A RELAÇÃO ENTRE LUCRO BRUTO, LUCRO OPERACIONAL E LUCRO LÍQUIDO E OS RETORNOS FUTUROS NO BRASIL
Authors: Francisco Alysson , Caio Galdi Fernando 
Published: November 2022

Objetivo: O objetivo desse trabalho foi verificar qual das definições de lucro (lucro bruto, lucro operacional ou lucro líquido) tem melhor desempenho em explicar o comportamento futuro dos retornos no mercado brasileiro, e se esses resultados se mantêm ao se formar carteiras combinando a rentabilidade, índices book-to-market e BrF_Score.
Método: Para tal, são utilizadas as regressões de dois estágios de Fama e MacBeth, o teste T2 de Hotelling e o modelo de três fatores de Fama e French, além da análise do excesso de retorno das carteiras construídas. A periodicidade do estudo é mensal, abrangendo o período de janeiro de 2010 até junho de 2019, totalizando 15.577 observações de 200 empresas.
Resultados: Os resultados demonstram que o lucro líquido e o lucro operacional produzem as métricas de rentabilidade com os maiores poderes explicativos para o retorno de um mês à frente, além de produzirem as carteiras com maiores excessos de retorno, se comparadas às métricas de rentabilidade baseadas no lucro bruto. Contribuições: Portanto, a contribuição do trabalho foi demonstrar que o lucro líquido explica melhor o retorno futuro no mercado brasileiro, enquanto no mercado americano, existem evidências de que o lucro bruto desempenha este papel, e essas diferenças se dão pelas diferentes influências macroeconômicas sofridas por tais mercados.
Quasi-synchronous discussions: A proposal to measure the effect of Teams on cooperation, belonging, emotion and interactions

Published: November 2022

As students begin to reconnect after the COVID-19 pandemic, changing student expectations around online engagement seem to be suggesting that new approaches should be adopted. Recent research has found that students who engaged with each other in a discussion task in a synchronous mode were more willing to work together, felt more positive and more like they belonged than students in an asynchronous mode. We wish to extend these findings by investigating whether Microsoft Teams promotes a quasi-synchronous mode of discussion and has a similar beneficial effect. The proposed study adopts a mixed-methods approach of quasi-experimental design to address this question. Students will be randomly assigned to groups of five and provided with online forums (control) then re-form and use Teams (experimental) for a discussion task. Data will be collected through survey, digital artefacts and interviews. We aim to contribute robust, empirical evidence on the effects of Teams on student engagement, which will be of interest to educational leaders and teachers.
Navigating the third space: the online community mentoring program
Authors: McNally Clare , Heggart Keith , Kelly Oriel , Arumugam Puva , Murray Fiona 
Published: November 2022

Professional and academic staff with a focus on learning and technology are both increasingly present in Australasian universities and seen as vitally important in the delivery of high-quality learning experiences. These professional staff often have titles such as learning designers, technology integrators, educational designers and similar. Yet their precise position and role within higher education, and indeed, the requisite skills and knowledge required to successfully perform these roles often remains vague, especially for academic staff with whom they work. These roles became even more important during the disruption caused by the COVID-19 pandemic (McIntosh & Nutt, 2022).
These staff often work in what is described as the “third space” (Whitchurch, 2008), a hybridized zone that requires an understanding of different types of learning programs, and ways in which these can be delivered most effectively in a virtual environment (Zellweger, Moser & Bachmann, 2010). In this way, they are boundary crossers (Watermeyer, Crick & Knight, 2021) between the academic and professional spaces, required to work within both, but belonging to neither. This can often contribute to feelings of professional isolation amongst these staff, as well as a lack of clarity about career progression.
Mentoring is recognised as an avenue for welcoming new members of the profession. It combines more experienced members with less experienced members and takes the form of regular meetings to discuss challenges and opportunities (Bean & Hyers, 2014; Donelly & Mcsweeney, 2010). The online variant is hardly new, although it has grown significantly during the pandemic (Joseph, Lahiri-Roy & Bunn, 2022). It offers advantages in terms of reach and scalability to participants, although there are potential weaknesses, too. Traditionally, mentoring is an activity that takes place between one mentor and one protégé. However, group mentoring is on the increase.
This presentation reports on how a group approach taken in a community mentoring program (CMP) comprised of five staff from different universities (three mentors and two mentees) provided an avenue for third space staff to share their experiences with each other in order to begin formulating a collective professional identity. Group mentoring allowed a greater diversity of experiences and ideas, which in turn contributed to a greater feeling of ‘being in it together’. The CMP became a space for the exploration and discussion of different roles within higher education, as well as the sharing of common experiences, successes and frustrations. Our reflections may inspire you to create a similar opportunity within your own institutions, or through the ASCILITE Mentoring Program.

Abstract

Physalis alkekengi L. (Solanaceae) is encountered in different regions of Bulgaria as a wild growing or ornamental plant. The objective of this work was to characterize the phytochemical composition (macro and micro components) of the leaves and stems of two local phenotypes (PA-SB and PA-NB), with the view of revealing their use potential. The dry leaves contained (DW) protein (16.25 and 19.27%), cellulose (25.16 and 25.31%), and ash (18.28 and 16.16%) and the stems contained protein (6.83 and 7.35%), cellulose (39.34 and 38.25%), and ash (15.01 and 7.48%) for PA-SB and PA-NB, respectively. The dominant amino acids (by HPLC) in the leaves of both phenotypes were arginine (21.3–22.3 mg/g) and aspartic acid (8.8–18.4 mg/g), and those in the stems were proline and aspartic acid for PA-SB (8.8, 7.7 mg/g); isoleucine and tyrosine for PA-NB (12.8, 6.6 mg/g). Mineral elements, determined by AAS (K, Ca, Mg, Na, Cu, Fe, Zn, Mn, Pb, Cr), also varied between phenotypes and plant parts. The leaves alone were further processed by extraction with n-hexane, for the identification of leaf volatiles (by gas chromatography-mass spectrometry). The analysis identified 28 components (97.99%) in the leaf extract of PA-SB and 32 components (97.50%) in that of PA-NB. The volatile profile of PA-SB leaves was dominated by diterpenes (49.96%) and oxygenated sesquiterpenes (35.61%), while that of PA-NB was dominated by oxygenated aliphatics (40.01%) and diterpenes (35.19%). To the best of our knowledge, the study provides the first data about the phytochemical composition of the leaves and stems of P. alkekengi from Bulgaria, in a direct comparison of phenotypes from two distinct wild populations, which could be of further scientific interest.

Published: November 2022

AbstractThe antioxidant potential of various extracts was evaluated using different antioxidant assays such as 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay, ferric reducing antioxidant power (FRAP) assay, and 2,2-azinobis-ethylbenzothiozoline-6-sulphonic acid (ABTS) using UV spectrophotometer. The highest absorbance was observed in ethanolic extracts (EEs) ofEuphrasia stricta71.92 ± 1.22%, 65.77 ± 1.38%, and 67.88 ± 0.74%, followed by methanolic extracts (MEs) 70.14 ± 0.82%, 64.84 ± 0.74%, and 65.48 ± 1.40% for DPPH assay (517 nm), FRAP assay (700 nm), and ABTS assay (734 nm), respectively. The EEs ofEuphorbia platyphyllosL. showed the antioxidant activity of 69.76 ± 1.48%, 64.42 ± 0.88%, and 65.54 ± 1.36% and MEs 68.00 ± 1.50%, 62.92 ± 0.64%, and 63.42 ± 0.94% for DPPH, FRAP, and ABTS assays, respectively. So, this research suggested that these medicinal plants possess a significant antioxidant potential and are important source of natural antioxidants and can be effectively used in treating oxidative stress disorders.

AbstractThe objective of the current study was to examine the phytochemical andin vitrothrombolytic, anti-arthritic, anthelmintic, and insecticidal effects ofTrewia nudiflora(TN) methanolic leaf extract with its methanol (MTN), chloroform (CTN), and ethyl acetate (ETN) fractions.Pheretima posthumaandTribolium castaneumwere employed for evaluating the antihelmintic and insecticidal properties, respectively. All the tested extracts showed the presence of copious potential constituents in phytochemical analysis. Among all extracts, MTN extract exhibited the utmost clot lysis (35.95 ± 4.81%) property compared to standard streptokinase (SK) (53.77 ± 7.52%). All samples displayed striking protein denaturation activity in a dose-dependent manner (100–500 µg/mL), where the highest inhibition was observed for MTN (67.26 ± 6.39% at 500 µg/mL). Each extract demonstrated considerable anthelmintic activity at 25–75 mg/mL dose ranges. ETN showed the strongest anthelmintic activity at the highest dose. Among all samples, the CTN extract displayed the utmost mortality rate (77.22%) in the insecticidal test. The results of the study suggest thatT. nudifloraleaf extracts may have potential against thrombosis, arthritis, helminths, and insects, which warrants the necessity of extensive isolation and identification of bioactive compounds to develop newer effective drugs upon preclinical and clinical investigations.
Thermal stability and optical properties of radiation-induced grafting of methyl methacrylate onto low-density polyethylene in a solvent system containing pyridine
Authors: Al-Gahtany Samera Ali 
Published: November 2022

Abstract
In this study, the grafting of methyl methacrylate (MMA) in a solvent system containing nitrogen of pyridine onto LDPE films was performed using the post-irradiation technique in nitrogen at different gamma doses. The DG% obtained in MMA grafting was 71.0% at 10 kGy of γ dose was increased to 90% in (MMA/Py) (80/20 v/v%) system, indicating the existence of Py enhancement in the grafting % of MMA. The addition of pyridine (Py) into MMA matrix increases the molecular weight of the matrix due to the plasticizing effect of Py on the system. Morphological and structural changes in optical properties and thermogravimetric analysis were performed for the films. According to Fourier transform infrared data, a reaction may be placed between Py and MMA molecules. Furthermore, the effect of Py molecules on the optical properties of LDPE films is studied. The optical transition upon the grafting process increased, indicating the movement of the electrons due to intramolecular hydrogen bonds between MMA and Py molecules. The Urbach energy and the optical band gab, E
g, were investigated and found to depend mainly on the grafting degree. The results obtained from E
g calculations recommended using an irradiation dose of 15 kGy to get LDPE-g-MMA/Py films with suitable optical properties.
The EU Taxonomy’s (Potential) Effects on the Banking Sector and Bank Lending to Firms
Authors: Kirschenmann Karolin 
Published: November 2022

Abstract
One of the key pillars of the European Green Deal is a renewed sustainable finance strategy to finance sustainable growth and to channel private investments towards projects that support the transition to a climate-neutral economy. The aim of this policy is to make the private sector take into account sustainability-related non-financial factors when making financing and investment decisions. Within this framework, the EU Taxonomy provides a uniform definition and classification system of environmentally sustainable economic activities. In addition, the EU Taxonomy itself provides the basis for further legislation and regulation. Banks as the main financiers of firms in Europe and therefore important players in directing capital flows towards sustainable projects are thus targeted with several requirements based on the Taxonomy. The question then is how banks’ lending to firms is affected by these regulatory changes and whether an impact on the greening of firms’ economic activities can be achieved. The existing literature provides evidence that firms’ environmental, social and governance (ESG) risks, profiles and performance influence their loan conditions, but it is unclear whether better funding conditions lead to reduced carbon emissions or “greener” activities at the firm level.
Study on water regime assessment and prediction of stream flow based on an improved RVA

Published: November 2022

Abstract
Considering that many hydrological analysis methods compare and analyze the runoff before and after the construction of the reservoir, without restoring the measured data of the hydrological station, in this case, when the length of the measured data series is short, the evaluation results will be affected. In this article, based on the runoff reduction of stations affected by water conservancy projects, an improved range of variability approach (RVA) which can be applied to 1-year hydrological change analysis is proposed by coupling the hydrological variation index with the appropriate upper and lower limit theory of RVA. As Jialing river watershed is selected as the research area, the runoff depth of Beibei station is reduced, and then the improved RVA is employed to analyze the degree of change in river water regime. It is concluded that the change degree of overall hydrological index in Beibei station is high, and the prediction of variation of water regime of Beibei station can be made with the aid of simulating the operation of cascade reservoirs, with the inflow of Beibei station in flood season to reduce, and the inflow in dry season to increase. The example verifies the effectiveness of the improved RVA method, and the analysis results can provide a reference for the adjustment of the operation mode of upstream cascade reservoirs.

Published: November 2022

Abstract
The article provides a comparative analysis of sunflower seed production in Ukraine, the EU and globally for the period from 2000 to 2021. The Ukraine’s share in the world sunflower production was found and analyzed. The analysis of the gross collection of sunflower seeds in the regions of Ukraine for two conditional periods (2000–2010 and 2011–2021) was carried out. Thus, during the researched period, the average yield increased from 1.04 t/ha in 2000 to 2.57 in 2021, i.e. by 2.5 times. It became possible due to the improvement and adaptation of cultivation technology and careful selection of sunflower hybrids that are better adapted to climatic changes. It was determined that the change in climatic conditions has affected the zones of comfortable sunflower cultivation in Ukraine. According to the yield index, during the first conditional period the central regions of Ukraine were in the lead (1.57 t/ha), and during the second period, the northwest regions of the country stepped up (2.83 t/ha). The above data suggest that the gradual change in sunflower cultivation technology and the search for new drought-resistant crop hybrids give hope that Ukraine will maintain its position in the world as a leader in the export of sunflower oil.

Ideologie im Wörterbuch. Beispiele aus deutscher und romanischer Sicht
Authors: Schweickard Wolfgang 
Published: November 2022

Abstract
Dictionaries are only marginally involved in the formation of ideologies. However, they reflect the values that are typical of individual epochs, and help to consolidate and spread ideological concepts. The analysis of dictionaries therefore has considerable heuristic potential for illustrating different forms of ideologies in their linguistic expression. The present paper exemplarily sheds light on the relationship of ideology and lexicography from a German and Romance point of view. It starts with 17th-century academy dictionaries, which mirror the elitist social realities of the time, and goes on with reflections on taboo vocabulary, feminine job titles and the lexical influence of English on French.
Sprachtransgressionen
Authors: Bär Jochen A. 
Published: November 2022

Abstract
Der Beitrag befasst sich mit der bekannten, aber bislang zu wenig reflektierten Tatsache, dass Diskurse in unterschiedlichen Sprachen nicht nur parallel geführt werden, sondern sich vielfach überlagern und beeinflussen. Derartige Überlagerungen und Beeinflussungen, die zudem auch noch zwischen unterschiedlichen Zeichenmodalitäten – z.B. Wort und Bild – zu beobachten sind, stellen Interpretabilien eigener Qualität dar, für die spezielle semantische Beschreibungsansätze zu entwickeln sind. Am Beispiel eines konzeptographischen Forschungsprojekts zum literatur- und kunsttheoretischen Diskurs des späteren 18. und früheren 19. Jahrhunderts werden diese Ansätze erörtert.

Published: November 2022

Abstract
Wearable and movable lodged health monitoring gadgets, micro-sensors, human system locating gadgets, and other gadgets started to appear as low-power communication mechanisms and microelectronics mechanisms grew in popularity. More people are interested in energy capture technology, which turns the energy created by motion technology into electric energy. To understand the difference in motor skill levels, a nonlinear feature-oriented method was proposed. A bi-stable magnetic-coupled piezoelectric cantilever was designed to detect the horizontal difference of motion technology. The horizontal difference was increased by the acceleration generated by the oscillation of the leg and the impression betwixt the leg and the ground during the movement. Based on the Hamiltonian principle and motion technique signal, a nonlinear dynamic model for energy capture in motion technique is established. According to the shaking features of human leg motion, a moveable nonlinear shaking energy-gaining system was the layout, which realized the dynamic characteristics of straight, nonlinear, mono-stable, and bi-stable. The experimental outcome shows that nonlinearity can effectively detect the difference of motion techniques. The experimental results of different human movement states confirm the benefits of the uncertain bi-stable human power capture mechanism and the effectiveness of the electromechanical combining design established. The nonlinear mono-stable beam moves in the same way as the straight mono-stable beam in the assessment, but owing to its higher stiffness, its frequency concentration range (13.85 Hz) is moved to the right compared to the linear mono-stable beam, and the displacement of the cantilever beam is reduced. If the velocity is 8 km/h, the mean energy of the bi-stable method extends to the utmost value of 23.2 μW. It is proved that the nonlinear method can understand the difference in the level of motion technique effectively.

A comparative study of multi-modal metaphors in food advertisements
Authors: Kou Guirong , Liang Yuan 
Published: November 2022

AbstractMulti-modal metaphor is a new perspective in metaphor research developed in modern times. Beyond the metaphor research of language, it combines text, image, sound, and other modes and provides new insights and perspectives for metaphor research. Food advertisements often combine sound, images, and other forms to promote the products and increase consumers’ desire to buy, and they often contain metaphors of multiple modes. However, under the perspective of cross-cultural research, when the same food brand is advertised in different countries, the multi-modal metaphors are varied to appeal to different audiences. This article compares food advertisements in China and in the U.S. from the perspective of multi-modal metaphors, and analyzes the varied applications arising from different cultural influences. The research may act as a reference for advertising strategies on cross-cultural occasions.
