Perceived workload and organizational citizenship behavior (OCB): The role of psychological empowerment
Authors: Wijaya Fef Rama Jaya , Purba Debora Eflina
Published: March 2021

Organizational Citizenship Behavior (OCB) is defined as an employee's voluntary behavior which is not formally rewarded in spite of its potential to increase the effectiveness and efficiency of the organization. This study aimed to investigate the mediating effect of psychological empowerment in the relationship between perception of workload and OCB. This study used the approach-avoidance motivation as the theoretical framework. Research data were collected using the snowball sampling method that was implemented in an online survey that targeted employees of various private organizations in Indonesia (N = 201). The measures used in this study were the 9-item workload subscale of the Job Demand-Resource Scale, 12-item Psychological Empowerment Questionnaire (PEQ), and 14-item OCB subscale of the Task Performance Scale. Data were analyzed using the simple mediation regression technique of Macro PROCESS developed by Hayes for SPSS software. The results of this study showed that perceived workload has a positive effect on psychological empowerment and psychological empowerment has a positive effect on OCB. Further, results showed that psychological empowerment mediates the relationship between perceived workload and OCB.
Mental budgeting and the malleability of decision-making
Authors: Elgeka Honey Wahyuni Sugiharto , Ma Jianhong
Published: March 2021

Financial difficulties commonly occur in college students' lives. Problems might be caused by a lack of understanding about managing money, such as falling into the temptation of buying unnecessary discounted goods or choice justification. The research aims to understand how mental budgeting influences purchasing discounted items and choice justification. In the study, two experiments were undertaken to explain the reaction of discount, and two others to describe choice justification (N=169 in Indonesia, N=168 in China). Mann-Whitney U and ANOVA tests were used to analyze the experiments. Mental budgeting scales were also employed in experiments 3 and 4. The results show that when individuals receive a discounted offer for luxury goods, they will fall into the temptation of buying them. This takes place because they do not want to lose the opportunity to obtain such goods at a cheap price. In addition, when individuals receive offers related to physiological needs (i.e., food), they will practice choice justification. This means that all people need to understand the concept of mental budgeting and make realistic budgets.

Reproductive parasitism in insects. The interaction of host and bacteria
Authors: Goryacheva Irina , Andrianov Boris
Published: March 2021

Reproductive parasitism is a specific form of symbiosis in which a microorganism alters the reproduction of the host by interfering with the mechanisms of sex development. The review considers four changes in reproduction — male killing, parthenogenesis, feminization, and cytoplasmic incompatibility — determined by cytoplasmic bacteria. The cytogenetic and molecular genetic mechanisms of interaction between partners in the symbiotic system are discussed, including the comparative analysis of molecular-genetic factors responsible for reproductive parasitism. The features of the interaction between an insect and bacteria in symbiosis with various systems for determining the sex of the host, male and female heterogamy and haplodiploidy, are considered. Studies of cytoplasmic incompatibility are of great practical importance, since they open up prospects for non-invasive engineering on natural insect populations for biocontrol.

Authors: Gultyaeva Elena , Levitin Mark , Shaydayuk Ekaterina
Published: March 2021

The article analyzes our own data and data from the literature on the study of plant–pathogen interactions in the pathosystem of Puccinia triticina and host plants of the genera Triticum and Aegilops with different ploidy and genomes. We characterize the long-term variability of the Russian populations of the pathogen, caused by the cultivation of genetically protected cultivars of common wheat (T. aestivum). Differences of the pathogen’s virulence on hexaploid species T. aestivum and tetraploid wheat (T. durum) are shown. Data on the pathogen’s virulence on other hexaploid, tetraploid, and diploid relative species Triticum sp. and Aegilops sp. are presented. Adaptation and specificity to the host plant were shown as the key driving factors in the evolution and divergence of clonally propagating phytopathogens, which include leaf rust.
New naturally transgenic plants: 2020 update
Authors: Matveeva Tatiana
Published: March 2021

Agrobacterium-mediated gene transfer leads to crown gall or hairy roots disease, due to expression of transferred T-DNA genes. Spontaneous plant regeneration from the transformed tissues can produce natural transformants carrying cellular T-DNA (cT-DNA) sequences of agrobacterial origin. In 2019, based on genomic sequencing data, cT-DNA horizontally transferred from Agrobacterium were found in two dozen species of angiosperms. This made it possible to evaluate the spread of this phenomenon, as well as make some generalizations regarding the diversity of horizontally transferred genes. The presented research is a continuation of work in this field. It resulted in the description of new naturally occurring transgenic species Aeschynomene evenia C. Wright, Eperua falcata Aubl., Eucalyptus cloeziana F.Muell., Boswellia sacra Flueck., Kewa caespitosa (Friedrich) Christenh., Pharnaceum exiguum Adamson, Silene noctiflora L., Nyssa sinensis Oliv., Vaccinium corymbosum L., Populus alba L. × Populus glandulosa Moench. The previously identified patterns regarding the frequency of the occurrence of natural transformants and the general properties of the cT-DNAs were confirmed in this study.
On the History of P.Chevalier de Brissol’s Ballet “The Village Heroine” (1800)
Authors:   Moscow State Tchaikovsky Conservatory, Maximova Alexandra E.
Published: March 2021

The article is devoted to the history of the creation and compositional features of P.Chevalier de Brissol’s ballet to the music of G.A. Pari “The Village Heroine”. Information was collected and clarified on the performances of the play, its authors and performers. Discrepancies were revealed in the studies (the date and place of the premiere, the number of acts, the names of choreographers and composers do not match). The creative continuity of the choreographers in working with the plot is noted and documentary information on the resumption of the ballet performed by A. Poireau, I. Walberh and A. Glushkovsky is provided. The libretto compositions were found and studied. In the article, the history of the plot related to the opera of P.Monsigny “Deserter”, the ballet of the same name by J.Doberval and other works are considered. For the first time, little-known handwritten musical sources of the ballet and its musical material are discussed. Textual features were studied, including handwritten litters containing the names of the creators, the dates of the ballet, as well as a rare autograph of the composer and bandmaster I. F. Kerzelli. The place of the composition in the work of Pari is determined and the conclusion is made that the musical score was compiled from the well-known works of different authors. In search of the authors of musical fragments, a complete verification of the score of the opera by P.Monsigny “Deserter” and the musical source “Village Heroine” was conducted. In the course of checking the score, a quote from the opera “Orpheus and Eurydice” by C.W. Gluck was discovered. The advantages of instrumentation and musical drama of ballet, built on thorough development and a system of thematic reprise, are revealed. It is established that Pari wrote music for its sequel — the ballet in three acts “The Consequence of the Village Heroine” (1806?), choreographed by Poireau and Valberkh.

Published: March 2021

Climate change is expected to increase in the future in the Mediterranean region, including Algeria. The Tafna basin, vulnerable to drought, is one of the most important catchments ensuring water self-sufficiency in northwestern Algeria. The objective of this study is to estimate the evolution of hydrological components of the Tafna basin, throughout 2020–2099, compared to the period 1981–2000. The SWAT model (Soil and Water Assessment Tool), calibrated and validated on the Tafna basin with good Nash at the outlet 0.82, is applied to analyze the spatial and temporal evolution of hydrological components over the basin throughout 2020–2099. The application is produced using a precipitation and temperature minimum/maximum of an ensemble of climate model outputs obtained from a combination of eight global climate models and two regional climate models of the Coordinated Regional Climate Downscaling Experiment project. The results of this study show that the decrease of precipitation in January, on average −25%, ranged between −5% and −44% in the future period. This diminution affects all of the water components and fluxes of a watershed, namely, in descending order of impact: the river discharge causing a decrease −36%, the soil water available −31%, the evapotranspiration −30%, and the lateral flow −29%.

Published: March 2021

Este estudo teve como objetivo levantar e descrever a avifauna do campus da Universidade Federal de Santa Catarina (UFSC) no município de Joinville, litoralnorte do estado de Santa Catarina, sul do Brasil. Foram realizadas cinco campanhas de campo, entre os anos 2010 e 2011, abrangendo todas as estações do ano e totalizando 23 dias de amostragem. A metodologia aplicada foi a busca direta por espécies (ad libitum), percorrendo quatro ambientes diferentes presentes na área de estudo. Foram registradas 174 espécies de aves, sendo 43 endêmicas do bioma da mata atlântica, seis ameaçadas de extinção e cinco quase ameaçadas (near threatened). Cada um dos ambientes presentes na área de estudo apresentou uma composição de espécies em particular. A elevada riqueza de espécies encontrada na pequena área do campus (120 ha) pode estar associada à alta diversidade regional e também à heterogeneidade ambiental do local. Destaca-se a importância da preservação de fragmentos florestais na porção nordeste do estado de Santa Catarina, em virtude da presença de espécies ameaçadas de extinção e endêmicas da mata atlântica detectadas nos remanescentes florestais na área de estudo.

Published: March 2021

Este trabalho teve como objetivo avaliar a produção de mudas de Moringa oleifera em função do manejo hídrico. O experimento foi conduzido em casa de vegetação na Universidade Federal Rural do Semi-Árido, em delineamento inteiramente casualizado, com três tratamentos: rega diária (RD), rega a cada 3 dias (R3D) e rega a cada 6 dias (R6D), com cinco mudas por tratamento. Avaliaram-se semanalmente a altura, o diâmetro e o número de folhas e, ao final do experimento, foi determinado o peso seco da folha, do caule e da raiz, assim como a alocação de biomassa foliar, caulinar e radicular, além do índice de qualidade de Dickson. Os diferentes intervalos de rega não afetaram as variáveis avaliadas, com exceção do número de folhas e a alocação de biomassa foliar, que foram reduzidos para o tratamento R6D. Em condições de viveiro, pode ser adotado o ciclo de rega a cada 3 dias, sem prejuízos no desenvolvimento da espécie em foco, ou a cada 6 dias, embora nesse caso haja perda de folhas, com benefícios ambientais e econômicos tanto para o produtor quanto para a natureza.

Authors: Xu Wen , Wang Bei , Cai Yuxuan , Chen Jinlan , Lv Xing , Guo Chong , Yuan Chengfu
Published: March 2021

Background:

Long non-coding RNAs (lncRNA) have been identified as novel molecular regulators
in cancers. LncRNA ADAMTS9-AS2 can mediate the occurrence and development of cancer through various
ways, such as regulating miRNAs, activating the classical signaling pathways in cancer, and so on, which have
been studied by many scholars. In this review, we summarize the molecular mechanisms of ADAMTS9-AS2 in
different human cancers.

Methods:

Through a systematic search of PubMed, lncRNA ADAMTS9-AS2 mediated molecular mechanisms
in cancer are summarized inductively.

Results:

ADAMTS9-AS2 aberrantly expression in different cancers is closely related to cancer proliferation, invasion,
migration, and inhibition of apoptosis. The involvement of ADAMTS9-AS2 in DNA methylation, mediating
PI3K / Akt / mTOR signaling pathways, and regulating miRNAs and proteins, shows its significant potential
as a therapeutic cancer target.

Conclusion:

LncRNA ADAMTS9-AS2 can become a promising biomolecular marker and a therapeutic target for human cancer.
Synaptotagmin-1: A Multi-Functional Protein that Mediates Vesicle Docking, Priming, and Fusion
Authors: Ullah Najeeb , Maaiden Ezzouhra El , Uddin Md. Sahab , Ashraf Ghulam Md.
Published: March 2021

The fusion of secretory vesicles with the plasma membrane depends on the assembly of
v-SNAREs (VAMP2/synaptobrevin2) and t-SNAREs (SNAP25/syntaxin1) into the SNARE complex.
Vesicles go through several upstream steps, referred to as docking and priming, to gain fusion
competence. The vesicular protein synaptotagmin-1 (Syt-1) is the principal Ca2+ sensor for fusion
in several central nervous system neurons and neuroendocrine cells and part of the docking complex
for secretory granules. Syt-1 binds to the acceptor complex such as synaxin1, SNAP-25 on the
plasma membrane to facilitate secretory vesicle docking, and upon Ca2+-influx, it promotes vesicle
fusion. This review assesses the role of the Syt-1 protein involved in the secretory vesicle docking,
priming, and fusion.

Voxel-wise Functional Connectivity of the Default Mode Network in
Epilepsies: A Systematic Review and Meta-Analysis
Authors: Jiang Sisi , Li Hechun , Liu Linli , Yao Dezhong , Luo Cheng
Published: March 2021

Background:

Default mode network (DMN) is recognized to be involved in generation and propagation of epileptic activities in various epilepsies. Converging evidence has suggested disturbed functional connectivity (FC) in epilepsies, which was inferred to be related to underlying pathological mechanisms. However, abnormal changes of FC in DMN revealed by different studies are controversial, which obscures the role of DMN in distinct epilepsies.

Objective:

The present work aims to investigate the voxel-wise FC in DMN across epilepsies.

Methods:

A systematic review was conducted on 22 published articles before October 2020 indexed in PubMed and Web of Science. A meta-analysis with a random-effect model was performed using the effect-size signed differential mapping approach. Subgroup analyses were performed in three groups: idiopathic generalized epilepsy (IGE), mixed temporal lobe epilepsy (TLE), and mixed focal epilepsy (FE) with different foci.

Results:

The meta-analysis suggested common decreased FC in mesial prefrontal cortices across different epilepsies. Additional decreased FC in posterior DMN was observed in IGE. The TLE showed decreased FC in temporal lobe regions and increased FC in dorsal posterior cingulate cortex. Interestingly, an opposite finding in ventral and dorsal middle frontal gyrus was observed in TLE. The FE demonstrated increased FC in cuneus.

Conclusion:

The current findings revealed both common and specific alterations of FC in DMN across different epilepsies, highlighting the contribution of these dysfunctions to epileptic activities and cognitive behaviors in patients. Furthermore, the current study provided powerful evidence to support DMN as a potential candidate for effective intervention in epilepsy.

Published: March 2021

Indonesia, as one of the largest majority Muslim countries, has had a consistent stance on the Israel-Palestine conflict since its inception. Despite the general pro-Palestinian stance, this article explores the discourse of three significant leaders of the Indonesian people - Soekarno, Abdurrahman Wahid and Ahmad Syafii Maarif. As presidents of Indonesia of different time periods of Indonesia, Soekarno and Wahid tended to be pragmatic in their articulation of their political stances, though it is articulated in different ways. Maarif, as the leader of Muhammadiyah, a popular non-governmental organisation on the ground, was more idealistic and concerned with anti-Zionism. This article highlights that the different nuances of the three leaders is due to their different capacities as leaders, their social and political contexts, and the intellectual leanings and experiences.

Published: March 2021

Deniz, göl ve akarsu kıyıları; sahip oldukları doğal, sosyal, kültürel ve ekonomik potansiyeller ile bugüne kadar yaşayan tüm toplumlar için talep edilen alanlar olmuştur. Böylesine ilgi odağında olan kıyılar, sunduğu olanaklar nedeniyle sürekli toplumsal baskı altındadır. Kıyı alanlarının kullanımı ve planlamasında sürdürülebilirliğe yönelik kurumsal çalışmalar, üç tarafı denizlerle çevrili olan, zengin göl ve akarsu yataklarına sahip Türkiye için büyük önem arz etmektedir. Ancak, bir taraftan yürürlükte olan kıyı mevzuatındaki yetersizlikler ve sıkça yapılan değişikler, diğer taraftan idari denetim ve hukuki yaptırımlardaki yetersizlikler, yaşanan sorunların başlıca kaynağını oluşturmaktadır. Bu sebeple, kıyı yönetiminde ‘karar alma, planlama yapma ve uygulamaya koyma’ konusunda kıyı alanlarının iyi yönetildiğini söylemek zordur. Türkiye’de mülkiyet hukuku yönünden kıyılar; Türkiye Cumhuriyeti Anayasası’nın 43. maddesi ve Türk Medeni Kanunu’nun 715. maddesine göre ‘devletin hüküm ve tasarrufu altındaki’ yerlerdendir. Böylesi alanların belirli bir zümre veya kişi mülkiyetine konu olması mümkün değildir. Kıyıların, toplumun her kesimi için eşit, karşılıksız ve serbestçe yararlanmasına ayrılan ortak kullanım alanları olması gerekmektedir. Ancak bu durum, geçmişte hukuka uygun olarak kazanılmış kıyı alanlarındaki taşınmazlara ait tapuların, daha sonra kamu yararı sağlamak amacıyla yargıya konu edilmesi ile fiili kullanımda hala önemli bir mülkiyet sorunu olmaya devam etmekte ve yargıyı meşgul etmektedir. Bu çalışmanın amacı, Türkiye coğrafyasından farklı örnekler eşliğinde ekolojik, ekonomik ve toplumsal değerlere sahip deniz, göl ve akarsu kıyılarında yaşanan kıyı kenar çizgisi-mülkiyet sorunlarını ortaya koyup, çözüm önerileri geliştirmektir.

Heart failure (HF) is a major clinical, social, and economic problem. In view of the important role of fluid overload in the pathogenesis of HF exacerbation, early detection of fluid retention is of key importance in preventing emergency admissions for this reason. However, tools for monitoring volume status that could be widely used in the home setting are still missing. The physical properties of human tissues allow for the use of impedance-based noninvasive methods, whose different modifications are studied in patients with HF for the assessment of body hydration. The aim of this paper is to present the current state of knowledge on the possible applications of these methods for remote (home-based) monitoring of patients with HF.

Introduction/Main Objectives: Leadership is important in enabling a person and a nation to improve and advance.  Background Problems: Leadership is not something that everyone seeks, especially in youth. The youth leadership crisis can be seen from the lack of students who want to become chairpersons in university extracurricular activities. Novelty: This research makes a three-fold contribution. First, this study presents an analysis of the ‘Evolving Leadership Practices Assessment’ quizzes (Olson and Singer, 2004) distributed by the Chairperson and Vice-chairperson of the Library Science Student Association (IMASIP) the Faculty of Humanities, Universitas Indonesia. Second, this study assesses the IMASIP FIB-UI Daily Management Board. This study also interviewed five informants with 12 closed-ended questions. Research Methods: This paper assesses youth leadership by using a mix of qualitative and quantitative methods, with a case study approach.  Finding/Results: Our result shows and supports the assumption that age and years of leadership will affect the scores obtained at IMASIP, which further research must examine. This research also suggests that the Daily Management Board's performance can be maintained by connection, contribution, and collaboration. Conclusion: The results identify efforts to build and improve leadership among students, including developing and increasing seminars and training in leadership to prepare students who have a role as the successors of the nation’s leadership.

Linking the concept of sustainable development, as demanding per capita prosperity does not decline over a long period of time, and the concept of competitiveness, which reflects the level of productivity of national economies, is a new approach to development called sustainable competitiveness. The care for the scarcity of resources and the preservation of their base so that future generations will have the same level of well-being as today's generation have, requires the incorporation of environmental and social issues and problems into the concept of competitiveness. In this way, a new context of competitiveness analysis is introduced and is meeting the challenges of the concept of sustainable development.The methodology of the composite index of sustainable competitiveness was first developed by the World Economic Forum (WEF), followed by organizations such as SolAbility - Sustainable Intelligence. SolAbility methodology of Global Sustainable Competitiveness Index (GSCI) creation is the subject of research in this paper. The aim of research is the proposal of a new methodology for calculating GSCI based on different weights assigned to the pillars included in the Index. The paper concludes that the highest relative importance in the structure of the GSCI belongs to the Intellectual capital dimension. The originality of this work is reflected in the creation of a new ranking of countries in terms of sustainable competitiveness. An analysis of possible changes in the ranking list is a good basis for a new analysis of the sustainable competitiveness of countries, in which some of the professional and statistical rules comments on its calculation methodology are accepted.

Depending on the inclination of the authors and the focus of their security research, we recognize two most common approaches: the first focuses on the stability of national governance structures and territorial integrity (state and/or national security); while the second approach focuses on security as a civil right in daily life, the availability of necessary resources and the quality of life. The latter approach is known in theory as the concept of human security. Considering the fact that a comprehensive analysis of the security situation involves elements of both approaches, in the paper we consider the complex relationship between state and non-state security actors through the hybridization of the political system. The mismatch between the level of the national strategy and its operationalization at the level of meeting the needs of citizens requires the introduction of new elements in the space between the strategic and operational levels. The outlined approach can be called the Hybrid Security System because of its potential contribution to raising the level of Human Security (HS) in local communities. We will present the hybrid security system conceptually in the form of a decentralized computer network. The presented diagram of System Dynamics and the proposed model of HS operationalization through the hybridization of security systems using the potential of Information and Communications Technologies are a good basis for the analysis and raising the level of citizens’ security in relation to current threats.

O Plano Brasil Sem Miséria foi criado para gerar transferência de renda, acesso aos serviços públicos e inclusão produtiva a famílias que vivem abaixo da linha da pobreza (MDS, 2015). Para contribuir com o Plano, a Embrapa Agroindústria Tropical iniciou um projeto com a finalidade de transferir Tecnologias Sociais para 10 municípios do Território do Alto Oeste Potiguar, RN. Assim, este artigo tem como objetivo identificar as vantagens e desvantagens funcionais da tecnologia fogão ecoeficiente e avaliar o nível de satisfação, com a sua adoção, por parte das famílias da zona rural do município de Luís Gomes, RN. Das 31 famílias beneficiadas, foi selecionada uma amostra de 25, correspondendo a 80,6% dos beneficiários. A coleta dos dados foi realizada por meio de entrevistas e aplicação de questionário. Observou-se que as condições socioeconômicas dos beneficiários são precárias, que o fogão ecoeficiente apresenta mais vantagens que desvantagens em termos de funcionalidade como rapidez no cozimento, menor consumo de lenha e facilidade do manuseio, em comparação com o fogão convencional, e que 61% das famílias beneficiadas apresentam-se satisfeitas com a tecnologia.
ANÁLISE DA COMPOSIÇÃO E DISTRIBUIÇÃO DAS RECEITAS DE ESTABELECIMENTOS FAMILIARES NA REGIÃO NORDESTE

Published: March 2021

Este artigo tem como objetivo caracterizar a composição das receitas e rendas de estabelecimentos agropecuários que integram o modelo familiar e identificar a presença de padrões de comportamento espacial entre as receitas e seus componentes na região Nordeste do Brasil. Para tanto, foram realizadas análises descritivas de dados do Censo Agropecuário 2017 e uma abordagem espacial através do cálculo do Índice I de Moran, para medir a presença de autocorrelação espacial, e análise de clusters, para verificar o comportamento das receitas na região. Os resultados apontam para heterogeneidades entre os modelos familiar e não familiar na região e indicam uma grande dependência do produtor familiar a fontes externas de rendas, a exemplo das aposentadorias e pensões. Apesar da fraca autocorrelação espacial, os clusters das receitas externas e rendas provenientes de políticas e programas governamentais se sobrepõem à área abrangida pelo semiárido, indicando maior dependência desses recursos nesses municípios.
O CONCEITO DE AGRICULTURA FAMILIAR: RETROCESSOS DO PRESENTE
Authors: Fossá Juliano Luiz , Renk Arlene
Published: March 2021

Este artigo tem por objetivo demonstrar os retrocessos por parte do Governo Federal quanto ao entendimento do conceito de agricultura familiar a partir de meados do ano de 2016. O conceito de agricultura familiar, que parecia cristalizado desde o início da década de 1990, vê-se em torno de um novo entendimento que retrocede à ideia de pequeno produtor, pequena produção, superada há três décadas pela sociedade brasileira. A realização deste estudo apoiou-se na abordagem qualitativa, caracterizando-se como um ensaio teórico. Por meio de uma pesquisa bibliográfica foi analisada a literatura a respeito, bem como as medidas legais e ações políticas do Executivo Federal em relação à agricultura familiar no País. A reestruturação do Governo Federal a partir de maio de 2016 resultou na extinção do MDA. Esta medida, por sí só, representa que a agricultura brasileira a partir de então será tratada da mesma forma pelo Governo Federal, neste caso sob a tutela do MAPA. Outra medida é a criação do termo Unidade Familiar de Produção Agrária (UFPA) por meio do Decreto Presidencial 9.064/2017, que reduz a agricultura familiar somente à ideia de produção agropecuária. Trata-se de uma forma simplista de delinear toda diversidade presente no conceito de agricultura familiar, pois para além de um território produtivo, o rural se coloca como um espaço de vida. É possível concluir, que há uma série de medidas e ações do Governo Federal a partir de maio de 2016 destinadas a um “novo” entendimento do conceito de agricultura familiar. Tal percepção retrocede no tempo e simplifica um conceito complexo e amplo construído há muitas mãos durante décadas. O conceito de agricultura familiar é marcado por continuidades e rupturas, contudo uma ampla movimentação em torno desse debate se faz necessário para garantia, especialmente no que tange a políticas públicas diferenciadas.
ANALYSIS OF CONVEYOR DRIVE POWER REQUIREMENTS IN THE MINING INDUSTRY
Authors: Wheatley Greg , Rubel Robiul
Published: March 2021

This article presents the analysis of conveyor drive power requirements for three typical mining conveyors. One of the conveyors was found not to be able to start when fully loaded. The analysis indicates that two of the conveyors are adequately powered while one is underpowered. This was found to be primarily the result of the maximum tonnage of the two adequately powered conveyors being 1500 tonnes per hour (TPH) while the inadequately powered conveyor was classed with a maximum tonnage of 1800 TPH. It is recommended that the current draw for each motor when fully loaded be measured. This will be compared to the design. Further analysis was done to allow 2000 TPH on all conveyors. The required upgraded drive size is presented. This article does not address the structural adequacy of the supporting structure. Rather, only the capabilities of the conveyor belt and drives to transport the required TPH.

Sustainable human resource management is one of the distinguished approaches for ensuring the organizational performance of an organization in today's turbulent business environment. Human resource management ensures the achievement of the organizational goals through practices of managing human resources. Sustainable human resource management thereby ensures the development and maintenance of the potential of all employees in the organization. The main goal of this paper is to present the results of research in the field of human resource management with respect to different generations of employees in industrial enterprises operating in the Slovakia. The research sample consisted of n = 1 471 respondents (employees of industrial enterprises). The most important results of the prezented research is the finding that employees of industrial enterprises consider work performance, which influences their remuneration, to be important. The research showed that there are statisticaly significant relationships between employees at managerial and production positions and the perceived importance of work performance when determining the income of managers and production employees (rs = 0.274 and rs = 0.363).
The types of visible scientists
Authors: Olesk Arko
Published: March 2021

We lack a good framework to characterize media-related adaptations of researchers. This paper explores Estonian scientists visible in the media to propose five dimensions to characterize the degree of mediatization of a researcher, and describes two basic types of visible scientists. Representatives of one type (‘adapters to media logic’) are able to explain the project simply and engagingly in the media, while those of the second type (‘adopters of media logic’) proactively create media interactions and manage them to achieve strategic aims. The results show how individual actors translate communication objectives into media practices, explaining variabilities in scientists' media presence.
