Published: March 2022

Pasar modal dapat diartikan sebagai pasar yang menyediakan berbagai instrumen surat berharga yang diterbitkan pemerintah, maupun pihak swasta. Instrumen pasar modal seperti saham, obligasi jangka panjang, dan dana reksa mampu mejadi pilihan investasi yang dapat memberikan potensi imbal balik (capital gain) di masa depan. Berdasarkan Survei OJK pada 2019, indeks literasi keuangan dan inklusi keuangan masyarakat pedesaan berada di angka 34,53 persen dan 68,49 persen. Dari data tersebut, terbukti bahwa wawasan, kesadaran, ketertarikan masyarakat pedesaan Indonesia terhadap literasi dan inklusi keuangan seperti pasar modal masih terbatas. Kegiatan ini bertujuan meningkatkan dasar ilmu, kesadaran, dan ketertarikan masyarakat pedesaan terhadap pasar modal kepada masyarakat di Desa Lobang, Kecamatan Limpung, Kabupaten Batang. Kegiatan telah direalisasikan pada 2020. Metode yang digunakan adalah pendekatan aksi berupa sosialisasi mengenai pentingnya investasi, dan edukasi teoritis pasar modal, serta analisa kondisi pasar modal. Edukasi literasi pasar modal meliputi dasar teori dan analisis pasar modal. Hasil kegiatan menunjukan bahwa, kebanyakan masyarakat Desa Lobang mengalami peningkatan dari tidak tahu menjadi tahu tentang pasar modal. Diharapkan kedepannya, masyarakat Desa Lobang yang sudah mengikuti kegiatan ini tertarik untuk mulai melakukan investasi di pasar modal.

A capital market can be interpreted as a market that provides various instruments of securities issued by the government, as well as private parties. Capital market instruments such as stocks, long-term bonds, and Danareksa can be an investment options that can provide potential capital gains in the future. Based on the OJK Survey in 2019, the index of financial literacy and financial inclusion of rural communities was at 34.53 per cent and 68.49 per cent. From the data, it is proven that the insight, awareness, interest of rural Indonesian people towards financial literacy and inclusion such as capital markets is still limited. This activity aims to increase the basis of knowledge, awareness, and interest of rural communities in the capital market to the community in Lobang Village, Limpung Subdistrict, Batang Regency. Activities have been realized in 2020. The method used is an active approach in the form of socialization about the importance of investment, and theoretical education of capital markets, as well as analysis of capital market conditions. Capital market literacy education includes the basis of capital market theory and analysis. The results of the activity showed that most lobang villagers experienced an increase from not knowing to know about the capital market. It is expected that in the future, the people of Lobang Village who have participated in this activity are interested in starting to make investments in the capital market.
NMR spectroscopy of live human asthenozoospermic and normozoospermic sperm metabolism
Authors: Reynolds Steven , Calvert Sarah J , Walters Stephen J , Paley Martyn N , Pacey Allan A
Published: March 2022

Sperm motility varies between ejaculates from different men and from individual men. We studied normozoospermic and asthenozoospermic ejaculates after density-gradient centrifugation washing (DCG, 80/40%) and compared high- (80%) and low (40%)-motility sperm populations within the same sample. Our objective was to identify differences in endogenous metabolomes and energy metabolism in relation to sperm motility. 1H-Nuclear Magnetic Resonance spectroscopy (NMR) measured the endogenous metabolome of live human sperm. Incubating sperm with 13C-labelled substrates detected energy metabolism by 13C-NMR. The study examined 850 ejaculates and diagnosed asthenozoospermia in 6.1%. DGC was used to wash 160 normozoospermic (N) and 52 asthenozoospermic (A) ejaculates to recover high-motility sperm from the pellet (80N/80A) and low motility from the interface (40N/40A). 1H-NMR spectra, 45(N) and 15(A), were binned and the integrals normalised by sperm concentration. Sperm from 126(N) and 36(A) ejaculates were incubated with either 13C-glucose, 13C-fructose or 13C-pyruvate. 13C-NMR lactate and bicarbonate integrals were normalised by motile or vital sperm concentrations. 1H-NMR spectra choline integrals from the 80A population were significantly lower than the 80N, P  < 0.0001. 13C-substrate conversion to lactate was significantly higher for 40A sperm than 80A sperm when normalised by motile sperm concentration. Bicarbonate integrals were sporadically observed. Sperm from asthenozoospermic ejaculates had similar glycolytic requirements to normozoospermic ones, with larger differences observed between 40 and 80% sperm populations. Higher lactate levels produced by 40% sperm may indicate that impaired sperm motility is due to dysregulated energy metabolism. The alteration in choline metabolism provides opportunities to understand the aetiology of asthenozoospermia.

Lay summary

How well sperm swim (motility) varies between ejaculates from different men? Normal sperm motility is beneficial to conception and some men diagnosed with infertility have low sperm motility. Sperm metabolise molecules to produce the energy required for motility. We measured concentrations of molecules within sperm and metabolism of molecules given to sperm and related these to the proportion of motile sperm. The study examined 850 sperm samples and found low motility in 6.1%. Metabolism of molecules given to sperm was similar between low and normal motility sperm samples. However, when the most motile sperm were separated from the rest, they were more efficient in metabolising these molecules to achieve motility. Lower concentrations of a molecule called choline were found in low-motility sperm samples compared to normal samples. Choline is associated with cell membranes, energy metabolism and oxidative stress, which may give opportunities to understand the causes of low motility.

Randentropy: A Software to Measure Inequality in Random Systems
Authors: D’Amico Guglielmo , Scocchera Stefania , Storchi Loriano
Published: March 2022

The software Randentropy is designed to estimate inequality in a random system where several individuals interact moving among many communities and producing dependent random quantities of an attribute. The overall inequality is assessed by computing the Random Theil’s Entropy. Firstly, the software estimates a piecewise homogeneous Markov chain by identifying the change-points and the relative transition probability matrices. Secondly, it estimates the multivariate distribution function of the attribute using a copula function approach and finally, through a Monte Carlo algorithm, evaluates the expected value of the Random Theil’s Entropy. Possible applications are discussed as related to the fields of finance and human mobility.
FEATURES OF THE FORMATION OF MULTI-CHANNEL PULSE CURRENTS AND FAST-MIGRATING ELECTRIC SPARKS IN THE LAYER OF CURRENT-CONDUCTING GRANULES OF ELECTRIC-DISCHARGE INSTALLATIONS

Published: March 2022

The paper reveals the electro-physical features of the formation of multi-channel pulse currents and fast-migrating electric sparks in the layer of current-conductive granules of electric-discharge installations (EDIs) with reservoir capacitors. Such features make it possible to increase many times the productivity of the electric-spark dispersion of metal granules during single discharge current of reservoir capacitors, which flows between the electrodes of EDIs. Theoretical substantiation and experimental confirmation of multi-channel spark discharges in the layer of conductive granules are presented. The influence of the capacitance and charge voltage of reservoir capacitors on the nature of transient processes in the discharge circuit of the EDIs is investigated. The dependence of the effective value of the active load resistance of the EDIs on the value of the pre-charge voltage of its reservoir capacitors and the value of its capacitances has been experimentally determined. It is proved that an increase in the averaged Q-factor of the discharge circuit with an increase in the charge voltage of the capacitor bank of EDI is caused by a decrease in the effective value of the active resistance of the layer of metal granules when spark-generating discharge currents flow through it.

Published: March 2022

OBJECTIVES

Survivors of the PICU face long-term morbidities across health domains. In this study, we detail active PICU follow-up programs (PFUPs) and identify perceptions and barriers about development and maintenance of PFUPs.

METHODS

A web link to an adaptive survey was distributed through organizational listservs. Descriptive statistics characterized the sample and details of existing PFUPs. Likert responses regarding benefits and barriers were summarized.

RESULTS

One hundred eleven respondents represented 60 institutions located in the United States (n = 55), Canada (n = 3), Australia (n = 1), and the United Kingdom (n = 1). Details for 17 active programs were provided. Five programs included broad PICU populations, while the majority were neurocritical care (53%) focused. Despite strong agreement on the need to assess and treat morbidity across multiple health domains, 29% were physician only programs, and considerable variation existed in services provided by programs across settings. More than 80% of all respondents agreed PFUPs provide direct benefits and are essential to advancing knowledge on long-term PICU outcomes. Respondents identified “lack of support” as the most important barrier, particularly funding for providers and staff, and lack of clinical space, though successful programs overcome this challenge using a variety of funding resources.

CONCLUSIONS

Few systematic multidisciplinary PFUPs exist despite strong agreement about importance of this care and direct benefit to patients and families. We recommend stakeholders use our description of successful programs as a framework to develop multidisciplinary models to elevate continuity across inpatient and outpatient settings, improve patient care, and foster collaboration to advance knowledge.
The Impact of Frailty and Comorbidities on Heart Failure Outcomes
Authors: Salmon Thomas , Essa Hani , Tajik Behnam , Isanejad Masoud , Akpan Asangaedem , Sankaranarayanan Rajiv
Published: March 2022

Frailty is a multisystemic process leading to reduction of physiological reserve and a reduction in physical activity. Heart failure (HF) is recognised as a global cause of morbidity and mortality, increasing in prevalence over recent decades. Because of shared phenotypes and comorbidities, there is significant overlap and a bidirectional relationship, with frail patients being at increased risk of developing HF and vice versa. Despite this, frailty is not routinely assessed in patients with HF. Identification of these patients to direct multidisciplinary care is key, and the development of a frailty assessment tool validated in a large HF population is also an unmet need that would be of considerable benefit in directing multidisciplinary-team management. Non-pharmacological treatment should be included, as exercise and physical rehabilitation programmes offer dual benefit in frail HF patients, by treating both conditions simultaneously. The evidence for nutritional supplementation is mixed, but there is evidence that a personalised approach to nutritional support in frail HF patients can improve outcomes.

Zur Geschichte der ungarischen Rezeption Albrecht von Hallers •
Authors: Latzkovits Miklós
Published: March 2022

Der Aufsatz beschäftigt sich mit der Rezeptionsgeschichte der Gedichte Albrecht von Hallers im Ungarn des 18. Jahrhunderts. Als Grundlage für die Untersuchung dienen die Haller-Zitate in zeitgenössischen Stammbucheinträgen. Mit dieser Frage setzten sich zwar sowohl deutsche als auch ungarische Forscher schon früher auseinander, jedoch, wie im vorliegenden Aufsatz behauptet wird, unter Anwendung einer gewissermaßen falschen Methode. Es wurde nämlich in diesen früheren Arbeiten nicht näher darauf eingegangen, ob das Zitat gegebenenfalls einer sekundären Quelle entnommen wurde. Dieser Ansatz führte jedoch zu falschen Schlussfolgerungen. Vorliegender Aufsatz versucht, die aus sekundären Quellen stammenden Zitate von jenen aus dem „Original“ zu unterscheiden. Es wird festgestellt, dass die in Stammbucheinträgen im 18. Jahrhundert zu lesenden Haller-Zitate überwiegend aus nachweislich sekundären Quellen herzuleiten sind. Je „berühmter“ ein Autor war – diesen Eindruck gewinnt man anhand des Korpus –, umso mehr zitieren ihn die Zeitgenossen aus indirekten Quellen.

A experimentação é parte fundamental nos processos de ensino-aprendizagem relacionados ao ensino de Física e representa um grande desafio, particularmente, para o ensino de Física Moderna e Contemporânea. Neste trabalho, apresentamos um produto educacional baseado na tecnologia da videoanálise enquanto estratégia para levar à sala de aula o experimento de difração de elétrons. Trata-se de iniciativa concreta de utilizar o programa Tracker para permitir a estudantes e professores a visualização de um fenômeno fundamental da Física, concebido teoricamente pelo físico francês de Broglie e reportado experimentalmente no começo do século XX por Davisson, nos Estados Unidos, e Thomson, no Reino Unido, os três agraciados com o prêmio Nobel. O material didático é associado à comprovação do comportamento ondulatório dos elétrons, com implicações para explorar o conceito de dualidade onda-partícula, fundamental para a Mecânica Quântica. Ocorre que os custos para realização desse experimento são muito elevados, de modo que a videoanálise foi utilizada para produzir um material acessível, versátil e com o condão de dar a professores e estudantes a possibilidade de realizarem a atividade em diversos contextos, configurando um exemplo objetivo de utilização de uma Tecnologia de Informação e Comunicação, no caso, a videoanálise com o Tracker, no Ensino de Física Moderna e Contemporânea fomentar atividades investigativas e de experimentação.

Published: March 2022

Regional universities are the mainstay of national education, its impact at the local level is multidimensional and consists in the implementation of research projects, research and development, enhancing of integrative relations between economic entities of the region, formation of competitive highly qualified employees in accordance with the requirements of the labor market and global challenges of standardization. This process is impossible without attribution of the entrepreneurial universities format, focused on consolidation of the interaction between universities, government and business in matters related to the provision of educational services, as well as in the aspect of generating fundamental knowledge and innovations in the interests of the sectoral and regional economy. The establishment of regional universities as entrepreneurial ones is associated with a number of financial problems, the solution of which is impossible without the participation of the state. The institutional reform proposed today reveals the existing problems and does not completely solve the problem of the development of regional entrepreneurial universities. The expanding interinstitutional relations of the education system determine a new qualitative understanding of the essence of higher education as a sphere of the economy.

Published: March 2022

The purpose of the article is to assess the use of consumer lending tools in the context of COVID-19 restrictions and predict the development directions of digital credit innovations in the consumer segment. It has been established that digital innovation in consumer lending is proceeding at a high rate, digital ecosystems, platforms and services are being formed. The qualitative side of the changes is characterized by the creation of new and modernization of traditional lending instruments produced by traditional banks and non-banking organizations. The COVID-19 pandemic has accelerated the scaling of digital technologies in lending. It was revealed that the following became widespread in the Russian market: payment by instalments, card lending, annuity target and non-target loans. Analysis of the dynamics of the consumer lending market showed that: the POS lending market in Russia is stagnating; the most popular way of consumer lending is by instalments; credit cards with instalment options are not widespread; the most innovative products are instalment plans secured by funds in electronic wallets. The development of two promising consumer lending instruments is predicted: the provision of instalments through marketplaces and digital ecosystems, which have the greatest potential for consumer lending and stimulating retail sales; card consumer lending, characterized by the replacement of the material form of instruments with virtual cards in the context of the COVID-19 pandemic.
Prospects for the Development of the Gold Market in the Information Economy
Authors:   Volgograd State University, Manakhov Boris
Published: March 2022

The subject of this study is to identify the role of demonetized gold in the information economy, including stressful development during periods of instability, crises, sanctions and pandemic. The author identified trends in the dynamics of gold prices over the past five years, its demand by investors and industry, policies of central banks and developed countries. The significance, reasons and consequences of the refusal to prolong the cartel agreement of the central banks on the control of the price of gold (CBGA) are determined. The article identifies exclusively geopolitical (not financial and economic) risks that underlie a sharp and radical change in the structure of Russian gold and foreign exchange reserves and the refusal to place the National Wealth Fund assets in dollars. The prospects for gold that are opening up in this connection have been identified. The reasons for the sharp decrease in the intensity of the replenishment of Russian gold and foreign exchange reserves with gold until its virtually complete cessation have been identified. A critical analysis of the allegedly “new” functions of gold in the information economy is given, it is shown that in reality it is only a transformation (adaptation) of traditional functions. The inevitability of expanding the circulation and use of digital currency in the information economy is shown, which will require improving the institutional framework, since a virtual asset, including potentially based on gold, is converted into Russian rubles upon payment, which, in accordance with the law, is used to pay.

Published: March 2022

Today, tourism is one of the fastest growing industries in the structure of the world economy. Every year Russia’s share in the global tourism industry is growing, which is reflected in the economy and infrastructure of the country as a whole. The majority of Russian tour agents value the development of regional tourism, which has become a stimulus for the development of tourism in the constituent entities. In the conditions of the modern socio-economic space, the sphere of tourism and recreation can be of strategic importance for the development of regions, especially those that belong to the category of subsidized or even depressed. In this regard, a detailed study of the tourist and recreational potential of the regions is of particular importance.

Published: March 2022

Resumo Evitar sobrepreços e preços manifestamente inexequíveis são dois objetivos principais da recém-promulgada Lei nº 14.133, de 1º de abril de 2021. O presente artigo demonstra que, ao tentar alcançar o primeiro objetivo, a nova lei de licitações promove o segundo, pois um comando específico tende a reduzir os preços até congelá-los nos menores valores possíveis, conduzindo os contratados à maldição do vencedor. Alerta-se os agentes públicos sobre o fato de que a manutenção desse comando levará a descumprimentos generalizados de contratos e a uma eventual falência de competidores. O método Monte Carlo é utilizado para demonstrar que um mecanismo abrangente de pesquisa de preços evitará o problema e garantirá o efeito pretendido pela lei.

Resumo Objetivo analisar a associação da cor da pele/raça autorreferida com indicadores biopsicossociais de idosos. Método estudo transversal conduzido com 941 idosos de uma comunidade na microrregião de saúde no Brasil. Os dados foram coletados no domicílio e com instrumentos validados no país. Procedeu-se à análise descritiva e regressão logística binária, multinomial e linear (p<0,05). Resultados a autodeclaração de cor/raça branca predominou entre os idosos (63,8%). A cor/raça preta foi fator de proteção para a autoavaliação da saúde péssima/má (OR=0,40) e regular (OR=0,44) e para o indicativo de sintomas depressivos (OR=0,43); e associou-se ao maior escore de apoio social (β=3,60) e ao menor número de morbidades (β=-0,78). Conclusão os achados denotam que, independentemente de características sociodemográficas e econômicas, os idosos da cor/raça preta apresentaram os melhores desfechos dos indicadores biopsicossociais.

ABSTRACT Objective Food and nutritional evaluation of children can support public policies to combat early overweight and obesity. This study developed and validated a quantitative food frequency questionnaire for assessing the dietary intake of children. Methods This is a cross-sectional study of the development of a food frequency questionnaire for 130 children of both genders aged 7 to 10 years old. For the food frequency questionnaire list, 81 food items were selected. The validity of the food frequency questionnaire was evaluated by comparison with 24-hour recalls and reproducibility was performed by comparing two food frequency questionnaires. Results Most of the foods with 95% relative contribution were ultra-processed, such as packaged snacks and powdered juice. In validation, correlation coefficients were found between 0.45 (p<0.000) for lipids and 0.37 (p<0.000) for carbohydrates. An adjustment for energy reduced the correlations, but there was an increase in the correlation in calcium (r=0.75) and retinol (r=0.20). In terms of reproducibility, all macronutrients and calcium showed a satisfactory intraclass correlation coefficient (>0.400) and moderate correlations [proteins (0.54; p<0.000) and lipids (0.41; p<0.000)]. Conclusion The food frequency questionnaire developed was valid and able to assess the local food consumption by children from northeastern Brazil.
Profiling the consumer of agroecological products using cluster analysis
Authors: Araújo Heliene Macedo de , Marjotta-Maistro Marta Cristina
Published: March 2022

Abstract In a context of searching for economic sustainability and health-promoting practices, agroecology presents itself as a point of integration of several knowledges: traditional, scientific, productive technical and economic-social. Moreover, in order to truly achieve sustainable agriculture, all aspects of food production, distribution and consumption need to be integrated, and consumers’ choices can be considered as an impact factor on the environment. This article aims to characterize consumers in three agroecological markets in the municipalities of Belo Horizonte, Santana do Riacho and Jaboticatubas, in Minas Gerais. A primary data survey was used, with 191 questionnaires applied in three agroecological neighborhood markets. The statistical analysis used was cluster analysis; 2 clusters were identified: a) “Consumers Closer to Agroecological Knowledge”; and b) “Sustainable Consumers and Less Close to Agroecological Knowledge”. These analyses allowed to identify the real perceptions of consumers regarding agroecological markets and to define assertively the limitations of the locations, in addition to showing which strategies are the most appropriate to simultaneously meet the needs of consumers and stimulate the sale of products, thus ensuring the financial viability of farmers.

Authors: Santos Tatiana Tomal Brondani dos , Torres Ricardo Lobato
Published: March 2022

Resumo A garantia da Segurança Alimentar e Nutricional (SAN) e do Direito Humano à Alimentação e Nutrição Adequadas (DHANA) à população depende da produção sustentável de alimentos diversificados e saudáveis. A agricultura familiar é o segmento responsável por grande parte dos alimentos destinados ao consumo interno. Políticas públicas como o Programa de Aquisição de Alimentos (PAA) e o Programa Nacional de Alimentação Escolar (PNAE), que possibilitam o acesso de agricultores familiares ao mercado institucional e o fornecimento de alimentos a populações em vulnerabilidade, são de grande relevância à promoção da SAN. O objetivo deste artigo foi analisar quais os efeitos do acesso ao mercado institucional brasileiro na SAN de agricultores familiares do município de Almirante Tamandaré. Para tal, adotou-se como procedimentos metodológicos a revisão integrativa da literatura e o estudo de caso. Para a apresentação e análise dos resultados foi utilizada a análise de conteúdo aliada a uma análise estatística descritiva dos dados. Evidenciou-se que o acesso dos agricultores familiares entrevistados ao mercado institucional impactou positivamente nas suas condições de SAN, ao possibilitar geração e melhoria de renda, garantia de trabalho e escoamento de produção, diversificação produtiva e, consequentemente, maior variedade de alimentos consumidos.
A new species of Ancistrus (Siluriformes: Loricariidae) from Tapajós and Xingu basins, Brazil
Authors: Neuhaus Emanuel B. , Britto Marcelo R. , Birindelli José Luís O. , Sousa Leandro M.
Published: March 2022

Abstract A new Ancistrus species is described from Tapajós and Xingu river basins. It is distinguished from its congeners by the singular body color pattern, consisting of dark vermiculated stripes almost all over the body, and also by combination of features as a narrow head, large internostril distance, and absence of rows of enlarged odontodes on the lateral plates. In addition, the new species is distinguished from congeners that inhabit the rio Tapajós basin by the presence of a fully-developed adipose fin (vs. adipose fin absent in Ancistrus parecis and A. tombador, and vestigial adipose fin or absent in A. krenakarore). It differs from A. ranunculus, also from the rio Xingu, by the color pattern, smaller body size, smaller gill opening, and narrower cleithral width. The new taxon adds a new record to the list of species shared among the Xingu and Tapajós basins.

RESUMEN El estudio que se presenta se enmarca en el Proyecto “DREAM”, cuya finalidad ha sido conocer las condiciones de los sistemas educativos de los países participantes respecto a la dimensión afectiva de la educación como eje vertebrador de un Modelo Educativo Afectivo. En este trabajo se presentan los resultados obtenidos en la franja 3-6. Se ha empleado una metodología mixta. En el estudio cuantitativo se ha podido poner de manifiesto que el profesorado participante posee una buena formación previa, con lo cual es comprensible que el modo de comprender y enfocar el currículum el profesorado participante en el estudio cualitativo sea más abierto, que las actividades tengan en cuenta las dos dimensiones, que exista una preocupación por escuchar al alumnado y que exprese las emociones.
EN BUSCA DEL TIEMPO VIVIDO: EDUCACIÓN PARA NARRAR LO HUMANO (LABORATORIO BIOGRÁFICO)
Authors: Gutiérrez Adriana María Ruiz
Published: March 2022

RESUMEN Los sujetos están constituidos por las condiciones que, durante su existencia, los afirman y los desposeen. De ahí la dependencia y la responsabilidad ante nuestra vida social compartida, cuyas fallas exponen, drásticamente, a ciertas poblaciones a la violencia y las demás formas de desposesión. Reconocer esta vulnerabilidad implica, además de comprender lo humano y lo inhumano, recrear otras realidades posibles. Bajo este marco, la educación se constituye en una experiencia narrativa que permite comprender los acontecimientos pasados, las prácticas del presente y las transformaciones del futuro, a través de los relatos de aquellas “vidas negadas”. Esta composición presenta, así, los fundamentos y los hallazgos de un laboratorio biográfico-narrativo con enfoque en vulnerabilidad.
