Authors: Сафонова Е.Л.
Published: May 2024

Рецензия на книгу «Леонид Коган. Письма» основана на изучении русскоязычных пуб­ликаций, посвященных великому скрипачу. В создании ле­топи­си его жизни и творчества главная роль принад­лежит Е. Г. Гилельс, В. Ю. Григорьеву, Н. Л. Коган, а среди опубликованных источников особо значимо его немногочисленное, но ценное литературное насле­дие, раскрывающее неделимость граней чело­веческой и артистической личности Л. Б. Когана. Включение в новую книгу цитат из статей и интервью Л. Когана, а также из воспоминаний о нем обогаща­ет эпистолярий и помогает читателю увидеть в зеркале писем многогранный и живой портрет Леонида Борисовича. Переписка Л. Когана открывает, наряду с новыми фактами его деятельности, профессиональные, интеллектуальные, психологические черты многих известных музыкантов и деятелей искусства, менеджеров, ученых, высокопоставленных особ. Она наполнена высказываниями различных стилей и форматов, при этом возможно введение части корпуса писем в научный обиход.

A review of the book “Leonid Kogan. Letters” is based on the study of Russian-language publications dedicated to the great violinist. In creating his life and work chronicle, the leading role belongs to E. G. Gilels, V. Yu. Grigoriev, N. L. Kogan, and among the published sources, his small but valuable literary heritage is especially significant, revealing the indivisibility of the facets of human and artistic personality. The addition in the new book of quotations from articles and interviews with L. Kogan and from memoirs about him enriches the epistolary genre, helping the reader to see a multifaceted and live portrait of Leonid Borisovich in the mirror of letters. L. Kogan’s correspondence reveals, along with new facts about his activities, the professional, intellectual, and psycho­logical traits of many famous musicians and artists, managers, scientists, and high-ranking persons. It is replete with different styles of statements and formats and at the same time, it is possible to introduce part of the corpus of letters into scientific use.
His Majesty―Concert Poster

Published: May 2024

В статье «У рояля то же, что было и раньше», опубликованной в журнале «Музыкальная академия» № 2 за 2023 год, профессор Высшей школы музыки имени Х. Эйслера в Берлине пианист-аккомпаниатор Семён Скигин обратился к своим молодым коллегам, делясь профессиональным опытом, накоп­ленным самостоятельно и «подсмотренным» у других. Настоящее эссе, в центре внимания которого искусство составления концертных программ, является продолжением той публикации. Автор подробно рассказывает, как яркое, броское анонсирование концерта зачастую обеспечивает не только его хорошую «продажу», но и успех у публики.

In the article “At the piano it’s the same as before,” published in the “Music Academy” (no. 2, 2023), professor at the Hochschule für Musik Eisler in Berlin, pianist-accompanist Semyon Skigin addressed his young colleagues, sharing professional experience accumulated independently and “seen” from others. This essay, which focuses on the art of compiling concert programs, is a continuation of that publication. Often, a bright, catchy announcement is an important part of not only a good “sale” of a concert but also success with the public.

Published: May 2024

O presente trabalho tem como objetivo analisar as dinâmicas do desenvolvimento regional da Amazônia Legal (AL) e o seu processo de produção do espaço agrário. Verificou-se que o processo de desenvolvimento proposto para a região se deu na esteira da implantação de políticas de desenvolvimentistas a partir do meado do século XX. O objetivo das políticas visou a integração da AL com as demais regiões do país, a ocupação do “vazio” demográfico, incentivos fiscais para a entrada de grupos econômicos para explorar a região economicamente e a diminuição das desigualdades regionais. Nesse sentido o estudo busca fazer uma análise histórica dos Planos Nacionais de Desenvolvimento, da Política Nacional de Desenvolvimento Regional e seus desdobramentos para reorganização do espaço agrário dessa região. Esse estudo está alicerçado numa abordagem crítica de cunho qualitativo, que através de uma análise exploratória e descritiva buscou em fontes bibliográficas, bem como em documentos oficiais a sustentação teórica e os dados necessários para a construção desse artigo. Como resultado a ser melhor detalhado no desenvolvimento deste trabalho, é possível afirmar que o processo de integração nacional para o desenvolvimento econômico da AL se constituiu em detrimento da exploração dos recursos naturais e espoliação social. Acrescenta ainda o fato de que mesmo o Estado tendo criado um esforço para desenvolver as políticas para o desenvolvimento da AL, elas foram insuficientes para sanar o vazio demográfico, a desigualdade regional, os problemas agrários e ambientais nessa região.

Authors: Sofiana Mega Sari Juane , Safitri Ikha , Nurhidayanti
Published: May 2024

Pemangkat is a coastal area in Sambas Regency which has a mangrove ecosystem. One of the biota found in mangrove forest areas is the Giant Mudskipper. This fish is often used as an environmental bioindicator due to its characteristics of living in the intertidal zone and being able to absorb and accumulate metals. Heavy metal pollution in marine and coastal areas has become a global problem that causes negative impacts on ecosystems, biota, and human health. One of the heavy metals that can pollute waters due to fishing and port activities is lead (Pb). Pemangkat is one of the centers of capture fisheries activities in West Kalimantan. Therefore, this research aims to analyze the content of the heavy metal of Pb in water, sediment, and Mudskipper in the Pemangkat mangrove ecosystem, Sambas, West Kalimantan. The Pb content in water, sediment, and Giant mud skipper samples was analyzed using an Atomic Absorption Spectrophotometer (AAS) at a wavelength of 283.3 nm. Accumulation of heavy metal in the biota was determined by the bioconcentration factor (BCF). The concentration of lead metal (Pb) in water and sediment samples was highest at Station II, such as 0.40 mg/L and 0.25 mg/L respectively. The metal content of Pb in Giant Mudskipper was highest at Station I (0.224 mg/kg). The BCF values for Giant Mudskipper at Stations I and II were 1.18 and 0.86.

Authors: Abbas Wandi , Ismira Andi , Losi Zainuddin
Published: May 2024

The dynamics of social life in Indonesia are increasingly developing along with developments in the order of life which have a direct impact on relations between communities and the relationship between society and government. The development of information technology and the unavoidable level of globalization are accelerating the pace of change in social movements, which were previously just ordinary movements, into organized social movements in the economic, political, social, and religious fields. This research uses qualitative methods that focus on in-depth interviews and library research as support. The birth of social movements is the impact of democratic principles which provide space and opportunities for people to fight for constitutional rights. The development of information technology on social movements needs to receive government attention, even though social movements are part of the principles of constitutional democracy. It is feared that social movements that are not paid attention to by the government in the current era of globalization will be influenced by radicalism which threatens the stability of the government, including in West Sulawesi Province, which is not impossible if social movements in the form of radicalism movements also develop rapidly. Using the soul approach will certainly be a way to suppress the actions of radicalism movements in West Sulawesi

Published: May 2024

The stunting rate in Maluku has increased from 2016 to 2018. This prompted the local government to issue a handling policy. The consequence is the budget allocation to accelerate the reduction of stunting rates. However, appropriate strategies are also needed to achieve this goal so that the existing budget is used effectively and efficiently. This study first aims to analyze the level of expenditure variance, expenditure growth, expenditure effectiveness and efficiency. Second, to describe the progress of stunting handling and recommend priority strategies in the prevention. This research uses a mixed-method approach with a type of concurrent triangulation design. Quantitative data is obtained from financial reports and questionnaires, while qualitative data is obtained through interviews, documents and field notes during the study. After the data was collected, variance, growth, effectiveness and efficiency of expenditure and strategy analysis were conducted. The results showed that the budget for handling stunting in the health Office fluctuates yearly but tends to decrease. The variance of expenditure is classified as good, as well as the effectiveness of expenditure is still quite good. Expenditures for handling stunting are also very efficient, which reduces the stunting rate. This can be seen in the stunting rate 2019 of 30.38 to 26.10 in 2022.
