Purpose: A valid and reliable tool that could measure patient satisfaction with physical therapy care for Persian-speaking patients will improve communication and enhance the involvement of people in research on health care quality and disparities. We aimed to evaluate the psychometric properties of the Persian version Physical Therapy Patient Satisfaction Questionnaire (PTPSQ). Methods: In this cross-sectional study, a prospective validation study design was adopted. In this methodological study, 297 patients from several physiotherapy centers in Kerman City, Iran, were evaluated using the PTPSQ. After the seventh session, a demographic questionnaire, visual analog scale, and the global rating of change were also answered by the participants (time point 1). The psychometric evaluation included factor analysis, divergent validity, convergent validity, and analysis of floor and ceiling effects. Reproducibility and internal consistency were investigated in this regard. To assess the test-retest reliability, 40 participants (randomly selected) completed the PTPSQ, again 24 to 48 hours later (time point 2). This research project was reviewed and approved by the Ethics Committee of the University of Social Welfare and Rehabilitation Sciences, Tehran, Iran. SPSS v. 24 was used for statistical analysis. Results: The interclass correlation coefficient was in the range of 0.80-0.94 with the Cronbach alpha coefficient of 0.92. The standard error of measurement, minimal detectable change, and coefficient of variation for the questionnaire were 5.14, 14.39, and 0.21, respectively. Factor analysis revealed the 3-factor model. The relationship between the PTPSQ scores and the patient satisfaction index was relatively good (>0.40). Conclusion: Our results showed strong psychometric properties of the PTPSQ. Thus, we recommended its use in the Persian-speaking population.

Published: June 2021

El objetivo de la presente investigación es visibilizar los efectos alienantes de la descultura lectora, como toma de consciencia docente para apropiarse de la cultura lectora, desde la pedagogía de la praxis. El enfoque de la investigación es mixto, desde la óptica de un diseño no experimental y un tipo investigativo de carácter bibliográfica, descriptiva y de campo. Para recabar la información empírica se aplicó una encuesta basada en un cuestionario de cinco interrogantes, a toda la población de docentes del Colegio de bachillerato “Ciudad de Portovelo”. Esta información permitió concluir que, los informantes presentan un contundente desconocimiento sobre lo consultado: en un 87.5% sobre la cognición situada propuesta por Vigotsky, en un 75%, respecto al contexto de la descultura lectora, en un 95.83% en torno a la cultura lectora o práctica cultural, en un 100% sobre el contexto de apropiación y en un 91.67% referente a la praxis por Freire. Lo que evidencia que los educadores presentan falencias formativas, conceptuales y metodológicas respecto a su praxis pedagógica proyectada a promover la cultura lectora en los educandos. Por lo que se recomienda, socializar el presente estudio entre el profesorado, para que tome consciencia de los efectos negativos de la descultura lectora, en los educandos y se apropie de los lineamientos de la cultura lectora, desde la cognición situada, la apropiación y la praxis como práctica social transformadora.

Authors: Dankevych Stepan
Published: June 2021

The problem of ensuring the balanced use of forest lands determines the search for new economic and environmental tools that can influence this process. The need to improve the certification tool as part of the financial and economic mechanism for ensuring balanced forestry land use corresponds to the directions of state policy and European integration intentions of Ukraine, modern requirements of the ecological aspect of forestry land use. The work examines the practice in the field of forest certification in Ukraine from the point of view of balanced land use. Spatial-temporal analysis and assessment of the scale and dynamics of the spread of forest FSC certification in Ukraine has been carried out. The study was formed in three stages: (I) study of changes over time in the volume of forest certification on a national scale, (II) assessment of trends over time for indicators on a regional scale, (III) study of the relationship between individual indicators. The analysis of the impact of FSC-certification of forest management in Ukraine on the environmental indicators of forestry land use based on the results of the correlation between the statistical characteristics of certain economic and environmental indicators, such as the area of certified forests, capital investments, reforestation. Analysis of statistical data showed the relationship between environmental and economic performance over time and changes in specific characteristics on a regional scale. The study makes it possible, on the basis of an objectively existing causal relationship between phenomena and indicators, to identify the course of certain positive or negative processes in forestry land use. Forest certification can play a role in maintaining a balanced use of forest lands, preventing illegal logging, forest degradation and contributing to reforestation and capital investments. The study helps to identify certain key variables that limit the ability of forestry operators to ensure balanced use of forest lands and how forest certification can affect this. Foreign experience in stimulating forest certification has been investigated for the possibility of borrowing the experience of using management tools in order to motivate forest certification in Ukraine. It has been proven that certification is a significant environmental tool for ensuring a balanced level of land use and has the potential for further development.

Authors: Klymenko Iryna , Komchatnykh Olena , Kryvenko Olena
Published: June 2021

The article examines the shadow economy as a phenomenon and its features. The shadow economy is a phenomenon that accompanies almost every economy, both developed and undeveloped. There is no common and clearly defined understanding of the essence and classification of the concept of shadow economy. The country's shadow economy exists as a result of the interaction of psychological and cultural factors that cannot be influenced in the short term. A feature of the shadow economy is a significant adaptability to external factors, a certain flexibility and ability to self-regulate. Indicators are indicated that have a significant impact on the dynamics of the size of the shadow economy. Approaches to determining the reasons for the existence of the shadow economy are given. Separately, the main reasons for the growth of the shadow economy in the developed countries of the world are indicated in percentage terms. The level of shadowing of the economy is investigated using various methods. The features of the shadow labor market and its components are considered. The shadow market is provided by the discrepancy between the actual and formal conditions for hired workers. The concept of shadow employment, the number of informally employed population in general and by type of economic activity and the reasons for the existence of the shadow labor market are analyzed. Shadow employment hinders the normal formation of state budget revenues. In order to estimate the size of the shadow economy, methods are used that can be divided into three groups: direct, indirect and mixed. There has been a decrease in the actual number of informally employed people, which is associated with the COVID 19 pandemic, which forced the economies of countries to reduce the number of both formal and informal workers. Non-observance of social norms and non-payment of taxes completely violate a kind of agreement between the population and the state, leading to a crisis of governance and distrust in the mechanism of state regulation and a significant decrease in macroeconomic indicators. Measures are recommended to reduce the level of the shadow economy.
Increasing Returns to Scale in Carpool Matching: Evidence from Scoop
Authors: Lehe Lewis , Gayah Vikash V. , Pandey Ayush
Published: June 2021

Systems that depend on matching often exhibit scale economies, whereby increased participation leads to improved performance for all users. This paper examines the presence of such increasing returns to scale in carpool matching. Data from Scoop, a carpooling app, is used to demonstrate this phenomenon across various markets using regression. As the number of requests to carpool in a certain market rises, the share of proposed matches that users accept rises, while the extra distance traveled to accommodate these carpools declines. These relationships hold in four specifications of the regression model, and they suggest there are increasing returns to scale in matching.

Authors: Jamilu R. Y. , Asambe A.
Published: June 2021

Clinical bacterial isolates from chickens were analysed to determine their susceptibilities to antimicrobial agent. Ten (10) Escherichia coli and 8 non lactose fermenting Enterobacteriaceae species isolated from a pool of clinical cases of chickens from Microbiology Laboratory of the Veterinary Teaching Hospital, University of Agriculture Makurdi were used for the study. Enrofloxacin with 99 % purity obtained from Sigma-Aldriech, USA and prepared in varying concentrations (0.1 - 50μg/mL) was used in vitro by Kirby-Bauer’s disc-diffusion method. The isolates were susceptible to enrofloxacin at a minimum concentration of 25 (μg/mL) and the mean value in the zones of inhibition exhibited by Escherichia coli and non-lactose fermenters were significantly different (p<0.01). The enrofloxacin tested also exhibited the concentration dependent effect typical of quinolones in this study. The study concluded that the tested antimicrobial agents can still be applied in the prevention and treatment of bacterial infection of chickens. Usage of these agents by veterinarians in poultry with appropriate clinical judgement and proper dosing principle is recommended. Also, routine assessment of the in vitro activities of this agent against common microbial infections in this area is strongly recommended

Numerical Study on Natural Convection of Alumina-water Nanofluid in a Square Cavity with Two Localized Heat Sources on Adjacent Surfaces
Authors: Shaik Farooq , Domakonda Vinay Kumar
Published: June 2021

In the present work, results of a numerical study carried out using finite volume method, to investigate the fluid flow and heat transfer characteristics of Alumina ( Al2O3 ) nanoparticles in the base fluid (water) in a square cavity under natural convection mode are presented. The Semi Implicit Method for Pressure Linked Equations (SIMPLE) algorithm was used to solve the discretized momentum and energy equations. Constant temperature heat sources of same strength are placed on bottom and left vertical surfaces whereas the right surface was kept cold, while the top surface was maintained as adiabatic. The impact of Rayleigh number (RaN) ( 1000 to 106 ) and nanoparticles volume fraction (Φ = 0 %, 5 %, 10 %, 15 % and 20 %) on fluid and heat flow characteristics were numerically investigated and presented in the form of streamlines, isothermal lines, mid line horizontal and vertical velocity components, local Nusselt number ( Nuloc ) and average Nusselt number ( Nuavg ). The obtained results indicate, for lower RaN ( i.e; 103 ), conduction dominates over convection near heated surfaces and results in lower fluid velocities and poor heat transfer. For higher values of RaN ( RaN = 105 and 106 ) and volume fraction of nanoparticles, there was a significant increase in mid horizontal and vertical velocity components, Nuloc and Nuavg due to increase in convective heat transfer and thermal conductivity of nanofluid.

The research libraries thoroughly analyze new information resources emerging on the information market as well as the dynamics and vectors of information and communication processes in science. The author discusses the findings of the study of acquiring the proceedings of scholarly events to the collections of the Library for Natural Sciences of the Russian Academy of Sciences. This type of publications comprises information on the most recent developments, vectors in fundamental and applied research accomplished by national and foreign research organizations. With this information resource, researchers are able to find like-minded colleagues and to assess their own possibilities and prospects for their own studies. The reference materials, conference proceedings and other scholarly publications are of undoubtful interest to the scholarly community; however, the circulations are small, and, as a rule, the book-selling organizations do not distribute these publications. The circulation depends on the number of participants attending the scholarly event. Therefore the conference, symposium, seminar proceedings can be categorized as rare publications. The accumulated experience of collection development with these publications enables to analyze other types of small-circulation scientific publications acquired to the collections of the library.

Authors: Savitskaya T. E.
Published: June 2021

The author discusses the current experience of building the service of digital science publishing obtained by the libraries in the Western countries. She emphasizes that this process is incorporated into further informatization of libraries and their increasing role in managing science data. The digital publications integrate a number of interrelated programs comprising the whole cycle of scientific data management accomplished within the wider context of innovations. Digital publishing is a new type of library activities; it requires integrating competences of modern librarians (i.e. content selection, data supervising, metadata management, building digital collections, their preservation and archiving) and publishers (monitoring new trends in science and technology, selecting materials for publication, abstracting, scientific editing, developing marketing strategies).

For the first time in the domestic library studies, the dynamics of this service in foreign countries is examined based on Library Publishing Directory for 2013– 2018. The author compares digital publishing services in four university libraries in different world regions and offers the findings of preliminary analysis of online publication services in foreign research libraries.

A lot of assistance is usually given from the government to the community and must be managed by the village government so that the aid gets to the right hands. And to improve food security, the people in each region have activities to distribute Poor Rice as a subsidy from the government. In the distribution method, sometimes there are constraints in data collection so that poor rice or what we usually call Raskin is not suitable for distribution. Because of this, a way is needed so that the distribution is appropriate or not in the community in accepting the Raskin so that government assistance can be delivered properly and on target. By using secondary data obtained from Bencoy Village, 205 data were obtained containing the attributes of the eligibility category of Raskin recipients, and 6 categories of attributes were found with the classification method of the Naïve Bayes algorithm. The accuracy value obtained is 96.59%, proving that the prediction using the Naive Bayes algorithm has a good performance. The next results obtained are in the form of AUC value which after being calculated produces a value of 0.999 and this results in an application which is an implementation with a flow that is adjusted to the calculation algorithm in the form of a web-based application.
Preconditions for CMIP6 models to reproduce the relationship between wintertime ENSO and subsequent East Asian summer rainfall
Authors: Fu Y , Lin Z , Wang T
Published: June 2021

The El Niño-Southern Oscillation (ENSO) in the preceding winter (December-January-February) is one of the key factors affecting subsequent East Asian summer (June-July-August) rainfall (EASR). However, current models face great challenges in reproducing ENSO’s impact on the EASR. This study attempts to reveal the factors that determine whether a model in phase 6 of the Coupled Model Intercomparison Project (CMIP6) can successfully reproduce this relationship by analyzing the outputs of historical climate simulation in 20 CMIP6 models. The results show that most of the models that overestimated ENSO interannual variability reproduced significant ENSO-EASR relationships, whereas all models that underestimated ENSO variability failed to reproduce this relationship. Further analyses show that models with stronger ENSO variability tended to simulate more realistic physical processes linking ENSO and EASR, i.e. the connections between ENSO and the tropical Indian Ocean (TIO) sea surface temperature (SST), between TIO SST and the Philippine Sea convection (PSC), and between PSC and EASR. Moreover, among the models that overestimated ENSO variability, only those that successfully captured significant TIO SST-PSC connections reproduced the observed ENSO-EASR relationship, although all these models captured ENSO-TIO SST and PSC-EASR teleconnections well. Therefore, simulating stronger ENSO interannual variability is the first necessary precondition for a CMIP6 model to capture the delayed effect of ENSO on EASR; reproducing a realistic TIO SST-PSC teleconnection is the second necessary precondition. This study will help models to improve their skills in simulation and prediction of EASR.

The black-capped petrelPterodroma hasitatais an Endangered seabird endemic to the western North Atlantic. Although estimated at ~1000 breeding pairs, only ~100 nests have been located at 2 sites in Haiti and 3 sites in the Dominican Republic. At sea, the species primarily occupies waters of the western Gulf Stream in the Atlantic and the Caribbean Sea. Due to limited data, there is currently no consensus on the geographic marine range of the species although no current proposed ranges include the Gulf of Mexico. Here, we report on observations of black-capped petrels during 2 vessel-based survey efforts throughout the northern Gulf of Mexico from 2010-2011 and 2017-2019. During 558 d and ~54700 km of surveys, we tallied 40 black-capped petrels. Most observations occurred in the eastern Gulf, although birds were observed over much of the east-west and north-south footprint of the survey area. Predictive models indicated that habitat suitability for black-capped petrels was highest in areas associated with dynamic waters of the Loop Current. We used the extent of occurrence and area of occupancy concepts to delimit the geographic range of the species within the northern Gulf. We suggest that the marine range for black-capped petrels be modified to include the northern Gulf of Mexico, recognizing that distribution may be more clumped in the eastern Gulf and that occurrence in the southern Gulf remains unknown due to a lack of surveys there. To date, however, it remains unclear which nesting areas are linked to the Gulf of Mexico.

Studying the at-sea movements and behaviour of juvenile seabirds is logistically challenging, but new technologies now allow tracking birds on their first migration, giving a more complete picture of population-level spatial ecology. We investigated the post-fledging migration of juvenile northern gannets Morus bassanus from the world’s largest colony, at Bass Rock, Scotland. We first examined the movements and survival of 38 juveniles over their initial days at sea with GPS precision for up to 53 d post-fledging. We then compared their migration journeys with those of 35 adults tracked with geolocators. Almost one-third of juveniles died within 2 mo of leaving the colony, and this mortality was often associated with apparent uncertainties in their direction of migration, including marked, abrupt and often repeated changes in bearing within the North Sea. Both juveniles and adults then migrated as far as the Canary Current Large Marine Ecosystem (CCLME) off the Atlantic coast of West Africa, initially taking both clockwise and counter-clockwise routes around the UK. Juveniles covered a distance each day similar to that of adults, but they reached the CCLME much more quickly, mainly because they travelled more directly, staying close to the coast throughout most of their migration, whereas adults additionally spent long periods over relatively restricted areas of ocean further offshore. The CCLME is a hotspot of unregulated fishing activity, and our findings highlight the importance of this region across different age-classes of birds, echoing previous calls that the regional strengthening of marine conservation should be a high priority.

A renalis osteodystrophia (ROD) kezelése az új osteoporosisajánlások ismeretében a jelenlegi terápiás megközelítés újragondolását igényli. A D-vitamin-hiány rendezése és a csonttörés okozta életminőség-romlás mérséklése a veseelégtelen populációban is fontos szakmai kihívás. A ROD klasszikus nefrológiai kezelésével elérhető eredmények javítása az újabb molekuláris patomechanizmusok megismerésétől, a jobb képalkotó módszerektől várható. A vascularis kalcifikációval kapcsolatban felismert összefüggések a cardiovascularis szövődmények megelőzésére irányuló törekvéseinket segíthetik, a fogágybetegségekkel mutatkozó kapcsolat a rendszeres ellenőrzés jelentőségét támasztja alá. A foszforkötők, D-vitamin-agonisták és kalcimimetikumok mellett a jövőben várható a reszorpciógátló denosumab, a csontfelépítő folyamatokat támogató PTH-analógok, valamint a romosozumab szélesebb körben történő klinikai alkalmazása.
Mechanics of Global Value Chains: India's Perspective
Authors: Dutta Sourish
Published: June 2021

Global production as a system of creating values is eventually forming a vast web of value chains. It explains the transitional structures of world trade and the development of the world economy. It is truly a new wave of globalisation, and we term it as the global value chains (GVCs), creating the nexus among firms, workers and consumers around the globe. It requires analysing the statics and dynamics of different economic players involved in this complex global production network. Its widespread notion deals with diverse global, regional, and local issues from the top-down to bottom-up, building scope for policy analysis. In this context, this study will attempt to quantify the extent and impacts of India's engagement in GVCs, based on available data. It will also strive to propose a comprehensive strategic framework to identify the objectives of India's GVC participation and development with some suitable economic strategies to achieve them.

Resonate are interested in looking at different strategies / models / techniques for dealing with the problem of rescheduling a railway timetable when it's unexpectedly disrupted, the likely strengths and risks of these, and how they might be adapted to improve existing solutions. Nine different approaches (drawn from machine learning, network models and stochastic models) to defining the efficiency of a station in dissipating delays were considered. They fell broadly into two groups: those that sought to understand the propagation of delays and those that sought to offer strategies for minimising delays.

The transdifferentiation of adipose-derived mesenchymal stem cells (ADMSCs) into insulin-producing cells (IPCs) is a potential resource for the treatment of diabetes. However, the changes of genes and metabolic pathways on the transdifferentiation of ADMSCs into IPCs are largely unknown. In this study, the transdifferentiation of canine ADMSCs into IPCs was completed using five types of procedures. Absolute Quantitative Transcriptome Sequencing Analysis was performed at different stages of the optimal procedure. A total of 60,151 transcripts were obtained. Differentially expressed genes (DEGs) were divided into five groups: IPC1 vs. ADSC (1169 upregulated genes and 1377 downregulated genes), IPC2 vs. IPC1 (1323 upregulated genes and 803 downregulated genes), IPC3 vs. IPC2 (722 upregulated genes and 680 downregulated genes), IPC4 vs. IPC3 (539 upregulated genes and 1561 downregulated genes), and Beta_cell vs. IPC4 (2816 upregulated genes and 4571 downregulated genes). The gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis of DEGs revealed that many genes and signaling pathways that are essential for transdifferentiation. Hnf1B, Dll1, Pbx1, Rfx3, and Foxa1 were screened out, and the functions of five genes were verified further by overexpression and silence. Foxa1, Pbx1, and Rfx3 exhibited significant effects, can be used as specific key regulatory factors in the transdifferentiation of ADMSCs into IPCs. This study provides a foundation for future work to understand the mechanisms of the transdifferentiation of ADMSCs into IPCs and acquire IPCs with high maturity.

Growth differentiation factor 11 (GDF11) is a member of the transforming growth factor β superfamily that alleviates cardiac hypertrophy, myocardial infarction, and vascular injury by regulating oxidative stress, inflammation, and cell survival. However, the roles and underlying mechanisms of GDF11 in diabetic cardiomyopathy (DCM) remain largely unknown. In this study, we sought to determine whether GDF11 could prevent DCM. After establishing a mouse model of diabetes by administering a high-fat diet and streptozotocin, intramyocardial injection of an adeno-associated virus was used to achieve myocardium-specific GDF11 overexpression. GDF11 remarkably improved cardiac dysfunction and interstitial fibrosis by reducing the levels of reactive oxygen species and protecting against cardiomyocyte loss. Mechanistically, decreased sirtuin 1 (SIRT1) expression and activity were observed in diabetic mice, which was significantly increased after GDF11 overexpression. To further explore how SIRT1 mediates the role of GDF11, the selective inhibitor EX527 was used to block SIRT1 signaling pathway, which abolished the protective effects of GDF11 against DCM. In vitro studies confirmed that GDF11 protected against H9c2 cell injury in high glucose and palmitate by attenuating oxidative injury and apoptosis, and these effects were eliminated by SIRT1 depletion. Our results demonstrate for the first time that GDF11 protects against DCM by regulating SIRT1 signaling pathway.
Roles and Mechanisms of DNA Methylation in Vascular Aging and Related Diseases
Authors: Xu Hui , Li Shuang , Liu You-Shuo
Published: June 2021

Vascular aging is a pivotal risk factor promoting vascular dysfunction, the development and progression of vascular aging-related diseases. The structure and function of endothelial cells (ECs), vascular smooth muscle cells (VSMCs), fibroblasts, and macrophages are disrupted during the aging process, causing vascular cell senescence as well as vascular dysfunction. DNA methylation, an epigenetic mechanism, involves the alteration of gene transcription without changing the DNA sequence. It is a dynamically reversible process modulated by methyltransferases and demethyltransferases. Emerging evidence reveals that DNA methylation is implicated in the vascular aging process and plays a central role in regulating vascular aging-related diseases. In this review, we seek to clarify the mechanisms of DNA methylation in modulating ECs, VSMCs, fibroblasts, and macrophages functions and primarily focus on the connection between DNA methylation and vascular aging-related diseases. Therefore, we represent many vascular aging-related genes which are modulated by DNA methylation. Besides, we concentrate on the potential clinical application of DNA methylation to serve as a reliable diagnostic tool and DNA methylation-based therapeutic drugs for vascular aging-related diseases.
