Authors: Shintri Shreedevi , Kumar Veerendrakumar
Published: August 2022

There are several points of intersections on findings of authors on social and personal characteristics which brought diverse changes in personal and professional life, impacted social organizations and human relations (Lévy, 2001). Human relations are built on cyber culture which is more evident during COVID-19. This led to new ways of thinking and communicating among the individuals. Despite the substantial body of literature concerning different management models aligned with technostress and employee’s job satisfaction in the business field have not yet grown significantly. This paper aims to analyze and establish relation between technostress and employee’s job satisfaction by fitting a structural equation modeling approach. Analyses of the measurement model confirmed its convergent validity, composite reliability and discriminant validity. The analysis of the structural model showed discrepancies in some constructs, which, to some extent, disconfirm theoretical assumptions regarding the systemic and balanced relationships among the concepts. On the other hand, the results confirm the relationship between the variables. The study revealed the variables having impact on technostress, job satisfaction and organisational commitment in different proportions. Technostress also showed to have impact on job satisfaction and organisational commitment. The study used Structural Equation Modeling (SEM) method to find the relationship between technostress creators and Job satisfaction. The findings showed a negative impact of technostress creators on job satisfaction.

The occurrence of the cis/trans geometric isomerism of myxoxanthophyll and 4-ketomyxoxanthophyll in the cyanobacterium Anabaena sp. PCC7120
Authors: Żbik Paweł , Malec Przemysław
Published: August 2022

The cyanobacteria of the genus Anabaena have recently been recognized as a potential source of secondary metabolites of pharmacological and biotechnological importance. In particular, myxoxanthophylls – specific carotenoid glycosides that accumulate in cyanobacterial cells, are attracting increasing interest. Anabaena (Nostoc) sp. PCC7120, a filamentous, mesophilic, nitrogen-fixing cyanobacterium, is a model organism used in biochemical and genetic studies. The carotenoid pool of Anabaena sp. PCC7120 consists of five main species of pigments, namely β-carotene, echinenone, canthaxanthin and two derivatives of myxoxanthophyll: myxoxanthophyll ((3R,2‘S)-myxol 2’-fucoside) and 4-ketomyxoxanthophyll ((3S,2’S)-4-ketomyxol 2’-fucoside). Recent findings show that the carotenoid biosynthesis pathway functions in Anabaena sp. PCC7120 cells are affected by environmental factors. Specifically, the balance between β-carotene and ketocarotenoids alters according to the temperature conditions. In this study, a new method, based on single-step liquid adsorption chromatography was developed and applied to separate a fraction containing myxoxanthophyll and 4-ketomyxoxanthophyll from Anabaena sp. PCC7120 cells. It was found that this method allowed a high purity fraction of carotenoid glycosides to be obtained from pigment pools as extracted from cyanobacterial cells. The subsequent analysis using the methods HPLC and LC/MS demonstrated that this fraction consists of a mixture of compounds with different retention times. On the basis of their fragmentation spectra and optical properties, these compounds were identified as geometrical isomers of myxoxanthophyll and 4-ketomyxoxanthophyll, including the dominant all-trans forms and less abundant cis forms. Proposals regarding the structures of myxoxanthophyll isomers are made.

Published: August 2022

Faced with the widespread digitalization in educational services, every educational organization has to strive to meet modern-day quality and security standards for both information and other assets. The education organizations should invest in a methodology that identifies system flaws and, as a result, opportunities for improvement. To protect the educational organization's information assets from internal, external, intentional, or unintentional threats, an "Information Security Policy" should be developed. Effective data management necessitates not only the identification of data requirements but also security issues. Educators and students should be subject to policies that define and impose conditions in a variety of sensitive areas.

Authors: O'Kane Cavan , Piechowski Kara , Hoff Abigail , Fang Wei , Mallow Zebulun , Marshalak Patrick , Burwell Sheena
Published: August 2022

Purpose: Intravenous drug use (IVDU) is an independent risk factor for infective endocarditis (IE). IVDU-related IE is associated with poor clinical outcomes, such as infection-related and drug abuse-related readmissions and mortality. Critical interventions to treat addiction, such as medication for opioid use disorder (MOUD) with buprenorphine, may prevent these unfavorable outcomes. This study aimed to establish the effectiveness of buprenorphine prescriptions at hospital discharge for patients admitted for IVDU-related IE. Methods: A single center, retrospective cohort study evaluated the effectiveness of discharge prescriptions of buprenorphine in adult patients (≥18 years of age) with OUD and IVDU-related IE. Outcomes of 30-day readmissions, 180-day readmissions, and mortality were compared to a cohort of patients who were not prescribed buprenorphine at hospital discharge. Results: The primary endpoint of all cause 30-day readmission was lower in patients who received buprenorphine (n=11/122, 9%) at hospital discharge for IVDU-related IE compared to those who did not (n=9/48, 19%), although not statistically significant (unadjusted OR 0.429, 95% CI 0.165-1.138, p=0.082). After accounting for intensive care admission, infusion unit admission, and psychiatry consultation, the odds of all cause 30-day readmission were statistically lower in patients prescribed buprenorphine (adjusted OR 0.337, 95% CI 0.125-0.909, p=0.029). Additionally, significantly more patients prescribed buprenorphine at discharge followed-up in an outpatient treatment program, 57% and 15% respectively (p<0.001). Incidence of readmission at 180 days and mortality was similar between the two cohorts. Conclusions: This study demonstrated that buprenorphine prescriptions at hospital discharge in patients with OUD admitted for IVDU-related IE were effective at decreasing readmission rates at 30 days and increasing outpatient treatment follow-up. Therefore, it is imperative that an emphasis on addiction-focused interventions, such as initiating buprenorphine, be considered in this patient population at hospital discharge to decrease hospital readmissions and engage patients in outpatient treatment for OUD. This study is the first to evaluate the effects of MOUD on readmission rates for patients hospitalized with IVDU-related IE and contributes to the growing body of evidence to support addiction-focused interventions for this unique patient population.
La dimensión política del consumo: aproximaciones teóricas para abordar problemas contemporáneos
Authors: Diaz Rosaenz Micaela
Published: August 2022

Este trabajo tiene como objetivo presentar desde una mirada crítica los estudios sobre el consumo y su dimensión política, poniendo en discusión el cuestionado binomio ‘ciudadano-consumidor’. Los marcos conceptuales más frecuentes se han ocupado de la relación entre política nacional y consumo con sesgos muy marcados: con énfasis en Europa y Estados Unidos a mediados del siglo XX y también como forma de activismo y participación. Aquí se busca revisar estas perspectivas y recuperar aquellas que sean útiles para abordar las particularidades de los procesos latinoamericanos, con foco en Argentina y Brasil. Es, por lo tanto, de naturaleza teórica y tiene como finalidad explicar por qué es relevante estudiar a los regímenes políticos y a la ciudadanía desde la perspectiva del consumo como una forma válida para abordar los problemas sociales contemporáneos en la región.

Authors: Meena Rajmohan , Kumari Vinod
Published: August 2022

Background: Jhunjhunu district has semi-arid climatic condition which is favorable to flourish ground beetles. Diversity of ground beetles are beneficial to agricultural ecosystem as carabid beetles are prominent decomposers and reduce population of insect pest specially, caterpillars. The present study aimed to document diversity of ground beetles which will provide first even preliminary information needed for their conservation and use in integrated pest management program. Methods: Sampling was carried out in Jhunjhunu district from January 2021 to December 2021. Four sampling sites viz., Site-A (agriculture land), Site-B (Plains are relatively flat land which is dominated by grasses, herbs and shrubs), Site-C (rocky area) and Site-D (blanks of water bodies) were selected based on different habitats situation. Carabid beetles were collected using pitfall trap, hand picking and light trap and identified by valid taxonomic keys. Result: Diversity indices authenticated a good diversity and abundance of ground beetles in the district. A total of 956 individuals of carabid beetles, representing 28 species and 19 genera belonging to 11 subfamilies viz. Harpalinae (7 species), Trechinae (7 species), Brachininae (3 species), Scaritinae (3 species), Lebiinae (2 species), Paussinae (1 species), Anthiinae (1 species), Carabinae (1 species), Pterostichinae (1 species), Platyninae (1 species), Cicindelinae (1 species) under Carabidae family were collected and identified from various habitats of study area. On the basis of total number of individuals Dromius quadrimaculatus is the most dominant species and constituted 18.62% of total beetles followed by Chlaenius bimaculatus (8.05%), Tetragonoderus intermedius (7.64%) Lophyra differens (6.80%) and Bembidion ambiguum (5.02%). The highest diversity was observed at Site-B (H=2.72, J=0.83, M=4.43) followed by Site-A (H=2.72, J=0.83, M=4.08), Site-C (H=2.52, J=0.90, M=3.48) and Site-D (H=2.25, J=0.87, M=2.25).

Background: The prohibition of the use of antibiotics in lamb feeding requires the search for natural alternatives that can improve productive performance and ruminal fermentation parameters. Herbal mixtures can function as cost-effective substitutes for growth promoters since an extraction or purification process is not required. Methods: An experiment was conducted to evaluate the effect of Chebulic myrobalan, Terminalia bellirica and Azadirachta indica on the productive performance of finishing lambs. Thirty-six Hampshire x Suffolk male lambs (initial body weight (BW) 23.52±3.67 kg), in individual crates, were used for 45 days of evaluation after 15 days adaptation and were randomly assigned to treatments which consisted of dietary inclusion of the feed plant additive at 0.000, 0.250, 0.375 and 0.500% of dry matter (DM). Rations were sampled for DM, ash and crude protein (AOAC, 2005), neutral and acid detergent fibre (according to van Soest, 1991) analysis and metabolizable energy was estimated. The animals were weighed on days 1, 15 and 45 before feeding and the average daily gain (ADG) and feed conversion rate were calculated by daily recording of the dry matter intake. Contrasts no orthogonal were used to test linear or quadratic effects of the herbal mixture with initial body weight (BW) as a covariate for ADG and final BW. Result: There was no effect (P greater than 0.05) of herbal mixtures on ADG, final BW, feed efficiency, DM intake and feed conversion by phytobiotic dietary inclusion. Ruminal pH (P=0.07) increased quadratically in response to the herbal mixture dietary concentration. The acetate increased and propionate reduced, both quadratically (P less than 0.05). The evaluated doses of the polyherbal additive did not influence growth and feed efficiency of lambs.

Published: August 2022

Este artigo versa sobre a temática da formação inicial e continuada docente e as interlocuções com as Políticas de Educação Especial, na perspectiva da Inclusão. As Diretrizes Curriculares Nacionais (DCN), estabelecidas pelo Conselho Nacional de Educação (CNE), propõem como devem ser as políticas e ações educacionais em relação à formação docente, tanto inicial quanto continuada. Dois aspectos fundamentais dessas diretrizes são: a eminência de uma efetiva articulação entre a formação inicial e a formação continuada, e a consolidação de competências docentes para a construção de uma sociedade democrática e inclusiva. Para tanto, formação inicial e formação continuada devem prever processos formativos coerentes com esses aspectos fundamentais, além de problematizar as políticas de educação especial na perspectiva da inclusão. Diante disso, apresentamos uma revisão sistemática sobre os eixos temáticos supracitados e a experiência de construção do estágio obrigatório supervisionado no Ensino Fundamental, Eixo Alfabetização, no Curso de Pedagogia, na modalidade de Educação a Distância (EaD), da Universidade do Oeste Paulista, visando compreender em que medida essa experiência atende aos pressupostos teóricos e legais. Os resultados demonstram que, do ponto de vista da produção de conhecimento no Brasil, nos últimos anos, a perspectiva da inclusão escolar é prevista como componente formativo, tanto na formação inicial quanto na formação continuada. Na experiência descrita, a vivência do estágio supervisionado obrigatório, no Eixo Alfabetização, denota uma perspectiva de integração formação inicial e rede de educação básica e a construção de conhecimentos sobre Inclusão Escolar e/ou apoio e valorização das diferenças.
EQUIDADE NA EDUCAÇÃO STEM PARA TODOS OS GÊNEROS
Authors: Moreira Raphaell
Published: August 2022

Talento é distribuído igualmente por todos os grupos socioculturais, porém quando se trata do acesso a oportunidades, as barreiras sistêmicas são visíveis. Isso é particularmente verdadeiro nas profissões envolvendo Ciência, Tecnologia, Engenharia e Matemática (STEM). A sub-representação de grupos marginalizados nos contextos STEM é generalizada. Negros, índios e minorias sexuais ou de gênero e indivíduos com deficiência continuam com menor probabilidade de serem integrados com sucesso nos cursos e profissões de STEM. Esses indivíduos podem ser questionados sobre sua competência, desafiados em conhecimentos científicos e, consequentemente, invisibilizados como cientistas. Dezenas de relatórios e estudos empíricos documentam que essas experiências são muito comuns como características do cenário contra o qual o desenvolvimento acadêmico e de carreira se desenrola para muitos de grupos sub-representações. Infelizmente, a boa ciência pode ser dificultada em ambientes não civis e negligentes. A ampla integração de todos os segmentos da sociedade nos cursos STEM trará inovações e benefícios sociais significativos para uma sociedade mais sustentável. Mas como o acesso e a oportunidade podem ser facilitados em ambientes de afirmação em apoio a um modelo de desenvolvimento de talentos STEM para todos? Neste artigo, será apresentado uma visão geral sobre os problemas enfrentados pelos grupos marginalizados e sugestões de como podemos trabalhar para reduzir barreiras sistemas para uma educação STEM mais equitativa para todos os gêneros.

1. Metallothionein is a protein found in seagrass and functions to bind to heavy metals so as not to damage the seagrass body tissue
 
Abstract
Lead is a very dangerous heavy metal for organisms because it is carcinogenic, can cause mutations, takes a long time to decompose and has unchanging toxicity. This study on the seagrass Cymodocea serrulata aimed to determine the metallothionein expression quantitatively using the Elisa (Enzyme-Linked Immunosorbent Assay) method and describe the surface structure of C. serrulata roots, rhizomes, and leaves that were exposed to lead using SEM and EDX Mapping methods. The results showed that metallothionein was abundant in C. serrulata tissues (leaves>roots>rhizomes) in both South Bangka and Ketawai Island. SEM showed changes in the morphology and cell size of C. serrulata exposed to lead. EDX and Mapping showed the substance elements found in seagrass tissue. Pb was detected in C. serrulata roots (0.22%) and leaves (0.6%) in South Bangka. This indicates that the seagrass plants are able to absorb heavy metals into their body tissues.

Marine brown seaweed are known as one of the potential biological agents to be developed as functional food and medicinal sectors. This study aims to examine the concentration of heavy metals (Pb, Cd, Hg, and As) in brown algae (Sargassum aquifolium, Padina australis, and Turbinaria ornata.) and the possible exposure to health risks caused by consumption.  Heavy metal concentrations were determined using Atomic Absorption Spectroscopy (AAS) on brown seaweed samples obtained from three different sites. The average concentration of heavy metals in the dry weight of brown seaweed remains within the guidelines established by The Food and Drug Supervisory Agency (BPOM) Number 32 of 2019 concerning the Safety and Quality of Traditional Medicines, which is then used to calculate the estimated daily intake (EDI), target hazard quotient (THQ and TTHQ), and target cancer risk (TCR) for arsenic associated with food exposure to potentially toxic metallic elements. Each species of brown seaweed has a THQ and TTHQ level of <1, indicating that one or more toxic metal elements in the same meal provide no significant non-carcinogenic risk. The TCR for arsenic in these seaweeds are all less than 1 x 10-4, indicating no cancer risk. There are no chronic health hazards related with the ingestion of brown seaweed harvested from the coast of Sanur Beach at Denpasar, Bali.

Based on genetic variation this species-complex are polymorphic and cryptic. In the present study, the genetic diversity and stock structure of loliginid squid U. duvauceli is investigated using a mitochondrial gene cytochrome oxidase subunit I (COI). Samples were collected by hand-jigging onboard of an 8hp small fisher-boat equipped with a few lamps during May to August 2015, May 2016 and August to November 2018. Sample collection started at dusk until midnight. The attractor was a weighed-quill attached to nylon string, manually immersed into the water and pulled quickly and continuously for about 3-5 minutes at each effort. The determination was conducted with BLAST. Phylogenetic analysis showed two separate clusters with 100% bootstrap value, in which cluster II from Palabuhanratu has divergences of 5.9 - 7.0%, compared to cluster I.  Genetic variations exist within and among individuals over the locations. Palabuhanratu individuals have the highest polymorphism levels compared to other locations as shown by 40 segregating sites (S). Frequencies of A, C, G, and T in mtDNA of the 20 specimens U. duvauceli are biased toward A and T, with T being the most favoured and G being the least favoured nucleotide. All specimen showed no amino acid frequency for glutamic acid and all four individuals in cluster II (south coast) also have no amino acid frequencies for aspartic acid and valine as well.

The ability of bacterial strains to adhere to epithelial cells of shortfin eel epithelial cells was demonstrated
The bacterial strains' proteolytic, cellulolytic, and lipolytic activities were detected
Oral administration of the bacterial cocktail lowered overall viable bacterial count but did not affect the shortfin eel's intestinal histological characteristics

 
Abstract
Aquaculture of the shortfin eel (Anguilla bicolor bicolor) has been plagued by low survival and growth due to the low tolerance to water quality and feed. The microbiota and shape of the fish intestinal tract influence the immune and digestive systems. The use of bacterial probiotics is fascinating to enhance the digestion system. This study aimed to characterize bacterial probiotic candidates' safety and potential probiotic features for shortfin eel (A. bicolor bicolor) aquaculture. The safety, adherence, and enzymatic activity of three bacterial strains (Bacillus sp. PCP1, Lactococcus sp. JAL 37, and Enterobacter sp. JC05) were investigated. An oral application test was performed on shortfin eel (n=880, 15 g) every four days with 0, 3x103, 3x105, and 3x107 CFU/g diet dosages in quadruplicates for two months. At the end of the experiment, total cultivable bacteria and intestinal morphology were assessed. Based on the hemolytic test and intraperitoneal injection, the bacterial strains were considered harmless. In an in vitro investigation, the bacteria attached to shortfin eel intestinal epithelial cells. An agar diffusion method validated the proteolytic, lipolytic, and cellulolytic activities. In vivo feeding tests with the bacterial cocktail lowered the total viable bacteria in the gut while preserving the gut histology. Bacterial strains of the present study are potential probiotic candidates for shortfin (A. bicolor bicolor) aquaculture.

Antimicrobial resistance is on the rise, and there aren't enough new treatments to combat it. This might send the modern world back to the pre-antibiotic age. The molecular hybrids of pyrazolo[3,4-b]pyridine and triazole have been designed, synthesized, and analyzed for their drug-like molecule nature and in vitro analyses for their inhibition potentials against S. Aureus and K. Pneumoniae. The compounds CY-R2-25 and CY-R2-28 have been identified as the high potential molecules in this series based on in vitro experiments. CY-R2-25 has zone of inhibition values of 15 0.82 and 14 0.7, whilst CY-R2-28 has the zone of inhibition values of 18 0.95 and 16 0.82 against S. Aureus and K. Pneumoniae, respectively. MIC and MIB values for CY-R2-25 and CY-R2-28 against S. Aureus and K. Pneumoniae are 0.25 and 0.5, respectively.

Objective: One of the major causes of cerebral ventricular shunt failure is proximal catheter occlusion. We describe a novel ventricular cerebrospinal fluid (CSF) flow replicating system that assesses pressure and flow responses to varied degrees of catheter occlusion. Methods: Ventricular catheter performance was assessed during conditions of partial and complete occlusion. The catheters were placed into a three-dimensionally printed phantom ventricular replicating system. Artificial CSF was pumped through the ventricular system at a constant rate of 1 ml/min to mimic CSF flow, with the proximal end of the catheter in the phantom ventricle. Pressure transducer and flow rate sensors were used to measure intra-phantom pressure, outflow pressure and CSF flow rates. The catheters were also inserted into silicone tubing and pressure was measured in the same manner for comparison with the phantom. Results: Pressure measured in the phantom ventricle did not change when the outflow of the ventricular catheter was partially occluded. However, the intraventricular phantom pressure significantly increased when the outflow catheter was 100% occluded. Flow through the catheter showed no significant difference in rate with any degree of partial occlusion of the catheter. At the distal end of the partially occluded catheters, there was less pressure compared with the nonoccluded catheters. This difference in pressure in partially occluded catheters correlated with the percentage of catheter hole occlusion. Conclusions: Our model mimics physiological dynamics of the CSF flow in partially and completely obstructed ventricular catheters. We found that partial occlusion of the catheter had no effect on CSF flow rate, but did reduce outflow pressure of the catheter.
A New Data Processing Pipeline for Generating Sea Ice Surface Roughness Products from the Multi-angle Imaging SpectroRadiometer (MISR) Imagery

Published: August 2022

Sea ice roughness can serve as a proxy for other sea ice characteristics such as ice thickness and ice age. Arctic-wide maps that represent spatial patterns of sea ice roughness can be used to better characterize spatial patterns of ice convergence and divergence processes. Sea ice surface roughness can also control and quantify turbulent exchange between sea ice surface and atmosphere and therefore influence surface energy balance at the basin scale. We have developed a data processing system that produces georeferenced sea ice roughness rasters that can be mosaicked to produce Arctic-wide maps of sea ice roughness. This approach starts with Top-of-Atmosphere radiance data from the Multi-angle Imaging SpectroRadiometer (MISR). We used red-band angular data from three MISR cameras (Ca, Cf, An). We created a training data set in which MISR pixels were matched with co-located and concurrent lidar-derived roughness measurements from the Airborne Topographic Mapper (ATM). We used a K-nearest neighbor algorithm with the training data to calibrate the multi-angle data to values of surface roughness and then applied the algorithm to Arctic-wide MISR data for two 16-day periods in April (spring) and July (summer). After georeferencing the roughness rasters, we then mosaicked each 16-day roughness dataset to produce Arctic-wide maps of sea ice roughness for spring and summer. Assessment of the results shows good agreement with independent ATM roughness data, not used in model development. A preliminary exploration of spatial and seasonal changes in sea ice roughness for two locations shows the ability to characterize the roughness of different ice types and the results align with previous studies. This processing system and its data products can help the sea ice research community to gain insights into the seasonal and interannual changes in sea ice roughness over the Arctic.
