Published: August 2022

The issue of organizing the educational process in the distance format is one of the most actual in the last two years in the education sphere. Accordingly, this is due to the fact that there are a number of disciplines, which in turn require the direct presence of students, one of which is physical education. Given the above, it should be noted that the purpose of this work is to analyze the basic tools and mechanisms for the implementation of physical education classes in higher education, in the context of distance learning. To achieve this goal, the article used a list of methodological tools for research. Thus, an important role was played by functional and systemic methodological approaches, as well as the method of analysis and synthesis, the method of comparison, the method of analysis of scientific literature. The main results that were obtained directly as a result of the study are both theoretical and practical principles of organizing physical education classes for students in distance learning. Accordingly, at the beginning of the work the essence of the basic theoretical concepts of the researched question, and also their signs and properties were established. If we talk about the practical component, then it analyzes the main approaches and tools used by Ukrainian free economic zones at the moment. The practical value of the work certainly lies in the fact that it can be used by both teachers and students in addressing organizational issues related to the implementation of physical education classes in the fight against the COVID-19 pandemic.
PASOLINI IN SALENTO. NON-ACADEMIC ANTHROPOLOGY IN THE POST-WAR ITALY
Authors:   Russian Presidential Academy of National Economy and Public Administration, Litvin Evgeniya A.
Published: August 2022

An object of Pasolini’s interest was not only Rome or Friuli, the connection with which can be explained by his biography, but also remote regions of the south of the country. The latter in the 1950s–1960s were under scrutiny not only of the institutional anthropologists, religious scholars and folklorists, but also of the general public of intellectuals. A surge of such interest arose due in large part to the work of the religious historian Ernesto De Martino, who wrote several monographs focused on Lucania, Sicily, and the Salentine Peninsula. The paper focuses on the work of Pasolini in the field of documentary filmmaking on the Salentine Peninsula in 1955–1974 in the context of the theoretical ideas of that time, as well as on the influence that such an experience had on Pasolini’s further cinema works.

A Latent Class Modeling Approach for Differentially Private Synthetic Data for Contingency Tables
Authors: Nixon Michelle , Barrientos Andres , Reiter Jerome , Slavkovic Aleksandra
Published: August 2022

We present an approach to construct differentially private synthetic data for contingency tables. The algorithm achieves privacy by adding noise to selected summary counts, e.g., two-way margins of the contingency table, via the Geometric mechanism. We posit an underlying latent class model for the counts, estimate the parameters of the model based on the noisy counts, and generate synthetic data using the estimated model. This approach allows the agency to create multiple imputations of synthetic data with no additional privacy loss, thereby facilitating estimation of uncertainty in downstream analyses. We illustrate the approach using a subset of the 2016 American Community Survey Public Use Microdata Sets.
Overlook: Differentially Private Exploratory Visualization for Big Data
Authors: Budiu Mihai , Thaker Pratiksha , Gopalan Parikshit , Wieder Udi , Zaharia Matei
Published: August 2022

Data exploration systems that provide differential privacy must manage a privacy budget that measures the amount of privacy lost across multiple queries. One effective strategy to manage the privacy budget is to compute a one-time private synopsis of the data, to which users can make an unlimited number of queries. However, existing systems using synopses are built for offline use cases, where a set of queries is known ahead of time and the system carefully optimizes a synopsis for it. The synopses that these systems build are costly to compute and may also be costly to store.
We introduce Overlook, a system that enables private data exploration at interactive latencies for both data analysts and data curators. The key idea in Overlook is virtual synopsis that can be evaluated \emph{incrementally}, without extra space storage or expensive precomputation. Overlook simply executes queries using an existing engine, such as a SQL DBMS, and adds noise to their results. Because Overlook's synopses do not require costly precomputation or storage, data curators can also use Overlook to explore the impact of privacy parameters interactively. Overlook offers a rich visual query interface based on the open source Hillview system. Overlook achieves accuracy comparable to existing synopsis-based systems, while offering better performance and removing the need for extra storage.

First Row Transition Metal Complexes Derived from N, Nʹ-Substituted Thiourea: Synthesis, Geometrical Structures and Cyclic Voltammetry Probe: A Review
Authors: Al-Riyahee Ali A. A.
Published: August 2022

Thioureas or thiourea derivatives as organosulfur compounds are one of the most widely used ligands in different applications as we are going to discuss it extensively such as in coordination chemistry by involving them to rich sources of N, O and S atoms coordinating through S atom, S and O atoms in benzoyl derivatives or S, O and N atoms in pyridyl hetrocylic benzoyl derivatives. These hard and soft donor sites facilitate the bonding between thiourea free ligand and metal ion through one or more to make ligands behave as mono, bi or multidentate ligands to form huge and stable series of the metal complexes. The tautomerism (thiol↔thione) inside the thiourea derivatives is responsible on their flexibility which make them easy capable to coordinate in different modes. Thiourea derivatives and their metal complexes are known in biological area by possess them antibacterial, antifungal, antimalarial, antitubercular, antithyroid and insecticidal activity features. Thioureas used as vital reagent to separate metal ions, catalyst to synthesize organic compounds or as starting material to form different hetrocyclic compounds. The wide range applications of thioureas and their metal complexes has motivated specialized researchers to search new applications for these compounds and to create a novel derivatives. The goal of this article is to present historical survey of thioureas and their metal complexes focusing on: firstly, the development of their synthetic routes by explore reactants, products, catalysis and the conditions of reactions. Secondly: investigation of the geometrical shapes of the produced complexes are reviewed as well as to the coordinated sites with metal centers. Lastly, the electrochemical manners have been lighted by employing cyclic voltammetry (CV) to study the electrochemical behavior of free ligands and their complexes to confirm the oxidation state of the metal ion in its complexes.

Authors: Hadi Janan Abdelkrim Abbas
Published: August 2022

The wheat plant, Triticum aestivum L., is one of top cereal crops in the world, followed by the rice and corn crops; and it is one of the most important food crops for more than a third of the world's population. in recent times, several studies focused on finding ways to increase and encourage growth and production of wheat, and among these methods is the use of nanomaterials. The present study has been conducted to evaluate the nanomaterials titanium dioxide (TiO2) and zinc oxide (ZnO) efficacy in the growth promoting of three cultivars of wheat plant (Ibaa 99, Abu Ghraib and Bhooth 22). Laboratory experiments proved the non-toxicity of TiO2 and ZnO on the germination of wheat seeds. All treatments were 100% germinated, whereas the results showed the superiority of TiO2 in stimulating all examined parameters. The examined parameters, whether in Petri plates or pots, including the length of the radicle and hypocotyl, compared to a control treatment. The results of the pots experiment showed that the concentration of 100 ppm significantly exceeded the rest of the tested concentrations (0, 25 and 50 ppm), and the Abu Ghraib cultivar was the most responsive to nanomaterials. It is worth noting that the nanomaterials TiO2 and ZnO at a concentration of 100 ppm led to an increase in some biochemical indicators, including photosynthesis pigments, carbohydrate content and proline, compared to the control treatment in the cultivar Abu Ghraib .The current study recommends that TiO2 and ZnO should be used in the treatment of wheat plants, with more studies being conducted on other economic plants.

Authors: Hidayah Sri Noor Mustaqimatul
Published: August 2022

This study aims to examine the concept of exchange and the role of money according to Ibnu Miskawaih. This research on the concept of exchange and the role of money is carried out by using a library research approach, namely, by recording all findings and combining all findings, both theories or new findings from books, websites, articles and newspapers on the study of the concept of exchange and the role money according to Ibn Miskawaih. The results of the study show that Ibn Miskawayh's Islamic Economics thought a lot about the exchange of goods and services and the role of money. According to him, humans are social beings who need each other to meet the needs of goods and services. Therefore, humans will exchange goods and services with appropriate compensation (riward, al-mukafad al-munasibah). Humans act as assessors and balancers (al-muqawwim al-musawwi baynahuma) in exchange so as to create justice. Ibn Miskawaih also discussed the advantages of gold coins (dinar) which are widely accepted and become substitutes (mu'awwid) for all types of goods and services. This is because gold is a metal that is durable, easy to carry, not easy to imitate, desired and loved by many people

Mathematical investigative ability is one of the skills that need to be honed in every student to improve problem-solving skills and develop thinking skills. A mathematical investigation has four stages: specialization, conjecture, justification, and generalization. This paper aims to describe the mathematical investigative abilities of extroverted and introverted personality students. This study was conducted qualitatively on Junior High School 1 Mataram students in grades IX-F, selected by a simple random sampling technique. Based on the mathematical investigation test results and personality type, 6 students were selected to be interviewed. The results showed that extrovert students were alert, independent, and outward-looking or oriented when doing mathematical investigation tests, such as directly working on questions deftly and trying out their ideas. Therefore, students with extrovert personalities mostly succeeded in going through three stages of an investigation, namely: specialization, conjecture, and justification. Introvert personality students, when doing mathematical investigations, are thorough, detailed, focused, and think deeply, such as checking answers by doing one more time, then rereading the answers in detail, and focusing on thinking deeply at the generalization stage. Therefore, most introverted students passed three stages of mathematical investigation: specialization, conjecture, and justification. However, some introverted students also made it through the fourth stage.

This study aims to describe the differences in the critical thinking ability of male and female students at junior high school (SMPN 27 Surabaya) on environmental pollution topics. The type of research used is descriptive. The research sample was 34 students of SMPN 27 Surabaya class VII F consisting of 17 female students and 17 male students. Data collection was carried out using critical thinking skills tests, student questionnaires, and learning observation sheets. The data obtained include students' critical thinking skills, observation results, and interview results that have been grouped based on the student's gender. The results of this study show that there are differences in critical thinking skills between male students and female students. Female students scored an average critical thinking ability of 75, while male students scored 65. The critical thinking ability of female students is higher than that of male students, as evidenced by the average score of female students being higher than that of male students. It shows that in learning activities, teachers must pay attention to student gender differences, motivate students, and choose the appropriate learning model.
