variables.

Results A total of 70 subjects were divided into two groups based on their serum zinc levels. A cut-off point of 75 ug/dL was used based on area under the curve (sensitivity 91.2% and specificity 93.7%), with accuracy 97.8% (95%CI 0.943 to 1.000; P=0.0001). Subjects with lowzinc level had a 16.8 times greater risk compared to subjects with high serum zinc (RR=16.81; 95% CI 4.35 to 65.02; P <0.0001). Multivariate analysis revealed that subjects with low serum zinc levels had 203.7 times greater risk of worsening than subjects who had a higher serum zinc level (RR 203.72; 95% CI 26.79 to 1549.17; P <0.0001). Covariates such as male sex, low gestational age (<37 weeks), low birth weight (<2,500 grams), asphyxia, Caesarean section delivery, and the presence of comorbidities did not have significant associations with outcomes of EONS (P >0.05).

Conclusion Serum zinc level is associated with prognosis of early onset neonatal sepsis, with a cut-off of 75 μg/dL. The high level of serum zinc associates with a better prognosis.

Objective To assess the ability of FOUR scores to predict outcomes of critically ill patients in the PICU.

Methods This prospective cohort study included children aged 1 months - 18 years who were admitted to the PICU. Subjects were assessed by FOUR, grouped into score < 9 or score >9, and followed until outcomes were obtained. Bivariate analysis to assess the risk of death was made by cross-tabulation and the strength of the association in the form of risk ratio by Chi-square test. Multivariate analysis was done by logistic regression test.

Results Of 94 subjects, 47 had FOUR scores ≤9 and 47 subjects had FOUR >9. Bivariate analysis revealed that PICU patients with FOUR score ≤9 had a higher risk of death than those with FOUR score >9 (RR 12.5; 95%CI 3.1 to 49.8; P<0.0001). Multivariate analysis revealed that FOUR score, length of stay ≤7 days, and non-surgical disease significantly increased the risk of mortality in PICU patients (by 42.8 times, 8.9 times, and 5.9 times, respectively).

Conclusion The FOUR scores have good ability to predict the outcomes of critically ill pediatric patients. A FOUR score ≤9 at the beginning of treatment is significantly associated with the outcome of mortality during treatment in the PICU.

Background Nephrotic syndrome causes loss of medium-sized plasma proteins and binding proteins, resulting in thyroid hormone deficiency.

Objective To assess for potential correlations between subclinical hypothyroidism in pediatric nephrotic syndrome with albumin, globulin, and proteinuria.

Methods This cross-sectional study was conducted in the Department of Pediatrics, Hasan Sadikin General Hospital, Bandung, West Java. All types of nephrotic syndrome patients aged 1 month to < 18 years were included. Blood and urine specimens were collected from the patients for albumin, globulin, thyroid function (T3, fT4 and TSH), and proteinuria tests and analyzed with standard techniques.

Results There were 26 subjects, 20 males and 6 females. Ten subjects developed subclinical hypothyroidism, with mean albumin and thyroid-stimulating hormone (TSH) levels of 0.92 g/dL and 6.9 mIU/L, respectively. There was a negative correlation between albumin level and subclinical hypothyroidism (rpb=-0.702; P<0.001) and a positive correlation between proteinuria and subclinical hypothyroidism (r=0.573; P=0.003). Univariate logistic regression analysis revealed that globulin had no impact on the presence of subclinical hypothyroidism, but albumin and proteinuria did have such an impact. The odds ratios of albumin and proteinuria with subclinical hypothyroidism were 27.00 (95%CI 1.69 to 17.7) and 19.80 (95%CI 1.94 to 201.63), respectively.

Conclusion Subclinical hypothyroidism correlates with serum albumin level and proteinuria in nephrotic syndrome patients. Tha low serum albumin level has a high likelihood of subclinical hypothyroidism.
The Experience of Organizing the First Travelling Art Exhibitions in Russia (1871-1890s)
Authors: Valkova K.V.
Published: June 2020

This article discusses the main goals of organizing the first traveling art exhibitions in Russia and specific measures for their implementation by members of the Association of the Wanderers (“Peredvizhniki”). The borrowing by artists of the idea of the second half of 19th century holding traveling exhibitions in Western countries is noted. The implementation of such exhibitions in the Russian Empire was made possible largely due to the emergence of technical capabilities, namely the development of railway communication. Despite the fact that the Wanderers proclaimed as their goal the acquaintance of the provinces with the achievements of domestic art, they focused on the capitals and large cities of the empire. The analysis of exhibition attendance and the process of a gradual increase in the cities covered by the Wanderers is given. The ambiguous perception of the Partnership and their exhibitions in society is considered, which is reflected in the periodical press of that period of time. An analysis of sources and research on the topic led to the conclusion about the successful experience of the Partnership in organizing traveling exhibitions in Russia. In support of this is the fact of adopting the experience of holding exhibitions in a similar format at various levels, including the Imperial Academy of Arts.
Evolution of the Bashkir-Turkmen Ethnocultural Interaction from the Middle Ages to the Present Day
Authors: Ayupov T.M.
Published: June 2020

The article is devoted to the close historical and ethnocultural relations between the indigenous inhabitants of the Ural-Volga region and Turkmenistan, existing since the Middle Ages. According to Eastern authors, at that time part of the Bashkirs lived on the Syrdarya and in the Aral Sea region, along with the ancestors of the Turkmens, from where, due to political upheavals, some moved to the interfluve of the Urals and the Volga, while others moved to the Amudarya and further to the Transcaspian. Of particular interest for the development of our theme are similar subjects in Bashkir and Turkmen folklore. For comparison, several Bashkir traditions recorded by P. Nazarov, N. Maliev, R. Kuzeev and others are given in the work. The mention of Oguz-Khan, Turkmenistan, Turkmen khans, the wolf is common for folklore, especially the south-eastern Bashkirs. Other sources often mention Gorkut-Ata — the hero of the Oguz epic. A large number of ethnonymic parallels with the Turkmens also speak about the Oguz origin of some Bashkir clans. In the names of the settlements of Bashkortostan, the ethnonym “Turkmen” is also recorded. There are other similarities: both nations profess Islam, and the Turkmen language, in a number of phonetic features, draws close to Bashkir. Since 1993, the Turkmen Cultural Center has been actively operating in Bashkortostan. Republic representatives take part in many international forums, often held recently in Ashgabat.
