Authors: CHENG Warman W. M. , CARRE Alex F. , KIM Ku , CARR Robin
Published: March 2021

LANGUAGE NOTE | Document text in English; abstract also in Chinese.The purpose of this study was to do a comparative analysis of the critical coaching interventions surrounding the use of timeouts employed by male university coaches. Little examination of such game related coaching decision making as a measure of coaching effectiveness has been conducted, particularly at the international level. Fifty-five male coaches of men’s university basketball teams from four different countries (Canada, Hong Kong, South Korea, Taiwan) were analyzed using a questionnaire consisting of demographic questions and a specific six-factor, 26-item timeout questionnaire. Analysis of variance with Scheffe post hoc multiple comparisons was used to examine the results. The findings were: 1. Canadian and South Korean coaches were older and more experienced than coaches from the other countries with Canadian coaches holding more formal certification qualifications. 2. Age, experience and qualifications, however, made no statistically significant difference to the overall results. 3. The "physical" factor was the most common reason for calling timeouts with Hong Kong coaches using this reason most often. 4. The "emotional" factor was the least used reason for calling timeouts for Canadian coaches but was used most often by Korean coaches. 5. Canadian coaches were less likely to use timeouts while Korean coaches were most likely. Canada and Taiwan scored consistently higher than Hong Kong and South Korean coaches and were more similar in their emphasis on all factors. The results suggest a clear difference in the approach to timeout decision making among the coaches from the four countries with the Canadian strategy being consistently different than the other countries of Hong Kong, Taiwan and especially South Korea. The highest emphasis on "physical" factor indicated the importance of using timeouts as a means of controlling team fatigue and energy expenditure.本研究之目的在於分析大學男子籃球敎練在使用暫停的關鍵抉擇。以往較少研究使用比賽中敎練的決定去分析敎練的敎授成效，本問卷以六種決策方式，分26項來分析四個國家(加拿大、香港、南韓及台灣)的大學男子籃球隊敎練的決策因素，並分析跨國的異同關係。研究指出：一. 加拿大及南韓的敎練年齡較長、經驗較深，而加拿大敎練具有較多正規的証書資格。二. 年齡、經驗及資格與決定因素並無明顯的相關。三. 香港敎練較常以體能因素去請求暫停。四. 加拿大敎練較少以心理因素去請求暫停，而反之南韓敎練則較多。五. 加拿大敎練較少請求暫停而南韓敎練則較多。而在整體因素方面，加拿大及台灣敎練的取向相似並較香港及南韓敎練為高。結果指出加拿大敎練在請求暫停的決定方面與其他國家有明顯的分別，以南韓為甚。體能因素備受重視則引出暫停用作控制球隊疲累及能量消耗問題的重要性。

Prophet Muhammad p.b.u.h., moved (hijrah) from Mecca al-Mukarramah to Medina al-Munawwarah, then founded the state of Medina by gathering the national strength of the Muslim, Christian and Jewish population with the identity of the Quraish, Auz, and Khazraj tribes. Caliph Ali bin Abi Talib moved the capital of the Rashidah Caliphate from Medina to Kufa, form Arab to the Persian region. Muawiyah bin Abu Sufyan chose Damascus as the capital of the Umayyah dynasty. Abu Abbas al-Safah placed the seat of the Abbasid dynasty in Baghdad. Furthermore, the Ottoman Empire had its capital in Istanbul. After turning into the Republic of Turkey, it occupies Ankara as the capital. Planning of moving the capital city of the Republic of Indonesia is from the Province of the Special Capital Region (DKI) Jakarta to the Province of East Kalimantan intended as an effort to equalize development that strengthen togetherness in a sense. The ideological, political, social, cultural and legal foundations serve as the basis of legitimacy in the historical footsteps of the Paser Kingdom and the Kutai Kartanegara Kingdom, as the center of government of the Republic of Indonesia. The theory of development ('umran), urban theory ('urban), and the theory of nationality ('asabiyah) put forward by Ibn Khaldun in the Muqaddimah have become methodological conceptions in studying maritime-based archipelago construction. This research shows the point of the new State Capital (IKN), in the archipelago network from Sabang to Merauke. A blueprint for the nation's journey that covers the dynamics of human resource potential in the natural resource management system of the republic of Indonesia.
High pH, Low Alkalinity Pond Water Used for Overhead Irrigation Does Not Affect Plant Growth of Select Flowering Shrubs1
Authors: LeBude A.V. , Owen J.S. , Holmes C.
Published: March 2021

In southeast U.S., pH of source water from ponds used for overhead-irrigating container crops can exceed the range (pH 5.8-7.0) for best management practices. Artificially maintaining this pH range is not common among producers using surface water for irrigation, nor is it known whether this would affect growth. Therefore, the objective was to test whether this source water affects growth of five flowering shrubs in nurseries in eastern North Carolina. Pond water at six nurseries with a pH range of 4.9-8.1 (control) was injected before irrigation with sulfuric acid (lower) or potassium bicarbonate (raise) onsite to maintain a pH of 5.8-6.2 (treatment). Ambient photosynthesis (Aambient) and stomatal conductance (gs) was measured in July, August, and September on leaves of forsythia (Forsythia x intermedia 'Mindor‘ ShowOff®) during irrigation runtime mini-experiments at three nurseries. For mini-experiments, pre- and post-treatment physiology was measured for plants receiving 0 (hand watered), 30, or 60 minutes of treated or nontreated overhead irrigation. Dry weight of all shrubs and gas exchange of forsythia was not affected by high pH, low alkalinity (<100 ppm) irrigation water. Southeastern producers using this source water for overhead irrigation may not need to adopt a system that reduces pH to improve growth.

Index words:, Container-grown, plant physiology, photosynthesis, stomatal conductance, ornamental.

Chemicals used in this study: Potassium bicarbonate, sulfuric acid.

Species used in this study: fragrant abelia, Zabelia tyaihyonii (Nakai) Hisauti & H.Hara 'SMNAMDS‘ Sweet Emotion®; butterfly bush, Buddleia x ‘Miss Molly'; border forsythia, Forsythia x intermedia ‘Mindor‘ Show Off®; panicled hydrangea, Hydrangea paniculata Siebold ‘SMHPLQF' Little Quick Fire®; landscape rose, Rosa x ‘ChewPatout' Oso Easy®.

La dialéctica del trabajo universitario ha sido reinventarse todo el tiempo por las circunstancias cambiantes, está así desarrollado en el libro, y hoy más que nunca toma mayor relevancia ante las actuales circunstancias del mundo. Es una constante que los actores, profesores y estudiantes, y las instituciones mismas tomen su tiempo para adaptarse a las nuevas circunstancias. Por eso, al interior mismo de las universidades se presenta el fenómeno de la intraducibilidad y la incomunicabilidad, porque las personas ubicadas en diferentes paradigmas tienen muchas dificultades para comprender y adaptarse a las nuevas exigencias. Este libro de 132 páginas es el resultado de diversas investigaciones que confluyen en los cuatro capítulos desarrollados, los paradigmas, las complejidades, las percepciones y las necesidades. Se hace especial énfasis en todo lo relacionado con el aprendizaje, y el cambio en el trabajo de los docentes quienes deben usar las diferentes alternativas de interacción didáctica y sobre todo hacer mucho énfasis en el valor de los nuevos conocimientos, explicando su importancia y su aplicabilidad en la comprensión de los fenómenos o en la solución de los problemas de su entorno.
Att balansera pedagogiska positioner i förskolans undervisning: en fallstudie om hur förskolepersonal hanterar pedagogiska dilemman
Authors:   , Narkaj Adolfsson Paulina
Published: March 2021

Förskolans uppdrag förändras mot ett större fokus på undervisningoch skapandet av förutsättningar för barn att utveckla förmågor inom olika innehållsområden. Samtidigt kvarstår förskolans centralamål som utgår från barns intressen, arbeta målövergripande och utifrån strävansmål. Hur personal hanterar denna balansgång mellan ett förstärkt fokus på undervisning utifrån olika innehållsområden, fokus på barns intressen och målövergripande arbete ligger till grund för denna studie. Mer specifikt riktas fokus mot hur en personalgrupp i samtal tolkar och gör verksamhet i förhållande till ett delvis förändrat uppdrag. Studiens syfte är att bidra med kunskap om vilka pedagogiska positioner förskolepersonal intar för att hantera dilemman som uppstår i förskolans verksamhet. Genom att ta fasta på vilka dilemman personal försöker hantera genom att inta positioner synliggörs hur genomförande av förskolans uppdrag innefattar ett balanserande mellan motstridiga krav Agevall & Jenner, 2008). Materialet har samlats in genom deltagande observation och bestårav fyra inspelade reflektionssamtal vid en förskoleavdelning för barn 1–3 år. Samtalen utgick från dokumentation om ett pågående matematikprojekt och hur personalen valde att agera i verksamheten. I analysen av det empiriska materialet används tre centrala begrepp; pedagogiska positioner, scenarier och dilemman (Hundeide,2006). Studiens resultat visar att personalen i sina samtal intar och pendlar mellan fyra pedagogiska positioner i hanterandet av identifierade dilemman. De pedagogiska positionerna visar att personalen balanserar mellan positioner och olika sätt att förstå och genomföra sitt uppdrag. En övergripande slutsats är att förskolans komplexa uppdrag kräver att personalen balanserar mellan och intar olika pedagogiska positioner som integreras och kompletterar varandra när pedagogiska dilemman hanteras och undervisninggörs. Det innebär att undervisning i förskolan handlar om ett mångfacetterat agerande och inte om att välja ’antingen eller’.
Arrival Time Matters: The Effect of Biculturalism and Age of Arrival on College Adjustment
Authors: Tan Guicheng
Published: March 2021

The present study aimed to examine how Chinese bicultural students adjust to college using the Bicultural Integration Identity (BII) framework and the ways BII interact with other variables. Seventy-five Chinese bicultural students between the age of 18 through 35 completed an online survey assessing their BII levels, social capital, acculturative stress, and college adjustments. Using regression analysis, participants’ BII levels were a positive indicator for their college adjustment, (p = .02, r² = .13), bridging social capitals (p = .01, r² = .11), and a negative indicator for acculturative stress related to discrimination (p = .03, r² = .12). Additionally, there was a significant interaction effect between BII levels and participants’ age of arrivals in the United States. BII levels were only a positive indicator of dependent variables for participants who arrived in the United States between the ages of 6 through 17. However, BII acted as a negative indicator for participants who arrived after 18 years old. This study revealed that BII levels improve students’ adjustment to college, but only for those who arrived in the United States during middle childhood and adolescence. Possible limitations and implications on students’ identity development and college transition were discussed.

Published: March 2021

Subject. We analyze and evaluate the possibility of developing the ‘smart city’ concept, in particular, its ‘smart culture’ aspect. The relevance of the study increases in conditions of the quarantine, which causes restrictions on movement and visit to cultural institutions, like theaters, museums, libraries, etc.
Objectives. The purpose is to identify the potential to improve the quality of life in the ‘smart culture’ direction, by assessing the capabilities of theaters in the Novosibirsk Oblast; to develop new indicators from the perspective of the digital economy.
Methods. We use the statistical analysis of indicators that reflect the activities of cultural institutions. The study also employs the comparative analysis of indicators of Russia and the Novosibirsk Oblast in this sphere.
Results. The paper analyzes trends in the number of professional theaters, spectators, and the share of theaters, having their websites in the Novosibirsk Oblast and Russia. We obtained the results of processed questionnaires and surveys of the population. On this basis, we formulated new indicators of the quality of life of the population for the ‘smart culture’ direction, and assessed the potential for its development under quarantine.
Conclusions. The analysis shows that the ‘smart city’ concept has been developing, despite the introduction of quarantine measures to protect the population. Such measures as the development of websites and information portals that increase the accessibility of events (performances, exhibitions, etc.) for the population are in demand.
Quantitative parameters of anti-money laundering regulation
Authors: TANYUSHCHEVA Nataliya Yu.
Published: March 2021

Subject. As financial institutions carry out a huge number of transactions, the financial sector definitely needs to automate some control procedures, including anti-money laundering ones. The effectiveness of automated control measures directly depends on how adequately tasks for the software are written. The article examines the impact of macroeconomic indicators, such as GDP per capita, average wage, and the scale of the shadow economy in the G20 countries and in two of the CIS countries (Belarus and Tajikistan) on thresholds of the fixed limit of transaction (FLT), which is regulated with the anti-money laundering legislation, including the fixed limit of cash transaction (FLCT).
Objectives. I investigate approaches to setting FLT (FLCT) in different countries and formulate my opinion on this issue.
Methods. The methodological basis of the study was made up of empirical and logical constructions, statistical analysis, synthesis, systems approach.
Results. I identified why FLT (FLCT) are denied. This happens due to lawmakers’ confidence in the effectively controlled financial sector, or the corruption pressure. The countries with FLT (FLCT) introduce and use them formally. The article presents the risk-based approach to measuring the FLCT based on the macroeconomic indicators (average annual wages, savings per capita).
Conclusions and Relevance. The case of Russia shows that the inflation undermines the barrier function of FLT (FLCT), while the analytical division of financial intelligence has to handle more issues. The proposed approach will help reduce costs the financial system incurs to process financial information in order to counter money laundering.

In the context of government action as a center point relate to public law protection, state administration jurisdiction along with its function as “judicature” (justiele functie – judicial function) belongs to characteristic of and/or repressive function. However, norm of Article 21 in Act Number 30 in 2014 about State Administration provide authority to State Administration Court to conduct assessments, whether there is any abuse of authority in decision making and/or administrative action (discretion) requested by an institution and/or an official of government administration, brings legal implication in form of a change in legal politic direction related to law enforcement in corruption crime eradication in this country in forms of preventive efforts, which is similarly as important as the corruption crime eradication itself, because corruption crime prevention is a condition sine qua non in corruption crime eradication. Based on the condition of characteristic and/or functions of state administration judiciary which is not merely repressive (merely functioning as “judiciary”), this writing attempts to provide basic of understanding to the judicial development of state administration along with its preventive roles and functions which are related to law enforcement in corruption crime eradication in forms of or types of state financial lost as it is legally defined in law ratio of norm of Article 21 in Act of government administration.
Surface code quantum error correction incorporating accurate error propagation
Authors: Fowler Austin G. , Wang David S. , Hollenberg Lloyd C. L.
Published: March 2021

The surface code is a powerful quantum error correcting code that can be defined on a 2-D square lattice of qubits with only nearest neighbor interactions. Syndrome and data qubits form a checkerboard pattern. Information about errors is obtained by repeatedly measuring each syndrome qubit after appropriate interaction with its four nearest neighbor data qubits. Changes in the measurement value indicate the presence of chains of errors in space and time. The standard method of determining operations likely to return the code to its error-free state is to use the minimum weight matching algorithm to connect pairs of measurement changes with chains of corrections such that the minimum total number of corrections is used. Prior work has not taken into account the propagation of errors in space and time by the two-qubit interactions. We show that taking this into account leads to a quadratic improvement of the logical error rate.
Characterization of universal two-qubit Hamiltonians
Authors: Childs Andrew M. , Leung Debbie , Mancinska Laura , Ozols Maris
Published: March 2021

Suppose we can apply a given 2-qubit Hamiltonian H to any (ordered) pair of qubits. We say H is n-universal if it can be used to approximate any unitary operation on n qubits. While it is well known that almost any 2-qubit Hamiltonian is 2-universal, an explicit characterization of the set of non-universal 2-qubit Hamiltonians has been elusive. Our main result is a complete characterization of 2-non-universal 2-qubit Hamiltonians. In particular, there are three ways that a 2-qubit Hamiltonian $H$ can fail to be universal: (1) H shares an eigenvector with the gate that swaps two qubits, (2) H acts on the two qubits independently (in any of a certain family of bases), or (3) H has zero trace (with the third condition relevant only when the global phase of the unitary matters). A 2-non-universal 2-qubit Hamiltonian can still be n-universal for some n \geq 3. We give some partial results on 3-universality.
Generation of cluster-type entangled coherent states using weak nonlinearities
Authors: An Nguyen B. , Kim Kisik , Kim Jaewan
Published: March 2021

We propose a scheme to generate a recently introduced type of entangled coherent states using realistic weak cross-Kerr nonlinearities and intense laser beams. An intense laser can be filtered to make a faint one to be used for production of a single photon which is necessary in our scheme. The optical devices used are conventional ones such as interferometer, mirrors, beam-splitters, phase-shifters and photo-detectors. We also provide a detailed analysis on the effects of possible imperfections and decoherence showing that our scheme is robust against such effects.
Local extrema of entropy functions under tensor products
Authors: Friedland Shmuel , Gour Gilad , Roy Aidan
Published: March 2021

Localization of quantum walks on a deterministic recursive tree
Authors: Xu Xin-Ping
Published: March 2021

Localization of quantum walks can be characterized by the return probability, i.e., the probability for the walker returning to its original site. In this paper, we consider localization of continuous-time quantum walks in terms of return probability on a deterministic recursive tree, which is generated by adding one node and connecting it to each node of the existing tree recursively. We obtain an approximate form for the return probability using the complete eigenvalues and eigenstates of Laplace matrix of the structure. It is found that the return probability depends on the initial node of the excitation. When the walk starts at the central nodes, the return probability converges to a constant value even in the limit of infinite system, in contrast to an exponential decay of the return probability if the walk starts at the outlying nodes. We also observe a bipartite structure for the distribution of return probability, and provide theoretical interpretation for all our findings. Our results suggest that quantum walks display significant localization and well-bedded structure of return probability on heterogeneous trees.
Entanglement distribution over the subsystems and its invariance
Authors: Tong Qing-Jun , An Jun-Hong , Luo Hong-Gang , Oh C. H.
Published: March 2021

We study the entanglement dynamics of two qubits, each of which is embedded into its local amplitude-damping reservoir, and the entanglement distribution among all the bipartite subsystems including qubit-qubit, qubit-reservoir, and reservoir-reservoir. It is found that the entanglement can be stably distributed among all components, which is much different to the result obtained under the Born-Markovian approximation by C. E. L\'{o}pez et al., and particularly it also satisfies an identity. Our unified treatment includes the previous results as special cases. The result may give help to understand the physical nature of entanglement under decoherence.
Unstructured randomness, small gaps and localization
Authors: Farhi Edward , Goldstone Jeffrey , Gossetr David , Gutmann Sam , Shor Peter
Published: March 2021

We study the Hamiltonian associated with the quantum adiabatic algorithm with a random cost function. Because the cost function lacks structure we can prove results about the ground state. We find the ground state energy as the number of bits goes to infinity, show that the minimum gap goes to zero exponentially quickly, and we see a localization transition. We prove that there are no levels approaching the ground state near the end of the evolution. We do not know which features of this model are shared by a quantum adiabatic algorithm applied to random instances of satisfiability since despite being random they do have bit structure.
An exact tensor network for the 3SAT problem
Authors: Garcia-Saez Artur , Latorre Jose I.
Published: March 2021

We construct a tensor network that delivers an unnormalized quantum state whose coefficients are the solutions to a given instance of 3SAT, an NP-complete problem. The tensor network contraction that corresponds to the norm of the state counts the number of solutions to the instance. It follows that exact contractions of this tensor network are in the \#P-complete computational complexity class, thus believed to be a hard task. Furthermore, we show that for a 3SAT instance with $n$ bits, it is enough to perform a polynomial number of contractions of the tensor network structure associated to the computation of local observables to obtain one of the explicit solutions to the problem, if any. Physical realization of a state described by a generic tensor network is equivalent to finding the satisfying assignment of a 3SAT instance and, consequently, this experimental task is expected to be hard.
Improving quantum clocks via semidefinite programming
Authors: Mullan Michael , Knill Emanuel
Published: March 2021

The accuracies of modern quantum logic clocks have surpassed those of standard atomic fountain clocks. These clocks also provide a greater degree of control, because before and after clock queries, we are able to apply chosen unitary operations and measurements. Here, we take advantage of these choices and present a numerical technique designed to increase the accuracy of these clocks. We use a greedy approach, minimizing the phase variance of a noisy classical oscillator with respect to a perfect frequency standard after an interrogation step; we do not optimize over successive interrogations or the probe times. We consider arbitrary prior frequency knowledge and compare clocks with varying numbers of ions and queries interlaced with unitary control. Our technique is based on the semidefinite programming formulation of quantum query complexity, a method first developed in the context of deriving algorithmic lower bounds. The application of semidefinite programming to an inherently continuous problem like that considered here requires discretization; we derive bounds on the error introduced and show that it can be made suitably small.
Quantum predictive learning and communication complexity with single input
Authors: Gavinsky Dmitry
Published: March 2021

We define a new model of quantum learning that we call \e{Predictive Quantum (\pq)}. This is a quantum analogue of \pac, where during the testing phase the student is only required to answer a polynomial number of testing queries. We demonstrate a relational concept class that is \e{efficiently learnable} in \pq, while in \e{any} ``reasonable'' classical model exponential amount of training data would be required. This is the first unconditional separation between quantum and classical learning. We show that our separation is the best possible in several ways; in particular, there is no analogous result for a functional class, as well as for several weaker versions of quantum learning. In order to demonstrate tightness of our separation we consider a special case of one-way communication that we call \e{single-input mode}, where Bob receives no input. Somewhat surprisingly, this setting becomes nontrivial when relational communication tasks are considered. In particular, any problem with two-sided input can be transformed into a single-input relational problem of equal \e{classical} one-way cost. We show that the situation is different in the \e{quantum} case, where the same transformation can make the communication complexity exponentially larger. This happens if and only if the original problem has exponential gap between quantum and classical one-way communication costs. We believe that these auxiliary results might be of independent interest.
Airway Management of COVID 19 and Low Cost Ventilators - A boon or bane
Authors: Shristi Verma
Published: March 2021

Corona viruses are a large group of infectants that caused illness in humans and animals. In human it spreads through contact between people which is observed with MERS and SARS. Close contact leads to the spread of this deadly virus through the droplets from cough, sneezes or talks. The incubation period ranges between 2-14 days which is still uncertain in many a lot of cases. Depending on the symptoms disease has been categorized for the management, thus mild symptoms with sore throat, fever, cough and malaise are treated with antipyretic and antitussives with nutritive care. For moderate symptoms oxygen therapy, Anticoagulation, corticosteroids is given with antiviral drugs, demand for the supply must be maintained. WRT the severe cases drug therapy should be continued and oxygenation maintained early in the disease, with the progression of disease to ARDS ventilation protocol is taken into action firstly with non-invasive procedure supplying oxygen by the mask or the nasal cannula and maintaining the SpO2 and FiO2. If the condition worsens the Lung no longer acts compliant endotracheal intubation is performed for implementation of mechanical ventilation in the setting with access to expertise. For the patients who undergoes septic shock, patient is started on antimicrobial therapy, fluid loadings maintained and vasopressors given. Glucocorticoids can be used for short duration for the worsening condition of the patient.

The student environment is one of the most intense and intense places of interethnic contacts. Traditionally, in an educational institution, an important way to improve the educational process, which involves comfortable psychological interpersonal relationships, is to develop methods that contribute to the formation of interethnic tolerance. The North Ossetian state medical Academy is a modern multi-level system of continuous training of specialists of higher medical and pharmaceutical education belonging to different national confessions. An important activity of SOGMA is the development of international relations and cooperation with foreign students.

HYPOADAPTIVE STRATEGY OF MEANING BUILDING AS A MANIFESTATION OF PERSONALITY INFANTILISM
Authors: I.V. Abakumova , A.V. Grishina , M.V. Godunov
Published: March 2021

The processes of meaning building act as adaptive mechanisms for the reaction of the experiencing individual to changes in the external and internal world. The building of personal meanings is based on a s meaning choice that reflects the preferences of the individual in the direction of his development. The mismatch and unevenness of the biological, mental and social development of a person can lead to an insufficient level of adaptation in the form of personality infantilism. Such immaturity of the personality may be associated with incomplete formation of the emotional-volitional sphere, due to the predominance of children's character traits, the influence of upbringing and relationships with parents. The reasons for personal infantilism are the constant acceleration of scientific and technological progress, cultural variability of society, unclear prospects for life development, high competition in the professional and social sphere. An infantile person experiences difficulties in terms of regulating his activities, lack of reflection, has gaps and deformations in moral self-regulation. This leads to shortcomings in the value- meaning, educational, legal, political, socio-economic, family spheres, in the field of vocational guidance and development. Such a passive adaptation of the s meaning sphere as an insufficient manifestation of the key personality traits in situational interactions reflects a hypoadaptive meaning strategy. Signs of a mature personality: competent professional work and independent development in the chosen field of activity, stable personal and family relationships, subjectivity in relations with parents in the form of territorial and economic independence, consistent development of the range of mental, social roles and transcendental roles in various social groups, the ability to personal self-determination of the experiencing subject in relations with other people.
COMPARATIVE ANALYSIS OF AGE PERCEPTIONS ABOUT STEREOTYPICAL AND IDEAL GENDER QUALITIES IN MODERN SOCIETY
Authors: I.V. Galaktionov
Published: March 2021

This article examines the problem of gender socialization and identity in modern Russian society, on the basis of an analysis of ideas about the typical and ideal gender characteristics of the personality is compared to three age groups (up to 20 years - generation q, 20-40 years - Generation Y and 40-60 years - generation X) and concludes on the main trends in the development of gender characteristics of the individual in groups of different gender and age. The study obtained new empirical data on age and sexual differences in perceptions of typical and ideal qualities of gender, in particular, found that the age of women significantly influences their ideas about the male and female gender ideal, the age of men significantly influences their perception of the male gender ideal, members of different generations of the south significantly differ in ideas about the female gender ideal, the representatives of different generations Y significantly differ in ideas about the female gender ideal , the biological sex in the age group X influences the idea of male gender ideal. At the same time, there were no statistically significant differences between gender and age in the perception of typical male and female qualities. The results can be an important material for a differentiated approach to family counselling and assistance in building harmonious inter-sex relationships.

Acesso e Transição nos Níveis Representacionais durante a Construção de Modelos Explicativos acerca de Interações Intermoleculares
Authors: Fernandes Bruno Gumieri , Locatelli Solange Wagner
Published: March 2021

A química pode ser compreendida por meio de três níveis representacionais: macro, submicro e o simbólico, sendo que a relação entre eles precisa ser adequadamente estabelecida. Visando investigar esses aspectos, essa pesquisa teve como objetivo compreender os níveis representacionais acessados pelos alunos, suas dificuldades e o papel da estratégia metavisual durante a elaboração de modelos explicativos acerca de interações intermoleculares. Para isso, participaram 3 graduandos de uma universidade pública brasileira, durante a disciplina de Práticas de Ensino de Química II. Todo o processo foi documentado com base em gravações audiovisuais, contemplando a técnica “think aloud”, em que os alunos analisados criaram desenhos propondo modelos explicativos para misturas, considerando-se as interações intermoleculares presentes. Posteriormente, foram feitas as transcrições e a partir delas, algumas categorizações. Os resultados indicaram que os alunos conseguiram fazer transições entre os níveis, sendo mais preponderantes as transições referentes ao submicro, mesmo sendo o de maior abstração. Utilizaram o macro de forma reflexiva, possibilitando transições com o submicro para validação de modelos, enquanto para o simbólico foram apresentados entraves relacionados às representações. Com relação à atividade metavisual, inferiu-se que contribuiu de forma satisfatória no entendimento dos níveis representacionais, uma vez que possibilitou um intenso exercício metacognitivo de construção e reconstrução de conceitos científicos. Finalizando, neste trabalho foi proposto um novo modelo de categorização para os níveis representacionais, considerando-se tanto o acesso como a transição nos níveis representacionais.

Colors have special importance in keeping the emotions alert in the painting. Colors help us in the euphoria of our feelings of happiness, sorrow, excitement, euphoria etc. Colors are helpful in the morphological representation of human emotions. The color is not only the color of the picture, it also expresses the solar heat of the spring, the roaring of the clouds and the fountains of the soil soaked by rain. When the element of color is understood, then black color also fills the light of knowledge. That is why prehistoric humans used mineral colors to engrave their emotions on the rock, in which ocher, ramaraj, coal, chariot and hirauji, etc. are the main colors. In fact, these colors were the basis for the display of prehistoric human expressions.

चित्रकला में भावनाओं को सजग रखने में रंगो का विशेष महत्व होता है। रंग हमारे सुख-दुख उत्तेजना, भय, उल्लास आदि सभी भावनाओं के उद्वीपन में सहायक होते है। रंग मनुष्य के मनोभावों के रूपात्मक प्रस्तुतिकरण में सहायक होते है। रंग केवल चित्र की रंगत ही नही है, यह बसन्त के सौरभ को सूर्य के उत्ताप को, मेघों के गर्जन को और वर्षा से भीगी मिट्टी के सौधंे पन को भी व्यंजित करते है। रंग का तत्व जब समझ में आ जाता है तो काला रंग भी ज्ञान का आलोक भर देता है। इसलिये तो प्रागौतिहासिक मानव ने अपने मनोभावो को शिला पर उकेरने के लिए खनिज रंगो का प्रयोग किया जिसमें गेरू, रामरज, कोयला, खड़िया एवं हिरौजी, आदि प्रमुख रंग है। वास्तव में ये रंग प्रागौतिहासिक मानव के भावों के प्रदर्शन का मूलाधार थे।

With our favorite color, we can get complete information about the mentality of an individual world.The color of light - Why do we get different colors in the rainbow? This fact was discovered in 1665 by Newton. He had succeeded in getting his seven ingredients on the screen after passing through the prism of white light. When the sun passes through the prism of light, the seven-color group formed on the screen by the rays of the sun is called the spectrum of white light - purple, purple, blue, green, yellow, orange and red. This phenomenon of dividing the seven elements of white light into colors is called varna paranpana.
