The aim of the work is to determine the optimal temperature regime for firing chromium ore and the consumption of solid carbon, which ensures the recovery of chromium. The process of chromium reduction was investigated on a model elementary system by reducing chromium from ore with solid carbon. The areas of redox conditions in the Cr-C-O system were identified, the boundaries of the reduction, transition and oxidative regions were revealed. The temperature required for the recovery process was determined by calculating the equilibrium compositions of the Cr2O3 + nC system in the temperature range 1100-1900 K at n = 1, 2, 3, 4 and 5 moles.

. The object of works has been the barite-bearing technogenic wastes. The wastes include the final tailings of the Karagailinsky mining and processing plant. They are stored in the tailing dumps, and they have been formed during the flotation concentration of the barite-polymetallic ores of the Karagaily deposit [1-2]. These tailing dumps occupy a huge territory. Thus, the dumps are pollution sources of soil, air and water by the heavy metals and barite dust. These wastes have been not recycled yet, i.e. there is no effective technology that would allow the cost-effective production of the quality commercial products. The issue with the barite-bearing waste recycling is its complex mineralogical composition. Thus, it leads to the inefficiency of the traditional recycling methods such as the acid leaching and flotation [3-5]. In order to solve these issues on this raw materialrecycling, some methods should be found to explore the ore mineral aggregateswith the silicon-bearing gangue minerals [6-7]. A promising solution to the issueis to explore the raw materials with the chemical methods, in particular, by a method of ammonium fluorosulfate desiliconization. Studies have been performed to explore the barite raw material by the sintering with ammonium fluorosulfate. As a result, a mathematical model of the exploration has been created and the optimal conditions for this process have been determined. The partial dependences of the raw material exploration on temperature, sintering time and consumption of the exploring reagents have been obtained. Based on the partial dependencies, a mathematical model of the sintering as a generalized multifactor equation has been created. This equation has determined the optimal conditions to explore the barite raw materials. A scheme of ammonium fluorine sulfate exploration of the barite raw materials has been developed

Дүниежүзілік жануарлар денсаулығы ұйымының мәліметі (ДЖДҰ) бойынша, әлемде құс тұмауы бойынша эпизоотиялық жағдай әлі де күрделі. Жоғары патогенді құс тұмауы – вирус тудыратын, өте жұқпалы, жіті өтетін, пантропты ауру. Аурудың клиникалық белгілері, патологиялық-анатомиялық өзгерістері және құстардың әртүрлі инфекцияларының эпизоотиялық деректерінің өте ұқсастығына байланысты ауруды тек зертханалық әдістермен ғана дәл ажыратуға болады.

Ауруға балауды кешенді түрде қояды: эпизоотологиялық мәліметтер, клиникалық белгілері арқылы және зертханалық балау әдістері. Кешенді балаудың  түпкілікті нәтижесі зертханалық диагностикалық әдістерге негізделген, сол әдістердің бірі – гемаглютинацияны тежеу реакциясы (ГАТР).

Зерттеу жұмыстары «Қазақ ғылыми зерттеу ветеринария институты» ЖШС-нің вирусология зертханасында жүргізілді. Қазақстан Республикасының кейбір аймақтарының жеке қосалқы шаруашылықтарындағы үй құстарына мониторинг жүргізу барысында сынамалар алынып, кешенді серологиялық әдістер қолданылды. Серологиялық реакцияларда А типті құс тұмауы вирусының H5 кіші типті телімді антиденелері кешенді зерттеу кезінде үй құстарының қан сарысуларында анықталды. Осы сарысуларда Ньюкасл вирусына қарсы антиденелер табылған жоқ. Вакцинацияланбаған құстардың H5 кіші типті құс тұмауы вирусына қарсы антиденелер ГАТР-да 7 log2 (1:128) титрде оң нәтиже көрсетті.

Вакцинацияланбаған құстардан алынған қан сарысуларында құс тұмауы вирусына қарсы антиденелердің титрі жоғары қан сарысуы халықаралық стандартты сарысумен салыстырмалы стандартталғаннан кейін тест-жиынтықтардың сапасын тексеру мақсатында ұлттық стандартты қан сарысу ретінде қолдануға болады.

В статье представлены результаты молекулярно – генетической экспертизы животных герефордской породы крупного рогатого скота. Был проанализирован аллелофонд молодняка по 15 микросателлитным локусам ДНК ( BM2113, BM1824, ETH10, BM1818, ETH3, INRA023, TGLA227, TGLA126, TGLA122, TGLA53, SPS115, ETH225, CSSM66, ILSTS006 и CSRM60). Количество аллелей в отдельных локусах микросателлитов варьировало от 4 в локусах ETH3, BM1824, ETH10 до 8-9 в локусах TGLA53, BM2113, CSSM66, в среднем на локус приходилось 5,8 аллелей и в сумме составило 87 аллелей. Локус CSSM66 является самым высокополиморфным из всех 15-ти локусов микросателлитной ДНК крупного рогатого скота (уровень полиморфности 4,695), тогда как локус INRA023 - наименее полиморфным (1,672). Средний показатель уровня полиморфности составил 3,204. В результате генотипирования бычков герефордской породы по изучаемым микросателлитным локусам значения наблюдаемой гетерозиготности (Ho) и ожидаемой (He) варьировали в пределах 0,355 - 0,935 и 0,402 - 0,787 соответственно. Средние показатели наблюдаемой и ожидаемой гетерозиготности имели сходные значения (0,675 и 0,666), индекс фиксации имел величину, равную минус 0,011. Таким образом, были выявлены основные характерные особенности полиморфизма по всем изученным микросателлитам ДНК бычков герефордской породы.

В статье изложены материалы результаты исследования адаптация разных генерации герефордской и абердин-ангусской пород к температуре окружающей среды северного региона Казахстана.

По результатам исследований, можно сделать вывод о том, что животные ІІ и ІІІ  генерации имеют наибольшую приспосабливаемость к повышенной температуре окружающей среды, для чего им требуется меньшее напряжение защитных сил организма. У этих групп животных более совершенная система терморегуляции, которая позволяет более рационально использовать ресурсы организма в жаркую погоду, характерную для летних месяцев в условиях северного региона Казахстана.

При сравнении вышеизложенных данных можно придти к выводу, что показатели температуры тела, дыхательной системы и сердечной деятельности молодняка ІІ генерации, полученного от импортированного скота мясного направления абердин-ангусской породы при разведении в минусовых температурах в условиях cеверного Казахстана указывают на среднюю степень адаптированности их организма.

По нашим исследованиям оптимальной температурой для І и ІІ генерации герефордской и абердин-ангуской пород в условиях Северо-Казахстанской областей зона термонейтральности или комфортной температуры находится в пределах +19-22...+27-31°С.

Наша республика является самой северной среди стран, заготавливающих хлопок, поэтому особое внимание уделяется созданию и выращиванию раннеспелых сортов. В настоящее время период созревания выведенных в зарубежных странах сортов длится 150-160 дней, а для полученных в нашей стране сортов достаточно 110-125 дней.

Генетический потенциал рода Gossypium в селекционной работе использован неудовлетворительно, хотя можно предположить, что среди сортообразцов и диких видов коллекции имеются доноры засухоустойчивости.

   Для создания новых исходных форм хлопчатника основным источником является мировая коллекция. Потребность в новых и продуктивных формах с хозяйственно – ценными параметрами исходного материала хлопчатника диктует необходимость постоянного поиска и синтеза генотипов для пополнения ген ресурсов и создания конкурентоспособных сортов хлопчатника. Генетические ресурсы растений представляют биологическую основу продовольственной безопасности и жизнеобеспечения любой страны. Решение вопросов сохранения устойчивого использования генетических ресурсов растений являются основной целью Конвенции по Биологическому Разнообразию (СВД,1992) подписанной Казахстаном в числе 152 стран мира. Поэтому исследования и работы по формированию, изучению, сохранению и поддержанию генофонда хлопчатника, а так же выведение новых сортов на основе коллекций образцов актуальны во всех хлопкосеющих странах, в том числе и в Республике Казахстан. Для создания новых исходных форм хлопчатника основным источником пополнения является мировая коллекция. Крупные банки генофонда хлопчатника сосредоточены в Китае, США, Узбекистане, Пакистане, Индии и др.

В данной статье приведены данные по исследованию депигментация волосяного покрова каракульских ягнят бухарского сура. Актуальность проблемы, заявленной в статье обусловлена изменениями обмена меланина в клетках кожи, при котором появляются участки неравномерно окрашенного волосяного покрова овец. Целью данного исследования являлось изучение депигментации окраски волосяного покрова  овец  бухарского сура в онтогенезе. Основным методом, применяемым в процессе исследования, был объективный метод. Организовывались наблюдения от рождения до созревания взрослых особей. С помощью наблюдения отмечались изменения в шерстяной окраске овец. Сравнивались на предмет проявления депигментации окраски шерстного покрова  отдельных участков тела каракульских овец  бухарского сура. Тело баранчика оценивалось при рождении по интенсивной, нормальной и ослабленной выраженности окраски с помощью визуального и сравнительного метода в течении жизни. Рассматривались различные факторы, которые могут повлиять на изменения в волосяном покрове каракульских овец. В статье представлены не только фенотипические, но и генетические причины депигментации покрова каракульских овец. Бонитировка молодняка по выраженной пигментации свойств смушка происходит при достижении молодняком полуторалетнего возраста. Именно в этом возрасте пигментация постепенно снижается, и шерсть приобретает полностью белый окрас. Материалы статьи представляют практическую ценность в контроле над биологическим явлением, которое влияет на качество породы каракульской овцы.

Published: September 2023

A multi-objective dynamic demand split delivery emergency material distribution model is developed to enhance the efficiency of emergency material distribution and facilitate the smooth progress of safety rescue operations during unconventional emergencies. This model incorporates the psychological view of those affected by disasters. The issue of dynamic demand may be transformed into a static demand problem by dividing the distribution time window into time domains of equal length. The optimization process is thereafter executed in real-time with the timed batch methodology. A refined ant colony method has been developed to address the model by integrating the attributes of the mathematical model, followed by doing an arithmetic case analysis. The findings indicate that the algorithm and mathematical model suggested in this study are efficacious in addressing the emergency material distribution issue, offering valuable decision-making advice and reference.

Published: September 2023

Buscando contribuir para a geração de informações sobre as curvas de absorção de nutrientes em missioneira-gigante, foi realizado um experimento em delineamento completamente casualizado com três repetições, em uma área de pastagem já estabelecida há dois anos. Foram avaliadas as curvas de acúmulo de macro (N, P, K, Ca, Mg), de micronutrientes (Fe, Mn, Cu. Zn e B) e de massa seca, a partir de cortes realizados aos 7, 14, 21 e 28 dias pós pastejo. Houve aumento linear das concentrações de N e K nas plantas de missioneira-gigante durante o outono, mas esse efeito não foi observado no verão. Os teores de P, Ca e Mg se mantiveram estáveis na planta nos dois períodos, e a concentração de micronutrientes apresentou tendência de redução em ambos, em especial de Fe. O acúmulo de massa seca até os 28 dias de crescimento da missioneira-gigante foi maior no período de outono do que no de verão.

Published: September 2023

Feijoa sellowiana O. Berg é uma frutífera nativa de grande potencial de cultivo, porém no Brasil existem poucos pomares em escala comercial. Uma das dificuldades à expansão da produção está vinculada a obtenção de mudas clonais pela escassez de protocolos eficientes para a propagação vegetativa. Assim, o presente estudo teve como objetivo avaliar a eficiência do antioxidante polivinilpirrolidona (PVP) na estaquia de F. sellowiana. Para isso foram testadas diferentes concentrações de PVP (0, 2000 e 4000mg L-1) aplicados de forma sistêmica, em imersão e associado à solução de ácido indolbutírico (AIB). A aplicação de 4000mg L-1 de PVP na forma sistêmica resultou nas maiores porcentagens de sobrevivência e brotação (47,1 e 25,0%, respectivamente), bem como foi maximizou a formação de calos (50,0%) aos 90 dias e de raízes (47,5%) aos 120 dias de cultivo. O uso de antioxidante polivinilpirrolidona favorece a propagação vegetativa de F. sellowiana por estaquia, podendo apresentar-se como relevante ferramenta na propagação clonal da espécie.

Published: September 2023

The objective of this work is to create a system for separating types of pieces for didactic purposes. An artificial vision system applied to a manipulator was used to perform this task of classifying and separating the pieces, through the use of digital image processing. The vision system uses a camera attached to the robot's end-effector, whose objective is to identify the area, perimeter and position of the centroid of the pieces to be separated. The separation of objects is performed between two classes: with round and non-round shapes. The tests were carried out with objects such as screws and nuts. After obtaining the positions of the objects to be separated by the vision system, some characteristics of these related to the reference system of the robot base are determined. Some difficulties were observed in the recognition of objects related to the colours and lighting conditions of the separation environment. To reduce these problems, black colour objects were used in order to reduce the reflectance. Another problem encountered in the separation process is related to the relative position of objects. In this case, two or more objects can be identified as a single object, depending on their relative positions. The system classifies with a rate of hits greater than 95%.
Maximizing the Runs Scored by a Team in Cricket using Genetic Algorithm
Authors: Krishnamohan Theviyanthan
Published: September 2023

Batting teams get two resources in cricket to score runs with, viz. wickets and balls. Trying to score as many runs as possible off every ball a team faces risks losing wickets. Trying to preserve wickets comes at the cost of not enough runs being scored. Thus, to maximize the runs scored, teams need to make efficient use of the balls and wickets available to them. To that end, teams primarily employ two types of batsmen-aggressive batsmen who try to score as many runs as possible off the balls they face and defensive batsmen who try to protect their wickets. Having too many aggressive batsmen helps a team score more runs off the balls they face but it stands the risk of a team losing all its wickets before they face all of their allotted balls. Having too many defensive batsmen helps a team face all the balls allotted to them but they may not end up scoring enough runs. Hence, selecting the right combination of defensive and aggressive batsmen is essential to maximize the runs a batting team scores. However, this is a computationally complex problem to solve. This study proposes the use of genetic algorithm to optimize the batting lineup of a team to help it maximize the runs scored in an innings. The test results indicate, by using the genetic algorithm, the number of runs scored batting first by the full member teams in the last five years can be improved by 5.46% on average.

Hepatitis C is a health problem in penitentiaries and its elimination must be strengthened. The study describes socio-epidemiological aspects of a hepatitis C investigation in a penitentiary in the region of Triângulo Mineiro in Minas Gerais. It is a cross-sectional and epidemiological survey, with an exploratory, observational, quantitative element. It was carried out in a state penitentiary with 1564 inmates. A semi-structured individual interview and anti-HCV testing were carried out between December 2019 and March 2020, in a simple random sample of 240 prisoners.

Poultry farming is one of the most profitable areas in Brazil, with chicken meat being one of the most important in the world. Brazil is among the main exporters and producers of chicken meat and expanding in the egg market. The Federal District (DF) has been part of this market for years, being this the exploration that most contributes to the Gross Domestic Product of the federation unit. The beginning of poultry farming in the DF took place in the mid-1960s and 1970s, with the integration system that derived from the pioneering expansion in the Brazilian Midwest region. The DF currently has a housing capacity of approximately 20 million birds in 196 poultry establishments, most of which are broilers. The present work brings together information on the poultry scenario in Brazil and in the Federal District, with a literature review to build an overview based on current federal and district regulations and on the main aspects of the National Poultry Health Program.

Los tejidos bucales se encuentran expuestos a una gran variedad de elementos agresores, cuyo tratamiento odontológico implica la rehabilitación que incluye la confección de prótesis dentales. En caso de ausencias dentarias la mucosa bucal no está preparada para recibir prótesis dentales, la agresión mecánica produce acciones irritantes que conduce a la aparición de lesiones inflamatorias, donde la Candida una levadura de la microbiota habitual, puede causar estomatitis subprotésica (ESP). La medicina convencional sintética, ha sido la terapia común para el tratamiento de la estomatitis, sin embargo, dentro de las terapias alternativas naturales la miel de bórax es la fórmula oficinal antigua más utilizada, a pesar de no contar con estudios de concentración inhibitoria mínima (CIM) disponibles. El objetivo fue establecer la CIM de la miel y el borato sobre especies de C. albicans. En el siguiente trabajo se desarrolló una investigación de alcance explicativo, de diseño experimental puro. Se evaluó de manera preliminar la actividad inhibitoria de la miel y el borato al 5%,10%y 15%, utilizando la nistatina como control positivo. Posteriormente se determinó la CIM del borato y, por último, se elaboró una miel de bórax con la CIM obtenida. En los resultados la miel de abeja no presentó actividad sobre los aislados de Candida evaluados, se determinó una CIM para bórax de 256 µg/mL, excepto para los aislados C1 y C6 que presentaron colonias resistentes y para la nistatina la CIM fue 8 µg/mL. La miel de bórax preparada mantuvo las propiedades antifúngicas sobre las aislados de C. albicans evaluados. Se demostró que el efecto inhibidor del borato es similar a la nistatina y que las propiedades antifúngicas de la miel de bórax experimental se mantienen.

La fisiopatología, complicaciones y manifestaciones bucales de la enfermedad de Parkinson debe ser entendida por los odontólogos al momento de instaurar un plan de tratamiento dental; sin embargo, la Facultad de Odontología de la Universidad de Carabobo, carece de la orientación adecuada para el abordaje clínico de estos pacientes. El objetivo del estudio fue proponer un manual didáctico en la atención odontológica de pacientes con esta enfermedad para capacitar a los estudiantes de la Clínica Integral del Adulto I de la Facultad de Odontología de la Universidad de Carabobo. El objetivo fue realizar un proyecto factible, no experimental y transversal. La población de estudio fueron 109 estudiantes del período lectivo 2021 cursantes de la materia, y la muestra fue de 40 estudiantes, representando 15% de la población. Se diseño un cuestionario de 20 preguntas con opciones dicotómicas, previamente validado por expertos y sometido a prueba piloto para calcular el coeficiente de confiabilidad, siendo 0.81 de alta confiabilidad. Los resultados revelaron que, 60% manifiesta no conocer al menos una causa de la enfermedad, 85% expresan no conocer cómo identificar en qué grado del Parkinson se encuentra el paciente, 98% niegan conocer la clasificación de esta según los síntomas que presenta, 62% manifestaron no conocer alguna otra característica de los pacientes con la enfermedad además del temblor en reposo. Los resultados avalaron la necesidad de realizar un manual didáctico para la capacitación de los estudiantes en la atención odontológica de pacientes con enfermedad de Parkinson.
Restauraciones de resinas compuestas reforzadas con fibra. una elección biomimética.
Authors: Calatrava Luis
Published: September 2023

La restauración ideal de los dientes con lesiones del sector posterior, con resinas compuertas, ha sido amplia y controversial en la literatura. Factor esencial es lograr la estabilización de la integridad de la restauración dental, aumento de la cantidad de superficies adecuadas para la adhesión, evitar el riesgo de una falla biomecánica y, por lo tanto, lograr éxito a largo plazo. Sin embargo, algunas de las limitaciones de su función, como la contracción por polimerización bajo tensión y la microfiltración resultante, siguen siendo una preocupación importante. Además, la baja capacidad de carga dificulta su uso en restauraciones grandes que soportan estrés; por lo tanto, se deduce que existe una necesidad considerable de mejorar las propiedades mecánicas, conservando al mismo tiempo las propiedades estéticas. El objetivo de esta revisión narrativa es presentar una descripción general y brindar una comprensión detallada de un nuevo material recientemente recomendado para restaurar grandes cavidades bajo el enfoque biomimético: resinas compuestas reforzadas con fibras, como reemplazo de dentina, que tienen el potencial de mejorar sus propiedades mecánicas, sin afectar el grado de conversión.
ECMI Minorities Blog. Indigenous languages and psychological well-being: Comparing educational, healthcare and employment opportunities in Greenland, Sápmi, and Scotland
Authors: Duncan Seira
Published: September 2023

The past several years have seen increased documentation of the association between indigenous language utilisation and psychological well-being. Scotland is the northernmost non-Arctic country and has been fostering ties with its northern counterparts in recent years; like Greenland and Sápmi, it has indigenous languages. This post compares educational, healthcare, and employment opportunities in these regions and analyses the wider psychological implications of indigenous language utilisation in these sectors. While there appears to be room for improvement in all sectors in the three regions, Greenland, Sápmi, and Scotland will likely benefit from strengthening cross-regional dialogues.

Objectives: To assess functional disability and associated factors in older patients cared for at a large Brazilian urban area. Methods: This is a cross-sectional study performed at a primary health care unit in the city of São Paulo, Brazil. Participants were selected via probabilistic sampling of 400 older individuals. We used a sociodemographic and health questionnaire along with instruments for assessing fear of falling (FES-I), cognitive function (MMSE), and depression symptoms (GDS-15). For dependent variables, we used instruments for assessing basic activities (BADL; Katz) and instrumental activities of daily living (IADL; Lawton). Factors associated with functional disability were analyzed via logistic regression models. Results: The mean age of participants was 75.23 (SD = 8.53); 63.20% were female, 27.00% were dependent in BADL and 39.25%, in IADL. Older individuals with better cognitive function and who had not been hospitalized in the previous year were less prone to functional disabilities. Factors such as older age, more depression symptoms, and greater fear of falling were more linked to disabilities in BADL. Factors such as older age, female sex, and greater fear of falling were more linked to disabilities in IADL. Conclusions: The prevalence of disability in BADL and IADL in the studied sample was high. Modifiable and non-modifiable factors were associated with functional disability. These results may help primary health care professionals understand the risk factors for functional disability in the older population.

Objective: To investigate changes in the frailty levels of older adults in a context of high social vulnerability. Methods: We conducted a prospective cohort study. Data were collected from 2 surveys conducted in 2015 and 2018. The frailty phenotype and sociodemographic and health characterization instruments were used. Descriptive statistical analysis was performed, including non-parametric tests, test for equality of proportions, and multivariate multinomial logistic regression. The use of the database was authorized, and the research was approved by the Ethics Committee. Results: In 2015, 346 community-dwelling older adults participated in the study. After 36 months, a final sample of 223 participants was obtained. In 2015, the prevalence of non-frail, pre-frail, and frail older adults was 13.0%, 56.5%, and 30.5%, respectively. In 2018, 22.9% were non-frail, 56.0% were pre-frail, and 21.1% were frail. Higher education and better quality of life reduced the likelihood of becoming pre-frail and frail, respectively. Conclusion: There was a change in the pattern of frailty among socially vulnerable older adults over a 36-month period.
Information and Theoretical Foundations for Control of the State of Agrocenoses in Real Time
Authors: Mikhailenko Ilya Mikhailovich , Timoshin Valeriy Nikolaevich
Published: September 2023

Objective: Presentation of a complete theory of management of the state of agrocenoses, including sowing crops and weeds. This theory makes it possible to obtain a given crop yield with the required reliability. Such management is formed on the basis of estimates of the parameters of the state of crops, soil environment and weeds, formed according to the data of Earth remote sensing in real time. Methods: The presented theory is based on new mathematical models of the parameters of the state of agricultural crops, soil environment, weeds, as well as models of the relationship of these parameters with remote sensing (RS) data. Control factors in agricultural technology are doses of mineral fertilizers, herbicides and irrigation rates. Therefore, the parameters of the state in the management system under consideration, in addition to the parameters of the biomass of agricultural crops and weeds, are the chemical parameters of the soil environment. All technological operations are carried out at the onset of certain phenological phases of the development of crop sowing. RS data are entered precisely at such moments of time when the parameters of the state of crops and weeds are estimated on their basis. The presented theory is based on classical control principles used in modern dynamic systems. The most important feature of the proposed approach to solving the problem of agrocenoses management is the development of the principle of spatial distribution of agricultural technology parameters. It consists in using models with spatial variables, which are complemented by models of spatial approximation of controls in the form of multidimensional power polynomials. The parameters of the approximation models are evaluated according to the optimal parameters of technological operations obtained on 15-20 test sites of the field. Results: In accordance with the proposed theory, mathematical models of agrocenoses, a real-time control algorithm using RS data and a specialized software package were developed, with the help of which the control system was tested on the example of spring wheat sowing. Conclusion: As a result of testing a specialized software package for the implementation of the proposed theory, the operability of the proposed theory of agrocenoses control in real time and the possibility of using it in practical systems for automated control of agricultural technologies were established.

Parenting is the interaction process between parents and early childhood to instill and develop early childhood’s characters through natural since early age. The present study aims to analyze parenting styles applied by the parents to develop the early childhood’s independent character. In addition, this study employed a case study at which the reseachers gathered the data through observation and interview towards 13 early childhoods and 13 mother (parents) as the respondents. The results of the study revealed that 61,54% of the respondents apply positive parenting style to develop their early childhood’s independent character, 23,08% of the respondents apply permissive parenting style to develop their early childhood’s independent character, and 15,38% of the respondents apply mixed parenting style (positive and permissive parenting styles) to develop their early childhood’s independent character. Thus, the majority of the respondents apply positive parenting style to develop the early childhood’s independent character at home. In conclusion, the 3 parenting styles can be collaborated each other by the parents based on the characteristics of the early childhood, the tasks given, and also the situation.
Sovereign Mercy: The Legalization of the White Russian Refugees and the Politics of Immigration Relief
Authors: Kang S. Deborah
Published: September 2023

At the height of the Great Depression, the Immigration and Naturalization Service (INS) legalized nearly two thousand undocumented Russian immigrants under the Act of June 8, 1934. Based on a random sample of their two thousand case files, “Sovereign Mercy: The Legalization of the White Russian Refugees and the Politics of Immigration Relief” narrates a forgotten moment in the history of undocumented immigration, immigration legalization, and refugee law and policy in the United States. The article specifically argues that even though these Russians were defined as refugees under international law and perceived as such by the public, their American defenders deliberately recast them as undocumented immigrants to halt their deportations to the Soviet Union and give them a pathway to citizenship. This history of the Russian refugees illuminates the conditions under which various forms of immigration relief, such as legalization and the grant of refugee status, emerged in American immigration law. As such, it fills a major gap in the scholarly literature that, to date, has provided few accounts of the history of immigration relief.
