Filling the Gap between Ecosystem Services Concept and River Basin Management Plans: The Case of Greece in WFD 20+
Authors: Kagalou Ifigenia , Latinopoulos Dionissis
Published: September 2020

The ecosystem services (ES) concept is embedded in all new European directives but its integration in the Water Framework Directive (WFD) is absent, despite the latter being the major legislative tool. The research aims to assess the knowledge of ES that lies within the River Basin Management Plans (RBMPs) in Greece so as to further depict their representation in the relevant planning tools, to support policy making and express the implementation experience to Member States for assisting EU reloading processes. The information on the ES’ status was extracted by the official RBMPs, processed and grouped following Common International Classification of Ecosystem Services (CICES) classification. The prioritization of ES included in the programs of measures (PoMs) further showed the targeting for each River Basin District (RBD). The results were not homogenous for the RBDs, revealing different needs in measures and indicating there is a lack in “communication” between the relevant EU and national regulations. Moreover, a wide suite of water-related ES is hindered in addressing multiple benefits coming from provisioning, regulating and cultural ES. For a proper WFD reload and continuation, the infusion of the ES concept and prerequisites in its objective, and the reviewing of the RBMPs’ target and the suggestion of integrated PoMs are necessary steps that could deliver added value in such legislation.
A Well-Being Approach to Soil Health—Insights from Aotearoa New Zealand

Published: September 2020

This paper explores the concept of soil health from a human well-being perspective in Aotearoa New Zealand. Globally, soils play an integral role in wider society and the environment by maintaining a large range of ecosystem services and benefits. As populations and resource constraints increase and food production and food security become growing issues globally, there is a recognition of the importance of defining soil condition or soil health for sustaining all ecosystems, including services and benefits to humans, plants, animals, and micro-organisms. While the ecosystem services approach has helped to illuminate the varied services soils provide, an understanding of the complex human–soil relationships and values has been missing. Those seeking to understand and form concepts about soil health have concentrated on the more inherent biochemical, physical and economic (e.g., productivity) aspects of soils, but not on the human, social or cultural dimensions. It is argued in this paper that soils form an integral part of our social and cultural fabric and are fundamentally important to human and societal well-being. The way humans interact with, value and use soil is a critical part of determining the health and sustainability of soil ecosystems. We discuss how a well-being approach can improve understanding of soil health with respect to societal goals and needs. We believe this type of approach, which includes social and cultural dimensions, provides a more diverse and inclusive knowledge base and perspective to better inform the development of integrative policy. This would lead to improved management and decision-making of land resources and soils in Aotearoa New Zealand and globally.

Published: September 2020

The environmental impact produced by digital technologies is one of the fundamental contents to be developed by teachers of the 21st century. Different investigations raise the need to redesign education towards sustainable models and promote a critical look at digital technologies. The main objective of this manuscript is to design a valid, reliable and useful scale to measure self-perceived teacher digital competence regarding the eco-responsible use of technologies. The instrument has been designed based on a detailed analysis of the main frameworks for the development of digital competence in Europe: INTEF and DigCompEdu. A content validation process has been followed through the expert judgment method. Subsequently, its reliability and validity are estimated using structural equation modeling techniques. The results obtained guarantee the reliability and validity of the model. Therefore, the need to establish environmental teacher training plans and more awareness about the eco-responsible use of technologies is established.
Managing Corporate Sustainability and Responsibility Efficiently: A Review of Existing Literature on Business Groups and Networks
Authors: Liakh Olena , Spigarelli Francesca
Published: September 2020

Given the global relevance of business groups (BG) and networks as efficient organizational forms for corporate sustainability and responsibility systems (CSR), and seeing that management control systems (MCS) play a pivotal role in transmitting authority to CSR and formalizing a sustainability organizational culture, this paper aims to review the available literature in order to investigate efficient adoptions of CSR by BGs or networks. Both organizational forms have positive effects on CSR development, on three levels: (a) setting industry standards (macro—external environment); (b) stimulating sustainability-oriented innovations (mezzo—member firms); (c) reputational gains, CSR expenses mitigation, and optimization of organizational capabilities (micro—individual SMEs). The studies on SMEs were useful in identifying current sustainability practices: both partial (social, environmental) and complete sustainability systems were susceptible to being integrated with management accounting, making them an almost implicit tool for proper CSR. Finally, by gathering the empirical literature on sustainability transitions of networks and groups, it was possible to trace a comprehensive introductory plan that operators could resort to for initial guidance. The six steps of this process are (1) project initiation, (2) preliminary actions, (3) change management decision, (4) firm-level activities, (5) auditing, (6) transition to territorial social responsibility (optional).
Potential Bioenergy Production from Miscanthus × giganteus in Brandenburg: Producing Bioenergy and Fostering Other Ecosystem Services while Ensuring Food Self-Sufficiency in the Berlin-Brandenburg Region
Authors: Tavakoli-Hashjini Ehsan , Piorr Annette , Müller Klaus , Vicente-Vicente José Luis
Published: September 2020

Miscanthus × giganteus (hereafter Miscanthus) is a perennial crop characterized by its high biomass production, low nutrient requirements, its ability for soil restoration, and its cultivation potential on marginal land. The development of the bioenergy sector in the state of Brandenburg (Germany), with maize as the dominant crop, has recently drawn attention to its negative environmental impacts, competition with food production, and uncertainties regarding its further development toward the state’s bioenergy targets. This study aimed to estimate the potential bioenergy production in Brandenburg by cultivating Miscanthus only on marginal land, thereby avoiding competition with food production in the Berlin-Brandenburg city-region (i.e., foodshed), after using the Metropolitan Foodshed and Self-sufficiency Scenario (MFSS) model. We estimated that by 2030, the Berlin-Brandenburg foodshed would require around 1.13 million hectares to achieve 100% food self-sufficiency under the business as usual (BAU) scenario, and hence there would be around 390,000 ha land left for bioenergy production. Our results suggest that the region would require about 569,000 ha of land of maize to generate 58 PJ—the bioenergy target of the state of Brandenburg for 2030—which is almost 179,000 ha more than the available area for bioenergy production. However, under Miscanthus plantation, the required area would be reduced by 2.5 times to 232,000 ha. Therefore, Miscanthus could enable Brandenburg to meet its bioenergy target by 2030, while at the same time avoiding the trade-offs with food production, and also providing a potential for soil organic carbon (SOC) sequestration of around 255,200 t C yr-1, leading to an improvement in the soil fertility and other ecosystem services (e.g., biodiversity), compared with bioenergy generated from maize.

Published: September 2020

In the current context, higher education faces the challenge of preparing future professionals to respond to society’s increasingly complex problems. However, the search for solutions means adopting new ways of working that promote multidimensionality through collaboration and an interdisciplinary outlook. In this change of paradigm, universities should work on the development of sustainability education, promoting critical reflection and the necessary skills to generate a change in thinking and real practice for sustainability, through incorporation of methodologies that foster collaborative teaching and working. The main aim of the present study was to design, implement, and assess an experience based on the case study methodology, approached from an interdisciplinary perspective. By designing repeated pretest–posttest measures, we analyzed changes in learning skills linked to interdisciplinarity, such as collaborative work, participation, motivation, and interdisciplinary thinking. The sample comprised 539 university undergraduates from Social Education, Primary Education, and Psychology degree courses. The results confirmed that the methodology used improved interdisciplinary outlook, participation, cooperation, and motivation. The implications of this type of innovative experience for the teaching–learning process of university students are discussed.
The Role of Social Media on Tourists’ Behavior: An Empirical Analysis of Millennials from the Czech Republic
Authors: Javed Mohsin , Tučková Zuzana , Jibril Abdul Bashiru
Published: September 2020

Due to the emergence of Web 2.0 and consequently the increased use of social media, this study aims to explore the role of social media in changing the behavior of tourists and the choice of a destination. Despite the massive popularity of social media, the studies with a comprehensive set of driving constructs along with indicators of social media regarding the changing behavior of tourists are lacking in the literature. Therefore, framed by the theory of planned behavior (TPB), the present study fulfills this research gap by developing a set of driving constructs and carrying out an empirical analysis by collecting data from millennials in the selected universities of the Czech Republic. Through the non-random sampling technique, precisely convenience sampling, 261 valid responses were received, and partial least squares-structural equation modeling (PLS-SEM) analysis was performed to achieve the objectives of this study. The results indicate that social media channels have a significant impact on behavioral intention and the actual behavior of tourists (significant direct and indirect effect). The constructs tourist information search and tourism promotion were partially supported toward predicting the behavior of tourists. Control–variables related to socio-economic characteristics such as gender and educational level also have a significant impact in determining the actual behavior of tourists. Hence, overall, the study concludes with the significant and considerable impact of social media on the behavior of tourists. The contributions of the study and future directions are discussed at the end of the paper.

In Nicaragua, there are ideal environmental conditions for leptospirosis. The objective of this investigation was to detect pathogenic and saprophytic leptospires in water and soil samples from leptospirosis-endemic areas in Nicaragua. Seventy-eight water and 42 soil samples were collected from houses and rivers close to confirmed human cases. Leptospira spp was isolated in Ellinghausen–McCullough–Johnson–Harris (EMJH) culture medium with 5-fluororacil and positive samples were analyzed through PCR for the LipL32 gene, specific for pathogenic leptospires (P1 clade). There were 73 positive cultures from 120 samples, however only six of these (5% of all collected samples) were confirmed to be pathogenic, based on the presence of the LipL32 gene (P1 clade). Of these six pathogenic isolates, four were from Leon and two from Chinandega. Four pathogenic isolates were obtained from water and two from soil. This study proved the contamination of water and soil with pathogenic leptospires, which represents a potential risk for public health.
Evidence for Solar Modulation on the Millennial-Scale Climate Change of Earth
Authors: Zhao Xinhua , Soon Willie , Velasco Herrera Victor M.
Published: September 2020

In this study, we use available reconstructed data to investigate periodicities of solar activity (i.e., sunspot number) and the Earth’s climate change (temperatures of Lake Qinghai in China and Vostok in Antarctica, the GISP δ18O climate record of Greenland, and the stalagmite δ18O monsoon records of Dongge Cave in China) as well as their cross-wavelet coherences on millennial scale. We find that the variations of the Earth’s climate indices exhibited the 1000-year cyclicity, which was recently discovered in solar activity (called Eddy cycle). The cross-wavelet correlations between the millennium-cycle components of sunspot number and the Earth’s climate change remains both strong and stable during the past 8640 years (BC 6755–AD 1885). The millennial variation of sunspot number keeps in-phase with variations of Lake Qinghai temperature, Greenland temperature, and East Asian Monsoon, but anti-phase with the variation of Antarctica temperature. The strong and stable resonant relationships between sunspot numbers and these climate indices indicate that solar variability may have played a role in modulation on this millennial seesaw pattern of the Earth’s climate change before the modern industrial era.
Merkel Cell Polyomavirus Large T Antigen Unique Domain Regulates Its Own Protein Stability and Cell Growth
Authors: Nwogu Nnenna , Ortiz Luz E. , Kwun Hyun Jin
Published: September 2020

Merkel cell polyomavirus (MCV) is the only known human oncogenic virus in the polyomaviridae family and the etiological agent of most Merkel cell carcinomas (MCC). MCC is an aggressive and highly metastatic skin cancer with a propensity for recurrence and poor prognosis. Large tumor antigen (LT), is an essential oncoprotein for MCV transcription, viral replication, and cancer cell proliferation. MCV LT is a short-lived protein that encodes a unique domain: MCV LT unique regions (MURs). These domains consist of phosphorylation sites that interact with multiple E3 ligases, thus limiting LT expression and consequently, viral replication. In this study, we show that MURs are necessary for regulating LT stability via multiple E3 ligase interactions, resulting in cell growth arrest. While expression of wild-type MCV LT induced a decrease in cellular proliferation, deletion of the MUR domains resulted in increased LT stability and cell proliferation. Conversely, addition of MURs to SV40 LT propagated E3 ligase interactions, which in turn, reduced SV40 LT stability and decreased cell growth activity. Our results demonstrate that compared to other human polyomaviruses (HPyVs), MCV LT has evolved to acquire the MUR domains that are essential for MCV LT autoregulation, potentially leading to viral latency and MCC.
Cognitive and Memory Functions in Plant Immunity
Authors: Yakura Hidetaka
Published: September 2020

From the time of Thucydides in the 5th century BC, it has been known that specific recognition of pathogens and memory formation are critical components of immune functions. In contrast to the immune system of jawed vertebrates, such as humans and mice, plants lack a circulatory system with mobile immune cells and a repertoire of clonally distributed antigen receptors with almost unlimited specificities. However, without these systems and mechanisms, plants can live and survive in the same hostile environment faced by other organisms. In fact, they achieve specific pathogen recognition and elimination, with limited self-reactivity, and generate immunological memory, sometimes with transgenerational characteristics. Thus, the plant immune system satisfies minimal conditions for constituting an immune system, namely, the recognition of signals in the milieu, integration of that information, subsequent efficient reaction based on the integrated information, and memorization of the experience. In the previous report, this set of elements was proposed as an example of minimal cognitive functions. In this essay, I will first review current understanding of plant immunity and then discuss the unique features of cognitive activities, including recognition of signals from external as well as internal environments, autoimmunity, and memory formation. In doing so, I hope to reach a deeper understanding of the significance of immunity omnipresent in the realm of living organisms.
Optimal Parameter Estimation in Activated Sludge Process Based Wastewater Treatment Practice
Authors: Du Xianjun , Ma Yue , Wei Xueqin , Jegatheesan Veeriah
Published: September 2020

Activated sludge models (ASMs) are often used in the simulation of the wastewater treatment process to evaluate whether the effluent quality parameters of a wastewater treatment plant meet the standards. The premise of successful simulation is to choose appropriate dynamic parameters for the model. A niche based adaptive invasive weed optimization (NAIWO) algorithm is proposed in this paper to find the appropriate kinetic parameters of activated sludge model 1 (ASM1). The niche idea is used to improve the possibility of convergence to the global optimal solution. In addition, the adaptive mechanism and periodic operator are introduced to improve the convergence speed and accuracy of the algorithm. Finally, NAIWO is used to optimize the parameters of ASM1. Comparison with other intelligent algorithms such as invasive weed optimization (IWO), genetic algorithm (GA), and bat algorithm (BA) showed the higher convergence accuracy and faster convergence speed of NAIWO. The results showed that the ASM1 model results agreed with measured data with smaller errors.
Removal Mechanism and Effective Current of Electrocoagulation for Treating Wastewater Containing Ni(II), Cu(II), and Cr(VI)

Published: September 2020

This study aims to clarify the removal mechanism and to calculate the effective current of electrocoagulation (i.e., EC) for treating wastewater containing Ni(II), Cu(II), and Cr(VI). The adsorption behavior of various heavy metals onto Al(OH)3 coagulant generated by the EC process was investigated and the estimating method of the corresponding current was established. Results indicate that adsorption of single Ni(II) and Cu(II) by Al(OH)3 coagulant can be simulated by the Langmuir isotherm, while Cr(VI) adsorption fits the Freundlich isotherm better. As treating single heavy metal of wastewater, the removal mechanism of the EC process is the adsorption reaction. Under the coexisting condition, the Ni(II) and Cu(II) will compete for the same active sites on the Al(OH)3 surface and Cu(II) suppresses Ni(II) adsorption. As treating the coexisting heavy metals, Ni(II) removal not only associates with adsorption but also with the coprecipitation. In contrast, Cr(VI) does not compete with other metal ions for the same type of adsorption sites. Whether single or coexisting conditions, the adsorption capacity of heavy metals onto Al(OH)3 coagulants can be used to compute the necessary current to effectively remove heavy metals in the EC system.

Published: September 2020

The quantitative inversion of the concentrations of water quality parameters could clarify the temporal and spatial distribution characteristic, migration, and conversion of water quality parameters. This study took the Danjiangkou Reservoir as the research object, and established an inversion model based on the reflectance of different band combinations of remote sensing analyses on Sentinel-2 images, combined with the water quality monitoring data of total nitrogen (TN) and ammonia nitrogen (NH3-N) of the sampling sites in February 2016. The inversion results of TN and NH3-N in 2020 were obtained, the variation of TN and NH3-N concentrations in the reservoir area were analyzed, and the factors accounting for the variation were discussed. The results indicated that the fitting accuracy using the established model was high for both TN and NH3-N, and R2 was 0.782 for TN and 0.851 for NH3-N, respectively, showing high predication accuracy, which could be suitable for remote sensing inversion of TN and NH3-N concentrations in the Danjiangkou Reservoir. The NH3-N concentration of the Danjiangkou Reservoir was in line with Class I from 2016 to 2020, while the TN concentration was between Class III and IV. The inter-annual changes indicated that the overall water quality had an upward trend. The main tributary in the northern of the Danjiangkou Reservoir had a heavy load of TN, and after entering the reservoir, the flow velocity decreased, which caused nitrogen to accumulate at the river entrance, leading to a high TN concentration. The large slope of the mountainous area cause soil erosion. The lost soil and water carried a large amount of pesticides and fertilizers, and the ground runoff carried a large amount of nitrogen into water body, which could account for the high NH3-N concentration on the east and west sides of the southern part of the Danjiangkou Reservoir.

A pesquisa tem como objetivo analisar os custos e a produtividade da soja convencional e transgênica no Brasil no período de 2017 e 2018. Esse estudo se caracteriza como quantitativo e descritivo. Utilizou-se de dados secundários de custos da produção da soja, safras de 2017 e 2018, no Brasil, obtidos no site da Companhia Nacional de Abastecimento (CONAB, 2018). Os dados foram organizados numa planilha do Excel e posteriormente submetidos a testes estatísticos, como correlação de Spearman, teste T de Mann-Whitney e regressão linear múltipla, por meio do software Statistical Package for the Social Sciences (SPSS) versão 24. Os achados evidenciam que existem distinções entre os custos e produtividade entre a soja convencional e transgênica. Uma vez que os custos com agrotóxicos explicam 49% da produtividade da soja transgênica, e ainda, os custos com agrotóxicos possui diferença estatisticamente significativa em comparação com a soja convencional. Além disso, os custos com agrotóxicos apresentaram alta correlação com a produtividade e os custos de fertilizantes, resultado esse não encontrado para a soja convencional.

Published: September 2020

Introduction: Concomitant onset of active systemic lupus erythematosus (SLE) and psoriasis is rare; however, due to the common skin involvement in both and exacerbation of psoriasis with antimalarial medications used for SLE, it is crucial to investigate the concomitant occurrence of both diseases. Objectives: The present study aims to investigate the incidence of psoriasis in people with active SLE. Patients and Methods: The present cross-sectional study was performed on 148 patients with active SLE from 2015 to 2017. Lupus activity was evaluated based on systemic lupus erythematosus disease activity index-2K (SLEDAI-2K), and then, the incidence of psoriasis in patients was investigated. Patients’ demographic information was recorded in the relevant checklist. Results: The mean score of SLEDAI-2K was 14.10±19.77. The duration of SLE was significantly associated with the SLEDAI-2K score (P=0.001, r = 0.294). Psoriasis incidence was remarkably correlated with the gender of patients with SLE (P=0.019). An insignificant association was found between the coincidences of SLE with psoriasis considering the factors, including age, SLE duration, and mean SLEDAI-2K score. Conclusion: Patients’ mean age, SLE duration, and disease activity score were not correlated with concomitant psoriasis among SLE patients; however, we found that males were more prone to concomitant SLE and psoriasis.

Published: September 2020

Mechanical properties of two samples of decking boards were measured after exposure in rain and chlorinated water, in ice, and in a mixture of gasoline and water in diﬀerent concentrations from 1 to 7%. Samples consisting of 60% wood flour, 30% polyvinyl chloride and 10% additives were used for measurements. Additives are flame retardants, stabilizers, modifiers and dyes. The mineral filler CaCO3 was used as modifiers. For sample №1, the CaCO3 content was 42% and the wood content was 18%. For sample №2, the CaCO3 content was 24% and the wood content was 36%. As a result of measurements after exposure for 150 days, it was found that the specific impact strength increases by 120%, the bending strength decreases by 60%, and the Shore D hardness decreases by a maximum of 10%. Consequently, decking boards can be confidently used for a long time, since a number of properties almost do not change, but even increase, and some decrease in strength remains within acceptable values.
Beyond Calculation: The Austrian Business Cycle in the Socialist Commonwealth
Authors: DeWeaver Mark
Published: September 2020

This paper extends Austrian business cycle theory to the command economy and demonstrates that Mises’s socialist commonwealth would not be free from Rothbardian error cycles, which J. Guido Hülsmann has argued must originate in “institutions in which the error of many persons is inherent.” Booms and busts are shown to be unavoidable under socialism because (1) the central planner’s incomplete understanding of the opportunity costs associated with any given rate of growth would result in growth targets that are unsustainably high and (2) the planner would be blind to the resulting imbalances until they became sufficiently severe to become “visible” in the statistical data that form her only picture of the world. In this case, Hülsmann’s “erroneous institution” is central planning, which misidentifies the state’s image of the economy with the totality of economic reality.

Mediante la prueba estadística Chi Cuadrado se determinó  que el aula invertida y el aprendizaje en química no poseen relación entre ellas; los docentes afirman en su mayoría haber utilizado el aula invertida en la clase de química; sin embargo, los resultados del nivel de aprendizaje no guardan relación con la aplicación de esta estrategia; en ese sentido se pudo haber desarrollado esta estrategia para la enseñanza de la química, pero no necesariamente se aplicó de forma adecuado, es por eso que los resultados no han sido los esperados, presentándose esta hipótesis como nula al referirse a la relación actual existente entre la aplicación del aula invertida y los resultados de aprendizaje positivos.

Pada saat ini, pembangunan berkembang lebih cepat khususnya pada bidang transportasi salah satunya perkeretaapian. Salah satu sektor yang penting dalam pelayanan kereta api adalah sistem persinyalan kereta api. Sistem ini mengatur lalu lintas perjalanan kereta api yang berfungsi untuk memastikan kelancaran perjalanan kereta api dan menghindari terjadinya kecelakaan.

Saat ini kebanyakan meja pelayanan yang digunakan adalah meja pelayanan jenis Local Control Panel. Namun saat ini sudah ada meja pelayanan berbasis komputer yang umum disebut dengan meja pelayanan jenis visual display unit (VDU). Teknologi saat ini telah berkembang cukup pesat dan banyak ditemukan alat-alat inovasi terbaru sehingga tidak menutup kemungkinan bahwa nanti akan ada pihak yang akan menyalahgunakan hal tersebut. Untuk menangani hal tersebut dibutuhkan pengamanan sistem dari VDU tersebut baik dari data base dan keamanan jaringan yang dipakai.

              Maka dilakukanlah pembuatan sistem security pada VDU yang dapat membantu mengamankan komunkasi VDU yang di implementasikan pada prototype interlocking base compute. Sistem ini dibuat menggunakan metode whitelist, menambahkan ip pada tiap tiap ethernet shield dengan menggunakan telnet dimana ethernet shield sebagai client dan data base sebagai server untuk keamanan tambahan ditambahkanya (secure hash algorithm) SHA 256 pada password untuk tambahan pengamanan komunikasi.

              Dari hasil pengujian terhadap program yang sudah dibuat, dapat diambil kesimpulan bahwa sistem security jaringan ethernet ini dapat membantu mengamankan jaringan komunikasi. Sistem ini hanya dapat digunakan pada prototype interlocking base computer.

Introduction. The only currently available live vaccine against yellow fever (YF) based on chicken embryos infected with an attenuated 17D strain of the YF virus is one of the most effective vaccine preparations. However, the live vaccine is associated with “viscerotropic syndrome” (approximately 0.4 cases per 100 000 vaccinated). Therefore, the development and introduction of highly purified inactivated vaccine against YF is intended to ensure the maximum safety of vaccination against one of the most common human viral diseases.Goals and objectives. Development and evaluation of immunogenicity of the cultural inactivated vaccine against YF at the laboratory model level.Material and methods. Adaptation of 17D strain of YF virus to Vero cell culture, cultivation, removal of cellular DNA, inactivation with β-propiolactone, concentration, chromatographic purification, determination of protein and antigen of YF virus, assessment of immunogenicity in mice in parallel with commercial live vaccine.Results and discussion. Immunogenicity: the determination of specific antibodies of class G (IgG) and virus neutralizing antibodies in the sera of immunized mice showed high level of antibodies exceeding that of immunized with commercial live vaccine. The optimal dose of antigen in the vaccine (total protein) was 50 μg/ml (5 μg/0.1 ml -dose and volume per 1 vaccination of mice). Thus, the laboratory version of cultural inactivated vaccine against YF is as effective (and even superior) as the commercial live vaccine.Conclusion. Laboratory version of cultural inactivated vaccine against YF, which is not inferior in immunogenicity (in animal model) to commercial live vaccine, has been developed.
Semantic number in relation to English language learner awareness
Authors:   Ss. Cyril and Methodius University, North Macedonia, Naumoska Aneta
Published: September 2020

This paper focuses on semantic number in English and its effect on students’ understanding of countability and how they see the world through English. Semantic nominal plurality of reference is not always equivalent to a marked plural noun or S-V plural agreement. The paper aims to explain and illustrate whether morphosyntactic markedness of number coincides with semantic specificity/informativity, and if EFL learners’ worldview shifts depending on their awareness of semantic number. The linguistic issue of number is paired with education, i.e. learners’ development in a foreign language framework. The research was targeted towards English majors (Faculty of Philology, Skopje, N. Macedonia), whose knowledge of number agreement (competence) in English was explored via a questionnaire covering various instances of number inconsistencies. It is noteworthy that most students afterwards stated a rising level of confidence in communicating in English due to a higher level of language accuracy and semantic awareness./ Keywords: semantics, number, agreement, countability, accuracy, EFL, ELT
‘Embedding wellbeing’ in the French language curriculum How to help first year university students develop their perception of learning, motivation and self-efficacy
Authors:   University of Bristol, United Kingdom, Demont Stéphanie , Vailes Fabienne
Published: September 2020

Research carried out by one of the authors shows that when students flourish their positive wellbeing will support their learning, allowing them to engage with the different tasks set and to develop their sense of self-efficacy (Thompson & Vailes 2019, Vailes 2017). This article aims, first, at introducing the concepts of self-efficacy and wellbeing essentials, their relevance, and the urgent need to fully incorporate them as part of the language curriculum. Secondly, we share our experience of creating a new first year French Language curriculum in the School of Modern Languages at the University of Bristol, and, finally, reflect on the findings of the research conducted throughout the 2019-2020 academic year. The curriculum can either support or impair one’s wellbeing depending on whether it does or does not cultivate students’ autonomous motivation and enables students to encounter regular competence, autonomy, relationships and belonging. (Larcombe et al. 2017). Our overall conclusion is that this new approach to the French language curriculum empowers students to develop further confidence in their skills and their ability to learn effectively, thus demonstrating great ‘learning gains’./ Keywords: self-efficacy, wellbeing essentials, embedding wellbeing in the language curriculum, awareness and attitudes, learning gains
Some techniques for teaching business English vocabulary
Authors:   University of National and World Economy Sofia, Bulgaria, Gatev Dilyan
Published: September 2020

The paper focuses on some traditional techniques for vocabulary teaching in the untraditional context of English for specific purposes – business English vocabulary teaching. Those techniques are based on the selection and presentation of collocations, synonyms, antonyms and paronyms, of words whose specialized meaning differs from their general English one, as well as of specialized words with some similarity in meaning, but also with a significant difference. Moreover, attention should be paid to their translation equivalents because learners’ general professional competence is based on the correct use of the respective specialized vocabulary both in the foreign language and the mother tongue. / Keywords: English for specific purposes (ESP), business English, vocabulary teaching and acquisition
Aptidão dos lodos gerados nas Estações de Tratamento de Esgotos no Distrito Federal para condicionamento, utilização e disposição final
Authors: Ferreira Batista Lucilene , Almeida de Souza Marco Antonio
Published: September 2020

O Distrito Federal (DF) possui 16 Estações de Tratamento de Esgotos (ETE) em operação, que empregam tecnologias de tratamento diversificadas e geram diariamente cerca de 300 toneladas de lodo. A presente pesquisa objetivou a caracterização dos processos de produção e tratamento e da qualidade do lodo de esgotos gerado nas ETEs do DF, para identificar as alternativas de disposição final viáveis. Os coeficientes de produção de lodo foram verificados e comparados com a literatura, tendo-se deparado com a dificuldade em se estabelecer um padrão de geração de lodo para a fase de tratamento primário. Foram levantados os requisitos necessários à gestão do lodo, e, com a caracterização dos lodos das ETEs do DF, foi composto um cenário com alternativas que propiciam o aproveitamento do lodo. Concluiu-se que um tratamento complementar simples e de baixo custo para higienização do lodo permitiria sua adequação para o uso agrícola.

Published: September 2020

This research aims to identify Hydro-Power Plant (PLTA) sedimentation in Musi-River, Bengkulu, Indonesia. Based on field

observation and simulation modeling Surface Modeling System 8.01.

High sediment levels cause accumulation of reservoirs and loss of

direct storage, which in turn causes loss of production potential for the Musi Hydro-Power Plant, Bengkulu. The data used in this modeling are bathymetry, current velocity of measurement results, water level, and grain size of sediment. Based on field observations, it was found that basic sediment types were dominated by silt and sand. The highest elevated sediment content values of 0.166 gr/l, current velocity in the upstream was 0.54 - 0.61 m/s while the middle section was 0.43 m/s. After the hydrodynamic model is carried out, then the sedimentation model has values that vary throughout the area model, this is influenced by several factors, one of which is the current movement that can affect the amount of water bottom friction. Volume of sediments obtained in the weirs at the PLTA Musi is 211,588 m3 during the simulation of 1 month if multiplied in 1 year, then it obtained 2539,056 m3. From the results of this research, PLTA Musi must prevent this sedimentation bymaking sediment traps in the upstream.
