Authors: Sayyad Ramejabi Jahangir , Gadale Sharda R.
Published: March 2022

Organic dyes effluents are a foremost source of environmental pollution and hence its removal has become an important area of research these days. A series of different concentrations of Lanthanum- Molybdenum Oxide catalysts, LMO (1%, 5%, 10%, 15% and 20wt.%) were prepared by a sol gel method and calcined at 500°C. Thus, synthesized LMO catalysts were characterized by Powder X-ray diffraction analysis (XRD), Flame Emission scanning electron microscopy (FESEM,) Energy-dispersed X-ray analysis (EDX), RAMAN Spectroscopy and Thermo-gravimetric analysis (TGA). The photocatalytic properties of LMO nanoparticles were investigated via methyl orange (MO) and bromothymol blue (BTB) as a model organic compound in aqueous solution under visible light irradiation. More than 80% and 60% degradation of MO and BTB dye within 150 minutes indicating the excellent photocatalytic activity of as prepared catalysts.
IN-VITRO ANTIMICROBIAL ACTIVITY OF ETHYL ACETATE EXTRACT OF CENTAUREA BEHEN LINN
Authors: Gupta Neesha , Kalaiselvan A.
Published: March 2022

This work aims to evaluate the antimicrobial potential of ethyl acetate extracts of Centaurea Behen Linn (C. Behen) on some microorganisms. Agar well diffusion method has been used to determine the antimicrobial activities of plant extracts against Gram-positive bacteria, Gram-negative bacteria (Streptococcus mutans, Staphylococcus aureus, Salmonella bongori and Escherichia coli), and two fungus (Candida albicans and Aspergillus niger). The extracts exhibited both antibacterial and antifungal activities against tested microorganisms using standard ofloxacin, ciprofloxacin and fluconazole (10-30μg/ml). The antimicrobial activity was determined by measuring the diameter of the zone of inhibition in term of millimeter (mm). To analyze the antimicrobial activity, ethyl acetate extract of C. Behen was tested by well diffusion method against six selected strain and which shows significant inhibitory action against all the tested strain. The antimicrobial activity of ethyl acetate extract of root against all microorganisms was concentration dependent but less than standard drug. It is concluded that the antimicrobial activity showed by the plant is due to the presence of phytochemicals. For future studies, phytochemcials responsible for these activities can be isolated and modified for pharmacological purpose.

Authors: Vidya V. R. , Pillai Padmesh , Preetha T. S.
Published: March 2022

Kaempferia galanga L. is a pharmaceutically and traditionally important medicinal plant. Its rhizomes are having potential demand in ayurvedic drug preparation. The study presented here reports the essential oil components analysed using GC-MS in three samples of K. galanga such as the microrhizomes raised through tissue culture technique, the mini rhizomes harvested from the field transferred tissue culture-derived plants and the mother rhizomes, which are the stock plants (control). Potent bioactive compounds like ethyl-p-methoxycinnamate, ethyl cinnamate, borneol and pentadecane were detected in the samples. The amount ethyl p- methoxycinnamate was very high in microrhizome (58.088%) and minirhizome oil (31.24%) as compared to in vivo mother rhizome. The amount of ethlyl cinnamate was 9.21% in microrhizome oil and it increased to 39.42% in minirhizome oil. Pentadecane recorded 1.482% in microrhizome and its amount increased to 4.49% in minirhizome oil, while the amount was noticed in in vivo mother rhizome. Borneol was analysed from micro (1.349%) and minirhizome oil (3.57%) samples but it was absent in mother rhizome. In our study, in vitro microrhizome and minirhizomes essential oil depicted superior quality in terms of the bioactive compounds and was on par with the mother rhizome oil. The in vitro production methodology developed here would help in the large scale production of pharmacologically important components from K. galanga.
POLY (N-VINYLCARBAZOLE) AND (α-POLMETHYLSTYRENE) BASED SEMI INTERPENETRATING POLYMER NETWORK: SYNTHESIS AND CHARACTERIZATION
Authors: Mishra Dayanand , Kamal Meet
Published: March 2022

A series of interpenetrating polymer network (IPN) based on poly(N-vinylcarbazole) and poly(α-methylstyrene) were synthesized using benzoylperoxide (BPO) as initiator and divinyl benzene as crosslinker. The IPNs were characterized using infrared spectroscopic technique, differential scanning calorimetric analysis, thermal gravimetric analysis and scanning electron microscope techniques. FTIR spectra of the synthesized polymeric network revealed the band positions for poly(N-vinylcarbazole), at 2923 cm-1, 1600 cm-1 and 1629 cm-1, and for poly(α-methylstyrene) at 3019 cm-1, 1484 cm-1, 707 cm-1 and 1451 cm-1. The relatively shortened peak value (1595 cm-1 CH-CH2-) of vinyl group in poly(α- methylsytrene) justify the disappearance of double bond which is a clear indication of bonding between the two polymer networks leading to IPN formation. The differential scanning calorimetry (DSC) graph showed glass transition temperature (Tg) at 449ºC, which indicate crystalline nature of synthesized IPN. Thermogravimetric analysis (TGA) graph showed thermal stability of IPN upto 395ºC. Fluorescence spectra of IPN at the visual range near 450 nanometer also predicts its good optical properties. The SEM image showed a transparent and dual morphology of the synthesized polymeric network. The properties like percentage swelling, average molecular weight (Mc) between crosslinker are in direct function of initiator (benzoyl peroxide) and poly(N-vinyl carbazole) but inverse function of monomer (α- methylsytrene) and crosslinker (divinyl benzene).

Authors: Taj M. Yasmin , Mohan E.
Published: March 2022

Biofertilizers are cheap, eco-friendly, improve soil fertility and plant nutrition within short time, and are effective components in organic farming. The present field study was carried with eight treatments to study the effect of Azospirillum, Phosphobacterium and AM fungus and their combination on primary growth characters coriander. The experiment was conducted in a factorial randomized block design. The collar diameter, plant height and number of leaves were significantly more in treatment with combined inoculation of Azospirillum + Phosphobacterium + AM fungus (T7) than control (T0). The increase in primary growth parameters in treatments with biofertilizers may be due to enhance the uptake of nitrogen, phosphorous and other essential nutrients for the growth of coriander.

Local policy freedom: give and take? About the relationship between formal policy freedom, administrative capacity, scale and political change

Local policy freedom is often equated with the formal policy freedom of municipalities and thus with the formal boundaries that determine the local playing field. In this article, we question this approach. It is not clear to what extent formal policy freedom is a good measure for the ‘real’ policy freedom of municipalities, and thus for the policy freedom that municipalities use in policy implementation. Does more formal policy freedom necessarily lead to more used policy freedom? Moreover, not every municipality uses formal policy freedom in the same way. To indicate variance in policy discretion used, reference is often made to official capacity, scale and political changes. However, it is unclear to what extent these variables have an impact on local policy freedom. The authors investigate the link between formal and used policy freedom, official capacity, scale and political change on the basis of Flemish policy reform. Based on an analysis of financial data, they conclude that more formal policy freedom can be an incentive for more used policy freedom, but also that the explanatory power of administrative capacity, scale and political change is limited. In both research and policy, we need more attention for the value of social interaction, soft skills and networking.
Defining and applying a new approximation for the parametric probability densities of spherical particle profile sizes
Authors: Poliakova Ekaterina
Published: March 2022

A novel approximation for the parametric probability densities of spherical particle profile diameters is suggested. The spheres are approximated from solids obtained by rotating regular polygons around their axes of symmetry. This approximation facilitates using the maximum likelihood method in samples that have too few profiles for applying classical stereological approaches.

Published: March 2022

Traim, se pare, o viata mult mai complicata decat ne inchipuiam, cu doar putina vreme in urma. O viata in care certitudinile s-au imputinat dramatic, in care ne indreptam spre orizonturi necunoscute, incerte, nu tocmai aducatoare de liniste. Profesii care pareau definitiv consacrate s-au diluat si tind sa dispara, domenii intregi de activitate s-au bulversat si au devenit extrem de confuze, comunitatile in care traim se disperseaza, zi dupa zi, astfel incat lumea noastra, asa cum o stiam de multa vreme, a fost inlocuita, rapid si brutal, de o realitate in care ne miscam cu mare greutate si care ne solicita, pentru a supravietui, resursele cele mai bune de care dispunem. Vor fi, capacitatile noastre adaptative, suficient de puternice? Flexibilitatea noastra (mentala si comportamentala) ne va permite trecerea facila spre noua realitate post pandemica? Cum anume va arata, aceasta din urma? Care va fi locul nostru in lumea de maine? Iata doar cateva intrebari carora, pe alocuri, eforturile autorilor incearca sa le ofere raspunsuri.
Rostiri spirituale. Insemnari despre Parintele Dumitru Staniloae, Lucian Blaga si Mircea Eliade, in zarea traditiei mistice a Rasaritului crestin
Authors: Tiglea Adrian
Published: March 2022

Cartea lui Adrian Tiglea se constituie intr-o apologie a crestinismului si a spiritului sacru prezent in personalitatea omului. Modalitatea in care se desfasoara aceasta apologie, sub ochii cititorului, lasa impresia unei calatorii interioare a spiritualitatii; dar o calatorie in care suntem atrasi nu doar ca spectatori ai unei autentice etalari de eruditie, ci si ca purtatori tot mai lucizi ai unei spiritualitati trezite din obnubilarea cotidiana. Este acel fel aproape magic de a calatori in inalturi ramanand pe loc, insa revenind schimbati la propria conditie umana. Desfasurarea aceasta surprinde prin aceea ca se articuleaza din mers, ca intr-o aventura a descoperirii acelei comori ascunse in tarina, despre care vorbesc Scripturile (Evanghelia dupa Matei, 13:44). Ea il imbogateste interior pe orice cititor ce rezoneaza cu autorul in pretuirea acestei comori, atat sub aspect ideatic, cat si sub aspectul trairii crestine, caci, dupa cum ne spune Mantuitorul: „unde este comoara voastra, acolo va fi si inima voastra” (Evanghelia dupa Matei, 6:21). conf. univ. dr.

Uma análise da territorialização dos agrotóxicos na agricultura familiar de Guaranésia-MG
Authors: Melo Renata Vieira de
Published: March 2022

No sul de Minas Gerais, mais precisamente na Região Geográfica Imediata de Guaxupé- MG, encontra-se o município de Guaranésia-MG, onde a agricultura familiar está associada principalmente à produção de café e outras commodities, sendo esse município inserido na mundialização via cooperativas, e nesse sentido, a pressão econômica impõe aos agricultores familiares desafios para sua manutenção e reprodução de forma segura. Buscou-se compreender sobre as motivações na utilização de agrotóxicos, assim como, suas demandas de produção, a saúde destes produtores e de seus familiares, a disponibilidade de crédito agrícola para financiar a produção, suas percepções sobre o uso de agroquímicos, a rentabilidade agrícola e seus conhecimentos sobre produção orgânica. Para isso, utilizou-se a abordagem qualitativa como eixo fundamental e norteador das investigações, em complementaridade, utilizou-se a aplicação de questionário no trabalho de campo desenvolvido. Escolheu-se o contexto agropecuário de Guaranésia, por ser uma amostra da realidade sul mineira. Portanto, essa reflexão se justificou por buscar compreender a mundialização da agricultura, a territorialização do uso de agrotóxicos e consequentemente os impactos socioeconômicos para a agricultura familiar, e assim, poder elucidar a realidade agrária no município de Guaranésia-MG, como também no cenário nacional. Pode-se compreender a “força” e lobby do mercado e das cooperativas somados à atual inércia e retrocessos do Estado, nas esferas estadual e principalmente federal, nas políticas de valorização da agricultura familiar, compondo assim, obstáculos para a estruturação de uma política de alimentação saudável e segura para a população.
O histórico da rede urbana do Sul de Minas e a cidade média de Varginha
Authors: Andrade Alexandre Carvalho de , Figueiredo Rafaela Santos Costa de , Silva Rondinely Fernando Resende da
Published: March 2022

As cidades médias se caracterizam, dentre outras coisas, por suas posições intermediárias em uma rede urbana. Entretanto, com as dinâmicas econômicas, políticas, demográficas e socioculturais que incidem em um espaço geográfico, as redes urbanas se alteram, tanto com relação as posições hierárquicas de suas cidades, quanto pelas influências externas que nelas incidem. Este trabalho tem o objetivo de demonstrar os contextos históricos da rede urbana do Sul de Minas, com ênfase na posição da cidade média de Varginha. A referida região, localizada entre as importantes metrópoles de São Paulo, Rio de Janeiro e Belo Horizonte, apresenta efetivas relações com espaços externos, e deles recebe fortes influências por razões variadas, e, estas situações interferem nas dinâmicas dos centros urbanos regionais, e de suas funções e centralidades nas redes urbanas. Na ausência de uma cidade primaz, a rede urbana do Sul de Minas é descentralizada, tendo o protagonismo das cidades médias, dentre elas Varginha, classificada nas mais altas posições na hierarquia urbana regional, e que apresenta novas dinâmicas socioespaciais urbanas, dentre elas as novas centralidades.

Published: March 2022

O desenvolvimento da geografia como ciência se consolida no século XX, como uma forma de interpretação da sociedade em suas várias dimensões. Entre elas, destaca-se a dimensão cultural, que foi ganhando importância e alterando suas bases conceituais e metodológicas. Nesse sentido, o objetivo do artigo é realizar uma revisão bibliográfica sobre a geografia cultural, trazendo reflexões sobre seu papel dentro da ciência geográfica, com o intuito de mostrar as principais ideias, características e transformações. Para isso, investiga-se também o conceito de paisagem, que está associado à geografia cultural desde seu surgimento. Assim, a geografia tradicional dará ênfase a uma perspectiva material e descritiva da cultura na paisagem, e a partir da segunda metade do século XX, a nova geografia cultural agregará elementos simbólicos, imateriais e dos sentidos.
A importância das cidades médias e pequenas no ensino de geografia e as políticas curriculares
Authors: Silva André de Paula , Azevedo Sandra de Castro de
Published: March 2022

O Brasil possui uma quantidade significativa de cidades médias e pequenas. No entanto, a vivência da sala de aula enquanto professor de geografia mostrou que elas, geralmente, não são abordadas no ensino de Geografia.  Este trabalho tem como objetivo compreender como a Base Nacional Comum Curricular (BNCC) possibilita a abordagem da temática sobre cidades médias e pequenas no ensino de Geografia. Para alcançar este objetivo, com base no método materialista histórico dialético, utilizou-se como técnicas as análises bibliográfica e documental e aplicação de questionário via e-mail aos professores de Geografia da cidade média de Alfenas e da cidade pequena de Paraguaçu, ambas no Sul de Minas Gerais. Constatou-se que, em nível federal, as realidades dessas cidades são desconsideradas, prevalecendo um enfoque das escalas nacionais e globais. Dessa maneira foi possível constatar que a BNCC aborda um nacional que não representa a realidade de todo o território brasileiro e que também não é organizada de forma que estimule o professor a realizar uma abordagem mais explícita de cidades médias e pequenas.

The objective of this paper is to investigate which combination of parameters for the fingerling counting software results in the smallest Mean Absolute Error (MAE) and smallest Root Mean Squared Error (RMSE). For this, an image dataset called FISHCV155V was created and separated into training and test sets, where different combinations of parameters for the software were tested. From the obtained results were extracted individual performance metrics for each combination of parameters, such as MAE, Mean Square Error (MSE) and RMSE. Video frames were analysed comparing the parameter combination that obtained the best and worst results, in order to investigate the influence of such parameters in the performance of the software. From such results, it was concluded that the best combination reached 5.99 MAE and 9.96 RMSE.

Published: March 2022

Face verification approaches determine whether two given faces are from the same person. Recently, a new demand for face verification application which has become popular in commercial applications is the self-portrait and ID face matching, in which we compare the faces of a selfie shot by a subject and the face in a picture of her identification document. In this work, we proposed a novel approach for face verification in a cross-domain scenario, assuming we have only two images for each subject in the dataset. The method is based on siamese architecture with triplet-loss function. Experiments show the proposed model reaches good effectiveness for cross-domain face verification with low error rates, in comparison to other works of the literature.

Published: March 2022

Since the creation of the first magnetic resonance imaging (MRI) equipment in 1974, experts have been studying the continuous improvement of image quality. This work aims to study the types of background noise in images from extremity MRI system of high-field, mainly caused by Faraday Cage problems. Phantom images of 1T equipment were investigated for this study. For the acquisition of these images, a protocol called DQA (Daily Quality Assurance) was used. For this work, 45 MRI images were acquired, which were pre-classified by an expert, and analyzed by SNR, an index that quantifies the ratio between signal and image noise, and by the multivariate statistical methods PCA + MLDA. PCA served as a statistical filter, which considerably decreased the amount of input information for MLDA. When all main components were used, MLDA showed an accuracy of 93.33% and results that allowed to discriminate background noise from these images in complementarity with SNR.

Published: March 2022

Yeast counting is an important step in monitoring the fermentation process in sugarcane mills to optimize ethanol production. There is a need for a faster method to count viable cells in place of the fastidious and operator-dependent traditional method. In this paper, the application of a slightly modified version of the standard Circular Hough Transforms to automate the inoculated fermentation process of Saccharomyces cerevisae is reported. The results of several experiments with different preprocessing algorithms and parameter adjustments are presented. The resulting system will be part of a microbiological control procedure that is being developed to respond to Brazilian ethanol sugarcane mill's demands.

Published: March 2022

Support Vector Machines are a set of machine learning models that have great performance in several tasks as well as on image classification and object recognition. However, the proper choice of model's hyperparameters has a great influence on the outcomes and the general capacity performance. In this paper, we explore some different traditional auto-tuning processes to estimate σ hyper-parameter for SVMs Gaussian kernel. These processes are common and also implemented on standard software of data science languages. The paper considers some different situations on smile detection. The results are composed by simulation study, two benchmark image applications and a real video data application.
Methodology and Implementation of an Architecture for Egocentric Manual Interactivity in Monocular Augmented Reality

Published: March 2022

Investments in Augmented Reality (AR) have grown considerably in recent years. This advance is due to the increased use of AR in areas such as education, training, games and medicine. In addition, technological advances in hardware enable devices that, a few years ago, were unthinkable. A popular example is Microsoft Hololens 2, which allows the user to use their own hands as a means of interacting with an AR experience. However, a disadvantage from this device is its high cost due to several sensors. Thus, this project offers an AR architecture that uses only a monocular RGB camera as a sensor, allowing the user to interact with an AR experience using their hands to perform gestures similar to the Microsoft Hololens 2 architecture, where it is possible to handle a virtual object in the same way that a real object would be manipulated. The results obtained are promising, where the verification of the interaction of the hand with the virtual object worked in approximately 80% of the tests carried out, respecting the path defined by hand movement.

The daily life of preterm babies may be involved with long exposure to pain, causing problems in the development of the nervous system. In this context, an on-going area of research is the scientific development of image-based automatic pain detection systems based on several techniques, from anatomical measurements to artificial intelligence, they have generally two main issues: the categorization of the most relevant facial regions for identifying neonatal pain and the practical difficulty related to the presence of artifacts obstructing parts of the face. This paper proposes and implements an areas-of-interest automatic segmentation method that allows the creation of a novel dataset containing crops of neonatal faces relevant for pain classification, labelled by areas-of-interest and pain status. Moreover, we have also investigated the use of similarity matching techniques to compare each area-of-interest to the corresponding one extracted from a prototype face with no occlusion.t
Personality and Job Performance of Frontline Employees: A Meta-Analytic Review
Authors: Marcus Bernd , Heibrock Jule
Published: March 2022

Trends in personnel management of frontline employees’ (FLEs) imply that “soft skills” related to personality may be hardest to replace by technological advancements and, thus, become increasingly important. Building on the five-factor model (FFM) of personality, the present research therefore aimed at clarifying meta-analytically the role of personality for explaining FLEs’ job performance. Analyses covered 31 to 55 studies per FFM dimension (N = 6,514 to 10,139). It was found that all five dimensions showed moderate and generalizable relations either to subjectively, or to objectively, measured performance in sales jobs, whereas results were more mixed in non-sales jobs. We also found some evidence of positive time trends of validities. Theoretical and managerial implications include shifting the focus to (1) narrower and more job-related traits, (2) identifying more homogeneous clusters of non-sales jobs, (3) studying more complex personality performance relations, and (4) further monitoring time trends related to technological changes.
The Modalities of Essence and Ground
Authors: Werner Jonas
Published: March 2022

It is not a coincidence that every red rose is coloured. No rose can be red without being coloured. A red rose is coloured in virtue of its being red, its being coloured is metaphysically explained by its being red. This is, at least in part, underwritten by what it is for the rose to be coloured, by the nature – or essence – of its being coloured. If this is right, then questions concerning possibility and necessity, questions concerning metaphysical explanation, and questions concerning essence are systematically connected. This book proposes a unified account of metaphysical modality, grounding, and essence. It develops a semantic way to model essences as localised necessities that rule out worlds as impossible and uses it to account for grounding and metaphysical modality.

Published: March 2022

Trotz zahlreicher Studien zum erhöhten Viktimisierungsrisiko von Menschen mit einer schweren psychischen Erkrankung gibt es bisher wenig Erkenntnisse dazu, wie sich die Situation der Betroffenen nach erlebter Viktimisierung und die institutionelle Verarbeitung entsprechender Strafanzeigen darstellen. Ausgehend von diesen Fragestellungen wurden Erfahrungen nordrhein-westfälischer Richter*innen, Staatsanwält*innen und Polizeibeamt*innen mit einschlägigen Verfahren erforscht und mögliche Hürden für die Betroffenen, die einem erfolgreichen Verfahrensabschluss entgegenstehen, eruiert.

Die im Forschungsprojekt gewonnenen Erkenntnisse bildeten sodann die Grundlage für die Entwicklung konkreter Präventionsansätze und Hilfestellungen für Betroffene und Professionelle im Versorgungs- und Hilfesystem, um Konfliktpotentiale in der Begegnung zu reduzieren und eine sekundäre Viktimisierung der Opfer als Zeug*innen zu vermeiden.

Effects of Cognitive Dissonance Activation Emerged from Not Imposing Lockdown Restrictions on COVID-19-related Attitudes and Preventive Actions Considering the Role of Gender
Authors: Javanmard Shabnam
Published: March 2022

Background: During the pandemic of COVID-19, some countries imposed lockdown restrictions on their cities to stop the outbreak of the virus. However, this mandatory lockdown was not imposed by all countries. Objectives: The purpose of this study was to investigate the effects of the induced-compliance situation generated by not imposing the lockdown restrictions during the COVID-19 pandemic on individuals' COVID-19 perceived risk and practicing the World Health Organization preventive actions, considering the moderating role of gender. Methods: The research was conducted through a causal-comparative method. Participants were 320 social media users who were randomly selected to complete the justification of COVID-19 perceived risk and COVID-19 preventive action implementation questionnaires. Instruments' validity and reliability were confirmed through confirmatory factor analysis and Cronbach alpha. Results: The analysis of variance (ANOVA) showed significant interactive effects of gender and work attendance on the justification of COVID-19 perceived risk so that the highest rate of justification was applied by males who were required to attend their workplace physically. The ANOVA results showed the significant main effects of gender and work attendance on the action. Based on these findings, the lowest rate of preventive actions belonged to males and those who attended their workplace physically. Conclusions: It is concluded that not imposing the lockdown restrictions, other than its direct role in increasing social contacts and the probability of virus spread, also lowers preventive actions implementation. This could happen due to belief modification to eliminate the undesirable state of cognitive dissonance that emerged from the induced-compliance situations.
The Faithful and the Reasonable
Authors: Librová Hana , Galčanová Lucie , Kala Lukáš , Pelikán Vojtěch
Published: March 2022

This book follows the successful titles “The Colourful and the Green: Chapters on Voluntary Simplicity” and “The Half-Hearted and the Hesitant: Chapters on Ecological Luxury.” The author poses the question of why, at a time of continuing devastation of nature, people’s interest in nature conservation has been decreasing. Are the media to blame or is our numbness toward ecological problems rooted in our mental makeup that tends to supress unpleasant realities? The author also wants to find out why some people have remained faithful to nature. To get to the answers, she applies sociological, philosophical, psychological, and theological perspectives. An unexpected question that may surprise some readers then becomes: Actually, why should we protect nature when it can take care of itself? It is not weak; it is strong and cruel. Librová’s students Vojtěch Pelikán, Lucie Galčanová, and Lukáš Kala interview the children of “the Colourful,” too: have they inherited their parents’ modest lifestyle?
Twenty Years of Research into the Health Impacts of Native-themed Mascots: A Scoping Review
Authors: Watt Sierra , Record Ian , Roubideaux Yvette
Published: March 2022

Despite their recent high-profile removal by a handful of professional sports teams, Native-themed mascots continue to be a mainstay of professional, college, and youth athletics. To determine the extent of the literature on the health impacts on American Indians and Alaska Natives (AI/ANs) as a result of Native-themed mascots, we conducted a scoping review of primary research articles, utilizing the National Institute on Minority Health and Health Disparities (NIMHD) research framework as a guide to define health impacts broadly to include impacts on determinants of health and health disparities. Three databases were utilized, MEDLINE/PubMed, PsycINFO, and JSTOR, to identify the peer-reviewed literature for a twenty-year period that studied the health impacts of Native-themed mascots. We found 26 articles and books in the peer-reviewed literature and additional gray literature during the time period of 1999-2019. To better identify the relationship between Native-themed mascots and health impacts, we reviewed the articles by their focus on three groups: AI/ANs generally, AI/AN youth, and those that studied all races/ethnicities. The majority of research included in this review illustrates overall negative impacts of Native-themed mascots on health and its determinants that influence health and health disparities. Public health efforts should include review and replacement of harmful Native-themed mascots in professional and academic sports to avoid negative health impacts on AI/AN adults and youth.

The Asplenium coenobiale complex is distributed in Eastern Asia and Southeast Asia with its distribution center in southwestern China. In this study, we carried out a detailed morphological, cytological, and phylogenetic study by adding two samples from Danxia landform in Guangdong. The sequences of five chloroplast markers and one nuclear marker of the A. coenobiale complex were analyzed with maximum likelihood and Bayesian inference, respectively. The morphological and phylogenetic analyses support the recognition of a new species (A. danxiaense K.W.Xu sp. nov.) of the A. coenobiale complex from a cave of Danxia mountain, Guangdong province, southern China. This new species can be distinguished from A. coenobiale and A. pulcherrimum by having scales narrowly triangular to lanceolate, apex ending in a short apical tail, basal basiscopic pinnule usually largest, fertile segment scarce, and exospore length usually more than 50 μm and shows significant molecular differences from other species in this complex. A detailed description and illustrations are presented.

Published: March 2022

Work-place MusculoSkeletal Disorders (WMSD) continue to be the most significant source of industrial work force injuries. Exoskeletons are emerging as personal protective equipment (PPE) for sustained, repetitive, or intensive industrial tasks. This technical note describes and evaluates a proposed test method comprised of a novel testing apparatus, Position and Load Test Apparatus for Exoskeletons (PoLoTAE) designed and developed at the National Institute of Standards and Technology (NIST), to simulate a wide variety of industrial tasks. The test method used commercially available, low-cost, readily adaptable sensors, building materials, and an initial set of qualitative and analytical methods to evaluate perceived user comfort, exoskeleton fit for task, and impact of exoskeleton on task productivity. The study includes analysis of simple subjective and quantitative measurement methods to obtain perceived comfort, effort, exoskeleton support, fit, task rate, and task completion times. Lastly, we include the limitations of this study and suggested improvements towards the development of test methods for the use of exoskeletons for industrial tasks towards providing more information for validation of models to understand the human-exoskeleton kinetic and kinematic interactions.
Concept of Peer-to-Peer Lending and Application of Machine Learning in Credit Scoring
Authors:   University of Warsaw, Klimowicz Aleksy , Spirzewski Krzysztof
Published: March 2022

Numerous applications of AI are found in the banking sector. Starting from the front-office, enhancing customer recognition and personalized services, continuing in the middle-office with automated fraud-detection systems, ending with the back-office and internal processes automatization. In this paper we provide comprehensive information on the phenomenon of peer-to-peer lending in the modern view of alternative finance and crowdfunding from several perspectives. The aim of this research is to explore the phenomenon of peer-to-peer lending market model. We apply and check the suitability and effectiveness of credit scorecards in the marketplace lending along with determining the appropriate cut-off point. We conducted this research by exploring recent studies and open-source data on marketplace lending. The scorecard development is based on the P2P loans open dataset that contains repayments record along with both hard and soft features of each loan. The quantitative part consists in applying a machine learning algorithm in building a credit scorecard, namely logistic regression.
The Impact of Equity Capital on the Bank’s Profitability: Evidence From Vietnam’s Banking System

Published: March 2022

From 2008 to 2019, this research examines the effect of equity capital on the profitability of 24 Vietnamese commercial banks. The research findings indicate that, when ROAA and ROAE are used to measure the bank's profit, the equity capital ratio (CAP) has a statistically significant positive effect on the ROAA while having a negative effect on the ROAE. Between 2013 and 2019, the CAP variable has a positive effect on the ROAA and ROAE, indicating that banks with a larger equity capital ratio achieved higher profitability. Furthermore, the deposits-to-assets ratio (DTA) and loan-loss reserves ratio (LLR) both have a negative effect on both proxies for bank profitability, although bank size (SIZE) has a negligible effect on bank profits in the majority of circumstances. Additionally, the rate of GDP growth and inflation (INF) have a beneficial effect on the bank's profitability. The study's objective is to present some critical policy implications for bank executives about the importance of adequate equity capital for the bank's sustainability development.

Cholinergic and sympathetic counter-regulatory networks control numerous physiological functions, including learning/memory/cognition, stress responsiveness, blood pressure, heart rate, and energy balance. As neurons primarily utilize glucose as their primary metabolic energy source, we generated mice with increased glycolysis in cholinergic neurons by specific deletion of the fructose-2,6-phosphatase protein TIGAR. Steady-state and stable isotope flux analyses demonstrated increased rates of glycolysis, acetyl-CoA production, acetylcholine levels, and density of neuromuscular synaptic junction clusters with enhanced acetylcholine release. The increase in cholinergic signaling reduced blood pressure and heart rate with a remarkable resistance to cold-induced hypothermia. These data directly demonstrate that increased cholinergic signaling through the modulation of glycolysis has several metabolic benefits particularly to increase energy expenditure and heat production upon cold exposure.
Negation and uncertainty detection in clinical texts written in Spanish: a deep learning-based approach

Detecting negation and uncertainty is crucial for medical text mining applications; otherwise, extracted information can be incorrectly identified as real or factual events. Although several approaches have been proposed to detect negation and uncertainty in clinical texts, most efforts have focused on the English language. Most proposals developed for Spanish have focused mainly on negation detection and do not deal with uncertainty. In this paper, we propose a deep learning-based approach for both negation and uncertainty detection in clinical texts written in Spanish. The proposed approach explores two deep learning methods to achieve this goal: (i) Bidirectional Long-Short Term Memory with a Conditional Random Field layer (BiLSTM-CRF) and (ii) Bidirectional Encoder Representation for Transformers (BERT). The approach was evaluated using NUBES and IULA, two public corpora for the Spanish language. The results obtained showed an F-score of 92% and 80% in the scope recognition task for negation and uncertainty, respectively. We also present the results of a validation process conducted using a real-life annotated dataset from clinical notes belonging to cancer patients. The proposed approach shows the feasibility of deep learning-based methods to detect negation and uncertainty in Spanish clinical texts. Experiments also highlighted that this approach improves performance in the scope recognition task compared to other proposals in the biomedical domain.
