Published: May 2021

La presente investigación aplicado los criterios e indicadores de sostenibilidad de la metodología “Marco para la Evaluación de Sistemas de Manejo de Recursos Naturales incorporando Indicadores de Sostenibilidad (MESMIS)” en el análisis de dos sistemas de producción comercial de caprinos en el municipio de Ocaña. Evaluando el cumplimiento de las dimensiones económica, ambiental y social. Los indicadores, se unificaron y ponderaron participativamente con los productores. La valoración de los indicadores permitió observar el estado actual de la sostenibilidad, mostrando buen nivel de cumplimento en las tres dimensiones. Igualmente, se revelan puntos a mejorar en la dimensión económica, en donde la carencia de registros contables y financieros no permite la determinación real de los costos de producción. Por otro lado, la falta de registros sanitarios para comercialización, impiden la incursión en nuevos mercados, limitando las potencialidades genéticas y de transformación de productos.

NATURAL SCIENCE AND TECHNOLOGY EDUCATION: IMPORTANCE OF VALUES
Authors: Lamanauskas Vincentas
Published: May 2021

In recent years, both in Lithuania and in other countries, natural science and technology development is given emphasis to. Decreasing youth interest in natural sciences and/or technology has become a big concern. On the one hand, such concern is reasonable, because youth motivation choosing the studies at universities is usually directed to social and humanitarian sciences. Such a situation is determined by a number of reasons. Anyway the choice of a further way is closely connected with the values of the younger generation. Progress in science and technology is very high. Progress in the sphere of formation of values of society sharply lags behind. So, value component of natural science and technology education should become a priority in all education system, at all its levels. Values should be systematically inoculated, directing young people to become mature personalities. This means the ability to apply the acquired knowledge and abilities practically, to solve everyday life problems, to educate self-confidence, feel responsibility and be able to adapt to the changing environment and seek to save the environment, suitable for the man’s existence. Values are formed not adapting to the situation “here and now”, but orienting to future perspective “there and then”. Value component of natural science and technology education should occupy a proper place in educational practice, and should be more exhaustively examined in a scientific sense. Key words: science education, technoogy education, values formation.

Published: May 2021

One of the main natural science education aims is the integral perception of the phenomena occurring in nature. Therefore, teachers have to be able to find and convey the pupils the links between separate natural sciences. For this, it is necessary to specially organise the teaching process itself, to prepare the teaching material. First of all, the material has to be distinguished which reflects interdisciplinary links, to choose the teaching forms, methods and ways. In the renewed natural science general programme, seeking to bring secondary education nearer to present day requirements and to improve pupils’ learning motivation, one of the most rapidly spreading science fields in the world – nanotechnology – is included. To what extent and how deep to analyse nanotechnologies, decides the teacher himself. Therefore, it is necessary for the teacher to be prepared to work in the constantly changing teaching environment, to be able to realise the newest interdisciplinary didactic principles, to use information communication technologies. By giving a sample lesson, natural science (physics, chemistry, biology) informatics and mathematics subject relation realisation didactic possibilities are revealed in the article. A sample scenario of the lesson Nanotechnologies: we produce a fullerene model, is presented. The lesson course is described, the tasks, integrating natural sciences, information technologies and mathematics are presented, extra tasks and the tasks for homework are foreseen.

Authors: Oparaugo Buike
Published: May 2021

Public relations is a strategic approach towards the creation of goodwill and brand image through developing a cordial relationship between the organization and its target audience. Image is the reputation or perception of a person, group or corporate body, held by others, often as a result of what they (the corporate body) do or have done. The study is set to find out two major things: To find out if public relations plays a role in image building of an organization; and to determine if public relations plays a role in image sustenance of an organization. The methodology for the paper is the review of existing literatures in the field of public relations and image building and sustenance. Public relations is a veritable tool of corporate image building and sustenance as it helps shape the way publics of an organization see or perceive the organization. These publics can be internal or external. By internal we mean employees, and by external we mean customers/clients and the host community. In building or sustaining a corporate image of an organization by the Public Relations Officer (PRO), there are quite a number of tools very important. These tools include press/news release, press/news conference, sponsorships, house organs, Annual General Meeting (AGM), etc. Different types of public relations are presented.
Serum soluble transferrin receptor levels are
independently associated with homeostasis model
assessment of insulin resistance in adolescent girls
Authors: Klisic Aleksandra , Kavaric Nebojsa , Kotur Jelena , Ninic Ana
Published: May 2021

Introduction

Markers of iron homeostasis are related to insulin resistance
(IR) in adults. However, studies in children and adolescents are scarce and
show contradictory results. The aim was to evaluate the potential relationship between iron status markers and IR. Additionally, no previous study has
explored the mutual effect of biomarkers of iron homeostasis and inflammation (i.e. high sensitivity C-reactive protein (hsCRP)), and adipokines (i.e.
retinol-binding protein 4 (RBP4)) on IR in the cohort of adolescent girls.

Material and methods

A total of 60 girls age between 16 and 19 years were
included in the study. Serum levels of ferritin, transferrin, soluble transferrin
receptor (sTfR), hsCRP, and RBP4 were measured by immunonephelometry.
Homeostasis model assessment of insulin resistance (HOMA-IR) and iron
homeostasis indexes were calculated. Univariate and multivariate binary logistic regression analysis were used to investigate the possible independent
associations of the examined biomarkers. Principal component analysis was
used to examine their mutual effect on HOMA-IR in the studied girls.

Results

Ferritin, sTfR, hsCRP and RBP4 were significant predictors for higher HOMA-IR in univariate analysis (p = 0.020, p = 0.009, p = 0.007, p =
0.003, respectively). Multivariate regression analysis after adjustment for
waist circumference (WC) showed that serum sTfR levels remained positively associated with higher HOMA-IR (p = 0.044). Factorial analysis revealed
that the obesity-inflammation related factor (i.e., WC and hsCRP) and adipokine-acute phase protein related factor (i.e., RBP4 and ferritin) showed
significant differences between HOMA-IR < 2.5 and HOMA-IR ≥ 2.5.

Conclusions

Serum sTfR levels are independently associated with HOMA-IR,
whereas higher serum ferritin levels together with higher RBP4 are related
to higher HOMA-IR in adolescent girls.
Lógica Formal versus Lógica Transcendental: sobre um capítulo da polêmica entre a filosofia analítica e o movimento neokantiano em torno ao logicismo
Authors: Amaral Lucas Alessandro Duarte
Published: May 2021

O objetivo deste artigo é dar foco a um capítulo específico dentro do amplo contexto de debate entre o movimento neokantiano com a filosofia analítica. Trata-se da discussão entre Ernst Cassirer e Bertrand Russell, que toma lugar na história da filosofia nas décadas finais do século dezenove e iniciais do vinte. Em específico, veremos as posições de cada um dos autores em questão no que se refere a natureza da lógica e ao programa logicista. Para tanto, num primeiro momento, reconstruiremos essa discussão partindo de Russell. Daí, apresentaremos a posição dos neokantianos (com maior ênfase em Cassirer) nessa narrativa. Feito isso, trataremos da crítica do filósofo inglês a noção de “lógica transcendental” e suas implicações na filosofia de Cassirer, bem como a de seus predecessores na escola de Marburgo. Depois traremos ao debate a reposta do neokantiano ao filósofo inglês; para, por fim, tratarmos de alguns aspectos do logicismo defendido por Cassirer.

Authors: Васюра С.А.
Published: May 2021

Проблема коммуникативной активности человека становится чрезвычайно актуальной в связи с трансформацией прежних констант общения в современных условиях меняющегося мира; возникает потребность в создании психологического инструментария для изучения этой активности. В статье представлены результаты авторской разработки методики изучения направленности коммуникативной активности, ее теоретический и психометрический анализ. Теоретической предпосылкой создания методики изучения направленности коммуникативной активности является концептуальное представление о функциях человека как субъекта общения (В.Н. Панферов). Исходными теоретическими положениями послужили также идеи активности человека, заложенные в концепции интегральной индивидуальности (В.С. Мерлин); полифонии активности в концепции метаиндивидуального мира (Л.Я. Дорфман); интегративный подход к коммуникативной активности (С.А. Васюра). Методика выявляеткоммуникативную, информационную, когнитивную, эмотивную, конативную, креативную направленность активности человека, реализующуюся в непосредственном и Интернет-общении. На выборке 418 человек 17 - 25 лет (128 юношей, 290 девушек) обсуждены результаты валидизации методики. Доказано, что методика обладает прогностической ценностью при изучении круга явлений, относящихся к непосредственному и опосредованному (виртуальному) общению, а также к коммуникативному потенциалу личности. Методика изучения направленности коммуникативной активности может применяться в научных и прикладных исследованиях.

The problem of a person's communicative activity becomes urgent due to the transformation of previous communication constants in the current conditions of the changing world, there is a need for development of psychological tools for this activity. The article contains results of developing methodology of investigation of оrientation on communicative activity, its theoretical and psychometric analysis. The theoretical premise of the methodology is the conceptual idea of human's functions as a subject of communication (V.N. Panferov). The ideas of human's activity that is a part of integrated individuality concept (V.S. Merlin), polyphony of activity in the concept of metainividual world (L.Ya. Dorfman), integrative approach to communicative activity (S.A. Vasyura) have become the underlying theory. The methodology examines communicative, informational, cognitive, emotive, conative, creative оrientation on a person's activity that implements in the direct Internet-communication. Results of methodology's validation are discussed on a sample of 418 people 17 - 25 aged (128 males, 290 females). The research has a predictive value in examining a range of features referring to both direct and indirect (virtual) communication, as well as a person's communicative potential. This study can be used in scientific and applied researches.

Актуальность статьи обусловлена необходимостью изучения особенностей трудовой мотивации специалистов в социальной сфере. Специалист, обладающий высоким уровнем мотивации, наиболее эффективно и качественно будет реализовывать свою профессиональную деятельность, что в полной мере положительно отразится на деятельности учреждения в целом. Анализ научных источников позволил выделить основные факторы и ресурсы, влияющие на развитие трудовой мотивации специалистов. Изучение опыта практической деятельности учреждений социальной сферы позволило прийти к выводу о том, что в процессе управления организацией руководителями не всегда учитываются индивидуальные мотивы, интересы и потребности сотрудников. В ходе опытно-экспериментальной работы автором были установлены преобладающие мотивы трудовой деятельности специалистов социальной сферы, и показана причинно-следственная связь между наличием трудовой мотивацией сотрудников и эффективностью работы учреждения социальной сферы. Определены наиболее благоприятные условия, влияющие на повышение уровня мотивации сотрудников в профессиональной деятельности. Статья представляет интерес для руководителей учреждений системы социальной защиты, специалистов по социальной работе, исследователей.

Authors: Haladu Dr.Alhassan
Published: May 2021

Due to the greater influence of sustainability issues on today’s global matters, this research observed how social-sustainability could influence the relationship between specific firm characteristics of firm age, audit firm, effective tax rate and environmental-sustainability disclosure. This area is a very wide gap that is yet to be fully explored especially as it affects developing economies. In this study, the researcher covers the entire environmentally sensitive sector of the Nigerian economy with 67 companies chosen as sample size for the study. Measurement of the dependent and moderating variables was done through simple average disclosure index (SADI) which, isthe simple average of the total disclosure made on individual elements under these two observations. The framework and model of the study were built on the moderating effects of social-sustainability on the relationship between specific corporate characteristics and environmental-sustainability reporting. Using Stata13 the study tests for the level of disclosure of environmental-sustainability, types, direction, and impacts of the relationships between the specific corporate characteristics and environment-sustainability reporting; and the significance of the influence of the relationship. The results show among other things that a positive and significant relationship exists between firm age, audit firm & effective tax rate, and environmental-sustainability reporting. Furthermore, it was discovered that high environmentally sensitive elements such as biodiversity & wastes, effluents, product impacts and environmental management department; have lower disclosure rates compared to lower environmental elements like materials used and energy consumed.

Authors: Okey Prof. ONUCHUKU, , Elizabeth Lizzy OBAYORI,
Published: May 2021

The paper examined the impact of fiscal policy on balance of payments in Nigeria. The objectives of the study were to; examine the impact of government capital expenditure, corporate tax and external debt on BOPs. Time series data from 1980 to 2015 was collected from CBN statistical bulletin. The applied the techniques of ADF unit root test, co-integration and vector error correction model. The results of the estimated model showed that all the time series were stationary at order one. Also, the dynamic model depicted by the co-integration result showed that there is a long run equilibrium relationship among the variables. Similarly, the vector error correction result showed that the coefficient of ECM has the hypothesized negative sign and statistically significant at 5% level. The current year’s value of government capital expenditure showed that a percentage increase in government capital expenditure causes a favorable balance in BOPs by 65.5%. Moreover, the current year’s value of corporate tax showed that a percentage increase in corporate tax decreases the balance in BOPs by 164.4%. The estimated VECM result further showed that a percentage increase in government external debt causes an increase in BOPs by 77.1%. From the discussion so far, it is obvious that fiscal policy measures are effective in achieving a favorable balance of payments in Nigeria. Based on these findings, the following recommendations amongst others were made; Expansionary policies on fiscal policy measures especially in government capital spending and corporate tax policy should be encouraged as they play vital role in the growth of industrial production and help to improve the BOPs in Nigeria. Also, government should avoid superfluous and uncreative borrowing that will serve as a leakage to the economy.

REFORMASI, CALVIN, DAN PERJAMUAN KUDUS
Authors: Kristanto Billy
Published: May 2021

Artikel ini mencoba untuk menggambarkan teologi Calvin tentang Perjamuan Kudus sebagai jawaban ekumenis untuk menjembatani polemik antara Luther dan Zwingli dalam komunitas Protestan dengan meninjau pandangan awal dan akhir tulisan Calvin. Saya berargumentasi bahwa pembacaan ekumenis Calvin terhadap kedua reformator telah membantu mentransformasi polemik yang ada menjadi alternatif kreatif. Saya akan membandingkan pemahaman Luther dan Zwingli tentang Perjamuan Kudus. Kemudian, tulisan awal Calvin tentang Perjamuan Kudus akan digambarkan sebagai jalan tengah antara Luther dan Zwingli. Bagian ketiga membahas tulisan Calvin belakangan tentang Perjamuan Kudus, yang akan diikuti oleh tinjauan historis dari beberapa teolog dan juga Konsili Kalsedon. Natur relasi antara tanda dan yang ditunjuk oleh tanda merupakan hal yang kompleks dan multidimensi. Tinjauan historis juga meneguhkan jiwa ekumenis Calvin. Akhirnya disimpulkan bahwa meskipun masih ada perbedaan pandangan, ada kemiripan yang bermanfaat dari berbagai pandangan teologis.

Authors: Gunawan Chandra
Published: May 2021

The notion that "God is light" is essential to the understanding of the literary structure of 1 John because it links units of thought in the Epistle. This central idea and its ethical implications, "living in the light" and "living in love," develop throughout the letter. To understand the function of this concept and to grasp its meaning in 1 John, the present study utilizes discourse analysis to read the document in light of its micro and macro structures. Interpreting the "God is light" teaching in the Epistle-based on its literary structure-will shed some light on understanding the main issue addressed in 1 John.?

Objetivo: Revisar, através da literatura científica, a eficácia, interações farmacológicas e benefícios do uso dos fitoterápicos kava-kava (Piper methysticum L.) e maracujá (Passiflora incarnata L.) como alternativas terapêuticas para o tratamento do Transtorno de Ansiedade Generalizada (TAG), agravados em tempos de pandemia. Métodos: Trata-se de uma revisão bibliográfica sistemática qualitativa, na qual utilizou-se os sites eletrônicos SciELO, PubMed, Google acadêmico, ANVISA e OMS para a busca de dados. Resultados: Observou-se que os principais benefícios da utilização de fitoterápicos diz respeito ao custo reduzido, à facilidade de acesso e ao baixo índice de efeitos colaterais e reações adversas. Encontrou-se um número considerável de informações que demonstraram a utilização e a procura de fitoterápicos à base de P. Incarnata para tratar as psicopatologias como o TAG, durante o isolamento social e a quarentena. Não foram encontrados números significativos de estudos capazes de comprovar a utilização da P. Methysticum durante a pandemia da COVID-19. Considerações finais: Sugere-se que as espécies P. Incarnata e P. Methysticumão eficazes para o tratamento do TAG por possuir alto valor medicinal com propriedades farmacológicas ansiolíticas, anticonvulsivantes e sedativas.
Visualization of radar-observed rainfall for hydrological risk assessment
Authors: Olsson Jonas , Berg Peter , van de Beek Remco
Published: May 2021

Abstract. Short-duration high-intensity rainfall constitutes a major hydro-meteorological hazard, with impacts such as pluvial (urban) flooding and debris flow. There is a great demand in society for improved information on small-scale rainfall extremes, both in real time (e.g. for early warning) and historically (e.g. for post-flood analysis). Observing
this type of events is notoriously difficult, because of their extreme
small-scale space-time variability. However, owing to recent advances in
weather radar technology as well as integration with ground-based sensors,
observational products potentially applicable in this context are now
available. In this paper we present a visualization prototype tailored for
hydrological risk assessment by using sub-basins as spatial units, by
allowing temporal aggregation over different durations (i.e. accumulation
periods) and by expressing high rainfall intensities in terms of return
period exceedance. The radar-based data is evaluated by comparison with
gauge observations and the quality is deemed sufficient for the intended
applications. Different stakeholders have shown great interest in the
prototype, which is openly accessible online.
A new mechanistic understanding of ecophysiological patterns in a widespread alpine dwarf shrub – Refining climate-growth relationships

Abstract. Considering the recent widespread greening associated with dwarf shrubs in arctic and alpine ecosystems, further understanding of how these shrubs respond to environmental conditions is of crucial importance. Here we present novel insights and propose a new method to monitor shrub growth, using high-precision point dendrometers. We analyzed intra- and inter-annual growth patterns of a common evergreen species (Empetrum nigrum ssp. hermaphroditum) by measuring its hourly radial stem variability at a micrometer scale over four successive years on exposed ridge positions and along a steep elevational gradient. With the same temporal resolution, we collected near-ground micro-environmental data and identified environmental drivers controlling growth behaviour. Overall, we found high inter-plant variability in growth-defining parameters, but high similarities in growth responses to the micro-environment. Early-season radial growth in spring exhibited high sensitivity to winter thermal conditions and prolonged ground-freezing in spring, suggesting that the evergreen species E. hermaphroditum remains photosynthetically active during the snow-free period, which increases carbohydrate accumulation for early season physiological activities. We discovered a phase of radial stem shrinkage during the winter months, which can be attributed to an active cell water reduction to protect the plant from frost damage. We present the first fine-scale intra-annual growth curves for an alpine dwarf shrub and identify soil moisture availability and winter freezing conditions as the main drivers of radial stem variability, thus forwarding the ongoing debate on the functional mechanisms of greening and browning in arctic and alpine regions.
Chicxulub museum, geosciences in Mexico, outreach and science communication – built from the crater up

Abstract. The Chicxulub science museum is special, in that it is built around an event
in geological time representing a turning point in the planet's history and
which brings together the Earth system components. Studies on the
Chicxulub impact, mass extinction and Cretaceous–Paleogene boundary provide
an engaging context for effective geoscience communication, outreach and
education. The museum is part of a research complex in Yucatán Science
and Technology Park in Mexico. Natural history museums with research
components allow for the integration of up-to-date advances, expanding their
usefulness and capabilities. The impact ranks among the major single events
shaping Earth's history, triggering global climatic change and wiping out
∼76 % of species. The ∼200 km Chicxulub
crater is the best preserved of three large terrestrial multi-ring impact
structures, being a natural laboratory for investigating impact dynamics,
crater formation and planetary evolution. The initiative builds on the
interest that this geological site has for visitors, scholars and students
by developing wide-reaching projects, a collaboration network and academic
activities. The Chicxulub complex serves as a hub for multi- and
interdisciplinary projects on the Earth and planetary sciences, climate
change and life evolution, fulfilling a recognized task for communication of
geosciences. After decades of studies, the Chicxulub impact remains under
intense scrutiny, and this programme with the core facilities built inside the
crater will be a major player.
Benchmark tests for separating n time components of runoff with one stable isotope tracer
Authors: Hoeg Simon
Published: May 2021

Abstract. A validation of the recently introduced iterative extension of the standard two-component hydrograph separation method is presented. The data for testing this method are retrieved from a random rainfall generator and a rainfall-runoff model composed of linear reservoirs. The results show that it is possible to reconstruct the simulated event water response of a given random model input by applying the iterative separation model and using a single stable isotope tracer. The benchmark model also covers the partially delayed response of event water so that a situation can be simulated in which pre-event water is rapidly mobilized. It is demonstrated how mathematical constraints, such as an ill-conditioned linear equation system, may influence the separation of the event water response. In addition, it is discussed how the volume weighted separated event water response can serve as an estimator for a time-varying backward travel time distribution.
A conceptual model-based sediment connectivity assessment for patchy agricultural catchments

Abstract. The accelerated sediment supply from agricultural soils to riverine and lacustrine environments leads to negative off-site consequences. In particular, the sediment connectivity from agricultural land to surface waters is strongly affected by landscape patchiness and the linear structures that separate field parcels (e.g. roads, tracks, hedges, and grass-buffer-strips). Understanding the feedbacks between these structures and sediment transfer is therefore crucial for minimising off-site erosion impacts. Although soil erosion models can be used to understand lateral sediment transport patterns, model-based connectivity assessments are hindered by the uncertainty in model structures and input data. In particular, the representation of linear landscape features in numerical soil redistribution models is often compromised by the spatial resolution of the input data and the quality of the process descriptions. Here we adapted the WaTEM/SEDEM model using high resolution spatial data (2 m × 2 m) to analyse the sediment connectivity in a very patchy mesoscale catchment (73 km2) of the Swiss Plateau. Specifically, we used a global sensitivity analysis to explore model structural assumptions about how linear landscape features (dis)connect the sediment cascade. Furthermore, we compared model simulations of hillslope sediment yields from five sub-catchments to tributary sediment loads, which were calculated with long-term water discharge and suspended sediment measurements. Our results showed that roads were the main regulators of sediment connectivity in the catchment. In particular, the sensitivity analysis revealed that the assumptions about how the road network (dis)connects the sediment transfer from field-blocks to water courses had a much higher impact on modelled sediment yields than the uncertainty in model parameters. Moreover, model simulations showed a higher agreement with tributary sediment loads when the road network was assumed to directly connect sediments from hillslopes to water courses. Our results ultimately illustrate how a high-density road network combined with an effective drainage system increase sediment connectivity from hillslopes to surface waters in this representative catchment of the Swiss Plateau. This further highlights the importance of considering linear structures in soil erosion and sediment connectivity models.
