Authors: Silva Jéssica Hellen Souza da , Rezende Mayara de Azeredo
Published: June 2023

A espécie vegetal Schinus terebinthifolius Raddi é nativa do Brasil e, popularmente, quase toda parte da planta é utilizada para fins medicinais, incluindo o fruto, conhecido como “pimenta rosa”. Neste sentido, estudos que apontem ao desenvolvimento de inovação tecnológica associada à produção e uso de S. terebinthifolius para saúde são importantes. O objetivo desse estudo foi realizar uma prospecção de produtos para saúde a base de S. terebinthifolius Raddi e/ou de pimenta rosa, através de pesquisa na literatura e buscas em bancos de dados de patentes. Os resultados revelaram propostas de formulações farmacêuticas à base de S. terebinthifolius e seus frutos para uso em saúde humana. Os pedidos de patentes demonstraram que são inúmeras as utilidades da espécie S. terebinthifolius dentro do contexto de formulação de produtos para saúde humana a nível mundial, mas que no contexto brasileiro, não há investimento em inovação tecnológica associada à produção e uso de S. terebinthifolius. Esta pesquisa propõe a pimenta rosa como um candidato a mais para a produção de insumos farmacêuticos através da Pesquisa e Desenvolvimento de novos produtos fitoterápicos inovadores, estimulando o parque tecnológico brasileiro e a cadeia de inovação em medicamentos da biodiversidade.

Authors: Mashabai Ismi , Irahayu Asran Andi Mustika
Published: June 2023

Downtime is a condition in which the machine stops operating not on scheduled stops but due to a disturbance that occurs on the machine, so the machine will be idle until the machine has been repaired or is not in a state of disturbance. Downtime is when production equipment is not functioning due to a sudden inspection and repair of damaged equipment. Elevators can raise the material to a height of up to 50 meters; the capacity can reach 50 ????3/hour. The construction can reach a vertical position. The working principle of this tool is to move the material vertically by placing the material in buckets which are linked by a chain or belt at a certain distance which rotates on the pulley so that the bouquet can move vertically. This study uses the tree diagram method to analyse downtime problems by applying the 5 M + 1E technique.

SPHERES OF USE OF REMITTANCES OF INTERNATIONAL LABOR MIGRANTS
Authors:   Taras Shevchenko National University of Kyiv, Shepel Oleksandra
Published: June 2023

Remittances of international labor migrants are of critical importance for poorer countries – both in terms of the longterm survival of households and the adequate functioning of these states in terms of macroeconomic stability, the ability to provide basic state services, and the ability to finance socio-economic development in priority directions for these states and societies. At the same time remittances from international labor migrants are, by their economic essence, primarily a transfer, and not extra resources. That is why this phenomenon should be considered not only in the plane of monetary and fiscal policy of governments, but also in terms of the social policy complex of the labor donor country. This is in line with the significant social role of remittances from international labor migrants – primarily for households and local communities, especially in depressed regions and rural areas. The peculiarities of the use of remittances of international labor migrants are reflected in the structure of their households' expenses in the donor countries. The expenses of this group of economic agents are divided into two large groups: 1. current consumption and 2. savings and investments, which reflect the main components of the GDP of the labor donor country and are key drivers of the socio-economic growth of the state. International labor migrants form informed, based on their own perspective and previous experience, micro-level decisions on the use of remittances earned abroad, based on the short- and long-term needs of their household, as well as the household's future plans in combination with a set of macro-environmental limiting factors in the country of origin. All this in a complex affects the tendency of international labor migrants to the frequency and methods of transferring earned funds to the donor country, the specific areas of use of this transfer by households whose members are employed abroad, as well as the nature of the state policy of labor donor countries, which are aimed at the maximum involvement of this resource in one's own national economy and its adequate use within the framework of stimulating socio-economic development in the short- and long-term time horizons.

USE OF ECONOMIC ANALYTICS METHODS TO ENSURE THE ECONOMIC SECURITY OF SOCIO-ECONOMIC SYSTEMS
Authors:   Dnipropetrovsk State University of Internal Affairs, Kononova Iryna
Published: June 2023

The article carried out research on the definition of approaches to the category of "economic security" of socio-economic systems, and proposed a proper definition of the concept of "economic security". The role and significance of economic analytics in the system of ensuring economic security of socio-economic systems is determined, the methods and methods of economic analytics used to ensure economic security are investigated. Analytics is a field of human activity that is carried out with the aim of conducting an analysis of the state of the object and the state of its development, which will allow making appropriate decisions regarding this object. Many academics consider analytics today as the art of analysis. Modern socio-economic transformations that are taking place in the economy, in the country as a whole, which are caused by the scientific and technical revolution, as well as the increase in the importance of information and information resources in economic processes. It was these conditions of informatization of society that caused the formation of the knowledge economy and the emergence of a new paradigm of economic analytics. Economic analytics is one of the most promising areas of modern economic science, which is based on the methods of economic analysis through the use of information resources, computer methods, etc. The development of economic analytics as a science is conditioned by the development of economic theory and the formation of economic hypotheses, theories and concepts on this basis. In the process of evolution of these theories and concepts, the methodological toolkit of modern economic analytics was formed. The formation of analytical support for economic security is connected with the development of related fields of knowledge, such as mathematics, statistics, accounting and others. The study of the main methods of economic analysis to ensure the economic security of socio-economic systems allows us to come to the conclusion that each of the methods we have considered has certain limitations in use, and therefore does not provide an opportunity to fully determine the existing state of economic security. Quantitative and qualitative methods of determining the level of economic security have become the most widespread. Qualitative analysis of the state of economic security of the socio-economic system precedes quantitative analysis, consists in determining all negative factors and risks of the external and internal environment, forecasting the negative consequences that they may cause, as well as developing measures to neutralize and minimize these risks. Quantitative analysis is also necessary for a full characterization of the state of economic security, so a comprehensive approach must be used for a full analysis of the state of economic security

The article considers issues related to the analysis of approaches to assessing the creditworthiness of bank borrowers. The article analyses various views of scientists and allocates main components of the concept of "creditworthiness", which comprehensively reveal the content of the concept and its main characteristics, both in relation to individuals and legal entities. The article offers a structure of assessment of creditworthiness of clients on the basis of the world and domestic practice, which includes two components: criteria of creditworthiness of a client and methods of assessment of creditworthiness of a client. Based on a comparative analysis of the main 10 foreign models for assessing the creditworthiness of borrowers, it is concluded that the indicators of "borrower's reputation" and "ability to repay the loan" are present in a larger number of models. The article considers foreign and domestic methods of assessing the borrower's creditworthiness and concludes that they have both common and distinctive features, but there is no single ideal method among them that would be suitable for a larger number of banking institutions. It is shown that there is a need to select instruments that will reflect the risks of potential losses. By determining the optimal system for assessing the borrower's creditworthiness, the bank reduces the risks of loan default and, in the future, bankruptcy of the institution. It is determined that the methods used in the practice of domestic banks generally assess financial indicators, but there is a gap in the use of qualitative characteristics in assessing the borrower's activities that do not have a quantitative expression, which are considered in detail in foreign methods for assessing the creditworthiness of a supplier. To make such an assessment, banking institutions need to pay attention to the analysis of the external environment, which will help in determining credit risks. It is the combination of qualitative and quantitative indicators that will help banks conduct a comprehensive multifactorial analysis and minimise credit risk. Therefore, based on the recommendations of the National Bank of Ukraine, each banking institution should choose an acceptable methodology or system for analysing and assessing creditworthiness in order to ensure the correctness of this assessment. It is concluded that there is currently no single methodology for assessing the creditworthiness of borrowers.
CURRENT IMPERATIVES OF GLOBALIZATION OF THE LABOR MARKET: FORMS AND STRUCTURE
Authors:   Kyiv National Economic University named after Vadym Hetman, Konokhov Serhiy
Published: June 2023

The development of the world labor market at the current stage of world economic progress is characterized by the systemic influence on its structural dynamics of a number of global imperatives, which manifests itself at the levels of demographic, transnational, scientific and technical, regional integration, and institutional and regulatory factors. Their synergistic effect leads to the transformation of the world labor market into an open competitive system of a global type, the quantitative and qualitative parameters of which are determined, on the one hand, by the complex action of the mechanisms of the objective economic laws of value, the capitalist population, demand and supply of labor, concentration of production, competition; and from the second – the specifics of the expanded reproduction of labor resources within the framework of national economies and at the international level. The purpose of the article is to characterize the structure-forming imperatives of globalization of the labor market. The modern economic nature of the structure-forming imperatives of the globalization of the labor market actualizes an important methodological issue regarding the comprehensive renewal of the theoretical foundations of its research at the level of the operation of economic laws and the influence of emergent factors. global economic transformations and the deep organic connection of the labor market with structural changes in the international economic system and all forms of international economic relations. The development of the global format of the functioning of the labor market is the result of the convergence of cultural traditions, moral values of different peoples and nations, their psychological and socio-cultural characteristics, attitudes to work and learning, the degree of self-education, discipline and responsibility, which, "integrating" into global institutions, acquire qualitatively new features. So, we can conclude that together they ensure the effective functioning of operational and functional business models of international companies and firms and are a powerful driver of modernization of the institutional, organizational, economic and technological basis of the world economy on the platform of global business networks.
Racionalidad de mercado versus racionalidad ecológica: Una crítica al mal llamado “pensamiento único” en economía y ciencias sociales
Authors:   Universidad de Guadalajara, Sandoval Cabrera Pablo
Published: June 2023

Desde sus orígenes la economía ortodoxa (o lo que Marx llamó economía “vulgar”) se ha esgrimido como una disciplina infalible y de validez universal. Al margen del con- texto social, se asume que en todas las sociedades los individuos (agentes económicos) son perfectamente racionales, por lo que sus decisiones de consumo o producción son siempre y en todo lugar, inequívocamente maximizadoras. Dichas decisiones condu- cen a una asignación “eficiente” de los recursos a través del mecanismo de mercado, dando forma colectivamente a una especie de racionalidad de mercado. Sin embargo, hay otras racionalidades a partir de las cuales las sociedades construyen visiones del mundo distintas, presentando comportamientos que no responden a los principios establecidos por el utilitarismo individualista que pregona la economía convencional. Los saberes dominantes desvinculados han demostrado su incapacidad para dar respuesta a los grandes retos que enfrenta la sociedad moderna, entre otros los rela- cionados con la pobreza que agobia a tres cuartas partes de la población mundial, el hambre, la exclusión social, la ascendencia del crimen, el cambio climático y la pérdi- da, al parecer irrefrenable, de recursos bióticos. Ante esta reconocida incapacidad se demanda la integración de saberes alter- nativos, hasta ahora segregados por el pensamiento occidental y la llamada raciona- lidad instrumental-utilitarista, para dar lugar a nuevas visiones, con mayor capacidad explicativa, más incluyentes y diversos. De la alternancia epistémica resurge el saber ambiental o racionalidad ambiental que se funda en valores que ponen en el centro del análisis al ser humano en su integralidad, en su diversidad y diferencias. Bajo este marco de análisis, el objetivo de este trabajo de reflexión consiste en confrontar ambos tipos de racionalidad a partir del análisis de los principios y cosmo- visiones que le dan estructura y sentido a cada una de ellas.

Griffon Vultures restrict movements around roosts and supplementary feeding stations, even when carrion is available on the field: a call for wind energy zonation to avoid ecological traps on Mediterranean islands
Authors: Cerri Jacopo , Fozzi Ilaria , De Rosa Davide , Aresu Mauro , Apollonio Marco , Berlinguer Fiammetta
Published: June 2023

Wind energy is developing on Mediterranean islands, where endangered populations of Griffon Vulture (Gyps fulvus) occur. As griffons are subjected to collisions with wind turbines while foraging, it is necessary to understand which factors affect their movements, to minimize the potential impact of wind farms.We assessed habitat use by 37 griffons (n. GPS locations = 130,218) and its overlap with wind farms in Sardinia (Italy), an island where griffon vulture population is increasing thanks to concrete conservation actions and wind energy is significantly expanding.Griffons in Sardinia cover smaller areas (95% isopleth = 956.3 ± 677.7 km2, 50% isopleth = 73.8 ± 48.2 km2) than in mainland Europe, restricting most of their movements within 5-10 km from colonies and roosts.Concentrated movements aligned with the fact that around roosts and colonies, approx. 20 tons of carrion (21% of estimated available carrion) are provided each year in supplementary feeding stations, while griffons still have enough cliffs to breed. Therefore, our results are highly suggestive that resource availability can constrain griffon movements on Mediterranean islands.Overall, 6 wind farms out of 29 were built in areas that were covered by moving griffons. Two of them were positioned right outside the areas the most used as foraging grounds, around roosts and supplementary feeding stations.As griffon movements concentrate around nesting/roosting sites and feeding stations, wind farms should not be built in a buffer zone around these highly utilized areas, and mitigation measures, including the removal of livestock carrion, should be adopted for those that are built at greater distances. There is also an urgent need for updated data about wind energy development. The creation of supplementary feeding stations could be used to shape the enlargement of the foraging grounds of an increasing Griffon Vulture population on Mediterranean islands and to mitigate wind farms impacts.
Hypotheses on the extended phenotype of the mitochondrion: sex, mortality, and aging
Authors: Irlam Gordon
Published: June 2023

How did sex evolve, how is sex evolutionary stable, why do eukaryotes appear mortal, and why do eukaryotes age, are all pressing questions. This paper presents a mitochondrial perspective on the evolution of the eukaryotic cell that appears capable of answering these questions. Rather than viewing a mitochondrion as a passive entity taken up by an archaeal host that remains in the driving seat, mitochondria are viewed as the key force driving eukaryogenesis. The proto-mitochondrion is presumed to have manipulated its archaeal host to engage in sex in order to replicate itself in a more and more beneficial environment. This process is hypothesized to still be operating today as a result of the mitochondrion's continued production of reactive oxygen species (ROS). The specific production of ROS by the mitochondrion appears to be an intentional mechanism to cause the organism to age, and ultimately to die. Faced with mortality, if the organism wishes to pass on its nuclear genes it will typically engage in sex as a means of resetting age. Eukaryotic species that instead reproduced parthenogenetically would find themselves out-competed by sexual species due to the reassortment of genes that comes with sex. The mitochondrial genome benefits via kin selection from the death of its host as a result of an increased ability to adapt to a changing environment that comes from a shortened time between successive sexual generations. The resulting model appears capable of explaining the seeming intentionality of many age-related diseases, and provides a high level theoretical framework for better understanding them.

Authors: Silva Wallace Marcelino da , Machado Carlos José Saldanha , Vilani Rodrigo Machado
Published: June 2023

O artigo tem por objetivo estabelecer as relações entre a História Ambiental e a sua dinâmica com o Capitaloceno e o Antropoceno, destacando sua importância para análises de questões ambientais atuais. A questão ambiental tem sido revisitada a partir de conceitos como Capitaloceno e Antropoceno. Uma análise comparada desses conceitos por meio da perspectiva da História Ambiental pode contribuir para construir visões mais integradas dentro das relações Sociedade/Natureza. Foi realizada uma revisão integrativa da literatura, publicada entre 2016 e 2021, que abordasse temas e análises dentro do campo de conhecimento da História Ambiental assim como os conceitos de Capitaloceno e Antropoceno. Os resultados demonstram que os estudos da História Ambiental vêm crescendo junto aos trabalhos sobre as diversas visões do Antropoceno. Por outro lado, há uma escassez de trabalhos na área do Capitaloceno. Conclui-se que a História Ambiental com suas análises de longa duração constitui um campo de conhecimento com contribuições específicas para as reflexões críticas e para a politização da questão ambiental. A contribuição da pesquisa está na construção de elementos para uma análise crítica do conceito de Antropoceno, a partir da História Ambiental, e no fortalecimento das discussões quanto às diferenças, forças e formas de relação entre sociedade e natureza trazidas pelo Capitaloceno.
Conservation and Conflict in the Cockpit Country, Jamaica, 1962-2022.
Authors: Altink Henrice
Published: June 2023

Cockpit Country in west central Jamaica is a unique karst landscape. Based on a wide range of published and online sources, this article examines threats to the area’s biodiversity and attempts to conserve it, from Jamaica’s independence in 1962 to the declaration of the Cockpit Country Protected Area in 2022. It focusses on several stakeholders – the government, international organisations, environmental groups, and Cockpit communities –, and argues that their interplay made conservation of the area a far from straightforward trajectory.  It will show that by the late 1980s, international organisations increasingly used mainstream conservation approaches in their work to protect the Cockpit Country and that local environmental groups gradually also came to embrace mainstream conservation. But it will also highlight that Cockpit communities have had a more ambivalent attitude towards conservation of the area than local environmental groups and international organisations, and that a focus on short-term gain has made the government a reluctant and even obstructive stakeholder in the preservation of the area’s biodiversity.
Debates en Torno a la Crisis Ambiental y al Neoextractivismo Agrícola. Historia y Posibles Alternativas de las Tensiones en los Paisajes Intermedios en el Gran Rosario (Argentina)
Authors: Galimberti Cecilia , Ciarniello Laura
Published: June 2023

En el marco actual de los debates en torno a los impactos ambientales producidos por el modelo neoextractivista agrícola, este trabajo aborda una breve síntesis sobre la historia de los reclamos y denuncias con relación a los efectos producidos por este modelo, así como también, sus propuestas alternativas y el rol que ha adquirido la agroecología, en especial, en los espacios de interfaz entre el suelo urbano y el rural. Se considera así a la agroecología como una alternativa que parte del reconocimiento complejo del ecosistema y contribuye al cuidado del ambiente y a los actores sociales que forman parte. En este sentido, se toma como caso de estudio al Gran Rosario en Argentina, dado su importante rol como productor y agroexportador de soja a nivel mundial. A través de una metodología mixta cuali-cuantitativa se aborda la historia de la transformación agraria de dicha región, focalizando en el estudio de los conflictos y tensiones ambientales existentes en los paisajes intermedios del Gran Rosario, así como el desarrollo de algunas propuestas alternativas basadas en la agroecología. Se considera que estas pequeñas experiencias resultan de contribución al conocimiento y desarrollo de alternativas posibles, desde un abordaje integrado, articulando distintos actores y saberes diversos que posibilitan una nueva relación entre sociedad y naturaleza.

Mahasiswa kedokteran dikenal sebagai mahasiswa dengan tuntutan pendidikan yang berat. Sebagai syarat kelulusan, mahasiswa memiliki kewajiban untuk menyelesaikan tugas akhir yaitu skripsi. Banyak mahasiswa yang mendapati kesulitan dalam pengerjaan skripsi yang kemudian berkembang menjadi perasaan negatif dan menimbulkan masalah seperti cemas. Strategi koping sangat berperan bagaimana mengendalikan cemas tersebut. Adapun salah satu kecerdasan yang mampu memberikan pengaruh untuk respons perilaku ketika berhadapan pada permasalahan yang menimbulkan cemas adalah adversity quotient (AQ). Tingkat AQ yang lebih tinggi, mengakibatkan tingkat cemas yang individu alami lebih rendah. Tujuan dari penelitian ini adalah menganalisis hubungan AQ dengan tingkat cemas pada mahasiswa bimbingan skripsi FK Unimus. Penelitian ini termasuk observasional analitik, pendenkatan corss sectional. Populasi yang ditentukan berupa mahasiswa bimbingan skripsi FK Unimus angkatan 2019 yang diambil melalui total sampling berjumlah 128. Analisis data mempergunakan uji korelasi rank spearman, signifikan jika p<0,05. Hasil uji korelasi rank spearman memperlihatkan p-value = 0,000 (p < 0,05) serta memiliki koefisien relasi (r) yaitu r = - 0,612. Terdapat hubungan kuat antara AQ dengan tingkat cemas pada mahasiswa bimbingan skripsi FK Unimus angkatan 2019 dengan arah korelasi negatif, semakin tinggi AQ maka semakin rendah tingkat cemas yang dialami.
