Avaliação de Métodos de Mineração de Textos Aplicados à Detecção de Fake News Eleitorais Brasileiras
Authors: Meneses Silva Caio Vinícius , Silva Fontes Raphael , Colaço Júnior Methanias
Published: January 2023

Contexto: A evolução dos meios de comunicação tem contribuído com a disseminação de notícias falsas, principalmente após o surgimento das redes sociais digitais. A velocidade com que estas notícias se espalham tornaram inviável a checagem manual desse imenso volume de dados. Diante deste contexto, trabalhos em diversas áreas têm sido realizados a fim de tentar minimizar os danos causados pela proliferação das denominadas fake news. Objetivo: O objetivo deste trabalho é avaliar a eficácia dos métodos mais utilizados para verificar correspondência de textos, no contexto da detecção de notícias falsas, tendo como base as eleições presidenciais brasileiras de 2018, bem como fazendo um comparativo com os resultados da eleição norte-americana de 2016, publicados na literatura. Adicionalmente, uma visão geral das fakes por seguidores de cada candidato é apresentada. Método: Foi planejado e executado um experimento controlado, para comparar a eficácia dos métodos selecionados. Resultados: Os métodos TF-IDF e BM25 se destacaram nesse contexto, possuindo, estatisticamente e respectivamente, médias similares de Acurácia (79,86% e 79,00%), Precisão (79,97% e 78,76%), Sensibilidade (78,97% e 76,05%) e Medida-F1 (79,47% e 77,38%). Conclusão: A eficácia foi similar à do contexto norte-americano, no qual o BM25 alcançou uma Acurácia de 79,99%. Além disso, considerando o universo de notícias checadas disponível, o período analisado e uma margem de erro de 3,5%, evidenciou-se que houve divulgação de fakes por ambos os lados e que seguidores do candidato Jair Bolsonaro (PSL) foram responsáveis por 62,25% dos tweets relacionados a notícias falsas, contra 37,75% dos seguidores do candidato Fernando Haddad (PT). No que diz respeito às contas excluídas da rede social em um curto espaço de tempo, 59,96% eram de seguidores do candidato do PSL e 40,04% de seguidores do candidato do PT. A divulgação de fake news nem sempre implica intenção, podendo implicar apenas um engajamento maior por parte de alguns seguidores.

Authors: Stoičević Nina , Milosavljević Tamara , Pavlović Jelena
Published: January 2023

Emotional intelligence and health care are closely linked. Empathy is regarded as one of key dimensions of emotional intelligence. The nursing profession has numerous general, but also generic, competencies which requires not only technical knowledge, but also psychological support in everyday work. The aim of this review paper is to point out the importance of assessing the emotional intelligence of nurses on the basis of recent data from the literature. There are many challenges and various sufferings that many health workers are exposed to, especially nurses, which clearly indicates the necessary fact, ie. requires a high degree of emotional skills and competence, because the more complex the job, the more important emotional intelligence. High self-awareness, self-control, the ability to cope with feelings are just some of the competencies that nurses/ technicians should possess. All these characteristics are important factors of emotional intelligence and a basic prerequisite for providing empathy. There are numerous tests and instruments used to assess emotional intelligence.

Computing with concepts using tangible, computational tools
Authors: Christensen Inger-Marie Falgren
Published: January 2023

The computational thinking (CT) method, Computing with concepts using tangible, computational tools, developed for humanistic subjects in higher education, is conceptualised as a 21st century competency in this theoretical article. The method aligns with the categories: Ways of thinking, Ways of working and Tools for working since it helps students build competencies in relation to generating ideas in novel and unconventional ways, in solving problems creatively and rigorously, and in representing and communicating ideas and solutions effectively and computationally. The method helps students engage in constructive dialogue, collaboratively explore abstract concepts and reflect on preferred ways of learning and personal biases, i.e. learn to learn. How CT activities map onto 21st century competencies is influenced by the learning theoretical framing, choice of technology and approach and the function of CT in the activity. The conclusion is that the CT method developed has potential not only as a relevant way for teachers and students in the humanities to work with CT and computational tools but also with respects to supporting students in building 21st century competencies.
Przełamując podziały pomiędzy ochroną pracy i konkurencji, czyli jak chronić uczestników gig economy?
Authors:   Uniwersytet Łódzki, Wiaderek Filip , Wiaderek Zofia ,   Wydział Prawa i Administracji Uniwersytetu Warszawskiego
Published: January 2023

Gig economy to model gospodarczy oparty na działaniu platform pośredniczących pomiędzy osobami zainteresowanymi skorzystaniem z określonej usługi oraz tymi, którzy są gotowi ją świadczyć na żądanie. Rozwój tego modelu jest postrzegany jako jeden z przejawów fragmentacji rynku pracy, w którym upowszechniają się atypowe stosunki zatrudnienia. Związanym z tym zagrożeniem jest prekaryzacja na rynku pracy, która historycznie stanowiła podstawowy problem społeczny towarzyszący powstaniu prawa pracy. Mechanizmem, za pomocą którego można przeciwdziałać negatywnym konsekwencjom społecznym analizowanego zjawiska są rokowania zbiorowe. Dopuszczalność jego zastosowania do uczestników gig economy może jednak rodzić wątpliwości z punktu widzenia zgodności takiego rozwiązania z regułami prawa konkurencji. Z formalnego punktu widzenia uczestnicy gig economy są bowiem zwykle przedsiębiorcami, podobnie z resztą jak zrzeszająca ich platforma. Prawo antymonopolowe ogranicza zaś co do zasady możliwość koordynowania zachowań rynkowych przez przedsiębiorców. Celem rozważań zawartych w artykule rozważań jest przedstawienie opisanego konfl iktu prawa konkurencji i prawa pracy w kontekście pierwotnych założeń systemowych obydwu wymienionych wyżej gałęzi prawa.
“Simplifying” Digital Complexity? A Socio-Technical Perspective. Editorial Introduction to Issue 33 of CSIMQ
Authors: Rajanen Mikko , Ravarini Aurelio
Published: January 2023

This thematic issue of four papers focuses on the importance of a socio-technical perspective in research and practice. A socio-technical perspective sees an organization as a combination of two components – a social and a technical one. The real pattern of behavior in the organization is determined by how well these parts fit each other. While analyzing system problems of getting things done, adequate consideration should be given to technology as well as informal and formal interactions of people with the technology as well as with other people using the technology. The papers in this issue present the sociotechnical perspective as a lens enabling researchers and practitioners to simplify the digital complexity in the socio-technical context.

This article identifies four dimensions in human-technology interaction design ethics and proposes a universal golden rule for human-technology interaction design. To sum up these different aspects of ethical design and the responsibilities of a designer, this position article concludes with a proposed universal golden rule for designing human-technology interactions: Design as easy to use, honest, sustainable, and safe human-technology interactions as you would want others to design for you.
Export competitiveness of milk and dairy products of the Republic of Srpska on the international market
Authors: Mrdalj Mrdalj Vesna , Ostojić Aleksandar , Vaško Željko
Published: January 2023

The aim of this research is an analysis of the export competitiveness of the milk and dairy products of the Republic of Srpska on the international market. Indicators analysed in the paper are the net trade index (NTI) and the index of contribution to the trade balance (CTBI). Additionally, the paper investigates the type of external competitiveness of the milk and dairy products according to four criteria based on a comparison of export and import unit prices. All indicators have been calculated based on statistical data about the foreign trade of milk and dairy products and referred to the period 2015-2021. In the total export structure of the agri-food sector, milk and dairy products have significant participation in an average of 10.40%. CEFTA and EU countries as the major market destinations for milk and dairy products have recorded an average share of 20.30% and 4.81% in the total agri-food export of the Republic of Srpska. Unlike the EU countries, the analysis of the NTI showed the trade of milk and dairy products between the Republic of Srpska and the world as well as the CEFTA countries was competitive. The values calculated for the CTBI indicated positive contribution of milk and dairy products to the trade balance between the Republic of Srpska and the CEFTA countries as well as to the total trade balance. In trade with the EU these products showed comparative disadvantages. The results of the analysis based on the comparison of a unit of export and import prices indicated market segmentation of milk and dairy products into three parts: dominated price competitiveness in the world market, price and quality competitiveness in the CEFTA market, and predominantly price non-competitiveness on the EU market. The analysis of competitiveness type indicates the need for improvement of the export structure of the dairy sector towards favouring higher value-added products, especially on the EU market.

Published: January 2023

Maize production is intensified with a larger amount of mineral fertilizers, which leads to a decrease in micronutrient reserves in the soil. As maize is grown in different regions, research aimed at achieving stable grain yields is very important in the era of climate change. The aim of this study was to determine the influence of zinc application on yield and leaf mass area of three maize genotypes. A three-factorial experiment was performed in the Mačva region. For plant nutrition, 160 kg ha-1 of nitrogen was provided (30 kg ha-1 in basic cultivation, 90 kg ha-1 in pre-sowing, and 40 kg ha-1 in top dressing). Factor A are the years of research in the 2016-2018 period. Factor B: three hybrids ZP 427, ZP 548, and ZP 684. Factor C are different treatments, i.e., Zn0 - control, Zn1 - ZnSO4 25 kg ha-1 was introduced into the soil before sowing, and Zn2 - seed treatment + foliar treatment. For seed treatment before sowing, 63 grains were immersed for 24 h in aqueous ZnSO4 solution (0.129 g and supplemented with 200 ml of water). Sowing was done in the first ten days of April. Foliar treatments were done in the phenophase of 5-7 leaves with 2 l ha-1 liquid fertilizer (7% Zn). The grain yield of hybrids was highly influenced by the year. Treatments and their interactions significantly increased grain yield p0.05. Compared to the control, Zn1 increased grain yield by 14.56% and Zn2 by 14.17%. The ZP 684 hybrid had the highest average yield. Leaf surface was highly influenced by all examined variables and their interactions. In 2018, the leaf surface was on average 3.24% higher than in 2017. The ZP 684 hybrid had the largest leaf surface, 8.30% higher than the ZP 548 hybrid, and 25.10% higher than the ZP 427 hybrid.
Determination of potentially toxic elements in some wild edible and medicinal plants
Authors: Žunić Jovana , Mihajlovic Dijana , Kelečević Biljana , Kovačević Zlatan
Published: January 2023

The aim of this research was to determine the Cu, Ni, Zn, Cd, and Pb contents in the following wild plants: dandelion (Taraxacum officinale Web.), broad-leaved plantain (Plantago major L.), and ribwort plantain (Plantago lanceolata L.) collected from the natural environment at three different locations in the north of the Republic of Srpska, in the surroundings of Banja Luka (two localities) and Doboj (one locality). The examined species represent wild edible and medical plants, most commonly used in folk medicine. Plant material and associated soils were air-dried, acid digested, and analyzed by atomic absorption spectrometry (AAS). The results have shown the highest Zn contents in all examined plants, which were followed by the contents of other determined biogenic elements (Ni and Cu), while contents of toxic elements (Pb and Cd) were noticeably lower. The contents of potentially toxic elements determined in the plants were lower than recommended limits of toxicity, with the exception of the location L3-Stanari where elevated Ni contents were found in all examined plants and the associated soil. This implies an evident risk in case of consumption of the plants grown at this location and the need for further investigation in order to establish the exact degree of contamination and to implement proper activities.

Published: January 2023

Austropotamobius torrentium (Schrank, 1803) lives in two watercourses, namely Subotica (Sana) and Toplik (Tilava). The influence of the ecological conditions of these rivers on individuals of this species is analyzed based on 22 morphometric parameters. The assessment of abiotic conditions was done through the measurement of physical and chemical water parameters and the analysis of the composition of phytobenthos and macrozoobenthos. Sampling was carried out in June, September, and October 2021. Water quality at the investigated localities (on the basis of abiotic and biotic parameters) is oligo to betamesosaprobic. A total of 37 crayfish were analyzed (20 from Subotica and 17 from Toplik). Female crayfish have shown significant differences in the head width (HEW) and abdominal thickness (ABH). Males differed significantly in a number of parameters, including the weight (W), head shape (HEL and HEW), rostrum length (ROL), carapace width (CPW), and abdominal shape (ABH and ABL). Higher values of the indicated parameters have been found in the males from the Subotica River. The obtained results are influenced by different ecological conditions of their habitats. The Subotica River is a larger watercourse in the lowland belt with a large number of microhabitats, and the Toplik is a small river in the mountain belt, with uniform sediment and a small number of ecological niches of the analyzed species. The general ecological conditions in the water of both watercourses are also affected by aquaculture facilities, where wastewater has a direct influence on the distribution of Austropotamobius torrentium individuals in the watercourses of the Subotica and Toplik Rivers. For more detailed and complete data, it is necessary to analyze a larger number of individuals in both populations, and to include additional morphometric-meristic parameters and molecular-genetic analyses.

Authors: Velamala Ranga Rao , Pant Pawan Kumar
Published: January 2023

SFMToolbox is an ArcGIS Python toolbox developed in ArcGIS Desktop (ArcMap) to perform preprocessing tasks for the automatic creation of maps of soil fertility parameters. Through SFMToolbox, users can automatically produce 12 soil fertility parameter maps as a batch at one time. It is easy to use, where users can only provide input; the output files are automatically created from the name of the sample point and saved in the defined workspace. During the execution of the tools, various processes, such as Inverse Distance Weighted (IDW) – a technique of interpolation, reclassification, adding color, merging, projection, area calculation, and legend are done automatically for all12 parameters at the same time. The SFMToolbox was validated as part of the following case study: village – Kashipur, tehsil – Balrampur, district – Balrampur, state – Uttar Pradesh, Country – India. The results show that the user can quickly generate maps and save time, improve accuracy, and reduce human intervention and ensure uniformity among maps. This toolbox also applied to Cycle II data from the Government of India’s Soil Health Card (SHC) scheme and timely produced 12-parameters soil nutrient maps for 630 districts in a uniform format. The toolbox may be used by public and private organizations to make timely decisions on agricultural and environmental issues.

Long non-coding RNAs (lncRNAs) have emerged as fundamental regulators in various biological processes, including embryonic development and cellular differentiation. Despite much progress over the past decade, the genome-wide annotation of lncRNAs remains incomplete and many known non-coding loci are still poorly characterized. Here, we report the discovery of a previously unannotated lncRNA that is transcribed 230 kb upstream of the SOX17 gene and located within the same topologically associating domain. We termed it T-REX17 (Transcript Regulating Endoderm and activated by soX17) and show that it is induced following SOX17 activation but its expression is more tightly restricted to early definitive endoderm. Loss of T-REX17 affects crucial functions independent of SOX17 and leads to an aberrant endodermal transcriptome, signaling pathway deregulation and epithelial to mesenchymal transition defects. Consequently, cells lacking the lncRNA cannot further differentiate into more mature endodermal cell types. Taken together, our study identified and characterized T-REX17 as a transiently expressed and essential non-coding regulator in early human endoderm differentiation.
Pericytes control vascular stability and auditory spiral ganglion neuron survival
Authors: Zhang Yunpei , Neng Lingling , Sharma Kushal , Hou Zhiqiang , Johnson Anatasiya , Song Junha , Dabdoub Alain , Shi Xiaorui
Published: January 2023

The inner ear has a rich population of pericytes, a multi-functional mural cell essential for sensory hair cell heath and normal hearing. However, the mechanics of how pericytes contribute to the homeostasis of the auditory vascular-neuronal complex in the spiral ganglion are not yet known. In this study, using an inducible and conditional pericyte depletion mouse (PDGFRB-CreERT2; ROSA26iDTR) model, we demonstrate, for the first time, that pericyte depletion causes loss of vascular volume and spiral ganglion neurons (SGNs) and adversely affects hearing sensitivity. Using an in vitro trans-well co-culture system, we show pericytes markedly promote neurite and vascular branch growth in neonatal SGN explants and adult SGNs. The pericyte-controlled neural growth is strongly mediated by pericyte-released exosomes containing vascular endothelial growth factor-A (VEGF-A). Treatment of neonatal SGN explants or adult SGNs with pericyte-derived exosomes significantly enhances angiogenesis, SGN survival, and neurite growth, all of which were inhibited by a selective blocker of VEGF receptor 2 (Flk1). Our study demonstrates that pericytes in the adult ear are critical for vascular stability and SGN health. Cross-talk between pericytes and SGNs via exosomes is essential for neuronal and vascular health and normal hearing.

Background

Continuous cultivation of ginseng crops in fixed plots can lead to disease outbreaks, yield losses and replanting failures. Fallow periods can help restore soil health and increase the sustainability of agricultural systems; however, taking land out of production for extended periods is often not feasible. Short-term fallow periods could restore soil health, but few studies have examined the effects of short-term fallow treatment on the health of soil in ginseng fields.

Methods

In this preliminary study, we used metagenomic analysis to assess changes in the abundance of major ginseng pathogens and soil health overall following a short-term fallow period in a region in the Changbai Mountains. A sample from a forest plot (Hx0ks), was compared to a sample from a field where ginseng was previously cultivated and then had been left fallow for two years (Hx2), and a sample from a field that had been fallow for two years and was subsequently replanted with ginseng (Clsd).

Results

Soil that was fallow for two years, and then replanted with ginseng, showed reduced nutrient content and lower diversity of soil bacterial and fungal communities than soil that remained fallow. Candidatus Solibacter (5%) and Rhizomicrobium (3%) were the most abudant bacterial genera in Hx2. Rhizomicrobium (4%) and Gemmatimonas (3%) were the most abundant bacterial genera in Clsd. Mortierella (22%) and Peziza (12%) dominated the fungal community in Hx2. Lecanicillium (38%) and Mortierella (13%) dominated the fungal community in Clsd. Fallow periods also increased the functional diversity of soil as predicted by PICRUSt and decreased the relative abundance of the pathogenic fungi.

Conclusions

Preliminary findings were consistent with the hypothesis that fallow management in ginseng cultivation can improve soil microbial community structure and function and reduces the number of plant pathogens; however, testing this hypothesis will require replicated plots.

The pace of growth across social media sites is something to be astounded at. The constantly evolving digital media environment is changing the mechanisms of political action and social transformation in many societies. This study entitled, Beyond the Hashtags: Constructs of Political Science Students on Social Media as a Form of Justice had its purpose to answer these two questions the constructs of Political Science students on social media as a form of justice and its effects to the perspectives of Political Science students on the concept of justice. The study implored a qualitative method using phenomenological study as its research design. It had utilized interview guide as its research instrument and a one-on-one interview for its data gathering. Also, thematic analysis was used in the study for the data analysis. The findings of this research concluded that the perceptions of the Political Science students vary and could hold alike or different explanation from one another; therefore, it is guaranteed that participants would have different standpoints, and those who hold the same could be alike but the explanations underlying them may differ. Given the diversified answers, as a result, the researchers have verified that social media cannot be a form of justice but can also be used to propagate information and awareness. It also reduces the ignorance of netizens when it comes to the occurrences of the country and around the world. People on social media could also understand the story of both sides and weigh what is right and wrong, distinguishing what is true and not. Social media is a tool in which people can convey their feelings and experiences. It’s an outlet for human behavior and public concern, but it is not enough to secure justice for those who seek it.

Introduction: Nigerian FARO 40 rice starch has been underutilized due to low edible qualities. The aim of this study was to chemically modify underutilized rice variety using standard methods for possible use as pharmaceutical grade starch.

Methodology: The physicochemical properties of native and phosphorylated FARO 40 rice starch were analysed using standard methods. Scan electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), Thermogravimetric analyser and Derivative Thermogravimetric analyser were utilized to decide the morphological properties of native and modified starch. The comparative binding and disintegrant capacities of these starch in tablets detailing were examined utilizing paracetamol as model sedate. Paracetamol tablets were defined using wet granulation strategy and direct compression utilizing native starch, acetylated starch, and phosphorylated starch as binders. The tablet features such as smashing quality, friability, crumbling time and disintegration test were assessed utilizing friabilitor machine, deterioration machine and disintegration device.

Results: The results showed significant decreased (P<0.05) values in pH, moisture content, and gelatinization temperature for modified starches compared to the native starch. Significant increase observed in ash content, solubility, swelling capacity, browning temperature, charring temperature and amylose content of phosphorylated starch as compared to the native starch. Furthermore, significant changes were also observed in morphology of the phosphorylated starch compared to the native rice starch. The weight, crushing strength, friability, disintegration time and dissolution profile values for paracetamol tablets formulated with the phosphorylated starch were within the standard specified by British pharmacopeia and were significantly different from that of native starch (P<0.05).

Conclusion: Chemical modification has shown to improve the physicochemical and morphological properties of the three FARO 40 underutilized Nigerian rice varieties for pharmaceutical purpose.

This study was carried out to assess the influence of post-mortem processing methods on quality and shelf life of two breeds of sheep meat.  A total of twelve sheep, six each from Balami and Ouda (two prominent breed of Sheep in Nigeria) were weighed, slaughtered and allotted to three processing methods which are scalding, singeing and skinning in a completely randomized experimental design in a 2 × 3 factorial arrangement (2 breeds and 3 post-mortem processing methods). The carcass characteristics, primal cuts, physico-chemical properties, sensory and microbial counts were assessed. The results showed that Ouda breed gave the highest (p<0.05) dressing % (36.43%), preferred (p<0.05) primal cuts in rounds (15.13%), Marbling score, lipid profile (Total cholesterol, LDL), and Lipid peroxidation, Balami sheep was however rated higher (p<0.05) in juiciness, tenderness and overall acceptability. The Scalded sheep had the highest dressing % (35.45%), with preferred marbling score (5.80), and microbial counts. The scalded samples were also the lowest (p<0.05) for crude Fiber, CF, total cholesterol (276.40 mg/dL) and LDL (183.89 mg/dL). Minimal exudate loses (cooking loss and drip loss) were recorded in singeing samples and was rated highest (p<0.05) with organoleptic properties. The microbial and fungi loads increased with the storage days. Conclusively, Ouda breed and Scalding method of post-mortem dressing gave the preferred values for optimum nutrients and shelf-life of sheep meat.

Aims: To comparatively evaluate the efficiency of three simple trichomoniasis diagnostic techniques in a low-resource setting at the Baixada Fluminense region, Province of Rio de Janeiro, Brazil.

Place and Duration of Study: The sample was obtained from the medical records of women attending the Iguaçu University Clinic's Gynaecology Outpatient Clinic from January to December 2020. The sample consisted of medical records of 135 women aged 17 to 78 years.

Methodology: With the aid of a sterile and disposable bi-valve speculum, vaginal secretion was collected with a swab from the vaginal sac. The secretion was used for smears in two slides for wet mount examination and Papanicolaou staining and then seeded in a tube with 6 ml of Diamond's culture medium.

Results: The results showed that among the 135 women with clinical signs of vulvovaginitis, 65 (48.15%) were infected by Trichomonas vaginalis. The positivity rates displayed significant differences according to the detection methods used. Wet mount examination and Papanicolaou exams were less efficient, detecting only 7.7% of total infections confirmed by the culture in Diamond's medium.

Conclusion: The analysis of the results allowed an update in the detection protocol of Trichomonas vaginalis infections in the Gynaecology Outpatient Clinic of the Iguaçu University. Papanicolaou test was eliminated from the protocol since it requires more resources than the wet mount examination. Wet mount examination was maintained because it detects part of the Trichomonas vaginalis infections at the time of medical attending, following the core principle of the syndromic approach indicated by WHO, but with greater efficacy than the diagnostic determination based on signs and symptoms. Culture by Diamond’s medium proved to be one of the best options for low-resource settings when compared to other detection methods of T. vaginalis analyzed in the current scientific literature, with an acceptable detection rate, only lower than sophisticated and high-cost methods.
